Regulatory News:

ArcelorMittal, the world's number one steel company, has announced its intention to acquire a 70% stake in Carminati Distribuzione S.r.l., one of the leading steel distributors in Northern Italy. The transaction has been approved by the competition authorities.

Italy is the 2nd largest European market in terms of both steel consumption and distribution. Conversely, the country has the most fragmented distribution sector in Europe.

ArcelorMittal already operates in Italy with two distribution companies, in Udine and Bologna. With this strategic position in Northern Italy, ArcelorMittal is demonstrating its determination to play a leading role in steel distribution in this country.

Carminati Distribuzione S.r.l. (ex Carminati Siderurgica S.p.A.), founded in 1960 and until now entirely owned by the Carminati family, employs 88 people in three sites (Brescia, Bergamo and Verona). It sold over 75,000 tonnes in 2006 with a turnover of 50 million euros. It specialises in finished long products with cutting, drilling and flame-cutting activities, for beams and angles. Its sales of sheets and plates, as well as of hot rolled bars and tubes, create a highly complementary product mix and activity which is aligned with ArcelorMittal Distribuzione Italia's strategy.

This newcomer in the distribution network will benefit from synergies with ArcelorMittal's European flat and long production plants, as well as support from the group's existing organisations.

Highly oriented towards its end users, Carminati is an efficient company with strongly motivated personnel which integrates perfectly within ArcelorMittal's growth plan.
