SUSTAINABILITY

requirements and maintain a high certification rate for ISO 14001 standards at 100% of our steelmaking facilities. We also invest capital for environmental matters to maintain our social license to operate, with $66 million invested during 2025.

We continue to participate in various programs sponsored by the U.S. Department of Energy (“DOE”). In 2024, we announced that two of our investments were selected for up to $575 million in total award funding from the DOE. This awarded funding includes up to $500 million at our Middletown facility in Ohio, and up to $75 million at our Butler facility in Pennsylvania. The Middletown project involves investment in advanced, energy and GHG-efficient iron making to support continued production of high-quality, automotive-grade steel by Middletown. The Butler project involves replacing natural gas furnaces with electric induction furnaces for high-temperature reheating of grain oriented electrical steel. In 2025, we worked closely with DOE personnel to ensure alignment between the objectives of these steel mill investments and the goals of the new Presidential Administration.
