Costco Wholesale Corporation

COST · NASDAQ · USD

Can Costco keep growing sales and members at its recent rate while cutting prices, absorbing tariff and input cost inflation, and funding a larger warehouse pipeline?

Last 4 earnings calls · through Q4 FY2026

Bull case

  • Price-led market share gains

    The bull case is that Costco's price-first model keeps winning share, so its sales grow faster than the categories it competes in.

  • Warehouse and digital expansion

    New warehouses and digital channels compound that growth, and management says each new building matures faster than the last.

  • Membership fee earnings

    Membership fees and executive upgrades supply recurring high-margin income that rises as loyalty and spending deepen.

  • Price reinvestment capacity

    Cost savings and tariff refunds are pushed back into lower prices, which defends traffic when rivals also cut prices.

Bear case

  • Slower member sign-ups

    The bear case is that member sign-ups have slowed, and the outsized lift from opening in brand-new countries has not repeated.

  • Input cost inflation

    Memory chips, fuel-linked materials and health care costs keep rising while Costco cuts prices on everyday items, narrowing margins.

  • Heavier capital spending

    Capital spending has stepped up for warehouses, depots and technology, absorbing cash that previously went to shareholders.

  • Tariffs and product mix

    Tariffs keep resetting landed costs, and a larger share of sales from thinner-margin gasoline weighs on the blended margin rate.

Bull and bear points

Growth & Execution

In short: Sales and membership keep growing, though sign-ups have slowed and traffic is nearer its historical norm.

Bull · 2

  • Renewal rates turned up after management warned of declines

    Earlier calls warned renewal rates could keep slipping for a few quarters. This quarter both the U.S./Canada and worldwide rates rose 10 basis points, which protects the membership fee base.

  • Management plans 33 warehouse openings in fiscal 2027

    That keeps Costco on its stated path of 30 or more net new warehouses a year, split between U.S. infills and new international markets. Openings are the main source of new members and incremental sales.

  • Paid member growth has slowed to under 4%

    Costco ended the year with 84.1 million paid members, up 3.8%. Slower growth in new households means less of the spending increase that arrives as members mature.

  • Traffic growth has settled near 2% from mid-single digits

    Shopping frequency is growing far more slowly than a year ago, so comparable sales now lean on basket size and gasoline prices rather than on more visits.

Profitability & Financial Strength

In short: Membership fees and cash are strong, while price cuts and heavier capital spending limit the earnings cushion.

Bull · 2

  • Executive memberships keep climbing and renew more often

    Costco ended the year with 42.3 million executive members, up 9.4%, and those members spend more and renew at higher rates. Fee income carries almost no incremental cost.

  • Net cash keeps building on strong free cash flow

    Costco held $15.1 billion of net cash at year end, up from $9.5 billion a year earlier. That funds the warehouse build and the dividend without adding debt.

  • Core merchandise margins have turned from expansion to decline

    Earlier calls highlighted core-on-core margins up 30 basis points. By the third quarter that measure was down 9 basis points as Costco cut prices on eggs and beef and absorbed higher transport costs.

  • Capital spending rises to $7.5 billion in fiscal 2027

    Capital expenditure rose 17% to $6.4 billion last year, and management guides to about $7.5 billion next year for warehouses, depots and technology. That is cash not available for dividends or buybacks.

Market Position

In short: Pricing authority supports share gains, while tariffs raise costs and a fuel-heavy sales mix dilutes margins.

Bull · 2

  • Gasoline price gaps pulled in record volumes and first-time users

    Costco widened its gasoline price gaps as fuel costs rose, reaching an all-time high in the share of U.S. member households buying gas. Management says gas customers shop more often, spend more and renew at higher rates.

  • Kirkland Signature gives Costco more control over supply

    Kirkland Signature items sell below national brands with equal or better quality, and leaning on them gives Costco more control over its supply chain when tariffs or commodity costs move.

    Q2 FY2026 call
Bear · 2

  • Tariffs keep resetting the cost of imported merchandise

    The IEEPA tariffs were replaced with new global tariffs running at least 150 days, so buyers must keep moving production and reworking assortments. Costco absorbs part of that cost to hold prices down.

    Q2 FY2026 call

  • A larger gasoline share of sales dilutes the margin rate

    Record fuel volumes made gasoline a larger share of sales, and gas earns a thinner margin than merchandise. A mix tilted toward gas lowers the blended gross margin rate even while total sales grow.
