("GBG", "Group" or the "Company")

Publication of Prospectus

GBG, a global identity technology business enabling safe and rewarding digital lives, 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 Equity Shares (Commercial Companies) Category of the Official List of the Financial Conduct Authority and to trading on the main market for listed securities of London Stock Exchange plc ("LSE") (together, "Admission").

It is expected that: (i) Admission will take place at 8.00 a.m. on 30 October 2025; and (ii) the Ordinary Shares will be cancelled from trading on AIM, a market operated by the LSE, at 8.00 a.m. on 30 October 2025. The last day of trading of the Group's Ordinary Shares on AIM is therefore expected to be 29 October 2025.

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 GB0006870611 and the TIDM will remain GBG.

The Group's shareholders should consult their own professional advisers regarding the consequences of Admission.

The Prospectus has been approved by the FCA and will shortly be available to view on GBG's website, www.gbgplc.com/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.
