ASX ANNOUNCEMENT

7 July 2025

Appendix 3Y’s: Change of Directors’ Interest Notice

Mindax Limited (ASX: MDX or the Company) is pleased to confirm that, following approval of shareholders at the EGM held on 3 July 2025, each of the Company’s directors have been issued with the options as outlined in the Notice of Meeting dated 23 May 2025.

An Appendix 3Y is attached for each director.

The Company also advises that, during the preparation of the notices and reconciling with internal records, share transactions involving Mr Qinglong Zeng’s indirect holding through the Zeng Superannuation Fund A/C were identified as not having been notified to ASX, and as a result, the notification of this trade falls outside the timeframes required under the ASX Listing Rules. The transactions occurred on 17 April 2025.

Regarding Mr Zeng’s previous trade, the Company states:

• (a) The Appendix 3Y was lodged late due to an oversight. Once the oversight was identified, the document was promptly lodged with the ASX.

• (b) The Company and its Directors are aware of their obligations under the ASX Listing Rules, especially those outlined in Listing Rules 3.19A and 3.19B. The Company will provide additional training to enhance understanding of these obligations. Furthermore, the Company has arrangements with the Directors as required by Listing Rule 3.19B.

• (c) The Company views the late lodgement as an isolated incident and, to promote best practice, is reviewing its processes and procedures. This review includes a commitment to discuss the Company’s obligations under Listing Rule 3.19A with the Directors, as well as the arrangements under Listing Rule 3.19B and the Securities Trading Policy for timely disclosure by the Directors to the Company.

The Appendix 3Ys follow.

This announcement has been authorised for release by Dennis Wilkins, Company Secretary.
