MARCH 2026 QUARTERLY ACTIVITY REPORT AND APPENDIX 4C

4DS Memory Limited (ASX:4DS) ("4DS" or "the Company") is pleased to provide its Quarterly Activities Report and Appendix 4C for the quarter ended 31 March 2026. This report should be read in conjunction with the Company's previous announcements, including the December 2025 Quarterly Report, and provides an update on ongoing strategic initiatives.

Corporate Activities

As announced on 27 April 2026, 4DS is progressing a proposed material acquisition and associated capital raising, which is expected to require the Company to re-comply with Chapters 1 and 2 of the Listing Rules. The Company remains in discussions with the ASX in relation to this process and will provide further details once these discussions are concluded.

The Company maintained its disciplined approach to cost management during the quarter, following the remuneration reductions implemented effective 1 November 2025.

These measures remain in place and continue to materially reduce the Company's cash outflows, preserving capital as the Company progresses toward execution of the above strategic initiative. In conjunction with the Company's proposed material acquisition, the Company is progressing the development and commercialisation of its PCMO ReRAM technology. The Company's validated 60nm PCMO ReRAM platform will remain the foundation of the Company's technology and development program. This pathway seeks to capitalise on the well-documented likely worldwide shortage of memory chips (including at the 60nm node).

As part of its strategy, Executive Chairman David McAuliffe is planning a trip to Asia in mid-May 2026 to undertake business development discussions and explore potential commercialisation opportunities in relation to 4DS's 60nm Interface Switching ReRAM technology. The Company will keep investors updated on any progress from such activities.

Announcements during the Quarter

During the quarter, the Company released its December 2025 Quarterly Activity Report and Appendix 4C on 29 January 2026, responded to an ASX price query on 19 February 2026, and released its Appendix 4D & Half-Year Financial Statements on 27 February 2026. Copies of these announcements are available in the Investor Centre section of the Company's website.

Financial Review

As at 31 March 2026, the Company held cash of $8.47 million, compared to $8.8 million at 31 December 2025. Net cash of $229k was used in operating activities during the March quarter, compared to $308k in the December quarter.

No material changes or events have occurred subsequent to 31 March 2026 that would materially affect the Company's financial position or disclosed activities.
