Trading Statement for six months ended 30 June 2026

LONDON, 25 SEPTEMBER 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 interim results for the six months ended 30 June 2026.

David Lovett, Interim CEO of Gemfields, commented:

"Further to our operational update for the six months to 30 June 2026, published on 30 July, we are pleased to provide this trading statement ahead of the release of our Interim Results.

The first half of 2026 was a challenging period for Gemfields, driven by lower-than-expected premium ruby recoveries at MRM, which had a significant impact on the Group's financial performance. Management's primary focus has been to understand the causes of these lower recoveries and implement measures to improve grade performance, mine planning and operational reliability.

While further evidence is required before drawing firm conclusions, we are encouraged by the early signs emerging from these initiatives. PP2 has now demonstrated its ability to achieve, and on occasion exceed, design throughput levels, although final commissioning and optimisation activities are still underway. Additionally recent ruby recoveries have shown early signs of improvement. Kagem, meanwhile, delivered solid operational performance and good premium emerald recoveries during the period, albeit against a backdrop of elevated operating costs.

Our priority for the remainder of 2026 is to demonstrate that the recent improvements at MRM can be sustained, while maintaining financial discipline and flexibility across the Group."

Expected revenues and net profit

Gemfields' two key operating assets, Montepuez Ruby Mining ("MRM") and Kagem Mining ("Kagem"), generated revenues of USD 76.1 million and USD 26.7 million respectively in the six months to 30 June 2026 (2025 H1: MRM - USD 38.9 million; Kagem - USD 21.1 million). Total auction revenues for the period were USD 102.8 million. Auction revenues were significantly higher than the prior period, reflecting the deferral of a mixed-quality ruby auction from December 2025 to February 2026, which reduces the comparability of the respective periods.

Gemfields is reasonably certain that its net loss after tax¹ will be USD 73.5 million for the six months ended 30 June 2026 (2025 H1: net loss after tax of USD 20.5 million). In ZAR terms, the net loss after tax is expected to be ZAR 1,205.8 million (2025 H1: net loss after tax ZAR 363.2 million).

The expected net loss after tax was driven primarily by a non-cash impairment charge of USD 125.2 million recognised in respect of MRM. In addition, the FY2025 impairment has been restated from USD 35.0 million to USD 65.0 million following the identification of a USD 30.0 million adjustment. Further details of the restatement will be provided in the interim financial statements.

The impairment reflects the more conservative approach to forecasting grade recoveries taken in the period, particularly for premium product, following lower-than-expected recoveries during the period. While uncertainty remains, recent operational performance indicates that premium-grade recoveries are beginning to improve following actions taken by management. The Group will continue to monitor grade recoveries closely as additional production data becomes available.

Expected loss per share and headline loss per share

Loss per share² is expected to be USDc 4.3 for the first six months of the year (2025 H1: loss per share - USDc 1.7). In ZAR terms, the loss per share is expected to be ZARc 70.55, representing an increase in the loss of ZARc 40.43 per share compared with the loss per share of ZARc 30.12 in 2025 H1.

Headline earnings per share² is expected to be USDc 0.6 (2025 H1: Headline loss per share - USDc 1.5). In ZAR terms, headline earnings per share is expected to be ZARc 9.84, representing an improvement of ZARc 36.44 per share from the headline loss of ZARc 26.60 reported in 2025 H1.

Adjusted headline earnings per share², is expected to be USDc 0.6 (2025 H1: loss per share USDc 1.5). In ZAR terms, adjusted headline earnings per share is expected to be ZARc 9.84, representing an improvement of ZARc 36.44 per share from the adjusted headline loss of ZARc 26.60 reported in 2025 H1.

The Company's weighted average shares in issue for the six months ended 30 June 2026 was 1,724,230,526 (weighted average for 2025 H1: 1,224,967,113).
