The essentials

  • Membership-fee annuity ($5.3bn, ~51% of operating income, 92.3% renewal) sitting atop a near-cost retail operation (~11% gross margin). The world's best retailer, wide moat.
  • Demonstrated pricing power: raised the fee in Sep-2024 (the first since 2017) without hurting renewal or member growth (+6.3%). E-commerce +21%, international growing faster.
  • But at ~$961 (~48× P/E, 2.1% earnings yield < 4.5% Rf) the price discounts perfection → Overvalued: the best business in the group at the worst price.

Total return at 5 years: -1.7%/year = -2.6% appreciation + 0.9% dividend. The target price ($842) is ex-dividend; the $39 in dividends collected over 5 years are added separately.

By both methods, the value today (DCF $693 · Multiples $710) is below the market price ($961).

Pillars of the analysis

The verdict — today vs 5 years

Today — expensive, no margin of safety: at $961 trades ~35.4% above its value discounted to today (~$710); the expected return does not even reach the risk-free rate (4.5%).

At 5 years — Sobrevalorado: the expected total return is negative — the price already discounts a demanding scenario that, if not met, results in a loss.

The bridge: the return at 5 years falls below the risk-free rate (4.5%) — which is why there is not even a discount to today's value. To require a 15% annual return, it would need to be bought at ~$444.

Thesis

The business

Costco is probably the world's best retailer: a membership-fee annuity (92% renewal, ~51% of operating income) with demonstrated pricing power, sitting atop a low-cost retail operation that generates volume and loyalty. The moat is wide and stable, return on capital is extremely high, net cash is growing, and growth has a runway (warehouses, international, e-commerce, fees). The one drawback is the valuation.

The valuation

It is valued on P/E over earnings: the business is a single-multiple business (the membership annuity is the narrative for why the multiple is premium, but it is not broken out as a separate piece). Today's earnings yield is ~2.1% — it does not even cover the risk-free rate (4.5%).

The base scenario projects a value of ~$842 per share over five years, an annual return of ~-2% from the current ~$961. At today's price it trades at ~48× earnings —a software-like multiple for a thin-margin retailer— and, even at a premium exit multiple (~27×, well above a normal retailer), it compresses toward ~31× over five years. The compression of the multiple from ~47× eats the earnings growth: the price already discounts perfection.

The margin of safety

The verdict is Overvalued: No margin of safety: the price already discounts a demanding scenario.. At ~$961 the expected return (~-2%) falls short of the required average return (10%): Costco compounds earnings ~9-10% a year, but the ~47× multiple already discounts that, so reversion toward a premium-but-normal multiple (~27×) neutralizes the growth. There is no margin of safety at this price — it is the best business in the group at the worst price in the group. The periodic special dividends (from the net cash) add an additional return, but they do not change the picture.

What to watch

The business itself barely needs watching (92% renewal, comps accelerating, fees with demonstrated pricing power) — what needs watching is the multiple. At ~47× any stumble (a comps slowdown —June already fell from +12.5% to +8.8%—, tariff pressure on the thin margin, Amazon's competition) triggers a large re-rating. The value trigger would be a much lower entry price: Costco is a business to buy on a pullback, not at 47× earnings.
