Note 1 - Description of Business and Basis of Presentation

Unless the context requires otherwise, references to “Genprex,” the “Company,” “we,” “us” or “our” in this Quarterly Report on Form 10-Q refer to Genprex, Inc. Genprex, incorporated in Delaware in April 2008, is a clinical stage gene therapy company pioneering the development of gene-based therapies for large patient populations with unmet medical needs. The Company’s oncology platform utilizes its systemic, non-viral ONCOPREX® Delivery System which uses lipid-based nanoparticles in a lipoplex form to deliver tumor suppressor gene-expressing plasmids to cancer cells. The product is administered intravenously, where it is taken up by tumor cells that then express tumor suppressor proteins that were deficient in the tumor. The Company’s diabetes technology is designed to work in Type 1 diabetes by transforming alpha cells in the pancreas into functional beta-like cells, which can produce insulin but may be distinct enough from beta cells to evade the body’s immune system. In Type 2 diabetes, the Company’s technology is believed to work by replenishing and rejuvenating exhausted beta cells that make insulin.

Oncology Platform

Genprex’s lead oncology drug candidate, REQORSA® Gene Therapy (generic name: quaratusugene ozeplasmid), previously referred to as GPX-001, is initially being developed in combination with prominent, approved cancer drugs to treat Non-Small Cell Lung Cancer (“NSCLC”) and Small Cell Lung Cancer (“SCLC”). REQORSA has multimodal effects on cancer cells. It has a mechanism of action whereby it decreases cancer cell growth by decreasing glucose metabolism, interrupts cell signaling pathways that cause replication and proliferation of cancer cells, re-establishes pathways for apoptosis, or programmed cell death, in cancer cells, and increases the immune response against cancer cells. In preclinical studies, REQORSA has been shown to be complementary with targeted drugs and immunotherapies. The Company’s strategy is to develop REQORSA in combination with currently approved therapies and the Company believes REQORSA’s unique attributes position it to provide treatments that improve on these current therapies for patients with NSCLC, SCLC, and possibly other cancers.

The TUSC2 gene, which is the key component of REQORSA and plays a vital role in cancer suppression and normal cell metabolism, is one of a series of genes on the short arm of Chromosome 3 whose therapeutic use is covered by the Company’s exclusive worldwide licenses from The University of Texas MD Anderson Cancer Center (“MD Anderson”). The Company believes that its ONCOPREX Delivery System allows for the delivery of a number of cancer-fighting tumor suppressor genes, alone or in combination with other cancer therapies, to combat multiple types of cancer and the Company is in early stages of discovery programs to identify other cancer candidates. Since not all patients respond to REQORSA, the Company has been collaborating with researchers at MD Anderson to identify biomarkers that might predict a strong positive response or a lack of response to REQORSA in patients with lung cancer. This preclinical effort has led to the identification of two proteins whose expression appears to predict response to REQORSA. This work, titled “TROP2 and PTEN are biomarkers of primary resistance to TUSC2 gene therapy in non-small cell lung cancer” was accepted for a poster presentation at the meeting of the American Association of Cancer Research in April 2026. These findings suggest that TROP2 and PTEN may serve as biomarkers to predict TUSC2 response and guide therapeutic strategies in NSCLC. TROP2 (trophoblast cell-surface antigen 2) is a transmembrane glycoprotein that functions as a cell surface receptor. TROP2 overexpression in adult tissues is a hallmark of many solid tumors, making it a major target for modern cancer therapies. PTEN (phosphatase and tensin homolog) is a tumor suppressor gene that serves as a multi-functional cancer biomarker in a number of cancers, with potential for risk assessment, diagnosis and treatment planning. Validation in specimens from clinical trials will be needed to determine whether these potential biomarkers predict clinical response. In April 2026, the Company entered into a new sponsored research agreement with MD Anderson to study biomarkers that may predict patient response to REQORSA. The Company is testing patient samples from its clinical trials for selected biomarkers to determine if sensitivities exist among the Company’s existing patient population in an effort to guide patient selection and optimize clinical outcomes.

Acclaim – 1: The Acclaim-1 study is a Phase 1/2 clinical trial that has three portions - a Phase 1 dose escalation portion, a Phase 2a expansion portion, and a Phase 2b randomized portion. The Company currently is enrolling and treating patients in the Phase 2a expansion portion of its Phase 1/2 Acclaim-1 clinical trial. The Acclaim-1 trial uses a combination of REQORSA and AstraZeneca’s Tagrisso® (osimertinib) in patients with late-stage NSCLC who have activating epidermal growth factor receptor (“EGFR”) mutations and disease progression on treatment with Tagrisso or Tagrisso-containing regimens. Following the May 2023 completion of the Phase 1 dose escalation portion of the study, the Acclaim-1 Safety Review Committee (“Acclaim-1 SRC”) approved advancement from the Phase 1 dose escalation portion to the Phase 2a expansion portion of the study. Based on a review of safety data which showed no dose limiting toxicities (“DLTs”), the Acclaim-1 SRC determined the recommended Phase 2 dose (“RP2D”) of REQORSA to be 0.12 mg/kg administered every 21 days. This was the highest dose level delivered in the Phase 1 portion of the study and is twice the highest dose level delivered in the Company’s prior clinical trial combining REQORSA with Tarceva® (erlotinib) for the treatment of late-stage lung cancer. There were three patients out of the twelve originally enrolled in the Phase 1 dose escalation portion of the study who had prolonged progression-free survival (“PFS”). One patient attained a partial remission after the second course of REQORSA and Tagrisso and has maintained this response through 64 courses of treatment (approximately 48 months) and this patient continues to receive REQORSA and Tagrisso treatment to date. A second patient had stable disease without disease progression through 32 courses of treatment (approximately 24 months), but then had disease progression and REQORSA treatment was stopped. A third patient had stable disease without disease progression through 14 courses of treatment (approximately 10 months) before disease progression and is no longer receiving treatment. The results of the Phase 1 dose escalation portion of the study were published in Clinical Lung Cancer, a peer-reviewed journal covering various aspects of clinical and translational research of lung cancer, in January 2026. Genprex opened the Phase 2a expansion portion of the study and enrolled and dosed the first patient in January 2024. The Phase 2a expansion portion of the trial is expected to enroll approximately 33 patients, all of whom had disease progression on Tagrisso or Tagrisso-containing regimens. There will be an interim analysis following the treatment of 19 patients in the Phase 2a portion of the Acclaim-1 study. The Company expects to complete the enrollment of the first 19 patients for interim analysis in the Phase 2a expansion portion of the study in the first half of 2026 and expects the interim analysis in the second half of 2026.

The Food and Drug Administration (“FDA”) has granted Fast Track Designation for the Acclaim-1 treatment combination of REQORSA and Tagrisso in NSCLC patients who have progressed on Tagrisso treatment.

The Phase 2a expansion portion of the Acclaim-1 study provides the Company the advantage of early insight into drug effectiveness in defined and distinct patient populations at the maximum tolerated dose or RP2D in order to better evaluate efficacy and increase the likelihood of a successful randomized Phase 2 trial which will follow the expansion portion of the study.

Acclaim – 3: The Acclaim-3 study has two portions - a Phase 1 dose escalation portion and a Phase 2 expansion portion. The Company is currently enrolling and treating patients in the Phase 2 expansion portion of its Phase 1/2 Acclaim-3 clinical trial. The Acclaim-3 clinical trial uses a combination of REQORSA and Genentech, Inc.’s Tecentriq® (atezolizumab) as maintenance therapy for patients with extensive stage small cell lung cancer (“ES-SCLC”) who did not develop tumor progression after receiving Tecentriq and chemotherapy as initial standard treatment. Patients are treated with REQORSA and Tecentriq until disease progression or unacceptable toxicity is experienced. In December 2024, the Company announced that it had completed the Phase 1 dose escalation portion of the Acclaim-3 clinical trial. Based on full safety data, which showed no DLTs, the Acclaim-3 Safety Review Committee (“Acclaim-3 SRC”) determined that the RP2D of REQORSA will be 0.12 mg/kg administered every 21 days, which was the highest dose level delivered in the Phase 1 portion of the trial, and approved the opening of the Phase 2 expansion portion of the trial. Although decreases in tumor size are not expected during maintenance therapy with atezolizumab alone, there were two patients out of the six enrolled in the Phase 1 dose escalation portion of the study who had marked decreases in measurable disease. The Company previously reported that the first patient treated in the Phase 1 dose escalation portion of the Acclaim-3 trial had a partial remission, which is defined as at least a thirty percent (30%) decrease in tumor size, from prior to the start of maintenance therapy to the time of the CT scan performed after two cycles of maintenance therapy. A CT scan performed after four cycles of maintenance therapy (three months), confirmed that the patient still had a 30% decrease in tumor size in measurable lesions; however, one lesion not previously measurable had grown in size, thus leading to a conclusion of disease progression at that time. Another patient in the Phase 1 dose escalation portion of the Acclaim-3 trial had a twenty-three percent (23%) decrease in tumor size from prior to the start of maintenance therapy to the time of the CT scan performed after two cycles of maintenance therapy. This patient received seven cycles of study therapy before progressing after 4.2 months. In addition, one patient in the Phase 1 dose escalation portion of the study achieved an unconfirmed partial remission after 24 cycles of therapy and continues to receive study treatment in the trial after more than 19 months. The Company anticipates that the Phase 2 expansion portion will enroll approximately 50 patients at approximately 10 to 15 U.S sites. Patients will be treated with REQORSA and Tecentriq until disease progression or unacceptable toxicity is experienced. The primary endpoint of the Phase 2 portion is to determine the 18-week progression-free survival rate from the start of maintenance therapy with REQORSA and Tecentriq in patients with ES-SCLC. Patients will also be followed for survival. A Phase 2 futility analysis will be performed after the 25th patient enrolled and treated reaches 18 weeks of follow up. The Company expects to complete enrollment of the first 25 patients for interim analysis in the Phase 2 expansion portion of the study in the first half of 2026 and expects the interim analysis in the second half of 2026.

The Acclaim-3 clinical trial has received FDA Fast Track Designation for this patient population and Acclaim-3 has also received an FDA Orphan Drug Designation.

Diabetes Gene Therapy

In diabetes, Genprex has exclusively licensed from the University of Pittsburgh of the Commonwealth System of Higher Education (“University of Pittsburgh” or “UP”) multiple technologies relating to the development of a gene therapy product for each of Type 1 and Type 2 diabetes. The same novel approach is used in each of Type 1 and Type 2 diabetes whereby an adeno-associated virus (“AAV”) vector containing the Pdx1 and MafA genes is administered directly into the pancreatic duct. In humans, this can be done with a routine endoscopy procedure. The Company’s diabetes product candidates are currently being evaluated and optimized in preclinical studies at the University of Pittsburgh. GPX-002 is being developed for the treatment of both Type 1 diabetes and Type 2 diabetes. GPX-002 for Type 1 diabetes is designed to work by transforming alpha cells in the pancreas into functional beta-like cells, which can produce insulin but may be distinct enough from beta cells to evade the body’s immune system. In a similar approach, GPX-002 for Type 2 diabetes, where autoimmunity is not at play, is believed to work by replenishing and rejuvenating exhausted beta cells that make insulin. The Company is currently working with the University of Pittsburgh on species analyses for the animal models as well as other regulatory and clinical strategic planning, including the initiation of research in Type 2 diabetes animal models. In December 2025, the Company also executed on its strategic goal to submit a meeting request to the FDA by the end of the year to discuss the necessary Investigational New Drug (“IND”)-enabling preclinical studies, an important step before potentially initiating clinical trials in humans. See the discussion captioned “Recent Developments – Diabetes Gene Therapy Updates” in “Part I, Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations” appearing in this Quarterly Report on Form 10-Q below for more information on the Company’s meeting with the FDA which occurred in February 2026. In May 2025, following the completion of the Company’s August 2022 sponsored research agreement with UP, the Company entered into a new sponsored research agreement with UP to study Type 1 diabetes and Type 2 diabetes in animal models. The new sponsored research agreement also includes a revised research plan to encompass the Company’s most recent technologies to which Genprex originally acquired exclusive rights from UP in July 2023 as amended and restated in the comprehensive New UP License Agreement in February 2025 (as defined and described below). These include a MafB promoter to drive expression of the Pdx1 and MafA transcription factors that can potentially be used for both Type 1 and Type 2 diabetes. See also “Note 6 – Commitments and Contingencies”.

On February 17, 2025, the Company and the University of Pittsburgh entered into an amended and restated Exclusive License Agreement (the “New UP License Agreement”), which updated and consolidated into a single agreement the Company’s prior license agreements with UP. Pursuant to the New UP License Agreement, UP granted to the Company a worldwide, exclusive license for certain patents and related technology, collectively referred to as the “Licensed Technology,” and a worldwide, non-exclusive license to use certain related know-how. The Licensed Technology covered by the New UP License Agreement is based on the same general gene therapy approach as covered under the Company’s prior license agreements with UP (less the previously-licensed macrophage technology), whereby an adeno-associated virus vector containing the Pdx1 and MafA genes is administered directly into the pancreatic duct. More specifically, the Licensed Technology covered by the New UP License Agreement is related to a gene therapy for both Type 1 diabetes and Type 2 diabetes using the genes of the Pdx1 and MafA transcription factors controlled by insulin, glucagon and MafB promoters.

In February 2023, the Company’s research collaborators at UP presented preclinical data in a non-human primate (“NHP”) model of Type 1 diabetes highlighting the therapeutic potential of GPX-002 at the 16th International Conference on Advanced Technologies & Treatments for Diabetes (“ATTD 2023”) in Berlin, Germany. The statistically significant study results showed the treated animals had decreased insulin requirements, increased c-peptide levels, and improved glucose tolerance compared to baseline. In April 2023, the Company hosted a Key Opinion Leader virtual event entitled “Novel Gene Therapy to Treat Type 1 Diabetes,” which discussed preclinical data reported at ATTD 2023 supporting gene therapy to treat Type 1 diabetes. In June 2025, the Company’s collaboration partners had two presentations at the 2025 American Diabetes Association (“ADA”) 85th Scientific Sessions. The Company’s research collaborators from UP were invited to give an oral presentation highlighting their work in NHP models of Type 1 diabetes. In addition, the Company’s contract development and manufacturing organization collaborators presented a poster on a non-viral lipid nanoparticle delivery system that would allow a patient to receive multiple treatments.

Formation of Wholly Owned Subsidiary

On February 18, 2025, Genprex announced the formation of a wholly-owned subsidiary, Convergen Biotech, Inc. (“Convergen”) in connection with a potential separation of the diabetes clinical development program. If, and when, a potential separation is completed, the Company would plan to transfer the diabetes program into Convergen in an effort to focus development and commercialization efforts separately from the Company’s oncology program and other oncology pipeline assets.

Capital Requirements, Liquidity and Going Concern Considerations

The Company’s unaudited condensed consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of America (“US GAAP”) applicable to a going concern, which contemplates the realization of assets and liquidation of liabilities in the normal course of business. However, the Company has sustained substantial losses from operations since inception and has no current source of revenue. In addition, the Company has used, rather than provided, cash in its operations. Genprex expects to continue to incur significant expenditures to further clinical trials for the commercial development of its patents.

The Company recognizes that it must obtain additional capital resources to successfully commercialize its product candidates. To date, Genprex has received funding in the form of equity and debt, and the Company plans to seek additional funding in the future. However, no assurances can be given that it will be successful in raising additional capital. If the Company is not able to timely and successfully raise additional capital, the timing of its clinical trials, financial condition and results of operations may be materially and adversely affected. These unaudited condensed consolidated financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts and classification of liabilities.

Genprex believes that its current cash and cash equivalents will be sufficient to fund expenditure requirements for its necessary operations and expected clinical trial activities into the second half of 2027. Genprex has based these estimates, however, on assumptions that may prove to be wrong, and could spend available financial resources much faster than it currently expects. The Company will need to raise additional funds to continue funding its development and operations. The Company plans to secure such additional funding and is evaluating various strategies to obtain additional financing, although the Company can give no assurance that its plans or strategies will be effectively implemented in such a way that they will sufficiently alleviate or mitigate the conditions and events noted above.

As a result of its recurring losses from operations and the need for additional financing to fund its operating and capital requirements, there is uncertainty regarding the Company’s ability to maintain liquidity sufficient to operate its business effectively, which raises substantial doubt as to the Company’s ability to continue as a going concern. These unaudited condensed consolidated financial statements do not include any adjustments that might be necessary if Genprex is unable to continue as a going concern.

Note 2 - Summary of Significant Accounting Policies

Genprex’s unaudited condensed consolidated financial statements have been prepared in accordance with US GAAP and the requirements of the United States Securities and Exchange Commission (the “SEC”) for interim reporting. As permitted under those rules, certain footnotes or other financial information that is normally required by US GAAP can be condensed or omitted. Accordingly, they do not include all of the information and footnotes normally included in financial statements prepared in conformity with US GAAP. The December 31, 2025 balance sheet was derived from the December 31, 2025 audited financial statements. Genprex’s unaudited condensed consolidated financial statements should be read in conjunction with the financial statements and notes thereto included in the Company’s 2025 Annual Report on Form 10-K, filed with the SEC on March 30, 2026 (the “Form 10-K”).

The accompanying condensed consolidated financial statements are unaudited and include all adjustments (consisting of normal recurring adjustments) that management considers necessary for a fair presentation of Genprex’s condensed consolidated financial position and results of operations for the interim periods presented. The results of operations for the interim periods are not necessarily indicative of the results that may be expected for any other interim period or for the entire year.

A summary of Genprex’s significant accounting policies consistently applied in the preparation of the accompanying unaudited condensed consolidated financial statements follows.

Principles of Consolidation

The accompanying unaudited condensed consolidated financial statements, which include the accounts of the Company and its wholly-owned subsidiary, Convergen Biotech, Inc., have been prepared in accordance with US GAAP for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. All significant intercompany balances and transactions are eliminated in consolidation. As of March 31, 2026, Convergen Biotech, Inc. has yet to initiate operating activity.

Reverse Stock Split

On October 21, 2025, Genprex completed a 1-for-50 reverse stock split (“2025 Reverse Split”) of its issued and outstanding shares of common stock. The 2025 Reverse Split did not change the number of authorized shares of common stock or par value of the common stock. All references in these unaudited condensed consolidated financial statements to shares, share prices, exercise prices, and other per share information in all periods have been adjusted, on a retroactive basis, to reflect the 2025 Reverse Split (see “Note 4 – Equity – 2025 Reverse Stock Split”).

Use of Estimates

The preparation of Genprex’s unaudited condensed consolidated financial statements in conformity with US GAAP requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the unaudited condensed consolidated financial statements and the reported amounts of expenses during the reporting period. Actual results could differ from those estimates.

Cash and Cash Equivalents

Genprex considers all highly liquid short-term investments with an initial maturity of three months or less to be cash equivalents. Any amounts of cash in financial institutions which exceed Federal Deposit Insurance Corporation (“FDIC”) insured limits expose the Company to cash concentration risk. The Company has cash in a money market account and had $17,799,219 and $7,580,820 in excess of FDIC insured limits of $250,000 at March 31, 2026 and December 31, 2025, respectively. Any loss incurred or a lack of access to such funds could have a significant adverse impact on the Company’s financial condition, results of operations, and cash flows.

Net Loss Per Share

Basic net loss per share is calculated by dividing the net loss by the weighted-average number of shares of common stock outstanding for the period, without consideration for potential dilutive shares of common stock, which includes common stock equivalents consisting of (i) 1,325,388 unexercised options granted by the Company’s board of directors and unexercised warrants to purchase shares of common stock, and (ii) 85,179 unvested restricted stock units granted by the Company’s board of directors representing the right upon vesting to receive shares of common stock, in each case as of March 31, 2026.

MARCH 31, 2026

Fair Value of Financial Instruments

The carrying amounts reported in the condensed consolidated balance sheets for cash, money-market savings account, accounts receivable, and accounts payable approximate fair value because of the immediate or short-term maturity of these financial instruments.

Accounting Standards Codification ("ASC") 820, Fair Value Measurements and Disclosures, defines fair value, provides a consistent framework for measuring fair value under US GAAP and expands fair value financial statement disclosure requirements. ASC 820’s valuation techniques are based on observable and unobservable inputs. Observable inputs reflect readily obtainable data from independent sources, while unobservable inputs reflect our market assumptions. ASC 820 classifies these inputs into the following hierarchy:

Level 1: Quoted prices for identical instruments in active markets.

Level 2: Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value drivers are observable.

Level 3: Instruments with primarily unobservable value drivers.

Property and Equipment

Property and equipment are stated at cost less accumulated depreciation. Depreciation is calculated using the straight-line method over the estimated useful lives of the assets, which range from three to five years. Routine maintenance and repairs are charged to expense as incurred and major renovations or improvements are capitalized.

Research and Development Costs

Research and development expenditures consist of costs incurred to conduct research, develop engineering materials for further study, and develop clinical strategies for current and future programs associated with the Company’s preclinical and Phase 1/2 clinical trials. These expenditures are expensed in the period incurred and include payments to collaborative research partners, manufacturing partners and consultants, and clinical strategy partners, wages and associated employee benefits, facilities, and overhead costs.

Materials acquired to be used in clinical research, that have an alternative future use, are capitalized when the materials are acquired, and included in research and development supplies. These supplies are recognized as expense as they are consumed through use for testing or clinical activities, or have spoiled. The costs of materials that were acquired for a particular research and development activity and have no alternative future use are expensed in the period acquired.

Research and development supplies purchased, valued at cost, and capitalized for future use were $1,503,207 and $1,802,228 at March 31, 2026 and December 31, 2025, respectively.

Intellectual Property

Intellectual property consists of legal and related costs associated with patents, trademarks, and other proprietary technology and rights developed, acquired, or licensed by Genprex. Costs related to filing and pursuing patent applications are expensed as incurred, as recoverability of such expenditures is uncertain. These patent-related legal costs are reported as a component of general and administrative expenses.

Accounting for Stock-Based Compensation

Genprex uses the fair value-based method of accounting for stock-based compensation for options granted to employees, independent consultants and contractors. The Company measures options granted at fair value determined as of the grant date and recognizes the expense over the periods in which the options vest or are expected to vest and related services are rendered based on the terms and conditions of the award. Generally, where the award only has a service condition, the requisite service period is the same as the vesting period.

Long-Lived Assets

Genprex reviews long-lived assets and certain identifiable intangibles held and used for possible impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. In evaluating the fair value and future benefits of its intangible assets, the Company performs an analysis of the anticipated undiscounted future net cash flow of the individual assets over the remaining amortization period. The Company recognizes an impairment loss if the carrying value of the asset exceeds the discounted expected future cash flows. During the three months ended March 31, 2026, there were no deemed impairments of the Company’s long-lived assets.

Derivative Liability

The Company evaluates all features contained in financing agreements to determine if there are any embedded derivatives that require separate accounting from the underlying agreement under ASC 815, Derivatives and Hedging. An embedded derivative that requires separation is accounted for as a separate asset or liability from the host agreement. The derivative asset or liability is accounted for at fair value, with changes in fair value recognized in the condensed consolidated statements of operations within the other financing costs line item. The Company determined that certain features under the Equity Line of Credit (see "Note 4 – Equity – Equity Line of Credit") qualified as an embedded derivative. The derivative liability is accounted for separately from the Equity Line of Credit Purchase Agreement and is accounted for at fair value. $22,500 has been recorded on the accompanying condensed consolidated balance sheets as of March 31, 2026 and December 31, 2025, related to this derivative liability.

Recent Accounting Developments

Accounting pronouncements issued but not effective until after March 31, 2026, are not expected to have a significant effect on the Company’s consolidated financial condition, results of operations, or cash flows.

In December 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which modifies the rules on income tax disclosures to require disaggregated information about a reporting entity’s effective tax rate reconciliation as well as information on income taxes paid. The standard is intended to benefit investors by providing more detailed income tax disclosures that would be useful in making capital allocation decisions. The guidance is effective for annual periods beginning after December 15, 2024, with early adoption permitted. The Company adopted the standard effective January 1, 2025 and there was no material impact to the Company’s consolidated financial statements.

In December 2025, the FASB issued ASU 2025-11, Interim Reporting (Topic 270): Narrow-Scope Improvements, which is intended to clarify the applicability of interim reporting guidance, the types of interim reporting and the form and content of interim US GAAP financial statements. ASU 2025-11 will be effective for the Company’s fiscal year beginning on September 1, 2028 and the Company is currently evaluating the impact it may have on its interim condensed consolidated financial statements.

At-The-Market Offering

On December 13, 2023, Genprex entered into an At The Market (“ATM”) Offering Agreement (the “Sales Agreement”) with H.C.

Any Shares offered and sold pursuant to the Sales Agreement will be issued pursuant to the Company’s currently effective shelf Registration Statement on Form S-3 (File No. 333-271386) filed with the SEC on April 21, 2023, which was declared effective on June 9, 2023, as may be amended or supplemented from time to time, or pursuant to any new or successor shelf Registration Statement of the Company. The Company has agreed to pay the Agent a commission equal to three percent (3%) of the gross sales proceeds of any Shares sold through the Agent under the Sales Agreement, and also has provided the Agent with customary indemnification and contribution rights.

Equity Line of Credit

On June 11, 2025, Genprex entered into an equity line of credit (“ELOC”) purchase agreement (the “Purchase Agreement”) with Lincoln Park Capital Fund, LLC (“Lincoln Park”), pursuant to which Lincoln Park committed to purchase up to $12.5 million in shares of the Company’s common stock (subject to certain conditions and limitations contained in the Purchase Agreement) from time to time at the Company’s sole discretion over the 24-month term of the Purchase Agreement (the “2025 ELOC Facility”). Sales of shares of common stock to Lincoln Park under the Purchase Agreement will depend on a variety of factors to be determined by the Company from time to time, including, among others, market conditions, the trading price of the common stock and the Company’s determination as to the appropriate sources of funding for its operations. Due to certain pricing and settlement provisions, the Purchase Agreement qualifies as a standby purchase equity agreement and includes an embedded put option and an embedded forward contract. Genprex will account for the Purchase Agreement as a derivative measured at fair value, with changes in fair value recognized in the condensed consolidated statement of operations. The put option derivative liability is accounted for on a fair value basis under the provisions of ASC 815, Derivatives and Hedging. The derivative associated with the Purchase Agreement was deemed de minimus at inception until the Company obtained stockholder approval to issue shares of common stock to Lincoln Park under the Purchase Agreement in excess of the Exchange Cap (as defined in the Purchase Agreement). The fair value of the ELOC Purchase Agreement contemplated future purchase decisions based on economic considerations and relevant stock issuance rules and limitations and has been determined using a Monte Carlo simulation. The fair value of the ELOC derivative liability was $22,500 at March 31, 2026 and December 31, 2025

The following table provides the carrying value and fair value of the ELOC derivative liability of the Company measured at fair value on a recurring basis as of March 31, 2026:

2018 Equity Incentive Plan

The Company’s board of directors and stockholders have approved and adopted the Genprex 2018 Equity Incentive Plan (“2018 Plan”), which initially became effective on the completion of the Company’s IPO on April 3, 2018. The 2018 Plan provides for the grant of incentive stock options that are intended to qualify under Section 422 of the Internal Revenue Code of 1986, as amended (“ISOs”), nonstatutory stock options, stock appreciation rights, restricted stock awards, RSU awards, performance-based stock awards and performance-based cash awards. ISOs may be granted only to employees. All other awards may be granted to employees, including officers, and to the Company’s non-employee directors and consultants.

A total of 2,080 shares of common stock were initially available under the 2018 Plan, plus a number of shares of common stock (not to exceed 1,314 shares) subject to outstanding awards under the Company’s 2009 Equity Incentive Plan (the “2009 Plan”) as of the IPO that expire, are forfeited or otherwise terminate or that are used to cover the exercise price or applicable tax withholdings. No further grants will be made under the 2009 Plan. In addition, the number of shares of common stock reserved for issuance under the 2018 Plan automatically increases on January 1 of each year, since January 1, 2019, by 5% of the total number of shares of the Company’s common stock outstanding on December 31 of the preceding calendar year, or a lesser number of shares determined by the Company’s board of directors or a committee of the board of directors appointed to administer the 2018 Plan.

On August 15, 2025 at the 2025 Annual Meeting of Stockholders, the Company’s stockholders approved the Company’s amended and restated 2018 Plan (the “2018 Amended Plan”). The principal changes to the 2018 Plan implemented by the 2018 Amended Plan include amendments to (i) increase the number of shares of the Company’s common stock authorized for issuance under the 2018 Plan by an additional 130,000 shares (subject to adjustment for stock splits, stock dividends and similar events), (ii) extend the term of the 2018 Plan to June 30, 2035 (the 10-year anniversary of the Board’s adoption of the Amended Equity Plan) and (iii) remove provisions of the 2018 Plan that had been included to comply with the exception for the deductibility of “performance-based compensation” under Section 162(m) of the Internal Revenue Code of 1986, as amended, which was repealed by the Tax Cuts and Jobs Act of 2017. The 2018 Amended Plan became effective upon its approval by the Company’s stockholders at the 2025 Annual Meeting.

On January 1, 2025 and 2026, the number of shares of common stock reserved for issuance under the 2018 Plan was increased by an aggregate of 10,861 and 164,574 shares, respectively.

The Company’s board of directors and stockholders approved and adopted the Genprex 2018 Employee Stock Purchase Plan (“ESPP”), which became effective on April 3, 2018. The ESPP has not yet been utilized as a benefit available to the Company’s employees. The ESPP authorizes the issuance of 105 shares of common stock pursuant to purchase rights that may be granted to eligible employees. The number of shares of common stock reserved for issuance under the ESPP is automatically increased on January 1 of each calendar year, beginning on January 1, 2019, by 2% of the total number of shares of common stock outstanding on December 31 of the preceding calendar year, or a lesser number of shares determined by the administrator of the ESPP.

Commitments

MD Anderson Cancer Center

In July 2018, Genprex entered into a two-year sponsored research agreement with MD Anderson to sponsor preclinical studies focused on the combination of REQORSA with an immunotherapy with a projected total cost of approximately $2 million. This agreement was extended beyond the original expiration date, expiring in May 2022 after giving effect to such extension. In August 2022, the Company entered into a three-year sponsored research agreement with MD Anderson (the “August 2022 SRA”) to sponsor preclinical studies focused on REQORSA and NPRL2 in oncology to resensitize NSCLC and SCLC to targeted therapies and immunotherapies with an initial projected total cost of approximately $2.9 million. On June 7, 2024, the Company amended the August 2022 SRA with MD Anderson to (i) extend the sponsored research program an additional six months, (ii) amend the quarterly budget from approximately $240,000 to $165,000 per quarter, and (iii) amend the total commitment from $2.9 million to approximately $2.76 million. The Company incurred $165,701 of expense from this agreement during the three months ended March 31, 2026. As of March 31, 2026, the Company has paid approximately $2.6 million toward this $2.76 million commitment.

In 2011, the Company agreed to assume certain contractual and other obligations of IRI in consideration for the sublicense rights, expertise, and assistance associated with certain technologies and intellectual property originally licensed to another party under the 1994 License Agreement with MD Anderson (“Original MD Anderson License Agreement”). These technologies and intellectual property were later sublicensed to IRI (the “IRI Sublicense”). The Company also agreed to pay royalties of 1% on sales of certain licensed products for a period of 21 years following the termination of the later of the Original MD Anderson License Agreement and the IRI Sublicense. The Company assumed patent prosecution costs and an annual minimum royalty of $20,000 payable to the National Institutes of Health (“NIH”).

On March 3, 2021, the Company entered into an amendment (the “MD License Amendment”) to the Patent and Technology License Agreement dated May 4, 2020, with MD Anderson. The MD License Amendment grants Genprex a worldwide, exclusive, sublicensable license to an additional portfolio of six patents and one patent application and related technology for methods for treating cancer by administration of a TUSC2 therapy in conjunction with EGFR inhibitors or other anti-cancer therapies in patients predicted to be responsive to TUSC2 therapy.

Overview

We are a clinical stage gene therapy company pioneering the development of gene-based therapies for large patient populations with unmet medical needs. Our oncology platform utilizes our systemic, non-viral ONCOPREX® Delivery System which uses lipid-based nanoparticles in a lipoplex form to deliver tumor suppressor gene-expressing plasmids to cancer cells. The product is administered intravenously, where it is taken up by tumor cells that then express tumor suppressor proteins that were deficient in the tumor. Our diabetes technology is designed to work in Type 1 diabetes by transforming alpha cells in the pancreas into functional beta-like cells, which can produce insulin but may be distinct enough from beta cells to evade the body’s immune system. In Type 2 diabetes, our technology is believed to work by replenishing and rejuvenating exhausted beta cells that make insulin.

Oncology Platform

Our lead oncology drug candidate, REQORSA® Gene Therapy (generic name: quaratusugene ozeplasmid), previously referred to as GPX-001, is initially being developed in combination with prominent, approved cancer drugs to treat Non-Small Cell Lung Cancer (“NSCLC”) and Small Cell Lung Cancer (“SCLC”). REQORSA has multimodal effects on cancer cells. It has a mechanism of action whereby it decreases cancer growth by decreasing glucose metabolism, interrupts cell signaling pathways that cause replication and proliferation of cancer cells, re-establishes pathways for apoptosis, or programmed cell death, in cancer cells, and increases the immune response against cancer cells. In preclinical studies, REQORSA has been shown to be complementary with targeted drugs and immunotherapies. Our strategy is to develop REQORSA in combination with currently approved therapies and we believe REQORSA’s unique attributes position it to provide treatments that improve on these current therapies for patients with NSCLC, SCLC, and possibly other cancers.

The TUSC2 gene, which is the key component of REQORSA and plays a vital role in cancer suppression and normal cell metabolism, is one of a series of genes on the short arm of Chromosome 3 whose therapeutic use is covered by our exclusive worldwide licenses from The University of Texas MD Anderson Cancer Center (“MD Anderson”). We believe that our ONCOPREX Delivery System allows for the delivery of a number of cancer-fighting tumor suppressor genes, alone or in combination with other cancer therapies, to combat multiple types of cancer and we are in early stages of discovery programs to identify other cancer candidates. Since not all patients respond to REQORSA, we have been collaborating with researchers at MD Anderson to identify biomarkers that might predict a strong positive response or a lack of response to REQORSA in patients with lung cancer. This preclinical effort has led to the identification of two proteins whose expression appears to predict response to REQORSA. This work, titled “TROP2 and PTEN are biomarkers of primary resistance to TUSC2 gene therapy in non-small cell lung cancer” was accepted for a poster presentation at the meeting of the American Association of Cancer Research in April 2026. These findings suggest that TROP2 and PTEN may serve as biomarkers to predict TUSC2 response and guide therapeutic strategies in NSCLC. TROP2 (trophoblast cell-surface antigen 2) is a transmembrane glycoprotein that functions as a cell surface receptor. TROP2 overexpression in adult tissues is a hallmark of many solid tumors, making it a major target for modern cancer therapies. PTEN (phosphatase and tensin homolog) is a tumor suppressor gene that serves as a multi-functional cancer biomarker in a number of cancers, with potential for risk assessment, diagnosis and treatment planning. Validation in specimens from clinical trials will be needed to determine whether these potential biomarkers predict clinical response. In April 2026, we entered into a new sponsored research agreement with MD Anderson to study biomarkers that may predict patient response to REQORSA. We are testing patient samples from our clinical trials for selected biomarkers to determine if sensitivities exist among our existing patient population in an effort to guide patient selection and optimize clinical outcomes.

Acclaim – 1: The Acclaim-1 study is a Phase 1/2 clinical trial that has three portions - a Phase 1 dose escalation portion, a Phase 2a expansion portion, and a Phase 2b randomized portion. We currently are enrolling and treating patients in the Phase 2a expansion portion of our Phase 1/2 Acclaim-1 clinical trial. The Acclaim-1 trial uses a combination of REQORSA and AstraZeneca’s Tagrisso® (osimertinib) in patients with late-stage NSCLC who have activating epidermal growth factor receptor (“EGFR”) mutations and disease progression on treatment with Tagrisso or Tagrisso-containing regimens. Following the May 2023 completion of the Phase 1 dose escalation portion of the study, the Acclaim-1 Safety Review Committee (“Acclaim-1 SRC”) approved advancement from the Phase 1 dose escalation portion to the Phase 2a expansion portion of the study. Based on a review of safety data which showed no dose limiting toxicities (“DLTs”), the Acclaim-1 SRC determined the recommended Phase 2 dose (“RP2D”) of REQORSA to be 0.12 mg/kg administered every 21 days. This was the highest dose level delivered in the Phase 1 portion of the study and is twice the highest dose level delivered in our prior clinical trial combining REQORSA with Tarceva® (erlotinib) for the treatment of late-stage lung cancer. There were three patients out of the twelve originally enrolled in the Phase 1 dose escalation portion of the study who had prolonged progression-free survival (“PFS”). One patient attained a partial remission after the second course of REQORSA and Tagrisso and has maintained this response through 64 courses of treatment (approximately 48 months) and this patient continues to receive REQORSA and Tagrisso treatment to date. A second patient had stable disease without disease progression through 32 courses of treatment (approximately 24 months), but then had disease progression and REQORSA treatment was stopped. A third patient had stable disease without disease progression through 14 courses of treatment (approximately 10 months) before disease progression and is no longer receiving treatment. The results of the Phase 1 dose escalation portion of the study were published in Clinical Lung Cancer, a peer-reviewed journal covering various aspects of clinical and translational research of lung cancer, in January 2026. We opened the Phase 2a expansion portion of the study and enrolled and dosed the first patient in January 2024. The Phase 2a expansion portion of the trial is expected to enroll approximately 33 patients, all of whom had disease progression on Tagrisso or Tagrisso-containing regimens. There will be an interim analysis following the treatment of 19 patients in the Phase 2a portion of the Acclaim-1 study. We expect to complete the enrollment of the first 19 patients for interim analysis in the Phase 2a expansion portion of the study in the first half of 2026 and expect the interim analysis in the second half of 2026.

The Phase 2a expansion portion of the Acclaim-1 study provides us the advantage of early insight into drug effectiveness in defined and distinct patient populations at the maximum tolerated dose or RP2D in order to better evaluate efficacy and increase the likelihood of a successful randomized Phase 2 trial which will follow the expansion portion of the study.

Acclaim – 3: The Acclaim-3 study has two portions - a Phase 1 dose escalation portion and a Phase 2 expansion portion. We are currently enrolling and treating patients in the Phase 2 expansion portion of our Phase 1/2 Acclaim-3 clinical trial. The Acclaim-3 clinical trial uses a combination of REQORSA and Genentech, Inc.’s Tecentriq® (atezolizumab) as maintenance therapy for patients with extensive stage small cell lung cancer (“ES-SCLC”) who did not develop tumor progression after receiving Tecentriq and chemotherapy as initial standard treatment. Patients are treated with REQORSA and Tecentriq until disease progression or unacceptable toxicity is experienced. In December 2024, we announced that we had completed the Phase 1 dose escalation portion of the Acclaim-3 clinical trial. Based on full safety data, which showed no DLTs, the Acclaim-3 Safety Review Committee (“Acclaim-3 SRC”) determined that the RP2D of REQORSA will be 0.12 mg/kg administered every 21 days, which was the highest dose level delivered in the Phase 1 portion of the trial, and approved the opening of the Phase 2 expansion portion of the trial. Although decreases in tumor size are not expected during maintenance therapy with atezolizumab alone, there were two patients out of the six enrolled in the Phase 1 dose escalation portion of the study who had marked decreases in measurable disease. We previously reported that the first patient treated in the Phase 1 dose escalation portion of the Acclaim-3 trial had a partial remission, which is defined as at least a thirty percent (30%) decrease in tumor size, from prior to the start of maintenance therapy to the time of the CT scan performed after two cycles of maintenance therapy. A CT scan performed after four cycles of maintenance therapy (three months), confirmed that the patient still had a 30% decrease in tumor size in measurable lesions; however, one lesion not previously measurable had grown in size, thus leading to a conclusion of disease progression at that time. Another patient in the Phase 1 dose escalation portion of the Acclaim-3 trial had a twenty-three percent (23%) decrease in tumor size from prior to the start of maintenance therapy to the time of the CT scan performed after two cycles of maintenance therapy. This patient received seven cycles of study therapy before progressing after 4.2 months. In addition, one patient in the Phase 1 dose escalation portion of the study achieved an unconfirmed partial remission after 24 cycles of therapy and continues to receive study treatment in the trial after more than 19 months. We anticipate that the Phase 2 expansion portion will enroll approximately 50 patients at approximately 10 to 15 U.S sites. Patients will be treated with REQORSA and Tecentriq until disease progression or unacceptable toxicity is experienced. The primary endpoint of the Phase 2 portion is to determine the 18-week progression-free survival rate from the start of maintenance therapy with REQORSA and Tecentriq in patients with ES-SCLC. Patients will also be followed for survival. A Phase 2 futility analysis will be performed after the 25th patient enrolled and treated reaches 18 weeks of follow up. We expect to complete enrollment of the first 25 patients for interim analysis in the Phase 2 expansion portion of the study in the first half of 2026 and expect the interim analysis in the second half of 2026.

The Acclaim-3 clinical trial has received FDA Fast Track Designation for this patient population and Acclaim-3 has also received an FDA Orphan Drug Designation.

Diabetes Gene Therapy

In diabetes, we have exclusively licensed from the University of Pittsburgh of the Commonwealth System of Higher Education (“University of Pittsburgh” or “UP”) multiple technologies relating to the development of a gene therapy product for each of Type 1 and Type 2 diabetes. The same novel approach is used in each of Type 1 and Type 2 diabetes whereby an adeno-associated virus (“AAV”) vector containing the Pdx1 and MafA genes is administered directly into the pancreatic duct. In humans, this can be done with a routine endoscopy procedure. Our diabetes product candidates are currently being evaluated and optimized in preclinical studies at the University of Pittsburgh. GPX-002 is being developed for the treatment of both Type 1 diabetes and Type 2 diabetes. GPX-002 for Type 1 diabetes is designed to work by transforming alpha cells in the pancreas into functional beta-like cells, which can produce insulin but may be distinct enough from beta cells to evade the body’s immune system. In a similar approach, GPX-002 for Type 2 diabetes, where autoimmunity is not at play, is believed to work by replenishing and rejuvenating exhausted beta cells that make insulin. We are currently working with the University of Pittsburgh on species analyses for the animal models as well as other regulatory and clinical strategic planning, including the initiation of research in Type 2 diabetes animal models. In December 2025, we also executed on our strategic goal to submit a meeting request to the FDA by the end of the year to discuss the necessary Investigational New Drug (“IND”)-enabling preclinical studies, an important step before potentially initiating clinical trials in humans. See the discussion captioned “Recent Developments – Diabetes Gene Therapy Updates” below for more information on the Company’s meeting with the FDA which occurred in February 2026. In May 2025, following the completion of our August 2022 sponsored research agreement with UP, we entered into a new sponsored research agreement with UP to study Type 1 diabetes and Type 2 diabetes in animal models. The new sponsored research agreement also includes a revised research plan to encompass our most recent technologies to which we originally acquired exclusive rights from UP in July 2023 as amended and restated in the comprehensive New UP License Agreement in February 2025 (as defined and described below). These include a MafB promoter to drive expression of the Pdx1 and MafA transcription factors that can potentially be used for both Type 1 and Type 2 diabetes. See also “Note 6 – Commitments and Contingencies” to our unaudited condensed consolidated financial statements in this Quarterly Report on Form 10-Q.

On February 17, 2025, we and the University of Pittsburgh entered into an amended and restated Exclusive License Agreement (the “New UP License Agreement”), which updated and consolidated into a single agreement our prior license agreements with UP. Pursuant to the New UP License Agreement, UP granted to us a worldwide, exclusive license for certain patents and related technology, collectively referred to as the “Licensed Technology,” and a worldwide, non-exclusive license to use certain related know-how. The Licensed Technology covered by the New UP License Agreement is based on the same general gene therapy approach as covered under our prior license agreements with UP (less the previously-licensed macrophage technology), whereby an adeno-associated virus vector containing the Pdx1 and MafA genes is administered directly into the pancreatic duct. More specifically, the Licensed Technology covered by the New UP License Agreement is related to a gene therapy for both Type 1 diabetes and Type 2 diabetes using the genes of the Pdx1 and MafA transcription factors controlled by insulin, glucagon and MafB promoters.

In February 2023, our research collaborators at UP presented preclinical data in a non-human primate (“NHP”) model of Type 1 diabetes highlighting the therapeutic potential of GPX-002 at the 16th International Conference on Advanced Technologies & Treatments for Diabetes (“ATTD 2023”) in Berlin, Germany. The statistically significant study results showed the treated animals had decreased insulin requirements, increased c-peptide levels, and improved glucose tolerance compared to baseline. In April 2023, the Company hosted a Key Opinion Leader virtual event entitled “Novel Gene Therapy to Treat Type 1 Diabetes,” which discussed preclinical data reported at ATTD 2023 supporting gene therapy to treat Type 1 diabetes. In June 2025, our collaboration partners had two presentations at the 2025 American Diabetes Association (“ADA”) 85th Scientific Sessions. Our research collaborators from UP were invited to give an oral presentation highlighting their work in NHP models of Type 1 diabetes. In addition, our contract development and manufacturing organization collaborators presented a poster on a non-viral lipid nanoparticle delivery system that would allow a patient to receive multiple treatments.

Recent Developments

Diabetes Gene Therapy Updates

As previously disclosed, in December 2025 we submitted a request to meet with the FDA to discuss the necessary IND-enabling preclinical studies for our Type 1 diabetes gene therapy program, an important step before potentially initiating clinical trials in humans. On February 19, 2026, we met with the FDA and received feedback which aligned with our expectations and plans. Following the FDA meeting and receipt of the official meeting minutes, we plan to continue with preclinical animal studies, as expected, which will allow us to finalize the design and initiate future toxicology studies. Subsequent data from toxicology studies are expected to enable IND filing. Toxicology studies are a required step of drug development, ensuring that new treatments are evaluated in animal models before human use in order to identify potential risks, determine safe dosages and monitor for side effects. Additionally, we plan to begin clinical scale production in a current Good Manufacturing Practices (“cGMP”) compliant facility, allowing us to accelerate our manufacturing processes necessary for IND-enabling preclinical studies and clinical trials. We are also continuing work with third-party contract development and manufacturing organizations (“CDMOs”) and research partners to optimize constructs and evaluate alternative second-generation approaches including different AAV and non-viral constructs.

At-the-Market Offering Program

On December 13, 2023, we entered into an At The Market (“ATM”) Offering Agreement (the “Sales Agreement”) with H.C. Wainwright & Co., LLC, serving as agent (the “Agent”) with respect to an ATM offering program (the “2023 ATM Facility”) under which we may offer and sell through the Agent, from time to time at our sole discretion, up to such number or dollar amount of shares (the “Shares”) of our common stock, as registered on the prospectus supplement covering the 2023 ATM Facility offering, as may be amended or supplemented from time to time, including pursuant to any new or successor registration statement that we may file and such applicable prospectuses and prospectus supplements forming a part thereof. We have agreed to pay the Agent a commission equal to three percent (3%) of the gross sales proceeds of any Shares sold through the Agent under the Sales Agreement, and also have provided the Agent with customary indemnification and contribution rights. From April 1, 2026 through the date of filing of this Quarterly Report on Form 10-Q, we have sold 1,536,546 Shares of our common stock for net proceeds to us totaling approximately $1.90 million through the Agent under the Sales Agreement.

Recently Issued Accounting Pronouncements

A description of recently issued accounting pronouncements that may potentially impact our financial position and results of operations is disclosed below and in Note 2 to our unaudited condensed consolidated financial statements appearing in this Quarterly Report on Form 10-Q.

Critical Accounting Estimates

Our unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the U.S. (“US GAAP”). The preparation of these unaudited condensed consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the unaudited condensed consolidated financial statements, and the reported amounts of expenses incurred during the reporting periods. Our estimates are based on our historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

We believe that the following accounting policies and estimates are the most critical to aid in fully understanding and evaluating our reported financial results, and they require our most difficult, subjective or complex judgments, resulting from the need to make estimates about the effect of matters that are inherently uncertain.

Research and Development Costs

We record accrued expenses for costs invoiced from research and development activities conducted on our behalf by third-party service providers, which include the conduct of preclinical studies and clinical trials and contract research, manufacturing, and testing activities. We record the costs of research and development activities based upon the amount of services provided, and we include these costs in accrued liabilities in the unaudited condensed consolidated balance sheets and within research and development expense in the unaudited condensed consolidated statements of operations. These costs are a significant component of our research and development expenses. Purchased materials to be used in future research are valued at cost and capitalized and included in research and development supplies. The costs of materials that were acquired for a particular research and development activity and have no alternative future use are expensed in the period acquired.

We estimate the amount of work completed through discussions with internal personnel and external service providers as to the progress or stage of completion of the services and the agreed-upon fee to be paid for such services. We make significant judgments and estimates in determining the accrued balance in each reporting period. As actual costs become known, we adjust our accrued estimates. Although we do not expect our estimates to be materially different from amounts actually incurred, our understanding of the status and timing of services performed, the number of patients enrolled and the rate of patient enrollment in any of our clinical trials may vary from our estimates and could result in our reporting amounts that are too high or too low in any particular period. Our accrued expenses are dependent, in part, upon the receipt of timely and accurate reporting from contract research organizations (“CROs”) and other third-party service providers.

Income Taxes

Deferred tax assets or liabilities are recorded for temporary differences between financial statement and tax basis of assets and liabilities, using applicable rates in effect for the year in which the differences are expected to reverse. A valuation allowance is recorded if it is more likely than not that a deferred tax asset will not be realized. We have provided a full valuation allowance on our deferred tax assets, which primarily consist of cumulative net operating losses from April 1, 2009 (inception) to March 31, 2026. Due to our history of operating losses since inception and losses expected to be incurred in the foreseeable future, a full valuation allowance was considered necessary.

Impairment of Long-Lived Assets

Management evaluates long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount may not be realizable or at a minimum annually during the fourth quarter of the year. If an evaluation is required, the estimated future undiscounted cash flows associated with the asset are compared to the asset’s carrying value to determine if an impairment of such asset is necessary. The effect of any impairment would be to expense the difference between the fair value of such asset and its carrying value based upon discounted cash flows.

Components of our Results of Operations and Financial Condition

Operating expenses

We classify our operating expenses into three categories: research and development, general and administrative, and depreciation.

Research and development. Research and development expenses consist primarily of:

	•	costs incurred to conduct research, such as the discovery and development of our current and potential product candidates;
	•	costs related to the production and storage of supplies for engineering purposes and storage and usage of clinical supplies, including waste created in the process of producing clinical materials, spoilage, and testing of clinical materials;
	•	costs related to the use of contract manufacturers, manufacturing consultants, testing organizations, cold-storage facilities, and logistics service providers;
	•	fees paid to clinical consultants, clinical trial sites and vendors, including CROs in conjunction with implementing and monitoring our clinical trials and acquiring and evaluating clinical trial data, including all related fees, such as patient screening fees, laboratory work, and statistical compilation and analysis;
	•	costs related to compliance with drug development regulatory requirements; and
	•	costs related to staffing and personnel associated with research and development activities, including wages, taxes, benefits, leases, overheads, supplies, and share-based compensation.

We recognize all research and development costs as they are incurred except those capitalized with alternative further use. Clinical trial costs, contract manufacturing and other development costs incurred by third-parties are expensed as the contracted work is performed.

We expect our research and development expenses to increase in the future as we (i) advance our current and future product candidates into and through clinical trials, (ii) transition some of our manufacturing activities to new vendors for a variety of reasons, such as to incorporate more advanced processes and scale production, including any additional work that has been or may be required to successfully adapt our process to these new processes, (iii) pursue regulatory approval of our current and potential product candidates in the U.S. and Europe, and (iv) expand our research programs to include new therapies and new therapy combinations. The process of conducting the necessary pre-clinical and clinical research to obtain regulatory approval is costly and time-consuming. The actual probability of success for our current and potential product candidates may be affected by a variety of factors including the quality of our current and potential product candidates, early clinical data, investment in our clinical program, competition, manufacturing capability and commercial viability, and limited contracted partners. We may never succeed in achieving regulatory approval for any of our current or future product candidates. As a result of the uncertainties discussed above, we are unable to determine the duration and completion costs of our research and development projects or when and to what extent we will generate revenue from the commercialization and sale of our product candidates, if at all. However, we continue to evaluate ways to optimize our clinical and research programs and operational strategies, as part of our ongoing prioritization initiative. Additionally, we are considering various strategic alternatives and opportunities to enhance stockholder value.

General and administrative. General and administrative expense consists of personnel related costs, which include administrative and executive salaries, as well as the costs of professional services, such as accounting and legal, travel, facilities, information technology and other administrative expenses. We expect our general and administrative expense to increase in future periods due to the anticipated growth of our business and related infrastructure as well as accounting, insurance, investor relations, and other costs associated with being a public company.

Depreciation. Depreciation expense consists of depreciation from our fixed assets consisting of our property, equipment, and furniture. We depreciate our assets over their estimated useful life. We estimate furniture and computer and office equipment to have a three to five year life.

Results of Operations

Comparison of the Three Months Ended March 31, 2026 and 2025

The following summarizes our results of operations for the three months ended March 31, 2026 and 2025.

Research and Development Expense

Research and development (“R&D”) expense for the three months ended March 31, 2026 was $2,745,945, compared to $2,539,993 for the three months ended March 31, 2025, an increase of $205,952, or 8%. This increase was primarily due to (i) differences in enrollment rates and administration of services associated with the Acclaim-1 and Acclaim-3 clinical trials during each of the periods, (ii) a slight increase in manufacturing of clinical materials and research materials, (iii) a slight increase in preclinical research and R&D discovery programs, and (iv) increase in R&D overheads associated with the accrual of bonuses.

General and Administrative Expense

General and administrative (“G&A”) expense for the three months ended March 31, 2026 was $1,748,239, compared to $1,429,299 for the three months ended March 31, 2025, an increase of $318,940, or 22%. This increase was primarily due to (i) an increase in corporate franchise tax expense as a result of the one-for-fifty (1:50) reverse stock split of our issued and outstanding shares of common stock effected on October 21, 2025 (the “2025 Reverse Split”), (ii) a slight increase in the expense amount associated with professional service providers, and (iii) an increase in G&A overheads associated with the accrual of bonuses.

Other Income. Other income was $31,748 and $4,771 for the three months ended March 31, 2026 and 2025, respectively, representing an increase of $26,977. The increase was primarily due to larger cash balances held in interest bearing accounts for the three months ended March 31, 2026 compared to the three months ended March 31, 2025.

Depreciation Expense. There was no depreciation expense for the three months ended March 31, 2026 and March 31, 2025.

Net Loss. We had a net loss of $4,461,895 and $3,964,601 for the three months ended March 31, 2026 and 2025, respectively, representing an increase of $497,294, or 13%. The increase in net loss between these periods was primarily due to (i) differences in enrollment rates and administration of services associated with the Acclaim-1 and Acclaim-3 clinical trials during each of the periods, (ii) a slight increase in manufacturing of clinical materials and research materials, (iii) a slight increase in preclinical research and R&D discovery programs, (iv) increase in R&D and G&A overheads associated with the accrual bonuses, (v) an increase in corporate franchise tax expense as a result of the 2025 Reverse Split, and (vi) a slight increase in the expense amount associated with professional service providers.

Liquidity and Capital Resources

From inception through March 31, 2026, we have never generated revenue from product sales and have incurred net losses in each year. As of March 31, 2026, we had an accumulated deficit of $175,490,291. We have funded our operations primarily through the sale and issuance of capital stock.

During the three months ended March 31, 2026, we sold 5,714,798 Shares of common stock for aggregate gross proceeds of approximately $13.80 million (resulting in aggregate net proceeds of approximately $13.36 million after offering expenses), pursuant to our 2023 ATM Facility. From April 1, 2026 through the date of filing of this Quarterly Report on Form 10-Q, we sold 1,536,546 Shares of common stock for aggregate gross proceeds of approximately $1.96 million (resulting in aggregate net proceeds of approximately $1.90 million after offering expenses), pursuant to our 2023 ATM Facility.

For the year ended December 31, 2025, we sold (i) 1,602,490 Shares of common stock for net proceeds of approximately $10.8 million pursuant to our 2023 ATM Facility, (ii) 772,867 shares of common stock (inclusive of the 23,737 commitment shares issued pursuant to the Purchase Agreement (as defined below)) for aggregate net proceeds of approximately $5.3 million, pursuant to our 2025 ELOC Facility (as defined below), (iii) completed a registered direct offering in which we sold (x) 243,622 shares of our common stock, and (y) warrants exercisable for up to an aggregate of 487,244 shares of our common stock (“October 2025 Private Warrant Shares I”), for net proceeds of approximately $2.5 million, and (iv) completed a registered direct offering in which we sold (x) 377,780 shares of our common stock, and (y) warrants exercisable for up to an aggregate of 755,560 shares of our common stock (“October 2025 Private Warrant Shares II”), for net proceeds of approximately $3.1 million. See also “Note 4 - Equity - Registered Direct Offerings” to our unaudited condensed consolidated financial statements included in this Quarterly Report on Form 10-Q.

On June 11, 2025, we entered into an equity line of credit (“ELOC”) purchase agreement, dated June 11, 2025 (the “Purchase Agreement”), with Lincoln Park Capital Fund, LLC (“Lincoln Park”), pursuant to which Lincoln Park committed to purchase from us up to $12.5 million in shares of our common stock (subject to certain conditions and limitations contained in the Purchase Agreement) from time to time at our sole discretion over the 24-month term of the Purchase Agreement (the “2025 ELOC Facility”). Sales of shares of common stock to Lincoln Park under the Purchase Agreement will depend on a variety of factors to be determined by us from time to time, including, among others, market conditions, the trading price of our common stock and our determination as to the appropriate sources of funding for our operations. See also “Note 4 - Equity – Equity Line of Credit” to our unaudited condensed consolidated financial statements included in this Quarterly Report on Form 10-Q.

On December 13, 2023, we entered into an At The Market (“ATM”) Offering Agreement (the “Sales Agreement”) with H.C. Wainwright & Co., LLC, serving as agent (the “Agent”) with respect to an at-the-market offering program (our “2023 ATM Facility”) under which we may offer and sell through the Agent, from time to time at our sole discretion, up to such number or dollar amount of shares of our common stock (the “Shares”) as registered on the prospectus supplement covering the 2023 ATM Facility offering, as may be amended or supplemented from time to time, including any new or successor registration statement that we may file and such applicable prospectuses and prospectus supplements forming a part thereof. We have agreed to pay the Agent a commission equal to three percent (3%) of the gross sales proceeds of any Shares sold through the Agent under the Sales Agreement, and also have provided the Agent with customary indemnification and contribution rights. See also “Note 4 - Equity - At-The-Market Offering” to our unaudited condensed consolidated financial statements included in this Quarterly Report on Form 10-Q.

Table of Contents

As of March 31, 2026, we had $18,049,255 in cash and cash equivalents.

We do not expect to generate revenue from product sales unless and until we successfully complete development of, obtain regulatory approval for and begin to commercialize one or more of our current or future product candidates, which we expect will take a number of years and which is subject to significant uncertainty. Accordingly, we anticipate that we will need to raise additional capital to fund our future operations, which include conducting our Acclaim-1 and Acclaim-3 clinical trials (of which both are currently enrolling) and completing preclinical work for potential other oncology candidates and completing preclinical work and conducting clinical trials for our diabetes program. We expect interim enrollment of the Phase 2a expansion portion of the Acclaim-1 trial to be completed in the first half of 2026. We expect interim enrollment in the Phase 2 dose expansion portion of the Acclaim-3 trial to be completed in the first half of 2026. Until such time as we can generate substantial revenue from product sales, if ever, we expect to finance our operating activities through a combination of equity offerings, drawdowns on our 2023 ATM Facility pursuant to our Sales Agreement with the Agent, sales pursuant to our 2025 ELOC Facility, and debt financings and we may seek to raise additional capital through strategic collaborations or transactions. However, we may be unable to raise additional funds or enter into such arrangements when needed on favorable terms, or at all, which would have a negative impact on our financial condition and could force us to delay, limit, reduce or terminate our research and development programs or commercialization efforts or grant rights to others to develop or market product candidates that we would otherwise prefer to develop and market ourselves. Failure to receive additional funding could cause us to curtail or cease our operations. Furthermore, even if we believe we have sufficient funds for our current or future operating plans, we may seek additional capital due to favorable market conditions or strategic considerations. As a result of our recurring losses from operations and the need for additional financing to fund our operating and capital requirements, there is uncertainty regarding our ability to maintain liquidity sufficient to operate our business effectively over the next 12 months, which raises substantial doubt as to our ability to continue as a going concern.

Based on our current cash, we estimate that we will be able to fund our expenditure requirements for our current operations and planned clinical trial activities into the second half of 2027. We have based these estimates on assumptions that may prove to be wrong, and we could utilize our available capital resources sooner than we currently plan due to incorrect assumptions or due to a decision to expand our activities beyond those currently planned. We have experienced delays in clinical trial enrollment as a result of competition for patients and previously experienced delays due to additional time required in connection with transitions to new third party CDMOs and the manufacture of final drug product. Delays in the conduct of our trials could result in utilizing our capital resources sooner without advancing our clinical trials as anticipated.

The following table sets forth the primary sources and uses of cash during the three months ended March 31, 2026, and 2025:

	Three Months Ended March 31,
	2026			2025
Net cash used in operating activities	$	(3,138,457	)	$	(4,161,424	)
Net cash used in investing activities		—			—
Net cash provided by financing activities		13,356,857			6,028,102
Net increase in cash and cash equivalents	$	10,218,400		$	1,866,678

Cash used in operating activities

Net cash used in operating activities was $3,138,457 and $4,161,424 for the three months ended March 31, 2026, and 2025, respectively, a decrease of $1,022,967, or 25%. This decrease was primarily due to (i) an increase in R&D materials and accounts payable associated with operating activities, and (ii) differences in the timing associated with the payment of certain operating activities between the three months ended March 31, 2026, and 2025.

Cash provided by investing activities

We had no net cash provided by or used in investing activities for the three months ended March 31, 2026, and 2025.

Cash provided by financing activities

Net cash provided by financing activities was $13,356,857 and $6,028,102 during the three months ended March 31, 2026, and 2025, respectively. This increase of $7,328,755 was primarily due to differences in amounts raised by sales of our securities in capital raising activities conducted during the three months ended March 31, 2026, and 2025.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

The Company is not required to provide the information called for by this Item as it is a “smaller reporting company,” as defined in Rule 12b-2 of the Exchange Act.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

As required by Rules 13a-15(b) and 15d-15(b) of the Exchange Act, our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as of March 31, 2026. The term “disclosure controls and procedures” as defined in Rules 13a-15(e) and 15d-15(e) under 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 a company’s management, including its principal executive and principal financial officer, as appropriate to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives, and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on the evaluation of our disclosure controls and procedures as of March 31, 2026, our Chief Executive Officer and Chief Financial Officer concluded that, as of such date, our disclosure controls and procedures were not effective due to material weaknesses in our internal control over financial reporting related to a lack of segregation of duties between accounting and other functions and the absence of sufficient depth of in-house accounting personnel with the ability to properly account for complex transactions.

Due to our size and nature, segregation of all conflicting duties may not always be possible and may not be economically feasible. However, to the extent possible, the initiation of transactions, the custody of assets and the recording of transactions should be performed by separate individuals. Our size and nature also do not allow for our accounting staff to have depth of expertise in all areas that might be desirable, such as expertise in accounting for a variety of complex transactions. Management evaluated the impact of our failure to maintain effective segregation of duties and sufficient depth of personnel on our assessment of our internal control over financial reporting and has concluded that these control deficiencies represent material weaknesses.

In response to the material weaknesses described above, during the quarter ended March 31, 2026, we performed additional analysis and other post-closing procedures to ensure our financial statements were prepared in accordance with US GAAP. Accordingly, we believe that the financial statements included in this report fairly present, in all material respects, our financial condition, results of operations and cash flows for the periods presented.

Remediation Plans

Management is actively engaged in remediation efforts to address the material weaknesses identified in management’s evaluation of internal controls and procedures. The remediation efforts, which have been or are in the process of being implemented, are intended to address the identified material weaknesses, and include:

•

new accounting software, processes, and workflows to further segregate duties among limited accounting staff;

•

specific review procedures, including the added involvement of our legal department to review certain accounting transactions following a given period in an effort to enhance accuracy of reporting;

•

specific review procedures, including the added involvement of our manufacturing staff to enhance controls associated with the tracking and reporting of inventory values in our supply chain;

•

a formal Disclosure Committee that has oversight responsibility for the accuracy and timeliness of disclosures made by the Company through controls and procedures and the monitoring of their integrity and effectiveness;

	•	additional hiring of staff and development of accounting processes and policies to further segregate accounting responsibilities and increase the depth of our expertise in accounting for a variety of complex transactions; and

	•	additional training, testing, and certification of key accounting, finance, IT, and legal team members.

During the quarter ended March 31, 2026, we took actions to remediate the material weaknesses relating to our internal controls over financial reporting including: (i) continued evaluation and documentation of policies, processes, and controls, both manual and automated; (ii) identification and implementation of improvements to information technology and security controls and supporting control documentation; and (iii) evaluation of and updates to software workflows to further segregate duties, enhance accuracy of vendor billing, and ensure transparency and oversight from vendor or project managers, department leaders, legal team members, and finance team members.

As management continues to evaluate and work to improve its internal control over financial reporting, we may take additional measures to address control deficiencies, or we may modify certain of the remediation measures described above. While remediation efforts are active, management requires additional time to demonstrate the operating effectiveness of our remediation efforts. The material weaknesses cannot be considered remediated until the applicable remedial controls operate for a sufficient period of time and management has concluded, through testing, that these controls are operating effectively.

Changes in Internal Control over Financial Reporting

Except as described above, there were no changes in our internal control over financial reporting during the quarter ended March 31, 2026, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Inherent Limitations of Disclosure Controls and Internal Control over Financial Reporting

Because of their inherent limitations, our disclosure controls and procedures and our internal control over financial reporting may not prevent material errors or fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. The effectiveness of our disclosure controls and procedures and our internal control over financial reporting is subject to risks, including that the controls may become inadequate because of changes in conditions or that the degree of compliance with our policies or procedures may deteriorate.

PART II – OTHER INFORMATION

Item 1. Legal Proceedings

From time to time, we may be involved in legal proceedings that arise during the ordinary course of business. Although the results of legal proceedings cannot be predicted with certainty, we do not currently have any pending litigation to which we are a party or to which our property is subject that we believe to be material. Regardless of the outcome, litigation can be costly and time consuming, and it can divert management’s attention from important business matters and initiatives, negatively impacting our overall operations.

Item 1A. Risk Factors

The Company is not required to provide the information called for by this Item as it is a “smaller reporting company,” as defined in Rule 12b-2 of the Exchange Act.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

During the three months ended March 31, 2026, we issued and sold the following unregistered securities:

On January 2, 2026, we issued 5,000 shares of our common stock to the Chairman of our Scientific Advisory Board in consideration for services during the three months ended March 31, 2026.

The foregoing issuance of securities was not registered under the Securities Act or the securities laws of any state, and the securities were offered and issued in reliance on the exemption from registration under the Securities Act afforded by Section 4(a)(2).

Item 3. Defaults Upon Senior Securities

None.

Item 4. Mine Safety Disclosures

Not applicable.

Item 5. Other Information

Rule 10b5-1 Trading Arrangements and Non-Rule 10b5-1 Trading Arrangements

During the fiscal quarter ended March 31, 2026, none of our officers or directors, as those terms are defined in Rule 16a-1(f), adopted or terminated a “Rule 10b5-1 trading arrangement” or a “non-Rule 10b5-1 trading arrangement,” as those terms are defined in Item 408 of Regulation S-K.
