Summary
Costco reported strong fourth-quarter and full-year fiscal 2026 results. Net sales for the 16-week quarter rose 11.2% to $93.9 billion, driven by a 9.4% increase in comparable sales (6.7% adjusted for gasoline prices and foreign exchange). Net income climbed 14.9% to $2.998 billion, with diluted EPS up 15.0% to $6.75.
The quarter included a non-recurring $0.15 per share benefit from IEEPA tariff refunds; excluding that, net income and EPS grew 12.3% and 12.4%, respectively. For the full 52-week fiscal year, net sales increased 10.1% to $297.2 billion, and net income rose 13.9% to $9.226 billion, or $20.76 per diluted share.
Membership metrics remained healthy: worldwide renewal rate was 89.8%, total cardholders grew 3.6% to 150.4 million, and executive memberships reached 42.3 million. Costco ended the year with 939 warehouses and expects to reach 967 by the end of fiscal 2027. Retail investors should view these results as confirmation of Costco's continued top- and bottom-line momentum, with strong comparable sales and membership growth supporting the business. The IEEPA tariff refund benefit is a one-time item, but underlying growth remains solid.
