đ Walmart: The worldâs largest retailer is quietly turning into a technology company
Walmart $WMT has always been seen as a boring safe bet. Low margins, huge revenues, a reliable dividend. But beneath the surface a transformation is taking place that fundamentally changes the companyâs investment story. Advertising, eâcommerce, premium membership â Walmart has quietly copied Amazonâs playbook. And so far itâs working for them.
The macro environment, however, doesnât help. Trumpâs tariffs on Chinese goods are putting direct pressure on the supply chain, and CEO Doug McMillon admitted that costs are rising every week. The Federal Reserve is keeping interest rates higher for longer and U.S. consumer sentiment is fragile. Still, Walmart trades comfortably at a P/E of 43Ă.
Historical parallel: Amazon in 2013
This is exactly what we saw with Amazon $AMZN ten years ago. A company with thin margins and massive turnover. Skeptics said, "But they hardly make any profit." Meanwhile Amazon was building an advertising business, Prime membership and cloud infrastructure, and the market rewarded that only five years later. Walmart today stands at a similar crossroads. The question is whether management can execute to the end.
đ§ Business model and the company's moat
Walmart operates over 10,750 stores in 19 countries. Each week its stores and digital platforms are visited by roughly 270 million customers. The whole business rests on three key pillars.
1. Price power. Walmart buys in such enormous volumes that no competitor can systematically undercut its prices in groceries. Revenue from the grocery segment makes up roughly 56% of sales and that is a natural resilience against Amazonâs attacks. Nobody orders fresh vegetables online at industrial scale.
2. Physical network as a logistics backbone. Over 4,600 stores in the U.S. is not just retail but a distribution infrastructure that allows delivery of groceries, goods and medicines to 93% of the American population in under three hours. Amazon cannot do that without its own brick-and-mortar stores.
3. Advertising and membership flywheel. This is the key inflection point in the whole story. Walmartâs global advertising business reached $4.4 billion. Eâcommerce accounts for 18% of net sales and has been growing over 20% annually for two consecutive years. The advertising business is pure marginâno extra warehouse, no driver. That's exactly the Amazon effect, just with a fiveâyear delay.
đ Fundamental analysis
Revenue and profitability
Walmart's revenues are growing consistently, from $572 billion in 2021 to $713 billion in 2025. Operating margin improved to 4.4% and net income reached $21.9 billion with yearâoverâyear growth of 12.6%. The key trend is clearâthe operating leverage is working. The advertising business and membership are natural margin accelerators without the need to scale physical retail.
Balance sheet
Cash stands at $10.7 billion, longâterm debt $34.6 billion. Net debt of about $30 billion is perfectly manageable for a company generating $41 billion in operating cash flow. Net Debt/EBITDA around 0.7Ă. No debt time bomb.
â ď¸ Red flag: exploding CapEx
Capital expenditures rose from $13 billion in 2022 to $26.6 billion in 2026. That cuts free cash flow roughly in half, which fell from $15.1 billion to $12.7 billion. Walmart is massively investing in logistics, automation and technologyâwhich is the right strategyâbut the immediate impact on FCF is real and many analysts overlook it.
đ° Valuation and DCF analysis
1. Conservative approach (FCF CAGR 4%, WACC 9%)
This yields a fair value of $65â75, roughly 40% below the current price of about $119.
2. Base case approach (FCF CAGR 7%, WACC 8%)
Gives a fair value of $95â105, still below the current price.
3. Optimistic approach (FCF CAGR 10%, WACC 7.5%)
Brings a modest upside to $140â155.
Today the market is buying Walmartâs story as a techâretail hybrid with an advertising flywheel and is paying a premium for it that fundamental FCF methodology does not yet fully support.
â ď¸ Risks we must not ignore
Tariffs and China.
Itâs estimated that roughly 60% of Walmartâs nonâgrocery goods come from China. Tariffs can either increase prices for consumers or squeeze Walmartâs margins. CEO McMillon openly admitted that price increases will continue into the third and fourth quarters of fiscal 2026. Walmartâs everyday lowâprice philosophy is under direct pressure, and that is an existential risk for the entire brand.
Leadership transition.
In January 2026 Walmart announced that John Furner will become president and CEO while Doug McMillon steps down after a decade at the helm. Replacing the CEO at a company with $681 billion in revenue in the middle of a trade war is not a negligible risk.
Valuation leaves no room for error.
A P/E of 43Ă for a company with a 4.4% operating margin is a premium valuation that presumes flawless execution. Any disappointment, eâcommerce slowing below 15% annually, or a slide in gross margin could trigger a sharp correction.
đ My investment view
Walmart is a classic example of a company where the business and the price tell two different stories.
The business is better than it was five years ago. The advertising flywheel truly works, eâcommerce is growing consistently, and the physical network is a competitive advantage that Amazon cannot replicate overnight.
The price is a different story. Paying 43Ă earnings for a retailer with a 4.4% operating margin doesn't make sense to me at current rates. A FCF yield of 1.3% is quite reasonable for a defensive name. And fully believing the optimistic DCF scenario in an environment of tariff wars and uncertain macro requires a lot of optimism.
Walmart is a company I want to own, but certainly not at any price.
Personally, I would target an entry price around $95. That would align with the base DCF scenario with a margin of safety of 15â20%. If the price falls below $80, I would start to question the transformational story itself and reassess.
Maximum allocation for me personally: 3â5% of the portfolio.
