The announcement that ON Semiconductor will acquire Synaptics in a $7 billion all-stock transaction is more than a chip-sector headline. It is a signal that strategic buyers, private equity sponsors, and boards across sectors are re-engaging with large, complex cross-border deals despite a mixed macro backdrop. Combined with EDF’s carve-out sale of its U.S. and Canadian power solutions business to KKR, Safran’s exclusive negotiations to acquire French defence-technology group Exail Technologies, and reported sponsor interest from EQT, Advent, and KKR in diagnostics firm Qiagen, current deal flow suggests 2026 could approach Morgan Stanley’s projected $6.4 trillion in global mergers and acquisitions activity. For CFOs, General Counsel, and M&A directors, the question is no longer whether to transact, but how to structure, diligence, and integrate deals that increasingly span sectors, borders, and regulatory regimes.

Strategic Buyers Return to Large-Scale, Cross-Sector Consolidation

Onsemi’s acquisition of Synaptics — its largest transaction to date — reflects a deliberate strategy to expand into AI-enabled devices and physical AI applications, areas where semiconductor and human-interface technologies converge. The all-stock structure is notable: it preserves balance-sheet flexibility while signaling confidence in forward valuations, a pattern likely to recur as strategic acquirers pursue capability-driven mergers and acquisitions rather than pure scale plays. Similarly, Safran’s move on Exail Technologies illustrates consolidation in dual-use maritime and defence technologies, a sector where European industrial policy, export controls, and NATO-aligned procurement increasingly shape deal feasibility.

For boards evaluating similar transactions, three factors are now decisive: technology complementarity, regulatory clearance timelines, and the credibility of integration planning presented to shareholders at signing. Deals structured around AI, defence, and specialty semiconductors face heightened scrutiny from competition authorities and, in cross-border contexts, from foreign investment screening regimes such as the EU’s FDI Regulation and CFIUS in the United States.

Private Equity’s Continued Role in Energy Transition and Healthcare

The EDF-KKR transaction and the reported Qiagen process underscore that private equity remains a structurally important buyer class, particularly for energy-transition infrastructure and life-sciences assets requiring specialized capital and long investment horizons. EDF’s decision to divest its U.S. and Canadian power solutions business to KKR reflects a broader trend of European utilities and industrials monetizing non-core, capital-intensive assets to sponsors better positioned to fund growth outside strategic balance sheets.

For sponsors, the diligence bar has risen. Cross-border carve-outs require rigorous separation planning, transitional service agreements, and clarity on stranded-cost allocation — all areas where deal teams historically underestimate execution risk. The involvement of EQT, Advent, and KKR in the same target class (diagnostics) also signals that competitive sponsor processes are back, compressing timelines and requiring sell-side readiness well before formal marketing begins.

Implications for Corporate Finance and Deal Execution

Three implications stand out for decision-makers structuring or responding to 2026-era deal activity:

  • Due diligence must expand beyond financials. Technology integration risk, IP ownership, export-control exposure, and AI-related data governance are now central to valuation, not ancillary workstreams.
  • Post-merger integration planning should begin pre-signing. All-stock and cross-border deals amplify integration risk; boards should require a credible 100-day plan before approving transaction terms, not after closing.
  • Regulatory strategy is now a deal-timing variable. With FDI screening, antitrust review, and sector-specific export controls converging, General Counsel must map jurisdictional clearance paths at the term-sheet stage, not during signing-to-closing.

Mid-market companies operating adjacent to AI, defence, or specialty hardware ecosystems should treat this consolidation wave as a signal to assess strategic positioning now — either as acquisition targets, platform consolidators, or partners to larger strategics seeking capability tuck-ins.

Key Takeaway

The Onsemi-Synaptics transaction, alongside EDF-KKR, Safran-Exail, and sponsor interest in Qiagen, confirms that large-scale corporate finance activity is recovering across strategic and financial buyer categories. For CFOs, General Counsel, and M&A directors, the priority is building diligence and integration frameworks robust enough for a market where cross-border, cross-sector deals — not domestic scale mergers — define the next 12 to 18 months of dealmaking.
