NEW YORK and MELBOURNE, Australia, May 16, 2025 (GLOBE NEWSWIRE) -- Incannex Healthcare Inc. (Nasdaq: IXHL), ("Incannex”), a clinical-stage biopharmaceutical company leading the way in developing oral combination medicines, announced its entry on May 15, 2025 into agreements with the outstanding holders of its Series A Warrants (the "Letter Agreements”) permitting Incannex to potentially reduce up to 50.4% of the shares of common stock underlying its previously issued Series A Warrants.

The Letter Agreements provide, among other things, Incannex discretion to temporarily utilize its at-the-market sales agreement with A.G.P/Alliance Global Partners (the "ATM”) during a specified period, provided that Incannex uses the first approximately $12.5 million of net proceeds from any placements under the ATM during the specified period to pay the holders of Series A Warrants for the cancellation of up to 5,833,333 shares of common stock underlying the Series A Warrants (which are otherwise subject to adjustment to up to 175,000,000 shares of common stock assuming full adjustment of the exercise price of the Series A Warrant to the floor price of $0.216 per share and exercise pursuant to the zero exercise price provisions of the Series A Warrants).

The Series A Warrants are not presently exercisable as the exercise of the Series A Warrants continues to be subject to obtaining the requisite approval by Incannex's stockholders. Incannex is seeking the requisite stockholder approval at its special meeting of stockholders currently scheduled for May 27, 2025.

"We are pleased to have the opportunity to potentially reduce the dilution to our stockholders from the Series A Warrants,” said Joel Latham, President and CEO of Incannex. "We remain committed to delivering on key upcoming milestones and to advancing IHL-42X as a potential treatment for millions of underserved patients living with obstructive sleep apnea.”

The description of the Letter Agreements above is not complete and is qualified in its entirely by reference to the Current Report on Form 8-K filed by Incannex with the Securities and Exchange Commission on May 15, 2025 and copy of the form of Letter Agreement filed therewith, which we encourage you to review.

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.
