Mark Plotkin — broadly recognized as one of the nation’s preeminent regulatory advocates — represents clients before the Committee on Foreign Investment in the United States (CFIUS) and other branches of the U.S. government. He delivers outstanding results for global clients across industries. Mark’s practice includes having negotiated some of the most challenging compliance and security agreements ever concluded with the U.S. Government – agreements that in many instances now are the template for the relevant industries.

Clients refer to him as "the dean of the CFIUS Bar" with an "unmatched history, experience and network" (Chambers USA). The American Lawyer has twice honored Mark as "Dealmaker of the Year"— in 2016 for his role securing CFIUS clearance for GlobalFoundries’ multibillion dollar acquisition of IBM’s semiconductor unit, and again in 2019 for his team's successful and novel efforts in the CFIUS process to defend Qualcomm from a hostile takeover attempt by Broadcom.

Chambers Global says “Plotkin is widely regarded as one of the top national security attorneys in the USA and has extensive experience in advising industry-leading names before the CFIUS panel." He also is nationally ranked for his expertise in both financial services regulation and data privacy.
