Values shown as filed in the company's annual accounts. indicates the figure wasn't present under that line item in that period. About these numbers

Year-on-year

FY2024 → FY2025 · period ending 2025-12-31 vs 2024-12-31

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
