Incannex Healthcare Inc. Enters Agreement to Cancel Remaining Series A Warrants, Eliminating Up to 347.2 Million Shares from Potential Dilution Ahead of IHL-42X Phase 2 Topline Results

MELBOURNE, Australia and NEW YORK, May 28, 2025 (GLOBE NEWSWIRE) -- Incannex Healthcare Inc. (Nasdaq: IXHL), a clinical-stage biopharmaceutical company advancing combination drug therapies for high-impact indications, today announced that it has entered into a binding agreement to cancel the remaining 172 million Series A Warrants issued under a previous financing arrangement contingent upon Incannex paying the Series A Warrant holders a cancellation payment of up to $12.2 million. When combined with the earlier tranche canceled earlier this month, this agreement will result in the elimination of up to 347.2 million shares from potential future dilution, pending final execution. This strategic step follows the company’s earlier warrant cancellation transaction announced on May 20, 2025, which removed the first 175.2 million dilution-linked shares. With this second agreement now in place, Incannex has taken firm action to fully eliminate the overhang posed by its Series A Warrants. “This is a significant milestone in strengthening our capital structure,” said Joel Latham, President and CEO of Incannex. “Subject to final execution, this transaction ensures that up to 347 million shares will no longer be eligible to enter the market, providing clarity and confidence for our shareholders. It is a strong endorsement of our forward strategy and a clear demonstration that we are actively managing dilution risk with the best interests of our investors in mind.” The agreement comes at a pivotal time for Incannex, as the company approaches the release of topline data from its Phase 2 RePOSA trial of IHL-42X for obstructive sleep apnea, expected in July 2025. IHL-42X is being developed as a potential first-in-class oral pharmaceutical treatment for a condition affecting millions globally, with no current FDA-approved drug therapy available. “We’ve worked quickly and strategically to eliminate overhang and deliver a clean cap table, heading into one of the most important data readouts in the company’s history,” Joel Latham added. “This transaction reflects our proactive approach to value creation and governance.” For more information, please refer to the Form 8-K filed with the SEC on May 28, 2025, including the Letter Agreements referenced therein. About IHL-42X IHL-42X is designed to treat obstructive sleep apnea (“OSA”) by targeting its underlying pathophysiology. An oral fixed-dose combination of dronabinol and acetazolamide, IHL-42X is currently advancing through the RePOSA Phase 2/3 clinical trial, which is expected to enroll more than 560 patients at sites worldwide. Designed to act synergistically, IHL-42X uniquely targets two physiological pathways associated with the intermittent hypoxia (“IH”) and hypercapnia that characterize OSA. In a prior Australian Phase 2 clinical trial, IHL-42X was shown to reduce the Apnea-Hypopnea Index (“AHI”) in all dosage strengths, with the lowest dose reducing AHI by an average of 51 percent relative to baseline. RePOSA, a global Phase 2/3 clinical trial is underway, evaluating IHL-42X in individuals with OSA who are either non-compliant, intolerant, or naïve to positive airway pressure devices, including CPAP, with the Phase 2 portion conducted in the United States. A topline readout from the U.S. Phase 2 portion is anticipated in July 2025. About Incannex Healthcare Inc.
