European M&A dealmaking stumbled in the first half of 2026, with volumes down 11% relative to H1 2025 despite aggregate transaction value rising 3.6% year-on-year. Sifted tracked 324 exits across Europe, down from 360 in H1 2025. Deal transparency remained poor: only 30 deals disclosed pricing out of 324, reflecting the dominance of early-stage startup exits with undisclosed terms. The largest disclosed European M&A transactions of H1 were Dream Games' €1.1 billion buyout by CVC Capital Partners, Oxford Ionics' €968 million acquisition by US quantum company IonQ, and TTTech Auto's €568 million purchase by chipmaker NXP Semiconductors.
The composition of exits highlights structural weakening: 83% of exits (270 deals) involved early-stage startups, just 9% at growth stage, and 7.9% at late stage. UK dominated with 112 exits, followed by France (68), Germany (58), Spain (28), and the Netherlands (27). Repeat acquirer concentration was low: only 13 buyers closed multiple deals, with most doing just two. Norwegian software giant Visma led with 7 acquisitions, underscoring the shift toward strategic consolidation over financial engineering.
For architects: European M&A volume weakness amid macro uncertainty and financing constraints signals cautious capital allocation. The shift from mid-market buyouts to early-stage fluff or mega-strategic deals (like the Oxford Ionics quantum play) suggests capital is bifurcating between proven, defensible tech assets and structured exits for struggling founders.
