Jeremy Calsyn’s practice focuses on the full range of antitrust matters, including merger review, criminal and civil government investigations globally, and U.S. litigation, including complex class actions.  Jeremy has represented clients in their most high-profile and sophisticated matters, including mergers and acquisitions requiring regulatory approval in dozens of jurisdictions, numerous global and U.S.-focused cartel investigations, and in litigation in federal and state courts. Recently, he has navigated several automotive parts suppliers through U.S. Department of Justice and worldwide investigations into industry-wide price fixing—described by the DOJ as the largest criminal investigation it has ever undertaken, and played a major role in arguing the defendants’ successful opposition to class certification in the bearings direct purchaser class action.
