The deadline for the completion of a £1.1bn takeover at listed UK tech firm Spirent has been extended.

Spirent’s acquisition by California-based Keysight Technologies, Inc – agreed in March – was given the green light by the Competition and Markets Authority in April.

The Long Stop Date has been extended from 29th September 2025 to 27th October 2025.

The parties have not yet received a decision from the State Administration for Market Regulation of the People’s Republic of China to conditionally clear the acquisition. It is expected that this will be received shortly.
