Update of information regarding the condition of the Tender Offer and the Company’s accession to the shareholders’ agreement

The Management Board of Polenergia S.A. (“Issuer” or “Company“), with reference to current report 20/2026 of 16 June 2026, hereby informs that on 13 August 2026 it received information that the total number of the Issuer’s shares covered by subscriptions in the voluntary tender offer for subscription for the sale of the Issuer’s shares announced on 10 July 2026, including the shares already held by Mansa Investments sp. z o.o. with registered office in Warsaw and BIF IV Europe Holdings Limited with registered office in London (“Offeror“) did not reach the threshold representing at least 95% of the total number of votes in the Company.

In view of the fact that this condition has not been met, no accession agreement was entered into pursuant to which the Company would have become a party to the shareholders’ agreement entered into by the Offerors on 3 November 2020 (as amended).

Legal basis: Article 17(1) of the Regulation (EU) No. 596/2014 dated 16 April 2014 of the European Parliament and of the Council on market abuse and repealing Directive 2003/6/EC of the European Parliament and of the Council and Commission Directives 2003/124/EC, 2003/125/EC and 2004/72/EC, as amended.
