3 Harmony Gold Mining Company Limited | FY23 Results for the year ended 30 June 2023 OVERVIEW The past financial year was filled with many highlights as Harmony delivered on its strategic objectives of producing safe, profitable ounces through operational excellence and value-accretive acquisitions. We saw an improved safety performance while meeting our production, cost and grade guidance as we continue navigating a challenging operating landscape. It is worth noting that our costs have remained under control despite the current high inflationary environment. Embedded sustainability practices, improved asset quality and operational consistency resulted in a strong and sustainable group performance with solid operational free cash flows. Harmony is South Africa's largest gold mining company by volume. Globally, we are the largest producer of gold from the retreatment of old tailings dams, making us a major player in the circular economy. We are investing in copper as we understand the critical role that this future- facing metal has in transitioning towards a low-carbon economy. We are therefore, allocating growth capital towards high-margin, long-life operating assets while progressing our two key international projects, namely Eva Copper in Queensland, Australia and the Tier 1 Wafi-Golpu copper-gold project in Papua New Guinea. As we expand internationally, we will continue to build trust by partnering with our stakeholders to ensure long-term, shared value-creation, as we have done for over 73 years. Health and safety is our number one priority. We remain focused on achieving zero harm through an integrated risk-based approach and a proactive safety culture. For the second consecutive year, the group lost time injury frequency rate (LTIFR) was below 6 per million hours worked. Our goal remains to ensure all our people return home safely every single day. In our quest to achieve carbon net zero by 2045, we are investing in renewable energy and reducing consumption through various energy efficiency programmes. We are also closely managing the impact of energy shortages affecting South Africa and we have a clear strategy in place to mitigate potential risks. Phase 1 of our renewable energy programme has been commissioned, delivering 30MW of generation capacity to our Free State operations. This will reduce our peak Free State operations' daytime demand by approximately 20%, or 6% of our South African operations' total demand. These initiatives will alleviate pressure on the national grid whilst furthering our decarbonisation strategy. Gold revenue for the group increased by 14% to R47 519 million (US$2 675 million) in FY23 compared to R41 742 million (US$2 744 million) in FY22. This increase was due to higher underground recovered grades which increased by 8% to 5.78g/t in FY23 from 5.37g/t in FY22. This was further supported by the higher average gold price received which increased by 15% to R1 032 646/kg (US$1 808/oz) in FY23 from R894 218/kg (US$1 829/oz) in the previous reporting period. Group production in FY23 was steady, decreasing by 1% to 45 651kg (1 467 715oz) from 46 236kg (1 486 517oz) in FY22. However, adjusting for the closure of Bambanani at the end of FY22, group production increased by 2% or 848kg (27 270oz) year-on-year. Production was mainly driven by an excellent operating performance from our South African underground operations and an 18% or 663kg (21 316 oz) increase in Hidden Valley production. Group AISC increased by 6% to R889 766/kg (US$1 558/oz) in FY23 from R835 891/kg (US$1 709/oz) in FY22. Higher underground recovered grades and a stable cost base ensured AISC came in below the guided R900 000/kg for this financial year. We are pleased with this increase given the high-inflationary environment currently being experienced globally. Group all-in costs (AIC) increased by 9% to R938 997/kg (US$1 644/oz) from R865 237/kg (US$1 769/oz) as a result of our major projects. These projects include the Kareerand tailings storage facility (TSF) expansion at Mine Waste Solutions, and Zaaiplaats which is the Moab Khotsong life of mine extension project. Total capital spent in FY23 was R7 598 million (US$428 million). This was R402 million (US$22 million) lower than the guided R8 billion (US$450 million) due to permitting delays at Kareerand TSF extension. Group operating free cash flows increased by 108% to R6 031 million (US$339 million) in FY23 from R2 905 million (US$191 million) in FY22 due to the higher underground recovered grades and the higher average gold price received. Our underground high-grade operations, Moab Khotsong and Mponeng, contributed 57% towards group operating free cash flows. Maintaining a robust and flexible balance sheet with strong liquidity is prudent as we expand internationally. With the acquisition of Eva Copper on 16 December 2022, net debt/EBITDA increased from 0.1 to 0.6 times. Due to the strong cash flows generated throughout the financial year, we have repaid debt of R2 045 million (US$115 million) since December 2022, resulting in net debt/EBITDA of 0.2 times at the end of the financial year. Headroom of R7 250 million (US$385 million) is available through cash and undrawn facilities and will be used to achieve our strategic objectives. Basic earnings per share increased by 553% to 780 SA cents (44 US cents) compared to a loss of 172 SA cents (8 US cents) per share in the previous reporting period. Headline earnings per share increased by 60% to 800 SA cents (45 US cents) per share compared to 499 SA cents (33 US cents) per share in FY22. Harmony’s dividend policy is to return 20% of net free cash generated (net free cash is defined as operating free cash flow after capital, interest, tax, corporate and other expenses), to shareholders at the discretion of the board of directors. Due to the strong group performance and excellent operating free cash flows in FY23, we are pleased to declare a full-year dividend of 75 SA cents (4.03 US cents*) for this reporting period. * The dividend was converted using a closing exchange rate of R18.63/US$1 at 25 August 2023. RESPONSIBLE STEWARDSHIP Health and safety Responsible Stewardship is the first of our four strategic pillars. Safety remains our number one priority and core to our values. FY23 marks seven years since Harmony embarked upon its safety transformation journey. We have made tremendous progress and risk management is now embedded throughout Harmony. We have a centralised operational risk management team providing support to all our operations. Digitisation and modernisation have enabled us to proactively track and monitor leading indicators in real-time through various dashboards. To complement these systems, our humanistic culture transformation programme called Thibakotsi (Sesotho for "prevent accidents"), is well advanced. We are progressing this through continuous employee engagement surveys, visible felt leadership initiatives and leadership development and training. Group LTIFR for FY23 improved to 5.49 per million hours worked compared to 5.65 per million hours worked in FY22. The loss of life injury frequency rate improved to 0.06 per million hours worked in FY23 compared to 0.13 per million hours worked for FY22. MESSAGE FROM THE CHIEF EXECUTIVE OFFICER

 
4 Harmony Gold Mining Company Limited | FY23 Results for the year ended 30 June 2023 Despite these efforts more needs to be done. It is with much sadness and regret that six of our colleagues lost their lives in mine-related accidents during the financial year. We pay our respects and send our heartfelt condolences to the families and loved ones of each of the following colleagues: Juliao Antonio Macamo (stope team leader, Moab Khotsong), Ernesto Euseblo Macuacua (equipping team leader, Tshepong North), Bongile Mcuntula (driller, Kusasalethu), Luyanda Nkwane (underground assistant, Tshepong North), Tshimane Isaac Matabane (stope team member, Kusasalethu) and Matli Bernard Nyama (stope team leader, Kusasalethu). The prevention of work-related illness and mental wellbeing is also of critical importance as we aim to go beyond zero harm. We have a holistic approach to healthcare and proactively manage occupational, non-occupational diseases and the mental health of our employees and host communities. Sustainability and decarbonisation Embedded sustainability is integral to how we operate at Harmony. We are allocating capital to those projects that further our sustainability aspirations. Construction of the first of our four-phase renewable energy programme is now complete and has been commissioned in the Free State. These 30MW solar photovoltaic plants are expected to generate 70 gigawatt hours (Gwh) per annum. Phase 2 of our renewable energy programme is in progress, adding a further 137MW in renewable energy. The first 100MW will be largely funded using the R1.5 billion (US$80 million)* green loan that was secured in June 2022. The remaining 37MW will be delivered through a power purchase agreement. Phase 2 is expected to generate 316Gwh per annum and is expected to be completed in financial year 2025 (FY25). Upon completion, both Phases 1 and 2 will reduce group peak daytime demand by approximately 30%, saving Harmony an estimated R425 million a year in electricity costs. In FY23, 41 energy optimisation projects were implemented resulting in an estimated energy saving of 295Gwh and a cost saving of R394 million (US$22 million). Over 240 energy efficiency projects have been implemented since 2016, cumulatively saving over R1.7 billion (US$114 million) in energy costs to date. At Harmony, we continue to receive positive external recognition for our efforts in sustainability. These include: • inclusion in the FTSE4Good Index for the sixth consecutive year and in the top 5% of the sub-sector • inclusion in the Bloomberg Gender-Equality Index for the fifth consecutive year. This is testimony to how we foster gender diversity and inclusivity, and treat all our employees fairly without bias or prejudice of any kind • a score of ‘A’ from the CDP for our best practice water management strategy • our near-term and longer-term targets have been validated and approved by the Science Based Targets initiative. We have committed to reduce absolute scope 1 and 2 greenhouse gas emissions by 63% by FY36 from a FY21 base year. We are confident of achieving our goal of net zero carbon emissions by 2045. More information is available on our website. Our FY23 ESG and TCFD reports will be published on 25 October 2023. * This amount was converted using the spot exchange rate of R8.83/US$1 in FY23. Operational and financial results for FY23 An exceptional performance from our South African underground mines underpinned our FY23 performance. While the stand-out performer was Mponeng, recognition must be given to each of our operations for their contribution, ensuring we met our production, cost and grade guidance for the financial year. 1. South African underground operations: high-grade Our high-grade mines, Mponeng and Moab Khotsong, had a strong full-year performance driven by a 12% improvement in underground recovered grades to 7.83g/t in FY23 from 7.00g/t in FY22. Production for FY23 increased by 12% to 14 117kg (453 871oz) compared to 12 594kg (404 906oz) in FY22. At Mponeng, underground recovered grades increased by 16% to 8.43g/t in FY23 from 7.25g/t in FY22. This contributed to a 22% increase in gold production at Mponeng for the full year to 7 449kg (239 490oz) from 6 086kg (195 669oz) in FY22. AISC for our high-grade underground operations improved by 2% to R783 311/kg (US$1 371/oz) in FY23 from R801 138/kg (US$1 638/oz) in FY22. Operating free cash flows* from these two mines increased by 172% to R3 448 million (US$194 million) in FY23 from R1 269 million (US$83 million) in FY22, mainly due to the improved recovered grades and the higher average gold price received. Mponeng alone generated R2 139 million (US$120 million) in operating free cash flows during this financial year, representing 35% of the total group's operating free cash flows. The Zaaiplaats project to extend the life of mine at Moab Khotsong is progressing well. Feasibility studies to determine the possibility of deepening Mponeng are also underway and the outcome will be shared at the end of February 2024. * Operating free cash flow = revenue – cash operating cost – capital expenditure as per operating results 2. South African underground operations: optimised# The various optimisation programmes which we implemented across this portfolio are beginning to deliver results including an improvement in profitability and higher operating free cash flows. These operations delivered a good operating performance in FY23. At the end of FY22, a decision was taken to unbundle Tshepong Operations into Tshepong North and Tshepong South. The operations were right-sized to ensure smaller albeit more profitable mines. Bambanani was also closed at the end of FY22 as this mine had reached the end of its commercial life. During our financial year 2024 (FY24) planning cycle, despite depletion during FY23, the life of mine of Masimong remained the same at two years, while Kusasalethu added one year for a three-year life. This is in line with our strategy of unlocking value in our existing operations through brownfield exploration. As expected, production (excluding Bambanani) decreased by 3% to 19 641kg (631 474oz) compared to 20 299kg (652 627oz) in FY22. Average underground recovered grades at these operations, however, improved by 6% to 4.87g/t in FY23 from 4.60g/t in FY22. Operating free cash flows from these operations increased by 463% to R1 115 million (US$63 million) from R198 million (US$13 million) in FY22. AISC for the South African underground optimised operations increased by 11% to R989 249/kg (US$1 732/oz) in FY23 from R888 636/kg (US$1 817/oz) in FY22. This increase was mainly due to flexibility and operational challenges including pillar failure, power failures and ventilation constraints at Target 1. The ongoing recapitalisation project MESSAGE FROM THE CHIEF EXECUTIVE OFFICER continued

 
5 Harmony Gold Mining Company Limited | FY23 Results for the year ended 30 June 2023 MESSAGE FROM THE CHIEF EXECUTIVE OFFICER continued at Target 1 is nearing completion and we anticipate margins and profitability to improve in the second half of FY24 on the back of improved operational performance, efficiencies and costs. Lower-than-planned underground recovered grades at Kusasalethu also contributed towards the higher AISC from the optimised operations. # Optimised operations: Tshepong North, Tshepong South, Doornkop, Kusasalethu, Target 1, Joel, Masimong 3. South African surface operations Tailings retreatment presents a fantastic opportunity for Harmony, given the abundance of resources in old gold tailings dams in the Free State, North West and Gauteng regions. We continue to invest in these low-risk, high-margin operations through our Kareerand tailings storage facility extension at Mine Waste Solutions. Construction is now fully underway following permitting delays. We are also conducting studies to determine the feasibility of converting 5.7 million ounces in Mineral Resources to Mineral Reserves in the Free State region. FY23 production from surface sources decreased by 8% to 7 523kg (241 872oz) from 8 203kg (263 730z) in FY22 as we continue to mine out available rock dumps as planned. South African surface operations' AISC for FY23 increased by 12% to R764 285/kg (US$1 338/oz) compared to R680 841/kg (US$1 392/oz) in the previous reporting period. This was mainly due to above-inflation price increases in consumables, specifically reagents. The surface operations generated operating free cash flows of R835 million (US$47 million) in FY23 compared to R1 380 million (US$91 million) in the previous reporting period. The 39% decline in operating free cash flows was mainly as a result of the R822 million (US$46 million) in major capital deployed at Mine Waste Solutions. 4. International Hidden Valley Gold production in FY23 at Hidden Valley increased by 18% to 4 370kg (140 498oz) from 3 707kg (119 182oz) in FY22. Silver production also increased by 41% to 78 386kg (2 520 163oz) from 55 687kg (1 790 378oz) in FY22. The improved reliability of the overland conveyor belt contributed towards the increase as volumes normalised compared to FY22. However, a slower-than-planned mining rate in the first three quarters negatively impacted gold and silver production. Remedial steps have been implemented to ensure the mining rate normalises in FY24. Recovered grades in FY23 remained largely flat year-on-year at 1.14g/t compared to 1.15g/t in the comparable reporting period. As planned, recovered grades increased by 56% to 1.58g/t in the fourth quarter of FY23 compared to 1.01g/t in the third quarter of FY23. This was as a result of accessing the high-grade areas of the ore body following the waste stripping activities. Cash operating costs were negatively affected by the weaker rand exchange rate, an increase in chemicals and reagents and increased diesel usage for on-site power generation and the mining fleet. The average exchange rate weakened by 17% to R17.76/US$1 in FY23 from R15.21/US$1 in FY22. The prolonged drought in Papua New Guinea has abated and hydroelectric power generation and supply from Papua New Guinea Power Limited has normalised. AISC for FY23 remained steady at R1 014 228/kg (US$1 785/oz) from R1 007 986/kg (US$2 067/oz) due to an improved fourth quarter performance. Hidden Valley generated operating free cash flows of R615 million (US$35 million) in FY23 compared to a negative R46 million (-US$3 million) in FY22. The Hidden Valley extension project, which extends the life of mine to FY28, has commenced and stage 8 stripping activities are underway. Capital expenditure will therefore increase in FY24 as a result of the extension project and the necessary fleet replacement. Wafi-Golpu project On 6 April 2023, Harmony and its Wafi-Golpu Joint Venture partner, Newcrest Mining Limited (Newcrest), signed a non-binding Framework MOU with the Independent State of Papua New Guinea. The MOU represents a significant step forward in progressing towards the signing of a Mining Development Contract for Wafi-Golpu. All parties remain committed to proceeding with the project, subject to finalising the permitting process and approvals of both the Harmony and Newcrest boards. Following the signing of the Framework MOU, Harmony and Newcrest have continued to engage in detailed negotiations with the Papua New Guinea government on the terms of the Mining Development Contract, which is a prerequisite for the granting of a Special Mining Lease. The parties are actively working together to progress these timeously. Eva Copper project Harmony concluded the Eva Copper transaction on 16 December 2022. The purchase price of US$170 million (R2 996 million) was paid using available debt facilities. We are currently updating the feasibility study and will provide a comprehensive update once complete. Currently, we have three drill rigs active on site to further inform the feasibility study outcomes. Over 28 000 metres have been drilled to date. In conjunction with the feasibility study update, we are also engaging with the environmental regulator as it relates to potential permit amendments. These may be required in support of the study outcomes as we are investigating lower carbon intensity power supply options for the project. This is in line with our sustainable development strategy and zero carbon road map. Cost management Cash operating costs in FY23 remained stable, increasing by only 4% to R33 582 million (US$1 890 million) from R32 413 million (US$2 131 million) in FY22. Labour and electricity form the largest component of our cost base. With planning foresight, our cost increases are predictable and controlled. On a per-unit basis, cash operating costs increased by 5% to R735 634/kg (US$1 288/oz) from R701 024/kg (US$1 434/oz) in FY22. Key factors impacting our cash operating costs year-on-year include: • total labour increased by 5% mainly due to salary increases • electricity and water costs increased by 9% mainly as a result of annual tariff increases charged by Eskom • consumables increased by 22% mainly due to the increased cyanide prices, and diesel usage at Hidden Valley • the closure of Bambanani at the end of FY22 reduced costs by R1 157 million (US$76 million) year-on-year. Foreign exchange gains and losses A foreign exchange translation loss of R634 million (US$36 million) was recognised in FY23 compared to a loss of R327 million (US$21 million) in FY22. This was predominantly as a result of the weakening of the rand and the impact this had on US dollar loan balances. The rand weakened

 
6 Harmony Gold Mining Company Limited | FY23 Results for the year ended 30 June 2023 MESSAGE FROM THE CHIEF EXECUTIVE OFFICER continued against the US dollar as evidenced by a closing exchange rate of R18.83/US$1 at 30 June 2023 compared to R16.27/US$1 in the previous reporting period. Taxation A total taxation expense of R1 723 million (US$97 million) was recognised for the group in FY23 compared to a credit of R46 million (US$3 million) in FY22. Current tax increased by 109% to R643 million (US$36 million) from R307 million (US$20 million) mainly due to the increase in production profits at our high-grade underground operations which resulted in higher taxable income. Deferred tax moved from a credit of R353 million (US$23 million) in FY22 to an expense of R1 080 million (US$61 million) in FY23 mainly as a result of the utilisation of unredeemed capital expenditure, higher property, plant and equipment carrying values and increases in the deferred tax rates at Mponeng, Moab Khotsong and a number of our Free State operations. Refer to note 6 in the financial statements. Derivatives and hedging The rand gold price reached all-time highs, above R1 250 000/kg, during the fourth quarter of the financial year, while the US dollar gold price moved above US$2 000/oz in the same quarter. This provided hedging opportunities for the group under the selective hedging approach as defined in our hedging strategy and the gold hedge book was filled up to the 20% limit during the second half of FY23. The average level of hedge cover was at R1 116 000/kg and US$1 990/oz for FY24, and at R1 263 000/kg and US$2 144/oz for FY25. This means the group will be well supported by the hedge book in the event of a downturn in the gold price. Similarly the high volatility and weakening trend of the rand exchange rate afforded the group the opportunity to add to the hedge cover levels on the currency hedging program, also bringing the level of cover to 20% of exposure by financial year-end. The derivative programme moved to a net liability position of R1 152 million (US$61 million) as at 30 June 2023 from a net asset position of R645 million (US$40 million) at FY22. This was mainly due to the increase in the spot gold price and weakening of the rand exchange rate during the financial year. In this reporting period, we recorded a net loss on derivatives of R194 million (US$11 million) compared to a net gain of R53 million (US$3 million) in FY22. The losses on foreign exchange derivatives were also mainly as a result of the weakening of the exchange rate during FY23. Revenue includes a realised hedging loss of R184 million (US$10 million) in FY23 compared to a realised gain of R497 million (US$33 million) in FY22 relating to the realised effective portion of hedge-accounted gold derivatives. Refer to notes 3 and 9 in the financial statements for details on the derivative programme. FY24 GROUP GUIDANCE FY24 production guidance for the group is between 1 380 000 ounces to 1 480 000 ounces at an AISC of less than R975 000/kg. Underground recovered grade for FY24 is guided at between 5.60g/t to 5.75g/t. Refer to Assumptions in the Summary update of our Mineral Resources and Mineral Reserves on page 9 for further detail. Also refer to our forward-looking statements on page 2 in this regard. Capital expenditure in FY24 is expected to increase to R9 500 million (US$535 million) mainly as a result of our investment in our major projects, necessary fleet replacement at Hidden Valley due to the life of mine extension project, and an increase in ongoing development capital. We are currently updating the Eva Copper feasibility study. Upon completion, we will provide an updated guidance on the project development costs and funding structure. LOOKING AHEAD We are global leaders in underground narrow-reef gold mining and remain a bastion of excellence and partner of choice wherever we operate. Our exciting and comprehensive growth pipeline includes two significant copper projects which will transform Harmony into a global gold-copper producer. Creating long-term value for all our shareholders and stakeholders is the cornerstone of how we operate. As we embark on the next phase of our growth journey, successfully executing on our four strategic pillars of responsible stewardship, operational excellence, cash certainty and effective capital allocation, remains of utmost importance. It is for this reason that we nurture and develop world-class talent. Harmony embraces diversity and inclusion, evident throughout our operations. Our people remain our number one asset and we are supported by highly experienced teams to secure our future and success. At Harmony, we choose actions over words. Protecting our planet, caring for our people and conducting ethical mining is embedded in how we operate. Delivering on our promises whilst leaving a positive lasting legacy is Mining with Purpose.

9 Harmony Gold Mining Company Limited | FY23 Results for the year ended 30 June 2023 Harmony’s statement of Mineral Resources and Mineral Reserves as at 30 June 2023 is produced in accordance with the South African Code for the Reporting of Exploration Results, Mineral Resources and Mineral Reserves (SAMREC). It should be noted that the Mineral Resources are reported inclusive of the Mineral Reserves. In our Form 20-F the Mineral Resources are reported exclusive of reserves. United States investors are urged to consider the disclosure in this regard in our Form 20-F which will be available on our website at www.harmony.co.za/invest/annual-reports on 31 October 2023. This report provides a summary of the update, while the detailed statement of the Mineral Resources and Mineral Reserves will be published in the Integrated Annual Report on 25 October 2023, which will be available at www.harmony.co.za/invest. Refer to the website (www.harmony.co.za) for the updated reserves and resources tables as at 30 June 2023. SUMMARY UPDATE OF HARMONY’S MINERAL RESOURCES AND MINERAL RESERVES South African surface operations, including Kalgold The company’s Mineral Resources at the South African surface operations as at 30 June 2023 are 14.0Moz (1 584.5Mt at 0.27g/t), a decrease of 4% mainly due to the reduction of Mineral Resources from the Kalgold operation. The company’s Mineral Reserves after normal depletion at the South African surface operations as at 30 June 2023 are 9.7Moz (1 174.1Mt at 0.26g/t) a decrease of 7% mainly due to the reduction of Mineral Reserves at the Kalgold operation as result of the change in the life of mine strategy. Papua New Guinea Papua New Guinea operations The company’s attributable gold and gold equivalent Mineral Resources at the Papua New Guinea operations as at 30 June 2023 are 39.3Moz, an increase of 4% year-on-year from the 37.9Moz declared as at 30 June 2022. This increase is mainly as a result of the increase in gold equivalents due to commodity price changes. The company’s gold and gold equivalent Mineral Reserves at the Papua New Guinea operations as at 30 June 2023 are 19.2Moz, an increase of 5% year-on-year from the 18.2Moz declared as at 30 June 2022. The increase is mainly as a result of the increase in gold equivalent due to commodity price changes. Australia Australian operations The company’s gold and gold equivalent Mineral Resources at the Australian operations as at 30 June 2023 are 8.1Moz. The company’s gold and gold equivalent Mineral Reserves at the Australian operations will be declared once the feasibility study is concluded. INTRODUCTION Harmony’s strategy is to produce safe, profitable ounces and increase margins. This includes delivering safely on our operational plans, reducing costs and improving productivity. Harmony’s growth journey entails acquiring quality assets. In FY17, Harmony invested in the life-of-mine extension at Hidden Valley and in FY18 acquired and integrated the higher-grade Moab Khotsong operations. In FY21, Harmony acquired the remainder of the AngloGold Ashanti South African assets – Mponeng and related assets. In FY22, Harmony acquired the low-risk Eva Copper project and surrounding exploration tenements from Copper Mountain Mining Corporation. HARMONY – TOTAL The company’s attributable gold and gold equivalent Mineral Resources are declared as 137.8Moz as at 30 June 2023, a 4% increase year-on-year from the 132.6Moz declared as at 30 June 2022. The total gold contained in the Mineral Resources at the South African operations represents 66% of the company total, with the Papua New Guinea operations representing 28% and Australian operations 6% of Harmony’s total gold and gold equivalent Mineral Resources as at 30 June 2023. Harmony’s attributable gold and gold equivalent Mineral Reserves amount to 39.3Moz, a 1% decrease from the 39.8Moz declared at 30 June 2022. The gold reserve ounces in South Africa represent 51%, while the Papua New Guinea gold and gold equivalent ounces represent 49% of Harmony’s total Mineral Reserves as at 30 June 2023. The Australian gold and gold equivalent ounces will be declared once the feasibility study is concluded. South Africa South African underground operations The company’s Mineral Resources at the South African underground operations as at 30 June 2023 are 76.4Moz (237.4Mt at 10.01g/t), a decrease of 5% year-on-year from the 80.1Moz (249.4Mt at 9.99g/t) declared as at 30 June 2022. This decrease is mainly due to normal depletion and a reduction in Mineral Resources at the Joel, Phakisa and Moab Khotsong operations as result of geological model changes. The company’s Mineral Reserves at the South African underground operations as at 30 June 2023 are 10.4Moz (50.0Mt at 6.50g/t), a decrease of 6% year-on-year from the 11.1Moz (54.0Mt at 6.40g/t) declared as at 30 June 2022. The decrease in ounces is mainly due to normal depletion and the Mineral Reserves reduction as result of geological models changes. ASSUMPTIONS In converting the Mineral Resources to Mineral Reserves, the following commodity prices and exchange rates were applied: • A gold price of US$1 582/oz • An exchange rate of R16.22/US$ • The above parameters resulted in a Rand/kg gold price of R825 000/kg for the South African assets • The Hidden Valley mine and the Wafi-Golpu project used commodity prices of US$1 582/oz Au, US$22.35/oz Ag and US$3.70/lb Cu at an exchange rate of AUD1.43 per US$ • Gold equivalent ounces are calculated assuming US$1 582/oz Au, US$3.70/lb Cu and US$22.35/oz Ag, and assuming a 100% recovery for all metals.

12 Harmony Gold Mining Company Limited | FY23 Results for the year ended 30 June 2023 EXPLORATION Our exploration strategy is to predominantly pursue brownfields exploration targets close to existing infrastructure. This will drive short to medium-term organic ore reserve replacement and growth to support our current strategy of increasing quality ounces and mitigate the risk of a depleting ore reserve base. Key workstreams underpinning the FY23 exploration programme include: • exploration at Eva Copper • brownfield exploration at Hidden Valley, Kerimenge and Kalgold to optimise existing open pit operations and extend mine life • brownfield exploration at our underground operations in South Africa • greenfield exploration at Target North • reviewing exploration opportunities as part of our new business strategy. A detailed report of the Exploration Results will be provided as part of the suite of annual reports to be published on 25 October 2023.

SUMMARY UPDATE OF HARMONY’S MINERAL RESOURCES AND MINERAL RESERVES continued Mineral Reserves: Silver and copper (used in equivalent calculations) Proved Probable Total Tonnes (Mt) Grade (g/t) Silver (000oz) Tonnes (Mt) Grade (g/t) Silver (000oz) Tonnes (Mt) Grade (g/t) Silver (000oz) Hidden Valley 1.6 21.20 1 109 17.6 27.82 15 744 19.2 27.26 16 853 Proved Probable Total Tonnes (Mt) Grade (%) Copper (Mlb) Tonnes (Mt) Grade (%) Copper (Mlb) Tonnes (Mt) Grade (%) Copper (Mlb) Golpu* — — — 200.0 1.20 5 400 200.0 1.20 5 400 * Represents Harmony’s equity portion of 50% ** In instances where individual deposits may contain multiple valuable commodities with a reasonable expectation of being recovered (for example gold and copper in a single deposit), Harmony computes a gold equivalent to more easily assess the value of the deposit against gold-only mines. Harmony does this by calculating the value of each of the deposits' commodities, then dividing the product by the price of gold. For example, the gold equivalent ounces for the copper portion of a deposit would be calculated as follows: (copper pounds x copper price per pound)/gold price per ounce. All gold equivalent calculations are done using metal prices and parameters as stipulated above Note: Rounding of numbers may result in slight computational discrepancies

Harmony Gold Mining Company Limited | FY23 Results for the year ended 30 June 202322 NOTES TO THE CONDENSED CONSOLIDATED FINANCIAL STATEMENTS FOR THE YEAR ENDED 30 JUNE 2023 (RAND) 1. ACCOUNTING POLICIES Basis of accounting The condensed consolidated financial statements for the year ended 30 June 2023 have been prepared in accordance with the JSE Limited Listings Requirements and the requirements of the Companies Act no. 71 of 2008 of South Africa. The 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) as issued by the International Accounting Standards Board (IASB), South African financial reporting requirements and to also, as a minimum, contain the information required by IAS 34 Interim Financial Reporting. The accounting policies applied in the preparation of the condensed consolidated financial statements are in terms of IFRS and are consistent with those applied in the previous consolidated annual financial statements, with the exception of the new accounting policy for toll treatment services (refer note 3). 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 on a going concern basis. During the year ended 30 June 2023, the Tshepong Operations were reported on as two separate reportable segments, namely Tshepong North and Tshepong South, following the restructuring of the Tshepong Operations in the 2022 financial year. In accordance with the requirements of IFRS, the prior year comparative information has been re-presented in the segment report. 2. IMPACT OF CHANGES IN GLOBAL OPERATING AND ECONOMIC ENVIRONMENT Covid-19 Although the disruption caused by Covid-19 has diminished significantly worldwide, Harmony still maintains a precautionary approach to infectious disease control. Harmony is actively monitoring and managing the supply of critical items to ensure that production is not affected, thereby ensuring the company remains in a position to manage Covid-19 as part of normal day-to-day activities. Cost and inflationary pressures During the 2023 financial year, Harmony continued to experience heightened input costs driven by inflationary pressures. The effect has been especially pronounced on certain key items such as oil (directly affecting diesel supply and cost), electricity and certain chemical reagents used by treatment plants. Refer to note 4. The announcement by the energy regulator in South Africa, NERSA, of a 18.65% tariff hike in electricity is incorporated into the 2023/2024 budgeting and forecasting process. This brings further impetus to Harmony's renewable energy programme. Interest rates Over the past year, central banks globally have been increasing interest rates as a measure of combating rising inflation. In the current financial year, the US Federal Reserve (US Fed) raised interest rates by 350 basis points, while the South African Reserve Bank (SARB) similarly raised the repurchase interest rate by 350 basis points. This contributed to increased finance costs and investment income for the 2023 financial year (refer to note 5). The increase in interest rates also contributed to higher bond yields in the market, which affected the risk-free rates used for discounting of the provision for environmental rehabilitation (refer to note 11) and the provision for silicosis settlement (refer to note 12). Commodity prices and exchange rates Gold traded within a range of US$1 622/oz and US$2 051/oz (2022: US$1 726/oz and US$2 052/oz) during the current financial year, reaffirming its safe haven status with investors during times of global uncertainty and market volatility. These uncertainties have also resulted in increased volatility in the R/US$ and R/A$ exchange rates. The currencies traded in ranges of R16.17/US$1 to R19.81/US$1 (2022: R14.15/US$1 to R16.30/US$1) and R11.19/A$1 to R12.94/A$1 (2022: R10.43/A$1 to R11.63/A$1) during the current financial year. These movements in the currencies expose the group's operations to foreign currency gains and losses on foreign-denominated receivables and liabilities, including derivatives, and also impact the group’s translation of its international operating results and net assets into its Rand presentation currency, which resulted in a foreign exchange translation gain of R1.1 billion for the 2023 year (2022: R742 million). As part of the underlying assumptions used in valuing certain line items, management used a consensus of market analysts’ forecasts in determining short-, medium- and long-term commodity prices and exchange rates. These economic assumptions are used in certain fair value calculations. Based on the consensus forecasts used, a marked increase was seen in US$ gold price and R/US$ exchange rate assumptions applied. Refer to note 8 for disclosed assumptions.

REVENUE Accounting policy - toll treatment services The group has entered into agreements with various third parties to treat gold-bearing material at certain of the group's metallurgical plants. The determination of the consideration receivable is set out in each individual contract, based on the third parties' specific circumstances. Revenue from toll treatment services is recognised as the group satisfies its performance obligation under its contract with the third parties, which is the recovery of the gold through the treatment process and the facilitation of the ultimate sale of recovered gold. This is satisfied over time. Settlement is done in the month following the sale of gold (see below). Subsequent to treatment, the group delivers the recovered gold on behalf of the third parties to the refinery for further refining, whereafter it is sold. The group acts as an agent in the sales process, receiving payment on behalf of the third parties before transferring the amounts owed to them.

This resulted in an increase in the average gold spot price received by 17.3%, from R883 453/kg in the 2022 year to R1 036 682/kg. The increase in revenue was partially offset by the closure of Bambanani in June 2022, which contributed revenue of R1 286 million in 2022. 2 Silver is derived from the Hidden Valley mine in Papua New Guinea. The increase in silver revenue in the 2023 financial year is mainly due to an increase in production of 38% to 82 093kg from 59 489kg in 2022. In addition, the average silver price increased by 10.7% from R11 293/kg in the 2022 year to R12 505/kg. 3 Uranium is derived from the Moab Khotsong operation. 4 Relates to the recognition of non-cash consideration recognised as part of revenue for the streaming arrangement. Refer to note 14 for further information. 5 Relates to services rendered for the treatment of third-party gold-bearing material at certain South African operations. During the 2023 financial year additional contracts were entered into, which increased the amounts recognised significantly. As a result, the service fees have been included as a separate revenue stream for 2023, with the associated costs included in Cost of Sales. The amount for the 2022 year was not significant and therefore it has not been reclassified from other operating income/expenses where it was previously recognised, along with the associated costs. 6 Relates to the realised effective portion of the hedge-accounted gold derivatives. The average gold market spot price during the 2023 financial year was R1 045 527/kg (2022: R896 712/kg) compared to the average forward price of matured contracts of R1 028 764/kg (2022: R940 536/kg) . Refer to note 9 for further information. 7 A geographical analysis of revenue is provided in the segment report. 1 Production costs increased during the 2023 year, mainly due to inflationary pressures on costs including labour, electricity and consumables costs (refer to note 2). The increase in production costs was offset by the closure of Bambanani on 30 June 2022. 2 The royalty tax increased due to a higher rate being applied due to higher profits, as well as the increased revenue base to which it is applied. 3 No impairments or reversal of impairments of assets were recognised during the 2023 financial year. Refer to note 8 for further details. 4 The increase is attributable to the voluntary severance packages that were taken up following the disaggregation of the Tshepong Operations into Tshepong North and Tshepong South. The bulk of the employees from these operations have been accommodated at other operations within the group. 5 Relates to costs associated with services rendered for the treatment of third-party gold-bearing material. Refer to note 3 for further detail.

OTHER INCOME STATEMENT ITEMS Investment income Investment income for the current financial year increased mainly due to higher interest rates, which resulted in an increase of R149 million interest received on cash balances and restricted cash and investments year on year. Refer to note 2 for a discussion thereof. Additionally, a fair value gain of R167 million was recognised on restricted cash and investments. Finance costs Finance costs for the current financial year increased mainly due to increased US$ loan balances and higher interest rates compared to the prior year. This resulted in an elevated interest expense of R228 million. Refer to note 2 and 13 for details. 6. TAXATION Current taxation The increased current tax expense is mainly attributable to mining taxes recognised by Golden Core Trade and Invest (Pty) Ltd (Golden Core) of R272 million (2022: Rnil) and Harmony Moab Khotsong Operations (Pty) Ltd (Moab Khotsong) of R260 million (2022: R130 million). The higher gold prices and production led to increased taxable income for the two entities. The expense in Golden Core was offset by the utilisation of its remaining unredeemed capital expenditure balance of R845 million. Due to the changes announced in the 2022 budget speech, the corporate tax rate applied to non-mining taxable income has been amended to 27% (2022: 28%) with the mining tax rate moving from 34% in 2022 to 33% for the current year. Further, the annual limitation of assessed loss utilisation to 80% of taxable income came into effect. Deferred taxation The movement in the net deferred tax liability is mainly attributable to an increase in net taxable temporary differences as well as in deferred tax rates for the majority of the group's South African mining companies. The amount recognised at 30 June 2023 is as follows: At Figures in million 30 June 2023 (Reviewed) 30 June 2022 (Audited) Balance at beginning of year 1 383 1 906 Expense/(credit) per income statement (a) 1 080 (353) Tax expense/(credit) directly charged to other comprehensive income (b) (358) (170) Balance at end of year 2 105 1 383 Deferred tax asset per balance sheet (c) (189) (203) Deferred tax liability per balance sheet 2 294 1 586 (a) The main contributors to the increases were: • The change in Freegold (Harmony) Pty Ltd's deferred tax rate from 7.0% to 11.4% resulted in a R172 million increase in the deferred tax liability. This, together with the full utilisation of its unredeemed capital expenditure balance and increase in the carrying amount of property, plant and equipment during 2023, resulted in an overall R305 million increase in the net deferred tax liability • Moab Khotsong's deferred tax rate changed from 14.7% to 16.7%, causing a R77 million increase in the net deferred tax liability. In addition, higher capital expenditure for the year, which includes the Zaaiplaats project, resulted in an overall R201 million increase in the net deferred tax liability • Golden Core fully utilised its unredeemed capital expenditure balance, which combined with the R144 million impact of a higher deferred tax rate of 17.7% (2022: 12.8%), resulted in an overall R310 million increase in the net deferred tax liability for 2023 • Chemwes (Pty) Ltd's capital expenditure spend relating to the Kareerand expansion project and the decrease in Franco-Nevada liability (refer to note 14) resulted in a change of R96 million from a net deferred tax asset to the net deferred tax liability position at 30 June 2023. (b) The movement in the net derivative position (refer to note 9) resulted in a decrease of R359 million in the net deferred tax liability. (c) As at 30 June 2023 a deferred tax asset was recognised in Harmony Gold Mining Company Limited (Harmony Company). The deferred tax asset for Harmony Company increased slightly to R189 million. 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. Refer to note 15 for the assessment made regarding Eva Copper's deferred tax asset.

PROPERTY, PLANT AND EQUIPMENT Additions to property, plant and equipment Refer to note 15 and 17 for property, plant and equipment acquired and capital expenditure, respectively, during the year ended 30 June 2023. Stripping activities and foreign exchange impact Costs capitalised relating to stripping activities for the year ended 30 June 2023 amounted to R1 514 million with Hidden Valley accounting for R1 330 million of these costs. The foreign exchange translation movement on property, plant and equipment increased by R958 million for the year ended 30 June 2023. Impairment of property, plant and equipment At 30 June 2023, management performed an assessment for indicators of impairment as well as indicators of 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 current financial year. The Target 1, Kalgold and Kusasalethu CGUs experienced operational issues during the year ended 30 June 2023. These operational issues were considered to be indicators of potential impairment and therefore an impairment assessment was performed for these CGUs. For the 2022 financial year, as a result of the group net asset value exceeding Harmony's market capitalisation as at 30 June 2022, impairment assessments were performed for all CGUs. The recoverable amounts for these CGUs were determined on a fair value less cost to sell basis using assumptions in the discounted cash flow models and attributable resource values. These are fair value measurements classified as level 3. Critical accounting estimates and judgements The recoverable amount of mining assets is determined utilising real discounted future cash flows. In determining the commodity prices and exchange rates assumptions to be used, management assesses the short-, medium- and long-term views of several reputable institutions. The long-term price was determined as part of the annual budgeting process and is used in the life-of-mine plans and is also the cut-off price for calculating reserves included in the declaration of resources and reserves in terms of the South African Code for the Reporting of Exploration Results, Mineral Resources and Mineral Reserves (SAMREC). 1 Includes an amount of R333 million related to the impairment of goodwill in 2022 which does not have a tax effect.

PROPERTY, PLANT AND EQUIPMENT continued Impairment of property, plant and equipment continued Critical accounting estimates and judgements continued Post-tax real discount rates ranging between 11.7% and 13.2% (2022: 10.2% and 13.1%), depending on the CGU, were used to determine the recoverable amounts for the CGUs tested for impairment. The commodity price and exchange rate assumptions used in the impairment assessments are as follows: Year ended 30 June 2023 (Reviewed) 30 June 2022 (Audited) US$ gold price per ounce – Year 1 1 932 1 861 – Year 2 1 844 1 744 – Year 3 1 725 1 664 – Long term (year 4 onwards) 1 582 1 546 Exchange rate (R/US$) – Year 1 18.28 15.55 – Year 2 17.44 15.34 – Year 3 17.13 15.26 – Long term (Year 4 onwards) 16.22 15.35 Rand gold price (R/kg) – Year 1 1 135 000 931 000 – Year 2 1 034 000 860 000 – Year 3 950 000 816 000 – Long term (year 4 onwards) 825 000 763 000 US$ copper price per pound 3.70 3.30 Exchange rate (PGK/US$) 3.51 3.50 US$ silver price per ounce – Year 1 23.71 23.85 – Year 2 22.75 22.42 – Year 3 21.78 21.46 – Long term (year 4 onwards) 20.86 19.38 Included in the discounted cash flow models used for determining recoverable amounts of the respective CGUs, management incorporated the estimated production cost and carbon tax savings arising from the rollout of Harmony's renewable energy programme, as part of its greater decarbonisation strategy. Results of impairment and assessment Based on the impairment tests performed, no impairments were recorded for the 2023 financial year. For the 2022 financial year the following impairments were recognised: • Tshepong North: R2 296 million as a result of inflationary pressures on capital and working costs, the reclassification of the sub-75 decline project from reserves in the life-of-mine plan to the resource base and an increased post-tax discount rate of 11.7% • Tshepong South: R1 326 million as a result of inflationary pressures on capital and working costs, additional capital expenditure to address flexibility constraints and an increased post-tax discount rate of 11.7% • Moab Khotsong: R522 million as a result of inflationary pressures on capital and working costs, additional capital expenditure for the Zaaiplaats project and an increased post-tax discount rate of 10.4% • Kusasalethu: R145 million as a result of decreased gold production in the life-of-mine plan for the operation • Bambanani: R144 million as a result of the revision of the operation's life-of-mine plan following increased seismicity being experienced at the operation. Where CGUs had previously been impaired, management considered whether the impairment loss (or the contributors to the previously recognised impairment loss) no longer exists or might have decreased. Management considered general and specific factors for each CGU and concluded that although overall the gold price had improved from the time that the impairment losses had been recognised, the specific circumstances that led to the original impairments had not reversed. Furthermore, the service potential of the asset has not increased. Management therefore deemed it appropriate for no reversal of previously recognised impairment losses to be recorded for the year ended 30 June 2023.

PROPERTY, PLANT AND EQUIPMENT continued Impairment of property, plant and equipment continued Sensitivity analysis One of the most significant assumptions that influence the life-of-mine plans, and therefore impairment assessments, is the expected commodity prices. Management determined a reasonably possible change of 11.8% in gold prices based on the standard deviation of market analysts' forecasted long-term gold price assumptions. A 11.8% decrease in the gold price assumptions (with all other variables held constant) would have resulted in the following post-tax impairment being recorded as at 30 June 2023: Figures in million 30 June 2023 (Reviewed) 11.8% decrease Target 1 1 719 Kusasalethu — Kalgold 475 9.

OTHER ASSETS Restricted cash and investments The balance at 30 June 2023 increased by R580 million, comprising an increase of R156 million in restricted cash and R424 million in restricted investments. Interest received on investments (R246 million) increased year on year due to higher interest rates in 2023. The remainder is mainly due to the mark-to-market valuation of these trust funds. Refer to note 2 for a discussion on interest rates. Inventories The increase in inventories during the 2023 financial year of R447 million is mainly due to the increase in consumables at Hidden Valley, predominantly diesel, as a result of higher volumes held to support the increased production. This was coupled with the weakening of the Rand/A$ exchange rate, further increasing the translated balance year on year for South-east Asia. Trade and other receivables The balance at 30 June 2023 increased by R713 million, mainly due to an increase in the gold debtor of R515 million as a result of the timing of receipts. 11. PROVISION FOR ENVIRONMENTAL REHABILITATION The increase in the provision during the 2023 financial year of R460 million is mainly due to the time value of money unwind of R483 million, offset by the utilisation of the provision of R120 million and the change in estimate of R78 million relating to higher discount rates. Also contributing to the increase is the effect of the translation of the balance for South-east Asia of R173 million. Refer to note 2 for a discussion of the impact of interest rates on the discount rates, as well as for further detail on the exchange rate changes. 12. OTHER LIABILITIES Other provisions The decrease year on year is due to a decrease in the provision for silicosis settlement of R271 million as a result of increased discount rates and payments of R155 million made to the Tshiamiso Trust during the year.

OTHER LIABILITIES continued Trade and other payables The balance at 30 June 2023 increased by R744 million. The increase in certain cost categories contributed to the change year on year - refer to note 2 and 4. Also contributing are amounts received on behalf of third parties in terms of toll treatment agreements increasing by R195 million. Additionally, income tax payable as at 30 June 2023 increased by R157 million (see note 6 for discussion). 13.

A further 12 month extension is available and is not taken into account. 3 Ten equal bi-annual instalments starting from June 2024 with the final instalment on maturity. The Green loan can only be used for eligible renewable energy projects defined in the agreement. The Rand RCF, US$ RCF and US$ term loan are linked to certain sustainability-linked key performance indicators (ESG KPIs), which will be measured annually for the current financial year as well as the next two and will result in changes to interest rate margins. The rate will be adjusted annually by one basis point for each metric achieved (decrease) or not (increase), with these adjustments being cumulative over the three-year measuring period. The adjustments to interest rate margins for each financial year's ESG performance would impact the following financial year. The respective ESG KPIs are as follows: KPI Unit of Measurement Scope Sustainability performance targets FY23 Targets FY24 Targets FY25 Targets Greenhouse gas emissions ‘000 tonnes of Scope 1 and Scope 2 CO2e emissions All operations 4 485 4 279 4 074 Renewable energy Renewable energy consumption as % of total electricity consumed SA operations 2% 8% 20% Water consumption Potable water consumed (Ml) SA operations 20 453 19 833 19 436 Based on the 2023 performance, the interest rates of the related loans will be adjusted accordingly for the 2024 financial year. Debt covenants 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. Debt covenant tests were performed for the loan facilities for the 2023 and 2022 financial years and no breaches were noted. For the 2023 financial year, the group's interest cover ratio was 26 times (2022: 43.4 times) while the group's leverage was 0.2 (2022: 0.1). 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.

Harmony Gold Mining Company Limited | FY23 Results for the year ended 30 June 202332 NOTES TO THE CONDENSED CONSOLIDATED FINANCIAL STATEMENTS continued FOR THE YEAR ENDED 30 JUNE 2023 (RAND) 15 ACQUISITIONS AND BUSINESS COMBINATIONS ACQUISITION OF EVA COPPER On 6 October 2022, Harmony announced that it had entered into an agreement to acquire the entity which owns 100% of the Eva Copper project and a package of regional exploration tenements from Copper Mountain Mining Corporation (collectively Eva Copper). The acquisition is in line with the group's strategic objective of transitioning into a low-cost gold and copper mining company. Diversifying into copper enables Harmony to participate in the global transition to a low-carbon economy. The last condition precedent for the acquisition was fulfilled during December 2022, resulting in an acquisition date of 16 December 2022. Based on management's assessment, the transaction met the definition of a business combination as defined by IFRS 3 Business Combinations. This is based on the feasibility study, mine development plan and organised workforce acquired constituting substantive processes which significantly contributes to the ability to generate outputs. Management also opted to not apply the optional concentration test as per IFRS 3. The Eva Copper project was identified as a cash generating unit (CGU). Consideration transferred Consideration for the transaction amounted to a cash payment of R2 996 million (US$170 million), paid during December 2022, and contingent consideration subject to the following criteria: • A maximum of US$30 million payable via a 10% sharing of net incremental revenue above US$3.80/Ib Cu (excess payment) • A maximum US$30 million payable on a new copper resource discovered and declared within the acquired tenements, calculated using a resource multiple of US$0.03/Ib Cu (new resource payment). These criteria are applicable for the entire life of the operation until the maximum payments are reached. As at 16 December 2022, the contingent consideration was valued at R169 million by 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 12.9%. All other assumptions applied in the valuation are consistent with those used in the valuation of identified assets acquired and liabilities assumed (refer below). The fair value calculated for the contingent consideration is level 3 in the fair value hierarchy due to the use of unobservable inputs. The remeasurement of the liability will be included in other operating expenses. Refer to note 16 for the measurement of the liability at 30 June 2023. The amount disclosed in the cash flow statement for cash paid for the acquisition of Eva Copper is equal to the cash consideration paid of R2 996 million. Acquisition-related costs The total of R214 million for acquisition-related costs for the year ended 30 June 2023 relates to various costs directly attributable to the acquisition process. These costs include professional services fees and Australian stamp duty costs paid. Identifiable assets acquired and liabilities assumed For the period ended 31 December 2022 the fair value exercise, also known as the purchase price allocation, was prepared on a provisional basis in accordance with IFRS 3. During the measurement period, being 12 months permitted in terms of IFRS 3 for completion of the fair value exercise, Harmony concluded the process of determining the effective tax values for assets acquired and liabilities assumed from the business combination. This resulted in a change in the value of deferred tax and property, plant and equipment. Harmony also received additional information relating to trade and other receivables that existed at acquisition date. No other key valuation assumptions were revised. Management considers the revised purchase price allocation to be final and the accounting for the acquisition to be concluded as at 30 June 2023. The final amounts for the identifiable assets acquired and liabilities assumed have been included below. Critical accounting estimates and judgements The fair value of the identifiable net assets acquired was determined using the expected discounted cash flows based on the feasibility study of the Eva Copper project. Key assumptions for the level 3 fair value measurement of Eva Copper are the copper price, marketable discount rates, exchange rates and the feasibility study previously performed for the Eva Copper project. Mineral resource acquired which were not included in the discounted cash flows were valued using a copper resource multiple price of US$0.03/lbs. The post-tax real discount rate used was 10.7%, the long-term A$/US$ exchange rate used was A$1.40/US$1 and a real long-term copper price of US$3.50/lbs was used. The valuation was performed as at 16 December 2022. 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 16 December 2022 was 30%. Following the finalisation of the effective tax values of assets acquired and liabilities assumed from the acquisition, a net deferred tax asset position of R224 million was determined. In line with IAS 12 Income Taxes, management assessed that at the acquisition date it was not yet probable that sufficient future taxable profits will be generated from Eva Copper against which the net deferred tax asset could be recognised. It was therefore opted to not recognise the net deferred tax asset position arising from the acquisition.

Performance of acquired operation Immaterial costs were incurred for Eva Copper relating to the year ended 30 June 2023 and therefore no proforma information has been disclosed. 16. FINANCIAL RISK MANAGEMENT ACTIVITIES Foreign exchange risk Harmony's revenues are sensitive to the R/US$ exchange rate as all revenues are generated by gold sales 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 weakened during the 2023 year by 15.7%, from a closing rate of R16.27/US$1 on 30 June 2022 to R18.83/US$1 on 30 June 2023. The volatility in the exchange rate is driven by global economic factors. Refer to note 2 for a discussion on some of the factors and their impact. The weakening negatively impacted on the derivative valuations as well as the translation of the US$ debt facilities at 30 June 2023. Refer to note 13 for detail. During the 2023 year the Rand weakened by 11.6%, from a closing rate of R11.25/A$1 on 30 June 2022 to R12.56/A$1 on 30 June 2023. This impacted on the translation of balances from Australian dollar to Rand on consolidation as well as the average rate at which income statement items were translated at. These changes resulted in a foreign exchange translation gain of R1 123 million for the 2023 year. 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, and in the case of Hidden Valley, silver as well. Harmony entered 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. The general limit for gold hedging currently set by the Board is 20% for a 24-month period. The limit set by the Board is 50% of silver exposure over a 24-month period. 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 spot gold prices during the 2023 year mainly exceeded the average locked in prices on the rand gold hedging contracts. This has resulted in a negative impact on the contracts that matured during the period as well as those that are outstanding at the reporting dates. Refer to note 2 for a discussion on the impact of commodity prices and exchange rates. Interest rate risk During the 2023 year the US Fed and SARB increased interest rates by 350 basis points. The higher interest rates together with the increased borrowings, led to an unfavourable impact on the group's cost of debt. However, the increased interest rates had a positive effect on the investment income earned on cash balances and restricted cash and investments. Although higher interest rates along with increased debt levels had an unfavourable impact on the group's finance costs for the 2023 year, the group has not entered into interest rate swap agreements as the interest rate risk continues to be assessed as low. The audit and risk committee reviews the group's risk exposure quarterly.

FINANCIAL RISK MANAGEMENT ACTIVITIES continued Credit risk 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 30 June 2023, the rating of major SA 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 costs at 30 June 2023 resulted in an immaterial amount for each instrument. The credit rating of the group's Australian counterparts remained unchanged at A+ resulting in the assessed ECL remaining 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. Capital risk management The consideration of R2 996 million for the acquisition of Eva Copper is the main contributor to the group's increased net debt compared to 30 June 2022. It remains the group's objective to adhere to a conservative approach to debt and maintain low levels of gearing. Net debt is as follows: At Figures in million 30 June 2023 (Reviewed) 30 June 2022 (Audited) Cash and cash equivalents 2 867 2 448 Borrowings (5 695) (3 205) Net debt (2 828) (757) 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 or indirectly (that is, as prices) or indirectly (that is derived from prices) Level 3: Inputs for the asset that are not based on observable market data (that is unobservable inputs).

The fair value of the investment 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 as at 30 June 2023. 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. (b) 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 level 1 valued assets comprise of listed equity securities designated as fair value through other comprehensive income instruments. The remaining balance of the environmental trust funds is carried at amortised cost and therefore not disclosed here.

FINANCIAL RISK MANAGEMENT ACTIVITIES continued Fair value determination continued (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 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 contracts (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 contracts (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 • 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. (d) At 30 June 2023, the fair value movement was calculated using a discounted cash flow model, taking into account forecasted dividend payments over the estimated repayment period of the loan at a rate of 12.7% (2022: 9.3%). A 37 basis points (2022: 99 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 balance sheet. In the 2023 year, repayments to the value of R74 million (2022: R65 million) were received. (e) Contingent consideration liabilities consist of the following: • Mponeng operation The consideration for the Mponeng operation and related assets included a contingent consideration determined using the expected gold production profile for Mponeng. At 30 June 2023, the liability was valued at R404 million (2022: R356 million) at a post-tax real rate of 9.6% (2022: 10.2%). Should the expected gold production profile increase by 9.8% or decrease by 9.8%, the contingent consideration liability would increase by R411 million (2022: R251 million at 7.6%) or decrease by R314 million (2022: R189 million at 7.6%), respectively. This represents reasonably possible changes which were determined based on the standard deviation of previous years' production of the Mponeng operation. No other reasonably possible 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 R185 million at 30 June 2023. Refer to note 15 for further information. There are no inputs to the valuation that a reasonably possible change would result in a material change in the fair value of the 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 fair values of borrowings are not materially different to their carrying amounts since the interest payable on those borrowings is at floating interest rates. 17. ADDITIONAL CASH FLOW DISCLOSURES Cash generated by operations increased year on year primarily due to a higher revenue earned. Refer to note 3 for further detail. The increase was offset by the increase in operational costs such as production costs, employment and restructuring costs, exploration expenditure as well as the acquisition-related costs of the Eva Copper project. Refer to note 4, 5 and 15 respectively for further detail.

RELATED PARTIES The following directors and prescribed officers owned shares in Harmony at year end. The balance of shares held is attributable to shares held privately and in terms of the minimum shareholding requirement as set out in our remuneration policy: At Name of director/prescribed officer 30 June 2023 (Reviewed) 30 June 2022 (Audited) PW Steenkamp (Executive director) 598 513 772 589 BP Lekubo (Executive director) 24 753 15 988 HE Mashego (Executive director) 28 975 14 875 BB Nel (Prescribed officer) 54 195 110 207 MP van der Walt (Prescribed officer) 66 870 100 000 JJ van Heerden (Prescribed officer) 42 310 30 734 M Naidoo-Vermaak (Prescribed officer) 7 966 7 966 On 29 November 2022, Harmony announced the retirement by rotation of Mr Andre Wilkens, non-executive director, and Mr Joaquim Chissano, independent non-executive director, with effect from 29 November 2022. 1 The increase mainly relates to solar projects of approximately R1 700 million as well as additional capital for the ramping up of the Zaaiplaats and Kareerand projects, and an increase in the translation of the Hidden Valley Mine capital due to the weakening of the Rand to the US$. The solar projects will be financed through the green loan (refer to note 13), with the rest of the expenditure being financed from existing resources and where appropriate, borrowings. Contingent liabilities Randfontein Estates Limited (REL), a subsidiary of Harmony has an existing legal dispute with the Merafong Municipality (Merafong) relating to rates payable in terms of Merafong's Supplementary Valuation Roll 6 (SVR6). REL lodged appeals against the market values contained in SVR6. Merafong is contending for total rates payable of between R194 million and R257 million under SVR6, while Harmony is contending for total rates payable of R17 million on the basis that certain items of the mining operations are not rateable and/or disregarded for valuation purposes and that depreciation, rehabilitation, phasing-in and category use changes are favourably considered by the Merafong Valuation Appeal Board (Merafong VAB). Payment arrangements have been concluded between REL and Merafong in relation to these rates disputes. The Merafong VAB hearings are currently underway with other mining companies with similar legal disputes. Harmony's appeal hearings are set to conclude by the end of the 2024 financial year, where the outcome of the matter will be decided upon by the Merafong VAB. Apart from the above matter, there were no significant changes to Harmony's contingent liabilities. Refer to Harmony's annual financial statements for the financial year ended 30 June 2022.
