Cross-Border M&A in 2026: Navigating Regulatory Complexity

The regulatory environment for transatlantic mergers and acquisitions has shifted dramatically over the past two years. New antitrust frameworks in the EU, evolving CFIUS review processes in the US, and increased scrutiny of technology transfers between jurisdictions have created a more complex landscape for cross-border deal-making.

Key Regulatory Shifts

The European Commission’s expanded merger review thresholds, combined with the Digital Markets Act’s implications for technology-sector acquisitions, mean that deals which would have sailed through review five years ago now face extended timelines and additional conditions. In the US, the expanded scope of foreign investment review under the updated CFIUS regulations has introduced new uncertainty for European acquirers of US technology assets.

Strategic Implications for Acquirers

For organizations pursuing cross-border growth through M&A, three strategic adjustments are essential. First, regulatory risk assessment must move upstream in the deal process — ideally into the target screening phase. Second, deal structures must be designed with regulatory flexibility, including clear remedies and behavioral commitments. Third, integration planning must account for jurisdiction-specific compliance requirements from day one.

The firms that will execute successfully in this environment are those that treat regulatory strategy as a core competency, not a last-mile compliance exercise.
