FORWARD-LOOKING INFORMATION

This Annual Report on Form 10-K contains forward-looking statements that involve risks and uncertainties. As a result of many factors, such as those set forth under “Risk Factors” and elsewhere in this Annual Report on Form 10-K, our actual results may differ materially from those anticipated in these forward-looking statements. Please also see the disclaimer under the section titled “Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

SUMMARY OF RISKS ASSOCIATED WITH OUR BUSINESS


Our business is subject to numerous risks which are discussed more fully under the heading “Risk Factors” in this Annual Report on Form 10-K. These risks include, but are not limited to, the following:

We have a history of losses and our future profitability is uncertain.

We will continue to require significant funding to maintain our current level of operations and fund the further development of our vaccine candidates.

Because our vaccine product development efforts depend on new and rapidly evolving technologies, we cannot be certain that our efforts will be successful.

The regulatory and commercial success of our COVID-19 vaccine candidate, NVX-CoV2373, remains uncertain. While we have received provisional registration, conditional marketing authorization, or emergency use authorization for NVX-CoV2373 in a number of jurisdictions, we may be unable to obtain regulatory approvals in the United States ("U.S.") or in any other jurisdiction or produce a successful vaccine in a timely manner, if at all.

We are a biotechnology company and face significant risk in developing, manufacturing, and commercializing our products.

Because we depend on third parties to conduct some of our laboratory testing and clinical trials, and a significant amount of our vaccine manufacturing and distribution, we may encounter delays in or lose some control over our efforts to develop and supply products.

Many of our competitors have significantly greater resources and experience, which may negatively impact our commercial opportunities and those of our current and future licensees.

There is significant competition in the development of a vaccine against COVID-19, influenza, and respiratory syncytial virus (“RSV”) and we may never see returns on the significant resources we are devoting to our vaccine candidates.

We may not succeed in obtaining the U.S. Food and Drug Administration (“FDA”) licensure or foreign regulatory approvals necessary to sell our vaccine candidates.

Our products might fail to meet their primary endpoints in clinical trials, meaning that we will not have the clinical data required to support regulatory obligations.

The regulatory pathway for NVX-CoV2373 is continually evolving, and may result in unexpected or unforeseen challenges.
3


We have conducted, are conducting, and plan to conduct in the future, a number of clinical trials for NVX-CoV2373 at sites outside the U.S. and the FDA may not accept data from trials conducted in such locations.

The later discovery of previously unknown problems with a product, manufacturer, or facility may result in restrictions, including withdrawal of a vaccine that had previously received regulatory approval in certain jurisdictions from the market.

Our success depends on our ability to maintain the proprietary nature of our technology.

Our business may be adversely affected if we do not successfully execute our business development initiatives.

Servicing our 3.75% convertible senior unsecured notes due 2023 (the “Notes”) requires a significant amount of cash, and we may not have sufficient cash flow resources to pay our debt.

Because our stock price has been and will likely continue to be highly volatile, the market price of our common stock may be lower or more volatile than expected.

Litigation could have a material adverse impact on our results of operation and financial condition.

We or the third parties upon whom we depend may be adversely affected by natural or man-made disasters or public health emergencies, such as the COVID-19 pandemic.

Overview


Novavax, Inc., together with our wholly-owned Swedish subsidiary,subsidiaries, Novavax AB and Novavax CZ, is a clinical-stage biotechnology company focused onthat promotes improved health globally through the discovery, development and commercialization of recombinant nanoparticleinnovative vaccines and adjuvants. Using innovativeto prevent serious infectious diseases. Our proprietary recombinant nanoparticle vaccine technology weplatform harnesses the power and speed of genetic engineering to efficiently produce highly immunogenic nanoparticles designed to address urgent global health needs.

The vaccine candidates in our near-term pipeline, including both our coronavirus vaccine candidate (“NVX-CoV2373”) and our seasonal quadrivalent influenza vaccine candidate (“NanoFlu”), are genetically engineered, three-dimensional nanostructures of recombinant proteins critical to efficientlydisease pathogenesis. NVX-CoV2373 has received provisional approval, conditional marketing authorization (“CMA”) and effectively respondemergency use authorization (“EUA”) from multiple regulatory authorities globally. In January 2022, we also submitted a request to both knownthe U.S. Food and emerging disease threats.

Drug Administration (“FDA”) for EUA of NVX-CoV2373. We also advanced our NanoFlu Program vaccine program through a Phase 3 clinical trial, which demonstrated positive top-line results and achieved statistical significance in key secondary endpoints. Additionally, we are exploring a number of combination vaccine candidates including a COVID-Influenza combination vaccine currently in a Phase 1/2 clinical trial. We believe that our protein-subunit-based candidates elicit differentiated immune responses that may be more efficacious than naturally occurring immunity or other vaccine approaches. These vaccine candidates incorporate our proprietary saponin-based Matrix-M™ adjuvant to enhance the immune response and stimulate higher levels of neutralizing antibodies.


We were incorporated in 1987 under the laws of the State of Delaware. Our principal executive offices are located at 2021 Firstfield Road, Gaithersburg, Maryland, 20878, and our telephone number is (240) 268-2000. Our common stock is listed on the Nasdaq Global Select Market under the symbol “NVAX.”


NVX-CoV2373 Regulatory and Licensure

We have made substantial progress in advancing NVX-CoV2373 toward regulatory approvals. We have received several authorizations, which collectively have the potential to reach over six billion individuals, and we have completed additional regulatory submissions in other major markets. We are in active discussions with regulatory authorities and remain focused on seeking additional authorizations for NVX-CoV2373. We continue to work closely with governments, regulatory authorities, and non-governmental organizations in our commitment to facilitating equitable global access to our COVID-19 vaccine.

Technology Overview

Recombinant Nanoparticle Vaccine Technology

Our vaccine candidates are genetically engineered three-dimensional nanostructuresrecombinant nanoparticle vaccines combine the power and speed of genetic engineering to efficiently produce a new class of highly immunogenic vaccines that incorporate recombinant proteins critical to disease pathogenesis and may elicit differentiated immune responses, which may be more efficacious than naturally occurring immunity or traditional vaccine. Our product pipeline targetstarget a variety of infectious diseases,viral pathogens.

Once a pathogenic threat has been identified, the genetic sequence encoding the antigen is selected for subsequent use in developing the vaccine construct. The genetic sequence may be optimized to enhance protein stability or confer resistance to degradation. This genetic construct is inserted into the baculovirus Spodoptera frugiperda (Sf9/BV) insect cell-expression system, which enables efficient, large-scale expression of the optimized protein. The Sf9/BV system produces proteins that are properly folded and modified – which can be critical for functional, protective immunity – as the vaccine antigen. Protein antigens are purified and organized around a polysorbate-based nanoparticle core, in a configuration that resembles their native presentation. This presentation results in a highly immunogenic nanoparticle that is ready to be formulated with clinicalMatrix-M adjuvant. We believe our vaccine technology is well-suited for the development of additional vaccine candidates againsttargeting a broad scope of respiratory syncytial virusand other emerging infectious diseases.

Matrix-M Adjuvant

Our proprietary Matrix-M™ adjuvant has been a key differentiator within our platform. This adjuvant has demonstrated potent and well-tolerated efficacy by stimulating the entry of antigen presenting cells (“RSV”APCs”), influenza into the injection site and Ebola virus (“EBOV”),enhancing antigen presentation in local lymph nodes, which in turn activates APC cells, T-cells, and preclinical programs for other infectious disease vaccine candidates.

We are also developingB-cell populations, thereby boosting immune stimulating saponin-based adjuvants through our wholly owned Swedish subsidiary, Novavax AB. Our leadresponse. Matrix-M™ adjuvant Matrix-M™, has been shown to enhanceproduce a long-lasting memory response, through the production of plasma cells, memory B-cells, high affinity antibodies, and CD4+ T-cells. This potent mechanism of action enables a lower dose of antigen required to achieve the desired immune responsesresponse and was well-toleratedwe believe thereby contributes to increased vaccine supply and manufacturing capacity. These immune-boosting and dose-sparing capabilities contribute to the adjuvant’s highly unique profile.


We continue to evaluate commercial opportunities for the use of our Matrix-M™ adjuvant alongside vaccine antigens produced by other manufacturers. Matrix-M™ is being evaluated in combination with several partner-led malaria vaccine candidates, including in a Phase 3 trial for R21, a malaria vaccine candidate created by the Jenner Institute, University of Oxford. The University of Oxford has partnered with SIIPL for commercial development of R21 and has granted SIIPL a license for R21. We expect to manufacture and supply the Matrix-M™ adjuvant component of R21 to SIIPL, which represents a significant commercial opportunity for our adjuvant, pending possible licensure. We have commercial rights to sell and distribute the SIIPL-manufactured R21 in certain countries, primarily in the travelers’ and military vaccine markets.

We are also supplying Matrix-M™ adjuvant for two Phase 1 clinical trials led by National Institutes of Health teams, focused on Epstein-Barr virus and Malaria transmission blocking.

Pipeline Overview

Our development pipeline encompasses vaccine candidates spanning multiple therapeutic areas, with our COVID-19 vaccine candidate, NVX-CoV2373, as the leading product candidate, which has received provisional registration, CMA, or EUA in a number of jurisdictions. We have also submitted a request to the FDA for EUA of NVX-CoV2373. Beyond COVID-19, our pipeline includes programs for seasonal influenza, a combination vaccine consisting of NanoFlu and NVX-CoV2373,RSV, and Matrix-MTM adjuvant collaborations for the treatment of malaria. We advanced NVX-CoV2373 through two pivotal Phase 3 clinical trials that we have conducted.

Product Pipeline

Our product pipeline includesdemonstrated high efficacy against both the original COVID-19 strain and commonly circulating COVID-19 variants of concern (“VoC”), while maintaining a favorable safety profile. We also advanced our NanoFlu Program through a Phase 3 clinical trial, which demonstrated positive top-line results and achieved statistical significance in key secondary endpoints. We initiated a trial of a combination vaccine candidates engineered to elicit differentiated immune responses with the potential to provide increased protection. Our nanoparticle technology targets antigens with conserved epitopes essential for viral function. Our vaccine technology has the potential to be applied broadly to a wide variety of human infectious diseases.

Respiratory Syncytial Virus

We have identified three susceptible target populations that could benefit from thefurther development of our RSV Program for respiratory syncytial virus fusion (F) protein nanoparticle vaccine candidate (“RSV F Vaccine”). Ongoing Phase 3 trials are being conducted for R21, a malaria candidate, by our partners, Jenner Institute, University of Oxford, which is formulated with our Matrix-M adjuvant.


We remain focused on bringing our NVX-CoV2373 vaccine candidate to market following global regulatory authorizations. Through ongoing booster studies in our clinical trials, as well as the development of COVID-19 variant strain vaccine candidates, we continue to collect data to characterize and improve vaccine performance. We expect to leverage these clinical insights to advance the use and additional regulatory approvals of our COVID-19 vaccine for both primary

vaccination around the globe, to use within a booster setting, and for the pediatric population amidst the ongoing and evolving COVID-19 pandemic.

Although NVX-CoV2373 and our NanoFlu Program are our near-term priorities, we remain optimistic that the additional programs in our pipeline, including our RSV Program, and our partner-led malaria candidate, present strong opportunities for future development.

Coronavirus

NVX-CoV2373 Clinical Development

NVX-CoV2373 has progressed through multiple clinical trials, including two Phase 3 trials, one Phase 2b trial, and one Phase 1/2 trial. We have completed crossover arms in our Phase 3 UK, Phase 2b South Africa, PREVENT-19 Phase 3 U.S. and Mexico, and PREVENT-19 pediatric expansion trials. Through our clinical development program to date, we have established a dose of 5 micrograms of NVX-CoV2373 with Matrix-M adjuvant for late-stage development. We have collected data that indicates a reassuring safety profile and statistically significant levels of efficacy for NVX-CoV2373 against the original COVID-19 strain and commonly circulating VOC.

A summary and status of our clinical development of NVX-CoV2373 by trial is as follows:

PREVENT-19 Phase 3 U.S. and Mexico

PREVENT-19 was a randomized, placebo-controlled, observer-blinded Phase 3 trial to evaluate the efficacy, safety, and immunogenicity of NVX-CoV2373 in 29,960 participants aged 18 years or older across 119 sites in the U.S. and Mexico. Enrollment for PREVENT-19 emphasized recruiting high-risk groups most impacted by COVID-19.

In December 2021, the full results from the PREVENT-19 Phase 3 trial in the U.S. and Mexico were published in The New England Journal of Medicine. The analysis, previously announced in June 2021, was conducted on events accrued prior to participants receiving crossover vaccine. NVX-CoV2373 achieved 100% protection against moderate and severe disease, 92.6% efficacy against any VOC and variants of interest (“VOI”), and the primary endpoint of 90.4% efficacy against COVID-19 of any severity during the time period evaluated, despite the majority (79%) of the sequenced cases of illness being attributed to VOC and VOI. PREVENT-19 was conducted with support and funding from OWS.

In November 2021, the U.S. Centers for Disease Control and Prevention (“CDC”) provided guidance stating that our PREVENT-19 participants from sites outside the U.S., as well as previously stated guidance stating participants from within the U.S., are considered fully vaccinated. In January 2022, we also submitted a request to the FDA for EUA of NVX-CoV2373.

PREVENT-19 Pediatric Expansion

In February 2022, we announced positive results from our Phase 3 PREVENT-19 pediatric expansion in adolescents aged 12 to 17, for which we completed enrollment in June 2021. The study results achieved their primary effectiveness endpoint and demonstrated 80% efficacy overall, with 82% clinical efficacy against the Delta (B.1.617.2) variant, as the trial was conducted when the Delta (B.1.617.2) variant was the predominant circulating strain in the U.S. Immune responses were two-to-three-fold higher in adolescents than in adults against all variants studied. NVX-CoV2373 was well-tolerated with no safety signals identified.

The study enrolled 2,247 adolescents across 73 sites in the U.S. to evaluate safety, effectiveness (immunogenicity), and efficacy, with an emphasis on ensuring well-balanced racial and ethnic representation among participants. Participants randomly received either the vaccine candidate or placebo in two doses, administered 21 days apart. Two-thirds of participants received intramuscular injections of the vaccine and one-third received placebo. Participants are being monitored for safety for up to two years following the final administered dose.

We expect to submit our regulatory filing to global regulatory authorities during the first quarter of 2022. The subsequent pediatric clinical development plan has been agreed to by the FDA, the MHRA, and EMA and we expect to initiate additional studies globally evaluating younger age groups during the second quarter of 2022.

In December 2021, we announced initial data evaluating the immune response of NVX-CoV2373 against the Omicron (B.1.1.529) variant strain from our ongoing PREVENT-19 pediatric expansion. Data from this study showed immune responses in adolescents were 2- to 4-fold higher than adults against broad array of variants of interest and variants of concern.
10


Phase 3 UK

In February 2022, we announced extended analysis from our pivotal Phase 3 UK trial showing that a high level of efficacy for NVX-CoV2373 was maintained over a 6-month period of surveillance. The analysis showed vaccine efficacy of 82.5% in protection against all COVID-19 infection, both symptomatic and asymptomatic, as measured by PCR+ or anti-N seroconversion. NVX-CoV2373 showed a reassuring safety profile during over the 6-month period, with adverse events that were balanced between vaccine and placebo groups. Additionally, the trial demonstrated continued protection with an overall vaccine efficacy of 82.7% and vaccine efficacy against severe disease was 100% during the 6-month efficacy collection window, in line with the initial analysis.

This data builds upon the final analysis of our Phase 3 UK trial was published in The New England Journal of Medicine in June 2021. The publication of the final analysis highlights the robust safety and efficacy data for NVX-CoV2373. The final analysis confirmed 89.7% overall efficacy, with over 60% of the cases caused by the Alpha (B.1.1.7) variant strain. The analysis also confirmed 96.4% efficacy against non-Alpha (non-B.1.1.7) variant strains present at the time of the study, which represents strains most similar to the original COVID-19 virus. The trial was a randomized, observer-blinded, placebo-controlled study that enrolled 15,203 adults aged 18 to 84. The trial was conducted in partnership with the UK government Vaccines Taskforce (“VTF”) and led by researchers at St George’s, University of London, and St George’s Hospital, London.

In June 2021, the National Health Service (“NHS”), UK government VTF, and National Institute for Health Research determined participants in our Phase 3 UK trial may be considered fully vaccinated under the standard NHS program.

Phase 3 UK Influenza Co-Administration Sub-Study

In November 2021, positive results from our Phase 3 UK influenza co-administration sub-study, the first co-administration study of a SARS-CoV2 vaccine candidate and an approved influenza vaccine were published in The Lancet Respiratory Medicine. In the sub-study, with initial data announced in June 2021, 431 participants from our Phase 3 UK trial received an approved seasonal influenza vaccine (Seqirus, adjuvanted, trivalent seasonal influenza vaccine or a cell-based quadrivalent seasonal influenza vaccine). Approximately half of the participants in the study were co-vaccinated with NVX-CoV2373, while the remainder received placebo. Results demonstrated a robust immune response and a favorable safety and reactogenicity profile. Immunogenicity of the influenza vaccine was preserved with concomitant administration, while a modest decrease in the immunogenicity of NVX-CoV2373 was found. There was an adequate number of participants aged 18 to 64 years to confirm an efficacy trend of 87.5% against COVID-19. The co-administration sub-study represents the first study of a SARS-CoV-2 vaccine candidate and an approved influenza vaccine, and was led by researchers at St George’s, University of London and St George’s Hospital, London.

Phase 2b South Africa

In May 2021, results from the initial primary analysis of our Phase 2b South Africa trial were published in The New England Journal of Medicine. The publication of the initial primary analysis, which was previously announced in January 2021, highlights NVX-CoV2373’s cross-protection against the Beta (B.1.351) variant strain prevalent in South Africa during the study.

The Phase 2b South Africa trial was a randomized, observer-blinded, placebo-controlled study that enrolled 4,404 participants. Half of the trial participants received two intramuscular injections of NVX-CoV2373, administered 21 days apart, while the other half of the trial participants received placebo.

In the complete analysis announced in March 2021, NVX-CoV2373 demonstrated 55.4% efficacy for the prevention of mild, moderate, and severe COVID-19 disease in the 95% of the trial population that was HIV-negative. Overall efficacy, including both HIV-positive and HIV-negative participants, was 48.6% predominantly against the Beta (B.1.351) variant strain, with the complete analysis showing that NVX-CoV2373 achieved its primary efficacy endpoint in the overall trial population. During the efficacy analysis, the Beta (B.1.351) variant strain circulating in South Africa accounted for approximately 93% of sequenced cases in our Phase 2b trial. There were no cases of severe disease in the NVX-CoV2373 group, and all hospitalization and death occurred in the placebo group. This trial also showed that the vaccine is well-tolerated, with low levels of serious adverse events, or SAEs, through day 35, balanced between vaccine and placebo groups. CEPI funded the manufacturing of doses of NVX-CoV2373 for this Phase 2b clinical trial, which was also supported in part by a $15.0 million grant from BMGF.

NVX-CoV2373 Clinical Development Conducted by Partners

Phase 2/3 India

SIIPL has expanded their Phase 2/3 clinical trial of NVX-CoV2373 in India to include a pediatric cohort. In the pediatric cohort, SIIPL has initiated recruitment of participants aged 2-17 years, with the intention of completing enrollment of 920 total participants. Previously, in April 2021, SIIPL completed enrollment of approximately 1,600 participants aged 18 years and older in their initial cohort. This study, which was initiated in March 2021, will evaluate the safety and immune response of NVX-CoV2373.

Phase 1/2 Japan

In March 2021, Takeda completed enrollment of a Phase 1/2 clinical trial of NVX-CoV2373 in Japan. This placebo-controlled trial will evaluate the immunogenicity and safety of NVX-CoV2373 in 200 participants aged 20 years and older. The interim clinical study report has been completed with the safety and immunogenicity data needed to support the Japan Pharmaceuticals and Medical Device Agency application. Participants are currently in their twelve-month safety follow-up.

Variant Strain (Monovalent and/or Bivalent) Vaccine Development

Our nanoparticle vaccine technology is purpose-built to rapidly address evolving infectious disease threats. As variants of COVID-19 emerge, we proactively evaluate NVX-CoV2373’s ability to protect against variant strains and evaluate the potential need for variant-specific vaccine constructs.

COVID-19 Omicron (B.1.1.529) Variant Strain Vaccine

In December 2021, we began development of an Omicron-specific vaccine construct of the SARS-CoV-2 Spike protein (rS) antigen, currently in use in NVX-CoV2373, and initiated GMP manufacturing. We expect delivery towards the end of the first quarter of 2022.

NVX-CoV2373 Booster Studies

PREVENT-19 Booster Study

In December 2021, we initiated PREVENT-19 Phase 3 trial booster study for NVX-CoV2373. The study will evaluate the safety the safety and efficacy of a heterologous or homologous third dose of NVX-CoV2373. All the PREVENT-19 trial participants are eligible to receive a third booster dose. The booster dose is identical to the active vaccine previously administered to the participants in a two-dose regimen (5 micrograms of recombinant Spike protein plus 50 micrograms of Matrix-M™ adjuvant) and may be administered at least six months after receipt of active vaccine. The primary endpoint is the first occurrence of polymerase chain reaction (PCR)-confirmed mild, moderate or severe COVID-19 with onset at least seven days after the third (booster) vaccine dose. Two additional groups will be evaluated in this portion of the trial. Trial participants who initially received placebo and subsequently received a different formulations: infantsCOVID-19 vaccine are also eligible for a booster dose of NVX-CoV2373. Participants who were unblinded after initially receiving active vaccine and did not subsequently receive another vaccine will also be eligible to be boosted with NVX-CoV2373.

Phase 2 U.S. and Australia Booster Study - Including Omicron (B.1.1.529) Variant Results

In December 2021, we announced initial data evaluating the immune response of NVX-CoV2373 against the Omicron (B.1.1.529) variant strain as well as additional data from our ongoing Phase 2 booster study. These results demonstrated broad cross-reactivity against the Omicron variant and other circulating variants for primary 2-dose regimen, with enhanced responses following a third dose at six months. The third dose produced increased immune responses to the Omicron (B.1.1.529) variant strain comparable to or exceeding levels associated with protection in Phase 3 clinical trials, with a 9.3-fold IgG rise and a 19.9-fold increase in hACE2 inhibition increase after booster dose. Data from this study are available ahead of publication via maternal immunization, older adults (60 yearsthe preprint server for biology on medRxiv.

In September 2021, we initiated a twelve-month booster dose for select participants in the Phase 2 portion of ageour U.S. and older)Australia Phase 1/2 trial. Select participants received a fourth 5 microgram dose at twelve months to examine the immune responses produced by our vaccine candidate.

In August 2021, we announced data from our six-month booster study in the Phase 2 portion of our U.S. and childrenAustralia Phase 1/2 trial, which we initiated in March 2021. Select participants in the 5 microgram dose cohort received a third 5 microgram dose (booster dose) at six months to fiveexamine the immune responses of our vaccine candidate. Analysis of sera from primary vaccination series notably showed cross-reactive, functional antibodies to Alpha (B.1.1.7), Beta (B.1.351) and Delta (B.1.617.2) variant spike proteins, all of which increased 6- to 10-fold with the booster dose.

NVX-CoV2373: Partner-Led Vaccine Mix and Match Clinical Study

Mix-and-MatchCOVID-19 Vaccine BoosterTrial ("Cov-Boost") – Led by University Hospital Southampton NHS

In December 2021, the UK government VTF announced top-line data from the heterologous boosting, Phase 2 Cov-Boost study published in The Lancet from the University Hospital Southampton NHS Foundation Trust. NVX-CoV2373 was one of seven COVID-19 vaccines studied for the potential to provide a booster dose from a different manufacturer for individuals who previously received two doses of an authorized vaccine. The results demonstrated that administration of NVX-CoV2373 among other studied COVID-19 vaccines, resulted in substantial increases in functional antibody titers when given as a third dose in two heterologous vaccination regiments. This study reinforces our confidence in the potential for NVX-CoV2373 to serve as a well-tolerated third dose to boost immune levels and provide broad protection against disease without a burdensome side effect profile.
The trial, which was initiated in June 2021, completed enrollment in July of 2,886 participants aged 30 years and older. NVX-CoV2373 is one of age (“pediatrics”seven COVID-19 vaccines evaluating the potential for providing a booster dose from different manufacturers to individuals who have previously received two doses of an authorized vaccine. The trial assesses the safety and immune response against COVID-19 provided by the various vaccine schedules. The trial is led by the University Hospital Southampton NHS Foundation Trust and other UK National Institute for Health Research sites. Cov-Boost is receiving support from the UK government VTF and Department of Health and Social Care.

COVID-19 Vaccine Funding

We have secured critical funding to support the development of NVX-CoV2373. Through the date of filing this Annual Report on Form 10-K, funding for NVX-CoV2373 encompasses over $2 billion from sources including CEPI, DoD, and OWS.

In April 2021, our Base Agreement and a Project Agreement (together, as amended and supplemented, the “OWS Agreement”) entered into with Advanced Technology International, Inc., the Consortium Management Firm acting on behalf of the Medical CBRN Defense Consortium in connection with OWS, was amended to fully fund the agreement up to $1.75 billion to support certain activities related to the development of NVX-CoV2373. This includes the manufacture and delivery of 100 million doses of NVX-CoV2373 to the U.S. government. We expect this funding will assist in rapidly developing our large-scale manufacturing capacity and transitioning into ongoing production, including the capability to stockpile and distribute large quantities of NVX-CoV2373 for use in clinical trials and for commercial sale. The OWS Agreement is funding the late-stage clinical studies necessary to determine the safety and efficacy of NVX-CoV2373, including PREVENT-19. Funding under the OWS Agreement supported our file submission for EUA with the FDA and is expected to support our plans to submit a BLA with the FDA. Accepted analytical methods that we can use to demonstrate our vaccine’s purity, potency, and consistent lot manufacturing are critical to attaining licensure in all the territories we intend to sell our vaccine. In the U.S., these analytical methods will be reviewed and approved by the FDA. As of December 31, 2021, the Company's OWS agreement was amended to increase the contract ceiling by $52.9 million for a revised total of $1.8 billion. The agreement’s authorized funding and scope remains unchanged at $1.75 billion for support of certain activities related to the development of NVX-CoV2373 and the manufacture and delivery of 100 million doses of the vaccine candidate to the U.S. government. The Company and the U.S. government will determine the timing and amounts for delivery of NVX-CoV2373 doses upon U.S authorization and the Company intends to pursue additional U.S. procurement agreements for supply of NVX-CoV2373 doses. In July 2021, the U.S. government instructed us to prioritize alignment with the FDA on our analytic methods before conducting additional U.S. manufacturing and further indicated that the U.S. government will not fund additional U.S. manufacturing until such agreement has been made. The U.S. government also instructed us to proceed with work under the OWS Agreement related to all other activities including ongoing clinical trials and nonclinical studies, regulatory interactions, analytics/assays, and characterization of manufactured vaccine and project management.In October 2021 and January 2022, the U.S. government extended the prescribed time to meet its July 2021 instructions until April 2022.

In February 2022, the Company’s Project Agreement with ATI was modified to include a Phase 3 efficacy study with respect to 2019n-CoV-301 in adolescents with a booster component and accordingly, the performance period under the Project Agreement was extended to December 31, 2023.

Seasonal Influenza

NanoFlu Program (Older Adults)

Influenza is a world-wide infectious disease with serious illness generally occurring in more susceptible populations such as children under and older adults, but also occurring in the general population. According to a 2021 Fortune Business Insights research report forecast of influenza vaccines, the market for seasonal influenza vaccines is expected to grow from approximately $6.6 billion in 2021 to approximately $10.73 billion in 2028.

In September 2021, the final analysis of the primary endpoint of our pivotal Phase 3 clinical trial for the NanoFlu Program was published in The Lancet Infectious Diseases. We believepreviously announced that the NanoFlu Program achieved the trial’s primary endpoints, demonstrating non-inferior immunogenicity to Fluzone® Quadrivalent against all four influenza virus strains included in the vaccine, while also showing both enhanced wild-type hemagglutination-inhibiting antibody responses against homologous strains (22-66% increased) and six heterologous A/H3N2 strains (34-46% increased) as compared to Fluzone® Quadrivalent. Additionally, the NanoFlu Program showed potent induction of polyfunctional antigen-specific CD4+ T-cells against A(H3N2) and B/Victoria strains, with a 126–189% increase in various post vaccination cell-mediated immunity markers as compared to Fluzone® Quadrivalent.

Combination Vaccines

Our NanoFlu Program team remains focused on advancing combination vaccine candidates. With the ongoing development of NanoFlu Program, NVX-CoV2373, and our RSV FProgram, a strong rationale exists for developing combination respiratory vaccines designed to protect susceptible populations against these diseases.

COVID / Influenza Combination Vaccine represents

Phase 1/2 Clinical Trial of COVID-Influenza Combination Vaccine

In October 2021, we completed enrollment of our Phase 1/2 study in Australia, which we initiated in September 2021. The trial enrolled 642 healthy adults aged 50 to 70 years across 10 sites and will evaluate the safety, tolerability and immune response of a multi-billion dollar revenue opportunity, worldwide. combination vaccine using NanoFlu Program and NVX-CoV2373, combined with our Matrix-M™ adjuvant. Participants have been either previously infected with the SARS-CoV-2 virus that causes COVID-19 or vaccinated through an authorized vaccine at least eight weeks prior to enrollment. All participants will be randomly assigned to cohorts to evaluate multiple formulations and will be administered doses on Day 0 and again at Day 56. Data from this Phase 1/2 trial are expected in the second quarter of 2022. Data from this Phase 1/2 trial are expected in April of 2022. We expect to initiate a Phase 2 clinical trial for the COVID-Influenza combination vaccine and NanoFlu Program as a standalone vaccine in the second half of 2022.

14

In May 2021, we announced data from a preclinical study of qNIV/CoV2373 to assess its immunogenicity and protective efficacy in animal models. Preclinical data from this study showed that qNIV/CoV2373 induced functional influenza and COVID-19 antibody responses, with hemagglutination inhibition and ACE2 receptor-inhibiting titers that were comparable between immunization with the combination vaccine and with its respective component vaccines. qNIV/CoV2373 also induced elevated levels of SARS-CoV-2 anti-S IgG two weeks after the first immunization, which increased significantly after the second dose, with levels comparable to animals that received NVX-CoV2373 alone. Human ACE2 receptor inhibiting antibody levels responded similarly. qNIV/CoV2373 also induced antibodies against SARS-CoV-2 neutralizing epitopes that are common between the original COVID-19 strain and the Beta (B.1.351) variant strain. When challenged with SARS-CoV-2, examination of viral load in the upper and lower respiratory tract showed little or no virus was detected four days after infection in animals immunized with either qNIV/CoV2373 or with NVX-CoV2373 alone. Data from this study are available ahead of publication via the preprint server for biology on bioRxiv.

Respiratory Syncytial Virus ("RSV")

Currently, there is no approved RSV vaccine available.

1

Repeat infection and lifelong susceptibility to RSV are common and we currently estimate the global cost burden of RSV to be in excess of $88 billion.1 Despite decades of effort to develop an RSV vaccine, there are currently no licensed vaccines. We made a breakthrough in developing a vaccine that targets the fusion protein, or F-protein, of the virus. The F-protein has highly conserved amino acid sequences, called antigenic sites, which we believe are ideal vaccine targets. We genetically engineered a novel F-protein antigen resulting in enhanced immunogenicity by exposing a number of these antigenic sites. The Novavax RSV F Vaccine assembles into a recombinant protein nanoparticle optimized for F-protein antigen presentation. We are seeking to bring the first RSV vaccine to marketavailable to combat the estimated 64 million RSV infections that occur globally each year.2,3

RSV Infants via Maternal Immunization Program

Burden of Disease

RSV is the most common cause of lower respiratory tract infections and the leading viral cause of severe lower respiratory tract disease in infants and young children worldwide.4,5 In the U.S., RSV is the leading cause of hospitalization of infants, and globally, is second only to malaria as a cause of death in children under one year of age.6,7 Despite the induction of post-infection immunity, repeat infection and lifelong susceptibility to RSV is common.8,9

Clinical Trial Update

Prepare Phase 3 Trial (Ongoing)

We initiated Prepare™, a global pivotal Phase 3 clinical trial of our RSV F Vaccine, using aluminum phosphate as an adjuvant, in approximately of 4,600 healthy pregnant women in December 2015. The primary objective of the Prepare trial is to determine the efficacy of maternal immunization with the RSV F Vaccine against symptomatic RSV lower respiratory tract infection with objective measures of medical significance in infants through a minimum of the first 90 days of life and up to the first six months of life.

The Prepare trial utilizes a group sequential design. We will initiate a prescribed interim efficacy analysis when we have approximately 4,600 enrolled women, currently expected in mid-2018, and report results from this interim analysis, expected in early 2019. Assuming successful interim analysis results, the trial would be concluded without further enrollment. In 2017, with approximately 1,300 participants in the Prepare trial, we conducted an informational analysis that provided a positive indication of our vaccine’s potential efficacy (between 45% and 100%10), further de-risking this important program. These results have allowed us to make go-forward decisions relating to various program-related activities.

The Prepare trial is supported by a grant (the “Grant”) of up to $89.1 million from BMGF. The Grant supports development activities, product licensing efforts and World Health Organization (“WHO”) prequalification of our RSV F Vaccine. In 2015, along with the Grant agreement (the “Grant Agreement”), we concurrently entered into a Global Access Commitments Agreement with BMGF, under which we agreed to make a certain amount of the RSV F Vaccine available and accessible at affordable pricing to people in certain low and middle income countries.

Phase 2 Safety and Immunogenicity Trial (Completed)

In September 2015, we announced positive top-line data from our Phase 2 clinical trial of our RSV F Vaccine in 50 healthy pregnant women and their infants. This clinical trial evaluated the safety and immunogenicity of our RSV F Vaccine in pregnant women in their third trimester, and assessed the transplacental transfer of maternal antibodies induced by the vaccine. The trial also examined the impact of maternal immunization on infant safety during the first year of life and RSV-specific antibody levels through the infants’ first six months of life. Immunized women demonstrated a geometric mean 14-fold rise in anti-F IgG, a 29-fold rise in palivizumab-competing antibodies and 2.7 and 2.1-fold rises in microneutralization titers against RSV/A and RSV/B, respectively. In contrast, women who received placebo demonstrated no significant change in antibody levels. The infants’ antibody levels at delivery averaged 90-100% of the mothers’ levels, indicating efficient transplacental transfer of antibodies from mother to infant. The estimated half-lives of infant PCA, anti-F IgG, and RSV/A and RSV/B microneutralizing antibodies, based on data through day 60, were 41, 30, 36 and 34 days, respectively.

Fast Track Designation

The U.S. Food and Drug Administration (“FDA”) granted Fast Track designation to our RSV F Vaccine for protection of infants via maternal immunization. Fast Track designation is intended for products that treat serious or life-threatening diseases or conditions, and that demonstrate the potential to address unmet medical needs for such diseases or conditions. The program is designed to facilitate development and expedite review of drugs to treat serious and life-threatening conditions so that approved products can reach the market expeditiously.

RSV Older Adults Program

Burden of Disease

Older adults (60 years of age and older) are at increased risk for RSV disease due in part to immunosenescence, the age-related decline in the human immune system. In this population, RSV is an important respiratory virus, distinct from influenza, which is frequently responsible for serious lower respiratory tract disease and may lead to hospitalization or even death. Additionally, RSV infection can also lead to exacerbation of underlying co-morbidities such as chronic obstructive pulmonary disease, (“COPD”), asthma and congestive heart failure. In the U.S., the incidence rate is approximately 2.5 million infections per year, and


RSV is increasingly recognized asProgram (Older Adults)

Clinical Trial Updates and Analyses

Phase 2 (E-205) Safety and Immunogenicity Clinical Trial (Completed)

In July 2017, we announced positive top-line data from our Phase 2 clinical trial ofdemonstrated that our RSV F Vaccine inProgram for older adults known as E-205. The objective of the E-205 trial was to assess safety and immunogenicity to one and two dose regimens of the RSV F Vaccine, with and withouteither aluminum phosphate or our proprietary Matrix-MTM adjuvant in older adults. The trial was a randomized, observer-blinded, placebo-controlled trial which enrolled 300 older adults in the Southern Hemisphere. Participants were enrolled and vaccinated outside of the RSV season to best assess immunogenicity. Immunogenicity results indicated both aluminum phosphate and Matrix-M adjuvants increased the magnitude, duration and quality of the immune response relative to RSV F antigen alone. All formulations and regimens were safe and well-tolerated. The data supportversus the inclusion of adjuvanted formulations of our RSV F Vaccine in future older adult trials, although we do not currently expect to initiate such trials in 2018 without additional funding.

Further Analyses of Prior Clinical Trials

Following the September 2016 announcement of top-line results of Resolve™, our Phase 3 clinical trial of our RSV F Vaccine in older adults conducted during the 2015-16 RSV season in the U.S., we conducted multiple analyses on the clinical data from the Resolve trial, as well as the other completed Phase 2 clinical trials conducted in older adults. Our analyses of these clinical trials sought to better understand their results. More detailed descriptions of each of these RSV older adult clinical trials are found under “Clinical Trial Updates and Analyses” below; the trials are named and briefly described in the following table:

Clinical Trial Name Phase Description Conducted Participants(#)
E-201 Phase 2 Efficacy in prevention of all symptomatic RSV disease 2014-15 RSV season 1,600
Resolve (or E-301) Phase 3 Efficacy in prevention of msLRTD 2015-16 RSV season 11,856
E-202 Rollover Phase 2 Immunogenicity in response to serial immunization after E-201 2015-16 RSV season 1,329
E-205 Phase 2 Immunogenicity in one or two doses, with or without adjuvant 2017 300

We have found that seasonal variation in attack rate, meaning the incidence of infectious disease in an at-risk population, may have a large impact on demonstrating vaccine efficacy in a particular year. Lower attack rates may mean that either the virus is less common in a given season, or alternatively, that the population being studied has increased intrinsic resistance in that season due to a variety of potential factors such as recent prior exposure. In our E-201 trial, we witnessed a high attack rate and showed a clear demonstration of efficacy. In our Resolve trial the following year, we observed a primary endpoint attack rate of only one-fourth that of the previous season. This scenario represents a conundrum that influenza vaccine developers have experienced for decades: “low attack rate” influenza seasons make it very difficult to demonstrate vaccine efficacy.

Additional further analyses of the Resolve trial data indicate that our RSV F Vaccine was associated with a 61% reduction in hospitalizations due to COPD exacerbations, and the same analysis of the E-201 trial showed a similar signal, supporting this finding. We believe that such higher-risk patients represent an unmet medical need with a significant healthcare cost burden that could potentially be addressed by such a vaccine.

Resolve (E-301) Phase 3 Trial (Completed)

In September 2016, we announced top-line data from our Resolve trial. Resolve was a randomized, observer-blinded, placebo-controlled trial that began in November 2015, and was fully enrolled with 11,856 older adults at 60 sites in the U.S. by December 2015. The trial did not meet its pre-specified primary or secondary efficacy objectives and did not demonstrate vaccine efficacy. The primary objective of the Resolve trial was to demonstrate efficacy in the prevention of moderate-severe RSV (“msLRTD”), as defined by the presence of multiple lower respiratory tract symptoms. The secondary objective of the trial was to demonstrate efficacy of the RSV F Vaccine in reducing the incidence of all symptomatic respiratory disease due to RSV ARD. The trial also evaluated the safety of an unadjuvanted, 135 microgram dose of the RSV F Vaccine compared to placebo. Consistent with our previous clinical experience, the vaccine was well-tolerated.

4

Phase 2 (E-202) Rollover Trial (Completed)

In September 2016, we announced positive top-line data from our E-202 rollover trial of our RSV F Vaccine in older adults. The trial was a randomized, observer-blinded, placebo-controlled rollover trial, which enrolled 1,329 older adults from our prior E-201 trial, conducted at the same 10 sites in the U.S. as the E-201 trial. The primary objectives of the trial were to evaluate safety and serum anti-F IgG antibody concentrations in response to immunization with thenon-adjuvanted RSV F Vaccine. The exploratory objectives of the trial evaluated the efficacy of a second annual dose of the RSV F Vaccine in the prevention of RSV ARD and RSV msLRTD. Participants previously randomized to receive 135 microgram RSV F Vaccine or placebo were re-enrolled and re-randomized to receive either 135 microgram RSV F Vaccine or placebo. This trial design resulted in four separate trial arms: a) participants receiving a placebo in both the first trial and second trial (“Placebo-Placebo”); b) participants receiving RSV F Vaccine in the first trial and placebo in the second trial (“Vaccine-Placebo”); c) participants receiving placebo in the first trial and RSV F Vaccine in the second trial (“Placebo-Vaccine”); and d) participants receiving RSV F Vaccine in both the first trial and second trial (“Vaccine-Vaccine”).

The E-202 rollover trial demonstrated immunogenicity in all active vaccine recipients, with a 6-fold increase in anti-F IgG in the Placebo-Vaccine arm, consistent with the E-201 trial. There was higher anti-F IgG at baseline in the Vaccine-Vaccine arm compared to the Placebo-Vaccine arm and the Vaccine-Vaccine arm showed a greater than 2-fold increase in anti-F IgG from the higher baseline.

Phase 2 (E-201) Trial in Older Adults (Completed)

In August 2015, we announced positive top-line data from our E-201 trial of our RSV F Vaccine in 1,600 older adults. The E-201 trial was designed to prospectively examine the incidence of all symptomatic respiratory illnesses associated with RSV infection, in community-living older adults who were treated with placebo. The trial also evaluated safety and immunogenicity of our RSV F Vaccine compared to placebo. Finally, the trial estimated the efficacy of our RSV F Vaccine in reducing the incidence of respiratory illness due to RSV. The trial was the first to demonstrate efficacy of an active RSV immunization in any clinical trial population. In the per protocol population, the clinical trial showed statistically significant vaccine efficacy in prevention of all symptomatic RSV disease (41%) and, in an ad hoc analysis, showed a decrease in RSV disease with any symptoms of lower respiratory tract infection (45%) in older adults. The clinical trial established an attack rate for symptomatic RSV disease of 4.9% in older adults, 95% of which included lower respiratory track symptoms. Efficacy against more severe RSV illness, defined by the presence of multiple lower respiratory tract symptoms or signs associated with difficulty breathing, was 64% in ad hoc analyses.

RSV Pediatrics Program

Burden of Disease

There are currently approximately 18 million children in the U.S. between six months and five years of age.17 By the age of five, essentially all children will have been exposed to RSV and will likely have developed natural immunity against the virus, thus decreasing the rate of severe disease in these children. In the U.S., RSV is responsible for approximately 57,000 hospitalizations of children under five years of age annually, the vast majority of which occur in infants less than one year old, and especially those under six months of age.18,19,20,21,22

Clinical Trial Update

In September 2015, we announced positive top-line data from our Phase 1 clinical trial of our RSV F Vaccine in healthy children between two and six years of age. This clinical trial evaluated the safety and immunogenicity of our RSV F Vaccine, with one or two doses, with or without aluminum phosphate adjuvant. Trial enrollment was concluded with a smaller than planned cohort so that dosing could be completed ahead of the 2014-15 RSV season. The vaccine was well-tolerated and serum samples collected from a subset of 18 immunized children in the per-protocol population, demonstrated that the RSV F Vaccine was highly immunogenic at all formulations and regimens. There were greater than 10-fold increases in both anti-F IgG and PCA antibody titers in the adjuvanted group and greater than 6-fold increases in anti-F IgG and PCA antibody titers in the unadjuvanted group. Development of our RSV F Vaccine for pediatrics would likely follow successful development of our RSV F Vaccine for maternal immunization.

Influenza

Burden of Disease

Influenza is a world-wide infectious disease that causes illness in humans ranging from mild to life-threatening symptoms or even death. Serious illness occurs not only in susceptible populations such as pediatrics and older adults, but also in the general population largely because of infection by unique strains of influenza for which most humans have not developed protective antibodies. Current estimates for seasonal influenza vaccine growth in the top seven markets (U.S., Japan, France, Germany, Italy, Spain and UK), show a potential increase from approximately $3.2 billion in the 2012-13 season to $5.3 billion by the 2021-22 season.23

The Advisory Committee for Immunization Practices of the Center for Disease Control and Prevention (“CDC”) recommends that all persons aged six months and older be vaccinated annually against seasonal influenza. Influenza is a major burden on public health worldwide: an estimated one million deaths each year are attributed to influenza.24 It is further estimated that, each year, influenza attacks between 5% and 10% of adults and 20% to 30% of children, causing significant levels of illness, hospitalization and death.25 One important advantage of recombinant seasonal influenza vaccines, like the candidate we are developing, is that once licensed for commercial sale, large quantities of such vaccine could potentially be manufactured quickly and in a cost-effective manner, without the use of either live influenza virus or eggs. Our recombinant influenza nanoparticles also can display conserved antigenic regions, which have the potential to elicit broadly neutralizing antibodies that appear to protect against a range of “drifted” strains, or influenza strains in which, over time, the hemagglutinin antigen undergoes an accumulation of genetic mutations at the hemagglutinin antigen sites that bind with neutralizing antibodies, potentially resulting in reduced protection of those antibodies. Additionally, nanoparticles offer improved purity and manufacturability and advantages for co-formulation with other nanoparticle-based vaccines.

Clinical Trial Update

In February 2018, we reported positive top-line results from our Phase 1/2 clinical trial of our nanoparticle seasonal influenza vaccine candidate, including our proprietary Matrix-M adjuvant (“NanoFlu™ vaccine”), in older adults that was initiated in September 2017. The trial was a randomized, observer-blinded, active comparator-controlled trial in approximately 330 healthy older adults. The primary objective of the trial wasWe continue to assess the safety and immunogenicity of two concentrations (15 micrograms or 60 micrograms) of NanoFlu vaccine compareddevelopment opportunities for our RSV Program for older adults.


Malaria

Malaria is a life-threatening disease caused by a parasite that infects mosquitos subsequently transmitted to humans. According to the leading licensed egg-based, high-dose influenza vaccine for older adults (“IIV3-HD”). Key findings from the trial include that Nanoflu vaccine induced:

Significantly higher hemagglutination inhibition (“HAI”) antibody responses against homologous H1N12021 WHO World Malaria Report, in 2020, there was an estimated 241 million malaria cases and H3N2 influenza viruses and comparable HAI responses against the homologous B/Brisbane strain;
Significantly higher HAI immune responses against historic and forward-drifted H3N2 virus strains; and
Strong neutralizing antibody responses that correlate with HAI results.

Overall, NanoFlu vaccine was well-tolerated over the three-week trial period. Given the strength of these trial results, we have submitted for publication627 thousand deaths worldwide in a peer-reviewed medical journal and/or for presentation at an upcoming scientific meeting. Based on these results, we expect to begin a Phase 2 trial of our NanoFlu vaccine in the third quarter of 2018.

Preclinical Analyses

Preclinical data in which NanoFlu was compared in a head-to-head challenge study against IIV3-HD, as well as IIV3-SD (standard dose) seasonal influenza vaccine, was announced in August 2017 and provided a strong rationale for the initiation of the Phase 1/2 trial. Our NanoFlu vaccine demonstrated significantly stronger and broader immune responses (microneutralizing antibodies) against homologous and heterologous influenza strains, including a series of drifted H3N2 strains evolved across over more than a decade of influenza seasons. In this preclinical challenge study, we showed that our NanoFlu vaccine was more protective than the licensed comparator vaccines against both a homologous H3N2 virus and a ten-year old drifted H3N2 strain. In parallel, we announced the achievement of significant improvements in manufacturing yields and product purity.

Emerging Viruses

Ebola Virus

EBOV, formerly known as Ebola hemorrhagic fever, is a severe, often fatal illness in humans. Multiple strains of EBOV have been identified, the most recent of which, the Makona EBOV strain, is associated with a case fatality rate of 50% to 90%.26 There are currently no licensed treatments proven to neutralize the virus, but a range of blood, immunological and drug therapies are under development. Despite the development of such therapies, current vaccine approaches target either a previous strain of the virus or were initially developed to be delivered by genetic vectors. In contrast, our EBOV glycoprotein vaccine candidate (“Ebola GP Vaccine”) was developed using the Makona EBOV strain.

In July 2015, we announced positive top-line data from our Phase 1 clinical trial of our Ebola GP Vaccine in ascending doses, with and without our Matrix-M adjuvant, in 230 healthy adults. Participants received either one or two intramuscular injections ranging from 6.5 micrograms to 50 micrograms of antigen, with or without adjuvant, or placebo. Immunogenicity was assessed at multiple time points, including days 28 and 35. These Phase 1 data demonstrated that our Ebola GP Vaccine is highly immunogenic, well-tolerated and, in conjunction with our proprietary Matrix-M adjuvant, resulted in significant antigen dose-sparing. The adjuvanted Ebola GP Vaccine was highly immunogenic at all dose levels; the adjuvanted two-dose regimens induced Ebola anti-GP antibody geometric mean responses between 45,000 and 70,000 ELISA units, representing a 500 to 750-fold rise over baseline at day 35. In 2015, we also announced successful data from two separate non-human primate challenge studies of our Ebola GP Vaccine in which, in both cases, the challenge was lethal for the control animal, whereas 100% of the immunized animals were protected.

Zika Virus

2020. We initiated development of a vaccine against the Zika virus (“ZIKV”) in response to the unmet global medical need for a response to this serious disease. The subsequent evolving epidemiology of ZIKV, which saw significant reductions in cases both in the U.S. and around the world in 2017, along with the uncertainty of governmental and non-governmental organization funding, has caused us to suspend these development efforts in lieu of competing resources and corporate priorities around more promising product development.

Combination Respiratory Vaccine

Given the ongoing development of our RSV F Vaccine and our desire to develop a combination respiratory vaccine with the potential to protect against both RSV and seasonal influenza, we made the decision to shift our seasonal influenza vaccine development focus from VLP-based seasonal influenza vaccines to nanoparticle-based seasonal influenza vaccines. We remain confident that a combination nanoparticle vaccine against both RSV and influenza is feasible.

CPLB Joint Venture (India)

CPL Biologicals Private Limited (“CPLB”), our joint venture company with Cadila Pharmaceuticals Limited (“Cadila”) in India, is actively developing a number of vaccine candidates that were genetically engineered by us. CPLB is owned 20% by us and 80% by Cadila. CPLB operates a manufacturing facility in India for the production of vaccines.

Seasonal Influenza

Since 2016, CPLB has been marketing CadiFlu-S, its trivalent VLP influenza vaccine in India, with limited sales in 2017 and expected in 2018.

Rabies

In October 2016, CPLB initiated its Phase 3 clinical trial in India of a recombinant rabies G protein vaccine candidate that can be administered in prophylactic regimens, both pre and post-exposure. The post-exposure regimen has the potential to use fewer doses (three doses) than the current standard of care (five doses). Data from the trial are expected in 2018.

Vaccine Technology

Our recombinant protein nanoparticle vaccine technology is based on self-assembly of surface protein antigens from pathogenic organisms including viruses, bacteria or parasites. The conformations of these nanoparticles are similar but not identical to the natural structure of surface antigens of disease organisms, and lack the genetic material required for replication and therefore are not infectious. Potential immunological advantages of protein nanoparticles may be associated with the nanoparticle conformation and the presentation of key functional epitopes that are often immunologically hidden in the native pathogen. This leads to efficient recognition by the immune system’s antigen presenting cells that trigger robust immune responses. Recognition of the nanoparticle vaccine’s repeating protein patterns by the antigen presenting cells’ toll-like receptors to stimulate innate immunity and the high purity and lack of synthetic material adds to the potential safety of recombinant nanoparticle vaccines. Protein nanoparticle vaccine technology has expanded our early-stage vaccines in development to include both virus and non-virus disease targets. Our most advanced protein nanoparticle vaccine candidate is our RSV F Vaccine, which self-assembles from our highly purified F-protein antigen.

Matrix Adjuvants

Adjuvants are predominantly used to enable a vaccine to increase the amplitude of the immune response and qualitatively change it, broaden its specificity to provide protection against related microorganisms and allow for effective immunization with much lower doses of antigen. Novavax AB has developed a number of adjuvant formulations, all based on our proprietary Matrix™ technology. These adjuvant formulations possess excellent immunostimulatory features with the ability to increase and prolong the protective benefits of vaccines.

While adjuvants based on novel, poorly characterized substances have been hampered by safety concerns and limited efficacy, Matrix adjuvants stimulate strong antibody and cell-mediated immune responses. Matrix adjuvants may allow for lower antigen doses, longer-duration immune responses and carry a lower risk for allergic reactions or other adverse events. Our Matrix technology typically induces strong cellular activation of both Th1 and Th2 types, thereby generating all classes and subclasses of antibodies, as well as potent cellular responses, including cytotoxic T lymphocytes. Our Matrix-M adjuvant provides a potent adjuvant effect that has been well-tolerated in clinical trials. We also believe that the strong immune response and opportunity to reduce the quantity of antigen dose can significantly reduce the production cost of our vaccines. This means that our Matrix-M adjuvantmalaria has the potential to be preventable through the R21 vaccine candidate, which is being developed through several partner-led trials and is formulated with our Matrix-MTM adjuvant.


R21 - Malaria Vaccine

R21 is a malaria vaccine candidate created by the Jenner Institute, University of Oxford, and formulated with our Matrix-M adjuvant. The University of Oxford has granted SIIPL a license for R21. We expect to manufacture and supply the Matrix-M adjuvant component of R21 to SIIPL. SIIPL has committed to manufacture at least 200 million doses per year of R21 after licensure, if granted. Additionally, SIIPL has rights to use Matrix-M adjuvant in R21 in regions where the disease is endemic and will pay royalties to us on its market sales of the vaccine. We will have commercial rights to sell and distribute the SIIPL-manufactured R21 in certain countries, primarily in the travelers’ and military vaccine markets.

R21 Clinical Development

R21 is currently being evaluated in a Phase 3 licensure trial initiated in May 2021. Data from this trial are expected in the second half of 2022. Previously, in April 2021, data from the Phase 2b trial evaluating R21 was published in The Lancet, demonstrating 77% efficacy when formulated with 50 micrograms of Matrix-MTM adjuvant and 71% efficacy when formulated with 25 micrograms of Matrix-MTM adjuvant. Both adjuvant dose levels were well tolerated in young children, with no severe reactions to R21 reported.

Advance Purchase Agreements (“APA”)

We have entered into APAs (also referred to as “supply agreements” throughout this Annual Report on Form 10-K) with Gavi, the Vaccine Alliance (“Gavi”), the EC, and various countries globally. The APAs typically contain terms that include upfront payments intended to assist us in funding investments related to building out and operating our manufacturing and distribution network, among other expenses, in support of our global supply commitment. Such upfront payments generally become non-refundable upon our achievement of certain development milestones. We expect to sign additional APAs that are currently in active discussions and negotiations.

15

A summary of our APAs follows:

nvax-20211231_g5.jpg

(1) The APA includes an option to order additional doses as may be required from time to time.

Under the terms of our APA with Gavi, 1.1 billion doses of NVX-CoV2373 are to be made available to countries participating in the COVAX Facility, which was established to allocate and distribute vaccines equitably to participating countries and economies. We expect to manufacture and distribute 350 million doses of NVX-CoV2373 to countries participating under the COVAX Facility. Under a separate purchase agreement with Gavi, SIIPL is expected to manufacture and deliver the balance of the 1.1 billion doses of NVX-CoV2373 for low- and middle-income countries participating in the COVAX Facility. We expect to deliver doses with antigen and Matrix-MTM adjuvant manufactured at facilities directly funded by the investments previously received from CEPI (the “CEPI Funding Agreement”). We expect to supply significant valuedoses that Gavi would allocate to low-, middle-, and high-income countries, subject to certain limitations, utilizing a tiered pricing schedule and Gavi may prioritize such doses to low- and middle-income countries at lower prices. Additionally, we may provide additional doses of NVX-CoV2373, to the extent available from CEPI-funded manufacturing facilities, in the event that SIIPL cannot materially deliver expected vaccine doses to the COVAX Facility. Together with SIIPL, we expect to initiate delivery of doses following receipt of appropriate regulatory authorizations. Under the agreement, we received an upfront payment from Gavi of $350 million in 2021 and recorded a receivable as of December 31, 2021, for an additional payment of $350 million because we secured EUL for NVX-CoV2373 from the WHO in December 2021.

Under the terms of our APA with the EC, acting on behalf of various E.U. member states, we are committed to supply a minimum of 20 million and up to 100 million initial doses of NVX-CoV2373, with the option for the EC to purchase an additional 100 million doses through 2023. We have received orders for 69 million doses under this agreement.

License and Collaboration
Our commitment to partnering globally in efforts to end the COVID-19 pandemic is demonstrated through our partnership with SIIPL to supply NVX-CoV2373 to India and low- and middle-income countries. In August 2020, we expanded upon our manufacturing and supply capabilities to include partnerships with both Takeda in Japan and SK bioscience in South Korea and furthered these collaborations in February and December 2021. These additional partnerships will increase our production capacity and are expected to support a rapid roll-out of NVX-CoV2373 globally.

A summary of our license and collaboration agreements follows:

SIIPL

In July 2020, we entered into a supply and license agreement with SIIPL, which was amended in September 2020 and amended and restated in July 2021, under which we granted exclusive and non-exclusive licenses to SIIPL for the development, co-formulation, filling and finishing, registration, and commercialization of NVX-CoV2373. SIIPL agreed to purchase our Matrix-MTM adjuvant and we granted SIIPL a non-exclusive license to manufacture the antigen drug substance component of NVX-CoV2373 in SIIPL’s licensed territory solely for use in the manufacture of NVX-CoV2373. We will equally split the revenue from SIIPL's sale of NVX-CoV2373 in its licensed territory, net of agreed costs. We granted to SIIPL (i) an exclusive license in India during the agreement, and (ii) a non-exclusive license (a) during the “Pandemic Period” (as declared by the World Health Organization), in all countries other than specified countries designated by the World Bank as upper-middle or high-income countries, with respect to which we retains rights, and (b) after the Pandemic Period, in only those countries designated as low or middle-income by the World Bank. Following the Pandemic Period, we may notify SIIPL of any bona fide opportunities for us to license NVX-CoV2373 to a third party in such low and middle-income countries and SIIPL would have an opportunity to match or improve such third-party terms, failing which, we would have the discretion to remove one or more non-exclusive countries from SIIPL’s license. In October 2021, we entered into a supply agreement and a contract development manufacturing agreement with SIIPL and Serum Life Sciences Limited (“SLS”) under which SIIPL and SLS will supply us with NVX-CoV2373 for commercialization and sale in certain territories.

Takeda

In February 2021, we finalized a collaboration and license agreement with Takeda under which we granted Takeda an exclusive license to develop, manufacture and commercialize NVX-CoV2373 in Japan. Under the agreement, Takeda purchases Matrix-M™ adjuvant from us to manufacture doses of finished NVX-CoV2373 and we are entitled to receive payments from Takeda based on the achievement of certain development and commercial milestones, as well as a portion of net profits from the sale of NVX-CoV2373. In September 2021, Takeda finalized an agreement with MHLW for the purchase of 150 million doses of NVX-CoV2373. The announcement followed an update from MHLW on its ongoing efforts to secure coronavirus vaccine for the citizens of Japan. These efforts include vaccine procurement by Takeda pursuant to the terms of the collaboration and license agreement we entered into with Takeda in February 2021. Distribution of our vaccine in Japan by Takeda is expected to begin in 2022, pending regulatory approval. Takeda anticipates the capacity to manufacture 150 million doses of NVX-CoV2373 per year.

SK bioscience

In February 2021, we finalized an expanded collaboration and license agreement with SK bioscience to manufacture and commercialize NVX-CoV2373 for sale to the government of Korea. Concurrently, SK bioscience finalized an advance purchase agreement with the Korean government to supply 40 million doses of NVX-CoV2373 to the Republic of Korea beginning in 2021. Our agreement is in addition to our existing manufacturing arrangement with SK bioscience entered into in August 2020. Under the collaboration agreement, SK bioscience was granted an exclusive license to develop, manufacture, and commercialize NVX-CoV2373 in the Republic of Korea. SK bioscience will pay a tiered royalty in the low to middle double-digit range on the sale of NVX-CoV2373 in the Republic of Korea. In May 2021, we entered a non-binding
17

Memorandum of Understanding (“MOU”) with the Ministry of Health and Welfare of Korea and SK bioscience to explore further cooperation in the development and manufacturing of vaccines, including NVX-CoV2373 and to potentially explore the development of new vaccine products with SK bioscience, including COVID-19 variant vaccines and/or an influenza/COVID-19 combination vaccine. In December 2021, we amended the collaboration and license agreement to grant a non-exclusive license to cover Thailand and Vietnam, subject to a low to middle double-digit royalty, and for SK biosciences to supply the antigen component of NVX-CoV2373 to us for use in the final drug product globally, including product distributed by the COVAX Facility.

Manufacturing and Supply
We are committed to discovering, developing, and commercializing innovative vaccines to prevent serious infectious diseases and are exploring a number of combination vaccine candidates, including a COVID-influenza combination vaccine directly and by leveraging our strategic global partnerships. In 2021 and 2020, we established a global supply chain to support the commercialization of NVX-CoV2373. The acquisition of Novavax CZ (formerly Praha Vaccines, a.s.) in the Czech Republic in May 2020 demonstrated the Company’s first major step toward building out our global manufacturing capabilities. Since May 2020, we have established partnerships worldwide to amplify and solidify our global reach.

To date, we have increased our projected global manufacturing production rate of NVX-CoV2373 to be over two billion annualized doses when therewe are at full capacity. Of this anticipated capacity, approximately one billion doses will be manufactured by SIIPL.

A summary of our key manufacturing and supply arrangements follows:
Matrix-MTM Adjuvant
We manufacture our proprietary saponin-based Matrix-M™ adjuvant at our Novavax AB facility in Uppsala, Sweden.
In June 2020, we entered into contract manufacturing arrangements with AGC Biologics and the Polypeptide Group to provide contract development and manufacturing services, supplying us with large-scale production of Matrix-M™ adjuvant.
Antigen Component of NVX-CoV2373
In October 2021, we entered into a supply agreement with SIIPL and SLS, an affiliate of SIIPL, for the manufacture of NVX-CoV2373. In October 2021, we also entered into a contract development manufacture agreement with SLS, where SLS will manufacture and supply finished vaccine product to us using antigen drug substance and Matrix-M™ adjuvant supplied by us.
In October 2021, we entered into a contract manufacturing agreement with Mabion S.A. (“Mabion”) for the large-scale manufacturing of NVX-CoV2373 through 2026. This agreement follows the successful completion of technology transfer to Mabion for antigen production of NVX-CoV2373. We are scaling up manufacturing of NVX-CoV2373 at Mabion’s Good Manufacturing Practice-certified facility located near Warsaw, Poland.
In August 2021, we extended our partnership with FUJIFILM Diosynth Biotechnologies through an agreement for long-term commercial manufacturing of NVX-CoV2373 through 2025. Under this agreement, FUJIFILM Diosynth Biotechnologies has continued to manufacture the antigen component of NVX-CoV2373 at its sites in Morrisville, North Carolina, College Station, Texas, and Billingham, UK. This development follows a previous manufacturing agreement with FUJIFILM Diosynth Biotechnologies, which we entered into in July 2020.
In June 2021, we announced the completion of construction of the National Research Council of Canada’s Biologics Manufacturing Centre and ongoing technology transfer for the production of NVX-CoV2373. Technology transfer to establish a step-by-step process of producing NVX-CoV2373 at the Biologics Manufacturing Centre began in April 2021 following a collaboration agreement entered into with the National Research Council of Canada in March 2021. These developments build upon a MOU entered into in February 2021 with the Canadian government to produce NVX-CoV2373 at

Competition in RSV, EBOV,COVID-19, Influenza, and Other Vaccines

RSV


The vaccine market is intensely competitive, characterized by rapid technological progress. Our technology is based upon utilizing the baculovirus expression system in insect cells to make recombinant vaccines. Our 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. We believe this baculovirus expression system offers many advantages when compared to other technologies and is uniquely well-suited for developing RSVCOVID-19, influenza, and influenzaRSV vaccines, as well as vaccines against a number of other infectious diseases.

There is currently no approved RSV vaccine for sale in the world; however, a

A number of vaccine manufacturers, academicresearch institutions, and other organizations currently have, or have had, programs to develop such a vaccine. In addition, many other companies are developing products to prevent disease caused by RSV using a vaccine for SARS-CoV-2, the virus that causes COVID-19 disease. A variety of technology platforms,different vaccine technologies are being studied, including variousnucleic acid (RNA/DNA), viral vector technologies, monoclonal antibodies (Mab)vectors, live attenuated or inactivated, and protein-based vaccines. According to a coronavirus vaccine tracker published by The New York Times, and competitive recombinant technologies. We believe that our RSV vaccine candidate, utilizing a recombinant F-protein antigen, is more effective than RSV vaccine candidatesupdated as of February 23, 2022, there are 115 vaccines in development by our competitors; however, such efficaciousness cannot be guaranteed. Although we are not aware of all our competitors’ efforts, we believe that MedImmune, LLC (“MedImmune”), a subsidiary of AstraZeneca PLC, may have the second most advanced RSV vaccine program after Novavax, as it has reported testing in Phase 1 and Phase 1/2 clinical trials and 49 have reached the final stages of an intranasal, recombinant, live attenuated, RSVtesting. As of January 2022, Novavax is one of five manufacturers that have a COVID-19 vaccine that has received Conditional Marketing Authorization by the EMA in the European Union, with the other manufacturers being Pfizer, Moderna, Johnson & Johnson and AstraZeneca. As of January 2022, Pfizer has received BLA approval and Moderna and Johnson & Johnson have each received EUA by the FDA in the U.S for their COVID-19 vaccines. As of January 2022, we submitted for EUA by the prevention of lower respiratory tract disease caused by RSV, as well as a combination intranasalFDA for NVX-CoV2373, marking the first protein-based COVID-19 vaccine forfiling. Based on NVX-CoV2373’s high efficacy against both the prevention of several infant respiratory illnesses, including RSV. In older adults, MedImmune also conducted a Phase 2 trial of MEDI-7510 (recombinant F subunit with an adjuvant administered intramuscularly). In both MedImmune vaccine programs, the trials did not report complete success. Another approach by MedImmune (partnered with Sanofi) is passive immunity as provided by MEDI-8897 (an RSV monoclonal antibody)original and is currently in Phase 2 trials for preterm infants. A similar Mab from Regeneron (REGN-2222) failed a Phase 3 trial in preterm infants,variant strains and its development has since been discontinued. Additional entities have also entered into earlywell-tolerated profile demonstrated in clinical trials, including GlaxoSmithKline, Sanofi, Bavarian Nordic, J&J/Crucell, Ablynx, Immunovaccine, Mucosis, Vaxarttwo pivotal Phase 3 trials in the U.K. and the National Institute of Allergy and Infectious Diseases,U.S., we believe our vaccine candidate will play an institute under the U.S. National Institutes of Health (“NIAID”).

There are aimportant role in addressing this global public health crisis.


A number of companies are developing and selling vaccines for seasonal influenza employing both traditional (egg-based) and new vaccine technologies (cell-based). Many seasonal influenza vaccines are currently approved and marketed, and most of these are marketed by major pharmaceutical companies that have significantly greater financialsuch as Sanofi Pasteur, GSK and technical resources, experience and expertise.Seqirus. Competition in the sale of seasonal influenza vaccines is intense. For the older adult segment, Sanofi currently supplies Fluzone-HD® and Flublok® to the majority of older adults in the U.S. Therefore, newly developed and approved products must be differentiated from existing vaccines in order to have commercial success. In order to show differentiation in the seasonal influenza market, a product may need to be more efficacious and/or be less expensive and quicker to manufacture.manufacture, all while still showing a comparable or improved tolerability profile. Many of our competitors are working on new products and new generations of current products, some by adding an adjuvant that is used to increase the immunogenicity of that product, each of which is intended to be more efficacious than currently marketed products. Another differentiating factor is recombinant manufacturing, which we believe can be quicker and less-expensiveSeveral competitors are working on developing seasonal influenza vaccines using different technologies than traditional egg-based manufacturing.those in existing marketed vaccines, the most notable being mRNA. Despite the significant competition and advancing technologies, some of which are similar tobased on our own,completed Phase 3 trial results, we believe that NanoFlu Program, our adjuvanted nanoparticle seasonal influenza product NanoFlu™ vaccine, could be as efficacious as, or more so than, current products or products being developed by our competitors,competitors.

There is currently no approved RSV vaccine for sale in the world; however, a number of vaccine manufacturers, academic institutions and other organizations currently have, or have had, programs to develop such a vaccine. These groups are developing products to prevent disease caused by RSV using a variety of technology platforms, including viral vectors, nucleic acid (RNA/DNA), live attenuated chimeric, antigens or monoclonal antibodies (“Mab”) and competitive recombinant technologies. We continue to believe that our manufacturing system provides savings in both time and money; however, there can be no guarantee that our seasonal influenza vaccine will proveRSV F Vaccine candidate, which is a recombinant prefusogenic F-protein nanoparticle, is likely to be efficaciousas effective as other RSV vaccine candidates or that our manufacturing system will prove to be sufficiently effective and differentiated to ensure commercial success.

Vaccine candidates against EBOV have beenother products in development for more thanby our competitors. At this time, there are a decade; however,number of companies and other organizations with the recent epidemic in West Africa (now subsided), focus on viable vaccine candidates has intensified. The WHO has reported two vaccine candidates thatin late-stage clinical trials. In older adults, GSK, Pfizer, and Janssen are currently being tested in humans: one by GlaxoSmithKlinePhase 3 trials. GSK and Pfizer both are in collaboration with NIAID,Phase 3 trials for infants via maternal immunization. Additionally, both the AstraZeneca / Sanofi partnered monoclonal antibody and the other by a collaboration of NewLink Genetics, Merck Vaccines USA (“Merck”) and the Public Health Agency of Canada. The Merck vaccine is the only one to have completed some humanmonoclonal antibody are in Phase 3 trials before the epidemic faded, to have had data published, and to now be planning to file for licensure. While these and other vaccine candidates offer promise, we believe there are accompanying challenges, including: high-dose level requirements; utilization of glycoprotein from older strains that have a significant number of amino acid changes when compared to the 2014 Makona strain; difficult storage requirements at temperatures below –60°C; and challenges associated with immunity to the viral vectors, which could limit their multi-dose vaccine potential. In contrast, we have developed a Phase 1 vaccine candidate that has performed well with low doses utilizing our Matrix-M adjuvant, was derived from the 2014 Makona strain, appears to be stable at 2–8°C and appears to provide enhanced immunogenicity as a multi-dose vaccine.

in infants.


In general, competition among pharmaceutical products is based in part on product efficacy, safety, reliability, availability, price and patent position. An important factor is the relative timing of the market introduction of our products and our competitors’ products. Accordingly, the speed with which we can develop products, complete the clinical trials and
19

approval processes and supply commercial quantities of the products to the market is an important competitive factor. Our competitive position also may depend upon our ability to show differentiation with a product that is more efficacious and/or less expensive and quicker to manufacture. Other factors affecting our competitive position include our ability to attract and retain qualified personnel, obtain patent protection or otherwise develop proprietary products or processes and secure sufficient capital resources for the lengthy period between technological conception and commercial sale.

Patents and Proprietary Rights

We generally seek patent protection for our technology and product candidates in the U.S. and abroad. The patent position of biotechnology and pharmaceutical firms generally is highly uncertain and involves complex legal and factual questions. Our success will depend, in part, on whether we can:

·obtain patents to protect our own technologies and product candidates;
·obtain licenses to use the technologies of third-parties, which may be protected by patents;
·protect our trade secrets and know-how; and
·operate without infringing the intellectual property and proprietary rights of others.

Trade Secrets.

Secrets

We also rely significantly on trade secret protection and confidentiality agreements to protect our interests. It is our policy to require employees, consultants, contractors, manufacturers, collaborators and other advisors to execute confidentiality agreements upon the commencement of employment, consulting or collaborative relationships with us. We also require confidentiality agreements from any entity that is to receive confidential information from us. With respect to employees, consultants and contractors, the agreements generally provide that all inventions made by the individual while rendering services to us shall be assigned to us as our property.

Government Regulations

The development, production and marketing of biological products, which include the vaccine candidates being developed by Novavax or our collaborators, are subject to regulation for safety, efficacy and quality by numerous governmental authorities in the U.S. and other countries. As a U.S. based company,Although we focus on the U.S. regulatory process and the standards imposed by the FDA, the International Conference on Harmonisation (“ICH”) and other agencies because we believe for the most part, meeting U.S. and ICH standards will allowgenerally allows us to satisfy regulatory agencies in other countries where we intend to do business. Webusiness; however, we are awaremindful that expectations in some venues, notably in the European Union and the United Kingdom (in relation to Great Britain), differ to some degree and we are takingtake proactive steps to address such differences.differences by maintaining regular filings and correspondence and attending regular meetings with many other non-U.S. regulatory agencies. In the U.S., the development, manufacturing and marketing of human pharmaceuticals and vaccines are subject to extensive regulation under the Federal Food, Drug, and Cosmetic Act, and biological products are subject to regulation under provisions of that act and the Public Health Service Act. The FDA not only assesses the safety and efficacy of these products but it also regulates, among other things, the testing, manufacture, labeling, storage, record-keeping, advertising and promotion of such products. The process of obtaining FDA licensure for a new vaccine is costly and time-consuming.

Vaccine clinical development in most countries follows the same general regulatory pathway as drugs and other biologics. Before applying for FDA licensure to market any new vaccine candidate, we expect to first submit an investigational new drug application (“IND”) that explains to the FDA, among other things, the results of preclinical toxicology testing conducted in laboratory animals, the method of manufacture, quality control tests for release, the stability of the investigational product and what we propose to do for human testing. At this stage, the FDA decides whether it is reasonably safe to move forward with testing the vaccine candidate in humans. We must then conduct Phase 1 clinical trials and larger-scale Phase 2 and 3 clinical trials that demonstrate the safety, immunogenicity and efficacy of our vaccine candidate to the satisfaction of the FDA. Once these trials are complete,Following successful completion of all three phases of clinical development, a Biologics License Application (“BLA”)BLA can be submitted to the FDA requesting licensure of the vaccine for marketing based on the vaccine’s safety and efficacy.

Similar pathways exist in Europe and other geographies.

The FDA will only approve a BLA if the vaccine is demonstrated to be safe, pure and potent. During the FDA’s review of a BLA, the proposed manufacturing facility undergoes a pre-approval inspection during which the FDA examines in detail the production of the vaccine, the manufacturing facility and the quality documentation related to the vaccine. Vaccine licensure also requires the provision of adequate product labeling to allow health care providers to understand the vaccine’s proper use, including its potential benefits and risks, to communicate with patients and parents, and to safely deliver the vaccine to the public. Until a vaccine is given to the general population, all potential adverse events cannot be anticipated. Thus, the FDA typically requires Phase 4 post-marketing clinical trials for vaccines after licensure to continue gathering safety, and sometimes effectiveness/efficacy data in the indicated and additional populations.

The Commissioner of the FDA may, under delegated authority from the Secretary of the DHHS, and under certain circumstances, issue an EUA, that would permit the use of an unapproved medical product or unapproved use of an approved medical product to diagnose, treat, or prevent serious or life-threatening diseases or conditions when there are no adequate, approved, and available alternatives. When issuing an EUA, the FDA imposes conditions of authorization, with which the EUA holder must comply. Such conditions include, but may not be limited to, compliance with labeling, distribution of materials designed to ensure proper use, reporting obligations, and restrictions on advertising and promotion. The EUA is only effective for the duration of the public health emergency. The FDA may also revise or revoke the EUA sooner if, the criteria for issuance are no longer met or other circumstances make a revision or revocation appropriate to protect the public health or safety. For example, an EUA may be revoked when the FDA determines that the underlying public health emergency no longer exists or warrants such authorization, or for reasons such as significant adverse inspectional findings, reports of adverse events linked to or suspected of being caused by the EUA product, or newly emerging data that may demonstrate the product may not be effective.
In order to ensure continuing safety, the FDA continuesand most other non-U.S. based regulatory agencies continue to oversee the production of vaccines even after the vaccine and manufacturing processes are approved. For example, monitoring of the vaccine and of production activities, including periodic facility inspections, must continue as long as the manufacturer holds a license for the product. Manufacturers may also be required to submit to the FDA the results of their own tests for

potency, safety and purity for each vaccine lot, if requested by the FDA.relevant regulatory agency. They may also be required to submit samples of each vaccine lot to the FDAagency for testing.

11

In addition to obtaining FDA licensure for each product, each domestic manufacturing establishment must be registered with the FDA, is subject to FDA inspection and must comply with cGMPcurrent Good Manufacturing Practices (“GMP”) regulations. To supply products for use either in the U.S. or outside the U.S., including clinical trials, U.S. and foreign manufacturing establishments, including third-party facilities, must comply with GMP regulations and are subject to periodic inspection by the FDA or by corresponding regulatory agencies in their home country.

In 1992,

The EU and the U.K. similarly provide a faster means to achieve approval by offering conditional marketing authorizations which are granted with the proviso of obtaining additional data to eventually become unconditional, but which allow authorization to be granted earlier albeit with a more limited set of clinical data.
The FDA instituted regulations that allow acceleratedhas several programs designed to expedite the development and approval of certaindrugs and biological products thatintended to treat serious or life-threatening illnessesdiseases or conditions, including fast track designation, breakthrough therapy designation, priority review designation, and provide meaningful therapeutic benefitaccelerated approval. First, the FDA may designate a product for Fast Track review if it is intended, whether alone or in combination with one or more other products, for the treatment of a serious or life-threatening disease or condition and demonstrates the potential to address unmet medical needs for such a disease or condition. For Fast Track products, sponsors may have more frequent interactions with the FDA and the FDA may initiate review of sections of a Fast Track product’s application before the application is complete. The FDA granted Fast Track Designation for NVX-CoV2373 in November 2020 and for NanoFlu, our recombinant quadrivalent seasonal influenza vaccine candidate, in January 2020.
Second, a product may be designated as a Breakthrough Therapy if it is intended, either alone or in combination with one or more other products, to treat a serious or life-threatening disease or condition and preliminary clinical evidence indicates that the product may demonstrate substantial improvement over existing treatments basedtherapies on one or more clinically significant endpoints. The FDA may hold meetings with the sponsor throughout the development process; provide timely advice to the product sponsor regarding development and approval; involve more senior staff in the review process; assign a cross-disciplinary project lead for the review team; and take other steps to design the clinical trials in an efficient manner.

Third, the FDA may designate a product for priority review if it is a product that treats a serious disease or life-threatening condition and, if approved, would provide a significant improvement in safety or effectiveness over available therapies. Significant improvement may be illustrated by evidence of increased effectiveness in the treatment of a condition, elimination or substantial reduction of a treatment-limiting product reaction, documented enhancement of patient compliance that may lead to improvement in serious outcomes, and evidence of safety and effectiveness in a new subpopulation. A priority designation is intended to direct overall attention and resources to the evaluation of such applications, and, for a drug product (including a vaccine), to shorten the FDA’s goal for taking action on a marketing application from ten months to six months.

Fourth, a product may be eligible for accelerated approval, if it treats a serious or life-threatening condition and generally provides a meaningful advantage over available therapies. In addition, it must demonstrate an effect on a surrogate endpoint versusthat is reasonably likely to predict clinical benefit or on a clinical outcome, whichendpoint that can take many more yearsbe measured earlier than irreversible morbidity or mortality, or IMM that is reasonably likely to demonstrate. Surrogate endpoints, generally a laboratory measurementpredict an effect on IMM or other physical sign shown to have some correlation with clinical benefit, can considerably shortenbenefit. As a condition of approval, the development time leading up to FDA licensure. The FDA bases its decision on whether to acceptmay require that a proposed surrogate endpoint on the scientific support for that endpoint. The company developing the product is required to conduct further studiessponsor of a drug or biologic receiving accelerated approval perform adequate and well-controlled post-marketing clinical trials to confirm efficacy using a clinically meaningful endpoint, thereby confirming efficacy observed pre-approval using a surrogate endpoint. In June 2019, we announced that the clinical benefit in Phase 4 confirmatory efficacy trials. We plan to seekFDA acknowledged that the accelerated approval pathway is available for our seasonal influenza vaccine for older adults, but have not ruled out the potential use of traditional approval.

In addition to regulatory approvals that must be obtained in the U.S., an investigational product is also subject to regulatory approval in other countries in which it is intended to be marketed. No such product can be marketed in a country until the regulatory authorities of that country have approved an appropriate marketing application. FDA licensure does not assureguarantee approval by other regulatory authorities. In addition, in many countries, the government is involved in the pricing of the product. In such cases, the pricing review period often begins after market approval is granted.

We are also subject to regulation under the Occupational Safety and Health Act, the Environmental Protection Act, the Toxic Substances Control Act, the Resource Conservation and Recovery Act and other present and potential federal, state or local regulations, including national and local regulations that govern our facility in Sweden. These and other laws govern our use, handling and disposal of various biological and chemical substances used in, and waste generated by our operations. Our research and development involves the controlled use of hazardous materials, chemicals and viruses. Although we believe that our safety procedures for handling and disposing of such materials comply with the standards prescribed by state and federal regulations, the risk of accidental contamination or injury from these materials cannot be completely eliminated.
22

In the event of such an accident, we could be held liable for any damages that result and any such liability could exceed our resources. Additionally, for formulations containing controlled substances, we are subject to Drug Enforcement Act regulations.


In both domestic and foreign markets, sales of any products for which we receive regulatory approval for commercial sale will depend in part on the availability of reimbursement from third-party payors.payers. Third-party payorspayers include government authorities or programs, private health insurers (including managed care plans) and other organizations. These third-party payorspayers are increasingly challenging the price and examining the cost-effectiveness of medical products and services. In addition, significant uncertainty exists as to the reimbursement status of newly approved healthcare products. We may need to conduct expensive pharmacoeconomic studies in order to demonstrate the cost-effectiveness of our products. There may be significant delays in obtaining coverage and reimbursement for newly approved drugs, and coverage may be more limited than the indications for which the product is approved by the FDA or similar regulatory authorities outside the United States. Our product candidates may not be considered cost-effective.cost-effective at certain prices. Adequate third-party reimbursement may not be available in certain markets to enable us to maintain price levels sufficient to realize an appropriate return on our investment in product development. Third-party payors may also control access to, or manage utilization of, our products with various utilization management techniques.

Decreases in third-party reimbursement for our product candidates or a decision by a third-party payer to not cover our product candidates could reduce physician utilization of our products and have a material adverse effect on our sales, results of operations and financial condition.

Within the U.S., if we obtain appropriate approval in the future to market any of our product candidates, those products could potentially be covered by various government health benefit programs as well as purchased by government agencies. The participation in such programs or the sale of products to such agencies is subject to regulation. In exchange for coverage, we may be obligated to provide rebates or offer discounts under government health programs or to government and private purchasers.


The U.S. and state governments continue to propose and pass legislation designed to reform delivery of, or payment for, health care, which includeincluding initiatives to reduce the cost of healthcare. For example, in March 2010, the U.S. Congress enacted the Patient Protection and Affordable Care Act and the Health Care and Education Reconciliation Act (“Healthcare Reform Act”) which includes changes to the coverage and reimbursement of drug products under government health care programs. Under the Trump administration, there have been ongoingwere several efforts to modify or repeal all or certain provisions of the Healthcare Reform Act, and some modifications were implemented. Adoption of price controls and cost-containment measures and adoption of more restrictive policies in jurisdictions with existing controls and measures could further limit our net revenue and results.

Other legislative changes have been implemented. proposed and adopted in the United States since the Healthcare Reform Act was enacted. For example, through the process created by the Budget Control Act of 2011, there are automatic reductions of Medicare payments to providers of up to 2% per fiscal year, which went into effect in April 2013 and will remain in effect through 2030 due to subsequent legislative amendments contained in the Coronavirus Aid, Relief, and Economic Security Act, commonly referred to as the “CARES Act”. In November 2020, the Centers for Medicare and Medicaid Services (“CMS”) issued an interim final rule that seeks to lower prescription drug costs by paying no more for certain Medicare Part B drugs than the lowest price paid for such drugs in certain other countries (the "Most Favored Nation Rule”). Under the rule, the lower payment rates for affected drugs would be phased in over a period of four years, beginning in 2021. The rule has been challenged by industry associations on a number of grounds. On December 28, 2020, the U.S. District Court for the Northern District of California issued a nationwide preliminary injunction in Biotechnology Innovation Organization v. Azar, No. 3:20-cv-08603, which preliminarily enjoins CMS from implementing the Most Favored Nation Rule. Given this preliminary injunction, the Most Favored Nation Rule was not implemented on January 1, 2021 and will not be implemented without further rule-making. However, this interim final rule or any similar type of reference pricing regulation could potentially harm our business if expanded to include our products.

Recently, there has been considerable public and government scrutiny in the U.S. of pharmaceutical pricing and proposals to address the perceived high cost of pharmaceuticals. There have also been several recent state legislative efforts to address drug costs, which generally have focused on increasing transparency around drug costs or limiting drug prices or price increases. Adoption of new legislation at the federal or state level could affect demand for, or pricing of, our product candidates if approved for sale. It is also possible that additional governmental action will be taken in response to the COVID-19 pandemic. We cannot predict the ultimate content, timing or effect of any federal and state reform efforts. There is no assurance that federal or state health care reform will not adversely affect our future business and financial results.

12


Similarly, in many countries outside the U.S., pharmaceutical pricing is subject to regulatory control, particularly in countries where healthcare is provided mainly through government funding or government backed insurers. In such countries governmental organizations will generally determine firstly if a medicinal product might be reimbursed and secondly the maximum price payable.
23


Within the U.S., we may be subject to various federal and state laws pertaining to health care “fraud and abuse,” including anti-kickback laws and false claims laws, for activities related to future sales of any of our product candidates that may in the future receive regulatory and marketing approval. Anti-kickback laws generally prohibit a pharmaceutical manufacturer from soliciting, offering, receiving or paying any remuneration to generate business, including the purchase, prescription or use of a particular drug. Although the specific provisions of these laws vary, their scope is generally broad and there may not be regulations, guidance or court decisions that apply the laws to particular industry practices. There is therefore a possibility that our practices might be challenged under such anti-kickback laws. False claims laws, including the federal False Claims Act (“FCA”), prohibit anyone from knowingly and willingly presenting, or causing to be presented, any claims for payment for reimbursed drugs or services to third party payorspayers (including Medicare and Medicaid) that are false or fraudulent.

Our activities relating to the sale and marketing of our products may be subject to scrutiny under these laws. Violations of fraud and abuse laws may be punishable by criminal or civil sanctions, including fines and civil monetary penalties, and exclusion from federal health care programs (including Medicare and Medicaid). In the U.S., federal and state authorities are paying increased attention to enforcement of these laws within the pharmaceutical industry and private individuals have been active in alleging violations of the laws and bringing suits on behalf of the government under the FCA. If we were subject to allegations concerning, or were convicted of violating, these laws, our business could be harmed.


On November 20, 2020, the DHHS published a Final Rule entitled “Removal of Safe Harbor Protection for Rebates to Plans or PBMs Involving Prescription Pharmaceuticals and Creation of New Safe Harbor Protection,” commonly referred to as the “Rebate Rule”, which amends the federal Anti-Kickback Statute discount safe harbor by eliminating protection for price concessions, including rebates, that are offered by pharmaceutical manufacturers to plan sponsors, or pharmacy benefit managers under contract with them, under the Medicare Part D program and Medicare Advantage Plans, unless the price reduction is one required by law. Effective January 1, 2022, in advance of the calendar year 2022 Part D plan year, safe harbor protection will be eliminated for manufacturer rebates paid directly (or indirectly through a pharmacy benefit manager) to Part D prescription drug plans and Medicare Advantage prescription drug plans. Effective December 30, 2020, the Rebate Rule established two new safe harbors. The first new safe harbor protects price reductions paid by manufacturers to prescription drug plans (including prescription drug plans offered by Medicare Advantage organizations) and Medicaid managed care organizations, which are fully reflected at the point-of-sale. The second new safe harbor protects fair-market-value service fees paid to pharmacy benefit managers by manufacturers. This new rule could result in a change in incentives for health plans and pharmacy benefit managers in negotiating rebates and discounts with manufactures for preferred formulary placement. At this time we cannot predict how these changes will impact our business and operations once our product candidates are commercialized.

Within the European Union and the United Kingdom, the provision of benefits or advantages to physicians to induce or encourage the prescription, recommendation, endorsement, purchase, supply, order or use of medicinal products is prohibited. The provision of benefits or advantages to physicians is also governed by the national anti-bribery laws of EU Member States and the United Kingdom, such as the U.K. Bribery Act 2010. Infringement of these laws could result in substantial fines and imprisonment.

We are also subject to the U.S. Foreign Corrupt Practices Act (“FCPA”), which prohibits any U.S. individual or business from paying, offering, authorizing payment or offering anything of value, directly or indirectly, to any foreign official, political party or candidate for the purpose of influencing any act or decision of the foreign entity in order to assist the individual or business in obtaining or retaining business. The FCPA also obligates companies whose securities are listed in the U.S. to comply with certain accounting provisions requiring the company to maintain books and records that accurately and fairly reflect all transactions of the corporation, including international subsidiaries, and to devise and maintain an adequate system of internal accounting controls for international operations. Compliance with the FCPA is expensive and difficult, particularly in countries in which corruption is a recognized problem. In addition, the FCPA presents particular challenges in the pharmaceutical industry, because, in many countries, hospitals are operated by the government, and doctors and other hospital employees are considered foreign officials. Certain payments to hospitals in connection with clinical trials and other work have been deemed to be improper payments to government officials and have led to FCPA enforcement actions. Various laws, regulations and executive orders also restrict the use and dissemination outside the U.S. or the sharing with certain non-U.S. nationals, of information classified for national security purposes, as well as certain products and technical data relating to those products. As we expand our presence outside the U.S., it will require us to dedicate additional resources to comply with these laws, and these laws may preclude us from developing, manufacturing, or selling certain products and product candidates outside the United States, which could limit our growth potential and increase our development costs. We cannot guarantee that we, our employees, our consultants, or our third-party contractors are or will be in compliance with all federal, state, and foreign regulations regarding bribery and corruption. Moreover, our strategic collaborators and third-party contractors located outside the U.S. may have inadequate compliance programs or may fail to respect the laws and guidance of the territories in which they operate. The failure to comply with laws governing international business practices may result in substantial civil and criminal penalties and suspension or debarment from government contracting. The Securities and Exchange Commission (“SEC”) also may suspend or bar issuers from trading securities on
24

U.S. exchanges for violations of the FCPA’s accounting provisions. Even if we are not determined to have violated these laws, government investigations into these issues typically require the expenditure of significant resources and generate negative publicity, which could also have an adverse effect on our business, financial condition, and results of operations.

The Federal Health Insurance Portability and Accountability Act of 1996 (“HIPAA”), created additional federal criminal statutes that prohibit, among other actions, knowingly and willfully executing, or attempting to execute, a scheme to defraud any healthcare benefit program, including private third-party payors, knowingly and willfully embezzling or stealing from a healthcare benefit program, willfully obstructing a criminal investigation of a healthcare offense, and knowingly and willfully falsifying, concealing or covering up a material fact or making any materially false, fictitious or fraudulent statement in connection with the delivery of or payment for healthcare benefits, items or services. HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act (“HITECH”), and their implementing regulations, impose requirements regarding the privacy and security of individually identifiable health information, including mandatory contractual terms, for covered entities, or certain healthcare providers, health plans, and healthcare clearinghouses, and their business associates that provide services to the covered entity that involve individually identifiable health information and their subcontractors that use, disclose or otherwise process individually identifiable health information. HITECH also increased the civil and criminal penalties that may be imposed against covered entities and business associates and gave state attorneys general new authority to file civil actions for damages or injunctions in federal courts to enforce HIPAA. While pharmaceutical and biotechnology companies are typically not directly regulated by HIPAA, our business may be indirectly impacted by HIPAA in our interactions with providers, payors, and others that have HIPAA compliance obligations. We are also subject to state and foreign laws governing the privacy and security of health or personal information such as the European Union General Data Protection Regulation (“GDPR”) and the California Consumer Privacy Act of 2018 (“CCPA”).

There has been a recent trend of increased federal and state regulation of payments made to physicians and other healthcare providers. The Physician Payments Sunshine Act imposes annual reporting requirements on certain manufacturers of drugs, devices, biologics, and medical supplies for which payment is available under Medicare, Medicaid, or the Children’s Health Insurance Program, with specific exceptions, for payments made by them to physicians (defined to include doctors, dentists, optometrists, podiatrists and chiropractors) and teaching hospitals, as well as ownership and investment interests held by physicians and their immediate family members. Beginning in 2022, applicable manufacturers will also be required to report information related to payments and other transfers of value provided in the previous year to physician assistants, nurse practitioners, clinical nurse specialists, certified registered nurse anesthetists, and certified nurse midwives.

Within the European Union and the United Kingdom, payments made to physicians must be publicly disclosed. Moreover, agreements with physicians must in some countries be the subject of prior notification and approval by the physician’s employer, their competent professional organization, or the regulatory authorities of the individual country. These requirements are provided in the national laws, industry codes, or professional codes of conduct, applicable in the European Union Member States. Failure to comply with these requirements could result in reputational risk, public reprimands, administrative penalties, fines, or imprisonment.

Laws and regulations have been enacted by the federal government and various states to regulate the sales and marketing practices of pharmaceutical manufacturers with marketed products. The laws and regulations generally limit financial interactions between manufacturers and health care providers and/or require disclosure to the government and public of such interactions. Many of these laws and regulations contain ambiguous requirements or require administrative guidance for implementation. Given the lack of clarity in laws and their implementation, any future activities (if we obtain approval and/or reimbursement from federal healthcare programs for our product candidates) could be subject to challenge.

Manufacturing

Our primary manufacturing facility is located at our corporate headquarters at 20 Firstfield Road in Gaithersburg, Maryland. The facility has 53,000 square feet of combined GMP manufacturing and laboratory space. Our Rockville, Maryland facility houses our 10,000 square foot GMP pilot manufacturing facility that produces early-stage clinical trial material. Novavax AB, located in Uppsala, Sweden, produces our Matrix adjuvants in an approximately 24,000 square foot facility comprised of GMP manufacturing, laboratory and office space.

Given the significant global impact of the raw materialsCOVID-19 pandemic, it is possible that one or more government entities may take actions, including the U.S. government under the Defense Production Act of 1950, as amended, which could directly or indirectly have the effect of diminishing some of our rights or opportunities with respect to NVX-CoV2373 and other supplies requiredthe economic value of a COVID-19 vaccine to us could be limited. In addition, during a global health crisis, such as the COVID-19 pandemic, where the spread of a disease needs to be controlled, closed or heavily regulated national borders will create challenges and potential delays in our business are generally available from established vendors in quantities adequatedevelopment and production activities and may necessitate that we pursue strategies to meet our needs. In some cases, we have only qualified one vendor for certain of our manufacturing components. Prior to the initiation of commercial production, we plan, where feasible, to qualify multiple vendors of critical raw materials. One key vendor is GE Healthcare Company (“GEHC”), which supplies disposable components, resins, mediadevelop and buffers used in our manufacturing process. GEHC and other vendors that supply our key manufacturing materials have been or will be audited for compliance with GMP standards.

An important component of our Matrix adjuvant technology is extracted from a species of soap-bark tree (Quillaja saponaria) that grows mainly in Chile, and we have been able to acquire high-quality quillaja extract as needed from our current suppliers.

Business Development

We believe our proprietary vaccine technology affords us a range of traditional and non-traditional commercialization options that are broader than those of existing vaccine companies. We strive to create sustainable value by working to obtain non-dilutive funding, similar to our agreement with BMGF to fund our RSV program, that would allow for:

continued development ofproduce our vaccine candidates untilwithin self-contained national or international borders, at potentially much greater expense and with longer timeframes for public distribution.

We face an inherent risk of product liability as a result of the clinical testing of our product candidates and will face an even greater risk if we commercialize any products. For example, we may be sued if any product we develop allegedly causes injury or is found to be otherwise unsuitable during product testing, manufacturing, marketing or sale. Any such product liability claims may include allegations of defects in manufacturing, defects in design, a failure to warn of dangers inherent in the product, negligence, strict liability and a breach of warranties. Claims could also be asserted under state consumer protection acts. If we cannot successfully defend ourselves against product liability claims, we may incur substantial liabilities or be required to limit commercialization of our product candidates. In the United States, the Public
25

Readiness and Emergency Preparedness Act (the “PREP Act”), provides immunity for manufacturers from all claims under state or federal law for "loss" arising out of the administration or use of a “covered countermeasure.” However, injured persons may still bring a suit for "willful misconduct" against the manufacturer under some circumstances. "Covered countermeasures" include security countermeasures and "qualified pandemic or epidemic products", including products intended to diagnose or treat pandemic or epidemic disease, such as pandemic vaccines, as well as treatments intended to address conditions caused by such products. For these immunities to apply, the Secretary of DHHS must issue a declaration in cases of public health emergency or “credible risk” of a future public health emergency. On March 17, 2020, the Secretary of DHHS issued a declaration under the PREP Act and has issued subsequent amendments thereto since then to provide liability immunity for activities related to certain countermeasures against the ongoing COVID-19 pandemic. While we believe our products would be covered under the provisions of the PREP Act, this cannot be assured.

Also, there can be licensed;no assurance that the Secretary of the HHS will make other declarations in the future that cover any of our other product candidates or that the U.S. Congress will not act in the future to reduce coverage under the PREP Act or to repeal it altogether. If product liability lawsuits are brought against us, we may incur substantial liabilities and may be required to limit commercialization of our product candidates.

In addition to our aforementioned agreement with BMGF, another example of a strategic relationship is our joint venture we established with Cadila. CPLB is owned 20% by us and 80% by Cadila. It was established in 2009 to develop and manufacture certain vaccine candidates, biogeneric products and diagnostic products for the territory of India. CPLB operates a manufacturing facility in India for the production of vaccines and is actively developing a number of vaccine candidates that were genetically engineered by us.

RISKS RELATED TO OUR BUSINESS AND INDUSTRY

Summary of Risk Factors

Our business is subject to numerous risks. The following is a summary of the principal risk factors described in this section:

We have a history of losses and our future profitability is uncertain.


We will continue to require significant funding to maintain our current level of operations and fund the further development of our vaccine candidates.

Because our vaccine product development efforts depend on new and rapidly evolving technologies, our efforts may not succeed.

The regulatory and commercial success of our COVID-19 vaccine candidate, NVX-CoV2373, remains uncertain. While we have received provisional registration, conditional marketing authorization, or emergency use authorization for NVX-CoV2373 in a number of jurisdictions, we may be unable to obtain regulatory approvals in the United States or in any other jurisdiction or produce a successful vaccine in a timely manner, if at all.

We are a biotechnology company and face significant risk in developing, manufacturing, and commercializing our products.

Because we depend on third parties to conduct some of our laboratory testing and clinical trials, and a significant amount of our vaccine manufacturing and distribution, we may encounter delays in or lose some control over our efforts to develop and supply products.

Many of our competitors have significantly greater resources and experience, which may negatively impact our commercial opportunities and those of our current and future licensees.

There is significant competition in the development of a vaccine against COVID-19, influenza, and RSV and we may never see returns on the significant resources we are devoting to our vaccine candidates.

We may not succeed in obtaining the FDA licensure or foreign regulatory approvals necessary to sell our vaccine candidates.

Our products might fail to meet their primary endpoints in clinical trials, meaning that we will not have the clinical data required to support regulatory obligations.

The regulatory pathway for NVX-CoV2373 is continually evolving, and may result in unexpected or unforeseen challenges.

We have conducted, are conducting, and plan to conduct in the future, a number of clinical trials for NVX-CoV2373 at sites outside the United States and the FDA may not accept data from trials conducted in such locations.

29

The later discovery of previously unknown problems with a product, manufacturer, or facility may result in restrictions, including withdrawal of a vaccine that had previously received regulatory approval in certain jurisdictions from the market.

Our success depends on our ability to maintain the proprietary nature of our technology.

Our business may be adversely affected if we do not successfully execute our business development initiatives.

Servicing our 3.75% convertible senior unsecured notes due 2023 (the “Notes”) requires a significant amount of cash, and we may not have sufficient cash flow resources to pay our debt.

Because our stock price has been and will likely continue to be highly volatile, the market price of our common stock may be lower or more volatile than expected.

Litigation or regulatory investigations could have a material adverse impact on our results of operation and financial condition.

We or the third parties upon whom we depend may be adversely affected by natural or man-made disasters or public health emergencies, such as the COVID-19 pandemic.

Risks Related to Our Financial Condition and Capital Requirements

We have a history of losses and our future profitability is uncertain.

Our expenses have exceeded our revenue since our formation in 1987, and our accumulated deficit at December 31, 20182021 was $1.1$3.6 billion. Our revenue forand expenses fluctuate significantly from period to period.For most of our history our expenses have exceeded our revenue, which may occur during most periods in the last three fiscal years was $31.2 million in 2017, $15.4 million in 2016, and $36.3 million in 2015. We may not be successful in entering into strategic alliances or collaborative arrangements with other companies or government agencies that result in significant revenue to offset our expenses.foreseeable future. Our net losses for the last three fiscal years were $183.8$1.7 billion in 2021, $418.3 million in 2017, $280.02020, and $132.7 million in 2016, and $156.9 million in 2015.

Our recent historical2019.


Historically, our losses have resulted predominantly from research and development expenses for our vaccine candidates, manufacturing-related expenses, expenses associated with efforts to obtain regulatory approvals, costs related to protection of our intellectual property, and for other general and administrative operating expenses.expenses, a significant portion of which have been noncash. Our expenses have exceeded our revenue since inception, and we believe our expenses will fluctuate over time, and may substantially increase in some years, as a result of continuing research and development efforts to supportdevelop, test, manufacture, and make regulatory filings for our vaccine candidates, and, if our product candidates are approved, commercialization efforts.

As of the end of fiscal year 2021, our investment in the development efforts. In 2016,and manufacture of NVX-CoV2373 has been substantial, and we expect such levels of investment to continue for example, we experienced a significant increase in researchthe rest of 2022 and development expenses compared to prior years primarily due to additional RSV F Vaccine clinical trials in older adults and infants via maternal immunization, as well as higher employee-related costs to support developmentbeyond, although the precise magnitude of our RSV F Vaccinetotal investment will depend on the duration of the COVID-19 pandemic, the competitive landscape, the timing and other potential vaccine candidates.

Although certain specified costs associated with the developmentresults of our RSV F Vaccineapplications for infants via maternal immunization may be reimbursed underregulatory approvals, the availability of funding, and whether and what booster shot protocols are recommended by governments, regulatory authorities, and healthcare providers. If we are unable to timely commercialize a vaccine against COVID-19 in sufficient jurisdictions, we likely would never recoup our contract with BMGF, weinvestments. We expect to continue to incur significant operating expenses and anticipate significant losses over time as we seek to:

·conduct clinical trials for RSV F Vaccine and other potential vaccine candidates;
·conduct preclinical studies for other potential vaccine candidates;
·comply with the FDA’s manufacturing facility and compliance requirements in anticipation of commercialization;
·invest in our manufacturing process for commercial-scale and cost-efficiency; and
·maintain, expand and protect our intellectual property portfolio.


conduct additional clinical trials and seek regulatory approvals for NVX-CoV2373 and other potential vaccine candidates;

conduct preclinical studies for other potential vaccine candidates;

expand our global manufacturing and distribution capacity; and

maintain, expand and protect our intellectual property portfolio.

30

As a result, we expect our cumulative operating losses to increase until such time, if ever, that product sales, licensing fees, royalties, milestones, contract research and other sources generate sufficient revenue to fully fund our operations. We may never achieve profitability and may not sustain profitability, if achieved.


We have limited financial resources and we may not be ablewill continue to require significant funding to maintain our current level of operations or be able toand fund the further development of our vaccine candidates.


We do not expect tocurrently generate sufficient revenue from product sales, licensing fees, royalties, milestones, contract research or other sources in amounts sufficient to fully fund our operations for the foreseeable future, andoperations. We, therefore, we will therefore use our cash resources, and expect to require additional funds, to maintain our operations, continue our research and development programs, commence future preclinical studies and clinical trials, seek regulatory approvals and manufacture and market any products that are approved for commercialization.

To date, we have financed our products. We will seek suchoperations primarily through the sale of equity and debt securities, government funding and grant agreements, and additional fundsfunding may not be available to us on favorable terms, or at all. Although we have entered into supply agreements for NVX-CoV2373 that include prepayments from the purchasers, until we can generate sufficient product revenue in amounts sufficient to fully fund our operations, which we may never do, we expect to finance our cash needs through a combination of additional public or private equity or debt financings, collaborativeas well as existing cash, potential collaborations, strategic alliances and marketing, distribution or licensing arrangements, funding from governmental and development arrangements, non-dilutive government contractsnon-governmental funding entities, and grants andpotentially other sources. While we may continue to apply for contracts or grants from academic institutions, non-profit organizations and governmental entities, we may not be successful. Adequate additional funding may not be available to us on acceptable terms, if at all. Furthermore, negative interpretations of clinical trial data or setbacks, or perceived setbacks, with respect to manufacturing ability and/or capacity or regulatory filing timelines for NVX-CoV2373 or our other vaccine candidates, as well as the competitive landscape posed by other COVID-19 vaccines, may impair our ability to raise additional financing on favorable terms, or at all. Additionally, certain of the supply agreements for NVX-CoV2373 may be terminated by the counterparty if we do not timely achieve requisite regulatory approval for NVX-CoV2373 in the relevant jurisdictions under such agreements. If we cannot raise the additional funds required for our anticipated operations, we may be required to delay significantly, reduce the scope of or eliminate one or more of our research or development programs, downsize our general and administrative infrastructure,organization, or seek alternative measures to avoid insolvency, including arrangements with collaborative partners or others that may require us to relinquish rights to certain of our technologies or vaccine candidates. If we raise additional funds through future offerings of shares of our common stock or other securities, such offerings would cause dilution of current stockholders’ percentage ownership in the Company, which could be substantial. Future offerings also could have a material and adverse effect on the price of our common stock.

Economic uncertainty may adversely affect our access to capital, cost of capital and ability to execute our business plan as scheduled.


Generally, worldwide economic conditions remain uncertain.uncertain, particularly due to the COVID-19 pandemic. Access to capital markets is critical to our ability to operate. Traditionally, biotechnology companies have funded their research and development expenditures throughby raising capital in the equity markets. Declines and uncertainties in these markets in the past have severely restricted raising new capital and have affected companies’ ability to continue to expand or fund existing researchdevelopment, manufacturing, regulatory and developmentcommercialization efforts. We require significant capital for researchour current and development for our vaccine candidates and clinical trials.expected operations. The general economic and capital market conditions, both in the U.S. and worldwide, have been volatile in the past and at times have adversely affected our access to capital and increased the cost of capital. There is no certainty that theThe capital and credit markets willmay not be available to raise additionalsupport future capital raising activity on favorable terms. If economic conditions become worse,decline, our future cost of equity or debt capital and access to the capital markets could be adversely affected. In addition, if we are unable to access the capital markets on favorable terms, our ability to execute our business plan as scheduledcontemplated would be compromised. Moreover, we rely and intend to rely on third-parties,third parties, including clinical research organizations, contract manufacturing organizations and other important vendors and consultants. Global economic conditions may result in a disruption or delay in the performance of our third-party contractors and suppliers. If such third-partiesthird parties are unable to adequately satisfy their contractual commitments to us in a timely manner, our business could be adversely affected.

Even with the Grant Agreement with BMGF,


Our existing funding and supply agreements do not assure success of our vaccine candidates or that we may notwill be able to fully fund our RSV F Vaccine for infants via maternal immunization.

The GrantOWS Agreement, reimbursesthe DoD Agreement and the CEPI funding agreement each reimburse a portion of specifiedthe expenses associated with the development and commercialization of NVX-CoV2373. To the extent funding commitments in such agreements are conditioned on our RSV F Vaccine for infants via maternal immunization, and additional activities likely will be needed and BMGFmeeting certain milestones or conditions, including regulatory approval in applicable jurisdictions, we may not reimburseultimately receive the full amount of committed funds and could be exposed to urgent need for additional funding to support our NVX-CoV2373 development, manufacturing and distribution activities. For example, in

The OWS Agreement includes provisions giving the USG termination rights based on a determination that the funded project will not produce beneficial results commensurate with the expenditure of resources and that termination would be licensedin the USG’s interest. Such a determination would result in the loss of funding under that agreement and could result in other actions by the FDA.

U.S. government. The Grant Agreement reimbursesCEPI funding agreement provides CEPI certain “march-in” rights in the event of certain breaches of that agreement. We may be unable to timely obtain additional government or private funding, if at all. Additionally, we have entered into, and plan to continue entering into, supply agreements for NVX-CoV2373 that include prepayments from the purchasers. Certain of the supply agreements may be terminated by the counterparty if we do not timely achieve requisite regulatory approval for NVX-CoV2373 in the relevant jurisdictions under such agreements. In the event we are unable to successfully develop and commercialize NVX-CoV2373 or fail to meet certain regulatory milestones or product volume or delivery timing obligations under our supply agreements, we may be required to refund significant portions of the prepayments, which could have a portion of specified expenses associated with the development ofmaterial and adverse effect on our RSV F Vaccine for infants via maternal immunization, but we remain fully responsible for conducting these development activities.

Risks Related to Product Development and Commercialization

Because our vaccine product development efforts depend on new and rapidly evolving technologies, our efforts may not succeed.

Our vaccine development efforts depend on new, rapidly evolving technologies and on the marketability and profitability of our wholly owned subsidiary Novavax AB,products. Our development efforts and, if those are successful, commercialization of NVX-CoV2373 and our other vaccines could fail for a variety of reasons, including if:

our recombinant nanoparticle vaccine technologies, any or all of the products based on such technologies or our proprietary manufacturing process prove ineffective or unsafe;

new strains of COVID-19 evolve, with regionalrespect to which NVX-CoV2373 proves less effective;

we or our third-party manufacturer facilities fail to reproducibly scale-up manufacturing with sufficiently high yields at reasonable cost and on projected timelines, or such manufacturing fails to generate product that consistently satisfies purity, potency, quality, stability, and shelf-life standards necessary for obtaining regulatory approvals or achieving commercial viability;

the products are difficult to manufacture on a large-scale or uneconomical to market;

some or all of the products that we or our third-party partners suchhave manufactured may be determined to be unsalable based on criteria imposed by regulators as Cadilathey complete regulatory approvals;

our in-house or third-party manufacturing facilities fail regulatory inspections;

proprietary rights of third-parties prevent us or our collaborators from exploiting technologies, and BMGF,manufacturing or marketing products; or

third-party competitors achieve and maintain greater market share due to earlier approvals or superior marketing capabilities.

The regulatory and commercial success of our COVID-19 vaccine candidate, NVX-CoV2373, remains uncertain. While we have received provisional registration, conditional marketing authorization or emergency use authorization for NVX-CoV2373 in a number of jurisdictions, we may be unable to obtain any other regulatory approvals in the United States or other jurisdictions or produce a successful vaccine in a timely manner, if at all.

In response to the outbreak of COVID-19, we are pursuing the development and manufacture of our vaccine candidate, NVX-CoV2373. Even though we have reported positive data from Phase 1, 2 and 3 clinical trials, and have
32

received provisional registration, conditional marketing authorization, or emergency use authorization from the World Health Organization and in Canada, Australia, New Zealand, the E.U., the United Kingdom, India, Indonesia, the Philippines, and Singapore, as well as full approval in South Korea, such results may not be sufficient to support regulatory submissions, authorizations and approvals, accelerated or otherwise, in any other relevant jurisdictions on our projected timelines, if at all.

Additionally, even though NVX-CoV2373 has received regulatory approval in certain jurisdictions and may receive further regulatory approval in others, successful commercialization depends on our ability to effectively scale up manufacturing capabilities at our own locations and those of our manufacturing partners and contractors. In May 2020, we acquired Novavax CZ (formerly Praha Vaccines, a.s.) including its vaccine manufacturing facility in Bohumil, Czech Republic and approximately 150 of its employees. We also are actively entering into agreements with international providers, exposethird parties to manufacture the antigen component of NVAX-CoV2373 and our proprietary Matrix-Madjuvant, as well as to distribute NVX-CoV2373. Because of contractual restraints and the limited number of third-party manufacturers with the expertise, required regulatory approvals and facilities to manufacture NVX-CoV2373 and its components at commercial scale, replacement of a manufacturer may be expensive and time-consuming and may cause interruptions in production. Manufacturing of NVX-CoV2373 and its components involves a complicated process that will require significant investments of time and financial resources to implement, and our efforts to establish manufacturing capabilities may not meet expectations as to timing, scale-up, reproducibility, yields, purity, cost, potency or quality. Shortages of raw materials and supplies also negatively impact our manufacturing efforts. We may not be able to timely and effectively produce NVX-CoV2373 in adequate quantities to address global demand.

We have not previously had a commercial launch of any vaccine product, and doing so in a pandemic environment with an urgent, critical global need creates additional challenges. In addition to scaling up our manufacturing capabilities, we need to develop global distribution channels and form partnerships with third parties worldwide, as well as hire, train and integrate additional management, administrative and sales and marketing personnel. Rapid and significant growth may strain our administrative and operational infrastructure, imposing significant additional responsibilities on our organization, and our efforts to establish these capabilities may not meet expectations as to timing, scale-up, reproducibility, yields, purity, cost, potency or quality. If we fail to successfully manage our growth and the increased complexity of our operations, our business, financial position, results of operations and prospects may be materially and adversely affected.

We are a biotechnology company and face significant risk in developing, manufacturing and commercializing our products.

We focus our research and development activities on vaccines, an area in which we believe we have particular strengths and a technology that appears promising. The outcome of any research and development program is highly uncertain. Only a small fraction of biopharmaceutical development programs ultimately result in commercial products or even product candidates and a number of events could delay our development efforts and negatively impact our ability to make regulatory submissions or obtain regulatory approval for, and to manufacture, market and sell, NVX-CoV2373 or any other vaccine on our projected timelines, if at all. Vaccine candidates that initially appear promising often fail to yield successful products, and we may not ultimately be able to demonstrate the safety, potency, purity, stability and efficacy necessary to obtain or maintain regulatory authorization to market our product candidates. In many cases, preclinical studies or clinical trials will show that a product candidate is not efficacious or that it raises safety concerns or has other side effects that outweigh its intended benefit. Success in preclinical or early clinical trials may not translate into success in large-scale clinical trials. Further, success in clinical trials often leads to increased investment, accelerating cumulative losses. Even if clinical trial results appear positive, regulatory approval may not be obtained if the FDA, or a foreign equivalent, does not agree with our interpretation of the results, and we may face challenges when scaling-up the production process to commercial levels. Even after a product is approved and launched, general usage or post-marketing clinical trials may identify safety or other previously unknown problems with the product, or manufacturing issues may emerge, either of which may result in regulatory approvals being suspended, limited to narrow the scope of the approval, or revoked, which may otherwise prevent successful commercialization. Intense competition in the vaccine industry could also limit the successful commercialization of any products for which we receive commercial approval.

We will require approval from the FDA of any name we intend to use for our products regardless of whether we have secured a trademark registration from the USPTO. The FDA typically conducts a review of proposed product names, including an evaluation of potential for confusion with other product names. The FDA may object to any product name we submit if it believes the name inappropriately implies medical claims. If the FDA objects to any of our proposed product names, we may be required to adopt an alternative name for our proposed products. If we adopt an alternative name, we would lose the benefit of any existing trademark applications for such developmental candidate and may be required to expend significant additional resources in an effort to identify a suitable product name that would qualify under applicable trademark laws, not infringe the existing rights of third parties and be acceptable to the FDA. We may be unable to build a
33

successful brand identity for a new trademark in a timely manner or at all, which would limit our ability to commercialize our products, if approved.

Because we depend on third parties to conduct some of our laboratory testing and clinical trials, and a significant amount of our vaccine manufacturing and distribution, we may encounter delays in or lose some control over our efforts to develop and supply products.

We are highly dependent on third-party organizations to conduct some of our laboratory testing and clinical trials and a significant amount of our vaccine manufacturing activities and distribution. If we are unable to obtain any necessary services on acceptable terms, we may not complete our product development or commercialization efforts in a timely manner. We may lose control over these activities or become too dependent upon these parties. These third parties may not complete testing, manufacturing or distribution activities on schedule, or in satisfaction of regulatory or commercial requirements. Certain of our facilities are also contracted for defined time frames and through association with OWS and CEPI, and we may not be able to access those facilities for sufficient periods of time to provide adequate supply.

We are responsible for confirming that each of our clinical trials is conducted in accordance with its general investigational plan and protocol. Moreover, the FDA and foreign regulatory agencies require us to comply with regulations and standards, commonly referred to as good clinical practices, for conducting, recording and reporting the results of clinical trials to assure that data and reported results are credible and accurate and that the rights, safety and welfare of clinical trial participants are adequately protected. The FDA and foreign regulatory agencies also require us to comply with good manufacturing practices. Our reliance on third parties does not relieve us of these responsibilities and requirements. These third parties may not successfully carry out their contractual duties or regulatory obligations. Furthermore, if a third-party manufacturer is producing materials or products for themselves or other companies, that manufacturer is exposed to regulatory risks for the production of such materials and products. As a result, failure to meet the regulatory requirements for the production of those materials and products may generally affect the regulatory status of the third-party manufacturer’s facility, which could impact its ability to produce our materials and products. Any of our third-party service providers may need to be replaced, the quality or accuracy of the data they obtain may be compromised, the services provided to us may be delayed, or the product they manufacture may be contaminated due to the failure to adhere to our clinical and manufacturing protocols, regulatory requirements or for other reasons. In any such event, our preclinical development activities or clinical trials may be extended, delayed, suspended or terminated, and we may not be able to obtain regulatory approval of, or successfully commercially manufacture on a timely basis, our vaccine candidates.

The results from the Prepare trial, including that ResVax failed to meet the primary endpoint of the trial, will likely create challenges, some of which may be significant, around further development of that vaccine.

While the Prepare results suggest that ResVax, the project name for the RSV vaccine candidate, is safe and is likely efficacious in more serious manifestations of RSV disease, the trial failed to achieve its primary clinical endpoint. Not achieving the primary clinical endpoint has been viewed negatively by our investors. Although the failure to achieve the primary endpoint in the trial is not evidence that the vaccine is ineffective, it means that regulatory agencies like the FDA and EMA are likely to require additional risks associated with doingclinical trial data prior to licensure. This development may be viewed negatively by our potential collaborators and partners, which may make the ongoing development of ResVax, and any other RSV F Vaccine candidates, more challenging.

We may have product liability exposure.

The administration of drugs or vaccines to humans, whether in clinical trials or after marketing approval, can result in product liability claims. We maintain product liability insurance coverage for our current clinical programs, including our NVX-CoV2373 trials, and we have expanded our insurance coverage to include the sale of commercial products. However, we may not be able to obtain additional insurance coverage or maintain insurance coverage on commercially reasonable terms, at a reasonable cost or in sufficient amounts to protect us against losses due to liability. Furthermore, such insurance coverage and our resources may not be sufficient to satisfy all liabilities that result from product liability claims. A successful claim may prevent us from obtaining adequate product liability insurance in the future on commercially desirable terms, if at all. Even if a claim is not successful, defending such a claim would be time- consuming and expensive, may damage our reputation in the marketplace and would likely divert management’s attention.

In addition, because we are developing NVX-CoV2373 in response to the outbreak of COVID-19, a global pandemic, we have received provisional registration, conditional marketing authorization or emergency use authorization from the World Health Organization and in Canada, Australia, New Zealand, the E.U., the United Kingdom, India, Indonesia, the Philippines, and Singapore, as well as full authorization in South Korea, and we may have a widely used vaccine as an investigational vaccine or a product authorized for temporary or emergency use prior to our receipt of marketing approval in
34

other jurisdictions as well. Unexpected safety issues in these circumstances could lead to product liability claims and our existing insurance may not be adequate for such claims.

Regardless of merit or eventual outcome, liability claims may result in:

decreased demand for our products;

withdrawal of regulatory approvals;

voluntary or mandatory recalls of our products;

necessity for additional nonclinical or clinical studies, changes in labeling, or changes to manufacturing processes, specifications and/or facilities;

impairment of our business outsidereputation and negative media attention;

withdrawal of clinical trial participants;

costs of related litigation;

substantial monetary awards to participants or other claimants;

loss of revenue; and

inability to commercialize our vaccine candidates.

In the United States, the PREP Act provides immunity for manufacturers from all claims under state or federal law for “loss” arising out of the administration or use of a “covered countermeasure.” However, injured persons may still bring a suit for “willful misconduct” against the manufacturer under some circumstances. “Covered countermeasures” include security countermeasures and “qualified pandemic or epidemic products”, including products intended to diagnose or treat pandemic or epidemic disease, such as pandemic vaccines, as well as treatments intended to address conditions caused by such products. For these immunities to apply, the Secretary of DHHS must issue a declaration in cases of public health emergency or “credible risk” of a future public health emergency. On March 17, 2020, the Secretary of DHHS issued a declaration under the PREP Act and has issued subsequent amendments thereto to provide liability immunity for activities related to certain countermeasures against the ongoing COVID-19 pandemic. While we believe our products would be covered under the provisions of the PREP Act, this cannot be assured. Also, the Secretary of the HHS may not make other declarations in the future that cover any of our other product candidates, and the U.S.

Swedish-based Congress may reduce coverage under the PREP Act or repeal it altogether. Product liability lawsuits may result in substantial liabilities and may require us to limit commercialization of our product candidates.


If we are unable to effectively manufacture our vaccines in sufficient quantities, at sufficient yields or are unable to obtain regulatory approvals for a manufacturing facility for our vaccines, we may experience delays or an adverse impact on product development, clinical trials, regulatory approval and commercial distribution.

Completion of our clinical trials and commercialization of our vaccine candidates require access to, or development of, facilities to effectively manufacture our vaccine candidates at sufficient yields and at commercial-scale. We have limited experience manufacturing any of our vaccine candidates in the volumes necessary to support commercial sales. While we have recently increased our projected global manufacturing capacity for NVX-CoV2373, our efforts to establish manufacturing capabilities may not meet expectations as to timing, scale-up, reproducibility, yields, purity, cost, potency or quality. The antigen component of NVX-CoV2373 is currently being manufactured at Novavax AB is a wholly owned subsidiary of Novavax, Inc. We also have formed a joint venture with CadilaCZ, as well as numerous partnered manufacturing sites, including FUJIFILM in the United States, SIIPL in India, SK bioscience in Korea, and Takeda in Japan, among others.Challenges manufacturing either the antigen component or the adjuvant, or issues in later manufacturing stages, could compromise production of NVX-CoV2373.

Manufacturing our vaccine candidates involves a complicated process with which we have establishedlimited experience. We are highly dependent on third-party organizations to conduct a significant amount of our vaccine manufacturing activities. If
35

we and our third-party manufacturing organizations are unable to manufacture our vaccine candidates in clinical development agreement with BMGFquantities or, if and have entered into other agreementswhen necessary, in commercial quantities and at sufficient yields and at required specifications, then commercialization will be delayed, and we will need to identify and reach supply arrangements with companiesadditional third parties. Third-party manufacturers also must receive FDA or equivalent foreign regulatory body approval before they can produce clinical material or commercial product. Our vaccines are in competition with other countries.products for access to these third-party facilities and may be subject to delays in manufacture if third parties prioritize other products. We plan to continuemay not be able to enter into collaborationsany necessary additional third-party manufacturing arrangements on acceptable terms, or partnershipson a timely basis. In addition, we have to enter into technical transfer agreements and share our know-how with companies, non-profit organizationsthe third-party manufacturers, which can be time-consuming and local governmentsmay result in various partsdelays.

Because of contractual restraints and the world. Riskslimited number of conducting business outsidethird-party manufacturers with the U.S. include negative consequences of:

·the costs associated with seeking to comply with multiple regulatory requirements that govern our ability to develop, manufacture and sell products in local markets;
·failure to comply with anti-bribery laws such as the U.S. Foreign Corrupt Practices Act and similar anti-bribery laws in other jurisdictions;
·existing, new or changes in interpretations of existing trade protections measures, including tariffs, and import and export licensing requirements;
·difficulties in and costs of staffing, managing and operating our international operations;
·changes in environmental, health and safety laws;
·fluctuations in foreign currency exchange rates;
·new, changes in or changes in interpretations of tax laws;
·political instability and actual or anticipated military or potential conflicts;
·economic instability, inflation, recession and interest rate fluctuations;
·minimal or diminished protection of intellectual property in many jurisdictions; and
·possible nationalization and expropriation.

16

These risks, individually orexpertise, required regulatory approvals and facilities to manufacture our bulk vaccines at commercial-scale, replacement of a manufacturer may be expensive and time-consuming and may cause interruptions in the aggregate,production of our vaccine. We and our third-party manufacturers may also encounter production challenges related to:


costs, scale up, and yields;

shortages of raw materials and supplies;

quality control and assurance;

contamination, lot consistency, potency, and purity;

shortages of qualified personnel and other capacity constraints;

compliance with strictly enforced and evolving federal, state and foreign regulations that vary in each country where products might be sold including nationalization or other territory restrictions placed on our owned and third-party manufacturing sites; and

capital funding.

Delays or interruptions could have a material adverse effect on our business, financial conditions,condition, results of operations and cash flows.


We must identify vaccines for development with our technologies and establish successful third-party relationships.

The near and long-term viability of our vaccine candidates depend in part on our ability to successfully establish new strategic collaborations with pharmaceutical and biotechnology companies, non-profit organizations and government agencies. Establishing strategic collaborations and obtaining government funding is difficult and time-consuming. Potential collaborators may reject collaborations based upon their assessment of our financial, regulatory or intellectual property position or based on their internal pipelines; government agencies may reject contract or grant applications based on their assessment of public need, the public interest, our products’ ability to address these areas, or other reasons beyond our expectations or control. Collaborators also may seek to modify or terminate relationships.Past success in establishing strategic collaborations with pharmaceutical and biotechnology companies, non-profit organizations and government agencies in the past is no guarantee of future success in entering into new relationships or in performing under existing relationships. If we fail to establish a sufficient number of collaborations or government relationships on acceptable terms, or fail to perform under collaborations or relationships to the satisfaction of counter-parties, we may not be able to commercialize our vaccine candidates or generate sufficient revenue to fund further research and development efforts.

The collaborations we have established or may establish may not result in the successful development or commercialization of any vaccine candidates for several reasons, including the fact that:

we may not have the ability to control the activities of our partners and cannot provide assurance that they will fulfill their obligations to us, including with respect to the license, development and commercialization of vaccine candidates, in a timely manner or at all;
36


such partners may not devote sufficient resources to our vaccine candidates or properly maintain or defend our intellectual property rights;

our partners could independently develop, or develop with third parties, products that compete directly or indirectly with our vaccine candidates if such partners believe that competitive products are more likely to be successfully developed or can be commercialized under terms that are more economically attractive than ours;

any failure on the part of our partners to perform or satisfy their obligations to us could lead to delays in the development or commercialization of our vaccine candidates and affect our ability to realize product revenue; and

disagreements, including disputes over the ownership of technology developed with such collaborators, could result in litigation, which would be time consuming and expensive, and may delay or terminate research and development efforts, regulatory approvals and commercialization activities.

If we or our collaborators fail to maintain our existing agreements or in the event we fail to establish agreements as necessary, we could be required to undertake research, development, manufacturing and commercialization activities solely at our own expense. These activities would significantly increase our capital requirements and, given our lack of sales, marketing and distribution capabilities, significantly delay the commercialization of our vaccine candidates.

Even though we have received provisional registration, conditional marketing authorization or emergency use authorization in certain jurisdictions for NVX-CoV2373, and even if we have products licensed in additional markets, our vaccine products may not be initially or ever profitable.

Whether we make a profit from the sale of our vaccine products is dependent on a number of variables, including the costs we incur manufacturing, testing and releasing, packaging and shipping such vaccine product. Additionally, the CEPI funding agreement necessitates that we allocate a certain number of doses of NVX-CoV2373 to certain middle and lower income countries, and the Grant Agreement with BMGF necessitates that we commit to a specific amount of sales in certain specified middle and lower income countries, which may impact negatively our ability to generate profit. We cannot predict when, if at all, our approved vaccine products will be profitable to the Company.

Even if we successfully commercialize any of our vaccine candidates, either alone or in collaboration, we face uncertainty with respect to pricing, third-party reimbursement and healthcare reform, all of which could adversely affect any commercial success of our vaccine candidates.

Our ability to collect revenue from the commercial sale of our vaccines may depend on our ability, and that of any current or potential future collaboration partners or customers, to obtain adequate levels of approval, coverage and reimbursement for such products from third-party payers such as:

government health administration authorities such as the Advisory Committee for Immunization Practices of the Centers for Disease Control and Prevention;

private health insurers;

managed care organizations;

pharmacy benefit management companies; and

other healthcare related organizations.

Third-party payers are increasingly challenging the prices charged for medical products and may deny coverage or offer inadequate levels of reimbursement if they determine that a prescribed product has not received appropriate clearances from the FDA, or foreign equivalent, or other government regulators; is not used in accordance with cost-effective treatment methods as determined by the third-party payer; or is experimental, unnecessary or inappropriate. Prices could also be driven down by managed care organizations that control or significantly influence utilization of healthcare products.
37


In both the U.S. and some foreign jurisdictions, there have been a number of legislative and regulatory proposals and initiatives to change the health care system in ways that could affect our ability to sell vaccines and could adversely affect the prices that we receive for our vaccine candidates, if approved. Some of these proposed and implemented reforms could result in reduced pharmaceutical pricing or reimbursement rates for medical products, and while we have no current vaccines available for commercial sale other than subject to provisional registration, conditional marketing authorization or emergency use authorization in certain foreign jurisdictions, the impact of such reform could nevertheless adversely affect our business strategy, operations and financial results. For example, the Affordable Care Act (“ACA”) contained several cost containment measures that could adversely affect our future revenue, including, for example, increased drug rebates under Medicaid for brand name prescription drugs, extension of Medicaid rebates to Medicaid managed care organizations, and extension of so-called 340B discounted pricing on pharmaceuticals sold to certain healthcare providers. Additional provisions of the healthcare reform laws that may negatively affect our future revenue and prospects for profitability include the assessment of an annual fee based on our proportionate share of sales of brand name prescription drugs to certain government programs, including Medicare and Medicaid. The ACA also established a Medicare Part D coverage gap discount program, in which manufacturers must agree to offer 70% point-of-sale discounts off negotiated prices of applicable branded on drugs (including vaccines) to eligible beneficiaries during their coverage gap period (the so-called “donut hole”), as condition for the manufacturer’s outpatient drugs to be covered under Medicare Part D. Other aspects of healthcare reform, such as expanded government enforcement authority and heightened standards that could increase compliance-related costs, could also affect our business.

Further, we face uncertainties because of occasional political, legislative, and administrative efforts to substantially modify or invalidate some or all of the provisions of the ACA. For example, in 2017, the Trump administration withheld the cost-sharing subsidies paid to ACA health insurance exchange plans serving low-income enrollees. The Tax Cut and Jobs Act (“TCJA”) was also enacted at the end of 2017 and included provisions that affected healthcare insurance coverage and payment, such as the elimination of the tax penalty for individuals who do not maintain sufficient health insurance coverage beginning in 2019 (the so-called “individual mandate”).

More recently, the Biden administration, through the American Rescue Plan Act of 2021, increased subsidies for coverage purchased through ACA health insurance exchanges and extended eligibility for subsidies to higher income levels. On December 14, 2018, a U.S. District Court Judge in the Northern District of Texas ruled that the individual mandate is a critical and inseverable feature of the ACA, and therefore, because it was repealed as part of the TCJA, the remaining provisions of the ACA are invalid as well. On December 18, 2019, the U.S. Court of Appeals for the 5th Circuit ruled that the individual mandate was unconstitutional but remanded the case back to the District Court to determine whether the remaining provisions of the ACA are invalid as well. On March 2, 2020, the U.S. Supreme Court granted the petitions for writs of certiorari to review the case, and oral arguments were heard on November 10, 2020. On June 17, 2021, the U.S. Supreme Court dismissed the most recent judicial challenge to the ACA brought by several states without specifically ruling on the constitutionality of the ACA. Separately, President Biden issued an Executive Order to initiate a special enrollment period from February 15, 2021 through August 15, 2021 for purposes of obtaining health insurance coverage through the ACA marketplace. The Executive Order also instructed certain governmental agencies to review and reconsider their existing policies and rules that limit access to healthcare, including among others, reexamining Medicaid demonstration projects and waiver programs that include work requirements, and policies that create unnecessary barriers to obtaining access to health insurance coverage through Medicaid or the ACA. It is also unclear how these and other healthcare reform measures of the Biden administration or other efforts, if any, to challenge, repeal or replace the ACA, will impact our business.

Other legislative changes have been proposed and adopted since the ACA was enacted. These changes include aggregate reductions to Medicare payments to providers of 2% per fiscal year pursuant to the Budget Control Act of 2011 and subsequent laws, which began in 2013 and, due to subsequent legislative amendments, will stay in effect through 2030 unless additional Congressional action is taken. In January 2013, the American Taxpayer Relief Act of 2012 was signed into law, which, among other things, further reduced Medicare payments to several types of providers, including hospitals, imaging centers and cancer treatment centers, and increased the statute of limitations period for the government to recover overpayments to providers from three to five years. New laws may result in additional reductions in Medicare and other healthcare funding, which may materially adversely affect customer demand and affordability for our products and, accordingly, the results of our financial operations. Additionally, the pharmaceutical industry has also been the subject of significant publicity in recent years regarding the pricing of pharmaceutical products, including publicity and pressure resulting from prices charged by pharmaceutical companies for new products as well as price increases by pharmaceutical companies on older products that some people have deemed excessive. As a result, pharmaceutical product prices have been the focus of increased scrutiny by the U.S. government, including certain state attorneys general, members of congress, presidential candidates and the United States Department of Justice. If reforms in the health care industry make reimbursement for our potential products less likely, the market for our potential products will be reduced, and we could lose potential sources of revenue. The existence or threat of cost control measures could cause our corporate collaborators to be less willing or able to pursue research and development programs related to our vaccine candidates. Further, it is also possible
38

that additional governmental action is taken in response to the COVID-19 pandemic. We cannot predict the ultimate content, timing or effect of any healthcare reform legislation or the impact of potential legislation on us.

Even if we receive regulatory approvals for our vaccine candidates, including NVX-CoV2373, coverage and reimbursement may be subject to unique regulatory policies. For example, under the ACA preventive care mandate, non-grandfathered group health plans and health insurance coverage offered in the individual or group market typically have at least one year before they must provide first-dollar coverage for a newly issued preventive care requirement or guideline. However, pursuant to the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”), non-grandfathered group health plans and health insurance coverage offered in the individual or group market must cover any qualifying coronavirus preventive service 15 business days after the United States Preventive Services Task Force, or Advisory Committee on Immunization Practices (ACIP) designates such service as preventive. Further, third-party reimbursement for providers administering COVID-19 vaccines may affect market acceptance of NVX-CoV2373, if we receive regulatory approval. Currently, the CARES Act and its implementing regulations state that (i) providers that participate in the U.S. Centers for Disease Control and Prevention’s COVID-19 Vaccination Program must administer a COVID-19 immunization regardless of an individual’s ability to pay or health insurance coverage status, (ii) providers may not seek any reimbursement, including through balance billing, from an immunization recipient, (iii) coverage is required, without cost-sharing, for the administration of the immunization even if a third party, such as the federal government, pays for the cost of the immunization, and (iv) private health insurance plans must cover COVID-19 immunizations and their administration even when provided by out-of-network providers for the duration of the public health emergency for COVID-19. Even if we receive regulatory approvals for NVX-CoV2373, there is no guarantee payors will provide coverage and reimbursement for our product after the termination of the public health emergency, nor can we guarantee that even if coverage is provided, the reimbursement amount will be high enough to allow us to establish or maintain pricing sufficient to realize a sufficient return on our investment. We cannot predict continued prevalence of COVID-19, whether herd immunity will be achieved (which would affect the need for future administration of COVID-19 vaccines), or whether NVX-CoV2373 will be effective against continuing mutations or variants of the SARS-CoV-2 virus.

We have limited marketing capabilities, and if we are unable to enter into collaborations with marketing partners or develop our own sales and marketing capability, we may not be successful in commercializing any approved products.

Although we have initiated preliminary activities in anticipation of commercialization of our vaccine candidates, we currently have limited dedicated sales, marketing or distribution capabilities. As a result, we depend on collaborations with third parties that have established distribution systems and sales forces, including our collaboration with SIIPL, among others. To the extent that we enter into co-promotion or other licensing arrangements, our revenue will depend upon the efforts of third parties, over which we may have little or no control. If we are unable to reach and maintain agreements with one or more pharmaceutical companies or collaborators, we may be required to market our products directly. Developing a marketing and sales force is expensive and time-consuming and could delay a product launch. We may not be able to attract and retain qualified sales personnel or otherwise develop this capability.

Our vaccine candidates may never achieve market acceptance even if we obtain regulatory approvals.

Even if we receive regulatory approvals for the commercial sale of our vaccine candidates, the commercial success of these vaccine candidates will depend on, among other things, their acceptance by physicians, patients and third-party payers, such as health insurance companies and other members of the medical community, as a vaccine and cost-effective alternative to competing products. If our vaccine candidates fail to gain market acceptance, we may be unable to earn sufficient revenue to continue our business. Market acceptance of, and demand for, any product that we may develop and commercialize will depend on many factors, including:

our ability to provide acceptable evidence of safety and efficacy (including against emerging COVID-19 variants);

the prevalence and severity of adverse side effects;

whether our vaccines are differentiated from other vaccines;

availability, relative cost and relative efficacy of alternative and competing treatments;

the effectiveness of our marketing and distribution strategy;

publicity concerning our products or competing products and treatments; and
39


our ability to obtain sufficient third party insurance coverage or reimbursement.

If our vaccine candidates do not become widely accepted by physicians, patients, third-party payers and other members of the medical community, our business, financial condition and results of operations could be materially and adversely affected.

We may not be able to secure sufficient supplies of a key component of our adjuvant technology.

Because an important component of our adjuvant technology is extracted from a species of soap-bark tree (Quillaja saponaria) grown in Chile, we need long term access to quillaja extract with a consistent and sufficiently high quality. We need a secure supply of raw material, as well as back-up suppliers, or our adjuvant products may be delayed and we may not be able to meet our obligations under our various collaboration and supply agreements.

Current or future regional relationships may hinder our ability to engage in larger transactions.


We have entered into regional collaborations to develop, manufacture and distribute our vaccine candidates in certain parts of the world, and we may enteranticipate entering into additional regional collaborations. Our relationships with CadilaSIIPL, Takeda, SK bioscience and BMGF are examples of these regional relationships. These relationships often involve the licensing of our technology to our partner or entering into a distribution agreement, frequently on an exclusive basis. Generally, exclusive agreements are restricted to certain territories. Because we have entered into exclusive license and distribution agreements, larger companies may not be interested, or able, to enter into collaborations with us on a worldwide-scale. Also, these regional relationships may make us an unattractive target for an acquisition.

We are a biotechnology company and face significant risk in developing, manufacturing and commercializing our products.

We focus our research and development activities on vaccines, an area in which we believe we have particular strengths and a technology that appears promising. The outcome of any research and development program is highly uncertain. Only a small fraction of biopharmaceutical development programs ultimately result in commercial products or even


Our product candidates are sensitive to shipping and astorage conditions, which could subject our vaccine candidates to risk of loss or damage.

Our vaccine candidates are sensitive to storage and handling conditions. Loss in vaccine candidates could occur if the product or product intermediates are not stored or handled properly. It is possible that our vaccine candidates could be lost due to expiration prior to use. If we do not effectively maintain our supply logistics, then we may experience an unusual number of eventsreturned or out of date products. Failure to effectively maintain our supply logistics, by us or third parties, could delay our development effortslead to additional manufacturing costs and negatively impactdelays in our ability to obtain regulatory approvalsupply required quantities for and to manufacture, market and sell, a vaccine. Vaccine candidates that initially appear promising often fail to yield successful products. In many cases, preclinical studies or clinical trials will show thator otherwise.

Our vaccine candidates could become subject to a product candidate is not efficacious or that it raises safety concerns or has other side effects that outweigh its intended benefit. Successrecall which could harm our reputation, business, and financial results.

The FDA and similar foreign governmental authorities have the authority to require the recall of certain vaccine candidates. Manufacturers may, under their own initiative, recall a product if any material deficiency in preclinical or early clinical trials may not translate into success in large-scale clinical trials. Further, success in clinical trials often leads to increased investment, accelerating cumulative losses. Even if clinical trial results appear positive, regulatory approval may not be obtained if the FDA does not agree with our interpretation of the results, and we may face challenges when scaling-up the production process to commercial levels. Even after a product is approved and launched, general usagefound. A government-mandated or post-marketing clinical trials may identify safetyvoluntary recall by us or our strategic collaborators could occur as a result of manufacturing errors, design or labeling defects or other previously unknown problems with the product, which may result in regulatory approvals being suspended, limited to narrow indications or revoked, which may otherwise prevent successful commercialization. Intense competition in the vaccine industry could also limit the successful commercializationdeficiencies and issues. Recalls of any products for which we receive commercial approval.

of our vaccine candidates would divert managerial and financial resources and have an adverse effect on our financial condition and results of operations. A recall announcement could harm our reputation with customers and negatively affect our sales, if any.


Risks Related to Our Industry and Competition

Many of our competitors have significantly greater resources and experience, which may negatively impact our commercial opportunities and those of our current and future licensees.


The biotechnology and pharmaceutical industries are subject to intense competition and rapid and significant technological change. We have many potential competitors, including major pharmaceutical companies, specialized biotechnology firms, academic institutions, government agencies and private and public research institutions. Many of our competitors have significantly greater financial and technical resources, experience and expertise in:

·research and development;
·preclinical testing;
·designing and implementing clinical trials;
·regulatory processes and approvals;
·production and manufacturing; and
·sales and marketing of approved products.

an organization’s intellectual property portfolio;

the range of capabilities, from target identification and validation to drug discovery and development to manufacturing and marketing; and

the availability of substantial capital resources to fund discovery, development and commercialization activities.

Large and established companies, such as Merck & Co., Inc., GlaxoSmithKline plc, CSL Ltd,Ltd., Sanofi Pasteur, SA, Pfizer Inc., Johnson & Johnson, AstraZeneca, and MedImmune,Moderna, among others, compete in the vaccine market. In particular, these companies have greater experience and expertise in securing government contracts and grants to support their research and development efforts, conducting testing and clinical trials, obtaining regulatory approvals to market products, manufacturing such products on a broad scale and marketing approved products.


Regardless of the disease, smaller or early-stage companies and research institutions also may prove to be significant competitors, particularly through collaborative arrangements with large and established pharmaceutical companies. As these companies develop their technologies, they may develop proprietary positions, which may prevent or limit our product development and commercialization efforts. We will also face competition from these parties in recruiting and retaining qualified scientific and management personnel, establishing clinical trial sites and participant registration for clinical trials and in acquiring and in-licensing technologies and products complementary to our programs or potentially advantageous to our business. If any of our competitors succeed in obtaining approval from the FDA or other regulatory authorities for their products sooner than we do or for products that are more effective or less costly than ours, our commercial opportunity could be significantly reduced.

In order to effectively compete, we will have to make substantial investments in development, testing, manufacturing and sales and marketing or partner with one or more established companies. We may not be successful in gaining significant market share for any vaccine. Our technologies and vaccines also may be rendered obsolete or non-competitive as a result of products introduced by our competitors to the marketplace more rapidly and at a lower cost.

There is significant competition in the development of a vaccine against COVID-19, influenza, and RSV and we may never see returns on the significant resources we are devoting to our vaccine candidates.

We may be unable to produce a successful COVID-19 vaccine, and establish a competitive market share for our vaccine before the COVID-19 outbreak is contained or significantly diminished. A large number of vaccine manufacturers, academic institutions and other organizations have developed COVID-19 vaccines or are developing COVID-19 vaccine candidates. In particular, Moderna, Pfizer/BioNTech, and Johnson & Johnson have received emergency use authorizations for their COVID-19 vaccines in the U.S. and other countries, and many other companies, including AstraZeneca, Sinovac Biotech, Sinopharm, and Inovio are in various stages of developing and obtaining marketing authorization for COVID-19 vaccine candidates. Despite funding provided to us to date, many of our competitors pursuing vaccine candidates have significantly greater product candidate development, manufacturing and marketing resources than we do. Larger

pharmaceutical and biotechnology companies have extensive experience in clinical testing and obtaining regulatory approval for their products and may have the resources to heavily invest to accelerate discovery and development of their vaccine candidates. The success of our COVID-19 vaccine will depend, in part, on its relative safety, efficacy (including against emerging variant strains), side effect profile, convenience, and cost. COVID-19 vaccines approved prior to our vaccine satisfy a portion of the demand for initial vaccinations, and we no longer have access to that opportunity. In addition, COVID-19 vaccines approved prior to our vaccine may develop broad market acceptance that we are challenged to overcome. For example, in the U.S. the FDA amended the Pfizer-BioNTech EUA on September 22, 2021, and the Moderna EUA and Johnson & Johnson EUA on October 20, 2021, to authorize the use of a single booster dose for certain populations after completion of primary vaccination with any FDA-authorized or approved COVID-19 vaccine. The FDA then amended both of these Pfizer-BioNTech EUA and the Moderna EUA again on November 19, 2021, to authorize the use of such a single booster dose for all patients 18 years and older. On December 9, 2021, the FDA amended only the Pfizer-BioNTech EUA to authorize the use of the single booster dose for all patients 16 years and older. On January 3, 2022, the FDA further amended the Pfizer-BioNTech EUA again to authorize the use of the single booster dose for all patients 12 years and older and third pediatric doses for 5–11-year-old solid organ transplant patients or patients with a similar level of immunocompromise. Furthermore, if any competitors are successful in producing a more efficacious vaccine or other treatment for COVID-19 (including against emerging variant strains), or if any competitors are able to manufacture and distribute any such vaccines or treatments with greater efficiency there may be a diversion of potential governmental and other funding away from us and toward such other parties.

We are allocating significant financial and personnel resources to the development of NVX-CoV2373, which may cause delays in or otherwise negatively impact our other development programs. Our business could be negatively impacted by our allocation of significant resources to combating a global health threat that is unpredictable or against which our vaccine, if commercialized, may ultimately prove unsuccessful or unprofitable.

Many seasonal influenza vaccines are currently approved and marketed. Competition in the sale of these seasonal influenza vaccines is intense. Therefore, newly developed and approved products must be differentiated from existing vaccines in order to have commercial success. In order to show differentiation in the seasonal influenza market, a product may need to be more efficacious, particularly in older adults, and/or be less expensive or quicker to manufacture. Many competitors are working on new products and new generations of current products, intended to be more efficacious than those currently marketed. Our nanoparticle seasonal influenza vaccine candidate may not prove to be more efficacious than current products or products under development by our competitors. Further, our in-house or third-party manufacturing arrangements may not provide enough savings of time or money to provide the required differentiation for commercial success.

We are also aware that there are multiple companies with active RSV vaccine programs at various stages of development. Thus, while there is no RSV vaccine currently on the market, there is likely to be significant and consistent competition as these active programs mature. Different RSV vaccines may work better for different segments of the population, so it may be difficult for a single RSV vaccine manufacturer to provide vaccines that are marketable to multiple population segments. Geographic markets are also likely to vary significantly, which may make it difficult to market a single RSV vaccine worldwide. Even if a manufacturer brings an RSV vaccine to license, it is likely that competitors will continue to work on new products that could be more efficacious and/or less expensive. Our RSV vaccine candidate may not be as far along in development as other active RSV vaccine programs about which we are not aware, nor as efficacious as products under development by competing companies.

Many seasonal influenza vaccines are currently approved and marketed. Competition in the sale of these seasonal influenza vaccines is intense.

Risks Related to provide the required differentiation for commercial success.

We believe that there are at least two EBOV vaccine candidates currently being tested in late stage clinical trials: one by GlaxoSmithKline in collaboration with the U.S. National Institute of AllergyRegulatory and Infectious Diseases, and the other by a collaboration of NewLink Genetics, Merck Vaccines USA and the Public Health Agency of Canada. Additional vaccine candidates also are being tested, although in earlier stage clinical trials. Vaccine candidates against EBOV have been in development for more than a decade by large pharmaceutical companies, smaller biotech companies, government agencies and academic labs worldwide, and with the high visibility of the recent West Africa epidemic, development activities are likely to continue and potentially increase.

Regardless of the disease, smaller or early-stage companies and research institutions also may prove to be significant competitors, particularly through collaborative arrangements with large and established pharmaceutical companies. As these companies develop their technologies, they may develop proprietary positions, which may prevent or limit our product development and commercialization efforts. We will also face competition from these parties in recruiting and retaining qualified scientific and management personnel, establishing clinical trial sites and participant registration for clinical trials and in acquiring and in-licensing technologies and products complementary to our programs or potentially advantageous to our business. If any of our competitors succeed in obtaining approval from the FDA or other regulatory authorities for their products sooner than we do or for products that are more effective or less costly than ours, our commercial opportunity could be significantly reduced.

In order to effectively compete, we will have to make substantial investments in development, testing, manufacturing and sales and marketing or partner with one or more established companies. We may not be successful in gaining significant market share for any vaccine. Our technologies and vaccines also may be rendered obsolete or non-competitive as a result of products introduced by our competitors to the marketplace more rapidly and at a lower cost.

Compliance Matters

If we are unable to attract or retain key management or other personnel, our business, operating results and financial condition could be materially adversely affected.

We depend on our senior executive officers, as well as key scientific and other personnel. The loss of these individuals could harm our business and significantly delay or prevent the achievement of research, development or business objectives. Turnover in key executive positions resulting in lack of management continuity and long-term history with our Company could result in operational and administrative inefficiencies and added costs.

We may not be able to attract qualified individuals for key positions on terms acceptable to us. Competition for qualified employees is intense among pharmaceutical and biotechnology companies, and the loss of qualified employees, or an inability to attract, retain and motivate additional highly skilled employees could hinder our ability to complete clinical trials successfully and develop marketable products.

We also rely from time to time on outside advisors who assist us in formulating our research and development and clinical strategy. We may not be able to attract and retain these individuals on acceptable terms, which could delay our development efforts.

We may have product liability exposure.

The administration of drugs or vaccines to humans, whether in clinical trials or after marketing approval, can result in product liability claims. We maintain product liability insurance coverage in the total amount of $20 million aggregate for all claims arising from the use of products in clinical trials prior to FDA approval. Coverage is relatively expensive, and the market pricing fluctuates significantly. Therefore, we may not be able to maintain insurance at a reasonable cost. We may not be able to maintain our existing insurance coverage or obtain coverage for the use of our other products in the future. This insurance coverage and our resources may not be sufficient to satisfy all liabilities that result from product liability claims. A successful claim may prevent us from obtaining adequate product liability insurance in the future on commercially desirable items, if at all. Even if a claim is not successful, defending such a claim would be time-consuming and expensive, may damage our reputation in the marketplace and would likely divert management’s attention.

Regardless of merit or eventual outcome, liability claims may result in:

·decreased demand for our products;
·impairment of our business reputation;
·withdrawal of clinical trial participants;
·costs of related litigation;
·substantial monetary awards to participant or other claimants;
·loss of revenue; and
·inability to commercialize our vaccine candidates.

We may not be able to win government, academic institution or non-profit contracts or grants.

From time to time, we may apply for contracts or grants from government agencies, academic institutions, and non-profit organizations. Such contracts or grants can be highly attractive because they provide capital to fund the ongoing development of our technologies and vaccine candidates without diluting our stockholders. However, there is often significant competition for these contracts or grants. Entities offering contracts or grants may have requirements to apply for or to otherwise be eligible to receive certain contracts or grants that our competitors may be able to satisfy that we cannot. In addition, such entities may make arbitrary decisions as to whether to offer contracts or make grants, to whom the contracts or grants will be awarded and the size of the contracts or grants to each awardee. Even if we are able to satisfy the award requirements, we may not be a successful awardee. Therefore, we may not be able to win any contracts or grants in a timely manner, if at all.

19

Raising additional capital by issuing securities or through collaboration and licensing arrangements may cause dilution to existing stockholders or require us to relinquish rights to our technologies or vaccine candidates.

If we are unable to partner with a third-party to advance the development of one or more of our vaccine candidates, we will need to raise money through additional debt or equity financings. To the extent that we raise additional capital by issuing equity securities, our stockholders will experience immediate dilution, which may be significant. There is also a risk that such equity issuances may cause an ownership change under the Internal Revenue Code of 1986, as amended, and similar state provisions, thus limiting our ability to use our net operating loss carryforwards and credits. To the extent that we raise additional capital through licensing arrangements or arrangements with collaborative partners, we may be required to relinquish, on terms that may not be favorable to us, rights to some of our technologies or vaccine candidates that we would otherwise seek to develop or commercialize ourselves. In addition, current economic conditions may also negatively affect the desire or ability of potential collaborators to enter into transactions with us. They may also have to delay or cancel research and development projects or reduce their overall budgets.

Our business may be adversely affected if we do not successfully execute our business development initiatives.

We anticipate growing through both internal development projects, as well as external opportunities, which include the acquisition, partnering and in-licensing of products, technologies and companies or the entry into strategic alliances and collaborations. The availability of high quality opportunities is limited, and we may fail to identify candidates that we and our stockholders consider suitable or complete transactions on terms that prove advantageous. In order to pursue such opportunities, we may require significant additional financing, which may not be available to us on favorable terms, if at all. Even if we are able to successfully identify and complete acquisitions, like our business combination with Novavax AB, we may not be able to integrate the assets or take full advantage of the opportunities and, consequently, may not realize the benefits that we expect.

To effectively manage our current and future potential growth, we will need to continue to enhance our operational, financial and management processes and to effectively expand, train and manage our employee base. Supporting our growth initiatives will require significant expenditures and management resources, including investments in research and development, manufacturing and other areas of our business. If we do not successfully manage our growth and do not successfully execute our growth initiatives, then our business and financial results may be adversely impacted, and we may incur asset impairment or restructuring charges.

Litigation could have a material adverse impact on our results of operation and financial condition.

In addition to intellectual property litigation, from time to time, we may be subject to other litigation. Regardless of the merits of any claims that may be brought against us, litigation could result in a diversion of management’s attention and resources and we may be required to incur significant expenses defending against these claims. If we are unable to prevail in litigation, we could incur substantial liabilities. Where we can make a reasonable estimate of the liability relating to pending litigation and determine that it is probable, we record a related liability. As additional information becomes available, we assess the potential liability and revise estimates as appropriate. However, because of uncertainties relating to litigation, the amount of our estimates could be wrong.

Security breaches and other disruptions could compromise our information and expose us to liability, which would cause our business and reputation to suffer.

In the ordinary course of our business, we collect and store sensitive data, including intellectual property, our proprietary business information and data about our clinical participants, suppliers, and business partners and personally identifiable information. The secure maintenance of this information is critical to our operations and business strategy. Some of this information could be an attractive target of criminal attack by malicious third parties with a wide range of motives and expertise, including organized criminal groups, “hactivists,” patient groups, disgruntled current or former employees and others. Hacker attacks are of ever-increasing levels of sophistication, and despite our security measures, our information technology and infrastructure may be vulnerable to such attacks or may be breached due to employee error or malfeasance. Any such breach could compromise our networks and the information stored there could be accessed, publicly disclosed, lost or stolen. Furthermore, if our systems become compromised, we may not promptly discover the intrusion. Like other companies in our industry, we have experienced attacks to our data and systems, including malware and computer viruses. Attacks could have a material impact on our business, operations or financial results. Any access, disclosure or other loss of information could result in legal claims or proceedings, liability under laws that protect the privacy of personal information, disrupt our operations, and damage our reputation, which could adversely affect our business.

PRODUCT DEVELOPMENT RISKS

Because our vaccine product development efforts depend on new and rapidly evolving technologies, we cannot be certain that our efforts will be successful.

Our vaccine development efforts depend on new, rapidly evolving technologies and on the marketability and profitability of our products. Our development efforts and, if those are successful, commercialization of our vaccines could fail for a variety of reasons, and include the possibility that:

·our recombinant nanoparticle vaccine technologies, any or all of the products based on such technologies or our proprietary manufacturing process will be ineffective or unsafe, or otherwise fail to receive necessary regulatory clearances or commercial viability;
·we are unable to scale-up our manufacturing capabilities in a cost-effective manner;
·the products, if safe and effective, will be difficult to manufacture on a large-scale or uneconomical to market;
·our manufacturing facility will fail to continue to pass regulatory inspections;
·proprietary rights of third-parties will prevent us or our collaborators from exploiting technologies, and manufacturing or marketing products; and
·third-party competitors will gain greater market share due to superior products or marketing capabilities.

We have not completed the development of vaccine products and we may not succeed in obtaining the FDA licensure or foreign regulatory approvals necessary to sell suchour vaccine products.

candidates.


The development, manufacture and marketing of our pharmaceutical and biological products are subject to government regulation inby the U.S. FDA and regulatory authorities in other countries,jurisdictions, including the European Medicines Agency (EMA), the Czech Republic’s State Institute for Drug Control (SUKL) with respect to our manufacturing facility in the Czech Republic and the Swedish Medical Products Agency (Läkemedelsverket, LV) with respect to our adjuvant product being developed in Sweden.Sweden, as well as other country authorities into which active pharmaceutical ingredients and excipients are imported and/or manufactured by us or our sub-contracted manufacturers. In the U.S. and most foreign countries, we must complete rigorous preclinical testing and extensive clinical trials that demonstrate the safety and efficacy of a product in order to apply for regulatory approval to market the product. Additionally, we must demonstrate that our manufacturing facilities, processes and controls are adequate with respect to such product to assure safety, purity and potency and comply with applicable good manufacturing practice requirements. None of our vaccine candidates havehas yet gained regulatory approval in the U.S., although NVX-CoV2373 has received provisional registration, conditional marketing authorization or elsewhere.emergency

use authorization in certain other jurisdictions. We also have vaccine candidates in clinical trials and preclinical laboratory or animal studies.


Our products might fail to meet their primary endpoints in clinical trials, meaning that we will not have the clinical data required to support regulatory obligations.

The steps generally required by the FDA before our proposed investigational products may be marketed in the U.S. include:

·performance of preclinical (animal and laboratory) tests;
·submissions to the FDA of an IND, which must become effective before clinical trials may commence;
·performance of adequate and well controlled clinical trials to establish the safety and efficacy of the investigational product in the intended target population;
·performance of a consistent and reproducible manufacturing process intended for commercial use, including appropriate manufacturing data and regulatory inspections;
·submission to the FDA of a BLA or a NDA; and
·FDA approval of the BLA or NDA before any commercial sale or shipment of the product.

The


performance of preclinical (animal and laboratory) tests;

submission to the FDA of an IND, which must become effective before clinical trials may commence;

performance of adequate and well controlled clinical trials to establish the safety and efficacy of the investigational product in the intended target population;

performance of a consistent and reproducible manufacturing process at commercial scale capable of passing FDA inspection;

submission to the FDA of a BLA or a NDA; and

FDA approval of the BLA or NDA before any commercial sale or shipment of the product.

Clinical trials that we undertake in other countries will be subject to similar or equivalent processes and requirements, In Europe, as well as an authorization for the trial itself, it is necessary to obtain the consent of a local ethics committee for each trial site and to provide for publication specific information about the trial and its outcome. If endpoints are not met, this information will be made publicly available and could be damaging to the reputation of the Company.

These processes are expensive and can take many years to complete, and we may not be able to demonstrate the safety, purity, potency and efficacy of our vaccine candidates to the satisfaction of regulatory authorities. The start of clinical trials can be delayed or take longer than anticipated for many and varied reasons, many of which are out of our control. Safety concerns may emerge that could lengthen the ongoing clinical trials or require additional clinical trials to be conducted. Promising results in early clinical trials may not be replicated in subsequent clinical trials. Regulatory authorities may also require additional testing, and we may be required to demonstrate that our proposed products represent an improved form of treatment over existing therapies, which we may be unable to do without conducting further clinical trials. Moreover, if the FDA or a foreign regulatory bodyauthority grants regulatory approval of a product, the approval may be limited to specific indications or limited with respect to its distribution. Expanded or additional indications for approved products may not be approved, which could limit our revenue. Foreign regulatory authorities may apply similar limitations or may refuse to grant any approval. Consequently, even if we believe that preclinical and clinical data are sufficient to support regulatory approval for our vaccine candidates, the FDA and foreign regulatory authorities ultimately may not ultimately grant approval for commercial sale in any jurisdiction.their applicable jurisdiction, or may impose regulatory requirements that make further pursuit of approval uneconomical in one or more jurisdictions. If our vaccine candidates are not approved, our ability to generate revenue will be limited, and our business will be adversely affected.

21

If we are unable to manufacture our vaccines in sufficient quantities, at sufficient yields or are unable to obtain regulatory approvals for a manufacturing facility for our vaccines, we may experience delays in product development, clinical trials, regulatory approval and commercial distribution.

Completion of our clinical trials and commercialization of our vaccine candidates require access to, or development of, facilities to manufacture our vaccine candidates at sufficient yields and at commercial-scale. We have limited experience manufacturing any of our vaccine candidates in the volumes that will be necessary to support large-scale clinical trials or commercial sales. Efforts to establish these capabilities may not meet initial expectations as to scheduling, scale-up, reproducibility, yield, purity, cost, potency or quality.

Manufacturing our vaccine candidates involves a complicated process with which we have limited experience. If we are unable to manufacture our vaccine candidates in clinical quantities or, when necessary, in commercial quantities and at sufficient yields, then we must rely on third-parties. Other third-party manufacturers must also receive FDA approval before they can produce clinical material or commercial products. Our vaccines may be in competition with other products for access to these facilities and may be subject to delays in manufacture if third-parties give other products greater priority. We may not be able to enter into any necessary third-party manufacturing arrangements on acceptable terms, or on a timely basis. In addition, we have to enter into technical transfer agreements and share our know-how with the third-party manufacturers, which can be time-consuming and may result in delays.

Like influenza, a licensed RSV vaccine would likely be seasonal in nature. If a seasonal vaccine is not available early enough in the season, we would likely have difficulty selling that vaccine. For these reasons, any delay in the delivery of a seasonal vaccine could result in lower sales volumes, lower sale prices, or no sales. Strains of the seasonal influenza change annually, which means that inventory of seasonal vaccine cannot be sold during a subsequent influenza season. We believe that while RSV strains may also change annually, our RSV F Vaccine is directed at highly-conserved epitopes that are unlikely to change annually, although that has not yet been definitively demonstrated. Any delay in the manufacture of our vaccines could adversely affect our ability to sell the vaccines.

Our reliance on contract manufacturers may adversely affect our operations or result in unforeseen delays or other problems beyond our control. Because of contractual restraints and the limited number of third-party manufacturers with the expertise, required regulatory approvals and facilities to manufacture our bulk vaccines on a commercial-scale, replacement of a manufacturer may be expensive and time-consuming and may cause interruptions in the production of our vaccine. A third-party manufacturer may also encounter difficulties in production. These problems may include:

·difficulties with production costs, scale up and yields;
·availability of raw materials and supplies;
·quality control and assurance;
·shortages of qualified personnel;
·compliance with strictly enforced federal, state and foreign regulations that vary in each country where products might be sold; and
·lack of capital funding.

As a result, any delay or interruption could have a material adverse effect on our business, financial condition, results of operations and cash flows.

We must identify vaccines for development with our technologies and establish successful third-party relationships.

The near and long-term viability of our vaccine candidates will depend in part on our ability to successfully establish new strategic collaborations with pharmaceutical and biotechnology companies, non-profit organizations and government agencies. Establishing strategic collaborations and obtaining government funding is difficult and time-consuming. Potential collaborators may reject collaborations based upon their assessment of our financial, regulatory or intellectual property position or based on their internal pipeline; government agencies may reject contract or grant applications based on their assessment of public need, the public interest, our products’ ability to address these areas, or other reasons beyond our expectations or control. If we fail to establish a sufficient number of collaborations or government relationships on acceptable terms, we may not be able to commercialize our vaccine candidates or generate sufficient revenue to fund further research and development efforts.

22

Even if we establish new collaborations or obtain government funding, these relationships may never result in the successful development or commercialization of any vaccine candidates for several reasons, including the fact that:

·we may not have the ability to control the activities of our partners and cannot provide assurance that they will fulfill their obligations to us, including with respect to the license, development and commercialization of vaccine candidates, in a timely manner or at all;
·such partners may not devote sufficient resources to our vaccine candidates or properly maintain or defend our intellectual property rights;
·any failure on the part of our partners to perform or satisfy their obligations to us could lead to delays in the development or commercialization of our vaccine candidates and affect our ability to realize product revenue; and
·disagreements, including disputes over the ownership of technology developed with such collaborators, could result in litigation, which would be time consuming and expensive, and may delay or terminate research and development efforts, regulatory approvals and commercialization activities.

Our collaborators will be subject to the same regulatory approval of their manufacturing facility and process as us. Before we could begin commercial manufacturing of any of our vaccine candidates, we and our collaborators must pass a pre-approval inspection before FDA approval and comply with the FDA’s GMP regulations. If our collaborators fail to comply with these requirements, our vaccine candidates would not be approved. If our collaborators fail to comply with these requirements after approval, we could be subject to possible regulatory action and may be limited in the jurisdictions in which we are permitted to sell our products.

If we or our collaborators fail to maintain our existing agreements or in the event we fail to establish agreements as necessary, we could be required to undertake research, development, manufacturing and commercialization activities solely at our own expense. These activities would significantly increase our capital requirements and, given our lack of sales, marketing and distribution capabilities, significantly delay the commercialization of our vaccine candidates.

Because we depend on third-parties to conduct some of our laboratory testing, clinical trials, and manufacturing, we may encounter delays in or lose some control over our efforts to develop products.

We are dependent on third-party research organizations to conduct some of our laboratory testing, clinical trials and manufacturing activities. If we are unable to obtain any necessary services on acceptable terms, we may not complete our product development efforts in a timely manner. We may lose some control over these activities and become too dependent upon these parties. These third-parties may not complete testing or manufacturing activities on schedule, within budget, or when we request. We may not be able to secure and maintain suitable research organizations to conduct our laboratory testing, clinical trials and manufacturing activities. We have not manufactured any of our vaccine candidates at a commercial level and may need to identify additional third-party manufacturers to scale-up and manufacture our products.

We are responsible for confirming that each of our clinical trials is conducted in accordance with its general investigational plan and protocol. Moreover, the FDA and foreign regulatory agencies require us to comply with regulations and standards, commonly referred to as good clinical practices, for conducting, recording and reporting the results of clinical trials to assure that data and reported results are credible and accurate and that the clinical trial participants are adequately protected. The FDA and foreign regulatory agencies also require us to comply with good manufacturing practices. Our reliance on third-parties does not relieve us of these responsibilities and requirements. These third-parties may not successfully carry out their contractual duties or regulatory obligations or meet expected deadlines. In addition, these third-parties may need to be replaced or the quality or accuracy of the data they obtain may be compromised or the product they manufacture may be contaminated due to the failure to adhere to our clinical and manufacturing protocols, regulatory requirements or for other reasons. In any such event, our preclinical development activities or clinical trials may be extended, delayed, suspended or terminated, and we may not be able to obtain regulatory approval of, or commercially manufacture, our vaccine candidates.

23

Even if licensed to market, our vaccine products may not be initially or ever profitable.

Whether Novavax makes a profit from the sale of its vaccine products is dependent on a number of variables, including the costs we incur manufacturing, testing and releasing, packaging and shipping such vaccine product. The Grant Agreement with BMGF necessitates that we commit to a specific amount of sales in certain specified middle and lower income countries, which may impact our ability to make profits. In addition, we have not yet determined pricing for our vaccine products, which is a complicated undertaking that necessitates both regulatory agency and payor support. We cannot predict when, if at all, our approved vaccine products will be profitable to the Company.

Our collaborations may not be profitable.

We formed CPLB with Cadila in India, but we cannot predict when, if at all, this relationship will lead to additional approved products, sales, or otherwise provide revenue to the Company or become profitable.

We have limited marketing capabilities, and if we are unable to enter into collaborations with marketing partners or develop our own sales and marketing capability, we may not be successful in commercializing any approved products.

Although we have initiated preliminary activities in anticipation of commercialization of our vaccine candidates, we currently have no dedicated sales, marketing or distribution capabilities. As a result, we will depend on collaborations with third-parties that have established distribution systems and sales forces. To the extent that we enter into co-promotion or other licensing arrangements, our revenue will depend upon the efforts of third-parties, over which we may have little or no control. If we are unable to reach and maintain agreements with one or more pharmaceutical companies or collaborators, we may be required to market our products directly. Developing a marketing and sales force is expensive and time-consuming and could delay a product launch. We may not be able to attract and retain qualified sales personnel or otherwise develop this capability.

Our vaccine candidates may never achieve market acceptance even if we obtain regulatory approvals.

Even if we receive regulatory approvals for the commercial sale of our vaccine candidates, the commercial success of these vaccine candidates will depend on, among other things, their acceptance by physicians, patients, third-party payers, such as health insurance companies and other members of the medical community, as a vaccine and cost-effective alternative to competing products. If our vaccine candidates fail to gain market acceptance, we may be unable to earn sufficient revenue to continue our business. Market acceptance of, and demand for, any product that we may develop and commercialize will depend on many factors, including:

·our ability to provide acceptable evidence of safety and efficacy;
·the prevalence and severity of adverse side effects;
·whether our vaccines are differentiated from other vaccines;
·availability, relative cost and relative efficacy of alternative and competing treatments;
·the effectiveness of our marketing and distribution strategy;
·publicity concerning our products or competing products and treatments; and
·our ability to obtain sufficient third party insurance coverage or reimbursement.

Unlike RSV, where there is no current vaccine available, there are significant challenges to market seasonal influenza vaccines. For a seasonal vaccine to be accepted in the market, it must demonstrate differentiation from other seasonal vaccines that are currently approved and marketed. This can mean that the vaccine is more effective in certain populations, such as in older adults, or cheaper and quicker to produce. There are no assurances that our influenza vaccine can be differentiated from other influenza vaccines.

If our vaccine candidates do not become widely accepted by physicians, patients, third-party payers and other members of the medical community, our business, financial condition and results of operations could be materially and adversely affected.

24

We may not be able to secure sufficient supplies of a key component of our adjuvant technology.

Because an important component of our adjuvant technology is extracted from a species of soap-bark tree (Quillaja saponaria) grown in Chile, we need long term access to quillaja extract with a consistent and sufficiently high quality. We need a secure supply of raw material, as well as back-up suppliers, or our adjuvant products may be delayed.

If reforms in the health care industry make reimbursement for our potential products less likely, the market for our potential products will be reduced, and we could lose potential sources of revenue.

Our success may depend, in part, on the extent to which reimbursement for the costs of vaccines will be available from third-party payers, such as government health administration authorities, private health insurers (including managed care plans), and other organizations. Over the past decade, the cost of health care has risen significantly, and there have been numerous proposals by legislators, regulators and third-party health care payers to curb these costs. Some of these proposals have involved limitations on the amount of reimbursement for certain products. Similar federal or state health care legislation may be adopted in the future and any products that we or our collaborators seek to commercialize may not be considered cost-effective. Adequate third-party insurance coverage may not be available for us to establish and maintain price levels that are sufficient for realization of an appropriate return on our investment in product development. Moreover, the existence or threat of cost control measures could cause our corporate collaborators to be less willing or able to pursue research and development programs related to our vaccine candidates.

REGULATORY RISKS

We may fail to obtain regulatory approval for our products on a timely basis or comply with our continuing regulatory obligations after approval is obtained.


Delays in obtaining regulatory approval can be extremely costly in terms of lost sales opportunities, loss of any potential marketing advantage of being early to market and increased clinical trial costs. For example, certain of our APAs and supply agreements may be terminated by the counterparty if we do not timely achieve requisite regulatory approval for NVX-CoV2373 in the relevant jurisdictions under such agreements. The speed with which we begin and complete ourthe preclinical studies necessary to begin clinical trials, the clinical trials themselves and our applications for marketing approval will depend on several factors, including the following:

·our ability to manufacture or obtain sufficient quantities of materials for use in necessary preclinical studies and clinical trials;
·prior regulatory agency review and approval;
·approval of the protocol and the informed consent form by the review board of the institution conducting the clinical trial;
·the rate of participant enrollment and retention, which is a function of many factors, including the size of the participant population, the proximity of participants to clinical sites, the eligibility criteria for the clinical trial and the nature of the protocol;
·negative test results or side effects experienced by clinical trial participants;
·analysis of data obtained from preclinical and clinical activities, which are susceptible to varying interpretations and which interpretations could delay, limit or prevent further studies or regulatory approval;
·the availability of skilled and experienced staff to conduct and monitor clinical trials and to prepare the appropriate regulatory applications; and
·changes in the policies of regulatory authorities for drug or vaccine approval during the period of product development.


our ability to scale-up manufacturing capability that reproducibly generates consistent yields of product with required purity,potency and quality; that such scale-up occurs on a timely basis; and that we have access to sufficient quantities of materials for use in necessary preclinical studies and clinical trials;

regulatory authority review and approval of proposed clinical trial protocols;

approval of clinical trials protocols and informed consent forms by institutional review boards responsible for overseeing the ethical conduct of the trial;

the rate of participant enrollment and retention, which is a function of many factors, including the size of the participant population, the proximity of participants to clinical sites, the eligibility criteria for the clinical trial and the nature of the protocol;

unfavorable test results or side effects experienced by clinical trial participants;

analysis of data obtained from preclinical and clinical activities, which are susceptible to varying interpretations and which interpretations could delay, limit, result in the suspension or termination of, or prevent further conduct of clinical studies or regulatory approval;

the availability of skilled and experienced staff to conduct and monitor clinical trials and to prepare the appropriate regulatory applications; and

changes in the policies of regulatory authorities for drug or vaccine approval during the period of product development.

We have limited experience in conducting and managing the preclinical studies and clinical trials necessary to obtain regulatory marketing approvals. We may not be permitted to continue or commence additional clinical trials. We also face the risk that the results of our clinical trials may be inconsistent with the results obtained in preclinical studies or clinical trials of similar products or that the results obtained in later phases of clinical trials may be inconsistent with those obtained in earlier phases. A number of companies in the biotechnology and product development industry have suffered significant setbacks in advanced clinical trials, even after experiencing promising results in early animal and human testing.

25


Regulatory agencies may require us or our collaborators to delay, restrict or discontinue clinical trials on various grounds, including a finding that the participants are being exposed to an unacceptable health risk. In addition, we or our collaborators may be unable to submit applications to regulatory agencies within the time frame we currently expect. Once submitted, applications must be approved by various regulatory agencies before we or our collaborators can commercialize the product described in the application. All statutes and regulations governing the conduct of clinical trials are subject to change in the future, which could affect the cost of such clinical trials. Any unanticipated costs or delays in our clinical trials or regulatory submissions could delay our ability to generate revenue and harm our financial condition and results of operations.


Failure to obtain regulatory approval in foreign jurisdictions would prevent us from marketing our products internationally.


We intend to have our vaccine candidates marketed outside the U.S. In furtherance of this objective, we have entered into relationshipssupply agreements with Cadila in India.various foreign governments and international distribution agreements with commercial entities. In order to market our products in the European Union, United Kingdom, India, Asia and many other non-U.S. jurisdictions, we must obtain separate regulatory approvals and comply with numerous and varying regulatory requirements. The approval procedure varies among countries and can involve additional testing and data review. The time required to obtain foreign regulatory approval may differ from that required to obtain FDA approval. The foreign regulatory approval process may include all of the risks associated with obtaining FDA approval. WeAdditionally, regulatory authorities outside the United States might not accept data from trials conducted in other countries. Although NVX-CoV2373 has received provisional registration, conditional marketing authorization or emergency use authorization in a number of jurisdictions, we may not obtain foreign regulatory approvals in other relevant jurisdictions on a timely basis, if at all. Approval by aone regulatory agency such as the FDA, does not ensure approval by any other regulatory agencies in other foreign countries.jurisdictions. However, a failure or delay in obtaining regulatory approval in one jurisdiction may have a negative effect on the regulatory approval process in other jurisdictions, including approval by the FDA. The failure to obtain regulatory approval in foreign jurisdictions could harm our business.

Even if


44

The regulatory pathway for NVX-CoV2373 is continually evolving and may result in unexpected or unforeseen challenges.

The regulatory pathway for NVX-CoV2373 is evolving and failure by us to comply with any laws, rules and standards, some of which may not exist yet or are subject to interpretation and may be subject to change, could result in a variety of adverse consequences, including penalties, fines and delays in vaccine licensure. Efforts to comply with evolving laws, regulations and standards have resulted in, and are likely to continue to result in, increased general and administrative expenses and a diversion of management time and attention to regulatory compliance activities. For example, the rules, regulations and standards governing OWS are uncertain and may evolve as the program progresses. Such rules or standards may adversely affect our plans to develop NVX-CoV2373 and failure by us to comply with any laws, rules or standards, some of which may not exist yet or may change, could result in a range of adverse consequences, such as penalties, fines or failure to receive funding.

The speed at which multiple stakeholders are moving to create, test and approve vaccines for COVID-19 is highly unusual and may increase the risks associated with traditional vaccine development, which typically takes between eight and ten years. Given this accelerated timeline, we and regulators, such as the FDA, the EMA, and the MHRA may make decisions more rapidly than is typical. Evolving or changing plans or priorities at the FDA or other regulatory bodies to whom we wish to apply for authorization, including based on new knowledge of COVID-19 and how the disease affects the human body, and new variants of the virus, may significantly affect the regulatory pathway for NVX-CoV2373. Results from clinical testing may raise new questions and require us to redesign proposed clinical trials, including revising proposed endpoints or adding new clinical trial sites or cohorts of subjects. In addition, the FDA’s or other regulatory authorities’ analysis of clinical data may differ from our interpretation, or regulators’ requirements and expectations for vaccine authorization or approval may change over time, with the result that the FDA or other regulators may require that we conduct additional clinical trials or non-clinical studies. The evolving regulatory pathway may impede the development, commercialization and/or licensure of NVX-CoV2373.

In addition, because the path to licensure of any vaccine against COVID-19 is receivedunclear, we may have a widely used vaccine in circulation in certain countries as an investigational vaccine or a product authorized for temporary or emergency use prior to our vaccine candidates,receipt of full marketing approval. Unexpected safety issues in these circumstances could lead to significant reputational damage for Novavax and our technology platform going forward and other issues, including delays in our other programs, the need for re-design of our clinical trials and the need for significant additional financial resources.

We have conducted, continue to conduct and plan to conduct in the future, a number of clinical trials for NVX-CoV2373 at sites outside the United States and the FDA may not accept data from trials conducted in such locations.

We are currently conducting several clinical trials of NVX-CoV2373 at sites outside the U.S., including a Phase 3 trial partially in Mexico, a Phase 3 trial in the U.K., a Phase 2b trial in South Africa, a Phase 1/2 trial partially in Australia, a Phase 2/3 trial in India, and a Phase 1/2 trial in Japan. Although the FDA may accept data from clinical trials conducted outside the U.S., acceptance of these data is subject to conditions imposed by the FDA. For example, the clinical trial must be well designed and conducted and be performed by qualified investigators in accordance with ethical principles. The trial population must also adequately represent the U.S. population, and the data must be applicable to the U.S. population and U.S. medical practice in ways that the FDA deems clinically meaningful. Other regulatory authorities impose equivalent requirements for their countries. In addition, while these clinical trials are subject to the applicable local laws, where the data is to be used to support our U.S. NDA, FDA acceptance of the data will depend on its determination that the trials also complied with all applicable U.S. laws and regulations. If the FDA does not accept the data from any trial that we conduct outside the U.S., it could result in delay pending completion of our trials conducted in the U.S. or result in the need for additional trials, which would be costly and time-consuming and could delay or permanently halt our development of NVX-CoV2373.

The later discovery of previously unknown problems with a product, manufacturer or facility may result in restrictions, including withdrawal of the producta vaccine that had previously received regulatory approval in certain jurisdictions from the market.


Even ifafter a product gains regulatory approval, such approval is likely to limit the indicated uses for which it may be marketed, and the product and the manufacturer of the product will be subject to continuing regulatory review, including adverse event reporting requirements and the FDA’s general prohibitionprohibitions against promoting products for unapproved uses. Failure to comply with any post-approval requirements can, among other things, result in warning letters, product seizures, recalls, substantial fines, injunctions, suspensions or revocations of marketing authorizations or licenses, operating restrictions and criminal prosecutions. Any of thesesuch enforcement actions, any unanticipated changes in existing regulatory requirements or the adoption of new requirements, or any safety issues that arise with any approved products,
45

could adversely affect our ability to market products and generate revenue and thus adversely affect our ability to continue our business.


We also may be restricted or prohibited from marketing or manufacturing a product, even after obtaining product approval, if previously unknown problems with the product or its manufacture are subsequently discovered and wediscovered. We cannot provide assurance that newly discovered or developed safety issues will not arise following any regulatory approval. With the use of any vaccine by a wide patient population, serious adverse events may occur from time to time that did not arise in the clinical trials of the product or that initially do not appearappeared to relatebe unrelated to the vaccine itself and only ifwith the specific event occurs with some regularity over a periodcollection of time does the vaccine become suspect as having a causal relationshipsubsequent information were found to be causally related to the adverse event.product. Any such safety issues could cause us to suspend or cease marketing of our approved products, possibly subject us to substantial liabilities, and adversely affect our ability to generate revenue and our financial condition.


Our ability to produce a successful vaccine may be curtailed by one or more government actions or interventions, which may be more likely during a global health crisis such as COVID-19.

Given the significant global impact of the COVID-19 pandemic, it is possible that one or more government entities may take actions, including under the U.S. government under the Defense Production Act of 1950, as amended, that directly or indirectly have the effect of diminishing some of our rights or opportunities with respect to NVX-CoV2373, and the economic value of a COVID-19 vaccine to us could be limited. In addition, during a global health crisis, such as the COVID-19 pandemic, where the spread of a disease needs to be controlled, closed or heavily regulated national borders create challenges and delays in our development, production and distribution activities and may necessitate that we pursue strategies to develop, produce and distribute our vaccine candidates within self-contained national or international borders or with additional safety measures or checks in place, at potentially much greater expense and with longer timeframes for public distribution.

Inadequate funding for the FDA, the SEC and other regulatory authorities could hinder their ability to hire and retain key leadership and other personnel, or otherwise perform their normal functions on which the operation of our business may rely, which could negatively impact our ability to develop or commercialize new products or services, access capital markets, or otherwise operate our business.

The ability of the FDA and other regulatory authorities to review and approve new product applications is affected by a variety of factors, including government budget and funding levels, ability to hire and retain key personnel and accept the payment of user fees, and statutory, regulatory and policy changes. For example, average review times at the FDA have fluctuated in recent years as a result. In addition, government funding of the SEC and other government agencies on which our operations may rely, including those that fund research and development activities, is subject to the political process, which is inherently fluid and unpredictable.

Disruptions at the FDA and other agencies may also slow the time necessary for new drugs to be reviewed and approved by necessary government agencies, which would adversely affect our business. For example, over the last several years, the U.S. government has shut down several times and certain regulatory agencies, such as the FDA and the SEC, have had to furlough employees and stop or slow the pace of critical activities. Equally, the move of the EMA to the Netherlands from London caused a significant loss of experienced staff and the UK’s MHRA’s loss of funding from the E.U. has caused a loss of funding and consequently of staff. If a prolonged government shutdown or slowdown of the relevant regulatory authority occurs, it could significantly impact the ability of that Authority to timely review and process our regulatory submissions, which could have a material adverse effect on our business. Further, in our operations as a public company, future government shutdowns could impact our ability to access the public markets and obtain necessary capital in order to properly capitalize and continue our operations.

Fast Track Designation by the FDA, the issue of conditional marketing authorizations by the EMA or MHRA, or other regulatory acceleration options may not actually lead to a faster development or regulatory review or approval process and does not assure approval.

If a drug is intended for the treatment of a serious or life-threatening condition and the drug demonstrates the potential to address an unmet medical need for this condition, the drug sponsor may apply for FDA Fast Track Designation or similar fast track processes with other regulatory agencies, such as conditional marketing authorizations from the EMA or MHRA. However, Fast Track Designation or conditional authorizations do not ensure that the drug sponsor will receive marketing approval or that approval will be granted within any particular timeframe. The FDA granted Fast Track Designation for NVX-CoV2373 in November 2020 and for NanoFlu, our recombinant quadrivalent seasonal influenza vaccine candidate, in January 2020. We may also seek Fast Track Designation for more of our other vaccine candidates. If we do seek Fast Track Designation for our other vaccine candidates, we may not receive it, and even if we receive Fast Track
46

Designation, we may not experience a faster development process, review or approval compared to conventional FDA procedures. In addition, the FDA may withdraw Fast Track designation if it believes that the designation is no longer supported by data from our clinical development program. Fast Track Designation alone does not guarantee qualification for the FDA’s priority review procedures.

Obtaining a Fast Track Designation does not change the standards for product approval, but may expedite the development or approval process. Even though the FDA has granted such designation for NVX-CoV2373 and NanoFlu, it may not actually result in faster clinical development or regulatory review or approval. Furthermore, such a designation does not increase the likelihood that NVX-CoV2373 or NanoFlu will receive marketing approval in the U.S.

Because we are subject to environmental, health and safety laws, we may be unable to conduct our business in the most advantageous manner.


We are subject to various laws and regulations relating to safe working conditions, laboratory and manufacturing practices, the experimental use of animals, emissions and wastewater discharges, and the use and disposal of hazardous or potentially hazardous substances used in connection with our research, including infectious disease agents. We also cannot accurately predict the extent of regulations that might result from any future legislative or administrative action. Any of these laws or regulations could cause us to incur additional expense or restrict our operations.

26


Our facilities in Maryland are subject to various local, state and federal laws and regulations relating to safe working conditions, laboratory and manufacturing practices, the experimental use of animals and the use and disposal of hazardous or potentially hazardous substances, including chemicals, microorganisms and various hazardous compounds used in connection with our research and development activities. In the U.S., these laws include the Occupational Safety and Health Act, the Toxic Test Substances Control Act and the Resource Conservation and Recovery Act. Similar national and local regulations govern our facilityfacilities in Sweden.Sweden and the Czech Republic. We cannot eliminate the risk of accidental contamination or discharge or injury from these materials. Federal, state and local laws and regulations govern the use, manufacture, storage, handling and disposal of these materials. We could be subject to civil damages in the event of an improper or unauthorized release of, or exposure of individuals to, these hazardous materials. In addition, claimants may sue us for injury or contamination that results from our use or the use by third-partiesthird parties of these materials, and our liability may exceed our total assets. Compliance with environmental laws and regulations may be expensive, and current or future environmental regulations may impair our research, development or production efforts.


Although we have general liability insurance, these policies contain exclusions from insurance against claims arising from pollution from chemicals or pollution from conditions arising from our operations. Our collaborators are working with these types of hazardous materials in connection with our collaborations. In the event of a lawsuit or investigation, we could be held responsible for any injury we or our collaborators cause to persons or property by exposure to, or release of, any hazardous materials. However, we believe that we are currently in compliance with all material applicable environmental and occupational health and safety regulations.

Even if we successfully commercialize any of our vaccine candidates, either alone or in collaboration, we face uncertainty with respect to pricing, third-party reimbursement and healthcare reform, all of which could adversely affect any commercial success of our vaccine candidates.

Our ability to collect revenue from the commercial sale of our vaccines may depend on our ability, and that of any current or potential future collaboration partners or customers, to obtain adequate levels of approval, coverage and reimbursement for such products from third-party payers such as:

·government health administration authorities such as the Advisory Committee for Immunization Practices of the Center for Disease Control and Prevention (“CDC”);
·private health insurers;
·managed care organizations;
·pharmacy benefit management companies; and
·other healthcare related organizations.

Third-party payers are increasingly challenging the prices charged for medical products and may deny coverage or offer inadequate levels of reimbursement if they determine that a prescribed product has not received appropriate clearances from the FDA, or foreign equivalent, or other government regulators; is not used in accordance with cost-effective treatment methods as determined by the third-party payer; or is experimental, unnecessary or inappropriate. Prices could also be driven down by managed care organizations that control or significantly influence utilization of healthcare products.

In both the U.S. and some foreign jurisdictions, there have been a number of legislative and regulatory proposals and initiatives to change the health care system in ways that could affect our ability to sell vaccines. Some of these proposed and implemented reforms could result in reduced reimbursement rates for medical products, and while we have no current vaccines available for commercial sale, the impact of such reform could nevertheless adversely affect our business strategy, operations and financial results. For example, the Healthcare Reform Act contained several cost containment measures that could adversely affect our future revenue, including, for example, increased drug rebates under Medicaid for brand name prescription drugs, extension of Medicaid rebates to Medicaid managed care organizations, and extension of so-called 340B discounted pricing on pharmaceuticals sold to certain healthcare providers. Additional provisions of the healthcare reform laws that may negatively affect our future revenue and prospects for profitability include the assessment of an annual fee based on our proportionate share of sales of brand name prescription drugs to certain government programs, including Medicare and Medicaid, as well as mandatory discounts on drugs (including vaccines) sold to certain Medicare Part D beneficiaries in the coverage gap (the so-called “donut hole”). Other aspects of healthcare reform, such as expanded government enforcement authority and heightened standards that could increase compliance-related costs, could also affect our business. In addition, we face uncertainties because there are ongoing federal legislative and administrative efforts to repeal, substantially modify or invalidate some or all of the provisions of the Healthcare Reform Act. For example, in 2017, the President announced that his administration will withhold the cost-sharing subsidies paid to health insurance exchange plans serving low-income enrollees. Tax reform legislation was also enacted at the end of 2017 that includes provisions that will affect healthcare insurance coverage and payment, such as the elimination of the tax penalty for individuals who do not maintain sufficient health insurance coverage beginning in 2019 (the so-called “individual mandate”). The Bipartisan Budget Act of 2018 contained various provisions that affect coverage and reimbursement of drugs, including an increase in the mandatory discounts on pharmaceuticals sold to certain Medicare Part D beneficiaries in the coverage gap starting in 2019. We cannot predict the ultimate content, timing or effect of any healthcare reform legislation or the impact of potential legislation on us.

If

For our product candidates, obtain marketing approval, we will be subject to additional healthcare laws and our failure to comply with those laws could have a material adverse effect on our results of operations and financial conditions.


Within the U.S. (and within foreign countries), if we obtain approval for any of our product candidates and begin commercializing them, our operations may be directly, or indirectly through our arrangements with third-party payors and customers, subject to additional healthcare regulation and enforcement by the federal and state governments. In additiongovernments (or the regulatory bodies or governments of foreign countries), which may constrain the business or financial arrangements and relationships through which we sell, market and distribute our products. These laws and regulations may restrict or prohibit a wide range of pricing, discounting, marketing and promotion, structuring and commission(s), certain customer incentive programs and other business arrangements generally. Activities subject to these laws also involve the improper use of information obtained in the course of patient recruitment for clinical trials. The applicable U.S. federal and state healthcare laws mentioned above, theand regulations (which may be comparable to foreign laws existing in foreign countries) that may affect our ability to operate include:

·the Food, Drug and Cosmetic Act, which among other things, strictly regulates drug product marketing and promotion and prohibits manufacturers from marketing such products for off-label use;
·the federal anti-kickback law, which prohibits, among other things, persons from soliciting, receiving or providing remuneration, directly or indirectly, to induce the referral for an item or service or the purchasing or ordering of a good or service, for which payment may be made under federal healthcare programs such as Medicare and Medicaid;
·federal false claims laws which prohibit, among other things, individuals or entities from knowingly presenting, or causing to be presented, information or claims for payment from Medicare, Medicaid, or other third-party payors that are false or fraudulent;
·federal laws that require pharmaceutical manufacturers to report certain calculated product prices to the government or provide certain discounts or rebates to government authorities or private entities, often as a condition of reimbursement under government healthcare programs;
·the so-called “federal sunshine” law (also known as “open payments”) which requires pharmaceutical and medical device manufacturers to report certain financial interactions to the federal government for re-disclosure to the public;
·the federal law known as HIPAA, which, in addition to privacy protections applicable to healthcare providers and other entities, prohibits executing a scheme to defraud any healthcare benefit program or making false statements relating to healthcare matters;
·state law equivalents of the above federal laws, such as anti-kickback and false claims laws which may apply to items or services reimbursed by any third-party payor, including commercial insurers, and state gift ban and transparency laws, many of which state laws differ from each other in significant ways and often are not preempted by federal laws, thus complicating compliance efforts; and
·state laws restricting interactions with healthcare providers and other members of the healthcare community or requiring pharmaceutical manufacturers to implement certain compliance standards.


the Federal Food, Drug and Cosmetic Act, which among other things, strictly regulates drug product marketing and promotion and prohibits manufacturers from marketing such products for unapproved uses;

the federal Anti-Kickback Statute, which prohibits, among other things, persons from knowingly and willfully soliciting, receiving or providing remuneration, directly or indirectly, to induce the referral for an item or service or
47

the purchasing or ordering of a good or service, for which payment may be made under federal healthcare programs such as Medicare and Medicaid;

federal false claims laws, including the False Claims Act (“FCA”), which prohibit, among other things, individuals or entities from knowingly presenting, or causing to be presented, information or claims for payment from Medicare, Medicaid, or other third-party payers that are false or fraudulent;

manufacturers can be held liable under the FCA even when they do not submit claims directly to government payors if they are deemed to “cause” the submission of false or fraudulent claims; the FCA also permits a private individual acting as whistleblower to bring actions on behalf of the federal government alleging violations of the FCA and to share in any monetary recovery;

federal laws that require pharmaceutical manufacturers to report certain calculated product prices to the government or provide certain discounts or rebates to government authorities or private entities, often as a condition of reimbursement under government healthcare programs;

the federal Physician Payment Sunshine Act and its implementing regulations, which require manufacturers of drugs, devices, biologicals, and medical supplies for which payment is available under Medicare, Medicaid or the Children’s Health Insurance Program (with certain exceptions) to report annually to the DHHS information related to payments or other transfers of value made to physicians (defined to include doctors, dentists, optometrists and chiropractors) and teaching hospitals, as well as ownership and investment interests held by physicians and their immediate family members; effective January 1, 2022, these reporting obligations extend to include transfers of value made to certain non-physician providers such as physician assistants and nurse practitioners; similar reporting requirements have also been enacted on the state level in the United States, and an increasing number of countries worldwide either have adopted or are considering similar laws requiring disclosure of interactions with health care professionals;

the federal law known as HIPAA, which, in addition to privacy protections applicable to healthcare providers and other entities, prohibits executing a scheme to defraud any healthcare benefit program or making false statements relating to healthcare matters;

federal consumer protection and unfair competition laws, which broadly regulate marketplace activities and activities that potentially harm consumers;

state law equivalents of the above federal laws, such as anti-kickback and false claims laws which may apply to items or services reimbursed by any third-party payer, including commercial insurers, and state gift ban and transparency laws, many of which state laws differ from each other in significant ways and often are not preempted by federal laws, thus complicating compliance efforts; and

state laws restricting interactions with healthcare providers and other members of the healthcare community or requiring pharmaceutical manufacturers to implement certain compliance standards.

Because of the breadth of these laws and the narrowness of the statutory exceptions and safe harbors available, it is possible that some of our business activities could be subject to challenge under one or more of such laws. If our operations are found to be in violation of any of such laws or any other governmental regulations that apply to us, we may be subject to, on a corporate or individual basis, penalties, including civil and criminal penalties, damages, fines, the curtailment or restructuring of our operations, the exclusion from participation in federal and state healthcare programs and even imprisonment, any of which could materially adversely affect our ability to operate our business and our financial results. In addition, the cost of implementing sufficient systems, controls, and processes to ensure compliance with all of the aforementioned laws could be significant.

28
Any action for violation of these laws, even if successfully defended, could cause us to incur significant legal expenses and divert management’s attention from the operation of the company’s business. If any of the physicians or other healthcare providers or entities with whom we expect to do business is found not to be in compliance with applicable laws, that person or entity may be subject to criminal, civil or administrative sanctions, including

48

INTELLECTUAL PROPERTY RISKS


exclusions from government funded healthcare programs. Prohibitions or restrictions on sales or withdrawal of future marketed products could materially affect business in an adverse way.

It is not always possible to identify and deter employee misconduct, and the precautions we take to detect and prevent inappropriate conduct may not be effective in controlling unknown or unmanaged risks or losses or in protecting us from governmental investigations or other actions or lawsuits stemming from a failure to be in compliance with such laws or regulations. Efforts to ensure that our business arrangements will comply with applicable healthcare laws may involve substantial costs. It is possible that governmental and enforcement authorities will conclude that our business practices may not comply with current or future statutes, regulations or case law interpreting applicable fraud and abuse or other healthcare laws and regulations. If any such actions are instituted against us and we are not successful in defending ourselves or asserting our rights those actions, our business may be impaired.

We are also subject to anti-bribery and anti-corruption laws, including the U.S. Foreign Corrupt Practices Act (FCPA), the UK Bribery Act, and other similar worldwide anti-bribery laws, as well as various trade laws and regulations (including economic sanctions, export laws, and customs laws), and our failure to comply with those laws could have a material adverse effect on our results of operations and financial conditions.

The FCPA and similar worldwide anti-bribery and anti-corruption laws prohibit companies and their intermediaries from corruptly providing any payments or other benefits to foreign government officials for the purpose of obtaining or retaining business. The U.S. Departments of Justice, Securities & Exchange Commission, Commerce, State and Treasury and other federal agencies and authorities have a broad range of civil and criminal penalties they may seek to impose against corporations and individuals for violations of the FCPA, economic sanctions laws, export control laws, and other federal statutes and regulations, including those established by the Office of Foreign Assets Control, or OFAC. In addition, the U.K. Bribery Act of 2010, or the Bribery Act, prohibits both domestic and international bribery, as well as bribery across both private and public sectors. An organization that fails to prevent bribery by anyone associated with the organization can be charged under the Bribery Act unless the organization can establish the defense of having implemented adequate procedures to prevent bribery.

Similarly, U.S. and similar worldwide trade laws, including economic sanctions, export laws, and customs laws, regulate our ability to conduct business with certain jurisdictions and counterparties, and regulate the ways in which we may export and import products around the world. In connection with these laws, various government agencies may require us to obtain export licenses, may seek to impose modifications to business practices, including cessation of business activities in or with countries, entities, and individuals targeted with sanctions. The breadth and dynamic nature of these laws and regulations may increase compliance costs, and may subject us to fines, penalties and other sanctions.

Novavax has received a number of regulatory approvals in ex-U.S. jurisdictions and has commenced commercial operations in these international locations. Further, a portion of our business with respect to our manufacturing is conducted outside of the United States. We expect our international activities to increase in the future. Though we maintain policies, internal controls and other measures reasonably designed to promote compliance with applicable anti-corruption and trade laws and regulations, our employees or agents may nevertheless engage in improper conduct for which we might be held responsible. Any violations of these anti-corruption or trade laws, or even allegations of such violations, can lead to an investigation and/or enforcement action, which could disrupt our operations, involve significant management distraction, and lead to significant costs and expenses, including legal fees. If we, or our employees or agents acting on our behalf, are found to have engaged in practices that violate these laws and regulations, we could be subject to criminal and civil enforcement action, suffer severe fines and penalties, profit disgorgement, injunctions on future conduct, securities litigation, bans on transacting government business, delisting from securities exchanges and other consequences that may have a material adverse effect on our business, financial condition and results of operations. In addition, our reputation, our revenue or our stock price could be adversely affected if we become the subject of any negative publicity related to actual or potential violations of anti-corruption or trade laws and regulations.

Risks Related to our Intellectual Property

Our success depends on our ability to maintain the proprietary nature of our technology.


Our success in large part depends on our ability to maintain the proprietary nature of our technology and other trade secrets. To do so, we must prosecute and maintain existing patents, obtain new patents and pursue trade secret and other intellectual property protection. We also must operate without infringing the proprietary rights of third-parties or allowing third-parties to infringe our rights. We currently have or have rights to over 350550 U.S. patents and corresponding foreign patents and patent applications covering our technologies. However, patent issues relating to pharmaceuticals and biologics involve complex legal, scientific and factual questions. To date, no consistent policy has emerged regarding the breadth of biotechnology
49

patent claims that are granted by the U.S. Patent and Trademark Office (“USPTO”) or enforced by the federal courts. Therefore, we do not know whether ourany particular patent applications will result in the issuance of patents, or that any patents issued to us will provide us with any competitive advantage. We also cannot be sure that we will develop additional proprietary products that are patentable. Furthermore, there is a risk that others will independently develop or duplicate similar technology or products or circumvent the patents issued to us.

There is a risk that third-parties may challenge our existing patents or claim that we are infringing their patents or proprietary rights. We could incur substantial costs in defending patent infringement suits or in filing suits against others to have their patents declared invalid or claim infringement. It is also possible that we may be required to obtain licenses from third-parties to avoid infringing third-party patents or other proprietary rights. We cannot be sure that such third-party licenses would be available to us on acceptable terms, if at all. If we are unable to obtain required third-party licenses, we may be delayed in or prohibited from developing, manufacturing or selling products requiring such licenses.


Although our patent filings include claims covering various features of our vaccine candidates, including composition, methods of manufacture and use, our patents do not provide us with complete protection against the development of competing products. Some of our know-how and technology is not patentable. To protect our proprietary rights in unpatentable intellectual property and trade secrets, we require employees, consultants, advisors and collaborators to enter into confidentiality agreements. These agreements may not provide meaningful protection for our trade secrets, know-how or other proprietary information.


Failure to obtain trademark registrations for proposed product names/brands, in the U.S. or abroad, may adversely impact our business.

Trademark registration to protect the trademarks for our proposed products will require approval from the USPTO in the United States and in trademark offices throughout the world in our key markets. The USPTO or a trademark office in a key international jurisdiction may refuse registration of any of our trademarks on a variety of potential grounds. If registration is not granted to one of our trademarks in the United States or in another key international jurisdiction, we may be required to adopt an alternative name for that proposed product. If we adopt an alternative name, we would lose the benefit of any existing trademark applications for such developmental candidate and may be required to expend significant additional resources in an effort to identify a suitable product name that would qualify under applicable trademark laws, not infringe the existing rights of third parties and be acceptable to the FDA and other regulatory authorities.

Third parties may claim we infringe their intellectual property rights.


Our research, development and commercialization activities, including any vaccine candidates resulting from these activities, may infringe or be claimedfound to infringe patents or trademarks owned by third-parties and to which we do not hold licenses or other rights. There may be rights we are not aware of, including applications that have been filed, but not published that, when issued, could be asserted against us. These third-parties could bring claims against us, and that wouldmay cause us to incur substantial expenses and, if successful against us, could cause us to pay substantial damages. Further, if a patent or trademark infringement suit were brought against us, we could be forced to stop or delay research, development, manufacturing or sales of the product or biologic drug candidate that is the subject of the suit.


As a result of patent or trademark infringement claims, or in order to avoid potential claims, we may choose or be required to seek a license from the third-party.third party. These licenses may not be available on acceptable terms, or at all. Even if we are able to obtain a license, the license would likely obligate us to pay license fees or royalties or both, and the rights granted to us might be non-exclusive,non- exclusive, which could result in our competitors gaining access to the same intellectual property. Ultimately, we could be prevented from commercializing a product, or be forced to cease some aspect of our business operations, if, as a result of actual or threatened patent or trademark infringement claims, we are unable to enter into licenses on acceptable terms. All of the issues described above could also impact our collaborators, which would also impact the success of the collaboration and therefore us.


There has been substantial litigation and other proceedings regarding patent, trademark, and other intellectual property rights in the pharmaceutical and biotechnology industries.


We may become involved in litigation to protectdefend or enforce our patentsintellectual property or the patentsintellectual property of our collaborators or licensors, which could be expensive and time-consuming.


Competitors may infringe our patents or the patents of our collaborators or licensors. As a result, we may be required to file patent infringement claimssuits to counter infringement forprevent unauthorized use.uses. This can be expensive particularly for a company of our size, and time-consuming. In addition, in an infringement proceeding, a court may decide that a patent of ours is not valid or is unenforceable, or may refuse to stop the other party from using the technology at issue on the grounds that our patents do not cover its technology. An adverse determination of any litigation or defense proceeding could put one or more of our patents at risk of being invalidated or interpreted narrowly and could put our patent applications at the risk of not issuing.

29
Competitors may infringe our trademarks or the trademarks of collaborators or licensors. As a result, we may be required to file suit to counter infringement for unauthorized use of an identical or confusingly similar trademark. This can be expensive and time-consuming.


50

Even if we are successful, litigation may result in substantial costs and distraction to our management. Even with a broad portfolio, we may not be able, alone or with our collaborators and licensors, to prevent misappropriation of our proprietary rights, particularly in countries where the laws may not protect such rights as fully as in the U.S.


Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation, there is a risk that some of our confidential information could be compromised by disclosure during this type of litigation. In addition, during the course of this kind of litigation, there could be public announcements of the results of hearings, motions or other interim proceedings or developments. If investors perceive these results to be negative, the market price for our common stock could be significantly harmed.


The scope, validity, and ownership of our patent claims may be challenged in various venues and, if we do not prevail, our ability to exclude competitors may be harmed, potentially reducing our ability to succeed commercially.


We may be subject to a variety of challenges from third-partiesthird parties that relate to the scope of the claims or to their validity. Such challenges can be mounted in post-grant review, ex parte re-examination, and inter partes review proceedings before the USPTO, or similar adversarial proceedings in other jurisdictions. If we are unsuccessful in any such challenge, the scope of our claims could be narrowed and the patent or claims thereof could be invalidated. Any such outcome could impair our ability to exclude competitors from the market in those countries, potentially impacting our commercial success.


Our patents may be subject to various challenges related to ownership and inventorship, including interference or derivation proceedings. Third-partiesThird parties may assert that they are inventors on our patents or that they are owners of the patents. While we perform inventorship analyses to insure that the correct inventors are listed on our patents, we cannot be certain that a court of competent jurisdiction would arrive at the same conclusions we do. If we are unsuccessful in defending against ownership or inventorship challenges, a court may require us to list additional inventors, may invalidate the patent, or may transfer ownership of the patent to a third-party.third party. Any of these outcomes may harm our ability to exclude competitors and potentially impact our commercial success. Further, if ownership is transferred to a third-partythird party we may be required to seek a license to those rights to preserve our exclusive ability to practice the invention. Such a license may not be available on commercially reasonable terms, or at all. If we are unable to obtain a license, we may be required to expend time, effort, and other resources to design around the patent. Any such license may be non-exclusive and if a competitor is able to obtain a license from the third-party,third party, our ability to exclude that competitor from the market may be negatively impacted.


Even if we are ultimately successful, defending any such challenges may cause us to incur substantial expenses and may require us to divert substantial financial and management resources that we would otherwise be able to devote to our business.


The scope, validity, and ownership of our trademark rights/registrations may be challenged in various venues in the U.S. and abroad and, if we do not prevail, our ability to exclude competitors from using and registering confusingly similar trademarks may be harmed, potentially reducing our ability to succeed commercially.

We may be subject to a variety of challenges from third parties that relate to the validity of our trademark registrations in the U.S. and internationally. Such challenges can be mounted in trademark cancellation and opposition proceedings before the USPTO, or similar adversarial proceedings in other jurisdictions. If we are unsuccessful in any such challenge, our trademark registrations could be narrowed or could be refused or canceled. Any such outcome could impair our ability to exclude competitors from using a confusingly similar mark, potentially impacting our commercial success.

Our trademark registrations may be subject to various challenges related to likelihood of confusion, use of a trademark in commerce, or other grounds in the U.S. and internationally. Third parties may assert that our trademarks infringe on their prior rights or that we are not using a trademark in a particular jurisdiction in connection with the goods/services identified in the trademark registration. While we perform trademark clearance searches and analysis to determine that we are not infringing upon the trademark rights of others, we cannot be certain that a court of competent jurisdiction would arrive at the same conclusions we do. If we are unsuccessful in defending against such challenges, a court may cancel our trademark registration and/or issue an injunction requiring that we cease use of the trademark. We may also not be able to rely on common law rights that we may have in any trademark. Any of these outcomes may potentially impact our commercial success.

Even if we are ultimately successful, defending any such challenges may cause us to incur substantial expenses and may require us to divert substantial financial and management resources that we would otherwise be able to devote to our business.

51

We may need to license intellectual property from third-partiesthird parties and, if our right to use the intellectual property we license is affected, our ability to develop and commercialize our vaccine candidates may be harmed.


We have in the past, and we expect in the future to license intellectual property from third-partiesthird parties and that these licenses will be material to our business. We will not own the patents or patent applications that underlie these licenses, and we willmay not control either the prosecution or the enforcement of the patents. We willUnder such circumstances, we may be forced to rely upon our licensors to properly prosecute and file those patent applications and prevent infringement of those patents.

Our license agreement with Wyeth, which gives us rights to a family of patents and patent applications that are expected to expire in early 2022, covering VLP technology for use in human vaccines in certain fields of use, is non-exclusive. If each milestone is achieved for any particular vaccine candidate, we would likely be obligated to pay an aggregate of $15 million to Wyeth for each vaccine candidate developed and commercialized under the agreement. Achievement of each milestone is subject to many risks, including those described in these risk factors. Annual license fees under the Wyeth agreement aggregate to $0.3 million per year. In September 2015, the Company entered into an amendment to the license agreement with Wyeth. Among other things, the amendment restructured the $3 million milestone payment owed as a result of CPLB’s initiation of a Phase 3 clinical trial for its recombinant trivalent seasonal VLP influenza vaccine candidate in 2014 into a revised milestone payment of $4 million.

While many of the licenses under which we have rights provide us with rights in specified fields, the scope of our rights under these and other licenses may be subject to dispute by our licensors or third-parties.third parties. In addition, our rights to use these technologies and practice the inventions claimed in the licensed patents and patent applications are subject to our licensors abiding by the terms of those licenses and not terminating them. Any of our licenses may be terminated by the licensor if we are in breach of a term or condition of the license agreement, or in certain other circumstances.


Further, any disputes regarding obligations in licenses may require us to take expensive and time-consuming legal action to resolve, and, even if we are successful, may delay our ability to commercialize products and generate revenue. Further, if we are unable to resolve license issues that arise we may lose rights to practice intellectual property that is required to make, use, or sell products. Any such loss could compromise our development and commercialization efforts for current or future product candidates and/or may require additional effort and expense to design around.


Our vaccine candidates and potential vaccine candidates will require several components that may each be the subject of a license agreement. The cumulative license fees and royalties for these components may make the commercialization of these vaccine candidates uneconomical.


If patent laws or the interpretation of patent laws change, our competitors may be able to develop and commercialize our discoveries.


Important legal issues remain to be resolved as to the extent and scope of available patent protection for biopharmaceutical products and processes in the U.S. and other important markets outside the U.S., such as Europe and Japan. In addition, foreign markets may not provide the same level of patent protection as provided under the U.S. patent system. Litigation or administrative proceedings may be necessary to determine the validity and scope of certain of our and others’ proprietary rights. Any such litigation or proceeding may result in a significant commitment of resources in the future and could force us to do one or more of the following: cease selling or using any of our products that incorporate the challenged intellectual property, which would adversely affect our revenue; obtain a license from the holder of the intellectual property right alleged to have been infringed, which license may not be available on reasonable terms, if at all; and redesign our products to avoid infringing the intellectual property rights of third-parties,third parties, which may be time-consuming or impossible to do. In addition, changes in, or different interpretations of, patent laws in the U.S. and other countries may result in patent laws that allow others to use our discoveries or develop and commercialize our products. We cannot provide assurance that the patents we obtain or the unpatented technology we hold will afford us significant commercial protection.


If we do not obtain patent term extension and/or patent term adjustment in the United States under the Hatch- Waxman Act and similar extensions in foreign countries, our ability to exclude competitors may be harmed.

In the United States, the patent term is 20 years from the earliest U.S. non-provisional filing date. Extensions of patent term may be available under certain circumstances. Depending upon the timing, duration and conditions of FDA marketing approval of our product candidates, we may be able to extend the term of one patent that covers a marketed product under the Drug Price Competition and Patent Term Restoration Act of 1984, (the “Hatch-Waxman Amendments”) and similar legislation in the European Union.

The Hatch-Waxman Amendments permit patent term extension of up to five years for a patent covering an approved product as compensation for effective patent term lost during product development and the FDA regulatory review process. We may not receive any extension if we fail to apply within applicable deadlines, fail to apply prior to expiration of relevant patents or otherwise fail to satisfy applicable requirements. Moreover, the length of the extension could be less than we request. If we are unable to obtain patent term extension or the term of any such extension is less than we request, the period during which we can enforce our patent rights for that product will be shortened and our competitors may obtain approval to market competing products sooner.

Patent term covering our products may also be extended for time spent during the prosecution of the patent application in the USPTO. This extension is referred to as Patent Term Adjustment (“PTA”). The laws and regulations
52

governing how the USPTO calculates the PTA is subject to change and changes in the law can reduce or increase any such PTA. Further, the PTA granted by the USPTO may be challenged by a third party. If we do not prevail under such a challenge, the PTA may be reduced or eliminated, shortening the patent term, which may negatively impact our ability to exclude competitors.

Risks Related to OUREmployee Matters, Managing Growth and Information Technology

Our business may be adversely affected if we do not successfully execute our business development initiatives.

We anticipate growing through both internal development projects, as well as external opportunities, which include the acquisition, partnering and in-licensing of products, technologies and companies or the entry into strategic alliances and collaborations. The availability of high quality opportunities is limited, and we may fail to identify candidates that we and our stockholders consider suitable or complete transactions on terms that prove advantageous. In order to pursue such opportunities, we may require significant additional financing, which may not be available to us on favorable terms, if at all. Even if we are able to successfully identify and complete acquisitions, like our business combinations with Novavax CZ (formerly Praha Vaccines) and Novavax AB, strategic transactions involve many risks, including, among others, those related to diversion of management’s attention from other business concerns, unanticipated expenses and liabilities, and increased complexity of our operations, which could prevent us from effectively exploiting acquired facilities, successfully integrating the acquired business and personnel, or fully realizing expected synergies.

To effectively manage our current and future potential growth, we will need to continue to enhance our operational, financial and management processes and to effectively expand, train and manage our employee base. Supporting our growth initiatives will require significant expenditures and management resources, including investments in research and development, manufacturing in-house and through third-party manufacturers and other areas of our business. If we do not successfully manage our growth and do not successfully execute our growth initiatives, then our business and financial results may be adversely impacted, and we may incur asset impairment or restructuring charges.

Security breaches and other disruptions to our information technology systems or those of the vendors on whom we rely could compromise our information and expose us to liability, reputational damage, or other costs.

In the ordinary course of our business, we and many of our current and future strategic partners, vendors, contractors, and consultants collect and store sensitive data, including intellectual property, our proprietary business information and data about our clinical participants, suppliers and business partners and personally identifiable information. The secure maintenance of this information is critical to our operations and business strategy. Some of this information represents an attractive target of criminal attack by malicious third parties with a wide range of motives and expertise, including nation-states, organized criminal groups, “hacktivists,” patient groups, disgruntled current or former employees and others. Our ongoing operating activities also depend on functioning information technology systems. Cyber attacks are of ever-increasing levels of sophistication, and, despite our security measures, our information technology systems and infrastructure and those of our vendors and partners are not immune to such attacks or breaches. In 2020, several domestic and foreign security agencies announced that government actors or government-affiliated actors were specifically targeting organizations engaging in COVID-19 vaccine development and research. Our profile as an OWS recipient and our development of NVX-CoV2373 may result in greater risk of cyber attack. Any such attack could result in a material compromise of our networks, and the information stored there could be accessed, publicly disclosed, lost, rendered, permanently or temporarily, inaccessible. Furthermore, we may not promptly discover a system intrusion. Like other companies in our industry, we have and third parties with connections to our systems or with data relevant to our business have experienced attacks to our data and systems, including malware and computer viruses. Additionally, we partner with sites that store our clinical trial data. Attacks could have a material impact on our business, operations or financial results. Any access, disclosure or other loss of information, whether stored by us or our partners, or other cyberattack causing disruption to our business, including ransomware, could result in reputational, business, and competitive harms, significant costs related to remediation and strengthening our cyber defenses, legal claims or proceedings, government investigations, liability including under laws that protect the privacy of personal information, and increased insurance premium, all of which could adversely affect our business. We also may need to pay a ransom if a “ransomware” infection prevents access or use of our systems and we may face reputational and other harms in addition to the cost of the ransom if an attacker steals certain critical data in the course of such an attack.

Compliance with global privacy and data security requirements could result in additional costs and liabilities to us or inhibit our ability to collect and process data globally, and our failure to comply with data protection laws and regulations could lead to government enforcement actions, which would cause our business and reputation to suffer.

53

Evolving state, federal and foreign laws, regulations and industry standards regarding privacy and security apply to our collection, use, retention, protection, disclosure, transfer and other processing of personal data. Privacy and data protection laws may be interpreted and applied differently from country to country and may create inconsistent or conflicting requirements, which increases the costs incurred by us in complying with such laws, which may be substantial. For example, the European Union’s General Data Protection Regulation 2016/679 (“GDPR”), which became effective in May 2018, imposes a broad array of requirements for processing personal data, including elevated disclosure requirements regarding collection and use of such data, requirements that companies allow individuals to obtain copies or demand deletion of personal data held by those companies, limitations on retention of information, and public disclosure of significant data breaches, among other things. The GDPR provides for substantial penalties for non-compliance of up to the greater of €20 million or 4% of global annual revenue for the preceding financial year. FromJanuary1, 2021 theGDPRhas been retainedin U.K., as it forms part of the law of England and Wales, Scotland and Northern Ireland by virtue of section 3 of the European Union (Withdrawal) Act 2018, as amended by the Data Protection, Privacy and Electronic Communications (Amendments etc.) (EU Exit) Regulations 2019 (SI 2019/419) (“UK GDPR”), alongside the U.K.’s Data Protection Act 2018. Our efforts to comply with GDPR, the UK GDPR and other privacy and data protection laws impose significant costs and challenges that are likely to increase over time, and we are exposed to substantial penalties or litigation related to violations of existing or future data privacy laws and regulations.

Furthermore, the GDPR and UK GDPR impose strict restrictions surrounding the transfer of personal data to countries outside the EEA and the U.K., including to the United States. In 2016, the EU and United States agreed to a transfer framework for data transferred from the European Union to the United States, called the EU-US Privacy Shield. On July 16, 2020, however, the Court of Justice of the European Union issued a decision that declared the Privacy Shield framework invalid and raised questions about whether the European Commission’s Standard Contractual Clauses (“SCCs”), an alternative to the Privacy Shield, can lawfully be used for cross-border data transfers. On June 4, 2021, the European Commission adopted new SCCs under the GDPR for personal data transfers outside of the EEA. Under this legal mechanism, we may have obligations to conduct transfer impact assessments for such cross-border data transfers and implement additional security measures. As we incorporate the new SCCs into our contractual arrangements, we may be required to expend significant resources to update our contractual arrangements and to comply with the new obligations. If we are unable to implement a valid compliance mechanism for cross-border personal information transfers, we may face increased exposure to regulatory actions, substantial fines and injunctions against processing or transferring personal information from Europe to the United States. An inability to import personal information from Europe to the United States may significantly and negatively impact our business operations, including by limiting our ability to conduct clinical trials in Europe; limiting our ability to collaborate with contract research organizations, service providers, contractors and other companies subject to the GDPR; or requiring us to increase our data processing capabilities in Europe at significant expense.

Privacy laws and regulations are also expanding in the United States. The California Consumer Privacy Act (“CCPA”), which became effective January 1, 2020, substantially expands privacy obligations of many businesses, requiring new disclosures to California consumers, imposing new rules for collecting or using information about minors and affording consumers new abilities, such as the right to know whether their data is sold or disclosed and to whom, the right to request that a company delete their personal information, the right to opt-out of the sale of personal information and the right to non-discrimination in terms of price or service when a consumer exercises a privacy right. Like the GDPR, the CCPA establishes potentially significant penalties for violation. The CCPA also provides a private right of action along with statutory damages for certain data breaches, which is expected to increase risks related to data breach litigation. The California Privacy Rights Act (“CPRA”), which will become operational in 2023, expands on the CCPA, creating new consumer rights and protections, including the right to correct personal information, the right to opt out of the use of personal information in automated decision making, the right to opt out of “sharing” consumer’s personal information for cross-context behavioral advertising, and the right to restrict use of and disclosure of sensitive personal information, including geolocation data to third parties. Similar restrictions are also included in the Virginia Consumer Data Protection Act (“VCDPA”) and the Colorado Privacy Act (“CPA”), the first comprehensive state privacy statutes to follow the CCPA. We will need to evaluate and potentially update our privacy program to seek to comply with the CPRA, VCDPA, CPA and other US privacy laws, and we expect to incur additional expense in our effort to comply.

There is also a likelihood that other states will follow California, Colorado and Virginia in enacting more comprehensive privacy laws. Such legislation, if enacted, may add additional complexity, variation in requirements, restrictions and potential legal risk, and may require additional investment of resources in compliance programs, impact strategies, reduce the availability of previously useful data and result in increased compliance costs and/or changes in business practices and policies.

Collaborations and contracts of our wholly owned subsidiaries Novavax AB and Novavax CZ, with regional partners, such as SIIPL, Takeda and SK bioscience, as well as with international providers, expose us to additional risks associated with doing business outside the U.S.
54


Swedish-based Novavax AB and Czech Republic-based Novavax CZ are wholly owned subsidiaries of Novavax, Inc. We also have entered into a supply and license agreement with SIIPL, collaboration and license agreements with each of Takeda and SK bioscience and other agreements and arrangements with foreign governments and companies in other countries. We plan to continue to enter into collaborations or partnerships with companies, non-profit organizations and local governments in various parts of the world. Risks of conducting business outside the U.S. include negative consequences of:

the costs associated with seeking to comply with multiple regulatory requirements that govern our ability to develop, manufacture and sell products in local markets;

failure to comply with anti-bribery laws such as the U.S. Foreign Corrupt Practices Act and similar anti-bribery laws in other jurisdictions;

new or changes in interpretations of existing trade protections measures, including tariffs, embargoes and import and export licensing requirements;

difficulties in and costs of staffing, managing and operating our international operations;

changes in environmental, health and safety laws;

fluctuations in foreign currency exchange rates;

new or changes in interpretations of existing tax laws;

political instability and actual or anticipated military or potential conflicts (including, without limitation, the ongoing conflict between Russia and Ukraine, and a wider European or global conflict);

economic instability, inflation, recession and interest rate fluctuations;

minimal or diminished protection of intellectual property in many jurisdictions; and

possible nationalization and expropriation.

These risks, individually or in the aggregate, could have a material adverse effect on our business, financial conditions, results of operations and cash flows.

If we are unable to attract or retain key management or other personnel, our business, operating results and financial condition could be materially adversely affected.

We depend on our senior executive officers, as well as key scientific and other personnel. The loss of these individuals could harm our business and significantly delay or prevent the achievement of research, development or business objectives. Turnover in key executive positions resulting in lack of management continuity and long-term history with our Company could result in operational and administrative inefficiencies and added costs.

We may not be able to attract qualified individuals for key positions on terms acceptable to us. Competition for qualified employees is intense among pharmaceutical and biotechnology companies, and the loss of qualified employees, or an inability to attract, retain and motivate additional highly skilled employees could hinder our ability to complete clinical trials successfully and otherwise develop marketable products.

We also rely from time to time on outside advisors who assist us in formulating our research and development and clinical strategy. We may not be able to attract and retain these individuals on acceptable terms, which could delay our development efforts.

Risks Related to Our Convertible SENIORSenior Notes

55


Servicing our 3.75% convertible senior unsecured notes due 2023 (the “Notes”) requires a significant amount of cash, and we may not have sufficient cash flow to pay our debt.


In 2016, we issued $325 million aggregate principal amount of Notes. Our ability to make scheduled payments of the principal of, to pay interest on, or to refinance our indebtedness, including the Notes, depends on our future performance, which is subject to economic, financial, competitive and other factors beyond our control. We do not expect our business to be able to generate cash flow from operations in the foreseeable future, sufficient to service our debt and make necessary capital expenditures and may therefore be required to adopt one or more alternatives, such as selling assets, restructuring debt or obtaining additional equity capital on terms that may be onerous or highly dilutive. Our ability to refinance our indebtedness, which is non-callable and matures in 2023, will depend on the capital markets and our financial condition at such time. We may not be able to engage in any of these activities or engage in these activities on desirable terms, which could result in a default on our debt obligations, and limit our flexibility in planning for and reacting to changes in our business.

31


We may not have the ability to raise the funds necessary to repurchase the Notes as required upon a fundamental change, and our future debt may contain limitations on our ability to repurchase the Notes.


Holders of the Notes will have the right to require us to repurchase their Notes for cash upon the occurrence of a fundamental change at a fundamental change repurchase price equal to 100% of the principal amount of the Notes to be repurchased,plus accrued and unpaid interest, if any. A fundamental change may also constitute an event of default or prepayment under, and result in the acceleration of the maturity of, our then-existing indebtedness. We cannot assure you that we will have sufficient financial resources, or will be able to arrange financing, to pay the fundamental change repurchase price in cash with respect to any Notes surrendered by holders for repurchase upon a fundamental change. In addition, restrictions in our then existing credit facilities or other indebtedness, if any, may not allow us to repurchase the Notes upon a fundamental change. Our failure to repurchase the Notes upon a fundamental change when required would result in an event of default with respect to the Notes which could, in turn, constitute a default under the terms of our other indebtedness, if any. If the repayment of the related indebtedness were to be accelerated after any applicable notice or grace periods, we may not have sufficient funds to repay the indebtedness and repurchase the Notes.


Capped call transactions entered into in connection with our Notes may affect the value of our common stock.


In connection with our Notes, we entered into capped call transactions (the “capped call transactions”) with certain financial institutions. The capped call transactions are expected to generally reduce the potential dilution upon conversion of the Notes into shares of our common stock.


In connection with establishing their initial hedges of the capped call transactions, these financial institutions or their respective affiliates entered into various derivative transactions with respect to our common stock and/or to purchase our common stock. The financial institutions, or their respective affiliates, may modify their hedge positions by entering into or unwinding various derivatives with respect to our common stock and/or purchasing or selling our common stock or other securities of ours in secondary market transactions prior to the maturity of the Notes. This activity could also cause or avoid an increase or a decrease in the market price of our common stock or the Notes, which could affect the value of our common stock.

RISKS RELATED TO OUR COMMON STOCK AND ORGANIZATIONAL STRUCTURE


Risks Related to Ownership of Our Common Stock

Because our stock price has been and will likely continue to be highly volatile, the market price of our common stock may be lower or more volatile than expected.


Our stock price has been highly volatile. From January 1, 2021 through December 31, 2021, the closing sale price of our common stock has been as low as $112.98 per share and as high as $319.93 per share. The stock market in general and the market for biotechnology companies in particular have experienced extreme volatility that has often been unrelated to the operating performance of particular companies. From January 1, 2017 through December 31, 2017, the closing sale price of our common stock has been as low as $0.73 per share and as high as $1.63 per share. The market price of our common stock may be influenced by many factors, including:

·future announcements about us or our collaborators or competitors, including the results of testing, technological innovations or new commercial products;
·clinical trial results;
·depletion of our cash reserves;
·sale of equity securities or issuance of additional debt;
·announcement by us of significant strategic partnerships, collaborations, joint ventures, capital commitments or acquisitions;
·changes in government regulations;
·impact of competitor successes and in particular development success of vaccine candidates that compete with our own vaccine candidates;
·developments in our relationships with our collaboration partners;
·announcements relating to health care reform and reimbursement levels for new vaccines and other matters affecting our business and results, regardless of accuracy;
·sales of substantial amounts of our stock by existing stockholders (including stock by insiders or 5% stockholders);
·development, spread or new announcements related to pandemic diseases;
·litigation;
·public concern as to the safety of our products;

32

·significant set-backs or concerns with the industry or the market as a whole;
·regulatory inquiries, reviews and potential action, including from the FDA or the SEC;
·recommendations by securities analysts or changes in earnings estimates; and
·the other factors described in this Risk Factors section.

In addition, the stock market in general, and the market for biotechnology companies in particular, have experienced extreme price and volume fluctuations that have particularly affected the market price for many of those companies. These fluctuations have often been unrelated to the operating performance of these companies. These broad market fluctuations may cause the market price of our common stock to be lower or more volatile than expected.

The Nasdaq Global Select Market


Furthermore, given the global focus on the COVID-19 pandemic and our investment in developing a COVID-19 vaccine, information in the public arena on this topic, whether or not accurate, has had and will likely continue to have an outsized impact (positive or negative) on our stock price. Information related to our development, manufacturing, regulatory and commercialization efforts with respect to NVX-CoV2373, or information regarding such efforts by competitors with respect to their COVID-19 vaccines and vaccine candidates, may meaningfully impact our stock price. As a listing requirement; if a participating company no longer meets such requirements and failsresult of this
56

volatility, you may not be able to correct the listing deficiency, its stock may be delisted.

The Nasdaq Global Select Market (“Nasdaq”), on which oursell your common stock is listed and traded, has listing requirements that include a $1 minimum closing bid price requirement. If we fail to satisfy thisat or other listing requirements, Nasdaq may elect, subject to any potential cure periods, to initiate a process that may delist our common stock. Should such a delisting occur, it may adversely impact the liquidity andabove your initial purchase price. The market price of our common stock impedemay be influenced by many other factors, including:


future announcements about us or our collaborators or competitors, including the results of testing, technological innovations or new commercial products;

clinical trial results;

delays in making regulatory submissions;

depletion of our cash reserves;

sale of equity securities or issuance of additional debt;

announcement by us of significant strategic partnerships, collaborations, joint ventures, capital commitments or acquisitions;

changes in government regulations;

impact of competitor successes and in particular development success of vaccine candidates that compete with our own vaccine candidates;

developments in our relationships with our collaboration and funding partners;

announcements relating to health care reform and reimbursement levels for new vaccines and other matters affecting our business and results, regardless of accuracy;

sales of substantial amounts of our stock by us or existing stockholders (including stock by insiders or 5% stockholders);

development, spread or new announcements related to pandemic diseases;

litigation;

public concern as to the safety of our products;

significant set-backs or concerns with the industry or the market as a whole;

regulatory inquiries, reviews and potential action, including from the FDA or the SEC;

recommendations by securities analysts or changes in earnings estimates; and

the other factors described in this Risk Factors section.

In the past, following periods of volatility in the market price of a company’s securities, securities class-action litigation often has been instituted against that company. Such litigation, if instituted against us, could cause us to incur substantial costs to defend such claims and divert management’s attention and resources, which could seriously harm our business, financial condition, and results of operations, and prospects.

Raising additional capital by issuing securities or through collaboration and licensing arrangements may cause dilution to existing stockholders or require us to relinquish rights to our technologies or vaccine candidates.

57

If we are unable to partner with a third-party to advance the development of one or more of our vaccine candidates, we will need to raise money through additional debt or equity financings. To the extent that we raise additional capital by issuing equity securities, our stockholders will experience immediate dilution, which may be significant. There is also a risk that such equity issuances may cause an ownership change under the Internal Revenue Code of 1986, as amended, and similar state provisions, thus limiting our ability to use our net operating loss carryforwards and credits. To the extent that we raise additional capital through licensing arrangements or arrangements with collaborative partners, we may be required to relinquish, on terms that may not be favorable to us, rights to some of our technologies or vaccine candidates that we would otherwise seek to develop or commercialize ourselves. In addition, economic conditions may also negatively affect the desire or ability of potential collaborators to enter into transactions with us. They may also have to delay or cancel research and would constitute a fundamental change under our Notes.

development projects or reduce their overall budgets.


Provisions of our Second Amended and Restated Certificate of Incorporation and Amended and Restated By-Laws and Delaware law could delay or prevent the acquisition of the Company, even if such acquisition would be beneficial to stockholders, and could impede changes in our Board.


Provisions in our organizational documents could hamper a third-party’sthird party’s attempt to acquire, or discourage a third-party from attempting to acquire control of, the Company. Stockholders who wish to participate in these transactions may not have the opportunity to do so. Our organizational documents also could limit the price investors are willing to pay in the future for our securities and make it more difficult to change the composition of our Board in any one year. Certain provisions include the right of the existence ofFor example, our organizational documents provide for a staggered board with three classes of directors serving staggered three-year terms and advance notice requirements for stockholders to nominate directors and make proposals.


As a Delaware corporation, we are also afforded the protections of Section 203 of the Delaware General Corporation Law, which will prevent us from engaging in a business combination with a person who acquires at least 15% of our common stock for a period of three years from the date such person acquired such common stock, unless advance board or stockholder approval was obtained.


Any delay or prevention of a change of control transaction or changes in our Board or management could deter potential acquirers or prevent the completion of a transaction in which our stockholders could receive a substantial premium over the then current market price for their shares.


We have never paid dividends on our capital stock, and we do not anticipate paying any such dividends in the foreseeable future.


We have never paid cash dividends on our common stock. We currently anticipate that we will retain all of our earnings for use in the development of our business and do not anticipate paying any cash dividends in the foreseeable future. As a result, capital appreciation, if any, of our common stock would be the only source of gain for stockholders until dividends are paid, if at all.


General Risk Factors

Litigation or regulatory investigations could have a material adverse impact on our results of operation and financial condition.

In addition to intellectual property litigation, from time to time, we may be subject to other litigation or regulatory investigations. Regardless of the merits of any claims that may be brought against us, litigation or regulatory investigations could result in a diversion of management’s attention and resources and we may be required to incur significant expenses defending against these claims. If we are unable to prevail in litigation or regulatory investigations, we could incur substantial liabilities. Where we can make a reasonable estimate of the liability relating to pending litigation and determine that it is probable, we record a related liability. As additional information becomes available, we assess the potential liability and revise estimates as appropriate. However, because of uncertainties relating to litigation, the amount of our estimates could be wrong.

We or the third parties upon whom we depend may be adversely affected by natural or man-made disasters or public health emergencies, such as the COVID-19 pandemic.

Our operations, and those of our clinical research organizations, contract manufacturing organizations, vendors of materials needed in manufacturing, collaboration partners, distributors and other third parties upon whom we depend, could be subject to fires, extreme weather conditions, earthquakes, power shortages, telecommunications failures, water shortages,
58

floods, hurricanes, typhoons, war, political unrest, sabotage or terrorism and other natural or man-made disasters, as well as public health emergencies, such as the COVID-19 pandemic. The occurrence of any of these business disruptions could prevent us from using all or a significant portion of our facilities and it may be difficult or impossible for us to continue certain activities for a substantial period of time. The disaster recovery and business continuity plans we have in place may prove inadequate in the event of a serious disaster or similar event and we may incur substantial expenses and delays as a result. Our ability to manufacture our product candidates and obtain necessary clinical supplies for our product candidates could be disrupted if the operations of our contract manufacturing organizations or suppliers are affected by a natural or man-made disaster, or a public health emergency.

The outbreak of COVID-19 may materially and adversely affect our business and our financial results.

The COVID-19 pandemic continues to present substantial global economic and public health challenges, which may materially and adversely impact our business, financial condition and results of operations. In response to COVID-19, various aspects of our business operations have been, and could continue to be, disrupted. We continue to implement a work from home policy, with our administrative employees working outside of our offices, and on-site staff restricted to only those required to execute certain laboratory and related support activities. Working remotely could increase our cybersecurity risk, create data accessibility concerns, and make us more susceptible to communication disruptions, any of which could adversely impact our business operations. In addition, as a result of state or local restrictions, our on-site staff conducting research and development may not be able to access our laboratories, and these core activities may be significantly limited or curtailed, possibly for extended periods of time. Travel restrictions and other governmental measures may also result in a disruption or delay in the performance of our third-party contractors and suppliers. If such third parties are unable to adequately satisfy their contractual commitments to us in a timely manner, our business could be adversely affected. Furthermore, while some jurisdictions have recently started to phase out restrictions imposed on commercial activities at varying degrees, a resurgence of COVID-19, coupled with a potential surge in variant strains of COVID-19, in certain geographies could result in restrictions being reinstated.

Our clinical trials, whether planned or ongoing, may be affected by the COVID-19 pandemic. Study procedures (particularly any procedures that may be deemed non-essential), site initiation, participant recruitment and enrollment, participant dosing, shipment of our product candidates, distribution of clinical trial materials, study monitoring, site inspections and data analysis may be paused or delayed due to changes in hospital or research institution policies, federal, state or local regulations, prioritization of hospital and other medical resources toward efforts to treat or prevent COVID-19, or other reasons related to the pandemic. In addition, there could be a potential effect of COVID-19 to the operations of the FDA or other health authorities, which could result in delays of reviews and approvals, including with respect to our product candidates. Any prolongation or de-prioritization of our clinical trials or delay in regulatory review resulting from such disruptions could materially affect the development and study of our product candidates.

The trading prices for our common stock and that of other biopharmaceutical companies have been highly volatile due to the COVID-19 pandemic, especially as a result of investor concerns and uncertainty related to the impact of the outbreak on the economies of countries worldwide. These broad market and industry fluctuations, as well as general economic, political and market conditions, may negatively impact the market price of shares of our common stock.

The COVID-19 pandemic continues to rapidly evolve. The extent to which the outbreak impacts our business, preclinical studies and clinical trials will depend on future developments, which are highly uncertain and cannot be predicted with confidence, such as the ultimate geographic spread of the disease, the emergence of variant strains, the duration of the pandemic, travel restrictions and social distancing in the U.S. and other countries, business closures or business disruptions and the effectiveness of actions taken in the U.S. and other countries to contain and treat the disease.

The United Kingdom’s withdrawal from the European Union could result in increased regulatory and legal complexity, which may make it more difficult for us to do business in the UK and/or Europe and impose additional challenges in securing regulatory approval of our product candidates in the UK and/or Europe.

The United Kingdom’s exit from the European Union as of January 31, 2020, with a transitional period up to December 31, 2020, commonly referred to as “Brexit”, has caused political and economic uncertainty, including in the regulatory framework applicable to our operations and vaccine candidates in the United Kingdom and the European Union, and this uncertainty may persist for years. Brexit could, among other outcomes, disrupt the free movement of goods, services and people between the United Kingdom and the European Union, and result in increased legal and regulatory complexities, as well as potential higher costs of conducting business in Europe. As one of the Brexit consequences, the EMA has relocated from the United Kingdom to the Netherlands. This has led to a significant reduction of the EMA workforce, which has resulted and could further result in significant disruption and delays in its administrative procedures, such as granting clinical trial authorization or opinions for marketing authorization, disruption of importation and export of active substance and other
59

components of new drug formulations, and disruption of the supply chain for clinical trial product and final authorized formulations. As the European Union granted conditional marketing authorization for NVX-CoV2373 after January 1, 2021, it is not grandfathered in the UK. We therefore must seek to obtain a separate marketing authorization for the UK, increasing our regulatory burden.

The cumulative effects of the disruption to the regulatory framework may add considerably to the development lead time to marketing authorization and commercialization of products in the European Union and/or the United Kingdom. It is possible that there will be increased regulatory complexities, which can disrupt the timing of our clinical trials and regulatory approvals. In addition, changes in, and legal uncertainty with regard to, national and international laws and regulations may present difficulties for our clinical and regulatory strategy. Any delay in obtaining, or an inability to obtain, any marketing approvals, as a result of Brexit or otherwise, would prevent us from commercializing our product candidates in the United Kingdom and/or the European Union and restrict our ability to generate revenues and achieve and sustain profitability.

In addition, as a result of Brexit, other European countries may seek to conduct referenda with respect to their continuing membership with the European Union. Given these possibilities and others we may not anticipate, as well as the absence of comparable precedent, it is unclear what financial, regulatory and legal implications the withdrawal of the United Kingdom from the European Union will have, how such withdrawal will affect us, and the full extent to which our business could be adversely affected.

We are increasingly a target for public scrutiny, and our business may be impacted by unfavorable publicity.

Given that COVID-19 represents an unprecedented urgent public health crisis, that we are developing NVX-CoV2373 as a COVID-19 vaccine candidate, and that we have received significant funding from the U.S. and foreign governments and other sources to support the development and potential commercialization of NVX-CoV2373, we have observed and are likely to continue to face significant public attention and scrutiny over the complex decisions we have made and will be making regarding the development, testing, manufacturing, allocation and pricing of NVX-CoV2373. If we are unable to successfully manage these risks, we could face significant reputational harm, which could negatively affect our stock price. The intense public interest, including speculation by the media, in the development of NVX-CoV2373 has caused significant volatility in our stock price, which we expect to continue as data and other information from our ongoing clinical trials become publicly available. If concerns should arise about the actual or anticipated efficacy or safety of any of our product candidates, such concerns could adversely affect the market’s perception of these candidates, which could lead to a decline in investors’ expectations and a decline in the price of our common stock.

The increasing use of social media platforms presents new risks and challenges to our business.

Social media is increasingly being used to communicate about pharmaceutical companies’ research, product candidates, and the diseases such product candidates are being developed to prevent. Social media practices in the pharmaceutical industry continue to evolve and regulations relating to such use are not always clear. This evolution creates uncertainty and risk of noncompliance with regulations applicable to our business, resulting in potential regulatory actions against us. For example, subjects may use social media channels to comment on their experience in an ongoing blinded clinical trial or to report an alleged adverse event. When such events occur, there is a risk that we fail to monitor and comply with applicable adverse event reporting obligations or we may not be able to defend our business or the public’s legitimate interests in the face of the political and market pressures generated by social media due to restrictions on what we may say about our investigational product candidates. There is also a risk of inappropriate disclosure of sensitive information or negative or inaccurate posts or comments about us on any social media or networking website. If any of these events were to occur or we otherwise fail to comply with applicable regulations, we could incur liability, face regulatory actions, or incur reputational or other harm to our business.

Item 3.LEGAL PROCEEDINGS

Item 3. LEGAL PROCEEDINGS

On February 26, 2021, a Novavax stockholder named Thomas Golubinski filed a derivative complaint against members of the Novavax board of directors and members of senior management in the Delaware Court of Chancery, captioned Thomas Golubinski v. Richard H. Douglas, et al., No. 2021-0172-JRS. Novavax is deemed a nominal defendant. Golubinski challenged equity awards made in April 2020 and in June 2020 on the ground that they were “spring-loaded,” that is, made at a time when such board members or members of senior management allegedly possessed undisclosed positive material information concerning the Company. The complaint asserted claims for breach of fiduciary duty, waste, and unjust enrichment. The plaintiff sought an award of damages to the Company, an order rescinding both awards or requiring disgorgement, and an award of attorneys’ fees incurred in connection with the litigation. On May 10, 2021, the defendants moved to dismiss the complaint in its entirety. On June 17, 2021, the Company’s stockholders voted FOR ratification of the April 2020 awards and ratification of the June 2020 awards. Details of the ratification proposals are set forth in the Company’s Definitive Proxy Statement filed with the SEC on May 3, 2021. The results of the vote were disclosed in the Company’s Current Report on Form 8-K filed with the SEC on June 24, 2021. Thereafter, the plaintiff stipulated that, as a result of the outcome of the June 17, 2021 vote, the plaintiff no longer intends to pursue the lawsuit or any claim arising from the April 2020 and June 2020 awards. On August 23, 2021, the plaintiff filed a motion seeking an award of attorneys’ fees and expenses, to which the defendants filed an opposition. The action is currently stayed, and upon final resolution of the plaintiff’s motion for an award of fees and expenses, the action will be automatically dismissed.

On November 12, 2021, Sothinathan Sinnathurai filed a purported class action in the U.S. District Court for the District of Maryland against Novavax and certain members of senior management, captioned Sothinathan Sinnathurai v. Novavax, Inc., et al., No. 8:21-cv-02910-TDC (the “Sinnathurai Action”). The complaint in the Sinnathurai Action alleges that the defendants made certain purportedly false and misleading statements concerning NVX-CoV2373, including with respect to the Company’s manufacturing capabilities and NVX-CoV2373’s regulatory and commercial prospects. The purported class is defined as those who purchased or otherwise acquired Novavax securities between March 2, 2021 and October 19, 2021. The complaint demands an award of damages on behalf of the purported class and attorneys’ fees incurred in connection with the litigation. On January 26, 2022, the court entered an order designating David Truong, Nuggehalli Balmukund Nandkumar, and Jeffrey Gabbert as co-lead plaintiffs in the Sinnathurai Action. The court has ordered the co-lead plaintiffs to file an amended complaint by March 11, 2022. The Company’s response to the amended complaint is due April 25, 2022.

After the Sinnathurai Action was filed, three derivative lawsuits were filed and are currently pending in the U.S. District Court for the District of Maryland: Robert E. Meyer v. Stanley C. Erck, et al., No. 8:21-cv-02996-TDC (the “Meyer Action”), Shui Shing Yung v. Stanley C. Erck, et al., No. 8:21-cv-03248-TDC (the “Yung Action”), and William Kirst, et al. v. Stanley C. Erck, et al., No. 8:22-cv-00024-TDC (the “Kirst Action”). The derivative lawsuits name members of the board of directors and certain members of senior management as defendants. Novavax is deemed a nominal defendant. The derivative plaintiffs assert derivative claims arising out of substantially the same alleged facts and circumstances as the Sinnathurai Action. Collectively, the derivative complaints assert claims for breach of fiduciary duty, insider selling, unjust enrichment, violation of federal securities law, abuse of control, waste, and mismanagement. Plaintiffs seek declaratory and injunctive relief, as well as an award of monetary damages and attorneys’ fees. Novavax removed the Kirst Action from the Circuit Court for Montgomery County, Maryland. On February 7, 2022, the plaintiffs in the Kirst Action filed a motion to remand the action to state court and, in response, the Company has filed an opposition. The Court also entered an order tolling the defendants’ time to respond to the complaints in the Meyer and Yung Actions pending submission of a joint proposed briefing schedule on any

anticipated motion practice in those cases by March 25, 2022. On February 4, 2022, the Court entered an order consolidating the Meyer and Yung Actions.

Although the outcomes of these other legal proceedings are inherently difficult to predict, we do not expect the resolution of these other legal proceedings to have noa material pending legal proceedings.

Overview


We are a clinical-stage biotechnology company focused onthat promotes improved health globally through the discovery, development, and commercialization of recombinant nanoparticleinnovative vaccines and adjuvants. Using innovativeto prevent serious infectious diseases. The Company's proprietary recombinant nanoparticle vaccine technology weplatform harnesses the power and speed of genetic engineering to efficiently produce highly immunogenic nanoparticles designed to address urgent global health needs.

Our vaccine candidates to efficientlyin our near-term pipeline, including both NVX-CoV2373 and effectively respond to both known and emerging disease threats. Our vaccine candidatesthe NanoFlu Program, are genetically engineered, three-dimensional nanostructures that incorporateof recombinant proteins critical to disease pathogenesispathogenesis. At the forefront of our pipeline is our COVID-19 vaccine candidate, NVX-CoV2373. NVX-CoV2373 has received provisional approval, conditional marketing authorization (“CMA”) and mayemergency use authorization (“EUA") from multiple regulatory authorities globally. In January 2022, we also submitted a request to the FDA for emergency use authorization of NVX-CoV2373. We also advanced our NanoFlu Program vaccine program through a Phase 3 clinical trial, which demonstrated positive top-line results and achieved statistical significance in key secondary endpoints. Additionally, we are currently evaluating a COVID-influenza combination vaccine in a Phase 1/2 clinical trial, which combines the company's NVX-CoV2373 and our NanoFlu Program vaccine candidates.We believe that our protein-subunit-based candidates elicit differentiated immune responses whichthat may be more efficacious than naturally occurring immunity or traditional vaccine. Our product pipeline targets a variety of infectious diseases, with clinicalother vaccine approaches. These vaccine candidates against respiratory syncytial virus (“RSV”), influenza and Ebola virus (“EBOV”), and preclinical programs for other infectious disease vaccine candidates.

We are also developing immune stimulatingincorporate Novavax' proprietary saponin-based adjuvants through our wholly owned Swedish subsidiary, Novavax AB. Our leadMatrix-M™ adjuvant Matrix-M™, has been shown to enhance the immune responsesresponse and was well-toleratedstimulate high levels of neutralizing antibodies.


We remain focused on the manufacturing and distribution to bring our NVX-CoV2373 vaccine candidate to market following global regulatory authorizations. Through ongoing booster studies in multipleour clinical trials, that we have conducted.

Product Pipeline

Our product pipeline includes vaccine candidates engineered to elicit differentiated immune responses with the potential to provide increased protection. Our nanoparticle technology targets antigens with conserved epitopes essential for viral function. Our vaccine technology has the potential to be applied broadly to a wide variety of human infectious diseases.

Respiratory Syncytial Virus

We have identified three susceptible target populations that could benefit fromas well as the development of COVID-19 variant strain vaccine candidates, we continue to collect data to characterize and optimize vaccine performance. We expect to leverage these clinical insights to advance the use of our respiratory syncytial virus fusion (F) protein nanoparticleCOVID-19 vaccine candidate (“RSV F Vaccine”)for both primary vaccination around the globe, to use within a booster setting, and for the pediatric population amidst the ongoing and evolving COVID-19 pandemic.


Although NVX-CoV2373 and the NanoFlu Program are our near-term priorities, we remain optimistic that the additional programs in different formulations: infants via maternal immunization, older adults (60 years of age and older) and children six months to five years of age (“pediatrics”). We believeour pipeline, including our vaccine candidates in our RSV FProgram, and our partner-led malaria candidates, present strong opportunities for future development.

Business Highlights

Fourth Quarter 2021 and Recent Highlights

Achieved Multiple Regulatory Authorizations Globally for COVID-19 Vaccine represents a multi-billion dollar revenue opportunity, worldwide. Currently, there is no approved RSV vaccine available.

COVID-19 Vaccine Advanced Purchase Agreement
Executed APA with Israel’s Ministry of effortHealth to develop an RSV vaccine, there are currently no licensed vaccines. We made a breakthrough in developing a vaccine that targets the fusion protein, or F-protein, of the virus. The F-protein has highly conserved amino acid sequences, called antigenic sites, which we believe are ideal vaccine targets. We genetically engineered a novel F-protein antigen resulting in enhanced immunogenicity by exposing a number of these antigenic sites. The Novavax RSV F Vaccine assembles into a recombinant protein nanoparticle optimized for F-protein antigen presentation. We are seeking to bring the first RSV vaccine to market to combat the 64 million RSV infections that occur globally each year.2,3

RSV Infants via Maternal Immunization Program

Burden of Disease

RSV is the most common cause of lower respiratory tract infections and the leading viral cause of severe lower respiratory tract disease in infants and young children worldwide.4,5 In the U.S., RSV is the leading cause of hospitalization of infants, and globally, is second only to malaria as a cause of death in children under one year of age.6,7 Despite the induction of post-infection immunity, repeat infection and lifelong susceptibility to RSV is common.8,9

Clinical Trial Update

Prepare Phase 3 Trial (Ongoing)

We initiated Prepare™, a global pivotal Phase 3 clinical trial of our RSV F Vaccine, using aluminum phosphate as an adjuvant, in approximately 4,600 healthy pregnant women in December 2015. The primary objective of the Prepare trial is to determine the efficacy of maternal immunization with the RSV F Vaccine against symptomatic RSV lower respiratory tract infection with objective measures of medical significance in infants throughsupply a minimum of 5 million vaccine doses

The Prepare2022


COVID-Influenza Combination Vaccine Clinical Development
Ongoing Phase 1/2 trial utilizes a group sequential design. We will initiate a prescribed interim efficacy analysis when we have approximately 4,600 enrolled women, currentlyfor COVID-influenza combination vaccine
Data is expected in mid-2018, and report results from this interim analysis, expected in early 2019. Assuming successful interim analysis results, the trial would be concluded without further enrollment. In 2017, with approximately 1,300 participants in the Prepare trial, we conducted an informational analysis that provided a positive indication of our vaccine’s potential efficacy (between 45% and 100%10), further de-risking this important program. These results have allowed usApril 2022
Expect to make go-forward decisions relating to various program-related activities.

The Prepare trial is supported by a grant (the “Grant”) of up to $89.1 million from BMGF. The Grant supports development activities, product licensing efforts and World Health Organization (“WHO”) prequalification of our RSV F Vaccine. In 2015, along with the Grant agreement (the “Grant Agreement”), we concurrently entered into a Global Access Commitments Agreement with BMGF, under which we agreed to make a certain amount of the RSV F Vaccine available and accessible at affordable pricing to people in certain low and middle income countries.

Phase 2 Safety and Immunogenicity Trial (Completed)

In September 2015, we announced positive top-line data from ourinitiate Phase 2 clinical trial of our RSV F Vaccine in 50 healthy pregnant womenfor COVID-influenza combination vaccine and their infants. This clinical trial evaluated the safety and immunogenicity of our RSV F Vaccine in pregnant women in their third trimester, and assessed the transplacental transfer of maternal antibodies induced by the vaccine. The trial also examined the impact of maternal immunization on infant safety during the first year of life and RSV-specific antibody levels through the infants’ first six months of life. Immunized women demonstrated a geometric mean 14-fold rise in anti-F IgG, a 29-fold rise in palivizumab-competing antibodies and 2.7 and 2.1-fold rises in microneutralization titers against RSV/A and RSV/B, respectively. In contrast, women who received placebo demonstrated no significant change in antibody levels. The infants’ antibody levels at delivery averaged 90-100% of the mothers’ levels, indicating efficient transplacental transfer of antibodies from mother to infant. The estimated half-lives of infant PCA, anti-F IgG, and RSV/A and RSV/B microneutralizing antibodies, based on data through day 60, were 41, 30, 36 and 34 days, respectively.

Fast Track Designation

The FDA granted Fast Track designation to our RSV F Vaccine for protection of infants via maternal immunization. Fast Track designation is intended for products that treat serious or life-threatening diseases or conditions, and that demonstrate the potential to address unmet medical needs for such diseases or conditions. The program is designed to facilitate development and expedite review of drugs to treat serious and life-threatening conditions so that approved products can reach the market expeditiously.

RSV Older Adults Program

Burden of Disease

Older adults (60 years of age and older) are at increased risk for RSV disease due to immunosenescence, the age-related decline in the human immune system. In this population, RSV is an important respiratory virus, distinct from influenza, which is frequently responsible for serious lower respiratory tract disease and may lead to hospitalization or even death. Additionally, RSV infection can lead to exacerbation of underlying co-morbidities such as chronic obstructive pulmonary disease (“COPD”), asthma and congestive heart failure. In the U.S., the incidence rate is approximately 2.5 million infections per year, and RSV is increasingly recognized as a significant cause of morbidity and mortality in the population of 64 million older adults.11,12 Based on our analysis of published literature applied to 2014 U.S. population estimates, the disease causes 207,000 hospitalizations and 16,000 deaths among adults older than 65.13,14 Annually, we estimate that there are approximately 900,000 medical interventions directly caused by RSV disease across all populations.15,16

Clinical Trial Updates and Analyses

Phase 2 (E-205) Safety and Immunogenicity Clinical Trial (Completed)

In July 2017, we announced positive top-line data from our Phase 2 clinical trial of our RSV F Vaccine in older adults known as E-205. The objective of the E-205 trial was to assess safety and immunogenicity to one and two dose regimens of the RSV F Vaccine, with and without aluminum phosphate or our proprietary Matrix-M adjuvant, in older adults. The trial was a randomized, observer-blinded, placebo-controlled trial which enrolled 300 older adults in the Southern Hemisphere. Participants were enrolled and vaccinated outside of the RSV season to best assess immunogenicity. Immunogenicity results indicated both aluminum phosphate and Matrix-M adjuvants increased the magnitude, duration and quality of the immune response relative to RSV F antigen alone. All formulations and regimens were safe and well-tolerated. The data support the inclusion of adjuvanted formulations of our RSV F Vaccine in future older adult trials, although we do not currently expect to initiate such trials in 2018 without additional funding.

Further Analyses of Prior Clinical Trials

Following the September 2016 announcement of top-line results of Resolve™, our Phase 3 clinical trial of our RSV F Vaccine in older adults conducted during the 2015-16 RSV season in the U.S., we conducted multiple analyses on the clinical data from the Resolve trial, as well as the other completed Phase 2 clinical trials conducted in older adults. Our analyses of these clinical trials sought to better understand their results. More detailed descriptions of each of these RSV older adult clinical trials are found under “Clinical Trial Updates and Analyses” below; the trials are named and briefly described in the following table: 

Clinical Trial Name Phase Description Conducted Participants(#) 
E-201 Phase 2 Efficacy in prevention of all symptomatic RSV disease 2014-15 RSV season  1,600  
Resolve (or E-301) Phase 3 Efficacy in prevention of msLRTD 2015-16 RSV season  11,856  
E-202 Rollover Phase 2 Immunogenicity in response to serial immunization after E-201 2015-16 RSV season  1,329  
E-205 Phase 2 Immunogenicity in one or two doses, with or without adjuvant 2017  300  

We have found that seasonal variation in attack rate, meaning the incidence of infectious disease in an at-risk population, may have a large impact on demonstrating vaccine efficacy in a particular year. Lower attack rates may mean that either the virus is less common in a given season, or alternatively, that the population being studied has increased intrinsic resistance in that season due to a variety of potential factors such as recent prior exposure. In our E-201 trial, we witnessed a high attack rate and showed a clear demonstration of efficacy. In our Resolve trial the following year, we observed a primary endpoint attack rate of only one-fourth that of the previous season. This scenario represents a conundrum that influenza vaccine developers have experienced for decades: “low attack rate” influenza seasons make it very difficult to demonstrate vaccine efficacy.

Additional further analyses of the Resolve trial data indicate that our RSV F Vaccine was associated with a 61% reduction in hospitalizations due to COPD exacerbations, and the same analysis of the E-201 trial showed a similar signal, supporting this finding. We believe that such higher-risk patients represent an unmet medical need with a significant healthcare cost burden that could potentially be addressed by such a vaccine.

Resolve (E-301) Phase 3 Trial (Completed)

In September 2016, we announced top-line data from our Resolve trial. Resolve was a randomized, observer-blinded, placebo-controlled trial that began in November 2015, and was fully enrolled with 11,856 older adults at 60 sites in the U.S. by December 2015. The trial did not meet its pre-specified primary or secondary efficacy objectives and did not demonstrate vaccine efficacy. The primary objective of the Resolve trial was to demonstrate efficacy in the prevention of moderate-severe RSV (“msLRTD”), as defined by the presence of multiple lower respiratory tract symptoms. The secondary objective of the trial was to demonstrate efficacy of the RSV F Vaccine in reducing the incidence of all symptomatic respiratory disease due to RSV ARD. The trial also evaluated the safety of an unadjuvanted, 135 microgram dose of the RSV F Vaccine compared to placebo. Consistent with our previous clinical experience, the vaccine was well-tolerated.

Phase 2 (E-202) Rollover Trial (Completed)

In September 2016, we announced positive top-line data from our E-202 rollover trial of our RSV F Vaccine in older adults. The trial was a randomized, observer-blinded, placebo-controlled rollover trial, which enrolled 1,329 older adults from our prior E-201 trial, conducted at the same 10 sites in the U.S. as the E-201 trial. The primary objectives of the trial were to evaluate safety and serum anti-F IgG antibody concentrations in response to immunization with the RSV F Vaccine. The exploratory objectives of the trial evaluated the efficacy of a second annual dose of the RSV F Vaccine in the prevention of RSV ARD and RSV msLRTD. Participants previously randomized to receive 135 microgram RSV F Vaccine or placebo were re-enrolled and re-randomized to receive either 135 microgram RSV F Vaccine or placebo. This trial design resulted in four separate trial arms: a) participants receiving a placebo in both the first trial and second trial (“Placebo-Placebo”); b) participants receiving RSV F Vaccine in the first trial and placeboNanoFlu standalone in the second trial (“Vaccine-Placebo”); c) participants receiving placebo in the first trial and RSV F Vaccine in the second trial (“Placebo-Vaccine”); and d) participants receiving RSV F Vaccine in both the first trial and second trial (“Vaccine-Vaccine”).

The E-202 rollover trial demonstrated immunogenicity in all active vaccine recipients, with a 6-fold increase in anti-F IgG in the Placebo-Vaccine arm, consistent with the E-201 trial. There was higher anti-F IgG at baseline in the Vaccine-Vaccine arm compared to the Placebo-Vaccine arm and the Vaccine-Vaccine arm showed a greater than 2-fold increase in anti-F IgGhalf of 2022


Publication Highlights

Final analysis from the higher baseline.

PREVENT-19 Phase 2 (E-201) Trial in Older Adults (Completed)

In August 2015, we announced positive top-line data from our E-201 trial of our RSV F Vaccine in 1,600 older adults. The E-201 trial was designed to prospectively examine the incidence of all symptomatic respiratory illnesses associated with RSV infection, in community-living older adults who were treated with placebo. The trial also evaluated safety and immunogenicity of our RSV F Vaccine compared to placebo. Finally, the trial estimated the efficacy of our RSV F Vaccine in reducing the incidence of respiratory illness due to RSV. The trial was the first to demonstrate efficacy of an active RSV immunization in any clinical trial population. In the per protocol population, the clinical trial showed statistically significant vaccine efficacy in prevention of all symptomatic RSV disease (41%) and, in an ad hoc analysis, showed a decrease in RSV disease with any symptoms of lower respiratory tract infection (45%) in older adults. The clinical trial established an attack rate for symptomatic RSV disease of 4.9% in older adults, 95% of which included lower respiratory track symptoms. Efficacy against more severe RSV illness, defined by the presence of multiple lower respiratory tract symptoms or signs associated with difficulty breathing, was 64% in ad hoc analyses.

RSV Pediatrics Program

Burden of Disease

There are currently approximately 18 million children in the U.S. between six months and five years of age.17 By the age of five, essentially all children will have been exposed to RSV and will likely have developed natural immunity against the virus, thus decreasing the rate of severe disease in these children. In the U.S., RSV is responsible for approximately 57,000 hospitalizations of children under five years of age annually, the vast majority of which occur in infants less than one year old, and especially those under six months of age.18,19,20,21,22

Clinical Trial Update

In September 2015, we announced positive top-line data from our Phase 1 clinical trial of our RSV F Vaccine in healthy children between two and six years of age. This clinical trial evaluated the safety and immunogenicity of our RSV F Vaccine, with one or two doses, with or without aluminum phosphate adjuvant. Trial enrollment was concluded with a smaller than planned cohort so that dosing could be completed ahead of the 2014-15 RSV season. The vaccine was well-tolerated and serum samples collected from a subset of 18 immunized children in the per-protocol population, demonstrated that the RSV F Vaccine was highly immunogenic at all formulations and regimens. There were greater than 10-fold increases in both anti-F IgG and PCA antibody titers in the adjuvanted group and greater than 6-fold increases in anti-F IgG and PCA antibody titers in the unadjuvanted group. Development of our RSV F Vaccine for pediatrics would likely follow successful development of our RSV F Vaccine for maternal immunization.

Influenza

Burden of Disease

Influenza is a world-wide infectious disease that causes illness in humans ranging from mild to life-threatening symptoms or even death. Serious illness occurs not only in susceptible populations such as pediatrics and older adults, but also in the general population largely because of infection by unique strains of influenza for which most humans have not developed protective antibodies. Current estimates for seasonal influenza vaccine growth in the top seven markets (U.S., Japan, France, Germany, Italy, Spain and UK), show a potential increase from approximately $3.2 billion in the 2012-13 season to $5.3 billion by the 2021-22 season.23

The Advisory Committee for Immunization Practices of the Center for Disease Control and Prevention (“CDC”) recommends that all persons aged six months and older be vaccinated annually against seasonal influenza. Influenza is a major burden on public health worldwide: an estimated one million deaths each year are attributed to influenza.24 It is further estimated that, each year, influenza attacks between 5% and 10% of adults and 20% to 30% of children, causing significant levels of illness, hospitalization and death.25  One important advantage of recombinant seasonal influenza vaccines, like the candidate we are developing, is that once licensed for commercial sale, large quantities of such vaccine could potentially be manufactured quickly and in a cost-effective manner, without the use of either live influenza virus or eggs. Our recombinant influenza nanoparticles also can display conserved antigenic regions, which have the potential to elicit broadly neutralizing antibodies that appear to protect against a range of “drifted” strains, or influenza strains in which, over time, the hemagglutinin antigen undergoes an accumulation of genetic mutations at the hemagglutinin antigen sites that bind with neutralizing antibodies, potentially resulting in reduced protection of those antibodies. Additionally, nanoparticles offer improved purity and manufacturability and advantages for co-formulation with other nanoparticle-based vaccines.

Clinical Trial Update

In February 2018, we reported positive top-line results from our Phase 1/2 clinical trial of our nanoparticle seasonal influenza vaccine candidate, including our proprietary Matrix-M adjuvant (“NanoFlu™ vaccine”), in older adults that was initiated in September 2017. The trial was a randomized, observer-blinded, active comparator-controlled3 trial in approximately 330 healthy older adults. The primary objective of the trial was to assess the safety and immunogenicity of two concentrations (15 micrograms or 60 micrograms) of NanoFlu vaccine compared to the leading licensed egg-based, high-dose influenza vaccine for older adults (“IIV3-HD”). Key findings from the trial include that NanoFlu vaccine induced:

·Significantly higher hemagglutination inhibition (“HAI”) antibody responses against homologous H1N1 and H3N2 influenza viruses and comparable HAI responses against the homologous B/Brisbane strain;

·Significantly higher HAI immune responses against historic and forward-drifted H3N2 virus strains; and

·Strong neutralizing antibody responses that correlate with HAI results.

Overall, NanoFlu vaccine was well-tolerated over the three-week trial period. Given the strength of these trial results, we have submitted for publication in a peer-reviewed medical journal and/or for presentation at an upcoming scientific meeting. Based on these results, we expect to begin a Phase 2 trial of our NanoFlu vaccine in the third quarter of 2018.

Preclinical Analyses

Preclinical data in which NanoFlu was compared in a head-to-head challenge study against IIV3-HD, as well as IIV3-SD (standard dose) seasonal influenza vaccine, was announced in August 2017 and provided a strong rationale for the initiation of the Phase 1/2 trial. Our NanoFlu vaccine demonstrated significantly stronger and broader immune responses (microneutralizing antibodies) against homologous and heterologous influenza strains, including a series of drifted H3N2 strains evolved across over more than a decade of influenza seasons. In this preclinical challenge study, we showed that our NanoFlu vaccine was more protective than the licensed comparator vaccines against both a homologous H3N2 virus and a ten-year old drifted H3N2 strain. In parallel, we announced the achievement of significant improvements in manufacturing yields and product purity.

Emerging Viruses

Ebola Virus

EBOV, formerly known as Ebola hemorrhagic fever, is a severe, often fatal illness in humans. Multiple strains of EBOV have been identified, the most recent of which, the Makona EBOV strain, is associated with a case fatality rate of 50% to 90%.26 There are currently no licensed treatments proven to neutralize the virus, but a range of blood, immunological and drug therapies are under development. Despite the development of such therapies, current vaccine approaches target either a previous strain of the virus or were initially developed to be delivered by genetic vectors. In contrast, our EBOV glycoprotein vaccine candidate (“Ebola GP Vaccine”) was developed using the Makona EBOV strain.

26 WHO: http://www.who.int/mediacentre/factsheets/fs103/en/

45

In July 2015, we announced positive top-line data from our Phase 1 clinical trial of our Ebola GP Vaccine in ascending doses, with and without our Matrix-M adjuvant, in 230 healthy adults. Participants received either one or two intramuscular injections ranging from 6.5 micrograms to 50 micrograms of antigen, with or without adjuvant, or placebo. Immunogenicity was assessed at multiple time points, including days 28 and 35. These Phase 1 data demonstrated that our Ebola GP Vaccine is highly immunogenic, well-tolerated and, in conjunction with our proprietary Matrix-M adjuvant, resulted in significant antigen dose-sparing. The adjuvanted Ebola GP Vaccine was highly immunogenic at all dose levels; the adjuvanted two-dose regimens induced Ebola anti-GP antibody geometric mean responses between 45,000 and 70,000 ELISA units, representing a 500 to 750-fold rise over baseline at day 35. In 2015, we also announced successful data from two separate non-human primate challenge studies of our Ebola GP Vaccine in which, in both cases, the challenge was lethal for the control animal, whereas 100% of the immunized animals were protected.

Zika Virus

We initiated development of a vaccine against the Zika virus (“ZIKV”) in response to the unmet global medical need for a response to this serious disease. The subsequent evolving epidemiology of ZIKV, which saw significant reductions in cases both in the U.S. and around the worldMexico published in 2017, along with the uncertaintyThe New England Journal of governmental and non-governmental organization funding, has caused us to suspend these development efforts in lieu of competing resources and corporate priorities around more promising product development.

Combination Respiratory Vaccine

Given the ongoing development of our RSV F Vaccine and our desire to develop a combination respiratory vaccine with the potential to protect against both RSV and seasonal influenza, we made the decision to shift our seasonal influenza vaccine development focusMedicine


Final analysis from VLP-based seasonal influenza vaccines to nanoparticle-based seasonal influenza vaccines. We remain confident that a combination nanoparticle vaccine against both RSV and influenza is feasible.

CPLB Joint Venture (India)

CPL Biologicals Private Limited (“CPLB”), our joint venture company with Cadila Pharmaceuticals Limited (“Cadila”) in India, is actively developing a number of vaccine candidates that were genetically engineered by us. CPLB is owned 20% by us and 80% by Cadila. CPLB operates a manufacturing facility in India for the production of vaccines.

Seasonal Influenza

Since 2016, CPLB has been marketing CadiFlu-S, its trivalent VLP influenza vaccine in India, with limited sales in 2017 and expected in 2018.

Critical Accounting Policies and Use of Estimates

The discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements, which have been prepared in accordance with generally accepted accounting principles generally accepted in the United States.

U.S.

The preparation of our consolidated financial statements requires us to make estimates, assumptions, and judgments that affect the reported amounts of assets, liabilities, and equity and disclosure of contingent assets and liabilities atas of the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. These estimates, particularly estimates relating to accounting for revenue, the valuation of our marketable securities, stock-based compensation, long-lived assetslease accounting, pre-launch inventory, and goodwillaccounting for research and development expenses have a material impact on our consolidated financial statements and are discussed in detail throughout our analysis of the results of operations discussed below.

We base our estimates on historical experience and various other assumptions that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets, liabilities and equity that are not readily apparent from other sources. Actual results and outcomes could differ from these estimates and assumptions.

Revenue

Recognition

We perform research and development under government funding, grant, license and clinical development agreements. Our revenue primarily consists of funding under U.S. government contracts and other arrangements to advance the clinical
67

development and manufacturing of NVX-CoV2373. Our U.S. government contracts include the DoD Contract and the OWS Agreement. Other funding arrangements primarily include a grant and forgivable loan funding from CEPI.
At contract inception, we analyze our revenue arrangements to determine the appropriate accounting under generally accepted accounting principles in the United States (“U.S. GAAP”). Currently, our revenue arrangements represent customer contracts within the scope of Accounting Standards Codification (“ASC”) Topic 606, Revenue from Contracts with Customers (Topic 606) (“ASC 606”) or are subject to the contribution guidance in ASC Topic 958-605, Not-for-Profit Entities – Revenue Recognition (“ASC 958-605”), which applies to business entities that receive contributions within the scope of ASC 958-605. We recognize revenue under researchfrom arrangements within the scope of ASC 606 following the five-step model: (i) identify the contract(s) with a customer; (ii) identify the performance obligation(s) in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) we satisfy a performance obligation. We only apply the five-step model to contracts when a contract hasit is probable that we will collect the consideration we are entitled to in exchange for the goods or services we transfer to our customer. We recognize contribution revenue within the scope of ASC 958-605 when the funder-imposed conditions have been executed, the contract price is fixed or determinable, delivery of services or products has occurred and collection of the contract price is reasonably assured. Payments received in advance of work performedsubstantially met. Contributions are recorded as deferred revenue until the period in which research and lossesdevelopment activities are performed that satisfy the funder-imposed conditions.
Under our U.S government contracts, we are entitled to receive funding, on a cost-reimbursable or cost-reimbursable-plus-fixed-fee basis, to support certain activities related to the development, manufacture, and delivery of NVX-CoV2373 to the U.S. government. We analyzed these contracts and determined that they are within the scope of ASC 606. Our obligations under each of the contracts are not distinct in the context of the contract as they are highly interdependent or interrelated and, as such, they are accounted for as a single performance obligation. The transaction price under these arrangements is the consideration we expect to receive and consists of the funded contract amount and the unfunded variable amount to the extent that it is probable that a significant reversal of revenue will not occur. We recognize revenue for these contracts over time as we transfer control over the goods and services and satisfy our performance obligation. We measure progress toward satisfaction of our performance obligation using an Estimate-at-Completion (“EAC”) process, which is a cost-based input method that reviews and monitors the progress towards the completion of our performance obligation. Under this process, we consider the costs that have been incurred to-date, as well as projections to completion using various inputs and assumptions, including, but not limited to, progress towards completion, labor costs and level of effort, material and subcontractor costs, indirect administrative costs, and other identified risks. Estimating the total allowable cost at completion of our performance obligation under a contract is subjective and requires us to make assumptions about future activity and cost drivers. Changes in these estimates can occur for a variety of reasons and, if any,significant, may impact the timing of revenue and fee recognition on our contracts. Allowable contract costs include direct costs incurred on the contract and indirect costs that are applied in the form of rates to the direct costs. Progress billings under the contracts are initially based on provisional indirect billing rates, agreed upon between us and the U.S. government. These indirect rates are subject to review on an annual basis. The impact of changes in the indirect billing rates are recorded in the period when such changes are identified and reflect the difference between actual indirect costs incurred compared to the estimated amounts used to determine the provisional indirect billing rates agreed upon with the U.S. government. We recognize revenue on our U.S government contracts based on reimbursable allowable contract costs incurred in the period up to the transaction price. For our cost-reimbursable-plus-fixed-fee contracts, we recognize the fixed fee based on the proportion of reimbursable contract costs incurred to total estimated allowable contract costs expected to be incurred on completion of the underlying performance obligation as determined under the EAC process. Changes in estimates related to the EAC process are recognized in the period when such changes are made on a cumulative catch-up basis. We include the transaction price comprising both funded and unfunded portions of customer contracts, in which they become known.

this estimate. We have historically performed researchnot experienced any material difference as a result of change in estimate arising from the EAC process.

Our other funding arrangements primarily include the CEPI Grant Funding and developmentCEPI Forgivable Loan Funding (each as defined in “Note 2―Summary of Significant Accounting Policies” included in our Notes to Consolidated Financial Statements). The CEPI Forgivable Loan Funding is designated for U.S. Government agencies under cost reimbursable fixed-fee contracts. Under such cost reimbursable fixed-fee contracts, we were reimbursedthe prepayment of certain manufacturing activities. We analyzed these other funding arrangements and recognized revenuedetermined that they are not within the scope of ASC 606 as allowable costs were incurred plusthey do not provide a portion of the fixed-fee earned. We consider fixed-fees under cost reimbursable contracts to be earned in proportiondirect economic benefit to the allowable costs incurred in performance of the work as compared to total estimated contract costs, with such costs incurred representing a reasonable measurement of the proportional performance of the work completed. Under our HHS BARDA contract, certain activities were pre-approved by HHS BARDA in order for their costs to be deemed allowable direct costs. Direct costs incurred under cost reimbursable contracts are recorded as research and development expenses. Payments to us under cost reimbursable contracts, such as the HHS BARDA contract, are provisional payments subject to adjustment upon audit by the government. An audit of indirect rates by the U.S. government for the years ended December 31, 2011 and 2012 was completed in the first quarter of 2014, which resulted in $7.7 million revenue recognized in 2015 relating to the recovery of additional costs for the settlement of indirect rates for such years as collection of the amount became reasonably assured. An audit of indirect rates for the years ended December 31, 2013 and 2014 was completed in the first quarter of 2017. When the final determination of the additional costs for the years ended December 31, 2013 and 2014 has been made, and such amount is known and collection of the amount is reasonably assured, revenue and billings will be adjusted accordingly.

Under our Grant Agreement with BMGF, we are reimbursed for certain costs that support development activities, including our global Phase 3 clinical trial in pregnant women in their third trimester, product licensing efforts and efforts to obtain WHO prequalification of our RSV F Vaccine.grantor. Payments received under the Grant Agreementgrant funding arrangements are considered conditional contributions under the scope of ASC 958-605 and are recorded as deferred and recognized as revenue whenuntil the period in which such research and development activities are performed.actually performed that satisfy the funder-imposed conditions. Payments received under the CEPI Forgivable Loan Funding are only repayable if the proceeds of sales to one or more third parties of NVX-CoV2373 cover our costs of manufacturing such vaccine candidate, not including manufacturing costs funded by CEPI. As the financial risk remains with CEPI, we have determined that the use of the CEPI Forgivable Loan Funding is outside the scope of ASC Topic 470, Debt. The research and development risk is considered substantive, such that it was not probable that the development would be successful at the inception of the contract. Therefore, we have concluded that ASC Topic 730, Research and Development is considered applicable and most appropriate. Given the financial risk associated with the research and development activities lies with CEPI because repayment of any funds provided by CEPI depends solely on the results of the research and development activities having future economic benefit, we account for our obligation under the CEPI Forgivable

Loan Funding as a contract to perform research and development for others. We analyze grant agreements to determine whether thehave determined that payments received under these agreements should be recorded as revenue or asunder ASC 958-605 rather than a reduction to research and development expenses. This is consistent with our policy of presenting such amounts as revenue. In reaching this determination, management considerswe considered a number of factors, including whether we are the principal under the arrangement, and whether the arrangement is significant to, and part of, our core operations. Historically,We will record revenue as we perform the contractual research and development services.
We have manufacturing and supply arrangements that include a license to use our intellectual property.The licensing arrangements include sales-based royalties, certain development and commercial milestone payments, receivedand the sale of proprietary Matrix-MTM adjuvant. The license is deemed to be the predominant item to which the milestone payments and sales-based royalties relate. Because development milestone payments are contingent on the achievement of milestones that are not within our control or the control of the licensee, such as regulatory approvals, the payments are not considered probable of being achieved and are excluded from the transaction price until the milestone is achieved. We recognize revenue when the development milestone is achieved. For arrangements that include sales-based royalties, including milestone payments based upon the achievement of a certain level of product sales, wherein the license is deemed to be the sole or predominant item to which the payments relate, we recognize revenue on the satisfaction (or partial satisfaction) of the performance obligation to which some or all of the payment has been allocated, which is normally when the related sales occur.

We generally allocate the transaction price to each performance obligation based on a relative standalone selling price basis. We develop assumptions that require judgment to determine the standalone selling price for each performance obligation in consideration of applicable market conditions and relevant entity-specific factors, including factors that were contemplated in negotiating the agreement with the customer.

Lease Accounting

We enter into manufacturing supply agreements with CMOs and CDMOs to manufacture our vaccine candidates. Certain of these manufacturing supply agreements include the use of identified manufacturing facilities and equipment that are controlled by us and for which we obtain substantially all the output and may qualify as an embedded lease. We treat manufacturing supply agreements that contain a lease as lease arrangements in their entirety. The evaluation of leases that are embedded in our CMO and CDMO agreements is complex and requires judgment in determining whether the contract, either explicitly or implicitly, is for the use of an identified asset, which generally is the use of a portion of the manufacturing facility, whether we have the right to direct the use of, and obtain substantially all of the benefit from, the identified asset, the term of the lease and the fixed lease payments under grant agreements have been recognizedthe contract. Depending on the contract, the lease commencement date, defined as revenue sincethe date on which the lessor makes the underlying asset available for use by the lessee and is the date on which the Company is required to accrue lease expenses, may be different than the inception date of the contract. We determine the non-cancellable lease term of our embedded leases based on the impact of certain expected milestones on our option to terminate the lease where we act asare reasonably certain to not exercise that option. We evaluate changes to the terms and conditions of a principallease contract to determine if they result in a new lease or a modification of an existing lease. For lease modifications, we remeasure and reallocate the remaining consideration in the arrangementcontract and reassess the activities are core to our operations.

Revenue associated with upfront payments under arrangements is recognized overlease classification at the contract term or when all obligations associated with the upfront payment have been satisfied.

Marketable Securities

Our marketable securities are classified as available-for-sale securities and are carried at fair value. Unrealized gains and losses on these securities, if determined not to be “other-than-temporary,” are included in accumulated other comprehensive income (loss) in stockholders’ deficit. Investments are evaluated periodically to determine whether a decline in value is “other-than-temporary.” Management reviews criteria, such as the magnitude and durationeffective date of the decline,modification. We classify leases as well aseither operating or finance leases based on the Company’s abilityeconomic substance of the agreement. We also enter into non-cancelable lease agreements for facilities and certain equipment.


For leases that have a lease term of more than 12 months at the lease commencement date, we recognize lease liabilities, which represent our obligation to holdmake lease payments arising from the securities until market recovery,lease, and corresponding right-of-use (“ROU”) assets, which represent the right to predict whetheruse an underlying asset for the loss in value is other-than-temporary. If a decline in value is determined to be other-than-temporary,lease term, based on the present value of the security is reduced andfixed future payments over the impairment is recordedlease term. We calculate the present value of future payments using the discount rate implicit in the statementslease, if available, or our incremental borrowing rate. For all leases that have a lease term of operations. For marketable securities carried12 months or less at fair value,the commencement date (referred to as “short-term” leases), we disclosehave elected to apply the level within the fair value hierarchy as prescribed by Accounting Standard Codification (“ASC”) Topic 820,Fair Value Measurements and Disclosures. We evaluate the types of securitiespractical expedient in our investment portfolio to determine the proper classification in the fair value hierarchy based on trading activity and market inputs. We generally obtain information from an independent third-party to help us determine the fair value of securities in Level 2 of the fair value hierarchy. Investment income is recorded when earned and included in investment income.

Stock-Based Compensation

We account for our stock-based compensation under our equity compensation plans in accordance with ASC Topic 718,Compensation-Stock Compensation. This standard requires us842, Leases (“ASC 842”) to measure the cost of employee services received in exchange for equity awards based on the grant-date fair value of the award. Employee stock-based compensation is estimated at the date of grant based on the award’s fair value using the Black-Scholes option-pricing model and is recognizednot recognize a lease liability or ROU asset but instead, recognize lease payments as an expense on a straight-line basis over the requisite servicelease term and variable lease payments that do not depend on an index or rate, as an expense in the period in which the variable lease costs are incurred based on performance or usage in accordance with contractual agreements. In determining the lease period, we evaluate facts and circumstances that could affect the period over which we are reasonably certain to use the underlying asset while taking into consideration the non-cancelable period over which we have the right to use the underlying asset and any option period to extend or terminate the lease if we are reasonably certain to exercise the option. We re-evaluate short-term leases that are modified and if they no longer meet the requirements to be treated as a short-term lease, we recognize and measure the lease liability and ROU asset as if the date of the modification is the lease commencement date (see Note 7 to the accompanying consolidated financial statements). For short-term leases that are modified and continue to meet the requirements to be treated as a short-term lease, we remeasure the fixed lease payments under the modified lease, and recognize lease payments as an expense on a straight-line basis over the modified lease term.


For operating leases, we recognize lease expense related to fixed payments on a straight-line basis over the lease term and lease expense related to variable payments as incurred based on performance or usage in accordance with the contractual agreements. For finance leases, we recognize the amortization of the ROU asset over the shorter of the lease term or useful life
69

of the underlying asset. We expense ROU assets acquired for those awards expectedresearch and development activities under ASC Topic 730, Research and Development,if they do not have an alternative future use, in research and development projects or otherwise.

We use significant assumptions and judgment in evaluating our lease contracts and other agreements under ASC 842, including the determination of whether an agreement is or contains a lease, whether a change in the terms and conditions of a lease contract represent a new or modified lease, whether a lease represents an operating or finance lease, the discount rate used to vest. The Black-Scholes option-pricing model requiresdetermine the present value of lease obligations and the term of embedded leases in our manufacturing supply agreements.
Pre-Launch Inventory
Prior to an initial regulatory authorization for our product candidates, we expense costs relating to raw materials and inventory production as research and development expenses in our consolidated statements of operations in the period incurred. We capitalize the costs of production as inventory when we believe regulatory authorization and subsequent commercialization is considered probable and we expect to realize future economic benefit from the sales of the product candidate.
Upon the authorization of distribution and use of certain assumptions,NVX-CoV2373 following regulatory authorization by EMA and the most significantWHO in December 2021, we began to capitalize inventory costs associated with the related supply of NVX-CoV2373, as it was determined that inventory costs subsequently incurred had a probable future economic benefit.
Accounting for Research and Development Expenses
We estimate our prepaid and accrued expenses related to our research and development activities using a process that involves reviewing contracts and purchase orders, communicating with our project managers and service providers to identify services that have been performed on our behalf, and estimating the level of service performed and the associated cost incurred for the service when we have not yet been invoiced or for which arewe have been invoiced in advance of the service. This estimation process includes a review of:
expenses incurred under agreements with contract research organizations (“CROs”) that conduct our clinical trials and third party consultants; and
the cost of developing and manufacturing vaccine components under third-party CMOs and CDMOs agreements, including expenses incurred for the procurement of raw materials, laboratory supplies and equipment.
We base our expenses on our estimates of the expected volatilityservices provided and efforts expended pursuant to contracts, statements of work and related change orders with the service provider, as well as discussion with internal personnel and external service providers as to the progress of the market price of our common stockservices and the expected termagreed-upon fee to be paid for such services. The financial terms of these agreements are based on negotiated terms, vary from contract to contract and may result in an uneven level of activity over time. There may be instances in which payments made to our vendors will exceed the level of services provided and result in a prepayment of the award. Our estimateexpense. Additionally, invoicing from third-party service providers may not coincide with actual work performed and can result in a prepaid or an accrual position at the end of the expected volatility is based on historical volatility overperiod. The estimation process requires us to make significant judgments and estimates in determining the look-back period correspondingservices incurred as of the balance sheet date, which may result in either a prepaid or an accrual balance. As actual costs become known, we adjust our estimates. Although we do not expect our estimates to be materially different from amounts actually incurred, our understanding of the status and timing of services performed may vary from the related estimates and could result in us reporting amounts that are too high or too low in a particular period. Our prepaid and accrued expenses are dependent, in part, upon the receipt of timely and accurate reporting from CROs, CMOs, CDMOs, and third-party service providers. Due to the expected term. The expected term represents the period during which our stock-based awards are expected to be outstanding. We estimate this amount based on historical experience of similar awards, giving consideration to the contractual termsnature of the awards, vesting requirementsestimation process, there may be a difference between estimated costs and expectation of future employee behavior, including post-vesting exercise and forfeiture history. We review our valuation assumptions at each grant date and, as a result, our assumptionsactual costs incurred. Historically, we have not experienced any material differences in future periods may change. Also, the accounting estimate of stock-based compensation expense is reasonably likely to change from period to period as further equity awards are made and adjusted for cancellations.

Impairments of Long-Lived Assets

We account for the impairment of long-lived assets (including finite-lived intangible assets) by performing an evaluation of the recoverability of the carrying value of long-lived asset (group) whenever events or changes in circumstances indicate that the carrying value of the asset (group) may not be recoverable. Examples of events or changes in circumstances that indicate that the recoverability of the carrying value of an asset (group) should be assessed include, but are not limited to, the following: a significant decrease in the market value of an asset, a significant change in the extent or manner in which an asset is used, a significant physical change in an asset, a significant adverse change in legal factors or in the business climate that could affect the value of an asset, an adverse action or assessment by a regulator, an accumulation of costs significantly in excess of the amount originally expected to acquire or construct an asset, a current period operating or cash flow loss combined with a history of operating or cash flow losses and/or a projection or forecast that demonstrates continuing losses associated with an asset used for the purpose of producing revenue. We consider historical performance and anticipated future results in our evaluation of potential impairment. Accordingly, when indicators of impairment are present, we evaluate the carrying value of these assets (group) in relation to the operating performance of the business and future undiscounted cash flows expected to result from the use of these asset (groups). Impairment losses are recognized when the sum of expected future cash flows is less than the assets’ (group’s) carrying value.

Goodwill

Goodwill is subject to impairment tests annually or more frequently should indicators of impairment arise. The Company has determined since its only business is the development of recombinant vaccines that it operates as a single operating segment and has one reporting unit. The Company primarily utilizes the market approach and, if considered necessary, the income approach to determine if it has an impairment of its goodwill. The market approach is based on market value of invested capital. To ensure that the Company’s capital stock is the appropriate measurement of fair value, the Company considers factors such as its trading volume, diversity of investors and analyst coverage. If considered necessary, the income approach is used as a confirming look to the market approach. Goodwill impairment may exist if the carrying value of the reporting unit exceeds its estimated fair value. If the carrying value of the reporting unit exceeds its fair value, step two of the impairment analysis is performed. In step two of the analysis, an impairment loss is recorded equal to the excess of the carrying value of the reporting unit’s goodwill over its implied fair value, should such a circumstance arise.

At December 31, 2017 and 2016, the Company used the market approach to determine if the Company had an impairment of its goodwill. The fair value of the Company’s single reporting unit was substantially higher than its carrying value, resulting in no impairment to goodwill at December 31, 2017 and 2016.

The increaseand $217 million, respectively, related to the acceleration of manufacturing costs for leases that we determined were embedded in multiple manufacturing supply agreements with CMOs and CDMOs.

expenses incurred on developing and development manufacturing the antigen drug substance and Matrix-Madjuvant components of NVX-CoV2373 under agreements that we established with third-party CMOs and CDMOs;

expenses by the type of costs incurred in identifying, developing, manufacturing and testing vaccine candidates. We evaluate and prioritize our activities according to functional area and therefore believe that project-by-project information would not form a reasonable basis for disclosure to our investors. Historically, we did not account for internal research and development expenses by project, since our employees’ work time is spread across multiple programs and our internal manufacturing clean-room facility produces multiple vaccine candidates.

The following summarizes our research and development expenses by functional area for the years ended December 31, 2017, 2016procurement of raw materials, laboratory supplies, and 2015 (in millions).

equipment; and


other costs related to preclinical studies and regulatory consulting, as well as related program management activities to support our growing global operations.
We do not provide forward-looking estimates of costs and time to complete our research programs due to the many uncertainties associated with vaccine development. As we obtain data from preclinical studies and clinical trials, we may elect to discontinue or delay clinical trials in order to focus our resources on more promising vaccine candidates. Completion of clinical trials may take several years or more, but the length of time can vary substantially depending upon the phase, size of clinical trial, primary and secondary endpoints, and the intended use of the vaccine candidate. The cost of clinical trials may vary significantly over the life of a project as a result of a variety of factors, including:

·the number of participants who participate in the clinical trials;
·the number of sites included in the clinical trials;
·if clinical trial locations are domestic, international or both;
·the time to enroll participants;
·the duration of treatment and follow-up;
·the safety and efficacy profile of the vaccine candidate; and
·the cost and timing of, and the ability to secure, regulatory approvals.

As a result of these uncertainties, we are unable to determine with any significant degree of certainty the duration and completion costs of our research and development projects or when, and to what extent, we will generate future cash flows from our research projects.

For 2022, we expect total research and development expenses to decrease significantly as compared to 2021. The decline in 2022 is anticipated to result from expected capitalization of manufacturing costs during 2022 that were previously recognized as research and development expenses in prior periods, partially offset by research and development expenses related to increased clinical activities as we continue to develop our NVX-CoV2373 and other programs. Our cost of goods sold expenses could be significant depending on our commercial shipment levels and timing of deliveries. However, we anticipate initially recognizing a lower cost of goods sold expense as a result of pre-launch inventory previously recognized as research and development expenses.

General and Administrative Expenses


General and administrative expenses decreasedincreased to $34.5$298.4 million for 20172021 from $46.5$145.3 million for 2016, a decrease2020, an increase of $12.1 million, or 26%.$153.1 million. The decrease wasincrease in general and administrative expenses is primarily due to lowerincreased employee-related costs, including stock-based compensation expense, and an increase in professional fees including for pre-commercialization activities, and lower employee-related costs, as compared to 2016. At December 31, 2017, we had 48 employees dedicated to general and administrative functions versus 53 employees asin support of December 31, 2016. our NVX-CoV2373 program.

For 2018,2022, we expect general and administrative expenses to increase primarilysignificantly as compared to 2021 due to higher anticipated employeeincreased activities related to supporting our NVX-CoV2373 program and increases in employee-related costs and professional fees.

General We also expect to incur selling and administrativemarketing expenses increased to $46.5 million for 2016 from $30.8 million for 2015, an increasefollowing regulatory authorizations, and potential approvals, of $15.7 million, or 51%. The increase in general and administrative expenses was primarily due to higher employee-related costs driven by the administrative requirements needed to support our expanding research and development activities, and professional fees for pre-commercialization activities.

Liquidity Matters and Capital Resources

73

Our future capital requirements depend on numerous factors including, but not limited to, our projected activities related to the development of NVX-CoV2373, including significant commitments under various CRO, CMO and progress of our research and development programs,CDMO agreements, the progress of preclinical studies and clinical testing,trials, the time and costs involved in obtaining regulatory approvals, the costs of filing, prosecuting, defending and enforcing patent claims and other intellectual property rights and other manufacturing, sales and distribution costs. We plan to continue to have multipledeveloping other vaccines and product candidates, such as our NanoFlu vaccine candidate and potential combination vaccines candidates, which are in various stages of development, and wedevelopment. We believe our operating expenses and capital requirements will fluctuate depending upon the timing of events, such as the progress of our NVX-CoV2373 clinical trials and regulatory approval for the use of NVX-CoV2373 in the U.S. and internationally, as well as the scope, initiation rate and progress of our preclinical studies and clinical trials andrelated to other research and development activities.
We have entered into APAs or supply agreements with Gavi, the EC, and various countries globally. We also have grant and license agreements. As of December 31, 2021, the aggregate amount of the transaction price allocated to performance obligations that were unsatisfied (or partially unsatisfied), excluding amounts related to sales-based royalties under the licensing agreements, was approximately $8 billion. The timing to fulfill performance obligations related to grant agreements will depend on the results of our research and development activities, including clinical trials. The timing to fulfill performance obligations related to APAs will depend on timing of product manufacturing, delivery, and receipt of marketing authorizations. The remaining unfilled performance obligations are expected to be fulfilled in less than one year. The APAs or supply agreements typically contain terms that include upfront payments intended to assist us in funding investments related to building out and operating our manufacturing and distribution network, among other expenses, in support of our global supply commitment. Such upfront payments generally become non-refundable upon our achievement of certain development and commercial milestones. However, certain of the APAs and supply agreements may be terminated by the counterparty if we do not timely achieve requisite regulatory approval for NVX-CoV2373 in the relevant jurisdictions under such agreements. If the APAs or supply agreements were terminated, the refundable portion of the upfront payments will be repaid. We expect to sign additional APAs or supply agreements that are currently in active discussions and negotiations.
In May 2021, we finalized an APA with Gavi, building upon our MOU previously announced in February 2021. Under the terms of the agreement, 1.1 billion doses of NVX-CoV2373 are to be made available to countries participating in the COVAX Facility, which was established to allocate and distribute vaccines equitably to participating countries and economies. We expect to manufacture and distribute 350 million doses of NVX-CoV2373 to countries participating under the COVAX Facility. Under a separate purchase agreement with Gavi, SIIPL is expected to manufacture and deliver the balance of the 1.1 billion doses of NVX-CoV2373 for low- and middle-income countries participating in the COVAX Facility. We expect to deliver doses with antigen and adjuvant manufactured at facilities directly funded by the investments previously received from CEPI. In October 2021, we entered into a supply agreement and a contract development manufacturing agreement with SIIPL and SLS under which SIIPL and SLS will supply us with NVX-CoV2373. We expect to deliver doses with antigen and adjuvant manufactured at facilities directly funded under the funding agreement with CEPI, with initial doses supplied by SIIPL and SLS under the supply agreement. We expect to supply significant doses that Gavi would allocate to low-, middle- and high-income countries, subject to certain limitations, utilizing a tiered pricing schedule and Gavi may prioritize such doses to low- and middle- income countries, at lower prices. Additionally, we may provide additional doses, to the extent available from CEPI-funded manufacturing facilities, in the event that SIIPL cannot materially deliver expected vaccine doses to the COVAX Facility. Together with SIIPL, we expect to initiate delivery of doses following receipt of appropriate regulatory authorizations. Under the APA, we received an upfront payment of $350 million from Gavi in 2021 and recorded a receivable as of December 31, 2021, for an additional $350 million because the Company secured EUL for NVX-CoV2373 by the WHO in December 2021, which are recorded as deferred revenue.
We have also entered into supply and license agreements with strategic partners to supply NVX-CoV2373 in their specified territories under which we are entitled to receive royalties primarily from the sale of NVX-CoV2373 by our partners, such as SIIPL in India, Takeda in Japan, and SK bioscience in the Republic of Korea. During 2021, we received royalties of $195.8 million under these licensing arrangements.
We funded our operations in 2021 with cash and marketable securities on hand, upfront payments under APAs, and proceeds from the sale of common stock, in equity offerings,together with revenue under the issuance of convertible debtOWS Agreement and CEPI Funding Agreement that support our NVX-CoV2373 vaccine development activities. We anticipate our future operations to be funded by our cash, cash equivalents and marketable securities, upfront payments under our APAs and revenue under our former contractOWS Agreement, and, following receipt of global regulatory authorizations, and potential approvals, revenue from product sales, royalties under licensing arrangements with HHS BARDA and our current Grant Agreement with BMGF.

Our financing activities consisted primarily of sales of our common stock issuance of Notes,under our At Market Issuance Sales Agreements, finance lease payments related to embedded leases and, to a much lesser extent, stock option exercises of stock-based awards and purchases under our employee stock purchase plan. In 2017,2021, we received net proceeds of $63.4approximately $565 million from the sale of shares of common stock through our At Market Issuance Sales Agreements. In 2020, we received net proceeds of approximately $877 million (this amount excludes $3.2 million received in the first quarter of 2021 for shares traded in late December 2020) from selling shares of common stock through our January 2017 Sales Agreement at a weighted average sales price of $1.27 per share. From January 1, 2018 through March 9, 2018, we sold an additional 19.4 million shares of commons stock through both our January 2017 and December 2017various At Market Issuance Sales Agreements resulting in$36.3 million in net proceeds. In 2016, we received net proceeds of $276.5and approximately $200 million through the issuance of our Notes and payments of capped call transactions (see Note 9 to the consolidated financial statements included herewith).

In August 2015, we amended the lease for our facility located in Gaithersburg, Maryland to increase the amount of space leased by us to include the entire facility. Under the terms of the amended lease, the landlord provided us with a tenant improvement allowance of $3.9 million, which was fully funded at December 31, 2017. In May 2016, we entered into a new lease for a facility located in Gaithersburg, Maryland and under the terms of the lease the landlord provided us with a tenant improvement allowance of up to $9.6 million, and $1.2 million was funded at December 31, 2017. In January 2018, this new lease was terminated and we paid a termination fee to the landlord of $5.3 million in the first quarter of 2018, which we believe is less than the potential total lease and operating expense cash obligations that could have been incurred over one year.

In 2007, we entered into an agreement to license certain rights from Wyeth. The Wyeth license is a non-exclusive, worldwide license to a family of patents and patent applications covering VLP technology for use in human vaccines in certain fields, with expected patent expiration in early 2022. The Wyeth license provides for us to make an upfront payment (previously made), ongoing annual license fees, sublicense payments, milestone payments on certain development and commercialization activities and royalties on any product sales. Except in certain circumstances in which we continuously market multiple productspreferred stock in a country within the same vaccine program, the milestone payments are one-time only payments applicable to each related vaccine program. At present, CPLB’s recombinant trivalent seasonal VLP influenza vaccine (“CadiFlu”) is the only program to which the Wyeth license applies. The license may be terminated by Wyeth only for cause and may be terminated by us only after we have provided ninety (90) days’ notice that we have absolutely and finally ceased activity, including through any affiliate or sublicense, related to the manufacturing, development, marketing or sale of products covered by the license. In September 2015, we amended the license agreement with Wyeth. Among other things, the amendment restructured the $3 million milestone payment (“Milestone”) owed as a result of CPLB’s initiation of a Phase 3 clinical trial for CadiFlu in 2014. Under the amendment, the milestone payment, which has increased slightly over time, became due on December 31, 2017. The amendment also restructured the final milestone payment to apply to the initial seasonal influenza VLP vaccine candidate being developed outside India. Thus, the aggregate milestone payments for a seasonal influenza VLP vaccine candidate developed and commercialized was increased from $14 million to up to $15 million. In connection with the execution of the amendment, we agreed to pay a one-time only payment to Wyeth. The amendment also increased annual license maintenance fees associated with VLP vaccine candidates from $0.2 million to $0.3 million per year. Payments under the agreement to Wyeth as of December 31, 2017 aggregated $7.6 million. At December 31, 2017, the Milestone is recorded in accrued expenses on the consolidated balance sheet and is expected to be paid in the first quarter of 2018. The Milestone was recorded as a research and development expense in 2014.

Based on our most recent cash flow forecast, we believe our current capital, along with anticipated revenue under the Grant Agreement, is sufficient to fund our operating plans for a minimum of twelve months from the date that this Annual Report was filed. Additional capital may be required in the future to develop our vaccine candidates through clinical development, manufacturing and commercialization. We plan to meet such near term capital requirements primarily through cash and investments on hand, and a combination of equity and debt financings, collaborations, strategic alliances and marketing distribution or licensing arrangements and in the longer term, from revenue related to product sales, to the extent our product candidates receive marketing approval and can be commercialized. Our ability to obtain additional capital in the near term will likely be subject to various factors, including our ability to perform and thus generate revenue under the Grant Agreement, our overall business performance and market conditions.

Any capital raised by an equity offering or convertible securities has the potential to be substantially dilutive to the existing stockholders and any collaborations, strategic alliances and marketing distribution or licensing arrangements may require us to give up some or all rights to a product or technology at less than its full potential value. There can be no assurances that new financing will be available to us on commercially acceptable terms, if at all. If we are unable to perform under the Grant Agreement or obtain additional capital, we will assess our capital resources and may be required to delay, reduce the scope of, or eliminate one or more of our product research and development programs, and/or downsize our organization, including our general and administrative infrastructure.

The primary objective

Item 7A.    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We are subject to certain risks that may affect our results of operations, cash flows and fair values of assets and liabilities, including volatility in foreign currency exchange rates and interest rate movements.

Foreign Currency Exchange Risk

Although we are headquartered in the U.S. where we conduct the vast majority of our investmentbusiness activities, our results of operations are subject to foreign currency exchange rate fluctuations, including our foreign subsidiaries’ operations. We have two foreign consolidated subsidiaries, Novavax AB, which is preservationlocated in Sweden, and Novavax CZ, which is located in the Czech Republic.

While the financial results of capital, withour global activities are reported in U.S. dollars, the secondary objectivefunctional currency for our foreign subsidiaries is their respective local currency. Fluctuations in the foreign currency exchange rates of maximizing income. Asthe countries in which we do business will affect our operating results, often in ways that are difficult to predict. A 10% decline in the exchange rate between the U.S. dollar and Swedish Krona would result in a decline of stockholders’ equity (deficit) of approximately $4 million as of December 31, 2017, we had cash2021. A 10% decline in the exchange rate between the U.S. dollar and cash equivalentsCzech Koruna would result in a decline of $106.3stockholders’ equity (deficit) of approximately $4 million marketable securitiesas of $51.0 million, all of which are short-term in nature, and working capital of $129.6 million.

December 31, 2021.


Interest Rate Risk
Our exposure to marketinterest rate risk is primarily confined to our investment portfolio. As of December 31, 2017, our investments were classified as available-for-sale. We do not believe that a change in the market rates of interest would have any significant impact on the realizable value of our investment portfolio. Changes in interest rates may affect the investment income we earn on our marketable securities when they mature and the proceeds are reinvested into new marketable securities and, therefore, could impact our cash flows and results of operations.

Interest and dividend income is recorded when earned and included in investment income. Premiums and discounts, if any, on marketable securities are amortized or accreted to maturity and included in investment income. The specific identification method is used in computing realized gains and losses on the sale of our securities.

We are headquartered in the U.S. where we conduct the vast majority of our business activities. We have one foreign consolidated subsidiary, Novavax AB, which is located in Sweden. A 10% decline in the exchange rate between the U.S. dollar and Swedish Krona would result in a decline of stockholders’ deficit of approximately $2.9 million at December 31, 2017.

Our Notes have a fixed interest rate and we have no additional material debt. As such, we do not believe that we are exposed to any material interest rate risk as a result of our borrowing activities.

Evaluation of Disclosure Controls and Procedures

The term “disclosure controls and procedures” (defined in SEC Rule 13a-15(e)) refers to the controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files under the Securities Exchange Act of 1934 (the “Exchange Act”) is recorded, processed, summarized and reported, within time periods specified in the rules and forms of the Securities and Exchange Commission. “Disclosure controls and
76

procedures” include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, including its principal executive and financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.

The Company’s management, with the participation of the chief executive officer and the interim chief financial officer, has evaluated the effectiveness of the Company’s disclosure controls and procedures as of the end of the period covered by this Annual Report on Form 10-K (the “Evaluation Date”). Based on that evaluation, the Company’s chief executive officer and interim chief financial officer have concluded that, as of the Evaluation Date, such controls and procedures were effective at the reasonable assurance level.

Management’s Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting is defined in Rules 13a-15(f) and 15d-15(f) promulgated under the Exchange Act, as a process designed by, or under the supervision of, the Company’s principal executive officer and principal financial officer and effected by the Company’s board of directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles generally accepted in the United States (“GAAP”). Such internal control includes those policies and procedures that:

·pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the assets of the Company;
·provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with GAAP, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company; and
·provide reasonable assurance regarding prevention or timely detection of an unauthorized acquisition, use or disposition of the Company’s assets that could have a material effect on the financial statements.

pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the assets of the Company;
provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with GAAP, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company; and
provide reasonable assurance regarding prevention or timely detection of an unauthorized acquisition, use or disposition of the Company’s assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Our management assessed the effectiveness of our internal control over financial reporting as of December 31, 2017.2021. In making this assessment, our management used the criteria set forth in the 2013Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”).Commission. Based on its assessment, our management has determined that, as of December 31, 2017,2021, our internal controls over financial reporting are effective based on those criteria.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders of

Novavax, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Novavax, Inc. (the Company) as of December 31, 20172021 and 2016,2020, the related consolidated statements of operations, comprehensive loss, changes in stockholders’ equity (deficit), and cash flows for each of the three years in the period ended December 31, 2017,2021, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 20172021 and 2016,2020, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2017,2021, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2017,2021, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) and our report dated March 14, 2018February 28, 2022 expressed an unqualified opinion thereon.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current period audit of the financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective or complex judgments. The communication of the critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing a separate opinion on the critical audit matters or on the account or disclosures to which they relate.

/s/ Ernst & Young LLP
Revenue recognition related to the cost-based input method for U.S. government contracts
Description of the Matter
As described in Note 12 to the consolidated financial statements, the Company recorded approximately $811 million of revenue from U.S. government contracts to advance the clinical development and manufacturing of NVX-CoV2373 on a reimbursable-cost or reimbursable-cost-plus fixed fee basis. The Company measures progress toward satisfaction of its performance obligations using a cost-based input method that requires an estimate of total allowable cost at completion. Estimating the total allowable costs at completion is highly subjective. Changes in the estimated total allowable cost at completion could materially impact the timing of revenue recognition. Allowable contract costs include direct costs incurred on the contract and indirect costs that are applied in the form of rates to the direct costs.

Auditing revenue recognition based on the cost-based input method involved subjective auditor judgment. The estimates of costs at completion are based on management’s assessment of the costs necessary to fulfill its performance obligations under the contracts. Auditing allowable contract costs was complex due to the specialized knowledge needed to evaluate the costs included in the calculation of indirect rates and the contract terms.

F- 2

How We Addressed the Matter in Our AuditWe obtained an understanding, evaluated the design, and tested the operating effectiveness of controls over recognition of revenue under the cost-based input method. For example, we tested controls over the appropriateness of significant assumptions regarding the estimation of allowable costs to be incurred for the performance obligations and controls over the appropriateness of the indirect rate calculation.

To test the recognition of revenue under the cost-based input method, our audit procedures included among others, reviewing management’s estimate to total allowable costs at completion for consistency with contract terms, obtaining an understanding of the stage of completion through review of project deliverables, evidence of stage of completion including discussion with clinical research and manufacturing teams, and comparing actual results to prior management estimates. To test the recognition of revenue related to indirect rates, our audit procedures included among others, testing the allowability of the underlying costs used in the Company’s calculation of indirect rates. We utilized specialists to evaluate the treatment of significant indirect cost types.
Identification of embedded leases related to manufacturing supply agreements
Description of the Matter
As described in Note 7 to the consolidated financial statements, the Company entered into multiple supply agreements with contract manufacturing organizations and contract development and manufacturing organizations. The Company determined that certain of these arrangements contain embedded leases as it has the exclusive use of, and control over, a portion of the manufacturing facility or equipment of the contract manufacturing organization during the contractual term of the arrangements. As a result of identifying embedded leases in certain of these arrangements, the Company immediately expensed approximately $144 million, which represented the right of use assets related to these arrangements that did not have an alternative future use.

Auditing embedded leases within supply agreements was complex due to the judgment required to evaluate whether each arrangement included a lease and the related lease term. This significant auditor judgment involves the assessment of whether the Company has the right to obtain substantially all of the economic benefits from the use of identified assets and an assessment of the lease term, including whether the Company is reasonably certain not to exercise its termination provisions within the arrangements.

How We Addressed the Matter in Our Audit
We obtained an understanding, evaluated the design, and tested the operating effectiveness of controls over the identification of embedded leases in supply agreements. For example, we tested controls over management’s review of the supply agreements that evaluated whether management was entitled to substantially all of the economic benefits, as well as management’s assessment of the various termination provisions.

To test the Company’s identification of embedded leases, our audit procedures included among others, reviewing the terms of supply agreements with contract manufacturing organizations, obtaining an understanding of the facilities and equipment subject to the arrangements through discussions with representatives of the counterparties, and evaluating the identification of embedded leases and determination of the lease term.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders of

Novavax, Inc.

Opinion on Internal Control over Financial Reporting

We have audited Novavax, Inc.’s internal control over financial reporting as of December 31, 2017,2021, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, Novavax, Inc. (the Company) maintained, in all material respects, effective internal control over financial reporting as of December 31, 2017,2021, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 20172021 and 2016,2020, the related consolidated statements of operations, comprehensive loss, changes in stockholders’ equity (deficit), and cash flows for each of the three years in the period ended December 31, 2017,2021, and the related notes and our report dated March 14, 2018February 28, 2022 expressed an unqualified opinion thereon.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Report on Internal Control over Financial Reporting included in Item 9A. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.

Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

The Company’s vaccine candidates currently under development, some of which include adjuvants, will require significant additional researchNVX-CoV2373, to be manufactured and development efforts that include extensive preclinical studies and clinical testing, and regulatory approval prior to commercial use.

As a clinical-stage biotechnology company,marketed in the Company has primarily funded its operations with proceeds from the sale of its common stock in equity offerings, the issuance of convertible debt, revenue under its former contract with the Department of Health and Human Services, Biomedical Advanced Research and Development Authority (“HHS BARDA”) and more recently, revenuePhilippines by SIIPL under the grant agreement (“Grant Agreement”) with the Bill & Melinda Gates Foundation (“BMGF”)brand name CovovaxTM.Management regularly reviews the Company’s cash and cash equivalents and marketable securities relative to its operating budget and forecast to monitor the sufficiency of the Company’s working capital, and anticipates continuing to draw upon available sources of capital to support its product development activities. Based on the Company’s most recent cash flow forecast, the Company believes its current capital, along with anticipated revenue under the Grant Agreement (see Note 7), is sufficient to fund its operating plans for a minimum of twelve months from the date that this Annual Report was filed. The Company plans to meet its near term capital requirements primarily through cash and investments on hand, and a combination of equity and debt financings, collaborations, strategic alliances and marketing distribution or licensing arrangements and in the longer term, from revenue related to product sales, to the extent its product candidates receive marketing approval and can be commercialized. There can be no assurances that new financings will be available to the Company on commercially acceptable terms, if at all. Also, any collaborations, strategic alliances and marketing distribution or licensing arrangements may require the Company to give up some or all rights to a product or technology at less than its full potential value. If the Company is unable to perform under the Grant Agreement or obtain additional capital, the Company will assess its capital resources and may be required to delay, reduce the scope of, or eliminate one or more of its product research and development programs, and/or downsize its organization, including its general and administrative infrastructure.

Note 32 – Summary of Significant Accounting Policies

Basis of Presentation

The consolidated financial statements include the accounts of Novavax, Inc. and its wholly owned subsidiary,subsidiaries, including Novavax AB.AB and Novavax CZ. All intercompany accounts and transactions have been eliminated in consolidation.

Reclassifications
Certain amounts reported in prior periods have been reclassified to conform to current period financial statement presentation. These reclassifications have no material effect on previously reported financial position, cash flows, or results of operations.
The Company combined amounts previously reported as Government contracts revenue of $217.2 million and Grants revenue of $236.0 million for the year ended December 31, 2020, and Government contracts revenue of $7.5 million and Grants revenue of $8.4 million for the year ended December 31, 2019 into a single financial statement line item, Grants, in the consolidated statements of operations. Other revenue of $22.4 million for the year ended December 31, 2020, and $2.7 million for the year ended December 31, 2019 was reclassified to Royalties and other.
Use of Estimates

The preparation of the consolidated financial statements in conformity with generally accepted accounting principles generally accepted in the United States (“U.S. GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ materially from those estimates.

Marketable Securities

Marketable securities consist of debt securities with maturities greater than three months from the date of purchase that have historically included commercial paper, asset-backedgovernment-backed securities, treasury securities, corporate notes, and corporate notes.agency securities. Classification of marketable securities between current and non-current is dependent upon the maturity date at the balance sheet date taking into consideration the Company’s ability and intent to hold the investment to maturity.

Interest and dividend income isare recorded when earned and included in investment income in the consolidated statements of operations. Premiums and discounts, if any, on marketable securities are amortized or accreted to maturity and included in investment income in the consolidated statements of operations. The specific identification method is used in computing realized gains and losses on the sale of the Company’s securities.

The Company classifies its marketable securities with readily determinable fair values as “available-for-sale.” Investments in securities that are classified as available-for-sale are measured at fair market value in the consolidated balance sheets, and unrealized holding gains and losses on marketable securities are reported as a separate component of stockholders’ deficitequity (deficit) until realized. Marketable securities are evaluated periodically to determine whether a decline in value is “other-than-temporary.” The term “other-than-temporary” is not intended to indicate a permanent decline in value. Rather, it means that the prospects for a near term recovery of value are not necessarily favorable, or that there is a lack of evidence to support fair values equal to, or greater than, the carrying value of the security. Management reviews criteria, such as the magnitude and duration of the decline, as well as the Company’s ability to hold the securities, until marketincluding whether the Company will be required to sell a security prior to recovery of its amortized cost basis, the investment issuer’s financial condition and business outlook to predict whether the loss in value is other-than-temporary. If a decline in value is determined to be other-than-temporary, the value of the security is reduced and the impairment is recorded as other income (expense) in the consolidated statements of operations.

Fair Value Measurements
The Company applies Accounting Standards Codification (“ASC”) Topic 820, Fair Value Measurements and Disclosures (“ASC 820”), for financial and non-financial assets and liabilities.
ASC 820 discusses valuation techniques, such as the market approach (comparable market prices), the income approach (present value of future income or cash flow), and the cost approach (cost to replace the service capacity of an asset or replacement cost). The statement utilizes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. The following is a brief description of those three levels:
Level 1: Observable inputs such as quoted prices (unadjusted) in active markets for identical assets or liabilities.
Level 2: Inputs other than quoted prices that are observable for the asset or liability, either directly or indirectly. These include quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active.
Level 3: Unobservable inputs that reflect the reporting entity’s own assumptions.

Restricted Cash

The Company’s current and non-current restricted cash includes payments received under the Coalition for Epidemic Preparedness Innovations (“CEPI”) funding agreements, payments received under the Bill & Melinda Gates Foundation (“BMGF”) grant agreements, and cash collateral accounts under letters of credit that serve as security deposits for certain facility leases. CEPI and BMGF funds become unrestricted as the Company incurs expenses for services performed under these agreements. As of December 31, 2021 and 2020, the restricted cash balances (both current and non-current) consisted primarily of $10.4 million and $92.4 million, respectively, of payments under the CEPI funding agreements.

Accounts Receivable
The Company recognizes amounts due from customers as accounts receivable when its right to payment is unconditional. The Company has evaluated outstanding receivables to assess collectability, with consideration given to economic conditions, the aging of receivables, and customer-specific risks. There was no allowance for doubtful accounts as of December 31, 2021, and 2020. There was no bad debt expense for the years ended December 31, 2021, 2020 or 2019.
Concentration of Credit Risk

Financial instruments which possibly expose the Company to concentration of credit risk and consist primarily of cash and cash equivalents and marketable securities. The Company’s investment policy limits investments to certain types of instruments, including asset-backed securities, high-grade corporate debt securities, and money market funds, places restrictions on maturities and concentrations in certain industries and requires the Company to maintain a certain level of liquidity. At times, the Company maintains cash balances in financial institutions, which may exceed federally insured limits. The Company has not experienced any losses relating to such accounts and believes it is not exposed to a significant credit risk on its cash and cash equivalents.

Fair Value Measurements

The Company's accounts receivable arise from revenue arrangements with customers in different countries. The Company's revenue is primarily due to grants made by government-sponsored and private organizations, as well as royalties from our collaboration and license partners.

Restricted Cash

The Company’s current and non-current restricted cash includes payments received under the Grant Agreement (see Note 7) and cash collateral accounts under letters of credit that serve as security deposits for certain facility leases. The Company will utilize the fundsrealize future economic benefit from the Grant Agreementsales of the product candidate.

Upon the authorization of distribution and use of NVX-CoV2373 following regulatory authorizations by EMA and the WHO in December 2021, the Company began to capitalize inventory costs associated with the related supply of NVX-CoV2373, as it incurs expenses for services performed under the agreement. At December 31, 2017 and 2016, the restricted cash balances (both current and non-current) consist of payments received under the Grant Agreement of $27.4 million and $33.2 million, respectively, and security deposits of $1.7 million at both dates.

was determined that inventory costs subsequently incurred had a probable future economic benefit.

Property and Equipment

Property and equipment are stated at cost, net of accumulated depreciation. and are depreciated using the straight-line method over the estimated useful lives of the assets, generally three to seven years. Amortization of leasehold improvements is computed using the straight-line method over the shorter of the estimated useful lives of the improvements or the remaining term of the lease.assets. Repairs and maintenance costs are expensed as incurred.

The estimated useful lives of property and equipment are described below:

Lease Accounting

The Company enters into manufacturing supply agreements with contract manufacturing organizations (“CMO”) and contract development and manufacturing organizations (“CDMO”) to manufacture its vaccine candidates. Certain of these manufacturing supply agreements include the use of identified manufacturing facilities and equipment that are controlled by the Company and for which the Company obtains substantially all the output and may qualify as an embedded lease. The Company treats manufacturing supply agreements that contain a lease as lease arrangements in their entirety. The evaluation of leases that are embedded in the Company’s CMO and CDMO agreements is complex and requires judgment in determining whether the contract, either explicitly or implicitly, is for the use of an identified asset and the Company has the right to direct the use of, and obtain substantially all of the benefit from, the identified asset which generally, is the use of a portion of the manufacturing facility of the CMO or CDMO, whether the Company has the right to direct the use of, and obtain substantially all of the benefit from, the identified asset, the term of the lease, and the fixed lease payments under the contract. Depending on the contract, the lease commencement date, defined as the date on which the lessor makes the underlying asset available for use by the lessee and is the date on which the Company is required to accrue lease expenses, may be different than the inception date of the contract. The Company determines the non-cancellable lease term of its embedded leases based on the impact of certain expected milestones on its option to terminate the lease where it is reasonably certain to not exercise that option. The Company evaluates changes to the terms and conditions of a lease contract to determine if they result in a new lease or a modification of an existing lease. For lease modifications, the Company remeasures and reallocates the remaining consideration in the contract and reassesses the lease classification at the effective date of the modification. Leases are classified as either operating or finance leases based on the economic substance of the agreement. The Company also enters into non-cancelable lease agreements for facilities and certain equipment.

For leases that have a lease term of more than 12 months at the lease commencement date, the Company recognizes lease liabilities, which represent the Company’s obligation to make lease payments arising from the lease, and corresponding right-of-use (“ROU”) assets, which represent the right to use an underlying asset for the lease term, based on the present value of the fixed future payments over the lease term. The Company calculates the present value of future payments using the discount rate implicit in the lease, if available, or the Company’s incremental borrowing rate. For all leases that have a lease term of 12 months or less at the commencement date (referred to as “short-term” leases), the Company has elected to apply the practical expedient in ASC Topic 842, Leases (“ASC 842”), to not recognize a lease liability or ROU asset but, instead, recognize lease payments as an expense on a straight-line basis over the lease term and variable lease payments that do not depend on an index or rate as an expense in the period in which the variable lease costs are incurred based on performance or usage in accordance with contractual agreements. In determining the lease period, the Company evaluates facts and circumstances that could affect the period over which it is reasonably certain to use the underlying asset while taking into consideration the non-cancelable period over which it has the right to use the underlying asset and any option period to extend or terminate the lease if it is reasonably certain to exercise the option. The Company re-evaluates short-term leases that are modified and if they no longer meet the requirements to be treated as a short-term lease, recognizes and measures the lease
F- 12

liability and ROU asset as if the date of the modification is the lease commencement date. For short-term leases that are modified and continue to meet the requirements to be treated as a short-term lease, the Company remeasures the fixed lease payments under the modified lease and recognize lease payments as an expense on a straight-line basis over the modified lease term.

For operating leases, the Company recognizes lease expense related to fixed payments on a straight-line basis over the lease term and lease expense related to variable payments as incurred based on performance or usage in accordance with the contractual agreements. For finance leases, the Company recognizes the amortization of the ROU asset over the shorter of the lease term or useful life of the underlying asset. The Company expenses ROU assets acquired for research and development activities under ASC Topic 730, Research and Development, if they do not have an alternative future use, in research and development projects or otherwise.

The Company uses significant assumptions and judgment in evaluating its lease contracts and other agreements under ASC 842, including the determination of whether an agreement is or contains a lease, whether a change in the terms and conditions of a lease contract represent a new or modified lease, whether a lease represents an operating or finance lease, the discount rate used to determine the present value of lease obligations, and the term of a lease embedded in its manufacturing supply agreements.

Intangible Assets
The Company’s intangible assets include proprietary adjuvant technology and collaboration agreements, which were measured at the estimated fair values as of their acquisition dates. Amortization expense for intangible assets is recorded on a straight-line basis over the expected useful lives of the assets, ranging from 7 years to 20 years.
Impairment of Long-Lived Assets

Long-lived assets, including property and equipment and finite-lived intangible and right-of-use assets, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or asset group may not be recoverable based on the criteria for accounting for the impairment or disposal of long-lived assets under ASC Topic 360,Property, Plant and Equipment.

The Company calculates the estimated fair value of a long-lived asset (group) using the income approach. Impairment losses are recognized when the sum of expected future cash flows is less than the assets’ (group’s) carrying value.

Goodwill

Goodwill is subject to impairment tests annually or more frequently should indicators of impairment arise. The Company has determined that, because its only business is the development of recombinant vaccines, it operates as a single operating segment and has one1 reporting unit. The Company primarily utilizes primarily the market approach and, if considered necessary, the income approach to determine if it has an impairment of its goodwill. The market approach is based on market value of invested capital. To ensure that the Company’s capital stock is the appropriate measurement of fair value, the Company considers factors such as its trading volume, diversity of investors, and analyst coverage. If considered necessary, the income approach is used to corroborate the results of the market approach. Goodwill impairment may exist if the carrying value of the reporting unit exceeds its estimated fair value. If the carrying value of the reporting unit exceeds its fair value, step two of the impairment analysis is performed. In step two of the analysis, an impairment loss is recorded equal to the excess of the carrying value of the reporting unit’s goodwill over its implied fair value, should such a circumstance arise.

At December 31, 2017October 1, 2021 and 2016,2020, the Company used the market approach to determine if the Company had an impairment of its goodwill. The fair value of the Company’s single reporting unit was substantially higher than its carrying value, resulting in no impairment to goodwill at December 31, 2017 and 2016.

Other Intangible Assets

The Company’s intangible assets include proprietary adjuvant technology and collaboration agreements, which were measured at their estimated fair values as of their acquisition dates. Amortization expense for intangible assets is recorded on a straight-line basis overOctober 1, 2021 and 2020.

Revenue Recognition
At contract inception, the expected useful livesCompany analyzes its revenue arrangements to determine the appropriate accounting under U.S. GAAP. Currently, the Company’s revenue arrangements represent customer contracts within the scope of the assets, rangingASC Topic 606, Revenue from seven to 20 years. Intangible assetsContracts with Customers (Topic 606) (“ASC 606”), or are subject to amortization are reviewed for impairment whenever events or changesthe contribution guidance in circumstances indicateASC Topic 958-605, Not-for-Profit Entities – Revenue Recognition (“ASC 958-605”), which applies to business entities that receive contributions within the carrying amountscope of an intangible asset may not be recoverable. The Company’s evaluation of intangible assets completed during the years ended December 31, 2017 and 2016 resulted in no impairment losses.

Grants

Grant revenue includes both revenue from government contracts and the Company’s proportionate share of earnings or losses and distributions up to the amount initially invested or advanced.

Revenue Recognition

grants from organizations such as CEPI. The Company performs research and development for U.S. Government agencies and on behalf of grantors and other collaborators under cost reimbursable and fixed price contracts, includinggovernment funding, grant, license, grant and clinical development agreements. The revenue primarily consists of funding under U.S. government contracts and other arrangements to advance the clinical development and manufacturing of NVX-CoV2373. The Company’s U.S. government contracts are with the U.S. Department of Defense (the “DoD”) and the U.S. government partnership formerly known as Operation Warp Speed (“OWS”) (see Note 12). Other funding arrangements primarily include a grant and forgivable loan funding from CEPI (see Note 12).


Under the U.S. government contracts, the Company is entitled to receive funding on a cost-reimbursable or cost-reimbursable-plus-fixed-fee basis, to support certain activities related to the development, manufacture, and delivery of NVX-CoV2373 to the U.S. government. The Company analyzed these contracts and determined that they are within the scope of ASC 606. The obligations under each of the contracts are not distinct in the context of the contract as they are highly interdependent or interrelated and, as such, they are accounted for as a single performance obligation. The transaction price under these arrangements is the consideration the Company is expecting to receive and consists of the funded contract amount and the unfunded variable amount to the extent that it is probable that a significant reversal of revenue will not occur. The Company recognizes revenue under researchfor these contracts whenover time as the Company transfers control over the goods and services and satisfies the performance obligation. The Company measures progress toward satisfaction of the performance obligation using an Estimate-at-Completion (“EAC”) process, which is a cost-based input method that reviews and monitors the progress towards the completion of the Company’s performance obligation. Under this process, management considers the costs that have been incurred to-date, as well as projections to completion using various inputs and assumptions, including, but not limited to, progress towards completion, labor costs and level of effort, material and subcontractor costs, indirect administrative costs, and other identified risks. Estimating the total allowable cost at completion of the performance obligation under a contract has been executed,is subjective and requires the Company to make assumptions about future activity and cost drivers. Changes in these estimates can occur for a variety of reasons and, if significant, may impact the timing of revenue and fee recognition on the Company’s contracts. Allowable contract costs include direct costs incurred on the contract price is fixed or determinable, deliveryand indirect costs that are applied in the form of services or products has occurredrates to the direct costs. Progress billings under the contracts are initially based on provisional indirect billing rates, agreed upon between the Company and collectionthe U.S. government. These indirect rates are subject to review on an annual basis. The Company records the impact of changes in the indirect billing rates in the period when such changes are identified. These changes reflect the difference between actual indirect costs incurred compared to the estimated amounts used to determine the provisional indirect billing rates agreed upon with the U.S. government. The Company recognizes revenue on the U.S government contracts based on reimbursable allowable contract costs incurred in the period up to the transaction price. For cost-reimbursable-plus-fixed-fee contracts, the Company recognizes the fixed-fee based on the proportion of reimbursable contract costs incurred to total estimated allowable contract costs expected to be incurred on completion of the contractunderlying performance obligation as determined under the EAC process. The Company recognizes changes in estimates related to the EAC process in the period when such changes are made on a cumulative catch-up basis. The Company includes the transaction price comprising both funded and unfunded portions of customer contracts in this estimate.

The Company’s other funding agreements currently include funding from CEPI in the form of a grant (“CEPI Grant Funding”) and one or more forgivable no interest term loans (“CEPI Forgivable Loan Funding”). Under the Company’s grant funding arrangements, currently including the CEPI and BMGF arrangements, the Company is reasonably assured.primarily entitled to reimbursement for costs that support development related activities of NVX-CoV2373. The Company analyzed these other funding arrangements and determined that they are not within the scope of ASC 606 as they do not provide a direct economic benefit to the grantor. Payments received in advanceunder the grant funding arrangements are considered conditional contributions under the scope of work performedASC 958-605 and are recorded as deferred revenue and losses on contracts, if any, are recognized in the period in which they become known.

Under its Grant Agreement with BMGF (see Note 7), the Company is reimbursed for certain costs that support development activities, including the Company’s global Phase 3 clinical trial in pregnant women in their third trimester, product licensing efforts and efforts to obtain World Health Organization (“WHO”) prequalification of its RSV F Vaccine. Payments received under the Grant Agreement are recognized as revenue inuntil the period in which such research and development activities are performed.actually performed in a manner that satisfies the funder-imposed conditions. Payments received under the CEPI Forgivable Loan Funding agreement are only repayable if the proceeds of sales to one or more third parties of NVX-CoV2373 cover the Company’s costs of manufacturing such vaccine candidate, not including manufacturing costs funded by CEPI. As the financial risk remains with CEPI, the Company determined that the use of the funds from the CEPI agreement is outside the scope of ASC Topic 470, Debt. The research and development risk was considered substantive, such that it was not probable that the development would be successful at the inception of the contract. Therefore, the Company concluded that ASC 730 was considered applicable and most appropriate. Given the financial risk associated with the research and development activities lies with CEPI because repayment of any funds provided by CEPI depends solely on the results of the research and development activities having future economic benefit, the Company has accounted for the obligation under the CEPI Forgivable Loan Funding as a contract to perform research and development for others. The Company analyzes its grant agreements to determine whether thehas determined that payments received under these agreements should be recorded as revenue or asunder ASC 958-605 rather than a reduction to research and development

expenses. This is consistent with the Company’s policy of presenting such amounts as revenue. In reaching this determination, management considersthe Company considered a number of factors, including whether the Companyit is principal under the arrangement, and whether the arrangement is significant to, and part of, the Company’s core operations. Historically, payments received under grant agreements have been recognized as revenue since theThe Company acts as a principal in the arrangement and the activities are core to its operations.

Under cost reimbursable contracts with U.S. Government agencies, the Company is reimbursed and recognizeswill record revenue as allowable costs are incurred plus a portion ofit performs the fixed-fee earned. The Company considers fixed-fees under cost reimbursable contracts to be earned in proportion to the allowable costs incurred in performance of the work as compared to total estimated contract costs, with such costs incurred representing a reasonable measurement of the proportional performance of the work completed. Under its HHS BARDA contract (see Note 7), certain activities were pre-approved by HHS BARDA in order for their costs to be deemed allowable direct costs. Direct costs incurred under cost reimbursable contracts are recorded ascontractual research and development expenses. Paymentsservices.

Royalties and Other
The Company also has various arrangements that include a right for a third party to use the Company's intellectual property as a functional license. These licensing arrangements include sales-based royalties, certain development and commercial milestone payments, and the sale of proprietary Matrix-MTM adjuvant. The license is deemed to be the predominant item to which the sales-based royalties or milestone payments relate. Because development milestone payments are contingent on the achievement of milestones, such as regulatory approvals, that are not within the Company under cost reimbursable contracts with agenciesor licensee's control, the payments are not considered probable of being achieved and are excluded from the transaction price until the milestone is achieved. The Company recognizes revenue when the development milestone is achieved. For arrangements that include sales-based royalties, including milestone payments based upon the achievement of a certain level of product sales, wherein the license is deemed to be the sole or predominant item, the Company recognizes revenue on the satisfaction (or partial satisfaction) of the U.S. Government, such asperformance obligation, which is when the HHS BARDArelated sales occur.
The Company allocates the transaction price to each performance obligation based on a relative standalone selling price basis. It develops assumptions that require judgment to determine the standalone selling price for each performance obligation in consideration of applicable market conditions and relevant entity-specific factors, including factors that were contemplated in negotiating the agreement with the customer.
Research and Development Expenses
Research and development expenses include salaries, stock-based compensation, laboratory supplies, consultants and subcontractors, including external contract are provisional payments subject to adjustment upon audit by the government. When the final determination of the additional reimbursable costs for any year has been made,research organizations (“CROs”), CMOs, and such amount is knownCDMOs and collection of the amount is reasonably assured, revenue and billings will be adjusted accordingly.

Revenue associated with upfront payments under arrangements is recognized over the contract term or when all obligationsother expenses associated with the upfront payment have been satisfied.

Company’s process development, manufacturing, clinical, regulatory, and quality assurance activities for its clinical development programs. In addition, related indirect costs such as fringe benefits and overhead expenses are also included in research and development expenses.

The Company estimates its research and development expense related to services performed under its contracts with external service providers based on an estimate of the level of service performed in the period. Research and development activities are expensed as incurred.
Accrued Research and Development Expenses
The Company accrues research and development expenses, including clinical trial-related expenses, as the services are performed, which may include estimates of those expenses incurred, but not invoiced. The Company uses information provided by third-party service providers and CROs, CMOs, and CDMOs invoices and internal estimates to determine the progress of work performed on the Company’s behalf. Assumptions based on clinical trial protocols, contracts, and participant enrollment data are also developed to determine and analyze these estimates and accruals.

The Company accounts for stock-based compensation related to grants of stock options, stock appreciation rights, restricted stock awards, and purchases under itsthe Company’s Employee Stock Purchase Plan, as amended and restated (the “ESPP”), at fair value. The Company recognizes compensation expense related to such awards on a straight-line basis over the requisite service period (generally the vesting period) of the equity awards, whichbased on the award's fair value at the grant date. The requisite service period is typically occurs ratably over periods ranging from six monthsone to four years. Effective January 1, 2017, the Company accountsForfeitures for forfeitures when they occur. See Note 11 for a further discussion on stock-based compensation.

all awards are recognized as incurred.

The expected term of stock options and stock appreciation rights granted wasis based on the Company’s historical option exercise experience and post-vesting forfeiture experience using the historical expected term from the vesting date, whereas the expected term for purchases under the ESPP wasis based on the purchase periods included in the offering. The expected volatility wasis determined using historical volatilities based on stock prices over a look-back period corresponding to the expected term. The risk-free interest rate wasis determined using the yield available for zero-coupon U.S. Governmentgovernment issues with a remaining term equal to the expected term. The Company has never paid a dividend, and as such, the dividend yield is zero, and the Company does not intend to pay dividends in the foreseeable future.

Table of amortization.

The Company accounts for share-based awards issued to non-employees by determining the fair value of equity awards given as consideration for services rendered to be recognized as compensation expense over the shorter of the vesting or service periods. In cases where an equity award is not fully vested, such equity award is revalued on each subsequent reporting date until vesting is complete with a cumulative catch-up adjustment recognized for any changes in its estimated fair value.

Research and Development Expenses

Research and development expenses include salaries, stock-based compensation, laboratory supplies, consultants and subcontractors, including external contract research organizations (“CROs”), and other expenses associated with the Company’s process development, manufacturing, clinical, regulatory and quality assurance activities for its programs. In addition, related indirect costs such as, fringe benefits and overhead expenses, are also included in research and development expenses. Research and development activities are expensed as incurred.

Accrued Research and Development Expenses

The Company accrues research and development expenses, including clinical trial-related expenses, as the services are performed, which may include estimates of those expenses incurred, but not invoiced. The Company uses information provided by third-party service providers and CROs, invoices and internal estimates to determine the progress of work performed on the Company’s behalf. Assumptions based on clinical trial protocols, contracts and participant enrollment data are also developed to determine and analyze these estimates and accruals.

Income Taxes

The Company accounts for income taxes in accordance with ASC Topic 740,Income Taxes. Under the liability method, deferred income taxes are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis and operating loss carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the year in which those temporary differences are expected to be recovered or settled. The effect of changes in tax rates on deferred tax assets and liabilities is recognized in income in the period such changes are enacted. A valuation allowance is established when necessary to reduce net deferred tax assets to the amount expected to be realized.

Tax benefits associated with uncertain tax positions are recognized in the period in which one of the following conditions is satisfied: (1) the more likely than not recognition threshold is satisfied; (2) the position is ultimately settled through negotiation or litigation; or (3) the statute of limitations for the taxing authority to examine and challenge the position has expired. Tax benefits associated with an uncertain tax position are reversed in the period in which the more likely than not recognition threshold is no longer satisfied.

Interest

The Company has historically generated significant federal, state, and penaltiesforeign tax net operating losses, which may be subject to limitation in future periods. Management has fully reserved the related to incomedeferred tax matters are recordedassets with a valuation allowance in the current reporting period as income tax expense. At December 31, 2017 and 2016,it is more likely than not that the Company had no accruals for interest or penalties related to income tax matters.

On December 22, 2017, the Tax Cuts and Jobs Act of 2017 (the “Act”) was enacted into law, and the new legislation contains certain key tax provisions that affected the Company, including a reduction of the corporate income tax rate from 35% to 21% effective for tax years beginning after December 31, 2017, among others.benefit will not be realized. The Company is requiredcurrently subject to recognizeexamination in all open tax years.

During the effect of the tax law changes in the period of enactment, such as re-measuring its U.S. deferred tax assets and liabilities as well as reassessing the net realizable amounts of its deferred tax assets and liabilities. Inyear ended December 2017, the SEC issued Staff Accounting Bulletin No. 118,Income Tax Accounting Implications of the Tax Cuts and Jobs Act (“SAB 118”), which allows31, 2021, the Company to record provisional amounts during a measurement period not to extend beyond one year of the enactment date. Since the Act was passed laterecognized $29.2 million in the fourth quarter of 2017, and ongoing guidance and accounting interpretation are expected over the next 12 months, the Company considers the deferred tax re-measurements and other items to be incomplete due to the forthcoming guidance and its ongoing analysis of final year-end data and tax positions. The Company expects to complete its analysis within the measurement period in accordance with SAB 118, although it does not expect there to be any adjustment to the income tax expense related to foreign withholding tax on royalties.

Net loss per share is computed usingby dividing net loss by the weighted averageweighted-average number of shares of common stock outstanding.outstanding for the period. Diluted net loss per share is computed by dividing net loss by the weighted-average number of common shares outstanding after giving consideration to the dilutive effect of certain securities outstanding during the period. At December 31, 2017, 20162021, 2020, and 2015,2019, the Company had potentially dilutive outstanding stock options, stock appreciation rights, and unvested restricted stock awards totaling 46,513,399, 39,277,732units. The Company has generated a net loss in all periods presented; therefore the basic and 23,832,545 shares, respectively.diluted net loss per share are the same because the inclusion of the potentially dilutive securities would be anti-dilutive.

Recent Accounting Pronouncements

Recently

Not Yet Adopted


In March 2016,August 2020, the Financial Accounting Standards Board (“FASB”("FASB") issued Accounting Standards Update (“ASU”("ASU") 2016-09, Compensation - Stock Compensation (Topic 718) that simplifiesNo. 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity (“ASU 2020-06”), which will simplify the accounting for share-based payment transactions, including the income tax consequences, the treatmentcertain financial instruments with characteristics of forfeitures, classification of awards as either equity or liabilities and classificationequity, including certain convertible instruments and contracts on the statement of cash flows. The Company adopted this standard on the effective date, January 1, 2017, and, as part of the adoption, elected to account for forfeitures when they occur. The impact from adoption of the provisions related to forfeitures was reflected in the Company’s consolidated financial statements on a modified retrospective basis, resulting in an adjustment to accumulated deficit of $0.6 million.

Not Yet Adopted

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606) (“ASU 2014-09”), which supersedes nearly all existing revenue recognition guidance under Topic 605, Revenue Recognition. The new standard requires a company to recognize revenue when it transfers goods and services to customers in an amount that reflects the consideration that the company expects to receive for those goods or services. ASU 2014-09 defines a five-step process that includes identifying the contract with the customer, identifying the performance obligations in the contract, determining the transaction price, allocating the transaction price to the performance obligations in the contract and recognizing revenue when (or as) the entity satisfies the performance obligations. In July 2015, the FASB approved a one-year deferral of the effective date ofentity’s own equity. Specifically, the new standard will remove the separation models required for convertible debt with cash conversion features and convertible instruments with beneficial conversion features. It will also remove certain settlement conditions that are currently required for equity contracts to 2018qualify for public companies, with an option that would permit companies to adopt the new standard as early asderivative scope exception and will simplify the original effective date of 2017. Early adoption prior to the original effective date is not permitted.diluted earnings per share calculation for convertible instruments. ASU 2014-09 allows for either full retrospective or modified retrospective adoption. The Company has completed an assessment of the potential changes from adopting ASU 2014-09, primarily by reviewing its current revenue streams and deferred revenue balances, and determined there will be no material change to the recognition of its revenue. The Company will apply ASU 2014-09 on a modified retrospective basis as of January 1, 2018.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) that increases transparency and comparability among organizations by requiring the recognition of lease assets and lease liabilities on the balance sheet and disclosure of key information about leasing arrangements for both lessees and lessors. The standard2020-06 will be effective January 1, 2019 for the Company, with early adoption permitted. The standard will be applied using a modified retrospective approach to the beginning of the earliest period presented in the financial statements.  The Company is expecting to adopt this standard on January 1, 2019 and is currently evaluating the potential impact to its consolidated financial statements and related disclosures.

F-13

In November 2016, the FASB issued ASU 2016-18,Statement of Cash Flows - Restricted Cash (“ASU 2016-18”), which requires that the change in total cash and cash equivalents at the beginning of period and end of period on the statement of cash flows include restricted cash and restricted cash equivalents. ASU 2016-18 also requires companies who report cash and cash equivalents and restricted cash separately on the balance sheet to reconcile those amounts to the statement of cash flows. The standard will be effective January 1, 20182022 for the Company and will be applied using a modified retrospective transition method to each period presented. The Companyapproach. Management has evaluated the impact of adopting ASU 2020-06 and has determined that it will adopt ASU 2016-18 as of January 1, 2018. Although the Company’s restricted cash will be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows, the adoption is not expected to have a material impact on the other aspectsCompany’s consolidated financial statements.

Note 3 – Marketable Securities
The Company had no marketable securities classified as available-for-sale as of December 31, 2021 as all of the Company’s consolidatedCompany's investments were in securities classified as cash flow statements, or its consolidated financial statementsand cash equivalents. Marketable securities classified as a whole, including related disclosures.

In January 2017, the FASB issued ASU No. 2017-04, Intangibles-Goodwill and Other (Topic 350) (“ASU 2017-04”), which will simplify the goodwill impairment calculation by eliminating Step 2 from the current goodwill impairment test. The new standard does not change how a goodwill impairment is identified. The Company will continue to perform its quantitative goodwill impairment test by comparing the fair valueavailable-for-sale as of its reporting unit to its carrying amount, but if the Company is required to recognize a goodwill impairment charge, under the new standard, the amountDecember 31, 2020 were comprised of the charge will be calculated by subtracting the reporting unit’s fair value from its carrying amount. Under the current standard, if the Company is required to recognize a goodwill impairment charge, Step 2 requires it to calculate the implied value of goodwill by assigning the fair value of a reporting unit to all of its assets and liabilities as if that reporting unit had been acquired in a business combination and the amount of the charge is calculated by subtracting the reporting unit’s implied fair value of goodwill from the goodwill carrying amount. The standard will be effective January 1, 2020 for the Company, with early adoption permitted, and should be applied prospectively from the date of adoption. The Company is currently evaluating when it will adopt ASU 2017-04 and its expected impact to related disclosures.

Over time, the Company expects a market for the Notes to develop. At that time, the Company intends to use trade data as the principal basis for measuring fair value.

During the years ended December 31, 2017 and 2016, the Company did not have any transfers between Levels.

The amount in the Company’s consolidated balance sheets for accounts payable approximates its fair value due to its short-term nature. The Company’s milestone payment due to Wyeth (see Note 14) also approximates its fair value at December 31, 2017.

Allocation of Purchase Price to Assets Acquired and Liabilities Assumed

The Company has accounted for the Acquisition as a business combination using the acquisition method of accounting, with the Company as the acquirer. The acquisition method requires the Company to record the assets acquired and liabilities assumed at fair value. The amount by which the purchase price exceeds the fair value of net assets acquired is recorded as goodwill. The Company completed the appraisal process necessary to assess the fair values of the assets acquired and liabilities assumed to determine the amount of goodwill to be recognized as of the Acquisition Date. The final determination of the fair value of all assets and liabilities was completed in 2020 and is presented in the table below.

The table below summarizes the final allocation of the purchase price based upon the fair values of assets acquired and liabilities assumed (in thousands):

May 27, 2020
Prepaid expense and other current assets$326 
Property and equipment96,739 
Goodwill70,662 
Accounts payable(1,193)
Accrued expenses(205)
Other non-current liabilities(813)
Purchase price, net of cash acquired$165,516 

The fair value of the assets acquired and liabilities assumed was determined using market and cost valuation methodologies. The fair value measurements were based on significant unobservable inputs that were developed by the Company using publicly available information, market participant assumptions, and cost and development assumptions. Because of the use of significant unobservable inputs, the fair value measurements represent a Level 3 measurement as defined in ASC 820. The market approach is a valuation technique that uses prices and other relevant information generated by market transactions involving identical or comparable assets, liabilities, or a group of assets or liabilities. The cost approach estimates value by determining the current cost of replacing an asset with another of equivalent utility. The cost to replace a given asset reflects the estimated reproduction or replacement cost for the property, less an allowance for loss in value due to depreciation.

The cost approach was the primary approach used to value fixed assets, including the real property. Fixed assets are depreciated on a straight-line basis over their expected remaining useful lives, ranging from four years to 25 years.

The Company recorded $70.7 million in goodwill related to the Acquisition representing the purchase price that was in excess of the fair value of the assets acquired and liabilities assumed. The goodwill generated from the Acquisition is not expected to be deductible for U.S. federal income tax purposes. The goodwill recognized is attributable to intangible assets that do not qualify for separate recognition, such as the assembled workforce of Novavax CZ.

Current assets and current liabilities were recorded at their contractual or historical acquisition amounts, which approximate their fair value.

Impact to Financial Results for the Year Ended December 31, 2020

The results of operations from Novavax CZ have been included in the consolidated financial statements since the Acquisition Date. As a result, the consolidated financial results for the year ended December 31, 2020 does not reflect a full twelve months of Novavax CZ results. From the Acquisition Date through December 31, 2020, Novavax CZ did not recognize any revenue and recorded a net loss from operations of $11.3 million.

The Company incurred approximately $2.7 million of costs related to the Acquisition in the year ended December 31, 2020, which are included within general and administrative expenses in the consolidated statements of operations.

Supplemental Pro Forma Financial Information (Unaudited)

The unaudited pro forma financial information below gives effect to the Acquisition as if it had occurred as of January 1, 2019. The pro forma financial information is presented for informational purposes only and is not necessarily indicative of the results of operations that would have been achieved had the Acquisition been consummated as of that time. The unaudited pro forma financial information combines the historical results of operations of the Company and Novavax CZ and reflects the application of certain pro forma adjustments (in thousands, except per share amounts):

Note 7 – Leases

The Company has embedded leases related to multiple manufacturing supply agreements with CMOs and CDMOs to manufacture the Company’s COVID-19 vaccine candidate, NVX-CoV2373, as well as operating leases for its research and development and manufacturing facilities, corporate headquarters and offices, and certain equipment.

During 2021 and 2020, the Company entered into various CMO and CDMO manufacturing supply agreements that include the use of identified manufacturing facilities and contain fixed or minimum commitments. The Company evaluated the agreements at inception and determined that certain of these arrangements contain an embedded lease under ASC 842 as it has the exclusive use of, and control over, a portion of the manufacturing facility and equipment of the supplier during the contractual term of the arrangement. The Company classified the CMO and CDMO arrangements as operating and finance leases based on the terms of the GACA, among other things,agreement. The Company recognized lease expense related to fixed payments for its short-term operating leases on a straight-line basis over the lease term and lease expense related to variable payments as incurred based on performance or usage in accordance with the contractual agreements.

For leases that were previously determined to represent short-term embedded leases, the modifications did not result in a change in lease classification.

During 2021 and accessible2020, the Company recognized ROU assets of $144.4 million and $245.9 million, respectively, for its finance leases and long-term operating related to leases embedded in CMO and CDMO manufacturing supply agreements. The Company expensed the ROU assets since they relate to research and development activities for the development of NVX-CoV2373 for which the Company does not have an alternative future use.

During 2021, the Company entered into and extended various facility lease agreements related to research and development facilities and office space. During 2020, the Company entered into a lease agreement for the premises located at affordable pricing700 Quince Orchard Road, Gaithersburg, Maryland ("700QO").

HHS BARDA Contract for Recombinant Influenza Vaccines

HHS BARDA awarded the Company a contract in 2011, which funded the development of both the Company’s quadrivalent seasonal and pandemic influenza virus-like particle (“VLP”) vaccine candidates. The contract with HHS BARDA was a cost-plus-fixed-fee contract, which reimbursed the Company for allowable direct contract costs incurred plus allowable indirect costs and a fixed-fee earned in the ongoing clinical development and product scale-up of its multivalent seasonal and monovalent pandemic H7N9 influenza VLP vaccine candidates. In September 2014, HHS BARDA exercised and initiated a two-year option to the contract, which included scope to support development activities leading up to planned Phase 3 clinical studies, added $70 million of funding on top of the remainder of the $97 million base period funding and extended the contract until September 2016. In June 2015, the contract was amended to increase the funding by $7.7 million to allowdiscount rate):

Note 8 – Long-Term Debt
Convertible Notes
In 2016, the Company issued $325 million aggregate principal amount of convertible senior unsecured notes that will mature on February 1, 2023 (the “Notes”). The Notes are senior unsecured debt obligations and were issued at par. The Notes were issued pursuant to an indenture dated January 29, 2016 (the “Indenture”) between the Company and the trustee. The Company received $315.0 million in net proceeds from the offering after deducting underwriting fees and offering expenses. The Notes bear cash interest at a rate of 3.75%, payable on February 1 and August 1 of each year, beginning on August 1, 2016. The Notes are not redeemable prior to maturity and are convertible into shares of the Company’s common stock. As a result of the Company’s one-for-twenty reverse stock split in 2019 and pursuant to Section 14.04(a) of the Indenture, the Notes are initially convertible into approximately 2,385,800 shares of the Company’s common stock based on the initial conversion rate of 7.3411 shares of the Company’s common stock per $1,000 principal amount of the Notes. This additional amount was receivedrepresents an initial conversion price of approximately $136.20 per share of the Company’s common stock, representing an approximate 22.5% conversion premium based on the last reported sale price of the Company’s common stock of $111.20 per share on January 25, 2016. In addition, the holders of the Notes may require the Company to repurchase the Notes at par value plus accrued and recorded as revenueunpaid interest following the occurrence of a Fundamental Change (as described in the second quarterIndenture). If a holder of 2015.the Notes converts upon a Make-Whole Adjustment Event (as described in the Indenture), they may be eligible to receive a make-whole premium through an increase to the conversion rate up to a maximum of 8.9928 shares per $1,000 principal amount of Notes (subject to other adjustments as described in the Indenture).
The HHS BARDA contract expiredNotes are accounted for in accordance with ASC 470-20, Debt with Conversion and Other Options (“ASC 470-20”) and ASC 815-40, Contracts in Entity’s Own Equity (“ASC 815-40”). Under ASC 815-40, to qualify for equity classification (or non-bifurcation, if embedded) the instrument (or embedded feature) must be both (1) indexed to the issuer’s stock and (2) meet the requirements of the equity classification guidance. Based upon the Company’s analysis, it was determined the Notes do contain embedded features indexed to its terms in September 2016.  Billingsown stock, but do not meet the requirements for bifurcation, and therefore do not need to be separately accounted for as an equity component. Since the embedded conversion feature meets the equity scope exception from derivative accounting, and also since the embedded conversion option does not need to be separately accounted for as an equity component under ASC 470-20, the contractproceeds received from the issuance of the convertible debt were provisional billings, subjectrecorded as a liability on the consolidated balance sheets.
F- 22

In connection with the issuance of the Notes, the Company also paid $38.5 million, including expenses, to adjustmententer into privately negotiated capped call transactions with certain financial institutions (the “capped call transactions”). The capped call transactions are generally expected to reduce the potential dilution upon audit byconversion of the government, and were based on approved provisional indirect billing rates, which permit recovery of fringe benefits, overhead and general and administrative expenses. These indirect rates are subject to audit by HHS BARDA on an annual basis. An audit of indirect rates for the years ended December 31, 2013 and 2014 was completedNotes in the first quarter of 2017. Whenevent that the final determination of the additional reimbursable costs for the years ended December 31, 2013 and 2014 has been made, and such amount is known and collection of the amount is reasonably assured, revenue and billings will be adjusted accordingly. The Company has recognized approximately $114 million in revenue under the HHS BARDA contract since the inception of the contract.

CPLB Joint Venture

In 2009, the Company formed a joint venture with Cadila Pharmaceuticals Limited (“Cadila”), CPLB, to develop and manufacture vaccines, biological therapeutics and diagnostics in India. CPLB is owned 20% by the Company and 80% by Cadila. Because CPLB’s activities and operations are controlled and funded by Cadila, the Company accounts for its investment using the equity method. Since the carrying valuemarket price per share of the Company’s initial investment was nominal,common stock, as measured under the terms of the capped call transactions, is greater than the strike price of the capped call transactions, which initially corresponds to the conversion price of the Notes, and is subject to anti-dilution adjustments generally similar to those applicable to the conversion rate of the Notes. The cap price of the capped call transactions will initially be $194.60 per share, which represented a premium of approximately 75% based on the last reported sale price of the Company’s common stock of $111.20 per share on January 25, 2016, and is subject to certain adjustments under the terms of the capped call transactions. If, however, the market price per share of the Company’s common stock, as measured under the terms of the capped call transactions, exceeds the cap price, there would nevertheless be dilution upon conversion of the Notes to the extent that such market price exceeds the cap price. The Company evaluated the capped call transactions under ASC 815-10, Derivatives and Hedging – Overall and determined that it should be accounted for as a separate transaction and that the capped call transactions will be classified as an equity instrument.

The Company incurred approximately $10.0 million of debt issuance costs in 2016 relating to the issuance of the Notes, which were recorded as a reduction to the Notes on the consolidated balance sheet. The $10.0 million of debt issuance costs is being amortized and recognized as additional interest expense over the seven-year contractual term of the Notes on a straight-line basis, which approximates the effective interest rate method. The Company also incurred $0.9 million of expenses related to the capped call transactions, which were recorded as a reduction to additional paid-in-capital.

The Company used the Monte Carlo simulation model to determine the fair value of its 1.7 million shares of stock options containing a market conditionperformance obligations that were granted in 2016 (the “Performance Options”). The fair value of the Performance Optionsunsatisfied (or partially unsatisfied), excluding amounts related to sales-based royalties, was estimated with the following assumptions: 99.11% volatility, a 1.74% risk-free interest rate, 5.62% forfeiture rate and 0% dividend yield, which resulted in fair values of $0.74 to $0.92, and expected terms of 1.35 years to 3.50 years.

The total aggregate intrinsic value and weighted-average remaining contractual term of stock options outstanding under the 2015 Plan and 2005 Planapproximately $8 billion as of December 31, 2017 was $0.12021. The timing to fulfill performance obligations related to grant agreements will depend on the results of the Company's research and development activities, including clinical trials. The timing to fulfill performance obligations related to advance purchase agreements (“APAs”) will depend on timing of product manufacturing, delivery, and receipt of marketing authorizations. The remaining unfilled performance obligations are expected to be fulfilled in less than one year.

As of December 31, 2021, deferred revenue of $1.6 billion primarily related to upfront payments under APAs. The upfront payments are intended to assist the Company in funding investments related to building out and operating its manufacturing and distribution network, among other expenses, in support of its global supply commitment. Such upfront payments generally become non-refundable upon our achievement of certain development and commercial milestones. However, certain of the APAs may be terminated by the counterparty if the Company does not timely achieve requisite regulatory approval for NVX-CoV2373 in the relevant jurisdictions under such agreements. If the APAs were terminated, the refundable portion of the upfront payments would be repaid.

(a) U.S. government partnership formerly known as OWS

U.S. Government Partnership

In July 2020, the Company entered into a Project Agreement (the “Project Agreement”) with Advanced Technology International, Inc. (“ATI”), the Consortium Management Firm acting on behalf of the Medical CBRN Defense Consortium in connection with OWS. OWS is a partnership among components of the U.S. Department of Health and Human Services and the U.S. Department of Defense working to accelerate the development, manufacturing, and distribution of COVID-19 vaccines,
F- 25

therapeutics, and diagnostics. The Project Agreement relates to the Base Agreement the Company entered into with ATI in June 2020 (the “Base Agreement,” together with the Project Agreement, the “OWS Agreement”). The OWS Agreement requires the Company to conduct certain clinical, regulatory, and other activities, including a pivotal Phase 3 clinical trial to determine the safety and efficacy of NVX-CoV2373, and to manufacture and deliver to the U.S. government 100 million and 7.7 years, respectively. The total aggregate intrinsic value and weighted-average remaining contractual termdoses of stock options exercisablethe vaccine candidate. Funding under the OWS Agreement is payable to the Company for various development, clinical trial, manufacturing, regulatory, and other activities. The OWS Agreement contains terms and conditions that are customary for U.S. government agreements of this nature, including provisions giving the U.S. government the right to terminate the Base Agreement and/or the Project Agreement based on a reasonable determination that the funded project will not produce beneficial results commensurate with the expenditure of resources and that termination would be in the U.S. government’s interest. If the Project Agreement is terminated prior to completion, the Company is entitled to be paid for work performed and costs or obligations incurred prior to termination and consistent with the terms of the OWS Agreement. In July 2021, the U.S. government instructed the Company to prioritize alignment with the U.S. Food and Drug Administration (“FDA”) on the Company's analytic methods before conducting additional U.S. manufacturing and further indicated that the U.S. government will not fund additional U.S. manufacturing until such agreement has been made. In the third quarter of 2021, the Company updated its estimate-at-completion to reflect the impact of the change to the recognition of the fixed fee under the contract. The U.S. government also instructed the Company to proceed with work under the OWS Agreement related to all other activities, including ongoing clinical trials and nonclinical studies, regulatory interactions, analytics/assays and characterization of manufactured vaccine, and project management. In October 2021 and January 2022, the U.S. government extended the prescribed time to meet its July 2021 instructions until April 2022. The performance period under the Project Agreement extends through 2023 to cover clinical trial activities, subject to early termination by the U.S. government or extension by mutual agreement of the parties.

Under the OWS Agreement, the Company was originally entitled to receive funding of up to $1.75 billion to support certain activities related to the development of NVX-CoV2373 and the manufacture and delivery of the vaccine candidate to the U.S. government. Pursuant to the OWS Agreement, the Company is authorized to make expenditures or incur obligations of up to $1.75 billion. In August 2021, the Company's OWS agreement was amended to increase the contract ceiling by $52.9 million for a revised total of $1.8 billion. The agreement’s authorized funding remains unchanged at $1.75 billion for support of certain activities related to the development of NVX-CoV2373 and the manufacture and delivery of 100 million doses of the vaccine candidate to the U.S. government. As of December 31, 2021, the Company had recognized $1.0 billion in revenue related to the OWS Agreement since the inception of the contract, leaving $0.8 billion remaining to spend. The Company and the U.S. government will determine the timing and amounts for delivery of NVX-CoV2373 doses upon U.S authorization and the Company intends to pursue additional U.S. procurement agreements for supply of NVX-CoV2373 doses.

U.S. Department of Defense

In June 2020, the Company entered into a letter contract that was later amended in January 2021 (the “DoD Contract”) with the DoD Joint Program Executive Office for Chemical, Biological, Radiological and Nuclear Defense (“JPEO-CRBND-EB”), under which JPEO-CRBND-EB agreed to provide funding of up to $45.7 million to the Company to support the manufacture of NVX-CoV2373. Under the DoD Contract, the Company is authorized to make expenditures or incur obligations up to the full amount of the funding.

Under the DoD Contract, the Company is expected to deliver 10 million doses of NVX-CoV2373 to the DoD. The 10 million doses of NVX-CoV2373 may be used in Phase 2/3 clinical trials or under an EUA, if approved by the FDA. Pursuant to the DoD Contract, if NVX-CoV2373 is approved by the FDA, the DoD is entitled to most-favored customer status for a period of five years from the award of the DoD Contract, meaning that the Company cannot give any comparable commercial client in the United States more favorable pricing than the DoD under similar transactional circumstances.

Coalition for Epidemic Preparedness Innovations
In May 2020, the Company entered into a restated funding agreement which was amended in November 2020 (the “CEPI Funding Agreement”) with CEPI, under which CEPI agreed to provide funding of up to $399.5 million to the Company to support the development of NVX-CoV2373. The CEPI Funding Agreement provides up to $257.0 million in Grant Funding and up to $142.5 million in Forgivable Loan Funding, which are loans in the form of one or more forgivable no-interest term loans in order to prepay certain manufacturing activities and are not subject to restrictive or financial covenants. Payments received under the CEPI Forgivable Loan Funding are only repayable if the proceeds of sales to one or more third parties of NVX-CoV2373 cover the Company’s costs of manufacturing such vaccine candidate, not including manufacturing costs funded by CEPI. The Company anticipates making repayments starting in 2022.

Under the terms of the CEPI Funding Agreement, among other things, the Company and CEPI agreed on the importance of global equitable access to any vaccines produced pursuant to the CEPI Funding Agreement. Any such vaccines,
F- 26

if approved, are expected to be procured and allocated through global mechanisms under discussion as part of the Access to COVID-19 Tools (ACT) Accelerator, an international initiative launched by the World Health Organization (“WHO”), Gavi the Vaccine Alliance, CEPI, and other global non-governmental organizations and governmental leaders in 2020.

The scope and continuation of the CEPI Funding Agreement may be amended depending on ongoing developments of the COVID-19 outbreak and the success of NVX-CoV2373 relative to other third-party COVID-19 vaccine candidates or treatments. If the WHO, CEPI, or a regulatory authority having jurisdiction over a clinical trial of NVX-CoV2373 determines that a third-party product candidate has substantially greater potential than a Company vaccine product, the Company must cease its clinical trial in the relevant region, and will be reimbursed for any costs incurred as a result thereof. In addition, CEPI has the right to unilaterally terminate the CEPI Funding Agreement if CEPI reasonably determines that (i) there are material safety, regulatory, or ethical issues with the development of NVX-CoV2373, (ii) NVX-CoV2373 development should be limited in scope or terminated, (iii) the Company becomes unable to discharge its obligations under the agreement, (iv) the Company fails to meet certain milestones, or (v) the Company commits fraud or a financial irregularity.

Payments received in advance that are related to future performance are deferred and recognized as revenue when the research and development activities are performed. Cash payments received under the CEPI Funding Agreement are restricted as to their use until expenditures contemplated in the funding agreements are incurred.

Bill & Melinda Gates Foundation

In support of the Company's development of ResVax, the project name for the respiratory syncytial virus (“RSV”) vaccine candidate, in September 2015, Planthe Company entered into the grant agreement with BMGF (the “BMGF Grant Agreement”), under which it was awarded a grant totaling up to $89.1 million (the “Grant”). The Grant supported ResVax development activities, including the Company's global Phase 3 clinical trial in pregnant women in their third trimester and 2005 Planother regulatory efforts.

SK bioscience, Co., Ltd.

In February 2021, the Company finalized an expanded collaboration and license agreement with SK bioscience, Co., Ltd. ("SK bioscience") to manufacture and commercialize NVX-CoV2373 for sale to the government of Korea. Concurrently, SK bioscience finalized an APA with the Korean government to supply 40 million doses of NVX-CoV2373 to the Republic of Korea beginning in 2021. The agreement is in addition to the Company's existing manufacturing arrangement with SK bioscience entered into in August 2020. Under the collaboration agreement, SK bioscience was granted an exclusive license to develop, manufacture, and commercialize NVX-CoV2373 in the Republic of Korea. SK bioscience will pay the Company a tiered royalty in the low to middle double-digit range on the sale of NVX-CoV2373. In May 2021, the Company entered a non-binding Memorandum of Understanding with the Ministry of Health and Welfare of Korea and SK bioscience to explore further cooperation in the development and manufacturing of vaccines, including NVX-CoV2373, and to potentially explore the development of new vaccine products with SK bioscience, including COVID-19 variant vaccines and/or an influenza/COVID-19 combination vaccine. SK bioscience expanded its capacity to manufacture the antigen component of NVX-CoV2373 and, in December 2021, the Company amended the collaboration and license agreement to grant a non-exclusive license to cover Thailand and Vietnam, subject to a low to middle double-digit royalty, and for SK biosciences to supply the antigen component of NVX-CoV2373 to the Company for use in the final drug product globally, including product distributed by the COVAX Facility.
Advance Purchase Agreements (APAs)
During the years ended December 31, 2021 and 2020, the Company entered into various APAs for NVX-CoV2373. Under the terms of the Company's advance purchase agreements, government counterparties make upfront payments and have certain termination rights, or rights to reduce or cancel orders, if regulatory approval for the vaccine is not received or if supply is materially interrupted, delayed, or deferred. The Company records such upfront payments as follows (in thousands):

At December 31, 2017, the Company has provided provisional accountingprovision for theincome tax effects of enactment of the Act. The Company re-measured certain of its U.S. deferred tax assets and liabilities based on the rates at which they are expected to reverse in the future. As a result, the Company’s U.S. deferred tax balances at December 31, 2017 were revalued at the newly enacted tax rate, decreasing the net deferred tax asset (before valuation allowance) by approximately $132 million, offset by a decrease in the valuation allowance by the same amount.

The valuation allowance decreased $54.7 million during the year ended December 31, 2017 primarily due to the impact of the Act and was partially offsetamount computed by the generation of net operating losses in 2017. The valuation allowance increased by $117.7 million for the year ended December 31, 2016.

Realization of net deferred tax assets is dependent on the Company’s ability to generate future taxable income, which is uncertain. Accordingly, a full valuation allowance was recorded against these assets as of December 31, 2017 and 2016 as management believes it is more likely than not that the assets will not be realizable.

As of December 31, 2017,2021, the Company hadhas available federal, state, and foreign net operating losses of $3.2 billion, $2.8 billion, and $127.6 million, respectively, that may be applied against future taxable income. Federal net operating losses of $0.9 billion will expire in the years 2022 to 2037. The remaining $2.3 billion of federal net operating losses can be carried forward indefinitely. A portion of the foreign net operating losses will begin to expire in 2023. The Company also has research tax credits available as follows (in thousands):

  Amount 
Federal and State net operating losses expiring through the year 2037 $974,463 
Foreign net operating losses (no expiration)  52,621

Utilization of the net operating loss carryforwards and credits may be subject to an annual limitation due to prior ownership changechanges of the Company. TheAs of December 31, 2021, the Company does not expect such limitation, if any, to impact the use of the net operating losses and business tax credits.

At December 31, 2017 and 2016, the Company did not have any unrecognized tax benefits. To the extent unrecognized tax benefits are ultimately recognized, it would affect the annual effective income tax rate unless otherwise offset by a corresponding change in the valuation allowance. The Company does not expect that the amounts of unrecognized tax benefits will change significantly within the next twelve months.

The Company files income tax returns in the U.S. federal jurisdiction and in various states, as well as in Sweden.Sweden and the Czech Republic. The Company hadhas U.S. tax net operating losses and credit carryforwards that are subject to examination from 19982002 through 2017.

The Company has evaluated the positive and negative evidence bearing upon the realization of its deferred tax assets, including its history of significant losses in every year since inception and, in accordance with U.S GAAP, has fully reserved the net deferred tax asset. The Company concluded that realization of its net deferred tax assets is not more-likely-than-not to be realized as of December 31, 2021. The valuation allowance increased by $510.5 million and $139.0 million for the years ended December 31, 2021 and 2020, respectively, primarily due to the increase in net operating loss carry-forwards and research and development tax credits.
On a periodic basis, the Company reassesses the valuation allowance on its deferred income tax assets, weighing positive and negative evidence to assess the recoverability of the deferred tax assets. In 2021, the Company reassessed the valuation allowance and considered negative evidence, including its cumulative losses over the three years ended December 31, 2021, and positive evidence, including its recent regulatory authorizations for NVX-CoV2373. After assessing both the negative and positive evidence, the Company concluded that it should maintain the valuation allowance on its net operating losses and its other deferred tax assets as of December 31, 2021. The release of the valuation allowance, as well as the exact timing and the amount of such release, continue to be subject to, among other things, the Company's level of profitability, revenue growth, clinical program progression, and expectations regarding future profitability. The Company's total deferred tax asset balance subject to the valuation allowance was $1.0 billion at December 31, 2021.
The Company recognizes the effect of a tax position when it is more likely than not, based on the technical merits, that the tax position will be sustained upon examination. A reconciliation of the beginning and ending amounts of unrecognized tax benefits in the year ended December 31, 2021, 2020, and 2019 is as follows (in thousands):

Operating Leases

The Company conducts its operations from leased facilities. The operating leases for these facilities have terms expiring through 2026, unless earlier terminated bytotal amount of unrecognized tax benefits that, if recognized, would affect the Company in 2023. The leases contain provisions for future rent increases. Also, the leases obligate the Company to pay building operating costs. The Company records a deferred rent liability to account for the funding under improvement allowances and to record rent expense on a straight-line basis for these operating leases.

Future minimum rental commitments under non-cancelable leases as of December 31, 2017 (excluding commitments for the Clopper Road Lease as described below as this lease was terminated in January 2018) are as follows (in thousands):

Total rent expenses approximated $8.4 million, $7.0 million and $4.2 million for the years ended December 31, 2017, 2016 and 2015, respectively.

After re-evaluating its real estate needs, the Company amended its lease for approximately 147,000 square feet of facility space located at 1201 Clopper Road, Gaithersburg, Maryland (the “Clopper Road Lease”), allowing for, among other things, the ability to terminate the Clopper Road Lease upon the occurrence of certain events. In January 2018, the landlord terminated the Clopper Road Lease, and the Company paid a termination fee to the landlord of $5.3 million, which the Company believeseffective tax rate is less than the potential total lease and operating expense cash obligations that could have been incurred over one year. The Company expects to record total expense, which includes the termination fee and write-down of the related leasehold improvements, and is partially offset by deferred rent expense previously recorded, of approximately $1 million in the first quarter of 2018 in connection with the termination of the Clopper Road Lease.

Contingencies

In 2007, the Company entered into an agreement to license certain rights from Wyeth Holdings Corporation, a subsidiary of Pfizer Inc. (“Wyeth”). The Wyeth license is a non-exclusive, worldwide license to a family of patents and patent applications covering VLP technology for use in human vaccines in certain fields, with expected patent expiration in early 2022. The Wyeth license provides for the Company to make an upfront payment (previously made), ongoing annual license fees, sublicense payments, milestone payments on certain development and commercialization activities and royalties on any product sales. Except in certain circumstances in which the Company continuously markets multiple products in a country within the same vaccine program, the milestone payments are one-time only payments applicable to each related vaccine program. At present, CPLB’s recombinant trivalent seasonal VLP influenza vaccine (“CadiFlu”) is the only program to which the Wyeth license applies. The license may be terminated by Wyeth only for cause and may be terminated by the Company only after it has provided ninety (90) days’ notice that the Company has absolutely and finally ceased activity, including through any affiliate or sublicense, related to the manufacturing, development, marketing or sale of products covered by the license. In September 2015, the Company entered into an amendment to the license agreement with Wyeth. Among other things, the amendment restructured the $3 million milestone payment (“Milestone”) owed as a result of CPLB’s initiation of a Phase 3 clinical trial for CadiFlu in 2014. Under the amendment, the Milestone, which has increased slightly over time, became due on December 31, 2017. The amendment also restructured the final milestone payment to apply to the initial seasonal influenza VLP vaccine candidate being developed outside India. Thus, the aggregate milestone payments for a seasonal influenza VLP vaccine candidate developed and commercialized was increased from $14 million to up to $15 million. In connection with the execution of the amendment, the Company agreed to pay a one-time only payment to Wyeth. The amendment also increased annual license maintenance fees associated with VLP vaccine candidates from $0.2 million to $0.3 million per year. Payments under the agreement to Wyeth as of December 31, 2017 aggregated to $7.6 million. At December 31, 2017, the Milestone is recorded in accrued expenses on the consolidated balance sheet and is expected to be paid in the first quarter of 2018. The Milestone was recorded as a research and development expense in 2014.

Legal Matters

On February 26, 2021, a Novavax stockholder named Thomas Golubinski filed a derivative complaint against members of the Novavax board of directors and members of senior management in the Delaware Court of Chancery, captioned Thomas Golubinski v. Richard H. Douglas, et al., No. 2021-0172-JRS. Novavax is deemed a nominal defendant. Golubinski challenged equity awards made in April 2020 and in June 2020 on the ground that they were “spring-loaded,” that is, made at a time when such board members or members of senior management allegedly possessed undisclosed positive material information concerning the Company. The complaint asserted claims for breach of fiduciary duty, waste, and unjust enrichment. The plaintiff sought an award of damages to the Company, an order rescinding both awards or requiring disgorgement, and an award of attorneys’ fees incurred in connection with the litigation. On May 10, 2021, the defendants moved to dismiss the complaint in its entirety. On June 17, 2021, the Company’s stockholders voted FOR ratification of the April 2020 awards and ratification of the June 2020 awards. Details of the ratification proposals are set forth in the Company’s Definitive Proxy Statement filed with the SEC on May 3, 2021. The results of the vote were disclosed in the Company’s Current Report on Form 8-K filed with the SEC on June 24, 2021. Thereafter, the plaintiff stipulated that, as a result of the outcome of the June 17, 2021 vote, the plaintiff no longer intends to pursue the lawsuit or any claim arising from the April 2020 and June 2020 awards. On August 23, 2021, the plaintiff filed a motion seeking an award of attorneys’ fees and expenses, to which the defendants filed an opposition. The action is currently stayed, and upon final resolution of the plaintiff’s motion for an award of fees and expenses, the action will be automatically dismissed. As such, the Company is not expecting any material estimable financial impact of the plaintiff's claim.

On November 12, 2021, Sothinathan Sinnathurai filed a purported class action in the U.S. District Court for the District of Maryland against Novavax and certain members of senior management, captioned Sothinathan Sinnathurai v. Novavax, Inc., et al., No. 8:21-cv-02910-TDC (the “Sinnathurai Action”). The complaint in the Sinnathurai Action alleges that the defendants made certain purportedly false and misleading statements concerning NVX-CoV2373, including with respect to the Company’s manufacturing capabilities and NVX-CoV2373’s regulatory and commercial prospects. The purported class is defined as those who purchased or otherwise acquired Novavax securities between March 2, 2021 and October 19, 2021. The complaint demands an award of damages on behalf of the purported class and attorneys’ fees incurred in connection with the litigation. On January 26, 2022, the court entered an order designating David Truong, Nuggehalli Balmukund Nandkumar, and Jeffrey Gabbert as co-lead plaintiffs in the Sinnathurai Action. The court has ordered the co-lead plaintiffs to file an amended complaint by March 11, 2022. The Company’s response to the amended complaint is due April 25, 2022.

After the Sinnathurai Action was filed, three derivative lawsuits were filed and are currently pending in the U.S. District Court for the District of Maryland: Robert E. Meyer v. Stanley C. Erck, et al., No. 8:21-cv-02996-TDC (the “Meyer Action”), Shui Shing Yung v. Stanley C. Erck, et al., No. 8:21-cv-03248-TDC (the “Yung Action”), and William Kirst, et al. v. Stanley C. Erck, et al., No. 8:22-cv-00024-TDC (the “Kirst Action”). The derivative lawsuits name members of the board of directors and certain members of senior management as defendants. Novavax is deemed a nominal defendant. The derivative plaintiffs assert derivative claims arising out of substantially the same alleged facts and circumstances as the Sinnathurai Action. Collectively, the derivative complaints assert claims for breach of fiduciary duty, insider selling, unjust enrichment, violation of federal securities law, abuse of control, waste, and mismanagement. Plaintiffs seek declaratory and injunctive relief, as well as an award of monetary damages and attorneys’ fees. Novavax removed the Kirst Action from the Circuit Court for Montgomery County, Maryland. On February 7, 2022, the plaintiffs in the Kirst Action filed a motion to remand the action to state court and, in response, the Company has filed an opposition. The Court also entered an order tolling the managing directordefendants’ time to respond to the complaints in the Meyer and Yung Actions pending submission of Cadila. a joint proposed briefing schedule on any anticipated motion practice in those cases by March 25, 2022. On February 4, 2022, the Court entered an order consolidating the Meyer and Yung Actions. The financial impact of the claims is not estimable.

The Company is also involved in various legal proceedings arising in the normal course of business. Although the outcomes of these legal proceedings are inherently difficult to predict, management does not expect the resolution of these legal proceedings to have a material adverse effect on the Company's financial position, results of operations, or cash flows.

Purchase Commitments

The Company has entered into agreements in the normal course of business with CMOs and Cadila formed a joint venture, CPLBCDMOs supplying the Company with production capabilities, and with vendors for preclinical studies, clinical trials, and other goods or services. A number of these arrangements are within the scope of lease accounting (see Note 7). A subsidiaryCertain agreements provide for termination rights subject to termination fees. Under such agreements, the Company is contractually obligated to make payments to vendors, mainly to reimburse them for their estimated unrecoverable expenses. The exact amount of Cadila owned 2.5 million sharessuch obligations are dependent on the timing of termination, and the terms of the Company’s outstanding common stockrelevant agreement, and cannot be reasonably estimated. As of December 31, 2021, most of these agreements were active ongoing arrangements and the Company expects to receive value from these arrangements in the future. The Company recognizes fees related to obligations for terminated contracts where such fees are reasonably estimable. The Company did not accrue obligations that were not reasonably estimable.

As of December 31, 2021, the Company had 0 non-cancelable purchase commitments with a remaining term of more than one year as compared with approximately $117 million as of December 31, 2017.
