The Hart-Scott-Rodino Antitrust Improvements Act of 1976 (“HSR Act”), as amended, requires all companies and individuals engaged in certain mergers or acquisitions that meet or exceed the notification thresholds (shown below) to file a premerger notification with the Federal Trade Commission’s Premerger Notification Office and the Department of Justice Antitrust Division before consummating the transaction. The jurisdictional filing thresholds are adjusted each year, and the FTC published the new jurisdictional filing thresholds on January 14, 2026. These changes will become effective 30 days after their publication in the Federal Register, on February 17, 2026.
