**Report on payments to governments for the year ended December 31, 2024**

This report provides a consolidated overview of the payments to governments made by Loma Negra Compañía Industrial Argentina Sociedad Anónima. ("Loma Negra," the "Company" or "us") for the fiscal year ended December 31, 2024.

All payments are reported in Argentine Pesos ("Ps."), the official currency of Argentina. All figures in Ps. are stated in the measuring unit current at the end of the reporting year (December 31, 2024) in accordance with the application of the method to restate financial statements in constant currency established by the International Accounting Standard 29, or IAS 29, as Argentina is considered a hyperinflationary economy. As of December 31, 2024, the official nominal exchange rate for pesos into U.S. dollars was Ps. 1,032.5000 per US$1.00 and as of September 19, 2025 the official nominal exchange rate for pesos into U.S. dollars was Ps. 1474.7500 per US$1.00.

**Our business segments**

We produce and distribute cement, masonry cement, lime, aggregates and concrete, which are products primarily used in private and public construction.

The principal raw materials used in the production of cement include: (1) limestone, clay and gypsum for the production of clinker, and (2) clinker additions, including blast furnace slag, pozzolana, fly ash, and paper bag, since we package a substantial portion of our cement in bags. We obtain nearly all of our mineral resources from our own quarries, using, either third party services or our own mining equipment. For the year ended December 31, 2024, all of our limestone was sourced from our own quarries. We own and exclusively operate our limestone quarries.

Our business segments are as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Cement, masonry cement and lime segment: this segment includes profit or loss from the cement, masonry cement and lime business, from procurement of raw materials in quarries, the manufacturing process of clinker and quicklime and their subsequent grinding with certain aggregates for the production of cement, masonry cement and lime.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Concrete segment: this segment includes profit or loss 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Railroad segment: this segment includes profit or loss from the provision of rail transportation services.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Aggregates segment: this segment includes profit or loss from the aggregates business, from extraction to crushing of stone.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Others segment: this segment includes profit or loss from the industrial waste treatment and recycling business for use as fuel.

**Our projects**

This report discloses the payments made by the Company to governments for the purpose of commercial development of minerals, such as limestone or granite, as part of our industrial cement and lime production and commercialization of aggregates.

As of December 31, 2024, we had four production stage mining properties. We have disclosed payments for the mining properties as separate projects segregated by product type and location:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• El Salitral y Cerro Bayo, a limestone quarry in Zapala, Province of Neuquen, Argentina. We consider this mining property as one project.
