The Thesis
Summary
Walmart is a mature discount retailer that earns money by selling groceries and general goods through its 10,500 stores and growing online marketplace. It generated $713.16 billion in revenue last year, making it the largest company in the world by sales. While the core business is low-margin retail, the company is now rapidly expanding into higher-profit services like digital advertising and subscription memberships.
The core bet on Walmart is that high-margin services like advertising and membership income grow fast enough to lift the overall profit profile of the business. Walmart already has the customers and the data: it is now focused on selling that access to brands and charging shoppers for convenience. If these digital units keep outgrowing the physical stores, the business becomes more profitable even if retail sales stay steady. More specifically, four things need to be true:
We lean toward a cautious view because while the business is executing well, the current price of $115.75 significantly exceeds our $86 fair value estimate. The market is paying a premium for the shift to digital that leaves very little room for any growth slowdown.
Numbers at a Glance
What does it do?
Walmart is a mature business that earns money by selling a vast array of physical goods at thin markups across a global network of stores and websites. The company buys products in massive quantities from suppliers to keep prices lower than its competitors. It generates most of its revenue from the "Walmart U.S." segment, but it also operates "Walmart International" and "Sam's Club," a membership-only warehouse chain. Beyond selling goods, Walmart increasingly collects fees from advertisers who want to reach its shoppers and from consumers who pay for the Walmart+ subscription service.
Where does revenue come from?
Walmart generates the majority of its sales through physical retail, though digital channels are growing much faster. Revenue is split between Walmart U.S. (supercenters and discount stores), Walmart International (operations in Mexico, Canada, and China), and Sam's Club (bulk warehouse sales). The company also has a burgeoning services line including Walmart Connect, which sells digital ad space on its website, and membership fees from Sam's Club and Walmart+.
Revenue Breakdown
Revenue by Geography
Who are its customers?
Walmart serves hundreds of millions of shoppers globally, with over 10,500 stores and a digital marketplace that reached 27% growth in the most recent quarter. While historically known for serving lower-to-middle income households, the company is increasingly attracting higher-income shoppers who use its pickup and delivery services. Membership is a major focus, with membership income growing 22% in the latest reported period. Sam's Club contributes a significant base of recurring business through its warehouse model.
What gives it staying power?
Walmart's staying power comes from its massive scale, which creates a cost advantage that competitors cannot easily match. By buying more products than anyone else, it keeps its own costs low and passes those savings to customers. This scale also powers its growing advertising and fulfillment businesses.
Where is it headed?
The single biggest strategic bet Walmart is making is the transformation of its supply chain into an automated, high-speed delivery engine. Management is investing heavily in automated fulfillment centers to reduce the cost of shipping online orders. If successful, this lowers the expense of e-commerce while simultaneously making the company's advertising business more attractive to third-party sellers.
The revenue trend is one of steady, single-digit growth that hides a massive shift toward digital sales. Total revenue reached $713.16 billion last year, and while the total grew 4.7%, e-commerce sales jumped 27% in the most recent quarter. This shift shows that Walmart is successfully moving its massive customer base from physical aisles to digital carts.
Walmart generates significant cash, with free cash flow reaching $14.92 billion last year. While capital spending on store automation and technology is high, the business generates enough cash to fund these investments while still paying dividends. The gap between net income and free cash flow is primarily due to the heavy investments required to modernize its supply chain.
The balance sheet is strong and resilient, carrying a debt-to-equity ratio of 0.79x. With over $700 billion in annual revenue, the company can comfortably handle its debt while maintaining its dividend and share buyback programs. This financial strength allows Walmart to keep investing in expensive automation projects while smaller retailers are forced to cut costs.
Walmart is a financial powerhouse that is successfully using its massive retail cash flow to build a higher-margin digital business.
The digital services business is growing much faster than the core retail segment, with advertising revenue up 28% and membership income up 22%. These high-margin dollars are critical because they help offset the higher costs of shipping groceries to people's homes. This proves that Walmart's data on its shoppers is becoming a valuable product in its own right.
Consumer spending on discretionary goods like electronics and clothing remains a headwind compared to grocery sales. While people are still buying food, a sustained pullback in higher-margin "general merchandise" would put pressure on overall profit margins. Management is trying to fix this by improving its online marketplace, but the mix of what people buy still favors lower-profit groceries.
The global retail market is a multitrillion-dollar industry growing at roughly 3% annually, on track to reach $30 trillion by 2028. Structural pricing power is almost non-existent because shoppers can easily compare prices online, making scale the only way to survive. Walmart is the undisputed leader in this space, using its size to dictate terms to suppliers and maintain its position as the lowest-cost provider of essential goods for millions of households.
The retail market is brutally competitive, defined by thin margins and a constant battle for customer traffic. Barriers to entry for a new store are low, but the barriers to achieving Walmart's level of scale and logistics efficiency are nearly insurmountable. This forces the industry into a rational but intense struggle over every dollar of grocery share.
Amazon(AMZN) is the primary threat, using its digital dominance and Prime delivery speed to pull general merchandise spending away from physical stores. Target(TGT) competes by offering a more upscale, curated shopping experience that appeals to a slightly wealthier customer. Costco(COST) uses a membership model that locks in volume, while discounters like Aldi attack Walmart's core price-sensitive grocery shoppers with a simpler, lower-cost store model. Amazon remains the most dangerous threat because its digital scale allows it to lose money on retail while winning on cloud and ads.
Walmart is holding its ground and gaining share in grocery, largely due to its massive pickup and delivery network. Evidence of this strength is the 27% growth in e-commerce last quarter. Walmart is successfully defending its territory by becoming more like a tech company.
The primary source of protection is a massive cost advantage driven by unmatched scale in purchasing and logistics. Because Walmart buys in larger quantities than any other retailer, it pays less per unit, allowing it to underprice competitors while still remaining profitable. This scale is supported by 10,500 locations that act as both stores and mini-warehouses for online delivery.
The 11.9% ROIC and 25% gross margins prove that Walmart can extract value even in a commodity business. While these numbers aren't as high as software companies, they are remarkably durable and consistent across decades of retail cycles. This proves the moat is a structural advantage, not just a result of a good economy.
The moat is strengthening as Walmart integrates its physical scale with digital services like advertising and membership. The single most important signal is the 28% growth in advertising, which proves Walmart can monetize its scale in ways competitors cannot easily replicate.
Revenue grew from $611B to $713B in three years with steady margins.

Top executives have significant equity holdings; McMillon holds over $200M in stock.
Capital Allocation Track Record
Management has proven they can steer the world's largest company through a massive digital pivot without breaking the core retail engine. They are making the right long-term bets by spending on automation and high-margin services like advertising, rather than just chasing short-term sales. The team has shown exceptional discipline by generating record revenue while simultaneously improving the business mix toward more profitable digital channels.
