In February 2025, new rules for the pre-merger notification requirements in the U.S. came into effect. But will a February 2026 court decision undo these changes? Daniel Rosenthal, partner at Kirkland & Ellis, joins Jaclyn Phillips and Lexi Michaud to discuss a decision vacating the new rules, the subsequent appeal, and what might happen next. Listen to this episode to learn more about how to navigate merger filings in an uncertain time.
(Since this episode was recorded, the Fifth Circuit denied the FTC's motion to stay the decision vacating the new HSR Rules.  On March 19, 2026, the Premerger Office announced that the Commission is now accepting HSR filings using the Form and Instructions that were in place before the February 10, 2025, effective date of the new rule.  As always, continue to follow the case and consult a lawyer for any legal advice.)

Over the last few decades, prior approval requirements were considered an extraordinary remedy in merger settlements, yet their use has fluctuated in agency enforcement across recent administrations. Where do the FTC and DOJ stand in their current practice?

States have become increasingly active participants in merger enforcement, often conducting independent analyses and, at times, intervening alongside federal agencies in high-profile cases. What goes into states' analyses and decisions to intervene? Anthony Mariano, Chief of the Antitrust Division at the Massachusetts Office of the Attorney General, speaks with Lexi Michaud and Anora Wang about how states approach merger enforcement in parallel with the DOJ and FTC, the importance of independent state scrutiny, and, using the HPE–Juniper transaction to guide the discussion, how the Tunney Act promotes transparency and public interest oversight of federal settlements.
