CRH (NYSE:CRH), the leading provider of building materials, today announces its intention to delist from the London Stock Exchange (LSE) its ordinary shares and 7% preference shares (the "LSE Delisting") and, subject to shareholder approval, to cancel CRH's 5% and 7% preference shares (the "Preference Share Cancellations"). The proposed Preference Share Cancellations will have no impact on the ordinary shares. CRH's primary listing has been on the New York Stock Exchange (NYSE) since September 2023. Once the LSE Delisting takes effect, CRH's ordinary shares will be solely listed on the NYSE.

Background to and Reasons for the LSE Delisting and Preference Share Cancellations

On February 18, 2026, CRH announced its intention to undertake a review of its LSE ordinary share listing as well as its preference share capital structure. As part of the review, CRH carefully considered, among other factors, the level of trading activity for its ordinary shares on the LSE as well as the additional cost, regulatory and administrative obligations arising from retaining the LSE listings and maintaining the 5% and 7% preference shares. Following completion of the review, the Board is satisfied that it is in the best interests of CRH and its shareholders to proceed with the LSE Delisting and, subject to shareholder approval, the Preference Share Cancellations.

LSE Delisting Process

CRH has requested the UK Financial Conduct Authority (FCA) to cancel the listing of its ordinary shares and its 7% preference shares on the Official List of the FCA, and to request the LSE to cancel the admission to trading of those shares on the main market for listed securities of the LSE.

For the purposes of FCA Listing Rule 21.2.17, CRH is required to give at least 20 business days' notice of the LSE Delisting. It is expected that the LSE Delisting will become effective from 8:00 a.m. (London time) on April 20, 2026, such that the last day of trading of ordinary shares on the LSE will be April 17, 2026.

Preference Share Cancellations Process

CRH today also announces the proposed cancellation of its two classes of preference shares, comprising the 7% preference shares listed on the LSE and the 5% preference shares listed on Euronext Growth Dublin (EGD). The 7% preference shares and 5% preference shares have a total par value of approximately €1.2 million ($1.4 million).

The proposed cancellations would be in exchange for a cash payment of an amount equal to 40 times the annual dividend per preference share. This reflects a value determined by reference to the annual dividend per preference share capitalized at a rate of 2.5156% or approximately 100bps below the 30-year Bund rate as of March 12, 2026. The payments would be €2.54 per share in respect of the 5% preference shares representing 200% of nominal value, and €3.556 per share in respect of the 7% preference shares representing 280% of nominal value, with both classes having a nominal value of €1.27.

CRH will seek approval for the proposed Preference Share Cancellations from ordinary shareholders at its 2026 Annual General Meeting to be held on May 7, 2026, and at separate meetings of the preference shareholders to be held on May 21, 2026. It is expected that, subject to receipt of the requisite approvals, the Preference Share Cancellations will become effective in mid-2026. The cancellation of the 5% preference shares, if implemented, will result in the cancellation of their listing on EGD.
