CFIUS
US Committee on Foreign Investment — reviews acquisitions of US businesses by foreign buyers for national-security risk.
CFIUS jurisdiction is broad: any acquisition (or even non-controlling investment with board rights) by a non-US person in a US business that touches critical technology, infrastructure, or sensitive personal data. Voluntary filings are common; mandatory filings apply in specific TID-US business categories. UK NSI, EU FDI screens, and similar regimes have proliferated since 2020 — diligence now treats foreign-investment review as a standard workstream.
