Cascade Microtech Completes Sale of Test Socket Division and

Establishes Stock Repurchase Program

BEAVERTON, OR, September 26, 2011 — Cascade Microtech, Inc. (NASDAQ: CSCD) today announced that it has completed the sale of its test socket manufacturing business for a purchase price of $550,000 to R&D Interconnect Solutions, a wholly owned subsidiary of R&D Circuits, based in Brooklyn Park, Minnesota.

The Company also announced that its board of directors has authorized a stock repurchase program under which up to $2,000,000 of the Company’s common stock may be repurchased. Under the terms of the stock repurchase program, shares may be purchased from time-to-time in the open market or in privately negotiated transactions. The timing and actual number of shares purchased will depend on a variety of factors, including market conditions, corporate and regulatory requirements, and alternative business and investment opportunities. Repurchases under the program will be funded from available cash. The program does not require the Company to acquire any particular amount of common stock, and the program may be commenced, suspended or terminated at any time or from time-to-time at the Company’s discretion without prior notice.

“We believe our stock is currently undervalued,” said Michael Burger, President and CEO. “As a result, we see this repurchase program as a prudent use of capital. We believe that both this program and the sale of our test socket business underscore our commitment to building long-term value for our shareholders.”

The Company is scheduled to announce its financial results for its third quarter ending September 30, 2011 on November 1, 2011. The Company will not purchase any stock under the repurchase program before that time.
