Costco Surges on 8.7% Sales Growth as Global Resilience Drives E-Commerce and Volume Ranks 49th

On September 4, 2025, Costco (COST) traded at a volume of 1.41 billion, ranking 49th in market activity, with shares rising 0.64%. The company reported $21.56 billion in August net sales, up 8.7% year-over-year, driven by strong performance across all regions and e-commerce. Total sales for the 52-week fiscal year reached $269.9 billion, an 8.1% increase from the prior year.

Comparable sales growth highlighted regional resilience, with U.S. sales up 6.1% for the month and 5.1% for the fourth quarter. Excluding gasoline and foreign exchange impacts, U.S. growth accelerated to 6.7%, while Canada and international markets saw gains of 9.4% and 5.3%, respectively. E-commerce sales surged 18.4% in August, underscoring robust online demand.

Despite the positive figures, U.S. growth lagged slightly behind international markets, and forward-looking disclosures in the report emphasized risks such as economic volatility, inflation, and geopolitical factors. The company operates 914 warehouses globally and maintains e-commerce platforms in eight countries.

Historical data indicates that Costco’s stock has historically outperformed the market by 1.2% in the three months following similar sales reports, suggesting potential momentum for investors to monitor.
