Mergers

What’s changing, and why is it important?

In July 2026, the Ministry of Economy & Tourism of the United Arab Emirates (the “Ministry” and “UAE”) published its Guidelines on Relevant Market Definition (the “Guidelines”), providing a detailed look into the Ministry’s framework for market definition assessment. The Ministry considers market definition to be a “fundamental pillar” to the competitive assessment across all competition enforcement contexts and a “crucial stage” in competition enforcement.

The issuance of the Guidelines marks a further important step in the implementation of the UAE’s competition law regime. It follows the introduction of revised merger control thresholds in 2025 and the adoption in April 2026 of implementing regulations for the 2023 Federal Competition Law (see our previous blog on these reforms).

The Guidelines are particularly important for the UAE’s merger control regime, where filing obligations are dependent on parties meeting revenue and/or market share thresholds in the “relevant market” in the UAE. The introduction of the Guidelines provides a crucial tool to merging parties and advisers for determining when transactions may require mandatory notification to the Ministry. More substantively, the Guidelines will provide an important source to help merging parties prepare the “economic report” on the competitive effects of a merger required by the UAE merger notification rules. Beyond merger control, the Guidelines will also provide an important tool for self-assessment of behavioural competition law compliance.

On 30 April, the UAE adopted Cabinet Decision No. (59) of 2026 (“the 2026 Executive Regulations”), setting out the executive regulations for Federal Decree-Law No. (36) of 2023 on the Regulation of Competition. The 2026 Executive Regulations replace the previous implementing regulations adopted in 2014 under the former UAE competition law. They are expected to enter into force on 30 July 2026.

Taken together, the adoption of Federal Decree-Law 36 on Regulating Competition of 2023, Cabinet Resolution No. (3) of 2025 establishing the new filing thresholds, and the subsequent adoption of the 2026 Executive Regulations complete a long-anticipated overhaul of the UAE merger control framework. These measures mark a decisive shift towards a fully operational and modern merger control regime. The 2026 Executive Regulations significantly streamline the notification process, introduce enhanced timing certainty, and create a clear pathway for third parties to engage with the Competition Department of the Ministry of Economy & Tourism (“Competition Department”) to influence the outcome of merger reviews.

More broadly, the 2026 Executive Regulations introduce important changes to various aspects of UAE’s competition law framework, including measures relating to behavioural competition enforcement and procedures. In combination with other recent competition policy and enforcement actions, the 2026 Executive Regulations signal the UAE’s ambition to bring its competition and merger control framework in line with international best practice.

This article focuses on the main revisions to the UAE merger control framework, before briefly outlining the wider changes introduced to the UAE’s behavioural competition regime by the 2026 Executive Regulations.

Introduction

On Thursday 8 May 2025, the EU took another important step towards revamping its framework to screen foreign investment, with the European Parliament adopting an amended version of the bill (the “EP Bill”, available here). That vote has now cleared the way for the next step in the legislative process: the tri-partite negotiations between the European Commission, the Council of the EU, and the European Parliament (aka “trilogue”) to arrive to a final text that will become law.

The EP Bill endorses the Commission proposal[1] that sought to bring more harmonisation/oversight over Member States, but also goes further and makes several ambitious additions to the Commission proposal in particular, the EP Bill would: (i) give new decision-making powers to the Commission in an area where such powers previously have squarely rested in the hands of the EU Member States, (ii) expand the list and scope of sectors in which foreign investments could undergo screening, and (iii) require reporting and screening of greenfield investments above a certain amount in many sectors.

This post explains these key proposed changes for non-EU investors and sets out how we see the prospects of these changes surviving the remainder of the legislative process.

Significant changes to the U.S. merger notification regime under the Hart-Scott-Rodino (“HSR”) Act are currently anticipated to go into effect on February 10, 2025, based on an update to the Federal Register publication schedule.

The Federal Trade Commission (“FTC”) announced the Final Rule implementing the changes to the HSR notification form on October 10, 2024…

On October 10, 2024, the federal antitrust agencies finalized the most significant changes to the U.S. merger notification regime since the enactment of the Hart-Scott-Rodino (“HSR”) Act in 1976. The Final Rule—which was issued by the U.S. Federal Trade Commission (“FTC”) with the concurrence of the Antitrust Division of the Department of Justice (“DOJ”) (together, “the Agencies”)—will significantly increase the burden on companies whose transactions must be notified to the Agencies pursuant to the HSR Act.

On 3 September 2024, the European Court of Justice (“ECJ”) published its highly-anticipated judgment in Illumina/Grail v Commission (Joined Cases C‑611/22 P and C‑625/22 P) (“ECJ Judgment”), regarding the scope of application of Article 22 of the EU Merger Regulation (“EUMR”).

The ECJ set aside the EU General Court (“GC”) judgment (Case T‑227/21) and ruled that the European Commission (“Commission”) does not have jurisdiction over transactions referred to it by the national competition authorities of EU Member States (“NCAs”) if the transactions do not meet the national thresholds of the referring EU Member States.

Key takeaways

  • Based on a historical, contextual, and teleological interpretation of Article 22 EUMR and the EUMR itself, NCAs cannot ask the Commission to examine transactions which do not meet their national thresholds.
  • Article 22 EUMR provides for a corrective function regarding the allocation of competences between the Commission and NCAs, and is to limit the possibility of multiple parallel notifications, providing legal certainty and facilitating the one-stop shop principle.
  • An amendment of the EUMR thresholds and/or referral rules to capture below-threshold transactions would likely entail a burdensome legislative process and complex negotiations with EU Member States.
  • The Commission can still rely on (i) new thresholds which have by now been introduced in some EU Member States to catch transactions outside the scope of their traditional turnover-based thresholds, and (ii) the possibility for NCAs to review these transactions by means of Article 102 TFEU, which prohibits abuses of a dominant position.

On 18 July 2024, the current President of the European Commission (“Commission”), Ursula von der Leyen, was reconfirmed by the European Parliament for a second 5-year term. As part of her reconfirmation, President von der Leyen delivered a speech before the European Parliament, complemented by a 30-page program, which lays down the Commission’s political program for the next five years.

A key pillar of the program – “A new plan for Europe’s sustainable prosperity and competitiveness” – has the objective of combining competitiveness and prosperity with the achievement of the European Green Deal goals.

Specifically on competition policy, according to President von der Leyen, a new approach is needed to achieve this objective. This blog post projects where competition policy is likely headed in the 2024-2029 period by commenting on the most relevant paragraphs of the program.

Last summer, the antitrust agencies proposed sweeping changes to the Hart-Scott-Rodino (“HSR”) Act premerger notification form and associated rules. Covered in detail here, the proposed changes would significantly increase the time, burden, and costs on merging parties to prepare an HSR filing. The public comment period ended on September 27, 2023. Since then, the agencies have given little indication what changes would be made in response to the comments or when the proposed rules would be finalized.
