Periodic Reporting and Financial Information

Our Class A Ordinary Shares and Public Warrants are registered under the Exchange Act and as a result we have reporting obligations, including the requirement that we file annual, quarterly and current reports with the SEC. The public may read and copy any materials we file with the SEC at the SEC’s Public Reference Room at 100 E Street, NE, Washington, DC 20549. You may obtain information on the operation of the Public Reference Room by calling the SEC at 1-800-SEC-0330. The SEC maintains an Internet site that contains reports, proxy and information statements, and other information regarding issuers that file electronically with the SEC at: http://www.sec.gov. The contents of this website are not incorporated into this filing. Further, our references to the uniform resource locator (“URL”) for this website are intended to be inactive textual references only.

We will be required to report our evaluation of our internal control over financial reporting for the fiscal year ending December 31, 2022 as required by the Sarbanes-Oxley Act. Only in the event we are deemed to be a large accelerated filer or an accelerated filer will we be required to have our internal control procedures audited. A target company may not be in compliance with the provisions of the Sarbanes-Oxley Act regarding adequacy of their internal controls. The development of the internal controls of any such entity to achieve compliance with the Sarbanes-Oxley Act may increase the time and costs necessary to complete any such acquisition.

We are an “emerging growth company,” as defined in Section 2(a) of the Securities Act, as modified by the JOBS Act. As such, we are eligible to take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not “emerging growth companies” including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements, and exemptions from the requirements of holding a non-binding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved. If some investors find our securities less attractive as a result, there may be a less active trading market for our securities and the prices of our securities may be more volatile.

​

Table of Contents

In addition, Section 107 of the JOBS Act also 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. In other words, an “emerging growth company” can delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. We intend to take advantage of the benefits of this extended transition period.

We will remain an emerging growth company until the earlier of (1) the last day of the fiscal year (a) following the fifth anniversary of the IPO Closing Date, (b) in which we have total annual gross revenue of at least $1.07 billion, or (c) in which we are deemed to be a large accelerated filer, which means the market value of our Class A Ordinary shares that is held by non-affiliates exceeds $700 million as of the prior June 30th, and (2) the date on which we have issued more than $1.0 billion in non-convertible debt securities during the prior three-year period. References herein to “emerging growth company” shall have the meaning associated with it in the JOBS Act.

In addition, we received a reimbursement from the underwriter of $480,000 to cover for certain offering expenses. In addition, $0.35 per unit, or approximately $3.4 million in the aggregate (net of the reimbursement from the underwriter of $820,000 from the deferred commissions for business combination expenses) will be payable to the underwriter for deferred underwriting commissions. The deferred fee will become payable to the underwriter from the amounts held in the Trust Account solely in the event that that we complete a Business Combination, subject to the terms of the underwriting agreement. In connection with the consummation of the Over-Allotment on July 19, 2021, the underwriter was paid an additional fee of $360,000 and an additional amount of $630,000 is payable in deferred underwriting commissions.

Forward Purchase Agreements

On August 5, 2021, we entered into Forward Purchase Agreements with certain of our Anchor Investors, Athanor Master Fund LP (“AMF”) and with Athanor International Master Fund, LP (“AIF”) (collectively the “Forward Purchase Agreements”, and collectively, “AMF and AIF are “FPA Purchasers”).

Pursuant to the Forward Purchase Agreements, we were to issue and sell to the FPA Purchasers, and the FPA Purchasers were to purchase from us, an aggregate of 7,500,000 forward purchase shares, or “Forward Purchase Shares”, for a purchase price of $10.00 per Forward Purchase Share, or $75,000,000 in the aggregate. Each Forward Purchase Share will consist of one Class A ordinary share of the Company. The Class A ordinary shares would have the same terms as the Company’s publicly traded Class A ordinary shares but will be restricted securities and not be freely tradable until registered with the Securities and Exchange Commission (SEC”).

In January 2022, we amended the Forward Purchase Agreements (“Amended Forward Purchase Agreements”) to: (1) reduce the number of forward purchase shares from an aggregate of 7,500,000 to 3,000,000 and from a total $75,000,000 in the aggregate to $30,000,000 in the aggregate; and (2) to add a requirement for the FPA Purchasers to provide a binding redemption backstop (the “Redemption Backstop”) to purchase an additional $15 million of redeeming shareholders in the event that redemptions are greater than 90% in connection with a Business Combination (the “Excess Redemptions”); and (3) to add a requirement that at the time of entering into a binding agreement for the Business Combination, the Purchasers will directly provide the target merger company (Target”) with bridge financing of $30 million evidenced by a convertible promissory note (“Convertible Note”) which shall be convertible into the our Class A ordinary shares at the closing of the Business Combination.

On March 8, 2023, the Company and the FPA Purchasers entered into Amendment No. 2 to Forward Purchase Agreement and Related Agreements, pursuant to which, among other things, the FPA Purchasers agreed to purchase up to 1,500,000 shares of JATT’s Class A ordinary shares from the Company for an aggregate purchase price of up to $15,000,000 in the event that redemptions exceed certain thresholds. The agreement previously provided that such shares would be purchased from public stockholders. The FPA Purchasers will be issued an additional 2,500,000 Class A Shares upon the closing of the business combination previously announced between JATT and Zura in connection with the amendment.

For more information, the full text of the Amended Forward Purchase Agreements are included as Exhibit 10.1 to our Annual Report on Form 10-K for the period ended December 31, 2021, filed with the SEC on April 11, 2022, and our Current Report on 8-K dated March 10, 2023.

Critical Accounting Policies and Estimates before the Business Combination

This management’s discussion and analysis of our financial condition and results of operations is based on our consolidated financial statements, which have been prepared in accordance with U.S. GAAP. The preparation of these consolidated financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses and the disclosure of contingent assets and liabilities in our consolidated financial statements. On an ongoing basis, we evaluate our estimates and judgments, including those related to fair value of financial instruments and accrued expenses. We base our estimates on historical experience, known trends and events and various other factors that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. We have identified the following as our critical accounting policies:

​

Table of Contents

Derivative Financial Instruments

We do not use derivative instruments to hedge exposures to cash flow, market, or foreign currency risks. We evaluate all of our financial instruments, including issued share purchase warrants, to determine if such instruments are derivatives or contain features that qualify as embedded derivatives, in accordance with the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”) Topic 480 “Distinguishing Liabilities from Equity” (“ASC 480”) and FASB ASC Topic 815, “Derivatives and Hedging” (“ASC 815”). The classification of derivative instruments, including whether such instruments should be recorded as liabilities or as equity, is re-assessed at the end of each reporting period.

The warrants issued in connection with the Initial Public Offering (the “Public Warrants”) and the Private Placement Warrants are recognized as derivative liabilities in accordance with ASC 815. Accordingly, we recognize the warrant instruments as liabilities at fair value and adjust the instruments to fair value at each reporting period. The liabilities are subject to re-measurement at each balance sheet date until exercised, and any change in fair value is recognized in the Company’s consolidated statements of operations. The fair value of the Public Warrants and the Private Placement Warrants were initially measured at fair value using a Monte Carlo simulation and a Black Scholes option pricing model, respectively. The fair value of the Private Placement Warrants continues to be measured using a Black-Scholes option pricing model. The fair value of the Public Warrants were subsequently measured at their listed trading price since they began to be separately listed and traded beginning in September 2021. Derivative warrant liabilities are classified as non-current liabilities as their liquidation will not be reasonably expected to require the use of current assets or require the creation of current liabilities.

Net Income (Loss) Per Ordinary Share

We comply with accounting and disclosure requirements of FASB ASC Topic 260, “Earnings Per Share.” The Company has two classes of shares, which are referred to as Class A ordinary shares and Class B ordinary shares. Income and losses are shared pro rata between the two classes of shares. Net income (loss) per ordinary share is calculated by dividing the net income (loss) by the weighted average ordinary shares outstanding for the respective period.

The calculation of diluted net income per share does not consider the effect of the warrants issued in connection with the Initial Public Offering (including exercise of the over-allotment option) and the Private Placement to purchase an aggregate of 12,810,000 ordinary shares because their exercise is contingent upon future events. The number of weighted average Class B ordinary shares for calculating basic net income per ordinary share was reduced for the effect of an aggregate of 450,000 Class B ordinary shares that were subject to forfeiture if the over-allotment option was not exercised in full or part by the underwriters. Since the contingency was satisfied, the Company included these shares in the weighted average number as of the beginning of the period to determine the dilutive impact of these shares. Fair value adjustment associated with the redeemable Class A ordinary shares is excluded from earnings per share as the redemption value approximates fair value.

Class A Ordinary Shares Subject to Possible Redemption

We account for our Class A ordinary shares subject to possible redemption in accordance with the guidance in ASC 480. Class A ordinary shares subject to mandatory redemption (if any) is classified as liability instruments and are measured at fair value. Conditionally redeemable Class A ordinary shares (including Class A ordinary shares that features redemption rights that are either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within the Company’s control) are classified as temporary equity. At all other times, Class A ordinary shares is classified as shareholders’ equity. Our Class A ordinary shares feature certain redemption rights that are considered to be outside of our control and subject to the occurrence of uncertain future events. As of December 31, 2022 and 2021, 13,800,000 shares of Class A ordinary shares are subject to possible redemption and are presented at redemption value as temporary equity, outside of the shareholders’ equity section of our consolidated balance sheets.

The Company recognizes changes in redemption value immediately as they occur and adjusts the carrying value of the Class A ordinary shares subject to possible redemption to equal the redemption value at the end of each reporting period. Effective with the closing of the Initial Public Offering (including exercise of the over-allotment option), we recognized the fair value adjustment from initial book value to redemption amount, which resulted in charges against additional paid-in capital (to the extent available) and accumulated deficit.

Recent Accounting Pronouncements

In August 2020, the FASB issued ASU No. 2020-06, Debt-Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging-Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity (“ASU 2020-06”), which simplifies accounting for convertible instruments by removing major separation models required under current GAAP. The ASU also removes certain settlement conditions that are required for equity-linked contracts to qualify for the derivative scope exception, and it simplifies the diluted earnings per share calculation in certain areas. We adopted ASU 2020-06 on March 10, 2021 (inception). Adoption of the ASU did not impact our financial position, results of operations or cash flows.

On April 5, 2012, the JOBS Act was signed into law. The JOBS Act contains provisions that, among other things, relax certain reporting requirements for qualifying public companies. We will qualify as an “emerging growth company” and under the JOBS Act will be allowed to comply with new or revised accounting pronouncements based on the effective date for private (not publicly traded) companies. We are electing to delay the adoption of new or revised accounting standards, and as a result, we may not comply with new or revised accounting standards on the relevant dates on which adoption of such standards is required for non-emerging growth companies. As such, our financial statements may not be comparable to companies that comply with public company effective dates.

Additionally, we are in the process of evaluating the benefits of relying on the other reduced reporting requirements provided by the JOBS Act. Subject to certain conditions set forth in the JOBS Act, if, as an “emerging growth company,” we choose to rely on such exemptions we may not be required to, among other things, (i) provide an auditor’s attestation report on our system of internal controls over financial reporting pursuant to Section 404, (ii) provide all of the compensation disclosure that may be required of non-emerging growth public companies under the Dodd-Frank Wall Street Reform and Consumer Protection Act, (iii) comply with any requirement that may be adopted by the PCAOB regarding mandatory audit firm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements (auditor discussion and analysis) and (iv) disclose certain executive compensation related items such as the correlation between executive compensation and performance and comparisons of the CEO’s compensation to median employee compensation. These exemptions will apply for a period of five years following the completion of our Initial Public Offering or until we are no longer an “emerging growth company,” whichever is earlier.

(COSO) in Internal Control — Integrated Framework (2013). Based on our assessments and those criteria, management determined that our internal controls over financial reporting were not effective as of December 31, 2022, for the reasons described above in Disclosure Controls and Procedures.

This Annual Report on Form 10-K does not include an attestation report of internal controls from our independent registered public accounting firm due to our status as an emerging growth company under the JOBS Act.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act) during the most recent fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting except for the below.

Our Chief Executive Officer and Chief Financial Officer performed additional accounting and financial analyses and other post-closing procedures including consulting with subject matter experts related to the accounting for certain complex financial instruments. The Company’s management has expended, and will continue to expend, a substantial amount of effort and resources for the remediation and improvement of our internal control over financial reporting. While we have processes to properly identify and evaluate the appropriate accounting technical pronouncements and other literature for all significant or unusual transactions, we have expanded and will continue to improve these processes to ensure that the nuances of such transactions are effectively evaluated in the context of the increasingly complex accounting standards. The elements of our remediation plan can only be accomplished over time, and we can offer no assurance that these initiatives will ultimately have the intended effects.

Board Composition

The Company’s business and affairs will be organized under the direction of its board of directors. The board of directors of the Company will meet on a regular basis and additionally as required. In accordance with the terms of the Second Amended and Restated Memorandum and Articles of Association, which will be effective upon the consummation of the Business Combination, The Company’s board of directors may establish the authorized number of directors from time to time by resolution. The Company’s board of directors will consist of seven members upon the consummation of the Business Combination.

Director Independence

In connection with the consummation of the Business Combination, the Company board of directors will undertake a review of the independence of each director. Based on information provided by each director concerning his or her background, employment and affiliations, it is expected that the board of directors of the Company will determine that none of the directors, other than Dr. Someit Sidhu, has any relationships that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director and that each of Amit Munshi, Sandeep Kulkarni, Garry Neil, Steve Schoch, Jennifer Jarrett and Neil Graham is “independent” as that term is defined under the Nasdaq listing standards. In making these determinations, the JATT board of directors will consider the current and prior relationships that each non-employee director has with the management and principal shareholders of Zura and all other facts and circumstances the Company’s board of directors deems relevant in determining their independence, including the beneficial ownership of securities of Zura by each non-employee director and the transactions described in the section titled “Certain Relationships and Related Party Transactions.”

Board Leadership Structure

The Company’s board of directors is expected to be chaired by Amit Munshi, an independent director. In such role, Amit Munshi will have authority, among other things, to call and preside over board of directors meetings, to set meeting agendas, and to determine materials to be distributed to the board of directors. The Company’s board of directors believes that separating the positions of Chief Executive Officer (“CEO”) and Chairman of the Board is in the best interests of the Company. We believe that keeping the two positions separate helps to ensure proper board oversight over management’s decision-making and performance, protects the board’s independence, and enables both the CEO and the Chairman of the Board to exercise their respective roles without the appearance of any conflict of interests or responsibilities.

Amit Munshi, Sandeep Kulkarni, Garry Neil, Steve Schoch, Jennifer Jarrett and Neil Graham will serve as independent directors who provide active and effective oversight of the Company’s strategic decisions. As of the date of this filing, the Company’s board of directors has determined that the leadership structure of the Company’s board of directors will permit the board of directors to fulfill its duties effectively and efficiently and is appropriate given the size and scope of the Company and its financial condition.

Board Oversight of Risk

Upon the consummation of Business Combination, one of the key functions of Company’s board of directors will be to conduct informed oversight of Company’s risk management process. Company’s board of directors does not anticipate having a standing risk management committee, but rather anticipates administering this oversight function directly through Company’s board of directors as a whole, as well as through various standing committees of the board of directors that address risks inherent in their respective areas of

​

oversight. In particular, the board of directors will be responsible for monitoring and assessing strategic risk exposure and Company’s audit committee will have the responsibility to consider and discuss Company’s major financial risk exposures and the steps its management will take to monitor and control such exposures, including guidelines and policies to govern the process by which risk assessment and management is undertaken. The audit committee will also monitor compliance with legal and regulatory requirements. Company’s compensation committee will also assess and monitor whether Company’s compensation plans, policies and programs comply with applicable legal and regulatory requirements.

Board Committees

After the consummation of the Business Combination, the board will establish an audit committee, a compensation committee, and a nominating and governance committee. The Company’s board may establish other committees to facilitate the management of the post-Business Combination company’s business. The Company’s board and its committees will set schedules for meeting throughout the year and can also hold extraordinary general meetings and act by written resolution from time to time, as appropriate. The Company’s board will delegate various responsibilities and authority to its committees as generally described below. The committees will regularly report on their activities and actions to the full Company board. Each member of the audit committee of the Company board is expected to qualify as an independent director in accordance with Nasdaq listing standards. The compensation and nominating and governance committees will each have at least one independent director. Each committee of the Company board will have a written charter approved by the Company board. Upon the consummation of the Business Combination, copies of each charter will be posted on Company’s website once established. The inclusion of the post-Business Combination company’s website address in this proxy statement/prospectus does not include or incorporate by reference the information on the Company’s website into this proxy statement/prospectus. Members will serve on these committees until their resignation or until otherwise determined by the board.

Audit Committee

After the consummation of the Business Combination, the members of Company’s audit committee will be Amit Munshi, Jennifer Jarrett and Steve Schoch, each of whom can read and understand fundamental financial statements. Each of Amit Munshi, Jennifer Jarrett and Steve Schoch is independent under the rules and regulations of the SEC and Nasdaq listing standards applicable to audit committee members. Steve Schoch will be the chair of the audit committee. The JATT board has determined that Steve Schoch qualifies as an audit committee financial expert within the meaning of SEC regulations and meets the financial sophistication requirements of the Nasdaq. In arriving at these determinations, the JATT board has examined each audit committee member’s scope of experience and the nature of their employment.

The primary purpose of the audit committee will be to discharge the responsibilities of Company’s board of directors with respect to the corporate accounting and financial reporting processes, systems of internal control and financial statement audits, and to oversee the independent registered public accounting firm. Specific responsibilities of the audit committee will include:

The primary purpose of the compensation committee will be to discharge the responsibilities of the board of directors in overseeing the compensation policies, plans and programs and to review and determine the compensation to be paid to executive officers, directors and other senior management, as appropriate. Specific responsibilities of the compensation committee will include:

Nominating and Governance Committee

The nominating and corporate governance committee will consist of Garry Neil, Neil Graham and Sandeep Kulkarni. The chair of the nominating and corporate governance committee will be Garry Neil.

Code of Ethics

Upon the consummation of the Business Combination, the board will adopt a Code of Conduct. The Code of Conduct will apply to all of Company’s employees, officers, and directors, as well as all of Company’s contractors, consultants, suppliers, and agents in connection with their work for Company. Upon the consummation of the Business Combination, the full text of Company’s Code of Conduct will be posted on the post-Business Combination company’s website when established.

statement/prospectus, and you should not consider information contained on Company’s website to be part of this proxy statement/prospectus.

Related Party Policy

Upon the consummation of the Business Combination, the Company board of directors will adopt a written related person transactions policy that sets forth the Company’s policies and procedures regarding the identification, review, consideration and oversight of “related person transactions.” For purposes of the Company’s policy only, a “related person transaction” is a transaction, arrangement or relationship (or any series of similar transactions, arrangements or relationships) in which Company or any of its subsidiaries are participants involving an amount that exceeds $120,000, in which any “related person” has a material interest.

A related person is any executive officer, director, nominee to become a director or a holder of more than 5% of any class of the Company’s voting securities (including Company’s ordinary shares), including any of their immediate family members and affiliates, including entities owned or controlled by such persons.

Under the policy, the related person in question or, in the case of transactions with a holder of more than 5% of any class of Company’s voting securities, an officer with knowledge of a proposed transaction, must present information regarding the proposed related person transaction to Company’s audit committee (or, where review by Company’s audit committee would be inappropriate, to another independent body of Company’s board of directors) for review. To identify related person transactions in advance, Company will rely on information supplied by Company’s executive officers, directors and certain significant shareholders.

In considering related person transactions, Company’s audit committee will take into account the relevant available facts and circumstances, which may include, but are not limited to:

The Company’s audit committee will approve only those transactions that it determines are fair to the Company and in the Company’s best interests. All of the transactions described above were entered into prior to the adoption of such policy. Certain of the foregoing disclosures are summaries of certain provisions of our related party agreements, and are qualified in their entirety by reference to all of the provisions of such agreements. Because these descriptions are only summaries of the applicable agreements, they do not necessarily contain all of the information that you may find useful. Copies of certain of the agreements (or forms of the agreements) have been filed as exhibits to the registration statement of which this prospectus is a part, and are available electronically on the website of the SEC at www.sec.gov.

Compensation Committee Interlocks and Insider Participation

None of our officers currently serves, or in the past year has served, as a member of the Board or compensation committee of any entity that has one or more executive officers serving on our Board.

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Exchange Act requires our officers, directors and persons who beneficially own more than ten percent of our Ordinary shares to file reports of ownership and changes in ownership with the SEC. These reporting persons are also required to furnish us with copies of all Section 16(a) forms they file. Based solely upon a review of such Forms, we believe that during the year ended December 31, 2021 there were no delinquent filers.

Code of Ethics

We have adopted a Code of Ethics applicable to our directors, officers and employees.. You are able to review these documents by accessing our public filings at the SEC’s web site at www.sec.gov. In addition, a copy of the Code of Ethics will be provided without charge upon request from us. We intend to disclose any amendments to or waivers of certain provisions of our Code of Ethics in a Current Report on Form 8-K. See the section of this annual report entitled “Where You Can Find Additional Information.”

Limitation on Liability and Indemnification of Officers and Directors

Our amended and restated memorandum and articles of association provides that our officers and directors will be indemnified by us to the fullest extent authorized by Cayman Islands law, as it now exists or may in the future be amended. In addition, our amended and restated memorandum and articles of association will provide that our directors will not be personally liable for monetary damages to us or our shareholders for breaches of their fiduciary duty as directors, unless they violated their duty of loyalty to us or our shareholders, acted in bad faith, knowingly or intentionally violated the law, authorized unlawful payments of dividends, unlawful share purchases or unlawful redemptions, or derived an improper personal benefit from their actions as directors.

We have entered into agreements with our officers and directors to provide contractual indemnification in addition to the indemnification provided for in our amended and restated memorandum and articles of association. Our bylaws also permit us to secure insurance on behalf of any officer, director or employee for any liability arising out of his or her actions, regardless of whether Cayman Islands law would permit such indemnification. We will purchase a policy of directors’ and officers’ liability insurance that insures our officers and directors against the cost of defense, settlement or payment of a judgment in some circumstances and insures us against our obligations to indemnify our officers and directors. Except with respect to any public shares they may acquire in this offering or thereafter (in the event we do not consummate an initial business combination), our officers and directors have agreed to waive (and any other persons who may become an officer or director prior to the initial business combination will also be required to waive) any right, title, interest or claim of any kind in or to any monies in the trust account, and not to seek recourse against the trust account for any reason whatsoever, including with respect to such indemnification.

These provisions may discourage shareholders from bringing a lawsuit against our directors for breach of their fiduciary duty. These provisions also may have the effect of reducing the likelihood of derivative litigation against officers and directors, even though such an action, if successful, might otherwise benefit us and our shareholders. Furthermore, a shareholder’s investment may be adversely affected to the extent we pay the costs of settlement and damage awards against officers and directors pursuant to these indemnification provisions.

We believe that these provisions, the directors’ and officers’ liability insurance and the indemnity agreements are necessary to attract and retain talented and experienced officers and directors.

Equity

Restricted Stock Units: Pursuant to Mr. Munshi’s offer letter and subject to the shareholders approving the Equity Incentive Plan, Mr. Munshi will be granted, effective as of the Closing, a Restricted Stock Unit (“RSU”) inducement grant award agreement providing for 500,000 shares of the post-Business Combination company, which shall be eligible to vest equally over four (4) years as follows: twenty-five percent (25%) on each of the anniversaries of the grant thereafter so that the RSUs are fully vested on the fourth anniversary of the grant date.

Performance Shares: Also pursuant to Mr. Munshi’s offer letter and subject to shareholder approval of the Plan, Zura shall grant to Mr. Munshi, effective as of the Closing, a Performance Share inducement grant award agreement providing for options to purchase shares in the post-Business Combination company with a target value of no less than $2,500,000 (based on the grant date value of any such award) at an exercise price per share of the fair market value of such a share at the date of grant, which will become exercisable if the 20-day volume weighted average trading price (“VWAP”) of the ordinary shares is over $30 per share at any time prior to the fifth anniversary of the Closing and while Mr. Munshi remains Chairman of the Board of Directors. Any shares issued upon exercise of these options will be held subject to lock-up provisions on the same terms as those issued to Zura Bio Limited’s other current option holders on Closing (to the extent that such provisions remain in force).

Upon annual re-election as a director after the fourth anniversary of Closing, a further equity award in respect of ordinary shares will be granted, with the exercise price and other terms to be consistent with market norms and as approved by the Compensation Committee.

The equity grants of RSUs and Performance Shares are conditioned upon Mr. Munshi not acting in an executive management capacity for another company while service as Non-Employee Executive Chairman for Zura and New JATT. This restrictive covenant terminates in second quarter 2023 when the role transitions to Chairman of the Board or as otherwise agreed by Zura or New JATT, as applicable, and Mr. Munshi.

Capital Compensation: Zura’s offer also included a grant of options to Mr. Munshi in an amount which equals six percent (6%) of the capital raised (excluding existing commitments/insider capital, and subject to a minimum price) until the Closing. These options shall have an exercise price equivalent to a price of $10.00 per ordinary share in New JATT on an as-exchanged basis and be eligible to vest over four (4) years as follows: twenty-five percent (25%) on the first anniversary of the grant and monthly thereafter (2.083 percent for each month thereafter).

Upon Closing, outstanding options will be exchanged for options to acquire shares in New JATT on equivalent commercial terms in accordance with the Business Combination Agreement. Shares issued upon exercise of these options will be held subject to certain lock-up provisions on the same terms as those issued to the Zura’s other current optionholders upon Closing (to the extent they remain in force).

of the Founder Shares was determined by dividing the amount of cash contributed to the company by the aggregate number of Founder Shares issued. The number of Founder Shares issued was determined based on the expectation that such founder shares would represent 20% of the outstanding shares upon completion of the Business Combination.

The Initial Shareholders have agreed, subject to limited exceptions, including transfers to permitted transferees, not to transfer, assign or sell any of their founder shares until six months after the consummation of a business combination or earlier if, subsequent to a business combination, JATT consummates a liquidation, merger, share exchange or other similar transaction that results in all of the public shareholders having the right to exchange their JATT Class A Ordinary Shares for cash, securities or other property.

Private Placement Warrants

Our sponsor has, pursuant to a written agreement, purchased an aggregate of 5,910,000 private placement warrants for a purchase price of $1.00 per warrant in a private placement that occurred simultaneously with the closing of our IPO offering. As such, our sponsor’s interest in this transaction is valued at $5,910,000. Each private placement warrant entitles the holder thereof to purchase one share of our Class A ordinary shares at a price of $11.50 per share. The private placement warrants (including the Class A ordinary shares issuable upon exercise thereof) may not, subject to certain limited exceptions, be transferred, assigned or sold by the holder.

Administrative Services Agreement

Commencing on the closing of our IPO, we have paid our sponsor a total of $10,000 per month for office space, utilities and secretarial and administrative support. Upon completion of our initial business combination or our liquidation, we will cease paying these monthly fees. In addition, we may pay our sponsor or any of our existing officers or directors, or any entity with which they are affiliated, a finder’s fee, consulting fee or other compensation in connection with identifying, investigating and completing our initial business combination. These individuals will also be reimbursed for any out of pocket expenses incurred in connection with activities on our behalf, such as identifying potential target businesses and performing due diligence on suitable business combinations. Our audit committee will review on a quarterly basis all payments that were made to our sponsor, officers, directors or our or their affiliates and will determine which fees and expenses and the amount of expenses that will be reimbursed. There is no cap or ceiling on payments that may be made to our sponsor, officers, directors or any of their respective affiliates.

Registration Rights

Holders of the Founder Shares, Private Placement Warrants (and their underlying securities) and any Warrants issued upon conversion of working capital loans (and their underlying securities), if any, have registration rights pursuant to a registration rights agreement. The holders of a majority of these securities are entitled to make up to three demands; excluding short form demands, that we register such securities. In addition, the holders have certain “piggy-back” registration rights with respect to registration statements filed by us subsequent to the completion of a Business Combination and rights to require us to register for resale such securities pursuant to Rule 415 under the Securities Act. However, the registration rights agreement provides that we will not permit any registration statement filed under the Securities Act to become effective until termination of the applicable lock-up period. We will bear the expenses incurred in connection with the filing of any such registration statements.

Related Party Notes

Prior to the closing of the IPO offering, our sponsor agreed to loan us up to an aggregate of $200,000 to be used for a portion of the expenses of the IPO. These loans are non-interest bearing, unsecured and are due at the closing of the Business Combination. The loan was repaid upon the closing of the IPO offering out of the estimated $1,250,000 of offering proceeds that has been allocated to the payment of offering expenses (other than underwriting commissions) not held in the trust account. The value of our sponsor’s interest in this transaction corresponds to the principal amount outstanding under any such loan.

Working Capital Loans

In addition, in order to finance transaction costs in connection with an intended initial business combination, our sponsor or an affiliate of our sponsor or certain of our officers and directors may, but are not obligated to, loan us funds as may be required. If we complete an initial business combination, we would repay such loaned amounts. In the event that the initial business combination does not close, we may use a portion of the working capital held outside the trust account to repay such loaned amounts but no proceeds from our trust account would be used for such repayment. Up to $1,500,000 of such loans may be convertible into warrants at a price of $1.00 per warrant at the option of the lender. The warrants would be identical to the private placement warrants, including as to exercise price,

exercisability and exercise period. The Sponsor has agreed to loan JATT an aggregate of up to $300,000 in working capital loan to cover expenses related to the Business Combination pursuant to a promissory note, dated May 11, 2022 (the “Note”). This loan is non- interest bearing. At September 30, 2022, $300,000 was outstanding under the Note. Such Working Capital Loans may be repaid out of the proceeds of the trust account that holds a portion of the proceeds of the IPO and the concurrent sale of the Private Placement Warrants (the “Trust Account”) released to JATT or converted into Lender Warrants at a price of $1.00 per warrant, such warrants to be identical to the private placement warrants. We do not expect to seek loans from parties other than our sponsor or an affiliate of our sponsor as we do not believe third parties will be willing to loan such funds and provide a waiver against any and all rights to seek access to funds in our trust account.

After our initial business combination, members of our management team who remain with us may be paid consulting, management or other fees from the combined company with any and all amounts being fully disclosed to our shareholders, to the extent then known, in the proxy solicitation materials or tender offer documents, as applicable, furnished to our shareholders. It is unlikely the amount of such compensation will be known at the time of distribution of such proxy solicitation materials or tender offer documents, as applicable, as it will be up to the directors of the post-combination business to determine executive and director compensation.

Insider Letter Agreement and Amendment

Upon the closing of the JATT IPO, the Sponsor, members of JATT’s board of directors and certain other individuals (collectively, the “Insiders”) who hold the Founder Shares entered into a letter agreement with JATT, pursuant to which they have agreed to (i) waive their redemption rights with respect to their Founder Shares and public shares in connection with the completion of our initial business combination, (ii) waive their redemption rights with respect to their Founder Shares and public shares in connection with a shareholder vote to approve an amendment to our amended and restated memorandum and articles of association to (A) modify the substance or timing of our obligation to provide for the redemption of our public shares in connection with an initial business combination or to redeem 100% of our public shares if we do not complete our initial business combination by April 17, 2023 or (B) with respect to any other material provisions relating to shareholders’ rights or pre-initial business combination activity, (iii) waive their rights to liquidating distributions from the trust account with respect to their Founder Shares if we fail to complete our initial business combination by April 17, 2023, although they will be entitled to liquidating distributions from the trust account with respect to any public shares they hold if we fail to complete our initial business combination within the prescribed time frame and (iv) vote any Founder Shares held by them and any public shares purchased during or after the Business Combination (including in open market and privately-negotiated transactions) in favor of our initial business combination.

In connection with the execution of the Business Combination Agreement, the Insiders who hold JATT Founder Shares entered into an Amendment to the Insider Letter Agreement (the “Amended Insider Letter Agreement”), which provides, among other things, that certain Founder Shares shall be subject to certain time and share-performance-based vesting provisions described below. The Sponsor and the Insiders agreed that they shall not transfer any Founder Shares until the earlier of (A) six months after the completion of the initial business combination and (B) the date following the completion of an initial business combination on which JATT completes a liquidation, merger, share exchange, reorganization or other similar transaction that results in all of the public shareholders having the right to exchange their JATT Class A Ordinary Shares for cash, securities or other property. Notwithstanding the foregoing, if, subsequent to the Business Combination, the closing price of the JATT Class A Ordinary Shares equals or exceeds $12.00 per share (as adjusted for share splits, share capitalizations, reorganizations, recapitalizations and the like) for any 20 trading days within any 30- trading day period commencing at least 150 days after the Business Combination, the Founder Shares shall be released from the lock-up restrictions. The Amended Insider Letter Agreement also provides that neither the Sponsor nor the Insiders will redeem any JATT Class A Ordinary Shares owned by such persons in connection with the Business Combination.

Related Party Policy

JATT’s Code of Ethics requires it to avoid, wherever possible, all related party transactions that could result in actual or potential conflicts of interests, except under guidelines approved by the JATT board (or the audit committee). Related-party transactions are defined as transactions in which (1) the aggregate amount involved will or may be expected to exceed $120,000 in any calendar year, (2) it or any of its subsidiaries is a participant, and (3) any (a) executive officer, director or nominee for election as a director, (b) greater than 5% beneficial owner of JATT Class A Ordinary Shares, or (c) immediate family member, of the persons referred to in clauses (a) and (b), has or will have a direct or indirect material interest (other than solely as a result of being a director or a less than 10% beneficial owner of another entity). A conflict of interest situation can arise when a person takes actions or has interests that may make it difficult to perform his or her work objectively and effectively. Conflicts of interest may also arise if a person, or a member of his or her family, receives improper personal benefits as a result of his or her position.

​

Table of Contents

The audit committee, pursuant to its written charter, will be responsible for reviewing and approving related-party transactions to the extent JATT enters into such transactions. The audit committee will consider all relevant factors when determining whether to approve a related party transaction, including whether the related party transaction is on terms no less favorable to JATT than terms generally available from an unaffiliated third-party under the same or similar circumstances and the extent of the related party’s interest in the transaction. No director may participate in the approval of any transaction in which he is a related party, but that director is required to provide the audit committee with all material information concerning the transaction. JATT also requires each of its directors and executive officers to complete a directors’ and officers’ questionnaire that elicits information about related party transactions.

These procedures are intended to determine whether any such related party transaction impairs the independence of a director or presents a conflict of interest on the part of a director, employee or officer.

To further minimize conflicts of interest, JATT has agreed not to consummate an initial business combination with an entity that is affiliated with any of the Sponsor, officers or directors unless it has obtained an opinion from an independent investment banking firm, or another independent entity that commonly renders valuation opinions, and the approval of a majority of our disinterested independent directors that the Business Combination is fair to JATT’s unaffiliated shareholders from a financial point of view.

PIPE Financing Subscription Agreement

In connection with the execution of the Business Combination Agreement, JATT entered into the Subscription Agreement with an accredited investor, pursuant to which such investor agreed to purchase, in the aggregate, 2,000,000 New JATT Class A Ordinary Shares at $10.00 per share for an aggregate commitment amount of $20 million. The closing under the Subscription Agreement will occur substantially concurrently with the Closing.

The Subscription Agreement provides that, solely with respect to subscriptions by the PIPE Investor, New JATT is required to file with the SEC, within 30 days after the Closing (the “Filing Deadline”), a registration statement registering the resale of the New JATT Class A Ordinary Shares to be issued to any such third-party investor and to use its commercially reasonable efforts to have such registration statement declared effective as soon as practicable after the filing thereof but no later than the earlier of (i) the 90th calendar day (or 120th calendar day if the SEC reviews the and has written comments to such registration statement) following the earlier of (A) the filing of the registration statement and (B) Filing Deadline and (ii) the 10th business day after the date New JATT is notified (in writing) by the SEC that such registration statement will not be “reviewed” or will not be subject to further review. However, New JATT may delay such filing or effectiveness of such registration statement under certain circumstances, including if the Company were required to update the financial statements included in such registration statement in order to comply with Regulation S-X age of financial statement requirements.

Additionally, pursuant to the Subscription Agreement, the PIPE Investor agreed to waive any claims that it may have at the Closing or in the future as a result of, or arising out of, the Subscription Agreement against JATT, including with respect to the Trust Account. The Subscription Agreement will terminate, and be of no further force and effect, upon the earlier to occur of (i) such date and time as the Business Combination Agreement is terminated in accordance with its terms and (ii) upon the mutual written agreement of New JATT, JATT and the applicable PIPE Investor. Additionally, contingent upon the percentage of public shareholders who elect to redeem their shares at Closing, the PIPE Investor shall receive up to 1,654,800 Forfeited Private Placement Warrants transferred from the Sponsor.

Pursuant to the Business Combination Agreement, JATT may enter into subscription agreements with additional investors, providing for aggregate investments (including the PIPE Financing) in New JATT Class A Ordinary Shares in a private placement of an amount not less than $20,000,000 at $10 per New JATT Class A Ordinary Share.

Assuming the New JATT Class A Ordinary Shares would have a market value equivalent to that of the JATT public shares, the shares to be purchased in the PIPE Financing by the PIPE Investor would have an aggregate market value of approximately $20.9 million, based on the closing price of JATT public shares of $10.45 on the NYSE on February 16, 2023, the Record Date for the General Meeting.

Additionally, contingent upon the percentage of public shareholders who elect to redeem their shares at Closing, the PIPE Investor shall receive up to 1,654,800 Forfeited Private Placement Warrants transferred from the Sponsor.

Lilly Lock-Up Agreement

Pursuant to the JATT Equity Grant Agreement, Lilly agreed to enter into a Lock-up Agreement with JATT (the “Lilly Lock-Up Agreement”) to take effect at Closing, containing restrictions on transfer with respect to the shares issued to Lilly under the JATT Equity Grant Agreement (subject to certain exceptions, the “Lilly Lock-Up Shares”) for a period as follows: one-third (1/3) of the Lilly Lock-Up Shares will be restricted until 6 months after the Closing, one-third (1/3) of the Lilly Lock-Up Shares will be restricted until 12 months after the Closing, and one-third (1/3) of the Lilly Lock-Up Shares shall be restricted until 24 months after the Closing; provided, that each portion of the Lilly Lock-Up Shares will be freely tradable on the earlier of (i) the date on which the closing price of the JATT ordinary shares equals or exceeds $12.00 per share (as adjusted for share splits, share dividends, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period on a VWAP (as defined below) basis during the relevant lock-up period; and (ii) the date on which JATT consummates a liquidation, merger, capital share exchange, reorganization, or other similar transaction that results in all of JATT’s shareholders having the right to exchange their JATT ordinary shares for cash, securities or other property. For purposes of the Lilly Lock-Up Agreement, “VWAP” means, for any date, the daily volume weighted average price of the JATT ordinary shares for such date (or the nearest preceding date) on the trading market on which the JATT ordinary shares are then listed or quoted as reported by Bloomberg L.P. (based on a trading day from 9:30 a.m. (New York City time) to 4:00 p.m. (New York City time)).

Policy for Approval of Related Party Transactions

The audit committee of our board of directors will adopt a policy setting forth the policies and procedures for its review and approval or ratification of “related party transactions.” A “related party transaction” is any consummated or proposed transaction or series of transactions: (i) in which the company was or is to be a participant; (ii) the amount of which exceeds (or is reasonably expected to exceed) $120,000 in the aggregate over the duration of the transaction (without regard to profit or loss); and (iii) in which a “related party” had, has or will have a direct or indirect material interest. “Related parties” under this policy will include: (i) our directors, nominees for director or executive officers; (ii) any record or beneficial owner of more than 5% of any class of our voting securities; (iii) any immediate family member of any of the foregoing if the foregoing person is a natural person; and (iv) any other person who maybe a “related person” pursuant to Item 404 of Regulation S-K under the Exchange Act. Pursuant to the policy, the audit committee will consider (i) the relevant facts and circumstances of each related party transaction, including if the transaction is on terms comparable to those that could be obtained in arm’s-length dealings with an unrelated third party, (ii) the extent of the related party’s interest in the transaction, (iii) whether the transaction contravenes our code of ethics or other policies, (iv) whether the audit committee believes the relationship underlying the transaction to be in the best interests of the company and its shareholders and (v) the effect that the transaction may have on a director’s status as an independent member of the board and on his or her eligibility to serve on the board’s committees. Management will present to the audit committee each proposed related party transaction, including all relevant facts and circumstances relating thereto. Under the policy, we may consummate related party transactions only if our audit committee approves or ratifies the transaction in accordance with the guidelines set forth in the policy. The policy will not permit any director or executive officer to participate in the discussion of, or decision concerning, a related person transaction in which he or she is the related party.

ZURA BIO LTD

(Formerly JATT Acquisition Corp)

NOTE 1. DESCRIPTION OF ORGANIZATION, BUSINESS OPERATIONS AND BASIS OF PRESENTATION

​

Zura Bio Ltd., formerly known as JATT Acquisition Corp (the “Company”) was a blank check company incorporated as a Cayman Islands exempted company on March 10, 2021. The Company was incorporated for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses that the Company has not yet identified (“Business Combination”).

As of December 31, 2022, the Company had not yet commenced operations. All activity for the period from March 10, 2021 (inception) through December 31, 2022, relates to the Company’s formation and the initial public offering (the “Initial Public Offering”), which is described below, and since the Initial Public Offering the search for a Business Combination. The Company will not generate any operating revenues until after the completion of its initial Business Combination, at the earliest. The Company generates non-operating income in the form of interest income from the proceeds derived from the Initial Public Offering. The Company has selected December 31 as its fiscal year end.

The Company’s sponsor is JATT Ventures, L.P., a Cayman Islands exempted limited partnership (the “Sponsor”). The registration statement for the Company’s Initial Public Offering was declared effective on July 13, 2021. On July 16, 2021, the Company consummated its Initial Public Offering of 12,000,000 units (the “Units” and, with respect to the Class A ordinary shares included in the Units being offered, the “Public Shares”), at $10.00 per Unit, generating gross proceeds of $120.0 million, and incurring offering costs of approximately $10.5 million (net of reimbursement from underwriter of $480,000), of which approximately $3.4 million was for deferred underwriting commissions (see Note 5), approximately $4.7 million was incentives provided to Anchor Investors by the Sponsor (see Note 4), and approximately $685,000 of offering costs allocated to derivative warrant liabilities. On July 19, 2021, the underwriters fully exercised their option and purchased 1,800,000 additional Units, generating gross proceeds of $18.0 million (the “Over-Allotment”), and incurring offering costs of $990,000, of which $630,000 was for deferred underwriting commissions and approximately $62,000 was allocated to derivative warrant liabilities.

Simultaneously with the closing of the Initial Public Offering, the Company consummated the private placement (“Private Placement”) of 5,370,000 warrants (each, a “Private Placement Warrant” and collectively, the “Private Placement Warrants”), at a price of $1.00 per Private Placement Warrant to the Sponsor, generating proceeds of approximately $5.4 million (see Note 4). Concurrent with the consummation of the Over-Allotment on July 19, 2021, the Sponsor purchased 540,000 additional Private Placement Warrants, generating proceeds of $540,000 (the “Second Private Placement”).

Upon the closing of the Initial Public Offering and the Private Placement on July 16, 2021, and the Over-Allotment and Second Private Placement on July 16, 2021, approximately $139.4 million ($10.10 per Unit) of the net proceeds were placed in a trust account (“Trust Account”) with Continental Stock Transfer & Trust Company acting as trustee and invested in United States “government securities” within the meaning of Section 2(a)(16) of the Investment Company Act having a maturity of 185 days or less or in money market funds meeting certain conditions under Rule 2a-7 promulgated under Investment Company Act of 1940, as amended, (the “Investment Company Act”), which invest only in direct U.S. government treasury obligations, as determined by the Company, until the earlier of: (i) the completion of a Business Combination and (ii) the distribution of the Trust Account as described below.

The Company’s management has broad discretion with respect to the specific application of the net proceeds of its Initial Public Offering and the sale of Private Placement Warrants, although substantially all of the net proceeds are intended to be applied generally toward consummating a Business Combination. The Company’s initial Business Combination must be with one or more operating businesses or assets with a fair market value equal to at least 80% of the net assets held in the Trust Account (excluding any deferred underwriters fees and taxes payable on the income earned on the Trust Account) at the time the Company signs a definitive agreement in connection with the initial Business Combination. However, the Company will only complete a Business Combination if the post-transaction company owns or acquires 50% or more of the outstanding voting securities of the target or otherwise acquires a controlling interest in the target sufficient for it not to be required to register as an investment company under the Investment Company Act.

The Company will provide its holders of the Public Shares (the “Public Shareholders”) with the opportunity to redeem all or a portion of their Public Shares upon the completion of a Business Combination either (i) in connection with a general meeting called to approve the Business Combination or (ii) by means of a tender offer. The decision as to whether the Company will seek shareholder approval of a Business Combination or conduct a tender offer will be made by the Company, solely in its discretion. The Public Shareholders will be entitled to redeem their Public Shares for a pro rata portion of the amount then in the Trust Account (initially at $10.10 per share, plus any pro rata interest earned on the funds held in the Trust Account and not previously released to the Company to pay its tax obligations). The per-share amount to be distributed to Public Shareholders who redeem their Public Shares will not be reduced by the deferred underwriting commissions the Company will pay to the underwriters (as discussed in Note 5). These Public Shares have been recorded at a redemption value and classified as temporary equity in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 480 “Distinguishing Liabilities from Equity” (“ASC 480”). In such case, the Company will proceed with a Business Combination if the Company has net tangible assets of at least $5,000,001 upon such consummation of a Business Combination and a majority of the shares voted are voted in favor of the Business Combination. If a shareholder vote is not required by law and the Company does not decide to hold a shareholder vote for business or other legal reasons, the Company will, pursuant to the amended and restated memorandum and articles of association which were adopted by the Company upon the consummation of the Initial Public Offering (the “amended and restated memorandum and articles of association”), conduct the redemptions pursuant to the tender offer rules of the U.S. Securities and Exchange Commission (the “SEC”), and file tender offer documents with the SEC prior to completing a Business Combination. If, however, a shareholder approval of the transactions is required by law, or the Company decides to obtain shareholder approval for business or legal reasons, the Company will offer to redeem shares in conjunction with a proxy solicitation pursuant to the proxy rules and not pursuant to the tender offer rules. Additionally, each Public Shareholder may elect to redeem their Public Shares irrespective of whether they vote for or against the proposed transaction. If the Company seeks shareholder approval in connection with a Business Combination, the holders of the Founder Shares prior to this Initial Public Offering (the “Initial Shareholders”) have agreed to vote their Founder Shares (as defined in Note 4) and any Public Shares purchased during or after the Initial Public Offering in favor of a Business Combination. In addition, the Initial Shareholders agreed to waive their redemption rights with respect to their Founder Shares and Public Shares in connection with the completion of a Business Combination. In addition, the Company agreed not to enter into a definitive agreement regarding an initial Business Combination without the prior consent of the Sponsor.

Notwithstanding the foregoing, the Company’s amended and restated memorandum and articles of association provides that a Public Shareholder, together with any affiliate of such shareholder or any other person with whom such shareholder is acting in concert or as a “group” (as defined under Section 13 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), will be restricted from redeeming its shares with respect to more than an aggregate of 15% or more of the Class A ordinary shares sold in the Initial Public Offering, without the prior consent of the Company.

The Company’s Sponsor, officers and directors have agreed not to propose an amendment to the Company’s amended and restated memorandum and articles of association that would affect the substance or timing of the Company’s obligation to provide for the redemption of its Public Shares in connection with a Business Combination or to redeem 100% of its Public Shares if the Company does not complete a Business Combination, unless the Company provides the Public Shareholders with the opportunity to redeem their Class A ordinary shares in conjunction with any such amendment.

If the Company is unable to complete a Business Combination by April 17, 2023 (the “Combination Period”), the Company will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten business days thereafter, redeem the Public Shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account (less taxes payable and up to $100,000 of interest to pay dissolution expenses), divided by the number of then outstanding Public Shares, which redemption will completely extinguish Public Shareholder’s rights as shareholders (including the right to receive further liquidating distributions, if any) and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the remaining shareholders and the board of directors, liquidate and dissolve, subject, in the case of clauses (ii) and (iii), to the Company’s obligations under Cayman Islands law to provide for claims of creditors and in all cases subject to the other requirements of applicable law.

​

In connection with the redemption of 100% of the Company’s outstanding Public Shares for a portion of the funds held in the Trust Account, each holder will receive a full pro rata portion of the amount then in the Trust Account, plus any pro rata interest earned on the funds held in the Trust Account and not previously released to the Company to pay the Company’s taxes payable (less up to $100,000 of interest to pay dissolution expenses).

The Initial Shareholders agreed to waive their liquidation rights with respect to the Founder Shares if the Company fails to complete a Business Combination within the Combination Period. However, if the Initial Shareholders should acquire Public Shares in or after the Initial Public Offering, they will be entitled to liquidating distributions from the Trust Account with respect to such Public Shares if the Company fails to complete a Business Combination within the Combination Period. The underwriters agreed to waive their rights to their deferred underwriting commission (see Note 5) held in the Trust Account in the event the Company does not complete a Business Combination within in the Combination Period, and, in such event, such amounts will be included with the funds held in the Trust Account that will be available to fund the redemption of the Company’s Public Shares. In the event of such distribution, it is possible that the per share value of the residual assets remaining available for distribution (including Trust Account assets) will be only $10.10 per share initially held in the Trust Account. In order to protect the amounts held in the Trust Account, the Sponsor agreed that it will be liable to the Company if and to the extent any claims by a third party for services rendered or products sold to the Company, or a prospective target business with which the Company has entered into a written letter of intent, confidentiality or other similar agreement or business combination agreement, reduce the amount of funds in the Trust Account to below the lesser of (i) $10.10 per Public Share and (ii) the actual amount per Public Share held in the trust account as of the date of the liquidation of the Trust Account, if less than $10.10 per share due to reductions in the value of the trust assets, less taxes payable; provided that such liability will not apply to any claims by a third party or prospective target business who executed a waiver of any and all rights to the monies held in the Trust Account (whether or not such waiver is enforceable) nor will it apply to any claims under the Company’s indemnity of the underwriters of the Initial Public Offering against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”). In the event that an executed waiver is deemed to be unenforceable against a third party, the Sponsor will not be responsible to the extent of any liability for such third-party claims. The Company will seek to reduce the possibility that the Sponsor will have to indemnify the Trust Account due to claims of creditors by endeavoring to have vendors, service providers (except the Company’s independent registered public accounting firm), prospective target businesses or other entities with which the Company does business, execute agreements with the Company waiving any right, title, interest or claim of any kind in or to monies held in the Trust Account.

Trust Account Redemptions and Extension of Combination Period

On January 12, 2023, the Company held an extraordinary general shareholders meeting to vote upon a charter amendment to extend the time to complete a Business Combination until April 17, 2023 (the “Extension Amendment”). The shareholders approved the Extension Amendment. As a result of the approval of the Extension Amendment, the Sponsor (or one or more of its affiliates, members or third-party designees) has made a deposit into the Trust Account in the amount of $101,339, which was the lesser of (a) $200,000 or (b) $0.06 for each Public Share that was not redeemed in connection with the extraordinary general meeting, in exchange for an unsecured promissory note issued by the Company to the Sponsor. Also in connection with the Extension Amendment, holders of Public Shares elected to redeem 12,111,022 Class A ordinary shares, at a redemption price of $10.257 per share, for an aggregate redemption amount of approximately $124.2 million. Following such redemptions, approximately $17.4 million remains in the Trust Account, including the extension payment made by the Sponsor into the Trust Account of $101,339, and 1,688,978 Public Shares remain outstanding.

On March 20, 2023 (the “Closing Date”), Zura Bio Limited, a limited company incorporated under the laws of England and Wales (“Zura”), JATT Acquisition Corp, a Cayman Islands exempted company (“JATT”), JATT Merger Sub, a Cayman Islands exempted company and wholly owned subsidiary of JATT (“Merger Sub”), JATT Merger Sub 2, a Cayman Islands exempted company and wholly owned subsidiary of JATT (“Merger Sub 2”) and Zura Bio Holdings Ltd, a Cayman Islands exempted company (“Holdco”), consummated the closing of the transactions contemplated by the Business Combination Agreement, dated June 16, 2022, as amended on September 20, 2022, November 14, 2022 and January 13, 2023, by and among Zura, JATT, Merger Sub, Merger Sub 2, and Holdco

Hydra Promissory Note

On December 8, 2022, Zura and Hydra LLC, a Cayman Islands limited liability company managed and controlled by Verender S. Badial and Someit Sidhu (“Hydra”), entered into a promissory note (the “Hydra Promissory Note”) pursuant to which (i) Hydra loaned to Zura a principal amount (the “Principal Amount”) of $8 million (including an original issue discount of $400,000) with an interest rate equal to 9.0% per annum, compounding daily. Under the Hydra Promissory Note, Hydra had the right to accelerate the Hydra Promissory Note and receive an amount equal to 120% of the Principal Amount because the registration statement on Form S-4 relating to the Business Combination was not declared effective by the SEC on or before February 15, 2023. On March 8, 2023, Zura and Hydra signed a limited waiver letter under the Hydra Promissory Note (the “Waiver Letter”), pursuant to which Hydra agreed to waive its acceleration right in consideration of Zura paying to Hydra 125% of the Principal Amount (equal to $10,000,000 in the aggregate) on the earlier of December 8, 2023 and five business days after the consummation of the Business Combination. On March 21, 2023, Zura repaid the Hydra Promissory Note in full and the Hydra Promissory Note was terminated.

As of the Closing Date and following the completion of the Business Combination, the Company had the following outstanding securities (including derivative securities):

Liquidity and Capital Resources

The Company’s liquidity needs through December 31, 2021, were satisfied through the cash contribution of $25,000 from the Sponsor to purchase Founder Shares (as defined in Note 4), and a loan from its Sponsor of approximately $117,000 under the Note (as defined in Note 4). The Company repaid the Note in full on July 21, 2021. Subsequent to the consummation of the Initial Public Offering, the Company’s liquidity has been satisfied through the net proceeds from the consummation of the Initial Public Offering and the Private Placement held outside of the Trust Account. In addition, in order to finance transaction costs in connection with a Business Combination, the Sponsor or an affiliate of the Sponsor, or certain of the Company’s officers and directors may, but are not obligated to, provide the Company Working Capital Loans (as defined in Note 4). As of December 31, 2022 and 2021, there was approximately $356,000 and $0 outstanding under Working Capital Loans, respectively.

NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The accompanying consolidated financial statements are presented in U.S. dollars in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and pursuant to the rules and regulations of the SEC.

Emerging Growth Company

The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act, as modified by the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”), and it may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not

​

being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002, reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved.

Further, Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that an emerging growth company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. The Company has elected not to opt out of such extended transition period which means that when a standard is issued or revised and it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of the Company’s financial statement with another public company which is neither an emerging growth company nor an emerging growth company which has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used.

Principles of Consolidation

The accompanying consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries, Merger Sub and Merger Sub 2. All significant intercompany accounts and transactions have been eliminated in consolidation.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires 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 consolidated financial statements and the reported amounts of revenues and expenses during the reporting periods.

Making estimates requires management to exercise significant judgment. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the consolidated financial statements, which management considered in formulating its estimate, could change in the near term due to one or more future confirming events. Accordingly, the actual results could differ significantly from those estimates.

Cash and Cash Equivalents

The Company considers all short-term investments with an original maturity of three months or less when purchased to be cash equivalents. There were no cash equivalents at December 31, 2022 and 2021.

Concentration of Credit Risk

Financial instruments that potentially subject the Company to concentration of credit risk consist of a cash account in a financial institution which, at times may exceed the Federal Depository Insurance Corporation coverage limit of $250,000, and any investments held in Trust Account. At December 31, 2022 and 2021, the Company had not experienced losses on these accounts and management believes the Company is not exposed to significant risks on such account.

Investments Held in Trust Account

The Company’s portfolio of investments is comprised of U.S. government securities, within the meaning set forth in Section 2(a)(16) of the Investment Company Act, with a maturity of 185 days or less, or investments in money market funds that invest in U.S. government securities and generally have a readily determinable fair value, or a combination thereof. When the Company’s investments

held in the Trust Account are comprised of U.S. government securities, the investments are classified as trading securities. When the Company’s investments held in the Trust Account are comprised of money market funds, the investments are recognized at fair value. Trading securities and investments in money market funds are presented on the consolidated balance sheets at fair value at the end of each reporting period. Gains and losses resulting from the change in fair value of these securities is included in investment income on Trust Account in the accompanying consolidated statements of operations. The estimated fair values of investments held in the Trust Account are determined using available market information.

Fair Value of Financial Instruments

The fair value of the Company’s assets and liabilities which qualify as financial instruments under the FASB ASC Topic 820, “Fair Value Measurements” (“ASC 820”), equal or approximate the carrying amounts represented in the consolidated balance sheets, primarily due to their short-term nature, or because the instrument is recognized at fair value.

Fair Value Measurements

Fair value is defined as the price that would be received for sale of an asset or paid for transfer of a liability, in an orderly transaction between market participants at the measurement date. GAAP establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). These tiers consist of:

In some circumstances, the inputs used to measure fair value might be categorized within different levels of the fair value hierarchy. In those instances, the fair value measurement is categorized in its entirety in the fair value hierarchy based on the lowest level input that is significant to the fair value measurement.

Derivative Financial Instruments

The Company does not use derivative instruments to hedge exposures to cash flow, market, or foreign currency risks. The Company evaluates all of its financial instruments, including funded loans and issued share purchase warrants, to determine if such instruments are derivatives or contain features that qualify as embedded derivatives, pursuant to ASC 480 and FASB ASC Topic 815, “Derivatives and Hedging” (“ASC 815”). The classification of derivative instruments, including whether such instruments should be recorded as liabilities or as equity, is re-assessed at the end of each reporting period.

The warrants issued in connection with the Initial Public Offering (the “Public Warrants”) and the Private Placement Warrants are recognized as derivative liabilities in accordance with ASC 815. Accordingly, the Company recognizes the warrant instruments as liabilities at fair value and adjust the instruments to fair value at each reporting period. The liabilities are subject to re-measurement at each balance sheet date until exercised, and any change in fair value is recognized in the Company’s consolidated statements of operations. The fair value of the Public Warrants and the Private Placement Warrants were initially measured at fair value using a Monte Carlo simulation and a Black Scholes option pricing model, respectively. The fair value of the Private Placement Warrants continues to be measured using a Black-Scholes option pricing model. The fair value of the Public Warrants are subsequently measured at their listed

trading price since they began to be separately listed and traded beginning in September 2021. Derivative warrant liabilities are classified as non-current liabilities as their liquidation will not be reasonably expected to require the use of current assets or require the creation of current liabilities.

Offering Costs Associated with Initial Public Offering

Offering costs consisted of legal, accounting, underwriting fees and other costs incurred through the Initial Public Offering that were directly related to the Initial Public Offering. Offering costs are allocated to the separable financial instruments issued in the Initial Public Offering based on a relative fair value basis, compared to total proceeds received. Offering costs associated with derivative warrant liabilities were expensed as incurred and presented as non-operating expenses in the consolidated statements of operations. Offering costs associated with the Public Shares were charged to the carrying value of the Class A ordinary shares subject to possible redemption upon the completion of the Initial Public Offering. The Company classifies deferred underwriting commissions as non-current liabilities as their liquidation is not reasonably expected to require the use of current assets or require the creation of current liabilities.

Class A Ordinary Shares Subject to Possible Redemption

The Company accounts for its Class A ordinary shares subject to possible redemption in accordance with the guidance in ASC 480. Class A ordinary shares subject to mandatory redemption (if any) is classified as liability instruments and are measured at fair value. Conditionally redeemable Class A ordinary shares (including Class A ordinary shares that features redemption rights that are either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within the Company’s control) are classified as temporary equity. At all other times, Class A ordinary shares is classified as shareholders’ equity. The Company’s Class A ordinary shares feature certain redemption rights that are considered to be outside of the Company’s control and subject to the occurrence of uncertain future events. As of December 31, 2022 and 2021, 13,800,000 shares of Class A ordinary shares are subject to possible redemption and are presented at redemption value as temporary equity, outside of the shareholders’ equity section of the Company’s consolidated balance sheets.

The Company recognizes changes in redemption value immediately as they occur and adjusts the carrying value of the Class A ordinary shares subject to possible redemption to equal the redemption value at the end of each reporting period. Effective with the closing of the Initial Public Offering (including the exercise of the over-allotment option), the Company recognized the fair value adjustment from initial book value to redemption amount, which resulted in charges against additional paid-in capital (to the extent available) and accumulated deficit.

Income Taxes

FASB ASC Topic 740 prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more-likely-than-not to be sustained upon examination by taxing authorities. The Company’s management determined that the Cayman Islands is the Company’s only major tax jurisdiction. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. There were no unrecognized tax benefits and no amounts accrued for interest and penalties as of December 31, 2022 and 2021. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position.

There is currently no taxation imposed on income by the Government of the Cayman Islands. In accordance with Cayman federal income tax regulations, income taxes are not levied on the Company. Consequently, income taxes are not reflected in the Company’s consolidated financial statements. The Company’s management does not expect that the total amount of unrecognized tax benefits will materially change over the next twelve months.

Net Income (Loss) Per Ordinary Share

The Company complies with accounting and disclosure requirements of FASB ASC Topic 260, “Earnings Per Share.” The Company has two classes of shares, which are referred to as Class A ordinary shares and Class B ordinary shares. Income and losses are shared pro rata between the two classes of shares. Net income (loss) per ordinary share is calculated by dividing the net income by the weighted average ordinary shares outstanding for the respective period.

The calculation of diluted net income per share does not consider the effect of the warrants issued in connection with the Initial Public Offering (including exercise of the over-allotment option) and the Private Placement to purchase an aggregate of 12,810,000 ordinary shares because their exercise is contingent upon future events. The number of weighted average Class B ordinary shares for calculating basic net income per ordinary share was reduced for the effect of an aggregate of 450,000 Class B ordinary shares that were subject to forfeiture if the over-allotment option was not exercised in full or part by the underwriters in the period from March 10, 2021 (inception) through December 31, 2021 (see Note 4). Since the contingency was satisfied as of January 1, 2022, the Company included these shares in the weighted average number as of the beginning of the year ended December 31, 2022 to determine the dilutive impact of these shares. The fair value adjustment associated with the redeemable Class A ordinary shares is excluded from earnings per share as the redemption value approximates fair value.

The following tables presents a reconciliation of the numerator and denominator used to compute basic and diluted net income (loss) per share for each class of ordinary shares.
