1This is an onerous supply contract provision relating to the raw material used in the Sandouville nickel refinery's production process, which is purchased under a single supply contract previously maturing on 31 December 2027. Due to sustained losses incurred at the operation, the Group assessed whether the supply contract is onerous at 31 December 2023. Consequently, the Group determined whether the unavoidable costs of meeting the obligations under the contract exceed the economic benefits expected to be received under it. The unavoidable costs under a contract reflect the least net cost of exiting from the contract, which is the lower of the cost of fulfilling it and any compensation or penalties arising from failure to fulfil it. Based on this assessment, the Group recognised an onerous contract provision amounting to R1,865 million, which represents the present value at 31 December 2023 of the penalty payable on early exiting the supply contract and the unavoidable losses to be incurred in meeting Sandouville's obligations under the contract during the notice period. Before the separate provision for the onerous contract was established, the Group recognised an impairment loss on assets, partially dedicated to the contract (see note 10). The onerous contract provision was calculated based on an expectation of terminating the contract in line with the required notice period and discounted at a pre-tax rate of 5.75%, reflecting the risks specific to the provision. During 2024, the Group agreed with the supplier to terminate this supply contract with final delivery made in January 2025. During 2024, additional provisions were raised for onerous contracts amounting to R200 million in respect of the Sandouville nickel refinery's production process 2The provision, included in Sandouville segment, decreased due to the realisation of onerous contract losses provided for at 31 December 2023 3A payment made for R45 million (2024: R665 million) was in respect of a penalty resulting from early exiting the supply contract. The remaining payment was in respect of the legal settlement with Appian 4Included in the 2024 balance is the onerous contract provision relating to the raw material used in the Sandouville nickel refinery's production amounting to R121 million and the balance relates to additional provisions raised for onerous contracts in respect of the Sandouville nickel refinery's production process 5The current portion at 31 December 2025, 31 December 2024 and 31 December 2023 relates to the onerous contract provisions

| Disclosure of sensitivity to key assumptions | The Group's environmental rehabilitation obligation is sensitive to changes in certain assumptions applied in the calculation of the balance of the obligation at 31 December 2025. The table below illustrates the impact of certain changes to the assumptions on the balance of the obligation at 31 December 2025, holding all other assumptions constant:
