  Allegheny Technologies Expects Strong Fourth Quarter 2004 Results


    PITTSBURGH--(BUSINESS WIRE)--Jan. 18, 2005--Allegheny Technologies
Incorporated (NYSE:ATI) said today that it expects fourth quarter 2004
earnings to be in the range of $0.32 to $0.37 per share. The Company
plans to release its fourth quarter and full-year 2004 results before
the market opens on January 31, 2005.
    "Our projected fourth quarter 2004 results are due primarily to
better than expected operating results in our Flat-Rolled Products and
High Performance Metals segments," said Pat Hassey, Chairman,
President and Chief Executive Officer of Allegheny Technologies.
"Fourth quarter 2004 results benefited from operating efficiencies and
cost reductions, which were enhanced by the successful integration of
this past summer's stainless steel asset acquisition and our upgraded
high performance metals rolling mill. The fourth quarter 2004 results
include a LIFO inventory valuation reserve charge of approximately $30
million due to higher raw materials costs. Looking ahead, we continue
to be optimistic about 2005."
    ATI plans to provide more information on its fourth quarter 2004
earnings and its outlook for 2005 in the Company's earnings news
release. ATI will provide live Internet listening access to its
conference call scheduled for January 31, 2005, at 1 p.m. ET. The
conference call will be broadcast at www.alleghenytechnologies.com.
