Proposed move to the Main Market & Trading update

Proposed move to the Main

GBG, a global identity technology business enabling safe and rewarding digital lives, today confirms that good progress has been made with respect to the workstreams required to support the Group's move to the ESCC segment of the Official List of the FCA and to trading on the Main Market of the London Stock Exchange ("Admission").

We expect Admission to occur on Thursday, 30 October 2025 at which time the trading of the Company's shares on AIM is expected to be cancelled. Accordingly, GBG hereby gives notice of the intended cancellation of trading of its ordinary shares on AIM in accordance with Rule 41 of the AIM Rules for Companies.

Admission is subject to the approval by the FCA of a prospectus and the ordinary shares being admitted by the FCA to the Official List and by the London Stock Exchange to trading on the Main Market. Admission is not conditional upon shareholder approval. Shareholders should note that the Group's shares will no longer be traded on AIM with effect from Admission and should consult their own professional advisers regarding the consequences of Admission.

Trading update

GBG confirms that trading in the year-to-date has been in line with the Board's expectations. Taken together with the current sales pipeline for the remainder of the year, the Board is confident that GBG will deliver on its full year revenue outlook, which is consistent with current market expectations.

GBG expects to publish a pre-close trading update with respect to the half-year ending 30 September 2025 on Thursday, 16 October and intends to report its first half results on Tuesday, 25 November.
