1. Organization and Basis of Presentation

Separation and Business Combination

On November 1, 2022 (the “Closing Date”), OmniAb, Inc. (“OmniAb” or the “Company,” formerly known as Avista Public Acquisition Corp. II (“APAC”)), Ligand Pharmaceuticals Incorporated, a Delaware corporation (“Ligand” or the “Parent”), OmniAb Operations, Inc., a Delaware corporation and wholly-owned subsidiary of Ligand (“Legacy OmniAb”, formerly known as OmniAb, Inc. and, together with Ligand, collectively, the “Companies”), 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.

In connection with, and as contemplated by, the Merger Agreement, on November 1, 2022, in accordance with the terms of the Separation and Distribution Agreement, dated as of March 23, 2022, by and among APAC, Ligand and Legacy OmniAb (the “Separation Agreement”), Ligand transferred the Legacy OmniAb business, including certain related subsidiaries of Ligand, to Legacy OmniAb and made a contribution to the capital of Legacy OmniAb of $1.8 million, after deducting certain transaction and other expenses reimbursable by Legacy OmniAb (the “Separation”). Following the Separation, as contemplated by the Separation Agreement, Ligand distributed on a pro rata basis to its stockholders all of the shares of common stock, par value $0.001 per share, of Legacy OmniAb (“Legacy OmniAb Common Stock”) held by Ligand, such that each holder of shares of common stock, par value $0.001 per share, of Ligand (“Ligand Common Stock”) was entitled to receive one share of Legacy OmniAb Common Stock for each share of Ligand Common Stock held by such holder as of the record date for the distribution, October 26, 2022 (the “Distribution”).

Following the Separation and Distribution, on November 1, 2022, Merger Sub merged with and into Legacy OmniAb, with Legacy OmniAb surviving as a direct, wholly owned subsidiary of OmniAb (the “Business Combination”). See Note 4 – Business Combination, for further details.

The Business Combination was accounted for as a reverse recapitalization in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). Under this method of accounting, APAC was treated as the acquired company and Legacy OmniAb was treated as the acquirer for financial reporting purposes. Accordingly, for accounting purposes, the reverse recapitalization was treated as the equivalent of Legacy OmniAb issuing stock for the net assets of APAC, accompanied by a recapitalization. The consolidated and combined assets, liabilities and results of operations prior to the Business Combination are those of Legacy OmniAb, and the assets, liabilities and results of operations of APAC were consolidated with Legacy OmniAb beginning on the Closing Date. The net assets of APAC are stated at historical cost, with no goodwill or other intangible assets recorded.

Legacy OmniAb was determined to be the accounting acquirer based on the following predominant factors:

•Legacy OmniAb’s existing stockholders have the greatest voting interest in the Company with approximately 85% of the voting interest;
•Legacy OmniAb nominated a majority of the initial members of the Company’s board of directors;
•Legacy OmniAb’s senior management is the senior management of the Company;
•Legacy OmniAb is the larger entity based on historical operating activity and has the larger employee base; and
•The post-combination company assumed a Legacy OmniAb branded name: “OmniAb, Inc.”

Basis of Presentation

The Company’s accompanying condensed consolidated and combined financial statements have been prepared in accordance with 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 (“ASUs”) of the Financial Accounting Standards Board (“FASB”). Certain prior period amounts in the condensed consolidated and combined financial statements have been reclassified to conform to the current period presentation.

7


Periods prior to Separation

The accompanying combined financial statements for periods prior to the Separation have been prepared on a stand-alone basis and are derived from Ligand’s consolidated financial statement accounting records. The operations comprising Legacy OmniAb were in various legal entities wholly owned by Ligand. Accordingly, Ligand’s net investment in these operations is shown in lieu of stockholder’s equity in the combined financial statements.

Legacy OmniAb comprised certain stand-alone legal entities for which discrete financial information was available. As Ligand recorded transactions at the legal entity level, allocation methodologies were applied to certain accounts to allocate amounts to Legacy OmniAb, as discussed further below.

Legacy OmniAb entities were under the common control of Ligand as a result of, among other factors, Ligand’s ownership. As the entities were under common control, the financial statements report the financial position, results of operations and cash flows of Legacy OmniAb as though the transfer of net assets and equity interests had occurred as of January 2016. Transactions between Ligand and Legacy OmniAb were accounted through Parent company net investment in Legacy OmniAb. The total net effect of the settlement of these intercompany transactions is reflected in Legacy OmniAb’s combined balance sheets as Parent company net investment in Legacy OmniAb. All significant intercompany transactions with Ligand are deemed to have been paid in the period the costs were incurred. Expenses related to corporate allocations from Ligand to Legacy OmniAb were considered to be effectively settled for cash in the combined financial statements at the time the transaction was recorded.

The combined financial statements include all revenues, expenses, assets and liabilities directly associated with the business activity of Legacy OmniAb as well as an allocation of certain general and administrative expenses related to facilities, functions and services provided by Ligand. These corporate expenses have been allocated to Legacy OmniAb based on direct usage or benefit, where identifiable, with the remainder allocated based on headcount or a percentage of total operating expenses or other measures that management believes are consistent and reasonable. See Note 3 – Relationship with Parent and Related Entities.

Ligand maintains various share-based compensation plans at a corporate level. Legacy OmniAb employees participated in those programs, and a portion of the compensation cost associated with those plans are included in Legacy OmniAb’s combined statements of operations and Parent company net investment. The amounts presented in the combined financial statements are not necessarily indicative of future awards and may not reflect the results that Legacy OmniAb would have experienced as a stand-alone entity. See Note 3 – Relationship with Parent and Related Entities for additional discussion.

All of the allocations and estimates in the combined financial statements are based on assumptions that management believes are reasonable. However, the combined financial statements included herein may not be indicative of the financial position, results of operations and cash flows of Legacy OmniAb in the future or if Legacy OmniAb had been a separate, stand-alone publicly traded entity during the periods presented.

Periods after the Separation

Following the Separation, the Company began accounting for its financial activities as an independent entity. The Company’s financial statements as of December 31, 2022 and March 31, 2023 and for the three months ended March 31, 2023 are based on the reported results of OmniAb as a standalone company. The accompanying 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.

Separation-related adjustments

Pursuant to the Separation Agreement, certain accounts receivable, accounts payable, and accrued liabilities included in Legacy OmniAb’s combined balance sheets immediately prior to the Separation were retained by Ligand, and therefore, were adjusted through net parent investment in Legacy OmniAb’s combined financial statements. In addition, in connection with the Separation, certain equity awards were converted in accordance with the Employee Matters Agreement, as further described in Note 11 – Share-Based Compensation.

As a standalone entity, the Company will file tax returns on its own behalf, and tax balances and the effective income tax rate may differ from the amounts reported in the historical periods. The difference between the tax attributes the Company historically calculated on a carve-out basis and the actual tax attributes that the Company received as a standalone entity on
8


November 1, 2022 was adjusted through additional paid-in-capital. As of November 1, 2022 and in connection with the Separation, the Company adjusted its deferred tax balances and computed its related tax provision to reflect operations as a standalone entity.

Liquidity and Capital Resources

Prior to the Separation, Legacy OmniAb was dependent upon Ligand for all of its working capital and financing requirements, as Ligand used a centralized approach to cash management and financing its operations. There were no cash amounts specifically attributable to Legacy OmniAb for the historical periods presented; therefore, there was no cash reflected in the combined financial statements. Accordingly, cash and cash equivalents, debt or related interest expense were not allocated to Legacy OmniAb in the combined financial statements. Financing transactions related to OmniAb were accounted for as a component of the Parent company net investment in the combined balance sheets and as a financing activity including an interest expense component allocation on the accompanying combined statements of cash flows.

In connection with the Separation, Ligand funded the Company with approximately $1.8 million of cash. Additionally, the Company’s proceeds, net of transactions costs from the Business Combination were $95.8 million. See Note 4 – Business Combination, for further details.

For the three months ended March 31, 2023 and 2022, the Company’s revenue was $16.9 million and $9.6 million, respectively. For the three months ended March 31, 2023 and 2022, the Company’s net loss was $6.1 million and $6.3 million, respectively. The Company expects to continue to incur losses as it invests in research and development activities to improve its technology and 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 additional 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 marketable securities and the cash it expects to generate from operations will provide it the flexibility needed to meet operating, investing, and financing needs and support operations through at least the next 12 months.

The accompanying condensed consolidated and combined 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”).

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

Use of Estimates

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

9


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. As of March 31, 2023, cash and cash equivalents consisted of bank deposits, money market funds as well as U.S. government agency and corporate debt securities. The following table provides a reconciliation of the components of cash, cash equivalents and restricted cash reported in the condensed consolidated and combined balance sheets to the total of the amount presented in the condensed consolidated and combined statements of cash flows:

(in thousands)March 31, 2023December 31, 2022
Cash and cash equivalents$22,906 $33,390 
Restricted cash included in other non-current assets404 449 
Total cash, cash equivalents and restricted cash presented in the condensed consolidated and combined statements of cash flows$23,310 $33,839 

The restricted cash relates to the Company’s property leases and is included in “Other long-term assets”. The restriction will lapse when the related leases expire.

Short-term Investments

Short-term investments primarily consist of commercial paper, corporate debt securities, asset-backed securities and government and agency securities. The Company classifies short-term investments as “available-for-sale” as the sale of such investments may be required prior to maturity to implement management strategies. Therefore, the Company has classified all investments with original maturity dates beyond three months as current assets in the accompanying condensed consolidated and combined balance sheets. Any premium or discount arising at purchase is amortized and/or accreted to interest income as an adjustment to yield using the straight-line method over the life of the instrument. Investments are reported at their estimated fair value. Unrealized gains and losses are included in accumulated other comprehensive income as a component of stockholders’ equity until realized.

Accounts Receivable

Accounts receivable represents the amounts billed to the Company’s partners and that are due unconditionally for services it has performed. The Company establishes an allowance for credit losses to present the net amount of accounts receivable expected to be collected. The allowance requires an estimation based upon historical loss experienced and adjusted for factors that are relevant to determining the expected collectability of accounts receivable. Some of these factors include historical loss experience, delinquency trends, aging behavior of receivables, credit and liquidity quality indicators for industry groups, customer classes or individual customers and the current and expected future economic and market conditions.

Property and Equipment

Property and equipment are stated at cost, subject to review for impairment, and depreciated over the estimated useful lives of the assets using the straight-line method. Amortization of leasehold improvements is recorded over the shorter of the lease term or estimated useful life of the related asset. Maintenance and repairs are charged to operations as incurred. When assets are sold, or otherwise disposed of, the cost and related accumulated depreciation are removed from the accounts and any gain or loss is included in operating income or expense.

AssetEstimated Useful Life
Lab and office equipment
4 - 7 years
Computer hardware
3 - 5 years
Leasehold improvementsShorter of the useful life or remaining lease term
Computer software
Shorter of 3 years or useful life of asset

10


Acquisitions

The Company first determines whether a set of assets acquired constitutes a business and should be accounted for as a business combination. If the assets acquired are not a business, the Company accounts for the transaction as an asset acquisition. Business combinations are accounted for by using the acquisition method of accounting which requires the Company to use significant estimates and assumptions, including fair value estimates, as of the business combination date and to refine those estimates as necessary during the measurement period (defined as the period, not to exceed one year, in which the Company may adjust the provisional amounts recognized).

Under the acquisition method of accounting, the Company recognizes separately from goodwill the identifiable assets acquired, the liabilities assumed, including contingent consideration and all contractual contingencies, generally at the acquisition date fair value. Contingent purchase consideration to be settled in cash is remeasured to estimated fair value at each reporting period with the change in fair value recorded in the statement of operations. Costs that the Company incurs to complete the business combination such as investment banking, legal and other professional fees are not considered part of consideration and the Company charges them to general and administrative expense as they are incurred.

The Company measures goodwill as of the acquisition date as the excess of consideration transferred, which is also measured at fair value, over the net of the acquisition date amounts of the identifiable assets acquired and liabilities assumed.

Should the initial accounting for a business combination be incomplete by the end of a reporting period that falls within the measurement period, the Company reports provisional amounts in its financial statements. During the measurement period, the Company adjusts the provisional amounts recognized at the acquisition date to reflect new information obtained about facts and circumstances that existed as of the acquisition date that, if known, would have affected the measurement of the amounts recognized as of that date and the Company records those adjustments to its financial statements in the period of change, if any.

Under the acquisition method of accounting for business combinations, if the Company identifies changes to acquired deferred tax asset valuation allowances or liabilities related to uncertain tax positions during the measurement period and they relate to new information obtained about facts and circumstances that existed as of the acquisition date, those changes are considered a measurement period adjustment and the Company records the offset to goodwill. The Company records all other changes to deferred tax asset valuation allowances and liabilities related to uncertain tax positions in current period income tax expense.

Goodwill, Intangible Assets and Other Long-Lived Assets

Goodwill, which has an indefinite useful life, represents the excess of cost over fair value of net assets acquired. Goodwill is reviewed for impairment at least annually during the fourth quarter, or more frequently if an event occurs indicating the potential for impairment. During the goodwill impairment review, the Company assesses qualitative factors to determine whether it is more-likely-than-not that the fair value of its reporting unit is less than the carrying amount, including goodwill. The Company operates in one reporting unit. The qualitative factors include, but are not limited to, macroeconomic conditions, industry and market considerations, cost factors, the overall financial performance, and events affecting the reporting unit. If, after assessing the totality of these qualitative factors, the Company determines that it is not more-likely-than-not that the fair value of its reporting unit is less than the carrying amount, then no additional assessment is deemed necessary. Otherwise, the Company proceeds to perform the quantitative assessment. The Company will then evaluate goodwill for impairment by comparing the estimated fair value of the reporting unit to its carrying value, including the associated goodwill. To determine the fair value, the Company generally uses a combination of market approach based on OmniAb and comparable publicly traded companies in similar lines of businesses and the income approach based on estimated discounted future cash flows. The Company’s cash flow assumptions consider historical and forecasted revenue, operating costs and other relevant factors. The Company may also elect to bypass the qualitative assessment in a period and elect to proceed to perform the quantitative assessment for the goodwill impairment test. The Company performed the annual assessment for goodwill impairment during the fourth quarter of 2022, noting no impairment indicators under the qualitative assessment.

The Company’s identifiable intangible assets are composed of acquired core technologies, licensed technologies, contractual relationships, customer relationships and trade names. Identifiable intangible assets with finite lives are generally amortized on a straight-line basis over the assets’ respective estimated useful lives. The Company regularly performs reviews to determine if any event has occurred that may indicate that intangible assets with finite useful lives and other long-lived assets are potentially impaired. If indicators of impairment exist, an impairment test is performed to assess the recoverability of the affected assets by determining whether the carrying amount of such assets exceeds the undiscounted expected future cash flows. If the affected assets are not recoverable, the Company estimates the fair value of the assets and records an impairment loss if
11


the carrying value of the assets exceeds the fair value. Factors that may indicate potential impairment include market conditions, industry and economic trends, changes in regulations, clinical success, historical and forecasted financial results, significant changes in the ability of a particular asset to generate positive cash flows, and the pattern of utilization of a particular asset. The Company did not identify indicators of impairment for the finite-lived intangibles and other long-lived assets at March 31, 2023 and December 31, 2022.

Public, Private Placement, Forward Purchase and Backstop Common Stock 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, as further discussed in Note 4 – Business Combination, 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 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. Since the Public, Private Placement, Forward Purchase and Backstop Warrants met the criteria for equity classification upon the consummation of the Business Combination, the Company recorded these warrants in additional paid-in capital as part of the Business Combination.

Revenue Recognition

The Company’s revenue is primarily generated from license fees for technology access, development, regulatory and sales based milestone payments, service revenue for performance of research, and royalties on product sales. The Company applies the following five-step model in accordance with ASC 606, Revenue from Contracts with Customers, in order to determine revenue: (i) identification of the promised goods or services in the contract; (ii) determination of whether the promised goods or services are performance obligations, including whether they are distinct in the context of the contract; (iii) measurement of the transaction price, including the constraint on variable consideration; (iv) allocation of the transaction price to the performance obligations; and (v) recognition of revenue when (or as) the Company satisfies each performance obligation.

The Company’s revenue is typically derived from license agreements with its partners and consists of: (i) upfront or annual payments for technology access (license revenue) and payments for performance of research services (service revenue); (ii) downstream payments in the form of preclinical, intellectual property, clinical, regulatory, and commercial milestones (milestone revenue) and (iii) royalties on net sales from partners’ product sales, if any.

License fees are generally recognized at a point in time once the Company grants partners access to intellectual property rights. The Company generally satisfies its obligation to grant intellectual property rights on the effective date of the contract.

The Company recognizes service revenue for contracted R&D services performed for partners over time. The Company measures its progress using an input method based on the effort it expends or costs it incurs toward the satisfaction of its performance obligation. The Company estimates the amount of effort it expends, including the time it will take to complete the activities, or the costs it may incur in a given period, relative to the estimated total effort or costs to satisfy the performance obligation. This results in a percentage that it multiplies by the transaction price to determine the amount of revenue recognized each period. This approach requires the Company to make estimates and use judgment. If estimates or judgments change over the course of the collaboration, they may affect the timing and amount of revenue recognized in current and future periods.

12


The Company includes contingent milestone based payments in the estimated transaction price when there is a basis to reasonably estimate the amount of the payment and it is probable of being achieved. These estimates are based on historical experience, anticipated results and its best judgment at the time. If the contingent milestone based payment is sales-based, we apply the royalty recognition constraint and record revenue when the underlying sale has taken place. Significant judgments must be made in determining the transaction price for licenses of intellectual property. Because of the risk that products in development with partners will not reach development based milestones or receive regulatory approval, the Company generally recognizes any contingent payments that would be due to it upon or after achievement of the development milestone or regulatory approval.

Deferred Revenue

Depending on the terms of the arrangement, the Company may also defer a portion of the consideration received if it had to satisfy a future obligation.

The timing of revenue recognition, billings and cash collections results in billed accounts receivable, unbilled receivables (contract assets), and customer advances and deposits (contract liabilities) on the condensed consolidated and combined balance sheets. The Company generally receives payment at the point it satisfies its obligation or soon after. Any fees billed in advance of being earned are recorded as deferred revenue. During the three months ended March 31, 2023, the amount recognized as revenue that was previously deferred at December 31, 2022 was $3.1 million. During the three months ended March 31, 2022, the amount recognized as revenue that was previously deferred at December 31, 2021 was $3.4 million.

Disaggregation of Revenue

The disaggregated revenue categories are presented on the face of the condensed consolidated and combined statements of operations and comprehensive loss.

Research and Development Expenses

Research and development expenses consist of material, equipment, facilities and labor costs of scientific staff who are working pursuant to collaborative agreements and other research and development projects. Also included in research and development expenses are third-party costs incurred for research programs including in-licensing costs, and costs incurred by other research and development service vendors. The Company expenses these costs as they are incurred. When the Company makes payments for research and development services prior to the services being rendered, it records those amounts as prepaid assets on its condensed consolidated and combined balance sheets and it expenses them as the services are provided.

Share-Based Compensation

Prior to the Separation, certain Company employees, directors, managers and advisors participated in share-based compensation plans sponsored by Ligand. Ligand share-based compensation awards consisted of stock options, restricted stock units (“RSUs”), performance restricted stock units (“PRSUs”) and other cash-based or share-based awards. As such, prior to the Separation the awards granted to Company employees, directors, managers and advisors are reflected in Parent company net investment within the combined statements of stockholders’ equity at the time they were expensed. Prior to the Separation, the condensed consolidated and combined statements of operations and comprehensive loss also include an allocation of Ligand’s corporate and shared employee share-based compensation expenses.

The Company recognizes share-based compensation expense based on the estimated fair value on a straight-line basis over the requisite service periods of the awards, taking into consideration forfeitures as they occur. The fair value of RSUs is determined by the closing market price of the Company’s common stock on the date of grant. PRSUs generally represent the right to receive a certain number of shares of common stock based on the achievement of the Company’s corporate performance goals and continued employment during the vesting period. 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.

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

The Company measures and recognizes compensation expense for shares to be issued under its employee stock purchase plan based on an estimated grant date fair value recognized on a straight-line basis over the offering period.

Income Taxes

The Company provides for income taxes under the asset and liability method prescribed by the ASC Topic 740, Income Taxes (“Topic 740”). Deferred tax assets and liabilities are determined based on differences between financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates in effect when the differences are expected to reverse. If necessary, deferred tax assets are reduced by a valuation allowance to reflect the uncertainty associated with their ultimate realization.

The Company accounts for uncertain tax positions recognized in the condensed consolidated and combined financial statements in accordance with the provisions of Topic 740 by prescribing a more-likely-than-not threshold for financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. When uncertain tax positions exist, we recognize the tax benefit of tax positions to the extent that the benefit will more likely than not be realized. The determination as to whether the tax benefit will more likely than not be realized is based upon the technical merits of the tax position as well as consideration of the available facts and circumstances. The Company evaluates uncertain tax positions on a quarterly basis and adjusts the level of the liability to reflect any subsequent changes in the relevant facts surrounding the uncertain positions. Any changes to these estimates, based on the actual results obtained and/or a change in assumptions, could affect its income tax provision in future periods. Interest and penalty charges, if any, related to unrecognized tax benefits would be classified as a provision for income tax in its condensed consolidated and combined statements of operations.

Prior to the Separation, Legacy OmniAb’s income taxes include current and deferred income taxes of Ligand allocated to its combined financial statements in a manner that is systematic, rational and consistent with the asset and liability method prescribed in Topic 740. Accordingly, the Company’s income tax provision was prepared following the “Separate Return Method.” The Separate Return Method applies Topic 740 to the combined financial statements of the OmniAb members of the consolidated group as if the group member were a separate taxpayer which joined in filing a consolidated federal income tax return and combined state income tax returns separate from Ligand.

In general, the taxable income or loss of Legacy OmniAb for the tax periods prior to November 1, 2022 were included in Ligand’s U.S. consolidated federal and combined state income tax returns, where applicable. As such, separate income tax returns were not prepared for OmniAb. Consequently, income taxes currently payable are deemed to have been remitted by Ligand in the period the liability arose and income taxes currently receivable were deemed to have been received from Ligand in the period that a refund could have been recognized by OmniAb had the Company been a separate taxpayer, if applicable. For the tax periods after October 31, 2022, the Company will file its own consolidated federal income tax return and combined state income tax returns separate from Ligand. Any income taxes due for the tax periods after October 31, 2022 will be directly payable by the Company.

Income (Loss) Per Share

Basic income (loss) per share is calculated by dividing net income (loss) by the weighted-average number of common shares outstanding during the period. Diluted income (loss) per share is computed based on the sum of the weighted average number of common shares and potentially dilutive common shares outstanding during the period.

For periods prior to the Separation, basic and diluted income (loss) per share was calculated based on the 82.6 million shares issued to Ligand shareholders at the Closing Date.

Comprehensive Income (Loss)

Comprehensive income (loss) represents net income (loss) adjusted for the change during the periods presented in unrealized gains and losses on available-for-sale debt securities and reclassification adjustments for realized gains or losses included in net income (loss). The unrealized gains or losses are reported in the condensed consolidated and combined statements of operations and comprehensive income (loss).

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. The Company has evaluated recently issued accounting pronouncements and
14


concluded that they are either not applicable to the business, or that no material effect is expected on the condensed consolidated and combined financial statements as a result of future adoption.

Segment Information

Operating segments are components of an enterprise for which separate financial information is available and is evaluated regularly by the Company’s chief operating decision-maker in deciding how to allocate resources and assess performance. The Company currently operates in one reportable business segment.


3. Relationship with Parent and Related Entities

Prior to the Separation, the OmniAb business was managed and operated in the normal course of business consistent with other affiliates of the Parent. Accordingly, certain shared costs were allocated to the Company and reflected as expenses in the combined financial statements. Management considered the allocation methodologies used to be reasonable and appropriate reflections of the historical Parent expenses attributable to OmniAb for purposes of the stand-alone financial statements. However, the expenses reflected in the combined financial statements may not be indicative of the actual expenses that would have been incurred during the periods presented if OmniAb historically operated as a separate, stand-alone entity. In addition, the expenses reflected in the combined financial statements may not be indicative of related expenses that will be incurred in the future by OmniAb.

General Corporate Overhead

The combined statements of operations include expenses for certain centralized functions (such as information systems, accounting, treasury, audit, purchasing, human resources, legal and facilities), executive compensation and other programs provided and/or administered by Parent that were charged directly to the Company. A portion of these costs benefited the Company and were allocated using a pro-rata method based on project-related costs or other measures that management believed were consistent and reasonable.

Costs of $1.8 million for the three months ended March 31, 2022 have been reflected in the general and administrative expenses in our combined statements of operations for our allocated share of Parent’s corporate overhead.

Cash Management and Financing

The Company participated in Ligand’s centralized cash management and financing programs prior to the Separation.

Disbursements were made through centralized accounts payable systems which were operated by Ligand. Cash receipts were transferred to centralized accounts, also maintained by Ligand. As cash was disbursed and received by Ligand, it was accounted for through the Parent company net investment. All obligations were financed by Ligand and financing decisions were determined by central Ligand treasury operations.

Equity-Based Incentive Plans

Certain of our employees participated in the former Parent’s equity-based incentive plans. Under the Ligand 2002 Stock Incentive Plan (the “2002 Plan”), employees, directors, managers and advisors were awarded share-based incentive awards in a number of forms, including nonqualified stock options. Under the 2002 Plan, employees could be awarded share-based incentive awards which included non-statutory stock options or incentive stock options, restricted stock units, performance stock units and other cash-based or share-based awards. Awards granted to employees under the incentive plans typically vested 1/8 on the six-month anniversary of the date of grant, and 1/48 each month thereafter for forty-two months. The Company measured share-based compensation for all share-based incentive awards at fair value on the grant date. Share-based compensation expense was generally recognized on a straight-line basis over the requisite service periods of the awards.

Compensation costs associated with the Company’s employees’ participation in the incentive plans were specifically identified for employees who exclusively supported the Company’s operations and were allocated to the Company as part of the cost allocations from the Company’s former Parent. Total costs charged to the Company related to its employees’ participation in the former Parent’s incentive plans, depending on the nature of the employee’s role in our operations, were $3.1 million ($1.9 million in research and development expenses and $1.2 million in general and administrative expenses) during the three months ended March 31, 2022.

Employee Stock Purchase Plan

The Company’s eligible employees participated in its former Parent’s ESPP. The ESPP permitted eligible participants to purchase Ligand’s shares at a discount through regular payroll deductions of up to 10% of their eligible compensation during the offering period. The ESPP was typically implemented through consecutive six-month offering periods. The purchase price of the shares was 85% of the lesser of the fair market value of the closing price per share on the first day of the offering period and the fair market value of the closing price per share on the last day of the offering period.

4. Business Combination

As discussed in Note 1 – Organization and Basis of Presentation, on November 1, 2022, the Company consummated the transactions contemplated by the Merger Agreement. At the Closing Date, and subject to the terms and conditions of the Merger Agreement, each outstanding share of Legacy OmniAb Common Stock was cancelled in exchange for 4.90007 shares of common stock of OmniAb, par value $0.0001 per share (“OmniAb Common Stock”) and 0.75842 shares of OmniAb Common Stock subject to certain price-based earnout triggers (the “Earnout Shares”). Holders of shares of Legacy OmniAb Common Stock received an aggregate 82,611,789 shares of the OmniAb Common Stock, excluding Earnout Shares, as consideration in the Business Combination.

In addition, all outstanding Legacy OmniAb equity awards were converted into OmniAb equity awards to purchase, in the case of options, or receive, in the case of restricted stock units and performance-vesting restricted stock units, shares of OmniAb Common Stock, in each case, equal to the number of shares underlying such Legacy OmniAb equity awards multiplied by the Exchange Ratio. Each holder of an outstanding Legacy OmniAb equity award also received Earnout Shares equal to the number of shares of Legacy OmniAb Common Stock underlying such equity award multiplied by 0.75842.

Holders of shares of Legacy OmniAb Common Stock and holders of Legacy OmniAb equity awards received an aggregate 14,999,243 Earnout Shares as consideration in the Business Combination. Fifty percent of the Earnout Shares will vest on the date on which the volume-weighted average price (“VWAP”) equals or exceeds $12.50 on any 20 trading days in any 30 consecutive trading-day period, and all remaining Earnout Shares will vest on the date on which the VWAP equals or exceeds $15.00 on any 20 trading days in any 30 consecutive trading-day period, in each case provided such vesting occurs during the five year period following the Closing Date (the “Earnout Period”); provided, that in the event of a Change of Control (as defined in the Merger Agreement) during the Earnout Period pursuant to which OmniAb or any of its stockholders have the right to receive, directly or indirectly, cash, securities or other property attributing a value of at least $12.50 (with respect to 50% of the Earnout Shares) or $15.00 (with respect to all Earnout Shares) per share of OmniAb Common Stock, and such Change of Control has been approved by a majority of the independent directors of the OmniAb board of directors, then such Earnout Shares shall be deemed to have vested immediately prior to such Change of Control. The Earnout Shares are accounted for as equity-classified equity instruments and recorded in additional paid-in capital as part of the Business Combination.

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 “Earnout Founder Shares”). The Earnout Founder Shares are accounted for as equity-classified equity instruments and recorded in additional paid-in capital as part of the Business Combination.

On the Closing Date, the Company completed the issuance and sale of 1,500,000 shares of the Company’s common stock and 1,666,667 Forward Purchase Warrants to the Sponsor for an aggregate purchase price of $15.0 million (the “Forward Purchase”), pursuant to the amended and restated forward purchase agreement (the “A&R FPA”). Additionally, and also pursuant to the A&R FPA, on the Closing Date, the Company completed the sale of 8,672,934 shares of the Company’s common stock and 1,445,489 Backstop Warrants to the Sponsor for a purchase price of $10.00 per share and aggregate purchase price of $86.7 million in order to backstop shareholder redemptions which would have otherwise resulted in the cash proceeds available to OmniAb following the Business Combination from OmniAb’s trust account to be less than $100,000,000. Refer to Note 10 – Stockholders' Equity, for additional information on the accounting for the Forward Purchase Warrants and Backstop Warrants.

The Business Combination was accounted for as a reverse recapitalization in accordance with U.S. GAAP. Under this method of accounting, APAC was treated as the “acquired” company and OmniAb is treated as the acquirer for financial reporting purposes. Accordingly, for accounting purposes, the Business Combination was treated as the equivalent of OmniAb
16


issuing stock for the net assets of APAC, accompanied by a recapitalization. The net assets of APAC are stated at historical cost, with no goodwill or other intangible assets recorded.

Upon the closing of the Business Combination, the Company’s certificate of incorporation was amended and restated to, among other things, increase the total number of authorized shares of all classes of capital stock to 1,100,000,000 shares, $0.0001 par value per share, of which, 1,000,000,000 shares are designated as OmniAb Common Stock and 100,000,000 shares are designated as preferred stock.

5. 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 following tables provide a summary of the assets and liabilities that are measured at fair value on a recurring basis as of March 31, 2023 and December 31, 2022:

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

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 March 31, 2023 or December 31, 2022. 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.

_____________
(1)Changes in the fair values of contingent liabilities in connection with the acquisition of Icagen are recognized in Other operating (income) expense, net in the condensed consolidated and combined statements of operations and comprehensive loss and in the operating section of the statements of cash flows. Payments to CVR holders 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 and xCella are recognized in Intangible assets, net in the condensed consolidated and combined balance sheets. Payments to CVR holders 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.

Assets Measured on a Non-Recurring Basis

The Company applies fair value techniques on a non-recurring basis associated with valuing potential impairment losses related to goodwill, finite-lived intangible assets, and long-lived assets.


6. 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 March 31, 2023 and December 31, 2022:

The Company had certain available-for-sale debt securities in an unrealized loss position without an allowance for credit loss as of March 31, 2023. Unrealized losses on these debt securities have not been recognized into income for the following reasons: (1) risk of default is low due to the high credit quality of the issuers, (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 months ended March 31, 2023 and 2022.

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 depreciation and amortization expense on the condensed consolidated and combined statements of operations and comprehensive loss. Amortization expense of $3.4 million was recognized for each of the three months ended March 31, 2023 and 2022. For each of the three months ended March 31, 2023 and 2022, there was no impairment of intangible assets with finite lives.

The remaining weighted-average useful life of definite lived intangible assets is 12.7 years. At March 31, 2023, future amortization expense on intangible assets is estimated to be as follows (in thousands):

9. Commitments and Contingencies

Lease Commitments

The Company’s corporate headquarters and research and development facilities are located in Emeryville, California, where it leases approximately 35,000 square feet of space under leases expiring in 2032. The Company’s ion technology business leases approximately 31,000 square feet of research and development space in Durham, North Carolina and Tucson, Arizona, under leases that expire between 2026 and 2029.

The below tables provide supplemental cash flow and other information related to operating leases (in thousands, except for lease term and discount rate):

In addition to base rent, certain of the Company’s operating leases require variable payments. These variable lease costs include amounts relating to common area maintenance and are expensed when the obligation for those payments is incurred and are recognized as operating expenses in the condensed consolidated and combined statements of operations. The following table summarizes the components of operating lease expense for the three months ended March 31, 2023 and 2022:

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 and combined 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.

10. 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 March 31, 2023, no shares of preferred stock are issued or outstanding.

Common Stock

Holders of OmniAb 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 OmniAb Common Stock are entitled to receive ratably those dividends, if any, as may be declared by the Company’s board of directors out of legally available funds. In the event of liquidation, dissolution or winding up, the holders of OmniAb 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 OmniAb Common Stock have no preemptive or conversion rights or other subscription rights and there are no redemption or sinking fund provisions applicable to the OmniAb 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 OmniAb 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.

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 OmniAb Common Stock. The issuance of preferred stock, while providing flexibility in connection with possible acquisitions and other corporate purposes, could, among other things,
23


have the effect of delaying, deterring or preventing a change in the Company’s control and may adversely affect the market price of OmniAb Common Stock and the voting and other rights of the holders of OmniAb Common Stock. The Company has no current plans to issue any shares of preferred stock.

Earnout Shares

As of March 31, 2023, OmniAb Earnout Shares of 14,999,243 and Sponsor Earnout Shares of 1,293,299 are issued and outstanding. 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 OmniAb Common Stock or upon the occurrence of a change of control transaction that will result in the holders of OmniAb 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 New OmniAb common stock or upon the occurrence of a change of control transaction that will result in the holders of New OmniAb 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.

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

Warrants

As part of APAC’s initial public offering, 7,666,667 Public Warrants were sold. The Public Warrants entitle the holder thereof to purchase one share of common stock at a price of $11.50 per share, subject to adjustments. 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, once the Public Warrants become exercisable, 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
•if, and only if, the closing price of the ordinary shares 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.

Simultaneously with APAC’s initial public offering, APAC consummated a private placement of 8,233,333 Private Placement Warrants with APAC’s sponsor. Each Private Placement Warrant is exercisable for one share of common stock at a price of $11.50 per share, subject to adjustment. The Private Placement Warrants have terms and provisions that are identical to those of 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.

Additionally, on the Closing Date, the Company issued 1,666,667 Forward Purchase Warrants and 1,445,489 Backstop Warrants pursuant to the A&R FPA. The Forward Purchase Warrants and Backstop Warrants have the same terms as the Private Placement Warrants.

The Company concluded the Public, Private Placement, Forward Purchase and Backstop Warrants meet the criteria to be classified as equity. 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

24


2022 Incentive Award Plan

The Company’s board of directors and stockholders adopted the 2022 Incentive Award Plan, or 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 March 31, 2023, the aggregate number of shares of our common stock that may be issued under the 2022 Plan is 22,447,321 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, 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 referred to as the OmniAb Prior Plans, which govern the OmniAb Equity Awards issued upon adjustment of outstanding Ligand equity awards in connection with the Distribution. 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 time of the Distribution, and after giving effect to the adjustment of the OmniAb Equity Awards to reflect the Business Combination, awards representing the right to receive an aggregate of 5,997,765 and 8,302,710 shares of the Company's common stock were outstanding under the OmniAb, Inc. 2022 Ligand Service Provider Assumed Award Plan and the OmniAb, Inc. 2022 OmniAb Service Provider Assumed Award Plan, respectively. No future awards will be granted under the OmniAb Prior Plans. Shares subject to outstanding awards under the OmniAb Prior Plans as of the effective date of the 2022 Plan may, on or following the effective date of the 2022 Plan, become available for issuance pursuant to the 2022 Plan recycling provisions.


11. Share-Based Compensation

Conversion and Modification of Equity Awards Outstanding at Separation Date

In connection with the Separation on November 1, 2022, under the provisions of the existing plans, the Company adjusted its outstanding equity awards in accordance with the Merger Agreement to preserve the intrinsic value of the awards immediately before and after the Distribution. Upon the Distribution, employees holding stock options, restricted stock units and performance restricted stock units denominated in pre-Distribution Ligand stock received a number of otherwise-similar awards either in post-Distribution Ligand stock or in a combination of post-Distribution Ligand stock and OmniAb stock based on conversion ratios outlined for each group of employees in the Merger Agreement that the Company entered into in connection with the Distribution. The equity awards that were granted prior to March 2, 2022 were converted under the shareholder method, wherein employees holding outstanding equity awards received equity awards in both Ligand and OmniAb. For equity awards granted after March 2, 2022, for Ligand employees, the number of awards that were outstanding at the Separation were proportionately adjusted into post-Distribution Ligand stock to maintain the aggregate intrinsic value of the awards at the date of the Separation; for OmniAb employees, the number of awards that were outstanding at the Separation were proportionately adjusted into post-Distribution OmniAb stock to maintain the aggregate intrinsic value of the awards at the date of the Separation. The conversion ratio was determined based on the relative values of Ligand common stock in the “regular way” and “ex-distribution” markets during the five-trading day period prior to the closing of the Business Combination.

These modified awards otherwise retained substantially the same terms and conditions, including term and vesting provisions. Due to the modification of the equity awards as a result of the Distribution, the Company compared the fair value of
25


the outstanding equity awards immediately before and after the Distribution. Due to the immaterial amount of incremental expense, the Company did not recognize any incremental fair value as a result of the modification.

The Company will not incur any future compensation cost related to equity awards held by Ligand employees and directors. The Company will incur future compensation cost related to Ligand equity awards held by OmniAb employees.

The Company recognized share-based compensation expense by function as follows:

Three Months Ended March 31,

Performance restricted stock units151 456 
Total share-based compensation expense$6,055 $3,146 

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, term, dividends, and the risk-free interest rate.

•Expected volatility: Since the Company is a newly public company and does not have a trading history for its common stock, the expected volatility assumption is based on volatilities of a peer group of similar companies whose share prices are publicly available. The peer group was developed based on companies in the biotechnology industry. The Company will continue to apply this process until a sufficient amount of historical information regarding the volatility of its own stock price becomes available.
•Expected term: The expected term represents the period of time that options are expected to be outstanding. Because the Company does not have 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.

Prior to the Separation on November 1, 2022, valuation assumptions were determined by the Company’s former parent, Ligand, using historical and implied volatility of Ligand stock to determine the expected volatility. The expected term of an award was based on historical forfeiture experience, exercise activity, and on the terms and conditions of the stock awards. The expected dividend yield was determined to be 0% given that it had not paid any dividends on common stock in the past except for 2007, during which Ligand declared a cash dividend on its common stock of $2.50 per share, and did not expect to pay cash dividends or make any other distributions on common stock in the future. The risk-free interest rate was based upon U.S. Treasury securities with remaining terms similar to the expected term of the share-based awards.

Following the Separation on November 1, 2022, the fair value of each option issued to employees was estimated on the grant date using the Black-Scholes option pricing model with the following weighted-average assumptions:

As of March 31, 2023, unrecognized share-based compensation expense related to OmniAb options was $28.5 million, which is expected to be recognized over a remaining weighted-average period of approximately 1.57 years.

As of March 31, 2023, unrecognized share-based compensation expense related to Ligand options was $4.7 million, which is expected to be recognized over a remaining weighted-average period of approximately 0.91 years.

Restricted Stock Units

Restricted stock units (“RSUs”) are awards of nontransferable shares of common stock subject to certain vesting conditions and other restrictions. RSUs generally vest over three years. The fair value of restricted stock is determined by the closing market price on the grant date.

The following table summarizes RSU activity during the three months ended March 31, 2023 under the Company’s equity awards plans:

As of March 31, 2023, unrecognized stock-based compensation expense related to OmniAb RSUs was $7.6 million, which is expected to be recognized over a remaining weighted-average period of approximately 1.47 years. The aggregate intrinsic value of OmniAb RSUs vested during the three months ended March 31, 2023 was $1.1 million.

As of March 31, 2023, unrecognized stock-based compensation expense related to Ligand RSUs was $2.0 million, which is expected to be recognized over a remaining weighted-average period of approximately 2.13 years.

Performance Restricted Stock Units

PRSUs are share awards that, upon vesting, will deliver to the holder shares of the Company’s common stock. PRSUs vest over a continued employment period and are based on the achievement of certain corporate performance or market goals.

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.

The following table summarizes the PRSU activity during the three months ended March 31, 2023, under the Company’s equity awards plans:

As of March 31, 2023, unrecognized share-based compensation expense related to OmniAb PRSUs was $1.1 million, which is expected to be recognized over a remaining weighted-average period of approximately 1.76 years.

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 initial offering period under the 2022 ESPP is longer than 24 months, commencing November 1, 2022 and ending on November 29, 2024. 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.

The aggregate number of shares of our common stock that may be issued pursuant to rights granted under the ESPP equals 2,910,291 shares of our 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 our board of directors.

As of March 31, 2023, there was $1.2 million of unrecognized share-based compensation expense associated with the ESPP, which is expected to be recognized over a remaining weighted-average period of 1.08 years.

During the three months ended March 31, 2023, there were no shares issued pursuant to the ESPP.


12. Income Taxes

Prior to the Separation on November 1, 2022, OmniAb operated as part of Ligand and not as a stand-alone company. The Company determined the OmniAb income tax provision as if Legacy OmniAb had filed consolidated federal income tax returns and combined state income tax returns separate from Ligand since its inception on January 8, 2016 when Ligand acquired Legacy OmniAb. Since November 1, 2022 the Company reports its income tax provision, deferred tax assets and liabilities, and other income tax related items to reflect actual tax attributes received when it departed Ligand’s consolidated group and its activity as a stand-alone company.

28


The Company’s effective tax rate may vary from the U.S. federal statutory tax rate due to the 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 months ended March 31, 2023 was 14.4%. The variance from the U.S. federal statutory tax rate of 21.0% for the three months ended March 31, 2023 was primarily due to the benefit related to tax credits, the tax impact of stock award activities, and the valuation allowance established on state attributes in the current period. The effective tax rate for the three months ended March 31, 2022 was 23.6%. The variance from the U.S. federal statutory tax rate of 21.0% for the three months ended March 31, 2022 was primarily due to the benefit related to tax credits, repricing of state tax deferrals, and the tax impact of stock award activities.

The Company has 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 March 31, 2023.

13. 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 2 – Summary of Significant Accounting Policies, earnout shares issued in connection with the Business Combination, as further described in Note 4 – 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. For periods prior to the Business Combination, basic and diluted loss per share was calculated based on 82.6 million shares issued to Ligand shareholders at the Closing Date.

The following table outlines the basic and diluted net loss per share for the three months ended March 31, 2023 and 2022:

Overview

Our mission is to enable the rapid development of innovative therapeutics by pushing the frontiers of drug discovery technologies. We intend to achieve this mission by enabling the discovery of high-quality therapeutic candidates and by being the partner of choice for pharmaceutical and biotechnology companies. We believe that pairing the large and diverse antibody repertoires generated from our proprietary transgenic animals with our cutting-edge and high-throughput validated screening tools will deliver high-quality therapeutic candidates for a wide range of diseases.

Our OmniAb technology platform creates and screens diverse antibody repertoires and is designed to quickly identify optimal antibodies for our partners’ drug development efforts. We harness the power of Biological Intelligence, which we built into our proprietary transgenic animals and paired with our high-throughput screening technologies to enable the discovery of high-quality, fully-human antibody therapeutic candidates. We believe these antibodies are high quality because they are naturally optimized in our proprietary host systems for affinity, specificity, developability and functional performance. Our partners have access to these antibody candidates that are based on unmatched biological diversity and optimized through integration across a full range of technologies, including antigen design, transgenic animals, deep screening and characterization. We provide our partners both integrated end-to-end capabilities and highly customizable offerings, which address critical industry challenges and provide optimized antibody discovery solutions. As of March 31, 2023, we had 70 active partners with 301 active programs using the OmniAb technology, including 24 OmniAb-derived antibodies in clinical development by our partners, and three approved products of our partners: (i) zimberelimab, which was approved in China for the treatment of recurrent or refractory classical Hodgkin’s lymphoma, (ii) sugemalimab, which was approved in China for the first-line treatment of metastatic (stage IV) non-small cell lung cancer in combination with chemotherapy, as well as for patients
30


with unresectable stage III non-small cell lung cancer whose disease has not progressed following concurrent or sequential platinum-based chemoradiotherapy, and (iii) teclistamab, which received accelerated approval in the U.S. for adult patients with relapsed or refractory multiple myeloma who have received at least four prior lines of therapy, including a proteasome inhibitor, an immunomodulatory agent, and an anti-CD38 monoclonal antibody, and conditional marketing authorization in Europe as monotherapy for the treatment of adult patients with relapsed and refractory multiple myeloma.

We partner with numerous pharmaceutical and biotechnology companies, varying in size, clinical stage, geography and therapeutic focus. Our license agreements are negotiated separately for each discovery partner, and as a result, the financial terms and contractual provisions vary from agreement to agreement. We structure our license agreements with partners to typically include: (i) upfront or annual payments for technology access (license revenue) and payments for performance of research services (service revenue); (ii) downstream payments in the form of preclinical, intellectual property, clinical, regulatory, and commercial milestones (milestone revenue); and (iii) royalties on net sales of our partners’ products, if any. We succeed when our partners are successful and our agreements are structured to align economic and scientific interests. Our typical royalty rates for antibody discovery contracts are currently in the low- to mid-single digits, and can vary depending on the other economic terms in the agreement. Our future success and the potential to receive these payments are entirely dependent on our partners’ efforts over which we have no control. If our partners determine not to proceed with the future development of a drug candidate, we will not receive any future payments related to that program. Additionally, unless publicly disclosed by our partners, we do not have access to information related to our partners’ clinical trial results, including serious adverse events, or ongoing communications with regulatory agencies regarding our partners’ current clinical programs, which limits our visibility into how such programs may be progressing.

Historically, our revenue has been derived from payments for technology access, collaborative research services and milestones. We believe the long-term value of our business will be driven by partner royalties as such payments are based on global sales of potential future partner antibodies, 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 in the United States and Europe. However, drug discovery and development has significant uncertainty in timing and likelihood of reaching marketing authorization, 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 antibodies discovered using our platform, and as a result, we are entirely dependent on our partners’ efforts and decisions with respect to such antibodies.

Closing of the Business Combination and Separation from Ligand

On November 1, 2022 (the “Closing Date”), we, Ligand Pharmaceuticals Incorporated, a Delaware corporation (“Ligand” or the “Parent”), OmniAb Operations, Inc., a Delaware corporation and wholly-owned subsidiary of Ligand (“Legacy OmniAb”, formerly known as OmniAb, Inc. and, together with Ligand, collectively, the “Companies”), 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.

In connection with, and as contemplated by, the Merger Agreement, on November 1, 2022, in accordance with the terms of the Separation and Distribution Agreement, dated as of March 23, 2022, by and among APAC, Ligand and Legacy OmniAb (the “Separation Agreement”), Ligand transferred the Legacy OmniAb business, including certain related subsidiaries of Ligand, to Legacy OmniAb and made a contribution to the capital of Legacy OmniAb of $1.8 million, after deducting certain transaction and other expenses reimbursable by Legacy OmniAb (the “Separation”). Following the Separation, as contemplated by the Separation Agreement, Ligand distributed on a pro rata basis to its stockholders all of the shares of common stock, par value $0.001 per share, of Legacy OmniAb (“Legacy OmniAb Common Stock”) held by Ligand, such that each holder of shares of common stock, par value $0.001 per share, of Ligand (“Ligand Common Stock”) was entitled to receive one share of Legacy OmniAb Common Stock for each share of Ligand Common Stock held by such holder as of the record date for the distribution, October 26, 2022 (the “Distribution”).

Following the Separation and Distribution, on November 1, 2022, we consummated the Business Combination, by and among us (formerly known as APAC), Ligand, Legacy OmniAb and Merger Sub, pursuant to which Merger Sub merged with and into Legacy OmniAb, with Legacy OmniAb becoming a wholly owned subsidiary of OmniAb.

Prior to completion of the Separation, on November 1, 2022, Legacy OmniAb operated as part of Ligand and not as a separate, publicly-traded company. Legacy OmniAb’s combined financial statements were derived from Ligand’s historical accounting records and were presented on a carve-out basis. All revenues and expenses as well as assets and liabilities directly associated with Legacy OmniAb’s business activity were included as a component of the combined financial statements. The
31


combined financial statements also included allocations of certain general, administrative, sales and marketing expenses from Ligand’s corporate office and from other Ligand businesses to Legacy OmniAb and allocations of related assets, liabilities, and Ligand’s investment, as applicable. We believe the allocations have been determined on a reasonable basis; however, the amounts were not necessarily representative of the amounts that would have been reflected in the combined financial statements had Legacy OmniAb been an entity that operated separately from Ligand during the periods presented.

Following the Separation, we began accounting for our financial activities as an independent entity. Our financial statements as of December 31, 2022 and March 31, 2023 and for the three months ended March 31, 2023 are based on the reported results of OmniAb as a standalone company. The accompanying condensed consolidated and combined financial statements include the accounts of OmniAb and its wholly owned subsidiaries. All intercompany transactions and accounts within OmniAb have been eliminated.

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 may change or may be substituted for additional or different metrics as our business continues to grow.

Metric
March 31, 2023
December 31, 2022
% Change
Active partners70691%
Active programs 3012913%
Active clinical programs 27264%
Approved products 33—%

Active partners represents the number of partners that have an active program or have executed a license agreement in advance of initiating an active program. 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 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 represents the number of unique programs for which an Investigational New Drug Application or equivalent under other regulatory regimes has been filed based on an OmniAb-derived antibody and which are in clinical development by our partners and we continue to count programs as active as long as they are actively being developed 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 below. 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.

Results of Operations

Comparison of the Three Months Ended March 31, 2023 and 2022

Revenue
Three Months Ended March 31,
(dollars in thousands)20232022Change % Change
   License and milestone revenue$12,646 $4,101 $8,545 208 %
   Service revenue3,958 5,259 (1,301)(25)%
   Royalty revenue315 263 52 20 %
Total revenues$16,919 $9,623 $7,296 76 %

•License and milestone revenue increased primarily due to the recognition of the $10 million milestone related to the first commercial sale of teclistamab in the E.U.
•Service revenue declined as a result of less work being performed for some of our ion channel partners based on stage and status of these exclusively licensed programs.

Operating Costs and Expenses
Three Months Ended March 31,
(dollars in thousands)20232022Change% Change
   Research and development$13,759 $10,772 $2,987 28 %

   Amortization of intangibles3,369 3,405 (36)(1)%
   Other operating expense (income), net49 (443)492 (111)%
Total operating expenses$25,372 $17,846 $7,526 42 %

•Research and development expenses increased primarily due to increased personnel costs and rent expense for newly leased facilities as we invest in the growth and development of the OmniAb business.
•General and administrative expenses increased primarily due to personnel-related costs and costs associated with our obligations as a public company.
•Other operating expense, net, during the three months ended March 31, 2023 resulted from royalties owed to third parties partially offset by fair value adjustments to contingent earnout liabilities issued in connection with acquisitions. Other operating income, net, during the three months ended March 31, 2022 resulted from fair value adjustments to contingent earnout liabilities issued in connection with acquisitions.

Other income

Other income during the three months ended March 31, 2023 related to interest earned on short-term investments. There was no other income during the three months ended March 31, 2022.

Income tax benefit

Three Months Ended March 31,
(dollars in thousands)20232022Change% Change
Loss before income tax benefit$(7,129)$(8,223)$1,094 (13)%
Income tax benefit1,029 1,941 (912)(47)%
Net loss$(6,100)$(6,282)$182 (3)%
Effective Tax Rate(14.4)%(23.6)%

Our effective tax rate is affected by recurring items, such as the U.S. federal and state statutory tax rates and the relative amounts of income we earn in those jurisdictions. The tax rate is also affected by discrete items that may occur in any given year but are not consistent from year to year.

Our effective tax rate for the three months ended March 31, 2023 differed from the federal statutory tax rate of 21.0% due to share-based compensation expense that is not tax deductible and an increase to our valuation allowance recorded against deferred tax assets, partially offset by the tax benefit from research and development tax credits. Our effective tax rate for the three months ended March 31, 2022 differed from the federal statutory tax rate of 21.0% due to share-based compensation

expense that is not tax deductible, an increase to our valuation allowance recorded against deferred tax assets, and repricing of state tax deferrals, partially offset by the tax benefit of research and development tax credits.

Liquidity and Capital Resources
Prior to November 1, 2022, funding from Ligand was our primary source of liquidity. On November 1, 2022, with the closing of the Business Combination, we were capitalized with $95.8 million in net cash. As of March 31, 2023, our cash, cash equivalents and short-term investments were $113.6 million. We believe our cash, cash equivalents and short-term investments and the cash we expect to generate from operations will provide us the flexibility we need to meet operating, investing, and financing needs and support our operations through at least the next 12 months.

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;
•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 the COVID-19 pandemic or other epidemic diseases on global social, political and economic conditions;
•our efforts to enhance operational systems and hire additional personnel to satisfy our obligations as a public company;
•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.

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 the 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 Annual 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. If the market price for our common stock is less than the exercise price of the Warrants, warrant holders will be unlikely to exercise such securities. We expect to use the net proceeds from the exercise of the Warrants, if any, for general corporate and working capital purposes, although we believe we can fund our operations with cash on hand.

Critical Accounting Policies and Estimates

There have been no material changes to our critical accounting policies and estimates during the three months ended March 31, 2023, 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 2022 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 March 31, 2023, there were no material changes to our market risks from the discussion provided in Item 7A of our 2022 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 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
35


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 March 31, 2023, 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 2022 Annual Report, refer to Note 9 – Commitments and Contingencies to the condensed consolidated and combined financial statements contained in Part I, Item 1, of this report.

Item 1A. Risk Factors

We do not believe that there have been any material changes to the risk factors disclosed in Part I, Item 1A of our 2022 Annual Report. The risk factors described in our 2022 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.

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.
