Courtney Dyer’s practice focuses on government merger and non-merger investigations, private antitrust litigation, and counseling clients on antitrust issues. Courtney has extensive experience defending proposed and consummated mergers and acquisitions before the US antitrust agencies. In recent years, Courtney has represented clients in transactions in the technology, biotech, healthcare, airline, retail sales, manufacturing, telecommunications, automotive, and energy industries.

She also 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 other competition issues. 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.
