LIMINATUS PHARMA, INC.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

Note 1. Description of Organization and Business Operations

Liminatus Pharma, Inc. (the “Company”), a Delaware corporation, is a pre-clinical stage biopharmaceutical company developing novel, immune-modulating cancer therapies. The Company’s candidate, IBA101, is a humanized anti CD47 monoclonal antibody. The next generation CD47 checkpoint inhibitor’s initial indication is expected to be patients with advanced solid cancers including non-small cell lung cancer.

The Company is subject to the uncertainty of whether the Company’s intellectual property will develop into successful commercial products.

Business Combination

On November 30, 2022, Iris Acquisition Corp, a Delaware corporation (“Iris”), the Company, Liminatus Pharma, LLC, a Delaware limited liability company (“Liminatus”), Liminatus Pharma Merger Sub, Inc., a Delaware corporation and wholly-owned subsidiary of the Company (“Liminatus Merger Sub”), and SPAC Merger Sub, Inc., a Delaware corporation and wholly-owned subsidiary of the Company (“SPAC Merger Sub”), entered into a business combination agreement (as amended, the “Business Combination Agreement”).

On March 4, 2025, Iris held a special meeting of stockholders. At the special meeting, Iris’s stockholders voted to approve the Business Combination and adopt the Business Combination Agreement, among other items. In connection with the special meeting, stockholders holding 59,844 Iris Class A Shares properly exercised their right to redeem their shares for cash at a redemption price of approximately $11.74 per share, subject to adjustment for taxes payable from the trust account, for an aggregate redemption amount of $702,359. The redemptions were settled on April 30, 2025 upon the consummation of the Business Combination.

On April 30, 2025 (the “Closing Date”), the Company consummated the business combination contemplated by the Business Combination Agreement, pursuant to which (a) Liminatus Merger Sub merged with and into Liminatus (the “Liminatus Merger”), with Liminatus surviving the Liminatus Merger as a direct wholly-owned subsidiary of the Company, and (b) simultaneously with the Liminatus Merger, SPAC Merger Sub merged with and into Iris (the “SPAC Merger” and, together with the Liminatus Merger, the “Mergers”), with Iris surviving the SPAC Merger as a direct wholly-owned subsidiary of the Company (the transactions contemplated by the foregoing clauses (a) and (b) the “Business Combination”), and in connection therewith the Company changed its name from “Iris Parent Holding Corp.” to “Liminatus Pharma, Inc.”

Pursuant to the Business Combination Agreement, among other matters, at the effective time of the Business Combination (the “Effective Time”), (i) every issued and outstanding security issued by Iris during its initial public offering (each, an “Iris Unit”) was automatically separated and broken out into its constituent parts and the holder thereof was deemed to hold one share of Iris Class A common stock, par value $0.0001 per share (the “Iris Class A Shares”) and one-fourth of one redeemable warrant that was included as part of each Iris Unit (the “Public Warrants”), and such underlying constituent securities of Iris were converted in accordance with the applicable terms of the Business Combination Agreement, (ii) at the Effective Time, each issued and outstanding Iris Class A Share was converted automatically into and thereafter represent the right to receive one share of common stock, par value $0.0001 per share (“Common Stock”), of the Company, following which all Iris Class A Shares ceased to be outstanding and were automatically canceled and ceased to exist, (iii) at the Effective Time, each issued and outstanding Public Warrant immediately and automatically represented the right to purchase shares of Common Stock on the same terms and conditions as are set forth in the applicable warrant agreement, (iv) at the Effective Time, each issued and outstanding non-redeemable warrant of Iris that was issued by Iris in a private placement at the time of the consummation of its initial public offering, entitling the holder thereof to purchase one Iris Class A Share at $11.50 per share, except those issued to Cantor Fitzgerald & Co. (“Cantor”), were forfeited, and (v) the private placement warrants issued to Cantor immediately and automatically represented the right to purchase shares of Common Stock.

Upon the consummation of the Business Combination, the Company’s certificate of incorporation was amended and restated to, among other things, set the total number of authorized shares of capital to 501,000,000 shares, of which 500,000,000 were designated as common stock, $0.0001 par value per share, and 1,000,000 shares were designated as preferred stock, $0.0001 par value per share.

At the Closing Date, 7,014,633 shares of Iris Class A Shares automatically converted into shares of the Company’s common stock, on a one-for-one basis. Of the total 7,014,633 newly converted shares, 6,900,000 were issued to Iris Acquisition Holdings, LLC, the sponsor of Iris, and 114,633 were issued to Iris’ public stockholders in a noncash transaction.

Table of Contents

At the Closing Date, the Company issued an aggregate of 1,500,000 shares of the Company’s common stock in a private placement (the “PIPE Shares”) for the total consideration of $15,000,000 (the “PIPE Financing”). The PIPE Financing consisted of a cash and non-cash component. Under the cash component, the Company received gross proceeds of $10,556,500, of which $7,129,500 came directly from the PIPE investor and $3,427,000 were funded indirectly by the PIPE investor, through promissory notes between Prophase Sciences, LLC, a related party of the Company, and Liminatus. At the Closing Date, the $3,427,000 in related party debts between Prophase Sciences, LLC and Liminatus was ultimately converted into shares as part of the PIPE Financing. As part of the PIPE Financing, the gross proceeds satisfied principal and accrued interest totaling $3,316,756, which was ultimately converted into shares as part of the PIPE Financing. The non-cash component of the PIPE Financing included the conversion of $4,443,500 in amounts borrowed from a consortium of related parties. The $4,443,500 borrowed from the related parties was used to fund an unsecured promissory note between Liminatus and Iris. At the Closing Date, the unsecured promissory note was settled and the $4,443,500 in related party debts were ultimately converted into shares of the Company in a noncash transaction.

At the Closing Date, 112,222,220 of Liminatus’ member units converted into 17,500,000 shares of the Company’s common stock. Of the 17,500,000 shares of common stock, 4,000,000 were issued to Feelux Co, Ltd. as part of an agreement between the Company, Feelux Co, Ltd. and Car-Tcellkor, Inc. As part of the agreement, the outstanding principal and accrued interest on the Feelux and Car-Tcellkor bonds, totaling $11,481,146, and 9,999,999 member units of Liminatus were converted into 4,000,000 shares of the Company’s common stock. The remaining Liminatus member units were converted based on a conversion ratio of 0.1559 shares per member unit.

Upon consummation of the Business Combination, the Company assumed a total of $10,694,604 in liabilities from Iris. The Company incurred $1,518,381 in transaction costs associated with the closing of the Business Combination. The Company converted a total of $14,797,901 of related party debt and accrued interest, $3,316,756 from the PIPE investor and $11,481,146 from Feelux and Car-Tcellkor (as described above) into common stock. Additionally, a total of $169,201 in accrued interest on related party debts that were converted, as discussed above, was eliminated upon consummation of the Business Combination.

In addition, at the Closing Date, the Company settled Iris’ liabilities for $7,000,000 of the deferred underwriting fees incurred prior to the Closing Date for 700,000 shares of common stock to the underwriters in Iris’s initial public offering. At the Closing Date, the shares were not issued to the underwriter and the Company recorded as a liability with a fair value of $7,049,000. On July 1, 2025, the Company issued the shares to the underwriters, which on July 1, 2025 had a fair value of $7,245,000.

Liminatus was deemed the accounting acquirer in the Business Combination based on an analysis of the criteria outlined in Accounting Standards Codification (“ASC”) 805, Business Combinations (“ASC 805”). The determination was primarily based on Liminatus’ members prior to the Business Combination having a majority of the voting interests in the combined company, Liminatus’ ability to exert control over the majority of the board of directors of the combined company, Liminatus’ ability to maintain control of the board of directors on a go-forward basis, Liminatus’ senior management comprising the senior management of the combined company, and Liminatus’ operations prior to the Business Combination comprise the ongoing operations of the combined company. Accordingly, for accounting purposes, the Business Combination was treated as the equivalent of Liminatus’ issuing stock for the net assets of Iris, accompanied by a recapitalization. The net assets of Iris were stated at fair value, with no goodwill or other intangible assets recorded.

Upon the consummation of the Business Combination, the Iris Class A Shares, Iris Units and Public Warrants ceased trading on the OTC Pink Marketplace, and the Common Stock and Public Warrants began trading on The Nasdaq Stock Market (“Nasdaq”) under the trading symbols “LIMN” and “LIMNW,” respectively.

Notices from Nasdaq

On August 22, 2025, the Company received a notice from the Nasdaq Listing Qualifications Department indicating that the Company was no longer in compliance with Nasdaq Listing Rule 5250(c)(1) due to the delay in filing its Quarterly Report on Form 10-Q for the period ended June 30, 2025. The deficiency letter had no immediate effect on the listing of the Company’s common stock, and its common stock continued to trade on Nasdaq under the symbol “LIMN”. Under the Nasdaq rules, the Company had 60 calendar days, or until October 21, 2025, to submit a plan to regain compliance and if the plan was accepted, Nasdaq can grant an exception of up to 180 calendar days from the filing’s due date, or until February 16, 2026, to regain compliance. If the compliance plan was not accepted, the Company had the opportunity to appeal that decision to a Nasdaq Hearings Panel. On October 6, 2025, the Company filed its Form 10-Q for the period ended June 30, 2025 and the matter was closed.

On November 19, 2025, the Company received notices from the Nasdaq indicating that the Company was no longer in compliance with (i) Nasdaq Listing Rule 5450(b)(2)(A) due to its failure to maintain a minimum Market Value of Listed Securities (“MVLS”) of

Table of Contents

$50,000,000 (the “MVLS Rule”), based upon a review of the Company’s MVLS for the last 30 consecutive business days and (ii) Nasdaq Listing Rule 5450(b)(2)(C) due to its failure to maintain a minimum Market Value of Publicly Held Shares (“MVPHS”) of $15,000,000 (the “MVPHS Rule”), based upon a review of the Company’s MVPHS for the last 30 consecutive business days. The Nasdaq staff noted that the Company also does not meet the requirements under Listing Rule 5450(b)(3)(A), which requires the Company to have total assets and total revenue of at least $50 million each for the most recently completed fiscal year or two of the three most recently completed fiscal years. Under the Nasdaq rules, the Company has 180 calendar days, or until May 18, 2026, to regain compliance with the MVLS Rule and MVPHS Rule. In the event the Company does not regain compliance with the MVLS Rule and MVPHS Rule prior to the expiration of the compliance period, it will receive written notification that its securities are subject to delisting. At that time, the Company may appeal the delisting determination to a Nasdaq Hearings Panel. Alternatively, the Company may consider applying to transfer the Company’s securities to the Capital Market, provided it meets the Capital Market’s continued listing requirements. The Company is working diligently to regain compliance with Nasdaq’s listing rules. However, there can be no assurance that the Company will be able to regain compliance within the prescribed time period.

On January 15, 2026, the Company received a notice from Nasdaq indicating that, based upon the closing bid price for the last 30 consecutive business days, the Company was no longer in compliance with Nasdaq Listing Rule 5450(a)(1) (the “Bid Price Rule”) which requires listed securities to maintain a minimum bid price of $1 per share. Under the Nasdaq rules, the Company has 180 calendar days, or until July 14, 2026, to regain compliance with the Bid Price Rule. In the event the Company does not regain compliance during the initial compliance period, the Company may be eligible for additional time to regain compliance with the Bid Price Rule. The Company is working diligently to regain compliance with Nasdaq’s listing rules. However, there can be no assurance that the Company will be able to regain compliance within the prescribed time period.

February 2026 Public Offering

On February 18, 2026, the Company closed a best efforts public offering for the sale of (i) 8,270,000 shares of common stock, (ii) 5,543,000 pre-funded warrants to purchase up to 5,543,000 shares of common stock and (iii) 13,813,000 common stock purchase warrants to purchase up to 20,719,500 shares of common stock, at a combined public offering price of $0.29 per share (or $0.2899 per pre-funded warrant) and accompanying warrant (the “Offering”), for aggregate net proceeds of approximately $3.44 million after deducting the estimated offering expenses, including the placement agent fees. Each pre-funded warrant has an exercise price of $0.0001 per share upon issuance for one share of common stock and will not expire prior to exercise. Each warrant has an exercise price of $0.29 per share, is exercisable upon issuance for one and a half shares of common stock, and will expire five years following the date of issuance. The exercise price and number of shares of common stock issuable upon exercise is subject to appropriate adjustment in the event of stock dividends, stock splits, reorganizations or similar events affecting the common stock and the exercise price. Maxim Group LLC acted as the placement agent in connection with the Offering.

In connection with the Offering, on February 17, 2026, the Company entered into a securities purchase agreement (the “Purchase Agreement”) with certain purchasers party thereto. Pursuant to the Purchase Agreement, the Company agreed not to issue, enter into any agreement to issue or announce the issuance or proposed issuance of any shares of common stock or any securities convertible into or exercisable or exchangeable for shares of common stock or file any registration statement or prospectus, or any amendment or supplement thereto for 180 days after the closing date of the Offering, subject to certain exceptions. The Company also agreed not to effect or enter into an agreement to effect any issuance of common stock or any securities convertible into or exercisable or exchangeable for shares of common stock involving a Variable Rate Transaction (as defined in the Purchase Agreement) until 180 days after the closing date of the Offering, subject to certain exceptions.

In connection with the Offering, on February 17, 2026, the Company entered into a placement agency agreement with Maxim Group LLC, as placement agent in connection with the Offering (the “Placement Agent”). The Company paid the Placement Agent a cash fee of 8.0% of the aggregate gross proceeds raised in the Offering. The Company also agreed to reimburse the Placement Agent for all reasonable out-of-pocket costs and expenses incurred in connection with the Offering in an aggregate amount up to $100,000. In addition, the Company issued to the Placement Agent warrants (the “Placement Agent Warrants”) to purchase 690,650 shares of common stock (representing 5.0% of the number of shares of common stock sold in the Offering). The Placement Agent Warrants are immediately exercisable at an exercise price of $0.319 (or 110% of the public offering price for the shares of common stock and common warrants offered in the Offering) and will expire on the fifth anniversary of the commencement of sales of the Offering.

Liquidity and Capital Resources

Table of Contents

Through March 31, 2026, the Company has funded its operations mainly through equity and debt financings, including the proceeds from the Mergers and the PIPE Financing and the Offering (as described below).

As of March 31, 2026, the Company had $1,907,674 of cash in its bank accounts. As of March 31, 2026 and December 31, 2025, there was $1,442,500 of related party debts, which are included in short-term debt, related parties in the accompanying unaudited condensed consolidated balance sheets (see Note 4).

The Company has an accumulated deficit of $39,995,447 as of March 31, 2026. The Company had a loss from operations and net loss of $1,100,898 and $1,123,714, respectively, for the three months ended March 31, 2026. The Company had a loss from operations and net loss of $264,220 and $327,526, respectively, for the three months ended March 31, 2025.

On February 18, 2026, the Company completed a “best efforts” public offering of (i) 8,270,000 shares of its common stock, (ii) 5,543,000 Pre-Funded Warrants to purchase up to 5,543,000 shares of common stock and (ii) 13,813,000 Common Stock Warrants to purchase up to 20,719,500 shares of common stock, at a combined public offering price of $0.29 per share (or $0.2899 per Pre-Funded Warrant) and accompanying warrant. In connection with the Offering, the Company received net proceeds of approximately $3.44 million, after deducting the estimated offering expenses payable by the Company, including the placement agent fees.

In connection with the Company’s assessment of going concern considerations in accordance with Financial Accounting Standards Board (“FASB”) ASC 205-40, Presentation of Financial Statements—Going Concern, management has concluded that there is substantial doubt about its ability to continue as a going concern for one year after the date that the accompanying unaudited condensed consolidated financial statements are issued. The Company’s unaudited condensed consolidated financial statements do not include any adjustments relating to the recovery of the recorded assets or the classification of the liabilities that might be necessary should the Company be unable to continue as a going concern.

Management’s plans relating to the above include raising additional cash through further equity and debt financings or other arrangements to fund operations. There can be no assurance that the Company will be able to raise adequate capital under acceptable terms, if at all. The sale of additional equity may dilute existing members and newly issued equity securities may contain senior rights and preferences compared to currently outstanding common stock. Issued debt securities may contain covenants and limit the Company’s ability to pay dividends or make other distributions to stockholders. If the Company is unable to obtain such additional financing, future operations would need to be reevaluated.

Note 2. Significant Accounting Policies

Basis of Presentation

The Company’s unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) as determined by the FASB ASC and pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). The unaudited condensed consolidated financial statements include the accounts of the Company and its consolidated subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. The unaudited condensed consolidated financial statements do not include all of the disclosures required by U.S. GAAP for annual consolidated financial statements and should be read in conjunction with the audited consolidated financial statements of the Company as of and for the year ended December 31, 2025 (the “Annual Financial Statements”). In the opinion of the Company, the accompanying unaudited condensed consolidated financial statements contain all adjustments, consisting of only normal recurring adjustments, necessary to fairly present its financial position as of March 31, 2026, its results of operations for the three months ended March 31, 2026 and 2025, its cash flows for the three months ended March 31, 2026 and 2025, and its changes in stockholders’ deficit for the three months ended March 31, 2026 and 2025. Results of operations for the interim periods are not necessarily indicative of the results to be expected for the full year ending December 31, 2026 or any future period. The condensed consolidated balance sheet as of December 31, 2025 was derived from the Annual Financial Statements but does not contain all of the footnote disclosures from the Annual Financial Statements.

Emerging Growth Company Status

After the closing of the Business Combination, the Company has elected to be an “emerging growth company,” as defined in Section 2(a) of the Securities Act of 1933, as amended (the “Securities Act”), as modified by the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”), and it may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the auditor

Table of Contents

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

Further, Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under Securities Exchange Act of 1934, as amended (the “Exchange Act”) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. The Company has elected not to opt out of such extended transition period which means that when a standard is issued or revised and it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of the Company’s unaudited condensed consolidated financial statements with another public company which is neither an emerging growth company nor an emerging growth company which has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used.

Use of Estimates

The preparation of the unaudited condensed consolidated financial statements in conformity with U.S. GAAP requires the Company’s management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the unaudited condensed consolidated financial statements and the reported amounts of expenses during the reporting periods. Actual results may differ materially and adversely from these estimates. The Company is not aware of any significant estimates that required management to exercise significant judgment with the exception of the Company’s warrant liability and research and development costs. If the underlying estimates and assumptions upon which the estimates are based change in the future, actual amounts may differ from those included in the Company’s unaudited condensed consolidated financial statements.

Segments

The Company’s chief operating decision maker (“CODM”), the Chief Executive Officer, manages the Company’s business activities as a single operating and reportable segment. Accordingly, the Company’s CODM uses net income/loss to measure the Company’s single segment’s performance and allocate resources. Further, the CODM reviews and utilizes functional expenses (general and administrative and research and development) to manage the Company’s operations. The Company’s general and administrative expenses for the three months ended March 31, 2026 and 2025 included $60,500 and $37,500, respectively, of compensation expenses related to the compensation agreement the Company has executed with its Chief Executive Officer. The remaining general and administrative expenses are related to legal and accounting-related expenses for contractors. The Company’s research and development expenses did not include any compensation-related expenses. Other segment items included in net loss are interest expense, related parties and interest income which are reflected in the Company’s unaudited condensed consolidated statements of operations.

Cash

Financial instruments that potentially subject the Company to concentration of credit risk consist of cash accounts in a financial institution which can exceed government insured limits.

The Company considers all highly liquid investments with an original maturity of three months or less at the date of purchase to be cash equivalents. The Company did not have any cash equivalents as of March 31, 2026 and December 31, 2025.

Fair Value of Financial Instruments

The Company’s financial assets and liabilities are accounted for in accordance with FASB ASC 820, Fair Value Measurements and Disclosures, which defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date.

Table of Contents

The fair value hierarchy requires an entity to maximize the use of observable inputs when measuring fair value and classifies those inputs into three levels:

Level 1 — Observable inputs, such as quoted prices in active markets for identical assets or liabilities.

Level 2 — Inputs other than Level 1 inputs that are either directly or indirectly observable, 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 instrument’s anticipated life.

Level 3 — Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions.

To the extent the valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgement. Accordingly, the degree of judgement exercised by management in determining fair value is greatest for instruments categorized as Level 3. A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. The fair value of the warrant liability reported in the Company’s unaudited condensed consolidated balance sheets represent a Level 3 instrument (see Note 8).

The carrying values reported in the Company’s unaudited condensed consolidated balance sheets for prepaid expenses and other current assets, due from related party, accounts payable and accrued expenses, accrued interest, short-term debt with related parties, due to related parties and its deferred underwriting fee payable are reasonable estimates of their fair values due to the short-term nature of these items.

Warrants

The Company accounts for warrants as either equity-classified or liability-classified instruments based on an assessment of the warrant’s specific terms and applicable authoritative guidance in ASC 480, Distinguishing liabilities from equity (“ASC 480”), and ASC 815, Derivatives and Hedging (“ASC 815”). The assessment considers whether the warrants are freestanding financial instruments pursuant to ASC 480, meet the definition of a liability pursuant to ASC 480, and whether the warrants meet all of the requirements for equity classification under ASC 815, including whether the warrants are indexed to the Company’s own common shares and whether the warrant holders could potentially require “net cash settlement” in a circumstance outside of the Company’s control, among other conditions for equity classification. This assessment, which requires the use of professional judgment, is conducted at the time of warrant issuance, modification, and as of each subsequent quarterly period end date while the warrants are outstanding. As of March 31, 2026, 13,813,000 of the Company’s Common Stock Warrants, 690,650 Placement Agent Warrants and 5,094,623 Public Warrants were accounted for as equity-classified instruments and 835,555 private placement warrants were accounted for as liability-classified instruments.

For issued or modified warrants that meet all of the criteria for equity classification, the warrants are required to be recorded as a component of additional paid-in capital at the time of issuance. For issued or modified warrants that do not meet all the criteria for equity classification, the warrants are required to be recorded at their initial fair value on the date of issuance, and each balance sheet date thereafter. Changes in the estimated fair value of the liability-classified warrants are recognized as a non-cash gain or loss on the accompanying condensed consolidated statements of operations. The Company assesses the classification of its warrants at each reporting date to determine whether a change in classification between equity and liability is required. During the three months ended March 31, 2026, the Company had an unrealized gain on the change in fair value of the warrant liabilities of $4,178. During the three months ended March 31, 2025, the Company had no unrealized gain or loss on the change in fair value of the warrant liabilities.

Net Loss per Share of Common Stock

The Company complies with accounting and disclosure requirements of ASC Topic 260, Earnings Per Share. The Company has one class of common stock.

Basic net loss per share is computed by dividing the net loss by the weighted-average number of shares of common stock outstanding for the period, without consideration for potentially dilutive securities if their effect is antidilutive. Diluted net loss per share is computed by dividing the net loss by the weighted average number of shares of common stock and dilutive common stock equivalents outstanding for the period determined by using the treasury stock method. Dilutive common stock equivalents are comprised of 19,598,273 warrants, comprised of 13,813,000 Common Stock Warrants, 690,650 Placement Agent Warrants and 5,094,623 Public Warrants. For all periods

Table of Contents

presented, there is no difference in the number of shares used to calculated basic and diluted shares outstanding as inclusion of the potentially dilutive securities would be antidilutive given that their inclusion would reduce the net loss per share during the three months ended March 31, 2026 and 2025.

Research and Development Expenses

Research and development expenses consist of costs incurred by InnoBation Bio Co, Ltd. (“Innobation”) in accordance with the license agreement with Innobation and are recorded as research and development expenses as incurred (see Note 3).

Leases

The Company recognizes its leases in accordance with ASC Topic 842, Leases (“ASC 842”). Under ASC 842, lessees are required to recognize all qualified operating leases at the commencement date including a lease liability, which is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis; and a right-of-use (“ROU”) asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. The initial lease liability is equal to the future fixed minimum lease payments discounted using the Company’s incremental borrowing rate, on a secured basis. The lease term includes option renewal periods and early termination payments when it is reasonably certain that the Company will exercise those rights. The initial measurement of the ROU asset is equal to the initial lease liability plus any initial direct costs and prepayments, less any lease incentives.

The Company has leased office space for a fixed period of 10 months. In accordance with ASC 842, a short-term lease is defined as a lease that, at the commencement date, has a lease term of 12 months or less and does not include an option to purchase the underlying asset that the lessee is reasonably certain to exercise. The short-term lease election can only be made at the commencement date.

A lessee that makes this accounting policy election does not recognize a lease liability or right-of-use asset on its balance sheets. Instead, the lessee recognizes lease payments on a straight-line basis over the lease term.

Income Taxes

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

ASC 740 also clarifies the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements and prescribes a recognition threshold and measurement process for financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more-likely-than-not to be sustained upon examination by taxing authorities. There were no tax accruals relating to uncertain tax positions.

The Company recognizes accrued interest and penalties related to unrecognized tax positions as income tax expense. There were no unrecognized tax positions, and no amounts accrued for interest and penalties as of March 31, 2026 and December 31, 2025. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position. The Company has identified the United States as its only “major” tax jurisdiction. The Company is subject to income tax examinations by major taxing authorities since inception. These examinations may include questioning the timing and amount of deductions, the nexus of income among various tax jurisdictions and compliance with federal and state tax laws. No unrecognized tax benefits were identified as of March 31, 2026 or December 31, 2025.

Recently Issued Accounting Pronouncements – Not Yet Adopted

On November 4, 2024, the FASB issued Accounting Standards Update (“ASU”) 2024-03, Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses (“ASU 2024-03”), to improve financial reporting by requiring that public business entities disclose additional information about specific expense categories in the notes to financial statements at interim and annual reporting periods. The amendments in this ASU do not change or remove current expense disclosure requirements; however, the amendments affect where such information appears in the notes to financial statements because entities are required to include certain current disclosures in the same tabular format disclosure as

Table of Contents

the other disaggregation requirements in the amendments. This ASU is effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. Early adoption is permitted. The Company is currently evaluating the potential impact that the adoption of this standard will have on its unaudited condensed consolidated financial statements.

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

Note 3. License Agreements

CD47 License

In October 2022, the Company was assigned a license and development agreement, as amended, with InnoBation Bio Co., Ltd. (the “CD47 License”), whereby, effective March 31, 2023, the Company received an exclusive license to develop and commercialize products for the CD47 immune checkpoint inhibitor to treat solid cancers, and companion diagnostics used to monitor treatment with CD47 products (collectively, “CD47 Products”), from Curis Biotech Holdings LLC, the parent company of Valetudo, a related party of the Company, in exchange for 78,555,554 of Liminatus’ Class A member units. The license was recorded at Valetudo’s cost basis of zero, and the Company recorded an approximately $800,000 Class A membership interest with an offset to additional paid-in capital on the balance sheets. The Company is obligated to pay all development costs for CD47 Products.

On February 20, 2026, the Company issued a payment of $1,000,000 to Innobation for the total estimated costs associated with the preparation activities for Phase 1 clinical trials of IBA101, the Company’s product candidate. As of March 31, 2026, the Company estimated approximately 40% of the activities were completed.

As of March 31, 2026 and December 31, 2025, prepaid research and development costs of $600,000 and $0, respectively, are recorded in prepaid and other current assets in the unaudited condensed consolidated balance sheets.

On September 15, 2018, the Company issued $10,000,000 of bonds to Feelux Co., Ltd., the parent company of Car-Tcellkor, Inc. (“Car-Tcellkor”) (see below), the only holder of Liminatus’ Class A member units (the “Feelux Bonds”). The bonds bear interest at 1% per annum, compounded annually, and were due on October 30, 2021.

In connection with the issuance of the Feelux Bonds, Liminatus issued 6,666,666 equity-classified warrants to purchase member units at a price of $1.50 per unit, which expired on June 30, 2023. The fair value of the warrants to purchase member units of approximately $6,400,000 was estimated using the option pricing framework on the issuance date. The Company’s assumptions included (a) its expected stock volatility of 82.0% based on the historical volatility of a publicly traded set of peer companies, (b) the contractual term of five years, (c) the risk-free interest rate of 2.9% based on the U.S. Treasury yield curve in effect at the time of grant of the award for a five-year contractual term and (d) no expected dividends.

The $10,000,000 of proceeds from the Feelux Bonds were allocated to the bonds and warrants using the relative fair value method resulting in a debt discount for the relative fair value of the warrants of $4,499,142 that was amortized to interest expense over the term of the Feelux Bonds using the effective interest method using an effective interest rate of 21.0%.

On April 30, 2025, upon consummation of the Business Combination, the outstanding principal and accrued interest on the Feelux Bonds, totaling $10,681,146, and 9,999,999 member units of Liminatus were converted into 4,000,000 shares of the Company’s common stock.

General and administrative expenses increased by $436,678 during the three months ended March 31, 2026 as compared to the three months ended March 31, 2025 primarily due to increases in accounting and legal expenses incurred in connection with the Company now operating as publicly traded company.

In connection with the closing of the Business Combination on April 30, 2025, the loans receivable with Iris were terminated, thus no interest income is expected in future periods.

Liquidity and Capital Resources

The Company is required to evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about its ability to continue as a going concern for one year after the date that the condensed consolidated financial statements are issued. Through March 31, 2026, the Company has funded its operations mainly through equity and debt financings, including the proceeds from the Mergers and the PIPE Financing, and the Offering (as described below).

As of March 31, 2026, the Company had $1,907,674 of cash in its bank accounts. As of March 31, 2026 and December 31, 2025, there was $1,442,500 of related party debts, which are included in Short-term debt, related parties in the accompanying unaudited condensed consolidated balance sheets.

Table of Contents

On February 18, 2026, the Company completed a “best efforts” public offering of (i) 8,270,000 shares of its common stock, (ii) 5,543,000 pre-funded warrants to purchase up to 5,543,000 shares of common stock (the “Pre-Funded Warrants”) and (ii) 13,813,000 common stock purchase warrants to purchase up to 20,719,500 shares of common stock, at a combined public offering price of $0.29 per share (or $0.2899 per Pre-Funded Warrant) and accompanying warrant (the “Offering”). In connection with the Offering, the Company received net proceeds of approximately $3.44 million, after deducting the estimated offering expenses payable by the Company, including the placement agent fees.

Management’s plans relating to the above include raising additional cash through equity and debt financings or other arrangements to fund operations. There can be no assurance that the Company will be able to raise adequate capital under acceptable terms, if at all. The sale of additional equity may dilute existing members and newly issued equity securities may contain senior rights and preferences compared to currently outstanding common stock. Issued debt securities may contain covenants and limit the Company’s ability to pay dividends or make other distributions to stockholders. If the Company is unable to obtain such additional financing, future operations would need to be reevaluated.

Cash Flows

The following table summarizes our cash flows for the three months ended March 31, 2026 and 2025:


		March 31,
		2026			2025			Change			%
Net cash used in operating activities		$	(2,015,289)		$	(159,393)		$	(1,855,896)		1,164	%
Net cash used in investing activities			—			(575,000)			575,000		(100)	%
Net cash provided by financing activities			3,585,308			713,000			2,872,308		403	%
Net change in cash		$	1,570,019		$	(21,393)		$	1,591,412		(7,439)	%

Net cash used in operating activities for the three months ended March 31, 2026 increased by $1,855,896 as compared to the three months ended March 31, 2025. The increase in cash used in operating activities is primarily due to an increase in net loss during the three months ended March 31, 2026 of $935,688, when compared to the net loss for the three months ended March 31, 2025, an increase in prepaid expenses of $657,107 and an increase in payment of accounts payable and accrued expenses of $173,923 for the three months ended March 31, 2026 as compared to the same period in the prior year. The increase is further a result of operating activities, adjusted for non-cash transactions including deprecation expense of $518 and a change in fair value of warrant liabilities of $4,178 for the three months ended March 31, 2026 as compared to no such activity during the three months ended March 31, 2025

Net cash used in investing activities for the three months ended March 31, 2026 decreased by $575,000 as compared to the three months ended March 31, 2025. The decrease in cash used in investing activities is primarily to less issuances of loans to Iris prior to the Business Combination.

Net cash provided by financing activities for the three months ended March 31, 2026 increased by $2,872,308 as compared to the three months ended March 31, 2025.

Further, the Company received no proceeds from related party debt during the three months ended March 31, 2026 as compared to proceeds of $713,000 during the three months ended March 31, 2025.

Critical Accounting Policies and Estimates

The preparation of unaudited condensed consolidated financial statements and related disclosures in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and income and expenses during the periods reported. Making estimates requires management to exercise significant judgement. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the unaudited condensed consolidated financial statements, which management considered in formulating its estimate, could change in the near term due to one or more future confirming events. The actual results could materially differ from those estimates.

Warrants

The Company accounts for warrants as either equity-classified or liability-classified instruments based on an assessment of the warrant’s specific terms and applicable authoritative guidance in ASC 480, Distinguishing liabilities from equity (“ASC 480”), and ASC 815, Derivatives and Hedging (“ASC 815”). The assessment considers whether the warrants are freestanding financial instruments pursuant to ASC 480, meet the definition of a liability pursuant to ASC 480, and whether the warrants meet all of the requirements for equity classification under ASC 815, including whether the warrants are indexed to the Company’s own common shares and whether the warrant holders could potentially require “net cash settlement” in a circumstance outside of the Company’s control, among other conditions for equity classification. This assessment, which requires the use of professional judgment, is conducted at the time of warrant issuance, modification, and as of each subsequent quarterly period end date while the warrants are outstanding. As of March 31, 2026, 13,813,000 of the Company’s Common Stock Warrants, 690,650 Placement Agent Warrants and 5,094,623 of the Company’s Public Warrants were accounted for as equity-classified instruments and 835,555 private placement warrants were accounted for as liability-classified instruments.

For issued or modified warrants that meet all of the criteria for equity classification, the warrants are required to be recorded as a component of additional paid-in capital at the time of issuance. For issued or modified warrants that do not meet all the criteria for equity classification, the warrants are required to be recorded at their initial fair value on the date of issuance, and each balance sheet date thereafter. Changes in the estimated fair value of the liability-classified warrants are recognized as a non-cash gain or loss on the accompanying consolidated statements of operations and comprehensive loss. The Company assesses the classification of its warrants at each reporting date to determine whether a change in classification between equity and liability is required. During the three months ended March 31, 2026, the Company had an unrealized gain on the change in fair value of the warrant liabilities of $4,178. During the three months ended March 31, 2025, the Company had no unrealized gain or loss on the change in fair value of the warrant liabilities.

Recently Issued Accounting Pronouncements – Not Yet Adopted

On November 4, 2024, the FASB issued ASU 2024-03, Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, to improve financial reporting by requiring that public business entities disclose additional information about specific expense categories in the notes to financial statements at interim and annual reporting periods. The amendments in this ASU do not change or remove current expense disclosure requirements; however, the amendments affect where such information appears in the notes to financial statements because entities are required to include certain current disclosures in the same tabular format disclosure as the other disaggregation requirements in the amendments. This ASU is effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. Early adoption is permitted. The Company is currently evaluating the potential impact that the adoption of this standard will have on its unaudited condensed consolidated financial statements.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Our Chief Executive Officer (who is our principal executive officer) and Chief Financial Officer (who is our principal financial officer), conducted an evaluation of the effectiveness of the design and operation 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, 2026.

Based on this evaluation, our principal executive officer and principal financial officer has concluded that during the quarter ended March 31, 2026, our disclosure controls and procedures were not effective due to the material weaknesses described below.

Management has identified material weaknesses in its internal control over financial reporting. A material weakness is a deficiency, or combination of deficiencies, in a company’s internal control over financial reporting such that there is a reasonable possibility that a material misstatement of its annual or interim financial statements will not be prevented or detected on a timely basis. The Company identified material weaknesses in its internal controls related to the Company related to: (1) the lack of a formalized control environment and oversite of controls over financial reporting and (2) having inadequate segregation of duties due to the size of the Company’s staff.

After identifying the material weaknesses, we have commenced our remediation efforts by taking the following steps:

We are in the process of designing formal written policies and procedures regarding internal controls over financial reporting.

We are increasing communication with our personnel and third-party professionals with whom we consult regarding complex accounting applications.

We are evaluating the need for additional qualified personnel.

Changes in Internal Control Over Financial Reporting

There was no change in our internal control over financial reporting that occurred during the most recent fiscal quarter that materially affected, or was reasonably likely to materially affect, our internal control over financial reporting.
