Exhibit 99.1 Cepheid Reports First Quarter 2004 Results Total Revenues Increase by 92% Driven by 112% Increase in Product Sales Gross Margin Dollars on Product Sales Increase by 174% SUNNYVALE, Calif., May 5 /PRNewswire-FirstCall/ -- Cepheid (Nasdaq: CPHD) today announced financial results for the quarter ended March 31, 2004. Product sales for the quarter ended March 31, 2004 increased 112% to approximately $6.6 million from approximately $3.1 million for the corresponding prior year period. The increase in product sales for the quarter ended March 31, 2004 as compared to the corresponding prior year period was due to a 423% increase in reagent and disposable sales and a 74% increase in instrument sales. Total revenues for the quarter ended March 31, 2004 increased 92% to approximately $7.3 million compared to approximately $3.8 million for the corresponding prior year period. The increase in total revenue for the quarter ended March 31, 2004 as compared to the corresponding prior year period was due primarily to the increase in product sales. Contract revenue of $0.6 million for the quarter ended March 31, 2004 was primarily derived from the amortization of up-front license fees in connection with the Company's collaboration with bioMerieux. Gross Margin Dollars on product sales (total product sales less cost of product sales) for the quarter ended March 31, 2004 increased by 174% as compared to the corresponding prior year period. The gross margin percentage on product sales for the quarter ended March 31, 2004 increased to 55% compared to 42% for the corresponding prior year period. The increase in gross margin percentage on product sales for the quarter ended March 31, 2004 as compared to the corresponding prior year period is due primarily to a change in product mix to higher gross margin products. Gross margin on product sales for future quarters will be substantially impacted by higher royalties related to an anticipated license arrangement discussed below, but are expected to remain within the range of management's previous guidance. Operating expenses for the period ended March 31, 2004, included an accrued liability in the amount of $1.3 million for anticipated royalties on past product sales. In that regard, the company approached the owner of certain patents to negotiate a worldwide license to certain technology for which general terms have been agreed upon and the negotiations are ongoing to finalize the definitive license agreement. The Company expects to record resulting future royalty obligations as the related product sales are recognized. Inclusive of the noted accrual, net loss for the quarter ended March 31, 2004 was approximately $4.1 million, or $0.11 per share, compared to a net loss of approximately $4.7 million, or $0.15 per share for the corresponding prior year period. "The Company had a strong quarterly performance on both an operating and strategic level," stated John Bishop, Cepheid's Chief Executive Officer. "We completed a public offering of 5,500,000 shares of common stock which increased our cash balance by $57.7 million, net of expenses. This places us in a strong position to carry out key strategic initiatives while also potentially achieving positive cash flow from operations without returning to the capital markets. Significant sales of GeneXpert(R) modules and anthrax test cartridges were realized during the quarter for Biohazard Detection System (BDS) units scheduled to be deployed at selected United States Postal Service (USPS) sites. Site deployment was initiated in March with a number of units deployed at multiple sites. However, as discussed in Cepheid's press release on April 29, additional deployment is temporarily on hold pending resolution of an observed increase in the rate of non-determinate results, which occurred at a small number of sites on a limited number of mail sorting lines on which BDS units were installed. Our collaborator Infectio Diagnostic Inc. (IDI) received 510(k) clearance from the US Food and Drug Administration (FDA) to market its new IDI-MRSA(TM) test for detecting methicillin-resistant Staphylococcus aureus (MRSA). According to IDI it is the first MRSA test cleared by the FDA for use directly on clinical specimens. This represents the second in our developing pipeline of Clinical Genetic Assessment products. Running on our SmartCycler(R) system, the speed and simplicity of IDI-MRSA test is expected to make it ideal for routine laboratory use, with rapid results helping to ensure effective management of true MRSA carriers in the hospital environment. MRSA is one of the main causes of hospital-acquired infections affecting thousands of hospitalized patients every year. Sales of our other existing products in the Life Sciences and Clinical Genetic Assessment markets also demonstrated positive growth during the quarter in both our domestic and international markets." 2004 Outlook Commenting on Cepheid's outlook for the remainder of 2004, Mr. Bishop stated: "We expect to move forward with a number of key events during the second quarter. Three significant market launches are scheduled to take place at the American Society of Microbiology meeting during the week of May 24, 2004. The IDI-MRSA test for use on the SmartCycler is planned for market launch along with the market launch of the SmartCycler family of higher throughput systems specifically set up for simultaneous analysis of 16, 32, 48 and 64 tests. The GeneXpert System for use in the BioThreat market along with the anthrax test cartridge and a manual sample collection kit is also scheduled for launch. In addition, as previously announced our expected release of the GeneXpert System into the Life Sciences market is planned for later in the year with an ASR product for use in Leukemia research. We also expect to release a number of ASR products for use in infectious disease on the SmartCycler System before the end of the year that have not previously been discussed. These products are expected to include specific analytes for Herpes simplex 1&2, Cytomegalovirus (CMV), Bordetella pertussis, Enterovirus (EV), Epstein-Barr virus (EBV) and Norwalk virus. We further expect to significantly expand our ASR product lines for use in infectious disease research in 2005 along with additional tests for cancer research. As discussed in our press release dated April 29, 2004, the further deployment of the BDS units at USPS sites around the country has been temporarily suspended in order to investigate an anomaly in the rate of non-determinate tests experienced on a small number of mail sorting lines on which BDS units have been installed. A non-determinate test does not indicate a threat is suspected; it simply means that the test did not provide an answer. A team comprised of representatives from the USPS, Northrop Grumman and Cepheid scientists is investigating the issue. Adjustments made to some of the mail sorting lines involved appear to have eliminated the previously observed anomaly; however, additional work is continuing to better characterize the phenomenon. At this time, we are confident that the GeneXpert module and anthrax test cartridges are functioning as expected. We are currently continuing to ship test cartridges for use on deployed units and to build modules for BDS units yet to be deployed. We reaffirm that we expect our 2004 product sales to be in the range of $42.0 million to $46.0 million, based on phase one sales for the USPS program and sales expected from other existing products. Due to the March implementation of the BDS deployment and due to seasonal factors, we continue to expect realization of our product sales to be more heavily weighted toward the second half of the year. This guidance does not include any potential product sales that may result if the USPS elects to initiate deployment of the phase two option during 2004. Our gross profit margin on product sales for 2004 is expected to improve over that achieved in 2003; however, it may not be at the level achieved for the first quarter of 2004. We also reaffirm that we expect our 2004 net loss to be in the range of $10.5 million to $12.5 million or $0.27 to $0.32 per share based on actual weighted average shares outstanding of 38.7 million as of March 31, 2004." As of March 31, 2004, the Company had $72.5 million in unrestricted cash. This is expected to carry the Company to a positive operating cash flow position consistent with our strategic plan.
