Quinn Emanuel Urquhart & Sullivan LLP is bringing on former U.S. Securities and Exchange Commission litigator Sarah Heaton Concannon as a partner.
She was senior trial counsel at the SEC, working on investigations and enforcement actions on a range of issues involving issuer, investment adviser or broker-dealer fraud. Prior to joining the SEC in 2016, Concannon was an equity partner at Goodwin Procter.
Concannon joins Quinn Emanuel in Washington as the Biden administration gets ready to ramp up enforcement of federal securities laws against insider trading, market manipulation and investment adviser misconduct, among other issues.
“We will see significantly more ambitious regulatory conduct in the securities area,” Concannon said in an interview, “maybe not in six months but over time.”
In 2018, Concannon led the SEC effort that obtained a court order freezing more than $27 million in trading proceeds from allegedly illegal distributions and sales of restricted share of financial technology company Longfin Corp.
She represented the commission in federal court and in administrative proceedings across the country, and has also been involved in cases involving auditor and gatekeeper improper professional conduct, and violations of the Foreign Corrupt Practices Act (FCPA).
During 14 years at Goodwin Procter, she handled complex business litigation, including representing a large international bank in four actions in New York Supreme Court, and a related matter in California Superior Court, involving fraudulent inducement, misrepresentation and breach of contract actions.
“We are delighted to welcome Sarah to the firm,” said firm founder John B. Quinn, in a statement. “She is a first-chair securities trial lawyer of the first rank and brings a wellspring of talent to our work in this important area.”
He also praised her “substantive expertise in dealing with financial services companies, in antitrust, in cryptocurrency, and in other important areas of commercial litigation.”
