In addition, the Company needs more time to prepare the information and documents requested by the auditors for the audited annual results ("2020 Audited Annual Results") for the year ended 31 December 2020 so that the completion of annual audit of the Group by the auditors will be delayed. Accordingly, the announcement of the 2020 Audited Annual Results and the despatch of the corresponding annual report of the Company will not be ready by 31 March 2021 and 30 April 2021, respectively, as required under the Listing Rules. The Company expects that the 2020 Audited Annual Results can be published by 30 June 2021.
