Costco Stock Rises on Strong September Sales Performance
Costco Wholesale reported an 8% year-over-year sales increase to $26.58 billion for the five-week period ending October 5, 2025, defying macroeconomic headwinds. The membership-based retailer's stock climbed 2% in extended trading following the announcement.
Comparable sales grew 5.7% globally, with particularly strong performance in international markets (8.5%) and digital channels (26.1%). The results extend Costco's momentum after better-than-expected Q4 fiscal 2025 earnings, demonstrating the resilience of its value-focused model.
