On October 10, 2024, the Federal Trade Commission (“FTC”), with the concurrence of the Antitrust Division of the Department of Justice (“DOJ”), announced the FTC’s unanimous vote to adopt a final rule implementing significant changes to the reporting obligations under the Hart-Scott-Rodino Antitrust Improvement Act (“HSR Act”). Though not as extensive and burdensome as the original proposed changes (see our prior memo analyzing the proposed changes), these changes will increase parties’ filing burden and limit their ability to file quickly, even in non-problematic transactions. Absent judicial intervention, the final rule will become effective 90 days after it is published in the Federal Register (i.e., approximately mid-January 2025). The FTC also announced that, once the final rule goes into effect, it will lift the three-and-a-half-year “temporary suspension” of granting early termination of the HSR waiting period in transactions not needing further agency investigation.
