We announced a leadership transition that will help guide the company into its next chapter of growth. Effective January 1, 2027, Theresa E. Wagler will become President and Chief Executive Officer, succeeding Mark D. Millett as he transitions to Executive Chairman of the Board.
Mark's exceptional leadership and vision have helped shape Steel Dynamics into one of North America's leading metals solutions companies, and we're grateful for his continued service as Executive Chairman. We are equally excited for Theresa, whose nearly three decades of leadership, strategic insights, and dedication to our people and culture make her exceptionally well positioned to lead Steel Dynamics into the future.
Please join us in thanking Mark for his outstanding leadership and vision over the past three decades and congratulating Theresa, as we continue building on a strong foundation of innovation, growth, and value creation!
