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 ("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 capabilities 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 potentially differentiate adintrevimab, including
breadth, potency, durability of protection, convenient intramuscular
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
August 8, 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 safety and efficacy data were evaluated.

In the primary analysis population, patients infected with or exposed to a
non-Omicron variant (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 reverse
transcription-polymerase chain reaction ("RT-PCR") confirmed symptomatic
COVID-19. In an exploratory analysis of patients exposed to the Omicron variant
(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 74% compared to
placebo. A preliminary analysis of available safety data in each trial revealed
a safety profile similar to that of placebo for adintrevimab.

The Omicron BA.4 and BA.5 sublineages, which have shown reduced in vitro
susceptibility to monoclonal antibodies, have recently emerged as the current
predominant variants of SARS-CoV-2 in the United States. Adintrevimab, which has
demonstrated broadly neutralizing activity in vitro against SARS-CoV-2 variants
of concern including Alpha, Beta, Delta, Delta Plus, Gamma and Omicron BA.1, has
markedly reduced neutralization activity in vitro against the Omicron BA.2,
BA.4, and BA.5 sublineages. Based on feedback from the FDA regarding
adintrevimab's lack of neutralizing activity against the BA.2 variant, we paused
the submission of an Emergency Use Authorization ("EUA") request. We intend to
continue engaging with the FDA and monitor the evolution of SARS-CoV-2 and the
in vitro activity of adintrevimab against predominant variants in the United
States to determine the optimal timing for the planned EUA request. In addition,
we continue engaging with other health authorities outside of the United States
on potential authorization pathways for adintrevimab.

                                       23
--------------------------------------------------------------------------------


We are committed to advancing adintrevimab as a potential future therapeutic
option in anticipation of the emergence of new variants. We are on-track to have
more than 700,000 doses of adintrevimab secured in 2022, in preparation of its
potential utility as a prophylaxis and treatment option for COVID-19 in the
future.

We are also evaluating additional broadly neutralizing antibodies targeting the
receptor binding domain, as well as other subdomains within the spike protein
for COVID-19. We are advancing proprietary antibodies targeting distinct sites
with activity against all SARS-CoV-2 variants of concern ("VOCs") to date,
including the Omicron variant and its sublineages, and plan to take a
combination of these antibodies into clinical trials in the first quarter of
2023 for the prevention and treatment of COVID-19. In addition, we plan to
leverage our robust antibody discovery and development capabilities and our
partnerships that together 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.
We continue to evaluate product candidates for infectious diseases with high
unmet medical need through in-licensing opportunities that may leverage our
team's expertise and capabilities.

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 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 (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 ("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 us, we 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, we engage other third parties to perform ongoing research and
development and other services on our 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 partnerships, external consultants and
contract research organizations ("CROs") to conduct our discovery, non-clinical,
preclinical and clinical activities. Additionally, we are currently dependent on
WuXi Biologics (Hong Kong) Limited ("WuXi"), a contract development and
manufacturing organization ("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 ("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 or government
supply contracts. 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 a net loss
of $151.7 million for the six months ended June 30, 2022. As of June 30, 2022,
we had an accumulated deficit of $443.8 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. Our expenses could increase substantially
in connection with our ongoing activities, as we:

                                       24
--------------------------------------------------------------------------------

continue to conduct our ongoing clinical trials of adintrevimab, as well as initiate and complete additional clinical trials of future product candidates or current product candidates in new indications or patient populations;

continue to advance the preclinical development of our other product candidates and our preclinical and discovery programs, including any modification of adintrevimab and development and screening of additional antibodies;

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 discovery technologies;

validate our commercial-scale current good manufacturing practices ("cGMP") manufacturing process;

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

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 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 and emergence of adintrevimab susceptible SARS-CoV-2 VOCs,
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 and cash
equivalents of $474.9 million as of June 30, 2022, will be sufficient to fund
our operating expenses and capital expenditure requirements into the second
quarter 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 and
other product candidates for the prevention and treatment of COVID-19. The
severity of the COVID-19 pandemic and the continued emergence of VOCs (such as
the widespread Omicron variant and its sublineages and the Delta variant), the
availability, administration and acceptance of vaccines, monoclonal antibodies,
antiviral agents and other therapeutic modalities, vaccine mandates by employers
and/or local or

                                       25
--------------------------------------------------------------------------------


national governments, 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, CROs, 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 generates 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 collaborators,
consultants, contractors and CROs, that conduct the discovery, 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;

laboratory-related expenses, which include laboratory supplies, rent expense and other operating costs;

payments made under third-party licensing agreements; and

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



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

                                       26
--------------------------------------------------------------------------------


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. Our research and development expenses could increase
substantially in the near term as we advance adintrevimab through clinical
development on a global basis, if required, pursue regulatory approval of
adintrevimab, advance additional antibody candidates into clinical trials,
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 FDA 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

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 declaration by the U.S. Department of Health and Human Services of a
federal public health emergency (a "Public Health Emergency"), we will not be
able to receive an EUA. The declaration of a Public Health Emergency has
recently been extended to mid-October 2022 and may or may not be renewed again.

Acquired In-Process Research and Development Expenses

Acquired in-process research and development ("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


                                       27
--------------------------------------------------------------------------------


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 it is deemed probable that we will 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.

Our selling, general and administrative expenses could increase 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 could 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
continue to 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.

In June 2022, we entered into a two year noncancelable agreement for laboratory
and office space in Newton, MA for research and development purposes. Through
June 30, 2022, we have operated as a virtual company and maintained a corporate
headquarters for general and administrative purposes only. Therefore, we did 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 ("NOL") carryforwards and tax credit carryforwards will not be
realized.

expenses:
Personnel-related costs                                9,197            5,340          3,857

1,696 3,023 Total research and development expenses $ 37,129 $ 35,067 $ 2,062




Research and development expenses were $37.1 million for the three months ended
June 30, 2022, compared to $35.1 million for the three months ended June 30,
2021. The $2.0 million increase in research and development expenses was
primarily due to the following:


The decrease in direct costs related to our adintrevimab program of $4.8 million
was primarily due to a decrease in our contract manufacturing and contract
research expenses of $5.1 million related to the production of materials for use
in our clinical trials and nonclinical studies for the adintrevimab program, as
well as supply for use under a potential EUA for adintrevimab, procured from
WuXi, our sole-source supplier of drug substance and drug product, and a
decrease in other external research and development costs of $0.3 million. This
was offset by an increase in our clinical trial expenses of $0.6 million related
to ongoing monitoring activities for our clinical trials for the adintrevimab
program, partially offset by lower costs due to a continued pause in trial
enrollment during the three months ended June 30, 2022.


Personnel-related costs, including salaries, bonuses, benefits and other
compensation-related costs were $5.8 million and stock-based compensation
expense was $3.4 million for the three months ended June 30, 2022, compared to
personnel-related costs of $4.1 million and stock-based compensation expense of
$1.2 million for the three months ended June 30, 2021. The increase in
personnel-related costs of $3.9 million was primarily due to the hiring of
additional individuals to support the development of our product candidates,
including an increase in stock-based compensation expense of $2.2 million.


The increase in external discovery-related and other costs of $3.0 million was
primarily due to the $1.3 million quarterly fee under the Adimab Collaboration
Agreement, $0.8 million with respect to services performed and other fees under
the Adimab Assignment Agreement and the Adimab Collaboration Agreement, and $0.9
million in other external costs, including consulting services, insurance costs
and software expenditures. We did not pay a quarterly fee to Adimab under the
Adimab Collaboration Agreement during the three months ended June 30, 2021.

Acquired In-Process Research and Development Expenses

There was no IPR&D expense recognized during the three months ended June 30, 2022.



Acquired IPR&D expenses of $2.5 million for the three months ended June 30, 2021
consisted of the cost we incurred in the period under the Adimab Assignment
Agreement for a milestone payment that became due to Adimab in April 2021 upon
the dosing of the first patient in a Phase 2 clinical trial evaluating
adintrevimab for the prevention of COVID-19. The amount of this contingent
payment was recognized as an IPR&D expense based on the nature of the associated
assets acquired from Adimab on the date the milestone achievement became
probable.

Total selling, general and administrative expenses $ 14,620 $

7,124 $ 7,496




Selling, general and administrative expenses were $14.6 million for the three
months ended June 30, 2022, compared to $7.1 million for the three months ended
June 30, 2021. The $7.5 million increase in selling, general and administrative
expenses was primarily due to the following:

Personnel-related costs, including salaries, bonuses, benefits and other compensation-related costs were $2.8 million and stock-based compensation expense was $3.0 million for the three months ended June 30, 2022, compared to


                                       29
--------------------------------------------------------------------------------


personnel-related costs of $1.9 million and stock-based compensation expense of
$2.2 million for the three months ended June 30, 2021. The increase in
personnel-related costs of $1.7 million was primarily due to the hiring of
additional individuals to support our operations as we began operating as a
public company, including an increase in stock-based compensation expense of
$0.8 million.


The increase in professional services and consultant fees of $5.3 million was
primarily due to costs incurred as we began operating as a public company,
including expenses related to corporate governance matters, director and officer
insurance premiums, audit and other fees.

Other costs remained relatively consistent between periods.

Other Income (Expense), Net



Other income (expense), net was $0.8 million and less than $0.1 million for the
three months ended June 30, 2022 and 2021, respectively, consisting primarily of
interest earned on invested cash balances.

Research and development expenses were $129.2 million for the six months ended
June 30, 2022, compared to $69.2 million for the six months ended June 30, 2021.
The $60.0 million increase in research and development expenses was primarily
due to the following:


The increase in direct costs related to our adintrevimab program of $42.1
million was primarily due to overall increases in our contract manufacturing and
contract research expenses of $28.5 million related to the production of
materials for use in our clinical trials and nonclinical studies for the
adintrevimab program, as well as supply for use under a potential EUA for
adintrevimab, procured from WuXi, our sole-source supplier of drug substance and
drug product, and clinical trial expenses of $14.4 million related to ongoing
activities for our clinical trials for the adintrevimab program, partially
offset by lower costs due to a pause in trial enrollment during the six months
ended June 30, 2022. These overall increases were offset by a decrease in other
external research and development costs of $0.8 million.


Personnel-related costs, including salaries, bonuses, benefits and other
compensation-related costs were $12.2 million and stock-based compensation
expense was $6.5 million for the six months ended June 30, 2022, compared to
personnel-related costs of $6.2 million and stock-based compensation expense of
$1.4 million for the six months ended June 30, 2021. The

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


increase in personnel-related costs of $11.1 million was primarily due to the
hiring of additional individuals to support the development of our product
candidates, including an increase in stock-based compensation expense of $5.1
million.


The increase in external discovery-related and other costs of $6.7 million was
primarily due to the $2.6 million quarterly fee under the Adimab Collaboration
Agreement, $1.4 million with respect to services performed and other fees under
the Adimab Assignment Agreement and the Adimab Collaboration Agreement, $0.6
million related to services performed under the Research Collaboration and
License Agreement with TSRI, and $2.1 million in other external costs, including
professional and consulting services, insurance costs and software expenditures.
We did not pay a quarterly fee to Adimab under the Adimab Collaboration
Agreement during the six months ended June 30, 2021.

Acquired In-Process Research and Development Expenses

There was no IPR&D expense recognized during the six months ended June 30, 2022.



Acquired IPR&D expenses of $3.5 million for the six months ended June 30, 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 for the prevention of COVID-19 and 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. The amounts of these contingent payments were
recognized as an IPR&D expense based on the nature of the associated assets
acquired from Adimab on the date the milestone achievement became probable.

Total selling, general and administrative expenses $ 23,324 $ 10,695 $ 12,629




Selling, general and administrative expenses were $23.3 million for the six
months ended June 30, 2022, compared to $10.7 million for the six months ended
June 30, 2021. The $12.6 million increase in selling, general and administrative
expenses was primarily due to the following:


Personnel-related costs, including salaries, bonuses, benefits and other
compensation-related costs were $5.6 million and stock-based compensation
expense was $1.8 million for the six months ended June 30, 2022, compared to
personnel-related costs of $3.0 million and stock-based compensation expense of
$2.5 million for the six months ended June 30, 2021. The increase in
personnel-related costs of $1.9 million was primarily due to the hiring of
additional individuals to support our operations as we began operating as a
public company, partially offset by the reversal of stock-based compensation
expense related to the forfeiture of stock options in conjunction with the
resignation of our former Chief Executive Officer and President.


The increase in professional services and consultant fees of $10.0 million was
primarily due to costs incurred as we began operating as a public company,
including expenses related to corporate governance matters, director and officer
insurance premiums, audit and other fees.

Other costs remained relatively consistent between periods.

Other Income (Expense), Net



Other income (expense), net was $0.8 million and less than $0.1 million for the
six months ended June 30, 2022 and 2021, respectively, consisting primarily of
interest earned on 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 or government supply contracts, 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.

Net (decrease) increase in cash and cash equivalents $ (67,339 ) $ 277,521




Operating Activities

During the six months ended June 30, 2022, operating activities used $116.4
million of cash, primarily due to our net loss of $151.7 million, partially
offset by non-cash charges of $8.8 million. Net cash provided by changes in our
operating assets and liabilities consisted of a $8.4 million increase in
accounts payable, partially offset by a $18.8 million decrease in prepaid
expenses and other current assets, a $3.7 million decrease in accrued expenses,
and a $3.0 million decrease in other non-current assets. The increase in
accounts payable and decrease in accrued expenses was primarily due to the
timing of vendor invoicing and payments. The decrease in prepaids expenses and
other current assets and in other non-current assets was primarily due to our
utilization of WuXi manufacturing deposits.

During the six months ended June 30, 2021, operating activities used $57.3
million of cash, primarily resulting from our net loss of $83.4 million,
partially offset by non-cash charges of $4.0 million. Net cash provided by
changes in our operating assets and liabilities for the six months ended June
30, 2021 consisted primarily of a $21.1 million increase in accrued expenses and
a $2.2 million increase in accounts payable, both partially offset by a $1.1
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

Net cash provided by investing activities during the six months ended June 30, 2022 primarily consisted of $49.0 million in maturities of marketable securities.

We had no cash used in or provided by investing activities for the six months ended June 30, 2021.



Financing Activities

Net cash provided by financing activities during the six months ended June 30, 2022 primarily consisted of $0.1 million from exercises of stock options.



Net cash provided by financing activities during the six months ended June 30,
2021 primarily consisted of $335.3 million in net proceeds from the issuance of
our Series C preferred stock in April 2021.

Funding Requirements



Our expenses could increase 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, including any
associated manufacturing activities, and potential commercialization efforts.
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 discovery, 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 of manufacturing and validation activities associated with adintrevimab and with the development and manufacturing of 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 clinical and commercial supply of our potential future 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.

As of August 15, 2022, we believe that our existing cash and cash equivalents
will enable us to fund our operating expenses and capital expenditure
requirements into the second quarter 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, 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.

Contractual Obligations and Commitments



During the three months ended June 30, 2022, there were material changes to our
contractual obligations from those described in the 2021 Form 10-K. In April
2022, the total volume of contractually binding drug substance and drug product
batches to be manufactured under the Commercial Manufacturing Agreement was
reduced to $51.6 million, a decrease of $107.8 million from the previous
commitment of minimum non-cancelable purchase obligations of $159.4 million. In
addition, the Company received a credit in the low eight-figures to offset
future services rendered by WuXi. In June 2022, we entered into a two year
noncancelable agreement for dedicated laboratory and office space in Newton,
Massachusetts. The monthly rental payments under the agreement include base rent
charges of $0.7 million per year. For additional information, see Note 8 to our
condensed consolidated financial statements appearing in this Quarterly Report
on Form 10-Q.

Critical Accounting Policies and Significant Judgments and Estimates



Our financial statements are prepared in accordance with generally accepted
accounting principles in the United States. The preparation of our financial
statements and related disclosures requires us to make estimates, assumptions
and judgments that affect the reported amount of assets, liabilities, revenue,
costs and expenses, and related disclosures. Our critical accounting policies
and estimates are described under the heading "Management's Discussion and
Analysis of Financial Condition and Results of Operations-Critical Accounting
Policies and Significant Judgments and Estimates" in our 2021 Form 10-K. If
actual results or events differ materially from the estimates, judgments and
assumptions used by us in applying these policies, our reported financial
condition and results of operations

                                       33
--------------------------------------------------------------------------------

could be materially affected. There have been no significant changes to our critical accounting policies and estimates from those described in the 2021 Form 10-K, except as disclosed in Note 2 to our condensed consolidated financial statements appearing elsewhere in this Quarterly Report on Form 10-Q.

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 condensed consolidated financial statements appearing elsewhere
in this Quarterly Report on Form 10-Q.

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.
