Antitrust

A&O Shearman’s global antitrust team is a powerhouse that advises corporates, private equity and financial institutions on their most significant transactions, investigations, and litigation. 

Progress-Coral A

The breadth and scale of our U.S., U.K., and EU practice together with our global network and industry knowledge means we are uniquely placed to advise on complex multijurisdictional matters involving parallel proceedings and inter-agency co-operation.  

Extensive experience in FDI screening and merger control 

As one of the premier competition practices in the world we handle the full spectrum of antitrust issues including merger control; cartel and behavioral investigations; dominance and monopolizations; compliance and counseling; and vertical and horizontal agreements. 

We have extensive experience in successfully guiding high-profile transactions through national public interest reviews and managing the interplay between foreign direct investment/national interest screening and merger control regimes. 

We also advise on market investigations and sector-specific regulatory issues; public procurement and competitive tendering; state aid and U.K. subsidy control; and litigation, including antitrust class action lawsuits and complex litigation at the intersection of antitrust and intellectual property law.  

Critical enforcer experience and insight 

Our team includes former regulators who have held leadership positions in, and maintain long-standing relationships with, key enforcement authorities including the U.S. Department of Justice, the Federal Trade Commission, the U.K. Competition and Markets Authority, the European Commission, and China’s SAMR. This gives us real insight into how agencies approach antitrust cases.  

Our team’s experience includes representing clients on some of the world’s most challenging, multijurisdictional antitrust cases that have broken new ground and set legal precedents.  

From litigating cartel cases all the way to the European Court of Justice in Luxembourg to defending merger transactions in jurisdictions around the world, we have the technical skills, industry experience and agency relationships to help our clients achieve their business objectives and address their competition challenges.
