Press release 4 March 2025     O'KEY Group S.A. (AIX, MOEX: OKEY, the “Group” or the “Company”), one of Russia’s leading food retailers, announces that its Board of Directors has decided to convene a General Meeting of Shareholders to address matters related to changing the Group’s legal registration from the Grand Duchy of Luxembourg to the Russian Federation (“redomiciliation”), subject to compliance with the applicable legal and regulatory requirements. The Company will hold an Extraordinary General Meeting of Shareholders (EGM) on this matter on 25 March 2025.   In accordance with the applicable corporate procedures and legal requirements of Luxembourg, the change of jurisdiction must be approved by the General Meeting of Shareholders. If shareholders approve the redomiciliation at the EGM on 25 March 2025, and once the redomiciliation process is completed, O’KEY Group, in accordance with Russian law, will become an international public joint-stock company (IPJSC), registered in the special administrative region on Oktyabrsky Island in the Kaliningrad region, and the Company will continue to operate as a legal entity in Russia. Upon redomiciliation to the Russian Federation, all 269,074,000 Company shares will be recognised as shares of the IPJSC at a 1:1 ratio. The nominal value of the Company’s shares will be denominated in the Russian roubles, equivalent to their nominal value in euros, converted at the official exchange rate set by the Bank of Russia on the date of the EGM. The Group will provide regular updates on the redomiciliation process. Prior to finalising the redomiciliation procedure, the Company must complete all actions required by law to terminate its operations in Luxembourg. Further information will be provided on the possible timeline for redomiciliation. In the meantime, the Group will continue to operate as a Luxembourg-registered company until the redomiciliation has been completed. The process of changing the Group’s legal registration will not affect the business operations of its retail chains or its subsidiaries in Russia. The Group will continue to meet all its obligations to its partners and customers on time and in full. The EGM on the redomiciliation is scheduled for 25 March 2025, at 10:00 (CET). GDR holders registered as of 17:00 (CET) on 5 March 2025 will be able to vote after registration on the website of RCS Trust and Corporate Services Ltd (the depositary for the Group’s GDRs) at https://rcsgroup.com/signin/.
