Summary
A New York federal court's blockade of Henkel's proposed $725 million acquisition of Liquid Nails, the construction adhesives brand held by American Industrial Partners, represents a watershed moment in FTC merger enforcement. The August 14, 2026 decision, which imposed a permanent injunction halting the transaction, handed the Federal Trade Commission a significant courtroom victory and has prompted legal practitioners to recalibrate merger litigation strategy.
The ruling signals a shift in merger challenge dynamics. Rather than viewing FTC opposition as a negotiation tactic or preliminary hurdle, merging parties must now anticipate full-blown federal litigation, including complete evidentiary trials and the marshaling of comprehensive legal defenses. Attorneys at leading firms like Cooley have begun advising clients that the traditional path to deal completion—securing preliminary relief or negotiating settlements before trial—can no longer be assumed.
The Henkel-Liquid Nails outcome demonstrates that courts are willing to grant permanent injunctions when the FTC presents sufficient evidence of competitive harm. For dealmakers and their counsel, this development requires a fundamental recalibration of deal timelines, litigation budgets, and risk assessment protocols. The transaction's failure underscores the heightened stakes in contested merger reviews and reflects an increasingly assertive posture by federal authorities in blocking transactions they view as anticompetitive.
