CHASKA, Minn.--(BUSINESS WIRE)--Nov. 29, 2005--Entegris, Inc. (Nasdaq:ENTG), a global leader in materials integrity management, announced today it will close its manufacturing plant in Bad Rappenau, Germany, and will relocate the production of products made in that plant to other existing company sites in the U.S. and Asia.

Gideon Argov, Entegris president and chief executive officer, said, "The realignment of our European manufacturing operation, while separate from the integration activities relating to our August 6, 2005 merger with Mykrolis Corporation, reflects our ongoing efforts to increase our operating efficiencies worldwide."

The company expects the realignment will result in out-of-pocket expenses of approximately $3.5 million, and asset write-offs of about $3.0 million. Once completed, the move is expected to yield approximately $2.0 million in annualized savings. The 44,000 square foot facility in Bad Rappenau currently employs approximately 100 employees.
