Tenaris to Complete Acquisition of Maverick Tube Corporation on October 5, 2006 LUXEMBOURG--(BUSINESS WIRE)--Oct. 2, 2006--Tenaris S.A. (NYSE:TS) (BCBA:TS) (BMV:TS) (BI:TEN) announced that, following the vote today by a majority of Maverick Tube Corporation's stockholders in favor of the proposed acquisition by Tenaris, the acquisition should be completed on October 5, 2006. On that date, Tenaris will transfer to the paying agent for the transaction US$65 per share in cash for each issued and outstanding share of Maverick's common stock and a subsidiary of Tenaris will merge with and into Maverick. To finance the acquisition and the payment of related obligations (including outstanding indebtedness of Maverick), Tenaris and some of its subsidiaries have entered into syndicated term loan facilities in an aggregate of up to US$2.7 billion; the balance will be met from cash on hand. Citibank and BNP Paribas have acted as global coordinators, lead arrangers and bookrunners for the syndicated loan facilities. Tenaris will consolidate Maverick's balance sheet and results of operations in its consolidated financial statements beginning in the fourth quarter of 2006. German Cura, who has been appointed as Area Manager of Tenaris's operations in North America (USA and Canada), will lead the integration of Maverick's operations into those of Tenaris. Tenaris will move promptly to integrate Maverick into its global industrial and commercial system and to market Maverick's products and services under the Tenaris brand. Tenaris's operations in the United States and Canada have grown rapidly since it began operating the AlgomaTubes seamless pipe mill in 2000; with Maverick, Tenaris will be a leading supplier of OCTG products and services in North America able to support its customers with the full range of applications from onshore shallow wells to extremely demanding deepwater wells in the Gulf of Mexico.
