Petropavlovsk PLC

Resignation of Auditor

Petropavlovsk PLC ("Petropavlovsk" or the "Company" and, together with its subsidiaries, the "Group") has been informed of the resignation of MHA MacIntyre Hudson ("MHA"), the UK member of Baker Tilly International, as the Company's external auditor. MHA had served as external auditor since September 2021.

As announced on 7 June 2022, the Board of Directors extended the Company's accounting reference date from 31 December 2021 to 28 February 2022 in order to give the Company more time to allow the completion of its audit and publish its annual report and accounts for the period ended 28 February 2022. Nevertheless, the Board at that time considered it unlikely that the Company would be able to complete the audit save in the case of a material change in circumstances. This position remains unchanged.
