Merger Control

Successfully steering transactions through competition and regulatory review worldwide


Merger control regimes have multiplied across the globe, with effective merger control strategy and its execution key to the timing and success of many deals.

We partner with clients to identify antitrust risks and formulate a filing strategy at the outset, advising on optimum transaction structure, competition due diligence and guiding a transaction through competition and regulatory review to completion.

Our global team regularly advises on all aspects of securing clearances from antitrust regulators worldwide, where necessary developing, negotiating and implementing complex remedy packages. In cross-border transactions we coordinate multijurisdictional filings globally, ensuring a consistent and coherent approach.

We have significant expertise in handling in-depth reviews and in obtaining clearances based on innovative commitments, together with extensive experience dealing with the particular challenges of managing merger reviews in nascent competition regimes. Our thorough sector knowledge means we are well-placed to advise on a broad range of issues, including dealing with the interplay between competition and regulatory requirements in markets such as transport, infrastructure, water, telecommunications and energy.

Our team also has a significant track record in contentious merger control matters, both in appealing merger control decisions on behalf of both merging and third parties, and acting for clients seeking to challenge a merger of their competitors, customers or suppliers through the regulatory process.

Our EU law experts have unparalleled expertise in merger control matters, obtaining clearances from the European Commission for international deals in the most efficient manner possible. The team has an excellent understanding of the workings of the EU, drawing on the experience of former secondees, officials and judges at the European Commission and EU courts.
