As a result, the Company has requested that its ordinary shares be temporarily suspended from listing on the Official List and from trading on the London Stock Exchange's main market for listed securities with effect from 7:30 a.m. on 1 May 2026, pending publication of the 2025 Accounts, following which the Company will request that the suspension be lifted.
