Exhibit 99.1 VaxGen Releases First-Quarter Financial Results; Revenues Rise and Losses Decline Brisbane, Calif. - May 13, 2003 - VaxGen, Inc. (Nasdaq: VXGN) today announced financial results for the first quarter ended March 31, 2003. The company reported an increase in revenue due primarily to its anthrax vaccine development contract and a decrease in losses stemming from lowered clinical trial costs. Revenue for the most recent quarter totaled $1,200,000, compared to $18,000 in the quarter ended March 31, 2002. The company reported a net loss applicable to common stockholders of $6.8 million, or 43 cents per share, for the most recent quarter, compared to net loss applicable to common stockholders of $7.7 million, or 54 cents per share, in the quarter ended March 31, 2002. These financial results are presented according to GAAP. VaxGen provides financial results in GAAP and pro forma formats in order to more clearly present the company's financial performance. GAAP presentations include certain non-cash charges, whereas our pro forma presentations exclude them. On a pro forma basis, which excludes charges related to VaxGen's convertible preferred stock, the company reported a net loss of $6.6 million, or 42 cents per share, for the quarter ended March 31, 2003, compared with a net loss of $7.0 million, or 49 cents per share, in the comparable quarter of 2002. The company has implemented a series of cost-savings measures which, combined with its existing financial resources, including government contracts and grants, will enable the company to meet its forecasted expenditures through approximately November 2003, as previously reported in the company's Form 10-K filed with the Securities and Exchange Commission on March 31, 2003. VaxGen ended the first quarter with $10.1 million in cash and investment securities, compared with $18.0 million at the end of the previous quarter. For the remainder of the year, the company expects cash receipts of approximately $16.5 million from existing contracts, grants and other sources. The company intends to raise additional funding as necessary to support its operations beyond November. "VaxGen is taking aggressive measures to control its costs while focusing on near-term business opportunities to strengthen its balance sheet," said Lance K. Gordon, Ph.D., VaxGen's CEO. "Given the progress we've made on our current initiatives and the inherent opportunities in them, we believe we will be able to raise additional funds through a combination of revenue-generating sources and equity capital." Since the beginning of the first quarter, VaxGen has: o Met the early milestones associated with its anthrax vaccine development contract with the U.S. National Institutes of Health. This included completing preclinical product development, cGMP production of vaccine for animal efficacy and 3 clinical studies, and preparing for a Phase I clinical trial scheduled to begin in the second quarter of 2003. This trial will compare the safety and immunogenicity of VaxGen's candidate with the currently licensed anthrax vaccine. The contract, which was awarded last fall, also requires VaxGen to provide a plan for how it could manufacture an emergency stockpile of at least 25 million doses of the vaccine; o Completed construction of its cGMP manufacturing facility in South San Francisco. The facility will be used to manufacture anthrax vaccine if VaxGen is awarded U.S. government contracts for this purpose, and AIDSVAX if the company receives government funding for additional Phase III trials; o Began construction of a large-scale biologics manufacturing facility in South Korea, through its joint venture, Celltrion; and o Announced preliminary results of its Phase III clinical trial of AIDSVAX B/B. VaxGen is in discussion with the NIH and Centers for Disease Control and Prevention, which supported a portion of the recently completed trial, regarding the possibility of those organizations and others providing funding for ongoing analysis and new clinical trials. "VaxGen would welcome the opportunity to continue developing AIDSVAX, but only if government agencies and philanthropic organizations provide the necessary funding," said Lance K. Gordon, Ph.D., VaxGen's CEO. "Regardless of the next steps for AIDSVAX, we intend to continue focusing on our current programs in biodefense vaccines while exploring new opportunities. The U.S. government recently announced its intent to award a new contract for the advanced development of a recombinant anthrax vaccine later this year. The U.S. government earlier announced its intent to contract for the manufacture of an emergency stockpile of at least 25 million doses. Having met the milestones so far associated with our existing anthrax vaccine contract, we think VaxGen is a front-runner to win both of these forthcoming contracts." VaxGen expects to conclude an agreement by the end of June with Chemo-Sero-Therapeutic Research Institute (Kaketsuken) of Kumamoto, Japan, which would finalize the business terms associated with a previously announced partnership to develop a safer smallpox vaccine. Kaketsuken's smallpox vaccine, LC16m8, was developed to have an improved safety profile while retaining the potency to meet Japanese and World Health Organization requirements for licensure. The vaccine was licensed in Japan in 1980 and was safely administered to 50,000 children there. VaxGen intends to conduct clinical trials for the purpose of licensing the vaccine in the United States. "Well over 50% of Americans indicate that they want to be immunized against smallpox, but as we have seen from recent events, existing smallpox vaccines are associated with serious side effects that the public appears unwilling to accept," Gordon said. "Other smallpox vaccines in development have not been specifically developed to avoid these safety concerns and/or have 4 yet to show that they are efficacious. We believe that leaves LC16m8 as the logical alternative with which to immunize the population against the threat of smallpox."
