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

Overview



We are a clinical-stage pharmaceutical company with a mission to discover,
develop and ultimately deliver medicines that are transformational for patients.
Our company was formed in October 2020 to pursue our mission within a unique,
at-scale asset-centric operating model in a capital efficient manner. We refer
to this concept as "asset-centricity." On January 29, 2021, we acquired 11
pre-revenue, development stage biotechnology companies as direct subsidiaries
(together referred to as the "Centessa Subsidiaries"), and in June 2021, we
completed an IPO. Since early 2022, we have substantially changed how we manage
the Centessa Subsidiaries, and where applicable, we have reorganized their
assets into individual focused pipeline programs unified under the Centessa
Pharmaceuticals corporate brand.

We are advancing the registrational program for SerpinPC, our most advanced
product candidate, for the treatment of HB. This registrational program includes
a set of studies with multiple components. If the data from the registrational
program are positive, we aim to submit a BLA to the FDA as well as potential
additional applications worldwide. While the initial focus of our ongoing
clinical development program is HB, with and without inhibitors, we believe
SerpinPC has the potential to treat all types of hemophilia regardless of
severity or inhibitor status and it may also prevent bleeding associated with
other bleeding disorders. We continue to assess registrational plans for HA.

Following clearance of our IND application from the FDA in January 2023, we
initiated a Phase 1/2a first-in-human, clinical trial of LB101 for the treatment
of solid tumors and dosed the first subject in March 2023. We look to this study
to provide validation to further advance LB101 and our LockBody technology
platform. In addition, we continue to progress earlier stage development
programs focused on high-value indications where there is unmet need, including
ORX750 for the treatment of NT1, with potential expansion into NT2 and other
sleep disorders, and MGX292 for the treatment of PAH.

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. 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. As a result, (1) earlier in 2022, we discontinued the
development of the following programs: lixivaptan in ADPKD; ZF874 in AATD; a
dual-STAT3/5 degrader program in AML; all programs associated with PearlRiver
including the small molecule EGFR Exon20 insertion mutation inhibitor program
and the C797S mutation inhibitor program for the treatment of NSCLC; (2) we
divested PearlRiver in December 2022; and, (3) we evaluated strategic options
for imgatuzumab, an anti-EGFR mAb; and subsequently divested this program in
early January 2023 through a company divestment of Pega-One. Additionally, in
December 2022, as a result of protocol defined stopping criterion having been
met, we suspended dosing in the multiple ascending dose (MAD) stage of the Phase
1 study of CBS001, a neutralizing therapeutic mAb to the inflammatory membrane
form of LIGHT for inflammatory / fibrotic diseases. We recently determined to
deprioritize CBS001 and have paused all development activities pending strategic
review. We are evaluating strategic partnerships to progress CBS004, a
therapeutic mAb targeting BDCA-2 for the potential treatment of autoimmune
diseases, into the clinic.

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, we have devoted substantially all of our
resources to acquiring and developing product and technology rights, conducting
research and development in our discovery and enabling stages, in our clinical
and preclinical trials and raising capital. We have incurred recurring losses
and negative cash flows from operations since inception and have funded
operations primarily through the sale and issuance of our equity securities. 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. We expect 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 we advance the preclinical and clinical development of product
candidates; perform research activities as we seek to discover and develop
additional programs and product candidates; carry out maintenance, expansion
enforcement, defense, and protection of our intellectual property portfolio; and
hire additional research and development, clinical and commercial personnel.
Further, inflation may affect our use of capital resources by increasing our
cost of labor, research, manufacturing and clinical trial expenses. Based on our
current
                                      117

operating model and development plan, we expect our cash and cash equivalents as
of December 31, 2022 of $393.6 million, to fund our operations into 2026 without
drawing on the remaining available tranches under the Oberland Capital financing
agreement.

Covid-19 Update

We are continuing to proactively monitor the COVID-19 global pandemic, including
the mutating Omicron variants, to assess the potential impact on our business,
and to seek to avoid any unnecessary potential delays to our programs. At this
time, our clinical programs and research activities remain largely on track,
with some modest delays in clinical trial enrollment rates and supply chain
activities for investigational clinical trial material. 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. 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). Immediately following the
acquisition of the Centessa Subsidiaries, Centessa Pharmaceuticals plc consisted
of approximately 20 legal entities, inclusive of the parent company and all
indirect subsidiaries.

Revenues



We have not generated any revenue. Our 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, we are 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") for active and discontinued programs, as well as investigative sites and consultants that conduct preclinical studies and clinical trials;

•expenses incurred under agreements with contract manufacturing organizations ("CMOs"), including committed costs for discontinued programs, 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 our business model. Product
candidates in later stages of clinical development will generally have higher
development costs than those in earlier stages of clinical development,
                                      118

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

primarily due to the increased size and duration of later-stage clinical trials.
We expect 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 our current or future product candidates is highly
uncertain. At this time, we 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 us or its
investigators to commence our clinical trials, or in our 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;

•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.



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

We 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 us to conduct clinical trials beyond those that are
currently anticipated, or if we experience significant delays in enrollment in
any clinical trials, we could be required to expend significant additional
financial resources and time on the completion of clinical development. Product
commercialization will take several years, and we expect to spend a significant
amount in development costs.

Research and Development Tax Incentives



We participate 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. In addition, unless
our subsidiaries qualify for an exemption, there are limitations to how much tax
incentive can be claimed. This limitation is calculated as the total of the
Company's relevant expenditure on employees in the period, multiplied by 300%,
plus £20,000.

General and Administrative Expense

General and administrative expense consists primarily of personnel expenses, including salaries and benefits for employees and share-based compensation. General and administrative expense also includes facility costs, including rent,


                                      119

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

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, we
issued CVR to former shareholders and option holders of Palladio. The CVR
represented 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 was settled through the issuance of our
ordinary shares equal to the amount of the total CVR payable based on the per
share value of ordinary shares at the milestone date. We 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 was assessed quarterly until settlement occurred in
February 2022.

Interest (Expense) Income, net



Interest (expense) income primarily consists of interest costs related to the
Note Purchase Agreement, partially offset by interest income earned from our
cash and cash equivalents.

Other (Expense) Income, net

Other (expense) income, net consists primarily of foreign currency transaction gains and losses 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 (loss)
income. 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.

December 31, 2021 were $155.1 million and $95.7 million, respectively. The
increase in 2022 compared with 2021 primarily reflected higher development costs
for our most advanced programs, including SerpinPC ($21.2 million) consistent
with the Company advancing the registrational program for SerpinPC for the
treatment of HB, and LB101 ($15.5 million), which reflected higher preclinical
costs compared to the prior year and costs related to the IND submission for
LB101 in December 2022. Additionally, costs in 2022 reflected increased
personnel costs of $16.4 million, which included employee severance costs of
approximately $3 million related to discontinuing certain research and
development programs as well as increased headcount and higher share-based
compensation expense of $6.1 million.

General and Administrative Expense

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



                                                                        Successor                            Predecessor

                                                                2022                 2021                     29, 2021
Personnel expenses                                         $     25,921          $   17,858                $          -
Legal and professional fees                                      15,060              14,831                         117

General and administrative expenses for the Company (Successor) for the twelve
months ended December 31, 2022 were $55.2 million and for the period from
January 30, 2021 through December 31, 2021 were $42.9 million. The increase in
2022 is primarily attributable to higher public company costs subsequent to the
Company's IPO in June 2021, higher personnel costs and increased costs related
to the implementation of Oracle software. The increase in personnel related
expenses included an increase in headcount and higher share-based compensation
expense of $4.1 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, 2022.

Acquired In-Process Research and Development



During the period from January 30, 2021 through December 31, 2021, in connection
with the acquisition of the Centessa Subsidiaries, 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 Contingent Value Rights



On February 18, 2022, we commenced dosing in the 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 Palladio, 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. The aggregate number of
ordinary shares, issued as ADSs, in satisfaction of such contingent value
rights, to the former shareholders and option holders of Palladio was 3,938,423.
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. We recognized a remaining $2.0 million
adjustment of fair value in its consolidated statement of operations and
comprehensive loss in its first quarter of 2022, while a corresponding fair
value adjustment of $15.1 million was recognized in our consolidated statement
of operations and comprehensive loss during the period from January 30, 2021
through December 31, 2021.

Interest Expense, net

Interest expense, net for the twelve months ended December 31, 2022 and for the
period from January 30, 2021 through December 31, 2021 was $7.0 million and $1.2
million, respectively. The increase reflected higher interest expense from the
issuance of the Note Purchase Agreement in October 2021, partially offset by
interest earned on higher cash balances.

Other Income (Expense), net



Other income (expense), net for the twelve months ended December 31, 2022 was
$2.3 million, primarily reflecting a $5.9 million gain related to remeasuring
the Note Purchase Agreement at fair value as of December 31, 2022,
                                      123

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

Table of Contents



partially offset by foreign currency transaction losses of $2.8 million. The
unrealized gain related to the Note Purchase Agreement was primarily driven by
an increase in the discount rate due to a higher risk free rate and an increase
in credit spreads. Other income (expense), net for the Company during the period
from January 30, 2021 through December 31, 2021 was $(4.4) million, largely
reflecting foreign currency transaction losses.

Liquidity and Capital Resources

Sources of Liquidity



As of December 31, 2022, we had cash and cash equivalents of $393.6 million.
Concurrent with the acquisition of the Centessa Subsidiaries by the Company
(Successor) in January 2021, we 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, we
completed our 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. We received aggregate net
proceeds of $344.1 million which includes the full exercise of the underwriters'
option.

In October 2021, we entered into a financing agreement with funds managed by
Oberland Capital, which provides us 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 us including $75.0 million, funded on
October 4, 2021, $125.0 million available in tranches of $75.0 million and $50.0
million available through September 2023 and December 2023, respectively, at our
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.

Under the financing agreement, as amended, we are required to maintain a cash
balance in an amount equal to 90% of the aggregate outstanding principal amount
of all issued Notes, as defined in the Note Purchase Agreement, that have been
issued. Also pursuant to the agreement, upon the sale of any of our assets, if
the Purchaser Agent elects to have us 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 us 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.

In July 2022, we filed a shelf registration statement (Form S-3) with the SEC,
under which we may offer and sell from time to time up to $350.0 million in the
aggregate of its ordinary shares, each of which may be represented by one
American Depositary Share; senior or subordinated debt securities; warrants to
purchase any securities that may be sold under the prospectus; units or any
combination of such securities as described in such registration statement. On
January 27, 2023, the Company entered into a sales agreement with SVB Securities
LLC ("SVB") pursuant to which the Company may offer and sell its ordinary
shares, represented by American Depositary Shares, having an aggregate offering
price of up to $125.0 million from time to time in "at-the-market" offerings
through SVB, acting as our agent (the "ATM Offering"). The Company has not sold
any ordinary shares, or American Depositary Shares, or received any proceeds
from any offerings under the ATM Offering.

We have 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.

Operating Activities

During the twelve months ended December 31, 2022, the Company (Successor) used
$200.5 million of cash in operating activities, reflecting a net loss of $216.2
million, partially offset by a noncash charge of $25.0 million for share-based
compensation.

During the period from January 30, 2021 through December 31, 2021, the Company
(Successor) used $135.1 million of cash in operating activities. Cash used in
operating activities reflected a net loss of $381.1 million, offset by a $220.5
million non-cash charge for acquired in-process research and development in
connection with the acquisition of the Centessa Subsidiaries, $15.8 million in a
non-cash change in fair value of contingent value rights and debt, $14.9 million
in non-cash share-based compensation expense, and a $(5.8) million net change in
operating assets and liabilities.

During the period from January 1, 2021 through January 29, 2021, the Centessa
Predecessor Group used $1.0 million of net cash in operating activities. Cash
used in operating activities largely reflected a net loss of $0.8 million.

Investing Activities



During the twelve months ended December 31, 2022, net cash used in investing
activities for the Company (Successor) was $0.9 million, primarily related to
the purchase of property and equipment. 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 was largely attributable to $68.0
million of cash acquired in connection with the acquisition of the Centessa
Subsidiaries, partially offset by related $4.6 million of transaction costs paid
during the period.

Financing Activities

During the twelve months ended December 31, 2022, net cash provided by financing
activities for the Company (Successor) was $0.5 million, reflecting proceeds
from the exercise of stock options partially offset by the payment of debt
issuance costs. 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.

Funding Requirements

We expect expenses to increase in connection with ongoing activities,
particularly as we continue the research and development of, continue or
initiate clinical trials of, and seek marketing approval for any current and
future product candidates. In addition, if marketing approval is obtained for
any product candidates, we expect to incur significant commercialization
expenses related to product sales, marketing, manufacturing and distribution. In
addition, inflation may affect our use of capital resources by increasing our
cost of labor, research and clinical trial expenses. Accordingly, there
                                      125

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

Table of Contents



will be a need to obtain substantial additional funding in connection with the
continuing operations. For the foreseeable future, the Centessa Subsidiaries
expect the significant majority of their funding to come from the Company. If we
are unable to raise capital when needed or on attractive terms, we would be
forced to delay, reduce or eliminate research and development programs or future
commercialization efforts.

We anticipate that our expenses will increase substantially as we:

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

•scale up clinical and regulatory capabilities;

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



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

•maintain, expand and protect the intellectual property portfolio;

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

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

•incur 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, we are 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.

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 consolidated and combined
financial statements. On an ongoing basis, an evaluation of estimates and
judgments are required, including those related to accrued research and
development expenses, the Note Purchase Agreement 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
                                      126

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

Table of Contents



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'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.

Note Purchase Agreement

As described in further detail in Note 6 -   "Debt,"   in October 2021, we
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
us including $75.0 million, funded on October 4, 2021, $125.0 million available
through 2023 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 our option and Oberland Capital. In addition, we are obligated to pay a
Milestone payment equal to 30% of the aggregate principal amount issued under
the Notes by us upon regulatory approval of any drug candidate.

We 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. We 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 our
financial statements. As we have 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



We 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.

We use 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 we have 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, we use comparable public companies as a
basis for our 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.

As there was no public market for our ordinary shares prior to the IPO, the
estimated fair value of our ordinary shares had 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.

Contractual Obligations and Other Commitments

As of December 31, 2022, 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.

We have 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 "Intellectual Property and License

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.

Incentivization Agreements



In January 2021, we established incentivization arrangements pursuant to which
certain members of the senior management teams of each subsidiary are eligible
to earn certain payments based on the attainment of corresponding milestone
performance by and/or an exit event of such subsidiary, as applicable to each
executive. As defined in the incentivization agreements, an "exit event"
includes the sale or disposition (including via an out-licensing) of all or
substantially all of the applicable subsidiary's commercially valuable assets
or, in the case of subsidiaries with more than one asset, sale or disposition of
one or more of such 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.

Emerging Growth Company and Smaller Reporting Company Status



We are an emerging growth company, as defined in the JOBS Act. Under the JOBS
Act, emerging growth companies can delay the adoption of new or revised
accounting standards issued subsequent to the enactment of the JOBS Act until
such time as those standards apply to private companies. Other exemptions and
reduced reporting requirements under the JOBS Act for emerging growth companies
include presentation of only two years of audited financial statements in a
registration statement for an initial public offering, an exemption from the
requirement to provide an auditor's report on internal controls over financial
reporting pursuant to Section 404 of the Sarbanes-Oxley Act of 2002, as amended,
an exemption from any requirement that may be adopted by the Public Company
Accounting Oversight Board regarding mandatory audit firm rotation and less
extensive disclosure about our executive compensation arrangements. We have
elected to use the extended transition period for complying with new or revised
accounting standards that have different effective dates for public and private
companies until the earlier of the date that (i) we are no longer an emerging
growth company or (ii) we affirmatively and irrevocably opt out of the extended
transition period provided in the JOBS Act.

We will remain an emerging growth company until the earliest of (i) the last day
of our first fiscal year in which we have total annual gross revenues of $1.235
billion or more, (ii) following the fifth anniversary of the closing of our
initial public offering, (iii) the date on which we are deemed to be a "large
accelerated filer," under the rules of the SEC, which means the market value of
equity securities that is held by non-affiliates exceeds $700.0 million as of
the prior June 30th and (iv) the date on which we have issued more than $1.0
billion in non-convertible debt securities during the prior three-year period.

We are also a "smaller reporting company" as defined in the Securities Exchange
Act of 1934 (the "Exchange Act"). If we are still a smaller reporting company at
the time we cease to be an emerging growth company, we may continue to rely on
exemptions from certain disclosure requirements that are available to smaller
reporting companies. Specifically, as a smaller reporting company we may choose
to present only the two most recent fiscal years of audited financial statements
in our Annual Report on Form 10-K and, similar to emerging growth companies,
smaller reporting companies have reduced disclosure obligations regarding
executive compensation.
