Financial performance Headline earnings Headline earnings for F2023 decreased by 21% to R8 981 million or R45.81 per share (F2022: R11 338 million or R57.87 per share). The F2022 headline earnings included re-measurement losses of R808 million mainly related to the ARM Coal Loans owing to Glencore Operations South Africa. These loans have since been fully settled. The average realised rand weakened by 17% versus the US dollar to R17.76/US$ compared to R15.21/US$ in F2022. For reporting purposes, the closing exchange rate was R18.90/US$ (30 June 2022: R16.38/US$). ARM Ferrous headline earnings were 17% lower at R5 528 million (F2022: R6 682 million), driven by a 34% decrease in headline earnings in the manganese division and an 11% decrease in the iron ore division. Lower headline earnings in the iron ore division were driven by a decrease in the average realised US dollar iron ore prices and lower export sales volumes, partially offset by the weaker rand versus US dollar exchange rate and lower freight costs. Iron ore headline earnings include a R279 million (pre-tax) negative fair value adjustment on iron ore sales (F2022: R618 million negative adjustment), of which 66% is based on confirmed prices and 34% is based on forward prices. Refer to page 8 for further information on the mark-to-market adjustments in ARM Ferrous. Lower headline earnings in the manganese division were driven by a decrease in the average realised US dollar manganese ore and alloy prices and higher production and railage costs, which were partially offset by the weaker rand versus US dollar exchange rate and lower freight costs. 3 ARM Platinum headline earnings decreased by 52% to R1 465 million (F2022: R3 066 million). Two Rivers Mine headline earnings reduced to R1 262 million (F2022: R1 968 million), mainly due to negative mark-to-market adjustments of R1 065 million (F2022: R709 million negative adjustment) and a 24% increase in unit cash costs (on a rand per 6E PGM ounce basis) which is as result of above inflationary pressures on costs. Challenges with grade persisted at the mine, the head grade reduced to 3.00g/t compared to 3.22g/t last year. Modikwa Mine reported a 36% decline in headline earnings to R819 million (F2022: R1 270 million), which included negative mark-to- market adjustments of R253 million (F2022: R231 million). The mine’s production volumes decreased by 3% while unit cash costs (on a rand per 6E PGM ounce basis) were up by 21% due to above inflationary pressures on costs. For more detail and a table showing the mark-to-market adjustments at Two Rivers and Modikwa mines, refer to page 14 of the full announcement. Bokoni Mine, which is included for the first time in the ARM annual results, reported a headline loss of R406 million for F2023. The early ounce project, approved in March 2023, is on track and the first PGM ounce production is expected in the second quarter of F2024. Nkomati Mine reported a headline loss of R210 million (F2022: R172 million). The mine was placed on care and maintenance on 15 March 2021. ARM and its joint venture partner are considering various options for the future of Nkomati Mine. ARM Coal reported headline earnings of R1 535 million (F2022: R928 million) driven mainly by a reduction in re-measurement losses of R1 252 million which resulted from accelerated repayment of the loans owing to shareholders. GGV Mine’s headline earnings were R540 million (F2022: R5 million loss). PCB headline earnings were R995 million (F2022: R933 million). Refer to pages 18 and 19 of the full announcement for a detailed analysis of the GGV and PCB operational profit performance. No re- measurement losses were included in PCB headline earnings. 4 ARM Corporate and other (including Gold) reported headline earnings of R649 million (F2022: R826 million). Included in ARM Corporate and other are re-measurement gains of R12 million (F2022: R448 million). Machadodorp Works headline loss of R196 million (F2022: R164 million) related to research into developing energy-efficient smelting technology. Basic earnings and impairments Basic earnings of R8 078 million (F2022: R12 426 million) included attributable impairments as follows: - An impairment of property, plant and equipment at Beeshoek Mine of R773 million after tax - An impairment of property, plant and equipment at Cato Ridge Works of R38 million after tax - An impairment of the Assmang investment in Sakura of R150 million after tax. Refer to note 4 of the condensed group financial statements in the full announcement for further details. Financial position and cash flow At 30 June 2023, ARM had net cash of R9 779 million (30 June 2022: R11 175 million), a decrease of R1 396 million compared to the end of the 2022 financial year. This amount excludes attributable cash and cash equivalents held at ARM Ferrous (50% of Assmang) of R4 939 million (30 June 2022: R5 342 million). Cash generated from operations decreased by R418 million to R8 090 million (F2022: R8 508 million) after an inflow in working capital of R1 212 million (F2022: R1 640 million outflow), which was mainly due to an inflow in trade receivables. In F2023, ARM paid R6 666 million in dividends to its shareholders, representing the interim dividend of R14.00 and the final dividend of R20.00 per share declared for F2022 (F2022: R6 270 million representing the interim dividend of R12.00 and the F2021 final dividend of R20.00 per share). Net cash outflow from investing activities was R7 511 million (F2022: R2 492 million) and included the net cash payment for the acquisition of Bokoni Mine of R3 441 million (which represents the gross cash payment of R3 500 million, net of R59 million cash acquired in the transaction). 5 Borrowings of R251 million (F2022: R109 million) were repaid during the period, resulting in gross debt of R242 million at 30 June 2023 (30 June 2022: R484 million). The group net asset value per share increased by 7% to R219.04 per share (30 June 2022: R205.45 per share). Investing in growth and the existing business ARM continues to be confident about the long-term profitability of Bokoni. Good progress has been made in advancing the DFS, which has been based on a phased development approach to reduce peak funding requirements, optimise production ramp-up and minimise project execution risk. The DFS also preserves the optionality to increase production to an optimal production rate in the future. The DFS indicates higher capital costs relative to the 2021 investment case due to inflationary cost increases and an enhanced scope definition. The project remains robust and is expected to be attractive in terms of industry cost competitiveness. The DFS will now advance to bankable feasibility and then be presented to the board for approval. The early ounce project that was approved in March 2023 is progressing well, with the first saleable PGM concentrate expected by December 2023. The early ounce project focuses on a combination of mining high-grade UG2 stopes in the Middelpunt Hill shaft and early on-reef development of the new UG2 mine. Critical orders for long lead items, to de-risk the project schedule, have been placed. The early ounces will enable the mine to commence with early development of the underground infrastructure required for the new planned UG2 mine. We continued to invest in our existing operations with segmental capital expenditure of R7 201 million for the period (F2022: R4 727 million). The increase in capital expenditure was mainly due to the Merensky Project at Two Rivers Mine. Capital expenditure for the divisions is shown on page 7 of the full announcement and discussed in each division’s operational performance section from page 8 of the full announcement.
