Delay to announcement of preliminary results for FY2024/25

Oxford Instruments plc, a leading provider of high technology products and services to industry and scientific research communities, today announces that there will be a delay to the publication of its preliminary results for FY2024/25, previously scheduled for today (10 June). The delay arises as a result of the Group's auditors, BDO LLP requesting further time to complete its standard audit procedures.

The results will be announced at the earliest possible opportunity.

As announced in the full year trading update on 15 April, the Group delivered a strong performance in line with market expectations.

The presentation to analysts which was due to take place today will be rescheduled.
