      PITTSBURGH, October 28, 2008 - United States Steel Corporation (NYSE: X)
reported third quarter 2008 net income of $919 million, or $7.79 per diluted
share, compared to second quarter 2008 net income of $668 million, or $5.65 per
diluted share, and third quarter 2007 net income of $269 million, or $2.27 per
diluted share.



      Commenting on results, U. S. Steel Chairman and CEO John P. Surma said,
"U. S. Steel performed extremely well in the third quarter and recorded the most
profitable quarter in our history. Our Flat-rolled and Tubular segments again
posted record results, and tubular markets especially remained robust throughout
the quarter."

      The company reported third quarter 2008 income from operations of $1,327
million, compared with income from operations of $954 million in the second
quarter of 2008 and $360 million in the third quarter of 2007.

      Other items not allocated to segments in the third quarter of 2008
consisted of a $105 million pre-tax charge for employee signing bonuses paid as
provided in the new labor agreements with the United Steelworkers and a $23
million charge related to environmental remediation at a former production site.
These items reduced net income by $79 million, or 67 cents per diluted share.
Other items not allocated to segments in the second quarter of 2008 consisted of
a charge for inventory transition effects related to the acquisition of U. S.
Steel Canada (USSC) that reduced net income by $4 million, or 3 cents per
diluted share. Discrete charges in the tax provision and an item not allocated
to segments related to the Lone Star acquisition reduced third quarter 2007 net
income by $28 million, or 23 cents per diluted share.

      Net interest and other financial costs in the third quarter of 2008
included a foreign currency loss that decreased net income by $39 million, or 33
cents per diluted share, related to the remeasurement of an $840 million U.S.
dollar-denominated intercompany loan to a European subsidiary, partially offset
by euro-U.S. dollar derivatives activity. This compares to an immaterial effect
for these items in the second quarter of 2008.

      We repurchased 1.13 million shares of common stock for approximately $130
million during the third quarter.



Reportable Segments and Other Businesses

      Management believes segment income from operations is a key measure in
evaluating company performance. U. S. Steel's reportable segments and Other
Businesses reported segment income from operations of $1,461 million, or $227
per ton, in the third quarter of 2008, compared with $959 million, or $136 per
ton, in the second quarter of 2008 and $433 million, or $78 per ton, in the
third quarter of 2007.

      Income from operations for Flat-rolled improved significantly from the
second quarter, primarily reflecting higher average realized prices, partially
offset by increased raw materials costs, decreased shipments and higher costs
for profit sharing.

      The decrease in European operating results was due primarily to higher raw
materials costs, lower shipments due to market conditions and increased costs
resulting from a planned reline of one of our three blast furnaces at U. S.
Steel Kosice that began in early August. These were partially offset by higher
average realized prices.

      Production was reduced late in the third quarter to match declining order
rates for the Flat-rolled and USSE segments. Raw steel production for the
quarter was at 86 percent and 87 percent of capability in North America and
Europe, respectively.

      The substantial increase in Tubular income compared to the second quarter
resulted primarily from higher average realized prices, partially offset by
increased costs for semi-finished steel.

Outlook

      Commenting on U. S. Steel's outlook, Surma said, "The volatile global
economic climate is having significant negative effects on our business and our
forward view is limited because of low order backlogs and short leadtimes. We
expect a decline in fourth quarter results mainly due to softening demand and
prices for flat-rolled products in North America and Europe, and we expect to
continue to operate at reduced production levels, corresponding with customer
order rates."



      For Flat-rolled, fourth quarter results are expected to decrease from the
third quarter due primarily to substantially lower shipments and lower average
realized prices, partially offset by lower raw materials costs.

      Based on very weak market conditions, we expect results to decline
substantially for U. S. Steel Europe (USSE) in the fourth quarter.

      Fourth quarter results for Tubular are currently expected to be comparable
to the third quarter.

                                      *****

      This release contains forward-looking statements with respect to market
conditions, operating costs, shipments and prices. U. S. Steel has been, and we
expect will continue to be, negatively impacted by the current global credit and
economic problems. Other more normal factors that could affect market
conditions, costs, shipments and prices for both North American operations and
USSE include, among others, global product demand, prices and mix; global and
company steel production levels; plant operating performance; the timing and
completion of facility projects; natural gas and electricity prices and usage;
raw materials and transportation prices and availability; the impact of fixed
prices in energy and raw materials contracts (many of which have terms of one
year or longer) as compared to short-term contract and spot prices of steel
products; changes in environmental, tax, pension and other laws; the terms of
collective bargaining agreements; employee strikes or other labor issues; power
outages; and U.S. and global economic performance and political developments.
Domestic steel shipments and prices could be affected by import levels and
actions taken by the U.S. Government and its agencies. Economic conditions and
political factors in Europe and Canada that may affect USSE's and USSC's results
include, but are not limited to, taxation, nationalization, inflation, currency
fluctuations, government instability, political unrest, regulatory changes,
export quotas, tariffs and other protectionist measures. In accordance with
"safe harbor" provisions of the Private Securities Litigation Reform Act of
1995, cautionary statements identifying important factors, but not necessarily
all factors, that could cause actual results to differ materially from those set
forth in the forward-looking statements have been included in the Form 10-K of
U. S. Steel for the year ended December 31, 2007, and in subsequent filings for
U. S. Steel.

      A Statement of Operations (Unaudited), Cash Flow Statement (Unaudited),
Condensed Balance Sheet (Unaudited) and Preliminary Supplemental Statistics
(Unaudited) for U. S. Steel are attached.

      The company will conduct a conference call on third quarter earnings on
Tuesday, October 28, at 2 p.m. EDT. To listen to the webcast of the conference
call, visit the U. S. Steel web site, www.ussteel.com, and click on the
