Exhibit 99.1


Jury Finds Against Allegheny Technologies Subsidiary in San Diego Lease Dispute

    PITTSBURGH--(BUSINESS WIRE)--March 11, 2004--Allegheny
Technologies Incorporated (NYSE:ATI) announced an unfavorable jury
verdict in litigation between TDY Industries, Inc., an ATI subsidiary,
and the San Diego Unified Port District concerning a lease of property
located in San Diego, CA. The jury found in favor of and awarded
damages to the Port District. As a result, when ATI files its 2003
Report on Form 10-K on March 15, 2004, ATI's 2003 results will reflect
a charge of $22.5 million, which includes the jury award and related
costs. The company plans to appeal this verdict.
    TDY Industries' Ryan Aeronautical division had operated at the
facility until May 1999, when substantially all of Ryan's business and
assets were sold. TDY Industries commenced the suit against the Port
District relating to the Port District's failure to consent to
subleases of the property. The Port District filed a cross-complaint,
alleging breach of contract for failure to pay rent, as well as breach
relating to removal of structures from the property. The jury found in
favor of the Port District on its claim.
    "We are very surprised and disappointed with the verdict and will
be taking action to have the verdict overturned," said Jon Walton,
Executive Vice President Chief Legal and Compliance Officer and
General Counsel of Allegheny Technologies.
