Hello,

We’ve reached December, it’s all downhill from here. And yet there’s still deals being done, such as CVC’s £2bn acquisition of Smiths’ airport scanner unit.

There’s also plenty in the rumour mill, such as:

  • Blackstone is making plans to sell a Canary Wharf office block
  • BHP offered £40bn in its attempt to buy Anglo American
  • Airport handler Menzies is considering an IPO

Market trends

Megadeals dominate the market

The Office for National Statistics reveals a notable contrast in Q3 2025: while UK M&A values held remarkably steady, the number of domestic deals plummeted to just 158 transactions, the lowest level since 2017. 

This disparity, with domestic M&A values actually rising to £5.3bn (up £1.9bn from Q2) despite 89 fewer deals, signals a market increasingly concentrated in mega-transactions rather than broad-based activity.

Public offers tick along in October

Turning the page to Q4, October’s public M&A landscape maintained a stable rhythm with three firm offers announced, marking activity levels broadly consistent with the same period in 2024. 

What stands out is the continued dominance of strategic buyers, which drove two of the three firm offers during the month, extending a trend that has defined the second half of 2025 and represents a marked shift from the sponsor-heavy environment of October 2024. 

Noteworthy transactions included Cicor Technologies’ £287m approach for TT Electronics and Long Path’s £339.5m public-to-private take of Idox, while the computer and electronic equipment sector emerged as the month’s hotspot with three separate approaches.

BDO tops Q3 advisory charts

And finally, congratulations to BDO for securing first place in PitchBook’s Q3 2025 Global League Tables as the most active advisor in UK and Ireland M&A, leading the field with 35 deals.
