- Affirmed
“The directors have at the time of approving the financial statements, a reasonable expectation that the company has adequate resources to continue in operational existence for the period to 30 April 2026. Thus, they continue to adopt the going concern basis of accounting in preparing the financial statements.”
Significant events

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
