This client alert updates readers on the introduction of legislation in the US Congress that, if enacted, would result in significant changes to CFIUS, the U.S. government interagency committee that conducts national security reviews of foreign investments. These proposed changes are centered on foreign investment in U.S. companies involved in critical technology or critical infrastructure. The legislation is an effort to address a national security threat emanating from China and other U.S. adversaries. Foreign companies need to know how changes to US law would affect their decisions about where and how to invest. Hogan Lovells is activity monitoring the legislation and would be pleased to assist your company in navigating any statutory changes to the CFIUS process.
