Costco reports fiscal fourth-quarter 2026 results on September 24, and the number Wall Street actually cares about has nothing to do with comparable sales. It is the membership renewal rate, and it is holding near its best levels in the company’s history.
Why now matters. The stock has pulled back sharply from its 52-week high of $1,096.50 and trades near $895 today, roughly 18% lower. That is not a business deteriorating. It is a premium consumer business reset by a market that turned cautious on discretionary spending and supply chain costs all at once. The fundamentals beneath the surface have not moved in kind.
Costco’s membership engine is the whole company in a sentence. At the end of fiscal Q3 2026, the U.S. and Canada renewal rate was 92.2% and the worldwide rate was 89.7%, demonstrating the kind of loyalty that does not wobble much even after the company raised its premium fee to $130 effective September 1, 2024. Management said the fee increase accounted for approximately 25% of membership income growth in the third quarter and 35% over the first 36 weeks of fiscal 2026, while renewal rates remained near prior levels. That is a pricing test most consumer businesses would envy.
The financial architecture that results is unusual. Costco’s merchandise operation runs on razor-thin margins. Membership fees generated $2.684 billion in revenue across the first 24 weeks of fiscal 2026, and that fee stream did not exceed the company’s total operating income of $5.069 billion over the same span. Strip out membership fees and Costco’s operating income would be far thinner. Keep them, and you own one of the most durable profit models in retail.
What Wall Street expects September 24. Consensus is for $6.53 to $6.55 in adjusted EPS, up roughly 12% year over year, on revenue of approximately $94.85 billion, a 10% gain from the prior year. Costco has matched or beaten EPS estimates in five consecutive quarters. A UBS analyst, carrying a Buy rating and a $1,275 price target, published a research note this month describing the company’s sustainable business model as still fully intact despite a more complex retail backdrop.
The quieter catalyst is a potential special dividend. Analysts are discussing the possibility of a special payout following the September 24 report, though it remains unconfirmed. Costco paid a $15-per-share special dividend on January 12, 2024 and has a history of returning surplus cash this way when conditions are favorable. Wall Street projects free cash flow to expand from $7.8 billion in 2025 toward $12.25 billion by 2030, and the current payout ratio of 28% leaves ample room.
The risks deserve honest treatment. Oppenheimer’s Rupesh Parikh flagged that core earnings could come in below consensus once tariff refunds are stripped out of the results. Higher supply chain and fuel costs are also a margin headwind in Q4. The stock’s roughly 41x forward earnings multiple is not cheap by any historical standard. Costco has rarely been cheap. The question is whether that premium is earned by the durability of the membership model, and for more than 92% of members renewing every year in the U.S. and Canada, the answer is still yes.
Five days before the report, the case rewards investors who focus on the business rather than the headline earnings beat. A renewal rate above 92% in the U.S., a cash pile that could support a special dividend, and a stock about 18% below its high represent a more interesting combination than the number that will scroll across tickers next Thursday evening.
