- Affirmed
“The Board of Trustees / Directors are confident in their assessment of the Society as a 'going concern'.”
Significant events
- “The Events programme over the last year began with a hybrid Beale lecture and a well-attended start to a new series of one day joint SIG events with a session on Making Better Futures with Systems Approaches, with four SIGs coming together in an in-person event in Birmingham.”
- “In June we held our first New2OR event since before the pandemic. Those attending were very enthusiastic about the new format and the content.”
- “July saw another first for the Society, with a special event at the House of Lords to celebrate our 75th anniversary. The reception was held on the terrace, with a fine view along the Thames towards the London Eye and Big Ben.”
- “Continuing the new theme our ISMOR conference moved to a new venue in the National Oceanographic Centre in Southampton, with an unprecedented move to multiple sessions to accommodate demand and an outing to the Isle of Wight.”
- “The launch of Applied Operations and Analytics (AOA) in 2024 marks a significant expansion of the Society's portfolio.”
- “The WORAN Land Lecture was held in October and an inspiring talk and Q & A was given by Dervilla Mitchell DBE, FREng, FIEI on Building Change: a life in engineering.”

Each % is (latest − prior) ÷ |prior| for the line item as filed. The comparison is only shown when the latest and prior accounts cover broadly equal-length periods — short or long stubs (typical around incorporation or a year-end change) are suppressed rather than misrepresented. Lines a company doesn't report are omitted. About these numbers
