Walmart runs more than 10,900 stores across 19 countries and serves roughly 280 million customers every week. The core business is simple: buy enormous volumes of groceries, household goods, electronics, and clothing from suppliers, then sell them in stores and online at prices low enough that shoppers keep coming back. Most of the money comes from those product sales — $706.4 billion in net sales in fiscal 2026. But Walmart is also building newer revenue streams on top of that foundation: Walmart+ memberships, a fast-growing digital advertising business, a third-party marketplace where other sellers list products, and fulfillment services that ship those products. Each of these layers earns a higher profit margin than selling a box of cereal, and together they are quietly changing what kind of company Walmart is becoming. The diagram below traces where the money goes.
Five years of financial data tell a clear story: Walmart is getting bigger every year without sacrificing profitability. Revenue climbed from $567.8 billion in fiscal 2022 to $706.4 billion in fiscal 2026 — an increase of nearly $139 billion over four years. That is not the growth rate of a scrappy startup, but for a company already this large, consistent mid-single-digit annual growth is genuinely hard to achieve. The gross margin — the slice of each dollar left after paying for the goods sold — dipped slightly in 2023 before recovering. By fiscal 2026 it sat at 24.2%, roughly where it was in 2022, which means Walmart has managed its costs and pricing even as inflation rattled supply chains.
Cash generation has improved meaningfully. Operating cash flow — the cash the business actually produces before capital spending — rose from $24.2 billion in fiscal 2022 to $41.6 billion in fiscal 2026. That matters because Walmart is spending heavily to build out automation, eCommerce fulfillment centers, and store remodels. Capital expenditures reached $26.6 billion in fiscal 2026 alone. Even after all that spending, the company generated $14.9 billion in free cash flow — the cash left over after paying for those investments.
Net debt — what Walmart owes lenders minus the cash it holds — has stayed in a manageable range. It was $23.3 billion in fiscal 2022 and $34.0 billion in fiscal 2026. That modest rise reflects deliberate borrowing to fund growth, not financial distress. For a company generating over $40 billion in operating cash annually, a $34 billion debt load is not alarming. Return on assets climbed from prior years to 8.2% in fiscal 2026, and return on investment was 15.1% — both pointing in the right direction even as the company ploughs billions into its future.
The strategic shift Walmart is making is visible in the numbers. The Walmart U.S. segment — its biggest, covering 4,611 stores — reported gross profit at 27.5% of sales in fiscal 2026, up from 26.8% two years earlier. The company specifically credits growth in advertising and membership (Walmart+ showed double-digit membership revenue growth) for pulling the margin higher. Sam's Club U.S., the membership warehouse chain with 601 locations, is also leaning into this model: membership income is a significant part of its operating income, and its membership base grew meaningfully in both fiscal 2025 and 2026.
Walmart faces real, specific risks — not just the generic 'competition is tough' disclaimers found in most annual reports. The company is spending heavily on artificial intelligence and automation. If those investments do not produce the expected efficiency gains, or if customers do not use the new digital tools as planned, the capital deployed may not earn an adequate return. Supply chains are a second pressure point: less than a third of what Walmart sells in the U.S. is imported, but those imports come primarily from China, Mexico, Vietnam, India, and Canada — all subject to shifting tariff rules and trade restrictions that Walmart itself flags as a source of continued uncertainty.
The pharmacy business inside Walmart stores is another specific vulnerability. That operation earns most of its money by filling prescriptions and collecting reimbursements from insurance companies and government health programs. If those payers reduce what they pay Walmart — a trend that has hit pharmacy chains broadly — pharmacy profits could fall materially. Then there is the marketplace: Walmart allows third-party sellers to list products on its websites. If those sellers offer counterfeit, stolen, or unsafe goods, Walmart could face lawsuits and reputational damage even though it did not make or directly control those products. Finally, Walmart handles an enormous volume of customer payment and personal data across its stores, apps, and websites. A serious data breach could trigger regulatory penalties, legal costs, and loss of customer trust.
The tension in Walmart's story is this: the core retail business is large, stable, and slow-growing by design. The faster-growing, higher-margin layers — advertising, Walmart+, marketplace, fulfillment services — are still a small share of total revenue but are responsible for a disproportionate share of recent margin improvement. The whole financial logic depends on whether those newer businesses can scale fast enough to meaningfully move the needle on a company with over $700 billion in annual sales. Operating expenses as a percentage of sales have been creeping up — rising 20 basis points in fiscal 2026 — partly because of depreciation on all those capital investments. The bet is that these investments eventually pay for themselves through higher-margin revenue.
