- Audit opinion
- Unqualified (clean)
- Going concern
- Affirmed
“Based on the work we have performed, we have not identified any material uncertainties relating to events or conditions that, individually or collectively, may cast significant doubt on Operational Research Society's ability to continue as a going concern for a period of at least twelve months from when the financial statements are authorised for issue.”
Significant events
- “Highlights have included celebrating the 50th Anniversary of EURO at the EURO conference in Leeds in June.”
- “I was particularly proud to host the inaugural Healthcare Forum as my Presidential Initiative this year, which brought together a diverse and inclusive community of managers, policymakers, academics, researchers, and practitioners.”
- “2025 was a pivotal year for the mathematical sciences community that saw the establishment of the Academy for Mathematical Sciences and the appointment of 100 inaugural Fellows of the Academy. The Society was delighted that 11 Fellows are Operational Research Society members.”
- “This year our journals have gone from strength to strength, with article downloads now exceeding 1.39 million (a 12.46% increase compared to 2024) and citation levels rising by 5%.”
