Costco’s Real Moat Is Becoming More Valuable as Consumers Get Poorer

I can tell when a grocery bill has changed my mood. I start comparing unit prices with the intensity of a forensic accountant. I decide that every errand should happen on the same trip because gasoline has apparently become a luxury purchase. Then I walk into Costco for coffee and detergent and leave wondering whether I have enough room at home for forty-eight rolls of paper towels.

That last part is funny until I look at Costco’s latest quarter. The company is benefiting from the same pressure that has households planning their shopping more carefully. Its fourth-quarter revenue rose about 11% to $95.72 billion, ahead of the $94.86 billion analysts expected. Comparable sales, excluding gasoline and currency effects, increased 6.7%, beating the 6.11% estimate. Costco also reported adjusted earnings of $6.60 a share after removing a one-time, 15-cent benefit from tariff refunds, compared with expectations of $6.53. Reuters

Those numbers tell me Costco had a strong quarter. The more interesting question is why it had one—and whether I should pay today’s stock price for the answer.

The membership starts to feel more valuable when money feels tighter

Costco’s proposition is familiar: pay an annual fee, get access to low prices across a deliberately limited selection of goods, and buy enough of them to make the trip worthwhile. The company says its high volumes, rapid inventory turnover, and efficient distribution let it operate with lower merchandise margins. That structure matters more to me than any single eye-catching bargain in the warehouse. Investor Relations

When prices rise, a member has another reason to make the fee earn its keep. A household that already belongs may move more purchases to Costco. A fuel stop can turn into a grocery run. A grocery run can become the place to buy household essentials as well. The savings need to be real for the individual shopper, of course; buying a giant package that goes to waste is an expensive way to feel thrifty. But when the arithmetic works, Costco has a chance to capture a larger share of that household’s spending.

Reuters reported that shoppers are increasing their average basket sizes as they consolidate trips. CEO Ron Vachris described gasoline as having a record year, while discounted fuel helped draw price-conscious customers. I read those details as evidence that Costco is benefiting from both sides of a costly drive: customers have a reason to visit its pumps and an incentive to accomplish more while they are there.

I would be careful, though, about calling every dollar of extra spending a permanent gain. Bigger baskets might reflect stronger loyalty. They might also reflect fewer, more heavily stocked trips by people trying to conserve time and fuel. The quarter shows that Costco captured the spending; it cannot, by itself, tell me how much of this particular shopping pattern will last if household pressures ease.

The tariff refunds are useful, but I’m taking them out of my earnings picture

Costco received $184 million in tariff refunds during the quarter. Management said it reinvested some of that money through lower prices on items including meat, beverages, essentials, and selected nonfood merchandise. I like that choice. Lower prices give members another reason to keep shopping, which fits the company’s long-term model. Reuters

As an investor, I still need to separate that event from repeatable earnings. The adjusted $6.60 per share already excludes the 15-cent benefit identified in the report. A refund can help Costco sharpen prices and reinforce its value reputation, but I cannot build a normal annual profit forecast by assuming it receives the same windfall every quarter.

The gasoline story needs similar care. Discounted fuel can make a membership feel indispensable and bring shoppers onto the property. It does not follow that each fuel sale is as profitable as each membership fee or every item that lands in a cart. If I were evaluating the next few quarters, I would watch whether strong fuel traffic continues to translate into healthy warehouse sales after excluding the direct effect of fuel prices. This quarter’s 6.7% adjusted comparable-sales growth suggests the underlying stores are doing well; I want to see that strength persist.

A wonderful business can still be an expensive stock

Here is where my enthusiasm meets the share price. At roughly $921 during Friday afternoon trading, Costco was selling for about 46 times trailing earnings. That is a substantial expectation to attach to a retailer, however well run. The company can keep gaining share and growing profits while the stock delivers a disappointing return if investors eventually decide to pay a lower multiple for those profits.

I see a real moat in the combination of membership habits, purchasing scale, low prices, and shopping convenience. I also see a market that knows about it. The latest quarter strengthened my confidence in Costco’s operations. It did less to convince me that the shares are a bargain.

My view on COST is Hold at this price. I would be more interested in adding shares after a meaningful pullback, or after earnings growth brings the valuation down without requiring the share price to fall. That is a judgment about what I am willing to pay, not a prediction that Costco’s business is about to weaken.

The risk to my caution is straightforward: Costco could keep growing strongly enough that today’s premium looks reasonable in hindsight. The risk to a new buyer is just as straightforward: current enthusiasm leaves little room for a period of slower growth. I would watch adjusted comparable sales, membership trends, and the pace of earnings growth more closely than the next headline about a crowded gas station.

What this quarter really says

I think Costco has become especially useful to customers who are tired of making their budgets stretch. Its latest results support that view. Households are consolidating trips, buying more per visit, and showing up for discounted fuel. Costco is responding with low prices while its core sales continue to grow faster than analysts expected. Reuters

I would stop short of saying consumers are literally getting poorer based on one earnings report. The sharper point behind that headline is that many shoppers feel more constrained, and Costco is built to make its membership feel valuable under those conditions. Its moat may be growing more useful at the exact moment customers are paying closer attention to what they spend.

If I owned the stock, this quarter would give me a reason to keep holding it. If I were buying it for the first time, I would want a better price. Costco has earned my respect as a business. At about 46 times trailing earnings, its shares are asking me to pay for plenty of that respect in advance.
