ArcelorMittal was created by the takeover of Western European steel maker Arcelor (Spain, France, and Luxembourg) by Indian-owned multinational steel maker Mittal Steel in 2006, at a cost of €40.37 per share, approximately $33 billion total. Mittal Steel launched a hostile takeover bid which replaced a previous planned merger between Arcelor and Severstal, which had lacked sufficient shareholder approval. The resulting merged business was named ArcelorMittal and is headquartered in Luxembourg.
The resulting firm produced approximately 10% of the world's steel, and was by far the world's largest steel company. Total revenues in 2007 were $105 billion. In October 2008, the market capitalisation of ArcelorMittal was over $30 billion.
