Audit opinion
Unqualified (clean)
Going concern
Affirmed

“The directors believe that the preparation of the financial statements on the going concern basis is appropriate. The company has sufficient cash reserves and holds no interest-bearing liabilities. Whilst current economic pressures may have an impact on defence spending throughout 2025, it does not present a going concern risk to the business as pipeline growth for core activities and order bookings in subsequent years remain robust. The directors have prepared detailed revenue and cost forecasts through to the end of September 2026, which show a continuing profitable trading performance. As a wholly owned subsidiary, the directors expect that the company could rely on the financial support of the ultimate parent company, L3Harris Technologies, Inc., if necessary. The company has received a letter of support, covering the period 12 months after the approval of the financial statements, from its ultimate parent company to this effect. The directors are satisfied that the parent is in a position to be able to provide this financial support. Thus, the directors continue to adopt the going concern basis of accounting in preparing the financial statements.”

Year-on-year

FY2023 → FY2025 · period ending 2025-01-03 vs 2023-12-29

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
