Market trends

Prospectus reform: a procedural tailwind for listed acquirers

Quietly, the structural change that might have the biggest impact on UK M&A in 2026 is procedural. 

Under the new prospectus regime, listed companies can issue shares up to 66.6% of their existing capital without shareholder approval and up to 75% without a full prospectus

For dealmakers, this removes a long-standing disadvantage for London-listed acquirers, who previously faced circular requirements and approval timelines that continental and US rivals did not. 

The direction of travel matters: 

  • Mega deals above £1bn rose to 34 in 2025, up from 31 in 2024, even as overall deal volume fell 13%;
  • PE bidders featured in 44% of public M&A versus 31% the prior year, and US buyers alone accounted for aggregate deal value exceeding the entirety of domestic UK M&A.

According to UK Finance data, geoeconomic confrontation now sits at the top of the near-term risk rankings, rated close to 5 out of 7 in severity and having jumped from ninth place the prior year. 

  • The WEF frames the risk as broader than tariffs: it encompasses institutional erosion, the use of sanctions to protect strategic capabilities, and fewer constraints on unilateral action by major powers.

The ten-year picture shifts materially on AI. Near-term severity sits below 3.5, placing it 30th in the immediate rankings. 

Over a decade, that figure climbs above 5, the sharpest horizon gap of any risk category. The problems that arise are rooted in gaps in governance, unequal benefit distribution, and labour displacement.

UK & Ireland mid-market: fewer transactions, higher aggregate value

UK and Ireland mid-market M&A closed 2025 with 739 transactions, down 12% on the prior year, yet aggregate deal value climbed 7% to $68bn. 

The post-COVID boom of $72bn in 2022 came on the back of a crowded market; last year’s figure arrived through discipline, with bidders cutting noise and targeting fit.

  • TMT held the top position at 213 deals
  • But TMTs 22% forward pipeline share is now being stalked by Business Services at 21%, up from 84 to 99 transactions across the year. 

The assets drawing the sharpest competition sit at the intersection of both: SaaS platforms, cybersecurity, AI infrastructure. In that context, some deals stood out:

  • NVIDIA paid $500m for autonomous vehicle software developer Wayve Technologies. 
  • Wolters Kluwer paid the same for Irish legal-tech firm Brightflag.
