ArcelorMittal completes the acquisition of Nippon Steel Corporation’s interest in AM/NS Calvert
18 June 2025, 19:30 CET
In accordance with the definitive Equity Purchase Agreement (the “EPA”) signed between ArcelorMittal (the “Company”) and Nippon Steel Corporation (“NSC”) on 11 October 2024, the Company confirms that it has completed the acquisition (the “transaction”) of NSC’s 50% equity stake in AM/NS Calvert, with ArcelorMittal already holding the balance.
The facility, now renamed ArcelorMittal Calvert, was originally acquired by ArcelorMittal and NSC in 2014 from ThyssenKrupp for total consideration of $1.55 billion. The operation was originally built at a cost of approximately $5 billion. It commenced operations in 2010 and has a flat rolled steel capacity of 5.3 million metric tonnes, annually. It is one of the most advanced steel finishing facilities in North America, with assets that include:
- State-of-the-art hot strip mill (HSM) designed to roll advanced high strength steels (AHSS), Line Pipe & Stainless products
- Continuous Pickling Line (CPL) and coupled Pickle Line-Tandem Cold Mill (PLTCM) optimized for auto production (including exposed)
- Coating and Continuous Annealing Lines, galvanized, galvanneal, aluminized, and cold rolled, which can supply advanced automotive grades including Gen3 AHSS and
Press Hardened Steel (PHS).
Since the acquisition in 2014, more than $2 billion in capex investments have been made to improve operational efficiency and enhance product offerings to the U.S. automotive and energy markets. Strategic investments include additional slab bays and cranes, a state-of-the-art logistics center to support high-volume pipe production and increased coil size, capability enhancements to the three coating lines and continuous annealing line, and the new state-of-the-art steelmaking facility with the capacity to produce 1.5 million metric tonnes of low CO2 steel, annually. The new steelmaking facility will be capable of supplying exposed automotive grades. Commissioning and first heat (an initial batch of molten steel marking the start of operations) were completed this month. In addition, a new seven-year domestic slab supply agreement with NSC has commenced, averaging 750,000 metric tonnes per year, ensuring a significant portion of the slab requirements are melted and poured in the United States. The feasibility of a steelmaking expansion at the site, which would further strengthen its U.S. domestic production capability, is being assessed.
