Oxford Instruments plc (the “Company”)

Extension of Share Buyback Programme

Further to the announcement of 11 November 2025, Oxford Instruments plc (the “Company”), a leading provider of high technology products and systems for industry and research, announces that from today it will extend its share back programme to purchase up to an additional £50 million   of the Company's ordinary shares of   5 pence   each (the "Ordinary Shares") (the "Programme") by no later than 2 March 2027.

The purpose   of the Programme is to reduce the Company's share capital and accordingly the Company intends to cancel the Ordinary Shares purchased under the Programme however the Company may transfer some shares to Treasury to be used in relation to the Company’s employee share option plans.

Any purchases will be conducted in compliance with the relevant conditions for trading, restrictions regarding time and volume, disclosure and reporting obligations, and price conditions. The Company confirms that it currently has no unpublished Inside Information.

The Programme will be conducted by the Company in accordance with and under the terms of the general authority granted by the Company's shareholders at the Company's Annual General Meeting on   28 July 2025, which authority will expire at the end of the next Annual General Meeting of the Company in 2026 or, if earlier, at the close of business on   30 September 2026 ("2025 Authority").     Purchases effected following the expiry of the 2025 Authority will be conditional on a similar shareholder authority being granted at the Company's annual general meeting to be held on 23 July 2026.  

The Company has appointed its broker J.P. Morgan Securities plc ("JPMS plc") to manage the Programme and has issued an irrevocable instruction to J.P. Morgan pursuant to continue to manage the Programme, within pre-set parameters, during any closed period. JPMS plc shall purchase the Ordinary Shares as riskless principal (and not as agent of the Company) for the subsequent sale on to, and purchase by, the Company. JPMS plc will make its trading decisions in relation to the Ordinary Shares independently of, and uninfluenced by, the Company.

The Programme will be carried out on the London Stock Exchange and other trading venues 1   and executed within the parameters of the Market Abuse Regulation 596/2014/EU and the Commission Delegated Regulation 2016/1052/EU (as each forms part of domestic law under the European Union (Withdrawal) Act 2018, including where relevant pursuant to the Market Abuse (Amendment) (EU Exit) Regulations 2019) and Chapter 9 of the   UK   Listing Rules of the Financial Conduct Authority.

The aggregate maximum consideration payable by the Company in respect of the purchase of shares under the Programme is £50 million. The maximum number of shares that may be purchased under the Programme is 3,735,869 (being the number of shares remaining to be purchased under the 2025 Authority).
