1The Group reports adjusted earnings before interest, taxes, depreciation and amortisation (EBITDA) based on the formula included in the facility agreements for compliance with the debt covenant. Adjusted EBITDA may not be comparable to similarly titled measures of other companies. Adjusted EBITDA is not a measure of performance under IFRS Accounting Standards and should be considered in addition to and not as a substitute for any other measure of financial performance and liquidity. For a reconciliation of profit before royalties and tax to adjusted EBITDA, see note 11.1 of the consolidated interim financial statements

2The US PGM operations’ underground production is converted to metric tonnes and kilograms, and financial performance is translated to SA rand (rand). In addition to the US PGM operations’ underground production, the operation treats various recycling material which is excluded from the 2E PGM production, average basket price and All-in sustaining cost statistics shown. PGM recycling represents palladium, platinum and rhodium ounces fed to the furnace

3The Platinum Group Metals (PGM) production in the SA operations is principally platinum, palladium, rhodium and gold, referred to as 4E (3PGM+Au) and measured at the concentrator, and in the US underground operations is principally platinum and palladium, referred to as 2E (2PGM) and US PGM recycling is principally platinum, palladium and rhodium referred to as 3E (3PGM)

4See “Salient features and cost benchmarks - Six months ” for the definition of All-in sustaining cost (AISC). The SA PGM All-in sustaining cost excludes the production and costs associated with the purchase of concentrate (PoC) from third parties

5The acquisition of the Reldan Group of Companies (Reldan) was concluded on 15 March 2024. The six months ended 30 June 2024 only includes the results since acquisition

6The SA PGM production excludes the production associated with the PoC from third parties. For a reconciliation of the production and third party PoC, refer to the "Reconciliation of operating cost excluding third party PoC for Total SA PGM operations and Marikana - Six months"

7Payable Zinc production is the payable quantity of zinc metal produced after applying smelter content deductions

8Average equivalent zinc concentrate price is the total zinc sales revenue recognised at the price expected to be received excluding the fair value adjustments divided by the payable zinc metal sold

9Adjusted EBITDA and AISC are not measures of performance under IFRS Accounting Standards and should not be considered in isolation or as substitutes for measures of financial performance prepared in accordance with IFRS Accounting Standards. See "Non-IFRS measures" for more information on the Non-IFRS metrics presented by Sibanye-Stillwater

10The US PGM operations’ All-in sustaining cost for the six months ended 31 December 2024 and 30 June 2024 were adjusted to include the Section 45X (S45X) Advance Manufacturing Production Credits. During the six months ended 30 June 2025 the US PGM operations recognised R699 million (US$39 million) and R563 million (US$30 million) which related to mining costs for the six months ended 31 December 2024 and 30 June 2024, respectively

Sibanye-Stillwater Operating and financial results | Six months ended 30 June 2025 2

OVERVIEW OF THE RESULTS FOR THE SIX MONTHS ENDED 30 JUNE 2025

The Group operating and financial performance for H1 2025 was pleasing, with safe production and costs from the operations consistent, and largely in line with the intended outcomes of the operational restructuring undertaken from mid-2023.

Greater operational stability and good cost control at most Group operations, combined with leveraged exposure of the SA gold operations to the rand gold price has notably improved Group profitability for H1 2025.

The positive financial outcomes from solid operational management and decisive restructuring, were amplified by the incorporation of Section 45X credits in terms of the Inflation Reduction Act (IRA), following agreements reached with third party refiners of our PGMs. A total S45X credit of R5.1 billion (US$285 million) (comprising combined estimated credits for 2023, 2024 and H1 2025), has been recognised in cost of sales for the US PGM mining and recycling operations for the period, benefiting cost and boosting profitability for H1 2025, with associated cash payments expected in 2026.

Improved operational profitability and cash flow, together with effective balance sheet management and reinforcement measures implemented during 2024, has enhanced the Group financial position, and I am satisfied that the Group is well positioned to thrive under multiple scenarios and to create ongoing shared value for stakeholders.

SAFE PRODUCTION AND OPERATIONAL EXCELLENCE

I am particularly pleased with the continued improvement in most of the Group's key safety statistics and performance, especially while navigating a challenging environment and through a disruptive period of restructuring and change.

The ongoing focus on managing risks at our operations, with a specific emphasis on our fatality elimination strategy and reducing High Potential incidents (HPIs), has resulted in trends in both leading and lagging safe production indicators continuing to improve.

The Group Total Recordable Injury Frequency Rate (TRIFR) of 3.90 per million hours worked for H1 2025 was 12% lower than for H1 2024 and was the lowest level reached for TRIFR since we began tracking it in 2020. Group Serious Injury Frequency Rate (SIFR) and TRIFR have both shown favourable compound annual declines of 14% and 16% respectively over the past 3 1/2 years. The Group Fatal Injury Frequency Rate (FIFR) for H1 2025 of 0.038 improved by 5% year-on-year (H1 2024 of 0.04) and was 24% lower than the 3-year trailing FIFR, representing a sustained improvement in safety across the Group since 2022.

Despite the general reduction in the Group lagging indicators, the loss of three colleagues from the SA region during H1 2025 (H1 2024: 3) is an ongoing reminder that we still have a challenging journey to achieve our goal of zero harm. We mourn the tragic loss of these employees and will continue to focus on the implementation of our fatal elimination strategy to maintain our safe production focus.

The Board and management of Sibanye-Stillwater extend their sincere condolences to the loved ones, families and friends of our deceased colleagues.

We are also progressing the Group wide culture and values programmes, which is necessary in our view to achieve a step up in safe production by changing risky behaviours and driving values based decisions throughout the Group.

OPERATIONAL EXCELLENCE AND OPTIMISING PROFITABILITY

All Group operations other than the SA gold operations are on track to deliver safe production and unit costs within annual guidance ranges for 2025, as well as improved profitability. Only the SA gold operations fell short of planned production and cost levels, but continued to benefit from leverage to the increasing gold price during H1 2025, delivering a significantly improved financial contribution.

The SA PGM operations continued to deliver steady and reliable results, as they have done consistently since they were acquired and integrated into the Group. Since 2016, the SA PGM operations have met or exceeded annual guidance every year, other than in 2022, when unanticipated stage 6 load shedding by Eskom from September 2022 severely disrupted the entire SA mining industry.

Production from the SA PGM operations (including attributable production from Mimosa and purchase of concentrates (PoC)) for H1 2025 was 4% lower year-on-year due to surface production declining by 30% year-on-year, primarily due to heavy rainfall during Q1 2025 which disrupted PGM production throughout the SA PGM industry. Underground production was flat year-on-year.

Costs were well managed and reflected the benefits of the restructuring of high cost shafts and closure of end-of-life shafts during H1 2024. Total operating cost increased by 4% year-on-year , well below average mining industry inflation rates. Unit operating costs were 7% higher and AISC 11% higher year-on-year, primarily due to lower surface production and by-product credits (chrome) due to heavy rainfall, as well as an increase in inventory in H1 2025. The change in the Kroondal processing arrangement with Anglo Platinum (Valterra), from Purchase of Concentrate (PoC) to toll refining from August 2024 and ongoing inventory build in the smelting and refining pipeline, also introduced additional cost, although revenue benefited from increased 4E PGM production relative to the PoC arrangement. The inventory accumulated during H1 2025 is forecast to be processed during Q3 2025, and is expected to boost metal sales for H2 2025.

Focussed cost management has continued to drive the SA PGM operations down the industry cost curve significantly enhancing their competitive position relative to industry peers.

Adjusted EBITDA from the SA PGM operations of R4.8 billion (US$260 million) for H1 2025 was in line with H1 2024, despite 151,863 4Eoz (16%) less 4E PGM sold year-on-year. A 7% higher average basket price received for H1 2025 offset lower metal sales. The inventory built-up during H1 2025, is expected to be processed and sold in H2 2025. Compared with H2 2024, adjusted EBITDA for H1 2025 was 81% higher, primarily driven by a 10% increase in the average 4E basket price.

PGM prices have rallied sharply since May 2025 with the average rand 4E basket price for Q3 2025 to date of R31,328/4Eoz, 16% higher than for H1 2025. The SA PGM operations are highly leveraged to the 4E basket price, and should these higher prices persist during H2 2025, a material increase in earnings and cash flow from the SA PGM operations is expected.

The restructuring of the US PGM operations during Q4 2024 was successfully implemented, with production and cost for H1 2025 ahead of planned restructuring levels and, on an annualised basis, better than 2025 guidance.

The profitability of the US PGM operations also improved despite lower metal sales due to a build-up of inventory during the smelter transition in Q2 2025 and an average 2E PGM basket price for H1 2025, that was less than 1% higher than for H1 2024. On a like-for-like basis, adjusted EBITDA (excluding S45X credits) for H1 2025 improved by US$8 million (R273 million) to a loss of US$9 million (R51 million), compared with an adjusted EBITDA loss of US$16 million (R324 million) for H1 2024 (excluding the once off US$43 million (R812 million) insurance payment during Q1 2024, related to the mid-2022 flooding event).

Sibanye-Stillwater Operating and financial results | Six months ended 30 June 2025 3

The average 2E PGM basket price for Q3 2025 to date is US$1,229/2Eoz. This is 25% higher than the average for H1 2025 of US$985/oz and 9% below AISC (excluding S45X credits) of US$1,351/oz. Similarly to the SA PGM operations, if higher PGM prices persist, the profitability of the US PGM operations should increase substantially.

During Q2 2025, agreement was reached with the contract refiner with both parties signing certification statements reflecting this agreement. Consequently, total S45X credits of US$159 million (R2.8 billion) for the PGM underground operations, were recognised during Q2 2025, comprising a credit against cost of US$20 million (R360 million)) for H1 2025 and full year credits of US$70 million (R1.2 billion) and US$69 million (R1.2 billion) for 2023 and 2024 respectively, significantly benefiting cost and profitability for the US PGM operations for the period.

Adjusted EBITDA for the US PGM operations including just the H1 2025 S45X credit of US$20 million (R360 million), would have increased to US$11 million (R309 million). Combined with the full S45X credits for 2023 and 2024, adjusted EBITDA for the US PGM operations increased substantially to US$151 million (R2.8 billion) for H1 2025, 457% higher than for H1 2024.

The realisation of S45X credits at the US PGM mining and recycling operations will provide critical financial support for these strategically important operations before phasing out from 2031 and is a welcome affirmation of the appropriateness of our strategic positioning, guided by our recognition in 2021 of multi-polarity as a likely force driving future global change.

The long term viability of the operations however requires AISC to be reduced below US$1,000/2Eoz (excluding S45X credits) and this is the primary focus of the management team. We remain confident that this target is achievable within the next two to three years.

The SA gold operations are highly leveraged to the dollar gold price and rand:dollar exchange rate. Despite operational challenges which reduced production by 13% year-on-year, adjusted EBITDA for H1 2025 increased by 118% to R4.8 billion (US$260 million) from R2.2 billion (US$117 million) for H1 2024, driven by a 36% year-on-year increase in the average received gold price to R1,802,580/kg (US$3,049/oz). This is the highest adjusted EBITDA from the SA gold operations since H2 2020, and accordingly, the contribution from the SA gold operations to Group adjusted EBITDA for H1 2025 (excluding total S45X credits) increased to 48% from 33% for H1 2024, confirming the strategic importance of the SA gold assets in the diversified Group portfolio.

Gold production from the managed SA gold operations (excluding DRDGOLD) decreased by 14% primarily due to ongoing challenges at the Kloof operation, with AISC for H1 2025, increasing by 17% due to 21% lower gold sold year-on-year.

The average gold price received by the SA managed operations for H1 2025 (including gold hedges), increased by 33% to R1,756,996/kg (US$2,972/oz), significantly enhancing operational profitability. Adjusted EBITDA (excluding DRDGOLD) increased by 166% to R3.0 billion (US$160 million) compared to R1.1 billion (US$59 million) in H1 2024.

Operational challenges which affected the Driefontein and Beatrix operations during Q1 2025, have largely been resolved and both operations are expected to deliver improved production for H2 2025. Seismicity and infrastructural constraints which impacted production from the Kloof operation, are being addressed. A detailed review of the Kloof operational outlook is currently being undertaken to balance the sustainability and commercial viability of these operations, underpinned by our commitment to safe production.

The outlook for the gold price remains positive, supported by uncertain global economic and socio-political factors. The average rand gold price for Q3 2025 to date is 7% higher than for H1 2025, suggesting positive potential for further expected profitability gains during H2 2025.

When the three SA gold operations, Beatrix, Kloof and Driefontein, were unbundled by Gold Fields, they were perceived as troubled, high cost, end of life assets (with reserves of approximately 13.5 Moz and a forecast life of mine (LOM) of around 8 years at the time). In February 2013 Sibanye Gold listed on the JSE at a market capitalisation of around R10 billion. It is therefore encouraging to consider that our managed gold operations (essentially these same assets plus Cooke surface operation), 12 years later, and after producing 12.9 Moz of gold, are still able to deliver adjusted EBITDA of R3.0 billion (US$160 million) for H1 2025. This amounts to roughly 16% of original market capitalisation (R18.75 billion adjusted for inflation) in 6 months. Whilst they are indeed nearing the end of their productive lives, these assets have sustained the Group through a challenging time of low industrial metal prices and are still expected to have between 4 to 10 years of significant shared value potential ahead.

Our circular economy assets are also proving to be a valuable differentiator for the Group, providing consistent earnings through commodity price cycles.

Our secondary mining operations continued to contribute positively to the Group. DRDGOLD’s leverage to the increasing gold price was evident in a 70% increase in adjusted EBITDA to R1.8 billion (US$100 million) for H1 2025 compared with H1 2024, despite an 8% decrease in production. DRDGOLD declared a record final cash dividend of 40 SA cents per share for the year ended 30 June 2025, approximately R178 million of which will accrue to Sibanye-Stillwater.

The Century zinc retreatment operations in the Australian region also performed strongly, with production 22% higher year-on-year and AISC 21% lower. Adjusted EBITDA of US$36 million (R657 million) for H1 2025 was a substantial turnaround from the adjusted EBITDA loss for H1 2024 of US$19 million (R351 million), reflecting an all-round good performance and greater operational stability through measures implemented to sustain production through the wet season that had affected production in previous years.

The recycling business provides earnings stability and consistent cash flow support for the Group, maintaining relatively stable margins through the cycle, but remaining leveraged to increases in metal prices and volumes.

The US PGM recycling operation was stable year-on-year, with recycling constrained by low automobile scrappage rates. The average 3E PGM recycling basket price of US$1,311/3Eoz (R24,109/3Eoz) for H1 2025 was 5% higher than for H1 2024, partially offsetting 14% lower 3E PGM ounces sold due to a build up of inventory during the smelter transition.

As a result of lower 3E sales (and build up in inventory), on a like-for like basis, adjusted EBITDA (excluding S45X credits) of US$4 million (R150 million) was 55% lower year-on-year. Excess inventory is expected to be processed and sold during H2 2025 and, benefiting from higher average PGM prices for Q3 2025 to date, boosting revenue for the coming period.

The US PGM recycling operations also qualify for S45X credits, which boosted adjusted EBITDA for H1 2025 by US$121 million (R2.2 billion) to US$129 million (R2.4 billion). The total credits of US$126 million (R2.2 billion) comprised US$16 million (R289 million) for H1 2025, US$40 million (R711 million) for 2024 and US$69 million (R1.2 billion) for 2023.

The Reldan recycling operation generated adjusted EBITDA of US$18 million (R330 million) for H1 2025, 20% higher than for H2 2024, the previous full 6-month period since it was incorporated into the Group in March 2024. Revenues benefited from higher gold and silver prices during the period.

Sibanye-Stillwater Operating and financial results | Six months ended 30 June 2025 4

In our EU region, the ramp down of the Sandouville refinery is nearing completion and preparation for the care and maintenance phase is ongoing. Production of nickel cathode and nickel salts from nickel matte was stopped by end of Q2 and only some areas of the down stream process remain open to allow for recycling and recovery of nickel from the effluents. Adjusted EBITDA losses of US$17 million (R310 million) for H1 2025 are expected to reduce once the operations are on care and maintenance.

The GalliCam project prefeasibility study is expected to be completed around year end.

The Keliber lithium project remains on track for completion of the construction phase during H1 2026. 2025 marks the peak of project capital expenditure, with capital commitments forecast to decline significantly from H1 2026.

The Keliber lithium project remains the most advanced, fully integrated lithium hydroxide project in the EU region, offering a significant competitive advantage for value realisation in a more supportive price environment. In light of revisions to medium term lithium market fundamentals and price forecasts, we are currently assessing various scenarios to ensure that a decision on the full commissioning and production build up, is adequately informed and responsible, with a primary focus on timing of market entry to optimise value.

FINANCIAL HEALTH

The Group is in a sound financial position. Balance sheet ratios are healthy, secured by capital reinforcement and disciplined capital allocation during 2024, underpinned by improving operational profitability and cash flows. With precious metals prices well supported, the projected outlook for key financial health indicators is positive.

Greater operational stability and good cost control from most Group operations, combined with the leveraged exposure of our SA gold operations to the increasing gold price, have notably improved Group profitability.

Importantly, this upward trend in Group profitability reflects the benefits of repositioning and restructuring of operations which stabilised production and cost from most Group operations, which underpinned a 51% increase in Group adjusted EBITDA (excluding all S45X credits) to R10.0 billion (US$533 million) for H1 2025 from adjusted EBITDA of R6.6 billion (US$355 million) for H1 2024.

The financial turnaround for H1 2025 was significantly amplified by the incorporation of Advance Manufacturing Production credits in terms of Section 45X of the Inflation Reduction Act (IRA), which have been secured for the US PGM operations following agreement reached with the US PGM third party refiner.

S45X credits for both the US underground and recycling operations for FY2023, FY2024 and H1 2025 totalling R5.1 billion (US$285 million) were recognised during Q2 2025, boosting Group adjusted EBITDA (including S45X credits) to R15.1 billion (US$818 million), 127% higher than adjusted EBITDA of R6.6 billion (US$355 million) for H1 2024, albeit not directly comparable year-on-year.

The same positive trend was reflected in Group adjusted free cash flow (FCF), which improved by R12.4 billion (US$610 million) to positive FCF of R4.5 billion (US$243 million) for H1 2025, from a free cash outflow of R6.9 billion (US$367 million) for H1 2024.

Group FCF was boosted by the R9.2 billion (US$500 million) proceeds from the Franco Nevada streaming transaction, concluded in February 2025. Excluding the streaming proceeds would have resulted in a R4.7 billion (US$258 million) FCF outflow for the Group for H1 2025. This is still substantially improved compared with H1 2024, despite the substantial buildup of inventory at the gold and PGM operations which reduced metal sales and FCF from these operations during H1 2025. This inventory is expected to be processed during H2 2025, enhancing cash flow for the period.

The Group’s cash balance (excluding Burnstone) increased by 31% from 31 December 2024 to R21.0 billion (US$1.1 billion) at 30 June 2025, primarily due to the streaming proceeds.

Gross debt (excluding Burnstone) increased by 2% to R40.2 billion (US$2.3 billion) at 30 June 2025, primarily due to project capital expenditure at the Keliber Lithium project.

Net debt decreased by R4.2 billion (US169 million) to R19.2 billion (US$1.1 million) at 30 June 2025, which together with the a 64% increase in the 12 month trailing adjusted EBITDA to R21.5 billion (US$1.2 billion), resulted in the Group’s net debt to adjusted EBITDA reducing to 0.89x, which is pleasing considering substantial capital investment in key projects through the price cycle.

The Group financial position is robust, with sufficient balance sheet liquidity headroom of R46.9bn (US$2.6bn), debt maturities which are well structured and undemanding, Group net debt:adjusted EBITDA which is within comfort levels and well below debt covenant levels. SA gold and SA PGM operations are expected to deliver improved operating results during H2 2025. Metal sales for the period are likely to be enhanced by a release of inventory built up during H1 2025. The US PGM operations are similarly expected to benefit from a release of inventory and higher metal sales for H2 2025.

The SA gold operations and SA and US PGM operations are highly leveraged to metal prices as is evident from the sharp increase in profitability for H1 2025, despite relatively modest metal price increases. Gold and PGM prices have rallied further during Q3 2025 (for Q3 2025 to date, averaging R1,934,171/kg (+5%), R31,328/4Eoz (+19%) and US$1,229/2Eoz (+25%)), which suggests significant upside for earnings and cash flow should higher prices be maintained.

The Group cash position will be further enhanced in 2026, by the expected R4,404 million (US$248.5 million) S45X credits cash payment to the US PGM operations.

Losses from the Sandouville refinery are also anticipated to decline when the facility is placed on planned care and maintenance at year end.

Furthermore, as detailed in the Q1 2025 operating results, Group cash flow is expected to benefit from substantially reduced annual project capital expenditure for the Keliber lithium project (from capital guidance of €300 million (R5.9 billion) for 2025), following the forecast completion of the construction/development phase of the Keliber lithium project, scheduled for H1 2026.

The Marikana K4 shaft is also nearing completion of the project phase, with project capital expected to decline from current levels of R309 million (US$17 million) for H1 2025, and its contribution to revenue from the Marikana operation, increasing as production continues to ramp up.

As such, there is a high probability that cash flow for H2 2025 and FY2026 could increase substantially, supporting a reduction in Gross debt, which will further strengthen the Group financial position, and provide for increased dividends to shareholders.

STRATEGIC POSITIONING

I am confident that the proactive and decisive actions taken over the past 2 years to optimise operational profitability and secure the financial sustainability of the Group through an extended trough in commodity prices, have successfully managed risk and aided in preserving value.

The decisions we took and actions we implemented were not taken lightly, but were deeply considered and measured, avoiding knee-jerk responses to the deteriorating environment, before being decisively implemented.

We approached the restructuring in a phased and considered manner, focusing on high-cost mines to restore profitability and ensure their survival, and closing shafts which were at, or close to, the end of their operating lives, or unable to restructure effectively.

Our strategic positioning in the US, European and Australian ecosystems has been guided by our recognition in 2021 that the global trade model was unsustainable and that there would be a shift towards establishment of regional value chains, which we called multipolarity. We anticipated that achieving greater trade independence would require significant financial support and investment from regional governments, which would benefit strategically positioned businesses.

This led to us keeping the US PGM operations in production at reduced scale despite sentiment from some analysts and investors that they should be shut down. I am pleased to say this appears to be the right decision by the Group. The US PGM operations are the only source of primary PGM supply in the US and are of strategic importance not just for Sibanye-Stillwater, but for the US. The phased repositioning and restructuring we implemented at these operations since 2022, together with the S45X credits, which will provide critical financial support for the next 8 years, has already enhanced their potential sustainability.

The Group filed anti-dumping and countervailing duty petitions on unwrought Palladium from Russia on 30 July 2025, following significant engagement with the US Treasury. The petition was filed together with the United Steelworkers Union and with support from over 70% of US Palladium value chain participants.

The purpose of US anti-dumping and countervailing duty law is to ensure that domestic producers can compete on a level playing field by addressing market distortions caused by unfair trade practices. Parallel investigations by the US Department of Commerce and the US International Trade Commission will take about 13 months although preliminary duties may be imposed within five months of the filing.

The rationale for our application is to protect a strategic asset for the US and protect our US PGM operations from uneven trade practices, for the benefit of stakeholders including employees and communities in Montana.

Our projects in the European region, the Keliber lithium project and GalliCam project, have both been granted ‘strategic project’ status under the EU critical raw materials act (CRMA), with the GalliCam project having been awarded a conditional grant of €144 million from the European Innovation Fund.

While taking decisive action to improve operational profitability and reinforce our Balance sheet, and despite the trough in prices, we continued to invest in key projects that were approved and were under development, such as the Marikana K4 project and the Keliber lithium project. Both of these projects are well advanced, with the K4 project in the production buildup phase, with project capital expenditure reducing, and the Keliber lithium project nearing completion of the construction phase.

The K4 project at Marikana operations is a world class PGM project with a LOM of more than 30 years that was substantially developed with capital invested by Lonmin before it was put on care and maintenance in 2015/16. Sibanye-Stillwater resumed project development in 2021 and it has significantly advanced, with the ramp up of production to full production of 250,000 4Eoz underway for three years already, steadily increasing its contribution to Marikana production and reducing unit costs.

The Keliber lithium project remains the most advanced, fully integrated lithium hydroxide project in the EU region, offering a significant competitive advantage for value realisation by supplying locally mined and beneficiated critical metals to the European battery ecosystem.

The lithium market has been in surplus since 2023, which has continued to weigh on lithium prices during H1 2025. Despite lithium prices falling well into the industry cost curve, there has been limited response from producers. Absent any material supply response, the lithium market is forecast to remain in surplus for longer, extending the trough in prices. Despite a slowdown in forecast battery electric vehicles (BEV) sales growth, lithium demand is expected to continue to increase steadily, albeit at a reduced rate than previously projected by the market. Our fundamental long-term outlook for the lithium market therefore remains unchanged, however these factors have contributed to a more extended period of oversupply and low prices, than previously forecast.

We successfully funded these projects through peak capex phases, while maintaining our financial integrity, contrary to expectations of many market commentators. Project capital requirements for these projects are forecast to decrease significantly during 2026, enhancing cash flow. Further to investing in these key projects through the cycle, opportunities to optimise the potential of the SA PGM operations continue to be assessed.

The acquisition of Valterra's 50% share in the Kroondal PSA and full consolidation of Kroondal into the Rustenburg operation during H2 2024, allows opportunities for further synergies and value unlock, in addition to the cross boundary mining already taking place. During Q2 2025, the Board approved the Bambanani-Siphumelele project as the next step in realising value from this acquisition. This brownfield project involves the extension of the Bambanani decline allowing extraction of Siphumelele UG2 reserves from low cost mechanised Bambanani infrastructure. The Siphumelele vertical shaft provides more efficient man and materials logistics resulting in significant cost benefits for both operations. This logical, relatively low capital intensity project, is expected to deliver extend the life of both the Siphumelele and Bambanani mines, and forecast to deliver quick payback of invested capital, thereby ensuring high returns for the Group and unlocking of shared value for all stakeholders.

Low capital intensity,brownfields projects such as this are a logical continuation of the consolidation of our SA PGM assets which began in 2016 and offer significant potential to maintain higher production from these assets over a longer LOM than currently planned, through the realisation of further operational and cost synergies. There is also significant potential to reprocess extensive surface resources, which is currently being assessed and is expected to extend the life of the surface operations significantly.

The agreement announced on 19 February 2025 regarding the Glencore/Merafe JV is expected to significantly increase chrome yields and production from the SA PGM operations, and accelerate completion of delivery of contracted chrome volumes agreed in 2011 between Lonmin and the Glencore/Merafe JV Venture, by approximately 20 years. Thereafter, Sibanye-Stillwater's attributable share of value from chrome production from the Marikana CRPs is expected to be significantly enhanced from greater exposure to chrome prices, and anticipated future chrome production growth. The improved economics of Sibanye-Stillwater's chrome production are expected to enhance the inherent value and commercial viability of development and extension brownfields projects at the SA PGM operations, which are currently being assessed.

SIBANYE-STILLWATER GROUP SAFETY AND OPERATING REVIEW

SAFETY

It is pleasing to note the improvement in most Group safety indicators year-on-year. The Group lost time injury frequency rate (LTIFR) improved from 3.99 (per million hours worked) for H1 2024 to 3.57 for H1 2025, a 11% improvement and the Total recordable injury frequency rate (TRIFR) decreasing from 4.45 to 3.90 (per million hours worked) for the same period. The Group serious injury frequency rate (SIFR) regressed slightly by 1% from 2.20 (per million hours worked) for H1 2024 to 2.23 for H1 2025.

During H1 2025, the Group achieved its lowest TRIFR of 3.90, 12% lower than H1 2024. High potential incidents (HPIs) have also steadily declined since monitoring began in H2 2022.

It is essential to equip leaders and line managers to address unintentional human errors and to actively promote and reinforce safe production practices. Supporting the existing leadership development programs, Sibanye-Stillwater iCARES values and behavioural frameworks, a focused safety culture uplift programme has commenced in the SA region to change behaviours and sustainably improve safe production. In recent years improved risk awareness, operational transparency, and employee confidence in the reporting process has led to a consistent increase in reporting of near-miss incidents. Entrenching our safety strategy and supporting teams to achieve consistent, sustainable, and safe production will continue to be a priority for 2025, along with encouraging values-based decision-making.

Notwithstanding the progress being made through our Fatal elimination strategy, improving cultural maturity at leadership and supervisory levels and enhancing excellence in the monitoring and execution of group minimum technical standards, the loss of any colleague is deeply mourned. On 11 June 2025, Miss Nomsa Matsolo, an employee at our Rustenburg operations passed away from injuries sustained when she was struck by a Sibanye-Stillwater contractor vehicle whilst conducting road barrier maintenance on a surface public road maintained by Sibanye-Stillwater. This together with the loss of Mr. Xavier Humberto, a 58 year old shaft timberman at Kloof 1 shaft and Miss Bomkazi Jozana, a 31 year old locomotive operator at Driefontein 5 shaft, during Q1 2025, a total of three fatalities were experienced during H1 2025. All incidents have been investigated with relevant stakeholders to understand the root causes and specify risk mitigation measures for implementation.

The Board and management of Sibanye-Stillwater extend their sincere condolences to the loved ones, families and friends of our deceased colleagues, and support has been provided to the families of the deceased.

OPERATING REVIEW

Americas (US) region

US PGM operations

During H1 2025, the US PGM operations successfully delivered on the the planned operational parameters from the restructuring from Q4 2024, reducing absolute cost and improving profitability. Management is now focused on reducing AISC to below US$1,000/2Eoz (in 2024 real terms and excluding S45X credits). This Group aims to achieve this reduction through a combination of improved productivity, efficiency enhancements and continuous optimisation of cost and operating efficiency. The focus includes a review of mining cycles, additional mechanising activities and improvements to mine infrastructure and design.

Mined 2E PGM production for H1 2025 of 141,124 2Eoz was 41% lower year-on-year, primarily due to the cessation of operations from the Stillwater West mine, which has been put on care and maintenance as planned. On an annualised basis (282,248 2Eoz) the operations are on track to deliver within annual production guidance of 255,000 2Eoz to 270,000 2Eoz for 2025. 2E PGM production from the Stillwater mine of 75,898 2Eoz for H1 2025, was 51% lower than for H1 2024, reflecting the suspension of operations at the Stillwater West mine with production from the East Boulder mine of 65,225 2Eoz, 21% lower year-on-year, in line with the restructuring plan.

2E PGMs sold of 133,106 2Eoz for H1 2025 were 8,018 2Eoz less than PGMs produced as a result of the start-up and commissioning of the second electric furnace (EF2), which commenced processing in April 2025, replacing electric furnace 1 (EF1), which decommissioned in July 2025. During the commissioning in Q2 2025, throughput was temporarily constrained, resulting in a higher inventory in process, especially inventory shipped for final refining compared to end 2024. Inventory lock-up of approximately 5,700 2Eoz during the commissioning of EF2 is expected to be partly offset by the release of locked up inventory from EF1 as it is dismantled in H2 2025.

Total capital expenditure decreased by 52% year-on-year to US$45 million (R829 million). Ore reserve development (ORD) expenditure declined by 49% to US$33 million (R614 million) and sustaining capital decreased by 68% to US$7 million (R121 million) for H1 2025. Sustaining capital is expected to be higher in H2 2025 as projects are completed and new fleet items are delivered. Project capital for H1 2025 of US$5 million (R94 million) was primarily on the construction of the East Boulder tailings storage facility.

While it did not have a substantial impact on H1 2025 production, a fall of ground incident occurred at a high grade stope block at Stillwater East at the end of April 2025, which is expected to be back in production in September 2025. Alternative stope blocks have been developed to address the shortfall of around 3,000 2Eoz per month. Whilst our guidance for 2025 is unchanged, the incident is likely to result in lower production in the second half of the year compared to H1 2025.

US recycling operations

US PGM recycling operation

Average volumes of spent autocatalysts fed at the US PGM recycling operation of 9.6 tonnes per day (tpd) for H1 2025 were 10% lower when compared to H1 2024 feed rates of 10.7 tpd. The transition from the EF1 furnace to the new EF2 furnace at the Columbus metallurgical facility resulted in lock-up in recycling inventories. At the end of H1 2025, recycle inventory increased to approximately 147 tonnes containing an estimated 12,000 3Eoz compared with 62 tonnes at the end of H2 2024. Inventory levels reduced in July and the smelter is expected to process this excess inventory to a sustainable level of around 60 tonnes during H2 2025.

Total recycling S45X credits of US$126 million (R2.2 billion) were recognised during Q2 2025 which included full year credits of US$69 million (R1.2 billion) and US$40 million (R711 million) for 2023 and 2024 respectively, and US$16 million (R289 million) for H1 2025, significantly benefiting profitability for the US PGM recycling operations for the periods.

Sibanye-Stillwater Operating and financial results | Six months ended 30 June 2025 8

The average 3E PGM recycling basket price of US$1,311/3Eoz (R24,109/3Eoz) for H1 2025 was 5% higher than for H1 2024, partially offsetting lower 3E PGM ounces sold which decreased by 14% to 135,432 3Eoz. Adjusted EBITDA (excluding the S45X credit) for H1 2025 of US$4 million (R150 million) was 55% lower than for H1 2024. Adjusted EBITDA (including the S45X credits) for H1 2025 was US$129 million (R2.4 billion), 16 times higher than the US$8 million (R147 million) for H1 2024. For H2 2025, as the excess inventory is processed and sold, the outlook for the recycling operations is very favourable.

Reldan recycling operations

For H1 2025 Reldan processed 8.6 million lb of mixed scrap and sold 63,992 oz gold, 932,712 oz of silver, 8,020 oz platinum, 11,557 oz palladium, and 1.5 million lb of copper.

Adjusted EBITDA of US$18 million (R330 million) from the Reldan recycling operations for H1 2025 was 20% higher than for H2 2024, the first full half year since it was incorporated into the Group.

Southern Africa (SA) region

SA PGM operations

The SA PGM operations delivered another solid performance for H1 2025. 4Eoz PGM production (including attributable production from Mimosa and third party purchase of concentrate (PoC)) of 840,046 4Eoz, was 4% lower year-on-year, primarily due to 30% or 23,294 4Eoz lower surface production which decreased to 54,102 4Eoz as a result of high seasonal rainfall which impacted most of the SA PGM industry, and 29% (14,352 4Eoz) lower PoC purchases of 35,794 4Eoz, in line with revised annual contractual agreements. The Rustenburg surface operations were also impacted by challenging re-mining conditions at the Waterval West TSF which is expected to reach the end of its life in 2026, and the supply of high grade slag from Valterra Platinum Limited which stopped in February 2025. PGM production (including attributable production from Mimosa and excluding PoC) declined by 3% to 804,252 4Eoz. PGM production from underground operations of 750,150 4Eoz for H1 2025 was in line with H1 2024 with underground production from the Rustenburg operations 2% higher and from the Marikana operations 1% lower. With the exception of Kwezi shaft (Kroondal), all underground shafts increased production for Q2 2025 relative to Q1 2025.

H1 2025 costs were well contained with total SA PGM operating costs (excluding PoC and Mimosa) increasing by only 4% to R19.3 billion (US$1.1 billion). These cost controls include the benefits from the restructuring and closure of high costs shafts in Q1 2024 which has ameliorated additional toll processing costs resulting from the move of the Kroondal operations from PoC to toll with effect from 1 September 2024. As previously highlighted, with the transition from PoC to toll, Kroondal, now incorporated in Rustenburg, has higher operating costs due to increased tolling costs compared to the PoC agreement where smelting and refining costs were not reflected in operating costs, but in reduced revenue, and with the move to tolling at Kroondal, Kroondal will derive greater exposure to the higher metal prices and achieve higher margins as sales are realised.

AISC (excluding PoC) for H1 2025 at our managed operations increased by 11% year-on-year to R23,892/4Eoz (US$1,299/4Eoz), in line with the annual guidance range of R23,500 to R24,500/4Eoz (US$1,288 and 1,342/4Eoz). The increase was primarily due to 3% lower production, a 20% increase in sustaining capital (specifically Marikana) and 11% lower by-product credits (primarily Rustenburg) compared with H1 2024. By-product credits (including PoC), which in H1 2025 contributed R6,732/4Eoz (US$366/4Eoz) to AISC were lower primarily due to lower chrome production and sales volumes (affected by rainfall during Q1 2025) and a 13% decrease in the chrome market price. Chrome sales revenue as a percentage of by-products declined from 53% in H1 2024 to 41% in H1 2025. AISC (including PoC) at our managed operations increased by 11% year-on-year to R23,777/4Eoz (US$1,293/4Eoz), with PoC purchase costs 15% lower due to lower contractual purchase volumes.

Total capital expenditure remained consistent with H1 2024 at R2.5 billion (US$138 million). ORD capital expenditure decreased by 7% to R1.1 billion (US$60 million). Sustaining capital expenditure increased by 20% to R1.1 billion (US$61 million) attributable to increased spending on infrastructure projects, winder upgrades, and the refurbishment of the Other Precious Metals (OPM) and Ruthenium plant at the Precious Metal Refinery (PMR). Growth project capital decreased by 25% to R332 million (US$18 million) due to the Marikana K4 project capital declining in line with the project schedule.

4E PGM sales were 16% lower year-on-year (primarily due to smelter rebuilds at Furnace 1 and 2 at Marikana and the secondary precious metal circuit at the Precious Metals Refinery), resulting in a build up in inventory, which is expected to be processed during Q3 2025. Given the improving production and sales outlook in H2 2025 and the PGM basket price which has improved by 23% since the end of May to the current level of R31,627/4Eoz, the outlook for the SA PGM’s operations is very positive.

Attributable PGM production from Mimosa of 59,054 4Eoz was 4% lower as a result of maintenance shutdowns at the metallurgical plant, which also impacted recoveries. AISC increased by 4% to US$1,193/4Eoz (R21,946/4Eoz) as a result of lower production, offset by sustaining capital which was 44% lower at US$9 million (R160 million) following the commissioning of the new tailings storage facility (TSF) in April 2024. Mimosa concentrate sales were temporarily affected by the suspension of exports from Zimbabwe during April and May 2025.

Chrome sales in H1 2025 of 1,072kt decreased by 17%, mainly due to a 12% decrease in chrome production to 1,162kt, significantly impacted by high rainfall during Q1 2025. Chrome revenue of R2.2 billion (US$117 million) decreased by 31% or R1.0 billion due to a 13% decrease in received chrome price which declined from US$298/t for H1 2024 to US$259/t along with the lower sold volumes.

SA gold operations

For H1 2025, gold production from the managed SA gold operations (excluding DRDGOLD) decreased by 14% to 7,072 kg (227,370 oz), primarily due to ongoing challenges at the Kloof operation, including increased seismicity in high grade, isolated blocks of ground, along with infrastructure limitations in the shaft ore pass and ventilation systems at Kloof Thuthukani 1 shaft. These issues have resulted in start-stop operations that further impact stability of production. Compounding this were two significant incidents: a tragic fatal accident at Thuthukani 1 Shaft in January together with a Section 54 stoppage, resulting in a loss of approximately 25,000 oz less production, and a shaft incident in May 2025 at Manyano 7 shaft, which was only resolved in July 2025 contributing a further 2,000 oz production shortfall. The Kloof operation is currently under comprehensive review to optimise the mine plan for long term stability and commercial viability, within the context of our steadfast commitment to safe production practices.

Production from the Driefontein operations was impacted by a fire in a 5 shaft pump station in January 2025; and a Section 54 stop order following the fatal incident in March 2025, which delayed the post fire ramp-up. Seismicity in high grade VCR stopes at Driefontein 1 shaft necessitated crew withdrawals and reassignments to lower grade areas also impacted delivery in H1 2025. Beatrix underground production was consistent with H1 2024, although plant leach train and elution constraints (resolved by end H1 2025) reduced throughput and production for the period. Accumulated inventory, will be processed during H2 2025. Production from the SA Gold operations (including DRDGOLD) for H1 2025 of 9,337kg (300,191 oz) was 13% lower than for H1 2024.

Sibanye-Stillwater Operating and financial results | Six months ended 30 June 2025 9

AISC (excluding DRDGOLD) for H1 2025, increased by 17% to R1,561,114/kg (US$2,640/oz) compared to H1 2024, primarily driven by 21% lower gold sold year-on-year with gold sold 175 kg (5,626 oz) lower than gold produced for H1 2025 due to timing differences. AISC including DRDGOLD for H1 2025 of R1,436,817/kg (US$2,430/oz) was 15% higher year-on-year.

The average gold price received by the SA managed operations for H1 2025 (including gold hedges), increased by 33% to R1,756,996/kg (US$2,972/oz), significantly enhancing operational profitability. Adjusted EBITDA (excluding DRDGOLD) increased by 166% to R3.0 billion (US$160 million) compared to R1.1 billion (US$59 million) in H1 2024. Adjusted EBITDA including DRDGOLD increased by 118% to R4.8 billion (US$260 million), the highest Adjusted EBITDA for the gold operations since H2 2020.

For H2 2025 to date the average spot gold price of R1,910,747/kg (US$3,345/oz) is currently 5% higher than the average spot gold price for H1 2025, which if sustained, suggests increased profitability from the SA Gold operations. A stockpile of ore at the Beatrix operation, containing approximately 92kg (2,958 oz) of gold, is expected to be processed during H2 2025 benefiting production and revenue.

Capital expenditure (excluding DRDGOLD) decreased by 16% to R1.7 billion (US$90 million), primarily due to the Burnstone project being placed on care and maintenance in Q1 2024. Ore reserve development (ORD) capital expenditure was 3% lower to R1.4 billion (US$74 million), driven by reduced off reef development meters at Beatrix and Kloof. Conversely, sustaining capital expenditure increased by 2% to R297 million (US$16 million), reflecting increased investment in winder upgrades and infrastructure at Kloof and plant refurbishment at Beatrix.

DRDGOLD’s gold production of 2,265kg (72,821oz) for H1 2025, was 8% lower than for H1 2024 as a result of a 19% decrease in yield, partially offset by a 14% increase in tonnes milled. This was consistent with the planned transition at ERGO to mainly higher volume, lower grade sites, following the depletion of higher-grade remnant sites in the previous year. AISC for H1 2025 increased by 15% to R1,075,966/kg (US$1,820/oz), mainly as the result of a 8% decline in gold sold, and a 50% increase in sustaining capital to R184 million (US$10 million), associated mainly with the construction of water pipeline infrastructure from Ergo’s central water facility to the 4A8 site. Project capital was 53% lower in H1 2025 at R1.1billion (US$60 million) as a result of the completion of the construction of ERGO’s solar power plant and battery power storage facility and less than planned capital spent on the Regional Tailings Storage Facility (RTSF) due to the unprecedented wet weather conditions which inhibited construction activities.

Sandouville nickel refinery

The ramp-down of the Sandouville nickel refinery continued during H1 2025, with production of nickel cathode and salts from nickel matte concluding in Q2 2025. Some areas of the down stream process remain open to allow for the possibility of recovery of nickel from the effluent cake through recycling. A voluntary leave plan has been agreed with the unions and approved by French authorities, and negotiations for further headcount reductions are ongoing.

An adjusted EBITDA loss of US$17 million (R310 million) for H1 2025 was incurred, but this loss is expected to reduce in H2 2025 following the plant being placed on care and maintenance.

The GalliCam pre-feasibility study (PFS) is expected to be completed around year-end. Gallicam prefeasibility costs of US$3 million (R65 million) were expensed in H1 2025, against a forecast of US$11 million (R198 million) for 2025.

Keliber lithium project

Construction of the Keliber lithium project primarily focused on electrical and instrumentation installations at the Keliber lithium refinery, and civil works and equipment installations at the Päiväneva concentrator. Cold commissioning started at both sites during Q2 2025.

Capital expenditure for H1 2025 (including capitalised interest and other capitalised expenditure outside the initial forecast scope of the project, e.g. exploration) was €152 million (R3.1 billion) consistent with guidance of €300 million (R5.9 billion)* for 2025. Forecast project capital expenditure for the total construction phase of the project was revised to €783 million (R15.5 billion) (real 2024 terms) during Q2 2025, of which €577 million (R11.5 billion) had been spent by end of H1 2025.

The Keliber lithium project has received all key permits, however some permit conditions are still subject to further review by the permitting authority:

•The environmental permit (EP) for the Rapasaari-Päiväneva area is legally valid since April 2024 following the Vaasa administrative court ruling which required certain permit conditions to be reviewed by the permitting authority.

•For the Päiväneva concentrator, the permitting authority (Regional State Administrative Agency for Western and Inland Finland) published the permit decision on 24 June 2025, which included an enforcement order allowing the concentrator to be constructed and operate according to schedule. The appeal period ended 31st of July 2025 with 1 appeal submitted against the permit decision. The handling of the appeal in Vaasa Administrative Court is expected to take approximately 9-12 months.

•For the Rapasaari mine, the application concerning the permit conditions subject to further review was submitted in March 2025

* The guidance has been translated where relevant at an average exchange rate of R18.24/US$ and R19.80/€

Century zinc retreatment operation

The Century operation delivered a strong operational performance for H1 2025, producing 51kt of payable zinc, a 22% increase compared with 42kt for H1 2024.

Operational resilience measures to minimise disruption from excessive rainfall which affected H1 2023 and H1 2024 were implemented, and had a resultant positive impact in H1 2025. These included the addition of two satellite slurry-winning pontoons (separate mining systems, on higher elevation and less affected by rain events), additional dewatering infrastructure, an improved debris removal system and additional water diversion bunds.

The AISC for H1 2025 was US$1,762/tZn (R32,411/tZn), 21% lower than US$2,228/tZn (R41,710/tZn) for H1 2024 as a result of the increased production, and good cost control by the operations.

The strong operational performance together with relatively stable A$ zinc prices and low treatment charges for H1 2025, resulted in adjusted EBITDA for the Century operation increasing to US$36 million (R657 million).

Sibanye-Stillwater Operating and financial results | Six months ended 30 June 2025 10

We expect the strong operational performance to continue during H2 2025, post the annual shutdown completed in July, and supported by positive Australian dollar zinc metal pricing and low treatment charges.

An opportunity to extend the life of the Century operation and enhance the return on investment from the assets continues to be actively explored. With the aim of leveraging the existing infrastructure (processing plant, pipeline, camp and port facilities) and some of the extensive, largely undeveloped, high grade phosphate resources in the region, a feasibility study (AACE Class 2 Estimate) is expected to be completed during Q1 2026.

Mt Lyell copper project

The Mt Lyell feasibility study (AACE Class 2 Estimate) is expected to be completed during Q4 2025.

FINANCIAL REVIEW OF THE SIBANYE-STILLWATER GROUP

Group financial performance

Group revenue for H1 2025 decreased by 1% to R54,767 million mainly due to lower sales volumes at all operations with the exception of the Century zinc retreatment and Reldan operations, partially offset by higher gold prices received during H1 2025. Group cost of sales, before amortisation and depreciation decreased by 20% to R38,274 million mainly due to the S45X advanced manufacturing production credits recognised during June 2025 for 2023, 2024 and H1 2025 reporting periods, and lower sales volumes. The lower cost of sales was slightly offset by higher impairments raised, higher share-based payment expenses, lower other income received and a net loss on financial instruments, which resulted in a 44% decrease in the Group loss for H1 2025 of R3,906 million. Group adjusted EBITDA for H1 2025 increased by 127% or R8,425 million to R15,073 million.

Revenue

Group revenue for H1 2025 decreased by 1% or R437 million to R54,767 million. Consolidated group revenue benefited from increased commodity prices, offset by lower volumes at all operations with the exception of the Century zinc retreatment and Reldan operations. Consequently, the impact of both higher commodity prices and volumes resulted in higher revenue at the Century zinc retreatment and Reldan operations of R840 million and R2,523 million, respectively. The Reldan operation also included revenue for two additional months in H1 2025 since its acquisition on 15 March 2024.

Cost of sales, before amortisation and depreciation

Group cost of sales before amortisation and depreciation for H1 2025 decreased by 20% or R9,787 million to R38,274 million. This was mainly due to the recognition of the S45X advanced manufacturing production credits of R5,052 million at the US PGM operations (see section below). Notably, cost of sales before amortisation and depreciation at the US PGM underground operations decreased by R2,366 million or 46%, in line with a 45% decrease in volumes sold by the US PGM operations as they are repositioned for a lower cost structure. Additionally, cost of sales before amortisation and depreciation at the US PGM recycling operations decreased by R422 million or 12%, in line with a 14% decrease in volumes sold. Cost of sales before amortisation and depreciation at the Sandouville nickel refinery decreased by R1,167 million or 61%, mainly due to the termination of nickel production which resulted in a 69% decrease in volumes sold.

S45X Advanced manufacturing production credit

The S45X advanced manufacturing production credits for the US PGM operations recognised cumulatively relating to the 2023, 2024 and H1 2025 reporting periods amounted to R5,052 million (US$285 million) and the split by period and between the US PGM mining and US PGM recycling operations is disclosed in the table below:

Figures in million
Government grant income		Total		H1 2025		FY 2024		FY 2023

US recycling operations		2,227		289		711		1,227
Total S45X credits		5,052		649		1,931		2,472

All values are in US Dollars.

Loss for the period

Loss for H1 2025 decreased by 44% from R7,001 million in H1 2024 to a loss of R3,906 million mainly due to lower net cost of sales arising from the recognition of the S45X advanced manufacturing production credits, a 45% decrease in volumes sold at US PGM underground operations and a 69% decrease in volumes sold at the Sandouville nickel refinery due to the termination of nickel production. The decreased loss for H1 2025 was partially offset by higher impairments (US PGM operations and Keliber, as discussed later in this section), movement in net loss on financial instruments of R1,887 million and share of results of equity accounted investees of R615 million, mainly related to a higher loss from Mimosa due to impairment recognised on property, plant and equipment of R599 million. The loss for H1 2025 was also partially offset by higher share-based payment expenses of R615 million, a function of the share price movement and by lower other income of R816 million. The decrease in other income was mainly due to a reduction in insurance proceeds received of R724 million and a reduction of onerous supply contract provision utilisation/change in estimate at the Sandouville nickel refinery of R200 million. See note 5.2 of the consolidated interim financial statements for additional information on other income.

Adjusted EBITDA

Adjusted EBITDA includes other cash costs, care and maintenance costs, lease payments, strike costs and corporate social investment costs (see note 18 of the consolidated interim financial statements for a reconciliation of profit before royalties, carbon tax and tax to adjusted EBITDA). Care and maintenance costs for H1 2025 were R662 million.

Sibanye-Stillwater Operating and financial results | Six months ended 30 June 2025 14

Interest income

Interest income decreased by R63 million to R686 million mainly due to R232 million lower interest received on average cash balances, partially offset by an increase in interest received from revenue authorities of R162 million.

Finance expense

Finance expense increased by R261 million to R2,553 million mainly due to a R378 million increase in the unwinding of the finance costs on the deferred revenue transactions. See note 3 of the consolidated interim financial statements for a breakdown of finance expenses.

Loss on financial instruments

The loss on financial instruments of R391 million for H1 2025 compared with the gain of R1,496 million for H1 2024, represents a period-on-period net loss of R1,887 million. The net loss for H1 2025 is mainly attributable to a decrease in the fair value gain on the US$ convertible bond derivative financial instrument of R1,733 million following the approval by the shareholders to settle the convertible bond with ordinary shares in May 2024. Also included in the loss for H1 2025 were fair value losses on hedge contracts for gold of R778 million, fair value adjustment on share-based payment obligations of R131 million and fair value losses on other financial instruments of R12 million, partially offset by fair value gains on hedge contracts for zinc of R222 million, revised cash flows of the Keliber dividend obligation of R137 million and other investments of R165 million. See note 4 of the consolidated interim financial statements for a breakdown of the loss on financial instruments.

Impairments

At 30 June 2025, the Group recognised impairments of R9,666 million due to:

•A decrease in the long-term forecast lithium hydroxide price and an increased discount rate resulted in a decrease in the expected future net cash flows and a reduction in the recoverable value from the Keliber lithium project at 30 June 2025, and resulted in an impairment of property, plant and equipment amounting to R5,344 million

•On 4 July 2025 the One Big Beautiful Bill Act was signed into US law which provides for a phase out and termination of the Section 45X credits. Under the phase out and termination rules, the Section 45X credit for any applicable critical mineral will be phased out in equal annual increments of 25% from 2031 to 2034, after which these credits will be terminated. This resulted in a decrease in the expected future net cash flows from the US PGM operation (Stillwater CGU) and an impairment of property, plant and equipment amounting to R3,828 million

See note 6 of the consolidated interim financial statements for additional information on impairments.

Cash and liquidity

The Group’s cash balance (excluding cash of Burnstone1) increased by 31% from R16,002 million at 31 December 2024 to R20,966 million at 30 June 2025 and includes R4,496 million held by the US PGM operations and R8,368 million held by Sibanye-Stillwater UK Financing Plc. The US$500 million streaming agreement with Franco-Nevada generated proceeds of R9,215 million, received on 28 February 2025. Group liquidity was R46,932 million (31 December 2024: R45,683 million), comprising R20,966 million of cash and cash equivalents (31 December 2024: R16,002 million) and R25,966 million of undrawn facilities (31 December 2024: R29,681 million).

Borrowings and net debt

Gross debt1 increased by 2% from R39,426 million at 31 December 2024 to R40,157 million at 30 June 2025. Burnstone debt amounted to R2,254 million (31 December 2024: R2,260 million). The increase in gross debt was mainly due to a drawdown on the Keliber financing facility of R1,868 million, partially offset by a net decrease of R1,223 million on US dollar denominated debt due to a 5% stronger rand since 31 December 2024. Net debt was R19,191 million at 30 June 2025 (31 December 2024: R23,424 million) and decreased by R4,233 million due to the Franco-Nevada streaming proceeds. Refer to note 11 of the consolidated interim financial statements for a roll forward of the gross debt for the six months ended 30 June 2025.

Cash flow analysis

The following table shows a reconciliation from net cash from operating activities to adjusted free cash flow:

Figures in million - SA rand	Six months ended
	H1 2025	H2 2024	H1 2024
Net cash from operating activities	13,177	6,416	3,697
Adjusted for:
Dividends paid	129	87	86
Net interest paid	705	730	489

Additions to property, plant and equipment	(9,538)	(10,422)	(11,147)
Adjusted free cash flow	4,473	(3,189)	(6,875)

Adjusted free cash flow defined below and reconciled above, is not a measure of performance under IFRS Accounting Standards. As a result, it should not be considered in isolation or as alternatives to any other measure of financial performance presented in accordance with IFRS Accounting Standards

The Group realised net cash from operating activities of R13,177 million (H1 2024: R3,697 million) and incurred net cash used in investing activities of R9,156 million (H1 2024: R14,015 million, which includes the acquisition of Reldan net of cash of R2,690 million). Net cash generated from financing activities was R1,453 million (H1 2024: R415 million).

Adjusted free cash flow*

Sibanye-Stillwater defines adjusted free cash flow as net cash from operating activities before dividends paid and net interest paid, less cash additions to property, plant and equipment and excluding intercompany movements.

* Previously Sibanye-Stillwater defined adjusted free cash flow as net cash from operating activities before dividends paid, net interest paid and deferred revenue advance received, less additions to property, plant and equipment

The following table shows the adjusted free cash flow per operating segment:

Figures in million - SA rand	Six months ended
	H1 2025	H2 2024	H1 2024
US PGM operations	(1,561)	(902)	(1,324)

1During H1 2025 revenue related to a Chrome prepayment transaction of R733 million was recognised by the SA PGM operation, but excluded from the adjusted free cash flow above due to the non-cash flow nature thereof. For H2 2024, the adjusted free cash flow includes a cash inflow of R905 million in respect of the deferred revenue advance received relating to the Chrome prepayment transaction, because the cash flows from streaming and prepayment transactions are recognised in the period in which the cash is received.

2H2 2024 adjusted free cash flow relating to the SA gold operations includes R1,793 million proceeds related to a gold prepayment transaction

3The adjusted free cash flow for H1 2025 in respect of Group corporate includes R9,215 million proceeds related to the Franco-Nevada stream which was received in February 2025

4Adjusted free cash flow, defined and reconciled above, is not a measure of performance under IFRS Accounting Standards. As a result, it should not be considered in isolation or as alternatives to any other measure of financial performance presented in accordance with IFRS Accounting Standards

Group net cash inflow from operating activities amounted to R13,177 million compared to R3,697 million for H1 2024. The Group generated adjusted free cash inflow of R4,473 million, mainly due to the cash proceeds relating to the Franco-Nevada streaming transaction which was received during February 2025, as well as attributable to the positive adjusted free cashflow of Reldan, SA gold and Australian operations.

The US PGM operations incurred negative adjusted free cash flow of R1,561 million compared to negative adjusted free cash flow for H1 2024 of R1,324 million. There was a net increase (outflow) of R440 million in working capital compared to H1 2024, mainly attributable to an increase in inventory at the US PGM recycling operation. Included in the H1 2024 negative adjusted free cashflow were insurance proceeds received of R812 million related to the business interruption claim arising from the 2022 flood event.

The Reldan operation generated adjusted free cash flow of R533 million compared to adjusted free cash flow for H1 2024 of R101 million. The Reldan operation contribution to adjusted free cash flow for H1 2025 included two additional months compared to the four months for H1 2024.

The SA PGM operations incurred negative adjusted free cash flow of R716 million compared to adjusted free cash flow for H1 2024 of R848 million. There was a net increase (outflow) of R2,520 million in working capital compared to H1 2024, mainly attributable to build-up in inventory, primarily due to smelter rebuilds at Furnace 1 and 2 at Marikana and the secondary precious metal circuit at the Precious Metals Refinery.

The SA gold operations generated adjusted free cash flow of R667 million compared with negative adjusted free cash flow of R2,406 million in H1 2024, mainly due to impact of the higher gold price received during H1 2025. Also included in H1 2024 negative adjusted free cash flow were higher cash additions to property, plant and equipment of R285 million on the Burnstone project and R652 million at DRDGOLD. The managed SA gold operations adjusted free cash flow improved from a negative R823 million in H1 2024 to positive R70 million in H1 2025.

The European operations incurred negative adjusted free cash flow of R2,959 million compared to negative adjusted free cash flow for H1 2024 of R2,840 million, mainly attributable to capital expenditure on the Keliber lithium project of R2,864 million (H1 2024: R2,624 million).

The Century operation in Australia generated adjusted free cash flow of R279 million compared to negative adjusted free cash flow for H1 2024 of R668 million, due to the impact of increased production, higher zinc prices and reduced treatment charges compared to H1 2024 (due to the adverse weather experienced during Q1 2024).

1The US PGM operations’ underground production is converted to metric tonnes and kilograms, and financial performance is translated into rand. In addition to the US PGM operations’ underground production, the operation treats various recycling material, which is excluded from the statistics shown above

2Total SA PGM operations and Marikana excludes the production and costs associated with the purchase of concentrate (PoC) from third parties. For a reconciliation of the Operating cost, AISC and AIC excluding third party PoC, refer to “Reconciliation of operating cost excluding third party PoC for Total SA PGM operations and Marikana - Six Months” and “Reconciliation of AISC and AIC excluding third party PoC for Total SA PGM operations and Marikana – Six Months”

3The Platinum Group Metals (PGM) production in the SA operations is principally platinum, palladium, rhodium and gold, referred to as 4E (3PGM+Au) and measured at the concentrator, and in the US underground operations is principally platinum and palladium, referred to as 2E (2PGM)

4PGM sold includes the third party PoC ounces sold

5Total SA PGM operations’ unit cost benchmarks and capital expenditure exclude the financial results of Mimosa, which is equity accounted and excluded from revenue and cost of sales

6The average PGM basket price is the PGM revenue per 4E/2E ounce, prior to a purchase of concentrate adjustment

7Operating cost, All-in sustaining costs and All-in costs are not measures of performance under IFRS Accounting Standards and should not be considered in isolation or as substitutes for measures of financial performance prepared in accordance with IFRS Accounting Standards. See "Non-IFRS measures" for more information on the metrics presented by Sibanye-Stillwater. Because of its nature, All-in sustaining costs and All-in costs should not be considered as a representation of financial performance

8All-in cost excludes income tax, costs associated with merger and acquisition activities, working capital, impairments, financing costs, one-time severance charges and items needed to normalise earnings. For a reconciliation of cost of sales, before amortisation and depreciation to All-in cost, see “All-in costs - Six months”

9The US PGM operations’ operating cost, AISC and AIC for the six months ended 31 December 2024 and 30 June 2024 were adjusted to include Section 45X Advance Manufacturing Production Credits. During the six months ended 30 June 2025 the US PGM operations recognised R699 million (US$39 million) and R563 million (US$30 million) which relates to mining costs for the six months ended 31 December 2024 and 30 June 2024, respectively

10Rustenburg is now presented to include the underground production and costs for Kroondal for all metrics relating to the six months ended 31 December 2024 and 30 June 2024

Notes to the consolidated interim financial statements

1.    Basis of accounting and preparation
   

The consolidated interim financial statements are prepared in accordance with the requirements of the JSE Listings Requirements for interim results and the requirements of the Companies Act of South Africa. The JSE Listings Requirements require interim results to be prepared in accordance with framework concepts, and the measurement and recognition requirements of International Financial Reporting Standards Accounting Standards (IFRS Accounting Standards), as issued by the International Accounting Standards Board (IASB), the South African Institute of Chartered Accountants Financial Reporting Guides as issued by the Accounting Practices Committee and Financial Pronouncements as issued by the Financial Reporting Standards Council and to also, as a minimum, contain information required by IAS 34 Interim Financial Reporting. The accounting policies applied in the preparation of these consolidated interim financial statements are in terms of IFRS Accounting Standards and are consistent with those applied in the previous consolidated annual financial statements, included in the 31 December 2024 annual financial report.

The condensed consolidated interim income statement, and statements of other comprehensive income and cash flows for the six months ended 31 December 2024 were prepared by subtracting the condensed consolidated interim financial statements for the six months ended 30 June 2024 from the consolidated financial statements for the year ended 31 December 2024.

The convenience translation of the primary statements into US dollar is based on the average exchange rate for the period for the condensed consolidated interim income statement, statements of other comprehensive income and cash flows, and the period-end closing exchange rate for the condensed consolidated interim statement of financial position. Exchange differences on translation are accounted for in the condensed consolidated interim statement of other comprehensive income. This information is provided as supplementary information only.

6.    Impairments
   

The Group performed impairment testing for cash-generating units (CGUs) where indicators of impairment were present during the period ended 30 June 2025. The following impairments were recognised:

Total impairments	(9,666)	(1,549)	(7,624)

1 Mimosa's updated life-of-mine indicated above US dollar inflationary increases in working costs and capital costs, and includes a Zimbabwean beneficiation tax which resulted in a decrease in the expected future net cash flows from Mimosa. The lower value in use led to an after tax equity-accounted impairment of property, plant and equipment amounting to R535 million and the impairment of the investment in the equity-accounted investee of R64 million, before the impact of deferred tax (net an impairment of R461 million) (see note 8.3) (included in SA PGM on the segment report — see note 22). The weighted average PGM (4E) basket price, nominal discount rate and life-of-mine used in the Mimosa impairment assessment was R25,745/4Eoz, 20.67% and 8 years, respectively. The recoverable amount was determined as R2,208 million

Sibanye-Stillwater Operating and financial results | Six months ended 30 June 2025 30

The impairment of mining assets for the six months ended 30 June 2025 relates to the following classes of assets:

Figures in million - SA rand	Six months ended

	US PGM operations1	Keliber2	Other	Total

Total impairment	(4,230)	(5,344)	(28)	(9,602)

1 On 4 July 2025, the One Big Beautiful Bill Act was signed into US law and indicates a phase out and termination of Section 45X credits. Under the phase out and termination rules, any applicable critical mineral produced after 31 December 2030 is phased out with 25% over a period of 4 years commencing from 2031. This resulted in decreased future net cash flows from the US PGM operations and a reduction in value in use at 30 June 2025, and consequently to an impairment of property, plant and equipment amounting to R4,230 million

2 A decrease in the long-term forecasted lithium hydroxide price and an increased discount rate resulted in a decrease in the expected future net cash flows from Keliber and the value in use at 30 June 2025, and resulted in an impairment of property, plant and equipment amounting to R5,344 million. As part of the annual planning process, the Group continues to evaluate the timing of the ramp-up of the Keliber project, considering the potential recovery of the lithium market

The assumptions applied in the value in use impairment calculation as well as the recoverable amount for the below CGUs impacted by the impairments are set out below:

		Unaudited
		Jun 2025
		US PGM operations	Keliber
Average PGM (2E) basket price1	US$/2Eoz	1,118	—
Average lithium hydroxide price1	US$/t	—	17,972
Inflation rate2	%	2.1	2.0
Nominal discount rate3	%	10.56	11.19
Life-of-mine4,5	years	67	20
Recoverable amount	R' million	9,361	9,359

1 The weighted average commodity prices and exchange rate were derived by considering various bank and commodity broker consensus forecasts

2 The inflation rate is based on the expected forecast inflation rate for the geographic region which most affects the CGU's cash flows

3 The nominal discount rate is calculated as the weighted average cost of capital of the CGU

4 Periods longer than five years for inclusion in the impairment test are considered appropriate based on the nature of the operations since a formally approved life-of-mine plan is used to determine cash flows over the life of the mine based on the available reserves

5 In respect of Keliber, if the life-of-mine is not extended meaningfully, it is estimated that the concentrator and refinery will continue with external purchases of spodumene concentrate. A minimum of 7 years post life-of-mine were assumed for external purchase of spodumene concentrate

CGU impairment assumptions

The cash flows are based on the annual life-of-mine plans that takes into account the following:

•Proved and probable ore reserves of the CGU and conversion of resources where appropriate

•Revenue based on consensus forecast commodity prices, and operating costs

•Sustaining capital expenditure estimates over the life-of-mine plan

•Developmental capital expenditure, where applicable

Results of impairment assessments for the Group's CGUs

Other than the impairment to the US PGM operations, Keliber and Mimosa described above, no further significant impairment was identified for any of the Group's other CGUs for which impairment indicators were present. However, any delay in the ramp-up of Keliber may result in further impairment. A further 5% decrease in the average lithium hydroxide price or a 1% increase in the nominal discount rate, would result in a further R1,839 million or R1,413 million impairment, respectively. In addition, the Kloof CGU experienced logistical and operational disruptions, and abnormal seismicity in some areas which requires a re-evaluation of the Kloof mine's planned transition to higher volume, lower grade production. There is at risk of impairment of this CGU, should it be determined by the Group that the secondary reefs of Kloof cannot be safely and profitably accessed, however the final outcome can only be determined later in 2025 upon conclusion of the Group's evaluation and approval of an updated life of mine.

9.    Dividends
   

Dividend policy

The Group’s dividend policy is to return between 25% to 35% of normalised earnings to shareholders and after due consideration of future requirements the Board may declare a higher or lower dividend than determined according to this range. Normalised earnings is defined as earnings attributable to the owners of Sibanye-Stillwater, excluding gains and losses on financial instruments and foreign exchange differences, impairments and related compensation, gain/loss on disposal of property, plant and equipment, occupational healthcare expenses, restructuring costs, transactions costs, share-based payment expenses on B-BBEE transactions, gains on acquisitions, net other business development costs, share of results of equity-accounted investees, all after tax and after the impact of non-controlling interest, and changes in the estimated deferred tax rate.

Despite normalised earnings of R1,832 million (US$100 million) for the six months ended 30 June 2025, the Board has decided to maintain a more prudent and conservative approach considering the uncertain global economic and geo-political backdrop and resolved not to declare an interim dividend for 2025. A decision on an appropriate full year dividend for 2025, will instead be made by the Board of Directors after assessing the financial results for the year ending 31 December 2025 together with the prevailing operating context. No dividends were declared for 2024.

10.    Acquisitions
    

10.1 Reldan business combination (revised)

Sibanye-Stillwater successfully concluded the acquisition of the Reldan Group of Companies (Reldan) on 15 March 2024 by acquiring 100% of the shares and voting interest. Reldan is a recycling group which reprocesses various waste streams to recycle precious metals and is based in Pennsylvania, USA. In addition to Reldan's US operations, it has also established a presence in Mexico and India where it has forged strategic joint ventures with local partners. The acquisition complements the Group's US PGM recycling business in Montana and enhances its exposure to the circular economy. Reldan's financial results were consolidated from the effective date and the functional currency of Reldan is the US dollar.

The purchase price allocation (PPA) for the six months ended 30 June 2024, and year ended 31 December 2024, was prepared on a provisional basis in accordance with IFRS 3 Business Combinations (IFRS 3). During the 12 month measurement period commencing on the acquisition date, management provisionally revised the initial PPA previously recognised at 30 June 2024 and at 31 December 2024 due to new information obtained in accordance with IFRS 3. For the six months ended 30 June 2025, a final payment amounting to US$5 million (R96 million) was made to the sellers. This relates to a process completed by March 2025, whereby the sellers determined that an additional amount was due to them in terms of the purchase and sales agreement relating to their tax obligations.

The following table summarises the differences from amounts reported at 31 December 2024 due to the final revised PPA:

Figures in million - SA rand
	Unaudited
	Jun 2025
	As previous	As revised	Final payment
Fair value of identifiable net assets acquired	2,769	2,769	—
Consideration paid1	2,943	3,039	96
Fair value of NCI put liability2	109	109	—
Total consideration	3,052	3,148	96
Goodwill3,4,5	283	379	96

1 Cash consideration amounted to US$155.9 million (R2,920 million) paid in 2024. Due to new information obtained, cash consideration paid on the Reldan acquisition increased by US$5 million (R96 million) which was paid by 31 March 2025

2 Related to an NCI put option in respect of an intermediate Reldan holding company which holds an interest in the Indian joint venture operations, and may require the Group to purchase shares from the non-controlling shareholders of Reldan if exercised by the NCI. The put option can be exercised by the NCI between three and five years after the effective date at market price

3 The goodwill is attributable to the human capital and the premium paid for the synergies and benefits expected to be derived from enhancing the Group's recycling business across the US, Mexico and India

4 US tax legislation requires the purchase consideration to be allocated in order to determine future tax deduction. An amount of R1,188 million (US$63 million) is estimated to be deductible for tax purposes in the future

5 The calculation of goodwill, previously amounting to R283 million as revised at 31 December 2024, was finalised at 31 March 2025 based on new information obtained before the 12 months remeasurement period in terms of IFRS 3 was completed. The net adjustments based on the new information obtained resulted in additional goodwill of R96 million recognised in the prior year

1 The facility is undrawn at 30 June 2025 and at the date of this report

2 The R6.5 billion RCF is affected by the IBOR reform amendments to IFRS Accounting Standards, which came into effect on 1 January 2021. The R6.5 billion RCF is linked to the JIBAR for the foreseeable future and will transition to a new interest rate prior to the date on which the JIBAR will no longer be available for use. At 30 June 2025, there is no significant impact on the Group as a result of IBOR reform in respect of the R6.5 billion RCF and the Group will assess any potential impact when the facility is transitioned to a new rate in the future

3 Subsequent to 30 June 2025, all facility lenders have approved the first one-year extension resulting in the R6.5 billion RCF facility now maturing in August 2028

4 Other borrowings consist mainly of overnight facilities, working capital and overdraft borrowings facilities at Keliber, Century and Reldan

13.    Deferred revenue
    

On 19 December 2024 Sibanye-Stillwater entered into a US$500 million streaming agreement with Franco-Nevada in exchange for the sale of gold and platinum streams with reference to the Marikana, Kroondal, and Rustenburg operations. The last condition precedent was completed during February 2025, after which US$500 million (R9,215 million) upfront cash payment cash was received on 28 February 2025.

The key inputs and assumptions of the Franco-Nevada stream are as follows:

Key input	Estimate at period end	Further information
Estimated financing rate over life of the arrangement	8.76%	Rate applied at initial recognition to discount the platinum and gold stream, based on the expected gold and platinum to be delivered (including a determined number of resources).
Remaining life of stream	Marikana - 84 years<br><br>Rustenburg (excluding Kroondal) - 106 years<br><br>Kroondal - 23 years	The life of the stream is based on the approved life-of-mine for Marikana, Rustenburg (excluding Kroondal) and Kroondal plus a determined number of resources. The resources included were determined based on an evaluation of specific mining areas and possible projects at the mining areas.
Platinum entitlement percentage	1% of platinum production	1% of refined platinum ounces up to delivery of 48,000 ounces, after which it increases to 2.1% of refined platinum ounces up to delivery of 294,000 ounces in aggregate, after which the platinum stream is completed.
Gold entitlement percentage	1.1% of 4E PGM production	1.1% of 4E PGM ounces produced up to delivery of 87,500 ounces of refined gold, after which it decreases to 0.75% of 4E PGM ounces produced up to delivery of 237,000 ounces of refined gold in aggregate, after which it is 80% of refined gold production.
Monthly cash percentage	5%	The gold cash payment is 5% until 237,000 refined ounces is delivered after which it increases to 10%. Platinum is fixed at 5% over the life of the stream.
Allocation of stream between commodities over the expected life of the arrangement	Gold - 69%<br><br>Platinum - 31%	The US$500 million prepayment was allocated between gold and platinum at inception of the stream based on forward commodity consensus prices.
Covenants reduction date	31 October 2037	The covenant reduction date is the date on which the aggregate gold and platinum deliveries under the terms of the stream exceeds US$600 million. Once the covenant reduction date is reached, certain limitations on incurring debt and encumbrances on assets fall away and instances where the production payments are limited to a nominal fixed amount per ounce no longer apply.

The table below summarises the Franco-Nevada stream:

R625 million revenue was recognised related to the Century deferred proceeds (R178 million for the six months ended 31 December 2024 and R484 million for the six months ended 30 June 2024)

14.    Fair value of financial assets and financial liabilities, and risk management
    

14.1 Measurement of fair value

The Group uses the following hierarchy for determining and disclosing the fair value of financial instruments:

•Level 1: unadjusted quoted prices in active markets for identical assets or liabilities

•Level 2: inputs other than quoted prices in level 1 that are observable for the asset or liability, either directly (as prices) or indirectly (derived from prices)

•Level 3: inputs for the asset or liability that are not based on observable market data (unobservable inputs)

The following table sets out the Group’s significant financial instruments measured at fair value by level within the fair value hierarchy:

1 Environmental rehabilitation obligation funds presented in the condensed consolidated interim statement of financial position, comprise a fixed income portfolio of bonds, rehabilitation policies, investment in a cell captive as well as fixed and notice deposits. The environmental rehabilitation obligation funds, not measured at amortised cost, are stated at fair value based on the nature of the fund’s investments. For investments measured at fair value classified as level 2, the fair value is determined through valuation techniques that include inputs other than quoted prices in level 1 that are observable for the asset, either directly or indirectly. The valuation techniques applied make reference to the net asset value of the underlying assets in the relevant policy or cell captive, adjusted for any entity-specific risk. These underlying assets comprise predominantly money-market and similar highly liquid investments for which the carrying values approximate fair value

2 The fair value for trade receivables measured at fair value through profit or loss is determined based on ruling market prices, volatilities and interest rates

3 The fair values of listed investments are based on the quoted prices available from the relevant stock exchanges. The carrying amounts of other short-term investment products with short maturity dates approximate fair value. The fair values of non-listed investments are determined through valuation techniques that include inputs that are not based on observable market data. These inputs include price/book ratios as well as marketability and minority shareholding discounts which are impacted by the size of the shareholding. The level 3 balance consists primarily of an investment in Verkor, which is valued based on a share subscription price determined by market participants at acquisition and since Verkor is a pre-revenue operation still in development, the subscription price is considered a reasonable approximation of fair value. The difference between other investments in the statement of financial position and the table above, relates to investments measured at amortised cost, with carrying amounts that approximate fair values

4 The fair value of the gold hedge is determined using a Monte Carlo simulation model based on market forward prices, volatilities and interest rates. The fair value of the zinc hedge is determined by using a Monte Carlo simulation model based on historical zinc market spot and forward prices, volatilities and interest rates and the relevant foreign exchange forward curve data

5 The fair value of the contingent consideration relating to the Kroondal acquisition was derived from discounted cash flow models. These models used several key assumptions, including estimates of future production volumes, PGM basket prices, operating costs, capital expenditure and a market related discount rate

6 The fair value of the Reldan metals borrowing liability at the reporting date was calculated based on the spot prices of the relevant metals owed to the financial institution

1 The fair value is based on the quoted market prices of the notes

2 The fair value of the Burnstone Debt has been derived from discounted cash flow models. These models use several key assumptions, including estimates of future sales volumes, gold prices, operating costs, capital expenditure and discount rate. The Burnstone long-term gold price at 30 June 2025 and 31 December 2024 was R1,189,493/kg (30 June 2024: R1,012,625/kg) and the discount rate applied was 9.77% (31 December 2024: 9.55%, 30 June 2024: 10.01%). The fair value estimate is sensitive to changes in the key assumptions, for example, increases in the market related discount rate would decrease the fair value if all other inputs remain unchanged. The extent of the fair value changes would depend on how inputs change in relation to each other

3 The fair value at 30 June 2025 represents the quoted price of the US$ Convertible Bond

4 The fair value was calculated by applying a market-related discount rate to expected future cash flows available for dividends

14.2 Risk management activities

Liquidity risk: working capital and going concern assessment

For the six months ended 30 June 2025, the Group incurred a loss of R3,906 million (31 December 2024: realised a profit of R1,291 million and 30 June 2024: incurred a loss of R7,001 million). As at 30 June 2025 the Group’s current assets exceeded its current liabilities by R39,476 million (31 December 2024: R27,458 million) and the Group’s total assets exceeded its total liabilities by R44,345 million (31 December 2024: R48,289 million). During the six months ended 30 June 2025 the Group generated cash from operating activities of R13,177 million (31 December 2024: generated cash of R6,416 million and 30 June 2024: R3,697 million).

The Group has committed undrawn debt facilities of R24,202 million at 30 June 2025 (31 December 2024: R26,743 million) and cash balances of R21,012 million (31 December 2024: R16,049 million). The Group’s leverage ratio (net debt/(cash) to adjusted EBITDA) as at 30 June 2025 was 0.89:1 (31 December 2024 was 1.79:1 and 30 June 2024 was 1.43:1) and its interest coverage ratio (adjusted EBITDA to net finance charges) was 19.9:1 (31 December 2024 was 66.0:1 and 30 June 2024 was 1,273.0:1). Both considerably better than the uplifted maximum permitted leverage ratio of at most 3.5:1 and minimum required interest coverage ratio of 3.0:1, calculated on a quarterly basis, as required under the US$1 billion RCF and the R6.5 billion RCF. The maximum permitted leverage ratio up to 30 June 2025 was 3.5:1, up to 31 December 2025 is 3.0:1 and thereafter 2.5:1. The maximum required interest coverage ratio up to 30 June 2025 was 3.0:1, up to 31 December 2025 3.5:1 and 4.0:1 thereafter. At the date of approving these consolidated interim financial statements for issue, the US$1 billion RCF is undrawn, the R6.5 billion RCF had R3.5 billion available and there were no significant events which had a significant negative impact on the Group’s strong liquidity position.

Management believes that the cash forecasted to be generated by operations, cash on hand, the committed unutilised debt facilities as well as additional funding opportunities will enable the Group to continue to meet its obligations as they fall due for a period of at least eighteen months after the reporting date. The consolidated interim financial statements for the six months ended 30 June 2025 have therefore been prepared on a going concern basis.

15.    Contingent liabilities/assets
    

15.1 Notice from Appian Capital to commence legal proceedings

On 26 October 2021, Sibanye-Stillwater entered into share purchase agreements (the Atlantic Nickel SPA and the MVV SPA, respectively (together, the SPAs)) to acquire the Santa Rita nickel mine and Serrote copper mine (together, the Assets) from affiliates of Appian Capital Advisory LLP (Appian). On 9 November 2021, a geotechnical event occurred at the Santa Rita Mine. After becoming aware of the geotechnical event, Sibanye-Stillwater assessed the event and its effect and concluded that the event was and was reasonably expected to be material and adverse to the business, financial condition, results of operations, the properties, assets, liabilities or operations of the Santa Rita Mine. Sibanye-Stillwater therefore considered that a condition to closing under the Atlantic Nickel SPA – namely, that no material adverse effect had occurred since the date of the SPA – had not been satisfied. Accordingly, Sibanye-Stillwater gave notice of termination of the Atlantic Nickel SPA on 24 January 2022. As the MVV SPA was conditional on the closing of the Atlantic Nickel SPA, Sibanye-Stillwater also gave notice of termination of the MVV SPA on the same day.

On 3 February 2022, Appian sent a letter to Sibanye-Stillwater indicating that it was terminating the SPAs by reason of Sibanye-Stillwater’s wrongful repudiation and/or renunciation of the SPAs. On 16 February 2022, Appian served a claim notice to Sibanye-Stillwater, and, on 27 May 2022, it initiated legal proceedings before the High Court of England and Wales (the Court).

Sibanye-Stillwater Operating and financial results | Six months ended 30 June 2025 38

The first phase of the proceedings related to whether the geotechnical event was, or could reasonably be expected to be, material and adverse (the Liability Trial). In a judgment handed down on 10 October 2024, the Court ruled that the geotechnical event was not, and was not reasonably expected to be, material and adverse, such that Sibanye-Stillwater was not entitled to terminate the SPAs. However, the Court dismissed Appian's claim of wilful misconduct, ruling that the management of Sibanye-Stillwater genuinely believed that it was entitled to terminate the SPAs in what they perceived as the best interests of Sibanye-Stillwater.

The second phase of the proceedings is scheduled to proceed to a trial in November 2025 (the Quantum Trial), at which the Court will determine the damages (if any) that Sibanye-Stillwater may be required to pay to Appian. The parties disagree as to how Appian's recoverable losses should be calculated. The basis for calculating damages will largely depend on the Court's view as to the appropriate date on which to value the Assets and the correct basis on which to calculate interest. The appropriate date for valuing the Assets will depend on the Court's view as to whether and, if so, when Appian could have sold the Assets at a fair price to an alternative buyer. That valuation date will, in turn, inform the appropriate basis for valuing the Assets. This is a matter for expert evidence, the process for which is ongoing at the reporting date. However, relevant factors for valuing the Assets are likely to include whether, and to what extent, various offers received by Appian for the Assets (including, in respect of MVV, the sale completed between Appian and Baiyin in April 2025), and other factors such as commodity price volatility, should be taken into account. The appropriate basis on which to calculate interest will depend on the Court's view as to the principal amount on which Appian may claim interest, and the appropriate interest rate to be applied. This will also be the subject of expert evidence.

Based on the parties' current expert evidence, and depending on the valuation methodology adopted, Appian's recoverable loss (including interest) may be between US$nil and US$721 million. This is subject to any amendments to the parties' pleadings between the reporting date and the Quantum Trial, as well as further evidence, including expert valuation reports, to be exchanged between the parties ahead of the Quantum Trial.

It is not reasonably possible to assign probabilities to the possible loss scenarios to be determined at the Quantum Trial, as at the reporting date, as there is significant uncertainty in predicting the likely result of the Quantum Trial. Since the range of potential outcomes is wide and the actual outcome can be materially different to any current estimate, management concluded that the potential obligation, if any, cannot be reliably measured at the reporting date. Judgment on the Quantum Trial is expected to follow in Q1 2026.

16.    Section 45X Advance Manufacturing Production Credit
    

The US PGM operations qualifies for an Advanced Manufacturing Production credit amount, equal to 10 percent of the costs incurred with respect to production of certain qualifying critical minerals under the Inflation Reduction Act (IRA) in the US, more specifically the Section 45X Advanced Manufacturing Production (“AMP”) credit. Due to the fact that the US PGM operations outsources the purification of platinum, palladium and rhodium to an unrelated third party refinery, it is required that the US PGM operations must enter into an agreement with the third party that identifies the US PGM operations as the sole party that may claim the credit and both the third party and the US PGM operations signs a certification statement reflecting this agreement.

During the six months ended 30 June 2025, the certification statements relating to the 31 December 2023 and 31 December 2024 financial years were signed by the US PGM operations and the third party refinery. The refining agreement was also subsequently amended to address the certification for the remainder of the contract period. Accordingly, R2,472 million (US$139 million) and R1,931 million (US$109 million) were recognised as income during the six months ended 30 June 2025, but in respect of the 2023 and 2024 Section 45X credits, respectively. Section 45X credit income amounting to R649 million (US$36 million) was recognised in respect of the six months ended 30 June 2025. The amounts were recognised as a credit to cost of sales. The related receivable is included in other receivables on the consolidated interim statement of financial position.

The Section 45X credits for 2023 amounted to R1,245 million (US$70 million) and R1,227 million (US$69 million) for the underground mining operations and recycling operations, respectively, and the Section 45X credits for 2024 amounted to R1,220 million (US$69 million) and R711 million (US$40 million) for the underground mining operations and recycling operations, respectively. The Section 45X credits for the six months ended 30 June 2025 amounted to R360 million (US$20 million) and R289 million (US$16 million) for the underground operations and recycling operations, respectively.

17.    Assets and associated liabilities classified as held for sale
    

During the six months ended 30 June 2025, following the Group's decision to withdraw from the Rhyolite Ridge joint venture agreement, it was decided to sell its investment in ioneer Limited (ioneer). The Group held 145,862,742 shares in ioneer representing 6.19% of their share capital. At 30 June 2025, the investment (R164 million) was classified as held for sale in accordance with the requirements of IFRS 5 Non-current Assets Held for Sale and Discontinued Operations (IFRS 5). The sale of ioneer was effective subsequent to 30 June 2025.

During the six months ended 30 June 2025, DRDGOLD decided to sell its 50.25% share in Stellar, a renewable energy company developing a solar plant in Limpopo, South Africa. The decision was based on DRDGOLD's decision to focus on its core operating activities. At 30 June 2025, DRDGOLD's investment in Stellar was classified as held for sale in accordance with the requirements of IFRS 5. Property, plant and equipment and capital prepayments of R105 million and other net assets of R6 million is included in assets held for sale at 30 June 2025.

The transaction to sell the Beatrix 4 shaft, which forms part of the Beatrix gold operations and includes the Beisa uranium project, to Neo Energy Metals Plc. (Neo Energy) for a total transaction consideration of R500 million, comprising R250 million in cash and R250 million in newly issued shares in Neo Energy was still subject to certain outstanding conditions precedent at the reporting date. The assets and liabilities associated with the transaction remained classified as held for sale in accordance with the requirements of IFRS 5. Neo Energy will assume responsibility for all Beatrix 4 shaft rehabilitation and environmental liabilities, which amounts to a carrying value of R470 million at 30 June 2025. Property, plant and equipment of R30 million relating to the Beatrix 4 shaft disposal is included in assets held for sale at 30 June 2025.

The assets presented as assets held for sale were measured at the lower of the carrying values and fair value less cost to sell.

1The adjusted earnings before interest, taxes, depreciation and amortisation (EBITDA) calculation is based on the definitions included in the facility agreements for compliance with the debt covenant formula, except for impact of new accounting standards, project finance subsidiaries (Burnstone) and acquisitions, where the facility agreements allow the results from the acquired operations to be annualised. Adjusted EBITDA, as defined and reconciled above, is not a measure of performance under IFRS Accounting Standards. As a result, it should not be considered in isolation or as alternatives to any other measure of financial performance and liquidity presented in accordance with IFRS Accounting Standards

1Corporate and reconciling items represent the items to reconcile segment data to consolidated financial statement totals, such as intercompany eliminations and share of results of equity-accounted investees after tax. This does not represent a separate segment as it does not generate revenue

2Included in cost of sales, before amortisation and depreciation is total write-down of inventory to net realisable value amounting to R1,199 million. This write-down mainly relates to PGM in process and PGM finished goods of R949 million and R250 million, respectively, relating to the US PGM operations

1Corporate and reconciling items represent the items to reconcile segment data to consolidated financial statement totals, such as intercompany eliminations and share of results of equity-accounted investees after tax. This does not represent a separate segment as it does not generate revenue

2Included in cost of sales, before amortisation and depreciation is total write-down of inventory to net realisable value amounting to R2,710 million. This write-down mainly relates to PGM in process and PGM finished goods of R2,222 million and R428 million, respectively, of which R1,857 million, R487 million, R264 million and R42 million, relates to the US PGM operations, Rustenburg, Kroondal and Marikana, respectively, as a result of the lower commodity price environment

Average exchange rate for the six months ended 30 June 2025, 31 December 2024 and 30 June 2024 was R18.39/US$, R17.92/US$ and R18.72/US$, respectively

Figures may not add as they are rounded independently

1The US PGM operations’ underground production is converted to metric tonnes and kilograms, and financial performance is translated into SA rand. In addition to the US PGM operations’ underground production, the operation processes various recycling material, which is excluded from the 2E PGM production, All-in sustaining cost and All-in cost statistics shown. The US Reldan operations cost and performance are also excluded from the above table

2The Total SA PGM operations and Marikana includes the production and costs associated with the purchase of concentrate (PoC) from third parties. For a reconciliation of the Operating cost, AISC and AIC excluding third party PoC, refer to “Reconciliation of operating cost excluding third party PoC for Total SA PGM operations and Marikana - Six Months” and “Reconciliation of AISC and AIC excluding third party PoC for Total SA PGM operations and Marikana – Six Months”

3Cost of sales, before amortisation and depreciation includes all mining and processing costs, third party refining costs, corporate general and administrative costs, and permitting costs

4Share-based payments are calculated based on the fair value at grant date and do not include the adjustment of the cash-settled share-based payment obligation to the reporting date fair value

5Rehabilitation includes the interest charge related to the environmental rehabilitation obligation and the amortisation of the related capitalised rehabilitation costs. The interest charge related to the environmental rehabilitation obligation and the amortisation of the capitalised rehabilitation costs reflect the periodic costs of rehabilitation associated with current PGM production

Sibanye-Stillwater Operating and financial results | Six months ended 30 June 2025 46

6All-in cost excludes income tax, costs associated with merger and acquisition activities, working capital, impairments, financing costs, one-time severance charges and items needed to normalise earnings. All-in cost is made up of All-in sustaining cost, being the cost to sustain current operations, given as a sub-total in the All-in cost calculation, together with corporate and major capital expenditure associated with growth. All-in sustaining cost per ounce and All-in cost per ounce are calculated by dividing the All-in sustaining cost and All-in cost, respectively, in a period by the total 4E/2E PGM produced (excluding Mimosa) in the same period

7The Inflation Reduction Act Section 45X Advanced Manufacturing Production Credit provides credits to the US PGM operations equal to 10% of production costs incurred for critical minerals produced and sold after December 31, 2022. During the six months ended 30 June 2025 the US PGM operations recognised R699 million (US$39 million) and R563 million (US$30 million) which relates to mining costs for the six months ended 31 December 2024 and 30 June 2024, respectively. Although these amounts were recognised as a credit against the 30 June 2025 cost of sales, management believes that the cost of sales for the period ended 30 June 2025 should be adjusted with the 2023 and 2024 credits against the period when the mining costs were accrued. It is expected that, because the required certification requirements were addressed in June 2025, the recognition of the credits will now match the related mining cost accruals. Accordingly, total All-in-sustaining costs and total All-in-costs were adjusted to reflect the appropriate amounts which relates to the periods presented above.

Average exchange rate for the six months ended 30 June 2025, 31 December 2024 and 30 June 2024 was R18.39/US$, R17.92/US$ and R18.72, respectively

Figures may not add as they are rounded independently

1    The US PGM operations’ underground production is converted to metric tonnes and kilograms, and performance is translated into rand. In addition to the US PGM operations’

underground production, the operation treats various recycling material which is excluded from the statistics shown above. The US Reldan operations cost and performance are also excluded from the above table

2    Total SA PGM operations exclude the results of Mimosa (financial and production results), which is equity accounted

3    Cost of sales, before amortisation and depreciation for Total SA PGM operations, Rustenburg (including Kroondal), Marikana and Platinum Mile includes the Chrome cost of sales which is excluded for operating unit cost calculation purposes as Chrome production is excluded from the concentrate production

4    For a reconciliation of the production excluding Mimosa and third party PoC, refer to “Reconciliation of operating cost excluding third party PoC for Total SA PGM operations and Marikana - Six months”

5    Operating cost is the average cost of production and operating cost per tonne is calculated by dividing the cost of sales, before amortisation and depreciation, adjusted for change in inventory, less chrome- and PoC cost of sales in a period by the tonnes milled/treated in the same period, and operating cost per ounce is calculated by dividing the cost of sales, before amortisation and depreciation, adjusted for change in inventory, less chrome- and PoC cost of sales in a period, by the PGM produced in the same period

6 The US PGM operations’ operating cost for the six months ended 31 December 2024 and 30 June 2024 were adjusted to include the Section 45X Advance Manufacturing Production Credits. During the six months ended 30 June 2025 the US PGM operations recognised R699 million (US$39 million) and R563 million (US$30 million)which relates to mining costs for the six months ended 31 December 2024 and 30 June 2024, respectively
