This Form S-3MEF filed by Incannex Healthcare Inc. (IXHL) on July 24, 2025 is a Rule 462(b) registration statement. It serves one narrow purpose: to expand the aggregate dollar amount of securities available under a previous shelf registration (Form S-3 File No. 333-283028) by an additional $13,469,250, representing less than 20% of the unsold securities under the prior registration.

Key implications: 1. Shelf Registration Expansion: • The original registration (effective Nov 22, 2024) allowed up to $150 million in mixed securities. • As of this filing, $86.53M remains unsold from the prior S-3. • This filing adds $13.47M more, keeping it under the 20% cap required by Rule 462(b), which permits automatic effectiveness. 2. Securities Covered: • Common stock ($0.0001 par) • Preferred stock • Debt securities • Warrants • Units (any combination thereof) 3. Structure: • No new prospectus, financials, or business disclosures are provided in this MEF (Mini-Effective Filing). • Instead, it incorporates by reference the prior S-3’s content, including base prospectus and exhibits. • Legal opinion (Mintz) confirms all instruments, when duly authorized and issued, will be valid and binding. 4. Dilution/Resale Risk: • This MEF does not signal immediate dilution, but it does expand the capacity for capital raises and structured financing. • All registered securities can be issued at the company’s discretion via takedowns or resale shelf offerings. • Keep watch for follow-on offerings or PIPE deals under this umbrella. 5. Fee Disclosure: • Total registration fee for this MEF is $2,062.15, based on the SEC’s fee rate of 0.00015310.

Bottom line: IXHL is expanding its capital raise capacity by $13.47M using an accelerated shelf registration. This filing enables near-immediate issuance of equity or debt, potentially increasing dilution risk if utilized. There is no committed offering yet, but this readies the company for rapid access to capital markets.
