Novavax, Inc., together with our wholly-owned subsidiaries, Novavax AB and Novavax CZ, is a biotechnology company promoting improved global health through the discovery, development and commercialization of innovative vaccines to prevent serious infectious diseases and address urgent, global health needs.

Our vaccine candidates, 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 disease pathogenesis.

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.

Additionally, our Matrix-M ™ adjuvant has been shown to enhance functional immune responses and has been well-tolerated in multiple clinical trials.

To date, we have formulated many of the vaccine candidates in our pipeline with our Matrix-M ™ adjuvant, including NVX-CoV2373 and NanoFlu ™ .

Novavax, Inc., together with our wholly-owned subsidiaries, is a biotechnology company that promotes improved health globally through the discovery, development, and commercialization of innovative vaccines to prevent serious infectious diseases around the world.

Our proprietary recombinant technology platform harnesses the power and speed of genetic engineering to efficiently produce highly immunogenic nanoparticle vaccines designed to address urgent global health needs.

Our vaccine candidates are genetically engineered nanostructures of conformationally correct recombinant proteins that mimic those found on natural pathogens.

This technology enables the immune system to recognize the right target proteins from different angles and develop protective antibodies.

We believe that our vaccine technology may lead to the induction of a differentiated immune response that may be more efficacious than naturally occurring immunity or other vaccine approaches.

Our vaccine candidates also incorporate our proprietary saponin-based Matrix-M™ adjuvant to enhance the immune response and stimulate higher levels of functional antibodies and induce a cellular immune response.

We have developed a COVID-19 vaccine (“NVX-CoV2373,” “Nuvaxovid™,” “Covavax”), and are developing an influenza vaccine, a COVID-19-Influenza Combination vaccine, and additional vaccine candidates.

NVX-CoV2373 has received approval, interim authorization, provisional approval, conditional marketing authorization (“CMA”), and emergency use authorization (“EUA”) from multiple regulatory authorities globally.

In addition to COVID-19 and seasonal influenza, our other areas of focus include respiratory syncytial virus (“RSV”) and malaria.

Technology Overview

We believe our recombinant nanoparticle vaccine technology together with our proprietary Matrix-M™ adjuvant is well-suited for the development of vaccine candidates targeting a broad scope of respiratory and other emerging infectious diseases at scale.

Recombinant Nanoparticle Vaccine Technology

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 results in a highly immunogenic nanoparticle that is ready to be formulated with Matrix-M ™ adjuvant.

Matrix-M™ Adjuvant

Our Matrix-M™ adjuvant has been a key differentiator within our platform.

Our proprietary Matrix-M ™ adjuvant has demonstrated potent and well-tolerated efficacy by stimulating the entry of antigen presenting cells (“APCs”) into the injection site and enhancing antigen presentation in local lymph nodes, which in turn activates T-cell, B-cell, and APC populations, thereby boosting immune response.

Matrix-M ™ adjuvant has been shown to increase neutralizing antibodies and induce long-lasting memory B cells, which enhances B-cell immunity and recruits and increases the frequency of CD4+ and CD8+ T-cells to enhance T-cell immunity in preclinical models.

The potent immune-stimulating mechanism of action enables a lower dose of antigen required to achieve the desired immune response, ultimately contributing to increased supply and manufacturing capacity.

Our proprietary Matrix-M™ adjuvant has been a key differentiator within our platform.

This adjuvant has demonstrated potent, well-tolerated, and durable efficacy by stimulating the entry of antigen presenting cells (“APCs”) into the injection site and enhancing antigen presentation in local lymph nodes.

This in turn activates APCs, T-cell and B-cell populations, plasma cells, and high affinity antibodies, thereby boosting immune response.

This potent mechanism of action enables a lower dose of antigen required to achieve the desired immune response and we 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 TM adjuvant alongside vaccine antigens produced by other manufacturers.

Our Matrix-M ™ adjuvant is being evaluated in combination with several 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 them a license for the vaccine.

We expect to manufacture and supply the Matrix-M ™ adjuvant component of R21 to SIIPL.

We believe the use of our Matrix-M ™ adjuvant in R21 may present a significant commercial opportunity for our adjuvant, pending possible licensure.

Near-term Clinical Development Pipeline

Our development pipeline encompasses vaccine candidates addressing therapeutic areas including coronavirus, seasonal influenza, respiratory syncytial virus (“RSV”) and other emerging infectious diseases.

At the forefront of our pipeline is our COVID-19 vaccine candidate, NVX-CoV2373.

We advanced NVX-CoV2373 through two Phase 3 clinical trials, which demonstrated 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 ™ vaccine program through a Phase 3 clinical trial, which demonstrated positive top-line results and achieved statistical significance in key secondary endpoints.

We recently initiated a trial of a combination vaccine consisting of NanoFlu ™ and NVX-CoV2373 and remain interested in further development of the respiratory syncytial virus fusion (F) protein nanoparticle vaccine candidate (“RSV F Vaccine”).

RSV F Vaccine may be considered for further development.

NVX-CoV2373 Regulatory and Licensure

We continue to make progress in advancing NVX-CoV2373 toward regulatory approvals.

We have received numerous authorizations globally, which collectively have the potential to reach over six billion individuals.

To date, we have received approval, interim authorization, provisional approval, CMA, and EUA for both adult and adolescent populations, and we expect to initiate additional rolling submissions worldwide.

We continue to work closely with governments, regulatory authorities, and non-governmental organizations in our commitment to facilitate equitable global access to our COVID-19 vaccine.

For the territories in which our vaccine has gained authorization, NVX-CoV2373 is marketed under the brand name of Nuvaxovid™ COVID-19 Vaccine (SARS-CoV-2 rS [Recombinant, adjuvanted]) or as Covovax™ (manufacturing and commercialization by the Serum Institute of India Pvt.

Through the date of filing this Quarterly Report, the below is a summary of regulatory authorizations for NVX-CoV2373:

(1) Regulatory manufacturing and marketing approval received by partner Takeda Pharmaceutical Company Limited (“Takeda”).

(2) Regulatory approval received in partnership with SIIPL.

In the first quarter of 2022, we have completed additional regulatory submissions in major markets for both adult and adolescent populations.

We are in active discussions with regulatory authorities and remain focused on seeking additional authorizations for NVX-CoV2373.

Below is a summary and status of our regulatory submissions completed through the date of filing this Quarterly Report.

Clinical Pipeline

Our clinical pipeline encompasses vaccine candidates spanning multiple therapeutic areas including coronavirus, seasonal influenza, RSV, and Matrix-M TM adjuvant collaborations for the prevention of malaria.

Our COVID-19 vaccine candidate, NVX-CoV2373, is our leading product, having received approval, interim authorization, provisional approval, CMA, and EUA from multiple regulatory authorities globally.

We advanced NVX-CoV2373 through two pivotal Phase 3 clinical trials that demonstrated 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 influenza vaccine 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 COVID-19-Influenza Combination vaccine (“CIC”) consisting of our influenza vaccine and NVX-CoV2373.

In April 2022, we announced initial results from Phase 1/2 clinical trial of CIC demonstrating that formulating the combination vaccine is well-tolerated and immunogenic.

Modeling results showed that combined formulation has the potential to reduce total antigen amount by up to 50% overall, optimizing production and delivery.

Additionally, we remain interested in further 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 by our partner, Jenner Institute, University of Oxford, for R21, a malaria candidate currently under development by the University of Oxford in partnership with SIIPL, which is formulated using our Matrix-M ™ adjuvant.

We remain focused on bringing our NVX-CoV2373 vaccine candidate to market following global regulatory authorizations.

Through ongoing crossover and booster studies in our clinical trials, as well as the development of our 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 COVID-19 vaccine for both primary vaccination around the globe and to further develop a booster strategy amidst the ongoing and evolving COVID-19 pandemic.

Although NVX-CoV2373 and NanoFlu ™ are our near-term priorities, we remain optimistic that the additional programs in our pipeline, including our vaccine candidates for RSV and other emerging infectious diseases, present viable opportunities for future development.

The pipeline chart below summarizes the clinical and preclinical development programs that we are focused on in the near-term.

We will continue to evaluate areas of development focus over time.

PREVENT-19, a Phase 3 clinical trial in the U.S.

1 unchanged sentence

Phase 3 clinical trial in the UK;

NVX-CoV2373 Clinical Development

Our lead vaccine candidate, 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.

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.

Enrollment for PREVENT-19 emphasized recruiting high-risk groups most impacted by COVID-19.

In October 2021, the final analysis of our PREVENT-19 Phase 3 trial in the U.S.

and Mexico was submitted for peer review and is available ahead of publication via the preprint server on medRxiv.

The analysis, previously announced in June 2021, was conducted on events accrued prior to participants receiving crossover vaccine.

NVX-CoV2373 achieved its primary endpoint with an overall efficacy of 90.4% despite the majority (82%) of the sequenced cases of illness being attributed to Variants of Interest and VoC.

Notably, NVX-CoV2373 demonstrated 100% protection against moderate and severe disease, including those caused by variants.

PREVENT-19 was conducted with support and funding from OWS.

In August 2021, the U.S.

Centers for Disease Control and Prevention (“CDC”) provided guidance for our PREVENT-19 participants in the U.S.

stating that they meet the criteria to be considered fully vaccinated two weeks after completion of the active vaccine series.

With the CDC’s validation, we expect our participants to be considered fully vaccinated and in compliance with mandated vaccination policies.

PREVENT-19 Pediatric Expansion

In June 2021, we completed enrollment of the pediatric expansion of our PREVENT-19 Phase 3 trial in the U.S.

that was initiated in April 2021.

The pediatric expansion is a placebo-controlled trial to evaluate efficacy, safety, and immunogenicity of NVX-CoV2373 in 2,248 adolescent participants aged 12 to 17 years across up to 75 sites in the U.S.

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.

All primary and crossover doses have been administered.

Participants are being monitored for safety for up to two years following the final administered dose.

We expect to have a regulatory package available for global submission in the first quarter of 2022.

The subsequent pediatric clinical development plan has been agreed to by the FDA, MHRA and European Medicines Agency (“EMA”) and be initiated after this adolescent study reads out.

In June 2021, the final analysis of our Phase 3 UK trial was published in the New England Journal of Medicine .

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, which represents strains most similar to the original COVID-19 virus.

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 October 2021, the final analysis of our Phase 3 UK influenza co-administration sub-study was accepted by a peer-reviewed journal and is available ahead of publication via the preprint server on medRxiv.

Previously, we announced data from this sub-study in June 2021.

In this sub-study, 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.

NVX-CoV2373 Booster Studies

Novavax-Led Booster Study

In August 2021, we announced data from our six-month booster study in the Phase 2 portion of our U.S.

and Australia Phase 1/2 trial, which we initiated in March 2021.

Select participants in the 5 microgram dose cohort from the Phase 2 portion of the Phase 1/2 trial received a third 5 microgram dose (booster dose) at six months to examine the functional immune response 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.

In September 2021, we initiated a twelve-month booster dose for select participants in the Phase 2 portion of our U.S.

and Australia Phase 1/2 trial.

In this booster study, select participants in the 5 microgram dose cohort from our six-month booster study in the Phase 2 portion of the Phase 1/2 trial will receive an additional 5 microgram dose (a booster dose) at twelve months to examine the functional immune response of our vaccine candidate.

Partner-Led Vaccine Mix and Match Clinical Studies

We recognize the importance of exploring NVX-CoV2373 alongside the use of other COVID-19 vaccine manufacturers.

We continue to develop our booster strategy through our participation in multiple partner-led trials evaluating the potential for mixed vaccine regimens in primary and booster settings.

A summary and status of our participation in partner-led vaccine interchangeability trials follows:

NVX-CoV2373 Regulatory and Licensure

We have completed multiple regulatory submissions and expect to complete additional filings.

We are in constant discussions with regulatory authorities globally for our completed and anticipated submissions.

We continue to work closely with governments, regulatory authorities, and non-governmental organizations in our commitment to ensuring equitable global access to our COVID-19 vaccine.

Below is a summary and status of our regulatory processes through the date of filing this Form 10-Q.

In November 2021, in partnership with Serum Institute of India Pvt.

(“SIIPL”), we received emergency use authorization (“EUA”) from the National Agency of Drug and Food Control of the Republic of Indonesia, or Badan Pengawas Obat dan Makanan, following the August 2021 regulatory submission made by SIIPL with our support.

EUA was granted for our recombinant nanoparticle protein-based vaccine with our Matrix-M TM adjuvant, which will be manufactured and marketed in Indonesia by SIIPL under the brand name COVOVAX™.

Indonesia contracted with SIIPL for the purchase of 50 million doses of COVOVAX™.

This marks the first regulatory authorization worldwide of a protein-based COVID-19 vaccine based on Phase 3 clinical data demonstrating efficacy and a favorable safety profile.

In November 2021, we completed the rolling submission of all modules required by the EMA to support final regulatory review.

The final step to complete the application in the European Union will be an invitation from EMA to file for conditional marketing authorization ("CMA").

In October and November 2021, we completed rolling regulatory submissions in key markets for NVX-CoV2373.

We filed for CMA with the UK MHRA, leveraging our manufacturing partnership with SIIPL.

Additionally, we filed for provisional approval with Australia’s Therapeutic Goods Administration, authorization with Health Canada, and provisional approval with New Zealand Medicines and Medical Devices Authority and the WHO for emergency use listing ("EUL").

In partnership with SIIPL, in August 2021, for our COVID-19 vaccine that will be manufactured and commercialized with SIIPL, we filed regulatory submission for EUA with the Drugs Controller General of India, regulatory agencies in Indonesia and the Philippines, and EUL with the WHO.

The grant of EUL by the WHO is a prerequisite for exports to numerous countries participating in the COVAX Facility, which was established to allocate and distribute vaccines equitably to participating countries and economies.

These filings mark the first protein-based COVID-19 vaccine submitted in these markets.

In the U.S, we are in continued discussions with the FDA about submission of our investigational new drug application for NVX-CoV2373.

We continue to address and complete various Chemistry, Manufacturing and Controls ("CMC") requirements, which ensure that our manufacturing processes are in accordance with regulatory standards.

As of November 2021, we validated the potency and purity of our assays and are in the final process of testing our product using these assays.

We expect to submit the complete regulatory package to the FDA by the end of 2021.

COVID-19 Vaccine Funding

We have secured critical funding throughout 2020 and into 2021 to support the development of NVX-CoV2373.

Through the date of filing this Form 10-Q, funding for NVX-CoV2373 encompasses over $2 billion from sources including the BMGF, CEPI, the 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.

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 potentially for commercial sale, if authorized for emergency use or licensed.

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 is expected to support our plans to file submissions for EUA and licensure 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 September 30, 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.

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.

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.

A summary and status of our historical COVID-19 funding developments follows:

NVX-CoV2373 Manufacturing and Supply

We have established a global manufacturing and supply chain to support the commercialization of NVX-CoV2373.

With significant progress made throughout 2020 and through the third quarter of 2021, our global supply chain spans over ten countries and includes Novavax-owned facilities in the Czech Republic and Sweden, as well as partnerships with contract

manufacturing organizations around the world.

In the third quarter of 2021, we remained focused on readying our global supply chain for commercialization to ensure we will promptly deliver NXV-CoV2373 upon anticipated regulatory authorizations.

We have reached our global manufacturing capacity of NVX-CoV2373 of approximately 100 million doses per month as of the end of the third quarter of 2021.

We anticipate the remainder of our manufacturing capacity will be ready by the end of the fourth quarter of 2021, which we expect will support total global manufacturing capacity of approximately 150 million doses per month, including doses manufactured by our partner SIIPL.

We expect to have manufacturing capacity in excess of 2 billion annual doses in 2022.

NVX-CoV2373 Manufacturing Agreements

In October 2021, we entered into a supply agreement with SIIPL and Serum Life Sciences Limited (“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.

Following this agreement, we anticipate rapid scale-up in manufacturing of NVX-CoV2373 at Mabion’s Good Manufacturing Practice-certified facility located near Warsaw, Poland.

In September 2021, Takeda Pharmaceutical Company Limited (“Takeda”) finalized an agreement with the government of Japan’s Ministry of Health, Labour and Welfare (“MHLW”) for the purchase of 150 million doses of NVX-CoV2373.

The announcement followed a recent update from MHLW on its ongoing efforts to secure coronavirus vaccine for the citizens of Japan.

These efforts include vaccine procurement by Takeda based on technology transfer from us, with Takeda in the process of manufacturing implementation at its facility, pursuant to the terms of the collaboration and license agreement we entered into with Takeda in February 2021, 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.

Distribution of Novavax’ vaccine in Japan by Takeda is expected to begin in 2022.

Takeda anticipates the capacity to manufacture 250 million doses of NVX-CoV2373 per year.

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 will continue 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.

NVX-CoV2373 Supply Agreements

We expect our global supply chain will enable us to deliver upon our supply commitments around the world.

We have entered into advance purchase agreements (referred to as "APAs" or "supply agreements" throughout this Form 10-Q), as well as multiple supply and license agreements with strategic partners.

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 and commercial milestones.

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 were terminated, the refundable portion of the upfront payments will be repaid.

In August 2021, we executed an APA with the European Commission acting on behalf of various European Union member states, to supply a minimum of 20 million and up to 100 million initial doses of NVX-CoV2373, with the option for the European Commission to purchase an additional 100 million doses through 2023.

Seasonal Influenza

NanoFlu ™ Vaccine Program (Older Adults)

In September 2021, the final analysis of the primary endpoint of our pivotal Phase 3 clinical trial for NanoFlu TM was published in The Lancet Infectious Diseases .

We previously announced that NanoFlu TM 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, NanoFlu TM 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 ™ vaccine team remains focused on advancing combination vaccine candidates.

With the ongoing development of NanoFlu ™ , NVX-CoV2373 and our RSV F Vaccine, a strong rationale exists for developing combination respiratory vaccines designed to protect susceptible populations against these diseases.

Phase 1/2 Clinical Trial of COVID-NanoFlu™ 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 combination vaccine using NanoFlu™ 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 trial are expected in the first half of 2022.

Ongoing Phase 2b clinical trial in South Africa.

We, along with our partners, will have commercial rights in authorized geographies to sell and distribute NVX-CoV2373.

Royalties 39,941 — 39,941

Total revenue $ 178,844 $ 157,024 $ 21,820

Revenue for the three months ended September 30, 2021 was $178.8 million as compared to $157.0 million for the same period in 2020, an increase of $21.8 million.

Revenue for the three months ended September 30, 2021 was primarily comprised of revenue for services performed under the OWS Agreement and our funding agreements with CEPI (collectively, the "CEPI Funding Agreement") and royalties under our licensing arrangements.

Revenue for the three months ended September 30, 2020 was primarily comprised of revenue for services performed under the CEPI Funding Agreement.

The increase in revenue was due to increased development activities relating to NVX-CoV2373 under the OWS Agreement and royalties under our licensing arrangements, partially offset by decreased development activities under the CEPI Funding Agreement as we approach anticipated commercialization of NVX-CoV2373.

Revenue in 2021 increased significantly as compared with 2020 due to our NVX-CoV2373 program, which we anticipate will continue to be funded by OWS and CEPI and/or other revenue sources.

Further, we anticipate bringing our NVX-CoV2373 vaccine candidate to market following global regulatory approvals which, if achieved, should significantly increase revenue.

In anticipation, we have entered into various APA, as well as multiple supply and license agreements with strategic partners to supply NVX-CoV2373 in their specified territories under which we are entitled to receive royalties from the sale of NVX-CoV2373 by such partners.

Total expenses $ 485,988 $ 350,966 $ 135,022

Research and Development Expenses

In the three months ended September 30, 2021, our research and development activities were primarily focused on the development of NVX-CoV2373 and included direct external research and development expenses related to NVX-CoV2373 of $341.6 million, primarily comprised of costs related to the following:

• expenses incurred under agreements with contract research organization ("CROs") that conduct our clinical trials and third-party consultants related to the development of NVX-CoV2373;

• expenses incurred on developing and manufacturing the antigen drug substance and Matrix-M ™ components of NVX-CoV2373 under agreements that we established with third-party contract manufacturing organizations ("CMOs") and contract manufacturing and development organizations ("CDMOs");

• expenses incurred for the procurement of raw materials, laboratory supplies and equipment;

• other costs related to preclinical studies and regulatory consulting, as well as related program management activities to support our growing global operations.

Research and development expenses increased to $408.2 million for three months ended September 30, 2021 as compared to $294.1 million for three months ended September 30, 2020, an increase of $114.1 million primarily due to research and development of NVX-CoV2373, as summarized in the table below (in millions):

Three Months Ended September 30,

NVX-CoV2373 $ 341,600 $ 249,789

Other vaccine development programs 126 3

Total direct external research and development expense 343,382 252,350

Stock-based compensation expense 21,860 28,730

Facility expenses 4,983 1,914

Other expenses 1,396 143

Total research and development expenses $ 408,195 $ 294,087

For 2021, research and development expenses increased significantly over 2020 expenses due to our continued development activities for our NVX-CoV2373 program and increases in employee-related costs.

Following a potential regulatory approval of NVX-CoV2373, we expect product sales will result in certain types of costs that have been previously recorded as research and development in our Consolidated Statement of Operations to be capitalized as inventory and expensed as cost of goods sold when product is delivered.

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;

• the cost and timing of, and the ability to secure, regulatory approvals.

As a result of these uncertainties, we are unable to determine 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.

General and Administrative Expenses

General and administrative expenses increased to $77.8 million for the three months ended September 30, 2021 from $56.9 million for the same period in 2020, an increase of $20.9 million.

The increase in general and administrative expenses is primarily due to an increase in professional fees in support of our NVX-CoV2373 program.

Total expenses $ 494,679 $ 655,861 $ (161,182)

Cost of Sales

Cost of sales was $15.2 million, or 3% of product sales, for the three months ended March 31, 2022.

Prior to receiving approval, we expensed manufacturing costs as research and development expenses.

After receiving approval, we capitalize the costs of production for a particular supply chain when we determine that we have a present right to the economic benefit associated with the product.

While we tracked the quantities of our manufactured vaccine product and components, we did not track pre-approval manufacturing costs and therefore the manufacturing cost of our pre-launch inventory produced prior to approval is not reasonably determinable.

However, based on our expectations for future manufacturing costs to produce our vaccine product and components inventory, we estimate that approximately $0.7 billion of commercial inventory was expensed prior to approval.

We expect to utilize the majority of our reduced-cost inventory during 2022.

If inventory sold for the three months ended March 31, 2022 was valued at expected standard cost, adjusted cost of sales for the period would have been approximately $160 million, or 27% of product sales, an adjustment of $145 million.

The cost of sales as a percentage of product sales may fluctuate in the future as a result of changes to our customer mix or standard costs.

Research and Development Expenses

In the nine months ended September 30, 2021, our research and development activities were primarily focused on the development of NVX-CoV2373 and included direct external research and development expenses related to NVX-CoV2373 of $1.4 billion, primarily comprised of costs related to the following:

• expenses incurred under agreements with CROs that conduct our clinical trials and third-party consultants related to the development of NVX-CoV2373;

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

• expenses incurred for the procurement of raw materials, laboratory supplies and equipment;

• other costs related to preclinical studies and regulatory consulting, as well as related program management activities to support our growing global operations.

Research and development expenses increased to $1.6 billion for the nine months ended September 30, 2021 from $345.8 million for the same period in 2020, an increase of $1.2 billion, primarily due to increased development activities relating to NVX-CoV2373, as summarized in the table below (in millions):

General and Administrative Expenses

General and administrative expenses increased to $214.1 million for the nine months ended September 30, 2021 from $84.0 million for the same period in 2020, an increase of $130.1 million.

The increase in general and administrative expenses is primarily due to increased employee-related costs, primarily stock-based compensation expense, and an increase in professional fees in support of our NVX-CoV2373 program.

Research and development expenses for NVX-CoV2373 for the three months ended March 31, 2022, and March 31, 2021 included approximately $21.0 million and $22.8 million, respectively, related to the acceleration of manufacturing costs for leases that we determined were embedded in multiple manufacturing supply agreements with Contract Manufacturing Organizations (“CMOs”) and contract manufacturing and development organizations (“CDMOs”).

For 2022, we expect total research and development expenses to decrease 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.

Selling, General, and Administrative Expenses

Selling, general, and administrative expenses increased to $96.0 million for the three months ended March 31, 2022 from $63.2 million for the same period in 2021, an increase of $32.8 million.

The increase in selling, general, and administrative expenses is primarily due to an increase in professional fees in support of our NVX-CoV2373 program.

The change in net income (loss) was primarily due to the commencement of commercial sales of NVX-CoV2373, partially offset by decreased revenue under the OWS Agreement.

The increase in weighted average shares outstanding for the three months ended March 31, 2022 is primarily a result of sales of our common stock and exercises of stock-based awards in 2022 and 2021.

Liquidity Matters and Capital Resources

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 CDMO agreements, the progress of preclinical studies and clinical 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 developing other vaccines and product candidates, such as our NanoFlu ™ vaccine candidate and potential combination vaccines candidates, which are in various stages of development.

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 and progress of our preclinical studies and clinical trials related to other research and development activities.

We have entered into APAs or supply agreements with Gavi, the European Commission, and various countries globally that, if our COVID-19 vaccine candidate is approved, are expected to result in the delivery of approximately 570 million doses of NVX-CoV2373.

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.

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 agreement, we received an upfront payment of $350 million from Gavi during the second quarter of 2021 and expect to receive an additional payment of $350 million if we secure EUL for NVX-CoV2373 by the WHO.

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 the three and nine months ended September 30, 2021, we received royalties of $39.9 million and $63.4 million, respectively, under these licensing arrangements.

In the nine months ended September 30, 2021, we funded our operations with cash and marketable securities on hand, upfront payments under APAs, proceeds from the sale of common stock together with revenue under the OWS 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, revenue under our OWS Agreement and CEPI Funding Agreement, and following any potential global regulatory approvals, revenue from product sales, royalties under licensing arrangements with our strategic partners and/or other potential funding sources.

As of September 30, 2021, we had $1.9 billion in cash and cash equivalents, marketable securities and restricted cash as compared to $806.4 million as of December 31, 2020.

These amounts consisted of $1.9 billion in cash and cash equivalents and $9.8 million in restricted cash as of September 30, 2021, as compared to $553.4 million in cash and cash equivalents, $157.6 million in marketable securities and $95.3 million in restricted cash as of December 31, 2020.

The following table summarizes cash flows for the nine months ended September 30, 2021 and 2020 (in thousands):

Our future capital requirements depend on numerous factors including, but not limited to, revenue from our product sales and royalties under licensing arrangements with our strategic partners;

funding under our grant agreements;

our projected activities related to the development and commercial support of NVX-CoV2373 and variant candidates, including significant commitments under various CRO, CMO, and CDMO agreements;

the progress of preclinical studies and clinical 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 developing other vaccines and product candidates, such as our influenza vaccine candidate and potential combination vaccines candidates, which are in various stages of development.

We have entered into supply agreements, sometimes referred to as APAs, with Gavi, the Vaccine Alliance (“Gavi”);

the European Commission;

and various countries globally.

We also have grant and license agreements.

As of March 31, 2022, 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 license agreements, was approximately $7 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, receipt of US marketing authorization, and delivery of doses.

The timing to fulfill performance obligations related to supply agreements will depend on timing of product manufacturing, receipt of marketing authorizations, and delivery of doses.

The 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, and are applied to billings upon delivery of NVX-CoV2373.

Such upfront payments generally become non-refundable upon our achievement of certain development, regulatory, and commercial milestones.

Certain of the supply agreements may be terminated by the counterparty in the event we fail to achieve requisite regulatory approval for NVX-CoV2373 in relevant jurisdictions within established time periods.

Failure to successfully develop and commercialize NVX-CoV2373 and failure to meet regulatory milestones or product volume or delivery timing obligations under our supply agreements may require us to refund significant portions of the prepayments or reduce payments, which could have a material and adverse effect on our financial condition.

In addition, we continue to assess our manufacturing needs and intend to modify our global manufacturing footprint consistent with our contractual obligations to supply, and anticipated demand for, NVX-CoV2373, and in doing so recognize that significant costs may be incurred.

Under the terms of our contracted supply commitment with Gavi, which includes the supply obligation of our licensed partner, SIIPL, 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.

The Novavax portion is a supply agreement that contemplates that we will manufacture and distribute 350 million doses.

Under that agreement with Gavi, we received an upfront payment of $350 million from Gavi in 2021 and an additional payment of $350 million in the first quarter of 2022 related to our achieving WHO EUL.

Although Novavax is prepared to deliver the quantities of NVX-CoV2373 doses to Gavi under the terms of our supply agreement, we were recently notified by Gavi of their intent to seek to revise the number and timing of doses of NVX-CoV2373 supplied by Novavax under such agreement.

To date, Novavax has not received an order from Gavi and the timing and quantities of future orders to deliver NVX-COV2373 to the COVAX facility are unclear.

We have also entered into supply and license agreements with strategic partners, such as SIIPL in India, Takeda in Japan, and SK bioscience in the Republic of Korea, that allow them to supply NVX-CoV2373 in their specified territories and under which we are entitled to receive royalties primarily from their sales of NVX-CoV2373.

During the three months ended March 31, 2022, we recognized royalties of $7.4 million under these licensing arrangements.

In the three months ended March 31, 2022, we primarily funded our operations with cash and cash equivalents, upfront payments under APAs, revenue from product sales, royalties under licensing arrangements with our strategic partners, and proceeds from the sale of common stock together with revenue under the OWS Agreement that supports our NVX-CoV2373 vaccine development activities.

We anticipate our future operations to be funded by revenue from product sales, royalties under licensing arrangements with our strategic partners, our cash and cash equivalents, upfront payments under our APAs, revenue under our OWS Agreement, and other potential funding sources.

As of March 31, 2022, we had $1.6 billion in cash and cash equivalents and restricted cash as compared to $1.5 billion as of December 31, 2021.

The following table summarizes cash flows for the three months ended March 31, 2022 and 2021 (in thousands):

2022 2021 Change

7 unchanged sentences

Cash, cash equivalents, and restricted cash at end of period $ 1,584,100 $ 2,029,070 $ (444,970)

Net cash provided by operating activities increased to $665.4 million for the nine months ended September 30, 2021, as compared to $86.0 million for the same period in 2020.

The increase in cash provided is primarily due to payments under APAs recorded as deferred revenue, partially offset by funding of our increased net loss and the timing of payments to third parties.

During the nine months ended September 30, 2021 and 2020, our investing activities consisted primarily of maturities and sale of marketable securities, net of purchases, our acquisition of Novavax CZ in 2020 and, to a much lesser extent, capital expenditures.

Capital expenditures for the nine months ended September 30, 2021 and 2020 were $41.1 million and $12.6 million, respectively, and the increase in capital expenditures was primarily due to the build out of our facilities and related capital expenditures to support NVX-CoV2373.

For 2021, we expect our capital expenditures to continue to increase due to further development activities for our NVX-CoV2373 program, including the additional build-out of research and development and manufacturing facilities and related equipment, and the build-out of our new corporate office facility to accommodate anticipated increases in headcount.

Net cash used in operating activities was $88.5 million for the three months ended March 31, 2022, as compared to net cash provided by operating activities of $663.1 million for the same period in 2021.

The decrease in cash provided is primarily due to the application of upfront payments under APAs resulting from sales of NVX-CoV2373 during the three months ended March 31, 2022 as compared to an increase in cash due to the receipt of upfront payments under APAs during the three months ended March 31, 2021.

During the three months ended March 31, 2022 and 2021, our investing activities consisted primarily of capital expenditures and maturities and sale of marketable securities, net of purchases.

Capital expenditures for the three months ended March 31, 2022 and 2021 were $16.8 million and $13.8 million, respectively.

For 2022, we expect our capital expenditures to continue to increase due to further development activities for our NVX-CoV2373 program, including the additional build-out of research and development and manufacturing facilities and related equipment, and the build-out of our new corporate office facility.

Our financing activities consisted primarily of sales of our common stock under our At Market Issuance Sales Agreements, payments of finance lease liabilities, and exercise of stock-based awards.
