HeiQ PLC

("HeiQ" or "the Company")

Result of General Meeting, Issue of Equity & Total Voting Rights

The Company announces that all Resolutions were duly passed by Shareholders at the General Meeting held today in connection with the recently announced Fundraising.

The results of the voting were as follows:

Copies of the resolutions required to be made available for inspection in accordance with LR 9.6.2 have been submitted today to the Financial Conduct Authority and will shortly be available for inspection on the National Storage Mechanism website at https://data.fca.org.uk/#/nsm/nationalstoragemechanism

Accordingly, the Company announces the issuance of 28,000,000 New Ordinary Shares and applications have been made for the 28,000,000 New Ordinary Shares to be admitted to the standard segment of the Official List and admitted to trading on the London Stock Exchange ("Admission"), comprising (i) 7,866,709 Placing Shares; (ii) 862,069 Retail Shares and (iii) 19,271,222 Convertible Loan Note Shares. Admission is expected to occur tomorrow, 14 March 2024.

Following the issue and allotment of the New Ordinary Shares the Company has 168,537,907 Ordinary Shares in issue. The Company holds no Ordinary Shares in treasury, and therefore the total number of voting rights in the Company is 168,537,907. This figure may be used by shareholders as the denominator for the calculations by which they will determine if they are required to notify their interest in, or a change to their interest in, the Company under the FCA's Disclosure Guidance and Transparency Rules.

Furthermore, the Capital Reorganisation which comprises a subdivision of each Existing Ordinary Share of 30p into one New Ordinary Share of 5 pence and one Deferred Share of 25 pence, will become effective tomorrow. This is a technical change only and does not affect the rights of any holder of Existing Ordinary Shares.

Unless otherwise defined, capitalised terms shall have the same meaning as those set out in its announcement regarding the Fundraising dated 15 February 2024.
