(the "Company" or "Tenaris"), a Luxembourg corporation (societe anonyme holding), was incorporated on December 17, 2001 as a holding company for investments in steel pipe manufacturing and distribution companies. The Company consolidates its subsidiary companies, as detailed in Note 32 to the audited Consolidated Financial Statements for the year ended December 31, 2006. These consolidated condensed interim financial statements have been prepared in accordance with IAS 34, "Interim Financial Reporting". The accounting policies used in the preparation of these consolidated condensed interim financial statements are consistent with those used in the audited consolidated financial statements for the year ended December 31, 2006. These consolidated condensed interim financial statements should be read in conjunction with the audited Consolidated Financial Statements for the year ended December 31, 2006, which have been prepared in accordance with International Financial Reporting Standards ("IFRS"). Certain comparative amounts have been reclassified to conform to changes in presentation in the current year. The preparation of consolidated condensed interim financial statements in conformity with IFRS requires management to make certain accounting estimates and assumptions that might affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities as of the balance sheet dates, and also the reported amounts of revenues and expenses for the reported periods. Actual results may differ from these estimates. Material intercompany transactions and balances between Tenaris subsidiaries have been eliminated in consolidation. However, some financial gains and losses do arise from intercompany transactions because certain subsidiaries use their respective local currencies as their functional currency for accounting purposes. Such gains and losses are included in the consolidated income statement under Other financial results. The Company applies hedge accounting treatment for certain qualifying financial instruments. These transactions are classified as cash flow hedges (mainly currency forward contracts on highly probable forecast transactions and interest rate swaps). The effective portion of the fair value of derivatives that are designated and qualify as cash flow hedges is recognized in equity. Amounts accumulated in equity are charged in the income statement in the periods when the hedged item affects profit or loss. The gain or loss relating to the ineffective portion is recognized in the income statement. The fair value of the Company's derivative financial instruments (asset or liability) is reflected on the Balance Sheet. For transactions designated and qualifying for hedge accounting, the Company documents at the time of designation of the transaction the relationship between hedging instruments and hedged items, as well as its risk management objectives. The Company also documents its assessment at hedge designation and at each period end of whether the derivatives that are used in hedging transactions are expected to be effective in offsetting changes in cash flows of hedged items. At March 31, 2007, the effective portion of designated cash flow hedges amounts to $1.5 million and is included in Other reserves in equity. These consolidated condensed interim financial statements were approved for issue by the Tenaris Board of Directors on May 4, 2007. 2 Segment information Reportable operating segments --------------------------------------------------------------------------- (all amounts in thousands of U.S. dollars) Total Continuing Total Discontinued Tubes Projects Other operations operations (*) --------------------------------------------------------------------------- Three-month period ended March 31, 2007 (Unaudited) Net sales 2,144,728 124,410 156,161 2,425,299 - Cost of sales (1,081,759) (82,216) (127,523) (1,291,498) - --------------------------------------------------------------------------- Gross profit 1,062,969 42,194 28,638 1,133,801 - Selling, general and administrative expenses (337,215) (17,642) (19,410) (374,267) - Other operating income (expenses), net (3,726) 1,758 31 (1,937) - --------------------------------------------------------------------------- Operating income 722,028 26,310 9,259 757,597 - Depreciation and amortization 89,720 4,425 6,342 100,487 - Three-month period ended March 31, 2006 Net sales 1,448,044 96,225 77,622 1,621,891 161,261 Cost of sales (693,903) (63,025) (59,399) (816,327) (156,165) --------------------------------------------------------------------------- Gross profit 754,141 33,200 18,223 805,564 5,096 Selling, general and administrative expenses (190,211) (17,206) (9,223) (216,640) (1,244) Other operating income (expenses), net 8,302 316 (433) 8,185 (55) --------------------------------------------------------------------------- Operating income 572,232 16,310 8,567 597,109 3,797 Depreciation and amortization 46,710 4,865 2,667 54,242 433 Geographical information (all amounts in thousands of U.S. dollars) Middle Total Total North South East & Far East & Continuing Discontinued America America Europe Africa Oceania operations operations (*) -------------------------------------------------------------------------- Three-month period ended March 31, 2007 (Unaudited) Net sales 802,140 428,775 426,615 601,250 166,519 2,425,299 - Depreciation and amortization 59,319 24,439 14,848 197 1,684 100,487 - Three-month period ended March 31, 2006 Net sales 467,599 343,374 306,552 331,070 173,296 1,621,891 161,261 Depreciation and amortization 15,422 22,510 14,616 209 1,485 54,242 433 Allocation of net sales to geographical segments is based on customer location.

Significant changes or events since the date of such financial statements are the following: Asbestos-related Litigation In addition to the previously known 13 civil proceedings for work-related injuries arising from the use of asbestos in its manufacturing processes during the period from 1960 to 1980, 18 asbestos-related out-of-court claims and 1 civil party claim, 21 new asbestos-related out-of-court claims and 1 asbestos civil proceedings have been notified to Dalmine during 2007; no claims were dismissed or settled. Accordingly, as of March 31, 2007, the total asbestos-related claims pending against Dalmine are 54 (of which, 3 are covered by insurance). Aggregate settlement costs to date are Euro 3.8 million. Dalmine estimates that its potential liability in connection with the claims above that are not yet settled is approximately Euro 20.4 million ($ 27.2 million) of which Euro 7.8 million ($10.4 million) relate to the claims and proceedings notified to Dalmine during 2007. 7 Contingencies, commitments and restrictions to the distribution of profits (Cont'd) Asbestos-related Litigation (Cont'd) Accruals for Dalmine's potential liability are based on the average of the amounts paid by Dalmine for asbestos-related claims plus an additional amount related to some reimbursements requested by the social security authority. The maximum potential liability is not determinable as in some cases the requests for damages do not specify amounts, and instead is to be determined by the court. The timing of payment of the amounts claimed is not presently determinable. Maverick litigation On December 11, 2006, The Bank of New York ("BNY"), as trustee for the holders of Maverick 2004 4% Convertible Senior Subordinated Notes due 2033 issued pursuant to an Indenture between Maverick and BNY ("Noteholders"), filed a complaint against Maverick and Tenaris in the United States District Court for the Southern District of New York. The complaint alleges that Tenaris's acquisition of Maverick triggered the "Public Acquirer Change of Control" provision of Indenture, asserting breach of contract claim against Maverick for refusing to deliver the consideration specified in the Public Acquirer Change of Control provision of the Indenture to Noteholders who entered their notes for such consideration. This complaint seeks a declaratory judgement that Tenaris's acquisition of Maverick was a Public Acquirer Change of Control under the Indenture, and asserts claims for tortuous interference with contract and unjust enrichment against Tenaris. Defendants filed a motion to dismiss the complaint, or in the alternative, for summary judgment on March 13, 2007. Plaintiff filed a motion for partial summary judgment on the same date. Opposition papers to the motions were filed due April 20, 2007, and reply papers are due May 15, 2007. Tenaris believes that these claims are without merit. Accordingly, no provision was recorded in these financial statements. Were plaintiff to prevail, Tenaris estimates that the recovery would be approximately $50 million. European Commission Fine On January 25, 2007, the Court of Justice of the European Commission confirmed the December 8, 1998 decision by the European Commission to fine eight international steel pipe manufacturers, including Dalmine, for violation of European competition laws. Pursuant to the Court's decision, Dalmine is required to pay a fine of Euro 10.1 million ($13.3 million). Since the infringements for which the fine was imposed took place prior to the acquisition of Dalmine by Tenaris in 1996, Dalmine's former owner, who had instructed Dalmine to appeal, is required and has acknowledged its responsibility to pay 84.1% of the fine. The remaining 15.9% of the fine has been paid out in 2007 of the provision that Dalmine established in 1999 for such proceeding. Employee retention and incentive program Tenaris has adopted an employee retention and long term incentive program effective from January 1, 2007. Pursuant to this program, certain senior executives will be granted a number of units equivalent in value to the equity book value per share (excluding minority interest). The units will be vested over a period of four years and the Company will redeem vested units following a period of ten years from the grant date, or when the employee leaves the Company, at the equity book value per share at the time of payment. Beneficiaries will also receive a cash amount per unit equivalent to the dividend paid per share whenever the Company pays a dividend to its shareholders. Compensation under this program is not expected to exceed 35% in average of the total annual compensation of the beneficiaries. The total value of the units granted to date under the program, considering the number of units and the book value per share as of March 31, 2007, is $4.7 million.
