Criminal Antitrust and Cartel Investigations

Strategic Defense for High-Stakes Antitrust Cartel Cases

Sheppard's criminal antitrust and cartel team defends companies and executives against high-stakes government antitrust enforcement actions. 

Our former senior prosecutors from DOJ, FTC, DG Comp and U.S. Attorneys’ offices bring key insight to antitrust investigations

Rapid Response Advocacy for Businesses and Individuals 

We defend clients in the most complex, high-stakes cartel matters, where the risks include criminal charges, incarceration and enterprise-threatening fines.

Whether representing an individual under indictment, a company swept into a global investigation, or guiding multinationals through simultaneous civil and criminal proceedings, Sheppard brings the experience, agility and advocacy to protect our clients’ highest interests. 

Criminal antitrust investigations often begin with sudden, high-profile government actions—search warrants, subpoenas, dawn raids or coordinated multi-agency inquiries. We act swiftly in those critical first hours, managing crisis response, coordinating across jurisdictions, and protecting both personal and corporate interests. Our work spans all major criminal cartel allegations, including price-fixing, bid-rigging, no-poach and wage-fixing, algorithmic collusion, information sharing and market allocation.
