Further Extension to Exchange Offer Timetable

Polymetal International plc (the “Company”) announces the extension of the completion period for the exchange of certain Eligible Shares in consideration for Certificated Shares as announced in the Exchange Offer on 22 September 2022. The Exchange Offer was approved by Shareholders at the General Meeting on 12 October 2022.

Unless otherwise defined herein, defined terms have the same meaning as defined in the Exchange Offer Circular or the Re-domiciliation Circular, as appropriate.

Pursuant to the terms of the Exchange Offer set out in the combined shareholder circular and notice of General Meeting published by the Company on 22 September 2022 (the “Exchange Offer Circular”), and as set out in the announcements dated 22 September 2022, 6 October 2022 and 8 December 2022, the Company exercises its right to extend the period for exchange under the Exchange Offer.

The expected timetable for the Exchange Offer is updated as follows:

The above times and/or dates may be subject to further change by the Company and in the event of any such change, the revised times and/or dates will be notified to Shareholders by an announcement through a Regulatory Information Service.

* The earlier of (i) this date, (ii) the date that the Re-domiciliation becomes effective and, (iii) if the authority granted to Directors with respect to the Exchange Offer is not renewed at the upcoming annual general meeting of the Company (“2023 AGM”) — the date of the 2023 AGM.

The Company continues to engage with the FCA in respect of an orderly termination of the London Listing (the “London De-Listing”). For the avoidance of doubt, any London De-Listing will be subject to shareholder approval and will take effect no less than 20 Business Days from the passing of the relevant London De-listing Resolution at a General Meeting.
