INFORMATION CONTAINED IN THIS FORM 6-K REPORT

On September 18, 2026, Kazia Therapeutics Limited (the “Company”) appointed JPMorgan Chase Bank, N.A. (“JPMorgan”) as the sole depositary for the Company’s American Depositary Receipt (“ADR”) program, replacing The Bank of New York Mellon (“BNY Mellon”). In connection with the appointment, the Company and JPMorgan entered into a Second Amended and Restated Deposit Agreement (the “Deposit Agreement”), pursuant to which JPMorgan will issue American Depositary Shares (“ADSs”), each representing five hundred (500) of the Company’s ordinary shares. The ADSs will continue to trade on The Nasdaq Capital Market under the symbol “KZIA.” JPMorgan has filed a Registration Statement on Form F-6 with the Securities and Exchange Commission in connection with the new ADR program. ADS holders do not need to take any action at this time. The transition is expected to be seamless, and existing ADS holders will continue to hold their positions without interruption.
