Partner, Co-Chair Executive Committee/Board and U.S. Chair

Adam is Co-Chair of the Executive Committee and Board and U.S. Chair.

One of the most preeminent lawyers in the US, Adam maintains a trial, investigations and counselling practice focused on bet-the-company matters. He has been described in Chambers USA as “the complete package” and The American Lawyer has repeatedly named him “Litigator of the Year”, most recently in 2023.

Uniquely versatile, Adam is the only lawyer recognized by Chambers USA for each of Securities Litigation, Antitrust Litigation, and Financial Services Enforcement and Investigations.

Adam is also one of only four lawyers in New York recognized by Chambers USA as a “Star Performer” for Securities Litigation, a special designation above Band 1. Law360 has selected Adam for its prestigious “MVP” recognition five years in a row. Forbes named Adam one of America's "Top 200 Lawyers," Benchmark Litigation has named him its sole “Securities Lawyer of the Year” four times, and The Legal 500 has named him to its “Hall of Fame.”

Adam represents corporations, directors, executives, special committees, financial institutions and asset managers in their highest stakes matters at trial and on appeal, in internal investigations, and before government enforcers, especially the DOJ, SEC, CFTC, state attorneys general, bank regulators and FINRA. Adam has a particularly deep focus on cases and investigations involving securities, corporate governance, M&A, antitrust and competition, derivatives and commodities, insider trading, SPACs, financial disclosure and accounting, trading and investment banking regulation, general commercial matters and insolvency.
