Harmony Gold Mining Company (JSE:HAR) News - Operational update for the three months ended 30 September 2021 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") OPERATIONAL UPDATE for the three months ended 30 September 2021 ("Q1FY22") DE-RISKED PORTFOLIO DRIVES QUARTER-ON- QUARTER PRODUCTION GROWTH Johannesburg, South Africa. Thursday, 11 November 2021. Harmony Gold Mining Company Limited ("Harmony" or "the Company") is pleased to report our operational performance for the three months ended 30 September 2021 ("Q1FY22"). OVERVIEW The operational results for the first quarter of the financial year 2022 were underpinned by a diversified and de-risked portfolio. Newly acquired assets and assets that we have reinvested in, now represent 62% of operating free cash flow, while our surface source operations accounted for 34% of operating free cash flow this quarter. Assets which have been in Harmony's portfolio for many years accounted for only 4% of the operating free cash flow this quarter, which illustrates how we have transformed our portfolio through the acquisition of quality ounces. Harmony's re-engineered portfolio has shown a 27% increase in underground tonnes milled for the September 2021 quarter when compared to the September 2020 quarter and a 26% increase in gold production from our underground mines. Total gold production was 32% higher this quarter when compared to Q1FY21. Some of the key highlights in Q1FY22 include a 3% increase in production by the surface source operations and a 4% increase in tonnes milled by the underground operations. The quarter-on-quarter increase in underground production was on the back of improved grades and tonnes milled at our Moab Khotsong, Kusasalethu, Target 1 and Doornkop operations. Overall production was more or less steady quarter-on- quarter with 12 868kg (413 714oz) of gold produced in Q1FY22 compared to 12 786kg (411 078oz) produced in Q4FY21. Encouragingly, total production excluding Mponeng and related assets and Unisel mine (which was closed in October 2020) - delivered an additional 6% of gold production compared with the September 2020 quarter as a result of higher tonnes milled as production normalised post the Covid-19 disruptions and improved efficiencies on the back of various optimisation projects. Harmony's balance sheet remains strong, with net debt to EBITDA now at 0.05 times at the end of the quarter (0.1 times in the previous quarter) as we further reduced our net debt by R139 million (US$9 million) to R454 million (US$30 million). The Company's strategy remains unchanged - delivering on safe profitable ounces and increasing margins, while focusing on our four strategic pillars namely: responsible stewardship, operational excellence, cash certainty and effective capital allocation. A quality portfolio, deleveraged balance sheet, commitment to best environment, social and governance (ESG) practices and an exciting pipeline of projects will ensure Harmony continues to create value for all shareholders and stakeholders.

For the reporting period, the non-recurring events include the gain on bargain purchase and acquisition-related costs. Adjusted EBITDA may not be comparable to similarly titled measures of other companies. Adjusted EBITDA is not a measure of performance under IFRS and should be considered in addition to and not as a substitute for other measures of financial performance and liquidity RESPONSIBLE STEWARDSHIP The Company continues to place a strong focus on our ESG initiatives as a good corporate citizen. We believe in full transparency and adherence to global best practice. As part of our commitment to open and transparent disclosure, the ESG report and Taskforce for Climate-related Financial Disclosure (TCFD) report are now available as part of the suite of reports for FY21 which were published on 28 October 2021. These reports can be accessed at http://www.harmony.co.za. Every effort is made to ensure the safety of the close to 60% (almost 30 000 people) of our workforce actively involved in mining operations every day. We believe that zero loss of life is possible. Our Humanistic Transformation Programme, or Thibakotsi journey, is aimed at all employees and contractors and will create a pro-active safety culture and an environment where employees at all levels live the company values and experience high levels of engagement, mutual trust, respect, and hope. Through continual reinforcement, we believe we can embed a changed behaviour with a positive attitude towards safe living and working. Through this change in behaviour we will see a significant reduction in accidents and ultimate elimination of loss of life. Although we are making progress in creating safer working areas, loss-of-life incidents still do occur for numerous reasons. Each incident is meticulously investigated, scrutinised and learnt from to ensure we eliminate and reduce the chance of re-occurrence. Tragically, three employees lost their lives during the quarter: 1. On 15 July 2021 at Tshepong Operations, Mr Thembile Simon Mabala was caught by a scraper winch rope during sweeping operations. 2. On 6 August 2021 at Moab Khotsong, Mr Pule Jan Mokhatsi was busy with cleaning operations in a stope panel when a gravity-related fall of ground occurred. 3. On 1 September 2021 at Mponeng, Mr Richard Mohapi was busy with drilling operations in a stope panel when a seismic-related fall of ground occurred. The management of Harmony sends their heartfelt condolences to families, friends and colleagues of those who lost their lives with assurances to all our stakeholders that we are doing all we can to eliminate these tragedies. It takes time to carefully assess and plan which underground areas are in fact safe enough to mine and change embedded behaviour. We exclude unsafe areas from our operational plans - even if it means that we sacrifice production ounces. All our employees are encouraged to notify their line managers of areas they deem unsafe and every person has the right to not enter an area if they do not feel completely safe to do so. Harmony distributes digital reports on a daily basis to all of our mining staff highlighting any potential risks which helps awareness whilst encouraging a mindset prioritising safety above all else. During the past quarter, our lost time injury frequency rate (LTIFR) improved from 6.10 to 6.04 per million hours worked compared to the last quarter. The fall of ground injury frequency rate (FOGIFR) improved from 1.53 to 1.48 per million hours worked. Seismicity, fatigue and poor discipline were among the reasons for a regression in the reportable injury frequency rate (RIFR) from 3.49 to 4.24 and the fatal injury frequency rate (FIFR) regressing from 0.00 to 0.12 per million hours worked. We had some notable achievements during the quarter and it is important to give credit to all Harmony employees who helped achieve these important milestones as we strive for a safe working environment: - At the end of Q4FY21, Harmony's South African operations recorded 107 fatal-free days - which represents 3 259 048 fatal-free shifts. Furthermore, on 14 July 2021, we recorded 121 fatal-free days and 3 682 069 fatal-free shifts. This is the highest number of fatal-free shifts achieved in Harmony's history - Our South African underground operations achieved 3 million fatal-free shifts, of which Tshepong and Doornkop achieved 1 million fatal-free shifts each - Mponeng and Saaiplaas Plants achieved 39 000 and 22 000 fatal-free production shifts respectively Please see the Company's FY21 integrated annual report and website for more information on our safety initiatives and the incidents reported during the quarter: http://www.harmony.co.za. HEALTH Harmony's vaccination drive - in collaboration with the South African Government and the Minerals Council of South Africa - aimed at vaccinating at least 80% of our employees before the end of November 2021, has progressed exceptionally well. Following various education and engagement initiatives, close to 80% of our employees have received their first vaccination while close to 61% of our workforce is fully vaccinated. Throughout the Company, we continue with our initiatives to reduce the spread of Covid-19 infections through the implementation of precautionary measures, education, awareness and improved hygiene and infection control practices. Strict adherence to our existing Covid-19 protocols remain in place at all our operations. OUR PEOPLE At Harmony, we understand that our people are central to our success. Testimony to this, was the conclusion of a historic three-year wage agreement which saw all five unions signing the wage deal on the same day. As South Africa's largest gold miner by volume, Harmony has an on-going and important role to play in creating value for all our stakeholders. Effective capital allocation extends not only to projects and operations, but also to the people who work at Harmony. This in turn creates infinite opportunities through the mining of a finite resource, thereby ensuring the lives of the people and the many host communities who benefit from the Harmony operations are improved each and every day.

ENVIRONMENT Looking to the future, Harmony's strategy includes a decarbonisation plan aimed at a greener and more equitable future for all. We are in the process of finalising our short-term emissions targets and our net-zero strategy. We are rolling out the first phase of our renewable energy programme, by erecting a 30MW solar energy plant in the Free State province. The Tier 1 Wafi-Golpu project remains a key deliverable as Harmony entrenches itself as an emerging market copper-gold mining specialist with exposure to green metals.

PRODUCTION A 4% higher gold price received of R832 756/kg (US$1 771/oz)in Q1FY22 compared to R803 207/kg (US$1 769/oz) in Q4FY21 and a 1% increase in gold production of 12 868kg (413 714oz) for Q1FY22 compared to 12 786kg (411 078oz), resulted in a 3% growth in gold revenue to R10 959 million (US$749 million) from R10 531 million (US$746 million) in the previous quarter. Despite the increase in tonnes milled, underground grade declined by 3% to 5.27g/t from the 5.44g/t achieved in the previous quarter. This was primarily a result of the safety incidents which occurred and impacted particularly the high grade panels at Mponeng, as the affected area was temporarily closed for further investigation. Moab Khotsong and the Tshepong Operations were also impacted following the safety incidents at each of the mines during the reporting period. Underground yield was further impacted by a reduction in the gold recovered at the Harmony One and Target plants as a result of inconsistent flow through from the belt to the treatment section. Towards the end of the quarter this was resolved and the average recovered grade of 5.40g/t and 5.57g/t guided for the financial year 2022 will be achieved. The sequential increase quarter-on-quarter in gold production was largely due to: - a 4% increase in underground tonnes milled to 1.794 million tonnes from 1.726 million tonnes - Moab Khotsong saw a 1% increase in grade to 6.88g/t from 6.8g/t but achieved a 10% increase in production on the back of higher tonnes milled - a significantly higher contribution from Kusasalethu which saw a 39% improvement in grade to 7.39g/t and a 41% improvement in production to 1 271kg (40 864oz) from 904kg (29 064oz) - a 15% increase in production from Target 1 as grades improved by 13% from 2.97g/t to 3.35g/t - Doornkop delivered a 9% increase in gold produced at 1 097kg (35 269oz) from 1 007kg (32 376oz) in the previous quarter - a 21% increase in production from Mine Waste Solutions to 830kg (26 685oz) from 685kg (22 023oz) as well as a 22% increase in grade to 0.13g/t from 0.11g/t Operating free cash flow for Q1FY22 was down 33% to R921 million (US$63 million) compared to R1 230 million (US$87 million) for the previous three-month period ended 30 June 2021 ("the comparable period"). Operating free cash flow margin decreased from 12% in the previous comparable period to 9% for the reporting period on the back of: - a 3% decrease in average underground grade to 5.27g/t (5.44g/t at the end of June 2021) - a 15% decrease in grade at Mponeng on the back of lower volumes blasted post the safety incident and associated stoppages and an 11% decrease in recovered grade at Tshepong - incentive bonuses which were paid in this reporting period as well as the incremental wage increase on the back of the three-year wage deal - R442 million increase in services as a result of higher winter tariffs on electricity At our Papua New Guinea operations ("PNG"), Hidden Valley continues to be impacted by Covid-19 related staffing issues as vaccine hesitancy remains a large problem across PNG. While international travel isolation requirements into PNG for fully vaccinated employees is now no longer required, return travel into Queensland, Australia, now requires an additional three days' self-isolation with a third polymerase chain reaction (PCR) screen test post the two weeks' hotel quarantine which all have an impact on work rosters and production at the mine. Total tonnes mined was up by 57% compared to the previous quarter. The Hidden Valley crushing and overland conveyor circuit throughput of 1 104 556 tonnes was higher by 76% quarter-on-quarter. This is the highest since Q2FY20 and the first time since then that the total tonnes transported via the overland conveyor circuit exceeded 1 000 000 tonnes for the quarter. However, geotechnical stability of the eastern wall of the stage 6 pit and lower than planned productivity in the south end of the stage 7 cut back due to soft ground and re-cutting of walls for geotechnical stability did impact the ability to further increase production. Furthermore, the dewatering of the pit during the September 2021 quarter also adversely impacted mining volumes. Lower grade stockpiles were thus processed to supplement the ore feed and this resulted in a 39% decrease in grade from 1.78g/t to 1.08g/t and a 43% reduction in operating free cash to R149 million (US$10 million) from the R260 million (US$18 million) reported in the previous quarter. Silver production for the quarter increased by 41% to 17 358kg (558 077oz) from 12 313kg (395 882oz) on the back of the increase in tonnes milled. Harmony's AISC for the reporting period increased by 9% to R795 086/kg from R729 680/kg (an increase of 5% to US$1 691/oz from US$1 607/oz in Q4FY21). The primary driver being the reduction in underground recovered grade, specifically impacted by the safety incidents at Mponeng and Tshepong, the lower plant recoveries in the Free State province which have now been resolved and the lower grade at Hidden Valley (as we continue with stage 6 and 7 cut backs). There are however, improvements in grade at Target 1 and Kalgold, while Joel is seeing a significant improvement in volumes post the completion of the decline project, which will ensure that we meet our annual cost guidance for FY22 of R765 000/kg to R800 000/kg. The Target 1 project is anticipated to be complete in 2022 and Kalgold is also starting to see improved grades and production on the back of an increase in feed grades and milling tonnes. EXECUTIVE MANAGEMENT Phillip Tobias, Chief Operating Officer for New Business Development, Corporate Strategy and Projects will be leaving Harmony in November 2021. Beyers Nel, Chief Operating Officer for the South African operations will take over Projects and Johannes van Heerden, Chief Executive Officer for South East Asia will take over New Business Development. We would like to thank Phillip for his valuable contribution to Harmony over the past seven years and wish him well with his future endeavours. Shela Mohatla, Group Company Secretary, has joined the Group Executive Committee and is now part of the group executive management team. We would like to congratulate Shela on her appointment. WAFI-GOLPU PROJECT Harmony and our joint venture partner Newcrest Mining Limited, continue to work with the PNG Government to progress permitting of the Wafi-Golpu Project and obtain a Special Mining Lease. This included engagement with the PNG Government during the quarter regarding potential terms of a Mining Development Contract, which is required for a Special Mining Lease. As previously advised, the Governor of Morobe Province and the Morobe Provincial Government commenced legal proceedings in the National Court in Port Moresby seeking judicial review of the decision to issue the Environment Permit which was granted in December 2020. On 10 September 2021, the National Court made an interim order staying the Environment Permit pending the determination of the judicial review. However, on 15 September 2021 the State obtained leave from the Supreme Court to appeal that National Court stay order. The judicial review proceeding is now on hold until the State's appeal against the stay order is decided by the Supreme Court. These events have not impacted project and permitting activities, which continue. ANNUAL PRODUCTION, COST AND GRADE GUIDANCE Production guidance for FY22 remains unchanged and is estimated to be between 1.540Moz and 1.630Moz at an all-in sustaining cost of between R765 000/kg to R800 000/kg. Underground recovered grade is planned to be between 5.40g/t and 5.57g/t. HEDGING The Company's hedging strategy is proving to be successful as our approach to hedge more selectively supports stronger margins and cash flows. Realised overall derivative gains for the quarter amounted to R86 million (US$6 million). The average forward Rand gold price on the hedge book has now increased to R1 016 000/kg as at 30 September 2021 from R976 000kg as at 30 June 2021. CONCLUSION As a 1.6 million ounce gold producer with an exciting pipeline of projects, we will continue on our growth trajectory to benefit our stakeholders for many years to come. With a re-engineered portfolio, we are a new Harmony - committed to doing what we have always done - mining sustainably and putting our people first.
