OPERATIONAL UPDATE for the nine months ended 31 March 2026 ("9MFY26") STRONG THIRD QUARTER. RETURN TO NET CASH POSITION. ON TRACK TO ACHIEVE GUIDANCE. Johannesburg, South Africa. Monday, 18 May 2026. Harmony Gold Mining Company Limited ("Harmony" or "the Company") is pleased to report its operational update for the nine months ended 31 March 2026. 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") › Harmony Gold Mining Company Limited | Operational Update for the nine months ended 31 March 2026 1 MESSAGE FROM THE CHIEF EXECUTIVE OFFICER Overview Harmony delivered a solid operating performance for the nine months to 31 March 2026, reflecting an excellent third quarter with improvements across all key operational metrics. Mponeng, Hidden Valley and Tshepong North delivered notable performances during this quarter. We remain firmly on track to achieve full‑year production, cost and grade guidance for both gold and copper, supporting durable returns. This will mark our 11th consecutive year of meeting production guidance, underpinned by operational excellence, higher‑quality assets, strong grade control and resilient margins. Gold and copper revenue increased by 34% to R68 385 million (US$4 016 million), driven by a 39% increase in the average gold price received to R2 020 821/kg (US$3 691/oz). Leveraged exposure to the gold price helped drive a year-on-year increase of 87% in free cash flow at an operational level. Cost inflation remains well controlled and in line with plan, while production is supported through ongoing quality Mineral Reserve replacement. Strong cash generation, bolstered by our high-margin gold operations, enabled the Group to return to a net cash position of R1 326 million (US$78 million), from a net debt position of R5 554 million (US$335 million) at 31 December 2025. Balance sheet strength remains central to our strategy, providing the flexibility to fund growth, protect margins and deliver sustainable shareholder returns. We continue to assess our capital structure to maintain an efficient balance sheet that is appropriately matched to both our funding needs and the strength of our cash‑flow generation. We allocate capital in a disciplined and balanced manner, prioritising safety and orebody development while delivering quality growth in both gold and copper. Execution excellence on our key growth projects over the next 24 months is critical as we establish a clear pathway to higher‑margin gold production and approximately 100 000 tonnes of copper per annum. This investment programme is well sequenced to manage capital intensity and maintain a robust and flexible balance sheet. Margin protection and enhancement remain core priorities, supported by ongoing investment in a mix of higher‑grade orebodies and other high‑margin projects that deliver strong returns on capital, helping to sustain resilient cash flows through the cycle. As anticipated, the high-grade Moab Khotsong mine is entering a five-year period of planned lower production as we advance the Zaaiplaats extension project. The CSA copper mine was a strategic acquisition to mitigate this, and its integration and optimisation is progressing in line with plan. Mining flexibility at CSA remains constrained but is improving following the re-establishment of an appropriate mining sequence, while the ventilation project is on schedule to support long-term performance. Ongoing drilling continues to deliver exceptional results, reinforcing the quality and potential of this high-grade copper orebody. Shareholder returns are expected to remain sustainable and competitive alongside our growth strategy. Under our new dividend policy, the base dividend was increased to 30% of net free cash*. In addition, an upside dividend of up to 20% may be paid, based on net debt to EBITDA (leverage) levels. Therefore, a total of 50% of net free cash can be returned to shareholders, subject to the discretion of the board and leverage. A record interim dividend of R3 375 million (US$204 million) or 530 SA cents (32 US cents) per share was paid on 28 April 2026. * Net free cash is defined as operating free cash flow after capital, interest, tax, corporate and other expenses.

Safety is our first value and we are deeply saddened by the loss of two colleagues, Lephethesang Khetheng at Moab Khotsong and Olga Ramolehe at Target 1, in the third quarter. We extend our sincere condolences to their families, friends and colleagues. Their loss weighs heavily on us and reinforces our unwavering belief that nothing is more important than ensuring that every person returns home safely. We remain resolute in our commitment to learn from every incident and to continually strengthen the decisions, behaviours and systems that protect the lives of our people. We are making steady progress in our safety performance, with improvements in key risk areas and the achievement of several significant, loss‑of‑life‑free milestones during the quarter. We are encouraged that Group LTIFR remains below 5.00 at 4.71 per million hours worked. However, every work-related incident underscores that more work must be done to further embed a consistently safe and vigilant culture across all operations. Our safety strategy is evolving to strengthen preventive controls, enhance risk management and target interventions at high‑risk activities. This is supported by ongoing improvements in engineering solutions, technology‑enabled systems and behavioural change through our Thibakotsi culture journey. We recognise that a sustainable safety performance is ultimately driven by our people. Our Accountability Model reinforces clear standards and expectations, while supporting a culture of learning, ownership and continuous improvement. Alongside this, we are a more resilient and responsible business. Sustainability remains embedded in how we plan, operate and invest, as reflected in the recent upgrade of Harmony’s MSCI ESG rating from ‘BB’ to ‘A’. Our renewable energy programme, now one of the largest of its kind in South Africa, also advanced meaningfully during the quarter, with Sungazer 2 nearing completion. These initiatives support both our decarbonisation ambitions and long-term cost and energy resilience. We are recycling approximately 78% of our water, and continued investment in our communities reflect Harmony’s commitment to shaping a more resilient and inclusive future through embedded and sustainability-led value creation. Consistent delivery Our de‑risked portfolio of underground, surface and tailings retreatment operations supports consistent delivery, and we are pleased with the overall performance of our operations year to date. Importantly, the cyanide and recovery issues experienced at our South African operations in the prior quarter have been resolved. A solid performance in the third quarter saw total gold production increase by 5% to 10 871kg (349 511oz) from 10 394kg (334 176oz) in the second quarter of the financial year 2026 (Q2FY26). Although Group gold production declined by 3% to 33 393kg (1 073 610oz) for the nine-month period, this was in line with plan. While underground recovered grades for our gold operations declined by 7% to 5.85g/t for the nine‑month period, performance rebounded strongly in the third quarter, with recovered grades increasing to 6.15g/t from 5.52g/t in the second quarter. Copper production from the CSA mine has totalled 9 596t (21.2Mlb) since acquisition on 24 October 2025, including a one‑month production stoppage to complete the shaft steel replacement. Notwithstanding the planned stoppage, we remain on track to meet our copper production guidance for the financial year. Recovered grades for CSA copper mine in this reporting period was 3.49%, in line with plan. Disciplined cost control and margin protection Costs remain under control and we are actively monitoring the impact of higher oil prices and potential supply disruptions across our global operations. Labour and electricity are the largest component of Group costs and at this stage, we do not anticipate any material cost escalation or risk to guidance. As planned, total cash operating costs increased year-on-year by 10% to R32 646 million (US$1 917 million) from R29 811 million (US$1 646 million), in line with planned inflationary increases and higher royalties. Royalties for our South African operations, which make up 7% of cash operating costs, increased by 94% to R2 166 million (US$127 million) from R1 116 million (US$62 million) on the back of improved profitability. Despite the sharp increase in royalties, our AISC remains within guidance. • Per-unit costs increases at our gold operations were all in line with plan: – Cash operating costs increased by 13% to R977 642/kg (US$1 786/oz) from R861 916/kg (US$1 480/oz) – All-in sustaining costs increased by 14% to R1 167 679/kg (US$2 133/oz) from R1 027 912/kg (US$1 765/oz) – All-in costs (AIC) increased by 15% to R1 295 059/kg (US$2 366/oz) from R1 121 938/kg (US$1 927/oz) • Per-unit costs at our CSA copper operations remain competitive: – C1 cash costs of US$2.58/lb, well below the guided range of US$2.65/lb to US$2.80/lb Hedging Ongoing volatility in commodity and currency markets reinforces the importance of disciplined risk management as Harmony advances its growth strategy. The Group’s hedging approach is designed to protect margins and cash flows, providing funding certainty for capital expenditure and project execution while retaining meaningful exposure to favourable price movements. As at 31 March 2026, Harmony had hedged 592 000 ounces (18 413kg) using rand gold zero cost collars at an average floor and cap of R2 037 000/kg and R2 291 000/kg, respectively. These averages have increased by 6% from the previous quarter. This is a result of the positive impact of new collars entered into during the third quarter at an average floor price of R2 719 000/kg and a cap of R3 020 000/kg. ›‹ MESSAGE FROM THE CHIEF EXECUTIVE OFFICER continued Harmony Gold Mining Company Limited | Operational Update for the nine months ended 31 March 2026 3 Gold and copper growth: Unlocking significant embedded value Our brownfield and greenfield projects, including the Mponeng and Moab Khotsong extensions, are advancing in line with plan, with project execution excellence central to long-term value creation. Feasibility studies are underway to expand our surface retreatment operations in the Free State and West Wits, building on the success of Mine Waste Solutions. In addition, we are exploring possible mine-life extension opportunities as part of our annual planning cycle. Eva Copper Construction at the Eva Copper Mine Project is progressing safely, and is tracking on schedule and within the approved capital estimate. This performance reflects Harmony’s focused execution since Final Investment Decision in November 2025. All major construction contracts have now been awarded, and the Project has achieved several key milestones: • The Environmental Authority Major Amendment approval was received on 15 May 2026 • Process plant construction and non-process infrastructure works commenced in April 2026 • Drilling activities have resumed after the wet season. A comprehensive infill drilling programme has been designed to increase Indicated Mineral Resource inventory to support future Mineral Reserve conversion • Aggreko has been appointed as the independent power provider and we are working closely with the Queensland Government on longer-term power supply options, including the CopperString grid connection The Queensland Government’s Prescribed Project declaration for Eva Copper has been officially extended to March 2028, maintaining whole-of-government support and coordination to streamline approvals through the major construction phase. This status has been further strengthened by the establishment of the Cross-Agency Assessment Team by the Queensland Government on 2 April 2026 to accelerate approvals for key resource projects, including the Eva Copper Mine Project. As partner of choice, sustainability and local engagement remain central to the Project’s development. Harmony is currently working with 83 local suppliers across the region. In line with Harmony’s commitment to a "local first" approach, we are proactively engaging with Traditional Owners, the Kalkadoon People and host communities on employment, housing and broader socio-economic development outcomes for the region. Wafi-Golpu We remain committed to advancing this Tier‑1 transformational copper‑gold asset and our engagement with the Government of Papua New Guinea and the Independent Peer Review Team continues. FY26 grade, production and cost guidance With one quarter of production remaining for FY26, we are confident that we will achieve our full-year guidance of: • Gold: – 1 400 000oz to 1 500 000oz in total production – overall AISC guidance of between R1 150 000/kg to R1 220 000/kg – underground recovered grade at above 5.80g/t • Copper: – 17 500 to 18 500 tonnes – C1 cash costs of between US$2.65/lb and US$2.80/lb – recovered grade above 3.50% In conclusion Anchored in Mining with Purpose, underpinned by a resilient gold foundation, industry‑leading operational discipline and rigorous capital allocation and strengthened by a high‑quality, growing international copper portfolio, Harmony is a leading global gold and copper producer, executing a clear, disciplined strategy to deliver sustainable long‑term value through commodity cycles.

Underground recovered grades remained above reserve grade at 10.49g/t, while tonnes milled were stable at 678 000 tonnes, reflecting consistent performance through operational excellence. The Mponeng extension project remains on schedule, with any risk of a production gap effectively mitigated. At Moab Khotsong, recovered grades increased by 54% to 8.80g/t in the third quarter of financial year 2026 (Q3FY26), from 5.73g/t in the second quarter. This reflects lower inventories with the release of gold from the plant and stabilised production at the Great Noligwa pillar following mining sequence adjustments to manage seismicity. For the nine‑month period, recovered grades declined by 15% to 7.18g/t from 8.40g/t, in line with plan. The Zaaiplaats extension project is progressing well, with contractor‑related delays included in the life‑of‑mine plan. International gold and copper Hidden Valley A phenomenal performance was delivered with production increasing by 11% to 4 204kg (135 162oz) and AISC decreasing by 19% to R707 185/kg (US$1 292/oz) in the nine-month period. Gold sold in Q3FY26 increased by 94% to 1 803kg (57 968oz) from the prior quarter, boosted by the deferment of the final gold shipment of Q2FY26 to January 2026. Recovered grades for the reporting period increased by 17% to 1.55g/t from 1.33g/t. Studies are underway to determine the feasibility of a further life-of-mine extension beyond the current mine plan. A potential Stage 9 development is now fully permitted following confirmation of the successful approval of the environmental permit amendment allowing the construction of a third tailings storage facility. The remaining 50% of Hidden Valley was acquired for US$1 in 2016 and the mine was recapitalised over a two-year period. This success underscores Harmony's ability to extract value and extend the lives of our assets through our focus on safety, operational excellence, stringent cost controls and effective capital allocation. It is this same model, which has proven successful at many of our gold assets, that we are now implementing at the CSA copper mine in Australia. CSA copper mine Operationally, our focus remains on improving the flexibility of the mining operations, with full optimisation expected to take up to 24 months. We completed the replacement of the shaft steelwork on six levels as previously indicated. This resulted in a one-month planned shutdown in March 2026. We continue to integrate the mine, ensuring alignment with the disciplined and consistent approach applied to all Harmony assets. Assaying of historical drill samples has now been completed. During the third quarter, follow‑up drilling targeted extensions of mineralisation outside the current Mineral Resource footprint and continued to deliver encouraging results – including 32m @ 8% Cu, 37.4m @ 3.7% Cu and 14m @ 6.5% Cu – building on previously reported intercepts¹. ¹ Refer to H1 FY26 Results Presentation, 11 March 2026 ›‹ ADDITIONAL FINANCIAL AND OPERATIONAL INFORMATION continued Harmony Gold Mining Company Limited | Operational Update for the nine months ended 31 March 2026 6 These high‑grade copper intercepts received during the quarter confirm that mineralisation extends from the main, high‑grade QTS North orebody, demonstrating strong continuity and supporting the overall quality of the ore system. Drilling to further define and extend these newly identified zones is ongoing. Longer‑term production and capital guidance, together with the updated Mineral Resources and Mineral Reserves, will be provided with the release of our full‑year results in August 2026. South African surface source operations Mine Waste Solutions (MWS), Savuka Tailings, Central Plant Reclamation, Phoenix, Kalgold and rock dumps delivered an improved performance following the cyanide shortage which affected production in the previous reporting period. A cyanide dissolution plant has now been commissioned at MWS to mitigate any future cyanide supply risks at these operations. MWS was impacted in the third quarter by high rainfall which affected throughput and electricity supply from Eskom. South African underground optimised operations Our South African optimised portfolio – Tshepong North, Tshepong South, Doornkop, Kusasalethu, Joel, Target 1 and Masimong – remains a significant contributor at 38% of group production for the nine-month period. Production, grade and costs all improved quarter-on-quarter.

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. All statements other than statements of historical facts included in this booklet may be forward-looking statements. 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. Readers are cautioned not to place undue reliance on such statements. Important factors that could cause actual results to differ materially from estimates or projections contained in the forward-looking statements include, without limitation: overall economic and business conditions in South Africa, Papua New Guinea, Australia and elsewhere; the impact from, and measures taken to address, Covid-19 and other contagious diseases, such as HIV and tuberculosis; high and rising inflation, supply chain issues, volatile commodity costs and other inflationary pressures exacerbated by the geopolitical risks; estimates of future earnings, and the sensitivity of earnings to gold and other metals prices; estimates of future gold and other metals production and sales; estimates of future cash costs; estimates of future cash flows, and the sensitivity of cash flows to gold and other metals prices; estimates of provision for silicosis settlement; increasing regulation of environmental and sustainability matters such as greenhouse gas emission and climate change, and the impact of climate change on our operations; estimates of future tax liabilities under the Carbon Tax Act (South Africa); statements regarding future debt repayments; estimates of future capital expenditures; the success of our business strategy, exploration and development activities and other initiatives; future financial position, plans, strategies, objectives, capital expenditures, projected costs and anticipated cost savings and financing plans; estimates of reserves statements regarding future exploration results and the replacement of reserves; the ability to achieve anticipated efficiencies and other cost savings in connection with, and the ability to successfully integrate, past and future acquisitions, as well as at existing operations; our ability to complete ongoing and future acquisitions; fluctuations in the market price of gold and other metals; the occurrence of hazards associated with underground and surface gold mining; the occurrence of labour disruptions related to industrial action or health and safety incidents; power cost increases as well as power stoppages, fluctuations and usage constraints; ageing infrastructure, unplanned breakdowns and stoppages that may delay production, increase costs and industrial accidents; supply chain shortages and increases in the prices of production imports and the availability, terms and deployment of capital; our ability to hire and retain senior management, sufficiently technically-skilled employees, as well as our ability to achieve sufficient representation of historically disadvantaged persons in management positions or sufficient gender diversity in management positions or at Board level; our ability to comply with requirements that we operate in a sustainable manner and provide benefits to affected communities; potential liabilities related to occupational health diseases; changes in government regulation and the political environment, particularly tax and royalties, mining rights, health, safety, environmental regulation and business ownership including any interpretation thereof; court decisions affecting the mining industry, including, without limitation, regarding the interpretation of mining rights; our ability to protect our information technology and communication systems and the personal data we retain; risks related to the failure of internal controls; the outcome of pending or future litigation or regulatory proceedings; fluctuations in exchange rates and currency devaluations and other macroeconomic monetary policies, as well as the impact of South African exchange control regulations; the adequacy of the Group’s insurance coverage; any further downgrade of South Africa’s credit rating and socio-economic or political instability in South Africa, Papua New Guinea, Australia and other countries in which we operate; changes in technical and economic assumptions underlying our mineral reserves estimates; geotechnical challenges due to the ageing of certain mines and a trend toward mining deeper pits and more complex, often deeper underground, deposits; and actual or alleged breach or breaches in governance processes, fraud, bribery or corruption at our operations that leads to censure, penalties or negative reputational impacts. The foregoing factors and others described under “Risk Factors” in our Integrated Annual Report (www.har.co.za) and our Annual Report on Form 20-F should not be construed as exhaustive. We undertake no obligation to update publicly or release any revisions to these forward-looking statements to reflect events or circumstances after the date of this booklet or to reflect the occurrence of unanticipated events, except as required by law. All subsequent written or oral forward-looking statements attributable to Harmony or any person acting on its behalf are qualified by the cautionary statements herein. Any forward-looking statements contained in these financial results have not been reviewed or reported on by Harmony's external auditors. Competent Person’s statement The Mineral Resource and Mineral Reserve figures published in this booklet are updated as at 30 June 2025. Harmony confirms that it is not aware of any new information or data that materially affects the information included in the statement, in the case of Mineral Resources or Mineral Reserves, that all material assumptions and technical parameters underpinning the estimates in the original release continue to apply and have not materially changed. Harmony confirms that the form and context in which the competent person’s findings are presented have not been materially modified from the original release. Exploration results relating to recent drilling at the CSA copper mine are presented in summary form and should not be construed as Mineral Resources or Mineral Reserves, nor relied upon as an estimate of economic mineralisation. ›‹
