ISSAQUAH, Wash., September 24, 2026 - Costco Wholesale Corporation (“Costco” or the “Company”) (Nasdaq: COST) today announced its operating results for the 16-week fourth quarter and the 52-week fiscal year ended August 30, 2026.

Net sales for the quarter increased 11.2 percent, to $93.9 billion, from $84.4 billion last year. Net sales for the fiscal year increased 10.1 percent, to $297.2 billion, from $269.9 billion last year.

Net income for the fourth quarter was $2.998 billion, $6.75 per diluted share, compared to $2.610 billion, $5.87 per diluted share, last year. This year's fourth quarter was positively impacted by a non-recurring benefit of $0.15 per diluted share from IEEPA tariff refunds received in the quarter, less partial reinvestment of those refunds in increased member values. Net income for the fiscal year was $9.226 billion, $20.76 per diluted share, compared to $8.099 billion, $18.21 per diluted share, last year.

Costco currently operates 939 warehouses, including 647 in the United States and Puerto Rico, 115 in Canada, 43 in Mexico, 37 in Japan, 29 in the United Kingdom, 20 in Korea, 15 in Australia, 14 in Taiwan, seven in China, five in Spain, three in France, two in Sweden, and one each in Iceland, and New Zealand. Costco also operates e-commerce sites in the U.S., Canada, the U.K., Mexico, Korea, Taiwan, Japan, Australia, and China.

A conference call to discuss these results is scheduled for 2:00 p.m. (PT) today, September 24, 2026, and will be available via a webcast on investor.costco.com (click “Events & Presentations”).
