Loma Negra Compania Industrialargentina Sociedad Anonima
A maker of cement, concrete, and lime, Loma Negra is Argentina's largest cement producer, supplying the construction materials that go into buildings, roads, and infrastructure across the country. It was founded in 1926, when Argentine businessman Alfredo Fortabat discovered rich limestone deposits on his estancia south of Olavarría and built his first plant right there. The name means "black hill," taken from the small pampas hamlet where the factory stands.

We are exposed to market risks arising from our normal business activities. These market risks principally involve the possibility that changes in interest rate or exchange rates will adversely affect the value of our financial assets and liabilities or future cash flows and earnings. Liquidity risk is the risk of us not complying with all of our obligations as a result of a decrease in the fair value of our investments, an excessive concentration of liabilities from a particular source, the mismatch between assets and liabilities, the lack of liquidity of assets or the funding of long term assets with short-term liabilities, among other possible risks. We could enter into derivatives and other financial instruments for purposes other than trading, in order to manage and reduce the impact of fluctuations in foreign currency exchange rates. These instruments are intended to reduce the impacts of any devaluation of the peso against the U.S. dollar and any increase in international interest rates on U.S. dollar liabilities. Interest Rate Risk We are exposed to interest rate risk because a significant portion of our indebtedness bears interest at floating rates. As of December 31, 2025, our total outstanding borrowings on a consolidated basis was Ps. 297,908 million, where 15% of the company's consolidated loans accrued interest at a variable rate. In the event that the average floating rate applicable to our financial liabilities during the year ended December 31, 2025 were 1.0% higher than the average interest rate during such period, our financial expenses in the same period would have increased by Ps. 455 million. Foreign Currency Exchange Rate Risk Our liabilities that are exposed to foreign currency exchange rate risk are denominated in U.S. dollars. To partially offset our risk of any depreciation of the peso against the U.S. dollar, from time to time we may enter into derivative or dollar linked contracts. Because we borrow in U.S. dollars in international or local markets to fund our operations and investments, we are exposed to market risks from changes in foreign exchange rates and interest rates. Our foreign currency exposure gives rise to market risks associated with exchange rate movements. A significant portion of our borrowings are denominated in foreign currency. As of December 31, 2025, our consolidated foreign currency-denominated borrowings was Ps. 253,981 million, denominated in U.S. dollars. As of December 31, 2025 we did not have foreign currency derivative financial instruments. In the event that the peso was to depreciate by 25% against the U.S. dollar as compared to the peso/U.S. dollar exchange rate as of December 31, 2025, our foreign currency denominated indebtedness as of December 31, 2025 would have increased by Ps. 66,093 million. 137 Table of Contents Additionally, considering the exchange regulations and restrictions currently applicable in Argentina, the Group constantly monitors the alternatives for collecting assets and settling liabilities in foreign currency and the related impact. The gain/loss arising from the use of financial instruments to settle transactions in foreign currency is recognized when the Group unconditionally commits to or irreversibly executes such settlement. As of December 31, 2025, the use of financial instruments to settle the above transactions would result in an impact of approximately 1.5%. Liquidity Risk Our board of directors has the ultimate responsibility for liquidity risk management and has established an appropriate framework allowing our management to handle financing requirements for the short-, medium-and long-term. We manage liquidity risk by maintaining reserves, obtaining loan facilities, continuously monitoring projected and real cash flows, and reconciling maturity profiles of financial assets and liabilities. We consider that the liquidity risk exposure is low since we have been generating cash flow from our operating activities, supported on strong profits and have access to loans and financial resources. However, if we are unable to access the capital markets to finance our operations in the future, this could adversely affect our ability to obtain additional capital to grow our business. See “Item 3.D. Key Information—Risk Factors—Risks Relating to Our Business and Industry—Management’s plans to obtain sufficient funds to settle current liabilities may not be accomplished and hence we may have negative working capital in the near future”.

A.[Reserved] B.Capitalization and Indebtedness Not applicable. C.Reasons for the Offer and Use of Proceeds Not applicable. D.Risk Factors Our business faces significant risks. You should consider carefully the risks described below and all other information contained in this annual report. If any of the following risks were to occur, our business, financial condition and results of operations would likely be materially adversely affected. In that event, the trading price of our ordinary shares or American Depositary Shares, or ADSs, would likely decline and you might lose all or part of your investment. The following risks are not the only risks that we face; we are subject to various risks mainly resulting from changing economic, environmental, political, industry, business, financial and climate conditions. Our results could materially differ from those anticipated in these forward-looking statements, as a result of certain factors including the risks described below and elsewhere in this annual report and our other SEC filings. See also “Cautionary Statement with Respect to Forward-Looking Statements and Risk Factors Summary”. For purposes of this section, the indication that a risk, uncertainty or problem may or will have a “material adverse effect on us” or that we may experience a “material adverse effect” means that the risk, uncertainty or problem could have a material adverse effect on our business, financial condition or results of operations and/or the market price of our ordinary shares or ADSs, except as otherwise indicated or as the context may otherwise require. You should view similar expressions in this section as having a similar meaning. Risks Relating to Argentina Most of our operations, property and customers are located in Argentina and a portion of our liabilities and assets are denominated in foreign currency. Consequently, the quality of our assets, property status and our results of operations depend on the macroeconomics, regulatory, social and political conditions of Argentina and on the exchange 1 Table of Contents rates between the peso and foreign currencies, in particular, the U.S. dollar. These conditions include growth rates, inflation rates, exchange rates, taxes, foreign exchange controls, changes in the interest rates, changes in Argentine government policies, social instability and other domestic and international political and economic events that may take place in Argentina or may affect it. Investing in a developing economy such as Argentina entails certain inherent risks. Argentina is a developing economy and investing in such markets generally carries risks. These risks include political, social and economic instability that may affect Argentina’s economic condition. In the past, instability in Argentina was caused by many different factors, including the following: •aggravation of a financial crisis in several countries in the region; •abrupt changes in the monetary and fiscal policies of countries with prominent economies due to macroeconomic conditions; •increase in public expenses affecting the economy and fiscal deficits; •inconsistent fiscal and monetary policies; •uncertainty with respect to the Argentine public sector’s payment capacity and the potential for obtaining international financing; •low levels of investment; •changes in governmental economic or tax policies; •high levels of inflation; •abrupt changes in currency values; •high interest rates; •wage increases and price controls; •exchange and capital controls; •political and social unrest; •the growing effects of labor unions; •the significant price drop of main commodities exported by Argentina; •early termination of our public concession; •fluctuations in the BCRA reserves; •widespread illnesses or epidemics; and •restrictions on exports and imports. Any of the above factors either individually or taken together, could have material adverse effects on the Argentine economy and on our business, results of operations and financial condition. The Argentine economy has experienced extreme volatility in the recent decades, with uneven periods of economic growth, high inflation and devaluation of the peso against the U.S. dollar. Therefore, our business and operations may be affected by the economic and political events that may affect the Argentine economy, such as: price controls, foreign exchange controls, currency devaluations, high interest rates, increase in public expenses, tax increase or other regulatory initiatives that increase the Argentine government’s intervention in the economy. On September 1, 2019 the Argentine government reintroduced strong restrictions and exchange controls, which, among other things, significantly restricted access to the exchange markets by individuals and entities. Since then, these restrictions have been modified and, in some respects, eased, and those that remain effective as of the date of this annual report are described in “Item 10.-D Exchange Controls.” The Social Solidarity and Productive Reactivation Law No. 27,541, enacted in December 2019, and its regulatory Decree No. 99/2019 (the “Social Solidarity Law”), as amended from time to time, introduced important additional foreign exchange restrictions and tax modifications. 2 Table of Contents During 2021 there was a recovery of the economic activity (after the impact of COVID-19 in 2020) reflected in the 10.4% GDP growth, and this positive trend continued in 2022, with 5.0% GDP growth. Nevertheless, this trend reversed in 2023, when GDP contracted by 1.6%, followed by a decline of 1.3% in 2024, primarily driven by a significant reduction in public works and a contraction in private consumption. During 2025, the economy began to stabilize; according to the INDEC, for the fourth quarter of 2025, Argentina's GDP recorded a recovery of 4.4% for the full year, surpassing initial estimates as inflation began to decelerate and credit conditions improved. To contain the escalation of the currency exchange rate, the Argentine Central Bank has been selling its reserves of U.S. dollars, which has resulted in a decrease in the Argentine Central Bank’s international reserves from US$ 65.7 billion as of December 31, 2018, to US$ 23.1 billion as of December 31, 2023. Since Javier Milei took office in December 2023, the BCRA had bought approximately US$ 4,760 million by the end of March 2025. Throughout March and April 2025, growing tensions in the foreign exchange market compelled the central bank to sell reserves, just as the government approached the final stretch of negotiations with the IMF and other multilateral institutions. In the first days of Javier Milei's mandate, the new government launched a set of policies aimed to deregulate the economy to address the economic and social crisis. On December 20, 2023, through the Decree of Necessity and Urgency No. 70/2023, the Executive Branch declared the public emergency in economic, financial, fiscal, administrative, social security, tariff, sanitary and social matters until December 31, 2025. This regulation included numerous amendments and repeals of several laws. The measures include, but are not limited to, the repeal of regulations on housing rental contracts, the supply of essential products, the marketing of mass consumption products, the corporate form of companies where the State participation has been modified, among others. On December 27, 2023, the Executive Branch submitted to Congress the draft law titled "Bases and Points of Departure for the Freedom of the Argentine People" (the "Bases Law"). After months of negotiations, the Bases Law was finally approved on June 28, 2024. The key points of this approval are as follows: •Emergency: The declaration of a public emergency in economic, financial, tax, social security, security, defense, tariff, energy, health, administrative, and social matters. The declaration of emergency in the bill is to last until December 31, 2025, but it enables the Executive to extend such term for two more years. In terms of state reorganization, the Bases Law establishes the foundations for legislative delegations to the Executive, namely: i) improving the functioning of the state; ii) reducing the oversizing of the state structure; and iii) ensuring effective internal control in the national public administration. •Regime for Large Investments: The creation of the Regime for Large Investments ("RIGI"), which establishes a legal and regulatory framework to promote investment in productive projects in Argentina. •Labor Modernization: Various modifications to laws 24,013 (Employment), 20,744 (Labor Contract Law), and 26,727 (Agricultural Work). Moreover, Law 25,323 (Labor Compensation) is repealed. The amendments include the extension of the trial period or the exemption from penalties and criminal actions for those employers who have not made the corresponding contributions, in exchange for the regularization of the worker. •Concessions: The possibility for the government to grant public works concessions to private or public entities for the construction, maintenance, or exploitation of public works. •Various amendments to Laws 17,319 (Hydrocarbons), 24,076 (Natural Gas) and 26,741 (Fiscal Oilfields), including the repeal of Article 1 of Law 26,741, which declared the self-supply of hydrocarbons to be of public interest and a priority objective, and the creation of the National Gas and Electricity Regulatory Entity, replacing the Electricity Regulatory Entity (“ENRE”). •Tax Modernization: Various tax changes, including, but not limited to, changes in income tax, personal property tax, single taxation and incentives for money laundering. On April 16, 2024, the Supreme Court of Justice unanimously rejected two actions filed against Decree No. 70/2023, stating that neither of them presented the existence of a 'cause,' 'case,' or 'controversy' that falls under the jurisdiction of the Supreme Court to rule on. On July 12, 2024, Congress approved Law No. 27.743 on Palliative and Relevant Tax Measures ("Tax Package") regarding the regularization of tax, customs, and fiscal obligations, aimed at achieving voluntary payment by taxpayers and responsible parties. On that same date, the Executive Branch published Decree No. 608/2024 in the Official Gazette, which regulated various provisions of the Tax Package. Chapter II of this Decree specifically outlines the Asset Regularization Regime, designed to incentivize taxpayers to declare unregistered assets. The Asset Regularization Regime was structured in three stages. The first stage ran from October 1, 2024, to November 8, 2024, during which a 5% rate was 3 Table of Contents applied to amounts exceeding US$ 100,000. The second stage took place from November 9, 2024, to January 31, 2025, with the rate increasing to 10%. Finally, the third stage covered the period from February 1, 2025, to April 30, 2025, with the rate rising to 15%. The regime ultimately reached US$ 116.8 billion, surpassing initial expectations under the Milei administration. On August 5, 2024, Decree No. 695/2024 was published in the Official Gazette, regulating, among other matters, four chapters of Title II of the Bases Law: (i) Administrative reorganization; (ii) Privatizations; (iii) Administrative procedure; and (iv) Public employment. A week later, on August 12, 2024, Decree No. 713/2024 was issued, advancing the regulation of Title III of the Bases Law, specifically addressing 'Contracts and Transactional Agreements,' with particular focus on Chapter I, 'Force majeure in existing contracts and transactional agreements,' as well as certain articles of Chapter II, 'Concessions.' Additionally, on August 23, 2024, the Executive Branch published Decree No. 749/2024, which regulated Title VII of the Bases Law in relation to the RIGI. On November 29, 2024, the Executive Branch published Decree 1057/2024 in the Official Gazette, where the amendments introduced by the Bases Law to the Hydrocarbons Law, the Gas Law No. 24,076 and the aspects related to the uniform environmental legislation for the sector were regulated. Regarding Argentina's capacity to obtain financing from international capital markets, on May 13, 2024, the IMF announced that its Executive Board and Argentine authorities had reached an agreement on the eighth review under the agreement with Argentina. As a result, the Board's decision allowed an immediate disbursement of approximately US$ 800 million, bringing the total disbursements under the agreement to approximately US$ 41.4 billion. The Staff-Level Agreement aims at lowering the fiscal deficit, inflation and subsidies, among others, with the goal of promoting the necessary stability conditions to address existing structural challenges and to strengthen the foundations for sustainable and inclusive growth. Subsequently, on March 19, 2025, the Argentine Congress validated the presidential decree authorizing the execution of a new debt refinancing agreement with the IMF, which, according to the technical agreement reached by the IMF and the Argentine authorities on April 8, 2025, would enable a new extended funding facility of US$ 20 billion over a period of 48 months. The IMF Executive Board approved said agreement on April 11, 2025. In January 2025, the IMF Executive Board conducted an ex-post evaluation of Argentina's exceptional access to financing under the 2022 Extended Fund Facility. The evaluation concluded that, while the program did not meet its initial objectives, it allowed for the rescheduling of payments. The program's gradual approach was insufficient to address the economic challenges. However Milei’s administration renegotiated new targets and, in 2024, met all the established parameters, except for the accumulation of net reserves. According to IMF reporting, by the end of 2025 Argentina’s economy had returned to positive growth, and inflation declined substantially from prior peaks, although it remained elevated by historical standards. According to INDEC's last published information, consumer prices increased by 31.5% on a year-on-year basis during 2025. Nonetheless, in its January 2026 report, the IMF projects that Argentina's GDP will stabilize, with a projected annual growth of 4% for 2026 and 2027. A decline in international demand for Argentine products, a lack of stability and competitiveness of the peso against other currencies, a decline in confidence among consumers and foreign and domestic investors, the persistence or reacceleration of inflationary pressures and future political uncertainties, adverse climate conditions affecting agriculture, among other factors, may continue to adversely affect the development of the Argentine economy, which could lead to a reduced demand for our products and services and adversely affect our business, financial condition and results of operations. If current fiscal surplus is not maintained, the Argentine economy could be adversely affected, negatively impacting our business and results of operation. In the past, Argentina has experienced significant macroeconomic imbalances, including frequent and critical fiscal deficits. The Argentine government has recorded an annual fiscal deficit during approximately 90% of the years during the period from 1961 to 2022 (48 years out of 53), which has led to very vulnerable macroeconomic conditions. The Argentine government has financed its fiscal deficit mainly in two ways: (i) by issuing foreign debt, which has historically led to rapid increments in national debt levels; and (ii) by monetary emission through the BCRA, which has led to periods of high inflation and, even in some cases, hyperinflation. The fiscal deficit reached 3% of the GDP in 2021, 2.4% of the GDP in 2022 and 2.9% of the GDP in 2023. However, as a result of the measures taken by Javier Milei's administration, a financial surplus of 0.3% of GDP was recorded in December 2024, marking the first surplus since 2010. During 2025, the 4 Table of Contents Argentine government continued to report monthly fiscal surpluses, resulting in an annual surplus of approximately 0.2% of GDP, reflecting the continuation of fiscal consolidation measures. Failing to maintain the current fiscal surplus and reverting to the historical deficits could lead to growing levels of uncertainty regarding Argentina’s macroeconomic conditions. In particular, it could lead to growing inflation rates and unanticipated foreign exchange depreciation and balance of payments crisis, higher local vulnerability to international credit crisis or geopolitical shocks, higher interest rates and erratic monetary policies, a reduction in real salaries and as a consequence, in private consumption, and a reduction in growth rates. This level of uncertainty, over which we have no control, may adversely affect our financial condition or results of operations. If the current levels of inflation do not decrease, the Argentine economy could be adversely affected, negatively impacting our results of operations and margins. Historically, inflation has materially undermined the Argentine economy and the Argentine government’s ability to create conditions for long-term economic growth. In recent years, Argentina has experienced high inflation rates. Since 2008, the Argentine economy has been subject to strong inflationary pressures that, according to private sector analysts, reached an average annual rate of 28.2% between 2010 and 2015. In December 2015, the administration of former President Macri suspended the publication of indexes and statistics and, after implementing certain methodological reforms and adjusting certain macroeconomic statistics, resumed its publication of the CPI in June 2016. Based on the revised information provided by INDEC, inflation reached an annual rate of 94.8% in 2022, 211.4% in 2023, 117.8% in 2024 and 31.5% in 2025, which represents the lowest rate since 2017 (24.8%). This result marks the second consecutive year of decline in the annual rate of inflation, something that had not occurred since the period between 2007 and 2009. Efforts by successive governments to curb inflation, including price controls and regulation of exports, have faltered, failing to address the structural causes of inflation. Former President Alberto Fernández's administration aimed to shield consumers through price ceilings on essentials and export limits, but recorded fiscal deficits of 2.4% in 2022 and 2.9% in 2023. The current government achieved a primary surplus of 1.8% of GDP and an overall fiscal surplus of approximately 0.3% of GDP in 2024, marking the first surplus in many years. Building on this, 2025 closed with a primary fiscal surplus of roughly 1.4% of GDP and an overall financial surplus of about 0.2% of GDP, representing the first time since the early 2000s that Argentina has reported two consecutive years of positive fiscal balances. However, despite the abovementioned progresses, while inflation declined in 2025 compared to previous years, the persistence of inflationary pressures remains a key risk for 2026. Failure to rectify structural inflationary imbalances could perpetuate rising inflation levels, adversely affecting Argentina's economy. High inflation undermines foreign competitiveness, exacerbates social and economic inequality, and erodes confidence in the banking system, potentially restricting credit access for local companies. Inflation in Argentina has contributed to a material increase in our costs of operation, in particular labor costs; it also enables a reduction in the purchasing power of the population, thus increasing the risk of a lower level of product consumption from our customers in Argentina, which could negatively impact our financial condition and results of operations. Inflation rates could continue to grow in the future, and there is uncertainty regarding the effects that any measures adopted by the government could have to control inflation. Fluctuations in the peso exchange rate, including potential appreciation or depreciation may adversely affect our results of operations, our capital expenditure program, and the ability to service our liabilities and transfers of funds abroad. Argentina has a history of high volatility in its foreign exchange markets, including sharp and unanticipated devaluations, tight foreign exchange controls and severe restrictions on foreign trade. While the devaluation of the peso may have a negative impact on the ability of certain Argentine businesses to pay their foreign currency denominated debt and could lead to higher inflation and reduced real wages, a significant appreciation of the peso could make our products more expensive in both domestic and international markets, potentially reducing demand and jeopardizing our business, which depends on domestic market demand. After several years of moderate variations in the nominal exchange rate, in 2011 the depreciation of the peso commenced to accelerate again and in response the Argentine government further strengthened the foreign exchange restrictions and controls. This provoked the development of an unofficial U.S. dollar trading market at which the U.S. dollar exchange rate was substantially higher than in the official foreign exchange market (the “FX Market”). 5 Table of Contents Given the political and economic landscape, the administration of former President Macri re-introduced rigid restrictions and foreign exchange controls on September 1, 2019, which among other things, significantly curtailed access to the FX Market by individuals and entities. See "Item 10.D. Additional Information—Exchange Controls”. Despite the measures adopted by the Argentine government to try to control the increasing depreciation of the peso, in 2022 the peso depreciated by approximately 70% and in 2023, by approximately 356% against the U.S. dollar, based on the official exchange rates published by the Argentine Central Bank. On December 12, 2023, the Minister of Economy, Luis Caputo, announced the setting of the official exchange rate at Ps. 800 and a 2% monthly “crawling peg.” This resulted in an exchange rate jump of 118.57% for the wholesale dollar and a sharp depreciation of the peso against the dollar. The peso accumulated a depreciation of 26.7% in 2024. By December 2024, the official exchange rate had increased 27.7% compared to its value at the end of the previous year. Additionally, several parallel U.S. dollar trading markets developed in which the Argentine peso-U.S. dollar exchange rate differs from the official Argentine peso-U.S. dollar exchange rate. See "Item 10.D. “Additional Information – Exchange Controls.” On January 13, 2025, the BCRA announced a reduction in the pace of the crawling peg from 2% to 1% per month, effective from February 1, 2025, as part of its managed exchange rate regime, In April 2025, in connection with the new IMF financing arrangement, Argentina’s authorities substantially liberalized foreign exchange policy, replacing the crawling peg with a more flexible system under which the official exchange rate is permitted to trade within an established band (for example, roughly 1,000 to 1,400 pesos per U.S. dollar) and allowing market forces greater influence over the peso's value. Throughout 2025, the official peso-U.S. dollar exchange rate exhibited significant volatility, and the gap between official and parallel exchange rates narrowed markedly as controls were lifted and the trading band framework became operative. Exchange rate developments have implications for the inflation outlook, competitiveness of exports and import pricing, and could affect cost structures and activity levels in sectors such as construction. The official exchange rate movements and the existence of various peso-U.S. dollar exchange rates — including official, market bands, and parallel rates — are described further in “Item 10.D — Additional Information – Exchange Controls.” While the depreciation of the peso can have positive effects on the competitiveness of certain sectors of the Argentine economy, including our business, significant appreciation or continued volatility can negatively impact our competitive position and profitability. Furthermore, both devaluation and appreciation of the peso have had and could continue to have a negative impact on the financial condition of many Argentine businesses and individuals. The devaluation of the peso has negatively affected the ability of certain Argentine businesses to honor their foreign currency-denominated debt and has also led to very high inflation initially and significantly reduced real wages. Conversely, a significant appreciation of the peso could negatively impact businesses whose success is dependent on export markets. Both scenarios can adversely affect the Argentine government’s ability to honor its foreign debt obligations. Significant depreciation or appreciation of the peso, or increased exchange rate volatility, could adversely affect the Argentine economy and, consequently, our business. In recent years, the peso experienced significant devaluations against the U.S. dollar. The U.S. dollar exchange rate increased by approximately 72% in 2022, 356% in 2023, 27.7% in 2024 and 41.3% in 2025. Additional volatility, appreciation, or depreciation of the peso, or reduction in the BCRA’s international reserves due to currency interventions could adversely affect the Argentine economy, which in turn may have an adverse effect on our financial conditions and results of operations. Any further significant fluctuation in the value of the peso, including divergence between official and parallel market rates (which reached 60-70% by the end of 2024), could have material adverse effects on the Argentine economy, which could have a material adverse effect on our results of operations and financial condition. Given the economic and political conditions in Argentina, we cannot predict whether, and to what extent, the value of the peso may depreciate or appreciate against the U.S. dollar, the euro or other foreign currencies. We cannot predict how these conditions will affect our capital expenditure program, the consumption of products we provide to local customers or our ability to meet our liabilities denominated in currencies other than the peso. Furthermore, our ability to transfer funds abroad and our ability to pay dividends to shareholders located abroad may be jeopardized if high exchange rate volatility continues and exchange controls are increased in Argentina. Finally, we cannot predict whether the Argentine government will further modify its monetary, fiscal or exchange rate policy in the future. Negotiations with labor unions could require private companies to implement salary increases or provide workers with additional benefits, all of which could increase our operating costs. 6 Table of Contents Labor relations in Argentina are governed by specific legislation, such as Labor Contract Law No. 20,744 and Collective Bargaining Law No. 14,250, which, among other things, dictate how salary and other labor negotiations are to be conducted. Every industrial or commercial activity in Argentina is regulated by a specific collective bargaining agreement, or CBA, that groups companies together according to industry sector and trade union. Although the process of negotiation is standardized, each chamber of industrial or commercial activity separately negotiates the increases of salaries and labor benefits with the relevant trade union covering such commercial or industrial activity. In the cement industry, salaries have been established generally on an annual basis through negotiations between the chambers that represent the cement producers and the cement industry employees’ trade union. Although due to the high inflation over the past years, these negotiations have taken place more than once a year, they have become less frequent since the start of the Milei administration due to the slowdown in inflation, with the expectation of returning to a scheme of annual increases. The national labor authority (National Secretary of Labor, Employment and Social Security) mediates between the parties and ultimately approves the salary increase to be applied in the cement industry. Parties are bound by the final decision once it is approved by the labor authority and must observe the established salary increases for all employees that are represented by the cement union and to whom the collective bargaining agreement applies. The policy of the current administration is to adopt a stricter approach when assessing and approving wage increase agreements, particularly if such increases exceed the monthly inflation rate. Due to high levels of inflation, Argentine employers, in both the public and private sectors, have in the past experienced significant pressure from their employees and labor organizations to increase wages and to provide additional benefits. Since December 2024, the minimum salary was raised from Ps. 279,718 to Ps. 344,800, as of December 2025 (in nominal terms). Notwithstanding this, over the past year inflation slowed down significantly, with a year-on-year inflation rate of 31.5% in 2025 compared to 117.8% in 2024. The INDEC publishes the "Coeficiente de Variación Salarial" (Salary Variation Index), an index that shows the evolution of salaries. The Salaries Index showed an increase in registered private sector salaries of approximately 147.5% in 2024 and 43.1% in 2025. During this period, the average wages in the cement industry increased in line with the average of private sector salaries, according to the Argentine Secretary of Labor, Employment and Social Security. Recently, the Argentine Congress passed Law No. N°27,802, which entered into force on March 6, 2026, and significantly amends collective labor law in Argentina. Within one year of the law’s promulgation, the parties to each CBA will be summoned to negotiate, renegotiate, and/or ratify their agreements. Furthermore, the amendments to the collective labor regime aim to grant companies greater participation in collective bargaining. In this regard, the new legislation places a strong emphasis on company labor unions and the possibility of negotiating company‑specific collective bargaining agreements. The effectiveness of certain provisions of the recently enacted Argentine labor reform may be subject to judicial review, creating uncertainty regarding the applicable labor framework. Any salary increase or additional benefit resulting from negotiations with the labor union could result in an increase in costs and a decrease in the results of the operations of Argentine companies, including those of Loma Negra. The implementation of exchange controls and restrictions on capital inflows and outflows could limit the availability of international credit and could threaten the financial system, adversely affecting the Argentine economy and, as a result, our business. Due to the foreign exchange crisis generated in August 2019 and the continued reduction of the BCRA’s foreign currency reserves, since September 1, 2019, the Argentine government imposed rigid exchange controls and transfer restrictions, substantially limiting the ability to obtain foreign currency or make certain payments or distributions out of Argentina See “Item 10.D. Additional Information—Exchange Controls”. In response to the re-imposed foreign exchange restrictions, an unofficial U.S. dollar trading market developed again in which the peso-U.S. dollar exchange rate differed substantially from the official peso-U.S. dollar exchange rate in the FX Market. In addition, access to foreign currency and its transfer out of Argentina can also be obtained through capital markets transactions denominated Blue-Chip Swaps, subject to certain restrictions and side effects which is more expensive than acquiring foreign currency in the FX Market. Notwithstanding the measures adopted by the Argentine government in the past years, President Javier Milei's administration has been gradually easing foreign exchange controls, most notably through the implementation of a more flexible exchange rate band regime and the easing certain restrictions on access to the official foreign exchange market. 7 Table of Contents However, future actions by the Argentine government could include reinstating further exchange controls, transfer restrictions, restrictions on the free movement of capital, and may implement other measures in response to capital flight or a significant depreciation of the peso, which could further limit our ability to access the international capital markets and impair our ability to make interest, principal or dividend payments abroad. Such measures could lead to renewed political and social tensions, and could undermine the Argentine government’s public finances, which could adversely affect Argentina’s economy and prospects for economic growth and, consequently, adversely affect our business and results of operations, and could further impair our ability to make dividend payments to holders of the ADSs, which may adversely affect the market value of the ADSs. Any inability to maintain a favorable current account or balance of payments position may result in a depreciation of the peso, affecting our results of operations, our capital expenditure program and our ability to pay our foreign currency liabilities . Inflation continues to be a challenge for Argentina given its persistent nature in past years. According to INDEC, Argentina’s structural current account accumulated a surplus of US$ 3,287 million in 2021 and a current account deficit of US$ 3,031 million in 2022. In 2023, the Argentine economy recorded a current account deficit of US$ 6,900 million. In 2024, the Argentine current account shifted to a surplus, supported by a strong trade balance and reduced services and income outflows, with an approximate surplus of US$ 1,029 million for 2024 as a result of cost reduction policies. In 2025, external account dynamics deteriorated again through the first and second quarters, with quarterly data showing current account deficits, reflecting a return to current account deficits after the temporary surplus in 2024, driven by growing deficits in services and primary income and volatility in trade flows. However, Argentina closed 2025 with a primary fiscal surplus of 1.4% of GDP, which, after paying interest on public debt, became a financial surplus of 0.2%, according to the Ministry of Economy. Argentina recorded a primary fiscal surplus of Ps. 11.8 trillion (about US$ 8.1 billion) in 2025 and a financial surplus (including debt service payments) of Ps. 1.45 trillion (about US$1 billion), marking the second consecutive annual financial surplus, following the first in more than a decade in 2024. Because foreign direct investment remains stagnant in Argentina, Argentina and its provinces may not be able to fulfill their debts obligations in the future, since Argentina’s foreign currency needs would severely overcome its foreign currency sources. If this level of uncertainty prevails on international investors, Argentina may suffer a “sudden stop” event, when investors stop lending money to Argentinean institutions. This, in turn, may result in large capital outflows that could lead the Argentine government to default on its debt and cause a rapid and unanticipated depreciation of the peso, an increase in local interest rates and a banking system crisis if bank deposits are largely withdrawn following social unrest. The measures taken during former president Fernandez administration could not stop the constant devaluation of the peso against the U.S. dollar. Between January 2020 and December 2023, the official nominal exchange rate for pesos into U.S. dollars fell by approximately 1250.80%. As of December 31, 2024, the official nominal exchange rate for pesos into U.S. dollars fell to Ps. 1,032.5 per US$1.00, a devaluation of approximately 27.7%. During 2025, Argentina transitioned to an exchange rate band regime launched by the BCRA on April 11, 2025, under which the peso has initially been allowed to fluctuate within a band between approximately ARS 1,000 and ARS 1,400 per US$ 1.00, with periodic adjustments intended to promote orderly market functioning and support monetary policy objectives. Throughout 2025, the official exchange rate remained within and around this band, with the BCRA periodically adjusting the upper and lower limits to reflect market and policy conditions. By late December 2025, the official intervention band ranged between approximately Ps. 916 to Ps. 1,526 per US$ 1.00, reflecting the cumulative adjustments over the year. These developments represent a material shift toward a more flexible exchange rate framework for the peso. While Argentina recorded a structural current account surplus in 2024 and 2025 and fiscal surpluses during 2024‑2025, there remains uncertainty regarding the sustainability of these trends in the context of potential macroeconomic shocks. The failure to sustain fiscal surpluses and the return to fiscal deficits could increase the level of uncertainty regarding the macroeconomic conditions in Argentina. In particular, it could lead to an increase in the inflation index, devaluation of the peso with respect to foreign currencies and a subsequent crisis in the balance of payments, greater local vulnerability to the international credit crisis or geopolitical shocks, rising rates of interest, erratic monetary policies, reduction in real wages and, as a consequence, in private consumption and reduction in growth rates. This level of uncertainty, over which we have no control, can affect our financial condition or the results of operations. 8 Table of Contents If a balance of payments crisis were to occur, a large depreciation of the peso against the U.S. dollar could adversely affect our ability to meet our foreign currency obligations. Furthermore, the negative effect such a crisis could have on the growth rates of the Argentine economy and its consumption patterns could have a material adverse effect on our business, financial condition and result of operations. The Argentine government’s ability to obtain financing from international markets may be limited, which may negatively impact our financial condition and our ability to grow. Argentina’s sovereign default in 2001 limited its ability to access international financing. Through exchange offers conducted between 2005 and 2010, Argentina restructured over 92% of the sovereign defaulted debt. However, holdout holders declined to participate in the restructuring commenced litigation against Argentina. The Argentine government settled US$9.2 billion outstanding principal amount of the untendered debt held by some of these holdout holders in April 2016 with the proceeds from a US$16.5 billion international bonds offering. Although the size of the outstanding claims has decreased significantly, as of the date of this annual report, litigation initiated by bondholders that have not accepted Argentina’s settlement offer continues in several jurisdictions. However, after the settlement with the holdouts and offering Argentina regained access to the international capital markets. Additionally, foreign shareholders of several Argentine companies have filed claims before the International Center for Settlement of Investment Disputes or the ICSID alleging that the emergency measures adopted by the Argentine government since the crisis in 2001 and 2002 differ from the just and equal treatment standards set forth in several bilateral investment treaties to which Argentina is a party. The ICSID has ruled against Argentina with respect to many of these claims. Moreover, Argentina's ability to obtain financing from international capital markets has historically been subject to various limitations and challenges, as evidenced in past years, where the need to resort to international organizations has been recurring. In 2018, the IMF´s executive board approved the Stand-By Agreement with the Argentina government, which involved the disbursement of US$ 44 billion. On January 28, 2022, the IMF and the Argentine Government reached an understanding to restructure the current debt with the IMF though an Extended Fund Facility Arrangement which was approved by the IMF’s executive board on March 3, 2022, and approved by the Argentine Congress on March 17, 2022. Ultimately, the Extended Fund Facility Arrangement was approved definitely by the IMF´s executive board on March 25, 2022. The Extended Fund Facility Arrangement sought to continue creating the necessary stability conditions to address existing structural challenges and to strengthen the foundations for sustainable and inclusive growth. On August 4, 2023, through the Decree 404/2023 a loan agreement between Argentina and Qatar for 580,000,000 Special Drawing Rights was approved in an attempt to pay interest on the debt contracted with the IMF. In this regard, the Argentine government announced the cancellation of US$ 1,411 million within the framework of the agreement. Moreover, on August 23, 2023, former Economy Minister, Sergio Massa, announced agreements with the World Bank and the Inter-American Development Bank that determined that these entities would provide Argentina with total financing of US$ 1,310 million. Furthermore, through the press release of February 1, 2024, IMF’s Executive Board announced the conclusion of the seventh review of the agreement with Argentina. This decision grants the country access to an immediate disbursement of approximately USS 4.7 billion, which placed the total disbursements under the agreement at around USS 40.6 billion so far. On the other hand, in the press release dated May 13, 2024, the IMF announced that the IMF Executive Board and Argentine authorities reached an agreement on the eighth review under the agreement with Argentina. As a result, the Board's decision allowed an immediate disbursement of approximately US$ 800 million (or SDR 600 million), bringing the total disbursements under the agreement to approximately US$ 41.4 billion. In January 2025, the IMF Executive Board evaluated Argentina's exceptional access to financing under the 2022 Extended Fund Facility. Although the program did not meet its initial objectives, it allowed for the rescheduling of payments. The program's gradual approach was insufficient to address the economic challenges; however, the measures implemented by the Milei administration contributed to stabilization. In this context, the Milei administration renegotiated new targets and, in 2024, met all the established parameters, except for the accumulation of net reserves. On March 19, 2025, the Argentine Congress validated the presidential decree authorizing the execution of a new debt refinancing agreement with the IMF. On April 8, 2025, the IMF reached a technical agreement with the Argentine 9 Table of Contents government for a new US$ 20 billion extended facility over 48 months, subject to quarterly target reviews and a repayment term of 10 years. This agreement was approved by the IMF Executive Board on April 11, 2025, authorizing disbursements for up to US$ 15 billion in 2025, which were available for use without specific restrictions, providing Argentina flexibility in addressing its financial needs. This arrangement was intended to support Argentina's stabilization agenda, strengthen external sustainability and facilitate progress toward a more durable re-access to international capital markets. Following the renegotiated agreement, the first disbursement of US$ 12 billion was made on 15 April 2025, bringing Argentina’s international reserves to US$36,799 million. Subsequently, after the initial disbursement, the IMF completed the first review of the 48-month Extended Fund Facility in July 2025, enabling an additional disbursement of approximately US$ 2 billion under the program. The Argentine government has also secured additional support from multilateral institutions. For example, in April 2025, the World Bank approved approximately US$ 1.5 billion in financing to support Argentina's reform agenda, as part of a broader potential financing package that includes additional commitments from the World Bank Group and the Inter-American Development Bank intended to support policy measures, productivity and investment. Moreover, the BCRA executed and expanded its international Repurchase Agreement (Repo) with global banks during 2025. Following the initial Repo facility executed in January 2025, the BCRA conducted a subsequent Repo transaction in June 2025 for approximately US$ 2 billion with seven international banks as part of its efforts to strengthen gross international reserves. Subsequently, in January 2026, the BCRA closed a further Repo arrangement for US$ 3 billion with six international financing institutions, demonstrating continued access to market-based financing and reinforcing the central bank's liquidity and reserve position. The BCRA also agreed with the People’s Bank of China (PBOC) to extend the active tranche of the bilateral currency swap line for CNY 35,000 million (equivalent to US$ 5 billion) for an additional 12-month term through mid-2026, helping support the management of external liquidity. The activation of this tranche, which started in 2023 and was gradually reduced from June 2025, will remain fully available to the BCRA until mid-2026, allowing the BCRA to reduce risks in its transition towards a sound and sustainable monetary and exchange rate regime in a challenging international context for foreign capital flows. In any case, lack of access to international or domestic financial markets or increase in the costs of such financing could affect the projected capital expenditures for our operations in Argentina, which, in turn, may have an adverse effect on our financial condition or the results of our operations. For more information regarding Argentina’s financings, including the aggregate of US$ 23.5 billion loans disbursed in connection with the Staff-Level Agreement, see “—Investing in a developing economy such as Argentina entails certain inherent risks.” Government intervention may adversely affect the Argentine economy, Argentine companies and, as a result, our business and results of operations. During recent years, the federal government has exercised substantial control over the Argentine economy. In December 2019, Alberto Fernández assumed the presidency of Argentina and implemented several measures that increased state intervention, such as: i) the Social Solidarity Law; ii) the Price Control Program; iii) the Public Debt Sustainability Law under Foreign Law; iv) the Shelving Law; and v) Decree No. 690/2020, which regulated the tariffs of certain services. In this same regard, on September 1, 2019, strict exchange controls and restrictions were reinstated, limiting access to the Foreign Exchange Market for purchases and transfers of foreign currency outside Argentina. The Argentine Executive Branch issued the Decree No. 332/2022 which established a progressive reduction of state´s aid in relation to the payment of electric and natural gas services. This reduction depends on the income of the consumer. Under this system, higher income consumers will be paying their tariffs with no state aid in the future, whereas vulnerable and low-income consumers will still receive state aid. The National Telecommunications Agency issued Resolution No. 1754/2022, which established a maximum fee increase for mobile services, as well as use of internet value added services, subscription radio broadcasting services and subscription broadcasting services through satellite by certain licensees. Interventions by the Argentine government similar to those described above can have an adverse impact on the level of foreign investment in Argentina, the access of Argentine companies to the international capital markets and 10 Table of Contents Argentina’s commercial and diplomatic relations with other countries and, consequently, could adversely affect our business, financial condition and results of operations. As of the date of this annual report, the potential for the current administration to introduce further price control measures on our products remains uncertain. Should such measures be enacted, their impact on our operations and financial results cannot be predicted. Government actions like expropriations and interventions, as previously described, could harm foreign investment levels, limit access to international capital markets for Argentine companies, and strain Argentina's commercial and diplomatic relationships. These outcomes could negatively affect our business, financial health, and operational results. Conversely, the Milei Administration is steering towards reducing government intervention through deregulation efforts aimed at alleviating the economic and social crisis. However, it is not possible to predict the level of success of such efforts and measures and their impact in our operations and financial performance. The Argentine economy could be adversely affected by economic developments in other markets and by more general “contagion” effects. Weak, flat or negative economic growth in any of Argentina’s major trading partners, such as Brazil, could adversely affect Argentina’s balance of payments and, consequently, economic growth. The Argentine economy may also be affected by conditions in developed economies, such as the United States, that are significant trading partners of Argentina or have influence over world economic cycles and over short-term evolution of commodity prices. If interest rates increase significantly in developed economies, including the United States, Argentina and its developing economy trading partners, such as Brazil, could find it more difficult and expensive to borrow capital and refinance existing debt, which could adversely affect economic growth in those countries. Decreased growth from Argentina’s trading partners could also have a material adverse effect on the markets for Argentina’s exports and, in turn, adversely affect economic growth. Any of these potential risks to the Argentine economy could have a material adverse effect on our business, financial condition and result of operations. The economy of Brazil, Argentina’s largest export market and the principal source of imports, experimented heightened negative pressure due to the uncertainties stemming from ongoing political crisis. After the economic crisis of 2015 and 2016, the Brazilian economy is slowly recovering. The real growth per capita has recovered 10% in 2021, but is still 15% down from 2019 figures. As of December 31, 2022, the unemployment rate was 8.3%, as compared to 11.9% at the end of 2021. As of December 31, 2024, the unemployment rate is 6.2% as compared to 7.4% at the end of 2023. On January 1, 2022, Lula da Silva assumed office as a left-wing politician. While the impact of Brazil’s downturn on Argentina cannot be predicted, we cannot exclude the possibility that the Brazilian political and economic crisis could have a further negative impact on the Argentine economy. During 2025, the economy of Brazil showed some progress but with slowing momentum and important policy challenges. According to official and institutional projections, Brazil’s central bank maintained relatively high benchmark interest rates (around 15%) throughout the year, with inflation gradually moderating toward single-digit levels, while the labor market remained tight by historic standards and unemployment stayed near multi-year lows. However, recent indicators pointed to a loss of momentum in activity in the second half of 2025, including weak industrial output and subdued services growth, suggesting a more moderate pace of expansion for the full year compared with earlier quarters. Notwithstanding the foregoing, a new devaluation of the Brazilian real similar to the one that occurred in 2024 (which, from the beginning of 2024 until January 2025, reached nearly 20%) could result in a decline in Argentine exports and a loss of competitiveness, along with an increase in imports, as Brazilian goods would become more price-competitive in international markets. This could potentially adversely affect the growth of the Argentine economy and its financial position. International political events and commodity price volatility could adversely affect Argentina’s economy Changes in social, political, regulatory, and economic conditions in the United States, particularly concerning trade policies, could create uncertainty in international markets and negatively impact emerging market economies, including the Argentine economy. This could, in turn, have a negative impact on our business, results of operations, and financial condition. 11 Table of Contents On November 5, 2024, Donald Trump was elected President of the United States. Since taking office on January 20, 2025, his administration has enacted significant trade tariffs affecting global markets. Notably, a 104% levy on Chinese imports following increased retaliatory actions by China. These tariffs were escalated from previous rates due to diplomatic tensions and are expected to rise the average tariff on Chinese exports to the U.S. to nearly 125%. Meanwhile, other countries, including the European Union, face new tariff rates ranging from 11% to 50%. These measures contribute to market instability and may disrupt trade flows to Argentina, impacting import costs and the broader economy. These actions, along with potential further retaliatory measures from China—such as tariffs on U.S. agricultural products and restrictions on market access—threaten global trade stability and could disrupt economic conditions, impacting Argentina through altered trade flows and increased costs for imported goods crucial to various sectors, including ours. Meanwhile, the long-standing geopolitical tensions have not abated. On February 24, 2022, Russian military forces launched a major assault against Ukraine, which led to a conflict that is ongoing as of the date of this annual report. Trade disruptions caused during 2022 and 2023 by the conflict and economic sanctions caused instability and increases in the prices of energy which affected the costs of our products. Despite the fact that during 2024 the energy market normalized, we cannot estimate the future impact on our operations that the continuation of this conflict may cause. Throughout 2025 and into 2026, the protracted nature of this conflict, combined with shifting sanctions regimes, has maintained volatility in global energy and fertilizer markets, directly impacting our operational costs and the logistics of our supply chain. The October 7, 2023, assault by Hamas on Israel further exacerbated geopolitical instabilities, culminating in Prime Minister Netanyahu's declaration of war and a full blockade on Gaza. Even though a ceasefire was reached on January 19, 2025, between Israel and Hamas, allowing a temporary reduction of the intensity of hostilities and the entry of humanitarian aid, the region remained politically fragile throughout 2025, with sporadic incidents and heightened regional tensions. The withdrawal from the Netzarim Corridor and U.S. President Trump’s plan for Gaza underline ongoing tensions. In late February and March 2026, a major international conflict erupted after the United States and Israel launched large-scale airstrikes against Iran, targeting military, government, and nuclear-related infrastructure and killing Iran’s Supreme Leader, Ayatollah Ali Khamenei. Iran responded with widespread missile and drone attacks against Israel, U.S. bases, and several Gulf countries, drawing in regional actors and disrupting airspace, energy infrastructure, and civilian life across the Middle East, while the fighting caused significant casualties, displacement, market volatility, and intense international diplomatic efforts aimed at preventing further escalation into a broader war. These developments have increased uncertainty in international markets, disrupted energy markets and maritime trade routes, and could contribute to volatility in global financial conditions, potentially affecting emerging economies such as Argentina. As of April 2026, while diplomatic efforts are ongoing, the conflict continues to cause severe disruptions to global energy markets and key maritime trade routes, including the Red Sea and the Strait of Hormuz. These events have led to sustained volatility in commodity prices and a "risk-off" sentiment in global financial markets. For emerging economies like Argentina, these developments may result in increased financing costs, fluctuations in energy import prices, and general instability in international trade, all of which could adversely affect our financial condition and results of operations. Argentina is highly dependent on the export of certain commodities, such as soy, which has made the Argentine economy more vulnerable to fluctuations in the commodities prices. If international commodity prices decline, the Argentine economy could be adversely affected. In addition, adverse weather conditions can affect the production of commodities by the agricultural sector, which account for a significant portion of Argentina’s export revenues. During 2025, although the agricultural sector recovered from previous droughts, commodity price fluctuations—driven by the aforementioned geopolitical tensions and changes in Chinese demand—remained a critical vulnerability for Argentina’s foreign exchange reserves. All these circumstances could have a negative impact on the levels of government revenues, available foreign exchange and the government’s ability to manage its sovereign debt, and could either generate recessionary or inflationary pressures, depending on the government’s reaction. Either of these results would adversely impact Argentina’s economic growth and, therefore, our financial condition and results of operations. 12 Table of Contents The Argentine banking system may be subject to instability, which may affect our operations. The Argentine banking system has experienced several crises in the past, and even collapsed in 2001 and 2002. In recent years, the Argentine financial system grew significantly with a marked increase in loans and private deposits, showing a recovery of the credit activity. Such recovery has been severely impacted by the COVID-19 pandemic. Although the financial system’s deposits continue to grow in nominal terms, these deposits are mostly short-term and the sources of medium and long-term funding for financial institutions are currently limited, despite some improvement in market conditions during 2025. During 2024, the financial system accrued earnings and maintained high soundness indicators, reinforcing its resilience against potential risks. The provision of payment services continued to grow along the year. Moreover, throughout the year, the stock of financing in pesos to the private sector regained momentum and accumulated an increase of 49.4% year-on-year in real terms, across all groups of financial institutions. The stock of credit in foreign currency to the private sector increased 16.8% in the last month of the year (in original currency), tripling in year-on-year terms. Additionally, the broad liquidity of the financial system in pesos represented 35.9% of pesos deposits at the end of the year, while the corresponding ratio for the U.S. Dollars segment stood at 72%. Both in monthly and year-on-year comparisons, these ratios decreased as a result of the sustained increase in credit to the private sector. When considering all sectors and currencies, the real balance of total deposits slightly decreased in December (0.4% real), remaining unchanged in a year-over-year comparison. In 2024, fixed-term deposits in pesos from the private sector, as well as means of payment, have shown a decelerated decline due to the drop in inflation as well as in the interest rates. Fixed-term placements have experienced a monthly increase of 3.3% at constant prices as of December 2024. Subsequently, during 2025, the banking system operated within a context of macroeconomic transition, including disinflation, high real interest rates for part of the year and gradual adjustments to monetary and exchange rate policies. While banks generally maintained adequate levels of capitalization and liquidity under regulatory requirements, lending activity remained influenced by macroeconomic conditions, regulatory changes and the pace of normalization of financial markets. Credit to the private sector showed gradual recovery in real terms compared to prior years, although from historically low levels, and foreign currency lending continued to be concentrated in borrowers with export revenues or natural hedges. Deposit levels remained relatively stable in real terms during 2025, supported by the deceleration of inflation and greater monetary stability compared to previous years. However, the maturity structure of deposits continues to be predominantly short-term, which may limit the capacity of financial institutions to expand long-term lending. Financial institutions are subject to significant regulation from multiple regulatory authorities, all of whom may, among other things, establish limits on commissions and impose sanctions on financial institutions. During 2025, the regulatory framework evolved as part of the broader macroeconomic stabilization process, including adjustments to monetary instruments and gradual easing of certain foreign exchange restrictions. Nevertheless, regulatory changes—particularly in a context of structural economic reform—may continue to generate uncertainty for financial institutions and market participants. A new crisis or the consequent instability of one or more of the larger banks, public or private, could have a material adverse effect on the prospects for economic growth and political stability in Argentina, resulting in a loss of consumer confidence, lower disposable income and fewer financing alternatives for consumers. These conditions would have a material adverse effect on us by resulting in lower sales of products and the possibility of a higher level of uncollectible accounts or increase the credit risk of the counterparties regarding our investments in local financial institutions. Exchange controls and restrictions on transfers abroad and capital inflows have limited, and could continue limiting, the availability of international credit. The continued limitation of international credit could have a material adverse impact on our financial condition, results of operations and cash flows. Foreign Exchange Controls Affecting Imports of Goods and Services could adversely affect our business. Argentine companies currently have access to the foreign exchange market to acquire foreign currency to make payments abroad, provided that certain requirements are met. As from April 14, 2025, access to the official foreign exchange market for the payment of new imports of goods has generally been permitted as from the date of customs clearance, subject to compliance with applicable regulations and reporting requirements. However, although certain restrictions affecting access to the foreign exchange 13 Table of Contents market were eased during 2025 as part of the government’s economic reform program, Argentina continues to operate under a regulated foreign exchange regime. We cannot assure you that additional limitations on access to foreign currency for the payment of imports of goods and services to Argentina will not be reestablished or tightened in the future. In this sense, we are unable to estimate the economic and financial impact for our business, or the possibility of other economic effects on the stock market, foreign exchange rates and otherwise. Any such negative impact could result in a material adverse effect on our business, liquidity, financial conditions and results of operations, as well as our ability to achieve our previously disclosed expectations for future years. Disruption or volatility in global financial and credit markets could have a material adverse effect on us. The global financial and credit markets have experienced, extreme volatility and disruptions, including severely diminished liquidity and credit availability, rising interest and inflation rates, declines in consumer confidence, decreases in economic growth, increases in unemployment rates, and uncertainty about economic stability. Such volatility and uncertainty have increased the cost of funding for Argentine and international issuers and borrowers. Recent events have created bank-specific and broader financial institution liquidity risks and concerns. Uncertainty remains regarding liquidity concerns in the financial services industry and potential impacts on the broader global economy. Our business, partners, and the industry as a whole may be adversely impacted in ways that are currently unpredictable. If banks and financial institutions face insolvency or significant financial challenges in the future, based on systemic conditions affecting the banking system and financial markets, our access to existing cash, cash equivalents, and investments may be threatened, possibly causing a material adverse effect on our business and financial condition. Moreover, if any of our customers, suppliers or other parties with whom we conduct business are unable to access funds, their ability to meet obligations to us or engage in new commercial arrangements requiring further payments or funding could be adversely affected. Investor concerns regarding the U.S. or international financial systems could result in less favorable commercial financing terms, including higher interest rates or costs and tighter financial and operating covenants, or systemic limitations on access to credit and liquidity sources, making it more difficult for us to acquire financing on acceptable terms or at all. Any material decline in available funding could have a material adverse effect on us. Risks Relating to Our Former Indirect Controlling Shareholder Adverse events involving our former indirect controlling shareholder and its affiliates, including developments relating to the "Operation Car Wash" ("Operação Lava Jato") investigation in Brazil, may adversely affect our reputation and the trading price of our ordinary shares and ADSs. Mover Participações S.A. ("Mover", formerly Camargo Corrêa S.A.) was our indirect controlling shareholder. Construções e Comércio Camargo Corrêa S.A. ("CCC"), a construction and engineering subsidiary of Mover, and certain of its former senior management and employees have been the subjects of the Brazilian Federal Police investigation referred to as "Operation Car Wash" ("Operação Lava Jato"), which is an investigation into widespread allegations of corruption. Although we are not a party to Operação Lava Jato, and although Mover and its affiliates are no longer either directly or through affiliates part of our ownership chain, we cannot assure you that investors, customers, suppliers, business partners, regulators or other stakeholders will distinguish between us and our former affiliates, or that additional adverse developments involving Mover, CCC, or other former affiliates, including us, will not result in reputational harm to us by association. Any renewed focus, adverse developments, findings, settlements, penalties, civil claims, criminal proceedings, compliance failures, sanctions, or other negative publicity involving Mover, CCC or other former affiliates could adversely affect the perception of our Company and could have a material adverse effect on the trading price and liquidity of our ordinary shares and ADSs. See ‘Item 7.A. Major Shareholders — Significant Changes in Percentage Ownership’. The development of the judicial reorganization process of our indirect controlling shareholder, including a potential marketing process of our Company, may have an adverse effect on our business, financial condition or results of operations and/or the market price of our ordinary shares or ADSs. 14 Table of Contents InterCement Participações S.A., our indirect controlling shareholder, underwent a judicial reorganization process in Brazil, filed on December 3, 2024, following the inability to reach a comprehensive agreement with creditors through its previous out-of-court restructuring efforts. The judicial reorganization process was intended to legally protect and facilitate the restructuring of our indirect controlling shareholder's financial obligations. The judicial reorganization plan presented by InterCement Participações S.A. was approved by creditors on October 6, 2025, and confirmed by the bankruptcy court on December 12, 2025. The judicial reorganization plan provided for, among other things, the capitalization of impaired financial claims on InterCement Participações S.A. As publicly disclosed, on April 6, 2026, we were informed that in accordance with the judicial reorganization plan, an extraordinary shareholders’ meeting of InterCement Participações S.A. approved, among other matters, a capital increase in the amount of R$ 2,816,275,313.89 and the consequent issuance of 1,286,045,664 new shares, which were subscribed by certain creditors of InterCement Participações S.A. who elected to receive shares as a form of payment, and the redemption of all shares owned by Mover. Accordingly, while InterCement Trading e Inversiones Argentina, S.L. remains our direct controlling shareholder and continues to hold the same stake, the indirect ownership of our indirect controlling shareholder has changed. One shareholder of InterCement Participações S.A. holds approximately 38.7%, a second one holds approximately 26.7%, and a third one holds approximately 24.0%, and they have stated that there is no shareholders’ agreement or other agreement among them regarding the corporate governance of such entity or any of its subsidiaries, whether direct or indirect, including the Company. See “ — The share ownership position of our principal shareholders may limit your ability to influence corporate matters, and changes in the indirect ownership of our controlling shareholder may create additional uncertainty regarding how control is exercised over us”, and ‘Item 7.A. Major Shareholders — Significant Changes in Percentage Ownership’. In addition, under the terms of the judicial reorganization plan, Loma Negra may be subject to a marketing process (the "Loma Negra Sale Procedure") for the private sale of all or part of the equity interest indirectly held in us by InterCement Participações S.A., which may involve multiple transactions with multiple counterparties. Following judicial confirmation of the plan, the debtors under the judicial reorganization may initiate the Loma Negra Sale Procedure. Until September 30, 2028, the board of directors of InterCement Participações S.A. would be responsible for conducting the Loma Negra Sale Procedure in accordance with prevailing market best practices. The judicial reorganization plan also grants Marcos Marcelo Mindlin by himself or through any of his affiliates a right of first offer in connection with the Loma Negra Sale Procedure if it is carried out. Net proceeds from the sale of Loma Negra are subject to a payment waterfall pursuant to the plan. If, prior to September 30, 2028, no Loma Negra Sale Procedure occurs, the creditors may be consulted regarding alternative mechanisms for the sale and/or conversion of their debt into shares of Loma Negra. The implementation of the Loma Negra Sale Procedure, and the uncertainty surrounding its ultimate outcome, timing and structure, could increase uncertainty regarding our ownership structure, potentially result in a change of control and create significant volatility in the trading price of our ordinary shares and ADSs. Any sale of our shares by InterCement Participações S.A. or its successors could also result in new controlling shareholders whose strategic priorities may differ from those of the current or prior ownership, which could have a material adverse effect on our business, financial condition or results of operations. Risks Relating to Our Business and Industry The cyclical nature of the cement industry may lead to decreases in our revenues and profit margin. The cement industry is inherently cyclical and sensitive to changes in supply and demand that are, in turn, affected by political and economic conditions in Argentina and elsewhere. This cyclicality may decrease our profit margin. In particular: •downturns in general business and economic activity may cause demand for our products to decline, adversely impacting our sales volume; •when demand falls, we may be under competitive pressure to lower our prices to maintain market share, which could diminish our profit margins; and •if we decide to expand our plants or construct new plants, we may do so based on an estimate of future demand that may never materialize or may materialize at levels lower than we predicted. Should actual demand fall short of our estimates, we may encounter excess capacity and underutilization of our assets. 15 Table of Contents Moreover, the prices we are able to obtain for cement depend in large part on prevailing market prices. Cement is subject to price fluctuations resulting from production capacity, inventories, the availability of substitutes and other factors relating to the market such as the level of activity in residential construction markets, and, in some cases, government intervention. If the price of cement were to decline significantly from current levels, it could have a material adverse effect on us and our profit margin. We are subject to the possible entry of domestic or international competitors into our market, which could decrease our market share and profitability. The cement market in Argentina is competitive and is currently served by four principal groups of companies which together supply substantially all of the cement consumed in the country. In the cement industry, the location of a production plant tends to limit the market that a plant can serve because transportation costs are high, reducing profit margins. Historically, we have been a relevant player with presence across all regions in the country. However, competition could intensify if other players decide to try to enter our market. We may face increased competition from the other cement manufacturers. Even though the industry has installed capacity surplus, current competitors may decide to increase their installed capacity. We also face the possibility of competition in Argentina from the entry into our market of imported clinker, cement or other materials (such as slag) or products from foreign manufacturers, which may have significantly greater financial resources than us. The enactment of regulations on the import of cement may increase the existence of potential foreign competitors in our market. We may not be able to maintain our market share if we cannot match our competitor’s prices or keep pace with the development of new products. If any of these events were to occur, our business, financial condition and results of operations could be adversely affected. A reduction in private or public construction projects in Argentina could have an adverse effect on our business, financial condition and results of operations. Cement consumption is highly correlated to construction levels. Demand for our cement products depends, in large part, on residential and commercial construction and infrastructure developments. Residential and commercial construction, in turn, is cyclical and highly correlated to prevailing macroeconomic factors, including general economic conditions, changes in interest rates, demographic and population shifts, levels of infrastructure spending, and other factors beyond our control. As a result, decline in economic conditions would reduce household disposable income, reduce residential construction and potentially delay infrastructure projects, which would lead to a decrease in demand for cement. As a result, a deterioration in the economic conditions would have a material adverse effect on our financial performance. We cannot assure you that Argentina’s GDP will grow or that the share of Argentina’s GDP dedicated to construction and the infrastructure sectors, will maintain current levels or increase. Significant interruptions or delays in, or the termination of, private or public construction projects may adversely affect our business, financial condition and results of operations. Private and public construction levels in our market depend on investments in the region which, in turn, are affected by economic conditions. Among the measures aimed at eliminating Argentina’s deficit, the Milei administration determined to stop financing public works. According to the monthly report of the Portland Cement Manufacturers Association, in the first quarter of 2025, dispatches increased by 11.0% compared to the same period of the previous year. In the second quarter of 2025, they increased by 14.1%, in the third quarter of 2025, they decreased by 0.9%, and in the fourth quarter of 2025 they increased by 0.6%. During the first quarter of 2026 cement dispatches decreased approximately by 0.4% compared to the same period of 2025. According to INDEC, the surface authorized by building permits decreased by 6.2% in December 2025 compared to the same month in 2024, and formal employment on the sector decreased by 0.3%. If the downturn in the sector continues, the company could be adversely affected in its business, finances and daily operations. Changes in the cost or availability of raw materials supplied by third parties may adversely affect our business, financial condition and results of operations. We use certain raw materials in the production of cement, such as gypsum, slag, iron ore, steel slabs, clay, sand and pozzolana that we obtain from third parties. Our cost of raw materials supplied by third parties as a percentage of 16 Table of Contents our total cost of sales was 12%, 19% and 18% in 2025, 2024 and 2023, respectively. Should existing suppliers cease operations or reduce or eliminate production of these by-products, sourcing costs for these materials could increase significantly or require us to find alternative sources for these materials, which could have a material adverse effect on our business, financial condition, results of operations and prospects. Energy accounts for a significant portion of our total cost of sales, and higher energy prices or governmental regulations that restrict energy available for our operation could materially adversely affect our operations and financial condition. We consume substantial amounts of energy in our cement production processes and currently rely on third-party suppliers for a significant portion of our total energy needs. During the year ended December 31, 2025, thermal energy cost and electricity cost represented approximately 11% and 8% of our total cost of sales, respectively, and in 2024 and 2023, thermal energy cost and electricity cost represented approximately 13% and 8% and 16% and 8% of our total cost of sales, respectively. Our results of operations may be adversely affected by higher costs of electricity or unavailability or shortages of electricity, or an interruption in energy supplies. For more information, see "Item 5.A. Operating and Financial Review and Prospects—Operating Results." Electricity shortages have occurred in Argentina in the past and could occur again in the future, and there can be no assurance that power generation capacity will grow sufficiently to meet our demand. In recent years, the condition of the Argentine electricity market has provided little incentive to generators to further invest in increasing their generation capacity, which would require material long-term financial commitments. As a result, Argentine electricity generators are currently operating at near full capacity and could be required to ration supply in order to meet a national energy demand that exceeds the current generation capacity. In addition, the 2001 economic crisis and the resulting emergency measures had a material adverse effect on other energy sectors, including oil and gas companies, which led to a significant reduction in natural gas supplies to generation companies that use this commodity in their generation activities. In an attempt to address this situation, in January 2016, the Argentine Government unified and increased wholesale energy prices for all consumption in Argentina. As a result of this and other measures implemented by the Argentine government, investments have been made in conventional and renewable energy, moderately increasing the installed capacity during the last years. This increase in capacity has occurred both in thermal and renewable energy (wind and solar), the latter being enhanced by the renewable energy tenders, reaching 13% of the Argentine generation matrix in 2021. The demand supplied by renewable energies increased to 13.9% in 2022, to 14.3% in 2023, to 16.3% in 2024 and to 18.8% as of November 2025. In this way, the renewable energies sector continues to advance towards the goal of reaching 20% electricity supply from renewable sources by 2025, as established by Law No. 27,191. In 2025, new renewable projects started operating, incorporating 705 MW into Argentina’s electrical system and contributing a total of 7,436 to the energy matrix. Additionally, in 2025 a proposed bill was introduced to extend Law 27,191 until 2045, with the aim of consolidating investments, attracting private financing, and continuing to promote the energy transition in Argentina. On December 18, 2023, the Executive Branch published the Decree of Necessity and Urgency 55/2023 (DNU 55) in the Official Gazette, declaring that the national energy sector would be in a state of emergency – with regard to the generation, transportation and distribution of electric power under federal jurisdiction and the transportation and distribution of natural gas – until December, 31, 2024. Later, through Decree No. 1023/2024 the emergency of the national energy sector was extended until July 9, 2025, and further extended until July 9, 2026 by Decree of Necessity and Urgency 370/2025. Among other matters, DNU 55 launched a tariff review process for electric power and natural gas services that are subject to federal jurisdiction. In this regard, it should be noted that the tariff schedule resulting from the tariff review for the transportation and distribution of natural gas, will be enforced until July 9, 2025. As part of the tariff review, public hearings were held in February 2025. In addition, on April 30, 2025, the Argentine Executive Branch published new tariff schedules applicable to the transportation and distribution of electric power and natural gas services, which will apply from May 1, 2025 to April 30, 2030. This tariff adjustment will be implemented gradually and then applied in 30 monthly consecutive installments. Regarding energy prices, it should be noted that substantial increases were applied for residential and industrial users in 2024 and 2025 due to withdrawal of energy subsidies and the adjustment of the distribution value, and 17 Table of Contents further gradual increases are expected in 2026. Additionally, the ongoing construction of the second stage for the Gasoducto Néstor Kirchner (Néstor Kirchner Gas Pipeline) could alter the current status of the Argentine energy industry, particularly affecting the energy prices in ways that we are currently unable to predict. In this context, on December 29, 2025, the Argentine Executive Branch issued Decree 921/2025, which aims to overcome shortage of electricity and enhance infrastructure to address growing demand. Decree 921 establishes that the expansion works of the Argentine interconnection system—classified as a priority by Resolution 715/2025 of the Ministry of Economy—will be carried out by the private sector through National and International Public Tenders, under the terms of Law 17,520 on Public Works Concessions. It is estimated that the tender process for these expansion works will be carried out during the first half of 2026. Electricity generators may still not be able to guarantee the supply of electricity to distribution companies, which, in turn, could prevent these companies from experiencing continued growth in their businesses and could lead to failures to provide electricity to customers; and we may not have access to the gas necessary to maintain our cement production processes. Shortages and government efforts to respond to or prevent shortages may materially adversely impact the cost and supply of energy for our operations, which could materially adversely affect our operations and financial condition. Moreover, all of the locomotives we operate for our railroad segment are diesel-powered, and our fuel expenses are significant. If increases in fuel prices cannot be passed on to our customers through our tariffs, our operating margins could be materially and adversely affected. Fuel prices have historically been volatile and may continue to be volatile in the future. Fuel prices are subject to a variety of factors that are beyond our control, including, but not limited to, consumer demand for, and the supply of, oil, processing, gathering and transportation availability, price and availability of alternative fuel sources, weather conditions, natural disasters and political conditions. Public health threats or outbreaks of communicable diseases have had and may have an adverse effect on our operations and financial results We cannot ensure that there may not be any future public health threats and/or outbreaks of communicable diseases. In this sense, we are unable to estimate the economic and financial impact for our business, or the possibility of other economic effects on the stock market, foreign exchange rates and otherwise. Any such negative impact could result in a material adverse effect on our business, liquidity, financial conditions and results of operations as well as our ability to achieve our previously disclosed expectations for future years. We may be materially adversely affected if our transportation, storage and distribution operations are interrupted or are more costly than anticipated. Our operations are dependent upon the uninterrupted operation of transportation, storage and distribution of our cement products. Transportation, storage or distribution of our cement products could be partially or completely shut down, temporarily or permanently, as the result of any number of circumstances that are not within our control, such as: •disasters or catastrophic events; •extreme weather conditions; •hostilities or political uncertainty; •strikes or other labor difficulties; •acts of terrorism; •widespread illnesses or epidemics; •other disruptions in means of transportation; •higher logistics costs due to lack of availability of means of transport, greater bargaining power of logistics providers and/or significant increases in the cost of labor; and •potential impacts of the termination of the railway concession granted to Ferrosur Roca S.A. or of the eventual terms and conditions established for its continuation as a railway operator in the new operational modality that the National Government could implement. Please see “Item 3.D. The early termination of our railway concession may have a material adverse effect on our business". 18 Table of Contents In addition, we rely on third-party services providers for the transportation of our products to our customers. Our ability to service our customers at reasonable costs depends, in many cases, upon our ability to negotiate reasonable terms with carriers, including trucking companies. To the extent that third-party carriers were to increase their rates, we may be forced to pay these higher rates before we are able to pass such increases onto our customers, if at all. Any significant interruption at these facilities or an inability to transport our products to or from these facilities or to or from our customers for any reason would materially adversely affect us. Our business strategies require substantial capital and long-term investments, which we may be unable to fund competitively. To continue expanding our cement production capacity and distribution network, our business strategies require substantial capital investments, which we may finance through additional debt and/or equity financing. However, adequate financing may not be available or, if available, may not be available on satisfactory terms, including as a result of adverse macroeconomic conditions. We may be unable to obtain sufficient additional capital in the future to fund our capital requirements and our business strategy at acceptable costs. If we are unable to access additional capital on terms that are acceptable to us, we may not be able to fully implement our business strategy, which may limit the future growth and development of our business. If our need for capital were to arise due to operating losses, these losses may make it more difficult for us to raise additional capital to fund our expansion projects. The implementation of our growth strategies depends on certain factors that are beyond our control, including changes in the conditions of the markets in which we operate, actions taken by our competitors and laws and regulations in force in Argentina. The Company's results of operations and financial condition could be adversely affected by unfavorable economic conditions and the Company's eventual inability to access financing to fund its operations in the future. Our failure to successfully implement any part of our strategy may have a material adverse impact on us. Management’s plans to obtain sufficient funds to settle current liabilities may not be accomplished and hence we may have negative working capital in the near future. Our board of directors has the ultimate responsibility for liquidity risk management and has established an appropriate framework allowing our management to handle financing requirements for the short-, medium- and long-term. Weaker economic conditions could adversely affect our business, results of operations and financial condition. In addition, if we are unable to access the capital markets to finance our operations in the future, this could adversely affect our ability to obtain additional capital to grow our business. We are subject to risks related to litigation and administrative proceedings that could adversely affect our business and financial performance in the event of an unfavorable ruling. The nature of our business exposes us to litigation relating to product liability claims, labor, health and safety matters, environmental matters, regulatory, tax and administrative proceedings, governmental investigations, tort claims and contract disputes, among other matters. We have been and are subject to antitrust and tax proceedings or investigations including by the Argentine Antitrust Commission, or the CNDC (see “Item 8. Financial Information—Legal Proceedings—Antitrust Proceedings”). Litigation is inherently costly and unpredictable, making it difficult to accurately estimate the outcome of actual or potential litigation. Although we establish provisions as we deem necessary, the amounts that we reserve could vary significantly from any amounts we actually pay due to the inherent uncertainties in the estimation process. We cannot assure you that these or other legal proceedings will not materially affect our ability to conduct our business, or our financial condition or results of operations in the event of an unfavorable ruling. For instance, in 2018, two investors who claimed to have purchased our ADSs pursuant and/or traceable to our initial public offering, or IPO, commenced two separate putative class actions before U.S. courts on behalf of all persons and/or entities who purchased or otherwise acquired our ADSs pursuant and/or traceable to our prospectus and registration statement issued in connection with the IPO and, in the case of the Federal Class Action (described below), on behalf of all persons and/or entities who purchased our ADSs on the open market between November 2, 2017 and May 23, 2018, inclusive. The Federal Class Action was dismissed in 2020 and the dismissal is final, while the state putative class action was resolved through a settlement that received final court approval in 2024 and became full and final in 2025. The settlement did not include any admission of liability or wrongful conduct by us or the other defendants in the class action, 19 Table of Contents and included a release of all claims. See “Item 8.A. Consolidated Statements and Other Financial Information—Legal Proceedings—Securities Complaints Commenced Against Loma Negra under U.S. Jurisdiction.” We are subject to anti-corruption, anti-bribery, anti-money laundering and antitrust laws and regulations in Argentina and regulations in the United States and our internal policies and procedures might not be sufficient to ensure compliance with such laws and regulations. The United States Foreign Corrupt Practices Act (FCPA), the Argentine Anti-Money Laundering Law (Ley de Prevención del Lavado de Activos), the Argentine Corporate Criminal Liability Law (Ley de Responsabilidad Penal Empresaria) and other applicable anti-corruption laws prohibit companies and their intermediaries from offering or making improper payments (or giving anything of value) to government officials and/or persons in the private sector for the purpose of influencing them or obtaining or retaining business and require companies to keep accurate books and records and maintain appropriate internal controls. In particular, the Argentine Corporate Criminal Liability Law provides for the criminal liability of corporate entities for criminal offenses against public administration and transnational bribery committed by, among others, its attorneys-in-fact, directors, managers, employees, or representatives. In this sense, a company may be held liable and subject to fines and/or suspension of its activities if such offenses were committed, directly or indirectly, in its name, behalf or interest, the company obtained or may have obtained a benefit therefrom, and the offense resulted from a company’s ineffective control. Although we have a Compliance Program with internal policies and procedures designed to ensure compliance with applicable laws and regulations, potential violations of anti-corruption laws could be identified on occasion as part of our compliance and internal control processes. In case such issues arise, we plan to attempt to act promptly to learn relevant facts and take any appropriate remedial action to address the risk. Given the size of our operations and the complexity of the production chain, there can be no assurance that our internal policies and procedures will be sufficient to prevent or detect all inappropriate practices, fraud or violations of law by our employees, directors, officers, partners, agents and service providers or that such persons will not take actions in violation of our policies and procedures (or otherwise in violation of the relevant anti-corruption laws and sanctions regulations) for which we or they may be ultimately held responsible. If we or individuals or entities that are or were related to us are found to be liable for violations of applicable anti-corruption laws (either due to our own acts or our inadvertence, or due to the acts or inadvertence of others), we or other individuals or entities could face civil and criminal penalties or other sanctions, which in turn could have a material adverse impact on our reputation and business. Further, litigation or investigations relating to alleged or suspected violations of anti-corruption laws and sanctions regulations could be costly. We are also subject to antitrust laws in Argentina. Climate change and climate change legislation or regulations may adversely affect our business. The risks that climate change poses through environmental changes and acute, weather-related events continues to attract considerable public and scientific attention in the EU, the United States and other parts of the world. A number of governmental bodies have finalized, proposed, or are contemplating legislative and regulatory changes in response to the potential effects of climate change. For instance, on March 6, 2024, the SEC adopted final rules to require registrants to include extensive climate-related disclosures in registration statements and annual reports. Among other things, the SEC rules mandate disclosures on (i) Climate related risks that are reasonably likely to have a material effect on our business strategy, results of operations or financial condition; (ii) the actual and potential material impacts of identified climate-related risks on our business; (iii) any activities we have undertaken to mitigate or adapt to material climate-related risks; (iv) the extent of oversight and governance by our board of directors over climate-related risks and the role of management in assessing and managing these risks; (v) our processes for identifying, assessing, and managing material climate-related risks; and (vi) a qualitative description of how our financial statement estimates and assumptions have been materially influenced by climate-related risks and uncertainties, severe weather events, or disclosed climate-related targets or transition plans. On April 4, 2024 the SEC voluntarily stayed its climate-related disclosure rules pending completion of the Eighth Circuit Court of Appeal’s review of the rules, the SEC will “continue vigorously defending” the rules in court. However, on March 27, 2025, the SEC voted to end its legal defense of the climate disclosure rules, ending its previous legal posture. Although this action does not formally repeal the rules, it subjects them to the Eighth Circuit Court of Appeal's final decision. On September 12, 2025, the Eighth Circuit ordered the litigation to remain in abeyance until the SEC either reconsiders the rules through notice-and-comment rulemaking or renews its defense. While the SEC’s withdrawal does not formally repeal the rules, they remain subject to the Court's final decision should the SEC choose to 20 Table of Contents act. The adoption of these or similar rules in the future may necessitate significant changes in our reporting and operational practices, possibly leading to increased compliance costs and impacting our financial statements. The cement manufacturing process requires the combustion of large amounts of fuel and creates carbon dioxide as a by-product of the calcination process. Therefore, efforts to address climate change through federal, state, regional, EU and international laws and regulations requiring reductions in greenhouse gases (GHGs) can create economic risks and uncertainties for our business. Such risks could include the cost of purchasing allowances, emissions offsets or credits to meet GHG emission caps, the cost of installing equipment to reduce emissions to comply with GHG limits or required technological standards, decreased profits or losses arising from decreased demand for our goods and higher production costs resulting directly or indirectly from the imposition of legislative or regulatory controls. To the extent that financial markets view climate change and GHG emissions as a financial risk, this could have a material adverse effect on our cost of and access to capital. Given the uncertain nature of the actual or potential statutory and regulatory requirements for GHG emissions at the federal, state, regional, EU and international levels, we cannot predict the impact on our operations or financial condition or make a reasonable estimate of the potential costs to us that may result from such requirements. However, the impact of any such requirements, whether individually or cumulatively, could have a material economic impact on our operations. Climate change legislation and regulation concerning GHGs if implemented could have a material adverse effect on our financial condition, results of operations and liquidity. Climate change legislation and regulation may also adversely affect energy and electricity costs. There are ongoing international efforts to address GHG emissions. The United Nations and certain international organizations have taken action against activities that may increase the atmospheric concentration of GHGs. Such measures may result in increased costs to us for installation of new controls aimed at reducing GHG emissions, imposition of carbon taxes, purchase of credits or licenses for atmospheric emissions, and monitoring and registration of GHG emissions from our operations. These measures, if adopted in Argentina, could adversely affect our business, financial condition and results of operations. Changes in the investing and financing markets with respect to issuers with significant GHG emissions could also have such adverse effects. Climate change may include physical effects that may adversely affect our operations, such as disruption in production and supply chain distribution as a result of major storm events and shifts in regional weather patterns and intensities. Production and shipment levels for our businesses correlate with general construction activity, most of which occurs outdoors and, as a result, is affected by erratic weather patterns, seasonal changes, and other unusual or unexpected weather-related conditions, which can significantly affect our businesses. Environmental, health and safety regulation may adversely affect our business. The pollutants generated by cement producers are mainly dust and gas emissions from the use of fossil fuels. Our operations often involve the use, handling, disposal and discharge of hazardous materials into the environment and the use of natural resources. Most of our operations are subject to extensive environmental, health and safety regulations. In Argentina, regulations regarding gas emissions and air quality are enacted at both the national and provincial levels. We are required to obtain permits and licenses from governmental authorities for many aspects of our operations, and we may be required to purchase and install expensive pollution control equipment or to make operational changes to limit the actual or potential environmental, health and safety impacts of our operations to the environment and our employees. The Province of Buenos Aires, where our principal plants are located, requires that all production facilities have an environmental compliance certificate issued by the Ministry of Environment (former Provincial Organism for Sustainable Development), and similar certifications or approvals are required by relevant municipal or provincial authorities in the other jurisdictions in which we operate. As part of these requirements, local environmental authorities ordinarily make information requests to each of our plants relating to their compliance with environmental laws and regulations and, in the ordinary course of our business, we collaborate with such national and provincial environmental authorities in the conduct of their regulatory activities. We could be subject to administrative and criminal sanctions, including warnings, fines and closure orders for our failure to comply with these environmental regulations, which, among other things, limit or prohibit emissions or spills of toxic substances that we emit in connection with our operations. We also may be required to modify or retrofit our facilities at substantial cost in order to comply with waste disposal and emissions regulations. We are subject to inspection by environmental agencies in the various jurisdictions that we operate, which may impose fines, restrictions on our operations or other sanctions. In addition, we are subject to environmental laws that may require us to incur significant costs to mitigate any damage that a project may cause to the environment, which costs may adversely impact the viability 21 Table of Contents or projected profitability of the projects that we intend to implement. Moreover, any damage caused to the environment may oblige our company to pay compensation for damages. In addition, as a result of possible changes to environmental regulations, the amount and timing of our future environmental compliance expenditures may vary substantially from those we currently anticipate. Certain environmental laws impose liability on us for any and all consequences arising out of exposure to hazardous substances or the generation of environmental damage. Additionally, the Marrakesh Agreement established by the World Trade Organization (WTO), the Agreement on Technical Barriers to Trade, that recognizes that no country should be prevented from adopting measures necessary to ensure the quality of its exports, national security, protection of human and animal health, environmental protection, preservation of plants, and prevention of misleading practices. In this sense, The International Federation of Building and Wood Workers (IFBWW) - which brings together trade unions from the construction, wood, forestry, and related sectors - has developed a global campaign under the slogan "No more than 25Kg," basing it on the negative impact of manually carrying loads heavier than that weight on workers' health. Convention No. 127 of the International Labour Organization (ILO) contains provisions regarding the maximum weight of loads carried by a worker. These initiatives were locally reflected by the Resolution 54/2018 of the Secretary of Commerce. We cannot assure you that the costs we incur to comply with existing current and future environmental, health and safety laws, and liabilities that we may incur from past or future releases of, or exposure to, hazardous substances will not materially and adversely affect us. Compliance with mining regulations or the revocation of our authorizations, licenses and concessions could adversely affect our operations and profitability. We engage in certain mining operations as part of our cement production processes. These activities depend on authorizations and concessions granted by the Argentine governmental authorities or regulatory agencies. The extraction, mining and mineral processing activities are also subject to applicable laws and regulations, which change from time to time. Although we believe that we are in substantial compliance with applicable laws relating to these activities as well as the terms of our current authorizations and concessions, the effect of any future applicable regulatory changes regarding such matters on our mining activities or mining rights cannot presently be determined. In addition, if our authorizations and licenses are revoked, we may be unable to maintain or improve our cement production levels, which could adversely impact our results of operation and financial condition. Governmental agencies or other authorities may adopt new laws or regulations that are more stringent than existing laws or regulations or may seek to more stringently interpret or enforce existing laws and regulations that would require us to expend additional funds on environmental or other regulatory compliance or delay or limit our ability to operate as we intend. In addition, these actions could increase the costs associated with the renewal of our existing licenses and permits or the cost of seeking new licenses or permits. We cannot assure you that these additional costs will not be material or that our existing permits will be renewed. Our railway concession operates in a regulated environment, and measures taken by public authorities may impact our activities. Our transportation operation take place in a regulated environment. The Argentine federal government has the legal authority to regulate rail activities in the country (by means of the enactment of applicable laws and regulations). Therefore, actions taken by the public administration in general may affect the services rendered by us. Law No. 27,132 in effect since May 20, 2015, provides for important changes in the regulatory framework of the railway system and empowered Argentina’s federal government to renegotiate and, if necessary, terminate concessions currently in force. Pursuant to Decree No. 158/2021, published on March 12, 2021, the Federal Government imposed an update mechanism pursuant to which Ferrosur Roca would have to substantially increase the amount of the performance guarantee it had originally posted according to the concession contract (and updated in 2018 voluntarily). Ferrosur Roca has filed an administrative appeal against such Decree before the Argentine Executive Branch not only because the update is considered unreasonable but also because the Federal Government does not have the right to unilaterally modify the concession contract. On November 24, 2023, through Decree No. 601/2023 the appeal filed by Ferrosur Roca was rejected 22 Table of Contents by the previous administration. On January 2, 2024 Ferrosur Roca filed a new appeal against such decree. On November 19, 2025, by means of Decree No. 822/2025 Ferrosur Roca’s appeal was rejected and the company was informed that all administrative challenges had been exhausted and that it may appeal the decision before the competent court, until September 10, 2026. Ferrosur Roca is currently working on an appeal. We cannot be certain of the effects on the terms of our concession or any changes to the current regulatory framework that the competent authorities of the federal government may issue and whether these changes will adversely affect our results of operations. The early termination of our railway concession may have a material adverse effect on our business. Argentina’s railway concessions are subject to early termination in certain circumstances, including the competent authorities’ decision to regain control of the service or to terminate the concession for breach of contract. Upon termination of a concession, the leased or operated assets must revert to the federal government. The amount of compensation may not be sufficient to cover all the losses suffered by us as a result of such early termination. In addition, certain creditors may have priority with regard to such compensation. Likewise, upon termination, the competent authority may claim compensation alleging a purported breach of the concession contract. In addition, Law No. 27,132 (passed in April 2015), inter alia, established that the Argentine Executive Branch must adopt all necessary measures to recover the administration of railway infrastructure, provide for open access to the freight railroad transportation system and empowers the Ministry of Transport to terminate and renegotiate railway concession contracts. It also provided for the creation of a National Registry of Railroad Operators, which was established by Decree No. 1924/2015, within the purview of the National Commission of Transport Regulation (CNRT). The full implementation of the open access scheme entails the re-assumption by the Government of the administration of the railways infrastructure and, once in effect, would represent a significant change to the Argentine railway system. This regulatory change may benefit those sectors which are interested in operating railways in Argentina, as well as those that wish to transport commodities and other products through them. In November 2018, Decree No. 1027/2018 amended several provisions of Law No. 27,132, allowing for the renegotiation of railway concession contracts and the possibility of extending terms by up to ten years, and regulates concessionaire investments. The decree stipulates that the open-access scheme will be fully implemented once current railway concession agreements, including any extensions, have expired. On March 8, 2018, Ferrosur Roca applied for a ten-year extension to its concession. By March 20, 2019, the Ministry of Transport indicated that a Special Commission, as established by Decree No. 1027/2018, would oversee the renegotiation process, including analyzing the extension request to facilitate the open-access scheme. Resolution No. 1112/2018 appointed new Commission members by late 2018, but changes in membership delayed progress. Ferrosur Roca made its extension request conditional on renegotiation of concession terms, to address business impacts. On November 3, 2020, Ministry of Transport Resolution No. 248/2020 removed the Lobos-Bolívar branch from Ferrosur Roca's concession scope. Ferrosur Roca ratified its representatives and requested negotiation resumption, highlighting its commitment to progression despite setbacks. Resolution No. 219/2021, issued on March 29, 2021, established CNRT rules for the National Registry of Railroad Operators, granting operational capacity to Ferrosur Roca and other concessionaires. Upon open access implementation, registered operators will provide services irrespective of facility ownership. Registrants must fulfill specific service requirements, adhere to CNRT regulations and laws, and pay fees. Obligations include notifying CNRT of corporate changes and submitting annual financial statements. Performance compliance is monitored through annual CNRT reports. In accordance with Resolution No. 211/2021, published in the Official Gazette on June 28, 2021, the Ministry of Transport rejected the extension of the term of the concession requested by different companies such as Ferrosur Roca. In that sense, Ferrosur Roca’s concession was due to expire in March 2023. Later on, the CNRT approved the registration of Ferrosur Roca as “Railway Operator” in the National Register of Railway Operators (ReNOF, as per its acronym in Spanish) by the enactment of Disposition No. 122/2022, published in the Official Gazette on February 25, 2022. 23 Table of Contents On December 28, 2022, the Argentine Ministry of Transport issued Resolution No. 960/2022, extending the term of the concession by 18 months as of March 10, 2023, until September, 2024. Such term was again extended by the Ministry of Economy on October, 2024 by means of Resolution No. 991/2024 until September 10, 2025. Subsequently, through Resolution 52/2025, the Secretariat of Transportation extended the concession term until September 10, 2026, or until a new railway concession for the General Roca line is awarded, whichever occurs first. However, such extension may be revoked at any time, with or without cause, and Ferrosur Roca will not be entitled to receive or claim any compensation if the decision to revoke the concession is taken before September 2026. On February 11, 2025, the Ministry of Economy, through Resolution No. 99/2025, ordered the removal of part of Branch 38, from Kilo Cinco to Sola “A” Station, from the concession granted to Ferrosur Roca . As a result, the railway infrastructure for this section was transferred to Administración de Infraestructuras Ferroviarias (ADIF), a national public sector company operating within the Secretariat of Transportation of the Ministry of Economy. This removal could adversely affect our concrete operations at the Sola plant. In addition, on February 10, 2025, the Argentine Executive Branch issued Decree 67/2025 authorizing the total privatization of Belgrano Cargas y Logística S.A., (the government owned and operated freight railway line) through the vertical disintegration and separation of the activities and assets of each of its business units through the celebration of public works concession contracts for the railway tracks and workshops, together with their adjacent properties, and the sale of the rolling stock through a public auction. Later, on July 24, 2025, the Ministry of Economy issued Resolution 1049/2025 which started the privatization process of Belgrano Cargas y Logística S.A and ordered the Secretariat of Transportation to adopt the necessary measures to move forward with the process. Although these measures do not directly affect our concession, they demonstrates the Argentine government’s willingness to implement significant changes to railway infrastructure policies and concession frameworks. As of the date of this annual report, we cannot guarantee that the Argentine authorities will not terminate our railway concessions prior to the stated terms or that they will extend the term of the railway concession upon the current expiration fixed on September 2026. Furthermore, we cannot guarantee that the Argentine authorities will actually implement the open access scheme nor the mechanism and terms in which the rolling stock will be leased. Any such action by the Argentine authorities could have a material adverse effect on our business, financial condition and results of operations. For additional information related to Ferrosur Roca’s railway concession, See “Item 4.B. Information on the Company—Business Overview—Ferrosur Roca”. Our estimates of the volume and grade of our limestone deposits could be overstated, and we may not be able to replenish our reserves. Our limestone reserves described in this annual report constitute our estimates based on evaluation methods generally used in our industry and on assumptions as to our production. Our proven and probable reserve estimates are based on estimated recoverable tons. A “qualified person” (as defined in Regulation S-K 1300) employed by us reviewed our limestone reserves for 2025, confirming no material changes necessitating updates in our annual filing, as defined by Regulation S-K 1300. We did not employ independent third-parties to review reserves over the five-year period ended December 31, 2025. Our mineral reserves data are prepared by our engineers and geologists and are subject to further review by our corporate staff. Moreover, there are numerous uncertainties inherent in estimating quantities of reserves and in projecting potential future rates of mineral production, including many factors beyond our control. The calculations of mineral reserves are estimates and depend upon geological interpretation and statistical inferences or assumptions drawn from drilling and sampling analyses. Reserve engineering involves estimating deposits of minerals that cannot be measured precisely, and the accuracy of any reserve estimate is a function of the quality of available data, as well as engineering and geological interpretation and judgment. These estimates are also subject to uncertainty due to factors that include the inherent variability of the deposit and recoverability of usable material in the mining process. As a result, we cannot assure investors that our limestone reserves will be recovered or that they will be recovered at the rates we anticipate. We may be required to revise our reserve and mine life estimates based on our actual production and other factors. These estimates and assumptions could change significantly in the future and could adversely affect our financial position, results of operations or cash flows. If our limestone reserves are lower than our estimates, this may have a material adverse effect on us, particularly if as a result we have to purchase limestone from third-party suppliers, and it could also adversely affect the 24 Table of Contents value of your investment in our securities or subject us to liability under U.S. federal securities laws in the form of SEC enforcement actions or private lawsuits. Our business is subject to a number of operational risks, which may adversely affect our business, financial condition and results of operations. Our cement business is subject to several industry-specific operational risks, including accidents, natural disasters, labor disputes and equipment failures. Such occurrences could result in damage to our production facilities, and equipment and/or the injury or death of our employees and others involved in our production process. Moreover, such accidents or failures could lead to environmental damage, loss of resources or intermediate goods, delays or the interruption of production activities and monetary losses, as well as damage to our reputation. Any prolonged and/or significant disruption to our production facilities, whether due to repair, maintenance or servicing, governmental or administrative actions, regulatory issues, civil unrest, industrial accidents, unavailability of raw materials such as energy, mechanical equipment failure, human error, natural disasters, cyberattacks to our systems, public health threat or otherwise, could disrupt and adversely affect our operations. Additionally, any major or sustained disruptions in the supply of utilities such as water or electricity or any fire, flood or other natural calamities or communal unrest or acts of terrorism or disease outbreaks may disrupt our operations or damage our production facilities or inventories and could adversely affect our business, financial condition and results of operations. Our insurance may not be sufficient to cover losses from these events, which could adversely affect our business, financial condition and results of operations. Our rail transportation and handling of cargo also exposes us to risks of catastrophes, mechanical and electrical failures, collisions and loss of assets. Fires, explosions, fuel leaks and other flammable products as well as other environmental events, cargo loss or damage, railroad, cargo loading and unloading terminal, accidents, business interruptions due to political events as well as labor claims, strikes, adverse weather conditions and natural disasters, such as floods, may result in the loss of revenues, assumption of liabilities or cost increases. Moreover, our operations may be periodically affected by landslides and other natural disasters. We typically shut down our facilities to undertake maintenance and repair work at scheduled intervals. Although we schedule shutdowns such that not all of our facilities are shut down at the same time, the unexpected shut down of any facility may nevertheless affect our business, financial condition and results of operations from one period to another. In addition, key equipment at our facilities, such as our mills and kilns, may deteriorate sooner than we currently estimate. Such deterioration of our assets may result in additional maintenance or capital expenditures, and could cause delays or the interruption of our production activities. If these assets do not generate the cash flows we expect, and we are not able to procure replacement assets in an economically feasible manner, our business, financial condition and results of operations may be materially and adversely affected. Our insurance coverage may not cover all the risks to which we may be exposed. We face the risks of loss and damage to our products, property and machinery due to fire, theft and natural disasters such as floods. Such events may cause a disruption to or cessation of our operations. Our insurance may not be sufficient to cover losses from these events, which could adversely affect our business, financial condition and results of operations. We also face risks related to cybersecurity threats; however, as of December 31, 2025, our insurance does not cover losses associated with cybersecurity risks. If our losses exceed our insurance coverage, or if we are not covered by our insurance policies, we may be liable for any shortfalls or losses. Our insurance premiums may also increase substantially because of such claims. Such circumstances could have a material adverse effect on our business, liquidity, financial condition and results of operations. Our success depends on key members of our management. Our success depends largely on the efforts and strategic vision of our executive management team and board of directors. The loss of the services of some or all of our executive management or members of our board of directors could have a material adverse effect on our business, financial condition and results of operations. The execution of our ongoing business plan also depends on our ongoing ability to attract and retain additional qualified employees. For a variety of reasons, particularly with respect to the competitive environment and the availability of skilled labor, we may not be successful in attracting and retaining the personnel we require. If we are unable 25 Table of Contents to hire, train and retain qualified employees at a reasonable cost, we may be unable to successfully operate our business or capitalize on growth opportunities and, as a result, our business, financial condition and results of operations could be adversely affected. The introduction of substitutes for cement in the markets in which we operate and the development of new construction techniques could have a material adverse effect on us. Materials such as plastic, aluminum, ceramics, glass, wood and steel can be used in construction to substitute cement. In addition, other construction techniques, such as the use of dry wall, and the integration of new technologies in the construction industry, such as 3-D printing, mini-mills and mobile plants, and changes in housing preferences could decrease the demand for cement and concrete. In addition, research aimed at developing new construction techniques and modern materials and digitalizing the construction industry may be introduced in the future that could reduce the demand for and prices of our products. The use of substitutes for cement such as recycled concrete and asphalt which are increasingly being used in a number of our markets, particularly urban markets, could cause a significant decrease in the demand and prices for our cement products and have a material adverse effect on our business, financial condition, liquidity and results of operations. We are subject to restrictions due to our non-controlling interests in certain of our consolidated subsidiaries. We conduct some of our business through subsidiaries. In some cases, other shareholders hold non-controlling interests in these subsidiaries. Non-controlling shareholders’ interests may not always be aligned with our interests and, among other things, could result in our inability to implement organizational efficiencies and transfer cash and assets from one subsidiary to another in order to allocate assets most effectively. Changes in labor laws or in case law interpretations of labor laws in Argentina that tend to favor employees could negatively affect our results of operations. In December 2023, the Argentine Executive Branch issued the Urgent and Necessary Decree No. 70/2023 (“DNU”, for its acronym in Spanish) by which significant changes to labor regulations were made (eliminating fines for lack of registration of employment, flexible regulations for employees, contractors, and outsourcing models, among others). However, the two union confederations in Argentina (the General Confederation of Labor -“CGT”- and Argentine Workers’ Central Union -“CTA”-, entities to which all trade unions are associated) presented a challenge against the DNU before the National Labor Courts. The resolution by the National Supreme Court is pending. Thus, labor chapter of the DNU is still suspended. However, the Bases Law incorporated some of the changes introduced by the DNU, such as the elimination of the very expensive labor fines for lack or deficient registration of employment, in addition to certain new modifications. The changes instituted by the Bases Law aim to make it easier for private sector employers to hire and manage their workforce. Among others, these changes aim to reduce the contingencies and economic exposure related to labor claims in general and to those made by third-party employees in particular. Risks may not be ruled out because the Bases Law is very recent and the courts’ reactions and approaches is still unknown. So far, labor courts have not challenged the constitutionality of the Bases Law, but they have maintained their position of issuing rulings that are more favorable to the employees. Accordingly, many labor courts have replaced the labor fines eliminated by the Bases Law with awards of damages. The position of the Milei administration is generally favorable to the private sector, seeking to promote economic growth and industrial investment. In line with this approach, the National Congress passed Law No. 27,802, entered in force during the first weeks of March 2026, which further reforms labor legislation by modifying basic principles of labor law. This amendment is expected to encourage the creation of private employment, reduce labor litigation and give employers more foreseeability regarding labor costs and relationships. The enforcement of the reform may be uncertain and its enforceability may be challenged in court. In the past, the Argentine government has introduced laws, regulations and decrees requiring private companies to maintain certain minimum wage standards and provide specific benefits to employees. We cannot guarantee that the Argentine government will not take measures that will increase wages or require us to provide additional benefits that result in an increase in our costs and expenses, although this is not expected to happen given the current policies of the Milei administration. 26 Table of Contents Failures in our information technology systems and information security (cybersecurity) systems can adversely impact our operations and reputation. Our operations are to some extent dependent on information technology and automated operating systems to manage or support our operations. The proper functioning of these systems is critical to the efficient operation and management of our business. Our systems may be vulnerable to damage, disruption or intrusion caused by circumstances beyond our control, such as physical or electronic theft, catastrophes, power outages, natural disasters, computer system or network failures, viruses or malware, unauthorized access and cyber-attacks. In addition, these systems may require modifications or upgrades as a result of technological advancements or the growth of our business. We constantly evaluate the risks we face and, as a result, we reinforce our IT infrastructure by implementing new technologies and solutions to assist in the prevention of potential cyber-attacks, as well as protective measures and contingency plans in the event of an attack. Our manufacturing operations rely on Operational Technology (OT) and industrial control systems (ICS) that are strictly segmented from our corporate network and remain disconnected from the public internet. While this air-gapped architecture significantly reduces our exposure to external cyber-attacks, our production remains vulnerable to internal threats, unauthorized physical access, or compromised maintenance devices. Any corruption or failure in these isolated systems could result in unplanned production downtime or safety incidents, materially impacting our operational results and financial condition. Loma Negra has developed a Cybersecurity Incident Response Plan that provides a structured and organized framework to effectively and efficiently address cybersecurity incidents by analyzing the potential impact, containment of the attack, eradication of the threat and recovery all while ensuring operational continuity. We have also developed a Communication Plan to enable information flow among internal and external stakeholders in the event of an incident. Over the past year, we have reinforced our Awareness Plan, focusing on training our employees on cybersecurity risks and threats as well as instructing them on how to respond to a cybersecurity incident, whether it involves or affects IT resources or the devices used to access Loma Negra's IT systems. During 2025, our focus was on streamlining the reporting process for any detected anomalies. To date, we have not detected, and our external service providers have not informed us of, any relevant event that has materially damaged, interrupted or caused an intrusion in our systems. Any significant data leakage or theft of information could affect our compliance with data privacy laws and harm our relationship with our employees, customers and suppliers, and also adversely impact our business, financial condition and results of operation. As of December 31, 2025, our insurance does not cover any risk associated with any cybersecurity risks. In addition, any significant disruption to our systems could adversely affect our business, financial condition and results of operations. Risks Relating to Our Ordinary Shares and the ADSs The market price of our ADSs may fluctuate significantly, and you could lose all or part of your investment. Volatility in the market price of our ADSs may prevent you from being able to sell your ADSs at or above the price you paid for them. The market price and liquidity of the market for our ADSs may be significantly affected by numerous factors, some of which are beyond our control and may not be directly related to our operating performance. The market price of our ADSs increased by 8% and 68% in 2025 and 2024, respectively. The variation in value may be affected by the following factors: •actual or anticipated changes in our results of operations, or failure to meet expectations of financial market analysts and investors; •investor perceptions of our prospects or our industry; •operating performance of companies comparable to us •increased competition in our industry; •inflationary trends; •new laws or regulations or new interpretations of laws and regulations applicable to our business; •general economic trends in Argentina; 27 Table of Contents •departures of management and key personnel; •the trading volume of our ADSs; •catastrophic events, such as earthquakes and other natural disasters; •widespread illnesses or epidemics; •developments and perceptions of risks in Argentina and in other countries; and •a change in control, including as a result of changes in the shareholders composition of our indirect controlling shareholder. Market fluctuations, as well as general political and economic conditions in the markets in which we operate, such as recession or currency exchange rate fluctuations, may also adversely affect the market price of our ordinary shares and the ADSs. Although our ADSs listed on the New York Stock Exchange are U.S. dollar-denominated securities, they do not eliminate the currency risk associated with an investment in an Argentine company. Following periods of volatility in the market price of a company’s securities, that company may often be subject to securities class-action litigation. This kind of litigation may result in substantial costs and a diversion of management’s attention and resources, which could have a material adverse effect on our business, results of operations and financial condition. The relative volatility and illiquidity of the Argentine securities markets may substantially limit your ability to sell shares underlying the ADSs at the price and time you desire. Investing in securities that trade in emerging markets, such as Argentina, often involves greater risk than investing in securities of issuers in the United States. The Argentine securities market is substantially smaller, less liquid, more concentrated and can be more volatile than major securities markets in the United States and is not as highly regulated or supervised as some of these other markets. There is also significantly greater concentration in the Argentine securities market than in major securities markets in the United States. Accordingly, although you are entitled to withdraw the shares underlying the ADSs from the ADR facility, your ability to sell such shares at a price and time at which you wish to do so may be substantially limited. Furthermore, new capital controls imposed by the Argentine Central Bank could have the effect of further impairing the liquidity of the BYMA by making it unattractive for non-Argentines to buy shares in the secondary market in Argentina. See “Item 10.D. Additional Information—Exchange Controls”. Interpretation of Argentine tax laws may adversely affect the tax treatment of our ordinary shares and the ADSs. Argentine income tax law provides that the income resulting from the sale, exchange or other transfer of shares and other securities is subject to tax at a rate of 15% for Argentine resident individuals or a sliding scale from 25% to 35%, depending on the accumulated net income obtained during the given year, for Argentine companies; in addition, dividend distributions to Argentine resident individuals or non-Argentine residents are subject to a 7% additional tax, as per the amendment to the Income Tax Law by Law No. 27,630. These corporate rates apply to fiscal years starting as from January 1, 2021, and the tax on dividends are applicable for fiscal years starting as from January 1, 2018. Argentine residents are exempt from the tax derived from the sale, exchange or other transfer of shares in case of shares issued by Argentine companies which are listed in capital markets authorized by the CNV and have authorization for public offering by the CNV as long as such transactions are carried out through stock exchanges or stock markets authorized by the CNV. Income obtained by non-Argentine residents from the sale, exchange or other transfer of shares is subject to income tax rate of 15% of the net income or 13.5% of the gross consideration, to the extent such non-Argentine residents do not reside, and the funds invested do not derive from, a non-cooperative jurisdiction as defined by the Income Tax Law and the “black list” included in its regulatory decree; otherwise, the applicable withholding rates would be 31.5% of the gross consideration. In case of a sale or other transfer between two non-Argentine residents, the income tax must be paid by the seller by means of the following mechanisms: (a) if the seller has a legal representative in Argentina, or appoints someone in Argentina for purposes of paying the tax, then such representative or appointed party must pay the tax; and (b) if the seller does not have a legal representative in Argentina and does not appoint someone, then the seller itself must pay the tax through an international wire transfer . Argentine income tax law also exempts non-Argentine residents from the payment of the income tax on the sales, exchanges or other transfers of shares issued by Argentine companies which are listed in capital markets authorized by the CNV and have authorization for public offering by the CNV as long as such transactions are carried out through 28 Table of Contents stock exchanges or stock markets authorized by the CNV and to the extent that the seller does not reside in, and the funds invested do not come from, non-cooperative jurisdictions, as defined by the Income Tax Law and the “black list” included in its regulatory decree. Also, non-residents are exempted from the income tax deriving from the sale or other kind of disposition regarding ADSs which underlying security are shares issued by Argentine companies that comply with the requirements described above. The holders of our ordinary shares and the ADSs are encouraged to consult with their tax advisers as to the particular Argentine income tax consequences of owning our ordinary shares and ADSs. See “Item 8. Financial Information—Dividends and Dividend Policy” and “Item 10.E Additional Information—Taxation—Material Argentine Tax Considerations”. Restrictions on transfers of foreign exchange and the repatriation of capital from Argentina may impair our ability to pay dividends and distributions on, and the proceeds of any sale of, the shares underlying the ADSs. On September 1, 2019, the Argentine government issued Executive Decree No. 609/19 (as amended) which, inter alia, reinstated certain foreign currency exchange restrictions. The Decree was further regulated, amended and complemented by several regulations issued by the BCRA (included, but not limited to, Communication “A” 6844, as further amended, supplemented and restated). Since then, the Argentine government has implemented monetary and foreign exchange control measures that included restrictions on the transfer of funds abroad, including dividends, without prior approval by the BCRA or fulfillment of certain requirements. However, starting on January 17, 2020 and until fiscal years beginning on or after January 1, 2025, Argentine companies were subject to quantitative limitations and specific conditions in order to access the foreign exchange market for payment of dividends to non-resident shareholders, including limits linked to new foreign direct investment contributions. For example, Argentine companies were only allowed to transfer funds abroad in order to pay annual dividends only to foreign shareholders and the depositary for the benefit of the American Depositary Shares, or ADS holders, in an amount that (including the amount of the payment being made at the time of the access) did not exceed 30% of the value of new capital contributions of foreign direct investments made to local companies and the funds must be transferred to Argentina and sold for pesos through the foreign exchange market as from such date. In case of non-resident shareholders, the total amount to be paid through the FX Market could not exceed the corresponding amount denominated in pesos that was determined by the shareholders’ meeting. According to BCRA Communication “A” 8226, dated April 11, 2025, Argentine companies shall have access to the foreign exchange market to purchase and transfer foreign currency abroad for the payment of profits and dividends to non-resident shareholders pursuant to certain provisions set forth in foreign exchange regulations. These distributions must correspond to distributable profits derived from realized earnings arising from regular and audited annual financial statements for fiscal years beginning on or after January 1, 2025. Access to the foreign exchange market for the payment of dividends corresponding to prior fiscal years (such as those corresponding to the 2024 fiscal year or earlier) or not meeting the applicable regulatory conditions may still require prior approval of the BCRA. In addition to the formal exchange controls and regulations, the Argentine Central Bank has exercised in the past a de facto prior approval power for certain foreign exchange transactions otherwise authorized to be carried out under the applicable regulations, such as dividend payments or repayment of principal of intercompany loans as well as the import of goods, by means of regulating the amount of foreign currency available to financial institutions to conduct such transactions.See “Item 10.D. Additional Information—Exchange Controls”. Payments of cash dividends and distributions, if any, will be made in pesos, although we reserve the right to pay in other currency or in kind to the extent permitted by applicable law. Subject to applicable law, the ADS depositary will convert such dividends received in pesos into U.S. dollars and pay such amount to holders of ADSs, net of any dividend distribution fees, ADS depositary's fees and expenses, currency conversion expenses and taxes or governmental charges, if any. In the event that the ADS depositary is unable to convert immediately the amount in pesos received as cash dividends or the amount in kind into U.S. dollars the amount of U.S. dollars payable to holders of ADSs may be adversely affected by depreciation of the peso or the fluctuation of the value of the payment in kind. In case the depositary for the ADSs is prevented from converting pesos received in Argentina into U.S. dollars for the account of the ADS holders by any regulatory and/or de facto restrictions that may be applicable, the deposit 29 Table of Contents agreement allows the depositary to distribute the foreign currency only to those ADS holders to whom it is practicable to do so. If the exchange rate fluctuates significantly during a time when the depositary cannot convert the foreign currency, you may lose some or all of the value of the dividend distribution. Your voting rights with respect to the shares are limited. Holders may exercise voting rights with respect to the shares underlying ADSs only in accordance with the provisions of the deposit agreement. There are no provisions under Argentine law or under our by-laws that limit ADS holders’ ability to exercise their voting rights through the depositary with respect to the underlying shares. However, there are practical limitations upon the ability of ADS holders to exercise their voting rights due to the additional procedural steps involved in communicating with such holders. For example, Capital Markets Law No. 26,831 ("LMC") requires us to notify our shareholders by publications in certain official and private newspapers between 20 and 45 days in advance of any shareholders’ meeting. ADS holders will not receive any notice of a shareholders’ meeting directly from us. In accordance with the deposit agreement, we will provide the notice to the depositary, which will in turn, as soon as practicable thereafter and subject to legal limitations, provide to each ADS holder upon the terms of the deposit agreement: •the notice of such meeting; •voting instruction forms; and •a statement as to the manner in which instructions may be given by holders (including an express indication that such instructions may be deemed given upon the terms specified below). To exercise their voting rights, ADS holders must then provide instructions to the depositary how to vote the shares underlying ADSs. Because of the additional procedural step involving the depositary, the process for exercising voting rights will take longer for ADS holders than for holders of shares. If we timely request the depositary to distribute voting materials to the ADS holders and the depositary does not receive timely voting instructions from an ADS holder on or before the date established by the depositary for such purpose, the depositary shall deem such ADS holder to have instructed the depositary to give a discretionary proxy to a person designated by our board of directors with respect to the deposited securities represented by the holder’s ADSs. The cutoff time for ADS holders to provide voting instructions to the depositary bank is typically up to two business days prior to the cut-off date to vote shares in Argentina so as to enable the depositary bank to tally the ADS voting instructions received from ADS holders and to provide the corresponding voting instructions at the share level in Argentina through the custodian of the shares represented by ADSs. Except as described in this annual report, holders will not be able to exercise voting rights attaching to the ADSs. Holders of ADSs who wish to propose matters or vote on any matters directly should cancel their ADSs and withdraw their underlying ordinary shares to attend and vote at the shareholders meetings. If we do not file or maintain a registration statement and no exemption from the Securities Act registration is available, holders of ADSs may be unable to exercise preemptive rights with respect to our ordinary shares, as a result of which your investment may be diluted. Under the Argentine General Companies Law, if we issue new shares as part of a capital increase, our shareholders will generally have the right to subscribe for a proportional number of shares to maintain their existing ownership percentage, which is known as preemptive rights. However, pursuant to the LMC, our shareholders will not be entitled to the right to subscribe for the unsubscribed shares at the end of a preemptive rights offering, known as accretion rights. We may not be able to offer our ordinary shares to holders of ADSs residing in the U.S., or U.S. holders, pursuant to preemptive rights granted to holders of our ordinary shares in connection with any future issuance of our ordinary shares unless a registration statement under the Securities Act is effective with respect to these 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 ordinary shares, and we cannot assure you that we will file or maintain any such registration statement. If we do not file and maintain a registration statement and there is no exemption from registration, the depositary for our ADSs, may attempt to sell the preemptive rights and provide holders of our ADSs with their pro rata share of the net proceeds from any such sale. However, these preemptive rights may expire if the depositary does not sell them on a timely basis, and holders of ADSs will not receive any benefit from such preemptive rights. Even if a registration statement were effective, we may decide to not extend any preemptive or 30 Table of Contents subscription rights to U.S. Persons (as defined in Regulation S under the Securities Act) that are holders of our ordinary shares and holders of ADSs. Furthermore, the equity interest of holders of shares or ADSs located in the United States may suffer dilution of their interest in us upon future capital increases. We are entitled to amend and supplement the deposit agreement and to change the rights of ADS holders under the terms of such agreement, without the prior consent of the ADS holders. We are entitled to amend and supplement the deposit agreement and to change the rights of the ADS holders under the terms of such agreement, without the prior consent of the ADS holders. Any amendment that imposes or increases any fees, charges or expenses (other than stock transfer or other taxes and other governmental charges, transfer or registration fees, a transaction fee per cancellation request (including through SWIFT, telex or facsimile transmission), applicable delivery expenses or other such fees, charges or expenses), or that shall otherwise prejudice any substantial existing right of ADS' holders, shall become effective 30 days after notice of such amendment shall have been given to the ADS' holders. Any amendments required by new laws, rules or regulations adopted by governmental body or regulatory body, may become effective before a notice of such amendment or supplement is given to the holders of the ADS. The substantial share ownership position of our controlling shareholder will limit your ability to influence corporate matters. Our controlling shareholder beneficially owns 52.14% of our outstanding ordinary shares as of the date of this annual report. As such, our controlling shareholder has the ability to determine the outcome of substantially all matters submitted for a vote to our shareholders and thus exercise control over our business policies and affairs, including, among others, the following: •the composition of our board of directors and, consequently, any determinations of our board with respect to our business direction and policy, including the appointment and removal of our executive officers; •determinations with respect to mergers, other business combinations and other transactions, including those that may result in a change of control; •whether dividends are paid or other distributions are made and the amount of any such dividends or distributions; •cause us to issue additional equity securities; •whether we limit the exercise of preemptive and accretion rights to holders of our ordinary shares in the event of a capital increase to the extent and terms permitted by the applicable law; •sales and dispositions of our assets; and •the amount of debt financing that we incur. Furthermore, our controlling shareholder’s interests may conflict with your interests as a holder of ordinary shares or ADSs, and it may take actions that might be desirable to it but not to other shareholders and may be able to prevent other shareholders, including you, from blocking these actions or from causing different actions to be taken. Also, our controlling shareholder may prevent change of control transactions that might otherwise provide you with an opportunity to dispose of or realize a premium on your investment in our ADSs. We cannot assure you that our controlling shareholder will act in a manner consistent with your interests. See ‘Item 7.A. Major Shareholders — Significant Changes in Percentage Ownership’. The share ownership position of our principal shareholders may limit your ability to influence corporate matters, and changes in the indirect ownership of our controlling shareholder may create additional uncertainty regarding how control is exercised over us. Our controlling shareholder, InterCement Trading e Inversiones Argentina, S.L., beneficially owns 52.14% of our outstanding ordinary shares and therefore has the ability to control the outcome of substantially all matters submitted to a vote of our shareholders, including the election of directors and the approval of significant corporate transactions. As a result, holders of our ordinary shares and ADSs have limited ability to influence our business and affairs, and the interests of our controlling shareholder may conflict with the interests of our minority shareholders. In particular, our controlling shareholder may be able to (and may choose to) cause us to take actions that it believes are in its interests (including with 31 Table of Contents respect to our dividend policy, financing decisions, capital allocation and the pursuit, timing or terms of potential strategic transactions), which may not be aligned with the interests of holders of our ordinary shares and ADSs. While InterCement Trading e Inversiones Argentina, S.L. remains our direct controlling shareholder and continues to hold the same stake, the indirect ownership of our indirect controlling shareholder has changed. As publicly disclosed, one indirect shareholder holds approximately 38.7%, a second one holds approximately 26.7%, and a third one holds approximately 24.0% of the relevant upstream ownership interests, and they have stated that there is no shareholders’ agreement or other agreement among them. As a result, no single indirect shareholder controls our indirect controlling shareholder. Even in the absence of an agreement, these indirect shareholders may each seek to influence the strategy, governance, and decision-making of our controlling shareholder and the manner in which it exercises its voting power in our Company, and their interests may differ from each other and from the interests of our Company and our minority shareholders. This ownership structure may also increase the risk of additional changes in the indirect ownership of our controlling shareholder, including through transfers by one or more of its indirect shareholders, which could result in changes in influence over our Company and create additional uncertainty for investors. The market’s perception of the risks associated with our concentrated ownership structure and changes in the indirect ownership of our controlling shareholder may adversely affect the trading price and liquidity of our ordinary shares and ADSs. The pledge of a portion of our shares by InterCement Trading e Inversiones Argentina S.L., our controlling shareholder, may lead to market fluctuations and potential change of control. On June 4, 2020, Intercement Trading e Inversiones S.A. and InterCement Trading e Inversiones Argentina S.L. (as pledgors) pledged all of the shares in Loma Negra then held by InterCement Trading e Inversiones S.A. (304,233,740 ordinary shares currently representing 52.14% of our total capital stock) in favor of Trustee Distribuidora de Títulos e Valores Mobiliários Ltda., as collateral for certain debenture obligations of Intercement Brasil S.A. and InterCement Participações S.A. Following a subsequent transfer of shares, InterCement Trading e Inversiones Argentina S.L. became the sole pledgor under the pledge. In addition, as a result of the judicial reorganization, the pledge currently secures only debenture obligations of InterCement Brasil S.A. and its guarantors (including our indirect controlling shareholder). See “Risks Relating to Our Former Indirect Controlling Shareholder—The development of the judicial reorganization process of our indirect controlling shareholder, including a potential marketing process of our Company, may have an adverse effect on our business, financial condition or results of operations and/or the market price of our ordinary shares or ADSs.” On March 31, 2026, we were informed by InterCement Participações S.A., our indirect controlling shareholder, that the parties to the pledge agreement had executed an amendment thereto in order to reflect a new priority ranking structure resulting from its judicial reorganization plan, the court approval of which we previously disclosed on our report on Form 6-K dated December 10, 2025. We cannot assure you that InterCement Brasil S.A. and its guarantors (including our indirect controlling shareholder) will be able to satisfy the restructured debentures obligations or that the pledged shares will not be foreclosed upon. In the event of a foreclosure on the pledged shares, a change of control of the Company would occur, which could, among other things, cause significant volatility in the trading price of our ordinary shares and ADSs, reduce investor confidence, and adversely affect our ability to access the capital markets on favorable terms, or at all. Any of the foregoing could have a material adverse effect on our business, financial condition, results of operations, and the trading price of our securities. Our status as a “foreign private issuer” and as a “controlled company” allows us to follow alternate standards to the corporate governance standards of the NYSE, which may limit the protections afforded to investors. The NYSE’s rules require domestic listed companies that are not “controlled companies” to have, among other requirements, a majority of their board of directors be independent and to have independent director oversight of executive compensation, nomination of directors and corporate governance matters. As a “foreign private issuer”, we are permitted to, and we will, follow home country practice in lieu of the above requirements. Argentine 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/corporate governance committee. In addition, under the NYSE rules, a “controlled company” in which over 50% of the voting power is held by an individual, a group or another company is also not required to have a majority of its board of directors be independent 32 Table of Contents directors and to have a compensation committee or a nominating/corporate governance committee, or to have such committees be composed entirely of independent directors. We currently follow certain Argentine practices concerning corporate governance and intend to continue to do so. As a “controlled company”, we are eligible to, and, in the event we no longer qualify as a “foreign private issuer”, we intend to, elect not to comply with certain of the NYSE corporate governance standards, including the requirement that a majority of directors on our board of directors are independent directors and the requirement to maintain a compensation and a nominating/corporate governance committee consisting entirely of independent directors. Accordingly, holders of our ADSs will not have the same protections afforded to shareholders of companies that are subject to all NYSE corporate governance requirements and our status as a “foreign private issuer” and a “controlled company” may adversely affect the trading price for our ADSs. For more information, see “Item 16.G. Corporate Governance”. We have incurred and will continue to incur increased costs related to operating as a public company, and our management will be required to devote substantial additional time to new compliance initiatives and corporate governance practices. We are subject to the reporting requirements of the Exchange Act, the Sarbanes-Oxley Act, the Dodd-Frank Wall Street Reform and Protection Act, as well as rules adopted, and to be adopted, by the SEC and the NYSE. Our management is required to certify financial and other information in our quarterly and annual reports, as well as to establish and evaluate periodically disclosure controls and procedures and internal control over financial reporting. Additionally, in light of our loss of “emerging growth company” status as of December 31, 2022, we can no longer take advantage of an extended transition period for complying with new or revised accounting standards and must obtain an annual auditor attestation on the effectiveness of our internal control over financial reporting. For more information, see “—We are subject to ongoing costs and risks associated with determining whether our existing disclosure controls and procedures and internal controls over financial reporting systems are effective, and if we fail to achieve and maintain adequate controls it could have a material adverse effect on our stated results of operations and harm our reputation.” Our management and other personnel have devoted and will need to continue to devote a substantial amount of time to these compliance initiatives. Moreover, we expect these rules and regulations to continue to increase substantially our legal and financial compliance costs, and to make certain activities more time-consuming and costly, which will increase our operating expenses. These rules and regulations applicable to public companies may make and have made it more difficult and more expensive for us to obtain director and officer liability insurance, and we will likely incur additional costs to maintain sufficient insurance coverage as a public company going forward. We are subject to ongoing costs and risks associated with determining whether our existing disclosure controls and procedures and internal controls over financial reporting systems are effective, and if we fail to achieve and maintain adequate internal controls it could have a material adverse effect on our stated results of operations and harm our reputation. We are required to disclose whether our disclosure controls and procedures are effective on an annual basis. These are controls and procedures designed to ensure that information required to be disclosed in our SEC reports is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms, and is communicated to our management, including our chief executive officer ("CEO") and chief financial officer ("CFO"), as appropriate, to allow timely decisions regarding the required disclosure. Additionally, we are required to comply with the internal control, evaluation and certification requirements of Section 404 of the Sarbanes-Oxley Act and the Public Company Accounting Oversight Board. We are also required to provide a management report on the effectiveness of our internal control over financial reporting. The process of determining whether our existing disclosure controls and procedures are effective, and whether internal controls over financial reporting systems are compliant with Section 404 and whether there are any material weaknesses or significant deficiencies in our existing internal controls, has required and will continue to require the investment of substantial time and resources, including by our CEO and other members of our senior management. Such management time and resources, as well as our auditor fees, have increased in connection with this annual report due to the need to obtain the auditor attestation, and we expect them to continue to be significant in future years. Additionally, any remedial actions required could divert internal resources and take a significant amount of time and effort to complete and could result in us incurring additional costs that we did not anticipate, including the hiring of outside consultants. We could experience higher than anticipated operating expenses and higher independent auditor fees during and after the implementation of these changes. 33 Table of Contents Any failure of our disclosure controls and procedures or internal controls over financial reporting could have a material adverse effect on our stated results of operations and harm our reputation. If we are unable to implement any of the required changes to our disclosure controls and procedures or internal control over financial reporting effectively or efficiently or are required to do so earlier than anticipated, it could adversely affect our operations, financial reporting and/or results of operations and could result in an adverse opinion on internal controls from our management and, our independent auditors. Further, if our internal control over financial reporting is not effective, the reliability of our financial statements may be questioned, our reputation may be harmed, we may become subject to criminal or civil investigations or penalties, and our share price and its trading liquidity may suffer. Under Argentine corporate law, shareholder rights and obligations may be fewer or less well defined than in other jurisdictions. Our corporate affairs are governed by our by-laws and by the Argentine corporate law, as amended, which differ from the legal principles that would apply if we were incorporated in a jurisdiction in the United States (such as Delaware or New York), or in other jurisdictions outside Argentina. Thus, your rights or the rights of holders of our ordinary shares or ADSs under the Argentine corporate law to protect your or their interests relative to actions by our board of directors may be fewer and less well defined under Argentine corporate law than under the laws of those other jurisdictions. Although insider trading and price manipulation are illegal under Argentine law, the Argentine securities markets are not as highly regulated or supervised as the U.S. securities markets or markets in some other jurisdictions. In addition, rules and policies against self-dealing and regarding the preservation of shareholder interests may be less well defined and enforced in Argentina than in the United States, or other jurisdictions outside Argentina, putting holders of our ordinary shares and the ADSs at a potential disadvantage. The protections afforded to minority shareholders in Argentina are different from and more limited than those in the United States and may be more difficult to enforce. Under Argentine law, the protections afforded to minority shareholders are different from, and much more limited than, those in the United States. For example, the legal framework with respect to shareholder disputes, such as derivative lawsuits and class actions, is less developed under Argentine law than under U.S. law as a result of Argentina’s short history with these types of claims and few successful cases. In addition, there are different procedural requirements for bringing these types of shareholder lawsuits. As a result, it may be more difficult for our minority shareholders to enforce their rights against us or our directors or controlling shareholder than it would be for shareholders of a U.S. company. Investors may not be able to effect service of process within the United States limiting their recovery of any foreign judgment. We are a publicly held corporation (Sociedad anónima) organized under the laws of Argentina. Most of our directors and our executive officers, and a significant part of our assets are located in Argentina. As a result, it may not be possible for investors to effect service of process within the United States upon us or such persons or to enforce against us or them in United States courts judgments obtained in such courts predicated upon the civil liability provisions of the United States federal securities laws. There is doubt whether the Argentine courts will enforce, to the same extent and in as timely a manner as a U.S. or foreign court, an action predicated solely upon the civil liability provisions of the United States federal securities laws or other foreign regulations brought against such persons or against us. In addition, the enforceability in Argentine courts of judgments of U.S. or non-Argentine courts with respect to matters arising under U.S. federal securities laws or other non-Argentine regulations will be subject to compliance with certain requirements under Argentine law, including the condition that any such judgment does not violate Argentine public policy (orden público). Our shareholders may be subject to liability for certain votes of their securities. Our shareholders are not liable for our obligations. Instead, shareholders are generally liable only for the purchase price of the shares they subscribe. However, shareholders who have a conflict of interest with us and who do not abstain from voting may be held liable for damages to us, but only if the transaction would not have been approved without such shareholders’ votes. Furthermore, shareholders who willfully or negligently vote in favor of a resolution that is subsequently declared void by a court as contrary to Argentine General Companies Law or our bylaws may be held jointly and severally liable for damages to us or to other third parties, including other shareholders. As a result, we cannot assure you that some shareholders may not be held liable for damages or other expenses under the Argentine General Companies Law. 34 Table of Contents

A.History and Development of the Company Loma Negra is a corporation organized as a Compañía Industrial Argentina Sociedad Anónima under the laws of Argentina. Our principal executive offices are located at Boulevard Cecilia Grierson 355, 4th Floor, Zip Code C1107CPG – Ciudad Autónoma de Buenos Aires, Argentina and the telephone number of the office is 54-11-4319-3048. We file reports, including annual reports on Form 20-F, and other information with the SEC pursuant to the rules and regulations of the SEC that apply to foreign private issuers. The SEC maintains an internet site that contains reports, proxy and information statements, and other information regarding issuers that file electronically with the SEC. Any filings we make electronically with the SEC are available to the public at the SEC’s web site at http://www.sec.gov. Our website is http://www.lomanegra.com. The contents of our website and other websites referred to herein are not part of this annual report. We were incorporated on May 10, 1926 and registered in the regulatory agency on August 5, 1926. Our date of expiration is July 3, 2116 and, pursuant to section 4 of our bylaws, our corporate purpose includes engaging in commercial, industrial, real estate and financial activities. We are also authorized to carry out business in the mining and construction industries, and to operate transportation and public services. In 1998, we acquired the concrete operations of several producers in the greater Buenos Aires area and in the city of Rosario. These companies were merged into Loma Negra in 2010. We operate our concrete business under the Lomax brand, and we are the leading concrete company in the greater Buenos Aires area and Rosario, being specialists in large construction projects as this segment includes a broad product line of specialty concretes. In the early 2000s, we finished the construction of L’Amalí, located approximately five kilometers from our Olavarría plant, and LomaSer, located approximately 50 kilometers from the city of Buenos Aires. These two plants are connected through the Ferrosur Roca railway, being a complement of each other, aiming to better serve the greater Buenos Aires and the city of Buenos Aires area, Argentina’s most important cement consumption market. In 2005, we became part of the InterCement Group. Since then, we have invested in several projects, which have allowed us to increase production and be more efficient and competitive in a demanding market. In order to diversify our energy matrix, we invested in alternative fuels (petroleum coal-petcoke), which makes it possible to keep our kilns running throughout the year substituting, if necessary, natural gas. In 2009, we acquired La Preferida de Olavarría S.A., or La Preferida de Olavarría, a quarry of stone crushing, thereby allowing us to strengthen our vertical integration. In 2015, this company was merged into Loma Negra. In 2006, the Loma Negra Foundation was created with a vision of community development and toward the self-sustainability of projects through partnerships with several local actors or other public or private institutions. The Loma Negra Foundation primarily invests in projects related to education, capacity-building, entry of young people into the labor market and inclusive productive business. In 2012, we acquired 35% of Yguazú Cementos’, a Paraguayan cement company, outstanding shares from Votorantim Cimentos. Additionally, in 2016, we acquired an additional 16% of the company’s outstanding shares from InterCement Brasil, which led us to achieve the control of Yguazú Cementos, with 51% of ownership in the company. However, on August 21, 2020, we decided to sell our total stake in Yguazú Cementos, an operation with high standards of production and profitability. The sale was made to the local shareholder of Yguazú Cementos. We believe the economic result obtained by this operation was very beneficial for us and is in line with the goal of maximizing value for our shareholders. The sale price was US$107 million, and we used the proceeds to repay existing debt and distribute extraordinary dividends. On October 31, 2017, we completed our initial public offering and on November 1, 2017, our ADSs representing ordinary shares began to trade on the NYSE and our ordinary shares began to trade on BYMA. On December 2021, we inaugurated the second line of our L’Amalí plant, located in the city of Olavarría, in the province of Buenos Aires. This second line allowed us to increase significantly our production capacity, making our plant one of the largest in South America. The incorporation of the new line was a technological update to our plant and increased our productivity. The new line also adopted sustainability policies that comply with international environmental 35 Table of Contents guidelines in terms of environmental care. The new line has high efficiency features, low thermal and electrical consumption and water reuse systems. It incorporates a new clinker kiln that is prepared for the use of alternative fuels made from co-processed waste that replace fossil fuels. In the context of the L’Amalí expansion, and considering market demands, we decided to repurpose the Barker and San Juan plants. We transformed these plants’ full cement lines into grinding and distribution centers. In 2021, considering the facts above-mentioned, we determined to close the Sierras Bayas Plant. Our most recent material investment is to adjust our cement bags to the 25-kilogram format pursuant to Resolution 54/2018 of the Secretary of Commerce. In line with this initiative, we carried out an investment of approximately US$ 70 million in industrial infrastructure, aimed at adapting and upgrading our production processes. The project included the modernization of seven industrial plants. This milestone represents a significant shift in the Argentine construction industry, which has traditionally relied on 50-kilogram bags, and marks a transition toward safer operating conditions for construction workers. B.Business Overview We produce and distribute cement, masonry cement, aggregates, concrete and lime, which are products primarily used in private and public construction. We work with wholesale distributors, concrete producers and industrial customers, among others. We are a vertically-integrated cement and concrete company, with nationwide operations, supported by vast limestone reserves, strategically located plants, top-of-mind brands and established distribution channels. As of December 31, 2025, we held a market share of 43.6% in terms of sales volume in Argentina according to our management estimates. Over our 99-year history we have built Argentina’s sole nationwide vertically integrated cement and concrete business, supported by top-of-mind brands and captive distribution channels. As of December 31, 2025, our annual installed clinker and cement production capacities amounted to 7.3 million tons and 12.0 million tons, respectively. We hold significant, strategically located limestone reserves and we estimate that our existing quarries have sufficient reserves to support our operations for approximately 149 years, based on the cement production levels of the last five years. For the year ended December 31, 2025 and 2024, we had revenues of Ps. 848,087 million and Ps. 919,761 million, respectively, and net profit of Ps. 22,821 million and Ps. 202,094 million, respectively. For the year ended December 31, 2025 and 2024, we also had net profit margin (net profit divided by revenues and expressed as a percentage) of 2.7% and 22.0%, respectively. Our net debt (borrowings offset against cash and banks, cash-equivalent and other short term investments) as of December 31, 2025 was Ps. 266,492 million and Ps. 213,567 million for December 31, 2024. Our Products We offer our customers a broad range of high-quality cement products and a diversified product portfolio aimed at meeting all of their cement needs. Since our inception, we have developed and expanded our product range, tailoring different mixtures and product lines for a wide variety of uses and client needs. We currently produce cement (compound cement, cement with calcareous filler, pozzolana cement, as well as other specialty type cements), masonry cement, lime and concrete. In 2024 and 2025, cement accounted for 88% and 89% of our shipments, respectively. In Argentina, we sell our products under the Loma Negra trademark, which we believe is the most well-known cement brand in Argentina, and which we believe is synonymous with “cement” in the country. We believe that our brand recognition is important, given that bagged cement represents a significant part of the cement sold in Argentina. We sell our products in bulk and in bags, with bagged cement representing approximately 60% of our sales in 2024 and 57% in 2025. Cement Through our brand name Loma Negra we produce 7 different types of cement in bags and 16 types of cement in bulk. Our cement products meet all requirements and quality standards as outlined in the following Standard Specifications of the Instituto Argentino de Normalización y Certificación, or the IRAM Institute: IRAM-50000:2024, IRAM-50001:2019 and IRAM-50002:2009. These specifications were constructed based upon the European Cement Standards. The IRAM Institute is a member of the International Standard Organization, or the ISO. 36 Table of Contents Masonry Cement As part of our continued diversification of our product line, we entered the masonry cement market in 1973. Our masonry cement brand Plasticor is well-known in Argentina. In the masonry cement market we believe we are market leaders, followed by Hidralit of Cementos Avellaneda S.A., in a market that represents approximately 600 thousand tons per year. Lime We produce two different types of lime: (1) hydraulics, under the brand Cacique Max; and (2) industrial, under our brand Loma Negra Plus. These products are generally used for generic masonry, underpinning, interior and exterior plaster, interior and exterior subfloors and soil stabilization. The mixing process includes cement, sand and lime. The oldest and most traditional use of lime has been in mortar and plaster, because of its superior plasticity and workability. There are other applications of lime in construction. The dominant construction-related use of lime is soil stabilization for roads, building foundations and earthen dams. Lime is added to low quality soils to produce a usable base and sub base. Hydrated lime has long been acknowledged to be a superior anti-stripping addition for asphalt pavements. It also helps resist rutting and fracture growth at low temperatures, reduce age hardening and improve the moisture resistance and durability. Concrete and Aggregates We participate in the concrete market under our Lomax brand offering different types of concrete. We also sell granitic aggregates through our plant La Preferida in Olavarría, which comprised approximately 51.4% of the aggregates consumed by Lomax in their concrete production operations in 2025. Lomax offers a highly recognized set of solutions to our clients, including quality control, in-place facilities and logistics solutions, among other features, which can be customized to our customer’s needs. Lomax concentrates its operations on the segments in which it can assert its differential attributes: focus on quality, operational and logistic capacity and development of customized solutions. Production Process Cement Production We produce cement in a closely controlled chemical process. All our plants use the dry cement production process, incorporating state of the art technology. Below we set forth the standard phases of the cement production process, which consists of the following main stages: extraction and transportation of limestone from the quarry; grinding and homogenization to make the raw meal of consistent quality; clinkerization; cement grinding; storage in silos; and packaging, loading and distribution. 1. Mining The extraction process of the principal raw materials (limestone and clay). Naturally occurring calcareous deposits such as limestone, marl or chalk provide calcium carbonate and are extracted from quarries, often located close to the cement plant. In the pre-operational phase, the extraction process begins with mining research and probing to identify the quality and quantity of limestone. Once economic feasibility is established, we begin planning the mining work to define final digging configuration as well as the size of the fleet of vehicles and equipment needed for the operation. In the operational phase, the blocs are marked, and the holes are made by punch presses. The holes are then loaded with explosives and detonated to obtain fragmented material, which is then transported to the crushing system to reduce the granulation level. Clay extraction does not normally require explosives. 2. Transportation Limestone is loaded by large blades on dump trucks and carried to the crushing plant. 3. Primary crushing The primary crusher converts the rocks into small stones. 37 Table of Contents 4. Pre-homogenization of the limestone and clay Approximately 90% of the limestone is stored in a park, where the first homogenization of the chemical composition of the stone is achieved. At the crusher, the limestone rocks are reduced to fragments measuring approximately ten centimeters for vertical raw mills, and one inch for ball mills. This crushed limestone is then transported to the cement plant by truck or conveyor belt. Clay is also transported by truck to the plants. At the clinker plant, crushed limestone is blended by reducing the variations in chemical properties in order to obtain a homogenized mixture of limestone and clay. 5. Grinding and homogenization (“raw meal” production) The crushed pieces are then milled together to produce a powder called “raw meal”. Subsequently, the raw meal is sent to a blending/storage silo from where it is fed into the pre-heater. 6. Burning of raw meal to produce clinker (“clinkerization”) A pre-heater is a series of vertical cyclones through which the raw meal is passed. In these cyclones, thermal energy is recovered from the hot flue gases and the raw meal is preheated before it enters the kiln, so the necessary chemical reactions occur faster and more efficiently. Calcination is the decomposition of limestone to lime. Part of the reaction takes place in the “pre-calciner” and part in the kiln. Here, the chemical decomposition of limestone typically emits 65% of total emissions. The pre-calcined meal then enters the kiln. Fuel is fired directly into the kiln to reach temperatures of up to 1,450 degrees Celsius. The intense heat causes chemical and physical reactions that partially melt the meal to form a mixture of calcium silicates and other silicates, which is called “clinker”. 7. Cooling and final milling of clinker to produce cement From the kiln, the hot clinker falls onto a grate cooler where it is cooled to a temperature of approximately 100 degrees Celsius by incoming combustion air. A typical cement plant will have clinker storage between clinker production and grinding. Traditionally, ball mills have been used for grinding, although more efficient technologies like roller presses and vertical mills are used in many modern plants today. In this form, cement reacts as a binding agent that, when mixed with water, sand, stone and other aggregates, is transformed into concrete or mortar. 8. Storing in the cement silo The final product is stored in cement silos and dispatched from there to either a packing station (for bagged cement) or to a bulk silo. Most of our product is sold in paper bags, which are generated through an industry standard automatic bagging process. 9. Cement dispatch Cement is dispatched in bulk or in paper bags sacked on pallets. 38 Table of Contents The chart below illustrates the different phases of our cement production process, as numbered above: To ensure an efficient production process, our plants use monitoring and control tools, including: (1) automated controls using specialized software for the operation and monitoring of the cement production process; (2) measuring and testing equipment that offer metrological reliability; and (3) SAP system support for management of production planning and maintenance. Concrete Production Concrete is produced either in concrete plants and transported directly to construction sites as concrete in trucks or produced at the construction sites. In the concrete industry, it is crucial to have a close network of concrete plants to meet customers’ delivery needs. The concrete production process is a question of minutes with a logistic cycle of less than 2.5 hours per trip. Cement mixed with water, fine aggregates, coarse aggregates and chemical admixtures enters the hydrate phase. After a short period, a chemical reaction hardens the concrete into a permanent form of artificial stone. Compressive strength, durability, setting times, ease of placing, and workability under various weather and construction conditions characterize this building material. Lime Production 1. Mining, crushing and homogenization of the limestone The extraction process of the principal raw material: limestone. See “—Cement Production”. 2. Burning of limestone to produce quicklime (“calcination”) The limestone then enters the kiln. Fuel is fired directly into the kiln to reach temperatures of up to 1,200 degrees celsius. The intense heat causes physical reactions that partially transform limestone into quicklime. While there are multiple kiln types in use, we have a rotary kiln in our plants. A rotary kiln consists of a rotating cylinder that sits horizontal. Limestone is fed into the upper or “back end” of the kiln, while fuel and combustion air are fired into the lower or “front end” of the kiln. Limestone is heated as it moves down the kiln toward the lower end. As the preheated limestone moves through the kiln, it is “calcined” into lime to reach temperatures of up to 1,200 degrees celsius. The lime is discharged from the kiln into a cooler where it is used to preheat the combustion air. Lime can either be sold as is or crushed to make hydrated lime. 3. Cooling and storing of quicklime From the kiln, the hot lime falls onto a grate cooler where it is cooled to a temperature of approximately 200 degrees celsius by incoming combustion air. A typical lime plant will have a quicklime production and hydration and classification plant. 39 Table of Contents 4. Hydration and classification plant to produce hydrated lime Quicklime can be processed into hydrated lime by crushing the quicklime, adding water to the ground lime, and then classifying the hydrated lime to ensure it meets customer specifications before it is transported. 5. Storing in the lime silo and dispatch The final product is stored in lime silos and dispatched from there to either a packing station (for bagged hydrated lime) or to a bulk silo. Most of our product is sold in paper bags, which are generated through an industry standard automatic bagging process. Masonry Cement Production The production of masonry cement is similar to cement production, See “ —Cement Production”. However, the blending and final milling of the clinker processes vary in the production of masonry cement. 1. Blending Masonry cement consists of a mixture of clinker, gypsum and plasticizing materials (such as limestone), together with other additions introduced to enhance one or more properties of the cement, such as: setting time, workability, water retention, and durability. We prepared our additions for masonry cement at our Olavarría plant. 2. Final milling of clinker to produce masonry cement Ball mills are used for grinding. In this form, masonry cement is designed to be mixed with sand and water to produce a masonry mortar. Masonry mortar is specially formulated and manufactured for use in brick, block, and stone masonry construction. Masonry cements are also used to produce stucco. 3. Storing in the cement silos The final product is stored in cement silos and dispatched from there to either a packing station (for bagged masonry cement) or to a bulk silo. Most of our product is sold in paper bags, which are generated through an industry standard automatic bagging process. Capacity and Volumes In 2024, our production volume reached 4.8 million tons of cement, masonry and lime, and in 2025, it reached 4.9 million tons. We had a cement installed capacity of 12.0 million tons, a concrete installed capacity of 1.3 million m3, an aggregated installed capacity of 1.8 million tons annually and a lime installed capacity of 0.5 million tons annually. Annual installed capacity is based on a 365-day production per annum based on international key performance indicators, or KPIs. 40 Table of Contents The following table sets forth certain data related to our operations for the periods indicated.

At each of our plants, we review our production line, and periodically perform examinations of the raw material mix. These examinations include chemical, physical and x-ray tests. We perform similar examinations on the clinker we produce as it comes out of our kilns. In addition, we similarly test our finished products. These examinations are performed by sampling the subject material from the various points on each production line. All of our plants have received ISO 9001 certification, which reflects the quality of our products and of our operating procedures. Our quality controls comply with the ISO 9000 rules. Raw Materials The principal raw materials used in the production of cement include: (1) limestone, clay and gypsum for the production of clinker, and (2) clinker additions, including blast furnace slag, pozzolana, and paper bag, since we package a substantial portion of our cement in bags. These items, among others raw materials, collectively represented 12% in 2025, 19% in 2024 and 18% in 2023, of our total cost of sales. To further maintain our cost competitiveness, we obtain nearly all of our mineral resources from our own quarries, using, either third party services or our own mining equipment. For the year ended December 31, 2025, almost all of our limestone was sourced from our own quarries. We own and exclusively operate our limestone quarries. Mining Operations Disclosure (Mineral Reserves) The disclosures in this section titled “Mining Operations Disclosure” are provided to comply with Regulation S-K Item 1300 of the SEC, which govern disclosures by registrants engaged in mining operations. This section contains summary disclosure of all of the company’s mining operations as required by Regulation S-K Item 1303. Additionally, the company considers the La Pampita y Entorno mining operations to be individually material for purposes of application of Regulation S-K 1304, and thus has provided individual property disclosure for them as so required. Our reserves are a sum of proven and probable reserves. The terms “mineral resource,” “mineral reserves”, “proven reserves” and “probable reserves” as used in this section are defined in accordance with Regulation S-K Item 1300. “Proven reserves” are those mineral masses for which size, shape, depth and mineral content of reserves are well established, revealed by geological surveys, drilling campaigns, chemical analysis and geological modeling, to ensure exploitability and usage. All of these activities determine the quantity of minerals that matches the quality required by our production process. Our proven reserves contain suitable geological and chemical information density (drill holes) to guarantee their existence, continuity and the suitability of use. Proven reserves are constrained by a final pit configuration (effectively exploitable reserves). In addition to the foregoing, we consider reserves to be proven if they are present on land we own and if related environmental permits have been granted. “Probable reserves are mineral masses for which quantity or quality are computed from information similar to that used from proven reserves, but the sites for inspection, sampling, and measurement are farther apart. Our probable reserves contain similar suitable geological and chemical information density (drill holes) to guarantee their existence, continuity and the suitability of use than our proven reserves. The degree 42 Table of Contents of assurance, although sometimes lower than that for proven reserves, is high enough to assume continuity between points of observation. In addition to the foregoing, we consider reserves to be probable if they are not present on land we own or if related environmental permits have not been granted. Our proven and probable reserve estimates are based on estimated recoverable tons and are prepared by our engineers and geologists (at least one of whom is a “qualified person” as defined in Regulation S-K Item 1300) and then analyzed and verified by other business units within the company. For the fiscal year ended December 31, 2021, we filed as Exhibit 96.1 to the annual report on Form 20-F, a copy of the technical report summary (TRS) prepared by a "qualified person" employed at the company (the "Qualified Person") that was required by Regulation S-K Item 1302. Such TRS identifies and summarizes in all material respects the information reviewed and conclusions of such qualified person specifically to the La Pampita y Entorno individual property disclosures in this section as of the dates stated in such technical report summary. For the fiscal year ended December 31, 2025, the Qualified Person after careful review determined that there have been no material changes to our reserves at the La Pampita y Entorno quarry that would necessitate an update to the TRS filed for the fiscal year ended December 31, 2021. Therefore, we have not engaged in the preparation of a new TRS for the current reporting period. The company's engineering and geological teams, along with our corporate oversight functions, ensure ongoing accuracy and relevance of our mineral reserve data. We will continue to monitor and will disclose any material changes to our reserves in accordance with SEC requirements and our commitment to transparency and shareholder communication. In line with Regulation S-K 1300, we make no determination in this section regarding the existence of mineral resources for any of our other mining properties, as it is not material to our business. Summary Mining Operations Disclosure Overview of Mining Properties and Operations Our cement operations are supplied by limestone reserves that are located within close proximity to our production facilities. We own and operate four open-pit quarries from which limestone can be extracted efficiently due to the proximity of the limestone deposits to the surface and the quality of the limestone in the mines that meets the process requirements. We have total limestone reserves of approximately 1,072 million tons, which should be sufficient to supply us with approximately 149 years of cement production at our last five years rate of consumption. Each of our plants possesses and is responsible for several active and inactive mining licenses. Active mining licenses are those for which we hold all necessary permits and rights to actively exploit the mineral resources. Each of our plants also holds inactive mining licenses on areas for which we do not have the operational license, since their exploitation is not currently necessary. Our mining capital expenditures are focused on developing new quarries and sustaining investments, and are used mainly for mining equipment, crushing systems, safety equipment and environmental compliance. The below table includes a complete list of our mining operations, including relevant information for each quarry. As noted below, all of our mining operations are in the production stage. 43 Table of Contents List of our Mining Operations by Region Name of mining operation Location of the mining operation Type and amount of ownership interests Operator Surface Stage of the mining operation Permits Key condition of permit Type of mine / material Beneficiation plant and other installations Aggregate Production 2023 Aggregate Production 2024 Aggregate Production 2025 (Has) (in thousands of tons) Doña Amalia Catamarca 100 Loma Negra 298 Production Yes EIA (1) and others Open Pit / Limestone Mining facilities 1,621.00 1,175.10 1,251.60 Piedras Blancas (2) San Juan 100 Loma Negra 117 Closed Yes EIA (1) and others Open Pit / Limestone Mining facilities 0.1 0.0 0.0 El Salitral Zapala 100 Loma Negra 2,995 Production Yes EIA (1) and others Open Pit / Limestone Mining facilities 467.2 383.7 397.4 Barker Barker 100 Loma Negra 269 Production Yes EIA (1) and others Open Pit / Limestone Mining facilities 314.4 288.8 306.7 La Pampita y Entorno Olavarría 100 Loma Negra 1,850 Production Yes EIA (1) and others Open Pit / Limestone Mining facilities 5,632.00 3,942.80 4,178.20 La Preferida Buenos Aires 100 Loma Negra 94 Production Yes EIA (1) and others Open Pit / Granite Mining facilities 1,459.80 1,133.90 1,180.00 (1) Environmental Impact Study (EIA). Permits or licenses have been obtained, are being renewed or are being processed in accordance with current regulations. (2) As to the date of this annual report, Piedras Blancas Quarry is closed and no further exploitation is expected. The aggregate production of all limestone mining operations for each of the years ended December 31, 2025, 2024 and 2023 was 6,133.9 thousand tons, 5,790.4 thousand tons and 8,034.7 thousand tons, respectively, and the production of our granite operation for each of the years ended December 31, 2025, 2024 and 2023 was 1,180.0 thousand tons, 1,133.9 thousand tons and 1,459.8 thousand tons, respectively. The following map of Argentina shows the location of our total material and non-material mining operations. Our mining operations are located in Catamarca, San Juan, Zapala, and the central Buenos Aires region. For more information on all of our facilities, see “—Property, Plant and Equipment.” 44 Table of Contents General Map of our Mining Operations Overview of Mineral Reserves The below table summarize the mineral reserves of all of our mining concession. We do not classify our reserves by average grade. Drilling or sample density information is not the key criteria we use to distinguish proven from probable reserves. Nevertheless, to analyze the drill hole data from our quarries we assume the following distance ranges between drill holes: for active quarries, between 60 and 150 meters, and for inactive quarries, between 150 and 300 meters. The density between drill holes (samples) used in the reserves estimation process is a function of the geological complexity of the deposits and the chemical heterogeneity of the materials used in the process; therefore, we do not have a single, fixed criteria for all of our mineral reserves. We also do not use the price or cost of raw materials used in the cement production process as a variable in our reserves’ evaluation process because there is no global commodity market value for these raw materials, which prices depend on the cement local market value. We distinguish recoverable limestone from waste by evaluating whether the limestone rocks are adequate to be used in a raw mill, which is a powder composed of a clay and limestone mixture, and other minerals. In order to meet raw mill specifications, we generally use limestone with at least a 75% concentration of calcium carbonate (CaCO3). Although there is no specific cutoff grade for aggregates, we distinguish recoverable aggregates from waste by segregating the type of rock extracted from the quarry. The most common rocks used for aggregates production are granite, basalt, limestone, sand or gravel. Depending on the type of cement product, we require approximately 1.5 tons of limestone to produce one ton of clinker. On average, we require approximately 1.2 tons of limestone to produce one ton of cement product. In addition, on average, we required approximately one ton of rock to produce one ton of aggregates product. 45 Table of Contents Summary of our Mineral Reserves as of December 31, 2025 Proven mineral reserves Probable mineral reserves Total mineral reserves Amount Grades/ Qualities Amount Grades/ Qualities Amount Grades/ Qualities (Million Tons) (% CaO) (Million Tons) (% CaO) (Million Tons) (% CaO) Limestone: Doña Amalía 47.9 44.0 56.2 44.6 104.1 44.2 Piedras Blancas(2) — — — — — — Salitral (El Salitral - Cerro Bayo -Norte) 39.7 44.1 48.4 43.7 88.0 43.8 Barker 43.3 46.4 27.0 46.1 70.2 46.2 La Pampita y Entorno(1) (Don Gabino – Los Abriles – SASII) 571.6 47.4 35.3 47.1 606.9 47.4 Cerro Soltero I — — 53.5 — 53.5 — Cerro Soltero II — — 111.6 — 111.6 — El Cerro — — 37.6 — 37.6 — Granitic aggregates: La Preferida 56.7 — 54.2 — 110.9 — * The Company used an average price of US$ 93 per tonne for the economic analysis.

Individual Properties Disclosure La Pampita y Entorno Location and History The La Pampita y Entorno quarry extends over the mining operations of La Pampita, Don Gabino, Los Abriles, and San Alfredo Sur II, which are located in the district of Olavarría, Buenos Aires province. The quarry is located 20 kilometers to the southeast of the city of Olavarría, near the town of Villa Alfredo Fortabat. The region is generally characterized by nonmetal mining activity, including cement as well as aggregates and ceramics. The mining operations are carried out on land owned by Loma Negra since 1980. Exploration activity began that same year and has since been conducted discontinuously to date. Exploitation of the La Pampita mining property began in 1999. The San Alfredo Sur II, Los Abriles and Don Gabino mining properties are currently inactive and do not register any mining activities (i.e., they are entirely exploratory projects). In 2025, we did not conduct any exploration activity at the La Pampita y Entorno quarry. Our L’Amalí and Olavarría cement plant and La Pampita y Entorno mining operations are shown in the maps below. 46 Table of Contents L’Amalí and Olavarría Cement Plant Right Image — Lower right margin: Latitude: 37° 3'12.12"S, Longitude: 60°14'58.06"W.

Facilities for electric power, water supply, fuels, accesses, and roads have been installed. 47 Table of Contents La Pampita y Entorno has two primary ThyssenKrupp crushers. One sends limestone to L'Amalí plant through conveyor belts for further storage in two preheaters. The other primary crusher sends material either to the lime factory or to the secondary crusher. In the quarry, electrical energy is supplied through a 33 Kv line coming from the L’Amalí plant, and the plant is externally fed by a 132 KV line. There are seven electrical substations in the quarry. The fuel used for operational purposes is supplied to the contractor by a subcontractor. The water extracted from the quarry is used for irrigation, dust suppression sprinkler systems in crushers and belts, quarry services (buildings and restrooms) and for 100% of the water supply to the L’Amalí plant. Loma Negra’s personnel conducts its operations at La Pampita quarry with its own staff and contractors, including 18 employees and 114 outsourced staff of the contractor company. The majority of the La Pampita y Entorno quarry’s personnel comes from the town of Olavarría, adjacent to the quarry. There are also personnel from other regions of Argentina. Personnel are transported from the town of Olavarría to the quarry in buses and pickup trucks. Mining Concession Ownership and Area The mining producer registration (RPM) was granted by Resolution EX-2025 - 11821113 – GDEBA - DPGMMPCEITGP of the Undersecretary of Mining of Buenos Aires Province. The procedure to obtain a mining concession is established in Argentina’s Mining Code (as described below). We have the surface rights of the operation area in the La Pampita y Entorno quarry. Royalties The main statute that governs mining in Argentina is the Mining Code, which was enacted nationwide by Law No. 1,919 of 1886, as amended. We pay the mining canon for each concession on a bi-annual basis. Payment is equivalent to US$0.8 per hectare. The payment is made through regular banking channels. In the event that mining royalties are not declared or paid, penalties for infractions and default interest for non-compliance are incurred. However, failure to pay these fines will not result in the loss of the mining concession. We also pay a quarry exploitation fee. Municipalities establish certain taxes that may have incidence on mining developments. Each jurisdiction in which mining activities are developed has its legislation. For example, municipalities may charge a quarry exploitation quota equivalent to the amount of limestone contained in the cement dispatched or sold from the factory at a rate determined by each municipality. The rate is determined at a fixed amount, which is updated on a monthly basis. This amount represented 1.68% of sales in 2025 of cement, masonry cement and lime. Set forth below is additional information relevant to this property. Mining Activities The mining method is open pit mining, which consists of mining in a series of benches with pit expansion possible both vertically and laterally. The quarry generally proceeds top-down with a height of 10 meters. The materials are then loaded and transported to the primary crusher or waste dump by dump trucks. 48 Table of Contents The diagram below sets forth a block diagram of the mining process of the La Pampita y Entorno quarry. Diagram of Mining Process of the La Pampita y Entorno Quarry Cement Plants Our L’Amalí and Olavarría plants have been in operation for 24 and 99 years, respectively, and both use the limestone extracted from the La Pampita quarry in the manufacture of cement and lime. Our L’Amalí and Olavarría plants are located in Olavarría area. These plants are located two and five kilometers, respectively, from the La Pampita y Entorno quarry and receive raw materials from the La Pampita y Entorno quarry. Our plants produce various products for the construction industry, the main product being cement. Different types of cement are produced depending on their applications, using limestone, iron ore and clays as raw materials. Our Olavarría plant also produces lime as a product, using limestone as a raw material. The below figure shows the flow of cement production at the L'Amalí and Olavarría plants. L'Amalí and Olavarría plants process block diagram The below figure shows the flow of lime production at the Olavarría plant. 49 Table of Contents Olavarría plant process block diagram for lime production We believe that the equipment in operation at our L’Amalí and Olavarría plants is in optimal condition to avoid any interruption in cement and lime production. Maintenance and optimization of the equipment is carried out periodically and is supervised by our personnel. The equipment is in good condition and operational. Our L’Amalí and Olavarría plants have facilities such as maintenance workshops, warehouses, laboratories, administrative offices, and cement and lime production lines that support production. La Pampita y Entorno Quarry The La Pampita y Entorno quarry has been operating for 25 years. The material extracted from the quarry is exclusively used to supply our plants. The amount of limestone to be mined is planned annually as part of our overall mining plan. We believe that the equipment in operation at the La Pampita y Entorno quarry is in optimal condition to maintain continuity of operations. Maintenance and optimization of the equipment is carried out periodically and is supervised by the operator of the quarry. The equipment is in good condition and operational. Facilities The La Pampita y Entorno quarry has facilities such as offices, an electrical substation, a maintenance shop, a lubricant warehouse, a gas station, an oil tank, a guardhouse, a limestone field, a dining room, a laboratory, a truck scale, an ore belt, a loading tunnel, a meteorological station, a safety trench and a septic tank. The book value of L’Amalí and Olavarría cement plants and the La Pampita y Entorno quarry, taking into account all of the above factors, amounts to Ps. 1,001,186 million as of December 31, 2025. Property Encumbrances We do not make any payments with respect to any significant encumbrances for the L’Amalí and Olavarría plants, and the La Pampita y Entorno property. The La Pampita y Entorno mining operations currently have no outstanding payments with respect to infractions and penalties. Geology The La Pampita y Entorno quarry is located in the Tandilia System, a mountain belt which is geomorphologically composed of three main groups of small hill ranges surrounded by plains. The basement of the Tandilia System is made up of granitic complexes and sedimentary rocks of various ages. Calcareous formations are useful materials for the conformation of the raw material used in the cement industry. The contributions of CaCO3 from the calcareous levels allow a mining process suitable for the industry. The figure below shows the stratigraphic column of the area of the La Pampita y Entorno quarry, as well as a geological model of the quarry. 50 Table of Contents Geological Model of La Pampita y Entorno Quarry Reserves The table below sets forth the categories and quality of the mineral reserves of the La Pampita y Entorno operations. Summary of Mineral Reserves as of December 31, 2025 Amount Grades/ qualities Grades/ qualities Grades/ qualities Grades/ qualities Cut-off grades (Million Tons) (% SiO) (% Fe2O3) (% Al2O3) (% CaO) STC Proven mineral reserves 571.6 11.3 1.6 0.9 47.4 139.1 Probable mineral reserves 35.3 11.7 1.7 0.9 47.1 133.5 Total mineral reserves 606.9 11.3 1.6 0.9 47.4 138.8 Note: All reserves are estimated as quantities at cement plant. 51 Table of Contents For evaluation purposes, information from exploration activities from previous years has been used and is the database for the reserves model. The reserve estimation considered the quality restrictions of limestone received in L'Amalí and Olavarría cement plants, accessibility to the reserves, economic factors and modifying factors. A life of mine of 120 years has been calculated for the quarry, based on the exploitation of the last five years. Considering the maximum capacity of the plants supplied by the quarry, the life of mine would be 75 years. The following table includes a reconciliation of reserves at the end of the last two fiscal years. Reserves for the Last Two Fiscal Years Expressed in Millions of Tons* Reserves as of December 31, 2024 Reserves as of December 31, 2025 Discrepancy (Million Tons) Proven reserves 575.8 571.6 4.2 (1) Probable reserves 35.3 35.3 0 * The per-ton price assumed for the Mineral Reserves estimation in the economic model is 93 US dollars per ton. All reserves are estimated at cement plant. The average price is 93 US dollars per ton of cement, average of a 63-year projection, at nominal values. (1) The discrepancy of 4.2 million tons (1%) in the proven reserves corresponds to the lime consumption for the 2025 period. Development of the Property Activities Not applicable. Internal Controls for Reserves Disclosures We conduct annual operational governance, checking our mineral reserves and reviewing new production volumes and geologic aspects to maintain high safety standards and sufficient volume to guarantee our production without overburdening our activities. We have implemented controls and procedures designed for quality assurance and quality control on the company’s production activities and associated information for the estimation of mineral resources and reserves. The quality assurance and quality control measures are applied to quarry production and cement plant processing activities. We apply industry standards to evaluate the reliability of laboratory results that analyze exploration samples used in calculating mineral reserve estimates, which are then analyzed and verified annually by other business units within the company. Internal personnel also verify the data resulting from analysis prior to using it in their work. Additionally, we have implemented internal controls designed to ensure its mineral resources and reserves estimates are compliant with Regulation S-K Item 1300 requirements, including the preparation of reserve estimates by “qualified persons” and others on the matter in the different locations where we operate. Energy Sources We maximize the efficiency and flexibility of our operations by utilizing multiple energy sources in our production processes, which can be used interchangeably depending on price levels and supply adequacy, such as thermal energy and electrical power. Additionally, since the incorporation of the second line at the L'Amalí plant in 2021, which increased our capacity, we have been able to prioritize the operation of our kilns during periods when natural gas is widely available for industrial consumption at lower prices, minimizing the impact of higher winter costs. Regarding electricity consumption, 65.4% of our cement is produced in vertical mills, which feature superior technology compared to cement ball mills and enable us to achieve very low electrical consumption values. Energy is the largest single cost component in the production of cement and accounted for 19% of our total cost of sales in 2025 and 21% and 24% in 2024 and 2023, respectively. 52 Table of Contents Thermal Energy Thermal energy is our most utilized source of energy for our operations having accounted for 11% in 2025, 13% in 2024 and 16% in 2023, of our total cost of sales. Thermal energy is comprised of natural gas, mineral coal and petcoke, co-processing, and fuel oil (See “Co-processing”). Natural gas and petcoke are the most significant of these energy sources. Thermal energy cost is strongly impacted by the volatility of the price of natural gas and the international price of oil. Since 2006, we have diversified our fuel matrix in our main plants, so that we can optimize it at all times according to the cost of each energy source. This great versatility allows us to capture a very competitive price on the market. Historically, given the shortage of natural gas in wintertime the energy matrix of our kilns migrates to solid fuels. Currently, this flexibility to operate with different thermal energy sources, allow us to benefit from potential low thermal energy prices. In addition, our capacity surplus gives us more flexibility to manage our production scheme in order to minimize the impact of winter energy costs. To ensure the supply of gas, we entered into supply contracts, for different volumes and basins, with producers (including YPF and Pluspetrol), and marketers and distributors,such as Ecogas – Distribuidora de Gas del Centro S.A., Gas Meridional, Trafigura, Gas Patagonia and Camuzzi. All these contracts have expirations between April 2026 and 2028. In 2025, the Argentine Gas market is emerging as one of the fastest growing segments in the economy as a result of LNG export projects. Although it is premature, we expect this greater supply of gas will drive gas prices downward. The cost of petcoke varies in accordance with international market prices, which are quoted in U.S. dollars and fluctuate depending upon the supply and demand for oil and other refined petroleum products. Nevertheless, the incidence of solid fuels in our costs has been decreasing, since we reached a thermal matrix where natural gas prevails as the main source of thermal energy. Electrical Power Electrical power is one of the main drivers of our cost structure and represented 8% in 2025, 8% in 2024 and 8% in 2023, of our total cost of sales. Electrical power cost is highly influenced by the policy implemented for fuels used in electrical energy generation and by the growing share of thermal power generation in the electric matrix in Argentina. Currently, Argentina's energy system remains constrained by technical operating limits, particularly in transportation and distribution, due to a lack of investment. This is mainly a consequence of past government price policies focused on residential demand subsidies, which are still in place. In 2024, price signals were introduced that will contribute to strengthening the electrical system in the medium term. In addition, in 2025, as part of the electricity reform promoted by the Federal Government, the Secretariat of Energy issued Resolution 400/2025, which approves the rules for the normalization of the Wholesale Electricity Market (MEM, as per its acronym in Spanish). The MEM’s normalization process began on November 1, 2025 and provides for a gradual transition in which prices will float freely based on supply and demand, and the National Administrator of the Electric System (Compañía Administradora del Mercado Mayorista Eléctrico), or CAMMESA, will stop intervening in operations while maintaining its role as regulator. Although this reform is intended to introduce price signals and encourage private investment in the electric power sector, it may result in increased volatility in electricity prices. In Argentina, the energy demanded that equals the level of consumption in 2005 is marketed by CAMMESA, approximately 60% of our demand. Since 2005, it was possible to contract the rest of the consumption (approximately 40%) through private contracts. Since 2018, through Law No. 27,191, we were permitted to contract renewable energy for up to 100% of our demand. We have entered into annual contracts with Pampa Energía S.A. for the supply of approximately 35% of our current electrical power requirements. Additionally, in 2025 we covered 57% of our current electrical power requirements with renewable energy sources, overachieving the percentage stipulated by the Law No. 27,191. 53 Table of Contents Pursuant to the Law No. 27,191, consumers with a demand higher than 300kW are required to source a minimum level of their electrical power demand from renewable sources pursuant to the requirements set forth by the Law No. 27,191 equal to 8% by December 31, 2017, 12% by December 31, 2019, 16% by December 31, 2021, 18% by December 31, 2023 and 20% by December 31, 2025; provided that any consumption of renewable energy for higher levels as of each cut-off date cannot be reduced in the following periods. For purposes of complying with these minimum level requirements of renewable energy, the consumers have the option to enter into individual power purchase agreements (PPAs) with renewable energy generators, marketers or distributors, or to buy the energy through CAMMESA. We have also entered into contracts to enhance our use of green energy in a cost-efficient manner. In 2016, we signed a 20-year contract with Genneia S.A., in 2018, a 20-year contract with Aluar Aluminio Argentino S.A.I.C. and in 2025, a 5-year contract with Luz de Tres Picos S.A. and Generación Eléctrica Argentina Renovable I S.A. SDE PEO, which is expected to begin operating in September 2026. Through these contracts, we not only met the legal requirements but also exceeded them. In 2025, we signed additional short-term contracts that allowed us to achieve the aforementioned value. Co-processing Co-processing is the final disposal of waste (agricultural, urban and industrial waste) by its integration in the process of cement production as a secondary raw material or alternative fuel, as a source of energy. Co-processing is a technique used for permanently eliminating waste without generating environmental liabilities, harnessing the energy and/or mineral potential of the material. Co-processing uses duly prepared waste at different stages of the production process as a substitute for natural raw materials and/or fossil fuels. The replacement of fossil fuels and raw materials with waste provides us with a dual advantage: (1) it allows us to meet thermal needs and replace fuels derived from non-renewable natural resources in our production process; and (2) it presents a recognized benefit by disposing of waste that otherwise would have been deemed to be harmful and of environmental concern. This process is conducted safely, monitored and environmentally correct, with quality assurance of the cement produced. We have utilized the highest industry standards and technological advances in developing our co-processing operations to ensure safety and efficiency. In order to reinforce our commitment to sustainability, three of our plants are prepared for co-processing. The products we co-process are mainly municipal solid waste, or MSW, refuse-derived fuel, or RDF and hazardous industrial waste. At the end of 2019, we obtained the authorization to co-process the rejection of the urban waste, leading in Argentina the use of this waste stream in the co-processing. During 2020, we developed the use of new alternative fuel streams. In Buenos Aires, we are making progress with the co-processing of scrap tires, actively promoting the use of this type of waste in cement kilns. Sales, Marketing and Customers We are supported by a commercial, sales and marketing team of more than 64 people focused on attending our customers’ needs. This team includes the technical center Loma Negra, focused on quality control, research and development of new products and technical support for clients. We serve approximately 1,000 clients in Argentina through our dedicated sales teams. In the Greater Buenos Aires and the City of Buenos Aires area, our sales team is organized by customer category, namely distributors, concrete companies, industrial and construction companies, and public sector entities. Outside the Greater Buenos Aires and the City of Buenos Aires area, sales teams are organized by geographical region. We have long-term relationships with many of our customers, with approximately 65% of our customer base (representing over 68% of our total cement shipments) operating under long-standing, exclusive relationships. No single customer represents more than 6% of our total net sales, while our top 20 clients represented approximately 41% of total cement volume sold during 2025. We have also built a diversified customer base by sectors. Over the years, we have thoughtfully built a network of small- and medium-sized distributors throughout Argentina, and which we cultivate through a wide range of customer relationship programs, such as training and technical 54 Table of Contents assistance, aimed at improving loyalty and customer service quality. We believe that we have forged, over a long period of time, a strong client relationship based on prioritizing service and product quality. In 2025, 61% of our total cement sales were made directly to our wholesale distributors, 27% to concrete producers, 8% to industrial customers and 5% to construction companies and others. As a consequence of the activities in which we engage, our transactions do not have a significant cyclical or seasonal character. Nevertheless, during the second half of the year, historically the volume of sales in Argentina has shown a slight increase. Since our inception, we have developed and expanded our product range, tailoring different mixtures and product lines for a wide variety of uses and client needs. We provide our clients with customized construction solutions with superior quality, proven reliability and uniform performance. We believe that, by educating retailers and end-consumers of these attributes of our products, we have been successful in building demand and realizing higher margins for our differentiated product offering. Client Loyalty Throughout the years we have implemented a wide range of relationship programs focused on improving customer loyalty. Our average client is a medium-sized family-owned company mainly focused on the commercialization of cement, masonry and lime. We offer our customers technical support on a range of areas, including shops decoration, and even issues related to their business continuity. Technical Assistance We offer technical and post-sales support to customers, focusing on enhancing each customer’s capacity. In order to provide this service, we have several technical advisers who are available for different customer segments, technical visits, workshops, seminars and in site demonstrations. Marketing Efforts We are expanding the scope of our brand image strengthening campaign, adding more points of sale and improving the image of the distribution centers of our clients and consolidating the participation of our brand in the main soccer matches of the Argentine Championship, reinforcing our brand as a synonym of cement in Argentina. Distribution We have a distribution system aimed at providing the broadest product range in Argentina’s most important cement markets, particularly in the Greater Buenos Aires and the City of Buenos Aires area. Our strategy has been to base our sales and marketing efforts on our brand name recognition, broad product portfolio, customer service, efficient and timely delivery and technical support We divide our distribution platform into six regions: Buenos Aires, Central, Northwestern, Northeastern, Patagonia and Cuyo. Each of these regions is served by our production facilities. LomaSer, our mixing, distribution and logistics facility is the center of our Buenos Aires’ distribution complex, or the Buenos Aires Complex. Our Buenos Aires Complex serves the main market of the Greater Buenos Aires and the City of Buenos Aires area and provides backup supply to other regions in the rest of the country. The Province of Buenos Aires is our principal market representing 43% of our total volume sold in 2025. Our cement plants generally serve the geographic regions in which they are located. Sales of Cement in Argentina The table below shows our total market sales in each of Argentina’s regions as a percentage of total volume sold in Argentina in 2024, which is the latest annualized information available at the date of this annual report: 55 Table of Contents Region Sales Cumulative Sales (in percentages %) Buenos Aires 42 42 Center 23 65 Northwest 11 76 Northeast 8 84 Cuyo 8 92 Patagonia 8 100 ________________ Source: AFCP. Since December 31, 2021, AFCP does not publish sales information per region on a monthly basis. Additionally, as of the date of this annual report, AFCP had not published sales information for the year ended December 31, 2025. LomaSer is located approximately 50 kilometers from the City of Buenos Aires. Due to its close proximity to this important market and its mixing and bagging capacity, LomaSer enables us to respond quickly to our clients’ cement needs. For example, LomaSer has the capacity to deliver bagged or bulk cement to locations in the Greater Buenos Aires and the city of Buenos Aires area designated by its customers within 24 hours from the time a customer places its order. In addition, LomaSer is linked to our other production facilities via the Ferrosur Roca freight railway and is able to mix cement on-site that it receives from our other plants (L’Amalí, Barker and Ramallo). Argentina’s Central Region is mainly served by our Buenos Aires Complex. The Northwest area of the Patagonia region is served from our Zapala plant. The San Juan plant supplies demand from Cuyo, while Catamarca serves the Northwestern region of Argentina. The Northeast region is serviced by our Catamarca plant, through our Resistencia distribution center. The Litoral area is serviced through our Buenos Aires Complex and our Paraná distribution center. In addition, we operate the Ferrosur Roca freight railway network, which extends from the northeastern region of the City of Buenos Aires to several other regions of the country. Of the total distance of 3,100 kilometers that are part of this railway concession, approximately 2,000 kilometers are currently operational. We use the Ferrosur Roca freight railway network to ship our products and raw materials, as it is connected directly to five of our plants. In addition, third parties have access to this railway network in which we charge them freight railway fees to ship their goods. Note 5 to our consolidated financial statements discloses the sales breakdown for each of the last three fiscal years. Our Subsidiaries The following chart shows our principal subsidiaries, including our direct or indirect equity ownership interest in each of them and their main business activities as of the date of this annual report: Subsidiary Equity Ownership Interest (%) Main activity Ferrosur Roca S.A.(1) 80.00 Rail freight Recycomb S.A.U 100.00 Waste recycling ________________ (1)Indirect ownership (through Cofesur S.A.U., in which we have a direct 100% equity ownership interest). Below is a brief description of our principal subsidiaries, all of them incorporated in Argentina. Ferrosur Roca S.A. Through our subsidiary, Cofesur, we indirectly control Ferrosur Roca, a company that holds a concession to operate the Ferrosur Roca freight railway network, a 3,100 kilometer railway that runs from the northeastern region of the City of Buenos Aires to several other regions of the country and that is strategic to our business as it is linked directly to five of our plants (Ramallo, Olavarría, Barker, Zapala and L’Amalí) and also our LomaSer production and distribution 56 Table of Contents center. We own the total capital of Cofesur, which in turn owns 80% of the total capital of Ferrosur Roca. As of December 31, 2025, Ferrosur Roca had 975 employees. On March 8, 2018, Ferrosur Roca duly filed before the Ministry of Transport a request for an extension of the term of validity of the concession for ten more years. The Ministry responded on March 20, 2019, informing Ferrosur Roca that the Special Commission created by Decree No. 1027/2018 would be in charge of the renegotiation of the concession agreement, and that such process will include the analysis of the concession term extension in order to enable the implementation of the open access scheme. On November 3, 2020, the Ministry of Transport issued the Resolution No. 248/2020 to remove the Lobos-Bolívar railway branch of the General Roca line in the province of Buenos Aires (from km. 98,760 to km. 330,457) from the scope of the railway concession granted to Ferrosur Roca in 1992. In accordance with Resolution No. 211/2021, published in the Official Gazette on June 28, 2021, the Ministry of Transport rejected the extension of the term of the concession requested by different companies such as Ferrosur Roca. In that sense, Ferrosur Roca’s concession was due to expire in March 2023. Later on, the CNRT approved the registration of Ferrosur Roca as “Railway Operator” in the National Register of Railway Operators (ReNOF, as per its acronym in Spanish) by the enactment of Disposition No. 122/2022, published in the Official Gazette on February 25, 2022. Notwithstanding the above, on December 28, 2022, the Argentine Ministry of Transport issued Resolution No. 960/2022, extending the term of the concession by 18 months from March 10, 2023 to September, 2024. Such term was again extended by the Ministry of Economy on October, 2024 by means of Resolution No. 991/2024 until September 10, 2025. Subsequently, through Resolution 52/2025, the Secretariat of Transportation extended the concession term until September 10, 2026, or until a new railway concession for the General Roca line is awarded, whichever occurs first. According to Decree 195/2024, the Ministry of Economy is the authority entitled to participate in negotiations and modifications of public works and services contracts on railway infrastructures Law pursuant to No. 27,132. As of February 26, 2024, the Ministry of Economy is the new authority empowered to carry discussions or proceedings regarding the execution of Resolution 211/2021. We understand that, at the end of its concession, we will continue to provide the cargo transport rail services currently provided but as a cargo operator under the terms set forth in Resolution No. 211, Law No. 27,132, and Decree No. 1027 dated November 7, 2018, or any other business scheme that may be agreed with the competent authorities. We have reassessed all accounting estimates associated with the end of the current concession. No significant impact is expected to date. We will continue monitoring the new regulations as they come into effect, as well as the progress of ongoing negotiations with the National State and will record any related effect as soon as it is possible to make an estimate. See more information related to this issue in Note 36 to the consolidated financial statements as of December 31, 2025. See risk factor “Item 3.D. Key Information—Risk Factors—The early termination of our railway concession may have a material adverse effect on our business” for further information. Recycomb S.A.U. We own 100% of the total equity capital of Recycomb, a company that was founded in 1995. Recycomb operates a blending facility to use industrial waste and transform it into alternative fuel sources. This blending facility has an annual production capacity of 106,000 tons (30,000 tons of liquid waste-derived fuel, 36,000 tons of solids waste-derived fuel and 40,000 tons of shredded solids waste-derived fuel) and has been operational since the end of 1996. As of December 31, 2025, Recycomb had 36 employees. Information Technology We believe that an appropriate information technology infrastructure is important in order to support the growth of our business. Our data collection governance and software applications allow us to accurately monitor the processes at our various facilities, ensuring consistency and enabling us to adjust quickly in the event of any variations. Furthermore, our enterprise resources planning model and technology services allows us to develop production, sourcing and pricing models based on anticipated consumer demand. 57 Table of Contents In addition, we have license agreements involving intellectual property rights with several companies, such as Microsoft, SAP, Adobe and Aveva. Insurance We maintain insurance policies against damages to third parties, with coverage and conditions comparable to those of companies engaged in similar businesses in Argentina, respectively. We maintain insurance policies with reputable insurance companies, covering property loss and business interruption risks to our plants, equipment and buildings for partial or total damages or losses. The coverage for total loss or damage is for an insured value that we have established using as a reference the replacement value of each plant’s kiln, which is the main asset subject to risk, as we consider the total destruction of any of our plants as unlikely. For partial loss or damage, we are insured for the value at risk. As of December 31, 2025, the aggregate value at risk of our plants was US$ 1,711,993,607.

Other Argentine cement producers include Cementos Avellaneda S.A., or Avellaneda, a company controlled by Cementos Molins, S.A. and Votorantim Cimentos S.A., and Petroquímica Comodoro Rivadavia S.A., or PCR. Given the high cost of transporting cement, our competitors are generally limited in competing in the regions where their production facilities are located. We are the only cement company in Argentina with production facilities located in several regions of Argentina and with nationwide reach. The chart below sets forth the estimated cement market share in Argentina during 2025 for our company, Cementos Avellaneda, Holcim Argentina and Petroquímica Comodoro Rivadavia. 59 Table of Contents Source: AFCP and Loma Negra. Each of Argentina’s main cement companies have developed market strengths in specific areas driven primarily by the location of their facilities and their geographic focus resulting from high transportation costs which limit their ability to compete effectively over long distances. We are the only Argentine cement company to have nationwide coverage, as our facilities are located throughout the country, with particular focus on Argentina’s most important market, the Province of Buenos Aires. Our cement plants generally serve the geographic regions in which they are located. Holcim Argentina S.A. has a strong market position in the provinces of Córdoba, Mendoza and Jujuy. In recent years, our main competitors executed investments to expand their production capacity. According to available public information, Holcim Argentina S.A. expanded the “Malagueño” plant, located in the province of Córdoba. In the case of Avellaneda S.A., a similar expansion in the “El Gigante” plant in the province of San Luis was completed in late 2020 and is operating. In December 2021 we inaugurated the second line of our L’Amalí plant, which allowed us to increase our capacity, adding approximately 3 million tons annually, and transforming L’Amalí into one of the largest cement plants in South America. Concrete We participate in the concrete market under our Lomax brand. We have operations in the two main concrete markets of Argentina: (1) the City of Buenos Aires and the Greater Buenos Aires area; and (2) the city of Rosario. The Olavarría region is the main supplier of granitic aggregates consumption for the Greater Buenos Aires and the City of Buenos Aires area. We also lead this dynamic and high potential growth market through a group of selected medium- and large-sized concrete companies that have been exclusive and loyal clients of Loma Negra for many years. Legal and Regulatory Matters Environmental Regulations We develop our business in a responsible and sustainable manner, with a commitment to continuous improvement of environmental performance, minimizing the environmental impacts of our operations and providing the maximum value for society. From the point of view of compliance, this vision includes respect for environmental legislation and good relations with our stakeholders. Regarding legal requirements, we have a system for identifying, updating and evaluating environmental requirements, which is managed through an online system in all our plants and business units. In addition, we have a registration and monitoring system for environmental inspections, notifications and presentations, where the requirements of the enforcement authorities in environmental matters are managed, including possible fines and sanctions, and where the presentations made by the company are also recorded, accrediting due compliance. In 2025, no significant monetary or non-monetary fines or sanctions were recorded for non-compliance with environmental laws or regulations. We define significant breaches as those that result in fines exceeding the amount of USD 1,000,000. Considering that emissions are one of the significant impacts of our activity, it is important to note that we implement Annual Environmental Monitoring Plans (PAM-A) and we hire environmental analysis and monitoring laboratories authorized by the environmental agencies in each jurisdiction, complying with all current regulations governing emissions and air quality to ensure the protection of the atmosphere and the environment. Mining Regulations We extract limestone from quarries that we own, and quarries owned by third parties. The main statute that governs mining in Argentina is the Argentine Mining Code, which was enacted by Law No. 1,919 of 1886, as amended. The Argentine Mining Code establishes that the ownership of mineral substances existing in quarries, including limestone, is exclusively vested in the owner of the land where they are located and that provincial laws will regulate the operation of quarries. The owner may mine the quarries existing in its land or leave them inactive. However, the federal, provincial or 60 Table of Contents municipal government where the quarry is located may declare that the exploitation of the mines is of public interest and expropriate the land where the quarries are located. Pursuant to the Argentine Mining Code, as amended by Law No. 24,585, which regulates environmental aspects of the mining activity, parties involved in certain mining activities are required to file, prior to the commencement of mining activities on a tract of land, an environmental impact evaluation report with the relevant regulatory agency for its approval. If approved, the relevant regulatory agency issues an environmental impact declaration, which must be renewed every two years. C.Organizational Structure The following organizational chart sets forth our simplified corporate structure as of the date of this annual report: ________________ (1)Loma Negra has an indirect ownership in Ferrosur Roca S.A. through Cofesur SAU, in which we have a direct 100% equity ownership interest. Cofesur SAU has a direct 80% equity ownership interest in Ferrosur Roca S.A. D.Property, Plant and Equipment Our Production Facilities As of December 31, 2025, we owned seven cement manufacturing plants in Argentina: Barker, Catamarca, L’Amalí / LomaSer, Olavarría, Ramallo, San Juan, and Zapala, eleven concrete plants operating under the Lomax brand and one granitic aggregates plant. 61 Table of Contents The following table sets forth information regarding our production facilities, as of December 31, 2025: Production Facility Type of Plant Location Commissioning Year Argentina: North-east: Resistencia Warehouse Resistencia 2013 Center-east: Barker Cement Benito Juárez 1956 L’Amalí Cement Olavarría 2001/2021 LomaSer Blending/Distribution Cañuelas 2000 Olavarría Cement Olavarría 1929 Ramallo Grinding Mill Ramallo 1998 Paraná Warehouse Paraná Patagonia: Zapala Cement Zapala 1970 Cuyo: San Juan Cement San Juan 1963 Mendoza Warehouse Palmira 2020 North-west: Catamarca Cement El Alto 1980 Salta Warehouse Salta 2020 Concrete plants under the Lomax brand: Don Torcuato Concrete Greater Buenos Aires area 1998 Sola Concrete City of Buenos Aires 1998 Llavallol Concrete Greater Buenos Aires area 1998 Uriburu Concrete Rosario 2010 Darsena F 1 Concrete City of Buenos Aires 2017 Darsena F 2 Concrete City of Buenos Aires 2018 Vicente Casares Concrete Greater Buenos Aires area 2018 Escobar Concrete Greater Buenos Aires area 2020 Fatima Concrete Greater Buenos Aires area 2023 Punta Alta - Movil Plant Concrete Buenos Aires Province 2024 MSU Rufino - Movil Plant Concrete Santa Fe Province 2024 Aggregates plant: La Preferida Aggregates Olavarría 2004 62 Table of Contents The map below presents the location of our facilities: Barker The Barker plant began operations in 1956 and is located in the City of Benito Juárez, Province of Buenos Aires. The Barker plant currently has total annual cement and filler production capacity of approximately 1.3 million, using one dry-process kiln. The Barker plant has capacity to produce cement and also produces filler, which is used for cement mixing by LomaSer. In the context of the L’Amalí expansion project, and considering the actual demand, during 2019 we decided to reconvert our Barker and San Juan plants, transforming both full cement lines into grinding and distribution centers, and we have adapted our cost structure to reflect this new scenario. Catamarca The plant of Catamarca began operations in 1980 and is located in the City of El Alto, Province of Catamarca.

The map below presents the location and connections among our facilities with LomaSer in the Greater Buenos Aires area, as well as the Ferrosur Roca freight railway network, which we use to ship our products and raw materials, as it is connected directly to six of our plants. (1)Railroad segment we actively use. 64 Table of Contents LomaSer has a flexible production facility that allows production to be switched rapidly between one type of cement to another. The ability to customize the blending according to each additions’ characteristic enables us to produce superior quality cement while optimizing the maximization of additions. LomaSer operates approximately 40% of our total cement dispatches. It ships cement in bags or in bulk depending on its customers’ needs. Olavarría The Olavarría plant began operations in 1929 and it is located in the City of Olavarría, Province of Buenos Aires. The plant currently has two active dry-process kilns with a kiln production capacity of approximately 0.4 million tons of lime, and a second kiln with an installed capacity of 1.0 million tons of annual production capacity of clinker and 1.7 million tons of annual production capacity of cement. The Olavarría plant produces cement, as well as masonry cement and lime. It principally serves the Buenos Aires region. For additional information relating to our mining operations at Olavarría plant, see "Item 4.B. Business Overview—Mining Operations Disclosure (Mineral Reserves)—Individual Properties Disclosure." Ramallo The Ramallo plant was inaugurated in 1998 and it is located in the City of Ramallo, Province of Buenos Aires. Ramallo produces cement and also mills slag that is used by LomaSer. This plant has annual cement installed production capacity of 0.5 million tons. We acquire slag from Siderar S.A.I.C., Argentina’s largest steel company, which is located near this plant. The Ramallo plant serves the northern portion of the Province of Buenos Aires and the Province of Santa Fe. San Juan The San Juan plant began operations in 1963 and it is located in the City of Rivadavia, Province of San Juan. It has an annual cement production capacity of approximately 0.4 million tons and uses a dry-process kiln. In 1993, a new facility was installed in this plant to enable it to store and process coal, enabling it to operate either using natural gas or a combination of natural gas, fuel oil and coal, together with liquid alternative fuels. The San Juan plant serves the Province of San Juan and certain neighboring provinces. In the context of the L’Amalí expansion project, and considering the actual demand, during 2019, we decided to reconvert our Barker and San Juan plants, transforming both full cement lines into grinding and distribution centers, and we have adapted our cost structure to reflect this new scenario. Zapala The Zapala plant began operations in 1970 and it is located in Zapala, Province of Neuquén. This plant has a dry-process kiln, with annual installed cement production capacity of 0.4 million tons and annual installed clinker production capacity of approximately 0.2 million tons.

It mainly serves the provinces of Neuquén and Río Negro and exports approximately 2% of its cement to Southern Chile. La Preferida In 2009, we commenced operations in the aggregates market in Argentina with our acquisition of La Preferida de Olavarría, which is located in the City of Olavarría, Province of Buenos Aires. In 2018, a new crusher started to operate. This plant has annual aggregates production capacity of 1.8 million tons. 65 Table of Contents We sell granitic aggregates through La Preferida de Olavarría, which is responsible for approximately 44% of the aggregates consumed by Lomax in their concrete production operations. Investments With the completion of the second line of the L’Amalí plant in December 2021, L’Amalí has become the largest cement plant in Argentina and one of the largest in Latin America, based on annual installed cement production capacity. With the finalization of this expansion project, capital expenditures decreased significantly. Our most recent material investment is to adjust our cement bags to the 25-kilogram format pursuant to Resolution 54/2018 of the Secretary of Commerce. In line with this initiative, we carried out an investment of approximately US$ 70 million in industrial infrastructure, aimed at adapting and upgrading our production processes. The project included the modernization of seven industrial plants. This milestone represents a significant shift in the Argentine construction industry, which has traditionally relied on 50-kilogram bags, and marks a transition toward safer operating conditions for construction workers. As of the date of this annual report, we have no other material investments in development or future material investments plans.

The following discussion should be read in conjunction with our audited consolidated financial statements and the related notes included elsewhere in this annual report. This discussion contains forward-looking statements that are subject to known and unknown risks and uncertainties. Actual results and the timing of events may differ significantly from those expressed or implied in such forward-looking statements due to a number of factors, including those set forth in the section entitled “Key Information—Risk Factors” and elsewhere in this annual report. You should read the following discussion in conjunction with “Cautionary Statement with Respect to Forward-Looking Statements” and “Key Information—Risk Factors”. A.Operating Results Principal Factors Affecting Our Results of Operations Macroeconomic Conditions Our business is highly sensitive to factors such as GDP growth (globally and in Argentina, the cement industry has a strong positive correlation with GDP growth). An economic slowdown can lead to a slowdown in the construction industry and consequently decreased cement demand and production. Likewise, an expansion of GDP is expected to drive incremental cement demand, above expected GDP growth. During 2025, according to the INDEC, the Argentine economy increased 4.4%, after decreasing 1.3% and 1.9% in 2024 and 2023, respectively. 66 Table of Contents The following table presents key data of the Argentine economy for the periods indicated. As of and for the Year Ended December 31, 2025 2024 2023 GDP (billions of Ps.) 739.1 708.1 714.6 GDP growth 4.4 % (1.3) % (1.6) % GDP per capita (in thousands of U.S. dollars) 14.1 13.4 12.9 Private consumption growth 7.9 % (2.9) % 1.0 % Average Ps./U.S. dollar exchange rate(1) 1,244.3 916.3 295.2 CPI inflation 31.5 % 117.8 % 211.4 % Private sector salary growth 28.7 % 147.5 % 165.8 % Unemployment rate(2) 7.4 % 7.2 % 6.1 % ________________ Sources: BCRA, INDEC and our company. (1)The average rate is calculated by using the average of the BCRA’s reported exchange rates on a daily basis. (2)As a percentage of Argentina’s economically active population. Quarterly average. Inflation Our audited consolidated financial statements comprehensively recognize the effects of variations in the purchasing power of currency through the application of the method to restate financial statements in constant currency established by the IAS 29. As a result, our financial statements are stated in the unit of currency that was current at the end of the fiscal year that is being reported. See “Presentation of Financial and Other Information”. In accordance with IAS 29, the amounts in the financial statements that have not been stated in constant currency as of the end of the reporting period must be restated by application of a general price index. To that end and in the manner established in FACPCE´s Resolution JG No. 539/18, coefficients have been applied that are calculated on the basis of indices published by the FACPCE, resulting from combining national consumer prices published by the Instituto Nacional de Estadística y Censos (the National Statistics and Census Institute), or INDEC, starting on January 1, 2017 and, looking back, domestic wholesale prices, or IPIM prepared by INDEC or, if none is available, consumer price indices published by the General Directorate of Statistics and Censuses in the Autonomous City of Buenos Aires. The variation, in the index applied to restate our audited consolidated financial statements for the years ended as of December 31, 2025, 2024, 2023, 2022 and 2021 has been 31.5%, 117.8%, 211.4%, 94.8% and 50.9%, respectively. Foreign Currency Exchange Rate Our liabilities that are exposed to foreign currency exchange rate risk are primarily denominated in U.S. dollars. To partially offset our risk of any depreciation of the peso against the U.S. dollar, from time to time we may enter into derivative contracts. Because we borrow in U.S. dollars in international or local markets to fund our operations and investments, we are exposed to market risks from changes in foreign exchange rates and interest rates. Our foreign currency exposure gives rise to market risks associated with exchange rate movements. A significant portion of our borrowings are denominated in foreign currency. As of December 31, 2025, our consolidated foreign currency-denominated borrowings were Ps. 253,981 million, denominated in U.S. dollars. As of December 31, 2025, we did not have foreign currency derivative financial instruments. In the event that the peso were to depreciate by 25% against the U.S. dollar as compared to the peso/U.S. dollar exchange rate as of December 31, 2025, our foreign currency net liability position as of December 31, 2025 would have increased by Ps. 66,093 million. 67 Table of Contents Due to the foreign exchange crisis after the primary elections in August 2019, the Argentine Central Bank reinstated rigid restrictions and foreign exchange controls. For more information about such restrictions see “Item 10.D. Additional Information—Exchange Controls”. Considering the mentioned restrictions based on the current exchange regulations applicable in Argentina, we constantly monitor the alternatives for collecting assets and settling liabilities in foreign currency and the related impact. The gain/loss arising from the use of financial instruments to settle transactions in foreign currency is recognized when we unconditionally commit to or irreversibly executes such settlement. As of December 31, 2025, the use of financial instruments to settle the above transactions would result in an impact of approximately 1.5% as mentioned in note 32.4.1. to the consolidated financial statements as of such date. As of December 31, 2021, the official nominal exchange rate for pesos into U.S. dollars fell to Ps. 102.7500 per US$1.00, a devaluation of approximately 22.1% as compared to the official exchange rate of Ps. 84.1450 per US$1.00 as of December 31, 2020. As of December 31, 2022, the official nominal exchange rate for pesos into U.S. dollars fell to Ps. 177.1283 per US$1.00, a devaluation of approximately 72.4% as compared to the official exchange rate of Ps. 102.7500 per US$1.00 as of December 31, 2021. As of December 31, 2023, the official nominal exchange rate for pesos into U.S. dollars fell to Ps. 808.4833 per US$1.00, a devaluation of approximately 356.44% as compared to the official exchange rate of 177.1283 per US$1.00 as of December 31, 2022. As of December 31, 2024, the official nominal exchange rate for Ps. into U.S. dollars fell to Ps. 1032.50 per US$1.00, a devaluation of approximately 27.7% as compared to the official exchange rate of 808.4833 per US$1.00 as of December 31, 2023. As of December 31, 2025, the official nominal exchange rate for Ps. into U.S. dollars fell to Ps. 1459.4167 per US$1.00, a devaluation of approximately 41.3% as compared to the official exchange rate of Ps. 1,032.5000 per US$1.00 as of December 31, 2024. In the first three months of 2026, the peso appreciated by approximately 5.25% against the U.S. dollar. The following table sets forth the annual high, low, average and period-end exchange rates for the periods indicated, expressed in pesos per U.S. dollar and not adjusted for inflation. There can be no assurance that the peso will not depreciate or appreciate again in the future. The Federal Reserve Bank of New York does not report a non-buying rate for pesos.

(2)Based on daily averages. Net Capital Expenditures and Other Investments Our most recent material investment is to adjust our cement bags to the 25-kilogram format pursuant to Resolution 54/2018 of the Secretary of Commerce. In line with this initiative, we carried out an investment of approximately US$ 70 million in industrial infrastructure, aimed at adapting and upgrading our production processes. The project included the modernization of seven industrial plants. This milestone represents a significant shift in the Argentine construction industry, which has traditionally relied on 50 kilogram bags, and marks a transition toward safer operating conditions for construction workers. On a consolidated basis, our capital expenditures incurred in property, plant and equipment were Ps. 62,886 million during the year ended December 31, 2025 and Ps. 96,094 million and Ps. 103,280 million during the years ended December 31, 2024 and 2023, respectively. 68 Table of Contents Our Cost Structure The prices that we charge for our cement products are directly related to our production costs. Fluctuations in the price of our thermal energy sources and electricity impact our costs of goods sold and the prices that we charge our customers for our products. Significant increases in the price of natural gas, solid fuels or electricity and, consequently, in our production costs, could reduce our gross margins and our results of operations to the extent that we might not be able to pass a significant portion of these costs on to our customers and could result in reduced sales volumes of our products. Conversely, significant decreases in the price of natural gas, solid fuels or electricity and, consequently, in our production costs, would likely increase our gross margins and our results of operations. Our efforts on increasing the use of co-processing (use of waste as a source of a renewable energy, to replace natural mineral resources and fossil fuels such as coal, petcoke and gas) on our production process aims to decrease both our dependency on certain energy sources and reduce costs. In 2025, the percentage of co-processing used in our production process reached 4.6%. Thermal Energy. Our operating income has been affected by energy price changes. Energy prices may vary in the future, mainly due to market forces and other factors outside our control. We protect ourselves from energy price inflation risks through the diversification of our fuel sources (including solid fuels and the use of co-processing as an alternative energy source) and our ability to transfer all or part of increased costs to our customers via price increases for our products. We also seek to produce different types of cement with lower clinker content, replacing it with other components such as slag, pozzolana, and limestone, which reduce our overall energy costs. Thermal energy is our most utilized source of energy for our operations, representing 11% in the year ended December 31, 2025 and 13% and 16% in the years ended December 31, 2024 and 2023, respectively, of our total cost of sales. Thermal energy is comprised of natural gas, fuel oil, mineral coal and petcoke. Natural gas is the most significant of these energy sources. We enter into several contracts with suppliers, traders and distributors of natural gas. See “ —Supply Contracts”. The cost of petcoke varies in accordance with international market prices, which are quoted in U.S. dollars and fluctuate depending upon the supply and demand for oil and other refined petroleum products. Nevertheless, the incidence of solid fuels in our costs has been decreasing, since we reached a thermal matrix where natural gas prevails as the main source of thermal energy. Electrical power. Electrical power is one of the main drivers of our cost structure and represented 8%, 8% and 8% in the years ended December 31, 2025, 2024, and 2023, respectively, of our total cost of sales. Electrical power is one of the most expensive energy sources that we use. Given our consumption needs and the potentially high cost of electrical power, we have sought to mitigate the risks of supply interruptions and cost increases by contracting electrical power to private companies and entering into agreements to increase the use of renewable energy. Electrical power cost is highly influenced by the government policy applied to fuels used in electrical power generation and by the growing contribution of thermal power generation to the electrical power generation matrix in Argentina. In 2024 and 2025 price signals were introduced that will contribute to strengthening the electricity system and support the transition towards a competitive energy market in the medium term. Consumers with a demand higher than 300kW are required to source a minimum level of their electrical power demand from renewable sources equal to 8% by December 31, 2017, 12% by December 31, 2019, 16% by December 31, 2021, 18% by December 31, 2023 and 20% by December 31, 2025; provided that any consumption of renewable energy for higher levels as of each cut-off date cannot be reduced in the following periods. For purposes of complying with these minimum level requirements of renewable energy, the consumers have the option to enter into individual power purchase agreements with renewable energy generators, marketers or distributors, or to buy the energy through CAMMESA See “ —Supply Contracts”. In 2016, we entered into a 20-year agreement with Genneia S.A., in 2018 entered into a 20-year agreement with Aluar Aluminio Argentino S.A.I.C. and in 2025 a 5-year contract in 2025 with Luz de Tres Picos S.A. and Generación Eléctrica Argentina Renovable I S.A. SDE PEO, which will begin operating in September 2026 to enhance the use of green energy. Through these contracts and other short-term contracts that we signed in 2025, we not only complied with the legal limits but also exceeded the minimum required levels. Co-Processing. During 2025, we continued with our co-processing efforts. Co-processing is the final disposal of waste (agricultural, urban and industrial waste) through its integration in the cement production process as a secondary raw material or alternative fuel, as a source of energy. Co-processing is a technique used for permanently eliminating waste 69 Table of Contents without generating environmental liabilities, by harnessing the energy and/or mineral potential of the material. Co-processing represented 4.6% in the year ended December 31, 2025 and 4.3% and 2.2% in the years ended December 31, 2024 and 2023, respectively, of our total thermal energy consumption. For additional information related to our thermal energy, electrical power and co-processing needs and costs, see “Item 4.B Information on the Company—Business Overview—Energy Sources”. Preservation and maintenance costs. Our industry is capital intensive, and we incur in maintenance costs necessary to preserve the productivity and durability of our cement facilities. In the year ended December 31, 2025 preservation and maintenance costs represented 10% and in the years ended December 31, 2024 and 2023, represented 11% and 9%, respectively, of our total cost of sales. Freight. Our freight includes the cost of transporting raw materials to our production facilities from our quarries or the location of our suppliers. In the year ended December 31, 2025 freight represented 10% and in the years ended December 31, 2024 and 2023, freight represented 9% and 10%, respectively, of our total cost of sales. Salaries, wages and social security charges. Our salaries, wages and social security charges comprise mainly compensation, social contribution and employee benefits. In the year ended December 31, 2025 salaries, wages and social security charges represented 17% and in the years ended December 31, 2024 and 2023, salaries, wages and social security charges represented 17% and 15%, respectively, of our total cost of sales. Raw Material Availability. Our long-term success depends in part on our ability to secure raw materials in sufficient quantities, including limestone, gypsum and other materials necessary for the production of clinker and cement, which are currently available to us from quarries located close to the different industrial units. We generally obtain limestone from the mining of quarries that we own. In some cases, however, we may face the risk of the exhaustion of raw materials in some quarries, most notably limestone, which would require us to find new quarry sources further away from our production units, and result in potential materially higher raw material extraction and freight costs. In the year ended December 31, 2025 raw materials represented 12% and in the years ended December 31, 2024 and 2023, raw materials represented 19% and 18%, respectively, of our total cost of sales. Effects of Taxes on Our Income We are subject to a variety of generally applicable Argentine federal and state taxes on our operations and results. We are subject to Argentine federal Income Tax by applying a sliding scale from 25% to 35%, depending on the accumulated net income obtained during the given year. Dividends paid to Argentine individuals and foreign beneficiaries (both individuals and entities) are subject to a 7% withholding tax made by the paying entity. We are also subject to the following federal and state taxes: •Turnover Tax. The Turnover Tax is a provincial tax and the rate applicable depends on each province. Currently, the Turnover Tax represents approximately 1.45% of our net sales. •Quarry Exploitation Fee. Municipalities establish certain taxes that may have incidence on mining developments. Each jurisdiction in which mining activities are developed has its particular legislation. For example, Municipalities may charge a quarry exploitation quota equivalent to the amount of limestone contained in the cement dispatched or sold from the factory at a rate determined by each municipality. The rate is determined at a fixed amount, which is updated in a monthly basis. This amount represented 1.68% of sales in 2025 of cement, masonry cement and lime. •Tax on Bank Accounts Debits and Credits. The general rate of the tax on bank accounts debits and credits is 0.6% for each debit and each credit, while an increased rate of 1.2% applies in cases in which there has been a substitution for the use of a bank account. Taxpayers (whether at 0.6% or 1.2% rate) may compute 33% of the amounts paid under this tax as a payment on account of the income tax. Law 27,264, in force since August 2016, establishes that micro and small sized companies may apply 100% of this tax as an advance payment of income tax, medium industrial sized may apply 50% of this tax as an advance payment of income tax. Moreover, Law 27,432 establishes that the Executive Branch may increase up to 20% per year the percentage of the payments of this tax that can be computed for as payment on account of Argentine income tax. The government has not exercised this faculty since 2018 and currently it is uncertain if an increase of the computable amounts will take place in the medium term. 70 Table of Contents •Stamp Tax. Stamp tax is a local tax that is levied based on the formal execution of public or private instruments. Documents subject to stamp tax include, among others, all types of contracts, notarial deeds and promissory notes. Each province and the City of Buenos Aires have their own stamp tax legislation. Stamp tax rates vary according to the jurisdiction and agreement involved. In general, stamp tax rates vary from 0.5% to 3.5% and are applied based on the economic value of the instrument. •Personal Assets Tax. An annual net wealth tax applies on the net equity where the shareholder is a nonresident or a resident individual at a rate of 0.50%. We have the right to request reimbursement from the shareholder. The taxable base of the personal assets tax is the book value of the shares as stated in the last financial statements issued on December 31 on the relevant tax period. We are also subject to certain other non-material duties and taxes. Effect of Indebtedness Level and Interest Rates As of December 31, 2025, our total outstanding borrowings on a consolidated basis were Ps. 297,908 million. The level of our indebtedness results in financial results that are reflected in our consolidated statement of profit or loss and other comprehensive income. Financial results consist of interest expense, exchange gains (losses) on U.S. dollar and other foreign currency-denominated debt, and other items as set forth in Note 10 to our audited consolidated financial statements. During 2025, we recorded financial expenses of Ps. 57,960 million, which included Ps. 47,443 million in interest expense related to our loans and financings, and Ps. 85,133 million of exchange losses which included Ps. 91,034 million related to our loans and financings. In addition, a gain on a net monetary position of Ps. 89,083 million of out a total of Ps. 90,039 million is also related to such liabilities. The interest rates we pay on our indebtedness depend on a variety of factors, including prevailing Argentine and international interest rates, any collateral or guarantees and risk assessments of our company, our industry and the economies in Argentina and other markets in which we operate made by our potential lenders, potential purchasers of our debt securities and the rating agencies that assess our debt securities. Financial Presentation and Accounting Practices Presentation of Financial Statements We maintain our financial books and records in pesos. We have prepared our annual audited consolidated financial statements in accordance with IFRS Accounting Standards, as issued by the IASB. We have adopted all new and revised standards and interpretations issued by the IASB that are relevant to our operations and that are mandatorily effective as of December 31, 2025. The application of these amendments has had no impact on the disclosures or amounts recognized in our audited consolidated financial statements. Our audited consolidated financial statements have been prepared on a historical cost basis, which has been restated in end-of-period currency in the case of non-monetary items. Upon estimating the fair value of an asset or a liability, we take into consideration the characteristics of the asset or the liability when market participants do take these features into consideration when valuing the asset or the liability at the date of measurement. Fair value for purposes of measurement and/or disclosure in our financial statements is determined on that basis, except for the transactions consisting in share-based payments that are within the scope of IFRS 2, lease transactions within the scope of IFRS 16 and the measurements that have certain points in common with fair value but are not fair value such as net realizable value in IAS 2 or value in use in IAS 36. Besides, for financial reporting purposes, fair value measurements are categorized as level 1, 2 or 3 on the basis of the degree to which fair value measurement inputs are observable and the impact of inputs for fair value measurements overall as described below: •Level 1: quoted (unadjusted) market prices in active markets for identical assets or liabilities that the entity can access at the measurement date; •Level 2: valuation techniques for which the lowest level input that is significant to their value measurement is directly or indirectly observable; and •Level 3: valuation techniques for which the lowest level input that is significant to the fair value measurement is unobservable. 71 Table of Contents Classification into current and non-current: We present assets and liabilities in our consolidated statement of financial position classified as current and non-current. Assets are classified as current when: (i)we expect to realize the asset or intend to sell or consume it during its normal operation cycle; (ii)we maintain the asset primarily for trading purposes; (iii)we expect to realize the asset within twelve months after the reporting period; or (iv)the asset is cash or cash equivalents unless the asset is restricted and may not be exchanged or used to settle a liability for at least twelve months after the reporting period. All the other assets are classified as non-current Liabilities are classified as current when: (i)we expect to settle the liability during its normal operation cycle; (ii)we maintain the liability primarily for trading purposes; (iii)the liability must be settled within the twelve months after the reporting period; or (iv)we do not have an unconditional rights to defer settlement of the liability for at least the twelve months after the reporting period. All the other liabilities are classified as non-current. Deferred tax assets and liabilities are classified as non-current assets and liabilities in all cases. Use of estimates The preparation of consolidated financial statements requires our board of directors to make judgments, estimates and assumptions that affect the reported amounts of the revenues, expenses, assets and liabilities and the accompanying disclosures, and the disclosure of contingent liabilities. Uncertainty about these assumptions and estimates could result in outcomes that require a material adjustment to the carrying amount of assets or liabilities affected in future periods. The description of the estimates and significant accounting judgments made by our board of directors in the application of accounting policies as well as areas with a higher degree of complexity that require further judgment are disclosed in Note 4 to our audited consolidated statements. The principal accounting policies are discussed below. Principal Accounting Policies Standards and Interpretations issued but not yet effective The following is a description of the standards and interpretations that have been published but are not yet effective as of the date of issuance of our consolidated financial statements. We intend to adopt these standards, if applicable, when they become effective. Amendments to IFRS 7 and IFRS 9 In May 2024, the Board issued Amendments to the Classification and Measurement of Financial Instruments (Amendments to IFRS 9 and IFRS 7), in which the Board: –Clarifies that a financial liability is derecognized on the “settlement date,” i.e., when the related obligation is discharged, cancelled, expires or the liability otherwise qualifies for derecognition. It also introduces an 72 Table of Contents accounting policy option to derecognize financial liabilities that are settled through an electronic payment system before the settlement date if certain conditions are met. –Clarifies how to assess the contractual cash flow characteristics of financial assets that include environmental, social and governance (ESG) and other similar contingent characteristics. –Clarifies the treatment of non-recourse assets and contractually linked instruments. –Requires additional disclosures in IFRS 7 for financial assets and liabilities with contractual terms that refer to a contingent event (including those that are linked to ESG) and equity instruments classified at fair value through other comprehensive income. These amendments are effective for reporting periods beginning on or after January 1, 2026, but earlier application is permitted. No impacts are expected from the application of these amendments. •IFRS 18 Presentation and Disclosure in Financial Statements In April 2024, the IASB issued IFRS 18, which replaces IAS 1 Presentation of Financial Statements. IFRS 18 introduces new requirements for presentation within the income statement, including specified totals and subtotals. In addition, it requires entities to classify all income and expenses within the income statement into one of five categories: operating, investing, financing, income taxes, and discontinued operations. It also requires disclosure of management-defined performance measures, subtotals of income and expenses, and includes new requirements for the aggregation and disaggregation of financial information based on the identified roles of the primary financial statements and notes. In addition, limited-scope amendments have been made to IAS 7 Statement of Cash Flows, including changing the starting point for determining cash flows from operations under the indirect method from "profit or loss" to "operating profit or loss" and eliminating the optionality surrounding the classification of cash flows from dividends and interest. In addition, there are consequential amendments to several other standards. IFRS 18, and the amendments to the other standards, are effective for reporting periods beginning on or after January 1, 2027, but earlier application is permitted, which must be disclosed. IFRS 18 will be applied retrospectively. The Group is currently working to identify all the impacts that the new standard will have on the primary financial statements and notes to the financial statements. •IFRS 19 Subsidiaries without Public Accountability: Disclosures In May 2024, the IASB issued IFRS 19, which allows eligible entities to elect to apply its reduced disclosure requirements while still applying the recognition, measurement and presentation requirements in other IFRS accounting standards. To be eligible, at the end of the reporting period, an entity must be a subsidiary as defined in IFRS 10, cannot have public accountability and must have a parent (ultimate or intermediate) that prepares consolidated financial statements, available for public use, which comply with IFRS accounting standards. IFRS 19 will become effective for reporting periods beginning on or after 1 January 2027, with early application permitted. As the Group’s equity instruments are publicly traded, it is not eligible to elect to apply IFRS 19. •Amendment to IAS 21 Translation to a Hyperinflationary Presentation Currency In November 2025, the IASB issued amendments to IAS 21, concerning the translation of amounts from a functional currency that is the currency of a non-hyperinflationary economy to a presentation currency that is the currency of a hyperinflationary economy. The amendments require the translation of a non-hyperinflationary functional currency to a hyperinflationary presentation currency at the closing exchange rate. An entity whose functional and presentation currency is that of a hyperinflationary economy restates the comparative amounts of a foreign operation, whose functional currency is that of a non-hyperinflationary economy, by applying the general price index, in accordance with paragraph 34 of IAS 29, to the comparative figures of the foreign operation. Amendment to IAS 21 will become effective for reporting periods beginning on or after 1 January 2027, with early application permitted. The amendment is not expected to have a material impact on the Group’s financial statements. 73 Table of Contents Adoption of new standards and interpretation We have adopted all the improvements and new standards and interpretations issued by IASB that are relevant to our operations and that are effective for the financial year ended December 31, 2024. As from January 1, 2024, we began to apply the following standards: •Lack of exchangeability - Amendments to IAS 21 In August 2023, the IASB issued amendments to IAS 21 “The Effects of Changes in Foreign Exchange Rates”. The amendments to IAS 21 specify how an entity should assess whether a currency is exchangeable and how it should determine a spot rate when exchangeability is lacking. The amendments also require disclosures that enable users of financial statements to understand how the non-exchangeability of the currency into another currency affects, or is expected to affect, the entity's financial performance, financial position and cash flows. There were no impacts arising from the application of this modification on the Group's consolidated financial statements. Material Accounting Policies Material accounting policies are those that are important to the presentation of our financial condition and results of operations and that require our management to make difficult, subjective or complex judgments, often as a result of the need to make estimates about the effect of matters that are inherently uncertain. As the number of variables and assumptions affecting the possible future resolution of the uncertainties increases, those judgments become even more subjective and complex. For more information about our critical accounting policies, see the notes to our audited consolidated financial statements. In order to provide an understanding of how our management forms its judgments about future events, including the variables and assumptions underlying the estimates, and the sensitivity of those judgments to different circumstances, we have identified the following critical accounting policies: •revenue recognition; •leases; •foreign currency and functional currency; •borrowing costs; •taxation (income tax and personal assets tax); •property, plant and equipment; •intangible assets; •impairment of tangible and intangible assets; •inventories; •provisions, including environmental restoration and assets decommissioning obligations, and provision for lawsuits and other contingencies; •financial instruments; •financial assets; •financial liabilities and equity instruments; •short- and long-term employee benefits; •stripping and quarry exploitation costs; •Ferrosur Roca S.A. concession; and •Management’s account estimates and judgments on environmental matters. Revenue recognition We are engaged in the production and distribution of cement, masonry cement, concrete, limestone and aggregates, as well as logistics services through railway concession, and the industrial waste recycling business. The goods 74 Table of Contents to be delivered and the services to be provided arise from agreements with commercial substance (in general, they are not written) where we may identify the right of each one of the parties and the payment terms. Sale of goods Revenues from sales of goods are recognized when control over goods is transferred to the customer for an amount that reflects the consideration that we expect to be entitled to in exchange for such assets. The customer obtains control of the goods when significant risks and rewards of the products sold are transferred in accordance with the specific delivery terms agreed with the customer. Revenues from the sale of goods are measured at fair value of the consideration received or to be collected, net of commercial discounts. No financing components are considered in the transaction since credit terms vary greatly between 20 and 35 days, depending on the specific terms agreed upon, which is consistent with market practices. Some agreements with customers offer commercial discounts or volume-based discounts. If revenues cannot be reliably measured, we defer revenue recognition until the uncertainty is resolved. However, due to the fact that performance obligations relate mainly to the delivery of the acquired goods, and that both the price and any discount granted are specifically agreed between the parties, there are in practice no uncertainties associated with revenue recognition from sales of goods. Variable consideration is recognized when there is a high likelihood that there will not be a significant reversal in the amount of the accumulated revenues recognized in the agreement and is measured using the expected value or the most likely amount method, whichever allows to make a better prediction of the amount based on the terms and conditions of the agreement. The products sold by us in general are not returned by customers once they have approved their quality, which occurs at the time of reception. Services rendered We provide transportation services along with the sale of cement, concrete, limestone, and aggregates. Revenues from transportation services are recognized at the time services are provided, which is usually when revenues from the sale of the transported good are recognized as transportation distance and time is very short. Revenue is measured on the basis of the consideration defined in the contract with customers. Revenues from freight railway services and waste recycling services are recognized at the time such services are rendered. Leases Group as Lessee: The accounting model for the recognition and measurement of all leases is as follows: Right of use assets We recognize a right of use asset at the beginning of each lease (the date on which the underlying asset is available for use). Right of use assets are measured at cost, net of accumulated depreciation and impairment losses, and adjusted to reflect any remeasurement of liabilities and to recognize changes in the purchasing power of currency. The cost of the right of use assets includes the amount of the recognized lease liabilities, initial direct costs incurred, and lease payments made at or before the lease start date, less any incentives received. Unless we are certain that it will acquire the asset at the end of the lease, right of use assets are depreciated on a straight-line basis over the shorter of their estimated useful lives and the lease term (calculated based on the term of the relevant agreements, including renewal provisions in the event that they are highly likely to continue). The right of use assets are subject to impairment. We apply the short-term lease recognition exception (i.e., those leases that have a lease term of 12 months or less from the inception date and do not contain a purchase option). We also apply the recognition exception to leases that are considered to be of low value. Payments under these leases are recognized as expense on a straight-line basis over the lease term. 75 Table of Contents Lease liabilities Lease liabilities are measured at the present value of future lease payments to be made throughout the lease term, for which market rates have been used according to the nature and term of each agreement. Lease payments include fixed payments, less any lease incentives to be received, variable payments depending on an index or rate and amounts expected to be paid under residual value guarantees. Lease payments also include the exercise price of any purchase option of the leased underlying asset, and any penalties for terminating the lease, provided that it is reasonably likely that we will exercise such options. Variable payments that do not depend on an index or rate are recognized in profit or loss for the year of occurrence of the condition to which they are subject. The unwinding of the discount recognized for each lease is recorded in the comprehensive income of each year. Group as Lessor: The income from the operating lease of buildings and equipment is recognized every month during the lease term. Leases in which we do not transfer substantially all the risks and rewards inherent to the ownership of the asset are classified as operating leases. The initial direct costs incurred in negotiating an operating lease are in addition to the carrying amount of the leased asset and are recognized throughout the lease term on the same basis as lease income. Foreign currency and functional currency For purposes of the consolidated financial statements, the income (loss) and the financial position of the Group are stated in pesos, considered to be functional currency (the currency of the primary economic environment in which an entity operates) for all group companies and this is also the currency of presentation of the consolidated financial statements. For purposes of presentation of our consolidated financial statements, the assets and liabilities nominated in foreign currency are converted to pesos at foreign exchange rates prevailing at the end of the reporting period and their statement of profit or loss and other comprehensive income are translated at the average foreign exchange rate for each month, unless the corresponding foreign exchange rate has fluctuated significantly during the month, in which case, the exchange prevailing on the date of the transaction is used. Transactions in foreign currencies are initially recorded at their respective functional currency spot rates at the date the transaction first qualifies for recognition. Foreign exchange gains / (losses) from monetary items are recognized in profit and loss for the year, restated at year-end currency, except for those arising from borrowings denominated in foreign currency to financing qualifying assets, such as assets under construction for future productive use, which were included in the cost of such assets for being considered as an adjustment to the cost of interest accrued on such foreign currency denominated borrowings. Borrowing costs Borrowing costs, net of the effect of inflation directly attributed to the acquisition, construction or production of qualifying assets, which are assets that take a substantial period of time to get ready for their intended use or sale, are capitalized as part of the cost of the asset until the assets are ready for use or sale. Income earned on short-term investments of specific outstanding borrowings to finance the construction of qualifying assets is deducted from the borrowing costs that may qualify for capitalization. All the other borrowing costs are recognized in profit or loss when incurred, net of the effect of the inflation on the liabilities that generated them. We have not capitalized interest or exchange differences in the fiscal years ended December 31, 2025, 2024 and 2023. 76 Table of Contents Taxation Argentina Income tax We assess the income tax charge to be booked in accordance with the deferred tax method, which considers the effect of timing differences originating in the different basis for measuring assets and liabilities according to accounting and tax criteria and of the existing net losses and unused tax credits susceptible of deduction of future taxable income computed by considering the tax rate in force. Current taxes Current tax payable is based on the taxable profit for the fiscal year. Taxable profit differs from profit before tax as reported in the consolidated statement of profit and loss and other comprehensive income because of items of income, or expenses that are taxable or deductible in other years and items that will never be taxable or deductible. Our liability for current tax is calculated using the tax rates that have been substantially enacted at the end of the reporting period. Deferred tax Deferred tax is recognized on the temporary differences between the carrying amount of the assets and liabilities included in the consolidated financial statements and the corresponding tax bases used in the computation of taxable profit. Deferred tax liabilities are generally recognized for all future taxable temporary differences. Deferred tax assets are recognized for all deductible temporary differences to the extent that we are likely to have future tax profit against which it is possible to account for those deductible temporary differences. Such deferred tax assets and liabilities are not recognized when temporary difference arose from goodwill or the initial recognition (other than in a business combination) of other assets and liabilities in a transaction that affects neither the taxable nor the accounting profit and does not give rise to equal taxable and deductible temporary differences. The carrying amounts of deferred tax assets are reviewed at the end of each fiscal year and derecognized to the extent it is no longer probable that sufficient taxable profit will be available to allow all or part of the asset to be recovered. Deferred tax assets and liabilities are measured at the tax rates that are expected to apply in the fiscal year when the asset is realized or the liability is settled, based on tax rates (and tax laws) that have been enacted or substantially enacted at the end of the reporting period. Measurement of deferred tax liabilities and deferred tax assets at the end of fiscal year being reported reflects the tax consequences that would stem from the manner in which the entity expects to recover or settle the carrying amount of its assets and liabilities. We offset deferred tax assets and deferred tax liabilities if and only if a) it has legally enforceable right to set off current taxes and current liabilities and b) the deferred tax assets and liabilities relate to income taxes levied by the same tax authority on either the same taxable entity or different taxable entities and we intend either to settle current tax liabilities and assets on a net basis, or to realize the assets and settle the liabilities simultaneously, in each future period in which significant amounts of deferred tax liabilities or assets are expected to be settled or recovered. Deferred tax liabilities are recognized for taxable temporary differences associated with investments in subsidiaries and associates, except where we are able to control the reversal of the temporary difference and it is probable that temporary differences will not reverse in the foreseeable future. Deferred tax assets arising from deductible temporary differences associated with such investments are recognized only to the extent it is probable that there will be sufficient taxable profit to use the benefits of temporary differences and they are expected to reverse in a foreseeable future period. Current and deferred taxes Current and deferred taxes are recognized in the statement of profit and loss and other comprehensive income, except when they relate to items that are recognized in other comprehensive income or directly in equity, in which case, the current and deferred taxes are also recognized in other comprehensive income or directly in equity, respectively. When current tax or deferred taxes arise from a business combination, the tax effect is included in the accounting for the business combination. 77 Table of Contents Personal asset tax—Substitute responsible Argentine resident individuals and non-Argentine resident individuals and entities, are subject to a personal asset tax at a rate of 0.50% over of the equity value of any shares or the American Depositary Shares issued by Argentine entities, held as of December 31 of each year. The tax is on the Argentine issuers of said shares, who must pay for this tax on behalf of the relevant shareholders. In accordance with the Personal Asset Tax Law, we are entitled to obtain a reimbursement of the tax paid from the shareholders levied with the above-mentioned tax through the reimbursement mechanism that the we deem advisable. Property, plant and equipment Property, plant and equipment held for use in the production or supply of goods and services, or for administrative purposes, are recorded at their cost restated in constant currency at the end of the reporting period, in accordance with Note 2.2 to our audited consolidated financial statements, less accumulated depreciation and impairment loss. The cost includes the stripping and initial preparation of the open pit quarries, and the counterpart for the environmental restoration and/or dismantling obligations recognized. It also includes borrowing costs for long-term construction projects if the recognition criteria are met. When significant parts of plant and equipment are required to be replaced at intervals, we depreciate them separately based on their specific useful lives. Likewise, when a major inspection is performed, its cost is recognized in the carrying amount of the plant and equipment as a replacement if the recognition criteria are satisfied. All other repair and maintenance costs are recognized in profit or loss as incurred. The lands owned by Loma Negra are not subject to depreciation. Construction in progress for administrative, production, supply or other purposes are carried at cost restated in constant currency at the end of the reporting period less any recognized impairment loss. Depreciation of Property, Plant and Equipment commences when such assets are ready for their intended use. Property, plant and equipment are depreciated, except for land and assets under construction, over their estimated useful lives using the straight-line method. The estimated useful life, the residual value and the depreciation method are reviewed at the end of each fiscal year, with the effect of any changes in estimates being accounted for on a prospective basis. Gain or loss from the disposal or write-off of an item of property, plant and equipment is calculated as the difference between net disposal proceeds and the carrying amount of the asset and is recognized in profit or loss at its value restated at the year-end currency. We assess the recoverability of the value of its property, plant and equipment items whenever any indication of impairment is identified. The assessments are carried out considering the cash-generating units established by us. Intangible assets Intangible assets with finite useful lives, acquired separately, are recorded at cost, restated in the currency at the closing date less accumulated amortization and less accumulated impairment losses. The estimated useful lives and amortization method are reviewed at each year-end, with the effect of any changes in these estimates recorded prospectively. Intangible assets with indefinite useful lives that are acquired separately are recorded at cost restated in the currency at the closing date less accumulated impairment losses. An intangible asset is derecognized when no future economic benefits are expected from its use or disposal. Gains or losses arising from the derecognition of an intangible asset, measured as the difference between the net proceeds from the derecognition and the asset's carrying amount, are recognized in earnings when the asset is derecognized. 78 Table of Contents Impairment of tangible and intangible assets with finite useful lives At the end of each period, we review if any indication that tangible and intangible assets might be impaired. In case of impairment indicators are observed, we calculate the recoverable amount per cash-generating unit. The recoverable amount of an asset is the higher of the fair value less cost of disposal and its value in use. In assessing value in use, the estimated future cash flows are discounted using a pre-tax discount rate that reflects current market assessments as of year-end with respect to the time value of money considering the risks that are specific to the asset. If the recoverable value of an asset (or cash-generating unit) is estimated to be less than its carrying amount, the carrying value of the asset (or cash-generating unit) is reduced to its recoverable value. Impairment losses are immediately recognized in profit or loss. When a recognized impairment loss is subsequently reversed, the book value of the asset is increased up to the new recoverable amount but the reversal is limited so that the carrying amount of the asset does not exceed the carrying amount that would have been determined, net of depreciation, had no impairment loss been recognized for the asset or CGU in prior years. Impairment loss reversals are immediately recognized in profit loss. Impairment losses related to goodwill are not reversed in future periods. Inventories Inventories are stated at the lower of cost restated in constant currency at the end of period and net realizable value. Costs incurred in bringing products to their present condition are accounted for as follows: •Raw materials and spare parts: at acquisition cost according to the weighted average price method. •Finished goods and work in progress: at acquisition cost of raw materials and labor, plus a proportion of manufacturing overheads based on normal operating capacity. The net realizable value is the estimated selling price in the ordinary course of business, less estimated costs of completion and the estimated costs necessary to make the sale. In assessing recoverable amounts of inventories, slow-moving inventories are also considered. The carrying amount of inventories as of the fiscal year-end does not exceed their recoverable value. Provisions We recognize provisions when we have a present obligation (legal or constructive) as a result of a past event, it is probable that an outflow of resources embodying economic benefits will be required to settle the obligation and a reliable estimate can be made of the amount of the obligation. Estimated amounts of the obligation are based on the expected outflows that will be required to settle such obligation. If the effect of the time value of money is material, provisions are discounted using a current pre-tax rate that reflects, when appropriate, the risks specific to the liability. When we expect some or all of a provision to be reimbursed, the reimbursement is recognized as a separate asset (a receivable), but only when the reimbursement is virtually certain and the amount of the receivable can be reliably measured. We use the opinion of our legal advisors to determine if a provision should be recorded as well as to estimate the amounts of the obligations. Environmental restoration and asset decommissioning obligations Under legal provisions and best practices, and the environmental commitments assumed by the Group, land used by the Group for mining and quarrying is subject to environmental restoration, and the fixed assets used in production will be removed at the end of operations. In this context, provisions are recognized as long as they are determinable, in order to afford the estimated expenses for the environmental recovery and restoration of the mining areas and the retirement of the corresponding 79 Table of Contents productive assets. These provisions are recorded simultaneously with the increase in value in the underlying asset and the relevant depreciation of the assets involved is recognized in profit and loss prospectively. The liability recorded is increased due to the unwinding of the discount and this change is charged to net profit or loss. The environmental restoration and asset retirement obligation can also increase or decrease due to changes in the estimated timing of cash flows, changes in the discount rate and/or changes in the original estimated undiscounted costs. In estimating the expected cost, the Group takes into account changes in environmental legislation and regulations, if any, that may impact the process and restoration and dismantling costs. Increases or decreases in the obligation other than the unwinding of discount will result in a corresponding change in the carrying amount of the related asset. Actual costs incurred upon settlement of the asset retirement obligation are charged against the asset retirement obligation to the extent of the liability recorded. We discount the costs related to asset retirement obligations using the discount rate that reflects the current market assessment of the time value of money and risks specific to the liabilities that have not been reflected in the cash flow estimates. Asset retirement obligations are remeasured at each reporting period in order to reflect the discount rates in effect at that time. In addition, we follow the practice of progressively restoring the areas by the removal of quarries using the provisions recognized for that purpose. Provisions for lawsuits and other contingencies The final settlement cost of complaints and litigation may vary due to estimates based on different interpretations of regulations, opinions and final assessments of damages. Therefore, any change in the circumstances related to this type of contingencies may have a significant impact on the amount of the provision for contingencies recorded. In the normal course of its business, we select tax criteria and accounting positions based on a reasonable interpretation of the current regulations, also taking into consideration the opinion of its tax and legal advisors along with evidence available up to the date of issuance of these financial statements. Nevertheless, in the event of situations where the assessment by a third party and the potential occurrence of damage for the Group are uncertain, the Group does not record a provision as it is has not been required under IFRS Accounting Standards. The Group makes judgments and estimates to assess whether it is necessary to record costs and make provisions for environmental cleanup remediation and asset retirement obligations based on the current information related to expected remediation costs and plans. In the case of environmental provisions, costs may differ from estimates due to changes in laws and regulations, discovery and analysis of local conditions, as well as changes in cleanup technologies. Therefore, any change in the factors or circumstances related to this type of provisions, as well as any amendment to the rules and regulations may thus have a significant impact on the provisions recorded our financial statements. Financial instruments A financial instrument arises from any contract that results in the recognition of a financial asset in one entity and a financial liability or equity instrument in another entity. Financial assets and financial liabilities are initially measured at fair value. Transaction costs that are directly attributable to the acquisition or issue of financials assets and financial liabilities (other than financial assets and liabilities at fair value through profit or loss) are added or deducted from the fair value of the financial assets of financial liabilities, as appropriate, on initial recognition. Transactions costs directly attributable to the acquisition of financial assets or financial liabilities at fair value through profit or loss are recognized immediately in profit or loss. Interest and financial income are recognized to the extent the effective interest rate is accrued. In general, the Group may receive short-term advances from its customers. Pursuant to the practical expedient of IFRS 15, the Group does not adjust the promised amount of consideration for the effects of a significant financing component if it expects, at contract inception, that the period between the entity transfers a promised good or service to a customer and when the customer pays for that good or service will be one year or less. The Group does not receive any long-term advances from its customers. 80 Table of Contents Financial assets According to the provisions under IFRS 9 “Financial instruments”, we classify for purposes of subsequent measurement our financial assets into the following two categories because the company has not asset that are designated as fair value through other comprehensive income: Financial assets at amortized cost A financial asset is measured at amortized cost if both of the following conditions are met: (i) the asset is held within a business model whose objective is to hold assets in order to collect contractual cash flows; and (ii) the contractual terms of the financial asset give rise on specified dates to cash flows that are solely payments of principal and interest on the principal amount outstanding. In addition, for the assets that satisfy the conditions mentioned above, IFRS 9 provides the option of designating at the time of initial recognition, an asset as measured at reasonable value if in doing so it eliminates or significantly reduces an inconsistency in valuation or recognition that would have arisen if the valuation of the assets or liabilities or the recognition of their income or loss were effected on different bases. We have not designated any financial asset at fair value using this option. As of December 31, 2025 and 2024, our financial assets at amortized cost comprise certain cash and cash equivalent elements, accounts receivable, trade and other receivables. Financial assets at fair value through profit or loss If one of the criteria mentioned above were not satisfied, the financial asset is classified as an asset measured at “fair value through profit or loss”. At the date of our consolidated financial statement contained herein our financial assets at fair value through profit or loss include mutual funds classified as current investments. Recognition and measurement Acquisitions and disposals of financial assets are recognized on the date on which our promises to purchase or sell the asset. Financial assets are derecognized when the rights to receive cash flows from such instruments and the risks and benefits related to their ownership have been terminated or assigned. Financial assets at amortized cost are initially recognized at fair value plus transaction costs. These assets accrue interest based on the effective interest rate method. Financial assets at fair value through profit or loss are initially recognized at fair value and transaction costs are recognized as expenses in the statement of profit or loss and other comprehensive income. They are subsequently measured at fair value. Changes in fair values and gains or losses on the sale of financial assets at fair value through profit or loss are recognized in “Financial results, net” in the statement of profit or loss and other comprehensive income. In general, we use the transaction price to determine the fair value of a financial instrument at initial recognition. In all other cases, we only records a gain or loss at initial recognition if the fair value of the instrument is evidenced by other comparable and observable market transactions for the same instrument or is based on a valuation technique incorporating only observable market data. Any gains or losses not recognized at initial recognition of a financial asset are subsequently recognized only to the extent that they arise from a change in factors (including time) that market participants would consider in establishing the price. The results of debt instruments that are measured at amortized cost and are not designated in a hedging relationship are recognized in the profit or loss and other comprehensive income statement using the effective interest rate method. The Group reclassifies between categories all investments in debt instruments only when there is a change in the business model used to manage such assets. 81 Table of Contents Financial asset impairment At the end of each period, we assess if there is objective evidence of impairment of a financial asset or group of financial assets measured at amortized cost. Impairment is recorded only if there is objective evidence of the impairment as a consequence of one or more events occurred after the initial recognition of the asset and said impairment may be reliably measured. The Group defined a policy to calculate expected credit losses for trade receivables and record the related allowance for debtors’ impairment. The determination of the expected loss is initially based on the Group’s historical observed default rates and it is complemented by a case by case analysis to identify special circumstances on individual customers and/or transactions. This bad debt percentage must take into account expected future credit collections and, therefore, any estimated changes in behavior. Before accepting any new customer, the Group conducts an internal credit analysis to assess the potential customer's creditworthiness and define their credit limit. The limits and ratings assigned to major customers are reviewed at least once a year. Evidence of impairment includes indications that the debtors or a group of debtors are experiencing serious financial difficulties, default or arrears in interest or principal payments, the likelihood that they will be declared bankrupt or file for reorganization proceedings, and when such observable data indicates that there is a decrease in the estimated future cash flows. The amount of the impairment is measured as the difference between the book value of the asset and the present value of estimated future cash flows (excluding future loan losses that have not been incurred) discounted at the original effective interest rate of the financial asset. The carrying amount of the asset is written down and the amount of the loss is recognized in the profit or loss and other comprehensive income. As a practical measure, we may measure impairment on the basis of the fair value of an instrument, using an observable market price. If, in a subsequent period, the impairment amount decreases and such reduction is related to an event taking place after the original impairment, the reversal of the impairment loss is recognized in the consolidated statement of profit or loss and other comprehensive income. Offsetting of financial instrument Financial assets and financial liabilities are offset if there is a currently enforceable legal right to offset the recognized amounts and when there is an intent to settle on a net basis, to realize the asset and settle the liability simultaneously. Derecognition of a financial asset A financial asset (or, where applicable, a part of a financial asset or part of a group of similar financial assets) is primarily derecognised (i.e., removed from the Group’s consolidated statement of financial position) when: •The rights to receive cash flows from the asset have expired, or •We transferred its rights to receive cash flows from the asset or has assumed an obligation to pay the received cash flows in full without material delay to a third party under a ‘pass-through’ arrangement; and either (a) we have transferred substantially all the risks and rewards of the asset, or (b) we have neither transferred nor retained substantially all the risks and rewards of the asset, but has transferred control of the asset When the Group has transferred its rights to receive cash flows from an asset or has entered into a pass-through arrangement, it evaluates if, and to what extent, it has retained the risks and rewards of ownership. When it has neither transferred nor retained substantially all of the risks and rewards of the asset, nor transferred control of the asset, the Group continues to recognize the transferred asset to the extent of its continuing involvement. In that case, the Group also recognizes an associated liability. The transferred asset and the associated liability are measured on a basis that reflects the rights and obligations that the Group has retained. Continuing involvement that takes the form of a guarantee over the transferred asset is measured at the lower of the original carrying amount of the asset and the maximum amount of consideration that the Group could be required to repay. 82 Table of Contents Financial liabilities and equity instruments Classification as debt or equity Debt and equity instruments are classified as financial liabilities or as equity in accordance with the substance of the contractual agreement and the definitions of financial liabilities and equity instruments. Equity instruments An equity instrument consists in a contract evidencing a residual ownership interest over an entity’s net assets after deducting all its liabilities. Equity instruments issued by us are recognized at the amount of proceeds received, net of direct issuance costs. The repurchase of our own equity instruments is recognized and deducted directly in equity. No gain or loss is recognized in profit or loss stemming from purchases, sales, issuance or cancellation of our own equity instruments. Note 3.16 to our audited consolidated financial statements discloses the valuation and classification criterion for all individual equity accounts, including non-controlling interest. Financial Liabilities: Financial liabilities are classified as at fair value through profit or loss or other financial liabilities. The Group does not have financial liabilities that arise from supplier finance arrangement. Financial liabilities at fair value through profit or loss: A financial liability at fair value through profit or loss is a financial liability classified either as held for trading or at fair value through profit or loss. Financial liabilities are classified as held for trading if: a)It has been acquired or incurred principally for the purpose of selling or repurchasing it in the near term; or b)At the time of initial recognition, the liabilities are part of a portfolio of financial instruments that are managed by the Group and there is evidence of a recent current pattern of short-term profit; or c)It is a derivative that has not been designated and is not effective as a hedging instrument or financial guarantee. Financial liabilities at fair value through profit or loss are recorded at fair value, with any gains or losses arising from the remeasurement being recognized in profit or loss. The net gain or loss recognized in profit or loss includes any interest paid on the financial liability and is included in other financial results. Fair value is determined as described in Note 32 of our consolidated financial statements. Financial liabilities (other than financial liabilities held for trading) or contingent consideration to be paid by an acquirer as a part of a business combination may be designated as a liability at fair value through profit and loss upon initial recognition if: •Such designation eliminates or significantly reduces a potential accounting mismatch that would otherwise arise; or •Financial liabilities are part of a group of financial assets or liabilities or both, which is managed and whose performance is assessed on the basis of fair value, in accordance with the Group’s documented risk management or investment strategy, and information about the Group is provided internally on that basis; or •They are part of a contract containing one or more embedded derivatives, and IFRS 9 allows the entire combined contract to be carried at fair value through profit and loss. We have no financial liabilities measured at fair value to be presented in the statement of financial position. Other financial liabilities: Other financial liabilities, including borrowings and trade and other payables, are initially recognized at fair value, net of transaction costs. 83 Table of Contents Subsequent to initial recognition, other financial liabilities are then measured at amortized cost using the effective interest rate method, with interest expense recognized based on actual return. Financial liabilities are classified as current liabilities unless the Group has an unconditional right to defer settlement for more than twelve months after the date of the financial statements. Financial liabilities in foreign currency: The fair value of financial liabilities in foreign currency is determined in that foreign currency and translated at the exchange rate at the end of each fiscal year. The foreign currency component is part of its profit or loss at fair value. For financial liabilities classified as at fair value through profit or loss, the foreign currency component is recognized in profit or loss. For debt instruments denominated in foreign currency classified at amortized cost, gains and losses in foreign currency are determined on the basis of the amortized cost of the liability and recognized in “Exchange rate differences” under the “Financial results net” in the statement of profit or loss and other comprehensive income. Derecognition of financial liabilities: We derecognize financial liabilities if, and only if, the obligations of the Group expire, are settled or satisfied. Short- and long-term employee benefits Liabilities are recognized for the benefits accrued in favor of employees with respect to the salaries and wages, annual vacations and leaves of absence due to diseases in the period in which the service is rendered in connection with the non-discounted amount of the benefits expected to be paid in exchange for such service. Liabilities recognized with respect to other long-term employee benefits (severance payment plans resulting from specific plans for employees leaving the Group and receiving a compensation payable in installments) are measured at the present value of estimated future cash outflows expected to be paid. See Note 3.17 to our audited consolidated financial statements , and "Item 6.A. Directors, Senior management and Employees" and "Item 6.B. Compensation" of this annual report for information about the current employee benefit plans. Until November 2024, the cost of the share-based payment plans to be settled with equity instruments issued under the existing program was measured at fair value at the date of each grant and it was recognized as "Salaries, wages, and social security contributions" in the comprehensive income over the period in which the performance and/or service conditions were met, with a corresponding entry to “Share-based payment plans” in shareholders' equity. During the month of November 2024, the outstanding balance of the active plans that was maintained in equity was reclassified to liabilities considering that it is the intention of the Group's Management to settle the plans in cash. The liability is measured at fair value at the end of each fiscal year, with a corresponding charge to comprehensive income statement under the account "Salaries, wages, and social security contributions". Stripping and quarry exploitation costs In the ordinary course of business, the company undertakes several exploration and evaluation activities in order to search for mineral ore and determine the technical and commercial feasibility of the resources identified. Exploration and evaluation activities include research and analysis of historical exploration data, the compilation of exploration data through geological studies, exploratory drilling and sampling in several areas, the determination of the volume and qualification of the resources identified, among others. Following the guidelines established by IFRIC 20 "Uncovering costs in the production phase of an open-pit mine", the costs of uncovering and initial preparation of open-pit quarries for subsequent exploitation are capitalized as property, plant and equipment, as part of the development and uncovering costs of the Company's open-pit quarries, and are subsequently depreciated based on the units extracted, considering for this purpose the estimate of the reserves available for extraction and existing in the uncovered area at any given time. Periodically, the Group re-evaluates the estimate of the proven reserves in the uncovered quarries and prospectively adjusts the effects of any differences in the estimate of the tonnes available for extraction. Due to the periodicity of the reviews of the estimates, the risk of significant differences in them is reduced. 84 Table of Contents Extraction costs incurred subsequently during the Company's production phase are recognized as part of the cost of production. Mineral rights acquired in connection with the right to explore existing exploration areas are capitalized and amortized during the term of the right. As soon as a legal right has been acquired to explore, exploration and evaluation costs are expensed as incurred to profit or loss, unless the company’s management arrives at the conclusion that there is a highest likelihood of obtaining future profits; when this is the case, costs are capitalized. In assessing whether the costs satisfy the criteria to be capitalized several information sources are used, including the nature of the assets, the surface area explored and the results of the samples taken, among others. All capitalized stripping, exploration and evaluation costs are subject to impairment testing. In the case of determining a potential impairment indicator, the company carries out an assessment of its recoverability together with the group of related operating assets, which represents the cash-generating unit to which the exploration is attributed. Ferrosur Roca S.A. concession Management has reviewed the Group’s interest in Ferrosur Roca S.A., taking into account the provisions of IFRIC 12 Service Concession Arrangements, which provides guidance on accounting by the operators of public-to-private service concession arrangements. Based on the fact that the grantor neither controls nor regulates which services should be provided by the operator to the infrastructure or to whom it must provide them, and at what price, the company's management concluded that the Ferrosur Roca S.A. concession is out of the scope of IFRIC 12 and, therefore, the Group does not apply its provisions. Accordingly, the Group has recorded the assets received from the concession and those subsequently acquired under IAS 16 - Property, Plant and Equipment. The concession bidding terms and conditions grant an original term of thirty years (1993-2023) and originally provided for the possibility of an extension for ten additional years, which was rejected by the Ministry of Transport for the reasons described in Note 36 to the consolidated financial statements. The Ministry of Transport provisionally issued resolutions granting extensions to the concession for terms of 12 and 18 months to the different concessionaires, including Ferrosur Roca S.A. Therefore, the concession of Ferrosur Roca S.A. has been extended for the third time and will end in September 2026 or an earlier date on which a new contracting model can be established. The Group has reassessed all the accounting estimates affected to the end of the current concession and the continuation of its activities, taking into account available information and has not anticipated significant associated effects to date. Likewise, it has reassessed all the accounting estimates affected to the end of the current concession, especially those associated with the recoverability of certain non-current assets affected by it. See Note 36 to our audited consolidated financial statements. Management’s accounting estimates and judgments on environmental matters The Group is constantly working on a responsible and sustainable business strategy, committed to improving environmental performance on an ongoing basis, minimizing environmental impact caused by its operations, and providing maximum value for society. To this end, we have set various environmental sustainability goals within the medium term (year 2030) and long term (year 2050), in alignment with the 2030 Agenda Sustainable Development Goals (“SDG”) promoted by the United Nations. The main committed goals are related to maximizing energy efficiency and renewable energy, reducing gas emissions and improving air quality, reducing the carbon footprint, maximizing water management, streamlining waste management by promoting circular economy, and improving efficiency in the use of materials. In preparing the consolidated financial statements, the Group's management has considered the potential environmental impact. Therefore, the estimates and judgments made by the Group's management primarily involve assumptions related to future regulations and performance of the industry in which the Group operates. The effects of changes in the estimates and judgments made may primarily relate to impairment tests on property, plant and equipment, the estimated useful life of fixed those assets and therefore the related depreciation recognized annually, as well as the 85 Table of Contents recognition of provisions, such as the environmental provision to afford the estimated expenses for the environmental recovery and restoration of the mining areas exploited by the Group. Components of Certain Statement of Profit or Loss and Other Comprehensive Income Line Items Revenues Our revenues are derived by deducting discounts to clients from our gross sales revenue. Practically all of our gross sales revenue is denominated in pesos and is derived primarily from our sale of cement products, concrete, aggregates and railway services. Cost of Sales Our cost of sales consists of electrical power, manual labor, contractors, depreciation and amortization, freight, packaging and other costs. The following table sets forth the percentage of our total cost of sales that each such component represented for the years ended December 31, 2025, 2024 and 2023.

The non-cash components of our financial income (expenses), net, include foreign exchange variation. For a description of our outstanding indebtedness as of December 31, 2025, see “Item 5.B. Operating and Financial Review and Prospects—Liquidity and Capital Resources”. Income Tax Expense Income tax expense includes current and deferred taxes. Current income tax is measured as the amount expected to be paid (or recovered, to the extent applicable) to tax authorities based on the taxable profit for the period. Deferred taxes includes the effect of temporary differences originating in the different basis for measuring assets and liabilities according to accounting and tax criteria and of the existing net losses and unused tax credits susceptible of deduction of future taxable income computed by considering the tax rate. Results of Operations In the following discussion, references to increases or decreases in any period are made by comparison with the prior period, except as the context otherwise indicates. For a reconciliation of the operating results of our operating segments for the periods indicated to our consolidated results of operations, see Note 31 to our audited consolidated financial statements included elsewhere in this annual report. 87 Table of Contents Year Ended December 31, 2025, compared to the Year Ended December 31, 2024 The following table sets forth our consolidated statement of profit or loss and other comprehensive income for 2025 and 2024: For the Year Ended December 31, Variation 2025 2024 Amount (%) (in millions of Ps., except percentages) Revenue 848,086.6 919,760.9 (71,674.3) (7.8) Cost of sales (663,079.9) (673,789.8) 10,709.9 (1.6) Gross profit 185,006.7 245,971.1 (60,964.4) (24.8) Selling and administrative expenses (94,344.8) (96,261.3) 1,916.5 (2.0) Other gains and losses 4,812.8 5,992.4 (1,179.6) (19.7) Tax on debits and credits to bank accounts (9,032.8) (9,761.4) 728.6 (7.5) Finance costs, net Exchange rate differences (85,133.2) (57,498.0) (27,635.2) 48.1 Gain on net monetary position 90,039.2 345,814.7 (255,775.5) (74.0) Financial income 3,976.7 2,582.2 1,394.5 54.0 Financial expenses (57,959.6) (108,557.4) 50,597.8 (46.6) Profit before taxes 37,365.1 328,282.3 (290,917.2) (88.6) Income tax expense Current (19,511.7) (87,414.4) 67,902.7 (77.7) Deferred 4,967.2 (38,774.1) 43,741.3 (112.8) Net profit 22,820.5 202,093.8 (179,273.3) (88.7) 88 Table of Contents Revenues Our revenues decreased Ps. 71,674 million, or 7.8%, from Ps. 919,761 million in 2024 to Ps. 848,087 million in 2025, mainly driven by lower revenues in our core cement segment, while the other segments delivered mixed performance. The following tables set forth our sales volume and average price for each segment for the years indicated: Sales Volume For the Year Ended December 31, 2025 2024 % Variation Cement, masonry & lime MM Tn 5.02 4.90 2.5 Concrete MM m3 0.56 0.40 42.7 Railroad MM Tn 3.93 3.63 8.2 Aggregates MM Tn 1.15 0.97 19.1 Ps./Sales volumes For the YearEnded December 31, 2025 2024 % Variation Cement, masonry & lime Ps./Tn 146,722 166,512 (11.9) Concrete Ps./m3 140,531 184,907 (24.0) Railroad Ps./Tn 19,788 23,493 (15.8) Aggregates Ps./Tn 18,981 23,482 (19.2) •Cement, masonry cement and lime segment: Revenues from our cement, masonry cement and lime segment, without considering the eliminations between segments, decreased Ps. 79,162 million, from Ps. 815,507 million in 2024 to Ps. 736,345 million in 2025, mainly due to a decrease of 11.9% in sales price, reflecting softer pricing conditions, partially offset by a 2.5% increase in sales volume. The recovery after the first half of the year slowed down amid electoral and financial uncertainties that impacted the level of activity and cement demand recovery in the second half of the year. Bulk cement dispatches showed improved performance driven by increased activity in larger construction or infrastructure projects, while bagged cement, more related to retail consumption, remained lagging in terms of recovery. As our cement segment also includes masonry cement and lime, which performed similarly to bagged cement, this weighed on overall segment growth and resulted in performance below that of the broader cement industry, which only reflects gray cement volumes. •Concrete segment: Revenues from our concrete segment, without considering the eliminations between segments, increased Ps. 6,171 million, from Ps. 73,201 million in 2024 to Ps. 79,372 million in 2025, mainly due to an increase of 42.7% in sales volume, which compensated for softer pricing dynamics in a highly competitive environment, where the average sales price decreased by 24%. In line with bulk cement dispatches, concrete demand showed a stronger recovery, underpinned by industrial projects and a moderate reactivation of public works. •Railroad segment: Revenues from our railroad segment, without considering the eliminations between segments, decreased Ps. 7,578 million, from Ps. 85,380 million in 2024 to Ps. 77,802 million in 2025. The increase of 8.2% in sales volume only partially offset the softer pricing conditions, where the average sales price decreased by 15.8%. While cement volumes transported remained almost flat, the significant increase in granitic aggregates more than offset the decline in gypsum and frac sand, both of which were affected by the disruption of the railway line connecting Bahía Blanca and Neuquén. •Aggregates segment: Revenues from our aggregates segment, without considering the eliminations between segments, decreased Ps. 853 million, from Ps. 22,717 million in 2024 to Ps. 21,864 million in 2025 mainly due to a decrease of 19.2% in average price, partially offset by a 19.1% increase in sales volume. 89 Table of Contents •Others segment: Revenues from Recycomb S.A.U., without considering the eliminations between segments, increased Ps. 2,940 million, from Ps. 9,149 million in 2024 to Ps. 12,089 million in 2025. Cost of sales Our cost of sales decreased Ps. 10,710 million, or 1.6%, from Ps. 673,790 million for 2024 to Ps. 663,080 million for 2025, mostly as a consequence of the decrease in unit costs in our cement segment. The main contributors to our cost of sales decrease during the period were (1) Ps. 11,614 million in thermal and electrical energy costs, due to a lower impact of energy input prices on our cost of sales; (2) Ps. 9,033 million in lower maintenance expenses, mainly due to the lower increase of costs against inflation; and (3) Ps. 2,327 million in lower costs of contractors. These production expense items have decreased more than the impact of cost increases from (1) depreciation and amortization by Ps. 5,206 million, (2) freight and tolls by Ps. 2,831 million and (3) packaging by Ps. 3,309 million. The following table sets forth the reconciliation of our production costs to our cost of sales for the years indicated: As of and for the Year Ended December 31, 2025 2024 (in millions of Ps.) Purchases and production expenses for the year 685,735.6 743,252.8 (+) Inventories at the beginning of the year 353,511.3 284,048.2 (-) Inventories at the end of the year 376,167.0 353,511.3 Cost of sales 663,079.9 673,789.8 The cost of sales of our segments is set forth below, eliminations between segments are not considered: •Cement, masonry cement and lime segment: Cost of sales from our cement, masonry cement and lime segment, without considering the eliminations between segments, decreased Ps. 18,022 million, or 3.2%, from Ps. 565,189 million in 2024 to Ps. 547,167 million in 2025. This decrease in cost of sales was mainly due to (1) lower thermal and electrical energy costs as a consequence of lower unitary costs; (2) a decrease in preservation and maintenance costs; and (3) lower costs of contractors. •Concrete segment: Cost of sales from our concrete segment, without considering the eliminations between segments, increased Ps. 6,706 million, or 8.7%, from Ps. 77,418 million in 2024 to Ps. 84,124 million in 2025. This increase in the cost of sales was mainly due to the higher sales volume partially offset by a decrease in equipment rental and other fixed costs. •Railroad segment: Cost of sales from our railroad segment decreased Ps. 8,394 million, or 9.9%, from Ps. 85,075 million in 2024 to Ps. 76,681 million in 2025, mainly due to lower costs of maintenance materials, depreciation and amortization. •Aggregates segment: Cost of sales from our aggregates segment increased Ps. 1,974 million, or 7.4%, from Ps. 26,612 million in 2024 to Ps. 28,586 million in 2025. This increase was primarily due to the higher volume of sales, partially offset by lower costs of maintenance materials and services and lower equipment rental costs. •Others segment: Cost of sales from Recycomb S.A.U. segment increased Ps. 218 million, or 3.8%, from Ps. 5,689 million in 2024 to Ps. 5,907 million in 2025. Gross profit Due to the factors mentioned above, our gross profit decreased Ps. 60,964 million, or 24.8%, from Ps. 245,971 million in 2024 to Ps. 185,007 million in 2025. Our gross margin (gross profit divided by revenues and expressed as a percentage) contracted by 493 basis points, from 26.7% in 2024 to 21.8% in 2025. 90 Table of Contents Selling and administrative expenses Our selling and administrative expenses decreased Ps. 1,916 million, or 2.0%, from Ps. 96,261 million in 2024 to Ps. 94,345 million in 2025, mainly due to (1) a decrease in freight due to lower input costs; (2) a decrease in advertising expenses; and (3) a decrease in fees and compensation for services, that have compensated the higher charge of data processing expenses and allowance for doubtful accounts. Other gains and losses Our other gains and losses decreased Ps. 1,179 million, or 19.7%, from a net gain of Ps. 5,992 million in 2024 to a net gain of Ps. 4,813 million in 2025, mainly attributable to a decrease in gains on the disposal of property, plant and equipment, which was partially offset by lower gains recognized on the acquisition of tax credits. The remaining components of other gains and losses did not present material variations in the period. Tax on bank accounts debits and credits Our tax on bank accounts debits and credits decreased Ps. 729 million, or 7.5%, from Ps. 9,761 million in 2024 to Ps. 9,033 million in 2025, related to the amount of monetary transactions carried out during 2025, that trigger the mentioned tax. Financial results, net Our total net financial cost increased Ps. 231,418 million, from a gain of Ps. 182,341 million in 2024 to a loss of Ps. 49,077 million in 2025, mainly due to (1) a decrease in gain on net monetary position of Ps. 255,776 million; (2) an increase of Ps. 27,635 million in loss due to exchange rate differences due to the increased devaluation of the local currency; (3) a lower charge of Ps. 28,601 million from interest on borrowings due to lower average interest rates during 2025; (4) a higher profit of Ps 560 million from temporary investments; and (5) a decrease in interest on other payables of Ps. 8,307 million. Our financial expenses decreased Ps. 50,597 million, or 46.6%, from Ps. 108,557 million in 2024 to Ps. 57,960 million in 2025, mainly due to a lower impact of Ps. 28,601 million from interest on borrowings and Ps. 8,307 million in interest on other payables. Our financial income decreased Ps. 1,395 million, or 54%, from Ps. 2,582 million for 2024 to Ps. 3,977 million for 2025. Income tax expense Our income tax expense decreased Ps. 111,643 million, or 88.5%, from Ps. 126,188 million in 2024 to Ps. 14,545 million in 2025 mainly due to the decrease in profit for the year 2025 compared to that of 2024, affected by the hyperinflation adjustments for income tax determination. The resulting effective tax rate was 38.9% in 2025 compared to 38.4% in 2024. 91 Table of Contents The following table presents our effective tax rate reconciliation for each year. For the year ended December 31, 2025 2024 (amounts in millions of Ps.)

Our deferred income tax expense decreased Ps. 43,741 million or 112.8%, from a loss of Ps. 38,774 million in 2024 to a gain of Ps. 4,967 million in 2025, mainly due to the impact during 2024 of using the tax loss carryforwards existing as of December 31, 2023. Net profit As a result of the foregoing, our net profit decreased Ps. 179,275 million, or 88.7%, from Ps. 202,094 million in 2024 to Ps. 22,821 million in 2025. Our net margin (net profit divided by revenues and expressed as a percentage) decreased by 1,928 basis points, from 22.0% in 2024 to 2.7% in 2025. 92 Table of Contents Year Ended December 31, 2024, compared to the Year Ended December 31, 2023 The following table sets forth our statement of profit or loss and other comprehensive income for 2024 and 2023: For the Year Ended December 31, Variation 2024 2023 Amount (%) (in millions of Ps., except percentages) Revenue 919,760.9 1,209,344.5 (289,583.6) (23.9) Cost of sales (673,789.8) (905,956.9) 232,167.1 (25.6) Gross profit 245,971.1 303,387.6 (57,416.5) (18.9) Selling and administrative expenses (96,261.3) (110,763.9) 14,502.6 (13.1) Other gains and losses 5,992.4 2,629.9 3,362.5 127.9 Tax on debits and credits to bank accounts (9,761.4) (13,396.6) 3,635.2 (27.1) Finance costs, net Exchange rate differences (57,498.0) (335,771.4) 278,273.4 (82.9) Gain on net monetary position 345,814.7 397,500.1 (51,685.4) (13.0) Financial income 2,582.2 16,357.0 (13,774.8) (84.2) Financial expenses (108,557.4) (210,045.5) 101,488.1 (48.3) Profit before taxes 328,282.3 49,897.2 278,385.1 557.9 Income tax expense Current (87,414.4) (10,914.1) (76,500.3) 700.9 Deferred (38,774.1) (11,251.8) (27,522.3) 244.6 Net profit 202,093.8 27,731.3 174,362.5 628.8 93 Table of Contents Revenues Our revenues decreased Ps. 289,584 million, or 23.9%, from Ps. 1,209,345 million in 2023 to Ps. 919,761 million in 2024, primarily due to lower topline performance of our core business, cement, followed by the concrete, aggregates and railroad segments. The following tables set forth our sales volume and average price for each segment for the years indicated: Sales Volume For the Year Ended December 31, 2024 2023 % Variation Cement, masonry & lime MM Tn 4.90 6.42 (23.7) Concrete MM m3 0.40 0.58 (31.8) Railroad MM Tn 3.63 4.20 (13.4) Aggregates MM Tn 0.97 1.29 (24.8) Ps./Sales volumes For the Year Ended December 31, 2024 2023 % Variation Cement, masonry & lime Ps./Tn 166,512 165,175 0.8 Concrete Ps./m3 184,907 199,915 (7.5) Railroad Ps./Tn 23,493 22,698 3.5 Aggregates Ps./Tn 23,482 28,679 (18.1) •Cement, masonry cement and lime segment: Revenues from our cement, masonry cement and lime segment, without considering the eliminations between segments, decreased Ps. 244,406 million, from Ps. 1,059,913 million in 2023 to Ps. 815,507 million in 2024, mainly due to a decrease of 23.7% in sales volume. The transition in the government's administration and the impact of the stabilization plan negatively affected cement demand, especially in the first half of the year. However, as the economy began to recover and stabilize, activity levels improved in the second half. Bagged cement dispatches proved more resilient in this environment, while bulk dispatches were more significantly impacted by the slowdown in activity levels. •Concrete segment: Revenues from our concrete segment, without considering the eliminations between segments, decreased Ps. 42,779 million, from Ps. 115,980 million in 2023 to Ps. 73,201 million in 2024, mainly due to a decrease of 31.8% in sales volume and an average sales price decrease of 7.5%. In line with bulk cement dispatches, concrete demand was more heavily affected by the economic slowdown and the halt in public works, as well as major private projects. •Railroad segment: Revenues from our railroad segment, without considering the eliminations between segments, decreased Ps. 9,914 million, from Ps. 95,294 million in 2023 to Ps. 85,380 million in 2024, mainly due to a decrease of 13.4% in sales volume, partially offset by a 3.5% increase in the average selling price. The significant increase in transported volumes of grains and frac sand helped offset the drop in construction materials and chemicals •Aggregates segment: Revenues from our aggregates segment, without considering the eliminations between segments, decreased Ps. 14,203 million, from Ps. 36,920 million in 2023 to Ps. 22,717 million in 2024 mainly due to a decrease of 24.8% in sales volume and an average price decrease of 18.1%. •Others segment: Revenues from Recycomb S.A.U., without considering the eliminations between segments, increased Ps. 2,330 million, from Ps. 6,819 million in 2023 to Ps. 9,149 million in 2024. Cost of sales Our cost of sales decreased Ps. 232,167 million, or 25.6%, from Ps. 905,957 million for 2023 to Ps. 673,790 million for 2024, mostly as a consequence of the lower sales volume. The main contributors to our cost of sales decrease 94 Table of Contents during the period were (1) Ps. 76,717 million in thermal and electrical energy costs, due to a lower sales volume and a lower impact of energy inputs on our cost of sales; (2) Ps. 31,222 million in lower freight costs, mainly due to lower sales volume; and (3) Ps. 23,963 million in lower costs of salaries, wages and social contributions. The following table sets forth the reconciliation of our production costs to our cost of sales for the years indicated: As of and for the Year Ended December 31, 2024 2023 (in millions of Ps.) Purchases and production expenses for the year 743,252.8 951,070.8 (+) Inventories at the beginning of the year 284,048.2 238,934.3 (-) Inventories at the end of the year 353,511.3 284,048.2 Cost of sales 673,789.8 905,956.9 The cost of sales of our segments is set forth below, eliminations between segments are not considered: •Cement, masonry cement and lime segment: Cost of sales from our cement, masonry cement and lime segment, without considering the eliminations between segments, decreased Ps. 193,887 million, or 25.5%, from Ps. 759,076 million in 2023 to Ps. 565,189 million in 2024. This decrease in cost of sales was mainly due to (1) lower thermal and electrical energy costs as a consequence of decreased sales volume and lower unitary costs in US dollars; (2) a decrease in salaries, wages and social contributions; and (3) lower freight costs mainly due to a decreased outbound and inbound transportation needs. •Concrete segment: Cost of sales from our concrete segment, without considering the eliminations between segments, decreased Ps. 37,534 million, or 32.7%, from Ps. 114,952 million in 2023 to Ps. 77,418 million in 2024. This decrease in the cost of sales was mainly due to a decrease in the cost of raw materials, salaries and social security contributions, maintenance costs and equipment leasing associated with the drop in volume. •Railroad segment: Cost of sales from our railroad segment decreased Ps. 12,824 million, or 13.1%, from Ps. 97,899 million in 2023 to Ps. 85,075 million in 2024, mainly due to lower transported volume coupled with lower costs of salaries, wages, social contributions and maintenance materials. •Aggregates segment: Cost of sales from our aggregates segment decreased Ps. 7,898 million, or 22.9%, from Ps. 34,510 million in 2023 to Ps. 26,612 million in 2024. This decrease was primarily due to lower equipment rental costs and lower salaries and social security contributions associated with the drop in volume. •Others segment: Cost of sales from Recycomb S.A.U. segment increased Ps. 587 million, or 11.5%, from Ps. 5,102 million in 2023 to Ps. 5,689 million in 2024. Gross profit Due to the factors mentioned above, our gross profit decreased Ps. 57,417 million, or 18.9%, from Ps. 303,388 million in 2023 to Ps. 245,971 million in 2024. Our gross margin (gross profit divided by revenues and expressed as a percentage) expanded by 166 basis points, from 25.1% in 2023 to 26.7% in 2024. Selling and administrative expenses Our selling and administrative expenses decreased Ps. 14,503 million, or 13.1%, from Ps. 110,764 million in 2023 to Ps. 96,261 million in 2024, mainly due to (1) a decrease in Taxes, duties, contributions, and commissions due to lower sales volume; (2) a decrease in Freight due to lower volume; (3) a decrease in salaries, wages and social contributions; and (4) a decrease in the remuneration of directors and trustees. Other gains and losses Our other gains and losses increases Ps. 3,362 million, or 127.9%, from a net gain of Ps. 2,630 million in 2023 to a net gain of Ps. 5,992 million in 2024, mainly due to the sale of property, plant and equipment. 95 Table of Contents Tax on bank accounts debits and credits Our tax on bank accounts debits and credits decreased Ps. 3,636 million, or 27.1%, from Ps. 13,397 million in 2023 to Ps. 9,761 million in 2024, related to the amount of monetary transactions carried out the respective fiscal year that trigger such tax. Financial results, net Our total net financial cost decreased Ps. 314,302 million, from a loss of Ps. 131,960 million in 2023 to a gain of Ps. 182,342 million in 2024, principally due to (1) a decrease of Ps. 278,273 million in loss due to exchange rate differences; (2) a decrease in gain on net monetary position of Ps. 51,685 million; (3) a lower charge of Ps. 101,143 million from interest on borrowings; (4) a lower profit of Ps 13,065 million from temporary investments; and (5) a higher loss from other net financial income and expense of Ps. 364 million. Our financial expenses decreased Ps. 101,489 million, or 48.3%, from Ps. 210,046 million in 2023 to Ps. 108,557 million in 2024, mainly due to a lower impact of Ps. 101,143 million from interest on borrowings Our financial income decreased Ps. 13,775 million, or 84.2%, from Ps. 16,357 million for 2023 to Ps. 2,582 million for 2024, mainly due to a lower amount of temporary investments. Income tax expense Our income tax expense increased Ps. 104,022 million, or 469.3%, from Ps. 22,166 million in 2023 to Ps. 126,188 million in 2024 mainly due to the increase in profit for the year 2024 compared to that of 2023. The resulting effective tax rate was 38.4% in 2024 compared to 44.4% in 2023, affected by the hyperinflation adjustments for income tax determination. The following table presents our effective tax rate reconciliation for each year. For the year ended December 31, 2024 2023 (amounts in millions of Ps.) Profit before income tax expense 328,282.3 49,897.2 Statutory rate 35 % 35 % Income tax at statutory rate (114,898.8) (17,464.0) Adjustments for calculation of the effective income tax: Recovery of tax losses 575.1 3,045.9 Effects of the inflation adjustment for accounting and tax purposes (11,715.3) (8,533.9) Other non-taxable income or non-deductible expense net (149.5) 786.1 Income tax expense (126,188.5) (22,165.9) Income tax expense Current (87,414.4) (10,914.1) Deferred (38,774.1) (11,251.8) Total (126,188.5) (22,165.9) Our current income tax increased Ps. 76,500 million, or 700.9%, from Ps. 10,914 million in 2023 to Ps. 87,414 million in 2024, mainly explained by a higher profit before taxes. Our deferred income tax increased Ps. 27,522 million, or 244.6%, from Ps. 11,252 million in 2023 to Ps. 38,774 million in 2024, mainly due to the use of tax loss carryforwards existing as of December 31, 2023. 96 Table of Contents Net profit As a result of the foregoing, our net profit increased Ps. 174,363 million, or 628.8%, from Ps. 27,731 million in 2023 to Ps. 202,094 million in 2024. Our net margin (net profit divided by revenues and expressed as a percentage) increased by 1,968 basis points, from 2.3% in 2023 to 22.0% in 2024. B.Liquidity and Capital Resources Our financial condition and liquidity is and will be influenced by a variety of factors, including: •our ability to generate cash flows from our operations; •the level of our outstanding indebtedness and the interest that we are obligated to pay on our indebtedness, which affect our net financial expenses; •variations in the exchange rate of Argentine pesos versus other currencies; •prevailing domestic and international interest rates, which affect our debt service requirements; and •our capital expenditure requirements, which consist primarily of investments in our operations, maintenance, equipment and plant facilities. Our principal cash requirements consist of the following: •working capital requirements; •the servicing of our indebtedness; and •capital expenditures related to investments in our operations, maintenance, equipment and plant facilities. During 2025, we used cash flow generated by our operations, primarily for capital expenditures, working capital needs and payment of interest on our financial debt. As of December 31, 2025, our cash and cash equivalents (defined as cash and banks and short-term investments as sated in Note 29 to our consolidated financial statements) was Ps. 31,416 million. On January 27, 2023, our board of directors approved the first issuance of simple corporate bonds not convertible into shares under our Global Corporate Bond Issuance Program for up to US$150.0 million which was approved by the general shareholders’ meeting held on April 16, 2020, the terms and conditions of which were approved by our board of directors at its meeting held on the same day. On February 22, 2023, the company issued its Class 1 Corporate Bonds, which resulted in a face value of Ps. 25,636.3 million (equivalent to US$133.3 million), bearing interest at BADLAR + 2% and maturing within 18 months.

The issue was approved by our board of directors on October 25, 2023. During the fiscal year ended December 31, 2025 and 2024, Loma Negra entered into funding agreements through stock market repurchase agreements (caución bursátil). These borrowings were obtained through Banco de Valores S.A. and were secured by public securities obtained on loan. The cost of these guarantees is included in the 97 Table of Contents borrowing rate and is accrued over the duration of the loan. The Group does not recognize assets or liabilities in connection with the collateral granted, as the associated guarantees do not transfer the rights or obligations of ownership. The Company also entered into fundraising agreements by issuing promissory notes through the EPYME channel of Caja de Valores S.A. On July 24, 2025, the Group issued its Class 5 Corporate Bonds in U.S. dollars for a total amount of US$ 112.9 million, with a fixed annual nominal interest rate of 8% payable semi-annually, and maturing on July 26, 2027. The corporate bonds were subscribed and integrated (i) in kind by delivering Class 2 and Class 3 corporate bonds for an amount of US$ 16.3 million and US$ 11.9 million, respectively, and (ii) in cash in U.S. dollars for a total amount of US$ 84.2 million. The exchange ratio for the Class 2 and Class 3 bonds was 100.91 and 103.10 of face value per 100 bonds tendered, respectively. In both cases, the exchange ratio includes accrued interest from the last interest payment date of the bonds to the date of issue and settlement, exclusive of all other amounts. As approved at the board of directors on January 7, 2026, on January 23, 2026, the Group issued Class 6 Corporate Bonds in U.S. dollars for a total amount of US$ 60,000,000, with a fixed annual nominal interest rate of 6.5% payable semi-annually, and maturing on January 23, 2029.

The exchange ratio of the Class 3 corporate notes was 103.37 of face value for every 100 delivered, respectively. The exchange ratio includes interest accrued from the last interest payment date of the corporate bonds to the issuance and settlement date, exclusive of all other amounts. Details of the outstanding borrowings as of December 2025 are included below. See "Item 5.B. Indebtedness and Financing Strategy." We believe that our cash and cash equivalents on hand, cash from operations and borrowings that we believe are available to us, will be adequate to meet our capital expenditure requirements and liquidity needs at least for the next 12 months. We implement liquidity risk management practices, keeping cash and other liquid instruments, as well as available funds. We may require additional capital to meet our long-term liquidity objectives and future growth requirements. The Group considers that it has adequate sources of liquidity, subject to the information outlined in "Item 3.D. Risk Factors" herein. Capital Resources After the completion of our capacity expansion project with the second line of L'Amalí in 2021, we significantly reduced our capital expenditures needs. During 2025, we principally invested in maintenance capital expenditures and the 25 kilograms project, which were financed mainly from our cash of operations and new debt financings. Regarding future commitments, we have no other material investment plans other than the ones related to maintenance capital expenditures.

The contract has been extended until 2027. We purchase various sources of energy from several suppliers, traders and distributors of natural gas. The relations with these suppliers ensure that we have the necessary levels of energy to operate and give us flexibility to purchase additional energy, if needed. None of these purchase orders represents a material amount of our total energy supply. In 2016, we entered into 20-year contract with Genneia S.A. and in 2018 we entered into a 20-year contract with Aluar Aluminio Argentino S.A.I.C., for the provision of wind-sourced electric power commencing on January 1, 2018 and in February 1, 2019, respectively, to ensure compliance with the obligations imposed by Law No. 26,190 and Law No. 27,191, and related regulations, whose main objective is to reduce the use of fossil energy by increasing the use of renewable energy for industrial users in Argentina commencing in 2018. In 2025, we entered into a 5-year contract with Luz de Tres Picos S.A. and Generación Eléctrica Argentina Renovable I S.A. SDE PEO, which will begin operating in September 2026. With these contracts, we currently exceed the requirements of the Law No. 27,191, reaching approximately 57% of renewable energy in the energy matrix. C.Research and Development, Patents and Licenses, etc. Intellectual Property As of December 31, 2025, Loma Negra had 121 registered trademarks, one of which is pending trademark application for renewal with the Argentine National Intellectual Property Institute ("INPI" (Instituto Nacional de la Propiedad Industrial)). In addition, Recycomb has two registrations and Ferrosur Roca has one registration and Fundación Loma Negra has two registrations. There are no pending trademarks of these companies. We do not own any registered patents, industrial models or designs. We are required to renew these trademark registrations when they expire at the end of their respective terms. Under the Argentine Trade and Service Marks Law No. 22,362, as amended, the term of duration of a registered trademark is 10 years from its issue date, and a trademark may be indefinitely renewed for equal periods thereafter if, within the five-year period prior to each expiration, the trademark was used in the marketing of a product, in the rendering of a service or as the designation of an activity. In addition, trademark holders must file a sworn declaration of use between the fifth and sixth year following registration, evidencing that the trademark has been used in connection with the relevant goods or services. Failure to comply with such requirement may result in the lapse of the registration. We have no pending litigation related to trademark matters. We have also registered our trademarks in Bolivia, Brazil, Chile, Paraguay and Uruguay. As of December 31, 2025, Loma Negra has 5 oppositions filed against third parties’ trademarks which are currently being resolved under the administrative opposition proceedings at INPI. In addition, Loma Negra is owner of 13 internet domains registered at the Network Information Center Argentina (NIC). We have no records of published works or deposits of unpublished works under copyright. 102 Table of Contents D.Trend Information We believe that the macroeconomic environment and the trends in the Argentine economy have affected and will, for the foreseeable future, continue to affect our results of operations and profitability. Our continued success and ability to increase our value to our shareholders will depend upon, among other factors, economic growth in Argentina. This analysis should be read in conjunction with “Item 5-A”— Operating Results — Principal factors Affecting Our Results of Operations.” In 2023, the Argentine economy faced notable challenges. A severe drought affected the agricultural sector leading to considerable export and tax revenue losses, consequently contributing to a federal budget deficit. These difficulties were exacerbated by the electoral developments within the year. The national consumer price index published by INDEC increased year-on-year by 211.4% in 2023 (as compared to 94.80% in 2022), 117.8% in 2024 and 31.5% in 2025. Additionally, the Argentine peso experienced a depreciation rate of 356.44% against the U.S. dollar in 2023, 27.7% in 2024 and 41.3% in 2025. Moreover, on April 1, 2025, the BCRA recorded a low level of U.S dollars reserves, amounting to US$25.45 billion. Despite a surge in reserves at the end of 2022 thanks to the strong contribution of the "soybean dollar" program for more than US$7,000 million, reserves have been constrained by the commercial commitments and debt payments that Argentina has to meet. Following a renegotiated agreement, the first disbursement of US$12 billion was made on 15 April 2025. This inflow brought Argentina’s international reserves to US$36,799 million. International reserves increased during 2025 and early 2026, primarily driven by financial support from international institutions and the appreciation of certain reserve assets (such as gold and currency revaluations). This growth was also supported by net foreign currency purchases by the BCRA in the professional exchange market and an increase in foreign currency deposits held by financial institutions at the BCRA. However, these inflows were partially offset by the BCRA’s intervention in the securities market to manage exchange rate volatility, interest and principal payments to international organizations (excluding the IMF), and the fulfillment of obligations under government securities, including the amortization of BOPREAL series. Furthermore, net outflows were recorded through the Local Currency Payment System (SML) and other regional settlement mechanisms.

Risk Factors—Risks Relating to Our Business and Industry.” Political changes and the initial policy actions taken by the current government to stabilize the macroeconomic landscape and curtail public expenditure led to a contraction in cement industry activity, with dispatches declining by 24% year-over-year in 2024. In 2025, cement dispatches have shown a moderate recovery, increasing by 5.6% year-over-year to reach 10.1 million tons, according to the Association of Portland Cement Manufacturers. The trajectory of the construction sector, and accordingly, our company's growth, is contingent upon the effectiveness of the Milei administration's efforts to normalize critical economic factors, curb inflation, and create an environment that fosters economic development. The realization of such conditions would likely foster a resumption in the growth of construction activity. E.Critical Accounting Estimates Not applicable.
