Dear Shareholder,

You will find set out on pages 3 to 7 of this document the Notice convening the Annual General Meeting of the Company (the "Meeting") to be held at the Royal Marine Hotel, Marine Road, Dun Laoghaire, Co. Dublin at 11.00 a.m. on Thursday, 27 April 2023.

Business Of Meeting

The business to be transacted at the Meeting is set out in Resolutions 1 to 10 in the Notice of Meeting, details of which are set out below and in the Directors' Report on pages 134 to 138 of the 2022 Annual Report and Form 20-F (the "Annual Report") and in the notes accompanying the Notice of Meeting.

Re-election of Directors

The names of the Directors seeking re-election at the Annual General Meeting are set out in resolution 4 on page 3. The biographies of the Directors as at 1 March 2023, the date on which the Annual Report was approved, are set out on pages 82 to 84 of the Annual Report, which also includes a summary of competencies that are important to the long-term success of the Group on page 100.

Ms. C. Verchere was appointed to the Board on 20 March 2023 and is seeking re-election at the Meeting. Ms. Verchere, a dual British and United States citizen, is Chief Executive Officer of OMV Petrom S.A. (OMVP), a position she has held since 2018. OMVP is the largest integrated energy company in Southern and Eastern Europe and is active across the energy value chain from oil and gas production to power generation and supply. Prior to joining OMVP, Ms. Verchere spent over 20 years working with BP plc, a leading multinational oil and gas company, where she held a variety of senior leadership positions in the UK, the US, Canada and Indonesia, including Regional President, Asia Pacific and Regional President, Canada. Ms. Verchere holds a Master's Degree in Economics Science from the University of Aberdeen, Scotland.

We consider the current size and composition of the Board to be within a range which is appropriate. The spread of nationalities of the Directors reflects the geographical reach of the Group and we consider that the Board as a whole has the appropriate blend of skills, knowledge and experience, from a wide range of industries, regions and diverse backgrounds, necessary to lead the Group.

Membership of CRH Board (as at 21 March 2023)

I have evaluated the performance of each Director over the past year and am satisfied that each is committed to their role, provides constructive challenge and devotes sufficient time and energy to contribute effectively to the performance of the Board. I, therefore, recommend that Shareholders vote in favour of the re-appointment of each Director seeking re-election.

Meeting Arrangements / Voting

The Meeting will take place at the Royal Marine Hotel, Marine Road, Dun Laoghaire, Co. Dublin at 11.00 a.m. (Irish time) on Thursday, 27 April 2023, and shareholders have the right to attend, speak and ask questions at the Meeting.

Shareholders who cannot attend in person are encouraged to appoint a proxy to attend and vote on their behalf. Such shareholders can also submit questions in writing in advance of the Meeting, to be received at least two business days before the meeting by post to the Company Secretary, CRH plc, 42 Fitzwilliam Square, Dublin 2, Ireland or by email to mail@crh.com. Further details on how to submit proxies and ask questions in advance of the Meeting are included in the notes accompanying the Notice of Meeting on pages 5 to 7. Please check the Company's website in advance of the Meeting in case there are any changes made to the arrangements for the Meeting.

Electronic Communications

CRH plc offers shareholders the facility to receive email notifications and alerts when certain documents, such as the Annual Report and Meeting Notices, are available electronically. Registering for this facility is very straight forward and can be done through the Registrar's website, www.signalshares.com, by selecting CRH plc and following the online instructions. The benefit of registering for electronic communications is that shareholders receive notice of important information / documentation as soon as it is available and avoid any risk associated with potential postal delays. It also helps the environment by reducing the amount of paper used to communicate with shareholders and reduces the associated printing, mailing and distributions costs of the Company.

Recommendation

The Board of Directors believes that the Resolutions to be proposed at the Meeting are in the best interests of the Company and its Shareholders as a whole and, therefore, unanimously recommends that you vote in favour of each of the Resolutions, as they intend to do so themselves in respect of all of the 224,107 Shares (representing approximately 0.03% of the issued ordinary share capital of the Company on 21 March 2023) held or beneficially owned by them.

Yours faithfully,

R. Boucher Chairman

Notes

• (1) For the purposes of Section 1373(4), the Directors' Report for the year ended 31 December 2022 includes the Governance Appendix (available on the CRH website, www.crh.com), a copy of which will be appended to the Directors' Report laid before the 2023 Annual General Meeting for consideration by Shareholders.
• (2) The final dividend, if approved, will be paid on the Ordinary Shares on 4 May 2023 to persons who were registered as Shareholders at the close of business on 17 March 2023.
• (3) Resolution 3 is an advisory resolution and is not binding on the Company.
• (4) In accordance with the provisions of the UK Corporate Governance Code, all Directors retire with those eligible offering themselves for re-election.
• (5) Section 383 of the Companies Act 2014 provides for the automatic re-appointment of the auditor of an Irish company at a company's annual general meeting unless the auditor has given notice in writing of his unwillingness to be re-appointed or a resolution has been passed at that meeting appointing someone else or providing expressly that the incumbent auditor shall not be re-appointed. The Auditors, Deloitte Ireland LLP, are willing to continue in office. However, the Directors believe that it is important that Shareholders are provided with an opportunity to have a say on the continuation in office of Deloitte Ireland LLP and have included Resolution 6, which is an advisory non-binding resolution, for this purpose.
• (6) The authority in Resolution 7 is for an amount which represents just under 50% of the issued ordinary share capital as at 1 March 2023. Any allotment exceeding 33% of the issued share capital will only be made pursuant to a fully pre-emptive issue and no issue of shares will be made which could effectively alter control of the Company without prior approval of the Company in General Meeting.

In November 2022, the Pre-Emption Group published a revised Statement of Principles (the "PEG Principles"), which increased the guideline threshold for the annual disapplication of pre-emption rights authorities from 10% to 20% of a company's issued share capital, with some additional flexibility for follow-on offers of up to a maximum of an additional 4% of a company's issued share capital in specified circumstances. However, the Board has decided to seek authority under Resolution 8 for the disapplication of pre-emption rights only up to a maximum of 10% of the Company's issued share capital on an unrestricted basis in 2023, and will keep this under review in future years. Resolution 8 reflects the PEG Principles and related templates, and is in line with the authorities received by the Company in prior years. If the Company issues shares non-pre-emptively for cash, it will follow the shareholder protections in Part 2B of the PEG Principles. The 10% limit in paragraph (a) of Resolution 8 includes any Treasury Shares reissued by the Company while the authority in Resolution 8 remains operable.

• (7) Any member entitled to attend, speak, ask questions and vote at the Annual General Meeting may exercise his or her right to vote by appointing one or more proxies. A member may appoint the Chairman or another person, who need not be a member(s) of the Company, as a proxy, by electronic means or in writing, to attend, speak and vote instead of him / her and to vote some or all of their shares. Appointment of a proxy does not preclude members from attending, speaking and asking questions at the Meeting should they subsequently wish to do so. Please note that proxies may be required to provide identification to attend the Meeting.
• (8) The process for appointing a proxy and/or voting in connection with the Resolutions to be proposed at the Meeting depends on the manner in which you hold your Shares. You can exercise your right to vote in the following ways:
  • 1. If you are a certificated shareholder, by attending the Meeting in person or by appointing (either electronically or by returning a completed Form of Proxy) the Chairman of the Meeting or another person as a proxy to vote on your behalf;
  • 1. If you hold your interests in the Company's Shares through a participant account in the Euroclear Bank System (the "EB System") by (i) sending electronic voting instructions to Euroclear Bank via SWIFT or to EasyWay Corporate Actions; or (ii) sending a proxy voting instruction to Euroclear Bank to appoint a third party (other than Euroclear Nominees Limited (i.e. the nominee of Euroclear Bank) ("Euroclear Nominees") or the Chairman of the Meeting) to attend and vote at the Meeting. There is no facility to offer a letter of representation or to appoint a corporate representative other than through submission of third party proxy appointment instructions; or
  • 1. If you hold your interests in the Company's Shares as CREST Depositary Instruments ("CDIs") in the CREST system by (i) sending electronic voting instructions to Euroclear Bank via Broadridge Financial Solutions Limited ("Broadridge"); or (ii) appointing a proxy via the Broadridge Global Proxy Voting service. There is no facility to offer a letter of representation/appoint a corporate representative other than through the submission of third-party proxy appointment instructions through Broadridge.

The information set out in the Notice of Meeting in respect of voting procedures for persons who hold their interests in the Shares of the Company as Belgian law rights through the EB System or as CDIs is for guidance only and such persons should consult with their stockbroker or other intermediary at the earliest opportunity for further information on the processes and timelines for submitting proxies and voting instructions for the Meeting through the respective systems. For voting services offered by custodians holding Irish corporate securities directly with Euroclear Bank, please contact your custodian. 5
