Mitie Group plc - Transaction in Own Shares

Mitie Group plc ("Mitie" or the "Group") today announces that it purchased the following number of its Ordinary Shares of 2.5p each on Exchange (as defined in the Rules of the London Stock Exchange) from Peel Hunt LLP pursuant to its Share Buyback Programme, details of which were announced on 14 October 2025.

Mitie intends to cancel the purchased shares.

Following settlement and cancellation of the above purchase of ordinary shares of 2.5 pence each, Mitie will have 1,312,191,629 ordinary shares of 2.5 pence each in issue (excluding 1,993,865 ordinary shares of 2.5 pence each held in treasury). This figure represents the total number of voting rights in Mitie.

In accordance with Article 5(1)(b) of Regulation (EU) No 596/2014 (as such Regulation has become part of domestic law by virtue of and for the purposes of the European Union (Withdrawal) Act 2018 (as amended by the European Union (Withdrawal Agreement) Act 2020) and as such Regulation has been amended in such form by any regulations made under that Act), the schedule below contains detailed and aggregated information of the individual trades made by Peel Hunt LLP as part of the buyback programme. This announcement is made in accordance with the requirements of Listing Rule 9.6.6.

In line with the recent change to UK Listing Rule 9.6.6 concerning the timing of notifications of share repurchases, the Company will be moving from daily announcements to a consolidated weekly announcement. The Company will publish an RNS announcement each week setting out all share purchases executed on trading days during the preceding week, presented in both aggregated and detailed form consistent with the current disclosure content. For the avoidance of doubt, the amendments to the UK Listing Rules relate solely to the timing of announcements and do not affect the information required in such announcements.
