CRH plc

Extraordinary General Meeting

Tuesday, 9 February 2021, at 11.00 a.m.

An EGM will be held at Stonemason’s Way, Dublin 16, Ireland at 11.00 a.m. on Tuesday, 9 February 2021, in order for shareholders to consider, and if deemed appropriate, approve the migration of CRH’s Ordinary and Preference shares held electronically in the UK-based CREST settlement system to Euroclear Bank on 15 March 2021, the simplification of CRH’s share capital by the surrender and cancellation of the Income Shares and various changes to the Articles of Association.

A shareholder circular, which sets out details of the proposed business of the EGM, is available for you to view, together with the EGM Notice and the various other documents referred to in the circular, under the “EGM Documents” tab below.

Shareholders should read the circular in its entirety, including the documents referred to therein, and consider whether or not to vote in favour of the Resolutions in light of the information contained in the Circular.

The well-being of Shareholders and our people is a primary concern for the Board and we are closely monitoring the COVID-19 situation and any advice by the Government of Ireland in relation to the pandemic. If the current (or similarly more extensive) restrictions relating to COVID-19 are in force at the time of the EGM, the Company will be required to hold the EGM as a closed meeting (i.e. not generally open to the public). For this reason, the CRH Board encourages all shareholders to vote by proxy by appointing the chairman of the meeting as their proxy to vote on their behalf. Any update announcements regarding the EGM in the context of the evolving COVID-19 situation will be made available under the “EGM Arrangements” tab below.

Shareholders who wish to appoint a proxy electronically can do so by logging into signalshares.com, selecting CRH plc and registering for the share portal. Shareholders should note that they will need to have their investor Code (found on their share certificate and on the Form of Proxy recently sent to all shareholders by post) and follow the instructions online to register.

CREST members wishing to appoint a proxy via CREST should refer to the CREST Manual.

Continued shareholder engagement remains important to the CRH Board and, accordingly, a link to a live audio-cast of the EGM will be made available to shareholders under the “EGM Arrangements” tab below in advance of the EGM. Detailed instructions on how to access the audio-cast and how to submit questions remotely are set out in the notes to the Notice convening the EGM which can be accessed under the “EGM Documents” tab below.
