Braskem SA
A Brazilian petrochemical maker that produces the thermoplastic resins — polyethylene, polypropylene, and PVC — found in everyday packaging, auto parts, pipes, and building materials, sold to customers in dozens of countries. It was created in 2002 by merging six Brazilian petrochemical firms, and its name "Braskem" blends "Brasil" with "chem." A quirky standout: its "I'm green" plastic is made from renewable sugarcane yet is chemically identical to regular polyethylene, so it can be recycled in the same streams.

ABOUT MARKET RISK Market risk is the potential loss arising from adverse changes in market rates and prices. We have exposure to market risks arising from our day-to-day business activities. These risks are beyond our control and consist, principally, in the possibility that changes in interest rates, exchange rates, or commodity prices will adversely affect the value of our financial assets and liabilities or future cash flows and earnings. In order to mitigate the market risks to which we are exposed, we have used, and we may use, foreign currency, interest rate and commodity derivative instruments, as well as cash and receivables. As of December 31, 2025, the Company held a total notional amount of put options of R$2,526 million (US$482 million), with an average strike price of R$5.24/US$ and notional amount of call options of R$2,526 million (US$323 million), with an average strike price of R$7.82/US$. We assess the potential and consolidated impact of market risks and seek to mitigate those risks following our risk management policy. 209 Table of Contents Our current risk management policy, adopted on March 30, 2017, by our Board of Directors and updated in July, 2019 and in August, 2022 covers cash flow management and liquidity, investment of cash and cash equivalents, funding activities and guarantees, and management of foreign exchange and commodity risks. This policy reflects our conservative financial practices and risk management procedures. Its objective is to manage and anticipate risks by continuously evaluating several key factors, including the overall financial health of our Company, any financial operations we have with related parties, our ratings, counterparty risk and hedging strategy. Additionally, the policy aims to ensure the alignment of the objectives of the financial teams with the overall objectives of Braskem. We do not enter into derivative transactions with speculative purposes. As of December 31, 2025, we had R$6.4 billion (US$1.2 billion) in foreign currency-denominated cash and cash equivalents, including the aggregate amount of R$233 million (US$42.3 million) of Braskem Idesa’s cash and cash equivalents. Interest Rate Risk Our variable interest rate exposure is primarily subject to the variations of the term SOFR rate and, for real-denominated borrowings and short-term cash investments, variations of the CDI rate and IPCA rate. With respect to Brazilian interest rates: · the short-term domestic CDI rate increased to 14.90% per annum as of December 31, 2025, from 12.15% per annum as of December 31, 2024, and 11.65% per annum as of December 31, 2023; and · IPCA recorded in 2025 was 4.26%, decreasing from 4.83% in 2024 and 4.62% in 2023. The table below provides information about our significant interest-rate sensitive instruments: 210 Table of Contents Payment Schedule—Breakdown by Type of Interest Rate As of December 31, 2025 Expected Maturity Date 2026 2027 2028 2029 2030 Thereafter Total Fair Value(1) (in millions of reais, unless otherwise indicated) Liabilities: Loans and financings: Fixed rate, denominated in U.S. dollars 954.1 - 6,453.2 - 8,215.1 23,413.5 39,035.9 15,266.2 Average interest rate 6.7% - 4.5% - 4.5% 7.5% Fixed rate, denominated in Euro - - - - - - - 40.1 Average interest rate - - - - - - Variable rate, denominated in U.S. dollars (SOFR) 6,780.3 1,313.8 435.5 271.1 123.8 61.9 8,986.4 6,460.4 Average interest rate (over SOFR) 2,1% 1,6% 1,4% 1,5% 2,0% 2,0% Bond Idesa fixed rate, denominated in U.S. dollars 397.4 - - 4,954.5 - 6,606.0 11,957.9 6,733.8 Average interest rate 7.3% - - 7.5% - 7.0% Variable rate, denominated in U.S. dollars (Braskem Idesa) 320.9 89.5 1,746.8 523.0 - - 2,680.2 2,080.9 Average interest rate 8.3% 7.8% 7.8% 12.1% - - Fixed rate, denominated in reais 2.5 - - - - - 2.5 1.8 Average interest rate 6.5% - - - - - Variable rate, denominated in reais - - - - - - - - Average interest rate (over TR) - - - - - - Variable rate, denominated in reais 561.0 330.2 - 1,859.7 113.4 226.9 3,091.2 1,592.5 Average interest rate (over CDI) 1,6% 1,3% - 1,7% 2,0% 2,0% Variable rate, denominated in reais 50.7 47.6 751.4 103.7 103.7 60.1 1,117.2 737.2 Average interest rate (over IPCA) 6.0% 6.0% 5.6% 5.8% 5.8% 5.6% Total Loan and financings 9,066.9 1,781.2 9,386.9 7,711.9 8,556.0 30,368.4 66,871.4 32,912.9 Assets: Cash and cash equivalents and other instruments: Fixed rate, denominated in foreign currency 9,073.9 - - - - - 9,073.9 9,073.9 Variable rate, denominated in reais 2,792.7 - - - - - 2,792.7 2,792.7 Total cash and cash equivalents and other investments 11,866.5 - - - - - 11,866.5 11,866.5 (1) represents the net present value of the future cash flows from the obligations converted into reais at fair market value as of December 31, 2025. 211 Table of Contents In the event that the average interest rate applicable to our financial assets and debt in 2026 is one percentage point higher than the average interest rate in 2025, our financial income would increase by R$119 million and our financial expenses would increase by R$669 million. Foreign Currency Exchange Rate Risk Our liabilities with exposure to foreign currency exchange rate risk are mainly U.S. dollar-denominated. To partially offset the risk of a devaluation of the real against the U.S. dollar, we currently maintain liquid assets denominated in U.S. dollars available. Additionally, in order to provide a better representation of the actual exchange rate risk related to future exports, we designated part of our U.S. dollar-denominated liabilities as a hedging instrument, implementing the hedge accounting treatment since May 1, 2013. We borrow in the international markets to support our operations and investments; we have exposure to market risks from changes in foreign exchange rates and interest rates. The table below provides information about our significant foreign currency exposures: Payment Schedule—Breakdown by Currency As of December 31, 2025, Expected Maturity Date 2026 2027 2028 2029 2030 Thereafter Total Fair Value(1) (in millions of reais) Liabilities: Loans, financings and trade payables: Loans and financings denominated in U.S. dollars 8,452.8 1,403.4 8,635.5 5,748.5 8,338.9 30,081.4 62,660.5 47,239.5 Accounts payable denominated in U.S. dollars 1,358.3 - - - - - 1,358.3 1,358.3 Total loans, financings and trade payables 9,811.1 1,403.4 8,635.5 5,748.5 8,338.9 30,081.4 64,018.8 48,562.6 Assets: Cash and cash equivalents and other investments Denominated in foreign currency 9,073.9 - - - - - 9,073.9 9,073.9 Total cash and cash equivalents and other investments 9,073.9 - - - - - 9,073.9 9,073.9 Hedge Accounting: Hedge Accounting designated Exports/Sales - - - - - - - - (1) Represents the net present value of the future cash flows from the obligations converted into reais at fair market value as of December 31, 2025. 212 Table of Contents Our foreign currency exposures give rise to market risks associated with exchange rate movements of the real against the U.S. dollar. Foreign currency-denominated liabilities as of December 31, 2025, consisted primarily of U.S. dollar-denominated debt. Our U.S. dollar-denominated debt, including short-term debt and current portion of long-term debt, was R$61.9 billion (US$11.3 billion) as of December 31, 2025, and $64.2 billion (US$10.4 billion) as of December 31, 2024. This foreign currency exposure is represented by debt in the form of notes, bonds, pre-export finance facilities and working capital loans. Our cash and funds available in U.S. dollars partially protect us against exposure arising from the U.S. dollar-denominated debt. Similarly, revenue from future sales and exports partially offsets this foreign currency exposure for U.S. dollar-denominated debt, and we therefore adopted hedge accounting treatment to provide a better representation of our actual exposure. Since 2016, Braskem has recognized the exchange rate variation, held on “Other Comprehensive Income,” to the income statement, following the future sales and exports designation schedule. In November 2025, Braskem Idesa defaulted on interest due on the bond due in 2029. As a result of the breach of contractual terms under the financing arrangements that supported the hedging relationships, Braskem Idesa discontinued the application of hedge accounting In December 2025, Braskem, reassessed, for accounting purposes, the fulfillment of the “highly probable transactions” criterion required under IFRS 9 for the continuation of its hedge accounting program, which resulted in the prospective discontinuation, as of December 31, 2025, of the hedge accounting related to certain future revenues of Braskem S.A. For more information, see note 18.9 to our audited consolidated financial statements elsewhere in this annual report. In the event that the real depreciated by 10% against the U.S. dollar during 2025 as compared to the real/U.S. dollar exchange rate as of December 31, 2024, our financial expenses indexed to the dollar in 2025 would have increased by R$6.3 billion, and our financial income would have increased by R$934 million. Commodity Prices We do not hedge the exposure to the price of naphtha, our principal raw material. This is, in part, because a portion of our sales are exports payable in foreign currencies and linked to the international market prices of these commodities denominated in U.S. dollars and, in part, because the prices of our polyethylene, polypropylene and PVC products sold in domestic markets generally reflect changes in the international market prices of these products denominated in U.S. dollars, converted into reais. In periods of high volatility in the U.S. dollar price of naphtha or the real/U.S. dollar exchange rate, there is usually a lag between the time that the U.S. dollar price of naphtha increases or the U.S. dollar appreciates and the time that we can effectively pass on the resulting increased cost in reais to our customers in Brazil. Accordingly, if the U.S. dollar price of naphtha increases precipitously or the real devalues precipitously against the U.S. dollar in the future, we may not immediately be able to pass on all of the corresponding increases in our naphtha costs to our customers in Brazil, which could materially adversely affect our results of operations and financial condition. See “Item 3. D Risk Factors—Risks Relating to Us and the Petrochemical Industry.”

Exchange Rates The current laws and regulations governing the Brazilian foreign exchange system allow the purchase and sale of foreign currency and the international transfer of reais by any person or legal entity, regardless of the amount, subject to certain regulatory procedures. Since 1999, the Central Bank has allowed the U.S. dollar-real exchange rate to float freely, and, since then, the U.S. dollar-real exchange rate has fluctuated considerably. In the past, the Central Bank has intervened occasionally to control unstable movements in foreign exchange rates. We cannot predict whether the Central Bank or the Brazilian government will continue to permit the real to float freely or will intervene in the exchange rate market through the return of a currency band system or otherwise. The real may depreciate or appreciate against the U.S. dollar substantially. Furthermore, Brazilian law provides that, whenever there is a serious imbalance in Brazil’s balance of payments or there are serious reasons to foresee a serious imbalance, temporary restrictions may be imposed on remittances of foreign capital abroad. We cannot assure you that such measures will not be taken by the Brazilian government in the future. See “—Risk Factors—Risks Relating to Brazil—Brazilian government exchange control policies could increase the cost of servicing our foreign currency-denominated debt, adversely affect our ability to make payments under our foreign currency-denominated debt obligations and impair our liquidity” and “—Risk Factors—Risks Relating to Our Equity and Debt Securities—If holders of the ADSs exchange them for class A preferred shares, they may risk temporarily losing, or being limited in, the ability to remit foreign currency abroad and certain Brazilian tax advantages.” ITEM 3.A (Reserved) ITEM 3.B CAPITALIZATION AND INDEBTEDNESS Not applicable. ITEM 3.C REASONS FOR THE OFFER AND USE OF PROCEEDS Not applicable. ITEM 3.D RISK FACTORS Summary of Risk Factors Below is a summary of certain factors that make an investment in our securities speculative or risky. Importantly, this summary does not address all of the risks and uncertainties that we face. This summary is qualified in its entirety by a more complete discussion of such risks and uncertainties. In evaluating an investment in our securities, investors should carefully read the risks described below, as well as other risks and uncertainties that we face, which can be found under “—Risk Factors” in this section of this annual report. If any of the following events occur, our business, financial condition, and operating results may be materially adversely affected. In that event, the trading price of our securities could decline, and you could lose all or part of your investment. Such risks include, but are not limited to: 1 Table of Contents Risks Relating To Our Business And The Petrochemical Industry · The cyclical and volatile nature of the petrochemical industry may reduce our net revenue and gross margin, impacting our financial condition. · Adverse conditions in the petrochemical industry may adversely affect demand for our products. · We face competition from suppliers of polyethylene, polypropylene, PVC, and other products. · We may face competition from producers of substitutes for our products as a result of evolving technology, consumer and industry trends and preferences, and regulatory changes. · Our revenue from certain of our customers may be significant, and the credit risks associated with customers could adversely affect the results of our operations and increase expected credit losses. · Higher raw materials costs would increase our cost of products sold and may reduce our gross margin and negatively affect our overall financial performance. · We rely on limited or sole-source suppliers for our raw materials, inputs, and energy, including transportation thereof. · We do not hedge against price changes in our raw materials and, as a result, we are exposed to such fluctuations. · We depend on Petrobras to supply us with a substantial portion of our feedstocks such as naphtha, ethane, propane, refinery off gas and propylene needs, and on logistics services. · We depend on propylene and ethylene supplied by third parties in the United States and Europe. Risks Relating To Global Macroeconomics Factors · Global macroeconomic factors have had, and may continue to have, adverse effects on the margins that we realize on our products. · We may be affected by instability in the global economy and by financial turmoil, including as a result of military conflicts such as those between the United States, Israel and Iran, Russia and Ukraine, and other conflicts in the Middle East. Risks Relating To Our Operations · Our polyolefins and vinyls units in Brazil depend on our chemicals operations to supply them with their ethylene and propylene requirements. In addition, our Brazilian plants depend on certain providers of utilities, including environmental services for the treatment of effluents, industrial waste and water supply for industrial use. · We may be materially adversely affected if there is an imbalance in global logistics, which may cause disruptions to our transport, storage and distribution operations, negatively impacting the costs related thereto. · We rely on access to third-party licensed technology and related intellectual property, and if such rights cease to be available to us on commercially reasonable terms, or at all, or if any such third party ceases to provide us with technical support under license or technical services agreements, certain of our production plants, our operating results and financial condition could be adversely affected. · Capital projects can take many years to complete, and market conditions could deteriorate significantly between the project approval date and the project startup date, negatively impacting project returns and the implementation of our growth strategy. If we are unable to complete projects and investments at their expected cost and in a timely manner, or if the market conditions assumed as a basis for our project economics deteriorate, our business, financial condition, results of operations and cash flows could be materially and adversely affected. 2 Table of Contents · Our insurance coverage may be ineffective, either due to the lack of coverage for any claim, or due to insufficient coverage limits in the event of damage. · Under our growth strategy, we may pursue strategic acquisitions, investments and investments in new businesses. The failure of an acquisition, investment or investments in new businesses to produce the anticipated results, or the inability to integrate an acquired company, could adversely affect our business financial condition and results of operations · Labor strikes may materially and adversely affect our operations. Risks Relating To Health, Safety And Environmental Aspects · Our business and operations are inherently subject to environmental, health and safety risks. As a result, our business is also subject to several stringent regulations, including environmental regulations. · Natural disasters, severe weather and climate conditions, or health epidemics could have a material adverse effect on our overall business. · Climate change may negatively affect our business, financial condition, results of operations and cash flow. · Climate change-related risks and uncertainties, legal or regulatory responses to climate change and failure to meet our sustainable development objectives could negatively impact our results of operations, financial condition or reputation. Risks Relating To Our Shareholders · Some of our shareholders may have the ability to determine the outcome of corporate actions or decisions, which could affect the holders of our class A preferred shares and the ADSs. · We may be subject to attempts to acquire our control, which may lead to significant changes in management, the strategies that we are currently pursuing, or in our current corporate governance practices. · We may face conflicts of interest in transactions with related parties. · If we are unable to comply with the restrictions, covenants or guarantees in the agreements governing our, or certain subsidiaries, indebtedness and liabilities, there could be a default under the terms of these agreements, which could result in an acceleration of payment of funds that we have borrowed or guaranteed and could affect our ability to make principal and interest payments on our debt and liabilities obligations. · There can be no assurance that Novonor will remain our controlling shareholder. Novonor and Petrobras may enter into transactions or other arrangements that may result in us not having a controlling shareholder. If no single shareholder or group of shareholders holds more than 50% of our voting stock or exercise a controlling interest, there may be increased opportunity for alliances between shareholders and conflicts between them. · We lost the right of preference set forth in the current shareholders’ agreement with respect to new business opportunities in the petrochemical sector, and as result, Petrobras, which is our largest supplier of raw materials in Brazil, will be able to invest in the petrochemical sector independently from us and without first giving us a preference to do so. Risks Relating To Legal And Regulatory Matters · Adjustments in tariffs on imports that compete with our products could cause us to lower our prices. · Changes in U.S. and global trade policies and other factors beyond our control may adversely impact our business, financial condition and results of operations. 3 Table of Contents · New Tariffs Imposed or Threatened by the United States Could Result in Increased Costs. · Failure to comply with export control or economic sanctions laws and regulations could have a material adverse impact on our results of operations, financial condition and reputation. · We may not be able to specify in details technical specifications required by our customers’ or updated mechanisms to promptly attend regulatory requirements, and we could be subject to damages based on claims brought against us or our customers as a result of the failure of our products specification. · We may not be able to obtain or renew all licenses, permits and authorizations necessary for conducting our business. · We could be materially adversely affected by the impacts of the Global Settlement. · Unfavorable outcomes in pending or future litigation may reduce our liquidity and negatively affect our financial performance and financial condition. · We could be materially affected by violations of the FCPA, the Brazilian Anti Corruption Law and similar anti-corruption laws. · We are exposed to behaviors of our employees, non-employees and third parties that may be incompatible with our ethics and compliance standards, and failure to timely prevent, detect or remedy any such behavior and/or process vulnerabilities may have a material adverse effect on our results of operations and financial condition. · Unauthorized disclosure or loss of intellectual property, sensitive confidential or personal information, or disruption to information technology systems by cyberattacks or other security breaches, as well as our failure to comply with data protection laws and information security requirements may subject us to significant penalties or liability and may adversely impact our operations, reputation, and financial results. · We are subject to audit by the tax authorities in the jurisdictions in which we operate, which may adversely affect our operating results and financial condition. · Changes in tax laws may result in increases in certain direct and indirect taxes, which could reduce our gross margin and negatively affect our overall financial performance. Risks Relating To Brazil · Brazilian political, economic and business conditions, and the Brazilian government’s economic and other policies, may negatively affect demand for our products as well as our net revenue and overall financial performance. · Changes in industrial policy and related actions undertaken by the Brazilian government and local state governments in Brazil may negatively affect demand for our products as well as our net revenue and overall financial performance. · Fluctuations in the real/U.S. dollar exchange rate could increase inflation in Brazil, raise the cost of servicing our foreign currency-denominated debt and negatively affect our overall financial performance. · The Brazilian government’s actions to combat inflation may contribute significantly to economic uncertainty in Brazil and reduce demand for our products. · Fluctuations or changes in, or the replacement of, interest rates could impact the cost of servicing our debt or reduce our financial revenue, affecting our financial performance. · Brazilian government exchange control policies could increase the cost of servicing our foreign currency-denominated debt, adversely affect our ability to make payments under our foreign currency-denominated debt obligations and impair our liquidity. Risks Relating To Mexico · Political conditions in Mexico may affect actions or decisions by the Mexican government, including Pemex, Cenagas, CFE and CENACE, which are, respectively, Braskem Idesa’s main suppliers of ethane, a provider of natural gas transportation services, an electricity back-up supplier, and the controller of national grid and dispatches of energy power generators, all of which are Mexican state-owned enterprises or governmental entities subject to political interference and related risks. 4 Table of Contents · Mexico has experienced adverse economic conditions, which may adversely affect our business. · A renegotiation of commercial treaties or changes in foreign policy among Mexico, Canada and the United States may negatively affect our business, financial condition, results of operations and prospects. · Political events in Mexico could affect the Mexican economic policy and our business, financial condition and results of operations. · We depend on ethane supplied by Pemex in Mexico. · We depend on services and products supplied by a Mexican state-owned company. · We may face unforeseen challenges in the operation of our Mexico Complex, which could result in this business unit failing to provide expected benefits to us. · We source part of our ethane feedstock from Pemex in Mexico, which we expect to be our primary main source of ethane until the Ethane Import Terminal is operational. · We may be unable to operate the Mexican Complex at full capacity or at all if one or more of our sources of ethane is disrupted. · We depend on regulatory authorizations to import ethane for our production activities in México. · The development of the Ethane Import Terminal may not be successful and may not commence operation as scheduled, be completed within budget or operate at expected levels, which could have a material adverse effect on our businesses, financial condition, cash flows, results of operations and/or prospects. Risks Relating To Our Equity and Debt Securities · Our financial statements as of and for the year ended December 31, 2025 contains a footnote related to a substantial doubt about our ability to continue as going concern, due to increasing pressure on liquidity · The Company is currently assessing alternatives to optimize its capital structure, and the outcome of this process, including any potential restructuring or creditor protection measures, is uncertain and is expected to adversely affect the Company and its stakeholders. · All of the shares issued by Braskem and owned by NSP Inv. are secured for the benefit of certain secured creditors of the Novonor Group. · Holders of our class A preferred shares or the ADSs may not receive any dividends or interest on shareholders’ equity. · Our class A preferred shares and the ADSs have limited voting rights and are not entitled to vote to approve corporate transactions, including mergers or consolidations of our Company with other companies, or the declaration of dividends. · Holders of the ADSs may find it difficult to exercise even their limited voting rights at our shareholders’ meetings. · If holders of the ADSs exchange them for class A preferred shares, they may risk temporarily losing, or being limited in, the ability to remit foreign currency abroad and certain Brazilian tax advantages. · Restrictions on the movement of capital out of Brazil may impair the ability of holders of our shares, ADSs and debt securities to receive payments on their respective obligations or guarantees and may restrict our ability to make payments in U.S. dollars. · The foreign exchange policy of Brazil may affect the ability of Braskem to make money remittances outside Brazil in respect of our equity securities or debt securities. · Holders of the ADSs may face difficulties in protecting their interests because we are subject to different corporate rules and regulations as a Brazilian company and our shareholders may have fewer and less well-defined rights than under the laws of other jurisdictions, including in a jurisdiction in the United States. · Holders of the ADSs may face difficulties in serving process on or enforcing judgments against us and other persons. · Judgments of Brazilian courts enforcing Braskem’s obligations under our equity securities, debt securities or related guarantees would be payable only in reais. 5 Table of Contents · Actual or anticipated sales of a substantial number of class A preferred shares could decrease the market prices of our class A preferred shares and the ADSs. · Holders of the ADSs or class A preferred shares in the United States may not be entitled to the same preemptive rights as Brazilian shareholders have, pursuant to Brazilian legislation, in the subscription of shares resulting from capital increases made by us. · Brazilian tax laws may have an adverse impact on the taxes applicable to the disposition of our ADSs and preferred shares. · The relative volatility and liquidity of the Brazilian securities markets may adversely affect holders of our class A preferred shares and ADSs. · Economic developments and investor perceptions of risk in other countries, including both in developed or emerging market economies, may adversely affect the trading price of Brazilian securities, including our common shares and ADSs, as well as any outstanding debt securities. · We rely on cash generated from operations and external sources to fund our ongoing capital needs. Our level of indebtedness and cash consumption could adversely affect our liquidity position and ability to raise additional capital to fund our operations, limit our ability to react to changes to general market and economic conditions and changes in our industry, and prevent us from meeting our obligations under our agreements (including financing agreements). · Any downgrade in the ratings of Brazil, our Company or our debt securities would likely result in increased interest and other financial expenses related to our borrowings and debt securities that could reduce our liquidity. · Because Braskem Netherlands Finance B.V. and Braskem America Finance Company have no operations of their own, holders of our outstanding debt securities issued by Braskem Netherlands Finance B.V. or Braskem America Finance Company depend on Braskem to provide Braskem Netherlands • Finance B.V., respectively, with sufficient funds to make payments on these debt securities when they become due. · Payments on Braskem’s guarantees are junior to Braskem’s secured debt obligations and effectively junior to the debt obligations of Braskem’s subsidiaries and jointly controlled companies. · Braskem’s obligations under the guarantees of the outstanding debt securities are subordinated to certain statutory preferences. · Brazilian insolvency laws may be less favorable to holders of our shares, ADSs, and outstanding debt securities than bankruptcy and insolvency laws in other jurisdictions. · Braskem Idesa is currently assessing alternatives to optimize its capital structure, and the outcome of this process, including any potential restructuring or creditor protection measures, is uncertain and is likely adversely affect the Company and its stakeholders. There is substantial doubt as to the ability of Braskem Idesa to continue as going concern. Risk Factors Risks Relating To Our Business And The Petrochemical Industry The cyclical and volatile nature of the petrochemical industry may reduce our net revenue and gross margin, impacting our financial condition. The petrochemical industry, including the global markets in which we compete, is cyclical and sensitive to changes in global supply and demand. Our future operating results are expected to continue to be affected by this cyclicality and volatility. This cyclicality may reduce our net revenue, increase our costs, and decrease our gross margin, including as follows: · downturns in general business and global economic activity may cause demand for our products to decline; 6 Table of Contents · when global demand falls, the industry may face competitive pressures to lower its prices, and so may we; · changes in energy prices and other worldwide economic conditions can cause volatility that lead to increases in prices of the raw materials we use, including naphtha, ethane, ethanol and propylene, resulting in significant fluctuations in profits and cash flow from period to period and over business cycles; and · if we decide to expand our plants or construct new plants, we may do so based on an estimate of future demand that may never materialize or may materialize at levels lower than we predicted. Historically, the international petrochemical markets have experienced alternating periods of limited supply, which have caused prices and profit margins to increase, followed by expansion of production capacity worldwide, which has resulted in oversupply and reduced prices and profit margins. Prices in the petrochemical industry follow the global petrochemical industry, and we establish the prices for the products we sell in Brazil, other countries in Latin America, the United States, Europe, and the world with reference to international market prices. Therefore, our net revenue, feedstock costs, and gross margin are linked to global industry conditions that we cannot control, and which may adversely affect our results of operations and cash flow. As disclosed by the Company in the material fact notice dated September 26, 2025, the Company engaged specialized financial and legal advisors to assist in preparing a comprehensive assessment of economic and financial alternatives to optimize its capital structure. Such assessment is still ongoing, and the Company and its advisors have been making structured progress in the formulation of a comprehensive plan to restructure its capital structure, as well as in negotiations with the creditors’ advisors, as reported in its financial statements for the fiscal year ended 2025, included in this annual report. In the course of the work related to such assessment, the Company and its advisors are considering different alternatives, including potential creditor protection measures. Notwithstanding, we clarify that, as of this date, there is no decision regarding which alternative (or set of alternatives) to be implemented. Moreover, relevant events or changes in the cycle and in the petrochemical industry, including initiatives to pursue self-sufficient production targets such as in China, technological innovations, and regulatory changes including related to climate change, may materially affect the future profitability of our business and consequently reduce the recoverable value of our assets, which is reviewed by the annual impairment test, which may adversely affect the profit attributable to our shareholders. Adverse conditions in the petrochemical industry may adversely affect demand for our products. Sales of our petrochemical and chemical products are tied to global production levels and demand, which can be affected by macro-economic factors such as interest rates, international oil prices, energy prices, shifts to alternative products, consumer confidence, employment trends, regulatory and legislative oversight requirements, trade agreements, regulatory developments including related to climate change, as well as regional disruptions, armed conflicts, natural disasters, epidemics, pandemics, or other global events. Therefore, our net revenue, feedstock costs, and gross margin are linked to global conditions that we cannot control, and which may adversely affect our results of operations and financial position. For example, the persistence of the geopolitical conflicts, such as the war in Iran, which is currently impacting the Strait of Hormuz, the conflict involving Russia and Ukraine, the conflicts involving Hamas, Israel and Hezbollah, and other conflicts in the Middle East (including economic sanctions and other regulations imposed by the United States and other international countries as a result thereof) could negatively impact supply chains worldwide and demand for our products and the raw materials we use. Should the conflict in Iran or other international locations further escalate, it is difficult to anticipate the extent to which the consequences of such conflict, including without limitation effects on the price of oil and current or future sanctions, could increase our costs, disrupt our supplies including feedstock, reduce our sales, or otherwise affect our operations. 7 Table of Contents We face competition from suppliers of polyethylene, polypropylene, PVC, and other products. We face strong competition across all of our products. Some of our foreign competitors are substantially larger and have greater financial, manufacturing, technological, competitive feedstock and/or marketing resources than us. Our U.S. operations face competition in the United States from other North American suppliers that serve the North American market. Our European operations face competition in Europe and the other export markets that it serves from European and other foreign suppliers of polypropylene more competitive than us. Our Mexico operations face competition from Mexican and U.S. producers of polyethylene. Competitors from South America may export to Brazil with reduced or no import duties, including through the Manaus Free Trade Zone (Zona Franca de Manaus) and competitors from North America may export to Brazil with reduced taxes or no import duties through the Manaus Free Trade Zone (Zona Franca de Manaus). In addition, suppliers of almost all continents have regular or specific sales to trading companies and direct customers in Brazil for our products, including resins. We generally follow the international markets with respect to the prices for our products sold in Brazil. The domestic price is determined by the import parity, which is based on converters’ imports into Brazil and typically represents spot market price, including but not limited to exchange rate fluctuations and import tariffs that the Brazilian government uses to implement economic policies. Adjustments of tariffs could lead to increased competition from imports, causing us to lower our domestic prices and impact the demand for our products, which would likely result in lower net revenue and could negatively affect our overall financial performance. This combined effect would have a negative impact on our gross margins and overall financial performance. We have no control over the import tax rate policy in Brazil or Mercosur (the Southern Common Market, or Mercosur in Spanish), a common market that serves as a regional integration process and was initially established by Argentina, Brazil, Paraguay, and Uruguay, and subsequently joined by Venezuela and Bolivia. Petrochemical import taxes that are currently in place have changed in the past and may change in the future, including as a result of decisions of the Brazil government or Mercosur. We generally set the prices for our products exported from Brazil based on international market prices. We set the prices for products sold in the United States and Europe based on market pricing in such regions. The price for polyethylene in Mexico is based on prices in the U.S. Gulf Coast region. As a result of the fractioned gas-based ethylene and polyethylene capacities and of the new capacities for the production of resins and petrochemicals, coupled with the competitive pricing of feedstock for petrochemicals production such as ethane, we anticipate that we have been experiencing increased competition from producers of thermoplastic resins, especially from North American, Middle Eastern, and Chinese producers, in the markets in which we sell our products. In addition, the Chinese government has exercised, and continues to exercise, significant influence over the Chinese economy, including governmental actions to incentivize and achieve self-sufficiency production in some specific chains, such as PE and PP. Those new capacities have led to a relevant rebalancing of global export flows and an increase in global competition from our competitors, some of which are larger and have greater competitive advantages than us. In addition, exchange rate variations may affect the competitiveness dynamics in different regions in which we operate. For instance, the appreciation of the real against the U.S. dollar may increase the competitiveness of imported products, which may increase the competition from resins producers in Brazil. Also, (i) the appreciation of the Euro against the U.S. dollar may increase the competitiveness of imported products and, as a consequence, increase competition from imports, and (ii) the appreciation of the Mexican peso against the U.S. dollar may increase the competition from other resins producers in Mexico. We may face competition from producers of substitutes for our products as a result of evolving technology, consumer and industry trends and preferences, and regulatory changes. We compete in a market that relies on technological innovation and the ability to adapt to evolving consumer and global industry trends and preferences. Petrochemical products and other products produced with our petrochemical products, such as consumer plastic items, are subject to changing consumer and industry trends, demands, and preferences, as well as stringent and constantly evolving regulatory and environmental requirements. Therefore, products once favored may, over time, become disfavored by consumers or industries or no longer be perceived as the best option, which may, therefore, affect our results of operations and financial position. 8 Table of Contents Plastic waste and climate change are global environmental concerns that receive growing attention from society in general, national and local governments, private companies, trendsetters, and consumers worldwide. There has been a growing trend to attempt to move away from the use of plastic products, which has been backed by governmental and lawmaking initiatives. In 2019, the European Union approved regulations banning as of 2021 single-use plastic items such as plates, cutlery, straws, and cotton bud sticks and adopting a strategy for the disposal of plastic products in a circular economy that aims to increase recycling significantly and targets the plastic products most often found on beaches and in seas. The European Union is now currently revising such rules to increase recycling and recycled content targets, as well as to establish new regulations on the design and labeling of plastic products. In addition, state and local governments in other countries, for example in China and in Brazil, have also proposed or implemented bans on single-use plastic products. Regarding regulatory issues related to plastic for single use in Brazil, proposed regulations are being discussed at the federal, state, and municipal levels. Additionally, legislative proposals on carbon border adjustment mechanisms aiming at preventing carbon leakage have been under discussion in several countries. So far, none of the proposals have yet affected chemicals and plastic resins, but this might change in the future. Also, new competitors may develop new technologies to offer less carbon-intensive products, which could result in a loss of our competitiveness and a reduction of our revenues. In addition, regulations may be amended or enacted in the future that could make it more difficult to appeal to our customers, end consumers, or market the products that we produce. For example, failure to comply with applicable policies could lead to lower demand for our products, banning of plastic products without allowing the search for alternatives employing efficient solutions, including resins produced by us, could have a material adverse effect on our business, results of operations and financial condition. Also, even if we are able to continue promoting our products, there can be no assurance that our competitors, including producers of substitutes, will not be successful in persuading consumers of our products to switch to their products. Some of our competitors may have greater access to financial or other resources than we do, which may better position them to react and adapt to evolving trends, preferences, and regulatory changes. Any loss of interest in our products or consumer products produced with our products may have a material adverse effect on our business, results of operations, and financial condition. Our revenue from certain of our customers may be significant, and the credit risks associated with customers could adversely affect the results of our operations and increase expected credit losses. We engage in several transactions where counterparty credit risk is a relevant factor, including transactions with certain of our customers. These risks are dependent upon market conditions and also the real and perceived viability of the counterparty. The failure or perceived weakness of any of our counterparties has the potential to expose us to risk of loss in certain situations. Our revenue from certain of our customers may be significant, and the credit risks associated with these customers could adversely affect our results of operations. Additionally, if the viability of the business of certain of our customers deteriorates, these customers seek bankruptcy protection, or our credit policies are ineffective in reducing our exposure to credit risk relating to such customers, our ability to collect our receivables may be adversely affected, and additional increases in expected credit losses accounts may be necessary, which could have a material adverse effect on the results of operations and our cash flows. We record expected credit losses in an amount we consider sufficient to cover estimated losses on the realization of our trade accounts receivable, considering our loss experience and the average aging of our accounts receivable, but we cannot assure you that these amounts will be sufficient to cover eventual losses. In addition, delays in payment cycles by customers may adversely affect our liquidity including the ability to obtain financing for working capital, such as sales of receivables. 9 Table of Contents Higher raw materials costs would increase our cost of products sold and may reduce our gross margin and negatively affect our overall financial performance. Naphtha, propylene, ethane, condensate, refinery off gas, and propane are the main raw materials used in our operations. For the year ended December 31, 2025, these raw materials accounted for an aggregate of 61% of our consolidated cost of products sold. Comparatively, they represented 63% in 2024. Naphtha, a crude oil derivative, is the principal raw material in Brazil that we use to produce our chemical and petrochemical products in Bahia, São Paulo and Rio Grande do Sul, and represents the principal production and operating cost in the region. In addition, ethane and propane are the principal raw materials that we use to produce our chemical and petrochemical products in our petrochemical complex located in Duque de Caxias, in the State of Rio de Janeiro, or the Rio de Janeiro Complex, and represent the principal production and operating cost of such complex. Propylene is the principal raw material that we use to produce polypropylene in the United States and Europe and represents the principal production and operating cost of our United States and Europe Segment. We also purchase propylene in the Brazilian market for certain of our Brazilian polypropylene plants. Ethane is the principal raw material that we use to produce ethylene in the Braskem Idesa’s industrial site (“Mexico Complex”) and represents its principal production and operating costs. In Brazil, we purchase naphtha at prices based on the Amsterdam-Rotterdam-Antwerp naphtha price, or the ARA price, and ethane and propane based on Henry Hub gas and Mont Belvieu propane reference price. We purchase ethane used by our Mexico Segment at prices based on Mont Belvieu ethane reference price. We purchase the propylene used in Brazil based on the international reference prices and in United States plants at prices based on the U.S. Gulf (“USG”) reference prices. We purchase the propylene used in our European plants as reported by international references based on the monthly contract price for propylene for Europe. We purchase refinery off gas used in the São Paulo petrochemical complex at a price related to imported natural gas price. The ARA price of naphtha fluctuates primarily based on Brent crude oil but also follows the markets of fuels and petrochemicals. The price of naphtha, condensate, ethane, propane, and propylene in the international market has been, and may continue to be, volatile. In addition, fluctuations in the U.S. dollar in the future may effectively increase our naphtha, ethane, propane, and propylene costs in reais. Any increase in naphtha, ethane, propane, or propylene costs would reduce our gross margin and negatively affect our overall financial performance to the extent we are unable to pass on these increased costs to our customers and could result in reduced sales volumes of our products and cash flows. We rely on limited or sole-source suppliers for our raw materials, inputs, and energy, including transportation thereof. For naphtha supply to Brazil, we rely on several international suppliers for most of the purchases for the crackers in the states of Bahia and Rio Grande do Sul, and we rely on Petrobras for all of the supply for the cracker located in the state of São Paulo, and we rely on Petrobras for a major part of our supply of ethane and propane in the state of Rio de Janeiro. Also, we are subject to substantial risks because of our reliance on these and other limited or sole-source suppliers of raw materials, additives, catalyzers, other inputs, energy, and other utilities, including the following risks: · if a supplier does not provide naphtha, ethane, propane, refinery off gas, propylene, sea salt, other inputs (including natural gas), or energy, as the case may be, that meet our or their specifications in sufficient quantities and with acceptable performance or quality on time or deliver when required, then sales, production, delivery of our products to our customers on a timely manner and revenue from our plants could be adversely affected; 10 Table of Contents · if our relationship with a key supplier changes or is adversely affected, for example, due to competitive pressures (or conflicting interests), we may be unable to obtain naphtha, ethane, propane or propylene, natural gas, or other inputs, as the case may be, on satisfactory financial terms; · if an interruption of supply of naphtha, ethane, propane, refinery off gas, propylene, sea salt, other inputs (including natural gas), or energy, as the case may be, occurs because a supplier changes its technology roadmap, suffers damage to its manufacturing plants, decides to no longer provide those products or services, increases the price of those products or services significantly or imposes reduced delivery allocations on its customers, it could take us a considerable period of time to identify and qualify alternative suppliers; · some of our key suppliers are small companies with limited financial and other resources, and as a result, they may be more likely to experience financial and operational difficulties than larger, well-established companies, which increases the risk that they will be unable to deliver products as needed; · some of our suppliers are state-owned enterprises subject to political interference, including in Mexico; and · if a key supplier is acquired or there is a significant change in business, the production and sales of our systems and services may be delayed or adversely affected, or our development programs may be delayed or may be impossible to complete. Delays in the availability of naphtha, ethane, propane, refinery off gas, propylene, sea salt, other inputs (including natural gas), or energy of acceptable quality, or our inability to obtain such acceptable naphtha, ethane, propane, refinery off gas, propylene, sea salt, other inputs (including natural gas) or energy in the quantities we need or at all, may adversely affect our revenue and results of operations. We do not hedge against price changes in our raw materials and, as a result, we are exposed to such fluctuations. Currently, we do not hedge our exposure to feedstock price changes beyond transit periods when buying cargo from foreign sources. We believe there is a natural hedge in the petrochemical industry dynamic, mainly due to the historical correlation observed between the principal feedstock of a marginal producer in the global market and with higher production costs, such as naphtha, and its final products (PE, PP, PVC, and others). Historically, naphtha price fluctuations show a high correlation with changes in first- and second-generation petrochemical products. Therefore, any hedge solely with respect to naphtha’s price or any other high cost feedstock would break the natural protection, most likely making our results more volatile. As a result, final consumer prices may not reflect feedstock cost fluctuations. We depend on Petrobras to supply us with a substantial portion of our feedstocks such as naphtha, ethane, propane, refinery off gas and propylene needs, and on logistics services. Petrobras is a relevant Brazilian supplier of naphtha for us and our primary supplier of ethane, propane, propylene, and refinery off gas and has historically supplied the ethane, propane, and refinery off gas that we consume in Brazil. We are a party to several propylene contracts with Petrobras refineries, which have historically supplied approximately 40% of our propylene needs to produce polypropylene in Brazil at prices based on international references. As a result of the limited infrastructure in Brazil to allow the importation of propylene in large quantities and substantial costs associated with the storage and transportation of the product, we depend on propylene supplied by Petrobras to operate our PP plants at optimal operational levels. We have five propylene supply agreements with Petrobras that will expire between 2026 and 2029 and one contract for refinery off gas that will expire in 2028. Two propylene agreements have been renewed (RECAP and REDUC), with the new terms starting in 2026 until 2031. As for the other contracts, we cannot assure that these agreements will be renewed and, if renewed, whether we will be able to keep the same terms and conditions currently in force, including with respect to pricing, volume, pipeline and other infrastructure access. We also have the possibility to make spot propylene purchases from Petrobras in order to seize opportunities in the PP market, in case there are positive margins. 11 Table of Contents In December 2025, we entered into new agreements with Petrobras for the supply of petrochemical naphtha to our petrochemical complexes in São Paulo, Bahia and Rio Grande do Sul with prices based on the international Naphtha ARA reference. The contracts establish for a minimum monthly withdrawal volume, with the possibility of negotiating additional volume to those contracted monthly, reaching up to 4.116 million tons in 2026 and reaching up to 4.316 million tons in 2030. The contracts have a five-year term, beginning on January 1, 2026. In addition, to guarantee access to the naphtha logistics system in Rio Grande do Sul, we also renewed the storage agreement with Petrobras until December 2030 at REFAP located in the city of Canoas. Also, the agreement for the storage at TEDUT, located in the city of Osório, was renewed in June 2024 with a term expiring in June 2028. Petrobras controls a substantial portion of the pipeline infrastructure used to transport naphtha across Brazil and is our primary supplier of naphtha, ethane, propane, propylene, and refinery off gas. A failure to renew or extend our existing agreements for the supply of raw materials or pipeline infrastructure use or termination of such agreements with Petrobras could lead to difficulties in accessing Petrobras’ pipeline infrastructure. The alternative would be to access pipeline infrastructure by negotiating with Transpetro and, if necessary, the National Petroleum Agency, or the ANP, which would grant access to the pipeline infrastructure at a cost defined by the ANP. Therefore, our production volumes and net revenue would likely decrease, while our costs and investments would likely increase, and adversely affect our overall financial performance in the event of the occurrence of one or more of the following: · significant damage to Petrobras’ supply infrastructure through which Petrobras and Braskem import naphtha, or to any of the pipelines connecting our plants to Petrobras’ plants, whether as a result of an accident, natural disaster, fire, or otherwise; · termination by Petrobras of the naphtha, ethane, propane, propylene, and refinery off gas supply contracts with us, which provide that Petrobras may terminate the contracts for certain reasons; · considering that Petrobras (and/or its subsidiaries) controls a substantial portion of the logistics infrastructure of our raw material across Brazil and our existing agreements for using its assets and their operation over certain Braskem’s assets, we could also assume that we would face difficulties to import and ensure access of raw material to our crackers in a scenario that these agreements are terminated by Petrobras (and/or its subsidiaries) and therefore with a substantial impact on the infrastructure that we currently access; or · failure to renew or extend our existing agreements for the supply of raw materials or pipeline infrastructure use, considering that Petrobras is conducting a divestment plan of its assets that also includes certain refineries that supply naphtha and propylene to us and some logistic infrastructure assets. If the supply agreements are terminated or not renewed, our production volumes and net revenue would likely decrease, while our costs would likely increase, and adversely affect our overall financial performance. In addition, although regulatory changes have ended Petrobras’ monopoly in the Brazilian naphtha market and have allowed us to import naphtha, any restrictions imposed on the importation of naphtha into Brazil could increase our production costs, which would reduce our gross margin and negatively affect our overall financial performance. 12 Table of Contents We depend on propylene and ethylene supplied by third parties in the United States and Europe. Our reliance on third-party suppliers poses significant risks to our results of operations, business, and prospects. We rely upon third parties to supply our plants with propylene and ethylene. We acquire propylene and ethylene for our polypropylene plants in the United States under long-term supply agreements and through the spot market. As of December 31, 2025, we had 18 propylene supply agreements and two ethylene supply agreements with several suppliers. The pricing formulas for propylene and ethylene under these supply agreements are generally based on market prices. We cannot assure you that these agreements will be renewed and, if renewed, whether we will be able to keep the same terms and conditions currently in force, including with respect to pricing, volume, pipeline, and other infrastructure access. We acquire propylene for our polypropylene plants in Germany under long-term supply agreements that provide approximately 92% of the propylene requirements of these plants. We have two main supply agreements in Germany. The first can be automatically extended for one-year period and the second has a current validity term of 2 years. The price quotation for propylene under these long-term supply agreements are related to the monthly contract price for propylene for Europe, varying their discounts and/or formula rational according to each supplier. We cannot assure you that these agreements will be renewed and, if renewed, whether we will be able to keep the same terms and conditions currently in force, including with respect to pricing, volume, pipeline, and other infrastructure access. Delays in the availability of acceptable quality propylene or our inability to obtain such acceptable propylene in the quantities we need over what has been contracted or at all may adversely affect our revenue and results of operations. Risks Relating To Global Macroeconomics Factors Global macroeconomic factors have had, and may continue to have, adverse effects on the margins that we realize on our products. Our results of operations may be materially affected by adverse conditions in the financial markets and generally depressed economic conditions. Economic downturns globally and in geographic areas or jurisdictions in which we sell our products may substantially reduce demand for our products and result in decreased sales volumes. Recessionary environments, including global inflation, adversely affect our business because demand for our products is reduced and our costs increase. In addition, raw materials and other costs in our business are subject to wide fluctuations depending on market conditions and government policies. These costs are influenced by several factors over which we have little or no control, including, but not limited to, international and national economic conditions, including higher natural gas costs in Europe, regulations, government policies (including those applicable to the pricing policies of Petrobras, which is one of our main suppliers in Brazil), tariff adjustments and global effects of supply and demand, particularly on commodity prices. We cannot assure that the prices of our products may be increased in a timely manner or be sufficient to keep pace with or offset increases in inflation, operation costs and expenses, amortization of investments, and taxes. As a result, we might not be able to pass on the increased costs to our customers, which could decrease our profit margin and result in a material adverse effect on our business, financial condition, and results of operations. Our ability to export to other countries depends on the level of economic growth in those countries and other economic conditions, including prevailing inflation and interest rates. In addition, disruptions in the global balance between supply and demand and logistics constraints may impair our ability to export our products. Prolonged volatility in economic activity in our key export markets, including the United States, South America, Europe, and Asia, could continue to reduce demand for some of our products, which would adversely affect our results of operations. 13 Table of Contents We may be affected by instability in the global economy and by financial turmoil, including as a result of military conflicts such as those between the United States, Israel and Iran, Russia and Ukraine, and other conflicts in the Middle East. Instability in the global markets and in the geopolitical environment in many parts of the world, as well as other disruptions, may continue to put pressure on global economic conditions. Concerns over the recession, inflation, higher interest rates, geopolitical issues, the global financial markets, unstable global credit markets and financial conditions, and the COVID-19 pandemic have led to periods of significant economic instability, declines in consumer confidence and discretionary spending, diminished expectations for the global economy and expectations of slower global economic growth in the future, and increased unemployment rates. In addition, we face several risks associated with international business and are subject to global events beyond our control, including war, public health crises, such as pandemics and epidemics, trade disputes, economic sanctions, trade wars and their collateral impacts, and other international events. Any of these changes could have a material adverse effect on our reputation, business, financial condition, or results of operations. There may be changes to our business if there is instability, disruption or destruction in a significant geographic region, regardless of cause, including war, terrorism, riot, civil insurrection or social unrest; and natural or man-made disasters, including famine, flood, fire, earthquake, storm or disease. Additionally, the military conflict between the United States, Israel and Iran has introduced a new and significant geopolitical and economic risk to global markets. U.S. and Israeli military operations against Iran and subsequent Iranian military action throughout the Persian Gulf have raised serious concern about oil and natural gas markets, particularly in relation to the Strait of Hormuz. Any prolonged disruption to this waterway poses direct risks to global supply chains, energy availability and operating costs across multiple industries. Retaliatory measures, countermeasures, and escalatory actions by Iran, including missile and drone strikes, cyberattacks, disruptions to critical shipping routes and energy infrastructure, could adversely affect the global economy and financial markets, and lead to further instability and reduced liquidity in capital markets, potentially resulting, for example, in difficulties in obtaining additional funds and sources of financing for our operations. Oil prices have already seen significant upward pressure, as well as many other commodities, and economic expectations related to inflation, monetary prices and activity levels are deteriorating, further straining economies already absorbing the lingering effects of prior geopolitical disruptions. It is not possible to predict the length, outcome, or broader consequences of the ongoing military conflict, which could include further sanctions, regional escalation, geopolitical realignment, and adverse effects on macroeconomic conditions, commodity prices, currency exchange rates, and financial markets. Any such event may increase our costs, decrease our revenues or limit our production and sales volume and adversely affect our business, results of operations and financial condition. Geopolitical and economic risks have also increased over the past few years as a result of trade tensions between the United States and China, the conflicts involving Russia and Ukraine, and the conflicts involving Hamas, Israel and Hezbollah, and the United States, Israel and Iran, and the rise of populism as a global political trend. Growing tensions may lead, among others, to a deglobalization of the world economy, an increase in protectionism or barriers to immigration, a general reduction of international trade in goods and services and a reduction in the integration of financial markets, any of which could materially and adversely affect our business, financial condition and results of operations. 14 Table of Contents Risks Relating To Our Operations Our polyolefins and vinyls units in Brazil depend on our chemicals operations to supply them with their ethylene and propylene requirements. In addition, our Brazilian plants depend on certain providers of utilities, including environmental services for the treatment of effluents, industrial waste and water supply for industrial use. Our chemicals operations are the only supplier of ethylene to our vinyls operations, the only supplier of ethylene to the polyethylene plants and the principal supplier of propylene to the polypropylene plants of our operations in Brazil. Additionally, as the cost of storing and transporting ethylene and its derivatives, including butadiene and other chemical products, is significant and there is no adequate infrastructure in Brazil that allows for the storage of large volumes, a relevant reduction in sales of these products may impact the operating rate of our petrochemical crackers, impacting product availability in Brazil, and our overall financial performance would be adversely affected in case of a major disruption of operations in our chemicals facilities. Also, our production volumes of, and net revenue from, our chemicals operations products could decrease, and our overall financial performance would be negatively affected in the event of any significant damage to the plants of our vinyls and polyolefins operations through which ethylene and propylene is consumed. Our Brazil Segment depends on Cetrel S.A. (“Cetrel”) and Água de Camaçari (“DAC”), in both of which Braskem has indirect relevant participation, and Distribuidora de Água Triunfo (“DAT”), Companhia Riograndense de Saneamento (“CORSAN”), Aquapolo Ambiental S.A (“Aquapolo”), Refinaria de Paulínia (“REPLAN”), Refinaria Duque de Caixas (“REDUC”) and Veolia Brasil for services such as: (i) treatment of effluents and industrial waste; (ii) supply of reuse water; (iii) supply of demineralized, clarified and potable water; (iv) management of water reservoirs; and (v) supply of steam. An interruption in the operations of certain providers of utilities may result in the shutdown of all of our plants in Brazil, in addition to increased environmental risks. If such a shutdown were to happen, our production volumes and net revenue from sales from our plants referred to above would decrease, and our financial performance and results of operations would be adversely affected. We may be materially adversely affected if there is an imbalance in global logistics, which may cause disruptions to our transport, storage and distribution operations, negatively impacting the costs related thereto. Our operations are dependent upon uninterrupted transportation, storage, and distribution of our products and raw materials. Transportation, storage, or distribution of our products and raw materials could be partially or completely, temporarily, or permanently shut down as the result of any number of circumstances that are not within our control, such as: · catastrophic events; · strikes or other labor difficulties; · disruption in global supply chains, including container shortages and lack of fuel impacting the logistics in the regions in which we operate; · war and other armed conflicts, such as the conflicts involving Iran, Israel and United Stated, Russia and Ukraine, the conflicts involving Hamas, Israel and Hezbollah, and other conflicts in the Middle East; and · other disruptions in means of transportation. For example, in May 2018, Brazil experienced a national truck drivers’ strike that severely impacted the logistics operations of many companies throughout Brazil, including the delivery of our raw materials, our products, and other goods. In response to such strike, we gradually reduced the utilization rate of our petrochemical complexes in Brazil. We cannot assure, however, that we will be able to act in the same way in potential new strikes or any other disruption in logistics that may arise in the future. Following the strike, Brazil introduced a national freight cost schedule that set forth minimum prices for freight services provided by truck drivers and freight companies countrywide, which had a lasting impact on freight prices in Brazil and led to sustained increased transportation costs in connection with our operations. 15 Table of Contents In addition, due to shipowners’ and market uncertainties with respect to the future propulsion technology adopted by the world’s merchant fleets, we are currently witnessing a lack of investment in the renewal of the world’s merchant fleet. This might lead to a shortage of ships available to us, which could drive our logistic costs higher. Any significant interruption at our distribution facilities, an inability to transport our products to or from these facilities, or to or from our domestic or foreign customers or suppliers, or an increase in transportation costs, for any reason, would materially adversely affect our operations. We rely on access to third-party licensed technology and related intellectual property, and if such rights cease to be available to us on commercially reasonable terms, or at all, or if any such third party ceases to provide us with technical support under license or technical services agreements, certain of our production plants, our operating results and financial condition could be adversely affected. We use technology and intellectual property licensed from third parties in the regular operation of our business, particularly in the operation of certain machinery and equipment required to produce certain of our products such as our first- and second-generation products, and we may continue to rely on access to third-party technology and intellectual property in the future. There can be no assurance that we will be able to continue to obtain or renew any such necessary technology and licenses on acceptable terms, or at all. Failure to obtain or renew the right to use third-party technology or intellectual property on commercially reasonable terms, or to maintain access to satisfactory technical support, could ultimately lead to stoppages in our production processes and preclude us from selling certain products, which could have a material adverse impact on our operating results and financing condition. Additionally, our inability to maintain existing access to third-party technology, licenses, and technical support on commercially reasonable terms, or at all, or to obtain additional technology, licenses or technical support necessary to manufacture current products or develop new ones, could require us to obtain substitute technology or licenses at a greater cost or of lower quality or performance standards, or require us to carry out unscheduled interruptions of our production plants. There can be no assurance that we will be able to replace any such third-party technology, intellectual property or technical support service for any adequate substitute technology, intellectual property, or technical support in a timely manner to avoid any unscheduled interruption of our production processes or plants, or in a cost-efficient manner. Any of these circumstances could harm our business, financial condition, and results of operations. Capital projects can take many years to complete, and market conditions could deteriorate significantly between the project approval date and the project startup date, negatively impacting project returns and the implementation of our growth strategy. If we are unable to complete projects and investments at their expected cost and in a timely manner, or if the market conditions assumed as a basis for our project economics deteriorate, our business, financial condition, results of operations and cash flows could be materially and adversely affected. Delays or cost increases related to investment programs involving engineering, procurement and construction of plants could materially adversely affect our ability to achieve forecasted rates of return and results of operations and financial position. Delays due to required changes or upgrades to our plants could subject us to fines or penalties as well as affect our ability to contract with our customers and supply certain products we produce. Such delays or cost increases may arise as a result of unpredictable factors, many of which are beyond our control, including, but not limited to: · denial of or delay in receiving requisite regulatory approvals or permits; · unplanned increases in the cost of construction materials or labor; 16 Table of Contents · disruptions in transportation of gear or construction materials; · change in the market and regulatory conditions assumed as a basis for our project economics; · adverse weather conditions, natural disasters, epidemics, pandemics or other events (such as equipment malfunctions, explosions, fires or spills) affecting our plants, or those of vendors or suppliers, shortages of sufficiently skilled labor, or labor disagreements resulting in unplanned work stoppages; · non-performance by, or disputes with, vendors, suppliers (including those responsible for transportation of supplies), contractors or subcontractors. Any one or more of these factors could have a significant impact on our ongoing projects; and · lack of funding or difficulty in obtaining resources for investment including cash from our operations or third-party sources. If we are unable to make up the delays associated with such factors or to recover the related costs, or if market conditions change, it could materially and adversely affect our business, financial condition, results of operations, and cash flows, as well as our ability to implement our business strategy. Our insurance coverage may be ineffective, either due to the lack of coverage for any claim, or due to insufficient coverage limits in the event of damage. We maintain property, business interruption, general liability, environmental, construction, marine, credit, and other types of insurance that we believe are appropriate for our business and operations as well as in line with industry practices. However, we are not fully insured against all potential hazards and incidents inherent in our business. Changes in insurance market conditions have caused, and may in the future cause, premiums, and deductibles for certain insurance policies to increase substantially and, in some instances, for certain insurance to become unavailable or available only for reduced amounts of coverage. If we were to incur a significant liability for which we were not fully insured, we might not be able to finance the amount of the uninsured liability on terms acceptable to us or at all and might be obligated to divert a significant portion of our cash flow from normal business operations. Also, in the event of an accident, we are required to undergo a regulatory assessment through which the insurance coverage needs to be confirmed. If coverage is not confirmed, there will be no indemnity to be paid. In addition, adaptation actions, including those related to climate change, could be considered insufficient by insurance companies, and may make it difficult for us to obtain insurance for our business. Also, premiums and deductibles for certain insurance policies could increase substantially and, in some instances, certain insurance coverage could become unavailable or available only in reduced coverage amounts. Under our growth strategy, we may pursue strategic acquisitions, investments and investments in new businesses. The failure of an acquisition, investment or investments in new businesses to produce the anticipated results, or the inability to integrate an acquired company, could adversely affect our business financial condition and results of operations. We have adopted a growth strategy that is based on organic and inorganic growth, including investments and capital expenditures focused on existing and traditional business, bio-based and recycling businesses. Pursuant to such growth strategy, we may from time to time acquire or invest in complementary companies or businesses with a similar or equal focus. Such acquisitions or investments may include businesses that operate in modern, innovative, and ground-breaking fields, all of which may have an increased level of uncertainty and risk, as they often develop or adopt new technologies and initiatives that may not yet have been proven to work as expected and may not have been sufficiently settled or consolidated. Certain of these businesses may also involve greenfield or brownfield operations, which may take longer periods of time to mature, if they ever mature, and also pose increased uncertainties, challenges and risks. 17 Table of Contents In February 2023, we completed the process of acquiring shares and subscribing to new shares issued by Wise Plásticos S.A. (“Wise”), a Brazilian company in the mechanical recycling sector, holding a 61.1% equity interest in Wise. The success of any acquisition or investment pursuant to our growth strategy will also depend on our ability to make accurate assumptions regarding the valuation, operations, growth potential, integration and synergies, technology, international market, and other factors related to that business. We cannot assure you that our acquisitions or investments will produce the results that we expect at the time we enter into, or complete a given transaction. Furthermore, acquisitions may result in difficulties integrating the acquired companies, and may result in the diversion of our management’s attention from other business issues and opportunities. We may not be able to successfully integrate the operations that we acquire, including, but not limited to, their personnel, financial systems, distribution, or operating procedures. If we fail to integrate acquisitions successfully, our business, financial condition and results of operations could suffer. In addition, the expense of integrating any acquired business and their results of operations may adversely affect our results of operations. Certain acquisitions, partnerships, and joint ventures we make may prevent us from competing for certain clients or in certain lines of business and may lead to a loss of clients. We may spend time and money on projects that do not increase our revenue in the foreseeable future or at all, including those investments related to industrial decarbonization and recycling, renewable products, and the circular economy. To the extent we pay the purchase price of any acquisition in cash, it would reduce our cash reserves, and to the extent the purchase price is paid with any of our shares, it could be dilutive to our shareholders. If we pay the purchase price with proceeds from the incurrence of debt, it would increase our level of indebtedness and could negatively affect our liquidity and restrict our operations. Our competitors may be willing or able to pay more than us for acquisitions, which may cause us to lose certain acquisitions that we would otherwise desire to complete. We cannot ensure that any acquisition, partnership or joint venture we make will not have a material adverse effect on our business, financial condition and results of operations. Labor strikes may materially and adversely affect our operations. Labor strikes in our plants and facilities, operated by us or third parties, and in our main suppliers and customers plants and facilities may have a material adverse effect on our financial condition or results of operations. Future labor actions, including strikes, could have a material adverse effect on our financial performance. Risks Relating To Health, Safety And Environmental Aspects Our business and operations are inherently subject to environmental, health and safety risks. As a result, our business is also subject to several stringent regulations, including environmental regulations. As a company operating in the petrochemical industry, our operations, including acquired by us, and operated by us or third parties, including the companies and businesses that we have acquired, involve the generation, use, handling, storage, transportation (mainly by pipeline, road, train, fluvial and maritime), treatment, discharge and disposal of hazardous substances and waste into the environment. Notwithstanding our environmental, health and safety standards, policies and controls, our operations remain subject to incidents or accidents that could adversely affect our business or reputation. Our industry is generally subject to significant risks and hazards, including fire, explosions, toxic gas leaks, contamination of soil and water, spilling of polluting substances or other hazardous materials, smoke or odor emission, failure of operational structures and incidents involving mobile equipment, vehicles or machinery, associated or not with the manufacture of petrochemicals and the storage and transportation of feedstock and petrochemical products. These events may occur due to technical failures, human errors or natural events, among other factors, and could result in significant environmental and social impacts, damage to or destruction of production plants and communities, personal injury, illness or death of employees, contractors or community members close to our operations or close to our logistic routes, terminals and pipelines, environmental damage, delays in production, and, in certain circumstances, liability in civil, labor, criminal and administrative lawsuits, difficulties in obtaining or maintaining operating permits and environmental licenses, and impacts on our reputation, among other consequences. 18 Table of Contents In addition, our operations, operated by us or third parties, could generate impacts to the communities and to the environment, from our regular operations, as well as in the management of the existing environmental liabilities, which may result in environmental, material and human damages, fines and sanctions, including loss of operating license, in addition to damage to our image and reputation, which could have a material adverse effect on our results of operations and financial condition. For example, over 30 years ago, a leak of chemical products occurred from a tank installed on a property owned by the company Companhia Carbonos Coloidais (“CCC”), located in Madre de Deus, in the State of Bahia. These products were the property of the company Tecnor Tecnolumen Química do Nordeste Ltda. (“Tecnor”) and may have been acquired by domestic producers at the time, including by Companhia Petroquímica de Camaçari, a company that subsequently was merged into Braskem. Both CCC and Tecnor are companies that have never had any corporate relations with Braskem and no longer have any operating activities. Given our experience in the chemical and petrochemical industry and related products, the authorities requested our collaboration on the analysis, studies and environmental remediation, with monitoring by local authorities, which has been occurring since 2003. Following the agreement between the City of Madre de Deus, the Public Ministry of the State of Bahia and CCC in 2015, by means of an Amendment to this Term of Commitment, we supported through the implementation of a vacancy program, including about 200 properties, of an area near CCC’s property, declared as public utility by the City Hall in February of 2021, for the safe continuity of the remediation efforts. Our business could be adversely affected by safety or product liability issues. Failure to appropriately manage occupational safety, process safety, product safety, human health, product liability and environmental risks inherent to the chemical and petrochemical businesses and associated with our products, product life cycles and production processes could result in unexpected incidents, including releases, fires, or explosions resulting in personal injury, loss of life, environmental damage, loss of revenue, legal liability, and/or operational disruptions. Public perception of the risks associated with our products and production processes could impact product acceptance and influence the regulatory environment in which we operate. Changes to current applicable laws may impose changes on standards we have already implemented, which can take time to review and update and could require significant capital expenditures. For example, we have concluded or are currently concluding studies related to dams located at certain of our industrial sites as a result of a change in Brazilian law that now requires that all water and waste dams have a safety plan for these structures. Environmental studies that we have commissioned have indicated instances of environmental contamination of the soil and underground water at certain of our plants. If the laws and regulations applicable to risks and safety plans change, we may be required to revise the studies that we have carried out or take further action to rectify potential issues that would not need to be addressed under current laws and regulations. In addition, we and certain of our executive officers have received certain notices related to environmental violations and are or have been subject to investigations or legal proceedings with respect to certain alleged environmental violations. These environmental issues, and any future environmental issues that may arise, could subject us to fines or other civil or criminal penalties imposed by Brazilian authorities. Also, under environmental laws and regulations in the countries in which we operate, we are required to obtain operating licenses and permits for our manufacturing plants. For example, under Brazilian federal and state environmental laws and regulations, if any of our environmental licenses or permits lapse or are not renewed or if we fail to obtain any required environmental licenses or permits or does not to meet the conditions established in the licenses or environmental permits, we may be subject to fines ranging from R$500 to R$50 million, and the Brazilian government may reverse mentioned licenses or permits, partially or totally suspend our activities and impose other civil and criminal sanctions on us, including our managers. 19 Table of Contents Pursuant to Brazilian environmental legislation and regulations, our corporate veil may be pierced to ensure that sufficient financial resources are available to parties seeking compensation for damage caused to the environment. In this sense, officers, shareholders and/or business partners or affiliates may, together with the polluting company, be held liable for damage to the environment. In addition, our production and logistics processes are subject to inherent safety risks, which may lead to injuries, disability or death of our employees or individuals participating in such processes and communities, as well negatively impact the environment. Such risks cannot be entirely eliminated or fully mitigated even with full compliance with all safety measures applicable to us or required by laws or regulations. We may face a negative impact on our image and reputation, and on our business, financial condition and results of operations. Until May 2019, we operated rock salt extraction wells located in Maceió, in the state of Alagoas. The operation was permanently interrupted due to the indication that it would have contributed to the occurrence of relevant subsidence in the region of four districts, with the occurrence of damage to properties and public roads located in the region. Several individual and collective lawsuits were filed in the state of Alagoas in relation to this geological event. To date, we have entered into the agreements described below to terminate three public-interest civil actions or civil public actions (“ACP”) filed by the competent authorities: · ACP Labor settlement: in February 2020, we committed to disbursing R$40 million to fund a Business Recovery and Promotion of Educational Activities Program for residents and workers in the districts of Mutange, Bom Parto, Pinheiro and Bebedouro, in Maceió, state of Alagoas. This agreement has been fulfilled in its entirety; · ACP of Residents settlement: through an Instrument of Agreement to Support the Relocation of People in Risk Areas, ratified by the court in January, 2020 and updated in December, 2020, we committed to supporting the relocation and to compensating residents, business owners and owners of vacated properties located in the risk areas defined in the Civil Defense Map through the Financial Compensation and Support for Relocation Program (Programa de Compensação Financeira e Apoio à Realocação, or “PCF”), by offering proposals for financial compensation and entering into individual agreements ratified by the court on January 6, 2021, which resulted in the termination of ACP of Residents; and · ACP Socio-Environmental settlement: in December, 2020, we committed to (i) adopting the necessary measures to stabilize the cavities and monitor the ground, implementing the measures of the mine closure planning presented to the Brazilian National Mining Agency (Agência Nacional de Mineração, or “ANM”) and subject to its approval; (ii) repairing, mitigating or compensating potential environmental impacts and damages resulting from the mining activities (salt extraction) in the city of Maceió, state of Alagoas, to be defined by an Environmental Diagnosis developed by an expert and independent company approved by the Prosecutor’s Office; (iii) allocating R$1.58 billion to implement measures in the vacated area, actions related to urban mobility and to compensate potential socio-urbanistic impacts and damages, and for social collective moral damages. Following court approval of this agreement, the public civil action seeking socioenvironmental reparation was dismissed. Additionally, we have also entered into three other main agreements with the competent authorities: 20 Table of Contents · Term of Agreement for Implementation of Socioeconomic Measures for the Requalification of the Flexal Area: this agreement, which was ratified in October 2022, establishes the adoption of requalification actions in the Flexais region, compensation to the Municipality of Maceió and indemnities to the residents of this location; · Instrument of Global Agreement with the Municipality of Maceió: this agreement, which was ratified in July, 2023, establishes, among other things: (i) payment of R$1.7 billion as indemnity, compensation and full reimbursement for any property and non-property damages caused to the Municipality of Maceió; and (ii) adhesion of the Municipality of Maceió to the terms of the Socio-environmental Agreement, including the Social Actions Plan (PAS); and · Term of Agreement with the State of Alagoas (“State Agreement”), entered into on November 10, 2025, which establishes, among other matters: (a) a total amount of R$1.2 billion as compensation, indemnification and/or reimbursement to the State of Alagoas for the full reparation of any and all pecuniary and non-patrimonial damages at the state level; and (b) grants the Company full settlement for any damages arising from and/or related to the geological event in Alagoas, including the extinction of the State of Alagoas’ indemnification lawsuit. Of the R$1.2 billion established in the State Agreement, R$139 million (on an updated basis) had already been paid. The remaining balance must be paid in 10 variable annual installments, subject to adjustment, mainly after 2030, considering the Company’s payment capacity. We have been taking the necessary actions for closing and monitoring the salt cavities, environmental actions and other technical matters. Based on the findings of sonar and technical studies, stabilization and monitoring actions were defined for all 35 existing mining fronts and are being reviewed and updated from time to time according to the evolving status of the geological event. The closure plan of 35 salt cavities currently considers the following: (i) 18 cavities have recommendation for priority filling with solid material. To date, 6 cavities have been filled with sand, 4 cavities have reached the technical filling limit, 6 cavities are in the filling process, and 2 cavities are in the preparation and planning activities; (ii) 6 cavities were naturally filled and, therefore, do not indicate, at this moment, the need for additional measures; and (iii) 11 cavities remain within the salt layer and suitable for pressurization. By the end of 2024, the Company based on the technical note issued by expert consultancy, considered the recommendation of filling these pressurized cavities with solid material, in the long term, over the course of several years to decades, and after the completion of the current filling plan, with the purpose of to achieve a maintenance-free state for the 35 cavities, suitable for the final closure of the field. Note that any need for additional actions is assessed on an ongoing basis by us and are based on technical studies prepared by external specialists, whose recommendations may be updated periodically according to the changes in the geological event and knowledge obtained, being submitted to competent authorities and following the execution timeframe agreed under the mine closure plan, which is public and regularly revaluated with ANM. Subsidence is a dynamic process occurring in the area outlined by the priority action lines map issued by Civil Defense of Maceio Municipality and should continue to be monitored during and after the actions envisaged in the closure plan. The results of the monitoring activities will be important to assess the need for potential future actions, with a focus on safety and monitoring of stability in the region. Any potential future actions may result in significant additional costs and expenses that may differ from current estimates and provisions. 21 Table of Contents Regarding environmental initiatives, in compliance with the Agreement for Socio-Environmental Reparation, we continue implementing the actions established in the environmental plan approved by the Federal Prosecution Office (“MPF”) and sharing the results of its actions with the authorities. A review of the environmental diagnosis is planned after the implementation of the ongoing actions. As one of the results of the collapse of cavity 18, occurred in December 2023, as agreed in the Socio-Environmental Reparation Agreement, the specific Environmental Diagnosis to evaluate potential impacts caused by the collapse of said cavity, conducted by specialized technical advisors, was completed. The report was submitted to the authorities Considering the actions for closing and monitoring the salt cavities, environmental actions and other technical matters, we have provisioned as of December 31, 2025 the amount of R$1.7 billion, net of adjustment to present value. There are currently several lawsuits related to the geological event in Alagoas. Below, we describe the current status of the main claims faced by the Company: On February 2, 2021, we were notified of the filing of a lawsuit by Companhia Brasileira de Trens Urbanos (“CBTU”), initially requesting only a preliminary injunction for maintaining the terms of the cooperation agreement previously signed by the parties. The request was denied in the lower and appellate courts, given the fulfillment of the obligations undertaken by us. On February 24, 2021, CBTU filed an amendment to the initial request claiming the payment of compensation for losses and damages in the amount of R$222 million and for moral damages in the amount of R$500 thousand, as well as the imposition of obligations, including the construction of a new rail line to replace the stretch that passed through the risk area. As of December 31, 2025, the amount of this lawsuit was R$1.53 billion. As a result of a joint petition filed by the parties, an agreement was presented by the parties and ratified by the court, and the parties agreed to continue negotiations for a possible conciliation between the parties. On August 26, 2025, CBTU and Braskem entered into a Technical Cooperation Agreement aimed at enabling the road requalification of the railway section whose operations were suspended. After the lawsuit suspension period ended, on September 18, 2025, Braskem submitted its defense, and on October 15, 2025, CBTU filed a reply with its considerations. Our management, supported by the opinion of outside legal counsel, classifies the probability of loss in this lawsuit as possible. In March 2023, we were informed of the claim filed by the State of Alagoas, requesting compensation for alleged damages resulting, among others claims, from the loss of properties within the risk area defined by the Civil Defense of Maceió, alleged investments initiated by the State of Alagoas that were rendered useless due to the evacuation of the risk area and alleged loss of tax revenue, with a request that such damages to be determined by a court appraiser. On October 10, 2023, the trial court issued a summary judgment ordering Braskem to reimburse the amounts invested, public equipment and losses in tax collection as required by the State of Alagoas. The indemnity amounts must be set in the award calculation phase. We filed an appeal against the decision. On November 10, 2025, Braskem and the State of Alagoas entered into a settlement agreement related to the geological event that occurred in Alagoas (the “State Agreement”). The State Agreement provides, among other matters: (a) a total amount of R$1.2 billion as compensation, indemnification and/or reimbursement to the State of Alagoas for the full reparation of any and all pecuniary and non-patrimonial damages at the state level; and (b) grants the Company a full settlement for any damages arising from and/or related to the geological event in Alagoas, including the extinction of this indemnification lawsuit, which in December 2025 has an adjusted amount of R$1.9 billion, with its effects taking place upon judicial ratification. On January 7, 2026, the agreement was judicially approved. The decision is not final and remains subject to appeal. There is a performance bond pledged by us for this lawsuit in the amount of R$1.4 billion. Our management, supported by the opinion of outside legal counsel, classifies the probability of loss in this lawsuit as possible. In March 2023, we also became aware of the Public Civil Action filed by the Public Defender’s Office of the State of Alagoas (“DPE”) against us, the Federal Government, the State of Alagoas and the Municipality of Maceió, which pleads for measures related to the Flexais region, including (i) the registration of residents of this region so that they can opt for relocation through the Company’s Relocation and Financial Compensation Program; and (ii) the claim for compensation in the amount of R$1.7 billion for moral and material damages allegedly owed to residents of this region, with a subsidiary claim for judicial blocking of said amount. The injunction relief requests were rejected by the trial and appellate courts. On January 19, 2024, a decision was rendered judging partially valid the requests made by the DPE. The judge determined, among other directives, to establish the amount of moral damage until the requalification is completed and to ascertain the material damage resulting from the devaluation of properties in the area. It was also determined the development of the case to adjudicate the request for relocation of residents, among others. On August 19, 2025, the appeals of both Braskem and the Federal Government were upheld on their merits, resulting in the reversal of the lower court’s ruling, recognizing the validity of the agreement and therefore reversing the additional indemnification previously imposed. The appeals of the State of Alagoas and the DPE were denied. On October 30, 2025, the Federal Court of Appeals (“TRF5”) unanimously granted Braskem's interlocutory appeal and overturned the lower court's ruling that had ordered an anthropological expert examination. As of December 31, 2025, the amount of this claim was R$345 million. Our management, supported by the opinion of outside legal counsel, classifies the probability of loss in this lawsuit as possible. 22 Table of Contents In August 2023, we were informed of the Public-Interest Civil Action filed by FEPEAL and CNPA (jointly the “Associations”) against the Company, seeking compensation for material damages (damages and loss of profit) and homogeneous individual and collective moral damages for the Associations and each of the alleged 8,493 affected fishermen represented by the Associations. As a preliminary measure, the Associations requested, among other claims, that the Company provision sufficient funds to guarantee the compensation of fishermen included in the public-interest civil action, while publishing a material fact disclosed on Form 6-K on October 6 to the shareholders, requests that were denied by the Court. Among other requests, the Associations claim the payment of: (i) compensation for (a) individual and homogeneous moral damages suffered; (b) material damages in the form of individual and homogeneous loss of profits; (ii) compensation for collective moral damages for the Associations; (iii) compensation for collective material damages to the Associations; and (iv) attorney fees in the amount of 20% on the value of the award. The proceedings were stayed by the TRF5 pending the judgment of the interlocutory appeal filed by Braskem, which alleges the irregularity in the representation of the plaintiff institutions. On November 13, 2025, TRF5 denied Braskem’s interlocutory appeal and Braskem filed motions for clarification against this decision, which remains pending of judgment. As of December 31, 2025, the plaintiffs’ claims amounted to R$2.36 billion, and our management, supported by the opinion of outside legal counsel, classifies the likelihood of loss in the amount of R$1.97 billion as possible and the amount of R$394 million as remote. On November 30, 2023, we were informed of the Public-Interest Civil Action filed by the Federal Prosecution Office, Federal Public Defender’s Office (“DPU’) and Alagoas State Prosecution Office (“MPE”) against the Municipality of Maceió and Braskem, with a request for a injunctive relief based on evidence, against the Municipality of Maceió: (i) the disclosure of the new Map of Priority Action Lines, Version 5, and (ii) preparation of the Action Plan to address issues related to the identification of the roads and public equipment located in the region. Against Braskem, they request through a preliminary injunction: (i) inclusion in the PCF of the new criticality area 00 (area defined by the Civil Defense of Maceió with recommendation of vacancy) of Version 5 of the Civil Defense Map and making feasible the optional inclusion of all residents affected whose properties are located in the criticality area 01 (area defined by the Civil Defense of Maceió with recommendation of monitoring) of Version 5 of the Map, with inflation adjustment corresponding to the amounts adopted by the PCF; (ii) establishment, with the permission of the affected party of the criticality area 01, of a Program for Reparation for Damages to Properties resulting from the alleged depreciation of the property, as well as the alleged pain and suffering resulting from the inclusion of the property in the version 5 of the Map; (iii) engagement of independent and specialized consultants to identify the alleged damage to properties if the affected party decides to remain in the area of criticality 01 of Version 5 of the Civil Defense Map; and (iv) engagement of independent and specialized technical advisory to provide support to the affected parties in the analysis of the scenarios and decision-making of their relocation or staying in the area. On the merits, they request confirmation of the preliminary injunctions. On November 30, 2023, the judge rendered a decision granting the injunctive relief. Such decision granting injunction relief was suspended on January 22, 2024, and formally reversed, on February 27, 2025 by TRF5 on a final decision issued in the interlocutory appeal filed by the Company. In June 2025, the plaintiffs reiterated their request for evidentiary relief, seeking the voluntary relocation of residents from a specific area of the Bom Parto neighborhood. On September 3, 2025, a decision was rendered granting the evidentiary relief and ordering the inclusion, within the PCF, of 13 properties located in a specific area of the Bom Parto neighborhood, which had previously been declared uninhabitable by the Municipal Civil Defense authorities due to other reasons not related to the geological event. On October 10, 2025, following an appeal filed by Braskem, the TRF5 rendered a decision suspending the effects of the decision. As of December 31, 2025, the adjusted amount of this claim was R$1.25 billion. Our management, supported by the opinion of outside legal counsel, classifies the probability of loss in this lawsuit as possible. 23 Table of Contents On December 18, 2023, we were informed of the Action against the Violation of a Constitutional Fundamental Right (ADPF) filed by the Alagoas State Governor before the Federal Supreme Court due to some clauses of the agreements entered into out-of-court and ratified in the records of the cases ACP Reparation for Residents, ACP Social-Environmental Reparation and Flexais Agreement, which deal with the waiver given to the Company, as well as the acquisition and potential exploration of the vacant properties. We presented a statement applying for the denial of the ADPF continuance. On January 10, 2024, the judge rapporteur determined the testimony of Braskem, Municipality of Maceió, State of Alagoas Prosecution Office, Alagoas State Defender’s Office and Federal Public Defender’s Office and the statement of the Office of the Attorney General and Office for the General Counsel for the Federal Government. These interested parties presented their statements, and, on June 24, 2024, the judge rapporteur issued a decision denying the ADPF continuance. The Alagoas State Governor appealed this decision. It is not possible to assign a contingency amount to this lawsuit, which has illiquid claims, aiming at the declaration of nullity of specific contractual clauses of the Agreements. Our management, supported by the opinion of outside legal counsel, classifies the probability of loss in this lawsuit as possible. In March 2024, we were informed of the Public-interest Civil Action filed by DPE against Braskem, seeking, among other requests, the challenge of clause 69 of the Agreement for Socio-environmental Reparation (payment of R$150 million for collective moral damages) alleging that there were facts subsequent to the date of the agreement that would give rise to additional damages. The DPE sustains that: (i) the waiver set forth in the Agreement for Socio-environmental Reparation would not cover future damages; (ii) the transfer of the vacated properties to Braskem would violate constitutional principles; (iii) the damages caused should be fairly compensated; (iv) collective existential damages should be compensated; and (v) Braskem should be condemned for illicit profit, yet to be liquidated. Based on such allegations, it requests, as a preliminary measure: (i) the suspension of clause 58, second paragraph, of the Agreement for Socio-environmental Reparation, in order to rule out the possibility of reversion of the area to the benefit of Braskem; (ii) the imposition of inalienability of the PCF area until the final and unappealable decision on the merits of the claim, considering the need for the assets acquired by the Financial Compensation Program not to be subject to any disposal, nor subject to seizure. On April 12, 2024, these preliminary claims were rejected by the court. On the merits, it requests, among others: (i) the loss of all properties subject to the PCF, with the possibility of reverting the area to the victims or to public domain, in addition to the conviction of Braskem to the payment, as collective and social moral damages, to the same amount spent by Braskem for material damages; (ii) the conviction of Braskem, as existential damages, for the loss of all properties subject to the PCF; (iii) the conviction of Braskem for illicit profit, with the loss of the PCF properties, in addition to the payment of the amounts the Company obtained due to its alleged illicit conduct (to be determined in a liquidation proceeding); and (iv) subpoena to the Investor Relations Officer, for the purposes of regulatory obligations, with publication of a relevant fact. On November 27, 2025, by unanimous decision, the TRF5 granted Braskem’s interlocutory appeal, recognizing the lack of standing of the DPE as well as the validity of the Agreement for Socio-environmental Reparation and the res judicata, resulting in the dismissal of the lawsuit. On January 6, 2026, the DPE submitted a petition requesting that the trial session be declared null and void. On March 17, 2026, a judgment was rendered by the 3rd Federal Court dismissing this Public Civil Action, based on binding precedent set by the TRF5. The decision recognized that relativizing res judicata creates legal uncertainty and discourages amicable settlement and further emphasized the inadmissibility of the claims brought by the Public Defender’s Office due to lack of legal interest, legal impossibility, and unfeasibility. The adjusted value of the claim attributed by the DPE is R$182 million. Our management, supported by the opinion of outside legal counsel, classifies the probability of loss in this lawsuit as possible. 24 Table of Contents In September 2024, we were notified of the filing of a public civil action Public Defender’s Office of the State of Alagoas seeking, among other requests, to review the compensation paid for moral damages in the context of the Financial Compensation and Relocation Support Program, with a request for partial annulment of the signed agreements related to the PCF and approved in court. On July 28, 2025, Braskem filed an appeal against the decision that dismissed its preliminary defenses, which remains pending judgment. On December 10, 2025, the Federal Public Defender’s Office filed a motion seeking its inclusion as a plaintiff to replace the State Public Defender’s Office, based on arguments set forth in the appellate decision issued in the class action lawsuit concerning collective moral damages. The adjusted value of the claim attributed by the plaintiff is R$5.8 billion. Our management, supported by the opinion of outside legal counsel, classifies the probability of loss in this lawsuit as remote. In January 2026, we are informed of the Public Civil Action filed by the Public Defender’s Office of the State of Alagoas and the Association of Entrepreneurs and Victims of Braskem, seeking to hold Braskem liable for damages allegedly suffered by entrepreneurs who conduct economic activities along the boundary of the Civil Defense Map, including Area 01. As a preliminary injunction, the plaintiffs seek the creation of an emergency support fund for entrepreneurs, with an initial contribution of R$400 thousand by Braskem to subsidize loans for the benefit of the entrepreneurs. On the merits, they seek compensation for actual damages (including real estate devaluation, loss of improvements, and other property losses), loss of profits, loss of business goodwill, individual and collective moral damages, existential damages, and social damages. The plaintiffs assigned a value of R$2 billion to the claim. Our management, supported by the opinion of outside legal counsel, classifies the probability of loss in this lawsuit as possible. For additional information on the main lawsuits, see “Item Financial Information—Legal Proceedings—Civil Proceedings—Alagoas—Mining Activities.” As of December 31, 2025, the total outstanding provision related to the geological event in Alagoas was R$3.5 billion, which was based on current estimates and assumptions and may be updated in the future due to new facts and circumstances, including, but not limited to: changes in the execution time, scope, method and the success of action plans, new repercussions or developments arising from the geological event, including possible revisions of the Civil Defense Map, studies that indicate recommendations from specialists, including the Technical Monitoring Committee, according to the Agreement for Compensation of Residents; and other new developments related in the matter. The actions to repair, mitigate or offset potential environmental impacts and damages, as provided for in the Socio-Environmental Reparation Agreement, are in progress and eventually new measures may be necessary and will be consolidated as part of the measures for a Plan to Recover Degraded Areas (“PRAD”). We have been making progress in negotiations with private and public entities about other indemnification requests to understand them better, which may lead to future agreements. Although future disbursements may occur as a result of said negotiations, as of the date of this annual report, we are unable to predict the results and timeframe for concluding these negotiations or their possible scope, and the total associated costs in addition to those already provisioned for. It is not possible to anticipate all of the new claims related to damages or other nature that may be brought by individuals or groups, including public or private entities, that understand they suffered impacts or damages somehow related to the geological event and the relocation of people from risk areas, as well as new notices of violation or administrative penalties of diverse nature. We continue to face and could still face administrative procedures and various lawsuits filed by individuals or legal entities not included in the PCF or that disagree with the financial compensation offer for individual settlement, as well as new collective actions and new lawsuits filed by public utilities concessionaires, entities of the direct or indirect administration of the State of Alagoas, the Municipality of Maceió or the Brazilian federal government. Therefore, the number of such actions or lawsuits, their nature or the amounts involved cannot be estimated at this moment. Consequently, we cannot eliminate the possibility of future developments related to all aspects of the geological event in Alagoas, the relocation process and actions in vacated and adjacent areas, so the expenses to be incurred may significantly differ from its estimates and provisions. 25 Table of Contents Natural disasters, severe weather and climate conditions, or health epidemics could have a material adverse effect on our overall business. We are subject to increasing climate-related risks and uncertainties, many of which are outside of our control. Climate change may result in more frequent severe weather events, potential changes in precipitation patterns and extreme variability in weather patterns which can disrupt our operations as well as those of our customers, partners and suppliers. Some of our plants are located in places that could be affected by natural disasters, such as floods, earthquakes, hurricanes, tornados and other natural disasters, which could disrupt our operations, operated by us or third parties, or the operations of our customers or suppliers and could damage or destroy infrastructure necessary to transport our products as part of the supply chain. Additionally, other unanticipated problems such as health epidemics or pandemics, could also cause operational disruptions of varied duration. Such events could require maintenance shutdowns, delay shipments of products or supplies or result in costly repairs, replacements or other costs, which could have a material adverse effect on our financial performance. Brazilian power generation capacity is mainly based on hydroelectric facilities. If the amount of water available to energy producers becomes scarce due to drought or diversion for other uses, the cost of energy may increase due to burdens and additional costs to guarantee the operation of the system, which could lead to price increases in long-term price contracts. The reliability of energy production can also be impacted, leading to an increase of the risk of interruptions and shutdowns at our plants. In addition, if the amount of water available to industrial plants becomes scarce, there may be a need to reduce production at the affected sites. Such conditions could have a material adverse effect on our sales and margins. Climate change may negatively affect our business, financial condition, results of operations and cash flow. A considerable number of experts, international organizations, regulators and other analysts argue that global climate change has contributed, and will continue to contribute, to the increase in the unpredictability, frequency and severity of natural disasters (among but not limited to hurricanes, droughts, tornadoes, freezes, other storms and fires) in some parts of the world. As a result, several legal and regulatory measures, in addition to social measures, have been and will be established in several countries to reduce carbon and other GHG emissions and combat climate change globally. Such reductions in GHG emissions are expected to lead to an increase in energy, transport and input costs, in addition to requiring us to make additional investments in facilities and equipment. It is not possible to predict the impact of global climate change, if any, or legal, regulatory and social measures in response to climate change concerns, and whether such factors could negatively affect the business, financial condition, results of operations and operating cash flows. Also, several countries are evaluating and seeking to implement carbon pricing policies for carbon emitting companies that are producers in these countries or that export products to these countries. If this occurs, our costs may be negatively impacted as we, as a petrochemical company, have a material carbon footprint. International market restrictions or taxation on products imported from countries with insufficient climate policies could lead to a loss of our global competitiveness and reduce our revenues. Since 2008, we account for the emissions of our operations and publish the results in a GHG inventory, which currently follows the operational control approach, contemplating our global emissions of scopes 1, 2, and 3, and which is annually verified by an independent third party. In 2025, Braskem recorded 9.4 million tons in carbon emissions and any carbon tax mechanism could negatively affect our business, financial condition, results of operations and operating cash flows. For example, The European Commission has published in 2021 its “Fit for 55 Package” climate package, which includes extensive policy towards tougher emissions targets including the carbon border adjustment mechanism (CBAM) as holding wide ranging implications for the export industry into Europe. Laws and regulations that seek to reduce GHG are being defined in some regions and may be defined globally in the future, which could have a material adverse impact on our operating results, cash flows and financial condition. One of the possible effects of the increase in requirements related to the reduction of GHG emissions is the increase in costs, mainly due to the demand for the reduction of fossil fuel consumption and the implementation of new technologies in the production chain. Removing subsidies or levying taxes on fossil energy sources could increase fuel prices for large consumers and thus production costs. Levying taxes on carbon-intensive suppliers could increase associated production costs. Taxation on carbon intensive suppliers could increase production costs that could negatively affect our business, financial condition, results of operations and operating cash flows. Additionally, the difficulty of adapting to climate change and reducing the emission of GHG in production processes and the value chain could negatively affect our business, financial condition, results of operations and cash flows. 26 Table of Contents Climate change-related risks and uncertainties, legal or regulatory responses to climate change and failure to meet our sustainable development objectives could negatively impact our results of operations, financial condition or reputation. In 2020, we announced long term sustainable development objectives, including (i) to reach in 2030 an absolute 15% reduction in greenhouse gas emissions (GHG) in scopes 1 and 2 – in relation to the average of the years 2018, 2019, and 2020 – and to achieve carbon neutrality by 2050 in scopes 1 and 2 and (ii) to expand our bioproducts and bio-attributed products production capacity to 1 million tons including the use of renewable feedstock and (iii) to expand the commercialization of resins and chemicals products with recycled content to reach 1 million tons by 2030, including the objective of recovering plastic waste and the commercialization of products with recycled content, as these are directly related. Execution and achievement of these objectives within the projected costs and expected timeframes are also subject to risks and uncertainties which include, but are not limited to: capital, advancement, availability, development and affordability of technology necessary to achieve these commitments; unforeseen design, operational and technological difficulties; availability of necessary materials and components; adapting products to customer preferences and customer acceptance of sustainable supply chain solutions; changes in public sentiment and political leadership; our ability to comply with changing regulations, taxes, mandates or requirements related to greenhouse gas emissions or other climate-related matters. The transition to technologies that reduce greenhouse gas emissions, along with the impact of carbon pricing, evolving public opinion, new regulations, taxes, public mandates, and the rise in climate-related lawsuits and insurance premiums, as well as the implementation of disaster recovery and business continuity plans, could lead to higher costs. These increased costs might make it harder for us to maintain or resume our operations or meet our sustainability objectives within the expected timeframes, which could negatively impact our business, financial health, operational results, and cash flow. Risks Relating To Our Shareholders Some of our shareholders may have the ability to determine the outcome of corporate actions or decisions, which could affect the holders of our class A preferred shares and the ADSs. Novonor S.A. – Em Recuperação Judicial (“Novonor”), directly or through its wholly-owned subsidiary NSP Investimentos S.A., or NSP Inv., owns 38.3% of our total share capital, including 50.1% of our voting share capital, and Petrobras holds 36.1% of our total share capital, including 47.0% of our voting share capital. Nominees of Novonor constitute a majority of the members of our board of directors. Under a shareholders’ agreement to which Novonor and Petrobras are parties, which we refer to as the Braskem S.A. Shareholders’ Agreement, all matters that may be resolved at a shareholder’s meeting or by our board of directors shall be decided by consensus among Novonor and Petrobras (except for our business plan, which is approved separately by the directors appointed by Novonor, as described under “Item 7. Major Shareholders and Related Party Transactions—Major Shareholders—Shareholders’ Agreements”), taking into account our best interest. Furthermore, the shareholders’ agreement provides for the possibility (and not the obligation), if deemed necessary, to hold prior meetings, as a legitimate mechanism for alignment between Novonor and Petrobras, with a view to ensuring consistency and uniformity in their decisions, which could affect holders of class A Preferred Shares and American Depositary Shares, or ADSs. 27 Table of Contents Furthermore, on June 17, 2019, Novonor, together with certain of its controlling and controlled entities, filed a petition for judicial restructuring before the First Judicial Bankruptcy Court of the State of São Paulo, Brazil, seeking a judicial restructuring and emergency relief staying certain foreclosure actions by their secured creditors, or the Novonor Judicial Restructuring Proceedings. The Novonor Judicial Restructuring Proceedings does not include us. We are exposed to certain risks related to the Novonor Judicial Restructuring Proceedings, such as risks related to the change of our corporate control resulting from decisions taken and/or agreed in the context of such proceedings and the consequences derived thereto, including but not limited to significant changes in our management and our strategy that may be undertaken by any new controlling shareholders that may arise from the conclusion of these proceedings. We have no control over the Novonor Judicial Restructuring Proceedings, and no assurance can be given on the outcome of the Novonor Judicial Restructuring Proceedings or their effect on us. We may be subject to attempts to acquire our control, which may lead to significant changes in management, the strategies that we are currently pursuing, or in our current corporate governance practices. We may be subject to attempts to acquire our control. In the event there is a change in our corporate control, there might be significant changes in management, the strategies that we are currently pursuing, or in our current corporate governance practices. In addition, under shareholders’ agreements in certain joint ventures we are a party to, in the event there is a change in our corporate control, our partner could execute a call option right and buy our shares in such joint ventures. All common and preferred shares issued by us and held by NSP Inv. were pledged with fiduciary assignment (alienação fiduciária) as a collateral given under certain financing agreements entered into by Novonor and certain of its subsidiaries with specific non-bankruptcy creditors (credores extraconcursais). It is possible that, under certain circumstances, the pledge over such shares may be enforced, with the consequent sale of the shares, which could result in a change of Braskem’s control and other consequences arising therefrom. On August 7, 2020, we received a correspondence from our controlling shareholder, Novonor, informing that, in order to fulfill certain commitments assumed with bankruptcy and non-bankruptcy creditors (credores concursais e extraconcursais), it had taken preliminary measures to structure a process for the private sale of up to its total equity ownership in our company, which, if implemented, will result in the change of our corporate control, adopting the necessary measures to organize such process, with the support of legal and financial advisors. On December 15, 2025, we received a correspondence sent by Novonor S.A – Em Recuperação Judicial and Shine I Fundo de Investimento em Direitos Creditórios de Responsabilidade Limitada, represented by its manager Vórtx Capital Gestora De Recursos Ltda. (“FIDC”), advised by IG4 Sol. Ltda., informing about the execution of (i) a definitive binding agreement between the FIDC and the creditor banks of NSP Investimentos S.A. (“NSP Inv.”) and other entities of the group Novonor S.A. – Em Recuperação Judicial (“Grupo Novonor”) to acquire all the credits held by the aforementioned banks against Novonor guaranteed by, among others, fiduciary assignment constituted on the shares issued by the Company held by NSP Inv. (“Transaction”); and (ii) exclusivity agreement with an initial term of sixty (60) days between FIDC and Novonor regarding a potential transaction involving the shares issued by Braskem held by NSP Inv. On March 6, 2026, the Administrative Council for Economic Defense (CADE) General Superintendence (Superintendência Geral) issued a decision (despacho), through which it decided to approve, without restrictions, the Transaction. In addition, we are exposed to certain risks related to the Novonor Judicial Restructuring Proceedings, including risks related to the change of our corporate control resulting from decisions taken or agreed under such proceedings and the consequences derived therefrom. We have no control over the Novonor Judicial Restructuring Proceedings, and no assurance can be given on the outcome of the Novonor Judicial Restructuring Proceedings or their effect on us. 28 Table of Contents We may face conflicts of interest in transactions with related parties. We maintain trade accounts receivable and current and long-term payables with related parties, including Petrobras and its subsidiaries, which is our main Brazilian supplier of naphtha and other raw materials such as propylene, ethane, propane and refinery off gas just as logistics supplier, and Novonor and its subsidiaries. These trade accounts receivable and trade accounts payable balances result mainly from purchases and sales of goods, which are mainly made based on international price references. These and other transactions between us and our related parties can result in conflicting interests, which may adversely affect our results of operations and financial condition. Furthermore, the shareholders’ agreement provides for the possibility (and not the obligation), if deemed necessary, to hold prior meetings, as a legitimate mechanism for alignment between Novonor and Petrobras, with a view to ensuring consistency and uniformity in their decisions, which could affect holders of class A Preferred Shares and American Depositary Shares, or ADSs. If we are unable to comply with the restrictions, covenants or guarantees in the agreements governing our, or certain subsidiaries, indebtedness and liabilities, there could be a default under the terms of these agreements, which could result in an acceleration of payment of funds that we have borrowed or guaranteed and could affect our ability to make principal and interest payments on our debt and liabilities obligations. Any default under the agreements governing our, and certain of our subsidiaries’, indebtedness or liabilities that is not cured or waived by the required lenders or noteholders could result in the holders of any such indebtedness or liabilities accelerating the payment of amounts outstanding, which could potentially render us unable to pay principal and interest on those and other obligations. If we are unable to generate sufficient cash flow or otherwise fail to obtain the funds necessary to meet required payments of principal and interest on our indebtedness, or if we otherwise fail to comply with the various covenants in the agreements governing our indebtedness or liabilities, we could be in default under the terms of such agreements. In the event of such default: · the holders of such indebtedness could elect to declare all the funds borrowed thereunder to be due and payable, together with accrued and unpaid interest; · the lenders or noteholders under such agreements could elect to terminate their commitments thereunder and cease making further loans; · the acceleration under such indebtedness may trigger cross-acceleration provisions under other financing arrangements entered into by us; and · we could be forced into bankruptcy or liquidation. Certain of our contractual arrangements, including debt obligations, contain certain change of control provisions that provide our counterparties with a termination right or the ability to accelerate the maturity of our indebtedness in the event of a change of our control without their consent and/or a ratings decline, as applicable. Furthermore, in October 2023, with the support of its shareholders, Braskem Idesa and Advario, TQPM entered into a syndicated project finance loan agreement in the principal amount of R$1,975 million (US$408 million) with a 5 (five) year short-term loan deal with standard guarantees for transactions of this type. The project financing taken by TQPM for the construction of the ethane import terminal in Mexico is also guaranteed by an Equity Support Agreement provided by the Company that, as of the end of December 2025, covers 50% of the financing balance of TQPM, with the remaining 50% guaranteed by the other TQPM shareholder until the project perfection collateral date (which includes the authorization from the local energy regulator – CRE/CNE – to pledge certain assets of TQPM to the syndicated lenders). After reaching such milestone, the Company is committed to provide support covering 100% of the monthly payments for the offtake agreement entered by Braskem Idesa and TQPM up to the outstanding amount of TQPM financing. In addition, pursuant to the indentures governing our 4.500% Notes due 2028, 4.500% Notes due 2030, 8.500% Notes due 2031, 7.250% Senior Notes due 2033, 8.000% Senior Notes due 2034, 7.125% Notes due 2041, 5.875% Notes due 2050, Subordinated Resettable Fixed Rate Notes due 2081, 15th Debentures Issuance (used as a security for the issuance of a CRA – Agribusiness Receivables Certificates), 16th Debentures Issuance, 17th Debentures Issuance and 18th Debentures Issuance, a “change of control” with a “ratings decline” (as such terms may be defined in each agreement governing our indebtedness) would require a repurchase of, or an offer to repurchase, any such outstanding notes or debentures, plus accrued and unpaid interest, if any, to the repurchase date. 29 Table of Contents These provisions would be triggered, for example, in the event a third party acquires, directly or indirectly, more than 50% of our voting capital stock outstanding and if, because of such a “change of control” (as such term may be defined in each agreement governing our indebtedness) our ratings are downgraded under certain thresholds (a “ratings decline,” as such term may be defined in each agreement governing our indebtedness) within a certain period of time. In the case of our 4.500% Notes due 2028, 4.500% Notes due 2030, 7.125% Notes due 2041, 5.875% Notes due 2050 and Subordinated Resettable Fixed Rate Notes due 2081, a “ratings decline” would occur if, at any time within 90 days after the earlier of the date of public notice of a “change of control” and the date on which Braskem and/or any other “person” (as applicable, and as defined in each agreement governing our indebtedness) publicly declares its intention to effect a “change of control,”: (i) in the event the notes are assigned an investment grade rating by at least two rating agencies prior to such public notice or declaration, the rating assigned to the notes by at least two of the rating agencies is below an investment grade rating; or (ii) in the event the ratings assigned to the notes by at least two of the rating agencies prior to such public notice or declaration are below an investment grade rating, the rating assigned to the notes by at least two of the rating agencies is decreased by one or more categories (i.e., notches); provided that, in each case, any such “ratings decline” is expressly stated by the applicable rating agencies to have been the result of the “change of control.” In the case of our 8.500% Senior Notes due 2031, 8.000% Senior Notes due 2034 and 7.250% Senior Notes due 2033, a “ratings decline” would occur if, at any time within 90 days after the date of public notice of a “change of control,” (i) in the event the notes are assigned an investment grade rating by at least two rating agencies prior to such public notice, the rating assigned to the notes by any two or more of the rating agencies is below an investment grade rating; or (ii) in any other case, the rating assigned to the notes by at least two of the rating agencies is decreased by one or more categories (i.e., notches); provided that, in each case, any such “ratings decline” is expressly stated by the applicable rating agencies to have been the result of the “change of control.” As a result, if a third party acquires our control, whether as a result of the Novonor Judicial Restructuring Proceedings (or agreements entered into within the context of the Novonor Judicial Restructuring Proceedings) or otherwise, such acquisition may result in a ratings downgrade that constitutes a “ratings decline.” In such cases, if appropriate consents or waivers are not obtained, such creditors could accelerate the maturity of our indebtedness or as applicable, require a repurchase of, or an offer to repurchase, our outstanding notes or debentures. The termination of any of our contractual arrangements, the acceleration of the maturity of, or the requirement to repurchase or offer to repurchase any of our indebtedness may have a material adverse effect on our business, financial condition, results of operations and cash flows, and ultimately result in the cross-acceleration of all of our indebtedness. There can be no assurance that Novonor will remain our controlling shareholder. Novonor and Petrobras may enter into transactions or other arrangements that may result in us not having a controlling shareholder. If no single shareholder or group of shareholders holds more than 50% of our voting stock or exercise a controlling interest, there may be increased opportunity for alliances between shareholders and conflicts between them. Currently, Novonor, directly or through its wholly-owned subsidiary NSP Inv., owns 38.3% of our total share capital, including 50.1% of our voting share capital, and Petrobras holds 36.1% of our total share capital, including 47.0% of our voting share capital. Each of Novonor (our indirect controlling shareholder) and Petrobras are currently a party to a shareholders’ agreement governing the exercise of their voting rights, appointment of directors and officers and other matters related to our corporate governance and their interests in us. In the event there is a change in our corporate control, we may be subject to significant changes to our management, business plan and strategies, as well as to our current corporate governance practices, all of which may have a material adverse effect on our results of operations and financial condition. 30 Table of Contents On November 3, 2022, we received a correspondence from Novonor, informing that, due to the discussions and analysis currently underway relating to a possible transaction, it may be necessary for Braskem to interact with potential interested parties, for which Novonor asked for our support and for that of our officers. Novonor further informed that, at that moment, there was no exclusivity agreement with any interested party, no binding offer, and no definition or decision on the structure to be adopted or on any alternative related to the disposal process. In addition, as disclosed by us on December 16, 2021, we were notified by Novonor and Petrobras that each of their governance bodies approved, on December 15, 2021, the execution of a term sheet providing for Novonor’s and Petrobras’ mutual commitment to take necessary measures that could, if implemented, ultimately result in a change of control of our company (the “Notice”). If we migrate to the Novo Mercado in the future, all of our class A and class B preferred shares will be converted into common shares, resulting in Novonor no longer holding indirectly the majority of our voting stock. Even if Novonor and Petrobras enter into a new shareholders’ agreement, the potential material sale of our common shares held by either or both of them could leave Novonor and Petrobras with less than 50% plus one share of our voting stock. Irrespective of whether the transactions described in the Notice are implemented, Novonor or Petrobras may initiate discussions regarding other transactions that could ultimately have similar effects in the future. Should Novonor and Petrobras cease to hold more than 50% of our voting stock, there can be no assurance that the influence by such shareholders will be maintained, including, without limitation, in relation to corporate governance, business plan, strategical, and key management matters. If a control group emerges with decision-making power over us, we may experience sudden and unexpected changes to our corporate governance and strategic policies, including through the replacement of directors and key executive officers. The absence of a controlling shareholder or controlling group of shareholders may also affect our decision-making process, as the minimum quorum required by Brazilian law for certain decisions by shareholders may not be reached. In that case, we may be unable to pursue our business plan effectively to pursue our business plan and strategies effectively. Additionally, we may be more vulnerable to a hostile takeover. Additionally, all common and preferred shares issued by Braskem and held by NSP Inv. were pledged with fiduciary assignment (alienação fiduciária) as a collateral given under certain financing agreements entered into by Novonor and certain of its subsidiaries with specific non-bankruptcy creditors (credores extraconcursais). It is possible that, under certain circumstances, the pledge over such shares may be enforced, with the consequent sale of the shares, which could result in a change of Braskem’s control and other consequences arising therefrom. On December 15, 2025, we received a correspondence sent by Novonor S.A – Em Recuperação Judicial and Shine I Fundo de Investimento em Direitos Creditórios de Responsabilidade Limitada, represented by its manager Vórtx Capital Gestora De Recursos Ltda. (“FIDC”), advised by IG4 Sol. Ltda., informing about the execution of (i) a definitive binding agreement between the FIDC and the creditor banks of NSP Investimentos S.A. (“NSP Inv.”) and other entities of the group Novonor S.A. – Em Recuperação Judicial (“Grupo Novonor”) to acquire all the credits held by the aforementioned banks against Novonor guaranteed by, among others, fiduciary assignment constituted on the shares issued by the Company held by NSP Inv. (“Transaction”); and (ii) exclusivity agreement with an initial term of sixty (60) days between FIDC and Novonor regarding a potential transaction involving the shares issued by Braskem held by NSP Inv. On March 6, 2026, the Administrative Council for Economic Defense (CADE) General Superintendence (Superintendência Geral) issued a decision (despacho), through which it decided to approve, without restrictions, the Transaction. 31 Table of Contents Any unexpected change to our management team, business plan and strategies, any dispute between our shareholders, or any attempt to acquire our control may divert our management’s attention and also have an adverse effect on our business plan, strategies, financial condition and results of operations. We lost the right of preference set forth in the current shareholders’ agreement with respect to new business opportunities in the petrochemical sector, and as result, Petrobras, which is our largest supplier of raw materials in Brazil, will be able to invest in the petrochemical sector independently from us and without first giving us a preference to do so. Novonor and Petrobras are currently parties to a shareholders’ agreement that provides, among other matters, for the commitment between them to use their best efforts in the development of new business opportunities in the “petrochemical sector” (defined as business opportunities that involve: (i) the use of ethylene and propylene for the manufacture of PE, PP, PVC and cumene; (ii) petrochemical investments for the production of butadiene, paraxylene, PE, PP, PVC, cumene, PTA and PET, as well as the sale of these products; (iii) investments based on pyrolysis of hydrocarbons for the petrochemical industry; and (iv) other investments or products that Novonor and Petrobras may agree in good faith to include in the definition of the “petrochemical sector” relating to new production processes that may be developed in the future), with a right of preference given to us. Subject to some exceptions related to specific projects, if there is a direct or indirect business initiative, opportunity, undertaking, investment or participation that each of Novonor or Petrobras intends to pursue in the petrochemical sector (an “Opportunity”) that overlaps with certain objectives described in such shareholders’ agreement, the party that identified the Opportunity (the “Identifying Party”) shall grant Braskem a preference to explore the Opportunity. If we do not express an interest in exercising the right of preference over a given Opportunity, and the Identifying Party subsequently decides to pursue such Opportunity, the Identifying Party shall offer us the right to market the products related to the Opportunity under mutually satisfactory market conditions. On December 15, 2021, Novonor and Petrobras entered into an amendment to such shareholders’ agreement, generally providing that, if Braskem’s potential migration to the Novo Mercado listing segment of the B3 was not implemented, Braskem’s right of preference with regard to any future Opportunity would lapse by October 31, 2024. Because the migration of Braskem to the Novo Mercado listing segment of the B3 was not completed by October 31, 2024, Braskem lost its right of preference with regard to any future Opportunity. The loss of the right of preference with regard to an Opportunity may result in a decision by Petrobras, which is Braskem’s largest supplier of raw materials in Brazil, to invest in the petrochemical sector, which may affect the implementation of our strategic and growth plans and adversely affect our revenues and results of operations. Risks Relating To Legal And Regulatory Matters Adjustments in tariffs on imports that compete with our products could cause us to lower our prices. The Brazilian government has used import tariffs to implement economic policies. As a result, import tariffs imposed on petrochemical products have varied in the past and may vary in the future. Until November 2021, tariffs on imports of first-generation petrochemical products varied between 0% and 4%, and tariffs on polyethylene, polypropylene and PVC resins were 14.0%. In November 2021, the Brazilian government unilaterally reduced by 10% the import tariff rates of 87% of all its internationally commercialized goods. In May 2022, Brazil reduced, unilaterally, by an additional 10% tariffs on certain exports, which were expected to remain in force until December 2023 at the level of 11.2%. 32 Table of Contents In July 2022, Mercosur decided to reduce permanently the Common External Tariff (TEC) by 10%, which was applicable to all Mercosur members. Following these changes, tariffs on imports of first-generation petrochemical products from Mercosur members now vary between 0% and 3.6%, and tariffs on polyethylene, polypropylene and PVC resins are set at 12.6%. In August 2022, the Brazilian government also enacted Resolutions Nos. 369 and 381 of the Executive Management Committee of Chamber of Foreign Trade (“Gecex”) approving a reduction in the import tax, by inclusion in the List of Exceptions to the Mercosur Common External Tariff (“Letec”) for the following of our products: (i) ethylene and alpha-olefin copolymers with density lower than 0.94, from 11.2% to 3.3%; (ii) S-PVC resin obtained from suspension processes, from 11.2% to 4.4%; (iii) PP (propylene copolymer) resin, from 11.2% to 4.4%; and (iv) PP (propylene homopolymer), from 11.2% to 6.5%. This reduction was valid for one year, from August 5, 2022 until August 2023. We have historically prioritized supply to the Brazilian market, and currently there are no signs of shortages of the products we supply to the Brazilian market. On March, 21, 2023, the Executive Management Committee (“Gecex”) of the Foreign Trade Chamber (“Camex”) decided to remove certain products from Letec and adjust their import tax rates. The changes are as follows: the tax rate for ethylene and alpha-olefin copolymers (with a density of less than 0.94) increased from 3.3% to 11.2%; the tax rate for PVC-S resin (produced by a suspension process) increased from 4.4% to 11.2%; and the tax rate for PP "cup" resin (propylene copolymer) increased from 4.4% to 11.2%. The PP (propylene homopolymer) remained in Letec until July 31, 2023, after which its import duties were also raised to 11.2%. On November 10, 2023, the Gecex of Camex decided to reestablish import tariffs on 73 chemical products that were included in Resolution 353/2022 (the second unilateral reduction of 10% of the External Common Tariff (Tarifa Externa Comum) (“TEC”). The measure was taken aiming at reversing the negative impacts caused to the national industry, especially related to the surge in imports and the strong price variation that resulted from the 10% reduction in import tax that had been implemented. Therefore, as of November 28, 2023, the import tax applied to Braskem resins returned to the TEC level, being set at 12.6%. On September 18, 2024, the Executive Management Committee (Comitê-Executivo de Gestão) of Brazil’s Chamber of Foreign Trade (Câmara de Comércio Exterior, the “Camex”) approved an increase in the import tax from 12.6% to 20%, by adding the following products to the List of Temporary Tariff Increases due to Structural Trade Imbalances of Camex, which are marketed by us: (i) PE resins: certain types of other PE without fillers; certain other copolymers of ethylene and vinyl acetate; and certain copolymers of ethylene and alpha-olefins; (ii) polypropylene (“PP”) resins: certain types of PP; and certain copolymers of PP; and (iii) PVC resins: certain PVC products. This increase is effective for one year from the publication of the decision in the Brazilian Federal Official Gazette, valid from October 15, 2024, to October 14, 2025. On October 17, 2025, the 20% import tax maintenance was approved by Camex through October 16, 2026. Adjustments of tariffs could lead to increased competition from imports and cause us to lower our domestic prices and impact the demand for our products, which would likely result in lower net revenue and could negatively affect our overall financial performance. Additionally, the products we export to the United States and Europe are subject to tariffs in the amount of 6.5% in each jurisdiction, subject to certain preferences. These tariffs generally balance the level of competition of our products produced locally and any future adjustments to these tariff structures could negatively impact our sales in these jurisdictions. Future trade agreements entered into by Brazil, the Mercosur, the United States or the European Union could also lead to increased competition from imports and lower domestic prices. Changes in U.S. and global trade policies and other factors beyond our control may adversely impact our business, financial condition and results of operations. The international environment in which we operate is affected from inter-country trade agreements and tariffs. As a result of recent changes to United States administrative policy, there are, and there may be additional changes to existing trade agreements, greater restrictions on free trade and significant increases in tariffs on goods imported into the United States. Future actions of the United States administration and that of foreign governments, including China, with respect to tariffs or international trade agreements and policies remains currently unclear. 33 Table of Contents The escalation of a trade war, tariffs, retaliatory tariffs or other trade restrictions on products and materials including those exported by us to China or raw materials imported by us from China, or other countries, may significantly hinder our ability to provide our products to customers in China or other affected locations. Such developments may result in a decrease in demand for our products as well as delays in payments from our customers. Furthermore, other governmental action related to tariffs or international trade agreements, changes in U.S. social, political, regulatory and economic conditions, or in laws and policies governing foreign trade, manufacturing, development and investment in the territories and countries where our customers are located, could lead to a rebalancing of global export flows and an increase in global competition, which in turn could adversely affect our business, financial condition, results of operations and cash flows. New Tariffs Imposed or Threatened by the United States Could Result in Increased Costs The new United States administration has imposed or threatened to impose tariffs ranging from 10 to 25% on a variety of countries, including China, Mexico, Canada, and the European Union, and products, including steel, aluminum, copper, automobiles, and lumber and is likely to continue to do so in the future. In addition, the United States has threated the imposition of reciprocal tariffs on those countries who impose unequal tariffs or taxes on United States exports. While to date the only United States tariff increases in effect are the additional 20% tariffs on United States imports from China, the 25% tariff on United States imports of steel and aluminum, and the 25% tariff on United States imports from Canada and Mexico (excluding imports from Canada and Mexico that qualify for exemptions under the United States-Mexico-Canada Agreement (the “USMCA”), there is no guarantee that other threatened tariff increases will not become effective in the future. Given the current uncertainty around the threat of tariff increases, it is not possible to estimate the potential effect or to determine the level of materiality to the Company. Such tariff increases, if adopted and applicable to United States imports by the Company or its suppliers, could result in increased costs, including potential costs related to shifting more production to the United States or other countries, which might be material to the Company. The retaliatory tariffs adopted by third countries could also have similar effects on products of the Company being exported into those countries. Failure to comply with export control or economic sanctions laws and regulations could have a material adverse impact on our results of operations, financial condition and reputation. We operate on a global basis and face risks related to compliance with export control and economic sanctions laws and regulations, including those administered by the United Nations, the European Union and the United States, including the U.S. Treasury Department’s Office of Foreign Assets Control. Economic sanctions programs restrict our dealings with certain sanctioned countries, territories, individuals and entities. Economic sanctions are complex, frequently changing, and often increase in number, and may impose incremental prohibitions, fines, restrictions on dealings with additional countries, territories, individuals or entities or compliance obligations on our dealings in certain countries and territories. We have conducted, and may in the future seek to conduct, business in certain countries that are subject to sanctions under the laws of the United States, the European Union, or other countries. Although we have pursued these transactions, and intend to pursue any future transactions, in full compliance with applicable laws and regulations, we may not be successful in ensuring compliance with limitations or restrictions on business with companies in any such countries. Additionally, Russia’s annexation of Crimea, recognition of two separatist republics in the Donetsk and Luhansk regions of Ukraine, and the military interventions in Ukraine have led to sanctions and other penalties being imposed by the United States, the European Union and other countries on Russia, Belarus, the Crimea Region of Ukraine, the so-called Donetsk People’s Republic, and the so-called Luhansk People’s Republic, including the agreement to remove certain Russian financial institutions from the Society for Worldwide Interbank Financial Telecommunication (“SWIFT”) payment system. 34 Table of Contents Additional potential sanctions and penalties have also been proposed and/or threatened and the United States and other countries could impose wider sanctions and take other actions should the conflict further escalate. If we are found to be in violation of applicable sanctions laws or regulations, we may face criminal or civil fines or other penalties, we may suffer reputational harm and our results of operations and financial condition may be adversely affected. Additionally, even though we have adopted a global trade control directive and provide regular training to our employees, there can be no assurance that our employees, directors, officers, partners or any third parties that we do business with, including, among others, any distributors, or suppliers, will not violate sanctions laws and regulations. We may ultimately be held responsible for any such violation of sanctions laws and regulations by these persons, which could result in criminal or civil fines or other penalties, have a material adverse impact on our results of operations and financial condition and damage our reputation. We may not be able to specify in details technical specifications required by our customers’ or updated mechanisms to promptly attend regulatory requirements, and we could be subject to damages based on claims brought against us or our customers as a result of the failure of our products specification. Our products specifications may not meet certain technical or regulatory requirements, specifications or standards. In addition, our customers may impose stricter requirements on our products or governments may enact stricter regulations for the distribution, sale or use of our products. Failure to meet such standards could materially adversely affect our business, financial condition and results of operations if we are unable to sell our products in one or more markets or to important customers in such markets. As with all quality control systems, any failure or deterioration of our quality control systems could result in defects in our products, which in turn may subject us to contractual, regulatory, product liability and other claims, which could have a material adverse effect on our reputation, business, financial condition and results of operations. We may not be able to obtain or renew all licenses, permits and authorizations necessary for conducting our business. We are subject to a wide variety of federal, state and municipal laws, regulations and licensing requirements, and depend on obtaining licenses, permits and authorizations to carry out our activities. We cannot guarantee that we will be able to maintain, renew or obtain any new authorization, license, grant, or permit, in a timely manner, or that any additional requirements will not be imposed in connection with such renewal order. Failure to obtain or maintain the permits, authorizations and licenses necessary for our operations, or failure to obtain or timely maintain them, may result in fines, loss or early termination of permits, authorizations and/or licenses, as well as closing of plants, or breach of financing and commercial contracts, which could have a material adverse effect on our results of operations and financial condition. We could be materially adversely affected by the impacts of the Global Settlement. On December 14, 2016, we entered into a leniency agreement with the MPF (the “Leniency Agreement”), which was ratified by the competent Brazilian court on June 6, 2017. On December 21, 2016, we (i) filed a plea agreement in the United States District Court for the Eastern District of New York under which we agreed to plead guilty to a one-count criminal information charging us with conspiracy to violate the anti-bribery provisions of the U.S. Foreign Corrupt Practices Act (the “FCPA”) and (ii) consented to the entry of a final judgment in a civil action brought by the SEC based on civil violations of the anti-bribery, books and records and internal accounting controls provisions of the FCPA. The competent federal courts in the United States approved the U.S. Department of Justice (the “DoJ”) and SEC resolutions on January 26, 2017 and February 28, 2017, respectively. In addition, on December 21, 2016, the Swiss Attorney General’s Office (“OAG”) closed its investigation of these matters. We refer to these actions as the “Global Settlement.” Under the Global Settlement, we agreed to pay to the governmental authorities in these jurisdictions an aggregate amount of US$957 million (equivalent to R$3.1 billion), based on the exchange rate of R$3.27 per U.S. Dollar, applicable at the time of the negotiation. 35 Table of Contents Pursuant to the Global Settlement, the MPF agreed to communicate with other public authorities or entities, as well as stated-owned companies and mixed-capital companies with which Braskem enters into discussions to address the facts under the Global Settlement and avoid making duplicate restitution payments. In this context, pursuant to the notice to the market disclosed on Form 6-K on July 11, 2018, and the material fact disclosed on Form 6-K on May 27, 2019, we have cooperated and engaged in negotiations with the Ministry of Transparency and Controllership (CGU) and the Office of the Attorney General (AGU) in Brazil, and our Board of Directors approved the signing of a leniency agreement with the CGU and the AGU (the “CGU/AGU Agreement”). The CGU/AGU Agreement, in the amount of R$2.9 billion, to be adjusted by the SELIC rate, addresses the same facts that are the object of the Global Settlement executed in December 2016 with the Brazilian Federal Prosecution Office (MPF), the DoJ, the SEC and the Swiss Office of the Attorney General. Of this amount, R$3.1 billion will be offset by the amount that Company already had undertaken to pay under the scope of the Global Settlement, resulting in an additional disbursement of R$410 million. As of December 31, 2025, we had paid R$3.4 billion since 2016, as follows: · R$1,213 million to the AGU, CGU and MPF; · R$297 million to the DoJ; · R$407 million to the OAG; · R$1,282 million to the MPF; and · R$206 million to the SEC In August 2023, the Company was notified by CGU about the end of the monitoring period of the Company’s integrity program and also presented the closing of the monitorship. In February 2024, a decision was rendered by the Brazilian Supreme Court, within the scope of the Action against the Violation of a Constitutional Fundamental Right (“ADPF”) No. 1051, determining the renegotiation of leniency agreements. On December 19, 2024, the Company entered into an Amendment to the Leniency Agreement to adjust the payment schedule and other obligations and conditions, as outlined below: (i) 2025: installment of R$35 million; (ii) 2026: installment of R$35 million; (iii) 2027: installment of R$55 million; and (iv) 2028, 2029 and 2030: installments of R$158 million each. The CGU/AGU Amendment will be submitted for approval by the Federal Supreme Court (STF), in the ADPF records. As a result, from the renegotiation the Company has written off an amount of R$112 million from the provision. The amount payable under the Leniency Agreement, as of December 31, 2025, was R$673 million, of which R$90 million is classified as current liabilities and R$583 million is classified as non-current liabilities. 36 Table of Contents By reason of the Global Agreement, we will continue to cooperate with these relevant governmental authorities and improve our governance and anti-corruption compliance practices. Over the three years between 2017 and 2020, we were subject to independent monitoring as a result of the Agreements (the “CGU/AGU Agreement” and, together with the Global Agreement, the “Agreements”). Such monitors were responsible for verifying compliance with the Global Agreement, as well as the effectiveness of our internal controls, policies and procedures to reduce the risk of non-compliance with anti-corruption laws. We are in compliance with all of our obligations under the Agreements and continue to cooperate with government authorities. The Global Settlement does not prevent us from being held liable to any legitimate third party, which may seek indemnification for damages for the facts subject to the agreements, including other authorities with jurisdiction over us may seek to impose monetary sanctions or fines on, or to initiate investigative proceedings against us, which could adversely affect our results of operations and financial condition. We cannot guarantee that the total amount agreed will be sufficient to repair any harm fully. Unfavorable outcomes in pending or future litigation may reduce our liquidity and negatively affect our financial performance and financial condition. We are, and in the future may be, involved in numerous tax, civil, environmental and labor disputes, among others, involving monetary claims and guarantees including equity in our subsidiaries. If unfavorable decisions are rendered in one or more of these lawsuits, we could be required to provide guarantees or pay substantial amounts. For certain of these lawsuits, we have not established any provision on our statement of consolidated financial position or have established provisions only for a portion of the amounts in controversy, based on our judgments as to the risk of loss for these lawsuits. In the context of the geological events occurred in Maceió, we entered into agreements for the termination of three public-interest civil actions (ACP Labor, ACP Socio-environmental and ACP of Residents). The terms of the settlements were as follows: · ACP Labor settlement: in February 2020 we committed to investing R$40 million to fund a Business Recovery and Promotion of Educational Activities Program for residents and workers in the districts of Mutange, Bom Parto, Pinheiro and Bebedouro in Maceió, in the state of Alagoas. This agreement has been fulfilled in its entirety. · ACP of Residents settlement: through an Instrument of Agreement to Support the Relocation of People in Risk Areas, which was ratified by the court in January 2020 and updated in December 2020, we committed to supporting the relocation and compensating residents, merchants, business owners and property owners located in the risk areas defined in the Civil Defense Map subject to relocation, by offering proposals for financial compensation and entering into individual agreements ratified in court (as of December 31, 2021, the risk area encompasses approximately 15,000 properties); and · ACP Socio-environmental settlement: in December 2020, we committed to (i) adopting the necessary measures to stabilize the cavities and monitor the soil, implementing the measures of the mine closure planning presented to ANM and subject to its approval; (ii) repairing, mitigating or compensating potential environmental impacts and damages resulting from the mining activities (salt extraction) in the city of Maceió, to be defined by an Environmental Diagnosis developed by an expert and independent company approved by the Prosecutor’s Office; and (iii) allocating R$1.58 billion to implement measures in the vacated area, actions related to urban mobility and to compensate potential socio-urbanistic impacts and damages. The provisions of the Company are based on current estimates and assumptions and may be updated in the future due to new facts and circumstances, including, but not limited to: changes in the execution time, scope and method and the success of action plans; new repercussions or developments arising from the geological event, including possible revision of the Civil Defense Map; and possible studies that indicate recommendations from specialists, including the Technical Monitoring Committee, according to Agreement for Compensation of Residents and other new developments in the matter. The Company has been making progress in negotiations with private entities and government authorities about other indemnification claims, deepening its understanding, which may lead to future agreements. Although future disbursements may occur as a result of said negotiations, as of the reporting date, the Company is unable to predict the results and timeframe for concluding these negotiations or their scope and the total associated costs in addition to those already provisioned for. 37 Table of Contents Furthermore, the contingent liabilities whose loss is assessed as possible by the Company’s Management, based on its evaluation and that of its external legal advisors, related to the geological event in Alagoas in December 31, 2025 was R$8,132 million. On May 21, 2024, the final report of the Parliamentary Investigative Committee (“CPI”), set up by the Brazilian Senate on December 13, 2023, was approved, with the purpose of investigating the effects of the Company’s socio-environmental legal liability related to the geological event in Alagoas. On this date, the aforementioned CPI was declared closed, with the subsequent submission of the final report to the appropriate institutions. There are also administrative proceedings related to the geological event in Alagoas currently in progress before the Federal Accounting Court (“TCU”) and the Securities and Exchange Commission of Brazil (“CVM”). In October 2024, the Company was informed of the conclusion of the Federal Police investigation in Alagoas, which had been ongoing since 2019. The inquiry records were sent to the Prosecution Office for evaluation, which requested additional investigations. The Company has always made itself available to the competent authorities and has been providing all information related to salt mining over the course of the investigation. In October 2025, the MPF filed charges based on the final report of the Federal Police from October 2024. We have been making progress with local authorities about other indemnification requests to understand them better. Although future disbursements may occur because of progress in negotiations, as of the reporting date, we are unable to predict the results and timeframe for concluding these negotiations or its possible scope and the total associated costs in addition to those already provisioned for. It is not possible to anticipate all of the new claims related to damage or other nature that may be brought by individuals or groups, including public or private entities, that understand they suffered impacts or damages related to the geological event and the relocation of people from risk areas, as well as new notices of infraction or administrative penalties of diverse nature. Braskem continues to face and could still face administrative procedures and various lawsuits filed by individuals or legal entities not included in the PCF or that disagree with the financial compensation offer for individual settlement, as well as new collective actions and new lawsuits filed by public utilities, entities of the direct or indirect administration of the State of Alagoas, the Municipality of Maceió or the Brazilian federal government. Therefore, the number of such actions or lawsuits, their nature or the amounts involved cannot be accurately estimated at this time. Consequently, we cannot eliminate the possibility of future developments related to all aspects of the geological event in Alagoas, the relocation process and actions in vacated and adjacent areas, so the expenses to be incurred may differ significantly from our estimates and provisions. We could be materially affected by violations of the FCPA, the Brazilian Anti-Corruption Law and similar anti-corruption laws. We, our subsidiaries and our joint venture partners are subject to a number of anti-corruption laws, including Law No. 12,846/2013, or the Brazilian Anti-Corruption Law, which entered into effect on January 28, 2014, the FCPA and various other anti-corruption and anti-bribery laws of other jurisdictions. 38 Table of Contents The FCPA, the Brazilian Anti-Corruption Law and similar anti-bribery laws in other jurisdictions generally prohibit companies and their intermediaries from making improper payments to government officials or other persons for the purpose of obtaining or retaining business. Violations of these laws may result in criminal or civil sanctions, inability to do business with existing or future business partners, injunctions against future conduct, profit disgorgements, disqualifications from directly or indirectly engaging in certain types of businesses, the loss of business permits or other restrictions which could have a material adverse effect on our business, financial condition, results of operations or liquidity. Any negative reflection on our image or our brand from any violation of these laws could have a negative impact on our results of operations, as well as our ability to achieve our growth strategy. Furthermore, the Brazilian Anti-Corruption Law provides for joint and several liabilities between companies of the same economic group. Given the size of our operations and the complexity of our production chain, there can be no assurance that our internal policies and procedures will be sufficient to prevent or detect all inappropriate or unlawful practices, including fraud or violations of law or violations of our internal policies and procedures by our employees, directors, officers, partners or any third-party agents or service providers. Furthermore, there can be no assurance that such persons will not take actions in violation of our policies and procedures (or otherwise in violation of applicable laws and regulations) for which we or they may ultimately be held responsible. Violations of anti-fraud, anti-corruption, anti-money laundering or other international laws and regulations could have a material adverse effect on our business, reputation, brand, selling prices, results of operations and financial condition, including as a result of the closure of international markets. We may be subject to one or more enforcement actions, investigations or proceedings by authorities for alleged infringement of these laws. These proceedings may result in penalties, fines, sanctions or other forms of liability. We are exposed to behaviors of our employees, non-employees and third parties that may be incompatible with our ethics and compliance standards, and failure to timely prevent, detect or remedy any such behavior and/or process vulnerabilities may have a material adverse effect on our results of operations and financial condition. We are subject to the risk that our employees, partners, counterparties, or any person doing business with us may engage in fraudulent activity, corruption, or bribery, or circumvent, or override our internal controls and procedures or misappropriate or manipulate our assets for their personal or business advantage. Investigations conducted by us internally or through outside counsel on potential violations of any applicable anti-corruption laws, including the FCPA by our employees or agents can be expensive and require significant time and attention from senior management. Our Anti-Corruption Program may not be completely effective for identifying, monitoring, and mitigating these risks. In addition, we cannot guarantee the existence of a socially responsible value chain that offers decent working conditions. Any breach of work-related regulations could result in human rights violations, impacts on people’s quality of life, and poor work conditions, which in turn could have an impact on our results of operations due to potential financial implications and lawsuits brought by individuals, public authorities, or other agents, which could impact our reputation and image. In the future, we may be required to conduct additional procedures and analyses with respect to our internal processes and controls that may lead to a delay in the conclusion of our audited financial statements and, as a result, prevent us from filing future annual reports in a timely manner. Any failure to timely file our annual reports in the future may have an adverse effect on our business. Unauthorized disclosure or loss of intellectual property, sensitive confidential or personal information, or disruption to information technology systems by cyberattacks or other security breaches, as well as our failure to comply with data protection laws and information security requirements may subject us to significant penalties or liability and may adversely impact our operations, reputation, and financial results. We collect, store, process, and use certain sensitive confidential information and other personal data in connection with our business operations. We must ensure that any personal data activity such as processing, collection, use, storage, dissemination, transfer, and disposal of data for which we are responsible complies with relevant data protection and privacy laws. The protection of information relating to our business partners (customers and suppliers), employees and confidential information related to our business is critical to us. We rely on commercially available systems, software, and monitoring tools to provide secure processing, transmission, and storage of relevant information, such as business confidential information and personal data including sensitive information. 39 Table of Contents The Brazilian Constitution, Law No. 10,406/2002 (Civil Code), Law No. 8.078/1990 (Consumer Protection and Defense Code), Law No. 12.965/2014 (Brazilian Civil Rights Framework for the Internet), Decree No. 8771/2016 and the recent Law No. 13.709/2018 (Brazilian General Data Protection Law, or “LGPD”), which entered into force on September 18, 2020, are the main laws governing the practice of processing personal data in Brazil. The LGPD established a new legal framework for personal data processing transactions in Brazil. The LGPD also provided for administrative sanctions that can be applied in case of non-compliance with its provisions by the National Data Protection Authority (“ANPD”), which is responsible for preparing guidelines and supervising compliance with the law. Non-compliance with any provisions provided for in the LGPD may result in judicial or administrative proceedings enforcement by consumer protection agencies of penalties provided for in the sparse data protection regulation, such as those set forth in the Consumer Protection and Defense Code and the Brazilian Civil Rights Framework for the Internet. Since August 1, 2021, with the entry into force of the LGPD’s administrative sanctions, if the ANPD understands that we are not in compliance with the LGPD, we may be subject to individual or cumulative sanctions, warning, requirement to disclose the incident, temporary blocking and/or exclusion of personal data to which the violation refers, daily fine, simple fine of up to 2% of the company, group or conglomerate’s revenue in Brazil in its last fiscal year, excluding taxes, and up to the aggregate amount of R$50.0 million per infringement. In case of recurrence, more severe administrative penalties provided for in the LGPD may be applied. In addition, we may be held liable for material, moral, individual or collective damages caused to the holders of personal data, including when caused by our subsidiaries or by third parties that process personal data on our behalf or as controllers together with us due to non-compliance with the obligations provided by the LGPD. In this sense, we cannot guarantee that we will be successful in adapting our activities, procedures, documentation and the relationship with third parties hired by us to meet the high standards provided by the LGPD. Administrative sanctions or legal convictions may cause material financial impacts, in addition to adversely affecting our reputation in the market. Even if we adopt practices in line with the provisions and obligations set forth in the LGPD, it cannot be guaranteed that the measures adopted to adapt our personal data processing activities will be considered adequate or sufficient by ANPD, by other public authorities, such as the Public Ministry and consumer protection bodies, or by the court. Our failure to comply with any additional privacy laws or regulations enacted or approved in Brazil or in other jurisdictions in which we operate could seriously harm our business, financial condition or results of operations. For example, on May 25, 2018, Regulation No. 2016/279 of the European Parliament and of the Council of April 27, 2016 on the protection of personal data (the General Data Protection Regulation), or the GDPR, became directly applicable in all member states of the European Union. The GDPR has introduced new obligations relating to data privacy, control and retention, including, among others: (i) accountability and transparency requirements; (ii) enhanced data consent requirements; (iii) obligations to consider data privacy as any new products or services are developed and limit the amount of information collected, processed, stored and its accessibility; (iv) constraints on using data to profile data subjects; (v) providing data subjects with personal data in a useable format upon request and erasing personal data in certain circumstances; and (vi) reporting breaches without undue delay. As we seek to expand our business and operations, we expect to be increasingly subject to laws and regulations relating to personal data activity such as collection, use, retention, security, and transfer of our employee and customer data. These may change over time and may vary by jurisdiction, and it is possible they will be interpreted and applied in ways that will materially and adversely affect our business. Any failure—real or perceived—by Braskem to comply with any applicable privacy or data protection-related laws and regulations could cause our customers to reduce their use of our products and services. 40 Table of Contents Compliance with data protection laws requires us to expend resources to revise our procedures and policies. There are no guarantees that we have sufficient resources to comply with new regulations or to comply with this changing regulatory environment successfully. Further, there is a risk of improper implementation and sanctions or reputational damage for noncompliance, both of which could have a material adverse effect on our operations, financial condition, and prospects. Despite the information security measures that we have in place, our facilities and systems—and those of our third-party service providers—may be vulnerable to security breaches, cyberattacks (including ransomware and phishing), computer viruses, misplaced or lost data, programming or human errors, or other similar events. There has been an increasing number of cyberattacks globally. Any security breach or perceived threat resulting in the loss or other unauthorized disclosure of confidential information could damage our reputation, expose us to litigation risk and liability, subject us to negative publicity, disrupt our operations and harm our business. Cyberattacks or security breaches could compromise critical information and cause a disruption in our operations, which are heavily dependent on information technology and telecommunication systems and services. Information assets, including intellectual property, trade secrets, personal data and other business-sensitive critical information are an attractive asset to cyber criminals, cyberterrorism or other external agents. A significant cyberattack, a human error, including from our employees and partners, or obsolescence of technology could result in the loss of critical business information and/or negatively impact our operations, which could have a negative impact on our financial results. Our own security measures cannot be guaranteed and are susceptible to new cyberattacks. On October 4, 2020, we detected a cyberattack on our information technology environment and several improvements in people, processes and technologies have been and are being applied in the Company’s environment, significantly increasing the maturity of information security at Braskem. We believe that all these actions ensured that no new incidents happened to date. We are subject to audit by the tax authorities in the jurisdictions in which we operate, which may adversely affect our operating results and financial condition. We operate in and sell our products into several countries, including Brazil, Argentina, Colombia, Chile, the United States, Germany, the Netherlands, Mexico and Singapore, each with its own tax legislation and specific audit procedures. The tax legislation in each country are frequently ambiguous and subject to interpretation, which may lead to divergent views between the tax authorities in each country and us and/or our advisors. We operate in and sell our products into several countries, including Brazil, Argentina, Colombia, Chile, the United States, Germany, the Netherlands, Mexico and Singapore, each with its own tax legislation and specific audit procedures. The tax legislation in each country is frequently ambiguous and subject to interpretation, which may lead to divergent views between the tax authorities in each country and us and/or our advisors. Changes in tax laws may result in increases in certain direct and indirect taxes, which could reduce our gross margin and negatively affect our overall financial performance. We operate in several countries, including Brazil, Argentina, Colombia, Chile, the United States, Germany, Netherlands, Mexico and Singapore. Besides, we sell our products to several other countries through different commercial approaches. 41 Table of Contents Each of these countries has its own tax legislation, and these tax laws undergo frequent changes according to specific government purposes in each country. An example is the Brazilian government, which implements, from time to time, changes to tax regimes that may increase our and our customers’ tax burdens. These changes include modifications in the rate of assessments and, on occasion, enactment of temporary taxes. In addition, our tax treatment may be affected by tax policy initiatives and reforms related to the Organization for Economic Cooperation and Development (“OECD”), the work of the OECD/G20 inclusive framework on Pillar One and Pillar Two of the base erosion and profit shifting (“BEPS”) project and other initiatives. Pillar Two establishes a global minimum tax of 15% for each jurisdiction in which a multinational group operates. The Company is subject to the Pillar Two rules in Germany, Brazil, and the Netherlands. We cannot predict the changes to Brazilian tax law or in any other jurisdiction in which we operate that may be proposed and enacted in the future. However, future changes in these tax laws may result in increases in our overall tax burden, which could reduce our gross margin and negatively affect our overall financial performance. Risks Relating To Brazil Brazilian political, economic and business conditions, and the Brazilian government’s economic and other policies, may negatively affect demand for our products as well as our net revenue and overall financial performance. The Brazilian economy has been characterized by frequent and occasionally extensive intervention by the Brazilian government and unstable economic cycles. The Brazilian government has often changed monetary, taxation, credit, tariff and other policies to influence the course of Brazil’s economy. The Brazilian government’s actions to control inflation and implement other policies have at times involved wage and price controls, blocking access to bank accounts, imposing capital controls and limiting imports into Brazil. Our results of operations and financial condition may be adversely affected by factors such as: · expansion or contraction of the Brazilian economy, as measured by rates of growth in GDP; · fluctuations in exchange rates; · exchange control policies; · interest rates; · inflation; · tax policies and tax reforms; · liquidity of domestic capital and lending markets; and · other political, diplomatic, social, economic and business developments in or affecting Brazil. Brazilian markets have experienced heightened volatility due to the uncertainties derived from the corruption investigations by the Federal Prosecutor’s Office under Operations Car Wash, Zelotes, Greenfield, Efficiency and other investigations, and their impact on the Brazilian economy and political environment. Certain current and former members of the Brazilian government and of the legislative branch, as well as former senior officers of the state-owned oil company and our shareholder Petrobras have been prosecuted for political corruption. These government officials and former senior officers allegedly accepted bribes by means of kickbacks on contracts granted by Petrobras to several infrastructure, oil and gas and construction companies, including Novonor, our controlling shareholder. We cannot currently predict how the Operation Car Wash investigation, related investigations and any future decisions and actions by authorities or developments in relation to our shareholders, may impact us. The profits of these kickbacks allegedly financed the political campaigns of political parties of federal, state and city governments that were unaccounted for or not publicly disclosed, as well as served to personally enrich the recipients of the bribery scheme. 42 Table of Contents The potential outcome of these investigations is uncertain, but they have adversely affected and may continue to adversely affect the Brazilian markets and trading prices of securities issued by Brazilian issuers. The outcome of potential inquiries involving former president Jair Messias Bolsonaro and any new inquiries involving current president Luiz Inácio Lula da Silva, are uncertain, but they have had a negative impact on the general perception of the Brazilian economy and the securities of Brazilian companies and affected and may continue to adversely affect our business, our financial condition and results of operations. Additionally, uncertainties regarding a new government’s implementation of changes to monetary, tax, labor, and pension fund policies, as well as relevant legislation, may contribute to economic instability. These uncertainties and the measures adopted by a new administration could materially adversely affect our operations and increase the market volatility of Brazilian securities issued abroad. Changes in industrial policy and related actions undertaken by the Brazilian government and local state governments in Brazil may negatively affect demand for our products as well as our net revenue and overall financial performance. We currently benefit from certain industrial policies and related actions undertaken by the Brazilian government and local state governments in Brazil intended to strengthen the domestic economy and certain local industries. Some of these policies and actions have recently included reductions in payroll taxes for plastic manufacturers, a program to improve the competitiveness of Brazilian producers in the export markets by refunding, in part or in full, the federal taxes levied on their export sale, intervention of the federal government to reduce incentives to imports at local ports, increases in import duties on certain products, including polyethylene, and the reduction in the rates of the Social Integration Program (Programa de Integração Social, or PIS), a federal value-added tax, and Contribution for Social Security Financing (Contribuição para Financiamento da Seguridade Social, or COFINS), taxes on feedstock purchases by first- and second-generation petrochemical producers, reduction of the tax burden and tax incentives in certain regions to foster local industries. In December 2025, Law No. 15,294/25 was published, establishing the Special Sustainability Program for the Chemical Industry (Programa Especial de Sustentabilidade da Indústria Química, or “PRESIQ”), encompassing an incentive regime to stimulate the Brazilian chemical industry, effective from January 1, 2027 to December 31, 2031, in the industrial modality, related to the acquisition of certain chemical products, and the investment modality, related to the expansion or modernization of installed capacity. In March, 2026, Supplementary Law No. 228 was published in the Official Gazette of the Federative Republic of Brazil, providing for the increase, from 0.73% to 5.8%, of the benefit of the Special Regime for the Chemical Industry ("REIQ"), which corresponds to PIS/COFINS credits, based on feedstock of the chemical and petrochemical industries, subject to offsetting with federal taxes, the benefit will have a budget limit of R$2 billion for the sector and will be effective from March to December 31, 2026. We cannot predict or control which policies will be renewed or discontinued and whether future changes to Brazilian industrial policy will be proposed and enacted in the future. If industrial policies that benefit us expire, or policies detrimental to us are implemented, our business, results of operations and financial condition may be adversely affected. Fluctuations in the real/U.S. dollar exchange rate could increase inflation in Brazil, raise the cost of servicing our foreign currency-denominated debt and negatively affect our overall financial performance. The exchange rate between the real and the U.S. dollar and the relative rates of depreciation and appreciation of the real have affected our results of operations and may continue to do so. The Brazilian real has been devalued on several occasions. Throughout the last several decades, the Brazilian government has implemented various economic plans and various exchange rate policies, including sudden devaluations, periodic mini-devaluations (during which the frequency of adjustments has ranged from daily to monthly), exchange controls, dual exchange rate markets and a floating exchange rate system. From time to time, there have been significant fluctuations in the exchange rate between the Brazilian currency and the U.S. dollar and other currencies. The real depreciated by 4.0% during 2019, 28.9% during 2020, 7.4% during 2021, and appreciated by 6.5% during 2022, appreciated by 7.2% during 2023, depreciated by 27.9% in 2024, and appreciated by 11.1% in 2025. Depreciation of the real relative to the U.S. dollar also could result in inflationary pressures in Brazil by generally increasing the price of imported products and services. On the other hand, the appreciation of the real against the U.S. dollar may lead to a deterioration of the country’s current account and the balance of payments and may dampen export-driven growth. 43 Table of Contents We had total foreign currency-denominated debt obligations, all of which were denominated in U.S. dollars, in an aggregate amount of R$61,933 million (US$11,256 million) as of December 31, 2025, (including an aggregate amount of R$14,308 million (US$2,600 million) outstanding as of December 31, 2025, in connection with our secured debt related to our Mexico Complex), representing 93.7% of our consolidated indebtedness. As of December 31, 2025, we had R$6,368 million (US$1,157 million) in foreign currency-denominated cash and cash equivalents, including the aggregate amount of R$233 million (US$42 million) of Braskem Idesa’s cash and cash equivalents. A significant depreciation of the real in relation to the U.S. dollar or other currencies could increase our financial expenses as a result of foreign exchange losses that we must record and could reduce our ability to meet debt service requirements of our foreign currency-denominated obligations. To enable us to manage the effects of exchange rate fluctuations on our results, in 2013 we decided to designate part of our U.S. dollar-denominated liabilities as a hedge for our future exports. However, we cannot assure that the designation of part of our U.S. dollar-denominated liabilities as a hedge for our future exports will be enough to not affect our financial results. The hedge accounting program was prospectively discontinued as of December 2025. For additional information, see "ITEM 5. Operating and Financial Review and Prospects — Principal Factors Affecting Our Results of Operations — Effects of Fluctuations in Exchange Rates between the Real and the U.S. Dollar". The prices of naphtha, our most important raw material, and of some of our other raw materials, are denominated in or linked to the U.S. dollar. For the year ended December 31, 2025, naphtha accounted, directly and indirectly, for 30.2% of our consolidated cost of products sold. When the real depreciates against the U.S. dollar, the cost in reais of our U.S. dollar-denominated and U.S. dollar-linked raw materials increases, and our operating income in reais may decrease to the extent that we are unable to pass on these cost increases to our customers. The Brazilian government’s actions to combat inflation may contribute significantly to economic uncertainty in Brazil and reduce demand for our products. Historically, Brazil has experienced high rates of inflation. Inflation, as well as government efforts to combat inflation, had significant negative effects on the Brazilian economy, particularly prior to 1995. The inflation rate, as measured by the General Price Index—Internal Availability (Índice Geral de Preços—Disponibilidade Interna, or the “IGP-DI”), reached 2,708% in 1993. Although inflation rates have been substantially lower since 1995 than in previous years, inflationary pressures persist. Inflation rates, as measured by the IGP-DI, were negative 0.4% in 2017, positive 7.1% in 2018, 7.37% in 2019, 23.1% in 2020, 17.7% in 2021 and, 5.03% in 2022, negative 3.30% in 2023, positive 6.5% in 2024 and negative 1.2% in 2025. The Brazilian government’s measures to control inflation have often included maintaining a tight monetary policy with high interest rates, thereby restricting availability of credit, and reducing economic growth. Inflation, actions to combat inflation and public speculation about possible additional actions also may contribute to economic uncertainty in Brazil and to heightened volatility in the Brazilian securities markets. Brazil may experience high levels of inflation. Increasing prices for petroleum, the depreciation of the real and future governmental measures seeking to maintain the value of the real in relation to the U.S. dollar may trigger increases in inflation in Brazil. Periods of higher inflation may slow the rate of growth of the Brazilian economy, which would lead to reduced demand for our products in Brazil and decreased net revenue. Inflation is also likely to increase some of our costs and expenses, which we may not be able to pass on to our customers and, as a result, may reduce our profit margins and net income. In addition, high inflation generally leads to higher domestic interest rates, and, as a result, the costs of servicing our real-denominated debt may increase, causing our net income to be reduced. Inflation and its effect on domestic interest rates can in addition, lead to reduced liquidity in the domestic capital and lending markets, which could adversely affect our ability to refinance our indebtedness in those markets. Any decline in our net revenue or net income and any deterioration in our financial condition would also likely lead to a decline in the market price of our securities, including class A preferred shares and the ADSs. 44 Table of Contents Fluctuations or changes in, or the replacement of, interest rates could impact the cost of servicing our debt or reduce our financial revenue, affecting our financial performance. Our financial expenses are affected by changes in the interest rates that apply to our floating rate debt. As of December 31, 2025, we had, among other debt obligations: · R$843 million of loans and financing that were subject to the Interbank Deposit Certificate (Certificado de Depósito Interbancário, or “CDI”), rate; · R$243 million of loans and financing that were subject to the Extended National Consumer Price Index (Índice de Preços ao Consumidor Amplo, or “IPCA”); · R$8,986 million of certain of our loans and financing that were subject to the Secured Overnight Financing Rate (SOFR). The CDI and the IPCA rates have fluctuated significantly in the past in response to the expansion or contraction of the Brazilian economy, inflation, Brazilian government policies and other factors. A significant increase in any of these interest rates could adversely affect our financial expenses and negatively affect our overall financial performance. Any other changes or reforms to the determination or supervision of these interest rates could have an adverse effect on our financial expenses and/or financial revenue and adversely affect our overall financial performance. Brazilian government exchange control policies could increase the cost of servicing our foreign currency-denominated debt, adversely affect our ability to make payments under our foreign currency-denominated debt obligations and impair our liquidity. The purchase and sale of foreign currency in Brazil is subject to governmental control. The current laws and regulations governing the Brazilian foreign exchange system allow the purchase and sale of foreign currency and the international transfer of reais by any person or legal entity, regardless of the amount, subject to certain regulatory procedures. Many factors could cause the Brazilian government to institute more restrictive exchange control policies, including the extent of Brazil’s foreign currency reserves, the availability of sufficient foreign exchange on the date a payment is due, the size of Brazil’s debt service burden relative to the economy as a whole, Brazil’s policy towards the IMF and political constraints to which Brazil may be subject. A more restrictive policy could increase the cost of servicing, and thereby reduce our ability to pay, our foreign currency-denominated debt obligations and other liabilities. Our foreign-currency debt denominated in U.S. dollars represented an aggregate of 93.7% of our indebtedness on a consolidated basis as of December 31, 2025, including transaction costs and Braskem Idesa Debt. If we fail to make payments under any of these obligations, we will be in default under those obligations, which could reduce our liquidity as well as the market price of our securities, including our class A preferred shares and ADSs. Risks Relating To Mexico Political conditions in Mexico may affect actions or decisions by the Mexican government, including Pemex, Cenagas, CFE and CENACE, which are, respectively, Braskem Idesa’s main suppliers of ethane, a provider of natural gas transportation services, an electricity back-up supplier, and the controller of national grid and dispatches of energy power generators, all of which are Mexican state-owned enterprises or governmental entities subject to political interference and related risks. The Mexican government has exercised, and continues to exercise, significant influence over the Mexican economy. Accordingly, Mexican governmental actions concerning the Mexican economy and state-owned enterprises could have a significant impact on Mexican private sector entities in general and on our operations in particular. We cannot predict the impact that political conditions will have on the Mexican economy or on our operations. We can give no assurances that changes in Mexican federal government policies will not adversely affect our business, financial condition, results of operations and prospects. We currently do not have and do not intend to obtain political risk insurance. 45 Table of Contents Pemex, a state-owned Mexican entity, produces polyethylene and competes in the same commercial market as we do. The Mexican government may intentionally interfere with us and our operations in various ways that limit our commercial competitiveness. According to Pemex’s public disclosure, its production of oil, natural gas and ethane, over which we have no control, has decreased in recent years, and no assurance can be given that there will not be a decrease in the delivery of ethane in the future. Furthermore, our long-term supply agreement to purchase ethane from Pemex could be modified through regulatory means, terminated or jeopardized by them as a result of political pressure to not comply with the agreement, to change the terms of the agreement, expropriation measures, or change in laws regulations by the Mexican government. Any non-compliance, modification, termination or interruption of this supply agreement could have a material adverse effect on the results of our operations or our financial condition. In June 2024, Mexico held presidential, federal and local elections. Claudia Sheinbaum won the presidency and her political party, Movimiento Regeneración Nacional (National Regeneration Movement, or “MORENA”) won a qualified majority in both the Senate and the Chamber of Deputies, as well as most local elections. This majority could allow MORENA to change Mexican policies and regulations in a manner that increases or mitigates adverse effects on our businesses. In light of the allegations of undue payments related to the Ethylene XXI project, the former name of Braskem Idesa during the construction phase, which were originally published in the media in Mexico and were included in the testimony by the former CEO of Pemex to the Office of the Attorney General of Mexico, Braskem S.A., together with Braskem Idesa, in compliance with the standards established by Braskem’s Global Compliance System Policy and Braskem Idesa’s governance guidelines, approved the hiring of an U.S. law firm with proven experience in similar cases to conduct an independent internal investigation of the allegations (the “Investigation”). The investigation was concluded in February 2022 and did not find evidence to support the allegations by the former CEO of Pemex regarding allegedly improper payments in connection with or otherwise related to the Ethylene XXI project. Mexico has experienced adverse economic conditions, which may adversely affect our business. In the past, Mexico has experienced several periods of slow or negative economic growth, high inflation, high interest rates, currency devaluation and other economic problems. These problems may worsen or reemerge, as applicable, in the future and could adversely affect our business and ability to service our debt. A worsening of international financial or economic conditions, such as a slowdown in growth or recessionary conditions in Mexico’s trading partners, including the United States, or the emergence of a new financial crisis, could have adverse effects on the Mexican economy, our financial condition and our ability to service our debt. Changes in U.S. tariff policy may have implications for Mexico, given the high degree of trade and supply chain integration between the two economies. Higher tariffs could reduce the competitiveness of Mexican exports, particularly in manufacturing sectors closely linked to the U.S. market, while increasing uncertainty for investment and trade flows. Decreases in the growth rate of the Mexican economy, periods of negative growth or reductions in disposable income may result in lower demand for our products. The Mexican government recently cut spending in response to an austerity, and it may further cut spending in the future. These cuts could adversely affect the Mexican economy and, consequently, our business, financial condition, operating results and prospects. In addition, there can be no assurance that the recent Mexican sovereign debt rating downgrades will not adversely affect our business, financial condition or results of operations. 46 Table of Contents Our revenues are subject to risk of loss from unfavorable political and diplomatic developments, social instability, and changes in governmental policies, including expropriation, nationalization, international ownership legislation, interest-rate caps and tax policies. As a result, the actions of the Mexican government concerning the economy and regulating certain industries could have a significant effect on Mexican private sector entities, including us, and on market conditions, prices and returns on Mexican securities, including our securities. A renegotiation of commercial treaties or changes in foreign policy among Mexico, Canada and the United States may negatively affect our business, financial condition, results of operations and prospects. Due to the USMCA and its predecessor, the North American Free Trade Agreement (“NAFTA”), Mexico’s economic conditions have become more closely linked to those of the United States. Adverse economic conditions in the United States could significantly impact the Mexican economy and, consequently, our business. The long-term effects of potential changes tothe USMCA on our operations remain uncertain. Changes in United States trade policy with respect to Mexico could either mitigate or exacerbate these impacts. Increasing immigration policy tensions between the United States and Mexico may also negatively influence United States trade policy. Such changes could affect imports and exports between Mexico and the United States, impacting the economies of both countries and the companies we do business with, potentially harming our business, financial condition, and operations. The USMCA is effective for 16 years from its entry into force, with the possibility of extension. On July 1, 2026, the parties will meet to decide whether to extend or terminate the agreement. Any decision to modify, withdraw, or not extend the USMCA could negatively affect trade between Mexico and the United States, impacting the economies of both countries and our business. In July 2022, the United States and Canada requested dispute settlement consultations with Mexico under the USMCA, arguing potential discriminatory policies against United States and Canadian companies in favor of Mexico’s state-owned electrical utility (CFE) and state-owned oil and gas company Pemex. In October 2022, the three countries agreed to extend such period and in December 2022, they published a working outline to solve the pending issues and continue the consultations. In March 2025, the American Petroleum Institute sent a letter to the United States government denouncing what they consider “unfair practices” in the fuel trade by favoring Pemex. The letter urges the U.S. government to escalate disputes as part of preparations for the 2026 USMCA review. If disagreements persist, the United States or Canada could request an independent dispute settlement panel under the USMCA. Such outcome and any retaliatory tariffs against Mexico could adversely affect our business, results of operations and financial condition. On January 20, 2025, the new United States administration issued the America First Trade Policy, which directed the United States Trade Representative (“USTR”) to commence a public consultation process with respect to the USMCA in preparation for the July 2026 review. On September 16, 2025, the USTR issued a request for public comments on the operation of the USMCA. The USTR also held a public hearing on December 3-5, 2025. The USTR is required to assess the impact of the USMCA on American businesses and make recommendations to the President regarding the United States’ participation in the agreement. On December 16 and 17, 2025, USTR Jamieson Greer reported to certain Congressional Committees on the USTR’s assessment of the operation of USMCA and the upcoming review. USTR Greer stated that "the shortcomings of USMCA are such that a rubberstamp of the Agreement is not in the national interest" and indicated that the nature of the joint review will depend on the "successful resolution" of various bilateral and trilateral issues. Since 2003, Mexican petrochemical exports to the United States have enjoyed zero tariffs under NAFTA and now the USMCA. Any changes to this arrangement through changes to the USMCA or otherwise, could negatively impact the Mexican economy, reducing trade and investment, and adversely affecting our business. Political events in Mexico could affect the Mexican economic policy and our business, financial condition and results of operations. Political circumstances in Mexico may significantly affect Mexican economic policies, which could affect our operations. Significant changes in laws, public policies and/or regulations, or the use of public referendums (consultas populares) could affect Mexico’s political and economic situation, which could, in turn, adversely affect our business. We cannot provide any assurances that political developments in Mexico, over which we have no control, will not have an adverse effect on our business, results of operations, financial condition and prospects. 47 Table of Contents In general, changes that may be made to the existing legal framework, as well as the impact of new regulations, may result in increased costs to us or our customers and may require us to amend existing permits, secure additional permits to operate natural gas, ethane or render our services, or take additional measures to secure permits for our projects. Specifically, Mexican tax legislation is subject to continuous change, and we cannot assure you that the Mexican government will maintain existing political, social, economic or other policies or that such changes would not have a material adverse effect on our business, financial condition, results of operations and prospects. We depend on ethane supplied by Pemex in Mexico. We currently source a significant portion of our supply of ethane, which is the primary feedstock used in our polyethylene production process, from Pemex at prices that reference the Mont Belvieu ethane reference price, a U.S. dollar-based international reference price. As a result, our production volumes, net revenue, and profit margins would likely decrease and materially adversely affect our overall financial performance in case one or more of the following events occur: · significant damage to Pemex’s gas processing centers or to any of the pipelines connecting our complex to Pemex ’s facilities, whether as a consequence of an accident, natural disaster, fire, or otherwise; · any strategic plan for Pemex including but not limited to the reactivation of its ethane derivatives plants in Coatzacoalcos, Veracruz, decreasing the volume of ethane delivered by Pemex to Braskem Idesa; · any further decrease in the volume of ethane currently being delivered by Pemex to our petrochemical complex; · any dispute with Pemex, related to the ethane supply agreement, including the non-recognition or non-payment of shortfall penalties and the decrease or failure to supply the contracted volume of ethane; · any material default by us or by Pemex to supply/receive ethane in the contractually agreed volumes or qualities under the ethane supply agreement; · any material breach or termination by Pemex or by us of the ethane supply agreement, or any material breach or termination by other Mexican state-owned companies of related supply (including those for the transportation of supplies) agreements. As of the date of this annual report, the term has been extended through February 2026 or until the ethane import terminal is constructed, commissioned and commercially operational; or · delays in the availability of ethane of acceptable quality, or our inability to obtain acceptable ethane in the quantities and quality that we need, or at all, or at reasonable prices. Under the ethane supply agreement with Pemex, if Pemex fails to deliver the contracted minimum daily volume during a given quarter, it may offset this shortfall by delivering additional quantities of ethane during the two immediately subsequent quarters. If it does not do so, Pemex will be required to pay Braskem Idesa a penalty equivalent to the average price of the ethane that was not delivered in the period in question. On the other hand, if Braskem Idesa fails to purchase the contracted minimum daily volume, we may be able to offset this deficit by purchasing additional amounts of ethane during the two immediately subsequent quarters. If it does not do so, Braskem Idesa will be required to pay a penalty to Pemex equivalent to the average price of ethane that was not purchased during the period in question. 48 Table of Contents Furthermore, the ethane supply agreement could also be impacted by changes in laws and regulations, terminated or modified by Pemex as a result of political pressure or be subject to expropriation or other adverse measures by the Mexican government or government entities. Braskem Idesa may also renegotiate the terms of the ethane supply agreement, voluntarily or as a result of changes in laws and regulations, or otherwise. The provisions for early termination by Pemex under the Ethane Supply Agreement include: (i) failure by Braskem Idesa to pay that continues for more than six months after notice; or (ii) an emergency stoppage in operations or force majeure event due to which Braskem Idesa’s insurers consider the complex to be a total loss, or after which Braskem Idesa cannot or does not resume operations for 48 months. If Pemex (i) delivers less than an average of 75% of the agreed volume over a six-month period; (ii) reaches the annual limit in respect of shortfall penalties owed by Pemex to Braskem Idesa and such limit is not waived by Braskem Idesa; or (iii) materially breaches any of its obligations related to the supply of ethane thereunder; Braskem Idesa has the right to notify Pemex through a notice of breach. If such breach continues for more than six months after notice, or an extended period if the parties agree, Braskem Idesa has the right to terminate the ethane supply agreement and require Pemex to repay certain outstanding debt and compensate Braskem and Idesa according to an agreed valuation formula including the repayment of certain of our debt in the form of a put option right under the ethane supply agreement. On September 27, 2021, Braskem Idesa entered into: (i) an amendment to the ethane supply agreement (the “amendment to the ethane supply agreement”) with Pemex with presence of Pemex Exploración y Producción to settle certain prior contractual outstanding issues; and (ii) an agreement with Pemex, Pemex Logística with presence of other Mexican government entities, establishing certain support measures to the project to build an ethane import terminal with the capacity to meet all of Braskem Idesa’s feedstock requirements (the “Ethane Import Terminal Agreement”). The amendment to the ethane supply agreement changed the minimum volume commitment to 30,000 barrels per day until February 2025, and such term may be extended in the event of a delay of obtaining permits not attributable to Braskem Idesa or TQPM (Terminal Química Puerto Mexico, S.A.P.I.). As of February 9, 2026, the contractual volume commitment under the amendment to the ethane supply agreement expired, and the parties entered into a right of first refusal arrangement in favor of Braskem Idesa, without any minimum volume obligation The amendment to the ethane supply agreement also gave Braskem Idesa the preemptive right to acquire all of the ethane that Pemex has available and has not consumed in its own production process until 2045 at international benchmark prices. The terminal project is designed to complement the ethane supply in Mexico and enables Braskem Idesa to operate at full capacity by accessing new feedstock sources. Braskem Idesa and its operations in Mexico, including agreements entered into with state-owned or state-controlled entities, are subject to political interference by the Mexican government, which may lead to the termination or repudiation of certain contractual relationships and interference on Braskem Idesa’s operations that may materially and adversely affect us. Any termination, cancellation or modification of the ethane supply agreement or reduction in the amount of shortfall penalties owed to us by Pemex for any other reason, could have an adverse effect on our results of operations and financial position. We depend on services and products supplied by a Mexican state-owned company. Braskem Idesa has entered into agreements with Mexican state-owned companies for the transportation of natural gas and water supply, among others. Any political interference by the Mexican government, termination, cancelation, modification or failure to renew such agreements could have an adverse effect on our business, results of operations and financial condition. 49 Table of Contents Furthermore, such agreements could also be impacted as a result of changes in laws and regulations, terminated or modified as a result of political pressure, or be subject to expropriation or other adverse measures by the Mexican government or government entities. We may also renegotiate the terms of such agreements voluntarily or as a result of changes in laws and regulations or otherwise. We may face unforeseen challenges in the operation of our Mexico Complex, which could result in this business unit failing to provide expected benefits to us. To develop the Mexican business unit, Braskem Idesa invested significant capital and incurred significant debt. Our ability to achieve the strategic objectives of this business unit and serve the debt incurred by it depends largely on its successful operation. Factors that could affect the operation of this business unit include: · any potential restructuring or creditor protection measures that may be taken as a result of ongoing discussions with its creditors; · the inability of payment of its debt, including the recent defaults in the 2029 and 2032 bonds; · general economic, political and business conditions in Mexico and worldwide; · global demand for, and supply balance of, PE, impacting spreads in the international market; · the occurrence of unforeseen technical and mechanical difficulties that may interrupt production or lead to unexpected downtime of the Mexico Complex’s plants; · any material default by Pemex under the ethane supply agreement; · any termination, cancelation or modification of the ethane supply agreement for any other reason; · the failure to renew any material agreement with Mexican state-owned companies; · any material supply chain disruptions including related to ethane, that can negatively impact Braskem Idesa business; · an unstable and non-continuous supply (including the transportation of supplies) of ethane, natural gas and other inputs, including energy and water; and · increased competition from domestic or foreign competitors and/or the emergence of new domestic or foreign competitors. In the first quarter of 2021, Braskem Idesa entered into a natural gas transport service agreement with Cenagas for a term of 15 years. Following the execution of this agreement by Braskem Idesa, it resumed receiving natural gas transportation services from Cenagas, which had been unilaterally terminated by Cenagas in December 2020. On September 27, 2021, Braskem Idesa signed the following documents: (i) an amendment to the ethane supply agreement with Pemex revising certain of its terms (“Amendment”); and (ii) an agreement with Pemex and other government entities that establishes support measures for the project to build an ethane import terminal, with the capacity to meet all of Braskem Idesa’s ethane needs. The Amendment changes the minimum volume commitment to 30,000 barrels per day until February 2025, provided that such term may be extended in the event of a delay of obtaining permits not attributable to Braskem Idesa or to Terminal Química Puerto Mexico, S.A.P.I. (“TQPM”). The term was extended until February 2026 or until the ethane import terminal is constructed, commissioned and commercially operational. The Amendment also gives Braskem Idesa the preemptive right to acquire all the ethane that PEMEX has available and has not consumed in its own production process until 2045, at international benchmark prices. As of February 9, 2026, the contractual volume commitment under the Amendment expired, and the parties entered into a right of first refusal arrangement in favor of Braskem Idesa, without any minimum volume obligation. 50 Table of Contents In 2021, Braskem Idesa constituted the TQPM, a company created to be responsible for the construction and operation of the ethane terminal. In June 2022, Braskem Idesa announced the sale of 50% of TQPM’s stake to Advario B.V. (“Advario”). The TQPM ethane import terminal was designed to have a capacity of 80,000 daily barrels, providing conditions for Braskem Idesa to import all of the raw material it requires. In October 2023, with the support of its shareholders, Braskem Idesa and Advario, TQPM entered into a syndicated project finance loan agreement in the principal amount of R$1,975 million (US$408 million) with a 5 (five) year short-term loan deal with standard guarantees for transactions of this type. The project financing taken by TQPM for the construction of the ethane import terminal in Mexico is also guaranteed by an Equity Support Agreement provided by the Company that, as of the end of December 2025, covers 50% of the financing balance of TQPM, with the remaining 50% guaranteed by the other TQPM shareholder until the project perfection collateral date (which includes the authorization from the local energy regulator – CRE/CNE – to pledge certain assets of TQPM to the syndicated lenders). After reaching such milestone, the Company is committed to provide support covering 100% of the monthly payments for the offtake agreement entered by Braskem Idesa and TQPM up to the outstanding amount of TQPM financing. Any significant interruption in the Mexico Complex operations, including due to financial condition or a restructuring, creditor protection measure or similar transaction, could hinder or prevent the implementation of Braskem Idesa business plan as originally conceived, and result in revenue and net income below original expectations and could impact the Company’s financial condition, including the commitment to provide capital to TQPM. Further, any material adverse effect on the financial condition or results of operations of the Mexican Complex may adversely impact Company’s financial condition and results of its operations. See “—Braskem Idesa is currently assessing alternatives to optimize its capital structure, and the outcome of this process, including any potential restructuring or creditor protection measures, is uncertain and may adversely affect the Company and its stakeholders.” and “Payments on Braskem’s guarantees are junior to Braskem’s secured debt obligations and effectively junior to the debt obligations of Braskem’s subsidiaries and jointly controlled companies.” We source part of our ethane feedstock from Pemex in Mexico, which we expect to be our primary main source of ethane until the Ethane Import Terminal is operational. We currently source part of our supply of ethane, which is the primary feedstock used in our polyethylene production process, from Pemex. Pursuant to the Amended ESA, ethane prices negotiated under such an agreement are referenced to the Mont Belvieu ethane reference price, which is a U.S. dollar-based international reference price. As a result, in case one or more of the following events occurs, our production volumes, net revenue and profit margins would likely decrease, materially adversely affecting our overall financial performance: · significant damage to Pemex’s gas processing centers or to any of the pipelines connecting our complex to Pemex’s facilities, whether as a consequence of an accident, natural disaster, fire or otherwise; · any further decrease in the amount of ethane currently being delivered by Pemex to our petrochemical complex; · any dispute with Pemex (which engages in exploration and production activities) related to the Amended ESA, including the non-recognition or non-payment of shortfall penalties and the decrease or failure to supply the contracted volume of ethane; · any material default by us or by Pemex to supply ethane in the contractually agreed volumes or qualities negotiated under the ESA; · any repudiation or termination by Pemex or by us of the Amended ESA, or any repudiation or termination by other Mexican state-owned companies of related supply (including those for the transportation of supplies) agreements, such as Cenagas (Centro Nacional de Control del Gas Natural); or 51 Table of Contents · delays in the availability of ethane of acceptable quality, or our inability to obtain acceptable ethane in the quantities and quality that we need, or at all, or at reasonable prices. As provided in the Amended ESA, any daily volume rejected by us must be purchased in installments in subsequent deliveries until the deficit has been resolved, and the same mechanics apply to Pemex delivery obligations. If Pemex delivers to us less than the volumes required under the ESA and fails to compensate for the shortfall in subsequent deliveries, it needs to pay compensation for shortfall penalties to us. Furthermore, the Amended ESA could also be impacted by changes in laws and regulations, terminated or repudiated by Pemex as a result of political pressure or be subject to expropriation or other adverse measures by the Mexican government or government entities. We may also renegotiate the terms of the Amended ESA, voluntarily or as a result of changes in laws and regulations, or otherwise. The provisions for early termination by Pemex under the Amended ESA include: (i) our failure to pay that continues for more than six months after notice; or (ii) an emergency stoppage in operations or force majeure event due to which our insurers consider the petrochemical complex to be a total loss, or after which we cannot or do not resume operations for 48 months. Delays in the availability of ethane of acceptable quality, or our inability to obtain acceptable ethane in the quantities and quality that we need or at all, or at reasonable prices, have in the past and would in the future have a material adverse effect on our business, results of operations and financial condition. We may be unable to operate the Mexican Complex at full capacity or at all if one or more of our sources of ethane is disrupted. We diversified our sources of feedstock supply with the Fast-Track Solution (or “Fast Track” ), and we have increased our import capacity by adding additional discharge stations, and we have increased further with the Ethane Import Terminal start of operation by 2025. In addition, we cannot guarantee that we will be able to import ethane at current market prices, which could also adversely affect our business, results of operations and financial condition. The performance of the for the importation of ethane, including Fast-Track Solution and the Ethane Import Terminal, may involve significant risks and uncertainties, such as: · failure to obtain or maintain requisite approvals and permits from the applicable regulators and governmental entities; · failure of equipment involved with performance of Fast Track and/or Ethane Import Terminal; · failure or accidents related to trucks that transport ethane to the Mexican Complex; · failure to achieve expected operational results; · no long-term contracted supply for ethane that will cover needs of Mexican Complex, which exposes BI to volatility in ethane prices; · unanticipated liabilities; or · failure of vessels to deliver cryogenic ethane at the port in the city of Coatzacoalcos. The operation of existing plants and any future projects we are able to complete involves many risks, including, among others, the potential for unforeseen design flaws, engineering challenges, equipment failures or trucks accidents or the breakdown for other reasons of the import facilities; labor disputes; fuel interruption; environmental contamination; and operating performance below expected levels. In addition, weather-related incidents and other natural disasters, pandemics, cyber or other attacks by third parties and other similar events can disrupt storage, transmission and distribution systems and have other impacts than those that we discuss in this section. The occurrence of any of these events could lead to our plants being idle for an extended period of time or our plants operating below expected capacity levels, which may result in lost revenues or increased expenses, including higher maintenance costs and penalties. Any such occurrence could materially adversely affect our businesses, financial condition, cash flows, results of operations and/or prospects. 52 Table of Contents We depend on regulatory authorizations to import ethane for our production activities in México We currently import a significant portion of our ethane supply, which is the primary feedstock used in our polyethylene production process in Mexico. Our ethane import operations depend on two critical Mexican regulatory authorizations: (i) the Authorization for Customs Clearance at a Location Other Than the Authorized Port of Entry (Autorización para el despacho en lugar distinto al autorizado, “LDA”), regulated by the Tax Administration Service (SAT) and the Central Customs Authority and subject to requirements applicable to entities involved in hydrocarbons, petrochemicals and related products; and (ii) authorizations regulated by the Ministry of Energy (“SENER”) to import ethane. On November 6, 2023, SENER amended the applicable framework to subject ethane and certain other raw materials to enhanced import permitting requirements, which may result in delays in permit processing timelines. Terminal Química Puerto México (“TQPM”) obtained the required LDA authorization on December 17, 2025, with a three-year validity period, and Braskem Idesa obtained the required SENER authorization to import ethane on December 4, 2025, with a one-year validity period. Although TQPM and we expect to seek renewals in accordance with applicable timelines, renewal remains subject to regulatory review and discretion and may depend on continued compliance with evolving requirements as well as the completeness and timeliness of the renewal submissions. Failure by us or our contractors to obtain, renew, or comply with either authorization could increase costs, cause operational delays, or result in the suspension of import operations and potentially production activities, any of which. The development of the Ethane Import Terminal may not be successful and may not commence operation as scheduled, be completed within budget or operate at expected levels, which could have a material adverse effect on our businesses, financial condition, cash flows, results of operations and/or prospects. We continue to develop the Ethane Import Terminal. The development, construction and operation of this project involves numerous risks. We may be required to spend significant sums for permitting, fuel supply, infrastructure development, legal and other expenses. If the Ethane Import Terminal is not completed: (i) we may have to impair or write off amounts that we have invested in the development of the Ethane Import Terminal and never receive any return on these preliminary investments; and (ii) could result in a material adverse effect to the operation of our Mexico Complex. Success in developing the Ethane Import Terminal is contingent upon, among other things: · our financial condition and cash flows and may be influenced by a number of external factors outside our control, including the global economy and global energy and financial markets; · any dispute, material default or termination of the engineering, procurement and construction agreement (“TQPM EPC Agreement”), including its renegotiation may result in failures to meet specified deadlines with respect to the Ethane Import Terminal; · any dispute, material default, termination or failure under the Shareholder Agreement with Advario; · timely receipt of required governmental permits, licenses and other authorizations, including any required authorizations to import and store ethane, that do not impose material conditions and are otherwise granted under terms we find reasonable, as well as maintenance of these authorizations; · our contractors and other counterparties’ willingness and financial or other ability to fulfill their contractual commitments; · timely, satisfactory and on-budget completion of construction, which could be negatively affected by engineering problems, adverse weather conditions or other natural disasters, pandemics, cyber or other attacks by third parties, work stoppages, equipment unavailability, contractor performance shortfalls and a variety of other factors; 53 Table of Contents · the existence of hidden defects or inherited environmental liabilities; or · fast and cost-effective resolution of any litigation or unsettled property rights affecting the Ethane Import Terminal. Any failures with respect to the above factors or other factors material to the Ethane Import Terminal could involve significant additional costs to us and otherwise materially adversely affect the successful completion of the Ethane Import Terminal. If we are unable to complete the Ethane Import Terminal, if we experience substantial delays, or if construction, financing or other project costs exceed our estimated budgets and we are required to make additional capital contributions, our businesses, financial condition, cash flows, results of operations and/or prospects could be materially adversely affected. The Ethane Import Terminal started in 2025. The overall investment expected to build such terminal was R$3,592 million (US$580 million) including VAT and financing costs, the expected investment without VAT and financing costs was R$2,762 million (US$446 million). Risks Relating To Our Equity And Debt Securities Our financial statements as of and for the year ended December 31, 2025 contains a footnote related to a substantial doubt about our ability to continue as going concern. The consolidated financial statements included in this Annual Report have been prepared on a going concern basis of accounting, which contemplates continuity of operations, realization of assets and satisfaction of liabilities and commitments in the normal course of business. However, as discussed in our audited consolidated financial statements, there is substantial doubt about our ability to continue as going concern The Company comprehensively evaluated the internal and external factors capable of potentially impacting the going concern assumption. Based on the information available and the projections of the approved business plan, we identified a high level of cash usage over the analyzed horizon, considering both the existing cash balances and the projected inflows from the operating cycle. Key elements considered include: · The prolonged downturn cycle in the petrochemical industry, with structurally compressed spreads; · Cash consumption associated with debt service, particularly recurring interest payments; · Cash requirements related to the obligations arising from the Geological Event in Alagoas; · Cash needs for the maintenance of operating assets, essential for ensuring operational continuity and safety; · Credit rating downgrade; and · Maturity of the US$1.0 billion stand-by facility in December 2026, requiring a significant cash outflow, if not renewed. These factors, as reflected in the approved business plan, indicate increasing pressure on liquidity and guide management’s actions aimed at continuously adjusting the Company’s financial position to the current challenges faced by the global chemical industry. Among the initiatives currently under development, the planned restructuring of our capital structure is noteworthy, as it depends on variables outside the Company’s exclusive control. The assessment of capital structure restructuring began in 2025 and in September 2025 the Company disclosed to the market the engagement of specialized financial and legal advisors to support a comprehensive diagnosis of the available economic-financial options, with a focus on strengthening liquidity in the capital structure. In the course of this assessment, the Company, with assistance of its advisors, is evaluating a range of strategic and financial alternatives, which may include, among others, potential measures for the protection of the Company against creditors. As of the date of this Annual Report, no decision has been made regarding which alternative, or combination of alternatives, may ultimately be implemented, and there can be no assurance as to the timing, feasibility or outcome of this process. Any restructuring or similar transaction, if implemented, is expected to have a material adverse effect on the Company’s financial condition, liquidity, results of operations, capital structure, access to financing, relationships with creditors, suppliers and other stakeholders, as well as on the value and trading price of the Company’s equity and debt securities. If we are unable to continue as a going concern, we may have to liquidate our assets and may receive less than the value at which those assets are carried on our audited consolidated financial statements, and it is likely that investors will lose all or part of their investment. In addition, the uncertainty associated with this ongoing process may negatively impact the Company’s business operations and strategic planning, and it requires as significant amount of time of management. The implementation of any such measures would be subject to a variety of factors, many of which are beyond the Company’s control, including market conditions, creditor engagement, shareholders and judicial approvals and other external considerations. 54 Table of Contents The Company is currently assessing alternatives to optimize its capital structure, and the outcome of this process, including any potential restructuring or creditor protection measures, is uncertain and is expected to adversely affect the Company and its stakeholders. As disclosed in the material fact dated September 26, 2025, the Company engaged financial and legal advisors to assist in the preparation of a comprehensive assessment of strategic and financial alternatives to optimize its capital structure. As of the date hereof, this assessment remains ongoing, and the Company, together with its advisors, has been making progress toward the formulation of a comprehensive capital structure plan, including negotiations with advisors representing Company’s financial creditors. Please see the Company’s consolidated financial statements as of and for the year ended December 31, 2025 included in this Annual Report. In the course of this assessment, the Company, with the assistance of its advisors, is evaluating a range of strategic and financial alternatives, which may include, among others, potential measures for the protection of the Company against creditors. As of the date of this Annual Report, no decision has been made regarding which alternative, or combination of alternatives, may ultimately be implemented, and there can be no assurance as to the timing, feasibility or outcome of this process. Any restructuring, credit protection measure or similar transaction, if implemented, is expected to have a material adverse effect on the Company’s financial condition, liquidity, results of operations, capital structure, access to financing, relationships with creditors and other stakeholders, as well as on the value and trading price of the Company’s equity and debt securities. In addition, the uncertainty associated with this ongoing process may negatively impact Company’s business operations and strategic planning. The implementation of any such measures would be subject to a variety of factors, many of which are beyond the Company’s control, including market conditions, creditors’ engagement, shareholders and judicial approvals and other external considerations. All of the shares issued by Braskem and owned by NSP Inv. are secured for the benefit of certain secured creditors of the Novonor Group. Pursuant to a shares fiduciary assignment agreement (alienação fiduciária em garantia) entered into by the Novonor Group and some non-bankruptcy creditors (credores extraconcursais) on November 27, 2013, as amended on May 13, 2016, July 19, 2016, April 24, 2017, May 23, 2018, March 29, 2019 and October 9, 2020, all ordinary and preferred shares issued by Braskem and held by NSP Inv. are secured for the benefit of certain secured creditors of the Novonor group in connection with certain financing agreements entered into by Novonor and certain of its subsidiaries. In the event that Novonor and certain of its subsidiaries default on such financing agreements, or if such financing agreements are accelerated, or if creditors consolidate the ownership of the shares and dispose them (assuming that Petrobras does not exercise its preemptive rights to acquire such shares) we may be subject to a change of control following statutory, legal and procedural formalities required pursuant to our shareholders’ agreement. A change of control under these circumstances may adversely affect us. On December 15, 2025, we received a correspondence sent by Novonor S.A – Em Recuperação Judicial and Shine I Fundo de Investimento em Direitos Creditórios de Responsabilidade Limitada, represented by its manager Vórtx Capital Gestora De Recursos Ltda. (“FIDC”), advised by IG4 Sol. Ltda., informing about the execution of (i) a definitive binding agreement between the FIDC and the creditor banks of NSP Investimentos S.A. (“NSP Inv.”) and other entities of the group Novonor S.A. – Em Recuperação Judicial (“Grupo Novonor”) to acquire all the credits held by the aforementioned banks against Novonor guaranteed by, among others, fiduciary assignment constituted on the shares issued by the Company held by NSP Inv. (“Transaction”); and (ii) exclusivity agreement with an initial term of sixty (60) days between FIDC and Novonor regarding a potential transaction involving the shares issued by Braskem held by NSP Inv. On March 6, 2026, the Administrative Council for Economic Defense (CADE) General Superintendence (Superintendência Geral) issued a decision (despacho), through which it decided to approve, without restrictions, the Transaction. The foreclosure or sale of our shares held by NSP Inv. - whether in the Novonor Judicial Restructuring Proceedings or agreements entered into within the context of the Novonor Judicial Restructuring Proceedings may result in a change of our control. As we do not have the ability to consent to or otherwise influence or control the Novonor Judicial Restructuring Proceedings or the acquirer of the shares from any such disposal, we may be subject to a change in our corporate control in the foreseeable future. Holders of our class A preferred shares or the ADSs may not receive any dividends or interest on shareholders’ equity. As permitted by Brazilian Corporate Law, our by-laws specify that 25% of our Adjusted Net Income for each fiscal year must be distributed to shareholders as mandatory dividends, or the Mandatory Distribution of Dividends. Under our by-laws, our class A and class B preferred shareholders are entitled to an annual non-cumulative preferential dividend, or the Minimum Preferred Dividend, equal to 6% of their pro rata share of our capital before dividends may be paid to our common shareholders. The Brazilian Corporate Law allows a publicly traded company like ours to not distribute the Mandatory Distribution of Dividends in any particular year if our board of directors informs in connection with an annual shareholders’ meeting that such distributions would be incompatible with our financial condition, provided that such suspension does not affect the Minimum Preferred Dividend, which is still payable to the holders of preferred shares. However, the shareholders, including the holders of our class A preferred shares or the ADSs, may not receive any dividends or interest on shareholders’ equity in any given year if we do not record a profit. The non-payment of dividends may frustrate expectations of cash return on the part of our investors and may lead to a loss in the value of our shares in the market. In addition, according to Law No. 15,270, dated November 26, 2025, the levy of Withholding Income Tax (IRRF) on dividends was established at a 10% rate when paid to beneficiaries resident abroad. It should be noted, however, that the effects of this legislation enter into force only as of January 1, 2026. With regard to Interest on Equity (JCP), Complementary Law No. 224/2025, published on December 26, 2025, increased the IRRF rate applicable to the payment or credit of JCP, raising it from 15% to 17.5%. 55 Table of Contents Our class A preferred shares and the ADSs have limited voting rights and are not entitled to vote to approve corporate transactions, including mergers or consolidations of our Company with other companies, or the declaration of dividends. Under the Brazilian Corporate Law and our by-laws, holders of our class A preferred shares and, consequently, the ADSs underlying these shares are not entitled to vote at meetings of our shareholders, except in very limited circumstances. These limited circumstances directly relate to key rights of the holders of class A preferred shares, such as modifying basic terms of our class A preferred shares or creating a new class of preferred shares with superior rights. Holders of preferred shares without voting rights are entitled to elect one member and his or her respective alternate to our board of directors and our fiscal council, depending on specific requirements provided in the Brazilian Corporate Law. Holders of our class A preferred shares and the ADSs are not entitled to vote to approve corporate transactions, including mergers or consolidations of our Company with other companies, or the declaration of dividends. However, if we do not pay dividends for three consecutive years, holders of our class A preferred shares and the ADSs will be granted voting rights. Holders of the ADSs may find it difficult to exercise even their limited voting rights at our shareholders’ meetings. Under Brazilian Corporate Law, only shareholders registered as such in our corporate books may attend our shareholders’ meetings. All class A preferred shares underlying the ADSs are registered in the name of the depositary. ADS holders may exercise the limited voting rights with respect to our class A preferred shares represented by the ADSs only in accordance with the deposit agreement relating to the ADSs, which provides that voting rights are only available to ADS holders at our discretion. There are practical limitations upon the ability of ADS holders to exercise their voting rights due to the additional steps involved in communicating with ADS holders. For example, we are required to publish a notice of our shareholders’ meetings in certain newspapers in Brazil. To the extent that holders of our class A preferred shares are entitled to vote at a shareholders’ meeting, they will be able to exercise their voting rights by attending the meeting in person, voting by proxy or by remote voting, if applicable. By contrast, holders of the ADSs will receive notice of a shareholders’ meeting by mail from the depositary following our notice to the ADS depository requesting the ADS depository to do so. To exercise their voting rights, ADS holders must instruct the depositary on a timely basis. This noticed voting process will take longer for ADS holders than for holders of class A preferred shares. If it fails to receive timely voting instructions for all or part of the ADSs, the depositary will assume that the holders of those ADSs are instructing it to give a discretionary proxy to a person designated by us to vote their ADSs, except in limited circumstances. In the limited circumstances in which holders of the ADSs have voting rights, they may not receive the voting materials in time to instruct the depositary to vote the class A preferred shares underlying their ADSs. In addition, the depositary and its agents are not responsible for failing to carry out the voting instructions of the holders of the ADSs or for the manner of carrying out those voting instructions. Accordingly, holders of the ADSs may not be able to exercise their voting rights, and they will have no recourse if the class A preferred shares underlying their ADSs are not voted as requested. If holders of the ADSs exchange them for class A preferred shares, they may risk temporarily losing, or being limited in, the ability to remit foreign currency abroad and certain Brazilian tax advantages. The Brazilian custodian for the preferred shares underlying the ADSs must obtain an electronic registration number with the Central Bank to allow the depositary to remit U.S. dollars abroad. ADS holders benefit from the electronic certificate of foreign capital registration from the Central Bank obtained by the custodian for the depositary, which permits it to convert dividends and other distributions with respect to the class A preferred shares into U.S. dollars and remit the proceeds of such conversion abroad. If holders of the ADSs decide to exchange them for the underlying preferred shares, they will only be entitled to rely on the custodian’s certificate of registration with the Central Bank for five business days after the date of the exchange. Thereafter, they will be unable to remit U.S. dollars abroad unless they obtain a new electronic certificate of foreign capital registration in connection with the preferred shares, which may result in expenses and may cause delays in receiving distributions. Also, if holders of the ADSs that exchange the ADSs for our Class A preferred shares do not qualify under the foreign investment regulations, they will generally be subject to less favorable tax treatment of dividends and distribution on, and the proceeds from any sale of, our preferred shares. 56 Table of Contents Restrictions on the movement of capital out of Brazil may impair the ability of holders of our shares, ADSs and debt securities to receive payments on their respective obligations or guarantees and may restrict our ability to make payments in U.S. dollars. In the past, the Brazilian economy has experienced balance of payment deficits and shortages in foreign exchange reserves, and the government has responded by restricting the ability of Brazilian or foreign persons or entities to convert reais into foreign currencies. The government may institute a restrictive exchange control policy in the future. Any restrictive exchange control policy could prevent or restrict our access to U.S. dollars, and consequently our ability to meet our U.S. dollar obligations under our shares, ADSs and the guarantees we granted pursuant to our outstanding debt securities and could also have a material adverse effect on our business, financial condition and results of operations. The foreign exchange policy of Brazil may affect the ability of Braskem to make money remittances outside Brazil in respect of our equity securities or debt securities. Under current Brazilian regulations, Brazilian companies are not required to obtain authorization from the Central Bank in order to make payments under guarantees in favor of foreign persons, such as the holders of our shares, ADSs or our outstanding debt securities. We cannot assure you that these regulations will continue to be in force in the event that Braskem is required to perform its payment obligations under its shares, ADSs or the guarantees under our outstanding debt securities. If these regulations or their interpretation are modified and an authorization from the Central Bank is required, Braskem would need to seek an authorization from the Central Bank to transfer the amounts under such obligations out of Brazil or, alternatively, make such payments with funds held by Braskem outside Brazil. We cannot assure you that such an authorization will be obtained or that such funds will be available. If such authorization is not obtained, we may be unable to make payments to holders of our shares, ADSs or the applicable debt securities in foreign currency. If we are unable to obtain the required approvals, if needed for the payment of amounts owed by Braskem through remittances from Brazil, we may have to seek other lawful mechanisms to effect payment of amounts due under the shares, ADSs or debt securities. However, we cannot assure you that other remittance mechanisms will be available in the future, and even if they are available in the future, we cannot assure you that payment on the outstanding debt securities would be possible through such mechanism. Holders of the ADSs may face difficulties in protecting their interests because we are subject to different corporate rules and regulations as a Brazilian company and our shareholders may have fewer and less well-defined rights than under the laws of other jurisdictions, including in a jurisdiction in the United States. Holders of the ADSs are not our direct shareholders and are unable to enforce the rights of shareholders under our by-laws and the Brazilian Corporate Law. Our corporate affairs are governed by our by-laws and the Brazilian Corporate Law, which differ from the legal principles that would apply if we were incorporated in a jurisdiction in the United States, such as the State of Delaware or New York, or elsewhere outside Brazil. Even if a holder of ADSs surrenders its ADSs and becomes a direct shareholder, its rights as a holder of the class A preferred shares underlying the ADSs under the Brazilian Corporate Law to protect its interests relative to actions by our board of directors may be fewer and less well-defined than under the laws of those other jurisdictions. Although insider trading and price manipulation are crimes under Brazilian law and are the subject of continuously evolving regulations promulgated by the Brazilian Securities Commission, or the CVM, the Brazilian securities markets are not as highly regulated and supervised as the U.S. securities markets or the markets in some other jurisdictions. In addition, rules and policies against self-dealing or for preserving shareholder interests may be less well-defined and enforced in Brazil than in the United States and certain other countries, which may put holders of our class A preferred shares and the ADSs at a potential disadvantage when compared to holders of shares of companies incorporated in other jurisdictions. Corporate disclosures also may be less complete or informative than for a public company in the United States or in certain other countries. 57 Table of Contents Holders of the ADSs may face difficulties in serving process on or enforcing judgments against us and other persons. We are a corporation (sociedade por ações) organized under the laws of Brazil, and all of our directors and executive officers and our independent public accountants reside or are based in Brazil. Most of our assets and those of these other persons are located in Brazil. As a result, it may not be possible for holders of the ADSs to effect service of process upon us or these other persons within the United States or other jurisdictions outside Brazil or to enforce against us or these other persons judgments obtained in the United States or other jurisdictions outside Brazil. In addition, because a substantial portion of our assets, and all of our directors and officers reside outside the United States, any judgment obtained in the United States against us or any of our directors or officers may not be collectible within the United States. Because judgments of U.S. courts for civil liabilities based upon the U.S. federal securities laws may only be enforced in Brazil if certain conditions are met, holders may face greater difficulties in protecting their interests in the case of actions by us or our directors or executive officers than would shareholders of a U.S. corporation. Judgments of Brazilian courts enforcing Braskem’s obligations under our equity securities, debt securities or related guarantees would be payable only in reais. If proceedings are brought in the courts of Brazil seeking to enforce our obligations under our equity securities, ADSs, the guarantees under our outstanding debt securities or our other indebtedness, we would not be required to discharge our obligations in a currency other than reais. Any judgment obtained against us in Brazilian courts in respect of any payment obligations under such equity securities, ADSs, guarantees or other indebtedness would be expressed in reais. We cannot assure you that this amount in reais will afford the holders of the shares, ADSs, notes or our other indebtedness full compensation of the amount sought in any such litigation. Actual or anticipated sales of a substantial number of class A preferred shares could decrease the market prices of our class A preferred shares and the ADSs. Sales of a substantial number of our class A preferred shares could negatively affect the market prices of our class A preferred shares and the ADSs. If substantial sales of shares are made through the securities markets by our controlling shareholder or other class A preferred shares, the market price of our class A preferred shares and, by extension, the ADSs may decrease significantly. As a result, holders of the ADSs may not be able to sell the ADSs at or above the price they paid for them. Holders of the ADSs or class A preferred shares in the United States may not be entitled to the same preemptive rights as Brazilian shareholders have, pursuant to Brazilian legislation, in the subscription of shares resulting from capital increases made by us. Under Brazilian law, if we issue new shares in exchange for cash or assets as part of a capital increase, subject to certain exceptions, we must grant our shareholders preemptive rights at the time of the subscription of shares, corresponding to their respective interest in our share capital, allowing them to maintain their existing shareholding percentage. We may not legally be permitted to allow holders of ADSs or class A preferred shares in the United States to exercise any preemptive rights in any future capital increase unless (1) we file a registration statement for an offering of shares resulting from the capital increase with the SEC, or (2) the offering of shares resulting from the capital increase qualifies for an exemption from the registration requirements of the U.S. Securities Act of 1933, as amended (the “Securities Act”). At the time of any future capital increase, we will evaluate the costs and potential liabilities associated with filing a registration statement for an offering of shares with the SEC and any other factors that we consider important in determining whether to file such a registration statement. We cannot assure the holders of the ADSs or class A preferred shares in the United States that we will file a registration statement with the SEC to allow them to participate in any of our capital increases. As a result, the equity interest of such holders into us may be diluted. 58 Table of Contents Brazilian tax laws may have an adverse impact on the taxes applicable to the disposition of our ADSs and preferred shares. According to Law No. 10,833, of December 29, 2003, if a nonresident of Brazil disposes of assets located in Brazil, the transaction will be subject to taxation in Brazil, even if such disposition occurs outside Brazil or if such disposition is made to another nonresident. Dispositions of our ADSs between nonresidents, however, are currently not subject to taxation in Brazil. Nevertheless, in the event that the concept of “disposition of assets” is interpreted to include the disposition between nonresidents of assets located outside Brazil, this tax law could result in the imposition of withholding taxes in the event of a disposition of our ADSs made between nonresidents of Brazil. Due to the general and broad scope of Law No. 10,833/2003, and the absence of judicial precedent, we are unable to predict whether an interpretation applying such tax laws to dispositions of our ADSs between nonresidents could ultimately prevail in Brazilian courts. The relative volatility and liquidity of the Brazilian securities markets may adversely affect holders of our class A preferred shares and ADSs. The Brazilian securities markets are substantially smaller, less liquid and more volatile than major securities markets in the United States and other jurisdictions and may be regulated differently from the manner in which U.S. investors are accustomed. Factors that may specifically affect the Brazilian equity markets may limit the ability of holders of the ADSs to sell class A preferred shares underlying ADSs at a price and at a time when they wish to do so and, as a result, could negatively impact the market price of the ADSs themselves. Economic developments and investor perceptions of risk in other countries, including both in developed or emerging market economies, may adversely affect the trading price of Brazilian securities, including our common shares and ADSs, as well as any outstanding debt securities. The market value of securities of Brazilian issuers is affected in varying degrees by economic and market conditions in other countries, including in developed countries, such as the United States and certain European countries, and in emerging market countries. Although economic conditions in such countries may differ significantly from economic conditions in Brazil, the reaction of investors to developments in these other countries may have an adverse effect on the market value of securities of Brazilian issuers. The price of shares traded in the Brazilian capital markets, for example, has been historically subject to fluctuation of interest rates in the United States and the variation in the main U.S. stock exchanges. In addition, crisis in other emerging countries may diminish investor interest in securities of Brazilian issuers, including our shares and ADSs and our debt securities. This could adversely affect the market price of our shares, ADSs and outstanding debt securities and could also make it more difficult for us to access capital markets, affecting our ability to finance our operations on acceptable terms. We are exposed to disruption and volatility of global financial markets due to their effects on the economic and financial environment, particularly in Brazil, such as economic downturn, increased unemployment rate, decreased purchasing power of consumers and unavailability of credit. In addition, the market value of securities of Brazilian issuers, including our shares and ADSs and our debt securities. These disruptions or volatility in global financial markets may increase even further the negative effects on the Brazilian economic and financial environment, adversely affecting us. We rely on cash generated from operations and external sources to fund our ongoing capital needs. Our level of indebtedness and cash consumption could adversely affect our liquidity position and ability to raise additional capital to fund our operations, limit our ability to react to changes to general market and economic conditions and changes in our industry, and prevent us from meeting our obligations under our agreements (including financing agreements). We require significant capital to operate our business. In addition, interest payments, the geological event in Alagoas, and capital expenditures for our current business and other business opportunities that we may choose to pursue may also require significant amounts of capital. 59 Table of Contents Since the second half of 2022, our business, financial condition and results of operations have been adversely affected by the deterioration of chemical and petrochemical spreads, mainly due to a combination of a relevant increase in the global supply of chemical and petrochemical products and an expressive decline in growth of global demand. Moreover, the geological event in Alagoas has required us and may continue to require the use of a significant amount of cash to meet settlement and other obligations that have arisen from such event. While we have taken and are continuing to take mitigating measures to improve our business performance and liquidity position, such material and adverse conditions may persist for the foreseeable future or a longer period of time, including due to events that are outside of our control, which in turn could lead to further deterioration of our business, financial condition and results of operations. Further, while the industry outlook may improve in the future, such improvement may not lead to a sufficient recovery of our cash flows to meet our ongoing capital needs. Any continuing adverse effect on our financial condition or the deterioration of our level of indebtedness or our leverage, together with potential negative changes to our ratings and those of our debt securities by the main credit rating agencies, are expected to have certain material consequences to us, including the following: · limit our ability to fulfill our capital needs obligations; · limit our ability to obtain additional financing for working capital, capital expenditures, product development, debt service requirements, business opportunities and general corporate or other purposes; · limit our ability to pay dividends; · limit our ability to adjust to changing market conditions and place us at a competitive disadvantage compared to our competitors that have less debt; and · we may become vulnerable in a general economic downturn and during an extended tight petrochemical cycle. As disclosed in the material facts notice dated September 26, 2025, the Company engaged specialized financial and legal advisors to assist in the preparation of a comprehensive assessment of economic and financial alternatives aimed at optimizing its capital structure. This assessment remains ongoing, and the Company, together with its advisors, has been making structured progress toward the formulation of a comprehensive capital structure plan, including through negotiations with advisors representing the Company’s creditors. Our access to the credit and capital markets, and the pricing of our capital are dependent upon our financial condition, our credit ratings and those of our debt securities from credit rating agencies, and the state of the capital markets generally. If we need further external financing, there can be no assurances that we would be able to incur indebtedness, and it is possible that the cost of any financings could increase significantly, thereby further increasing our expenses. In October 2025, the Company fully the amount of US$1.0 billion (or R$5,502 million), which was available under the stand-by credit facility. The credit facility matures in December 2026. If we are unable to generate sufficient cash flow or raise adequate external financing, our financial condition would be adversely affected, and we could become unable to meet in full our debt service and repayment obligations and, as a result, could be forced to restrict our business and operations. In the event of a default under our credit facilities or any of our outstanding senior notes, we could be required to immediately repay all of our outstanding borrowings, which we may not be able to do. Any event of default under any of our credit arrangements could cause a cross-default or cross-acceleration under many of our other credit agreements and debt instruments. Without waivers from lenders that are a party to those agreements, any such default could have a material adverse effect on our business, financial condition and results of operations. 60 Table of Contents Any downgrade in the ratings of Brazil, our Company or our debt securities would likely result in increased interest and other financial expenses related to our borrowings and debt securities that could reduce our liquidity. Currently, Standard & Poor’s Ratings Group, a division of McGraw Hill, Inc., or Standard & Poor’s, and Fitch Ratings Ltd., or Fitch, maintain our ratings on a global and national basis. On a global basis, our current ratings by : (i) Standard & Poor’s are CCC-with a negative outlook and (ii) Fitch Ratings are CC. Our ratings are lower than the Brazilian sovereign rating by these two main rating agencies. On a national basis, our curent ratings by: (i) Standard & Poor’s are brCCC- with a negative outlook and (ii) Fitch Ratings are CC(bra) with a stable rating outlook. On December 12, 2023, we decided to cancel the corporate credit rating on a global scale issued by the Moody’s Investors Service, Inc., or Moody’s. Our credit rating is sensitive to any change in the Brazilian sovereign credit rating. The credit rating of the Brazilian federal government was maintained in June 2025 at BB by Fitch, and BB by S&P. Any decision by these rating agencies to downgrade the Brazilian sovereign credit rating, our ratings and the ratings of our debt securities in the future would likely result in higher interest rates and other financial expenses related to the loans and debt securities, and the inclusion of financial covenants in the agreements regulating such new debts, which may significantly reduce our ability to raise funds under satisfactory conditions or in the amounts necessary to ensure our liquidity, as well as force us to issue cash collateral as a result of our covenants, or letters of credit to back collaterals given by us. Because Braskem Netherlands Finance B.V. and Braskem America Finance Company have no operations of their own, holders of our outstanding debt securities issued by Braskem Netherlands Finance B.V. or Braskem America Finance Company depend on Braskem to provide Braskem Netherlands Finance B.V., respectively, with sufficient funds to make payments on these debt securities when they become due. Braskem Netherlands Finance B.V., or Braskem Netherlands Finance, an indirect wholly-owned subsidiary of Braskem incorporated under the laws of The Netherlands, and Braskem America Finance Company, a direct wholly-owned subsidiary of Braskem America, and an indirect wholly-owned subsidiary of Braskem, incorporated under the laws of the State of Delaware, have no operations of their own other than the issuing and making of payments on their respective debt securities and other indebtedness, and using the proceeds therefrom as permitted by the agreements governing these issuances, including lending the net proceeds of the debt securities and other indebtedness incurred by Braskem Netherlands Finance and Braskem America Finance Company to Braskem and subsidiaries of Braskem. Accordingly, the ability of Braskem Netherlands Finance and Braskem America Finance Company to pay principal, interest and other amounts due on the outstanding debt securities issued by it and other indebtedness will depend on our financial condition and results of operations and those of our subsidiaries that are debtors of Braskem Netherlands Finance or Braskem America Finance Company, respectively. In the event of an adverse change in our financial condition or results of operations or those of our subsidiaries that are debtors of Braskem Netherlands Finance or Braskem America Finance Company, these entities may be unable to service their indebtedness to Braskem Netherlands Finance or Braskem America Finance Company, as the case may be, which would result in the failure of Braskem Netherlands Finance or Braskem America Finance Company, as the case may be, to have sufficient funds to repay all amounts due on or with respect to the respective outstanding debt securities. Payments on Braskem’s guarantees are junior to Braskem’s secured debt obligations and effectively junior to the debt obligations of Braskem’s subsidiaries and jointly controlled companies. The outstanding debt securities are fully guaranteed by Braskem. The Braskem guarantees constitute senior unsecured obligations of Braskem. The guarantees rank equal in right of payment with all of Braskem’s other existing and future senior unsecured indebtedness. Although the guarantees provide the holders of the debt securities with a direct but unsecured claim on Braskem’s assets and property, payment on the guarantees is subordinated to the secured debt of Braskem to the extent of the assets and property securing such debt. 61 Table of Contents Upon any liquidation or restructuring of Braskem, any right of the holders of the debt securities, through enforcement of Braskem’s guarantees (i) to participate in the assets of Braskem, including the capital stock of its subsidiaries and jointly controlled entities, will be subject to the prior claims of Braskem’s secured creditors, and (ii) to participate in the assets of Braskem’s subsidiaries and jointly controlled entities will be subject to the prior claims of the creditors of such subsidiaries and jointly controlled entities. While the indentures and credit agreements relating to the outstanding debt of Braskem include a covenant limiting the ability of Braskem and its subsidiaries to create liens, this limitation is subject to significant exceptions. As of December 31, 2025, Braskem had (1) consolidated corporate debt, of R$51,821 million (US$9,418 million), and (2) consolidated Braskem Idesa debt related to our Mexico Complex (including TQPM) of R$14,308 million (US$2,600 million). Braskem conducts a portion of its business operations through subsidiaries and jointly controlled companies. In servicing payments to be made on its guarantees of the outstanding debt securities, Braskem may rely, in part, on cash flows from its subsidiaries and jointly controlled companies, mainly in the form of dividend payments. The ability of these subsidiaries and jointly controlled entities to make dividend payments to Braskem will be affected by, among other factors, the obligations of these entities to their creditors, requirements of Brazilian corporate and other laws, and restrictions contained in agreements entered into by or relating to these entities. In the event that these subsidiaries and jointly controlled entities are unable to make dividend payments to Braskem due to insufficient cash flows, Braskem may be required to utilize its own cash flows to service payments. Further, if these subsidiaries and jointly controlled entities are unable to pay their debt, they may become subject to bankruptcy or insolvency proceedings. Any bankruptcy or insolvency proceedings of these subsidiaries and jointly controlled entities may have an adverse effect on our financial condition and results of operations. Braskem’s obligations under the guarantees of the outstanding debt securities are subordinated to certain statutory preferences. Under Brazilian law, Braskem’s obligations under the guarantees of the outstanding debt securities are subordinated to certain statutory preferences. In the event of a liquidation, bankruptcy, or judicial restructuring of Braskem, such statutory preferences, including post-petition claims, claims for salaries, wages, social security, taxes and court fees, and expenses and claims secured by collateral, among others, will have preference over any other claims, including claims by any investor in respect of the guarantees. In such event, enforcement of the guarantees may be unsuccessful, and holders of the outstanding debt securities may be unable to collect amounts due under the outstanding debt securities. Brazilian insolvency laws may be less favorable to holders of our shares, ADSs, and outstanding debt securities than bankruptcy and insolvency laws in other jurisdictions. If we are unable to pay our indebtedness, including our obligations under the shares, ADSs, and guarantees under the outstanding debt securities, then we may become subject to insolvency proceedings in Brazil. The Brazilian insolvency laws currently in effect allow Brazilian companies in a situation of insolvency to be the target of bankruptcy requests by creditors and/or to initiate legal measures aiming to resolve their debts, thus maintaining their activities, preserving value and promoting their social purpose. In cases of bankruptcy decree, payments of the debts must be made in accordance with a legal order provided for by law. In cases of judicial reorganization or a request for ratification of an extrajudicial recovery plan, payments of debts subject to such procedures would be made in accordance with the provisions of the judicial or extrajudicial recovery plan. The insolvency laws of Brazil currently in effect are significantly different from, and may be less favorable to creditors than, those of certain other jurisdictions. For example, holders of our outstanding debt securities may have limited voting rights at creditors’ meetings in the context of a court reorganization proceeding. In addition, any judgment obtained against us in Brazilian courts in respect of any payment obligations under the guarantees normally would be expressed in the real equivalent of the U.S. dollar amount of such sum at the exchange rate in effect: (1) on the date of actual payment; (2) on the date on which such judgment is rendered; or (3) on the date on which collection or enforcement proceedings are started against us. Consequently, in the event of our bankruptcy, all of our debt obligations that are denominated in foreign currency, including the guarantees, will be converted into reais at the prevailing exchange rate on the date of declaration of our bankruptcy by the court. We cannot assure you that such a rate of exchange will afford full compensation of the amount invested in our outstanding debt securities plus accrued interest. 62 Table of Contents Braskem Idesa is currently assessing alternatives to optimize its capital structure, and the outcome of this process, including any potential restructuring or creditor protection measures, is uncertain and is likely adversely affect the Company and its stakeholders. There is substantial doubt as to the ability of Braskem Idesa to continue as going concern. The deterioration of Braskem Idesa’s economic and financial condition is set within an adverse operating environment observed over recent years, primarily characterized by a significant compression of petrochemical spreads, resulting from a prolonged industry downturn, driven by weaker-than-expected global demand and global oversupply, largely attributable to China and the USA, as well as an increase in the reference price of ethane related to the original contract with Braskem Idesa’s local supplier. In addition, Braskem Idesa faced material constraints in access to ethane in Mexico, the main feedstock for its production process, which limited operational flexibility, reduced capacity utilization rates, and increased exposure to import feedstocks with lower economic competitiveness. Taken together, these factors resulted in operating cash generation consistently below the level required to support Braskem Idesa’s existing indebtedness, contributing to liquidity imbalance and an increased financial risk profile. As a result, in September 2025, Braskem Idesa announced that, with the objective of reviewing its current capital structure and liquidity conditions, it had engaged financial and legal advisors (Lazard Inc., Cleary Gottlieb Steen & Hamilton LLP and Sainz Abogados) to support Braskem Idesa in assessing a broad range of economic and financial alternatives for its capital structure. In November 2025, Braskem Idesa defaulted on interest payments related to the bond maturing in 2029. As of December 31, 2025, the outstanding balance of such interest, recorded in current liabilities, amounted to R$230 million (US$42 million). As a result of this non-payment, the full outstanding balance of interest and principal of the bond 2029 may be accelerated by the bondholders, subject to the applicable contractual quorum. Since the decision to accelerate the debt is not under Braskem Idesa’s control, and it does not have the ability to defer these payments for at least 12 months after the reporting date, the balance of this obligation as well as other long-term borrowings that contain cross-default clauses in their contracts were reclassified to current liabilities. In December 2025, Braskem Idesa provided certain holders of the bond 2029 and the bond 2032 (the ad-hoc group or “AHG”) with non-public information in the context of a potential reorganization of its capital structure. After the parties were unable to reach a consensus on the proposal submitted by Braskem Idesa, such information was subsequently disclosed to the market, including the discussion materials and the proposals presented. Additionally, in February 2026, Braskem Idesa announced the non-payment of the interest due on the bond 2032. The bond 2032 has also been reclassified as a current liability. Finally, in light of the context presented, Braskem Idesa remains engaged in negotiations with the AHG, with a view to reorganizing its capital structure through judicial measures (e.g., Chapter 11 under U.S. Law), which is likely to have impacts on the Company and on the shareholding control of Braskem Idesa. These events and conditions indicate that a material uncertainty exists that may cast substantial doubt on Braskem Idesa’s ability to continue as a going concern and equity ownership of Braskem Idesa. A restructuring or similar transaction of Braskem Idesa is likely to be implemented whether or not an agreement is reached with the AHG. Any restructuring or similar transaction is expected to have a material adverse effect on the Company’s reputation, relationships with creditors, suppliers and other stakeholders, as well as on the value and trading price of the Company’s equity and debt securities. A restructuring of Braskem Idesa may also lead to our forfeiture of the equity interest the Company holds in Braskem Idesa, as well claims of Braskem Idesa against the Company to the extent it is identified any credit or asset that Braskem Idesa may hold against the Company. If we are unable to continue as a going concern, we may have to liquidate our assets and may receive less than the value at which those assets are carried on our audited financial statements, and it is likely that investors will lose all or part of their investment. In addition, the uncertainty associated with this ongoing process may negatively impact the Company’s business operations and strategic planning. 63 Table of Contents The implementation of any such measures would be subject to a variety of factors, many of which are beyond Braskem Idesa’s and the Company’s control, including market conditions, creditor engagement, shareholders and judicial approvals and other external considerations.

We are a corporation (sociedade por ações) organized under the laws of Brazil. Our registered office is at Rua Eteno, 1561, Pólo Petroquímico, Camaçari, Bahia, postal code 42810-000, Brazil, and our telephone number at this address is +55 71 3413-2102. Our head office is at Rua Lemos Monteiro, 120 – 24º floor, Butantã, São Paulo, SP, postal code 05501-050, Brazil, and our telephone number at this address is +55 11 3576-9000. We are the largest producer of plastics in the Americas, based on the annual production capacity of our plants, according to CMA. We operate in the first and second generations of the petrochemical industry, with integrated operations in Brazil and Mexico. In the United States and Europe, our operations are directly supplied with raw material for the second generation by non-integrated suppliers. Through fossil, renewable, and recycled raw materials, we offer a broad portfolio of chemicals and plastics transformed by our customers in more than 70 countries into applications such as food packaging, household furniture, industrial and automotive components, paints and coatings, among others. We are the global leader in PE I’m green™ bio-based production, according to CMA, and benefit from our industrial footprint in Brazil, which is one of the largest ethanol producers in the world. Our History In July 2001, in partnership with the Mariani Group, Novonor (formerly called Odebrecht S.A.) acquired a controlling interest in Copene (Camaçari Petrochemical Complex) in the state of Bahia. In August 2002, with the merger of Copene with five other companies, Braskem was created. Between 2006 and 2010, we invested in the consolidation of the petrochemical industry in Brazil. Two relevant steps in this stage of our growth were conducted in partnership with Petrobras, which led to the increase of their stake in the Company: the consolidation of our Southern Complex, which was executed between March 2007 and May 2009; and the acquisition of Quattor, which owned significant assets in São Paulo and Rio de Janeiro, announced in January 2010. This consolidation strengthened the Brazilian petrochemical sector and allowed us to reach a new level of scale to face the challenges of the international market. In February 2010 we began our internationalization strategy, when we announced the acquisition of the PP assets of Sunoco Chemicals and in July 2011, we announced the acquisition of Dow Chemical’s PP business, including four plants (two plants in the United States and two plants in Germany). This acquisition represented an important step in the consolidation of our growth strategy in the Americas, consolidating us as the largest producer of polypropylene in the United States and strengthening our position in Europe. In April 2016, our subsidiary Braskem Idesa, a joint venture with the Mexican Idesa group, reached an important milestone with the production of the first batch of PE in the Mexico petrochemical complex, strengthening our internationalization strategy and ensuring greater access to competitive gas-based feedstocks. In September 2020, we successfully started the greenfield Project Delta to produce PP in La Porte, Texas, with a production capacity of 450 kton per year. We believe that this investment reinforces our PP leadership position in the region and strengthens our strategy to diversify the raw materials matrix and geographic expansion in the Americas. 64 Table of Contents Our renewables operations In September 2010, Braskem started up its green ethylene plant in Triunfo, in the state of Rio Grande do Sul, Brazil, with a capacity to produce 200 kton per year, becoming the world leader producer in biopolymers and products made from renewable sources, according to CMA. In February 2021, we announced a new project at the Triunfo petrochemical complex in Rio Grande do Sul to expand our current production capacity of green ethylene. The project added 60 kton per year to the production of green ethylene in our portfolio and was completed in April 2023. Additionally, in November 2021, Braskem and Lummus Technology LLC (“Lummus”), through our subsidiary Braskem Netherlands B.V., executed a memorandum of understanding to jointly develop and license our green ethylene technology. On April 28, 2022, we entered into a partnership agreement with Lummus, through our subsidiary Braskem Netherlands B.V., to develop and license our green ethylene production technology, reflecting our global interest in the technology. We are a pioneer in the production of resins made from renewable feedstock and have undertaken a commitment to reach production capacity of 1.0 million tons of bioproducts by 2030. Lummus has the technical capacity and experience in licensing to support us in developing and marketing our technology for producing green ethylene. The partnership brings the complementary expertise needed to accelerate the achievement of our commitment, expand the geographic footprint of green ethylene production technology globally and accelerate the use of bioethanol in chemical and plastic products, supporting the industry’s efforts towards a carbon neutral circular economy. In addition, the partnership is aligned with our sustainability objectives. In 2022, we officially announced the establishment of Sustainea, a joint venture between Sojitz and Braskem, which will be responsible for the production and marketing of bioMEG (monoethylene glycol) and bioMPG (monopropylene glycol), cutting-edge plant-based chemicals with lower CO2 production footprints. The joint venture offers two products: (i) bioMEG, a raw material used to produce PET, a product used to create bottles, textiles, and other types of packaging; and (ii) bioMPG, a raw material utilized in industrial, cosmetic, and personal care goods. In August, 2023, we entered into, through our subsidiaries Braskem Netherlands B.V. and Braskem Europe GmbH, a joint venture agreement with Thai Polyethylene Company Limited (“TPE”), a wholly owned subsidiary of SCG Chemicals Public Company Limited (“SCG Chemicals”), to establish Braskem Siam Company Limited (“Braskem Siam”), a joint venture company for conducting the project engineering for a green ethylene from ethanol dehydration plant using the EtE EverGreen™ technology ethanol-to-ethylene process technology. The investment is subject to, among other terms and conditions, approval by competent governance bodies. During 2024, Braskem Siam awarded Toyo Engineering Corporation with the Front End Engineering Design (“FEED”) contract of the project, which will be responsible for development of the extended basic engineering and the estimative for capital expenditures relating to the green ethylene plant in Thailand. The final investment decision (FID) is expected by the end of 2026, and represents an important step in the implementation project of the company's first industrial park in Asia. Our Global Strategy Our global strategic direction is structured around key pillars and foundations focused on strengthening financial capacity and improving our competitiveness position. The strategy seeks to balance profitability and financial health, optimize the current asset portfolio and execute transformative investments to ensure long-term business perpetuity. Resilience and financial health: the Company is implementing initiatives to mitigate the impacts of the industry’s prolonged downcycle through a resilience program (the “Resilience Program”), which has already delivered positive impact on our EBITDA and our cash generation. The Resilience Program encompasses strategic actions across investments and cost optimization, commercial strategy, operational efficiency, supplier negotiations and the engagement and support of the Company on the initiatives to defend and strengthen the Brazilian chemical industry. The program covers the following focus areas, among others: 65 Table of Contents a. Commercial initiatives to have incremental revenue from strategies such as increased volume and trading operations; b. Improvements to the terms of agreements with suppliers and portfolio agreements review, aiming to reduce costs and preserve the profitability of our business; c. Process optimization with efficiency growth, focusing on reducing fixed and variable costs, and increasing revenue; d. Discipline of capital allocation in investments, through the optimization of inventory, capital expenditures, and other cash outlays; e. The following competitiveness defense measures for the chemical industry, which have been essential to partially mitigate the commercial imbalance in the Brazilian domestic market: i. List of Conjunctural Trade Imbalances (LDCC): Inclusion of PE, PP and PVC resins on the List of Conjunctural Trade Imbalances (changing the rate from 12.6% to 20%); ii. PRESIQ (Special Sustainability Program for the Petrochemical Industry): approved the program that is expected to guarantee the industry a financial credit of R$15 billion between 2027 and 2031; iii. REIQ (Special Regime for the Chemical Industry): approved the Complementary Law providing for the increase, from 0.73% to 5.8% of the REIQ from March to December 31, 2026, with a budget limit of R$2 billion for the sector; iv. PE and PVC Antidumping: the Brazilian government approved the application of anti-dumping duties for resins imported from China (21%), Canada and the United States (8.2% to 43.7%), reinforcing the internal commercial defense. Business transformation: the Company is implementing actions to preserve and transform our current business. This includes executing asset strategy, increasing flexibility to gas-based assets and advancing bio-based projects implementation to support long-term competitiveness and value creation. Below we describe certain focus areas: a. The naphtha-based assets strategy considers the focus on cash generation: the Company completed the conversion of the chlor-alkali plant into a distribution unit, increasing flexibility in EDC and ensuring a more sustainable PVC production in Marechal Deodoro – Alagoas; b. The flexibility to gas-based assets aims at the improvement on cost competitiveness: Increase of the ethane-based capacity in Rio Janeiro by 220 thousand tons of ethylene per year under the Transforma Rio project, with a total estimated investment of approximately R$4.2 billion and implementation expected to be completed by the end of 2028; 66 Table of Contents c. The bio-based projects considers the leverage of competitiveness advantage in renewable products: Besides the expansion of our green ethylene capacity to 275 kton per year completed on the second quarter of 2025, Braskem is advancing on its joint-ventures with SCG Chemicals to build a new plant in Thailand, with a capacity to produce 200 kton per year of bio-based ethylene and polyethylene (PE); and joint-venture with Sojitz to build a new plant with capacity to produce 187 kton per year of monoethylene glycol (bioMEG) and monopropylene glycol (bioMPG). For the transformation projects, the following businesses and initiatives support and leverage their implementation: a. Innovation and Technology: the portfolio is designed to meet the current and future needs of our customers and to develop new businesses in bioproducts, creating value for our existing operations and building the Company’s future; b. Climate Change and Circular Economy: strengthening the Company’s integrated ecosystem of sustainable solutions, in alignment with the broader set of ongoing initiatives, promoting climate security and eliminating the plastic waste, together. For the next planning cycle, the Company expects to reinforce its previously defined strategic pillars, with a stronger emphasis on value creation as a core element of its strategic direction. This pillar is expected to focus on reinforcing the Company’s capital structure, ensuring the sustainability of our business.

The information included on our internet website, the internet website of our investor relations’ department, or the information that might be accessed through such websites, is not included in this annual report and is not incorporated into this annual report by reference. Our Competitive Strengths Leading Plastics Producer in the Americas We are the largest producer of plastics in the Americas, based on the annual production capacity of our plants, according to CMA. We are the only integrated petrochemical company producing basic chemicals and polymers in Brazil, and the largest producer of PE in Mexico and PP in the United States, according to CMA. Globally, we have total installed capacity of 20,325 kton per year. We produce a diversified portfolio of petrochemical and thermoplastic products, including polyethylene, PE I’m green™ bio-based, polypropylene, and PVC. Our products are typically used in large volume applications, and we benefit from our world-scale plants to enhance our competitiveness. According to CMA, global demand for PE, PP, and PVC in 2025 was estimated to be 121 million metric tons, 89 million metric tons, and 50 million metric tons, respectively. Between 2026 and 2029, global demand for PE, PP, and PVC is expected to grow on average by 2.3%, 2.7%, and 2.4% per year, respectively, according to CMA. This is driven by end market dynamics, global gross domestic product growth, and infrastructure and construction projects spending. Polymers will likely continue to replace traditional materials, such as aluminum, steel, wood, and glass, in applications where they can provide cost advantages and better performance. 68 Table of Contents Global Leader in PE I’m green™ bio-based, Pioneer in Renewable Plastics We are the global leader in PE I’m green™ bio-based production made from ethanol from sugarcane, 100% verified by ASTM D6866 standard of the American Society for Testing and Materials organization, and it is the first PE of renewable origin to be produced in industrial scale in the world, 100% drop in solution, which replaces the traditional alternatives without investment in new technologies. We have developed a global portfolio of clients, and our PE I’m green™ bio-based has around 217 customers in 41 countries for this product. PE I’m green™ bio-based also has a competitive price in comparison with most of the sustainable drop in solutions in the market. We benefit from our presence in Brazil, which is the world’s largest producer of ethanol from sugarcane, with ample access to bio-ethanol feedstock and a renewable energy matrix. Our PE I’m green™ bio-based stands out with distinctive advantages over other alternatives. Compared to biodegradable, recycled, and fossil-based PE, our renewable product offers: (i) a negative carbon footprint, supported by a proven Life Cycle Assessment (“LCA”) methodology based on C14 measurability; (ii) superior feedstock sustainability; (iii) lower operational risk and seamless compatibility with existing equipment due to identical processing requirements; (iv) established, proven technology and scalability; (v) identical properties and applications as fossil-based PE, providing a true drop-in solution; and (vi) enhanced recyclability, as it is 100% recyclable. Benchmark Operator, With World Class Safety Practices and Track Record We are widely recognized as an experienced and capable operator of petrochemicals plants. Our plants have recorded low accident rates and high utilization levels compared to industry peers. For example, our PP plants in the United States, from 2020-2024 achieved an average of 83% of utilization rate in comparison with the average of 81% in the region, according to CMA. Considering PE from Braskem Idesa in Mexico, the comparison is even wider, with an average of 74% from Braskem compared to the average of 51% for the country, considering the same period, according to CMA. Competitive Asset and Raw Material Base Our plants are located close to customer demand. In Brazil, in particular, competitors need to bring in products from locations as far away as the Middle East and face import tariffs which reduces their competitiveness compared to us. We rely on a diversified mix of raw materials, such as naphtha, ethane, propane, propylene and ethanol. We also source our raw materials from a diversified base of suppliers, which we continuously work to expand in the regions where we operate. In the United States Gulf Coast, we have a well-diversified supply base with well-developed pipeline connectivity that allow us to source feedstock at a competitive cost in the region. With 20 sources of supply in North America, our geographic and logistics diversity allows for redundancy in supply and flexibility at our PP plants. Global Marketing Platform We are a customer-focused organization and have built a deep network of local relationships with 2,839 customers worldwide as of December 31, 2025. We have a long history of development of long-term and close partnerships with clients, focusing on their needs and individual value creation solutions. Our market orientation and wide network are underpinned by a global platform with commercial offices in the Americas, Europe and Asia. Our global marketing platform combines market-focused teams for key market segments as well as regional teams for broader coverage. We encourage innovative thinking, an entrepreneurship mindset, a focus on the value chain and on product quality and service level. 69 Table of Contents Innovation and Technology, and Research and Development Capabilities Innovation and technology play a crucial role and initiatives in these fields are strongly linked to Braskem’s business strategies, supporting traditional business and future strategy, associated with decarbonization, bio-based and recycling. Focusing on enhancing technologies and developing new solutions is essential to remaining competitive in the market and achieving our strategic objectives. We drive innovation to extract value from our existing assets and create new value propositions to our customers. As a result of our innovation efforts, 6.7% of the product sales have been introduced in the last five years. We employ 352 employees globally in innovation and technology, spread across our research and development centers in Pittsburg and Lexington, Massachusetts (United States), Wesseling (Germany), Coatzacoalcos (Mexico), Triunfo, Campinas and São Paulo (Brazil). In 2025, even in a challenging scenario, we continued to invest in innovation to accelerate the creation of solutions that meet the demands of the market and society. We believe that innovation is an essential driver for building a more sustainable and resilient future. Qualified Management Team with Proven Success Our senior management team combines deep operational expertise and knowledge of petrochemical global markets developed over long tenures. We believe we have a strong mergers and acquisitions track record that supported our global expansion in the last decade, including into the United States and Europe, and we believe we have proven success in executing large and complex projects, including the (i) building of Braskem Idesa plants; (ii) construction of a new plant of PP in the United States (Delta Project); and (iii) development of the new ethane terminal in Mexico, the Terminal Química Puerto Mexico (“TQPM”), Industry Overview In both 2024 and 2025, the global economy maintained a growth trajectory similar to the previous year. This sustained growth was supported by the strong performance of the United States economy, a resilient labor market, and robust consumer spending, even after the aggressive policy rate hikes of 2022 and 2023. Additionally, faster-than-expected net export growth in China helped to mitigate some of the slowdown in consumption. On the other hand, the global economy was also influenced by high global interest rates aimed at controlling inflation, a slowdown in the Chinese economy, and ongoing tensions between China and the United States. The European manufacturing sector remained weak, and geopolitical conflicts persisted in regions such as Russia, Ukraine, and the Middle East. Regarding the petrochemical scenario, three structural changes or supply shocks have continued to impact global market dynamics: (i) the competitiveness of natural gas and ethane in the United States and the Middle East, which boosted ethane-based PE production and reduced naphtha's market share; (ii) China's pursuit of self-sufficiency, aiming to lead global supply chains and integrate refineries, creating an oversupply in the industry; and (iii) the reconfiguration of refineries, especially in Europe, reducing global naphtha supply, which has impacted and may continue to impact the cost of naphtha moving forward. These shocks, combined with a slower-growing global demand, have resulted in a surplus of products, especially in China, the United States, and the Middle East, which impacted and continues to significantly impact the margins of the petrochemical industry. 70 Table of Contents The price of crude oil also continued to oscillate drastically, in the tug-of-war between risk of supply disruption caused by geo-conflicts (prices up) and bearish demand (prices down). Meanwhile the so-called “golden age”, refineries that benefit from strong demand for gasoline and diesel, which is easing, are being impacted, as expected so that naphtha crack spreads, the difference between the price of naphtha and the price of crude oil, began to recover (and sustain) better levels of crack spreads, closing 2025 in the negative US$(5.4) per barrel levels, which is far from the negative double digits recorded in 2023 and 2022. The outcome of the weaker polymer prices and volatile (higher naphtha) feedstock was the decline in most petrochemicals’ spreads in the international market throughout 2025, with some upticks, which were not sustained. The uncertainties and challenging scenario are expected to continue in 2026, but some rationalization is expected for nonintegrated plants and older inefficient units that are vulnerable to intense competition, especially in the PP market, according to CMA, which may benefit spreads, along with the expectation of continuous improvement of economies (alongside of demand). In response to these conditions, during 2025 we implemented many initiatives to preserve our financial health and value creation such as, (i) optimization of asset operations, focused on cost discipline; (ii) implementation of financial initiatives, focusing on financial preservation of liquidity position and cash flow; (iii) prioritization of investments and reduction of requirements for capital expenditures, without impacting asset reliability; and (iv) advancement in all fronts related to the geological event in Alagoas, accomplishing the commitments in signed agreements. Industry Trends In April 2026, the IMF revised its projection for the world’s GDP growth in 2026 to 3.1%, an estimate that is 0.2 p.p. lower than forecasted in January 2026. According to the Fund, the apparent stability of global growth masks the balancing of divergent forces in the short term. On one hand, technology-driven investment, fiscal and monetary support, accommodative financial conditions, and strong private-sector adaptability continue to sustain activity, especially in North America and Asia. On the other hand, shifting trade policies and persistent policy uncertainty remain meaningful headwinds. The global disinflation is expected to continue, gradually converging toward targets in most major economies, but US inflation will return to target more gradually. Key downside risks are reevaluation of technology expectations and escalation of geopolitical tensions. According to IMF, several risks could impact global economic growth, predominantly downside risks, especially in the medium term. The IMF highlights the possibility of a reevaluation of productivity expectations linked to AI, geopolitical tensions, renewed trade frictions and the persistence of large fiscal deficits and public debt, all of which could disrupt supply chains, raise long-term interest rates, and increase uncertainty. On the upside, the IMF notes that activity could strengthen further if AI adoption effectively translates into productivity gains, enhancing business dynamism and generating more persistent growth. A sustained easing of trade tensions could also support activity. To safeguard the outlook and strengthen medium-term prospects, the IMF emphasizes the need for policies aimed at rebuilding fiscal buffers, preserving price and financial stability, reducing uncertainty, and advancing structural reforms without delay. Regarding the global petrochemical scenario, the expectation of external consulting firms for 2026 is a scenario of spreads that are similar to those of 2025, still challenged by additional capacities coming online in China. An upward trend of global consumption, based on macroeconomics of resolution of conflicts could partially revert this scenario, also an increase in the rationalization of inefficient capacities, might improve operating rates and consequently spreads. 71 Table of Contents Reportable Segments As of December 31, 2025, our business operations were organized into three segments, which corresponded to our principal production processes, products and services. Our reportable segments were as follows: Brazil Segment: includes: (i) the production and sale of chemicals, including olefins and specialties, at the Camaçari Petrochemical Complex in Bahia, the Triunfo Petrochemical Complex in Rio Grande do Sul, the Capuava Petrochemical Complex in the state of São Paulo, and the Duque de Caxias Petrochemical Complex in the state of Rio de Janeiro; (ii) the supply of electricity and other inputs produced in these complexes to second-generation producers located in the petrochemical complexes; (iii) the production and sale of PE, including the production of PE I’m green™ bio-based made from renewable resources, and of PP; and (iv) the production and sale of PVC and caustic soda (hibernated in September, 2025). United States and Europe Segment: operations related to PP production and sale in the United States and Europe, through the subsidiaries Braskem America and Braskem Netherlands B.V, respectively. Mexico Segment: comprises the activities related to the PE production and sale in Mexico, through the subsidiary Braskem Idesa. Brazil Segment We have 28 industrial units within four petrochemical complexes in our Brazil Segment (South America) that mainly use naphtha, ethane/propane, refinery off gas (ROG), and ethanol as feedstock to produce ethylene, propylene, green ethylene and their respective chemical co-products, which subsequently are used as feedstock to make thermoplastic resins (PE, PP, PVC and PE I’m green™ bio-based) or sold to third parties. As of December 31, 2025, our Brazil Segment had the largest annual PE, PP and PVC production capacity in South America, according to CMA. Our Brazil Segment generated net revenue of R$51,774 million during 2025, or 72% of the net revenue of our reportable segments. The following table sets forth our net revenue derived from sales of our Brazil Segment for the years indicated: For the Year Ended December 31, 2025 2024 2023 (in millions of reais) Net revenue: Brazil 51,774 54,844 49,512 Our Brazil Segment is comprised of the 1st and 2nd generation operations conducted by us. Our chemicals operations produce: · olefins, such as ethylene, polymer and chemical grade propylene, butadiene and butene-1, and others; · intermediates, such as benzene, cumene, paraxylene, ortho-xylene, and others; · fuels, such as gasoline, boosters, and others; · solvents, such as toluene, xylene, and others; and 72 Table of Contents · specialties, such as polyisobutene (PIB), hydrocarbon resin (Unilene®), isoprene, DCPD, piperylene, nonene and tetramer, I’m green™ bio-based PE wax, and others. Our polyolefins operations produce: · polyethylene, including LDPE, LLDPE, HDPE, EVA and PE I’m green™ bio-based made from renewable resources; and · polypropylene. Our vinyl’s operations include PVC production and, until September 2025, the manufacture caustic soda, which was mainly used by producers of alumina, pulp and paper, as well as in the soap industry. Our PVC production until September 2025 was integrated through the production of chlorine, ethylene and other raw materials. In September 2025, Braskem decided to hibernate its chlor-alkali unit to improve PVC competitiveness. It has not affected our PVC production capacity since we are importing the feedstock through a long-term agreement from a global supplier. Despite this change as of December 31, 2025, our PVC production plants had the largest annual production capacity in South America, according to CMA Products of our Brazil Segment The products of our chemicals operations are used primarily in the manufacture of intermediate second-generation petrochemical products, including those manufactured by our polyolefins and vinyls. Our chemicals operations also supply other second-generation producers in each of the petrochemical complexes in which we operate, and other companies located outside of these complexes, and renders services to those producers. The following table sets forth a breakdown of the sales volume of our olefins operations by product and by market for the years indicated (excluding our intra-company sales): Year Ended December 31, 2025 2024 2023 (in thousands of tons) Domestic sales: Ethylene 408 437 388 Propylene 236 270 265 Butadiene 156 166 156 Paraxylene 133 157 87 Benzene 471 475 400 Toluene 50 51 51 Gasoline 928 921 866 Cumene 178 211 193 Other chemicals 358 365 359 Total domestic sales 2,918 3,053 2,765 Total export sales 476 574 706 Total chemicals sales 3,394 3,627 3,471 Our polyolefins operations produce polyethylene, including LDPE, LLDPE, HDPE, UHMWPE, EVA, PE I’m green™ bio-based from renewable resources and polypropylene, including homopolymer and copolymer grade.

Vinyls Operations We operated four vinyl production plants: one located in the Northeastern Complex and three located in the state of Alagoas, in Brazil. In September 2025, the Company decided to hibernate its last chlor-alkali unit, located in Maceió, state of Alagoas. The decision was part of the long-term strategy to improve competitiveness and better serve customers. In January 2020, Braskem announced the permanent shutdown of its chlor-alkali production facility located in Camaçari, in the State of Bahia, in Brazil whose operations started in 1979 with annual production capacity of 79,000 tons of caustic soda and 64,000 tons of chlorine. The shutdown is explained by the end of the facility’s useful life and started in April 2020, following applicable safety standards and seeking to protect people, local communities and the environment. The table below sets forth for each of our primary vinyls products, our annual production capacity as of December 31, 2025, and annual production for the years presented: 75 Table of Contents Annual Production Production For the Year Ended December 31, Primary Products Capacity 2025 2024 2023 (in thousands of tons) PVC 730 439 462 493 Caustic Soda 460 until Sep/25(1) 128 266 303 ____________ (1) In September 2025, Braskem decided to hibernate its chlor-alkali unit to improve PVC competitiveness. Raw Materials of Our Brazil Segment Naphtha The main raw material that we use for chemical production is naphtha, with a total consumption capacity of up to 10 million tons per year. Up to one-and-a-half million tons of naphtha can be substituted by condensate, which in recent years was about one million tons. Natural gasoline is also a feedstock that can be used as a replacement for naphtha. The cracker located in Rio de Janeiro uses ethane and propane, and its consumption is 0.4 million tons of each of these raw materials per year. The São Paulo cracker can also consume refinery off gas in a quantity equivalent to about 15% of the ethylene production capacity. As a reference, the following table shows the average Amsterdam-Rotterdam-Antwerp, or the ARA price, of naphtha for the periods indicated. 2025 2024 2023 (in US$/t) Average(1) 567 765 643 (1) The information in the “Average” row represents the mean average monthly naphtha prices during each respective year. Source: Braskem Global Market Intelligence. As part of our strategy to diversify our sources of supply of naphtha, we acquire naphtha and condensate under annual supply arrangements with international suppliers. We also purchase naphtha on the spot market from time to time from foreign suppliers located in Africa, Europe, North America and Latin America. In addition to our supplies of naphtha, we purchase condensate on the spot market from time to time from foreign suppliers. The following table shows the distribution of naphtha plus condensate purchases by our Brazil Segment for the periods indicated by geographic location of the suppliers.

In 2025, the ethylene consumption of our polyethylene operations was totally supplied by our chemicals plants and the propylene consumption of our polypropylene plants were supplied by our chemicals operations and by external sources. The most significant feedstock associated with the production of PVC is ethylene. Our chemicals operations that are part of our Brazil Segment supply all the ethylene required by our vinyls operations. Other Materials and Utilities Our polyolefins operations that are part of our Brazil segment use butene, hexene, vinyl acetate and propane as raw materials in the production of HDPE, LDPE, EVA, UTEC, MTLPE and LLDPE. Butene is consumed from our chemicals operations. We import hexene and vinyl acetate from many suppliers around the globe, and propane we buy from Brazilian suppliers. In our polypropylene operation we use butene as raw material in the production of terpolymer. Butene is supplied from our chemicals operations. Our polyethylene plants also use catalysts supplied by many suppliers around the globe. We also produce our own catalysts for our HDPE slurry plants in the Southern and Northeastern Complexes, and we purchase the inputs that we need to produce these catalysts from many suppliers at market prices. Our polypropylene plants also use catalysts supplied from a national and international supplier. Additives are consumed in the extruder process to reach certain properties of the final product. Some examples are antioxidants, clarifiers, flow aids and neutralizers. Salt We consumed 229 kton of salt during 2025, which were all imported from Chile, dissolved in water to make brine, and then treated and sent for processing. In 2025, we produced 128 kton and imported 35 kton of caustic soda to supply our customers. Also, we produced 149 kton and imported 238 kton of ethylene dichloride, which is consumed in PVC production, to supply our PVC plants located in the state of Alagoas and in the Northeastern Complex. Salt mining operations at our mine were shut down in May 2019, as described in “Item 3. D Risk Factors—Risks Relating to Us and the Petrochemical Industry—Our business and operations are inherently subject to environmental, health and safety hazards. As a result, our business is also subject to strict environmental and other regulations” and “Item 8. Financial Information—Legal Proceedings—Alagoas – Mining Activities.” Supply Contracts of Our Brazil Segment Naphtha Throughout 2025, Braskem and Petrobras had naphtha supply contracts in effect to provide naphtha for our plants in the Southern Complex, the Northeastern Complex, and the São Paulo Complex. These agreements expired in December, 2025 and were renewed, while the new contracts have a new term of five years, until the end of 2030. Under the terms of these new agreements: 77 Table of Contents · Petrobras has agreed to sell and deliver naphtha, for a period of five years, to our chemical plants in the Northeastern, Southeastern and the Southern Complex exclusively for our use as a feedstock; · we are required to purchase a minimum monthly volume of naphtha for each of our Complexes; · we have the option to purchase additional volume for the São Paulo Complex and Petrobras has an option to sell us additional volume for our Northeastern and Southern Complexes; · we may request volumes of naphtha that exceed a monthly firm commitment order, which Petrobras may supply at its discretion; · the price we pay for naphtha is based on international price references; · the contract could be terminated or amended in the event that unforeseen extraordinary events occur that cause a disruption in the economic-financial equilibrium of the contract; · either party may terminate the contract in the event of, among others: (1) failure to cure any breach of the contract following a 30-day grace period; (2) a force majeure event that continues for more than 90 days; (3) assignment or transfer, in whole or in part, of the rights and obligations under the contract to a third party without the other party’s consent; (4) assignment or offering as guarantee, in whole or in part, of credits of any nature arising from or originating from the contract without the other party’s consent; (5) an alteration of ownership or corporate purposes that conflicts with the purpose of the contract; (6) dissolution; (7) failure to comply with the compliance obligations of the contract; (8) bankruptcy; or (9) unappealable court decision approving an out-of-court reorganization plan or granting judicial reorganization, if the other party fails to provide adequate security or sufficient collateral to ensure the due performance of its contractual obligations. In December 2021, ACELEN concluded the acquisition of REFMAT, a refinery previously owned by Petrobras, located in the state of Bahia, and one of the suppliers for our Northeastern Complex. As per the terms and conditions of the sale and purchase agreement, the supply agreement originally entered into by Petrobras was assigned to ACELEN. This Agreement expired in December 2025. In 2026, the purchases are being made on a spot basis. Ethane and Propane Ethane and propane are the main feedstocks that we use to produce our chemical products in the Rio de Janeiro Complex and represent the principal production and operating cost of the petrochemical cracker in the Rio de Janeiro Complex. The price of ethane and propane that we purchase varies primarily based on changes in the U.S. dollar-based international price of these feedstocks. The existing contract expired on December 31, 2025. In December 2025, we and Petrobras entered into a new ethane and propane supply agreement with a term of up to eleven years, from January 1, 2026 to December 31, 2036 as follows: · we are required to purchase, and Petrobras is required to deliver a minimum annual volume of ethane and/or propane; · the volume of ethane is expected to increase in 2029, which will increase the ethylene production from 580 kton to 725 kton per year; · the prices for ethane and propane are based on international price references; · the contract could be terminated or amended in the event that unforeseen extraordinary events occur that cause a disruption in the economic-financial equilibrium of the contract; and 78 Table of Contents · either party may terminate the contract in the event of, for example: (1) failure to cure any breach of the contract following a 60-day grace period; (2) a force majeure event that continues for more than 180 days; (3) assignment or transfer, in whole or in part, of the rights and obligations under the contract to a third party without the other party’s consent; (4) assignment or offering as guarantee, in whole or in part, of credits of any nature arising from or originating from the contract without the other party’s consent; (5) dissolution, bankruptcy or unappealable court decision approving an out-of-court reorganization plan or granting judicial reorganization which materially impacts the other Party’s ability to perform its obligations; (6) upon prior written notice given at least 120 days in advance, with respect to a change in the shareholding structure involving the shareholders holding a majority of the voting capital, if the new shareholder holding a majority of the voting capital fails to meet the other Party’s compliance requirements in the due diligence. Braskem also has an ethane supply contract with Enterprise Products Operating LLC (“Enterprise Products”), to supply ethane from the United States to Brazil. This agreement will remain valid until 2027. The price of ethane is based on the Mont Belvieu ethane price plus a Terminal Fee, basis FOB USGC. The logistics to move the ethane to Brazil is managed by Braskem. Since February 2017, Braskem has had the capability to receive imported ethane at the Rio de Janeiro Complex. Since November 2017, Braskem has the capacity to consume ethane in the cracker in Bahia, partially replacing naphtha. Braskem has invested to create the flexibility to substitute naphtha for ethane in a ratio equivalent to 15% of the ethylene production of the site. 2018 was the first year in which we operated our cracker in Bahia using imported ethane as feedstock. Of the total ethylene produced by the cracker, there was no consumption of imported ethane as feedstock in 2025, 4.6% of ethane feedstock in 2024 and 0.7% of ethane feedstock in 2023. The imported ethane in our Brazilian operations is marginal to domestic supply and the quantity imported in 2025 was 65 kton, in 2024 was 73.5 kton and in 2023 it was 17.7 kton. Refinery Off Gas In January 2005, we entered into an agreement with Petrobras for the purchase and sale of steam from refinery off gas, from which we separate ethylene and propylene. This agreement was valid for a term of 15 years and contained a provision requiring the parties to negotiate its extension prior to its expiration in 2020. This agreement also contained a provision pursuant to which Petrobras was required to notify us at least two years prior to its expiration of its intention to renew the agreement, and if Petrobras notified us of its intention not to renew it, then the agreement would remain valid under its original terms and conditions for eight additional years until 2028. In December 2017, Petrobras informed us that they would not renew this agreement on the same terms and conditions. Therefore, the contract will remain valid under its original terms and conditions until 2028. The impact of the new terms and conditions of a possible future agreement after 2028 and any failure to successfully negotiate such terms with Petrobras could impair our ability to satisfy our refinery off gas needs. Under the terms of this agreement, which represents 100% of our refinery off gas supply: · we are required to purchase a minimum daily volume of refinery off gas, and Petrobras is required to sell a minimum daily volume to us; · the price for refinery off gas is based on a variety of market references; 79 Table of Contents · the contract will be amended in the event that unforeseen extraordinary events occur that cause a disruption in the economic-financial equilibrium of the contract; and · Petrobras may terminate the contract, without prior notice, in the event of: (1) our failure to cure any breach of the contract following a 30-day grace period; (2) a force majeure event that prevents the execution of the contract; (3) a transfer or pledge by us, as a guarantee for indebtedness, of all or part of our rights, obligations and credits under this contract to a third party without Petrobras’ consent, unless the third party is a member of our economic group; (4) the dissolution or bankruptcy of Braskem S.A.; or (5) a change in business structure, merger, sale, spin-off or any other corporate reorganization of Braskem S.A. that conflicts with or impedes the execution of contract’s purpose. In 2024, Braskem and Petrobras terminated the existing contract and signed a new one. There were no changes in commercial conditions (such as volume, price and term) between the former contract and the new one. Propylene Contracts We have entered into multiple propylene agreements, which had initial terms expiring at various dates between May 2021 and December 2029, some of which were automatically renewed for five additional years and are priced based on international references to assure competitiveness of feedstock. In 2016, Braskem entered into an agreement with Petrobras for a five-year propylene supply contract with REFAP S.A. (“REFAP”), a subsidiary of Petrobras. This supply contract is priced based on international references. In October 2021, Petrobras and Braskem renewed for one year the propylene supply contract with REFAP. The contract lasted between November 2021 and October 2022 and had the same volume and pricing conditions as the previous contract. In December 2021, Petrobras and Braskem entered into five new propylene contracts, to be supplied by REPLAN, REVAP, REPAR, REDUC and RECAP, which replaced the existing contracts. These contracts expire between 2026 and 2029 and are priced on international references to assure the competitiveness of feedstock. In December 2025, Petrobras and Braskem entered into three new propylene contracts, to be supplied by REDUC, RECAP and REFAP. These new contracts will last for five years, from May 2026 to April 2031. The new agreements with RECAP and REDUC will replace the existing ones, that expire in May 2026. Either party may terminate these contracts in the event of, for example: (1) failure to cure any breach of the contract following a grace period; (2) a force majeure event occurs, although some of these contracts require that the force majeure event continues for more than 180 days; (3) assignment or transfer, in whole or in part, of the rights and obligations under the contract to a third party without the other party’s consent; (4) certain shareholding changes; (5) the dissolution, bankruptcy or out-of-court reorganization plan or judicial reorganization. During 2025, Braskem and Petrobras signed four short-term propylene contracts, to be supplied by REFAP. All these contracts were signed and terminated in 2025. Ethanol Supply Contracts We buy ethanol from Brazilian producers to supply our facility that produces ethylene and ETBE, using sugar cane ethanol. We have ethanol supply agreements that will terminate in 2026 and 2027. We also purchase ethanol on the spot market from time to time to supplement the contracted volumes. Under the contracts we have, we are or will be required to purchase an annual supply of ethanol sufficient to meet at least 83% of the capacity of this ethylene plant. The price we pay under these contracts is or will be determined by reference to the price of combustible hydrated alcohol as published by the Center for Advanced Studies in Applied Economics of the Superior School of Agriculture (Centro de Estudos Avançados em Economia Aplicada da Escola Superior de Agricultura– CEPEA/ESALQ). 80 Table of Contents Electricity Our industrial operations in Brazil represented 80% of our global electric consumption in 2025 and we self-generated 27% of our electrical energy consumption by on-site thermal cogenerations. We currently have a mix of long-term and medium-term energy contracts. 44% of these contracts in 2025 were in an off-site self-production model, in which we purchase a stake in certain wind and solar assets for our own generation of renewable electricity. Out of the total amount of energy we consumed in 2025, 84% was from renewable sources, considering the purchase of renewable energy, including renewables certificates, renewables asset contracts and renewable percentage of the grid. This percentage was 1% higher than in 2024. Natural Gas Until 2024, Braskem was supplied, in Brazil, exclusively through contracts in the regulated market. During 2025, five industrial units switched to the free natural gas market, enabling access to more competitive pricing and increasing the flexibility of our operations. By the end of 2025, 64% of our consumption was still in the regulated market and 36% was in the free market. The natural gas consumed by our operations in Brazil in 2025 represented 62% of our consolidated consumption. Steam and Coal Steam is essential to our industrial processes. Most of the industrial units generate their own steam from the burning of fuels. In some units, we purchase steam from third parties under long-term contracts. In 2025, 85% of the total amount of our purchased steam was for our operations in Brazil. In Brazil, coal is used to generate steam in our unit located in the petrochemical complex at Rio Grande do Sul. During 2025, coal represented 11% of the energy purchased globally by us. Sales and Marketing of Our Brazil Segment The Brazil Segment is an integrated business with the production and sale of first and second generation chemicals, including olefins, specialties, vinyls, and polyolefins. The focus of our Brazilian operations is to maintain our leading position in Brazil and South America through a continued local presence and regular product supply, reinforcing our commitment to the chemical and plastic industry chain in the region, continuing to use our exports to optimize our operations and adjust the imbalances between demand and production. Since we export large volumes of certain products, we also develop long-term relationships with international customers through contracts that minimize our exposure to market conditions and mitigate risk. We sell most of our olefins products in Brazil to third-party petrochemical producers. We sell the remainder of our products to customers in the United States, Europe, South America and Asia. 81 Table of Contents Our specialty products are mainly utilized in the production of intermediate second generation petrochemical products. We also supply other second generation producers within the petrochemical complexes where we operate, as well as companies outside these complexes, and provide services to these producers. The primary applications of our products include adhesives, rubbers, cosmetics, lubricants, paints, fuels, and boosters. Through our polyolefins operations, we sell polyethylene and polypropylene products to 1,114 customers worldwide. We have a diversified product mix that allows us to serve a broad range of end users in several industries. The customers of our polyolefins operations generally are third generation petrochemical producers that manufacture a wide variety of plastic-based consumer and industrial goods. There is a structural link between the PVC and caustic soda markets because caustic soda is a co-product of the production of chlorine required to produce PVC. Most of the time, when demand for PVC is strong, greater amounts of caustic soda are produced, leading to an increase in supply and a decrease in prices for caustic soda. Conversely, when demand for PVC is weak, prices for caustic soda tend to rise. Sales of Chemicals operations As part of our commercial strategy, we are focused on developing short and long-term relationships with our customers. Our olefins operations focuses entering into long-term supply contracts that provide for minimum and maximum quantities to be purchased on a monthly basis. The domestic market pricing is based on international market references. We establish our domestic price for specialties based on international spot market prices, plus exchange rate variation. The domestic price for specialties is based on the international reference, which generally reflects the spot market price, plus service margin and exchange rate variation. Delivery time, quality and technical service also affect the levels of sales of specialties products. Sales of Polyolefins operations As part of our commercial strategy, we are focused on developing short- and long-term relationships with our customers. Given the cyclical nature of the markets for our polyolefins operations, we believe that we can strengthen customer loyalty during periods of reduced demand for polyethylene or polypropylene by providing a reliable source of supply to these customers during periods of high demand. We work closely with our customers to provide technical assistance and to coordinate the production and delivery of our products. Despite having a regular client basis in the domestic market, prices in such market are driven by monthly spot negotiations. Both sales volume per client and the types of products our clients purchase may vary on a monthly basis. In addition to direct sales of polyolefins to our customers, through our polyolefins operations, we sell products in Brazil through exclusive independent distributors. Our polyolefins operations are served by five distributors, through which we distribute our products pursuant to formal agreements and spot market transactions. We have selected our distributors based on their ability to provide full service to their customers, and also based on their background. These distributors sell our polyethylene and polypropylene products to manufacturers with lower volume requirements and are able to aggregate multiple orders for delivery. They have a wide coverage network in Brazil and, as a result, expand the Braskem brand. Furthermore, by providing customized services and serving smaller customers through a network of distributors, our account managers focus their efforts on delivering high quality service to a smaller number of large and medium direct customers. Our volume of polyolefins export sales has generally varied based upon the level of domestic demand and the total production availability for our products. Our polyolefins operations have commercial offices in Argentina, Chile, Peru and Colombia. These offices are used to consolidate our marketing efforts in South America, one of our key markets outside of Brazil. Our polyolefins operations may also use the European, Mexican and United States sales force of our United States and Europe Segment and Mexico segment in order to improve the competitiveness of our export sales from Brazil Segment. In each of these regions, we have specific commercial strategies in connection with exports coming from Brazil, which complements our local product availability. 82 Table of Contents We have established a strategic position in the polyolefins business in South America, North America, Europe and Asia through regular direct sales, local distributors and agents who understand their respective markets. The strategy to increase our presence in these foreign markets is intended, among other things, to reduce our exposure to the cyclicality of the international spot market for polyolefins through the development of long-term relationships with customers in neighboring countries. Our local presence allows us to further enhance our position in those markets and sell our polyolefins operations that are part of our Brazil Segment’s products through our United States and Europe Segment. Sales of Vinyls operations Most of our sales of PVC and caustic soda are sold to Brazilian customers and we use third-party distributors to serve smaller and/or specific caustic soda customers. To provide a better logistics support to our Brazilian PVC customers, we serve them through five distribution centers, on a contractual basis, located in: Piracicaba, Mauá and Sumaré, in the State of São Paulo; Joinville, in the State of Santa Catarina; and Araucaria, in the State of Paraná. In addition, we operate 12 warehouse facilities for PVC, on a non-exclusive basis, and five terminal tank facilities (Aratu-BA; Vila Velha- ES; Rio de Janeiro- RJ; Santos – SP; Paranaguá – PR) for caustic soda strategically located along the Brazilian coast to enable us to deliver our products to our customers on a “just-in-time” basis. Our vinyls operations work in close collaboration with its customers, working together to improve existing products as well as to develop new applications for PVC. Our marketing and technical assistance groups also advise current customers and potential ones that are considering the installation of new manufacturing equipment for PVC downstream products. In addition, in 2025 we decided to cease supplying the Brazilian market with emulsion PVC and other copolymers with higher value through imports from our vinyls operations. Prices and Sales Terms We determine the prices of our products in accordance with international pricing references. In addition, we consider segment, volume, and other information when we set our prices. Our customers in Brazil may pay in full on delivery or elect credit terms that require payment in full within three to 60 days following delivery. We charge interest based on prevailing market rates to our Brazilian customers that elect to pay on credit. In addition, besides our strategic sales to South America, Europe, Mexico and the United States, our polyolefins operations that are part of our Brazil Segment generally conducts export sales to buyers in Asia and Africa through the international spot market. Our customer base in these markets consists primarily of trading houses and distributors. The domestic price for PVC resins is based on the import parity of PVC imported by converters in Brazil, which generally reflects the Northeast Asian spot market price, plus exchange rate variation. Delivery time, quality and technical service also affect the levels of sales of PVC resins. We establish our domestic price for caustic soda based on North American spot market prices, plus exchange rate variation. 83 Table of Contents Competition Chemicals Operations During the past several years, as the relative cost of naphtha and gas as feedstock for petrochemical crackers has diverged, many crackers using gas as a feedstock have become low-cost producers in the global markets and have seen their margins improve as compared to naphtha crackers. Competition in the international markets for these products is primarily based on the price of delivered products and competition has increased since mid-2008 as the balance between supply and demand was disrupted due to the impact of the global economic downturn on consumers of these products. In the international markets for our olefins products, we compete with many producers, some of which are substantially larger and have substantially greater financial, manufacturing, technological and marketing resources than us. Our main competitors in the specialties market are national and international petrochemical companies operating in Brazil, national and international refinery companies and producers located in the U.S. Gulf Coast. Polyolefins Operations We are the only producer of polyethylene and polypropylene in Brazil. We compete with polyolefins producers worldwide. In 2025, Brazilian polyethylene and polypropylene imports decreased by 1% and represented 49.5% of Brazilian polyolefin consumption. We compete for export sales of our polyolefins products in other countries in Latin America and in the North American, Asian and European markets. Similar to Braskem, those competitors also have a wide portfolio, ample research and development capabilities and sufficient production capacity. Our competitive position in the export markets that we serve is based on customer relationship, extensive product portfolio, product quality and customer service and support. Vinyls operations Unipar Indupa (formerly Carbocloro and Solvay), or Unipar, and Braskem are the only two PVC producers in Brazil. According to CMA, Unipar’s total Brazilian installed annual production capacity is 299 kton, compared to our annual production capacity of 730 kton. Unipar’s Brazilian production plants are located in São Paulo, closer to the primary PVC market in Brazil, whereas our plants are located in the Northeast of Brazil. However, we believe that our strong relationship with our customers and our technical assistance programs enable us to effectively compete with Unipar and to make up for any competitive disadvantage due to geographical distance from the market. In addition to its Brazilian plants, Unipar also has a PVC plant in Argentina that, together with other PVC importers, compete with Braskem. According to ComexStat, imports from all regions accounted for 47.6% of Brazilian PVC consumption in 2025. Most of the imported volume comes from Colombia (Mexichem) that, due to a bilateral agreement with Brazil, can import products without import taxes. Domestically produced PVC is currently competitively priced with imported PVC, considering that our price is based on the international market. Braskem competes with other producers of thermoplastics resins, mainly polyethylene and polypropylene, that can replace PVC in certain applications. Wood, glass, and metals also are used in some cases as substitutes for PVC. According to CMA and Abiclor (Associação Brasileira da Indústria de Álcalis, Cloro e Derivados), the three largest Brazilian producers of caustic soda, including Braskem, accounted for 68.6% of capacity in Brazil in 2025. 84 Table of Contents In 2025, Brazil’s total caustic soda consumption was 1,552 kton, 45% of this consumption is attributed to imported caustic soda, based on Abiclor, which includes Braskem own imports to supply part of the market (34.6 kton).Our main competitors in the caustic soda market are other international petrochemical companies operating in Brazil and producers located in the U.S. Gulf Coast. United States and Europe Segment Our United States and Europe Segment includes: · the operations of Braskem America, which consist of five polypropylene plants in the United States and one Ultra High Molecular Weight Polyethylene – the UTEC® plant; and · the operations of two polypropylene plants in Germany. As of December 31, 2025, our United States and Europe Segment’s plants had the largest annual polypropylene production capacity in the United States, according to CMA. Our United States and Europe Segment generated net revenue of R$16,400 million during 2025, or 23% of the net revenue of all reportable segments. In September 2023, a decision was made to hibernate one of the two polypropylene lines at the Marcus Hook plant in Pennsylvania. The hibernation of this line was implemented to ensure the long-term resilience of Braskem’s United States polypropylene business amid continuing global economic uncertainty and a trough in the chemical industry business cycle. Products of Our United States and Europe Segment Our United States and Europe Segment produces polypropylene. The sales volume of polypropylene by this Segment was 1,978 kton in 2025, 1,957 kton in 2024 and 2,110 kton in 2023. For a description of the uses of our polypropylene products, see “Products of Our Brazil Segment.” Production Plants of our United States and Europe Segment The table below sets forth the annual production capacity as of December 31, 2025, of the United States and Europe Segment’s polypropylene plants in the United States and Germany and the annual production for the years presented: Annual Production Capacity Production For the Year Ended December 31, Plant 2025 2024 2023 (in thousands of tons) United States 2,021 1,545 1,521 1,643 Germany 625 410 432 494 Raw Materials of Our United States and Europe Segment Propylene The most significant direct cost associated with the production of polypropylene by our United States and Europe Segment is the cost of purchasing propylene. We supply our plants in the United States and Europe Segment mainly through contracts from different sources, such as refineries, steam crackers and propane dehydrogenation plants (“PDHs”). The PDHs are on-purpose propylene plants that were a result of rising natural gas production and related production of natural gas liquids. Several companies have announced plans to build these plants utilizing these abundant liquids as an input. In the United States, we have secured a long-term propylene agreement with Enterprise Products, which operates a PDH plant in Texas with an annual capacity of 750 kton. We expect this agreement to provide us with a competitive, long-term supply of propylene, using shale gas and other nontraditional sources as its feedstock. Under this arrangement, the pricing of these contracts will be based on market prices for propane and other market costs 85 Table of Contents Supply Contracts of Our United States and Europe Segment We acquire propylene for our polypropylene plants in the United States under a variety of long-term supply agreements and through the spot market. As of December 31, 2025, we had 18 propylene supply agreements and two ethylene supply agreements. The pricing formulas for propylene under these supply agreements are generally based on international market prices. We acquire propylene for our polypropylene plants in Germany under long-term supply agreements that provide approximately 92% of the propylene requirements of these plants. We have two main supply agreements in Germany. The price quotation for propylene under these longer supply agreements are related to the monthly contract price for propylene for Europe (as reported by ICIS-LOR), varying their discounts and/or formula rationale according to each supplier. Sales and Marketing of Our United States and Europe Segment Our United States and Europe Segment sells polypropylene products to 370 customers. We have a diversified product mix that allows us to serve a broad range of end users in several industries. The customers of our United States and Europe Segment generally are third generation petrochemical producers that manufacture a wide variety of plastic-based consumer and industrial goods. The following table sets forth our net revenue derived from sales of our United States and Europe Segment for the years indicated: For the Year Ended December 31, 2025 2024 2023 (in millions of reais) Net revenue: United States and Europe 16,400 19,444 17,507 In the United States and Europe Segment, contracts or general supply agreements with our clients account for 78% of polypropylene sales. These contracts typically last one year and have the option of being renewed at the end of the term. Additionally, these agreements specify required minimum and maximum purchase quantities as well as monthly deliveries. The remainder of the polypropylene production of the United States and Europe Segment is sold through (1) our direct sales force that seeks to establish supply relationships with customers; (2) a select number of distributors authorized to represent the Braskem brand in the U.S. and European markets; (3) resellers that trade these products under private labels in the North American and European markets; and (4) traders that resell these products in the export markets. Prices and Sales Terms The domestic price for PP resins in the United States and Europe Segment reflects the market price, considering the differences between contract and spot prices, or propylene plus pricing. Delivery time, quality and technical service also affect the levels of sales of resins and usually export prices for PP are based on spot market references. 86 Table of Contents Competition The United States and Europe Segment is largely a commodities business and competes with local, regional, national, and international companies, some of which have greater financial, research and development, production and other resources than us. Although competitive factors may vary among product lines, our competitive position is primarily based on raw material and production costs, selling prices, product quality, product technology, manufacturing technology, access to new markets, proximity to the market and customer service and support. Our primary competitors for sales in the polypropylene industry in North America and Europe are other large international petrochemical companies. In general, demand is a function of economic growth in North America, Europe and elsewhere in the world. Mexico Segment Braskem and Idesa, one of Mexico’s leading petrochemical groups, formed Braskem Idesa S.A.P.I. in April 2010, with Braskem holding 75% of the total share capital and Idesa holding the remaining 25%, to develop, construct and operate the Mexico Complex, located in the Mexican state of Veracruz. During April 2016, Braskem Idesa commenced commercial operations of the Mexico Complex. As of December 31, 2025, our Mexico Segment had the largest annual polyethylene production capacity in Mexico, according to CMA. Our Mexico Segment generated net revenue of R$4,103 million during 2025, or 6% of the net revenue of all of our reportable segments. Products of Our Mexico Segment Our Mexico business unit produces ethylene, HDPE and LDPE at our Mexico Complex. We use all of the ethylene produced by our Mexico Complex as raw material for the production of polyethylene by this complex. The sales volume of polyethylene by this unit was 708 kton in 2025. Our Mexico Complex manufactures a broad range of polyethylene grades for use in consumer and industrial applications, including plastic films for food and industrial packaging, bottles, shopping bags and other consumer goods containers, automotive parts, and household appliances. Braskem Idesa remains focused on the growth of the PCR market, especially on product development and marketing capacity through partnerships and strategic alliances. Technologies selected for the Mexico Segment are proven in the petrochemical market and we believe it provides a competitive advantage in serving our customers to meet their specific needs by adapting and modifying our polyethylene products. Production Plants of Our Mexico Segment Our Mexico Segment operates four plants located in the Mexico Complex, consisting of: · an ethylene cracker, with an annual production capacity of 1,050 kton of ethylene, which commenced operations in March 2016; · two high-density polyethylene plants, with a combined annual production capacity of 750 kton, which commenced operations in April 2016; · a low-density polyethylene plant, with an annual production capacity of 300 kton, which commenced operations in June 2016; 87 Table of Contents · a 175.6 megawatt power generation plant consisting of one gas turbine (85.6 megawatts), two electric generators with steam turbines (45 megawatts each) and two auxiliar boilers (200 t/h); · an effluents treatment plant and a water treatment plant, which return water to the community in a condition that exceeds the applicable regulatory requirements; and · A logistic platform and distribution network consisting in 20,000 m2 of warehouse, more than 30,000 m2 of open space capacity, 21 silos (1,050 m3 each one), 14 loading docks and 14 km of rail tracks. Annual Production Production For the Year Ended December 31, Plant Capacity 2025 2024 2023 (in thousands of tons) Mexico (Polyethylene) 1,050 668 820 808 Raw Materials of Our Mexico Segment The principal raw material used in our Mexico Complex is ethane, in addition to other raw materials such as hexene, propylene and polyaldehyde (PAL). Other chemicals, catalyzers, additives and utilities such as natural gas, electricity and nitrogen are used to produce polyethylene in the Mexico Complex. Ethane Ethane is the principal raw material that we use to produce ethylene in the Mexico Complex and represents the principal production and operating cost of the Mexico Complex. The price of ethane that we purchase varies based on changes in the U.S. dollar-based U.S. reference price of these feedstocks. We currently source ethane, from two main sources: (i) locally, pursuant to the Ethane Supply Agreement with Pemex, a state-owned Mexican entity; and (ii) since October 2025, our Ethane Import Terminal, a long-term alternative source of imported ethane, and a 10 kilometer pipeline that connect the terminal directly to our Complex, through its subsidiary Terminal Química Puerto Mexico, S.A.P.I. (“TQPM”). As of the years ended December 31, 2025, 2024 and 2023, ethane supply from Pemex was 42%, 58% and 65% respectively and 58%, 42% and 35% respectively, from imported ethane. Braskem Idesa built an Ethane Import Terminal, a long-term alternative source of imported ethane, and a pipeline that connect the terminal directly to our Complex, through its subsidiary Terminal Química Puerto Mexico, S.A.P.I. (“TQPM”), which started operations in October 2025. The ethane capacity of the Ethane Import Terminal is enough to fulfill the total ethane needs for the Mexico Complex. This terminal provides the capacity to import more ethane than we currently require. As a result, our Mexico Segment will be able to source its total needs towards increasing our polyethylene production and taking advantage of the forecasted demand for polyethylene products in North America and globally. The estimated cost of the Ethane Import Terminal and related infrastructure investment is R$3,191million (US$580 million) excluding VAT, after the conclusion of several activities related to licenses, purchase of land and easement contracts, and a review of project and implementation costs for the new company. 88 Table of Contents On June 13, 2022, Braskem Idesa and TQPM entered into a stock purchase agreement with Advario, a carve-out of Oiltanking GmbH for a 50% equity stake in TQPM. The Mexican Antitrust agency (COFECE) approved such purchase on October 3, 2022. On March 1, 2023, Braskem Idesa received the payment of R$316 million (US$56 million) (including VAT) referring to the capital contribution disbursed, which was equivalent to 50% interest in TQPM’s capital by Braskem Idesa until the respective date, totaling R$584 million (US$112 million) (including VAT). The Ethane Import Terminal started operations in October 2025. On October 2023, with the support of its shareholders, Braskem Idesa and Advario, TQPM secured the financing of R$1,975 million (US$408 million) Senior Loan by INBURSA, ING KFW-IPEX, Credit Agricole, Mizuho, and DEG. It is a syndicated project finance loan, a five-year mini-perm deal with standard guarantees for a transaction of this type. The capital structure of the project was 30% equity and 70% debt of the total investment. For additional information, see “Item 3. D Risk Factors— Risks Relating to Us and the Petrochemical Industry — We depend on ethane supplied by Pemex in Mexico,” and “—We rely on limited or sole-source suppliers for our raw materials, inputs and energy, including transportation thereof.” Ethylene All the ethylene produced by our Mexico Complex is used by the polyethylene plants in our Mexico Complex. Other Materials and Utilities Our Mexico Segment uses natural gas as the main fuel for its production process, which is supplied mainly by private suppliers using the pipelines that are the property of the Centro Nacional de Control del Gas Natural (“Cenagas”). In the first quarter of 2021, Braskem Idesa entered into a natural gas transport service agreement with Cenagas for a term of 15 years, which is in full force and effect. For additional information, see “Item 3.D Risk Factors—Risks Relating to Us and the Petrochemical Industry—We depend on ethane supplied by Pemex in Mexico,” “—We rely on limited or sole-source suppliers for our raw materials, inputs and energy, including transportation thereof” and “—Political and economic conditions and government policies in Mexico, including political interferences in state-owned companies such as Pemex and Cenagas, and elsewhere may have a material impact on our operations.” Our Mexico Segment uses hexene as a raw material in the production of HDPE. We import hexene for the Mexico Complex from suppliers located in the United States. Our Mexico Segment uses catalysts supplied by Ineos Europe Limited. Supply Contracts of the Mexico Segment Ethane Supply Agreement (with Pemex) Braskem Idesa is party to an ethane supply agreement with Pemex, dated February 19, 2010, based on commercial conditions (“BI’s Ethane Supply Agreement”). On September 27, 2021, Braskem Idesa signed the third amendment to the BI’s Ethane Supply Agreement (the “Amended ESA”). Upon effectiveness, the Amended ESA modified certain terms of the BI’s Ethane Supply Agreement, including: 89 Table of Contents · with respect to our Mexico Segment, Braskem Idesa agreed to reduce the contractual volume to be purchased on a deliver or pay basis from 66,000 to 30,000 barrels of ethane per day (“Contractual Volume”), until February 2025, provided that, such term may be extended in the event of a delay of obtaining permits not attributable to Braskem Idesa or TQPM. The term has been extended until February 2026, or until the ethane import terminal is constructed, commissioned and commercially operational. As of February 9, 2026, the contractual volume commitment under the Amendment expired, and the parties entered into a right of first refusal arrangement in favor of Braskem Idesa, without any minimum volume obligation. · with respect to our Mexico segment, once the term referred to in the paragraph above expires, Braskem Idesa will have a right of first refusal to acquire ethane that Pemex and its affiliates do not consume for their own processes or for the production of ethylene and derivative products, in a daily volume agreed by Braskem Idesa and Pemex; and · as stated under the Amended ESA, the revised term is 20 years starting from the commencement date of supply under the BI’s Equity Supply Agreement, which occurred in June 2015, with three periods of extension of ten years each, being the first extension period mandatory for Pemex and Braskem Idesa. Ethane Supply Agreement (for the Fast Track) On February 25, 2020, Braskem Idesa entered into an open order quantity agreement with Braskem Netherlands for the supply of liquid ethane with a minimum purity level of 95% in effect until 2021, the BNL Ethane Supply Agreement. (the “BI-BNL Ethane Supply Agreement”). On October 9, 2021, January 24, 2022, September 27, 2022, April 2023 and November 7, 2023 we entered into several amendments to the BI-BNL Ethane Supply Agreement (the “BI-BNL Ethane Supply Agreement Amendments”) in order to enhance the alternate ethane supply provided to us by the Fast-Track Solution. The purpose of the BI-BNL Ethane Supply Agreement Amendment is the additional acquisition of the supply volume of liquid ethane above the maximum amount of the BI-BNL Ethane Supply Agreement loaded from February 2021 to December 31, 2023. On December 18, 2023, Braskem Idesa entered into a term agreement for the sale of ethane with Braskem Netherlands, B.V., substituted on January 1, 2024 for Braskem Trading & Shipping B.V., in effect until March 2033 using Mont Belvieu price reference, in order to import: (i) additional capacity of ethane to the ethane currently supplied by Pemex before Ethane Import Terminal becomes fully operational; and (ii) all ethane requirements of Braskem Idesa after Ethane Import Terminal become operational. Storage and Transportation Services Agreement (with TQPM) On October 31, 2023 Braskem Idesa entered into a Storage Services Agreement and a Transportation Services Agreement with Terminal Química Puerto México S.A.P.I. de C.V. (“TQPM”), with a term of 20 years. Through these contracts, TQPM will be the responsible for receiving ethane at the Jetty 8 of Laguna de Pajaritos, which is part of the Terminal, unloading from the Braskem Idesa’s chartered vessels and storing it in cryogenic tanks. TQPM is also responsible for transport the ethane by a pipeline that will connect the terminal directly to our Mexico Complex. The ethane that TQPM will store and transport proceed from the long-term agreement between Braskem Idesa and Braskem Netherlands, B.V. On January 1, 2024, Braskem Netherlands, B.V. was replaced by Braskem Trading & Shipping B.V, as detailed on the above section. 90 Table of Contents Electricity and Water The Mexico Complex has its own power generation plant consisting of one gas turbine and two steam turbines, which can generate more than 100% of the Mexico Complex’s energy consumption. In addition, the Mexico Complex is also connected to the high-voltage power grid of Comisión Federal de Electricidad (the Mexican government-owned electricity company) as an alternative power source. The Mexico complex generates all of its requirements of steam and its water requirements are supplied by the Comisión Nacional del Agua (the Mexican government-owned water commission) pursuant to an agreement that expires in 2029 and is subject to renewal. The main feedstock used for power generation is natural gas, which is mainly supplied by private suppliers and Pemex through Cenagas. For additional information, see “Item 3.D Risk Factors—Risks Relating to Mexico—Political and economic conditions and government policies in Mexico, including political interferences in state-owned companies such as Pemex and Cenagas, and elsewhere may have a material impact on our operations.” Sales and Marketing of Our Mexico Segment For the year ended December 31, 2025, our Mexico Segment sold polyethylene products to 41 customers in the Mexican market and 32 customers abroad. We have a diversified product mix that allows us to serve a broad range of end users in several industries. The customers of our Mexico Segment generally are third generation petrochemical producers that manufacture a wide variety of plastic-based consumer and industrial goods. The following table sets forth our net revenue derived from sales of our Mexico Segment for the years indicated: For the Year Ended December 31, 2025 2024 2023 (in millions of reais) Net revenue: Mexico 4,103 5,148 4,449 Domestic Mexican Sales One of our priorities has been to develop long-term relationships with our customers and, given the cyclical nature of the markets for our polyethylene products, we believe that we can strengthen customer loyalty during periods of reduced demand for polyethylene by providing a reliable source of supply to these customers during periods of high demand. We work closely with our customers to determine their needs, to provide technical assistance and to coordinate the production and delivery of our products. Considering our Mexico Complex’s logistical infrastructure and logistics centers in different regions, we are able to forecast and respond faster to customer demand by region. Thus, we can anticipate and plan our production and logistics in order to make the products available on time and at the points of shipment. As our products portfolio can adjust to the nature of the demand of the Mexican market, we have greater flexibility to adapt and better serve the market. In addition to direct sales of polyethylene to our customers, our Mexico Segment sells products in Mexico through independent distributors. Our Mexico Segment is served by distributors through which we distribute our products pursuant to formal agreements and spot market transactions. We have selected our distributors based on their ability to provide full service to their customers, including the ability to prepare our products on a customized basis. These distributors sell our polyethylene products to manufacturers with lower volume requirements and are able to aggregate multiple orders for delivery to customers that would otherwise be uneconomical for us to serve. Furthermore, by serving smaller customers through a network of distributors, our account managers focus their efforts on delivering high quality service to a smaller number of large, direct customers. 91 Table of Contents Export Sales The main focus of our Mexico Segment is to maintain our leading position in the Mexican market while continuing to export in order to manage the relationship between our production capacity and domestic demand for our products. We believe that our continued presence in export markets is essential to help manage any overcapacity in the Mexican market. The excess volume is exported to several regions such North and South America, Asia, and Europe, using our existing sales force and complementing our portfolio in those regions, in order to use the already established Braskem sales channels in the United States and Europe (also in South America and traders in Asia), the strategy of exports of the Mexico Segment production, for these regions, is to develop and retain customers, in order to seek a greater added value in exports, especially considering the competitive logistics for serving the United States. This new polyethylene complex reinforces our position with polyethylene customers worldwide, which enhances our position in North America. Prices and Sales Terms We determine the Mexican domestic prices for polyethylene by reference to North American export prices. Our customers in Mexico may pay in full on delivery or elect credit terms that require payment in full within 60 days, on average, following delivery for most customers. Our Mexico Segment’s export sales consist of volumes to South America, Europe and the United States through traders and distributors. Pricing is based on international market price references. As discussed under “—Export Sales” above, since the beginning of 2017, the Mexico Segment has been focused on export sales directly to customers in the United States, Europe, Central America and the Caribbean and South America, so the price in the local of the sale, excluding the logistics costs to move the product until that place and the other variable costs, ex-raw material, of exports has been increasing. Competition We have the largest annual production capacity of polyethylene in Mexico, according to CMA. We compete in Mexico with a subsidiary of Pemex and with importers of polyethylene, primarily producers located in the United States and Canada. We compete for export sales of our polyethylene products with producers from other countries in Latin America and in markets in the United States, Latin America and Europe. Our export business is a commodity business, and we compete with a variety of resin producers, some of which have greater financial, research and development, production and other resources than us. Our competitive position in the export markets that we serve is primarily based on raw material costs, selling prices, product quality and customer service and support. Technology, Research and Development Research and Development Research and development (“R&D”) are key to developing a sustainable portfolio of solutions that address competitiveness, differentiation, carbon emission reductions and circularity. Our main priority is to enable growth through upgrade and development of new technologies to ensure business perpetuity. A close relationship with innovation eco-system, customers and market amplifies our ability to understand the current needs and anticipate future opportunities. We develop new technologies at our research and development centers: (1) Innovation and Technology Center in Triunfo, Rio Grande do Sul, Brazil; (2) Innovation and Technology Center in Pittsburgh, Pennsylvania, United States; (3) Braskem Laboratory for Biotechnology Development in Campinas, São Paulo, Brazil; (4) Process Technology Development Center in Mauá, São Paulo, Brazil; (5) European Technical Center in Wesseling, North Rhein Westphalia, Germany;(6) Mexican Technical Center in Nanchital, Vera Cruz, Mexico; and (7) Braskem Renewable Innovation Center, in Lexington, Massachusetts, United States, where we develop new processes, technologies, products and applications for many market segments. As of December 31, 2025, we had 352 employees dedicated to R&D. Through these centers, we coordinate and conduct our research and development activities that include scale-up (pilot plants operation), analytical testing, catalyst development and testing, advanced materials characterization, process technology development and research capabilities on renewable sources, biotechnology, recycling and decarbonization. 92 Table of Contents In 2025, we invested R$43.2 million (US$7.7 million) in innovation and technology CAPEX considering the infrastructure in the United States, Brazil and Europe, which includes resources that support the entire innovation pipeline, such as laboratory and industrial equipment, and structures necessary for project development. As part of the effort to improve our current product portfolio, several projects were carried out in 2025. In Brazil, initiatives include the optimization of resin grade portfolios, which reduced property variations during production campaigns, resulting in greater operational efficiency. A new bio-based HDPE was also developed for nonwoven applications, offering improved processability, higher thermal resistance, and excellent color stability. Another example of product improvements relate to Europe, where we launched a new PP copolymer with high optical transparency, designed for modified-atmosphere packaging (MAP). In the United States, part of the efforts focused on improving productivity and quality during transitions between different product runs, as well as enabling greater flexibility across different assets, which results in reduced losses and greater value for Braskem. Another important aspect of this type of initiative is the reduction of waste generation, aligned with our sustainability goals. Braskem believes that bio-revolution is one of the most promising paths toward building a more sustainable society. The large-scale use of biomass converted into lower-carbon products are expected to contribute to the measures established to mitigate the effects of climate change. Within the bio-based pillar, the projects aim to develop low-carbon chemical products at commercial scale, using renewable raw materials and sustainable processes, with a focus on achieving a negative carbon footprint. In 2025, we continued our partnership with Lallemand Biofuels & Distilled Spirits (LBDS), dedicated to the development of renewable chemicals. The laboratories located in Lexington, in the United States, and in Campinas, in Brazil, remain strategic centers for the development of technologies that will support the Compans in our long-term goal of carbon neutrality. The research conducted is focused on converting biomass-based raw materials into sustainable chemicals and materials. These initiatives reinforce Braskem’s role as a leader in renewable polymers and chemicals and reflect our ongoing commitment to innovation aimed at sustainability and at reducing dependence on non-renewable resources. Within the recycling pillar, we continue to advance in developing solutions that contribute to our long-term goals of eliminating plastic waste and increasing the use of recycled resins in high-performance applications. In 2025, new grades were launched, strengthening our portfolio of post-consumer recycled (PCR) resins. In the flexibles segment, our developments once again enabled the recovery of millions of plastic packages. In the rigids segment, we recorded important progress with the launch of new materials. Notable examples include the development of a high-flow PP PCR designed for injection-molded household items. We also launched a raffia-based PP grade for furniture injection, offering a sustainable and competitive alternative for the sector. Another highlight is the new HDPE grade for rotomolding, specially developed for garden pots, combining mechanical strength with excellent aesthetic finish. These developments open new opportunities for the use of PCR in demanding applications, bringing greater competitiveness, innovation, and environmental value to our customers. The metric currently used to evaluate Sustainable Innovation, the Sustainability Index (SI), is based on four qualitative pillars. Projects are classified as positive, neutral, or negative in sustainability and compared to the total number of projects in the pipeline. As a result, the actual impact or level of effort involved is not captured, given the differences in scope and impact across projects. Considering these limitations, we decided to introduce a new metric that better reflects the Company’s strategic priorities and the resources allocated to them. The new KPI will measure the global percentage of innovation resources directed toward projects with positive sustainability bias, such as bio-based initiatives and recycling technologies. 93 Table of Contents To calculate this metric, we will consider OPEX and CAPEX directly associated with bio-based and recycling projects. Using this methodology, the new metric indicates that 49% of our innovation capital is currently directed toward sustainability-focused projects. Maintenance Brazil and Mexico Most of our maintenance is performed by third-party service providers. For example, we have contracts with Siemens Energy, Asea Brown Boveri, General Electric, Tenenge– Montagem e Manutenção Ltda. (a subsidiary of Novonor S.A. – Em Recuperação Judicial.), Rip Serviços Industriais S.A, In Haus Industrial and other service providers to perform maintenance for our basic petrochemical plants and other units. Our maintenance strategy and planning are defined by our maintenance team while maintenance detailing and execution are primarily performed by contractors, with a small portion performed by our maintenance technicians. United States and Europe Most of our maintenance is performed by internal maintenance team members. We have contracts with many of the third-party companies identified for Brazil, but we do not use their personnel routinely. Our maintenance strategy, planning, and scheduling are defined by our maintenance team. The execution of our maintenance work is performed mainly by team members but can vary by site and by the required work. Chemicals Plants Regular chemicals plant maintenance requires complete plant shutdowns from time to time, and these shutdowns usually take 30 to 45 days to complete. We occasionally undertake brief shutdowns of the chemical operations at our basic petrochemical plants that do not materially affect our production output, primarily for maintenance purposes, catalyst regeneration and equipment cleaning. In addition, because we have two independent olefins units and two independent aromatics units at the Northeastern Complex and two independent olefins units at the Southern Complex, we may continue production of chemicals at these complexes without interruption, even while we perform certain maintenance services. The next scheduled general maintenance shutdown of: · the Southern complex’s olefins (Olefins II) and aromatics unit are scheduled to take place in 2027; and · the Southeast complex’s aromatics and olefins unit is scheduled to take place in 2028. Plants of Our Brazil, and United States and Europe Segment We have a regular maintenance program for each of our polyolefin plants. Production at each of our polyolefin plants generally is shut down for 15 to 30 days every 3 to 6 years to allow for regular inspection and maintenance. In addition, we undertake other brief shutdowns for maintenance purposes that do not materially affect our production of polyolefins. While our chemicals plants must be shut down for up to 45 days every 6 to 8 years for maintenance, our polyolefins plants may be shut down for shorter periods due to the smaller size and complexity of the assets when compared to chemical plants. We coordinate the maintenance cycles of our polyolefin plants located at Brazil and Mexico with those of our basic petrochemicals plants. Similarly, our polyolefins plants located in the United States and Europe attempt to coordinate their maintenance cycles with the routines of their largest suppliers. 94 Table of Contents We have a regular maintenance program for each of our vinyls plants. Our Northeast PVC plants are generally shut down for 15 to 35 days every two or three years to allow for regular inspection and maintenance. Environmental Regulation We, like other petrochemical producers, are subject to stringent federal, state and local environmental laws and regulations concerning human health, the handling and disposal of solid and hazardous wastes and discharges of pollutants into the air, water and soil, among others. Petrochemical producers are sometimes subject to unfavorable market perceptions as a result of the environmental impact of their business, which can have an adverse effect on their results of operations. Costs and capital expenditures relating to environmental, health or safety matters are subject to evolving regulatory requirements and will depend on the timing of the promulgation and enforcement of specific standards which impose the requirements. Compliance with Environmental Laws in Brazil The Brazilian government enacted an Environmental Crimes Law in 1998 that imposes criminal penalties on corporations and individuals causing environmental damage. Corporations found to be polluting can be fined up to R$50.0 million, have their operations suspended, be prohibited from government contracting, be required to repair damage that they cause and lose certain tax benefits and incentives. Executive officers, directors and other individuals may be imprisoned for up to five years for environmental violations. We make all reasonable efforts to ensure that our operations are in compliance in all material respects with applicable Brazilian environmental laws and regulations currently in effect. Our internal audit processes and our management system in place aim to ensure that the permits that will expire be renewed in a timely manner. However, changes to applicable laws and regulations may require us to revise our standards, which may take some time to implement. Some environmental studies that we have commissioned have indicated instances of environmental contamination at certain of our plants. In addition, we and certain of our executive officers have received notices from time to time related to minor environmental violations and are or have been subject to investigations or legal proceedings with respect to certain alleged environmental violations. These environmental issues, and any future environmental issues that may arise, could subject us to fines or other civil or criminal penalties imposed by Brazilian authorities. Operating Permits Under Brazilian federal and state environmental laws and regulations, we are required to obtain operating permits for our manufacturing plants. If any of our environmental licenses and permits lapse or are not renewed or if we fail to obtain any required environmental licenses and permits, we may be subject to fines ranging from R$500 to R$50 million, and the Brazilian government may partially or totally suspend our activities and impose civil and criminal sanctions on us. Each State in which we operate has its own environmental standards and state authorities have issued operating permits that must be renewed periodically. Additionally, all projects for the installation and operation of industrial plants in the Northeastern Complex, Southern Complex, São Paulo Complex, Rio de Janeiro Complex and Alagoas plants are subject to approval by various environmental protection agencies, which must approve installed projects prior to their commencement of operations and must renew such approval periodically thereafter. State authorities have issued operating permits for all of our plants, as follows: the Northeastern Complex (State of Bahia); Southern Complex (State of Rio Grande do Sul), São Paulo Complex, Cubatão and Paulínia plants (State of São Paulo), Rio de Janeiro Complex (State of Rio de Janeiro) and our Alagoas plants (State of Alagoas). We make all reasonable efforts to ensure that our operations in Brazil are in compliance in all material respects with applicable Brazilian federal, state, and local environmental laws and regulations currently in effect, and we have an internal audit process and a management system in place that help us ensure that the permits that will expire be renewed in a timely manner and that we are in compliance with the environmental laws and regulations. 95 Table of Contents Industrial Waste Grupo Aegea Saneamento, which controls CORSAN, a sanitation company, operates an integrated system for liquid effluents treatment, or Sitel, in the Southern Complex. Sitel treats wastewater generated by us and the other petrochemical producers at the Southern Complex at a liquid effluents treatment station located in the Southern Complex. This treatment station also includes a system for the collection of contaminated wastewater and disposal after treatment. We treat wastewater generated by us at the Rio de Janeiro Complex at a liquid effluent treatment station located in the Rio de Janeiro Complex. This treatment station also includes a system for the collection and disposal of contaminated wastewater. Hazardous solid waste is co-processed in cement kilns or incinerated and other kinds of solid waste are disposed of in landfills. We treat wastewater generated by us at the São Paulo Complex at a liquid effluent treatment station located in the São Paulo Complex. This treatment station also includes a system for the collection and disposal of contaminated wastewater. Hazardous waste generated at the São Paulo Complex is co-processed in cement kilns or incinerated and other kinds of solid waste are disposed of in landfills. In our Bahia plants, all wastewater is transported to the wastewater treatment facility at Cetrel. Hazardous liquid and solid waste are incinerated at high temperatures and non-hazardous solid waste is co-processed and sent to cement companies to be used as energy in cement kilns. Other kinds of solid waste are disposed of in landfills. In our Alagoas plants, organochlorines waste is incinerated, producing steam and wastewater. All wastewater is treated at a treatment station located in the complex. Solid waste is separated and disposed of in landfills. Additionally, we have a series of recycling programs that include recycling of solid waste and wastewater. As of December 31, 2025, we recycled or reused 51.0% of the solid waste generated by our plants and 27.8% of the water used in our production processes. Mercury As of April 8, 2020, our chlor-alkali plant in Bahia based on mercury cell technology shut down following the end of the facility’s useful life, and it has been decommissioned. The decommissioning strategy involves equipment decontamination/dismantling and proper waste disposal. In December 2023, the Company finalized the dismantling of the entire unit (except the areas of demercurization of effluents and solid waste) and disposing of its properly decontaminated waste. In compliance with applicable regulation (CONAMA No. 420), in 2024 all the phases for the environmental diagnosis of potentially contaminated areas (Preliminary Assessment, Confirmatory Investigation and Detailed Investigation) were completed. In 2025, a Human Health Risk Assessment for the area was initiated and is expected to be concluded in the first half of 2026. Also, in 2026 we expect to develop the remediation intervention plan for the facility. Compliance with Environmental Laws in the United States Our operations in the United States are subject to federal, state and local laws and regulations governing the discharge of effluents and emissions into the environment; the generation, storage, handling, management, transportation and disposal of hazardous waste, industrial waste and other types of waste; the use, storage, and handling of various types of products and materials; and the protection of human health, safety and the environment. Such laws include but are not limited to, the Clean Air Act, the Clean Water Act of 1970, the Toxic Substances Control Act (“TSCA”), the Comprehensive Environmental Response, Compensation and Liability Act (“CERCLA”), and the Resource Conservation and Recovery Act (“RCRA”), and their implementing regulations. Specific permits must be obtained to authorize certain types of operations, emissions or discharges. For example, our plants in Texas, Pennsylvania, and West Virginia are required to maintain various permits relating to air quality and treatment of industrial wastewater, and to comply with regulatory requirements relating to waste management. Our operations in the United States are in compliance in all material respects with applicable United States federal, state and local environmental laws and regulations currently in effect and, to the extent any operations are determined to experience any deviations from applicable requirements, we respond as is necessary under the circumstances and governing laws. 96 Table of Contents As with the U.S. petrochemical industry generally, costs associated with compliance with existing and anticipated laws and regulations increases the overall cost of operating our U.S. plants, including operating costs and capital costs to construct, maintain, and upgrade equipment and plants. These laws and regulations have required, and are expected to continue to require, expenditures of both a capital and an expense nature. The Clean Air Act, which was last amended in 1990, requires the United States Environmental Protection Agency, or the EPA, to set National Ambient Air Quality Standards (“NAAQS”) for pollutants considered harmful to public health and the environment. The Clean Air Act requires periodic review of the science upon which the standards are based and of the standards themselves. NAAQS for ozone and fine particulate matter (referred to as PM2.5) promulgated by the EPA have resulted in identification of nonattainment areas throughout the country, including certain areas within Texas, Pennsylvania, and West Virginia, where Braskem America operates plants. As a result of these nonattainment designations by the EPA, state or local air pollution control agencies are required to apply permitting and/or control requirements intended to reduce emissions of ozone precursors (nitrogen oxides and volatile organic compounds), and fine particles (including PM2.5 precursors) in order to demonstrate attainment with the applicable NAAQS. Such requirements may include imposition of offset requirements and could result in enhanced emission control standards. The last time the EPA reviewed the NAAQS for ozone was in 2020. At that time, the EPA determined to retain the current primary and secondary NAAQS for ozone of .070 ppm. On February 7, 2024, the EPA announced that it was significantly lowering the primary (health-based) annual NAAQS for PM2.5 from 12.0 µg/m3 to 9.0 µg/m3, however such action was promptly met with legal challenges from state and industry groups. Shortly thereafter, the EPA, under the new Trump administration, likewise filed a motion to vacate the 2024 standard, claiming a lack of legal authority. Although the new standard was set to take effect in February 2026, the rule’s future remains uncertain pending the resolution of the legal challenges before the D.C. Circuit Court of Appeals. If the rule is vacated, nonattainment designations and permitting for fine particulate matter would remain subject to the previous, less stringent standards. If the rule is upheld, any states in nonattainment with the new standard will be required to revise implementation plans to demonstrate what steps they will take to further reduce the concentration of PM2.5 in the ambient air to come into attainment, including through regulating PM2.5’s precursor pollutants. Such state-specific requirements would become applicable, if at all, following a multi-year process, because the plans require EPA approval. In turn, state regulations implementing changes consistent with the states’ revised implementation plans will likely not be promulgated for several years. In addition to permitting and/or control requirements that may result from the implementation of the NAAQS at the state or local level, the EPA may promulgate new or revised federal New Source Performance Standards or National Emission Standards for Hazardous Air Pollutants that would apply directly to certain facility operations and may require the installation or upgrade of control equipment in order to satisfy applicable emission limits and/or operating standards under these regulatory programs. 97 Table of Contents Additionally, there are various legislative and regulatory measures to address greenhouse gas emissions from coal-fired and oil-fired energy plants which are in various stages of review, discussion or implementation by Congress and the EPA. In early 2025, EPA Administrator Lee Zeldin, in response to direction from the Trump Administration, announced the EPA’s intention to reconsider many Clean Air Act regulations, including without limitation those aimed at reducing greenhouse gas emissions. At this stage, those rules have been proposed for recission, and the EPA has even proposed to withdraw the original greenhouse gas endangerment finding which served as the legal underpinning for many of the federal Clean Air Act regulations over the last decade or longer. While it is currently not possible to predict the final impact, if any, that these efforts may have on the affected regulations, nor on Braskem America or the U.S. petrochemical industry in general, if the EPA’s current proposals are finalized, any regulatory program that depends on greenhouse gases being classified as “pollutants” with the potential to impact public health under the Clean Air Act could be vulnerable. Vehicle and other manufacturing sectors have also invested heavily in technologies and compliance strategies built around existing standards, and rescission has the potential to disrupt long-term planning and product supply and demand. The final resolution of the EPA’s current broad deregulatory efforts could also result in increased utility costs to operate our plants in the United States if they remain in effect. The EPA’s regulations of electricity generating plants do not specifically apply to Braskem America’s operations but could have a collateral effect. Indeed, industry and private ratepayers alike are already experiencing spiking electricity costs. In addition, potential future regulations limiting greenhouse gas emissions of carbon content of products, which target specific industries such as petrochemical manufacturing could adversely affect our ability to conduct Braskem America’s business and also may reduce demand for its products. Also relevant to Braskem America is the 2024 final rule entitled “Accidental Release Prevention Requirements: Risk Management Programs Under the Clean Air Act; Safer Communities by Chemical Accident Prevention (the “RMP Rule”). Unlike the utility-sector rules discussed above, the RMP Rule does apply to certain of Braskem’s operations in the United States. The RMP Rule was originally scheduled to take effect in 2025, however the EPA later announced that it would undertake a new rulemaking process to reassess the requirements in the RMP Rule in light of the Trump Administration’s policy priorities. Most recently, the EPA stated that it intended to finalize a new RMP rule later than anticipated, sometime in “late 2026.” Accordingly, the regulated industry should expect to see a proposed rule revising or rescinding certain of the requirements from the 2024 rule in early 2026. For now, however, the 2024 rule remains in effect. Compliance with Environmental Laws in Mexico Braskem Idesa in Mexico is subject to federal, state and local laws and regulations that govern the discharge of effluents and emissions to the environment; the generation, storage, handling, management, transportation and disposal of hazardous waste, industrial waste and other types of waste; the use, storage and handling of various types of products and materials; and the protection of human health, safety and the environment. Specific permits may be required for certain types of operations. Ethylene and Aromatic Hydrocarbons Mixture production require permission of the Secretary of Energy and Federal Commission for Sanitary Risks (COFEPRIS) related to risk management and public health, The Mexican legislation regulates the emission of particles, ozone, fixed sources and everything related to GHGs. There are regulations on water, effluent treatments and specific conditions for discharge of the effluent. Our operations in Mexico are in compliance in all material respects with applicable Mexican federal, state and local environmental laws and regulations currently in effect. In Mexico, the Federal Attorney’s Office for Federal Environmental Protection (PROFEPA) verifies compliance with the Mexican Regulation and Permits through audits. Failure to comply with Mexican regulations may lead to economic and administrative penalties, including Operations shutdown in certain cases. 98 Table of Contents Compliance with Environmental Laws in Germany and the European Union Our operations in Germany are subject to German federal, state and local laws and regulations governing the discharge of effluents and emissions into the environment and the handling and disposal of industrial waste and otherwise relating to the protection of the environment and waste management. Our operations in Germany are in compliance in all material respects with applicable German federal, state and local environmental laws and regulations currently in effect. As with the petrochemical industry in the European Union generally, compliance with existing and anticipated German laws and regulations increases the overall cost of operating our European business, including operating costs and capital costs to construct, maintain and upgrade equipment and plants. These laws and regulations have required and are expected to continue to require us to make expenditures of both a capital and an expense nature. At our Schkopau and Wesseling plants in Germany, we are required to maintain air, radiation, waste water and waste management permits. We are in possession of all necessary permits. Furthermore, our Wesseling and Schkopau plants in Germany are subject to existing European GHG regulations and a cap-and-trade program relating to emissions. We have purchased sufficient carbon dioxide emissions permits for our operations until the end of 2025, provided we operate under normal business conditions. We will purchase any additional permits that may be required on the emission trade market. We are not aware of any new environmental regulations that would materially affect our European operations. Accordingly, we cannot estimate the potential financial impact of any future European Union or German environmental regulations. Sustainability In April 2018, our board of directors approved our policy on global sustainable development. Its objective is to encourage economic growth, environmental preservation and social justice by developing sustainable solutions related to chemical and plastic production. In connection with these objectives, we have developed a three-pronged approach: (1) seek and develop sustainable sources and operations, (2) develop and deliver a portfolio of sustainable products and services, and (3) work with our clients to offer sustainable solutions that benefit society as a whole. Circular Economy Consistent with our purpose of contributing to the transition from a linear economy into a circular economy, effectively demonstrating our commitment to sustainable development, we announced our long-term ESG goals in 2019. This commitment, which evolved in 2020 into a carbon-neutral circular economy, positions Braskem as part of the solution, working with all interested parties to transform the linear economy into a circular one, where society’s needs are met by more innovative and sustainable materials, processes, and systems. The initiatives include offering recycled content solutions to our clients, developing recycling technologies and innovation, engaging consumers through educational actions on conscious consumption and proper disposal, as well as supporting our clients to design more sustainable packaging. Property, Plant and Equipment Our properties consist primarily of petrochemical production plants in: · Camaçari, in the State of Bahia, Brazil; · Triunfo, in the State of Rio Grande do Sul, Brazil; 99 Table of Contents · Duque de Caxias, in the State of Rio de Janeiro, Brazil; · Paulínia, Cubatão, Santo André and Mauá, in the State of São Paulo, Brazil; · Maceió and Marechal Deodoro, in the State of Alagoas, Brazil; · La Porte, Freeport and Seadrift, in the State of Texas, United States; · Marcus Hook, in the State of Pennsylvania, United States; · Neal, in the State of West Virginia, United States; · Schkopau and Wesseling, in Germany; and · Coatzacoalcos, in Mexico. For more information, see note 11 to our audited consolidated financial statements included elsewhere in this annual report. Our principal executive offices are located in São Paulo, in the State of São Paulo, and we have an administrative support office in the City of Salvador, in the State of Bahia, Brazil, in Philadelphia, in the State of Pennsylvania, in the United States, and in Rotterdam, in Netherlands. We also have equity interests in investments located in other countries. We own all of our production plants, but we generally lease our administrative offices. The following table sets forth our properties as of December 31, 2025, by location of plants, products produced and size of plant. Type of Product Location of Plants Size of Plant Product Country State City (in hectares)(1) Chemicals Brazil Rio Grande do Sul Triunfo 153 Chemicals Brazil Bahia Camaçari 137 Chemicals Brazil São Paulo Santo André 72 Chemicals/Polyethylene Brazil Rio de Janeiro Duque de Caxias 56 Chemicals Mexico Veracruz Coatzacoalcos 24 Polyethylene Brazil São Paulo Cubatão 86 Polyethylene Brazil Rio Grande do Sul Triunfo 80 Polyethylene Brazil Bahia Camaçari 38 Polyethylene Brazil São Paulo Santo André 17 Polyethylene Mexico Veracruz Coatzacoalcos 15 Polypropylene United States Texas La Porte 87 Polypropylene Brazil Rio Grande do Sul Triunfo 43 Polypropylene Brazil São Paulo Paulínia 40 Polypropylene United States West Virginia Neal 27 Polypropylene Germany North Rhine-Westphalia Wesseling 26 Polypropylene Brazil São Paulo Mauá 20 Polypropylene Brazil Rio de Janeiro Duque de Caxias 15 Polypropylene United States Texas Freeport 9 Polypropylene United States Pennsylvania Marcus Hook 7 Polypropylene Germany Saxony-Anhalt Schkopau 4 Polypropylene United States Texas Seadrift 3 Caustic soda/chlorine(2) Brazil Alagoas Maceió 34 PVC Brazil Alagoas Marechal Deodoro 74 PVC/caustic soda(3)/chlorine(3) Brazil Bahia Camaçari 13 (1) One hectare equals 10,000 square meters. (2) In September 2025, the Company has decided to hibernate its last chlor-alkali unit, located in Maceió, state of Alagoas. The decision was part of the long-term strategy to improve competitiveness and better serve customers. (3) In January 2020, Braskem announced the permanent shutdown of its chlor-alkali production facility located in Camaçari, in the State of Bahia. The shutdown is explained by the end of the facility’s useful life and started in April 2020, following the applicable safety standards and seeking to protect people, local communities and the environment. 100 Table of Contents We believe that all of our operating plants are in good operating condition. As of December 31, 2025, the consolidated net book value of our property, plant and equipment was R$37,579 million. Certain of our chemicals plants, our polyethylene plant and our polypropylene plant located in the Rio de Janeiro Complex had been mortgaged to secure certain of our financial transactions, which were already paid off, and the mortgage liens are expected to be released Insurance In addition to the policies described below for our Brazilian and international operations, we maintain other insurance policies for specific risks, including general and product liability, environmental liability, directors and officers liability, workers’ compensation, domestic and international credit operations, marine cargo and charterers’ liability insurance, among others. We believe that our insurance coverage is reasonable in amount and consistent with industry standards applicable to chemical companies operating globally. Operations in Brazil, Mexico, the United States and Germany We carry insurance for all our plants against property damage and consequent business interruption through comprehensive “all risk” insurance policies. This insurance program is underwritten through separate policies in Brazil, Mexico, the United States and Germany by large insurance companies. The leading insurers are Mapfre (rating S&P A-), and Inbursa (rating S&P BBB). These policies are valid until April 2026. Set forth is a table with additional information related to our all-risk insurance policies. Policy / Region US$ bn Value at risk — P D + BI (1) Indemnity Limit PD + BI(1) Brazil(2) 30.4 3.9 Mexico(2) 5.1 1.9 United States and Germany(2) 5.2 1.2 (1) PD = Property Damage; BI = Business Interruption. (2) Includes coverage for acts of terrorism up to US$450 million limit for property damage. Our policies provide coverage for losses that arise from accidents caused by or resulting from fire, explosion, and machinery breakdown, among others, and consequential business interruption, with maximum indemnity periods ranging from 12 to 33 months, depending on the plant and/or coverage. 101 Table of Contents New projects can be covered for construction/erection all risks under the existing Property policies or through a standalone project-specific policy. We are exposed to operational risks, and our insurance policy requires coverage to be contracted through a complex insurance program involving multiple insurers and reinsurers in the commercial market, which have limited and variable capacity to offer insurance policies over time. In order to seek alternatives for the composition of hedges, the possibility of transferring operational risks through the mutual insurer “Everen” was identified. Everen is a global leader in the energy sector, including oil and gas, refining, chemical and petrochemicals, electric power and mining and has a portfolio of selected participants. In addition to providing a stable capacity to Braskem, Everen has a structure in which there is reciprocal cooperation among the insured companies participating in a known risk environment, in addition to a lower administrative cost compared to the commercial insurance market, providing less volatile and potentially competitive insurance premium. Compliance We have a Global Compliance System supported by a Code of Conduct, a Compliance System Policy, an Anti-corruption Policy and a series of internal directives that guide management, employees and counterparties, reinforcing the Company’s ethical principles and standards of professional conduct. As part of this structure, the Company maintains an independently managed Ethics Line available for employees and non-employees. Every whistleblower report is impartially investigated by an independent team, and the results, along with subsequent action plans, are communicated to the Ethics Committee and the Statutory Compliance and Audit Committee. This governance foundation has been consistently validated over the years. In March 2020, based on the certification report issued by independent monitors who oversaw the Company for three years, Brazil’s Federal Prosecutor’s Office (MPF) confirmed the conclusion of its monitoring, attesting to the effectiveness of Braskem’s compliance program and compliance with the MPF Agreement. Shortly afterward, on May 13, 2020, both the U.S. Department of Justice (DoJ) and the Securities and Exchange Commission (SEC) confirmed the end of their respective monitoring processes. The Brazilian Office of the Comptroller General (CGU) later concluded its monitoring of the Compliance Program on August 14, 2023. Since 2021, the Company has held certification under ISO 37001 – Anti-bribery Management Systems, granted by an external auditor accredited by INMETRO. QMS Certification has been responsible for auditing Braskem in both the 2021–2023 and the 2024–2025 certification cycles, confirming that its anti-bribery management system complies with the standards established by the International Organization for Standardization (ISO). The Company’s commitment to integrity has also been reflected in external evaluations and global initiatives. Braskem has consistently performed above the sector average in Instituto Ethos’ Integrity, Corruption Prevention and Combat Indicator, demonstrating the solidity of its Global Compliance System. In 2023, the Company joined Transparency 100%, an initiative of the UN Global Compact aimed at promoting corporate transparency in Brazil, further reinforcing its public commitments to ethical and responsible business practices. Building on this foundation, 2025 marked a step in the transformation of Braskem’s Compliance System. Aligned with the Company’s strategic direction, Braskem optimized practices, reviewed processes and consolidated activities globally. The resulting integrated structure expanded beyond the Compliance function to include key corporate areas such as Finance—responsible for Internal Controls and Risk Management—thereby enhancing the system’s corporate perspective and reinforcing its established consistency and maturity. As part of this transformation, the Company reviewed and updated its main normative documents, which govern topics such as risk management, procurement, sales, internal controls, internal audit, corporate credit card use, delegation of authority, due diligence, conflicts of interest, business courtesies, investigations, sponsorships and donations, travel management, interactions with public agents and related-party transactions. These revisions reflect process optimization and alignment with global best practices. 102 Table of Contents ITEM 4.A UNRESOLVED STAFF COMMENTS Not Applicable.

Our actual results may differ materially from those discussed in the forward-looking statements as a result of various factors, including those set forth in “Cautionary Statement with Respect to Forward-Looking Statements” and “Item 3. Key Information—Risk Factors.” Overview Our results of operations for the years ended December 31, 2025, 2024 and 2023 have been influenced, and our results of operations will continue to be influenced, by a variety of factors, including: · GDP growth in the regions where we operate, including as follows: o Brazil’s GDP grew 2.3% in as reported by the IBGE in March 2026, as compared to 3.4% in 2024 and 3.1% in 2023, which affected the demand for our products and, consequently, our sales volume; o the U.S. GDP grew 2.1% in 2025 as reported by U.S. Bureau of Economic Analysis in April 2026, as compared to 2.8% in 2024 and 2.5% in 2023, which affected the demand for our products and, consequently, our sales volume; o the Euro Area’s GDP grew 1.5% in 2025, as published by Eurostat in April 2026, as compared to 0.9% in 2024 and 0.4% in 2023, which affected the demand for our products and, consequently, our sales volume; o Mexico’s GDP grew 0.8% in 2025, as informed by INEGI in Aprl 2026, as compared to 1.4% in 2024 and 3.2% in 2023, which affected the demand for our products and, consequently, our sales volume; and o according to the IMF, the world’s GDP is expected to expand 3.4% in 2025, as compared to 3.4% in 2024 and 3.3% in 2023; it is projected to expand 3.1% in 2026. · the expansion or contraction of global production capacity for the products that we sell; 103 Table of Contents · the international market price of naphtha ARA, one of our main raw materials, expressed in U.S. dollars, which has a significant impact on the cost of producing our products and which experienced a high level of volatility during the year ended December 31, 2025, fluctuating in a range between US$505 and US$654 per ton during such period, compared to fluctuation in a range between US$612 and US$710 per ton during 2024; · the international market price of propylene in the United States, one of our main raw materials, expressed in U.S. dollars, which has a significant impact on the cost of producing our products and which experienced a high level of volatility during the year ended December 31, 2025, fluctuating in a range between US$672 and US$1,058 per ton during such period, compared to fluctuation in a range between US$860 and US$1,279 per ton during 2024; · the average Brazilian prices of resins expressed in U.S. dollars, which fluctuate to a significant extent based on international prices for these products and which also have a high correlation to our raw material costs; our crackers’ average capacity utilization rates, which in 2025 were lower (4 p.p.) when compared to 2024, explained mainly by (i) the adjustments of production levels in the face of lower demand in the period; and (ii) the scheduled maintenance shutdown at the Bahia petrochemical plant completed in January 2026; · government industrial policies in the countries and regions in which we operate; · changes in the real/U.S. dollar exchange rate, including the appreciation of the real against the U.S. dollar by 11% in 2025, the depreciation of 27.9% in 2024 and the appreciation of 7.2% in 2023. · the level of our outstanding indebtedness and fluctuations in benchmark interest rates in Brazil, which affect our interest expenses on our real-denominated floating rate debt and financial income on our cash and cash equivalents, and fluctuations in the SOFR rate, which affect our interest expenses on our U.S. dollar-denominated floating rate debt; · the inflation rate in Brazil, which was 4.4% in 2025, as measured by the IBGE (Índice Nacional de Preços ao Consumidor Amplo, or “IPCA”), and the effects of inflation on our operating expenses denominated in reais and our real-denominated debt that is indexed to consider the effects of inflation or bears interest at rates that are partially adjusted for inflation; and · tax policies and tax obligations. Our financial condition and liquidity are influenced by various factors, including: · our ability to generate cash flows from our operations; · prevailing Brazilian and international interest rates and movements in exchange rates, which affect our debt service requirements; · our ability to continue to be able to borrow funds from international and Brazilian financial institutions and to sell our debt securities in the international and Brazilian securities markets, which is influenced by a number of factors discussed below, including the adverse effect of any pandemic on the world economy and our business, financial condition and results of operations; · our capital expenditure requirements, which consist primarily of maintenance of our operating plants, expansion of our production capacity and research and development activities; and 104 Table of Contents · the requirement under Brazilian law and our by-laws that we pay dividends on an annual basis in an amount equal to at least 25% of our adjusted net income (calculated as net income for the financial year, after absorption of accumulated losses and for reserves, including legal reserves, pursuant to applicable law, or “Adjusted Net Income”), unless our board of directors, in accordance with applicable law, reports to our annual shareholders’ meeting that the distribution would be incompatible with our financial condition at that time, provided that payment of any minimum preferred dividends is not affected. Our fiscal council must opine on any suspension of the mandatory distribution. Recent Developments In January 2026, the Company became aware of the filing of a Public Civil Action by the Public Defender’s Office and the Association of Entrepreneurs and Victims of Braskem, seeking compensation for material and moral damages allegedly suffered by entrepreneurs operating businesses in the border area of the map. Additionally, as a preliminary injunction, the plaintiffs request the creation of an emergency support fund for entrepreneurs, with an initial contribution of R$400 million thousand by Braskem to subsidize loans for the benefit of the entrepreneurs. The plaintiffs assigned a value of R$2 billion to the claim. Based on the opinion of its external legal counsel, the Company classifies the likelihood of loss in this action as possible. In the first quarter of 2026, the Company was notified of two new tax assessments totaling R$1.2 billion, relating to various federal taxes offset against non-cumulative PIS and COFINS credits generated as a result of the exclusion of ICMS from the calculation bases of such contributions. Based on the opinion of its external legal counsel, the Company assesses the likelihood of loss in these actions as possible. On April 19, 2026, the Company received a correspondence from Novonor S.A. – Em recuperação Judicial ("Novonor"), NSP Investimentos S.A. ("NSP Inv."), and Shine I Fundo de Investimento em Participações Responsabilidade Limitada ("FIP"), communicating, among other matters, the execution of a Judicial Share Purchase and Sale Agreement and Other Provisions (Contrato de Compra e Venda Judicial de Ações e Outras Avenças) entered into among Novonor, NSP Inv., the FIP, and Shine I Fundo de Investimento em Direitos Creditórios Responsabilidade Limitada, investment funds managed by Vórtx Capital Gestora de Recursos Ltda. and advised by IG4 Sol Ltda., regulating, among other things, the terms and conditions for the judicial sale by NSP Inv. to the FIP of common shares and Class “A” preferred shares issued by Braskem, representing approximately 50.1% of the Company’s common shares and approximately 34.3% of its total share capital, in exchange for specified NSP Inv debentures to be delivered by the FIP to NSP Inv. The transaction is subject to conditions precedent, including required judicial and antitrust approvals and Petrobras’s non-exercise of its preemptive and tag-along rights, and the buyer is required to file for registration of a public tender offer for up to all outstanding Braskem shares on the same terms as the transaction. Upon closing, a new shareholders’ agreement between the buyer and Petrobras is expected to govern the exercise of shared control of Braskem. Financial Presentation and Accounting Policies Presentation of Financial Statements We have prepared our audited consolidated financial statements as of December 31, 2025, and 2024 and for each of the years ended December 31, 2025, 2024 and 2023 in accordance with IFRS Accounting Standards as issued by the International Accounting Standards Board (“IFRS Accounting Standards”). Operating Segments and Presentation of Segment Financial Data As of December 31, 2025, our business operations were organized into three segments, which corresponded to our principal production processes, products and services. Our reportable segments were as follows: · our Brazil Segment, which includes: (i) production and sale of chemicals at the petrochemical complex located in Camaçari, in the State of Bahia, or the Northeastern Complex, the Petrochemical complex located in Triunfo, in the State of Rio Grande do Sul, or the Southern Complex, the Petrochemical complex located in Capuava, in the State of São Paulo, or the São Paulo Complex and the petrochemical complex located in Duque de Caxias, in the State of Rio de Janeiro, or the Rio de Janeiro Complex; (ii) supply of electricity and other inputs produced in these complexes to second-generation producers located in the petrochemical complexes; (iii) production and sale of PE, including the production of PE I’m green™ bio-based from renewable resources, and PP produced by us in Brazil; and (iv) our production and sale of PVC; 105 Table of Contents The Brazil Segment accounted for net revenue of R$51,774 million, including exports from Brazil, or 72% of our consolidated net revenue of all reportable segments; · our United States and Europe Segment, which includes our production, operations and sale of polypropylene in the United States and Germany. This segment accounted for net revenue of R$16,400 million, or 23% of our consolidated net revenue of all reportable segments; and · our Mexico Segment, which includes our production, operations and sale of ethylene, HDPE (high-density polyethylene) and LDPE (low-density polyethylene) in Mexico. This segment accounted for net revenue of R$4,103 million, or 6% of our consolidated net revenue of all reportable segments. In 2025, 2024 and 2023, 60%, 58% and 57% of our net revenue, respectively, related to sales performed in Brazil, and 40%, 42% and 43% of our net revenue in 2025, 2024 and 2023 was derived from our international operations. Principal Factors Affecting Our Results of Operations Macroeconomic Environment in the Countries in which we Operate and Demand for Our Products Our sales in Brazil and exports from Brazil represented 72% of our net revenue of all of our reportable segments in the year ended on December 31, 2025. We are significantly affected by economic conditions in Brazil and in the other countries in which we operate, and our results of operations and financial condition have been, and will continue to be, affected by the growth or contraction rates of the GDP of Brazil, the United States, Europe and Mexico, and by global growth or contraction rates. The following table shows the GDP (growth/reduction), inflation, interest rates and exchange rate data for Brazil as of and for the periods indicated. December 31, 2025 2024 2023 2022 2021 GDP growth / reduction(1) 2.3% 3.4% 3.1% 2.9% 5.0% Inflation (IGP-M)(2) (1.0)% 6.5% (3.2)% 5.5% 17.8% Inflation (IPCA)(3) 4.3% 4.8% 4.6% 5.8% 10.1% CDI rate(4) 14.9% 11.8% 11.9% 13.7% 8.8% (Appreciation) depreciation of the real vs. U.S. dollar (11)% 27.9% (7.2)% (6.5)% 7.4% Period-end exchange rate—US$1.00 R$5.5024 R$6.1923 R$4.8413 R$5.2177 R$5.5805 Sources: (1) Brazilian GDP measured according to Sistema IBGE de Recuperação Automática SIDRA. (2) Inflation measured according to the general market price index (Índice Geral de Preços-Mercado) (IGP-M) by Fundação Getúlio Vargas. (3) Inflation measured according to the national broad consumer price index (Índice Nacional de Preços ao Consumidor Amplo) (IPCA) by the IBGE. (4) The CDI rate is the average of inter-bank overnight rates in Brazil (as of the last date of the respective period). 106 Table of Contents Brazilian GDP growth has fluctuated significantly, and we believe that it will likely continue to do so. Our management believes that the impact on growth in Brazil will positively affect our future net revenue and results of operations, and a continued recession or low growth in Brazil would likely reduce our future net revenue and have a negative effect on our results of operations. According to the IMF, the global economy is resilient and should remain stable, amid disinflation progress. The world’s GDP expanded 3.3% in 2023 and 3.4% in 2024 and is expected to reach 3.4% in 2025 and 3.1% in 2026. Effects of Fluctuations in Exchange Rates between the Real and the U.S. Dollar Our results of operations and financial condition have been, and will continue to be, affected by the rate of depreciation or appreciation of the real against the U.S. dollar because: · a substantial portion of our net revenue is denominated in or linked to U.S. dollars; · our costs for our raw materials and certain catalysts required in our production processes, are incurred in U.S. dollars or are linked to U.S. dollars; · we have operating expenses, and make other expenditures, that are denominated in or linked to U.S. dollars; and · we have significant amounts of U.S. dollar-denominated liabilities that require us to make principal and interest payments in U.S. dollars. Virtually, all of our sales are of petrochemical products for which there are international market prices expressed in U.S. dollars. We generally attempt to set prices that consider (1) the international market prices for our petrochemical products, and (2) in Brazil, variations in the real/U.S. dollar exchange rate. As a result, although a significant portion of our net revenue is denominated in reais, substantially all of our products are sold at prices that are based on international market prices that are quoted in U.S. dollars. Fluctuations in the real will affect the cost of naphtha, ethylene, propane, propylene and other U.S. dollar-linked or imported raw materials. The prices of raw materials that are under all of Petrobras’ contracts are linked to the U.S. dollar. The pricing formula includes a factor that adjusts the price to reflect the real/U.S. dollar exchange rate variations. The depreciation of the real against the U.S. dollar generally increases the production cost for our products and we generally attempt to increase the Brazilian prices for our products in reais (to the extent possible in light of then-prevailing market conditions in Brazil), which may result in reduced sales volumes of our products. To the extent that our price increases are not sufficient to cover the increased costs for raw materials, our gross profit decreases. Conversely, the appreciation of the real against the U.S. dollar generally decreases the production cost for our products and we generally decrease the Brazilian prices for our products in reais, which may result in increased sales volumes of our products. In periods when the real/U.S. dollar exchange rate is highly volatile, there is usually a lag between the time when the U.S. dollar appreciates or depreciates and the time when we are able to pass on increased costs, or are required to pass on reduced costs, in reais to our customers in Brazil. These pricing discrepancies decrease when the real/U.S. dollar exchange rate is less volatile. Braskem can enter into financial derivatives transactions to mitigate exchange rate risk associated with exposure to costs in reais. Those operations can include call and put options and related strategies. For example, Braskem may apply a hedging strategy referred to as collar, which is composed of the purchase of a put option associated with the simultaneous sale of a call option, where both options having the same maturity. In this case, if the real depreciates and the exchange rate on the exercise date of the option exceeds the exercise price of the call option, we may incur significant financial losses. However, since those strategies will be implemented only for non-speculative purposes (in accordance with our financial policy), potential losses on derivatives transactions should be offset by more competitive fixed costs in reais. 107 Table of Contents Our consolidated U.S. dollar-denominated indebtedness represented 93.7% of our outstanding indebtedness as of December 31, 2025, including our debt related to Braskem Idesa. Excluding it, our consolidated U.S. dollar-denominated indebtedness represented 91.9% of our outstanding indebtedness as of December 31, 2025. As a result, when the real depreciates against the U.S. dollar: · the interest costs on our U.S. dollar-denominated indebtedness increase in reais, which adversely affects our results of operations in reais; · the amount of our U.S. dollar-denominated indebtedness increases in reais, and our total liabilities and debt service obligations in reais increase; and · our financial expenses tend to increase as a result of foreign exchange losses that we must record, mitigated by our decision to designate, on May 1, 2013, October 10, 2017, February 1, 2019, May 2, 2019, November 1, 2019, January 2, 2020, March 1, 2021, September 1, 2022, October 1, 2023, November 1, 2024, April 30, 2025 and July 1, 2025 as part of our U.S. dollar-denominated liabilities as a hedge for our future exports. This hedge program was prospectively discontinued as of December 2025. Export sales and sales by our United States and Europe Segment, which enable us to generate receivables payable in foreign currencies, tend to provide a hedge against a portion of our U.S. dollar-denominated debt service obligations, but they do not fully match them. To minimize our accounting foreign exchange exposure, we apply hedge accounting, in accordance with IFRS 9. We designate certain derivative financial instruments and financial liabilities of debt denominated in US dollar as hedging instruments to protect against cash flow variability. Cash flow hedges are intended to protect against exposure to cash flow variability that is attributable to foreign exchange risk associated with future sales, considered highly probable at the time of designation. As the items subject to hedge affect profit or loss, the effective portions of the hedging strategy accumulated in the hedge reserve are reclassified to profit or loss at the same time the object is recognized. Given the substantial doubt about our ability to continue as a going concern, Management reassessed, for accounting purposes, the fulfillment of the “highly probable transactions” criterion required under IFRS 9 for the continuation of its hedge accounting program, which resulted in the prospective discontinuation, as of December 31, 2025, of the hedge accounting related to certain future revenues of Braskem S.A. The real/U.S. dollar exchange rate varied significantly over time. The real depreciated against the U.S. dollar from mid-2011 to early 2016, and again from early 2018 to 2020. As of December 31, 2020, the real/U.S. dollar exchange rate reported by the Central Bank was R$5.1967 per US$1.00, as of December 31, 2021, the real/U.S. dollar exchange rate reported by the Central Bank was R$5.5805 to US$1.00, as of December 31, 2022, the real/U.S. dollar exchange rate reported by the Central Bank was R$5.2177 to US$1.00, as of December 31, 2023, the real/U.S. dollar exchange rate reported by the Central Bank was R$4.8413 to US$1.00 as of December 31, 2024, the real/U.S. dollar exchange rate reported by the Central Bank was R$6.1923 to US$1.00 and as of December 31, 2025, the real/U.S. dollar exchange rate reported by the Central Bank was R$5.5024 to US$1.00. There can be no assurance that the real will not depreciate or appreciate further against the U.S. dollar. Effects of Brazilian Inflation Brazilian inflation affects our financial performance by increasing some of our operating expenses denominated in reais (and not linked to the U.S. dollar). A significant portion of our cost of products sold, however, are denominated in or linked to the U.S. dollar and are not substantially affected by the Brazilian inflation rate. Some of our real-denominated debt is indexed to take into account the effects of inflation. Under this debt, the principal amount generally is adjusted with reference to the Extended National Consumer Price Index (Índice Nacional de Preços ao Consumidor Amplo, or “IPCA”), an inflation index, so that inflation results in increases in our financial expenses and debt service obligations. In addition, a portion of our real-denominated debt bears interest at the CDI rate, which is partially adjusted for inflation. 108 Table of Contents Effect of Sales outside Brazil on Our Financial Performance We have significant production capacity located outside of Brazil from our plants located in the United States, Germany, and Mexico. During the year ended December 31, 2025, 39.9% of our net revenue was derived from sales of our products outside Brazil as compared to 42.3% during 2024 and 43.2% during 2023. Sales outside Brazil are important to us for diversification purposes in relation to regional supply and demand balance, macroeconomic factors, and the political environment. In line with our strategy, sales outside Brazil affect our financial performance by hedging our operations against risks linked to Brazil. In 2025, the world economy was impacted by a combination of protectionism, tariff wars, and persistent trade tensions, which reinforces global uncertainty. The year was marked by tariff increases in the United States, resulting in greater trade tensions, raising operating costs, fragmenting global supply chains and reducing investments. At the same time, the international scene continued to be pressured by conflicts such as the conflict involving Russia and Ukraine and the conflict between Israel and Gaza. This combination of factors has intensified global economic fragmentation, put pressure on financial markets, and limited growth potential. Petrochemical Cycles and Disruptive Scenarios Historically, the global petrochemical market has experienced alternating periods of limited supply, leading to the increase of global prices and profit margins, followed by periods of capacity additions, which puts downward pressure on utilization rates, global prices, and consequently operating margins, until demand catches up again, with new levels of product availability. This economic scenario is known as the petrochemical cycle. Sales of petrochemicals and chemical products are linked to the global demand and production levels (supply x demand), which may be affected by macroeconomic factors, such as interest rates, oil prices, shifts to alternative products, innovation, consumer trends, regulatory and legislative oversight requirements, trade agreements, as well as disruptions, pandemics, or other global events. Therefore, our results are influenced not only by our activities but also by the industry and macroeconomic scenarios, over which we have no control, and which may adversely affect our results of operations. However, sometimes new opportunities emerge from externalities, such as the shift in consumer behavior. An example derived from COVID-19 is that, from 2020 to 2022, a large part of the population shifted to home-office working, and therefore, increased the demand for several segments, such as packaging, healthcare, and construction. We believe that this outcome resulted in a less pronounced downward movement in the petrochemical industry. These cyclical trends in international selling prices and operating margins, relating to global capacity shortfalls and additions, will likely persist, mostly due to the continuity of four general factors: · cyclical trends in general business and macroeconomic activity produce swings in demand for petrochemicals; · during periods of reduced demand, the high fixed cost structure of the petrochemicals industry generally leads producers to compete aggressively on price in order to maximize capacity utilization; 109 Table of Contents · significant capacity additions, whether through plant expansion or construction, can take three to four years to be implemented and are therefore necessarily based upon estimates of future demand; and · as competition in petrochemical products is, in most cases, focused on commodities prices, being a low-cost producer is critical to improved profitability. This favors producers with larger plants that maximize economy of scale, but construction of plants with high capacity may result in significant increases in capacity that can outstrip demand growth for a period of time. During 2025, three structural changes or supply shocks have impacted the global market dynamics, namely: (i) the competitiveness of natural gas and ethane in the United States and the Middle East, which boosted ethane-based PE production and reduced naphtha's market share; (ii) China’s pursuit of self-sufficiency, aiming to lead global supply chains and integrate refineries, creating an oversupply in the industry; and (iii) the reconfiguration of refineries, especially in Europe, reducing global naphtha supply which has impacted and may continue to impact the cost of naphtha moving forward. These shocks, combined with slower-growing global demand, have resulted in a surplus of products, especially in China, the United States, and the Middle East, which impacted and continues to significantly impact the margins of the petrochemical industry. In the long-term, the trend is for the down cycle to soften and eventually turn into an upcycle again, as the industry waits to make decisions on new investments while global trade rebalances, and the world demand absorbs new capacity. Additionally, projects that are announced to start up further into the future have a greater chance of being postponed or cancelled, as the scenario may change, feedstocks may become less advantageous, and cash cost curves may shift. Effects of Fluctuations in Naphtha, Ethane, Propane and Propylene Prices Fluctuations in the international market price of naphtha have significant effects on our costs of goods sold and the prices that we are able to charge our customers for our first and second-generation products. Political instability in the Middle East or similar events that may occur, including the military conflict between Russia and Ukraine and, more recently, the conflicts involving Hamas, Israel and Hezbollah, and other conflicts in the Middle East, may lead to unpredictable effects on the global economy or the economies of the affected regions. These events have had and may continue to have negative impacts on oil production and price volatility, consequently driving naphtha and petrochemical prices higher worldwide. The price of ethane and propane in the Mont Belvieu region in Texas and Henry Hub in the United States are used as a reference for our feedstock costs. Any future developments that affect the U.S. supply/demand balance for natural gas may adversely affect the Mont Belvieu and Henry Hub price of natural gas (and thus ethane, propane and butane) and increase our production costs or decrease the price of petrochemical products. External factors and natural events such as hurricanes, harsh winters or industry developments, such as shale gas exploration, may disrupt the supply of natural gas, thereby increasing the cost, which may materially adversely affect our cost of products sold and results of operations. The price of propylene is based on the US reference and is determined by three different processes: (i) refineries production (FCC – Fluidized Catalytic Cracking), steam cracking, and on-purpose production (PDH – Propane Dehydrogenation), since refineries are the major source of propylene in the United States; however, (ii) refineries can use propylene to make a few different products. Their desire to sell propylene on the open market depends on demand and price for gasoline along with a few other chemicals. For the steam cracker process, propylene is a co-product derived from the ethane, propane, and butane cracking processes, whose price dynamics correlate to the price of crude oil; and/or (iii) natural gas, as explained above. Steam cracker feedstock choice has a significant effect on propylene supply to the market since its volume production is different for each feedstock. During the last few years, ethane has been the main feedstock, due to its lower price and to the high polyethylene demand. For the PDH process, propane prices play an important role in propylene pricing, but it mostly sets the price floor, not the ceiling. This is because PDHs are the marginal propylene producer. The price ceiling is determined by the ability to sell propylene products, domestically and internationally. 110 Table of Contents Effects on Cost of Products Sold Naphtha is the principal raw material used by our chemicals operations that are part of our Brazil Segment. Naphtha and condensate accounted for 35% of our consolidated cost of products sold during 2025. The cost of naphtha varies in accordance with international market prices, which fluctuate depending upon the supply and demand for oil and other refined petroleum products. We purchase naphtha under long-term supply contracts with Petrobras, and we import naphtha from other suppliers through our terminal at Aratu, in the State of Bahia and Petrobras’ terminal at Osório, in the State of Rio Grande do Sul. The prices that we pay for naphtha under these arrangements, other than our supply contract with Petrobras, are based on the Amsterdam-Rotterdam-Antwerp (ARA) market price for naphtha. As a result, fluctuations in the ARA market price for naphtha have had a direct impact on the cost of our first-generation products. Our contracts with Petrobras provide for naphtha prices based on ARA quotations. The volatility of the quotation of this product in the international market, the real/U.S. dollar exchange rate, and the level of carbon disulfide, a contaminant of the naphtha that is delivered, also influence the price of naphtha that we purchase from Petrobras. We believe that these contracts have reduced the exposure of the cost of our first-generation products to fluctuations in the ARA market price for naphtha. The international price of naphtha has fluctuated significantly in the past, and we expect that it will continue to do so in the future. Significant increases in the price of naphtha and, consequently, the cost of producing our products, generally reduce our gross margins and our results of operations to the extent that we are unable to pass all of these increased costs on to our customers and may result in reduced sales volumes of our products. Conversely, significant decreases in the price of naphtha and, consequently, the cost of producing our products, generally increase our gross margins and our results of operations and may result in increased sales volumes if this lower cost leads us to lower our prices. In periods of high volatility in the U.S. dollar price of naphtha, there is usually a lag between the time that the U.S. dollar price increases or decreases and the time that we are able to pass on increased, or required to pass on reduced, costs to our customers in Brazil. These pricing discrepancies decrease when the U.S. dollar price of naphtha is less volatile. We do not currently hedge our exposure to changes in the prices of naphtha because a portion of our sales are exports payable in foreign currencies and linked to the international market prices of naphtha and also because the prices of our polyethylene, polypropylene and PVC products sold in Brazil generally reflect changes in the international market prices of these products. The hedge strategy is focused on mitigating short-term price volatility and temporary dislocations that may affect specific purchases not contracted on a monthly average basis through swap transactions. These exposures are converted into a monthly average pricing structure, reducing sensitivity to intramonth price fluctuations and episodic market movements. Effects on Prices of Our Products In Brazil, the prices we charge for many of our chemical products and thermoplastic resins in general are determined by international references linked to the contract prices for these products. Prices for second-generation products exported from Brazil are generally based on international spot market prices. We set the prices for products sold in the United States and Europe based on market pricing in such regions. The price for PE in Mexico is based on prices in the U.S. Gulf Coast region. 111 Table of Contents We negotiate the prices in reais for part of our products, principally polyethylene, polypropylene and PVC, on a monthly basis with our domestic customers. We attempt to revise our prices to reflect (1) changes in the international market prices of these products, which tend to fluctuate in tandem with naphtha prices, especially for polyethylene, and (2) the appreciation or depreciation of the real against the U.S. dollar. However, during periods of high volatility in international market prices or exchange rates, we are sometimes unable to fully reflect these changes in our prices in a prompt manner. The international market prices of our petrochemical products have fluctuated significantly, and we believe that they will continue to do so. Volatility of the price of naphtha and the price of petroleum have effects on the price competitiveness of our naphtha-based crackers and our resins. Because pricing trends for naphtha and ethane have diverged in recent years to a greater extent than has been the case historically, producers of ethylene and resin products derived from ethane generally have experienced lower unit raw material costs than naphtha-based producers of these products. As a consequence, significant increases in the pricing differential between naphtha and gas, as a consequence of higher oil prices, increases the competitiveness of products derived from ethane and may result in an effect on our results of operations to the extent that we are able to maintain our operating margins and increased prices do not reduce pressure in the international markets. Significant increases in the international market prices of our petrochemical products and, consequently, the prices that we are able to charge, generally increase our net revenue and our results of operations due to increased sales volumes of our products. Conversely, significant decreases in the international prices of our petrochemical products, and, consequently, the prices that we charge, generally reduce our net revenue and our results of operations if we are unable to increase our operating margins or these reduced prices do not result in increased sales volumes of our products. Capacity Utilization Our operations are capital-intensive. Accordingly, to obtain lower unit production costs and maintain adequate operating margins, we seek to maintain a high capacity utilization rate at all of our production plants. The table below sets forth capacity utilization rates with respect to the production plants for some of our principal products for the periods presented: Year Ended December 31, 2025 2024 2023 Ethylene Brazil 68% 72% 71% PE Brazil 68% 73% 72% PP Brazil 68% 75% 73% PVC Brazil 60% 65% 70% PP United States and Europe 74% 74% 81% PE Mexico 64% 78% 77% In 2025, the average utilization rate of petrochemical crackers in Brazil decreased compared to 2024, mainly due to (i) the decrease of production levels to meet lower demand during the period; and (ii) a scheduled maintenance shutdown at the Bahia Petrochemical Complex, completed in January 2026. In the United States and Europe segment, the average utilization of PP plants remained consistent with 2023. Compared to 2024, the utilization rate of PE plants in Mexico was lower, mainly due to the scheduled general maintenance shutdown at the Braskem Idesa petrochemical plant during the second and third quarters of 2025. In 2025, the average supply of ethane was approximately 41 thousand barrels per day, lower than the volume supplied in 2024 (50 thousand barrels per day), mainly due to the scheduled maintenance shutdown of the Braskem Idesa petrochemical plant in 2025. The average supply of ethane by Pemex was approximately 17 thousand barrels per day. Braskem Idesa imported an average of approximately 16 thousand barrels of ethane from the United States through the Fast Track Solution. Additionally, in 2025, the ethane import terminal began operating in the third quarter of 2025, with an initial supply capacity of 8 thousand barrels of ethane annually. 112 Table of Contents In 2024, the average utilization rate of petrochemical crackers in Brazil remained in line with 2023, mainly due to the normalization of operations after the scheduled maintenance shutdown at the Bahia Petrochemical Complex in the fourth quarter of 2023, partially offset by the shutdown of operations at the Triunfo Petrochemical Complex, in Rio Grande do Sul, due to the extreme weather event that hit the state in the second quarter of 2024. In the United States and Europe segment, year over year, the utilization rate was lower mainly due to: (i) scheduled maintenance shutdowns at the plants in Europe and at one plant in the United States; and (ii) the unscheduled maintenance shutdown at a plant in the United States during the first quarter of 2024, lasting approximately one month, and the unscheduled maintenance shutdowns at the plants in Europe during the fourth quarter of 2024. Compared to 2023, the utilization rate of PE plants in Mexico was higher, reaching the highest annual utilization rate since 2017 due to the higher availability of ethane. In 2024, the average supply of ethane was approximately 50 thousand barrels per day, higher than the volume supplied in 2023 (49.5 thousand barrels per day). The average supply of ethane by Pemex was approximately 29 thousand barrels per day, below the minimum contractual volume. Braskem Idesa imported an average of approximately 21.1 thousand barrels of ethane from the United States through the Fast Track Solution. In 2023, the average utilization rate of petrochemical crackers in Brazil was impacted by: (i) production adjustments due to weaker global demand for our products; and (ii) the scheduled maintenance shutdown at the petrochemical complex in Bahia. In Mexico, the utilization rate was higher by 4pp compared to 2022, as a result of increased volume of ethane supplied by PEMEX, which reached 32.2 thousand barrels per day on average for the year, representing an increase of 16% compared to 2022. Effects of Brazilian Industrial Policy The Brazilian government has a significant influence in some sectors of the domestic economy, including the petrochemical sector in which we operate. The Brazilian government has adopted, or is considering adopting, measures to boost the competitiveness of domestic companies, as described below. Moreover, the sector is highly regulated in Brazil. SUDENE – Income Tax Reduction Since 2015, Braskem obtained a tax benefit with the effect of reducing 75% of CIT on income from the following industrial units: (i) PVC and chlor-alkali (cloro soda) units, established in the state of Alagoas; and (ii) Chemicals, PE, and PVC, established in the city of Camaçari (BA). It benefits legal entities with projects for the implementation, modernization, or expansion of industrial enterprises. The benefit can be used for a period of ten years. The tax benefit for the units in Camaçari (BA) has been successfully renewed for an additional ten-year period, extending the benefits through 2033. The other units are under a process to renew the tax benefit. In 2025, the operations in Brazil recorded tax losses, therefore the benefit was not available for use. PRODESIN – ICMS Tax Incentive Braskem has ICMS tax incentives in the state of Alagoas, through the state of Alagoas Integrated Development Program, or PRODESIN, valid until December 2026, which aimed at implementing and expanding a plant in that state. This incentive is considered an offsetting entry to sales taxes. In 2025, the amount was R$57.6 million (R$28.3 million in 2024). As PRODESIN is considered an investment subsidy, it was allocated to our tax incentive reserve, pursuant to the Brazilian Corporate Law. 113 Table of Contents REIQ – PIS/COFINS Tax Incentive and PRESIQ In 2013, the Brazilian government approved a PIS and COFINS tax rates on raw material purchases by first and second-generation producers in the chemical industry referred to as REIQ. This measure aimed to restore the competitiveness of the industry, which was weakened by factors related to infrastructure, productivity, feedstock, and energy costs, as well as exchange rate volatility, which contributed to the chemical industry’s trade deficit. According to ABIQUIM (Brazilian Chemical Industry Association), this deficit ended 2025 at approximately US$56.4 billion). Between 2013 and 2015, the REIQ benefit rate was set at 8.25%, and, after after subsequent reductions , it remained at 3.65% for an indefinite period. In 2021, however, the Federal Government revoked the REIQ, without prior notice. Subsequently, demonstrating the importance of the chemical industry to Brazil's socio-economic development, the sector and the Congress ensured that REIQ was reinstated with decreasing rates through the end of 2026. In 2023, the benefit rate was set at 1.46%, and for 2024 and through February 2026 the benefit rate was 0.73%. For the year ended December 31, 2025, the Company fully achieved all the conditions established under the decree recognized R$246.0 million in profit or loss related to this tax benefit. By the end of 2025, the Brazilian Congress, considering the challenging conditions faced by the sector in Brazil and noting that several countries have supported their chemical industries through public policies, approved a bill creating a new incentive program for the sector, called PRESIQ, in light of the expected extinction of the taxes underlying REIQ (PIS and COFINS) in 2026 due to Brazil’s consumption tax reform. PRESIQ consists of a financial credits to the sector totaling R$15,000 million from 2027 through 2031, covering both industrial and investment modalities. Braskem has also secured approval for projects under REIQ (“REIQ Investments”), granting an additional tax incentive of 1.5%, linked to investments aimed at expanding production capacity. We have started reporting these incentives through an ancillary obligation known as DIRBI. Based on data submitted to the Brazilian Federal Revenue Service in 2025, the total net benefit from REIQ Investments amounted to R$583.2 million. Additionally, on March 20, 2026, Complementary Law No. 228 was published, providing for an increase in the REIQ benefit from 0.73% to 5.8%, applicable from March through December 2026 corresponding to PIS/COFINS credits, levied on feedstock for the chemical and petrochemical industries, which may be offset against federal taxes. However, since April 2026, the credit rate has been 5.22%, subject to a 10% reduction as provided for under the applicable legislation, and it should remain until the end of the regime. Reintegra In December 2011, the Brazilian government implemented the “Reintegra” program, to improve the competitiveness of Brazilian manufacturers in the export markets by refunding federal taxes levied on their export sales. As a result of this incentive, exports of third generation products by Brazilian companies have increased. The Reintegra program currently provides a refund rate of 0.1%. However, this regime will be discontinued at the end of 2026 as a result of Brazil’s consumption tax reform. For the year ended December 31, 2025, the Company recognized R$8.4 million in profit or loss related to this tax credit. Import Tariffs at Local Ports Historically, tariffs on imports have been set by the Brazilian federal government. However, in recent years, some Brazilian states have established tax incentives to attract imports to local ports in order to increase revenue and develop the local infrastructure of such ports, mainly through the granting of discounts on the ICMS tax rates that would be due to such states. Industry leaders and labor associations allege that such laws create subsidies for imported products, which would harm the Brazilian market. On January 1, 2013, the legislation came into force that reduces the maximum rate of ICMS to be charged by the states from 12.0% to 4.0% on interstate sales of raw materials and other imported goods or that have a share of imports greater than 40.0%. With limited exceptions, the rate of 4.0% is not applicable to imported goods without a domestic equivalent, to goods produced in accordance with the basic production processes and to operations that send gas imported from abroad to other states. As a result, the current tax incentives offered by some Brazilian states to attract imports of products in the form of a discount on the ICMS tax rates that would otherwise be due have become less attractive. 114 Table of Contents Pricing and Tariffs We set prices for ethylene, the principal first generation petrochemical product that we sell to third-party second-generation producers, by reference to international market prices. See “Item 4. Information on the Company—Brazil Segment—Sales and Marketing of Our Brazil Segment.” Prices paid by second generation producers for imported first generation petrochemical products partly reflect transportation and tariff costs. We establish the prices of ethylene by-products, such as butadiene, by reference to several market factors, including the prices paid by second generation producers for imported products. Prices paid for such imports also reflect transportation and tariff costs. The Brazilian government has used import tariffs to implement economic policies. As a result, import tariffs imposed on petrochemical products have varied in the past and may vary in the future. Until September 2024, the import tax applied to Braskem resins was 12.6%, according to the TEC level. Adjustments of tariffs could lead to increased competition from imports and cause us to lower our domestic prices and impact the demand for our products, which would likely result in lower net revenue and could negatively affect our overall financial performance. Additionally, the products we export to the United States and Europe are subject to tariffs in the amount of 6.5% in each jurisdiction, subject to certain preferences. These tariffs generally balance the level of competition of our products produced locally and any future adjustments to these tariff structures could negatively impact our sales in these jurisdictions. Future trade agreements entered into by Brazil, the Mercosur, the United States or the European Union could also lead to increased competition from imports and lower domestic prices. Imports and exports within the free trade area in South America (Southern Common Market), or Mercosur, which is composed of Argentina, Brazil, Paraguay, and Uruguay, have not been subject to tariffs since December 2001. Imports of suspension PVC from Bolivia, Chile, Colombia, Cuba, Ecuador, Israel, Peru, and Venezuela are not subject to tariffs, due to a number of trade agreements. Imports of suspension PVC from Mexico to reduced tariffs of 80% of MFN, due to trade agreements. Measures applied in 2025 The Executive Management Committee ("Gecex") of the Foreign Trade Chamber ("Camex") approved the temporary increase of the import tax from 12.6% to 20%, by including the following products in the Camex List of Temporary Tariff Increases due to Conjunctural Trade Imbalances: (i) PE Resins: · Polyethylene with a density of less than 0.94, without fillers (NCM 3901.10.10) · Other polyethylene without fillers, density >= 0.94, in primary forms (NCM 3901.20.10) · Other copolymers of ethylene and vinyl acetate, in primary forms (NCM 3901.30.10) · Copolymers of ethylene and alpha-olefin, with a density of less than 0.94 (NCM 3901.40.10) (ii) PP Resins: · PP without fillers, in primary form (NCM 3902.10.20) · Copolymers of propylene, in primary forms (NCM 3902.30.00) 115 Table of Contents (iii) PVC Resin: · PVC, not mixed with other substances, obtained by suspension process (NCM 3904.10.10) · This measure was initially valid from October 15, 2024, to October 14, 2025. In 2025, the sector requested the renewal of the tariff increase, and Gecex approved the extension of the measure until October 2026. Trade Remedies Since the 1990s, imports of suspension PVC from the United States and Mexico have been subject to anti-dumping duties of 16.0% and 18.0%, respectively, that were imposed by the Brazilian Foreign Trade Chamber (Câmara de Comércio Exterior, or “CAMEX”). The duties imposed on imports from the United States and Mexico were revised in 2022 by the Brazilian government, which decided to extend until 2027 the application of anti-dumping duties for imports from the United States with an ad valorem rate reduced to 8.2%, and from Mexico at the rate of 13.6%, but with an immediate suspension of the application of anti-dumping duties for imports from Mexico. In June 2023, the Brazilian Department of Commercial Defense (DECOM) initiated a review of the anti-dumping duty applied to Brazilian imports of suspension PVC originating from the United States due to a change in circumstances that could lead to an increase in the applied antidumping duties. At the end of the investigation, the Brazilian authority concluded that the antidumping measure of 8.2% was not sufficient to neutralize the practice of dumping on PVC imports from the United States and decided to increase the duty to 43.7%, as published in Gecex Resolution No. 737 of May 28, 2025. The measure remains in force until September 19, 2027 Since 2008, imports of suspension PVC from China have also been subject to anti-dumping duties of 21.6%. Such duties had been temporarily suspended in August 2020 but were reinstated in September 2021. In August 2025, the Brazilian government initiated a review of the anti-dumping duty on PVC from China to investigate the likelihood of recurrence of injury and dumping should the measure be terminated. The review was requested by Braskem and is expected to be concluded by August 2026. During the investigation period, the anti-dumping duty of 21.6% remains in effect. Imports of suspension PVC from South Korea were subject to anti-dumping duties ranging between 0% and 18.9%, depending on the producer, between 2008 and August 2020, when they were terminated. Additionally, in December 2010, CAMEX imposed an anti-dumping duty of 10.6% on PP imports from the United States, which was extended in November 2016 and later in October 2022. In this final review, the Brazilian government decided to extend the duties applied on imports of PP from the United States until 2027, but with an immediate suspension of the application of the anti-dumping duties. Later, in February 2024, the Brazilian government decided to reapply the antidumping duties applied on imports of PP from the United States at an ad valorem rate of 10.6%. In August 2014, the Brazilian government also imposed anti-dumping duties on PP imports from South Africa, India and South Korea of 16.0%, 6.4% to 9.9%, and 2.4% to 6.3%, respectively. In December 2020, the Brazilian government extended the anti-dumping duties imposed on PP imports from India, reduced the anti-dumping duties for South Africa to a range from 4.6% to 16% and terminated the duties applied against South Korea. In December 2025, the Brazilian government initiated a review of the anti-dumping duty on PP from South Africa and India to investigate the likelihood of recurrence of injury and dumping should the measure be terminated. The review was requested by Braskem and is expected to be concluded by December 2026. During the investigation period, the anti-dumping duties currently applied remain in effect. In November 2024, the Brazilian Department of Commercial Defense (DECOM) initiated an original investigation to determine the existence of dumping in exports of polyethylene resins from the United States and Canada to Brazil, classified under subheadings 3901.10.30, 3901.20.29, and 3901.40.00 of the MERCOSUR Common Nomenclature (NCM), and the resulting injury to the domestic industry from such practices. The investigation process may last up to 18 months. 116 Table of Contents In August 2025, DECOM published a preliminary determination of the investigation, recommending the application of a provisional anti-dumping duty for six months to contain the injury to the domestic industry during the investigation. Consequently, the provisional antidumping duty was applied starting on August 29, 2025, and will remain in effect for six months. This measure imposes an antidumping duty of US$238.49 per metric ton on imports of polyethylene originating from Canada and US$199.04 per metric ton on imports originating from the United States. Effect of Level of Indebtedness and Interest Rates As of December 31, 2025, our total outstanding consolidated indebtedness (includes borrowings and debentures), was R$66,128 million (US$12,018 million), including R$14,308 million (US$2,600 million) related to Braskem Idesa. The level of our indebtedness results in significant financial expenses that are reflected in our statement of profit or loss. Financial expenses consist of interest expense, exchange variations of U.S. dollar and other foreign currency-denominated debt, foreign exchange losses or gains, and other items as set forth in note 29 to our audited consolidated financial statements. In the year ended December 31, 2025, we recorded total financial expenses of R$6,802 million, mainly associated with: (i) R$4,945 million of interest expenses; (ii) R$861 million related to adjustment to present value – appropriation; and (iii) R$305 million related to interest expenses on leases. In addition, in the year ended December 31, 2025, we recorded a positive result of R$3,474 million in derivatives and exchange rate variations, net in connection with foreign exchange variation on our financial assets and liabilities and results with derivatives. The interest rates that we pay depend on a variety of factors, including prevailing Brazilian and international interest rates and our risk assessments, our industry and the Brazilian economy made by our potential lenders, potential purchasers of our debt securities and the rating agencies that assess us and our debt securities. Effect of Taxes on Our Income We are subject to a variety of generally applicable federal and state taxes in multiple jurisdictions on our operations and results. We are generally subject to Brazilian federal income tax at 25% (including surtax), combined with Social Contribution on Net Income (Contribuição Social Sobre o Lucro Líquido, or “CSLL”) at 9%, totalizing a nominal rate of 34%, which is the standard corporate tax rate in Brazil. We have available certain federal tax exemptions based upon federal law that offers tax incentives to companies that locate their manufacturing operations in the Brazilian states of Bahia. These exemptions represent a 75% reduction of our tax burden, and, as a result, we are entitled to pay 25% of the statutory income tax rate on the profits arising from the sale of polyethylene, basic chemicals and PVC manufactured at one of our plants in the Northeastern Complex (State of Bahia) until 2033. The exemption of 75% of income tax rate combined with CSLL at 9%, entitles us to pay only 44.9% of the 34% standard corporate tax rate on the profits arising from products manufactured at these plants. Income tax loss carryforwards available for offset in Brazil do not expire. However, the annual offset is limited to 30% of our adjusted net taxable basis profit. This limit also affects CSLL. The consolidated amount includes the impact from the different tax rates in countries where foreign subsidiaries are located, which as of December 31, 2025, were as follows: · Braskem Europe (Germany): 31.33% (including surcharges); · Braskem America and Braskem America Finance (United States): 21% + sales tax; · Braskem Argentina (Argentina): 35%; · Braskem Petroquímica Chile (Chile): 27%; · Braskem Netherlands, Braskem Netherlands Finance and Braskem Netherlands Inc. and Other Dutch Companies (The Netherlands): 25.8%; 117 Table of Contents · Braskem Idesa, Braskem Idesa Serviços, Braskem México, Braskem México Serviços and Braskem México Sofom (Mexico): 30%; and · Braskem India (India): 25% (including surcharges). In addition, the introduction of a global minimum tax at a rate of 15% under the Two-Pillar Solution, agreed upon by over 135 jurisdictions under the Organization for Economic Co-operation and Development (OECD)/G20 Inclusive Framework on Base Erosion and Profit Shifting (BEPS), brings an additional tax impact on countries in which the effective tax rate is below 15%. Depending on results per business segments, an additional tax (qualified domestic minimum top-up tax) might be applicable to specific countries and/or there may be a pick-up by the country of Group Ultimate Parent Entity (Income Inclusion Rule). The consolidated amount also includes the impact of taxation on universal bases, which was introduced in Brazil by articles 76 and 77 of Law No. 12,973/2014. This law determines that positive portions of results earned by subsidiaries abroad will be computed in the corporate income tax (Imposto de Renda da Pessoa Jurídica, or “IRPJ”) calculation base and CSLL in Brazil on an individual basis. In case the subsidiary has previous losses, these may be deducted up to the amount of the calculated profit, therefore, the taxpayer is obliged to inform the tax authority of the accumulated losses in the annual corporate income tax return. All profits earned by the subsidiaries described above are subject to IRPJ and CSLL taxation in Brazil, except for profits earned by subsidiaries headquartered in countries with which Brazil has a treaty to avoid double taxation. Profits earned by companies headquartered in those countries will only be taxed when distributed to their respective controlling entities. In addition, the universal basis taxation mechanism also allows the use, as a tax credit, of the tax that was proven to be paid by subsidiaries abroad (including the Pillar Two tax provision paid abroad, as introduced by Law No. 15,079/2024) limited to the tax due on the profit of the subsidiary in Brazil at the rate of 34%. In addition, the legislation also allows that, until 2024, the parent company in Brazil can apply a presumed tax credit at 9.0% on the profit earned by subsidiaries abroad that have industrial activity. Braskem applies this mechanism to its subsidiaries Braskem Europe GmbH, Braskem America Inc. and Braskem Idesa SAPI. Our export sales are currently exempt from (1) PIS – Contribution to the Social Integration Plan, (2) COFINS – Contribution for Social Security Financing, a federal value-added tax, (3) IPI, a federal excise tax on industrialized goods, and (4) ICMS, a state value-added tax on sales and services. In the year ended December 31, 2025, management reassessed the recoverability of the deferred tax assets of the Company and its subsidiaries, in accordance with IAS 12, considering all available evidence, positive and negative, on the existence of future taxable profits sufficient to realize the credits recorded. This process included, among others, the analysis of the recent history of results, the performance projections contained in the approved business plan, the expiration date of tax losses and the applicable tax planning strategies. Thus, in the year ended December 31, 2025, deferred tax assets were written off in the amount of R$11,107 million, with an effect of R$8,759 million on the year’s income and R$2,348 million on comprehensive income Brazil Tax Reform The new regulatory framework for consumption taxation in Brazil aims to simplify the tax system for transactions involving the sale of goods and services, with significant implications for the petrochemical industry. This reform, established by Constitutional Amendment No. 132 at the end of 2023, was followed by the approval of regulatory legislation in late 2024. The federal consumption tax reform is expected to enter a testing phase in 2026 and take full effect in 2027. Meanwhile, the implementation of the state and municipal consumption taxes will follow a gradual transition period from 2029 to 2032. 118 Table of Contents Our management is conducting studies to assess the impacts of this reform and is proactively working to prepare for its implementation. The reform is anticipated to bring indirect benefits to the industry, including a simplified tax system, the ability to claim tax credits on all taxable purchases of goods and services—not just on raw materials—and streamlined internal processes. However, there is an expectation of a gradual reduction in tax incentives as the new framework takes effect, which we are evaluating to fully understand its implications. Statement of Profit or Loss The discussion of the results of our segments is based upon financial information reported for each of the segments of our business, as presented in the following tables, which set forth the results of each of our segments and the reconciliation of these results of our segments to our consolidated results of operations. This segment information was prepared on the same basis as the information that our Chief Operating Decision Maker uses to allocate resources among segments and evaluate their performance. We evaluate and manage the performance of our segments based on information generated from our accounting records maintained in accordance with IFRS Accounting Standards as issued by the International Accounting Standards Board (“IFRS Accounting Standards”). The discussion summarizing the significant factors affecting the results of operations for the year ended December 31, 2025, can be found in Part I, “Item 5. Operating and Financial Review and Prospects” of this annual report.

Year Ended December 31, 2025, Compared with Year Ended December 31, 2024 The following table sets forth our consolidated financial information for the years ended December 31, 2025, and 2024. 119 Table of Contents 2025 2024 % Change (in millions of reais) Net revenue 70,717 77,411 (9%) Cost of products sold (69,161) (71,414) (3%) Gross profit 1,556 5,997 (74%) Income (expenses): Selling and distribution (2,067) (1,991) 4% Reversal of (loss for) impairment of trade accounts receivable and others from clients (125) 108 (216%) General and administrative (2,615) (2,639) (1%) Research and development (460) (463) (0%) Results from equity-accounted investees 9 (21) (143%) Other income 3,213 978 229% Other expenses (1,318) (3,048) (57%) (Loss) before financial results and taxes (1,807) (1,079) 67% Financial results: Financial expenses (6,802) (6,853) (1%) Financial income 2,290 1,719 33% Derivatives and exchange rate variations, net 3,474 (11,520) (130%) Financial results (1,038) (16,654) (94%) (Loss) before income tax (2,845) (17,733) (84%) Income taxes (8,116) 5,681 (243%) Loss profit for the year (10,961) (12,052) (9%) Net revenue Net revenue decreased by R$6,694 million, or 9%, to R$70,717 million in 2025 from R$77,411 million in 2024, attributable mainly to: (i) the decrease of R$3,070 million in net revenue from our Brazil segment is due to the reduction in the average international reference price of resins and main chemicals, with a negative impact of R$973 million; and the reduction in the volume of sales of resins and main chemicals in the Brazilian market and exports, with a negative impact of R$2,235 million; (ii) the decrease of R$3,044 million in net revenue from our United States and Europe Segment; and (iii) the decrease of R$1,045 million in net revenue from our Mexico segment due to the reduction in the average international reference price of PE, with a negative impact of R$423 million; and the reduction in the volume of sales of PE in the year, with a negative impact of R$622 million. Such effects were partially offset by the positive impact on the Brazil segment of the presumed PIS/COFINS credits under the REIQ Investments in the net amount of R$583.2 million. Net Revenue of Brazil Segment Net revenue of our Brazil segment decreased by R$3,070 million, or 6%, to R$51,774 million in 2025 from R$54,844 million in 2024, mainly explained by (i) a 5% reduction or 175 thousand tons in the volume of sales of resins in the Brazili an market; (ii) a 13% reduction in the average international price reference of main chemicals; (iii) a 5% reduction or 128 thousand tons in the sales volume of the main chemicals in the Brazilian market; (iv) a 10% reduction in the average international reference price of resins; and (v) a 27% reduction or 72 thousand tons in the export volume of the main chemicals in the international market. Additionally, in 2025 the revenue of the Brazil segment was positively impacted by around R$583 million of PIS/COFINS credits related to REIQ Investimentos, calculated in accordance with current legislation. 120 Table of Contents The table below sets forth information regarding the weighted average international prices of main chemicals and resins that are generally used as a reference for our Brazil Segment for the periods indicated: International References(1) Year Ended December 31, 2025 2024 % Change (in US$/ton) Main Chemicals(2) 920 1,062 (13)% Resins(3) 879 973 (10)% (1) Source: External consulting (spot price).

Net Revenue of United States and Europe Segment Net revenue of our United States and Europe Segment decreased by R$3,044 million, or 16%, to R$16,400 million in 2025 from R$19,444 million in 2024, mainly as a result of the 17% and 7% reduction in international PP price references in the United States and Europe, respectively. The table below sets forth information regarding the weighted average international price of PP, which is generally used as a reference for our United States and Europe Segment for the periods indicated: International References(1) Year Ended December 31, 2025 2024 % Change (in US$/ton) PP United States and Europe(2) 1,461 1,503 (3)% (1) Source: External consulting (spot price).

Net Revenue of Mexico Segment Net revenue of our Mexico segment decreased by R$1,045 million, or 20%, to R$4,103 million in 2025 from R$5,148 million in 2024, as a result of: (i) a reduction of 138 thousand tons, or 16%, in PE sales volume in the year; and (ii) a 12% reduction in the international PE price reference in the international market. International References(1) Year Ended December 31, 2025 2024 % Change (in US$/ton) PE US 908 1,035 (12)% (1) Source: External consulting (spot price). Cost of Products Sold and Gross Profit Cost of products sold decreased by R$2,253 million, or 3%, to R$69,161 million in 2025 from R$71,414 million in 2024, primarily as a result of: (i) a reduction of R$1,949 million in the cost of products sold in the Brazil segment; and (ii) a reduction of R$1,747 million in the cost of products sold in the United States and Europe segment. These effects were partially offset by an increase of R$1,699 million in the cost of products sold in Mexico, mainly due to the recording of impairment loss of approximately R$1,468 million, after the identification that Braskem Idesa’s recoverable amounts of assets were lower than the respective book values. During 2025, cost of products sold was positively impacted by PIS/COFINS credits on the purchase of feedstock (REIQ) by approximately R$246 million (US$44 million) and by Reintegra credits by R$8.4 million (US$1.5 million) 121 Table of Contents Consolidated gross profit decreased by R$4,441 million, or 74%, to R$1,556 million in 2025 from R$5,997 million in 2024. Gross margin (gross profit as a percentage of net revenue) decreased to 2% in 2025 from 8% in 2024. Cost of Products Sold of the Brazil Segment Cost of products sold of our Brazil segment decreased by R$1,949 million, or 4%, to R$48,651 million in 2025 from R$50,600 million in 2024. The reduction is mainly explained by the reduction of (i) 14% and 4% in the international references of naphtha and propane, respectively; (ii) 5% or 175 thousand tons in the volume of resin sales in the Brazilian market; and (iii) 5% or 128 thousand tons in the sales volume of main chemicals in the Brazilian market. These effects were partially offset by an impairment loss of the chlor alkali plant in Alagoas, which aims to make PVC production more competitive and sustainable, of R$546 million. Additionally, during 2025, cost of products sold was positively impacted by PIS/COFINS credits on the purchase of feedstock (REIQ) by R$246 million (US$44 million) and by Reintegra credits by R$8.4 million (US$1.5 million).

Gross profit of our Brazil segment decreased by R$1,121 million, or 26%, to R$3,123 million in 2025 from R$4,244 million in 2024, primarily as result of the decrease in the net revenue due to (i) a decrease in the sales volume of resins; (ii) a decrease in the average international reference price of main chemicals; and (iii) a reduction, in the sales volume of main chemicals. Gross margin (gross profit as a percentage of net revenue) of our Brazil segment decreased to 6% in 2025, from 8% in 2024.

Gross profit of our United States and Europe Segment decreased by R$1,297 million, or 91%, to R$121 million in 2025 from R$1,418 million in 2024 primarily as a result of the decrease in the net revenue due to the decrease in the international PP price average reference of the United States and Europe. Cost of Products Sold by Mexico Segment Cost of products sold of our Mexico segment increased by R$1,699 million, or 38%, to R$6,200 million in 2025 from R$4,501 million in 2024, primarily as a result of the recording of impairment loss in the amount of R$1,468 million, after the identification that Braskem Idesa's recoverable amounts of assets were lower than the respective book values. 122 Table of Contents International References(1) Year Ended December 31, 2025 2024 % Change (in US$/ton) Ethane U.S. 188 141 33% (1) Source: External consulting (spot price). Gross profit of our Mexico segment decreased by R$2,744 million, to a negative value of R$2,097 million in 2025, from R$647 million in 2024, mainly due to the decrease in the net revenue, as a result of the reduction of the volume of PE sales. Selling and Distribution Expenses Selling and distribution expenses increased by R$76 million, or 4%, to R$2,067 million in 2025 from R$1,991 million in 2024, mainly due to (i) the increase in logistics expenses and expenses with storage and tanking services, due to the scheduled shutdown of Braskem Idesa's petrochemical plant; and (ii) the depreciation of the average real against the average dollar of 4% in the period. Reversal of (loss for) for Impairment of Trade Accounts Receivable and Others from Clients Loss for impairment of trade accounts receivable and others from clients totaled R$125 million in 2025, from a reversal of R$108 million in 2024, mainly explained by the increase in provisions for losses in accounts receivable during 2025. General and Administrative Expenses General and administrative expenses decreased R$24 million, or 1%, to R$2,615 million in 2025 from R$2,639 million in 2024, mainly from the lower administrative expenses associated with Cetrel S.A., which was sold in September 2024. These effects were partially offset by the depreciation of the average real against the average dollar of 4% in the period. General and administrative expenses represented 3.7% of net revenue in 2025, compared to 3.4% in the corresponding period of 2024. Research and Development Expenses Research and development expenses decreased by R$3 million, or 1%, compared to 2024, totaling R$460 million in 2025, from R$463 million in 2024, mainly due to the decision to discontinue new investments in Oxygea. This decision is in line with the Company's strategic direction of prioritizing its assets and investments, both operational and strategic, in the search for optimizing capital allocation and cash generation. Results from Equity-Accounted Investees Results from equity investments increased by R$30 million, or 143%, to R$9 million in 2025 from a expense of R$21 million in 2024, mainly due to the higher net income recorded by the associates Borealis Brasil S.A. and Plaind Investimentos S.A. (Holding company created and maintained to manage the control of Cetrel and DAC). This effect was partially offset by the higher loss of Bioglycols LLC. Other Income Other income increased by R$2,235 million, to R$3,213 million in 2025, from R$978 million in 2024, mainly explained by (i) the recognition in 2025 of a tax credit of approximately R$1,670 million related to the deduction of Cide-Combustíveis paid from PIS/COFINS due on the sale of gasoline since 2004; (ii) the recognition in 2025 of PIS and COFINS credits related to the REIQ in the purchase of inputs in the amount of R$465 million, calculated in accordance with current legislation, which are subject to offsetting with federal taxes, subject to the legal terms and conditions; and (iii) the recognition of remaining PIS and COFINS credits from previous years related to the exclusion of ICMS from the calculation basis of these contributions in the amount of R$293 million in 2025. 123 Table of Contents Other Expenses Other expenses decreased R$1,730 million, or 57%, to R$1,318 million in 2025, from R$3,048 million in 2024, mainly explained by (i) the reduction of R$1,799 million in provisions related to the geological event in Alagoas to R$324 million in 2025, from R$1,223 million in 2024; and (ii) the reduction of R$172 million regarding the annual review of the net environmental provisions of the industrial units located in Brazil to R$131 million in 2025, from R$307 million in 2024. (Loss) Before Net Financial Expenses and Taxes As a result of the foregoing, the loss before net financial expenses and taxes on a consolidated basis increased by R$728 million, or 68%, to R$1,807 million in 2025 from R$1,079 million in 2024. The result is mainly explained by the lower result of (i) the United States and Europe segments, which decreased R$1,260 million to a loss of R$718 million in 2025, compared to a profit of R$542 million in 2024, due to the reduction of international propylene price references; and (ii) the Mexico segment, which decreased R$2,521 million to a loss of R$2,391 million in 2025, from a profit of R$130 million in 2024, due to the 16% reduction in PE sales volume in the year added to a 12% reduction in the international PE price reference of the United States in the period. These effects were partially offset by the result of the Brazil segment, which increased by R$2,513 million, million to R$2,632 million from R$119, mainly due to (i) the 7% increase in resin exports; and (ii) the positive impact of the recognition of presumed PIS/COFINS credits within the scope of REIQ Investments Operating margin, defined as a percentage of profit (loss) before net financial expenses and taxes divided by net revenue decreased to negative 3% from negative 1% in 2024, mainly due to lower net revenue in 2025. Financial Results Financial Expenses Financial expenses decreased by R$51 million, or 1%, to R$6,802 million in 2025 from R$6,853 million in 2024 is mainly explained by lower interest expenses related to Braskem Idesa's Shareholder Loan, after its capitalization in 2024. The effect was partially offset by (i) the increase in financial expenses related to tax regularization for the settlement and installment of ICMS debts, and (ii) the depreciation of the average Brazilian real against the U.S. dollar, of about 3.7%. Financial Income Financial income increased by R$571 million, or 33%, to R$2,290 million in 2025, compared to R$1,719 million in 2024, mainly due to: (i) monetary adjustments related to the recovery of PIS/COFINS tax credits, associated with the deduction of CIDE-Fuels on gasoline sales, amounting to approximately R$890 million; and (ii) interest income of approximately R$132 million, related to the recovery of presumed PIS/COFINS credits under the Industrial REIQ program, resulting from the abrupt suspension of the benefit in July 2022, in violation of the Brazilian National Tax Code. Derivatives and Exchange Rate Variations, Net Derivatives and exchange rate variations, net increased by R$14,994 million to an income of R$3,474 million in 2025 from an expense of R$11,520 million in 2024, mainly due to the effects of (i) appreciation of about 11.1% of the final real of the period against the dollar on the annual average of net exposure to the dollar in the amount of US$4,102 million; and (ii) appreciation of around 11.4% of the Mexican peso at the end of the period against the dollar over the average annual exposure to the dollar of Braskem Idesa in the amount of US$1,860 million. 124 Table of Contents Income Tax Income tax was negative by R$8,116 million in 2025 compared to a benefit of R$5,681 million in 2024, mainly explained by (i) the revaluation of the recoverability of the deferred tax assets of the Company and its subsidiaries with a negative effect of R$8,759 million; and (ii) the reduction of R$5,062 million in income taxes calculated by the nominal tax rate of 34% in the year in the year, mainly due to the lower loss before income tax and social contribution impacted by the increase of R$14,994 million in income from derivatives and exchange rate variations. For more information, see note 20 to our audited consolidated financial statements included elsewhere in this annual report. Loss For the Year As a result of the above, we recorded a loss of R$10,961 million in 2025, compared to a loss of R$12,052 million in 2024, mainly due to (i) the reduction of R$4,441 million in gross profit in the period, from R$5,997 million in 2024 to R$1,556 million in 2025; and (ii) the write-off of deferred tax assets with a net impact on the result of R$8,759 million, resulting from factors that indicate potential unavailability of future taxable profits, mainly as a result of current uncertainties in the sector, according to IAS 12. Such effects were partially offset by the increase of R$14,994 million in net gain from derivatives and exchange rate variations, which reached R$3,474 million in 2025, compared to a loss of R$11,520 million in 2024 Liquidity and Capital Resources Our principal cash requirements for 2025 consisted of the following: · servicing and repayment of our indebtedness; · capital expenditures, maintenance, and construction; · payments related to the geological event in Alagoas; and · working capital requirements. Our principal sources of liquidity have traditionally consisted of the following: · cash flows from operating activities; · current and non-current borrowings; · issuance of debt; · credit facilities with banks; · assignment of trade receivables from our sales to funds and financial institutions; and · working capital management mainly through optimization of our cash conversion cycle. As of December 31, 2025, our consolidated cash and cash equivalents and financial investments amounted to R$11,837 million and included R$233 million held by Braskem Idesa, which was restricted to its exclusive use, and R$138 million of restricted funds related to Alagoas and R$384 million regarding reserve accounts. As of December 31, 2025, we had a negative net working capital (defined as current assets minus current liabilities) of R$9,770 million. 125 Table of Contents As of December 31, 2025, our R$5,502 million (US$1,000 million) revolving credit facility was fully withdrawn. Projected Sources and Uses of Cash – Economic and Financial Condition of our Company and Substantial Doubt to Its Going Concern The consolidated financial statements included in this Annual Report have been prepared on a going concern basis of accounting, which contemplates continuity of operations, realization of assets and satisfaction of liabilities and commitments in the normal course of business. However, the notes to our consolidated financial statements refer to a substantial doubt about our ability to continue as a going concern. Considering our current financial contractual obligations and commitments as of December 31, 2025, and budgeted capital expenditures for 2026, we expected that we will be required to spend R$25,937 million (US$4,714 million) during 2026 mainly for (i) our operations, and (ii) our debt service of our existing current indebtedness as it becomes due. As of December 31, 2025, the consolidated statement of financial position presents net working capital (defined as total current assets less total current liabilities), amounting to negative R$9,770 milllion (positive R$8,765 million in 2024). The balances are negative due to the effects of Braskem Idesa’s financings, which were reclassified to current liabilities. Shareholders’ equity is negative by R$16,502 million (R$4,278 million in 2024), mainly impacted in the year by the valuation allowance for realization of deferred tax assets in the amount of R$11,107 million, as disclosed in note 20.2.c to our audited financial statements. The Company comprehensively evaluated the internal and external factors capable of potentially impacting the going concern assumption. Based on the information available and the projections of the approved business plan, we identified a high level of cash usage over the analyzed horizon, considering both the existing cash balances and the projected inflows from the operating cycle. Key elements considered include: · The prolonged downturn cycle in the petrochemical industry, with structurally compressed spreads; · Cash consumption associated with debt service, particularly recurring interest payments; · Cash requirements related to the obligations arising from the Geological Event in Alagoas; · Cash needs for the maintenance of operating assets, essential for ensuring operational continuity and safety; · Credit rating downgrade; and · Maturity of the US$1,000 million stand-by facility in December 2026, requiring a significant cash outflow, if not renewed. These factors, as reflected in the approved business plan, indicate increasing pressure on liquidity and guide management’s actions aimed at continuously adjusting the Company’s financial position to the current challenges faced by the global chemical industry. Among the initiatives currently under development, the planned restructuring of our capital structure is noteworthy, as it depends on variables outside the Company’s exclusive control. The assessment of capital structure restructuring began in 2025 and in September 2025 the Company disclosed to the market the engagement of specialized financial and legal advisors to support a comprehensive diagnosis of the available economic-financial options, with a focus on strengthening liquidity in the capital structure. In the course of this assessment, the Company, with assistance of its advisors, is evaluating a range of strategic and financial alternatives, which may include, among others, potential measures for the protection of the Company against creditors. As of the date of this Annual Report, no decision has been made regarding which alternative, or combination of alternatives, may ultimately be implemented, and there can be no assurance as to the timing, feasibility or outcome of this process. See “Item 3 – Risk Factors – Our financial statements as of and for the year ended December 31, 2025 contain a going concern emphasis, due to increasing pressure on liquidity.” Cash Flows The following table sets forth certain consolidated cash flow information for the periods indicated: 2025 2024 (in millions of reais) Net cash generated from (used in) operating activities (4,200) 2,435 Net cash (used in) investing activities (2,947) (3,485) Net cash generated from financing activities 3,175 469 Exchange variation on cash of foreign subsidiaries (513) 1,380 Increase (decrease) in cash and cash equivalents (4,485) 799 Net Cash Generated from (Used in) Operating Activities Net cash used in operating activities was R$4,200 million during 2025, and net cash generated from operating activities was R$2,435 million during 2024 mainly as a result of the change in working capital during the period explained by: · the reduction of R$2,711 million in financial investments, from R$3,325 million in 2024 to R$614 million in 2025; · the negative change of (i) R$2,727 million in trade payables, from a positive amount of R$384 million in 2024 to a negative amount of R$2,343 million in 2025; and (ii) R$240 million in accounts receivable. These reductions are mainly explained by the reduced availability of certain payment agreements with financial institutions and suppliers. These effects were partially offset by the optimization of inventory levels and tax monetization during the year, initiatives included in the Company's Resilience Program; and · the variation of R$542 million related to the increase in payments and reclassifications related to the geological event of Alagoas, to R$2,594 million in 2025, from R$2,052 million in 2024. Of the amount at the end of 2025, R$1,348 million refer to payments made and R$1,246 million refer to reclassifications to the other obligations group, which totaled a balance of R$1,416 million referring to accounts payable of the geological event in Alagoas. Net Cash (Used in) Investing Activities Net cash used in investing activities was R$2,947 million during 2025, and R$3,485 million during 2024 During 2025, investing activities for which we used cash on consolidated basis primarily consisted of: (i) acquisitions of property, plant and equipment and intangible assets of R$2,554, in the Brazil segment, which were allocated primarily to industrial operations, including the investments related to scheduled maintenance, operating efficiency, health, environmental and safety (HES), including reliability and operating safety of industrial assets, and strategic projects such as the increase of the ethane-based capacity in Rio under the Transforma Rio project, the acquisition of land adjacent to the Duque de Caxias plant, in Rio de Janeiro, and projects in technology for efficiency in the resin chain and in the adaptation of the process for the industrial production of new copolymer grades; (ii) acquisitions of property, plant and equipment and intangible assets of R$215 million in the United States and Europe Segment, which were allocated both to industrial operations and strategic projects; and (iii) acquisitions of property, plant and equipment and intangible assets of R$986 million in the Mexico segment, which were primarily allocated to the scheduled shutdown for general maintenance in Braskem Idesa’s petrochemical complex, asset reliability and integrity initiatives, health, environment, and safety projects (HES), and for the construction of the new ethane import terminal by Terminal Química Puerto México (TQPM). 126 Table of Contents During 2024, investing activities for which we used cash on a consolidated basis primarily consisted of: (i) acquisitions of property, plant and equipment and intangible assets of R$1,815 million, in the Brazil segment, which were allocated primarily to industrial operations, including the investments related to scheduled maintenance, operating efficiency, health, environmental and safety (HES), including reliability and operating safety of industrial assets, productivity, modernization and strategic projects such as the completion of payments for the capacity expansion project of the green ethylene plant in Brazil; (ii) acquisitions of property, plant and equipment and intangible assets of R$242 million in the United States and Europe Segment, which were allocated both to industrial operations and strategic projects; and (iii) acquisitions of property, plant and equipment and intangible assets of R$1,511 million in the Mexico segment, mainly represented by the new ethane terminal. Net Cash Generated from (Used in) Financing Activities Net cash generated from financing activities was R$3,175 million in 2025, as compared to net cash generated from financing activities of R$469 million in 2024 . During 2025, we raised mainly: · R$5,502 million (US$1,000 million) by drwaing all the available amounts under the revolving credit facility; · R$545 million (US$95 million) related to Braskem Idesa’s term loan financing agreement with Banco Inbursa; and · R$188 million (US$34 million) in a credit line contracted with Banco Inbursa, which total available limit is R$468 million (US$85 million) During 2025, we mainly used cash to pay: · R$550 million (US$100 million) through in advanced payments of credit facilities with banks. During 2024, we raised mainly: · R$5,263 million (US$850 million) through the issuance of 8.000% Senior Notes due 2034 in the international capital markets; · R$1,276 million (US$206 million) related to withdrawn of TQPM of the financing amount obtained to build the ethane import terminal in the total amount of R$1,975 million (US$408 million); and 127 Table of Contents · R$619 million (US$100 million) through credit facilities with banks. During 2024, we mainly used cash to pay: · R$2,285 million (US$369 million), relating to the repurchase of part of the outstanding amount of the 8.500% Subordinated Resettable Fixed Rate Notes due 2081; · R$1,548 million (US$250 million) relating to export credit facilities; · R$1,004 million, relating to the payment of aggregate expenses related to lease agreements; and · R$750 million relating to the redemption of our CDI + 1.75% Debenture notes due 2029. Unless our board of directors deems it inconsistent with our financial position and the decision of our board of directors is ratified by our shareholders, payment of minimum dividends is mandatory under Brazilian Corporate Law and our by-laws and also is required under agreements with two of our shareholders and, consequently, may give rise to significant cash requirements in future periods. For additional information, see “Item 8. Financial Information—Dividends and Dividend Policy—Mandatory Distributions.” Contractual Commitments The following table summarizes significant contractual obligations and commitments as of December 31, 2025, which have an impact on our liquidity. We have adopted a calculation methodology to determine minimum cash needs for a 30-day timeframe (the “monthly vision”) and minimum cash needs for a 12-month timeframe (the “yearly vision”) for the purpose, respectively, of: (i) monitoring the liquidity needed to meet obligations coming due in the following month; and (ii) monitoring that we maintain liquidity during potential crises. Minimum cash needed for our “yearly vision” is calculated mainly based on the projected operating cash generation, less current debts and working capital needs. Minimum cash needed for our “monthly vision” considers the projected operating cash disbursements, debt service and contributions to projects, as well as the planned disbursement for derivatives maturing in the following month, among other items. For our financial policy, we adopt the greater of these two references to determine the amount of minimum cash needed. In line with our commitment to maintaining our financial liquidity, in December 2021 we renewed the revolving credit facility in the amount of R$5.5 billion (US$1 billion), which expires in 2026. This credit line may be used without restrictions to improve our credit liquidity or in the event of deterioration in the macroeconomic scenario. The Company drew the full principal amount available as “stand-by” under the revolving credit facility, and R$5.5 billion (US$1 billion) was added to the Company’s cash position on October 3, 2025. The Company’s financial liabilities, by maturity, are shown in the table below. These amounts are calculated based on cash flows not discounted and may not be reconciled with the amounts disclosed in the Consolidated statement of financial position. 128 Table of Contents Within one year Between one and two years Between two and five years More than five years Total (in millions of reais) Trade payables 13,350 21 - - 13,371 Borrowings and debentures 13,677 2,876 26,295 32,989 75,837 Braskem Idesa borrowings 972 187 11,495 10,416 23,070 Derivatives 357 162 370 77 965 Loan from non-controlling shareholder of Braskem Idesa - - - 1,795 1,795 Leniency agreement 72 296 647 - 1,015 Lease 1,103 897 1,593 2,001 5,594 At December 31. 2025 29,531 4,439 40,400 47,278 121,647 Interest discounted to present value (6,159) (1,725) (13,166) (14,582) (35,632) Carrying amount 23,372 2,714 27,234 32,695 86,014 In November 2025, Braskem Idesa defaulted on interest payments related to the bond maturing in 2029. As a result of this non payment, the full outstanding balance of interest and principal of the bond may be accelerated by the bondholders, subject to the applicable contractual quorum. Since the decision to accelerate the debt is not under Braskem Idesa’s control and it does not have the ability to defer these payments for at least 12 months after the reporting date, the balance of this obligation was reclassified to current liabilities, as well as other borrowings that contain cross default clauses in their contracts. The Company’s financial liabilities by maturity date shown in the table below consider the balance of Braskem Idesa’s debt reclassified to current liabilities for financial reporting purposes. As of the date hereof, the Braskem Idesa’s group of bondholders has not required the early payment of this debt.

Revolving Credit Facility Agreement On December 20, 2021, we entered into a revolving credit facility with a syndicate of global lenders in an aggregate amount of up to US$1,000 million, maturing in December 2026. As of December 31, 2025, the entire amount available under the facility had been drawn, as disclosed in a material fact noticed on October 3, 2025. Indebtedness of Braskem Idesa As of December 31, 2025, the carrying amount of the borrowings relating to our Mexico segment was R$14,639 million (US$2,660 million). The Braskem Idesa financing agreements and bond issuance include certain covenants that require, among other things, the presentation of audited financial statements within a certain timeframe. 132 Table of Contents On December 2012, Braskem Idesa entered into a common terms agreement with certain financial institutions to finance the development, design, construction and initial operation of the Mexico Complex. The Mexico Complex includes an ethane cracker with annual capacity of 1.05 million tons to produce ethylene, two high density polyethylene plants and a low-density polyethylene plant. In connection with the common terms agreement, Braskem Idesa entered into eight separate financing agreements with international and Brazilian financial institutions and development banks in an aggregate principal amount of up to R$15 billion (US$3.2 billion), or the Braskem Idesa Financing. All amounts disbursed under these credit facilities were secured by our shares in Braskem Idesa. In September 2015, Braskem Idesa received the final disbursement pursuant to the common terms agreement, reaching an aggregate principal amount of R$14 billion (US$3 billion). On November 25, 2019, Braskem Idesa issued R$4,954 million (US$900 million) in aggregate principal amount of 7.450% senior secured notes due 2029. The 2029 notes are senior secured obligations of Braskem Idesa and rank pari passu with the existing Braskem Idesa senior secured obligations due 2032 and the credit facility. Interest on the notes is payable semi-annually, and the principal amount becomes due at maturity. The proceeds of the notes were used to partially refinance Braskem Idesa’s existing secured project finance indebtedness incurred in 2012 to construct a Complex in Mexico. Excess proceeds of the issuance were used to prepay certain other indebtedness of Braskem Idesa. On October 11, 2021, Braskem Idesa entered into a senior secured syndicated term loan facility of up to R$3,338 million (US$600 million) with Morgan Stanley Senior Funding, Inc., Credit Agricole Corporate and Investment Bank, Deutsche Bank AG, London Branch and Itaú Unibanco S.A., Miami Branch, as lenders. The credit facility is secured by first priority security interest in favor of the lenders and all lenders share the collateral equally with the holders of the 2029 and 2032 notes and potential additional secured parties as permitted under the credit facility and the indenture governing the notes. The credit facility has a five-year term and will bear interest at a rate equal to quarterly Term SOFR plus an applicable margin ranging from 2.25% to 4.25% (depending on Braskem Idesa credit rating), to be paid quarterly. The principal amount will be repaid in semi-annual installments commencing 24 months after the closing date. The loan under the credit facility was partially drawn, R$837 million (US$150 million) on October 20, 2021 in order to fully prepaid the project finance indebtedness incurred in 2012, along with the 2032 notes issued by Braskem Idesa. On October 20, 2021, Braskem Idesa issued R$6,606 million (US$1,200 million) in aggregate principal amount of 6.990% senior secured sustainability linked notes due 2032. The notes are senior secured obligations of Braskem Idesa and rank pari passu with the existing Braskem Idesa senior secured notes due 2029 and the credit facility. Interest on the notes is payable semi-annually, and the principal amount becomes due at maturity. The 2032 notes accrue an interest step-up by 37.5 basis points to 7.365% per annum if Braskem Idesa does not satisfy the sustainability performance target to reduce absolute GHG emissions by 15% from a 2017 baseline by year-end 2028. The proceeds of the notes were used (jointly with the credit facility) to fully refinance Braskem Idesa’s existing secured project finance indebtedness incurred in 2012 to construct a Complex in Mexico. With this financing, Braskem Idesa concluded its debt refinancing plan, replacing the remaining balance of US$1,350 million from its project finance facility with new debt instruments with a longer maturity, which extended its average debt maturity term from five to nine years. With the repayment of the project finance facility, the financial guarantees granted by Braskem for the benefit of Braskem Idesa, in the total amount of US$358 million, were extinguished. In October 2024, Braskem Idesa’s shareholders, Braskem and Grupo Idesa, approved a capital increase through the capitalization of the principal amount of the existing shareholder loan, totaling approximately R$8.8 billion (US$1.6 billion). This transaction aimed to strengthen Braskem Idesa’s capital structure by reducing its financial liabilities and reinforcing shareholder commitment to the project. The capital increase maintained the pre-existing ownership structure between the shareholders. The accrued interest on the shareholder loan, amounting to approximately R$3.5 billion (US$561 million), remains outstanding and is expected to be repaid by March 31, 2032. 133 Table of Contents On October 22, 2025, Braskem Idesa upsized its term loan facility from R$523 million (US$95 million) to R$990 million (US$180 million). Disbursements of new loans under the upsized term loan facility accrue interest at 4.50% and mature on December 31, 2026. On September 2025, Braskem Idesa retained legal and financial advisors to support the evaluation of a wide range of economic-financial options to review its existing capital structure and liquidity conditions On November 18, 2025, Braskem Idesa, a subsidiary of Braskem S.A., missed a scheduled interest payment in the amount of R$184.5 million (US$33.5 million) on its 7.450% Senior Secured Notes due 2029 with a total outstanding principal amount of R$4,952 million (US$900 million). On February 20, 2026, Braskem Idesa missed a scheduled interest payment in the amount of R$230.8 million (US$41.9 million) on its 6.990% Senior Secured Notes due 2032 with a total outstanding principal amount of US$1,200,000,000.

Braskem Idesa pledged as guarantee property, plant and equipment assets in the same value as the bond. (4) Terminal Química pledged as collateral property, plant and equipment assets. Capital Expenditures During 2025, investing activities for which we used cash on consolidated basis primarily consisted of: (i) acquisitions of property, plant and equipment and intangible assets of R$2,554, in the Brazil segment, which were allocated primarily to industrial operations, including the investments related to scheduled maintenance, operating efficiency, health, environmental and safety (HES), including reliability and operating safety of industrial assets, and strategic projects such as the increase of the ethane-based capacity in Rio under the Transforma Rio project, the acquisition of land adjacent to the Duque de Caxias plant, in Rio de Janeiro, and projects in technology for efficiency in the resin chain and in the adaptation of the process for the industrial production of new copolymer grades; (ii) acquisitions of property, plant and equipment and intangible assets of R$215 million in the United States and Europe Segment, which were allocated both to industrial operations and strategic projects; and (iii) acquisitions of property, plant and equipment and intangible assets of R$986 million in the Mexico segment, which were primarily allocated to the scheduled shutdown for general maintenance in Braskem Idesa’s petrochemical complex, asset reliability and integrity initiatives, health, environment, and safety projects (HES), and for the construction of the new ethane import terminal by Terminal Química Puerto México (TQPM). For additional information, see “Item 5. Operating and Financial Review and Prospects—Capital Expenditures” in our Annual Report. 134 Table of Contents Capital Expenditure Budget We plan to invest R$2,565 million (US$465 million) in 2026, approximately 25% less than the historical average of the last six years (US$627 million), prioritizing investments in maintenance, operational and process safety, and asset mechanical integrity. · Operating investments: (i) scheduled maintenance stoppages at the Rio Grande do Sul petrochemical plant and other resin plants in Brazil; (ii) regulatory investments and those related to operational and process safety; and (iii) asset mechanical integrity program and spare parts acquisition for operational continuity; and · Strategic investments: (i) investments in technological developments; and (ii) acquisition of industrial land in the Duque de Caxias industrial hub in Rio de Janeiro. With respect to Braskem Idesa, investments of R$234 million (US$42 million) are planned in 2026, directed towards operational investments in the maintenance and operation of the petrochemical complex and toward projects related to operational efficiency, such as maintenance, productivity, and HES. Joint Ventures Related to Our Mexico Segment Mexico Complex Braskem and Idesa formed Braskem Idesa in April 2010 to develop, construct and operate the Mexico Complex, located in the Mexican state of Veracruz. The Mexico Complex includes an ethylene cracker that produces 1.05 million tons of ethylene per year from ethane based on technology licensed from Technip Italy S.p.A., or Technip, two high density polyethylene plants based on Innovene S technology licensed from Ineos Commercial Services UK Limited (as successor to Ineos Europe Limited) and a low-density polyethylene plant based on Lupotech T technology licensed from Basell Polyolefin GmbH. The three polyethylene plants have a combined annual production capacity of 1.0 million tons of HDPE and LDPE. Braskem Idesa is a party to an ethane supply agreement with Pemex, a subsidiary of Pemex, dated February 19, 2010 (“BI’s Ethane Supply Agreement”). As per the terms and conditions provided in BI’s Ethane Supply Agreement, ethane supply is assured through a 20-year contract with Pemex at a price pegged to the U.S. gas price. On September 27, 2021, Braskem Idesa signed the following documents: (i) Amended ESA with PEMEX, with settlement of any pending contractual amounts; and (ii) Terminal Agreement. The Amended ESA modified the minimum contractual volume commitment to 30,000 barrels/day until February 2025 (subject to extensions in the event of delay in obtaining the licenses for the terminal’s construction). Pemex and Braskem Idesa have agreed to extend the contractual volume until February 2026 or until the ethane import terminal is constructed, commissioned and commercially operational. As of February 9, 2026, the contractual volume commitment under the Amended ESA expired, and the parties entered into a right of first refusal arrangement in favor of Braskem Idesa, without any minimum volume obligation The Amended ESA further establishes first-refusal rights, which consists of a preemptive right for Braskem Idesa in the acquisition of all ethane that PEMEX has available and does not consume in its own production process through 2045, at prices based on international references. The terminal project is designed to supplement ethane supply in Mexico by gaining access to new feedstock sources. In February 2010, we and Idesa entered into the Braskem Idesa shareholders’ agreement to govern our relationship with respect to Braskem Idesa, which was amended in November 2012, December 2012, April 2015, April 2017 and October 2021. The Braskem Idesa shareholders’ agreement, as amended, sets forth the understanding of the parties regarding the implementation of this project and the relationship of Braskem and Idesa as shareholders of Braskem Idesa. Under the Braskem Idesa shareholders’ agreement, as amended: 135 Table of Contents · the parties agree to use their best efforts to use Braskem Idesa as their commercialization vehicle for polyethylene in Mexico; · the parties agree that the polyethylene production of Braskem Idesa shall be strategically focused on supplying the Mexican market; · we have the right to appoint five members and Idesa has the right to appoint two members of Braskem Idesa’s board of directors; decisions considered at Braskem Idesa’s general shareholders’ meetings require the approval of at least 50% plus one of the voting shares of Braskem Idesa. Decisions considered by Braskem Idesa’s board of directors require the approval by a simple majority of votes of its members; · upon the failure of Braskem and Idesa to agree to vote in favor of certain matters requiring a supermajority vote in an extraordinary shareholders’ meeting, (1) we will have the right to seek approval of such matters by a simple majority vote of Braskem Idesa’s shareholders, (2) in the event that such matters are approved by a simple majority vote of Braskem Idesa’s shareholders, we will have the option to purchase all of the shares then held by Idesa, and (3) in the event that we do not exercise this right, Idesa will have the option to sell all of its shares of Braskem Idesa to us; and · any disputes between Braskem and Idesa arising out of or in connection with the Braskem Idesa shareholders’ agreement will be resolved through arbitration. The Braskem Idesa shareholders’ agreement also contains rights of first refusal, tag along rights and drag along rights in connection with the disposition of Braskem Idesa shares. Construction of the Mexico Complex began in 2012, and it commenced operations with the production of the first batch of polyethylene in April 2016. Amendments to Braskem Idesa Shareholders' Agreement In February 2010, Braskem and Idesa entered into a shareholders’ agreement, which we refer to as the Braskem Idesa shareholders’ agreement, to govern our relationship with respect to Braskem Idesa. In November 2012, Braskem and Idesa entered into the first amendment to the Braskem Idesa shareholders’ agreement, under which our ownership interest in Braskem Idesa was increased to 75% minus one share of the equity interest in Braskem Idesa and Idesa’s ownership interest in Braskem Idesa was reduced to 25% plus one share of the equity interest. In December 2012, we and Idesa entered into the second amendment to the Braskem Idesa shareholders’ agreement to include the commitment of both Sponsors to fund certain primary and secondary contingent equity to the project. In April 2015, we and Idesa entered into the third amendment to the Braskem Idesa shareholders’ agreement to include additional base equity contribution and reaffirm the new commitments of contingent equity, under which we agreed to fund up to 100% of the contingent equity commitment under the equity support agreement up to start-up date. The primary contingent equity commitment is US$208 million. In April 2017, we and Idesa amended and restated the Braskem Idesa shareholders’ agreement to update the terms to reflect the progress of the Company since the original signing in 2010 and to reflect the understanding among the shareholders as to the shareholders’ rights and obligations in connection with the payment of fees and interest by Idesa related to any funding by Braskem of Idesa’s portion of contingent equity or the working capital needs of Braskem Idesa, and the eventual dilution of Idesa’s equity interests in Braskem Idesa as a result of the same. In October, 2021, we and Idesa executed the second amendment and restatement shareholder agreement of Braskem Idesa in order to update the excess commitment fee regarding the contingent equity funded by us and modifying the fee rate related to it. Finally, in October 2024, a capitalization of the shareholders loan of R$8,771 million (US$1,548 million) was made. 136 Table of Contents Solution to import ethane for the Braskem Idesa facility in Mexico Braskem Idesa has been investing in logistics infrastructure to import ethane from the United States to maintain and increase the capacity utilization rate of its cracker. Concerning to ethane supply, Braskem Idesa has entered into a long-term agreement to acquire ethane and could also import in the sport market. To ensure the Fast-Track Solution’s feasibility, Braskem Idesa executed agreements with Smart Pass, a logistics operator, and with Enestas, a company specialized in cryogenic gas transportation. Smart Pass is responsible for receiving liquefied ethane at the Port of Coatzacoalcos docks and unloading it from the vessels in cryogenic tanks. Enestas is responsible for the transport of ethane by truck to the Braskem Idesa petrochemical complex, where the ethane is stored in existing tanks and regasified for use in the production process. With an approximate investment of R$49.9 million (US$9.6 million), this complementary solution for acquiring feedstock had made it possible to import up to 12,800 barrels per day of ethane to the Petrochemical Complex in Mexico, which represents 19% of its ethane needs. In February 2020, Braskem Idesa started its operation to import ethane (the “Fast Track Solution”) and imported its first shipment of ethane. The total investment in the Fast Track Solution, considering expansion, is an approximate total investment of R$67.5 million (US$12.1 million), with approximately R$55.2 million (US$9.9 million) spent by the end of 2020. The expansion of this complementary solution for acquiring feedstock makes it possible to import up to 35,000 barrels per day of ethane to the Petrochemical Complex in Mexico, which represents 50% of its ethane needs. In December 2020, Braskem Idesa concluded the first phase of expansion of the Fast Track Solution to 20 kbpd and, in April 2021 we concluded the second phase of expansion to a total capacity of 25 kbpd. By 2022 Braskem Idesa increased the total capacity up to 35,000 bpd as a result of additional investment of R$86.5 million (US$15.5 million). By 2024, our petrochemical complex had an operating rate of approximately 78% primarily due to the shortfall in ethane supplied under the ESA, which was partially offset by imported ethane supplied by the Fast Track Solution. We diversified our sources of feedstock supply with the Fast-Track Solution and we plan to increase our import capacity in the future by adding additional discharge stations, both at the port and at our plant. Once the Ethane Import Terminal is operational, we expect to not rely on the Fast-Track Solution. In addition, to implement the Fast-Track Solution, we executed the BNL Ethane Supply Agreement, a contract for the purchase of a target volume of ethane per year with Braskem Netherlands in February 2020, which has a term of twenty-four months, extendable for one optional period of six months. The price of ethane was determined by a contractual formula, and penalties would apply for delivery delays or if incorrect quantities are delivered. In addition, we have purchased additional volumes of ethane from Braskem Netherlands by entering into the BNL Ethane Supply Agreement Amendment. On December 18, 2023, Braskem Idesa entered into a term agreement for the purchase of ethane with Braskem Netherlands, B.V., substituted on January 1, 2024 for Braskem Trading & Shipping B.V. in effect until March 2033, using Mont Belvieu price reference, in order to import: (i) additional capacity of ethane to the ethane currently supplied by Pemex before Ethane Import Terminal becomes fully operational, and (ii) all ethane requirements of Braskem Idesa after Ethane Import Terminal become operational. For additional information, particularly relating to the risks associated with this project, please see “Item 3.D Risk Factors—Risks Relating to Mexico—We source part of our ethane feedstock from Pemex in Mexico, which we expect to be our primary source of ethane until the Ethane Import Terminal is operational.” On October 12, 2021, Braskem Idesa and Braskem Idesa Servicios incorporated Terminal Química Puerto México, S.A.P.I. under the laws of Mexico, with the main purpose of designing, constructing and developing the ethane import terminal and a pipeline that will connect the terminal directly to our Complex. In addition, on December 09, 2021, Braskem Idesa’s board of directors approved the Final Investment Decision (“FID”) in order to invest in the Ethane Import Terminal Project. The expected ethane capacity of the Ethane Import Terminal would be enough to fulfill the total ethane needs for the Mexico Complex. This terminal would provide the capacity to import more ethane than we currently require. With this, our Mexico Segment will be able to source the total needs of our Mexico Complex to increase our polyethylene production and take advantage of the forecasted increase in demand for polyethylene products in North America and around the world. 137 Table of Contents The estimated cost of the Ethane Import Terminal and related infrastructure investment is approximately R$3,592 million (US$580 million) (inclusive of financing costs and VAT).
