Proposed Capital Reduction and Notice of General Meeting

13 April 2022

Harbour announces that later today it will post a circular (the "Circular") to shareholders, incorporating a notice of a general meeting (the "General Meeting"), regarding a proposed capital reduction.   The General Meeting will be held at 10.30 a.m. (or as soon thereafter as the 2022 annual general meeting (the "2022 AGM") is concluded or adjourned) on 11 May 2022.

The proposed capital reduction, if approved by shareholders, would create additional distributable reserves to support Harbour's stated $200 million per annum dividend policy and provide flexibility for future dividend payments and/or share buybacks.

The process comprises: (i) the cancellation of the entire amount standing to the credit of the Company's share premium account (the "Share Premium Reduction") and (ii) the capitalisation of the entire amount standing to the credit of the Company's merger reserve by issuing B ordinary shares in the capital of the Company and the subsequent cancellation of such B ordinary shares (the "Merger Reserve Reduction"). The Share Premium Reduction and the Merger Reserve Reduction together comprise the "Capital Reduction".

The Capital Reduction is conditional upon the passing of the resolutions set out in the notice of General Meeting by the Company's shareholders, as well as approval being obtained in the Court of Session, Edinburgh (the "Court").

It is expected that the Capital Reduction, if approved by shareholders and confirmed by the Court, will create additional distributable reserves to the value of $6.3 billion.

A circular (including the notice of the General Meeting) regarding the Capital Reduction will shortly be submitted to the FCA's National Storage Mechanism and will be available for inspection on its website at https://data.fca.org.uk/#/nsm/nationalstoragemechanism. The Circular (including the notice of the General Meeting) will also be available for viewing on the Company's website at www.harbourenergy.com.
