The team at Simpson Thacher & Bartlett LLP is geared to support clients in assessing and minimizing CFIUS risk, seeking approval of large transactions with minimal or no conditions, and complying with mitigation agreements. Remaining a first port of call for the private equity industry, the practice stands out for its representation of large asset managers before CFIUS on high-profile and complex acquisitions and investments, while representing a wide range of corporations, financial investors, and sovereign wealth funds. The group demonstrates proficiency across an array of sensitive industries, including technology, semiconductor manufacturing, and telecommunications. It is particularly well-placed to advise China and Hong Kong-based companies and investment firms on responding to non-notified inquiries and negotiating mitigation agreements. Malcolm (Mick) Tuesley leads the national security regulatory practice and is very experienced in the CFIUS arena, having provided guidance on highly sensitive investments. Another key team member is Mark Skerry, who has experience securing CFIUS approvals in sensitive industries and negotiating complex mitigation measures. Jennifer Ho is also of note.
