Commencement of Third Tranche of Buyback Programme

3 February 2025 - QinetiQ Group plc ("QinetiQ" or the "Group") confirms the completion by Numis Securities Limited ("Deutsche Numis") of the second tranche of its £100 million share buyback programme (the "Programme") announced on 16 January 2024.  As announced on 14 November 2024, QinetiQ is extending the Programme by £50m to deliver increased shareholder returns.

QinetiQ has today entered into an agreement with Deutsche Numis to extend the Programme through the execution of a third tranche ("the Third Tranche) with a maximum aggregate value of up to £50 million. Under the Third Tranche, which is expected to complete by no later than 30 June 2025, 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 18 July 2024, and the maximum remaining number of shares that may be repurchased under the Third Tranche pursuant to that authority is 42,778,600 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.
