ArcelorMittal has completed the acquisition of Nippon Steel Corporation’s 50pct stake in AM/NS Calvert, making it the sole owner of the advanced steel finishing facility, now renamed ArcelorMittal Calvert.
The deal, finalized under the Equity Purchase Agreement signed on October 11, 2024, was contingent on Nippon Steel completing its acquisition of U.S. Steel. ArcelorMittal already owned the remaining 50pct of the Alabama-based operation, originally purchased jointly with Nippon Steel from ThyssenKrupp in 2014 for USD 1.55 bln. The facility began operations in 2010 and has an annual flat-rolled steel capacity of 5.3 mln tons.
ArcelorMittal Calvert is one of North America’s most advanced steel finishing facilities, equipped with cutting-edge assets including a hot strip mill for advanced high-strength steels, line pipe and stainless steel production, multiple coating and annealing lines, and cold rolling capabilities optimized for automotive applications. It can produce a full range of automotive-grade steels, including Gen3 AHSS and press-hardened steel.
Additionally, in February 2025, ArcelorMittal announced a USD 1.2 bln investment to build a non-grain-oriented electrical steel (NOES) facility at the Calvert site. The plant will produce up to 150,000 tons of NOES annually, supporting sectors such as EVs, renewable energy, and industrial markets. The project is progressing on schedule, with major equipment orders placed, construction permits secured, and groundwork underway. First production is expected in 2027.
