Strategic M&A in European Financial Services: Navigating Regulatory Hurdles

The European financial services sector has emerged as a hotbed for cross-border mergers and acquisitions (M&A) in 2024–2025, driven by the need for scale, technological integration, and competitive resilience. However, the path to consolidation is increasingly obstructed by regulatory gatekeeping—a term describing the proactive scrutiny and intervention by regulators to prevent anticompetitive outcomes, protect national interests, and enforce compliance with evolving frameworks. As dealmakers navigate this landscape, understanding the implications of regulatory hurdles is critical to assessing the viability and structure of transactions.

The Regulatory Maze: Legal, Data, and Foreign Investment Challenges

Cross-border M&A in European financial services faces a labyrinth of regulatory challenges. Divergent legal systems across the EU and UK complicate compliance, particularly in sectors like banking, where employee representation bodies (e.g., works councils) can delay integration timelinesCross-Border Regulatory Challenges in M&A - phoenixstrategy.group^[1].

Meanwhile, foreign investment caps—inspired by China's 51% ownership limits in financial services—have raised concerns about non-EU acquirers seeking to dominate European marketsDifferences in European and US Banking Regulator Stances on M&A to Narrow^[3].

The EU's Foreign Subsidies Regulation (FSR), introduced in 2023, has added another layer of complexity. This framework mandates notifications for transactions involving non-EU acquirers and aims to neutralize unfair advantages from state subsidies. By 2024, the European Commission (EC) had already processed over 50 referrals under this regime, signaling its intent to enforce stricter scrutinySuccessful execution of cross-border transactions: managing regulatory deal risk in the EU and UK^[4].

Case Studies: Blocked, Modified, and Delayed Deals

Regulatory gatekeeping has directly influenced high-profile transactions. In September 2023, the EC blocked Booking.com's proposed acquisition of Etravelion, citing a novel “ecosystems” theory of harm that argued the deal would strengthen Booking's dominance in online travel servicesBeyond Borders: A Guide for Navigating the European Regulatory Landscape^[5].

This shift reflects a broader trend of regulators targeting “killer acquisitions,” where dominant firms acquire potential rivals to stifle innovation.

A recent example of political and regulatory entanglement is the hostile takeover bid by BBVA for Spain's Sabadell.
