How did ARBED become ArcelorMittal?

The evolution of ARBED into ArcelorMittal occurred through a series of strategic international mergers:

• Formation of Arcelor: In 2001, the Luxembourgian company ARBED SA merged with the Spanish firm Aceralia and the French company Usinor to create a new entity called Arcelor.12
• Creation of ArcelorMittal: In 2006, Mittal Steel initiated a hostile takeover bid for Arcelor. Despite initial resistance from the Luxembourgian government, the two companies eventually merged later that year to form ArcelorMittal, which became the world’s largest steelmaking company at the time of its formation.12

Headquartered in Luxembourg city, the company maintains its deep roots in the region's long history of steel production, which dates back to the 19th century and the exploitation of local iron ore deposits.12
