Trading Statement for the year ended 31 December 2025

LONDON, 24 MARCH 2026

In accordance with paragraph 6.26 of the JSE Listings Requirements, Gemfields shareholders are advised that the Company is reasonably certain of its expected financial results for the year ended 31 December 2025.

Sean Gilbertson, CEO of Gemfields, commented:

"Further to our operational update for the twelve months to 31 December 2025, which was published on 30 January 2026, we are pleased to provide this trading statement ahead of the release of our annual results on Thursday 26 March 2026.

It has been a difficult year. The well documented operational interruptions at both Montepuez Ruby Mining ("MRM") and the Kagem emerald mine ("Kagem") weighed on output and cash generation. The delays to MRM's second processing plant, PP2, combined with high levels of illegal mining and grade volatility, restricted premium ruby production and disrupted our auction cadence. While it has been producing rubies since September 2025, the delay in the final commissioning of PP2 is expected to continue well into the first half of 2026.

Auction outcomes during the year were mixed. We held seven auctions realising only USD 129 million, with demand uneven and skewed away from lower‑quality, smaller‑size goods. While overall sentiment was fragile and volatility persisted, we have been encouraged by improved pricing throughout the year for high-quality emeralds and rubies. Cash generation was constrained despite disciplined cost control and a strong safety performance.

The recent escalation of conflict in the Middle East adds further uncertainty to global energy markets. While diesel prices remain volatile, it is too early to quantify any potential cost impact on our operations; however, we continue to monitor developments closely.

Our priorities for 2026 are clear: stabilise operations, ramp PP2 up methodically to nameplate capacity, continue strict cost and capital discipline, and restore a predictable auction cadence. The need to further strengthen our balance sheet means that deleveraging is the primary focus of our capital discipline in the short term, with a view to providing us with the opportunity to broaden our capital allocation options in the medium term."
