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

- Audit opinion
- Unqualified (clean)
- Going concern
- Affirmed
“The Board recognises the uncertain economic and political environment that the world faces and has reviewed the business outlook to reflect this uncertainty. Cash flow forecasts have been prepared to model various scenarios over a three-year period based on the Group's financial and trading position, principal risks and uncertainties and strategic plans. A downside scenario was modelled where programme curtailment and/or delays may adversely affect forward-looking demand to levels lower than those initially modelled in the base case scenario. The scenarios modelled above demonstrate the Group has adequate cash and borrowing capacity for the next twelve months. Therefore, the directors continue to adopt the going concern basis to prepare the financial statement”
Significant events
- “An impairment was processed in year relating to the recoverability of an intercompany receivable balance with Filtronic Wireless inc. for £617,059 (2024: £nil). This resulted in an operating loss before exceptional items of £441,134 (2024: £258,143 operating profit).”
