SHARE BUYBACK PROGRAMME

Smith Group plc ("Smiths" or the "Company") announces that, in connection with the recently announced £1 billion share buyback programme (the "Programme"), Smiths will shortly commence the first tranche of the Programme to purchase ordinary shares in the capital of the Company (the "Ordinary Shares") with a value of up to £600 million, subject to remaining within the Company's general authority to repurchase Ordinary Shares granted by its shareholders at its Annual General Meeting (AGM) on 19 November 2025 (the 2025 AGM authority is for a maximum of 32,653,430 shares). The Programme which will commence when the current £350 million buyback completes is expected to be substantially completed by the end of calendar year 2026 with the first £600 million tranche completing by 31 July 2026. The purpose of the Programme is to reduce the share capital of Smiths and therefore the Ordinary Shares purchased under the Programme will be cancelled.

The Company has entered into an agreement with HSBC Bank plc ("HSBC") under which it has issued an instruction to HSBC to manage the first tranche of the Programme. HSBC will carry out the instruction through the acquisition of Ordinary Shares in the Company for subsequent repurchase and cancellation by the Company. This arrangement is in accordance with the Company's general authority to repurchase Ordinary Shares, Chapter 12 of the Financial Conduct Authority's Listing Rules, Article 5(1) of Regulation (EU) No. 596/2014 (as incorporated into UK domestic law by the European Union (Withdrawal) Act 2018) and Commission Delegated Regulation (EU) 2016/1052 (as incorporated into UK domestic law by the European Union (Withdrawal) Act 2018).
