About Mark Millett
Mark Millett, chairman and CEO of Steel Dynamics, has been discussing the company’s financial performance and strategic outlook during earnings calls from mid-2025 through early 2026. He reported record quarterly steel shipments of 3.6 million tons in the first quarter of 2026, with revenues of $4.8 billion and adjusted EBITDA of $664 million. Millett expressed confidence in the company’s through-cycle EBITDA projections of $650 to $700 million for its Sinton facility, plus an additional $40 to $50 million from its OmniSource recycling platform, and noted that capital spending for Sinton, value-add lines, and the aluminum venture is largely complete with a projected future through-cycle EBITDA contribution of over $1.4 billion. Millett has emphasized the company’s entry into aluminum production, stating that the first commercial-quality aluminum flat-rolled coils were shipped in June 2025. He described a significant domestic supply deficit of over 1.4 million tons of aluminum sheet, which he said is forecast to grow and is currently supplied by high-cost imports subject to tariffs that have increased from 10% to 50%. On trade policy, Millett stated his belief that tariffs will remain a mainstay of trade agreements and that the steel industry has undergone a paradigm shift supported by mercantilist policies. Regarding a joint offer with SGH for a potential acquisition, Millett said the offer was presented in February 2026, was “summarily rejected,” and that there has been no constructive engagement since. He also outlined a capital allocation strategy prioritizing business growth, a progressive dividend, and share repurchases, noting the company is selling at an “incredible discount.”
