Following the agreement to sell the Hydril pressure control business to GE, the pressure control segment was reclassified in our financial statements as a discontinued operation.

Our fourth quarter results show a partial recovery at the operating level compared to the third quarter, with operating income returning to the levels recorded in the first two quarters of the year but remaining below the strong level recorded in the fourth quarter of 2006. Our net income for the quarter further benefitted from a reduced income tax charge and a gain recorded on the sale of our remaining 25% interest in Dalmine Energie. Free cash flow (net cash provided by operations less capital expenditures) totaled US$118.1 million, and net debt at December 31, 2007 was US$2,970.2 million following the payment of an interim dividend.

Summary of 2007 Annual Results

                                                                 Increase/

Following several years of strong growth, earnings per share declined marginally in 2007 compared to 2006. Net sales, EBITDA and operating income, on the other hand continued to grow, up 30%, 13% and 6% respectively. These stable results reflect steady overall demand for our products and services from the global oil and gas industry. They were achieved in a context of rising costs and a severe decline in Canadian gas drilling activity.

We expect our sales to increase in 2008, led by higher sales of specialized, high-end OCTG products, and that the increase in sales should result in higher operating and net income. However, increased volatility in economic conditions and raw material and commodity prices could affect market conditions for our products and services and, consequently, our results for the second half of the year.

Annual Dividend Proposal

The board of directors proposes, for the approval of the annual general shareholders' meeting to be held on June 4, 2008, the payment of an annual dividend of US$0.38 per share (US$0.76 per ADS), or approximately US$450 million, which includes the interim dividend of US$0.13 per share (US$0.26 per ADS) paid on November 22, 2007. This would represent an increase of 27% over the annual dividend paid for the 2006 fiscal year. If the annual dividend is approved by the shareholders, a dividend of US$0.25 per share (US$0.50 per ADS), or approximately US$295 million will be paid on June 26, 2008 with a record date of June 25, 2008 and an ex-dividend date of June 23, 2008.

Market Background and Outlook

In 2007, global demand for oil and gas continued to rise reflecting economic growth and the importance of oil and gas in the energy matrix. Encouraged by continuing high levels of oil prices, oil and gas companies in most regions of the world continued to increase their level of spending and drilling activity to offset declining rates of production from mature fields and to explore and develop new reserves. In Canada, however, subdued North American gas prices affected gas drilling activity.

The international count of active drilling rigs, as published by Baker Hughes, after rising steadily in the first three quarters of the year dipped marginally in the fourth quarter to average 1017, an increase of 7% compared to the same quarter of the previous year. The average increase for the full year, compared to 2006, was 9%.

The corresponding rig count in the USA, which is more sensitive to North American gas prices, also showed a positive, though decelerating, trend during the year. It showed an average annual increase of 7% in 2007 compared to 2006 and in the fourth quarter of 2007 was up 4% compared to the fourth quarter of 2006. The corresponding rig count in Canada, however, which began to decline in the second half of 2006, showed an average annual decline of 27% compared to 2006 and a decline of 19% in the fourth quarter compared to the same period of 2006.

We estimate that global apparent demand for OCTG in 2007 remained similar to that in 2006, following strong growth in the previous three years, as an increase in operative consumption was offset by inventory adjustments. We expect growth in apparent demand to resume in 2008 based on continued growth in oil and gas drilling activity outside North America and the maintenance of current levels of drilling activity in North America. However, the annual growth rate is expected to be lower than in the period 2004-2006 and may be affected by market volatility and inventory adjustments in some markets.

Demand for our large diameter pipes for pipeline projects in South America was strong in 2007 as major gas pipeline infrastructure projects in Brazil and Argentina, which had previously been delayed, went forward. Orders for new projects in Brazil and Colombia have been received and we expect to maintain a strong level of sales in this segment in 2008.

Steelmaking raw material costs rose in 2007 and are expected to rise more steeply in 2008. Energy and labor costs also rose during 2007, and may rise further in 2008, with labor costs being affected primarily by currency-related factors. Steel costs for our welded pipe products also rose and are expected to increase further in 2008.

Net sales of tubular products and services rose 1% to US$2,153.0 million in the fourth quarter of 2007, compared to US$2,132.5 million in the fourth quarter of 2006, as an increase in our average selling price for tubular products and services offset a 2% decline in sales volume. Sales rose strongly in South America, led by increased sales of OCTG products in Venezuela, and in Europe, where average selling prices increased due to a stronger product mix and the appreciation of the euro against the U.S. dollar. Sales declined in Middle East and Africa compared to the strong level of sales recorded in the fourth quarter of 2006 due primarily to lower sales in Saudi Arabia. In North America, an increase in sales in USA was offset by a decline in sales in Canada, where gas drilling activity continues to decline year on year, and in Mexico, where weather conditions affected drilling activity.

Net sales of pipes for pipeline projects rose 83% to US$315.4 million in the fourth quarter of 2007, compared to US$172.4 million in the fourth quarter of 2006, reflecting a high level of deliveries to gas pipeline projects in Brazil and the partial resumption of deliveries to the loops expansion project in Argentina. Operating income in this segment in the fourth quarter of 2007 included other operating income of US$16.4 million in respect of the sale of surplus office space.

Net sales of other products and services rose 2% to US$159.6 million in the fourth quarter of 2007, compared to US$156.3 million in the fourth quarter of 2006, as higher sales of metallic equipment offset lower sales of hot briquetted iron from our plant in Venezuela.

Selling, general and administrative expenses, or SG&A, increased as a percentage of net sales to 15.7% in the quarter ended December 31, 2007 compared to 14.1% in the corresponding quarter of 2006 due primarily to an increase in amortization expenses following the incorporation of Hydril. Amortization of customer relationships and other intangibles acquired with Hydril amounted to US$19.8 million in the quarter, or 0.8% of net sales.

Other operating income included a gain of US$16.4 million in relation to the sale of surplus office space in Brazil (as mentioned above).

Net interest expense rose to US$41.8 million in the fourth quarter of 2007 compared to a net interest expense of US$33.5 million in the same period of 2006 reflecting an increased net debt position following the Hydril acquisition.

Other financial results contributed a loss of US$12.0 million during the fourth quarter of 2007, compared to a gain of US$18.2 million during the fourth quarter of 2006.

Equity in earnings of associated companies generated a gain of US$39.7 million in the fourth quarter of 2007, compared to a gain of US$17.9 million in the fourth quarter of 2006. The result in the fourth quarter of 2007 included a gain of US$18.4 million recorded on the sale of our remaining 25% participation in Dalmine Energie and the balance was derived mainly from our equity investment in Ternium.

Income tax charges totalled US$159.2 million in the fourth quarter of 2007. This result included reductions in deferred tax liabilities due to tax rate changes in Canada, Italy and Colombia and net non-recurring tax losses of US$47.3 million.

Income from discontinued operations amounted to US$12.4 million in the fourth quarter of 2007. This income corresponds to the Hydril pressure control business, which was classified as a discontinued operation following the conclusion of an agreement to sell this business on January 28, 2008.

Income attributable to minority interest rose to US$49.3 million in the fourth quarter of 2007, compared to US$37.2 million in the corresponding quarter of 2006 reflecting higher operating and financial results at our Confab subsidiary.

Cash Flow and Liquidity

Net cash provided by operations during the fourth quarter of 2007 was US$231.5 million (US$2,020.6 million for the year), compared to US$499.0 million in the fourth quarter of 2006 (US$1,810.9 million during the year). Working capital increased by US$205.1 million during the fourth quarter with the value of inventories rising by US$114.8 million and advance payables, mainly associated with our Project segment, declining by US$36.5 million.

Capital expenditures amounted to US$113.3 million for the fourth quarter of 2007 and US$447.9 million for the year, compared to US$139.4 million in the fourth quarter of 2006 and US$441.5 million for the year. During 2007 we completed a two-year investment program to increase capacity for specialized products and commissioned, among other facilities, new heat treatment facilities in Mexico and Argentina, a new premium threading facility in China, a new power generation plant in Italy and a new components center in Romania.

During 2007, total financial debt increased by US$369.0 million to US$4,020.2 million at December 31, 2007 from US$3,651.2 million at December 31, 2006, as additional debt was used to finance the acquisition of Hydril and liquidity (cash and cash equivalents and other current investments) was reduced. Net financial debt during 2007 increased by US$874.9 million to US$2,970.2 million at December 31, 2007.

Net sales of tubular products and services rose 25% to US$8,552.6 million in 2007, compared to US$6,826.9 million in 2006, due to a higher volume of welded pipe sales, resulting from the incorporation of the former Maverick operations acquired in October 2006, and a higher average selling price for our seamless pipes reflecting an enhanced product mix and increased demand for our specialized, high-end seamless pipe products used in the world's more complex drilling operations and other demanding applications. In North America, sales increased principally due to the incorporation of sales from the former Maverick and Hydril premium connection operations but, excluding such effects, there was a substantial decline in sales in Canada reflecting the decline in drilling activity and consequent inventory adjustments. In South America, sales increased due primarily to higher sales of OCTG products in Venezuela as PDVSA began to replenish inventories and increased sales in Colombia. In Europe, sales increased, with higher average selling prices and volumes, reflecting higher sales to European-based process and power plant contractors, a more specialized mix of products sold to industrial and automotive customers, increased sales of OCTG products in continental Europe and the appreciation of the Euro with respect to the U.S. dollar. In the Middle East and Africa, higher average selling prices more than offset lower volumes which were affected by lower sales of API OCTG products and inventory adjustments. In the Far East and Oceania, sales remained stable with higher sales in South-East Asia and South Korea offsetting lower sales in China.

Operating income from tubular products and services rose 2% to US$2,713.9 million in 2007, from US$2,670.5 million in 2006, as the increase in sales was substantially offset by a reduction in the gross margin and higher expenses for the amortization of intangible assets.

Net sales of pipes for pipeline projects rose 93% to US$876.3 million in 2007, compared to US$453.5 million in 2006, due to higher shipments and average selling prices. Regional demand for pipes for pipeline projects in South America improved substantially in 2007 as large gas pipeline projects in Brazil and Argentina that had been delayed in 2006 went ahead and orders were received for mineral slurry and additional gas pipeline projects in Brazil.

Operating income from pipes for pipeline projects rose 228% to US$184.8 million in 2007, from US$56.3 million in 2006, due to the increase in net sales and an increase in the operating margin reflecting a higher proportion of sales in Brazil where sales from our Brazilian mill have low logistics costs. Operating income in this segment in 2007 included other operating income of US$16.4 million in respect of the sale of surplus office space.

Net sales of other products and services rose 37% to US$613.1 million in 2007, compared to US$447.3 million in 2006, as sales from electric conduit pipe operations acquired in October 2006 were included for a full year. Sales of metallic structures also increased but sales of excess raw materials and sucker rods declined.

Selling, general and administrative expenses, or SG&A, increased as a percentage of net sales to 15.7% in 2007 compared to 13.6% in 2006 due mainly to increased charges for amortization of intangible assets relating principally to assets acquired in the Maverick and Hydril acquisitions. These amortization charges amounted to US$236.0 million in 2007, or 2.4% of net sales, compared to US$54.8 million, or 0.7% of net sales, in 2006.

Other operating income and expenses resulted in net income of US$4.9 million in 2007, compared to net income of US$3.8 million in 2006. The 2007 result included income of US$16.4 million in relation to the sale of surplus office space in Brazil and an expense of US$10.3 million relating to the settlement of redemptions on Maverick's 2005 Notes.

Net interest expenses totalled US$182.3 million in 2007, compared to net interest expenses of US$31.8 million in 2006. The increase in net interest expenses reflects the increase in the average net debt position during 2007 compared to 2006, relating to debt contracted for the Maverick and Hydril acquisitions.

Other financial results contributed a loss of US$22.8 million in 2007, compared to a gain of US$26.8 million during 2006. These results largely reflect gains and losses on net foreign exchange transactions and the fair value of derivative instruments and are to a large extent offset by changes to our net equity position. They arise due to the fact that most of our subsidiaries prepare their financial statements in currencies other than the US dollar in accordance with IFRS.

Equity in earnings of associated companies generated a gain of US$113.3 million in 2007, compared to a gain of US$94.7 million in 2006. These gains were derived mainly from our equity investment in Ternium but, in 2007, also included a gain of US$18.4 million recorded on the sale of our remaining 25% participation in Dalmine Energie.

Income tax charges of US$823.9 million were recorded during 2007, equivalent to 30% of income before equity in earnings of associated companies and income tax, compared to income tax charges of US$870.0 million, equivalent to 31% of income before equity in earnings of associated companies and income tax, during 2006. The result in 2007 included net non-recurring tax losses of US$47.3 million.

Income from discontinued operations amounted to US$34.5 million, compared to US$47.2 million in 2006. The 2007 income corresponds to the Hydril pressure control business, which was classified as a discontinued operation following the conclusion of an agreement to sell this business on January 28, 2008. The 2006 income corresponds to our former Dalmine Energie energy supply subsidiary, in which we sold a majority participation in December 2006.

Net income rose marginally to US$2,076.1 million in 2007, compared to US$2,059.4 million in 2006, as an increase in operating income was largely offset by an increase in net interest expenses.

Income attributable to equity holders was US$1,923.7 million, or US$1.63 per share (US$3.26 per ADS), in 2007, compared to US$1,945.3 million, or US$1.65 per share (US$3.30 per ADS) in 2006.

Income attributable to minority interest was US$152.3 million in 2007, compared to US$114.1 million in 2006. The increase was due primarily to higher income attributable to minority interest at our Confab subsidiary.
