Wednesday, 12 November 2025. Harmony Gold Mining Company Limited (Harmony or the Company) is pleased to report its operational update for the three months ended 30 September 2025. 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 three months ended 30 September 2025 1 MESSAGE FROM THE CHIEF EXECUTIVE OFFICER OVERVIEW Harmony delivered a solid operational performance in Q1FY26, driven by an improvement in safety, consistent operational excellence, higher recovered grades at Hidden Valley and a higher gold price received. We are encouraged to report a loss-of-life-free quarter – affirming that safe mines are profitable mines. As we continue Mining with Purpose, Harmony is on track to meet its FY26 production, cost and grade guidance. While gold remains our core focus, our copper expansion is a strategic move to enhance portfolio resilience, margin quality and long-term sustainability. On 24 October 2025, we completed the acquisition of MAC Copper, owner of the high-grade CSA mine in Cobar, Australia. We are delighted to welcome the CSA mine employees to Harmony. The completion of this landmark acquisition marks a significant milestone in our strategy to grow into a global gold and copper producer. Copper is essential to the global shift toward renewable energy infrastructure. Harmony's growing copper portfolio reinforces our strategic role in enabling the energy transition, while positioning us to benefit from long-term structural demand. Whether investing in our own growth projects or pursuing value-accretive mergers and acquisitions, all opportunities are assessed through a disciplined lens that weighs potential returns against associated risks. Ultimately, every project competes for capital, and we will continue to allocate resources to those initiatives that deliver the greatest value for our stakeholders. Safety The health and safety of our people remain our top priority. Our long-term improvement in our safety performance reflects the success of our proactive programmes and robust safety infrastructure. As operators of some of the world's deepest mines, we know this demands excellence at all times. We remain committed to zero harm through a culture of accountability and continuous improvement. In Q1FY26, our lost-time injury frequency rate improved to 4.29 from 5.57 in Q1FY25 – a positive trend, but the elimination of injuries and zero harm remains the goal. We continue embedding a safety-first mindset across all operations, ensuring every workplace is safe, compliant, and empowering. Other notable achievements this reporting period include: South African operations achieved 3 million loss-of-life free shifts for the period under review Five of our underground mines achieved millionaire status during the quarter, with Masimong recording over four million loss-of-life free shifts Hidden Valley has operated for over 10 years without a loss of life. Revenue and average gold price received Gold revenue for the quarter rose 20% to R21 689 million (US$1 230 million) from R18 125 million (US$1 009million) in Q1FY25, driven primarily by a 34% increase in the average gold price to R1 818 510/kg (US$3 209/oz) from R1360974/kg (US$2 356/oz). While the gold price remains outside our control, we continue to focus on factors within our influence: improving safety, maintaining disciplined mining practices, allocating capital effectively and sustaining rigorous cost management. Progress on our Thibakotsi safety strategy resulted in a loss-of-life free quarter Lost time injury frequency rate (LTIFR) at 4.29, and below 5.00 for second consecutive quarter Immediate copper production added after successful acquisition
