Dear Sir / Madam,

Final Issue of Shares to Devico KMPs

IMDEX Limited (“IMDEX”) advises that on 2 June 2026 it issued a final tranche of 1,095,232 fully paid ordinary shares to certain key management personnel (“KMP”) of Devico AS in accordance with reinvestment arrangements established under the Share Purchase Agreement (“SPA”) between IMDEX and Devico AS.

As disclosed in IMDEX’s announcement dated 19 January 2023 and the accompanying Investor Presentation (refer slide 7), certain Devico KMPs entered into commitments as part of the transaction under which they agreed to reinvest approximately 30% of their exit proceeds into newly issued IMDEX shares. This final tranche was also foreshadowed in the ASX notification published on 5 March 2026.

Under the reinvestment agreements, additional KMP reinvestment shares were subject to time-based and performance-based vesting conditions. Following completion of the relevant performance period and final assessment of the applicable criteria, the relevant awards vested and the associated shares have been issued.

The shares were acquired by IMDEX on market and allocated in accordance with the Devico transaction arrangements.

This final tranche is the last payment obligation to KMP arising under the Devico SPA with no further shares payable to under any reinvestment agreements.

Yours faithfully
Imdex Limited

Michael Tomasz
Company Secretary

This announcement has been approved for lodgement by the IMDEX Company Secretary
