Expansion of Seamless Tubular Products Business in the U.S.

Sumitomo Corporation (Chuo-ku, Tokyo; President and CEO: Susumu Kato; hereinafter "Sumitomo") hereby announces that it has acquired a 19.47% interest in V&M TWO LLC (President: Pascal Braquehais; hereinafter "V&M2"), a manufacturer of small-diameter seamless steel pipe based in the U.S. state of Ohio, from Vallourec S.A. (Paris, France; Chairman: Philippe Crouzet; hereinafter "Vallourec").

[V&M2 Project]
Development of unconventional energy resource has recently been growing in the United States, including oil and gas shale plays, for which production is expected to expand over the medium- to long-term. Concurrently, demand for the small-diameter seamless OCTG used in these shale plays is increasing. At a production facility it is being constructed nearby, V&M2 will manufacture these pipes and efficiently supply them to the major shale plays such as Marcellus Shale in Pennsylvania, one of the biggest OCTG consuming areas in the U.S..

[Overview of V&M2's steel pipe mill]
V&M2 has commenced construction of a production facility to manufacture small-diameter seamless steel pipes on a property adjacent to the premises of V&M STAR LP (President:Joel Mastervich; hereinafter "VMS"), another Ohio-based seamless steel pipe manufacturer, in which Sumitomo owns a 19.47% interest. The initial investment amount of the new steel pipe mill is approximately US$650 million, and scheduled to be completed for operational launch by mid-2012 and planned to go into full commercial operation by the end of that year with an annual output capacity of 350,000 tons.

[Sumitomo's strategy]
By taking a stake in V&M2, Sumitomo aims to enhance its seamless tubular products business in the Unites States and strengthen its long-term alliance with Vallourec. In relation to this, V&M2 is planning to integrate its business with that of VMS in the future. Sumitomo intends to leverage this integration to expand its business in the U.S. market.
