Harmony Gold Mining Company Limited Incorporated in the Republic of South Africa Registration number: 1950/038232/06 JSE share code: HAR NYSE share code: HMY ISIN: ZAE000015228 (“Harmony” or “the Company”) Johannesburg, South Africa. Tuesday, 30 April 2024. Harmony Gold Mining Company Limited (Harmony or the Company) is pleased to report its operational update for the nine months ended 31 March 2024 (9MFY24). For this reporting period, Harmony continued delivering an excellent operating performance across its operations, underpinned by higher recovered grades at Mponeng, Moab Khotsong, Hidden Valley and Mine Waste Solutions. The higher recovered grades ensured improved production and lower all-in sustaining costs (AISC) compared to the previous nine-month period ended 31 March 2023 (9MFY23). The higher rand gold price continues to provide Harmony with significant tailwinds, boosting margins and free cash flow generation. Harmony continues to demonstrate operational consistency as a result of its structural advantage and position as a leader in South African gold mining. While the third quarter is traditionally slower due to the January start up and public holidays in March, this is in the plans and we remain on track to comfortably beat our original production, cost and grade guidance for the financial year 2024 (FY24). On the back of this and the strong year-to-date performance, guidance for FY24 has been revised as follows: • Total production guidance increased to approximately 1 550 000 ounces from 1 380 000 to 1 480 000 ounces • All-in sustaining cost guidance reduced to approximately R920 000/kg, from below R975 000/kg • Grade guidance increased to approximately 6g/t, from 5.6 to 5.75g/t • Capital guidance for FY24 is adjusted lower to R8 600 million (US$459 million) from R9 500 million (US$507 million), mainly as a result of lower plant and services capital. A full comparison of quarter-on-quarter and year-on-year production metrics is provided in the summary table below and in the operating tables which are available in the booklet and on the website at www.harmony.co.za. Average recovered grades at the South African underground operations increased by 8% to 6.16g/t from 5.68g/t in the previous reporting period. Our high-grade underground operations, Mponeng and Moab Khotsong, continue to be the primary drivers behind the improvement in underground recovered grades year to date. Underground recovered grades at these mines increased by 18% to 8.90g/t from 7.53g/t year-on-year and we expect the good grades at Mponeng to be sustained as we mine through the high-grade areas on the 123 and 126 levels. We are encouraged that development grades at Mponeng also continue to trend higher. At our South African optimised underground portfolio, recovered grades increased by 2% to 4.96g/t from 4.87g/t, driven by improved performances at Tshepong North, Tshepong South, Kusasalethu and Target 1. Recovered grades at Hidden Valley remained high into the third quarter of the 2024 financial year, increasing by 65% to 1.65g/t from 1.00g/t in the previous nine-month reporting period as we mined through the high-grade 'Big Red' part of the ore body. Going forward, recovered grades at Hidden Valley will be lower as we are now mining through lower-grade areas, as planned. At our South African surface operations, recovered grades increased by 29% to 0.22g/t from 0.17g/t. This was mainly due to a 41% increase in recovered grades at Mine Waste Solutions to 0.168g/t from 0.119g/t. Group gold production in 9MFY24 increased by 10% to 36 777kg (1 182 405oz) from 33 349kg (1 072 195oz) in the previous reporting period. Most of our operations continue to deliver an improved operating performance year-on-year and we have good momentum and flexibility heading into the final quarter of FY24. The rand gold price remains high and increased by 17% to R1 162 048/kg (US$1 928/oz) from R992 566/kg (US$1 768/oz) year-on-year. This has allowed us to further strengthen the balance sheet which remains robust as a result of the strong free cash flow generation. Net cash increased to R1 544 million (US$82 million) from R74 million (US$4 million) at the end of the first six months of this financial year (H1FY24). We currently have R11 591 million (US$612 million1) in headroom available through cash and undrawn facilities. 1 Converted at an exchange rate of R/US$18.94 Gold revenue increased by 26% to R42 397 million (US$2 262 million) in 9MFY24 from R33 539 million (US$1 921 million) for 9MFY23. KEY HIGHLIGHTS (9MFY24 vs 9MFY23) • Group LTIFR# at 5.60 from 5.50; long-term safety performance trending in the right direction but more needs to be done • We have revised our FY24 production and grade guidance upwards and reduced our cost and capital guidance • 8% increase in average underground recovered grades to 6.16g/t from 5.68g/t • 10% increase in total gold production to 36 777kg (1 182 405oz) from 33 349kg (1 072 195oz) • 2% decrease in group all-in sustaining costs (AISC) to R877 965/kg (US$1 457/oz) from R893 985/kg (US$1 592/oz) • Conclusion of landmark five-year wage agreement on 4 April 2024 ensures stability and predictability of our labour costs • 17% increase in average rand gold price received to R1 162 048/kg (US$1 928/oz) from R992 566/kg (US$1 768/oz) • 26% increase in gold revenue to R42 397 million (US$2 262 million) from R33 539 million (US$1 921 million) • 171% increase in group operating free cash flow to R8 774 million (US$468 million) from R3 237 million (US$186 million) driven by higher recovered grades at Mponeng, Moab Khotsong, Hidden Valley and Mine Waste Solutions • Robust balance sheet with net cash increasing to R1 544 million (US$82 million) from R74 million (US$4 million) in H1FY24 • Rolling gold hedge book expanded in anticipation of higher capital expenditure programme • Execution of key projects namely Moab Khotsong extension and Mine Waste Solution on track, preparatory work started at Mponeng and early works to begin at Eva Copper Project # LTIFR – lost-time injury frequency rate per million hours worked Unless otherwise indicated, all currency conversions for this reporting period are at the average exchange rate of R/US$18.75 (9MFY23: R/US$17.46) Please note that financial information has not been reviewed or audited by the Company's external auditors OPERATIONAL UPDATE for the nine months ended 31 March 2024 (9MFY24) OPERATIONAL EXCELLENCE AND HIGH RECOVERED GRADES ENSURE STRONG PRODUCTION AND FREE CASH FLOW GENERATION. ANNUAL GUIDANCE ADJUSTED ON THE BACK OF OUTSTANDING PERFORMANCE
2 Harmony Gold Mining Company Limited | Operational Update for the nine months ended 31 March 2024 Silver production from Hidden Valley increased by 61% to 85 371kg (2 744 728oz) from 53 003kg (1 704 070oz) in 9MFY23. The average silver price received also increased by 21% to R14 147/kg (US$23.47/oz) from R11 723/kg (US$19.45/oz) in 9MFY23. As a result, we generated R1 197 million (US$64 million) in silver revenue at Hidden Valley for this reporting period. Uranium is a by-product from the gold extraction process at Moab Khotsong. Uranium production increased by 28% to 203 334kg (448 274lb) in 9MFY24 from 159 122kg (350 804lb) in 9MFY23. Uranium sold increased by 21% to 160 118kg (353 000lb) from 132 449kg (292 000lb). The average uranium price received has increased by 43% to US$65.74/lb from US$45.97/lb in 9MFY23, resulting in uranium revenue of R435 million (US$23 million) for the nine-month period. Uranium sales of 73 049kg (161 000lb) was not realised within the quarter due to export challenges. This will be realised during the fourth quarter. Cost control remains of critical importance, especially as gold prices continue rising to record levels. While our cost metrics per unit have remained steady in rand terms, we have seen a meaningful improvement in US dollar terms as a result of the weaker rand. Over 90% of our input costs are in rand, with electricity and labour comprising roughly 70% of our operating costs. Further cost improvement has been on the back of sustained higher by-product credits from silver and uranium. • Cash operating costs increased by only 1% to R747 669/kg (US$1 241/oz) from R742 145/kg (US$1 322/oz) • All-in sustaining costs decreased by 2% to R877 965/kg (US$1 457/oz) from R893 985/kg (US$1 592/oz) • All-in costs (AIC) were flat in rand at R942 150/kg (US$1 563/oz) from R939 547/kg (US$1 674/oz) Group operating free cash flows increased by 171% in the 9MFY24 to R8 774 million (US$468 million) from R3 237 million (US$186 million) in 9MFY23. Group operating free cash flow margins increased to 21% in this reporting period from 10% in the previous nine-month reporting period, driven mainly by operating free cash flows at our South African high-grade underground mines, Hidden Valley and South African surface operations. Operating free cash flow margins from our South African optimised portfolio, or legacy assets, improved to 8% from 5%. Harmony has significantly improved the quality of its portfolio and will continue allocating capital in a manner that drives further margin expansion and higher returns. We have a comprehensive project pipeline and remain on track with our key projects that are in execution. These include the tailings storage facility expansion at Mine Waste Solutions, which is on track for completion in FY25, and the life of mine extension project at Moab Khotsong. At Mponeng, we have commenced preparatory work to ensure the timeous start of the life of mine extension project in July 2024. This project extends the life of mine at Mponeng to 20 years, adding approximately 2.3Moz to Mineral Reserves. Major capital for the extension of Mponeng is planned at R7.9 billion over the life of the project. As previously guided, this project will result in an approximately R1 billion (US$53 million) in additional capital expenditure both in FY25 and FY26. The Company does not provide capital guidance beyond two years. Our projects are well-sequenced to ensure capital expenditure remains affordable, with all existing project capital internally funded. Our robust balance sheet and effective hedge programme provide further support should there be an adverse movement in the gold price. Safety, effective cost management and delivering operational excellence across all our operations go hand-in hand. A proactive safety culture and operational excellence have resulted in the continued improvement in our safety performance. HEALTH AND SAFETY Long-term safety indicators continue to trend in the right direction and we remain encouraged by the remarkable improvement in safety over the past few years. We continue working tirelessly to improve safety as we embed a proactive safety culture throughout Harmony. There has been a slight regression in the group LTIFR for 9MFY24 to 5.60 per million hours worked, from 5.50 in 9MFY23. This was a result of an increase in the less severe agencies such as slip-and-fall. Accidents from traditional high-energy agencies such as fall-of-ground and rail-bound equipment continue trending lower. We extend our heartfelt condolences to the family of Mr Santos Ernesto Uenzane, Mine Overseer at Mponeng, who tragically lost his life from a heat-related incident on 4 January 2024 during the pre-start up inspection after the December 2023 break. Each life lost reminds us that we can never be complacent and more needs to done as we continue our relentless pursuit of achieving zero loss of life. We continue to deliver pro-active and holistic healthcare to all our employees ensuring their health and well-being. STABLE LABOUR RELATIONS: FIVE-YEAR WAGE AGREEMENT CONCLUDED On 4 April 2024, Harmony concluded a landmark five-year wage agreement in respect of increases to wages and other conditions of service at its South African operations with its five labour unions, being the Coalition (comprising the NUM, UASA and Solidarity), AMCU and NUMSA. The agreement is for the period 1 July 2024 to 30 June 2029, and will take effect on 1 July 2024. This is testimony to the strength of our labour relations and ensures stability and continued certainty on our fixed labour costs for the next five years. The wage negotiations were carried out in good faith and Harmony commends all parties for demonstrating good leadership by engaging constructively. This agreement will result in an increase in South African operations labour costs of approximately 6% per annum over the five-year period which is within Harmony's planning parameters. As part of our endeavours to create long-term value for all our stakeholders, including our employees and host communities, on 11 December 2023, the Company proposed two broad-based black economic empowerment (B-BBEE) transactions involving: • the specific issue of no par value convertible preference shares by Harmony to the trustees for the time being, of the Harmony Gold Community Trust; and • the specific issue of no par value ordinary shares by Harmony to the trustees for the time being, of the Harmony Employee Share Ownership Plan Trust for the benefit of Eligible Employees. These transactions create shared value and strengthen partnerships as we grow our business and develop thriving communities where we operate. EVA COPPER PROJECT: INTERIM UPDATE ON FEASIBILITY STUDY AIMED AT DE-RISKING THE PROJECT The Eva Copper Project (the Project), located in the tier 1 mining jurisdiction of north-west Queensland, Australia, was acquired by Harmony in December 2022. It brings the potential for near-term, low-cost copper production into the Harmony production profile, providing the Company with counter-cyclical diversification in what has historically been a pure gold portfolio. Since acquisition, Harmony has been conducting a robust, risk-based and rigorous feasibility study assessment of Eva Copper. Our focus has been on increasing confidence in the resource and completing further technical and economic trade-off analysis to identify, inform and confirm the preferred option for project development. These studies underpin achieving a high-quality, and sustainable mining operation. An extensive resource drilling programme was initiated in March 2023 and is ongoing, with over 70 000 metres drilled to date. The drilling has: a. added to the Project’s resource base and increased confidence in, and understanding of the project area’s geology, geohydrology, metallurgy and geotechnical composition b. demonstrated good prospectivity including potential for life of mine extension Drilling continues in parallel with Project definition to expand the existing resource base and to convert other deposits in Harmony’s tenement area. Harmony has significantly increased the copper and gold Mineral Resource since acquisition. Our current declared Mineral Resource for Eva Copper sits at 354Mt @ 0.42% Cu for 1 492Kt of copper and 184Mt @ 0.07g/t Au for 431Koz of gold. This is a significant increase over the previous owners Resource of 307Mt @ 0.42% Cu for 1 289Kt of copper and 148Mt @ 0.08g/t Au for 379Koz of gold. Please refer to our Mineral Resources and Mineral Reserves statement as at 30 June 2023 (FY23). Life-of-mine all-in-sustaining cost is anticipated to be in the second quartile of the industry cost curve, ensuring Harmony as a group continues to reduce its overall costs. Detailed technical and commercial work to inform the preferred power solution for the Project continues. To help Harmony achieve its ambition of being net carbon zero by 2045, renewables have been included in the proposed energy mix in anticipation of future grid connection as part of the Queensland Government’s CopperString project. CopperString is the largest ever economic development project in North Queensland and aims to connect the State’s north-west minerals province to the national electricity grid by 2029. Determining a sustainable primary water supply for the Project has required an extensive programme of drilling, pump test work, and modelling that is due
3 Harmony Gold Mining Company Limited | Operational Update for the nine months ended 31 March 2024 for completion by the end of the 2024 calendar year. The Study has indicated a potential water source on the Mining Lease that may support a proposed increased processing rate and production profile at Eva Copper. Eva Copper will be a conventional open-cut mine comprising multiple pits with a low strip ratio, mined in a select sequence, feeding a copper concentrator based on a proven processing flow sheet and technology selection. The ore bodies at Eva Copper are wide and predictable while a modern plant design and conventional technology will ensure low production ramp-up risk. Based on the extensive work done to date, it is anticipated that the processing facility will have greater capacity than indicated by the Project's previous owner. Along with the effect of scope change and inflationary impacts since acquisition, the Project will require a higher capital investment than what was anticipated in the previous owner’s feasibility study. Capital cost estimates and funding models for the Project will be prepared as part of the Feasibility Study which will be used to inform a reserve declaration. The Project provides an excellent platform for growth, encompassing a tenement package in excess of 2 400 square kilometres in a highly prospective, world-class mining jurisdiction with supporting infrastructure. Pending a positive feasibility study outcome, permitting and board approval, Harmony is confident it will be in a strong position to fund the construction of this mine in a manner that continues to create long-term value and is in the best interest of all shareholders and stakeholders. Development is likely to be funded through a combination of strong operating free cash flows, corporate debt, leveraging our strong balance sheet and supported by our effective hedge strategy. Permitting Sustainability is embedded in our operating model, and Harmony has proven itself as the partner of choice wherever we operate. The Project has a current Environmental Authority in place in support of development. However, based on work done to date and noted above, the Environmental Authority will require permit amendments in terms of the proposed power and water solution and project configuration based on the anticipated feasibility study outcomes. The Queensland Government’s recent declaration of Eva Copper as a ‘Prescribed Project’, designating the Project as one of economic and social significance to the State, will streamline the permit amendment process and assist in expediting outcomes specifically as it relates to amendments to the current Environmental Authority in place for the Project, which are required to accommodate the optimised design outlined above. It is anticipated that this process could take up to 18 months. A Final Investment Decision on the project will therefore only be considered once all approvals have been obtained – likely towards the end of the calendar year 2025. In addition to ongoing feasibility study work, some initial site preparatory works have been commissioned and will continue in the coming months to improve and de-risk access to the site, support and de-risk current drilling efforts on site, and prepare the site for the construction phase. The proposed works include site access roads, temporary accommodation facilities and associated services and infrastructure, fencing and lay down areas. Capital for this is expected to be not material and will be easily funded through existing cash flows. HEDGING UPDATE During the quarter, the gold hedge book was maintained at 20% of two years' expected gold production. The average forward rand gold price on the hedge book is at R1 299 000/kg on a net position of 570 000oz at the end of the third quarter. Harmony will only hedge when it is certain that it can achieve a minimum margin of 25% above AISC and inflation. The previous policy was to hedge up to 20% of our production over a rolling two-year period. However, due to the pipeline of projects and anticipated higher capital expenditure, we have received board approval to increase the size and the term of the hedge book. The rolling gold hedge book programme has been increased as follows: • Year 1: percentage hedge cover increased by 10% to 30% of production • Year 2: hedge cover unchanged at 20% • Year 3: percentage hedge cover of 10% from zero We remain fully exposed to spot gold prices for the unhedged production. CONCLUSION The excellent operating results in this reporting period have been a function of our ongoing investment in safety, quality ounces and operational excellence. This ensures consistent delivery throughout the gold cycle. Harmony remains well-positioned to take advantage of the current high gold prices and we are prudent with our allocation of capital to ensure long-term value creation. Our costs remain under control, and being a predominantly South African gold miner is proving advantageous due to our stable and predictable rand cost structure. The improvement in safety and operational flexibility alongside effective capital allocation assures the consistent delivery of the tonnes alongside higher-quality ounces, thereby generating positive free cash flows. With our substantial Mineral Resource base of almost 140 million ounces, Harmony offers an abundance of opportunity to grow our Mineral Reserves while diversifying into copper. We continue to invest in our ore bodies, converting resources into quality reserves and production through our organic project pipeline. Value accretive acquisitions form part of our strategy and we continue to look at growth opportunities in Africa, South East Asia and Australia. Holistic sustainability requires fundamental changes at all levels of social, economic, political and cultural structures. Sustainable mining ensures we always meet the needs and aspirations of both present and future generations in a clear socio-economic, historic and environmental context by delivering on our four strategic pillars namely, Responsible Stewardship, Operational Excellence, Cash Certainty and Effective Capital Allocation. By embedding sustainability in our operating model, Harmony contributes positively towards the eradication of poverty, social injustice and inequalities wherever we operate.

9 Harmony Gold Mining Company Limited | Operational Update for the nine months ended 31 March 2024 FORWARD-LOOKING STATEMENTS This booklet contains forward-looking statements within the meaning of the safe harbour provided by Section 21E of the Exchange Act and Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), with respect to our financial condition, results of operations, business strategies, operating efficiencies, competitive positions, growth opportunities for existing services, plans and objectives of management, markets for stock and other matters. These forward-looking statements, including, among others, those relating to our future business prospects, revenues, and the potential benefit of acquisitions (including statements regarding growth and cost savings) wherever they may occur in this booklet, are necessarily estimates reflecting the best judgment of our senior management and involve a number of risks and uncertainties that could cause actual results to differ materially from those suggested by the forward-looking statements. As a consequence, these forward-looking statements should be considered in light of various important factors, including those set forth in our integrated annual report. By their nature, forward-looking statements involve risk and uncertainty because they relate to future events and circumstances and should be considered in light of various important factors, including those set forth in this disclaimer.
