On December 29, 2025, Chief Judge Lance Walker of the U.S. District Court for the District of Maine granted the plaintiffs’ motion for a preliminary injunction in American Hospital Association v. Kennedy. The court enjoined implementation of HRSA’s 340B Rebate Model Pilot Program “pending further order,” blocking the program from going into effect on January 1, 2026 (and April 1, 2026 for one manufacturer).
