Costco Q2 2026 earnings (fiscal Q4) results were reported on September 24th after the market closed, with net sales increasing 11.2% to $93.9B and U.S. comparable store sales up 7.2% excluding gas and foreign exchange. Results were largely in line with expectations, and management sounded confident heading into the holiday season, pointing to strong non-food momentum in Q2, a compelling holiday assortment, and members’ continued willingness to spend when they see quality and value. Costco also reinforced its commitment to reinvesting tariff refunds into member value, while maintaining a cautious but steady outlook on inflation and consumer demand.
Overall, the quarter offered few surprises for investors and reinforced Costco’s position as a steady operator amid broader retail and consumer uncertainty, with minimal movement in the stock following the release.
*Note: Costco’s fiscal year runs from September to August, making their fiscal Q4 which ended August 30, 2026, comparable to other retailers’ Q2 2026 results.
