The Federal Trade Commission (FTC) and the Department of Justice (DOJ) have announced a shift in their antitrust enforcement approach, calling for case-by-case evaluations following the withdrawal of longstanding competitor collaboration guidelines. This change was highlighted during recent legal proceedings, including the FTC's amicus briefs in the Epic Games v. Google case, where the agency urged the court to uphold a remedy, and in Musk v. Altman, where the FTC clarified laws regarding interlocking directorates and unfair competition. Additionally, the FTC's recent ruling in FTC v. Tapestry emphasizes the importance of documentary evidence over witness testimony, reflecting the influence of the 2023 DOJ Merger Guidelines. The regulatory landscape is further complicated by ongoing litigation, such as the blocked merger between Kroger and Albertsons, which underscores the heightened scrutiny of mergers and acquisitions in the current business environment.
