1. Purpose of this Further Supplementary Prospectus

As announced on 8 September 2021, the Company has been served with an application for an interim injunction in the High Court of the Hong Kong Special Administrative Region.

The proceedings have been brought by a securityholder of the Company, who holds approximately 15,000 CDIs in Astron ( Plaintiff ). The Plaintiff is seeking:

• (a) a permanent injunction to restrain the Defendant (Astron) from taking any steps, whether directly or indirectly, to carry out, proceed with, implement and/or perform any other acts in respect of Resolution 1 of the Company’s Notice of Meeting dated 2 July 2021, which was approved by the securityholders of Astron at the Meeting on 19 July 2021 (see ASX announcements 2 July 2021 (Notice of Meeting), 19 July 2021 (Results of Meeting), 21 July 2021 (First Supplementary Prospectus), 17 August 2021 (Appendix 3A.5) 18 August 2019 (Second Supplementary Prospectus)) ( Permanent Injunction ); and

• (b) an interim injunction on the same terms pending the resolution of the Permanent Injunction ( Interim Injunction ).

The Plaintiff is also seeking a declaration that the proposed declaration of, and distribution in-specie of, a dividend under Resolution 1 of the Notice of Meeting is unlawful.

The Interim Injunction as scheduled was heard on Friday 10 September 2021 in Hong Kong. The Plaintiff was successful and the Interim Injunction was granted.

The hearing in respect of the Permanent Injunction has been set down to be heard in the High Court of the Hong Kong Special Administrative Region on 21 December 2021.

This Further Supplementary Prospectus has been prepared by the Company to update the market regarding the application. The Company has appointed legal advisers in Hong Kong to assist with opposing the Permanent Injunction.

The in-specie distribution was due to be carried out by no later than 13 September 2021. Astron has accordingly been required by the grant of the Interim Injunction to extend the timetable.

This Further Supplementary Prospectus also updates the Timetable of the Offer, so that the Distribution will complete no later than 5pm on 24 December 2021 (AEST), subject to any further extension as required by the Company or the ASX.
