What's in the bulletin?

  • The total estimated value of inward mergers and acquisitions (M&A) saw a notable increase in Quarter 4 (Oct to Dec) 2025, the highest since Quarter 2 (Apr to June) 2021, while the values of domestic and outward M&A decreased.
  • The value of inward M&A (foreign companies acquiring UK companies) during Quarter 4 2025 was £27.4 billion, £19.8 billion more than in Quarter 3 (July to Sept) 2025 (£7.6 billion); this was largely because of an increase in the number of deals over £1 billion.
  • The value of domestic M&A (UK companies acquiring other UK companies) was £1.8 billion during Quarter 4 2025, which was £5.3 billion lower than in Quarter 3 2025 (£7.1 billion).
