DYNAVAX REPORTS FIRST QUARTER 2011 FINANCIAL RESULTS

BERKELEY, CA – May 5, 2011 – Dynavax Technologies Corporation (NASDAQ: DVAX) today reported financial results for the first quarter ended March 31, 2011, including $53.2 million in cash, cash equivalents and marketable securities at March 31, 2011. A $6 million milestone payment from GlaxoSmithKline earned after the close of the quarter from the initiation of a Phase 1 trial in the partnered lupus program was not included in the reported cash balance of $53.2 million. At December 31, 2010, Dynavax reported $72.2 million in total cash.

Total operating expenses for the quarter were in line with earlier expense guidance that full year 2011 expenses will be consistent with 2010. Net cash usage for the first quarter 2011 was higher than the average quarterly net cash usage during 2010, due to significant payments for the large-scale Phase 3 study of HEPLISAV™ which completes this month. The Company anticipates a reduction in ongoing quarterly spend through the remainder of 2011 such that its average quarterly net cash usage should approximate $13 million for 2011.
