Allegheny Technologies Announces Pricing of Concurrent Senior Notes and
Convertible Notes Offerings

Pittsburgh, PA — May 27, 2009 — Allegheny Technologies Incorporated (NYSE:ATI) announced today that it has priced its concurrent public offerings of senior notes due 2019 and convertible notes due 2014. The offerings are being made pursuant to the Company’s shelf registration statement filed with the Securities and Exchange Commission. Neither the completion of the senior notes offering nor the convertible notes offering will be contingent on the completion of the other.

ATI announced that it has agreed to sell $350,000,000 aggregate principal amount of 9.375% Senior Notes due 2019 (the “Senior Notes”). ATI previously had announced an intention to sell $300,000,000 of Senior Notes. The Senior Notes will pay interest semi-annually in arrears at a rate of 9.375% per year and will mature on June 1, 2019, unless earlier repurchased. ATI intends to use the net proceeds from the offering of the Senior Notes to purchase any and all of its outstanding 8.375% Notes due 2011 (the “8.375% Notes”) pursuant to the terms of a tender offer by ATI for those 8.375% Notes. 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.

ATI also announced the pricing of its offering of $350,000,000 aggregate principal amount of 4.25% Convertible Senior Notes due 2014 (the “Convertible Notes”). ATI has granted the underwriters a 30-day option to purchase up to an additional $52,500,000 aggregate principal amount of the Convertible Notes on the same terms and conditions to cover over-allotments, if any. The Convertible Notes will pay interest semi-annually in arrears at a rate of 4.25% per year and will mature on June 1, 2014, unless earlier repurchased or converted. Holders may convert their Convertible Notes into shares of ATI’s common stock at their option any time prior to the close of business on the second scheduled trading day immediately preceding the maturity date. The conversion rate will initially be 23.9263 shares of common stock per $1,000 principal amount of Convertible Notes (representing an initial conversion price of approximately $41.80 per share of common stock), subject to adjustment in certain circumstances. ATI intends to use the net proceeds from the offering of Convertible Notes to manage its liabilities and other obligations, such as by making voluntary contributions to its defined benefit pension trust and contributions to trusts established to fund retiree medical benefits, and the balance for general corporate purposes.
