IMI plc

Share repurchase programme

IMI plc (the "Company") announces that, further to its announcement on 22 June 2026 confirming completion of the first £250 million tranche (the "First Tranche") of its share buyback programme of up to £500 million announced on 6 March 2026 (the "Programme"), it is today commencing the second £250 million tranche of the Programme (the "Second Tranche").

As previously announced on 29 May 2026, the Company has entered into an agreement with Deutsche Bank AG, London Branch (trading for these purposes as Deutsche Numis) ("Deutsche Numis") to manage the Second Tranche. Deutsche Numis will carry out the acquisition of ordinary shares of 28 4/7 p in the capital of the Company (the "Shares") on a riskless principal basis for subsequent repurchase by the Company. Shares purchased pursuant to the Programme will be cancelled, in order to reduce the capital of the Company. It is anticipated that the Programme will end no later than 31 December 2026.

This arrangement is in accordance with Chapter 9 of the Financial Conduct Authority's UK Listing Rule and the Company's general authority granted by shareholders at the Company's annual general meeting held on 12 May 2026, limiting purchases of Shares by the Company in the market to nearly 10% of the Company's issued share capital as at 19 March 2026 (excluding shares held in treasury), being 24,625,138 Shares. The Programme will also be effected within the parameters of the Market Abuse Regulation 596/2014/EU and the Commission Delegated Regulation 2016/1052/EU (in each case, as they form part of UK law by virtue of the European Union (Withdrawal) Act 2018 as amended from time to time, including where relevant pursuant to the Market Abuse (Amendment) (EU Exit) Regulations 2019).
