Catherine Hein

Catherine Hein advises clients on transactions that intersect with national security regulations, with a particular focus on the Committee on Foreign Investment in the United States (CFIUS), the Outbound Investment Security Program, and the Office of Foreign Assets Control (OFAC).

Catherine helps foreign and domestic clients, including global market-leading companies, private equity funds, asset managers, and sovereign wealth funds, navigate the U.S. national security regulatory landscape.

She draws on extensive private practice experience with financial transactions as well as public sector service to help clients negotiate cross-border transactions, including with:

CFIUS reviews and mitigation agreements

U.S. economic sanctions

Restrictions on U.S. investment into China, Hong Kong, and Macau

She brings credibility and depth on CFIUS, advising on structuring and compliance strategies, along with versatility across sanctions and other related trade and national security issues.

Prior to joining the firm, Catherine served as Acting Principal Deputy Assistant General Counsel for Enforcement & Intelligence at the U.S. Department of the Treasury (Treasury), where she supported OFAC and the Financial Crimes Enforcement Network (FinCEN). She previously served as the CFIUS Managing Counsel at Treasury, where she led a team of more than 20 lawyers on foreign investment reviews by CFIUS. In these roles, she advised senior Treasury leadership and interagency stakeholders on policy, statutory authorities, and regulatory requirements in connection with foreign investment reviews, economic sanctions, and other U.S. national security matters. She worked extensively on all aspects of CFIUS cases, including non-notified transactions, negotiating complex mitigation agreements, and compliance and enforcement actions.

Given her experience working within Treasury and in private practice, Catherine frequently presents and writes on U.S. national security regulatory issues and developments.
