Update on Finsch Business Rescue Process

Further to the announcement made on 29 May 2026 in which we confirmed that Finsch Diamond Mine ("Finsch") had been placed into Business Rescue, and on 28 July 2026, where an update was provided on the progress to date, the Business Rescue Practitioners presented the proposed Business Plan ("the Plan") to the Finsch creditors on 07 August 2026 for voting. The Plan was adopted and therefore approved by the creditors with the relevant thresholds required to give the Business Rescue Practitioners the mandate to execute on the adopted Plan.

The salient points of the Plan that was approved by the creditors are as follows:

1. The Business Rescue Practitioners have not found a viable outcome to restart operations at Finsch.
2. The creditors have approved the Plan to sell off the assets of Finsch in order to recover the maximum amount of value possible for Finsch's creditors.
3. The secured creditor has provided some Post Commencement Funding ("PCF") to enable the continuation of limited activities on site and which includes the reclamation of assets.
4. Any monies recovered from the sale of assets under the approved Plan, will be distributed as per the ranking of claims, with the secured creditor's claims, including its PCF funding, ranking as the highest.
5. To support the sale of assets at Finsch, a skeleton labour structure for reclaiming of the assets for a defined period of time has been established, and they along with the remaining workforce at Finsch will be treated as per the provisions of S189 under the South African Labour Act, 66 of 1995. All employee claims under the S189 process will be treated as a claim against Finsch and will be paid out in accordance with the ranking of claims.

The Company will continue to update the market on material developments going forward.
