Overview

Adagio Therapeutics, Inc. is a clinical-stage biopharmaceutical company focused
on the discovery, development and commercialization of differentiated products
for the prevention and treatment of infectious disease. We are developing our
lead product candidate, adintrevimab, for the prevention and treatment of
coronavirus disease 2019, or COVID-19, the disease caused by the virus
SARS-CoV-2 and its variants. COVID-19 has caused the current global pandemic
that remains a significant global health crisis and has resulted in millions of
deaths and lasting health problems in many survivors. We believe that COVID-19
will become an endemic disease requiring a variety of effective, safe and
convenient prevention and treatment options for years to come. We are leveraging
our team's collective expertise and platform to deliver adintrevimab to patients
and to discover novel solutions to infectious diseases through internal research
and collaborations.

Adintrevimab is designed to be a potent, long-acting and broadly neutralizing
antibody for both the prevention and treatment of COVID-19. We believe several
key attributes combine to differentiate adintrevimab, including breadth,
potency, durability of protection, convenient intramuscular, or IM,
administration, and potential for broad application across multiple indications,
depending on the SARS-CoV-2 variant.

Data from our Phase 1 healthy volunteer study ADG20-1-001 confirmed the extended
half-life of adintrevimab, which we believe may allow for durable protection
against COVID-19, depending on the variant. In February 2022, we expanded the
Phase 1 study to evaluate safety and pharmacokinetics at higher doses. As of
March 27, 2022, there were no study drug related adverse events, serious adverse
events, injection-site reactions or hypersensitivity reactions reported across
all dose levels evaluated.

We are assessing adintrevimab in two separate Phase 2/3 clinical trials: our
EVADE trial to evaluate adintrevimab for the prevention of COVID-19 and our
STAMP trial to evaluate adintrevimab for the treatment of COVID-19. Our EVADE
clinical trial is a global Phase 2/3 clinical trial evaluating adintrevimab as a
prevention for COVID-19 in both the post-exposure and pre-exposure settings. Our
STAMP trial is our global Phase 2/3 clinical trial evaluating adintrevimab as a
treatment for COVID-19. Due to the emergence and global spread of the Omicron
variant, against which adintrevimab has reduced in vitro neutralization potency
compared to prior variants, enrollment in both EVADE and STAMP was paused on
January 11, 2022, and preliminary efficacy and safety data were evaluated in
pre-and post-Omicron populations.

In the primary analysis population, patients infected with or exposed to a
non-Omicron variant, or the pre-Omicron group, adintrevimab met the primary
objectives across all three indications, demonstrating statistically significant
and clinically meaningful efficacy. In pre-exposure and post-exposure
prophylaxis, adintrevimab was associated with 71% and 75% relative risk
reductions compared to placebo, respectively, in the prevention of RT-PCR
confirmed symptomatic COVID-19. In an exploratory analysis of patients exposed
to the Omicron variant, or the post-Omicron group, in pre-exposure prophylaxis,
adintrevimab was associated with a clinically meaningful reduction in the risk
of developing RT-PCR confirmed symptomatic COVID-19 compared with placebo. In
treatment, adintrevimab was associated with a 66% relative risk reduction
compared to placebo in the incidence COVID-19 related hospitalization or all
cause death through Day 29 in the pre-Omicron group. In patients treated within
three days of symptom onset, adintrevimab was associated with a reduced risk of
COVID-19 hospitalization or death from any cause through Day 29 by 77% compared
to placebo. A preliminary analysis of available safety data in each trial
revealed a safety profile similar to that of placebo for adintrevimab.

We are also evaluating additional broadly neutralizing antibodies targeting the
receptor binding domain, or RBD, as well as other subdomains within the spike
protein for COVID-19. In addition, we plan to leverage the robust antibody
discovery and development capabilities that have enabled our expedited
advancement of adintrevimab into clinical trials to develop therapeutic or
preventative options for other infectious diseases, such as additional
coronaviruses and influenza. In addition to building a portfolio of broadly
neutralizing antibodies, we are leveraging our knowledge around broadly
neutralizing antibody responses to inform the rational design of coronavirus
vaccine antigens.

SARS-CoV-2 has given rise to a global pandemic that swept rapidly throughout the
world in 2020. Of significant current concern is the continued emergence of a
number of SARS-CoV-2 variants with increased transmissibility, pathogenicity,
and/or the ability to evade neutralizing antibodies. In addition to the
emergence of these variants, there are multiple factors that we

                                      106
--------------------------------------------------------------------------------


believe contribute to the likelihood of COVID-19 becoming an endemic threat,
including: (1) viral transmission before symptom onset; (2) uneven global
rollout of vaccinations; (3) ongoing vaccine hesitancy; (4) limited duration of
immunity conferred by both natural infection and vaccination; (5) limited
vaccine efficacy against certain SARS-CoV-2 variants; (6) uncertain impact of
vaccines on transmission; and (7) variable implementation of virus mitigation
behaviors, such as wearing masks and social distancing. We also believe that
future pandemics similar to the COVID-19 pandemic are likely because, in many
parts of the world, humans live in close proximity to animal species harboring
coronaviruses that are capable of infecting humans.

Our vision is to discover, develop and commercialize differentiated products for
the prevention and treatment of infectious diseases. To enable this vision, our
current discovery efforts are focused on unique antibody-based product
candidates that we optimize to improve breadth, potency, half-life, where
applicable, and developability. Key elements that we believe differentiate our
approach include: (1) recognition of the importance of and identification of
broadly neutralizing antibodies; (2) industry-leading B cell mining, protein
engineering and developability screening capabilities through our internal
expertise and collaborations; and (3) reducing risk of clinical resistance.

We were formed in June 2020. In July 2020, we entered into an assignment and
license agreement, or the Adimab Assignment Agreement, with Adimab, pursuant to
which we acquired certain rights to Adimab's antibodies relating to COVID-19 and
severe acute respiratory syndrome, or SARS, as well as related provisional
patent applications, know-how and data generated with respect to the associated
antibodies. In addition, Adimab granted to us a non-exclusive, worldwide license
to certain of Adimab's platform patents and technology for use in research and
development. In connection with the rights and license acquired, we issued
5,000,000 shares of our Series A preferred stock to Adimab. In May 2021, we
entered into a funded discovery agreement with Adimab focused on discovery
efforts for new antibodies that may be effective against other coronaviruses and
influenza, both of which have the potential to cause pandemics. In the event
that Adimab discovers an antibody that is expected to meet certain product
profiles developed by Adagio, Adagio will have the exclusive option to require
Adimab to assign us its rights in any such antibody and to grant us certain
licenses. In addition, the Company engages third parties, including The Scripps
Research Institute, or TSRI, to perform ongoing research and development and
other services on its behalf.

Since our inception, we have devoted substantially all of our resources to
organizing and staffing, building an intellectual property portfolio, business
planning, conducting research and development, establishing and executing
arrangements with third parties for the manufacture of our product candidates
and raising capital. We rely heavily on external consultants and contract
research organizations, or CROs, to conduct our non-clinical, preclinical and
clinical activities. Additionally, we are currently dependent on WuXi Biologics
(Hong Kong) Limited, or WuXi, a contract development and manufacturing
organization, or CDMO, for the manufacture of our product candidates for
clinical and commercial use. We expect to continue to rely on third parties for
clinical trials and the manufacture and testing of our product candidates.

Since our inception, we have financed our operations with net proceeds of $464.7
million from sales of our preferred stock, and most recently, with net proceeds
from our initial public offering, or IPO. In August 2021, we completed our IPO,
pursuant to which we issued and sold 20,930,000 shares of our common stock,
including 2,730,000 shares of common stock pursuant to the full exercise of the
underwriters' option to purchase additional shares. We received aggregate net
proceeds from our IPO of $327.5 million, after deducting underwriting discounts
and commissions and offering expenses payable by us. To date, we have not
generated any revenue from any sources, including product sales. We have not yet
commenced significant development activities with respect to other product
candidates. Our ability to generate product revenue sufficient to achieve
profitability will depend heavily on the successful development and eventual
commercialization of one or more of our product candidates, if approved.

Since our inception, we have incurred significant losses, including net losses
of $226.8 million and $65.3 million for the year ended December 31, 2021 and the
period from June 3, 2020 (inception) to December 31, 2020, respectively. As of
December 31, 2021, we had an accumulated deficit of $292.1 million. We expect to
continue to incur significant expenses and recognize losses in the foreseeable
future as we expand and progress our research and development activities as well
as the associated manufacturing activities and commercialization efforts. In
addition, our losses from operations may fluctuate significantly from period to
period depending on the timing of our clinical trials and our expenditures on
other research and development activities, including any associated
manufacturing activities, and potential commercialization efforts. We anticipate
that our expenses will increase substantially in connection with our ongoing
activities, as we:

continue to conduct our ongoing clinical trials of adintrevimab, including advancement through late-stage global clinical trials, as well as initiate and complete additional clinical trials of future product candidates or current product candidates in new indications or patient populations;


                                      107
--------------------------------------------------------------------------------

continue to advance the preclinical development of our other product candidates and our preclinical and discovery programs;

seek regulatory approval for any product candidates that successfully complete clinical trials;

pursue marketing approvals or EUA and reimbursement for our product candidates;

acquire or in-license other product candidates, intellectual property and/or technologies;

develop, establish and validate our commercial-scale current good manufacturing practices, or cGMP, manufacturing process;

manufacture material under cGMP for clinical trials and potential EUA and commercial sales at our contracted manufacturing facilities;

maintain, expand, enforce, defend and protect our intellectual property portfolio;

comply with regulatory requirements established by the applicable regulatory authorities;

establish a sales, marketing and distribution infrastructure and scale up manufacturing capabilities to commercialize any product candidates for which we may obtain regulatory approval or EUA;


hire and retain additional personnel, including research, clinical, development,
manufacturing, quality control, quality assurance, regulatory and scientific
personnel;

add operational, financial, corporate development, management information systems and administrative personnel, including personnel to support our product development and planned future commercialization efforts; and

incur additional legal, accounting and other expenses in operating as a public company.



We do not anticipate generating revenue from product sales, including government
supply contracts, unless and until we successfully complete clinical development
and obtain marketing approvals or EUA for one or more of our product candidates.
We are currently establishing our commercial infrastructure to support the
anticipated marketing and distribution of our product candidates. Subject to
receiving marketing approval or EUA for any of our product candidates for the
prevention and/or treatment of COVID-19, we expect to enter into arrangements
with third parties for the sale, marketing and distribution of our product
candidates. Accordingly, if we obtain marketing approval or EUA for any of our
product candidates, we will incur significant additional commercialization
expenses related to product manufacturing, marketing, sales and distribution.

As a result, we will need substantial additional funding to support our
continuing operations and pursue our growth strategy. Until such time as we can
generate significant revenue from product sales, if ever, we expect to finance
our operations through a combination of equity offerings, government or
private-party grants, debt financings, collaborations with other companies and
strategic alliances. We may be unable to raise additional funds or enter into
such other agreements or arrangements when needed on favorable terms, or at all.
If we fail to raise capital or enter into such agreements as, and when, needed,
we may have to significantly delay, scale back or discontinue the development
and commercialization of one or more of our product candidates or delay our
pursuit of potential in-licenses or acquisitions.

Because of the numerous risks and uncertainties associated with pharmaceutical
product development, we are unable to accurately predict the timing or amount of
increased expenses or when, or if, we will be able to achieve or maintain
profitability. We may never obtain regulatory approval for any of our product
candidates. Even if we are able to generate product sales, we may not become
profitable. If we fail to become profitable or are unable to sustain
profitability on a continuing basis, then we may be unable to continue our
operations at planned levels and be forced to reduce or terminate our
operations.

Based on our current operating plan, we believe that our existing cash, cash
equivalents and marketable securities of $591.4 million as of December 31, 2021,
will be sufficient to fund our operating expenses and capital expenditure
requirements into the second half of 2024. We have based this estimate on
assumptions that may prove to be wrong, and we could exhaust our available
capital resources sooner than we expect. See "-Liquidity and Capital Resources."

Impact of COVID-19 on Our Operations



In March 2020, the World Health Organization declared the outbreak of COVID-19 a
global pandemic. The evolving and constantly changing impact of the pandemic
will directly affect the potential commercial prospects of adintrevimab for the
prevention and treatment of COVID-19. The severity of the COVID-19 pandemic and
the continued emergence of variants of

                                      108
--------------------------------------------------------------------------------


concern (such as the widespread Omicron and Delta variants), the availability,
administration and acceptance of vaccines, monoclonal antibodies, antiviral
agents and other therapeutic modalities, the introduction of local, national
and/or employer vaccine mandates, and the potential development of "herd
immunity" by the global population will affect the design and enrollment of our
clinical trials, the potential regulatory authorization or approval of our
product candidates and the commercialization of our product candidates, if
approved.

In addition, our business and operations may be more broadly adversely affected
by the COVID-19 pandemic. The COVID-19 outbreak and government measures taken in
response have had a significant impact, both direct and indirect, on businesses
and commerce, as worker shortages have occurred, supply chains have been
disrupted, facilities and production have been suspended and demand for certain
goods and services, such as medical services and supplies, has spiked, while
demand for other goods and services has fallen. The global COVID-19 pandemic
continues to evolve rapidly, and we will continue to monitor it closely. The
ultimate extent of the impact of the COVID-19 pandemic on our business,
financial condition, operations and product development timelines and plans
remains highly uncertain and will depend on future developments, including the
duration and spread of outbreaks and the continued emergence of variants, its
impact on our clinical trial design and enrollment, trial sites, contract
research organizations, or CROs, contract development and manufacturing
organizations, or CDMOs, and other third parties with which we do business, as
well as its impact on regulatory authorities and our key scientific and
management personnel. To date, we have experienced some delays and disruptions
in our development activities as a result of the COVID-19 pandemic. Some of our
CROs, CDMOs and other service providers also continue to be impacted. We will
continue to monitor developments as we address the disruptions, delays and
uncertainties relating to the COVID-19 pandemic. These developments and the
impact of the COVID-19 pandemic on the financial markets and the overall economy
are highly uncertain and cannot be predicted. If the financial markets and/or
the overall economy are impacted for an extended period, our results and
operations may be materially adversely affected and may affect our ability to
raise capital.

Components of Our Results of Operations

Revenue



To date, we have not generated any revenue from product sales, including
government supply contracts, or any other sources. If our development efforts
for our product candidates are successful and result in regulatory approval or
collaboration or license agreements with third parties, we may generate revenue
in the future from product sales or payments from collaboration or license
agreements that we may enter into with third parties, or any combination
thereof.

Research and Development Expenses

The nature of our business and primary focus of our activities generate a significant amount of research and development costs. Research and development expenses represent costs incurred by us for:

the non-clinical and preclinical development of our product candidates, including our discovery efforts;

the procurement of our product candidates from third-party manufacturers; and

the global clinical development of our product candidates

Such costs consist of:

personnel-related expenses, including salaries, bonuses, benefits and other compensation-related costs, including stock-based compensation expense, for employees engaged in research and development functions;

expenses incurred under agreements with third parties, such as consultants, contractors and CROs, that conduct the non-clinical and preclinical studies and clinical trials of our product candidates and research programs;

costs of procuring manufactured product candidates for use in non-clinical studies, preclinical studies and clinical trials from third-party CDMOs;

costs of outside consultants and advisors, including their fees and stock-based compensation;

payments made under third-party licensing agreements; and

other expenses incurred as a result of research and development activities.


                                      109
--------------------------------------------------------------------------------


We expense research and development costs as incurred. Non-refundable advance
payments that we make for goods or services to be received in the future for use
in research and development activities are recorded as prepaid expenses. The
prepaid amounts are expensed as the related goods are delivered or the services
are performed, or when it is no longer expected that the goods will be delivered
or the services rendered.

Our primary focus since inception has been the development of adintrevimab. Our
research and development costs consist primarily of external costs, such as fees
paid to CDMOs, CROs and consultants in connection with our non-clinical studies,
preclinical studies and clinical trials. To date, external research and
development costs for any individual product candidate have been tracked
commencing upon product candidate nomination. We do not allocate
employee-related costs, costs associated with our discovery efforts and other
internal or indirect costs to specific research and development programs or
product candidates because these resources are used and these costs are deployed
across multiple programs under development and, as such, are not separately
classified.

Research and development activities are central to our business model. Product
candidates in later stages of clinical development generally have higher and
more variable development costs than those in earlier stages of clinical
development, primarily due to the increased size and duration of later-stage
clinical trials. We expect that our research and development expenses will
increase substantially in the near term as we advance adintrevimab through
clinical development on a global basis, pursue regulatory approval of
adintrevimab, continue to discover and develop additional product candidates and
incur expenses associated with hiring additional personnel to support our
research and development efforts, including the associated manufacturing
activities.

At this time, we cannot reasonably estimate or know the nature, timing and
estimated costs of the efforts that will be necessary to complete the
development of any of our product candidates. We are also unable to predict
when, if ever, material net cash inflows will commence from sales or licensing
of our product candidates. This is due to the numerous risks and uncertainties
associated with drug development, including the uncertainty of:

the timing and progress of preclinical and clinical development activities;

the number and scope of preclinical and clinical programs we decide to pursue;


filing acceptable investigational new drug applications with the U.S. Food and
Drug Administration or comparable foreign applications that allow commencement
of our planned clinical trials or future clinical trials for our product
candidates;

sufficiency of our financial and other resources to complete the necessary preclinical studies and clinical trials, manufacture the product candidates and complete associated regulatory activities;


our ability to establish and maintain agreements with third-party manufacturers
for clinical supply for our clinical trials and successfully develop, obtain
regulatory approval or EUA for our product candidates;

successful enrollment and timely completion of clinical trials, including our ability to generate positive data from any such clinical trials;

the costs associated with the development of any additional development programs and product candidates we identify in-house or acquire through collaborations;

the prevalence, nature and severity of adverse events experienced with adintrevimab or any other product candidates;

the terms and timing of any collaboration, license or other arrangement, including the terms and timing of any milestone payments thereunder;


our ability to obtain and maintain patent, trademark and trade secret protection
and regulatory exclusivity for our product candidates, if and when approved, and
otherwise protecting our rights in our intellectual property portfolio;

receipt of timely marketing approvals from applicable regulatory authorities;


our ability to maintain compliance with regulatory requirements, including good
clinical practices, current good laboratory practices and cGMPs, and to comply
effectively with other rules, regulations and procedures applicable to the
development and sale of pharmaceutical products;

potential significant and changing government regulation, regulatory guidance and requirements and evolving treatment guidelines; and


                                      110
--------------------------------------------------------------------------------

the impact of any business interruptions to our operations or those of third parties with which we work, particularly in light of the current COVID-19 pandemic.



A change in the outcome of any of these variables with respect to the
development of any of our product candidates could significantly change the
costs and timing associated with the development of that product candidate. We
may elect to discontinue, delay or modify clinical trials of some product
candidates or focus on others. We may never succeed in obtaining regulatory
approval or EUA for any of our product candidates. In addition, in the absence
of a public health emergency, we will not be able to receive an EUA. The
national public health emergency declaration was most recently renewed in
January 2022 and may or may not be renewed again.

Acquired In-Process Research and Development Expenses



Acquired in-process research and development, or IPR&D, expenses consist
primarily of the upfront costs we incurred in July 2020, as well as any costs of
contingent milestone payments we incurred in subsequent periods, to acquire
rights to Adimab's antibodies relating to COVID-19 and SARS and related
intellectual property and a license to certain of Adimab's platform patents and
technology, or the IPR&D assets, for use in the research and development of our
product candidates. We expensed the cost of the IPR&D assets because they had no
alternative future use as of the acquisition date. We will recognize additional
acquired IPR&D expenses in the future if and when we become obligated to make
contingent milestone payments to Adimab under the terms of the agreement by
which we acquired the IPR&D assets.

Selling, General and Administrative Expenses



Selling, general and administrative expenses consist primarily of salaries,
bonuses, benefits, third-party fees and other related costs, including
stock-based compensation, for our personnel and external contractors involved in
our executive, finance, legal, business development and other administrative
functions as well as our commercial function. Selling, general and
administrative expenses also include costs incurred for outside services
associated with such functions, including legal fees relating to patent and
corporate matters; professional fees for accounting, auditing, tax and
administrative consulting services; insurance costs; market research costs; and
other selling, general and administrative expenses. These costs relate to the
operation of the business, unrelated to the research and development function,
or any individual program.

We anticipate that our selling, general and administrative expenses will
increase substantially in the future as our business expands and we increase our
headcount to support the expected growth in our research and development
activities and the potential commercialization of our product candidates. In
particular, we expect to incur additional commercialization expenses prior to
any regulatory approval or EUA of our product candidates as we continue to
expand our commercial function to support potential future product launches. We
also anticipate that we will incur increased expenses associated with operating
as a public company, including increased costs of accounting, audit, legal,
regulatory and tax-related services, director and officer insurance premiums,
and investor and public relations costs. We also expect to incur additional
intellectual property-related expenses as we file additional patent applications
to protect innovations arising from our research and development activities.

Through December 31, 2021, we have operated as a virtual company and maintain a
corporate headquarters for general and administrative purposes only. Therefore,
we do not incur material operating expenses for the rent, maintenance and
insurance of facilities or for depreciation of fixed assets.

Other Income (Expense), Net



Other income (expense), net consists of interest income earned from our cash,
cash equivalents and marketable securities and the net amortization or accretion
of premiums and discounts related to our marketable securities. We expect our
interest income to vary each reporting period depending on our average bank
deposits, money market funds and investment balances during the period and
market interest rates.

Income Taxes



Since our inception, we have not recorded any income tax expense or realized
benefits for the net losses we have incurred or for the research and development
tax credits generated in each period as we believe, based upon the weight of
available evidence, that it is more likely than not that all of our net
operating loss, or NOL, carryforwards and tax credit carryforwards will not be
realized.

Acquired In-Process Research and Development Expenses



Acquired IPR&D expenses of $7.5 million for the year ended December 31, 2021
consisted of the costs we incurred in the period under the Adimab Assignment
Agreement for a $1.0 million milestone payment that became due to Adimab in
February 2021 upon the dosing of the first patient in a Phase 1 clinical trial
evaluating adintrevimab, a $2.5 million milestone payment that became due to
Adimab in April 2021 upon the dosing of the first patient in the first Phase 2
clinical trial evaluating adintrevimab for the prevention of COVID-19, and a
$4.0 million milestone payment that became due to Adimab in August 2021 upon
dosing of the first patient in a Phase 3 clinical trial evaluating adintrevimab
for the prevention of COVID-19. The second and third milestones were achieved in
connection with our combined Phase 2/3 EVADE global clinical trial of
adintrevimab for the prevention of COVID-19. We recognized the expense related
to the first, second and third milestone payments in February, April and August
2021, respectively, when we deemed it probable that each specified milestone
would be achieved. The amounts of these contingent payments were recognized as
an IPR&D expense based on the nature, assessed as of each milestone achievement
date, of the assets originally acquired from Adimab.

Acquired IPR&D expenses of $40.1 million for the year ended December 31, 2020
consisted primarily of the $39.9 million of costs we incurred in July 2020 to
acquire rights to Adimab's antibodies relating to COVID-19 and SARS and related
intellectual property and a license to certain of Adimab's platform patents and
technology for use in the research and development of our product candidates.

million, consisting primarily of $1.7 million of interest earned on our invested
cash balances, partially offset by $1.4 million of net amortization of premiums
related to our marketable securities.

Other income (expense), net for the year ended December 31, 2020 was less than $0.1 million, consisting of interest earned on our invested cash balances.

Liquidity and Capital Resources

Sources of Liquidity



Since our inception in June 2020, we have not generated any revenue from any
sources, including from product sales, and have incurred significant operating
losses and negative cash flows from operations. We expect to incur substantial
expenses and operating losses for the foreseeable future as we advance the
clinical development of our product candidates. To date, we have financed our
operations with net proceeds of $464.7 million from sales of our preferred
stock, and most recently, with net proceeds from our IPO in August 2021, in
which we issued and sold 20,930,000 shares of our common stock, including
2,730,000 shares of common stock pursuant to the full exercise of the
underwriters' option to purchase additional shares. We received aggregate net
proceeds from our IPO of $327.5 million, after deducting underwriting discounts
and commissions and offering expenses payable by us.

As of December 31, 2021, we had cash, cash equivalents and marketable securities of $591.4 million.



Cash Flows

The following table summarizes our sources and uses of cash for each of the
periods presented:

                                                                              Period from

Operating Activities

During the year ended December 31, 2021, operating activities used $184.7
million of cash, primarily due to our net loss of $226.8 million, partially
offset by non-cash charges of $19.3 million and net cash provided by changes in
our operating assets and liabilities of $22.8 million. Net cash provided by
changes in our operating assets and liabilities consisted of a $51.3 million
increase in accrued expenses, partially offset by a $22.9 million increase in
prepaid expenses and other current assets, a $3.3 million increase in other
non-current assets and a $2.4 million decrease in accounts payable. The increase
in accrued expenses was primarily due to amounts owed to vendors in connection
with our research and development activities, including increased external costs
associated with clinical trials and manufacturing. The increase in prepaid
expenses and other current assets and other non-current assets was primarily due
to prepayments for external research and development activities and prepayments
for insurance premiums. The decrease in accounts payable was primarily due to
the timing of invoices received and payments made.

During the period from June 3, 2020 (inception) to December 31, 2020, operating
activities used $14.6 million of cash, primarily due to our net loss of $65.3
million, partially offset by non-cash charges of $40.1 million and net cash
provided by changes in our operating assets and liabilities of $10.7 million.
Net cash provided by changes in our operating assets and liabilities consisted
of an $8.2 million increase in accounts payable and a $4.9 million increase in
accrued expenses, both partially offset by a $2.4 million increase in prepaid
expenses and other current assets. The increases in accounts payable and accrued
expenses were primarily due to amounts owed to vendors in connection with our
research and development activities, including increased external costs
associated with clinical trials and manufacturing, as well as increases in
accrued employee bonuses. The increase in prepaid expenses and other current
assets was primarily due to prepayments for external research and development
activities.

Investing Activities

During the year ended December 31, 2021, net cash used in investing activities
was $50.7 million, primarily related to purchases of marketable securities of
$188.6 million, offset by maturities of marketable securities of $138.0 million.

We had no cash used in or provided by investing activities for the period from June 3, 2020 (inception) to December 31, 2020.

Financing Activities



During the year ended December 31, 2021, net cash provided by financing
activities was $662.7 million, primarily related to net proceeds of $335.2
million from the issuance of our Series C preferred stock in April 2021 and net
proceeds of $330.9 million from the issuance of our common stock in connection
with our IPO in August 2021, offset by $3.4 million of payments of initial
public offering costs.

During the period from June 3, 2020 (inception) to December 31, 2020, net cash
provided by financing activities was $129.6 million, primarily related to net
proceeds of $49.7 million from the issuance of our Series A preferred stock in
July 2020 and net proceeds of $79.8 million from the issuance of our Series B
preferred stock in October and November 2020.

--------------------------------------------------------------------------------

Funding Requirements



We expect our expenses to increase substantially in connection with our ongoing
activities, particularly as we advance the non-clinical and preclinical studies
and the current and future clinical trials of our product candidates. Our
funding requirements and timing and amount of our operating expenditures will
depend on many factors, including:

the rate of progress in the development of adintrevimab and our other product candidates;

the scope, progress, results and costs of non-clinical studies, preclinical development, laboratory testing and clinical trials for adintrevimab and future product candidates and associated development programs;

the extent to which we develop, in-license or acquire other product candidates and technologies in our pipeline;


the scope, progress, results and costs as well as timing of process development
and manufacturing scale-up and validation activities associated with
adintrevimab and our future product candidates and other programs as we advance
them through preclinical and clinical development;

the number and development requirements of product candidates that we may pursue;

the costs, timing and outcome of regulatory review of our product candidates;

our headcount growth and associated costs as we expand our research and development capabilities and establish a commercial infrastructure;

the timing and costs of securing sufficient capacity for commercial supply of our product candidates, or the raw material components thereof;

the costs and timing of future commercialization activities, including product manufacturing, marketing, sales and distribution, for any of our product candidates for which we receive marketing approval or EUA;


the costs necessary to obtain regulatory approvals, if any, for products in the
United States and other jurisdictions, and the costs of post-marketing studies
that could be required by regulatory authorities in jurisdictions where approval
is obtained;


the costs and timing of preparing, filing and prosecuting patent applications,
maintaining and enforcing our intellectual property rights and defending any
intellectual property-related claims;

the continuation of our existing licensing and collaboration arrangements and entry into new collaborations and licensing arrangements, if at all;

the need and ability to hire additional research, clinical, development, scientific and manufacturing personnel;

the costs we incur in maintaining business operations;

the need to implement additional internal systems and infrastructure;

the effect of competing technological, product and market developments;

the revenue, if any, received from commercial sales of our product candidates for which we receive marketing approval;

the costs of operating as a public company; and


the progression of the COVID-19 pandemic and emergence of potential outbreaks of
other coronaviruses, including the impact of any business interruptions to our
operations or to those of our contract manufacturers, suppliers or other vendors
resulting from the COVID-19 pandemic or other similar public health crises.

We believe that our cash, cash equivalents and marketable securities, will
enable us to fund our operating expenses and capital expenditure requirements
into the second half of 2024. We have based this estimate on assumptions that
may prove to be wrong, and we could exhaust our available capital resources
sooner than we expect.

Until such time, if ever, as we can generate substantial product revenue, we
expect to finance our operations through a combination of equity offerings,
government or private-party grants, debt financings, collaborations, strategic
alliances and licensing arrangements. To the extent that we raise additional
capital through the sale of equity or convertible debt securities, your
ownership interest will be diluted, and the terms of such securities may include
liquidation or other preferences and anti-dilution protections that adversely
affect your rights as a common stockholder. Additional debt financing and
preferred equity financing, if available, may involve agreements that include
covenants limiting or restricting our ability to take specific actions,

                                      116
--------------------------------------------------------------------------------


such as incurring debt, making acquisitions or capital expenditures or declaring
dividends, which could adversely constrain our ability to conduct our business,
and may require the issuance of warrants, which could potentially dilute your
ownership interest. If we raise additional funds through collaborations,
strategic alliances or licensing arrangements with third parties, we may have to
relinquish valuable rights to our technologies, future revenue streams, research
programs, or product candidates or grant licenses on terms that may not be
favorable to us. If we are unable to raise additional funds through equity or
debt financings or through other sources, when needed, we may be required to
delay, limit, reduce or terminate our product development programs or any future
commercialization efforts or grant rights to develop and market product
candidates to third parties that we would otherwise prefer to develop and market
ourselves.

Amounts represent minimum purchase commitments under an arrangement with our
CDMO for commercial supply. The table reflects obligations that are
non-cancelable as of December 31, 2021, based on the expected due dates for such
purchases.

Amounts represent minimum payments due under our operating lease agreement for
office space in Waltham, Massachusetts, which expires in 2026 with an option to
terminate in 2023.

In December 2020, we entered into a Commercial Manufacturing Services Agreement
with WuXi, which was amended and restated in August 2021 (as amended and
restated, the Commercial Manufacturing Agreement). The Commercial Manufacturing
Agreement outlines the terms and conditions under which WuXi will manufacture
adintrevimab drug substance and drug product for commercial use. Our
requirements for manufacture of adintrevimab for the year ending December 31,
2022, the payments for which will extend into 2023, are governed by a binding,
forecasted schedule and are presented in the preceding table.

In September 2021, we entered into a five-year lease agreement for approximately
9,600 square feet of office space in Waltham, Massachusetts. The monthly rental
payments under the lease agreement, which include base rent charges of
approximately $0.4 million per year, are subject to periodic rent increases
through September 2026.

Under a separate cell line license agreement with WuXi, as of December 31, 2020,
we were obligated to pay a license fee of $0.2 million to WuXi, which was an
accrued expense as of December 31, 2020 and paid during the year ended December
31, 2021. Under the agreement, we are obligated to pay royalties in the range of
0.3% to 0.5% to WuXi based on our net sales of any products covered by the
license. However, if we use WuXi to manufacture all of our commercial supplies,
no royalties would be owed by us to WuXi for net sales of licensed products. We
have an option to buy out our royalty obligations by making a one-time payment
of $15.0 million to WuXi. These royalty payments are not included in the
preceding table as the amount and timing of such payments are not known.

In July 2020, we entered into an assignment and license agreement with Adimab,
or the Adimab Assignment Agreement, with respect to discovery and optimization
of coronavirus-specific antibodies, including COVID-19 and SARS. Under the
Adimab Assignment Agreement, we are obligated to pay Adimab up to $16.5 million
upon the achievement of specified development and regulatory milestones for the
first product licensed under the agreement that achieves specified development
and regulatory events and up to $8.1 million upon the achievement of specified
development and regulatory milestones for the second product licensed under the
agreement that achieves such development and regulatory events. In February
2021, we achieved the first specified milestone under the agreement upon dosing
of the first patient in a Phase 1 global clinical trial evaluating adintrevimab,
which obligated us to make a $1.0 million payment to Adimab. We made the payment
in March 2021. In April 2021, we achieved the second specified milestone under
the agreement upon dosing of the first patient in a Phase 2 global clinical
trial evaluating adintrevimab for the prevention of COVID-19, which obligated us
to make a $2.5 million payment to Adimab. We made the payment in June 2021. In
August 2021, we achieved the third specified milestone under the agreement upon
dosing of the first patient in a Phase 3 global clinical trial evaluating
adintrevimab for the prevention of COVID-19, which obligated us to make a $4.0
million milestone payment to Adimab. The next potential milestone under the

                                      117
--------------------------------------------------------------------------------


Adimab Assignment Agreement is a $4.0 million milestone related to the
acceptance of the filing of the first New Drug Application for a product
licensed under the agreement by the FDA. In addition, we are obligated to pay
Adimab royalties of a mid single-digit percentage based on our net sales of any
products covered by the rights assigned. Further, we are obligated to pay Adimab
royalties of a specified percentage in the range of 45% to 55% of any compulsory
sublicense consideration received by us in lieu of certain royalty payments.
These milestone and royalty payments are not included in the preceding table as
the amount and timing of such payments are not known. For additional
information, see to Note 7 to our annual consolidated financial statements
appearing at the end of this Annual Report on Form 10-K.

In May 2021, we entered into a collaboration agreement with Adimab, or the
Adimab Collaboration Agreement, for the discovery and optimization of
proprietary antibodies as potential therapeutic product candidates. Under the
Adimab Collaboration Agreement, we and Adimab will collaborate on research
programs for a specified number of targets selected by us within a specified
time period. Under the agreement, we are obligated to pay Adimab a quarterly fee
of $1.3 million, in exchange for Adimab and its affiliates agreeing not to
assist or direct certain third parties to discover or optimize antibodies that
are intended to bind to coronaviruses or influenza viruses, which obligation may
be cancelled at our option at any time. For each agreed upon research program
that is commenced, we are obligated to pay Adimab quarterly for its services
performed during a given research program at a specified full-time equivalent
rate; a discovery delivery fee of $0.2 million; and an optimization completion
fee of $0.2 million. For each option exercised by us to commercialize a specific
research program, we are obligated to pay Adimab an exercise fee of $1.0
million. Under the Adimab Collaboration Agreement, we are obligated to pay
Adimab up to $18.0 million upon the achievement of specified development and
regulatory milestones for each product under the agreement that achieves such
milestones. We are also obligated to pay Adimab royalties of a mid single-digit
percentage based on annual aggregate worldwide net sales of products, subject to
reductions for third-party licenses. In addition, we are obligated to pay Adimab
for Adimab's performance of certain validation work with respect to certain
antigens acquired from a third party. In consideration for this work, we are
obligated to pay Adimab royalties of a low single-digit percentage based on
annual aggregate worldwide net sales of products that contain such antigens for
the same royalty term as antibody-based products, but we are not obligated to
make any milestone payments for such antigen products. These milestone and
royalty payments are not included in the preceding table as the amount and
timing of such payments are not known. For additional information, see to Note 7
to our annual consolidated financial statements appearing at the end of this
Annual Report on Form 10-K.

In August 2021, we entered into a research collaboration and license agreement,
or the Research Agreement, with The Scripps Research Institute, or TSRI. Under
the terms of the Research Agreement, TSRI will perform research activities to
identify vaccine candidates for the prevention, diagnosis or treatment of
influenza or beta coronaviruses, or the Research Program. The Company is
obligated to provide the research funding necessary to carry out each activity
initiated under the Research Program pursuant to a budget to be agreed upon by
the parties. In August 2021, the Company paid TSRI $1.5 million in funding,
which was credited against research funding payable by the Company under the
Research Agreement. Additionally, the Company is obligated to make specified
payments to TSRI to the extent that TSRI complies with certain exclusivity
covenants. To the extent any product licensed under the Research Agreement is
commercialized, the Company is obligated to pay TSRI royalties of a low
single-digit percentage on a licensed product-by-licensed product and
country-by-country basis based on a percentage of net sales, subject to
reduction and floor. Royalties are payable for each product on a
country-by-country basis through the later of (i) the expiration of the last
valid claim of any patent covering such product in such country or (ii) 12 years
from the first commercial sale of such product. The Research Agreement will
expire when no further royalties are due to TSRI. For additional information,
see to Note 7 to our annual consolidated financial statements appearing at the
end of this Annual Report on Form 10-K.

We enter into other contracts in the normal course of business with CROs,
contract manufacturing organizations and other third parties for preclinical
research studies and testing, clinical trials, manufacturing and other services.
These contracts do not contain any minimum purchase commitments and provide for
termination by us upon prior written notice. Payments due upon cancellation
consist only of payments for services provided and expenses incurred up to the
date of cancellation, including non-cancelable obligations of our service
providers and, in some cases, wind-down costs. The exact amounts of such
obligations are dependent on the timing of termination and the terms of the
associated agreement. Accordingly, these payments are not included in the
preceding table as the amount and timing of such payments are not known.

Critical Accounting Policies and Significant Judgments and Estimates



Our management's discussion and analysis of our financial condition and results
of operations is based on our consolidated financial statements, which have been
prepared in accordance with generally accepted accounting principles in the
United States, or GAAP. The preparation of consolidated financial statements
requires us to make estimates and assumptions that affect the reported amounts
of assets, and liabilities and the disclosure of contingent assets and
liabilities at

                                      118
--------------------------------------------------------------------------------


the date of the consolidated financial statements, as well as the reported
expenses incurred during the reporting periods. Our estimates are based on our
historical experience, known trends and events, and various other factors that
we believe are reasonable under the circumstances, the results of which form the
basis for making judgments about the carrying value of assets and liabilities
and recorded amounts of expenses that are not readily apparent from other
sources. We evaluate our estimates and assumptions on an ongoing basis. Our
actual results may differ from these estimates under different assumptions or
conditions.

While our significant accounting policies are described in more detail in Note 2
to our consolidated financial statements appearing at the end of this Annual
Report, we believe the following accounting policies used in the preparation of
our consolidated financial statements require the most significant judgments and
estimates.

Accrued Research and Development Expenses



As part of the process of preparing our consolidated financial statements, we
are required to estimate our accrued research and development expenses. This
process involves estimating the level of service performed and the associated
costs incurred for the services when we have not yet been invoiced or otherwise
notified of the actual costs. The majority of our service providers invoice us
in arrears for services performed, on a pre-determined schedule or when
contractual milestones are met; however, some require advance payments. We make
estimates of our accrued expenses as of each balance sheet date in the
consolidated financial statements based on facts and circumstances known to us
at that time. At each end period, we corroborate the accuracy of these estimates
with the service providers and make adjustments, if necessary. Examples of
estimated accrued research and development expenses include those related to
fees paid to:

CROs in connection with performing non-clinical studies, preclinical studies and clinical trials;

CDMOs related to the production of our product candidates for non-clinical studies, preclinical studies and clinical trials; and

other providers and vendors in connection with research and development activities.



We record the expense and accrual related to contract research and manufacturing
based on our estimates of the services received and efforts expended considering
a number of factors, including our knowledge of the progress towards completion
of the research, development and manufacturing activities; invoicing to date
under the contracts; communication from the CROs, CDMOs and other companies of
any actual costs incurred during the period that have not yet been invoiced; and
the costs included in the contracts and purchase orders. The financial terms of
these agreements are subject to negotiation, vary from contract to contract and
may result in uneven payment flows. For CRO expense and accruals, there is
estimation uncertainty related to the timing of submission of investigator fees
for the period. For CDMO expense and accruals, there is estimation uncertainty
related to the percentage of completion of in process batch manufacturing at
period end. To date, we have not had significant changes to our estimates. 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. In accruing service
fees, we estimate the time period over which services will be performed and the
level of effort to be expended in each period. If the actual timing of the
performance of services or the level of effort varies from the estimate, we
adjust the accrual or the amount of prepaid expense accordingly. 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
relative to the actual status and timing of services performed may vary and may
result in reporting amounts that are too high or too low in any particular
period. To date, there have not been any material adjustments to our prior
estimates of accrued research and development expenses.

Asset Acquisitions and Acquired In-Process Research and Development Expenses



We measure and recognize asset acquisitions that are not deemed to be business
combinations based on the cost to acquire the asset or group of assets, which
includes transaction costs. Goodwill is not recognized in asset acquisitions. In
an asset acquisition, the cost allocated to acquire IPR&D with no alternative
future use is recognized as expense on the acquisition date.

Contingent consideration in asset acquisitions payable in the form of cash is
recognized in the period the triggering event is determined to be probable of
occurrence and the related amount is reasonably estimable. Such amounts are
expensed or capitalized based on the nature of the associated asset at the date
the related contingency is resolved.

We concluded that the agreement under which we acquired rights to Adimab's
antibodies relating to COVID-19 and SARS and related intellectual property and a
license to certain of Adimab's platform patents and technology in June 2020
represented an asset acquisition of IPR&D assets with no alternative future use.
We further concluded that the arrangement did

                                      119
--------------------------------------------------------------------------------

not qualify as a business combination because substantially all of the fair value of the assets acquired was concentrated in a single asset.

Determination of Fair Value of Common Stock



Prior to the initial public offering, as there was no public market for our
common stock, the estimated fair value of our common stock underlying our
stock-based awards was determined by our board of directors as of each option
grant date with input from management, considering our most recently available
third-party valuations of common stock and our board of directors' assessment of
additional objective and subjective factors that it believed were relevant and
which may have changed from the date of the most recent valuation through the
date of the grant. These third-party valuations were prepared in accordance with
the guidance outlined in the American Institute of Certified Public Accountants'
Accounting and Valuation Guide, Valuation of Privately-Held Company Equity
Securities Issued as Compensation. Our common stock valuations were prepared
using either a current value method, or CVM, an option pricing method, or OPM,
or a hybrid method. To estimate our enterprise value, the CVM used an asset
approach and the OPM and hybrid methods used a market approach. Under the CVM,
once the fair value of the enterprise is established based on the balance sheet,
the value is allocated to the various series of preferred and common stock based
on their respective liquidation preferences or conversion values, whichever is
greater. The OPM treats common stock and preferred stock as call options on the
total equity value of a company, with exercise prices based on the value
thresholds at which the allocation among the various holders of a company's
securities changes. Under this method, the common stock has value only if the
funds available for distribution to stockholders exceeded the value of the
preferred stock liquidation preferences at the time of the liquidity event, such
as a strategic sale or a merger. The hybrid method is a probability-weighted
expected return method, or PWERM, where the equity value in one or more of the
scenarios is calculated using an OPM. The PWERM is a scenario-based methodology
that estimates the fair value of common stock based upon an analysis of future
values for the company, assuming various outcomes. The common stock value is
based on the probability-weighted present value of expected future investment
returns considering each of the possible outcomes available as well as the
rights of each class of stock. The future value of the common stock under each
outcome is discounted back to the valuation date at an appropriate risk-adjusted
discount rate and probability weighted to arrive at an indication of value for
the common stock. A discount for lack of marketability of the common stock is
then applied to arrive at an indication of value for the common stock.

Prior to the initial public offering, these third-party valuations were
performed at various dates. In addition to considering the results of these
third-party valuations, our board of directors considered various objective and
subjective factors to determine the fair value of common stock as of each grant
date, including:

the prices at which we sold our preferred stock and the superior rights and preferences of our preferred stock relative to those of our common stock at the time of each grant;

the progress of our research and development programs, including the status of preclinical studies and clinical trials for our product candidates;

our stage of development and our business strategy;

external market conditions affecting the biotechnology industry and trends within the biotechnology industry;

the competitive landscape for similar products for the treatment and prevention of COVID-19;

our financial position, including cash on hand, and our historical and forecasted performance and operating results;

the lack of an active public market for our common stock and our preferred stock;

the likelihood of achieving a liquidity event, such as an initial public offering, or IPO, or a sale of our company, given prevailing market conditions; and

the analysis of IPOs and the market performance of similar companies in the biopharmaceutical industry.

The assumptions underlying these valuations represented management's best estimate, which involved inherent uncertainties and the application of management's judgment. As a result, if we had used significantly different assumptions or estimates, the fair value of our common stock and our stock-based compensation expense could be materially different.

Stock-Based Compensation



We grant stock-based awards to employees, directors and non-employees in the
form of stock options to purchase shares of our common stock. We measure stock
options with service-based vesting granted to employees, directors and
non-employees

                                      120
--------------------------------------------------------------------------------


based on the fair value on the date of grant using the Black-Scholes
option-pricing model. The Black-Scholes option-pricing model uses as inputs the
fair value of our common stock and assumptions we make for the volatility of our
common stock, the expected term of our stock options, the risk-free interest
rate for a period that approximates the expected term of our stock options, and
our expected dividend yield. After the initial public offering, the fair value
of our common stock is based on the quoted market price of our common stock. Due
to the proximity to the IPO, we continue to lack company-specific historical and
implied volatility information. Therefore, we estimate our expected stock
volatility based on the historical volatility of a publicly traded set of peer
companies and we expect to continue to do so until such time that we have
adequate historical data regarding the volatility of our own traded stock price.
We have issued awards with only service-based vesting conditions through
December 31, 2021. Compensation expense for awards granted to employees and
directors for their service on the board of directors is recognized on a
straight-line basis over the requisite service period of the respective award,
which is generally the vesting period of the award. Compensation expense for
awards granted to non-employees is recognized in the same period and manner as
if we had paid cash for the goods or services provided, which is generally the
vesting period of the award. We account for forfeitures of stock-based awards as
they occur.

In future periods, we expect stock-based compensation expense to increase due to
our existing unrecognized stock-based compensation expense and to additional
stock-based awards we expect to grant to continue to attract new hires and
retain our existing employees.

Recently Issued Accounting Pronouncements



A description of recently issued accounting pronouncements that may potentially
impact our financial position, results of operations and cash flows is disclosed
in Note 2 to our consolidated financial statements appearing at the end of this
Annual Report on Form 10-K.

Emerging Growth Company Status



The Jumpstart Our Business Startups Act of 2012 permits an "emerging growth
company" such as us to take advantage of an extended transition period to comply
with new or revised accounting standards applicable to public companies until
those standards would otherwise apply to private companies. We have elected not
to "opt out" of such extended transition period, which means that when a
standard is issued or revised and it has different application dates for public
or private companies, we will adopt the new or revised standard at the time
private companies adopt the new or revised standard and will do so until such
time that we either (i) irrevocably elect to "opt out" of such extended
transition period or (ii) no longer qualify as an emerging growth company. We
may choose to early adopt any new or revised accounting standards whenever such
early adoption is permitted for private companies.
