Merger Implementation Timetable

Predictive Discovery Limited (ASX: PDI) ("PDI") and Robex Resources Inc. (ASX: RXR, TSX-V: RBX) ("Robex") are pleased to advise the detailed implementation timetable for the merger between the companies (the "Transaction").

The Transaction is being implemented by way of a statutory plan of arrangement in the Province of Québec, Canada under the Business Corporations Act (Québec) ("Arrangement"), pursuant to the arrangement agreement dated 5 October 2025 (as amended).

As announced on 8 April 2026, all conditions precedent have been satisfied or waived (as applicable), and the Transaction is unconditional and proceeding to completion and implementation ("Implementation"), with the effective date scheduled to occur on 15 April 2026 ("Effective Date").

Pursuant to the Implementation of the Transaction, Robex shareholders and CDI holders will exchange their Robex shares or CDIs, as applicable, for newly issued PDI ordinary shares on the date of Implementation, in accordance with the terms of the Arrangement.

Each Robex share and each Robex CDI will be exchanged for 7.862 PDI shares (the "Exchange Ratio"), with fractions rounded down to the nearest whole PDI share.

Upon Implementation:

• Robex shareholders and CDI holders will cease to hold Robex shares and CDIs;
• Robex shareholders and CDI holders will be issued PDI shares through the relevant PDI Canadian or Australian share registers, as applicable; and
• outstanding Robex securities that are exercisable or exchangeable for Robex shares will remain outstanding in accordance with their terms, but will be exercisable or exchangeable for a number of PDI shares and at an exercise price (as applicable) that is appropriately adjusted based on the Exchange Ratio.
  

Robex CDI holders do not need to take any action to receive their PDI shares. Registered Robex shareholders will need to submit a Letter of Transmittal, along with the share certificate or direct registration system advice representing their Robex shares, to the depositary for the Arrangement, Computershare Investor Services Inc. ("Depositary"), at the address specified in the Letter of Transmittal to receive their PDI shares. A Letter of Transmittal was mailed to all registered Robex shareholders as required and is available under Robex's SEDAR+ profile at sedarplus.ca. Non-registered Robex shareholders should contact their intermediary for questions on how to receive their PDI shares. Holding statements will be dispatched following Implementation in accordance with the indicative timetable set out below.

Following Implementation:

• Robex shares are planned to be delisted from the TSX Venture Exchange ("TSX-V");
• Robex CDIs are planned to be removed from quotation on the Australian Securities Exchange ("ASX"); and
• PDI will continue to trade on the ASX (under the ticker code "PDI"), with trading on the Toronto Stock Exchange ("TSX") expected to commence shortly after Implementation (under the ticker symbol "PDI").
  

The indicative timetable for Implementation of the Transaction is set out below.

TAXATION: SCRIP-FOR-SCRIP CGT ROLL-OVER RELIEF

Robex has sought a class ruling from the Commissioner of Taxation on the availability of scrip-for-scrip CGT roll-over relief for Australian resident shareholders. The Commissioner will not issue a class ruling until after completion of the Transaction and any class ruling obtained will be available via PDI's disclosures on ASX once issued by the Commissioner.

If roll-over relief is confirmed as being available, eligible Robex shareholders may choose to apply roll-over relief in respect of the exchange of their Robex shares or CDIs for PDI shares. The choice is made by the shareholder when preparing their Australian income tax return for the income year in which the Transaction is implemented. Shareholders are recommended to seek independent tax advice.

This joint ASX Announcement has been authorised for release by the PDI Board and the Robex Board.

Neither the TSX-V nor its Regulation Services Provider (as that term is defined in the policies of the TSX-V) accepts responsibility for the adequacy or accuracy of this release.
