CIRCOR’s Leslie Controls Subsidiary Emerges from

Chapter 11 Reorganization

Funding of 524(g) Asbestos Trust Marks Formal Completion of Bankruptcy Process

Burlington, MA – April 28, 2011 – CIRCOR International, Inc. (NYSE: CIR) today announced that the company and its wholly owned subsidiary, Leslie Controls, Inc. have funded the Section 524(g) asbestos trust established under Leslie’s Chapter 11 reorganization plan affirmed in February 2011 by the U.S. District Court for the District of Delaware.

With the funding of the trust, Leslie has now emerged from Chapter 11 protection. Leslie initially filed a pre-negotiated plan of reorganization under Chapter 11 of the U.S. Bankruptcy Code in July 2010 to permanently resolve its asbestos liability.

“The funding of the trust and the completion of this process is a tremendous accomplishment for CIRCOR, our shareholders and our employees,” said CIRCOR Chairman, President and Chief Executive Officer Bill Higgins. “With Leslie’s emergence from Chapter 11 reorganization, we can focus our full attention on executing our growth strategy and further enhancing value for our shareholders.”
