Federal Court Vacates FTC’s 2024 HSR Form Rule; Order Stayed Seven Days Pending Appeal
On February 12, 2026, Judge Jeremy D. Kernodle of the U.S. District Court for the Eastern District of Texas granted summary judgment to plaintiffs U.S. Chamber of Commerce and other business groups, and vacated the 2024 Federal Trade Commission (FTC) rulemaking that significantly revised the Hart-Scott-Rodino (HSR) reporting requirements. The court concluded that the FTC exceeded its statutory rulemaking authority when it implemented the HSR reporting change, and such a change was arbitrary and capricious under the Administrative Procedure Act (APA). The court stayed its order for seven days to allow the FTC to seek an emergency appeal to the U.S. Court of Appeals for the Fifth Circuit. If the Fifth Circuit does not grant emergency relief before February 19, 2026, the current HSR rules will be vacated, and HSR reportable transactions will be filed under the HSR rules that were in effect prior to February 10, 2025, when the new HSR reporting rules went into effect.
