Allegheny Technologies Updates Fourth Quarter 2009 Outlook

PITTSBURGH--(BUSINESS WIRE)--December 17, 2009--Allegheny Technologies Incorporated (NYSE:ATI) expects fourth quarter 2009 earnings to be in the range of $0.20 to $0.25 per share. ATI had previously said that it expected fourth quarter 2009 earnings to be similar to the $0.01 per share earned in the third quarter 2009.

“ATI will be profitable in 2009,” said L. Patrick Hassey, Chairman, President and Chief Executive Officer. “Each of our three segments is seeing some improvement. Fourth quarter 2009 performance is benefiting from better volume, pricing, and mix for certain products, lower raw materials costs, and our improved cost structure. In addition, we have been growing our position with key customers, and we are expanding our product, market, and global diversification.”

ATI plans to release fourth quarter and full-year 2009 earnings on January 27, 2010, before the market opens. ATI will provide live Internet listening access to its conference call with investors and analysts at 1 p.m. ET on January 27, 2010. The conference call will be broadcast at www.alleghehenytechnologies.com.
