BREEDON GROUP PLC

Publication of Prospectus

Further to its announcements made on 8 March 2023, 29 March 2023 and 26 April 2023, Breedon Group plc (the "Company" and together with its subsidiaries, "Breedon" or the "Group") is pleased to announce the publication of a prospectus (the "Prospectus") in relation to the proposed admission of the ordinary shares of the new holding company of the Group, incorporated in England and Wales ("New Breedon" and the "New Breedon Shares") to listing on the premium listing segment of the Official List of the Financial Conduct Authority (the "FCA") and to trading on the Main Market of the London Stock Exchange ("Admission").

Subject to the various conditions set out in Part 2 of the Scheme Document published by the Company on 29 March 2023 (the "Scheme Document"), it is expected that: (i) the Scheme will become effective on 16 May 2023; (ii) Admission will take place at 8.00 a.m. on 17 May 2023; and (iii) the admission of the Company's ordinary shares to trading on AIM will be cancelled by 8.00 a.m. on 17 May 2023. The last day of trading of the Company's ordinary shares on AIM is therefore expected to be 16 May 2023.

New Breedon is not offering any New Breedon Shares nor any other securities in connection with the proposed Admission. Following Admission and the Scheme becoming effective, the Company's ordinary shares will no longer be registered with their existing ISIN of JE00B2419D89. The New Breedon Shares will instead be registered with the ISIN GB00BM8NFJ84. New Breedon's ticker symbol will continue to be BREE.

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

The Prospectus has been approved by the FCA and will shortly be available to view on Breedon's website https://www.breedongroup.com/investors/aim-to-main. 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.

Upon the Scheme becoming effective, Breedon Shareholders will receive one New Breedon Share for every five Breedon Shares held at the Scheme Record Time (provided that any fraction of a New Breedon Share shall be disregarded). It is expected that, at Admission, New Breedon's issued ordinary share capital will be up to 338,905,147 New Breedon Shares.
