Rhea-AI Filing Summary
Genprex, Inc. approved a one-for-twenty-two Reverse Stock Split of its common stock, effective at 12:01 a.m. Eastern Time on July 16, 2026. Every 22 outstanding shares will convert into 1 share, with fractional positions rounded up to the next whole share. Based on 11,108,577 shares outstanding on July 13, 2026, Genprex estimates about 504,936 shares will be outstanding after the split. The split does not change par value or authorized share count, and outstanding options and warrants will be proportionally adjusted.
The company is using this split as part of efforts to address Nasdaq’s $1.00 minimum bid price requirement after receiving a June 10, 2026 delisting notice and requesting a hearing before a Nasdaq panel. Genprex cautions that the split may not restore compliance and could negatively affect share price, liquidity and market capitalization, with delisting potentially impairing capital-raising ability and overall business.
The company also highlights progress in its REQORSA gene therapy lung cancer program, including ongoing Phase 2 expansion enrollment in the Acclaim-1 and Acclaim-3 trials, FDA Fast Track and Orphan Drug designations, and emerging biomarker data (TROP-2 and PTEN) that may guide patient selection and optimize outcomes.
Positive
- None.
Negative
- Genprex faces Nasdaq delisting risk after a June 10, 2026 notice for failing the $1.00 bid price requirement; loss of listing could materially hurt share price, liquidity, access to capital and broader business prospects if compliance is not regained.

Reverse Stock Split financial
"will effect, at 12:01 a.m. Eastern Time on July 16, 2026, a one-for-twenty-two Reverse Stock Split"
A reverse stock split reduces a company's number of outstanding shares while raising the price per share proportionally, so the total value of each investor's holding is unchanged; a 1-for-10 split turns 100 shares worth $1 each into 10 shares worth $10 each. Companies often do this to regain compliance with an exchange's minimum price rule or to attract investors who avoid very low-priced stocks.
Fast Track Designation regulatory
"Acclaim-1 clinical trial has received U.S. Food and Drug Administration Fast Track Designation"
Fast track designation is a status the U.S. Food and Drug Administration grants to drugs intended to treat serious conditions and address an unmet medical need. It gives the developer more frequent communication with the FDA and can allow parts of the application to be reviewed on a rolling basis, and it may pave the way to priority review or accelerated approval. It can shorten development timelines, though it does not guarantee approval.
Orphan Drug Designation regulatory
"Acclaim-3 has also received an FDA Orphan Drug Designation"
Orphan drug designation is a special status given to medicines developed to treat rare diseases affecting only a small number of people. This status often provides benefits like faster approval processes and financial incentives, making it more attractive for companies to develop these drugs. For investors, it signals potential for exclusive market rights and reduced competition, which can impact the drug’s profitability.
progression-free survival medical
"three patients out of the twelve originally enrolled had prolonged progression-free survival"
Progression-free survival is the length of time during and after a treatment that a patient's disease does not get worse, measured from the start of treatment until the disease shows measurable signs of progression or the patient dies. Investors care because longer progression-free survival in clinical trials often signals that a drug is effective, improving chances of regulatory approval, market adoption, and revenue potential—think of it as a stopwatch showing how long a therapy can keep the illness at bay.
Bid Price Requirement financial
"requirement under Nasdaq Listing Rule 5550(a)(2) to maintain a minimum bid price of $1.00 per share"
A bid price requirement is a rule that specifies the minimum price a buyer must offer per share when making an official purchase proposal, tender offer, auction bid, or similar transaction. It matters to investors because it sets a floor for negotiations and valuation—like a reserve price in an auction—ensuring bids meet regulatory, contract or market standards and helping shareholders and markets judge whether an offer is fair or likely to succeed.

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.

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.
