COST Q4 EPS jumps 15% to $6.75 on strong demand

COST Q4 EPS Jumps 15% to $6.75 as Costco Tops Estimates

Costco Wholesale ($COST) reported fiscal fourth-quarter earnings of $6.75 per diluted share for the 16-week period ended August 30, 2026, up 15% from a year earlier and ahead of expectations. The beat matters because it came even after backing out a 15-cent tariff-refund benefit, pointing to strong underlying demand and healthy membership momentum heading into the holiday season.

What Happened

Costco posted net income of $2.998 billion, or $6.75 a share, versus $2.610 billion, or $5.87 a share, in the same quarter last year. Net sales rose 11.2% to $93.9 billion from $84.4 billion, extending the company’s long-running pattern of steady top-line growth.

The quality of the print is what stood out. Management’s results included a 15-cent per-share benefit from tariff refunds, but the company still cleared consensus without relying entirely on that one-time tailwind. That suggests the core engine remained intact: traffic, basket strength, and a resilient value proposition that continues to draw shoppers despite a more cautious consumer backdrop.

Membership remained a key support pillar. Membership fee income rose 7.3% to $1.85 billion, while both worldwide and U.S./Canada renewal rates improved sequentially. For investors, that matters because Costco’s model depends on repeat visits, renewals, and the ability to convert traffic into steady fee income.

For the full fiscal year, Costco generated $297.2 billion in net sales, up 10.1% from $269.9 billion a year earlier. That keeps the warehouse club operator firmly in the top tier of U.S. retail growth names as the sector heads into the holiday quarter.

Analyst Take

Analysts viewed the print as evidence that Costco is still executing at a premium level. The earnings beat, combined with the improvement in renewal rates, helped push analysts to lift their price target on the stock.

The key takeaway for the Street is that Costco did not need a perfect macro environment to deliver. Even after stripping out the tariff-refund boost, earnings still beat expectations, underscoring durable demand from households that continue to prioritize value, convenience, and bulk purchasing.

That makes $COST an important read-through for retail sentiment overall. If Costco can keep growing sales, fees, and renewals at this pace, it reinforces the idea that higher-income and middle-income consumers are still spending selectively, especially at operators with clear savings propositions.

What to Watch

Holiday-quarter traffic trends, especially whether value-seeking shoppers continue to trade up to warehouse clubs.
Membership renewal rates, which remain one of the best indicators of Costco’s long-term moat.
Whether tariff-related benefits fade without disrupting margin durability.
How analysts revise estimates after the beat and whether higher targets translate into broader institutional buying.
Same-store sales and digital momentum, which will show whether Costco is gaining share beyond the core warehouse channel.

For traders, the message is straightforward: $COST delivered a cleaner-than-expected beat, and the durability of the membership model is still doing the heavy lifting. For long-only investors, the report keeps Costco on the shortlist of defensive growth names with real earnings power going into year-end.
