1. Telent

Size: £460.7m revenue
Acquirer: M Group
When: April
Rationale
Telent CEO Jo Gretton hailed its sale to larger peer M Group as an “exciting new chapter” for the critical national infrastructure tech provider.
Although it ranked tenth in Oxygen 250 2025, in truth Telent really only has half a foot in the IT VAR and MSP world (having acquired HPE partner Richardson Eyres in 2016). It’s better known for providing mission critical communications and network infrastructure to critical infrastructure organisations.
A Sky News report ahead of the deal put the deal size at about £270m.
The acquisition – which is subject to regulatory approval – will boost M Group’s pro forma revenue to over £3bn.
What they said
“Joining M Group marks an exciting new chapter for Telent, reinforcing our leading position in network and technology solutions,” – Telent CEO Jo Gretton
