Results Conference Call 3Q26
1 Disclaimer and Forward-Looking Statement This presentation may contain forward-looking statements within the meaning of federal securities law that are subject to risks and uncertainties. These statements are only predictions based upon our current expectations and projections about possible or assumed future results of our business, financial condition, results of operations, liquidity, plans and objectives. In some cases, you can identify forward-looking statements by terminology such as “believe,” “may,” “estimate,” “continue,” “anticipate,” “intend,” “should,” “plan,” “expect,” “predict,” “potential,” “seek,” “forecast,” or the negative of these terms or other similar expressions. The forward-looking statements are based on the information currently available to us. There are important factors that could cause our actual results, level of activity, performance or achievements to differ materially from the results, level of activity, performance or achievements expressed or implied by the forward-looking statements, including, among others things: changes in general economic, political, governmental and business conditions globally and in Argentina, changes in inflation rates, fluctuations in the exchange rate of the peso, the level of construction generally, changes in cement demand and prices, changes in raw material and energy prices, changes in business strategy and various other factors. You should not rely upon forward-looking statements as predictions of future events. Although we believe in good faith that the expectations reflected in the forward-looking statements are reasonable, we cannot guarantee that future results, levels of activity, performance and events and circumstances reflected in the forward-looking statements will be achieved or will occur. Any or all of Loma Negra’s forward-looking statements in this release may turn out to be wrong. You should consider these forward-looking statements in light of other factors discussed under the heading “Risk Factors” in Company’s Annual Report on Form 20-F, as well as periodic filings made on Form 6-K, which are filed with or furnished to the United States Securities and Exchange Commission. Except as required by law, we undertake no obligation to update publicly any forward-looking statements for any reason after the date of this release to conform these statements to actual results or to changes in our expectations. The Company presented some figures converted from Argentine pesos to U.S. dollars for comparison purposes. The exchange rate used to convert Pesos to U.S. dollars was the reference exchange rate (Communication “A” 3500) reported by the Central Bank for U.S. dollars. The information presented in U.S. dollars is for the convenience of the reader only. Certain figures included in this report have been subject to rounding adjustments. Accordingly, figures shown as totals in certain tables may not be arithmetic aggregations of the figures presented in previous quarters. Note: Loma Negra’s financial information has been prepared in accordance with the Argentine Securities Commission (Comisión Nacional de Valores-CNV) and with International Financial Reporting Standards. Following the categorization of Argentina as a country with a three-year cumulative inflation rate greater than 100%, the country is considered highly inflationary in accordance with IFRS. Consequently, starting July 1, 2018, the Company is reporting results applying IFRS rule IAS 29. IAS 29 requires that results of operations in hyperinflationary economies are reported as if these economies were highly inflationary as of January 1, 2018, and thus year-to-date, together with comparable results, should be restated adjusting for the change in general purchasing power of the local currency, using official indices. For comparison purposes and a better understanding of our underlying performance, in addition to presenting ‘As Reported’ results, we are also disclosing selected figures as previously reported excluding rule IAS 29. Additional information in connection with the application of rule IAS 29 can be found in our earnings report.

Outlook
Outlook 2026 l Volumes during this quarter came in below initial expectations largely affected by weather conditions. l RIGI-approved projects together with other infrastructure projects, real wage recovery, and improved credit access could support volumes in the near future. l Top line was partially supported by favorable pricing dynamics amid lower volumes, while continued cost discipline helped protect profitability. l The issuance of a new US$ 150 million Bond in October reaffirmes our strong financial position and further improves our debt profile. 13
