Have you ever walked into a Costco and felt the buzz of shoppers snagging deals on everything from giant cereal boxes to discounted TVs? There’s something uniquely satisfying about the experience—pushing a massive cart through aisles stacked high with value. But beyond the allure of bulk buys, Costco’s recent financial performance is turning heads, especially for investors. The retail giant’s fiscal third quarter of 2025 delivered results that not only beat Wall Street’s expectations but also sparked conversations about its resilience in a shifting economic landscape. Let’s dive into what these numbers mean, why they matter, and how Costco’s unique business model could make it a standout choice for your portfolio.
Costco’s Q3 2025: A Retail Powerhouse Shines
The numbers are in, and Costco is flexing its retail muscle. For the quarter ending May 11, 2025, the warehouse club reported a net income of $1.90 billion, translating to $4.28 per share. That’s a solid step up from last year’s $1.68 billion, or $3.78 per share. Revenue? A whopping $63.21 billion, up 8% from $58.52 billion in the same period last year. Analysts, according to LSEG, expected earnings of $4.24 per share and revenue just shy of $63.19 billion. Costco didn’t just meet expectations—it cleared them with room to spare.

What’s driving this success? For one, Costco’s membership model is a cash flow machine. Shoppers pay annual fees for access to those unbeatable prices, creating a loyal customer base and a steady revenue stream. But there’s more to the story. Economic uncertainty, particularly around tariffs, is reshaping consumer behavior—and Costco is positioned to capitalize. Let’s break it down.
Why Tariffs Could Be Costco’s Secret Weapon
Tariffs are the talk of the town, and they’re stirring up both concern and opportunity. As trade policies tighten, prices for everyday goods could climb, squeezing consumers’ wallets. But here’s where Costco shines. Its bulk discount strategy offers shoppers a way to stretch their dollars further. Imagine stocking up on a year’s worth of toilet paper or snagging a discounted flatscreen TV—Costco’s value proposition feels like a lifeline when prices elsewhere are creeping up.
In my experience, people flock to value during tough times. Costco’s CEO, Ron Vachris, echoed this sentiment earlier this year, noting that in uncertain economies, members lean harder on the retailer’s promise of high-quality goods at low prices. With about a third of Costco’s U.S. sales tied to imported goods—less than half of which come from China, Mexico, and Canada—the company isn’t overly exposed to any single market. This diversification could shield it from the worst of tariff-related disruptions.
- Competitive pricing: Costco’s scale allows it to negotiate better deals with suppliers.
- Member loyalty: Annual memberships drive repeat visits, even in downturns.
- Essential goods: Groceries and gas keep foot traffic steady, no matter the economy.
But it’s not all smooth sailing. Tariffs could raise Costco’s costs, potentially forcing price hikes. Other retailers, like Best Buy and Walmart, have already signaled increases. Yet, Costco’s size gives it leverage to absorb some of these costs, keeping prices lower than competitors. It’s a delicate balance, but one Costco has navigated before.
The Membership Model: Costco’s Golden Goose
Let’s talk about what makes Costco tick: its membership model. Unlike traditional retailers, Costco charges customers an annual fee—typically $60 or $120 for executive tiers—to shop its stores. This isn’t just a revenue stream; it’s a psychological hook. Once you’ve paid, you’re motivated to shop there to “get your money’s worth.” It’s a brilliant strategy, and it’s why Costco boasts renewal rates north of 90% in many markets.
The membership model creates a virtuous cycle: loyal customers, predictable revenue, and the ability to keep prices low.

This model also insulates Costco from economic swings. Even when consumers tighten their belts, they’re less likely to cancel a Costco membership because it’s seen as a gateway to savings. Plus, the retailer’s focus on essentials—think milk, eggs, and gas—ensures steady traffic. In Q3, these categories likely drove much of the 8% sales growth, as shoppers prioritized value over discretionary spending.
Here’s a quick breakdown of why the membership model works:
- Recurring revenue: Membership fees provide a stable cash flow, even in tough times.
- Customer retention: High renewal rates mean a loyal base that keeps coming back.
- Bargaining power: Costco’s size lets it negotiate better prices, passing savings to members.
Perhaps the most interesting aspect is how this model appeals to investors. Predictable revenue streams are catnip for Wall Street, and Costco’s ability to grow both membership and sales makes it a rare gem in retail.
How Costco Stacks Up Against the Market
Costco’s stock has been a quiet winner in 2025, climbing about 10% year-to-date as of late May. Compare that to the S&P 500, which has barely budged with less than 1% gains over the same period. Why the outperformance? Investors see Costco as a defensive stock—one that holds up when economic storm clouds gather. Its focus on essentials and value makes it less vulnerable to consumer pullbacks than, say, luxury retailers.
| Metric | Costco (Q3 2025) | S&P 500 (YTD 2025) |
| Revenue Growth | 8% | N/A |
| Earnings Per Share | $4.28 | N/A |
| Stock Performance | +10% | +1% |
This table tells a story of resilience. While the broader market treads water, Costco’s focus on value and efficiency keeps it ahead. But is it all rosy? Not quite. Rising costs from tariffs could eat into margins, and competition from Walmart and Amazon remains fierce. Still, Costco’s unique positioning gives it an edge.
Navigating Economic Uncertainty
Economic uncertainty is like a fog—hard to see through, but you can still navigate if you’ve got the right tools. For Costco, those tools are its global supply chain and strategic pricing. About a third of its U.S. sales come from imports, but its diversified sourcing—spanning Asia, North America, and beyond—reduces reliance on any single region. This flexibility could help Costco weather tariff-related cost increases better than smaller retailers.
But let’s be real: no company is immune to inflation or trade disruptions. If tariffs push up costs, Costco may have to raise prices, which could test customer loyalty. Yet, its track record suggests it can handle this. During past inflationary periods, Costco leaned on its private-label brand, Kirkland Signature, to offer affordable alternatives to name-brand goods. Expect more of that if costs climb.

Another factor? Costco’s gas stations. With fuel prices often lower than competitors, they’re a magnet for shoppers. Once members are in the parking lot, they’re likely to pop inside for groceries or that impulse-buy air fryer. It’s a subtle but powerful way to drive sales.
What’s Next for Costco Investors?
So, should you add Costco to your portfolio? It’s a question worth pondering. The company’s consistent growth and defensive qualities make it appealing, especially in uncertain times. Its stock isn’t cheap—trading at a premium due to its strong performance—but the stability and growth potential might justify the price.
Here’s a quick checklist for investors considering Costco:
- Strengths: Loyal customer base, strong brand, and diversified supply chain.
- Risks: Tariff-driven cost increases and competition from e-commerce giants.
- Opportunities: Expanding membership base and growing private-label sales.
In my view, Costco’s ability to thrive in good times and bad makes it a stock to watch. It’s not flashy like a tech startup, but its steady performance is hard to ignore. If tariffs push consumers toward value-driven retailers, Costco could see even more foot traffic—and revenue.
The Bigger Picture: Retail in a Changing World
Costco’s Q3 2025 results are more than just numbers—they’re a snapshot of a retail giant adapting to a complex world. Tariffs, inflation, and shifting consumer habits are reshaping the industry, but Costco’s value-driven model keeps it ahead of the curve. Whether it’s through bulk discounts, private-label goods, or discounted gas, the company knows how to keep customers coming back.
For investors, Costco offers a rare blend of growth and stability. It’s not immune to challenges, but its track record suggests it can handle whatever comes next. As economic uncertainty looms, the question isn’t whether Costco will survive—it’s how much stronger it’ll get.
In retail, adaptability is everything. Costco’s not just adapting—it’s thriving.
