CERUS CORPORATION ANNOUNCES SECOND QUARTER FINANCIAL RESULTS

CONCORD, CA, July 30, 2009 - Cerus Corporation (NASDAQ: CERS) today announced financial results for the second quarter ended June 30, 2009.

Revenue for the second quarter of 2009 was $4.2 million, up from $4.0 million in revenue recognized during the second quarter of 2008. Total revenue for the first six months of 2009 was $7.7 million, down from $9.0 million recognized during the first six months of 2008, primarily due to $1.5 million in 2007 product sales initially deferred and recognized as revenue during the first six months of 2008. Product revenue for the INTERCEPT Blood System was $3.9 million during the second quarter of 2009, representing an increase of $0.8 million, or 25%, from the first quarter of 2009. Second quarter 2009 product revenue was in line with the $4.0 million recorded during the second quarter of 2008, when $0.3 million of previously deferred product revenue was recognized. Product revenue for the first six months of 2009 was $7.0 million, down from $8.9 million during the first six months of 2008, when the $1.5 million of previously deferred product revenue was recognized. Government grant revenue recognized during the second quarter of 2009 was $0.3 million; no government grant revenue was recognized during the second quarter of 2008. Government grant revenue for the first six months of 2009 was $0.7 million, up from $0.1 million in government grant revenue recognized during the first six months of 2008.

Total operating expenses for the second quarter of 2009 were $7.2 million, down from $10.1 million for the same period in 2008. The decrease in operating expenses was due to a reduction in research and development expenses and selling, general and administrative expenses, partially offset by second quarter 2009 non-recurring restructuring costs of $0.1 million associated with the Company’s restructuring plans, previously announced in March 2009. Operating expenses for the first six months in 2009 were $16.0 million, down from $20.0 million during the same period in 2008. The reduction in operating expenses was directly attributable to the savings realized from the Company’s restructuring plan, which provided for the Company to focus resources on commercializing the INTERCEPT platelet and plasma systems in Europe, reduce operating expenses, and tightly manage working capital.

Net loss for the second quarter of 2009 was $6.2 million, or $0.19 per share, compared to a net loss of $8.9 million, or $0.28 per share, for the second quarter of 2008. Net loss for the first six months of 2009 was $13.6 million, or $0.42 per share, compared to a net loss of $14.9 million, or $0.46 per share, for the same period in 2008.

At June 30, 2009, the Company had cash, cash equivalents and short-term investments of $12.9 million, down from $22.6 million at December 31, 2008 and $15.4 million at March 31, 2009, reflecting net cash consumption of $2.5 million for the second quarter. Overall, cash consumption slowed significantly during the second quarter of 2009, as the Company began implementing and realizing the impact from its previously announced restructuring plan. As a consequence, the Company continues to expect that existing cash resources will be adequate to fund the Company’s operations into 2010.

“We are pleased with the outcome of our initiatives to reduce cash expenditures and focus on commercializing the INTERCEPT Blood System in Europe and the Middle East. This quarter, we achieved significant commercial progress in key markets while also reducing spending, which extends our cash runway and shortens the bridge towards profitability,” said Claes Glassell, President and Chief Executive Officer of Cerus Corporation.

RECENT HIGHLIGHTS:

• Achieved 25% sequential growth in product revenue during the second quarter of 2009;

• Reduced cash burn by more than 65% from the first quarter of 2009;

• Extended supply agreement with French national blood service (EFS) and added two additional regional centers; now supplying INTERCEPT to six of seventeen regions of EFS;

• Increased Belgian platelet market share to approximately 40%; Belgium Royal Decree now mandates universal use of pathogen inactivation for platelets by August 2010;

• Expanded the distribution relationship with Grifols, adding Italy to the INTERCEPT territory that already included Spain and Portugal;

• Completed enrollment in Phase I clinical trial for the red blood cell system; and

• Submitted proposed protocol to FDA for platelet system Phase III clinical trial.
