Where We Excel


Vinson & Elkins’ Antitrust lawyers possess a wealth of experience in the approaches, arguments, and economics necessary to see a transaction through to approval by U.S. and non-U.S. regulatory agencies, including the Federal Trade Commission (FTC), the Antitrust Division of the United States Department of Justice (DOJ), State Attorneys General (AG), the European Commission (EC), and competition in authorities in countries around the world.

Our lawyers are proactive and strategic in helping clients across a variety of industries secure approvals for complex mergers, acquisitions, and joint ventures. We work with clients through the entire clearance process, including assessing risk, advising on transaction structure, conducting due diligence, negotiating agreements, as well as advising on information exchanges, pre-merger coordination, and “gun-jumping.”

Each year, V&E lawyers analyze hundreds of transactions for our clients, and represent them from initial Hart-Scott-Rodino (HSR) or competition notifications, through any competition investigations to final approval, to get deals through. Our regular experience before the various antitrust agencies, and the good working relationships we have developed, provide our clients with valuable insights and efficiencies.
