Antitrust/Competition Merger Review
We get deals cleared. Our deep understanding of competition authorities gives us the insight, experience, and credibility to secure cost-effective worldwide approval of complex transactions. We rely on frequent dealings with the regulatory agencies, and our team includes former senior government antitrust enforcers. Because of our track record, clients retain us to lead antitrust clearance, even when they use other firms as corporate counsel.
-
Global Reach and Coordination: Our extensive bench of competition attorneys practice before the U.S., EU, and UK competition authorities. We also regularly act as global coordinator of merger and foreign direct investment (FDI) review. We draw on a network of leading independent antitrust and FDI specialists across over 45 jurisdictions, enabling us to provide a “one-stop shop” experience for our clients.

Deep Understanding of Global Competition Authorities: Our antitrust attorneys have held significant senior leadership positions in the Federal Trade Commission, Department of Justice, and the European Commission.

A Team Built to Handle the Toughest Transactions: Our team has been entrusted with our clients’ most challenging mergers — 24 transactions valued at more than US$1 billion and 21 in-depth merger investigations in the last three years alone.
