Item 3.03. Material Modification to Rights of Security Holders.

To the extent required by Item 3.03 of Form 8-K, the information regarding the Reverse Stock Split (as defined below) contained in Item 5.03 of this Current Report on Form 8-K is incorporated by reference herein.

Item 5.03. Amendments to Articles of Incorporation or Bylaws; Change in Fiscal Year.

On July 13, 2026, Genprex, Inc. (“Genprex” or the “Company”) filed a Certificate of Amendment to the Company’s Amended and Restated Certificate of Incorporation, as amended, with the Secretary of State of the State of Delaware (the “Certificate of Amendment”), which will effect, at 12:01 a.m. Eastern Time on July 16, 2026, a one-for-twenty-two (1:22) reverse stock split (the “Reverse Stock Split”) of the Company’s issued and outstanding shares of common stock, par value $0.001 per share (the “Common Stock”). In connection with the Reverse Stock Split, the CUSIP number for the Common Stock will change to 372446-401. The trading symbol for the Company’s common stock will remain “GNPX”.

The Company anticipates the Common Stock will begin trading on a Reverse Stock Split-adjusted basis when the market opens on July 16, 2026.

As a result of the Reverse Stock Split, every twenty-two (22) shares of Common Stock issued and outstanding will be converted into one (1) share of Common Stock. The Reverse Stock Split will affect all stockholders uniformly and will not alter any stockholder’s percentage interest in the Company’s equity, except to the extent that the Reverse Stock Split would result in some stockholders owning a fractional share. No fractional shares will be issued in connection with the Reverse Stock Split. Stockholders who would otherwise be entitled to a fractional share of Common Stock will automatically be entitled to receive an additional fraction of a share of Common Stock to round up to the next whole share. Based on 11,108,577 shares of Common Stock outstanding as of July 13, 2026, the Company estimates that immediately after giving effect to the Reverse Stock Split (and prior to any rounding applied to any fractional shares that would result from the Reverse Stock Split, and without taking into account any additional shares that may be issued subsequent to July 13, 2026), the Company will have approximately 504,936 shares of Common Stock outstanding.

The Reverse Stock Split will not change the par value of the Common Stock or the authorized number of shares of Common Stock. All outstanding securities entitling their holders to purchase shares of Common Stock or acquire shares of Common Stock, including stock options and warrants, will be adjusted as a result of the Reverse Stock Split, as required by the terms of those securities.

At the Company’s annual meeting of stockholders held on June 18, 2026, the Company’s stockholders granted the Company’s Board of Directors (the “Board”) the discretion to effect the Reverse Stock Split at a ratio of not less than one-for-five (1:5) and not more than one-for-fifty (1:50), with such ratio to be determined by the Board. On July 2, 2026, the Board approved a Reverse Stock Split ratio of one-for-twenty-two (1:22) and authorized the filing of the Certificate of Amendment.

The foregoing description of the Certificate of Amendment is a summary of the material terms thereof, does not purport to be complete and is qualified in its entirety by reference to the full text of the Certificate of Amendment, which is filed with this report as Exhibit 3.1 and is incorporated herein by reference.

Item 8.01. Other Events.

The Company’s investor presentation provides certain business updates, including on its oncology and diabetes gene therapy programs.

Acclaim-1 Clinical Trial

The Acclaim-1 study is a Phase 1/2 clinical trial that has three portions - a Phase 1 dose escalation portion which has been completed, a Phase 2a expansion portion, and a Phase 2b randomized portion. We are currently 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 non-small cell lung cancer (“NSCLC”) who have activating epidermal growth factor receptor (“EGFR”) mutations and disease progression on treatment with Tagrisso or Tagrisso-containing regimens. 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”), including one patient who achieved a partial response after the second course of REQORSA and Tagrisso and remained on treatment without disease progression for approximately 46 months. 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. The Acclaim-1 clinical trial has received U.S. Food and Drug Administration (“FDA”) Fast Track Designation for the Acclaim-1 treatment combination of REQORSA and Tagrisso in NSCLC patients who have progressed after Tagrisso treatment.

As previously announced, in April 2026, we entered into a new sponsored research agreement with the University of Texas MD Anderson Cancer Center to study biomarkers that may predict patient response to REQORSA. This preclinical effort led to the identification of two proteins, TROP-2 and PTEN, whose expression appears to predict response to REQORSA. These preclinical data indicated that NSCLC cells with high TROP-2 protein levels or low PTEN protein levels had greater response to REQORSA. In May 2026, an abstract was published by our research collaborators at the 2026 American Society of Clinical Oncology (ASCO) Annual Meeting which detailed positive clinical data from studies of predictive biomarkers in patients receiving REQORSA. This clinical validation, derived from patients in our Acclaim clinical trials, underscores the critical role these biomarkers may play in predicting treatment efficacy. These data advance our understanding of this novel gene therapy and may help to guide patient selection for our clinical trials and optimize clinical outcomes. We plan to further evaluate high (3+) TROP-2 expression as a potential biomarker for REQORSA, which may predict patient response and enable targeted patient selection. We are currently evaluating enrollment criteria based on biomarker identification prior to any potential future interim analysis as we continue to enroll and treat patients in the Phase 2a expansion portion of our Acclaim-1 clinical trial.

Acclaim-3 Clinical Trial

The Acclaim-3 study is a Phase 1/2 clinical trial that has two portions - a Phase 1 dose escalation portion which has been completed, 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. 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 by the end of 2026 and expect the interim analysis in the first half of 2027. 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.

Risk Factors

The Company is including the below update to its risk factors, for the purpose of supplementing and updating the “Risk Factors” disclosure contained in its Annual Report on Form 10-K for the fiscal year ended December 31, 2025, filed with the Securities and Exchange Commission on March 30, 2026, the Company’s Quarterly Report on Form 10-Q for the fiscal quarter ended March 31, 2026, filed with the Securities and Exchange Commission on May 13, 2026, as further supplemented and updated in the Company’s other periodic and current reports filed from time to time since such Annual Report on Form 10-K.

Our Common Stock is currently listed on The Nasdaq Capital Market. If we fail to regain compliance with the continued listing requirements of Nasdaq, our common stock may be delisted and the price of our common stock and our ability to access the capital markets could be negatively impacted.

Our Common Stock is currently listed for trading on Nasdaq. On June 10, 2026, we received a letter from Nasdaq indicating that, based upon our lack of compliance with the with the requirement under Nasdaq Listing Rule 5550(a)(2) to maintain a minimum bid price of $1.00 per share for continued listing on Nasdaq (the “Bid Price Requirement”) and our ineligibility for a 180 calendar day compliance period, the Listing Qualifications Staff of Nasdaq (the “Staff”) had determined to delist our securities from Nasdaq unless we timely request a hearing before a Nasdaq Hearings Panel (the “Panel”). Accordingly, Genprex has so requested a hearing before the Panel. Our request for a hearing automatically stayed any suspension or delisting action by the Staff pending the hearing and the expiration of any additional extension period that may be granted by the Panel following the hearing. We intend to continue to take definitive steps in an effort to evidence compliance with the Bid Price Requirement; however, there can be no assurance that the Panel will grant our request for continued listing or that we will be able to evidence compliance with the Bid Price Requirement within any extension period that may be granted by the Panel, or that we will be able to maintain compliance with the Bid Price Requirement or the other Nasdaq continued listing requirements.

We intend to continue to monitor the closing bid price of our Common Stock and take definitive steps in an effort to evidence and regain compliance with the Bid Price Requirement, including by implementing effective July 16, 2026 the one-for-twenty-two (1:22) Reverse Stock Split of our Common Stock. To regain compliance with the Bid Price Requirement, the closing bid price of our Common Stock must be at least $1.00 for a minimum of 10 consecutive business days, subject to the Panel’s discretion to extend such 10-day period. The announcement and implementation of the Reverse Stock Split could negatively affect the price of our Common Stock, and there is no guarantee that implementation of the Reverse Stock Split will result in our regaining compliance with the Bid Price Requirement. We cannot assure you that the prices for shares of the Common Stock after the Reverse Stock Split will increase proportionately to prices for shares of our Common Stock immediately before the Reverse Stock Split. Furthermore, even if the market price of our Common Stock does rise following the Reverse Stock Split, we cannot assure you that the market price of our Common Stock immediately after the Reverse Stock Split will be maintained for any period of time. There is also the possibility that liquidity may be adversely affected by the reduced number of shares which would be issued and outstanding when the Reverse Stock Split is effected, particularly if the price per share of our Common Stock begins a declining trend after the Reverse Stock Split is effected. Accordingly, our total market capitalization after the Reverse Stock Split may be lower than the market capitalization before the Reverse Stock Split.

We must regain compliance with Nasdaq’s Bid Price Requirement of $1.00 per share (and must continue to maintain compliance with Nasdaq’s other continued listing requirements), or risk delisting, which could have a material adverse effect on our business. If our Common Stock is delisted from Nasdaq, it could result in a corresponding material reduction in the price of our Common Stock as a result of the loss of market efficiencies associated with Nasdaq and the loss of federal preemption of state securities laws. In addition, delisting could harm our ability to raise capital through alternative financing sources on terms acceptable to us, or at all, and may result in the potential loss of confidence by investors, suppliers, contractual counterparties and employees and fewer business development opportunities. If our Common Stock were delisted, it could be more difficult to buy or sell our Common Stock or to obtain accurate quotations, and the price of our Common Stock could suffer a material decline. Delisting could also impair our ability to raise capital on acceptable terms, if at all.

OF
GENPREX, INC.

Genprex, Inc. (the “Company”), a corporation duly organized and validly existing under and by virtue of the General Corporation Law of the State of Delaware (the “DGCL”);

DOES HEREBY CERTIFY AS FOLLOWS:

FIRST: That the Amended and Restated Certificate of Incorporation of the Company (as heretofore amended, the “Amended and Restated Certificate of Incorporation”) is hereby amended as follows:

Article IV of the Amended and Restated Certificate of Incorporation be and hereby is amended by adding, immediately after the seventh paragraph of Section A of Article IV (with the second through fourth paragraphs and fifth through seventh paragraphs of Section A of Article IV having been added to the Amended and Restated Certificate of Incorporation by those certain Certificates of Amendment filed on January 31, 2024 and October 16, 2025, respectively), the following:

“Upon the effectiveness (“Effective Time”) of this amendment to the Certificate of Incorporation, a one-for-twenty-two reverse stock split (the “Reverse Split”) of the Company’s Common Stock shall become effective, pursuant to which each twenty-two (22) shares of Common Stock outstanding and held of record by each stockholder of the Company or held in treasury by the Company immediately prior to the Effective Time (“Old Common Stock”) shall automatically, and without any action by the holder thereof, be reclassified and combined into one (1) validly issued, fully paid and non-assessable share of Common Stock (“New Common Stock”), subject to the treatment of fractional interests as described below and with no corresponding reduction in the number of authorized shares of Common Stock. The Reverse Split shall also apply to any outstanding securities or rights convertible into, or exchangeable or exercisable for, Old Common Stock and all references to such Old Common Stock in agreements, arrangements, documents and plans relating thereto or any option or right to purchase or acquire shares of Old Common Stock shall be deemed to be references to the New Common Stock or options or rights to purchase or acquire shares of New Common Stock, as the case may be, after giving effect to the Reverse Split.

No fractional shares of Common Stock will be issued in connection with the Reverse Split. If, upon aggregating all of the Common Stock held by a holder of Common Stock immediately following the Reverse Split a holder of Common Stock would otherwise be entitled to a fractional share of Common Stock, the Company shall issue to such holder such fractions of a share of Common Stock as are necessary to round the number of shares of Common Stock held by such holder up to the nearest whole share.

Each holder of record of a certificate or certificates for one or more shares of the Old Common Stock shall be entitled to receive as soon as practicable, upon surrender of such certificate, a certificate or certificates representing the largest whole number of shares of New Common Stock to which such holder shall be entitled pursuant to the provisions of the immediately preceding paragraphs. Each stock certificate that, immediately prior to the Effective Time, represented shares of Old Common Stock that were issued and outstanding immediately prior to the Effective Time shall, from and after the Effective Time, automatically and without the necessity of presenting the same for exchange, represent that number of whole shares of New Common Stock after the Effective Time into which the shares formerly represented by such certificate have been reclassified, subject to adjustment for fractional shares as described above.”

SECOND: That the amendment set forth in this Certificate of Amendment was duly adopted by the Board of Directors of the Company and the stockholders of the Company in accordance with Section 242 of the DGCL.

THIRD: That said amendment will have an Effective Time of 12:01 a.m., Eastern Time, on July 16, 2026.
