1Refer to note 38 for further detail on restatement. (a)The R32.3 billion movement relates to mining assets acquired as part of the MAC Copper acquisition. Refer to note 13 for further details. (b)Refer to note 8 for the total loss on scrapping recognised. This relates primarily to the derecognition of mining assets that were no longer expected to provide future economic benefits. (c)Refer to note 24 for details on the adjustment to the rehabilitation asset. (d)During the 2026 year an amount of R1.2 billion (2025: R1.1 billion) was transferred to mining assets at Hidden Valley. This related to ongoing mining development costs. During the 2025 year the Doornkop 207 Level and Kareerand Tailings Storage Facility projects were completed and amounts of R643 million and R1.7 billion, respectively, were transferred to mining assets. (e)During the period, the group recognised a reversal of previously recognised impairment losses in respect of the Tshepong North, Tshepong South, Kusasalethu and Doornkop CGUs. Refer to note 5 for details. (f)Depreciation includes capitalised depreciation. Refer to note 5 for further detail on depreciation. The movement in the mining assets under construction is as follows:
1Relates to Tshepong North Sub 75 life of mine extension. Refer to note 5 for details. (a)The additions for 2026 mainly relates to:
1See discussion on developments on the project below. (b)Refer to note 10 for further detail on the capitalisation rate applied. (c)Relates to R2.9 billion undeveloped properties of the Eva Copper Project which were transferred to assets under construction following the approval of the final investment decision. The movement in the undeveloped properties is as follows:
Undeveloped properties comprise the Target North and Wafi-Golpu Project. For further details regarding the permitting process and other developments of the Wafi-Golpu Project, refer to note 20. The transfer of R2.9 billion relates to the Eva Copper Project undeveloped properties, which were transferred to assets under construction following the approval of the final investment decision. The carrying value of the undeveloped properties are as follows:

| Disclosure of Commodity Prices, Exchange Rates and Resource Value Assumptions | During the years under review, the group calculated the recoverable amounts (generally fair value less costs to sell) of CGUs for which indicators of impairment were identified (refer to note 5). These recoverable amounts are based on updated life-of-mine plans and the following relevant assumptions:

| Disclosure of Sensitivity Analysis - Impairment of Assets | Sensitivity analysis – impairment of assets Commodity prices – Gold One of the most significant assumptions that influence the LOM plans and therefore impairment and reversal assessments is the expected commodity prices. Management determined reasonably possible changes in gold price assumptions of a 5.5% decrease (2025: 10.8%) and 29.9% increase (2025: 29.1% ). These changes were based on determining reasonably possible adjusted long- term US$ gold price assumptions using the standard deviation of market analysts’ forecasted long-term US$ gold price assumptions. These reasonably possible adjusted long-term US$ gold price forecasts were then compared to Harmony's long-term US$ gold price assumption. These reasonable possible changes in assumptions would not change the conclusions reached regarding the recognition of impairments or reversal of impairments. The quantum of the reversals are also not affected. Commodity prices – Copper Management determined reasonably possible changes in copper price assumptions of an 11.2% decrease and an 11.4% increase. These changes were based on determining reasonably possible adjusted long-term US$ copper price assumptions using the standard deviation of market analysts’ forecasted long-term US$ copper price assumptions. These reasonably possible adjusted long-term US$ copper price forecasts were then compared to Harmony’s long-term US$ copper price assumption. The increase in the copper price assumptions would have resulted in no impairments being recorded. An 11.2% decrease in the copper price assumptions (with all other variables held constant) would have resulted in a R4.4 billion post-tax impairment being recorded as at 30 June 2026 for CSA. Production profile In addition to the expected commodity prices in 2025, the production profiles of Target 1 and Tshepong South have also been assessed as sensitive assumptions that influence the LOM plans, and therefore the impairment assessments of these CGUs. For Target 1, the recoverable amount was determined as R4.2 billion as at 30 June 2025. Management determined that should the production profile of Target 1 decrease by 8.6% (with all other variables held constant), this would result in the recoverable amount being equal to the post-tax carrying amount of R2.1 billion as at 30 June 2025. For Tshepong South, the recoverable amount was determined as R3.3 billion as at 30 June 2025. Management determined that should the production profile of Tshepong South decrease by 5.3% (with all other variables held constant), this would result in the recoverable amount being equal to the post-tax carrying amount of R2.3 billion as at 30 June 2025. 14Property, plant and equipment continued Mining assets continued Critical accounting estimates and judgements – impairment of assets continued Production profile continued The production profiles of the other CGUs tested for impairment are not considered to be sensitive assumptions. This is based on the fact that a 15.0% decrease in these production profiles (with all other variables held constant) would not result in any impairments being recognised as at 30 June 2025. The production profiles of all CGUs are not considered to be sensitive assumptions as at 30 June 2026.
