This Ruling sets out the income tax consequences for holders of ordinary shares in Alumina Limited (Alumina) who disposed of those shares to AAC Investments Australia 2 Pty Ltd (AAC2), a wholly owned subsidiary of Alcoa Corporation (Alcoa), on 1 August 2024 (Implementation Date). 2. Details of this scheme are set out in paragraphs 27 to 34 of this Ruling. 3. All legislative references in this Ruling are to the Income Tax Assessment Act 1997, unless otherwise indicated. Who this Ruling applies to 4. This Ruling applies to you if you: Note: Division 230 will not apply to individuals unless they have made an election for it to apply. When this Ruling applies 5. This Ruling applies from 1 July 2024 to 30 June 2025. Disposal of your Alumina Limited shares 6. CGT event A1 happened when you disposed of each of your Alumina shares to AAC2 (section 104-10). 7. CGT event A1 happened on the Implementation Date (paragraph 104-10(3)(b)). Capital proceeds 8. The capital proceeds from CGT event A1 happening to each Alumina share is the market value of the New Alcoa CDI you received (subsection 116-20(1)). 9. The market value of the New Alcoa CDI is worked out at the time of CGT event A1 happening. We will accept a market value for each New Alcoa CDI at that time of $47.96. Capital gain or capital loss 10. You made a capital gain from CGT event A1 happening if the capital proceeds from the disposal of your Alumina share exceeded the cost base of that share (subsection 104-10(4)). The capital gain is the amount of the excess. 11. You made a capital loss from CGT event A1 happening if the capital proceeds from the disposal of your Alumina share was less than the reduced cost base of that share (subsection 104-10(4)). The capital loss is the difference. 12. If you made a capital gain on disposing of your Alumina shares, you can treat the capital gain as a 'discount capital gain' provided you acquired, or are taken to have acquired, your Alumina share on or before 31 July 2023 and the other conditions of Subdivision 115-A are met. Foreign-resident shareholders generally disregard a capital gain or capital loss 13. If you were a foreign resident or the trustee of a foreign trust (for CGT purposes, as defined in subsection 995-1(1)), that held Alumina shares on the Implementation Date and those Alumina shares were not taxable Australian property for the purposes of subsection 855-10(1), you disregard a capital gain or capital loss you made from CGT event A1 happening when you disposed of your Alumina shares (section 855-10). 14. Your Alumina shares were taxable Australian property if they were either: 15. Your Alumina shares were an 'indirect Australian real property interest' if they passed: Availability of scrip for scrip roll-over 16. Subject to the qualification in paragraphs 17 and 18 of the Ruling, if you made a capital gain from the disposal of your Alumina shares, you may choose to obtain scrip for scrip roll-over for that gain (sections 124-780 and 124-785). Scrip for scrip roll-over is not available if you made a capital loss. 17. Scrip for scrip roll-over cannot be chosen if any capital gain you might make from the replacement New Alcoa CDI would be disregarded, except because of a roll-over (paragraph 124-795(2)(a)). 18. If you were a foreign resident just before the Implementation Date, you cannot choose scrip for scrip roll-over unless your replacement New Alcoa CDI were taxable Australian property (as defined in section 855-15) just after the Implementation Date (subsection 124-795(1)). Consequences if scrip for scrip roll-over is chosen 19. 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 Alumina shares (subsection 124-785(1)). 20. If you choose scrip for scrip roll-over, the first element of the cost base and reduced cost base of a replacement New Alcoa CDI you received is worked out by reasonably attributing to it the cost base and reduced cost base (respectively) of the Alumina shares for which it was exchanged and for which the roll-over was obtained (subsections 124-785(2) and (4)). 21. For the purposes of determining whether a future capital gain from New Alcoa CDIs is a discount capital gain, the date of acquisition of the replacement New Alcoa CDIs is taken to be the date you acquired your original shares in Alumina (table item 2 of subsection 115-30(1)). Consequences if you do not choose scrip for scrip roll-over 22. If you do not, or cannot, choose scrip for scrip roll-over, you must account for any capital gain or capital loss from the disposal of your Alumina shares 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). 23. If you make a capital gain where roll-over is not chosen, you can treat the capital gain as a discount capital gain if the conditions in Subdivision 115-A are met. In particular, the Alumina shares you disposed of must have been acquired at least 12 months before the Implementation Date (section 115-25). 24. If you do not, or cannot, choose scrip for scrip roll-over, the first element of the cost base and reduced cost base of your replacement New Alcoa CDIs is equal to the market value of the Alumina shares you exchanged in respect of acquiring New Alcoa CDIs (subsections 110-25(2) and 110-55(2)). 25. The market value of your Alumina shares is worked out at the time you acquired the replacement New Alcoa CDIs, which is on the Implementation Date (paragraph 110-25(2)(b) and subsection 110-55(2)). We will accept a market value for each Alumina share at that time of $1.37. 26. If you do not, or cannot, choose scrip for scrip roll-over, you are taken to have acquired the New Alcoa CDIs on the Implementation Date (table item 2 of section 109-10 and paragraph 104-35(5)(c)). 27.

Alumina was the head company of the Alumina income tax consolidated group. 29. At the time the scheme was entered into, Alumina's only material investment and asset was a 40% ownership stake in Alcoa World Alumina and Chemicals, an unincorporated global joint venture with Alcoa, which consists of affiliated entities that own, operate or have an interest in bauxite mines and alumina refineries in Australia and other countries.

The scheme of arrangement was approved by Alumina shareholders at a shareholders' meeting on 18 July 2024 and the scheme became effective on 23 July 2024. 33. Under the SID, each Alumina shareholder who held their shares at the Scheme Record Date would be entitled to receive 0.02854 New Alcoa CDIs for each Alumina share held (Scheme Consideration). 34.
