On the 10th June 2008, the European Commission released notification of non-opposition to a concentration between ArcelorMittal and Borusan. Dating back to the 3rd June 2008 when the Commission decided not to oppose the above notified concentration and to declare it compatible with the common market.

The business activities concerned are:

ArcelorMittal is the world's number one steel company, with 310,000 employees in more than 60 countries. It has led the consolidation of the world steel industry and today ranks as the only truly global steelmaker. ArcelorMittal is the leader in all major global markets, including automotive, construction, household appliances and packaging. The Group leads in R&D and technology, holds sizeable captive supplies of raw materials and operates extensive distribution networks.

Borusan Holding is a steel pipe company Borusan and Borusan Mannesman were merged in 2004 under the name Borusan Mannesman Boru. Borçelik, the first privately owned flat steel company in the country and Borusan Mannesman Boru, currently one of Europe’s five leading pipe producers, are among the leading companies in Turkey. Borusan Mannesman Boru became a “European producer” when it bought Structo Vobarno plant in Italy in 2001. During the same year, Borçelik and Arcelor, the largest steel producers in the world, started a gargantuan joint investment of US$ 140 million. Increasing its yearly production capacity to 1 million tons upon the conclusion of the investment in 2004, Borçelik started manufacturing in EU standards. The purchase of 35% shares of Bamesa Aceros in Spain in 2002 constituted a new step towards the European market.
