Have you ever walked into a Costco and felt that buzz of excitement, like you’re on a treasure hunt for the best deals? I sure have. There’s something about those towering aisles and unexpected finds that keeps shoppers coming back. In its fiscal fourth quarter of 2025, Costco didn’t just meet expectations—it crushed them, posting earnings and revenue that left analysts impressed. What’s behind this retail giant’s success? Spoiler alert: it’s not just about bulk toilet paper and cheap hot dogs. Costco’s ability to attract younger shoppers, boost its online presence, and navigate economic challenges like tariffs is reshaping how we think about warehouse retail.
The Secret Sauce of Costco’s Q4 Success
Costco’s recent performance isn’t just a win for the company—it’s a masterclass in adapting to changing consumer habits. The retailer reported earnings per share of $5.87, beating Wall Street’s estimate of $5.80, and raked in $86.16 billion in revenue, slightly above the expected $86.06 billion. Net income climbed to $2.61 billion, up from $2.35 billion a year ago. These numbers tell a story of a company firing on all cylinders, but the real magic lies in how Costco is evolving to stay relevant.
Let’s break it down. Costco’s not just surviving in a competitive retail landscape—it’s thriving. From my perspective, it’s their knack for balancing tradition with innovation that sets them apart. They’ve kept the core of what makes Costco, well, Costco—think massive savings and that iconic $1.50 hot dog combo—while embracing trends that appeal to a new generation of shoppers.
Winning Over Younger Shoppers
One of the most intriguing aspects of Costco’s recent success is its growing appeal to younger consumers. I’ve always thought of Costco as a place for families stocking up on groceries, but it turns out millennials and Gen Z are getting in on the action. According to company insights, nearly half of Costco’s new members each year are under 40, and the average age of its membership base is trending younger.

So, what’s pulling in the under-40 crowd? For one, Costco’s stepped up its merchandise game. From trendy apparel to high-end electronics, the retailer’s treasure hunt shopping experience keeps things fresh. You never know if you’ll stumble across a designer jacket or the latest smart home gadget. Plus, Costco’s focus on affordable meals—like that legendary hot dog and soda combo—resonates with budget-conscious younger shoppers navigating inflation.
But it’s not just about what’s on the shelves. Costco’s making shopping more convenient, with options like curbside pickup and a slicker online platform. These changes cater to younger consumers who value flexibility and speed, whether they’re browsing in-store or online.
E-Commerce: The Digital Leap Forward
Speaking of online, Costco’s e-commerce growth is nothing short of impressive. In Q4 2025, e-commerce sales surged by 13.5% compared to the previous year, even when you strip out the effects of gas prices and currency fluctuations. That’s a big deal for a company known for its massive warehouses. I’ve always believed that retailers who nail the online experience while keeping their physical stores vibrant have a winning formula, and Costco’s proving it.
The company’s digital strategy isn’t about replacing the in-store experience—it’s about enhancing it. From my vantage point, Costco’s online platform feels like an extension of the warehouse, offering everything from bulk groceries to exclusive deals on big-ticket items. This seamless blend of physical and digital shopping is a key reason why younger consumers are signing up.
- Improved website usability: Easier navigation and faster checkout processes.
- Exclusive online deals: Unique offerings that complement in-store treasures.
- Curbside pickup options: Convenience for busy shoppers who want to skip the aisles.
This digital push isn’t just about keeping up with competitors—it’s about setting the pace. Costco’s investment in its online platform shows it’s serious about capturing the growing number of shoppers who prefer to browse from their couches.
Navigating Economic Headwinds
Let’s talk about the elephant in the room: economic uncertainty. With tariffs looming as a potential challenge for retailers, Costco’s shown it’s got a plan. Unlike some competitors who might get caught flat-footed, Costco’s leadership has been proactive. They’ve rerouted imports, rushed orders to beat tariff deadlines, and leaned into their private-label brand to source goods from regions less affected by duties.
Costco’s agility in managing tariff-related costs is a testament to its operational strength.

Why does this matter? Because tariffs can drive up prices, and nobody likes paying more for their groceries. Costco’s focus on groceries, which make up the bulk of its sales, gives it a buffer. Shoppers don’t just go to Costco for deals on TVs—they’re there for essentials like food and household goods, which are less likely to be hit hard by trade policies. Add in the treasure hunt model, where Costco swaps out merchandise regularly, and you’ve got a retailer that’s nimble enough to dodge economic curveballs.
Same-Store Sales: A Mixed Bag
Not everything’s rosy, though. Costco’s same-store sales grew by 6.4% in Q4, excluding gas and currency impacts, but that’s a slowdown from previous quarters. For context, same-store sales measure performance at existing locations, ignoring the impact of new store openings or closures. A 6.4% increase is solid, but the deceleration has some analysts raising eyebrows.
Does this mean Costco’s losing steam? I don’t think so. Retail is cyclical, and a slight dip in same-store sales growth doesn’t erase the bigger picture. Costco’s still opening new locations and attracting more members, which suggests the slowdown might just be a blip. Still, it’s worth keeping an eye on how this metric evolves in the coming quarters.
| Metric | Q4 2025 | Analyst Expectation |
| Earnings Per Share | $5.87 | $5.80 |
| Revenue | $86.16B | $86.06B |
| Same-Store Sales Growth | 6.4% | N/A |
| E-Commerce Sales Growth | 13.5% | N/A |
Why Costco’s Stock Is Still a Hot Topic
Costco’s stock has been a darling of investors, soaring by roughly 180% over the past five years. That’s the kind of growth that makes you wish you’d bought shares back when you first grabbed a membership card. But here’s the catch: in 2025, Costco’s stock has lagged behind the broader market, with a modest 2% gain compared to the S&P 500’s 12% rise. So, what gives?
In my view, this underperformance is more about market dynamics than Costco’s fundamentals. The company’s still delivering strong results, expanding its footprint, and winning over new customers. Investors might be taking a breather after years of stellar gains, but Costco’s long-term potential remains robust. After all, a retailer that can attract younger shoppers, grow its digital sales, and navigate tariffs isn’t one to underestimate.
What’s Next for Costco?
Looking ahead, Costco’s in a strong position to keep its momentum going. The retailer’s ability to blend value, variety, and convenience makes it a standout in a crowded market. But there are questions worth pondering. Can Costco sustain its e-commerce growth? Will younger shoppers continue to drive membership numbers? And how will the company handle potential economic challenges like inflation or higher tariffs?
Personally, I’m optimistic. Costco’s track record shows it’s not afraid to adapt, whether that means tweaking its supply chain or rolling out new digital features. The company’s focus on keeping costs low and customers happy is a formula that’s hard to beat.
Costco’s not just a retailer—it’s a lifestyle brand that resonates across generations.

Maybe that’s the real takeaway. Costco isn’t just selling bulk goods—it’s selling an experience. Whether you’re a millennial hunting for a deal on organic snacks or a retiree stocking up on household essentials, Costco’s got something for everyone. And in Q4 2025, it proved it’s still got plenty of tricks up its sleeve.
