(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 31 to the audited Consolidated Financial Statements for the year ended December 31, 2005, and modified as discussed in Note 9 to these consolidated condensed interim financial statements. 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, 2005. These consolidated condensed interim financial statements should be read in conjunction with the audited Consolidated Financial Statements for the year ended December 31, 2005, which have been prepared in accordance with International Financial Reporting Standards ("IFRS"). 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 Financial income (expenses), net. 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 September 30, 2006, the effective portion of designated cash flow hedges amounts to $1.2 million and is included in Other reserves in equity. Upon the adoption of IFRS 3, which was adopted together with the revised IAS 38, "Intangible Assets", and IAS 36, "Impairment of Assets", previously accumulated negative goodwill is required to be derecognized through an adjustment to retained earnings. The derecognition of negative goodwill in this manner resulted in an increase of $110.8 million in the beginning balance of the Company's equity at January 1, 2005. These consolidated condensed interim financial statements were approved for issue by the Tenaris Board of Directors on November 8, 2006. 3 2 Segment information Primary reporting format: business segments ------------------------------------------------------------------------- (all amounts in thousands of U.S. dollars) Welded & Other Seamless Metallic Products Energy Other Total ------------------------------------------------------------------------- Nine-month period ended September 30, 2006 (Unaudited) Net sales 4,657,469 362,519 403,722 244,198 5,667,908 Cost of sales (2,151,812) (262,752) (390,534) (168,917) (2,974,015) ------------------------------------------------------------------------- Gross profit 2,505,657 99,767 13,188 75,281 2,693,893 Depreciation and amortization 140,241 15,879 1,503 8,385 166,008 Nine-month period ended September 30, 2005 Net sales 3,667,049 636,849 362,593 171,132 4,837,623 Cost of sales (1,987,376) (425,808) (354,959) (103,688) (2,871,831) ------------------------------------------------------------------------- Gross profit 1,679,673 211,041 7,634 67,444 1,965,792 Depreciation and amortization 133,040 11,185 1,973 10,456 156,654 Secondary reporting format: geographical segments ------------------------------------------------------------------------- (all amounts in thousands of U.S. dollars) Middle South North East & Far East & America Europe America Africa Oceania Total ------------------------------------------------------------------------- Nine-month period ended September 30, 2006 (Unaudited) Net sales 1,091,230 1,394,850 1,321,558 1,335,281 524,989 5,667,908 Depreciation and amortization 69,723 46,306 44,940 583 4,456 166,008 Nine-month period ended September 30, 2005 Net sales 1,353,356 1,114,478 1,281,329 636,435 452,025 4,837,623 Depreciation and amortization 62,151 53,755 35,925 50 4,773 156,654 Allocation of net sales to geographical segments is based on customer location.

This amount included the interim dividend paid in November, 2005, in the amount of $0.127 per share or approximately $149.9 million. Tenaris paid the balance of the annual dividend amounting to approximately $204.2 million corresponding to $0.173 per share during 2006. During 2005 Tenaris paid $199.5 million corresponding to $0.169 per share. 8 Contingencies, commitments and restrictions to the distribution of profits This note should be read in conjunction with Note 26 to the Company's audited Consolidated Financial Statements for the year ended December 31, 2005. Significant changes or events since the date of such financial statements are the following: (i) Commitments (a) In August 2001, Dalmine Energie S.p.A. ("Dalmine Energie") entered into a ten-year contract ending October 1, 2011 with Eni S.p.A. Gas & Power Division ("Eni") for the purchase of natural gas with certain take-or-pay conditions. The outstanding value of these commitments at September 30, 2006 amounts to approximately EUR701.9 million ($888.6 million). (b) Under the Gas Release Program enacted by Eni, in August 2004, Dalmine Energie increased its supply of natural gas for the period from October 1, 2004 to September 30, 2008. The gas purchase and sale agreements entered into with Eni contain customary take-or-pay conditions. The additional gas supply mentioned above is valued at approximately EUR205.2 million ($259.8 million), based on prices prevailing at September 2006. Dalmine Energie has also obtained the necessary capacity on the interconnection infrastructure at the Italian border to transport the natural gas to Italy for the supply period. (c) Dalmine Energie has entered into arrangements and expects to obtain additional gas transportation capacity on the Trans Austria Gasleitung GmbH ("TAG") pipeline, which is presently under construction. This capacity will allow Dalmine Energie to import an incremental 1,176.5 million cubic meters of natural gas per year. The additional transportation capacity, which is subject to "ship or pay" provisions, will be available on a firm basis on the TAG pipeline beginning October 2008 and through September 2028. The expected annual value of this "ship or pay" commitment is approximately EUR5.0 million per year. Tenaris provided bank guarantees in the amount of EUR15.1 million in support of Dalmine Energie. The value of the bank guarantees corresponds to the termination penalties that would be due to TAG in the event of termination due to shipper's default. 6 8 Contingencies, commitments and restrictions to the distribution of profits (Cont'd) (ii) Restrictions to the distribution of profits and payment of dividends As of September 30, 2006, shareholders' equity as defined under Luxembourg law and regulations consisted of the following: (all amounts in thousands of U.S. dollars) (unaudited) Share capital 1,180,537 Legal reserve 118,054 Share premium 609,733 Retained earnings including net income for the nine-month period ended September 30, 2006 1,392,057 ------------------- Total shareholders equity in accordance with Luxembourg law 3,300,381 ------------------- At least 5% of the net income per year as calculated in accordance with Luxembourg law and regulations must be allocated to the creation of a legal reserve equivalent to 10% of share capital. As of September 30, 2006, this reserve is fully allocated and additional allocations to the reserve are not required under Luxembourg law. Dividends may not be paid from this reserve. Tenaris may pay dividends to the extent, among other conditions, that it has distributable retained earnings calculated in accordance with Luxembourg law and regulations. At September 30, 2006, Tenaris's retained earnings under Luxembourg law totalled $1,392.1 million, as detailed below. (all amounts in thousands of U.S. dollars) (unaudited) Retained earnings at December 31, 2005 under Luxembourg law 1,171,738 Dividends received 416,831 Other income and expenses for the nine-month period ended September 30, 2006 7,721 Dividends paid (204,233) ------------------- Retained earnings at September 30, 2006 under Luxembourg law 1,392,057 ------------------- 9 Business acquisitions, incorporation of subsidiaries and other significant events (a) Acquisition of Maverick Tube Corporation ("Maverick") On October 5, 2006, Tenaris completed its acquisition of Maverick, pursuant to which, Maverick merged with and into a wholly owned subsidiary of Tenaris. On that date, Tenaris transferred to the paying agent for the transaction $65 per share in cash for each issued and outstanding share of Maverick's common stock. The transaction was valued at $3,185 million, including Maverick's net debt. To finance the acquisition and the payment of related obligations, Tenaris and some of its subsidiaries entered into syndicated five-year term loan facilities in an aggregate of up to $2.7 billion; the balance was met from cash on hand. Tenaris will consolidate Maverick's balance sheet and results of operations in its consolidated financial statements beginning in the fourth quarter of 2006. With operations in the United States, Canada and Colombia, Maverick is a producer of welded oil country tubular goods (OCTG), line pipe and coiled tubing for use in oil and natural gas wells, also producing welded pipes for electrical conduits. Maverick has a combined annual capacity of two million short tons of steel pipes with a size range from one-quarter inch to 16 inches, and approximately 4,650 employees. In 2005, Maverick reported net revenues of approximately $1.8 billion, of which 82% were from its energy products division. 7 9 Business acquisitions, incorporation of subsidiaries and other significant events (Cont'd) (b) Letter of intent relating to sale of 75% interest in Dalmine Energie On September 13, 2006, Tenaris signed a letter of intent with E.ON Sales and Trading GmbH, an indirect subsidiary of E.ON AG, for the sale to E.ON of a 75% interest in Dalmine Energie, Tenaris's Italian energy supply business, for a purchase price of approximately EUR39 million, subject to adjustments. The transaction, which is subject to negotiation and execution of definitive documentation, clearance by the applicable competition authorities and customary due diligence conditions, is expected to close before the end of 2006. The Company cannot give assurance that the transaction will be completed. Should it be completed, Tenaris will represent the results of Dalmine Energie as results of discontinued operations in accordance with the requirements of IFRS 5 "Non-current Assets Held for Sale and Disontinued Operations". (c) Investment in Ternium S.A. ("Ternium") On September 9, 2005, the Company exchanged its 21.2% equity interest in Consorcio Siderurgia Amazonia Ltd. ("Amazonia") and its 24.4% equity interest in Ylopa Servicos de Consultadoria Ltda. ("Ylopa"), for 209,460,856 shares in Ternium, the company into which San Faustin N.V. (a Netherlands Antilles corporation and the controlling shareholder of Tenaris) consolidated its Latin American holdings in flat and long steel producers Siderar S.A.I.C. ("Siderar"), Sidor C.A. ("Sidor") and Hylsamex, S.A de C.V. As a result of the exchange, which was carried out based on fair values as determined by an internationally recognized investment bank engaged for this purpose, Tenaris obtained an initial ownership interest of approximately 17.9% in Ternium. Subsequently, on October 27, 2005, Usinas Siderurgicas de Minas Gerais S.A. reached an agreement with Ternium to exchange its interests in Amazonia, Ylopa and Siderar, plus additional consideration of approximately $114.1 million provided as a convertible loan, for an equity stake in Ternium. As a consequence of the additional shares issued under this transaction, Tenaris' ownership stake was reduced to 15.0% of Ternium's outstanding common stock at December 31, 2005. The effect of this transaction resulted in an increase of the Company's proportional ownership in Ternium's equity of approximately $2.7 million, which Tenaris recognized in Other Reserves in equity. In addition, in August 2005 Tenaris extended to Ternium two subordinated convertible loans consisting of principal amount of $39.7 million. The principal amount of these loans at the date issued corresponded to the amount of certain distributions received from Amazonia during the second and third quarters of 2005 in connection with Ternium's participation in Amazonia's financial debt restructuring in 2003. At the date of Ternium's initial public offering ("IPO"), the loans totaled approximately $40.5 million, including accrued interest. On February 6, 2006, Ternium completed its IPO, issuing an additional 248,447,200 shares (equivalent to 24,844,720 ADS) at a price of $2.00 per share, or $20.00 per ADS. Tenaris received an additional 20,252,338 shares upon the mandatory conversion of its loans to Ternium. In addition to the shares issued to Tenaris, Ternium issued shares to other shareholders corresponding to their mandatory convertible loans. On February 23, 2006, the underwriters of Ternium's IPO exercised an overallotment option under which Ternium issued an additional 37,267,080 shares (equivalent to 3,726,708 ADS). As a result of the IPO and the conversion of loans, as of February 6, 2006, Tenaris' ownership stake in Ternium amounted to 11.46%. The effect of these transactions resulted in an additional increase of the Company's proportional ownership in Ternium's equity of approximately $27.7 million, which Tenaris recognized in Other Reserves in equity. At September 30, 2006, the closing price of Ternium shares as quoted on the New York Stock Exchange was $23.16 per ADS, giving Tenaris' ownership stake a market value of approximately $532 million. At September 30, 2006, the carrying value of Tenaris's ownership stake in Ternium was approximately $389 million. 8 9 Business acquisitions, incorporation of subsidiaries and other significant events (Cont'd) (d) Acquisition of Welded Pipe Business in Argentina On January 31, 2006, Siat S.A., a subsidiary of Tenaris, completed its acquisition of the welded pipe assets and facilities located in Villa Constitucion, province of Santa Fe, Argentina, belonging to Industria Argentina de Acero, S.A. ("Acindar") for $29.3 million.
