COST

Costco’s moat remains its membership-fee annuity layered onto a high-velocity warehouse model that keeps prices structurally low and drives traffic. Q2 FY2026 showed the model is still scaling: total comparable sales were up 7.4% (6.7% ex-gas/FX) and digitally enabled comp sales rose 22.6%, supporting omnichannel relevance. Continued warehouse growth (924 locations as of March 2026) and ancillary expansion (including gas) reinforce convenience and value, while peers’ fee hikes suggest pricing power is industry-wide.

Financially, Costco is a low-margin retailer with unusually high earnings quality because membership fees carry outsized profit contribution; in Q2 FY2026, membership fees were $1.355B. Q2 FY2026 net sales were $68.24B (+9.1% y/y) with net income of $2.035B and EPS of $4.58; for FY2025, net income was $8.099B (diluted EPS $18.21). Valuation is the key tension: the stock trades around ~51–52x trailing earnings, leaving little room for execution slips despite steady comp and renewal resilience.

Thesis: Costco is a premium-quality defensive grower, but investors are paying a premium multiple that already assumes durable mid-to-high single-digit comp growth and ongoing membership monetization. Over the next 12 months, catalysts include continued post-September 2024 fee increase tailwinds, sustained 20%+ digital momentum, and steady international comps; key risks are multiple compression, any renewal-rate wobble, and margin pressure from wage/merchandise costs.

Recommendation: HOLD. The business is compounding predictably, but the current valuation is the main risk, and upside likely requires either faster growth than recent trends or a further multiple expansion.
