Is CFIUS One of the Few Things Crossing the Atlantic?

Client Alert | 1 min read | 12.16.20

To date, the U.K. government has rarely used its power to intervene in M&A deals on the grounds of public interest, with only 12 transactions having been reviewed since 2013. This may be about to change. The National Security and Investment Bill (the Bill) if enacted would substantially reform the U.K.’s foreign investment rules, introducing a hybrid system of mandatory and voluntary notifications on grounds of national security similar to reviews by the Committee on Foreign Investment in the U.S. (CFIUS). The Bill, likely to become law in early 2021, is projected to lead to the notification of potentially 2,000 transactions per year. Critically, transactions completed on or after 12 November 2020 may be retroactively reviewed by the U.K. government once the Bill is passed into law.

Key points on the proposed regime:

  • 17 sectors are subject to mandatory notification, including defence, energy, AI and other technologies.
  • There are criminal and civil sanctions for breaches of mandatory notification obligations and other non-compliance, with fines of up to 5% of worldwide turnover or £10 million and up to 5 years imprisonment for directors.
  • Transactions under the mandatory regime which complete without clearance will be void.
  • Transactions can be retrospectively ‘called in’ for review up to five years after closing.
  • There will be no turnover or market share thresholds below which transactions will fall outside the regime.
  • Certain asset acquisitions (e.g. land, moveable property and intellectual property) will fall under the regime, as well as acquisitions of companies and other businesses.

The proposed regime is clearly an important development for M&A and FDI transactions involving the U.K. As a first step, overseas investors into the U.K. may wish to consider whether any of their recent transactions could be retroactively reviewed.

Developers Adapt Timelines and Strategies for Wind and Solar Projects Following Recent IRS Guidance and Expected IRS Enforcement Activity

On August 15, 2025, the Treasury Department and IRS released updated guidance concerning Beginning of Construction requirements to qualify for clean energy tax credits. This new guidance is critical for developers to consider as they rush to qualify for the tax credits before they expire entirely. The much-anticipated guidance followed the July 7, 2025 Executive Order 14315, Ending Market Distorting Subsidies for Unreliable, Foreign-Controlled Energy Sources (“July 7, 2025 Executive Order”), which signaled that the Trump Administration was planning to strictly enforce the termination of production and investment tax credits for solar and wind facilities that are set to expire under the One Big Beautiful Bill Act (OBBB Act), covered in more detail here. The new guidance comes at a time when many in the industry are struggling to keep up with the myriad ways that the new administration is working to roll back wind and solar tax credits, leaving developers to piece through the recent guidance to determine how best to structure and invest in clean energy projects given the volatile position of the current administration vis-a-vis wind and solar energy....
