CONVENING NOTICE TO THE EXTRAORDINARY GENERAL MEETING OF SHAREHOLDERS OF COAL ENERGY S.A.

Luxembourg, 10 July 2024

Dear Shareholders,

Due to the exceptional political and military circumstances in Eastern Ukraine (location of Company's assets) the Company was unable to pursue the annual audit procedure for FY2023. The Company has nevertheless been able to prepare and release unaudited consolidated financial statements for the mentioned financial year.

Despite the exceptional circumstances, the Company makes every effort to comply with its legal obligations, and to respect the rights of its shareholders. The board of directors has therefore decided to convene the extraordinary general meeting of the Company on the date 31st July 2024. The extraordinary general meeting will be held even though no audited financial report has been prepared. The annual accounts of the company submitted to the shareholders for the extraordinary general meeting have been prepared by the Company on the basis of information currently available to the Company, but without independent review of an independent auditor.
