Costco reported net sales of $29.24 billion for June, a 10.6% increase from the year-ago period, but comparable sales growth decelerated to 8.8%, signaling a slowdown from the prior month’s stronger momentum as the membership warehouse operator navigates shifting consumer demand.
The retailer’s June comparable sales marked a sharp pullback from May’s 12.5% growth, according to Costco Investor Relations. For the five weeks ended July 5, 2026, total company comparable sales rose 8.8% year-over-year, well below the prior month’s pace.
The slowdown reflects a normalization after May’s outsized performance. In May, Costco’s net sales had surged 14.5% to $24.01 billion, with comparable sales reaching 12.5%, driven by strong U.S. comps of 13.7%. By June, U.S. comparable sales moderated to 10.6%, while Canada’s comparable sales slipped to 3.7% and other international regions grew 4.7%, according to Costco’s official sales report.
Digitally-enabled sales remained a bright spot. The company reported digitally-enabled comparable sales growth of 20.9% for the five-week period, far outpacing the overall comparable sales figure and underscoring the strength of Costco’s online channel. For the year-to-date 44-week period, digitally-enabled sales grew 21.5%, demonstrating sustained momentum in e-commerce.
Costco also announced a quarterly cash dividend of $1.47 per share, payable August 7, 2026, to shareholders of record on July 24. The company operates 933 warehouses globally, including 641 in the United States and Puerto Rico, as of the June reporting date.
