[LOGO VaxGen] VaxGen Releases Second-Quarter Financial Results: Revenue Increases as Operating Loss Declines Brisbane, Calif. - August 5, 2003 - VaxGen, Inc. (Nasdaq: VXGN) today announced financial results for the second quarter ended June 30, 2003. Revenue for the most recent quarter totaled $2.8 million, compared to $220,000 in the quarter ended June 30, 2002. The increase was due primarily to revenue from VaxGen's contract with the National Institute of Allergy and Infectious Diseases (NIAID) to fund development of an anthrax vaccine. The company reported a consolidated net loss applicable to common stockholders of $7.5 million, or 43 cents per share, for the most recent quarter, compared to a net loss applicable to common stockholders of $7.4 million, or 52 cents per share, in the quarter ended June 30, 2002. The loss in the second quarter of 2003 included non-cash charges of $1.0 million attributable to VaxGen's convertible preferred stock. VaxGen's second-quarter results now reflect assets, liabilities and operating results associated with the company's majority-owned biopharmaceutical manufacturing subsidiary in South San Francisco. This change in accounting method, which is in accordance with GAAP, is the result of VaxGen's increased level of ownership of the subsidiary in the quarter ended June 30, 2003 resulting from the company's ongoing investment in the subsidiary. On a pro forma basis, which excludes charges related to VaxGen's convertible preferred stock, the company reported a net loss of $6.5 million, or 37 cents per share, for the quarter 1 ended June 30, 2003, compared to a net loss of $6.7 million, or 46 cents per share, in the comparable quarter of 2002. VaxGen believes that the non-GAAP results in this press release provide useful information to investors because they exclude the effects of non-cash charges that the company believes are not indicative of its on-going operations. The non-GAAP information is provided as a complement to results provided in accordance with GAAP and should not be considered better than, or a substitute for, GAAP measures. VaxGen had $14.6 million in cash and investment securities as of June 30, 2003, compared with $11.9 million at the end of the previous quarter ended March 31, 2003. "We continue to believe that our existing cash, plus anticipated income from existing government contracts and grants, will allow us to fund our operations through approximately the first quarter of 2004," said Carter A. Lee, VaxGen's senior vice president of Finance and Administration. "We expect to fund our operations beyond that date through existing and new government contracts and grants and/or equity financing." Net cash expenditures for the second quarter totaled $9 million. This figure reflects the company's net loss, as well as $2.2 million in final payments to clinical sites associated with the company's Phase III HIV vaccine trial in North America and Europe, which concluded earlier this year. Cash expenditures also reflected $4.7 million in payments, principally for capital equipment, associated with VaxGen's majority-owned biopharmaceutical manufacturing subsidiary in South San Francisco. VaxGen is using its manufacturing facility to support its current anthrax vaccine contract and is proposing its use to meet the requirements of future anthrax vaccine development and supply contracts. 2 "With the investments we've made in our manufacturing capacity and our track record of performance under our existing anthrax vaccine contract, we believe VaxGen is well positioned to secure a second NIAID contract for advanced development of an anthrax vaccine candidate," said Lance K. Gordon, Ph.D., VaxGen's CEO. The U.S. government is expected to award at least two additional contracts for anthrax vaccine. The NIAID is expected to award one or more contracts for the advanced development of a recombinant anthrax vaccine before the end of the third quarter of 2003. This contract or contracts are intended to fund commercial scale-up and demonstration of manufacturing, as well as Phase II trials and animal efficacy studies. Separately, Project BioShield calls for the creation and maintenance of a 60-million-dose stockpile of anthrax vaccine. The U.S. House of Representatives recently passed the measure by a vote of 421 to 2. The U.S. Senate is expected to act shortly. According to a recent Congressional Budget Office (CBO) estimate for the House-passed bill, the U.S. government anticipates spending $1.4 billion between 2004 and 2013 on the procurement, maintenance and replacement of an anthrax vaccine stockpile under Project BioShield, if Project BioShield is signed into law. The CBO report states that the government expects to purchase an anthrax vaccine made from recombinant anthrax Protective Antigen (rPA). VaxGen's candidate anthrax vaccine was specifically developed under its existing NIAID contract to meet this requirement. "If Project BioShield is signed into law," Gordon said, "VaxGen expects to aggressively pursue opportunities under this program." 3 Second-Quarter Highlights o VaxGen announced that the U.S. Food and Drug Administration (FDA) had cleared an Investigation New Drug application (IND) for the company's anthrax vaccine candidate, rPA102. The IND allowed VaxGen to begin a Phase I clinical trial, which is now fully enrolled and underway at four leading medical centers in the United States. o The field work on VaxGen's second Phase III HIV vaccine trial was completed. The company expects to announce results from the trial, which took place in Thailand, in the fourth quarter of 2003. o VaxGen announced that it had been awarded a phase 2 Small Business Innovation Research (SBIR) grant from the NIAID to identify novel antigens for potential use in future HIV vaccine candidates. The SBIR grant provides up to $2 million for the program and is in addition to the $210,000 that VaxGen received late last year through phase 1 of the grant. o VaxGen proceeded with preparations to introduce the LC16m8 smallpox vaccine into the United States. This vaccine was developed in Japan and licensed there in 1980. Trials in 50,000 children showed the vaccine had a better safety profile than other vaccines licensed for prevention of smallpox. VaxGen has already received an initial supply of the vaccine from its Japanese manufacturer, Kaketsuken, and anticipates receiving 1 million doses of bulk vaccine for the purpose of initiating clinical trials early next year. 4 o VaxGen raised net proceeds of $11.7 million through two separate equity financings. The proceeds are being used to fund capital investments in VaxGen's majority-owned manufacturing subsidiary and for general corporate purposes. o VaxGen celebrated the opening of its biopharmaceutical manufacturing facility in South San Francisco. Financed in part by VaxGen's joint venture partner, Celltrion, Inc., the facility includes cGMP suites occupying 17,000 square feet for the production of vaccines, monoclonal antibodies and therapeutic proteins. VaxGen also intends to use the facility for training purposes leading to the transfer of technology to a larger biopharmaceutical manufacturing facility in South Korea that will be operated by Celltrion.
