(the “Company”) is a clinical stage biopharmaceutical company focused on the development and commercialization of novel immune-oncology products based on our proprietary Tri-specific Killer Engager (“TriKE®”), and Tetra-specific Killer Engager (“Dual Targeting TriKE®”) platforms. The Company’s TriKE® and Dual Targeting TriKE® platforms generate proprietary therapeutics designed to harness and enhance the cancer killing abilities of a patient’s own natural killer cells (“NK cells”). The corporate predecessor of GT Biopharma, Inc, Diagnostic Data, Inc., was incorporated in the state of California in 1965. Diagnostic Data, Inc. changed its incorporation to the state of Delaware on December 21, 1972 and changed its name to DDI Pharmaceuticals, Inc. on March 11, 1985. On September 7, 1994, DDI Pharmaceuticals, Inc. merged with International BioClinical, Inc. and Bioxytech S.A. and changed its name to OXIS International, Inc. On July 17, 2017, OXIS International, Inc. changed its name to GT Biopharma, Inc. Throughout this Quarterly Report on Form 10-Q, the terms “GTBP,” “we,” “us,” “our,” “the Company” and “our Company” refer to GT Biopharma, Inc.

All other trademarks, registered marks and trade names appearing herein are the property of their respective holders. Going Concern Analysis The accompanying unaudited condensed financial statements have been prepared assuming that the Company will continue as a going concern. The Company does not have any product candidates approved for sale and has not generated any revenue from its product sales. The Company has sustained operating losses since inception, and expects such losses to continue into the foreseeable future. Historically, the Company has financed its operations through public and private sales of common stock, $0.001 par value per share (the “Common Stock”), issuances of preferred stock and Common Stock, issuances of convertible debt instruments, and strategic collaborations. For the six months ended June 30, 2026, the Company recorded a net loss of approximately $7.4 million and used cash in operations of approximately $6.7 million. These factors raise substantial doubt about the Company’s ability to continue as a going concern within one year of the date that the financial statements are issued. In addition, the Company’s independent registered public accounting firm, in its report on the Company’s December 31, 2025 financial statements, raised substantial doubt about the Company’s ability to continue as a going concern. The financial statements do not include any adjustments that might be necessary if the Company is unable to continue as a going concern. The unaudited condensed financial statements do not include any adjustments that might be necessary if the Company is unable to continue as a going concern. Accordingly, the unaudited condensed financial statements have been prepared on the basis that assumes the Company will continue as a going concern and which contemplates the realization of assets and satisfaction of liabilities and commitments in the ordinary course of business. The Company has evaluated the significance of the uncertainty regarding the Company’s financial condition in relation to its ability to meet its obligations, which has raised substantial doubt about the Company’s ability to continue as a going concern. While it is very difficult to estimate the Company’s future liquidity requirements, the Company believes if it is unable to obtain additional financing, existing cash resources will not be sufficient to enable it to fund the anticipated level of operations through one year from the date the accompanying unaudited condensed financial statements are issued. There can be no assurances that the Company will be able to secure additional financing on acceptable terms. In the event the Company does not secure additional financing, the Company will be forced to delay, reduce, or eliminate some or all of its discretionary spending, which could adversely affect the Company’s business prospects, ability to meet long-term liquidity needs and the ability to continue operations.

Note 2 – Summary of Significant Accounting Policies Basis of Presentation The accompanying condensed financial statements are unaudited. These unaudited interim condensed financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Certain information and note disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. Accordingly, these unaudited interim condensed financial statements should be read in conjunction with the financial statements and notes thereto contained in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2025 filed with the SEC on March 2, 2026 (the “2025 Annual Report”). The balance sheet as of December 31, 2025 included herein, was derived from the audited financial statements as of that date. In the opinion of management, the accompanying unaudited condensed financial statements contain all adjustments necessary to fairly present the Company’s financial position and results of operations for the interim periods reflected. Except as noted, all adjustments contained herein are of a normal recurring nature. Results of operations for the fiscal periods presented herein are not necessarily indicative of fiscal year-end results. Accounting Estimates The preparation of financial statements in conformity with GAAP requires 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 financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Significant estimates include management’s estimates for continued liquidity, accruals for potential liabilities, assumptions used in deriving the fair value of warrant liabilities, valuation of equity instruments issued for debt and services and realization of deferred tax assets. Cash Equivalents The Company considers highly liquid investments with maturities of three months or less at the date of acquisition as cash equivalents in the accompanying unaudited condensed financial statements. At June 30, 2026 and December 31, 2025, total cash equivalents which consist of money market funds and treasuries with maturities of three months or less, amounted to approximately $4.7 million and $3.9 million, respectively. Restricted Cash As of June 30, 2026, the Company has classified certain cash balances as restricted cash in its unaudited condensed balance sheets. The Company’s restricted cash is deposited in a financial institution and held as a collateral for a credit card agreement with the same financial institution. Deferred Offering Costs The Company capitalizes the fair value of equity instruments granted and certain legal, accounting and other third-party fees that are directly related to the Company’s in-process equity financings until such financings are consummated. After consummation of an equity financing, these costs are recorded in stockholders’ equity as a reduction of additional paid-in capital generated as a result of the offering. Should a planned equity financing be abandoned, terminated or significantly delayed, the deferred offering costs are immediately written off to operating expenses. As of June 30, 2026, there was $507,000 of deferred offering costs on the balance sheet. Stock-Based Compensation The Company periodically issues stock-based compensation to officers, directors, employees, and consultants for services rendered. Such issuances vest and expire according to terms established at the issuance date. Stock-based payments to officers, directors, employees, and consultants in exchange for goods and services, which include grants of employee stock options, are recognized in the financial statements based on their grant date fair values in accordance with ASC 718, Compensation-Stock Compensation. Stock based payments to officers, directors, employees, and consultants, which are generally time vested, are measured at the grant date fair value and depending on the conditions associated with the vesting of the award, compensation cost is recognized on a straight-line or graded basis over the vesting period. Recognition of compensation expense for non-employees is in the same period and manner as if the Company had paid cash for the services. The fair value of stock options granted is estimated using the Black-Scholes option-pricing model, which uses certain assumptions related to risk-free interest rates, expected volatility, expected life, and future dividends. The assumptions used in the Black-Scholes option pricing model could materially affect compensation expense recorded in future periods. Research and Development Expenses Costs incurred for research and development are expensed as incurred. The salaries, benefits, and overhead costs of personnel conducting research and development of the Company’s products are included in research and development expenses. Purchased materials that do not have an alternative future use are also expensed. Purchased materials that have an alternative future are classified as a prepaid expense and periodically reviewed. Net Loss Per Share Basic earnings (loss) per share is computed using the weighted-average number of common shares outstanding during the period. Diluted earnings (loss) per share is computed using the weighted-average number of common shares and the dilutive effect of contingent shares outstanding during the period. Potentially dilutive contingent shares, which primarily consist of stock issuable upon exercise of stock options and warrants, and the conversion of Series L 10% Convertible Preferred Stock (the “Series L Preferred Stock”), have been excluded from the diluted loss per share calculation because their effect is anti-dilutive. During the six months ended June 30, 2026, the Company recorded dividends on Series L Preferred Stock of $177,000, which has been deducted from net income to arrive at net income attributable to Common Stockholders for the purpose of calculating basic and diluted earnings per share. <p id="xdx_896_eus-gaap--ScheduleOfAntidilutiveSecuritiesExcludedFromComputationOfEarningsPerShareTextBlock_zCNCsLZpdf3h" style="font: 10pt Times New Roman, Times, Serif;

The balances held at this financial institution at times may be in excess of Federal Deposit Insurance Corporation (“FDIC”) insurance limits of up to $250,000. Management believes that the financial institutions that hold the Company’s cash are financially sound and, accordingly, minimal credit risk exists. Segment Information The Company’s Chief Executive Officer and President (“CEO”) is our chief operating decision maker (“CODM”) and evaluates performance and makes operating decisions about allocating resources based on financial data presented on a consolidated basis. Because our CODM evaluates financial performance on a consolidated basis, the Company has determined that it operates as a single reportable segment composed of the financial results of the Company. Recent Accounting Pronouncements In November 2024, the FASB issued ASU 2024-03, Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, requiring public entities to disclose additional information about specific expense categories in the notes to the financial statements on an interim and annual basis. ASU 2024-03 is effective for fiscal years beginning after December 15, 2026, and for interim periods beginning after December 15, 2027, with early adoption permitted. The Company is currently evaluating the impact of adopting ASU 2024-03. The Company’s management has evaluated all the recently issued, but not yet effective, accounting standards and guidance that have been issued or proposed by the FASB or other standards-setting bodies through the filing date of these financial statements and does not believe the future adoption of any such pronouncements will have a material effect on the Company’s financial position and results of operations.

Stock-Based Compensation The Company periodically issues stock-based compensation to officers, directors, employees, and consultants for services rendered. Such issuances vest and expire according to terms established at the issuance date. Stock-based payments to officers, directors, employees, and consultants in exchange for goods and services, which include grants of employee stock options, are recognized in the financial statements based on their grant date fair values in accordance with ASC 718, Compensation-Stock Compensation. Stock based payments to officers, directors, employees, and consultants, which are generally time vested, are measured at the grant date fair value and depending on the conditions associated with the vesting of the award, compensation cost is recognized on a straight-line or graded basis over the vesting period. Recognition of compensation expense for non-employees is in the same period and manner as if the Company had paid cash for the services. The fair value of stock options granted is estimated using the Black-Scholes option-pricing model, which uses certain assumptions related to risk-free interest rates, expected volatility, expected life, and future dividends. The assumptions used in the Black-Scholes option pricing model could materially affect compensation expense recorded in future periods.

Research and Development Expenses Costs incurred for research and development are expensed as incurred.

Purchased materials that do not have an alternative future use are also expensed. Purchased materials that have an alternative future are classified as a prepaid expense and periodically reviewed.

Net Loss Per Share Basic earnings (loss) per share is computed using the weighted-average number of common shares outstanding during the period. Diluted earnings (loss) per share is computed using the weighted-average number of common shares and the dilutive effect of contingent shares outstanding during the period. Potentially dilutive contingent shares, which primarily consist of stock issuable upon exercise of stock options and warrants, and the conversion of Series L 10% Convertible Preferred Stock (the “Series L Preferred Stock”), have been excluded from the diluted loss per share calculation because their effect is anti-dilutive. During the six months ended June 30, 2026, the Company recorded dividends on Series L Preferred Stock of $177,000, which has been deducted from net income to arrive at net income attributable to Common Stockholders for the purpose of calculating basic and diluted earnings per share. <p id="xdx_896_eus-gaap--ScheduleOfAntidilutiveSecuritiesExcludedFromComputationOfEarningsPerShareTextBlock_zCNCsLZpdf3h" style="font: 10pt Times New Roman, Times, Serif;

Recent Accounting Pronouncements In November 2024, the FASB issued ASU 2024-03, Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, requiring public entities to disclose additional information about specific expense categories in the notes to the financial statements on an interim and annual basis. ASU 2024-03 is effective for fiscal years beginning after December 15, 2026, and for interim periods beginning after December 15, 2027, with early adoption permitted. The Company is currently evaluating the impact of adopting ASU 2024-03. The Company’s management has evaluated all the recently issued, but not yet effective, accounting standards and guidance that have been issued or proposed by the FASB or other standards-setting bodies through the filing date of these financial statements and does not believe the future adoption of any such pronouncements will have a material effect on the Company’s financial position and results of operations.

Note 3 – Stockholders’ Equity (Deficit) The Company’s authorized capital as of June 30, 2026 was 250,000,000 shares of Common Stock, par value $0.001 per share, and 15,000,000 shares of preferred stock, par value $0.01 per share. 2025 Private Placement of Equity Facility (the “Committed Equity Facility”) On May 14, 2025, and as amended on June 10, 2025, the Company entered into a common shares purchase agreement (the “Common Shares Purchase Agreement”) with investors (collectively, the “Investors”) relating to the Committed Equity Facility. Pursuant to the Common Shares Purchase Agreement, the Company has the right from time to time at its option to sell to the Investors up to $20 million of its Common Stock subject to certain conditions and limitations set forth in the Common Shares Purchase Agreement. Sales of the shares of Common Stock to the Investors under the Common Shares Purchase Agreement, and the timing of any sales, will be determined by the Company from time to time in its sole discretion and will depend on a variety of factors, including, among other things, market conditions, the trading price of the Common Stock and determinations by the Company regarding the use of proceeds from the sale of such shares of Common Stock. The net proceeds from any sales under the Common Shares Purchase Agreement will depend on the frequency with, and prices at, which the shares of Common Stock are sold to the Investors. The purchase price of the shares of Common Stock that the Company elects to sell to the Investors pursuant to the Common Shares Purchase Agreement will be <span id="xdx_903_ecustom--WeightedAverageVolumePriceOfCommonStockPercentage_pid_dp_uPure_c20250514__20250514__us-gaap--TypeOfArrangementAxis__custom--PurchaseAgreementMember_zP0hFYrCUUqj" title="Weighted average volume price of common stock percentage">93% of the volume weighted average price of the shares of Common Stock during the applicable purchase date on which the Company has timely delivered written notice to the Investors directing it to purchase shares of Common Stock under the Common Shares Purchase Agreement. In connection with the execution of the Common Shares Purchase Agreement, the Company agreed to issue to the Investors pre-funded warrants to purchase an aggregate of <span id="xdx_908_eus-gaap--ClassOfWarrantOrRightNumberOfSecuritiesCalledByWarrantsOrRights_iI_c20250514__us-gaap--TypeOfArrangementAxis__custom--PurchaseAgreementMember_zvy7sOc9oGU5" title="Warrants to purcahse">300,000 shares of Common Stock as consideration for their irrevocable commitment to purchase the shares of Common Stock upon the terms and subject to the satisfaction of the conditions set forth in the Common Shares Purchase Agreement. 2025 Warrant Inducement Transaction On February 26, 2025, the Company received gross proceeds of $686,000 before deducting placement agent fees and other offering expenses of $70,000 in relation to a warrant exercise inducement agreement with certain holders of existing warrants. The existing warrants were exercisable into 302,069 shares of Common Stock at $4.35 per share. The holders agreed to exercise these existing warrants at a reduced exercise price of $2.27 per share in exchange for the Company’s agreement to issue the holders new warrants (the “Inducement Warrants”) exercisable for an aggregate of up to <span id="xdx_907_eus-gaap--ClassOfWarrantOrRightNumberOfSecuritiesCalledByWarrantsOrRights_iI_c20250226__us-gaap--StatementEquityComponentsAxis__custom--InducementWarrantsMember_z2LUoBeWXtZe" title="Issuance of warrants">604,138 shares of Common Stock.

In addition, the Company issued warrants to the placement agent to purchase 21,145 shares of Common Stock at $2.8375 per share exercisable immediately upon issuance with a term of five years from the date of issuance. The Company determined that under ASC 815, the 2025 inducement and placement agent warrants are considered indexed to the Company’s own stock and eligible for an exception from derivative accounting. Accordingly, the fair value of the 2025 inducement and placement agent warrants are classified as equity. The Company recognized the aggregate effect of the modification of warrants and grant of inducement warrants of $1.1 million as an equity issuance cost and the accounting effect is recognized in the Statement of Stockholders’ Equity (Deficit). Preferred Stock Series C Preferred Stock As of June 30, 2026, there were <span id="xdx_908_eus-gaap--PreferredStockSharesOutstanding_iI_pid_c20260630__us-gaap--StatementClassOfStockAxis__us-gaap--SeriesCPreferredStockMember_zxBdzIFmC5v8" title="Preferred stock, shares outstanding">96,230 shares of series C preferred stock, par value $0.01 per share (the “Series C Preferred Stock”) issued and outstanding. As a result of numerous reverse stock-splits in previous years and the agreement terms for adjusting the rights of the related shares, the 96,230 shares of Series C Preferred Stock are convertible into an infinitesimal amount of Common Stock, have no voting rights, and in the event of liquidation, the holders of the Series C Preferred Stock would not participate in any distribution of the assets or surplus funds of the Company. The holders of Series C Preferred Stock also are not currently entitled to any dividends if and when declared by the Board of Directors (the “Board”). No dividends to holders of the Series C Preferred Stock were declared or unpaid through June 30, 2026. Series L Preferred Stock and Warrants The Company previously issued shares of Series L Preferred Stock and related warrants (the “2025 Warrants”) pursuant to a securities purchase agreement entered into in May 2025, as more fully described in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025.

The reduction in the conversion price constituted a dilutive issuance under the terms of the 2025 Warrants. Accordingly, the exercise price of the outstanding 2025 Warrants was reduced, and the number of shares underlying the 2025 Warrants was increased, such that the aggregate exercise price of the 2025 Warrants remained unchanged. For the six months ended June 30, 2026, the incremental change in the fair value of equity classified instruments upon the reduction of conversion and exercise prices was determined to be $433,000, and was treated as a deemed dividend. Dividends During the six months ended June 30, 2026, the Company declared and paid dividends of approximately $177,000 to holders of Series L Preferred Stock, which were settled through the issuance of <span id="xdx_90C_ecustom--StockIssuedDuringPeriodSharesDividends_c20260101__20260630__us-gaap--StatementClassOfStockAxis__custom--SeriesLPreferredStockMember_zPLyvmKqdi0g" title="Shares issued for dividends">442,764 shares of Common Stock.

Note 5 – Commitments and Contingencies Litigation The Company is involved in certain legal proceedings that arise from time to time in the ordinary course of our business. Except for income tax contingencies, we record accruals for contingencies to the extent that our management concludes that the occurrence is probable and that the related amounts of loss can be reasonably estimated. Legal expenses associated with the contingency are expensed as incurred. There is no current or pending litigation of any significance with the exception of the matters identified below that have arisen under, and are being handled in, the normal course of business: Ohri Matter On July 22, 2024, the Company filed an AAA Arbitration Demand against Manu Ohri, its former Chief Financial Officer. In the demand, the Company asserts claims against Mr. Ohri for breach of his fiduciary duties and breach of contract and seeks a declaratory judgment providing that the Company may characterize Mr. Ohri’s termination as “for cause” under his employment agreement, and that the Company may revoke the separation agreement entered into between the Company and Mr. Ohri prior to the Company learning of Mr. Ohri’s breaches. In addition to the declaratory judgment, the Company seeks damages arising from Mr. Ohri’s violations, and attorneys’ fees and any forum and arbitration fees. On September 3, 2024, Mr. Ohri filed both a general denial of the Company’s claims against him and counterclaims for breach of his employment agreement and separation agreement. The final hearing date, originally scheduled for June 10, 2025, was postponed to October 6-8, 2026, in order to allow the parties to mediate the dispute. Mediation was held on March 31, 2026. The arbitration was resolved amicably without further litigation. TWF Global Matter On May 24, 2023, TWF Global, LLC (“TWF”) filed a Complaint in the California Superior Court for the County of Los Angeles naming the Company as defendant. The complaint alleges that TWF is the holder of two Convertible Promissory Notes (“Notes”) and that the Company did not deliver shares of Common Stock due on conversion in February 2021. TWF was seeking per diem liquidated damages based on the terms of alleged Notes. On July 14, 2023, the Company filed a motion to dismiss for improper forum because the terms of the Notes, as alleged, require disputes to be filed in New York state and federal courts. TWF voluntarily dismissed its complaint before the California Superior Court of Los Angeles without prejudice. The Company subsequently filed a summons and complaint for interpleader against TWF and Z-One, LLC before the Supreme Court of the State of New York County of New York, asking the Supreme Court to determine if the Company’s shares of Common Stock should be registered to TWF or Z-One LLC, as both of these entities have made conflicting demands for the shares. On February 5, 2024, the Company filed a motion for entry of default against TWF, seeking an order directing the Company to register the shares of Common Stock in the name of Z-One, LLC and that the Company be released from all associated liability and claims. The Court denied the motion without prejudice and agreed to reconsider the motion without further briefing upon the filing of a supplemental party affidavit. On May 9, 2024, Z-One, LLC filed a motion for summary judgement seeking dismissal of the action, representing that Z-One, LLC and TWF have settled their dispute over the entitlement to the Company’s shares of Common Stock and there is no remaining dispute before the Court. On May 21, 2024, the Company filed a supplemental affidavit in support of its motion for entry of default. On November 14, 2024, the Court held a hearing on the parties’ motions, at which the Court found that the motion for entry of default was mooted by the settlement agreement between Z-One, LLC and TWF. The Court ordered that the case be dismissed. On February 17, 2025, Z-One, LLC filed a Summons with Notice in the Supreme Court of the State of New York, County of New York. The Company then filed a demand that Z-One, LLC serve a complaint, and on June 25, 2025, Z-One, LLC filed a Complaint alleging that it is the holder, either originally or by assignment, of a Convertible Note in the principal amount of $150,000, that the Company breached the Convertible Note by failing to deliver conversion shares to Z-One, LLC, and that the Company owes it damages in excess of $500,000. On August 26, 2025, the Company filed a motion to dismiss the Complaint in its entirety for lack of standing and failure to state a cause of action. On February 27, 2026, the court issued a Decision and Order granting the Company’s motion and dismissing the claims asserted in the Complaint in their entirety and with prejudice. On March 26, 2026, Z-One, LLC filed a notice of appeal of the February 27, 2026 dismissal. Z-One, LLC has until September 25, 2026 to perfect its appeal. Silberfein, DiPietro, and Werthman Trust Matters On July 8, 2025, Coby Silberfein filed a summons with notice in the State of New York Supreme Court for the County of New York naming the Company as defendant seeking damages for breach of a securities purchase agreement and convertible note in the principal amount of $100,000. On July 8, 2025, Justin DiPietro filed a summons with notice in the State of New York Supreme Court for the County of New York naming the Company as defendant seeking damages for breach of a securities purchase agreement and convertible note in the principal amount of $100,000. On July 9, 2025, Phillip Werthman Trust filed a summons with notice in the State of New York Supreme Court for the County of New York naming the Company as defendant seeking damages for breach of a securities purchase agreement and convertible note in the principal amount of $100,000. The three summons with notice are identical and allege that the plaintiffs are holders of convertible notes and that the Company breached the convertible notes by failing to deliver shares of Common Stock due on conversion in in 2021. Plaintiffs are seeking specific performance and damages. On August 12, 2025, the Company filed demands that the plaintiffs serve complaints. On September 2, 2025, each plaintiff served a Complaint similar in substance to the summons, except that Plaintiff Silberfein now alleges breach of a convertible note with a principal amount of $150,000, rather than $100,000. Each plaintiff alleges that the Company breached a convertible note by failing to deliver conversion shares to the plaintiff holder, and that the Company owes damages in excess of $500,000. The Company has reached a settlement in principle with the Plaintiffs and is finalizing the terms of the settlement agreements. However, if the lawsuit proceeds, the Company intends to seek dismissal of the complaints. Significant Agreements University of Minnesota 2023 Sponsored Research Agreement On May 20, 2024, the Company entered into a sponsored research agreement (the “2023 Sponsored Research Agreement”) with the Regents of the University of Minnesota (the “University of Minnesota”), effective July 1, 2023.

The purpose of the agreement was for the University of Minnesota to continue work with the Company with three major goals in mind: (1) support the Company’s TriKE® product development and commercial GMP manufacturing efforts; (2) TriKE® pharmacokinetics optimization in humans and investigation of effects of altering the route of administration; and (3) research and development of TriKE® platform. The major deliverables proposed were: (1) creation of Investigational New Drug (“IND”) enabling data for TriKE® constructs in support of the Company’s product development and commercial GMP manufacturing efforts outside of the University of Minnesota; (2) TriKE® platform drug delivery changes to allow transition from intravenous (IV) continuous infusion to alternative drug delivery administration (IV bolus, intraperitoneal [IP], subcutaneous [SQ]) and extended PK in humans and gain an increased understanding of changes in the patient’s native NK cell population as a result of alteration of TriKE® administration; and (3) research and development of TriKE® platform combination with other FDA approved (or soon to be approved) therapeutics and alterations to TriKE® platform through formation of immune complexes. Most studies used TriKE® DNA/amino acid sequences created by the Company under existing licensing terms.

Contingency – NASDAQ Matters On November 20, 2025, the Company received a letter (the “2025 Letter”) from the Nasdaq Listing Qualifications Staff (the “Staff”) notifying the Company that its Common Stock had closed below $1.00 per share for 30 consecutive business days and, as a result, the Company was not in compliance with the $1.00 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”). In accordance with Nasdaq Listing Rule 5810(c)(3)(A), the Company was provided a compliance period of 180 calendar days from the date of the Letter, or until May 19, 2026 (the “Compliance Period”), to regain compliance with the Minimum Bid Price requirement. On May 12, 2026, the Company submitted a request to Nasdaq for an additional 180-day period (the “Second Compliance Period”) to provide additional time for the Company to demonstrate compliance with the Minimum Bid Price Requirement, including by effecting a reverse stock split of its Common Stock, if necessary. On May 20, 2026, the Company, received a letter from the Staff notifying the Company that the Staff had granted the Company the Second Compliance Period of 180 calendar days, or until November 16, 2026, to regain compliance with the Minimum Bid Price Requirement. If at any time during the Second Compliance Period the closing bid price of the Common Stock, is at least $1.00 per share for a minimum of 10 consecutive business days (unless the Staff exercises its discretion to extend this ten business day period pursuant to Nasdaq Listing Rule 5810(c)(3)(H)), Nasdaq will provide the Company written confirmation of compliance with the Minimum Bid Price Requirement, and the matter will be closed. The Company intends to monitor the closing bid price of the Common Stock and assess its available options to regain compliance with the Minimum Bid Price Requirement and continue listing on The Nasdaq Capital Market. There can be no assurance that the Company will be able to regain compliance with the Minimum Bid Price requirement or will otherwise be in compliance with other applicable Nasdaq listing rules. If the Common Stock is delisted from Nasdaq, our ability to raise capital through public offerings of our securities and to finance our operations could be adversely affected. We also believe that delisting would likely result in decreased liquidity and/or increased volatility in the Common Stock and could harm our business and future prospects. In addition, we believe that, if the Common Stock is delisted, our stockholders would likely find it more difficult to obtain accurate quotations as to the price of the Common Stock and it may be more difficult for stockholders to buy or sell shares of Common Stock at competitive market prices, or at all.
