Overview
Mittal Steel Company N.V. was a multinational steel producer incorporated in the Netherlands and headquartered in the United Kingdom. It was the principal corporate vehicle through which Lakshmi Mittal and his family built a global steel business by acquiring, restructuring, and combining steel producers in emerging and developed markets. The company’s direct predecessor was Ispat International, while its broader business lineage traces to a steel operation founded by Lakshmi Mittal in 1989. The company began its international expansion by leasing the Iron & Steel Company of Trinidad & Tobago from the Trinidad and Tobago government in 1989. It subsequently acquired or took control of steel assets in Mexico, Canada, Europe, Kazakhstan, Ireland, the United States, Romania, Algeria, South Africa, Poland, Bosnia and Herzegovina, Macedonia, and Ukraine. This acquisition-led model allowed Mittal Steel to assemble a geographically diversified production network from facilities that were often state-owned, underperforming, or undergoing privatization. The company’s strategy emphasized operational improvement, international scale, and the integration of steelmaking, finishing, distribution, and related logistics. Important transactions included the acquisitions of Sibalsa in Mexico in 1992, Sidbec-Dosco in Canada in 1994, Hamburger Stahlwerke and Karmet Steel in 1995, Inland Steel Company in 1998, Unimétal in 1999, ALFASID and Sidex in 2001, and Iscor in South Africa in 2004. In the same year, the company acquired Polskie Huty Stali, BH Steel, and certain Macedonian facilities. Ispat International also merged with LNM Holdings in 2004 and adopted the Mittal Steel name, creating a larger consolidated platform for the family’s steel interests. Mittal Steel continued its expansion in 2005 by acquiring Tadeusz Sendzimir Steelworks, International Steel Group, and Kryvorizhstal in Ukraine. The Kryvorizhstal purchase followed the cancellation of an earlier privatization transaction that had been criticized as improperly priced and politically connected. Mittal Steel also announced major greenfield investment plans in India, including a proposed $9 billion project in Jharkhand and a planned 12-million-tonne-per-year plant in Odisha. The defining event in the company’s history was its acquisition of Arcelor. After a contested bid process, Mittal Steel raised its offer and reached an agreement in 2006. The transaction, valued at approximately $33 billion according to the cited reference material, was completed in August 2006 and created ArcelorMittal. As a condition associated with the combination, the Mittal family agreed to relinquish its controlling stake and accepted a standstill arrangement restricting further efforts to acquire control without approval from independent directors. Before the merger, Mittal Steel reported 110.5 million tonnes of steel production in 2006 and annual production capacity of 138 million tonnes. The combination with Arcelor made the resulting group one of the world’s largest steel producers. Mittal Steel therefore ceased to exist as an independent corporate brand after the 2006 transaction, although its assets, management heritage, and operating strategy became part of ArcelorMittal.
History
Mittal Steel Company was the product of a long acquisition program associated with Lakshmi Mittal. Its business lineage began in 1989, when the company leased the Iron & Steel Company of Trinidad & Tobago from the government. This initial transaction established the pattern that defined the group: entering steel markets through acquisitions, taking over facilities that were often state-owned or financially troubled, and managing them as part of an increasingly international network. The company expanded into Mexico in 1992 through the acquisition of Sibalsa and into Canada in 1994 through the purchase of Sidbec-Dosco. In 1995 it acquired Hamburger Stahlwerke, which contributed to the formation of Ispat International Ltd. and Ispat Shipping, and also acquired Karmet Steel in Temirtau, Kazakhstan. Irish Steel, Walzdraht Hochfeld, and Stahlwerk Ruhrort followed in 1996. The business became publicly traded through an initial public offering in 1997. Expansion continued in the United States with the acquisition of Inland Steel Company in 1998, followed by the acquisition of Unimétal in 1999. In 2001 the company acquired ALFASID and Sidex, extending its reach into North Africa and Eastern Europe. In 2004 it acquired a majority stake in Iscor, the South African steel producer that was renamed Mittal Steel South Africa. That year also brought the acquisition of Polskie Huty Stali, BH Steel, and selected Macedonian facilities from Balkan Steel. A major corporate reorganization took place in 2004, when Ispat International merged with LNM Holdings and was renamed Mittal Steel. The transaction unified previously separate parts of the Mittal family’s international steel interests. In January 2005, the company acquired Tadeusz Sendzimir Steelworks, and later that year it acquired International Steel Group, strengthening its North American position. Mittal Steel’s acquisition of Kryvorizhstal in Ukraine in October 2005 was particularly prominent. An earlier sale of the facility to a consortium connected to the family of former Ukrainian president Leonid Kuchma had been criticised as undervalued and politically influenced. After Viktor Yushchenko’s government cancelled that transaction, Mittal Steel won a new auction with a bid reported at $4.8 billion. The episode illustrated both the opportunities and political sensitivities associated with the company’s participation in post-socialist privatizations. The company also pursued greenfield development. In 2005 it announced a proposed $9 billion investment in Jharkhand, India, and in July 2006 announced plans for a steel plant in Odisha with proposed capacity of 12 million tonnes per year. These projects reflected an ambition to combine acquired production assets with new facilities in growing markets. Mittal Steel’s final and most consequential transaction was the acquisition of Arcelor. The bid was contested, and Mittal Steel increased its offer before reaching an agreement. The merger was completed in August 2006. To facilitate the combination, the Mittal family agreed to give up its controlling stake and entered into a standstill agreement limiting attempts to acquire control without the approval of independent directors. The resulting company, ArcelorMittal, brought together the two steel groups and became one of the world’s largest steel producers. Mittal Steel consequently became a historical predecessor rather than an operating company in its own right.
