July 28, 2006 – Seeing an opportunity to help fund future growth, Cymer Inc. said it plans to repurchase up to $150 million of its common stock, on both the open market and in private transactions.

The program, which the company says will be discontinued at any time, represents about 10% of total market value for the light source vendor, which has approximately 41.2 million shares outstanding, at a closing value on July 28 of $38.33/share.

“We are optimistic about our prospects in the current year as well as longer-term,” stated Bob Akins, Cymer’s chairman and CEO. “Our current cash position and our expectation of generating substantial amounts of cash through the remainder of this year enable us to execute this repurchase plan and to fund our new business development programs as well.”
