[ineligible shareholder]

Dear Shareholder,

Non-Renounceable rights issue – letter to ineligible shareholders

On 28 February 2025 Biotron Limited ( Company ) announced a renounceable pro rata offer of approximately 902 million fully paid ordinary shares ( New Shares ) at an issue price of $0.003 per New Share to raise up to approximately $2.7 million (before costs) ( Rights Issue ).

The Rights Issue is offered to holders of the Company’s fully paid shares held as at 7pm (AEDT) on 6 March 2025 ( Record Date ) with a registered address in Australia or New Zealand on the basis of 1 new fully paid ordinary share for every existing share held.

The Company has decided that it would be impractical to make offers under the Rights Issue to shareholders with a registered address outside Australia or New Zealand ( Ineligible Shareholders ), having regard to the number of such shareholders, their holdings and the compliance costs required to offer the Shares under the Rights Issue to those shareholders.

Unfortunately, since you are an Ineligible Shareholder, no offer is being made to you and the offer document prepared by the Company in relation to the Rights Issue will not be sent to you.

This letter is neither an offer to issue new shares to you, nor an invitation for you to apply for new shares, and you do not have to take any further action in relation to the Rights Issue.

Please contact the Company Secretary (02) 9300 3344 if you have any queries.

Yours faithfully

Peter J. Nightingale Company Secretary
