TRAWS PHARMA, INC.

Notes to Condensed Consolidated Financial Statements

1. Nature of Business

The Company

Traws Pharma, Inc. (“Traws Pharma” or the “Company”), formerly known as Onconova Therapeutics, Inc., was incorporated in the State of Delaware on December 22, 1998 and commenced operations on January 1, 1999. The Company’s headquarters are located in Newtown, Pennsylvania. On April 1, 2024, the Company acquired Trawsfynydd Therapeutics, Inc., a Delaware corporation (“Trawsfynydd”), through a merger (the “Merger”) and the name change to Traws Pharma was effected. The Company accounted for the transaction as an asset acquisition as substantially all of the fair value of the gross assets acquired was concentrated in two programs that were grouped as a single identifiable in-process research and development (“IPR&D”) asset. Traws Pharma is a clinical stage biopharmaceutical company dedicated to developing novel therapies to target critical threats to human health in respiratory viral diseases. Following the Merger, the Company has four clinical programs: (i) tivoxavir marboxil, an investigational oral, small molecule CAP-dependent endonuclease inhibitor designed to be administered as a single-dose for the treatment of bird flu and seasonal influenza; (ii) ratutrelvir, an inhibitor of the main protease (also known as 3CL protease) of the SARS-CoV-2 virus, the causative agent in COVID-19; (iii) narazaciclib (ON 123300), a multi-targeted kinase inhibitor in solid tumors and hematological malignancies as a single agent or in combination with other anti-cancer therapies; and (iv) rigosertib, administered alone or in combination for investigation in various cancers. The Company’s primary focus is the development of tivoxavir marboxil and ratutrelvir, and its strategic objective for narazaciclib and rigosertib is limited to business development activities—namely, seeking partnerships or out-licensing arrangements to enable their further development by third parties.  

Liquidity

The Company has incurred recurring operating losses since inception. As of June 30, 2026, the Company had an accumulated deficit of approximately $650,145,000. The Company anticipates that operating losses will continue for the foreseeable future due to, among other things, costs related to research, development of its product candidates and its clinical programs, strategic alliances and its administrative organization. At June 30, 2026, the Company had cash and cash equivalents of $5,016,000. Based on current projections, the Company believes that it does not have sufficient cash and cash equivalents to support its operations for more than one year following the date that these financial statements are issued. As a result of these conditions, substantial doubt exists about the Company’s ability to continue as a going concern.

The Company will require substantial additional financing to fund its ongoing clinical trials and operations, and to continue to execute its strategy. Management plans to explore various dilutive and non-dilutive sources of funding, including equity financings, strategic alliances, business development and other sources. The future success of the Company is dependent upon its ability to obtain additional funding. The failure to obtain sufficient capital on acceptable terms when needed would have a material adverse effect on the Company’s business, results of operations and financial condition. There can be no assurance, however, that the Company will be successful in obtaining such funding in sufficient amounts, on terms acceptable to the Company, or at all.

Due to the inherent uncertainty involved in making estimates and the risks associated with the research, development, and commercialization of biopharmaceutical products, the Company may have based this estimate on assumptions that may prove to be wrong, and the Company's operating plan may change as a result of many factors currently unknown to the Company.

The accompanying financial statements have been prepared on a going concern basis, which contemplates the realization of assets and satisfaction of liabilities in the normal course of business, and do not include any adjustments relating to recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might be necessary should the Company be unable to continue as a going concern.

2. Summary of Significant Accounting Policies

Basis of Presentation

The condensed consolidated financial statements are prepared in conformity with accounting principles generally accepted in the United States (“GAAP”) for interim financial information. Certain information and footnotes normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). The financial statements include the consolidated accounts of the Company and its wholly-owned subsidiaries: Trawsfynydd Therapeutics LLC, Trawsfynydd Therapeutics AU Ltd, Throxavir Therapeutics AU Pty Ltd and Onconova Europe GmbH. All significant intercompany transactions have been eliminated.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Management bases its estimates on historical experience and on various other market-specific and relevant assumptions that management believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets, liabilities, and equity and the amount of revenues and expenses. Actual results could differ significantly from those estimates. The most significant estimates and assumptions that management considers in the preparation of the Company's financial statements relate to prepaid and accrued research and development costs; the valuation of consideration transferred in acquiring the assets of Trawsfynydd; and inputs used in the Black-Scholes model for stock-based compensation expense and Series A Warrants (as defined below) liability.

Unaudited Interim Financial Information

The accompanying condensed consolidated balance sheet as of June 30, 2026, the condensed consolidated statements of operations and comprehensive (loss) income for the three and six months ended June 30, 2026 and 2025, the consolidated statements of convertible preferred stock and stockholders’ equity (deficit) for the three and six months ended June 30, 2026 and 2025 and the condensed consolidated statements of cash flows for the six months ended June 30, 2026 and 2025 are unaudited. The interim unaudited condensed consolidated financial statements have been prepared on the same basis as the annual audited consolidated financial statements and, in the opinion of management, reflect all adjustments, which include only normal recurring adjustments, necessary for the fair statement of the Company’s financial position as of June 30, 2026, the results of its operations for the three and six months ended June 30, 2026 and 2025, and its cash flows for the six months ended June 30, 2026 and 2025. The financial data and other information disclosed in these notes related to the three and six months ended June 30, 2026 and 2025 are unaudited. The results for the three and six months ended June 30, 2026 are not necessarily indicative of results to be expected for the year ending December 31, 2026, any other interim periods, or any future year or period.  These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto for the year ended December 31, 2025 included in the Company’s Annual Report on Form 10-K /A for the fiscal year ended December 31, 2025 (“Annual Report”), filed with the SEC on April 15, 2026.

Segment Information

Operating segments are defined as components of an enterprise about which separate discrete information is available for evaluation by the chief operating decision maker, or decision-making group, in deciding how to allocate resources in assessing performance. The Company has one operating segment. The Company’s chief operating decision maker (“CODM”) is the chief executive officer. The Company’s CODM manages the Company’s operations on a consolidated basis for the purpose of allocating resources. All the Company’s long-lived assets are held in the United States.

Table of Contents

Concentrations of Credit Risk and Off-Balance Sheet Risk

Financial instruments that potentially subject the Company to concentrations of credit risk are primarily cash and cash equivalents. The Company maintains a portion of its cash and cash equivalent balances in the form of money market accounts with financial institutions that management believes are creditworthy. The Company has no financial instruments with off-balance sheet risk of loss.

At June 30, 2026, the Company had $3,905,000 of its cash and cash equivalents in money market funds that invest in a portfolio of liquid, high-quality debt securities issued by the U.S. government.

Significant Accounting Policies

These interim condensed consolidated financial statements have been prepared in accordance with U.S. GAAP and SEC instructions for interim financial information, and should be read in conjunction with the Company's Annual Report. Significant accounting policies and other disclosures normally provided have been omitted since such items are disclosed in the Company's Annual Report. The Company uses the same accounting policies in preparing quarterly and annual financial statements.

Tax Incentive Receivable

The Company is eligible to receive a cash refund from the Australian Taxation Office for eligible research and development (“R&D”) expenditures under the Australian Research and Development Tax Incentive Program (the “Australian Tax Incentive”). The Australian Tax Incentive is recognized as a reduction to R&D expense when the relevant expenditure has been incurred, the amount can be reliably measured and the Australian Tax Incentive will be received. The Company’s Australian subsidiaries began operations in the second quarter of 2024, and the Company has recognized reductions to R&D expenses of $1,990,000 and $2,390,000 for the three and six months ended June 30, 2026, respectively, and $0 and $63,000 for the three and six months ended June 30, 2025, respectively.

Impairment of Definite Lived Intangible Assets

The Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If the carrying amount of the asset exceeds its estimated undiscounted net cash flows, before interest, the Company will recognize an impairment loss equal to the difference between its carrying amount and its estimated fair value. If impairment is recognized, the reduced carrying amount of the asset will be accounted for as its new cost. Generally, fair values are estimated using discounted cash flow, replacement cost or market comparison analyses. The process of evaluating impairment requires estimates as to future events and conditions, which are subject to varying market and economic factors. Therefore, it is reasonably possible that a change in an estimate resulting from judgments as to future events could occur which would affect the recorded amounts of the asset. No impairment losses were recorded for the three and six months ended June 30, 2026 or 2025.

Intangible Assets

Intangible assets consist entirely of patents. Costs related to patents, which include legal and application fees, are capitalized and amortized over the estimated useful lives using the straight-line method. Patent amortization commences once final approval of the patent has been obtained. For patents purchased in an asset acquisition, the useful life is determined largely by valuation estimates of remaining economic life. The Company’s patent, purchased in connection with the Purchased Assets from Viriom, Inc. has a useful life of 15 years.

Fair Value of Financial Instruments

The Company accounts for financial instruments under ASC 820, Fair Value Measurements (“ASC 820”). This statement defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles, and expands disclosures about fair value measurements. To increase consistency and comparability in fair value

11

Table of Contents

measurements, ASC 820 establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three levels as follows:

Level 1 — quoted prices (unadjusted) in active markets for identical assets or liabilities;

Level 2 — observable inputs other than Level 1, quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active, and model-derived prices whose inputs are observable or whose significant value drivers are observable; and

Level 3 — assets and liabilities whose significant value drivers are unobservable.

The carrying amounts reported in the accompanying consolidated financial statements for cash and cash equivalents, accounts payable, and accrued liabilities approximate their respective fair values because of the short-term nature of these accounts.

The following fair value hierarchy table presents information about the Company’s assets and liabilities measured at fair value on a recurring basis:

On December 29, 2024, the Company entered into a Securities Purchase Agreement with several investors for the sale of (i) up to 3,630,205 Class A Units (“Class A Units”), each Class A Unit consisting of (a) one share of common stock or one pre-funded warrant to initially purchase one share of common stock and (b) one Series A Warrant to purchase one share of common stock (“Series A Warrants”), and (ii) 289,044 Class B Units (the “Class B Units,” and, together with the Class A Units, the “Units”), each Class B Unit consisting of one pre-funded warrant and one Series A Warrant. The fair value of the pre-funded warrants is the intrinsic value of the pre-funded warrants due to their nominal exercise price. The fair value of the Series A Warrants was calculated using the Black-Scholes option pricing model and is revalued to fair value at the end of each reporting period until the earlier of the exercise or expiration of the Series A Warrants. The fair value of the Series A Warrant liability was estimated using the Black-Scholes option pricing model using the following assumptions:

The warrant liabilities were initially measured at fair value at the date of issuance and on a recurring basis. The changes in fair value of warrant liabilities will be recognized as part of the consolidated statements of operations. A summary of warrant liability activity for the three and six months ended June 30, 2026, is as follows:

Research and Development Expenses

R&D costs are charged to expense as incurred. These costs include, but are not limited to, license fees related to the acquisition of in-licensed products; employee-related expenses, including salaries, benefits and travel; expenses incurred under agreements with contract research organizations and investigative sites that conduct clinical trials and preclinical studies; the cost of acquiring, developing and manufacturing clinical trial materials; facilities, depreciation and other expenses, which include direct and allocated expenses for rent and maintenance of facilities, insurance and other supplies; and costs associated with preclinical activities and regulatory operations.

Costs for certain development activities, such as clinical trials, are recognized based on an evaluation of the progress to completion of specific tasks using data such as patient enrollment, clinical site activations, or information provided to the Company by its vendors with respect to their actual costs incurred. Payments for these activities are based on the terms of the individual arrangements, which may differ from the pattern of costs incurred, and are reflected in the consolidated financial statements as prepaid or accrued R&D expense, as the case may be.

Net (loss) income per share

For purposes of net (loss) income per share, the Company’s Series C Preferred shares have the same characteristics as common stock and have no liquidation or other material preferential rights over common stock and accordingly, have been considered as a second class of common stock in the computation of net (loss) income per share regardless of their legal form. (Losses) income are allocated between the common shares and the Series C Preferred on a pro rata basis, as they share equally in (losses) income and residual net assets on an as-converted basis.

Basic (loss) income per share of common stock is computed by dividing net (loss) income by the weighted-average number of shares of common stock outstanding during each period, including pre-funded warrants. The pre-funded warrants to purchase common stock with an exercise price of $0.01 per share are included in the calculation of basic and diluted net (loss) income per share as the exercise price is non-substantive and is virtually assured.

Diluted (loss) income per share of common stock includes the effect from the potential exercise or conversion of securities, such as stock options, unvested restricted stock units, and common stock warrants, which would result in the issuance of incremental shares of common stock, using the treasury stock method, and the potential shares of converted common stock associated with the Series C Preferred using the if-converted method. Potential common shares are excluded from the diluted per share calculation when their effect is anti-dilutive, including in periods of net loss or when inclusion does not result in a decrease in earnings per share.

5. Commitments and Contingencies

Litigation

In the normal course of business, the Company is from time to time named as a party to legal claims and actions. The Company records a loss contingency reserve for a legal proceeding when the potential loss is considered probable and can be reasonably estimated. The Company has not recorded any amounts for loss contingencies as of June 30, 2026.

On June 17, 2024, Steven M. Fruchtman informed the Board of his intent to resign from his positions as President and Chief Scientific Officer, Oncology and indicated to the Company that Dr. Fruchtman believed his resignation to be for “good reason” under the terms of his employment agreement and his expectation of compensation commensurate therewith and in connection with a change in control. The Board accepted Dr. Fruchtman’s resignation effective immediately but disagreed with the characterization of the events set forth in the letter. The claims were submitted to arbitration for resolution, and arbitration proceedings began in June 2026 with the American Arbitration Association. Following an evidentiary hearing held in June 2026, the arbitrator issued a Decision and Award on July 14, 2026. The arbitrator denied Mr. Fruchtman's claims for breach of contract and breach of the implied covenant of good faith and fair dealing, finding that Mr. Fruchtman did not have "Good Reason" to resign because his removal from the Board of Directors and the CEO position did not constitute a material breach of his employment agreements, and because he failed to prove

15

Table of Contents

that control of the Company changed immediately following the merger within the meaning of the applicable "Change in Control" definition. Accordingly, the arbitrator found that Mr. Fruchtman was not entitled to severance payments. In addition, the arbitrator denied Mr. Fruchtman's motion for discovery sanctions, finding that the Company's conduct did not warrant sanctions. As a result, the Company does not expect to incur any liability, including any severance or change in control payments, in connection with that matter, and no loss contingency has been recorded with respect to this matter as of June 30, 2026.

Contingent Value Rights

The Company issued CVRs to common stockholders as of April 15, 2024, and may be obligated to make future distributions to such CVR holders in connection with entering into strategic arrangements related to its oncology programs and/or future royalty payments related to the successful commercialization of such programs.

6. Convertible Preferred Stock and Stockholders’ Equity (Deficit)

At June 30, 2026, there were 6,737 shares of Series C Preferred stock outstanding. Certain material provisions of the Series C Preferred are as follows:

Conversion: Each share of Series C Preferred is convertible into 400 shares of Company common stock, subject to the Beneficial Ownership Limitation (as defined below).

Dividends: Shares of Series C Preferred participate in any dividends with common stockholders on an as-converted basis.

Liquidation: In the event of the liquidation, dissolution, or winding up of the affairs of the Company, whether voluntary or involuntary, the holders of Series C Preferred shall rank on parity with common stockholders as to the distributions of assets.

Beneficial Ownership Limitation: A holder of Series C Preferred is prohibited from converting its shares of Series C Preferred into shares of common stock if, as a result of such conversion, such holder, together with its affiliates, would beneficially own more than 19.9% of the total number of shares of Company common stock issued and outstanding immediately after giving effect to such conversion (the “Beneficial Ownership Limitation”).

At the Market Offering Agreement

On March 10, 2025, the Company entered into an At the Market Offering Agreement (the “ATM Agreement”) with Citizens JMP Securities, LLC (“Citizens”), pursuant to which the Company may offer and sell shares of its common stock, having an aggregate sales price of up to $50,000,000 (subject to certain limitations set forth in the ATM Agreement), from time to time, to or through Citizens, acting as sales agent and/or principal. During the three and six months ended June 30, 2026, the Company sold and issued 103,513 and 1,193,513 shares of its common stock, under the ATM Agreement for net proceeds of $119,000 and $1,918,000, respectively.

April 2026 Financing

On April 15, 2026, the Company entered into a Securities Purchase Agreement for a private placement (the “April 2026 Financing”), which closed on April 16, 2026. At closing, the Company issued 5,982,919 shares of its common stock (including 989,507 pre-funded warrants issued in lieu thereof) for aggregate upfront gross proceeds of approximately $10,000,000, at a purchase price of $1.6730 per share ($1.6630 per accompanying pre-funded warrant, each pre-funded warrant having an exercise price of $0.01). The Company also issued (i) April 2026 Series A Warrants to purchase up to 5,982,919 shares of common stock, (ii) April 2026 Series B Warrants to purchase up to 5,982,919 shares of common stock, and (iii) April 2026 Series C Warrants to purchase up to 17,948,757 shares of common stock, each with an exercise price of $1.673 per share, subject to adjustment. If all such warrants are exercised for cash, the Company will receive additional gross proceeds of approximately $50,000,000.

Table of Contents

The April 2026 Series A Warrants become exercisable upon the Company’s receipt of approval from the Medicines and Healthcare products Regulatory Agency (“MHRA”) to conduct a human challenge trial in the United Kingdom (“UK”). The April 2026 Series B Warrants become exercisable upon the later of the announcement of data from the human challenge trial or receipt of Shareholder Approval. The April 2026 Series C Warrants become exercisable upon receipt of Shareholder Approval, have a three-year term, and are subject to a forced-exercise provision under which, if the closing price of the Company’s common stock is at or above 200% of the exercise price for an uninterrupted period of 30 trading days, the Company may call for cancellation of the unexercised April 2026 Series C Warrants for consideration of $0.001 per underlying share. Each warrant is subject to a beneficial ownership limitation of 4.99% (9.99% at the holder’s election). As of June 30, 2026, none of the April 2026 Series A Warrants, April 2026 Series B Warrants or April 2026 Series C Warrants were exercisable.

The Company incurred placement agent fees and other offering costs in connection with the April 2026 Financing, including a cash fee equal to 6.0% of gross proceeds and reimbursement of certain placement agent expenses of up to $175,000, resulting in net proceeds of $9,390,000.

On July 8, 2026, at the Company’s 2026 Annual Meeting of Stockholders, the Company’s stockholders approved, in accordance with Nasdaq Listing Rule 5635(d), the issuance of shares of common stock upon exercise of the April 2026 Series B Warrants and April 2026 Series C Warrants issued in the April 2026 Financing (the “Shareholder Approval”). As a result of the Shareholder Approval, the April 2026 Series C Warrants became exercisable, and the April 2026 Series B Warrants will become exercisable upon the announcement of data from the human challenge trial.

Series A Warrants and Pre-funded Warrants

On February 18, 2025, the Company and certain of the purchasers of Units in the equity offering that closed on December 31, 2024 (the “December 2024 Offering”) entered into amendments to the Series A Warrants (the “Series A Warrant Amendment”), pursuant to which the Series A Warrants issued to such purchasers were amended to (i) increase the threshold for a change of control, for purposes of determining whether a Fundamental Transaction (as defined in the Series A Warrants) has occurred, from 50% of the outstanding common stock of the Company to greater than 50% of the outstanding common stock of the Company, (ii) revise the expected volatility rate to be applied for purposes of determining the Black-Scholes Value of the Series A Warrants to be utilized for calculating consideration payable to the holders of the Series A Warrants in connection with a Fundamental Transaction that is not within the Company’s control, and (iii) remove Section 3(h) of the Series A Warrants, which, under certain circumstances, provided for adjustments to the exercise price of the Series A Warrants in the event of a reverse stock split, stock consolidation, or a recapitalization or similar event involving the Company’s common stock based on the volume weighted average price of the Company’s common stock over the eleven trading day period commencing five trading days immediately preceding such event and the five trading days immediately following such event. The Series A Warrant Amendment resulted in the reclassification of $4,196,000 in warrant liability into permanent equity during the six months ended June 30, 2025.

During the first quarter of 2025, certain purchasers of Units in the December 2024 Offering exercised their pre-funded warrants for an aggregate of 1,382,559 shares of the Company’s common stock. On March 27, 2025,  the Company and those purchasers holding all pre-funded warrants outstanding as of such date entered into amendments to the pre-funded warrants (the “PFW Amendment”), pursuant to which the pre-funded warrants issued to such purchasers were amended to increase the threshold for a change of control, for purposes of determining whether a Fundamental Transaction (as defined in the pre-funded warrants) has occurred, from 50% of the outstanding common stock of the Company to greater than 50% of the outstanding common stock of the Company. The PFW Amendment and exercises of pre-funded warrants resulted in the reclassification of $11,631,000 in warrant liability into permanent equity during the six months ended June 30, 2025.

7. Warrants

Common stock warrants are accounted for in accordance with applicable accounting guidance provided in ASC Topic 815, Derivatives and Hedging - Contracts in Entity’s Own Equity (ASC Topic 815), as either derivative liabilities or as equity instruments depending on the specific terms of the warrant agreement. The conditions within ASC 815-40 are not subject to a probability assessment. The equity classified warrants do not fall under the liability criteria within ASC

480 Distinguishing Liabilities from Equity, as they are not puttable and do not represent an instrument that has a redeemable underlying security. The equity classified warrants do meet the definition of a derivative instrument under ASC 815, but are eligible for the scope exception as they are indexed to the Company’s own stock and would be classified in permanent equity if freestanding. All warrants granted during the six months ended June 30, 2026 were issued in connection with the April 2026 Financing described in Note 6.

8. Stock-Based Compensation

In 2021, the Company adopted its 2021 Incentive Compensation Plan, which was subsequently amended and restated in each of 2022 and 2024 (as amended and restated, the “2021 Plan”). Upon adopting the 2021 Plan, no further awards have been or will be made under the Company’s 2018 Omnibus Incentive Compensation Plan (the “2018 Plan”). Under the 2021 Plan, the Company may grant incentive stock options, non-qualified stock options, stock awards, stock units, stock appreciation rights and other stock-based awards to employees, non-employee directors, consultants, and advisors. At June 30, 2026, there were 113,300 shares available for future issuance with respect to new awards.

On July 8, 2026, at the Company’s 2026 Annual Meeting of Stockholders, the Company’s stockholders approved an amendment to the 2021 Plan to increase the number of shares of common stock available for issuance thereunder by 2,000,000 shares and to make certain other administrative changes.

Stock-based compensation expense includes stock options granted to employees and non-employees and has been reported in the Company’s unaudited condensed consolidated statements of operations and comprehensive loss in either R&D expenses or general and administrative expenses depending on the function performed by the optionee. No net tax benefits related to the stock-based compensation costs have been recognized since the Company’s inception. The Company recognized stock-based compensation expense related to stock options and restricted stock units (“RSUs”) as follows for the three and six months ended June 30, 2026, and 2025:

The Company accounts for all stock-based payments made to employees, non-employees and directors using an option pricing model for estimating fair value. Accordingly, stock-based compensation expense is measured based on the estimated fair value of the awards on the date of grant. Compensation expense is recognized for the portion that is ultimately expected to vest over the period during which the recipient renders the required services to the Company using the straight-line single option method.

The Company uses the Black-Scholes option-pricing model to estimate the fair value of stock options at the grant date. The Black-Scholes model requires the Company to make certain estimates and assumptions related to the expected price volatility of the common stock, the period during which the options will be outstanding, the rate of return on risk-free investments and the expected dividend yield for the Company’s stock.

As of June 30, 2026, there was $1,379,000 of unrecognized compensation expense related to the unvested stock options which is expected to be recognized over a weighted-average period of approximately 0.6 years.

The weighted-average assumptions underlying the Black-Scholes calculation of grant date fair value of stock options include the following:

The weighted-average valuation assumptions were determined as follows:

Risk-free interest rate: The Company based the risk-free interest rate on the interest rate payable on U.S. Treasury securities in effect at the time of grant for a period that is commensurate with the assumed expected option term.
Expected term of options: Due to its lack of sufficient historical data, the Company estimates the expected life of its employee stock options using the “simplified” method, as prescribed in Staff Accounting Bulletin (“SAB”) No. 107, whereby the expected life equals the arithmetic average of the vesting term and the original contractual term of the option.
Expected stock price volatility: Expected volatility is based on the historical volatility of the Company’s common stock.
Expected annual dividend yield: The Company has never paid, and does not expect to pay, dividends in the foreseeable future. Accordingly, the Company assumed an expected dividend yield of 0.0%.

Table of Contents

The Company grants RSUs to employees under the 2021 Plan, which typically have a vesting term of 33% on each of the first and second anniversaries, and 34% on the third anniversary of the date of grant. The compensation committee of the Board has approved RSU grants as inducement awards which vest 25% on each of the first four anniversaries of the date of grant. The Inducement RSUs were granted outside of the Company’s incentive plans in accordance with Nasdaq Listing Rule 5635(c)(4).

A summary of RSU activity for the six months ended June 30, 2026 is as follows:

At June 30, 2026, the unrecognized compensation cost related to unvested service-based RSUs was $393,000, which will be recognized over the remaining service period of 1.2 years.

Grants of PSUs and SARs

During 2020 and 2021, the compensation committee of the Board and the Board approved a cash bonus program of cash-settled stock appreciation right awards to the Company’s employees and non-employee directors, and cash-settled performance stock unit awards to the Company’s employees. These awards were granted outside of the Company’s 2018 Plan and the 2021 Plan. As the Company’s stock price has decreased since these awards were issued, their impact on the results of operations and balance sheet of the Company are not material during 2026 or 2025.

Overview

As of June 30, 2026, we had cash and cash equivalents of $5.0 million and an accumulated deficit of $650.1 million. We expect to incur significant expenses and operating losses for the foreseeable future as we continue the development of, and seek regulatory approval for, our product candidates, even if milestones under our license and collaboration agreements may be met. Based on current projections, we do not have sufficient cash and cash equivalents as of the date of this Quarterly Report to support our operations for at least the 12 months following the date that the condensed consolidated financial statements included herein are issued. Accordingly, substantial doubt exists with respect to our ability to continue as a going concern within one year after the date that such financial statements are issued.

We are exploring various sources of funding for development and applying for regulatory approval of our research compounds as well as for our ongoing operations. If we raise additional funds through strategic collaborations and alliances or licensing arrangements with third parties, which may include existing collaboration partners, we may have to relinquish valuable rights to our technologies or product candidates or grant licenses on terms that are not favorable to us. There can be no assurance, however, that we will be successful in obtaining such financing in sufficient amounts, on terms acceptable to us, or at all. In addition, there can be no assurance that we will obtain approvals necessary to market our product candidates or achieve profitability or sustainable, positive cash flow. If we are unable to successfully raise sufficient additional capital, through future financings or through strategic and collaborative arrangements, we will not have sufficient cash to fund our ongoing trials and operations.

Our Portfolio/ Product Candidates/ Compounds

We are a clinical-stage biopharmaceutical company aiming to address unmet medical needs in respiratory viral diseases and cancer. We have four clinical programs:

Tivoxavir marboxil, which we acquired as part of our 2024 merger with Trawsfynydd Therapeutics, Inc. (the “Merger”), is a small molecule cap-dependent endonuclease inhibitor. Cap-dependent endonuclease (“CEN”) is an enzyme that is important for influenza virus replication. Tivoxavir marboxil is intended to inhibit CEN and, thus, is intended to impede influenza virus replication including, the influenza A or B viral strains and bird flu viral strains. It is our intention to develop tivoxavir marboxil as an oral dose given only once for potential treatment and prophylaxis of bird flu and seasonal influenza.

The first-in-man clinical study of tivoxavir marboxil (designated AV5124 in a previous study) was performed from May to September of 2023 in Russia. The study sponsor was Pharmasyntez, JSC. We have the right to use the data resulting from the study outside of Russia and the Eurasian Economic Community countries. The trial was a single ascending dose study, and, as such, each study participant only received one dose of tivoxavir marboxil. The study consisted of four dose cohorts that received 20, 40, 80 or 120 mg tivoxavir marboxil delivered as 20 mg strength tablets, or placebo. The study enrolled 28 healthy males ages 18-45 years who received either the study drug or placebo. The primary study endpoint was measurement of the safety and tolerability of single drug doses in healthy volunteers. The secondary endpoint was the measurement of pharmacokinetic parameters of single drug doses in healthy volunteers on an empty stomach or after a meal. In the study, one subject who received a single 40 mg dose of the study drug, experienced two adverse events (“AEs”). This subject experienced hyperglycemia, which was deemed to be mild and believed probably related to tivoxavir marboxil, and erosive gastritis with complications in the form of severe iron deficiency anemia, which was considered to be a serious adverse event (“SAE”) believed unlikely to be related (doubtful per the protocol) to the study drug.

25

Table of Contents

There were no other AEs in the trial, including at higher doses. The pharmacokinetic measurements indicated a small food effect for tivoxavir marboxil, with increased exposure when the drug was taken after a meal but otherwise showed increasing exposure with increasing dose.

We advanced the development of tivoxavir marboxil with a Traws Pharma sponsored Phase 1 randomized, blinded, and placebo-controlled study in Australia that was approved by the Human Research Ethics Committee (“HREC”). This study enrolled four cohorts of 8 participants each, with 6 participants randomized to receive study drug and 2 participants assigned to receive placebo in each cohort. Participants were required to be healthy males or females ages 18-64 years. Participants took either one dose of the study drug or one dose of placebo. Dose levels evaluated in this study included 80, 120, 240 and 480 mg in capsules, taken orally. The primary endpoint of the study was the determination of safety and tolerability; the secondary and other endpoints included the determination of the drug pharmacokinetic profile. Topline data showed good overall tolerability and a pharmacokinetic profile that appears to support the potential use of tivoxavir marboxil as a one-time treatment for influenza. Sixteen AEs were recorded, of which three were reported as possibly related to study drug during the study; all were mild headaches. Topline data from this study showed that a single dose of tivoxavir marboxil maintained plasma drug levels consistently above the EC90 and within the predicted therapeutic window for more than 23 days. On March 21, 2025, we submitted a request for a meeting with the FDA to align on a path forward, including to seek guidance regarding the potential for accelerated approval utilizing the “Animal Rule” for further development of tivoxavir marboxil in the treatment of H5N1 bird flu. The FDA “Animal Rule” allows approval of therapeutic interventions in cases where there is a risk of severe disease and a controlled human trial would be unethical or infeasible. Our meeting request was granted, and we submitted our briefing package to the FDA on April 24, 2025. On May 27, 2025, we received written responses from the FDA for a Type B pre-Investigational New Drug Application meeting (“pre-IND”). The FDA provided feedback on development paths for potential approval of tivoxavir marboxil for bird flu and seasonal flu, including on the potential use of the Animal Rule. On June 30, 2025, we announced our submission of briefing materials for a Type D meeting to enable further FDA dialog on a potential path to accelerated approval for bird flu, as a follow up to the pre-IND FDA interactions.

In addition, on June 30, 2025, we announced our proposed Phase 2 dose-ranging, non-inferiority study, which will evaluate the effects of tivoxavir marboxil in patients with seasonal influenza. A separate single arm will evaluate the effects of tivoxavir marboxil in patients infected with H5N1 bird flu. The proposed study has been submitted for HREC review and, once initiated, is expected to enroll subjects in Australia and selected countries in Southeast Asia with high rates of human bird flu infections. During a Type D meeting, the FDA affirmed its position that clinical trial data, rather than reliance on the Animal Rule, is the registrational path for bird flu therapeutics. We have determined to defer the initiation of this study at this time due to the low immediate likelihood of successfully recruiting a Phase 2 study incorporating bird flu-infected subjects. However, we believe that recent approval of our Phase 2 bird flu/seasonal flu phase 2 protocol by Australian and South Korean regulatory authorities will allow us to quickly initiate a clinical study in either the Southern or Northern Hemispheres, respectively, should the incidence rate of bird flu increase. In January 2026, we announced plans to progress an additional indication for TXM as a monthly oral tablet for prophylaxis of seasonal influenza, supported by Phase 1 exposure observations from an earlier capsule formulation and formulation work indicating that a compressed tablet may provide extended coverage; we also announced that a time slot was secured for a human influenza prophylaxis human challenge trial targeted for June 2026, contingent on completion of a planned bridging healthy volunteer study. On June 12, 2026, we announced that the planned challenge study was deferred following a negative review of the program by the UK’s Medicines and Healthcare products Regulatory Agency ("MHRA"). On June 22, 2026, we announced that, based on further MHRA feedback, we are developing an updated toxicology data package that we expect to resubmit during the third quarter of 2026 to enable the study to proceed, with a formal MHRA response expected within 30 days of resubmission. There can be no assurance that the MHRA will accept the updated data package, that the challenge study will proceed, or as to the timing thereof. Separately, FDA informed the Company

26

Table of Contents

that its US IND for tivoxavir marboxil was being placed on clinical hold due to concerns with the toxicology data package. The Company is actively engaging with the FDA to address the clinical hold and is working to develop and submit a comprehensive response, with the goal of resolving the hold and advancing the program in the U.S. by the end of 2026.

Ratutrelvir (“TRX01”), which we acquired as part of the Merger, is an inhibitor of the main protease (also known as 3CL protease) of the SARS-CoV-2 virus, the causative agent in COVID-19. The main protease is an essential component in the mechanism for SARS-CoV-2 replication. TRX01 is intended to inhibit this protease and reduce SARS-CoV-2 virus replication. In vitro laboratory tests that measured the impact of TRX01 on SARS-CoV-2 replication, demonstrated that TRX01 inhibited the replication of viral isolates of the original SARS-CoV-2 isolates, and viral variants in the delta and omicron types. An animal study using the widely adopted K18 transgenic mouse model, demonstrated non-inferiority between TRX01 and the combination of nirmatrelvir + ritonavir, in terms of time to death and lung virus burden in this highly lethal model with neurological manifestations. Based on preclinical pharmacokinetic studies in multiple animal species, we intend to develop TRX01 for use without co-administration of a human cytochrome P450 (“CYP”) inhibitor such as ritonavir.

TRX01 was studied in a Phase 1 clinical trial that included single and multiple ascending dose phases. Participants were required to be healthy males or females ages 18-64 years. The primary endpoint of the study was the measurement of safety and tolerability, and the secondary endpoint included the determination of the drug pharmacokinetic and pharmacodynamic profiles. The Phase 1 trial was conducted in Australia. It was sponsored by the Company and was approved by HREC. The trial administered either the study drug or placebo to 40 participants in the single ascending dose phase, which included 5 cohorts with 8 participants in each cohort (6 received study drug and two received placebo). Subjects in the single ascending dose phase received one oral dose of the study drug or placebo, depending on their assigned group. The single ascending dose portion of the study assessed TRX01 at 15, 50, 150, 300 and 600 mg doses. Subjects in the multiple ascending dose phase received a daily single oral dose of 150 mg or 600 mg (6 active and 2 placebo) for 10 consecutive days. The study was completed in September 2024. There were few recorded AEs reported up to the highest dose, and none were determined to be related to study drug. Topline data from the study showed no treatment related AEs reported up to the highest dose. Topline data also showed that once-daily administration of TRX01 for 10 consecutive days maintained plasma drug levels within the predicted therapeutic window for 12 days.

On June 30, 2025, we announced our proposed Phase 2 non-inferiority study, which will evaluate the effects of ratutrelvir in newly diagnosed COVID-19 patients, and on August 18, 2025, we announced receipt of approval from the HREC to proceed with the Phase 2 study. The study is intended to enroll patients on a 10-day treatment regimen for ratutrelvir compared to the approved 5-day regimen for PAXLOVID®. In addition to efficacy and safety endpoints, the proposed study will also evaluate the rates of disease rebound as well as the incidence of Long COVID-19. On October 14, 2025, we announced the dosing of the first subject in our Phase 2 study to evaluate ratutrelvir. We intend to initiate a separate single arm to evaluate the safety and efficacy of ratutrelvir in newly diagnosed COVID-19 patients who are ineligible for treatment with PAXLOVID®. On December 17, 2025, we reported positive interim Phase 2 data showing ratutrelvir had a favorable tolerability profile versus PAXLOVID® and no viral rebound events were observed in ratutrelvir-treated patients, while a rebound occurred in the PAXLOVID®-arm. Interim results also showed activity in PAXLOVID® -eligible patients. On January 13, 2026, we reported interim data in a larger sample of 50 patients, suggesting faster time to sustained symptom resolution for ratutrelvir versus PAXLOVID®, continued no rebounds with ratutrelvir, and consistent safety/benefit signals in PAXLOVID®-eligible patients. On January 26, 2026, we announced the completion of enrollment of our ongoing 90-patient, open-label Phase 2 study of ratutrelvir versus PAXLOVID® in patients with mild-to-moderate COVID-19, together with a single arm in PAXLOVID®-ineligible subjects. In February 2026, we announced completion of the clinical analysis of the 90-patient, open-label Phase 2 study of ratutrelvir versus PAXLOVID®, together with a single arm in PAXLOVID®-ineligible subjects. We reported that

27

Table of Contents

completed clinical results confirmed a differentiated profile versus PAXLOVID® with fewer adverse events and no viral rebounds and equivalent time to sustained symptom resolution, and that results were recapitulated in PAXLOVID®-ineligible patients. In the PAXLOVID®-ineligible population specifically, we reported fewer treatment-related adverse events (3 events in 30 subjects; 10%) versus PAXLOVID® (7 events in 30 subjects; 23.3%) and faster symptom resolution compared to PAXLOVID® treatment (HR 1.31; 95% CI 0.78-2.20; p=0.018).

Narazaciclib is our oral CDK4-plus inhibitor intended initially to treat breast, endometrial and other cancers. Narazaciclib is a multi-targeted kinase inhibitor targeting multiple CDK’s, AMP-activated protein kinase (“AMPK”), related protein kinase 5 (“ARK5”), and colony-stimulating factor 1 receptor (“CSF1R”) at low nM concentrations, as well as other tyrosine kinases believed to drive tumor cell proliferation, survival and metastasis. We initiated a multi-center Phase 1/2a trial evaluating narazaciclib in combination with letrozole as a second or third-line therapy for recurrent metastatic low-grade endometrioid endometrial cancer in the first calendar quarter of 2023. In this study, both narazaciclib and letrozole were administered orally in the Phase 1 dose escalation phase. The first patient in this trial was dosed in May 2023 and the initial cohort (160 mg) was completed and no DLTs were observed. The 200 mg cohort enrolled 6 evaluable subjects, but two patients experienced dose limiting toxicities. As a result, the dose of narazaciclib of 160mg once daily in combination with letrozole 2.5mg once daily was declared to be the maximum tolerated dose and the recommended Phase 2 dose for women with low grade endometrioid endometrial cancer. This study is now closed to accrual. The database has been locked, and a clinical study report is final.

Another Phase 1 study of narazaciclib as a monotherapy has also been conducted in patients with relapsed and/or refractory advanced cancer. The objectives of this study were to assess the safety, tolerability, pharmacokinetics and pharmacodynamics of narazaciclib administered orally as escalating daily doses in patients with advanced cancer relapsed or refractory to at least 1 prior line of therapy. Narazaciclib was dosed on a continuous daily schedule in 28-day cycles. In this study, the highest dose tested was 280mg once daily given continuously. This study is now closed to accrual.

We do not intend to initiate further Company-sponsored development for narazaciclib and expect our activities to be limited primarily to (i) completing analysis and reporting from completed studies, (ii) maintaining intellectual property and other program-enabling documentation, and (iii) supporting business development efforts.

Rigosertib is our second asset in oncology. Rigosertib is currently being studied in investigator initiated trials for epidermolysis bullosa-associated squamous cell carcinoma. Both studies included the use of either IV or oral rigosertib, depending on the clinical need of the patient. This is due to GI obstruction arising as a result of the presence of esophageal strictures complicating oral administration or extreme skin fragility complicating IV administration. It is, therefore, important in these patients that the investigator has both dosing options for the appropriate dosing of their patients. The data presented here are preliminary and may be subject to change. Our objective for this program is limited to business development activities—namely, seeking partnerships or out-licensing arrangements to enable their further development by third parties.

Recent Developments

Influenza Program Regulatory Developments

On June 12, 2026, we announced that the planned test of tivoxavir marboxil in a Phase 2a human influenza challenge study had been deferred following a negative review of the program by the MHRA. On June 22, 2026, we announced that, based on further feedback and guidance from the MHRA, we are developing an updated toxicology data package that we expect to resubmit to the MHRA during the third quarter of 2026 to enable the study to proceed, with a formal MHRA response anticipated within 30 days of resubmission. Separately, the FDA informed us that our U.S. investigational new drug application for tivoxavir marboxil was placed on clinical hold. We are engaging with the FDA to

28

Table of Contents

address the clinical hold and intend to submit a comprehensive response, with the goal of resolving the hold and advancing the program in the United States.

There can be no assurance that the MHRA will accept the updated data package, that the FDA clinical hold will be resolved, that the affected studies will proceed, or as to the timing of any of the foregoing. See “—Our Portfolio/ Product Candidates/ Compounds” above and “Item 1A. Risk Factors” in Part II of our Annual Report for additional information regarding these developments and the related risks.

Arbitration Ruling

In July 2026, the arbitration proceeding relating to the claims asserted by Dr. Steven M. Fruchtman was resolved in our favor pursuant to a final award issued under the auspices of the American Arbitration Association, which denied in full the claims asserted against us. As a result, we do not expect to incur any liability, including any severance or change in control payments, in connection with that matter, and no loss contingency has been recorded with respect to this matter as of June 30, 2026. See Note 5, Commitments and Contingencies, to our unaudited condensed consolidated financial statements included in Part I of this Quarterly Report.

Nasdaq Compliance

On July 29, 2026, we received a notification letter from the Nasdaq Listing Qualifications Department of The Nasdaq Stock Market LLC (“Nasdaq”) notifying us that, because the closing bid price for our common stock was below $1.00 per share for at least 30 consecutive business days, we are not currently in compliance with the minimum bid price requirement for continued listing on The Nasdaq Capital Market, as set forth in Nasdaq Listing Rule 5550(a)(2) (the “Minimum Bid Price Requirement”). The notification has no immediate effect on the listing of the Company’s common stock on The Nasdaq Capital Market, and, therefore, the Company’s listing remains fully effective.

In accordance with Nasdaq Listing Rule 5810(c)(3)(A), we have a period of 180 calendar days from July 29, 2026 or until January 25, 2027, to regain compliance with the Minimum Bid Price Requirement. If at any time before January 25, 2027, the closing bid price of the Company’s common stock closes at or above $1.00 per share for a minimum of 10 consecutive business days (which may be extended to be a period of up to 20 consecutive business days at the discretion of Nasdaq), Nasdaq will provide written notification that we have regained compliance with the Minimum Bid Price Requirement, and the matter would be resolved. If we do not regain compliance during the compliance period ending on January 25, 2027, then Nasdaq may grant us a second 180 calendar day grace period to regain compliance, provided we (i) meet the continued listing requirement for market value of publicly held shares and all other initial listing standards for The Nasdaq Capital Market, with the exception of the Minimum Bid Price Requirement, and (ii) notify Nasdaq of our intent to cure the deficiency during the second compliance period.

We intend to continue actively monitoring the closing bid price for our common stock between now and January 25, 2027, and will consider available options to resolve the deficiency and regain compliance with the Minimum Bid Price Requirement. If we do not regain compliance within the allotted compliance period, including any extensions that may be granted by Nasdaq, Nasdaq will provide notice that our common stock will be subject to delisting. We would then be entitled to appeal that determination to a Nasdaq hearings panel. There can be no assurance that we will regain compliance with the Minimum Bid Price Requirement during the 180-day compliance period, secure a second period of 180 days to regain compliance, or maintain compliance with the other Nasdaq listing requirements.

On July 22, 2026, the SEC, acting under delegated authority, approved a Nasdaq rule change establishing a new continued listing requirement that companies maintain a Market Value of Listed Securities (“MVLS”) of at least $5 million, calculated as the consolidated closing bid price of a company’s common stock multiplied by the number of its listed securities. Unlike many other Nasdaq deficiencies, the standard would provide no cure or compliance period: a company whose MVLS remains below $5 million for 30 consecutive business days would become immediately subject to suspension and delisting, and a request for a hearing would not stay the suspension of trading. On July 29, 2026, following the filing of notices of intention to petition for SEC review, the approval order was automatically stayed under Rule 431(e) of the SEC’s Rules of Practice. Accordingly, the new MVLS requirement is not currently in effect, and there can be no assurance as to whether or when the stay will be lifted or the rule will become effective. If the stay is lifted and the rule

becomes effective, and if we fail to satisfy its requirements, Nasdaq may commence delisting procedures against the Company, regardless of the Company’s compliance with the Nasdaq Minimum Bid Price Requirement. See “Risk Factors – Failure to maintain compliance with Nasdaq’s continued listing requirements could result in delisting of our common stock” in Part II of this Quarterly Report.

General and administrative expenses increased by $1.8 million, or 106%, to $3.5 million for the three months ended June 30, 2026 from $1.7 million for the three months ended June 30, 2025.

Other operating income

Other operating income of $1.4 million consists of the removal of a legacy accrued research and development obligation, which was initially recognized in a prior reporting period. During the second quarter of 2026, we concluded that the accrued liability was no longer probable of settlement and that no future cash outflows related to the obligation were expected. Because the amount was originally recorded as research and development expense, its removal is presented within operating expenses rather than as non-operating income. No such income was recognized in the three months ended June 30, 2025.

Change in fair value of warrant liability

Change in fair value of warrant liability during the three months ended June 30, 2026 and 2025 was $0.2 million and $0.1 million, respectively.

Because the amount was originally recorded as research and development expense, its removal is presented within operating expenses rather than as non-operating income. No such income was recognized in the six months ended June 30, 2025.

Change in fair value of warrant liability

Change in fair value of warrant liability during the six months ended June 30, 2026 was $0.1 million. Change in fair value of warrant liability of $26.7 million during the six months ended June 30, 2025 represents the remeasurement of the warrant liability upon amendment of the pre-funded and Series A Warrants, whereas the previously liability-classified warrants were reclassified to permanent equity, the exercise of pre-funded warrants, and the remaining Series A Warrants as of June 30, 2025.

Liquidity and Capital Resources

As of June 30, 2026, we had cash and cash equivalents of $5.0 million, an accumulated deficit of $650.1 million, and a working capital deficit of $0.7 million. Since inception, we have experienced negative cash flows from our operations and expect to continue to incur significant expenses in connection with our ongoing activities.  

In April 2026, we completed the April 2026 Financing. The April 2026 Financing consisted of (i) $10.0 million of upfront gross proceeds at closing from the sale of shares of our common stock (or 989,507 pre-funded warrants in lieu thereof), (ii) a milestone-based warrant with an aggregate exercise price of $10.0 million that becomes exercisable upon receipt of approval from the MHRA to conduct the human challenge trial in the UK, (iii) a second milestone-based warrant with an aggregate exercise price of $10.0 million that becomes exercisable upon shareholder approval and the announcement of data from the human challenge trial and (iv) common warrants, subject to shareholder approval, with a three-year term to purchase shares of our common stock, providing potential additional gross proceeds of $30.0 million if fully exercised.

The milestone-based warrants become exercisable only upon achievement of the applicable milestone conditions, and there can be no assurance that we will receive any additional proceeds from the exercise of the milestone-based warrants or the common warrants, or as to the timing thereof. If we do not receive additional proceeds from the exercise of the warrants or obtain capital from other sources, we will need to raise additional capital to fund our operations and to satisfy our obligations as they become due.

Based on our current projections, as of the date of this Quarterly Report, we believe that our existing cash and cash equivalents, will not be sufficient to fund our operating requirements for at least the 12 months following the date

33

Table of Contents

that the consolidated financial statements included herein are issued. Accordingly, substantial doubt exists with respect to our ability to continue as a going concern within one year after the date that such financial statements are issued.

We will require substantial additional financing to fund our ongoing clinical trials and operations, and to continue to execute our strategy. There can be no assurance that we will be successful in obtaining such funding in sufficient amounts, on terms acceptable to us, or at all. The failure to obtain sufficient capital on acceptable terms when needed would have a material adverse effect on our business, results of operations, and financial condition.

The accompanying financial statements have been prepared on a going concern basis, which contemplates the realization of assets and satisfaction of liabilities in the normal course of business, and do not include any adjustments relating to recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might be necessary should we be unable to continue as a going concern.

Operating Activities

Net cash used in operating activities was $10.1 million for the six months ended June 30, 2026, which consisted of net loss of $10.2 million, partially offset by $1.5 million of non-cash charges primarily attributable to stock-based compensation. Significant changes in operating assets and liabilities included a decrease in accrued expenses related to the removal of our legacy accrued research and development obligation, which was partially offset by an increase in accounts payable due to timing of invoices and payments to our vendors and a decrease in receivables.

Net cash used in operating activities was $11.4 million for the six months ended June 30, 2025, which consisted of non-cash charges of $26.4 million primarily attributable to the change in fair value of warrant liability of $26.7 million and a $5.6 million change in operating assets and liabilities, partially offset by net income of $20.6 million. Significant changes in operating assets and liabilities included a net decrease in accounts payable, accrued expenses, and deferred revenue of $6.9 million due to timing of invoices and payments to our vendors, which was partially offset by net decreases in prepaid expenses and other assets and receivables of $1.3 million.

Financing Activities

Net cash provided by financing activities was $11.3 million for the six months ended June 30, 2026, attributable to $10.0 million of upfront proceeds from April 2026 Financing and $2.0 million of proceeds received from the sale of shares of our common stock under the At the Market Offering Agreement, dated March 10, 2025 by and between the Company and Citizens JMP Securities, LLC (the “ATM Agreement”), partially offset by the payment of offering costs.

Net cash provided by financing activities was $3.1 million for the six months ended June 30, 2025, and was attributable to the net proceeds received from the sale of shares of our common stock under the ATM Agreement and proceeds from exercised warrants, partially offset by the payment of offering costs.

Table of Contents

Material Cash Requirements

We have not achieved profitability since our inception and we expect to continue to incur net losses for the foreseeable future. We expect net cash expended in 2026 to be higher than 2025 due to clinical trials and increased headcount in our clinical and regulatory groups. We enter into contracts in the normal course of business with third-party contract organizations for clinical trials, preclinical studies, manufacturing and other services and products for operating purposes. These contracts generally provide for termination following a certain period after notice and therefore we believe that, currently, our non-cancelable obligations under these agreements are not material. Based on current projections, we believe that we do not have sufficient cash and cash equivalents to support our operations for more than one year following the date that these financial statements from this Quarterly Report are issued. These conditions raise substantial doubt about our ability to continue as a going concern through the one-year period after the date that the financial statements are issued.

We are exploring various sources of funding for continued development and any potential in-licensed compounds as well as our ongoing operations. We expect to incur significant expenses and operating losses for the foreseeable future as we continue the development and clinical trials of, and seek regulatory approval for, our product candidates, even if milestones under our license and collaboration agreements may be met. If we obtain regulatory approval for any of our product candidates, we expect to incur significant NDA preparation and commercialization expenses. We do not currently have a relationship with an organization for the sales, marketing and distribution of pharmaceutical products. In the future, we may rely on licensing and co-promotion agreements with strategic or collaborative partners for the commercialization of our products in the United States and other territories. If we choose to build a commercial infrastructure to support marketing in the United States for any of our product candidates that achieve regulatory approval, such commercial infrastructure could be expected to include a targeted, oncology sales force supported by sales management, internal sales support, an internal marketing group and distribution support. To develop the appropriate commercial infrastructure internally, we would have to invest financial and management resources, some of which would have to be deployed prior to having any certainty about marketing approval. Furthermore, we have and expect to continue to incur additional costs associated with operating as a public company.

For additional risks, please see “Risk Factors” in Part II of this Quarterly Report and previously disclosed in our Annual Report. 

Critical Accounting Policies and Estimates

This Management’s Discussion and Analysis of our Financial Condition and Results of Operations is based on our interim unaudited condensed consolidated financial statements, which have been prepared in accordance with GAAP. The preparation of our financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses and the disclosure of contingent assets and liabilities in our consolidated financial statements. On an ongoing basis, we evaluate our estimates and judgments, including those related to accrued expenses, stock-based compensation, and the contingent value rights. We base our estimates on historical experience, known trends and events and various other factors that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. As of June 30, 2026, there have been no significant changes in our critical accounting policies and estimates as discussed in our Annual Report.

As a smaller reporting company, the Company is not required to provide the information otherwise required by this Item.

Item 4. Controls and Procedures

Management’s Evaluation of our Disclosure Controls and Procedures

Our management, with the participation of our principal executive and principal financial officers, evaluated the effectiveness of our disclosure controls and procedures as of June 30, 2026. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) promulgated under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure. Based on the evaluation of our disclosure controls and procedures as of June 30, 2026, our principal executive and principal financial officers concluded that, as of such date, our disclosure controls and procedures were effective.  

Inherent Limitations on Effectiveness of Controls

Our management, including our principal executive and principal financial officers, does not expect that our disclosure controls and procedures or our internal control over financial reporting will prevent or detect all errors and all fraud. A control system, no matter how well-designed and operated, can provide only reasonable, not absolute, assurance that the control system’s objectives will be met. The design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Further, because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud, if any, have been detected. The design of any system of controls is based in part on certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Projections of any evaluation of the effectiveness of controls to future periods are subject to risks. Over time, controls may become inadequate because of changes in conditions or deterioration in the degree of compliance with policies or procedures.

Changes in Internal Control Over Financial Reporting

There were no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during the fiscal quarter ended June 30, 2026 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 a description of our material pending legal proceedings, please see Note 5, Commitments and Contingencies, to our unaudited condensed consolidated financial statements included in Part I of this Quarterly Report. We may, in the ordinary course of business, face various claims brought by third parties, and we may, from time to time, make claims or take legal actions to assert our rights, including intellectual property rights as well as claims relating to employment matters and the safety or efficacy of our products. Any of these claims could subject us to costly litigation. If this were to happen, the payment of any such awards could have a material adverse effect on our business, financial condition and results of operations. Additionally, any such claims, whether or not successful, could damage our reputation and business.

Item 1A. Risk Factors

In addition to the other information set forth in this Quarterly Report, you should carefully consider the risk factors discussed in Part I, “Item 1A.  Risk Factors” in our Annual Report and in other reports filed with the SEC, which could materially affect our business, financial condition or future results. The risks described in our Annual Report are not

36

Table of Contents

the only risks we face.  Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition and/or operating results.

Except as set forth below, there have not been any material changes to the risk factors disclosed in the Annual Report.

If our stock price continues to remain below $1.00, our common stock may be subject to delisting from The Nasdaq Capital Market, which would materially reduce the liquidity of our common stock and have an adverse effect on our market price.

On July 29, 2026, we received a notification letter from Nasdaq notifying us that, because the closing bid price for our common stock was below $1.00 per share for at least 30 consecutive business days, we are not currently in compliance with the Minimum Bid Price Requirement for continued listing on The Nasdaq Capital Market. The notification has no immediate effect on the listing of the Company’s common stock on The Nasdaq Capital Market, and, therefore, the Company’s listing remains fully effective.

In accordance with Nasdaq Listing Rule 5810(c)(3)(A), we have a period of 180 calendar days from July 29, 2026 or until January 25, 2027, to regain compliance with the Minimum Bid Price Requirement. If at any time before January 25, 2027, the closing bid price of the Company’s common stock closes at or above $1.00 per share for a minimum of 10 consecutive business days (which may be extended to be a period of up to 20 consecutive business days at the discretion of Nasdaq), Nasdaq will provide written notification that we have regained compliance with the Minimum Bid Price Requirement, and the matter would be resolved. If we do not regain compliance during the compliance period ending on January 25, 2027, then Nasdaq may grant us a second 180 calendar day grace period to regain compliance, provided we (i) meet the continued listing requirement for market value of publicly held shares and all other initial listing standards for The Nasdaq Capital Market, with the exception of the Minimum Bid Price Requirement, and (ii) notify Nasdaq of our intent to cure the deficiency during the second compliance period.

We intend to continue actively monitoring the closing bid price for our common stock between now and January 25, 2027, and will consider available options to resolve the deficiency and regain compliance with the Minimum Bid Price Requirement. If we do not regain compliance within the allotted compliance period, including any extensions that may be granted by Nasdaq, Nasdaq will provide notice that our common stock will be subject to delisting. We would then be entitled to appeal that determination to a Nasdaq hearings panel. There can be no assurance that we will regain compliance with the Minimum Bid Price Requirement during the 180-day compliance period, secure a second period of 180 days to regain compliance, or maintain compliance with the other Nasdaq listing requirements.

We are currently evaluating our alternatives to resolve the listing deficiency. To the extent that we are unable to resolve the listing deficiency, there is a risk that our common stock may be delisted from Nasdaq, which would adversely impact liquidity of our common stock, potentially result in even lower bid prices for our common stock, and make it more difficult for us to obtain financing through the sale of our common stock.

If we elect to implement a reverse stock split to regain compliance with the Nasdaq continued listing requirements, such reverse stock split could have a materially adverse effect on our business.

In the event that we are unable to regain compliance with the Minimum Bid Price Requirement through other methods, we may be required to implement a reverse stock split in order to do so. There are a number of risks associated with implementing a reverse stock split, including, without limitation:

The market price per share of our common stock post-reverse stock split may not remain in excess of the $1.00 minimum bid price per share, as required by Nasdaq, or we may fail to meet the other requirements for continued listing on Nasdaq, including the minimum value of listed securities, resulting in the delisting of our common stock from The Nasdaq Capital Market;
the reverse stock split may not result in a price per share that will successfully attract certain types of investors, and such resulting share price may not satisfy the investing guidelines of institutional investors or investment funds;

37

Table of Contents

the trading liquidity of the shares of our common stock may not improve, or may decline, as a result of the reverse stock split and there can be no assurance that the reverse stock split, if completed, would result in the intended benefits;
a reverse stock split could be viewed negatively by the market and other factors, which may adversely affect the market price of our common stock.

There can be no assurances that implementation of a reverse stock split would allow us to prevent the delisting of our common stock, and it could have a materially adverse effect on our business.

Failure to maintain compliance with Nasdaq’s continued listing requirements could result in the delisting of our common stock.

On July 22, 2026, the SEC, acting under delegated authority, approved a Nasdaq rule change establishing a new continued listing requirement that companies maintain a MVLS of at least $5 million, calculated as the consolidated closing bid price of a company's common stock multiplied by the number of its listed securities. Unlike many other Nasdaq deficiencies, the standard would provide no cure or compliance period: a company whose MVLS remains below $5 million for 30 consecutive business days would become immediately subject to suspension and delisting, and a request for a hearing would not stay the suspension of trading. On July 29, 2026, following the filing of notices of intention to petition for SEC review, the approval order was automatically stayed under Rule 431(e) of the SEC's Rules of Practice, and the new MVLS requirement is therefore not currently effective; we cannot predict whether, when, or in what form it may become effective. If the requirement becomes effective in its current or a similar form, we may face a heightened risk of delisting, particularly in light of the recent trading price of our common stock and our existing non-compliance with the Minimum Bid Price Requirement, and any resulting suspension or delisting would materially reduce the liquidity of our common stock, adversely affect its market price, and make it more difficult for us to raise capital, any of which could have a material adverse effect on our business, financial condition and results of operations
