- United States Steel Corporation (U.S. Steel) is an integrated steel producer that manufactures flat-rolled and tubular steel products; value-added steel sheet products including coated, galvanized and electrical steels; tin mill products; and iron ore pellets and coke, serving the automotive, appliance, container, construction, energy, industrial machinery and oil and gas industries. Headquartered in Pittsburgh, Pennsylvania, the company was founded in 1901 and operates major production facilities across the United States including Gary Works in Indiana, Mon Valley Works in Pennsylvania, Big River Steel Works in Arkansas, Granite City Works in Illinois and Fairfield Works in Alabama; it also maintains operations in Central Europe through U.S. Steel Košice in Slovakia. In June 2025, U.S. Steel completed its acquisition by Nippon Steel Corporation for approximately $14.9 billion under a U.S. government-approved National Security Agreement featuring a golden share that ensures the company remains U.S.-incorporated, retains its Pittsburgh headquarters and name, maintains a majority U.S. citizen board, and commits to $14 billion in domestic investments by 2028 including modernization of facilities such as the Gary Works hot strip mill, new slag recycling at Mon Valley Works, adoption of advanced lower-emission technologies, and enhanced product capabilities to drive operational savings and competitiveness. These investments support U.S. Steel's strategic shift toward sustainable steelmaking with expanded mini-mill capacity at Big River Steel, a LEED-certified facility, and a goal of net-zero carbon emissions by 2050 while honoring existing union contracts with the United Steelworkers. The ticker symbol USX1.DE reflects its listing on the German exchange following delisting from the New York Stock Exchange post-acquisition.
