Transfer of CDIs by major holder

Astron Corporation Limited (ASX: ATR) (Astron or Company) refers to the attached Appendix 3Y, in relation to the transfer of CDIs by Kobe Investments Ltd. Kobe Investments Ltd is a company associated with the Managing Director, Mr Tiger Brown.

While the Appendix 3Y records the transfer of CDIs, given that there has been a change in the number of CDIs held by Kobe investments Ltd, there is no change to Mr Brown’s relevant interest in those CDIs and, for this reason, there is no associated change of substantial shareholder notification.

The transfer of CDIs is to beneficiaries of the Estate of the late Alexander Gavin Brown, and those CDIs are to be held so that the beneficiaries have the benefit of the economic interests in those CDIs, including in relation to any dividends and capital events.

This transfer represents the settlement of all outstanding issues in connection to the Estate of the late Alexander Gavin Brown insofar as they relate to Mr Tiger Brown and his associated entities, including Kobe Investments Ltd.

This announcement has been authorised for lodgement to ASX by the Managing Director of Astron.
