Our advice helps mitigate risk in sensitive cross-border M&A

As they juggle national security and economic priorities, governments around the world are reshaping their investment review regimes. Over 100 jurisdictions now have laws that require governmental review of transactions on national security, public order, or similar grounds that seek to assess the threat that such investment may pose.

Freshfields provides the foreign investment expertise that drives successful cross-border M&A. We provide cutting edge insights into governments’ economic, political and national security considerations, giving you strategic advantage. Our integrated global team offers experience-based advice and representation.

Our on-the-ground teams around the world forge strong relationships with relevant authorities so our clients are always ahead of developing FDI and national security policy. The result is a string of client successes in some of the most complex transactions that have come before foreign investment regulators.

The Committee on Foreign Investment in the United States continues to scrutinise investments by non-Chinese investors for their ties to China, even as it shifts its targeting of China to new US regulations restricting investments by US persons into China. In China, investors are faced with twin foreign investment regimes that balance openness and security. In Europe, the European Commission has proposed tougher minimum standards for national reviews which would lead to a higher number of filings.

Our industry-leading expertise in FDI and cross-border M&A enables our clients to navigate increasingly stringent global regulations. Notably, former career heads of CFIUS from the US Department of Treasury, Aimen Mir and Brian Reissaus, are part of the Freshfields team. With their combined experience, Freshfields has overseen the review and disposition of nearly every transaction presented to CFIUS from 2009-2023.

In the face of heightened geopolitical tension and economic nationalism, Freshfields helps firms in all sectors achieve their international ambitions.

Essential Antitrust #15: Focus on fintech deals: navigating a tougher regulatory environment

Fintech M&A is booming, but so is regulatory scrutiny. Competition authorities are increasingly bullish to claim jurisdiction over fintech deals and to pursue novel theories of harm. At the same time, the scope of foreign investment regulation has widened due to the pandemic and ongoing trade tensions, adding yet another piece to the regulatory jigsaw puzzle faced by deal-doers. Getting your fintech deal cleared is no longer a given, and even if you get your merger control and foreign investment clearance, there is still a host of other financial regulation that applies before, throughout and after the deal process.
