- Loma Negra Compañía Industrial Argentina Sociedad Anónima, Argentina's leading vertically integrated producer and distributor of cement, masonry cement, lime, aggregates, ready-mix concrete and other construction materials, operates through its Cement, Masonry Cement and Lime; Concrete; Rail Services; Aggregates; and Others segments. The company manufactures Portland cement, masonry cement, lime, granitic aggregates, ready-mix concrete and precast concrete products under brands including Loma Negra, San Martín, Plasticor, Cacique Plus, Cacique Max, Loma Negra Plus and Lomax; it supplies wholesale distributors, concrete producers, industrial customers and contractors for private and public construction, infrastructure projects and industrial applications. Founded in 1926 by Alfredo Fortabat and headquartered in Buenos Aires, Loma Negra maintains production facilities, quarries and a distribution network across Argentina, including key plants in Olavarría, with rail transportation services supporting logistics; it operates as a subsidiary of InterCement Trading e Inversiones Argentina Sociedad Limitada, part of the Brazilian InterCement group.
In recent developments, InterCement, the controlling shareholder holding approximately 52 percent of shares, enters advanced negotiations for the sale of its stake in 2025 as part of a broader liability restructuring, with exclusivity periods extended multiple times through December 2025 to Argentine investor groups led by Marcelo Mindlin and previously Companhia Siderúrgica Nacional (CSN), marking a potential return to Argentine ownership after over 20 years under Brazilian control. The company reports operational expansions including increased renewable energy usage to 61 percent of its energy mix, capacity upgrades at plants and product diversification to support rising infrastructure demand in roads, public buildings and real estate; it sustains a near 45 percent market share amid sales challenges in 2025 influenced by political uncertainty and elections.
