The EU Is Rewriting Its Merger Rulebook to Build Corporate Giants

For decades, the European Commission's approach to mergers was built on a single animating principle: protect the consumer from concentrated market power. Price, choice, and competition were the metrics that mattered. Now, Brussels is quietly but deliberately shifting that calculus, signaling that scale, investment capacity, and geopolitical weight deserve a seat at the table too.

Draft reforms to the EU's competition framework would instruct regulators to give greater weight to the benefits of size when assessing proposed mergers and acquisitions. The goal, as framed by European officials, is to cultivate so-called "European champions" — large, well-capitalized companies capable of competing with American tech giants and Chinese state-backed conglomerates on the global stage. It is a vision that would have been considered heretical in Brussels just ten years ago.

The timing is not accidental. Europe has watched with mounting anxiety as its corporate landscape has failed to produce the kind of transformative, globally dominant firms that have emerged in the United States and China. The continent that gave the world Airbus and ASML has struggled to birth a homegrown tech titan, a dominant cloud provider, or a battery manufacturer capable of challenging CATL. Meanwhile, the Draghi report on European competitiveness, published in late 2024, delivered a blunt diagnosis: Europe is falling behind, and fragmented markets are part of the reason.

The argument for relaxing merger rules flows directly from that anxiety. If European firms are too small to invest at the scale required for AI infrastructure, green energy transition, or semiconductor fabrication, then blocking consolidation in the name of domestic competition may be self-defeating. A market with three mid-sized telecom operators competing on price might look healthy by traditional metrics while remaining structurally incapable of funding the next generation of network infrastructure.

This is the tension at the heart of the reform: short-term consumer welfare versus long-term industrial capacity. And it is a tension that orthodox competition economics has never fully resolved.

The risks of this reorientation are real and worth taking seriously. Europe's competition authority, DG COMP, built its global reputation precisely because it was willing to block or condition mergers that other regulators waved through. That credibility attracted investment and signaled rule-of-law reliability. Softening the framework, even at the margins, introduces a new variable: political judgment about which industries matter and which companies deserve to win.

History offers cautionary tales. Japan's industrial policy of the 1980s and 1990s produced some globally competitive firms, but also entrenched inefficiencies and zombie companies propped up by coordinated protection. South Korea's chaebol model generated Samsung and Hyundai, but also systemic governance problems and suppressed domestic competition that hurt Korean consumers for generations. The "national champion" concept has a mixed record at best.

There is also a second-order effect worth watching closely. If the EU signals that size and investment capacity can offset competitive harm in merger reviews, it will change the behavior of deal-makers long before any specific merger is filed. Companies will structure acquisitions differently, frame synergy arguments in terms of R&D investment and global competitiveness, and lobby harder for industrial policy carve-outs. The reform, in other words, will reshape the incentive landscape across European boardrooms well before it reshapes any specific market.

Smaller firms and startups face a subtler threat. One of the underappreciated functions of strict merger control is that it preserves the credible independence of smaller competitors, making it harder for dominant players to simply acquire their way out of disruption. If that discipline weakens, the acquisition premium for European startups may rise in the short term, but the long-term pipeline of independent challengers could thin out.

The European Commission is betting that the geopolitical moment justifies the trade-off. That may prove correct. But the history of competition policy suggests that once regulators begin weighing industrial ambition alongside market structure, the boundary between principled analysis and political convenience becomes very hard to hold. The real test will not be the first high-profile merger approved under the new framework. It will be the tenth.
