Historically, the European Union’s (EU’s) merger control framework has provided businesses with a relatively predictable basis on which to assess transaction risk. While enforcement has naturally evolved over time through case law and changing market conditions, the underlying principles governing how the European Commission (EC) evaluates mergers have remained largely unchanged.

That position is now beginning to shift. Earlier this year, the EC published draft revised Merger Guidelines, representing the most significant reform of EU merger control in more than two decades.

The publication of the draft guidelines is significant because it responds to a substantially changed economic and geopolitical environment, one defined by instability, the rise of digital platforms and artificial intelligence (AI), and a renewed focus on European industrial competitiveness.

The proposals will replace the 2004 Horizontal Merger Guidelines and the 2008 Non-Horizontal Merger Guidelines. Although they remain subject to consultation and formal adoption, the draft guidelines are expected to shape the EC’s approach to dealmaking for the foreseeable future.

Competition policy in transition

The draft guidelines seek to adapt EU merger control to a dramatically changed economic and geopolitical landscape. The modern global economy is increasingly driven by digital platforms, AI, data, intellectual property (IP) and innovation. Greater emphasis is also being placed on supply chain resilience, economic security and strategic autonomy, all of which have risen rapidly up political and corporate agendas.

These developments have occurred alongside growing regulatory intervention. Governments across the world are increasingly willing to intervene in transactions involving strategically important sectors, most notably those with national security implications, but also those linked to economic resilience and technological leadership. Beyond traditional defence-related assets, scrutiny increasingly extends to areas such as energy, telecommunications, AI, semiconductors, critical infrastructure, life sciences and critical minerals.

Against this backdrop, the EC has sought to modernise its merger control framework while maintaining its core objective of protecting competition across the bloc.

Given the changing nature of the global economy and the growing importance of innovation, technological capability and data, the EC intends to adopt a broader and more forward-looking approach rather than one focused primarily on existing market structures. Regulators will place greater emphasis on how transactions may affect future innovation, emerging technologies and the evolution of competition over time.

This reflects wider concerns that acquisitions involving innovative businesses could undermine future competition. Consequently, merger reviews are likely to involve more detailed analysis of research and development pipelines, IP portfolios, technological capabilities and potential future market entrants. This shift could have significant implications for companies pursuing transactions in fast-moving sectors.

A wider view of harm

One of the most significant features of the revised framework is the EC’s commitment to looking beyond conventional indicators of market power. Merger assessments have traditionally focused on market definition, concentration levels and the likelihood of higher prices, reduced output or diminished consumer choice. However, the EC has long considered factors including innovation, coordinated effects, buyer power, barriers to entry, efficiencies and foreclosure.

The revised guidelines emphasise that competitive harm can also arise through reduced innovation, weaker resilience, diminished labour market competition, the accumulation of data and the growing influence of digital ecosystems. As a result, the reforms adopt a broader view of how competition operates in modern economies, moving beyond a predominantly price-based assessment while retaining the fundamental principles underpinning EU merger control.

Rather than representing a fundamental break with the past, the revised guidelines constitute an evolution of the EC’s established analytical framework, adapting traditional competition principles to the realities of a digital, innovation-driven and geopolitically complex economy.

Innovation competition is a particular area of focus. Regulators are increasingly concerned about acquisitions that eliminate a future competitive threat before it fully emerges, especially where highly innovative smaller companies are acquired by larger incumbents. This issue is particularly relevant in digital markets, biotechnology and AI.

The guidelines distinguish between a merger’s direct and dynamic effects, structure competitive assessment around concepts such as capabilities, and recognise that mergers can be justified where they generate meaningful innovation benefits.

Another notable feature is the creation of the so-called Innovation Shield, which aims to ensure that merger control does not discourage investment in innovative businesses while allowing intervention where acquisitions risk removing important future sources of competition. The shield does not provide a blanket exemption for start-up acquisitions. Rather, it is intended to provide greater certainty for transactions involving small innovative businesses that are unlikely to raise competition concerns, while preserving the EC’s ability to intervene where necessary.

The guidelines are also expected to encourage greater consideration of organic growth, partnerships and other strategic alternatives where regulatory risks are elevated.

Scale versus market competition

The revised guidelines arrive amid a growing political debate over Europe’s global competitiveness. Faced with strong competition from heavily capitalised rivals in the US and Asia, policymakers are seeking ways to strengthen European businesses and improve their ability to compete internationally.

Some argue that Europe should become more willing to permit consolidation in order to create businesses with sufficient scale to compete globally. Historically, however, such consolidation has often been viewed with caution, as competition policy has prioritised maintaining robust competition within the internal market.

Opponents of a more permissive approach argue that weaker merger control can lead to higher prices, reduced innovation and diminished consumer choice, with no guarantee that larger businesses will ultimately become more competitive internationally.

The revised guidelines represent an attempt to strike a balance between these competing objectives. Rather than introducing a wholesale relaxation of merger controls, they seek to incorporate wider economic considerations without abandoning established competition principles.

Since publication of the draft guidelines in April 2026, the consultation process has generated significant debate among businesses, investors and competition law practitioners. Stakeholders have broadly welcomed the EC’s increased focus on innovation, resilience and global competitiveness, although some have expressed concern that the broader analytical framework could introduce greater uncertainty into merger reviews.

The EC has indicated that it will continue engaging with stakeholders throughout 2026, including through dedicated economic studies and workshops on dynamic merger effects, before publishing the final guidelines later in the year.

International investment under review

The revised guidelines are also likely to influence how international investors approach acquisitions involving European businesses. While the EC continues to welcome investment that promotes growth and innovation, the regulatory environment has become significantly more complex.

In today’s global economy, merger control operates alongside foreign direct investment screening regimes, foreign subsidy investigations and sector-specific national security reviews. The result is an increasingly complex web of overlapping regulatory requirements that dealmakers must navigate.

For companies pursuing cross-border transactions, part 3 of the draft guidelines offers several important insights. The guidelines suggest a more structured framework for assessing national objections to intra-EU transactions, potentially increasing the burden on member states seeking to justify interventions.

Protectionist measures may also become more vulnerable to challenge. The guidelines provide a framework against which national interventions can be assessed, potentially making it easier for businesses to challenge measures that appear motivated by economic protectionism rather than legitimate security concerns.

The guidelines also reinforce the EU’s one-stop-shop principle. At a time when geopolitical pressures are encouraging greater national intervention, the EC is reaffirming its central role in preserving the integrity of the internal market.

Anticipating emerging market dynamics

Another important implication of the revised guidelines is the EC’s willingness to assess competition through a longer-term lens.

Traditional merger analysis has focused largely on existing products, identifiable competitors and measurable market shares. Increasingly, however, regulators are asking whether today’s transactions could reshape tomorrow’s competitive landscape.

This is particularly relevant in innovation-driven industries where future market leaders may not yet have established significant commercial positions. AI is perhaps the clearest example. A relatively small AI company may currently generate limited revenue, yet possess technologies capable of transforming entire industries.

The guidelines provide a clearer analytical framework for assessing these types of transactions. This reflects a broader shift toward assessing competition as a dynamic process rather than a static snapshot of current market conditions. In sectors characterised by rapid technological change, regulators are increasingly concerned with preserving future rivalry and innovation incentives, even where immediate competitive effects appear limited at first glance.

Going forward, internal business plans, research strategies, investment roadmaps, technical expertise and future product development are all likely to become more influential during regulatory reviews. Economic modelling may also play a greater role in demonstrating how competition could evolve under different market conditions.

In this evolving environment, companies must be able to explain and substantiate the strategic rationale behind a transaction or risk encountering regulatory difficulties.

Getting ahead of regulation

Although the guidelines have not yet been finalised, the EC has stated that it expects to complete the review process during Q4 2026.

As preparation for major transactions commonly begins nine to 12 months before completion, companies should already be taking steps to prepare for the revised framework.

Whatever form the final guidelines take, boards and investors increasingly recognise that regulatory strategy can no longer be treated as a procedural step that follows negotiations. It has become a strategic consideration capable of influencing valuation, transaction structure, financing arrangements and even decisions about whether to pursue a transaction at all.

Companies should therefore devote greater time and resources to identifying potential competition concerns at an early stage. Target assessments should examine not only existing overlaps and potential synergies, but also innovation capabilities, future market developments and areas where regulators may identify competition concerns.

Early engagement with specialist advisers, economists and technical experts can help identify issues before they become significant obstacles during formal reviews.

Transaction teams must also be prepared for increasingly information-intensive investigations. The EC is likely to seek detailed evidence relating to research programmes, internal strategy documents and product development plans. Preparing this material in advance can improve the efficiency of regulatory engagement and help shorten review timelines.

Merger control’s next chapter

In today’s dealmaking environment, and with the EC expected to finalise the revised guidelines during Q4 2026, businesses should recognise that regulatory uncertainty is likely to become a permanent feature of major transactions.

EU merger control will continue to evolve as markets become increasingly digital, interconnected and innovation-driven. AI, advanced analytics and more sophisticated economic modelling are expected to play a growing role in regulatory assessments, while cooperation between competition authorities, national governments and other regulators is likely to deepen.

In this environment, dealmakers will need to become more adept at anticipating regulatory concerns and addressing them proactively rather than reacting once problems emerge.

Ultimately, the revised merger guidelines are more than a technical update to European competition law. They reflect a broader shift in how regulators assess competition in an economy increasingly shaped by innovation and technology.

As that understanding continues to evolve, successful dealmakers will need to adapt accordingly, embedding regulatory strategy into every stage of transaction planning, and not treating it as an obstacle to overcome after negotiations have begun.
