Contemporaneously with filing bankruptcy on October 16, Rite Aid filed an adversary proceeding against McKesson over a terminated supply agreement. McKesson supplies up to 98% of Rite Aid's prescription and over-the-counter drugs leading to a $667mn administrative claim. The parties resolved the adversary proceeding with a settlement that includes granting McKesson super-priority administrative status and a shorter turnaround. However, outside a settlement with Rite Aid in terms of the chapter 11 plan, the size of the $667mn administrative claim has the potential to render Rite Aid administratively insolvent.
