On behalf of the Board, I am pleased to offer you the opportunity to subscribe for fully paid ordinary shares under the SPP. The Company is offering eligible shareholders the opportunity to apply under the SPP for up to a maximum of A$30,000 worth of fully paid ordinary shares in the Company (New Shares). Shareholders will be eligible to participate in the SPP if they have a registered address in Australia, New Zealand or the United Kingdom as at 7.00pm (AEST) on Wednesday, 12 July 2023 (Eligible Shareholders). Residents of New Zealand and the United Kingdom will also need to comply with certain requirements set out in the SPP Offer Booklet. The exact pricing of the SPP is still to be determined, and will be set at the lower of: $0.036 per New Share, being the price paid under the Placement; and 2.5% discount to the VWAP of shares traded on the ASX during the five trading days up to the closing date of the SPP (5 Day VWAP), rounded to the nearest half cent, (the 'SPP Issue Price'). • • As the 5 Day VWAP will not be known until the Closing Date, the SPP Issue Price cannot be determined until the close of the SPP Offer. The Company has applied to ASX for a waiver of Listing Rule 7.1, to permit the Company to issue New Shares under the SPP to be conducted in accordance with the ASIC Instrument, without shareholder approval, with the pricing to be determined as set out above, and on the condition that the number of New Shares issued under the SPP is not greater than 30% of the number of fully paid ordinary shares already on issue (ASX Waiver). In the event that the ASX Waiver is not granted, the Company intends to seek Shareholder approval to issue the New Shares under the SPP, with such issue to be conditional on receipt of this shareholder approval. SPP Offer Booklet An offer document with the terms and conditions for the SPP offer was lodged with the ASX today (SPP Offer Booklet). A copy of the SPP Offer Booklet which contains information about how to apply under the Offer is available online at https://events.miraqle.com/at1-offer and on the Company's ASX Market Announcements Platform at https://www2.asx.com.au/markets/company/at1.

The offer of New Shares under the SPP is made in accordance with ASIC Corporations (Share and Interest Purchase Plans) Instrument 2019/547 (ASIC Instrument).
