Fielding a deep bench of former enforcement attorneys, prosecutors, and trial lawyers from the FTC and DOJ, Simpson Thacher & Bartlett LLP‘s antitrust and trade regulation practice is equipped to support clients from industries such as software, transportation, defense, insurance, and advises on the full spectrum of cartel matters, including internal investigations, leniency programs, criminal and regulatory investigations and advice on dawn raids. Covering allegations of price fixing, market allocation, bid rigging, and no-poach, conduct among others, the team is jointly headed by Peter Guryan in New York, John Terzaken, and Sara Razi. Engaged by clients from all major industries, Terzaken handles antitrust enforcement matters as part of his diverse white-collar practice, while Abram Ellis is a name to note for cartel-related civil litigation. Representing multinational corporations, independent board committees, and senior executives in investigations by federal and state enforcement regulators is a key area of work for Jeffrey Knox.
