What happened
Costco (COST) stock rose 2.9% on Friday after the retailer reported Q4 FY2026 earnings of $6.75 per share, beating the $6.54 consensus on 9.4% comparable-sales growth. Total revenue for the 16-week quarter came in at $95.72 billion, up 11.2% from a year ago and above Wall Street's $94.97 billion estimate. Analysts noted that $0.15 of the $0.21 per-share beat came from one-time IEEPA tariff refunds — government rebates on import duties — making the underlying beat roughly $0.06 per share. Costco passed about half of the $184 million in refunds to members as lower prices on staples and produce, and plans 33 new warehouse openings in FY2027.
Why it matters
Costco stock trades at roughly 40 times next year's expected earnings — one of the richest valuations in retail — so the quality of each beat matters as much as the size. The $0.15-per-share IEEPA tariff refund was a one-time government rebate that will not repeat in FY2027, leaving investors to judge whether the core business can grow fast enough to fill that gap. With paid membership at a record 84.1 million and 33 new warehouses planned, Costco is betting heavily on scale to justify that premium.
