The event is being hosted in person and online, with details below.

Richard Duffy, Chief Executive at Petra, commented:

“We have worked hard to deliver an updated business profile in response to ongoing market challenges and to further enhance our resilience to future market and capital cycles. We are pleased to present a de-risked production profile focused on sustainable cash generation, having reduced costs by US$30 million annually from FY 2025 and delivering a smoothed capital programme self-funded until at least the early 2030s. In doing so, we provide a compelling value proposition, while positioning for a successful refinancing of our 2026 2L Notes.

We also announce today the appointment of Johan Snyman as CFO from October. Johan has made significant contributions to Petra since joining in January and I look forward to working with him in his new role.”

Highlights include:

• Sustainable reduction in operating costs of US$30m per annum from FY 2025
• Total capital (development and sustaining capital) profile smoothed to c.US$100m per annum at Petra’s South African operations to target free cash generation through the cycle
• Approved extension projects expected to be self-funded
• Production growth to over 3.4 Mcts expected by FY 2028
• Cullinan Mine LOM potential to FY 2048 with new shaft for D-Cut not required before 2035 (subject to further studies)
• Finsch LOM potential to FY 2038

CFO Succession

Petra is also pleased to announce the appointment of Johan Snyman as Chief Financial Officer, with effect from 1 October 2024. Johan will succeed Jacques Breytenbach who, as previously announced, will be stepping down from his position as Chief Financial Officer and Director of the Company at the end of September 2024 for personal reasons. Johan joined Petra in January 2024 as Group Financial Controller. Prior to joining, Johan was Vice President, Group Financial Reporting at AngloGold Ashanti Limited where he worked for 17 years. Johan has extensive experience in various financial roles in the mining sector. He started his career at KPMG and is a qualified Chartered Accountant with an MBA (University of Cape Town).
