7 August 2024 - QinetiQ Group plc ("QinetiQ" or the "Group") confirms the completion by Barclays Bank plc of the first tranche of its £100 million share buyback programme (the "Programme") announced on 16 January 2024.

QinetiQ has today entered into an agreement with Numis Securities Limited ("Deutsche Numis") to complete the Programme through the execution of a second tranche ("the Second Tranche) with a maximum aggregate value of up to £55 million. Under the Second Tranche, which is expected to complete by not later than 6 February 2025, 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 18 July 2024, and the maximum number of shares that may be repurchased under the Second Tranche is 57,052,286 Ordinary Shares (the "Buyback Authority").

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.
