Rebecca Farrington

Partner, Washington, DC



The "extremely pragmatic" Rebecca Farrington "provides good market context and communications in a way that clients can easily navigate." She is nationally ranked as one of 17 "Leading Merger Control Lawyers" by The Legal 500, US (2021 - 2023), and clients describe her as an "absolute star" who is "highly credible," "confident, skillful … and always extremely well organized" with "a lot of experience and judgment" in Chambers USA (2023, 2022). She was named "Retail, Consumer, Food & Beverage Dealmaker of the Year" by The Deal -- Best of the Middle Market Awards (2020) and "Best in Antitrust/Competition" by Euromoney LMG Americas (2019).

Her practice focuses on government merger and non-merger investigations, private antitrust litigation, and counseling on antitrust issues.

Rebecca has developed a significant track record defending proposed and consummated mergers before the Federal Trade Commission and the Department of Justice. Clients she has assisted have operated in a broad spectrum of industries, including pharmaceuticals, healthcare, medical devices, semiconductors and related technologies, food products, aviation, petroleum, coal, broadcasting, gaming, software, industrial and building products, chemicals, energy generation, and retail sales.

She has also successfully defended non-merger investigations, including investigations of alleged market allocation and violations of Section 8 of the Clayton Act, and 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, Rebecca's clients benefit from her extensive experience advising on issues relating to the Hart-Scott-Rodino Antitrust Improvements Act of 1976 (HSR Act), including proposed transactions' global premerger notification requirements. 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.

A significant portion of Rebecca's practice is devoted to advising clients on critical antitrust risk issues relating to business initiatives such as joint ventures, pricing and distribution strategies, information and data-sharing and trade association and industry-wide collaborative efforts.

Her antitrust counseling practice also covers such work as conducting antitrust compliance audits, analyzing liability exposure and recommending corrective action, as well as creating and presenting in-house training programs for client legal departments and business units. She has additionally developed and implemented corporate antitrust compliance policies, and online antitrust compliance training programs.

Rebecca's civil litigation experience includes defending allegations of price-fixing, bid-rigging and group boycotts in federal and state courts for clients in industries including construction materials, insurance, financial services and transportation.

She serves as the chair of the White & Case Washington Office Women's Network, and her recent pro bono activities include leading a team to advise Oxfam International on a variety of international human rights issues.
