 balance. The facility, subsequently 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 (i) state-of-the-art hot strip mill (HSM) designed to roll advanced high strength steels (AHSS), Line Pipe & Stainless products, (ii) continuous pickling line (CPL) and coupled pickle line-tandem cold mll (PLTCM) optimized for auto production (including exposed) and (iii) 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). 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. The new steelmaking facility, integrated with ArcelorMittal’s HBI facility in Texas, will enable ArcelorMittal Calvert to supply automotive customers with lower CO 2 embodied steel, melted and poured in the United States. In accordance with the terms of the EPA, ArcelorMittal paid $1 consideration for the shares of NS Kote Inc., which holds 50% of the equity interest of AMNS
