CFIUS’s annual report offers statistics based on the number of filings CFIUS receives, and on that basis, CFIUS seems to be about as busy as in recent years. However, the number of filings is not really an accurate reflection of CFIUS’s caseload because of double counting. Nearly 15 percent of the short-form declarations that were filed in 2024 ended up being resubmitted as long-form notices. Meanwhile, over 20% of the 2024 cases based on long-form notices (a slight uptick from 2023) could not be resolved within CFIUS’s statutory timeframe. Those cases had to be withdrawn and refiled administratively to allow CFIUS and/or the parties more time for diligence or to reach agreement on mitigation conditions.
After addressing the double counting of filings for the same transactions, we found that CFIUS looked at 264 distinct transactions during 2024, a 5 percent decline from 2023 and nearly 18 percent fewer transactions than in 2022. This is despite CFIUS’s renewed efforts at bringing in previously “non-notified” filings (transactions for which neither a mandatory nor a voluntary filing was made).
CFIUS’s falling caseload cannot just be a reflection of global M&A markets. As noted in our other recent blog posts covering the annual reports from foreign investment regulators in the United Kingdom and France, those countries are experiencing rapid growth in the number of filings, to the point where the UK has clearly leapfrogged CFIUS in terms of activity and even though half of French filings were determined by the French authorities to be out of scope, the French Treasury looked at more foreign investment filings in 2024 than CFIUS did.
Please see Table 1 below for our summary and suggested rethinking of the CFIUS statistics for 2022-2024.
In 2024, CFIUS applied mitigation conditions to fewer than 10 percent of the transactions it reviewed (not counting the one case in which CFIUS applied interim conditions during its review process). This is a remarkable drop—not only is it just over half of the mitigation rate from 2022 and 2023, but it is the lowest rate since 2015.
Notably, this change occurred before President Trump issued the America First Investment Policy, stating his intention to eliminate “overly bureaucratic, complex, and open-ended ‘mitigation’ agreements for United States investments from foreign adversary countries.” The implication of AFIP is that more investments from adversarial nations should be blocked, not mitigated. We’ll see if that further reduces the number of investments, and ultimately filings, from China, which the U.S. government has clearly tagged as an adversary. Although the rate of CFIUS’s mitigation conditions has fallen, as of 2024, CFIUS’s rate of clearing transactions has remained relatively steady.
The origins of foreign investments can vary from year to year for a variety of reasons, but in 2024 we saw a number of notable shifts. As indicated in Table 2 below, filings originating in Canada, China, Singapore, South Korea, and the United Kingdom continued to fall over the past two years, while filings from France and Japan continued to rise quickly. Declining filings from China likely reflect increasing geopolitical tensions between China and the United States, and arguably, the ongoing filing declines from Canada and the United Kingdom may reflect greater familiarity and use of CFIUS’s “excepted investor” status, which exempts certain investors from those countries from CFIUS’s mandatory filings as well as jurisdiction over non-controlling investments and real estate transactions. The other declines are harder to explain, as is the rapid growth in filings from France and Japan.
Unsurprisingly, the report includes CFIUS’s biggest case of the year, Nippon Steel-U.S. Steel, though it falls short of providing an explicit discussion of the case. The record shows that the Nippon Steel-U.S. Steel case was filed and withdrawn and refiled, ultimately leading to a Presidential decision to block the transaction. The annual report includes figures for cases that were withdrawn in 2024 and refiled in 2025, but there’s no statistic reflecting the fact that despite the Presidential decision in 2024, the Nippon Steel-U.S. Steel case was reopened and the decision ultimately reversed by a new President in 2025, with the introduction of a U.S. government-owned “golden share” in U.S. Steel as a mechanism for implementing CFIUS mitigation conditions. We are curious as to whether the classified version of the annual report delivered to Congress provides more insights, and look forward to next year’s annual report to see how CFIUS covers this unprecedented development.
