Appendix 3Y Change of Director’s Interest Notice

Attached is an Appendix 3Y - Change of Director’s Interest Notice in respect of changes in the relevant interests in securities held by Mr Michael Kavanagh, Chief Executive Officer & President.

On 16 January 2024, Mr Kavanagh acquired 44,054 Service Rights under the 2023 STI Award in accordance with the approval given by shareholders at the Company’s 2023 Annual General Meeting held on 3 November 2023. The delay in disclosing the issuance of the Service Rights to the ASX, as required by Listing Rule 3.19A.2, was an administrative oversight. To mitigate against this issue occurring in the future, the Company implemented a process change to ensure that a 3Y is lodged within the relevant timeframe. The Company considers that these arrangements are sufficient to ensure ongoing compliance with listing rule 3.19A.2.

Following this change, Mr Kavanagh continues to hold 1,364,496 shares. In addition, Mr Kavanagh holds 1,021,184 Rights and 286,885 Options, which are subject to various vesting conditions.

Authorised for release by Matthew Carbines, Secretary.
