The Company announces that it is satisfied that all inside information which the directors and the Company may have in the period leading up to the announcement of the Annual Financial Report for the year ended 31 December 2023 has been notified to a Regulated Information Service (RIS).

If, in the period leading up to the announcement of the Annual Financial Report, the directors of the Company come into possession of any inside information, this will be notified to a RIS before any such transactions are undertaken.

The closed period will last until the Annual Financial Report in respect of the year ended 31 December 2023 is published, which is expected to be on or around 28 March 2024.
