Hill Wellford

Hill Wellford heads the firm’s Antitrust Government Investigations team and is co-head of its HSR group. Since leaving the DOJ Antitrust Division for private practice, he has focused on matters in the energy, technology, pharmaceutical and media industries, both in the U.S. and internationally. Chambers USA calls him “very strong” in antitrust and “one to watch” (2019).

Hill’s antitrust practice includes matters in the Americas, Asia and Europe. He files dozens of “merger control” notifications yearly under the U.S. Hart-Scott-Rodino Act (HSR Act) and parallel international laws, and his non-deal work includes cartel and criminal investigations, civil conduct challenges, and jury, bench, and administrative trials. He also counsels third parties involved in merger divestitures and has been appointed by the U.S. Federal Trade Commission (FTC) as counsel for agency-installed divestiture monitors and trustees.

Hill also works with the Committee on Foreign Investment in the United States (CFIUS). He assesses the deal risks of a national security review and makes voluntary and mandatory CFIUS filings, in compliance with the 2018 Foreign Investment Risk Review Modernization Act (FIRRMA) and the 2020 Treasury Department final CFIUS rules on “critical technologies” and other subjects.

Hill is a longtime leader in the American Bar Association’s Section of Antitrust, where he is a member of the International Developments and Comments Task Force (IDCTF), co-chaired the Dominance Divergence Task Force that issued a landmark 2019 report, and served a three-year term on the section’s governing Council. His government service included several positions in the U.S. Department of Justice (DOJ) Antitrust Division in Washington, DC, including Chief of Staff, trial attorney, investigator and Legal Policy counsel. He obtained the highest security clearances for classified information and restricted data (nuclear weapons and energy), including TS/RD. At DOJ, he also worked with the OECD, ICN, and foreign agencies, particularly focused on Asia, on matters of international trade.
