DYNAVAX ANNOUNCES THIRD QUARTER 2004 FINANCIAL RESULTS

BERKELEY, Calif — November 8, 2004 — Dynavax Technologies Corporation (Nasdaq: DVAX) today reported financial results for the third quarter 2004. Dynavax reported a net loss of $4.0 million for the quarter ended September 30, 2004, or $0.16 share, compared to a net loss of $4.1 million, or $2.30 per share for the same period in 2003. For the nine months ended September 30, 2004, net loss was $10.8 million or $0.54 share compared to $12.8 million or $7.20 per share for the comparable period in 2003. The net loss per share for the three and nine months ended September 30, 2004 reflects the increase in common shares outstanding as a result of the Company’s initial public offering in February 2004.

As of September 30, 2004, cash, cash equivalents and marketable securities totaled $71.5 million compared to $74.0 million at June 30, 2004 and $29.1 million at December 31, 2003.

Revenue for the third quarter ended September 30, 2004 was $ 3.7 million compared to $0.02 million for the same period in 2003. For the nine months ended September 30, 2004, total revenues were $12.4 million, compared to $0.1 million for the comparable period of 2003. The increase in revenue is due to the Company’s collaborative agreement with UCB Pharma in ragweed and grass allergies, which was initiated in 2004, and biodefense grants awarded by the National Institute of Allergy and Infectious Diseases.

Total operating expenses were $7.9 million for the third quarter 2004 compared to $4.3 million for the same period in 2003. Operating expenses for the nine months ended September 30, 2004 totaled $23.7 million as compared to $13.3 million in the comparable period of 2003. The increase in operating expenses is primarily due to increased clinical trial activities in the Company’s ragweed allergy, hepatitis B vaccine, and asthma programs, as well as preclinical work associated with government grants for biodefense programs. This increase also reflects higher expenses associated primarily with the expanding of our management team and additional obligations associated with being a public company.

“In the third quarter, we made excellent progress in advancing our clinical programs, in bringing additional depth and breadth to our senior management team, and in maintaining a high level of fiscal responsibility,” said Dino Dina, MD, president and chief executive officer. “We anticipate initiating Phase 3 clinical trials for our two lead clinical programs in ragweed allergy and in Hepatitis B in the first half of 2005, pending results of interim analyses in these programs. Our corporate partners continue to be supportive of our efforts. We established a promising collaboration with the prestigious Riken Institute in Japan with the goal of developing an ISS-based cedar allergy therapy. We believe that this collaboration, combined with our clinical progress, underscores the broad therapeutic potential of our ISS technology. Our balance sheet remains healthy and our financial performance is in line with our expectations. We believe that this year will be one of progress and achievement for our company.”
