Audit & accounting basis
- Accounting basis

- Reporting scope
- Standalone (parent only)
- Auditor
- Ernst & Young LLP
- 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.”
Significant events
- “Revenue grew by 5.8% between 2023 and 2024. Despite this growth during the year there were significant swings across all major business areas. Catapan Encryption Product sales were down 36%, offset by new sales including £6.9M on a UK government contract for equipment manufactured and supplied by a fellow subsidiary undertaking in the USA which only generates low pass-through margins for the company.”
- “On 1 April 2021, as part of a restructure, the company acquired the net assets of a fellow subsidiary undertaking L31Harris Technologies ASA Limited ('ASA').”
- “A dividend of £21.22M has been distributed for the year ended 3 January 2025 (Year ended 29 December 2023: £4.5M)”
- “Inflation continued to place economic uncertainty on the company during 2024.”
- “Global supply chain shortages are improving but have continued to place pressure on the business throughout 2024.”

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.
