EXPLANATORY NOTE

CRH plc (together with its consolidated subsidiaries, the 'Company', 'CRH', the 'Group', 'we', 'us' or 'our'), a corporation organized under the laws of the Republic of Ireland, previously determined, as of June 30, 2024 (including as a result of more than 50% of its Ordinary Shares being held by U.S. residents), that it will no longer qualify as a foreign private issuer as defined under the U.S. Securities Exchange Act of 1934 (the 'Exchange Act'). Effective as of January 1, 2025 CRH will be considered a U.S. domestic issuer.

For fiscal year 2024, CRH has voluntarily chosen to file annual reports on Form 10-K, quarterly reports on Form 10-Q and current reports on Form 8-K with the U.S. Securities and Exchange Commission (SEC) instead of filing on the reporting forms available to foreign private issuers.
