Ceres Power Holdings plc

("Ceres", the "Company")

Publication of Prospectus

Further to the announcement made on 1 June 2023, Ceres is pleased to announce the publication of a prospectus (the "Prospectus") in relation to the proposed admission of its ordinary shares (the "Ordinary Shares") to the premium listing segment of the Official List of the Financial Conduct Authority (the "FCA") and to trading on the main market for listed securities (the "Main Market") of London Stock Exchange plc (the "London Stock Exchange") (together, "Admission").

It is expected that: (i) the Ordinary Shares will be admitted to the premium listing segment of the Official List and to trading on the Main Market at 8.00 a.m. on 29 June 2023; and (ii) admission of the Ordinary Shares to trading on AIM will be cancelled at 7.00 a.m. on 29 June 2023. The last day of trading of the Company's Ordinary Shares on AIM is therefore expected to be 28 June 2023.

The Company is not offering any new Ordinary Shares nor any other securities in connection with the proposed Admission. Following Admission, the Company's Ordinary Shares will continue to be registered with their existing ISIN of: GB00BG5KQW09 and the Company's ticker symbol will continue to be CWR.

The Company's shareholders should consult their own tax advisers as to the tax implications of the Company's proposed move to the Main Market.

The Prospectus has been approved by the FCA and will shortly be available to view on Ceres' website, https://www.ceres.tech/investors/. A copy of the Prospectus will be submitted to the National Storage Mechanism and will be available for inspection at https://data.fca.org.uk/#/nsm/nationalstoragemechanism.
