Costco Wholesale posted a record third quarter on Thursday, with net sales climbing 11.6% to $69.15 billion and profit rising 15% to $2.192 billion, or $4.93 per share. On the same night that American Eagle cratered on weak traffic, the warehouse giant reported comparable sales up 9.8% and a membership renewal rate near 90%. Read those two earnings reports side by side and you get the clearest picture of the American consumer right now: not collapsing, but splitting.
The Numbers Behind the Record
Costco’s quarter was strong almost everywhere it counts. Net sales rose to $69.15 billion from $61.96 billion a year earlier. Comparable sales, the metric that tracks existing-warehouse performance, grew 9.8%, and the digital side grew even faster, with digitally enabled comps up 21.5%. The full breakdown sits in the company’s third-quarter results filing, which also flagged record gasoline volumes as cheaper fuel pulled members into the parking lot and, from there, into the store.
A 9.8% comp from a retailer this size is the headline. Costco is not a scrappy upstart growing off a tiny base. It is one of the largest retailers on earth, and it is still compounding same-store sales at nearly double digits. That does not happen unless the model is taking share.
Follow the Money: The Membership Engine
Here is the part Wall Street actually cares about, and the part casual observers miss. Costco does not make most of its profit selling groceries and patio furniture. It makes it selling memberships. Membership fee income rose 10.7% in the quarter, and the renewal rate held at 89.7%, slightly ahead of expectations.
That is the whole business model in two numbers. The merchandise is sold at razor-thin margins to drive traffic; the profit comes from the high-margin, recurring, prepaid membership fee that members pay before they buy a single item. It is closer to a subscription business than a retailer, and a near-90% renewal rate is the kind of customer loyalty most subscription companies would trade their roadmap for. As long as renewals hold, Costco prints predictable, recurring profit regardless of what any single quarter’s merchandise margin looks like.
The Trade-Down Tailwind
Why is Costco winning while teen apparel is losing? The same macro pressure that hurts one helps the other. When budgets tighten, shoppers do not stop spending, they reallocate. They trade down to value, they bulk-buy to cut per-unit cost, and they consolidate trips to save on gas. Costco is the purest expression of that behavior, the same trade-down dynamic visible across discount retail, including the strength we noted in our look at Dollar Tree’s quarter.
This is the bullish read on a cautious consumer. People feeling squeezed are not vanishing from the economy, they are getting more deliberate about where the money goes, and the warehouse-club format is built precisely for the deliberate shopper. Cost-conscious is not the same as broke. Costco monetizes the difference.
Why the Stock Barely Moved
Despite the beat, shares rose less than 1% in extended trading, a muted reaction captured in the earnings-call coverage. That is not a knock on the quarter. It is a comment on the price. Costco trades at a premium multiple precisely because the market already assumes it will keep executing like this. When perfection is priced in, even a record quarter struggles to move the stock, because there is no upside surprise left to capture.
That sets up the real risk for shareholders, and it is not operational. Costco’s stores will almost certainly keep humming. The risk is valuation: a company this richly valued has to keep delivering flawless quarters just to hold its ground, and any stumble gets punished hard. The business is bulletproof. The multiple is not.
The Bigger Read
Put Costco and American Eagle in the same frame and the K-shaped consumer comes into focus. Discretionary, brand-driven spending at the young and price-sensitive end is softening, while value-driven, essentials-led spending at the warehouse end is accelerating. Both are real. Both are happening at once. The mistake is reading either one as the whole economy.
For investors, the signal is to stop asking whether the consumer is strong or weak and start asking where the consumer is spending. The money is not leaving the system, it is moving toward value, and Costco just reported one of the cleanest quarters you will see of a company sitting exactly where that money is going.
