Costco Wholesale Corporation (COST)

Executive Summary

Costco Wholesale is the cleanest moat in retail and — at $1,050 — the most expensive way to own that moat we have seen in our analytical careers. The business is built on a structurally elegant model: members pay an annual fee for the privilege of buying groceries, electronics, gasoline, and a rotating assortment of treasure-hunt merchandise at break-even gross margins. Membership fees — $5.3 billion in fiscal 2025 at essentially 100 percent incremental margin — fund the operating expense base. Merchandise margin is the byproduct, not the engine. That is an unusual income statement, and it produces unusual durability. The financial signal is overwhelming.
