Going concern

Affirmed

“The Directors have a reasonable expectation that the Company has adequate resources to continue in operational existence for the foreseeable future. In addition, the Company has received a letter of support from Science Group plc which evidences the intent of the parent to continue to provide financial support. Based on the work we have performed, we have not identified any material uncertainties relating to events or conditions that, individually or collectively, may cast significant doubt on the company's ability to continue as a going concern for a period of at least twelve months from when the financial statements are authorised for issue.”

Significant events

• “The MOD audit of years 2022 and 2023 completed in March 2025, any revenue uplift from which will be recognised in the 2025 Financial Statements.”

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
