Commencement of £25m share buyback programme

Kier Group plc ("Kier", the "Company", or the "Group"), a leading infrastructure services, construction and property group, today announces alongside its interim results for the six months ended 31 December 2025 that it will commence a share buyback programme to purchase ordinary shares of 1 pence each in the capital of the Company ("Ordinary Shares") up to a maximum consideration of £25 million (the "Buyback Programme").

The purpose of the Buyback Programme is to return capital to shareholders. The Company will hold as treasury shares any Ordinary Shares repurchased in accordance with the provisions of the Companies Act 2006.

The Company has entered into a non-discretionary agreement with Deutsche Bank AG, London Branch ("Deutsche Numis") to conduct the Buyback Programme on its behalf and carry out on-market purchases of Ordinary Shares (the "Agreement"). The Buyback Programme will commence today, 3 March 2026, and will end on the date on which the total purchase price of all Ordinary Shares purchased by Deutsche Numis pursuant to the Buyback Programme is equal to, or as close as possible to (but not exceeding), £25 million. Deutsche Numis will make trading decisions in relation to the Buyback Programme independently of, and without further instruction from, the Company. Under the Agreement, the Company has issued an irrevocable non-discretionary instruction to Deutsche Numis to manage the Buyback Programme in order that purchases of Ordinary Shares can continue during closed periods, and if and when the Company comes into possession of inside information. While the Company has launched the Buyback Programme, there is no certainty on the volume of Ordinary Shares that may be purchased or any certainty on the pace and quantum of purchases.

The Company will announce all transactions in Ordinary Shares pursuant to the Buyback Programme by no later than 7.30 a.m. on the 7th business day following the calendar day on which such transaction occurred.

At the time of this announcement, the Company's share capital comprises 452,875,390 Ordinary Shares, of these shares 10,978,468 are held in treasury, therefore, the total voting rights in the Company is 441,896,922.
