Pittsburgh, PA, June 1, 2009 — Allegheny Technologies Incorporated (NYSE:ATI) announced today that it has completed its previously announced public offering of senior notes due 2019.

As of today, there were $300 million in aggregate principal amount of 8.375% Notes outstanding. Any net proceeds from the offering of Senior Notes not used to purchase the 8.375% Notes will be used for general corporate purposes.

Citi and J.P. Morgan Securities Inc. were the joint book-running managers for the offering.

This press release does not constitute an offer to sell or the solicitation of an offer to buy, nor shall there be any sale of any Senior Notes in any jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such jurisdiction. A registration statement relating to the Senior Notes has been filed with the Securities and Exchange Commission.

ATI’s obligation to accept any 8.375% Notes due 2011 tendered in its tender offer and to pay the applicable consideration for them are set forth solely in the related Offer to Purchase and the Letter of Transmittal.

The Company also announced that it has amended certain definitions and financial covenants in its $400 million senior unsecured domestic revolving credit facility to provide additional financial flexibility. The amendment restates the definition of consolidated earnings before interest and taxes and consolidated earnings before income, taxes, depreciation and amortization as used in the interest coverage and leverage ratios to exclude any non-cash pension expense or income and restates the definition of consolidated indebtedness used in the leverage ratio, which previously was based on gross indebtedness, to be net of cash on hand in excess of $50 million.
