Audit opinion
Unqualified (clean)
Going concern
Affirmed

“In making their assessment of going concern, the Directors have considered the Company's financial position, cash flow forecasts and its inter-dependency with the wider Smiths Group, together with the proposed sale of the Smiths Detection business to funds advised by CVC Capital Partners. Based on this assessment, the Directors consider it appropriate to prepare the financial statements on a going concern basis and do not consider that there are any material uncertainties which would cast significant doubt on the Company's ability to continue in operational existence.”

Year-on-year

FY2024 → FY2025 · period ending 2025-07-31 vs 2024-07-31

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
