Tracy (Januzzi) Penfield understands how important your deal is to you and how critical it is to chart a quick and efficient path to regulatory clearance that aligns with your deal timeline.

She focuses on guiding clients through the premerger notification process under the Hart-Scott-Rodino Antitrust Improvements Act and has significant experience with mergers and acquisitions involving multi-jurisdictional investigations and second request reviews. Tracy's clients rely on her practical advice and solutions during the merger review and clearance process to minimize their regulatory burden.

Tracy advises on transactions in an array of industries, including defense; energy and natural resources; consumer; financial institutions; and technology, media, and telecommunications.

Tracy is also known for her problem-solving ability and industry know-how outside the merger realm. She regularly counsels clients on a wide range of general antitrust compliance issues and often serves in a general counsel role at trade association meetings, providing practical advice to enable companies to operate profitably and effectively within the confines of the antitrust laws.

Before joining the firm, Tracy served as a judicial law clerk to the Honorable Christine Odell Cook Miller of the U.S. Court of Federal Claims and the Honorable Marcus D. Williams of the Fairfax County Circuit Court. While in law school, she was the managing editor of the Catholic University Law Review.
