Going concern
Affirmed

“The directors have performed a going concern assessment for a period of at least 12 months from the date of approval of these financial statements which indicate, taking account of reasonably possible downsides, the Company will have sufficient funds through its funding from its ultimate parent company (Sumitomo Corporation) to meet its liabilities as they fall due for that period.”

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
