Exhibit 99.1 Cerus Corporation Announces Third Quarter Results CONCORD, Calif.--(BUSINESS WIRE)--Oct. 30, 2003--Cerus Corporation (Nasdaq:CERS) today announced results for the third quarter ended September 30, 2003. The net loss for the third quarter of 2003 was $14.2 million, or $0.64 per share, compared to a net loss of $16.6 million, or $1.05 per share, for the third quarter of 2002. The decrease in the net loss for the quarter was due primarily to increased funding received under cooperative agreements with the U.S. Armed Forces and reduced operating expenses. Total revenue from government grants, development agreements and product sales was $2.9 million for the third quarter of 2003, compared to $0.7 million for the third quarter of 2002. For the nine-month period, total revenue was $6.1 million for 2003, which included $5.3 million of funding from the U.S. Armed Forces, compared to $6.9 million for 2002, which included a $5.0 million milestone payment from Baxter. At September 30, 2003, the company had cash, cash equivalents and short-term investments of $123.1 million. Loan principal and accrued interest totaling $54.4 million under a credit facility with Baxter Capital Corporation, a financial subsidiary of Baxter International Inc., has been reclassified to a current liability on the balance sheet, due to a dispute concerning the timing of repayment. Details of the loan dispute were announced by Cerus on October 15, 2003 in a press release and current report on Form 8-K. In addition to financial results, Cerus also announced that the company has been informed by Baxter that it has been notified by the regulatory body in France that the review of the INTERCEPT platelet marketing application is complete and the agency has granted authorization for the preparation, distribution and therapeutic use of the product. Commercial availability of the product is subject to publication of a decree in the Official Journal to register INTERCEPT Platelets and define their specifications, according to standard procedure. Cerus and subsidiaries of Baxter International Inc. are collaborating on development of the INTERCEPT Blood System to enhance the safety of blood transfusions. The INTERCEPT Blood System for platelets is being commercialized in Europe. The product is not yet approved in the United States. In addition to the INTERCEPT Blood System, Cerus also is developing therapeutic and vaccine applications of its Helinx technology. The company's Epstein-Barr virus vaccine is designed to protect organ transplant patients against this virus, which can potentially cause malignant lymphoma. The company also is developing an allogeneic cellular immune therapeutic (ACIT) designed to improve the outcome of stem cell transplantation.
