The following discussion and analysis should be read in conjunction with the
consolidated and combined financial statements and related notes thereto of the
Centessa Predecessor Group ("Predecessor") and Centessa Pharmaceuticals, plc
("Successor"), included elsewhere herein.

Overview

Centessa Pharmaceuticals plc ("Centessa" or "the Company") is clinical-stage
pharmaceutical company with a R&D innovation engine that aims to discover,
develop and ultimately deliver impactful medicines to patients. We seek to
pursue the best assets in a capital efficient manner with objective and
strategic decision-making to rapidly progress our programs through development.
Through our approach, we strive to deliver medicines that can lead to
significant impact for patients who are desperately in need of new treatments.

Centessa was incorporated on October 26, 2020 as a limited liability company
under the laws of England and Wales. In connection with the IPO, we
re-registered Centessa Pharmaceuticals Limited as an English public limited
company and renamed it as Centessa Pharmaceuticals plc. In January 2021, we
implemented our reimagined approach to research and development by completing
the acquisition of eleven asset-centric private biotech companies (the Centessa
Subsidiaries). Simultaneous with our acquisition of the Centessa Subsidiaries,
we completed a $250.0 million Series A convertible preferred share financing
that was comprised of $245.0 million in proceeds and the conversion of $5.0
million in convertible debt.

In June 2021, we completed an initial public offering ("IPO") of our ordinary
shares through the sale and issuance of 16,500,000 American Depositary Shares,
("ADSs"), at an initial price of $20.00 per ADS. Each ADS represents one
ordinary share with a nominal value of £0.002 per ordinary share. Following the
close of the IPO, the underwriters fully exercised their option to purchase an
additional 2,475,000 ADSs at the initial public offering price of $20.00 per
ADS. We received aggregate net proceeds of $344.1 million in connection with the
IPO and subsequent exercise of the underwriters' options after deducting
underwriting discounts, commissions and other offering expenses paid or to be
paid.

In October 2021, we entered into a financing agreement with funds managed by
Oberland Capital and drew down an initial tranche of funding in the amount of
$75.0 million. Since inception, Centessa has devoted substantially all of its
resources to acquiring and developing product and technology rights, conducting
research and development in its discovery and enabling stages, in its clinical
and preclinical trials and raising capital. The Company has incurred recurring
losses and negative cash flows from operations since inception and has funded
operations primarily through the sale and issuance of its common stock and
convertible preferred stock. The ability to generate product revenue sufficient
to achieve profitability will depend heavily on the successful development and
eventual commercialization of current or future product candidates. The Company
expects to continue to incur significant expenses and increasing operating
losses for the foreseeable future in connection with ongoing development
activities related to the portfolio of programs as Centessa Subsidiaries advance
the preclinical and clinical development of product candidates; perform research
activities as Centessa seeks to discover and develop additional programs and
product candidates; carry out maintenance, expansion enforcement, defense, and
protection of its intellectual property portfolio; and hires additional research
and development, clinical and commercial personnel. Based on the current
operating plan, the Company expects the cash and cash equivalents as of
December 31, 2021 of $595.1 million, to fund its operations into early 2024
without drawing on the remaining available tranches under the Oberland Capital
financing agreement.

Covid-19 Update

The Company is continuing to proactively monitor the ongoing COVID-19 global
pandemic, to assess the potential impact on our business, and to seek to avoid
any unnecessary potential delays to our programs. At this time, the clinical
programs and research activities remain largely on track, with some modest
delays in clinical trial enrollment rates and supply chain activities. While we
are unable to fully quantify the potential effects of this pandemic on our
future operations, including any further delays to our preclinical and clinical
programs, management continues to evaluate and to seek to mitigate risks. The
safety and well-being of employees, patients and partners remains our highest
priority.

Components of Results of Operations

Subsequent to the contribution of the Centessa Subsidiaries to Centessa, the
financial activities of Centessa and all Centessa Subsidiaries are being
presented on a consolidated basis and are denoted as "Successor" within
management's discussion and analysis of the financial statements. The historical
financial condition and results of operations for the periods presented may not
be comparable due to the difference in basis of accounting for the Centessa
Predecessor Group and Centessa Pharmaceuticals plc (previously Centessa
Pharmaceuticals Limited). Prior to the acquisition of the Centessa Subsidiaries
on January 29, 2021, the Centessa Predecessor Group consisted of three of the
acquired companies (Z Factor Limited, LockBody Therapeutics Ltd and Morphogen-IX
Limited). Following the acquisition of the Centessa Subsidiaries, Centessa
Pharmaceuticals plc consisted of 20 legal entities, inclusive of the parent
company and all indirect subsidiaries.

Revenues



The Company has not generated any revenue. The ability to generate product
revenue and to become profitable will depend upon the ability to successfully
develop, obtain regulatory approval and commercialize any current and future
product candidates. Because of the numerous risks and uncertainties associated
with product development and regulatory approval, the Company (Successor) is
unable to predict the amount or timing of product revenue.

Research and Development Expense

Research and development expenses consist primarily of costs incurred in connection with the discovery and development of the Company's clinical and preclinical programs, net of reimbursements. Research and development costs are expensed as incurred. These expenses include:

•expenses incurred to conduct the necessary preclinical studies and clinical trials required to obtain regulatory approval;

•milestone payments pursuant to the license agreements;

•personnel expenses, including salaries, benefits and share-based compensation expense for employees engaged in research and development functions;

•costs of funding research performed by third parties, including pursuant to agreements with contract research organizations ("CROs"), as well as investigative sites and consultants that conduct preclinical studies and clinical trials;

•expenses incurred under agreements with CMOs, including manufacturing scale-up expenses and the cost of acquiring and manufacturing preclinical study and clinical trial materials;

•fees paid to consultants who assist with research and development activities;

•expenses related to regulatory activities, including filing fees paid to regulatory agencies; and

•allocated expenses for facility costs, including rent, utilities, depreciation and maintenance.



Research and development activities are central to the Company's business model.
Product candidates in later stages of clinical development will generally have
higher development costs than those in earlier stages of clinical development,
primarily due to the increased size and duration of later-stage clinical trials.
The Company expects research and development expenses to increase significantly
over the next several years due to increases in personnel costs, including
share-based compensation, increases in costs to conduct clinical trials for
current product candidates and other clinical trials for future product
candidates and prepare regulatory filings for any product candidates.

The successful development of the Company's current or future product candidates
is highly uncertain. At this time, the Company cannot reasonably estimate or
know the nature, timing and costs of the efforts that will be necessary to
complete the remainder of the development of current or future product
candidates, or when, if ever, material net cash inflows may commence from
product candidates. This uncertainty is due to the numerous risks and
uncertainties associated with the duration and cost of clinical trials, which
vary significantly over the life of a project as a result of many factors,
including:

•delays in regulators or institutional review boards authorizing the Company or
its investigators to commence our clinical trials, or in the Company's ability
to negotiate agreements with clinical trial sites or CROs;

•the ability to secure adequate supply of product candidates for trials;

•the number of clinical sites included in the trials;


                                      159

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

Table of Contents

•the ability and the length of time required to enroll suitable patients;

•the number of patients that ultimately participate in the trials;

•the number of doses patients receive;

•any side effects associated with product candidates;

•the duration of patient follow-up;

•the results of clinical trials;

•significant and changing government regulations; and

•launching commercial sales of product candidates, if and when approved, whether alone or in collaboration with others.



The Company's expenditures are subject to additional uncertainties, including
the terms and timing of regulatory approvals. The Company may never succeed in
achieving regulatory approval for their product candidates.

The Company (Successor) may obtain unexpected results from clinical trials and
may elect to discontinue, delay or modify clinical trials of product candidates.
A change in the outcome of any of these variables with respect to the
development of a product candidate could mean a significant change in the costs
and timing associated with the development of that product candidate. For
example, if the European Medicines Agency ("EMA"), FDA or other comparable
regulatory authorities were to require the Company to conduct clinical trials
beyond those that are currently anticipated, or if the Company experiences
significant delays in enrollment in any clinical trials, the Company could be
required to expend significant additional financial resources and time on the
completion of clinical development. Product commercialization will take several
years, and the Company expects to spend a significant amount in development
costs.

Research and Development Tax Incentives



The Company participates in research tax incentive programs that are granted to
companies by the United Kingdom and certain European tax authorities in order to
encourage them to conduct technical and scientific research. Expenditures that
meet the required criteria are eligible to receive a tax credit that is
reimbursed in cash. Estimates of the amount of the cash refund expected to be
received are determined at each reporting period and recorded as reductions to
research and development expenses. We may not be able to continue to claim the
most beneficial payable research and development tax credits in the future if we
cease to qualify as a small or medium enterprise, based on size criteria
concerning employee headcount, turnover and gross assets.

General and Administrative Expense



General and administrative expense consists primarily of personnel expenses,
including salaries and benefits for employees in certain executive functions and
share-based compensation. General and administrative expense also includes
facility costs, including rent, utilities, depreciation and maintenance, not
otherwise included in research and development expense, as well as legal fees
related to intellectual property and corporate matters and fees for accounting
and consulting services.

Change in Fair Value of Contingent Value Rights



Change in fair value of contingent value rights reflects the fair market value
adjustment to the contingent value rights ("CVR") liability related to the
achievement of a specified development milestone for Palladio's product
candidate. In connection with the acquisition of the Centessa Subsidiaries, the
Company (Successor) issued CVR to former shareholders and option holders of
Palladio. The CVR represents the contractual rights to receive shares valued, in
aggregate, at $39.7 million upon the first patient dosed in a Phase 3 pivotal
study of lixivaptan for the treatment of ADPKD in any of the United States,
France, Germany, Italy, Spain, the United Kingdom and Japan (designated the
ACTION Study). The contingent CVR milestone will be settled through the issuance
of Centessa ordinary shares equal to the amount of the total CVR payable based
on the per share value of ordinary shares at the milestone date. The Company
(Successor) determined that the CVR should be accounted for as a liability in
accordance with ASC 480, Distinguishing Liabilities from Equity. Accordingly,
the fair value of the contingent consideration is assessed quarterly until
settlement.

Change in Fair Value of Derivative Liability



Change in fair value of derivative liability reflects the change in the fair
value of the embedded redemption feature contained in the Centessa Predecessor's
convertible term notes. As a result of the convertible notes being convertible
into a variable number of shares of the Centessa Predecessor's preferred stock,
this embedded redemption feature was bifurcated from the convertible debt at
each issuance date and recorded at fair value. The derivative has been
remeasured at each reporting period until settled. In connection with Centessa's
acquisition of the Predecessor and concurrent Series A financing event in
January 2021, the outstanding principal, interest and derivative liability were
settled in their entirety and are no longer subject to remeasurement.

Amortization of Debt Discount



Amortization of debt discount primarily consists of the bifurcation of the
embedded redemption feature associated with the Centessa Predecessor's
convertible term notes. The debt discount was amortized over the life of the
loans until they were settled in January 2021 and the Centessa Predecessor Group
recognized all unamortized debt discount.

Interest (Expense) Income, net



Interest (expense) income primarily consists of interest costs related to the
Note Purchase Agreement and interest costs related to Centessa Predecessor's
convertible term notes, partially offset by interest income earned from the
Company (Successor)'s and Predecessor's cash and cash equivalents.

Other (Expense) Income, net



Other (expense) income, net consists primarily of foreign currency transaction
gains and losses, franchise tax expense as well as the change in fair value of
the Note Purchase Agreement.

Foreign Currency Translation

The Company's financial statements are presented in U.S. dollars ("USD"), the
reporting currency of the Company. The functional currency of Centessa
Pharmaceuticals plc is USD and the functional currency of the Centessa
Subsidiaries is their respective local currency. Income and expenses have been
translated into USD at average monthly exchange rates prevailing during the
period. Assets and liabilities have been translated at the rates of exchange on
the balance sheets dates and equity accounts at their respective historical
rates. The resulting translation gain and loss adjustments are recorded directly
as a separate component of shareholders' equity as other comprehensive income
(loss). Transactions denominated in a currency other than the functional
currency are remeasured based upon the exchange rate at the date of
remeasurement with the resulting gain or loss included in the accompanying
consolidated and combined statements of operations and comprehensive loss within
Other (expense) income, net.

The functional currency of Centessa Pharmaceuticals plc had previously been
British pounds (GBP), as Centessa Pharmaceutical plc's primary activities during
formation were mostly denominated in GBP, including related transaction costs,
the acquisition of Centessa subsidiaries predominantly with operations in GBP
and the issuance of shares with a GBP nominal value as consideration in the
acquisition. Beginning in the second quarter of 2021, the functional currency of
Centessa Pharmaceuticals plc changed from GBP to USD. The change in functional
currency was the result of many factors including the completion of an IPO and
receipt of proceeds in USD which resulted in USD denominated assets exceeding
GBP denominated assets, the increase in the number of U.S.-based employees, and
the increase in costs denominated in USD, following completion of the Company's
IPO on a U.S. stock exchange (Nasdaq). Given these significant changes, the
Company considered the economic factors outlined in ASC 830, Foreign Currency
Matters and concluded that the majority of the factors supported the use of the
USD as the functional currency for Centessa Pharmaceutical plc.

The change in functional currency for Centessa Pharmaceuticals plc was applied
on a prospective basis beginning as of the second quarter of 2021 and
translation adjustments for prior periods will continue to remain as a component
of accumulated other comprehensive loss. The Company reclassified the
presentation of foreign currency gains and losses recognized first quarter of
2021 from General & administration expense to Other income (expense), net to
conform to the current period financial statement presentation.

We categorize our current programs as registrational, emerging, or exploratory.
Our R&D spend is commensurate with these three stages, with the highest spend on
the programs that have already established clinical proof of concept. For
programs in the earlier stages, we aim to implement capital-efficient plans to
reach the next set of catalysts, gating more significant spending until after we
obtain clinical proof of concept.

As part of ongoing portfolio management, we continuously review all of our
programs with the goal of assembling a pipeline of product candidates with the
potential to be first in class / best in class assets. We are not dependent on
any one program or therapeutic area within our product portfolio. Our portfolio
decisions reflect the responsibility of the management team to expeditiously
evaluate and potentially increase resources or suspend development based on
whether the product profile or data meet our criteria for further investment. In
particular, we apply our criteria to each program individually and evaluate the
merits of each program individually and not in comparison to other programs in
our pipeline. As a result, we have recently determined to: (1) discontinue the
small molecule epidermal growth factor receptor (EGFR) Exon20 insertion mutation
inhibitor program and C797S mutation inhibitor program for the treatment of
Non-Small Cell Lung Cancer (NSCLC); (2) evaluate strategic options including
potential divestment for imgatuzumab, an anti-EGFR mAb; and (3) discontinue
internal funding for the lead dual-STAT3/5 degrader program in Acute Myeloid
Leukemia (AML).

Research and development expenses for the Company (Successor) for the period
from January 30, 2021 through December 31, 2021 was $95.7 million and for the
Centessa Predecessor Group during the period from January 1, 2021 through
January 29, 2021 was $0.7 million, compared to the Centessa Predecessor Group
for the twelve months ended December 31, 2020 of $9.3 million. The increase in
2021 is primarily attributable to the growth in the portfolio of product
candidates under development following the acquisition of the Centessa
Subsidiaries in January 2021 as well as increased spending in the Centessa
Predecessor Group. Personnel expenses represent staffing costs, including
share-based
                                      163

compensation, for centralized as well as subsidiary-level teams that support
program development efforts. The increase in personnel related expenses includes
an increase in headcount and an increase in share-based compensation expense of
$5.6 million, which is primarily attributable to the equity awards issued at the
time of the acquisition and the subsequent issuances of awards through
December 31, 2021. These increases were partially offset by an increase in
research tax incentives earned as a result of the increase in qualified research
and development expenses in 2021 when compared to 2020.

Research and development expenses for the year ended December 31, 2020 were $9.3
million, compared to $4.3 million for the year ended December 31, 2019. The
increase of $5.0 million was primarily due to the increase in clinical
development of activities and expenses for the product candidates. Costs
associated with Z Factor's lead candidate, ZF874, increased $1.8 million from
$1.3 million in 2019 to $3.1 million in 2020 as Z Factor initiated its Phase 1
clinical trial and dosed its first human patient in August 2020. Costs
associated with LockBody's lead candidates, LB101 and LB201, increased $1.2
million in the aggregate from $1.3 million in 2019 to $2.5 million in 2020 as
LockBody initiated its preclinical evaluation and cell line development for
LB101 and lead optimization for LB201. Costs associated with Morphogen-IX's lead
candidate, MGX292, increased $1.9 million from $1.7 million in 2019 to $3.6
million in 2020 and primarily attributable to ongoing preclinical development in
preparation for submitting an investigational new drug application. Other
research and development expenses increased $0.3 million from $0.3 million in
2019 to $0.6 million 2020 in connection with preclinical activities and
discovery efforts for other programs. Personnel related expenses increased $0.7
million from $1.0 million in 2019 to $1.7 million in 2020 and was attributable
to the increase in research and development employee headcount. These increases
were partially offset by an increase in research tax incentives of $0.9 million
earned as a result of the increase in qualified research and development
expenses in 2020 when compared to 2019.

General and Administrative Expense

The following table summarizes the general and administrative expenses for the following periods (amounts in thousands):

General and administrative expenses for the Company (Successor) for the period
from January 30, 2021 through December 31, 2021 was $42.9 million and for the
Centessa Predecessor Group during the period from January 1, 2021 through
January 29, 2021 was $0.1 million, compared to the Centessa Predecessor Group
for the twelve months ended December 31, 2020 of $1.1 million. The increase is
primarily attributable to public company costs, the operating costs of Centessa
Pharmaceuticals plc and Centessa Pharmaceutical Inc. including professional fees
and personnel costs, and the increase in operating costs resulting from the
acquired Centessa Subsidiaries. In addition, the increase in personnel related
expenses includes an increase in headcount and an increase in share-based
compensation expense of $9.0 million, which is primarily attributable to the
immediate recognition of the certain replacement awards issued to the Centessa
Subsidiaries' employees and consultants and the options granted through December
2021 by the Company (Successor).

General and administrative expenses for the year ended December 31, 2020 were
$1.1 million, compared to $0.8 million for the year ended December 31, 2019. The
increase of $0.3 million was primarily attributable to an increase in legal and
professional fees of $0.4 million that were partially offset by a $78,000
decrease in other administrative expenses.

Acquired In-Process Research and Development

During the period from January 30, 2021 through December 31, 2021, the Company
(Successor) recognized $220.5 million of expense associated with research and
development projects of the Centessa Subsidiaries which were in-process with no
alternative future use.

Change in Fair Value of CVR

The Company (Successor) recognized $15.1 million for the change in fair value of
the contingent value right for the period from January 30, 2021 through
December 31, 2021. The change was attributable to a fair market value adjustment
from the initial fair value of $22.6 million at the date of acquisition of the
Centessa subsidiaries in January 2021 to the fair value at December 31, 2021 of
$37.7 million. On February 18, 2022, the milestone which triggers the CVR
entitlement was achieved. See Note 13 -   "Subsequent Events"  .

Interest (Expense) Income, net and Debt Issuance Costs



Interest (expense) income, net for the Company (Successor) for the period from
January 30, 2021 through December 31, 2021 was $(1.2) million, driven by
interest expense from the issuance of the Note Purchase Agreement in October
2021, partially offset by interest earned on larger cash balances due to the
Series A financing in January 2021 and the IPO in June 2021. Additionally, as
the Company has elected to account for the Note Purchase Agreement under the
fair value option, debt issuance costs of $1.3 million were immediately
expensed.

Amortization of Debt Discount



Amortization of debt discount for the Centessa Predecessor Group was $37
thousand and $0.3 million during the period from January 1, 2021 through January
29, 2021 and for the twelve months ended December 31, 2020, respectively and was
attributable to the convertible term loans. The loans were settled in January
2021 at which point all unamortized debt discounts were immediately recognized
by the Centessa Predecessor Group.

The Predecessor Group recognized $0.1 million of amortization of debt discount
for the year ended December 31, 2019 compared to $0.3 million for the year ended
December 31, 2020. The $0.2 million increase is attributable to the additional
principal borrowings in 2020 and related bifurcated redemption feature that was
recorded as a debt discount and subsequently amortized.

Other (Expense) Income, net



Other (expense) income, net for the Company (Successor) for the period from
January 30, 2021 through December 31, 2021 was $(4.4) million and was primarily
attributable to foreign currency losses of $3.6 million resulting from in part
to remeasuring the Company's USD cash and cash equivalents of Centessa
Pharmaceutical plc to GBP in the first quarter of 2021. Additionally, other
(expense) income included a $0.7 million loss related to remeasuring the Note
Purchase agreement at fair value at December 31, 2021. Other (expense) income,
net for the Centessa Predecessor Group for the period from January 1, 2021
through January 29, 2021 and for the twelve months ended December 31, 2020 was
insignificant to the Group's results of operations.

Liquidity and Capital Resources

Sources of Liquidity



As of December 31, 2021, the Company had cash and cash equivalents of $595.1
million. Concurrent with the acquisition of the Centessa Subsidiaries by the
Company (Successor) in January 2021, the Company (Successor) completed a
$250.0 million Series A convertible preferred financing that was comprised of
$245.0 million in proceeds and the $5.0 million conversion of a convertible debt
instrument. In June 2021, the Company (Successor) completed its IPO and shortly
after the close of the IPO, the underwriters exercised their option in full to
purchase an additional 2,475,000 ADSs at the initial public offering price of
$20.00 per ADS. The Company (Successor) received aggregate net proceeds of
$344.1 million which includes the full exercise of the underwriters' option.

In October 2021, the Company entered into a financing agreement with funds
managed by Oberland Capital, which provides the Company additional funds to
further scale up our development activities and to enhance balance sheet
flexibility for potential pipeline extension. Under the terms of the agreement,
Oberland Capital will purchase up to $300.0 million of 6-year, interest-only
(initial interest rate is 8.0% per annum), senior secured notes from the Company
including

$75.0 million, funded on October 4, 2021, $125.0 million available in tranches
of $75 million and $50 million within 24 months at the Company's option, and
$100.0 million available to fund M&A, in-licensing, or other strategic
transactions, at the option of the Company and Oberland Capital.

On February 11, 2022, Centessa Pharmaceuticals plc, as issuer, and certain of
the Company's wholly owned subsidiaries, as guarantors (the "Guarantors"),
entered into an Amendment to Note Purchase Agreement (the "Amendment") with
Three Peaks Capital Solutions Aggregator Fund (the "Purchaser"), and Cocoon SA
LLC (the "Purchaser Agent"), an affiliate of Oberland Capital Management LLC, as
agent for the Purchaser to modify the Note Purchase Agreement (the "Note
Purchase Agreement"), dated as of October 1, 2021 by and among the Company, the
Guarantors, the Purchaser and the Purchaser Agent.

Under the terms of the Amendment, the Company acknowledged the existence of
certain Events of Default, including the delivery by the Company of a landlord
consent after the required delivery date of October 31, 2021 and the entry by a
subsidiary of the Company into a Research Collaboration and License Agreement
without the prior consent of Purchaser Agent; as well as other non-financial,
administrative-related defaults. Under the Note Purchase Agreement, Events of
Default may entitle the lenders to default interest, penalties and the ability
to terminate the facility and to accelerate repayment of any outstanding loans
in full. Pursuant to the Amendment, the lenders agreed to waive such Events of
Default.

Pursuant to the Amendment, the Purchaser and the Purchaser Agent have also
agreed to waive the requirement to obtain the consent of a certain licensee and
waive certain of the insurance requirements contained in the Note Purchase
Agreement. The Amendment also provides that the Company is required to maintain
a cash balance in an amount equal to 75% of the aggregate outstanding principal
amount of all issued Notes, as defined in the Note Purchase Agreement, that have
been issued on and from February 11, 2022. Also pursuant to the Amendment, the
date for the Third Purchase Date, as defined in the Note Purchase Agreement, and
the Commitment Termination Date were extended to December 31, 2023. The
Amendment also provides that upon the sale of any of the Company's or any of its
subsidiary's assets, if the Purchaser Agent elects to have the Company
repurchase the notes, such repurchase amounts will be subject to a $100 million
deductible such that the Purchaser Agent will not collect any repurchase amounts
until $100 million has been received by the Company from such sale event. In
addition, the reduced payment cap that is triggered by the Purchaser Agent
opting into a repayment in the event of an asset sale, extends to the second
loan tranche, if drawn. The effectiveness of the Amendment is subject to certain
conditions precedent and conditions subsequent.

The Company (Successor) has no other ongoing material financing commitments,
such as lines of credit or guarantees, that are expected to affect liquidity
over the next five years. The maturity date of the Oberland Capital Notes is
October 4, 2027.

Investing Activities



During the period from January 30, 2021 through December 31, 2021, net cash
provided by investing activities for the Company (Successor) was $63.3 million
and is primarily attributable to $68.0 million of cash acquired in connection
with the acquisition of the Centessa Subsidiaries, which was partially offset by
the related $4.6 million of transaction costs paid during the period and $0.2
million in purchases of property and equipment.

Financing Activities



During the period from January 30, 2021 through December 31, 2021 financing
activities for the Company (Successor) provided $660.1 million in net cash
proceeds and is primarily attributable to the sale of the Company (Successor)'s
Series A preferred shares in January 2021, the IPO in June 2021, and the
issuance of debt in October 2021, net of issuance costs. The Company (Successor)
also received $0.8 million in proceeds upon the exercise of stock options.

During the year ended December 31, 2020, financing activities for the Centessa
Predecessor Group provided $1.4 million in net cash proceeds, primarily
attributable to proceeds from convertible debt issuances. During the year ended
December 31, 2019, financing activities provided $9.0 million in net cash
proceeds and attributable to $3.8 million upon the issuance of convertible debt
and $5.2 million upon the sale and issuance of Series A convertible preferred
shares.

Funding Requirements

Following the acquisition of the Centessa Subsidiaries in January 2021, the
Company expects expenses to increase in connection with ongoing activities,
particularly as the Company continues the research and development of, continues
or initiates clinical trials of, and seeks marketing approval for any current
and future product candidates. In addition, if marketing approval is obtained
for any product candidates, the Company expects to incur significant
commercialization expenses related to product sales, marketing, manufacturing
and distribution. Furthermore, following the completion of our IPO, additional
costs associated with operating as a public company are expected. Accordingly,
there will be a need to obtain substantial additional funding in connection with
the continuing operations. If the Company is unable to raise capital when needed
or on attractive terms, it would be forced to delay, reduce or eliminate
research and development programs or future commercialization efforts.

The Company anticipates that its expenses will increase substantially as it:

•seeks to discover and develop current and future clinical and preclinical product candidates;

•scales up clinical and regulatory capabilities;

•adapts regulatory compliance efforts to incorporate requirements applicable to marketed products;



•establishes a sales, marketing and distribution infrastructure and scale up
external manufacturing capabilities to commercialize any product candidates for
which regulatory approval may be obtained;
                                      167

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

•maintains, expands and protects the intellectual property portfolio;

•hires additional internal or external clinical, manufacturing and scientific personnel or consultants;

•adds operational, financial and management information systems and personnel, including personnel to support product development efforts; and

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



Because of the numerous risks and uncertainties associated research, development
and commercialization of product candidates, the Company is unable to estimate
the exact amount of its working capital requirements. Future funding
requirements will depend on and could increase significantly as a result of many
factors, including:

•the scope, progress, results and costs of preclinical studies and clinical trials;

•the scope, prioritization and number of research and development programs;

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

•the ability to establish and maintain collaborations on favorable terms, if at all;

•the extent to which obligations to reimburse exist, or entitled to reimbursement of, clinical trial costs under collaboration agreements, if any;

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

•the costs of securing manufacturing arrangements for commercial production; and

•the costs of establishing or contracting for sales and marketing capabilities if regulatory approvals are obtained to market product candidates.



Identifying potential product candidates and conducting preclinical studies and
clinical trials is a time- consuming, expensive and uncertain process that takes
many years to complete, and may never generate the necessary data or results
required to obtain marketing approval and achieve product sales. In addition,
product candidates, if approved, may not achieve commercial success. Commercial
revenues, if any, will be derived from sales of product candidates that do not
expect to be commercially available for the next couple of years, if at all.
Accordingly, the need to continue to rely on additional financing to achieve our
business objectives will exist. Adequate additional financing may not be
available on acceptable terms, or at all.

Contractual Obligations and Other Commitments

As of December 31, 2021, other than what has been disclosed in Note 7 -


  "Commitment and contingencies"   and Note 6 -   "Debt"  , we had no material
contractual obligations and other commitments associated with contracts that are
enforceable and legally binding and that specify all significant terms,
including fixed or minimum services to be used, fixed, minimum or variable price
provisions, and the approximate timing of the actions under the contracts. On
February 7, 2022, the Company entered into a 10-year office lease for its new
corporate headquarters in Boston, Massachusetts. The fixed annual rent will be
approximately $1.6 million in 2023 and will escalate to approximately $1.9
million in Year 10.

The Company has entered into collaborative arrangements to develop and
commercialize intellectual property. These arrangements typically involve two
(or more) parties who are active participants in the collaboration and are
exposed to significant risks and rewards dependent on the commercial success of
the activities. These collaborations usually involve various activities by one
or more parties, including research and development, marketing and selling and
distribution. Often, these collaborations require upfront, milestone and royalty
or profit share payments, contingent upon the occurrence of certain future
events linked to the success of the asset in development. Amounts due to
collaborative partners related to development activities are generally reflected
as research and development expenses. See Note 10 -   "Licensing Arrangements"
as well as "Intellectual Property and License Agreements" in Item 1. Business of
this Form 10-K for additional information on these arrangements.

The contractual obligations we have disclosed do not include any potential
development, regulatory and commercial milestone payments and potential royalty
payments that we may be required to make under the various license agreements
entered into by the Centessa Subsidiaries and collaboration agreement. We
excluded these payments given that the timing of any such payments cannot be
reasonably estimated at this time.

In connection with our acquisition of the Centessa Subsidiaries in January 2021,
we issued contingent value rights, or CVR, to former shareholders and option
holders of Palladio. In total, the CVR represent the contractual rights to
receive shares valued, in aggregate, at $39.7 million upon the dosing of the
first patient in commencement of the ACTION study, a pivotal Phase 3 clinical
trial of lixivaptan for the treatment of Polycystic Kidney Disease in any of the
United States, France, Germany, Italy, Spain, the United Kingdom and Japan.

On February 18, 2022, the Company commenced dosing in its pivotal Phase 3
clinical trial evaluating lixivaptan as a potential treatment for ADPKD. Such
event was the milestone trigger for payment of contingent value rights
originally issued to the former shareholders and option holders of the Company's
subsidiary, Palladio Biosciences, Inc., in connection with its acquisition by
Centessa in January 2021. The contingent value rights entitled such holders to a
number of ordinary shares of the Company (including in the form of ADSs) in an
aggregate amount of approximately $39.7 million based on the Volume Weighted
Average Price of the Company's ADSs over the five day trading period ending on
the date of the milestone trigger. On March 8, 2022, the Company and the
representative of the contingent value rights holders agreed that 3,938,423
represents the aggregate number of ordinary shares, issued as ADSs, to be issued
in satisfaction of such contingent value rights, to the former shareholders and
option holders of Palladio Biosciences, Inc. The number of ADSs issued to
employee recipients reflected in this figure is net of tax withholding, which
the Company satisfied with cash payments to tax authorities. The ADSs were
issued in exchange for the previously-issued contingent value rights of the
Company. The Company will recognize a remaining adjustment of fair value
(approximately a $2 million charge) in its consolidated statement of operations
and comprehensive loss in its first quarter of 2022.

Incentivization Agreements



In January 2021, we established incentivization arrangements pursuant to which
certain members of the senior management teams of each predecessor entity are
eligible to earn certain payments based on the attainment of corresponding
milestone performance by and/or an exit event of such predecessor entity, as
applicable to each executive. As defined in the incentivization agreements, an
"exit event" includes the sale or disposition of all or substantially all of the
applicable subsidiary's commercially valuable assets or any sale or disposition
of the applicable subsidiary's equity which results in the purchaser of the
equity acquiring a controlling interest in the applicable subsidiary. Milestones
may include the designation of a product candidate or the attainment of
approvals, licenses, permits, certifications registrations or authorizations
necessary for the sale of a particular product candidate or related molecules in
the United States, France, Germany, Italy, Spain or the United Kingdom. The
milestone payment amount for each subsidiary is in the low eight figure range to
be divided among the members of the respective subsidiary's senior management
team and employees according to the terms of its respective incentivization
agreement. Any milestone payment earned will be payable in a lump sum within
twenty (20) days after attainment of the milestone. In addition, if a sale of a
controlling interest in a subsidiary or sale (or grant of an exclusive license)
of its respective product candidate occurs prior to attainment of the milestone
or within the three (3) year period following attainment of the milestone, an
exit payment equal in the range of single digit to low teens percentage of the
sales proceeds less any amounts previously paid as a milestone payment (if any)
and any fees, costs and expenses of the sale (excluding any earn out, milestone,
royalty payment or other contingent payments but including any escrow, holdback
or similar amount) will become due and payable to certain employees and members
of the subsidiary's senior management team. To the extent an exit event occurs
following the occurrence of an adverse event (which includes the failure to
achieve milestones within the specified time period), no exit payment will
become due unless sale proceeds are in excess of an amount in the eight-figure
range.

The incentivization agreements contain standard termination provisions providing
that the agreements shall terminate upon the occurrence of certain events, or
automatically on December 31, 2035. Other events that may trigger termination
include:

•an exit event;

•the occurrence of certain asset sales in conjunction with certain milestones; and

•the date that is three years following achievement of certain milestones.

Critical Accounting Policies



Management's discussion and analysis of its financial condition and results of
operations is based on the consolidated and combined financial statements of the
Company (Successor) and Centessa Predecessor Group which have been prepared in
accordance with U.S. generally accepted accounting principles. The preparation
of these financial statements requires estimates and judgments be made that
affect the reported amounts of assets, liabilities, and expenses and the
disclosure of contingent assets and liabilities in the combined financial
statements. On an ongoing basis, an evaluation of estimates and judgments are
required, including those related to accrued expenses, contingent consideration
                                      169

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

and share-based compensation. Estimates are based on historical experience,
known trends and events, and various other factors that are believed to be
reasonable under the circumstances, the results of which form the basis for
making judgments about the carrying values of assets and liabilities that are
not readily apparent from other sources. Actual results may differ from these
estimates under different assumptions or conditions.

While the significant accounting policies are described in more detail in Note 2
to the Company (Successor)'s consolidated and the Group's combined financial
statements, the following accounting policies are the most critical to the
judgments and estimates used in the preparation of the financial statements.

Research and Development Accruals

Research and development expenses consist primarily of costs incurred in connection with the development of product candidates. Research and development costs are expensed as incurred.



Expenses for preclinical studies and clinical trial activities performed by
third parties are accrued based upon estimates of the proportion of work
completed over the term of the individual trial and patient enrollment rates in
accordance with agreements with CROs and clinical trial sites. Estimates are
determined by reviewing external service providers as to the progress or stage
of completion of trials or services and the agreed-upon fee to be paid for such
services. However, actual costs and timing of clinical trials are highly
uncertain, subject to risks and may change depending upon a number of factors,
including the clinical development plan.

Estimates of accrued expenses are made as of each balance sheet date in the
financial statements based on facts and circumstances known at that time. If the
actual timing of the performance of services or the level of effort varies from
the estimate, an adjustment to the accrual will be made accordingly.
Nonrefundable advance payments for goods and services, including fees for
process development or manufacturing and distribution of clinical supplies that
will be used in future research and development activities, are recognized as
expense in the period that the related goods are consumed or services are
performed.

Milestone payments within the Company (Successor)'s licensing arrangements are
recognized when achievement of the milestone is deemed probable to occur. To the
extent products are commercialized and future economic benefit has been
established, commercial milestones that become probable are capitalized and
amortized over the estimated remaining useful life of the intellectual property.
In addition, royalty expenses would be accrued and sublicense non-royalty
payments, as applicable, for the amount it is obligated to pay, with adjustments
as sales are made.

Contingent Value Rights

In connection with the acquisition of Palladio, the Company (Successor) issued
contingent value rights, or CVR, to former shareholders and option holders of
Palladio. In total, the CVR represent the contractual rights to receive shares
valued, in aggregate, at $39.7 million upon the first patient dosed in a Phase 3
pivotal study of lixivaptan for the treatment of ADPKD in any of the United
States, France, Germany, Italy, Spain, the United Kingdom and Japan (designated
the ACTION Study). This contingent milestone was triggered in February 2022 and
will be settled in 2022 through the issuance of the Company (Successor)'s
ordinary shares equal to the amount of the total CVR payable based on the per
share value of ordinary shares at the milestone date.

The Company (Successor) determined that the contingent value rights should be
accounted for as a liability in accordance with ASC 480, Distinguishing
Liabilities from Equity. Accordingly, fair value of the contingent consideration
is assessed quarterly until settlement. To estimate the fair value of the CVR,
the Company (Successor) applies a cumulative probability of achieving the
clinical milestone and applied it to the potential payout.

Note Purchase Agreement



As described in further detail in Note 6 -   "Debt,"   in October 2021, the
Company entered into a Note Purchase Agreement (the "Notes") with Oberland
Capital Management LLC (Oberland Capital). Under the terms of the agreement,
amended, Oberland Capital will purchase up to $300.0 million of 6-year,
interest-only (initial interest rate is 8.0% per annum), senior secured notes
(the Notes) from the Company including $75.0 million, funded on October 4, 2021,
$125.0 million available within 24 months at the Company's option, and $100.0
million available to fund Mergers and Acquisitions ("M&A"), in-licensing, or
other strategic transactions, at the option of the Company and Oberland Capital.
In addition to interest payments on the principal, the Company is obligated to
pay certain Revenue Participation payments, starting on the date of the first
commercial sale of lixivaptan, currently a product candidate under development
by the Company, and ending on the tenth anniversary of the First Purchase Date;
as well as obligated to pay a Milestone payment
                                      170

equal to 30% of the aggregate principal amount issued under the Notes by the Company upon regulatory approval of any drug candidate.



The Company evaluated the notes and determined that the notes include embedded
derivatives that would otherwise require bifurcation as derivative liabilities.
Neither the debt instrument nor any embedded features are required to be
classified as equity. Therefore, the hybrid financial instrument comprised of
the debt host and the embedded derivative liability may be accounted for under
the fair value option. The Company elected to carry the Notes at fair value, and
the debt instrument is outside the scope of ASC 480, Distinguishing Liabilities
from Equity, and thus will be classified as a liability under ASC 470, Debt, in
the Company's financial statements. As the Company has elected to account for
the Notes under the fair value option, debt issuance costs were immediately
expensed.

The fair value of the Note Purchase Agreement represents the present value of
estimated future payments, including interest, principal as well as estimated
payments that are contingent upon the achievement of specified milestones. The
fair value of the notes is based on the cumulative probability of the various
estimated payments. The fair value measurement is based on significant Level 3
unobservable inputs such as the probability of achieving the milestones,
anticipated timelines, probability and timing of an early redemption of all
obligations under the agreement and discount rate. Any changes in the fair value
of the liability are recognized in the consolidated statement of operations and
comprehensive loss until it is settled.

Share-Based Compensation



The Company (Successor) and the Predecessor measure share-based awards at their
grant-date fair value and record compensation expense on a straight-line basis
over the vesting period of the awards. Following the completion of our IPO, the
fair value of our ordinary shares was determined based on the quoted market
price of our ADSs representing our ordinary shares. The Company (Successor) and
the Predecessor Group account for forfeitures of stock option awards as they
occur.

The Company uses the Black-Scholes option pricing model to value its stock
option awards. The expected life of the stock options is estimated using the
"simplified method," as the Company has limited historical information from
which to develop reasonable expectations about future exercise patterns and
post-vesting employment termination behavior for its stock option grants. The
simplified method is the midpoint between the vesting period and the contractual
term of the option. For share price volatility, the Company uses comparable
public companies as a basis for its expected volatility to calculate the fair
value of option grants. The risk-free rate is based on the U.S. Treasury yield
curve commensurate with the expected life of the option. Forfeitures of stock
options are recognized in the period the forfeiture occurs.

As there was no public market for our ordinary shares prior to the IPO, the
estimated fair value of our ordinary shares has been determined by our board of
directors as of the date of each option grant, with input from management,
considering third-party valuations of our ordinary shares, which were performed
contemporaneously with events which management believed would have an impact on
the valuation of our ordinary shares. Our board of directors considered various
objective and subjective factors, along with input from management, to determine
the fair value of our ordinary shares, including:

•our nascent stage of development and business strategy, including the status of research and development efforts of its product candidates and the material risks related to its business and industry;

•our results of operations and financial position, including our levels of available capital resources;

•the valuation of publicly traded companies in the life sciences and biotechnology sectors, as well as recently completed mergers and acquisitions of peer companies;

•the lack of marketability of our ordinary shares as a private company;

•the most recent price of our convertible preferred shares sold to investors in arm's length transactions and the rights, preferences and privileges of our convertible preferred shares relative to those of our ordinary shares;



•the likelihood of achieving a liquidity event for the holders of our ordinary
shares, such as an initial public offering or a sale of our, given prevailing
market conditions;

•trends and developments in our industry; and

•external market conditions affecting the life sciences and biotechnology industry sectors.

The third-party valuations of our ordinary shares that our board of directors
considered in making its determinations were performed in accordance with the
guidance outlined in the "Practice Guide", which prescribes several valuation
approaches for determining the value of an enterprise, such as cost, market and
income approaches, and various methodologies for allocating the value of an
enterprise to its capital structure and specifically the ordinary shares.
