United States: U.S. Merger Control Filings in H1 2023 Are Down Approximately 35% Compared to Same Period in 2022 While New Regulatory Hurdles to Mergers Have Been Announced

HSR premerger filings in January 1, 2023 – June 30, 2023 ("H1 2023") dropped 35% compared to H1 2022 and dropped 50% compared to H1 2021.

In late June 2023 and July 2023, U.S. antitrust authorities announced sweeping changes to the HSR premerger notification Form,1 and to the U.S. Merger Guidelines, replacing the 2010 Horizonal Merger Guidelines and the 2020 Vertical Merger Guidelines (collectively, the "Merger Guidelines").2 To read more about these developments and what they mean for you, visit White & Case's client alerts here and here.

The HSR Form and Merger Guideline changes are expected to go formally into effect in Q1 2024. These key developments – before and after implementation – will almost certainly affect U.S. premerger notification filing trends in the coming months.

European Union: H1 2023 Merger Filings Control Notifications Are Down Approximately 20% Compared to H1 2022

In Europe, merger control notifications to the European Commission during H1 2023 (January 1, 2023 – June 30, 2023) are down approximately 20% compared to the number of notifications in H1 2022 (January 1, 2022 – June 30, 2022), which may indicate a decline in the M&A activity in Europe. During H1 2023, the European Commission received 151 notifications, and of those, 143 transactions were cleared without commitments. Five of the notified cases went to Phase II in H1 2023, which is slightly more compared to three Phase II proceedings launched in H1 2022. Two (out of five) mergers that went to Phase II in H1 2003 were in the digital sector,3 compared to three4 (out of eight) Phase II digital mergers in the entire last year 2022. This suggests that the number of digital mergers investigated in Phase II in 2023 could be higher than in 2022.
