Company also announces internal review of inventory valuation practices 

LIVERMORE, Calif. — October 24, 2007 — FormFactor, Inc. (Nasdaq: FORM) today announced revenue for the third quarter of fiscal year 2007, ended September 29, 2007. The Company posted record quarterly revenue of $125.3 million. These results compare to revenue of $114.1 million, a 10% increase from the second quarter of fiscal 2007 and $96.8 million, a 29% increase from the third quarter of fiscal 2006. The company had a cash balance of $537 million as of September 29, 2007.

“FormFactor delivered another record revenue quarter driven by strength in DRAM, NOR and KGD as we continued to lead the market for advanced probe cards. As existing customers migrated to our new product platforms and we penetrated emerging markets such as Wire Bond Logic, design activity also increased,” said Igor Khandros, CEO of FormFactor.

The Company said that it is unable at this time to release further income statement data with respect to the third quarter. The Company is currently reviewing its historic practices with respect to inventory valuation in light of issues identified by the Company in the course of preparation of financial statements for the third quarter. Based on the review to date management believes that adjustments to inventory valuations may be required with respect to periods prior to the third quarter of 2007. These potential adjustments could change inventory, gross margin, operating margin and net income from the amounts previously reported for the affected periods. The Company has not yet determined the magnitude of these adjustments or whether the adjustments will be reflected in the third quarter financial statements or in a restatement of the affected periods. The Company believes, however, that its third quarter operating margin and net income per share, without giving effect to adjustments in respect of prior periods, should be not less than the 20.5%- 21% and $0.38-$0.40 per share, respectively, provided as management guidance in the Q2 earnings call conducted on July 25, 2007.

The Company is working to complete the internal review as promptly as practicable.

The Company has posted its revenue breakdown by region and market segment on the Investors section of its website at www.formfactor.com. FormFactor will conduct a conference call at 1:30 p.m. PDT, or 4:30 p.m. EDT, today. The public is invited to listen to a live web cast of
