CRH : Notice of Meeting and Proxy Statement for the 2024 Annual General Meeting

Letter from the Chairman

Driving further shareholder value through our integrated solutions strategy

Dear Shareholder,

I am pleased to invite you to attend the Annual General Meeting of CRH plc to be held on April 25, 2024 at 11:00 a.m. (Dublin) at the Royal Marine Hotel, Marine Road, Dun Laoghaire, Co. Dublin, Ireland (the "2024 AGM"). Details in relation to attending and voting on the Proposals on the agenda for the 2024 AGM are set out on pages 64 to 66 of this Notice of Meeting and Proxy Statement.

Performance & Strategy

CRH delivered another record result in 2023. Adjusted EBITDA* increased 15% to $6.2 billion in 2023 (2022: $5.4 billion) and Earnings per Share (EPS) increased 22% to $4.36 (2022: $3.58). Excluding the non-cash impairment charge, EPS was $4.65, 30% higher than the prior year (2022: $3.58). Our unique integrated solutions strategy, coupled with our ongoing focus on commercial and operational excellence, supported this record performance, while our strong cash generation and disciplined approach to capital allocation provides further opportunities to create value for all of our shareholders.

The total dividend per share for 2023 was increased by 5%, with the final dividend being accelerated and paid as a second interim dividend on January 17, 2024. The payment of the second interim dividend was to facilitate the Company's transition to a quarterly dividend cadence in 2024 following our transition to a primary listing on the New York Stock Exchange (NYSE) during 2023. As part of our ongoing share buyback program, we repurchased 54.9 million Ordinary Shares in 2023 (2022: 29.8 million) for a total consideration of $3.0 billion (2022: $1.2 billion). On December 21, 2023, the Company commenced a further tranche of $0.3 billion which completed on February 28, 2024 and the Board has extended the program with an additional

$0.3 billion tranche to be completed no later than May 9, 2024. We will continue to assess our share buyback program throughout 2024, with further updates on a quarterly basis. The increase in our dividend and share buyback program in 2023 demonstrates our confidence in the outlook for our business and our continued strong cash generation.

Listing Changes

At an Extraordinary General Meeting of the Company held on June 8, 2023, shareholders overwhelmingly approved the unanimous recommendation of the Board and management team to transition to a U.S. primary listing on the NYSE. Shareholders also approved the transfer of CRH's listing category of Ordinary Shares on the London Stock Exchange (LSE) from a premium listing to a standard listing. These listing changes, together with the cancellation of CRH's secondary listing of Ordinary Shares on Euronext Dublin, became effective on September 25, 2023.

North America currently represents approximately 75% of Adjusted EBITDA* and is expected to be a key driver of future growth for CRH. We believe a U.S. primary listing will bring increased commercial, operational and acquisition opportunities for our business, further accelerating our

The feedback from these meetings was also provided to the Board and relevant Committees.

Conclusion

On behalf of the Board, I would like to express our appreciation to all of our employees for their commitment and efforts during the year and to the management team led by our Chief Executive, Albert Manifold.
