Financial Results for the Three and Twelve Months Ended December 31, 2021

Novavax revenue for the fourth quarter and full year ended 2021 were $222 million and $1.1 billion, respectively, compared to $280 million and $476 million for the comparable periods in 2020. The increase to royalties and other revenue in the fourth quarter and full year 2021 was primarily the result of NVX-CoV2373 sales by our license partners to South Korea and Indonesia. The increase to full year 2021 grants revenue reflects the significant NVX-CoV2373 activities funded by both the U.S. government and the Coalition for Epidemic Preparedness Innovations.

Research and development expenses for the fourth quarter and full year ended 2021 were $963 million and $2.5 billion, respectively, compared to $401 million and $747 million for the comparable periods in 2020. The increase was primarily due to the development and manufacturing of NVX-CoV2373, including pre-launch inventory buildup in advance of regulatory authorizations.

General and administrative expenses for the fourth quarter and full year ended 2021 were $84 million and $298 million, respectively, compared to $61 million and $145 million for the comparable periods in 2020.

Net loss for the fourth quarter and full year ended 2021 were $846 million and $1.7 billion, respectively, compared to a net loss of $178 million and $418 million for the comparable periods in 2020.

As of December 31, 2021, Novavax had $1.5 billion in cash, cash equivalents, marketable securities and restricted cash, compared to $0.8 billion as of December 31, 2020.

About NVX-CoV2373

NVX-CoV2373 is a protein-based vaccine 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.

Novavax’ COVID-19 vaccine is packaged as a ready-to-use liquid formulation in a vial containing ten doses. The vaccination regimen calls for two 0.5 ml doses (5 mcg antigen and 50 mcg Matrix-M adjuvant) given intramuscularly 21 days apart. The vaccine is stored at 2°- 8° Celsius, enabling the use of existing vaccine supply and cold chain channels. Use of the vaccine should be in accordance with official recommendations.

Novavax has established partnerships for the manufacture, commercialization and distribution of NVX-CoV2373 worldwide. Existing authorizations leverage Novavax’ manufacturing partnership with Serum Institute of India (SII), the world’s largest vaccine manufacturer by volume. They will later be supplemented with data from additional manufacturing sites throughout Novavax’ global supply chain.

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 harnesses the power and speed of genetic engineering to efficiently produce highly immunogenic nanoparticles designed to address urgent global health needs. NVX-CoV2373, the company’s COVID-19 vaccine, has received conditional authorization from multiple regulatory authorities globally, including the European Commission and the World Health Organization. The vaccine is also under review by multiple regulatory agencies worldwide. In addition to its COVID-19 vaccine, Novavax is also currently evaluating a COVID-seasonal influenza combination vaccine in a Phase 1/2 clinical trial, which combines NVX-CoV2373 and NanoFlu, its quadrivalent influenza investigational vaccine candidate. These vaccine candidates incorporate Novavax’ proprietary saponin-based Matrix-M adjuvant to enhance the immune response and stimulate high levels of neutralizing antibodies.
