Capabilities / CFIUS


Practical, efficient legal counsel on cross-border transactions implicating national security.

Bringing together M&A, international trade, and national security law practitioners, Husch Blackwell provides end-to-end legal counsel to buyers and sellers whose transactions might trigger review by an increasingly active Committee on Foreign Investment in the United States (CFIUS). Our diverse and experienced team collaboratively advises clients at each point on the transactional timeline, beginning with an initial assessment of CFIUS risk, filing options, and applicable requirements. We know time is of the essence and quickly frame the key issues for clients as early as possible.

If a decision is made to file, our team ensures a seamless partnership between transactional lawyers and regulatory specialists—including professionals in related practice areas—and walks clients through each step of a complex process that can often make or break a deal. 

Our team also includes former government officials who understand recent trends and changes—including the impact of CFIUS reform legislation—and provide invaluable insight into how CFIUS assesses cross-border transactions. Our attorneys and professionals also keep close tabs on the dynamic regulatory and policy environment of which CFIUS is a part.

Representative Experience

  • Represented an entity owned by the municipal government of Beijing in the acquisition of a U.S. semiconductor company, which was one of the few Chinese acquisitions approved by CFIUS in 2017.
  • Advised a U.S. company on CFIUS review related to the contemplated divesture of its semiconductor component testing business. The seller produced a sophisticated product and was planning to transfer the design technology and an assortment of other software and production technology for that product to a buyer that was at least partially owned and controlled by the Chinese government. We determined that the transferred assets did not qualify as the sort of “critical technologies” that would trigger a mandatory CFIUS declaration, but raised other concerns associated with this transaction due to the export classification of the seller’s products. As a result, the client ultimately decided to abandon the transaction.
