Harmony Gold Mining Company Limited | Interim results for the six-month period ended 31 December 2025 1 MESSAGE FROM THE CHIEF EXECUTIVE OFFICER OVERVIEW During the period under review, we further reinforced Harmony’s position as a higher‑quality, lower‑risk global producer of gold and copper. Our strategy remains anchored in safe, predictable and profitable production that delivers resilient cash flows and supports disciplined, long‑term growth. Safety remains our first value. We are encouraged by the continued improvement in our lost‑time injury frequency rate, which has remained below 5.00 per million hours worked, for three consecutive quarters. This reflects strengthened ownership across the business. Our commitment to achieving zero harm remains non-negotiable. Gold remains core to Harmony. Expanding into copper is an intentional step to enhance portfolio quality and long‑term durability. Our capital allocation framework is measured, disciplined and value‑focused, to enhance operational consistency, strengthen margins and support predictable cash flows. Even in an elevated commodity price environment, capital discipline remains paramount. We deploy capital prudently on a risk‑adjusted basis across safety, sustaining our orebodies, greenfield projects, brownfield expansions and shareholder returns – ensuring we create long-term value through commodity price cycles. Our strengthened cash generation has enabled us to revise our dividend policy to ensure that up to 50% of our net free cash is returned to investors, reflecting our commitment to delivering tangible, consistent and attractive cash returns. Our approach ensures that investors benefit today through sustainable and enhanced dividends, while also participating in the long‑term value we are creating across our portfolio. Maintaining a balance sheet well below our 1x net debt/EBITDA threshold, positions us to both fund future growth and continue rewarding shareholders. Operationally, we remain on track to meet our full‑year production, cost and grade guidance and the exceptional gold price environment has further supported another strong financial performance. This combination of operational discipline and favourable market conditions has translated into robust cash generation. Based on current projects, we expect to produce approximately 100 000 tonnes of copper per annum within the next three years, once the Eva Copper Project is completed. This will establish Harmony as a world‑class gold producer with a meaningful copper footprint. Against this backdrop, I am pleased to report that Harmony has once again delivered solid operational and financial results for H1FY26, demonstrating the strength of our strategy and the quality of our people.

MESSAGE FROM THE CHIEF EXECUTIVE OFFICER continued Harmony Gold Mining Company Limited | Interim results for the six-month period ended 31 December 2025 2 RESPONSIBLE STEWARDSHIP Safety: Proactive strategy continues to deliver improvements Nothing matters more than ensuring every person returns home safely, every day. Our people are our most important assets and we remain unwavering in our commitment to zero loss of life. Tragically we lost one colleague in the second quarter of the financial year. We remember and honour the life of Mr Markus Bekker, electrician at Mponeng, 26 October 2025 (Q2FY26). Through our Thibakotsi’s humanistic culture transformation we are embedding personal ownership across the organisation. This is supported by our Accountability Model, Risk Response Protocol and disciplined learning from incidents. Our proactive focus on leading indicators, continues to drive quarter‑on‑quarter progress across our key safety measures. Performance and scorecard remuneration has been amended and is now linked to both leading and lagging indicators. Leading indicators include Workplace Hazard Ratings and Loss-of-life Critical Control Checks while lagging indicators include LTIFR. This year we made progress, delivering a loss-of-life free first quarter and all major indicators improving year on year – evidence of the discipline, consistency and accountability across the organisation. Our safety non‑negotiables are clear and constant: golden control compliance, effective management and supervisory routines, and life‑saving behaviours – everywhere, every shift. This is how we deliver safe, predictable production and live our pillar of Responsible Stewardship until zero harm is a reality for every person at Harmony. Indicator per million hours worked H1FY26 H1FY25 LTIFR1 4.23 5.52 RIFR2 2.82 3.38 LLIFR3 0.02 0.02 1. Lost time injury frequency rate 2. Reportable injury frequency rate 3. Loss of life injury frequency rate Embedded sustainability Sustainability is embedded in how we run the business and is integral to holistic risk management. We are advancing our science‑based pathway to net‑zero by 2045, with the 100 MW Moab Khotsong PV plant scheduled to begin phased commissioning in April 2026. This progress is supported by a growing pipeline of renewable‑energy initiatives that strengthen operational resilience by reducing emissions exposure and mitigating power‑price volatility. Harmony’s 2025 CDP results highlight our leadership in water stewardship, earning a Leadership score of A- in Water Security and a Management score of B in Climate Change, both improved from prior years. The 2025 CDP scores further reflect a mature, well-governed and transparent approach to environmental management, further demonstrating our commitment to sustainability, while also positioning the company as a benchmark for responsible mining within the gold sector. Our community programmes will continue to grow alongside our rehabilitation and environmental stewardship work. This integrated approach of combining climate action, operational discipline and meaningful social investment, ensures we remain responsible custodians of the assets and communities entrusted to us, while building a more resilient, competitive and future‑focused Harmony. CAPITAL ALLOCATION ANCHORED IN DISCIPLINED, LONG‑TERM VALUE CREATION Revised dividend policy returns more of our net free cash* to shareholders After careful consideration of our capital requirements, capital structure, through-the-cycle macroeconomic conditions and current strong cash flow generation, we are pleased to announce that we have revised our dividend policy to provide shareholders with enhanced upside participation. Harmony has amended its dividend policy to allow for up to 50% of net free cash* to be returned to shareholders, subject to the discretion of the board and net debt to EBITDA (leverage) levels. The revised policy now includes an improved base dividend, which has been increased from 20% to 30% of net free cash*. In addition, an upside dividend may be paid, based on leverage levels. When leverage is equal to or above 0.5x and below 1x, only a base dividend of 30% of net free cash* is payable. As leverage improves, the board may at its sole discretion consider an upside dividend of up to 20% of net free cash*. In-line with our new dividend policy, we are pleased to announce an interim dividend of 530 SA cents (32 US cents**) per share for this reporting period, resulting in a rolling 12-month dividend yield of 2.2% based off the closing JSE share price of R318.11 on 6 March 2026. It also represents a total payout of 43% of net cash*. The total dividend payout for this reporting period is a record R3 383 million (US$204 million). * Net free cash is defined as operating free cash flow after capital, interest, tax, corporate and other expenses. ** The dividend was converted using a closing exchange rate of R16.55/US$1 at 6 March 2026. Balance sheet strength and flexibility maintained We have maintained a healthy balance sheet which is in a net debt position of R5 544 million (US$335 million) after the acquisition of MAC Copper. EBITDA for the reporting period increased by 39% to R18 004 million (US$1 037 million) in H1FY26 from R12 924 million (US$721 million) in H1FY25. Our annualised net debt/EBITDA was 0.18 times as at 31 December 2025 and comfortably below the 1 times internal threshold. At current levels we expect to be back in a net cash position by the end of the financial year. We had R14 819 million (US$895 million) available in cash and undrawn facilities as at 31 December 2025. We are therefore well-positioned to continue funding all our operational needs alongside our various growth projects while paying a consistent and enhanced dividend. We are actively assessing our capital structure to maintain an efficient balance sheet that is appropriately matched to both our funding needs and the strength of our cash‑flow generation. ›‹

MESSAGE FROM THE CHIEF EXECUTIVE OFFICER continued Harmony Gold Mining Company Limited | Interim results for the six-month period ended 31 December 2025 3 Investing in our future: allocating capital towards quality orebodies Group capital expenditure (excluding Eva Copper) for H1FY26 increased by 35% to R6 391 million (US$369 million) from R4 725 million (US$263 million) in H1FY25. In addition to higher sustaining capital, much of this was allocated to advancing our major projects currently in execution. Our planned capital expenditure is accelerating the shift in Harmony’s portfolio towards a more profitable company with improved valuations. This is transformational capital designed to lower risk, lift margins and increase exposure to higher‑quality, gold and copper production – and not simply sustain the status quo. By investing now in quality, longer‑life orebodies, we materially strengthen future cash flow potential and position Harmony to deliver structurally higher returns as we move down the global cost curve. Within three to five years, these investments will reshape the company’s fundamentals and unlock a far more competitive, resilient and value‑accretive portfolio. Project execution excellence is therefore a non‑negotiable component of our operating model. Further information on our expansion projects and acquisition can be found under the International section below. Our Moab Khotsong and Mponeng extension projects are progressing well while the Kareerand extension project at Mine Waste Solutions and decline project at Target 1 are both complete. Other brownfield projects underway include the Doornkop extension and the life-of mine extension at Hidden Valley in Papua New Guinea. Studies are underway to convert additional Resources to Reserves through the Free State and West Wits Reclamation projects. Revenue, earnings growth and shareholder returns The higher gold price continued to translate directly into improved group revenue and operating profit. For the period, operating profit increased by 61% to R16 107 million (US$930 million) from R10 003 million (US$559 million) in H1FY25. Operating profit was partially impacted by derivative losses of R1 039 million (US$60 million), mainly relating to the silver derivative loss at Hidden Valley. Group revenue increased by 20% to R44 400 million (US$2 557 million) from R37 141 million (US$2 071 million). This increase was mainly due to the higher average gold price received, which increased by 36% to R1 909 849/kg (US$3 421/oz) from R1 405 020/kg (US$2 437/oz) in H1FY25. Strong gold revenue for the reporting period was partially offset by a realised hedge loss of R4 483 million (US$258 million). Silver revenue decreased by 27% to R740 million (US$43 million) from R1 008 million (US$56 million), due to a 52% reduction in Hidden Valley silver production. This was partially offset by a 46% increase in the average silver price received to R25 282/kg (US$45.12/oz). Uranium revenue decreased by 47% to R240 million (US$14 million) from R449 million (US$25 million), mainly due to a 44% decrease in uranium sold as a result of shipping delays. Uranium production at Moab Khotsong declined by 13% to 235 414lb, while prices remained broadly flat at US$82.08/lb. Copper revenue from the CSA mine totalled R417 million (US$24 million) in the first two months since acquisition. This marks Harmony’s maiden entry into copper production as we delivered 3 913 tonnes, establishing a new chapter in our history and positioning Harmony to benefit from long‑term demand for future‑facing metals. The variance between operating profit and earnings for the period was mostly driven by transitionary, non‑cash or acquisition‑related items, as well as higher current taxation. These are associated with growth, profitability and the investment in long‑life, value‑accretive assets. Harmony’s underlying fundamentals remain strong, and the increase in operating profit reflects the health of the core business. The key items impacting earnings for the period were: • acquisition‑related costs: R1 379 million (US$79 million) from the MAC Copper transaction, mainly stamp duty • non‑cash fair‑value adjustments: R861 million (US$50 million) on CSA’s copper and silver streaming arrangements. These do not affect operating performance (refer to note 15 in the financial statements) • increased financing costs: R708 million (US$41 million), including R188 million (US$11 million) related to the bridge facility used for the acquisition • higher current tax expense: up by 86% to R3 585 million (US$206 million) from R1 928 million (US$107 million), mainly due to higher mining taxes driven by significantly improved profitability. As result of the above, basic earnings per share increased by 24% to 1 563 SA cents (90 US cents) from 1 265 SA cents (71 US cents). Headline earnings per share rose by 13% to 1 431 SA cents (82 US cents) from 1 270 SA cents (71 US cents). The Harmony share price performed well over the 12-month period ending 31 December 2025. On the JSE, the share price increased by 124%, closing at R337.08. On the NYSE, the share price rose by 142%, closing at $19.90. Derivatives and hedging We continue to apply our hedging strategy with discipline because we believe it is a prudent risk management tool given our project pipeline and higher capital expenditure planned over the next three years. We do not speculate on the gold price and hedging allows us to lock in margins, protect cash flows and reduce the impact of potential adverse commodity and currency movements. This in part allows us to meet our capital and growth commitments through the cycle. Hedging helps safeguard the business, protect returns and maintain financial flexibility, so that we can continue delivering sustainable value across commodity cycles. The record gold prices continue providing an excellent opportunity to replace maturing hedges with new ones as they expire, locking in higher margins in line with our hedging policy. The gold hedge book was maintained at between 10% and 30% of production over a rolling 36-month period. The average floor and ceiling price on our rand gold zero cost collar book of 552 000oz stood at R1 922 834/kg and R2 169 635/kg respectively. The longer dated maturities reflect higher protection levels being locked in off the recently higher spot gold price. The increase in derivative losses is mainly driven by the significant rise in the silver spot price during the period, which moved further above the average locked‑in cap prices of the outstanding silver collar contracts. This resulted in a loss of R1.1 billion (US$63 million), partially offset by the realised foreign exchange derivative gain of R236 million (US$14 million). Refer to notes 2 and 9 in the financial statements for details on the derivative programme. ›‹

MESSAGE FROM THE CHIEF EXECUTIVE OFFICER continued Harmony Gold Mining Company Limited | Interim results for the six-month period ended 31 December 2025 4 Cash flow and margins Group adjusted free cash flows (cash generated from operating activities adjusted for capital expenditure) increased by 4%, to R5 965 million (US$344 million) from the previous half-year record of R5 729 million (US$320 million) set in H1FY25. Group adjusted free cash flow margins decreased to 14% from 16% in the previous reporting period. OPERATIONAL EXCELLENCE: OVER A DECADE OF CONSISTENCY THROUGH SAFE, PREDICTABLE PRODUCTION Safety, operational predictability and mining discipline remains central to delivering on our plans. Consistent control of key quality metrics including maintaining optimal stoping widths, driving sweeping compliance and reducing off‑reef mining ensures that every face contributes quality tonnes at the right grade. At the same time, strengthening mining flexibility through well‑sequenced development, improving productivity across crews and enhancing critical infrastructure all help reduce variability and create the resilience needed to meet plan. A safe mine is a productive mine and having embedded these disciplines shift after shift, we are delivering the tonnes to ensure we protect margins and support the sustainable delivery of long‑term value. Production and grade Group gold production for the period decreased by 9% to 22 522kg (724 099oz) from 24 816kg (797 854oz) in H1FY25. As previously disclosed in the 3 February 2026 operational update, this was marginally below plan due to lower metallurgical recoveries, tectonic-related mill motor failure at Hidden Valley and a deferment of the final Hidden Valley shipment to January 2026. Production was further impacted by the industry‑wide cyanide shortage in South Africa following Sasol’s force majeure. Despite these temporary headwinds, we remain on track to meet full‑year guidance and deliver as planned. Underground recovered grades decreased by 11% to 5.72g/t from 6.40g/t in the previous reporting period. Underground face grades remain in line with plan while recoveries have normalised. Disciplined cost control Harmony is a predominantly rand-cost producer and currency volatility remains part of our reality. What matters is controlling what we can and how we respond to external factors beyond our control. Cost discipline has always been at the heart of Harmony’s success, and in H1FY26 we again kept our unit cost increases predictable and within guidance despite inflation, higher royalties and a volatile macro backdrop. The rand strengthened by 3% to an average of R17.36/US$1 in H1FY26 from R17.94/US$1 in the comparable reporting period, which negatively affected the translation of our costs into US dollars. We do not lower cut‑off grades simply because the gold price is strong as this drives costs up in the long term. Meticulous planning, stringent cost controls and quality mining is crucial to protect margins. In line with plan, total cash operating costs net of by-product credits in H1FY26 increased by 12% to R22 552 million (US$1 299 million) from R20 195 million (US$1 126 million) in H1FY25. This was mainly due to the above-inflation tariff electricity increases in South Africa which resulted in a 14% increase in total electricity costs. Royalties increased by 60% or R490 million (US$30 million) due to higher revenue and profitability. Total labour costs, which makes up over half of our cash operating costs, remain predictable and controlled due to the five-year wage agreement that is in place in South Africa until June 2029. Labour costs increased by 6%, below our planned mining inflation. The newly acquired CSA copper mine contributed R378 million (US$22 million) to our costs. Excluding CSA, total cash operating costs increased by 10% to R22 174 million (US$1 277 million). On a per unit basis (gold operations only): • Cash operating costs increased by 21% to R984 549/kg (US$1 764/oz) from R813 791/kg (US$1 411/oz) • AISC increased by 21% to R1 180 367/kg (US$2 115/oz) from R972 261/kg (US$1 686/oz), well within guidance • AIC increased by 26% to R1 313 869/kg (US$2 354/oz) from R1 043 918/kg (US$1 810/oz). Performance by operational groupings South African underground high-grade operations Adjusted free cash flows from Mponeng and Moab Khotsong increased by 6% to R5 473 million (US$315 million) from R5 164 million (US$288 million) in H1FY25. Mponeng delivered another strong operational performance with adjusted free cash flows increasing by 30% to R4 877 million (US$281 million) from R3 761 million (US$210 million) in the comparable six months. Mponeng continues to deliver and recovered grades remained steady at 10.85g/t, well above reserve grade. This mine continues to perform exceptionally well. At Moab Khotsong, recovered grades declined by 24% as a result of planned adjustments to the mining sequence at the Great Noligwa shaft pillar, together with variability in mining mix. This was implemented to address structural seismic considerations and ensure long-term operational integrity as we continue to mine out the middle mine.

Adjusted free cash flows at Hidden Valley increased by 22% to R2 212 million (US$127 million) from R1 812 million (US$101 million) in H1FY25 while adjusted free cash flow margins remained steady at 48%. Production was however impacted by a tectonic-related mill motor failure. During the shutdown to repair the mill, necessary flotation conditioning tank repairs were also conducted. Approximately two weeks' production was lost to conduct the necessary repair work.

Integration is progressing well, guided by a dedicated Project Management Office focused on embedding Harmony’s governance framework, operating standards, and disciplined capital and risk management processes. A central priority has been welcoming and integrating the CSA workforce into the broader Harmony group, with strong emphasis on skills and leadership retention and aligning remuneration with group standards. As is throughout Harmony, safety has been our starting point. Harmony’s non‑negotiable focus on safety has already delivered meaningful improvement. The mine achieved 64 consecutive days without a lost‑time injury toward the end of the reporting period. As part of our proactive approach to safety, we undertook a planned seven‑day stoppage to upgrade a secondary egress system. Further upgrades to shaft steelwork will continue through the remainder of the financial year, and these essential safety interventions have been factored into production expectations. Safety always comes before production across all Harmony operations. Since the acquisition, CSA has produced 3 913 tonnes of high-quality copper concentrate. Production was temporarily impacted by the planned safety stoppage and by work undertaken to re-establish the correct geotechnical mining sequence at the high‑grade, high‑tonnage QTSN area, including prioritised decline development and capital ventilation projects. As part of the integration process, the mine’s cost base has already been reduced by approximately AUD26 million (R296 million; US$17 million), with further efficiencies identified by our procurement teams through strategic sourcing and tendering initiatives. Harmony is systematically addressing near‑term challenges, including ventilation constraints and underground infrastructure reliability. A dedicated project team is advancing the key capital projects that will de‑risk and de‑bottleneck the mine, ensuring a more efficient and sustainable operating platform. We anticipate the optimisation to take approximately 24 months. CSA’s underlying orebody quality remains exceptional. In line with our disciplined capital approach, development at Upper Merrin has been paused pending additional drilling to improve geological confidence. Harmony is developing an extensive integrated underground and surface drilling programme over the next 24 months. This programme, will enhance geological, geotechnical and metallurgical understanding to inform mine design, long‑term planning and potential expansion. Drilling will test the eastern margin for additional lenses across the lateral extent of the QTSN and QTSC systems – areas that remain undrilled but have already delivered significant intersections outside the current resource, highlighting strong growth potential. A deeper drilling programme, targeting extensions below the current resource, is scheduled to begin early in H1FY27. The acquisition of CSA was a deliberate long‑term strategic move to increase Harmony’s copper exposure in a Tier‑1 jurisdiction. The fundamentals of the orebody continue to validate this decision. Harmony is positioning CSA for safe, predictable production over the long term and unlocking potential regional synergies as our footprint in Australia grows. We will provide a longer-term update for the CSA copper mine with our FY26 results, including any updates to Mineral Reserves and Mineral Resources, mine plans and capital requirements. Eva Copper Project: a platform for growth Construction is underway at the Eva Copper Mine Project (Eva Copper), located in the Cloncurry shire on the traditional lands of the Kalkadoon People in North West Queensland, Australia. Since the final investment decision (FID) made by the board of directors was announced on 24 November 2025, the project scope and related site activities are progressing safely and to plan. Engineering and design, and long lead and major equipment procurement continues on schedule. Major construction contracts have been awarded, including the Engineering, Procurement and Construction contract for the process plant and non-process infrastructure awarded to Bechtel Corporation on 5 December 2025. Bechtel is expected to mobilise to site during the March quarter. Construction of the permanent accommodation village on site is progressing well and is scheduled to be completed by mid-2026. Construction of roads, bulk earthworks and civils via the alliance with Thiess Pty Ltd is on schedule. The project is on track to award a contract to an independent power provider during the March quarter for the initial start up power supply option of diesel, solar and batteries. The AUD2.3 billion (US$1.55 billion) to AUD2.6 billion (US$1.75 billion) capital estimate approved under the FID remains unchanged. The capital is spread over three years in an estimated 20/40/40 split. The capital forecast for H2 for this project is expected to be in the range of AUD235 million (US$154 million) to AUD340 million (US$222 million), subject to permitting outcomes. ›‹

MESSAGE FROM THE CHIEF EXECUTIVE OFFICER continued Harmony Gold Mining Company Limited | Interim results for the six-month period ended 31 December 2025 6 Exploration activities on the project’s mining leases continue to underline the high potential to increase mining inventory. Over 170 000 metres of drilling has been completed on the project to date, of which 21 100 metres has been completed this financial year so far. Resource and Reserve evaluation work has commenced, incorporating results from the ongoing drilling program. Sustainability is embedded in the project’s design and development. The project’s long-term social investment framework is under development in consultation with key local and regional stakeholders, including local councils, community groups and traditional owners. An application to amend the current Environmental Authority to ensure optimal operational performance against robust environmental standards is advancing through normal regulatory processes, including public consultations. We expect to be able to further update the market in the June quarter on progress. Harmony continues to collaborate with the Queensland Government on longer-term power supply options aligned with the state’s energy roadmap. Wafi-Golpu Project: a transformational asset Negotiations continue between Harmony, our joint venture partner Newmont Corporation and the Papua New Guinea Government regarding the Special Mining Lease. Harmony remains committed to permitting this Tier 1 copper-gold asset. South African surface source operations Mine Waste Solutions, Savuka Tailings, Central Plant Reclamation, Phoenix, Kalgold and rock dumps continue to generate strong adjusted free cash flows at excellent margins. Despite the industry-wide cyanide shortage which disrupted production for 12 days, adjusted free cash flows from our surface operations increased by 48% to R2 850 million (US$164 million) from R1 928 million (US$107 million) in H1FY25. Adjusted free cash flow margins increased to 42% from 34% year on year.

FY26 AISC guidance also remains unchanged at between R1 150 00/kg and R1 220 000/kg. Underground grade guidance remains unchanged at above 5.80g/t. Copper Guidance for CSA has been incorporated into the second half of the FY26 financial year. We expect production of 17 500 to 18 500 tonnes for the eight-month period ending 30 June 2026. Production at the CSA mine will be temporarily halted for approximately one month to allow for essential steel replacement on two levels of the shaft. This is a necessary intervention to ensure long‑term safety, reliability, and production stability and has been factored into the revised guidance. C1 cash costs for the remainder of this financial year are expected to be between US$2.65/lb and US$2.80/lb at a recovered grade of above 3.50%. ›‹

Harmony Gold Mining Company Limited | Interim results for the six-month period ended 31 December 2025 11 Our dividend declaration for the six months ended 31 December 2025 is as follows: Declaration of interim gross cash ordinary dividend no. 98 The Board has approved, and notice is hereby given, that an interim gross cash dividend of 530 SA cents (32.02417 US cents*) per ordinary share in respect of the six months ended 31 December 2025, has been declared payable to the registered shareholders of Harmony on Tuesday, 28 April 2026. In accordance with paragraph 7.23(a)-(k) of the JSE Listings Requirements the following additional information is disclosed: • The dividend has been declared out of income reserves; • The local Dividend Withholding Tax rate is 20%; • The gross local dividend amount is 530.00000 SA cents (32.02417 US cents*) per ordinary share for shareholders exempt from the Dividend Withholding Tax; • The net local dividend amount is 424.00000 SA cents per ordinary share for shareholders liable to pay the Dividend Withholding Tax; • Harmony currently has 636 798 966 ordinary shares in issue (which includes 11 963 973 treasury shares); and • Harmony’s income tax reference number is 9240/012/60/0. A dividend No. 98 of 530.00000 SA cents (32.02417 US cents*) per ordinary share, being the dividend for the six months ended 31 December 2025, has been declared payable on Tuesday, 28 April 2026 to those shareholders recorded in the share register of the company at the close of business on Friday, 24 April 2026. The dividend is declared in the currency of the Republic of South Africa. Any change in address or dividend instruction to apply to this dividend must be received by the company’s transfer secretaries or registrar not later than Friday, 24 April 2026. Dividends received by non-resident shareholders will be exempt from income tax in terms of section 10(1)(k)(i) of the Income Tax Act. The dividends withholding tax rate is 20%, accordingly, any dividend will be subject to dividend withholding tax levied at a rate of 20%, unless the rate is reduced in terms of any applicable agreement for the avoidance of double taxation (DTA) between South Africa and the country of residence of the shareholder. Should dividend withholding tax be withheld at a rate of 20%, the net dividend amount due to non-resident shareholders is 424.00000 SA cents per share. A reduced dividend withholding rate in terms of the applicable DTA may only be relied on if the non-resident shareholder has provided the following forms to their CSDP or broker, as the case may be in respect of uncertificated shares or the company, in respect of certificated shares: (a) a declaration that the dividend is subject to a reduced rate as a result of the application of a DTA; and (b) a written undertaking to inform the CSDP or broker, as the case may be, should the circumstances affecting the reduced rate change or the beneficial owner cease to be the beneficial owner, both in the form prescribed by the Commissioner for the South African Revenue Service. Non-resident shareholders are advised to contact their CSDP or broker, as the case may be, to arrange for the abovementioned documents to be submitted prior to the payment of the distribution if such documents have not already been submitted. In compliance with the requirements of Strate Proprietary Limited (Strate) and the JSE Listings Requirements, the salient dates for payment of the dividend are as follows: Last date to trade ordinary shares cum-dividend is Tuesday, 21 April 2026 Ordinary shares trade ex-dividend Wednesday, 22 April 2026 Record date Friday, 24 April 2026 Payment date Tuesday, 28 April 2026 No dematerialisation or rematerialisation of share certificates may occur between Wednesday, 22 April 2026 and Friday, 24 April 2026 both dates inclusive, nor may any transfers between registers take place during this period. On payment date, dividends due to holders of certificated securities on the SA share register will either be electronically transferred to such shareholders' bank accounts or, in the absence of suitable mandates, dividends will be held in escrow by Harmony until suitable mandates are received to electronically transfer dividends to such shareholders. Dividends in respect of dematerialised shareholdings will be credited to such shareholders' accounts with the relevant Central Securities Depository Participant (CSDP) or broker. The holders of American Depositary Receipts (ADRs) should confirm dividend details with the depository bank. Assuming an exchange rate of R16.55/US$1* the dividend payable on an ADR is equivalent to 32.02417 US cents for ADR holders before dividend tax.

Harmony Gold Mining Company Limited | Interim results for the six-month period ended 31 December 2025 14 The information presented in this report contains non-GAAP measures. The company presents the following non-GAAP measures: All-in sustaining cost, all-in sustaining costs per kilogram, all-in cost, cash operating costs, adjusted free cash flow. These measures should not be considered by investors in isolation or as an alternative to production costs, cost of sales, or any other measure of financial performance calculated in accordance with IFRS. Rounding differences may occur in the below reconciliations provided. The calculations of these non-GAAP measures may vary significantly among gold mining companies and, by themselves, do not necessarily provide a basis for comparison with other gold mining companies. Nevertheless, Harmony believes that these measures are useful indicators to investors and management as they provide an indication of profitability, efficiency and cash flows, the trend in costs as the mining operations mature over time on a consistent basis and an internal benchmark of performance to allow for comparison against other mines, both within the group and at other gold mining companies.

Harmony Gold Mining Company Limited | Interim results for the six-month period ended 31 December 2025 26 NOTES TO THE CONDENSED CONSOLIDATED FINANCIAL STATEMENTS FOR THE SIX MONTHS ENDED 31 DECEMBER 2025 (RAND) 1. ACCOUNTING POLICIES Basis of accounting The condensed consolidated financial statements for the interim reporting period ended 31 December 2025 have been prepared in accordance with IAS 34 Interim Financial Reporting, the JSE Limited Listings Requirements and the requirements of the Companies Act no. 71 of 2008 of South Africa. The JSE Listings Requirements require condensed financial statements to be prepared in accordance with the framework concepts and the measurement and recognition requirements of International Financial Reporting Standards (IFRS Accounting Standards) as issued by the International Accounting Standards Board (IASB), the information required by Financial Reporting Pronouncements as issued by the Financial Reporting Standards Council and SAICA Financial Reporting Guides as issued by the Accounting Practices Committee. The interim report does not include all the notes of the type normally included in an annual financial report. Accordingly, this report is to be read in conjunction with the annual financial statements for the year ended 30 June 2025. The accounting policies adopted are consistent with those of the previous financial year and corresponding interim reporting period, with the exception of the new accounting policies for copper revenue, financial assets (refer to note 2) and streaming contract liabilities (refer to note 15). There were no new standards, amendments to standards or interpretations that became effective that had a material impact on the group's results or financial position. The condensed consolidated financial statements have been prepared to the nearest million and rounding may cause differences. The condensed consolidated financial statements have been prepared on the going concern basis. Further information on liquidity and refinancing of short‑term borrowings is provided in note 18. 2. REVENUE Accounting policy – Commodities Revenue from metal sales is recognised when the group satisfies its performance obligations under its contract with the customer, by transferring such metals to the customer's control. The group sells gold, copper concentrate (including contained silver), uranium and refined silver from multiple operations with varying contract terms. Revenue is recognised at the following points of transfer of control: Gold and silver: South Africa (excluding streaming contract) Metal is delivered and certificate of sale is issued. Gold and silver: Hidden Valley Metal is collected from Hidden Valley and a confirmation of collection is sent to and accepted by the customer. Copper and silver: CSA (MAC Copper) Copper concentrate is delivered to the destination specified by the customer, which is typically the vessel on which it is shipped, the destination port or the customer’s premises and the customer has gained control. Uranium (Moab Khotsong) Confirmation of transfer is issued. The transaction price is measured based on the consideration specified in the contract with the customer and is driven by quoted market prices of the metals at the respective control transfer points. Copper and silver concentrate sales from the Cornish, Scottish and Australian (CSA) operation are provisionally priced, with the selling price subject to final adjustments based on the London Metal Exchange (LME) prices for the quotational period specified in the offtake agreement. Revenue is initially recognised when control transfers using the forward LME price to the estimated quotational period end date, net of treatment and refining charges. This forward price represents management's best estimate of the transaction price at the date control transfers. The period between initial provisional pricing and final pricing is typically between 30 and 90 days. Subsequent to initial recognition, the provisionally priced receivable is measured at fair value through profit or loss, with changes in fair value recognised as provisional pricing adjustments within revenue. Fair value is estimated by reference to forward market prices on the LME for copper and silver. Revenue arising from these price adjustments is disclosed separately from revenue from contracts with customers. For CSA copper concentrate containing both copper and silver, the transaction price is allocated to copper and silver based on their relative fair values at the date control transfers, determined by reference to forward market prices for the respective quotational periods on the LME. Both metals are provisionally priced and the receivables for both copper and silver are measured at fair value through profit or loss under IFRS 9. The group is responsible for providing certain shipping and insurance services to the customer, which is generally before the date at which the group has transferred control of the goods. These services are not distinct within the context of the contract, and they are not separately identifiable from other promises within the contract. Accordingly, shipping and insurance services are not considered separate performance obligations and are treated as costs to fulfill the promise to transfer the related products. Any customer payments of shipping and handling costs are recorded within revenue. While the group’s customer has an option to take deliveries of the goods on Cost and Freight (CFR) and Cost, Insurance and Freight (CIF) basis, the customer generally opts for Free on Board (FOB) based delivery where the group is responsible for loading the purchased goods onto the ship, and all costs associated up to that point. Accounting policy – financial assets Trade receivables resulting from the provisional copper and silver concentrate sales include actual invoiced sales of concentrate, as well as sales not yet invoiced for which deliveries have been made and the control has transferred. The copper and silver concentrate receivables are financial assets measured at fair value through profit or loss, as the solely payments of principle and interest criteria is not met. The receivable amount calculated for the concentrate delivered but not yet invoiced is recorded at the fair value of the consideration receivable at the date of delivery. At each subsequent reporting date the receivable is remeasured to reflect the fair value movements in the pricing mechanism which are recognised in revenue. Foreign exchange movements on foreign currency denominated receivables are recognised as a foreign exchange gain or loss in profit or loss subsequent to the recognition of a sale. ›‹

This was partially offset by a 11.2% decrease in gold sold from 25 167kg to 22 336kg in December 2025. (b) Copper concentrate is derived from the CSA operation in Australia acquired as part of the MAC Copper acquisition. This relates to the revenue initially recognised when control transfers using the forward LME price to the estimated quotational period end date. (c) Substantially all of the group's silver is derived from the Hidden Valley mine in Papua New Guinea. The decrease in silver revenue in December 2025 is mainly due to a 52.0% decrease in silver sold from 58 184kg to 27 947kg, as a result of a 47.6% decrease in silver produced. The decrease was offset by silver concentrate revenue of R26 million derived from the CSA operation in Australia acquired as part of the MAC Copper acquisition. This relates to the revenue initially recognised when control transfers using the forward LME price to the estimated quotational period end date. (d) Uranium is derived from the Moab Khotsong operation. The decrease is mainly due to a 43.5% decrease in uranium sold from 136 531kg to 77 111kg. (e) Relates to services rendered for the treatment of third-party gold-bearing material at the Doornkop and Moab Khotsong operations. (f) The realised effective portion of the hedge-accounted gold derivatives was impacted by the average gold market spot price of R2 122 350/kg (December 2024: R1 480 736/kg) compared to the average forward price of matured contracts of R1 389 496/kg (December 2024: R1 253 218/kg). Refer to note 9 for further information. (g) These adjustments relate to provisional pricing arrangements resulting in subsequent changes to the amount of revenue recognised. (h) A geographical analysis of revenue is provided in the segment report. ›‹

COST OF SALES Six months ended Year ended Figures in million 31 December 2025 (Reviewed) 31 December 2024 (Reviewed) 30 June 2025 (Audited) Production costs – excluding royalty (a) 21 580 20 961 41 245 Royalty expense (b) 1 439 906 1 910 Amortisation and depreciation (c) 3 241 2 428 4 842 Rehabilitation expenditure 79 47 142 Care and maintenance cost of restructured shafts 153 194 380 Employment termination and restructuring costs 105 122 200 Share-based payments 299 285 573 Reversal of impairment of assets (d) (1 074) — — Toll treatment costs 266 167 368 Other 3 1 (25) Total cost of sales 26 091 25 111 49 635 (a) The increase in production costs for the December 2025 period was due to above-inflation increases on costs such as labour and electricity. Offsetting the increase in costs partially is a R720 million inventory adjustment resulting from higher gold and copper stock on hand at period end. (b) The royalty tax increased due to a higher rate being applied as a result of higher profits, as well as the increased revenue base to which it is applied. (c) A significant portion of the increase is due to additions to property, plant and equipment following the acquisition of MAC Copper Limited (MAC Copper). Refer to notes 7 and 16 for details. (d) A reversal of previously recognised impairments in respect of property, plant and equipment of the Tshepong North CGU was recognised during the period. Refer to note 7 for details. 4. OTHER INCOME STATEMENT ITEMS Losses on derivatives The increase in derivative losses is mainly driven by the significant rise in the silver spot price during the period, which moved further above the average locked‑in floor and cap prices of the outstanding silver collar contracts. This resulted in a loss of R1.1 billion, partially offset by the realised foreign exchange derivative gain of R236 million. Finance cost R315 million of the overall increase is attributable to the bridge facility for the MAC Copper acquisition (refer to notes 13 and 16), including the amortisation of the commitment fees. Refer to note 13 for details on the facility. Also contributing to the increase for the period is the finance cost element of the streaming arrangements assumed as part of the MAC Copper acquisition, which totalled R103 million. Refer to note 15 for details. 5. TAXATION Current taxation The increased current tax expense is mainly attributable to mining taxes recognised for majority of the group's operations. The increased gold price realised resulted in a significant increase in the profitability of the group's operations for the six months ended 31 December 2025. The following legal entities contributed significantly to the current tax expense: Six months ended Year ended Figures in million 31 December 2025 (Reviewed) 31 December 2024 (Reviewed) 30 June 2025 (Audited) Harmony Gold Mining Company Limited (Harmony Company) 547 205 426 Golden Core Trade and Invest (Proprietary) Limited (Mponeng) 1 391 952 1 990 Freegold (Harmony) (Proprietary) Limited (Freegold) 575 155 365 Harmony Moab Khotsong Operations (Proprietary) Limited (Moab) 278 302 688 Randfontein Estates Limited (Randfontein) 297 118 216 ›‹

TAXATION continued Deferred taxation The movement in the net deferred tax liabilities is mainly attributable to an increase in net taxable temporary differences for majority of the group's South African mining companies as well as the deferred tax liability acquired as part of the MAC Copper acquisition (refer to note 16). The amount recognised at 31 December 2025 is as follows: At Figures in million 31 December 2025 (Reviewed) 30 June 2025 (Audited) 31 December 2024 (Reviewed) Balance at beginning of period 4 361 2 811 2 811 Expense per condensed consolidated income statement 752 2 486 492 Tax expense/(credit) directly charged to other comprehensive income (a) (543) (936) (299) Net deferred tax liability of acquired operations (b) 7 478 — — Foreign exchange translation (310) — — Balance at end of period 11 738 4 361 3 004 Deferred tax asset per condensed consolidated balance sheet (c) (153) (114) (165) Deferred tax liability per condensed consolidated balance sheet 11 891 4 475 3 169 (a) Relates to the movement in the net derivative liability position. Refer to note 9 for detail. (b) As part of the acquisition of MAC Copper, a net deferred tax liability was recognised on acquisition date. Refer to note 16 for more detail. (c) As at 31 December 2025, a deferred tax asset was recognised in Harmony Company. A deferred tax asset continues to be recognised as it is probable that sufficient future taxable profits will be available against which the remaining deductible temporary differences existing at the reporting date can be utilised. 6.

Harmony Gold Mining Company Limited | Interim results for the six-month period ended 31 December 2025 30 NOTES TO THE CONDENSED CONSOLIDATED FINANCIAL STATEMENTS continued FOR THE SIX MONTHS ENDED 31 DECEMBER 2025 (RAND) 7. PROPERTY, PLANT AND EQUIPMENT Acquisitions and business combinations One of the major contributors to the increase in property, plant and equipment is the acquisition of MAC Copper which includes the CSA Mine. Refer to note 16 for further information on the acquisition. Additions to property, plant and equipment Refer to note 17 for capital expenditure related to property, plant and equipment and additions resulting from stripping activities during the six months ended 31 December 2025. Change in estimate of environmental rehabilitation An adjustment related to the change in estimate of R336 million for the provision for environmental rehabilitation contributed to an increase in property, plant and equipment for the six months ended 31 December 2025. Refer to note 11 for further information. Foreign exchange impact The foreign exchange translation movement on property, plant and equipment from the consolidation of the group's foreign operations resulted in a decrease of R2.8 billion for the six-month period ended 31 December 2025. Depreciation of property, plant and equipment Depreciation recognised on property, plant and equipment amounted to R3.2 billion for the six-month period ended 31 December 2025. Refer to note 3 for detail. Impairment/reversal of impairment of property, plant and equipment At 31 December 2025, management performed an assessment for potential indicators of impairment of assets as well as potential indications for reversal of previously recorded impairment losses in terms of IAS 36 Impairment of Assets. Specific circumstances surrounding each of the individual cash generating units (CGUs) were considered in this assessment in order to identify significant changes in the six months since the last impairment assessment was performed. The Moab Khotsong, Tshepong North, Tshepong South, Joel, Target 1 and Masimong CGUs experienced operational issues during the six months ended 31 December 2025. These operational issues were considered to be indications of potential impairment and therefore an impairment assessment was performed for these CGUs. Additionally, on 24 November 2025 the final investment decision for Eva Copper was approved, thereby resulting in its technical and commercial viability being demonstrable. On this date, Eva Copper was reclassified from undeveloped properties to mining assets under construction. In accordance with IFRS 6 Exploration for and Evaluation of Mineral Resources, an impairment assessment was performed for Eva Copper prior to its reclassification to mining assets under construction. For CGUs that had previously been impaired, management first determined the carrying amounts that would have existed (net of depreciation) had no impairment losses been recognised in prior periods. Where this depreciation had not eliminated the depreciable amount available for reversal, management then assessed whether the impairment loss may no longer exist or may have decreased, including whether the estimated service potential of each CGU had increased in a sustained manner since the impairment was recognised. Indicators that a previously recognised impairment loss may no longer exist or may have decreased were identified for the Tshepong North operation. Management also performed assessments for the Tshepong South and Target 1 operations and concluded that no reversal of previously recognised impairments of these CGUs was required as at 31 December 2025. Critical estimates and judgements The recoverable amount of mining assets is determined utilising real discounted future cash flows. The real post-tax discount rate used for CGUs tested for impairment and reversal of impairments ranged between 8.1% and 13.5% as at 31 December 2025 (December 2024: 10.6% and 11.9%). No material difference in recoverable amounts is expected should future cash flows be discounted on a pre-tax basis. ›‹

PROPERTY, PLANT AND EQUIPMENT continued Impairment of property, plant and equipment continued Critical estimates and judgements continued The commodity price and exchange rate assumptions applied in the impairment assessments are as follows: Six months ended Year ended 31 December 2025 (Reviewed) 31 December 2024 (Reviewed) 30 June 2025 (Audited) US$ gold price per ounce – Year 1 4 109 2 661 3 105 – Year 2 3 905 2 549 2 892 – Year 3 3 508 2 382 2 604 – Long term (Year 4 onwards) 2 915 1 941 2 237 Exchange rate (R/US$) – Year 1 17.20 17.76 17.95 – Year 2 17.11 17.32 17.63 – Year 3 17.56 17.00 18.01 – Long term (Year 4 onwards) 17.60 18.54 18.54 Rand gold price (R/kg) – Year 1 2 272 000 1 520 000 1 792 000 – Year 2 2 149 000 1 420 000 1 639 000 – Year 3 1 981 000 1 302 000 1 508 000 – Long term (Year 4 onwards) 1 649 000 1 157 000 1 334 000 Copper price (US$/lb) – Year 1 4.94 n/a n/a – Year 2 4.81 n/a n/a – Year 3 4.72 n/a n/a – Long term (Year 4 onwards) 4.75 n/a n/a The recoverable amounts of the CGUs were determined on a fair value less cost to sell basis. This is a fair value measurement classified as level 3 within the fair value hierarchy. All key assumptions disclosed remained the same as at 30 June 2025 with the exception of the commodity prices, exchange rates and discount rates as disclosed above. Results of impairment and reversal assessment Based on the impairment tests performed, no impairments were recorded for the six-month period ended 31 December 2025. During the year ended 30 June 2022, an impairment of R2.3 billion was recognised in respect of property, plant and equipment relating to the Tshepong North CGU. At 31 December 2025, a reversal of impairment of R1.1 billion in respect of property, plant and equipment relating to the Tshepong North CGU was recognised. This reversal reflects an increase in the recoverable amount of the CGU (fair value less costs of disposal, Level 3 in the fair value hierarchy), as a result of significantly higher gold price assumptions applied in the valuation at 31 December 2025. The recoverable amount of the Tshepong North CGU at 31 December 2025 was determined as R3.6 billion. A reasonable possible change in assumptions would not change the conclusion to reverse the impairment or the quantum of the reversal. The reversal of impairment is presented as part of cost of sales on the condensed consolidated income statement. 8. RESTRICTED CASH AND INVESTMENTS The balance at 31 December 2025 increased by R481 million as a result of interest received as well as the mark-to-market valuation of these funds. ›‹

INVENTORIES Inventories increased by R1.0 billion during the period. The increase was due to a R273 million increase in commodity inventories at Hidden Valley, which was driven primarily by a delayed December shipment. In addition, there was a R198 million increase in the South African operations' commodity inventories as a result of higher average valuation rates. Copper inventories of R306 million were included as a result of the MAC Copper acquisition. Furthermore, consumables increased by R231 million in anticipation of supplier closures during December. 11. PROVISION FOR ENVIRONMENTAL REHABILITATION The increase in the provision of R677 million is mainly due to the change in estimate of R425 million as a result of a decrease in discount rates. In addition to this change, an additional R222 million was assumed as part of the acquisition of MAC Copper. ›‹

(a) The decrease is mainly due to the settlement of the additional mineral resources declaration of R256 million. (b) The increase in the contingent consideration liability is mainly as a result of the MAC acquisition. The contingent consideration arrangements existed prior to Harmony's acquisition of MAC Copper and originated with MAC Copper's acquisition of CSA from Glencore on 15 June 2023. These obligations include: • copper price‑linked contingent consideration; and • a net smelter return (NSR) royalty contingent consideration. Copper price-linked contingent consideration The copper contingent consideration totals US$150 million, structured as two unsecured and fully subordinated contingent payments of US$75 million each (the first contingent copper payment and the second contingent copper payment). These amounts become payable only if the following price‑based conditions are met over the life of the mine: • First contingent copper payment: The average daily LME closing copper price exceeds US$4.25/lb (US$9 370/mt) for any rolling 18‑month period from 15 June 2023 and • Second contingent copper payment: The average daily LME closing copper price exceeds US$4.50/lb (US$9 920/mt) for any rolling 24‑month period from 15 June 2023. The copper contingent consideration is measured at fair value through profit or loss. Refer to note 18 for the details of the valuation. NSR royalty contingent consideration Under the NSR agreement, Cobar Management Proprietary Limited (CMPL) is required to pay Glencore a 1.5% NSR royalty on all marketable, metal‑bearing copper material produced from the mining tenure held by CMPL at 15 June 2023. The NSR royalty contingent consideration is measured at fair value through profit or loss. Refer to note 18 for the details of the valuation. ›‹

The purpose of the agreement is to secure funding to finance the acquisition of MAC Copper and related costs (refer to note 16 for further information). Under the agreement, a US$250 million facility (Facility A) and a US$1 billion facility (Facility B) were made available to Harmony Australia and Harmony, respectively. The tenure of the loan is 364 days with a six-month extension option. The period of the draw down has lapsed therefore, the balance of the facility is no longer available. Origination fees of R253 million were incurred for the facility. These fees are regarded as an integral part of the effective interest rate of the facility and are treated as transaction costs. The interest rate terms vary as follows: • SOFR + 2% for the first six months starting 26 May 2025 • SOFR + 2.80% for the next six months • SOFR + 4% for the last six months. (b) This facility can only be drawn for qualifying projects. (c) On 24 October 2025, Harmony took over the senior syndicated facility from MAC Copper. On 28 October 2025 the outstanding balance was fully repaid and the facility was extinguished. (d) On 3 December 2025, the South African Reserve Bank (SARB) announced the cessation of the JIBAR as of 31 December 2026. South Africa's financial market is moving away from the JIBAR benchmark to the South African Rand Overnight Index Average (ZARONIA). As these facilities’ agreements makes provision for the use of replacement benchmarks for determining interest rates, the impact of the South African IBOR reform is expected to be immaterial. ›‹

Subsequently a US$200 million (R3.3 billion) repayment was made on facility B. • Senior syndicated facility – On 24 October 2025, Harmony took over the senior syndicated facility from MAC Copper amounting to US$223 million (R3.9 billion), which included both principal and accrued interest. On 28 October 2025, a payment of US$223 million (R3.8 billion) was made to Citicorp International Limited in full as final settlement of the MAC Copper senior debt. The debt covenant tests for both the Rand and the US$ facilities are as follows: • The group's interest cover ratio shall be more than five times (EBITDA1/Total Interest paid) • Leverage2 shall not be more than 2.5 times. 1 Earnings before interest, taxes, depreciation and amortisation (EBITDA) as defined in the agreement also excludes unusual items such as impairment and restructuring cost. 2 Leverage is defined as total net debt to EBITDA. Loan covenants tests were performed for the loans for the period ended 31 December 2025 and no breaches were noted. For the December 2025 period, the group's interest cover ratio was 57.4 times (December 2024: 64.8 times) (June 2025: 97.3 times), while the group's leverage was 0.2 (December 2024: negative 0.3) (June 2025: negative 0.4). Management believes that it is very likely that the covenant requirements will be met in the foreseeable future given the current earnings and interest levels. 14. TRADE AND OTHER PAYABLES The balance at 31 December 2025 increased by R1.8 billion.

(OR Royalties), which have been accounted for as financial liabilities containing embedded derivatives in accordance with IFRS 9, Financial Instruments. The embedded derivatives relate to the applicable commodity price exposure within the contractual delivery obligations. The copper streaming arrangement also includes an embedded derivative relating to a buy-down option. The embedded derivatives have been separated from the host contracts and are measured at fair value through profit or loss. On initial recognition in accordance with IFRS 3, Business Combinations, the copper and silver host contract financial liabilities were recognised at fair values of R2.3 billion and R2.6 billion, respectively, while the embedded derivatives were recognised at fair values of R199 million asset (copper compound derivative) and Rnil (silver derivative). Subsequent to initial recognition (i) Host contracts (financial liabilities) The host contracts are measured at amortised cost using the effective interest method. Interest expense is calculated by applying the effective interest rates of 13.22% (copper) and 13.53% (silver) to the respective amortised cost carrying amounts and is recognised in finance costs. When expected future physical deliveries of the applicable commodity are revised due to changes in mine production or reserve estimates, the carrying amount of the financial liability is recalculated as the present value of revised estimated future cash flows discounted at the original effective interest rate (in accordance with IFRS 9 paragraph B5.4.6). The resulting catch-up adjustment is recognised immediately in finance costs. (ii) Embedded derivatives The embedded derivatives measured at fair value through profit or loss at each reporting period, with changes in fair value recognised in fair value movements on streaming arrangements. Fair value is determined using Level 3 inputs within the fair value hierarchy (see note 18 for details on the fair value measurement). The streaming arrangement liabilities are presented separately on the condensed consolidated balance sheet as streaming contract liabilities, split between current and non-current portions based on expected delivery schedules.

MAC Copper has a 100% interest in the CSA copper mine, its sole asset, which is located in the Cobar Region of New South Wales, Australia. The acquisition supports Harmony’s strategic objective of transitioning into a low-cost, global gold and copper mining company. Based on management's assessment the transaction meets the definition of a business combination as defined by IFRS 3 Business Combinations. Upon completion of the transaction, the following obligations of MAC Copper have been assumed by Harmony: • The silver purchase agreement (silver stream) with OR Royalties pursuant to which OR Royalties receives refined silver equal to 100% of the payable silver production from CSA and makes ongoing payments equal to 4% of the spot silver price per ounce at the time of delivery (refer to note 15) • The copper purchase agreement (copper stream) with OR Royalties pursuant to which OR Royalties receives refined copper equal to 2.25% to 4.875% of the payable copper production from CSA, which amounts may be reduced through the exercise of a buy-down option, with OR Royalties making ongoing payments equal to 4% of the spot copper price per tonne at the time of delivery (refer to note 15) • The royalty deed with Glencore Operations Australia (Pty) Limited (Glencore) pursuant to which Glencore is entitled to a 1.5% net smelter return royalty over the life of the CSA mine (refer to note 12) and • The sale and purchase agreement between MAC and Glencore relating to US$150 million of contingent payments, where a once-off payment of US$75 million is due in the event that the copper price averages more than US$4.25/lb for 18 continuous months at any stage during the life of the CSA mine and a further once-off payment of US$75 million in the event that the copper price averages more than US$4.50/lb for 24 continuous months during the life of the CSA mine (refer to note 12). ›‹

Cash generating units identified CSA, with its associated assets and liabilities, was identified as the only CGU. Consideration transferred The consideration for the transaction is a cash payment of US$12.25 per MAC Copper share, amounting to US$1.0 billion (R17.5 billion) paid on 23 October 2025. The amount disclosed in the condensed consolidated cash flow statement for cash paid for the acquisition of MAC Copper is determined as follows: At Figures in million 24 October 2025 (Reviewed) Cash consideration paid 17 480 Cash acquired (420) Net cash paid on 24 October 2025 17 060 Acquisition-related costs The total of R1.4 billion for acquisition costs for the six months ended 31 December 2025 relates to various costs directly attributable to the acquisition process. These costs include stamp duty, attorney and advisory fees. There have also been costs incurred for the integration of the acquired assets into Harmony's existing structures and systems. These costs include project management and consultancy fees. These costs amounted to R16 million for the period ended 31 December 2025 and have been included in Corporate, administration and other expenditure. Identifiable assets acquired and liabilities assumed The fair value exercise was prepared on a provisional basis in accordance with IFRS 3. The values measured on a provisional basis included, inter alia, property, plant and equipment, streaming contract liabilities, contingent consideration liabilities, provision for environmental rehabilitation and the resultant deferred tax associated with these balances. Management is still in the process of gathering and assessing certain information on key estimations and the impact thereof on the provisional fair values. No measurement period adjustments have been recognised for the six-month period ended 31 December 2025. The measurement period ends on 23 October 2026. Any information that materially impacts on amounts previously recorded will be considered when finalising the fair value exercise. Critical estimates and assumptions of business valuations performed The provisional fair value of the identifiable net assets acquired was determined based on the fair value of the consideration transferred for the transaction. This was further supported by the expected discounted cash flows based on the life of mine plan of CSA. Key assumptions for the level 3 fair value measurement of CSA includes real copper prices ranging from US$4.75/lb to US$5.35/lb, real silver prices ranging from US$32.31/oz to US$51.02/oz, real zinc prices ranging from US$1.27/lb to US$1.33/lb, a marketable post-tax real discount rate of 7.75%, US$/A$ exchange rates ranging from US$0.66/A$1 to US$0.69/A$1 and the CSA life-of-mine plan. Mineral resources acquired which were not included in the discounted cash flows were valued using a zinc resource multiple price of US$0.04/lb. The valuation was performed as at 24 October 2025. The tax rates used to calculate deferred tax is based on Australian tax rates and tax laws that have been enacted at acquisition date. The deferred tax rate used as at 24 October 2025 was 30%. ›‹

Performance of acquired operations For the six months ended 31 December 2025, the acquired operation contributed revenue of R480 million and a net loss of R1.2 billion since acquisition date. Should the acquisition have occurred on 1 July 2025, the group’s pro forma consolidated revenue would have been R47.1 billion and pro forma consolidated profit would have been R11.2 billion. The following information was used to determine the revenue and net loss for the acquired operation for the period 1 July 2025 to 31 December 2025: • 1 July 2025 to 24 October 2025: The revenue and net profit per the CSA trial balance for the period 1 July 2025 to 24 October 2025. • 25 October 2025 to 31 December 2025: The revenue and net loss for MAC Copper as included as part of the condensed consolidated income statement for the six months ended 31 December 2025. • The revenue and net loss in A$ terms for the periods 1 July 2025 to 24 October 2025 and 25 October 2025 to 31 December 2025 as determined above, were translated using the average Rand/A$ exchange rate of R11.49/A$1 and R11.21/A$1, respectively. ›‹

Harmony Gold Mining Company Limited | Interim results for the six-month period ended 31 December 2025 46 NOTES TO THE CONDENSED CONSOLIDATED FINANCIAL STATEMENTS continued FOR THE SIX MONTHS ENDED 31 DECEMBER 2025 (RAND) 18. FINANCIAL RISK MANAGEMENT ACTIVITIES Foreign exchange risk Harmony's revenues are sensitive to the R/US$ exchange rate as majority of revenues are denominated in US$. A weakening of the Rand will increase the reported revenue total; conversely a strengthening will decrease it. Harmony maintains a foreign currency derivative programme to manage foreign exchange risk. The limit currently set by the Board is 25% of the group's foreign exchange risk exposure for a period of 24 months. The audit and risk committee reviews the details of the programme quarterly. Refer to note 9 and the fair value determination section below for further detail on these contracts. The Rand strengthened during the six months ended 31 December 2025 from a closing rate of R17.75/US$1 on 30 June 2025 to R16.56/US$1 on 31 December 2025 (31 December 2024: R18.85/US$1). The strengthening of the Rand resulted in the average locked-in rates being higher than the spot exchange rate at 31 December 2025, which had a positive impact on the contracts that matured during the period as well as those that were outstanding as at 31 December 2025. The appreciation of the Rand and Australian dollar also had a positive impact on the translation of the US$ debt facilities at 31 December 2025. Translation of the international net assets was impacted by the acquisition of MAC Copper and the strengthening of the Rand against the Australian dollar from R11.68/A$1 at 30 June 2025 to R11.06/A$1 on 31 December 2025 (31 December 2024: R11.70/A$1). This impact was partially offset by the Kina weakening against the Australian dollar from a closing rate of PGK2.72/A$1 on 30 June 2025 to PGK2.84/A$1 on 31 December 2025 (31 December 2024: PGK2.51/A$1). The translation from Kina to Australian dollar and Australian dollar to Rand combined with the average rate at which income statement items were translated at, resulted in a foreign exchange translation loss of R2.3 billion for the period ended 31 December 2025. The relevant exchange rates traded in the following ranges: Six months ended 31 December 2025 (Reviewed) 31 December 2024 (Reviewed) R/US$ foreign exchange rate range for the period 16.56 – 18.20 17.10 – 18.85 R/A$ foreign exchange rate range for the period 11.06 – 11.81 11.29 – 12.41 A$/PGK foreign exchange rate range for the period 2.67 – 2.90 2.49 – 2.75 Commodity price sensitivity The profitability of the group’s operations, and the cash flows generated by those operations, are mainly affected by changes in the market price of gold, silver (in the case of Hidden Valley), uranium (in the case of Moab Khotsong) and copper following the acquisition of MAC Copper. Harmony enters into derivative contracts to manage the variability in cash flows from the group’s production, in order to create cash certainty and protect the group against lower commodity prices. During the period under review, the group's cash inflows from uranium were managed by way of a forward contract entered into, whereby uranium prices are predetermined for a limited amount of uranium production. The limit for gold hedging as set by the Board is 30%, 20% and 10% of production in a 12-, 24- and 36-month period, respectively, for contracts going forward. The limit set by the Board is 50% of silver exposure over a 24-month period and 50% for uranium exposure over a 60-month period. As part of the MAC Copper acquisition, Harmony took over the copper derivative contracts related to production at the CSA copper mine. Refer to note 16. The audit and risk committee reviews the details of the programme quarterly. Refer to note 9 and the fair value determination section below for further detail on these contracts. An increase in the price of gold in US$ terms resulted in the average locked-in gold forward prices being lower than the gold spot price which had a negative impact on the gold forward hedging contracts that matured during the period as well as those that were outstanding as at 31 December 2025. The average cap prices were also lower than the gold spot price of the remaining gold zero cost collar contracts, resulting in a negative valuation as at 31 December 2025. The average cap prices of the remaining silver zero cost collar contracts were lower than the silver spot price resulting in a negative valuation at 31 December 2025 and moving the asset position at 31 December 2024 to a liability position. Gold, copper and silver traded in the following ranges: Six months ended 31 December 2025 (Reviewed) 31 December 2024 (Reviewed) Gold price range in US$/oz for the period 3 275 – 4 532 2 329 – 2 786 Copper price range in US$/tonne for the period 9 607 – 12 674 n/a Silver price range in US$/oz for the period 36.06 – 79.15 26.60 – 34.83 Interest rate risk With inflation rates easing and economies recovering, central banks continued to reduce interest rates during the six months ended 31 December 2025. The group has therefore not entered into interest rate swap agreements as the interest rate risk continues to be assessed as low. Further to this, the decreased interest rates have lowered bond yields and this has resulted in a decrease in discount rates. This impact can be seen in the change in the environmental rehabilitation provision. Refer to note 11 for further information. The audit and risk committee reviews the group's risk exposure quarterly. ›‹

FINANCIAL RISK MANAGEMENT ACTIVITIES CONTINUED Credit risk Credit risk is the risk that a counterparty may default or not meet its obligations in a timely manner. Financial instruments which are subject to credit risk are restricted cash and investments, derivative financial instruments and cash and cash equivalents, all of which are invested with financial institutions that meet the group's policy requirements for credit quality, as well as trade and other receivables (excluding non-financial instruments). In assessing the creditworthiness of local institutions, management uses the national scale long-term ratings. At 31 December 2025, the national scale investment grade rating of the major South African banks remained unchanged at AA+, which is in line with the group's credit risk policy. An assessment of the expected credit losses (ECLs) for the financial assets measured at amortised cost at 31 December 2025 resulted in an immaterial amount for each instrument. The credit rating of the group's Australian counterparts remained at AA- at 31 December 2025. The assessed ECL remained immaterial. Management will continue to review the underlying strength of the economies we operate in as well as the creditworthiness of the financial institutions and make any changes deemed necessary to safeguard the assets and reduce the credit risk. Liquidity risk At 31 December 2025, current liabilities exceeded current assets, primarily due to short‑term interest‑bearing borrowings and derivative financial liabilities. These borrowings are expected to be refinanced in the ordinary course of business and the group has access to sufficient committed facilities to meet its obligations as they fall due. The group remains in compliance with all financing covenants, and the directors are satisfied that the group has adequate resources to continue in operational existence for the foreseeable future. Undrawn committed facilities at 31 December 2025 amounted to R7.5 billion (refer to note 13), providing additional headroom for the group’s funding requirements. Capital risk management The acquisition of MAC Copper was funded through cash reserves and a bridge loan of US$1.25 billion. The company drew down US$875 million (R15.2 billion) for the acquisition and related costs resulting in an increase in borrowings at 31 December 2025. The group made repayments of R7.2 billion during the six months ended 31 December 2025 (31 December 2024: nil) (30 June 2025: R50 million), decreasing the cash and cash equivalents at 31 December 2025. Refer to note 13 for further details.

FINANCIAL RISK MANAGEMENT ACTIVITIES continued Fair value determination The fair value levels of hierarchy are as follows: Level 1: Quoted prices (unadjusted) in active markets Level 2: Inputs other than quoted prices included within level 1 that are observable for the asset, either directly (that is, as prices) or indirectly (that is, derived from other prices) Level 3: Inputs for the asset that are not based on observable market data (that is, unobservable inputs). The following table sets out the group's assets and liabilities measured at fair value by level within the fair value hierarchy: At Figures in million Fair value hierarchy level 31 December 2025 (Reviewed) 30 June 2025 (Audited) 31 December 2024 (Reviewed) Fair value through other comprehensive income Other non-current assets (a) Level 1 76 — — Other non-current assets (a) Level 3 105 107 89 Restricted cash and investments (b) Level 1 447 384 355 Fair value through profit or loss Restricted cash and investments (b) Level 2 2 022 1 828 1 652 Derivative financial assets (c) Level 2 486 568 414 Derivative financial liabilities (c) Level 2 (12 726) (7 747) (4 404) Trade and other receivables (d) Level 2 358 86 — Loan to ARM BBEE Trust (e) Level 3 36 45 53 Contingent consideration liabilities (f) Level 3 (3 495) (1 457) (1 267) Streaming contract liabilities (g) Level 3 646 — — (a) The level 1 valued assets comprise of listed equity securities held by MAC Copper and are designated at fair value through other comprehensive income. The level 3 valued instruments comprise mainly of the equity investment in Rand Mutual. The fair value of the investment in Rand Mutual was estimated with reference to an independent valuation. A combination of the "Embedded Valuation" and "Net Asset Value" techniques were applied to revalue the investment at 30 June 2025. In evaluating the group's share of the business, common practice marketability and minority discounts as well as additional specific risk discounts were applied. There are no inputs to the valuation that a reasonably possible change would result in a material change in the fair value of the investment. At 31 December 2025 an updated valuation was not performed as no material changes had occurred. (b) The level 1 valued assets comprise of listed equity securities designated as fair value through other comprehensive income instruments. The majority of the level 2 valued assets are directly derived from the Top 40 index on the JSE and are discounted at market interest rates. This relates to equity-linked deposits in the group's environmental rehabilitation trust funds. The remaining balance of the environmental trust funds is carried at amortised cost and therefore not disclosed here. (c) The mark-to-market remeasurement of the derivative contracts (refer to note 9 for further details) was determined as follows: • Foreign exchange contracts comprise of zero cost collars and forward exchange contracts (FECs): The zero cost collars were valued using a Black-Scholes valuation technique derived from spot Rand/US$ exchange rate inputs, implied volatilities on the Rand/US$ exchange rate, Rand/US$ inter-bank interest rates and discounted at a market interest rate (zero-coupon interest rate curve). The value of the FECs is derived from the forward Rand/US$ exchange rate and discounted at a market interest rate (zero-coupon interest rate curve) • Rand gold forward sale contracts: spot Rand/US$ exchange rate, Rand and dollar interest rates (forward points), spot US$ gold price, differential between the US interest rate and gold lease interest rate which is discounted at a market interest rate • US$ gold forward sale contracts: spot US$ gold price, differential between the US interest rate and gold lease interest rate and discounted at a market interest rate • US$ copper swap contracts: spot US$ copper price, differential between the US interest rate and copper lease interest rate and discounted at a market interest rate • Silver contracts (zero cost collars): a Black-Scholes valuation technique, derived from spot US$ silver price, strike price, implied volatilities, time to maturity and interest rates and discounted at a market interest rate • Rand gold zero cost collar contracts: a Black-Scholes valuation technique, derived from spot Rand/US$ exchange rate, spot US$ gold price, Rand and dollar interest rates (forward points) with discounting at the market interest rate (zero-coupon interest rate curve), US$ gold forward rates, time to maturity and implied volatilities • US$ gold zero cost collar contracts: a Black-Scholes valuation technique, derived from spot US$ gold price, US$ gold forward rates, US$ interest rates with discounting at the market interest rate (zero-coupon interest rate curve), time to maturity and implied volatilities. (d) The fair value of receivables arising from copper and silver concentrate sales contracts at 31 December 2025 which contain provisional pricing mechanisms are determined using the appropriate quoted forward price from the exchange that is the principal active market for the particular metal. As such, these receivables, which have the characteristics of a commodity derivative, are classified within Level 2 of the fair value hierarchy. ›‹

Harmony Gold Mining Company Limited | Interim results for the six-month period ended 31 December 2025 49 NOTES TO THE CONDENSED CONSOLIDATED FINANCIAL STATEMENTS continued FOR THE SIX MONTHS ENDED 31 DECEMBER 2025 (RAND) 18. FINANCIAL RISK MANAGEMENT ACTIVITIES continued Fair value determination continued (e) At 31 December 2025, the fair value movement was calculated using a discounted cash flow model, taking into account forecast dividend payments over the estimated repayment period of the loan at a rate of 11.0% (31 December 2024: 12.0%) (30 June 2025: 11.5%). A 55 basis points (31 December 2024: 60 basis points) (30 June 2025: 28 basis points) change in the discount rate, which would represent a reasonably possible change based on expected movements in lending rates, would not cause a material change in the fair value of the loan. The loan balance forms part of other non-current assets in the condensed consolidated balance sheet. During the six-month period ended 31 December 2025, repayments to the value of R12 million (31 December 2024: R18 million) (30 June 2025: R28 million) were received. (f) Contingent consideration liabilities consist of the following: • Mponeng operation The contingent consideration liability related to the Mponeng operation was determined using the expected gold production profile for Mponeng. At 31 December 2025, the liability was valued at R711 million (31 December 2024: R843 million) (30 June 2025: R676 million), using a discounted cash flow valuation method at a post-tax real rate of 11.8% (31 December 2024: 10.2%) (30 June 2025: 10.8%). Should the expected gold production profile increase by 11.9% or decrease by 11.9%, the contingent consideration liability would increase by R341 million (31 December 2024: R631 million at 15.7%) (30 June 2025: R319 million at 11.5%) or decrease by R341 million (31 December 2024: R500 million at 15.7%) (30 June 2025: R319 million at 11.5%) respectively. This represents reasonably expected changes which were determined based on the average variance between the planned production and the actual production achieved over a number of years. No other reasonably expected changes in key unobservable inputs would have caused a material change in the fair value of the liability. • Eva Copper The consideration for Eva Copper includes contingent consideration valued at R511 million (31 December 2024: R424 million) (30 June 2025: R781 million), using a probability weighted method for the new resource payment and a discounted cash flow valuation for the excess payment, both discounted at a post-tax nominal rate of 11.2% (31 December 2024: 10.8%) (30 June 2025: 11.4%). A long-term copper price of US$4.75/lbs (31 December 2024: US$4.25/lbs) (30 June 2025: US$4.25/lbs) was applied in the valuation. A 10.8% change in the long-term copper price, which would represent a reasonably possible change based on the standard deviation of market analysts long-term forecasts of the copper price, would not cause a material change in the fair value of the contingent consideration. • Copper price‑linked contingent consideration The second contingent copper payment of the copper price‑linked contingent consideration was valued at R1.2 billion, using a probability weighted method. Owing to the elevated copper price environment currently experienced, it is estimated that the second contingent copper payment of US$75 million is highly likely to be triggered within the next 12 months, therefore the contingent consideration has been valued at 31 December 2025 at its expected settlement amount. A 5% change in the short-term copper price, which would represent a reasonably possible change based on the standard deviation of market analysts short-term forecasts of the copper price, would not cause a material change in the fair value of this contingent consideration. The remeasurement of the liability is presented as a separate line item in the condensed consolidated income statement. • NSR royalty The NSR royalty was valued at R1.0 billion, using a discounted cash flow valuation, discounted at a post-tax real discount rate of 7%. The valuation is determined using the present value of the expected discounted cash flows over the expected life-of-mine of CSA. Expected cash flows are determined by making use of market analyst forecasts of the copper price and after deducting for the estimated treatment and refining charges in terms of the existing offtake agreement with Glencore. A 10.8% change in the long-term copper price, which would represent a reasonably possible change based on the standard deviation of market analysts long-term forecasts of the copper price, would not cause a material change in the fair value of the NSR royalty. The remeasurement of the liability is presented as a separate line item in the condensed consolidated income statement. (g) The streaming contract liabilities balance includes a copper compound and silver embedded derivative valued at R26 million and R620 million, respectively. These liabilities were assumed by the group on acquisition of MAC Copper and are measured at fair value through profit or loss. Refer to note 15. • The copper compound derivative relates to the embedded copper price within the copper stream and the buy-down option. The copper compound derivative is valued using a copper future curve simulation valuation model and a Monte-Carlo valuation for the buy-down option at each reporting date. The following key assumptions were used in the valuation of the copper compound derivative: Copper spot price (per tonne) of US$12 504 per tonne, LME Copper implied volatility of 23.0% and own credit spread 8.2%. In isolation, at 31 December 2025, a 5% increase/decrease in copper spot price, which would represent a reasonably possible change based on the standard deviation of market analysts' short-term forecasts of the copper price, would not cause a material change in the fair value of the copper stream embedded derivative liability. • The silver derivative relates to the embedded silver price within the silver stream. The silver derivative is valued using a silver future curve simulation valuation model at each reporting date. The following key assumptions were used in the valuation of the silver derivative: Silver spot price of US$70.13/oz and own credit spread of 7.5%. In isolation, at 31 December 2025, a 10% increase/decrease in silver spot price, which would represent a reasonably possible change based on the standard deviation of market analysts' short-term forecasts of the silver price, would not cause a material change in the fair value of the silver derivative liability. The carrying values (less any impairment allowance) of short-term financial instruments are assumed to approximate their fair values. This includes restricted cash and investments carried at amortised cost. The carrying values of borrowings fairly approximates their fair values, as these values do not differ materially due to the interest payable on the borrowings being set at market-related floating interest rates. ›‹
