Steve Cernak is a senior antitrust and competition law partner at Bona Law with deep experience advising Fortune 500 companies, emerging businesses, and clients across industries on the full spectrum of antitrust risk. He is a former Chair of the ABA Antitrust Law Section and has been recognized by Best Lawyers© in antitrust law every year since 2020.

What sets Steve apart for sophisticated clients is his more than 20 years as in-house antitrust counsel at General Motors, where he ultimately led the company's antitrust function — covering merger review and HSR filings, antitrust litigation, and global antitrust compliance programs. That in-house background means Steve understands how legal risk lands inside a large organization, how to communicate antitrust issues clearly to business leaders and boards, and how to build practical solutions rather than just identify problems.

Steve advises clients on:

  • Merger review and HSR filings — including second requests and international filings
  • Global antitrust compliance programs — design, implementation, and training
  • Pricing strategies and distribution arrangements — including resale price maintenance, most-favored-nation clauses, price discrimination, and vertical restraints
  • Joint ventures and competitor collaborations — structuring and managing arrangements to minimize antitrust exposure
  • Antitrust litigation and government investigations — including DOJ and FTC matters

After GM, Steve spent seven years at Schiff Hardin (now Arent Fox Schiff) before joining Bona Law, serving clients in automotive, manufacturing, technology, franchising, and distribution industries. He is based in the Detroit area.

Steve is also one of the most published antitrust lawyers in the country. He is the author of Antitrust Simulations (West Academic, 3rd ed.) and Antitrust in Distribution and Franchising (LexisNexis, updated annually), and has taught antitrust law at the University of Michigan Law School and the Thomas M. Cooley Law School Corporate & Finance LLM program. He is a frequent commentator on antitrust developments across legal, business, and mainstream media.
