Change in Total Voting Rights

Harena Rare Earths Plc (LSE: HREE) (OTCQB: CRMNF), the rare earths company focused on the Ampasindava ionic clay rare earth project in Madagascar (the "Ampasindava Project"), announces the issue of new ordinary shares to complete the £450,000 investment into the Company by RAB Capital Holdings Limited and associates ("RAB Capital").

On 1 October 2025, the Company announced a conditional subscription (the "Subscription") by RAB Capital for 30,000,000 new ordinary shares of £0.005 each in the Company (the "Subscription Shares") at a price of £0.015 per Subscription Share. The proceeds from the subscription were received by the Company in October 2025 pursuant to the Subscription Agreement and following the passing of the requisite resolutions by shareholders at the Company's annual general meeting on 4 December 2025 and with the new Prospectus Rules coming into effect, the Company will now proceed with the issue of the Subscription Shares to RAB Capital.

Accordingly, an application has been made by the Company for the 30,000,000 Subscription Shares to be admitted to trading on the main market of the London Stock Exchange ("Admission") and Admission is expected to take place at 8.00 a.m. on or around 20 January 2026.

Following Admission RAB Capital is expected to hold 58,250,959 ordinary shares of £0.005 each in the Company, representing approximately 9.8 per cent of the Company's then issued share capital.

Total voting rights

Immediately following Admission, the Company will have 592,651,018 ordinary shares of 0.5 pence each in issue, each with one voting right. There are no shares held in treasury. Therefore, the Company's total number of ordinary shares in issue and voting rights will be 592,651,018 and this figure may be used by shareholders from Admission as the denominator for the calculations by which they will determine if they are required to notify their interest in, or a change to their interest in, the Company under the FCA's Disclosure Guidance and Transparency Rules.
