Incannex Healthcare Inc. Executes Strategic Cancellation of 50.4% of Series A Warrants, Significantly Reducing Potential Dilution

NEW YORK and MELBOURNE, Australia, May 20, 2025 (GLOBE NEWSWIRE) -- Incannex Healthcare Inc. (Nasdaq: IXHL) (“Incannex” or the “Company”), a clinical-stage biopharmaceutical company pioneering the development of combination drug therapies, today announced the successful completion of a $16.7 million gross proceeds capital raise through its at-the-market (ATM) facility. $12.5 million of these proceeds will be used to cancel up to 50.4% of the Series A Warrants previously issued as part of a prior financing agreement.

This strategic initiative significantly reduces potential future dilution attributable to the Series A Warrants, with up to 5,841,038 of these warrants eligible for cancellation. If triggered, the adjustment features of these Series A Warrants could otherwise have resulted in up to 175.2 million additional shares being issued. This move underscores Incannex’s proactive approach to capitalization management and shareholder alignment.

“This is a positive development for Incannex shareholders,” said Joel Latham, President and CEO of Incannex. “We’ve completed a targeted warrant cancellation that eliminates a significant overhang and reduces significant potential dilution from our prior financing. We believe this initiative demonstrates our commitment to responsible capital management and puts shareholders in a stronger position ahead of our Phase 2 IHL-42X results.”

“Following the successful execution of this warrant cancellation, we plan to continue to evaluate further strategic initiatives to continue improving our capital structure. We view this as an important precedent and a signal to the market that we are focused on long-term value creation and protecting shareholder interests.”

This initiative demonstrates Incannex’s continued commitment to shareholder value creation, responsible capital planning, and strengthening of its long-term financial position as it advances its clinical pipeline.

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.
