(the “Company” or “Harbour”)
Share Consolidation and Total Voting Rights
25 June 2021

Further to the Company’s announcement on 23 June 2021 regarding the result of the Annual General Meeting, the Company confirms that the Share Consolidation will become effective today such that shareholders who were on the Company’s register of members at 6:00pm on 24 June 2021 will hold 1 New Ordinary Share of 0.002 pence each for every 20 Existing Ordinary Shares of 0.0001 pence each previously held.

Admission of the New Ordinary Shares to the premium listing segment of the Official List and to trading on the London Stock Exchange's Main Market for listed securities will take place at 8:00 a.m. today (or as soon as practicable thereafter).

The New Ordinary Shares will be admitted to trading under a new ISIN number: GB00BMBVGQ36

Shareholders who held their Existing Ordinary Shares in CREST prior to the Share Consolidation will have New Ordinary Shares credited to their CREST accounts as soon as practicable today. Shareholders who held their Existing Ordinary Shares in certificated form will have replacement share certificates posted to them within 10 business days.

Immediately following admission, the Company will have 925,532,606 ordinary shares of 0.002 pence each in issue; therefore, the total voting rights in the Company will be 925,532,606. This figure may be used by shareholders as the denominator for calculations by which they may determine whether or not they are required to notify their interest in, or a change to their interest in, the share capital of the Company under the FCA’s Disclosure Guidance and Transparency Rules.
