Audit opinion
Unqualified (clean)
Going concern
Affirmed

“The Directors believe that Denso Marston Ltd will have sufficient cash and borrowing facilities for at least the next 12 months from the date of signing this report. The Directors believe that, having considered uncertainties and reviewed cash flow forecasts for this period which allow for appropriate downside sensitivities, Denso Marston Ltd has adequate debt facilities in place with the Group to cover its requirements. In forming this judgement, the Directors have considered a downside scenario of sales 15% lower than forecast. They believe the Company is a going concern based on the existence of future business and continued financial support being made available from DENSO Group. The Directors have a letter of support from DENSO Group. Accordingly, they continue to adopt the going concern basis of accounting in preparing the financial statements.”

Year-on-year

FY2024 → FY2025 · period ending 2025-03-31 vs 2024-03-31

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
