Shaoul Sussman

Shaoul is a Partner and Co-Founder of Simonsen Sussman LLP and a seasoned antitrust practitioner with extensive experience in private and government practice.

Most recently, Shaoul served as the Associate Director for Litigation in the Bureau of Competition at the Federal Trade Commission. During his tenure, he oversaw the Bureau’s expansive litigation portfolio, focusing on strategic case development and successful outcomes. During his time in the Bureau’s Front Office, Shaoul worked on several high-profile and complex cases including the Kroger-Albertsons merger challenge, which addressed consolidation in the retail grocery sector, and the FTC’s lawsuit to unwind Illumina's acquisition of Grail in the Fifth Circuit, the first successful challenge to a vertical merger in 40 years. Additionally, Shaoul played an instrumental role in the FTC’s landmark monopolization case against Meta.

Apart from his litigation work at FTC, Shaoul played a pivotal role in shaping the FTC and DOJ 2023 Merger Guidelines, which introduced new measures aimed at addressing market consolidation and modernizing merger enforcement standards to reflect contemporary market realities and economics. Shaoul led the efforts to reform the premerger notification process under the Hart-Scott-Rodino (HSR) Act. These reforms, which came into effect in 2025, included significant updates to streamline filing procedures, improve transparency, and strengthen regulatory oversight to ensure compliance with evolving antitrust laws. Shaoul also led the drafting of several amicus briefs filed by the U.S. government in landmark antitrust cases, including the FTC’s amicus brief during the remedy phase of the Epic v. Google case, which was cited favorably by the court.
