Exhibit 99.1 Cerus Corporation Announces Fourth Quarter and Year-End Results CONCORD, Calif.--(BUSINESS WIRE)--Jan. 29, 2004--Cerus Corporation (Nasdaq:CERS) today announced results for the fourth quarter and year ended December 31, 2003. The net loss for the fourth quarter of 2003 was $10.1 million, or $0.46 per share, compared to a net loss of $15.8 million, or $0.99 per share, for the fourth quarter of 2002. For the year ended December 31, 2003, the company reported a net loss of $58.3 million, or $3.01 per share, compared to a net loss of $57.2 million, or $3.61 per share, for 2002. The reduction 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. The increase in the net loss for the year was due primarily to interest expense accrued on a loan from Baxter Capital Corporation, a financial subsidiary of Baxter International Inc. Total revenue from government grants, development agreements and product sales was $3.5 million for the fourth quarter of 2003, compared to $1.6 million for the fourth quarter of 2002. For the year ended December 31, 2003, total revenue was $9.7 million, which included $8.2 million of funding from the U.S. Armed Forces, compared to $8.5 million for 2002, which included a $5.0 million milestone payment from Baxter. At December 31, 2003, the company had cash, cash equivalents and short-term investments of $110.0 million. Loan principal and accrued interest under a credit facility with Baxter Capital Corporation is classified as a current liability on the balance sheet, due to a dispute concerning the timing of repayment. 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(R) technology.
