     United States Steel Corporation (NYSE: X) reported second quarter 2005 net
income of $245 million, or $1.88 per diluted share, compared to first quarter
2005 net income of $455 million, or $3.48 per diluted share, and second quarter
2004 net income of $211 million, or $1.62 per diluted share.

     Commenting on results, U. S. Steel President and CEO John P. Surma said,
"Considering global steel market conditions, we had a good quarter with strong
operating results from our European and Tubular segments and a solid performance
by our Flat-rolled segment."

     The company reported second quarter 2005 income from operations of $413
million, compared with income from operations of $640 million in the first
quarter of 2005 and $388 million in the second quarter of 2004.

     Other items not allocated to segments reduced second quarter 2005 net
income by $3 million, or 2 cents per diluted share. First quarter 2005 results
included net income of $58 million, or 45 cents per diluted share, primarily
from a property tax settlement. Second quarter 2004 net income was reduced by
$22 million, or 17 cents per diluted share, primarily resulting from a $33
million charge to net interest and other financial costs for the early
redemption of senior debt.



     Foreign currency losses in the second quarter of 2005 were $43 million,
compared to losses of $27 million and $16 million in the first quarter of 2005
and the second quarter of 2004, respectively. The losses primarily reflect
accounting remeasurement losses from the appreciation of the U.S. dollar
functional currency versus the euro and other local currencies.

     Reportable Segments and Other Businesses
     Management uses segment income from operations to evaluate company
performance because we believe it to be a key measure of ongoing operating
results. U. S. Steel's reportable segments and Other Businesses reported segment
income from operations of $487 million, or $100 per ton, in the second quarter
of 2005, compared with $652 million, or $127 per ton, in the first quarter of
2005 and $454 million, or $82 per ton, in the second quarter of 2004.

     The decrease in second quarter 2005 Flat-rolled income from operations
compared to the first quarter primarily reflected declining spot market prices,
reduced shipments and lower operating levels, with higher outage costs largely
offset by lower raw materials costs. The decline in European operating results
was due mainly to lower sheet spot market prices and higher raw material costs.
Tubular results remained at record levels.

     Outlook
     Commenting on U. S. Steel's outlook, Surma said, "Operating results for the
third quarter of 2005 are likely to be lower than in the second quarter,
reflecting recent spot price trends in domestic and European markets for sheet
products. We have been encouraged by recent reports of lower service center
sheet inventory levels and improved Flat-rolled order entry rates; however,
market conditions will determine if these trends will be sustained throughout
the third quarter and the remainder of the year."

     For Flat-rolled, third quarter 2005 average realized prices are expected to
be moderately lower than in the second quarter, reflecting lower spot prices,
and shipment levels and costs are expected to be comparable to second quarter
levels. The Gary blast furnace project will continue throughout the third
quarter and our remaining domestic production facilities will be operated at
levels necessary to balance our inventories and our order book.

     For U. S. Steel Europe (USSE), third quarter average realized prices are
expected to be significantly lower than in the second quarter, primarily
reflecting the recent decline in hot-rolled spot prices. The price decline
should be partially offset by a significant decrease in raw material costs. The
planned partial reline of the No. 2 blast furnace at U. S. Steel Kosice is
expected to be completed during the third quarter and this furnace will be
restarted when market conditions warrant. Third quarter 2005 shipments for USSE
are expected to be about the same as in the second quarter.

     Shipments and average realized prices for the Tubular segment in the third
quarter of 2005 are expected to be in line with second quarter levels. Tube
round costs will reflect a July 1 increase of $20 per ton to the transfer price
for tube rounds supplied by Flat-rolled because of higher metallic addition
costs.

                                      *****



     This release contains forward-looking statements with respect to market
conditions, operating costs, shipments and prices. Some factors, among others,
that could affect market conditions, costs, shipments and prices for both
domestic operations and USSE include global product demand, prices and mix;
global and company steel production levels; plant operating performance; the
timing and completion of the rebuild of the No. 13 blast furnace at Gary Works
and other facility projects; natural gas and electricity prices and usage; raw
materials availability and prices; 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 and other laws; employee strikes; 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
that may affect USSE's results include, but are not limited to, taxation,
nationalization, inflation, currency fluctuations, increased regulation, 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, 2004, and in subsequent filings for
U. S. Steel.

     A Statement of Operations (Unaudited), Other Financial Data (Unaudited) and
Preliminary Supplemental Statistics (Unaudited) for U. S. Steel are attached.

     The company will conduct a conference call on second quarter earnings on
Tuesday, July 26, at 3 p.m. EDT. To listen to the webcast of the conference
