Transaction in Own Shares

Oxford Instruments announces that, in accordance with the terms of its share buyback programme announced on 25 June 2025 (the “Share Buyback Programme”), the Company purchased the following number of its own ordinary shares of 5p each through Numis Securities Limited (“Deutsche Numis”) for cancellation at an average price of 1866.9239 pence per share:

Date of purchase:	26 September 2025
Aggregate number of ordinary shares purchased:	22,774
Lowest price paid per share (GBp):	1832.0000
Highest price paid per share (GBp):	1882.0000
Volume weighted average price paid per share (GBp):	1866.9239

Subject to settlement of the above purchases and cancellation of the purchased ordinary shares, the Company’s total number of ordinary shares in issue shall be 56,982,600. The Company holds no shares in treasury and therefore the total number of voting rights in the Company will be 56,982,600. This figure for the total number of voting rights may be used by shareholders as the denominator for the calculations by which they will determine if they are required to notify their interest in, or a change to their interest in, the Company under the FCA’s Disclosure Guidance and Transparency Rules.
