Antitrust in 2025 was marked by policy developments and antitrust enforcement that, while remaining aggressive, became less overtly anti-business. The U.S. continued a number of cases from the Biden administration, but became more open to settlements, while continuing implementation of the new and more burdensome HSR merger notification form and of the more aggressive and less economically focused 2023 Merger Guidelines. The European Commission conducted a series of DMA enforcement actions and launched a broad-sweeping consultation on the Merger Guidelines. The UK CMA continued a tack toward a more restrained approach to enforcement, taking greater account of growth and suggesting it would allow greater flexibility in merger remedies. The Chinese State administration for Market Regulation started to intervene in transactions below the filing thresholds and continued to keep antitrust in its toolbox for tackling geo-political tensions.

On Friday, the Court in Texas v. Blackrock issued an opinion largely denying defendants’ motion to dismiss, which allows a coalition of States to proceed with claims that BlackRock, State Street, and Vanguard conspired to violate the antitrust laws by pressuring publicly traded coal companies to reduce output in connection with the investment firms’ ESG commitments. The Court found that the States plausibly alleged that defendants coordinated with one another, relying on allegations that they joined climate initiatives, made parallel public commitments, engaged with management of the public coal companies, and aligned proxy voting on disclosure issues. It is worth noting that, while the court viewed BlackRock’s, State Street’s, and Vanguard’s participation in Climate Action 100+ and NZAM as increasing the plausibility of the claim in favor of denying the motion to dismiss, the Court clarified that it was not opining that the parties conspired at Climate Action 100+ or NZAM.

Antitrust in 2024 was marked by evolving policy developments, vigorous enforcement, and eye-catching court decisions. In the U.S., an aggressive enforcement approach lead to unpredictability and lengthy merger review process across sectors. In the EU, enforcement of the Digital Markets Act (DMA) intensified scrutiny on digital platforms, while a landmark ruling in the Illumina/GRAIL matter clarified the scope of the EU Commission’s merger jurisdiction. In the UK, the Competition and Markets Authority (CMA) cleared the Vodafone/Three merger with behavioral remedies, signaling a significant departure from its historic practice to require structural remedies. 2025 will see new antitrust leadership on both sides of the Atlantic with an expectation that the U.S. will largely return to a more traditional approach on antitrust under the Trump Administration and that Europe will continue to enforce digital rules and bring cases related to AI with a focus on promoting growth in clean tech and AI sectors.

On November 14, 2024, the U.S. Department of Justice (“DOJ”) Antitrust Division (the “Division”) released guidance for the Evaluation of Corporate Compliance Programs in Criminal Antitrust Investigations (the “Guidance”). The Guidance will be used by the Division in assessing the adequacy and effectiveness of a company’s antitrust compliance program when making a charging or resolution decision.[1]
