COST Q2 2026 Earnings Analysis

Alex, these results really showcase why Costco remains such a powerhouse. Net income hit $2.04 billion, up 14% year-over-year, with earnings per share at $4.58 versus $4.02 last year. But what's even more impressive is the revenue growth - $68.2 billion in net sales, up 9.1% from the prior year.

Absolutely. Comp sales were up 7.4%, or 6.7% when you adjust for gas deflation and foreign exchange impacts. But here's what really caught my attention - digitally enabled comp sales surged 22.6%. That's a clear sign that Costco's digital transformation is gaining serious traction.

It really is. Membership fee income grew 13.6% to $1.36 billion. Now, about a third of that growth came from the September 2024 membership fee increase in the US and Canada. But even excluding that increase and foreign exchange impacts, membership income still grew 7.5% - that's solid organic growth driven by new members and executive membership upgrades.

That's actually an interesting strategic challenge they're navigating. The slight decline is primarily because online member sign-ups are growing as a percentage of their total base, and these digital members historically renew at slightly lower rates than those who sign up in-warehouse. But management is actively addressing this with targeted digital retention strategies, which are showing some positive impact.

Yes, and this is where Costco's operational expertise really shines. Vachris explained that they're dealing with a complex, fluid tariff environment where the old AIPA tariffs were eliminated but replaced with new global tariffs. Costco's response has been multi-pronged: shifting production countries when it makes sense, consolidating global buying efforts, leaning heavily into their Kirkland Signature private label where they control the supply chain, and sourcing more domestically.

Exactly. They actually lowered prices on key items like eggs, cheese, coffee, and paper products as commodity inflation cooled. And they're already reducing prices on items where tariffs have been eliminated - textiles, bedding, cookware. It's that member-first mentality that keeps customers loyal even in challenging times.

That's a significant acceleration from historical norms. What's particularly interesting is how they're getting creative with real estate. They mentioned projects like the Los Angeles location with residential units above the warehouse, and using parking decks to access dense urban markets they previously couldn't enter. They're applying lessons learned from their Asian and European operations to crack tough US metropolitan markets.

Absolutely. They're seeing meaningful improvements in checkout speed and employee productivity from mobile wallet enhancements and employee pre-scan technology. They're even piloting automated pay stations with eight-second transaction times. On the digital side, their personalized product recommendation carousels drove over $470 million in e-commerce sales in Q2 alone.

The gross margin story is really about operational excellence. Overall gross margins were up 17 basis points, though there was a 5 basis point boost from a one-time legal settlement. The core-on-core margins - which strip out mix effects - were up 22 basis points, showing broad-based improvement across food, non-food, and fresh categories. This improvement came even while they were lowering prices for members and managing tariff impacts.

International continues to outpace domestic growth. In February results, which they shared during the call, Canada was up 12.8% in comp sales, while other international was up 17.9%. China, Taiwan, and Korea were particular standouts. There was some discussion about China during Q&A, where management emphasized they're following their traditional playbook of entering carefully, learning the market, then accelerating growth.

The main risk factors they highlighted were ongoing Middle East tensions potentially impacting fuel costs and shipping schedules, and the continued evolution of the tariff environment. But management expressed confidence in their supply chain stability and inventory position. The membership renewal rate trend is worth monitoring, though their retention strategies appear to be working.

Costco continues to demonstrate the strength of its membership-based model. They're successfully navigating macroeconomic challenges while investing for long-term growth - whether that's warehouse expansion, digital capabilities, or supply chain efficiency. The 30+ warehouse annual opening target suggests they see significant runway for growth, and the digital acceleration opens up new possibilities for member engagement and retention. The key metrics - membership growth, renewal rates, comp sales, and margin expansion - all point to a business that's firing on multiple cylinders while staying true to its core value proposition for members.
