Gail F. Levine

Antitrust & Competition


Gail Levine co-leads the firm’s global Antitrust & Competition practice, which was recently recognized once again as among Global Competition Review’s “Global Elite.” Gail is a trusted advisor to clients with business-critical mergers or acquisitions facing antitrust issues. She helps them assess antitrust risks and formulate strategic plans to move forward with their deals. She also counsels clients on matters that are central to their daily business and provides concise, actionable options to manage antitrust risk. In addition, Gail defends clients in antitrust investigations, shaping strategies to respond to subpoenas, craft a strong narrative, and settle or defend in court.

She joined Mayer Brown from the Federal Trade Commission’s Bureau of Competition, where she served as a deputy director under Chairman Joseph Simons and Acting Chairwoman Rebecca Slaughter.


  • Handling all aspects of antitrust M&A reviews, including analysis that starts before the deal is even signed: evaluating antitrust risks of potential deals, advising senior leadership on antitrust risks and how to mitigate them, counseling on deal sequencing, and more.
  • Counseling clients on antitrust questions critical to their business, including questions about how to minimize the risk that strong business moves today will draw antitrust litigation in the future, how to train workforces to avoid antitrust violations, and more.
  • Defending clients in antitrust and other FTC investigations, including responding to civil investigative demands, building defenses, and advising on negotiating settlements.
  • Advising investors on antitrust issues that can move the market, such as analyzing likelihood of whether the antitrust authorities will challenge a particular deal, whether the courts will agree with the agencies’ positions, and what the market impact of an interim order will be.

While at the FTC:

  • Supervised FTC challenge to a next-generation gene-sequencing firm’s plan to acquire an alleged nascent competitor (Illumina/PacBio).
  • Oversaw FTC’s action against a pharmaceutical firm and its corporate leadership for allegedly using anticompetitive tactics to shield its drug from price competition (FTC v. Vyera).
  • Supervised the FTC’s actions against drug companies that allegedly used an anticompetitive product-hopping scheme to thwart competition with their lucrative opioid replacement therapy drug. The companies paid $60 million to settle the charges, which has been refunded to consumers.
  • Helped establish, and supervised, the FTC’s Technology Enforcement Division, which investigates anticompetitive conduct in digital technology markets.
  • Oversaw the FTC’s successful challenge to Peabody/Arch Coal, a proposed joint venture in the coal industry.
