The FTC has implemented new antitrust regulations that require companies to disclose more information about mergers and acquisitions. This represents a significant change in regulatory oversight.

The changes were approved by the FTC with unanimous support, including from the agency's Republican commissioners who have previously opposed other initiatives led by Chair Lina Khan. The updated rules relate to compliance with the Hart-Scott-Rodino Act and were developed through discussions involving the FTC's top competition staff and the Justice Department's antitrust division.

This collaborative effort suggests a potential shift in antitrust enforcement, as the agency aims to increase scrutiny of corporate consolidations and ensure fair competition in the market.
