Redomicile Update – Sanctioning of Scheme

Astron Corporation Limited (ASX:ATR) ( Astron or the Company ) refers to the shareholder approved scheme of arrangement ( Scheme ) to redomicile the Astron Group[1] from Hong Kong to Australia ( Redomicile ) wherein the newly established Australian company, Astron Limited (referred to herein as Aus NewCo) will become the listed parent company of the Astron Group and the Company’s securities will be replaced with Aus NewCo securities on a two for one (2:1) basis.

The Company is pleased to announce that today the Court of First Instance of the High Court of Hong Kong ( Hong Kong Court ) has sanctioned the Scheme and the Company has filed a copy of the Hong Kong Court order with the Registrar of Companies in Hong Kong.

the Scheme Document released to the ASX on 2 July 2025[2] ):

1. Effective Date (20 August 2025) – (i) the date on which a copy of the order of the Hong Kong Court sanctioning the Scheme is expected to be registered with the Registrar of Companies in Hong Kong pursuant to section 673(6) of the Companies Ordinance; (ii) the Company confirms to the ASX that the Scheme has become effective (prior to 1:00pm AEST); and (iii) the last Trading Day of the CHESS Depository Interests ( CDI ) of the Company on the ASX.

Cross-border repositioning of securities between the CDI Register and the Register of Members will cease at 4.00pm local time in Melbourne and Hong Kong on the Effective Date. As such, should securityholders wish to transmute (i.e. convert) their CDIs to shares in the Company (or vice versa, as the case may be), they must do so before this deadline. Please note that transmutation of the Company’s securities will have no impact on the implementation of the Redomicile or the rights of securityholders under the Scheme.

1. First Trading Day after the Effective Date (21 August 2025) – to ensure seamless trading of Astron CDIs and Aus NewCo Shares, Aus NewCo Shares to be issued on the Implementation Date (29 August 2025) will be quoted on the ASX on a deferred settlement basis. For the avoidance of doubt, the quoted shares of Aus NewCo have not, at the time of quotation, been issued to securityholders and therefore any trading will be at the securityholder’s own risk.

2. Scheme Record Date (5:00pm (HKT) / 7:00pm (AEST) on 22 August 2025) – the record date of the Scheme for determination of the entitlements of the Scheme Shareholders and Scheme CDI Holders (as the case may be, other than Excluded Securityholders) to receive Aus NewCo Shares pursuant to the Scheme; and

3. Implementation Date (29 August 2025) – the date on which the Scheme will be implemented, where Aus NewCo Shares will be issued to the Scheme Shareholders (other than CHESS Depositary Nominees Pty Ltd) and Scheme CDI Holders, in consideration of the Scheme Shares being transferred to Aus NewCo which will become the holding company of the Astron Group.

1 ‘Astron Group’ means the Company together with its controlled subsidiaries. 2 See ATR ASX announcement titled ‘Notice of Court Meeting and Despatch of Scheme Document’.
