2023 Annual Report

A Message from Our CEO

 APRIL 22, 2024

To Our Shareholders,

Following my first full year at Novavax, I look back at the tremendous progress made in 2023 and 

am even more excited about the future of our company. We navigated a dynamic COVID-19 

landscape while successfully delivering our protein-based non-mRNA COVID-19 vaccine, Nuvaxovid™, 

to people around the world. We continued to achieve significant progress against our strategic 

priorities,  meaningfully  improved  our  financial  profile  and  directed  resources  to  support  the 

expansion  of  our  pipeline.  We  have  made  difficult  but  important  changes  that  help  to  position 

Novavax for long-term, sustainable growth. Reflecting on this past year, I’m proud of the strides we 

have taken to strengthen our business and better position us to achieve our goals in 2024 and beyond.

Our Opportunity and Focus on the Future 

As we look to the remainder of the year, we will maintain focus on three priorities which we believe are the most critical for our business        

as we work to expand our impact on global public health and deliver results for our stakeholders:

Deliver an updated COVID-19 vaccine for the 2024-2025 vaccination season

Our top near-term priority is delivering an updated vaccine aligned with public health recommendations and with a more 

compelling presentation for the fall, which marks the start of the 2024-2025 vaccination season in the Northern Hemisphere. In the 

U.S., we are setting the stage for expanded availability and a stronger commercial performance, with plans for regulatory action

and market availability for the start of the season, vaccine presentation in pre-filled syringes, and the ability to leverage established 

relationships with top retailers, who drove 90% of the business last season. We are continuing to closely partner with the U.S. Food and 

Drug Administration (FDA) and other regulatory agencies around the world as we prepare for strain selection. Outside of the U.S., we 

are prepared to transition to the commercial market, and we have prioritized and focused our efforts on select key countries. Finally, 

we will continue to focus on delivery against our advance purchase agreement commitments throughout the APAC region.

Independently launch a Phase 3 trial of our COVID-19-Influenza-Combination (CIC)

vaccine candidate in the second half of 2024

As we work to expand beyond a one-product company and maximize the value of our scientific platform, we are most immediately 

focused on bringing our CIC vaccine candidate to market. We are on track to initiate our Phase 3 trial in the second half of 2024. 

We continue to have productive interactions with the FDA, including agreement on the design of our Phase 3 program as well as a 

regulatory pathway for accelerated approval. Additionally, we are planning a lot-to-lot consistency trial in the fourth quarter of 

2024, which should put us on track for regulatory filing in 2025 and potential launch as early as the 2026-2027 vaccination season.

Continue the evolution of Novavax, further reducing operating expenses

In line with last year, we are continuing to scale our organization appropriately and reduce our spend to better align with the 

evolving market opportunity. Our disciplined approach has enabled us to exceed prior cost-cutting guidance and maintain 

efficient operations to ensure smart deployment of our resources. This approach is a key lever to improving the financial health 

and performance of Novavax to enable long-term value creation.

In summary, our focus in 2024 on these objectives should enable us to further strengthen Novavax’s opportunity to drive enhanced 

value creation, as we strive to evolve into a leading global vaccine innovator. As we continue to become a more lean and agile 

organization, we are focused on improving long-term commercial performance in the COVID-19 market and advancing our CIC 

vaccine candidate towards a potential launch in the 2026-2027 vaccination season.

The  successful  execution  of  these  priorities  is  not  possible  without  our  employees,  who  I  want  to  thank  for  their  contributions  that 

continue to advance our science and business while supporting our mission.

Finally, to our shareholders, thank you for your continued support.

We remain committed to our work and delivering returns on your investment.

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 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  -  Vaccine  remains  uncertain.  While  we  have 
received  full  marketing  authorization  provisional  registration,  conditional  marketing  authorization 
(“CMA”),  or  emergency  use  authorization  (“EUA”)  for  our  prototype  COVID-19  Vaccine  and  our 
updated COVID-19 vaccine in a number of jurisdictions, we may be unable to obtain full regulatory 
approvals in the United States (“U.S.”) or other jurisdictions for our updated vaccine or new versions 
in the future, or produce a successful vaccine in a timely manner, if at all. 
The emergence and transmissibility of variants of the SARS-CoV-2 virus, and the demand for bivalent 
vaccines, may affect market acceptance or sales of our COVID-19 Vaccine, and our strategy to 
develop  new  versions  of  our  COVID-19  Vaccine  to  protect  against  certain  variants  may  not  be 
successful. 

•  We  are  a  biotechnology  company  and  face  significant  risk  in  developing,  manufacturing,  and 

commercializing our products and product candidates. 

• 

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 and product candidates.

•  We are highly dependent on the commercial success of our COVID-19 Vaccine, and even though 
we  have  received  provisional  registration,  CMA,  or  EUA  or  full  marketing  authorization  in  certain 
jurisdictions for our COVID-19 Vaccine, and even if we have products licensed in additional markets, 
our vaccine products may not be initially or ever profitable. 

• 

The  risks  associated  with  COVID-19  and  related  governmental  public  health  policies  continue  to 
evolve,  which  may  have  unpredictable  effects  on  the  prospects  for  commercial  success  of  our 
COVID-19 commercial program. 

•  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 and a combined 
vaccine against COVID-19 and influenza, and we may never see returns on the significant resources 
we are devoting to our vaccine candidates. 

•  We may not succeed in obtaining full U.S. Food and Drug Administration (“U.S. FDA”) licensure or 

foreign regulatory approvals necessary to sell our vaccine candidates. 

•  Our product candidates might fail to meet their primary endpoints in clinical trials, meaning that we 

will not have the clinical data required to support full regulatory approvals. 

• 

The regulatory pathway for our COVID-19 Vaccine is continually evolving, and such evolution 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 our COVID-19 Vaccine at sites outside the U.S. and the U.S. 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. 

•  Given our current cash position and cash flow forecast, and significant uncertainties related to 2024 
revenue, substantial doubt exists regarding our ability to continue as a going concern through one 
year from the date that the financial statements included in this Annual Report were issued. 

• 

• 

Servicing our 5.00% convertible senior unsecured notes due 2027 (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.

Item 1.  BUSINESS 

Overview 

PART I 

Novavax,  Inc.,  together  with  our  wholly  owned  subsidiaries,  is  a  biotechnology  company  that 
promotes  improved  global  health  through  the  discovery,  development,  and  commercialization  of 
innovative  vaccines  to  prevent  serious  infectious  diseases.  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 nanostructures of conformationally correct recombinant proteins that 
mimic those found on pathogens. This technology enables the immune system to recognize target proteins 
and  develop  protective  immune  responses.  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,  stimulate  higher  levels  of  functional 
antibodies, and induce a cellular immune response. 

We  have  developed  an  updated  COVID-19  vaccine  for  the  2023-2024  vaccination  season.  In 
October  2023,  the  U.S.  FDA  granted  EUA  for  our  updated  vaccine  for  active  immunization  to  prevent 
COVID-19. The updated vaccine is authorized as (1) a single dose in individuals 12 years and older who 
have been vaccinated with any COVID-19 vaccine at least 2 months after receipt of the last previous dose 
of COVID-19 vaccine, and (2) a series of 2 doses administered 3 weeks apart to individuals 12 years and 
older who were not previously vaccinated with any COVID-19 vaccine. Our updated vaccine is available 
within the U.S. at many major pharmacy retailers. Outside the U.S. for our updated vaccine, in January 2024, 
we  were  granted  marketing  authorization  by  the  United  Kingdom’s  (“UK”)  Medicines  and  Healthcare 
Products Regulatory Agency (“MHRA”), in December 2023, we were granted expanded authorization by 
Health Canada, and in October 2023, we were granted approval by the European Commission (“EC”). We 
are committed to supplying of our key target markets through advance purchase agreements (“APAs”) 
covering  such  markets.  We  continue  to  work  closely  with  regulatory  authorities  in  many  jurisdictions  for 
authorization  of  our  updated  vaccine.  We  previously  developed a  prototype  COVID-19 vaccine,  which 
has  received  full  marketing  authorization  (“MA”),  marketing  approval,  interim  authorization,  provisional 
approval, CMA, from multiple regulatory authorities in over 40 countries globally. We continue to progress 
our  regulatory  authorizations  for  our  prototype  vaccine  in  select  territories,  as  we  believe  these  may 
facilitate authorization of our vaccine candidates for updated strains in the future. 

Additionally, we are developing a COVID-19 Influenza Combination (“CIC”) vaccine candidate. 
Our other areas of focus include providing Matrix-M™ adjuvant for collaborations, including in R21/Matrix-
M™ adjuvant malaria vaccine, which in December 2023 received prequalification from the World Health 
Organization (“WHO”) and previously received authorization in several countries, as well as other preclinical 
vaccine  research  with  our  Matrix-M™  adjuvant,  including  through  a  partnership  with  the  Bill  &  Melinda 
Gates Medical Research Institute. 

We  were  incorporated  in  1987  under  the  laws  of  the  State  of  Delaware.  Our  principal  executive 
offices  are  located  at  700  Quince  Orchard  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.” 

Technology Overview 

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

Recombinant Nanoparticle Vaccine Technology 

Once  a  target  of  interest  has  been  identified,  the  genetic  sequence  encoding  the  antigen  is 
selected  for  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  (“Sf-/BV”)  insect  cell-expression  system,  which  enables  efficient,  large-scale 
expression of the optimized protein. The Sf-/BV system produces protein-based antigens that are properly 
folded  and  modified—which  can  be  critical  for  functional,  protective  immunity.  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 proprietary Matrix-M™ adjuvant has been a key differentiator within our platform. This adjuvant 
has enabled 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, and plasma cells, which promotes the production of high-
affinity antibodies. This potent mechanism of action enables a lower dose of antigen to achieve the desired 
immune response, thereby contributing 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™  adjuvant  is  being  evaluated  in 
combination with several partner-led malaria vaccine candidates, including the R21/Matrix-M™ adjuvant 
malaria vaccine created by the Jenner Institute, University of Oxford. The R21/Matrix-M™ adjuvant vaccine 
has been licensed to Serum Institute of India Pvt. Ltd. (“SIIPL”) for commercialization and in December 2023 
received prequalification by the WHO, along with authorizations received earlier in the year in Burkino Faso, 
Ghana, and Nigeria. Additionally, in May 2023, we entered into a 3-year agreement with the Bill & Melinda 
Gates Medical Research Institute to provide our Matrix-M™ adjuvant for use in preclinical vaccine research. 
In June 2023, we signed a material transfer agreement with SK bioscience Co., Ltd. (“SK”) for use of our 
Matrix-M™  adjuvant  in  preclinical  vaccine  experiments  for  shingles,  influenza,  and  pan-sarbecovirus 
vaccine.  Our  adjuvant  technology  is  also  being  used  by  commercial  partners  as  a  key  component  in 
veterinary vaccines  against  equine influenza  and Strangles,  as  well  as  the manufacture  of  black-widow 
anti-venom. 

COVID-19 Vaccine Regulatory and Licensure 

We have received full authorizations in select territories for our prototype vaccine developed for the 
2022-2023 COVID-19 vaccination season and continue to receive authorizations for our updated vaccine 
developed  for  the  2023-2024  COVID-19  vaccination  season  in  accordance  with  the  updated  strain 
protocol  guidance.  We  continue  to  progress  our  regulatory  authorizations  for  our  prototype  vaccine  in 
select territories, as we believe these may facilitate authorization of our vaccine candidates for updated 
strains in the future. Additionally, we progress our regulatory authorizations for our updated vaccine and 
plan to continue to do so for subsequent future variant strains for each annual respiratory season. 

Within the U.S. market, our updated vaccine received EUA in October 2023 from the U.S. FDA to 
prevent COVID-19 in individuals aged 12 and older. Our updated vaccine is marketed in the U.S. under the 
name  Novavax  COVID-19  Vaccine,  Adjuvanted  (2023-2024  Formula).  The  formulation  for  our  updated 
vaccine  aligns  with  global  harmonized  guidance  from  the  U.S.  FDA,  the  European  Medicines  Agency 
(“EMA”), and WHO recommendations for the 2023-2024 vaccination season. In September 2023, the U.S. 
Centers  for  Disease  Control  and  Prevention  (“CDC”)  Advisory  Committee  on  Immunization  Practices 
(“ACIP”)  voted  in  favor  of  a  recommendation  for  the  use  of  2023-2024  monovalent  XBB  containing 
COVID-19  vaccines  authorized  under  EUA  or  approved  by  Biologics  License  Application  (“BLA”)  in 
individuals 6 months and older, which was adopted by the CDC Director. The U.S. FDA’s grant of EUA and 
CDC’s September 2023 recommendation makes our updated vaccine the only protein-based non-mRNA 

11

 
 
 
 
 
 
 
 
 
COVID-19 vaccine available in the U.S. 

Outside  of  the  U.S.  market,  we  continue  to  progress  regulatory  authorizations  for  our  updated 
vaccine globally. We highlight as follows our fourth quarter 2023 and subsequent authorizations received 
through the date of filing this Annual Report on Form 10-K. 

In  January  2024,  we  were  granted  marketing  authorization  by  the  UK  MHRA  for  our  updated 

vaccine, marketed under the name Nuvaxovid™ XBB.1.5 Vaccine, in individuals aged 12 and older. 

In December 2023, we were granted expanded authorization by Health Canada and EUA by the 
Taiwan Food and Drug Administration for our updated vaccine, marketed under the name Nuvaxovid™ 
XBB.1.5 Vaccine, in individuals aged 12 and older. 

In  November  2023,  our  updated  vaccine  received  EUA  in  South  Korea  where  SK  bioscience  has 
exclusive  commercial  rights  to  our  updated  vaccine.  Additionally,  in  November  2023,  we  were  granted 
emergency  use  license  (“EUL”)  by  the  WHO  for  our  updated  vaccine,  marketed  under  the  name 
Nuvaxovid™  XBB.1.5  Vaccine,  in  individuals  aged  12  and  older.  The  EUL  assists  WHO  member  states  in 
assessing vaccines with the aim of expediting availability and enables the WHO’s 194 member states to 
expedite regulatory approvals to import and administer the vaccine. 

In October 2023, we were granted approval by the EC for our updated vaccine in individuals aged 
12 and older, which followed the positive opinion for approval from the Committee for Medicinal Products 
for Human Use of the EMA. We expect to deliver doses to European countries pursuant to existing APAs. 

We have previously received authorizations for our prototype COVID-19 vaccine in over 40 countries 
globally including from major regulatory agencies such as the U.S. FDA, WHO, EMA, and MHRA. To date, 
we have received full MA, approval, interim authorization, provisional approval, CMA, and EUA for the adult 
population,  aged  18  and  older,  the  adolescent  population,  aged  12  to  17  years,  and  the  pediatric 
population, aged 7 to 11 years in select territories. The regulatory authorizations for our prototype vaccine 
include primary series and both homologous and heterologous booster indications within specific countries. 
For  the  territories  in  which  our  vaccine  has  received  regulatory  authorizations,  our  prototype  vaccine  is 
marketed  under  the  names  (i)  Nuvaxovid™  (SARS-CoV-2  rS  Recombinant,  adjuvanted),  (ii)  Covovax™ 
(manufacturing and commercialization by SIIPL), or (iii) Novavax COVID-19 Vaccine, Adjuvanted.  

In  October  2023,  our  prototype  vaccine  received  full  marketing  authorization  in  the  UK  from  the 
MHRA  in  individuals  aged  12  and  older,  full  approval  in  Singapore  from  Singapore’s  Health  Sciences 
Authority in individuals aged 12 and older, full registration in Australia from Australia’s Therapeutic Goods 
Administration as a booster in individuals aged 12 and older, and authorization in the EU from EMA for use 
as a booster in adolescents aged 12 through 17 years. We believe these authorizations for our prototype 
vaccine may facilitate authorizations of our vaccine candidates for our COVID-19 vaccine strain updates 
in the future. 

We  are  working  to  continue  to  expand  our  label  for  heterologous  boosting  in  adults  and 
adolescents,  to  expand  our  label  for  primary  and  re-vaccination  in  younger  children,  and  to  achieve 
supportive  policy  recommendations  enabling  broad  market  access.  We  continue  to  work  closely  with 
governments, regulatory authorities, and non-governmental organizations in our commitment to facilitate 
global access to our COVID-19 vaccine. 

APAs 

We have entered into APAs (also referred to as “supply agreements” throughout this Annual Report 
on  Form  10-K)  with  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 currently have approximately $2 billion in committed APAs anticipated for 

12

 
 
 
 
 
 
 
 
 
 
 
 
future delivery. 

We had an APA with the EC, acting on behalf of various European Union member states to supply 
a minimum of 20 million and up to 100 million initial doses of prototype vaccine, with the option for the EC 
to purchase an additional 100 million doses up to a maximum aggregate of 200 million doses in one or more 
tranches through 2023. In 2022, we were notified by the EC that it was cancelling approximately 7 million 
doses of its prior commitment originally scheduled for delivery in the first and second quarters of 2022, in 
accordance with the APA, and reducing the order to approximately 63 million doses. In January 2023, we 
finalized a revised delivery schedule for the remaining 20 million committed doses under the APA that were 
originally scheduled for delivery during the first and second quarters of 2022. The APA expired in August 2023 
and required that any open and outstanding orders from European Union member states be satisfied by 
February 2024. Since August 2023, any additional doses have been managed by amending outstanding 
orders with deliveries made by February 2024.  

We  have  an  APA  with  the  Commonwealth  of  Australia  for  the  purchase  of  doses  of  COVID-19 
Vaccine (the “Australia APA”). In April 2023, we amended the Australia APA to reduce the number of doses 
to be delivered with a commensurate increase in the per-dose price, such that the total contract value of 
the Australia APA is maintained with doses to be delivered through 2024. In May 2023, we extended a credit 
for certain doses delivered in 2022 to Australia that qualified for replacement under the Australia APA. This 
credit is the result of a single lot sold to the Australian government that upon pre-planned 6-month stability 
testing was found to have fallen below the defined specifications and the lot therefore was removed from 
the market. The credit will be applied against the future sale of doses to Australia. In July 2023, we amended 
the Australia APA to provide for replacement doses and to extend the delivery schedule through 2025. As 
of  February  2024,  we  had  not  yet  received  Therapeutic  Goods  Administration  (“TGA”)  authorization  or 
delivered  doses  as  contemplated  in  the  July  2023  amendment  and  are  in  active  discussions  with  the 
Australian government on both the TGA authorization and delivery of the doses previously scheduled for 
the fourth quarter of 2023. In February 2024, we received notice from the Australian government purporting 
to cancel its order for such prototype vaccine doses. We believe the cancellation was not proper under 
the amended Australia APA. However, if such a cancellation were determined to be allowable, $6.0 million 
of the deferred revenue would become a credit towards future deliveries of doses and approximately $48 
million of the contract value related to future deliverables would no longer be available. 

We  have  an APA with  His  Majesty  the King  in  Right  of  Canada  as  represented by  the  Minister  of 
Public  Works  and  Government  Services,  as  successor  in  interest  to  Her  Majesty  the  Queen  in  Right  of 
Canada,  as  represented  by  the  Minister  of  Public  Works  and  Government  Services  (the  “Canadian 
government”),  for  the  purchase  of  doses  of  COVID-19  Vaccine  (the  “Canada  APA”).  In  April  2023,  we 
amended the Canada APA, pursuant to which the Canadian government forfeited certain doses originally 
scheduled for delivery in 2022 for a payment of $100.4 million, which we received in the second quarter of 
2023.  In  June  2023,  we  entered  into  an  additional  amendment  (the  “June  2023  Amendment”)  to  the 
Canada APA. Pursuant to the June 2023 Amendment, (i) the Canadian government forfeited certain doses 
of COVID-19 Vaccine previously scheduled for delivery and agreed to pay a total amount of $349.6 million 
to us in two equal installments, which total amount equaled the remaining balance owed by the Canadian 
government with respect to such forfeited vaccine doses, (ii) the amount of doses of COVID-19 Vaccine 
due for delivery was reduced, (iii) the delivery schedule for the remaining doses of COVID-19 Vaccine to 
be  delivered  was  revised,  and  (iv)  the  parties  agreed  Novavax  would  use  the  Biologics  Manufacturing 
Centre  (“BMC”)  Inc.  to  produce  bulk  antigen  for  doses  in  2024  and  2025.  The  June  2023  Amendment 
maintained the total contract value of the original Canada APA. The first Installment of $174.8 million was 
payable upon execution of the June 2023 Amendment and received by Novavax in July 2023, and the 
second installment of $174.8 million was contingent and payable upon the delivery of vaccine doses in the 
second half of 2023 and received by Novavax in January 2024. The Canadian government may terminate 
the Canada APA, as amended, if we fail to receive regulatory approval for our COVID-19 Vaccine using 
bulk antigen produced at BMC on or before December 31, 2024. Our 2024 plans do not currently anticipate 
the submission for regulatory approval of our COVID-19 Vaccine using bulk antigen produced at BMC, and 
we plan to work with the Canadian government on an amendment that addresses possible alternatives, 
which may not be achievable. As of December 31, 2023, $102.8 million was classified as short-term Deferred 
revenue and $485.3 million was classified as long-term Deferred revenue with respect to the Canadian APA 

13

 
 
 
 
 
on our consolidated balance sheet. If the Canadian government terminates the Canada APA, $28.0 million 
of the deferred revenue would become refundable and approximately $224 million of the contract value 
related  to  future  deliverables  would  no  longer  be  available  (see  Note  3  to  our  consolidated  financial 
statements). In the event that the contract is terminated, we would consider competing in the Canadian 
commercial market. Pursuant to the June 2023 Amendment, Novavax and the Canadian government will 
endeavor to expand the previously agreed in-country commitment to Canada and to further partner to 
provide health, economic, and future pandemic preparedness benefits to Canada, which value may be 
provided through a number of activities, including without limitation, capital investments, the performance 
of activities or services, or the provision of technology or intellectual property licenses. Further, the parties 
will endeavor to enter into a memorandum of understanding (the “MOU”) to illustrate our ability to deliver 
such benefits over a 15-year period with an aggregate value of not less than 100% of the amount remaining 
to  be  paid  under  the  June  2023  Amendment  and  ultimately  received  by  us.  As  of  December  31,  2023, 
discussions regarding the MOU were ongoing. We agreed to hold $20.0 million of the second installment 
payment received in January 2024 in escrow for the benefit of the Canadian government, which amount 
is the sole recourse available to the Canadian government in the event of non-performance under the 
MOU.  

In July 2022, we entered into an Amended and Restated SARS-CoV-2 Vaccine Supply Agreement 
(as  amended  on  September  26,  2022,  the  “Amended  and  Restated  UK  Supply  Agreement”)  with  The 
Secretary  of  State  for  Business,  Energy  and  Industrial  Strategy  (as  assigned  to  the  UK  Health  Security 
Agency), acting on behalf of the government of the United Kingdom of Great Britain and Northern Ireland 
(the “Authority”), which amended and restated in its entirety the SARS-CoV-2 Vaccine Supply Agreement, 
dated October 22, 2020, between the parties (the “Original UK Supply Agreement”). Under the Original UK 
Supply Agreement, the Authority agreed to purchase 60 million doses of prototype vaccine and made an 
upfront payment to us. Under the terms of the Amended and Restated UK Supply Agreement, the Authority 
agreed to purchase a minimum of 1 million doses and up to an additional 15 million doses (the “Conditional 
Doses”)  of  prototype  vaccine,  with  the  number  of  Conditional  Doses  contingent  on,  and  subject  to 
reduction based on, our timely achievement of supportive recommendations from the Joint Committee on 
Vaccination and Immunisation (the “JCVI”) that is approved by the UK Secretary of State for Health, with 
respect to use of the vaccine for (a) the general adult population as part of a SARS-CoV-2 vaccine booster 
campaign  in  the  United  Kingdom  or  (b)  the  general  adolescent  population  as  part  of  a  SARS-CoV-2 
vaccine booster campaign in the United Kingdom or as a primary series SARS-CoV-2 vaccination, excluding 
where that recommendation relates only to one or more population groups comprising less than one million 
members in the United Kingdom. If the Authority did not purchase the Conditional Doses or if the number 
of such Conditional Doses was reduced below 15 million doses of prototype vaccine, we would have to 
repay up to $225 million related to the upfront payment previously received from the Authority under the 
Original UK Supply Agreement. Under the Amended and Restated UK Supply Agreement, the Authority also 
has the option to purchase up to an additional 44 million doses, in one or more tranches, through 2024. 

As of November 30, 2022, the JCVI had not made a supportive recommendation with respect to 
prototype  vaccine,  thereby  triggering,  under  the  terms  of  the  Amended  and  Restated  UK  Supply 
Agreement, (i) a reduction of the number of Conditional Doses from 15 million doses to 7.5 million doses, 
which reduced number of Conditional Doses were contingent on, and subject to further reduction based 
on,  our  timely  achievement  by  November  30,  2023  of  a  supportive  recommendation  from  JCVI  that  is 
approved  by  the  UK  Secretary  of  State  for  Health  as  described  in  the  paragraph  above,  and  (ii)  an 
obligation  for  us  to  repay  $112.5  million  related  to  the  upfront  payment  previously  received  from  the 
Authority under the Original UK Supply Agreement. In April 2023, we repaid the $112.5 million related to the 
November  30,  2022  triggering  event.  As  of  November  30,  2023,  the  JCVI  had  not  made  a  supportive 
recommendation with respect to the prototype vaccine, thereby triggering a reduction in the number of 
Conditional Doses from 7.5 million doses to zero. As of February 2024, the Company is in discussions with the 
Authority regarding the treatment of the remaining upfront payment previously received of $112.5 million, 
which is reflected in Other current liabilities.  

In May 2021, we entered into an APA with Gavi, the Vaccine Alliance (“Gavi” and “the Gavi APA”). 
Under the terms of the Gavi APA and a separate purchase agreement between Gavi and SIIPL, 1.1 billion 
doses of the prototype vaccine were to be made available to countries participating in the COVAX Facility, 

14

 
 
 
 
 
which  was  established  to  allocate  and  distribute  vaccines  equitably  to  participating  countries  and 
economies.  We  expected  to  manufacture  and  distribute  350  million  doses  of  the  prototype  vaccine  to 
countries participating in the COVAX Facility. Under a separate purchase agreement with Gavi, SIIPL was 
expected to manufacture and deliver the balance of the 1.1 billion doses of prototype vaccine to low- 
and  middle-income  countries  participating  in  the  COVAX  Facility.  We  expected  to  deliver  doses  with 
antigen and adjuvant  manufactured  at  facilities  directly  funded under  our  funding agreement  with  the 
Coalition for Epidemic Preparedness Innovations (“CEPI”), with initial doses supplied by SIIPL and Serum Life 
Sciences  Limited  (“SLS”)  under  a  supply  agreement.  We  expected  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 could prioritize such doses to low- and middle- income countries, at lower prices. 
Additionally, we could provide additional doses of prototype vaccine, to the extent available from CEPI-
funded manufacturing facilities, in the event that SIIPL could not materially deliver expected vaccine doses 
to the COVAX Facility. Under the agreement, we received an upfront payment of $350.0 million from Gavi 
in 2021 and an additional payment of $350.0 million in 2022 related to our achieving an emergency use 
license for our prototype vaccine by the WHO (the “Advance Payment Amount”). 

On November 18, 2022, we delivered written notice to Gavi to terminate the Gavi APA on the basis 
of Gavi’s failure to procure the purchase of 350 million doses of our prototype vaccine from us as required 
by  the  Gavi  APA.  As  of  November  18,  2022,  we  had  only  received  orders  under  the  Gavi  APA  for 
approximately 2 million doses. On December 2, 2022, Gavi issued a written notice purporting to terminate 
the  Gavi  APA  based  on  Gavi’s  contention  that  we  had  repudiated  the  agreement  and,  therefore, 
materially breached the Gavi APA. Gavi also contended that, based on its purported termination of the 
Gavi APA, it was entitled to a refund of the Advance Payment Amount less any amounts that have been 
credited  against  the  purchase  price  for  binding  orders  placed  by  a  buyer  participating  in  the  COVAX 
Facility. The remaining Gavi Advance Payment Amount, which was $696.4 million as of December 31, 2023 
has  been  classified  within  Other  current  liabilities  in  the  Company’s  consolidated  balance  sheet.  On 
January 24, 2023, Gavi filed a demand for arbitration with the International Court of Arbitration based on 
the claims described above. We filed our Answer and Counterclaims on March 2, 2023. On April 5, 2023, 
Gavi filed its Reply to our Counterclaims. On February 16, 2024, we and Gavi entered into a Termination 
and  Settlement  Agreement  (the  “Gavi  Settlement  Agreement”)  terminating  the  Gavi  APA,  settling  the 
arbitration  proceedings  and  releasing  both  parties  of  all  claims  arising  from,  under  or  otherwise  in 
connection with the Gavi APA. Pursuant to the Settlement Agreement, we are responsible for payment to 
Gavi of (i) an initial settlement payment of $75 million, which we paid on February 20, 2024, and (ii) deferred 
payments,  in  equal  annual  amounts  of  $80  million  payable  each  calendar  year  through  a  deferred 
payment term ending December 31, 2028. The deferred payments are due in variable quarterly installments 
beginning in the first quarter of 2024 and total $400 million during the deferred payment term. Such deferred 
payments  may  be  reduced  through  Gavi’s  use  of  an  annual  vaccine  credit  equivalent  to  the  unpaid 
balance of such deferred payments each year, which may be applied to qualifying sales of any of our 
vaccines for supply to certain low-income and lower-middle income countries. We have the right to price 
the vaccines offered to such low-income and lower-middle income countries at our discretion, and, when 
utilized by Gavi, we will credit the actual price per vaccine paid against the applicable credit. We intend 
to  price  vaccines  offered  via  the  tender  process,  consistent  with  our  shared  goal  with  Gavi  to  provide 
equitable access to those countries. Also in the Settlement Agreement, we grant Gavi an additional credit 
of  up  to  $225  million,  which  may  be  applied  against  any  additional  qualifying  sales,  exceeding  the  $80 
million  deferred  payment  amount  in  any  calendar  year,  of  our  vaccines  in  such  countries  during  such 
deferred payment term. In addition, we and Gavi entered into a security agreement pursuant to which we 
granted Gavi a security interest in accounts receivable from SIIPL under the SIIPL R21 Agreement (see Note 
4 to our consolidated financial statements for more details on SIIPL R21 Agreement), which will continue for 
the deferred payment term of the Gavi Settlement Agreement.

Product Pipeline 

(1)  Authorized in select geographies under trade names Novavax COVID-19 Vaccine, Adjuvanted; 
Covovax™; and Nuvaxovid™, and authorized in the U.S. under trade name, Novavax COVID-19 
Vaccine, Adjuvanted (2023-2024 Formula); Ongoing post-authorization Phase 3 strain change trial. 
(2)  Authorized in Ghana, Nigeria, and Burkina Faso; Commercialized by Serum Institute of India; Granted 

prequalification by the WHO. 

Pipeline Overview 

Our clinical pipeline encompasses vaccine candidates for infectious diseases, with our COVID-19 
prototype  vaccine  (NVX-CoV2373)  and  our  COVID-19  updated  vaccine  (NVX-CoV2601),  as  our  lead 
products. Our prototype and updated vaccine has received authorizations for both adult and adolescent 
populations globally. Our updated vaccine has received authorization from the U.S. FDA, the EC, the WHO, 
and several other countries globally. We advanced our updated vaccine to a post-authorization Phase 3 
safety and immunogenicity trial. Beyond our COVID-19 vaccine, our clinical pipeline includes a CIC vaccine 
candidate, in addition to our Matrix-M™ adjuvant being used for collaboration in R21/Matrix-M™ adjuvant 
malaria vaccine. 

We  are  developing  a  CIC  vaccine  candidate,  which  combines  our  COVID-19  vaccine  and  our 
updated  seasonal  nanoparticle  influenza  vaccine  candidate  in  a  single  formulation.  We  continue  to 
progress  a  Phase  2  trial  of  our  CIC  vaccine  candidate.  We  have  selected  the  CIC  dose  formulation  for 
advanced development, and contingent upon U.S. FDA concurrence, we are prepared to move directly 
into a Phase 3 trial in the second half of 2024 to support accelerated approval, with a potential launch in 
the U.S. in the fall of 2026. 

In addition to our CIC vaccine candidate, we believe our partner-led R21/Matrix™ adjuvant malaria 
vaccine presents significant potential. Based on preliminary results from an ongoing Phase 3 trial in infants 
and  toddlers  in  Africa,  showing  72-79%  efficacy,  the  R21/Matrix™  adjuvant  malaria  vaccine  has  been 
authorized in Ghana, Nigeria, and Burkina Faso, and in December 2023, was granted prequalification by 
the WHO. 

Coronavirus Vaccine Clinical Development 

We remain focused on expanding our COVID-19 vaccine label within the booster, adolescent, and 
pediatric indications. We continue to evaluate vaccine safety, immunogenicity, and effectiveness through 
ongoing clinical trials and collaborative evidence-generating real-world studies. We expect to leverage 
these clinical insights to advance additional regulatory approvals of our COVID-19 vaccine globally, amidst 
the evolving COVID-19 landscape. 

Phase 3 Strain-Change and Re-vaccination Studies 

Study  311  Part  2:  In  August  2023,  we  announced  topline  results  demonstrating  immunologic 
superiority of our bivalent prototype and Omicron BA.5 vaccine compared to our prototype vaccine (NVX-
CoV2373) for Omicron BA.5 specific responses. This study is ongoing with the last patient visit expected to 
occur in the first quarter of 2024. This study design was developed in consultation with regulatory agencies 

16

 
 
 
 
 
 
 
 
 
 
 
 
 
to support our U.S. BLA and regulatory filings in other territories for our strain-change request for our updated 
vaccine (NVX-CoV2601), and to demonstrate that our protein-based vaccine can be successfully adapted 
to new variant strains. 

Study 313: In September 2023, we fully enrolled 332 adults aged 18 and older in Part 1 of the study to 
evaluate  the  immunogenicity  and  safety  of  our  updated  vaccine  (NVX-CoV2601)  in  previously  mRNA 
vaccinated individuals. Preliminary topline results indicate that the study achieved its co-primary endpoints 
and  successfully  demonstrated  immunological  superiority  of  NVX-CoV2601  compared  to  our  prototype 
vaccine for  Omicron  XBB.1.5  specific  immune  responses.  In  November  2023,  we  fully  enrolled  338 adults 
aged 18 and older in Part 2 of the study which will evaluate the immunogenicity of our updated vaccine 
(NVX-CoV2601) in previously unvaccinated individuals. Part 2 topline results are expected in the second 
quarter  of  2024.  Data  from  Study  313  are  intended  to  support  BLA  supplements  and  similar  regulatory 
submissions in other territories for future variant strain formulations. 

Study  314:  In  September  2023,  we  fully  enrolled  401  adolescents  aged  12  to  17  years  who  were 
previously vaccinated with mRNA vaccines to evaluate the immunogenicity of boosting with our updated 
vaccine  (NVX-CoV2601)  and  with  a  bivalent  format  vaccine  containing  our  updated  vaccine  (NVX-
CoV2373  +  NVX-CoV2601).  These  data  are  intended  to  support  adolescent  heterologous  booster  label 
expansion in some territories with topline results expected in the second quarter of 2024. 

Phase 2b/3 Pediatric Hummingbird™ Study 

In August 2023, we announced topline results from our Phase 2b/3 Hummingbird™ trial that met its 
primary endpoints in children aged 6 through 11 years demonstrating both tolerability and immunologic 
responses. We remain on track to submit data for this cohort to the U.S. FDA in the first half of 2024. This 
ongoing  trial  is  evaluating  the  safety,  effectiveness  (immunogenicity),  and  efficacy  of  two  doses  of  our 
prototype vaccine (NVX-CoV2373), followed by a booster 6 months after the primary vaccination series. 
The trial includes three age de-escalation cohorts of 1,200 children each. The next cohort aged 2 through 
5 years is fully enrolled, with topline results expected in the first quarter of 2024. The last cohort aged 6 to 23 
months is fully enrolled and topline results are expected in the second quarter of 2024. 

COVID-19 Vaccine Funding 

We obtained critical funding from the U.S. government to support the development of COVID-19 
Vaccine for the U.S. population, including $1.8 billion from a partnership formerly known as Operation Warp 
Speed.  In  July  2020,  we  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 the partnership. The partnership was 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,  therapeutics,  and 
diagnostics. The Project Agreement relates to the Base Agreement we entered into with ATI in June 2020 
(the  “Base  Agreement,”  together  with  the  Project  Agreement,  the  “USG  Agreement”).  The  original  USG 
Agreement  required  us  to  conduct  certain  clinical,  regulatory,  and  other  activities,  including  a  pivotal 
Phase 3 clinical trial to determine the safety and efficacy of prototype vaccine, and to manufacture and 
deliver  to  the  U.S.  government  100  million  doses  of  the  vaccine  candidate.  Funding  under  the  USG 
Agreement is payable to us for various development, clinical trial, manufacturing, regulatory, and other 
activities.  The  USG  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 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 was terminated prior to completion, we were 
entitled to be paid for work performed and costs or obligations incurred prior to termination and consistent 
with the terms of the USG Agreement. As of December 31, 2023, we have recognized the full $1.8 billion-
funding under the USG Agreement in grant revenue.  

Our  funding  agreement  with  CEPI,  under  which  CEPI  agreed  to  fund  up  to  $399.5  million  to  us  to 

17

 
 
 
 
 
 
 
 
 
support the development of prototype vaccine, provided up to $257.0 million in CEPI Grant Funding and 
up to $142.5 million in CEPI Forgivable Loan Funding, which are loans in the form of one or more forgivable 
no-interest term loans to fund certain manufacturing activities and are not subject to restrictive or financial 
covenants.  Payments  received  under  the  CEPI  Forgivable  Loan  Funding  are  only  repayable  if  project 
vaccine,  as  defined  under  the  CEPI  funding  agreement,  manufactured  by  the  contract  manufacturing 
organization (“CMO”) network funded by CEPI is sold to one or more third parties (which could include sales 
credited under the Gavi Settlement Agreement), and such sales cover our costs of manufacturing such 
vaccine,  not  including  manufacturing  costs  funded  by  CEPI.  The  timing  and  amount  of  any  loan 
repayments is currently uncertain.

Phase 2 Clinical Trial of COVID-19-Influenza Combination Vaccine 

In November 2023, we shared that we previously evaluated 11 discrete CIC formulations in our Phase 
2 dose-confirming trial, in which we then selected the CIC dose formulation and remain on track to initiate 
the Phase 3 trial. We also observed a favorable reactogenicity profile with our combination vaccine that 
was 45 

istinguishable from the licensed influenza vaccine comparators. This preliminary data suggests that 
our  technology  can  increase  the  antigen  load  while  maintaining  acceptable  tolerability.  Pending 
regulatory concurrence from the U.S. FDA, we expect to initiate a pivotal Phase 3 trial for our CIC vaccine 
candidate in the second half of 2024, with potential accelerated approval and launch in the fall of 2026. 

In  May  2023,  we  announced  preliminary topline  data  from  our  Phase  2  trial  for  CIC,  stand-alone 
influenza, and high-dose COVID-19 vaccine candidates. All three vaccine candidates contain our Matrix-
M™ adjuvant, showed preliminary robust immune responses, reassuring safety profiles, and reactogenicity 
that was comparable to the licensed influenza vaccine comparator arms. The Phase 2 dose-confirming 
randomized, observer-blinded trial evaluated the safety and effectiveness (immunogenicity) of different 
formulations  of  the  CIC  and  influenza  vaccine  candidates,  and  higher  doses  of  Novavax's  COVID-19 
vaccine in 1,575 adults aged 50 through 80 years. The CIC vaccine candidate achieved both anti-SARS-
CoV-2 immunoglobulin G (IgG) and neutralizing levels comparable to our prototype vaccine. In addition, 
several  of  the  combination  formulations  achieved  responses  to  both  SARS-CoV-2  and  to  the  four 
homologous  influenza  strains  that  were  comparable  to  the  reference  comparators,  supporting  their 
prioritization for advanced development.  

High-dose COVID-19 Vaccine Study 

Study 205: In October 2023, we completed enrollment in a Phase 2 trial to evaluate our high-dose 
COVID-19  vaccine  for  annual  vaccination  in  994  adults  ages  50  years  and  older.  The  trial  will  compare 
immunogenicity levels of 5 micrograms of our prototype vaccine (NVX-CoV2373) against 5 micrograms, 35 
micrograms, and 50 micrograms of our updated vaccine (NVX-CoV2601) that are matched with different 
levels of adjuvant. Data from this trial is intended to potentially support further development of a higher-
dose formulation for older adults, similar to that of influenza vaccines. Topline results are expected in the 
first quarter of 2024.

Malaria 

Malaria is a life-threatening disease caused by a parasite that infects mosquitos and is subsequently 
transmitted to humans. According to the 2023 WHO World Malaria Report, in 2022, there were an estimated 
249  million  malaria  cases  and  608,000  malaria-related  deaths  worldwide.  We  believe  malaria  has  the 
potential to be preventable through our partner-led R21/Matrix-M™ adjuvant malaria vaccine, which in 
2023 received authorization in several countries and prequalification by the WHO. 

R21/Matrix-M™ Adjuvant Malaria Vaccine 

R21/Matrix-M™ adjuvant malaria vaccine, formulated with our Matrix-M™ adjuvant is developed 
by our partner, the Jenner Institute, University of Oxford, and manufactured by SIIPL. We have an agreement 
with  SIIPL  related  to  its  manufacture  of  R21/Matrix-M™  adjuvant  malaria  vaccine  under  which  SIIPL 
purchases our Matrix-M™ adjuvant for use in development activities at cost and for commercial purposes 
at a tiered commercial supply price, and pays a royalty in the single- to low-double digit range based on 
vaccine sales for a period of 15 years after the first commercial sale of the vaccine in each country. 

Phase 3 Clinical Trial of R21/Matrix-M™ Adjuvant Malaria Vaccine 

R21/Matrix-M™ adjuvant malaria vaccine is being evaluated in an ongoing Phase 3 trial conducted 
by our partner, the Jenner Institute, University of Oxford. In February 2024, peer-reviewed results from the 
Phase 3 efficacy trial were published in The Lancet reporting R21/Matrix-M™ adjuvant malaria vaccine has 
a well-tolerated safety profile and offers high-level efficacy against clinical malaria in African children at 
sites  of  both  seasonal  and  perennial  transmission.  This  Phase  3  trial  enrolled  4,800  children  aged  5  to  36 
months across five sites in four African countries with differing malaria transmission intensities and seasonality. 
The trial demonstrated efficacy of 75% when administered prior to the high transmission season during the 
12 months following a three-dose series and efficacy of 68% when administered in an age-based schedule 
in  regions  where  malaria  is  present  perennially  during  the  12  months  following  the  first  three  doses.  This 
R21/Matrix-M™ adjuvant malaria vaccine is a low-cost vaccine and has the potential to make a substantial 
contribution to reducing the burden of malaria disease and deaths in sub-Saharan Africa. 

R21/Matrix-M™ Adjuvant Malaria Vaccine Regulatory and Licensure 

In  December  2023,  the  WHO  announced  it  prequalified  the  R21/Matrix-M™  adjuvant  malaria 
vaccine to  prevent  malaria  disease  in  children  caused by  the P.  falciparum  parasite  in  endemic areas. 
Prequalification status enables United Nations agencies to procure the vaccine for eligible countries and 
will enable rollout of the vaccine in mid-2024. The WHO recommended that the R21/Matrix-M™ adjuvant 
malaria vaccine be administered in a four-dose schedule beginning at five months of age. 

In July 2023, R21/Matrix-M™ adjuvant malaria vaccine received authorization in Burkina Faso and in 

April 2023, received authorizations in Ghana and Nigeria.

License and Collaboration 

Our  commitment  to  partnering  globally  in  efforts  to  further  develop  our  COVID-19  Vaccine  is 
demonstrated through our partnership with SIIPL to supply COVID-19 vaccines to India and low- and middle-
income countries.

A summary of our license and collaboration agreements follows: 

SIIPL 

We  previously  granted  SIIPL  exclusive  and  non-exclusive  licenses  for  the  development,  co-
formulation,  filling  and  finishing,  registration,  and  commercialization  of  our  prototype  vaccine,  our 
proprietary  COVID-19  variant  antigen  candidate(s),  and  our  CIC  vaccine  candidate.  SIIPL  agreed  to 
purchase  our  Matrix-M™  adjuvant,  and  we  granted  SIIPL  a  non-exclusive  license  to  manufacture  the 
antigen drug substance component of our COVID-19 Vaccine in SIIPL’s licensed territory solely for use in the 
manufacture  of  COVID-19  Vaccine.  Novavax  and  SIIPL  equally  split  the  revenue  from  SIIPL’s  sale  of 
COVID-19 Vaccine in its licensed territory, net of agreed costs. We also have a supply agreement with SIIPL 
and  SLS  under  which  SIIPL  and  SLS  supply  us  with  prototype  vaccine,  our  proprietary  COVID-19  variant 
antigen candidate(s), and our CIC vaccine candidate for commercialization and sale in certain territories, 
as well as a contract development manufacture agreement with SLS, under which SLS manufactures and 
supplies finished vaccine product to us using antigen drug substance and Matrix-M™ adjuvant supplied by 
us. In March 2020, we entered into an agreement with SIIPL that granted SIIPL a non-exclusive license for 
the use of Matrix-M™ adjuvant supplied by us to develop, manufacture, and commercialize R21/Matrix-
M™ adjuvant, a malaria vaccine created by the Jenner Institute, University of Oxford (“R21/Matrix-M™”). 
R21/Matrix-M™ adjuvant vaccine has been licensed to SIIPL for commercialization and in December 2023 
received prequalification by the WHO. Under the agreement, SIIPL purchases our Matrix-M™ adjuvant for 
use in development activities at cost and for commercial purposes at a tiered commercial supply price, 
and pays a royalty in the single-to low- double-digit range based on vaccine sales for a period of 15 years 
after the first commercial sale of the vaccine in each country.  

Takeda 

We have a collaboration and license agreement with Takeda Pharmaceutical Company Limited 
(“Takeda”)  under  which  we  granted  Takeda  an  exclusive  license  to  develop,  manufacture,  and 
commercialize  the  Company’s  COVID-19  Vaccine  in  Japan.  Under  the  agreement,  Takeda  purchases 
Matrix-M™ adjuvant from us to manufacture doses of COVID-19 Vaccine, and we are entitled to receive 
milestone  and  sales-based  royalty  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  COVID-19 
Vaccine. In September 2021, 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  its  prototype  vaccine.  In 
February 2023, MHLW canceled the remainder of doses under its agreement with Takeda. As a result, it is 
uncertain whether we will receive future sales-based royalty payments from Takeda under the terms and 

20

 
 
 
 
 
 
 
 
 
 
conditions of their current collaboration and licensing agreement. 

SK bioscience 

We  have  a  collaboration  and  license  agreement  with  SK  bioscience  to  manufacture  and 
commercialize our prototype vaccine for sale to the governments of South Korea, Thailand, and Vietnam. 
SK bioscience pays a royalty in the low to middle double-digit range.  

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 CIC vaccine, directly and by leveraging our strategic global partnerships. In 2021 and 2020, we 
established  a  global  supply  chain  and  worldwide  partnerships  to  support  the  commercialization  of  our 
prototype vaccine. In 2023 and 2022, we modified and continued to assess our manufacturing needs and 
our global manufacturing footprint consistent with our contractual obligations to supply, and anticipated 
demand for COVID-19 Vaccine. 

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.  We  also  have  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 COVID-19 Vaccine 

We manufacture the antigen component of our COVID-19 Vaccine at our Novavax CZ facility in 

the Czech Republic.  

We  have  a  supply  agreement  with  SIIPL  and  SLS,  an  affiliate  of  SIIPL,  for  the  manufacture  of  the 
antigen component of COVID-19 Vaccine and the co-formulation, fill, and finishing of the finished vaccine 
product. In May and August 2022, we expanded our license and supply arrangements with SIIPL to include 
our proprietary COVID-19 variant antigen candidate(s), and our CIC vaccine candidate, so that SIIPL can 
manufacture  and  commercialize  a  vaccine  targeting  COVID-19  variants,  including  the  Omicron 
subvariants, and CIC vaccine, and supply such vaccines to us. 

Finished COVID-19 Vaccine 

In addition to the supply agreement with SIIPL and SLS for the co-formulation, fill, and finishing of the 
finished vaccine product, we have a contract development manufacture agreement with SLS, pursuant to 
which SLS will manufacture and supply finished vaccine product to us using antigen drug substance and 
Matrix-M™  adjuvant  supplied  by  us.  Currently,  we  depend  primarily  on  this  supply  agreement  for  co-
formulation, filling and finishing (other than in Europe) and our service agreement with PCI Pharma Services 
(“PCI”) for finishing in Europe. 

Competition in COVID-19 and Combination Vaccines 

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  with  our  nanoparticle 
configuration  formulated  with  our  Matrix-M™  adjuvant  offers  many  advantages  compared  to  other 

21

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
technologies, such as enabling dose-sparing effects and refrigerator temperature storage that is well suited 
for  developing  COVID-19  and  combination  vaccines,  as  well  as  vaccines  against  a  number  of  other 
infectious diseases. 

A number of vaccine manufacturers, research institutions, and other organizations have developed 
a vaccine for SARS-CoV-2, the virus that causes COVID-19. A variety of different vaccine technologies are 
being studied, including nucleic acid (RNA/DNA), viral vectors, live attenuated or inactivated, and protein-
based vaccines. Novavax is the first protein-based COVID-19 vaccine that received EUA by the U.S. FDA 
and a CMA by EMA in the European Union. As of February 2024, Novavax is one of three manufacturers 
that  have  a  COVID-19  vaccine  that  has  received  authorization  by  the  U.S.  FDA  for  the  2023-2024 
vaccination season, with the other manufacturers being Pfizer and Moderna. As of February 2024, the U.S. 
FDA has granted Pfizer and Moderna BLA approval for their updated vaccines in individuals 12 years and 
older and EUA for their updated vaccines in individuals 6 months to 11 years, while Novavax received EUA 
by the U.S. FDA for our updated vaccine in individuals 12 years and older. Based on our COVID-19 vaccine 
and its high efficacy against both the original and variant strains and its well-tolerated profile demonstrated 
in clinical trials, including two pivotal Phase 3 trials in the UK and U.S., we believe our vaccine candidate will 
continue to play an important role in addressing this global public health crisis. 

Additionally,  we  believe  that  our  platform  is  well  suited  for  combination  vaccines,  for  example 
influenza and COVID-19. Following our Phase 2 trial results, we have selected a CIC dose formulation and 
pending regulatory concurrence are on track to initiate a pivotal Phase 3 trial in the second half of 2024, 
with  potential  accelerated  approval  and  launch  in  the  fall  of  2026.  Other  manufacturers,  including 
Moderna and Pfizer, are in Phase 3 clinical trials with COVID-19-influenza combination candidates and have 
publicly disclosed an expected launch date as early as 2025. 

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  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. 

Patent Rights; Licenses 

We have intellectual property (patents, licenses, know-how) related to our vaccines, manufacturing 
processes, and other technologies. Currently, we have or have rights to over 630 U.S. and foreign patents 
and patent applications relating to vaccines and vaccine-related technologies. 

Patents related to our Virus-Like Particle (“VLP”) program include U.S. Patent No. 7,763,450, which 

22

 
 
 
 
 
 
 
 
 
 
 
covers, in part, the use of influenza gene sequences for high-yield production of consistent influenza VLP 
vaccines  to  protect  against  current  and  future  seasonal  and  pandemic  strains  of  influenza  viruses. 
Corresponding European patent, European Patent No. 1644037 also covers this technology. U.S. Patent Nos. 
8,080,255,  8,551,756,  8,506,967  and  8,592,197  are  directed  to  methods  of  producing  VLPs  and  inducing 
substantial immunity to an influenza virus infection by administering VLPs comprising HA and NA proteins, 
and  our  M1  protein  derived  from  the  avian  influenza  strain,  A/Indonesia/5/05.  Certain  claims  also 
encompass similar methods and compositions where the M1 protein is from a different strain of influenza 
virus  than  the influenza  HA  protein  and the influenza  NA protein.  Related  patent  protection  in  Europe is 
provided by European Patent No. 2343084, which covers, in part, vaccine compositions containing VLPs 
that contain M1, HA, and NA proteins. Our VLP patent portfolio contains many other patents, including U.S. 
Patent Nos. 8,951,537, 8,992,939, 9,144,607, 9,050,290, 9,180,180, 9,381,239, 9,464,276, 9,474,799, and other 
patents in multiple ex-U.S. jurisdictions. 

In  addition  to  our  focus  on  vaccine  programs,  we  also  pursue  patent  protection  for  our  Matrix 
Adjuvant program. Issued U.S. Patent Nos. 7,838,019, 9,205,147, 9,901,634, 8,821,881, and 10,729,764 provide 
examples of patents related to our Matrix Adjuvant program. 

We  pursue  patents  related  to  our  COVID-19  vaccine  program,  including  to  NVX-CoV2373,  our 
COVID-19 vaccine candidate. Issued U.S. Patent Nos. 10,953,089, 11,253,586, 11,541,112 provide examples 
of patents related to our COVID-19 program. 

We also have four pending PCT applications directed to our COVID program (PCT/US2022/020974, 
PCT/US2022/080700,  PCT/US2022/082331  and  PCT/US2022/027465)  and  two  pending  PCT  applications 
directed to our malaria program (PCT/US2022/078665 and PCT/US2022/080334). 

We  continue  to  prepare,  file,  and  prosecute  patent  applications  to  provide  broad  and  strong 

protection of our proprietary rights related to our vaccine products and our adjuvant program. 

The  Federal  Technology  Transfer  Act  of  1986  and  related  statutory  guidance  encourages  the 
dissemination of science and technology innovation. While our expired contract with the U.S. Department 
of  Health  and  Human  Services  (“DHHS”),  Biomedical  Advanced  Research  and  Development  Authority 
provided us with the right to retain ownership in our inventions that may have arisen during performance of 
that contract, with respect to certain other collaborative research efforts with the U.S. government, certain 
developments and results that may have commercial potential are to be freely published, not treated as 
confidential,  and  we  may  be  required  to  negotiate  a  license  to  developments  and  results  in  order  to 
commercialize products. There can be no assurance that we will be able to successfully obtain any such 
license  at  a  reasonable  cost,  or  that  such  development  and  results  will  not  be  made  available  to  our 
competitors on an exclusive or non-exclusive basis. 

Trade 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. 

Human Capital 

Employees 

As of February 23, 2024, we have 1,543 full-time employees, of whom approximately 9% hold M.D. 
or  Ph.D.  degrees  and  approximately  20%  hold  other  advanced  degrees.  Of  our  total  workforce, 
approximately  68%  of  employees  are  engaged  primarily  in  research,  development,  and  manufacturing 

23

 
 
 
 
 
 
 
 
 
 
 
 
activities and approximately 32% of employees are engaged primarily in executive, business development, 
commercial, finance and accounting, legal, and administrative functions. Except for certain employees 
located  in  Europe,  who  are  covered  by  collective  agreements  with  trade  unions  pursuant  to  local  law, 
none of our employees are represented by a labor union or works council and none of our employees have 
entered into a collective bargaining agreement with us. 

To nurture, grow, and treat our employees fairly is an integral part of our culture. We are proud to 
have won a Silver Stevie Award in 2023 for Great Employer in the Pharmaceutical category. We believe this 
award reflects our investment in an exceptional work culture. 

Compensation and Benefits; Health and Wellness 

Our  total  rewards  package  is  designed  to  attract,  engage,  motivate,  and  retain  top  talent.  We 
strive to provide compensation, benefits, and services that help meet the varying needs of our employees. 
Our  generous  total  rewards  package  for  employees  in  the  U.S.  includes  competitive  market  pay  and 
comprehensive benefits, including insurance to protect and maintain health; income protection through 
our  short-  and  long-term  disability  programs  and  life  insurance;  adoption  assistance  and  paid  parental 
leave programs; and services to assist in balancing work and personal life, such as backup child, adult, and 
elder care, and financial well-being programs, including monthly financial wellness seminars, one-on-one 
financial planning sessions, and debt and credit management support. 

Our  wellness  initiatives  include  a  monthly  newsletter,  which  highlights  organizations  and partners, 
tools,  and  resources  intended  to  help  our  employees  lead  healthier  and  happier  lives.  We  offer  several 
digital apps that allow our employees to connect to an online licensed therapist or to access activities that 
are designed to reduce stress and anxiety and increase mindfulness and emotional well-being. We have a 
robust employee assistance program for employees to access support for a variety of life events. 

In  addition,  we  offer  the  majority  of  employees  the benefit  of  equity  ownership in  the Company 
through  equity  grants  or  participation  in  our  employee  stock  purchase  plan.  We  believe  that  equity 
compensation  has  been,  and  will  continue  to  be,  a  critical  component  of  our  compensation  package 
because it develops a culture of ownership among our employees and aligns their interests with the interests 
of our stockholders. 

Recruitment, Development, and Training 

The  attraction,  development,  and  retention  of  employees  is  a  critical  factor  for  our  success.  We 
utilize  a  variety  of  recruitment  vehicles  to  source  top  talent,  including  strategic  partnerships  with  search 
firms, leveraging social media channels, and a robust employee referral program. In 2023, we launched 
the Leading@Novavax competency model to define great leadership. At Novavax, everyone is a leader 
and this model and associated tools, resources, and programs develops leadership skills at all levels of the 
organization. 

To  support  the  growth  and  advancement  of  our  employees,  we  offer  tuition  and  continuing 
education reimbursement, and an array of training and professional development opportunities, including 
on-the-spot coaching with executive coaches and access to the LinkedIn Learning library of over 16,000 
on-demand video  tutorials  that  address  skills,  knowledge,  and  behaviors  related  to  business,  leadership, 
technology, and innovation. In the last 12 months, videos were viewed and completed over 40,000 times 
by  our  employees.  In  addition,  approximately  135  employees  have  participated  in  spot  coaching.  We 
provide  an  Executive  Development  Program  for  employees  identified  as  having  high  potential  and  for 
employees  who  have  been  identified  as  potential  successors  to  leadership  positions  through  our  talent 
review  and  succession  planning  process.  Our  Executive  Development  Program  includes  executive 
coaching  engagements  and  leadership  development  programs  designed  to  strengthen  our  leadership 
bench and accelerate and prepare our top talent for future growth. The Executive Development Program 
includes  a  diverse  and  global  group  of  34  employees.  Professional  development  learning  series  are 
available  to  all  employees  and  focus  on  self-awareness,  collaboration,  hybrid  working,  leadership,  and 
business acumen. 

24

 
 
 
 
 
 
 
 
 
 
 
Internal Communications 

We employ a variety of tools to facilitate open and direct communication, including global forums 
with  executives,  employee  surveys,  and  engagement  through  forums  and  committees.  Our  executive 
leadership team recognizes the importance of increased employee engagement to the success of each 
individual’s career and to our success as a whole. 

Diversity, Equity and Inclusion 

Our culture of diversity, equity and inclusion (“DEI”) helps us to create, develop and leverage the 
strengths of our workforce to meet our growth objectives. Our multi-year DEI roadmap includes three pillars:  

• 
• 

• 

Embed DEI into our hiring decisions and processes. 

Enable our employees, who we refer to as our SuperNovas, to live our values and thrive in a culture 
of inclusion. 

Equip  our  leaders  and  SuperNovas  with  the  understanding,  capability,  education,  tools  and 
resources on DEI. 

We  acknowledge  global  DEI-related  observances  and  we  invest  in  training  to  build  an  inclusive 
culture  and  develop  our  leaders  to  access  different  perspectives  when  generating  ideas  and  decision 
making.  In  2023,  we  also  made  progress  in  increasing  representation  for  women  and  minorities  at  the 
Executive level. We commenced and completed the reviews of three people processes, namely, Talent 
Acquisition,  Promotion  and  Performance  Management.  We  also  have  intentionally  incorporated  DEI 
principles  into  our  Novavax Leadership  Model.  We  believe our  multi-year  DEI  strategy  and roadmap  will 
enable us to continuously improve and excel. 

Empowering our Employees 

In 2023, Novavax sought to motivate and empower employees through a variety of programs: 

•  Made charitable donations in employees’ name to other mission-driven organizations in the U.S., 

Sweden and Czech Republic through employee match and direct giving. 

• 

Furthered  personal  and  professional  development  by  providing 
tuition  and  education 
reimbursement  and  providing  access  to  professional  coaching  and  Executive  Development 
programming for high-potential employees. 

Environmental, Social, and Governance 

In addition to the DEI and human capital initiatives described above, a range of other initiatives 
related  to  environmental,  social  and  governance  (“ESG”)  are  underway.  These  include  environmental 
sustainability, innovating for vaccine access and improving global health, empowering our employees and 
governing responsibly. We believe that our multi-stakeholder approach through these focus areas is critical 
to  our  long-term  success  and  enhances  value  for  our  shareholders.  Examples  of  initiatives  supportive  of 
these focus areas include the following: 

Environmental Sustainability 

•  Resource management and greenhouse gas reduction strategy, which includes tracking emissions. 
•  An approach to Procurement that incorporates sustainability metrics into vendor evaluation and 

selection rubrics. 

• 

Lease  of  approximately  170,000  square  foot  property  in  Gaithersburg,  Maryland  at  700  Quince 
Orchard Road, certified LEED Silver and designed with energy efficiency and sustainability measures 
in place. 

•  Conserving  water  (e.g.,  by  replacing  single-serve  water  bottles  with  refillable  options)  and 

monitoring energy use across multi-use leased and owned facilities. 

•  Award of WELL certifications at multiple leased facilities.

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.  We  focus  on the U.S. 
regulatory process and the standards imposed by the U.S. FDA, the International Council for Harmonisation 
(“ICH”), and other agencies because we believe meeting U.S. and ICH standards generally allows us to 
also satisfy regulatory agencies’ standards in other countries where we intend to do business. However, we 
are mindful 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 take proactive steps to address such 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  U.S.  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 U.S. 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 U.S. FDA licensure to market any new vaccine candidate, 
we  expect  to  first  submit  an  investigational  new  drug  application  (“IND”)  that  explains  to  the  U.S.  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 our 
proposed plans for human testing. At this stage, the U.S. 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 U.S. FDA. Following successful completion of all three phases 
of clinical development, a BLA can be submitted to the U.S. 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 U.S. FDA will only approve a BLA if the vaccine is demonstrated to be safe, pure, and potent. 
During  the  U.S.  FDA’s  review  of  a  BLA,  the  proposed  manufacturing  facility  undergoes  a  pre-approval 
inspection during which the U.S. 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 U.S. 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 U.S. FDA may, following the issuance of an appropriate declaration by the 
Secretary  of  the  DHHS,  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 U.S. 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 declaration issued by the Secretary of the DHHS that EUAs are appropriate. 
The U.S. 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 U.S. FDA determines that the underlying public health threat 
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 

27

 
 
 
 
 
 
emerging data that may demonstrate the product may not be effective. An EUA is separate from and not 
dependent on the issuance of a public health emergency (“PHE”) by the Secretary of the DHHS. Therefore, 
although the COVID-19 PHE expired on May 11, 2023, that expiration will not terminate EUAs issued by the 
U.S. FDA. 

In order to ensure continuing safety, the U.S. FDA and 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 the results of their own tests for potency, safety, and purity for each vaccine lot, 
if  requested  by  the  relevant  regulatory  agency.  They  may  also  be  required  to  submit  samples  of  each 
vaccine lot to the agency for testing. 

In  addition  to  obtaining  U.S.  FDA  licensure  for  each  product,  each  domestic  manufacturing 
establishment must be registered with the U.S. FDA, is subject to U.S. FDA inspection, and must comply with 
current 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 U.S. FDA or by 
corresponding regulatory agencies in their home country. 

The EU and the UK similarly provide a faster means to achieve approval by offering CMA to fulfil 
unmet medical needs. CMAs are granted with the proviso of obtaining additional comprehensive data to 
confirm the benefit/risk so that the MA will eventually become unconditional. The benefit to public health 
of the immediate availability on the market of the medicinal product concerned should outweigh the risk 
inherent in the fact that additional data are still required. 

The U.S. FDA has several programs designed to expedite the development and approval of drugs 
and biological products intended to treat serious or life-threatening diseases or conditions, including fast 
track  designation,  breakthrough  therapy  designation,  priority  review  designation,  and  accelerated 
approval. First, the U.S. 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 U.S. FDA and the 
U.S.  FDA  may  initiate  review  of  sections  of  a  Fast  Track  product’s  application  before  the  application  is 
complete. The U.S. FDA granted Fast Track Designation for our prototype vaccine in November 2020 and 
for 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 therapies on one or more clinically significant endpoints. The U.S. 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 U.S. 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 U.S. 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 

28

 
 
 
 
 
 
 
 
 
condition and generally provides a meaningful advantage over available therapies. In addition, it must 
demonstrate an effect on a surrogate endpoint that is reasonably likely to predict clinical benefit or on a 
clinical  endpoint  that  can  be  measured  earlier  than  irreversible  morbidity  or  mortality  (“IMM”)  that  is 
reasonably likely to predict an effect on IMM or other clinical benefit. As a condition of approval, the U.S. 
FDA may require that a sponsor 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 U.S. FDA acknowledged that the accelerated approval pathway is available for our 
recombinant quadrivalent seasonal influenza vaccine candidate. 

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.  U.S.FDA  licensure  does  not  guarantee  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 facilities in Sweden, the Czech Republic and Switzerland. 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.  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 
payers.  Third-party  payers  include  government  authorities  or  programs,  private  health  insurers  (including 
managed care plans), and other organizations. These third-party payers 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 
U.S.  FDA  or  similar  regulatory  authorities  outside  the  United  States.  Our  product  candidates  may  not  be 
considered 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,  including  initiatives  to  reduce  the  cost  of  healthcare.  In  March 

29

 
 
 
 
 
 
 
2010, the U.S. Congress enacted the Patient Protection and Affordable Care Act and the Health Care and 
Education  Reconciliation  Act  (“ACA”),  which  includes  changes  to  the  coverage  and  reimbursement  of 
drug  products  under  government  health  care  programs.  Since  its  enactment,  there  have  been  several 
executive, judicial and Congressional challenges to certain aspects of the ACA, and additional challenges 
and amendments to the ACA may reduce the profitability of drug products. 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 proposed and adopted in the United States since the ACA 
was enacted that impact drug pricing. 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. Under the American Rescue Plan 
Act of 2021 (“ARPA”), Medicaid and Children’s Health Insurance Program (“CHIP”) programs must cover 
without cost-sharing COVID-19 vaccines for most Medicaid and CHIP enrollees through September 30, 2024. 
After such date, under the Inflation Reduction Act of 2022 (“IRA”), Medicaid and CHIP programs will be 
required  to  cover  without  cost-sharing  only  U.S.  FDA-approved  COVID-19  vaccines  for  adults  as 
recommended by the ACIP. 

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. 

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. 

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 payers (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 

30

 
 
 
 
 
 
 
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. The IRA will delay implementation of this Rebate Rule until 2032. 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 
developments may impact our business and operations if our products are commercialized in the U.S. 

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 
UK 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 of, 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 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 

31

 
 
 
 
 
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 also are U.S. federal transparency requirements under the Physician Payments Sunshine Act 
that require manufacturers of U.S. FDA-approved drugs, devices, biologics and medical supplies covered 
by Medicare or Medicaid to report, on an annual basis, to CMS information related to payments and other 
transfers  of  value  to  physicians,  teaching  hospitals,  and  certain  advanced  non-physician  health  care 
practitioners and physician ownership and investment interests. Some U.S. states have transparency laws 
requiring the reporting of information that differs from the scope of information reported under the federal 
law, which permits these additional state requirements. 

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. 

Given  the  significant  global  impact  of  the  COVID-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 our COVID-19 Vaccine 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  will  create 
challenges and potential delays in our development and production activities and may necessitate that 
we pursue strategies to develop and produce our vaccine candidates within 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  commercialization  of  our  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 
Readiness  and  Emergency  Preparedness  Act  (the  “PREP  Act”),  when  applicable,  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 

32

 
 
 
 
 
 
 
some  circumstances.  “Covered  countermeasures” 

the  manufacturer  under 
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 invoke the PREP Act by issuing a declaration that a public health emergency or “credible risk” 
of a future public health emergency exists. 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.  The  current 
declaration will end on December 31, 2024, unless it is renewed. While we believe our products would be 
covered under the current PREP Act declaration, this cannot be assured. 

include 

Also, there can be no assurance that the Secretary of the DHHS 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.

Item 1A.  RISK FACTORS 

You should carefully consider the following risk factors in evaluating our business. A number of risks 
could  cause  our  actual  results  to  differ  materially  from  those  that  are  indicated  by  forward-looking 
statements. Some risks relate principally to our business and the industry in which we operate. Others relate 
principally  to  the  securities  market  and  ownership  of  our  common  stock.  The  risks  and  uncertainties 
described below are not the only ones we face. Additional risks and uncertainties of which we are unaware, 
or  that  we  currently  deem  immaterial,  also  may  become  important  factors  that  affect  us.  Any  of  the 
following  risks  could  result  in  material  adverse  impacts  on  our  business,  financial  condition,  or  results  of 
operations. You also should consider the other information included in this Annual Report on Form 10-K as 
well as our other filings with the SEC.

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 remains uncertain. While we have 
received full MA, provisional registration, CMA, or EUA for our prototype COVID-19 Vaccine and our 
updated COVID-19 vaccine in a number of jurisdictions, we may be unable to obtain full regulatory 
approvals in the U.S. or other jurisdictions for our updated vaccine or new versions in the future or 
produce a successful vaccine in a timely manner, if at all. 

The  emergence  and  transmissibility  of  variants  of  the  SARS-CoV-2  virus,  may  affect  market 
acceptance or sales of our COVID-19 Vaccine, and our strategy to develop new versions of our 
COVID-19 Vaccine to protect against certain variants may not be successful. 

•  We  are  a  biotechnology  company  and  face  significant  risk  in  developing,  manufacturing,  and 

commercializing our products and product candidates. 

• 

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 the commercial success of our COVID-19 Vaccine, and even though 
we  have  received  provisional  registration,  CMA,  EUA  or  full  marketing  authorization  in  certain 
jurisdictions for our COVID-19 Vaccine, and even if we have products licensed in additional markets, 
our vaccine products may not be initially or ever profitable. 

• 

The  risks  associated  with  COVID-19  and  related  governmental  public  health  policies  continue  to 
evolve,  which  may  have  unpredictable  effects  on  the  prospects  for  commercial  success  of  our 
COVID-19 Vaccine. 

•  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 and a combined 
vaccine against COVID-19 and influenza, and we may never see returns on the significant resources 
we are devoting to our vaccine candidates. 

•  We may not succeed in obtaining full U.S. FDA licensure or foreign regulatory approvals necessary 

to sell our vaccine candidates. 

•  Our product candidates might fail to meet their primary endpoints in clinical trials, meaning that we 

• 

will not have the clinical data required to support full regulatory approvals. 
The regulatory pathway for our COVID-19 Vaccine is continually evolving, and such evolution 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 our COVID-19 Vaccine at sites outside the U.S. and the U.S. 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. 

•  Given our current cash position and cash flow forecast, and significant uncertainties related to 2024 
revenue, substantial doubt exists regarding our ability to continue as a going concern through one 

34

 
 
 
 
year from the date that the financial statements included in this Annual Report were issued. 

• 

• 

• 

Servicing our 5.00% convertible senior unsecured notes due 2027 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,  2023  was  $4.8  billion.  Our  revenue  and  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 foreseeable future. Our net losses for the last three fiscal years were $0.5 billion in 2023, $0.7 
billion in 2022, and $1.7 billion in 2021. 

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  other  general  and 
administrative operating 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 efforts  to  develop,  test,  manufacture,  and 
make regulatory filings for our vaccine candidates, and commercialize our COVID-19 Vaccine and any 
other product candidates that receive requisite regulatory approvals. 

As  of  the  end  of  fiscal  year  2023,  our  investment  in  the  development  and  manufacture  of  our 
COVID-19 Vaccine has been substantial, and we expect such levels of investment to continue for the rest 
of 2024 and beyond, although the precise magnitude of our total investment will depend on the duration 
of  the  impact  of  COVID-19,  the  competitive  landscape,  the  timing  and  results  of  our  applications  for 
regulatory  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 
investments. We expect to continue to incur significant operating expenses and anticipate significant losses 
over time as we seek to: 

•  conduct  additional  clinical  trials  and  continue  to  seek  regulatory  approvals  for  our  COVID-19 

Vaccine and other potential vaccine candidates; 

•  conduct preclinical studies for other potential vaccine candidates; 
•  expand  our  global  manufacturing  and  distribution  capacity,  and  further  commercialize  our 

COVID-19 Vaccine; and 

•  maintain, expand and protect our intellectual property portfolio. 

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 will continue to require significant funding to maintain our current level of operations and fund 

the further development of our vaccine candidates. 

35

 
 
 
 
 
 
 
 
 
 
 
We  do  not  currently  generate  sufficient  revenue  from  product  sales,  licensing  fees,  royalties, 
milestones, contract research or other sources to fully fund our operations. We, therefore, will use our cash 
resources, and expect to require additional funds, to maintain our operations, continue our research and 
development  programs,  advance  preclinical  studies  and  clinical  trials,  seek  regulatory  approvals  and 
manufacture and market our COVID-19 Vaccine and any other product candidates that are approved for 
commercialization. 

To date, we have financed our operations primarily through the sale of equity and debt securities, 
government  funding  and  grant  agreements,  and  supply  agreements  (also  sometimes  referred  to  as 
advance  purchase  agreements)  for  our  COVID-19  Vaccine.  Although  we  have  entered  into  supply 
agreements  for  our  COVID-19  Vaccine  that  include  prepayments  from  the  purchasers,  until  we  can 
generate  sufficient  product  revenue  from  such  agreements  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,  as  well  as  existing  cash,  potential  collaborations,  strategic  alliances  and 
marketing,  distribution  or  licensing  arrangements,  funding  from  governmental  and  non-governmental 
funding entities, and potentially 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  favorable  terms,  or  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 our COVID-19 Vaccine 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,  under  certain  supply 
agreements, if we do not timely achieve requisite regulatory milestones for our COVID-19 Vaccine in the 
relevant jurisdictions, obtain supportive recommendations from governmental advisory committees, and/or 
achieve product volume or delivery timing obligations, purchasers may seek to terminate such agreements, 
reduce their purchase commitments, require us to refund all or some prepayments we have received, or 
renegotiate  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  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 and political 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,  particularly  due  to  the  impact  of 
increased interest rates, and inflation. In addition, our operations and performance may be affected by 
political or civil unrest or military action, including the ongoing conflicts between Russia and Ukraine and 
Israel and Hamas as well as hostilities elsewhere in the Middle East. Access to capital markets is critical to 
our  ability  to  operate.  Traditionally,  biotechnology  companies  have  funded  their  research  and 
development  expenditures  by  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  development,  manufacturing,  regulatory  and  commercialization 
efforts. We require significant capital for our current and 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. The capital and credit markets 
may not be available to support future capital raising activity on favorable terms. If economic conditions 
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 contemplated would be compromised. Moreover, we rely and intend to rely 
on 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  parties  are  unable  to  adequately 

36

 
 
 
 
 
satisfy their contractual commitments to us in a timely manner, our business could be adversely affected. 

Our existing funding and supply agreements or our advance purchase agreements do not assure 
success of our vaccine candidates or vaccines or that we will be able to fully fund our vaccine candidates 
or vaccines or our company operations, and if we are unable to satisfy the performance obligations under 
such agreements the agreements may be terminated, the purchase commitments may be reduced or we 
may be required to refund advance payments. 

Our funding agreements with the U.S. government (“USG”) and CEPI each reimburse a portion of 
the expenses associated with the development and commercialization of our COVID-19 Vaccine. To the 
extent  funding  commitments  in  such  agreements  are  conditioned  on  our  meeting  certain  milestones  or 
conditions, we may not ultimately receive the full amount of committed funds and may require additional 
funding to support our COVID-19 Vaccine development and commercialization activities, and we may be 
unable to timely obtain additional funding. For example, in July 2021, in connection with funding from the 
USG partnership formerly known as Operation Warp Speed, the USG instructed us to prioritize alignment with 
the FDA on our analytic methods before conducting additional U.S. manufacturing, and the USG indicated 
that it would not fund additional U.S. manufacturing until such alignment was reached, which did not occur 
until  June  2022.  In  February  2023,  in  connection  with  the  execution  of  Modification  17  to  the  USG 
Agreement,  the  U.S.  government  indicated  to  us  that  the  award  may  not  be  extended  past  its  current 
period of performance. The USG Agreement also 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 in 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 USG. The CEPI 
funding agreement, meanwhile, provides CEPI certain “march-in” rights in the event of certain breaches of 
that agreement. Additionally, we have entered into, and plan to continue entering into, supply agreements 
(also  sometimes  referred  to  as  advance  purchase  agreements)  for  our  COVID-19  Vaccine  that  include 
prepayments from the purchasers to help fund our development and manufacture of the vaccine. Under 
certain supply agreements, if we do not timely achieve requisite  regulatory milestones for our COVID-19 
Vaccine  in  the  relevant  jurisdictions,  obtain  supportive  recommendations  from  governmental  advisory 
committees,  and/or  achieve  product  volume  or  delivery  timing  obligations,  purchasers  may  seek  to 
terminate  such  agreements,  reduce  their  purchase  commitments,  require  us  to  refund  all  or  some 
prepayments we have received, or renegotiate such agreements, each of which could have a material 
and adverse effect on our financial condition. The timing to fulfill performance obligations related to supply 
agreements  will  depend  on  timing  of  product  manufacturing,  receipt  of  marketing  authorizations  for 
additional indications, delivery of doses based on customer demand, and the ability of the customer to 
request variant vaccine in place of prototype vaccine under certain of our supply agreements. 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 
COVID-19 Vaccine. Such upfront payments generally become non-refundable upon our achievement of 
certain development, regulatory and commercial milestones. We may not achieve such milestones, which 
could  have  a  material  and  adverse  effect  on  our  financial  condition.  For  example,  in  September  2022, 
following a delay in obtaining regulatory approval in the United Kingdom, we entered into the Amended 
and Restated  UK Supply Agreement,  which  amended and restated  in  its  entirety the Original  UK Supply 
Agreement, which reduced the volume of vaccine doses that the Authority is committed to purchase as 
compared to the Original UK Supply Agreement. Under the terms of the Amended and Restated UK Supply 
Agreement,  the  Authority  agreed  to  purchase  a  minimum  of  1 million  doses  and  up  to  an  additional 
15 million doses (the “Conditional Doses”) of our prototype vaccine, with the number of Conditional Doses 
contingent  on,  and  subject 
timely  achievement  of  supportive 
recommendations from the JCVI that is approved by the UK Secretary of State for Health. If the Authority 
did  not  purchase  the  Conditional  Doses  or  the  number  of  such  Conditional  Doses  was  reduced  below 
15 million doses of our prototype vaccine, we would have to repay up to $225.0 million related to the upfront 
payment  previously  received  from  the  Authority  under  the  Original  UK  Supply  Agreement.  Under  the 
Amended  and  Restated  UK  Supply  Agreement,  the  Authority  also  has  the  option  to  purchase up  to  an 
additional 44 million doses, in one or more tranches, through 2024.

As of November 30, 2022, the JCVI had not made a supportive recommendation with respect to 
our  prototype  vaccine,  thereby  triggering,  under  the  terms  of  the  Amended  and  Restated  UK  Supply 
Agreement, (i) a reduction of the number of Conditional Doses from 15 million doses to 7.5 million doses, 
which reduced number of Conditional Doses are contingent on, and subject to further reduction based 
on,  our  timely  achievement  by  November  30,  2023  of  a  supportive  recommendation  from  JCVI  that  is 
approved  by  the  UK  Secretary  of  State  for  Health  as  described  in  the  paragraph  above,  and  (ii)  an 
obligation  for  us  to  repay  $112.5  million  related  to  the  upfront  payment  previously  received  from  the 
Authority under the Original UK Supply Agreement. In April 2023, we repaid the $112.5 million related to the 
November  30,  2022  triggering  event.  As  of  November  30,  2023,  the  JCVI  had  not  made  a  supportive 
recommendation with respect to the prototype vaccine, thereby triggering a reduction in the number of 
Conditional Doses from 7.5 million doses to zero. As of February 2024, the Company is in discussions with the 
Authority regarding the treatment of the remaining upfront amount previously received of $112.5 million, 
which is reflected in Other current liabilities on our consolidated balance sheet.  

In July 2023, we amended the Australia APA to provide for replacement doses and to extend the 
delivery  schedule  through  2025.  As  of  February  2024,  we  had  not  yet  received  TGA  authorization  or 
delivered  doses  as  contemplated  in  the  July  2023  amendment  and  are  in  active  discussions  with  the 
Australian government on both the TGA authorization and delivery of the doses previously scheduled for 
the fourth quarter of 2023. In February 2024, we received notice from the Australian government purporting 
to cancel its order for such prototype vaccine doses. We believe the cancellation was not proper under 
the amended Australia APA. However, if such a cancellation were determined to be allowable, $6.0 million 
of the deferred revenue would become a credit towards future deliveries of doses and approximately $48 
million of the contract value related to future deliverables would no longer be available. 

In April 2023, we amended the Canada APA, pursuant to which the Canadian government forfeited 
certain doses originally scheduled for delivery in 2022 for a payment of $100.4 million, which we received in 
the  second  quarter  of  2023.  In  June  2023,  we  entered  into  an  additional  amendment  (the  “June  2023 
Amendment”) to the Canada APA. Pursuant to the June 2023 Amendment, (i) the Canadian government 
forfeited certain doses of COVID-19 Vaccine previously scheduled for delivery and agreed to pay a total 
amount of $349.6 million to us in two equal installments, which total amount equaled the remaining balance 
owed by the Canadian government with respect to such forfeited vaccine doses, (ii) the amount of doses 
of COVID-19 Vaccine due for delivery was reduced, (iii) the delivery schedule for the remaining doses of 
COVID-19  Vaccine  to  be  delivered  was  revised,  and  (iv)  the  parties  agreed  Novavax  would  use  the 
Biologics Manufacturing Centre (“BMC”) Inc. to produce bulk antigen for doses in 2024 and 2025. The June 
2023 Amendment maintained the total contract value of the original Canada APA. The first installment of 
$174.8 million was payable upon execution of the June 2023 Amendment and received by Novavax in July 
2023,  and  the  second  installment  of  $174.8  million  was  contingent  and  payable  upon  the  delivery  of 
vaccine  doses  in  the  second  half  of  2023  and  received  by  Novavax  in  January  2024.  The  Canadian 
government may terminate the Canada APA, as amended, if we fail to receive regulatory approval for our 
COVID-19 Vaccine using bulk antigen produced at BMC on or before December 31, 2024. Our 2024 plans 
do  not  currently  anticipate  the  submission  for  regulatory  approval  of  our  COVID-19  Vaccine  using  bulk 
antigen produced at BMC, and we plan to work with the Canadian government on an amendment that 
addresses possible alternatives, which may not be achievable. As of December 31, 2023, $102.8 million was 
classified as short-term Deferred revenue and $485.3 million was classified as long-term Deferred revenue 
with  respect  to  the  Canadian  APA  on  our  consolidated  balance  sheet.  If  the  Canadian  government 
terminates  the  Canada  APA,  $28.0  million  of  the  deferred  revenue  would  become  refundable  and 
approximately $224 million of the contract value related to future deliverables would no longer be available 
(see  Note  3  to  our  consolidated  financial  statements).  As  a  result,  our  existing  funding  and  supply 
agreements or our advance purchase agreements do not assure success of our vaccine candidates and 
may be insufficient to fully fund the development and commercialization of our vaccine candidates, our 
vaccines or our company operations and if we are unable to satisfy the performance obligations under 
such agreements the agreements may be terminated, the purchase commitments may be reduced or we 
may be required to refund advance payments.

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  products.  Our  development  efforts  and,  if  those  are  successful, 
commercialization  of  our  COVID-19  Vaccine  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 respect to which our COVID-19 Vaccine proves less effective; 
•  we  or  our  third-party  manufacturer  facilities  fail  to  reproducibly  scale-up  and  maintain 
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 uneconomical to market or manufacture; 

some  or  all  of  the  products  that  we  or  our  third-party  partners  have  manufactured  may  be 
determined to be unsalable based on criteria imposed by regulators as they 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 

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 remains uncertain. While we have 
received provisional registration, conditional marketing authorization or emergency use authorization for 
our COVID-19 Vaccine in a number of jurisdictions, we may be unable to obtain full regulatory approvals 
in the U.S. or other jurisdictions for our updated vaccine or new versions in the future or produce a successful 
vaccine in a timely manner, if at all. 

In  response  to  the  outbreak  of  COVID-19,  we  began  pursuing,  and  continue  to  pursue,  the 
development and manufacture of our COVID-19 Vaccine. Even though we have reported positive data 
from Phase 1, 2 and 3 clinical trials, and we and our partners have received either provisional registration, 
conditional marketing authorization, emergency use authorization, or full approval from the World Health 
Organization and in several jurisdictions, 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 our COVID-19 Vaccine has received regulatory authorizations in certain 
jurisdictions and may receive further regulatory approval in others, successful commercialization depends 
on our ability to effectively scale up and maintain 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 but we have yet to receive regulatory approval at this site. We also are 
actively entering into agreements with third parties to manufacture the antigen component of COVID-19 
Vaccine and our proprietary Matrix-M™ adjuvant, as well as to distribute our COVID-19 Vaccine. Because 
of contractual restraints and the limited number of third-party manufacturers with the relevant expertise, 
required regulatory approvals and facilities to manufacture our COVID-19 Vaccine and its components at 
commercial  scale,  replacement  of  a  manufacturer  may  be  expensive  and  time-consuming  and  may 
cause interruptions in production. Manufacturing of our COVID-19 Vaccine and its components involves a 
complicated process that will require significant investments of time and financial resources to implement, 

39

 
 
 
 
 
 
 
and  our  efforts  to  establish  and  maintain  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  or  receive  regulatory  approvals  for  our  COVID-19  Vaccine  in  adequate  quantities  to  address 
global demand. 

We have limited experience with the commercial launch of vaccine products. 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 
and maintain 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. 

The emergence and transmissibility of variants of the SARS-CoV-2 virus, and the demand for bivalent 
vaccines, may affect market acceptance or sales of our COVID-19 Vaccine, and our strategy to develop 
new versions of our COVID-19 Vaccine to protect against certain variants may not be successful. 

Our prototype vaccine was a monovalent vaccine developed based upon the genetic sequence 
of the SARS-CoV-2 virus that was first discovered in December 2019. Our updated vaccine is a monovalent 
vaccine developed based upon the XBB.1.5 strain for the fall 2023 COVID-19 Vaccine season. As the SARS-
CoV-2 virus continues to evolve, new strains of the virus, or those that are already in circulation, may prove 
more transmissible or cause more severe forms of COVID-19 disease than the predominant strains to date. 
For  example,  Alpha,  Beta,  Delta  and  Omicron  (including  subvariants  such  as  XBB.1.5  and  JN.1)  variants 
have been observed to be more transmissible, or contagious, than previous variants. 

Our COVID-19 Vaccine may not be as effective in protecting against these or other future variant 
strains.  Additionally,  we  expect  the  demand  for  bivalent  vaccines  to  continue  to  increase,  which  may 
negatively impact the demand, particularly in the U.S., for our COVID-19 Vaccine and would likely require 
significant expenditures by the Company to successfully market a bivalent formulation, particularly in the 
U.S. Our COVID-19 Vaccine may fail to achieve market acceptance or significant sales, despite gaining 
regulatory  approval,  provisional  registration,  conditional  marketing  authorization  or  emergency  use 
authorization in a number of jurisdictions, including emergency use authorization the U.S., as demand for 
variant-specific  or  bivalent  vaccines  increases.  We  have  several  variant-specific  vaccine  candidates  in 
development, including for Omicron subvariants and may develop others in the future. However, if these 
efforts are unsuccessful, these candidates do not receive regulatory approvals expeditiously, we are slower 
to  develop variant-specific  or  bivalent  vaccines  than  competitors,  these  vaccine candidates  prove  less 
effective than competitors’ vaccines, or we are unable to successfully manufacture, distribute or market 
such  vaccine  candidates  once  approved,  these  shortcomings  may  lead  to  reputational  harm,  loss  of 
market share, and adverse financial results. 

Our 2024 revenue depends on our ability to successfully develop, manufacture, distribute, or market 
an updated monovalent or bivalent formulation of a vaccine candidate for COVID-19 in a single dose vial 
or pre-filled syringe for the fall 2024 COVID vaccine season, which is inherently uncertain and subject to a 
number of risks, including regulatory approval. We experienced delays in early 2023 in manufacturing our 
BA.5 clinical trial materials, which delayed regulatory approval from the U.S. FDA for our vaccine candidate 
for the fall 2023 COVID vaccine season.  

Further,  counterparties  to  certain  of  our  existing  supply  agreements  may  request  variant-specific 
vaccines in place of our COVID-19 Vaccine and, depending on when we are able to offer such variant-
specific vaccines, if at all, such counterparties may seek to delay, reduce or otherwise renegotiate their 
purchase commitments, which may adversely impact our ability to realize the full financial benefit of such 
supply agreements. In addition, we may expend significant resources adapting our COVID-19 Vaccine or 
conducting clinical trials to protect against variants of the SARS-CoV-2 virus, but a market for this adapted 

40

 
 
 
 
 
 
 
 
vaccine may not develop and demand may not align with our projections or cost expenditures. 

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, our COVID-19 Vaccine 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 U.S. 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. 
limit  the  successful 
in  the  vaccine 
commercialization of any products for which we receive commercial approval.

We will require approval from the U.S. FDA of any name we intend to use for our products regardless 
of whether we have secured a trademark registration from the USPTO. The U.S. FDA typically conducts a 
review of proposed product names, including an evaluation of potential for confusion with other product 
names. The U.S. FDA may object to any product name we submit if it believes the name inappropriately 
implies medical claims. If the U.S. 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 
U.S. FDA. We may be unable to build a 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.  In 
particular,  we  currently  depend  significantly  on  SIIPL  and  SLS  for  co-formulation,  filling,  and  finishing  our 
COVID-19 Vaccine (except in Europe, where we rely on PCI Pharma Services (“PCI”)). If SLS or PCI is unable 
to provide sufficient co-formulation, fill, and finish services to us, fails to meet regulatory requirements, or 
otherwise defaults on its obligations to us, we may not be able to obtain alternative co-formulation, fill, and 
finish services from other providers on acceptable terms in a timely manner or at all, which could prevent 
or delay delivery of customer orders, or otherwise negatively affect our business. Certain of our facilities are 
also contracted for defined time frames and through association with USG and CEPI, and we may not be 

41

 
 
 
 
 
 
 
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  U.S.  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  U.S.  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 and unusable 
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. 

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 and NVX-CoV2601 trials, and for commercialization 
of  our  updated  vaccine.  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  our  COVID-19  Vaccine  in  response  to  the  outbreak  of 
COVID-19,  a  global  pandemic,  we  have  received  either  provisional  registration,  conditional  marketing 
authorization, emergency use authorization, or full approval from the World Health Organization and various 
jurisdictions, and we 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  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 authorizations and approvals; 
• 
•  necessity  for  additional  nonclinical  or  clinical  studies,  changes  in  labeling,  or  changes  to 

voluntary or mandatory recalls of our products; 

manufacturing processes, specifications and/or facilities; 

impairment of our business reputation and negative media attention; 

• 
•  withdrawal of clinical trial participants; 
•  costs of related litigation; 

42

 
 
 
 
 
 
 
 
• 
• 
• 

substantial monetary awards to participants or other claimants; 

loss of revenue; and 
inability to commercialize our vaccine candidates. 

In  the  U.S.,  the  PREP  Act,  when  applicable,  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  invoke  the  PREP  Act  by  issuing  a 
declaration that a public health emergency or “credible risk” of a future public health emergency exists. 
Such a PREP Act declaration is separate from other declarations such as a PHE or EUA declaration and, 
among other things, defines the scope and duration of the PREP Act immunities. 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 evolving effects of 
COVID-19. The current declaration will end on December 31, 2024, unless it is renewed. While we believe 
our  products  are  covered  under  the  current  PREP  Act  declaration,  this  cannot  be  assured.  Also,  the 
Secretary of the DHHS may not make other declarations in the future that cover any of our other product 
candidates,  and  the  U.S.  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  COVID-19  Vaccine  in  sufficient  quantities,  at 
sufficient yields or are unable to obtain regulatory approvals for a manufacturing facility for our COVID-19 
Vaccine,  we  may  experience  delays  or  an  adverse  impact  on  product  development,  clinical  trials, 
regulatory approvals and commercial distribution. 

We  are  continuing  to  pursue  the  manufacture,  distribution  and  clinical  testing  of  our  COVID-19 
Vaccine  for  commercialization.  Completion  of  our  clinical  trials  and commercialization  of  our  COVID-19 
Vaccine and our other vaccine candidates requires access to, or development of, facilities to effectively 
manufacture  our  COVID-19  Vaccine  and  our  other  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  increased  our  global  manufacturing 
capacity for our COVID-19 Vaccine, our efforts to establish and maintain manufacturing capabilities may 
not meet expectations as to timing, scale-up, reproducibility, yields, purity, cost, potency or quality. We are 
highly  dependent  on  third-party  organizations  to  conduct  a  significant  amount  of  our  vaccine 
manufacturing activities. We do not have sufficient internal manufacturing infrastructure to support global 
commercialization  of  our  COVID-19  Vaccine  and  we  have  entered  into  third-party  agreements  for  the 
components,  as  well  as  for  commercial  fill-finish  manufacturing,  for  our  COVID-19  Vaccine.  The  antigen 
component of our COVID-19 Vaccine is currently being manufactured at SIIPL in India, and the Matrix-MTM 
adjuvant component of our COVID-19 Vaccine is currently being manufactured at Novavax AB as well as 
our  partnered  manufacturing  site  at  AGC  Biologics  in  Europe.  Challenges  in  manufacturing  either  the 
antigen component or the adjuvant, or issues in later manufacturing stages, could compromise production 
of  our  COVID-19  Vaccine.  Additionally,  we  currently  depend  substantially  on  SIIPL  and  SLS  for  co-
formulation, filling, and finishing our COVID-19 Vaccine (other than in Europe) and PCI for finishing in Europe, 
and any delays or disruptions in these suppliers’ operations could prevent or delay the delivery of customer 
orders. 

Additionally,  to  ensure  adequate  inventory  supply  and  manage  our  operations,  we  forecast 
anticipated  manufacturing  requirements  and  customer  demand  to  predict  inventory  needs  and  place 
orders  with  our  third-party  manufacturers  based  on  such  predictions.  Our  ability  to  accurately  forecast 
demand for our COVID-19 Vaccine could be negatively affected by many factors, including challenges in 
managing  our  commercial  strategy,  unanticipated  changes  in  general  market  conditions  or  regulatory 
matters, and market demand for variant-specific COVID-19 vaccines, among others. If we underestimate 
our  third-party  manufacturing  requirements,  we  may  not  be  able  to  timely  meet  obligations  under  our 

43

 
 
 
 
 
customer supply agreements. Conversely, if we overestimate our third-party manufacturing requirements, 
we may end up with inventory levels in excess of customer demand that result in a portion of our inventory 
becoming obsolete or expiring, as well as inventory write-downs or write-offs, or we may need to cancel 
previously forecasted batches of product from our third-party manufacturers, which may result in material 
cancellation fees. In September 2022, for example, we entered into a Confidential Settlement Agreement 
and Release with FUJIFILM under which we are responsible for up to $185 million to FUJIFILM in connection 
with the termination of manufacturing activity. In December 2022, we agreed to approximately $95 million 
in fees owed to AGC Biologics in connection with the cancellation of batches in 2022. If we are unable to 
accurately  forecast  demand  for  our  COVID-19  Vaccine  and  the  required  services  from  third-party 
manufacturers, our results of operations could be materially harmed. 

Manufacturing our COVID-19 Vaccine and our other vaccine candidates involves a complicated 
process  with  which  we  have  limited  experience.  If  we  and  our  third-party  manufacturers  are  unable  to 
manufacture our COVID-19 Vaccine and our other vaccine candidates in clinical quantities or, if and when 
necessary, in commercial quantities and at sufficient yields and at required specifications, then clinical trials 
and commercialization will be delayed, and we will need to identify and reach supply arrangements with 
additional  third  parties.  Third-party  manufacturers  also  must  receive  U.S.  FDA  or  equivalent  foreign 
regulatory body approval before they can produce clinical material or commercial product which could 
cause  delays  and  alter  our  production  schedule.  Our  COVID-19  vaccines  are  in  competition  with  other 
products for access to these third-party facilities and may be subject to delays in manufacture if third parties 
prioritize  other  products.  We  may  not  be  able  to  enter  into  any  necessary  additional  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. 

Because  of  contractual  restraints  and  the  limited  number  of  third-party  manufacturers  with  the 
expertise, required regulatory approvals and facilities to manufacture bulk vaccines at commercial-scale, 
replacement of a manufacturer may be expensive and time-consuming and may cause interruptions in 
the  production  of  our  vaccine  and  negatively  impact  our  ability  to  timely  meet  obligations  under  our 
customer  supply  agreements.  We  and  our  third-party  manufacturers  may  also  encounter  production 
challenges related to: 

shortages of raw materials and supplies; 

shipment delays or other supply chain disruptions 

•  costs, scale up, and yields; 
• 
• 
•  quality control and assurance; 
•  contamination, lot consistency, potency, and purity; 
• 
•  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 

shortages of qualified personnel and other capacity constraints; 

•  capital funding. 

Delays or interruptions 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  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 

44

 
 
 
 
 
 
 
 
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; 

• 

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. 

We are highly dependent on the commercial success of our COVID-19 Vaccine, and even though 
we  have  received  provisional  registration,  conditional  marketing  authorization  or  emergency  use 
authorization in certain jurisdictions for our COVID-19 Vaccine, and even if we have products licensed in 
additional markets, our vaccine products may not be initially or ever profitable. 

We are highly dependent on the commercial success of our COVID-19 Vaccine, which is currently 
our only commercial product and source of product revenues. 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 our COVID-19 Vaccine to certain 
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, and, ultimately, 
we may never generate sufficient revenues from our products to reach or maintain profitability or sustain 
our anticipated levels of operations. 

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 be subject to change and could adversely affect any commercial success of our 
vaccine candidates. 

45

 
 
 
 
 
 
 
 
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 and if obtained, 
maintain  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  product  has  not 
received appropriate clearances from the U.S. 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  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  drug  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.  Our  exposure  to  price-related 
regulation  could  depend  on  whether  our  products  are  reimbursed  by  Medicare  under  Part  B  or  Part  D. 
Medicare  Part  B  vaccine  coverage  includes  vaccines  to  prevent  influenza,  pneumococcal  disease, 
hepatitis B for beneficiaries who are at medium or high risk, and COVID-19. Vaccines for such conditions do 
not have any cost-sharing requirements. Meanwhile, Medicare Part D vaccine coverage includes all other 
commercially available vaccines that are determined to be reasonable and necessary to prevent illness. 
Part D vaccine coverage historically included cost-sharing requirements, but, effective January 1, 2023, the 
IRA provides access to CDC and ACIP-recommended vaccines covered under Medicare Part D without 
cost-sharing.

party reimbursement model. This transition to a more traditional third

Since  the  beginning  of  the  COVID-19  pandemic,  the  U.S.  federal  government  has  been  the 
predominant  purchaser  of  COVID-19  vaccines,  making  it  possible  for  population-wide  access  to 
vaccinations. This population-wide access may change as the pandemic moves past the crisis phase and 
the market transitions to a third
party 
reimbursement model is not tied to the ending of the PHE and in part reflects the fact that the U.S. federal 
government has not received additional funds from Congress to continue to purchase more vaccines. As 
federal funding declines for COVID-19 vaccines, the USG will most likely transition to standard commercial 
purchasing through different health care system channels, including commercial insurers and pharmacy 
benefit managers, and consequently shift the cost of COVID-19 vaccines to insurers and patients (in the 
form of premiums and out-of-network costs). With respect to the government health care programs and 
commercial insurance, there may no longer be blanket coverage of COVID-19 vaccines without, in certain 
instances,  accompanying  conditions  of  reimbursement,  such  as  the  institution  of  prior  authorization 
protocols.  Medicare  (including  traditional  Medicare  and  Medicare  Advantage)  will  continue  to  pay  for 
vaccinations  in  full;  effective  January  1,  2023,  all  Medicare  Part  D  plans  are  required  to  cover  all  adult 
vaccines  recommended  by  the  ACIP,  with  no  cost-sharing,  even  if  the  beneficiary  is  in  the  deductible 
phase of the benefit. Provisions in the ARPA and IRA require Medicaid (specifically, with respect to enrollees 
who receive coverage under traditional Medicaid and all Medicaid medically needy enrollees in specified 
states)  and  CHIP  programs

available compared to that of our competitors or not procured by pharmacies or other providers.

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  United  States 
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 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. 

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 commercialization of our COVID-19 Vaccine, 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 full regulatory 

approvals. 

Even if we receive full 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; 
• 
•  publicity concerning our products or competing products and treatments; and 
•  our ability to obtain sufficient third party insurance coverage or reimbursement. 

the effectiveness of our marketing and distribution strategy; 

47

 
 
 
 
 
 
 
 
 
If  our  vaccine  candidates  do  not  become  widely  accepted  by  physicians,  patients,  third-party 
payers  and  other  members  of  the  medical  community  as  well  as  the  relevant  public  health  authorities 
responsible for scheduling immunizations, 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 anticipate entering into additional regional collaborations. 
Our relationships with SIIPL, Takeda, and SK bioscience 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. 

Our product candidates are sensitive to shipping and storage 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  returned  or  out  of  date 
products. Failure to effectively maintain our supply logistics, by us or third parties, could lead to additional 
manufacturing costs and delays in our ability to supply required quantities for clinical trials or otherwise. 

Our  vaccine  candidates  could  become  subject  to  a  product  recall  which  could  harm  our 

reputation, business, and financial results. 

The U.S. 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  a  product  is  found.  A  government-mandated  or  voluntary  recall  by  us  or  our  strategic 
collaborators  could  occur  as  a  result  of  manufacturing  errors,  design  or  labeling  defects  or  other 
deficiencies and issues. For example, we have extended a credit of $64.7 million under the Australia APA 
for a single lot of NVX-CoV2373 doses sold to the Australian government that upon pre-planned 6-month 
stability  testing  was  found  to  have  fallen  below  the  defined  specifications,  and  the  lot  was  therefore 
removed from the market. Recalls of any of our vaccine candidates would divert managerial and financial 
resources and have an adverse effect on our financial condition and results of operations. Additionally, a 
recall announcement could harm our reputation with customers and negatively affect our sales. 

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 

48

 
 
 
 
 
 
 
 
 
 
 
 
 
public  research  institutions.  Many  of  our  competitors  have  significantly  greater  financial  and  technical 
resources, experience and expertise in: 

research and development; 

• 
•  peclinical testing; 
•  designing and implementing clinical trials; 
• 
regulatory processes and approvals; 
•  production and manufacturing; and 
• 

sales and marketing of approved products.  

Principal competitive factors in our industry include: 

the quality and breadth of an organization’s technology; 

• 
•  management of the organization and the execution of the organization’s strategy; 
• 

the skill and experience of an organization’s employees and its ability to recruit and retain skilled 
and experienced employees; 

•  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 
commercialization activities. 

resources 

to 

fund  discovery,  development  and 

Large and established companies, such as Merck & Co., Inc., GlaxoSmithKline plc, CSL Ltd., Sanofi 
Pasteur,  SA,  Pfizer  Inc.,  Johnson  &  Johnson,  AstraZeneca,  and  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 U.S. 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 and a combined 
vaccine against COVID-19 and influenza, and we may never see returns on the significant resources we 
are devoting to our vaccine candidates. 

Our  COVID-19  Vaccine  has  moved  rapidly  through  the  regulatory  review  and  authorization 
processes in the U.S. and other jurisdictions. The speed at which COVID-19 vaccines and therapeutics are 
being created  and tested  is  atypical,  and evolving or  changing plans  or  priorities  within  the U.S.  FDA or 
other  regulatory  authorities,  including  changes  based  on  new  knowledge  of  COVID-19  and  how  the

disease, and new variants of the virus, affect the human body, may significantly affect our ability to establish 
a  competitive  market  share  for  our  COVID-19  Vaccine.  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, and Pfizer/BioNTech have received full regulatory 
approvals for their COVID-19 vaccines and, along with Johnson & Johnson have received emergency use 
authorizations  for  their  COVID-19  vaccines  in  the  U.S.  and  other  countries.  All  of  these  companies  have 
obtained  the  relevant  Emergency  Use  Licenses  (“EULs”)  from  the  World  Health  Organization  for  their 
respective vaccines to be supplied to the countries or international coalition partners, including the relevant 
United  Nations  agencies,  which  rely  upon  the  World  Health  Organization’s  EULs  to  support  the  local 
immunization programs. 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 have 
developed  broad  market  acceptance  that  we  are  challenged  to  overcome.  The  U.S.  FDA  has  also 
approved Gilead’s Veklury (remdesivir) for treatment of COVID-19 in both adult and pediatric populations, 
as well as Eli Lilly’s Olumiant (baricitinib) and Genentech’s Actemra (tocilizumab) for treatment of COVID-19 
in certain hospitalized adults. 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  and 
commercialization of our COVID-19 Vaccine, 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 
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, be less expensive or quicker to manufacture, or contain other differentiating characteristics, 
such as being combined with another vaccine. Many competitors are working on new products and new 
generations of current products, intended to be more efficacious than those currently marketed. Our CIC 
vaccine  candidate  may  not  prove  to  be  more  efficacious  than  current  or  future  seasonal  influenza 
products  or  future  COVID-19  influenza  combination  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. 

Risks Related to Regulatory and Compliance Matters 

We may not succeed in obtaining full U.S. FDA licensure or foreign regulatory approvals necessary 

to sell our vaccine candidates. 

The development, manufacture and marketing of our pharmaceutical and biological products are 
subject to government regulation by the U.S. FDA and regulatory authorities in other jurisdictions, including 
the 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, 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 

50

 
 
 
 
 
 
 
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  has  yet  gained  full  regulatory  approval  in  the  U.S.,  although  our  COVID-19  Vaccine  has 
received provisional registration, conditional marketing authorization, emergency use authorization, or full 
approval  in  the  various  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 approvals. 

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

marketed in the U.S. include: 

•  performance of preclinical (animal and laboratory) tests; 
• 

submission  to  the  U.S.  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 U.S. FDA inspection; 

• 

submission to the U.S. FDA of a BLA or a NDA; and 

•  U.S.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. For example, the first batch of top line results 
from our Phase 2 CIC clinical trial evaluating safety and immunogenicity of different formulations of CIC 
may not be consistent with top line results from subsequent batches in such trial. 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 a regulatory authority 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  U.S.  FDA  and  foreign  regulatory  authorities  ultimately  may  not  grant  approval  for 
commercial sale in 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. 

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 

51

 
 
 
 
 
 
 
 
 
timely achieve requisite regulatory approval for our COVID-19 Vaccine in the relevant jurisdictions under 
such agreements. The speed with which we begin and complete the 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  scale-up  and  maintain  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 somewhat 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. 

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. 

If we are unable to effectively pursue the manufacture, clinical testing, regulatory authorization, and 
export of our COVID-19 Vaccine, or COVID-19 vaccines against future strain changes, we may encounter 
delays or challenges in commercially distributing these vaccines as well as gaining market acceptance for 
them. 

We expect that regulatory authorities will continue to monitor and assess SARS-CoV-2 evolution and 
recommend  that  manufacturers  make  corresponding  updates  to  the  composition  of  their  COVID-19 
vaccines at least annually. 

Inherent to this evolving approach to manufacturing new strains of COVID-19 vaccines, including 
our development of our COVID-19 Vaccine, we may encounter regulatory authorization, manufacturing, 

52

 
 
 
 
 
 
 
 
and  distribution  challenges,  including  export  challenges.  In  doing  so,  we  expect  to  seek  alignment  and 
acceptance  by  regulatory  authorities  that  would  allow  us  to  use  manufacturing  and  analytical  testing 
methods employed in earlier COVID-19 vaccine production and commercialization efforts, that support an 
accurate  characterization  profile  (including  purity,  potency,  stability  and  like  standards)  of  the  relevant 
COVID-19  vaccine.  Our  inability  to  overcome  product  development  challenges  and  gaining  regulatory 
authority alignment may adversely affect our ability to obtain licensure of our COVID-19 vaccine or future 
COVID-19 vaccines at all, or in a timely manner. 

Regarding  future  COVID-19  vaccine  development,  we  may  fail  to  receive  authorization  by 
regulatory authorities if we are unable to generate sufficient batch analysis data to demonstrate batch-to-
batch  consistency  at  commercial  scale,  if  the  data  generated  from  our  incremental  research  and 
development program do not support continued effectiveness of the vaccine to protect individuals against 
the  then-relevant  variant  of  SARS-CoV-2  because  the  vaccine  does  not  induce  an  adequate  level  of 
neutralization titers against such variant, or if the product otherwise exhibits an unacceptable safety profile, 
rendering the benefit/risk balance unfavorable. Moreover, the new vaccine lots may not be accepted for 
distribution if required batch-release testing undertaken by officially designated laboratories does not show 
that such vaccine is of acceptable quality. 

We  were  unable  to  accomplish  the  timely  validation  of  the  single-dose  vial  or  pre-filled  syringe 
presentation we had intended to use with the our COVID-19 Vaccine in the U.S. As a result, the five dose 
vial presentation for the fall 2023 vaccination season may have adversely impacted market acceptance, 
rate of product returns, or required higher price concessions in the U.S and may adversely impact us in the 
future if a single-dose or pre-filled syringe presentation is not authorized. 

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  supply agreements  with  various  foreign governments  and international 
distribution  agreements  with  commercial  entities.  In  order  to  market  our  products  in  various  countries 
globally, 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 U.S. 
FDA approval. The foreign regulatory approval process may include all of the risks associated with obtaining 
U.S.  FDA  approval.  Additionally,  regulatory  authorities  outside  the  U.S.  might  not  accept  data  from  trials 
conducted  in  other  countries.  Although  our  COVID-19  Vaccine  has  received  provisional  registration, 
conditional marketing authorization or emergency use authorization in a number of jurisdictions, we may 
not obtain regulatory approvals in other relevant jurisdictions on a timely basis, if at all. Approval by one 
regulatory agency does not ensure approval by regulatory agencies in other 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 U.S. FDA. The failure to obtain regulatory 
approval in foreign jurisdictions could harm our business. 

The  regulatory  pathway  for  our  COVID-19  Vaccine  is  continually  evolving  and  may  result  in 

unexpected or unforeseen challenges. 

The regulatory pathway for our COVID-19 Vaccine 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 the USG Agreement are uncertain and may evolve as the program progresses. 
Such rules or standards may adversely affect our plans to develop our COVID-19 Vaccine 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. 

53

 
 
 
 
 
 
 
 
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  U.S.  FDA,  the  EMA,  and  the  UK’s  Medicines  and  Healthcare  Products  Regulatory  Agency 
(“MHRA”) may make decisions more rapidly than is typical. Evolving or changing plans or priorities at the 
U.S. 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 our COVID-19 Vaccine. 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 U.S. 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  U.S.  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 our COVID-19 
Vaccine. 

In addition, because the path to licensure of any vaccine against COVID-19 is unclear, 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  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.  For  example, 
although we  currently  operate  under  an  emergency  use  authorization  provided  by  the  U.S.  FDA  for  our 
updated COVID-19 Vaccine, the U.S. FDA may revoke such authorization if it determines that the underlying 
health emergency no longer exists or warrants such authorization, and we cannot predict how long such 
authorization will remain in place. Such revocation could adversely impact our business in a variety of ways. 

We have conducted, continue to conduct and plan to conduct in the future, a number of clinical 
trials for our COVID-19 Vaccine at sites outside the U.S. and the U.S. FDA may not accept data from trials 
conducted in such locations.  

We have and are currently conducting several clinical trials of our COVID-19 Vaccine at sites outside 
the  U.S.,  including  a  Phase  3  pediatric  study  (2019nCoV-503)  in  the  Dominican  Republic,  Guatemala, 
Honduras,  the  Philippines,  and  Mexico.  Although  the  U.S.  FDA  may  accept  data  from  clinical  trials 
conducted outside the U.S., acceptance of these data is subject to conditions imposed by the U.S. 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 U.S. 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 BLA, U.S. 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 U.S. 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 and commercialization of our COVID-19 
Vaccine. 

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. 

Even after a product gains regulatory approval, the product and the manufacturer of the product 
will  be  subject  to  continuing  regulatory  review,  including  adverse  event  reporting  requirements  and 
prohibitions  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, 

54

 
 
 
 
 
 
 
 
injunctions,  suspensions  or  revocations  of  marketing  authorizations  or  licenses,  operating  restrictions  and 
criminal  prosecutions.  Any  such  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, 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. We cannot provide assurance that newly discovered or developed safety issues 
will  not  arise  following  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  appeared  to  be  unrelated  to  the  vaccine  itself  and  only  with  the  collection  of  subsequent 
information  were  found to  be causally  related  to  the 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 USG 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 our COVID-19 Vaccine, 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  U.S.  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  U.S.  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 U.S. 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 U.S. 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  USG  has  shut  down  several  times  and  certain 
regulatory agencies, such as the U.S. 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. 

55

 
 
 
 
 
 
 
 
 
Fast Track Designation by the U.S. 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 U.S. FDA Fast Track Designation or similar fast track processes with other regulatory agencies. In 
the EU and the UK, rolling review procedure was relied upon for conditional marketing authorizations to be 
granted. 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 U.S. 
FDA granted Fast Track Designation for our prototype vaccine in November 2020, and for 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 Designation, we may not 
experience  a  faster  development  process,  review  or  approval  compared  to  conventional  U.S.  FDA 
procedures. In addition, the U.S. 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 U.S. 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 U.S. FDA has granted such designation 
for our prototype vaccine, it may not actually result in faster clinical development or regulatory review or 
approval. Furthermore, such a designation does not increase the likelihood that our COVID-19 Vaccine 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. 

Our facilities in Maryland are subject to various local, state and federal laws and regulations relating 
to safe working conditions, laboratory 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  facilities  in 
Sweden, the Czech Republic, and Switzerland. 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  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 

56

 
 
 
 
 
 
 
 
and safety regulations. 

For  our  product  candidates,  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  full  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 (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 and regulations (which may be comparable to foreign laws existing 
in foreign countries) that may affect our ability to operate include: 

• 

• 

• 

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 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  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  U.S.,  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 

57

 
 
 
 
 
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. 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 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 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 UK 
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, and may impose modifications 
to business practices, including requiring the 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. 

58

 
 
 
 
 
 
 
Novavax  has  received  a  number  of  regulatory  approvals  in  ex-U.S.  jurisdictions  and  has 
commenced commercial operations in these international locations, including partnering with third-parties 
in  certain  higher-risk  jurisdictions.  Further,  a  portion  of  our  business  with  respect  to  our  manufacturing  is 
conducted outside of the U.S. in higher-risk jurisdictions. 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 630 U.S. and 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  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 any 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. 

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, and such risk has been enhanced by the departure of employees in connection with our global 
restructuring and cost reduction plan. 

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 U.S. 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 U.S. 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 

59

 
 
 
 
 
 
 
 
 
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 U.S. 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 be found 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  may  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.  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, 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  defend  or  enforce  our  intellectual  property  or  the 

intellectual 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 suits to prevent unauthorized uses. This can be expensive 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.  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. 

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 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. 

60

 
 
 
 
 
 
 
 
 
 
 
We may be subject to a variety of challenges from third 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  or  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 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.  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 
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, 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. 

We may need to license intellectual property from third 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. 

61

 
 
 
 
 
 
 
 
 
 
We have in the past, and we expect in the future to license intellectual property from third 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  may  not  control  either  the  prosecution  or  the  enforcement  of  the 
patents. Under 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. 

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. 
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,  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. 
In  Europe,  a  new  unitary  patent  system,  which  took  effect  on  June  1,  2023,  may  significantly  impact 
European  patents,  including  those  granted  before  the  introduction  of  the  new  system.  Under  the  new 
system, applicants can, upon grant of a patent, opt for that patent to become a Unitary Patent which will 
be  subject  to  the  jurisdiction  of  a  new  Unitary  Patent  Court  (“UPC”).  Patents  granted  before  the 
implementation of the new system can be opted out of UPC jurisdiction, remaining as national patents in 
the UPC countries. Patents that remain under the jurisdiction of the UPC may be challenged in a single UPC-
based  revocation  proceeding  that,  if  successful,  could  invalidate  the  patent  in  all  countries  who  are 
signatories to the UPC. Further, because the UPC is a new court system and there is no precedent for the 
court’s laws, there is increased uncertainty regarding the outcome of any patent litigation. We are unable 
to  predict  what  impact  the  new  patent  regime  may  have  on  our  ability  to  exclude  competitors  in  the 
European market. In addition to changes in patents laws, geopolitical dynamics, including Russia’s incursion 
into Ukraine, may also impact our ability to obtain and enforce patents in particular jurisdictions. If we are 
unable to obtain and enforce patents as needed in particular markets, our ability to exclude competitors 
in those markets may be reduced. 

62

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

In the U.S., 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 U.S. 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 
and the United Kingdom. 

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 U.S. 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 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 Employee 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. 

Given our current cash position and cash flow forecast, and significant uncertainties related to 2024 
revenue substantial  doubt  exists regarding  our  ability  to  continue  as  a  going concern  through  one year 
from the date that the financial statements included in this Annual Report were issued. 

63

 
 
 
 
 
 
 
 
 
 
 
Our  management  must  evaluate  whether  there  are  conditions  or  events,  considered  in  the 
aggregate, that raise substantial doubt about our ability to continue as a going concern within one year 
after the date the financial statements are issued. At December 31, 2023, we had $0.6 billion in cash and 
cash equivalents and restricted cash. During 2023, we incurred a net loss of $545.1 million and had net cash 
flows used in operating activities of $714.0 million. 

While our current cash flow forecast for the one-year going concern look forward period estimates 
that we have sufficient capital available to fund operations, this forecast is subject to significant uncertainty, 
including as it relates to the following: 

• 

2024  Revenue:  Our  2024  revenue  depends  on  our  ability  to  successfully  develop,  manufacture, 
distribute, or market an updated monovalent or bivalent formulation of a vaccine candidate for 
COVID-19 in a single dose vial or pre-filled syringe product presentation for the fall 2024 COVID-19 
vaccine season, which is inherently uncertain and subject to a number of risks, including regulatory 
authorizations  and  our  ability  to  introduce  a  single-dose  vial  or  pre-filled  syringe  product 
presentation for the U.S. commercial and certain other markets.  

Management believes that, given the significance of these uncertainties, substantial doubt exists 
regarding our ability to continue as a going concern through one year from the date that these financial 
statements are issued. 

Our ability to fund Company operations is dependent upon revenue related to vaccine sales for 
our products and product candidates, if such product candidates receive marketing approval and are 
successfully  commercialized;  the  resolution  of  certain  matters;  and  management’s  plans,  which  may 
include  raising  additional  capital  through  a  combination  of  equity  and  debt  financing,  collaborations, 
strategic  alliances,  and  marketing,  distribution,  or  licensing  arrangements.  New  financings  may  not  be 
available to us on commercially acceptable terms, or at all. Also, any collaborations, strategic alliances, 
and marketing, distribution, or licensing arrangements may require us to give up some or all of our rights to 
a product or technology, which in some cases may be at less than the full potential value of such rights. In 
addition,  the  regulatory  and  commercial  success  of  our  COVID-19  Vaccine  and  our  other  vaccine 
candidates, including CIC vaccine candidate, or future COVID-19 variant strain-containing monovalent or 
bivalent formulations, remains uncertain. If we are unable to obtain additional capital, we will assess our 
capital  resources  and  may  be  required  to  delay,  reduce  the  scope  of,  or  eliminate  some  or  all  of  our 
operations, or downsize our organization, any of which may have a material adverse effect on our business, 
financial condition, results of operations, and ability to operate as a going concern. 

Our  announced  global  restructuring  and  cost  reduction  plans  may  not  result  in  anticipated 
reductions in combined research and development and selling, general, and administrative expenses and 
may disrupt our business. 

In May 2023, we announced a global restructuring and cost reduction plan. This plan includes a 
more focused investment in our COVID-19 commercial program, reduction to our pipeline spending, the 
continued rationalization of our manufacturing network, a reduction to our global workforce, as well as the 
consolidation of facilities and infrastructure. The planned workforce reduction includes an approximately 
25% reduction in our global workforce, comprised of an approximately 20% reduction in full-time Novavax 
employees and the remainder comprised of contractors and consultants. We expect the full annual impact 
of the cost savings to be realized in 2024. During 2023, we recorded a charge of $4.5 million related to one-
time employee severance and benefit costs and $10.1 million costs related to the consolidation of facilities 
and infrastructure, the majority of which were incurred in the second quarter of 2023.  

Additionally, in January 2024 we announced an additional 12% reduction of our global workforce, 
comprised  of  an  additional  9%  reduction  in  the  Company’s  full-time  employees  and  the  remainder 
comprised of contractors and consultants. The Company expects the full annual impact of the cost savings 
to be realized in 2025 and approximately 85% of the annual impact, excluding one-time charges, to be 
realized in 2024 due to timing of implementing the measures and the applicable laws, regulations and other 

64

 
 
 
 
 
 
 
 
 
 
factors in the jurisdictions in which it operates. The Company is expected to record an additional charge of 
approximately  $4  million  to  $7  million  related  to  one-time  employee  severance  and  benefit  costs,  the 
majority  of  which  is  expected  to  be  incurred  in  the  first  quarter  of  2024.  Upon  completion,  the  resulting 
Company workforce is expected to be approximately 30% lower as compared to the end of the first quarter 
of 2023. 

We may not realize, in full or in part, the anticipated benefits, savings and improvements in our cost 
structure from these efforts due to unforeseen difficulties, delays or unexpected costs. If we are unable to 
realize  the  potential  development  progress  and  cost  savings  from  the  global  restructuring  and  cost 
reduction plan, including the reduction to our global workforce, our business strategy, operating results and 
financial  condition  would  be  adversely  affected.  Our  workforce  reductions  could  yield  unanticipated 
consequences,  such  as  attrition  beyond  planned  workforce  reductions  or  disruptions  in  our  day-to-day 
operations.  Our  global  restructuring  and  cost  reduction  plan,  including  the  reduction  to  our  global 
workforce,  could  also  harm  our  ability  to  attract  and  retain  qualified  management  and  development 
personnel  who  are  critical  to  our  business.  If  we  are  unable  to  realize  the  expected  benefits  from  the 
restructuring and cost reduction plan, we may decide to undertake additional workforce reductions. 

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, 
including 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. We are required 
to expend significant resources in an effort to protect against security incidents, and may be required or 
choose  to  spend  additional  resources  or  modify  our  business  activities,  particularly  where  required  by 
applicable data privacy and security laws or regulations or industry standards. Cyber attacks are of ever-
increasing  levels  of  sophistication  and  frequency  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. Our profile as a recipient of funding under the USG Agreement and our development 
of our COVID-19 Vaccine 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, 
or 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 on our data and systems, including malware 
and computer viruses. Additionally, we partner with sites that store our clinical trial data, and their systems 
are also subject to the risk of cyberattacks, disruptions, or other security incidents. 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  premiums,  any  of  which  could  have  a  material  adverse  effect  on  our  business,  operations  or 
financial results. 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  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,  fines,  and  other  harms 
which would cause our business and reputation to suffer. 

65

 
 
 
 
 
 
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 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  exercise  data  protection  rights  such  as  their  right  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. From January 1, 2021 the GDPR has been retained in UK, 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  UK’s  Data  Protection  Act  2018.  The  UK  GDPR 
mirrors the fines under the GDPR, i.e., fines up to the greater of €20 million (£17.5 million) or 4% of global 
turnover. 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 may be exposed to substantial 
penalties or litigation related to violations of existing or future data privacy laws and regulations.  

Furthermore, transferring personal information across international borders is complex and subject 
to legal and regulatory requirements as well as active litigation and enforcement in a number of jurisdictions 
around  the  world,  each  of  which  could  have  an  adverse  impact  on  our  ability  to  process  and  transfer 
personal  data  as  part  of  our  business  operations.  For  example,  the  GDPR  and  UK  GDPR  impose  strict 
restrictions  surrounding  the  transfer  of  personal  data  to  countries  outside  the  EEA  and  the  UK  The 
mechanisms  that  we  and  many  other  companies  rely  upon  for  European  data  transfers  (for  example, 
Standard Contractual Clauses and the EU - US Data Privacy Framework) are the subject of legal challenge, 
regulatory interpretation and judicial decisions by the Court of Justice of the European Union. The suitability 
of Standard Contractual Clauses for data transfer in some scenarios has recently been the subject of legal 
challenge, and while the United States and the European Union reached agreement on the EU - US Data 
Privacy Framework, there are legal challenges to that data transfer mechanism as well. We continue to 
closely monitor for developments related to valid transfer mechanisms available for transferring personal 
data  outside  the  European  Economic  Area  (including  the  EU  -  US  Data  Privacy  Framework)  and  other 
countries that have similar trans-border data flow requirements and adjust our practices accordingly. 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 U.S. An inability to import personal information from 
Europe to the U.S. 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.  Several  other  countries  have 
also established specific legal requirements for cross-border transfers of personal information and certain 
countries have also established specific legal requirements for data localization (such as where personal 
data must remain stored in the country). If other countries implement more restrictive regulations for cross-
border  data  transfers  or  do  not  permit  data  to  leave  the  country  of  origin,  such  developments  could 
adversely impact our business and our enterprise customers’ business, our financial condition and our results 
of operations in those jurisdictions. 

Privacy  laws  and  regulations  are  also  expanding  in  the  U.S.  For  example,  the  CCPA  requires 
disclosures  to  California  consumers,  imposes  rules  for  collecting  or  using  information  about  minors  and 
affords consumers 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. 

66

 
 
 
 
 
The  California  Privacy  Rights  Act  (“CPRA”),  became  operational  in  2023  and  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 and 
disclosure  of  sensitive  personal 
information.  Virginia,  Connecticut  and  Utah  have  also  passed 
comprehensive  privacy  laws  that  became  effective  in  2023,  and  similar  laws  have  been  passed  or  are 
being considered in several other states, as well as at the federal and local levels. We will need to evaluate 
and update our privacy program to seek to comply with the CPRA, VCDPA, CPA and other federal and 
state privacy and data security laws, and we expect to incur additional expense in our effort to comply. 

Such legislation 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. 

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 measures, including tariffs, embargoes, sanctions, 

import restrictions, 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 or our failure to implement an appropriate succession plan 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 

67

 
 
 
 
 
 
 
 
 
Company could result in operational and administrative inefficiencies and added costs. These risks have 
increased  since  our  global  restructuring  and  cost  reduction  plan  and  related  workforce  reduction 
implemented in May 2023 and January 2024, which increased the risk that we will lose technical know-how 
or other trade secrets as experienced personnel depart. 

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 Senior Notes 

Servicing our 5.00% convertible senior unsecured notes due 2027 requires a significant amount of 

cash, and we may not have sufficient cash flow to pay our debt. 

In  2022,  we  issued  $175.3  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 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  matures  in  2027,  unless  earlier  converted,  redeemed,  or  repurchased,  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. 

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  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 pursuant to the indenture governing 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. 

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,  2023  through  December  31,  2023,  the 
closing sale price of our common stock has been as low as $4.80 per share and as high as $12.48 per share. 

68

 
 
 
 
 
 
 
 
 
 
 
 
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. 
For example, the trading prices of biopharmaceutical companies in particular have been highly volatile as 
a result of the COVID-19 pandemic, inflation and increased interest rates. These broad market fluctuations 
may cause the market price of our common stock to be lower or more volatile than expected. 

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 our COVID-19 
Vaccine, 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 result of this volatility, you may not be 
able to sell your common stock at or above your initial purchase price. The market price of our common 
stock may 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; 
• 
•  announcement  by  us  of  significant  strategic  partnerships,  collaborations,  joint  ventures,  capital 

sale of equity securities or issuance of additional debt; 

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); 

litigation; 

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

•  development, spread or new announcements related to pandemic diseases; 
• 
•  public concern as to the safety of our products; 
• 
• 
•  demand for bivalent vaccines; 
• 
• 

recommendations by securities analysts or changes in earnings estimates; and 

the other factors described in this Risk Factors section. 

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

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. 

69

 
 
 
 
 
 
 
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 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’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.  For  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, 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. 

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

Given that COVID-19 represented an unprecedented urgent public health crisis and that we have 
received  significant  funding  from  the  U.S.  and  foreign  governments  and  other  sources  to  support  the 
development  and  commercialization  of  our  COVID-19  Vaccine,  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 our COVID-19 
Vaccine. 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 our COVID-19 Vaccine 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 1C. CYBERSECURITY 

Risk Management and Strategy 

The  Company  has  adopted  a  cybersecurity  risk  management  program  that  includes  processes 
designed  to  identify,  assess,  manage,  and  monitor  risks  from  cybersecurity  threats.  We  have  integrated 
cybersecurity risk management into our broader risk management framework to promote a company-wide 
culture  of  cybersecurity  awareness  and  risk  management.  Those  processes  include  conducting  an 
assessment  of  internal  and  external  threats  to  the  security,  confidentiality,  integrity  and  availability  of 
Company data and systems along with other material risks to Company operations, at least annually or 
whenever  there  are  material  changes  to  the  Company’s  systems  or  operations  and  responding  to  risks 
identified.  The  Company  uses  NIST  cybersecurity  and  risk  management  frameworks  to  assess  its 
cybersecurity controls, risks, and overall program effectiveness. As part of our risk management process, 
the Company also engages outside providers to conduct periodic internal and external penetration testing 
and security assessments. As part of our third-party risk management program, we conduct assessments of 
vendor cybersecurity risks, including risks associated with our cloud vendors and other third parties. 

As of the date of this report, we have not experienced a cybersecurity incident that resulted in a 
material effect on our business strategy, results of operations, or financial condition. Despite our continuing 
efforts, we cannot guarantee that our cybersecurity safeguards will prevent breaches or breakdowns of 
our  or  our  third-party  service  providers’  information  technology  systems,  particularly  in  the  face  of 
continually  evolving  cybersecurity  threats  and  increasingly  sophisticated  threat  actors.  For  example,  in 
2020, several domestic and foreign security agencies announced that government actors or government-
affiliated  actors  were  specifically  targeting  organizations,  like  us,  engaging  in  COVID-19  vaccine 
development and research. For more information, see Item 1A Risk Factors, “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.” 

Governance 

The  cybersecurity  risk  management  program  is  led  by  the  Company’s  Chief  Information  Officer 
(“CIO”) who has over 20 years of experience in information systems, cybersecurity, and data protection. 
The CIO reports to the Company’s Audit Committee at least annually, as well as to the Board of Directors, 
the Company’s Chief Executive Officer, and other members of our senior management as appropriate. 
These  reports  may  feature  an  overall  assessment  of  the  Company’s  compliance  with  the  Company’s 
cybersecurity policies and include topics such as risk assessment, risk management and control decisions, 
service  provider  arrangements,  test  results,  security  incidents  and  responses,  and  recommendations  for 
changes  and  updates  to  policies  and  procedures.  Our  program  is  evaluated  by  internal  and  external 
experts with the results of those reviews reported to senior management and the Board. 

Item 2. PROPERTIES 

As  of  December  31,  2023,  we  leased  approximately  170,000  square  feet  of  office  space  in 
Gaithersburg,  Maryland  that  serves  as  our  corporate  headquarters  (“700QO”),  and  intend  to  use  for 
manufacturing and research and development. The term of the 700QO lease agreement is approximately 
15 years, and we have the option to extend the Lease Agreement for two successive five-year terms. 

As of December 31, 2023, we also lease and own approximately 192,000 square feet of office and 
other space in the U.S., apart from our corporate headquarters and approximately 260,000 in various foreign 
locations.  We  use  this  space  for  our  services  and  support,  commercial,  research  and  development, 
manufacturing,  and  administrative  personnel.  Although  we  believe  that  our  facilities  are  suitable  and 
adequate  for  our  present  needs,  the  Company’s  management  continues  to  review  and  assess  real 
property requirements that may be necessary to address our current business plan.

Item 3. LEGAL PROCEEDINGS 

On November 12, 2021, Sothinathan Sinnathurai filed a purported securities class action in the U.S. 
District  Court  for  the  District  of  Maryland  (the  “Maryland  Court”)  against  the  Company  and  certain 
members of senior management, captioned Sothinathan Sinnathurai v. Novavax, Inc., et al., No. 8:21-cv-
02910-TDC  (the  “Sinnathurai  Action”).  On  January  26,  2022,  the  Maryland  Court  entered  an  order 
designating David Truong, Nuggehalli Balmukund Nandkumar, and Jeffrey Gabbert as co-lead plaintiffs in 
the Sinnathurai Action. The co-lead plaintiffs filed a consolidated amended complaint on March 11, 2022, 
alleging that the defendants made certain purportedly false and misleading statements concerning the 
Company’s ability to manufacture prototype vaccine on a commercial scale and to secure the prototype 
vaccine’s regulatory approval. The amended complaint defines the purported class as those stockholders 
who purchased the Company’s securities between February 24, 2021 and October 19, 2021. On April 25, 
2022, the defendants filed a motion to dismiss the consolidated amended complaint. On December 12, 
2022, the Maryland Court issued a ruling granting in part and denying in part defendants’ motion to dismiss. 
The Maryland Court dismissed all claims against two individual defendants and claims based on certain 
public statements challenged in the consolidated amended complaint. The Maryland Court denied the 
motion  to  dismiss  as  to  the  remaining  claims  and  defendants,  and  directed  the  Company  and  other 
remaining defendants to answer within fourteen days. On December 27, 2022, the Company filed its answer 
and  affirmative  defenses.  On  March  16,  2023,  the  plaintiffs  filed  a  motion  for  class  certification  and  to 
appoint class representatives and counsel. Due to the Maryland Court’s ruling on the dismissal motion, the 
motion sought to certify a class of stockholders who purchased the Company’s securities between May 11, 
2021, and October 19, 2021. The Company filed its opposition to the plaintiffs’ motion on September 22, 
2023.  On  December  4,  2023,  the  parties  agreed  to  a  binding  settlement  in  principle  (the  “Proposed 
Settlement”) to fully resolve the surviving claims in the Sinnathurai Action. Under the Proposed Settlement’s 
terms,  the  Company  agreed  to  pay  $47  million  into  a  settlement  fund,  which  will  be  funded  by  the 
Company’s directors and officers’ liability insurance and paid to members of a putative settlement class. 
On  January  12,  2024,  after  the  parties  negotiated  and  executed  a  written  agreement  governing  the 
Proposed  Settlement,  plaintiffs  filed  an  unopposed  motion  for  the  Proposed  Settlement’s  preliminary 
approval. On January 23, 2024, the Maryland Court granted the motion for preliminary approval and, as 
requested by the parties, preliminarily certified, for the purposes of settlement only, the settlement class. The 
court also scheduled a settlement hearing to consider final approval of the settlement for May 23, 2024. 

After  the  Sinnathurai  Action  was  filed,  eight  derivative  lawsuits  were  filed:  (i)  Robert  E.  Meyer  v. 
Stanley C. Erck, et al., No. 8:21-cv-02996-TDC (the “Meyer Action”), (ii) Shui Shing Yung v. Stanley C. Erck, et 
al., No. 8:21-cv-03248-TDC (the “Yung Action”), (iii) William Kirst, et al. v. Stanley C. Erck, et al., No. C-15-CV-
21-000618 (the “Kirst Action”), (iv) Amy Snyder v. Stanley C. Erck, et al., No. 8:22-cv-01415-TDC (the “Snyder 
Action”), (v) Charles R. Blackburn, et al. v. Stanley C. Erck, et al., No. 1:22-cv-01417-TDC (the “Blackburn 
Action”), (vi) Diego J. Mesa v. Stanley C. Erck, et al., No. 2022-0770-NAC (the “Mesa Action”), (vii) Sean 
Acosta v. Stanley C. Erck, et al., No. 2022-1133-NAC (the “Acosta Action”), and (viii) Jared Needelman v. 
Stanley C. Erck, et al., No. C-15-CV-23-001550 (the “Needelman Action”). The Meyer, Yung, Snyder, and 
Blackburn Actions were filed in the Maryland Court. The Kirst and Needelman Actions were filed in the Circuit 
Court for Montgomery County, Maryland. The Mesa and Acosta Actions were filed in the Delaware Court 
of Chancery (the “Delaware Court”). The derivative lawsuits name members of the Company’s board of 
directors and certain members of senior management as defendants. The Company is deemed a nominal 
defendant.  The  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. 

On  February  7,  2022,  the  Maryland  Court  entered  an  order  consolidating  the  Meyer  and  Yung 
Actions (the “First Consolidated Derivative Action”). The plaintiffs in the First Consolidated Derivative Action 
filed their consolidated derivative complaint on April 25, 2022. On May 10, 2022, the Maryland Court entered 
an order granting the parties’ request to stay all proceedings and deadlines pending the earlier of dismissal 
or the filing of an answer in the Sinnathurai Action. On June 10, 2022, the Snyder and Blackburn Actions 
were filed. On October 5, 2022, the Maryland Court entered an order granting a request by the plaintiffs in 

73

 
 
 
 
 
the  First  Consolidated  Derivative  Action  and  the  Snyder  and  Blackburn  Actions  to  consolidate  all  three 
actions  and  appoint  co-lead  plaintiffs  and  co-lead  and  liaison  counsel  (the  “Second  Consolidated 
Derivative Action”). The co-lead plaintiffs in the Second Consolidated Derivative Action filed a consolidated 
amended complaint on November 21, 2022. On February 10, 2023, defendants filed a motion to dismiss the 
Second Consolidated Derivative Action. The plaintiffs filed their opposition to the motion to dismiss on April 
11, 2023. Defendants filed their reply brief in further support of their motion to dismiss on May 11, 2023. On 
August 21, 2023, the court entered an order granting in part and denying in part the motion to dismiss; the 
court allowed claims for alleged insider selling under Brophy v. Cities Service Co., et al., 70 A.2d 5 (Del. Ch. 
1949)  and  unjust  enrichment  claims  to  proceed,  but  dismissed  the  remaining  claims  in  the  second 
consolidated  amended  complaint.  On  September  5,  2023,  the  Company  filed  an  Answer  to  the 
consolidated  amended  complaint.  On  September  6,  2023,  the  court  entered  an  order  granting  the 
individual defendants an extension of time to file their answer until November 6, 2023. On October 6, 2023, 
the  Board  of  Directors  of  the  Company  formed  a  Special  Litigation  Committee  (“SLC”)  with  full  and 
exclusive power and authority of the Board to, among other things, investigate, review, and analyze the 
facts and circumstances surrounding the claims asserted in the pending derivative actions, including the 
claims  that  remain  following  the  court’s  order  on  the  motion  to  dismiss  in  the  Second  Consolidated 
Derivative Action. On November 7, 2023, the court entered an order granting the parties’ request to stay 
the Second Consolidated Derivative Action for up to six months from the date of entry of the order. This 
includes  staying  the  deadline  for  the  individual  defendants  to  respond  to  the  consolidated  amended 
complaint. 

The  Kirst  Action  was  filed  on  December  28,  2021,  and  the  defendants  immediately  removed  the 
case to the Maryland Court. On July 21, 2022, the Maryland Court issued a memorandum opinion and order 
remanding the Kirst Action to state court. The plaintiffs filed an amended complaint on December 30, 2022. 
On January 23, 2023, defendants filed a motion to stay the Kirst action. On February 22, 2023, the parties in 
the Kirst Action filed, for the Court’s approval, a stipulation staying the Kirst Action pending the resolution of 
defendants’ motion to dismiss in the Second Consolidated Derivative Action. On March 22, 2023, the Court 
entered  the  parties’  stipulated  stay  of  the  Kirst  Action  pending  resolution  of  the  motion  to  dismiss  in  the 
Second Consolidated Derivative Action. 

On August 30, 2022, the Mesa Action was filed. On October 3, 2022, the Delaware Court entered 
an order granting the parties’ request to stay all proceedings and deadlines in the Mesa Action pending 
the earlier of dismissal of the Sinnathurai Action or the filing of an answer to the operative complaint in the 
Sinnathurai Action. On January 18, 2023, defendants filed a motion to stay the Mesa Action pending a final 
judgment  in  the  Second  Consolidated  Derivative  Action.  The  plaintiff  filed  his  opposition  on  February  8, 
2023.  Defendants  filed  their  reply  on  February  22,  2023.  On  February  28,  2023,  the  court  granted  the 
defendants’ motion to stay. On August 31, 2023, the plaintiff filed a motion to lift the stay. On October 6, 
2023, the Company filed an opposition to plaintiff’s motion to lift the stay. Plaintiff filed his reply on October 
17, 2023. On December 27, 2023, the parties filed a letter informing the Court that the Second Consolidated 
Derivative  Action  had  been  stayed  for  a  period  of  six  months  and  asked  the  Court  to  stay  further 
proceedings in the Mesa Action until expiration of that stay. 

On  December  7,  2022,  the  Acosta  Action  was  filed.  On  February  6,  2023,  defendants  accepted 
service of the complaint and summons in the Acosta Action. On March 9, 2023, the court entered an order 
granting  the  parties’  request  to  stay  the  Acosta  Action  pending  the  entry  of  a  final,  non-appealable 
judgment in the Second Consolidated Derivative Action. On October 13, 2023, the parties filed, and the 
Delaware Court entered, a stipulated order providing that (i) if the Delaware Court declines to lift the stay 
in the Mesa Action, the Acosta Action will also remain stayed, and (ii) if the Delaware Court lifts the stay in 
the Mesa Action, the stay in the Acosta Action will also be lifted. 

On April 17, 2023, the Needelman Action was filed. On July 12, 2023, the parties filed a stipulation 
and proposed order to stay the Needelman Action pending the Maryland Court’s decision on the motion 
to dismiss in the Second Consolidated Derivative Action. The court entered that order on July 17, 2023. The 
parties continue to discuss next steps in the litigation following the Maryland Court’s ruling on the motion to 
dismiss the Second Consolidated Derivative Action. The court entered that order on July 17, 2023. 

74

 
 
 
 
 
 
 
On November 30, 2023, the court entered an order consolidating the Kirst and Needelman Actions. 
On  December  14,  2023,  the  parties  filed  a  stipulation  (i)  extending  the  plaintiffs’  deadline  to  file  a 
consolidated complaint until January 29, 2024, and (ii) otherwise staying all other proceedings in the case 
(including the defendants’ deadline to respond to the consolidated complaint) until February 12, 2024. The 
stipulation entered by the court instructs the parties to discuss whether the stay should be further extended 
in light of the then-current status of the SLC’s investigation.  

On November 18, 2022, the Company delivered written notice to Gavi to terminate the Gavi APA 
based  on  Gavi’s  failure  to  procure  the  purchase  of  350  million  doses  of  prototype  vaccine  from  the 
Company as required by the Gavi APA. As of November 18, 2022, the Company had only received orders 
under the Gavi APA for approximately 2 million doses. On December 2, 2022, Gavi issued a written notice 
purporting  to  terminate  the  Gavi  APA  based  on  Gavi’s  contention  that  the  Company  repudiated  the 
agreement  and,  therefore,  materially  breached  the  Gavi  APA.  Gavi  also  contended  that,  based  on  its 
purported termination of the Gavi APA, it was entitled to a refund of the Advance Payment Amount less 
any amounts that have been credited against the purchase price for binding orders placed by a buyer 
participating  in  the  COVAX  Facility.  Since  December  31,  2022,  the  remaining  Gavi  Advance  Payment 
Amount, which is $696.4 million as of December 31, 2023, pending resolution of the dispute with Gavi related 
to a return of the remaining Advance Payment Amount, has been classified within Other current liabilities 
in the Company’s consolidated balance sheet. On January 24, 2023, Gavi filed a demand for arbitration 
with  the  International  Court  of  Arbitration  based  on  the  claims  described  above.  The  Company  filed  its 
Answer  and  Counterclaims  on  March  2,  2023.  On  April  5,  2023,  Gavi  filed  its  Reply  to  the  Company’s 
Counterclaims. On February 16, 2024, the Company and Gavi entered into a Termination and Settlement 
Agreement (the “Settlement Agreement”) terminating the Gavi APA, which related to the supply of the 
Company’s  vaccine  against  SARS-COV-2  for  the  prevention  of  COVID-19,  settling  the  arbitration 
proceedings initiated by Gavi against the Company relating to the APA and releasing both parties of all 
claims arising from, under or otherwise in connection with the APA. Pursuant to the Settlement Agreement, 
the Company is responsible for payment to Gavi of (i) an initial settlement payment of $75 million, which 
the Company paid on February 20, 2024, and (ii) deferred payments, in equal annual amounts of $80 million 
payable each calendar year through a deferred payment term ending December 31, 2028. The deferred 
payments  are  due  in  variable  quarterly  installments  beginning  in  the  first  quarter  of  2024  and  total  $400 
million during the deferred payment term. Such deferred payments may be reduced through Gavi’s use of 
an annual vaccine credit equivalent to the unpaid balance of such deferred payments each year, which 
may be applied to qualifying sales of any of the Company’s vaccines funded by Gavi for supply to certain 
low-income and lower-middle income countries. The Company has the right to price the vaccines offered 
to such low-income and lower-middle income countries in its discretion, and, when utilized by Gavi, the 
Company will credit the actual price per vaccine paid against the applicable credit. The Company intends 
to  price  vaccines  offered  via  the  tender  process,  consistent  with  its  shared  goal  with  Gavi  to  provide 
equitable access to those countries. On February 22, 2024, the claims and counterclaims were dismissed 
with prejudice. 

On  September  30,  2022,  the  Company,  FUJIFILM  Diosynth  Biotechnologies  UK  Limited  (“FDBK”), 
FUJIFILM  Diosynth  Biotechnologies  Texas,  LLC  (“FDBT”),  and  FUJIFILM  Diosynth  Biotechnologies  USA,  Inc. 
(“FDBU” and together with FDBK and FDBT, “Fujifilm”) entered into a Confidential Settlement Agreement 
and Release (the “Fujifilm Settlement Agreement”) regarding amounts due to Fujifilm in connection with 
the termination of manufacturing activity at FDBT under the Commercial Supply Agreement (the “CSA”) 
dated August 20, 2021 and Master Services Agreement dated June 30, 2020 and associated statements of 
work (the “MSA”) by and between the Company and Fujifilm. The MSA and CSA established the general 
terms and conditions applicable to Fujifilm’s manufacturing and supply activities related to the Company’s 
prototype vaccine under the associated statements of work. Pursuant to the Fujifilm Settlement Agreement, 
the Company agreed to pay up to $185.0 million (the “Settlement Payment”) to Fujifilm in connection with 
cancellation  of  manufacturing  activity  at  FDBT.  Under  the  Fujifilm  Settlement  Agreement,  the  final  two 
quarterly installments due to Fujifilm were subject to Fujifilm’s obligation to use commercially reasonable 
efforts to mitigate losses associated with the vacant manufacturing capacity caused by the termination of 
manufacturing activities at FDBT under the CSA. Any replacement revenue achieved by Fujifilm’s mitigation 
efforts between July 1, 2023 and December 31, 2023 would offset the final two settlement payments owed 
by the Company. On October 2, 2023, the Company sent a notice of breach under the Fujifilm Settlement 

75

 
 
 
 
Agreement  to  Fujifilm  setting  forth  the  Company’s  position  that  Fujifilm  had  not  used  commercially 
reasonable efforts to mitigate losses. The Company withheld two installments of $34.3 million due to Fujifilm 
on September 30, 2023 and December 31, 2023, pending resolution of the issues identified in the notice of 
breach. On October 30, 2023, FDBT filed a demand for arbitration with Judicial Arbitration and Mediation 
Services  (“JAMS”)  seeking  payment  of  the  third  quarter  installment  of  the  Settlement  Payment.  An 
arbitration hearing has been scheduled for May 2024. 

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 our financial 
position, results of operations, or cash flows.

Information in this Annual Report on Form 10-K, includes a financial measure that was not prepared 
in accordance with U.S. generally accepted accounting principles (“GAAP”), which we refer to as adjusted 
cost of sales. We are presenting this non-GAAP financial measure to assist an understanding of our business 
and its performance. Adjusted cost of sales includes an estimate of standard manufacturing costs that were 
previously expensed to research and development prior to regulatory approvals for our COVID-19 Vaccine 
that would otherwise have been capitalized to inventory. Any non-GAAP financial measures presented are 
not,  and  should  not  be  viewed  as,  substitutes  for  financial  measures  required  by  GAAP,  have  no 
standardized  meaning  prescribed  by  GAAP,  and  may  not  be  comparable  to  the  calculation  of  similar 
measures of other companies. 

Overview 

We are a biotechnology company that promotes improved global health through the discovery, 
development,  and  commercialization  of  innovative  vaccines  to  prevent  serious  infectious  diseases.  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. 

79

 
 
 
 
 
 
 
Our vaccine candidates are nanostructures of conformationally correct recombinant proteins that 
mimic those found on pathogens. This technology enables the immune system to recognize target proteins 
and  develop  protective  immune  responses.  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  some  other  vaccine  approaches.  Our  vaccine  candidates  also  incorporate  our  proprietary 
saponin-based Matrix-M™ adjuvant to enhance the immune response, stimulate higher levels of functional 
antibodies, and induce a cellular immune response. 

We  have  developed  an  updated  COVID-19  vaccine  for  the  2023-2024  vaccination  season.  In 
October  2023,  the  U.S.  FDA  granted  emergency  use  authorization  (“EUA”)  for  our  updated  vaccine  for 
active  immunization  to  prevent  COVID-19.  The  updated  vaccine  is  authorized  as  (1)  a  single  dose  in 
individuals 12 years and older who have been vaccinated with any COVID-19 vaccine at least 2 months 
after receipt of the last previous dose of COVID-19 vaccine, and (2) a series of 2 doses administered 3 weeks 
apart to individuals 12 years and older who were not previously vaccinated with any COVID-19 vaccine. 
Our updated vaccine is available within the U.S. at many major pharmacy retailers. Outside the U.S. for our 
updated  vaccine,  in  January  2024,  we  were  granted  marketing  authorization  by  the  United  Kingdom’s 
(“UK”)  Medicines  and  Healthcare  products  Regulatory  Agency  (“MHRA”),  in  December  2023,  we  were 
granted expanded authorization by Health Canada, and in October 2023, we were granted approval by 
the European Commission (“EC”). We are committed to meeting the full supply of our key target markets 
through advance purchase agreements (“APAs”) covering such markets. We continue to work closely with 
regulatory  authorities  globally  for  authorization  of  our  updated  vaccine.  We  previously  developed  a 
prototype COVID-19 vaccine, which has received full marketing authorization (“MA”), marketing approval, 
interim  authorization,  provisional  approval,  conditional  marketing  authorization  (“CMA”),  from  multiple 
regulatory authorities in over 40 countries globally. We continue to progress our regulatory authorizations for 
our prototype vaccine in select territories, as we believe these may facilitate authorization of our vaccine 
candidates for updated strains in the future. 

Additionally, we are developing a CIC vaccine candidate. In addition to COVID-19, our other areas 
of  focus  include  providing  Matrix-M™  adjuvant  for  collaborations,  including  in  R21/Matrix-M™  adjuvant 
malaria  vaccine,  which  recently  received  authorization  in  several  countries,  as  well  as  other  preclinical 
vaccine  research  with  our  Matrix-M™  adjuvant,  including  through  a  partnership  with  the  Bill  &  Melinda 
Gates Medical Research Institute. 

We intend to focus the organization to align our investments and activities with our top priority of 
delivering our updated vaccine for the 2023-2024 vaccination season. To maximize our opportunities and 
mitigate  the  significant  risks  and  uncertainties  of  the  COVID-19  market,  we  have  progressed  our  cost 
restructuring measures to reduce spend, extend our cash runway, and operate efficiently to seek to best 
position the Company to deliver longer-term growth. We discuss these cost restructuring strategies in greater 
detail in Note 2 to our consolidated financial statements in this Annual Report.

Financing Transactions 

In August 2023, we entered into an At Market Issuance Sales Agreement (the "August 2023 Sales 
Agreement"), which allows us to issue and sell up to $500 million in gross proceeds of shares of our common 
stock,  and  terminated  our  then-existing  At  Market  Issuance  Sales  agreement  entered  in  June  2021  (the 
“June 2021 Sales Agreement”). During the year ended December 31, 2023, we sold 38.3 million shares of 
our common stock under our August 2023 Sales Agreement and 7.9 million shares of our common stock 
under our June 2021 Sales Agreement, resulting in net proceeds of approximately $321 million, of which $6.9 
million was included in Prepaid expenses and other current assets as of December 31, 2023 and received 
in cash in January 2024. As of December 31, 2023, the remaining balance available under the August 2023 
Sales Agreement was approximately $242 million. 

During the year ended December 31, 2022, we sold 2.2 million shares of our common stock resulting 

in net proceeds of approximately $179 million, under our June 2021 Sales Agreement.  

In August 2023, pursuant to the Securities Subscription Agreement with SK, we agreed to sell and 
issue to SK 6.5 million shares of our common stock at a price of $13.00 per share (the “Shares”) in a Private 
Placement for aggregate gross proceeds to us of approximately $84.5 million. We recognized the Shares at 
the  settlement  date  fair  value  of  $46.5  million  (see  Note  4  to  our  consolidated  financial  statements  for 
additional discussion of the Securities Subscription Agreement with SK). The closing of the Private Placement 
occurred on August 10, 2023. 

In  December  2022,  we  completed  a  public  offering  of  7,475,000  shares  of  our  common  stock, 
including  975,000  shares  of  common  stock  that  were  issued  upon  the  exercise  in  full  of  the  option  to 

81

 
 
 
 
 
 
 
 
 
 
 
 
 
purchase  additional  shares  granted  to  the  underwriters,  at  a  price  of  $10.00  per  share  resulting  in  net 
proceeds,  net  of  offering  costs  of  $4.9  million,  of  approximately  $70  million.  We  completed  this  public 
offering  concurrent  with  the  issuance  of  the  2027  Notes  (see  Note  10  to  our  consolidated  financial 
statements). 

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 GAAP. 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 
as 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 product sales revenue, 
pre-launch  inventory,  inventory  realizability,  and  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. 

For  an  in-depth  discussion  of  each  of  our  significant  accounting  policies,  including  our  critical 
accounting  policies  and  further  information  regarding  estimates  and  assumptions  involved  in  their 
application, see Note 2 to the accompanying consolidated financial statements included in Part II, Item 8, 
“Financial Statements and Supplementary Data” of this Annual Report on Form 10-K. 

Revenue Recognition, Product Sales - Advance Purchase Agreements  

Product  sales  include  sales  associated  with  COVID-19  Vaccine  supply  agreements,  sometimes 
referred  to  as  advance  purchase  agreements  (“APAs”),  with  various  international  governments.  We 
recognize  revenue  from  product  sales  related  to  these  APA’s  based  on  the  transaction  price  per  dose 
calculated  in  accordance  with  Accounting  Standards  Codification  (“ASC”)  Topic  606,  Revenue  from 
Contracts with Customers, at the point in time when control of the product transfers to the customer and 
customer  acceptance  has  occurred,  unless  such  acceptance  provisions  are  deemed  perfunctory.  The 
APAs typically contain terms that include upfront payments which are reflected in Deferred revenue. We 
constrain the transaction price for APA’s until it is probable that a significant reversal in revenue recognized 
will not occur. Specifically, if an APA includes a provision whereby the customer may request a discount, 
return, or refund, or includes a term that may have the effect of decreasing the price per dose of previously 
delivered shipments, revenue is constrained based on an estimate of the impact of the transaction price 
until it is probable that a significant reversal in revenue recognized will not occur.  

Revenue Recognition, Product Sales - U.S. Commercial  

In the fourth quarter of 2023, we commenced sales of COVID-19 Vaccine to the U.S. commercial 
market. Product sales in the U.S. are primarily made through large pharmaceutical wholesale distributors at 
the wholesale acquisition cost (“WAC”). We recognize revenue upon title transfer (which is typically at time 
of delivery), provided all other revenue recognition criteria have been met. The transaction price includes 
estimates  of  variable  consideration  for  which  reserves  are  established  that  primarily  result  from  invoice 
discounts for prompt payment, wholesale distributor fees, chargebacks, and product returns (collectively, 
“gross-to-net deductions”). These estimates are based on the amounts earned or to be claimed for related 
sales and are classified as either reductions of gross accounts receivable or a current liability based on the 
nature of the estimate, the expected settlement method, and net position by individual customer. Where 
appropriate, these estimates are based on factors such as industry data and forecasted customer buying 
and  payment  patterns,  our  experience,  current  contractual  and  statutory  requirements,  specific  known 
market events, and trends. Variable consideration is included in the transaction price only to the extent 
that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur 
when the uncertainty associated with the variable consideration is subsequently resolved. If actual results 

82

 
 
 
 
 
 
 
 
 
vary  from  estimates,  we  will  adjust  the  estimates,  which  would  affect  product  sales  in  the  period  such 
variances become known.  

Gross-to-net deductions include the following: 

•  Wholesale distributor fees, discounts, and chargebacks: We have arrangements under which our 
indirect  customers  such  as  retailers  and  healthcare  providers  receive  discounts  to  the  WAC.  The 
chargeback represents the difference between the WAC and this negotiated discounted price. For 
distribution and related services, we pay service fees to our wholesale distributors. In addition, we 
typically  offer  wholesale  distributor  customers  invoice  discounts  on  product  sales  for  prompt 
payments. We estimate chargebacks, discounts, and fees we will owe and deduct these amounts 
from gross product sales at the time the revenue is recognized based on the contractual terms and 
our expectations regarding future customer behaviors. 

•  Product returns: We offer U.S. customers the right to return COVID-19 Vaccine. These return rights 
include the right of wholesale distributors to return unsold and expired doses and the right of indirect 
customers to return any partial or unused vials upon expiry. Estimated returns for COVID-19 Vaccine 
are  determined  considering  levels  of  inventory  in  the  distribution  channel,  projected  market 
demand, utilization data, returns claims received, and product shelf life. Our estimates of product 
returns  are  subject  to  significant  uncertainty.  Actual  customer  product  returns  could  vary 
significantly  from  our  estimates,  resulting  in  changes  to  the  estimates  in  subsequent  periods.  The 
estimated amount for product returns is deducted from gross product sales in the period the related 
product sales are recognized. 

•  Other: Fees payable to retailers, healthcare providers, and buying groups, including certain patient 
assistance programs, are deducted from gross product sales in the period the related product sales 
are recognized. 

During  the  year  ended  December  31,  2023,  we  recognized  gross-to-net  deductions  against  U.S. 
commercial product sales of $84.7 million for product returns and $47.0 million for wholesale distributor fees, 
discounts and chargebacks. As of December 31, 2023, $82.5 million related to product returns and $20.6 
million  related  to  wholesale distributor  fees,  discounts,  and chargebacks  were  included  in  Other  current 
liabilities and $2.6 million was included in Accounts receivable on our consolidated balance sheet. 

Pre-Launch Inventory 

We  capitalize  raw  materials  and  production  costs  as  inventory  when  we  determine  that 
commercialization of a product is probable and have a present right to the economic benefit associated 
with the product. Our estimate of when commercialization is probable is based primarily on our experience 
with obtaining regulatory approval of comparable products. We began to capitalize inventory in 2022. 

Inventory Realizability 

We  periodically  analyze  our  inventories  for  excess  amounts  or  obsolescence  and  write  down 
obsolete or otherwise unmarketable inventory to its estimated net realizable value. We estimate excess or 
obsolete  inventory  and  losses  on  firm  purchase  commitments  of  inventory  quarterly  based  on  multiple 
factors, including assumptions about expected future demand and market conditions, current sales orders, 
and product expiry dates. Our assumptions about expected future demand are inherently uncertain and 
if we were to change any of these judgments or estimates, it could cause a material increase or decrease 
in  the  amount  of  inventory  write  down  that  we  report  in  a  particular  period.  We  began  to  capitalize 
inventory in 2022. Subsequently, for the year ended, December 31, 2022 we recorded inventory write-downs 
of $447.6 million and losses on firm purchase commitments of inventory of $155.9 million to the extent the 
cost cannot be recovered based on estimates about future demand. For the year ended December 31, 
2023,  we  recorded  inventory  write-downs  of  $72.4  million  and  losses  on  firm  purchase  commitments  of 
inventory of $73.5 million. In addition, for the year ended December 31, 2023, we recorded recoveries on 
firm  purchase  commitments  of  $40.2  million  related  primarily  to  negotiated  reductions  to  previously 
recognized firm purchase commitments.

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  we  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 
contract  development  and  manufacturing  organizations  (“CDMOs”)  agreements,  including 
expenses incurred for the procurement of raw materials, laboratory supplies and equipment. 

We base our expenses on our estimates of the services provided and efforts expended pursuant to 
contracts,  statements  of  work  and  related  change  orders  with  the  service  provider,  and  discussion  with 
internal personnel and external service providers as to the progress of the services and the agreed-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 expense. 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 period. The 
estimation  process  requires  us  to  make  significant  judgments  and  estimates  in  determining  the  services 
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 nature of the estimation process, there may be a difference between estimated costs and actual 
costs incurred. Historically, we have not experienced any material differences in prior periods.

Revenue for the year ended December 31, 2023 was $983.7 million as compared to $2.0 billion for 
the year ended December 31, 2022, a decrease of $1.0 billion. Revenue for the years ended December 31, 
2023 and 2022 was primarily comprised of revenue from product sales of COVID-19 Vaccine and services 
performed  under  our  U.S.  government  agreement  with  Advanced  Technology  International  (“USG 
Agreement”),  the  Consortium  Management  Firm  acting  on  behalf  of  the  Medical  CBRN  Defense 
Consortium in connection with the partnership formerly known as Operation Warp Speed. The decrease in 
revenue is primarily due to a decreased quantity of dose sales of COVID-19 Vaccine. 

Product sales 

Product sales for 2023 were $531.4 million as compared to $1.6 billion for 2022, a decrease of $1.0 
billion. The decrease in product sales is primarily due to a decreased quantity of dose sales of COVID-19 
Vaccine during the year ended December 31, 2023 as compared to 2022. Product sales for 2023 related 
to  revenue  from  commercial  sales  of  COVID-19  Vaccine,  which  commenced  in  2022.  The  geographic 
distribution of product sales in 2023 was as follows:

Grant revenue for 2023 was $427.3 million compared to $382.9 million for 2022, an increase of $44.4 
million. Grant revenue comprised revenue for services performed under our USG Agreement. The increase 
was primarily due to increased support activities under the USG Agreement during 2023. As of December 
31, 2023, the Company has recognized the full contract funding under the USG Agreement in revenue.  

Royalties and Other 

Royalties  and  other  includes  royalty  milestone  payments,  sales-based  royalties,  and  Matrix-M™ 
adjuvant sales. Royalties and other revenue for 2023 was $25.0 million as compared to $44.0 million for 2022, 
a decrease of $19.0 million. The decrease was primarily due to decreased revenue related to milestone 
payments, partially offset by an increase in Matrix-M™ adjuvant sales.

Cost of sales was $343.8 million, or 65% of product sales, for the year ended December 31, 2023, 
including expense of $145.9 million related to excess, obsolete, or expired inventory and losses on certain 
firm purchase commitments, $6.1 million ROU asset impairment charges for CMO manufacturing capacity 
of excess quantities, $64.0 million related to unutilized manufacturing capacity, and a credit of $40.2 million 
related to negotiated reductions to certain previously recognized firm purchase commitments. Cost of sales 
was $902.6 million, or 58% of product sales, for 2022, including expense of $603.5 million related to excess, 
obsolete, or expired inventory and losses on firm purchase commitments. 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.  If  inventory  sold  during  2023  was  valued  at  expected  standard  cost,  including  expenses 
related to excess and obsolete inventory, adjusted cost of sales for the year would have been $382.8 million, 
an adjustment of $39.0 million as compared to cost of sales recognized. If inventory sold during 2022 was 
valued at expected standard cost, adjusted cost of sales for the year would have been approximately $1.1 
billion, an adjustment of $164.8 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 

Research  and development  expenses  decreased to  $737.5 million  for  2023 as  compared  to  $1.2 
billion  for  2022,  a  decrease  of  $497.8  million.  The  decrease  was  primarily  due  to  a  reduction  in  overall 
expenditures relating to development activities on coronavirus vaccines, including our COVID-19 Vaccine 
and CIC, as summarized in the table below (in thousands):

Research and development expenses for coronavirus vaccines for the year ended December 31, 
2023  and  2022  decreased  to  $413.4  million  from  $848.0  million  primarily  as  a  result  of  a  reduction  in 
manufacturing  and  support  costs  due,  in  part,  to  a  reduction  in  our  global  manufacturing  footprint 
consistent  with  our  contractual  obligations  to  supply,  and  anticipated  demand  for,  COVID-19  Vaccine, 
including  under  manufacturing  supply  agreements  with  CMOs  and  CDMOs,  and  a  reduction  in  clinical 
study costs and the commercialization of internal manufacturing capabilities. The decrease was also due 
to  a  benefit  of  $57.7  million  during  the  year  ended  December  31,  2023  resulting  from  our  settlement

agreement  and  Private  Placement  with  SK  (see  Note  4  to  our  consolidated  financial  statements).  The 
decrease was partially offset by a benefit of $35.2 million and $201.4 million for the years ended December 
31, 2023 and 2022, respectively, related to previously accelerated manufacturing costs for leases that we 
determined were embedded in manufacturing supply agreements with CMOs and CDMOs. 

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 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 2024, we expect research and development expenses to decrease as compared to 2023 as we 
continue to assess our manufacturing needs and modify our global manufacturing footprint consistent with 
our contractual obligations to supply, and anticipated demand for, COVID-19 Vaccine and as additional 
manufacturing activities that were previously recognized as research and development expenses begin to 
meet the criteria for capitalization as inventory. 

Selling, General, and Administrative Expenses 

Selling, general, and administrative expenses decreased to $468.9 million for 2023 from $488.7 million 
for  2022,  a  decrease  of  $19.7  million.  The  decrease  in  selling,  general,  and  administrative  expenses  is 
primarily  due  to  cost  containment  measures  to  reduce  our  operating  spend  including  a  decrease  in 
professional fees and advertising and promotion costs in support of our COVID-19 commercial program, 
partially offset by restructuring expenses.

favorable  impact  in  2023  as  compared  to  2022  of  exchange  rates  on  foreign  currency  denominated 
balances, including an intercompany loan with Novavax CZ, and an increase in investment income due to

share, for 2022, a decrease of $112.9 million, or $3.01 per share. The decrease in net loss was primarily due 
to  the  decline  in  cost  of  sales  and  research  and  development  expenses  associated  with  our  COVID-19 
Vaccine, partially offset by a decrease in revenue from product sales.  

The  increase  in  weighted  average  shares  outstanding  for  2023  is  primarily  a  result  of  sales  of  our 

common stock. 

Liquidity Matters and Capital Resources 

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; repayments 
under our grant agreements; our projected activities related to the development and commercial support 
of our COVID-19 Vaccine and our CIC vaccine candidate, 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  potential  combination 
vaccines candidates, which are in various stages of development. 

We have entered into supply agreements, sometimes referred to as APAs, with the EC and various 
countries globally. We also have license agreements. As of December 31, 2023, 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 $2 
billion, of which $863.5 million is included in Deferred revenue on our consolidated balance sheet. Failure 
to timely meet regulatory milestones, or achieve product volume or delivery timing obligations under our 
APAs may require us to refund portions of upfront or other payments or result in reduced future payments, 
which could adversely impact our ability to realize revenue from our unsatisfied performance obligations. 
The timing to fulfill performance obligations related to supply agreements will depend on timing of product 
manufacturing, receipt of marketing authorizations for additional indications, delivery of doses based on 
customer demand, and the ability of the customer to request variant vaccine in place of the prototype 
vaccine  under  certain  of  our  APAs.  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  COVID-19  Vaccine.  Such  upfront  payments 
generally  become  non-refundable  upon  our  achievement  of  certain  development,  regulatory,  and 
commercial milestones. 

On October 3, 2023, our updated vaccine received EUA from the U.S. FDA for active immunization 
to  prevent  COVID-19  in  individuals  aged  12  and  older.  Immediately  upon  authorization,  our  updated 
vaccine  has  also  been  included  in  the  recommendations  issued  by  the  CDC  in  September  2023.  Doses 
became  available  within  the  U.S.  at  many  major  pharmacy  retailers,  following  the  Center  for  Biologics

Evaluation  and  Research  release  of  vaccine  batches.  We  have  established  reserves  for  gross-to-net 
deductions for amounts that we expect to return to our customers. As of December 31, 2023, gross-to-net 
reserve  balances  are  $84.6  million  related  to  product  returns  and  $21.1  million  related  to  wholesale 
distributor fees, discounts, and chargebacks, of which $103.1 million is included in Accrued expenses and 
$2.6 million is included in Accounts receivable on our consolidated balance sheet.  

Pursuant to the Fujifilm Settlement Agreement (see Note 4 to our consolidated financial statements), 
we  agreed  to  pay  up  to  $185.0  million  (the  “Settlement  Payment”)  to  Fujifilm  in  connection  with  the 
cancellation of manufacturing activity at FDBT under the Fujifilm CSA, of which (i) $47.8 million, constituting 
the initial reservation fee under the CSA, was credited against the Settlement Payment on September 30, 
2022 and (ii) the remaining balance was to be paid in four equal quarterly installments of $34.3 million each, 
which  began  on  March  31,  2023.  Under  the  Fujifilm  Settlement  Agreement,  the  final  two  quarterly 
installments due to Fujifilm were subject to Fujifilm’s obligation to use commercially reasonable efforts to 
mitigate  losses  associated  with  the  vacant  manufacturing  capacity  caused  by  the  termination  of 
manufacturing activities at FDBT under the CSA. Any replacement revenue achieved by Fujifilm’s mitigation 
efforts between July 1, 2023 and December 31, 2023 would offset the final two settlement payments owed 
by the Company. On October 2, 2023, we sent a notice of breach under the Fujifilm Settlement Agreement 
to Fujifilm setting forth the Company’s position that Fujifilm had not used commercially reasonable efforts 
to mitigate losses. We withheld two installments of $34.3 million due to Fujifilm on September 30, 2023 and 
December 31, 2023, pending resolution of the issues identified in the notice of breach. We paid the first two 
installments totaling $68.6 million during the twelve months ended December 31, 2023, and the remaining 
balance of $68.6 million is reflected in Accrued expenses on our consolidated balance sheet. On October 
30,  2023,  FDBT  filed  a  demand  for  arbitration  with  Judicial  Arbitration  and  Mediation  Services  (“JAMS”) 
seeking payment of the third quarter installment of the Settlement Payment.  

In  August  2023, we  entered into a Settlement  Agreement and General Release (the  “Settlement 
Agreement”) with SK regarding the mutual release by the parties of all claims arising from or in relation to 
certain statements of work (“SOWs”) under the Development and Supply Agreement entered into in August 
2020  and  the  Collaboration  and  License  Agreement,  entered  into  in  February  2021  as  amended  in 
December 2021 and July 2022 in connection with the cessation of all drug substance and drug product 
manufacturing activity at SK for supply to us. Pursuant to the Settlement Agreement, we agreed to pay 
$149.8 million, of which (i) $130.4 million was paid in August 2023 and (ii) the remaining balance was paid 
in November 2023. Under the Settlement Agreement, we also agreed with SK to a wind down plan with 
respect  to  the  remaining  products,  materials  and  equipment  under  the  SOWs  (see  Note  4  to  our 
consolidated financial statements). 

In August 2023, we entered into a Securities Subscription Agreement (the “Subscription Agreement”) 
with  SK,  pursuant  to  which  we  agreed  to  sell  and  issue  to  SK,  in  a  private  placement  (the  “Private 
Placement”), 6.5 million shares of our common stock, par value $0.01 per share at a price of $13.00 per 
share  for  aggregate  gross  proceeds  to  us  of  approximately  $84.5  million.  The  closing  of  the  Private 
Placement occurred on August 10, 2023 (see Note 4 to our consolidated financial statements). 

We  have  an  APA  with  the  Commonwealth  of  Australia  for  the  purchase  of  doses  of  COVID-19 
Vaccine (the “Australia APA”). In April 2023, we amended the Australia APA to reduce the number of doses 
to be delivered with a commensurate increase in the per-dose price, such that the total contract value of 
the Australia APA is maintained with doses to be delivered through 2024. In May 2023, we extended a credit 
for certain doses delivered in 2022 to Australia that qualified for replacement under the Australia APA. This 
credit is the result of a single lot sold to the Australian government that upon pre-planned 6-month stability 
testing was found to have fallen below the defined specifications and the lot therefore was removed from 
the market. The credit will be applied against the future sale of doses to Australia. In July 2023, we amended 
the Australia APA to provide for replacement doses and to extend the delivery schedule through 2025. As 
of February 2024, we had not yet received TGA authorization or delivered doses as contemplated in the 
July  2023  amendment  and  are  in  active  discussions  with  the  Australian  government  on  both  the  TGA 
authorization and delivery of the doses previously scheduled for the fourth quarter of 2023. In February 2024, 
we  received  notice  from  the  Australian  government  purporting  to  cancel  its  order  for  such  prototype 
vaccine doses. We believe the cancellation was not proper under the amended Australia APA. However, 

89

 
 
 
 
 
 
if  such  a  cancellation  were  determined  to  be  allowable,  $6.0  million  of  the  deferred  revenue  would 
become a credit towards future deliveries of doses and approximately $48 million of the contract value 
related to future deliverables would no longer be available. 

In April 2023, we amended the Canada APA, pursuant to which the Canadian government forfeited 
certain doses originally scheduled for delivery in 2022 for a payment of $100.4 million, which we received in 
the  second  quarter  of  2023.  In  June  2023,  we  entered  into  an  additional  amendment  (the  “June  2023 
Amendment”) to the Canada APA. Pursuant to the June 2023 Amendment, (i) the Canadian government 
forfeited certain doses of COVID-19 Vaccine previously scheduled for delivery and agreed to pay a total 
amount of $349.6 million to us in two equal installments, which total amount equaled the remaining balance 
owed by the Canadian government with respect to such forfeited vaccine doses, (ii) the amount of doses 
of COVID-19 Vaccine due for delivery was reduced, (iii) the delivery schedule for the remaining doses of 
COVID-19  Vaccine  to  be  delivered  was  revised,  and  (iv)  the  parties  agreed  Novavax  would  use  the 
Biologics Manufacturing Centre (“BMC”) Inc. to produce bulk antigen for doses in 2024 and 2025. The June 
2023 Amendment maintained the total contract value of the original Canada APA. The first Installment of 
$174.8 million was payable upon execution of the June 2023 Amendment and received by Novavax in July 
2023,  and  the  second  installment  of  $174.8  million  was  contingent  and  payable  upon  the  delivery  of 
vaccine  doses  in  the  second  half  of  2023  and  received  by  Novavax  in  January  2024.  The  Canadian 
government may terminate the Canada APA, as amended, if we fail to receive regulatory approval for our 
COVID-19 Vaccine using bulk antigen produced at BMC on or before December 31, 2024. Our 2024 plans 
do  not  currently  anticipate  the  submission  for  regulatory  approval  of  our  COVID-19  Vaccine  using  bulk 
antigen produced at BMC, and we plan to work with the Canadian government on an amendment that 
addresses possible alternatives, which may not be achievable. As of December 31, 2023, $102.8 million was 
classified as short-term Deferred revenue and $485.3 million was classified as long-term Deferred revenue 
with  respect  to  the  Canadian  APA  on  our  consolidated  balance  sheet.  If  the  Canadian  government 
terminates  the  Canada  APA,  $28.0  million  of  the  deferred  revenue  would  become  refundable  and 
approximately $224 million of the contract value related to future deliverables would no longer be available 
(see  Note  3  to  our  consolidated  financial  statements).  In  the  event  that  the  contract  is  terminated,  we 
would consider competing in the Canadian commercial market. Pursuant to the June 2023 Amendment, 
we and the Canadian government will endeavor to expand our previously agreed in-country commitment 
to Canada and to partner to provide health, economic, and future pandemic preparedness benefits to 
Canada, which value may be provided through a number of activities, including without limitation, capital 
investments, the performance of activities or services, or the provision of technology or intellectual property 
licenses. Further, the parties will endeavor to enter into a memorandum of understanding (the “MOU”) to 
illustrate our ability to deliver such benefits over a 15-year period with an aggregate value of not less than 
100% of the amount remaining to be paid under the June 2023 Amendment and ultimately received by us. 
As of December 31, 2023, discussions regarding the MOU were ongoing. We agreed to hold $20.0 million of 
the  second  installment  payment  received  in  January  2024  in  escrow  for  the  benefit  of  the  Canadian 
government, which amount is the sole recourse available to the Canadian government in the event of non-
performance under the MOU.  

In  September  2022,  we  entered  into  an  Amended  and  Restated  SARS-CoV-2  Vaccine  Supply 
Agreement (the “Amended and Restated UK Supply Agreement”) with the Authority. Under the terms of 
the Amended and Restated UK Supply Agreement, the Authority agreed to purchase a minimum of 1 million 
doses and up to an additional 15 million doses (the “Conditional Doses”) of our prototype vaccine, with the 
number of Conditional Doses contingent on, and subject to reduction based on, our timely achievement 
of supportive recommendations from the JCVI that is approved by the UK Secretary of State for Health. If 
the Authority did not purchase the Conditional Doses or the number of such Conditional Doses was reduced 
below 15 million doses of our prototype vaccine, we would have to repay up to $225.0 million related to 
the upfront payment previously received from the Authority under the Original UK Supply Agreement. Under 
the Amended and Restated UK Supply Agreement, the Authority also has the option to purchase up to an 
additional 44 million doses, in one or more tranches, through 2024. 

As of November 30, 2022, the JCVI had not made a supportive recommendation with respect to 
our  prototype  vaccine,  thereby  triggering,  under  the  terms  of  the  Amended  and  Restated  UK  Supply 
Agreement, (i) a reduction of the number of Conditional Doses from 15 million doses to 7.5 million doses, 

90

 
 
 
 
 
which reduced number of Conditional Doses are contingent on, and subject to further reduction based 
on,  our  timely  achievement  by  November  30,  2023  of  a  supportive  recommendation  from  JCVI  that  is 
approved  by  the  UK  Secretary  of  State  for  Health  as  described  in  the  paragraph  above,  and  (ii)  an 
obligation  for  us  to  repay  $112.5  million  related  to  the  upfront  payment  previously  received  from  the 
Authority under the Original UK Supply Agreement. In April 2023, we repaid the $112.5 million related to the 
November  30,  2022  triggering  event.  As  of  November  30,  2023,  the  JCVI  had  not  made  a  supportive 
recommendation with respect to the prototype vaccine, thereby triggering a reduction in the number of 
Conditional Doses from 7.5 million doses to zero. As of February 2024, the Company is in discussions with the 
Authority regarding the treatment of the remaining upfront amount previously received of $112.5 million, 
which is reflected in Other current liabilities on our consolidated balance sheet.  

Under the terms of the Gavi APA, we received an upfront payment of $350.0 million from Gavi in 
2021 and an additional payment of $350.0 million in 2022 related to our achieving EUL for our prototype 
vaccine  by  the  WHO  (the  “Advance  Payment  Amount”).  On  November  18,  2022,  we  delivered  written 
notice  to  Gavi  to  terminate  the  Gavi  APA  on  the  basis  of  Gavi’s  failure  to  procure  the  purchase  of  350 
million doses of our prototype vaccine from us as required by the Gavi APA. As of November 18, 2022, we 
had only received orders under the Gavi APA for approximately 2 million doses. On December 2, 2022, Gavi 
issued a written notice purporting to terminate the Gavi APA based on Gavi’s contention that the Company 
repudiated the agreement and, therefore, materially breached the Gavi APA. Gavi also contended that, 
based on its purported termination of the Gavi APA, it was entitled to a refund of the Advance Payment 
Amount less any amounts that have been credited against the purchase price for binding orders placed 
by  a  buyer  participating  in  the  COVAX  Facility.  As  of  December  31,  2023,  the remaining  Gavi  Advance 
Payment Amount of $696.4 million, pending resolution of the dispute with Gavi related to a return of the 
remaining Advance Payment Amount, was reclassified from Deferred revenue to Other current liabilities on 
our  consolidated  balance  sheet.  On  January  24,  2023,  Gavi  filed  a  demand  for  arbitration  with  the 
International  Court  of  Arbitration  based  on  the  claims  described  above.  We  filed  our  Answer  and 
Counterclaims on March 2, 2023. On April 5, 2023, Gavi filed its Reply to our Counterclaims. On February 16, 
2024,  we  and  Gavi  entered  into  a  Termination  and  Settlement  Agreement  (the  “Gavi  Settlement 
Agreement”) terminating the Gavi APA, settling the arbitration proceedings, and releasing both parties of 
all claims arising from, under or otherwise in connection with the Gavi APA. Pursuant to the Gavi Settlement 
Agreement, we are responsible for payment to Gavi of (i) an initial settlement payment of $75 million, which 
we paid on February 20, 2024, and (ii) deferred payments, in equal annual amounts of $80 million payable 
each calendar year through a deferred payment term ending December 31, 2028. The deferred payments 
are due in variable quarterly installments beginning in the first quarter of 2024 and total $400 million during 
the deferred payment term. Such deferred payments may be reduced through Gavi’s use of an annual 
vaccine credit equivalent to the unpaid balance of such deferred payments each year, which may be 
applied to qualifying sales of any of our vaccines funded by Gavi for supply to certain low-income and 
lower-middle income countries. We have the right to price the vaccines offered to such low-income and 
lower-middle income countries at our discretion, and, when utilized by Gavi, we will credit the actual price 
per vaccine paid against the applicable credit. We intend to price vaccines offered via the tender process, 
consistent with our shared goal with Gavi to provide equitable access to those countries. Also in the Gavi 
Settlement Agreement, we grant Gavi an additional credit of up to $225 million, which may be applied 
against  any  additional  qualifying  sales,  exceeding  the  $80  million  deferred  payment  amount  in  any 
calendar year, of our vaccines in such countries during such deferred payment term. In addition, we and 
Gavi entered into a security agreement pursuant to which we granted Gavi a security interest in accounts 
receivable from SIIPL under the SIIPL R21 Agreement (see Note 4 to our consolidated financial statements 
for more details on SIIPL R21 Agreement), which will continue for the deferred payment term of the Gavi 
Settlement Agreement. On February 22, 2024, the claims and counterclaims were dismissed with prejudice. 

Our funding agreements currently include funding from CEPI in the form of one or more forgivable no 
interest term loans (“CEPI Forgivable Loan Funding”). Payments received under the CEPI Forgivable Loan 
Funding  are  only  repayable  if  project  vaccine,  as  defined  under  the  CEPI  funding  agreement, 
manufactured by the CMO network funded by CEPI is sold to one or more third parties (which could include 
sales credited under the Gavi Settlement Agreement), and such sales cover our costs of manufacturing 
such  vaccine,  not  including  manufacturing  costs  funded  by  CEPI.  The  timing  and  amount  of  any  loan 
repayments is currently uncertain.

We  continue  to  assess  our  manufacturing  needs  and  modify  our  global  manufacturing  footprint 
consistent with our contractual obligations to supply, and anticipated demand for, COVID-19 Vaccine, and 
in  doing  so  recognize  that  significant  costs  may  be  incurred.  For  the  2023-2024  vaccination  season,  we 
depend exclusively on SIIPL and SLS for co-formulation and filling (other than in Europe), and PCI Pharma 
Services for finishing COVID-19 Vaccine in Europe. For the 2024-2025 vaccination season, we are seeking to 
expand  our  supply  chain  network  and  introduce  new  single-dose  vial  or  pre-filled  syringe  product 
presentations in certain markets. Any delays or disruptions in these suppliers’ operations could prevent or 
delay the delivery of customer orders. 

As of December 31, 2023, we had $583.8 million in cash and cash equivalents and restricted cash 

as compared to $1.3 billion as of December 31, 2022.  

We funded our operations in 2023 primarily 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 USG Agreement that support 
our  COVID-19  Vaccine  development  activities.  In  May  2023,  we  announced  our  plan  to  restructure  our 
global footprint to reduce our planned expenditures and in January 2024, we announced further reductions 
in  our  global  workforce.  We  anticipate  our  future  operations  to  be  funded  primarily  by  revenue  from 
product  sales,  our  cash  and  cash  equivalents,  and  other  potential  funding  sources  including  equity 
financings,  which  may  include  at  the  market  offerings  under  our  August  2023  Sales  Agreement,  debt 
financings,  collaborations,  strategic  alliances,  asset  sales,  and  marketing,  distribution  or  licensing 
arrangements.

Net  cash  used  in  operating  activities  was  $714.0  million  for  2023,  as  compared  to  cash  used  in 
operating activities of $415.9 million in 2022. The increase in cash used in operating activities is primarily due 
to the timing of payments to vendors and cash receipts from customers, primarily APAs.  

Net cash used in investing activities was $58.8 million for 2023, as compared to $93.0 million in 2022. 
The decrease in cash used in investing activities is primarily due to lower expenditures on equipment and 
leasehold  improvements.  Capital  expenditures  for  the  years  ended  December  31,  2023  and  2022  were 
$53.8 million and $89.1 million, respectively. 

Net cash provided by financing activities was $4.5 million for 2023, as compared to $325.0 million in 
2022. The decrease in cash provided by financing activities is primarily due to the repayment of our 3.75% 
Convertible  notes  of  $325.0  million  in  2023  as  compared  to  gross  proceeds  of  $175.3  million  through  the 
issuance  of  our  2027  Notes  in  2022,  partially  offset  by  an  increase  in  net  proceeds  from  the  sales  of  our 
common stock under our June 2021 and August 2023 Sales Agreements and the Private Placement with SK 
in 2023.  

Going Concern

Supplementary  Data,”  of  this  Annual  Report  on  Form  10-K  have  been  prepared  assuming  that  we  will 
continue as a going concern within one year after the date that the financial statements are issued and 
contemplates the realization of assets and satisfaction of liabilities in the ordinary course of business. The 
consolidated  financial  statements  do  not  include  any  adjustments  relating  to  the  recoverability  and 
classification of recorded asset amounts or the amounts and classification of liabilities that might result from 
the outcome of the uncertainty described below. At December 31, 2023, we had $568.5 million in cash and 
cash equivalents and had a working capital deficiency. During 2023, we incurred a net loss of $545.1 million 
and had net cash flows used in operating activities of $714.0 million. 

In accordance with ASC Topic 205-40, Presentation of Financial Statements - Going Concern, we 
evaluated whether there are conditions and events, considered in the aggregate, that raise substantial 
doubt  about  our  ability  to  continue  as  a  going  concern  within  one  year  after  the  date  that  these 
consolidated financial statements are issued. While our current cash flow forecast for the one-year going 
concern look forward period estimates that we  have sufficient capital available to fund operations, this 
forecast is subject to significant uncertainty, including as it relates to revenue for the next twelve months 
and  our  ability  to  execute  on  certain  cost-reduction  initiatives.  Our  revenue  projections  depend  on  our 
ability to successfully develop, manufacture, distribute, or market our COVID-19 Vaccine for the 2024-2025 
vaccination season, which is inherently uncertain and subject to a number of risks, including our ability to 
obtain regulatory authorizations, introduce a single-dose vial or pre-filled syringe product presentation for 
the  U.S.  commercial  and  certain  other  markets,  the  incidence  of  COVID-19  during  the  2024-2025 
vaccination season, our ability to timely deliver doses and commercial adoption and market acceptance 
of our updated vaccine.  

Further,  failure  to  meet  regulatory  milestones  or  achieve  product  volume  or  delivery  timing 
obligations  under  our  advance  purchase  agreements  may  require  us  to  refund  portions  of  upfront  and 
other payments or result in reduced future payments which could adversely affect our ability to continue 
as a going concern.  

Management  believes  that,  given  our  history  of  recurring  losses,  negative  working  capital  and 
accumulated deficit, conditions or events exist that raise substantial doubt about our ability to continue as 
a going concern through one year from the date that these financial statements are issued. Our plans to 
alleviate  the  conditions  that  exist  include  restructuring  and  cost  reduction  measures  and  successful 
execution of its commercial plans.  

In May 2023, we announced our Restructuring Plan, which includes a more focused investment in 
our  COVID-19  Vaccine,  reduction  to  our  pipeline  spending,  the  continued  rationalization  of  our 
manufacturing network, a reduction to our global workforce, as well as the consolidation of facilities, and 
infrastructure. In our May 2023 announcement, the workforce reduction plan included an approximately 
25% reduction in the Company’s global workforce, comprised of an approximately 20% reduction in full-
time Company employees and the remainder comprised of contractors and consultants. We incurred one 
time restructuring expenses of $14.6 million during the twelve months ended December 31, 2023. See Note 
17  to  our  consolidated  financial  statements  for  more  details  on  restructuring.  We  expect  the  full  annual 
impact  of  the  cost  savings  to  be  realized  in  2024  due  to  timing  of  implementing the  measures,  and  the 
applicable laws, regulations, and other factors in the jurisdictions in which we operate.  

In  November  2023,  we  announced  that  we  anticipated  further  reducing  our  research  and 
development and selling, general and administrative expenses and our supply network costs. We intend to 
prioritize  improvements  to  our  long-term  supply  chain  efficiency.  In  January  2024,  as  part  of  reducing 
combined research and development and selling. general and administrative expenses, we announced 
an approximately 12% reduction of our global workforce, comprised of an approximately 9% reduction in 
our full-time employees and the remainder comprised of contractors and consultants. We expect the full 
annual  impact  of  the  cost  savings  to  be realized  in  2025  and approximately  85%  of  the  annual  impact, 
excluding one-time charges, to be realized in 2024 due to the timing of implementing the measures and 
the applicable laws,  regulations  and other  factors  in  the  jurisdictions  in  which  it  operates.  We  expect  to 
record a charge of approximately $4 million to $7 million related to one-time employee severance and 
benefit costs, the majority of which is expected to be incurred in the first quarter of 2024. Upon completion, 

93

 
 
 
 
 
 
 
our  resulting  workforce  is  expected  to  be  approximately  30%  lower  as  compared  to  the  end  of  the  first 
quarter of 2023. 

Our plans may include raising additional capital through a combination of equity financings, which 
may  include  at  the  market  offerings  under  our  August  2023  Sales  Agreement,  debt  financings, 
collaborations, strategic alliances, asset sales and marketing, distribution, or licensing arrangements. New 
financings may not be available to us on commercially acceptable terms, or at all. Also, any collaborations, 
strategic alliances, asset sales and marketing, distribution, or licensing arrangements may require us to give 
up some or all of our rights to a product or technology, which in some cases may be at less than the full 
potential  value  of  such  rights.  If  we  are  unable  to  obtain  additional  capital,  we  will  assess  our  capital 
resources and may be required to delay, reduce the scope of, or eliminate some or all of our operations, 
or further downsize our organization, any of which may have a material adverse effect on our business, 
financial condition, results of operations, and ability to operate as a going concern. 

Due to the uncertainties associated with our plans, there is substantial doubt about our ability to 
continue as a going concern for at least one year from the date that these financial statements are issued.

(1)  In 2022, we issued $175.3 million of 5.00% convertible senior unsecured notes due in 2027. See “Note 10—
Long-term Debt” included in our Notes to Consolidated Financial Statements for additional information 
related to our convertible notes. 

(2)  Purchase  commitments  primarily  represent  our  non-cancelable  fixed  payment  obligations  under 
certain  CMO,  CDMO,  and  laboratory  supply  agreements  that  we  are  not  contractually  able  to 
terminate  for  convenience.  Certain  agreements  provide  for  termination  rights  subject  to  termination 
fees. Under such agreements, we are contractually obligated to make payments to vendors, mainly to 
reimburse them for their estimated unrecoverable expenses incurred. As of December 31, 2023, these 
agreements  are  active  ongoing  arrangements  and  we  expect  to  receive  value  from  these 
arrangements in the future. The amount of such obligations is dependent on the timing of termination 
and the terms of the relevant agreement, and cannot be reasonably estimated. Our current obligations 
under non-cancelable purchase agreements are reflected on our consolidated balance sheets. 

In  addition  to  the  above  obligations,  we  enter  into  a  variety  of  agreements  and  financial 
commitments  in  the  normal  course  of  business.  The  terms  generally  allow  us  the  option  to  cancel, 
reschedule,  or  adjust  our  requirements  based  on  our  business  needs,  prior  to  the  delivery  of  goods  or 
performance of services. It is not possible to predict the maximum potential amount of future payments 
under  these  agreements  due  to  the  conditional  nature  of  our  obligations  and  the  unique  facts  and 
circumstances involved in each particular agreement. 

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.  our  results  of  operations,  including  our  foreign 
subsidiaries’ operations, are subject to foreign currency exchange rate fluctuations, primarily the U.S. dollar 
against the Euro, Pound Sterling, Swedish Krona, and Czech Koruna. This exchange exposure may have a 
material effect on our cash and cash equivalents, cash flows, and results of operations, particularly in cases 
of revenue generated under APAs that include provisions that impact our and our counterparty’s currency 
exchange exposure. To date, we have not entered into any foreign currency hedging contracts, although 
we may do so in the future. 

We  also  face  foreign  currency  exchange  exposure  that  arises  from  translating  the  results  of  our 
global  operations  to  the  U.S.  dollar  at  exchange  rates  that  have  fluctuated  from  the  beginning  of  the 
period. While the financial results of our global activities are reported in U.S. dollars, the functional currency 
for our foreign subsidiaries is generally their respective local currency. Fluctuations in the foreign currency 
exchange rates of the countries in which we do business will affect our operating results, often in ways that 
are difficult to predict. A 10% decline in the foreign exchange rates (primarily against the U.S. dollar) relating 
to our foreign subsidiaries would result in a decline of stockholders’ equity (deficit) of approximately $52 
million as of December 31, 2023. 

Market and Interest Rate Risk 

The  primary  objective  of  our  investment  activities  is  preservation  of  capital,  with  the  secondary 

objective of maximizing income. 

Our exposure to interest rate risk is primarily confined to our investment portfolio. 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. 

Our  convertible  senior  unsecured  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.

Item 9A.  CONTROLS AND PROCEDURES 

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 

95

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Securities  and  Exchange  Commission.  “Disclosure  controls  and  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 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 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 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. 

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,  2023.  In  making  this  assessment,  our  management  used  the  criteria  set  forth  in  the  2013 
Internal  Control-Integrated  Framework  issued  by  the  Committee  of  Sponsoring  Organizations  of  the 
Treadway Commission. Based on its assessment, our management has determined that, as of December 
31, 2023, our internal controls over financial reporting are effective based on those criteria. 

Ernst & Young LLP has issued a report on our internal control over financial reporting. This report is 

included in the Reports of Independent Registered Public Accounting Firm in Item 15(a)(1). 

Changes in Internal Control over Financial Reporting 

Our management, including our chief executive officer and chief financial officer, has evaluated 
any changes in our internal control over financial reporting that occurred during the year ended December 
31, 2023 and has concluded that there was no change that occurred during the year ended December 
31, 2023 that materially affected, or is reasonably likely to materially affect, our internal control over financial 
reporting.

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, 2023 and 2022, 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, 
2023, 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, 2023 and 2022, and the results of its operations and its cash flows for each of the three years in 
the period ended December 31, 2023, 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, 2023, 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 February 28, 2024 expressed 
an unqualified opinion thereon. 

The Company’s Ability to Continue as a Going Concern 

The  accompanying  consolidated  financial  statements  have  been  prepared  assuming  that  the  Company  will 
continue  as  a  going  concern.  As  discussed  in  Note  2  to  the  financial  statements,  the  Company  has  suffered 
recurring losses, has negative working capital, and an accumulated deficit and has stated that substantial doubt 
exists about the Company’s ability to continue as a going concern. Management’s evaluation of the events and 
conditions  and management’s  plans  regarding  these  matters  are  also described in  Note  2.  The  consolidated 
financial statements do not include any adjustments that might result from the outcome of this uncertainty. 

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 do 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 matter or on 
the account or disclosures to which they relate.

Description of 
the Matter 

How We 
Addressed the 
Matter in Our 
Audit 

Description of 
the Matter 

Inventory Excess and Obsolescence Reserve 
As of December 31, 2023, the Company had $41.7 million of inventory. As disclosed in Note 2, 
inventories  are  stated  at  the  lower  of  cost  or  net  realizable  value.  The  Company  assesses  its 
inventory levels each reporting period and writes down inventory that is either expected to be at 
risk of expiration prior to sale, or for which there are inventory quantities in excess of expected 
requirements. For the year ended December 31, 2023, inventory write-downs were $72.4 million 
and  losses  on  firm  purchase  commitments  were  $73.5  million.  In  addition,  for  the  year  ended 
December 31, 2023, the Company recorded recoveries on firm purchase commitments of $40.2 
million  related  primarily  to  negotiated  reductions  to  previously  recognized  firm  purchase 
commitments. 

Auditing management's estimates for excess and obsolete inventory involved subjective auditor 
judgment because the estimates rely on a number of factors that are affected by market and 
economic  conditions  outside  the  Company's  control.  In  particular,  the  obsolete  and  excess 
inventory calculations are sensitive to significant assumptions, including the expected demand 
for the Company’s products, assumptions about the vaccine’s life cycle, the effect on demand 
of competitive products and the Company's purchase commitments. 

We obtained an understanding, evaluated the design, and tested the operating effectiveness of 
internal  controls  over  the  Company's  excess  and  obsolete  inventory  reserve  process  including 
management’s  review  of  the  significant  assumptions  described  above  and  controls  over  the 
completeness and accuracy of the information used to develop the estimate. 

Our  substantive  audit  procedures 
included,  among  others,  evaluating  methodologies, 
assumptions and data utilized in the analysis for inventory expected to be at risk for expiration or 
excess. We evaluated and compared forecasted demand to historical trends, compared actual 
inventory  levels  to  forecasted  demand  requirements  and  evaluated  the  sensitivity  of  sales 
forecast assumptions on the amount of inventory reserves recorded. 

Product Return Reserve Estimate- U.S. Commercial Sales 
As  of  December  31,  2023,  the  Company  recorded  a  liability  for  product  returns  related  to  US 
commercial sales of $82.5 million. As disclosed in Note 2, the Company offers U.S. commercial 
customers  the  right  to  return  its  product.  These  return  rights  include  the  right  of  wholesale 
distributors to return unsold and expired doses and indirect customers the right to return any partial 
or unused vials upon expiry. The Company estimates variable consideration resulting from these 
product  returns  based on quantitative  and qualitative  data  from  various  internal  and external 
sources. 

Auditing  management’s  estimate  of  product  returns  was  complex  and  judgmental  given  the 
Company’s  limited  history  of  US  commercial  sales,  and  management  considers  the  level  of 
inventory in the distribution channel, projected market demand, utilization data, returns claims 
received, and product shelf life. 

How We 
Addressed the 
Matter in Our 
Audit 

We obtained an understanding, evaluated the design, and tested the operating effectiveness of 
internal  controls  over  the  product  return  reserve  estimation  process  for  U.S.  commercial  sales, 
including management’s review of the level of inventory in the distribution channel, as well as 
inputs and assumptions used to develop the estimate of the product returns reserve. 

Our  substantive  audit  procedures  included,  among  others,  testing  the  level  of  product  in  the 
channel held by a sample of wholesale distributors at December 31, 2023. For indirect customers, 
we  obtained  and  reviewed  the  Company’s  estimated  channel  mix,  and  compared  relevant 
inputs  to  underlying  actual  sales  data.  In  addition,  we  assessed  management’s  estimate  of 
projected market demand for the product through the expiration dates, by analyzing available 
internal and third party utilization data for the product for the current vaccination season, and 
we also assessed management’s estimate of total U.S. commercial market size for the season by 
analyzing available third party data. We also evaluated the sensitivities of changes in projected 
demand on the product return reserve estimate recorded.

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, 2023, 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,  2023, 
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, 2023 and 2022, 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, 2023, and the related notes and our report 
dated February 28, 2024 expressed an unqualified opinion that included an explanatory paragraph regarding the 
Company’s ability to continue as a going concern. 

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.

NOVAVAX, INC. 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 

Note 1 – Organization & Business 

Novavax,  Inc.  (“Novavax,”  and together  with  its  wholly  owned subsidiaries,  the “Company”)  is  a 
biotechnology company that promotes improved health by discovering, developing, and commercializing 
innovative vaccines to prevent serious infectious diseases. Novavax offers a differentiated vaccine platform 
that  combines  a  recombinant  protein  approach,  innovative  nanoparticle  technology  and  patented 
Matrix-M™ adjuvant to enhance the immune response. Novavax currently has one commercial program, 
for  vaccines  to  prevent  COVID-19,  which  includes  Nuvaxovid™  prototype  COVID-19  vaccine  ("NVX-
CoV2373,”  or  “prototype  vaccine”)  and  Nuvaxovid™  updated  COVID-19  vaccine  (“NVX-CoV2601,”  or 
“updated vaccine”) (collectively, “COVID-19 Vaccine”). Local regulatory authorities have also specified 
nomenclature  for  the  prototype  and updated  vaccines  within  their  territories  (e.g.,  “Novavax  COVID-19 
Vaccine,  Adjuvanted”  and  “Novavax  COVID-19,  Adjuvanted  (2023-2024  Formula)”,  respectively,  for  the 
U.S.).  The  Company’s  partner,  Serum  Institute  of  India  Pvt.  Ltd.  (“SIIPL”),  markets  NVX-CoV2373  as 
“Covovax™.”  

Beginning  in  2022,  the  Company  received  approval,  interim  authorization,  provisional  approval, 
conditional  marketing  authorization,  and  emergency  use  authorization  (“EUA”)  from  multiple  regulatory 
authorities globally for its prototype vaccine for both adult and adolescent populations as a primary series 
and for both homologous and heterologous booster indications in select territories. In October 2023, the 
U.S. Food and Drug Administration (“U.S. FDA”) amended the EUA for its prototype vaccine to include its 
updated vaccine. The amended EUA authorizes use of the Company’s updated vaccine in individuals 12 
years and older. In October 2023, the European Commission (“EC”) granted approval for the Company’s 
updated vaccine for active immunization to prevent COVID-19 caused by SARS-CoV-2 in individuals aged 
12  and  older.  Currently,  the  Company  significantly  depends  on  its  supply  agreement  with  SIIPL  and  its 
subsidiary, Serum Life Sciences Limited (“SLS”), for co-formulation, filling and finishing (other than in Europe) 
and on its service agreement with PCI Pharma Services for finishing in Europe.  

Novavax is advancing development of other vaccine candidates, including its COVID19-Influenza 
Combination (“CIC”) vaccine candidate and additional vaccine candidates. The Company’s COVID-19 
Vaccine and its other vaccine candidates incorporate the Company’s proprietary Matrix-M™ adjuvant to 
enhance the immune response and stimulate higher levels of functional antibodies and induce a cellular 
immune response. 

Note 2 – Summary of Significant Accounting Policies 

Basis of Presentation 

The consolidated financial statements include the accounts of Novavax, Inc. and its wholly owned 

subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. 

Liquidity and Going Concern 

The  accompanying  consolidated  financial  statements  have  been  prepared  assuming  that  the 
Company will continue as a going concern within one year after the date that the financial statements are 
issued  and  contemplates  the  realization  of  assets  and  satisfaction  of  liabilities  in  the  ordinary  course  of 
business.  The  consolidated  financial  statements  do  not  include  any  adjustments  relating  to  the 
recoverability and classification of recorded asset amounts or the amounts and classification of liabilities 
that might result from the outcome of the uncertainty described below.  

As of December 31, 2023, the Company had $568.5 million in cash and cash equivalents and had 
a  working  capital  deficiency.  In  January  2024,  pursuant  to  the  June  2023  Amendment  to  the  advance 
purchase agreement between the Company and the Canadian government (the “Canada APA”), the 
Company  received  the  second  installment  of  $174.8  million  from  the  Canadian  government  that  was 

F-9 

 
 
 
 
 
 
 
 
 
 
contingent  and  payable  upon  the  Company’s  delivery  of  vaccine  doses  (see  Note  3).  During  the  year 
ended December 31, 2023, the Company incurred a net loss of $545.1 million and had net cash flows used 
in operating activities of $714.0 million. 

In  accordance  with  Accounting  Standards  Codification  (“ASC”)  Topic  205-40,  Presentation  of 
Financial Statements - Going Concern, the Company evaluated whether there are conditions and events, 
considered in the aggregate, that raise substantial doubt about its ability to continue as a going concern 
within  one  year  after  the  date  that  these  consolidated  financial  statements  are  issued.  While  the 
Company’s current cash flow forecast for the one-year going concern look forward period estimates that 
there will be sufficient capital available to fund operations, this forecast is subject to significant uncertainty, 
including as it relates to revenue for the next 12 months and the Company’s ability to execute on certain 
cost-reduction initiatives. The Company’s revenue projections depend on its ability to successfully develop, 
manufacture,  distribute  and market  its  updated  vaccine for  the  2024-2025  vaccination season,  which  is 
inherently uncertain and subject to a number of risks, including the Company’s ability to obtain regulatory 
authorizations,  introduce  a  single-dose  vial  or  pre-filled  syringe    product  presentation  for  the  U.S. 
commercial  and  certain  other  markets,  the  incidence  of  COVID-19  during  the  2024-2025  vaccination 
season,  the  Company’s  ability  to  timely  deliver  doses  and  achieve  commercial  adoption  and  market 
acceptance of its updated vaccine.  

Failure to meet regulatory milestones or achieve product volume or delivery timing obligations under 
the Company’s advance purchase agreements (“APAs”) may require the Company to refund portions of 
upfront  and  other  payments  or  result  in  reduced  future  payments  which  would  adversely  affect  the 
Company’s ability to continue as a going concern.  

Management  believes  that,  given  the  history  of  recurring  losses,  negative  working  capital  and 
accumulated deficit, conditions or events exist that raise substantial doubt about the Company’s ability to 
continue as a going concern through one year from the date that these financial statements are issued. 
Management’s  plans  to  alleviate  the  conditions  that  exist  include  restructuring  and  cost  reduction 
measures and successful execution of its commercial plans.  

In  May  2023,  the  Company  announced  a  global  restructuring  and  cost  reduction  plan  (the 
“Restructuring Plan”), which includes a more focused investment in its COVID-19 Vaccine, reduction to its 
pipeline  spending,  the  continued  rationalization  of  its  manufacturing  network,  a  reduction  to  the 
Company’s global workforce, as well as the consolidation of facilities, and infrastructure. In January 2024, 
as  part  of  reducing  combined  research  and  development  and  selling,  general  and  administrative 
expenses, the Company announced further reductions in its global workforce (the “2024 Cost Reduction 
Plan”)  (see  Note  18).  The  Company  intends  to  prioritize  improvements  to  its  long-term  supply  chain 
efficiency. The Company expects the full annual impact of the Restructuring Plan to be realized in 2024 and 
the full annual impact of the 2024 Cost Reduction Plan to be realized in 2025 and approximately 85% of the 
annual impact, excluding one-time charges, to be realized in 2024. During the year ended December 31, 
2023, the Company recorded a charge of $4.5 million related to one-time employee severance and benefit 
costs  and  recorded  an  impairment  charge  of  $10.1  million  related  to  the  consolidation  of  facilities  and 
infrastructure (see Note 17) and expects to record an additional charge of approximately $4 million to $7 
million related to one-time employee severance and benefit costs, the majority of which is expected to be 
incurred in the first quarter of 2024.  

Management’s plans may also include raising additional capital through a combination of equity 
and debt financing, collaborations, strategic alliances, asset sales, and marketing, distribution, or licensing 
arrangements. New financings may not be available to the Company on commercially acceptable terms, 
or  at  all.  Also,  any  collaborations,  strategic  alliances,  asset  sales  and  marketing,  distribution,  or  licensing 
arrangements may require the Company to give up some or all of its rights to a product or technology, 
which in some cases may be at less than the full potential value of such rights. If the Company is unable to 
obtain  additional  capital,  the  Company  will  assess  its  capital  resources  and  may  be  required  to  delay, 
reduce the scope of, or eliminate some or all of its operations, or further downsize its organization, any of 
which may have a material adverse effect on its business, financial condition, results of operations, and 
ability to operate as a going concern. 

F-10 

 
 
 
 
 
 
Due to the uncertainties associated with management’s plans, there is substantial doubt about the 
Company’s ability to continue as a going concern for at least one year from the date that these financial 
statements are issued. 

Use of Estimates 

The  preparation  of  the  consolidated  financial  statements  in  conformity  with  generally  accepted 
accounting  principles  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.  

Revenue Recognition 

At  contract  inception,  the  Company  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  ASC  Topic  606,  Revenue  from  Contracts  with  Customers  (“ASC 
606”), or are contributions subject to the guidance in ASC Topic 958-605, Not-for-Profit Entities – Revenue 
Recognition (“ASC 958-605”). The Company recognizes revenue from 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 obligation(s) in the contract; and (v) recognize revenue when (or as) it satisfies a 
performance  obligation.  The  Company  only  recognizes  revenue  under  the  five-step  model  when  it  is 
probable that it will collect the consideration it is entitled to in exchange for the goods or services it transfers 
to its customer. The Company recognizes contribution revenue within the scope of ASC 958-605 when the 
funder-imposed conditions have been substantially met. Contributions are recorded as deferred revenue 
until the period in which research and development activities are performed that satisfy the funder-imposed 
conditions. 

Product Sales - Advance Purchase Agreements  

Product  sales  include  sales  associated  with  COVID-19  Vaccine  supply  agreements,  sometimes 
referred  to  as  APAs,  with  various  international  governments.  The  Company  recognizes  revenue  from 
product sales related to these APA’s based on the transaction price per dose calculated in accordance 
with  ASC  606  at  the  point  in  time  when  control  of  the  product  transfers  to  the  customer  and  customer 
acceptance has occurred, unless such acceptance provisions are deemed perfunctory. The APAs typically 
contain  terms  that  include  upfront  payments  which  are  reflected  in  Deferred  revenue.  The  Company 
constrains the transaction price for APA’s until it is probable that a significant reversal in revenue recognized 
will not occur. Specifically, if an APA includes a provision whereby the customer may request a discount, 
return, or refund, or includes a term that may have the effect of decreasing the price per dose of previously 
delivered shipments, revenue is constrained based on an estimate of the impact of the transaction price 
until it is probable that a significant reversal in revenue recognized will not occur.  

Product Sales - U.S. Commercial  

In  the  fourth  quarter  of  2023,  the  Company  commenced  sales  of  COVID-19  Vaccine  to  the  U.S. 
commercial market. Product sales in the U.S. are primarily made through large pharmaceutical wholesale 
distributors at the wholesale acquisition cost (“WAC”). The Company recognizes revenue upon title transfer 
(which is typically at time of delivery), provided all other revenue recognition criteria have been met. The 
transaction  price  includes  estimates  of  variable  consideration  for  which  reserves  are  established  that 
primarily result from invoice discounts for prompt payment, wholesale distributor fees, chargebacks, and 
product returns (collectively, “gross-to-net deductions”). These estimates are based on the amounts earned 
or to be claimed for related sales and are classified as either reductions of gross accounts receivable or a 
current liability based on the nature of the estimate, the expected settlement method, and net position by 
individual customer. Where appropriate, these estimates are based on factors such as industry data and 
forecasted customer buying and payment patterns, the Company’s experience, current contractual and 

F-11 

 
 
 
 
 
 
 
 
statutory requirements, specific known market events, and trends. Variable consideration is included in the 
transaction price only to the extent that it is probable that a significant reversal in the amount of cumulative 
revenue  recognized  will  not  occur  when  the  uncertainty  associated  with  the  variable  consideration  is 
subsequently resolved. If actual results vary from estimates, the Company will adjust the estimates, which 
would affect product sales in the period such variances become known.  

Gross-to-net deductions include the following: 

•  Wholesale  distributor  fees,  discounts,  and  chargebacks:  The  Company  has  arrangements  under 
which indirect customers such as retailers, healthcare providers, and others receive discounts to the 
WAC. The chargeback represents the difference between the WAC and this negotiated discounted 
price.  For  distribution  and  related  services,  the  Company  incurs  service  fees  to  its  wholesale 
distributors.  In  addition,  the  Company  typically  offers  wholesale  distributor  customers  invoice 
discounts on product sales for prompt payments. The Company estimates chargebacks, discounts, 
and fees it will owe and deducts these amounts from gross product sales at the time the revenue is 
recognized  based  on  the  contractual  terms  and  the  Company’s  expectations  regarding  future 
customer behaviors.  

•  Product  returns:  The  Company  offers  U.S.  customers  the  right  to  return  COVID-19  Vaccine.  These 
return rights include the right of wholesale distributors to return unsold and expired doses and the 
right  of  indirect  customers  to  return  any  partial  or  unused  vials  upon  expiry.  Estimated  returns  for 
COVID-19  Vaccine  are  determined  considering  levels  of  inventory  in  the  distribution  channel, 
projected  market  demand,  utilization  data,  returns  claims  received,  and  product  shelf  life.  The 
estimated amount for product returns is deducted from gross product sales in the period the related 
product sales are recognized. 

•  Other: Fees payable to retailers, healthcare providers, and buying groups, including certain patient 
assistance programs, are deducted from gross product sales in the period the related product sales 
are recognized. 

Grants 

Grant  revenue includes both revenue from government contracts and grants from organizations 
such as the Coalition for Epidemic Preparedness Innovations (“CEPI”). The Company performs research and 
development  under  government  funding,  grant,  license,  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 COVID-19 Vaccine. 

Under  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  COVID-19  Vaccine  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 for these contracts over 
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  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 

F-12 

 
 
 
 
 
and fee recognition on the Company’s 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  the 
Company  and  the  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 
underlying  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,  including  the  CEPI  arrangement,  the  Company  is 
primarily  entitled  to  reimbursement  for  costs  that  support  development  related  activities  of  COVID-19 
Vaccine.  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 under the grant funding arrangements are considered conditional contributions under the scope 
of  ASC  958-605  and  are  recorded  as  deferred  revenue  until  the  period  in  which  such  research  and 
development activities are actually performed in a manner that satisfies the funder-imposed conditions. 
Payments  received  under  the  CEPI  Forgivable  Loan  Funding  are  only  repayable  if  project  vaccine,  as 
defined under the CEPI funding agreement, manufactured by the contract manufacturing organization 
(“CMO”) network funded by CEPI is sold to one or more third parties (which could include sales credited 
under the Gavi Settlement Agreement), and such sales cover the Company’s costs of manufacturing such 
vaccine,  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 Topic 730, Research and Development (“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 has determined that payments received under these agreements should be recorded as 
revenue  under  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, the Company considered a number of factors, including whether it is principal under the 
arrangement, and whether the arrangement is significant to, and part of, the Company’s core operations. 
The Company will record revenue as it performs the contractual research and development services. 

Payments received in advance related to arrangements where revenue is recognized under ASC 
958-605 that are related to future performance are deferred and recognized as revenue when the research 
and  development  activities  are  performed.  Such  cash  payments  are  restricted  as  to  their  use  and  are 
reflected in Restricted cash until expenditures contemplated in the funding agreements are incurred. 

Royalties and Other 

The  Company  also  has  various  arrangements  that  include  a  right  for  a  customer  to  use  the 
Company's intellectual property as a functional license, where the Company’s performance obligation is 
satisfied at the point in time at which the license is granted. These licensing arrangements include sales-
based royalties,  certain development  and commercial  milestone  payments,  and the  sale  of  proprietary 

F-13 

 
 
 
 
Matrix-MTM adjuvant. Because development milestone payments are contingent on the achievement of 
milestones,  such  as  regulatory  approvals,  that  are  not  within  the  Company  or  licensee's  control,  the 
payments are not considered probable of being achieved and are excluded from the transaction price 
until the milestone is achieved, at which point the Company recognizes revenue. For arrangements that 
include sales-based royalties related to a previously granted license, including milestone payments based 
upon  the  achievement  of  a  certain  level  of  product  sales,  the  license  is  deemed  to  be  the  sole  or 
predominant item to which the royalties relate and the Company recognizes revenue when the related 
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. 

Cost of Sales 

Cost  of  sales  includes  cost  of  raw  materials,  production,  and  manufacturing  overhead  costs 
associated with the Company’s product sales during the period. Cost of sales also includes adjustments for 
excess,  obsolete,  or  expired  inventory;  idle  capacity;  and  losses  on  firm  purchase  commitments  to  the 
extent the cost cannot be recovered based on estimates about future demand. Cost of sales does not 
include  certain  expenses  related  to  raw  materials,  production,  and  manufacturing  overhead  costs  that 
were expensed prior to regulatory authorization as described under the caption “Inventory.” 

Research and Development Expenses 

Research  and  development  expenses  include  salaries;  stock-based  compensation;  laboratory 
supplies;  consultants  and  subcontractors,  including  external  contract  research  organizations  (“CROs”), 
CMOs,  and  contract  development  and  manufacturing  organizations  (“CDMOs”);  and  other  expenses 
associated  with  the  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 CRO, CMO, and 
CDMO 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 
used to estimate these accruals. 

Advertising Costs 

Advertising  costs  are  expensed  as  incurred.  The  Company  had  advertising  costs  of  $91.5  million, 

$84.0 million and $8.9 million during the years ended December 31, 2023, 2022 and 2021, respectively. 

Stock-Based Compensation 

The  Company  accounts  for  stock-based  compensation  related  to  grants  of  stock  options,  stock 
appreciation rights (“SARs”), and restricted stock awards (“RSUs”), and purchases under the Company’s 
Employee  Stock  Purchase  Plan  (“ESPP”),  at  fair value.  The  Company  recognizes  compensation expense 

F-14 

 
 
 
 
 
 
 
 
 
 
 
 
related to such awards on a straight-line basis over the requisite service period (generally the vesting period) 
of  the  equity  awards,  based  on  the  award's  fair  value  at  the  grant  date.  The  requisite  service  period  is 
typically one to four years. Forfeitures for all awards are recognized as incurred. The Company generally 
settles stock-based awards with newly issued shares. 

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

Cash and Cash Equivalents 

Cash and cash equivalents consist of highly liquid investments with maturities of three months or less 
from the date of purchase. Cash equivalents are recorded at cost, which approximates fair value due to 
their short-term nature. 

Fair Value Measurements 

The  Company  applies  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 grant 
agreements and cash collateral accounts under letters of credit that serve as security deposits for certain 
facility leases. Payments received under grant agreements become unrestricted as the Company incurs 
expenses for services performed under these agreements. As of December 31, 2023 and 2022, restricted 
cash  balances  (both  current  and  non-current)  consisted  primarily  of  payments  under  the  CEPI  funding 
agreements and letter of credits. 

Accounts Receivable 

The  Company  recognizes  amounts  due  from  customers  as  accounts  receivable  when  its  right  to 
payment is unconditional. Gross-to-net deductions are classified as reductions of gross accounts receivable 
if  settlement  is  expected  to  occur  through  a  reduction  in  the amount  paid  to  Novavax by  its  customer. 
Account receivables are recorded net of any allowance for credit losses. The Company’s estimate for the 
allowance for credit losses, which has not been significant to date, is determined based on the credit risk 
of its customers based on historical loss experience, economic conditions, the aging of receivables, and 
customer-specific risks. 

F-15 

 
 
 
 
 
 
 
 
 
 
 
Concentration of Risk 

Financial instruments expose the Company to concentration of credit risk and consist primarily of 
cash  and  cash  equivalents.  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 that 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. 

The Company's accounts receivable arise from revenue arrangements with customers in different 
countries. The Company's revenue is primarily due to product sales, grants made by government-sponsored 
and private organizations, and royalties from its collaboration and license partners. The following customers 
accounted for more than 10% of total revenue or accounts receivable for the periods presented:

The Company currently depends significantly on one supplier for co-formulation, filling, and finishing 
of COVID-19 Vaccine. The loss of this supplier could prevent or delay the Company’s delivery of customer 
orders. 

Inventory 

Inventory  is  recorded  at  the  lower  of  cost  or  net  realizable  value  under  the  First  In,  First  Out 
methodology, taking into consideration the expiration of the inventory item. The Company determines the 
cost of raw materials using moving average costs and the cost of semi-finished and finished goods using a 
standard  cost  method  adjusted  on  a  periodic  basis  to  reflect  the  deviation  in  the  actual  cost  from  the 
standard  cost  estimate.  Standard  costs  consist  primarily  of  the  cost  of  manufacturing  goods,  including 
direct  materials,  direct  labor,  and  the  services  and  products  of  third-party  suppliers.  Manufacturing 
overhead costs are applied to semi-finished and finished goods based on expected production levels. The 
Company utilizes third-party CMOs, CDMOs, and other suppliers and service organizations to support the 
procurement  and  processing  of  raw  materials,  management  of  inventory,  packaging,  and  the  delivery 
process. Adjustments to reduce the cost of inventory to its net realizable value, if required, are made for 
estimated  excess,  obsolete,  or  expired  inventory  through  cost  of  sales.  At  each  reporting  period,  the 
Company  assesses  whether  there  are  excess  firm,  non-cancelable,  purchase  commitment  liabilities, 
resulting from supply agreements with third-party CMOs and CDMOs. The determination of net realizable 
value of inventory and firm purchase commitment liabilities requires judgment, including consideration of 
many factors, such as estimates of future product demand, current and future market conditions, potential 
product obsolescence, expiration and utilization of raw materials under firm purchase commitments, and 
contractual minimums. 

Prior  to  initial  regulatory  authorization  for  its  product  candidates,  the  Company  expenses  costs 
relating to raw materials, production, and manufacturing overhead costs as research and development 

F-16 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
expenses  in  the  consolidated  statements  of  operations,  in  the  period  incurred.  Subsequent  to  initial 
regulatory authorization for a product candidate, the Company capitalizes the costs of production for a 
particular  supply  chain  as  inventory  when  the  Company  determines  that  it  has  a  present  right  to  the 
economic benefit associated with the product. 

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.  Repairs  and 
maintenance costs are expensed as incurred. The estimated useful lives of property and equipment are 
described below: 

Buildings 
Machinery and equipment 
Computer hardware 

Leasehold improvements

The  Company  enters  into  manufacturing  supply  agreements  with  CMOs  and  CDMOs  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 an embedded 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, 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 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 
lease  period,  the  Company  evaluates  facts  and 
contractual  agreements. 

In  determining  the 

F-17 

 
 
 
 
 
 
 
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 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  from  the  lease  commencement  date  through  the  end  of  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 730 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; the term of a lease embedded in its manufacturing supply agreements; and the 
Company’s incremental borrowing rate, which is determined using estimates such as the estimated value 
of the underlying leased asset and financial profile of comparable companies. 

Impairment of Long-Lived Assets 

Long-lived  assets,  including  property  and  equipment,  internal-use  software,  and  ROU  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.  If  such  events  or 
changes in circumstances occur, the Company assesses the recoverability of the long-lived assets (or asset 
group) by comparing their projected future undiscounted net cash flows over their remaining lives against 
their respective carrying amounts. If the cash flows are not expected to be sufficient to recover the carrying 
amount of the assets (or asset group), they are written down to their estimated fair values. 

Restructuring  

The  Company  recognizes  restructuring  charges  when  such  costs  are  incurred.  The  Company’s 
restructuring  charges  consist  of  employee  severance  and  other  termination  benefits  related  to  the 
reduction  of  its  workforce,  the  consolidation  of  facilities  and  infrastructure  and  other  costs.  Termination 
benefits are expensed on the date the Company notifies the employee, unless the employee must provide 
future  service,  in  which  case the benefits  are  expensed ratably  over  the future  service  period.  Ongoing 
benefits are expensed when restructuring activities are probable and the benefit estimable.  

See Note 17 for additional information on the severance and employee benefit costs for terminated 
employees and impairment of long-lived assets in connection with the Company’s Restructuring Plan and 
Note  18  for  information  on  the  expected  severance  and  employee  benefit  costs  as  a  result  of  the 
Company’s workforce reduction announced on January 31, 2024. 

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  and 
commercialization of innovative vaccines, it operates as a single operating segment and has one reporting 

F-18 

 
 
 
 
 
 
 
 
 
unit. The one-step impairment test, which requires a comparison of the fair value of a reporting unit to its 
carrying value, including goodwill, is required to be applied to all reporting units including reporting units 
with zero or negative carrying value. A reporting unit with a zero or negative carrying value likely will not 
have  an  impairment.  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.  

As of December 31, 2023 and 2022, the Company had a negative carrying value and did not have 

any impairment of goodwill. 

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. 

The Global Intangible Low-Taxed Income (“GILTI”) provisions under the Tax Cuts and Jobs Act of 
2017 impose U.S. tax on certain foreign income in excess of a deemed return on tangible assets of foreign 
corporations. The Company has elected to treat any potential GILTI inclusions as period costs. 

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. 

The  Company  has  historically  generated  significant  federal,  state,  and  foreign  tax  net  operating 
losses,  which  may  be  subject  to  limitation  in  future  periods.  Management  has  fully  reserved  the  related 
deferred tax assets with a valuation allowance in the current reporting period as it is more likely than not 
that the related benefit will not be realized. The Company is currently subject to examination in all open tax 
years. 

Net Loss per Share 

Basic net loss per share is computed by dividing net loss by the weighted-average number of shares 
of common stock outstanding for the period and excludes the effects of any potentially dilutive securities. 
Diluted net loss per share is computed using the treasury stock method 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. As of December 31, 2023, the Company's 2027 Notes (see Note 
10) would have been convertible into approximately 14 million shares of the Company's common stock 
assuming the common stock price is equal to or greater than $12.50. These shares, after giving effect to the 
add back of interest expense and unamortized discounts and debt issuance costs on the Notes and any 
shares  due  to  the  Company  upon  settlement  of  its  capped  call  transactions,  are  excluded  from  the 
computation,  as  their  effect  is  antidilutive  under  the  if-converted  method.  In  addition,  all  stock  options, 
SARs, and unvested RSUs are excluded from the computation as their effect is antidilutive. 

Foreign Currency 

The accompanying consolidated financial statements are presented in U.S. dollars. The functional 
currency  of  the  Company’s  international  subsidiaries  is  generally  the  local  currency.  The  financial 

F-19 

 
 
 
 
 
 
 
 
 
 
statements of international subsidiaries are translated to U.S. dollars using the exchange rate in effect at the 
consolidated balance sheet date for assets and liabilities, historical rates for equity accounts, and average 
exchange rates for the consolidated statement of operations. Cash flows from operations are translated at 
the average exchange rate in effect for the period, while cash flows from investing and financing activities 
are translated at the exchange rate in effect at the date of the underlying transaction. Translation gains 
and  losses  are  recognized  as  a  component  of  accumulated  other  comprehensive  income  (loss)  in  the 
accompanying  consolidated  balance  sheets.  The  foreign  currency  translation  adjustment  balance 
included in accumulated other comprehensive income (loss) was $2.7 million of income and $6.4 million 
losses at December 31, 2023 and 2022, respectively. The aggregate foreign currency transaction gains and 
losses resulting from the conversion of the transaction currency to functional currency were $7.9 million of 
gains, $2.5 million of losses, and $5.3 million of losses for the years ended December 31, 2023, 2022, and 
2021, respectively, which are reflected in Other income (expense). 

Segment Information 

The  Company  manages  its  business  as  one  operating  segment,  the  development  and 
commercialization of innovative vaccines. The Company does not operate separate lines of business with 
respect  to  its  vaccine  or  vaccine  candidates.  Accordingly,  the  Company  does  not  have  separately 
reportable segments as defined by ASC Topic 280, Segment Reporting. 

Recent Accounting Pronouncements 

Not Yet Adopted 

In October 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards 
Update  (“ASU”)  2023-06,  Disclosure  Improvements  (“ASU  2023-06”),  to  clarify  or  improve  disclosure  and 
presentation requirements of a variety of topics and align the requirements in the FASB ASC with the SEC's 
regulations. The Company is currently evaluating ASU 2023-06 to determine its impact on the Company's 
consolidated financial statements and disclosures. 

In  December  2023,  the  FASB  issued  ASU  2023-09,  Improvements  to  Income  Tax  Disclosures  (“ASU 
2023-09”). The standard enhances transparency in income tax disclosures by requiring, on an annual basis, 
certain disaggregated information about a reporting entity’s effective tax rate reconciliation and income 
taxes paid. The ASU also requires disaggregated disclosure related to pre-tax income (or loss) and income 
tax  expense  (or  benefit)  and  eliminates  certain  disclosures  related  to  the  balance  of  an  entity’s 
unrecognized tax benefit and the cumulative amount of certain temporary differences. The ASU is effective 
for  the  Company  beginning  on  January  1,  2025.  The  Company  is  currently  evaluating  ASU  2023-09  to 
determine its impact on the Company's disclosures. 

Adopted 

In  June  2016,  the  FASB  issued  ASU  2016-13,  Financial  Instruments  -  Credit  Losses  (Topic  326): 
Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), with amendments in 2018, 2019, 
2020,  and  2022.  The  ASU  sets  forth  a  “current  expected  credit  loss”  model  that  requires  companies  to 
measure all expected credit losses for financial instruments held at the reporting date based on historical 
experience,  current  conditions,  and  reasonable  supportable  forecasts.  ASU  2016-13  applies  to  financial 
instruments that are not measured at fair value, including receivables that result from revenue transactions. 
The Company adopted ASU 2020-06 on January 1, 2023, using a modified retrospective approach, and it 
did not have a material impact on the Company’s consolidated financial statements.

(1)  Bad debt expense was $13.8 million in the year ended 2022. There was no bad debt expense in the year 
ended December 31, 2023 or 2021. There was a $6.2 million reversal of a bad debt expense during the 
year ended December 31, 2023 due to the collection of a previously recognized allowance for doubtful 
accounts.  To  estimate  the  allowance  for  doubtful  accounts,  the  Company  evaluates  the  credit  risk 
related  to  its  customers  based  on  historical  loss  experience,  economic  conditions,  the  aging  of 
receivables, and customer-specific risks. 

(2)  Deductions from Deferred revenue generally related to the recognition of revenue once performance 
obligations on a contract with a customer are met. Amount is comprised of $241.3 million, $0.4 billion, 
and  $1.4  billion  current  Deferred  revenue  and  $622.2  million,  $179.4  million,  and  $172.5  million  non-
current Deferred revenue as of December 31, 2023, 2022, and 2021 respectively. 

(3)  In 2023, deductions from Deferred revenue included $151.1 million that was realized in Revenue and 
$112.5 million related to the Amended and Restated UK Supply Agreement (as described below), that 
was  reclassified  to  Other  current  liabilities,  as  described  below.  In  2022,  deduction  from  Deferred 
revenue included $273.8 million that was realized in Revenue and $819.0 million, including $697.4 million 
related  to  the  Advance  Payment  Amount  (as  described  below)  related  to  the  Gavi  arbitration  and 
$112.5  million  related  to  the  Amended  and  Restated  UK  Supply  Agreement,  that  was  reclassified  to 
Other current liabilities, as described below. 

As of December 31, 2023, the aggregate amount of the transaction price allocated to performance 
obligations  that  were  unsatisfied  (or  partially  unsatisfied),  excluding  amounts  related  to  sales-based 
royalties,  the  Gavi  APA,  and  the  reduction  in  doses  related  to  the  Amended  and  Restated  SARS-CoV-2 
Vaccine Supply Agreement, dated as of July 1, 2022 (as amended on September 26, 2022, the “Amended 
and  Restated  UK  Supply  Agreement”)  between  the  Company  and  The  Secretary  of  State  for  Business, 
Energy  and  Industrial  Strategy  (as  assigned  to  the  UK  Health  Security  Agency),  acting  on  behalf  of  the 
government of the United Kingdom of Great Britain and Northern Ireland (the “Authority”), which amended 
and restated the Original UK Supply Agreement, was approximately $2 billion of which $863.5 million was 
in  Deferred  revenue.  Failure  to  meet  regulatory  milestones,  obtain  timely  supportive 
included 
recommendations from governmental advisory committees, or achieve product volume or delivery timing 
obligations under the Company’s APAs may require the Company to refund portions of upfront payments 
or  result  in  reduced  future  payments,  which  could  adversely  impact  the  Company’s  ability  to  realize 
revenue from its unsatisfied performance obligations. The timing to fulfill performance obligations related to 
APAs will depend on timing of product manufacturing, receipt of marketing authorizations for additional 
indications, delivery of doses based on customer demand, and the ability of the customer to request variant 
vaccine in place of the prototype vaccine under certain of the Company’s APAs. The remaining unfilled 
performance obligations not related to APAs are expected to be fulfilled in less than one year.

Under the terms of the Gavi APA and a separate purchase agreement between Gavi and SIIPL, 1.1 
billion doses of the prototype vaccine were to be made available to countries participating in the COVAX 
Facility. The Company expected to manufacture and distribute 350 million doses of the prototype vaccine 
to countries participating under the COVAX Facility. Under a separate purchase agreement with Gavi, SIIPL 
was expected to manufacture and deliver the balance of the 1.1 billion doses of prototype vaccine for 
low- and middle-income countries participating in the COVAX Facility. The Company expected to deliver 
doses with antigen and adjuvant manufactured at facilities directly funded under the Company's funding 
agreement with CEPI, with initial doses supplied by SIIPL and SLS under a supply agreement. The Company 
expected 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 could prioritize such doses to low- 
and middle- income countries, at lower prices. Additionally, the Company could provide additional doses 
of prototype vaccine, to the extent available from CEPI-funded manufacturing facilities, in the event that 
SIIPL could not materially deliver expected vaccine doses to the COVAX Facility. Under the agreement, the 
Company received an upfront payment of $350.0 million from Gavi in 2021 and an additional payment of 
$350.0 million in 2022 related to the Company’s achieving an emergency use license for the Company’s 
prototype vaccine by the World Health Organization (“WHO”) (the “Advance Payment Amount”).  

On November 18, 2022, the Company delivered written notice to Gavi to terminate the Gavi APA 
on  the  basis  of  Gavi’s  failure  to  procure  the  purchase  of  350  million  doses  of  the  Company’s  prototype 
vaccine from the Company as required by the Gavi APA. As of November 18, 2022, the Company had only 
received orders under the Gavi APA for approximately 2 million doses. On December 2, 2022, Gavi issued 
a  written  notice  purporting  to  terminate  the  Gavi  APA  based  on  Gavi’s  contention  that  the  Company 
repudiated the agreement and, therefore, materially breached the Gavi APA. Gavi also contended that, 
based on its purported termination of the Gavi APA, it was entitled to a refund of the Advance Payment 
Amount less any amounts that have been credited against the purchase price for binding orders placed 
by a  buyer  participating in the COVAX Facility.  As of December 31,  2023 and 2022, the remaining  Gavi 
Advance Payment was $696.4 million and $697.4 million, respectively, pending resolution of the dispute with 
Gavi  related  to  the return  of  the  remaining  Advance  Payment  Amount,  and was  classified  within  Other 
current liabilities in the Company’s consolidated balance sheet. On January 24, 2023, Gavi filed a demand 
for  arbitration  with  the  International  Court  of  Arbitration  based  on  the  claims  described  above.  The 
Company filed its Answer and Counterclaims on March 2, 2023. On April 5, 2023, Gavi filed its Reply to the 
Company’s Counterclaims. On February 16, 2024, the Company and Gavi entered into a Termination and 
Settlement  Agreement  (the  “Gavi  Settlement  Agreement”)  terminating  the  Gavi  APA,  settling  the 
arbitration  proceedings  and  releasing  both  parties  of  all  claims  arising  from,  under  or  otherwise  in 
connection with the Gavi APA. Pursuant to the Gavi Settlement Agreement, the Company is responsible 
for payment to Gavi of (i) an initial settlement payment of $75 million, which the Company paid on February 
20, 2024, and (ii) deferred payments, in equal annual amounts of $80 million payable each calendar year 
through a deferred payment term ending December 31, 2028. The deferred payments are due in variable 
quarterly  installments  beginning  in  the  first  quarter  of  2024  and  total  $400  million  during  the  deferred 
payment term. Such deferred payments may be reduced through Gavi’s use of an annual vaccine credit 
equivalent  to  the  unpaid  balance  of  such  deferred  payments  each  year,  which  may  be  applied  to 
qualifying  sales  of  any  of  the  Company’s  vaccines  for  supply  to  certain  low-income  and  lower-middle 
income countries. The Company has the right to price the vaccines offered to such low-income and lower-
middle income countries in its discretion, and, when utilized by Gavi, the Company will credit the actual 
price per vaccine paid against the applicable credit. The Company intends to price vaccines offered via 
the tender process, consistent with its shared goal with Gavi to provide equitable access to those countries. 
Also, pursuant to the Gavi Settlement Agreement, the Company granted Gavi an additional credit of up 
to $225 million that may be applied against qualifying sales of any of the Company’s vaccines for supply 
to  such  low-income  and  lower-middle  income  countries  that  exceed  the  $80  million  deferred  payment 
amount  in  any  calendar  year  during  the  deferred  payment  term.  In  addition,  the  Company  and  Gavi 
entered into a security agreement pursuant to which Novavax granted Gavi a security interest in accounts 
receivable  from  SIIPL  under  the  SIIPL  R21  Agreement  (see  Note  4),  which  will  continue  for  the  deferred 
payment  term  of  the  Gavi  Settlement  Agreement.  On  February  22,  2024,  the  claims  and  counterclaims 
were dismissed with prejudice.

In  the  fourth  quarter  of  2023,  the  Company  commenced  sales  of  COVID-19  Vaccine  to  the  U.S. 
commercial market, in addition to continuing sales to various international governments. Product sales in 
the U.S. are primarily made through large pharmaceutical wholesale distributors at the WAC. Product sales 
in the U.S. are recorded net of gross-to-net deductions, as described in Note 2.

The  Company  has  an  APA  with  the  Commonwealth  of  Australia  for  the  purchase  of  doses  of 
COVID-19 Vaccine (the “Australia APA”). In May 2023, the Company extended a credit for certain doses 
delivered and recognized within product revenue in 2022 that qualified for replacement under the Australia 
APA. This credit is the result of a single lot sold to the Australian government that upon pre-planned 6-month 
stability  testing  was  found  to  have  fallen  below  the  defined  specifications  and  the  lot  therefore  was 
removed from the market. The credit will be applied against the future sale of doses to Australia and, during 
the year ended December 31, 2023, the Company recorded a reduction of $64.7 million in product sales, 
with a corresponding increase to Deferred revenue, non-current. In July 2023, the Company amended the 
Australia APA to provide for replacement doses and to extend the delivery schedule through 2025. As of 
February 2024, the Company had not yet received Therapeutic Goods Administration (“TGA”) authorization 
or  delivered  doses  as  contemplated  in  the  July  2023  amendment  and  is  in  active  discussions  with  the 
Australian government on both the TGA authorization and delivery of the doses previously scheduled for 
the fourth quarter of 2023. In February 2024, the Company received notice from the Australian government 
purporting to cancel its order for such prototype vaccine doses. The Company believes the cancellation 
was not proper under the amended Australia APA. However, if such a cancellation were determined to be 
allowable, $6.0 million of the deferred revenue would become a credit towards future deliveries of doses 
and  approximately  $48  million  of  the  contract  value  related  to  future  deliverables  would  no  longer  be 
available. 

The  Company  has  an  APA  with  the  European  Commission  (“EC”)  acting  on  behalf  of  various 
European  Union  member  states  to  supply  a  minimum  of  20  million  and  up  to  100  million  initial  doses  of 
prototype vaccine, with the option for the EC to purchase an additional 100 million doses up to a maximum 

F-23 

 
 
 
 
 
 
 
 
 
 
 
   
  
 
 
 
 
 
 
aggregate  of  200 million  doses  in  one or  more  tranches,  through  2023.  Under  the terms  of  the APA,  the 
Company  agreed  to  manufacture  the  vaccine  in  facilities  located  in  the  European  Union  and  ensure 
continued efficacy of the vaccine against variants of the SARS-CoV-2 virus. Pursuant to the terms of the 
APA, the Company is prohibited from supplying prototype vaccine to any third party if such delivery would 
impede or limit the fulfillment of the Company’s obligations to the EC under the APA, except with respect 
to the Company’s obligations under the Gavi APA. In 2022, the Company was notified by the EC that it was 
cancelling approximately 7 million doses of its prior commitment originally scheduled for delivery in the first 
and second quarters of 2022, in accordance with the APA, and reducing the order to approximately 63 
million doses. In January 2023, the Company finalized a revised delivery schedule for the remaining 20 million 
committed  doses  under  the  APA  that  were  originally  scheduled  for  delivery  during  the  first  and  second 
quarters of 2022. The APA expired in August 2023 and required that any open and outstanding orders from 
European Union member states be satisfied by February 2024. Since August 2023, any additional doses have 
been managed by amending outstanding orders with deliveries made by February 2024. 

The  Company  has  an  APA  with  His  Majesty  the  King  in  Right  of  Canada  as  represented  by  the 
Minister of Public Works and Government Services, as successor in interest to Her Majesty the Queen in Right 
of  Canada,  as  represented  by  the  Minister  of  Public  Works  and  Government  Services  (the  “Canadian 
government”),  for  the  purchase  of  doses  of  COVID-19  Vaccine  (the  “Canada  APA”).  In  April  2023,  the 
Company amended the “Canada APA”, pursuant to which the Canadian government forfeited certain 
doses originally scheduled for delivery in 2022 for a payment of $100.4 million, which the Company received 
in the second quarter of 2023. In June 2023, the Company entered into an additional amendment (the 
“June 2023 Amendment”) to the Canada APA. Pursuant to the June 2023 Amendment, (i) the Canadian 
government forfeited certain doses of COVID-19 Vaccine previously scheduled for delivery and agreed to 
pay a total amount of $349.6 million to the Company in two equal installments, which total amount equaled 
the remaining balance owed by the Canadian government with respect to such forfeited vaccine doses, 
(ii) the amount of doses of COVID-19 Vaccine due for delivery was reduced, (iii) the delivery schedule for 
the remaining doses of COVID-19 Vaccine to be delivered was revised, and (iv) the parties agreed Novavax 
would use the Biologics Manufacturing Centre (“BMC”) Inc. to produce bulk antigen for doses in 2024 and 
2025. The June 2023 Amendment maintained the total contract value of the original Canada APA. The first 
Installment of $174.8 million was payable upon execution of the June 2023 Amendment and received by 
Novavax in July 2023, and the second installment of $174.8 million was contingent and payable upon the 
delivery  of  vaccine  doses  in  the  second  half  of  2023  and  received  by  Novavax  in  January  2024.  The 
Canadian  government  may  terminate  the  Canada  APA,  as  amended,  if  the  Company  fails  to  receive 
regulatory approval for its COVID-19 Vaccine using bulk antigen produced at BMC on or before December 
31, 2024. The Company’s 2024 plans do not currently anticipate the submission for regulatory approval of 
its  COVID-19  Vaccine  using  bulk  antigen  produced  at  BMC,  and  it  plans  to  work  with  the  Canadian 
government on an amendment that addresses possible alternatives, which may not be achievable. As of 
December  31,  2023,  $102.8  million  was  classified  as  short-term  Deferred  revenue  and  $485.3  million  was 
classified as long-term Deferred revenue with respect to the Canadian APA in the Company’s consolidated 
balance  sheet.  If  the  Canadian  government  terminates  the  Canada  APA,  $28.0  million  of  the  deferred 
revenue would become refundable and approximately $224 million of the contract value related to future 
deliverables  would  no  longer  be  available.  Pursuant  to  the  June  2023  Amendment,  Novavax  and  the 
Canadian government will endeavor to expand the previously agreed in-country commitment to Canada 
and  to  further  partner  to  provide  health,  economic,  and  future  pandemic  preparedness  benefits  to 
Canada, which value may be provided through a number of activities, including without limitation, capital 
investments, the performance of activities or services, or the provision of technology or intellectual property 
licenses. Further, the parties will endeavor to enter into a memorandum of understanding (the “MOU”) to 
illustrate the Company’s ability to deliver such benefits over a 15-year period with an aggregate value of 
not less than 100% of the amount remaining to be paid under the June 2023 Amendment and ultimately 
received by the Company. As of December 31, 2023, discussions regarding the MOU were ongoing. The 
Company agreed to hold, when received, $20.0 million of the second installment payment in escrow for 
the benefit of the Canadian government, which amount is the sole recourse available to the Canadian 
government in the event of non-performance under the MOU.  

In July 2022, the Company entered into an Amended and Restated SARS-CoV-2 Vaccine Supply 
Agreement (as amended on September 26, 2022, the “Amended and Restated UK Supply Agreement”) 

F-24 

 
 
with The Secretary of State for Business, Energy and Industrial Strategy (as assigned to the UK Health Security 
Agency), acting on behalf of the government of the United Kingdom of Great Britain and Northern Ireland 
(the “Authority”), which amended and restated in its entirety the SARS-CoV-2 Vaccine Supply Agreement, 
dated October 22, 2020, between the parties (the “Original UK Supply Agreement”). Under the Original UK 
Supply Agreement, the Authority agreed to purchase 60 million doses of prototype vaccine and made an 
upfront payment to the Company. Under the terms of the Amended and Restated UK Supply Agreement, 
the Authority agreed to purchase a minimum of 1 million doses and up to an additional 15 million doses 
(the “Conditional Doses”) of prototype vaccine, with the number of Conditional Doses contingent on, and 
subject to reduction based on, the Company’s timely achievement of supportive recommendations from 
the Joint Committee on Vaccination and Immunisation (the “JCVI”) that is approved by the UK Secretary 
of State for Health, with respect to use of the vaccine for (a) the general adult population as part of a SARS-
CoV-2 vaccine booster campaign in the United Kingdom or (b) the general adolescent population as part 
of  a  SARS-CoV-2  vaccine  booster  campaign  in  the  United  Kingdom  or  as  a  primary  series  SARS-CoV-2 
vaccination,  excluding  where  that  recommendation  relates  only  to  one  or  more  population  groups 
comprising  less  than  one  million  members  in  the  United  Kingdom.  If  the  Authority  did  not  purchase  the 
Conditional  Doses  or  the  number  of  such  Conditional  Doses  was  reduced  below  15  million  doses  of 
prototype vaccine, the Company would have to repay up to $225.0 million related to the upfront payment 
previously received from the Authority under the Original UK Supply Agreement. Under the Amended and 
Restated UK Supply Agreement, the Authority also has the option to purchase up to an additional 44 million 
doses, in one or more tranches, through 2024. 

As of November 30, 2022, the JCVI had not made a supportive recommendation with respect to 
prototype  vaccine,  thereby  triggering,  under  the  terms  of  the  Amended  and  Restated  UK  Supply 
Agreement, (i) a reduction of the number of Conditional Doses from 15 million doses to 7.5 million doses, 
which reduced number of Conditional Doses are contingent on, and subject to further reduction based 
on, the Company’s timely achievement by November 30, 2023 of a supportive recommendation from JCVI 
that is approved by the UK Secretary of State for Health as described in the paragraph above, and (ii) an 
obligation for the Company to repay $112.5 million related to the upfront payment previously received from 
the Authority under the Original UK Supply Agreement. In April 2023, the Company repaid the $112.5 million 
related to the November 30, 2022 triggering event. As of November 30, 2023, the JCVI had not made a 
supportive recommendation with respect to the prototype vaccine, thereby triggering a reduction in the 
number  of  Conditional  Doses  from  7.5  million  doses  to  zero.  As  of  February  2024,  the  Company  is  in 
discussions  with  the  Authority  regarding  the  treatment  of  the  remaining  upfront  payment  previously 
received of $112.5 million, which is reflected in Other current liabilities.

The  original  USG  Agreement  required  the  Company  to  conduct  certain  clinical,  regulatory,  and 
other activities, including a pivotal Phase 3 clinical trial to determine the safety and efficacy of prototype 
vaccine,  and  to  manufacture  and  deliver  to  the  U.S.  government  100  million  doses  of  the  vaccine 
candidate.  Funding  under  the  USG  Agreement  is  payable  to  the  Company  for  various  development, 
clinical  trial,  manufacturing,  regulatory,  and  other  activities.  The  USG  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  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 USG Agreement. As of 
December 31, 2023, the Company has recognized the full $1.8 billion funding under the USG Agreement in 
revenue.  

Coalition for Epidemic Preparedness Innovations 

In  May  2020,  the  Company  entered  into  a  restated  funding  agreement  which  was  amended  in 
November  2020  with  CEPI,  under  which  CEPI  agreed  to  provide  funding  of  up  to  $399.5  million  to  the 
Company to support the development of prototype vaccine. The agreement provided up to $257.0 million 
in CEPI Grant Funding and up to $142.5 million in CEPI Forgivable Loan Funding, which are loans in the form 
of one or more forgivable no-interest term loans to fund certain manufacturing activities and are not subject 
to restrictive or financial covenants. As of December 31, 2023 and 2022, the Company had recognized total 
revenue related to CEPI of $358.6 million, with the unused amounts primarily related to CEPI Forgivable Loan 
Funding. Payments received under the CEPI Forgivable Loan Funding are only repayable if project vaccine, 
as defined under the CEPI funding agreement, manufactured by the CMO network funded by CEPI is sold 
to one or more third parties (which could include sales credited under the Gavi Settlement Agreement), 
and such sales cover the Company’s costs of manufacturing such vaccine, not including manufacturing 
costs funded by CEPI. The timing and amount of any loan repayments is currently uncertain. 

Royalties and Other 

Royalties  and  other  includes  royalty  milestone  payments,  sales-based  royalties,  and  Matrix-M™ 

adjuvant sales.  

During the year ended December 31, 2023, the Company recognized $8.5 million in revenue related 
to license fees, and $16.5 million in revenue related to a Matrix-M™ adjuvant sales. During the year ended 
December 31, 2023, the Company did not recognize revenue related to milestone payments. 

During the year ended December 31, 2022, the Company recognized $9.0 million in revenue related 
to sales-based royalties, $20.0 million related to milestone payments, and $15.0 million in revenue related to 
a Matrix-M™ adjuvant sales. 

During  the  year  ended  December  31,  2021,  the  Company  recognized  $178.6  million  in  revenue 

related to sales-based royalties and $20.0 million related to milestone payments.  

Note 4 – Collaboration, License, and Supply Agreements  

SIIPL 

The Company previously granted SIIPL exclusive and non-exclusive licenses for the development, 
co-formulation,  filling  and  finishing,  registration,  and  commercialization  of  its  prototype  vaccine,  its 
proprietary  COVID-19  variant  antigen  candidate(s),  and  its  CIC  vaccine  candidate.  SIIPL  agreed  to 
purchase the Company's Matrix-M™ adjuvant and the Company granted SIIPL a non-exclusive license to 
manufacture  the  antigen  drug  substance  component  of  the  Company’s  COVID-19  Vaccine  in  SIIPL’s 
licensed territory solely for use in the manufacture of COVID-19 Vaccine. The Company and SIIPL equally 
split  the  revenue  from  SIIPL’s  sale  of  COVID-19  Vaccine  in  its  licensed  territory,  net  of  agreed  costs.  The 

F-26 

 
 
 
 
 
 
 
 
 
 
Company also has a supply agreement with SIIPL and SLS under which SIIPL and SLS supply the Company 
with  prototype  vaccine,  its  proprietary  COVID-19  variant  antigen  candidate(s),  and  its  CIC  vaccine 
candidate  for  commercialization  and  sale  in  certain  territories,  as  well  as  a  contract  development 
manufacture agreement with SLS, under which SLS manufactures and supplies finished vaccine product to 
the Company using antigen drug substance and Matrix-M™ adjuvant supplied by the Company. In March 
2020, the Company entered into an agreement with SIIPL that granted SIIPL a non-exclusive license for the 
use  of  Matrix-M™  adjuvant  supplied  by  the  Company  to  develop,  manufacture,  and  commercialize 
R21/Matrix-M™  adjuvant  (“SIIPL  R21  Agreement”),  a  malaria  vaccine  created  by  the  Jenner  Institute, 
University of Oxford (“R21/Matrix-M™”). In December 2023 received prequalification by the WHO. Under 
the  SIIPL  R21  Agreement,  SIIPL  purchases  the  Company's  Matrix-M™  adjuvant  for  use  in  development 
activities at cost and for commercial purposes at a tiered commercial supply price, and pays a royalty in 
the  single-to  low-  double-digit  range  based  on  vaccine  sales  for  a  period  of  15  years  after  the  first 
commercial sale of the vaccine in each country.  

Takeda Pharmaceutical Company Limited 

The Company has a collaboration and license agreement with Takeda Pharmaceutical Company 
Limited  (“Takeda”)  under  which  the  Company  granted  Takeda  an  exclusive  license  to  develop, 
manufacture,  and  commercialize  the  Company’s  COVID-19  Vaccine  in  Japan.  Under  the  agreement, 
Takeda purchases Matrix-M™ adjuvant from the Company to manufacture doses of COVID-19 Vaccine, 
and the Company is entitled to receive milestone and sales-based royalty 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  COVID-19  Vaccine.  In  September  2021,  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  its  prototype  vaccine.  In  February  2023,  MHLW  canceled  the  remainder  of  doses  under  its 
agreement with Takeda. As a result, it is uncertain whether the Company will receive future sales-based 
royalty payments from Takeda under the terms and conditions of their current collaboration and licensing 
agreement. For the year ended December 31, 2023, the Company recognized $6.0 million of revenue as 
consideration  for  changes  to  certain  terms  of  the  license  agreement  which  is  included  in  Royalties  and 
other revenue on the consolidated statements of operations. For the year ended December 31, 2022, the 
Company  recognized  $20.0  million,  upon  the  sale  of  prototype  vaccine  in  Japan,  which  is  included  in 
Royalties and other revenue on the consolidated statements of operations.  

Bill & Melinda Gates Medical Research Institute 

In May 2023, the Company entered into a 3-year agreement with the Bill & Melinda Gates Medical 

Research Institute to provide the Company’s Matrix-M™ adjuvant for use in preclinical vaccine research. 

SK bioscience, Co., Ltd. 

In February 2021, the Company entered into a Collaboration and License Agreement (“CLA”) with 
SK  bioscience,  Co.,  Ltd.  (“SK”)  to  manufacture  and  commercialize  its  prototype  vaccine  for  sale  to  the 
government of South Korea. The CLA was amended in December 2021 and July 2022 to include the sale of 
its prototype vaccine to Thailand and Vietnam and to supply the Company with the antigen component 
of prototype vaccine for use in the final drug product globally, including product to be distributed by the 
COVAX Facility. Under the CLA, as amended, SK agreed to pay the Company a royalty on the sale of its 
prototype  vaccine  in  the  low  to  middle  double-digit  range.  The  CLA  was  in  addition  to  the  Company's 
existing manufacturing arrangement with SK under a Development and Supply Agreement (“DSA”) entered 
into in August 2020. In July 2022, the Company signed an additional agreement with SK for the technology 
transfer of the Company’s proprietary COVID-19 variant antigen materials so that SK can manufacture the 
drug substance targeting COVID-19 variants, including the Omicron subvariants. The companies also signed 
an agreement to manufacture and supply its prototype vaccine in a prefilled syringe. 

In June 2023, the Company entered into a material transfer agreement with SK for the use by SK of 
the  Company’s  Matrix-M™  adjuvant  in  preclinical  vaccine  experiments  for  shingles,  influenza,  and  pan-
sarbecovirus vaccine. 

F-27 

 
 
 
 
 
 
 
 
In August 2023, the Company and SK entered into a Settlement Agreement and General Release 
(the “Settlement Agreement”) regarding mutual release by the parties of all claims arising from or in relation 
to statements of work (“SOWs”) canceled by the Company under the DSA and the CLA (collectively the 
“Business Agreements”), and other SOWs under the Business Agreements (collectively, the “Subject SOWs”), 
in  each  case,  in  connection  with  the  cessation  of  all  drug  substance  and  drug  product  manufacturing 
activity at SK for supply to the Company. Subject SOWs canceled by the Company under the Settlement 
Agreement  included  (i)  Statement  of  Work  No.  1  dated  as  of  December  23,  2021  as  amended  to  date 
under the CLA; (ii) Statement of Work No. 5 dated as of July 18, 2022 under the DSA; and (iii) Statement of 
Work No. 6 dated as of July 18, 2022, and as amended as of December 28, 2022 under the DSA.  

Pursuant to the Settlement Agreement, the Company is responsible for payment of $149.8 million to 
SK  in  connection  with  the  cancellation  of  manufacturing  activity  for  the  SOWs  under  the  Business 
Agreements, of which (i) $130.4 million was paid in August 2023 and (ii) the remaining balance was paid in 
November 2023. Under the Settlement Agreement, the Company and SK agreed to a wind down plan with 
respect to the remaining products, materials and equipment under the SOWs. 

Under the Settlement Agreement, the Company and SK agreed to remove certain restrictions under 
the CLA that have been triggered by the launch of SK’s competing vaccine SKYCovione™ in the Republic 
of Korea. In addition, the Company agreed to extend the term of an exclusive license to SK under the CLA 
for the exploitation of antigen and vaccine products utilizing Company’s proprietary coronavirus vaccine 
antigens  and  Matrix-M  adjuvant  in  certain  territories.  The  Company  recorded  $4.0  million  to  Deferred 
revenue related to the extended licenses granted to SK under the Settlement Agreement.  

In  August  2023,  the  Company  also  entered  into  a  Securities  Subscription  Agreement  (the 
“Subscription  Agreement”)  with  SK,  pursuant  to  which  the Company  agreed  to  sell  and issue to  SK,  in  a 
private placement (the “Private Placement”), 6.5 million shares of the Company’s common stock, par value 
$0.01 per share (the “Shares”) at a price of $13.00 per share for aggregate gross proceeds to the Company 
of approximately $84.5 million. The closing of the Private Placement occurred on August 10, 2023. The fair 
value of the Company’s common stock on the date of closing, based on the quoted market price, was 
$46.5 million, which results in a premium paid by SK of approximately $38 million. 

The  Settlement  Agreement  and  the  Subscription  Agreement  were  negotiated  concurrently 
between  the  parties,  and  therefore  were  combined  for  accounting  purposes  and  analyzed  as  a  single 
arrangement. As a result, the Company recorded the $46.5 million fair value of common stock issued to SK, 
based on the quoted market price on the date of close, as an equity transaction. The remaining elements 
of the arrangement were deemed to relate to the settlement of the Company’s outstanding liabilities due 
to SK. These elements consist primarily of the cash payable to SK of $149.8 million, offset by the premium 
paid on the common stock purchase by SK of $38.0 million, which resulted in a net gain upon derecognition 
of  the  liabilities  due  to  SK  of  $79.2  million  in  connection  with  the  settlement.  As  a  result,  during  the  year 
ended December 31, 2023, the Company recorded this net gain of $79.2 million between research and 
development  expense,  for  $57.7  million,  and  cost  of  sales,  for  $21.5  million,  proportionally  based  on  the 
where the underlying costs were originally recorded. 

Other Supply Agreements 

On  September  30,  2022,  the  Company,  FUJIFILM  Diosynth  Biotechnologies  UK  Limited  (“FDBK”), 
FUJIFILM  Diosynth  Biotechnologies  Texas,  LLC  (“FDBT”),  and  FUJIFILM  Diosynth  Biotechnologies  USA,  Inc. 
(“FDBU” and together with FDBK and FDBT, “Fujifilm”) entered into a Confidential Settlement Agreement 
and Release (the “Fujifilm Settlement Agreement”) regarding amounts due to Fujifilm in connection with 
the termination of manufacturing activity at FDBT under the Commercial Supply Agreement (the “Fujifilm 
CSA”)  dated  August  20,  2021  and  Master  Services  Agreement  dated  June  30,  2020  and  associated 
statements of work (the “Fujifilm MSA”) by and between the Company and Fujifilm. The Fujifilm MSA and 
Fujifilm CSA established the general terms and conditions applicable to Fujifilm’s manufacturing and supply 
activities related to prototype vaccine under the associated statements of work. 

F-28 

 
 
 
 
 
 
 
Pursuant to the Fujifilm Settlement Agreement, the Company agreed to pay up to $185.0 million (the 
“Settlement Payment”) to Fujifilm in connection with cancellation of manufacturing activity at FDBT under 
the CSA, of which (i) $47.8 million, constituting the initial reservation fee under the CSA, was credited against 
the Settlement Payment on September 30, 2022 and (ii) the remaining balance was to be paid in four equal 
quarterly installments of $34.3 million each, which began on March 31, 2023. Under the Fujifilm Settlement 
Agreement,  the final  two  quarterly installments due  to  Fujifilm  were  subject  to  Fujifilm’s  obligation to  use 
commercially  reasonable  efforts  to  mitigate  losses  associated  with  the  vacant  manufacturing  capacity 
caused by the termination of manufacturing activities at FDBT under the CSA. Any replacement revenue 
achieved by Fujifilm’s mitigation efforts between July 1, 2023 and December 31, 2023 would offset the final 
two  settlement  payments  owed  by  the  Company.  On  October  2,  2023,  the  Company  sent  a  notice  of 
breach under the Fujifilm Settlement Agreement to Fujifilm setting forth the Company’s position that Fujifilm 
had not used commercially reasonable efforts to mitigate losses. The Company withheld two installments 
of $34.3 million due to Fujifilm on September 30, 2023 and December 31, 2023, pending resolution of the 
issues  identified  in  the  notice  of  breach.  On  October  30,  2023,  FDBT  filed  a  demand  for  arbitration  with 
Judicial Arbitration and Mediation Services (“JAMS”) seeking payment of the third quarter installment of the 
Settlement  Payment.  As  of  December  31,  2023,  the remaining  payment  of  $68.6 million  was  reflected  in 
Accrued expenses. 

The  Company  continues  to  assess  its  manufacturing  needs  and  intends  to  modify  its  global 
manufacturing footprint consistent with its contractual obligations to supply, and anticipated demand for, 
its COVID-19 Vaccine, and in doing so, recognizes that significant costs may be incurred.

The  Company  has  embedded  leases  related  to  multiple  manufacturing  supply  agreements  with 
CMOs  and  CMOS  to  manufacture  COVID-19  Vaccine,  as  well  as  operating  and  finance  leases  for  its 
research and development and manufacturing facilities, corporate headquarters and offices. During the 
year ended December 31, 2023, the Company continued to align its global manufacturing footprint as a 
result of its ongoing assessment of manufacturing needs consistent with its contractual obligations related 
to the supply, and anticipated demand for, its COVID-19 Vaccine. 

During the years ended December 31, 2023 and 2022, the Company modified certain of its CMO 
and  CDMO  agreements  that  had  previously  been  determined  to  represent  embedded  leases  and,  in 
accordance with its policy, the Company remeasured and reallocated the remaining consideration under 
the  contracts  and  reassessed  the  lease  classification  as  of  the  effective  dates  of  the  respective 
modifications. During the year ended December 31, 2023 and 2022, as a result of new or modified leases, 
the Company recognized ROU assets, net of credits on modifications, and a corresponding lease liability 
of $6.8 million and $18.6 million, respectively, for its long-term finance and operating leases embedded in 
CMO and CDMO manufacturing supply agreements. Also, during the year ended December 31, 2023, the 
Company recorded an impairment charge of $6.1 million in Cost of sales related to an embedded lease 
agreement with a CMO for production capacity in excess of production needs. 

During 2020, the Company entered into a lease agreement for the premises located at 700 Quince 
Orchard  Road,  Gaithersburg,  Maryland  ("700QO").  The  lease  is  for  approximately  170,000  square  feet  of 
space that the Company is using for manufacturing, research and development, and offices. The term of

the lease expires in 2035 with options to extend the lease. The lease provides for an annual base rent of $5.8 
million that is subject to future rent increases and obligates the Company to pay building operating costs. 
During  the  year  ended  December  31,  2022,  the  Company  obtained  the  right  to  direct  the  use  of,  and 
obtain substantially all of the benefit from, certain floors located at the premises and recognized an ROU 
asset  and  related  lease  obligation  of  $73.2  million  as  lease  commencement  for  accounting  purposes 
occurred in 2022. During the year ended December 31, 2023, the Company obtained the right to direct 
the use of, and obtain substantially all of the benefit from, the remaining floors located at the premises and 
recognized a ROU asset and related lease obligation of $96.5 million as the lease commencement dates 
for accounting purposes had occurred for such remaining floors. The lease obligation was reduced by $73.4 
million for prepaid rent and prior costs incurred on behalf of the landlord during 2023. 

As of December 31, 2023, facility leases, including the 700QO lease, have expirations that range 
from  approximately  two  to  thirteen  years,  some  of  which  include  options  to  extend  the  lease  term.  The 
facility  leases  contain  provisions  for  future  rent  increases  and  obligate  the  Company  to  pay  building 
operating costs. 

During the year ended December 31, 2023, the Company recorded an impairment charge of $5.9 
million related to ROU facility leases used for research and development, manufacturing and offices space 
that are impacted by the Restructuring Plan (see Note 17).

2027 Convertible Notes 

In December 2022, the Company issued $175.3 million aggregate principal amount of convertible 
senior unsecured notes that will mature on December 15, 2027 (the “2027 Notes”), unless earlier converted, 
redeemed,  or  repurchased.  The  2027  Notes  were  issued  in  a  private  placement  to  qualified  institutional 
buyers pursuant to Rule 144A under the Securities Act of 1933, as amended, and pursuant to an indenture 
dated December 20, 2022 (the “2027 Indenture”) between the Company and The Bank of New York Mellon 
Trust Company, N.A., as trustee. Concurrently with the issuance of the 2027 Notes, the Company completed 
a public offering of shares of its common stock (see Note 11). The Company received $166.4 million in net 
proceeds  from  the  issuance  of  the  2027  Notes  after  deducting  the  initial  purchasers’  fees  and  the 
Company’s  offering  expenses.  The  2027  Notes  bear  cash  interest  at  a  rate  of  5.00%  per  year,  payable 
semiannually in arrears on June 15 and December 15 of each year, beginning on June 15, 2023. 

The 2027 Notes are convertible at the option of the holders at any time prior to the close of business 
on the business day immediately preceding September 15, 2027, only under the following circumstances: 
(1) during any calendar quarter commencing after the calendar quarter ending on March 31, 2023 (and 
only during such calendar quarter), if the last reported sale price of the Company’s common stock for at 
least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending 
on, and including, the last trading day of the immediately preceding calendar quarter is greater than or 
equal to 130% of the conversion price for the 2027 Notes on each applicable trading day; (2) during the 
five business day period after any ten consecutive trading day period (the “measurement period”) in which 
the trading price (as defined in the 2027 Indenture) per $1,000 principal amount of the 2027 Notes for each 
trading day of the measurement period was less than 98% of the product of the last reported sale price of 
the Company’s common stock and the conversion rate for the 2027 Notes on each such trading day; (3) if 
the  Company  calls  such  2027  Notes  for  redemption,  at  any  time  prior  to  the  close  of  business  on  the 
scheduled  trading  day  immediately  preceding  the  redemption  date,  but  only  with  respect  to  the  2027 
Notes  called  (or  deemed  called)  for  redemption;  and  (4)  upon  the  occurrence  of  specified  corporate 
events as set forth in the 2027 Indenture. On or after September 15, 2027, until the close of business on the 
business day immediately preceding the maturity date (December 15, 2027), holders of the 2027 Notes may 

F-34 

 
 
 
  
 
 
   
 
 
 
 
 
 
   
 
 
 
 
 
 
 
 
 
 
 
 
  
 
 
 
 
 
 
convert  all  or  any  portion  of  their  2027  Notes  at  any  time,  regardless  of  the  foregoing  conditions.  Upon 
conversion, the Company may satisfy its conversion obligation by paying or delivering, as the case may be, 
cash, shares of the Company’s common stock, or a combination of cash and shares of the Company’s 
common  stock,  at  the  Company’s  election,  in  the  manner  and  subject  to  the  terms  and  conditions 
provided in the 2027 Indenture. 

The conversion rate for the 2027 Notes will initially be 80.0000 shares of the Company’s common 
stock per $1,000 principal amount of 2027 Notes, which is equivalent to an initial conversion price of $12.50 
per share of common stock. The initial conversion price of the 2027 Notes represents a conversion premium 
of 25% of the public offering price in the Company’s concurrent common stock offering that closed on 
December 20, 2022 (see Note 11). The conversion rate for the 2027 Notes is subject to adjustment under 
certain circumstances in accordance with the terms of the 2027 Indenture. In addition, following certain 
corporate events that occur prior to the maturity date of the 2027 Notes or if the Company delivers a notice 
of redemption in respect of the 2027 Notes, the Company will, under certain circumstances, increase the 
conversion rate of the 2027 Notes for a holder who elects to convert its 2027 Notes (or any portion thereof) 
in  connection  with  such  a  corporate  event  or  convert  its  2027  Notes  called  (or  deemed  called)  for 
redemption during the related redemption period (as defined in the 2027 Indenture), as the case may be. 

 The Company may not redeem the 2027 Notes prior to December 22, 2025. The Company may 
redeem for cash all or any portion of the 2027 Notes, at its option, on or after December 22, 2025, if the last 
reported sale price of the common stock has been at least 130% of the conversion price for the 2027 Notes 
then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading 
day  period  (including  the  last  trading  day  of  such  period)  ending  on,  and  including,  the  trading  day 
immediately preceding the date on which the Company provides notice of redemption at a redemption 
price equal to 100% of the principal amount of the 2027 Notes to be redeemed, plus accrued and unpaid 
interest, to, but excluding, the redemption date. If the Company redeems less than all the outstanding 2027 
Notes, at least $50 million aggregate principal amount of 2027 Notes must be outstanding and not subject 
to redemption as of the date of the relevant notice of redemption. No sinking fund is provided for the 2027 
Notes. 

If the Company undergoes a Fundamental Change (as defined in the 2027 Indenture), holders may 
require, subject to certain conditions and exceptions as set forth in the 2027 Indenture, the Company to 
repurchase for cash all or any portion of their 2027 Notes at a Fundamental Change repurchase price equal 
to 100% of the principal amount of the 2027 Notes to be repurchased, plus accrued and unpaid interest, 
to, but excluding, the Fundamental Change repurchase date. If a holder of the 2027 Notes converted upon 
a Make-Whole Fundamental Change (as described in the 2027 Indenture), they may be eligible to receive 
a make-whole premium through an increase to the conversion rate up to a maximum of 20.0000 shares per 
$1,000 principal amount of 2027 Notes (subject to other adjustments as described in the 2027 Indenture). 

In  accounting  for  the  issuance  of  the  2027  Notes,  the  Company  determined  that  the  scope 
exceptions provided under ASC Topic 815-40, Derivatives and Hedging – Contracts in Entity’s Own Equity 
(“ASC 815-40”) apply to all but one of the conversion features embedded in the 2027 Notes. This remaining 
conversion feature, which is associated with a Fundamental Change of the Company, was determined to 
have a de minimis value as of December 31, 2023, and 2022. 

The initial purchasers’ fees and the Company’s issuance costs related to the 2027 Notes totaled $8.8 
million, which were recorded as a reduction to the 2027 Notes on the consolidated balance sheet. The $8.8 
million of debt issuance costs is being amortized and recognized as additional interest expense over the 
five-year contractual term of the 2027 Notes using an effective interest rate of 6.2%. 

2023 Convertible Notes 

In  2016,  the  Company  issued  $325  million  aggregate  principal  amount  of  convertible  senior 
unsecured  notes  that  matured  on  February  1,  2023  (the  “2023  Notes”).  The  2023  Notes  were  senior 
unsecured  debt  obligations  and  were  issued  at  par.  On  January  31,  2023,  the  Company  funded  the 
outstanding principal amount of $325 million on the 2023 Notes, due February 1, 2023 and the indenture 

F-35 

 
 
 
 
 
 
 
governing  the  2023  Notes  was  subsequently  satisfied  and  discharged  in  accordance  with  its  terms.  The 
Company’s related “capped call transactions” expired by their terms on January 27, 2023. The Company 
repaid the outstanding principal amount of $325 million together with accrued but unpaid interest on the 
maturity date. The repayment was funded by the issuance of the 2027 Notes and the concurrent common 
stock offering, as well as cash on hand. 

The 2023 Notes were issued pursuant to an indenture dated January 29, 2016 (the “2023 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 2023 Notes bore cash interest at a 
rate of 3.75%, payable on February 1 and August 1 of each year. The 2023 Notes were not redeemable 
prior  to  maturity  and  were  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 2023 Indenture, 
the 2023 Notes were 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 2023 Notes. This represents 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 2023 Notes may have required the Company to repurchase the 2023 Notes 
at par value plus accrued and unpaid interest following the occurrence of a Fundamental Change (as 
described in the 2023 Indenture). If a holder of the 2023 Notes converted upon a Make-Whole Adjustment 
Event (as described in the 2023 Indenture), they may have been 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 2023 Notes (subject to other adjustments as described in the 2023 Indenture). 

The 2023 Notes are accounted for in accordance with ASC 470-20, Debt with Conversion and Other 
Options  (“ASC  470-20”)  and  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 2023 Notes did contain embedded features indexed to its own stock, but 
did 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 met the equity scope exception from 
derivative accounting, and also since the embedded conversion option did not need to be separately 
accounted for as an equity component under ASC 470-20, the proceeds received from the issuance of the 
convertible debt were recorded as a liability on the consolidated balance sheets. 

In connection with the issuance of the 2023 Notes, the Company also paid $38.5 million, including 
expenses, to enter into privately negotiated capped call transactions with certain financial institutions (the 
“capped call transactions”). The capped call transactions expired by their terms on January 27, 2023. The 
capped call transactions were generally expected to reduce the potential dilution upon conversion of the 
2023 Notes in the event that the market price per share of the Company’s common stock, as measured 
under  the  terms  of  the  capped  call  transactions,  was  greater  than  the  strike  price  of  the  capped  call 
transactions, which initially corresponded to the conversion price of the 2023 Notes, and was subject to 
anti-dilution adjustments generally similar to those applicable to the conversion rate of the 2023 Notes. The 
cap price of the capped call transactions was initially $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  was  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, exceeded the cap price, there would nevertheless have been 
dilution upon conversion of the 2023 Notes to the extent that such market price exceeded the cap price. 
The Company evaluated the capped call transactions under ASC Topic 815-10, Derivatives and Hedging – 
Overall and determined that they should be accounted for as a separate transaction and that the capped 
call transactions would be classified as an equity instrument. 

The  Company  incurred  approximately  $10  million  of  debt  issuance  costs  in  2016  relating  to  the 
issuance of the 2023 Notes, which were recorded as a reduction to the 2023 Notes on the consolidated 
balance sheet. The $10.0 million of debt issuance costs was amortized and recognized as additional interest 

F-36 

 
 
 
 
expense  over  the  seven-year  contractual  term  of  the  2023  Notes  on  a  straight-line  basis,  which 
approximated  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. 

Note 11 – Stockholders’ Deficit 

In August 2023, the Company entered into an At Market Issuance Sales Agreement (the "August 
2023 Sales Agreement"), which allows it to issue and sell up to $500 million in gross proceeds of shares of its 
common stock, and terminated its then-existing At Market Issuance Sales agreement entered in June 2021 
(the “June 2021 Sales Agreement”). During the year ended December 31, 2023, the Company sold 38.3 
million  shares  of  its  common  stock  under  its  August  2023  Sales  Agreement  and  7.9  million  shares  of  its 
common stock under its June 2021 Sales Agreement, resulting in net proceeds of approximately $321 million, 
of which $6.9 million was included in Prepaid expenses and other current assets as of December 31, 2023 
and received in cash in January 2024. As of December 31, 2023, the remaining balance available under 
the August 2023 Sales Agreement was approximately $242 million. 

During the year ended December 31, 2022, the Company sold 2.2 million shares of its common stock 

resulting in net proceeds of approximately $179 million, under its June 2021 Sales Agreement.  

In August 2023, pursuant to the Securities Subscription Agreement with SK, the Company agreed to 
sell and issue to SK 6.5 million shares of the Company’s common stock at a price of $13.00 per share (the 
“Shares”) in a Private Placement for aggregate gross proceeds to the Company of approximately $84.5 
million. The Company recognized the Shares at the settlement date fair value of $46.5 million (see Note 4 
for  additional  discussion  of  the  Securities  Subscription  Agreement  with  SK).  The  closing  of  the  Private 
Placement occurred on August 10, 2023. 

In December 2022, the Company completed a public offering of 7,475,000 shares of its common 
stock, including 975,000 shares of common stock that were issued upon the exercise in full of the option to 
purchase  additional  shares  granted  to  the  underwriters,  at  a  price  of  $10.00  per  share  resulting  in  net 
proceeds, net of offering costs of $4.9 million, of approximately $70 million. The Company completed this 
public offering concurrent with the issuance of the 2027 Notes (see Note 10). 

Note 12 – Stock-Based Compensation 

Equity Plans 

In January 2023, the Company established the 2023 Inducement Plan (the “2023 Inducement Plan”), 
which provides for the granting of share-based awards to individuals who were not previously employees, 
or following a bona fide period of non-employment, as an inducement material to such individuals entering 
into employment with the Company. The Company reserved 1.0 million shares of common stock for grants 
under  the  2023  Inducement  Plan.  As  of  December  31,  2023,  there  were  0.2  million  shares  available  for 
issuance under the 2023 Inducement Plan. 

The 2015 Stock Incentive Plan, as amended (“2015 Plan”), was approved at the Company’s annual 
meeting  of  stockholders  in  June  2015.  Under  the  2015  Plan,  equity  awards  may  be  granted  to  officers, 
directors, employees, and consultants of and advisors to the Company and any present or future subsidiary. 

The 2015 Plan authorizes the issuance of up to 21.0 million shares of common stock under equity 
awards granted under the 2015 Plan, which includes an increase of 6.2 million shares approved for issuance 
under the 2015 Plan at the Company’s 2023 annual meeting of stockholders. All such shares authorized for 
issuance  under  the  2015  Plan  have  been  reserved.  The  2015  Plan  will  expire  on  March  30,  2033.  As  of 
December 31, 2023, there were 6.9 million shares available for issuance under the 2015 Plan. 

The Amended and Restated 2005 Stock Incentive Plan (“2005 Plan”) expired in February 2015 and 
no  new  awards  may  be  made  under  such  plan,  although  awards  will  continue  to  be  outstanding  in 
accordance with their terms. 

F-37 

 
 
 
 
 
 
 
 
 
 
 
The 2015 Plan permits and the 2005 Plan permitted the grant of stock options (including incentive 
stock options), restricted stock, SARs, and RSUs. In addition, under the 2015 Plan, unrestricted stock, stock 
units, and performance awards may be granted. Stock options and SARs generally have a maximum term 
of ten years and may be or were granted with an exercise price that is no less than 100% of the fair market 
value of the Company’s common stock at the time of grant. Grants of stock options are generally subject 
to vesting over periods ranging from one to four years. 

The  Company  recorded  stock-based  compensation  expense  in  the  consolidated  statements  of

During the year ended December 31, 2023 and 2022, total stock-based compensation capitalized 
in inventory was $0.5 million and $1.7 million, respectively. No stock-based compensation was capitalized 
in inventory during the year ended December 31, 2021.  

As  of  December  31,  2023,  there  was  approximately  $81.4  million  of  total  unrecognized 
compensation expense related to unvested stock options, SARs, RSUs, and the ESPP. This unrecognized non-
cash  compensation  expense  is  expected  to  be  recognized  over  a  weighted-average  period  of 
approximately  1.0  year  and  will  be  allocated  between  cost  of  sales,  research  and  development,  and 
general  and  administrative  expenses  accordingly.  This  estimate  does  not  include  the  impact  of  other 
possible stock-based awards that may be made during future periods. 

The  aggregate  intrinsic  value  represents  the  total  intrinsic  value  (the  difference  between  the 
Company’s closing stock price on the last trading day of the period and the exercise price, multiplied by

The ESPP was approved at the Company’s annual meeting of stockholders in June 2013. The ESPP 
currently  authorizes  an  aggregate  of  1.2  million  shares  of  common  stock  to  be  purchased,  and  the 
aggregate  amount  of  shares  will  continue  to  increase  5%  on  each  anniversary  of  its  adoption  up  to  a 
maximum of 1.65 million shares. The ESPP allows employees to purchase shares of common stock of the 
Company  at  each  purchase  date  through  payroll  deductions  of  up  to  a  maximum  of  15%  of  their 
compensation, at 85% of the lesser of the market price of the shares at the time of purchase or the market 
price on the beginning date of an option period (or, if later, the date during the option period when the 
employee was first eligible to participate). At December 31, 2023, there were 0.5 million shares available for 
issuance under the ESPP.

As of December 31, 2023, the Company has available federal and state net operating losses of $2.4 
billion,  $877.6 million,  respectively,  that  may  be applied  against  future  taxable  income in  the respective 
jurisdiction. The federal net operating losses of $2.4 billion can be carried forward indefinitely, with all but 
$11.3 million, which expires in 2037, limited to 80% of annual taxable income. State net operating losses of 
$457.4 million  have  various  expiration  dates  between  2028 and 2042.  The  remaining  state  net  operating 
losses of $420.2 million can be carried forward indefinitely. The Company also has research tax credits of 
$51.9 million that will begin to expire in 2024 through 2043 and a foreign tax credit carryforward of $18.7 
million  that  will  expire  in  2030.  Utilization  of  the  federal  and  state  net  operating  loss  carryforwards  and 
research  tax  credits  may  be  subject  to  an  annual  limitation  due  to  potential  ownership  changes  of  the 
Company. As of December 31, 2023, the Company does not expect such limitation, if any, to impact the 
use of its net operating losses and research tax credits. 

The Company files income tax returns in the U.S. federal jurisdiction and in various states, as well as 
in multiple foreign jurisdictions including Sweden and the Czech Republic. The Company has U.S. federal 
and state net operating losses and credit carryforwards that are subject to examination from 2003 through 
2023.  The  returns  in  Sweden  are  subject  to  examination  from  2016  through  2023  and  the  returns  for  the 
Czech Republic are subject to examination from 2019 through 2023.

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, 2023 
and  2022.  The  valuation  allowance  increased  by  $108.8  million  and  $4.8  million  for  the  years  ended 
December 31, 2023 and 2022, respectively. 

The net deferred tax liability of $2.0 million at December 31, 2023 is included within other non-current 

liabilities on the accompanying consolidated balance sheet.

The Company recognizes the effect of an income tax position when it is more likely than not, based 
on the technical merits, that the income 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, 2023,

The Company’s policy is to recognize interest and penalties related to income tax matters in income 
tax expense. As of December 31, 2023 and 2022, the Company had no accruals for interest or penalties. 
The total amount of unrecognized tax benefits that, if recognized, could affect the effective tax rate was 
$4.2  million  and  $5.2  million  as  of  December  31,  2023  and  2022,  respectively.  However,  the  Company 
maintains  a  full  valuation  allowance  as  of  December  31,  2023  and  2022  and  the  recognition  of  any 
unrecognized tax benefits would be offset with a change in the valuation allowance and therefore there 
would  be  no  income  statement  impact.  As  of  December  31,  2023,  the  Company  does  not  expect  a 
significant  change  in  the  recorded  unrecognized  tax  benefits  liability  balance  during  the  next  twelve 
months.  The  unrecognized  tax  benefits  are  presented  in  the  financial  statements  as  a  reduction  to  the 
deferred tax assets for all periods. 

In  2021  the  Organization  for  Economic  Cooperation  and  Development  (“OECD”)  developed 
guidance on Base Erosion and Profit Shifting (“BEPS”) Pillar Two Model Rules (“Pillar Two”), which addresses 
corporate tax planning strategies used by some large multinational corporations to shift profits from higher-
tax jurisdictions to lower-tax jurisdictions or zero-tax locations. This guidance imposes a 15% minimum tax on 
the  earnings  of  large  multinational  corporations.  Pillar  Two  is  expected  to  be  effective  in  2024  for  the 
jurisdictions in which the Company operates. The Company is currently evaluating the application of Pillar 
Two and does not expect these rules to have a significant impact on its effective tax rate or its consolidated 
financial statements.

Legal Matters 

Stockholder Litigation 

On November 12, 2021, Sothinathan Sinnathurai filed a purported securities class action in the U.S. 
District  Court  for  the  District  of  Maryland  (the  “Maryland  Court”)  against  the  Company  and  certain 
members of senior management, captioned Sothinathan Sinnathurai v. Novavax, Inc., et al., No. 8:21-cv-
02910-TDC  (the  “Sinnathurai  Action”).  On  January  26,  2022,  the  Maryland  Court  entered  an  order 
designating David Truong, Nuggehalli Balmukund Nandkumar, and Jeffrey Gabbert as co-lead plaintiffs in 
the Sinnathurai Action. The co-lead plaintiffs filed a consolidated amended complaint on March 11, 2022, 
alleging that the defendants made certain purportedly false and misleading statements concerning the 
Company’s ability to manufacture prototype vaccine on a commercial scale and to secure the prototype 
vaccine’s regulatory approval. The amended complaint defines the purported class as those stockholders 
who purchased the Company’s securities between February 24, 2021 and October 19, 2021. On April 25, 
2022, the defendants filed a motion to dismiss the consolidated amended complaint. On December 12, 
2022, the Maryland Court issued a ruling granting in part and denying in part defendants’ motion to dismiss. 
The Maryland Court dismissed all claims against two individual defendants and claims based on certain 
public statements challenged in the consolidated amended complaint. The Maryland Court denied the 

F-44 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
motion  to  dismiss  as  to  the  remaining  claims  and  defendants,  and  directed  the  Company  and  other 
remaining defendants to answer within fourteen days. On December 27, 2022, the Company filed its answer 
and  affirmative  defenses.  On  March  16,  2023,  the  plaintiffs  filed  a  motion  for  class  certification  and  to 
appoint class representatives and counsel. Due to the Maryland Court’s ruling on the dismissal motion, the 
motion sought to certify a class of stockholders who purchased the Company’s securities between May 11, 
2021, and October 19, 2021. The Company filed its opposition to the plaintiffs’ motion on September 22, 
2023.  On  December  4,  2023,  the  parties  agreed  to  a  binding  settlement  in  principle  (the  “Proposed 
Settlement”) to fully resolve the surviving claims in the Sinnathurai Action. Under the Proposed Settlement’s 
terms,  the  Company  agreed  to  pay  $47  million  into  a  settlement  fund,  which  will  be  funded  by  the 
Company’s directors and officers’ liability insurance and paid to members of a putative settlement class. 
On  January  12,  2024,  after  the  parties  negotiated  and  executed  a  written  agreement  governing  the 
Proposed  Settlement,  plaintiffs  filed  an  unopposed  motion  for  the  Proposed  Settlement’s  preliminary 
approval. On January 23, 2024, the Maryland Court granted the motion for preliminary approval and, as 
requested by the parties, preliminarily certified, for the purposes of settlement only, the settlement class. The 
court also scheduled a settlement hearing to consider final approval of the settlement for May 23, 2024. 

After  the  Sinnathurai  Action  was  filed,  eight  derivative  lawsuits  were  filed:  (i)  Robert  E.  Meyer  v. 
Stanley C. Erck, et al., No. 8:21-cv-02996-TDC (the “Meyer Action”), (ii) Shui Shing Yung v. Stanley C. Erck, et 
al., No. 8:21-cv-03248-TDC (the “Yung Action”), (iii) William Kirst, et al. v. Stanley C. Erck, et al., No. C-15-CV-
21-000618 (the “Kirst Action”), (iv) Amy Snyder v. Stanley C. Erck, et al., No. 8:22-cv-01415-TDC (the “Snyder 
Action”), (v) Charles R. Blackburn, et al. v. Stanley C. Erck, et al., No. 1:22-cv-01417-TDC (the “Blackburn 
Action”), (vi) Diego J. Mesa v. Stanley C. Erck, et al., No. 2022-0770-NAC (the “Mesa Action”), (vii) Sean 
Acosta v. Stanley C. Erck, et al., No. 2022-1133-NAC (the “Acosta Action”), and (viii) Jared Needelman v. 
Stanley C. Erck, et al., No. C-15-CV-23-001550 (the “Needelman Action”). The Meyer, Yung, Snyder, and 
Blackburn Actions were filed in the Maryland Court. The Kirst and Needelman Actions were filed in the Circuit 
Court for Montgomery County, Maryland. The Mesa and Acosta Actions were filed in the Delaware Court 
of Chancery (the “Delaware Court”). The derivative lawsuits name members of the Company’s board of 
directors and certain members of senior management as defendants. The Company is deemed a nominal 
defendant.  The  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. 

On  February  7,  2022,  the  Maryland  Court  entered  an  order  consolidating  the  Meyer  and  Yung 
Actions (the “First Consolidated Derivative Action”). The plaintiffs in the First Consolidated Derivative Action 
filed their consolidated derivative complaint on April 25, 2022. On May 10, 2022, the Maryland Court entered 
an order granting the parties’ request to stay all proceedings and deadlines pending the earlier of dismissal 
or the filing of an answer in the Sinnathurai Action. On June 10, 2022, the Snyder and Blackburn Actions 
were filed. On October 5, 2022, the Maryland Court entered an order granting a request by the plaintiffs in 
the  First  Consolidated  Derivative  Action  and  the  Snyder  and  Blackburn  Actions  to  consolidate  all  three 
actions  and  appoint  co-lead  plaintiffs  and  co-lead  and  liaison  counsel  (the  “Second  Consolidated 
Derivative Action”). The co-lead plaintiffs in the Second Consolidated Derivative Action filed a consolidated 
amended complaint on November 21, 2022. On February 10, 2023, defendants filed a motion to dismiss the 
Second Consolidated Derivative Action. The plaintiffs filed their opposition to the motion to dismiss on April 
11, 2023. Defendants filed their reply brief in further support of their motion to dismiss on May 11, 2023. On 
August 21, 2023, the court entered an order granting in part and denying in part the motion to dismiss; the 
court allowed claims for alleged insider selling under Brophy v. Cities Service Co., et al., 70 A.2d 5 (Del. Ch. 
1949)  and  unjust  enrichment  claims  to  proceed,  but  dismissed  the  remaining  claims  in  the  second 
consolidated  amended  complaint.  On  September  5,  2023,  the  Company  filed  an  Answer  to  the 
consolidated  amended  complaint.  On  September  6,  2023,  the  court  entered  an  order  granting  the 
individual defendants an extension of time to file their answer until November 6, 2023. On October 6, 2023, 
the  Board  of  Directors  of  the  Company  formed  a  Special  Litigation  Committee  (“SLC”)  with  full  and 
exclusive power and authority of the Board to, among other things, investigate, review, and analyze the 
facts and circumstances surrounding the claims asserted in the pending derivative actions, including the 
claims  that  remain  following  the  court’s  order  on  the  motion  to  dismiss  in  the  Second  Consolidated 

F-45 

 
 
Derivative Action. On November 7, 2023, the court entered an order granting the parties’ request to stay 
the Second Consolidated Derivative Action for up to six months from the date of entry of the order. This 
includes  staying  the  deadline  for  the  individual  defendants  to  respond  to  the  consolidated  amended 
complaint. 

The  Kirst  Action  was  filed  on  December  28,  2021,  and  the  defendants  immediately  removed  the 
case to the Maryland Court. On July 21, 2022, the Maryland Court issued a memorandum opinion and order 
remanding the Kirst Action to state court. The plaintiffs filed an amended complaint on December 30, 2022. 
On January 23, 2023, defendants filed a motion to stay the Kirst action. On February 22, 2023, the parties in 
the Kirst Action filed for the Court’s approval of a stipulation staying the Kirst Action pending the resolution 
of defendants’ motion to dismiss in the Second Consolidated Derivative Action. On March 22, 2023, the 
Court entered the parties’ stipulated stay of the Kirst Action pending resolution of the motion to dismiss in 
the Second Consolidated Derivative Action. 

On August 30, 2022, the Mesa Action was filed. On October 3, 2022, the Delaware Court entered 
an order granting the parties’ request to stay all proceedings and deadlines in the Mesa Action pending 
the earlier of dismissal of the Sinnathurai Action or the filing of an answer to the operative complaint in the 
Sinnathurai Action. On January 18, 2023, defendants filed a motion to stay the Mesa Action pending a final 
judgment  in  the  Second  Consolidated  Derivative  Action.  The  plaintiff  filed  his  opposition  on  February  8, 
2023.  Defendants  filed  their  reply  on  February  22,  2023.  On  February  28,  2023,  the  court  granted  the 
defendants’ motion to stay. On August 31, 2023, the plaintiff filed a motion to lift the stay. On October 6, 
2023, the Company filed an opposition to plaintiff’s motion to lift the stay. Plaintiff filed his reply on October 
17, 2023. On December 27, 2023, the parties filed a letter informing the Court that the Second Consolidated 
Derivative  Action  had  been  stayed  for  a  period  of  six  months  and  asked  the  Court  to  stay  further 
proceedings in the Mesa Action until expiration of that stay. 

On  December  7,  2022,  the  Acosta  Action  was  filed.  On  February  6,  2023,  defendants  accepted 
service of the complaint and summons in the Acosta Action. On March 9, 2023, the court entered an order 
granting  the  parties’  request  to  stay  the  Acosta  Action  pending  the  entry  of  a  final,  non-appealable 
judgment in the Second Consolidated Derivative Action. On October 13, 2023, the parties filed, and the 
Delaware Court entered, a stipulated order providing that (i) if the Delaware Court declines to lift the stay 
in the Mesa Action, the Acosta Action will also remain stayed, and (ii) if the Delaware Court lifts the stay in 
the Mesa Action, the stay in the Acosta Action will also be lifted. 

On April 17, 2023, the Needelman Action was filed. On July 12, 2023, the parties filed a stipulation 
and proposed order to stay the Needelman Action pending the Maryland Court’s decision on the motion 
to dismiss in the Second Consolidated Derivative Action. The court entered that order on July 17, 2023. The 
parties continue to discuss next steps in the litigation following the Maryland Court’s ruling on the motion to 
dismiss the Second Consolidated Derivative Action. The court entered that order on July 17, 2023. 

On November 30, 2023, the court entered an order consolidating the Kirst and Needelman Actions. 
On  December  14,  2023,  the  parties  filed  a  stipulation  (i)  extending  the  plaintiffs’  deadline  to  file  a 
consolidated complaint until January 29, 2024, and (ii) otherwise staying all other proceedings in the case 
(including the defendants’ deadline to respond to the consolidated complaint) until February 12, 2024. The 
stipulation entered by the court instructs the parties to discuss whether the stay should be further extended 
in light of the then-current status of the SLC’s investigation. The financial impact of the derivative claims is 
not estimable. 

On November 18, 2022, the Company delivered written notice to Gavi to terminate the Gavi APA 
based  on  Gavi’s  failure  to  procure  the  purchase  of  350  million  doses  of  prototype  vaccine  from  the 
Company as required by the Gavi APA. As of November 18, 2022, the Company had only received orders 
under the Gavi APA for approximately 2 million doses. On December 2, 2022, Gavi issued a written notice 
purporting  to  terminate  the  Gavi  APA  based  on  Gavi’s  contention  that  the  Company  repudiated  the 
agreement  and,  therefore,  materially  breached  the  Gavi  APA.  Gavi  also  contended  that,  based  on  its 
purported termination of the Gavi APA, it was entitled to a refund of the Advance Payment Amount less 
any amounts that have been credited against the purchase price for binding orders placed by a buyer 

F-46 

 
 
 
 
 
 
participating  in  the  COVAX  Facility.  Since  December  31,  2022,  the  remaining  Gavi  Advance  Payment 
Amount, which is $696.4 million as of December 31, 2023, pending resolution of the dispute with Gavi related 
to a return of the remaining Advance Payment Amount, has been classified within Other current liabilities 
in the Company’s consolidated balance sheet. On January 24, 2023, Gavi filed a demand for arbitration 
with  the  International  Court  of  Arbitration  based  on  the  claims  described  above.  The  Company  filed  its 
Answer  and  Counterclaims  on  March  2,  2023.  On  April  5,  2023,  Gavi  filed  its  Reply  to  the  Company’s 
Counterclaims. On February 16, 2024, the Company and Gavi entered into a Termination and Settlement 
Agreement  (the  “Gavi  Settlement  Agreement”)  terminating  the  Gavi  APA,  settling  the  arbitration 
proceedings and releasing both parties of all claims arising from, under or otherwise in connection with the 
Gavi APA. Pursuant to the Gavi Settlement Agreement, the Company is responsible for payment to Gavi of 
(i)  an  initial  settlement  payment  of  $75  million,  which  the  Company  paid  on  February  20,  2024,  and  (ii) 
deferred  payments,  in  equal  annual  amounts  of  $80  million  payable  each  calendar  year  through  a 
deferred payment term ending December 31, 2028. The deferred payments are due in variable quarterly 
installments beginning in the first quarter of 2024 and total $400 million during the deferred payment term. 
Such deferred payments may be reduced through Gavi’s use of an annual vaccine credit equivalent to 
the unpaid balance of such deferred payments each year, which may be applied to qualifying sales of 
any of the Company’s vaccines funded by Gavi for supply to certain low-income and lower-middle income 
countries. The Company has the right to price the vaccines offered to such low-income and lower-middle 
income countries at its discretion, and, when utilized by Gavi, the Company will credit the actual price per 
vaccine paid against the applicable credit. The Company intends to price vaccines offered via the tender 
process,  consistent  with  its  shared  goal  with  Gavi  to  provide  equitable  access  to  those  countries.  On 
February 22, 2024, the claims and counterclaims were dismissed with prejudice. 

On September 30, 2022, the Company and Fujifilm entered into the Fujifilm Settlement Agreement 
regarding  amounts  due  to  Fujifilm  in  connection  with  the  termination  of  manufacturing  activity  at  FDBT 
under the CSA dated August 20, 2021 and the MSA by and between the Company and Fujifilm. The MSA 
and CSA established the general terms and conditions applicable to Fujifilm’s manufacturing and supply 
activities related to the Company’s prototype vaccine under the associated statements of work. Pursuant 
to the Fujifilm Settlement Agreement, the Company agreed to pay up to $185.0 million (the “Settlement 
Payment”) to Fujifilm in connection with cancellation of manufacturing activity at FDBT. Under the Fujifilm 
Settlement Agreement, the final two quarterly installments due to Fujifilm were subject to Fujifilm’s obligation 
to  use  commercially  reasonable  efforts  to  mitigate  losses  associated  with  the  vacant  manufacturing 
capacity caused by the termination of manufacturing activities at FDBT under the CSA. Any replacement 
revenue achieved by Fujifilm’s mitigation efforts between July 1, 2023 and December 31, 2023 would offset 
the final two settlement payments owed by the Company. On October 2, 2023, the Company sent a notice 
of  breach  under  the  Fujifilm  Settlement  Agreement  to  Fujifilm  setting  forth  the  Company’s  position  that 
Fujifilm  had  not  used  commercially  reasonable  efforts  to  mitigate  losses.  The  Company  withheld  two 
installments  of  $34.3  million  due  to  Fujifilm  on  September  30,  2023  and  December  31,  2023,  pending 
resolution of the issues identified in the notice of breach. On October 30, 2023, FDBT filed a demand for 
arbitration with Judicial Arbitration and Mediation Services (“JAMS”) seeking payment of the third quarter 
installment  of  the  Settlement  Payment.  An  arbitration  hearing  has  been  scheduled  for  May  2024.  As  of 
December 31, 2023, the remaining payment of $68.6 million was reflected in Accrued expenses.  

The  Company  is  also  involved  in  various  other  legal  proceedings  arising  in  the  normal  course  of 
business. Although the outcomes of these other legal proceedings are inherently difficult to predict, the 
Company  does  not  expect  the  resolution  of  these  other  legal  proceedings  to  have  a  material  adverse 
effect on its 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 CDMOs 
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  9).  Certain  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 such obligations are dependent 

F-47 

 
 
 
 
on  the  timing  of  termination  and  the  terms  of  the  relevant  agreement,  and  cannot  be  reasonably 
estimated. As of December 31, 2023, 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, 2023, the 
Company had no non-cancelable purchase commitments with a remaining term of more than one year. 

Note 17 – Restructuring 

As  of  December  31,  2023,  the  restructuring  charge  recorded  by  the  Company  comprised  (in 

thousands):  

Severance and employee benefit costs 

Impairment of assets 
Total Restructuring charge (1) 

Amount 

$ 

$ 
$ 

  4,503 

10,081

(1) Restructuring charges of $0.5 million, $2.3 million and $11.5 million are included in Cost of sales, 
Research and development and Selling, general, and administrative expenses, respectively, in the 
Consolidated Statements of Operations for the period ended December 31, 2023. These charges 
reflect substantially all expected restructuring charges under the Restructuring Plan. 

Severance and employee benefit costs 

Employees affected by the reduction in force under the Restructuring Plan are entitled to receive 
severance  payments  and  certain  termination  benefits.  The  Company  recorded  a  severance  and 
termination benefit cost in full for employees who were notified of their termination during the year ended 
December  31,  2023  and  had  no  requirements  for  future  service.  The  Company  fully  paid  $4.5  million  for 
severance  and  employee  benefit  costs  during  the  year  ended  December  31,  2023  and  no  remaining 
liability for the severance and employee benefit costs is included in the Company’s consolidated balance 
sheet  as  of  December  31,  2023.  There  were  no  severance  and  employee  benefit  costs  during  the  year 
ended December 31, 2022 and 2021. 

Impairment of long-lived assets 

In  connection  with  the  Restructuring  Plan,  the  Company  evaluated  its  long-lived  assets  for 
impairment including certain leased laboratory and office spaces located in Gaithersburg, Maryland. The 
evaluation is subject to judgment and actual results may vary from the estimates, resulting in potential future 
adjustments to amounts recorded. During the year ended December 31, 2023, the Company recorded an 
impairment  charge  of  $10.1  million  related  to  the  impairment  of  long-lived  assets,  including  $5.9  million 
related to ROU assets for facility leases. There were no impairment charges recorded during the year ended 
December 31, 2022 and 2021. 

Note 18 – Subsequent Events 

On  January  31,  2024,  the  Company  announced  that  the  Board  of  Directors  of  the  Company 
approved  an  approximately  12%  reduction  of  its  global  workforce,  comprised  of  an  approximately  9% 
reduction  in  the  Company’s  full-time  employees  and  the  remainder  comprised  of  contractors  and 
consultants.  

On  February  16,  2024,  the  Company  and  Gavi  entered  into  the  Gavi  Settlement  Agreement 
terminating the Gavi APA, settling the arbitration proceedings and releasing both parties of all claims arising 
from, under or otherwise in connection with the Gavi APA. The terms of the Gavi Settlement Agreement are 
outlined in Note 3 and Note 16.
