Global mergers and acquisitions activity has staged a decisive comeback. According to McKinsey, deal volume surged 43% in 2025, reaching 4.2% of GDP — a threshold that signals not a cyclical bounce, but a structural reorientation of corporate finance strategy. For CFOs, General Counsel, and M&A Directors operating in European and cross-border contexts, the implications are both immediate and far-reaching.

A Market Reshaped: Cross-Border Deals, Regulatory Tailwinds, and the PE Downmarket Pivot

Three forces are converging to redefine the M&A landscape heading into 2026. First, cross-regional transactions now account for 19% of total deal value, reflecting a deliberate shift by acquirers toward geographic diversification and access to growth markets — particularly in advanced industries and technology. For European corporates, this represents both an opportunity to expand into North American and Asia-Pacific markets, and an imperative to defend against inbound acquisition interest.

Second, the regulatory environment has materially improved. In the United States, DOJ and FTC merger blocks fell to just three in 2025, compared to an annual average of six — a signal that antitrust scrutiny, while still present, is being applied with greater precision. European dealmakers should note that while the EU’s merger control framework remains rigorous, particularly under the Foreign Subsidies Regulation (FSR), the overall global posture toward consolidation is increasingly permissive. This creates a more predictable environment for structuring cross-border deals and conducting due diligence with greater confidence on timeline certainty.

Third, private equity firms are pivoting downmarket. Faced with challenging exit environments and elevated hold periods driven by dry powder accumulation, PE sponsors are targeting lower middle-market assets — typically companies with EBITDA between €5M and €25M — where competition is less intense and valuation multiples remain more rational. OEP’s acquisition of Wheeler Fleet Solutions and Great Hill Partners’ closure of a $5 billion fund despite 2021-vintage headwinds exemplify this strategic repositioning.

AI-Driven Tech M&A and Sector Concentration in Healthcare

The technology sector continues to generate significant deal momentum, anchored by artificial intelligence capabilities acquisition. IBM’s purchase of AI consultancy Hakkoda is emblematic of a broader pattern: established technology and industrial players are acquiring specialist firms to accelerate digital transformation rather than build organically. For CTOs and corporate development teams, this trend underscores the premium being placed on proprietary data infrastructure, machine learning talent, and sector-specific AI deployment expertise.

In healthcare, buy-and-build strategies are driving strong dealflow across fragmented sub-sectors — from diagnostics to specialty care and medtech distribution. Mid-market healthcare platforms are attracting both strategic acquirers such as Bristol-Myers Squibb and financial sponsors seeking defensible, recurring-revenue assets. Post-merger integration in this sector demands particular attention to regulatory compliance, clinical governance frameworks, and workforce retention — areas where early-stage planning materially affects value realisation.

Implications for European Decision-Makers

For board members and executive teams navigating this environment, several actionable priorities emerge:

  • Reassess cross-border deal readiness. With cross-regional transactions at 19% of deal value and rising, European mid-market companies must ensure their legal, financial, and operational infrastructure can support multi-jurisdictional due diligence processes and post-merger integration across different regulatory regimes.
  • Engage PE sponsors proactively. The downmarket pivot by private equity means that companies previously below the radar of institutional capital are now active targets. Understanding your firm’s attractiveness to financial sponsors — and the implications for governance and exit strategy — is a board-level conversation that cannot be deferred.
  • Prioritise AI and digital assets in portfolio strategy. Whether acquiring or divesting, digital capabilities are increasingly central to valuation. Companies that can articulate a credible AI integration roadmap will command superior multiples and attract a broader buyer universe in competitive processes.
  • Monitor EU regulatory developments in parallel. While US antitrust posture has softened, the European Commission’s FSR and Digital Markets Act continue to introduce complexity for cross-border deals involving digital or strategically sensitive assets. General Counsel must build FSR compliance assessments into deal timelines from the outset.

Key Takeaway

The 2025 M&A surge is not simply a function of lower capital costs or pent-up demand — it reflects a fundamental recalibration of corporate strategy in response to geopolitical stabilisation, technological disruption, and evolving capital allocation priorities. For mid-market executives across Europe, the window to act — whether as acquirer, target, or strategic partner — is open. The firms that will capture disproportionate value are those that combine rigorous due diligence discipline, cross-border execution capability, and a clear-eyed view of how artificial intelligence and regulatory dynamics are reshaping competitive positioning in their sectors.
