Receipt of Invalid Member Notice Under 249D of the Corporations Act

4DS Memory Limited (“4DS” or “the Company”) advises that on 18 November 2025 it received:

  1. A Notice of Intention to Move a Resolution to Remove a Director under section 203D(2) of the Corporations Act 2001 (Cth) (“Corporations Act”) dated 12 November 2025; and

  2. A Request That Directors Call a General Meeting under section 249D of the Corporations Act dated 12 November 2025.

The Notices were submitted by three shareholders, FYNAA Pty Ltd, Sue Balagiannis and Damen Diamantopoulos (together, the “Requisitioning Members”), who collectively hold more than 5% of the votes that may be cast at a general meeting.

The Section 249D request was not provided in accordance with the Corporations Act and is invalid.

Content of Notices

The notice gives notice of the Requisitioning Members’ intention to requisition a general meeting of the Company and put forward resolutions to remove Mr David McAuliffe as a director of the Company.

The Requisitioning Members have given notice pursuant to the notice given under Section 203D of the Corporations Act and requested pursuant to the notice given under Section 249D of the Corporations Act, that shareholders consider the following resolutions at a general meeting to be convened:

  1. Resolution to remove Mr David McAuliffe as a director of the Company pursuant to section 203D(1) of the Corporations Act.

  2. Resolution to remove any director appointed after the date of the Notices and before the commencement of the meeting, other than directors elected or re-elected at the Annual General Meeting held on 20 November 2025.

The Company has notified the legal representative of the Requisitioning Shareholder to inform them of that fact and that, failing receipt by the Company of valid notices under Section 249D, the Board is not required to take any action to convene the general meeting sought.

The Company will keep shareholders updated on any material developments.
