Rite Aid during the crisis is normal, panic people stocking up medications and the supply of workforce have decrease due to the reduced revenue.
Vertical Integration exist with Rite Aid as they have and own their own Pharmacy Benefit Manager (PBM), which is a third-party administrator of prescription drug programs for commercial health plans, self-insured employer plans, Medicare Part D plans, the Federal Employees Health Benefits Program, and state government employee plans. This will help Rite Aid reduce cost and increase their revenue. In the eyes of many, this will give other pharmacies a disadvantage, but in this age where pharmacies are growing and became more competitive, it is necessary. For example, CVS bought out Aetna, which will affect businesses as they will require their customers to get their medications at CVS to reduce cost, since its the same company. Please look at the picture below to see how it works.
