Ms Sara Razi > Simpson Thacher & Bartlett LLP > Washington DC, United States > Lawyer Profile

Simpson Thacher & Bartlett LLP leverages its strong profile within the private equity space, advising a number of major buyout funds on global antitrust filings and investigations, combining this work with a notable focus on complex public M&A approvals, offering deep agency experience on mandates facing Second Request investigations as well as antitrust lawsuits brought by the DOJ and FTC. The team is able to handle mergers in highly scrutinized industries, particularly healthcare, with Washington DC-based co-head Sara Razi successfully representing Change Healthcare in the DOJ challenge to its acquisition by UnitedHealth, as well as financial services. New York’s Peter Guryan co-heads the team and is a former Antitrust Division trial attorney, allowing him to handle contentious merger proceedings both domestically and internationally, and is particularly active on behalf of private equity-backed companies and funds. DC-based Preston Miller is an increasingly key team member, focusing heavily on merger review and playing a major role in the Change deal, with senior counsel Richard Jamgochian in New York also noted for his broad sector knowledge and work on antitrust risk analysis at the outset of deals.

Simpson Thacher & Bartlett LLP‘s highly active practice represents clients on multiple major new and ongoing cartel matters, leveraging the deep in-house experience of the team to represent clients in international and domestic investigations and subsequent litigation. Internal investigations, leniency applications, and multijurisdictional compliance programs are particular strengths of the group. The practice is jointly overseen by Washington DC-based John Terzaken, DC’s Sara Razi, as well as Peter Guryan in the New York office. Terzaken, the former director of criminal enforcement at the DOJ’s Antitrust Division and a leading name in the field, concentrates on market sector investigations and litigations across all major industries with an emphasis on financial services and fintech. Razi is a former senior official at the FTC, while Guryan formerly served as a trial attorney in the Antitrust Division. Jeffrey Knox, also based in DC, advises multinational corporations and independent board committees in high-stakes investigations by the DOJ, SEC, CFTC, and other federal and state enforcement regulators. Another key DC name is Abram Ellis, who regularly acts on follow-on cartel litigation.
