Our attorneys have extensive experience representing clients before the Committee on Foreign Investment in the United States (CFIUS) with respect to national security reviews of their M&A, PE/VC/CVC, joint venture, and real estate deals. U.S. as well as foreign companies and investors regularly seek our user-friendly guidance on navigating complex CFIUS laws and regulations, including the Foreign Investment Risk Review Modernization Act (FIRRMA) and its implementing rules.

We have evaluated hundreds of transactions to determine whether they trigger CFIUS filing requirements. In addition, we advise parties on CFIUS exemptions as well as effective strategies to mitigate their CFIUS risk if necessary. We have handled CFIUS matters for buy-side/investor clients domiciled in China, Japan, Korea, Europe, Australia, Latin America, and the Middle East. Our CFIUS experience covers the aerospace/defense, autonomous vehicles, semiconductors, technology (AI, software, social media, and big data), energy, mining, biotech/life sciences, and other sectors.

Rimon’s CFIUS practice stands out from its peers because not only are our attorneys well-versed in the intricacies of complex CFIUS regulations, many of them are also seasoned corporate practitioners who understand how deals work. This dual perspective enables us to be effective advocates of our clients’ interests in front of CFIUS and its member agencies. In addition, we have the resources necessary to guide our clients on national security reviews conducted by government agencies outside the United States, including in the United Kingdom, Canada, and Australia.
