    Allegheny Technologies Employees at Certain Operations Ratify New Labor
                                   Agreements

    PITTSBURGH--(BUSINESS WIRE)--March 5, 2007--Allegheny Technologies
Incorporated (NYSE:ATI) announced today that the United Steelworkers
(USW) represented employees at the Company's ATI Allegheny Ludlum and
ATI Albany, OR titanium operations ratified new four-year labor
agreements. The new agreements expire on June 30, 2011, and succeed
existing contracts that run through June 30, 2007.

    "We are pleased with the outcome of the ratification vote," said
Patrick Hassey, Chairman, President and Chief Executive Officer of
Allegheny Technologies. "The agreements are fair and balanced for both
the Company and the affected employees. Ratification of new agreements
months before the old agreements were due to expire allows ATI to
continue a reliable supply of specialty metals to our customers from
our Allegheny Ludlum and Albany, OR operations during very good market
conditions.

    "Importantly, these labor agreements maintain the new work
environment that began at Allegheny Ludlum with the implementation of
our progressive labor agreement in 2004. Allegheny Ludlum's cost
structure continues to be competitive and employees receive a good
compensation package."

    Highlights of the agreements include:

    --  Wage and benefit increases that are in line with anticipated
        inflation.

    --  The Allegheny Ludlum contract provides for profit sharing
        above a specified minimum pre-tax profit at the Allegheny
        Ludlum operations, and is capped to provide for no more than
        $20 million of profit sharing payments over the 4-year life of
        the contract. Any profit sharing payments made under this
        provision are contributed to an independently administered
        VEBA (Voluntary Employee Benefit Arrangement) trust.

    --  The cap on post-retirement benefits (OPEB) negotiated as part
        of the previous contracts remains in effect.

    As a result of the new agreements, ATI expects to record a
non-recurring after-tax special charge of approximately $4 million, or
$0.04 per share, in the first quarter 2007.
