Costco Stock Rises as Q4 Earnings Beat Puts Membership Growth in Focus

Costco stock moved higher on Friday as investors rewarded a fiscal fourth-quarter earnings beat that highlighted the warehouse retailer’s durable traffic, expanding membership income and strong digital momentum. The move stood out in a stock market still sensitive to Treasury-yield pressure and questions about how much consumers can keep spending while inflation remains elevated.

Shares of Costco were up about 2% in Friday trading near $915, giving the company a market value above $400 billion. The advance came after the company reported net income of $2.998 billion, or $6.75 per diluted share, for the 16-week quarter ended August 30, up from $2.610 billion, or $5.87 per diluted share, a year earlier.

The headline profit included a non-recurring benefit of $0.15 per share tied to tariff refunds, but even allowing for that item, the quarter showed solid operating leverage. Net sales rose 11.2% to $93.9 billion, while total revenue, including membership fees, reached $95.7 billion. For the full fiscal year, net sales increased 10.1% to $297.2 billion and net income rose to $9.226 billion.

Membership fees reinforce Costco’s defensive stock appeal

The report gave investors a fresh reason to focus on Costco’s membership engine. Quarterly membership fees rose to $1.85 billion from $1.72 billion a year earlier, while full-year membership fees climbed to $5.91 billion. That recurring revenue stream remains central to the market’s willingness to assign Costco a premium valuation compared with many other consumer and retail stocks.

Comparable sales increased 9.4% in the fourth quarter, or 6.7% after excluding the impact of gasoline prices and foreign exchange. U.S. comparable sales rose 10.7%, or 7.2% on the adjusted basis, indicating that Costco continued to capture wallet share from shoppers seeking value on groceries, household staples and discretionary items purchased in bulk.

Digital sales also strengthened. Digitally enabled comparable sales rose 19.5% in the quarter and 20.9% for the full year, signaling that Costco is adding online scale without abandoning the warehouse model that drives repeat visits and membership loyalty. That mix is important for investors because it suggests the company can grow beyond new club openings while still protecting its low-price brand identity.

Valuation remains the key test after the earnings pop

The stronger earnings print does not remove the main debate around Costco stock: valuation. With the shares trading at a high earnings multiple, the market is already pricing in continued membership growth, steady renewal behavior and resilient consumer demand. That leaves less room for disappointment if traffic slows or operating costs rise faster than sales.

Still, Friday’s stock reaction suggests investors are treating Costco as a quality defensive growth name at a time when broader equity sentiment is being pulled between solid corporate earnings and higher bond yields. The company’s cash position, membership income and international store base give it more flexibility than many retailers facing a more uneven consumer backdrop.

Costco ended the fiscal year operating 939 warehouses across the United States, Canada, Mexico, Japan, the United Kingdom, Korea, Australia, Taiwan, China and several European markets. Continued unit expansion, combined with digital growth and higher membership revenue, gives the stock a clear earnings-growth path, though the premium share price means execution will need to remain strong into fiscal 2027.

For the stock market, the message from Costco’s results is straightforward: investors are still willing to pay for companies that can show recurring revenue, pricing relevance and consistent traffic. In a market where rate expectations can quickly pressure high-multiple stocks, Costco’s earnings beat gives bulls fresh support, but it also raises the bar for the next sales update.
