Notes:

1.

Due to the cross-border implementation of the settlement of the Scheme Consideration Shares, the ASPI Common Stock to be issued to Scheme Participants recorded in the South African Register under the Scheme will be issued on the ASPI US share register on the Scheme Consideration Record Date plus 1 (one) Business Day (Monday, 5 January 2026at approximately 9:00 NY/ET which is 15:00 SAST) and delivered to Computershare US custody account, which will then only allow the Consideration Shares to be settled to Scheme Participants in South Africa by Strate on the Scheme Consideration Record Date plus 2 (two) Business Days (Tuesday, 6 January 2026). As trades in ASPI Common Stock on the JSE is settled in the electronic settlement system used by Strate, settlement of trades takes place 3 (three) Business Days after the date of such trades, the trading in the entitlements to the ASPI Common Stock (which will be delivered to Scheme Participants recorded in the South African Register) will accordingly only commence on the Scheme JSE LDT plus 2 (two) Business Days (Wednesday, 31 December 2025) despite the listing of such ASPI Common Stock taking place on Scheme JSE LDT plus 1 (one) Business Day (Tuesday, 30 December 2025).

2.

As previously set out in the Circular, the cash value of fractional entitlements pursuant to the Scheme will be calculated and announced on the Scheme JSE LDT plus 2 (two) Business Days, which deviation from the JSE corporate action timetable was necessitated by the cross-border implementation of the Scheme.
