This Ruling applies from 1 July 2025 to 30 June 2026. CGT event A1 happened on the disposal of your Robex Resources Inc. shares and CHESS Depository Interests 7. CGT event A1 happened on the Effective Date when you disposed of each of your Robex Shares (section 104-10 and paragraph 104-10(3)(b)). 8. The capital proceeds from CGT event A1 happening to each Robex Share is the market value of the 7.862 ordinary shares in PDI you received in respect of your disposal of each Robex Share (subsection 116-20(1)). The market value of the PDI shares is worked out at the time of CGT event A1 happening. 9. You made a capital gain from CGT event A1 happening if the capital proceeds from the disposal of your Robex Share exceeded the cost base of that share (subsection 104-10(4)). 10. You made a capital loss from CGT event A1 happening if the capital proceeds from the disposal of your Robex Share were less than the reduced cost base of that share (subsection 104-10(4)). Availability of scrip for scrip roll-over for your Robex Resources Inc. shares and CHESS Depository Interests 11. Subject to the qualification in paragraph 12 of this Ruling, if you made a capital gain from the disposal of a Robex Share, you may choose to obtain scrip for scrip roll-over for the capital gain (sections 124-780 and 124-785). 12. Scrip for scrip roll-over cannot be chosen if any capital gain you might make from your PDI shares would be disregarded, except because of a roll-over (paragraph 124-795(2)(a)). Foreign resident holders of Robex Resources Inc. shares and CHESS Depository Interests 13. If you were a foreign resident just before the Effective Date, you disregard a capital gain or capital loss made from the disposal of your Robex Share, as your Robex Share was not taxable Australian property pursuant to table items 1, 2 and 4 of section 855-15. Consequences if you choose scrip for scrip roll-over for your Robex Resources Inc. shares and CHESS Depository Interests Capital gain is disregarded 14. If you choose scrip for scrip roll-over, you disregard the capital gain you made from CGT event A1 happening on the disposal of your Robex Share (subsection 124-785(1)). Cost base and reduced cost base of shares in Predictive Discovery Limited 15. If you choose scrip for scrip roll-over, the first element of the cost base and reduced cost base of a replacement PDI share you received is worked out by reasonably attributing to it the cost base and reduced cost base (respectively) of the Robex Share for which it was exchanged and for which you obtained the roll-over (subsections 124-785(2) and (4)). 16. If all of your Robex Shares were acquired on the same date and they have identical rights and obligations, then we accept that a reasonable method of attribution would be to calculate the first element of the cost base and reduced cost base (respectively) of each replacement PDI share by dividing the total cost bases and total reduced cost bases (respectively) of your Robex Shares by the number of replacement PDI shares you received. Acquisition date of shares in Predictive Discovery Limited 17. If you choose scrip for scrip roll-over, for the purposes of working out whether a future capital gain from the replacement PDI share is a discount capital gain, the PDI share acquired in exchange for your Robex Share is taken to have been acquired on the date you acquired (for capital gains tax purposes) the corresponding Robex Share involved in the roll-over (table item 2 of subsection 115-30(1)). Consequences if you do not choose, or cannot choose, scrip for scrip roll-over 18. If you do not choose, or cannot choose, scrip for scrip roll-over, you must take into account any capital gain or capital loss from CGT event A1 happening on the disposal of your Robex Share in working out your net capital gain or net capital loss for the income year in which CGT event A1 happened (sections 102-5 and 102-10). 19. If you made a capital gain from CGT event A1 happening on the disposal of your Robex Shares, and scrip for scrip roll-over is not chosen or cannot be chosen, you can treat the capital gain as a discount capital gain provided that the conditions of Subdivision 115-A are met. In particular, the Robex Shares you disposed of must have been acquired at least 12 months before the Effective Date (section 115-25). Cost base and reduced cost base of shares in Predictive Discovery Limited 20. If you do not choose, or cannot choose, scrip for scrip roll-over, the first element of the cost base and reduced cost base of a replacement PDI share you received is equal to the market value of the Robex Share you gave in respect of acquiring the PDI share (subsections 110-25(2) and 110-55(2)). 21. The market value of the Robex Shares exchanged is worked out at the time when you acquired the PDI shares on the Effective Date. 22. We accept that you can apportion the total market value of your Robex Shares (worked out as at the Effective Date) across the total number of PDI shares you acquired on the Effective Date (subsection 112-30(1)). Acquisition date of shares in Predictive Discovery Limited 23. If you do not choose, or cannot choose, scrip for scrip roll-over, the acquisition date of the new PDI shares is the date on which those shares were issued to you, being the Effective Date (table item 2 of section 109-10). 24.
