Publication of Prospectus

Further to the announcement released on 10 July 2025, the Company is pleased to announce that the prospectus dated 28 July 2025 (the "Prospectus") in relation to the proposed admission of its ordinary shares ("Ordinary Shares") to the Equity Shares (Commercial Companies) Category of the Official List of the Financial Conduct Authority ("FCA") and to trading on the Main Market of the London Stock Exchange ("Admission") has been published today.

It is expected that: (i) Admission will take place at 8.00 a.m. on 1 August 2025; and (ii) the Ordinary Shares will be cancelled from trading on AIM at 8.00 a.m. on 1 August 2025. The last day of trading in the Ordinary Shares on AIM is therefore expected to be 31 July 2025.

JSG does not intend to raise any funds or offer any new Ordinary Shares in connection with Admission and Admission will be effected through an introduction of the Company's existing Ordinary Shares. Following Admission, the Ordinary Shares will continue to be registered with their existing ISIN of GB0004762810 and the TIDM will continue to be JSG.

The Prospectus has been approved by the FCA and will shortly be available to view on the Group's website, https://www.jsg.com/investor-relations/main-market-listing/. 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.
