Financial Results for the Three Months Ended June 30, 2021

Novavax reported a net loss of $352 million, or $4.75 per share, for the second quarter of 2021, compared to a net loss of $18 million, or $0.30 per share, for the second quarter of 2020.

Novavax revenue in the second quarter of 2021 was $298 million, compared to $36 million in the same period in 2020. This increase was due to increased development activities relating to NVX-CoV2373 for services performed under the U.S. government and Coalition for Epidemic Preparedness Innovations agreements.

Research and development expenses increased to $571 million in the second quarter of 2021, compared to $35 million in the same period in 2020. The increase was primarily due to the development of NVX-CoV2373.

General and administrative expenses increased to $73 million in the second quarter of 2021, compared to $18 million for the same period in 2020. The increase was primarily due to increased employee-related costs, stock-based compensation expenses, and professional fees supporting our NVX-CoV2373 program.

As of June 30, 2021, Novavax had $2.1 billion in cash, cash equivalents and restricted cash, compared to $806 million as of December 31, 2020. Net cash provided by operating activities for the first six months of 2021 was $807 million, compared to $93 million for the same period in 2020. The increase in cash provided was primarily due to $1.1 billion in payments under advance purchase agreements recorded as deferred revenue and the timing of payments to third parties.

Through utilization of At-the-Market (ATM) offerings during the first six months of 2021, Novavax raised net proceeds of $565 million.

About NVX-CoV2373

NVX-CoV2373 is a protein-based vaccine candidate engineered from the genetic sequence of the first strain of SARS-CoV-2, the virus that causes COVID-19 disease. NVX-CoV2373 was created using Novavax' recombinant nanoparticle technology to generate antigen derived from the coronavirus spike (S) protein and is formulated with Novavax' patented saponin-based Matrix-M™ adjuvant to enhance the immune response and stimulate high levels of neutralizing antibodies. NVX-CoV2373 contains purified protein antigen and can neither replicate, nor can it cause COVID-19. In preclinical studies, NVX-CoV2373 induced antibodies that blocked the binding of spike protein to cellular receptors and provided protection from infection and disease. It was generally well-tolerated and elicited robust antibody response in Phase 1/2 clinical testing.

NVX-CoV2373 is being evaluated in two pivotal Phase 3 trials: a trial in the U.K. that demonstrated efficacy of 96.4% against the original virus strain, 86.3% against the Alpha (B.1.1.7) variant and 89.7% efficacy overall; and the PREVENT-19 trial in the U.S. and Mexico that demonstrated 100% protection against moderate and severe disease and 90.4% efficacy overall. It is also being tested in two ongoing Phase 2 studies that began in August 2020: A Phase 2b trial in South Africa that demonstrated 55% efficacy overall in HIV-negative participants and 48.6% efficacy against a newly emerging escape variant first described in South Africa, and a Phase 1/2 continuation in the U.S. and Australia.

NVX-CoV2373 is stored and stable at 2°- 8°C, allowing the use of existing vaccine supply chain channels for its distribution. It is packaged in a ready-to-use liquid formulation in 10-dose vials.

About NanoFlu™

NanoFlu™ is a recombinant hemagglutinin (HA) protein nanoparticle influenza vaccine produced by Novavax in its SF9 insect cell baculovirus system. NanoFlu™ uses HA amino acid protein sequences that are the same as the recommended wild-type circulating virus HA sequences. NanoFlu™ contains Novavax' patented saponin-based Matrix-M™ adjuvant.

About Matrix-M™ Adjuvant

Novavax' patented saponin-based Matrix-M™ adjuvant has demonstrated a potent and well-tolerated effect by stimulating the entry of antigen-presenting cells into the injection site and enhancing antigen presentation in local lymph nodes, boosting immune response.

About Novavax

Novavax, Inc. (Nasdaq: NVAX) is a biotechnology company that promotes improved health globally through the discovery, development and commercialization of innovative vaccines to prevent serious infectious diseases. The company's proprietary recombinant technology platform combines the power and speed of genetic engineering to efficiently produce highly immunogenic nanoparticles designed to address urgent global health needs. Novavax is conducting late-stage clinical trials for NVX-CoV2373, its vaccine candidate against SARSCoV-2, the virus that causes COVID-19. NanoFlu™, its quadrivalent influenza nanoparticle vaccine, met all primary objectives in its pivotal Phase 3 clinical trial in older adults and will be advanced for regulatory submission. Both vaccine candidates incorporate Novavax' proprietary saponin-based Matrix-M™ adjuvant to enhance the immune response and stimulate high levels of neutralizing antibodies.
