CRH PUBLIC LTD CO

Evaluation of Disclosure Controls and Procedures

Management has evaluated the effectiveness of the design and operation of the disclosure controls and procedures as defined in Securities Exchange Act Rule 13a-15(e) as of March 31, 2026. Based on that evaluation, the Chief Executive Officer and the Chief Financial Officer have concluded that these disclosure controls and procedures were effective as of such date at the level of providing reasonable assurance.

In designing and evaluating our disclosure controls and procedures, management, including the Chief Executive Officer and the Chief Financial Officer, recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the Company have been detected.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting during our most recently completed fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
