Recent significant developments include the strategic acquisition by Ternium, which increased its stake in Usiminas to a controlling 51.5% during 2024, consolidating the company within the larger Latin American steel producer's portfolio. Usiminas reported robust operational performance with a 31% growth in EBITDA for its steel unit compared to 2023, alongside improvements in operational efficiency such as an 11% reduction in cost of goods sold and plans for sustained capital expenditure around BRL1 billion focused on plant modernization, fuel efficiency, and emissions reduction. Additionally, the company continued advancing its decarbonization efforts, including blast furnace refurbishments and emission reductions as part of its 2024 sustainability agenda. The mining unit MUSA remains operational with strategies to extend asset life to 2030 while maintaining cost control measures. These changes reflect Usiminas' focus on operational excellence, sustainability, and strategic integration under Ternium's control to strengthen its market position domestically and internationally.
