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 101, beginning January 1, 2025. 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 received from Nuevo Central Argentino S.A. for changes to the terms of the concession contract, the Ministry of Economy resolved to grant the concession a formal extension until 2032. The aforementioned resolution also instructs the Subsecretary of Railway Transport to invite the remaining concessionaires, including Ferrosur Roca S.A., to submit a similar contractual adjustment proposal, which could result in a formal renewal with a longer term, replacing the current scheme of precarious and time-limited renewals currently in effect until September 2025. 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. Date of registration in the Argentine General Inspection of Justice (IGJ): - Registration of the bylaws: August 5th, 1926, under N° 38, Book 46. - Last amendment registered to the bylaws: September 26th, 2023, under N° 16,416, Book 114, of Companies by shares. - Correlative Number of Registration with the IGJ: 1,914,357. - Tax identification number [CUIT]: 30-50053085-1. - Date of expiration: July 3, 2116.

BASIS OF PREPARATION 2.1. Basis of preparation The accompanying consolidated condensed interim statement of financial position as of June 30, 2025, the consolidated condensed interim statement of profit or loss and other comprehensive income, consolidated condensed interim statement of changes in equity and of cash flows for the six month period ended June 30, 2025 and the notes to the consolidated condensed interim financial statements (hereinafter, the “interim financial statements”) are unaudited and have been prepared as interim financial information. These interim financial statements are prepared in accordance with International Accounting Standard (“IAS”) 34, Interim Financial Reporting, pursuant to the provisions in Technical Resolution No. 26 (as amended) issued by the Argentine Federation of Professional Councils of Economic Sciences [FACPCE] and the Regulations issued by the Argentine Securities Commission [“Comisión Nacional de Valores” (CNV)]. Consequently, not all of the disclosures required in accordance with International Financial Reporting Standards (“IFRS”) for annual financial statements are included herein, hence, these consolidated condensed interim financial statements shall be read in conjunction with the Group’s consolidated financial statements for the fiscal year ended December 31, 2024 issued on March 6, 2025. In the opinion of the Group’s Management, these unaudited consolidated condensed interim financial statements include all normal recurring adjustments, which are necessary for a fair representation of financial results for the interim periods presented. The financial information as of December 31, 2024 presented in these unaudited consolidated condensed interim financial statements arises from our audited consolidated financial statements for the fiscal year ended December 31, 2024, restated in closing currency of the reported period, following the guidelines in IAS 29. Such guidelines have been described in Note 2.2 to our consolidated financial statements as of December 31, 2024. The results of operations for the six-month period ended June 30, 2025 do not necessarily reflect the results for the full year. The Company believes that the disclosures are appropriate and adequate to consider that the information presented is not misleading. These consolidated condensed interim financial statements were approved for issue by the Board of Directors on May 6, 2025, the date when the interim financial statements were available for issuance. As a consequence of the activities in which the Group is engaged, its transactions do not have a significant cyclical or seasonal character. Nevertheless, during the second half of the year, the volume of sales in Argentina has historically showed a slight increase. 2.2. Basis of consolidation These interim financial statements include the unaudited consolidated condensed interim statement of financial position, results of operations and cash flows of the Company and its consolidated subsidiaries. The basis of consolidation and the subsidiaries are the same as for the Company’s audited consolidated financial statements for the year ended December 31, 2024.

Application of new and revised International Financial Reporting Standards (IFRS) - Adoption of new and revised IFRS The Group has adopted all of the new and revised standards and interpretations issued by the International Accounting Standards Board (“IASB”) that are relevant to its operations and that are mandatorily effective as of June 30, 2025, as described in Note 2.4 to the Group's annual consolidated financial statements as of December 31, 2024. The Group has not opted for early adoption of any other standard, interpretation or amendment that has been issued but is not yet in force. - New standards New standards and interpretations are those issued during the six-month period ended June 30, 2025 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, 2024. 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, 2024.

26. NON-CASH TRANSACTIONS Below is a detail of the transactions that did not involve cash flow movements during the six-month periods ended June 30, 2025 and 2024, respectively: 30.06.2025 30.06.2024 - Right of use of assets 316,637 99,105 - Acquisitions of property, plant and equipment financed with trade payables 836,504 485,525 - Share-based payment plans - benefit plan – 717,330 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: 30.06.2025 31.12.2024 Debt (i) 272,080,526 196,702,077 Cash and cash equivalents 15,894,322 9,844,659 Net debt 256,186,204 186,857,418 Equity (ii) 935,771,281 912,858,950 Net debt to equity ratio 0.27 0.20 (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 30.06.2025 31.12.2024 Financial assets At amortized cost: Cash and banks 10,060,042 9,178,863 Investments 61,071 73,690 Accounts receivable and other receivables 74,548,221 68,122,632 At fair value through profit and loss: Investments 5,773,209 592,106 Financial liabilities Amortized cost 392,988,323 386,666,436 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, 2024 issued on March 6, 2025. 28.4. Fair value measurement Fair value measurement is described in Note 32.8 to the annual consolidated financial statements as of December 31, 2024.

From December 31, 2024 through June 30, 2025, 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 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 six-month period ended June 30, 2025. The carrying amounts of financial assets and liabilities recognized at amortized cost, included in the consolidated financial statement as of June 30, 2025 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: 30.06.2025 31.12.2024 Liabilities United States Dollars 215,402,994 204,991,553 Euro 5,684,380 1,517,621 Real 564 487 Assets United States Dollars 13,732,136 11,476,235 Euro 14,142 12,666 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 June 30, 2025. 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 50,417,715 1,417,560 Decrease in of shareholder's Equity 50,417,715 1,417,560 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 June 30, LOMA NEGRA COMPAÑÍA INDUSTRIAL ARGENTINA SOCIEDAD ANÓNIMA NOTES TO THE UNAUDITED CONSOLIDATED CONDENSED INTERIM FINANCIAL STATEMENTS AS OF JUNE 30, 2025 (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”).

COMMITMENTS The Group’s commitments are described in Note 33 to the annual consolidated financial statements for the fiscal year ended December 31, 2024. 30. FERROSUR ROCA S.A. CONCESSION AND RELATED RAIL SERVICES 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. 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. 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. requested the above-mentioned extension in due time on March 8, 2018, 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 the Company 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 second time until September 2025. Those resolutions provide that during the extended concession period the services will be delivered on a provisional basis and may be revoked at any time without this generating any subjective right, pending right or setting any precedent that may be claimed in favor of the operators, or otherwise the recognition of any amount for the potential early revocation of the additional concession term granted.

On July 8, 2024, Law 27,742, known as the “Bases Law”, was published in the Official Gazette, which enables the National Executive Branch to tender new concessions, including the railway system. Additionally, on June 13, 2024, through Decrees 525 and 526/2024, the Government declared a public emergency in railway matters for a period of 24 months. This measure, announced through the Official Gazette, aims to "protect the operational security of the provision of freight and passenger railway transport services", with no new regulations or rules related to the implementation of the aforementioned "open access" scheme having yet been issued and authorized the Ministry of Transportation to carry out "transactional acts and/or compensations within the framework of the final liquidation of the Concession Contracts approved by Decrees Nos. 1144 of June 14, 1991, 994 of June 18, 1992, 2681 of December 29, 1992, 2608 of December 22, 1993 and 430 of March 22, 1994 and those signed with the provinces within the framework of Decrees Nos. 532 of March 27, 1992 and 1168 of July 10, 1992.” On May 16, 2025, the Ministry of Economy, through Resolution 651/2025, granted FEPSA a temporary extension of its concession until April 30, 2026. Meanwhile, on July 22, 2025, resolution RESOL-2025-39-APN-ST#MEC of the Ministry of Economy was published in the Official Gazette, repealing Resolution 211/2021 of the same ministry and granting Nuevo Central Argentino S.A. an extension of the concession until December 21, 2032. The aforementioned Resolution instructs the Subsecretary of Railway Transport to invite Ferrosur Roca S.A. and FEPSA to make a proposal for contractual adjustment in accordance with Law No. 27,132 and Decree 1027/2018, as amended by Decree 478/2025. Taking into account all of the aforementioned and its intention to continue providing rail services, the Group has re- evaluated all accounting estimates affected by the end of the current concession, and no significant impact are expected to the date. 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. The Group’s Management understands that the intention of the National State is to prioritize the continuity of the current operators for each of the existing services and businesses, thus guaranteeing the best use of the experience they have acquired. 31. COMPLAINTS BROUGHT AGAINST THE GROUP AND OTHERS IN THE UNITED STATES During 2018, two lawsuits were brought in the United States (“USA”) against the Group, its directors and some of its first-line managers and the controlling shareholder at the time of the Company’s initial public offering in 2017 (“Initial Public Offering” or “IPO”), one in federal court and the other in the state of New York. Regarding the lawsuit filed in federal jurisdiction, during 2020, the Court sustained the motion to dismiss filed by the Group. Finally, on July 21, 2020, the plaintiffs voluntarily withdrew the appeal filed against the judgment of first instance that fully sustained the motion to dismiss submitted by the Group. Accordingly, a final and conclusive judgment was rendered in favor of the Group and the rest of the defendants, and the lawsuit came to an end. Regarding the state class action (Kohl v. Loma Negra CIASA, et al. -Index No. 653114/2018 - Supreme Court of the State of New York, County of New York), on October 11, 2023, we entered into a proposed agreement with the lead plaintiff. The Agreement does not contain any admission or acknowledgment of guilt for wrongful conduct by Loma Negra or other defendants in the class action, and it includes a release of all claims. The New York State Court issued a final judgment under the Settlement on March 3, 2025. The deadline to appeal the judgment expired on April 2, 2025 and no appeal was filed. As a result, the settlement is now completely final and the releases are effective. 32. THE ARGENTINE CONTEXT During 2024, the federal government promoted several bills and succeeded in approving some key regulations for Argentina's economic activity. The main initiatives include the approval of the Law for the Bases and Starting Points for Argentines' Freedom No. 27,742 (“Bases Law”), which includes the declaration of a public emergency granting the Federal Executive delegated powers in several areas; the reform of the State, which will allow the government to sell some government-owned companies; the modernization of labor regulations to encourage the growth of formal private LOMA NEGRA COMPAÑÍA INDUSTRIAL ARGENTINA SOCIEDAD ANÓNIMA NOTES TO THE UNAUDITED CONSOLIDATED CONDENSED INTERIM FINANCIAL STATEMENTS AS OF JUNE 30, 2025 (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”).

employment; the deregulation of the energy sector, aimed at maximizing the oil & gas production in the country for sale and export purposes; and an incentive system for large investments, applicable to energy, oil, gas and infrastructure projects. The federal government also approved a fiscal package that includes an tax amnesty program and a regularization system for assets, allowing for the legalization of money and goods. These measures seek to achieve fiscal balance, with a zero monetary emission policy, and it has enabled the government to achieve in a short term a primary and financial surplus, as well as to begin an inflation deceleration process. Growth projections are projected at 5% this year, supported by a recovery in consumption and increased investment, although uneven across sectors. Following agreements with the IMF, Argentina has agreed to receive USD 23.1 billion in unrestricted funds during 2025. To date, US$12 billion of this amount has been received, with the aim of strengthening the Central Bank through the exchange of Non-Transferable Bills and addressing potential exchange rate pressures. Simultaneously with the announcement of this agreement, the government modified the exchange rate system as of April 14, 2025, eliminating most of the existing restrictions on access to the MULC (Single and Free Exchange Market) for companies and all individuals. These actions reflect the government's commitment to stabilizing the economy, promoting investment, and improving the country's fiscal situation in a context of economic challenges. 33.
