Item 8.01 Other Events.

On December 18, 2025, Incannex Healthcare Inc. ("we" or the "Company") announced at the 2025 annual meeting of stockholders (the "Annual Meeting") that there were not present or represented by proxy a sufficient number of shares of our common stock to constitute a quorum, primarily due to Proposal No. 2, relating to the ratification of the appointment of its independent registered accounting firm (the "Auditor Ratification Proposal"), being classified as a non-routine proposal because of an administrative error by the Company's transfer agent. Accordingly, we adjourned our Annual Meeting to allow for the solicitation of additional proxies with respect to the proposals set forth in the Proxy Statement. The Annual Meeting has been adjourned to Thursday, January 15, 2026, at 11:00 a.m., Gulf Standard Time, and will reconvene only virtually via live audio webcast on the Internet by visiting www.meetnow.global/MD59M9U.

We have engaged with the transfer agent and other relevant parties to seek reclassification of the Auditor Ratification Proposal and expect that the Auditor Ratification Proposal will be reclassified as routine prior to the reconvened Annual Meeting, which would permit brokers, banks, and other nominees to exercise discretionary voting authority for shares held in "street name."

During the period of the adjournment, the Company will continue to solicit proxies with respect to the proposals set forth in the Proxy Statement. Proxies previously submitted in respect of the Annual Meeting will be voted at the reconvened meeting unless properly revoked, and stockholders who have already submitted a proxy to vote their shares need not take any action.
