Overview

Novavax, Inc., together with our wholly-owned subsidiaries, is a biotechnology
company that promotes improved health globally through the discovery,
development, and commercialization of innovative vaccines to prevent serious
infectious diseases. Our proprietary recombinant technology platform harnesses
the power and speed of genetic engineering to efficiently produce highly
immunogenic nanoparticle vaccines designed to address urgent global health
needs.

Our vaccine candidates are genetically engineered nanostructures of
conformationally correct recombinant proteins that mimic those found on natural
pathogens. This technology enables the immune system to recognize the right
target proteins from different angles and develop protective antibodies. We
believe that our vaccine technology may lead to the induction of a
differentiated immune response that may be more efficacious than naturally
occurring immunity or other vaccine approaches. Our vaccine candidates also
incorporate our proprietary saponin-based Matrix-M™ adjuvant to enhance the
immune response and stimulate higher levels of functional antibodies and induce
a cellular immune response.

We have developed a COVID-19 vaccine ("NVX-CoV2373," "Nuvaxovid™," "Covavax™"),
and are developing an influenza vaccine, a COVID-19-Influenza Combination
vaccine ("CIC"), and additional vaccine candidates. NVX-CoV2373 has received
approval, interim authorization, provisional approval, conditional marketing
authorization ("CMA"), and emergency use authorization ("EUA") from multiple
regulatory authorities globally. In addition to COVID-19 and seasonal influenza,
our other areas of focus include respiratory syncytial virus ("RSV") and
malaria.

Technology Overview



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

Recombinant Nanoparticle Vaccine Technology



Once a pathogenic threat has been identified, the genetic sequence encoding the
antigen is selected for subsequent use in developing the vaccine construct. The
genetic sequence may be optimized to enhance protein stability or confer
resistance to degradation. This genetic construct is inserted into the
baculovirus Spodoptera frugiperda ("Sf9/BV") insect cell-expression system,
which enables efficient, large-scale expression of the optimized protein. The
Sf9/BV system produces proteins that are properly folded and modified - which
can be critical for functional, protective immunity - as the vaccine antigen.
Protein antigens are purified and organized around a polysorbate-based
nanoparticle core, in a configuration that resembles their native presentation.
This results in a highly immunogenic nanoparticle that is ready to be formulated
with Matrix-M™ adjuvant.

Matrix-M™ Adjuvant

Our proprietary Matrix-M™ adjuvant has been a key differentiator within our
platform. This adjuvant has demonstrated potent, well-tolerated, and durable
efficacy by stimulating the entry of antigen presenting cells ("APCs") into the
injection site and enhancing antigen presentation in local lymph nodes. This in
turn activates APCs, T-cell and B-cell populations, plasma cells, and high
affinity antibodies, thereby boosting immune response. This potent mechanism of
action enables a lower dose of antigen required to achieve the desired immune
response and we believe thereby contributes to increased vaccine supply and
manufacturing capacity. These immune-boosting and dose-sparing capabilities
contribute to the adjuvant's highly unique profile.

NVX-CoV2373 Regulatory and Licensure



We continue to make progress in advancing NVX-CoV2373 toward regulatory
approvals. We have received numerous authorizations globally for primary series,
and both homologous and heterologous booster indications, which collectively
have the potential to reach over six billion individuals. To date, we have
received approval, interim authorization, provisional approval, CMA, and EUA for
both adult and adolescent populations, and we expect to initiate additional
rolling submissions worldwide. We continue to work closely with governments,
regulatory authorities, and non-governmental organizations in our commitment to
facilitate equitable global access to our COVID-19 vaccine.

For the territories in which our vaccine has gained authorization, NVX-CoV2373
is marketed under the brand names (i) Nuvaxovid™ COVID-19 Vaccine (SARS-CoV-2 rS
[Recombinant, adjuvanted]), (ii) Covovax™ (manufacturing and commercialization
by the Serum Institute of India Pvt. Ltd. ("SIIPL")), or (iii) Novavax' COVID-19
Vaccine, Adjuvanted.

Clinical Pipeline

Our clinical pipeline encompasses vaccine candidates spanning multiple
therapeutic areas including coronavirus, seasonal influenza, RSV, and Matrix-MTM
adjuvant collaborations for the prevention of malaria. Our COVID-19 vaccine
candidate, NVX-CoV2373, is our leading product, having received approval,
interim authorization, provisional approval, CMA, and EUA from multiple
regulatory authorities globally. We advanced NVX-CoV2373 through two pivotal
Phase 3 clinical trials that demonstrated high efficacy against both the
original COVID-19 strain and commonly circulating COVID-19 variants of concern
("VoC"), while maintaining a favorable safety profile. We also advanced our
influenza vaccine through a Phase 3 clinical trial, which demonstrated positive
top-line results and achieved statistical significance in key secondary
endpoints. We initiated a trial of a CIC consisting of our influenza vaccine and
NVX-CoV2373. In April 2022, we announced initial results from Phase 1/2 clinical
trial of CIC demonstrating that formulating the combination vaccine is
well-tolerated and immunogenic. Modeling results showed that combined
formulation has the potential to reduce total antigen amount by up to 50%
overall, optimizing production and delivery. Additionally, we remain interested
in further development of our RSV Program for respiratory syncytial virus fusion
(F) protein nanoparticle vaccine candidate ("RSV F Vaccine"). Ongoing Phase 3
trials are being conducted by our partner, Jenner Institute, University of
Oxford, for R21, a malaria candidate currently under development by the
University of Oxford in partnership with SIIPL, which is formulated using our
Matrix-M™ adjuvant.

We remain focused on bringing our NVX-CoV2373 vaccine candidate to market
following global regulatory authorizations. Through ongoing booster studies in
our clinical trials, as well as the development of COVID-19 variant strain
vaccine candidates, we continue to collect data to characterize and improve
vaccine performance. In April 2022, we announced the initiation of a Phase 3
COVID-19 vaccine booster study in adolescents ages 12-17 years as part of our
PREVENT-19 trial, and in May 2022, we announced our participation in University
of Oxford's Com-COV3 booster trial of COVID-19 vaccines in adolescents ages
12-15 years. Additionally, in May 2022, we announced the initiation of a Phase 3
clinical trial for use of our Omicron variant strain vaccine as a booster. We
remain in close collaboration with regulatory authorities for providing
additional variant data. We expect to leverage these clinical insights to
advance the use and additional regulatory approvals of our COVID-19 vaccine for
primary, booster, and pediatric indications globally, amidst the ongoing and
evolving COVID-19 pandemic.

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

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 (unaudited) and the accompanying notes, which have been prepared in accordance with generally accepted accounting principles in the United States.


                                       23
--------------------------------------------------------------------------------
  Table of Contents
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 at
the date of the financial statements and the reported amounts of revenue and
expenses during the reporting period. Our critical accounting policies and
estimates are included under Item 7 of our Annual Report on Form 10-K for the
fiscal year ended December 31, 2021, as filed with the SEC, and are updated for
inventory valuation below.

Inventory Valuation

We periodically analyze our inventories for excess amounts or obsolescence and
write down obsolete or otherwise unmarketable inventory to its estimated net
realizable value based on assumptions about expected future demand and market
conditions. 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. Expense incurred related to excess inventory
and obsolete inventory is recorded as a component of cost of sales in the
consolidated statement of operations.

Recent Accounting Pronouncements Not Yet Adopted

Results of Operations

The following is a discussion of the historical financial condition and results of our operations that should be read in conjunction with the unaudited consolidated financial statements and notes set forth in this Quarterly Report.

Three Months Ended June 30, 2022 and 2021



Revenue
                                  Three Months Ended June 30,

Royalties and other           22,696         25,528          (2,832)
Total revenue              $ 185,925      $ 298,017      $ (112,092)


Revenue for the three months ended June 30, 2022 was $185.9 million as compared
to $298.0 million for the same period in 2021, a decrease of $112.1 million.
Revenue for the three months ended June 30, 2022 was primarily comprised of
revenue for services performed under the agreement with the U.S. government
partnership formerly known as OWS ("OWS Agreement") and revenue from product
sales of NVX-CoV2373. Revenue for the three months ended June 30, 2021 was
primarily comprised of revenue for services performed under the OWS Agreement
and our funding agreements with CEPI. The decrease in revenue was due to
decreased development activities under the OWS Agreement as we began commercial
sales of NVX-CoV2373, partially offset by an increase in revenue due to the
commencement of product sales of NVX-CoV2373.

We expect revenue in 2022 to significantly increase as compared to 2021 due to
product sales of NVX-CoV2373 under various supply agreements, sometimes referred
to as advance purchase agreements ("APAs"), as a result of multiple global
regulatory approvals. Certain revenue from product sales of NVX-CoV2373 that was
originally planned for the three months ended June 30, 2022 is now planned for
the second half of 2022 based on requested and revised customer delivery plans.
Revenue in 2022 is also expected to increase due to royalties from the sale of
NVX-CoV2373 under our supply and license agreements with strategic partners to
supply NVX-CoV2373 in their specified territories where we are entitled to
receive royalties from such sales, and our NVX-CoV2373 program, which we
anticipate will continue to be funded by OWS and other revenue sources.

Cost of Sales

Cost of sales was $271.1 million, or 489% of product sales, for the three months
ended June 30, 2022, including expense of $255.3 million related to excess,
obsolete, or expired inventory and losses on firm purchase commitments. Prior to
receiving regulatory approval, we expensed manufacturing costs as research and
development expenses. After receiving regulatory approval, we capitalize the
costs of production for a particular supply chain when we determine that we have
a present right to the economic benefit associated with the product. While we
tracked the quantities of our manufactured vaccine product and components, we
did not track pre-approval manufacturing costs and therefore the manufacturing
cost of our pre-launch inventory produced prior to approval is not reasonably
determinable. However, based on our expectations for future manufacturing costs
to produce our vaccine product and components inventory, we estimate at June 30,
2022 we had approximately $0.3 billion of commercial inventory that was expensed
prior to approval. We expect to utilize all of our reduced-cost inventory during
2022. If inventory sold for the three months ended June 30, 2022 was valued at
expected standard cost, including expenses related to excess and obsolete
inventory, adjusted cost of sales for the period would have been approximately
$279.5 million, or 504% of product sales, an adjustment of $8.4 million as
compared to cost of sales recognized. The cost of sales to high income countries
is expected to be between 15% and 30% of product sales based on our standard
cost. 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 $289.6 million for the three
months ended June 30, 2022 as compared to $570.7 million for the three months
ended June 30, 2021, a decrease of $281.0 million primarily due to research and
development of NVX-CoV2373, as summarized in the table below (in thousands):

                                                                    Three Months Ended June 30,

Total research and development expenses                        $      

289,648 $ 570,685




Research and development expenses for NVX-CoV2373 for the three months ended
June 30, 2022 and 2021, included a benefit of $87.2 million related to
previously accelerated manufacturing costs and an expense of $20.0 million
related to the acceleration of manufacturing costs, respectively, for leases
that we determined were embedded in multiple manufacturing supply agreements
with Contract Manufacturing Organizations ("CMOs") and contract manufacturing
and development organizations ("CDMOs"). For 2022, we expect total research and
development expenses to decrease as compared to 2021. The decline in 2022 is
anticipated to result from expected capitalization of manufacturing costs during
2022 that were previously recognized as research and development expenses in
prior periods, partially offset by research and development expenses related to

other programs.

Selling, General, and Administrative Expenses

Selling, general, and administrative expenses increased to $108.2 million for
the three months ended June 30, 2022 from $73.2 million for the same period in
2021, an increase of $35.0 million. The increase in selling, general, and
administrative expenses is primarily due to an increase in professional fees in
support of our NVX-CoV2373 program. For 2022, we expect selling, general, and
administrative expenses to increase significantly as compared to 2021 due to
increased activities related to supporting our NVX-CoV2373 program and increases
in employee-related costs and professional fees.

We had total other expense, net, of $26.1 million for the three months ended
June 30, 2022 as compared to $2.9 million for the same period in 2021. During
the three months ended June 30, 2022 and 2021, other income (expense) included a
loss of $20.1 million and $2.7 million, respectively, incurred by our foreign
subsidiaries, primarily related to the impact of foreign exchange rate
differences on an intercompany loan with Novavax CZ.

Income Tax Expense



During the three months ended June 30, 2022 and 2021, we recognized $1.4 million
and $3.5 million, respectively, of income tax expense related to federal and
state income taxes and foreign withholding tax on royalties.

Net loss for the three months ended June 30, 2022 was $510.5 million, or $6.53
per share, basic, as compared to a net loss of $352.3 million, or $4.75 per
share, basic, for the same period in 2021. The change in net loss during the
three months ended June 30, 2022, was primarily due to decreased revenue under
the OWS Agreement and the write-down of excess, obsolete, or expired inventory
and losses on firm purchase commitments, partially offset by revenue from
commercial sales of NVX-CoV2373 and a decrease in research and development
expense.

The increase in weighted average shares outstanding for the three months ended
June 30, 2022 is primarily a result of sales of our common stock and exercises
of stock-based awards in 2022 and 2021.

Revenue for the six months ended June 30, 2022 was $889.9 million as compared to
$745.2 million for the same period in 2021, an increase of $144.7 million.
Revenue for the six months ended June 30, 2022 was primarily comprised of
revenue from product sales of NVX-CoV2373 and, to a lesser extent, revenue for
services performed under the OWS Agreement. Revenue for the six months ended
June 30, 2021 was primarily comprised of revenue for services performed under
the OWS Agreement and our funding agreements with CEPI. The increase in revenue
was due to the commencement of product sales of NVX-CoV2373 and, to a lesser
extent, royalties under our licensing arrangements, partially offset by
decreased development activities under the OWS Agreement and our funding
agreements with CEPI as we began commercial sales of NVX-CoV2373.

Cost of Sales

Cost of sales was $286.3 million, or 45% of product sales, for the six months
ended June 30, 2022, including expense of $255.3 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. However,
based on our expectations for future manufacturing costs to produce our vaccine
product and components inventory, we estimate at June 30, 2022 we had
approximately $0.3 billion of commercial inventory that was expensed prior to
approval. We expect to utilize all of our reduced-cost inventory during 2022. If
inventory sold for the six months ended June 30, 2022 was valued at expected
standard cost, adjusted cost of sales for the period would have been
approximately $439.5 million, or 69% of product sales, an adjustment of
$153.2 million as compared to cost of sales recognized. The cost of sales to
high income countries is expected to be between 15% and 30% of product sales
based on our standard cost. 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 decreased to $673.1 million for the six months
ended June 30, 2022 from $1.2 billion for the same period in 2021, a decrease of
$490.2 million, primarily due to decreased development activities relating to
NVX-CoV2373, as summarized in the table below (in thousands):
                                                                      Six Months Ended June 30,

Research and development expenses for NVX-CoV2373 for the six months ended
June 30, 2022 and 2021, included a benefit of $67.4 million related to
previously accelerated manufacturing costs and an expense of $43.0 million
related to the acceleration of manufacturing costs, respectively, for leases
that we determined were embedded in multiple manufacturing supply agreements
with CMOs and CDMOs.

Selling, General, and Administrative Expenses



Selling, general, and administrative expenses increased to $204.2 million for
the six months ended June 30, 2022 from $136.4 million for the same period in
2021, an increase of $67.8 million. The increase in selling, general, and
administrative expenses is primarily due to an increase in professional fees in
support of our NVX-CoV2373 program.

We had total other expense, net of $29.3 million for the six months ended June
30, 2022 as compared to $14.0 million for the same period in 2021. In the six
months ended June 30, 2022 and 2021, we also recorded interest expense of
$3.4 million and $4.0 million, respectively, for finance leases. During the six
months ended June 30, 2022 and 2021, other income (expense) included a loss of
$21.5 million and $3.9 million, respectively, incurred by our foreign
subsidiaries, primarily related to the impact of foreign exchange rate
differences on an intercompany loan with Novavax CZ.

Income Tax Expense



During the six months ended June 30, 2022 and 2021, we recognized $4.1 million
and $6.6 million, respectively, of income tax expense related to federal and
state income taxes and foreign withholding tax on royalties.

share, as compared to $575.0 million, or $7.82 per share, for the same period in
2021. The change in net loss during the six months ended June 30, 2022 was
primarily due to the commencement of commercial sales of NVX-CoV2373, partially
offset by decreased revenue under the OWS Agreement, and a decrease in research
and development expense, partially offset by the write-down of excess, obsolete,
or expired inventory and losses on firm purchase commitments.

The increase in weighted average shares outstanding for the six months ended
June 30, 2022 is primarily a result of sales of our common stock in 2022 and
2021.

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; funding under our grant agreements;
our projected activities related to the development and commercial support of
NVX-CoV2373 and variant candidates, including significant commitments under
various CRO, CMO, and CDMO agreements; the progress of preclinical studies and
clinical trials; the time and costs involved in obtaining regulatory approvals;
the costs of filing, prosecuting, defending, and enforcing patent claims and
other intellectual property rights; and other manufacturing, sales, and
distribution costs. We plan to continue developing other vaccines and product
candidates, such as our influenza vaccine candidate and potential combination
vaccines candidates, which are in various stages of development.

We have entered into supply agreements, sometimes referred to as APAs, with
Gavi, the Vaccine Alliance ("Gavi"); the European Commission ("EC"); and various
countries globally. We also have grant and license agreements. As of June 30,
2022, the aggregate amount of the transaction price allocated to performance
obligations that were unsatisfied (or partially unsatisfied), excluding amounts
related to sales-based royalties under the license agreements, was approximately
$5 billion. The timing to fulfill performance obligations related to grant
agreements will depend on the results of our research and development
activities, including clinical trials, and delivery of doses. The timing to
fulfill performance obligations related to supply agreements will depend on
timing of product manufacturing, receipt of marketing authorizations 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
NVX-CoV2373 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 NVX-CoV2373. Such upfront payments
under our supply agreements generally become non-refundable upon our achievement
of certain development, regulatory, and commercial milestones. Failure to meet
regulatory milestones, product volume, or delivery timing obligations under our
supply agreements may require us to refund portions of upfront payments or
result in reduced future payments, which could result in a material and adverse
effect on our financial condition. In addition, we continue to assess our
manufacturing needs and intend to modify our global manufacturing footprint
consistent with our contractual obligations to supply, and anticipated demand
for, NVX-CoV2373, and in doing so recognize that significant costs may be
incurred.

Under the terms of our contracted supply commitment with Gavi, which includes
the supply obligation of our licensed partner, SIIPL, 1.1 billion doses of
NVX-CoV2373 are to be made available to countries participating in the COVAX
Facility, which was established to allocate and distribute vaccines equitably to
participating countries and economies. The Novavax portion is a supply agreement
that contemplates that we will manufacture and distribute 350 million doses.
Under that agreement with Gavi, we received an upfront payment of $350 million
from Gavi in 2021 and an additional payment of $350 million in the first quarter
of 2022 related to our achieving WHO Emergency Use Listing. Although Novavax is
prepared to deliver the quantities of NVX-CoV2373 doses to Gavi under the terms
of our supply agreement, we were notified by Gavi of its intent to seek to
revise the number and timing of doses of NVX-CoV2373 supplied by Novavax under
such agreement. Furthermore, Gavi may seek partial or full recovery of the prior
nonrefundable payments it has made to Novavax. Our position is that Gavi has no
contractual right to recover prior nonrefundable payments. To date, Novavax has
not received an order from Gavi and the timing and quantities of future orders
to deliver NVX-CoV2373 to the COVAX facility are unclear.

In July 2022, we entered into an Amended and Restated SARS-CoV-2 Vaccine Supply
Agreement (the "Amended and Restated UK Supply Agreement") with The Secretary of
State for Business, Energy and Industrial Strategy, 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 originally entered into in October 2020 (the "Original UK
Supply Agreement"). Pursuant to the Original UK Supply Agreement, the Authority
agreed to purchase 60 million doses of NVX-CoV2373. Under 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 of NVX-CoV2373, with the
number of additional doses contingent on our timely achievement of supportive
recommendations from the United Kingdom's Joint Committee on Vaccination and
Immunisation (the "JCVI"). In the event that we are unable to achieve the JCVI
supportive recommendations, we may have to repay up to $225.0 million related to
the upfront payment we 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.

We have an APA with the EC acting on behalf of various EU member states to
supply a minimum of 20 million and up to 100 million initial doses of
NVX-CoV2373, with the option for the Commission to purchase an additional 100
million doses up to a maximum aggregate of 200 million doses in one or more
tranches, through 2023. We are in the process of finalizing a revised delivery
schedule for the remaining 42 million doses of the 70 million previously
committed doses under our APA with the EC that were originally scheduled for
delivery during the first and second quarters of 2022. In July and August 2022,
we were notified by the EC that it was cancelling 5 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 65 million doses.

In July 2022, we entered into a modification to the OWS Agreement that amended
the terms of such agreement to provide for (i) an initial delivery to the U.S.
government of approximately 3 million doses of NVX-CoV2373, contingent on the
timing of EUA approval by the FDA, as well as the timing of label language and
artwork approvals by the FDA and the recommendation of the Advisory Committee on
Immunization Practices within the CDC, and (ii) any additional manufacture and
delivery to the U.S. government up to an aggregate of 100 million doses of
NVX-CoV2373 contemplated by the original OWS Agreement (inclusive of the initial
batch of approximately 3 million doses) dependent on U.S. government demand, FDA
guidance on strain selection, agreement between the parties on the price of such
doses, and available funding. Additionally, in July 2022, we entered into a
modification to our existing agreement with the DoD that amended the terms of
such agreement to provide for the initial delivery of 0.2 million doses of
NVX-CoV2373 after receipt of EUA approval from the FDA, with delivery of the
remaining 9.8 million doses of NVX-CoV2373 contemplated by the original
agreement subject to DoD demand and available funding.

In the six months ended June 30, 2022, we primarily funded our operations with
cash and cash equivalents, upfront payments under APAs, revenue from product
sales, royalties under licensing arrangements with our strategic partners, and
proceeds from the sale of common stock together with revenue under the OWS
Agreement that supports our NVX-CoV2373 vaccine development activities. We
anticipate our future operations to be funded by revenue from product sales,
royalties under licensing arrangements with our strategic partners, revenue
under our OWS Agreement, our cash and cash equivalents, and other potential
funding sources.

As of June 30, 2022, we had $1.4 billion in cash and cash equivalents and restricted cash as compared to $1.5 billion as of December 31, 2021.

Net cash used in operating activities was $259.4 million for the six months
ended June 30, 2022, as compared to net cash provided by operating activities of
$807.5 million for the same period in 2021. The decrease in cash provided is
primarily due to the application of upfront payments under APAs resulting from
sales of NVX-CoV2373 during the six months ended June 30, 2022 as compared to an
increase in cash due to the receipt of upfront payments under APAs during the
six months ended June 30, 2021.

During the six months ended June 30, 2022 and 2021, our investing activities
consisted primarily of capital expenditures and maturities and sale of
marketable securities, net of purchases. Capital expenditures for the six months
ended June 30, 2022 and 2021 were $41.4 million and $28.9 million, respectively.
For 2022, we expect our capital expenditures to continue to increase due to
further development activities for our NVX-CoV2373 program, including the
additional build-out of research and development and manufacturing facilities
and related equipment, and the build-out of our new corporate office facility.

Our financing activities consisted primarily of sales of our common stock under
our At Market Issuance Sales Agreements, payments of finance lease liabilities,
and exercise of stock-based awards. In the six months ended June 30, 2022 and
2021, we received net proceeds of approximately $179 million and $565 million,
respectively, from selling shares of common stock through our At Market Issuance
Sales Agreements.
