Costco posted a strong quarter with net sales up 11% year-over-year, clearing Wall Street's revenue bar with room to spare. Same-store sales rose 9.8% in the third quarter — partly lifted by gasoline — while adjusted comparable sales grew 6.6%, both figures outpacing rival big-box retailers. On the labor front, the company's CEO pushed back on automation fears, framing AI as a tool that enhances workers rather than replaces them.
Costco's consistent ability to beat comparable sales estimates signals that its membership model is holding consumer loyalty even in a value-conscious environment — a meaningful read on middle-to-upper-income household spending. For investors, strong comps relative to competitors like Target and Walmart suggest Costco continues to take market share, supporting a premium valuation. The CEO's public stance on AI and labor is also a reputational asset — Costco's worker-friendly brand directly reinforces membership retention.
Costco's next quarterly earnings release (fiscal Q4 2025, expected September 2025). Monthly retail sales data from the U.S. Census Bureau, next release mid-July 2025. Walmart and Target earnings in mid-August 2025 for sector comparison.
