Notice of AGM and form of proxy - correction

Following the announcement made on 6 June 2023 in respect of the Annual General Meeting (the "AGM") of the Company to be held on 19 July 2023, and the publication and despatch of a circular to shareholders containing notice of the resolutions to be considered at the AGM (the "Notice") and a form of proxy (the "Form of Proxy"), it has come to the attention of the Company that the Notice and the Form of Proxy each contain a typographical error.

In the Notice, Special Resolution 16 should cross-refer to resolution 15 (not 16).  In the Form of Proxy, Special Resolution 16 should cross-refer to resolution 16 (not 15).

As these are clerical errors, no new documents will be posted to shareholders, but copies of the corrected Notice and Form of Proxy are available on the following page of the Company's website: https://www.hicl.com/investors/reports-publications/

The corrected documents have also been submitted to the National Storage Mechanism and will shortly be available for inspection at: https://data.fca.org.uk/#/nsm/nationalstoragemechanism
