Costco Wholesale (NASDAQ: COST) reported fiscal fourth-quarter earnings of $6.75 per share on September 24, beating the $6.54 analyst consensus, as net income reached $2.998 billion for the 16 weeks ended August 30. Net sales grew 11.2 percent year over year, and the warehouse club reinvested $184 million in tariff refunds into lower member prices.
The setup
Heading into the report, Oppenheimer analyst Rupesh Parikh had warned that consensus estimates were a best-case scenario unless management delivered on expense controls and kept excess fuel profits from being reinvested. Costco cleared the bar anyway, helped by a $0.15 per share benefit from tariff refunds.
Total revenue came in just shy of the $94.97 billion Wall Street expected. Investors looked past the rounding miss and focused on what actually drives the business: membership.
Management said renewal rates improved and executive membership kept growing. Because membership fees anchor most of Costco’s profit, those two numbers matter more than any single quarter of merchandise margin.
Key numbers
| Metric | Result |
|---|---|
| Diluted EPS | $6.75 vs. $6.54 expected |
| Net income | $2.998 billion vs. $2.610 billion a year earlier |
| Net sales growth | +11.2 percent year over year |
| Comparable sales | +9.4 percent overall, +10.7 percent U.S. |
| Digital sales growth | +19.5 percent |
| Tariff refunds received | $184 million, reinvested into prices |
| Price-to-earnings ratio | Approximately 32 times |
The tariff refund story deserves attention. Costco collected $184 million of refunds and interest in the quarter and pushed the cash directly into price cuts, with a similar amount already received in the first quarter of fiscal 2027. The move trades short-term margin for member loyalty, which fits the company’s long-standing playbook.
What to watch
- Core margins as refunds fade: The $0.15 per share benefit is not permanent, so underlying profitability deserves scrutiny next quarter.
- Renewal rate trajectory: Improving renewals suggest recent fee increases stuck without alienating members.
- Valuation: At roughly 32 times earnings, the stock prices in continued execution with little room for stumbles.
- Consumer demand: Comparable sales near 10 percent show spending holding up, but any pullback would test the premium multiple.
The year-over-year comparison shows the quality of the growth. Net income climbed to $2.998 billion from $2.610 billion, and diluted earnings per share rose 15 percent, from $5.87 to $6.75, on comparable 16-week quarters.
The initial market reaction was muted, and some analysts trimmed price targets even after the beat. That response signals the bar for this stock now sits at flawless execution rather than headline growth.
Bottom line
Costco closed fiscal 2026 with an earnings beat, double-digit sales growth, and a membership base that keeps paying up. Pushing tariff windfalls into lower prices shows management playing the long game rather than managing quarterly optics.
Income investors should note the dividend remains modest relative to the share price. The appeal here is durable compounding, not current yield. Costco shares recently traded near $915, and the stock’s dividend yield sits below 1 percent, which places it firmly in the growth camp rather than the income camp.
