                      Allegheny Technologies Expects Fourth
           Quarter 2005 Net Special Gain of $0.14 to $0.19 Per Share


     PITTSBURGH--(BUSINESS WIRE)--Jan. 5, 2006--Allegheny Technologies
Incorporated (NYSE:ATI) today announced that it expects to record a fourth
quarter 2005 net special gain of $14.5 to $19.5 million, or $0.14 to $0.19 per
share.
     The fourth quarter 2005 special items, which are primarily non-cash, are
expected to include:

     --   A $38 to $42 million, or $0.37 to $0.41 per share, net tax benefit
          related to the reversal of ATI's remaining valuation allowance for
          Federal net deferred tax assets.

     --   A $14 to $15 million, or ($0.14) to ($0.15) per share, after-tax
          charge due to asset impairments, which is expected to result in future
          cash expenditures of less than $2 million. This asset impairment
          charge primarily relates to a 2005 year-end decision to indefinitely
          idle ATI Allegheny Ludlum's West Leechburg, PA flat-rolled products
          finishing facility. There are approximately 45 hourly production and
          maintenance employees, and 25 laboratory employees at the West
          Leechburg plant. These employees will be provided positions at nearby
          Allegheny Ludlum facilities. ATI expects the consolidation to result
          in annual cost reductions of approximately $10 million in its
          Flat-Rolled Products segment beginning in 2007.

     --   A $6 million, or ($0.06) per share, after-tax charge for legal
          matters.

     --   A $2.5 million, or ($0.02) per share, after-tax charge related to the
          cumulative effect of accounting change for the adoption of FASB
          Interpretation No. 47, "Accounting for Contingent Asset Retirement
          Obligations".

     ATI plans to release fourth quarter 2005 earnings on January 25, 2006.
