These forward-looking statements are subject to a number of risks, uncertainties and assumptions, including those described in Part II, Item 1A, “Risk Factors” of this Quarterly Report. Moreover, we operate in a very competitive and rapidly changing environment, and new risks emerge from time to time. It is not possible for our management to predict all risks, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements we may make. In light of these risks, uncertainties and assumptions, the forward-looking events and circumstances discussed in this Quarterly Report may not occur and actual results could differ materially and adversely from those anticipated or implied in the forward-looking statements. In addition, statements that “we

believe” and similar statements reflect our current beliefs and opinions on the relevant subject. These statements are based upon information available to us as of the date of this Quarterly Report, and while we believe such information forms a reasonable basis for such statements, such information may be limited or incomplete, and our statements should not be read to indicate that we have conducted an exhaustive inquiry into, or review of, all potentially available relevant information. These statements are inherently uncertain and investors are cautioned not to unduly rely upon these statements.

You should not rely upon forward-looking statements as predictions of future events. Although we believe that the expectations reflected in the forward-looking statements are reasonable, we cannot guarantee that the future results, levels of activity, performance or events and circumstances reflected in the forward-looking statements will be achieved or occur. We undertake no obligation to update publicly any forward-looking statements for any reason after the date of this Quarterly Report to conform these statements to new information, actual results or to changes in our expectations, except as required by law.

You should read this Quarterly Report and the documents that we file with the SEC with the understanding that our actual future results, levels of activity, performance and events and circumstances may be materially different from what we expect. All forward-looking statements are qualified in their entirety by this cautionary statement, which is made under the safe harbor provisions of the Private Securities Litigation Reform Act of 1995.

Notes to Unaudited Condensed Consolidated Financial Statements

1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Organization

Inhibrx Biosciences, Inc., or the Company, or Inhibrx, is a clinical-stage biopharmaceutical company with a pipeline of novel biologic therapeutic candidates, developed using its proprietary modular protein engineering platforms. The Company leverages its innovative protein engineering technologies and deep understanding of target biology to create therapeutic candidates with attributes and mechanisms it believes to be superior to current approaches and applicable to a range of challenging, validated targets with high potential.

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America, or GAAP, and applicable rules and regulations of the Securities and Exchange Commission, or the SEC, related to an interim report on Form 10-Q. The unaudited condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary. All intercompany accounts and transactions have been eliminated in consolidation.

The unaudited interim condensed consolidated financial statements reflect all adjustments which, in the opinion of management, are necessary for a fair statement of the results for the periods presented. All such adjustments are of a normal and recurring nature. The operating results presented in these unaudited interim condensed consolidated financial statements are not necessarily indicative of the results that may be expected for any future periods.

Certain information and note disclosures normally included in annual financial statements prepared in accordance with GAAP have been condensed or omitted. Accordingly, the accompanying unaudited interim condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and the related notes thereto for the fiscal year ended December 31, 2024, which are included in the Company’s Annual Report on Form 10-K filed with the SEC on March 17, 2025.

Reclassification of Prior Year Presentation

Certain prior year amounts have been reclassified for consistency with the current year presentation. These reclassifications had no effect on the reported results of operations.

Separation and Distribution

In January 2024, Inhibrx, Inc., or the Former Parent, announced its intent, as approved by its board of directors, to effect the spin-off of INBRX-101, an optimized, recombinant alpha-1 antitrypsin, or AAT, augmentation therapy in a registrational trial for the treatment of patients with alpha-1 antitrypsin deficiency. The Former Parent and the Company signed an Agreement and Plan of Merger, dated as of January 22, 2024, or the Merger Agreement, with Aventis Inc., a Pennsylvania corporation, or the Acquirer, and a wholly-owned subsidiary of Sanofi S.A., or Sanofi, and Art Acquisition Sub, Inc., a Delaware corporation, or the Merger Sub, and a wholly-owned subsidiary of Acquirer, along with a Separation and Distribution Agreement, dated as of January 22, 2024, by and among the Former Parent, the Company and Acquirer. The Merger Agreement provided for the acquisition by Acquirer of the Former Parent, or the Merger, to be accomplished through the merger of Merger Sub with and into the Former Parent with the Former Parent continuing as the surviving entity.

On May 29, 2024, the Former Parent completed a distribution to holders of its shares of common stock of 92% of the issued and outstanding shares of common stock of the Company, or the Distribution. On May 30, 2024, the Former Parent completed the Merger, pursuant to which (i) all assets and liabilities primarily related to INBRX-101, or the 101 Business, were transferred to the Acquirer, a wholly-owned subsidiary of Sanofi; and (ii) by way of a series of internal restructuring transactions, or the Separation, the Company acquired the assets and liabilities and corporate infrastructure associated with its ongoing programs, INBRX-106 and ozekibart (INBRX-109), and its discovery pipeline, as well as the remaining close-out obligations related to its previously terminated program, INBRX-105. Upon the closing of the Merger, the Company became a stand-alone, publicly traded company.

In connection with the foregoing transactions, each Former Parent stockholder received: (i) $30.00 per share in cash, (ii) one contingent value right per share, representing the right to receive a contingent payment of $5.00 in cash upon the achievement of a regulatory milestone, and (iii) one SEC-registered, publicly listed, share of Inhibrx for every four shares of the Former Parent’s common stock held. The Acquirer retained an equity interest in the Company of 8% upon the Distribution.

The Acquirer paid transaction consideration of $1.9 billion, including the $30.00 per share consideration and the assumption of the Company’s third-party debt. See Note 3 for further discussion on the extinguishment of the Company’s Amended 2020 Loan Agreement with Oxford (as defined below). In addition, the Acquirer assumed all assets and liabilities under contracts primarily related to INBRX-101 upon close of the Merger. The Acquirer also reimbursed the Company or paid on behalf of the Company $68.0 million in transaction costs. The Acquirer may pay an additional $300.0 million in consideration under the contingent value rights issued upon the achievement of a regulatory milestone.

Notwithstanding the legal form of the spin-off, the Separation and Distribution is being treated as a reverse spin-off for financial accounting and reporting purposes in accordance with ASC 505-60, Spinoffs and Reverse Spinoffs because (i) a wholly-owned subsidiary of the Acquirer merged with and into the Former Parent immediately following the Distribution; (ii) no senior management of the Former Parent were retained by the Former Parent following the Distribution; and (iii) the size of the Company’s operations relative to the 101 Business. As a reverse spin-off, the Company considers Inhibrx as the accounting spinnor of the Former Parent, and the accounting successor to the Former Parent. Therefore, for periods prior to the spin-off, the Company’s financial statements are the historical financial statements of the Former Parent. For such periods, descriptions of historical business activities are presented as if the spin-off had already occurred, and the Former Parent’s activities related to such assets and liabilities had been performed by the Company. In addition, for all periods prior to the spin-off, all outstanding shares referenced in these financial statements are those shares outstanding of the Former Parent at each respective date, unless otherwise indicated as adjusted for the distribution ratio. Following the spin-off, all outstanding shares referenced are those of the Company, which, as discussed above, were issued on a four-to-one ratio of the Former Parent’s outstanding shares.

The Company evaluated the sale of the 101 Business in accordance with ASC 205-20, Discontinued Operations, and determined that the Separation does not represent a strategic shift and thus does not qualify as a discontinued operation. The Company next evaluated the sale of the 101 Business in accordance with ASC 805, Business Combinations, and determined that the 101 Business does not meet the definition of a business, given that substantially all of the fair value of the gross assets transferred is concentrated in one asset. The Company then evaluated the transaction under ASC 845, Nonmonetary Transactions, which contains guidance on the accounting for the distribution of nonmonetary assets to stockholders of an entity in a spin-off. In accordance with this guidance, the disposal of the 101 Business has been accounted for as a dividend-in-kind, with a gain recognized for the difference between the fair value and carrying value of the disposed assets.

The Company recorded a gain on the transaction of $2.0 billion during the three and six months ended June 30, 2024, which consists of the following components (in thousands):


	THREE AND SIX MONTHS ENDED JUNE 30, 2024
Merger consideration for common stock, warrants, and stock options	$	1,727,687
Book value of Amended 2020 Loan Agreement assumed by Acquirer	211,315
Book value of net assets and liabilities related to INBRX-101 assumed by Acquirer	14,496
Transaction costs paid by Acquirer	68,000
Total gain recognized	$	2,021,498

The gain related to the Merger consideration payable to shareholders of $1.7 billion was recorded, net of consideration allocated to the shares issued to Acquirer, through a reduction to retained earnings of $1.2 billion,

representing the amount of retained earnings available at the closing of the Merger, with the remaining amount of $563.8 million recorded through additional paid-in capital.

Liquidity

As of June 30, 2025, the Company had an accumulated deficit of $178.1 million and cash and cash equivalents of $186.6 million. From its inception and through June 30, 2025, the Company has devoted substantially all of its efforts to therapeutic drug discovery and development, conducting preclinical studies and clinical trials, enabling manufacturing activities in support of its therapeutic candidates, pre-commercialization activities, organizing and staffing the Company, establishing its intellectual property portfolio and raising capital to support and expand these activities.

The Company believes that its existing cash and cash equivalents will be sufficient to fund the Company’s operations for at least 12 months from the date these unaudited condensed consolidated financial statements are issued. The Company plans to finance its future cash needs through equity offerings, debt financings or other capital sources, including potential collaborations, licenses, strategic transactions and other similar arrangements.

If the Company does raise additional capital through public or private equity or convertible debt offerings, the ownership interests of its existing stockholders will be diluted, and the terms of those securities may include liquidation or other preferences that adversely affect its stockholders’ rights. If the Company raises capital through additional debt financings, it may be subject to covenants limiting or restricting its ability to take specific actions, such as incurring additional debt or making certain capital expenditures. To the extent that the Company raises additional capital through strategic licensing, collaboration or other similar agreements, it may have to relinquish valuable rights to its therapeutic candidates, future revenue streams or research programs at an earlier stage of development or on less favorable terms than it would otherwise choose, or to grant licenses on terms that may not be favorable to the Company. There can be no assurance as to the availability or terms upon which such financing and capital might be available in the future. If the Company is unable to secure adequate additional funding, it will need to reevaluate its operating plan and may be forced to make reductions in spending, extend payment terms with suppliers, liquidate assets where possible, delay, scale back or eliminate some or all of its development programs, or relinquish rights to its technology on less favorable terms than it would otherwise choose. These actions could materially impact its business, financial condition, results of operations and prospects.

The rules and regulations of the SEC or any other regulatory agencies may restrict the Company’s ability to conduct certain types of financing activities, or may affect the timing of and amounts it can raise by undertaking such activities.

Use of Estimates

The preparation of these unaudited condensed consolidated financial statements in conformity with GAAP requires the Company to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue and expense and the disclosure of contingent assets and liabilities in the Company’s financial statements and accompanying notes. The Company’s most significant estimates relate to evaluation of whether revenue recognition criteria have been met, accounting for development work and preclinical studies and clinical trials, determining the assumptions used in measuring stock-based compensation, the fair value of warrants, and the incremental borrowing rate estimated in relation to the Company’s operating lease. The Company bases its estimates on historical experience, known trends and other market-specific or other relevant factors that it believes to be reasonable under the circumstances. Estimates are periodically reviewed in light of changes in circumstances, facts and experience. Changes in estimates are recorded in the period in which they become known. The Company’s actual results may differ from these estimates under different assumptions or conditions.

Cash and Cash Equivalents

Cash and cash equivalents are comprised of cash held in financial institutions including readily available checking, overnight sweep, and money market accounts.

Concentrations of Credit Risk

Financial instruments that subject the Company to significant concentrations of credit risk consist primarily of cash and cash equivalents. The Company maintains deposits in federally insured financial institutions in excess of

federally insured limits by the Federal Deposit Insurance Corporation, or the FDIC, of up to $250,000. The Company’s cash management and investment strategy limits investment instruments to investment-grade securities with the objective to preserve capital and to maintain liquidity until the funds can be used in operations. The Company has not experienced any losses in such accounts and believes it is not exposed to significant risk on its cash balances due to the financial condition of the depository institutions in which those deposits are held.

Fair Value Measurements

The Company determines the fair value measurements of applicable assets and liabilities based on a three-tier fair value hierarchy established by accounting guidance and prioritizes the inputs used in measuring fair value. These tiers include:

•Level 1 - Quoted prices in active markets for identical assets or liabilities.

•Level 2 - Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

•Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, the level in the fair value hierarchy within which the fair value measurement in its entirety falls has been determined based on the lowest level input that is significant to the fair value measurement in its entirety. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability.

As of June 30, 2025 and December 31, 2024, the Company held $183.4 million and $149.0 million, respectively, of money market mutual funds or equivalents, which are classified as Level 1 in the fair value hierarchy. The Company’s long-term outstanding debt as of June 30, 2025, which approximates fair value, is classified as Level 2 in the fair value hierarchy.

Accrued Research and Development and Clinical Trial Costs

Research and development costs are expensed as incurred based on estimates of the period in which services and efforts are expended, and include the cost of compensation and related expenses, as well as expenses for third parties who conduct research and development on the Company’s behalf, pursuant to development and consulting agreements in place. The Company’s preclinical studies and clinical trials are performed internally, by third party contract research organizations, or CROs, and/or clinical investigators. The Company also engages with contract development and manufacturing organizations, or CDMOs, for clinical supplies and manufacturing scale-up activities related to its therapeutic candidates. Invoicing from these third parties may be monthly based upon services performed or based upon milestones achieved. The Company accrues these expenses based upon estimates determined by reviewing cost information provided by CROs and CDMOs, other third-party vendors and internal clinical personnel, and contractual arrangements with CROs and CDMOs and the scope of work to be performed. Costs incurred related to the Company’s purchases of in-process research and development for early-stage products or products that are not commercially viable and ready for use, or have no alternative future use, are charged to expense in the period incurred. Costs incurred related to the licensing of products that have not yet received marketing approval to be marketed, or that are not commercially viable and ready for use, or have no alternative future use, are charged to expense in the period incurred.

Income Taxes

Income taxes are accounted for under the asset and liability method. Deferred income taxes are recorded for temporary differences between financial statement carrying amounts and the tax basis of assets and liabilities. Deferred tax assets and liabilities reflect the tax rates expected to be in effect for the years in which the differences are expected to reverse. A valuation allowance is provided if it is more likely than not that some or all of the deferred tax assets will not be realized.

Earnings (Loss) Per Share

Basic earnings (loss) per share is computed by dividing net income (loss) by the weighted average number of common stock outstanding during the same period. Diluted earnings (loss) per share is computed by dividing net income (loss) by the weighted average number of common stock and potentially dilutive common shares outstanding during the same period. The Company excludes common stock equivalents from the calculation of diluted net earnings (loss) per share when the effect is anti-dilutive.

The weighted average number of common stock used in the basic and diluted net income (loss) per common stock calculations includes the weighted-average pre-funded warrants outstanding during the period as they are exercisable at any time for nominal cash consideration.

During the three and six months ended June 30, 2024, outstanding shares during the period consist of shares of the Former Parent. For purposes of computing net loss per share only, for all periods presented in its condensed consolidated statements of operations, the Company adjusted all outstanding shares of the Former Parent, including potentially dilutive securities, by the four-to-one distribution ratio used in the Distribution.

In periods in which the Company has a net loss, basic loss per share and diluted loss per share are identical since the effect of potentially dilutive common shares is anti-dilutive and therefore excluded. Accordingly, for the three and six months ended June 30, 2025, there is no difference in the number of shares used to calculate basic and diluted shares outstanding.

Potentially dilutive securities not included in the calculation of diluted loss per share are as follows (in thousands):


			AS OF JUNE 30,
			2025

Outstanding stock options			3,647

Warrants to purchase common stock			141
Total			3,788

In periods in which the Company has a net income, the Company applies the treasury stock method to determine the dilutive effect of potentially dilutive securities. Potentially dilutive securities included in the diluted earnings per share are as follows (in thousands):


	THREE MONTHS ENDED JUNE 30, 2024	SIX MONTHS ENDED JUNE 30, 2024
Outstanding stock options	187	365
Warrants to purchase common stock	1	1

Segment Information

Operating segments are identified as components of an enterprise about which separate discrete financial information is available for evaluation by the chief operating decision-maker, or CODM, in making decisions regarding resource allocation and assessing performance. The Company views its operations and manages its business as one operating and reportable segment as the Company has devoted substantially all of its resources to drug discovery and development activities through conducting preclinical studies and clinical trials associated with its programs, all of which aim to discover and develop biologic therapeutic candidates.

The CODM assesses performance for the biologic therapeutic segment and decides how to allocate resources based on the condensed consolidated net income (loss) as reported on its condensed consolidated income statement. The accounting policies of the reportable segment are the same as those described in the summary of significant accounting policies. The measure of segment assets is reported on the condensed consolidated balance sheet as total consolidated assets. The segment depreciation expense, gain related to transaction with Acquirer, interest expense,

interest income, and segment asset additions are consistent with consolidated amounts reported within the condensed consolidated statement of cash flows given the Company's operations are aggregated within a single reportable segment.

The Company has incurred operating losses since its inception and expects to continue to incur significant expenses and operating losses for the foreseeable future as it advances its therapeutic candidates through all stages of development and clinical trials and, ultimately, seeks regulatory approval.

The CODM uses net loss and the components of operating expense to assess the Company’s operating results and performance and make operating decisions regarding the allocation of resources to best support the long-term growth of the Company’s overall business.

The table below summarizes the significant segment expenses which are regularly reported to and reviewed by the CODM for the purposes of making decisions regarding the allocation of resources and are reconciled to condensed consolidated net income (loss) for the three and six months ended June 30, 2025 and June 30, 2024 (in thousands):

Recent Accounting Pronouncements

From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board, or FASB, or other standard setting bodies. The Company believes that the impact of the recently issued accounting pronouncements that are not yet effective will not have a material impact on its condensed consolidated financial condition or results of operations upon adoption.

Recently Issued but Not Yet Adopted Accounting Pronouncements

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvement to Income Tax Disclosures to enhance the transparency and decision usefulness of income tax disclosures. Two primary enhancements related to this ASU include disaggregating existing income tax disclosures relating to the effective tax rate reconciliation and income taxes paid. ASU 2023-09 is effective for annual periods beginning after December

15, 2024 on a prospective basis. Early adoption is permitted. The Company is currently evaluating the impact of this accounting standard update on the Company’s condensed consolidated financial statements and related disclosures.

In November 2024, the FASB issued ASU 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, which requires additional disclosure about specific expense categories in the notes to financial statements. The amendments are effective for fiscal years beginning after December 15, 2026, and for interim periods within fiscal years beginning after December 15, 2027. Early adoption is permitted. The amendments should be applied either prospectively to financial statements issued for reporting periods after the effective date of this ASU or retrospectively to any or all prior periods presented in the financial statements. The Company is currently evaluating the impact of this accounting standard update on the Company’s condensed consolidated financial statements and related disclosures.
