History and Development
ArcelorMittal was created in 2006 through the merger of Arcelor and Mittal Steel, forming the world’s largest steel producer at the time.
Before the merger, Mittal Steel—founded by Lakshmi Mittal—had already established a strong global presence, while Arcelor was a major European steel company with international operations. The combination of both groups significantly expanded production capacity and global reach.
Over time, the company expanded through acquisitions, operational restructuring, and investment in mining and steel production assets.
More recently, ArcelorMittal has focused on improving production efficiency and advancing sustainability initiatives, including projects aimed at reducing carbon emissions and modernizing steelmaking technologies.
The company continues to adapt its strategy to global demand cycles and changes in the steel industry.
