Loma Negra Reports 2Q25 results Buenos Aires, August 7, 2025 – Loma Negra, (NYSE: LOMA; BYMA: LOMA), (“Loma Negra” or the “Company”), the leading cement producer in Argentina, today announced results for the three-month period ended June 30, 2025 (our “2Q25 Results”). 2Q25 Key Highlights  Net sales revenues stood at Ps. 174,511 million (US$ 149 million), and decreased by 8.0% YoY, mainly explained by a decrease of 9,9% in in the top line of the Cement segment.  Consolidated Adjusted EBITDA reached Ps. 37,005 million, decreasing by 30.6% YoY in pesos, while in dollars it reached 34 million, down 32.6% from 2Q24.  The Consolidated Adjusted EBITDA margin stood at 21.2%, decreasing by 691 basis points YoY from 28.1%.  Net Profit of Ps. 385 million, compared to a Net Profit of Ps. 41,246 million in the same period of the previous year, mainly due to a decrease in the net total finance results.  Net Debt stood at Ps. 256,186 million (US$215 million), representing a Net Debt/LTM Adjusted EBITDA ratio of 1.34x, compared to 0.89x in FY24. The Company has presented certain financial figures, Table 1b and Table 11, in U.S. dollars and Pesos without giving effect to IAS 29. The Company has prepared all other financial information herein by applying IAS 29. Commenting on the financial and operating performance for the second quarter of 2025, Sergio Faifman, Loma Negra’s Chief Executive Officer, noted: “The Argentine economy continues to recover, with INDEC reporting a 5.8% year- over-year GDP growth for the first quarter of the year. Cement dispatches in the industry also improved, maintaining the positive trend observed in previous quarters. Our own volumes grew 11% year-over-year during the quarter, and we expect this trend to continue, reaffirming our double-digit growth outlook for 2025. In terms of results, in this context of a still-incipient recovery for the sector, margins for the quarter stood at 21.2% on a consolidated basis, showing a year-over-year decline driven by the impact of a more challenging competitive dynamic, typical of a recovery phase that has yet to consolidate. Additionally, we are proud to announce the launch of our new 25-kilogram cement bag, reinforcing our commitment to the health and safety of construction workers, as well as our focus on innovation and the evolution of the industry. This important milestone required significant efforts and a US$70 million investment in industrial infrastructure aimed at adapting and upgrading our production processes. Finally, I would like to highlight the successful issuance in July of a US$112.9 million bond, which was very well received by investors. This transaction will allow us to meet upcoming Class 2 and other short-term maturities, while maintaining a healthy debt profile."

The recovery that began in the first months of the year maintained its momentum during the second quarter. Bulk cement dispatches started to show a stronger dynamic, driven by industrial and commercial projects as well as larger housing developments. Additionally, some provincial-level public works began to gain pace, although they remain at a very early stage. Bagged cement growth continued the trend seen in the first quarter, posting single-digit YoY growth. Concrete segment volumes increased by 44.0% year-over-year. Sales in the quarter were primarily driven by higher activity in private projects, mainly related to logistics infrastructure and residential developments. Additionally, there was an increased level of activity—although still in its early stages—in public works, mainly driven by road construction and infrastructure projects in the provinces of Buenos Aires and Santa Fe. Similarly, the aggregates segment grew by 34.1%, supported by sustained activity in road construction projects. Railway segment volumes grew by 10.6% compared to the same quarter in 2024, driven by increased transportation of construction materials, which offset the decline in grains, gypsum, and frac sand. These products were negatively affected by the disruption of the railway line connecting Bahía Blanca with Neuquén, caused by the storm that struck the area a few months ago.

Net Revenues Net revenue decreased 8.0% to Ps. 174,511 million in 2Q25, from Ps. 189,753 million in the comparable quarter last year, mainly due to the lower top line performance of the Cement business, followed by the rest of the main segments. The Cement, Masonry Cement, and Lime segment recorded a 9.9% year-over-year decline in revenues, despite an 11.1% increase in volumes that continued the recovery trend observed in previous quarters. Bulk cement dispatches performed more strongly, regaining ground from prior quarters, while bagged cement continued recovering at a steady pace. The positive impact of higher volumes was outweighed by softer pricing conditions, where, in the context of a still incipient recovery and a new low- inflation environment, the competitive landscape continues to limit pricing dynamic. Concrete revenue declined by 1.1% compared to 2Q24, mainly due to softer pricing dynamics in a highly competitive environment, despite a 44.0% increase in volumes. The growth in volumes was supported by private projects—mainly related to logistics infrastructure and residential developments—and a moderate uptick in public works. On the other hand, revenue in the Aggregates segment remained nearly flat, increasing by just 0.8% year-over-year. Sales volumes rose by 34.1%, driven by higher activity in road construction projects. However, this positive effect was offset by weaker pricing dynamics in a still-recovering competitive environment. Additionally, the sales mix had a negative impact, as road construction projects primarily require fine aggregates, which command a lower average price. Railroad revenues declined by 8.6% in 2Q25 compared to the same quarter of 2024, as higher transported volumes, up 10.6%, only partially offset softer pricing conditions. The disruption of the railway line in Bahía Blanca particularly affected longer-haul traffic (mainly grains, gypsum, frac sand), reducing ton-kilometers transported and, consequently, revenue generation. Cost of sales, and Gross profit Cost of sales remained virtually flat, rising by just 0.3% year-over-year to Ps. 138,917 million in 2Q25. Despite the increase in sales volumes, effective cost management and a lower depreciation impact helped offset potential cost pressures and contain overall expenses. In the Cement segment, lower maintenance costs and improved energy input prices positively impacted the quarterly performance. Continuing the trend from previous quarters, the Company continues to benefit from thermal energy contracts with year-over-year tariff reductions, including short-term agreements linked to oil production. On the electrical energy side, however, we are bearing the impact of adjustments in transmission and distribution costs, which have significantly increased electricity tariffs. Gross profit decreased by 30.5% in the second quarter, totaling Ps. 35,594 million compared to Ps. 51,215 million in 2Q24. Similarly, the gross profit margin contracted by 659 basis points year-over-year, reaching 20.4%. Selling and Administrative Expenses Selling and administrative expenses (SG&A) increased by 5.3%, totaling Ps. 18,676 million in 2Q25, compared to Ps. 17,742 million in 2Q24. This increase was mainly driven by higher salary and insurance costs, partially offset by lower marketing expenses. As a percentage of sales, SG&A reached 10.7%, rising by 135 basis points year-over-year.

Adjusted EBITDA decreased by 30.6% year-over-year in 2Q25, totaling Ps. 37,005 million, compared to Ps. 53,358 million in the same period of the previous year. This result was primarily driven by the weaker performance of the Cement business, followed by other segments, with the exception of the Railroad segment, which delivered a positive contribution. As a result, the Adjusted EBITDA margin contracted by 691 basis points, declining to 21.2% in 2Q25 from 28.1% in 2Q24. In particular, the Adjusted EBITDA margin of the Cement, Masonry, and Lime segment contracted by 678 basis points to 24.8%, as softer pricing performance was only partially offset by higher sales volumes and cost efficiencies, with costs declining by 11% on a per-ton basis. Meanwhile, the Concrete segment’s Adjusted EBITDA margin contracted by 773 basis points, down to -13.0%, compared to - 5.3% in 2Q24, as cost controls and improved volumes were not sufficient to offset the impact of a softer price dynamic. The Adjusted EBITDA margin of the Aggregates segment contracted to -27.3%, down from -10.8% in 2Q24. While volumes improved this quarter, a still challenging competitive environment and an unfavorable product mix weighed on the segment’s profitability. Regarding the Railroad segment, its Adjusted EBITDA margin expanded by 351 basis points to 9.8% in 2Q25, compared to 6.3% in 2Q24. Transported volumes improved, primarily driven by increased shipments of construction materials. However, the disruption of the railway line in Bahía Blanca particularly affected longer-haul traffic (mainly grains, gypsum, frac sand), reducing ton-kilometers transported and, consequently, revenue generation. These pressures were mitigated by cost reductions. Finance Costs-Net Table 5: Finance Gain (Cost), net (amounts expressed in millions of pesos, unless otherwise noted) Three-months ended June 30, Six-months ended June 30, 2025 2024 % Chg. 2025 2024 % Chg.

This significant year-over-year decline was mainly attributable to a lower gain on the net monetary position, as the inflationary effect on monetary liabilities moderated considerably compared to the same period last year, and to a higher impact from exchange rate differences resulting from the devaluation that followed the easing of capital controls. Meanwhile, Net Financial expense decreased by 58.5% year-over-year, to Ps. 9,787 million, reflecting the benefit of lower interest rates. Net Profit and Net Profit Attributable to Owners of the Company The Company reported a Net Profit of Ps. 0.4 billion in 2Q25, compared to Ps. 41.2 billion in the same period of the previous year. The decline was mainly driven by a lower financial result (net), reflecting a more moderate inflationary effect, coupled with lower operational performance. However, the decrease was partially offset by lower income tax expenses. Net Profit Attributable to Owners of the Company stood at Ps. 397 million. During the quarter, the Company reported a gain per common share of Ps. 0.6809 and an ADR gain of Ps. 3.4047, compared to a gain per common share of Ps. 70.7981 and a gain per ADR of Ps. 353.9903 in 2Q24.

Total debt at the close of the quarter stood at Ps. 272,081 million, composed by Ps. 270,713 million in short- term borrowings, including the current portion of long-term borrowings (or 99% of total borrowings), and Ps. 1,367 million in long-term borrowings (or 1% of total borrowings). At the close of the second quarter of 2025, 71% (or Ps. 192,363 million) of Loma Negra’s total debt was denominated in U.S. dollars, and 29% (or Ps. 79,717 million) was in Pesos. As of June 30, 2025, 21% of the Company's consolidated loans accrued interest at a variable rate, primarily based on the short- term market rate in pesos, as it is debt in local currency. The remaining 79% accrue interest at a fixed rate. By the end of the quarter, the average duration of Loma Negra’s total debt was 0.4 years. The Net Debt to Adjusted EBITDA (LTM) ratio stood at 1.34x as of the end of the second quarter, up from 0.89x as of December 31, 2024. After the close of the quarter, the Company issued its Class 5 corporate bond for US$112.9 million with a two-year tenor. The proceeds will be used to cancel the outstanding of Class 2 bond maturing in December, along with other short-term debt. With this issuance, the Company increased the average duration of its debt and maintains a well-balanced maturity profile.

This performance was primarily driven by a lower operational result and a higher income tax paid. The income tax paid during the quarter stood at Ps. 46,214 million and mainly corresponds to the amount determined for fiscal year 2024. Since the Company reported a negative result in 2023 for income tax purposes, no advance payments were made for 2024 until the final tax was assessed and became due in May 2025. Additionally, the Company has already started making advance payments for fiscal year 2025. This effect was partially offset by lower working capital needs in other areas. With the beginning of the winter season, we began to minimize clinker production and increase the use of inventories. During the quarter, the Company generated Ps. 45,605 million in cash from financing activities, mainly from new borrowings, net of repayments and interest payments. Additionally, Ps. 18,444 million were used in investing activities, primarily allocated to the 25-kilogram bagging project

The audio of the conference call will also be archived on the Company’s website at www.lomanegra.com Definitions Adjusted EBITDA is calculated as net profit plus financial interest, net plus income tax expense plus depreciation and amortization plus exchange rate differences plus other financial expenses, net plus tax on debits and credits to bank accounts, plus share of loss of associates, plus net Impairment of Property, plant and equipment, and less income from discontinued operation. Loma Negra believes that excluding tax on debits and credits to bank accounts from its calculation of Adjusted EBITDA is a better measure of operating performance when compared to other international players. Net Debt is calculated as borrowings less cash, cash equivalents and short-term investments.
