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.

The Trump FTC Takes New Action Against Non-Competes, While Abandoning Defense of the Biden-Era Non-Compete Clause Rule
Demonstrating its focus on challenging non-competes through case-by-case enforcement, the Federal Trade Commission (FTC) recently undertook a series of actions. It announced a consent decree requiring Gateway Memorial Pet Services (Gateway), the largest pet cremation business in the United States, to immediately cease enforcement of non-compete agreements that the FTC alleged “limit [employee] job mobility and the ability to negotiate better wages and benefits."1 Along with that action, the FTC also issued a broad Request for Information (“RFI”), inviting members of the public to provide information on non-compete agreements that they themselves may be subject to or have knowledge regarding so the FTC can investigate further and bring enforcement action as appropriate. The following day, the FTC announced it would abandon its appeals in Ryan, LLC v. FTC, No. 24-10951 (5th Cir.), and Properties of the Villages v. FTC, No. 24-13102 (11th Cir.), and to accede to the order in Ryan setting aside the Biden-era Non-Compete Clause Rule.

And Just Like That: Remedies Are Back at the FTC
The Federal Trade Commission (FTC or Commission) recently announced that it will require Synopsys, Inc. (Synopsys) and Ansys, Inc. (Ansys) (together, “the parties”) to divest certain assets to resolve antitrust concerns surrounding the parties $35 billion merger.1 The Proposed Order is the first instance of the Commission clearing a merger subject to a remedy under the new Trump Administration. The Commission’s willingness to resolve competitive concerns about a merger through divestiture confirms the return to the status quo—before the Biden Administration and FTC Chair Lina Khan—where parties to a merger may work with the FTC to find a structural solution that resolves the anticompetitive concerns presented by a merger while preserving its procompetitive benefits.
