This brings total cash returned to shareholders under our ongoing share buyback program to $10 billion since its commencement in May 2018.

CRH today also announces that it has entered into an arrangement with HSBC Securities (USA) Inc. to independently conduct a buyback program to repurchase ordinary shares listed on the New York Stock Exchange on CRH's behalf for an aggregate maximum consideration of up to $0.3 billion (the "Buyback").
