Costco Wholesale is the leading global membership warehouse retailer that operates 931 warehouses worldwide, and the question for the next twelve months is whether the company can convert the $69.15 billion Q3 FY2026 net sales up 11.6% year over year, the $203.37 billion first 36 weeks of FY2026 net sales up 9.6% year over year, the 9.8% Q3 FY2026 total company comparable sales growth, the 9.4% Q3 FY2026 U.S. comparable sales growth, the 10.7% Q3 FY2026 Canada comparable sales growth, the 11.2% Q3 FY2026 Other International comparable sales growth, the 21.5% Q3 FY2026 digitally enabled comparable sales growth, the $2.19 billion Q3 FY2026 net income, the $4.93 Q3 FY2026 diluted EPS up 15.2% year over year, the 931 warehouses including 639 in the United States and Puerto Rico, the 115 in Canada, the 43 in Mexico, the 37 in Japan, the 29 in the United Kingdom, the 20 in Korea, the 15 in Australia, the 14 in Taiwan, the 7 in China, the 5 in Spain, the 3 in France, the 2 in Sweden, the 1 each in Iceland and New Zealand, and the e-commerce sites in the U.S., Canada, the U.K., Mexico, Korea, Taiwan, Japan, Australia, and China into the kind of comp-sales-acceleration and member-economic operating leverage the company has been telegraphing. The Q3 FY2026 print was the cleanest test of that thesis, and the cleanest signal is that Costco Wholesale Corporation announced operating results for the third quarter and year-to-date for fiscal 2026 ended May 10, 2026 with net sales for the quarter increasing 11.6 percent to $69.15 billion and net sales for the first 36 weeks increasing 9.6 percent to $203.37 billion. The strategic tension is the 11.6% Q3 FY2026 net sales growth against the 9.8% Q3 FY2026 total company comparable sales growth, and the forward question is whether the comp-sales acceleration can compound the global warehouse expansion into the comp-sales-growth and EPS-growth the company has been telegraphing.
The $69.15 billion Q3 FY2026 net sales and the 11.6% year-over-year growth are the cleanest read on the operating momentum, and the 9.8% total company comparable sales growth is the proof. The Q3 FY2026 net sales of $69.15 billion grew 11.6% above the prior-year quarter's $61.97 billion. The first 36 weeks of FY2026 net sales of $203.37 billion grew 9.6% above the prior-year period's $185.48 billion. The Q3 FY2026 total company comparable sales grew 9.8% on a 12-week basis and 7.9% on a 36-week basis.
The Q3 FY2026 U.S. comparable sales grew 9.4% on a 12-week basis and 7.1% on a 36-week basis, the Q3 FY2026 Canada comparable sales grew 10.7% on a 12-week basis and 9.1% on a 36-week basis, the Q3 FY2026 Other International comparable sales grew 11.2% on a 12-week basis and 11.0% on a 36-week basis, the Q3 FY2026 adjusted U.S. comparable sales grew 6.8% on a 12-week basis and 6.4% on a 36-week basis excluding the impacts from changes in gasoline prices and foreign exchange, the Q3 FY2026 adjusted Canada comparable sales grew 6.2% on a 12-week basis and 7.6% on a 36-week basis, the Q3 FY2026 adjusted Other International comparable sales grew 5.9% on a 12-week basis and 6.6% on a 36-week basis, the Q3 FY2026 adjusted total company comparable sales grew 6.6% on a 12-week basis and 6.6% on a 36-week basis, the Q3 FY2026 Digitally-Enabled comparable sales grew 21.5% on a 12-week basis and 21.6% on a 36-week basis, the Q3 FY2026 adjusted Digitally-Enabled comparable sales grew 20.8% on a 12-week basis and 21.1% on a 36-week basis, the Q3 FY2026 net income of $2.19 billion or $4.93 per diluted share compared to the prior-year quarter's $1.90 billion or $4.28 per diluted share, the first 36 weeks of FY2026 net income of $6.23 billion or $14.01 per diluted share compared to the prior-year period's $5.49 billion or $12.34 per diluted share, the 931 warehouses including 639 in the United States and Puerto Rico, the 115 in Canada, the 43 in Mexico, the 37 in Japan, the 29 in the United Kingdom, the 20 in Korea, the 15 in Australia, the 14 in Taiwan, the 7 in China, the 5 in Spain, the 3 in France, the 2 in Sweden, the 1 each in Iceland and New Zealand, the e-commerce sites in the U.S., Canada, the U.K., Mexico, Korea, Taiwan, Japan, Australia, and China anchor the print. The forward question is whether the comp-sales acceleration can compound the global warehouse expansion into the comp-sales-growth and EPS-growth.
