On October 28, 2009, FormFactor, Inc. issued a press release announcing its financial results for the third quarter ended September 26, 2009. A copy of the press release is furnished as Exhibit 99.01 to this report and is incorporated herein by reference.

In addition to disclosing financial results calculated in accordance with United States generally accepted accounting principles ("GAAP"), the press release contains non-GAAP financial measures. Specifically, the press release includes non-GAAP net loss and non-GAAP net loss per share. The company excluded the following items from one or more of its published non-GAAP measures: deferred tax valuation allowance, stock-based compensation expenses and restructuring charges. By publishing the non-GAAP measures, the company's management intends to provide investors with additional information to further analyze the company's performance, core results and underlying trends. FormFactor's management evaluates results and makes operating decisions using both GAAP and non-GAAP measures included in the press release. Non-GAAP results are not prepared in accordance with GAAP, and non-GAAP information should be considered a supplement to, and not a substitute for, financial statements prepared in accordance with GAAP. Investors and potential investors are encouraged to review the reconciliation of non-GAAP financial measures to their most directly comparable GAAP measures included in the press release and on the Investors section of the company's website.
