            Tenaris Announces 2007 Second 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--(BUSINESS WIRE)--Aug. 3, 2007--Tenaris S.A.
(NYSE:TS)(BI:TEN)(BMV:TS)(BCBA:TS) ("Tenaris") today announced its
results for the quarter and semester ended June 30, 2007 with
comparison to its results for the quarter and semester ended June 30,
2006.

    Summary of 2007 Second Quarter Results

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




                               --------   ------------   -------------
                               Q2 2007      Q1 2007         Q2 2006
                               --------   ------------   -------------
Net sales (US$ million)         2,604.2   2,425.3   7%   1,841.3   41%

 sales)                             35%       35%            40%


    Our results in the second quarter continue to reflect a solid
operating performance. Net sales were up 41%, operating income up 13%
and earnings per share up 5% year on year, as a positive operating
environment in the rest of the world offset a sharp decline in
drilling activity in Canada. We continue to make progress in
integrating our North American operations and positioning our
commercial offer with its full range of products. Free cash flow (net
cash provided by operations less capital expenditures) totaled
US$101.9 million, and net financial debt (total financial debt less
cash and other current investments) increased to US$3,761.7 million at
June 30, 2007 following the Hydril acquisition and payment of an
annual dividend.

    Appointment of Chief Financial Officer

    Carlos Condorelli, who was recently elected to serve as a member
of our Board of Directors, will retire from his position as our Chief
Financial Officer as of September 30, 2007. He will continue to serve
as an advisor to Paolo Rocca, our Chairman and CEO. Ricardo Soler, who
served as Executive Vice-President of Confab, our Brazilian welded
pipe subsidiary, until November 2006 and is currently serving as CEO
of our recently acquired Hydril subsidiary, will be our new CFO. As
our CFO since inception as a publicly listed company in 2002, Carlos
Condorelli has played a key role in the growth of Tenaris overseeing
the exchange offer through which Tenaris was consolidated into a
single, global enterprise as well as the subsequent expansion of the
Company into Eastern Europe and North America.

    Consolidation of Hydril

    These second quarter results include the consolidation of Hydril's
results of operations and financial condition beginning in May.
Hydril's premium connection business has been included in our Tubes
segment and a new segment has been created for Hydril's pressure
control business.

    Market Background and Outlook

    After fluctuating in the first quarter, oil prices have resumed
the upwards trend shown in the past three years as global demand
projections have been revised upwards. On the other hand, North
American gas prices, which had shown signs of recovery in the first
half of 2007 have been falling again as the level of gas in storage
has risen to the higher end of the seasonal range. The international
count of active drilling rigs, as published by Baker Hughes, continued
to rise and averaged 1002 during the second quarter, an increase of 2%
over the previous quarter and one of 10% compared to the same quarter
of the previous year. In North America, however, where drilling
activity is more sensitive to regional gas prices, the Canadian rig
count, in addition to showing its customary seasonal weakness,
registered a 51% decline in the second quarter of 2007 compared to the
same quarter of 2006. The U.S. rig count remained stable showing a 1%
increase during the second quarter of 2007 compared to the first
quarter of 2007 and was up 8% compared to the second quarter of 2006.

    The decline in the Canadian rig count was to a level last seen in
2002 and was concentrated in Western Canadian gas drilling. With North
American gas prices continuing to fall, any recovery in Canadian
drilling activity in the second half of the year is likely to be
limited. Demand in the rest of the world, however, remains firm as oil
and gas operators continue to increase investments in exploration and
production activity.

    The costs of our steelmaking raw materials and energy have risen
in the year to date and these cost increases will be more fully
reflected in our results for the second half. However, continuing
improvements in our product mix should offset the impact of higher
costs and the normal seasonal decline in seamless pipe sales volumes
in the third quarter on our operating margins in the second half.

    Sales of our pipes for pipeline projects in South America picked
up at the end of the first quarter as we commenced deliveries to the
GASCAC phase of the GASENE project in Brazil. Sales are expected to
remain strong during the rest of the year as we complete deliveries to
this and other projects in Brazil.

Operating income (% of sales)       33%       41%


    Net sales of tubular products and services rose 33% to US$2,192.3
million in the second quarter of 2007, compared to US$1,651.4 million
in the second 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. In North America, sales were affected by a sharp decline
in drilling activity in Canada, but sales of OCTG products rose in
Mexico reflecting a moderate increase in oil and gas drilling
activity. In South America, sales benefited from a recovery in demand
in Venezuela. In the Middle East and Africa, sales of premium
connection and other specialized products increased but demand for API
products was lower in some markets following a build up of stocks in
2006. In Europe, sales increased primarily due to an increase in
average selling prices.

    Net sales of pipes for pipeline projects increased 92% to US$200.8
million in the second quarter of 2007, compared to US$104.8 million in
the second quarter of 2006, reflecting higher sales in Brazil where
deliveries for the GASCAC phase of the GASENE project which commenced
at the end of the first quarter continued during the period.

         Pressure Control                        Q2 2007
-----------------------------------     --------------------------
Net sales (US$ million)                                       49.2
Cost of sales (% of sales)                                     61%

    Net sales of pressure control products amounted to US$49.2 million
in the two months since we acquired this business from Hydril. The
business has a good backlog of orders and sales are expected to remain
strong into 2009.




------------------------------   -------  -------  -------------------
            Others               Q2 2007  Q2 2006  Increase/(Decrease)
------------------------------   -------  -------  -------------------
Net sales (US$ million)            161.8     85.2                  90%
Cost of sales (% of sales)           79%      74%
Operating income (US$ million)      13.4      2.3                 484%
Operating income (% of sales)         8%       3%


    Net sales of other products and services rose 90% to US$161.8
million in the second quarter of 2007, compared to US$85.2 million in
the second quarter of 2006, reflecting the inclusion of sales of
conduit pipes.

    Selling, general and administrative expenses, or SG&A, increased
as a percentage of net sales to 15.7% in the quarter ended June 30,
2007 compared to 13.4% 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$58 million in the quarter, of which US$19 million
corresponded to Hydril.

    Other income and expenses included an expense of US$10.3 million
relating to the settlement of outstanding redemptions on Maverick's
2005 notes.

    Net interest expenses rose to US$47.8 million in the second
quarter of 2007 compared to US$1.2 million in the same period of 2006
reflecting an increased net debt position following the Maverick and
Hydril acquisitions.

    Other financial results recorded a gain of US$15.1 million during
the second quarter of 2007, compared to a gain of US$5.4 million
during the second 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$29.4 million in the second quarter of 2007, compared to a gain of
US$25.6 million in the second quarter of 2006. These gains were
derived mainly from our equity investment in Ternium.

    Income tax charges totaled US$242.7 million in the second quarter
of 2007, equivalent to 32% of income before equity in earnings of
associated companies and income tax, compared to US$225.7 million in
the second quarter of 2006, equivalent to 33% of income before equity
in earnings of associated companies and income tax.

    Income attributable to minority interest rose to US$38.5 million
in the second quarter of 2007, compared to US$24.0 million in the
corresponding quarter of 2006 reflecting higher operating and
financial results at our Confab and NKKTubes subsidiaries.

    Cash Flow and Liquidity

    Net cash provided by operations during the second quarter of 2007
was US$211.1 million (US$899.4 million in the first half), compared to
US$170.0 million in the second quarter of 2006 (US$714.1 million in
the first half). Cash flow in the second quarter is affected by the
concentration of income tax payments made in this quarter. Working
capital increased by US$34.8 million during the second quarter
principally in our Projects segment.

    Capital expenditures amounted to US$109.2 million in the second
quarter of 2007 ($229.1 million in the first half), compared to
US$99.6 million in the second quarter of 2006 (US$169.1 million in the
first half). These expenditures reflect the progress of implementation
of our two-year investment program to increase capacity for
specialized products. During this second quarter of 2007 we completed
construction of new heat treatment plants in Mexico and Argentina.

    During the first half of 2007, total financial debt increased by
US$1,171.0 million to US$4,822.3 million at June 30, 2007 from
US$3,651.2 million at December 31, 2006. Net financial debt during the
first half of 2007 increased by US$1,666.4 million to US$3,761.7
million at June 30, 2007 following the acquisition of Hydril for a
total consideration of $2.0 billion and the payment of $354 million as
an annual dividend in June 2007.

    Analysis of 2007 First Half Results

    Net income attributable to equity holders in the company during
the first semester of 2007 was US$976.3 million, or US$0.83 per share
(US$1.65 per ADS), which compares with net income attributable to
equity holders in the company during the first semester of 2006 of
US$891.5 million, or US$0.76 per share (US$1.51 per ADS). Operating
income was US$1,538.0 million, or 31% of net sales, compared to
US$1,287.2 million, or 37% of net sales. Operating income plus
depreciation and amortization was US$1,768.8 million, or 35% of net
sales, compared to US$1,397.0 million, or 40% of net sales.

    Net sales of tubular products and services rose 40% to US$4,337.1
million in the first half of 2007, compared to US$3,099.4 million in
the first half 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 increase.

as a percentage of net sales to 15.6% in the semester ended June 30,
2007 compared to 13.4% in the corresponding semester 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$95 million in the semester, of which US$19 million
corresponded to Hydril.

    Net interest expenses rose to US$83.3 million in the first half of
2007 compared to US$0.5 million in the same period of 2006 reflecting
an increased net debt position following the Maverick and Hydril
acquisitions.

    Other financial results recorded a gain of US$2.1 million during
the first half of 2007, compared to a gain of US$15.1 million during
the first half 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$55.3 million in the first half of 2007, compared to a gain of
US$47.1 million in the first half of 2006. These gains were derived
mainly from our equity investment in Ternium.

    Income tax charges totaled US$468.2 million in the first half of
2007, equivalent to 32% of income before equity in earnings of
associated companies and income tax, compared to US$415.8 million in
the first half of 2006, equivalent to 32% of income before equity in
earnings of associated companies and income tax.

    Income attributable to minority interest rose to US$67.6 million
in the first half of 2007, compared to US$46.0 million in the
corresponding semester of 2006 reflecting higher operating and
financial results at our Confab and NKKTubes subsidiaries.
