Implementation of the National Security and Investment Act 2021

18 August 2022

The National Security and Investment Act came into force on 4 January 2022, and has materially impacted the M&A landscape in the UK. In this article, Alex Nourry, Daniel Harrison and Jordan Bernstein provide an overview of the Act and the changes to foreign investment review in the UK since it came into force. They explain the aspects of the Act most pertinent to deal parties, and explore the ways in which the Act's application should become clearer as more deals are subjected to review under it.

The authors are Alex Nourry, Partner, Daniel Harrison, Knowledge Director, Antitrust Practice and Jordan Bernstein, Associate, Clifford Chance LLP.
