On a sequential basis, the margin also improved, with a significant increase of 552 basis points. ▪ Net Profit of Ps. 29,584 million, up 225.9% from Ps. 9,076 million in the same period of the previous year, mainly due to the solid operational results despite a volume decrease and the improvement in the net total finance gain. ▪ Net Debt stood at Ps. 197,915 million (US$ 217 million), representing a Net Debt/LTM Adjusted EBITDA ratio of 1.26x compared with 1.40x in FY23. 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 2024, Sergio Faifman, Loma Negra’s Chief Executive Officer, noted: “We are glad to report another set of solid results. Despite the year-on-year volume decline our business delivered an expansion of the Adjusted EBITDA margin that demonstrates our strong capability for efficiency and flexibility in adapting to challenging scenarios and our constant focus on profitability. As the stabilization program implemented by the Milei administration begins to show positive results in reducing inflation and consolidating a fiscal surplus, construction activity is beginning to show signs of recovery. Cement volumes have been displaying a positive trend of continuous sequential growth since reaching a low in March. Although economic challenges remain, we believe that we are in a transition period. As macroeconomic variables stabilize and the economic environment improves, we expect to see a much stronger recovery. Meanwhile, our focus is on efficiency and cost control while maintaining our leadership position and commitment to our clients and suppliers. In this regard, in the second quarter, we delivered an Adjusted EBITDA of US$51 million, achieving an impressive EBITDA per ton of US$45, posting an improvement of 23% year-on-year and 16% on a sequential basis. We are optimistic that this positive trend in the industry will consolidate, as July's dispatch figures already show significant improvement. Therefore, we have strong indications to expect further recovery in the second half of the year.”

Overview of Operations Sales Volumes Table 2: Sales Volumes2 Three-months ended June 30, Six-months ended June 30, 2024 2023 % Chg. 2024 2023 % Chg. Cement, masonry & lime MM Tn 1.09 1.61 -32.5% 2.15 3.15 -31.9% Concrete MM m3 0.09 0.17 -45.2% 0.17 0.31 -45.1% Railroad MM Tn 0.83 1.07 -22.5% 1.53 2.04 -25.2% Aggregates MM Tn 0.22 0.30 -24.9% 0.44 0.65 -32.4% 2 Sales volumes include inter-segment sales Sales volumes of Cement, masonry, and lime during 2Q24 decreased by 32.5% to 1.1 million tons, although cement volumes have shown a gradual recovery since March. In this regard, we must consider that although June dispatches showed a sequential decrease in volumes, this was due to the effect of fewer working days. The average daily dispatches, however, indicate growth figures on a sequential basis. This recovery is more evident in bagged cement sales, as the bulk mode remains more affected by macroeconomic conditions and the low presence of public works and large private works. Regarding of the volume of the Concrete segment, there was a decrease of 45.2% year-over-year. Segment volumes followed the trend of bulk cement dispatches, as concrete producers remained among the most affected due to lower activity levels in their target construction projects. Public sector works are still almost halted, although some projects transferred from the national government to the provincial governments are starting to resume activities. Similarly, volumes for the Aggregates segment declined year-over-year but at a slower pace, decreasing by 24.9% The Railway segment experienced a contraction of 22.5% compared to the same quarter of 2023. The lower transported volume of construction materials and chemicals was partially offset by an improvement in grains and fracsand.

The Cement, masonry cement, and lime segment was down 26.1% YoY, with volumes contracting by 32.5%. Even though lower demand affected both modes of dispatches, bulk cement was more impacted by the economic environment, the standstill of public works a lower level of activity in larger private works. However, this effect was partially offset by a positive price dynamic.

Concrete registered a decrease in its revenue of 47.1% compared to 2Q23. This was mainly due to lower volumes, which decreased by 45.2%. Similarly, the Aggregates segment posted a decrease in revenue of 35.6%, with sales volumes dropping 24.9%. Railroad revenues showed a more moderate decrease of 14.5% in 2Q24 compared to the same quarter of 2023, primarily due to a lower transported volume, which decreased by 22.5% in the quarter, mainly affected by the decrease in transported volumes of construction materials and chemicals, partially offset by an increase in fracsand and grains. The positive price dynamic partially offset this effect, boosted by an increase in the average transported distance. Cost of sales, and Gross profit Cost of sales decreased by 31.1% YoY, reaching Ps. 99,367 million in 2Q24, mainly due to the decrease in sales volumes across all segments, a lower impact of depreciations and tight cost control. Regarding the cost of sales for Cement, the clinker used during the quarter was primarily produced during the warmer months, when energy inputs were lower. Most of the kilns were turned off during the quarter to avoid higher energy costs and a potential shortage of natural gas. The Company will mostly use its clinker stock until spring, when the kilns operation will be resumed. Regarding electrical energy, the company reduced its energy needs due to the halt in the limestone grinding phase of the cement production process, increasing the relative weight of renewable energy in the matrix to 64%, up from 36% in 2Q23, which also resulted in a reduction in energy costs. Additionally, there were also reductions in salaries and freight costs, as well as lower depreciation compared to 2Q23. Gross Profit decreased 18.1% YoY to Ps. 36,735 million in 2Q24, from Ps. 44,834 million in 2Q23, with a gross profit margin expansion of 329 basis points YoY to 27.0%. Selling and Administrative Expenses Selling and administrative expenses (SG&A) decreased 28.5% to Ps. 12,726 million in 2Q24, from Ps. 17,807 million in 2Q23. This was mainly due to lower salaries, a reduction in insurance costs and a decrease in turnover tax and freight costs related to lower volume. As a percentage of sales, SG&A remained flat at 9.4%, despite the decrease in the top line.

Likewise, the Adjusted EBITDA margin expanded 520 basis points to 28.1% compared to 22.9% in 2Q23. On a sequential basis, the margin also showed a significant improvement, up 552 basis points. In particular, the Adjusted EBITDA margin of the Cement, Masonry and Lime segment expanded 565 bps to 31.5%. The positive price performance, coupled with lower energy inputs and a decrease in SG&A, boosted the margin recovery deflecting the drop in volumes. Concrete Adjusted EBITDA margin contracted 796 bps, and stood at negative 5.3%, from 2.7% in 2Q23. The low level of activity in the segment took a toll on segments’ profitability. The Adjusted EBITDA margin of Aggregates contracted to negative 10.8%, from 5.3% in 2Q23, mainly due to lower dilution of fixed costs resulting from decreased volumes, coupled with a softer price performance affected by product mix.

Finally, the Adjusted EBITDA margin of the Railroad segment improved 553 bps to 6.3% in the second quarter, from negative 0.8% in 2Q23. Despite the decrease in transported volumes, the positive price performance boosted by the increase in the average transported distance, and a better result in SG&A and Other gains that deflected the cost increase.

Net Profit and Net Profit Attributable to Owners of the Company Net Profit of Ps. 29.6 billion in 2Q24 compared to a net profit of Ps. 9.1 billion in the same period of the previous year. The solid operational result, despite the drop in volumes, along with a higher total financial gain, explain the improved outcome. On the financial side, the positive effect of inflation on the net monetary position is the main reason for the variation, combined with a smaller impact from exchange rate differences and lower net financial costs. This gain was partially offset by higher income tax expenses. Net Profit Attributable to Owners of the Company stood at Ps. 29.6 billion. During the quarter, the Company reported a gain per common share of Ps. 50.7804 and an ADR gain of Ps. 253.9018, compared to a gain per common share of Ps. 16.2010 and a gain per ADR of Ps. 81.0052 in 2Q23. Capitalization Table 6: Capitalization and Debt Ratio (amounts expressed in millions of pesos, unless otherwise noted) As of June 30, As of December, 31 2024 2023 2023 Total Debt 200,995 266,548 264,932 - Short-Term Debt 76,367 85,252 66,920 - Long-Term Debt 124,628 181,296 198,012 Cash, Cash Equivalents and Investments (3,080) (89,512) (12,106) Total Net Debt 197,915 177,036 252,825 Shareholder's Equity 618,353 544,095 528,930 Capitalization 819,348 810,643 793,861 LTM Adjusted EBITDA 157,189 215,312 180,404 Net Debt /LTM Adjusted EBITDA 1.26x 0.82x 1.40x As of June 30, 2024, total Cash, Cash Equivalents, and Investments were Ps. 3,080 million compared with Ps. 89,512 million as of June 30, 2023. Total debt at the close of the quarter stood at Ps. 200,995 million, composed by Ps. 76,367 million in short- term borrowings, including the current portion of long-term borrowings (or 38% of total borrowings), and Ps. 124,628 million in long-term borrowings (or 62% of total borrowings). At the close of the second quarter of 2024, 63% (or Ps. 125,969 million) of Loma Negra’s total debt was denominated in U.S. dollars, and 37% (or Ps. 75,026 million) was in Pesos.

As of June 30, 2024, 34% of the Company's consolidated loans accrued interest at a variable rate, primarily based on BADLAR, as it is debt in pesos. The remaining 66% accrues interest at a fixed rate in foreign currency. By the end of the quarter, the average duration of Loma Negra’s total debt was 1.0 years. The Net Debt to Adjusted EBITDA (LTM) ratio stood at 1.26x as of June 30, 2024, down from 1.40x as of December 31, 2023. The Company's debt maturity profile remains comfortable, with no foreign-denominated debt maturing this year. This year, the Company only needs to address the maturity of the Class 1 bond (issued in Ps.) and the revolving short-term debt. The second half of the year requires less capital due to the utilization of stocks during the winter, so the Company will meet the short-term debt obligations with its cash generation, bank credit lines or other short-term instruments.

In the upcoming quarters this effect will be reversed, as the clinker inventories will mostly be used during the winter season when most of the kilns will remain shut down. During 2Q24, the Company used cash in financing activities for Ps. 2,118 million, mainly for interest payments and proceeds from borrowings net of repayment. Regarding cash used in investing activities, the Company spent a total of Ps. 16,646 million, primarily on maintenance capex and the 25-kilogram bags 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.
