Share Buyback Programme

25 March 2026 - QinetiQ Group plc ("QinetiQ" or the "Group") confirms the completion by Deutsche Bank AG, London Branch (trading for these purposes as Deutsche Numis) ("Deutsche Numis") of the latest £50 million tranche of its share buyback programme, as announced on 17 November 2025.  This was the second 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 third tranche of the £200 million Programme, with a maximum aggregate value of up to £50 million (the "Third Tranche"). Under the Third Tranche, which is expected to complete by no later than 30 September 2026, Deutsche Numis will make trading decisions independently of QinetiQ in accordance with certain pre-set parameters. The Third Tranche will be effected under the authority granted by shareholders at QinetiQ's Annual General Meeting held on 17 July 2025 (the "2025 Authority"), and any subsequent authority granted at QinetiQ's 2026 Annual General Meeting.  The maximum remaining number of shares that may be repurchased pursuant to the 2025 Authority is 36,713,640 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.

Additionally, QinetiQ also announces that it intends to make use of the FCA's updated notification deadline under UKLR 9.6.6R, which permits post-trade notifications of purchases of own shares to be made no later than the end of the seventh daily market session following the date of execution. Accordingly, the Company expects to move from daily to weekly market notifications in respect of shares purchased under the Programme.
