UK M&A deals of the week: 25 October 2025

This week’s M&A activity spanned consumer wellness, technology infrastructure, managed services, market infrastructure, and financial markets. From Supreme’s expansion into diet brands to the London Stock Exchange Group’s strategic restructuring, UK companies focused on repositioning for scale, efficiency, and capability rather than outright size.







This week’s M&A activity underscored the deliberate, strategic tone defining the UK deal landscape. Rather than headline-grabbing takeovers, the market is being reshaped by targeted acquisitions, mergers, and asset sales designed to strengthen balance sheets and reposition businesses for future growth. Consumer goods companies are pursuing brand rejuvenation; financial and infrastructure players are rationalising holdings and expanding specialist capabilities; and technology-service providers are consolidating to build national scale.

In aggregate, these transactions illustrate an M&A market characterised by precision rather than volume — deals rooted in focus, capability, and partnership. With capital markets still cautious, UK companies appear to be writing a new playbook: using smaller, purposeful deals to achieve strategic transformation, often with global reach but local execution.

  • Strategic repositioning dominates — UK companies are reshaping portfolios and capabilities through focused acquisitions, disposals, and mergers rather than large-scale takeovers.
  • Mid-market momentum — Activity is strongest among mid-cap and private-equity-backed players, where agility and sector focus allow meaningful strategic moves despite market uncertainty.
  • Global reach, domestic base — Whether expanding abroad or inviting international capital in, UK enterprises continue to operate as outward-facing hubs in global M&A activity.
