    Notes to Condensed Consolidated Financial Statements
    (Unaudited)

    1. Organization and Basis of Presentation

    Description of Business

    OmniAb, Inc. (“OmniAb” or the “Company”, formerly known as Avista Public Acquisition Corp. II (“APAC”)) is a biotechnology company that licenses cutting-edge discovery research technology to the pharmaceutical and biotech industries and academic institutions to enable the discovery of next-generation therapeutics. The Company’s technology platform creates and screens diverse antibody repertoires and is designed to quickly identify optimal antibodies and other target-binding proteins for its partners’ drug development efforts. At the heart of the OmniAb platform is something the Company calls Biological Intelligence™, which powers the immune systems of its proprietary, engineered transgenic animals to create optimized antibody candidates for human therapeutics. The Company primarily derives revenue from license fees for technology access, milestones from partnered programs and service revenue from research programs.

    Business Combination

    On November 1, 2022 (the “Closing Date”), the Company, Ligand Pharmaceuticals Incorporated, a Delaware corporation (“Ligand”), OmniAb Operations, Inc., a Delaware corporation and wholly-owned subsidiary of Ligand (“Legacy OmniAb”, formerly known as OmniAb, Inc.), and Orwell Merger Sub Inc., a Delaware corporation and a wholly-owned subsidiary of APAC (“Merger Sub”), consummated the transactions contemplated by the Agreement and Plan of Merger (the “Merger Agreement”), dated as of March 23, 2022 (the “Business Combination”).

    Basis of Presentation

    The Company’s accompanying condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“U.S. GAAP”). Any reference in these notes to applicable guidance is meant to refer to the authoritative U.S. GAAP as included in the Accounting Standards Codification (“ASC”) and Accounting Standards Updates (“ASU”) of the Financial Accounting Standards Board (“FASB”). The financial information for the three and six months ended June 30, 2025 and 2024, is unaudited but includes all normal and recurring adjustments unless indicated otherwise, which the Company considered necessary for fair presentation of its condensed consolidated statements of operations and comprehensive loss. Certain prior period amounts in the condensed consolidated financial statements have been reclassified to conform to the current period presentation.

    The accompanying condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany transactions and accounts within the Company have been eliminated.

    Liquidity and Capital Resources

    The Company expects to continue to incur losses as it invests in research and development activities to improve its technology platform, market and sell its technologies to existing and new partners, add operational, financial and management information systems and personnel to support its operations and incur ongoing costs associated with operating as a public company. The Company’s ability to continue its operations is dependent upon its ability to generate cash flows from operations and potentially obtain additional capital in the future. The Company believes its existing cash, cash equivalents and short-term investments are sufficient to support operations through at least the next 12 months from the date of issuance of these financial statements.

    The accompanying condensed consolidated financial statements have been prepared assuming the Company will continue as a going concern, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business.

    Emerging Growth Company

    OmniAb qualifies as an emerging growth company as defined in Section 2(a) of the Securities Act of 1933, as amended, (“Securities Act”), as modified by the Jumpstart Our Business Startups Act of 2012 (“JOBS Act”).

    8

    Table of Contents
    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. OmniAb 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, OmniAb, 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 OmniAb’s 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 because of the potential differences in accounting standards used.

    2. Summary of Significant Accounting Policies

    Significant Accounting Policies

    The Company’s significant accounting policies are disclosed in its Annual Report on Form 10-K for the year ended December 31, 2024 filed with the SEC and have not materially changed during the six months ended June 30, 2025. The Company believes that the disclosures provided here are adequate to make the information presented not misleading when these unaudited condensed consolidated financial statements are read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K.

    Use of Estimates

    The preparation of these condensed consolidated financial statements in conformity with U.S. GAAP requires the use of estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and the accompanying notes. Actual results may differ from those estimates.

    Cash, Cash Equivalents, and Restricted Cash

    Cash and cash equivalents consist of cash and highly liquid investments with maturities of three months or less when purchased. Cash and cash equivalents generally consist of bank deposits, money market funds as well as U.S. government and agency securities.

    The following table provides a reconciliation of the components of cash, cash equivalents and restricted cash reported in the condensed consolidated balance sheets to the total of the amount presented in the condensed consolidated statements of cash flows:

    (in thousands)June 30, 2025December 31, 2024
    Cash and cash equivalents$18,281 $27,598 
    Restricted cash
    560 560 
    Total cash, cash equivalents and restricted cash presented in the condensed consolidated statements of cash flows
    $18,841 $28,158 

    Restricted cash relates to deposits for the Company’s property leases. The restriction will lapse when the related leases expire.

    Recent Accounting Pronouncements

    From time to time, new accounting pronouncements are issued by the FASB or other standard setting bodies and adopted by the Company as of the specified effective date. Unless otherwise discussed below, the Company believes that the impact of recently issued standards are either not applicable to the Company or will not have a material impact on its consolidated financial statements upon adoption.

    9

    Table of Contents
    The following table provides a brief description of recently issued accounting standards:

    Standard
    Description
    Effective Date
    Effect on the Financial Statements or Other Significant Matters
    ASU 2023-09, Income Taxes (Topic 740) - Improvements to Income Tax DisclosuresThe amendments in this ASU address investor requests for more transparency about income tax information through improvements to tax disclosures primarily related to the rate reconciliation and income taxes paid information. The ASU also includes certain other amendments to improve the effectiveness of income tax disclosures.Effective for the Company for annual periods beginning after December 15, 2024, with early adoption permitted.
    The ASU will be effective for the Company in the income tax disclosure included in its 2025 Annual Report on Form 10-K and will be applied on a prospective basis. The Company does not expect the adoption of ASU 2023-09 to have a material impact on its consolidated financial statements.
    ASU 2024-03, Income Statement (Topic 220) - Expense Disaggregation Disclosures
    The amendments in this ASU require a public business entity to provide disaggregated disclosures, in the notes to the financial statements, of certain categories of expenses that are included in expense line items on the face of the income statement.
    Effective for the Company for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027.
    The Company is currently evaluating the impact of adopting this standard on its consolidated financial statements and disclosures.

    3. Fair Value Measurement

    The Company measures its financial assets and liabilities at fair value, which is defined as the exit price, or the amount that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.

    The Company uses the following three-level valuation hierarchy that maximizes the use of observable inputs and minimizes the use of unobservable inputs to value its financial assets and liabilities:

    •Level 1 — Observable inputs such as unadjusted quoted prices in active markets for identical instruments.
    •Level 2 — Quoted prices for similar instruments in active markets or inputs that are observable for the asset or liability, either directly or indirectly.
    •Level 3 — Significant unobservable inputs based on the Company’s assumptions.

    Financial Instruments Measured on a Recurring Basis

    The carrying amounts reported in the Company’s condensed consolidated balance sheets for accounts receivable, other assets, accounts payable and accrued expenses and other current liabilities approximate fair value due to their relatively short periods to maturity.

    11

    Table of Contents
    Available-for-Sale Securities

    The Company obtains the fair value of its Level 2 available-for-sale securities from third-party pricing services. The pricing services utilize industry standard valuation models whereby all significant inputs, including benchmark yields, reported trades, broker/dealer quotes, issuer spreads, bids, offers, or other market-related data, are observable. The Company validates the prices provided by the third-party pricing services by reviewing their pricing methods and obtaining market values from other pricing sources. The Company did not adjust or override any fair value measurements provided by these pricing services as of December 31, 2024. There were no level 2 available-for-sale securities as of June 30, 2025. The Company has not transferred any investment securities between classification levels.

    Contingent Liabilities

    Contingent liabilities are measured at fair value each reporting period by using a probability weighted income approach.

    A reconciliation of the Level 3 financial instruments as of June 30, 2025 and December 31, 2024 is as follows:

    _____________
    (1)Changes in the fair values of contingent liabilities in connection with the acquisition of Icagen are recognized in “Other operating income, net” in the condensed consolidated statements of operations and in the operating section of the statements of cash flows. Payments of contingent liabilities are disclosed in the financing section of the statements of cash flows.
    (2)Changes in the fair values of contingent liabilities in connection with the acquisition of Taurus are recognized in “Intangible assets, net” in the condensed consolidated balance sheets. Payments of contingent liabilities are disclosed in the investing section of the statement of cash flows.

    Contingent liabilities are classified as Level 3 liabilities as their valuation requires substantial judgment and estimation of factors that are not currently observable in the market. These subjective estimates include but are not limited to assumptions involving the achievement probability of certain developmental and commercialization milestones, discount rates, and projected years of payments. If different assumptions were used for the various inputs to the valuation approaches, the estimated fair value could be materially higher or lower than the fair value determined.

    4. Short-Term Investments

    The Company classified short-term investments as available-for-sale securities, as the sale of such investments may be required prior to maturity to implement management strategies. The following tables summarize short-term investments as of June 30, 2025 and December 31, 2024:

    The Company had certain available-for-sale debt securities in an unrealized loss position without an allowance for credit loss as of June 30, 2025. Unrealized losses on these debt securities have not been recognized into income because (1) the issuers have high credit quality, (2) management does not intend to sell and it is likely that management will not be required to sell these securities prior to their anticipated recovery and (3) the decline in fair value is largely due to market conditions and/or changes in interest rates. The issuers continue to make timely interest payments on the securities, and the fair value is expected to recover as the bonds approach maturity.

    Goodwill

    There were no changes in the carrying amount of goodwill during the three and six months ended June 30, 2025 and 2024.

    Intangible Assets

    Amortization of finite-lived intangible assets is computed using the straight-line method over the estimated useful life of the asset of up to 20 years and is reflected within “Amortization of intangibles” in the condensed consolidated statements of operations. Amortization expense of $3.2 million and $6.5 million was recognized during the three and six months ended June 30, 2025 respectively. Amortization expense of $4.5 million and $8.0 million was recognized during the three and six months ended June 30, 2024, respectively.

    For each of the three and six months ended June 30, 2025, there was no impairment of finite-lived intangible assets. During the three and six months ended June 30, 2024, the Company determined that certain of its finite-lived intangible assets related to the acquisition of Ab Initio in July 2019 were fully impaired, and recorded a $1.2 million write-off of the net carrying value, which is recorded as “Amortization of intangibles” in the condensed consolidated statements of operations.

    The remaining weighted-average useful life of finite-lived intangible assets is 10.6 years. At June 30, 2025, future amortization expense on intangible assets is estimated to be as follows (in thousands):

    Gain on Sale of Ion Channel Asset

    On May 7, 2025, the Company entered into an Asset Purchase and Assignment Agreement (the “Asset Purchase Agreement”) with Angelini Pharma S.p.A. (“Angelini”). Under the Asset Purchase Agreement, the Company sold, transferred, assigned and conveyed to Angelini, and Angelini purchased, acquired and accepted from the Company, all of the Company’s rights, title and interest in and to the transferred assets, which include among other things the intellectual property and related know-how (collectively, the “Purchased Assets”) generated in connection with the license agreement, dated December 4, 2018, as amended on June 30, 2021, October 21, 2022, and December 22, 2023, by and between F. Hoffmann-La Roche Ltd (“Roche”) and the Company’s subsidiary Icagen, which allowed the Company to receive potential development and commercial milestones and royalties on net sales of any approved products.

    The sale qualified as a sale of a non-financial asset and the carrying value of the Purchased Assets as of May 7, 2025 was zero. Cash proceeds from the sale of $3.0 million were recorded to other operating income, net during the three months ended June 30, 2025, and included as a part of income from operations in accordance with ASC 610-20, Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets.

    7. Commitments and Contingencies

    Lease Commitments

    The Company’s corporate headquarters are located in Emeryville, California and its research facilities are located in Emeryville and Dixon, California, Durham, North Carolina and Tucson, Arizona. It leases approximately 70,000 square feet of space under leases expiring from 2026 to 2032.

    Legal Proceedings

    From time to time, the Company has been and may be involved in various legal proceedings arising in its ordinary course of business. In the opinion of management, resolution of any pending claims (either individually or in the aggregate) is not expected to have a material adverse impact on the condensed consolidated financial statements, cash flows or financial position and it is not possible to provide an estimated amount of any such loss. However, the outcome of disputes is inherently uncertain. Therefore, although management considers the likelihood of such an outcome to be remote, an unfavorable resolution of one or more matters could materially affect future results of operations or cash flows, or both, in a particular period.

    8. Stockholders' Equity

    Authorized and Outstanding Capital Stock

    The total number of shares of the Company’s authorized capital stock is 1,100,000,000. The total amount of authorized capital stock consists of 1,000,000,000 shares of common stock and 100,000,000 shares of preferred stock. As of June 30, 2025, no shares of preferred stock are issued or outstanding.

    Common Stock

    Holders of the Company’s common stock are entitled to one vote for each share held on all matters submitted to a vote of stockholders, including the election of directors, and do not have cumulative voting rights. Subject to preferences that may be applicable to any then outstanding preferred stock, holders of common stock are entitled to receive ratably those dividends, if any, as may be declared by the board of directors out of legally available funds. In the event of the Company’s liquidation, dissolution or winding up, the holders of common stock will be entitled to share ratably in the assets legally available for distribution to stockholders after the payment of or provision for all of the Company's debts and other liabilities, subject to the prior rights of any preferred stock then outstanding. Holders of common stock have no preemptive or conversion rights or other subscription rights and there are no redemption or sinking fund provisions applicable to the common stock. All outstanding shares of common stock are duly authorized, validly issued, fully paid and nonassessable. The rights, preferences and privileges of holders of common stock are subject to and may be adversely affected by the rights of the holders of shares of any series of preferred stock that the Company may designate and issue in the future.

    Preferred Stock

    Under the terms of the Company’s certificate of incorporation, its board of directors has the authority, without further action by the Company's stockholders, to issue up to 100,000,000 shares of preferred stock in one or more series, to establish from time to time the number of shares to be included in each such series, to fix the dividend, voting and other rights, preferences and privileges of the shares of each wholly unissued series and any qualifications, limitations or restrictions thereon, and to increase or decrease the number of shares of any such series, but not below the number of shares of such series then outstanding.

    17

    Table of Contents
    The Company’s board of directors may authorize the issuance of preferred stock with voting or conversion rights that could adversely affect the voting power or other rights of the holders of common stock. The issuance of preferred stock, while providing flexibility in connection with possible acquisitions and other corporate purposes, could, among other things, have the effect of delaying, deterring or preventing a change in the Company’s control and may adversely affect the market price of the common stock and the voting and other rights of the holders of common stock. The Company has no current plans to issue any shares of preferred stock.

    Earnout Shares

    Some of the Company’s shares of common stock are subject to certain price-based earnout triggers (the “Earnout Shares”). Earnout Shares vest based upon the achievement of certain volume-weighted average trading prices (“VWAP”) for shares of the Company for any 20 trading days over a consecutive 30 trading-day period during the five-year period following the Closing Date, with (i) 50% of such Earnout Shares vesting upon achievement of a VWAP of $12.50 per share of common stock or upon the occurrence of a change of control transaction that will result in the holders of common stock receiving a price per share in excess of $12.50, and (ii) the remaining 50% of the Earnout Shares vesting upon achievement of a VWAP of $15.00 per share of common stock or upon the occurrence of a change of control transaction that will result in the holders of common stock receiving a price per share in excess of $15.00. The Earnout Shares are not transferable until the vesting condition for the applicable tranche of Earnout Shares has been achieved. Prior to vesting, holders of Earnout Shares are entitled to exercise the voting rights carried by such shares and receive any dividends or other distributions in respect of such shares. As of June 30, 2025, 14,999,243 Earnout Shares were issued and outstanding.

    Pursuant to the Sponsor Insider Letter Agreement executed concurrently with the Merger Agreement, by and among APAC, Avista Acquisition LP II (the “Sponsor”), Legacy OmniAb and certain insiders of APAC, 1,293,299 shares of OmniAb common stock held by the Sponsor became subject to the same price-based vesting conditions as the Earnout Shares (the “Sponsor Earnout Shares”). The Sponsor Earnout Shares are accounted for as equity-classified equity instruments and recorded in additional paid-in capital as part of the Business Combination. As of June 30, 2025, 1,293,299 Sponsor Earnout Shares were issued and outstanding.

    The Earnout Shares and Sponsor Earnout Shares will be automatically forfeited for no consideration if an applicable triggering event has not occurred from the Closing Date to and including the fifth anniversary of the Closing Date.

    Public, Private Placement, Forward Purchase and Backstop Warrants

    The Company assumed 7,666,667 warrants originally issued in APAC’s initial public offering (the “Public Warrants”) and 8,233,333 warrants issued in a private placement that closed concurrently with APAC’s initial public offering, (the “Private Placement Warrants”) in the Business Combination. Additionally, pursuant to the Amended and Restated Forward Purchase Agreement, dated as of March 23, 2022 (the “A&R FPA”), on the Closing Date, the Company issued 1,666,667 warrants in the Forward Purchase (the “Forward Purchase Warrants”) and 1,445,489 warrants in the Redemption Backstop (the “Backstop Warrants”). The Public, Private Placement, Forward Purchase and Backstop Warrants entitle the holder to purchase one share of the Company’s common stock at an exercise price of $11.50 per share.

    The Public Warrants are publicly traded and are exercisable for cash unless certain conditions occur, such as the failure to have an effective registration statement related to the shares issuable upon exercise or redemption by the Company under certain conditions, at which time the warrants may be cashless exercised at the option of the Company.

    The Public Warrants are only exercisable for a whole number of shares of common stock. No fractional shares are to be issued upon exercise of the warrants. The Public Warrants will expire on November 1, 2027 (which is five years after the completion of the Business Combination), at 5:00 p.m., New York City time, or earlier upon redemption or liquidation. The Public Warrants are listed on the Nasdaq Capital Market under the symbol “OABIW”.

    Additionally, the Company can redeem the outstanding Public Warrants:

    •in whole and not in part;
    •at a price of $0.01 per warrant;
    •upon not less than 30 days’ prior written notice of redemption to each warrant holder; and
    18

    Table of Contents
    •if, and only if, the closing price of the common stock equals or exceeds $18.00 per share (as adjusted for share subdivisions, share capitalizations, reorganizations, recapitalizations and the like) for any 20 trading days within a 30-trading day period ending three trading days before the Company sends the notice of redemption to the warrant holders provided there was an effective registration statement covering the shares of common stock issuable upon exercise of the warrants.

    If the Company calls the Public Warrants for redemption as previously described, the Company has the option to require all holders that wish to exercise the Public Warrants to do so on a cashless basis.

    The Private Placement Warrants have terms and provisions that are identical to the Public Warrants except that the Private Placement Warrants were not transferable, assignable or salable until 30 days after the completion of the Business Combination. 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 Public Warrants. The Forward Purchase Warrants and the Backstop Warrants have the same terms as the Private Placement Warrants.

    The Company evaluated the Public, Private Placement, Forward Purchase and Backstop Warrants under ASC 815-40, Derivatives and Hedging-Contracts in Entity’s Own Equity (“ASC 815-40”), and concluded they meet the criteria for equity classification as they are considered to be indexed to the Company’s own stock. Upon consummation of the Business Combination, the Public, Private Placement, Forward Purchase and Backstop Warrants were recorded in additional paid-in capital.

    Equity Compensation Plans

    2022 Incentive Award Plan

    The Company’s board of directors and stockholders adopted the 2022 Incentive Award Plan (the “2022 Plan”), which became effective upon the Closing of the Business Combination. Under the 2022 Plan, the Company may grant cash and equity incentive awards to eligible employees, directors and consultants.

    As of June 30, 2025, the aggregate number of shares of our common stock that may be issued under the 2022 Plan is 36,319,977 shares. In addition, the number of shares of our common stock available for issuance under the 2022 Plan will be annually increased on January 1 of each calendar year beginning in 2023 and ending in 2032 by an amount equal to the lesser of (i) a number equal to 5% of the fully-diluted shares on the final day of the immediately preceding calendar year or (ii) such smaller number of shares as is determined by the Company's board of directors.

    The 2022 Plan provides for the grant of stock options, including incentive stock options and nonqualified stock options, stock appreciation rights, restricted stock, dividend equivalents, restricted stock units (“RSUs”) and other stock or cash-based awards.

    OmniAb Prior Plans

    In connection with the Business Combination, Legacy OmniAb adopted the OmniAb, Inc. 2022 Ligand Service Provider Assumed Award Plan and the OmniAb, Inc. 2022 OmniAb Service Provider Assumed Award Plan (collectively, the “OmniAb Prior Plans”), which govern the OmniAb equity awards issued upon adjustment of outstanding Ligand equity awards in connection with Ligand’s distribution of Legacy OmniAb common stock to Ligand stockholders. All awards under the OmniAb Prior Plans that were outstanding as of the closing of the Business Combination continued to be governed by the terms, conditions and procedures set forth in the OmniAb Prior Plans and any applicable award agreements, as those terms may be equitably adjusted in connection with the Business Combination. The Company assumed the OmniAb Prior Plans in connection with the closing of the Business Combination, and each of the awards thereunder.

    At the Market Offering

    In December 2023, the Company entered into an Open Market Sale AgreementSM (the “Sales Agreement”), with Jefferies LLC (the “Sales Agent”) under which it may, from time to time, sell shares of its common stock having an aggregate offering price of up to $100.0 million in “at the market” (“ATM”) offerings through the Sales Agent. Sales of the shares of common stock, if any, will be made at prevailing market prices at the time of sale, or as otherwise agreed with the Sales Agent. The Sales Agent will receive a commission from the Company of up to 3.0% of the gross proceeds of any shares of common stock sold under the Sales Agreement. Sales of its common stock made pursuant to the Sales Agreement are made under its shelf registration statement on Form S‐3 which was filed on December 8, 2023 and declared effective by the SEC on December 18,

    2023. The Company is not obligated to sell, and the Sales Agent is not obligated to buy or sell, any shares of common stock under the Sales Agreement. During the year ended December 31, 2024, 2,771,192 shares of common stock in the ATM offering were issued for net proceeds of $11.4 million, after deducting commissions. No shares of common stock in the ATM offering were issued during the six months ended June 30, 2025.

    Total share-based compensation expense$4,111 $5,383 $8,255 $11,078 

    Stock Options

    Stock options granted under the 2022 Plan typically vest 1/8 on the six-month anniversary of the date of grant, and 1/48 each month thereafter for 42 months. All option awards generally expire 10 years from the date of grant.

    The Company uses the Black-Scholes option-pricing model to estimate the fair value of stock options granted. The model assumptions include expected volatility, expected term, dividend yield, and the risk-free interest rate.

    •Expected volatility: Due to the Company’s limited trading history for its common stock, the Company lacks sufficient historical data to support its expected stock price volatility. As such, the Company utilized a weighted approach by blending its own limited historical data with the volatilities of publicly traded biotechnology peers. The Company will continue to apply this approach until it has enough historical data to solely support its expected volatility.
    •Expected term: The expected term represents the period of time that options are expected to be outstanding. Because the Company has limited historical exercise behavior, it determines the expected life assumption using the simplified method which is an average of the contractual term of the option and its vesting period.
    •Dividend yield: The Company bases the expected dividend yield assumption on the fact that it has never paid cash dividends and has no present intention to pay cash dividends and, therefore, used an expected dividend yield of zero.
    •Risk-free interest rate: The risk-free interest rate is based upon U.S. Treasury securities with remaining terms similar to the expected term of the share-based awards.

    The fair value of each option issued was estimated on the grant date using the Black-Scholes option pricing model with the following weighted-average assumptions:

    (1)The aggregate intrinsic value is calculated as the difference between the exercise price of the underlying options and the estimated fair value of the common stock for in the money options as of June 30, 2025.

    As of June 30, 2025, unrecognized share-based compensation expense related to OmniAb options was $21.5 million, which is expected to be recognized over a remaining weighted-average period of approximately 1.27 years. As of June 30, 2025, unrecognized share-based compensation expense related to Ligand options was $0.1 million, which is expected to be recognized over a remaining weighted-average period of approximately 0.20 years.

    The aggregate intrinsic value of OmniAb options exercised by OmniAb service providers during the six months ended June 30, 2025 was negligible. Cash received from OmniAb options exercised by OmniAb service providers during the six months ended June 30, 2025 was negligible.

    There were no OmniAb options exercised by Ligand employees during the six months ended June 30, 2025.

    Restricted Stock Units

    RSUs generally represent the right to receive a certain number of shares of common stock subject to certain vesting conditions and other restrictions. RSUs generally vest over three years. The fair value of RSUs is determined by the closing market price on the grant date.

    The following table summarizes RSU activity during the six months ended June 30, 2025 under the Company’s equity awards plans:

    The aggregate intrinsic value of OmniAb RSUs vested for OmniAb service providers during the six months ended June 30, 2025 was $2.0 million.

    Performance Restricted Stock Units

    Performance restricted stock units (“PRSUs”) generally represent the right to receive a certain number of shares of common stock based on the achievement of certain corporate performance or market goals and continued employment during the vesting period.

    The Company’s PRSUs contain a market condition dependent upon the Company’s relative and absolute total stockholder return over a three-year period, with a payout range of 0% to 200% of the target shares granted. Share-based compensation expense for these PRSUs is measured using the Monte-Carlo valuation model and is not adjusted for the achievement, or lack thereof, of the market conditions.

    During the six months ended June 30, 2025, the PRSUs were achieved at a 158% achievement level.

    The following table summarizes the PRSU activity during the six months ended June 30, 2025, under the Company’s equity awards plans:

    Employee Stock Purchase Plan

    Under the Company’s 2022 Employee Stock Purchase Plan (the “ESPP”), eligible employees are entitled to purchase shares of common stock at a discount with accumulated payroll deductions. The ESPP provides for a series of overlapping 24-month offering periods comprising four six-month purchase periods. The purchase price for shares of common stock purchased under the ESPP is equal to 85% of the lesser of the fair market value of the Company’s common stock on (i) the first trading day of the applicable offering period or (ii) the last trading day of each six month purchase period in the applicable offering period.

    As of June 30, 2025, the aggregate number of shares of the Company’s common stock that may be issued pursuant to rights granted under the ESPP equals 3,768,385 shares of the Company’s common stock. In addition, on the first day of each calendar year beginning on January 1, 2023 and ending on (and including) January 1, 2032, the number of shares available for issuance under the ESPP will be increased by a number of shares equal to the lesser of (i) 1% of the fully diluted shares outstanding on the final day of the immediately preceding calendar year, and (ii) such smaller number of shares as determined by the Company’s board of directors.

    As of June 30, 2025, there was $0.8 million of unrecognized share-based compensation expense associated with the ESPP, which is expected to be recognized over a remaining weighted-average period of 1.31 years.

    During the six months ended June 30, 2025, there were 274,625 shares issued pursuant to the ESPP.

    10. Income Taxes

    The Company’s effective tax rate may vary from the U.S. federal statutory tax rate due to the valuation allowance placed on deferred tax assets, change in the mix of earnings in various state jurisdictions with different statutory rates, benefits related to tax credits, and the tax impact of non-deductible expenses, stock award activities and other permanent differences between income before income taxes and taxable income. The Company’s effective tax rate for the three and six months ended June 30, 2025 was (0.8)% and 0.0%, respectively. The variance from the U.S. federal statutory tax rate of 21.0% for each of the three and six months ended June 30, 2025 was primarily due to the valuation allowance established on federal and state attributes and the tax impact of stock award activities that was partially offset with the benefit related to research and development tax credits. The Company’s effective tax rate for each of the three and six months ended June 30, 2024 was 12.2%. The variance from the U.S. federal statutory tax rate of 21.0% for each of the three and six months ended June 30, 2024 was primarily due to the valuation allowance established on federal and state attributes and the tax impact of stock award activities that was partially offset with the benefit related to research and development tax credits.

    The Company considered the realizability of the deferred tax assets and recorded a valuation allowance as necessary for the amount of deferred tax assets which are not more likely than not to be realized as of June 30, 2025.

    11. Net Loss Per Share

    Loss Per Share

    Basic loss per share is calculated by dividing net loss by the weighted-average number of common shares outstanding during the period. Diluted loss per share is computed based on the sum of the weighted average number of common shares and dilutive common shares outstanding during the period. As described in Note 8 – Stockholders' Equity, Earnout Shares issued in connection with the Business Combination are subject to vesting based on the VWAP of common shares during the earnout period. The Earnout Shares are excluded from the calculation of basic and diluted weighted-average number of common shares outstanding until vested.

    The following table outlines the basic and diluted net loss per share for the three and six months ended June 30, 2025 and 2024:

    Overview

    OmniAb licenses cutting-edge discovery research technology to pharmaceutical and biotech companies and academic institutions to enable the discovery of next-generation therapeutics. Our technology platform creates and screens diverse antibody repertoires and is designed to quickly identify optimal antibodies and other target-binding proteins for our partners’ drug development efforts. At the heart of the OmniAb platform is what we call Biological Intelligence™, which powers the immune systems of our proprietary, engineered transgenic animals to create optimized antibody candidates for human therapeutics.

    We believe the OmniAb animals comprise the most diverse host systems available in the industry. Our suite of technologies and methods, including computational antigen design and immunization methods, paired with high-throughput single B cell phenotypic screening and mining of next-generation sequencing datasets with custom algorithms, are used to identify fully human antibodies with exceptional performance and developability characteristics. We provide our partners both integrated end-to-end capabilities and highly customizable offerings, which address critical industry challenges and provide optimized discovery solutions.

    As of June 30, 2025, we had 100 active partners with 381 active programs using the OmniAb technology platform, including 28 OmniAb-derived antibodies in clinical development by our partners, one under regulatory review, and three approved products developed and commercialized by our partners.
    25

    Table of Contents

    Our proprietary technologies are joined with and leverage a suite of in silico, artificial intelligence and machine learning tools for therapeutic discovery and optimization that are woven throughout our various technologies and capabilities. Additionally, an established core competency focused on ion channels and transporters further differentiates OmniAb’s technology and creates opportunities in many important and emerging target classes. OmniAb technologies are designed to be leveraged for the discovery of a variety of next-generation antibody-based therapeutic modalities, including bi- and multi-specific biologics, antibody-drug conjugates, CAR-T therapies, targeted radiotherapeutics, and many others.

    The OmniAb suite of technologies spans from Biological Intelligence-powered repertoire generation to cutting-edge antibody discovery and optimization offering an increasingly efficient and customizable end-to-end solution for the growing discovery needs of the global pharmaceutical industry.

    We partner with pharmaceutical and biotechnology companies and leading academic institutions that vary in size, clinical stage, geography and therapeutic focus. Our partners gain access to wide repertoires of antibodies and state-of-the-art screening technologies designed to enable efficient discovery of next-generation novel therapeutics and deliver high-quality therapeutic antibody candidates for a wide range of diseases. Our partners can select a biological target to treat a disease and define the antibody properties needed for therapeutic development or use certain of our technologies directly in their own laboratories.

    Our license agreements with pharmaceutical and biotechnology partners generally include: (i) upfront or, in some instances, annual payments for technology access; (ii) payments for performance of research services; (iii) downstream payments in the form of preclinical, intellectual property, clinical, regulatory, and commercial milestones; and (iv) royalties on net sales of our partners’ products, if any. License agreements with academic institutions are typically structured with revenue sharing. We succeed when our partners are successful, and our agreements are structured to align economic and scientific interests. Our license agreements typically include reporting requirements, which provide us updates from our partners on the status of their programs. In addition, we track our active partnered programs by reviewing our partners’ public announcements and maintaining close communications with our partners to the extent possible. In some instances, a partner may not publicly announce milestones, in which case, we would be generally dependent on our partner to track, report and disclose to us milestones at the time of achievement. Our license agreements typically grant a perpetual license to our technology and are typically terminable by our partners without penalty with specified notice. However, all milestone payments and royalties survive termination and continue with respect to any OmniAb-derived antibodies. The royalty term is generally the longer of 10 years from the first commercial sale or through the last expiration in any jurisdiction of the patents covering such OmniAb-derived antibody. Importantly, our royalty term is typically linked to the patents that our partners file related to the antibody discovered using our technology, which both lengthens and diversifies the royalty streams we receive. Our typical royalty rates for antibody discovery contracts are currently in the low- to mid-single digits and can vary depending on other economic terms in the agreement. Although our license agreements with pharmaceutical and biotechnology partners typically include technology access fees, milestone payments and royalties, each agreement is negotiated separately and as a result, the financial terms and contractual provisions vary from agreement to agreement. By providing a full suite of antibody discovery technologies with streamlined economics, we believe we offer an attractive option to industry stakeholders.

    We believe the long-term value of our business will be driven by royalties given that such payments are based on global sales of potential future partner programs, which generally provide for larger and recurring payments as compared to technology access, research and milestone payments. We believe our revenue will be materially driven by milestones in the shorter term, and by royalties in the longer term, from our partnered programs. However, there is significant uncertainty in timing and likelihood of reaching marketing authorization in drug discovery and development, and we cannot be certain when, if at all, royalty payments will be a material portion of our revenue. Furthermore, we do not control the progression, clinical development, regulatory strategy or eventual commercialization of programs discovered using our platform, and as a result, we are dependent on our partners’ efforts and decisions with respect to such programs.


    Key Business Metrics

    We regularly review the following key business metrics to evaluate our business, measure our performance, identify trends affecting our business, formulate financial projections and make strategic decisions. We believe that the following metrics are important to understanding our current business. These metrics are highly dependent on information provided by our partners and may change or may be substituted for additional or different metrics as our business continues to grow.

    Active partners represents the number of partners that have rights to an active program or have executed a license agreement in advance of initiating an active program. A partner is removed from the metric when the partner informs us they are terminating their license or they are no longer in business. We view this metric as an indication of the competitiveness of our platform and our current level of market penetration. The metric also relates to our opportunities to secure additional active programs.

    Active programs represents a program for which research work has commenced or where an antigen is introduced into our animals and remains so as long as the program is actively being developed or commercialized. This number includes active clinical programs and approved products separately disclosed in the table above. We view this metric as an indication of the usage of our technology and the potential for mid- and long-term milestone and royalty payments.

    Active clinical programs and approved products represents the number of unique programs for which an Investigational New Drug Application (“IND”) or equivalent under other regulatory regimes has been filed based on an OmniAb-derived antibody and which are in clinical development by our partners. We continue to count programs as active as long as they are actively being developed, under regulatory review or commercialized. Where the date of such application is not known to us, we use the official start date from clinical trial registries for the purpose of calculating this metric. This number includes approved products separately disclosed in the table above. We view this metric as an indication of our near- and mid-term potential revenue from milestone fees and potential royalty payments in the long term.

    Approved products represents an OmniAb-derived antibody for which our partner has received marketing approval. We view this metric as an indication of our near- and mid-term potential revenue from royalty payments.

    Our business metrics are subject to risk and uncertainties related to our dependence on our partners providing timely and accurate information, which impacts our ability to objectively and accurately characterize the current level of activity for each program. In addition, changes in our key business metrics do not directly correlate to current revenues. For more information, see the section in our 2024 Annual Report titled “Risk Factors - Our management uses certain key business metrics to evaluate our business, measure our performance, identify trends affecting our business, formulate financial projections and make strategic decisions, and such metrics may not accurately reflect all of the aspects of our business needed to make such evaluations and decisions, in particular as our business continues to grow.”

    Liquidity and Capital Resources
    As of June 30, 2025, our cash, cash equivalents and short-term investments were $41.6 million. We believe our existing cash, cash equivalents and short-term investments are sufficient to support operations through at least the next 12 months from the date of issuance of these financial statements.

    If our anticipated cash flows from operations and current cash are insufficient to satisfy our liquidity requirements because of increased expenditures or lower demand for our technology platform, or the realization of other risks, we may be required to raise additional capital through issuances of public or private equity or debt financing or other capital sources. Such additional financing may not be available on terms acceptable to us or at all. In any event, we may consider raising additional capital in the future to expand our business, to pursue strategic investments or acquisitions, to take advantage of favorable market conditions or financing opportunities or for other reasons. Our future capital requirements will depend on many factors, including, but not limited to:

    •our ability to achieve revenue growth, which is dependent on the ability of our partners to successfully develop and commercialize therapies based on antibodies discovered using our platform;
    •the costs of expanding our operations, including our business development and marketing efforts;
    •our rate of progress in selling access to our platform and marketing activities associated therewith;
    •our rate of progress in, and cost of research and development activities associated with, our platform technologies and our internal developed programs to the extent we pursue any such programs;
    •the effect of competing technological and market developments;
    •the impact of pandemic or epidemic diseases on global social, political and economic conditions;
    •the costs involved in preparing, filing, prosecuting, maintaining, defending and enforcing patents and other intellectual property and proprietary rights; and
    •the costs associated with any technologies that we may in-license or acquire.

    In December 2023, we entered into an Open Market Sale AgreementSM (the “Sales Agreement”), with Jefferies LLC (the “Sales Agent”) under which we may, from time to time, sell shares of our common stock having an aggregate offering price of up to $100.0 million in an “at the market” (“ATM”) offerings program through the Sales Agent. Sales of the shares of common stock, if any, will be made at prevailing market prices at the time of sale, or as otherwise agreed with the Sales Agent. The Sales Agent will receive a commission from us of up to 3.0% of the gross proceeds of any shares of common stock sold under the Sales Agreement. Sales of our common stock made pursuant to the Sales Agreement are made under our shelf registration statement on Form S‐3 which was filed on December 8, 2023 and declared effective by the SEC on December 18, 2023. We are not obligated to sell, and the Sales Agent is not obligated to buy or sell, any shares of common stock under the Sales Agreement. As of June 30, 2025, $88.3 million remains available under the Sales Agreement for future sales of our common stock.

    We anticipate that our principal uses of cash in the future will be primarily to fund our operations, working capital needs, capital expenditures and other general corporate purposes.

    Additionally, we may receive up to $218.6 million from the exercise of our warrants, assuming the exercise in full of all the warrants for cash, but not from the sale of the shares of our common stock issuable upon such exercise. As of the date of this report, our warrants are “out of the money,” which means that the trading price of the shares of our common stock underlying our warrants is below the $11.50 exercise price of the warrants. For so long as the warrants remain out of the money, we do not expect warrant holders to exercise their warrants. Therefore, any cash proceeds that we may receive in relation to the exercise of such securities will be dependent on the trading price of our common stock.

    Critical Accounting Policies and Estimates

    There have been no material changes to our critical accounting policies and estimates during the six months ended June 30, 2025, as compared to the critical accounting policies and estimates disclosed in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” included in the 2024 Annual Report.

    Recent Accounting Pronouncements

    For the summary of recent accounting pronouncements, see Note 2 – Summary of Significant Accounting Policies to our financial statements included in this Quarterly Report.

    Item 3. Quantitative and Qualitative Disclosures about Market Risk

    As of June 30, 2025, there were no material changes to our market risks from the discussion provided in Item 7A of our 2024 Annual Report.

    Item 4. Controls and Procedures

    Conclusion Regarding the Effectiveness of Disclosure Controls and Procedures

    We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our periodic and current reports that we file with the SEC is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable and not absolute assurance of
    32

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

    Our management, with the participation of our principal executive officer and principal financial officer, has evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of June 30, 2025, the end of the period covered by this Quarterly Report. Based upon such evaluation, our principal executive officer and principal financial officer have concluded that our disclosure controls and procedures were effective at the reasonable assurance level as of such date.

    Changes in Internal Control Over Financial Reporting

    There have been no changes in our internal control over financial reporting during the last fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

    Part II – Other Information

    Item 1. Legal Proceedings

    For information that updates the disclosures set forth under Part I, Item 3, “Legal Proceedings” in our 2024 Annual Report, refer to Note 7 – Commitments and Contingencies to the condensed consolidated financial statements contained in Part I, Item 1, of this report.

    From time to time, we may be subject to legal proceedings. We are not currently a party to or aware of any proceedings that we believe will have, individually or in the aggregate, a material adverse effect on our business, financial condition or results of operations. However, regardless of outcome, litigation can have an adverse impact on our business because of defense and settlement costs, diversion of management resources and other factors, and there can be no assurances that favorable outcomes will be obtained.

    Item 1A. Risk Factors

    The risk factors described in our 2024 Annual Report are not the only risks we face. Factors we currently do not know, factors that we currently consider immaterial or factors that are not specific to us, such as general economic conditions, may also materially adversely affect our business or our consolidated operating results, financial condition or cash flows. We do not believe that there have been any material changes to the risk factors disclosed in Part I, Item 1A of our 2024 Annual Report, except for the following:

    Recent government healthcare reform and other legislative measures could adversely affect our business and results of operations.

    The Trump administration has issued executive orders that address the pricing of pharmaceuticals in the United States and proposed a so-called most favored nation pricing policy, which would tie the price of drugs in the United States to the lowest price in a group of other countries. While it is unclear whether and how the Trump proposals will be implemented, the Trump policies are likely to have a negative impact on the pharmaceutical industry. Even proposals or executive actions that are ultimately deemed unlawful could negatively impact the U.S. pharmaceutical sector and our business.

    Some states are seeking to implement general, across the board price caps for pharmaceuticals, or are seeking to regulate drug distribution. Changing reimbursement and pricing actions in various states have negatively affected, and may continue to negatively affect, pharmaceutical products. State legislative measures could limit the price or payment for certain drugs or could complicate the distribution of drugs.

    In addition, the One Big Beautiful Bill Act, which was enacted in July 2025, imposes significant reductions in the funding of the Medicaid program. Such reductions are expected to decrease the number of persons enrolled in Medicaid and reduce the services covered by Medicaid, which could adversely affect our partners’ sales of their products and any other product candidates that they may commercialize.

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

    None.

    Item 3. Defaults Upon Senior Securities

    None.

    Item 4. Mine Safety Disclosures

    Not applicable.

    Item 5. Other Information

    Rule 10b5-1 Trading Arrangements

    34

    Table of Contents
    From time to time, our officers (as defined in Rule 16a-1(f) of the Exchange Act) and directors may enter into Rule 10b5-1 or non-Rule 10b5-1 trading arrangements (as each such term is defined in Item 408 of Regulation S-K). During the three months ended June 30, 2025, none of our officers or directors adopted, modified, or terminated any such trading arrangements.
