In November 2026, thirteen states and the Federal Trade Commission filed a complaint seeking to enjoin Covetrus Inc. and its owners, Clayton, Dubilier & Rice LLC and TPG Inc. from acquiring MWI Veterinary Supply Inc. from its parent, Cencora Inc. The complaint alleges that the transaction would combine the two largest suppliers in the markets for veterinary clinic distribution and distribution to large corporate accounts, resulting in higher costs for veterinary clinics, decreased service quality, and increased prices for pet owners.
