  Allegheny Technologies Announces New Premium-Grade Titanium Sponge Facility

    PITTSBURGH--(BUSINESS WIRE)--June 26, 2006--Allegheny Technologies
Incorporated (NYSE:ATI) announced today that its Board of Directors
has approved a greenfield premium-grade titanium sponge facility to be
built in Rowley, UT with an annual capacity of 24 million pounds. This
$325 million investment is aimed at increasing ATI's capacity to
produce titanium alloys for aerospace and defense applications.
Premium-grade sponge is essential for many aerospace applications,
including rotating quality titanium alloys used for new jet engines
and spare parts. ATI expects initial production to begin in the third
quarter 2008.
    This Phase IV titanium expansion brings ATI's projected total
annual titanium sponge capacity to approximately 40 million pounds.
ATI previously announced three titanium sponge capacity increases at
its Albany, OR facility amounting to 16 million pounds per year.
    "ATI's 40 million pounds of annual titanium sponge capacity
provides opportunities for significant revenue and earnings growth and
a stable low-cost supply of this vital raw material. Strategically
securing a cost-competitive source of titanium sponge is critical to
achieving our profitable growth potential. The expected return on this
investment is very attractive," said Patrick Hassey, Chairman,
President and Chief Executive Officer of Allegheny Technologies. "With
this additional titanium sponge raw material supply, we can
confidently meet the growing long-term mill product demand from our
customers. We also plan to continue to purchase titanium units in the
form of sponge and scrap from our long-term suppliers."
    The Board's approval of the Phase IV expansion is contingent upon
the satisfactory completion of appropriate arrangements relating to
the acquisition of and use of property, incentives from the State of
Utah and the County of Tooele, and the supply of raw materials and
utilities.
    "Looking to the later part of this decade, our customers' forecast
demand for titanium mill products exceeds the titanium industry's
current and announced production capacity," Hassey said. "ATI is
investing to grow profitably and rapidly with this robust demand. ATI
is uniquely positioned to grow in the global titanium market with our
expanding titanium raw material supply and unequalled melt
capabilities. In addition, we have an unparalleled combination of
assets for finishing titanium products."
    ATI previously announced a $150 million three-phase titanium
products expansion that is expected to yield 16 million pounds of
titanium sponge capacity and increase ATI's annual titanium melt
capacity by approximately 25 million pounds:
