BREEDON GROUP PLC

Admission to Premium Listing Segment of the Official List and to Trading on the Main Market of the London Stock Exchange and AIM Cancellation

Further to previous announcements by Breedon Group plc (the former Jersey-incorporated holding company of the Breedon group) ("Old Breedon"), Breedon Group plc (the new English-incorporated holding company of the Breedon Group) (the "Company" and together with its subsidiaries, "Breedon" or the "Group") is pleased to announce that the scheme of arrangement to introduce the Company as the new holding company to the Group (the "Scheme") has become effective.

It is expected that the ordinary shares of the Company (the "New Breedon Shares") will be admitted at 8:00am today 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"). The ordinary shares of Old Breedon will be cancelled simultaneously from trading on the AIM market of the London Stock Exchange at 8:00am today.

New Breedon Shares have only been issued pursuant to the Scheme and the Company is not offering any New Breedon Shares, nor any other securities, in connection with Admission. New Breedon Shares have the ISIN GB00BM8NFJ84 and the Company's ticker symbol will continue to be BREE.

On 16 May 2023, 81,351 Old Breedon Shares were issued in connection with the Breedon Irish SAYE Plan. In addition, a share consolidation was undertaken pursuant to the terms of the Scheme, meaning that Old Breedon Shareholders received one New Breedon Share for every five Old Breedon Shares held (with any factional entitlements being disregarded).

Therefore, at Admission, the Company's issued ordinary share capital will be 338,901,668 ordinary shares. This figure may be used by shareholders as the denominator for the calculations by which they will determine if they are required to notify their interest in, or a change to their interest in, the Company under the FCA's Disclosure Guidance and Transparency Rules.

As at close of business on 16 May 2023, there were 1,694,509,871 Old Breedon Shares in issue with a closing share price of 69.0 pence, representing a market capitalisation of approximately £1,169 million. Based on the Company's issued ordinary share capital at Admission of 338,901,668 New Breedon Shares, the implied price for each New Breedon share is approximately 345 pence (based on an equivalent market capitalisation).

Rob Wood, Chief Executive Officer, commented:

"Today marks a significant moment in Breedon's history as we celebrate our move from AIM to the Premium Listing Segment of the Official List and to trading on the Main Market of the London Stock Exchange.

"Being a member of AIM has served us well. For over a decade, AIM has provided us with access to diverse and engaged investors within a supportive community that understands the needs of entrepreneurial businesses such as Breedon. We thank them wholeheartedly for their support.

"As an established business with a track record for growth and value creation, we believe the move to the Main Market will support Breedon in the delivery of our long-term strategy and offers an appropriate listing for a company of our scale and heritage. We look forward to our future as a Main Market company.

"This would not have been possible without the hard work and determination of everyone at Breedon, and I would like to thank all of my colleagues for their continued support."
