ArcelorMittal becomes sole owner of AM/NS Calvert plant

According to a statement from ArcelorMittal, the acquisition was completed under a definitive Equity Purchase Agreement (EPA) signed on October 11, 2024. As a result, ArcelorMittal has taken full ownership of the plant in Alabama, which is now called “ArcelorMittal Calvert”.

The plant was acquired by ArcelorMittal and NSC from ThyssenKrupp in 2014 for USD 1.55 billion. Established in 2010 with an investment of nearly USD 5 billion, the plant has an annual production capacity of 5.3 million metric tons of flat-rolled steel.

Considered one of the most advanced steel finishing facilities in North America, Calvert produces advanced high-strength steels, tubular products and stainless steel for the automotive and energy sectors. The facility includes a hot strip rolling mill, continuous pickling line, tandem cold rolling line, and galvanizing and annealing lines.

According to the statement, more than USD 2 billion has been invested in the plant since 2014. This included new crane systems, a logistics center, capacity increases in coating lines and a new steel production facility with a capacity to produce 1.5 million metric tons of low carbon steel per year. The first molten steel production was completed this month.

The new plant will be integrated with ArcelorMittal's HBI plant in Texas to support the supply of melted and cast low carbon steel in the US.

In addition, under a new agreement with NSC, local plate supplies will average 750,000 metric tons per year. ArcelorMittal continues to study the feasibility of further expanding steelmaking capacity at the plant.

In February 2025, the company announced its decision to invest USD 1.2 billion to build a non-grain oriented electrical steel (NOES) production facility in Calvert. The plant is scheduled to start production in 2027. The plant, which will have an annual production capacity of 150 thousand metric tons, is expected to serve the automotive, renewable energy and industrial sectors.

ArcelorMittal Chief Executive Officer (CEO) Aditya Mittal underlined the importance he attaches to the US steel industry and stated, "With full ownership of Calvert, we are further strengthening our presence in this market. I recognized the plant's growth potential during my first visit in 2014 and today we have a strategic asset capable of producing world-class low carbon steel."

John Brett, CEO of ArcelorMittal North America, stated that Calvert is an important element that increases the company's production power in the United States and added, “With a production approach that prioritizes safety, we will continue to contribute to the US steel industry with our new investments and local supply chain.”
