CEPHEID REPORTS 2013 FIRST QUARTER RESULTS

Clinical Reagent Revenue Growth of 23% Driven by Continued Momentum of Xpert^® Test Portfolio

SUNNYVALE, California, April 18, 2013 – Cepheid (Nasdaq: CPHD) today reported revenues for the first quarter of 2013 of $91.9 million, representing growth of 19% from $77.3 million for the first quarter of 2012. Net income was $0.3 million, or $0.00 per share, which compares to net loss of $5.5 million, or $(0.08) per share, in the first quarter of 2012.

Excluding employee stock-based compensation and amortization of purchased intangible assets, non-GAAP net income for the first quarter of 2013 was $7.8 million, or $0.11 per share. This compares to a non-GAAP net loss of $1.2 million, or $(0.02) per share, in the first quarter of 2012.

“This was a solid start to 2013 for Cepheid with strong performance in our commercial clinical reagents driven both by broader test menu utilization by our installed base of more than 3,000 commercial GeneXpert^® system customers globally and by new customer adoption,” said John Bishop, Cepheid’s Chairman and Chief Executive Officer. “Our leading portfolio of molecular HAI tests continues to drive Cepheid’s growth, but we were particularly pleased with the very strong level of interest in Xpert CT/NG in the first quarter, with about 10% of our North American installed base already using or validating the assay.”

Operational Overview

Business Outlook

For the fiscal year ending December 31, 2013, the Company continues to expect:

Expected non-GAAP net income excludes approximately $29 million related to stock compensation expense and approximately $4 million related to the amortization of acquired intangibles. The fully diluted share count for the year is expected to be approximately 72 million, except in the event of a GAAP loss where the share count would be approximately 67 million shares.

The following table reconciles net income (loss) per share to the non-GAAP net income per share range:

Use of Non-GAAP Measures

The Company has supplemented its reported GAAP financial information with non-GAAP measures that do not include employee stock-based compensation expense, amortization of purchased intangible assets and a tax benefit related to an intercompany intellectual property transaction. The presentation of this additional information is not meant to be considered in isolation or as a substitute for results prepared in accordance with U.S. GAAP. The Company’s management uses the non-GAAP information internally to evaluate its ongoing business, continuing operational performance and 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.

These non-GAAP measures may be different from non-GAAP measures used by other companies. In addition, these non-GAAP measures are not based on any comprehensive set of accounting rules or principles. The Company believes that non-GAAP measures have limitations in that they do not reflect all of the amounts associated with its results of operations as determined in accordance with U.S. GAAP and that these measures should only be used to evaluate the Company’s results of operations in conjunction with the corresponding GAAP measures.

As described above, the Company excludes the following items from one or more of its non-GAAP measures when applicable:

Employee Stock-based Compensation Expense. These expenses consist primarily of expenses for employee stock options and employee restricted stock under ASC 718 (formerly SFAS 123(R)). The Company excludes employee stock-based compensation expenses from its non-GAAP measures primarily because they are non-cash expenses that the Company does not believe are reflective of ongoing operating results in the period incurred. Further, as the Company applies ASC 718, it believes that it is useful to investors to understand the impact of the application of ASC 718 on its results of operations.

Amortization of Purchased Intangible Assets. The Company incurs amortization of purchased intangible assets in connection with acquisitions. The Company excludes these items because these expenses are not reflective of ongoing operating results in the period incurred. These amounts arise from the Company’s prior acquisitions and have no direct correlation to the operation of the Company’s business.

Tax Benefit Related to Intercompany Intellectual Property (IP) Transaction. The Company excluded a tax benefit related to an intercompany IP transaction from its results for non-GAAP net loss for the first quarter ended March 31, 2012. The Company excluded this item as it believes it is non-recurring in nature, and does not have a direct impact on the operation of the Company’s core business.
