Costco Wholesale reported $30.02 billion in net sales for its five-week retail month ended Oct. 4, with comparable sales up 11.4% and digitally enabled sales up 19%.

Net sales were 13.0% higher than the $26.58 billion recorded in the year-earlier period. Comparable sales increased 11.4% as reported and 7.6% after excluding the effects of gasoline prices and foreign exchange. Digitally enabled sales rose 19.0% during the month.

The monthly sales period followed Costco’s 16-week fiscal fourth quarter, which ended Aug. 30. Net sales for that quarter totaled $93.9 billion, up 11.2% year over year. Net income was $2.998 billion, or $6.75 per diluted share.

The quarter’s earnings included a nonrecurring benefit of $0.15 per diluted share from tariff refunds, net of partial reinvestment in member value. The benefit was part of the reported quarterly results.

For fiscal 2026, which ended Aug. 30, membership-fee revenue reached $5.907 billion, an 11% increase from fiscal 2025. Costco had 84.1 million paid members at fiscal year-end. Executive members accounted for about 75.2% of worldwide net sales.
