Gerdau is exposed to various market risks, which involve the fluctuation of exchange rates, interest rates and also commodities. The Company uses derivatives and other financial instruments to reduce the impact of such risks on its financial assets and liabilities or future cash flows and earnings. Gerdau has established policies to assess market risks and to approve the use of derivate financial instruments transactions related to those risks. The Company enters into derivative financial instruments to manage the above-mentioned market risks and never for speculative purposes. Exchange Rate Risk This risk is related to the possibility of fluctuations in exchange rates affecting the amounts of financial assets or liabilities or of future cash flows and income. The Company assesses its exposure to the exchange rate by measuring the difference between the amount of its assets and liabilities in foreign currency. The Company understands that the accounts receivables originated from exports, its cash and cash equivalents denominated in foreign currencies and its investments abroad are more than equivalent to its liabilities denominated in foreign currency. Since the management of these exposures occurs at each operation level, if there is a mismatch between assets and liabilities denominated in foreign currency, the Company may contract derivative financial instruments in order to mitigate the effect of exchange rate fluctuations. Foreign currency sensitivity analysis As of December 31, 2025, the Company was primarily exposed to fluctuations between the Real and the Dollar. The sensitivity analysis performed by the Company considers the effects of a 5% increase or decrease between the Real and the Dollar on its unhedged debt (loans and financing), accounts receivable from exports from Brazil, and import suppliers (imports/exports). Fluctuations between the local currencies of other countries and the Dollar do not represent material exposures. In this analysis, for foreign currency variations, if the Real appreciates against the Dollar, this would represent gain of R$ 217,347 (gain of R$ 124,447 as of December 31, 2024), if the Real depreciates against the Dollar, this would represent an expense of the same value. As for foreign currency variations in imports and exports, if the Real appreciates against the Dollar, this would represent gain of R$ 13,370 (loss of R$ 44,777 as of December 31, 2024), if the Real depreciates against the Dollar, this would represent an expense of the same value. The net values of other assets and other liabilities in foreign currencies do not present significant risks of impacts due to fluctuations in the exchange rate. 110 Table of Contents Sensitivity analysis of currency forward contracts As of December 31, 2025 and December 31, 2024, the Company has no exposure to forward contracts in US Dollars or Argentine Pesos against the US Dollar for any of its assets and liabilities. The US Dollar/Real forward contracts are intended to hedge asset and liability positions in US Dollars, and the mark-to-market effects of these contracts were recorded in the Consolidated Income Statement. Interest rate risk This risk arises from the effects of fluctuations in interest rates applied to the Company’s financial liabilities or assets and future cash flows and income. The Company evaluates its exposure to these risks: (i) comparing financial assets and liabilities denominated at fixed and floating interest rates and (ii) monitoring the variations of interest rates like SOFR and CDI. Accordingly, the Company may enter into interest rate swaps in order to reduce this risk. Interest rate sensitivity analysis The interest rate sensitivity analysis made by the Company considers the effects of an increase or reduction of 10 basis point (bps) on the average interest rate applicable to the floating part of its debt. The calculated impact, considering this variation in the interest rate totals R$ 43,547 as of December 31, 2025 (R$ 44,299 as of December 31, 2024) and would impact the Financial expenses account in the Consolidated Statements of Income. The specific interest rates to which the Company is exposed are related to the loans, financing, and debentures presented in Notes 15 and 16, and are mainly comprised by SOFR and CDI — Interbank Deposit Certificate. Price risk of commodities This risk is related to the possibility of changes in prices of the products sold by the Company or in prices of raw materials and other inputs used in the productive process. Since the Company operates in a commodity market, net sales and cost of sales may be affected by changes in the international prices of their products or materials. In order to minimize this risk, the Company constantly monitors the price variations in the domestic and international markets. Besides that, the Company may use derivative instruments for hedge purposes. As of December 31, 2025, the Company has exposure to commodity (energy) derivatives. The sensitivity analysis performed by the Company considers the effects of a 5% increase or decrease in the price of commodities, and their effects on the mark-to-market valuation of these derivatives. A 5% increase in the price of commodities represents revenue of R$ 4,130 (R$ 3,113 as of December 31, 2024), and a 5% decrease in the price of commodities represents an expense as of December 31, 2025 and December 31, 2024. The effects of the mark-to-market valuation of these derivatives were recorded in the Consolidated Income Statement. Credit risk This risk arises from the possibility of the Company not receiving amounts arising from sales to customers or investments made with financial institutions. In order to minimize this risk, the Company adopt the procedure of analyzing in details of the financial position of their customers, establishing a credit limit and constantly monitoring their balances. Regarding financial investments, the Company only carries out transactions with first-rate institutions and with low credit risk, as assessed by rating agencies and risk mitigation parameters defined in the Company’s internal guidelines. Capital management risk This risk comes from the Company’s choice in adopting a financing structure for its operations. The Company manages its capital structure, which consists of a ratio between the financial debts and its own capital (Equity) based on internal policies and benchmarks. The Key Performance Indicators (KPI) related to the “Capital Structure Management” objective are: WACC (Weighted Average Cost of Capital), Net Debt/EBITDA (Earnings before interest, income tax, depreciation and amortization), Coverage Ratio of Net Financial Expenses (EBITDA/Net Financial Expenses) and Debt/Total Capitalization Ratio. Net Debt is formed by the principal of the debt reduced by cash, cash equivalents and short-term investments (Notes 4, 15 and 16). Total Capitalization is formed by the Total Debt (composed of the principal of the debt) and the Equity (Note 23). The Company may change its capital structure, according to economic and financial conditions, in order to optimize its financial leverage and debt management. At the same time, the Company seeks to improve its ROCE (Return on Capital Employed) through the implementation of working capital management and an efficient program of investments in property, plant and equipment. 111 Table of Contents Liquidity risk The Company’s management policy of indebtedness and cash on hand is based on using the committed lines and the currently available credit lines with or without a guarantee in export receivables for maintaining adequate levels of short, medium, and long-term liquidity.

C.REASONS FOR THE OFFER AND USE OF PROCEEDS Not required, as the Company is filing this Form 20-F as an annual report. D.RISK FACTORS We are subject to various risks and uncertainties resulting from changing competitive, economic, political and social conditions that could harm our business, results of operations or financial condition. The risks described below could adversely affect our business, consolidated financial position, results of operations or cash flows. These risks are not the only ones we face. Other risks that we do not presently know about or that we presently believe are not material could also adversely affect us. Risks Relating to our Business and the Steel Industry Cyclical and Global Economic Volatility in Steel Demand The steel industry is highly cyclical and strongly influenced by global economic conditions. Fluctuations in demand, international prices, trade policies, and production overcapacity (particularly in major producing countries) create significant volatility in steel markets. Past events highlight this vulnerability: the (i) 2008–2009 global financial crisis led to a sharp decline in steel demand; (ii) the COVID-19 pandemic in 2020 caused severe disruptions before stimulus-driven recovery; and (iii) the U.S. tariff measures in 2025 further distorted trade flows and pressured international prices. These examples underscore how external shocks can quickly affect steel consumption, pricing, and global trade flows. Global crises, economic slowdowns, geopolitical tensions, and downturns in key consuming sectors such as construction and automotive can depress demand and prices, increase imports, and disrupt trade. In such environments, the Company may face reduced shipments, lower revenues, and margin compression. If the Company is unable to remain competitive under these shifting market conditions, its profitability and overall financial condition may be adversely affected. Our results and financial condition are affected by global and local market conditions that we do not control and cannot predict. Our results of operations and financial condition are subject to significant volatility due to global and local market dynamics beyond our control. The steel industry is inherently cyclical, and fluctuations in steel demand, pricing, and production costs can materially impact our profitability. A significant portion of our operations are concentrated in North America. As a result, our exposure to economic, political, and regulatory conditions in these markets has increased year over year. Changes in economic activity, interest rates, trade policies, currency fluctuations, or other market conditions in North America could adversely affect our business, financial condition, and results of operations. The range of economic factors influencing their markets is broad and often unpredictable, thereby increasing the potential impact on our operations. 3 Table of Contents Additionally, rising energy costs, constrains on raw material availability, and foreign exchange rate fluctuations can increase our operational expenses and reduce margins. External factors such as economic downturns, changes in infrastructure spending, supply chain disruptions, and shifts in global trade policies, including protectionist measures and tariffs, may also adversely affect our operations. Global economic weakness may prompt banks to limit or deny lending to us or to our customers, which could cause our customers to slow down or reduce their purchase of our products. This, in turn, could have a material adverse effect on our liquidity, operations, and our ability to carry out our announced capital investment programs. We may experience longer sales cycles, difficulty in collecting sales proceeds and lower prices for our products. We cannot provide any assurance that any of these events will not have a material adverse effect on market conditions, the prices of our securities, our ability to obtain financing and our results of operations and financial condition. Global conflicts and sanctions may adversely affect our operations and financial condition. Armed conflicts and geopolitical events may negatively impact demand for steel and iron ore, commodity prices, and energy costs. Sanctions imposed in connection with such conflicts, or any escalation thereof, could disrupt financial and commodity markets, restrict trade, and have long-lasting effects beyond the duration of the conflicts. These factors may materially and adversely affect our business, results of operations, and financial condition. The continuing Russian invasion of Ukraine, conflict on the border between Israel and the Gaza strip, the U.S. attack in Iran, the ongoing economic, political and humanitarian crisis in Venezuela, and the sanctions imposed (and further sanctions that may be imposed) could have further destabilizing effects on financial markets and certain commodity markets. Any substantial escalation would have a material adverse effect on macroeconomic conditions. In addition, sanctions may remain in place beyond the duration of any military conflict and have a long-lasting impact regionally and globally and could adversely impact the Company’s results of operations and financial condition. Any other global conflicts could have a material adverse effect on the overall macroeconomic environment, impacting financial markets and certain commodity markets, with a materially adverse impact on our results of operations and financial condition. Gerdau faces significant competition in relation to its steel products, including prices of other domestic and foreign producers, which may adversely affect its profitability and market share. The global steel industry is highly competitive with respect to price, quality of products and customer service, as well as to technological advances that allow the reduction of production costs. Brazilian exports of steel products are influenced by several factors, including protectionist policies of other countries, foreign exchange policy and the growth rate of the world economy. Moreover, continuous advances in material sciences and the resulting technologies facilitate the improvement of products such as plastic, aluminum, ceramics, glass and timber, permitting them to serve as substitutes for steel. Due to the high initial investment costs, the operation of a steel plant on a continuous basis may encourage mill operators to maintain high production levels, even in periods of low demand, which increases the pressure on industry profit margins. That said, competitive pressures that force the fall of steel prices can also affect the profitability of Gerdau. The steel industry has historically suffered from excess of production capacity, which has worsened due to a substantial increase in production capacity in emerging countries, particularly China and India and other emerging markets. China is currently the largest global steel producer. Unfavorable conditions in China and steel-exporting countries can significantly impact steel prices in other markets. China, as the world’s largest steel producer and consumer, influences global steel demand and supply dynamics. Factors like a lack of real estate investment, lower consumer confidence and rationalization of government stimulus can diminish steel demand within China, affecting global prices. Additionally, steel-exporting countries, benefiting from lower production costs, efficient supply chains, and economies of scale, can exert competitive pressures on international steel prices, particularly when coupled with government subsidies or trade agreements. These combined factors create a complex interplay of supply and demand forces that can swiftly impact steel prices worldwide. 4 Table of Contents In 2023, 2024 and 2025, steel companies in Brazil faced strong competition from imported products, mainly due to the global excess in steel production, culminating in an unhealthy market capture near the record highs, increasing the competitive imbalance, mainly driven by predatory steel imports from China. According to the Brazil Steel Institute, steel imports in Brazil reached 6.4 million tonnes in 2025, up 7.4% over 2024, which has harmed fair competition in the Brazilian markets where Gerdau operates in the country and impacted the Company’s results. Although Gerdau is a modern and highly efficient producer, the Company cannot compete with heavily subsidized imports, which may adversely affect the competitiveness of the industry, its financial condition, and results of operations in the future. An increase in China’s steelmaking capacity or a slowdown in China’s steel consumption could have a material adverse effect on domestic and global steel pricing and could result in increased steel imports into the markets in which the Company operates. One significant factor in the global steel market has been China’s high steel production capacity. However, very substantial consumers of steel have lost relevance in the Chinese economy, causing a deep and structural imbalance between steel supply and demand in the Chinese domestic market. China is currently the world’s largest steel producer and has favorable conditions such as excess steel capacity, devalued currency and a job maintenance policy. In addition, the Chinese government subsidizes surplus steel production, exporting these volumes at prices below production costs in several countries in the transoceanic region that have not yet taken sufficient trade defense measures against trade practices that enable predatory steel imports, such as Brazil, and consequently pushing down international steel prices. Trade defense measures against predatory practices are legal and supported by the World Trade Organization. Some countries such as the United States, Mexico, Colombia, Turkey, Vietnam and the 27 countries of the European Union have adopted relevant measures to combat the entry of subsidized Chinese steel, strengthening their economies, their industries, and their jobs. In 2025, steel imports in Brazil increased by 7.4% compared to 2024 and reached for the third straight year a record volume in the annual historical series, according to the Brazil Steel Institute. Over 2023,2024 and 2025, Gerdau faced again an increase in the penetration of imported steel in Brazil, particularly from China. For these reasons, players in the sector have been defending the need for a review of import tariffs in Brazil to ensure fairer and more competitive conditions for the national steel market. The Brazilian government partially addressed the steel sector since 2024 with a temporary hike of tariffs for some flat and long steel products utilizing a quota system, which proved insufficient so far. If the Brazilian government does not enhance measures against subsidized steel imports and the high level of imports continues without adequate measures that guarantee fair competition with the local market, Gerdau’s financial condition and results of operations may be negatively affected in the future. In addition to direct steel imports, the Brazilian industry also faces competition from imported finished products, which negatively affects the entire steel supply and production chain. Higher steel scrap prices or a reduction in supply could adversely affect production costs and operating margins. The main metal input for the Company’s mini mills is steel scrap. Although international steel scrap prices are determined essentially by scrap prices in the U.S., due to the United States being the main scrap exporter in the world, scrap prices in the Brazilian market are set by domestic suppliers and demand and by scrap exports to India, the main destination to Brazilian scrap exports. The price of steel scrap in Brazil varies from region to region and reflects supply, demand and transportation costs. Should scrap prices increase significantly without a corresponding increase in finished steel selling prices, the Company’s profits and margins could be adversely affected. An increase in steel scrap prices or a shortage in the supply of scrap to its units would affect production costs and potentially reduce operating margins and revenues. As a result, the Company’s financial condition and results of operations may be adversely affected. Increases in iron ore and coal prices, or reductions in market supply, and price increases in other inputs, could adversely affect the Company’s operations. When the prices of raw materials, particularly iron ore and coking coal, increase, and the Company needs to produce steel in its integrated facilities, the production costs in its integrated facilities also increase. The Company uses iron ore to produce hot pig iron at its Ouro Branco and Divinópolis mills located in the state of Minas Gerais. The Ouro Branco mill is the Company’s largest mill in Brazil, and its main metal input to produce steel is iron ore. This unit represented 55.2% of the total crude steel output (in volume) of the Brazil Business Segment in 2025. A shortage of iron ore in the domestic market may adversely affect the steel producing capacity of the Brazilian units, and an increase in iron ore prices could reduce profit margins. 5 Table of Contents The Company has iron ore mines in the Brazilian state of Minas Gerais. To mitigate its exposure to the volatility in iron ore prices, the Company invested in expanding the production capacity of these mines. All the Company’s coking coal requirements for its Brazilian unit at Ouro Branco are sourced domestically or imported. Coking coal is the main energy input at the Ouro Branco mill and is used at the coking facility and blast furnaces. Although this mill is not dependent on coke supplies, a contraction in the supply of coking coal could adversely affect the integrated operations at this site. The coking coal used in this mill is imported from Colombia, the United States and Russia. A shortage of coking coal in the international market would adversely affect the steel producing capacity of the Ouro Branco mill. To minimize the risks of shortages the Company has secured volumes under long-term contracts with negotiable indexed or fixed prices. In addition, an increase in prices could reduce profit margins. Another related risk is the currency depreciation to which the Ouro Branco Mill is exposed, since all coking coal consumed by the operation is imported. Volatility in the supply and prices of these and other raw materials, energy and transportation, could adversely affect the Company’s results of operations. We are vulnerable to inflationary cost pressures, especially in relation to the prices of electricity, natural gas and CO2. Such events could adversely affect the Company’s financial condition and results of operations. Risks Relating to our Operations The Company’s projects are subject to risks that may result in increased costs or delay or prevent their successful implementation. The Company has made investments to further enhance the productivity of its operations. These projects are subject to several risks that may adversely affect the Company’s growth prospects and profitability, including the following: ● the Company may encounter delays, availability problems or higher than expected costs in obtaining the necessary equipment, services and materials to build and operate a project; ● the Company’s efforts to develop projects according to schedule may be hampered by a lack of infrastructure, including availability of overburden and waste disposal areas as well as reliable power and water supplies; ● the Company may fail to obtain, may lose, or experience delays or higher than expected costs in obtaining or renewing the required permits, authorizations, licenses, concessions and/or regulatory approvals to build or continue a project; and ● changes in market conditions, laws or regulations may make a project less profitable than expected or economically or otherwise unfeasible. Any one or a combination of the factors described above may materially and adversely affect the Company’s financial condition and results of operations. Unexpected equipment failures may lead to production curtailments or shutdowns. Unexpected interruptions in the production capabilities at Gerdau’s principal sites and installations would increase production costs, reducing shipments and earnings for the affected period. These interruptions result from: (i) unpredictable/periodic equipment failures, which are essential to the development of the production processes of Gerdau, such as steelmaking equipment, its electric arc furnaces, continuous casters, gas-fired reheat furnaces, rolling mills and electrical equipment, including high-output transformers; and/or (ii) unanticipated events such as fires, explosions or severe weather conditions. As a result, Gerdau has experienced, and may in the future experience, material plant shutdowns or periods of reduced production. Unexpected interruptions in production capabilities would adversely affect Gerdau’s productivity and results of operations. Moreover, any interruption in production capability may require Gerdau to make additions to fixed assets to remedy the problem, which would reduce the amount of cash available for operations. Gerdau’s insurance may not cover the losses. In addition, long-term business disruption could harm the Company’s reputation and result in a loss of customers, which could adversely affect the business, results of operations, cash flows and financial condition. 6 Table of Contents Failure to obtain the necessary permits and licenses could adversely affect our operations. We depend on the issuance of permits and licenses from governmental agencies to undertake some of our activities that are considered polluting or potentially polluting. For obtaining said licenses, certain investments in conservation are required to offset any such impact. The operational licenses require, among other things, that we periodically report our compliance with emissions standards set by environmental agencies. Failure to obtain, renew or comply with our operating licenses may cause delays in our deployment of new activities, increased costs, monetary fines or even suspension of the affected activity, which may materially adversely affect us. The Company’s operations are energy-intensive, and energy shortages or higher energy prices could have an adverse effect on the Company’s financial condition and results of operations. Crude steel production is an energy-intensive process, especially in melt shops with electric arc furnaces. Electricity represents an important production component at these units, as does natural gas, although to a lesser extent. Electricity cannot be replaced at Gerdau’s mills and power rationing, or shortages, could adversely affect production at those units. As a result, the Company’s financial condition and results of operations may be adversely affected. Layoffs in the Company’s labor force could generate costs or negatively affect the Company’s operations. A substantial number of our employees are represented by labor unions and are covered by collective bargaining or other labor agreements, which are subject to periodic negotiation. Strikes or work stoppages have occurred in the past and could reoccur in connection with negotiations of new labor agreements or during other periods for other reasons, including the risk of layoffs during a down cycle that could generate severance costs. Moreover, the Company could be adversely affected by labor disruptions involving unrelated parties that may provide goods or services to the Company. Strikes and other labor disruptions at any of the Company operations could adversely affect the operation of facilities and the timing of completion and the cost of capital of our projects. Throughout 2025, the Company implemented workforce reductions. These measures were primarily driven by the significant increase in predatory steel imports into the Brazilian market, which adversely affected domestic production levels. If the Brazilian government does not implement measures against subsidized steel and the high level of imports persist without measures that guarantee fair competition with the local market, Gerdau may consider restructuring its operations in Brazil. This could involve shutdown of some other production capacities and, consequently, a recalibration of the workforce size, materially adversely affecting the financial condition and results of operations of the Company. We could be harmed by a failure or interruption of our information technology systems or automated machinery. We rely on our information technology systems and automated machinery to effectively manage our production processes and operate our business. Advanced technological systems and machinery are nonetheless subject to defects, interruptions and breakdowns. Any failure of our information technology systems and automated machinery to perform as we anticipate could disrupt our business and result in production errors, processing inefficiencies and the loss of sales and customers, which in turn could result in decreased revenue, increased overhead costs and excess or out-of-stock inventory levels resulting in a material adverse effect on our business results. Although we have procedures in place to prevent and minimize the impact of a potential failure, including a data back-up system for our management systems, 24/7 monitoring of our servers, and a cybersecurity program that maintains a Corporate Information Security Policy and a Data Privacy Policy in place, there is no assurance that these will work properly or that there will not be an impact on our results of operations or financial condition. In addition, our information technology systems and automated machinery may be vulnerable to damage or interruption from circumstances beyond our control, including fire, natural disasters, systems failures, viruses, cyber-attacks and other security breaches, including breaches of our production processing systems that could result in damage to our automated machinery, production interruptions or access to our confidential financial, operational or customer data. Any such damage or interruption could have a material adverse effect on our business results, including as a result of our facing significant fines, customer notice obligations or costly litigation, harming our reputation with our customers or requiring us to spend significant time and expense developing, repairing or upgrading our information technology systems and automated machinery. 7 Table of Contents Further, while we have some backup data-processing systems that could be used in the event of a failure of our primary systems, we do not yet have a disaster recovery plan or a backup data center that covers all of our units. While we endeavor to prepare for failures of our network by providing backup systems and procedures, we cannot guarantee that our current backup systems and procedures will operate satisfactorily in the event of a regional emergency. Any substantial failure of our backup systems to respond effectively or on a timely basis could have a material adverse effect on our business and results of operations. We are subject to information technology risks related to breaches of security pertaining to sensitive company, customer, employee and vendor information as well as breaches in the technology used to manage operations and other business processes. Cybersecurity is a significant concern due to the importance of information technology to the successful conduct of our business operations.We have an executive dedicated to leading the Information Security and Data Protection effort as well as an internal team with qualified specialists and analysts to conduct and evaluate the adequacy of the security and data protection controls. Additionally, we also have an incident response service provider to support our team to prevent and respond to cyber incidents. We rely upon secure information technology systems for data capture, processing, storage and reporting. Despite careful security and controls design, implementation, updating and independent third-party verification, that also includes specific policies, procedures, and specialized software tools for cybersecurity and data protection, our information technology systems, and those of our third-party providers, could become subject to employee error or malfeasance, natural disasters or be susceptible to cyberattacks. Network, system, application, and data breaches could result in operational disruptions or information misappropriation. Access to internal applications required to plan our operations, source materials, manufacture and goods and account for orders could be denied or misused. Theft of intellectual property or trade secrets, and inappropriate disclosure of confidential company, employee, customer or vendor information, could stem from such incidents. Any of these operational disruptions and/or misappropriation of information could result in lost sales, business delays, negative publicity and could have a material effect on our business. We also could be required to spend significant financial and other resources to remedy the damage caused by a security breach, including repairing or replacing networks and information technology systems, liability for stolen information, increased cybersecurity protection costs, litigation expense and increased insurance premiums. Outbreaks of disease and health epidemics could have a negative impact on our business revenues and results of operations. The Company monitors the outbreaks of disease and health epidemics and the impacts these may have on the routines of employees, contractors, suppliers, customers and other business partners who may be prevented from conducting certain business activities for an indefinite period. These effects include shutdowns that may be requested or mandated by governmental authorities or otherwise elected by companies as a preventive measure. In addition, mandated government authority measures or other measures elected by companies as preventative measures may lead to our customers being unable to complete purchases or other activities. Demand for our steel products is directly linked to overall economic activity within those international markets in which we sell our products. A decline in the level of activity in either the domestic or the international markets within which we operate as a result of future outbreaks of disease and health epidemics and related measures to contain them could adversely affect and impact both the demand and the price of our products and have a material adverse effect on us. Furthermore, the nature of our business is complex and, to keep operating, most of our work cannot be performed remotely. Our focus is on protecting the health of our employees and, therefore, we encourage them to take care of their health, since operational continuity is key to people’s jobs, to local communities and to the economies of the countries and regions where we operate. Risks Relating to our Mining Operations Estimates of Gerdau’s mineral resources are based on interpretations and assumptions, involving a level of uncertainty, and may differ substantially from the quantities that can be extracted. Gerdau’s mineral resources refer to estimated quantities of iron ore and minerals. In 2023, Gerdau received the certification report for the iron ore reserves at the mine located in Miguel Burnier District, municipality of Ouro Preto (MG - Brazil). The report was prepared by the independent certifier SRK Consulting, and according to the report, the Company had certified reserves of 476 million dry metric tons of iron ore, comprised of 138 million tonnes of proven reserves and 338 million tonnes of probable reserves. These mining operations are part of Brazil Business Segment, with the focus on supplying iron ore for it. 8 Table of Contents Notwithstanding the report, there are several uncertainties that are inherent to such estimates of resources, including many factors that are beyond our control, such as geological and technological factors. All estimates of Gerdau’s mineral resources and reserves are based on interpretations and assumptions that involve a level of uncertainty. If the amount of mineral resources that actually can be extracted differs materially from our estimates, our business, results of operations and financial condition could be materially adversely impacted. The Company has one mining dam for the disposal of tailings, and any accident or defect that affects the structural integrity could affect its image, operating results, cash flows and financial condition. Gerdau has one mining dam, downstream, for the disposal of tailings in the state of Minas Gerais, the Alemães Dam, which has been in operation since 2011 and is regularly monitored. In 2023, this structure had its construction methodology changed to downstream heightening from originally upstream heightening, and therefore fully complying with the Brazilian regulations. Furthermore, following Gerdau’s decision, the tailings disposal at the Dam was ceased by February 2023, and therefore the Company is disposing 100% of its tailings through dry stacking. The Alemães Dam is classified as Class B (low risk) in accordance with the National Mining Dam Registry available on the website of the National Mining Agency (ANM). Gerdau adopts rigorous standards for engineering control and environmental supervision and conducts a half-yearly Geotechnical Stability Audit to ensure the stability of the dam. Gerdau maintains Mining Dam Emergency Action Plans that are filed at the regulatory agencies, as required by applicable regulations. The Company also has other structures that are treated as Mining Dams by the ANM: UTM 2 Bays, North Dike of Waste Pile 01, and North and South Bays of Waste Pile A. These are structures that receive stormwater runoff and/or effluents from drainage at the Ore Treatment Units to enable the sedimentation of solid waste before the water is returned to the environment. An accident involving any of these dams could have serious adverse consequences, including: ● Temporary/permanent shutdown of mining activities and consequently the need to buy iron ore to supply mills; ● High expenditures on contingencies and on recovering the regions and people affected; ● High investments to resume operations; ● Payment of fines and damages; and ● Potential environmental impacts. Any of these consequences could have a material adverse impact on the Company’s operating results, cash flow and financial condition. Financial Risks Any downgrade in the Company’s credit ratings could adversely affect the availability of new financing and increase its cost of capital. In 2007, the international rating agencies, Fitch Ratings and Standard & Poor’s, classified the Company’s credit risk as “investment grade”, enabling the Company to access more attractive borrowing rates. During reviews in 2025, despite a lower local sovereign credit rating, the Company maintained its investment grade rating with S&P (BBB), Fitch (BBB) and Moody’s (Baa2) with Moody’s with stable outlook, reflecting the Company’s history of conservative capital allocation, combined with the expectation of robust operating performance throughout the year. The loss of any one or more of Gerdau’s investment grade ratings could increase its cost of capital, impair its ability to obtain capital and adversely affect its financial condition and results of operations. 9 Table of Contents The Company’s level of indebtedness could adversely affect its ability to raise additional capital to fund operations, limit the ability to react to changes in the economy or the industry and prevent it from meeting its obligations under its debt agreements. The Company’s degree of leverage, together with a resulting change in rating by the credit rating agencies, could have important consequences, including the following: ● It may limit the ability to obtain additional financing for working capital, additions to fixed assets, product development, debt service requirements, acquisitions and general corporate or other purposes; ● It may limit the ability to declare dividends on its shares; ● A portion of the cash flows from operations might be dedicated to the payment of interest on existing indebtedness and would not be available for other purposes, including operations, additions to fixed assets and future business opportunities; ● It may limit the ability to adjust to changing market conditions and place the Company at a competitive disadvantage compared to its competitors that have less debt; ● The Company may be vulnerable in a downturn in general economic conditions; and ● The Company may be required to adjust the level of funds available for additions to fixed assets. As a result, the Company’s financial condition and results of operations may be adversely affected. Variations in the foreign exchange rates between the U.S. dollar and the currencies of countries in which the Company operates may increase the cost of servicing its debt denominated in foreign currency and adversely affect its overall financial performance. The Company’s results of operations are affected by fluctuations in the foreign exchange rates between the Brazilian real, the currency in which the Company prepares its financial statements, and the currencies of the countries in which it operates. For example, the North America Business Segment reports its results in U.S. dollars. Therefore, fluctuations in the exchange rate between the U.S. dollar and the Brazilian real could affect its results of operations. The same occurs with all other businesses located outside Brazil with respect to the exchange rate between the local currency of the respective subsidiary and the Brazilian real. Export revenue and margins are also affected by fluctuations in the exchange rate of the U.S. dollar and other local currencies of the countries where the Company produces in relation to the Brazilian real. The Company’s production costs are denominated in local currency, but its export sales are generally denominated in U.S. dollars. Revenues generated by exports denominated in U.S. dollars are reduced when they are translated into Brazilian real in periods during which the Brazilian currency appreciates in relation to the U.S. dollar. The Brazilian real appreciated against the US dollar by 5.3% in 2022 and by 8.0% in 2023. In 2024, the Brazilian real depreciated against the US dollar by 21.8%. In 2025, the Brazilian real appreciated against the US dollar by 11.1%. To date in 2026, the Brazilian real has appreciated against the US dollar by 6.4% by the beginning of March 2026. The Company held debt denominated in foreign currency, mainly U.S. dollars, in an aggregate amount of R$ 8.0 billion on December 31, 2025, representing 56% of its consolidated gross debt (loans, financings, and debentures). Significant further depreciation in the Brazilian real in relation to the U.S. dollar or other currencies could reduce the Company’s ability to service its obligations denominated in foreign currencies, particularly since a significant part of its net sales revenue is denominated in Brazilian reais. As a result, the Company’s financial condition and results of operations may be adversely affected. See Note 15 - Short-Term Debt and Long-Term Debt in its Consolidated Financial Statements included herein for further details. Exchange rate instability also may adversely affect the amount of dividends we can distribute to our shareholders, including the holders of our ADSs and the market price of our shares and ADSs. 10 Table of Contents We are involved in several tax, environmental, civil and labor disputes involving significant monetary claims. Unfavorable outcomes in judicial, administrative and regulatory litigation may negatively affect our results of operations, cash flows and financial condition. In the ordinary course of our business dealings, we are, and may become, party to numerous tax, environmental, civil and labor disputes involving, among other remedies, significant monetary claims. An unfavorable outcome against us may result in our being required to pay substantial amounts of money, including penalties and interest, which could materially adversely affect our reputation, results of operations, cash flows and financial condition. For certain of these legal proceedings and claims, we have not established a provision on our balance sheet or have only established provisions for part of the amounts in question, based on our external or internal counsels’ judgment as to the likelihood of an outcome unfavorable to us. Additionally, the amounts provisioned for legal proceedings may increase and existing provisions may become insufficient due to unfavorable outcomes in disputes against us. Although we are contesting existing proceedings and claims, the outcome of each specific proceeding and claim is uncertain and may result in obligations that could materially and adversely affect us. For further information concerning the principal pending matters, see Item 5.E - “Provisions for tax, civil and labor claims”, Item 8.A - “Legal Proceedings” and Note 19 – “Tax, Civil and Labor Claims and Contingent Assets” to the Consolidated Financial Statements appearing elsewhere in this Annual Report. Default by our clients or not receiving amounts invested with financial institutions could adversely affect the Company’s financial condition. Gerdau may suffer losses from the default of our clients. Gerdau has a broad base of active clients and, in the case of default of a group of clients, Gerdau may suffer an adverse effect on its business, financial condition, results of operations and cash flows. This risk arises from the possibility of the Company not receiving amounts arising from sales to customers or investments made with financial institutions, which could also have an adverse effect on the business, financial condition, results of operations and cash flows of Gerdau. Regulatory Risks Restrictive measures on trade in steel products may affect the Company’s business by increasing the price of its products or reducing its ability to export. This could adversely affect its business operations, financial condition and results of operations. Gerdau is a steel producer that supplies both the domestic market where it operates and several other international markets. The Company’s exports face competition from other steel producers, as well as restrictions imposed by importing countries in the form of quotas, ad valorem taxes, tariffs or increases in import duties, any of which could increase the costs of products and make them less competitive or prevent Gerdau from selling in these markets. There are no assurances that importing countries will not impose quotas, ad valorem taxes, tariffs or increase import duties, which could adversely affect the Company’s financial condition and results of operations. Conversely, restrictive measures on trade might positively impact the domestic steel demand in markets where Gerdau operates. An example of that scenario is the steel import tariffs reinstated by the Trump administration in early 2025. Effective March 12, 2025, the administration mandated that steel imports from several countries—including Canada, Mexico, the European Union, Japan, South Korea, the United Kingdom, Argentina, Australia, and Brazil—be subject to a 25% tariff. Following the initial reinstatement, trade policy tightened further when these tariffs were increased to 50% in June 2025 (with the exception of the UK, which remained at 25% pending trade negotiations). This series of measures represented a significant shift in U.S. trade policy, moving away from negotiated agreements and exemptions toward a more universal tariff structure. These decisions aimed to curb surging imports, address circumvention concerns, and strengthen domestic steel production. Gerdau believes that the trade defense measures aimed at strengthening the U.S. industry will influence greater capacity utilization and further improve the competitiveness of the Company’s operations in the U.S. The revised 50% import tariffs have addressed the exceptions resulting from Section 232, where previously only approximately 20% of the steel shipments imported to the United States were subject to tariffs. The current shift in U.S. trade policy is still developing, and therefore there are no assurances that the 50% tariffs favoring domestic steel production will not be lifted, altered, or significantly weakened—whether by legal challenges, new legislation, additional executive actions, or other means. However, a recent U.S. Supreme Court decision invalidating certain tariffs imposed under emergency economic powers is not expected to affect the steel tariffs implemented under Section 232. Nevertheless, if these tariffs were to be lifted or significantly weakened, it is likely that foreign steel imports would rise, leading to a decrease in U.S. steel prices. This change could have a significant negative impact on our revenues, financial performance, and cash flow. On the other hand, with the new tax on steel exports, Brazil could face a challenging period, especially as it is a major exporter of semi-finished products to the United States. In addition, Brazil could face increased imports due to higher tariffs in other markets and the ineffectiveness of the current quota-tariff system. 11 Table of Contents Costs related to compliance with environmental regulations could increase if requirements become stricter, which could have a negative effect on the Company’s results of operations. The Company’s industrial units and other activities must comply with a series of federal, state and municipal laws and regulations regarding the environment and the operation of plants in the countries in which they operate. These regulations include procedures relating to control of air emissions, disposal of liquid effluents and the handling, processing, storage, disposal and reuse of solid waste, hazardous or not, as well as other controls necessary for a steel company and with mining activities. Non-compliance with environmental and regulatory laws and regulations could result in administrative, civil or criminal sanctions and closure orders, in addition to the obligation of repairing damage caused to third parties and the environment, such as clean-up of contamination. If current and future laws become stricter, spending on fixed assets and costs to comply with legislation could increase and negatively affect the Company’s financial condition. Moreover, future acquisitions could subject the Company to additional spending and costs to comply with environmental and regulatory legislation. As a result, the Company’s financial condition and results of operations may be adversely affected. Laws and regulations to reduce greenhouse gases and other atmospheric emissions could be enacted in the near future, with significant, adverse effects on the results of the Company’s operations, cash flows and financial condition. The Company expects operations overseas to be affected by future federal, state and municipal laws related to climate change, seeking to deal with the question of GHG and other atmospheric emissions. Thus, one of the possible effects of this increase in legal requirements could be an increase in energy costs. As a result, the Company’s financial condition and results of operations may be adversely affected. A significant number of scientists, environmentalists, international organizations, regulators and other commentators sustain that global climate change has contributed, and will continue to contribute, to the increasing unpredictability, frequency and severity of natural disasters (including, but not limited to, hurricanes, droughts, tornadoes, freezes, other storms and fires) in certain parts of the world. As a result, several legal and regulatory measures as well as social initiatives have been introduced in numerous countries in an effort to reduce carbon dioxide and other greenhouse gas (GHG) emissions and combat global climate change. Such reductions in GHG emissions could result in increased energy, transportation and raw material costs and may require us to make additional investments in facilities and equipment. Although we cannot predict the impact of changing global climate conditions without certain assumptions, or of legal, regulatory and social responses to concerns about global climate change, any such occurrences may negatively affect our business, financial condition, results of operations and cash flows. Laws and regulations seeking to reduce GHG emissions can be enacted in the future, which could have a significant adverse impact on the operating results, cash flows, and the financial condition of the Company. One of the possible effects of the expansion of GHG emissions reduction requirements is an increase in costs, mainly resulting from the demand for renewable energy and the implementation of new technologies in the productive chain. On the other hand, demand is expected to grow constantly for recyclable materials such as steel, which, being a product that could be recycled numerous times without losing its properties, results in lower emissions during the lifecycle of the product. On December 11, 2024, the carbon market in Brazil was regulated by law, establishing the Brazilian Emissions Trading System (SBCE). Penalties can be applied for non-compliance. The implementation will occur in five phases, starting with the regulation, and the last one being the full implementation, which is expected to take at least four years from the regulation date. Penalties can be applied for non-compliance once they are in force. At state levels, there are demands for accounting for the inventory of GHG emissions and reporting to regulatory bodies as well as discussions about decarbonization strategies. In the U.S., future federal and/or state carbon regulation potentially presents impacts to our operations. To date, the U.S. Congress has not legislated carbon constraints, and near-term passage of any federal domestic carbon tax appears unlikely. In terms of a carbon tax on imported goods, the U.S. has not yet enacted a federal carbon border adjustment, but the issue is being considered in Congress. There are bipartisan bills and proposals in play that would impose fees on imports based on their carbon intensity, especially as other major economies (like the EU) have already adopted similar mechanisms. Passage is possible but unlikely in the near-term and likely to depend on negotiation with trade allies and industry stakeholders. Also, additional state regulations, such as those adopted in California, may impact Gerdau from 2026, imposing additional reporting obligations when the Company transacts business in these states. 12 Table of Contents The Inflation Reduction Act (“IRA”), passed by the U.S. Congress in August 2022. The 2025 Budget Reconciliation Bill significantly curtailed IRA clean energy tax credits, accelerating phase-outs for wind and solar, and imposing other restrictions that have contributed to renewable energy industry uncertainty and investment challenges. The renewable energy sector represents a significant and growing market for Gerdau’s products. Mexico has advanced in consolidating its carbon market, through an Emissions Trading System (ETS) and it could affect our operations in the future. The Brazilian Securities and Exchange Commission (CVM) has published resolutions referring to the adoption of IFRS S1 and S2 standards, which are part of the International Financial Reporting Standards (IFRS) issued by the International Sustainability Standards Board (ISSB). The standards are focused on the disclosure of information related to, respectively, sustainability and climate risks and opportunities, when it is financially material. The voluntary adoption of these standards began in January 2024, and mandatory adoption is scheduled for January 2026. The European Union (EU) Carbon Border Adjustment Mechanism (CBAM) aims to avoid “carbon leakage”, ensuring that its climate policies are not undermined by production relocating to countries with less ambitious green standards or by the replacement of EU products by more carbon-intensive imports. EU has the EU Emissions Trading System (ETS) in place. EU importers of some goods, including steel will have to report on the volume of their imports and GHG emissions embedded during their production, but without paying any financial adjustment at this stage. The transitional phase, which started in October 2023, will last until 2026, when the definitive period starts. As of that date, importers will need to buy and surrender the number of “CBAM certificates” corresponding to the GHG emissions embedded in imported CBAM goods. This new mechanism will not only impact our operations, which may lead to increased costs for our customers who are importers, but it can also shift the flow of steel products. Any products that do not meet the criteria set forth by the CBAM or any other future mechanism will be less competitive in these markets. However, they may still be accepted in countries or regions without a carbon border adjustment mechanism in place, resulting in an increase in the volume of steel with less ambitious green standards in the market. This will lead to competition with steel that is differentiated based on GHG emissions. Legislation related to air quality and atmospheric emissions in Brazil influence management, monitoring, and reporting practices. Operations subject to these requirements must maintain full compliance, as noncompliance may lead to penalties and other regulatory consequences. As a result of these rules, our legal, accounting, and other compliance expenses may increase significantly, and compliance efforts may divert management time and attention. We may also be exposed to legal or regulatory action or claims as a result of these new regulations. Although the Company is in the process of evaluating the new rules, some of these risks could have a material adverse effect on our business, financial condition, results of operations and the prices of our securities. Our operations expose us to risks and challenges associated with conducting business in compliance with applicable anti-bribery, anti-corruption and antitrust laws and regulations. We have operations in Brazil and other countries in South America and North America. We face several risks and challenges inherent in conducting business internationally, where we are subject to a wide range of laws and regulations such as the Brazilian Anti-Corruption Law (Law 12,846/2013), Antitrust Law (Law 12,529/2011), the U.S. Foreign Corrupt Practices Act, or FCPA, and similar anti-bribery, anti-corruption and antitrust laws in other jurisdictions. In recent years, there has been an increased focus on corruption in Brazil and the investigation and enforcement activities of the United States under the FCPA and by other governments under similar laws and regulations. These laws generally prohibit corrupt payments to governmental officials and certain payments, gifts or remunerations to or from clients and suppliers. Violations of these laws and regulations could result in fines, criminal penalties and/or other sanctions against the Company, our officers or our employees, requirements to impose more stringent compliance programs, and prohibitions on the conduct of the Company’s business and our ability to participate in public biddings. The Company may incur expenses and must recognize provisions and other charges in respect of such matters. In addition, the increased attention focused upon liability issues because of investigations, lawsuits and regulatory and environmental proceedings could harm our brand or otherwise impact the growth of our business. The retention and renewal of many of our contracts depend on creating a sense of trust with our customers and any violation of these laws and regulations may irreparably undermine that trust and may lead to termination of such relationships, as well as having a material adverse effect on our financial condition and results of operations. If any of these risks materialize, our reputation, strategy, international expansion efforts and our ability to attract and retain employees could be negatively impacted, and, consequently our business, financial condition and results of operations could be adversely affected. 13 Table of Contents Our governance and compliance processes may fail to prevent regulatory penalties and reputational harm. The Company operates in a global environment and our activities extend over multiple jurisdictions and complex regulatory frameworks, with increased enforcement activities worldwide. Our governance and compliance processes, which include the review of internal controls over financial reporting, may not be able to prevent future breaches of legal, accounting or governance standards. We may be subject to breaches of our Code of Ethics and Conduct, anti-corruption policies and business conduct protocols, as well as to cases of fraudulent behavior, corrupt practices and dishonesty by our employees, contractors and other agents. The Company’s failure to comply with applicable laws and other standards could subject it to fines, loss of operating licenses and reputational harm. Risks Relating to Brazil Any further downgrading of Brazil’s credit rating could adversely affect the price of our shares. We can be adversely affected by investors’ perceptions of risks related to Brazil’s sovereign debt credit rating. Rating agencies regularly evaluate Brazil and its sovereign ratings, which are based on several factors including macroeconomic and industry trends, fiscal and budgetary conditions, indebtedness metrics and the perspective of changes in any of these factors. On July 26, 2023, Fitch Ratings upgraded Brazil’s sovereign rating to “BB” from “BB-” and subsequently affirmed the rating at “BB” with a stable outlook in June 2025, citing the country’s resilient and diversified economy, strong external finances and deep local markets, balanced against fiscal challenges and rising government debt. On December 19, 2023, S&P Global Ratings upgraded Brazil’s sovereign credit rating to “BB” from “BB-”, reflecting structural reforms and a strong external position. In June 2025, S&P affirmed Brazil’s “BB” rating with a stable outlook, supported by robust external accounts and domestic capital markets, although constrained by persistent fiscal deficits and a high debt burden. On October 1, 2024, Moody’s Ratings upgraded Brazil’s long-term issuer and senior unsecured bond ratings to “Ba1” from “Ba2.” In May 2025, Moody’s affirmed the Ba1 rating but revised the outlook from positive to stable due to slower progress in addressing fiscal rigidities and concerns regarding debt affordability. Therefore, Brazil remains rated below investment grade by the three main credit rating agencies. Over the next few years, potential fiscal deterioration, increasing debt levels or weaker policy credibility could result in rating downgrades or negative outlook revisions. Conversely, continued structural and microeconomic reforms, sustained economic growth, and progress in stabilizing fiscal accounts and debt dynamics could support future rating upgrades. Brazil continues to experience political instability, which may adversely affect the Company. Brazil’s political environment has historically influenced, and continues to influence, the performance of the country’s economy. Political crises have affected and continue to affect the confidence of investors and the public, which have historically resulted in economic deceleration and heightened volatility in the securities issued by Brazilian companies. Recent developments underscore the persistence of political instability in Brazil. The lead-up to the 2026 presidential elections has been marked by heightened polarization, frequent disputes between different branches of government, and uncertainty regarding the direction of future economic and industrial policies. These dynamics may affect regulatory frameworks, trade relations, and infrastructure investments that are critical to the steel industry. In particular, changes in government priorities or delays in policy implementation could impact demand for steel in construction and manufacturing, as well as alter the competitive landscape through adjustments in taxation, environmental regulation, or labor policies. Such instability may reduce investor confidence, increase market volatility, and adversely affect the Company’s operations and financial performance. In addition, the Brazilian economy remains subject to government policies, which may affect our operations and financial performance. Governmental policies and actions, if unsuccessful or poorly implemented, may affect our operations and financial performance. Uncertainty regarding the implementation by the administration of promised transformational changes in monetary and fiscal policy, as well as the enactment of the corresponding legislation, could contribute to economic instability. 14 Table of Contents Inflation and government actions to combat inflation may contribute significantly to economic uncertainty in Brazil and could adversely affect the Company’s business. If Brazil experiences high levels of inflation once again, the Brazilian Central Bank will need to implement higher interest rate and the country’s rate of economic growth could slow, which would lead to lower demand for the Company’s products in Brazil. Inflation is also likely to increase some costs and expenses which the Company may not be able to pass on to its customers and, as a result, may reduce its profit margins and net income. In addition, higher domestic interest rates, could lead the cost of servicing the Company’s debt denominated in Brazilian reais to increase. Inflation may also hinder its access to capital markets, which could adversely affect its ability to refinance debt. Inflationary pressures may also lead to the imposition of additional government policies to combat inflation that could adversely affect our business. As a result, the Company’s financial condition and results of operations may be adversely affected. Developments and the perception of risks in other countries, especially in the United States and emerging market countries, may adversely affect the market prices of our shares. The market for securities issued by Brazilian companies is influenced, in some degree, by economic and market conditions in the United States and emerging market countries, especially other Latin American countries. The reaction of investors to economic developments in one country may cause the capital markets in other countries to fluctuate. Developments or adverse economic conditions in other emerging market countries have at times resulted in significant reductions of the investments from investment funds and declines in the amount of foreign currency invested in Brazil. The Brazilian economy is also affected by international economic and market conditions, especially economic and market conditions in the United States. Share prices on the B3, for example, have historically been sensitive to fluctuations in United States interest rates as well as movements of the major United States stocks indexes. Economic developments in other countries and securities markets could adversely affect the market prices of our shares, which could make it more difficult for us to access the capital markets and finance our operations in the future on acceptable terms, besides having a material adverse effect on our financial condition and results of operations. Risks Related to our Corporate Structure The interests of the controlling shareholder may conflict with the interests of the non-controlling shareholders. Subject to the provisions of the Company’s Bylaws, the controlling shareholder has powers to: ● elect a majority of the directors and nominate executive officers, establish the administrative policy and exercise full control of the Company´s management; ● sell or otherwise transfer the Company´s shares; and ● approve any action requiring the approval of shareholders representing a majority of the outstanding capital stock, including corporate reorganization, acquisition and sale of assets, and payment of any future dividends. By having such power, the controlling shareholder can make decisions that may conflict with the interest of the Company and other shareholders, which could adversely affect the financial condition and the results of operations of the Company. Nonetheless, it should be noted that the controlling shareholder has responsibilities under the Brazilian Corporations Law (Law No. 6,404/76, which impose a duty to prevent the adoption of decisions that may lead in this direction, and such conflict-of-interest matters are also addressed in the Company’s Related Parties Policy. 15 Table of Contents The loss of members of the senior management and executives of the Company can have an adverse impact on the business. Gerdau has various programs to attract, incentive and retain its senior management and executives, backed up by an inclusive and diverse culture. The Company also carries out evaluations of performance, potential and readiness for advancement to senior management and executives. Gerdau’s ability to remain competitive depends to a large degree on the continuity of efforts and services rendered by its senior management and executives. The loss of members of the senior management and executives can impact the Company’s business, since it can negatively affect our capacity to develop and implement our strategy, adversely impacting our operations and our financial and operating condition, possibly impacting investors’ investment decisions. Some senior management and executives have left Gerdau in the past and others may do so in the future, such that we cannot predict the impact of the departure of senior management or executives or the consequences on the achievement of our business objectives. As a foreign issuer, we have different disclosure and other requirements than U.S. domestic registrants. As a foreign issuer, we may be subject to different disclosure and other requirements than domestic U.S. registrants. For example, as a foreign issuer, in the United States, we are not subject to the same disclosure requirements as a domestic U.S. registrant under the United States Securities Exchange Act of 1934, as amended (the “Exchange Act”), including the requirements to prepare and issue quarterly reports on Form 10-Q or to file current reports on Form 8-K upon the occurrence of specified significant events, the proxy rules applicable to domestic U.S. registrants under Section 14 of the Exchange Act or the insider reporting and short-swing profit rules applicable to domestic U.S. registrants under Section 16 of the Exchange Act. In addition, we intend to rely on exemptions from certain U.S. rules that will permit us to follow Brazilian legal requirements rather than certain requirements that are applicable to U.S. domestic registrants. Furthermore, foreign issuers are required to file their annual report on Form 20-F within 120 days after the end of each fiscal year, while U.S. domestic issuers that are accelerated filers are required to file their annual report on Form 10-K within 75 days after the end of each fiscal year. As a result of the above, even though the Company must file reports on Form 6-K disclosing the information that it has made or is required to make public pursuant to Brazilian law, or is required to distribute to shareholders generally, and that is material to the Company, the investors may not receive information of the same type or amount that is required to be disclosed to shareholders of a U.S. company. As a foreign issuer, we are permitted to, and we do, rely on exemptions from certain NYSE corporate governance standards, including the requirement that a majority of our board of directors consist of independent directors. This may afford less protection to our shareholders. The NYSE’s rules require listed companies to have, among other things, a majority of their board members be independent and to have independent director oversight of executive compensation, nomination of directors and corporate governance matters. As a foreign issuer and a subsidiary, we are permitted to, and we do, follow home country practice in lieu of the above requirements. Brazilian law, the law of our home country, does not require that a majority of our board consist of independent directors or the implementation of a compensation committee or nominating a corporate governance committee, and our board includes fewer independent directors than would be required if we were subject to the NYSE rules applicable to most U.S. companies. As long as we rely on the foreign issuer exemptions to the NYSE rules, a majority of our board of directors is not required to consist of independent directors, our compensation committee is not required to be comprised entirely of independent directors, and we are not required to have a nominating and corporate governance committee. Therefore, our board’s approach may be different from that of a board with a majority of independent directors, and, as a result, the management team’s oversight of the Company may be more limited than if we were subject to the NYSE rules applicable to most U.S. companies. Risks Relating to Our Preferred Shares and ADSs If we do not maintain a registration statement and no exemption from the Securities Act registration is available, U.S. Holders of ADSs may be unable to exercise preemptive rights with respect to our Preferred Shares. We may not be able to offer our Preferred Shares to U.S. holders of ADSs residing in the U.S. pursuant to preemptive rights granted to holders of our Preferred Shares in connection with any future issuance of our Preferred Shares unless a registration statement under the Securities Act is effective with respect to such Preferred Shares and preemptive rights, or an exemption from the registration requirements of the Securities Act is available. We are not obligated to file or maintain a registration statement relating to any preemptive rights offerings with respect to our Preferred Shares, and we cannot assure you that we will file or maintain any such registration statement. If such a registration statement is not filed and maintained and an exemption from registration does not exist, our depositary will attempt to sell the preemptive rights, and you will be entitled to receive the proceeds of such sale. However, these preemptive rights will expire if the depositary does not sell them, and U.S. holders of ADSs will not realize any value from the granting of such preemptive rights. 16 Table of Contents Judgments of Brazilian courts with respect to our Preferred Shares will be payable only in reais. If proceedings are brought in the courts of Brazil seeking to enforce our obligations in respect of the Preferred Shares, we will not be required to discharge our obligations in a currency other than reais. Under Brazilian exchange control limitations, an obligation in Brazil to pay amounts denominated in a currency other than reais may only be satisfied in Brazilian currency at the exchange rate, as determined by the Central Bank, in effect on the date the judgment is obtained, and such amounts are then adjusted to reflect exchange rate variations through the effective payment date. The then prevailing exchange rate may not afford non-Brazilian investors with full compensation for any claim arising out of, or related to, our obligations under the Preferred Shares or the ADSs. If an ADS holder surrenders its ADSs and withdraws Preferred Shares, it risks losing the ability to remit foreign currency abroad and certain Brazilian tax advantages. An ADS holder benefits from the electronic certificate of foreign capital registration obtained by the custodian for our Preferred Shares underlying the ADSs in Brazil, which permits the custodian to convert dividends and other distributions with respect to the Preferred Shares into non-Brazilian currency and remit the proceeds abroad. If an ADS holder surrenders its ADSs and withdraws Preferred Shares, it will be entitled to continue to rely on the custodian’s electronic certificate of foreign capital registration for only five business days from the date of withdrawal. Thereafter, upon the disposition of or distributions relating to, the Preferred Shares unless it obtains its own electronic certificate of foreign capital registration or qualifies under Brazilian foreign investment regulations that entitle some foreign investors to buy and sell shares on Brazilian stock exchanges without obtaining separate electronic certificates of foreign capital registration, such former holder of ADSs would not be able to remit abroad non-Brazilian currency. In addition, if an ADS holder does not qualify under the foreign investment regulations, it will generally be subject to less favorable tax treatment of dividends and distributions on, and the proceeds from any sale of, our Preferred Shares. If an ADS holder attempts to obtain its own electronic certificate of foreign capital registration, it may incur expenses or suffer delays in the application process, which could delay its ability to receive dividends or distributions relating to our Preferred Shares or the return of its capital in a timely manner. The depositary’s electronic certificate of foreign capital registration may also be adversely affected by future legislative changes.

A.HISTORY AND DEVELOPMENT OF THE COMPANY Gerdau S.A. is a Brazilian corporation (Sociedade Anônima) that was incorporated on November 20, 1961, under the laws of Brazil. Its main registered office is located at Av. Dra. Ruth Cardoso, 8501 – 8th floor, São Paulo, SP, Brazil, and the telephone number is +55 (11) 3094 6300. Gerdau’s shares are listed on the São Paulo (B3) and New York (NYSE) stock exchanges. Recent History The Company is the product of several corporate acquisitions, mergers and other transactions dating back to 1901. The Company began operating in 1901 as the Pontas de Paris nail factory controlled by the Gerdau family based in Porto Alegre, who is still the Company’s indirect controlling shareholder. In 1969, Pontas de Paris was renamed Metalúrgica Gerdau S.A., which today is the holding company controlled by the Gerdau family and the parent company of Gerdau S.A. A detailed chronology of the development of the Company from its founding is set forth in our Annual Report on Form 20-F for the year ended December 31, 2020 (File Nº 001-14878), “Item 4A. History and Development of the Company”, which is not incorporated by reference into this Annual Report. Gerdau is the largest Brazilian producer of steel, a leading producer of long steel in the Americas and one of the world’s leading suppliers of special steel. In Brazil, it also produces flat steel and iron ore for its own consumption. Gerdau is the largest recycling company in Latin America and uses scrap as a key input, with around 70% of its steel production derived from this material. Every year, Gerdau transforms about 10 million tonnes of scrap into a variety of steel products. 17 Table of Contents B. BUSINESS OVERVIEW Steel Industry The world steel industry is composed of hundreds of steel producing facilities and is divided into two major categories based on the production method utilized: integrated steel mills and non-integrated steel mills, sometimes referred to as “mini mills.” Integrated steel mills normally produce steel from iron oxide, which is extracted from iron ore melted in blast furnaces, and refine the iron into steel, mainly using basic oxygen furnaces or, more rarely, electric arc furnaces. Non-integrated steel mills produce steel by melting in electric arc furnaces scrap steel, which occasionally is complemented by other metals such as direct-reduced iron or hot-compressed iron. According to World Steel, in 2024 (the most recent year for which information is available), 29.3% of the total crude steel production in the world was through electric furnaces (non-integrated process), 70.5% was through basic oxygen furnaces (integrated process) and the remaining 0.3% in other processes. Crude Steel Production by Process in 2024* Crude Steel Production (in million Production by Process (%) Blast Furnace tonnes) Mini mill Integrated World 1,887 29.3 70.5 China 1,005 10.2 89.8 India 149 58.8 41.2 Japan 84 26.2 73.8 U.S.A. 79 71.6 28.4 Russia 71 32.6 65.2 S.

Over the past 10 years, according to World Steel, total annual crude steel production has grown from 1,676 million tonnes in 2014 to 1,887 million tonnes in 2024, an increase of 12.6%. The main factor responsible for the increase in the demand for steel products has been China. Since 1993, China has become the world’s largest steel market and currently consumes more than half as much as the rest of the world. 18 Table of Contents Crude Steel Production (in million tonnes) * Source: World Steel / Steel Statistical Yearbook 2025 *Most recent year for which information is available China continues to rebalance its economy toward a more consumption-driven growth model. GDP growth was broadly aligned with government expectations, and despite continued credit injections into the construction and infrastructure sectors, steel consumption declined for the fourth consecutive year. In 2024, China’s share of world steel production was 53% of world total crude steel. Crude Steel Production by Country in 2024 (million tonnes) * Source: World Steel / Steel Statistical Yearbook 2025 *Most recent year for which information is available 19 Table of Contents The Brazilian Steel Industry According to World Steel Association, in 2025 Brazil was the world’s 9th largest producer of crude steel, with a production of 33.3 million tonnes, a 1.8% share of the world market. In South America, Brazil represented approximately 80.2% of the total steel production in 2025. According to Instituto Aço Brasil, in 2025 the total of Brazilian steel products sales was 31.9 million tonnes. The breakdown of total sales was 67.1% or 21.4 million tonnes of flat steel products, formed by domestic sales of 12.4 million tonnes and exports of 8.9 million tonnes. The remaining 32.9% or 10.5 million tonnes represented sales of long steel products, which consisted of domestic sales of 8.8 million tonnes and exports of 1.7 million tonnes. Breakdown of Total Sales of Brazilian Steel Products (million tonnes) Source: Instituto Aço Brasil Domestic demand — Historically, the Brazilian steel industry has been affected by significant variations in domestic steel demand. Although domestic consumption varies in accordance with Gross Domestic Product (GDP), variations in steel consumption tend to be more accentuated than changes in the level of economic growth. In 2025, the Brazilian GDP increase was 2.3%, while steel consumption grew by 2.6%. Exports and imports — Over the past 20 years, the Brazilian steel industry has been characterized by a structural need for exports. The Brazilian steel market has undergone periods of excess capacity, cyclical demand and intense competition in recent years. Demand for finished steel products has lagged the total supply (total production plus imports). In 2025, Brazilian steel exports totaled 10.7 million tonnes, representing 33.5% of total sales (domestic sales plus exports). Brazil has performed an important role in the steel export market, mainly as a supplier of semi-finished products (slabs, blooms and billets) for industrial use or for re-rolling into finished products. Brazilian exports of semi-finished products totaled 8.5 million tonnes in 2025, 8.9 million tonnes in 2024 and 9.3 million tonnes in 2023, representing 80.0%, 81.9% and 80.1% of Brazil’s total exports of steel products, respectively. Brazil was the second largest exporter of steel to the United States in 2025. In 2025, when the quota for Brazilian products under Section 232 ended, exports to the U.S. were no longer subject to quantitative restrictions, and importers began paying the 25% tariff, consistent with other exporting countries. As a result, exports to the U.S. in 2025 were 7.7% higher over 2024. However, prices declined by 16% compared to 2024 for Brazilian slabs, reflecting direct competition with lower-priced products of Asian origin. 20 Table of Contents Brazilian Production and Apparent Demand for Steel Products (million tonnes) Source: Instituto Aço Brasil Raw materials — One of Brazil’s major competitive advantages is the low cost of its raw materials. Brazil has an abundance of high-quality iron ore. Various integrated producers are in the state of Minas Gerais, where some of the world’s biggest iron ore mines are located. The cost of iron ore from small miners in Brazil is very competitive if compared to the cost of iron ore in China, for example. In Brazil, most of the scrap metal consumed by steel mills comes from Brazil’s southeast and south regions. Mill suppliers deliver scrap metal obtained from obsolete products and industrial scrap directly to the steel mills. Brazil is a major producer of pig iron. Most of the pig iron used in the steel industry comes from the state of Minas Gerais and the Carajás region, where it is produced by various small and midsized producers. The price of pig iron follows domestic and international markets, with charcoal and iron ore the main components of its cost formation. North American Steel Industry According to World Steel Association, in 2025 U.S. was the 3rd largest global steel producer (4th in 2024), with 81.9 million metric tons. Mexico holds the 15th position, contributing 13.5 million metric tons. Canada has the 17th spot, manufacturing 11.5 million metric tons. 21 Table of Contents Crude Steel Production by North American Countries (million tonnes)* Source: World Steel / Steel Statistical Yearbook 2025 *Most recent year for which information is available The North American steel market is mature and well established, demand fluctuates within a stable band, and its level of activity is directly influenced by general economic conditions, steel import levels, and the strength of the U.S. dollar. Traditionally, the North American market has been a target for steel imports with global origins. The imported steel material was often priced at low levels, sometimes even below production and shipping costs. In response to these import practices, the U.S. supported the domestic industry through Section 232 tariffs—initially set at 25% in March 2018 for national security reasons. Over time, these were largely replaced by bilateral agreements: Australia was exempted, while South Korea, Brazil, and Argentina negotiated hard-cap quotas. By 2019, tariffs were removed for Canada and Mexico in favor of volume monitoring. Additionally, Section 301 tariffs targeting Chinese steel were established in 2018 and maintained through the Biden administration. In 2022, the 25% tariffs for the EU, UK, and Japan were transitioned into tariff-rate quotas, which defined the trade landscape until the recent universal reinstatements. On February 18, 2025, a proclamation was issued announcing the termination of existing 232 exception agreements with several countries, including Canada, Mexico, the European Union, Japan, South Korea, the United Kingdom, Argentina, Australia, and Brazil. The document underscored national security concerns regarding the surge in steel imports, which adversely affected U.S. domestic production driving the steel industry’s capacity utilization below the critical 80% level, necessary for sustaining production capabilities for national security. Additionally, the measure aimed at addressing transshipment and further processing of steel from restricted countries, such as China, through Mexico and other exempted nations. Imports from Ukraine, previously exempted, are also now subject to tariffs, as the exemption was found to primarily benefit EU producers rather than Ukraine. Furthermore, certain derivative steel products not originally covered by the 2018 tariffs are now subject to the 25% duty. The previous system allowing U.S. importers to request exemptions for specific steel products was also terminated, with no further exclusions permitted to prevent loopholes that could undermine the tariffs’ intended objectives. In June 2025, President Trump announced that Section 232 steel tariffs were being increased to 50% (with the exception of the UK, which remained at 25%). Finally, the shift in U.S. trade policy is still developing, and therefore there are no assurances that the reimposed 50% tariffs expected to favor the domestic steel production will not be lifted, altered, or significantly weakened – whether by legal challenges, new legislation, additional executive actions, or other means – it is likely that foreign steel imports will rise, leading to a decrease in U.S. steel prices. This change could have a significant negative impact on our revenues, financial performance, and cash flow. Company Profile Gerdau S.A. is mainly dedicated to the production and commercialization of steel products in general, through its mills located in Brazil, Canada, the United States, Argentina, Peru, Uruguay and Mexico (joint venture). 22 Table of Contents Gerdau is the leading manufacturer of long steel in North and South America. Gerdau believes it is one of the major global suppliers of special steel for the automotive industry. In Brazil, Gerdau also produces flat steel and iron ore for internal consumption, activities that are expanding Gerdau’s product mix and the competitiveness of its operations. In addition, Gerdau believes it is one of Latin America’s biggest recyclers and, worldwide, transforms millions of tonnes of scrap metal into steel every year, reinforcing its commitment to sustainable development in the regions where it operates. Gerdau’s shares are listed on the New York and São Paulo stock exchanges. Gerdau holds significant market share in the steel industries of almost all countries where it operates and was classified by World Steel Association as the world’s 33rd largest steel producer based on its consolidated crude steel production in 2024, the most recent year for which information is available. Gerdau operates steel mills that produce steel in blast furnaces and in electric arc furnaces (EAF). In Brazil it operates three integrated steel mills, including its largest mill, Ouro Branco, located in the state of Minas Gerais. Gerdau currently has a total of 29 steel producing facilities globally. As of December 31, 2025, Gerdau’s total consolidated installed annual capacity, excluding investments in joint ventures and associate companies, was approximately 15.7 million tonnes of crude steel and 15.0 million tonnes of rolled steel products. The Company had total consolidated assets of R$ 81.7 billion, shareholders’ equity (including non-controlling interests) of R$ 53.8 billion, consolidated net sales of R$ 69.9 billion and total consolidated net income (including non-controlling interests) of R$ 1.4 billion for the year ended December 31, 2025. Its product mix includes crude steel (slabs, blooms and billets), which is sold to rolling plants; finished products for the construction industry, such as rebar, wire-rods, structural shapes, hot-rolled coils and heavy plates; finished industrial products, such as commercial rolled-steel bars, light profiles and wires; and agricultural products, such as stakes, smooth wire and barbed-wire. Gerdau also produces special steel items using cutting-edge technology. The Company currently operates 10 steel production units (including special steels units) in the United States and 3 steel production units in Canada and believes it is one of the leading companies in North America in the production of certain long steel products, such as rebar, merchant bars and beams. The Company’s operating strategy is based on the acquisition and construction of steel mills located near its clients and the sources of the raw materials needed to make steel, such as scrap steel, pig iron and iron ore. Therefore, historically, most of production has been directed to supply the local markets of the regions where the Company operates. However, the Company also exports an excess portion of its production to other countries. Through its subsidiaries and associate companies, the Company also engages in other activities related to the production and sale of steel products, including reforestation projects; electric power generation projects; production of iron ore and pig iron; as well as fab shops and downstream operations. Operations The Company sells its products to a diversified list of customers for use in the construction, manufacturing and agricultural industries. Shipments by the Company’s Brazilian operations include both domestic and export sales. Most of the shipments by the Company’s business segments in North and Latin America (except Brazil) are aimed at their respective local markets. Starting with the disclosure of the results of 2025, the Company began to disclose the information and results of its business segments as follows: ● Brazil Segment*: includes the long, flat and special steel operations and the iron ore operation located in Brazil and joint ventures and associated companies located in Brazil; ● North America Segment: includes the long and specialty steel operations located in Canada and the United States and the joint ventures located in Canada and Mexico; ● South America Segment**: includes the operations in Argentina, Peru and Uruguay. 23 Table of Contents With these changes, the information and results of the former Special Steel Segment, which included the special steel operations located in Brazil and the United States, are now disclosed jointly with the other segments, according to their geographic location, as the Brazil Segment and the North America Segment, respectively. This new format for disclosing information and results is in line with recent changes in the global steel industry scenario, which have led to an increasing regionalization of markets, business dynamics and local currencies of these operations, improving the presentation of Gerdau’s results in Brazil and North America, the main regions in which it operates. The comparative information of the segments presented in these Financial Statements has been adjusted to reflect this new composition. *On February 10, 2025, the Company, after fulfilling all the conditions precedent, including approval by the antitrust authorities, concluded the transaction with Sumitomo Corporation and The Japan Steel Works Ltd., for the acquisition of 39.53% and 1.74%, respectively, of the total shares issued by Gerdau Summit Aços Fundidos e Forjados S.A. (“Gerdau Summit”). With the closing of the transaction, the Company will own 100% of the Gerdau Summit’s capital Gerdau Summit, until then a joint venture, with this transaction becomes a subsidiary of the Company. **In January 2024, Gerdau announced the sale of its stake in joint ventures Diaco S.A. and Gerdau Metaldom Corp. and their subsidiaries, which were part of the South America Business Segment. The following tables present the Company’s consolidated shipments in tonnage, net sales, and production by Business Segment for the periods indicated: Shipments Gerdau S.A.

This Business Segment minimizes delays by delivering its products directly to customers through outsourced companies under Gerdau’s supervision. Sales trends in both the domestic and export markets are forecasted monthly. The Brazil Business Segment uses a proprietary information system to stay up to date on market developments so that it can respond swiftly to fluctuations in demand. Gerdau considers its flexibility in shifting between markets (Brazilian and export markets) and its ability to monitor and optimize inventory levels for most of its products in accordance with changing demand as key factors to its success. In 2025, crude steel production decreased 2.9% compared to 2024, reflecting the fierce competitive local environment, notably due to the growing share of imported steel and new capacity entrants in Brazil. The Company directed 78.1% of its shipments in the Brazil Business Segment to the domestic market in 2025, which represents -3.2 p.p versus 2024. However, its domestic market volumes remained impacted by the excessive importation of steel into the country in 2025, creating a predatory competition dynamic with the local industry. On the other side, even with steel tariff escalation abroad, Brazil Business Segment exports grew 21% in volume versus 2024 and contributed to the dilution of fixed costs and operational leverage for the period, representing 21.9% of Gerdau’s shipments. Despite the resilience of the construction sector, in both the retail segment and direct sales to contractors, industries like manufacturing showed mixed results with gains in light vehicles and declines in sectors like heavy trucks, road transport equipment and white goods. Gerdau’s mineral assets were incorporated to its business through the acquisition of lands and mining rights of Grupo Votorantim, in 2004, encompassing the Miguel Burnier, Várzea do Lopes, and Gongo Soco compounds, located in the iron producing region in the state of Minas Gerais, Brazil. From 2004 to 2019, several geological surveys (drilling and superficial geological mapping) were conducted to obtain further information on the acquired resources. As part of that undertaking, in 2023 Gerdau received a report prepared by SRK Consulting, certifying the reserves of Miguel Burnier mine. According to the conclusions of the report, the Company now holds certified reserves of 476 million metric tonnes (Dry metric tonnes) of iron ore. For more information, see Item 3.D –“Risk Factors ⸺ Risks Relating to our Mining Operations ⸺ Estimates of Gerdau’s mineral resources are based on interpretations and assumptions, involving a level of uncertainty, and may differ substantially from the quantities that can be extracted.” North America Business Segment The North America Business Segment has annual production capacity of approximately 6.9 million tonnes of crude steel and 6.0 million tonnes of finished steel products. It has a vertically integrated network of 10 steel units, scrap recycling facilities and downstream operations. The North America Business Segment’s products are generally sold to steel service centers, steel fabricators or directly to original equipment manufacturers for use in a variety of industries, including construction, automotive, mining, energy, cellular and electrical transmission, metal construction fabrication, and equipment fabrication. Most of the raw material feed stock for the mini mill operations is recycled steel scrap. The mills of this business operation manufacture and commercialize a wide range of steel products, including steel reinforcement bars (rebar), merchant bars, structural shapes, beams, piling, and special sections. Some of these products are used by the downstream units to make products with higher value-added, which consists of railroad spikes, super light beam processing, elevator guide rails, grinding balls and solar piles. Sales of finished products to U.S. and Canadian customers are centrally managed by the sales office in Tampa, Florida. There is also a sales office in Selkirk, Manitoba for managing sales of special sections and one in Midlothian, Texas for managing sales of structural and merchant bar products. Metallurgical service representatives at the mills provide technical support to the sales group. Sales of the super light beam products are managed by sales representatives located at their respective facilities. Elevator guide rails are generally sold through a bidding process in which employees at Gerdau’s facilities work closely with customers to tailor product requirements, shipping schedules and prices. 25 Table of Contents In 2025, crude steel production and steel shipments in North America were 11.5% and 9.4% higher than in 2024, respectively, evidencing not only the improved momentum of the local industry, driven by declining imports following the reinforcement of tariffs, but also the enhancement of position in key markets and the growing share of higher value-added products and solutions. Steel shipments in 2025 were positively impacted by a strong customer preference for domestic steel, and by increasing demand from end-market sectors such as Data Centers and Renewable Energy. South America Business Segment The South America Business Segment comprises 3 steel facilities, retail facilities, fab shops and scrap processing facilities. The entire operation is focused on the respective domestic markets of each country, operating mini mills facilities with annual manufacturing capacity of approximately 900 thousand tonnes of crude steel and 800 thousand tonnes of finished steel products. The countries in the South America Business Segment are Argentina, Peru, and Uruguay. Steel production and shipments in 2025 increased by 5.0% and 10.0%, respectively, compared to 2024 fueled by increased volumes in the three countries where we operate. However, the key sectors served still showed weaker demand throughout the year. In Argentina, civil construction activity levels hit all-time lows, while in Uruguay, infrastructure works remained halted. On the other hand, in Peru, the order backlog remained resilient, driven by demand from the civil construction distribution sector Exports In 2025, the steel industry worldwide faced an increase in trade defense measures against predatory suppliers, as China’s finished steel exports hit an all-time record of 119M mt. More than ever, countries and blocs are trying to protect their local production and industries by promoting a trade war, like the import tariff increase from 25% to 50% made by the current United States government under Section 232. With this scenario, world crude steel production contracted 2% year over year in 2025, according to recently published data from the World Steel Association. Increases in India (10.4%), Vietnam (12.2%), US, Turkey and Italy (~3%) were not enough to offset the decline in China (4.4% YoY,) as well as decreases in the other five of the top 10 steel-producing countries. Also, according to World Steel, demand for steel was set to remain stable at 1,749Mt in 2025, with China accounting for 50.8% of apparent consumption. Gerdau’s focus remains primarily on the Americas, with increased sales to Europe concentrated mainly on higher value-added products. With the end of steel import quotas in the United States, North America’s share grew significantly in the first half of the year compared to the previous period. The table below presents Gerdau’s Brazilian exports by destination for selected periods: Exports of Gerdau by Destination (%) 2025 2024 2023 2022 2021 2020 Total including shipments to subsidiaries (1,000 tonnes) 1,185 966 1,004 928 714 825 Africa 1 % — % — % 4 % — % 2 % Central America 22 % 37 % 43 % 28 % 12 % 21 % North America 24 % 17 % 8 % 4 % 9 % 3 % South America 41 % 42 % 44 % 56 % 61 % 54 % Asia 2 % — % — % 5 % 17 % 17 % Europe 10 % 4 % 5 % 23 % 1 % 3 % Middle East — % — % — % — % — % — % The company remains focused on serving strategic markets that contribute to the overall performance of its operations, continuously assessing the impacts and opportunities arising from the persistent volatility of the international political and economic environment. 26 Table of Contents Products The Company supplies its customers with a wide range of products, including steel products: Semi-finished products (Billets, Blooms and Slabs) The semi-finished products (billets, blooms and slabs) have relatively low added value compared to other steel products. Billets are bars from square sections of long steel that serve as inputs to produce wire rod, rebars and merchant bars. They represent an important part of the products from the Ouro Branco mill. Blooms are used to manufacture products such as springs, forged parts, heavy structural shapes and seamless tubes. Slabs are used in the steel industry for the rolling of a broad range of flat rolled products and mainly used to produce hot and cold rolled coils, heavy slabs, profiles and heavy plates. The semi-finished products are produced using continuous casting and, in the case of blooms and billets there is subsequent rolling process. Common Long Rolled Products Common long rolled products represent a major portion of the Company’s production. The Company’s main long rolled products include rebars, wire rods, merchant bars, light shapes and profiles, which are used mainly by the construction and manufacturing industries. Drawn Products Drawn products include barbed and barbless fence wire, galvanized wire, fences, concrete reinforcing wire mesh, nails and clamps. These products are not exported and are usually sold to the manufacturing, construction and agricultural industries. Special Steel Products Special steel requires advanced manufacturing processes because they have specific physical and metallurgical characteristics for applications with high mechanical demands. This steel is a key product for the automotive industry, as it is used in auto parts, light and heavy vehicles and agricultural machinery. Special steels also serve other significant markets, such as oil and gas, wind energy, machinery and equipment, mining and rail, among others. Flat Products The Ouro Branco unit produces cast slabs, which are rolled into flat products, such as hot-rolled coils, which are sold in the domestic market, and heavy plates, which are sold in the domestic and export markets. The Company, through its distribution channel and direct sales, distributes these hot-rolled coils and heavy plates, which adds more value through additional processing at flat steel service centers. Iron Ore Gerdau has two mines producing iron ore, all located in the Brazilian state of Minas Gerais (Várzea do Lopes and Miguel Burnier). The mines produce the following: sinter feed (featuring low content of contaminants and good metallurgical properties, enabling its use as a base material); pellet feed/concentrated (superior quality enabling its use as a chemical balancer in the synthetizing process, while also adequate for pelletizing, blast furnace quality - low loss by calcination — PPC); hematite fines (small scale production, used as input in Gerdau’s furnaces); used chiefly for own consumption at the Ouro Branco Mill). 27 Table of Contents The following table presents the main products and the contributions to net revenue and net income by Business Segment for the periods shown (consolidated): Brazil North America South America Eliminations and Adjustments Rebars, merchant bars, beams, drawn products, billets, blooms, slabs, wire rod, structural shapes, hot rolled coil, Rebars, merchant bars, wire rod, light Rebar, merchant bars and Products heavy plate and iron ore. and heavy structural shapes. drawn products.

In general, the Company has used the mini mill model to produce steel products outside of Brazil. Semi-integrated Process (Mini-mills) The Company operates 27 mini-mills worldwide, 11 located in Brazil, 13 in North America and 3 in South America. Mini-mills recycle steel scrap and are equipped primarily with electric arc furnaces that can melt steel scrap and produce steel products at the required specifications requested by customers. After loading the furnace with a preset mixture of raw material (i.e., steel scrap), electric power is applied in accordance with a computer-controlled melting profile. The Company’s mini mill production process generally consists of the following steps: obtaining raw material (steel scrap), melting, casting, rolling, and drawing. The basic difference between this process and the integrated mill production process described below is in the first processing phase, i.e., the steelmaking process. Mini mills are smaller plants than integrated facilities and the Company believes they provide certain advantages over integrated mills, including: ● Be a recycling process; ● Lower greenhouse gas emissions; ● Lower capital costs; ● Lower operational risks due to the low concentration of capital and installed capacity in a single production plant; ● Proximity of production facilities to raw-material sources; ● Proximity to local markets and easier adjustment of production levels; and ● More effective managerial structure due to the relative simplicity of the production process. Integrated Process Integrated mills produce steel from iron ore and are equipped primarily with blast furnaces that can transform iron ore into metallic iron. Gerdau operates three integrated mills located in Brazil. The Ouro Branco Mill is the largest integrated facility operated by the Company. It produces steel from pig iron from the blast furnace and has some of the advantages of a mini mill, since it is located near Gerdau’s iron ore source and linked by railways to Gerdau’s ports from which Gerdau exports part of its production. The Divinópolis Mill is the other integrated facility operated by the Company and produces steel using charcoal instead of mineral coal to transform iron ore into metallic iron. This route is considered low greenhouse emission since charcoal is sustainably produced at Gerdau’s farms. The third mill, Barão de Cocais, suspended production in 2024 due to the tougher domestic market in Brazil. 28 Table of Contents Gerdau’s steel manufacturing process at integrated units consists of four basic stages: preparation of raw materials, production of pig iron, production of steel, and production of semi-finished steel products (billets, blooms, and slabs). In the first stage, sinter (a mixture of iron ore and limestone), coke, and other raw materials are consumed in the Ouro Branco unit blast furnace to produce pig iron, while charcoal and other raw materials are consumed at the Divinópolis unit. Coke and charcoal act as both fuel and a reducing agent, transforming the oxide called iron ore into metallic iron. Gerdau’s blast furnaces have an aggregate installed capacity of approximately 4.1 million tonnes of molten pig iron per year. The pig iron produced is transported by rail to the desulphurization unit to reduce the steel’s sulfur content. After the desulphurization process, the low-sulfur pig iron is transformed into steel using LD-type oxygen converters. The LD steelmaking process utilizes molten pig iron and scrap to produce steel by blowing oxygen over the metallic charge inside the converters. The process does not require any external source of energy, which is fully supplied by the chemical reactions occurring between oxygen and the impurities in the molten pig iron. The LD steelmaking process is currently the most widely used in the world. There is also secondary refining after the LD converters’ output with ladle furnaces and degassing processes. Liquid steel is then sent to the continuous casting equipment, where it is solidified into billets, blooms, or slabs. These products may be sold to clients directly, transferred to other Gerdau units for transformation, or used in the production of finished rolled steel products at the integrated units. Gerdau’s integrated units in Brazil have rolling mills for rebars, bars and profiles, wire rod, structural shapes, hot-rolled coils, and heavy plates. Logistics Gerdau sells its products through a combination of independent distributors, direct sales from the mills and its retail network. Logistics costs are an important component in the steel businesses and are a significant factor in maintaining competitive prices in both domestic and export markets. Gerdau’s mills are strategically located in different geographic regions, allowing the Company to gain a competitive advantage. The proximity of these mills to raw material sources and important consumer markets helps reduce costs in obtaining raw material and enhances customer service. This logical efficiency is a significant advantage for both inbound and outbound operations. To monitor and reduce logistic costs, Gerdau employs tailored solutions for various transportation modes, including road, rail, sea and cabotage, as well for terminals, technology and equipment. Gerdau stands out as one of the Brazilian industries with the greatest participation in multimodal transportation, aligned with our effort to reducing our carbon footprint. The Company is committed to continuously improving its performance by receiving raw materials and delivering products to its customers of designated ports. As part of this effort, Gerdau develops and maintains long-term relationships with logistic suppliers specializing in delivering raw materials and steel products. In 1996, Gerdau acquired an interest in MRS Logística, one of the most important rail companies in Brazil, which operates connecting the states of São Paulo, Rio de Janeiro and Minas Gerais, which are Brazil’s main economic centers, and also reaches the main ports of the country in this region. This interest assures the availability of this mode to transport raw materials (scrap and pig iron) as well as final products. Gerdau uses a variety of ports to deliver products from the entire Brazilian coastline. Most exports are shipped from the Praia Mole Private Steel Terminal in Vitoria, Espírito Santo. Overseas, Gerdau owns a private port terminal in Chimbote (Peru), where the Company has a steel mill, used to deliver inputs, raw material and products for the operation. 29 Table of Contents Competition The steel market is divided into manufacturers of long steel products, flat steel products and special steel. The Company operates in the long steel market, which is the most important market for Gerdau, by supplying to the following customer segments: (i) construction, to which it supplies rebars, merchant bars, sections, beams, nails and meshes; (ii) manufacturing, to which it supplies products for machinery, agricultural equipment, tools and other industrial products; and (iii) other markets, to which it supplies wires and posts for agricultural installations and reforestation projects. In North America, the Company also supplies customers with special sections, including elevator guide rails and super light beams. The Company also provides its customers with higher value - added products at rebar and wire rod fabrication facilities. The Company operates in the flat steel market only in Brazil through the Ouro Branco mill that produces slabs, which are used to roll flat products such as hot-rolled coils and heavy plates. The Company distributes these hot-rolled coils to which it adds further value through additional processing at its flat steel service centers. The Company produces special and stainless steel used in tools and machinery, chains, fasteners, railroad spikes, special coil steel, grader blades, smelter bars, light rails, super light I-beams, elevator guide rails and other products that are made on demand for the Company’s customers at its special steel units in Brazil and United States. Competitive Position — Brazil The Brazilian steel market is very competitive. In the year ended December 31, 2024 (most recent information), ArcelorMittal Brasil and the Company were the two largest Brazilian crude steel producers, according to the Brazilian Steel Institute (IABr - Instituto Aço Brasil). World common long rolled steel demand is met principally by steel mini mills and, to a much lesser extent, by integrated steel producers. In the Brazilian market, no single company competes against the Company across its entire product range. The Company believes that the diversification of its products, the solution developed by its fab shops units and the decentralization of its business provide a competitive edge over its major local competitors. The main Gerdau competitors in long steel segment are ArcelorMittal, Simec, Sinobrás, Aço Verde do Brasil (AVB) and Companhia Siderúrgica Nacional (CSN). Regarding the flat steel market, Gerdau’s competitors are ArcelorMittal, Usiminas and CSN. Besides the local competitors, the Company has been facing substantial competition from long and flat steel products imports, mainly coming from China. According to the Brazil Steel Institute, the steel import penetration rate in Brazil reached 21% in 2025, 60% above the average of the last ten years, while the import volume in 2025 was 7.4% higher than in 2024, increasing the local competitive imbalance, chiefly due to steel imports under predatory competition conditions. Although the Company is a modern and highly efficient producer, it cannot compete with heavily subsidized imports, which directly affect the competitiveness of its industry. Competitive Position — Outside Brazil Gerdau’s geographic market in North America encompasses primarily the United States and Canada. The Company faces substantial competition in the sale of each of its products from numerous competitors in its markets. Rebar, merchant bars and structural shapes are commodity steel products for which pricing is the primary competitive factor. Due to the high cost of freight relative to the value of steel products, competition from non-regional producers is somewhat limited. Proximity of product inventories to customers, combined with competitive freight costs and low-cost manufacturing processes, are key to maintaining margins on rebar and merchant bar products. Rebar deliveries are generally concentrated within a 350-mile radius of the mini mills and merchant bar deliveries are generally concentrated within a 500-mile radius. Some products produced by the Midlothian, Jackson, Cartersville and Petersburg mini mills are shipped greater distances, including overseas. The Company’s principal competitors include Commercial Metals Company (CMC), Nucor Corporation, and Steel Dynamics Inc. 30 Table of Contents In South America, each country has a specific competitive position that depends on conditions in their respective markets. Most compete domestically and face significant competition from imports. More than 90% of shipments from Gerdau’s South American operation originate from Argentina and Peru. In this market, the main barriers faced by Gerdau sales are freight and transportation costs and the availability of imports. The main products sold in the South American market are for the construction, agriculture and mining markets. Despite the large-scale characteristic of rebars, bars and profiles, Gerdau believes that it stands out from many of its competitors for its wide range of products, quality, consistent delivery performance and the ability to fulfill large orders. Gerdau believes that it produces one of the most complete lines of bars and profiles. The variety of products offered by Gerdau is an important competitive advantage in a market where many customers seek to meet their needs with few key suppliers. Business Cyclicality and Seasonality The steel industry is highly cyclical. Consequently, the Company is exposed to fluctuations in the demand for steel goods that in turn cause fluctuations in the prices of these goods. Furthermore, since the production capacity of Brazil’s steel industry exceeds its demand, it is dependent on export markets. The demand for steel goods and consequently the financial conditions and results of operations of steel producers, including the Company, are generally affected by fluctuations in the world economy and in particular the performance of the manufacturing, construction and automotive industries. Unfavorable conditions in China and steel-exporting countries can significantly impact steel prices in other markets. China, as the world’s largest steel producer and consumer, influences global steel demand and supply dynamics. Factors like a lack of real estate investment, lower consumer confidence and rationalization of government stimulus can diminish steel demand within China, affecting global prices. Additionally, steel-exporting countries, benefiting from lower production costs, efficient supply chains, and economies of scale, can exert competitive pressures on international steel prices, particularly when coupled with government subsidies or trade agreements. These combined factors create a complex interplay of supply and demand forces that can swiftly impact steel prices worldwide. In Gerdau’s Brazilian and South American operations, shipments in the second and third quarters of the year tend to be stronger than in the first and fourth quarters, given the seasonality, and reduction of sector’s activity such as construction. In Gerdau’s North American operations, demand is influenced by winter conditions, when consumption of electricity and other energy sources (i.e., natural gas) for heating increases and may be exacerbated by adverse weather conditions, contributing to increased costs and decreased construction activity, and in turn leading to lower shipments. Information on the Extent of the Company’s Dependence The Company is not dependent on industrial, commercial or financial agreements (including agreements with clients and suppliers) or on new production processes that are material to its business or profitability. The Company also has a policy of diversifying its suppliers, which enables it to replace suppliers without affecting its operations in the event of failure to comply with the agreements, except in the case of its energy and natural gas supply. In addition to the government regulations that apply to its industry in general, the Company is not subject to any specific regulations that materially or adversely affect its business. In the case of a power outage, there are no alternative supply options available at most Gerdau mills due to the high volume and tension required for the operation of these plants. Some of Gerdau’s small plants may choose, as an alternative, to use generators to compensate for the energy shortage. Moreover, at the Ouro Branco Mill, about 90% of the thermal demand in stationary equipment such as furnaces, regenerators and boilers is met by gases resulting from the steelmaking process. In case of a lack of natural gas, the equipment could be adjusted to use diesel and LPG. Gerdau’s operations are spread across various geographic regions, which provides a risk diversification of any electricity or natural gas supply problems in Brazil. The distribution of electric power and natural gas is a natural monopoly in most countries, which leads the distributor to be the only supplier in each geographic region. In some countries, regulations allow for a choice of electrical power or natural gas commodity supplier, allowing Gerdau to diversify its supply agreement portfolio. 31 Table of Contents Production Inputs Price volatility Gerdau’s production processes are based mainly on the mini mill concept, with mills equipped with electric arc furnaces that can melt ferrous scrap and produce steel products at the required specifications. The main raw material used at these mills is ferrous scrap, which at some plants is blended with pig iron. The component proportions of this mixture may change in accordance with prices and availability to optimize raw material costs. Iron, iron ore (used in blast furnaces) and ferroalloys are also important. Although international ferrous scrap prices suffer high influence by the U.S. domestic market (since the United States is the largest scrap exporter), the price of ferrous scrap in Brazil varies from region to region and is influenced by supply, demand and transportation costs. Brazil Segment — The Company’s Brazilian mills use scrap and pig iron purchased from local suppliers. Due to the nature of the raw materials used in its processes, Gerdau acquires scrap from the domestic market in accordance with the operational requirements of its mills. Scrap for the Brazilian operation is priced in Brazilian reais; thus input prices are not directly affected by currency fluctuations. Due to its size, the Ouro Branco mill has developed over the last few years a strategy to diversify its raw materials, which are supplied through various types of contracts and from multiple sources, which include: (i) coking coals imported from Colombia, the United States and Russia as well as petroleum coke purchased from Petrobras; (ii) ferroalloys, of which around 90% are purchased in the domestic market; and (iii) iron ore, which is mainly produced from its own mines and partially supplied by mining companies, most of them strategically located close to the plant. North America Business Segment — The main input used by the Company’s mills in North America is ferrous scrap, and it has consistently obtained adequate supplies of raw materials, not depending on a small number of suppliers. Since the United States are one of the largest scrap exporters in the world, the prices of this raw material, in the country, may fluctuate according to domestic supply vs. global demand. In September 2024 Gerdau acquired the assets of Dales Recycling Partnership, a company engaged in the operation, processing, and recycling of ferrous and non-ferrous scrap with an annual capacity to process approximately 160,000 tons of ferrous and non-ferrous scrap. This acquisition aims to increase Gerdau’s captive ferrous scrap in North America through proprietary channels, supplying raw materials at a competitive cost. South America Business Segment — The main input used by the Company’s mills in South America is ferrous scrap. This operation is exposed to market fluctuations, varying its prices according to each local market. Ferrous Scrap There are two broad categories of ferrous scrap: (i) obsolete scrap, which is steel from various sources, ranging from cans to car bodies and white goods; and (ii) industrial scrap, which is composed of scrap from manufacturing processes, essentially steel bushings and flashings, steel turnings and even scrap generated by production processes at steel producers, such as Gerdau. In Brazil, the use of scrap in electric arc furnaces varies between scrap from obsolescence and industrial scrap. Special Steel mills mainly use industrial scrap. Because ferrous scrap is one of its main raw materials in steel production, Gerdau is dedicated to improving its supply chain in various countries, aiming to develop and integrate micro and small suppliers into the Company’s business. In Brazil, the main part of the scrap consumed by the Company comes from small scrap collectors who sell all their material to Gerdau, which provides a direct supply at more competitive costs for the Company. In North America, although the scrap supply is more consolidated, the number of vendors is still significant, ensuring the competitiveness of the business in the region. Brazil Business Segment — The price of steel scrap in Brazil varies by region and reflects local supply, demand and transportation costs. The Southeast is the country’s most industrialized region and generates the highest volume of scrap. Due to the high concentration of players in this region, competition is more intense. In Brazil, Gerdau has five scrap shredders, including mega-shredder at the Cosigua mill in Rio de Janeiro and at the Araçariguama mill in Sao Paulo, with capacity to process scrap in volumes superior to 200 vehicles per hour. The Company will start a new mega shredder at the Pindamonhangaba mill by 2026. 32 Table of Contents North America Business Segment — Ferrous scrap is the main raw material. The availability of this input varies according to the level of economic activity, seasonality, export levels, climatic conditions and price fluctuations. Of the thirteen units in the North America Business Segment, five of them have shredders on-site. Considering that not all the scrap consumed comes from their yards, the rest of the demand is guaranteed through direct acquisitions or via resellers who originate and prepare the scrap. In North America, all production units are semi-integrated mills or mini mills, in which results of operations are closely related to the cost of ferrous scrap and its substitutes, which are the main input of mini mills. Ferrous scrap prices are relatively higher during the winter months in the north hemisphere due to the impact of climate on collection and supply. More than half of North America’s steel industry output is currently produced in electric arc furnaces with the use of ferrous scrap. Prices of ferrous scrap are subject to market forces beyond the Company’s control, including demand from the United States and international steel producers, freight costs and speculation. South America Business Segment — The price of scrap in South America varies widely from country to country in accordance with supply, demand and transportation cost. Pig Iron and Sponge Iron Brazil is an exporter of pig iron. Most of Brazil’s pig iron is produced in the state of Minas Gerais by small producers. Pig iron is an important component of the metallic charge in steelmaking complementing scrap in the mix. The price of pig iron follows domestic and international demand, and its cost production is basically composed by reducers and minerals. In North America, the availability of scrap plays an important role for our operations. Sponge iron and pig iron are used in limited quantities to produce steels with specific characteristics. Iron Ore Iron ore is the main input used to produce pig iron at Gerdau’s blast furnace mills located in the state of Minas Gerais, southeastern Brazil. The pig iron is used in the melt shops together with scrap, to produce steel. Iron ore is purchased in its natural form as lump ore, pellet feed or sinter feed, or agglomerated as pellets. The lump ore and pellets are loaded directly into the blast furnace, while the sinter feed and pellet feed need to be agglomerated in the sinter plant and then loaded into the blast furnace, to produce pig iron. The production of 1.0 tonne of pig iron requires about 1.6 tonnes of iron ore. Iron ore consumption in Gerdau mills in Brazil amounted to 6.3 million tonnes in 2025, partially supplied by mining companies adjacent to the steel plants and partially supplied by Gerdau’s mines. Other Inputs In addition to scrap and iron ore, Gerdau’s operations use other inputs to produce steel such as ferroalloys, electrodes, furnace refracting materials, oxygen, nitrogen, and other industrial gases and limestone, albeit in smaller amounts. Additional inputs associated with the production of pig iron are thermal reducers, such as coal coke, charcoal, or natural gas, which are used in blast furnace mills. The Ouro Branco mill’s significant raw materials and inputs also include solid fuels, comprising metallurgical coal, used in the production of coke and for pulverized injection into the blast furnace. This process increases productivity and consequently reduces the final cost of pig iron. Besides metallurgical coal, the Company also uses anthracite, a solid fuel used in the production of sinter. The gases resulting from the production of coke and pig iron are reused to generate thermal energy, which is converted into electric energy for the mill, improving energy efficiency. 33 Table of Contents The North American operations also use additional inputs. Various domestic and foreign companies supply other important raw materials or operating supplies required for the business, including refractory materials, ferroalloys and graphite electrodes that are available in the national and international market. Gerdau North America Business Segment has obtained adequate quantities of these raw materials and supplies at competitive market prices. The Company is not dependent on any one supplier as a source for any particular material and believes there are adequate alternative suppliers available in the marketplace if the need to replace an existing one arises. Energy Requirements Steel production is a process that consumes large amounts of electricity, especially in electric arc mills. Electricity represents an important role in the production process, along with natural gas, which is used mainly in furnaces to re-heat billets in rolled steel production. In Brazil, electricity is currently supplied to the Company’s industrial units under one type of contracts: ● Contracts executed in the Free Market Environment, in which Gerdau is a “Free Consumer”, are used by the following units: Açonorte, Araçariguama, Araucária, Caucaia, Charqueadas, Cosigua, Cearense, Ouro Branco, Divinópolis, Barão de Cocais, Riograndense, São José dos Campos, Cumbica, Cotia, Pindamonhangaba, Mogi das Cruzes, Várzea do Lopes, Miguel Burnier, São Caetano do Sul, Sete Lagoas and Usiba. The load of these units is served by a portfolio of contracts and by self-generation. The power supply contracts are entered into directly with generation and/or distributing companies at prices that are pre-defined and adjusted in accordance with conditions pre-established by the parties. The transmission and distribution rates are regulated and revised annually by ANEEL (Regulatory agency for the electricity sector in Brazil). In the Ouro Branco mill approximately 25% of the electricity consumed is generated internally. As a result, this makes the plant have significantly lower exposure to the energy market than mini mills. The Company holds the following power generation concession in Brazil: ● Dona Francisca Energética S.A. (DFESA) operates a hydroelectric power plant with nominal capacity of 125 MW located between Nova Palma and Agudo, Rio Grande do Sul State (Brazil). Its corporate purpose is to operate, maintain and maximize use of the energy potential of the Dona Francisca Hydroelectric Plant. DFESA participates in a consortium (Consórcio Dona Francisca) with the power utility Companhia Estadual de Energia Elétrica (CEEE). The shareholders of DFESA are Gerdau S.A. (53.94%), COPEL Participações S.A (23.03%) and Celesc (23.03%). The terms of the Dona Francisca generation concession agreements are for 39 years as of the signature of the agreement. As such: DFESA expires in 2037. ● Gerdau holds a 40% stake in Newave Energia. As a result, the Company consumes 40% of the energy generated from the Solar Arinos (approximately 45 average megawatts) and will acquire approximately 23 MWm from four Barro Alto SPEs of Newave Energia, when they start operations. ● Gerdau has entered into agreements to fully acquire 100% of three other SPEs of the Barro Alto Solar Park (Barro Alto V, Barro Alto VI and Barro Alto VII), thereby obtaining the right to all the energy to be generated by them, estimated at approximately 43 average megawatts (MWm) ● Barro Alto Solar Park is scheduled to start operations in 2026. ● On January, 21, 2025, Gerdau has entered into contracts for the acquisition of Small Hydroelectric Plants (SHPs) named Garganta da Jararaca and Paranatinga II. The SHPs Garganta da Jararaca and Paranatinga II are located in the state of Mato Grosso, and each has an installed capacity of 29MW, with an average of 21MW and 17MW of assured energy, respectively. 34 Table of Contents In Brazil, natural gas is currently supplied to the Company’s industrial units under two types of contracts: ● Contracts in the Regulated Contractual Environment, in which the Company is a “Captive Consumer”, are used at the following units: Açonorte, Araucária, Caucaia, Cearense, Mogi das Cruzes and São José dos Campos. ● Contracts executed in the Free Market Environment, in which Gerdau is a “Free Consumer,” are used by the following units: Ouro Branco, Cosigua, Charqueadas, Rio Grandense, Araçariguama, Pindamonhangaba and Cilindros. The Várzea do Lopes, Miguel Burnier, São Caetano do Sul, Sete Lagoas, Cumbica, Cotia, Barão de Cocais and Divinópolis units do not have access to natural gas supplies. In the United States, there are essentially two types of electricity markets: regulated and deregulated. In the regulated market, contracts are approved by Public Utility commissions and are subject to an approved rate of return. These regulated tariffs are specific to local distributors and generally reflect the utilities transmission, generation capital and operational costs including fuel. In deregulated markets, the price of electricity has three main components: generation capital costs, transmission costs and variable costs. The variable cost is set by the marginal resource and fluctuates with demand and fuel cost. Natural gas in the United States is mostly deregulated. While in general, the U.S. energy market is benefiting from the increased exploration of shale gas, the environmental goals of decarbonization have resulted in natural gas scarcity during periods of high electricity and heating demand causing shortages and price volatility of natural gas and electricity. In Uruguay, electricity is purchased under agreements that are renewed automatically on an annual basis from the state-owned utility UTE. Natural gas is purchased from Montevideo Gas with prices set by the Argentinean export tariff agreement (fuel oil as substitute). In Peru, the Company holds an electricity supply contract valid from January 2023 to December 2034. Additionally, it has a natural gas supply contract spanning from January 2025 to December 2034. The natural gas is supplied as LNG (Liquefied Natural Gas), transported by trucks, decompressed, and gasified for distribution through the internal network to support production processes. In Argentina, natural gas agreements are renewed annually with private companies. In 2008, Gerdau Sipar signed a long-term agreement with a private company to supply the electrical needs of the plant. In Mexico, electricity is purchased under agreements regulated by the state-owned utility Companía Federal de Electricidad (CFE). The natural gas agreements are annually renewed with private companies. Electricity and natural gas prices are indexed and adjusted monthly based on the NYMEX prices indexes. Technology and Quality Management All Gerdau mills have a Quality Management System supported by a wide range of quality control tools. Product development projects are headed by specialists who use quality tools such as, but not limited to, “Six Sigma” (a set of statistical methods for improving the assessment of process variables), DOE (Design of Experiment) and Process Analysis. In general, production, market developers, and quality teams are responsible for developing new products to meet customer and market needs. Given this level of quality management, mills are ISO 9001certified, and certain mills have additional certifications such as but not limited to IATF 16949 (Automotive Industry), ABS (American Bureau of Shipping), German Ü-Sign conformity mark (Ü-Zeichen) and AASHTO Product Evaluation for US highway and bridge construction. The Gerdau Quality Management System requires robust tests on products and processes to ensure that the specifications and requirements are met. A specially trained team and modern technologies guarantee high quality standards for the products manufactured. Gerdau’s market developers do planned visits, some are randomly selected, and some are scheduled visits, to its customers to identify new product development opportunities and check on the quality of the delivered products to guarantee the final user satisfaction for products purchased. Due to the specialized nature of its business, the Gerdau special steel mills are constantly investing in technological upgrading and in research and development. These mills are active in the automotive segment and maintain a technology department (Research and Development) responsible for new products and the optimization of existing processes. 35 Table of Contents International machinery manufacturers and steel technology companies supply most of the sophisticated production equipment that Gerdau uses. These suppliers generally sign technology transfer agreements with the purchaser and provide extensive technical support and staff training for the installation and commissioning of the equipment. Gerdau has technology transfer and benchmarking agreements with worldwide recognized performance companies. As is common with mini mill steelmakers, Gerdau usually acquires technology in the market rather than develops new technology through intensive process research and development, since steelmaking technology is readily available for purchase. The Company is not dependent on patents or licenses or new manufacturing processes that are material to its business. See item “Information on the Extent of the Company’s Dependence” for further details. Sales Terms and Credit Policy The Company’s Brazilian sales are usually made on a 21/28-day settlement CIF (Cost, Insurance and Freight) basis. Comercial Gerdau, the retail arm of Gerdau in Brazil, sells on 28-day settlement basis, mainly CIF. Brazilian customers are subject to a credit approval process. The concession of credit limits is controlled by a corporate-level system (ECC) that can be accessed by all sales channels. The credit and collection department are responsible for evaluating, determining and monitoring credit in accordance with the credit limit policy. This policy includes the active participation of staff from the various sales channels. At Comercial Gerdau, the criteria for retail sales also include practices such as the use of credit card services. Gerdau exports are guaranteed via letters of credit and/or pre-payment before the product is shipped. Exports to Gerdau’s subsidiaries may be sold on credit at market interest rates. Gerdau North American credit terms to customers are generally based on customary market conditions and practices. The Company´s North American business is seasonal, with orders in the second and third quarters tending to be stronger than those in the first and fourth quarters, primarily due to weather-related slowdowns in the construction industry. The Company´s Special Steel operations in the United States and Brazil have their own credit departments for customer credit analysis. The Company’s impairment loss on financial assets has been at low levels. On December 31, 2025, provision for expected credit losses was 1.9% based on gross account receivables per Note 5 to the Consolidated Financial Statements, compared to 2.2% on December 31, 2024, and 1.8% on December 31, 2023. Gerdau has improved its credit approval controls and enhanced the reliability of its sales process using risk indicators and internal controls. Insurance The Company maintains insurance coverage in amounts that it believes suitable to cover the main risks of its operating activities. The Company has purchased insurance for its integrated mill Ouro Branco to insure against operating losses, which covers assets of approximately US$ 7.9 billion (R$ 43.2 billion as of December 31, 2025), including material damage to installations of US$ 7.6 billion (R$ 41.7 billion as of December 31, 2025) and losses of gross revenues of US$ 275.7 million (R$ 1.5 billion as of December 31, 2025), such as halts in production due to business interruptions caused by accidents for a period up to twelve months. The Company’s current insurance policy relating to the Ouro Branco mill remains effective until May 31, 2026. The Company’s mini mills are also covered under insurance policies which insure against certain operational losses resulting from business interruptions. Trade Investigations and Government Protectionism Over the past several years, exports of steel products from several companies and countries, including Brazil, have been subject to antidumping, countervailing duties and other trade-related investigations in importing countries. Most of these investigations resulted in duties and/or volume quotas limiting the investigated companies’ ability to access such import markets. Prior to 2025, the U.S. managed steel trade through Section 232 tariffs, initially implemented at 25% in 2018 for national security reasons. Over time, this framework evolved into a network of bilateral agreements: Australia received a full exemption, while countries like South Korea, Brazil, and Argentina moved to “hard-cap” quotas. Additionally, tariffs were removed for Canada and Mexico in 2019 in favor of volume monitoring, and by 2022, the Biden administration had transitioned tariffs for the EU, UK, and Japan into tariff-rate quotas. 36 Table of Contents This regulatory environment shifted on February 18, 2025, with a proclamation terminating these exceptions to restore domestic capacity utilization to the critical 80% threshold. The new measures addressed transshipment concerns—specifically Chinese steel entering via Mexico—and expanded the 25% duty to previously exempt regions like Ukraine and to various derivative steel products. This overhaul also ended the product-specific exclusion process for importers to ensure the tariffs’ objectives were not undermined. By June 2025, the administration intensified these protections by raising the standard Section 232 rate to 50%, with the UK remaining at 25% pending the finalization of the U.S.-UK Economic Prosperity Deal (EPD). These measures are set to not only increase tariffs on steel imports, but limit import volume as well, which could significantly affect the export volumes of some companies and redirect the export flow to other regions. Finally, given the evolving nature of the current U.S. trade environment, there is no guarantee that the 50% steel tariffs will remain in place. These protections, currently benefiting domestic production, could be modified, rescinded, or diluted through legislative changes, executive orders, or legal rulings. Should these tariffs be lifted or weakened, a subsequent rise in foreign steel imports would likely exert downward pressure on U.S. steel prices. Such a shift in the market would potentially result in a significant adverse effect on our North American revenues, cash flow, and overall financial results. Material effects of government regulation on the Company’s activities The Company’s steel production activities are not subject to special authorizations other than the licenses and permits typical to the industry. The Company maintains a good relationship with the government agencies responsible for issuing common authorizations and does not have any history of problems in obtaining them. Gerdau’s mining operations in Brazil are subject to the rules of the Brazilian Mining Code and its regulation (Decree-Law 227, of February 28, 1967, and Decree 9,406, of June 12, 2018) and to the applicable mining legislation, with mining exploration governed by Mining Property Rights and Concessions. Gerdau acquired the surface of the properties located in the polygon of the respective mining rights, as well as all other Mining Property Rights and Concessions, under an Agreement for the Sale of Assets and Assignment of Rights entered into by and between Gerdau Açominas S.A. and Companhia Paraibuna de Metais, Siderúrgica Barra Mansa S.A., Votorantim Metais Ltda., and Votorantim International Holding N.V., on May 19, 2004. The Company’s mining exploration activities are subject to the conditions and limitations imposed by the Federal Constitution of Brazil, the Brazilian Mining Code and related laws and regulations, which include requirements connected to, among other factors, how mineral deposits are used, occupational safety and health, environmental protection and restoration, pollution prevention and the health and safety of the local communities where the mines are located. The Brazilian Mining Code also establishes some requirements for the submission of notifications and information. Companies authorized to economically explore mineral resources are required to pay royalties to the Federal Government, which distributes most of them to States and Municipalities. On July 26, 2017, Provisional Presidential Decree 789/17 was published, which was later converted into Federal Law 13,540/17, amending Federal Laws 7,990/89 and 8,001/90, which provide for the Financial Compensation for Exploration of Mineral Resources (CFEM). For iron ore, the rate is fixed at 3.5%. In this case, upon a justified need, the regulatory entity of the mining sector could exceptionally reduce the iron compensation rate from 3.5% to as low as 2% to not adversely affect the economic feasibility of deposits with low performance and profitability due to the iron content, production scale, payment of taxes and number of employees. Gerdau holds environmental licenses for commercial operation of the mines located in the cities of Miguel Burnier/Ouro Preto and Várzea do Lopes/Itabirito in the Brazilian state of Minas Gerais. 37 Table of Contents The mining rights held by Gerdau cover 8,837.19 hectares, and the concessions are valid until the mining deposits are exhausted, provided the legal requirements are fulfilled annually.

Mining Assets Iron ore mines Gerdau’s activities related to the iron ore mines began after acquiring the mining rights from the Votorantim Group, in the cities of Ouro Preto (district of Miguel Burnier), Itabirito and Barão de Cocais, in 2004. These areas are located in the Iron Quadrilateral region of Minas Gerais state, in Brazil, one of the country’s most prominent mineral regions, as shown in the following figure. 42 Table of Contents Location of Gerdau’s mining operations The current and future iron ore production units encompass mainly open-pit mines, processing plants, waste and tailing piles, and logistics and operational support infrastructure. The current iron ore production units are the following: ● Miguel Burnier/Dom Bosco Complex: includes the mines located in Miguel Burnier and in Dom Bosco; ● Várzea do Lopes Complex; ● Gongo Soco. 43 Table of Contents Location and Access Miguel Burnier/Dom Bosco Complex Miguel Burnier and Dom Bosco are located in the city of Ouro Preto, in the southwestern region of the Iron Quadrilateral region of Minas Gerais, in Brazil, around 80 km from Belo Horizonte and 5 km from Vila do Pires, on Highway BR-040. The Dom Bosco Mine is located approximately 11 km from the Miguel Burnier Mine. Vila do Pires is situated on both sides of Highway BR-040, in the northern region of the city of Congonhas. Access to the mines is via a five-kilometer road starting in the Vila do Pires next BR-040 Highway. Várzea do Lopes Complex Várzea do Lopes is located in the city of Itabirito, in the Iron Quadrilateral region of Minas Gerais, in Brazil, approximately 46 km from downtown Belo Horizonte. Access to the mine is from Belo Horizonte via Highway BR-040, heading towards Rio de Janeiro. Várzea do Lopes is located approximately 20 km from Miguel Burnier, in a straight line. Gongo Soco The mining rights, as well as the mine, were leased by the company SPE MSA Trindade Mineração Ltda. In 2024, MSA Trindade obtained the environmental license to operate the Gongo Soco mine. With this, it is expected that production will start during the first half of 2025. The image below represents what the Company believes to be the location of the current and eventual iron ore production units and their main access routes: Certification of Reserves and Future Investments On August 9, 2023, Gerdau received the report prepared by SRK Consulting, certifying the reserves of Miguel Burnier mine, located in the district of Ouro Preto (MG - Brazil) and an integral part of the Brazil Segment. 44 Table of Contents The certification is a significant milestone in Gerdau’s R$ 3.6 billion investments in the sustainable mining platform, aimed at providing high-quality and competitively priced ore for the Ouro Branco Unit, while also playing an important role in its decarbonization process. The investment will be spread between the years 2023 and 2026, with the amount allocated to 2025 already included in the investment Plan announced on February 19, 2025. According to the conclusions of the report, the Company now holds certified reserves of 476 million metric tonnes (Dry metric tonnes) of iron ore. The Report was prepared in accordance with subchapter 1300 of Regulation S-K issued by the U.S. Securities and Exchange Commission – SEC, adhering to the technical report standard established by said regulation. Considering the expected annual production level of 5.5 million metric tonnes (Wet metric ton, assuming a humidity of 10%) of iron ore, we believe that the certified reserves should provide a 40-years lifespan for the investment, reinforcing Gerdau’s commitment to the socioeconomic development of the state of Minas Gerais today and in the future. Investment Programs On February 19, 2025, Gerdau approved its investment plan in the amount of R$ 6.0 billion for 2025. This investment plan is divided into two fronts: (i) Maintenance and (ii) Competitiveness and it was concluded on December 31, 2025. In addition, the Company maintained the level of nearly R$1.1 billion in projects focused on environmental returns and safety initiatives, in line with building an increasingly sustainable future and our commitment to people’s safety. On October 1st, 2025, Gerdau approved its investment plan in the amount of R$ 4.7 billion for 2026. This investment plan is divided into two fronts: (i) Maintenance and (ii) Competitiveness. Regarding Maintenance projects, the Company estimates an average investment of nearly R$3.0 billion/year over the next five years, considering assets’ current status, the current exchange rate and inflation levels. Maintenance projects are associated with the concept of reinvestment of depreciation over the years to ensure the good functioning of plants, while Competitiveness projects are related to the growth, technological updating and modernization of the business segments, with a focus on improving Environmental, Social and Governance (ESG) practices and sustainable development. The Company’s expenditure in its investment plan will be directly related to market conditions and the economic scenario of the countries and the sectors in which it operates. Environmental Issues Gerdau is currently in compliance with environmental regulations. The Company also believes that there are no environmental issues that could affect the use of its fixed assets. In 2025, Gerdau invested R$ 640.95 million in the improvement of its eco-efficiency practices and in technologies for the protection of the air, water and soil. Environmental Regulations In all of the countries in which the Company operates, it is subject to federal, state and municipal environmental laws and regulations governing, but not limited to, the air emissions, wastewater discharges and solid and hazardous waste handling and disposal. Its manufacturing facilities have been operating under the applicable environmental rules. The respective permits and licenses require compliance with conditions and various performance standards, which are monitored by regulatory authorities. The Company employs a staff of experts to manage all phases of its environmental programs and uses outside experts where needed. The Company works to ensure that its operations maintain compliance in all material respects with the applicable environmental laws, regulations, permits and licenses currently in effect. When Gerdau acquires new plants, it conducts an assessment of potential environmental issues and prepares a work plan in compliance with the local authorities. 45 Table of Contents In most countries, both federal and state governments have the power to enact environmental protection laws and issue regulations under such laws. In addition to those rules, the Company is also subject to municipal environmental laws and regulations. Under such laws, individuals or legal entities whose conduct or activities cause harm to the environment are usually subject to criminal, civil and administrative sanctions, as well as any costs to repair the actual damages resulting from such harm. The steel industry uses and generates substances that can cause environmental damage. The Company’s management conducts surveys periodically to identify areas potentially impacted and recorded as its best estimate of the costs for inspecting, treating and cleaning potentially impacted areas the amounts of R$ 620,665 on December 31, 2025 (R$ 382,800 recognized as current liabilities and R$ 237,865 as non-current liabilities), R$ 659,082 on December 31, 2024 (R$ 245,429 recognized as current liabilities and R$ 413,653 as non-current liabilities) and R$ 517,669 on December 31, 2023 (R$ 139,395 recognized as current liabilities and R$ 378,274 as non-current liabilities). The Company adopted assumptions and estimates to determine the amounts involved that could vary in the future due to the conclusion of the inspection and the assessment of the actual environmental impact at the time of the ultimate settlement. In the Gerdau Corporate Environmental Guideline, there are environmental management practices the adoption of which is aimed at optimizing natural resources and minimizing environmental impacts. Among these practices, there is the management of contaminated areas, which aims to ensure controls and preventive or corrective measures to avoid soil and water body contamination. The management process includes communication, assessment, identification, and remediation. Provisioning costs must cover remediation and monitoring activities, being sufficient to meet the Company’s plans. Units or operations in the process of closing activities at Gerdau must also undergo evaluation. Closure plans are updated periodically, and information is monitored according to the governance established in the Policy, with evaluation by technical and financial areas. See Note 22 – Environmental Liabilities. Brazilian Environmental and Regulatory Legislation The Company’s activities are subject to wide-sweeping Brazilian environmental legislation at the federal, state and municipal levels that encompass, among other aspects, the dumping of effluents, atmospheric emissions and the handling and final disposal of dangerous waste, as well as the obligation to obtain operating licenses for the installation and operation of potentially polluting activities. Brazilian environmental legislation provides for the imposition of criminal, civil and administrative liabilities on individuals and legal entities that commit environmental crimes or infractions, as well as for the obligation to repair the environmental damage caused. Any potential environmental crimes or infractions could subject the Company to penalties that include: ● fines that at the administrative level could reach as high as R$ 1 billion, and that could be influenced by the wrongdoer’s economic capacity and past record, as well as the severity of the facts and prior history, that could be potentially doubled or tripled in case of repeat offenders; ● suspension of or interference in the activities of the respective enterprise; and ● loss of benefits, such as the suspension of government financing and the inability to qualify for public bidding processes and tax breaks. The application of environmental liability in the criminal sphere depends on evidence of intent (intention) or fault (negligence and/or recklessness) and, is considered subjective. Therefore, individuals only would be prosecuted or convicted to the extent of their action, intention or fault. In the case of the administrative sphere, recent judicial precedents provide for subjective environmental liability as well, although most environmental agencies apply administrative environmental liability regardless of proof of intent or fault. In the civil sphere, environmental damage results in joint and several liability as well as strict liability. This means that the obligation to repair the environmental damage may affect all those directly or indirectly involved, regardless of intent or fault. In this case, acknowledging the causal link between the action and the damage is enough to imputation of civil responsibility. As a result, hiring of outsourced companies to intervene in its operations to perform services such as final disposal of solid waste does not exempt the Company from liability for any environmental damage that may occur. Environmental legislation also provides for piercing the corporate veil, affecting shareholder assets, whenever the lack of solvency of an entity represents an impediment to recovery of environmental damages. 46 Table of Contents North American Environmental Legislation The Company is required to comply with a complex and evolving body of Environmental, Health and Safety Laws (EHS Laws) concerning, among other things, air emissions, discharges to soil, surface water and groundwater, noise control, the generation, handling, storage, transportation and disposal of toxic and hazardous substances and waste, the clean-up of contamination, indoor air quality and worker health and safety. These laws vary by location and can fall within federal, provincial, state or municipal jurisdictions. Most EHS Laws are of general application but result in significant obligations in practice for the steel sector. For example, the Company is required to comply with a variety of EHS Laws that restrict emissions of air pollutants, such as lead, particulate matter. Because the Company’s manufacturing facilities emit significant quantities of air emissions, compliance with these laws does require the Company to make investments in pollution control equipment and to report to the significant government authority if any air emissions limits are exceeded. The government authorities typically monitor compliance with these limits and use a variety of tools to enforce them, including administrative orders to control, prevent or stop a certain activity; administrative penalties for violating certain EHS Laws; and regulatory prosecutions, which can result in significant fines and (in rare cases) imprisonment. The Company is also required to comply with a similar regime with respect to its wastewater. EHS Laws restrict the type and number of pollutants that Company facilities can discharge into receiving bodies of waters, such as rivers, lakes and oceans, and into municipal sanitary and storm sewers. Government authorities can enforce these restrictions using the same variety of tools noted above. The Company has installed pollution control equipment at its manufacturing facilities to address these emissions and discharge limits and has an environmental management system in place designed to reduce the risk of non-compliance. Environmental Permits According to Brazilian environmental legislation, the proper functioning of activities considered effectively or potentially polluting or that in some way could cause environmental damage requires environmental licenses. This procedure is necessary for both the activity’s initial installation and operating phases as well as for its expansion phases, and these licenses must be renewed periodically. The Brazilian Institute for the Environment and Renewable Resources (IBAMA) has jurisdiction to issue licenses for projects with national or regional environmental impacts. In all other cases, the state environmental agencies have jurisdiction, and, in the case of local impact, the municipal agencies have jurisdiction. Environmental licensing of activities with significant environmental impacts is subject to a Prior Environmental Impact Study and respective Environmental Impact Report (EIA/RIMA), as well as the implementation of measures to mitigate and compensate for the environmental impact of the project. In most cases that involve significant environmental impact, the licensing process includes the issuance of three licenses: Pre-License (LP), Installation License (LI) and Operational License (LO). These licenses are issued in accordance with each phase of project implementation, and maintaining their validity requires compliance with the requirements established by the environmental licensing agency. The failure to obtain an environmental license, regardless of whether or not the activity is actually harming the environment, is considered an environmental crime and an administrative infraction, and may subject the wrongdoer to administrative fines, at the federal level (subject to being doubled or tripled in the case of repeat violations), an Environmental legislation also provides for piercing the corporate veil, affecting shareholder assets, whenever the lack of solvency of an entity represents an impediment to recovery of environmental damages and the suspension of operations. The Operational License (LO) must be renewed periodically. The Company’s operations currently comply with all legal requirements related to environmental licenses. However, any delay or refusal on the part of environmental licensing agencies to issue or renew these licenses, as well as any difficulty on its part to meet the requirements established by these environmental agencies during the course of the environmental licensing process, could jeopardize or even impair the installation, operation and expansion of new and current projects. 47 Table of Contents Decarbonization Strategy Gerdau determines the most significant material issues linked to the SDGs (Sustainability Development Goals) through a tool celled materiality matrix. The materiality matrix enables us to guide our strategy and management initiatives and guide the way in which we communicate with our stakeholders and society in general. One of the issues identified as most significant was “Climate change management.” GHG emissions are a key issue in the debate on climate change and a sensitive point for the steel industry, given the level of emissions from its production facilities in relation to the industrial sector. The Company defines its risk management guidelines and procedures based on business analysis, including issues related to climate change and the Sustainability Scorecard indicators. Industry trends that can impact business in the short-, medium- and long-term, as well as environmental, social and governance factors, image and legislation are assessed. The identified risk factors concerning climate change are related to unexpected interruptions in the production capacity of the Company’s main units and facilities that would increase production costs, reducing sales and earnings in the affected period. The Company could be affected by risks, such as: ● Reduced availability of electricity arising from a period of water crisis: the production of crude steel is an electricity-consuming process, especially in steel mills that use electric arc furnaces. Electricity is an important component for the production, as is natural gas, although to a lesser extent. Electricity cannot be replaced by another energy source in the Company’s mills and rationing or interruptions in supply can affect the production of these units. ● Fires or severe weather conditions: Unforeseen periods of drought can impair the performance of our forest areas, reducing the availability of the bio-reducer for our operating units that use this input; Floods can result in unforeseen periods of production stoppage, among others. ● Water shortage resulting from a period of water crisis: Reduction of water withdrawal for the production process, leading to a reduction in production. Such risks would increase production costs, reducing sales and earnings in the affected period as a result of unexpected events. Consequently, the Company is susceptible to periods of stoppage or reduction of production in the steel mills, which may also occur in the future. Interruptions in production capacity may adversely affect Gerdau’s productivity and operating results. In addition, any interruption in production capacity may require additional troubleshooting expenses which would impact the Company’s cash flow. As a result, long business interruptions can also damage the Company’s reputation and lead to the loss of customers, which can have a negative impact on business, results of operations and cash flows. The Company could also be affected by transition risks related to policy, legal, technology, market and reputation risks. In 2021, the Company prepared the GHG inventory of all of its global industrial units (base year, 2020). Since then, the data has been audited by a third party, following ISO 14064 and ISAE 3410 (GHG emissions inventory), and reporting its GHG emissions management on CDP Climate Change since 2021 (2020 base year), CDP is a reference entity in the evaluation of sustainable actions. In 2025 (2024 base year), Gerdau achieved the A- score, reaching the climate leadership level, according to CDP, reinforcing the Company’s commitment to the sustainability of its operations. Also, in 2025 (base year 2024), Gerdau reported CDP Water Security and received a B score, reinforcing the Company’s commitment to transparency. With the support of specialized consultants, we study the scenarios of productive and technological changes with the lowest effective carbon cost to define goals and guide our strategy. Consistent with this, the Company adopted the MACC “Marginal Cost Curve Abatement” and structured and published on February 1, 2022 the goal of reducing GHG emissions related to Scopes 1 and 2 by 2031, from 0.93 t of CO₂e per tonne of steel produced to 0.82 t of CO₂e per tonne of steel produced. Failure to achieve the target is a risk associated with the organization’s reputation, and it is mitigated through emissions projections monitoring in accordance with operation and investment plans, incorporating additional actions, if necessary. This target is factored in our Long-Term Incentive Plan. Gerdau’s production model and efforts for over a century have placed the Company at the vanguard on the issue of GHG emissions. Currently, we have one of the lowest emission averages in the steel industry, which is equivalent to approximately half of the global industry average. 48 Table of Contents ● Around 70% of the steel we produce comes from recycling of ferrous scrap: transforming about 10 million tonnes of scrap into steel. This enables us to promote a circular economy, saving natural resources and reduce energy consumption and GHG emissions. ● The Company has more than 200,000 hectares of forests. Our planted forests are sources of renewable raw material in the production of charcoal, a bioreducer used to produce pig iron, resulting in decreased emissions of GHG. ● Currently, we are leaders in managing GHG emissions and being well thought of as a benchmark for industry entities. Our constant efforts include the use of renewable sources, recycling, reduction of raw material consumption and energy efficiency. Our goal of reduction from 0.93t CO2e / t steel (base year 2020) to 0.82t CO2e / t steel, by 2031, in scopes 1 and 2 prioritizes: ● Greater energy and operational efficiency; ● Expansion of scrap use; ● Investment in renewable energy; ● Exploration of viable new technologies; and ● Maximization of the potential of the forestry base. The Company aims to be carbon neutral by 2050; for this, disruptive technologies will be necessary in steel production, which are not yet economically and operationally feasible on an industrial scale. No assurance can be given that it can be achieved, since there are externalities involved that we do not control; nonetheless, to contribute to this outcome, we continue to study and collaborate with diverse partners and entities in the sector to seek low carbon solutions. Public policies and measures to reduce GHG emissions from industrial processes will also be necessary. Our efforts are also dedicated to clean and renewable energy solutions. The Company has already announced the construction of a solar complex in Brazil. Moreover, we will continue to streamline our production processes and invest in new energy matrices and new technologies. In Canada, the three Gerdau mills are required to report facility-level GHG emissions and production data with verification by a third-party. Manitoba Mill is regulated by the Canadian Federal Greenhouse Gas Pollution Pricing Act, which has been in effect since 2019, setting a carbon price at CAD 95/tCO2e for 2025 and includes the Output-Based Pricing System (OBPS) Regulations. Facilities operating above the standard pay an excess emissions charge (CAD 95/tCO2e for 2025, rising $15/t per year out to 2030), while facilities operating below (better than) the standard can receive credits. Under the Canada GHG program, facilities are granted allowances based on our production x output-based standard(s) for each activity (in our case, both EAF steel and hot-rolled steel). The resulting balance is the difference between the allocations provided and the actual emissions. Emission units are not transferable outside of the Federal OBPS. Since January 1, 2022, the Whitby and Cambridge Mills have been regulated by the Provincial (Ontario) Emissions Performance Standards (EPS) Regulation. The Federal Greenhouse Gas Pollution Pricing Act applies a regulatory charge on fuel, but a facility is exempt from the carbon tax when registered under the Ontario EPS. The EPS includes performance standards, called Baseline Emission Intensities (BEIs) for the industrial facilities. Facilities operating above the standard pay an excess emissions charge (currently CAD 95/tCO2e for 2025 and rising $15/t per year in accordance with the Federal pricing), while facilities operating below (better than) the standard can receive credits. Under the EPS program, facilities are granted allowances based on our production x output-based standard(s) for each activity (in our case, both EAF steel and hot-rolled steel). The resulting balance is the difference between the allocations provided and the actual emissions. As Gerdau operates two facilities under the Ontario EPS program, we can move allowances within the Company to assist with any carbon compensation obligations. In Mexico, our operations in Tultitlán and La Presa are currently regulated by the states where they are located, which levy carbon-emission taxes. These taxes do not generate a significant financial impact. 49 Table of Contents Areas of permanent forest preservation and legal reserves Some activities of the Company, mainly those involving reforestation to produce thermal-reducer used in its industrial units, are subject to the Brazilian Forest Code. The Code determines that some areas, due to their importance for the preservation of the environment and water resources, are considered permanent preservation areas (APP), such as, for example, areas adjacent to rivers or natural or artificial reservoirs. At Gerdau’s forestry units, permanent preservation areas are an integral part of the business, being protected and in compliance with the legislation. Moreover, depending on the region where the property is located, the Code requires rural land owners to restore and preserve between 20%, 35% or 80% of areas containing native vegetation. The maintenance of these percentages of native vegetation is important because it guarantees the preservation of the local natural vegetation, perpetuating the genetic resources and the biodiversity of each Brazilian biome. Gerdau maintains its Legal Reserve areas preserved and in accordance with governing legislation.

The following discussion of the Company’s financial condition and results of operations should be read in conjunction with the Company’s audited Consolidated Financial Statements of financial position as of December 31, 2025 and 2024 and for each year in the three year period ended December 31, 2025, included in this Annual Report that have been prepared in accordance with IFRS Accounting Standards, as well as with the information presented under “Presentation of Financial and Other Information” and “Selected Financial and Other Information of Gerdau.” Starting with the disclosure of the results of 2025, the Company began to disclose the information and results of its business segments as follows: ● Brazil Segment: includes the long, flat and special steel operations and the iron ore operation located in Brazil and joint ventures and associated companies located in Brazil; ● North America Segment: includes the long and specialty steel operations located in Canada and the United States and the joint ventures located in Canada and Mexico; and ● South America Segment: includes the operations in Argentina, Peru and Uruguay. With these changes, the information and results of the former Special Steel Segment, which included the special steel operations located in Brazil and the United States, are now disclosed jointly with the other segments, according to their geographic location, as the Brazil Segment and the North America Segment, respectively. This new format for disclosing information and results is in line with recent changes in the global steel industry scenario, which have led to an increasing regionalization of markets, business dynamics and local currencies of these operations, improving the presentation of Gerdau’s results in Brazil and North America, the main regions in which it operates. The comparative information of the segments presented in Financial Statements for the years ended on December 31, 2024 and December 31, 2023 has been adjusted to reflect this new composition. 50 Table of Contents The following discussion contains forward-looking statements that are based on management’s current expectations, estimates and projections and that involve risks and uncertainties. The Company’s actual results may differ materially from those discussed in the forward-looking statements because of various factors, including those described in the sections “Forward-Looking Statements” and “Risk Factors.” The primary factors affecting the Company’s results of operations include: ● Economic and political conditions in the countries in which Gerdau operates, especially Brazil and the U.S.; ● The fluctuations in the exchange rate between the Brazilian real and the U.S. dollar; ● The cyclical nature of supply and demand for steel products both inside and outside of Brazil, including the prices for steel products; ● The Company’s level of exports; and ● The Company’s production costs. Brazilian Economic Conditions The Company’s results and financial position depend largely on the situation of the Brazilian economy, most notably economic growth and its impact on steel demand, financing costs, the availability of financing and the exchange rates between Brazilian and foreign currencies. Since 2003, the Brazilian economy has become more stable, with significant improvement in the main indicators. The continuity of the macroeconomic policies focused on tax matters, the inflation-targeting system, the adoption of a floating foreign exchange rate, the increase in foreign investment and compliance with international financial agreements, including the full repayment of debt with the International Monetary Fund, contributed to the improved economic conditions in Brazil. In 2025, Brazilian GDP increased 2.3% (equivalent to US$ 2.5 trillion Nominal GDP) driven by the agriculture and services sectors. Inflation, as measured by the IPCA index, was 4.3%. The average CDI rate in the year was 14.3%. The Brazilian real appreciated by 11.1% against the U.S. dollar, ending the year at R$ 5.50 to US$ 1.00. In 2024, Brazilian GDP increased 3.4% (equivalent to US$ 2.2 trillion Nominal GDP) driven by services and industrial sectors. Inflation, as measured by the IPCA index, was 4.8%. The average CDI rate in the year was 10.9%. The Brazilian real depreciated by 27.9% against the U.S. dollar, ending the year at R$ 6.19 to US$ 1.00. In 2023, Brazilian GDP increased 2.9% (equivalent to US$ 1.9 trillion Nominal GDP) driven by services, industrial and agribusiness sectors. Inflation, as measured by the IPCA index, was 4.6%. The average CDI rate in the year was 13.0%. The Brazilian real appreciated by 7.1% against the U.S. dollar, ending the year at R$ 4.84 to US$ 1.00. The interest rates the Company pays depend on multiple drivers, such as movements in benchmark interest rates (often influenced by inflation), the ratings assigned by credit rating agencies that assess the Company, and the pricing of the Company’s debt securities traded in the secondary market. To reduce this exposure, the Company from time to time enters into hedging arrangements to mitigate rate fluctuations. 51 Table of Contents The table below presents GDP growth, inflation, interest rates and the foreign exchange rate between the U.S. dollar and the Brazilian real for the periods shown. 2025 2024 2023 Actual GDP growth 2.3 % 3.4 % 2.9 % Inflation (IGP-M) (1) (1.1) % 6.5 % (3.2) % Inflation (IPCA) (2) 4.3 % 4.8 % 4.6 % CDI rate (3) 14.3 % 10.9 % 13.0 % Depreciation (appreciation) in the Brazilian real against the U.S. dollar (11.1) % 27.9 % (7.1) % Foreign exchange rate at end of year — US$ 1.00 R$ 5.5024 R$ 6.1923 R$ 4.8413 Average foreign exchange rate — US$ 1.00 (4) R$ 5.5855 R$ 5.3895 R$ 4.9841 Sources: Getúlio Vargas Foundation, Central Bank of Brazil and Bloomberg (1) Inflation as measured by the General Market Price index (IGP-M) published by the Getúlio Vargas Foundation (FGV).

U.S. Economic Conditions In view of the size of the Company’s operations in the United States, U.S. economic conditions have a significant effect on the Company’s results, particularly with regards to U.S. economic growth and the related effects on steel demand, financing costs and the availability of credit. In 2025, according to the IMF (International Monetary Fund) October 2025 report, the U.S. Real GDP increased by 2.0%. Inflation, as measured by the CPI, ended the year at 2.7% (December-to-December), with an average annual rate slightly higher due to mid-year volatility. The average Fed Funds rate (the interest rate established by the U.S. Federal Reserve) for 2025 was approximately 4.1%, reflecting a gradual decrease from the prior year as the Fed implemented three quarter-point rate cuts during the second half of the year. In 2024, according to the IMF (International Monetary Fund) October 2024 report, the U.S. Real GDP increased 2.8%. Inflation, as measured by the CPI, was 3.0%. The average Fed Funds rate (the interest rate established by the U.S. Federal Reserve) was 5.3%. In 2023, according to the IMF (International Monetary Fund) October 2023 report, the U.S. Real GDP increased 2.1%. Inflation, as measured by the CPI, was 4.1%. The average Fed Funds rate (the interest rate established by the U.S. Federal Reserve) was 5.5%.

A portion of Gerdau’s trade accounts receivable, trade accounts payable and debt is denominated in currencies other than the respective functional currencies of each subsidiary. The functional currency of the Brazilian operating subsidiaries is the Brazilian real. Brazilian subsidiaries have some of their assets and liabilities denominated in foreign currencies, mainly the U.S. dollar. The foreign exchange effect on translation of foreign subsidiaries is recorded directly in shareholders’ equity. Foreign exchange gains and losses on transactions, including the exchange gains and losses on some non-real denominated debt of the subsidiaries in Brazil are recognized in the income statement. However, gains and losses from debts contracted for acquisition of overseas investments are designated as a hedge of net investment in foreign subsidiaries and are also recorded directly in shareholders’ equity. The operations of Gerdau in Brazil have both liabilities and assets denominated in foreign currency, with the amount of assets exceeding the amount of liabilities. The effect of the valuation of the Brazilian real versus other currencies (mainly the U.S. dollar) has a net positive effect in our shareholders’ equity. The cyclical nature of supply and demand for steel products including the prices of steel products The prices of steel products are generally sensitive to changes in world and local demand, which in turn are affected by economic conditions in the world and in the specific country. The prices of steel products are also linked to available installed capacity. Most of the Company’s long rolled steel products, including rebars, merchant bars and common wire rods, are classified as commodities. However, a significant portion of the Company’s long-rolled products, such as special steel, wire products and drawn products, are not considered commodities due to differences in shape, chemical composition, quality and specifications, with all of these factors affecting prices. Accordingly, there is no uniform pricing for these products. Over the past years, global steel prices have experienced notable volatility due to various macroeconomic factors, supply chain disruptions, and geopolitical events. In 2021, steel prices surged to record highs driven by strong post-pandemic recovery, supply constraints, and increased infrastructure spending in major economies such as the United States and China. Most of long rolled steel products saw sharp price increases due to heightened construction activity and supply shortages. However, in 2022, steel prices declined as demand weakened due to rising inflation, tighter monetary policies, and slowing economic growth, particularly in China, the world’s largest steel consumer. Additionally, the war in Ukraine disrupted global steel and raw material supply chains, leading to further market volatility. For instance, Turkish rebar export prices, a key reference point for the global rebar market, spiked in early 2022 due to supply concerns, but later softened as construction activity slowed. Other products, such as merchants bars and beams, widely used in industrial and manufacturing applications, also faced price corrections as steel mills increased production in response to high prices from the previous year. In 2023 and 2024, steel markets remained uncertain and saw a downward trend in international steel prices, mainly due to oversupply and a slow recovery in China’s real estate sector. Additionally, government interventions, such as export restrictions and import tariffs, further influenced pricing dynamics, affecting the competitiveness of steel producers worldwide. In 2025, the global steel market remained pressured, with prices generally stable to slightly lower compared to 2024. Persistent oversupply (particularly from China) continued to weigh on international markets, as exports stayed elevated amid a still-fragile recovery in the Chinese real estate sector. In the United States, domestic prices showed relative resilience supported by infrastructure spending and trade measures, although levels remained well below the 2021 peaks. Long steel products, such as rebar and merchant bars, experienced moderate volatility, largely reflecting regional construction trends and increased import penetration. Export levels — during periods of lower domestic demand for the Company’s products, the Company actively pursues export opportunities for its excess production to maintain capacity utilization rates and shipments. During periods of higher domestic demand for its products, export sales volumes may decline as the Company focuses on satisfying domestic demand. Gerdau exports products from Brazil to customers in other continents with whom we have long-established commercial relations. In 2025, exports were 18.2% higher than 2024, going from 1.1 to 1.3 million tonnes, which represented 21.4% of total shipments from Brazil operations. Export revenue totaled R$ 4,792 million in 2025 (R$ 3,822 million in 2024). 53 Table of Contents Production costs — raw materials account for the highest percentage of the Company’s production costs. Metallic inputs, which include scrap, pig iron, iron ore, coke and metallic alloys, represented approximately 47.4% of production costs in 2025, while Energy and Reducing Agents, which represent the cost of coal, electricity, oxygen, natural gas and fuel oil, accounted for 13.1%. Personnel totaled 12.6% of production costs and Specific Materials, which includes refractories, electrodes, rolling cylinders, rollers, guides, carburants and lime, were 10.2% of total production costs. The table below presents the production costs breakdown by business segment: Production Costs Breakdown in 2025, 2024 and 2023 (%) Consolidated Brazil Business Segment North America Business Segment South America Business Segment % of costs 2025 2024 2023 2025 2024 2023 2025 2024 2023 2025 2024 2023 Personnel and Others 17.8 18.1 18.4 16.8 15.3 18.4 19.4 18.6 17.2 13.1 14.1 13.2 Maintenance 7.1 7.2 7.6 4.9 4.5 6.1 9.0 10.6 10.6 4.0 5.5 4.9 Depreciation 4.0 4.0 3.9 6.0 4.9 5.4 4.0 3.1 2.6 2.0 1.7 1.3 Metallic Inputs 47.4 46.5 44.3 41.0 40.7 30.3 50.0 50.2 52.8 67.0 64.9 65.6 Energy and Reducing Agents 13.1 14.1 15.2 22.0 25.6 29.1 7.0 5.9 5.7 8.0 8.5 9.5 Specific Materials 10.2 10.2 10.7 10.0 9.0 10.7 11.0 11.6 11.1 5.0 5.3 5.5 Significant events affecting financial performance during 2025 In Brazil, the year was again marked by record steel import levels, totaling 6.4 million tonnes (including semi-finished products), a 7.4% year-over-year increase, according to Brazil Steel Institute data. The flat steel segment was the most affected, recording 29.6% higher imports throughout the year. This movement increased the steel oversupply in the domestic market, putting pressure on the local industry’s profitability and hindering shipment growth, despite a scenario of apparent consumption 3% higher than in 2024; Gerdau’s exports benefited from the devaluation of the Real, but the greater share of exports in the mix also contributed to the decline in Net sales in the period. The cost of goods sold was higher in 2025 versus 2024, driven by increased shipment volume and, mainly, by scheduled shutdowns and structural and operational adjustments necessary throughout the year to implement improvements and prepare for new investments at the Ouro Branco industrial unit. These factors temporarily raised fixed costs, raw materials, and maintenance. However, during the second half of the year, the industrial unit then recorded greater operational stability. In addition, the higher occupancy rate of mini mills contributed to cost dilution and efficiency gains, partially mitigating the effects seen earlier in the year. It is worth noting that, in 2024, costs of goods sold benefited from optimization initiatives and hibernations, which reduced the basis for comparison. Regarding the sectors in which Gerdau operates in Brazil, the construction sector had a firm performance in 2025, with estimated residential building launches growing by 29% compared to 2024, while sales increased by 5% in 2025. Higher family income, a lower unemployment rate, and improved public housing programs remained the highlights. The industry and manufacturing sectors had a stable year, with some steel-intensive segments presenting mixed results. While the light vehicle sector and green machinery achieved robust numbers, wind energy, heavy trucks, road transport equipment and white goods showed retractions in 2025 compared to 2024. 54 Table of Contents In North America, throughout 2025, the non-residential construction (especially data centers) and renewable energy sectors played a pivotal role in the North America shipment volumes, benefiting demand for downstream products, while we reduced volumes of rebar and semi-finished products, in line with our focus on a more profitable product mix. On the other hand, sectors demanding special steel faced more challenging dynamics. The automotive sector, for instance, remained impacted by uncertainties surrounding Section 232 tariffs developments and high interest rates, hindering the growth of light and heavy vehicle inventories in the region, while the oil and gas sector still shows signs of slowing down; Demand levels improved in 2025 driven by a strong customer preference for domestic materials, and by sectors with strong economic growth. The overall market remains uneven across different sectors of the economy, while the industrial sector was slower than previous years, non-residential construction, that also declined year-over-year, consumed a higher amount of steel, driven by AI infrastructure and renewable energy investments. According to US Census Bureau, total investments in construction (CPIP- Construction Put-in-Place) declined by approximately 2.0% through October 2025. The leading indicator for non-residential construction (ABI) remained under the expansion threshold for most of the year, closing 2025 at 48.5. The industrial sector demand was also pressured by the activity level, as shown by the Institute for Supply Management (ISM - PMI) index, which reached 44.9 points in December 2025, staying below 50 for the entire year. Finally, the overall increase in demand, growing preference for domestic materials and the strong activity in certain sectors of the economy have resulted in a favorable price environment for long steel in the U.S. In South America, steel production and shipments grew in 2025, fueled by increased volumes in the three countries where we operate; however, the key sectors served still showed weaker demand throughout the year. In Argentina, civil construction activity levels hit all-time lows, while in Uruguay, infrastructure works remained halted. On the other hand, in Peru, the order backlog remained resilient, driven by demand from the civil construction distribution sector. In the fourth quarter of 2025, due to the revision of the Capex investment plan for its industrial plants, representing a significant reduction compared to recent years, the level of asset utilization at certain industrial plants in the Brazil segment, and the expectation of a deterioration in economic conditions to a greater extent than that contemplated in previous period scenarios, tests performed on other long-lived assets identified impairment losses in fixed assets of the Brazil segment amounting to R$ 1,591,369, as compared to R$ 199,627 on December 31, 2024, resulting from recoverable value below the carrying amount. Also, in December 2025, the Company assessed the recoverability of goodwill in its business segments. The analyses carried out identified impairment losses in the Brazil segment in the amount of R$ 1,964,504. Therefore, the Company wrote off the entire goodwill of this segment in the amount of R$ 373,135, while the remaining portion of R$ 1,591,369 was recognized in fixed assets, as described in Note 29.2. No impairment losses were identified in 2024 and 2023. A. Results of Operations The following presentation of the Company’s operating results for the years ended on December 31, 2025, 2024 and 2023 is based on the Company’s Consolidated Financial Statements prepared in accordance with IFRS Accounting Standards included in this Annual Report.

Key factors included an imbalance between supply and demand, as well as developments in trade policies adopted by major economies. In this context, the sector continues to face challenges due to production overcapacity, particularly from China, whose volumes are still directed to other markets, heightening international competition. Gerdau operations reflected distinct dynamics between regions where the Company operates. In North America, the rebalancing of supply and demand evolved more favorably, creating conditions for price recovery and stronger results throughout the year. Conversely in Brazil, domestic dynamics remained significantly impacted by steel oversupply, particularly imported steel, coupled with sector-specific dynamics, putting pressure on operations’ volumes and margins. Throughout 2025, the Company advanced initiatives that will enhance assets’ competitiveness and continue to work to reinforce fair competitive conditions in Brazil, with an emphasis on the pivotal role of trade defense measures in bolstering local industry. In 2025, Gerdau’s net sales totaled R$ 69.9 billion, 4.2% higher than in 2024, fueled by increased shipment volume and more favorable pricing environment in North America, which accounted for more than 50% of consolidated sales for the year. These factors offset the more challenging pricing scenario in the Brazilian market throughout 2025. In 2024, Gerdau’s net sales were R$ 67.0 billion, down 2.7% from 2023, reflecting the cooling of sales prices of the main product lines at North America Segment from the second half of 2024. This movement was partially offset by the depreciation of the real against the dollar (+7.9%) and the price increase in some product lines at Brazil Segment. The shipments in 2024 decreased 3.0% compared to 2023, reflecting the effects explained above. In Brazil Segment in 2025, net sales went down 1.8% from 2024, due to a fierce competitive environment in the domestic market, marked by rising steel imports and the entry of new capacity players, which pressured prices in the common long and flat steel segments throughout the year. Despite shipment volume growth, the greater share of exports in the mix also contributed to the decline in Net sales in the period. The net sales per tonne decreased 4.5% in 2025 when compared to 2024 due to effects of lower prices in the Brazilian domestic market in light of a scenario of steel oversupply. In Brazil Segment in 2024, net sales went down 3.1% from 2023. The decrease of 1.3% in volume of sales was a consequence of excessive steel imports in Brazil. The net sales per tonne decreased 1.9% in 2024 when compared to 2023 due to effects of lower prices in the Brazilian domestic market. In 2025, due to the steel improvement in the North America Segment, as explained above, net sales were 12.1% higher in 2025 compared to 2024, fueled by shipment volume growth of higher value-added products and the gradual price recovery across key product lines throughout 2025. The net sales per tonne increased 2.4% in 2025 when compared to 2024 supported by higher value-added products and the gradual price recovery across key product lines throughout 2025. In the North America Segment in 2024, net sales were R$31.9 billion, resulting in a decrease of 3.8% compared to 2023, which were R$33.2 billion. The volume of sales in 2024 was 4.6 million tonnes, 3.5% lower than 2023, which was 4.7 million tonnes. The net sales per tonne decreased in 2024 when compared to 2023 due to volatility in the North America market. In South America Segment, net sales in 2025 came 3.4% lower than in 2024, reflecting strong pressure on prices in the regions where the Company operates and the impact of inflation adjustments in Argentina, factors that ultimately offset the positive effect of increased shipments for the year. The net sales per tonne decreased 12.2% in 2025 when compared to 2024 due to lower prices in the Segment. In the South America Segment, net sales in 2024 were R$ 5.8 billion, compared to R$ 5.1 billion in 2023, an increase of 12.5% in the year. The volume of sales in 2024 was 1.0 million tonnes, 10.2% lower than 2023, which was 1.1 million tonnes. The net sales per tonne increased in 2024 when compared to 2023 due to effects of exchange rate in the results of this Segment. 57 Table of Contents Year ended Net sales, cost of sales and Gross Profit(*) (in R$ thousand) 2025 2024 2023 2025 x 2024 2024 x 2023 Brazil Net sales 29,687,978 30,217,819 31,195,557 (1.8) % (3.1) % Cost of sales (27,807,111) (26,319,344) (27,593,565) 5.7 % (4.6) % Gross profit 1,880,867 3,898,475 3,601,992 (51.8) % 8.2 % Gross margin 6.3 % 12.9 % 11.5 % North America Net sales 35,787,268 31,931,433 33,179,048 12.1 % (3.8) % Cost of sales (30,299,734) (27,434,949) (26,629,584) 10.4 % 3.0 % Gross profit 5,487,534 4,496,484 6,549,465 22.0 % (31.3) % Gross margin 15.3 % 14.1 % 19.7 % South America Net sales 5,561,450 5,758,695 5,118,150 (3.4) % 12.5 % Cost of sales (4,964,009) (4,930,715) (4,014,010) 0.7 % 22.8 % Gross profit 597,441 827,980 1,104,140 (27.8) % (25.0) % Gross margin 10.7 % 14.4 % 21.6 % Elimination and adjustments Net sales (1,178,164) (881,291) (576,309) 33.7 % 52.9 % Cost of sales 1,179,815 861,592 653,167 36.9 % 31.9 % Gross profit 1,651 (19,699) 76,858 (108.4) % (125.6) % Gross margin (0.1) % 2.2 % (13.3) % Total Net sales 69,858,532 67,026,656 68,916,447 4.2 % (2.7) % Cost of sales (61,891,039) (57,823,416) (57,583,992) 7.0 % 0.4 % Gross profit 7,967,493 9,203,240 11,332,455 (13.4) % (18.8) % Gross margin 11.4 % 13.7 % 16.4 % (*) The information does not include data from joint ventures and associate companies. In 2025, Gerdau's cost of goods sold totaled R$61.9 billion, 7.0% higher than in 2024. Cost of goods sold per tonne increased 1.1%, driven by the U.S. dollar appreciation against the Brazilian real (+3.6%) and costs recorded throughout the year in Brazil’s operations, as explained above. These effects were partially mitigated by productivity gains and operational efficiency recorded in operations. In 2024, Gerdau’s cost of sales reached R$ 57.8 billion, stable comparing with 2023, to R$ 57.6 billion, impacted by the depreciation of the real against the dollar in the conversion of costs from foreign Segments, being offset by initiatives to reduce fixed costs and expenses, as well as asset optimization to boost the Company’s operational performance, mainly in Brazil, throughout 2024. In Brazil Segment in 2025, the cost of goods sold came 5.7% higher in 2025 versus 2024, driven by increased shipment volume and, mainly, by scheduled shutdowns and structural and operational adjustments necessary throughout the year to implement improvements and prepare for new investments at the Ouro Branco industrial unit. In Brazil Segment in 2024, the cost of sales decreased 4.6% compared to 2023, reflecting initiatives to reduce fixed costs and the continue increase in efficiency at the units in Brazil. However, this movement was offset by the increase in the price of some raw materials such as iron ore and pig iron. 58 Table of Contents In North America Segment in 2025, cost of goods sold in 2025 was 10.4% higher than in 2024 reflecting increased volumes. The cost per tonne in U.S. dollars was 2.8% lower, driven by higher capacity utilization, ongoing efforts to control fixed costs and productivity gains, and stable prices for raw materials such as scrap. In the North America Segment in 2024, the cost of sales increased 3.0% compared to 2023, due to the effect of exchange rate variation in the period, which offset the drop in the price of scrap. In South America Segment, the cost of goods sold remained stable, decreasing 0.7% in 2025 compared to 2024, despite increased shipment volumes, mainly driven by inflation adjustments and improved operational performance due to higher asset utilization rate, especially in Argentina. In the South America Segment in 2024, the cost of sales increased 22.8% compared to 2023, reflecting the effects of exchange rate and lower fixed costs dilution.

Impairment of assets In the fourth quarter of 2025, due to the revision of the Capex investment plan for its industrial plants, representing a significant reduction compared to recent years, the level of asset utilization at certain industrial plants in the Brazil segment, and the expectation of a deterioration in economic conditions to a greater extent than that contemplated in previous period scenarios, tests performed on other long-lived assets identified impairment losses in fixed assets of the Brazil segment amounting to R$ 1,591,369 as compared to R$ 199,627 on December 31, 2024, resulting from recoverable value below the carrying amount. Also, in December 2025, the Company assessed the recoverability of goodwill in its business segments. The analyses carried out identified impairment losses in the Brazil segment in the amount of R$ 1,964,504. Therefore, the Company wrote off the entire goodwill of this segment in the amount of R$ 373,135. No impairment losses were identified in 2024 and 2023. Income before Financial Income (Expenses) and Taxes Income before financial income (expenses) and taxes was R$ 3,739 million in 2025, compared to income of R$ 7,487 million in 2024. The reduction in 2025, when compared to 2024, was mainly related to the decrease in gross profit, which was related to higher cost of sales in 2025. Income before financial income (expenses) and taxes was R$ 7,487 million in 2024, compared to income of R$ 10,453 million in 2023. The reduction in 2024, when compared to 2023, was mainly related to the decrease in gross profit, which was related to lower demand and sales in 2024.

In 2024, the financial result was negative by R$ 2,0 billion, 82.9% higher than 2023, mainly due to the depreciation of the real against the dollar and other currencies in the countries where Gerdau operates, as well as inflation adjustments on non-monetary items of subsidiaries in Argentina. Additionally, the reduction in financial income is explained by the lower cash position of the portion denominated in reais in 2024, reducing returns on financial investments. Income and Social Contribution Taxes Income tax and social contribution was an expense of R$ 1,106 million in 2025 compared to an expense of R$ 865 million in 2024. This increase in the expense is mainly related to the reduction in deferred income and social contribution taxes, which more than compensated the reduction of 3.5% in the current income and social contribution taxes expenses for the year of 2025, when compared to 2024. Income tax and social contribution was an expense of R$ 865 million in 2024 compared to an expense of R$ 1,810 million in 2023. This decrease in the expense is mainly related to the reduction in income before taxes, which resulted in a reduction of 52.2% in the current income and social contribution taxes expenses for the year of 2024, when compared to 2023. Net Income Net income of R$ 1.4 billion in 2025 was 69.2% lower than 2024, mainly related to the lower operational results, as well as the variation in the financial result. Net income of R$ 4.6 billion in 2024 was 39.0% lower than 2023, mainly related to the lower operational results, as well as the variation in the financial result. B.

operating activities was R$ 8.0 billion, 29.8% lower compared to 2024, mainly reflecting lower operational results and the high basis for comparison, as in 2024 the Company received nearly R$1.8 billion related to the judicial deposit from the case regarding the exclusion of ICMS tax from the PIS and COFINS calculation basis. In 2024, net cash from operating activities was R$ 11.4 billion, 2.2% higher compared to 2023. Despite a lower net income for the year, the net cash from operating was partially compensated by income taxes and tax credit recovery. Cash conversion cycle In December 2025, the cash conversion cycle (working capital divided by net revenue for the quarter) decreased to 77 days, compared to 85 days in December 2024, representing a reduction of 8 days compared to 2024. This was influenced by the Company’s efforts to optimize inventories, mainly raw materials, as well as the devaluation of the dollar against the real during the period. In December 2024, the cash conversion cycle was 85 days compared to 87 days in December 2023, reflecting higher net sales in 2024. Net cash used in investing activities Net cash used in investing activities increased in 2025 when compared to 2024, mainly due to higher capex expenditure in 2025 and the higher proceeds from sales of property, plant and equipment, investments, and other in 2024. Net cash used in investing activities decreased in 2024 when compared to 2023, mainly due to proceeds from sales of property, plant and equipment, investments, and other. Net cash used in financing activities Net cash used in financing activities decreased in 2025 compared to 2024, reflecting funds raised throughout the year (debentures, bonds, and bilateral loans with first-tier institutions) aimed at reinforcing cash and extending debt average maturity. These effects were partially offset by loan repayments during the period. Net cash used in financing activities decreased in 2024 compared to 2023, mainly due to proceeds from loans and financing related to the issuance of debentures aimed at reprofiling short-term debts with higher rates, as well as to lengthen the Company’s debt profile. This effect partially offset the net cash used for treasury share purchases, in line with the Buyback Program announced by the Company on July 31, 2024. Indebtedness The Company’s debt is used to finance investments in fixed assets, including the modernization and technological upgrade of its plants and the expansion of installed capacity, as well as for working capital, acquisitions and, depending on market conditions, short-term financial investments. (1) Working capital: trade accounts receivable, plus inventories, less suppliers (based on the balance of each account at the end of the year). (2) Cash conversion cycle: working capital, divided by net sales (of the last three months as of the date presented), multiplied by 90. 62 Table of Contents The following table profiles the Company’s debt and debentures as of the years ended December 31, 2025, 2024 and 2023 (in thousands of Brazilian reais): 2025 2024 2023 CURRENT: 941,904 735,737 1,797,622 Short-term debt 897,295 697,049 1,783,201 Debentures 44,609 37,988 14,421 NON-CURRENT: 13,240,247 12,901,447 9,095,686 Long-term debt 8,877,457 9,110,972 8,296,474 Debentures 4,362,790 3,790,475 799,212 TOTAL DEBT: 14,182,151 13,636,484 10,893,308 Total cash and cash equivalents and short-term investments 6,374,797 8,276,843 5,343,742 Brazil 1,019,968 2,234,748 2,618,434 Companies abroad 5,354,829 6,042,095 2,725,308 NET DEBT (1) 7,807,354 5,359,641 5,549,566 (1) The calculation of net debt is made by subtracting cash and cash equivalents and short-term investments from total debt. Net debt is not a GAAP measure recognized under IFRS Accounting Standards and should not be considered in isolation from other financial measures. Other companies may calculate net debt differently and therefore this presentation of net debt may not be comparable to other similarly titled measures used by other companies. The Company uses “net debt” as indicator of indebtedness in its financial management. Total debt was R$ 14,182 million, R$ 13,636 million and R$10,893 million for the years ended December 31, 2025, 2024 and 2023, respectively. At the end of December 2025, the nominal weighted average cost of gross debt was CDI – 0.21% for the portion denominated in Brazilian real and 6.12% for the portion denominated in U.S. dollar. On December 31, 2025, the average gross debt term was 8.5 years, with the debt maturity schedule well balanced and well distributed over the coming years. Gerdau S.A.

On December 31, 2025, the outstanding balance of these debentures was as follows: Outstanding Interest Payment Initial Amount Principal Debenture Issuance Date Due Date Months Coupon (R$ million) (R$ million) 2028 December 10th, 2024 December 10th, 2028 June & December CDI + 0.50% 1,500 1,500 2029 May 29th, 2024 May 29th, 2029 May & November CDI + 0.60% 1,500 1,500 2032 June 04th, 2025 June 04th, 2032 June & December CDI + 0.65% 1,375 1,375 TOTAL 4,375 Other Financial Agreements The Company and its subsidiaries maintain other financing contracts, mainly bilateral bank loans. On December 31, 2025, the outstanding balance of these loans was R$ 2,261 million. See Note 15 - Short-Term Debt and Long-Term Debt in its Consolidated Financial Statements included herein for further details. Credit Lines In 2022, the Company concluded the roll-over of its senior unsecured working capital revolving facility with a total committed amount of US$ 875 million (equivalent to R$ 4,815 million) and final maturity in September 2027. On December 31, 2025, there were no outstanding loans under this facility. Exchange Rate The Company has designated a portion of its debt denominated in foreign currency and contracted by companies in Brazil as a hedge for a portion of the net investments in foreign subsidiaries. As a result, the effects from exchange variation gains or losses on the portion of debt designated for hedge accounting are also recognized in shareholders’ equity, in accordance with IFRS Accounting Standards. The subsidiaries that issued the debt are not subject to income taxes and as such there is no income tax effect on the exchange gains and losses on the debt. However, the subsidiaries have loaned the proceeds to other entities in Brazil with terms identical to those of the Ten - Year Bonds. The payable by the subsidiaries in Brazil to the foreign subsidiaries denominated in US dollars generates exchange gains (losses) that are taxable and results in income tax recognized in the income statement, while these exchange variances are eliminated in consolidation with the offsetting exchange gains (losses) recognized by the foreign subsidiaries. Starting from April 1, 2012, with the objective of eliminating the tax effect from the exchange variance of these debts, the Company designated part of its debt in foreign currency as a hedge for a portion of the investments in subsidiaries located outside Brazil. As a result, the effect of exchange rate changes on these debts in the amount of US$ 0.8 billion (equivalent to R$ 4.6 billion on December 31, 2025) (designated as a hedge) has been recognized in the Statement of Comprehensive Income. Derivatives Risk management objectives and strategies: The Company understands that it is subject to different market risks, such as fluctuations in exchange rates, interest rates and commodity prices. In order to carry out its strategy for profitable growth, the Company implements risk management strategies with the objective of mitigating such market risks. 64 Table of Contents The Company’s objective when entering into derivative transactions is always related to mitigation of market risks as stated in our policies and guidelines. All outstanding derivative financial instruments are monthly reviewed by the Finance Committee, which validates the fair value of such financial instruments. All gains and losses in derivative financial instruments are recognized by its fair value in the Consolidated Financial Statements of the Company. Policy for use of derivatives: according to internal policy, the financial result must arise from the generation of cash from its business and not gains from the financial market. The Company uses derivatives and other financial instruments to reduce the impact of market risks on its financial assets and liabilities or future cash flows and earnings. Gerdau has established policies to assess market risks and to approve the use of derivative financial instruments transactions related to those risks. The Company enters into derivative financial instruments to manage the above-mentioned market risks and never for speculative purposes. Policy for determining fair value: the fair value of the derivative financial instruments is determined using models and other valuation techniques, which involve future prices and curves discounted to present value as of the calculation date. Amounts are gross before taxes. Due to changes in market rates, these amounts can change up to the maturity or in situations of early settlement of transactions. The derivative financial instruments may include: interest rate swaps, cross currency/commodities swaps, currency options contracts and currency/commodities forward contracts. Dollar forward contracts: the Company entered into NDF operations (Non Deliverable Forward) in order to mitigate the foreign exchange risk on assets and liabilities denominated in foreign currencies, mainly U.S. dollar. The counterparties of these transactions are financial institutions with low credit risk. 65 Table of Contents The effects of financial instruments are classified as follow: Notional value Amount receivable Amount payable Contracts Position 2025 2024 2023 2025 2024 2023 2025 2024 2023 Currency forward contracts Maturity in 2024 buyed in US$ — — US$ 34,2 million — — — — — 17,337 Commodity derivatives Maturity in 2024 buyed in US$ — — US$ 12,1 million — — 32 — — 1,349 Maturity in 2025 buyed in US$ US$ 1,1 million US$ 4,3 million — — — — — 1,747 — Commodity contracts Maturity in 2026 — — — — 20,113 16,921 — — — — Swaps IPCA x DI Maturity in 2024 — — — R$ 450.0 million — — 734 — — 356 Maturity in 2026 CDI –1.10% R$ 300 million — — — — — 2,192 — — Maturity in 2026 CDI –0.90% R$ 150 million — — — — — 1,114 — — Swaps USD x DI Maturity in 2026 107.9% CDI US$ 30.6 million US$ 30.6 million US$ 30.6 million 16,510 35,947 — — — 1,606 Total fair value of financial instruments 36,623 52,868 766 3,306 1,747 20,648 Fair value of derivatives 2025 2024 2023 Current assets 36,623 16,921 766 Non-current assets — 35,947 — 36,623 52,868 766 Fair value of derivatives Current liabilities 3,306 1,747 19,042 Non-current liabilities — — 1,606 3,306 1,747 20,648 Net Income 2025 2024 2023 Gains on financial instruments 22,107 86,743 39,895 Losses on financial instruments (67,733) (263,644) (54,874) (45,626) (176,901) (14,979) Other comprehensive income Gains on financial instruments — — 783 Losses on financial instruments — (783) — — (783) 783 Capital Expenditures 2025 – Capital Expenditures In fiscal year 2025, capital expenditure on fixed assets was R$ 6.1 billion.

All Gerdau mills have a Quality Management System supported by a wide array of quality control tools. Product development projects are headed by specialists who use quality tools such as “Six Sigma”, a set of statistical methods for improving the assessment of process variables, and the concept of “Quality Function Deployment”, a methodology through which technicians can identify and implement the customer requirements. Given this level of quality management, mills are ISO 9001 or ISO TS 16949 certified. In general, production, technical services and quality teams are responsible for developing new products to meet customer and market needs. Gerdau uses a Quality Management System developed in house that applies tests for product design, manufacturing processes and final-product specifications. A specially trained team and modern technologies also exist to assure the manufactured product high standards of quality. Gerdau’s technical specialists do planned visits, some are randomly selected, and some are scheduled visits, to its customers to check on the quality of the delivered products in order to seek the final user satisfaction for products purchased indirectly. Due to the specialized nature of its business, the Gerdau special steel mills are constantly investing in technological upgrading and in research and development. These mills are active in the automotive segment and maintain a technology department (Research and Development) responsible for new products and the optimization of existing processes. International machinery manufacturers and steel technology companies supply most of the sophisticated production equipment that Gerdau uses. These suppliers generally sign technology transfer agreements with the purchaser and provide extensive technical support and staff training for the installation and commissioning of the equipment. Gerdau has technology transfer and benchmarking agreements with worldwide recognized performance companies. As is common with mini mill steelmakers, Gerdau usually acquires technology in the market rather than develops new technology through intensive process research and development, since steelmaking technology is readily available for purchase. The Company is not dependent on patents or licenses or new manufacturing processes that are material to its business. See item “Information on the Extent of the Company’s Dependence” for further details. 67 Table of Contents D. TREND INFORMATION In 2025, Gerdau produced 12.1 million tonnes of steel, an increase of 3.6% more compared to 2024. Gerdau’s shipments reached 11.6 million tonnes, generating net sales of R$ 69.9 billion, 4.2% lower than in 2024. All Gerdau operations take place in the Americas. For 2026, Gerdau’s perspectives remain positive, mainly in the U.S., where demand has a positive trend in the solar energy, data centers, and infrastructure sectors, with customers reporting healthy backlog levels. However, the automotive sector continues to face more challenging dynamics, impacting the special steel segment. Additionally, the Company will closely monitor new developments in Section 232 tariffs and USMCA negotiations. In Brazil, moderate growth in demand is expected, in line with the IABR, with emphasis on infrastructure and civil construction. Nevertheless, the Company remains vigilant on the automotive sector, which may be impacted by a prolonged high-interest rate environment and the inflow of imported vehicles. The Company continues to invest in modernization and technology updates at its units, aiming to constantly improve the profitability and productivity of its assets. The use of technological enablers such as analytics, AI, and digital twins is also being considered by management, due to its potential for greater operational efficiency. Additionally, Gerdau remains focused on identifying opportunities for cost reduction across all units. E. CRITICAL ACCOUNTING ESTIMATES Critical accounting estimates are those that require ‘management’s most difficult, subjective or complex judgments, often as a result of the need to make estimates that impact matters that are inherently uncertain. As the number of estimates and assumptions affecting the possible future resolution of the uncertainties increases, those judgments become even more subjective and complex. In the preparation of the Consolidated Financial Statements, the Company has relied on estimates and assumptions derived from historical experience and various other factors that it deems reasonable and significant. Although these estimates and assumptions are reviewed by the Company in the normal course of business, the presentation of its financial position and results of operations often requires making judgments regarding the effects of inherently uncertain matters on the carrying value of its assets and liabilities. Actual results may differ from estimates based on different variables, assumptions or conditions. In order to provide an understanding of how the Company forms its judgments about future events, including the variables and assumptions underlying the estimates, the Company presents below the subjects that demand critical accounting estimates: ● revenue recognition; ● the recoverable amount of goodwill and long-lived assets; ● provisions for tax, civil and labor claims; ● recoverability of deferred tax assets; ● estimates in selecting interest rates, return on assets, mortality tables and expectations for salary increases; and ● long-term incentive plans through the selection of the valuation model and rates. Revenue recognition Net sales are presented net of taxes and discounts. The significant judgment made by the Company is presented in Note 2.17 and regarding revenue recognition it considers that such recognition is derived from the sole performance obligation to transfer its products or services in accordance with contracts and commercial agreements. The transfer of control and the fulfillment of the Company’s performance obligation occur at the same time, at which time the revenue of sale of goods and services is recognized by the Company. It is also considered that the buyer obtains the benefits of the acquisitions, the potential cash flows, and the amount of revenue (transaction price) can be reliably measured, and the consideration must be transferred, meaning that the Company is likely to receive the consideration to which it is entitled in exchange for the products or services. 68 Table of Contents For the Company’s operations, generally the revenue recognition criteria are met when its products are delivered to its customers (CIF term) or to a carrier that will transport the goods to its customers (FOB term) and these are the times when the Company has generally fulfilled its performance obligations. Revenue is measured by the transaction price of the consideration received or receivable, an amount to which the Company expects to be entitled. The Company’s products follow industry production standards for its applications. Historically, only a small portion of the Company’s products are returned or have claims filed against the sale as result of quality complaints or other problems. Claims may be one of the following: product shipped and billed to an end customer that did not meet industry quality standards, such as physical defects in the goods, goods shipped to the wrong location or goods shipped outside acceptable time parameters. The Company estimates the consideration for such claims and reduces the amount of revenue recognized. The warranties and claims arise when the product fails on the criteria mentioned above. Sales-related warranties associated with the goods cannot be purchased separately and they serve as an assurance that the products sold comply with agreed specifications. Accordingly, the Company accounts for warranties in accordance with IAS 37. Warranties and claims represent immaterial amounts to the Company. The recoverable amount of goodwill and long-lived assets At each balance sheet date, the Company performs an assessment to determine whether there is evidence that the carrying amount of long-lived assets might be impaired. If such evidence is identified, the recoverable amount of the assets is estimated by the Company. The recoverable amount of an asset is determined as the higher of: (a) its fair value less estimated costs to selling and (b) its value in use. The value in use is measured based on discounted cash flows (before taxes) derived from the continuous use of the asset until the end of its estimated useful life. Regardless of whether or not there is any indication that the carrying amount of the asset may be impaired, the balances of goodwill arising from business combinations and intangible assets with indefinite useful lives are tested for impairment at least once a year in December. When the carrying amount of the asset exceeds its recoverable amount, the Company recognizes a reduction in the book value of the asset (Impairment). The reduction to the recoverable amount of the asset is recorded as an expense. Goodwill impairment, after recognized, is not allowed to be reversed, even if circumstances that resulted in the impairment changes. Other assets impairment may be reversed if circumstances that resulted in the impairment no longer exists, but in these circumstances the reversal of impairment is limited to the residual depreciated balance of the asset at the time of the reversal, determined as if the impairment had not been recorded. If actual results are not consistent with estimates and assumptions used in estimating future cash flows and asset fair values, the Company may be exposed to losses that could be material. The Company performs tests for impairment of assets, notably goodwill and other long-lived assets, based on projections of discounted cash flows, which take into account assumptions such as: cost of capital, growth rate and adjustments applied to flows in perpetuity, methodology for working capital determination, investment plans, and long-term economic-financial forecasts. The impairment test of these assets are assessed based on the analysis of facts or circumstances that may indicate the need to perform the impairment test and are performed at least annually, for groups of cash generating units containing goodwill, in December, or whenever changes in events or circumstances indicate that the goodwill and other long-lived assets may be impaired. To determine the recoverable amount of each cash generating unit, the Company uses the discounted cash flow method, using as basis, financial and economic projections for each one. The projections are prepared by taking into consideration observed changes in the economic scenario in the market where the Company operates, as well as assumptions with respect to future results and the historical profitability of each segment. The Company maintains its monitoring of the steel market in order to identify any deterioration, significant drop in demand from steel consuming sectors (notably automotive and construction), stoppage of industrial plants or significant changes in the economy or financial market that result in increased perception of risk or reduction of liquidity and refinancing capacity. 69 Table of Contents Goodwill impairment test The Company has three operating segments, which represents the lowest level in which goodwill is monitored by the Company. Goodwill balances by business segment are presented in Note 11 of the Consolidated Financial Statements contained herein. In December 2025, the Company assessed the recoverability of goodwill in its business segments. The analyses carried out identified impairment losses in the Brazil segment in the amount of R$ 1,964,504. Therefore, the Company wrote off the entire goodwill of this segment in the amount of R$ 373,135, while the remaining portion of R$ 1,591,369 was recognized in fixed assets. No impairment losses were identified in 2024 and 2023. The period for projecting the cash flows for the goodwill impairment test was five years. The assumptions used to determine the value in use based on the discounted cash flow method include analysis prepared in dollars, such as: projected cash flows based on management estimates for future cash flows, exchange rates, discount rates and growth rates. The cash flow projections already reflect a competitive scenario, as well as macroeconomic challenges in some geographies in which the Company operates. The perpetuity was calculated considering stable operating margins, levels of working capital and investments. The perpetuity growth rates considered in the fourth quarter of 2024 test were: a) North America: 3% (3% in December 2024); b) South America: 3% (3% in December 2024); and c) Brazil: 3% (3% in December 2024). The post-tax discount rates used were determined taking into consideration market information available on the date of performing the impairment test. The Company adopted distinct rates for each business segment tested with the purpose of reflecting the differences among the markets in which each segment operates, as well as the risks associated to each of them. The post-tax discount rates used were: a) North America: 10.75% (10.50% in December 2024); b) South America: 13.25% (14.75% in December 2024); and c) Brazil 11.75% (11.75% in December 2024). As required by the accounting standard, the Company made a calculation to determine the discount rates, before income tax and social contribution (gross rate of tax effects) and this calculation resulted in the following discount rates for each segment: a) North America 13.46% (13.28% in December 2024); b) South America: 19.04% (22.14% in December 2024); and c) Brazil: 14.68% (15.16% in December 2024). Discounted cash flows are compared to the book value of each segment and result in the recoverable amount that exceeded book value as shown below: a) North America: R$ 9,584 million (R$ 5,824 million in 2024); and b) South America: R$ 913 million (R$ 1,435 million in 2024). In the Brazil segment, the recoverable amount was below the carrying amount by R$ 1,965 million (exceeded the carrying amount by R$ 5,293 million in 2024). The Company performed a sensitivity analysis in the assumptions of discount rate and perpetuity growth rate, due to the potential impact in the discounted cash flows. An increase of 0.5 percentage points in the discount rate of each segment’s cash flow would result in a recoverable amount that exceeded book value as shown below: a) North America: R$ 7,465 million (R$ 3,642 million in 2024) and b) South America: R$ 724 million (R$ 1,247 million in 2024). In the Brazil segment, the recoverable amount would be below the book value by R$ 3,456 million (it would exceed the book value by R$ 3,424 million in 2024). On the other hand, a decrease of 0.5 percentage points in the perpetuity growth rate of the cash flow of each business segment would result in a recoverable amount that exceeded book value as shown below: a) North America: R$ 8,046 million (R$ 4,220 million in 2024) and b) South America: R$ 790 million (R$ 1,326 million in 2024). In the Brazil segment, the recoverable amount would be below the book value by R$ 3,008 million (it would exceed the book value by R$ 3,962 million in 2024). 70 Table of Contents It is important to note that significant events or changes in the outlook may lead to losses due to goodwill recoverability. A combination of the above-mentioned sensitivities in the cash flow of each segment would result in an impairment value exceeding the book value as shown below: a) North America: R$ 6,130 million (R$ 2,255 million in 2024) and b) South America: R$ 614 million (R$ 1,149 million in 2024). In the Brazil segment, the recoverable amount would be below the book value by R$ 4,374 million (it would exceed the book value by R$ 2,253 million in 2024). Other assets impairment test In the fourth quarter of 2025, due to the revision of the Capex investment plan for its industrial plants, representing a significant reduction compared to recent years, the level of asset utilization at certain industrial plants in the Brazil segment, and the expectation of a deterioration in economic conditions to a greater extent than that contemplated in previous period scenarios, tests performed on other long-lived assets identified impairment losses in fixed assets of the Brazil segment amounting to R$ 1,591,369 (R$ 199,627 in 2024), resulting from recoverable value below the carrying amount. These losses were determined based on the difference between the carrying amount of assets and its recoverable amount, which represents their value in use (the greater of the fair value less disposal expenses or their value in use). These losses were recorded as an expense, in the “Impairment of assets” line in the Consolidated Statements of Income. The post-tax discount rates used for this test are the same as presented in Note 29.1 of the goodwill impairment test on the Consolidated Financial Statements contained herein. The Company will maintain over the next year its constant monitoring of the steel market in order to identify any deterioration, significant drop in demand from steel consuming sectors (notably automotive and construction), stoppage of industrial plants or activities significant changes in the economy or financial market that result in increased perception of risk or reduction of liquidity and refinancing capacity. Although the projections made by the Company provide a more challenging scenario than that in recent years, the events mentioned above, if manifested in a greater intensity than that anticipated in the assumptions made by management, may lead the Company to revise its projections of value in use and eventually result in impairment losses. Provisions for tax, civil and labor claims The significant judgment is related to recognition and measurement of provisions. Information regarding provisions for tax, civil and labor liabilities is presented in Note 19 of the Consolidated Financial Statements contained herein. The Company recognizes provisions for liabilities and probable losses that have been incurred when it has a present obligation as a result of past events, it is probable that the Company will be required to settle the obligation and a reliable estimate of the amount of the obligation can be made. If the effect of the time value of money is material, provisions are discounted using a current pre-tax rate that reflects, where appropriate, the risks specific to the liability. The table below informs amounts of tax, labor and civil provisions: 2025 2024 a) Tax provisions 1,928,918 1,925,237 b) Labor provisions 326,315 369,041 c) Civil provisions 37,179 34,571 2,292,412 2,328,849 a) Tax Provisions Tax provisions refer mainly to disputes related to ICMS, IPI, Income tax and social contribution, social security contributions, offsetting of PIS and COFINS credits and incidence of PIS and COFINS on other revenues. b) Labor Provisions The Company is party to a group of individual and collective labor and/or administrative lawsuits involving various labor amounts and the provision arises from unfavorable decisions and/or the probability of loss in the ordinary course of proceedings with the expectation of outflow of financial resources by the Company. c) Civil Provisions The Company is party to a group of civil, arbitration and/or administrative lawsuits involving various claims and the provision arises from unfavorable decisions and/or probable losses in the ordinary course of proceedings with the expectation of outflow of financial resources for the Company. 71 Table of Contents Recoverability of Deferred Tax Assets The amount of the deferred income and social contribution tax asset is revised at each Consolidated Financial Statement date and reduced by the amount that is no longer probable of being realized based on future taxable income. Deferred income and social contribution tax assets and liabilities are calculated using tax rates applicable to taxable income in the years in which those temporary differences are expected to be realized. Future taxable income may be higher or lower than estimates made when determining whether it is necessary to record a tax asset and the amount to be recorded. The realization of deferred tax assets for tax loss carryforwards are supported by projections of taxable income based on technical feasibility studies submitted annually to the Company’s Board of Directors. These studies consider historical profitability of the Company and its subsidiaries and expectation of continuous profitability and estimated the recovery of deferred tax assets over future years. The other tax credits arising from temporary differences, mainly tax contingencies, and provision for losses, were recognized according to their estimate of realization, and are consistent with recoverability described above. Due to the lack of expectation to use tax losses, negative social contribution base and deferred exchange variation arising from some operations in Brazil, the Company did not recognize a portion of tax assets of R$ 907,295 (R$ 300,763 on December 31, 2024), which do not have an expiration date. The subsidiaries abroad had R$ 701,413 (R$ 849,200 as of December 31, 2024) of tax credits on capital losses for which deferred tax assets have not been recognized and which expire between 2029 and 2035 and also several Unrecognized tax loss carryforwards from state credits in the United States in the amount of R$ 291,979 (R$ 326,966 as of December 31, 2024), which expire at various dates between 2025 and 2038. Estimates in selecting interest rates, return on assets, mortality tables and expectations for salary increases Actuarial gains and losses are recorded in the period in which they are originated and are recorded in the statement of comprehensive income. The Company recognizes its obligations related to employee benefit plans and related costs, net of plan assets, in accordance with the following practices: ● The cost of pension and other post-employment benefits provided to employees is actuarially determined using the projected unit of credit method and management’s best estimate of expected investment performance for funded plans, salary increase, retirement age of employees and expected health care costs. The discount rate used for determining future benefit obligations is an estimate of the interest rate in effect at the balance sheet date on high-quality fixed-income investments with maturities that match the expected maturity of obligations. ● Pension plan assets are stated at fair value. ● Gain and losses related to the curtailment and settlement of the defined benefit plans are recognized when the curtailment or settlement occurs, and they are based on actuarial evaluation done by independent actuaries. In accounting for pension and post-retirement benefits, several statistical and other factors that attempt to anticipate future events are used to calculate plan expenses and liabilities. These factors include discount rate assumptions, return on plan assets, future increases in health care costs, and rate of future compensation increases. In addition, actuarial computations include other factors whose measurement involves judgment such as withdrawal, turnover, and mortality rates. The actuarial assumptions used by the Company may differ materially from actual results in future periods due to changing market and economic conditions, regulatory events, judicial rulings, higher or lower withdrawal rates, or longer or shorter participant life spans. 72 Table of Contents The tables below show a summary of the assumptions used to calculate the defined benefit plans in 2025 and 2024, respectively: 2025 Brazilian Plan North American Plan Average discount rate 11.15% 4.75% to 5.42% Rate of increase in compensation Not applicable Not applicable Mortality table AT-2000 per sex RP-2012 and MP-2017&2021 Mortality table of disabled AT-2000 per sex Not applicable Rate of rotation Null Based on age and/or the service 2024 Brazilian Plan North American Plan Average discount rate 11.07% 4.58% to 5.62% Rate of increase in compensation Not applicable 3.00% Mortality table AT-2000 per sex RP-2006 and MP-2024 Mortality table of disabled AT-2000 per sex RP-2006 and MP-2024 Rate of rotation Null Based on age and/or the service Quantitative information regarding pension and post-retirement benefits amounts recognized are presented in Note 21 of the Consolidated Financial Statements contained herein.
