ASX RELEASE

20 December 2021

4DS Successfully Completes Share Purchase Plan

• 4DS has completed the SPP following a successful $2.5m Placement on 3 December 2021

• Valid applications received for approximately $5.934m under the SPP

• SPP applications to be scaled back to $3.5m

• Total proceeds of $6.0m from the Placement and SPP will be used to progress the development of 4DS’ Interface Switching ReRAM technology in 2022

4DS Memory Limited (ASX:4DS) ( 4DS or the Company ) is pleased to announce that it has successfully completed its Share Purchase Plan (SPP) which closed, oversubscribed, on 14 December 2021. Based on strong support for the SPP the Company has resolved to accept $3.5m under the SPP.

In conjunction with the completion of the Placement, the Company announced an SPP to offer existing shareholders on the record date, the opportunity to subscribe for up to $30,000 worth of new shares at the same price as the Placement ($0.048 per share), without any brokerage or other costs.

At the closing of the SPP at 5pm WST on 14 October 2021, 4DS had received valid applications for approximately $5.934m and will now undertake a scale back on applications by 46.4643% to achieve the SPP target of $3.5m. As the minimum amount under the SPP was $2,000, those shareholders who applied for that amount will not be scaled back.

The Company expects the new shares under the SPP will be issued and holding statements dispatched on 20 December 2021 and trading of the new shares is expected to commence on 21 December 2021.

Refunds are expected to be paid by direct credit (for those shareholders who have provided the Company with their bank details) or cheque on or around 21 December 2021. No interest will be paid on refunds.

The $6m raised from the Placement and SPP, minus associated costs of the Placement and SPP, will now be utilised to progress development of 4DS’ Interface Switching ReRAM technology with imec, maintenance of intellectual property and general working capital.

The Board thanks shareholders for the highly encouraging level of participation in the SPP.
