The following discussion and analysis should be read in conjunction with
Catalyst's consolidated financial statements and related notes included
elsewhere in this Annual Report on Form 10-K. This discussion may contain
forward-looking statements based upon current expectations that involve risks
and uncertainties, including those set forth under the heading "Risk Factors"
and elsewhere in this Annual Report on Form 10-K. Actual results and the timing
of selected events discussed below could differ materially from those expressed
in, or implied by, these forward-looking statements.

Overview

F351 Asset Acquisition



On December 26, 2022, Catalyst acquired the F351 Assets from GNI Group Ltd. and
GNI Hong Kong Limited (the "Sellers") pursuant to that certain F351 Agreement,
by and among Catalyst and the Sellers. The F351 Assets include 15 issued or
pending patents and patent applications outside of the PRC, with the last
acquired issued patent expected to expire in August 2037. Under the terms of the
F351 Agreement and upon the effective time of the transactions contemplated by
the F351 Agreement, Catalyst issued to the Sellers equity interests with an
aggregate value of $35.0 million in the form of: 6,266,521 shares of the
Company's common stock and 12,340 shares of newly designated Series X
convertible preferred stock ("Catalyst Convertible Preferred Stock"), which
Catalyst Convertible Preferred Stock is convertible, upon the approval of the
stockholders of Catalyst (as further described herein) into shares of common
stock at a ratio of one (1) share of Catalyst Convertible Preferred Stock to
10,000 shares of common stock.

Subject to stockholder approval, each share of Catalyst Convertible Preferred
Stock issued under the F351 Agreement is convertible into 10,000 shares of
common stock. Pursuant to the F351 Agreement, Catalyst has agreed to hold a
stockholders' meeting, which is expected to be held in the third quarter of
2023, to submit the following matters to the Company's stockholders for their
consideration: (i) the approval of the conversion of the Catalyst Convertible
Preferred Stock into shares of common stock in accordance with Nasdaq rules, or
the Conversion Proposal, and (ii) if necessary or appropriate, the approval of
an amendment to Catalyst's certificate of incorporation to authorize sufficient
shares of common stock for the conversion of the Catalyst Convertible Preferred
Stock issued pursuant to the F351 Agreement. Following stockholder approval of
the Conversion Proposal, each share of Catalyst Convertible Preferred Stock is
convertible into shares of the Company's common stock at any time at the option
of the holder thereof, into 10,000 shares of its common stock, subject to
certain limitations, including that a holder of Catalyst Convertible Preferred
Stock is prohibited from converting shares of Catalyst Convertible Preferred
Stock into shares of its common stock if, as a result of such conversion, such
holder, together with its affiliates, would beneficially own more than a
specified percentage (to be initially set at 9.99% and thereafter adjustable by
the holder to a number between 4.99% and 19.99%) of the total number of shares
of Catalyst's common stock issued and outstanding immediately after giving
effect to such conversion.

Business Combination Agreement



On December 26, 2022, Catalyst, the Contributors, the Minority Holders and CPI
entered into the Business Combination Agreement. The Business Combination
Agreement contains the terms and conditions of the proposed business combination
pursuant to which Catalyst will acquire an indirect controlling interest in BC.
The closing of the Business Combination Agreement will be subject to stockholder
approval at a stockholder meeting expected to be held in the third quarter of
2023 and certain customary closing conditions. If the transaction is approved by
stockholders, Catalyst would issue at closing a total of up to 1,110,776,224
shares of its common stock for an indirect controlling interest in BC.

The Business Combination Agreement contains certain termination rights,
including the right for it to terminate the Business Combination Agreement to
enter into a definitive agreement for a superior proposal. Upon termination of
the Business Combination Agreement under specified circumstances, Catalyst may
be required to pay a termination fee of $2.0 million and either party, as the
case may be, may be required to reimburse the other party for reasonable
out-of-pocket fees and expenses incurred by such party in connection with the
Business Combination Agreement, up to a maximum amount of $2.0 million.

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

Contingent Value Rights Agreement



Concurrent with the signing of the Business Combination Agreement, Catalyst
entered into the CVR Agreement, pursuant to which each CVR Holder, excluding
GNI, received one CVR issued by the Company, subject to and in accordance with
the terms and conditions of the CVR Agreement, for each share of its common
stock held by such holder at the CVR Record Date. Each CVR entitles the holder
thereof to receive (i) certain cash payments from the net proceeds, if any,
related to (a) the disposition of its legacy assets within 90 calendar days
after the remainder of the Holdback Amount (as defined in the CVR Agreement) is
finally determined and received by Catalyst or (b) the resolution of certain
legal claims; provided, however, such period will be automatically extended for
any Claim (as defined in the CVR Agreement) for an additional one-year period to
the extent any Claim is appealed during the initial term, (ii) 100% of the
excess cash (net of all current or contingent liabilities, including
transaction-related expenses) retained by the Company in excess of $1.0 million
as of the closing date of the Business Combination Agreement, and (iii) 100% of
the amount actually received (net of indemnity claims, if any) by Catalyst
pursuant to the asset purchase agreement dated as of May 19, 2022, by and
between Catalyst and Vertex. The contingent payments under the CVR Agreement, if
they become payable, will become payable to the Rights Agent (as defined in the
CVR Agreement) for subsequent distribution to the CVR Holders. In the event that
no such proceeds are received, or the permitted deductions under the CVR
Agreement are greater than any such proceeds, CVR Holders will not receive any
payment pursuant to the CVR Agreement. There can be no assurance that CVR
Holders will receive any amounts. The CVRs are not transferable, except in
certain limited circumstances as provided for in the CVR Agreement, will not be
certificated or evidenced by any instrument, and will not be registered with the
SEC or listed for trading on any exchange.

Prior to the F351 acquisition, Catalyst was engaged in the research and
development of product candidates from Catalyst's protein engineering platform.
In February 2022, Catalyst announced that it engaged Perella Weinberg Partners
as a financial advisor to assist Catalyst in exploring strategic alternatives to
monetize its assets. In March 2022, Catalyst ceased research and development
activities and in May 2022, Catalyst entered into an asset purchase agreement
with Vertex, pursuant to which Vertex purchased Catalyst's complement portfolio,
including CB 2782-PEG and CB 4332, as well as its complement-related
intellectual property, including the ProTUNE™ and ImmunoTUNE™ platforms, for
$60.0 million in cash consideration. $55.0 million was received upfront and the
remaining $5.0 million was retained by Vertex as a hold-back until one year
after the closing date to satisfy certain post-closing indemnification
obligations. Any amounts received from Vertex with respect to this hold-back
will be distributed to the CVR Holders. On February 27, 2023, Catalyst signed an
asset purchase agreement with GC Biopharma Corp. ("GCBP") pursuant to which GCBP
acquired Catalyst's legacy rare bleeding disorders programs including
marzeptacog alpha activated ("MarzAA"), dalcinonacog alpha ("DalcA") and
CB-2679d-GT for a total of $6.0 million, $1.0 million payable on signing and
$5.0 million payable on February 28, 2025, subject to satisfaction of
post-closing indemnification obligations. In March 2023, Catalyst distributed
net proceeds of approximately $0.2 million to the CVR Holders. Once received,
any additional net proceeds from the transaction will be distributed to the CVR
Holders. Catalyst is also pursuing certain legal claims against a third party
related to payments under a 2016 asset purchase agreement, and any net
recoveries related to these claims will be distributed to the CVR Holders.

Financial Operations Overview

Catalyst has no drug products approved for commercial sale and has not generated any revenue from drug product sales.



Catalyst has never been profitable and has incurred significant operating losses
in each year since inception. Catalyst had net losses of $8.2 million and $87.9
million for the years ended December 31, 2022 and 2021, respectively. As of
December 31, 2022, Catalyst had an accumulated deficit of $410.9 million. As of
December 31, 2022, its cash and cash equivalents balance was $21.7 million.
Substantially all its operating losses were incurred in its research and
development programs and in its general and administrative operations.

License and Collaboration Revenue



License and collaboration revenue consists of revenue earned for performance
obligations satisfied pursuant to the License and Collaboration Agreement with
Biogen entered into in December 2019 and terminated in May 2022 (the "Biogen
Agreement"). Catalyst recognized collaboration revenue for reimbursable
third-party vendor, out-of-pocket

                                       62
--------------------------------------------------------------------------------

and personnel costs pertaining to the Biogen Agreement, of $0.8 million and $7.3 million during the years ended December 31, 2022 and 2021, respectively.



Catalyst has not generated any revenue from the sale of any drug products and
Catalyst does not expect to generate any revenue from the sale of drug products
until Catalyst obtains regulatory approval of and commercialize its product
candidates.

Cost of License and Collaboration Revenue



Cost of license and collaboration revenue consists of fees for research and
development services payable to third-party vendors and personnel costs,
corresponding to the recognition of license and collaboration revenue from
Biogen. Cost of license and collaboration revenue does not include any allocated
overhead costs. Catalyst recognized third-party vendor, out-of-pocket and
personnel costs, most of which were reimbursable, pertaining to the Biogen
Agreement of $0.8 million and $7.4 million during the years ended December 31,
2022 and 2021, respectively, and recorded such costs as cost of collaboration
revenue.

Acquired In-process Research and Development Expenses



Acquired in-process research and development ("IPR&D") expense resulted from the
acquisition of the F351 Assets in December 2022. The acquisition costs allocated
to acquire IPR&D with no alternative future use was recorded as an expense at
the acquisition date.

Research and Development Expenses



As of March 2022, Catalyst ceased the development of certain programs and during
the quarter ended June 30, 2022, Catalyst ceased all research and development
activities. Research and development expenses represent costs incurred to
conduct research, such as the discovery and development of its product
candidates. Catalyst recognizes all research and development costs as they are
incurred. Nonrefundable advance payments for goods or services used in research
and development are deferred and capitalized. The capitalized amounts are then
expensed as the related goods are delivered or services are performed, or until
it is no longer expected that the goods or services will be delivered.

Research and development expenses have traditionally consisted primarily of the following:

• employee-related expenses, which include salaries, benefits and stock-based

compensation;

• laboratory and vendor expenses, including payments to consultants and third

parties, related to the execution of preclinical, non-clinical and clinical

studies;

• the cost of acquiring and manufacturing preclinical and clinical materials

and developing manufacturing processes;

• clinical trial expenses, including costs of third-party clinical research


       organizations;


  • performing toxicity and other preclinical studies; and

• facilities and other allocated expenses, which include direct and allocated

expenses for rent and maintenance of facilities, depreciation and

amortization expense and other supplies.




The table below details its internal and external costs for research and
development for the period presented, excluding the acquired IPR&D (in
thousands). See "Current Product Development Plans" included elsewhere in this
Annual Form 10-K for further discussion of the current research and development
programs.

                                                                 Year Ended December 31,
                                                                2022                2021

Total research and development expenses (excluding IPR&D) $ 13,037

    $      68,889




                                       63

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


The largest component of total operating expenses had historically been
Catalyst's investment in research and development activities, including the
clinical and manufacturing development of its product candidates. Costs listed
for its hemophilia and complement programs above consist of clinical trial,
manufacturing and research costs. Its internal resources, employees and
infrastructure, identified above as personnel and other, are generally not
directly tied to individual product candidates or development programs. As such,
Catalyst does not maintain information regarding these costs incurred for these
research and development programs on a project-specific basis.

Since Catalyst has ceased its research and development activities, Catalyst expects its aggregate research and development expenses will continue after the Business Combination Agreement.

General and Administrative Expenses



General and administrative expenses consist of personnel costs, allocated
expenses, expenses for outside professional services, including legal, human
resources, audit and accounting services, and other general expenses. Personnel
costs consist of salaries, bonuses, benefits and stock-based compensation.
Catalyst incurs expenses associated with operating as a public company,
including expenses related to compliance with the rules and regulations of the
SEC and Nasdaq, insurance expenses, audit expenses, investor relations
activities, Sarbanes-Oxley compliance expenses and other administrative expenses
and professional services.

Gain on Disposal of Assets

Gain on disposal of assets resulted from the sale of Catalyst's complement portfolio and related intellectual property to Vertex in May 2022. The gain is presented net of the direct costs incurred to transact the sale and losses incurred in connection with the sale of Catalyst's property and equipment.

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

Research and Development Expenses



Research and development expenses, excluding the acquired IPR&D, were $13.0
million and $68.9 million during the years ended December 31, 2022 and 2021,
respectively, a decrease of approximately $55.9 million, or 81%. The decrease
was due primarily to a decrease of $23.4 million in hemophilia-related costs, a
decrease of $20.5 million in complement-related costs, a decrease of $11.1
million in personnel-related costs, and a decrease of $0.9 million in
stock-based compensation costs. Research and development expenses for the year
ended December 31, 2022 include approximately $0.6 million of severance and
other costs related to its reduction-in-force.

General and Administrative Expenses



General and administrative expenses were $17.4 million and $19.0 million during
the years ended December 31, 2022 and 2021, respectively, a decrease of
approximately $1.6 million, or 8%. The decrease was due primarily to a decrease
of $2.1 million in professional services, a decrease of $2.1 million in
personnel-related costs, partially offset by an increase of $2.2 million in
facilities and other administrative costs, which primarily related to
transaction costs incurred in connection with the Business Combination Agreement
and costs related to the Company's operating leases, an increase of $0.2 million
related to the Company's allowance for doubtful accounts, and a net increase of
$0.2 million related to settlements reached with Biogen and certain contract
service vendors. General and administrative expenses for the year ended December
31, 2022 include approximately $0.4 million of severance and other costs related
to its reduction-in-force.

Acquired In-Process Research and Development



Acquired IPR&D was $35.4 million for the year ended December 31, 2022, which
related to the acquisition of the F351 Assets in December 2022. The acquisition
cost allocated to acquire IPR&D with no alternative future use was recorded as
an expense at the acquisition date. No acquired IPR&D expenses were incurred in
2021.

Gain on Disposal of Assets, Net



Gain on disposal of assets, net was $57.2 million for the year ended December
31, 2022, which primarily consisted of a $57.4 million gain related to the sale
of its complement portfolio to Vertex in May 2022.

Interest and Other Income (Expense), Net



The $0.8 million increase in interest and other income (expense), net for the
year ended December 31, 2022 compared to the year ended December 31, 2021 was
primarily due to a $0.2 million gain recognized upon the extinguishment of a
liability and an increase in interest income.

Recent Accounting Pronouncements



Refer to Note 3, Summary of Significant Accounting Policies, to Catalyst's
consolidated financial statements included within Item 8 of this Annual Report
on Form 10-K for a description of recent accounting pronouncements adopted and
not yet adopted for the year ended December 31, 2022.

Liquidity and Capital Resources



On September 20, 2022, Catalyst paid a special, one-time cash dividend of $1.43
per share, or approximately $45.0 million, to holders of the Company's common
stock. On December 27, 2022, Catalyst declared another special cash dividend of
$0.24 per share, or approximately $7.6 million, to holders of the Company's
common stock, excluding GNI, which was paid on January 12, 2023.

As of December 31, 2022, Catalyst had $21.7 million of cash and cash
equivalents. During the year ended December 31, 2022, Catalyst had a $8.2
million net loss and $33.1 million cash used in operating activities. Catalyst
has an accumulated deficit of $410.9 million as of December 31, 2022. Catalyst
expects that its existing cash and cash equivalents are sufficient to support
its operating expenses through 2023, assuming the Company's stockholders approve
the Conversion Proposal. Catalyst's estimate as to how long the Company expects
its cash and cash equivalents to be able to fund its operations is based on
assumptions that may prove to be wrong, and it could use the Company's available
capital resources sooner than it currently expects. Further, changing
circumstances, some of

                                       65
--------------------------------------------------------------------------------

which may be beyond Catalyst's control, could cause it to consume capital significantly faster than currently anticipated, and the Company may need to seek additional funds sooner than planned.



In connection with the F351 Agreement, Catalyst issued Catalyst Convertible
Preferred Stock to GNI. Catalyst is obligated to seek stockholder approval for
the conversion of the Catalyst Convertible Preferred Stock into common stock. In
the event that the Company fails to timely hold the stockholders' meeting or
fails to obtain stockholder approval of the Conversion Proposal, then the
holders of the Catalyst Convertible Preferred Stock would be entitled to require
Catalyst to redeem, in cash, the shares of common stock underlying its Catalyst
Convertible Preferred Stock at a price per share equal to the fair value of the
common stock. If Catalyst is forced to redeem a significant amount of shares
underlying the Catalyst Convertible Preferred Stock, it could, among other
things, materially affect the Company's results of operations and cash usage
forecasts, require Catalyst to raise additional capital and impact its ability
to raise additional capital. Also, while Catalyst cannot predict the amount with
any level of certainty, there is a level of cash settlement at which, if it is
exceeded, could require Catalyst to make redemption payments in excess of its
current liquidity. Catalyst believes that its stockholders who are entitled to
vote on the Conversion Proposal at its 2023 Annual Meeting of Stockholders,
which is expected to be held in the third quarter of 2023, will vote to approve
the proposal. However, as the vote of the Company's stockholders is outside of
its control, there is substantial doubt about Catalyst's ability to continue as
a going concern within one year from the filing of this Annual Report on Form
10-K.

Catalyst expects to finance any future cash needs through a combination of
divestitures of its product candidates or other assets, equity offerings, debt
financings, collaborations, strategic alliances and licensing arrangements.
There can be no assurance as to the timing, terms or consummation of any
divestiture or financing, and the terms of any such financing may adversely
affect the Company's stockholders' rights. If Catalyst raises funds through
collaborations, strategic alliances or licensing arrangements with third
parties, it may have to relinquish valuable rights to its technologies, product
candidates or to grant licenses on terms that may not be favorable to the
Company.

The following table summarizes its cash flows for the periods presented (in
thousands):

Cash Flows from Operating Activities



Cash used in operating activities for the year ended December 31, 2022 was $33.1
million. The most significant component of its cash used was a net loss of $8.2
million. The net loss included the net gain of $57.2 million from the sale of
its complement portfolio and other assets, offset by non-cash expense primarily
related to IPR&D of $35.4 million that resulted from the acquisition of the F351
Assets in December 2022 in exchange for shares of the Company's stock,
stock-based compensation of $1.3 million, bad debt expense of $0.2 million, and
depreciation and amortization of $0.2 million. In addition, net cash outflow of
$4.9 million was attributable to the change in its net operating assets and
liabilities primarily as a result of a $6.2 million decrease in accounts
payable, and a $1.9 million decrease in accrued compensation and other accrued
liabilities, partially offset by a $1.6 million decrease in accounts and other
receivables and a $1.6 million decrease in prepaid and other current assets.

Cash used in operating activities for the year ended December 31, 2021 was $83.8
million. The most significant component of its cash used was a net loss of $87.9
million. This included non-cash expenses related to stock-based compensation of
$3.4 million and depreciation and amortization of $0.3 million. In addition,
cash inflow of $0.5 million was attributable to the change in its net operating
assets and liabilities primarily as a result of a $3.9 million decrease in
prepaid and other assets, a $1.5 million decrease in accounts receivable, and a
$0.5 million increase in accounts payable, offset by a $3.7 million decrease in
accrued compensation and other accrued liabilities and a $1.8 million decrease
in deferred revenue related to the Biogen Agreement.

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

Cash Flows from Investing Activities



Cash provided by investing activities for the year ended December 31, 2022 was
$55.4 million, due to $55.0 million in cash proceeds from the sale of its
complement portfolio to Vertex, $2.5 million due to proceeds from maturities of
investments, and $0.5 million in proceeds from the sale of property and
equipment, partially offset by $2.6 million in transaction costs related to the
sale of its complement portfolio to Vertex.

Cash provided by investing activities for the year ended December 31, 2021 was
$48.2 million, due to $49.0 million in proceeds from maturities of investments,
offset by $0.8 million used in purchases of property and equipment.

Cash Flows from Financing Activities



Cash used in financing activities for the year ended December 31, 2022 was $45.0
million, due to the special dividend issued and paid in September 2022, offset
by the issuance of a minimal amount of stock grants and option exercises.

Cash provided by financing activities for the year ended December 31, 2021 was
$49.6 million, due to $49.3 million in net proceeds from the issuance of common
stock related to its public offering in the first quarter of 2021 and $0.3
million in proceeds from ESPP purchases of common stock and stock option
exercises.

Critical Accounting Polices and Estimates



The preparation of the consolidated financial statements and related disclosures
in conformity with U.S. generally accepted accounting principles ("GAAP") and
the Company's discussion and analysis of its financial condition and operating
results require the Company's management to make judgments, assumptions and
estimates that affect the amounts reported in its consolidated financial
statements and accompanying notes. Catalyst's significant accounting policies
and methods used in preparation of the Company's consolidated financial
statements are described in Note 3, Summary of Significant Accounting Policies,
of the Notes to the Consolidated Financial Statements of this Annual Report on
Form 10-K. Management bases its estimates on historical experience and on
various other assumptions it believes to be reasonable under the circumstances,
the results of which form the basis for making judgments about the carrying
values of assets and liabilities. Actual results may differ from these
estimates, and such differences may be material.

Management believes the Company's critical accounting policies and estimates
discussed below are critical to understanding its historical and future
performance, as these policies relate to the more significant areas involving
management's judgments and estimates.

Stock-based Compensation



The Company measures the cost of employee, non-employee and director services
received in exchange for an award of equity instruments based on the fair
value-based measurement of the award on the date of grant and recognize the
related expense over the period during which an employee, non-employee or
director is required to provide service in exchange for the award on a
straight-line basis. The estimated fair value of equity awards that contain
performance conditions is expensed over the term of the award once Catalyst has
determined that it is probable that performance conditions will be satisfied.

Determining the fair value of stock-based awards at the grant date requires
judgment. The Company uses the Black-Scholes option-pricing model to determine
the fair value of stock options. The determination of the grant date fair value
of options using an option-pricing model is affected by Catalyst's assumptions
regarding a number of variables including the fair value of its common stock,
its expected common stock price volatility over the expected life of the
options, expected term of the stock option, risk-free interest rates and
expected dividends. The Company records stock-based compensation as a
compensation expense, net of the forfeited awards. Catalyst elected to account
for forfeitures when they occur. As such, the Company recognizes stock-based
compensation expense over their requisite service period based on the vesting
provisions of the individual grants. See Note 10, Stock Based Compensation, to
the consolidated financial statements included in this Annual Report on Form
10-K for more information.

F351 Asset Acquisition



On December 26, 2022, the Company completed its acquisition of the F351 Assets
in accordance with the terms of the F351 Agreement. Catalyst concluded that the
acquisition did not result in the acquisition of a business, as substantially
all of the fair value of the assets acquired was concentrated in a single
identifiable asset, the intellectual property rights (outside of the PRC) to a
clinical stage drug candidate for the treatment of liver fibrosis, or the F351
Assets. Significant judgment was required in evaluating the terms of the F351
Agreement and in valuing and recording the acquired assets at fair value as well
as determining whether the acquired IPR&D had an alternative future use.

Redeemable Convertible Preferred Stock



In connection with the F351 Asset acquisition, Catalyst issued shares of a newly
designated series of preferred stock, the Catalyst Convertible Preferred Stock,
to GNI. Each share of Catalyst Convertible Preferred Stock is convertible into
10,000 shares of common stock, subject to stockholder approval under Nasdaq
rules and subject to a beneficial ownership conversion blocker. The Company
classified the Catalyst Convertible Preferred Stock as temporary equity on the
consolidated balance sheet because if conversion to common stock is not approved
by the stockholders, the Catalyst Convertible Preferred Stock would be
redeemable at the option of the holders for cash equal to the closing price of
the common stock on last trading day prior to the holder's redemption request.
Catalyst recorded the Catalyst Convertible Preferred Stock at its relative fair
value on the date of issuance (i.e., the closing date of the F351 Asset
acquisition) and did not adjust the carrying value to its redemption value since
the Catalyst Convertible Preferred Stock is not currently redeemable, and it is
not probable that it will become redeemable in the future at the balance sheet
date. Significant judgment was required in evaluating the various rights of the
Catalyst Convertible Preferred Stock and in classifying and measuring the
Catalyst Convertible Preferred Stock as well as determining whether the Catalyst
Convertible Preferred Stock is a participating security upon issuance.

Contingent Value Rights Liability



On December 26, 2022, the Company executed the CVR Agreement, pursuant to which
each CVR Holder received one contractual CVR for each share of Catalyst common
stock held by such holder. Each CVR entitles the holder thereof to receive cash
payments in the future. Certain contingent payments under the CVR Agreement
qualified as derivatives under ASC 815, Derivatives and Hedging, and were
recorded as a liability on the balance sheet as of December 31, 2022. The CVR
liability is considered a Level 3 instrument that is initially measured at its
estimated fair value on the transaction date and subsequently remeasured at each
reporting date with changes recorded in the consolidated statement of
operations. The determination of the initial and subsequent fair value of the
CVR liability requires significant judgment by management. Changes in any of the
inputs not related to facts and circumstances existing as of the transaction
date may result in a significant fair value adjustment, which can impact the
results of operations in the period in which the adjustment is made.
