1. LEGAL INFORMATION Legal address: Loma Negra Compañía Industrial Argentina S.A. (hereinafter “Loma Negra”, “the Company” or “the Group”) is a corporation organized under the laws of the Argentine Republic with legal address in Boulevard Cecilia Grierson 355, 4th. Floor, City of Buenos Aires, Argentina. Fiscal year number: Fiscal year number 102, beginning January 1, 2026. Principal business of the Company: The Company and its subsidiaries, are referred to in these consolidated condensed interim financial statements as “the Group”. The main activity of the Group is the manufacturing and selling of cement and its derivatives, as well as the extraction of mineral resources that are used in the production process. At present, the Group has 8 cement factories in Argentina, in the provinces of Buenos Aires, Neuquén, San Juan and Catamarca. The Company also has mobile concrete plants that adapt to customer construction projects at all times. The Group, through its subsidiary Cofesur S.A.U., has a controlling interest in Ferrosur Roca S.A., a company whose capital is held by Cofesur S.A.U. with 80%, the National State with a 16% interest, and 4% has been transferred by the latter to the workers through a trust created for such purpose. Ferrosur Roca S.A. operates the railway cargo network of Ferrocarril Roca under a concession granted by the Argentine government in 1993 for a term of 30 years until March 2023, which allows access of several of Loma Negra’s cement production plants to the railway network. As a result of the National Government’s decision to put an end to the existing railway concession system in Argentina and shift to an open access model with the participation of private rail operators, the National Government decided not to grant extensions to the current concession contracts in the country. However, the Ministry of Transport published several resolutions precariously extending for periods between 12 and 18 months the concessions granted to various concessionaires, including Ferrosur Roca S.A. In July 2025, following a proposal from Nuevo Central Argentino S.A. to modify the terms of its concession contract, the Ministry of Economy granted Nuevo Central Argentino S.A. a formal extension of the concession until December 21, 2032. The resolution also instructed the Undersecretariat of Rail Transport to invite the remaining concessionaires, including Ferrosur Roca S.A. and Ferroexpreso Pampeano S.A., to submit similar contractual adjustment proposals, which could result in a longer-term formal renewal. Ferrosur submitted a letter outlining several relevant issues concerning the concession, which went unanswered by the administration. However, the current scheme of ten precarious and time-limited renewals, currently in effect until September 2025, was further extended by Resolution 52/2025 of the Secretariat of Transportation, extending the concession term of Ferrosur Roca S.A. until September 10, 2026, or an earlier date on which a new contracting model could be established. This resolution was challenged by Ferrosur through a motion for reconsideration, in which it alleged multiple breaches by the National Government and discriminatory treatment of Ferrosur. To date, the motion remains unresolved. Furthermore, the Undersecretariat of Transportation initiated the process to analyze, coordinate, and design a new contractual framework for the relationship between the National Government and the private sector for the operation of the current section of the National Railway Network under concession to Ferrosur Roca S.A. The Group has assessed potential business scenarios, based on its intention to continue providing railway services, and no significant impact is expected as of the issuance date of these consolidated financial statements (Note 30). The Group also has a controlling interest in Recycomb S.A.U., a company engaged in the treatment and recycling of industrial waste intended to be used as fuel or raw material.

- New standards New standards and interpretations are those issued during the three-month period ended March 31, 2026 and the standards and interpretations issued but not mandatory as of that date are described in Note 2.4 to the consolidated financial statements as of December 31, 2025. 3. CRITICAL ACCOUNTING JUDGMENTS AND KEY SOURCES USED FOR ESTIMATING UNCERTAINTY In the application of the Group´s accounting policies, the Group´s management is required to make judgments, estimates and assumptions about the carrying amounts of assets and liabilities that are not readily apparent from other sources. The estimates and associated assumptions are based on historical experience and other factors that are relevant. Actual results may differ from these estimates. In the ordinary course of its business, the Group selects tax criteria and accounting positions based on a reasonable interpretation of current regulations, also taking into account the opinion of its tax and legal advisors together with the evidence available up to the date of issue of these financial statements. However, there may be situations in which the assessment that a third party could make of them and the eventual realization of damage to the Group is uncertain. For such cases, the Group has evaluated the issues considering their significance in relation to the financial statements and has not made a provision as it is not required by current accounting standards. Underlying estimates and assumptions are continuously reviewed. Changes in estimates are accounted for prospectively. The unaudited consolidated condensed interim financial statements reflect all adjustments which are, in the opinion of Management, necessary to make a fair presentation of the results for the interim periods presented. There are no significant changes to the critical judgements used by Management in applying accounting policies to the critical judgements disclosed in the annual consolidated financial statements for the year ended December 31, 2025. 4.

The reconciliation of income tax expense for the three-month periods ended March 31, 2026 and 2025, and which would result from applying the statutory rate in force on the net profit before income tax expense that arises from the condensed interim statement of profit or loss and other comprehensive income for each period is as follows: LOMA NEGRA COMPAÑÍA INDUSTRIAL ARGENTINA SOCIEDAD ANÓNIMA NOTES TO THE UNAUDITED CONSOLIDATED CONDENSED INTERIM FINANCIAL STATEMENTS AS OF MARCH 31, 2026 (All amounts are expressed in thousands of Argentine pesos - $ - except otherwise indicated) Free translation in English of the original consolidated financial statements filed in Spanish with the Argentine National Securities Commission (“CNV”).

26. NON-CASH TRANSACTIONS Below is a detail of the transactions that did not involve cash flow movements during the three-month periods ended March 31, 2026 and 2025, respectively: 31.03.2026 31.03.2025 - Right of use of assets 239,431 213,421 - Acquisitions of property, plant and equipment financed with trade payables 168,082 2,673,039 27. SEGMENT INFORMATION The Group has adopted IFRS 8 – “Operating Segments”, that require operating segments to be identified on the basis of internal reports regarding components of the Group that are regularly reviewed by the Executive Committee, chief operating decision maker, in order to allocate resources to the segments and to assess their performance. This analysis is based on monthly information concerning historical figures of the identified segments. The information reviewed by the main decision maker basically consists in the historical details corresponding to each month accumulated until the end of the reporting period. It is for this reason that they differ from the inflation-adjusted figures as described in Note 2.2. For the purposes of managing its business both financially and operatively, the Group has classified the operations of its businesses as follows: i) Cement, masonry cement and lime: this segment includes the results from the cement, masonry cement and lime business, and comprises the procurement of raw materials from quarries, the manufacturing process of clinker / quicklime and their subsequent grinding with certain additions in order to obtain the cement, masonry cement and lime. ii) Concrete: this segment includes the results generated from the production and sale of ready-mix concrete. It also includes the delivery of the product at the worksite and, depending on the circumstances, the pumping of concrete up to the place of destination. iii) Aggregates: this segment includes the results generated from the production and sale of granitic aggregates. iv) Railroad: this segment includes the results generated from the provision of the railroad transportation service. v) Others: this segment includes the results of the industrial waste treatment and recycling business to produce materials for use as fuel.

28. FINANCIAL INSTRUMENTS 28.1. Net debt to equity ratio The net debt to equity ratio of the reported period/fiscal year is as follows: 31.03.2026 31.12.2025 Debt (i) 305,807,805 326,037,427 Cash and cash equivalents 46,400,550 34,382,022 Net debt 259,407,255 291,655,405 Equity (ii) 1,207,459,048 1,166,832,505 Net debt to equity ratio 0.21 0.25 (i) Debt is defined as current and non-current borrowings. (ii) Shareholders’ equity includes all the non-controlling interests, which are managed as capital. 28.2. Categories of financial instruments 31.03.2026 31.12.2025 Financial assets At amortized cost: Cash and banks 12,976,668 10,682,538 Investments 499,513 88,911 Accounts receivable and other receivables 103,086,399 100,879,017 At fair value through profit and loss: Investments 33,310,903 23,610,574 Financial liabilities Amortized cost 480,284,073 507,936,202 28.3. Financial risks The Group´s activities are exposed to a variety of financial risks: market risk (including foreign currency risk, interest rate risk and price risk considering the current inflation rates), credit risk and liquidity risk. The Group maintains an organizational structure and systems that allow the identification, measurement and control of the risks to which it is exposed. These consolidated condensed interim financial statements do not include all the information and disclosures on financial risks, therefore, they should be read in conjunction with the Group´s consolidated financial statements for the fiscal year ended December 31, 2025 issued on March 5, 2026. 28.4. Fair value measurement Fair value measurement is described in Note 32.8 to the annual consolidated financial statements as of December 31, 2025. From December 31, 2025 through March 31, 2026, there have been no significant changes in the industry’s economic activity affecting the fair value of the Group´s financial assets and liabilities, either measured at fair value or amortized LOMA NEGRA COMPAÑÍA INDUSTRIAL ARGENTINA SOCIEDAD ANÓNIMA NOTES TO THE UNAUDITED CONSOLIDATED CONDENSED INTERIM FINANCIAL STATEMENTS AS OF MARCH 31, 2026 (All amounts are expressed in thousands of Argentine pesos - $ - except otherwise indicated) Free translation in English of the original consolidated financial statements filed in Spanish with the Argentine National Securities Commission (“CNV”).

cost. In addition, there were no transfers among the different levels of fair value hierarchy to assess the fair value of the Group's financial instruments during the three-month period ended March 31, 2026. The carrying amounts of financial assets and liabilities recognized at amortized cost, included in the consolidated financial statement as of March 31, 2026 approximate to their fair values. Borrowings are measured at amortized cost considering the effective interest rate method, which approximate to their fair value given their cancellation period. 28.5. Exchange risk management The Group carries out transactions in foreign currency and is hence exposed to exchange rate fluctuations, also considering the current exchange regulations in force. Exposures in the exchange rate are managed within approved policy parameters using foreign exchange contracts. The carrying amounts of monetary assets and liabilities stated in currencies other than the functional currency of each company consolidated at the end of the reporting period/year are as follows: 31.03.2026 31.12.2025 Liabilities United States Dollars 284,435,657 298,606,787 Euro 2,136,957 1,894,017 Assets United States Dollars 36,483,825 9,270,509 Euro 15,109 18,060 Foreign currency sensitivity analysis The Group is mainly exposed to the US Dollar and Euro, considering that the Group’s functional currency is the Argentine peso. The following table shows the sensitivity of the Group to an increase in the exchange rate of the US dollar and the euro as of March 31, 2026. The sensitivity rate is the rate used when reporting exchange rate risk internally to key management staff and represents management’s assessment of a possible reasonable change in exchange rates. The sensitivity analysis includes only outstanding monetary items denominated in foreign currency and adjusts their translation on the balance sheet day for a 25% change in the exchange rate, considering for its calculation the whole of the items of the subsidiaries. Effect of US dollars Euro Loss for the period 61,987,958 530,462 Decrease in of shareholder's Equity 61,987,958 530,462 Additionally, considering the current exchange regulations existing in Argentina, the Group constantly monitors the alternatives for collecting assets and canceling liabilities in foreign currency and their corresponding impacts. The result derived from the use of financial instruments for the cancellation of operations in foreign currency is recognized at the moment in which the Group unconditionally commits or irreversibly executes such cancellation in kind. As of the date of issuance of these financial statements, the use of financial instruments to settle the aforementioned transactions would result in an impact of approximately 2.9% on the financial statements.

29. COMMITMENTS The Group’s commitments are described in Note 33 to the annual consolidated financial statements for the fiscal year ended December 31, 2025. 30. FERROSUR ROCA S.A. CONCESSION AND RELATED RAIL SERVICES Ferrosur Roca S.A. is indirectly controlled by the Company, through Cofesur S.A.U. which owns 80% of the interest, 16% of which belongs to the National State and the remaining 4% belongs to the workers of Ferrosur Roca S.A. through a trust created for this purpose. On March 11, 1993, Ferrosur Roca S.A. obtained the concession of the General Roca National Cargo Railway Network with the exception of the Altamirano-Miramar corridor and the urban sections, through the approval of the concession contract formalized by National Executive Branch Decree No. 2681/92, after the presentation made through a national and international tender and formalized to that effect. The area of influence is concentrated in the center and south of the province of Buenos Aires, north of the province of Río Negro and Neuquén. It has access to the ports of Buenos Aires, Dock Sud, La Plata, Quequén, and Bahía Blanca. On February 11, 2025, through Resolution 99/2025, the Ministry of Economy removed from the concession of Ferrosur Roca S.A. the station called Sola and the branch line that connects it from the bridge over the Riachuelo. The term of the concession was 30 years, expiring in March 2023, with the possibility of an extension of 10 additional years. Ferrosur Roca S.A. has renegotiated the Concession Agreement as a result of the renegotiation process for obligations arising from public administration contracts, including those for public works and services, in accordance with Law No. 25,561 and within the framework of ME Resolution No. 20/02 and Decree No. 293/02, subsequently repealed. The Contract Renegotiation Agreement signed between UNIREN (Contract Renegotiation and Analysis Unit) and Ferrosur Roca S.A. was ratified by the National Executive Branch through Decree No. 2017, dated November 25, 2008. On March 8, 2018, and with the due consent of Cofesur S.A.U., Ferrosur Roca S.A. requested the above-mentioned extension, and in line with the bidding terms and conditions and the concession agreement. The concession extension request was reiterated on March 1, 2019. However, as it is mentioned in following paragraphs, the federal government issued diverse regulations with the objective that the national railway network be based on a mixed modality combining public and private cargo operators, where the National State will manage the infrastructure and control the related investments, thus allowing any registered railway operator to provide railway services regardless of who owns or possesses the facilities at the point of loading or destination (the "open access" scheme). In line with this, on March 29, 2021, through Resolution No. 219/2021, the National Commission for the Regulation of Transport (“CNRT”) approved the Regulation of the National Registry of Railway Operators and granted said capacity to Ferrosur Roca S.A. and the other concessionaires that operate the current railway concessions. In accordance with said resolution, once the “open access” scheme is in force, any registered railway operator will be able to provide railway services, as previously mentioned. Subsequently, through Resolution No. 211 of the Ministry of Transport wich was published on June 28, 2021, rejected the request for an extension of the concession contract made by Ferrosur Roca S.A. in 2018, along with similar requests from other existing private railway concessionaires in the country, confirming the termination of all existing concession contracts with private freight railway concessionaires. Likewise, the Ministry of Transport published various resolutions extending for periods of between 12 and 18 months the concessions granted to the various concessionaires, including Ferrosur Roca S.A., by virtue of which the concession period has been extended for the a third time until September 10, 2026, or the earlier date on which a new contracting model could be established. In this regard, on May 16, 2025, the Ministry of Economy granted FEPSA a temporary extension of its concession until April 30, 2026. On July 22, 2025, it granted Nuevo Central Argentino S.A. an LOMA NEGRA COMPAÑÍA INDUSTRIAL ARGENTINA SOCIEDAD ANÓNIMA NOTES TO THE UNAUDITED CONSOLIDATED CONDENSED INTERIM FINANCIAL STATEMENTS AS OF MARCH 31, 2026 (All amounts are expressed in thousands of Argentine pesos - $ - except otherwise indicated) Free translation in English of the original consolidated financial statements filed in Spanish with the Argentine National Securities Commission (“CNV”).

extension of its concession until December 21, 2032, and instructed the Undersecretary of Rail Transportation to invite Ferrosur Roca S.A. to participate in the bidding process. and FEPSA to make a proposal for contractual adjustment in accordance with the terms of Law No. 27,132 and Decree 1027/2018 modified by Decree 478/2025. Ferrosur Roca S.A. submitted a note expressing various relevant issues of the Concession which was not answered by the administration. Notwithstanding the foregoing, on September 10, 2025, through Resolution 52/2025 of the Secretariat of Transportation, Ferrosur Roca S.A. was notified of the aforementioned extension, and the commencement of proceedings was established to analyze, coordinate, and design a new contractual framework for the relationship between the National Government and the private sector for the operation of the current concession, a process on which there are still no updates. This resolution was challenged by Ferrosur Roca S.A. through a motion for reconsideration, in which it alleged multiple breaches by the National Government and the existence of discriminatory treatment toward Ferrosur Roca S.A. To date, the motion remains unresolved. During the extended period, services will be provided on a provisional basis and may be revoked at any time without generating any subjective right, expectancy right, or precedent in favor of the operators, nor any recognition of any sum for the eventual early revocation of the concession. As of the date of issuance of these financial statements, there are no recorded acts by the National State aimed at generating a new contracting model for either FEPSA or Ferrosur Roca S.A. The following are some additional related general rules: • On July 8, 2024, Law 27,742, known as the “Framework Law,” was published in the Official Gazette, authorizing the National Executive Branch to tender new concessions, including those for the railway system. • Additionally, on June 13, 2024, through Decrees No. 525 and No. 526/2024, the Government declared a state of public emergency in the railway sector for a period of 24 months. This measure, announced through the Official Gazette, aims to "safeguard the operational security of the provision of freight and passenger rail transport services." No new regulations or rules related to the implementation of the aforementioned "open access" scheme have yet been issued. The measure authorizes the Ministry of Transport to carry out "transactional acts and/or compensations within the framework of the final settlement of the Concession Contracts approved by Decrees No. 1144 of June 14, 1991, No. 994 of June 18, 1992, No. 2681 of December 29, 1992, No. 2608 of December 22, 1993, and No. 430 of March 22, 1994, and those signed with the provinces within the framework of Decrees No. 532 of March 27, 1992, and No. 1168 of July 10, 1992.”). • Taking into account all of the above and its intention to continue providing rail services, the Company has reassessed its position. On February 10, 2025, Decree 67/2025 was published, authorizing the Ministry of Economy to proceed with the privatization of Belgrano Cargas y Logística Sociedad Anónima through vertical disintegration and the separation of the activities and assets of each business unit, under the modality of public auction for the sale of rolling stock, and through the execution of public works concession contracts for the tracks and their adjacent properties, and the use of the railway workshops. At present, no subsequent actions such as the publication of tender documents or the opening of bidding processes have been issued. The Group has re-evaluated all accounting estimates, taking into account available information affected by the end of the current concession, and no significant impact are expected to the date. As mentioned before, although the request for an extension has been rejected, the Company has been granted the status of a railway operator and could continue to provide its transport services under that figure or another that may be agreed upon once the concession period has ended, the Group's intention being to continue in the business, making the necessary changes to the business plan to reverse the current situation which is resulting in a deficit due to the alteration of the macroeconomic equation of the Concession Contract. The Group 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.

31. THE ARGENTINE CONTEXT Since the current National Government took office on December 10, 2023, it has implemented a series of structural reforms and economic measures aimed at macroeconomic stabilization. These include the approval of the so-called Framework Law, reforms aimed at modernizing the State and the labor system, the deregulation of strategic sectors, particularly the energy sector, and the implementation of an incentive program for large investments. Fiscal and monetary measures were also adopted to balance public accounts, including a restrictive monetary issuance scheme and modifications to the exchange rate regime to reduce distortions in the foreign exchange market. In this context, during the three-month period ending March 31, 2026, the Argentine economy continued its macroeconomic stabilization process, in an environment characterized by international financial volatility. According to data published by INDEC (National Institute of Statistics and Censuses), accumulated inflation in the first quarter of 2026 reached approximately 9.44%. Meanwhile, the official exchange rate of the Argentine peso against the US dollar registered a negative variation during the same period, with the local currency appreciating by approximately 6% when comparing the rates at the beginning and end of the quarter. At the close of the interim period, the performance of the main macroeconomic variables continued to be influenced by internal and external factors, including inflation, foreign exchange market behavior, international oil price fluctuations and their impact on local fuel prices, as well as the stability of the international financial environment. 32.
