Tenaris Announces 2005 First Quarter Results LUXEMBOURG--(BUSINESS WIRE)--May 2, 2005--Tenaris S.A. (NYSE:TS) (BCBA:TS) (BMV:TS) (BI:TEN) -- The financial and operational information contained in this press release is based on unaudited consolidated condensed interim financial statements prepared in accordance with International Financial Reporting Standards (IFRS) and presented in U.S. dollars. Tenaris S.A. (NYSE:TS) (BCBA:TS) (BMV:TS) (BI:TEN) ("Tenaris") today announced its results for the quarter ended March 31, 2005 with comparison to its results for the quarter ended March 31, 2004. Summary of 2005 First Quarter Results Q1 2005 Q1 2004 Increase Net sales (US$ million) 1,452.9 859.3 69% Operating income (US$ million) 405.7 102.6 296% Net income (US$ million)(1) 280.0 47.6 488% Shareholders' net income (US$ million) 264.2 48.4 446% Net earnings per ADS (US$) 2.24 0.41 446% Net earnings per share (US$) 0.224 0.041 446% EBITDA(2) (US$ million) 457.7 156.4 193% EBITDA margin (% of net sales) 31% 18% (1) As required by IAS 1 (revised) as from January 1, 2005 net income for the period shown in the income statement does not show minority interest. Net earnings per share continue to be calculated on the net income attributable to the equity holders of Tenaris. (2) EBITDA equals operating income plus depreciation and amortization charges. These results build on the positive trend in our results, excluding non-recurring items, shown in all four quarters of 2004. As the leading suppliers of seamless pipe products to the global energy industry, we continue to benefit from increases in investment in oil and gas exploration and production. Net sales increased 14% sequentially, due to a 10% increase in average selling prices for our seamless pipes and much stronger demand for our welded pipes. Our consolidated EBITDA and operating margins rose significantly above the levels recorded in previous years as the sequential increase in seamless pipe selling prices was not accompanied by an equivalent increase in the average cost of goods sold. In addition, our welded pipe business had higher margins on increased demand from pipeline construction projects in the regional market of our two welded pipe mills. Free cash flow was also positive and net debt declined by US$179.4 million to US$648.7 million during the quarter. Market Background and Outlook Global demand for seamless pipes continues to increase led by higher drilling activity in the oil and gas industry. The international count of active drilling rigs, as published by Baker Hughes, averaged 876 during the first quarter of 2005, an increase of 10% compared to the same quarter of the previous year, with significant increases shown in the Middle East and Venezuela. As a result of strong market demand and limited capacity availability, particularly for the high-end pipes in which Tenaris increasingly specializes, our average selling price for seamless pipe products has been increasing and we expect that it will increase further during 2005 but at a slower rate than that shown in the previous two quarters. After the strong rise in most of our steelmaking raw material costs in the second half of 2003 and in 2004, international prices for scrap steel, DRI and pig iron have been mainly flat since the end of the year. On the other hand, the prices of some ferroalloys continued to increase in the first quarter of 2005 and a large percentage increase in international prices for iron oxide pellets and lump ores has been agreed between the principal iron ore miners and major steel producers which will affect our costs in the coming quarters. Energy costs are also increasing. Demand for our welded pipe products, which depends to a large extent on specific projects, particularly those for the construction of oil and gas pipelines in the regional market of our two welded pipe mills in South America, and can vary significantly from year to year, is rebounding. There are a number of gas pipeline projects under development in Brazil reflecting investment in the country's gas pipeline infrastructure, and in Argentina there are projects to increase capacity in and extend the existing gas pipeline infrastructure in order to meet growing gas consumption. Assuming no major change in current conditions, we expect our overall 2005 operating margin to remain close to the level registered in this first quarter, which would represent a significant improvement over the level recorded last year. Analysis of 2005 First Quarter Results (metric tons) Sales volume Q1 2005 Q1 2004 Increase/(Decrease) North America 220,000 157,000 40% Europe 179,000 169,000 6% Middle East & Africa 101,000 82,000 23% Far East & Oceania 101,000 114,000 (11%) South America 101,000 96,000 5% Total seamless pipes 703,000 618,000 14% Welded pipes 109,000 69,000 58% Total steel pipes 812,000 687,000 18% Sales volume of seamless pipes increased by 14% to 703,000 tons in the first quarter of 2005 from 618,000 tons in the same period of 2004. This includes 26,000 tons produced by Silcotub. Sales in North America increased in each of Canada, USA and Mexico with the increase strongest in Canada following an increase in drilling of exploration and deep wells. Sales in Middle East and Africa increased due to higher oil and gas drilling activity in the Middle East and a recovery of activity in Nigeria. Sales in Far East and Oceania declined due to lower sales in China. Sales volumes of welded pipes increased by 58% to 109,000 tons in the first quarter of 2005 from 69,000 tons in the same period of 2004. The increase in sales was due to a recovery in demand for welded pipes for gas pipeline projects in Brazil. (US$ million) Net sales Q1 2005 Q1 2004 Increase/(Decrease) Seamless pipes 1,105.3 674.3 64% Welded pipes and other metallic products 160.4 66.4 142% Energy 144.0 103.9 39% Others 43.3 14.8 193% Total 1,452.9 859.3 69% Net sales in the quarter ended March 31, 2005 increased 69% to US$1,452.9 million, compared to US$859.3 million in the corresponding quarter of 2004. Net sales of seamless pipes rose by 64%, due to higher average selling prices, which rose to US$1,572 per ton in the first quarter of 2005 compared to US$1,090 per ton in the same period of 2004, and higher sales volumes. Net sales of welded and other metallic products, which included US$17 million in sales of metal structures made by our Brazilian welded pipe subsidiary in the first quarter of 2005 and US$15 million of such sales in the first quarter of 2004, rose by 142% due to higher sales volume and higher selling prices, which rose to US$1,316 per ton compared to US$745 per ton. Net sales of energy rose by 39% due to higher sales of natural gas and a higher value of the Euro against the US dollar. Net sales of other goods and services increased 193% due to sales of pre-reduced hot briquetted iron from the plant that we acquired in July 2004 and higher sales of sucker rods used in oil extraction. (percentage of net sales) Cost of sales Q1 2005 Q1 2004 Seamless pipes 54% 68% Welded and other metallic products 63% 81% Energy 95% 97% Others 57% 65% Total 60% 72% Cost of sales, expressed as a percentage of net sales, decreased to 60% in the first quarter of 2005, compared to 72% in the same period of 2004. Cost of sales for seamless pipe products, expressed as a percentage of net sales, decreased to 54% in the first quarter of 2005 compared to 68% in the same period of 2004 as higher average selling prices and volume-related efficiencies offset increased raw material costs. Cost of sales for welded and other metallic products, expressed as a percentage of net sales, decreased to 63% in the first quarter of 2005 compared to 81% in the same quarter of 2004 as higher average selling prices and volume-related efficiencies offset increased raw material prices but is not expected to remain at this level. Selling, general and administrative expenses, or SG&A, declined as a percentage of net sales to 12.7% in the quarter ended March 31, 2005 compared to 16.3% in the corresponding quarter of 2004. Net financial expenses rose to US$41.8 million in the first quarter of 2005, compared to net financial expenses of US$15.4 million in the same period of 2004. Net interest expenses increased to US$9.5 million compared to US$5.6 million, reflecting a higher net debt position. However, Tenaris recorded a loss of US$33.9 million on net foreign exchange translations and the fair value of derivative instruments in the first quarter of 2005, compared to a loss of US$15.3 million in the corresponding quarter of 2004. This loss on net foreign exchange translations and the fair value of derivative instruments reflects the application of IFRS and is partially compensated by an increase in our net equity position. Equity in earnings of associated companies generated a gain of US$30.2 million in the first quarter of 2005, compared to a loss of US$0.5 million in the first quarter of 2004. This gain arose mainly in respect of our equity investment in Sidor. Cash Flow and Liquidity Net cash provided by operating activities during the first quarter of 2005 was US$182.7 million. This included a cash inflow of US$66.6 million resulting from the receipt of payment from Fintecna following the arbitration award net of the final instalment on the liability payable to the consortium led by BHP Billiton Petroleum Ltd. which was prepaid during the quarter. Working capital increased by US$209.9 million, due to an increase in inventories of US$91.2 million and a net increase in trade receivables less customer advances and trade payables of US$109.9 million. The increase in inventories is mainly associated with the increase in business activity and includes HBI produced at the Venezuelan plant we began operating in October 2004 and higher welded pipe inventory. Total financial debt decreased by US$133.5 million to US$1,125.8 million at March 31, 2005 from US$1,259.3 million at December 31, 2004. Net financial debt decreased by US$179.4 million to US$648.7 million at March 31, 2005 from US$828.1 million. Some of the statements contained in this press release are "forward-looking statements."
