Share Buyback Programme

17 November 2025 - QinetiQ Group plc ("QinetiQ" or the "Group") confirms the completion by Numis Securities Limited ("Deutsche Numis") of the latest £50 million tranche of its share buyback programme, as announced on 5 June 2025. This was the first tranche of the £200m extension to its share buyback programme that was announced by QinetiQ on 17 March 2025, for execution over the following two years (the "Programme").

QinetiQ has today entered into an agreement with Deutsche Numis to execute the second tranche of the £200 million Programme, with a maximum aggregate value of up to £50 million (the "Second Tranche"). Under the Second Tranche, which is expected to complete by no later than 31 March 2026, Deutsche Numis will make trading decisions independently of QinetiQ in accordance with certain pre-set parameters. The Second Tranche will be effected under the authority granted by shareholders at QinetiQ's Annual General Meeting held on 17 July 2025 (the "2025 Authority"). The maximum remaining number of shares that may be repurchased pursuant to the 2025 Authority is 47,227,575 Ordinary Shares.

Any purchases under the Programme will be carried out on the London Stock Exchange and any other UK recognised investment exchange which may be agreed, in accordance with pre-set parameters and in accordance with the Buyback Authority, Chapter 12 of the UK Financial Conduct Authority's Listing Rules, and Regulation (EU) No 596/2014 and Commission Delegated Regulation (EU) No 2016/1052 (both as they form part of UK domestic law by virtue of the European Union (Withdrawal) Act 2018), including where relevant pursuant to the UK Market Abuse (Amendment) (EU Exit) Regulations 2019.

Any Ordinary Shares purchased pursuant to the Programme will be cancelled, and the number of Ordinary Shares in issue reduced accordingly.
