Costco is a premier mature compounder generating highly predictable, high-margin membership fee revenue. However, the current market price of $1,011.71 implies an unsustainable >15% 10-year growth rate and a 45x terminal multiple, driving our $533.50 fair value and a Sell rating. Fair value range: low $385, high $683, with mid-point at $534.
