TERNIUM TO INTEGRATE OPERATIONS IN THE USMCA

On February 14, 2023, Ternium's Board of Directors approved the construction of a new upstream production capacity project into the company’s existing downstream facility in Pesquería, Nuevo León, Mexico. The increased slab production capacity will complement and support the company’s new state-of-the-art hot rolling mill, which began operations in mid-2021, as well as the previously announced downstream project in Mexico. Ternium expects to invest approximately $2.4 billion toward the construction of an electric arc furnace (EAF)-based steel shop with annual capacity of 2.6 million tons, as well as a direct reduced iron (DRI) module with annual capacity of 2.1 million tons. The slab production capacity program will also include the construction of a port facility for raw material handling. Start of operations is anticipated to occur during the first half of 2026.
