Dear Manager,

APPENDIX 3Y – LATE LODGEMENT NOTICE

Please find attached an Appendix 3Y “Change of Director’s Interest Notice” for Mr Jonathan

Rubinsztein relating to shares in Nuix Limited acquired by Mr Rubinsztein on 26 August 2025.

In relation to the late lodgement of the attached Appendix 3Y, we advise as follows:

1. The Appendix 3Y is being lodged late due to an administrative oversight. As soon as the oversight was identified, the documents were prepared and lodged with ASX.

2. The acquisition arose from vesting of performance rights which was disclosed to the market in an Appendix 3G dated 29 August 2025. The Appendix 3G detailed the number of performance rights vesting, and the number ordinary shares thereby acquired by Mr Rubinsztein.

3. Nuix Limited and the directors are aware of their obligations under ASX Listing Rules 3.19A and 3.19B.

4. Nuix Limited considers that the late lodgement is an isolated incident and believes that its current practices are adequate to ensure compliance with the ASX Listing Rules.

Yours faithfully
