Costco Wholesale CorpStrong sales and digital growth are positive, but high valuation and analyst pullback warnings create mixed outlook.

Costco Wholesale reported strong operational momentum in May 2026, with net sales up 14.5% and digital comparable sales above 20%, while its third-quarter revenue grew 11.6% to US$70,527 million and e-commerce jumped 37%. Membership renewal held at 89.7%, but the stock trades near US$985 per share with a trailing price-to-earnings ratio near 49, prompting analysts to flag a potential pullback to the low US$900s as a better margin of safety. Investors are weighing whether accelerating digital growth can justify the premium valuation amid sticky inflation, cautious central bank policy, and early signs of membership renewal softness. Some optimistic projections see revenue reaching about US$376.8 billion and earnings of US$12.6 billion by 2029, yet the tension between strong fundamentals and valuation risk remains front and center.
