AVISTA PUBLIC ACQUISITION CORP. II

NOTE 1. DESCRIPTION OF ORGANIZATION AND BUSINESS OPERATIONS, LIQUIDITY, AND GOING CONCERN CONSIDERATION

Avista Public Acquisition Corp. II was a blank check company incorporated in the Cayman Islands on February 5, 2021. As used herein, the references to the “Company” are to Avista Public Acquisition Corp. II, prior to its domestication as a corporation incorporated in the state of Delaware and change of name to OmniAb, Inc., and its then wholly-owned and controlled subsidiary, Orwell Merger Sub Inc. (“Merger Sub”), unless the context indicates otherwise. The Company was formed for the purpose of entering into a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses (a “Business Combination”). The Company was not limited to a particular industry or geographic region for purposes of consummating a Business Combination. The Company was an early stage and emerging growth company and, as such, the Company was subject to all of the risks associated with early stage and emerging growth companies.

As of September 30, 2022, the Company had not commenced any operations. All activity for the period from February 5, 2021 (inception) through September 30, 2022 related to the Company’s formation and the initial public offering (“Initial Public Offering”), and since the closing of the Initial Public Offering, the search for a prospective initial Business Combination, which is described below. The Company generated non-operating income in the form of interest and dividend income or gains on investments on the cash and investments held in the Trust Account (as defined below) from the proceeds derived from the Initial Public Offering. The Company had selected December 31 as its fiscal year end.

The registration statement for the Company’s Initial Public Offering was declared effective on August 9, 2021. On August 12, 2021, the Company consummated the Initial Public Offering of 23,000,000 units (the “Units” and, with respect to the Class A ordinary shares included in the Units sold, the “Public Shares”), including 3,000,000 Units that were issued pursuant to the underwriter’s exercise of its over-allotment option in full, at $10.00 per Unit, generating gross proceeds of $230,000,000 (see Note 3).

Simultaneously with the closing of the Initial Public Offering, the Company consummated the sale of 8,233,333 warrants (the “Private Placement Warrants”), including 900,000 Private Placement Warrants that were issued pursuant to the underwriter’s exercise of its over-allotment option in full, at a price of $1.50 per Private Placement Warrant in a private placement to Avista Acquisition LP II (the “Sponsor”), generating gross proceeds of $12,350,000 (see Note 4).

As of September 30, 2022, cash of $19,847 was held outside of the Trust Account and was available for the payment of accrued offering costs and for working capital purposes.

Upon closing of the Initial Public Offering and the sale of the Private Placement Warrants, a total of $235,750,000 ($10.25 per Public Share) was placed in a trust account (the “Trust Account”) and invested in only in U.S. government treasury obligations with maturities of 185 days or less or in money market funds meeting certain conditions under Rule 2a-7 under the Investment Company Act which invest only in direct U.S. government treasury obligations, until the earlier of: (i) the consummation of the initial Business Combination within 18 months from the closing of the Initial Public Offering, (ii) the redemption of the Company’s Public Shares if the Company had not consummated an Business Combination within 18 months from the closing of the Company’s Initial Public Offering, subject to applicable law, and (iii) the redemption of the Company’s Public Shares properly submitted in connection with a shareholder vote to approve an amendment to the Amended and Restated Memorandum and Articles of Association (A) that would modify the substance or timing of the obligation to provide holders of the Class A ordinary shares the right to have their shares redeemed in connection with the initial Business Combination or to redeem 100% of the Company’s Public Shares if the Company did not complete the initial Business Combination within 18 months from the closing the Company’s Initial Public Offering or (B) with respect to any other provision relating to the rights of holders of the Class A ordinary shares.

SEPTEMBER 30, 2022

The Company provided its holders of the outstanding 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 shareholder meeting called to approve the Business Combination or (ii) by means of a tender offer. The decision was made by the Company to seek shareholder approval of a Business Combination. The Public Shareholders were entitled to redeem their Public Shares for a pro rata portion of the amount then in the Trust Account ($10.25 per Public Share, plus any pro rata interest and dividends or gains on investments earned on the funds held in the Trust Account and not previously released to the Company to pay its tax obligations). There were no redemption rights upon the completion of a Business Combination with respect to the Company’s warrants. The Public Shares subject to redemption was recorded at redemption value and classified as temporary equity upon the completion of the Initial Public Offering in accordance with the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”) Topic 480, Distinguishing Liabilities from Equity (“ASC 480”).

The Company proceeded with the Business Combination as the Company had net tangible assets of at least $5,000,001 upon consummation of the Business Combination and at least two-thirds of the shares voted were voted in favor of the Business Combination. As the Company decided to obtain shareholder approval the Company offered to redeem shares in conjunction with the proxy solicitation pursuant to the proxy rules and not pursuant to the tender offer rules. The Sponsor agreed to vote its Founder Shares (as defined in Note 5) and any Public Shares purchased during or after the Initial Public Offering in favor of the Business Combination. Additionally, each Public Shareholder was given the option to redeem their Public Shares irrespective of whether they voted for or against the proposed transaction or didn’t vote at all.

The Sponsor agreed to waive (i) redemption rights with respect to its Founder Shares and Public Shares held by it in connection with the completion of the Business Combination, (ii) redemption rights with respect to any Founder Shares and Public Shares held by it in connection with the shareholder vote to amend the Amended and Restated Memorandum and Articles of Association to modify the substance or timing of the Company’s obligation to allow redemption in connection with an initial Business Combination or to redeem 100% of its Public Shares if the Company did not complete an initial Business Combination within 18 months from the closing of the Initial Public Offering or with respect to any other material provision relating to shareholders’ rights or pre-initial Business Combination activity and (iii) rights to liquidating distributions from the Trust Account with respect to any Founder Shares held if the Company failed to complete an initial Business Combination within 18 months from the closing of the Initial Public Offering. However, if the Sponsor had acquired Public Shares in or after the Initial Public Offering, such Public Shares would have been be entitled to liquidating distributions from the Trust Account if the Company failed to complete a Business Combination within 18 months from the closing of the Initial Public Offering.

The Company had until 18 months from the closing of the Initial Public Offering to complete a Business Combination (the “Combination Period”). If the Company was unable to complete a Business Combination within the Combination Period, the Company would have (i) ceased all operations except for the purpose of winding up; (ii) as promptly as reasonably possible but no more than ten business days thereafter, redeemed 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 and not previously released to the Company to pay income taxes, if any (less up to $100,000 of interest to pay dissolution expenses) divided by the number of the then-outstanding Public Shares, which redemption would have completely extinguished Public Shareholders’ rights as shareholders (including the right to receive further liquidation distributions, if any); and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the Company’s remaining shareholders and board of directors, liquidated and dissolved, subject in each case to the Company’s obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable law. There would have been be no redemption rights or liquidating distributions with respect to the Company’s warrants, which would have expired worthless if the Company failed to complete a Business Combination within the Combination Period.

The underwriters have agreed to waive their rights to a portion of their deferred underwriting commission (see Note 6) held in the Trust Account in the event the Company did not complete a Business Combination within the Combination Period and, in such event, such amounts would have been included with the other funds held in the Trust Account that would have been available to fund the redemption of the Public Shares.

OmniAb Business Combination

On March 23, 2022, the Company entered into an Agreement and Plan of Merger (the “Merger Agreement”), by and among the Company, Ligand Pharmaceuticals Incorporated, a Delaware corporation (“Ligand”), OmniAb, Inc., a Delaware corporation and then wholly-owned subsidiary of Ligand (“Legacy OmniAb”), and Orwell Merger Sub Inc. (“Merger Sub”), pursuant to which the Company combined with Legacy OmniAb, Ligand’s antibody discovery business (the “OmniAb Business”), in a Reverse Morris Trust transaction. Also on March 23, 2022, and in connection with the execution of the Merger Agreement, (a) the Company, Ligand, Legacy OmniAb and Merger Sub entered into that certain Employee Matters Agreement, as amended by that certain Amended and Restated Employee Matters Agreement, dated as of August 18, 2022 (the “Employee Matters Agreement”), (b) Legacy OmniAb and the Sponsor entered into that certain Sponsor Insider Letter Agreement (the “Sponsor Insider Agreement”) with the Company and certain insiders of the Company (the “Insiders”) and (c) the Company amended and restated that certain previously disclosed Forward Purchase Agreement, dated August 9, 2021, by entering into the Amended and Restated Forward Purchase Agreement (the “A&R FPA”), by and among the Company, the Sponsor and Legacy OmniAb pursuant to which they consummated the OmniAb Business Combination.

Pursuant to a Separation and Distribution Agreement, dated as of March 23, 2022, among the Company, Ligand and Legacy OmniAb (the “Separation Agreement”), Ligand transferred the OmniAb Business, including certain related subsidiaries of Ligand, to Legacy OmniAb and, in connection therewith, distributed (the “Distribution”) to Ligand stockholders 100% of the common stock of Legacy OmniAb, par value $0.001 per share (the “Legacy OmniAb Common Stock”).

Immediately following the Distribution, in accordance with and subject to the terms and conditions of the Merger Agreement, Merger Sub merged with and into Legacy OmniAb (the “Merger”), with Legacy OmniAb continuing as the surviving company in the Merger and as a wholly-owned subsidiary of the Company.

The Merger Agreement, along with the Separation Agreement and the other transaction documents entered into in connection therewith, provided for, among other things, the consummation of the following transactions (collectively, the “OmniAb Business Combination”): (i) the Company redomiciled by way of continuation from the Cayman Islands to Delaware and domesticate as a Delaware corporation in accordance with Section 388 of the Delaware General Corporation Law and with Section 206 of the Cayman Islands Companies Act (As Revised) (the “Domestication”), (ii) Ligand transferred the OmniAb Business (the “Separation”) to its wholly-owned subsidiary, Legacy OmniAb, and contributed $15 million in capital thereto (less certain reimbursable transaction and other expenses), and (iii) following the Separation, Ligand distributed 100% of the shares of Legacy OmniAb Common Stock to Ligand stockholders by way of the Distribution. Following the completion of the foregoing transactions and subject to the satisfaction or waiver of certain other conditions set forth in the Merger Agreement, the parties consummated the Merger. The Distribution and Merger are intended to qualify as “tax-free” transactions.

On April 28, 2022, the Company filed a registration statement on Form S-4 (File No. 333-264525) (the “Form S-4”, as amended on June 13, 2022, July 26, 2022, August 22, 2022, September 13, 2022 and September 27, 2022) with the SEC, which includes the proxy statement/prospectus/information statement distributed to holders of the Company’s ordinary shares in connection with the Company’s solicitation for proxies for the vote by the Company’s shareholders in connection with the OmniAb Business Combination and other matters as described in the Form S-4. The Form S-4 was declared effective by the SEC on September 30, 2022, and the definitive proxy statement/prospectus/information statement was mailed to the Company’s shareholders of record on the record date for voting on the OmniAb Business Combination. The OmniAb Business Combination closed on November 1, 2022. Upon consummation of the OmniAb Business Combination, and after the Domestication, the Company has one class of common stock, par value $0.0001 per share, which is listed on Nasdaq under the ticker symbol “OABI”. The Company’s warrants are listed on Nasdaq under the ticker symbol “OABIW”.

The Business Combination was accounted for as a reverse recapitalization in accordance with GAAP, whereby the Company is treated as the acquired company and Legacy OmniAb is treated as the acquirer. Accordingly, for accounting purposes, the Business Combination was treated as the equivalent of Legacy OmniAb issuing stock for the net assets of the Company, accompanied by a recapitalization. The net assets of the Company were stated at historical cost, with no goodwill or other intangible assets recorded. Subsequent presentations of the results of operations presented for the period prior to the Business Combination will be for those of Legacy OmniAb.

Legacy OmniAb has been determined to be the accounting acquirer in the Business Combination based on the following predominate factors:

Agreement and Plan of Merger

At the closing of the OmniAb Business Combination, each share of Legacy OmniAb’s common stock outstanding prior to the effective time of the OmniAb Business Combination was converted on a one-for-one basis into shares of common stock in the newly formed company (“OmniAb Common Stock”). Holders of Legacy OmniAb options, restricted stock units and performance stock units (determined after the Distribution (as defined below) and the division of Ligand equity awards into Ligand equity awards and OmniAb equity awards pursuant to the Employee Matters Agreement) had their awards converted into equity awards of the Company and adjusted pursuant to the exchange ratio.

In addition, at the closing of the OmniAb Business Combination, holders of Legacy OmniAb Common Stock and equity awards received shares of OmniAb Common Stock subject to certain price-based earnout triggers (“Earnout Shares”), with 50% of such Earnout Shares vesting upon the combined company’s achievement of a post-transaction volume-weighted average price (“VWAP”) of $12.50 per share of OmniAb Common Stock for any 20 trading days over a consecutive 30 trading-day period, and the remainder vesting upon achievement of a post-transaction VWAP of $15 per share of OmniAb Common Stock for any 20 trading days over a consecutive 30 trading-day period, in each case provided such vesting occurs during the five-year period following the closing of the OmniAb Business Combination.

In connection with the OmniAb Business Combination, upon the re-domestication of the Company to Delaware (i) all issued and outstanding Class A ordinary shares and Class B ordinary shares converted automatically, on a one-for-one basis, into shares of OmniAb Common Stock, (ii) all issued and outstanding warrants converted automatically into warrants to acquire shares of OmniAb Common Stock and (iii) all issued and outstanding Units separated and converted automatically into one share of OmniAb Common Stock and one-third of one warrant to purchase OmniAb Common Stock.

Separation and Distribution Agreement

On March 23, 2022, in connection with the execution of the Merger Agreement, the Company entered into the Seperation Agreement, pursuant to which the Separation and Distribution were effected.

The Separation Agreement also sets forth other agreements among Ligand and Legacy OmniAb, including provisions concerning the termination and settlement of intercompany accounts and the obtaining of necessary governmental approvals and third-party consents. The Separation Agreement also sets forth agreements that will govern certain aspects of the relationship between Ligand and Legacy OmniAb after the Distribution, including provisions with respect to release of claims, indemnification, access to financial and other information and access to and provision of records.

Employee Matters Agreement

On March 23, 2022, in connection with the execution of the Merger Agreement, the Company entered into the Employee Matters Agreement, as amended by the Amended and Restated Employee Matters Agreement, dated as of August 18, 2022, which provides for employee-related matters in connection with the transaction, including allocation of benefit plan assets and liabilities between Ligand and Legacy OmniAb, treatment of incentive equity awards in the Distribution and the OmniAb Business Combination and related covenants and commitments of the parties. Each existing Ligand equity award at the time of the Distribution granted prior to March 2, 2022, with certain limited exceptions, was split into (i) a new Ligand equity award and (ii) a new Legacy OmniAb equity award, with any in-the-money value in the original Ligand equity award split between such awards based on the relative values of Ligand and OmniAb at the time of the Distribution. Each existing Ligand equity award at the time of the Distribution granted on or after March 2, 2022 was converted into either an adjusted Ligand equity award, if the holder was a Ligand service provider following the Distribution, or a Legacy OmniAb equity award, if the holder was a Legacy OmniAb service provider following the Distribution.

Sponsor Insider Agreement

On March 23, 2022, in connection with the execution of the Merger Agreement, Legacy OmniAb and the Sponsor entered into the Sponsor Insider Agreement with the Company and the Insiders, pursuant to which, among other things, the Insiders agreed to vote any of our securities held by them to approve the OmniAb Business Combination and the other Company shareholder matters required pursuant to the Merger Agreement, and not to seek redemption of any of their Company securities in connection with the consummation of the OmniAb Business Combination. Pursuant to the Sponsor Insider Agreement, the Sponsor also agreed to subject up to 1,916,667 Earnout Founder Shares (as defined in the Sponsor Insider Agreement), to the same price-based vesting conditions as the OmniAb Earnout Shares.

Amended and Restated Forward Purchase Agreement

On March 23, 2022, in connection with the execution of the Merger Agreement, the Company entered into Amended and Restated Forward Purchase Agreement (the “A&R FPA”) with the Sponsor and Legacy OmniAb. Pursuant to the A&R FPA, the Company agreed to, in connection with the consummation of the OmniAb Business Combination, issue and sell to the Sponsor 1,500,000 shares of OmniAb Common Stock (the “Forward Purchase Shares”) and warrants to acquire 1,666,667 shares of OmniAb Common Stock (the “Forward Purchase Warrants”) for an aggregate purchase price of $15.0 million with such purchases having been consummated immediately following the re-domestication to Delaware. In addition, the Sponsor agreed to purchase up to an additional 10,000,000 shares of OmniAb Common Stock (the “Backstop Shares”) and up to an additional 1,666,667 warrants, (The “Backstop Warrants” and, together with the Forward Purchase Shares, Forward Purchase Warrants and Backstop Shares, the “Forward Purchase and Backstop Securities”) for an aggregate additional purchase price of up to $100.0 million, in order to backstop shareholder redemptions to the extent such redemptions would result in the cash proceeds to be received by OmniAb stockholders from the Trust Account to be less than $100.0 million. Pursuant to the A&R FPA, in connection with the Business Combination, the Sponsor was issued 8,672,934 Backstop Shares and 1,445,489 Backstop Warrants for an aggregate purchase price of $86,729,340 in order to backstop the redemptions. In addition, pursuant to the A&R FPA, the Sponsor was issued 1,500,000 Forward Purchase Shares and 1,666,667 Forward Purchase Warrants for an aggregate purchase price of $15,000,000, on a private placement basis.

Indemnity

In order to protect the amounts held in the Trust Account, the Sponsor has 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 (other than the Company’s independent registered public accounting firm), or a prospective target business with which the Company has discussed entering into a transaction agreement, reduce the amounts in the Trust Account to below the lesser of (i) $10.25 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 $10.25 per Public Share due to reductions in the value of the trust assets, in each case net of the interest that may be withdrawn to pay tax obligations, provided that such liability will not apply to any claims by a third party or prospective target business that executed a waiver of any and all rights to seek access to the Trust Account nor will it apply to any claims under the 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”). 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 all vendors, service providers (other than 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.

Liquidity and Going Concern Consideration

As of September 30, 2022, the Company had $19,847 in cash held outside of the Trust Account and a working capital deficit of $9,843,540. The Company incurred significant costs in pursuit of its acquisition plans. In connection with the Company’s assessment of going concern considerations in accordance with FASB’s ASC Subtopic 205-40, Presentation of Financial Statements - Going Concern, management has determined those conditions raised substantial doubt about the Company’s ability to continue as a going concern within the earlier of the Combination Period, which will end on February 12, 2023, or one year after the date that the condensed consolidated financial statements are issued. Moreover, the Company needed to obtain additional financing to complete the Business Combination and to redeem 21,713,864 public shares upon completion of the Business Combination, in which case the Company issued additional securities in connection with the Business Combination. Of the total proceeds from the Initial Public Offering and sale of the Private Placement Warrants, an amount of approximately $2 million was deposited in an operating account for the Company’s working capital needs. In addition, the Company entered into a convertible promissory note pursuant to the Working Capital Loans terms as outlined in Note 5 with the Sponsor (the “Sponsor Working Capital Loan”) to which the Company could borrow up to an aggregate of $750,000. As of September 30, 2022, the Company has borrowed $750,000 under the Sponsor Working Capital Loan. The amounts held in the operating account were not expected to provide the Company with sufficient funds to meet its operational and liquidity obligations over the remainder of the Combination Period. The condensed consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Risks and Uncertainties

Management continues to evaluate the impact of the COVID-19 pandemic on the industry, the geopolitical conditions resulting from the recent invasion of Ukraine by Russia and subsequent sanctions against Russia, Belarus and related individuals and entities and the status of debt and equity markets and has concluded that while it is reasonably possible that any of the foregoing could have a negative effect on the Company’s financial position and results of its operations, the specific impact is not readily determinable as of the date of these condensed consolidated financial statements. The condensed consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

​

On August 16, 2022, President Biden signed into law the Inflation Reduction Act of 2022, which, among other things, imposes a 1% excise tax on the fair market value of stock repurchased by publicly traded U.S. corporations and certain U.S. subsidiaries of publicly traded non- U.S. corporations beginning in 2023, with certain exceptions (the “Excise Tax”). Because the Company became a Delaware corporation upon the Domestication and the securities traded on Nasdaq, we would have likely been considered a “covered corporation” within the meaning of the Inflation Reduction Act. While not free from doubt, absent any further guidance from Congress or the U.S. Department of the Treasury, there is significant risk that the Excise Tax would have applied to any redemptions of our common stock after December 31, 2022, including redemptions in connection with an initial Business Combination and any amendment to a certificate of incorporation to extend the time to consummate an initial Business Combination, unless an exemption is available.

NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The accompanying condensed consolidated financial statements of the Company are presented in conformity with accounting principles generally accepted in the United States of America (“GAAP”) and pursuant to the rules and regulations of the SEC. Certain information or footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted, pursuant to the rules and regulations of the SEC for interim financial reporting. Accordingly, they do not include all the information and footnotes necessary for a comprehensive presentation of financial position, results of operations, or cash flows. In the opinion of management, the accompanying condensed consolidated financial statements include all adjustments, consisting of a normal recurring nature, which are necessary for a fair presentation of the financial position, operating results and cash flows for the periods presented. The accompanying condensed consolidated financial statements should be read in conjunction with the Company’s Form 10-K as filed with the SEC on March 28, 2022. The interim results for the three and nine months ended September 30, 2022 are not necessarily indicative of the results to be expected for the year ending December 31, 2022 or for any future periods.

Principles of Consolidation

The accompanying condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary. All significant intercompany balances and transactions have been eliminated in consolidation.

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 independent registered public accounting firm attestation requirements of Section 404 of the Sarbanes-Oxley Act, 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 a 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 condensed consolidated financial statements 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.

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 and the reported amounts of expenses during the reporting period.

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 condensed 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 from those estimates. The valuation of the Forward Purchase and Backstop Securities required management to exercise significant judgement in its estimate.

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. The Company did not have any cash equivalents as of September 30, 2022 or December 31, 2021. As of September 30, 2022 and December 31, 2021, the Company had operating cash (i.e., cash held outside the Trust Account) of $19,847 and $189,971, respectively.

Investments Held in Trust Account

At September 30, 2022, substantially all of the assets held in the Trust Account were held in U.S. Treasury bills. The Company’s investments held in the Trust Account are classified as trading securities. Trading securities are presented on the balance sheet at fair value at the end of each reporting period. Gains and losses resulting from the change in fair value of investments held in Trust Account are included in gain on investments held in Trust Account in the accompanying condensed consolidated statements of operations. The estimated fair values of the investments held in the Trust Account are determined using available market information. At December 31, 2021, the assets held in the Trust Account were held in cash.

Class A Ordinary Shares Previously Subject to Possible Redemption

All of the 23,000,000 shares of Class A ordinary shares sold as part of the Units in the Initial Public Offering contained a redemption feature which allowed for the redemption of such Public Shares in connection with the Company’s liquidation, and in connection with certain amendments to the Company’s amended and restated certificate of incorporation. In accordance with SEC and its staff’s guidance on redeemable equity instruments, which has been codified in ASC 480-10-S99, redemption provisions not solely within the control of the Company require ordinary shares subject to redemption to be classified outside of permanent equity. Therefore, all Class A ordinary shares have been classified outside of permanent equity.

The Company recognized changes in redemption value immediately as they occurred and adjusted the carrying value of redeemable ordinary shares to equal the redemption value at the end of each reporting period. Increases or decreases in the carrying amount of redeemable ordinary shares were affected by charges against additional paid-in capital and accumulated deficit.

As of September 30, 2022 and December 31, 2021, the Class A ordinary shares subject to possible redemption reflected in the balance sheet are reconciled in the following table:

​

​

On November 1, 2022, the parties to the Merger Agreement completed the Business Combination. Holders of 21,713,864 shares of the Company’s Class A Ordinary Shares sold in the Initial Public Offering exercised their right to redeem those shares for a pro rata portion of the Trust Account holding the proceeds from the Company’s Initial Public Offering, calculated as of two business days prior to the extraordinary general meeting of the shareholders, at a price of approximately $10.32 per share, for an aggregate of approximately $224 million.

Offering Costs Associated with the Initial Public Offering

The Company complies with the requirements of ASC 340-10-S99-1 and SEC Staff Accounting Bulletin Topic 5A - Expenses of Offering. Offering costs consist principally of professional and registration fees incurred through the balance sheet date that are related to the Initial Public Offering. Offering costs directly attributable to the issuance of an equity contract to be classified in equity are recorded as a reduction in equity. Offering costs for equity contracts that are classified as assets and liabilities are expensed immediately. The Company incurred offering costs amounting to $13,662,256 as a result of the Initial Public Offering (consisting of $4,600,000 of cash underwriting discounts, $8,050,000 in deferred underwriting fees and $1,012,256 of other offering costs). As such, the Company recorded $13,029,901 of offering costs as a reduction of temporary equity and $632,355 of offering costs as a reduction of permanent equity in connection with the issuance of the Units in the Initial Public Offering and the Private Placement Warrants.

Income Taxes

The Company accounts for income taxes under ASC 740, Income Taxes (“ASC 740”). ASC 740 requires the recognition of deferred tax assets and liabilities for both the expected impact of differences between the financial statement and tax basis of assets and liabilities and for the expected future tax benefit to be derived from tax loss and tax credit carry forwards. ASC 740 additionally requires a valuation allowance to be established when it is more likely than not that all or a portion of deferred tax assets will not be realized.

ASC 740 also clarifies the accounting for uncertainty in income taxes recognized in an enterprise’s condensed consolidated financial statements and prescribes a recognition threshold and measurement process for financial statement recognition and measurement of a tax position 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. ASC 740 also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. Based on the Company’s evaluation, it has been concluded that there are no significant uncertain tax positions requiring recognition in the Company’s condensed consolidated financial statements.

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 September 30, 2022 and December 31, 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. The Company is considered an exempted Cayman Islands Company and is presently not subject to income taxes or income tax filing requirements in the Cayman Islands or the United States. Consequently, income taxes are not reflected in the Company’s condensed consolidated financial statements.

Net Loss Per Ordinary Share

Net loss per ordinary share is computed by dividing net loss by the weighted average number of ordinary shares outstanding during the period. The Company has not considered the effect of the warrants sold in the Initial Public Offering and private placement to purchase an aggregate of 15,900,000 shares in the calculation of diluted income per share as the exercise of the warrants are contingent upon the occurrence of future events and the inclusion of such warrants would be anti-dilutive.

Table of Contents

The following table reflects the calculation of basic and diluted net loss per ordinary share (in dollars, except per share amounts):

​

​

Concentration of Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist of a cash account in a financial institution, which, at times, may exceed the Federal Depository Insurance Coverage of $250,000. The Company has not experienced losses on this account and management believes the Company is not exposed to significant risks on such account.

Derivative Financial Instruments

The Company evaluates its financial instruments to determine if such instruments are derivatives or contain features that qualify as embedded derivatives in accordance with ASC Topic 815, Derivatives and Hedging. For derivative financial instruments that are accounted for as assets or liabilities, the derivative instrument is initially recorded at its fair value on the grant date and is then re-valued at each reporting date, with changes in the fair value reported in the condensed consolidated statements of operations. The classification of derivative instruments, including whether such instruments should be recorded as liabilities or as equity, is evaluated at the end of each reporting period. The Forward Purchase and Backstop Securities contained within the A&R FPA (see Note 6) are classified as derivatives in the condensed consolidated balance sheet with changes in the fair value recognized in the condensed consolidated statements of operations.

Fair Value of Financial Instruments

The Company applies ASC Topic 820, Fair Value Measurement (“ASC 820”), which establishes a framework for measuring fair value and clarifies the definition of fair value within that framework. ASC 820 defines fair value as an exit price, which is the price that would be received for an asset or paid to transfer a liability in the Company’s principal or most advantageous market in an orderly transaction between market participants on the measurement date. The fair value hierarchy established in ASC 820 generally requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Observable inputs reflect the assumptions that market participants would use in pricing the asset or liability and are developed based on market data obtained from sources independent of the reporting entity. Unobservable inputs reflect the entity’s own assumptions based on market data and the entity’s judgments about the assumptions that market participants would use in pricing the asset or liability and are to be developed based on the best information available in the circumstances.

The carrying amounts reflected in the balance sheet for cash, deferred offering costs, accrued offering costs, promissory note - related party, and advance from anchor investor approximate fair value due to their short-term nature.

Level 1 — Assets and liabilities with unadjusted, quoted prices listed on active market exchanges. Inputs to the fair value measurement are observable inputs, such as quoted prices in active markets for identical assets or liabilities.

14

Table of Contents

AVISTA PUBLIC ACQUISITION CORP. II

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

SEPTEMBER 30, 2022

Level 2 — Inputs to the fair value measurement are determined using prices for recently traded assets and liabilities with similar underlying terms, as well as direct or indirect observable inputs, such as interest rates and yield curves that are observable at commonly quoted intervals.

Level 3 — Inputs to the fair value measurement are unobservable inputs, such as estimates, assumptions, and valuation techniques when little or no market data exists for the assets or liabilities.

Recent Accounting Pronouncements

Management does not believe that any recently issued, but not yet effective, accounting standards, if currently adopted, would have a material effect on the Company’s condensed consolidated financial statements.

​

NOTE 3. INITIAL PUBLIC OFFERING

The registration statement for the Company’s Initial Public Offering was declared effective on August 9, 2021. On August 12, 2021, the Company completed its Initial Public Offering of 23,000,000 Units, including 3,000,000 Units that were issued pursuant to the underwriter’s exercise of its over-allotment option in full, at $10.00 per Unit, generating gross proceeds of $230,000,000. Each Unit consists of one Class A ordinary share and one-third of one redeemable warrant (“Public Warrant”). Each Public Warrant entitles the holder to purchase one Class A ordinary share at an exercise price of $11.50 per whole share (see Note 7).

​

NOTE 4. PRIVATE PLACEMENT

Simultaneously with the closing of the Initial Public Offering, the Sponsor purchased an aggregate of 8,233,333 Private Placement Warrants, including 900,000 Private Placement Warrants that were issued pursuant to the underwriter’s exercise of its over-allotment option in full, at a price of $1.50 per Private Placement Warrant ($12,350,000 in the aggregate). Each Private Placement Warrant was exercisable to purchase one Class A ordinary share at a price of $11.50 per share. The proceeds from the Private Placement Warrants were added to the net proceeds from the Initial Public Offering to be held in the Trust Account. If the Company did not complete a Business Combination within the Combination Period, the proceeds from the sale of the Private Placement Warrants would have been used to fund the redemption of the Public Shares (subject to the requirements of applicable law) and the Private Placement Warrants would have expired worthless.

​

NOTE 5. RELATED PARTY TRANSACTIONS

Founder Shares

On February 12, 2021, the Sponsor paid an aggregate of $25,000 to cover certain expenses on behalf of the Company in exchange for the issuance of 5,750,000 Class B ordinary shares (the “Founder Shares”). The Founder Shares included an aggregate of up to 750,000 Class B ordinary shares subject to forfeiture by the Sponsor to the extent that the underwriters’ over-allotment option was not exercised in full or in part, so that the holders of the Founder Shares would own, on an as-converted basis, 20% of the Company’s issued and outstanding shares after the Initial Public Offering. On June 16, 2021, the Company transferred 35,000 Class B ordinary shares each to three members of the Company’s board of directors (or 105,000 Class B ordinary shares in total) at their original cost (see Note 7). The underwriters exercised their over-allotment option in full on August 12, 2021; thus, no ordinary shares remain subject to forfeiture (see Note 6).

The Sponsor has agreed that, subject to certain limited exceptions, the Founder Shares will not be transferred, assigned, or sold until the earlier of (i) one year after the completion of a Business Combination or (ii) the date on which the Company completes a liquidation, merger, share exchange or other similar transaction after an initial Business Combination that results in all of the Company’s shareholders having the right to exchange their Class A ordinary shares for cash, securities or other property. Notwithstanding the foregoing, if (1) the closing price of the Company’s 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 OmniAb Business Combination or (2) if the Company consummates a transaction after the OmniAb Business Combination which results in the Company’s shareholders having the right to exchange their shares for cash, securities or other property, the Founder Shares will be released from the lock-up.

Promissory Note — Related Party

On February 12, 2021, the Company issued an unsecured promissory note to the Sponsor (the “Promissory Note”), pursuant to which the Company could borrow up to an aggregate of $300,000 to cover expenses related to the Initial Public Offering. The Promissory Note was non-interest bearing and was payable on the earlier of (i) December 31, 2021 or (ii) the consummation of the Initial Public Offering. The Company’s Sponsor paid certain offering costs totaling $55,725, which was included in the outstanding balance of the Promissory Note as of March 22, 2021, and the Company borrowed $119,275 on June 23, 2021. On August 12, 2021, the Company repaid the outstanding balance under the Promissory Note of $175,000. The Promissory Note is no longer available to the Company.

Administrative Support Agreement

The Company entered into an agreement, commencing on August 9, 2021, to pay an affiliate of the Sponsor a total of $10,000 per month for administrative, financial and support services. Upon the completion of the OmniAb Business Combination, the Company ceased paying these monthly fees. For the three months and nine months ended September 30, 2022, the Company incurred expenses of $30,000 and $90,000, respectively, under the agreement. For the three months ended September 30, 2021 and for the period from February 5, 2021 (inception) through September 30, 2021 the Company incurred expenses of $20,000 under the agreement.

Due to Related Party

Due to related party consists of payments made by the Sponsor and/or an affiliate of the Sponsor on behalf of the Company for formation and operating costs, along with the administrative support monthly fee and are payable on demand.

Convertible Promissory Note

In order to finance transaction costs in connection with an intended initial 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, loan the Company funds as may be required (the “working capital loans”). If the Company completed the initial Business Combination, it could repay such loaned amounts out of the proceeds of the Trust Account released to us. Otherwise, such loans could be repaid only out of funds held outside the Trust Account. In the event that the initial Business Combination did not close, the Company could use a portion of the working capital held outside the Trust Account to repay such loaned amounts but no proceeds from the Company’s Trust Account would be used to repay such loaned amounts. Up to $2,000,000 of such loans could have been convertible into warrants of the post-Business Combination entity at a price of $1.50 per warrant at the option of the lender. The warrants would have been identical to the Private Placement Warrants. Except as set forth above, the terms of such loans, if any, have not been determined and no written agreements exist with respect to such loans. The Company did not seek loans from parties other than the Sponsor, its affiliates or any members of the management team as the Company did not believe third parties would be willing to loan such funds and provide a waiver against any and all rights to seek access to funds in the Trust Account.

On March 14, 2022, the Company entered into a convertible promissory note pursuant to the Working Capital Loans terms with the Sponsor (the “Sponsor Working Capital Loan”) to which the Company could borrow up to an aggregate of $750,000. The Sponsor Working Capital Loan is non-interest bearing and payable upon the earlier of (i) completion of the initial Business Combination or (ii) the date that the winding up of the Company is effective. The unpaid principal balance on the Sponsor Working Capital Loan may be convertible into warrants at the option of the Sponsor at a price of $1.50 per warrant. The warrants would be identical to the Private Placement Warrants. As of September 30, 2022, the outstanding balance on the convertible promissory note is $750,000.

Audit Committee Compensation

​

On August 24, 2022, the board of directors elected Charles Harwood to serve as a director of the Company and appointed Mr. Harwood to serve as a member of the audit committee. The board of directors has determined that Mr. Harwood satisfies all applicable independence requirements to serve on the board of directors and the audit committee, including without limitation the applicable independence requirements of the Nasdaq Capital Market and the Exchange Act, as amended. In connection with Mr. Harwood’s appointment to the audit committee, Lâle White has stepped down from the audit committee, which currently consists of Wendel Barr, Charles Harwood and William Klitgaard. The changes to the audit committee’s composition relate to the Company’s communications with the staff of Nasdaq on August 22, 2022, regarding whether the Company was in compliance with Nasdaq Listing Rule 5605(c)(2) following the phase-in period provided under Nasdaq Listing Rule 5615(b)(1) because the Audit Committee was not comprised of at least three independent directors. The Company is in compliance with the applicable rules following the board of directors and audit committee changes described herein.

​

Upon consummation of the OmniAb Business Combination, the Company paid Mr. Harwood a $10,000 fee for his services as a director and member of the audit committee. This fee is included as part of accrued expenses on the balance sheet as of September 30, 2022. In connection with Mr. Harwood’s appointment, he and the Company entered into an indemnification agreement and a letter agreement, the terms of which were described in, and the forms of which were filed as exhibits to, the Company’s registration statement relating to the Company’s Initial Public Offering.

NOTE 6. COMMITMENTS AND CONTINGENCIES

Registration and Shareholder Rights Agreement

Pursuant to a registration rights agreement entered into on August 9, 2021, the holders of the Founder Shares, Private Placement Warrants and warrants that may be issued upon conversion of Working Capital Loans (and any Class A ordinary shares issuable upon the exercise of the Private Placement Warrants and warrants issued upon conversion of the Working Capital Loans) had registration and shareholder rights to require the Company to register a sale of any of its securities held by them pursuant to a registration and shareholder rights agreement to be signed prior to or on the effective date of the Initial Public Offering. The holders of these securities were entitled to make up to three demands, excluding short form demands, that the Company register such securities. In addition, the holders have certain “piggy-back” registration rights with respect to registration statements filed subsequent to the completion of an initial Business Combination.

Underwriting Agreement

The underwriters purchased Units at a purchase price of $9.80 per Unit (i.e., at a cash underwriting discount of $0.20 per Unit, or $4,600,000 in the aggregate) upon the closing of the Initial Public Offering and the exercise of the over-allotment in full on August 12, 2021. In addition, the Company agreed to pay the underwriters a deferred underwriting fee of up to $0.35 per Unit, or $8,050,000 in the aggregate, which would be payable to the underwriters upon the consummation of the initial Business Combination, except that the Company’s management team would be permitted, in its sole discretion, to allocate up to 50% of the deferred underwriting fee, or $4,025,000 in the aggregate, to third parties that assist in identifying and consummating an initial Business Combination. On August 17, 2022, Credit Suisse waived its right to 50%, or $4,025,000 in the aggregate, of the deferred underwriting fee, and the Company has determined not to pay the 50% to any other advisors.

Forward Purchase Agreement

In connection with the consummation of the Initial Public Offering, the Company entered into a forward purchase agreement with the Sponsor which provides for the purchase of an aggregate of 10,000,000 Class A ordinary shares plus an aggregate of 3,333,333 redeemable warrants to purchase Class A ordinary shares at $11.50 per share, for an aggregate purchase price of $100,000,000, in the private placement. The obligations under the forward purchase agreement do not depend on whether any Class A ordinary shares are redeemed by the Company’s Public Shareholders.

The forward purchase securities were issued in connection with the closing of the initial Business Combination. The proceeds from the sale of forward purchase securities were used as part of the consideration to the sellers in the Company’s initial Business Combination, expenses in connection with the initial Business Combination or for working capital in the post-transaction company.

On March 23, 2022, in connection with the execution of the Merger Agreement, the Company entered into the A&R FPA with the Sponsor and Legacy OmniAb. Pursuant to the A&R FPA, the Company agreed that, in connection with the consummation of the OmniAb Business Combination, they would issue and sell to the Sponsor 1,500,000 shares of OmniAb Common Stock and warrants to acquire 1,666,667 shares of OmniAb Common Stock for an aggregate purchase price of $15.0 million with such purchases to be consummated immediately following the re-domestication to Delaware and prior to the OmniAb Business Combination. In addition, the Sponsor agreed to purchase up to an additional 10,000,000 shares of OmniAb Common Stock and up to an additional 1,666,667 warrants, for an aggregate additional purchase price of up to $100.0 million, in order to backstop shareholder redemptions to the extent such redemptions would result in the cash proceeds to be received by OmniAb stockholders from the Trust Account to be less than $100.0 million. The A&R FPA also provided that in the event the Merger Agreement was terminated by Ligand under circumstances in which the Termination Fee (as defined in the Merger Agreement) would be payable under the Merger Agreement, Ligand would pay the Sponsor a termination fee of $12.5 million in connection therewith. Pursuant to the A&R FPA, in connection with the Business Combination, the Sponsor was issued 8,672,934 Backstop Shares and 1,445,489 Backstop Warrants for an aggregate purchase price of $86,729,340 in order to backstop the redemptions. In addition, pursuant to the A&R FPA, the Sponsor was issued 1,500,000 Forward Purchase Shares and 1,666,667 Forward Purchase Warrants for an aggregate purchase price of $15,000,000, on a private placement basis.

As a result of the A&R FPA, the Company evaluated the modification of the equity contract, which resulted in a reclassification between equity and a liability, in which the difference between the fair value at issuance of the original forward purchase agreement and the fair value at issuance of the A&R FPA (the modification date) was treated as a deemed dividend. An amount of $225,000 was recorded to accumulated deficit as a deemed dividend upon modification of the forward purchase agreement on March 23, 2022.

Ordinary shareholders of record are entitled to one vote for each share held on all matters to be voted on by shareholders. Except as described below, holders of Class A ordinary shares and holders of Class B ordinary shares will vote together as a single class on all matters submitted to a vote of the Company’s shareholders except as required by law. Unless specified in the Company’s Amended and Restated Memorandum and Articles of Association, or as required by applicable provisions of the Companies Act or applicable stock exchange rules, the affirmative vote of a majority of the ordinary shares that are voted is required to approve any such matter voted on by the shareholders. Approval of certain actions will require a special resolution under Cayman Islands law, being the affirmative vote of at least two-thirds of the ordinary shares that are voted, and pursuant to the Amended and Restated Memorandum and Articles of Association; such actions include amending the Amended and Restated Memorandum and Articles of Association and approving a statutory merger or consolidation with another company. The Company’s board of directors is divided into three classes, each of which will generally serve for a term of three years with only one class of directors being appointed in each year. There is no cumulative voting with respect to the appointment of directors, with the result that the holders of more than 50% of the shares voted for the appointment of directors can appoint all of the directors. The Company’s shareholders are entitled to receive ratable dividends when, as and if declared by the board of directors out of funds legally available therefor. Prior to the Company’s initial Business Combination, (i) only holders of the founder shares will have the right to vote on the appointment of directors and (ii) in a vote to continue the Company in a jurisdiction outside the Cayman Islands (which requires the approval of at least two thirds of the votes of all ordinary shares), holders of the Company’s Class B ordinary shares will have ten votes for every Class B ordinary share and holders of the Class A ordinary shares will have one vote for every Class A ordinary share. These provisions of the Company’s Amended and Restated Memorandum and Articles of Association may only be amended by a special resolution passed by not less than 90% of the ordinary shares who attend and vote at the Company’s general meeting which shall include the affirmative vote of a simple majority of the Class B ordinary shares. Holders of the public shares will not be entitled to vote on the appointment of directors prior to the initial Business Combination. In addition, prior to the completion of an initial Business Combination, holders of a majority of the founder shares may remove a member of the board of directors for any reason. In connection with the initial Business Combination, the Company may enter into a shareholders agreement or other arrangements with the shareholders of the target with respect to voting and other corporate governance matters following completion of the initial Business Combination.

Redeemable Warrants — Each whole warrant entitles the registered holder to purchase one Class A ordinary share at a price of $11.50 per share, subject to adjustment as discussed below, at any time commencing 30 days after the completion of the Company’s initial Business Combination, except as discussed in the immediately succeeding paragraph. Pursuant to the warrant agreement, a warrant holder may exercise its warrants only for a whole number of Class A ordinary shares. This means only a whole warrant may be exercised at a given time by a warrant holder. No fractional warrants will be issued upon separation of the units and only whole warrants will trade. Accordingly, unless you purchase at least three units, you will not be able to receive or trade a whole warrant. The warrants will expire five years after the completion of the initial Business Combination, at 5:00 p.m., New York City time, or earlier upon redemption or liquidation.

The Company will not be obligated to deliver any Class A ordinary shares pursuant to the exercise of a warrant and will have no obligation to settle such warrant exercise unless a registration statement under the Securities Act with respect to the Class A ordinary shares underlying the warrants is then effective and a prospectus relating thereto is current, subject to the Company’s satisfying of the obligations described below with respect to registration, or a valid exemption from registration is available. No warrant will be exercisable and the Company will not be obligated to issue a Class A ordinary share upon exercise of a warrant unless the Class A ordinary share issuable upon such warrant exercise has been registered, qualified or deemed to be exempt under the securities laws of the state of residence of the registered holder of the warrants. In the event that the conditions in the two immediately preceding sentences are not satisfied with respect to a warrant, the holder of such warrant will not be entitled to exercise such warrant and such warrant may have no value and expire worthless. In no event will the Company be required to net cash settle any warrant. In the event that a registration statement is not effective for the exercised warrants, the purchaser of a unit containing such warrant will have paid the full purchase price for the unit solely for the Class A ordinary share underlying such unit.

The Company has agreed that as soon as practicable, but in no event later than 20 business days after the closing of the initial Business Combination, the Company will use commercially reasonable efforts to file with the SEC a registration statement (which may be a post-effective amendment to the registration statement of which the Company’s prospectus is a part or any other applicable registration statement) for the registration, under the Securities Act, of the Class A ordinary shares issuable upon exercise of the warrants, and the Company will use commercially reasonable efforts to cause the same to become effective within 60 business days after the closing of the initial Business Combination, and to maintain the effectiveness of such registration statement and a current prospectus relating to those Class A ordinary shares until the warrants expire or are redeemed, as specified in the warrant agreement; provided that if the Company’s Class A ordinary shares are at the time of any exercise of a warrant not listed on a national securities exchange such that they satisfy the definition of a “covered security” under Section 18(b)(1) of the Securities Act, the Company may, at it’s option, require holders of warrants who exercise their warrants to do so on a “cashless basis” in accordance with Section 3(a)(9) of the Securities Act and, in the event the Company so elects, will not be required to file or maintain in effect a registration statement, and will use commercially reasonably efforts to register or qualify the shares under applicable blue sky laws to the extent available. If a registration statement covering the Class A ordinary shares issuable upon exercise of the warrants is not effective by the 60th day after the closing of the initial Business Combination, warrant holders may, until such time as there is an effective registration statement and during any period when the Company will have failed to maintain an effective registration statement, exercise warrants on a “cashless basis” in accordance with Section 3(a)(9) of the Securities Act or another exemption, and the Company will use commercially reasonably efforts to register or qualify the shares under applicable blue sky laws to the extent available. In such event, each holder would pay the exercise price by surrendering the warrants for that number of Class A ordinary shares equal to the quotient obtained by dividing (x) the product of the number of Class A ordinary shares underlying the warrants, multiplied by the excess of the “fair market value” (defined below) less the exercise price of the warrants by (y) the fair market value. The “fair market value” as used in this paragraph shall mean the volume weighted average price of the Class A ordinary shares for the 10 trading days ending on the trading day prior to the date on which the notice of exercise is received by the warrant agent.

Redemption of warrants

Once the warrants become exercisable, the Company may redeem the outstanding warrants (except as described herein with respect to the Private Placement Warrants):

The Company will not redeem the warrants as described above unless a registration statement under the Securities Act covering the issuance of the Class A ordinary shares issuable upon exercise of the warrants is then effective and a current prospectus relating to those Class A ordinary shares is available throughout the 30-day redemption period. If and when the warrants become redeemable by the Company, the Company may exercise the Company’s redemption right even if the Company is unable to register or qualify the underlying securities for sale under all applicable state securities laws.

The Company has established the last of the redemption criterion discussed above to prevent a redemption call unless there is at the time of the call a significant premium to the warrant exercise price. If the foregoing conditions are satisfied and the Company issues a notice of redemption of the warrants, each warrant holder will be entitled to exercise his, her or its warrant prior to the scheduled redemption date. However, the price of the Class A ordinary shares may fall below the $18.00 redemption trigger price (as adjusted for share subdivisions, share capitalizations, reorganizations, recapitalizations and the like) as well as the $11.50 (for whole shares) warrant exercise price after the redemption notice is issued.

No fractional Class A ordinary shares will be issued upon exercise. If, upon exercise, a holder would be entitled to receive a fractional interest in a share, the Company will round down to the nearest whole number of the number of Class A ordinary shares to be issued to the holder. If, at the time of redemption, the warrants are exercisable for a security other than the Class A ordinary shares pursuant to the warrant agreement (for instance, if the Company is not the surviving company in the Company’s initial Business Combination), the warrants may be exercised for such security. At such time as the warrants become exercisable for a security other than the Class A ordinary shares, the Company (or surviving company) will use its commercially reasonable efforts to register under the Securities Act the security issuable upon the exercise of the warrants.

If the number of outstanding Class A ordinary shares is increased by a capitalization or share dividend payable in Class A ordinary shares, or by a sub-division of ordinary shares or other similar event, then, on the effective date of such capitalization or share dividend, sub-division or similar event, the number of Class A ordinary shares issuable on exercise of each warrant will be increased in proportion to such increase in the outstanding ordinary shares. A rights offering made to all or substantially all holders of ordinary shares entitling holders to purchase Class A ordinary shares at a price less than the “historical fair market value” (as defined below) will be deemed a share dividend of a number of Class A ordinary shares equal to the product of (i) the number of Class A ordinary shares actually sold in such rights offering (or issuable under any other equity securities sold in such rights offering that are convertible into or exercisable for Class A ordinary shares) and (ii) one minus the quotient of (x) the price per Class A ordinary share paid in such rights offering and (y) the historical fair market value. For these purposes, (i) if the rights offering is for securities convertible into or exercisable for Class A ordinary shares, in determining the price payable for Class A ordinary shares, there will be taken into account any consideration received for such rights, as well as any additional amount payable upon exercise or conversion and (ii) “historical fair market value” means the volume weighted average price of Class A ordinary shares as reported during the 10 trading day period ending on the trading day prior to the first date on which the Class A ordinary shares trade on the applicable exchange or in the applicable market, regular way, without the right to receive such rights.

In addition, if the Company, at any time while the warrants are outstanding and unexpired, pays a dividend or makes a distribution in cash, securities or other assets to all or substantially all of the holders of the Class A ordinary shares on account of such Class A ordinary shares (or other securities into which the warrants are convertible), other than (a) as described above, (b) any cash dividends or cash distributions which, when combined on a per share basis with all other cash dividends and cash distributions paid on the Class A ordinary shares during the 365-day period ending on the date of declaration of such dividend or distribution does not exceed $0.50 (as adjusted to appropriately reflect any other adjustments and excluding cash dividends or cash distributions that resulted in an adjustment to the exercise price or to the number of Class A ordinary shares issuable on exercise of each warrant) but only with respect to the amount of the aggregate cash dividends or cash distributions equal to or less than $0.50 per share, (c) to satisfy the redemption rights of the holders of Class A ordinary shares in connection with a proposed initial Business Combination, (d) to satisfy the redemption rights of the holders of Class A ordinary shares in connection with a shareholder vote to amend the Amended and Restated Memorandum and Articles of Association (A) to modify the substance or timing of the Company’s obligation to provide holders of the Class A ordinary shares the right to have their shares redeemed in connection with the initial Business Combination or to redeem 100% of the public shares if the Company does not complete its initial Business Combination within 18 months from the closing of the Initial Public Offering or (B) with respect to any other provision relating to the rights of holders of the Company’s Class A ordinary shares, or (e) in connection with the redemption of the Company’s public shares upon failure to complete the Company’s initial Business Combination, then the warrant exercise price will be decreased, effective immediately after the effective date of such event, by the amount of cash and/or the fair market value of any securities or other assets paid on each Class A ordinary share in respect of such event.

Whenever the number of Class A ordinary shares purchasable upon the exercise of the warrants is adjusted, as described above, the warrant exercise price will be adjusted by multiplying the warrant exercise price immediately prior to such adjustment by a fraction (x) the numerator of which will be the number of Class A ordinary shares purchasable upon the exercise of the warrants immediately prior to such adjustment and (y) the denominator of which will be the number of Class A ordinary shares so purchasable immediately thereafter.

In addition, if (x) the Company issues additional Class A ordinary shares or equity-linked securities for capital raising purposes in connection with the closing of the initial Business Combination at an issue price or effective issue price of less than $9.20 per ordinary share (with such issue price or effective issue price to be determined in good faith by the Company’s board of directors and, in the case of any such issuance to the Sponsor or its affiliates, without taking into account any founder shares held by the Sponsor or such affiliates, as applicable, prior to such issuance) (the “Newly Issued Price”), (y) the aggregate gross proceeds from such issuances represent more than 60% of the total equity proceeds, and interest thereon, available for the funding of the initial Business Combination on the date of the consummation of the initial Business Combination (net of redemptions), and (z) the volume weighted average trading price of the Class A ordinary shares during the 20 trading day period starting on the trading day prior to the day on which the Company consummates its initial Business Combination (such price, the “Market Value”) is below $9.20 per share, the exercise price of the warrants will be adjusted (to the nearest cent) to be equal to 115% of the higher of the Market Value and the Newly Issued Price, the $18.00 per share redemption trigger price described above under “Redemption of warrants” will be adjusted (to the nearest cent) to be equal to 180% of the higher of the Market Value and the Newly Issued Price.

No fractional warrants will be issued upon separation of the units and only whole warrants will trade. If, upon exercise of the warrants, a holder would be entitled to receive a fractional interest in a share, the Company will, upon exercise, round down to the nearest whole number the number of Class A ordinary shares to be issued to the warrant holder.

The Private Placement Warrants have terms and provisions that are identical to those of the warrants being sold as part of the units in the Company’s Initial Public Offering except that the Private Placement Warrants (including the Class A ordinary shares issuable upon exercise of the Private Placement Warrants) will not be transferable, assignable or salable until 30 days after the completion of the initial Business Combination (except pursuant to limited exceptions to the Company’s officers and directors and other persons or entities affiliated with the initial purchasers of the Private Placement Warrants). The Private Placement Warrants will be redeemable by the Company in all redemption scenarios and exercisable by the holders on the same basis as the warrants included in the units being sold in the Initial Public Offering.

The Company accounts for the 15,900,000 warrants issued in connection with the Initial Public Offering (including 7,666,667 Public Warrants and 8,233,333 Private Placement Warrants ), and will account for the 3,333,334 Forward Purchase Warrants and Backstop Warrants to be issued in connection with the OmniAb Business Combination, in accordance with the guidance contained in ASC 815-40. Such guidance provides that the warrants described above are not precluded from equity classification. Equity-classified contracts are initially measured at fair value (or allocated value). Subsequent changes in fair value are not recognized as long as the contracts continue to be classified in equity.

​

The Forward Purchase and Backstop Securities were fair valued based on the difference between the current fair values of each of the underlying components of the agreement (i.e. the Class A ordinary shares and the warrants) and the present value of the contractual forward prices. As the Backstop Securities only apply in the event of and to the extent that the funds in the Company’s Trust Account falls below $100 million as the result of redemptions, the valuation considered an expected redemption rate based on redemption rates exhibited by similar companies in the market during the third quarter of 2022 and the expected post-redemption Trust Account balance. As the Forward Purchase and Backstop Securities will only apply in the event that the Company completes an initial business combination, the value reflects the probability of completing an initial business combination.

Immediately prior to the Merger (as defined below) and pursuant to a Separation and Distribution Agreement, dated as of March 23, 2022, among the Company, Ligand and Legacy OmniAb (the “Separation Agreement”), Ligand transferred the OmniAb Business, including certain related subsidiaries of Ligand, to Legacy OmniAb and, in connection therewith, distributed (the “Distribution”) to Ligand stockholders 100% of the common stock of Legacy OmniAb, par value $0.001 (the “Legacy OmniAb Common Stock”).  

Immediately following the Distribution, in accordance with and subject to the terms and conditions of the Merger Agreement, Merger Sub merged with and into Legacy OmniAb (the “Merger”), with Legacy OmniAb continuing as the surviving company in the Merger and as a wholly-owned subsidiary of the Company.

The Merger Agreement, along with the Separation Agreement and the other transaction documents to be entered into in connection therewith, provided for, among other things, the consummation of the following transactions (collectively, the “OmniAb Business Combination”): (i) redomiciling by way of continuation from the Cayman Islands to Delaware and domesticating as a Delaware corporation in accordance with Section 388 of the Delaware General Corporation Law and with Section 206 of the Cayman Islands Companies Act (As Revised) at least one business day prior to the closing of the OmniAb Business Combination (the “Domestication”), (ii) Ligand transferred the OmniAb Business (the “Separation”) to its wholly-owned subsidiary Legacy OmniAb, and contributed $15 million in capital thereto (less certain reimbursable transaction and other expenses), and (iii) following the Separation, Ligand distributed 100% of the shares of Legacy OmniAb Common Stock to Ligand stockholders by way of the Distribution. Following the completion of the foregoing transactions and subject to the satisfaction or waiver of certain other conditions set forth in the Merger Agreement, the parties consummated the Merger. The Distribution and Merger are intended to qualify as “tax-free” transactions.

On April 28, 2022, the Company filed a registration statement on Form S-4 (File No. 333-264525) (as amended, the “Form S-4”) with the SEC, which includes the proxy statement/prospectus/information statement that was distributed to holders of the Company’s ordinary shares in connection with the Company’s solicitation for proxies for the vote by the Company’s shareholders in connection with the OmniAb Business Combination and other matters as described in the Form S-4. The Form S-4 has been amended five times, as filed with the SEC on June 13, 2022, July 26, 2022, August 22, 2022, September 13, 2022 and September 27, 2022. The Form S-4 was declared effective by the SEC on September 30, 2022, and the definitive proxy statement/prospectus/information statement was mailed to the Company’s shareholders of record as of the record date for voting on the OmniAb Business Combination. The OmniAb Business Combination closed on November 1, 2022. Upon consummation of the OmniAb Business Combination, and after the Domestication, we have one class of common stock, par value $0.0001 per share, which is listed on Nasdaq under the ticker symbol “OABI”. Our then-outstanding warrants are listed on Nasdaq under the ticker symbol “OABIW”.

The Business Combination was accounted for as a reverse recapitalization in accordance with GAAP, whereby the Company is treated as the acquired company and Legacy OmniAb is treated as the acquirer. Accordingly, for accounting purposes, the Business Combination was treated as the equivalent of Legacy OmniAb issuing stock for the net assets of the Company, accompanied by a recapitalization. The net assets of the Company were stated at historical cost, with no goodwill or other intangible assets recorded. Subsequent presentations of the results of operations presented for the period prior to the Business Combination will be for those of Legacy OmniAb.

Legacy OmniAb has been determined to be the accounting acquirer in the Business Combination based on the following predominate factors:

​

Agreement and Plan of Merger

At the time the OmniAb Business Combination was effected (the “Closing”), each share of Legacy OmniAb Common Stock outstanding after the Distribution and immediately prior to the effective time of the Merger was converted into a number of shares of common stock in the newly formed company (“OmniAb Common Stock”) on a one-for-one basis into shares in the newly formed company. Holders of Legacy OmniAb options, restricted stock units and performance stock units (determined after the Distribution and the division of Ligand equity awards into Ligand equity awards and OmniAb equity awards pursuant to the Employee Matters Agreement) will have their awards converted into equity awards of the Company and adjusted pursuant to the exchange ratio.

In addition, at the Closing, holders of Legacy OmniAb Common Stock and equity awards also received shares of OmniAb Common Stock subject to certain price-based earnout triggers (“Earnout Shares”), with 50% of such earnout shares vesting upon the combined company’s achievement of a post-transaction volume-weighted average price (“VWAP”) of $12.50 per share of OmniAb Common Stock for any 20 trading days over a consecutive 30 trading-day period, and the remainder vesting upon achievement of a post-transaction VWAP of $15 per share of OmniAb Common Stock for any 20 trading days over a consecutive 30 trading-day period, in each case provided such vesting occurs during the five-year period following the Closing.

In connection with the OmniAb Business Combination, upon the Domestication (i) all issued and outstanding Class A ordinary shares and Class B ordinary shares converted automatically, on a one-for-one basis, into shares of OmniAb Common Stock, (ii) all issued and outstanding warrants converted automatically into warrants to acquire shares of OmniAb Common Stock and (iii) all issued and outstanding Units separated and converted automatically into one share of OmniAb Common Stock and one-third of one warrant to purchase OmniAb Common Stock.

Separation and Distribution Agreement

On March 23, 2022, in connection with the execution of the Merger Agreement, we entered into the Separation Agreement with Legacy OmniAb and Ligand, pursuant to which, among other things, (i) Ligand undertook a series of internal reorganization and restructuring transactions to effect the transfer of its (direct or indirect) ownership of the OmniAb Business to Legacy OmniAb in the Separation and (ii) immediately prior to the Merger and after the Separation, Ligand distributed 100% of the outstanding shares of Legacy OmniAb Common Stock to Ligand’s stockholders in the Distribution.
