Costco Wholesale (COST) Posts 13% Sales Growth, Is It Fully Priced?

Costco Wholesale (COST) just reported September net sales of US$30.02b, up 13.0% year on year, with management pointing to stronger comparable sales, faster delivery, and expanding digital pharmacy offerings as key business drivers.

Recent trading reflects that momentum. Costco Wholesale’s share price is up 4.66% over the past month and 10.82% year to date, while the 5-year total shareholder return of 120.87% indicates longer-term compounding from price gains and dividends.

Bulls see Costco Wholesale’s recent sales jump and digital pharmacy push as validation of a premium, while bears argue the share price already reflects that strength. Which side does the current valuation lean toward?

Most Popular Narrative: 9.9% Overvalued

Costco Wholesale last closed at $946.92, while the most followed narrative fair value sits at $861.94. This points to a premium that hinges on how durable its membership and margin story really is according to LunaRodas.

The pricing-investment commitment fared similarly well. Where the prior call promised only that Costco intended “to return to our members in some form the portion of tariffs that were passed on to them,” Ron Vachris now points to specific categories, produce, meat, beverages, home furnishings and hardware, where refund dollars became price cuts in the back half of the quarter. Unit growth “has been fantastic,” he says, tying the investment directly to volume response in pharmacy and the core business. It is one of the cleaner examples in this call of a vague commitment becoming a measured outcome.

Result: Fair Value of $861.94 (OVERVALUED)

Still, Costco Wholesale’s narrative could be tested if membership growth keeps slowing or if tariff refunds and related price cuts fade faster than expected.
