FTC Finalizes Major Rewrite Of HSR Filing Requirements

Last week, the Federal Trade Commission (FTC) voted unanimously to issue a final rule that implements significant changes to the Hart-Scott-Rodino (HSR) premerger notification form and accompanying instructions. While the final rule includes numerous modifications from the draft proposal that was announced in June 2023 (see our previous client alert), this still represents the most substantial change to the HSR filing requirements in decades, and will require parties to HSR-reportable transactions to gather and provide considerably more information and documents than under the current rules. The final rule will take effect 90 days after publication in the Federal Register (unless there is a successful court challenge in the interim).
