Breaking Down Oxford Instruments plc Financial Health: Key Insights for Investors

From a garage in Oxford in 1959 to a FTSE 250 stalwart, Oxford Instruments plc has evolved from making superconducting magnets to a diversified scientific-instrument group that reported revenue north of £500 million in the fiscal year ending 2025 and invested over £29 million in R&D in 2023 (about 6.2% of revenue); listed on the London Stock Exchange since its 1983 spin-out from the University of Oxford, the company-now led by CEO Richard Tyson since April 2023-balances institutional ownership (Artemis holds >8.4m shares) with a conservative balance sheet (debt-to-equity ~2.6% as at 31 March 2025), a global workforce of roughly 2,334 and a business model that generates recurring sales from Imaging & Analysis and Advanced Technologies (with the U.S. accounting for 26% of revenues), while strategically refocusing after the June 2025 sale of NanoScience for £60 million and aiming for net-zero Scopes 1 and 2 by 2030.
