Item 2.02 Results of Operations and Financial Condition.

     (a)

     The information in this Item 2.02 and the exhibit attached hereto are being furnished pursuant to Item 2.02 of Form 8-K and shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, nor shall they be deemed incorporated by reference in any filing with the Securities and Exchange Commission under the Securities Act of 1934 or the Securities Act of 1933, except as shall be expressly set forth by specific reference to such filing.

     On November 1, 2007, Cepheid issued a press release announcing its financial results for the quarter ended September 30, 2007 and certain other information. The press release is attached to this report as Exhibit 99.01.

     In the press release and during a conference call and webcast regarding Cepheid’s quarterly results, Cepheid supplemented its reported GAAP financials with non-GAAP measures. Cepheid uses the non-GAAP information internally to evaluate its continuing operational performance and its cash requirements, and believes these non-GAAP measures are useful to investors as they provide a basis for evaluating the company’s cash requirements and additional insight into the underlying operating results and the company’s ongoing performance in the ordinary course of its operations. However, non-GAAP measures are not stated in accordance with, should not be considered in isolation from, and are not a substitute for GAAP measures, and Cepheid’s non-GAAP measures may be different from similarly titled non-GAAP measures reported by other companies. A reconciliation of GAAP to non-GAAP results is provided in the tables immediately following the GAAP Consolidated Financial Statements included in the press release.

Item 5.02 Departure of Directors or Principal Officers; Election of Directors; Appointment of Principal Officers; Compensatory Arrangements of Certain Officers.

     (b)

     On November 1, 2007, Cepheid announced that John R. Sluis, its Senior Vice President of Finance and Chief Financial Officer, intends to retire. Cepheid and Mr. Sluis intend that Mr. Sluis will continue in his current position during a transitional period through December 31, 2007. Cepheid is currently working with an outside executive search firm to identify a new chief financial officer.
