On behalf of a putative class of prescription drug buyers, plaintiff alleged that Rite Aid reported inflated “usual and customary” drug prices to the pharmacy benefits managers which transmitted the inflated figures to plaintiffs’ health insurers, causing the plaintiffs to pay higher than proper deductibles for the drugs. This decision affirms an order denying Rite Aid’s motion to compel arbitration. Only Rite Aid’s contract with the pharmacy benefit managers contained an arbitration clause. Plaintiffs’ claim did not depend on proving that Rite Aid had breached that contract, but only on proof that it supplied incorrect information to the managers causing plaintiffs to pay more than they should have. Therefore, plaintiffs were not equitably estopped from claiming they weren’t bound by the arbitration agreement.
