Allegheny Technologies Announces Further Expansion of its Titanium Capabilities

    PITTSBURGH--(BUSINESS WIRE)--Feb. 23, 2007--Allegheny Technologies
Incorporated (NYSE:ATI) announced that its Board of Directors has
approved a further expansion of the titanium sponge production
capabilities at ATI's Albany, OR facility. The purpose of the capital
project is to meet growing demand from the aerospace and defense,
chemical process, and oil and gas markets. This investment of
approximately $38 million is designed to add 4 million pounds of
titanium sponge capacity to the Albany, OR facility, which brings the
annual production capacity at that facility to 20 million pounds. ATI
expects this self-funded project to be substantially completed by the
second quarter 2008.

    ATI also updated the progress of its previously announced
greenfield premium titanium sponge facility planned for Rowley, UT.
This new facility is now being designed to facilitate expansion beyond
the 24 million pounds of annual titanium sponge capacity originally
planned. As a result of this and other design improvements, the
investment in this facility is now estimated to be between $425 and
$450 million. The Rowley, UT facility is expected to begin operation
in late 2008 and reach the 24 million pound annual production rate by
the second half 2009.

    The further expansion at ATI's Albany, OR facility plus the
Rowley, UT facility project bring ATI's total annual internal titanium
sponge production capacity to at least 44 million pounds by the end of
2009.

    "The opportunities to grow our titanium mill product shipments are
significant, and continue to increase. As a result, we decided to move
forward with the further expansion of our Albany, OR titanium sponge
facility and position the Rowley, UT facility for future expansion,"
said Patrick Hassey, Chairman, President and Chief Executive Officer.
"ATI's planned titanium sponge capacity provides a stable low-cost
supply of this vital raw material that is strategic to achieving our
growth potential. The projected return on these investments is very
attractive.

    "During the last few months, we announced the two largest
long-term agreements (LTAs) in the history of ATI. Both LTAs are with
premiere aerospace companies who require growing and significant
amounts of titanium mill products.

    "In addition, demand for our titanium mill products is growing
rapidly from the chemical process and oil and gas markets. For
example, demand is expected to remain strong for titanium products
used in the manufacture of fertilizers. Demand is also expected to
remain strong for titanium products needed for heat exchangers used in
liquefied natural gas (LNG) and other oil and gas applications."

    This latest Albany, OR expansion project includes four new
reduction and distillation furnaces as well as auxiliary equipment.
The first furnace start up is planned for early 2008. The other
furnaces begin production in subsequent months, and the fourth furnace
start up is scheduled for the later part of the second quarter 2008.

    ATI now expects total capital investments to be in the range of
$450 to $500 million in 2007.
