Audit opinion
Unqualified (clean)
Going concern
Material uncertainty disclosed

“The Directors, having made due and careful enquiry, are of the opinion that the Company has or will have access to sufficient funding in order to execute its operations over the next 12 months, however a material uncertainty exists. The Directors have made an informed judgment, at the time of approving the financial statements, that there is a reasonable expectation that the Company has adequate resources to continue in operational existence for the foreseeable future, however this relies upon the Company raising additional capital. As a result, the Directors have adopted the going concern basis of accounting in the preparation of the annual financial statements.”

Year-on-year

FY2023 → FY2024 · period ending 2024-12-31 vs 2023-12-31

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
