**INFORMATION CONTAINED IN THIS FORM 6-K REPORT** 

As previously disclosed, Kazia Therapeutics Limited (the "Company") received a notice (the "Notice") from the Listing Qualifications department (the "Staff") of The Nasdaq Stock Market LLC ("Nasdaq") on May 12, 2025 notifying the Company that from March 28, 2025 to May 9, 2025, the Company's Market Value of Listed Securities ("MVLS") was below the minimum of $35 million required for continued listing on The Nasdaq Capital Market pursuant to Nasdaq Listing Rule 5550(b)(2) (the "MVLS Requirement"). In accordance with Nasdaq Listing Rule 5810(c)(3)(C), Nasdaq provided the Company with 180 calendar days, or until November 10, 2025 (the "Compliance Date"), to regain compliance with the MVLS Requirement.

On November 12, 2025, the Company received a staff determination letter ("Staff Letter") from the Staff of Nasdaq indicating that the Company had not regained compliance with the MVLS Requirement by November 10, 2025. Pursuant to the Nasdaq Listing Rules and the Staff Letter, unless the Company timely requests a hearing before a Hearings Panel (the "Panel"), the Company's securities would be subject to suspension/delisting. Accordingly, the Company intends to timely request a hearing before the Panel. The hearing request will automatically stay any suspension or delisting action pending the hearing and the expiration of any additional extension period granted by the Panel following the hearing.

At the hearing, the Company intends to demonstrate its ability to regain compliance with the deficiencies cited by the Staff, as well as its ability to sustain long-term compliance with all applicable maintenance criteria. There can be no assurance that the Company's plan to regain compliance presented at the hearing will be accepted by the Panel, or that, if it is, the Company will be able to regain compliance with the applicable Nasdaq listing requirements.

The Company hereby incorporates by reference the information contained herein into the Company's registration statement on Form F-3 (File No. 333-281937).
