Enclosure: CRH Continues Share Buyback Program

Press Release

CRH Continues Share Buyback Program

CRH plc, the leading provider of building materials solutions, is pleased to announce that it has completed the latest phase of its share buyback program, returning a further $1.0 billion of cash to shareholders.

Between 25 September 2023 and 20 December 2023, 17.1 million ordinary shares listed on the New York Stock Exchange and on the London Stock Exchange were repurchased. This brings total cash returned to shareholders under our ongoing share buyback program to $7 billion since its commencement in May 2018.

CRH today also announces that it has entered into an arrangement with Citigroup Global Markets Inc. ("Citi") to repurchase ordinary shares listed on the New York Stock Exchange on CRH's behalf for an aggregate maximum consideration of $300 million (the "Buyback"). The Buyback will commence today, 21 December 2023, and will end no later than 28 February 2024. This $300 million tranche is the final stage of the wider $3 billion program announced on 2 March 2023.

Citi will conduct the Buyback on CRH's behalf and will make trading decisions under the Buyback independently of CRH in accordance with certain pre-set parameters. The maximum number of ordinary shares which may be acquired pursuant to the Buyback is 18,000,000. The purpose of the Buyback is to reduce the share capital of CRH.

The Buyback will be conducted within the parameters prescribed by (i) Rule 10b5-1 and Rule 10b-18 under the U.S. Securities Exchange Act of 1934, as amended and (ii) the EU Market Abuse Regulation (596/2014) and Commission Delegated regulation (EU) 2016/1052 as such legislation forms part of retained EU law in the United Kingdom ("UK") (as defined in the EU (Withdrawal) Act 2018) and as amended pursuant to the UK's Market Abuse (Amendment) (EU Exit) Regulations 2019 (as may be amended and/or supplemented from time to time). No repurchases will be made outside of the United States. The repurchased ordinary shares will be cancelled.

Any decision in relation to any future buyback program will be based on an ongoing assessment of the capital needs of the business and general market conditions.
