IMPORTANT NOTICE

Measures to minimise any risk of Coronavirus (COVID-19) transmission at the Annual General

Meeting to be held on Thursday 23 April 2020

The well-being of attendees, employees and service providers at the upcoming Annual General Meeting ("AGM") is a primary concern for the CRH Board and in this context we are closely monitoring developments in relation to the Coronavirus (COVID-19).

Given the restrictions announced by the Government to reduce the spread of COVID-19, we strongly encourage all shareholders to submit proxy forms to ensure they can vote and be represented at the AGM without having to physically attend the meeting.

AGM Arrangements

The AGM remains scheduled to proceed on 23 April 2020, but shareholders should now expect it to take place under very constrained circumstances. As the planned AGM venue is unlikely to be available, shareholders should expect the meeting to be adjourned to the Company's Registered Office at 42 Fitzwilliam Square, Dublin 2, Ireland so that it may proceed in accordance with any prevailing restrictions at a time later in the day. Due to the current restrictions on gatherings it is expected that the meeting will only be able to proceed with the minimum number of shareholders required to establish a quorum under the Articles of Association.

Before the AGM, a shareholder may submit a question in writing, to be received at least four business days before the meeting (i.e. 17 April 2020) by post to the Company Secretary, CRH plc, 42 Fitzwilliam Square, Dublin 2, Ireland or by email to [e-mail]. All correspondence should include sufficient information to identify a shareholder on the Register of Members, for example, an IVC number, which is an 11 digit unique identifier printed on the enclosed proxy form.

Shareholders should monitor the Company's website, www.crh.com/investors/shareholder-centre/agm/for update announcements regarding the AGM in the event that circumstances change.

Shareholders are encouraged to keep up to date with the advice and guidance of the Government of Ireland and the Health Service Executive in relation to COVID-19
