Tenaris Announces 2007 Third Quarter Results

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.

LUXEMBOURG, Nov. 7, 2007 - Tenaris S.A. (NYSE, Buenos Aires and Mexico: TS and
MTA Italy: TEN) ("Tenaris") today announced its results for the quarter and nine
months ended September 30, 2007 with comparison to its results for the quarter
and nine months ended September 30, 2006.

Summary of 2007 Third Quarter Results

(Comparison with second quarter of 2007 and third quarter of 2006)

                                       Q3 2007        Q2 2007         Q3 2006
Net sales (US$ million)                2,523.6   2,604.2   (3%)   1,803.6    40%
Operating income (US$ million)           687.3     780.4  (12%)     692.8   (1%)
Net income (US$ million)                 436.4     534.5  (18%)     510.0  (14%)
Shareholders' net income (US$ million)   401.0     496.0  (19%)     479.1  (16%)
Earnings per ADS (US$)                    0.68      0.84  (19%)      0.81  (16%)
Earnings per share (US$)                  0.34      0.42  (19%)      0.41  (16%)
EBITDA (US$ million)                     828.2     910.7   (9%)     749.0    11%
EBITDA margin (% of net sales)             33%       35%              42%

Our results in the third quarter were affected by a lower level of sales of
seamless pipe products and higher production costs. On a comparable basis, sales
of API-grade products were lower year on year in the Middle East, following the
inventory build-up that took place last year, as well as in Canada. Although net
sales were up 40% year on year, operating income was flat and earnings per share
were down. Sales are expected to recover only partially in the fourth quarter
before growing again in the first half of 2008. Free cash flow (net cash
provided by operations less capital expenditures) rose to US$784.3 million, and
net financial debt (total financial debt less cash and other current
investments) declined by US$718.2 million to US$3,043.5 million at September 30,
2007.

Payment of Interim Dividend

Tenaris's board of directors approved the payment of an interim dividend of
US$0.13 per share (US$0.26 per ADS), or approximately US$153 million, on
November 22, 2007, with an ex-dividend date of November 19.



Market Background and Outlook

After fluctuating in the first quarter of 2007, oil prices have resumed the
upwards trend shown in the previous three years as global demand projections
have been revised upwards and geopolitical tensions have risen in the Middle
East. On the other hand, North American gas prices, which fell sharply from the
highs reached in the first half of 2006, have fluctuated at lower levels for
most of the year to date as the amount of gas in storage has remained at the
higher end of its seasonal range. The international count of active drilling
rigs, as published by Baker Hughes, continues to rise and averaged 1020 during
the third quarter, an increase of 2% over the previous quarter and one of 8%
compared to the same quarter of the previous year. In Canada, however, where
drilling activity is sensitive to North American gas prices and drilling costs
have been rising in U.S. dollar terms, the rig count registered a 30% decline in
the third quarter of 2007 compared to the same quarter of 2006, and is now down
29% for the first nine months of 2007 compared to the same period of 2006. The
U.S. rig count remained stable showing a 2% increase during the third quarter of
2007 compared to the second quarter of 2007 and was up 4% compared to the third
quarter of 2006.

Although a recovery in Canadian drilling activity remains uncertain, drilling
activity in the rest of the world is firm as oil and gas prices encourage
operators to continue increasing investments in exploration and production
activity. However, in North America demand for OCTG products in 2007 has been
affected by distributor inventory destocking which could continue until the end
of the year. In the Middle East, apparent consumption of OCTG products is, and
is likely to remain, lower in the second half of this year.

Steelmaking raw material and energy costs have risen in 2007 and look set to
rise further in 2008. Labor costs have also been rising primarily due to
currency-related factors. In the first half of 2007, cost increases and price
declines for some of our products were offset by improvements in product mix.
However, in the third quarter, our operating margins declined as production
costs continued to rise and we had a less favorable product mix. Our operating
margins are likely to remain under pressure for the rest of the year before
recovering in the first half of 2008 when we expect increased sales of our
specialized, high-end products.

Sales of our pipes for pipeline projects in South America picked up at the end
of the first quarter of 2007 as we commenced deliveries to the GASCAC phase of
the GASENE project in Brazil. Sales in this segment are expected to remain
strong during the remainder of 2007 and into 2008 as we make deliveries to this
and other projects in the region.

Analysis of 2007 Third Quarter Results

  Sales volume (metric tons)      Q3 2007       Q3 2006      Increase/(Decrease)

Tubes - Seamless                  659,000       709,000            (7%)

        Tubes                     Q3 2007       Q3 2006      Increase/(Decrease)
(Net sales - $ million)
North America                       744.1         368.2            102%
South America                       310.6         258.2             20%

Middle East & Africa                471.7         477.4            (1%)
Far East & Oceania                  175.9         175.1              0%
Total net sales ($ million)       2,062.6       1,595.0             29%

Operating income (% of sales)         30%           41%

Net sales of tubular products and services rose 29% to US$2,062.6 million in the
third quarter of 2007, compared to US$1,595.0 million in the third quarter of
2006, due primarily to the incorporation of sales from the former Maverick and
Hydril operations. On a like for like basis, average selling prices rose largely
due to product mix improvements but sales volumes declined reflecting lower
demand principally in the Middle East and Canada. In North America, sales were
affected by the decline in drilling activity in Canada, but sales of OCTG
products increased in Mexico. In South America, sales benefited from a recovery
in demand for OCTG products in Venezuela. In the Middle East and Africa, higher
sales on specialized, high-end products were offset by lower sales of API
products.


       Projects                   Q3 2007       Q3 2006      Increase/(Decrease)

Net sales ($ million)               235.6          80.1            194%
Cost of sales (% of sales)            72%           78%
Operating income ($ million)         42.0           1.7
Operating income (% of sales)         18%            2%

Net sales of pipes for pipeline projects increased 194% to US$235.6 million in
the third quarter of 2007, compared to US$80.1 million in the third quarter of
2006, reflecting higher sales in Brazil where we continued deliveries for the
GASCAC phase of the GASENE project and in Argentina where we made some
deliveries for the delayed Loops project.

   Pressure Control               Q3 2007

Net sales ($ million)                89.8
Cost of sales (% of sales)            68%
Operating income ($ million)         15.6
Operating income (% of sales)         17%

Net sales of pressure control products amounted to US$89.8 million in this first
complete quarter since we acquired the business. This compares to US$49.2
million in the two months reported in the second quarter of 2007.



      Others                      Q3 2007       Q3 2006      Increase/(Decrease)
Net sales ($ million)               135.6         128.6              5%
Cost of sales (% of sales)            73%           63%
Operating income ($ million)         14.2          30.4            (53%)
Operating income (% of sales)         10%           24%

Net sales of other products and services rose 5% to US$135.6 million in the
third quarter of 2007, compared to US$128.6 million in the third quarter of
2006.

Selling, general and administrative expenses, or SG&A, increased as a percentage
of net sales to 15.9% in the quarter ended September 30, 2007 compared to 13.5%
in the corresponding quarter of 2006 due primarily to an increase in
amortization expenses following the incorporation of Maverick and Hydril.
Amortization of customer relationships and other intangibles acquired with
Maverick and Hydril amounted to US$64 million in the quarter, or 2.5% of net
sales.

Net interest expenses rose to US$57.1 million in the third quarter of 2007
compared to net interest income of US$2.2 million in the same period of 2006
reflecting an increased net debt position following the Maverick and Hydril
acquisitions.

Other financial results recorded a loss of US$12.9 million during the third
quarter of 2007, compared to a loss of US$6.5 million during the third quarter
of 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$18.3 million
in the third quarter of 2007, compared to a gain of US$29.7 million in the third
quarter of 2006. These gains were derived mainly from our equity investment in
Ternium.

Income tax charges totalled US$199.2 million in the third quarter of 2007,
equivalent to 32% of income before equity in earnings of associated companies
and income tax, compared to US$210.5 million in the third quarter of 2006,
equivalent to 31% of income before equity in earnings of associated companies
and income tax.

Income attributable to minority interest rose to US$35.4 million in the third
quarter of 2007, compared to US$30.9 million in the corresponding quarter of
2006 primarily reflecting higher operating and financial results at our Confab
subsidiary.

Cash Flow and Liquidity

Net cash provided by operations during the third quarter of 2007 was US$889.8
million (US$1,789.1 million in the first nine months), compared to US$598.1
million in the third quarter of 2006 (US$1,312.2 million in the first nine
months). Working capital decreased by US$220.0 million during the third quarter
reflecting a decrease in trade receivables and an increase in customer advances.



Capital expenditures amounted to US$105.4 million in the third quarter of 2007
(US$334.6 million in the first nine months), compared to US$133.0 million in the
third quarter of 2006 (US$302.1 million in the first nine months).

During the first nine months of 2007, total financial debt increased by
US$1,258.5 million to US$4,909.7 million at September 30, 2007 from US$3,651.2
million at December 31, 2006. Net financial debt during the first nine months of
2007 increased by US$948.2 million to US$3,043.5 million at September 30, 2007
following the acquisition of Hydril for a total consideration of $2.0 billion.

Analysis of 2007 First Nine Months Results

Net income attributable to equity holders in the company during the first nine
months of 2007 was US$1,377.2 million, or US$1.17 per share (US$2.33 per ADS),
which compares with net income attributable to equity holders in the company
during the first nine months of 2006 of US$1,370.6 million, or US$1.16 per share
(US$2.32 per ADS). Operating income was US$2,225.3 million, or 29% of net sales,
compared to US$1,979.9 million, or 38% of net sales. Operating income plus
depreciation and amortization was US$2,597.0 million, or 34% of net sales,
compared to US$2,146.0 million, or 41% of net sales.

Net sales of tubular products and services rose 36% to US$6,399.7 million in the
first nine months of 2007, compared to US$4,694.4 million in the first nine
months of 2006, due primarily to the incorporation of sales from the former
Maverick and Hydril operations. On a like for like basis, average selling prices
increased due largely to product mix improvements and volumes registered a
marginal decrease.

Net sales of other products and services rose 56% to US$453.5 million in the
first nine months of 2007, compared to US$291.4 million in the first nine months
of 2006, primarily reflecting the inclusion of sales of conduit pipes.

Selling, general and administrative expenses, or SG&A, increased as a percentage

acquisitions.

Other financial results recorded a loss of US$10.8 million during the first nine

months of 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$73.6 million
