CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This Quarterly Report on Form 10-Q contains forward-looking statements within the meaning of the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. Our forward-looking statements include, but are not limited to, statements regarding our and our management team’s expectations, hopes, beliefs, intentions or strategies regarding the future. In addition, any statements that refer to projections, forecasts or other characterizations of future events or circumstances, including any underlying assumptions, are forward- looking statements. The words “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “intends,” “may,” “might,” “plan,” “possible,” “potential,” “predict,” “project,” “should,” “would” and similar expressions may identify forward-looking statements, but the absence of these words does not mean that a statement is not forward-looking. Forward-looking statements in this Quarterly Report on Form 10-Q may include, for example, statements about:

●

Zura Bio Limited (“Zura” , or “the Company”)’s success in retaining or recruiting, or changes required in, its officers, key employees or directors;

●

factors relating to the business, operations and financial performance of Zura, including, but not limited to Zura’s limited operating history;

●

the fact that Zura has not completed any clinical trials, and has no products approved for commercial sale;

●

the fact that Zura has incurred significant losses since inception, and it expects to incur significant losses for the foreseeable future and may not be able to achieve or sustain profitability in the future;

●

the fact that Zura requires substantial additional capital to finance its operations, and if it is unable to raise such capital when needed or on acceptable terms, it may be forced to delay, reduce, and/or eliminate one or more of its development programs or future commercialization efforts;

●

Zura’s ability to renew existing contracts;

●

Zura’s ability to obtain regulatory approval for its products, and any related restrictions or limitations of any approved products;

●

Zura’s ability to manage its growth effectively;

●

the impact of the COVID-19 pandemic;

●

competition and competitive pressures from other companies worldwide in the industries in which Zura operates; and

●

litigation and the ability to adequately protect Zura’s intellectual property rights.

These and other factors that could cause actual results to differ from those implied by the forward- looking statements in this Quarterly Report on Form 10-Q are more fully described under the heading “Risk Factors” in the Company’s Registration Statement on Form S-4/A filed with the SEC on February 23, 2023. New risk factors emerge from time to time and it is not possible to predict all such risk factors, nor can Zura assess the impact of all such risk factors on the business of Zura or the extent to which any factor or combination of factors may cause actual results to differ materially from those contained in any forward-looking statements. Forward-looking statements are not guarantees of performance. You should not put undue reliance on these statements, which speak only as of the date hereof. All forward-looking statements attributable to Zura or persons acting on its behalf are expressly qualified in their entirety by the foregoing cautionary statements. Zura undertakes no obligations to update or revise publicly any forward-looking statements, whether as a result of new information, future events or otherwise, except as required by law.

Table of Contents

In addition, statements of belief and similar statements reflect the beliefs and opinions of Zura on the relevant subject. These statements are based upon information available to Zura as of the date of this Quarterly Report on Form 10-Q, and while Zura believes such information forms a reasonable basis for such statements, such information may be limited or incomplete, and statements should not be read to indicate that Zura has conducted an exhaustive inquiry into, or review of, all potentially available relevant information. These statements are inherently uncertain and you should not put undue reliance on these statements, including, for example, statements about:

●

Zura’s market opportunity;

●

Zura’s public securities’ potential liquidity and trading;

●

Zura’s ability to raise financing in the future;

●

the attraction and retention of qualified directors, officers, employees and key personnel of Zura;

Zura’s ability to obtain and maintain regulatory approval of any of its product candidates;

●

Zura’s ability to research, discover and develop additional product candidates;

●

Zura’s ability to grow and manage growth profitably;

●

Zura’s ability to obtain and maintain intellectual property protection and not infringe on the rights of others;

●

●

the impact of the COVID-19 pandemic and other similar disruptions in the future; and

●

those factors set forth in documents of Zura or JATT Acquisition Corp. (“JATT”) filed, or to be filed, with SEC.

Should one or more of these risks or uncertainties materialize or should any of the assumptions made by the management of Zura prove incorrect, actual results may vary in material respects from those projected in these forward-looking statements.

All subsequent written and oral forward-looking statements concerning Zura or other matters addressed in this Quarterly Report on Form 10-Q and attributable to Zura or any person acting on their behalf are expressly qualified in their entirety by the cautionary statements contained or referred to in this Quarterly Report on Form 10-Q. Except to the extent required by applicable law or regulations, Zura undertakes no obligation to update these forward-looking statements to reflect events or circumstances after the date of this Quarterly Report on Form 10-Q or to reflect the occurrence of unanticipated events.

Zura Bio Limited

Notes to Unaudited Condensed Consolidated Financial Statements

(Tabular amounts in thousands, except share and per share data)

Organization and Description of Business

Zura Bio Limited, a Cayman Islands exempted company, formerly known as JATT Acquisition Corp (“JATT”), together with its subsidiaries (collectively, the “Company” or “Zura” or “Zura Bio”), is a clinical-stage biotechnology company advancing immunology assets into Phase 2 development programs, including ZB-168, a fully anti-IL7Ra monoclonal antibody, which it has licensed from Pfizer, Inc. (“Pfizer”), as well as torudokimab, a high affinity monoclonal antibody, and ZB-106, a bispecific antibody relating to IL-17 and BAFF, which it has licensed from Eli Lilly and Company (“Lilly”). The Company’s accounting predecessor, Zura Bio Limited (herein referred to as “Legacy Zura”), was formed in the United Kingdom (“UK”) on January 18, 2022 (“Inception”).

Business Combination

On March 20, 2023 (the “Closing Date”), the Company consummated the previously announced business combination (the “Business Combination”), pursuant to the terms of a business combination agreement (the “Business Combination Agreement”), dated as of June 16, 2022 (as amended on September 20, 2022, November 14, 2022, and January 13, 2023), by and among JATT, JATT Merger Sub, JATT Merger Sub 2, Zura Bio Holdings Ltd. (“Holdco”), and Legacy Zura. Pursuant to the Business Combination Agreement, (a) before the closing of the Business Combination, Holdco was established as a new holding company of Legacy Zura and became a party to the Business Combination Agreement; and (b) on the Closing, in sequential order: (i) Merger Sub merged with and into Holdco, with Holdco continuing as the surviving company and a wholly owned subsidiary of JATT; (ii) immediately following the Merger, Holdco merged with and into Merger Sub 2, with Merger Sub 2 continuing as the surviving company and a wholly owned subsidiary of JATT; and (iii) JATT changed its name to “Zura Bio Limited”.

The Business Combination has been accounted for as a reverse recapitalization, with Legacy Zura being the accounting acquirer and JATT as the acquired company for accounting purposes. Accordingly, all historical financial information presented in the unaudited condensed consolidated financial statements represent the accounts of Legacy Zura. The shares and net loss per share attributable to ordinary shareholders of Legacy Zura prior to the Closing Date have been retroactively restated as shares reflecting the exchange ratio established in the Business Combination Agreement.

Prior to the Business Combination, JATT’s public shares, public warrants, and public units were listed on the New York Stock Exchange (“NYSE”) under the symbols “JATT,” “JATT.WS,” and “JATT.U,” respectively. On March 20, 2023, the Company’s Class A ordinary shares (“Class A Ordinary Shares”) and public warrants began trading on the Nasdaq under the symbols “ZURA” and “ZURAW,” respectively. See Note 3, Recapitalization for additional details.

Emerging Growth Company Status

The Company is an emerging growth company, as defined in the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”). Under the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act until such time as those standards apply to private companies. The Company has elected to use the extended transition period for complying with new or revised accounting standards, and as a result of this election, the consolidated financial statements may not be comparable to companies that comply with public company Financial Accounting Standards Board (“FASB”) standards’ effective dates. The Company may take advantage of these exemptions up until the last day of the fiscal year following the fifth anniversary of an offering or such earlier time that it is no longer an emerging growth company.

Change in Fiscal Year End

On November 18, 2022, the Board of Directors approved a change in the Company’s fiscal year end from March 31 to December 31. The Company’s 2022 fiscal year began at the Company’s inception on January 18, 2022, and ended on December 31, 2022.

The change in fiscal year end also applies retrospectively to all previously issued financial statements for the periods ended March 31, 2022, June 30, 2022, and September 30, 2022.

Liquidity

The Company has incurred operating losses since inception and expects to continue to incur significant operating losses for the foreseeable future and may never become profitable. The Company has an accumulated deficit of $95.0 million and $32.1 million as of September 30, 2023 and December 31, 2022, respectively, a net loss of $8.3 million and $1.1 million for the three months ended September 30, 2023 and 2022, and a net loss of $51.9 million and $9.8 million for the nine months ended September 30, 2023 and the period ended September 30, 2022, respectively. The Company’s existing sources of liquidity as of September 30, 2023 includes $103.9 million in cash and cash equivalents.

Prior to the Business Combination, the Company historically funded operations primarily with issuances of convertible preferred shares and a promissory note. Upon the closing of the Business Combination, the Company received $56.7 million in net cash proceeds. Additionally, the Company received $75.8 million in net cash proceeds in connection with April 2023 Private Placement. The Company’s cash requirements include, but are not limited to, product manufacturing costs and working capital requirements. The Company expects such operating losses and negative cash flows from operations will continue but has sufficient liquidity to fund its operations over the next twelve months.

Summary of Significant Accounting Policies

Basis of Presentation and Principles of Consolidation

The Company’s unaudited condensed consolidated financial statements (the “condensed consolidated financial statements”) have been prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and include the accounts of its consolidated subsidiaries. Other shareholders’ interests in the Company’s subsidiaries, Z33 Bio, Inc. (“Z33”) and ZB17 LLC (“ZB17”), are shown in the condensed consolidated financial statements as redeemable noncontrolling interest and noncontrolling interest, respectively. All intercompany balances and transactions have been eliminated in consolidation.

These condensed consolidated financial statements have been prepared in accordance with U.S. GAAP applicable to interim financial statements. These financial statements are presented in accordance with the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) and do not include all disclosures normally required in annual consolidated financial statements prepared in accordance with U.S. GAAP. As such, the information included herein should be read in conjunction with Legacy Zura’s consolidated financial statements and accompanying notes as of December 31, 2022 and for the period from January 18, 2022 (date of inception) to December 31, 2022 (the “audited consolidated financial statements”) that were included in the Company’s Form 8-K filed with the SEC on April 6, 2023. In management’s opinion, these unaudited condensed consolidated financial statements have been prepared on the same basis as the annual consolidated financial statements, except for the impact of the recapitalization as described in Note 3, and reflect all adjustments, which include normal recurring adjustments, necessary for the fair statement of the Company’s financial position as of September 30, 2023 and the results of operations for the three months ended September 30, 2023 and 2022 and for the nine months ended September 30, 2023 and the period ended September 30, 2022. The results of operations for the nine months ended September 30, 2023 are not necessarily indicative of the results to be expected for the full year ending December 31, 2023 or any other future interim or annual period.

Significant Accounting Policies

Except for the addition of the Business Combination, the addition of public warrants, private placement warrants, and pre-funded warrants (collectively, the “Warrants”), the noncontrolling interest in ZB17, and the addition of stock options with market-based performance conditions, there have been no significant changes in the Company’s significant accounting policies from those that were disclosed in Note 2, Summary of Significant Accounting Policies, included in the Company’s audited consolidated financial statements that were included in the Company’s Current Report on Form 8-K filed with the SEC on April 6, 2023.

Use of Estimates

The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires the Company’s management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements, as well as the reported amounts of expenses during the reporting period. Actual results could differ from those estimates. Significant estimates and assumptions reflected in the condensed consolidated financial statements relate to and include, but are not limited to, the fair value of Class A Ordinary Shares and other assumptions used to measure share-based compensation, the fair value of redeemable noncontrolling interest, the fair value of share-based consideration transferred

for acquired assets, the fair value of contingent consideration, the fair value of the private placement warrants, and the fair value of the note payable.

Risks and Uncertainties

The Company is subject to risks common to early-stage companies in the biotechnology industry, including, but not limited to, development by the Company or its competitors of technological innovations, risks of failure of clinical studies, dependence on key personnel, protection of proprietary technology, compliance with government regulations, and ability to transition from preclinical manufacturing to commercial production of products.

The Company’s future product candidates will require approvals from the U.S. Food and Drug Administration (“FDA”) and comparable foreign regulatory agencies prior to commercial sales in their respective jurisdictions. There can be no assurance that any product candidates will receive the necessary approvals. If the Company was denied approval, approval was delayed or the Company was unable to maintain approval for any product candidate, it could have a material adverse impact on the Company.

On March 10, 2023, Silicon Valley Bank became insolvent. State regulators closed the bank and the Federal Deposit Insurance Corporation (“FDIC”) was appointed as its receiver. The Company held deposits with this bank. As a result of the actions by the FDIC, the Company’s insured and uninsured deposits have been restored.

The Company has significant cash balances at financial institutions which throughout the year regularly exceed the federally insured limit of $250,000. Any loss incurred or a lack of access to such funds could have a significant adverse impact on the Company’s financial condition, results of operations, and cash flows.

Warrants

As part of the Business Combination, the Company assumed JATT’s public warrant and private placement warrant liabilities. The public warrants were reclassified to equity following the Business Combination.

As part of the April 2023 Private Placement, the Company sold pre-funded warrants (the “Pre-Funded Warrants”) to certain accredited investors. The Pre-Funded Warrants were classified as equity instruments.

Classification of the public and pre-funded warrants as equity instruments and the private placement warrants as liability instruments is based on management’s analysis of the guidance in ASC 815. The Company measures the private placement warrant liability at fair value each reporting period with the change in fair value recorded as other (expense) income in the condensed consolidated statements of operations. The Company measured the public warrants at the fair value of the equity instruments as of the Closing Date of the Business Combination. The Company measured the pre-funded warrants at the fair value of the equity instruments as of the date of the April 2023 Private Placement. See Note 8 for additional information.

Noncontrolling Interest

During April 2023, the Company’s subsidiary, ZB17, issued a share-based payment award to a third party in connection with 2023 Lilly License representing a noncontrolling interest (See Note 6 for additional information). A noncontrolling interest in a subsidiary is considered an ownership interest in a majority-owned subsidiary that is not attributable to the parent. The Company includes noncontrolling interest as a component of total shareholders’ equity on the Company’s condensed consolidated balance sheet. The option to acquire ZB17 ownership interests do not provide the option-holder with rights to participate in the profits and losses of the subsidiary prior to the exercise of the option.

Net Loss Per Share

Basic net loss per share is computed by dividing net loss attributable to Class A Ordinary Shareholders by the weighted-average number of Class A Ordinary Shares outstanding, including Pre-Funded Warrants, during the period. Diluted net loss per share excludes the potential impact of the Company’s convertible preferred shares and options to purchase Class A Ordinary Shares because their effect would be anti-dilutive due to the Company’s net loss for the period presented. Since the Company had a net loss in the period presented, basic and diluted net loss per share are the same.

The table below provides potentially dilutive securities not included in the calculation of the diluted net loss per share because to do so would be anti-dilutive:


	September 30,	September 30,
	2023	2022
Convertible preferred shares	—	13,510,415
Shares issuable upon exercise of the Warrants to purchase Class A Ordinary Shares	12,809,996	—
Shares issuable upon exercise of options to purchase Class A Ordinary Shares	5,681,471	383,371
Shares issuable upon exercise of Z33 Series Seed Preferred Shares call option	2,000,000	—
Restricted share units	2,213,011	—
Total	22,704,478	13,893,786

Shares issuable upon the exercise of performance-based share options (“PSOs”) are excluded from the calculation of diluted net loss per share until the Company’s management deems it probable that the performance conditions will be satisfied.

Recent Accounting Pronouncements

In June 2022, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2022-03, Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions, which clarifies the guidance of measuring the fair value of equity securities subject to contractual restrictions that prohibit the sale of the equity securities. The Company early adopted this standard effective January 1, 2023. The adoption of this standard did not have a material effect on our condensed consolidated financial statements and related disclosures.

Recapitalization

As discussed in Note 1, Organization and Description of Business, on the Closing Date, JATT completed the acquisition of Legacy Zura and acquired 100% of Legacy Zura’s shares and Legacy Zura received proceeds of $56.7 million which includes proceeds from issuance of Class A Ordinary Shares upon the consummation of the Business Combination, including the Redemption Backstop shares (as defined below), proceeds from the PIPE investment (as defined below), and proceeds from the Forward Purchase Agreement (as defined below). The Company recorded $4.0 million of transaction costs, which consisted of legal, accounting, and other professional services directly related to the Business Combination. These costs were included in additional paid-in capital on the Company’s condensed consolidated balance sheet. On the Closing Date, each holder of Legacy Zura’s ordinary shares received approximately 108.083 shares of the Company’s Class A Ordinary Shares, par value $0.0001 per share. See Note 7 for additional details of the Company’s shareholders’ equity (deficit) prior to and subsequent to the Business Combination.

All equity awards of Legacy Zura were assumed by the Company and converted into comparable equity awards that are settled or exercisable for shares of the Company’s Class A Ordinary Shares. As a result, each outstanding share option was converted into an option exercisable for the Company’s Class A Ordinary Shares based on an exchange ratio of approximately 108.083 and each outstanding restricted share unit was converted into restricted units of the Company that, upon vesting, will be settled for the Company’s Class A Ordinary Shares based on an exchange ratio of approximately 108.083.

Each public and private placement warrant of JATT that was unexercised at the time of the Business Combination was assumed by the Company and represents the right to purchase one Class A Ordinary Share upon exercise of such warrant. Refer to Note 2 and Note 8 for further details.

Table of Contents

The Business Combination was accounted for as a reverse recapitalization with Legacy Zura as the accounting acquirer and JATT as the acquired company for accounting purposes. Legacy Zura was determined to be the accounting acquirer since Legacy Zura’s shareholders as a group prior to the Business Combination held the majority voting interest in the combined entity, Legacy Zura’s shareholders appointed 4 out of the 7 directors of the combined Board of Directors, Legacy Zura’s management holds certain key positions in the management of the combined entity, and Legacy Zura is the largest of the combining entities based on historical operating activity and comprises all of the ongoing operations. Accordingly, all historical financial information presented in these condensed consolidated financial statements represents the accounts of Legacy Zura. Net assets were stated at historical cost consistent with the treatment of the transaction as a reverse recapitalization of Legacy Zura. The Company’s convertible preferred shares and Class A Ordinary Shares prior to the closing of the Business Combination (as defined in Note 1) have been retroactively restated to reflect the exchange ratio of approximately 108.083 established in the Business Combination Agreement.

The number of Class A Ordinary Shares issued and outstanding immediately following the Business Combination on March 20, 2023 was:


	Shares	%
JATT Public shareholders	182,498	0.7	%
Zura shares issued – 2022 Lilly license	550,000	2.0	%
Redemption Backstop	1,301,633	4.8	%
Redemption Backstop Consideration	2,500,000	9.2	%
JATT Founders	3,450,000	12.8	%
PIPE Investment	2,009,950	7.4	%
Forward Purchase Agreement	3,000,000	11.1	%
Legacy Zura Equityholders	14,058,074	52.0	%
Total shares outstanding	27,052,155	100.0	%

PIPE Investment

Concurrently with the execution of the Business Combination Agreement, JATT entered into subscription agreements with certain “accredited investors” (as defined by Rule 501 of Regulation D) (the “PIPE Investors”) on June 16, 2022, as amended on November 25, 2022, (the “Ewon PIPE Subscription Agreement”) and March 13, 2023 (the “Eugene PIPE Subscription Agreement”), pursuant to which the PIPE Investors collectively subscribed for and agreed to purchase an aggregate of 2,009,950 JATT Class A Ordinary Shares at a purchase price of $10.00 per share for $20,099,500.

Forward Purchase Agreement and Redemption Backstop

On January 27, 2022, JATT entered into an Amended Forward Purchase Agreement (the “Forward Purchase Agreement”) with two institutional investors (the “FPA Investors”) providing that at the Closing of the Business Combination: (i) the purchasers will purchase an aggregate of 3,000,000 Class A Ordinary Shares at $10 per share for $30,000,000; and (ii) the purchase of, in a binding redemption backstop (the “Redemption Backstop”), up to an additional $15 million of Class A Ordinary Shares in the event that public Class A Ordinary Share redemptions are greater than 90% in connection with the Business Combination (the “Excess Redemptions”). On the Closing Date, FPA Investors purchased 1,301,633 JATT Class A Ordinary Shares at $10 per share for $13,016,330. In addition, the FPA Investors were issued an additional 2,500,000 Class A Ordinary Shares (“Redemption Backstop Consideration”) for no additional consideration.

Fair Value Measurements

The Company measures certain financial assets and liabilities at fair value on a recurring basis. The Company determines fair value based upon the exit price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants, as determined by either the principal market or the most advantageous market. Inputs used in the valuation techniques to derive fair values are classified based on a three-level hierarchy. These levels are:

Level 1: Inputs are unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement date;

Level 2: Inputs are observable, unadjusted quoted prices in active markets for similar assets or liabilities, unadjusted quoted prices for identical or similar assets or liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the related assets or liabilities; and

Table of Contents

Level 3: Unobservable inputs that are significant to the measurement of the fair value of the assets or liabilities that are supported by little or no market data.

Financial instruments consist of cash and cash equivalents, prepaid and other current assets, accounts payable and accrued expenses, note payable, private placement warrants, and research and development license consideration. The carrying values of the Company’s cash and cash equivalents, prepaid and other current assets, and accounts payable and accrued expenses approximate their fair value due to the short-term maturity of these instruments.

The following table presents information about the Company’s financial assets and liabilities measured at fair value on a recurring basis as of September 30, 2023 and December 31, 2022, and the fair value hierarchy of the valuation techniques utilized.


	September 30, 2023
	Level 1		Level 2		Level 3		Total
Financial assets:
Cash equivalents	$	101,950	$	—	$	—	$	101,950
Financial liabilities:
Private placement warrants	$	—	$	1,950	$	—	$	1,950

Financial liabilities:
Note payable	$	—	$	—	$	7,756	$	7,756
Research and development license consideration	$	—	$	—	$	2,634	$	2,634

There were no transfers into or out of Level 1, Level 2, or Level 3 during the three and nine months ended September 30, 2023 and the period ended December 31, 2022.

Note payable

The Company elected the fair value option to account for its Note payable to Hydra, LLC (see Note 10). The fair value of the Note payable at issuance was measured as the cash proceeds from the Note. The fair value of the Note payable subsequent to issuance was estimated using the probability-weighted expected return method (“PWERM”), whereby the total settlement obligation under the Note was determined based on the amounts payable to Hydra under various scenarios. The PWERM’s output is determined based on inputs not observable in the market, which represented a Level 3 measurement within the fair value hierarchy. The PWERM contemplated three scenarios: i) the Company consummates the Business Combination without triggering an event of default, ii) the Company triggers an event of default, and consummates the Business Combination, and iii) the Company does not consummate the Business Combination. The settlement value of each scenario was determined using a discounted cash flow model. Significant estimates in the cash flow model include the discount rate and time to repayment. As of December 31, 2022, the weighted average discount rate was 9.0%, and the weighted average time to repayment was 0.6 years, each weighted by the probability of the scenario. Upon the Closing Date of the Business Combination, the Note was remeasured to the settlement value and subsequently repaid for a total of $10.0 million. The following table provides a summary of changes in the estimated fair value of the Note:


	For the Nine
	Months Ended
	September 30, 2023
Balance at December 31, 2022	$	7,756
Remeasurement of the Note to settlement value upon the Closing of the Business Combination		2,244
Settlement of the Note		(10,000)
Balance at September 30, 2023	$	—

The Company recorded a loss on remeasurement of the Note of $2.2 million for the nine months ended September 30, 2023 within change in fair value of note payable on the condensed consolidated statement of operations.

Research and development license consideration

As consideration for the 2022 Lilly License (see Note 6), Lilly agreed to receive either 550,000 Zura Class A Ordinary Shares upon the closing of the Business Combination (subject to certain lock-up provisions) or 4,702,867 shares of Z33 Series Seed Preferred Shares (the subsidiary redeemable preferred shares) if the Business Combination was not consummated. As of December 31, 2022, the arrangement was liability classified and remeasured at fair value at each reporting date (the research and development license consideration liability). The fair value of the research and development license consideration liability was estimated using the PWERM, whereby the total settlement obligation was determined based upon the fair value of the JATT Class A Ordinary Shares, the Z33 Series Seed Preferred Shares, and the probability of the consummation of the Business Combination. As certain of the inputs to the PWERM are not observable in the market, the research and development license consideration liability represented a Level 3 measurement within the fair value hierarchy. As of December 31, 2022, the fair value of JATT Class A Ordinary Shares was determined to be $7.66 per share, a discount to the trading price due to the shares being subject to a lock-up provision. As of December 31, 2022, the fair value of Z33 Series Seed Preferred Shares was determined to be $0.15 per share.

Upon the Closing Date of the Business Combination, the liability was remeasured to its settlement value and subsequently settled through the issuance of 550,000 Class A Ordinary Shares of Zura. The aggregate fair value of the Class A Ordinary Shares of Zura issued to Lilly was determined to be $4.5 million, or $8.16 per share. The following table provides a summary of changes in the estimated fair value of the liability:


	For the Nine
	Months Ended
	September 30, 2023
Balance at December 31, 2022	$	2,634
Remeasurement of the liability to settlement value upon the Closing of the Business Combination		1,854
Settlement of the liability		(4,488)
Balance at September 30, 2023	$	—

The Company recorded a loss on the remeasurement of the research and development license consideration liability of $1.9 million for the nine months ended September 30, 2023 within research and development on the condensed consolidated statement of operations.

Private Placement Warrants

As of September 30, 2023, the Company has private placement warrants assumed in connection with the Business Combination (see Note 8). Such warrants are measured at fair value on a recurring basis. Because the transfer of private placement warrants to non-permitted transferees would result in the private placement warrants having substantially the same terms as the public warrants, the Company determined that the fair value of each private placement warrant is consistent with that of a public warrant. Accordingly, the private placement warrants are classified as Level 2 financial instruments. The following table provides a summary of changes in the estimated fair value of the private placement warrants:


Balance at December 31, 2022	$	—
Assumption of private placement warrants		1,714
Change in fair value		(177)
Balance at March 31, 2023		1,537
Change in fair value		532
Balance at June 30, 2023	$	2,069
Change in fair value		(119)
Balance at September 30, 2023	$	1,950

The Company recorded a gain from the change in fair value of the private placement warrants of $0.1 million for the three months ended September 30, 2023 and a loss of $0.2 million for the nine months ended September 30, 2023, within change in fair value of private placement warrants on the condensed consolidated statement of operations.

License Agreements

Pfizer

On March 22, 2022, the Company entered into a license agreement and a Series A-1 Subscription and Shareholder’s Agreement (collectively, the “Pfizer Agreement”) with Pfizer. Under the Pfizer Agreement, the Company acquired a license for a compound initially developed by Pfizer, in exchange for $5.0 million in cash and 2,702,083 shares (as adjusted by the exchange ratio established in the Business Combination Agreement) of the Company’s Series A-1 convertible preferred shares, representing a 20% interest in the Company. In accordance with ASC 805, the Pfizer Agreement is accounted for as an asset acquisition as substantially all of the $7.5 million value transferred to the Company was allocated to in-process research and development. On the acquisition date, the compound licensed had not yet received regulatory approval and the in-process research and development did not have an alternative use.

In addition to the consideration transferred on March 22, 2022, the Company is obligated to make 12 development and regulatory milestone payments aggregating up to $70.0 million and sales milestone payments up to an aggregate of $525.0 million based on respective thresholds of net sales of products (developed from the licensed compound) (the “Products”). In further consideration for the license, the Company will also pay an annual earned royalty at a marginal royalty rate in the mid-single digits to low double digits (less than 20%), based on thresholds of nets sales of Products. Royalties are payable on a country-by-country basis for a certain period of years or upon the later expiration of regulatory exclusivity of the Company’s Products in a country.

The Company is also subject to a potential multi-million dollar transaction payment if, within a certain period the Company has (a) certain changes in control, excluding an initial public offering or any business combination where the securities of the Company are listed on a stock exchange (e.g., a transaction with a special purpose acquisition company), or (b) the Company sublicenses or divests of its rights to the Products.

The Pfizer Agreement also has an anti-dilution provision to allow Pfizer to maintain an 18% interest in the Company, as detailed in Note 7. Immediately prior to the Closing Date of the Business Combination, additional share options and restricted share units were issued to certain employees, executives, and directors that would result in the dilution of Pfizer’s ownership in the Company. In accordance with the anti-dilution provision of the Pfizer Agreement, Pfizer was issued additional Series A-1 convertible preferred shares upon the closing of the Business Combination that were immediately converted to 267,939 Class A Ordinary Shares. In accordance with ASC 718, the Company recognized expense related to these Class A Ordinary Shares based on their grant date fair value. Following the Business Combination, the anti-dilution provision is no longer in effect.

As of September 30, 2023, the Company does not owe any amounts under the Pfizer Agreement.

Lonza

In July 2022, the Company entered into a license agreement (the “Lonza License”) with Lonza Sales AG (“Lonza”) for a worldwide non-exclusive license for Lonza’s gene expression system in exchange for varying considerations depending on a number of factors such as whether the Company enters further into manufacturing agreements with Lonza or with a third party, and whether the Company enters into sublicense agreements with third parties (including up to middle six-figure annual payments per sublicense upon commencement of a sublicense, as well as royalties of up to low-single digit percentages of net sales of certain products over a commercially standard double-digit multi-year term). The Lonza License will remain in effect until terminated. The Company is free to terminate the Lonza License at any time upon 60 days’ notice, with or without cause. Lonza may terminate the Lonza License for cause upon a breach by the Company or for other commercially standard reasons.

2022 Lilly License

On December 8, 2022, the Company’s consolidated subsidiary, Z33 Bio Inc. (“Z33”), entered into a license agreement (the “2022 Lilly License”) with Lilly pursuant to which Lilly granted Z33 an exclusive (even as to Lilly), royalty-bearing global license to develop, manufacture, and commercialize certain intellectual property owned by Lilly relating to its IL-33 compound. As consideration, the Company paid Lilly an upfront fee of $7.0 million.

As consideration for the 2022 Lilly License, Lilly agreed to receive either 550,000 Class A Ordinary Shares upon the closing of the Business Combination (subject to certain lock-up provisions) or 4,702,867 shares of Z33 Series Seed Preferred Shares (the subsidiary redeemable preferred shares) if the Business Combination was not consummated. The obligation to issue shares represents contingent consideration and is classified as a liability on the consolidated balance sheet (research and development license consideration liability) as of December 31, 2022. The liability is measured at fair value on the acquisition date and remeasured to fair value at each reporting date. Upon the Closing Date of the Business Combination, the Company issued Lilly 550,000 Class A Ordinary Shares at an aggregate fair value of $4.5 million.

The acquisition was accounted for as an asset acquisition as substantially all of the fair value of the assets acquired is concentrated in a group of similar identifiable IPR&D assets (as defined below). On the acquisition date, the compound licensed had not yet received regulatory approval and the in-process research and development did not have an alternative use. Accordingly, the Company expensed the entire cost of the 2022 Lilly License as a component of research and development in the consolidated statement of operations during the period ended December 31, 2022.

As a finder’s fee in connection with arranging the acquisition, Z33 issued to Stone Peach Properties, LLC (“Stone Peach”) 4,900,222 shares of Z33 Series Seed Preferred Shares, which is included in the measurement of the cost of the acquired asset. Zura has the right, but not the obligation to purchase up to 50% of the Series Seed Preferred Shares issued to Stone Peach at a price per share of $2.448869 for a period of two years from the date of the agreement. Stone Peach has the right, but not the obligation to sell up to 50% of the Series Seed Preferred Shares issued to Stone Peach to Zura for a price per share of $2.040724. Stone Peach may exercise its option at any time between the first anniversary and the second anniversary of the transaction. In April 2023, the Company agreed to, within six months of April 24, 2023, exercise its call option on 50% of the Z33 Series Seed Preferred Shares previously issued to Stone Peach. The Company agreed to settle its call option by issuing 2,000,000 Class A Ordinary Shares. See Note 12 for further information. The Company and Stone Peach are renegotiating the terms of the exercise of the call option.

In addition to the consideration transferred on December 8, 2022, the Company is obligated to pay $3.0 million to Lilly upon the completion of a financing by the Company with gross proceeds exceeding $100 million. The Company is further obligated to make 10 commercial, development and regulatory milestone payments up to an aggregate of $155.0 million and sales milestone payments up to an aggregate of $440.0 million based on respective thresholds of net sales of products developed from the licensed compound. The Company will also pay an annual earned royalty to Lilly at a marginal royalty rate between in the mid-single to low-double digits (less than 20%), with increasing rates based on Net Sales in the respective calendar year, based on a percentage of sales within varying thresholds for a certain period of the year. The Company will account for these contingent payments when they become due. As of September 30, 2023, none of the contingent payments were due.

2023 Lilly License

Table of Contents

of $5.8 million as well as 1,000,000 Class A Ordinary Shares issued at a fair value of $7.84 per Class A Ordinary Share. In addition, ZB17 will make a payment of $5.0 million upon the receipt of certain know-how, data, information and materials that Lilly is required to provide under the license agreement.

The acquisition was accounted for as an asset acquisition as substantially all of the fair value of the assets acquired is concentrated in a group of similar identifiable IPR&D assets. On the acquisition date, the compound licensed had not yet received regulatory approval and the in-process research and development did not have an alternative use. Accordingly, the Company expensed the entire cost of the 2023 Lilly License as a component of research and development in the condensed consolidated statement of operations during the nine months ended September 30, 2023.

As a finder’s fee for arranging the acquisition of the 2023 Lilly License, ZB17 granted to Stone Peach the right, but not the obligation, to purchase 4.99% of the fully diluted equity of ZB17 for $1.0 million (the “Stone Peach Call Right”). The Stone Peach Call Right is not exercisable until after the last patient is dosed in any single next clinical trial with ZB-106 and expires one year from the date of first indication approval for ZB-106 by the FDA or the European Medicines Agency (“EMA”). The Company recognized the Stone Peach Call Right at a grant-date fair value of $1.5 million as a component of research and development in the condensed consolidated statement of operations during the nine months ended September 30, 2023. The Stone Peach Call Right represents noncontrolling interest in the Company’s subsidiary, ZB17.

As of September 30, 2023 and December 31, 2022, the noncontrolling interest balance was $1.5 million and $-0-, respectively.

As additional consideration, Stone Peach will receive annual payments first of $0.6 million, and increasing by 10% annually, so long as the Company maintains its license for ZB-106 and beginning on May 1, 2023. The Company will account for these annual payments when they become due. The Company recognized the first $0.6 million annual payment as a component of research and development in the condensed consolidated statement of operations during the nine months ended September 30, 2023.

As a finder’s fee for arranging the acquisition of the 2023 Lilly License, the Company agreed to make a one-time milestone payment of $5.0 million to BAFFX17, Ltd (“BAFFX17”) upon the occurrence of either: (i) a change of control transaction, (ii) the closing of an issuance of equity or equity-linked securities by the Company of at least $100.0 million (iii) the consummation of a sale of assets resulting in net proceeds in excess of $100.0 million, or (iv) the Company’s fully diluted shares outstanding exceed 52,500,000 shares (on a split adjusted basis). As the Company’s fully diluted shares outstanding exceeded 52,500,000 shares prior to September 30, 2023, the $5.0 million fee was recorded in accounts payable and accrued expenses in the condensed consolidated balance sheet as of September 30, 2023 and within research and development in the condensed consolidated statement of operations for the nine months ended September 30, 2023.

In addition to the consideration transferred during the nine months ended September 30, 2023, the Company is obligated to make 4 development milestone payments to Lilly up to an aggregate of $155.0 million, and sales milestone payments up to an aggregate of $440 million based on respective thresholds of net sales of products developed from ZB-106. The Company is also obligated to pay Lilly over a multi-year period (twelve years, or upon the later expiration of regulatory exclusivity of ZB-106 in a country) an annual earned royalty at a marginal royalty rate in the mid-single digits to low-double digits, with increasing rates depending on net sales in the respective calendar year, based on a percentage of sales within varying thresholds for a certain period of years. The Company is also obligated to pay BAFFX17 a fee equal to 3% of any milestone or royalty payments due to Lilly pursuant to the terms of either the 2022 Lilly License and the 2023 Lilly License with Lilly. Upon receiving written approval from the FDA, EMA, or similar regulatory authority of the Investigational New Drug (“IND”) and commencement and the commencement of a clinical trial in the applicable jurisdiction for ZB-106, Stone Peach will also receive a one-time payment of $4.5 million. Stone Peach will also receive a one-time milestone payment of $25 million upon either (i) certain equity-related transactions, or (ii) the receipt of regulatory approval from the applicable regulatory authority for any new indication in the applicable jurisdiction. Furthermore, Stone Peach was granted a royalty of 2% of the aggregate net sales of any products developed from the Compound. The Company will account for these contingent payments when they become due. As of September 30, 2023, none of the contingent payments were due.

WuXi Biologics License

In July 2023, the Company entered into a cell line license agreement (the "Cell Line License Agreement") with WuXi Biologics and its Affiliates ("WuXi Biologics"). The Cell Line License Agreement provides the Company with a non-exclusive, worldwide, sublicensable license to certain of WuXi Biologics's know-how, cell line, and biological materials (the "WuXi Biologics Licensed Technology") to manufacture, have manufactured, use, sell and import certain products produced through the use of the cell line licensed by WuXi Biologics under the Cell Line License Agreement (the "WuXi Biologics Licensed Products"). In consideration for the license, the

Table of Contents

Company agreed to pay WuXi Biologics a non-refundable license fee of $150,000. Additionally, if the Company manufactures all of its commercial supplies of bulk drug product with a manufacturer other than WuXi Biologics or its affiliates, the Company is required to make royalty payments to WuXi Biologics in an amount equal to a fraction of a single digit percentage of global net sales of WuXi Biologics Licensed Products manufactured by a third-party manufacturer (the "Royalty"). If the Company manufactures part of its commercial supplies of the WuXi Biologics Licensed Products with WuXi Biologics or its affiliates, then the Royalty will be reduced accordingly on a pro rata basis. The Cell Line License Agreement will continue indefinitely unless terminated (i) by the Company upon three months' prior written notice and its payment of all undisputed amounts due to WuXi Biologics through the effective date of termination, (ii) by WuXi Biologics for a material breach by the Company that remains uncured for 30 days after written notice, or (iii) by WuXi Biologics if the Company fails to make a payment and such failure continues for 30 days after receiving notice of such failure.

Convertible Preferred Shares and Shareholders’ Equity (Deficit)

Prior to the Business Combination, Legacy Zura was authorized to issue Ordinary Shares and Series A-1 convertible preferred shares. The outstanding Ordinary Shares and Series A-1 convertible preferred shares of Legacy Zura are presented on the consolidated balance sheet and on the statement of changes in convertible preferred shares, redeemable noncontrolling interest and shareholders’ deficit for the annual period ended December 31, 2022.

Business Combination

Immediately prior to the Closing Date of the Business Combination, Pfizer was issued additional Series A-1 convertible preferred shares upon the closing of the Business Combination that were immediately converted to 267,939 Class A Ordinary Shares. The shares were issued in accordance with the anti-dilution provision of the Pfizer Agreement.

On the Closing Date and in accordance with the terms and subject to the conditions of the Business Combination, each Ordinary Share of Legacy Zura, par value $0.001 per share, Series A-1 convertible preferred share, outstanding option (whether vested or unvested), and restricted share unit (whether vested or unvested) were canceled and converted into a comparable number of awards that consisted of either the rights to receive or acquire the Company’s Class A Ordinary Shares, par value $0.0001 per share, as determined by the exchange ratio pursuant to the Business Combination Agreement. The exchange ratio is approximately 108.083.

On March 16, 2023, in connection with the closing of the Business Combination and effective upon the Closing Date, the Company authorized 300,000,000 Class A Ordinary Shares, par value of $0.0001 and 1,000,000 preferred shares, par value of $0.0001.

April 2023 Private Placement

On April 26, 2023, the Company entered into its second PIPE subscription agreement (the “April 2023 Private Placement”) with certain accredited investors (the “Subscribers”), whereby the Company issued 15,041,530 Class A Ordinary Shares, par value $0.0001 per share and pre-funded warrants (the “Pre-Funded Warrants”) to purchase up to 3,782,000 Class A Ordinary Shares. Each Class A Ordinary Share was sold at a price of $4.25 per Class A Ordinary Share and each Pre-Funded Warrant was sold at a price of $4.249 per Pre-Funded Warrant for an aggregate purchase price of $80.0 million. See Note 8 for further information on the Pre-Funded Warrants.

Series A-1 Convertible Preferred Shares Rights and Preferences

Conversion

Each Series A-1 convertible preferred share is convertible, at the option of the holder thereof, at any time after the date of issuance of such share, into such number shares of the Company’s Ordinary Shares, subject to adjustment.

Each Series A-1 convertible preferred share will automatically be converted into a share of the Company’s Ordinary Shares, subject to adjustment, immediately upon the occurrence of an initial public offering with a gross aggregate subscription with respect to new Ordinary Shares of greater than $50.0 million. The Ordinary Shares resulting from this conversion will rank pari passu with the existing Ordinary Shares at the time of conversion.

Table of Contents

Anti-Dilution

If the Company issues equity securities, other than pursuant to a share option plan, the Company shall issue such number of Series A-1 convertible preferred shares to Pfizer as necessary to maintain Pfizer’s ownership interest of 18%, until the Company raises in excess of $30.0 million in equity, where any capital raised above this threshold is not subject to anti-dilution.

Dividends

The holders of shares of Series A-1 convertible preferred shares are entitled to receive dividends, of profits available for distribution as determined by the Company’s board of directors with the consent of the majority of the shareholders, payable on a pro rata, pari passu basis. No dividends have been declared by the Company’s board of directors.

Liquidation

In the event of any voluntary or involuntary liquidation or return of capital (other than a conversion, redemption or purchase of shares) of the Company, the holders of the Series A-1 convertible preferred shares are entitled to receive a liquidation preference prior to any distribution to the holders of Ordinary Shares in the amount $131 per share.

Voting Rights

The holders of the Series A-1 convertible preferred shares are entitled to one vote per share, unless the Series A-1 shares are convertible into a greater number of Ordinary Shares or the holders of Series A-1 convertible preferred shares are entitled to any anti-dilution shares, in which case the holders of Series A-1 convertible preferred shares are entitled to the number of votes that the holder would be entitled upon conversion to Ordinary Shares or after the issuance of the anti-dilution shares, respectively.

Redemption Rights

The Series A-1 convertible preferred shares are not mandatorily redeemable at the option of the holder.

As of September 30, 2023, no convertible preferred shares were issued and outstanding.

Warrants

As the accounting acquirer, Zura Bio is deemed to have assumed 5,910,000 private placement warrants to purchase Class A Ordinary Shares that were held by JATT Ventures, L.P. (the “Sponsor”) at an exercise price of $11.50 and 6,899,996 public warrants to purchase Class A Ordinary Shares that were held by JATT’s public shareholders at an exercise price of $11.50. The public and private placement warrants will expire five years after the completion of the Business Combination, or earlier upon redemption or liquidation.

Public Warrants

The public warrants became exercisable into Class A Ordinary Shares commencing 30 days after the Business Combination and expire five years from the date of the Business Combination, or earlier upon redemption or liquidation. Each warrant entitles the holder to purchase one share of the Company’s Class A Ordinary Shares at a price of $11.50 per share, subject to certain adjustments.

The Company may redeem, with 30 days written notice, each whole outstanding public warrant for cash at a price of $0.01 per warrant if the Reference Value (as defined below) equals or exceeds $18.00 per share, subject to certain adjustments. The warrant holders have the right to exercise their outstanding warrants prior to the scheduled redemption date at $11.50 per share, subject to certain adjustments. If the Company calls the public warrants for redemption, the Company will have the option to require all holders that wish to exercise the Public Warrants to do so on a “cashless basis”, as described in the warrant agreement. For purposes of the redemption, “Reference Value” shall mean the last reported sales price of the Company’s Class A Ordinary Shares for any twenty trading days within the thirty trading-day period ending on the third trading day prior to the date on which notice of the redemption is given.

Private Placement Warrants

The private placement warrants were identical to the public warrants, except that the private placement warrants are not transferable, assignable or salable until 30 days after the completion of a Business Combination, subject to certain limited exceptions. Additionally,

Table of Contents

the private placement warrants are exercisable on a cashless basis and are non-redeemable so long as they are held by the initial purchasers or their permitted transferees. If the private placement warrants are held by someone other than the initial purchasers or their permitted transferees, then such warrants will be redeemable by the Company and exercisable by the warrant holders on the same basis as the public warrants.

Pre-Funded Warrants

In connection with the April 2023 Private Placement, the Company sold to accredited investors Pre-Funded Warrants to purchase up to 3,782,000 Class A Ordinary Shares at a price of $4.249 per Pre-Funded Warrant for an aggregate purchase price of approximately $16.1 million. Each Pre-Funded Warrant has an exercise price of $0.001 per Class A Ordinary Share and is exercisable for one Class A Ordinary Share at any time or times on or after April 26, 2023 until exercised in full.

As of September 30, 2023, no Warrants have been exercised or redeemed.

Share-based Compensation

On June 8, 2022, Legacy Zura’s board of directors approved two stock option plans, the UK Plan (the “UK Plan”) and the US Plan (the “US Plan”) (collectively, the “Option Plans”) which permit the granting of nonqualified share options to certain employees and directors. There were 1,501,165 Ordinary Shares available for issuance under the Option Plans, of which 383,371 Ordinary Shares were authorized for issuance under the US Plan.

On March 16, 2023, JATT’s board of directors approved the Zura Bio Limited 2023 Equity Incentive Plan (the “Equity Incentive Plan”) which became effective on the day immediately preceding the Closing Date of the Business Combination. The Equity Incentive Plan allows for the grant of share options, both incentive and nonqualified share options; SARs, alone or in conjunction with other awards; restricted shares and restricted share units (“RSUs”); incentive bonuses, which may be paid in cash, shares, or a combination thereof; and other share-based awards. On June 1, 2023, the Company’s board of directors approved an increase to the number of Class A Ordinary Shares that may be issued under the Equity Incentive Plan by an additional 5,564,315 Class A Ordinary Shares. As of September 30, 2023, a maximum of 9,594,213 Class A Ordinary Shares may be issued under the Equity Incentive Plan.

The Class A Ordinary Shares issuable under the Equity Incentive Plan are subject to an annual increase on January 1st of each calendar year beginning on January 1, 2024 and ending on and including January 1, 2029, equal to the lesser of (i) 5.0% of the aggregate number of Class A Ordinary Shares outstanding on the final day of the immediately preceding calendar year, (ii) 8,059,796 Class A Ordinary Shares or (iii) such smaller number of shares as is determined by the board.

On March 16, 2023, JATT’s board of directors approved the Zura Bio Limited 2023 Employee Stock Purchase Plan (the “ESPP”) which became effective on the day immediately preceding the Closing Date of the Business Combination. The maximum number of Class A Ordinary Shares that may be issued under the ESPP is 4,029,898, plus an aggregate number of Class A Ordinary Shares that are added under the Equity Incentive Plan on January 1st of each calendar year, beginning on January 1, 2024 and ending on and including January 1, 2029, as discussed above. The ESPP enables eligible employees of the Company and designated affiliates to purchase Class A Ordinary Shares at a discount of 15%. As of September 30, 2023, no shares have been issued under the ESPP.

Upon closing of the Business Combination, all equity awards of Legacy Zura that were issued and outstanding under the Option Plans were converted into comparable equity awards that are settled or exercisable for shares of the Company’s Class A Ordinary Shares under the Equity Incentive Plan. As a result, each of Legacy Zura’s equity awards were converted into an option to purchase Class A Ordinary Shares of the Company based on an exchange ratio of approximately 108.083.

Equity Incentive Plan

Share Options

The fair value of Equity Incentive Plan share options are estimated on the date of grant using the Black-Scholes option pricing model. The Company lacks significant company-specific historical and implied volatility information. Therefore, it estimates its expected share volatility based on the historical volatility of a publicly traded set of peer companies. Due to the lack of historical exercise history, the expected term of the Company’s share options has been determined using the “simplified” method for awards. The risk-free interest rate is determined by reference to the U.S. Treasury yield curve in effect at the time of grant of the award for time periods approximately

Table of Contents

equal to the expected term of the award. Expected dividend yield is zero based on the fact that the Company has never paid cash dividends and does not expect to pay any cash dividends in the foreseeable future.

The following weighted-average assumptions were used to estimate the fair value of the Equity Incentive Plan share options issued during the three and nine months ended September 30, 2023 and the periods ended September 30, 2022:

Included in the table above are 45,611 PSOs that vested upon the Company raising external capital of $75 million or more. The milestone was considered outside of the Company’s control, and accordingly the vesting of the PSOs were not considered probable until the financing event occurs. During the nine months ended September 30, 2023, the 45,611 PSOs became vested and an immaterial amount of share-based compensation expense was recognized in relation to these PSOs.

Market-Based Share Options

On March 20, 2023, the Company granted 306,373 options to purchase Class A Ordinary Shares (“Market-Based Share Options”) to a certain Director of the Board. These awards will vest only to the extent that the 20-day volume weighted average trading price (“VWAP”) of the Class A Ordinary Shares is over $30 per Class A Ordinary Share at any time prior to the fifth anniversary of the grant date. These awards have an exercise price of $8.16 and become exercisable when vested and the market condition is satisfied. These awards expire 10 years from the date of grant. The fair value of these Market-Based Share Options were estimated using a Monte Carlo valuation method.

Table of Contents

The following table sets forth the weighted-average assumptions used at the grant date to determine the fair value of the Company’s market-based PSOs granted during the nine months ended September 30, 2023. No Market-Based Share Options were granted during the three months ended September 30, 2023:

The expense recognized related to Market-Based Share Options during the three and nine months ended September 30, 2023 was approximately $0.2 million and $0.4 million, respectively.

Restricted Share Units

The Company issued RSUs to certain employees, executives, and directors pursuant to the Equity Incentive Plan. The fair value has been estimated based on the closing price of the stock on the grant date.

The expense recognized related to RSUs during the three and nine months ended September 30, 2023 was approximately $1.0 million and $1.4 million, respectively.

Equity Award Modification

On April 7, 2023, the Company and its President and Chief Operating Officer (the “COO”) entered into an agreement regarding the COO’s departure from the Company (the “Severance Agreement”). In connection with Severance Agreement, 59,594 of the share options previously granted to the COO became fully vested and exercisable, with any shares purchased under the option subject to an 18-month lockup period. The Company recognized approximately $0.6 million of incremental share-based compensation during the nine months ended September 30, 2023 related to this share option modification.

Other Share-based Compensation

In accordance with the anti-dilution provisions of the Pfizer Agreement, Pfizer was issued additional Series A-1 convertible preferred shares upon the closing of the Business Combination that were immediately converted to 267,939 Class A Ordinary Shares. During the three and nine months ended September 30, 2023, the Company recognized expense in the amount of $-0- and $2.2 million, respectively, related to these Class A Ordinary Shares based on their grant-date fair value.

As of September 30, 2023, there was approximately $20.4 million of total unrecognized share-based compensation expense related to options granted to employees, executives, and directors under the Company’s equity plans that is expected to be recognized over a weighted average period of 1.8 years. As of September 30, 2023, there was approximately $13.1 million of total unrecognized share-based compensation expense related to RSUs granted to certain employees, executives, and directors under the Company’s Equity Incentive Plan that is expected to be recognized over a weighted average period of 1.9 years.

Note Payable

On December 8, 2022, the Company received $7.6 million in net proceeds from the issuance of a promissory note (the “Note”) issued to Hydra, LLC (“Hydra”) with a face amount of $8.0 million. The Note accrues interest at 9% per annum. The maturity date of the Note is the earlier of (i) twelve months from the date of the Note or (ii) five business dates after the date on which the Company consummates the Business Combination. The proceeds from the Note were used to acquire the 2022 Lilly License. If the registration statement on Form S-4 relating to the Business Combination had not been declared effective by the SEC by February 15, 2023, or if the Business Combination was not consummated by March 31, 2023, Hydra had the right to accelerate the Note and receive an amount equal to 120% of the face amount of the Note, plus accrued interest. On March 8, 2023, the Company signed a limited waiver letter under the Note, pursuant to which Hydra agreed to waive its acceleration right in consideration of the Company paying to Hydra 125% of the principal amount (equal to $10.0 million in the aggregate). The Note was repaid on March 20, 2023, upon the consummation of the Business Combination.

The Company elected to account for the Note at fair value (Note 4). The Company recorded any changes in the fair value of the Note during the period through other expense in the condensed consolidated statement of operations.

Redeemable Noncontrolling Interest

As a finder’s fee for the 2022 Lilly License, the Company’s consolidated subsidiary Z33 issued 4,900,222 shares of Z33 Series Seed Preferred Shares to Stone Peach. Zura has the right, but not the obligation to purchase up to 50% of the Series Seed Preferred Shares issued to Stone Peach at a price per share of $2.448869 for a period of two years from the date of the agreement. Stone Peach has the right, but not the obligation to sell up to 50% of the Series Seed Preferred Shares issued to Stone Peach to Zura for a price per share of $2.040724 (the “Put Option”). Stone Peach may exercise its option at any time between the first anniversary and the second anniversary of the transaction. As it is not possible to specifically identify the shares that may be redeemed by exercising the Put Option, and the applicable unit of account is each share, the Company assessed that each share must be considered redeemable until the exercise or the expiration of the Put Option. Accordingly, the Z33 Series Seed Preferred Shares issued to Stone Peach represents redeemable noncontrolling interest.

Table of Contents

In April 2023, the Company agreed to, within six months of April 24, 2023, exercise its call option on 50% of the Z33 Series Seed Preferred Shares previously issued to Stone Peach. The Company agreed to settle its call option by issuing 2,000,000 Class A Ordinary Shares. The amended settlement terms represented an extinguishment and reissuance of the Z33 Series Seed Preferred Shares. The $10.9 million difference between the estimated fair value of the new instrument issued and the carrying value of the Z33 Series Seed Preferred Shares was recorded as a deemed dividend to the redeemable noncontrolling interest and as an adjustment to net loss to arrive at net loss attributable to Class A ordinary shareholders on the condensed consolidated statement of operations. The Company and Stone Peach are renegotiating the terms of the exercise of the call option.

As of September 30, 2023 and December 31, 2022, the redeemable noncontrolling interest balance was $20.9 million and $10.0 million, respectively.

Overview

Zura Bio Limited, formerly known as JATT Acquisition Corp., is a is a multi-asset clinical-stage biotechnology company focused on developing novel medicines for immune and inflammatory disorders. The experienced leadership team aims to become a leader in the autoimmunology field.

We were incorporated as a Cayman Islands exempted company on March 10, 2021. Our wholly owned subsidiary, Zura Bio Limited (“Zura Bio UK”) was formed in the United Kingdom, or UK, on January 18, 2022. Prior to March 20, 2023, our operations were conducted through Zura Bio UK.

We have a limited operating history. Since our inception, our operations have focused on organizing and staffing our company, business planning, raising capital and entering into collaboration agreements for conducting manufacturing, research and development activities. Our lead product candidates are in the clinical testing stage, however, we have not conducted any clinical tests ourselves, nor have any been conducted during the period since our inception. We do not have any product candidates approved for sale and have not generated any revenue from product sales. We have funded our operations through (i) the sale of equity, raising an aggregate of $10.0 million of gross proceeds from the sale of shares of convertible preferred stock of Zura Bio UK through March 31, 2023; (ii) the issuance of a promissory note, receiving net proceeds of $7.6 million in December 2022; (iii) proceeds from the Business Combination of $56.7 million in March 2023; and (iv) the April 2023 Private Placement, raising an aggregate of $80.0 million of gross proceeds from the sale of Class A Ordinary Shares and Pre-Funded Warrants during the nine months ended September 30, 2023.

Since our inception, we have incurred significant operating losses. Our net loss for the three and nine months ended September 30, 2023 was $8.3 million and $51.9 million, respectively. As of September 30, 2023, we had an accumulated deficit of $95.0 million. We anticipate that our expenses will increase significantly in connection with our ongoing activities, as we:

●

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

●

conduct our planned clinical and preclinical trials of ZB-168, ZB-106, and torudokimab, as well as initiate and complete additional trials of future potential product candidates;

●

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

●

scale up our clinical and regulatory capabilities;

●

manufacture current good manufacturing practices, or cGMP, material for clinical trials or potential commercial sales;

●

establish and validate a commercial-scale cGMP manufacturing facility, or use a contract manufacturing organization;

●

Concurrently with the April 2023 Private Placement, the Company agreed to, within six months of April 24, 2023, exercise its call option on 50% of the Z33 Series Seed Preferred Shares previously issued to Stone Peach. The Company agreed to settle its call option by issuing 2,000,000 Class A Ordinary Shares. The amended settlement terms represented an extinguishment and reissuance of the Z33 Series Seed Preferred Shares. The $10.9 million difference between the estimated fair value of the new instrument issued and the carrying value of the Z33 Series Seed Preferred Shares was recorded as a deemed dividend to the redeemable noncontrolling interest. The Company and Stone Peach are renegotiating the terms of the exercise of the call option.

2023 Lilly License

On April 26, 2023, the Company’s newly-formed subsidiary ZB17 LLC (“ZB17”) entered into a license agreement (the “2023 Lilly License” and, together with the 2022 Lilly License, the “Lilly Licenses”) with Lilly, for an exclusive license to develop, manufacture and commercialize a certain bispecific antibody relating to IL-17 and BAFF (“ZB-106”) in exchange for an upfront payment consisting of $5.8 million as well as 1,000,000 Class A Ordinary Shares issued at a fair value of $7.84 per Class A Ordinary Share. In addition, ZB17 will make a payment of $5.0 million upon the receipt of certain know-how, data, information and materials that Lilly is required to provide under the license agreement.

Table of Contents

In addition to the consideration transferred during the nine months ended September 30, 2023, the Company is obligated to make 4 development milestone payments to Lilly up to an aggregate of $155.0 million, and sales milestone payments up to an aggregate of $440 million based on respective thresholds of net sales of products developed from ZB-106. The Company is also obligated to pay Lilly over a multi-year period (twelve years, or upon the later expiration of regulatory exclusivity of ZB-106 in a country) an annual earned royalty at a marginal royalty rate in the mid-single digits to low-double digits, with increasing rates depending on net sales in the respective calendar year, based on a percentage of sales within varying thresholds for a certain period of years. The Company is obligated to pay BAFFX17 a fee equal to 3% of any milestone or royalty payments due to Lilly pursuant to the terms of either the 2022 Lilly License and the 2023 Lilly License with Lilly. Upon receiving written approval from the FDA, EMA, or similar regulatory authority of the Investigational New Drug (“IND”) and commencement and the commencement of a clinical trial in the applicable jurisdiction for ZB-106, Stone Peach will also receive a one-time payment of $4.5 million. Stone Peach will also receive a one-time milestone payment of $25 million upon either (i) certain equity-related transactions, or (ii) the receipt of regulatory approval from the applicable regulatory authority for any new indication in the applicable jurisdiction. Furthermore, Stone Peach was granted a royalty of 2% of the aggregate net sales of any products developed from the Compound.

Mr. Thiara has no family relationships with any of the executive officers or directors of the Company. There have been no transactions in the past two years to which the Company or any of its subsidiaries was or is to be a party, in which Mr. Thiara had, or will have, a direct or indirect material interest.

Components of Operating Results

Operating Expenses

General and Administrative Expenses

General and administrative expenses primarily consist of professional fees for legal, accounting, and consulting costs relating to corporate matters, as well as salaries and related costs for personnel in executive and administrative functions, including share-based compensation.

We anticipate that our general and administrative expenses will increase in the future as we continue to support research and development activities and incur increased costs of operating as a public company. These costs include increased headcount to support expanded operations and infrastructure.

Additionally, we anticipate increased costs associated with maintaining compliance with Nasdaq rules and SEC requirements such as accounting, audit, legal and consulting services, as well as director and officer liability insurance, investor and public relations activities.

Research and Development Expenses

Research and development (“R&D”) expenses consist primarily of consulting fees for medical and manufacturing advisory services and costs related to manufacturing material for preclinical studies. Expenses are recognized as the related goods are delivered or the services are performed.

R&D expenses include the cost of in-process research and development (“IPR&D”) assets purchased in an asset acquisition transaction. IPR&D assets are expensed unless the assets acquired are deemed to have an alternative future use, provided that the acquired asset did not also include processes or activities that would constitute a “business” as defined under U.S. GAAP, the drug has not achieved regulatory approval for marketing and, absent obtaining such approval, has no established alternative future use. Acquired IPR&D payments are immediately expensed in the period in which they are incurred and include upfront payments, as well as transaction fees and subsequent pre-commercial milestone payments. Research and development costs incurred after the acquisition are expensed as incurred. R&D expenses also include the remeasurement of the research and development license consideration liability.

Table of Contents

Research and development expenses could include:

●

employee-related expenses, including salaries, bonuses, benefits, share-based compensation and other related costs for those employees involved in research and development efforts;

●

external research and development expenses incurred under agreements with clinical research organizations, investigative sites and consultants to conduct our preclinical studies;

●

costs related to manufacturing material for preclinical studies and clinical trials, including fees paid to contract manufacturing organizations;

●

laboratory supplies and research materials;

●

costs related to compliance with regulatory requirements; and

●

facilities, depreciation and other allocated expenses, which include direct and allocated expenses for rent, maintenance of facilities, insurance and equipment.

Research and development activities are central to our business model. Product candidates in later stages of clinical development 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. We plan to substantially increase our research and development expenses for the foreseeable future as we develop our product candidates and manufacturing processes and conduct discovery and research activities for our preclinical and clinical programs. We cannot determine with certainty the timing of initiation, the duration or the completion costs of current or future preclinical studies and clinical trials of our product candidates due to the inherently unpredictable nature of preclinical and clinical development. Clinical and preclinical development timelines, the probability of success and development costs can differ materially from expectations. We anticipate that we will make determinations as to how we pursue our product candidates and how much funding to direct to each program on an ongoing basis in response to the results of future preclinical studies and clinical trials, regulatory developments and our ongoing assessments as to commercial potential. We will need to raise substantial additional capital in the future. Our clinical development costs are expected to increase as we commence, continue and expand our clinical trials. Our future expenses may vary significantly each period based on factors such as:

●

expenses incurred to conduct preclinical studies required to advance our product candidates into clinical trials;

●

per patient clinical trial costs, including based on the number of doses that patients receive;

●

the number of patients who enroll in each clinical trial;

●

the number of clinical trials required for approval;

●

the number of sites included in the clinical trials;

●

the countries in which the clinical trials are conducted;

●

the length of time required to enroll eligible patients;

●

the drop-out or discontinuation rates of patients;

●

potential additional safety monitoring requested by regulatory agencies;

●

the duration of patient participation in clinical trials and follow-up;

●

the phase of development of the product candidate;

●

third party contractors failing to comply with regulatory requirements or meet their contractual obligations in a timely manner, or at all;

Table of Contents

●

the cost of insurance, including product liability insurance, in connection with clinical trials;

●

regulators or institutional review boards requiring that we or our investigators suspend or terminate clinical development for various reasons, including noncompliance with regulatory requirements or a finding that the participants are being exposed to unacceptable health risks; and

●

the efficacy and safety profile of our product candidates

Operating Expenses

Research and Development Expenses

Research and development expenses increased by $29.1 million for the nine months ended September 30, 2023 compared to the period ended September 30, 2022. This was primarily due to an increase of $19.7 million of costs incurred to acquire licenses, as we recognized $7.5 million of expense related to the acquisition of an in-process research and development (“IPR&D”) license from Pfizer during the period months ended September 30, 2022 and $27.2 million in license and milestone fees related to the acquisition of an IPR&D license from Lilly during the nine months ended September 30, 2023. The increase was also due to the issuance of additional shares to Pfizer under an anti-dilution provision of $2.2 million recognized during the nine months ended September 30, 2023, an increase of $1.9 million related to the change in fair value of our research and development license consideration liability, and an increase of $4.3 million of costs to manufacture products for use in clinical studies, and an increase of $1.0 million of clinical and regulatory consulting services.

General and Administrative Expenses

General and administrative expenses increased by $12.9 million for the nine months ended September 30, 2023 compared to the period ended September 30, 2022.

professional fees for legal and accounting costs incurred related to our ongoing operations as a public company, an increase of $1.4 million of travel and office expenses.

Other Expense (Income)

Other expense, net

Other expense decreased by an immaterial amount for the three months ended September 30, 2023 compared to the three months ended September 30, 2022. This decrease was primarily due to a decrease in foreign exchange transaction loss.

Interest income

Interest income increased by $0.8 million for the nine months ended September 30, 2023 compared to the period ended September 30, 2022. This increase is due to an increase in our cash balance during the nine months ended September 30, 2023 compared to the period ended September 30, 2022.

Dividend income

Dividend income increased by $1.4 million for the nine months ended September 30, 2023 compared to the period ended September 30, 2022. The Company held no dividend-generating cash equivalents during the period ended September 30, 2022.

The redeemable noncontrolling interest was not outstanding during the period ended September 30, 2022.

Liquidity and Capital Resources

Overview

Since our inception, we have not generated any revenue and expect to continue to incur significant operating losses for the foreseeable future and may never become profitable. As of September 30, 2023, we had cash and cash equivalents of $103.9 million. As of September 30, 2023, we have funded our operations through (i) the sale of equity, raising an aggregate of $10.0 million of gross proceeds from the sale of our convertible preferred shares; (ii) the issuance of a promissory note, receiving net proceeds of $7.6 million;

Table of Contents

(iii) proceeds from the Business Combination of $56.7 million in March 2023; and (iv) the April 2023 Private Placement, raising an aggregate of $80.0 million of gross proceeds from the sale of Class A Ordinary Shares and Pre-Funded Warrants in May and June 2023.

We have experienced operating losses and cash outflows from operations since inception and will require ongoing financing in order to continue our research and development activities. We have not earned any revenue or reached successful commercialization of our products. Our future operations are dependent upon our ability to finance our cash requirements which will allow us to continue our research and development activities and the commercialization of our products. There can be no assurance that we will be successful in continuing to finance our operations.

Capital Requirements

To date, we have not generated revenue from any source, including the commercial sale of approved drug products, and we do not expect to generate revenue for at least the next few years. If we fail to complete the development of our product candidates in a timely manner or fail to obtain their regulatory approval, our ability to generate future revenue will be adversely affected. We do not know when, or if, we will generate any revenue from our product candidates, and we do not expect to generate revenue unless and until we obtain regulatory approval of, and commercialize, our product candidates.

We expect our expenses to increase significantly in connection with our ongoing activities, particularly as we continue the research and development, and seek marketing approval for our product candidates, as well as administrative costs associated with supporting our operations. In addition, if we obtain approval for any of our product candidates, we expect to incur significant commercialization expenses related to sales, marketing, manufacturing and distribution. Furthermore, we expect to incur additional costs associated with operating as a public company.

We will also be responsible to Pfizer and Lilly for significant future contingent payments under the Pfizer Agreement, the 2022 Lilly License, and the 2023 Lilly License (collectively with the 2022 Lilly License, the “Lilly Licenses”) upon the achievement of certain development, regulatory, and sales milestones, as well as ongoing royalties on net commercial sales. The size and timing of these milestone payments will vary greatly depending upon a number of factors, and it is therefore difficult to estimate the total payments that could become payable to Pfizer and Lilly and when those payments would be due. If we achieve all of the milestones, we would be obligated to pay multimillion dollar development and regulatory milestone payments and sales milestone payments. We will be required to pay certain of these milestone payments prior to the time at which we are able to generate sufficient revenue, if any, from commercial sales of any of our product candidates. We intend to fund these milestone payments using a portion of the proceeds from the Business Combination and the April 2023 Private Placement. In addition to milestone payments, we are also required to pay Pfizer and Lilly under the Pfizer Agreement and Lilly Licenses, respectively, ongoing royalties in the mid-single digits to low double-digits (less than 20%) percentage range based upon thresholds of net sales of products.

We anticipate that we will need substantial additional funding in connection with our continuing operations. We intend to devote most of the net proceeds from the Business Combination and the April 2023 Private Placement to the preclinical and clinical development of our product candidates, our public company compliance costs and certain milestone payments under the Pfizer Agreement and Lilly Licenses. Based on our current business plans, we believe that the net proceeds from the Business Combination and the Private Placement (as defined below) will enable us to fund our operating expenses and capital requirements through at least the next twelve months. Our estimate as to how long we expect the net proceeds from the Business Combination and the Private Placement to be able to fund our operating expenses and capital requirements is based on assumptions that may prove to be wrong, and we could use our available capital resources sooner than we currently expect. Changing circumstances, some of which may be beyond our control, could result in less cash available to us or cause us to consume capital significantly faster than we currently anticipate, and we may need to seek additional funds sooner than planned.

Because of the numerous risks and uncertainties associated with research, development and commercialization of pharmaceutical drug products, we are unable to estimate the exact amount of our operating capital requirements. Our future funding requirements will depend on many factors, including, but not limited to:

●

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

●

the costs and timing of process development and manufacturing scale-up activities associated with our product candidates and other programs as we advance them through preclinical and clinical development;

●

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

●

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

●

the timing and amount of our milestone payments to Pfizer under the Pfizer Agreement and to Lilly under the Lilly Licenses;

●

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

●

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

●

royalty payments to Pfizer under the Pfizer Agreement and Lilly under the Lilly Licenses;

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

●

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

●

the costs of operating as a public company

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 we may never generate the necessary data or results required to obtain marketing approval and achieve product sales. In addition, our product candidates, if approved, may not achieve commercial success. Our commercial revenues, if any, will be derived from sales of our product candidates that we do not expect to be commercially available in the near term, if at all. Accordingly, we will need to continue to rely on additional financing to achieve our business objectives. Adequate additional financing may not be available to us on acceptable terms, or at all. To the extent that we raise additional capital through the sale of equity or convertible debt securities, the terms of these equity securities or this debt may restrict our ability to operate. Any future debt financing and equity financing, if available, may involve covenants limiting and restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures, entering into profit-sharing or other arrangements or declaring dividends. If we raise additional funds through collaborations, strategic alliances or marketing, distribution or licensing arrangements with third parties, we may be required to relinquish valuable rights to our technologies, future revenue streams, research programs or product candidates or to grant licenses on terms that may not be favorable to us. If we are unable to raise capital when needed or on acceptable terms, we could be forced to delay, reduce or eliminate our research and development programs or future commercialization efforts.

Contractual Obligations and Other Commitments

We have or will enter into agreements in the normal course of business with contract research organizations, contract manufacturing organizations and other vendors for research and development services for operating purposes, which are generally cancelable upon written notice. Some third party CMOs have intellectual property, such as patents and/or know-how with an annual fee and royalty bearing license to its customers that forms part of the manufacturing agreement.

Lonza

We have entered into the Lonza License for a worldwide non-exclusive license for Lonza’s gene expression system in exchange for varying considerations depending on a number of factors such as whether the Company enters further into manufacturing agreements with Lonza or with a third party, and whether the Company enters into sublicense agreements with third parties (including up to middle six-figure annual payments per sublicense upon commencement of a sublicense, as well as royalties of up to low-single digit percentages of net sales of certain products over a commercially standard double-digit multi-year term). The Lonza License will remain in effect until terminated. The Company is free to terminate the Lonza License at any time upon 60 days’ notice, with or without cause. Lonza may terminate the Lonza License for cause upon a breach by the Company or for other commercially standard reasons.

WuXi Biologics

In July 2023, we entered into a biologics master services agreement (the “WuXi Biologics MSA”) with WuXi Biologics. Under the WuXi Biologics MSA, we are obligated to pay WuXi Biologics a service fee and all non-cancellable obligations in the amount specified in each work order associated with the agreement for the provision of services.

The WuXi Biologics MSA terminates on the completion of services under all work orders executed by the parties, unless terminated earlier. The term of each work order terminates upon completion of the services under such work order, unless terminated earlier. We can terminate the WuXi Biologics MSA or any work order at any time upon 30 days’ prior written notice and immediately upon written notice if WuXi Biologics fails to obtain or maintain required material governmental licenses or approvals. Either party may terminate a work order at any time upon three months’ prior notice with reasonable cause, provided however that if WuXi Biologics terminates a

Table of Contents

work order in such manner, no termination or cancellation fees shall be paid by us and immediately for cause upon the other party’s material breach that remains uncured for 30 days after notice of such breach.

In July 2023, we entered into a cell line license agreement (the “Cell Line License Agreement”) with WuXi Biologics. The Cell Line License Agreement provides the Company with a non-exclusive, worldwide, sublicensable license to certain of WuXi Biologics’s know-how, cell line, and biological materials (the “WuXi Biologics Licensed Technology”) to manufacture, have manufactured, use, sell and import certain products produced through the use of the cell line licensed by WuXi Biologics under the Cell Line License Agreement (the “WuXi Biologics Licensed Products”). In consideration for the license, we agreed to pay WuXi Biologics a non-refundable license fee of $150,000. Additionally, if we manufacture all of our commercial supplies of bulk drug product with a manufacturer other than WuXi Biologics or its affiliates, we are required to make royalty payments to WuXi Biologics in an amount equal to a fraction of a single digit percentage of global net sales of WuXi Biologics Licensed Products manufactured by a third-party manufacturer (the “Royalty”). If we manufacture part of our commercial supplies of the WuXi Biologics Licensed Products with WuXi Biologics or its affiliates, then the Royalty will be reduced accordingly on a pro rata basis.

The Cell Line License Agreement will continue indefinitely unless terminated (i) by us upon three months’ prior written notice and its payment of all undisputed amounts due to WuXi Biologics through the effective date of termination, (ii) by WuXi Biologics for a material breach by us that remains uncured for 30 days after written notice, or (iii) by WuXi Biologics if we fail to make a payment and such failure continues for 30 days after receiving notice of such failure.

We have not included future milestone or royalty payments or other contractual payment obligations as the timing and amount of such obligations are unknown or uncertain and are contingent upon the initiation, continuation, and/or successful completion of future activities.

Critical Accounting Estimates

Management’s discussion and analysis of our financial condition and results of operations is based on our unaudited condensed consolidated financial statements, which have been prepared in accordance with U.S. Generally Accepted Accounting Principles. The preparation of these unaudited condensed consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the unaudited condensed consolidated financial statements, as well as the reported expenses incurred during the reporting periods. Our estimates are based on our historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions and any such differences may be material.

Recent Accounting Pronouncements

See Note 2 to our unaudited condensed consolidated financial statements located in “Part I – Financial Information, Item 1. Financial Statements” in this Quarterly Report on Form 10-Q for a description of recent accounting pronouncements applicable to our financial statements.

Emerging Growth Company and Smaller Reporting Company Status

In April 2012, the JOBS Act was enacted. Section 107 of the JOBS Act provides that an “emerging growth company” can take advantage of the extended transition period provided in Section 7(a)(2)(B) of the Securities Act for complying with new or revised accounting standards. Thus, an emerging growth company can delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. Upon closing of the Business Combination, remained an emerging growth company and may elect to extend the transition period for complying with new or revised accounting standards, which delays the adoption of these accounting standards until they would apply to private companies.

In addition, as an emerging growth company, we may take advantage of specified reduced disclosure and other requirements that are otherwise applicable generally to public companies. These provisions include:

●

being permitted to present only two years of audited financial statements in addition to any required unaudited interim financial statements, with correspondingly reduced disclosure in the section titled “Management’s Discussion and Analysis of Financial Condition and Results of Operations”;

Table of Contents

●

an exception from compliance with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002, as amended;

●

reduced disclosure about our executive compensation arrangements in our periodic reports, proxy statements and registrations statements;

●

exemptions from the requirements of holding non-binding advisory votes on executive compensation or golden parachute arrangements; and an exemption from compliance with the requirements of the Public Company Accounting Oversight Board regarding the communication of critical audit matters in the auditor’s report on financial statements.

We would cease to qualify as an emerging growth company on the date that is the earliest of: (i) December 31, 2026, (ii) the last day of the fiscal year in which we have more than $1.07 billion in total annual gross revenues, (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 our Class A Ordinary Shares that is held by non-affiliates exceeds $700.0 million as of the prior June 30th, or (iv) the date on which we have issued more than $1.0 billion of non-convertible debt over the prior three-year period. We may choose to take advantage of some but not all of these reduced reporting burdens. We have taken advantage of certain reduced reporting requirements in this Quarterly report on Form 10-Q. Accordingly, the information contained herein may be different than you might obtain from other public companies in which you hold equity interests.

We are also a “smaller reporting company” as defined under the Securities Act and Exchange Act. We may continue to be a smaller reporting company so long as either (i) the market value of Class A Ordinary Shares held by non-affiliates is less than $250 million or (ii) our annual revenue was less than $100 million during the most recently completed fiscal year and the market value of Class A Ordinary Shares held by non-affiliates is less than $700 million. If we are 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 have reduced disclosure obligations regarding executive compensation, and, similar to emerging growth companies, if we are a smaller reporting company under the requirements of (ii) above, we would not be required to obtain an attestation report on internal control over financial reporting issued by our independent registered public accounting firm.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

As a “smaller reporting company”, we are not required to provide the information otherwise required by this Item 3.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our reports filed or submitted under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the time period specified in the SEC’s rules and forms, and that such information is accumulated and communicated to management including our Chief Executive Officer, Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. As of September 30, 2023, our Chief Executive Officer and Chief Financial Officer carried out an evaluation with the participation of management of the effectiveness of our disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934. Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective at a reasonable assurance level as of September 30, 2023.

Changes in Internal Control over Financial Reporting

There was no change in our internal control over financial reporting identified in connection with the evaluation required by Rule 13a-15(d) and 15d-15(d) of the Securities Exchange Act of 1934 that occurred during the quarter ended September 30, 2023 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Table of Contents

Inherent Limitations on Effectiveness of Internal Controls

A control system, no matter how well designed and operated, can provide only reasonable and not absolute assurance of achieving the desired control objectives. In reaching a reasonable level of assurance, management necessarily was required to apply its judgment in evaluating the benefits of possible controls and procedures relative to their costs. In addition, the design of any system of controls is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions; over time, controls may become inadequate because of changes in conditions, or the degree of compliance with policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

PART II

Item 1. Legal Proceedings

From time to time, we may become involved in litigation or other legal proceedings arising in the ordinary course of our business. We are not currently a party to any material litigation or legal proceedings that, in the opinion of our management, are likely to have a material adverse effect on our business. Regardless of outcome, litigation can have an adverse impact on us because of defense and settlement costs, diversion of management resources, negative publicity, reputational harm and other factors.

Item 1A. Risk Factors.

As a smaller reporting company, we are not required to make disclosures under this Item in our Quarterly Report on Form 10-Q.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds.

The securities issued in connection with the PIPE Subscription Agreements and Forward Purchase Agreement have not been registered under the Securities Act, in reliance on the exemption from registration provided by Section 4(a)(2) of the Securities Act.

Item 3. Defaults upon Senior Securities

None.

Item 4. Mine Safety Disclosures.

Not applicable.

Item 5. Other Information.

We are reporting the following information in lieu of reporting on a Current Report on Form 8-K under Item 5.02 – Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

2023 Lilly License

The acquisition was accounted for as an asset acquisition as substantially all of the fair value of the assets acquired is concentrated in a group of similar identifiable IPR&D assets. On the acquisition date, the compound licensed had not yet received regulatory approval and the in-process research and development did not have an alternative use. Accordingly, the Company expensed the entire cost of the 2023 Lilly License as a component of research and development in the condensed consolidated statement of operations during the nine months ended September 30, 2023.

As of September 30, 2023 and December 31, 2022, the noncontrolling interest balance was $1.5 million and $-0-, respectively.
