Company Also Announces Employee Stock Option Exchange Program

LIVERMORE, Calif. — August 31, 2010 — FormFactor, Inc. (Nasdaq: FORM) today announced that it expects revenue for fiscal third quarter 2010 to be between $46 and $48 million, lower than the previous expectation of the low to mid $50 millions. The lower than expected results are due to the timing of completion of qualifications for the Matrix product family at major customers, the company’s decision to turn away low margin business and longer lead times quoted than customers requested.

“Our new Matrix platform is gaining traction,” said Carl Everett, CEO. “I believe as our Matrix products become fully adopted at all major DRAM manufacturers, it will become the preferred full-wafer-contact probe solution.”

FormFactor also announced today its intent to file a program in which it will offer a voluntary stock option exchange for its employees. The exchange program offer is designed to help the company retain and incentivize employees, with the aim of enhancing value for all shareholders. The program, which was approved by the Board of Directors, will provide FormFactor employees the opportunity to exchange certain stock options with exercise prices that are currently underwater, for replacement options that can be exercised at a price that more closely reflects FormFactor’s current share value. The program excludes named executive officers and Board members.

“Retaining our experienced employees is essential to executing our turnaround plan for FormFactor,” Everett continued. “The stock option exchange provides an opportunity for our employees to eliminate the negative impact of having options that are substantially underwater. It will also encourage them to take part in the turnaround and to create a company that delivers long-term shareholder value.”

A conference call to discuss the financial guidance and the stock option exchange program will be held tomorrow, September 1 at 2:30 p.m. PDT, or 5:30 p.m. EDT. The public is invited to listen to a live web cast of FormFactor’s conference call on the Investors section of the company’s website at www.formfactor.com. An audio replay of the conference call will also be made available approximately two hours after the conclusion of the call. The audio replay will remain available until September 3, 2010 at 9:00 p.m. PDT, and can be accessed by dialing (800) 642-1687 (domestic) or (706) 645-9291 (international) and entering confirmation code 98363594.

This press release is for informational purposes only and is not an offer to buy, or the solicitation of an offer to sell, any stock options.
