The story
The Brazilian facilities of Aperam mostly correspond to Aperam South America (old Acesita), which was privatised by the Brazilian government in 1992 and purchased by Usinor in 1998.
Usinor merged with Arbed and Aceralia to become Arcelor in 2001, and Aperam became a wholly owned subsidiary of ArcelorMittal in 2007 in the hostile takeover of state-owned enterprise Arcelor by Lakshmi Mittal.
As of June 2021, 40.83% of Aperam is owned by the Lakshmi Mittal family.
Aperam completed the acquisition of Universal Stainless in January 2025.
Aperam finalized the acquisition of British company Magnatec Group in April 2026.
