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

Significant events
- “Announcement on 28 March 2024 that Spirent would be sold to Keysight Technologies, Inc. ('Keysight'). Shareholders approved the Keysight offer on 22 May 2024. The macroeconomic environment in 2024 continued to present headwinds, particularly in the telecom sector, with ongoing budget pressures and a cautious capital expenditure environment. Robust pricing, supply chain management and product mix led to strong gross margin.”
- “Adjusted operating profit increased by 18.2% to $46.2 million in 2024 (2023 $45.2 million).”
- “Net profit (profit for the year) was $44.5 million in 2024 (2023 $44.3 million).”
