Tax Calculator

The IMB Off-Market Share Buyback provides an opportunity for IMB Shareholders to sell their Shares to IMB.

The potential Australian tax consequences of Eligible Participants that sell Shares under the Buyback will depend on their individual circumstances.

The Indicative Tax Calculator is intended to provide indicative examples of the likely after tax proceeds of selling IMB Shares under the 2025/26 Buyback for Australian resident Eligible Participants.

The Indicative Tax Calculator is based on the terms of the Buyback (as outlined in the IMB Off-Market Buyback Booklet dated 27 August 2025) and current tax legislation and administrative practices as at 14 August 2025.

It is important that you read the IMB Off-Market Buyback Booklet dated 27 August 2025 carefully. The description of the tax consequence of participating in the Buyback is set out in Section 3 of the Booklet.

The indicative Tax Calculator is not intended to:

• be a substitute for the IMB Off-Market Buyback Booklet;
• be a substitute for legal, financial, taxation or other professional advice; or
• provide guidance or advice about whether IMB Shareholders should participate in the 2025/26 Buyback.

It should not be relied upon for these purposes.

IMB makes no recommendation and is not giving any advice as to whether Eligible Participants should participate in the Buyback.

• you will not rely on the calculations in deciding whether to participate in the Buyback;
• IMB takes no responsibility as to the accuracy of the outcomes in the indicative examples or for any unauthorised changes to, or use of, the Indicative Tax Calculator.
