Dynavax Announces First Quarter 2008 Financial Results

Revenues Increase for Quarter, Per Share Net Loss Narrows

BERKELEY, Calif., Apr 29, 2008 (BUSINESS WIRE) -- Dynavax Technologies Corporation (Nasdaq: DVAX) today reported financial results for the first quarter ended March 31, 2008.

As of March 31, 2008, Dynavax reported cash, cash equivalents, marketable securities and investments held by Symphony Dynamo, Inc. (SDI) totaling $73.2 million. This compares to $88.2 million at December 31, 2007.

For the first quarter 2008, total revenues were $6.3 million, compared to $2.0 million reported for the first quarter in 2007. The increase in revenues for the first quarter reflects research and development funding from Merck & Co. Inc. for HEPLISAV(TM), our hepatitis B vaccine product candidate. The reported revenues do not include collaboration funding from Symphony Dynamo Inc. (SDI) for cancer and HCV clinical activities. On a pro forma basis, including the collaboration funding from SDI, revenues were $7.8 million for the first quarter 2008, compared to $5.5 million for the first quarter 2007.

The company indicated that HEPLISAV had been placed on clinical hold by the U.S. Food & Drug Administration (FDA) prior to the close of the quarter, and is working with its commercialization partner Merck to respond in a timely manner.

For the first quarter 2008, total operating expenses were $19.9 million compared to $18.1 million for the first quarter 2007. The increase in operating expenses resulted primarily from overall organizational growth in the U.S. to support the Company's product pipeline and the expansion of our manufacturing capabilities in Europe related to potential commercialization of HEPLISAV. The operating expenses included non-cash charges for stock-based compensation and amortization of intangible assets. Excluding the non-cash charges, pro forma operating expenses were $19.0 million for the first quarter 2008 compared to $17.0 million for the first quarter 2007.

The tables included as part of this press release provide a reconciliation of GAAP revenues and operating expenses to pro forma revenues and operating expenses.

The net loss of $12.4 million, or $0.31 per share, reported for the first quarter 2008 was less than the net loss of $13.1 million, or $0.33 per share, for the same period in 2007. For the first quarter, the improvement in net loss reflected the increase in revenues, in particular, revenue associated with the Merck collaboration.

(1) These pro forma amounts are intended to illustrate the Company's revenues to be inclusive of collaboration funding provided for the SDI programs. The collaboration funding is reflected in the amount attributed to the noncontrolling interest in SDI in the Company's consolidated statement of operations, but would have been reported as revenue if SDI's results of operations were not consolidated with those of the company. Management of the company believes the pro forma results are a more useful measure of the Company's revenues because it provides investors the ability to evaluate the Company's operations in the manner that management uses to assess the continued progress of programs funded under the SDI arrangement. These pro forma results are not in accordance with, or an alternative for, generally accepted accounting principles and may be different from pro forma measures used by other companies.
