PITTSBURGH, Pennsylvania -- September 4, 2001 -- The United Steelworkers of America (USWA) called a strike at 12:01 AM Pacific Time on September 4, 2001 at the Wah Chang operation located in Albany, OR. Wah Chang is an Allegheny Technologies Incorporated (NYSE:ATI) company. The strike affects approximately 640 USWA-represented employees. The plant was safely idled prior to the strike.

"It's unfortunate that the United Steelworkers of America chose to take this action," said Lynn D. Davis, president of Wah Chang. "We are disappointed that on August 1 the local union membership failed to ratify the contract which had been agreed upon by the USWA, the company, and the local union leadership. Nevertheless, we were fully prepared to work toward reaching an acceptable agreement when the USWA called this strike. We plan to safely restart the plant within the next few weeks in order to continue meeting the needs of our loyal customers."

The USWA strike does not impact other Allegheny Technologies operations.
