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 $41.9 million and $32.1 million as of March 31, 2023 and December 31, 2022, respectively, and a net loss of $9.6 million and $7.8 million for the three months ended March 31, 2023 and the period ended March 31, 2022, respectively. The Company’s existing sources of liquidity as of March 31, 2023 includes $44.0 million in cash.

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. 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 over the next twelve months.

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 subsidiary, Z33 Bio, Inc. (“Z33”), are shown in the condensed consolidated financial statements as redeemable noncontrolling interest. 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 March 31, 2023 and the results of operations for the three months ended March 31, 2023 and the period ended March 31, 2022. The results of operations for the three months ended March 31, 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 and related public warrants and private placement warrants (collectively, the “Warrants”), 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 share-based consideration transferred for acquired assets, the fair value of contingent consideration, the fair value of public and 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 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. Classification of the public 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.

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 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:

​

​

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.

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.

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:

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.

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

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, 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, 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 liabilities measured at fair value on a recurring basis as of March 31, 2023 and December 31, 2022, and the fair value hierarchy of the valuation techniques utilized.

​

​

​

There were no transfers into or out of Level 1, Level 2, or Level 3 during the three months ended March 31, 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:

​

​

The Company recorded a loss on remeasurement of the Note of $2.2 million for the three months ended March 31, 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 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:

​

​

The Company recorded a loss on the remeasurement of the research and development license consideration liability of $1.9 million for the three months ended March 31, 2023 within research and development on the condensed consolidated statement of operations.

Table of Contents

Private Placement Warrants

As of March 31, 2023, the Company has private placement warrants (see Note 9). 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:

​

​

The Company recorded a gain from the change in fair value of the private placement warrants of $0.2 million for the three months ended March 31, 2023 within change in fair value of private placement warrants on the condensed consolidated statement of operations.

Accounts payable and accrued expenses is comprised of the following as of March 31, 2023 and December 31, 2022:

​

​

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.

15

Table of Contents

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 March 31, 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.

Lilly License

On December 8, 2022, the Company’s consolidated subsidiary, Z33 Bio Inc. (“Z33”), entered into a license agreement (the “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 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 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. See Note 12 for further information.

Table of Contents

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 March 31, 2023, none of the contingent payments were due.

Prior to the Business Combination, Legacy Zura was authorized to issue Class A Ordinary Shares and Series A-1 convertible preferred shares. The outstanding Class A 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 Class A 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.

Each share of Series A-1 convertible preferred shares 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 share of Series A-1 convertible preferred shares 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.

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 March 31, 2023, no preferred shares were issued and outstanding.

As the accounting acquirer, Zura Bio is deemed to have assumed 5,910,000 private placement warrants to purchase Class A 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 Warrants will expire five years after the completion of the Business Combination, or earlier upon redemption or liquidation.

As of March 31, 2023, no warrants have been exercised or redeemed.

Public Warrants

The public warrants become 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 are 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, 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.

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 Class A Ordinary Shares available for issuance under the Option Plans, of which 383,371 Class A 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. The maximum number of Class A Ordinary Shares that may be issued under the Equity Incentive Plan are equal to 4,029,898, with 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 March 31, 2023, no shares no 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 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 2023 Equity Incentive Plan share options issued during the three months ended March 31, 2023:

Included in the table above are 45,611 PSOs that vest upon the Company raising external capital of $75 million or more. The milestone is considered outside of the Company’s control, and accordingly the vesting of the PSOs is not considered probable until the financing event occurs. As of March 31, 2023, no share-based compensation expense has been recognized in relation to these PSOs.
