The Company published a shareholder circular on 10 May 2023 (the “Circular”), in relation to the Company’s proposed re-domiciliation to the AIFC (Кazakhstan). The Circular includes a notice of General Meeting to be held at 11 a.m. on 30 May 2023.

All shareholders are urged to read the Circular as a whole and in its entirety and are encouraged to participate in the voting of the resolutions at the General meeting.
