CERUS CORPORATION ANNOUNCES FIRST QUARTER
FINANCIAL RESULTS
CONCORD, CA, May 1, 2007—Cerus Corporation (NASDAQ: CERS) today announced financial results for the first quarter ended March 31, 2007.
Total revenue for the first quarter of 2007 was $4.7 million, down from $7.0 million for the first quarter of 2006. The decrease in revenue is attributable to no milestone payments or development funding recognized in the current quarter from our agreements with Baxter, BioOne and MedImmune as compared with $3.4 million in the first quarter of 2006. Product revenue was $1.2 million in the first quarter of 2007, up from $0.5 million in the first quarter of 2006. Total operating expenses for the first quarter of 2007 were $12.6 million, up from $10.0 million for the same period in 2006, primarily due to costs associated with our INTERCEPT commercialization efforts in Europe.
Net loss for the first quarter of 2007 was $6.8 million, or $0.21 per share, compared to a net loss of $0.9 million, or $0.04 per share, for the first quarter of 2006.
At March 31, 2007, the Company had cash, cash equivalents and short-term investments of $79.6 million.
“I am pleased to announce that product revenue for the first quarter of 2007 for our INTERCEPT Blood System was over one million dollars,” said Claes Glassell, president and CEO of Cerus Corporation. “We believe that the interest in pathogen inactivation is increasing. By marketing the INTERCEPT system as a single system that treats both platelet and plasma donated blood components intended for transfusion, we believe that we can offer customers a solution that is operationally, economically and clinically superior to conventional screening and blood testing practices.”
