UK M&A deals of the week: 19 September 2025

UK M&A deals of the week: 19 September 2025

This week’s UK M&A activity spanned private equity, healthcare, banking, technology, and retail. From Apax Global’s £794 million delisting to Sainsbury’s collapsed Argos sale, the developments show how global capital is reshaping the UK’s investment landscape and pressing established players to adapt their strategies.







This week’s M&A activity reflects both the globalisation of capital and the structural pressures shaping the UK economy. Apax Global’s delisting is part of a wider shift in which private equity sponsors are withdrawing listed investment vehicles from public markets, seeking greater control over asset deployment away from quarterly scrutiny. IG Group’s move into crypto shows how UK financial institutions are pushing for relevance in emerging asset classes, pursuing diversification as retail trading volumes normalise.

Spire Healthcare’s potential sale highlights how infrastructure and private equity investors are positioning to capture long-term demand in healthcare, where demographic pressures and NHS partnerships create a resilient revenue base. At the same time, Investec’s cross-border push into Switzerland illustrates how mid-tier banks are scaling advisory reach to compete with larger global players. The collapse of Sainsbury’s Argos talks, by contrast, underscores the difficulty of finding buyers for legacy retail operations, a reminder that not all restructuring ambitions can be realised through M&A.

Taken together, the week’s deals suggest a bifurcation in the market: international capital is flowing into sectors seen as scalable, durable, or high-growth — such as healthcare, financial services, and digital assets — while traditional consumer businesses face a tougher environment for strategic exits. For executives, the message is clear: dealmaking is alive, but buyers are being highly selective, favouring resilience, global reach, and technological edge.

  • Private equity in retreat from public markets — Apax Global’s delisting shows sponsors continue to pull capital into private vehicles, where they can exert tighter control over strategy and valuation.
  • Healthcare and finance draw global investors — Spire’s £1.4 billion process and IG’s crypto acquisition highlight where international capital sees scale and structural growth.
  • Retail faces strategic headwinds — The breakdown of Sainsbury’s Argos talks demonstrates how legacy retail assets struggle to attract buyers, even amid wider dealmaking momentum.
