**Embedded sustainability drives Harmony's MSCI ESG Ratings upgrade to 'A'**

**Johannesburg, Wednesday, 29 April 2026.** Harmony Gold Mining Company Limited ("Harmony" or the "Company") is pleased to announce that MSCI has upgraded the Company's environmental, social and governance (ESG) rating from 'BB' to 'A' following its most recent assessment in March 2026.

MSCI ESG ratings measure companies' resilience to long-term, financially relevant ESG risks. These ratings analyse industry-specific risks, management quality and controversies to identify potential impacts on a company's financial performance.

This improvement reflects our strengthened performance across key ESG pillars, underpinned by measurable progress in water management, toxic emissions and waste reduction and enhanced governance practices. Notably, our environmental pillar score improved from 3.0 to 5.1, while our social score improved from 2.4 to 4.7, demonstrating tangible progress in operational efficiency, employee engagement and community relations. Governance remains a core strength, with a consistently high score of 7.4.

*"This upgrade to an 'A' rating by MSCI is a strong endorsement of the progress we have made in embedding sustainability into every aspect of our business. It reflects the dedication of our people, the resilience of our operations and our unwavering commitment to creating long-term value for all stakeholders while responsibly managing our environmental and social impacts,"* says CEO, Beyers Nel.

------

The upgrade underscores Harmony's commitment to sustainability, transparency and responsible mining practices, aligning with our long-term decarbonisation and stakeholder engagement strategies. We continue to integrate ESG considerations into our strategic objectives, reinforcing our accountability to investors, employees and our communities.

Ends.
