North American buyers drive European M&A to a decade-high $117.5 billion in Q1 2026 as the transatlantic valuation gap hits its widest since 2022
PitchBook's Q1 2026 Global M&A Report reveals that North American acquirers deployed approximately $117.5 billion into European targets in the first quarter of 2026 — a pace that, if sustained, would mark the highest annual value of transatlantic acquisitions in a decade. Overall European M&A deal value reached $385.6 billion in Q1, up 5.3% quarter-on-quarter and a striking 42% year-on-year. The primary driver is a widening valuation gap between US and European markets, now at its broadest since 2022. On an enterprise value (EV) to revenue basis — a standard measure comparing a company's total value to its annual sales — US companies trade at 2.1x revenue versus just 1.4x in Europe. This 0.7x differential means US acquirers can buy comparable European businesses at a meaningful discount to what equivalent assets would cost at home, creating structural incentive for cross-border deal activity. The data signals that US corporates and private equity sponsors are treating European market dislocation as a buying opportunity, particularly as geopolitical uncertainty has weighed on European equity valuations. The trend has direct implications for London advisory practices, which sit at the intersection of transatlantic deal flow — English law governs a significant share of cross-border acquisition agreements, and London remains the primary hub for structuring US-into-Europe transactions.
Why this matters
A decade-high pace of US-into-Europe M&A creates sustained demand across multiple practice areas simultaneously: public and private M&A, regulatory clearance (particularly EU Merger Regulation and CMA review for UK targets), leveraged finance, and foreign direct investment screening under national security regimes such as the UK's National Security and Investment Act 2021. The valuation gap story is the 'why now' trigger — European assets look cheap in dollar terms, and US acquirers with dollar-denominated capital are motivated to move. For City firms, this is a direct pipeline driver: cross-border mandates typically require co-ordinated English and target-jurisdiction legal teams, with London offices leading on deal structure and governing law.
On the Ground
On a cross-border acquisition mandate, a trainee would draft and maintain the conditions precedent (CP) checklist tracking all regulatory approvals required before closing, verify disclosure letter entries against due diligence findings, and prepare Companies House filings once the deal completes.

Soundbite
The US–Europe valuation gap is the sharpest deal catalyst City M&A practices have seen since 2022.
Question you might get
“A US acquirer is buying a UK defence-adjacent technology company — what regulatory approvals would you flag, and which might cause the most delay?”
Full answer
PitchBook's Q1 2026 data shows North American buyers deployed $117.5 billion into European targets in a single quarter — a decade-high run rate — driven by a valuation gap where US companies trade at 2.1x EV/revenue versus 1.4x in Europe. For law firms, this translates directly into cross-border M&A mandates requiring English-law deal structures, multi-jurisdictional regulatory clearance, and leveraged finance packages. The trend reflects a structural moment: European equities have been depressed by macro uncertainty, and dollar-funded acquirers are taking advantage. This suggests advisory volumes will remain elevated through H2 2026, with UK and EU regulatory clearance work — particularly NSI Act filings for sensitive sectors — becoming an increasingly contested specialism.
