Notice of Annual General Meeting

Petra Diamonds Limited announces that it has today published a Notice of Annual General Meeting, which is scheduled to be held on 27 November 2025.

The Notice of Annual General Meeting is available to view the Company's website at www.petradiamonds.com.

In accordance with UK Listing Rule 6.4.3R, a copy of the Notice of Annual General Meeting will be uploaded to the National Storage Mechanism and will shortly be available for viewing at https://data.fca.org.uk/#/nsm/nationalstoragemechanism.

It has come to the Company's attention that at page 65 in Part VII (Letter from the Chairman) of the prospectus published by the Company on 17 October 2025 (the "Prospectus") and in the announcement published by the Company on the same day titled "Launch of 10 for 17 fully underwritten Rights Issue and update on Refinancing", there is an incorrect reference to the Work Fee Warrants (as defined in the Prospectus) lapsing if they are not exercised by the relevant warrant-holder prior to March 2030. The Work Fee Warrants will not be subject to a lapse date, and will be able to be exercised by the relevant warrant-holders at any time following their issuance.
