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/
                                           FY 2007     FY 2006  (Decrease)
Net sales (US$ million)                   10,042.0     7,727.7      30%
Operating income (US$ million)             2,957.2     2,792.5       6%
Net income (US$ million)                   2,076.1     2,059.4       1%
Shareholders' net income (US$ million)     1,923.7     1,945.3      (1%)
Earnings per ADS (US$)                        3.26        3.30      (1%)
Earnings per share (US$)                      1.63        1.65      (1%)
EBITDA (US$ million)                       3,449.3     3,045.6      13%
EBITDA margin (% of net sales)                  34%         39%

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.
