Courtney Dyer, Managing Partner of O’Melveny’s Washington, DC office, steers companies through increasingly complex government antitrust investigations and helps them navigate an evolving antitrust enforcement landscape.
Courtney has extensive experience defending proposed and consummated mergers and acquisitions before the US antitrust agencies. She is adept at analyzing complex transaction structures and advising clients on appropriately managing antitrust risk before agreements are executed. Focusing on the clients’ strategic objectives and supported by O’Melveny’s global antitrust team, Courtney crafts merger control strategies to achieve these objectives efficiently.
Senior executives at leading companies across a wide variety of industries rely on Courtney for strategic advice on how to achieve their business objectives while managing antitrust risk. In addition to her M&A work, she counsels clients on non-merger matters, including the formation of joint ventures and other competitor collaborations, Section 8 of the Clayton Act, information and data-sharing among companies, and pricing and distribution strategies. Courtney has advocated for government intervention on behalf of parties adversely impacted by proposed mergers, or by anticompetitive conduct.
In addition to her work in government investigations, Courtney devotes a significant portion of her practice to advising clients on issues relating to the Hart-Scott-Rodino Antitrust Improvements Act of 1976 (HSR Act). Her work in this area has also involved negotiating antitrust provisions in transaction agreements, developing client HSR Act training programs and compliance procedures, and representing clients in “failure to file” situations.
