2025 CMC Sustainability Report

I am pleased to welcome you to our 2025 Sustainability Report. This report highlights CMC’s environmental, social and governance (ESG) achievements during the year and reinforces our drive to operate sustainably to support the long-term success of our business. CMC was founded as a recycling company over 110 years ago and we remain focused on ensuring that sustainability, along with our focus on people, excellence and growth, continue to be the pillars that drive our business strategy and operations.

The health and safety of CMC’s people continues to be our highest priority and I’m proud to report that we set another new record in 2025 for safety performance with our lowest ever recordable injury rate as well as no recordable injuries for the year at 133 facilities. This achievement is the result of our investments in creating a safety culture committed to continuous improvement and to the people that embody that culture.

CMC’s Transform, Advance, Grow (TAG) program was launched in 2024 to share best practices across all areas of our business including improving productivity and safety. TAG initiatives have enabled us to successfully identify opportunities to lower costs, reduce input consumption, optimize logistics and increase energy efficiency, which are also boosting our efforts to make CMC a more sustainable company.

We continued to invest in training and leadership development programs to empower our employees and develop future leaders who will power our growth and innovation. CMC continues to engage with local organizations to recruit talented people and provide career opportunities for people in our local communities. We support organizations that are dedicated to positively impacting our communities and contributed $1.7 million in 2025 through local and corporate giving campaigns.

This report details CMC’s programs focused on reducing our environmental impact and maintaining industry-leading environmental performance. While we remain focused on growth, we are committed to doing so in a way that helps address global challenges, including climate change. We support the circular economy through our vertically integrated operations, which include the entire lifecycle of steel, from production and fabrication to the collection and recycling of scrap to create new products. The pioneering technology we utilize to make steel, including what will soon be our most advanced new micro mill opening in 2026 in West Virginia, along with our continuous efforts to improve our operations, will enable CMC to achieve further reductions in greenhouse gas emissions and make progress toward our newly established environmental goals.

Our efforts continue to support our customers in meeting their sustainability goals. Environmental Product Declarations, or EPDs, are becoming an increasingly important tool to ensure our products meet green building standards and help reduce carbon emissions for construction projects. In 2025, we refreshed many of our EPDs and obtained several new EPDs for several of our products to ensure we are meeting our customer needs. Today, seven CMC products have EPDs.

Finally, our guiding principles include operating our business with the highest standards of integrity, strong governance structures and risk management programs to provide accountability and transparency to all our stakeholders. We remain committed to regular engagement with stakeholders through the communication of our strategies and our progress on meeting sustainability goals.

CMC’s employees around the world are the driving force behind our success, enabling us to meet the needs of our customers, partners, communities and shareholders. I want to thank them for their dedication and thank all our stakeholders for your continued support as we continue to improve the sustainability of our company. We remain optimistic about our ability to contribute positively to a sustainable future for all.
