Samer’s practice focuses on antitrust merger advocacy in strategic and private equity transactions and also representing and counseling clients through all phases of litigation before the DOJ and FTC.

His experiences cover a wide range of industries, including medical devices, banking, airlines, telecommunications, fintech, wireless baseband chips, mining and material handling equipment, industrial materials and the locomotive and railroad industries. While at the Antitrust Division, Samer served as litigation and trial counsel in a number of the Antitrust Division’s most high-profile matters in the past decade. He recently served as lead trial counsel and first chair in the DOJ’s successful challenge to the merger of leading automotive aluminum autobody sheet suppliers in United States v.

Notably, Samer also served as trial counsel for the DOJ in opposing the proposed merger of two of the largest insurance companies in the United States in United States v. Aetna, Inc. and Humana Inc. The case resulted in verdict and judgment in the United States’ favor. In recognition of his achievements at the Antitrust Division, Samer was honored with numerous DOJ awards. Prior to joining the Antitrust Division, Samer was in private practice as an antitrust lawyer in Washington, D.C., where he represented and counseled clients through all phases of litigation, merger review, and pricing and distribution practices before the DOJ and FTC.
