Ad growth fights heavy fuel and liability claim headwinds
- Q2 FY27 U.S. comparable sales grew 2.6 percent, dragged down 125 basis points by pharmacy pricing regulations.
- The company is using roughly $2.9 billion in tariff refunds to fund 11,000 price rollbacks.
- High-margin advertising revenue jumped 38 percent in Q2, aided by the Vibe acquisition.
- Management expects more than $2 billion in incremental fuel-related costs this fiscal year.
- Rising self-insured general liability claims are becoming a severe pressure point for operating margins.
Scale works, costs bite
Walmart's core idea still works. It uses huge scale to buy low, price low, and keep shoppers coming back. In Q2 FY27, Walmart U.S. comparable sales grew 2.6 percent, and the company took $2.9 billion in tariff refunds to fund 11,000 item price rollbacks. These price cuts are meant to drive long-term market share.
The strongest part of the bull case is mix. Advertising revenue grew 38 percent in Q2, boosted by the Vibe acquisition. U.S. eCommerce is also driving double-digit incremental margins. Management noted that 70 percent of all e-commerce orders are now delivered same day or faster. This means Walmart is no longer only a low-margin store story.
The problem is that costs are rising rapidly. A massive $2 billion expected fuel headwind and a 125 basis point drag on U.S. sales from maximum fair pricing regulations on drugs present significant friction. Furthermore, operating expenses remain pressured by higher depreciation related to supply chain automation and increased self-insurance costs.
Finn's view is balanced. Walmart is a better business than it used to be, but the stock price appears to expect a lot. The next proof point is simple: can the margin gains from advertising consistently outpace structural cost creep from depreciation, healthcare, and retail liability claims?
Low prices, more profit pools
Walmart makes most of its money by selling groceries, health products, household goods, general merchandise, fuel, and other items through stores, clubs, and online channels. Its Everyday Low Price strategy depends on buying power. Suppliers want access to Walmart's huge customer base, and Walmart uses that scale to push for low costs.
The newer profit pools are important because classic retail has thin margins. Walmart Connect sells ads to brands that want to reach shoppers near the moment they buy. Walmart is also expanding its capabilities to serve smaller advertisers with self-service tools through the Vibe acquisition. Walmart+ and Sam's Club memberships add fee income.
The model breaks if costs rise faster than sales for too long. Recent capital spending is adding depreciation, and healthcare inflation is adding labor-related cost. Walmart can be right on strategy and still disappoint investors if operating income does not grow faster than revenue.
What Walmart sells
Grocery and consumables
These products bring frequent trips and help defend Walmart's price image. They are steady, but they usually carry lower margins than many general merchandise items.
Health and wellness
Pharmacy, health products, and wellness categories add repeat demand. However, recent fair pricing regulations have pressured sales growth in this category.
General merchandise
This includes many discretionary items. Mix shifts here can significantly impact gross margin.
eCommerce and store-fulfilled delivery
Online sales are powered by stores that also act like local delivery hubs. About 70 percent of e-commerce orders are now delivered same day or better.
Sam's Club memberships
Sam's Club sells warehouse shopping access through memberships. It continues to deliver solid transaction growth.
Walmart Connect and Vibe
Brands pay Walmart to place ads across its shopping and media channels. The Vibe acquisition helps capture small business ad spend.
VIZIO and connected TV ads
VIZIO gives Walmart more connected TV and ad technology. It brings data privacy duties tied to an FTC order that runs until 2037.
Three big engines
Segment mix is based on typical annual net sales distribution. Walmart U.S. is the main driver, with roughly two-thirds of segment net sales, though International is growing rapidly.
What could go wrong
Massive fuel cost headwinds
High impact · High oddsManagement expects more than $2 billion in incremental fuel-related costs for the fiscal year. This massive expense threatens to offset margin gains from other segments.
Pharmacy pricing regulations
Medium impact · High oddsChanges in regulation around maximum fair pricing for certain drugs negatively impacted Walmart U.S. comparable sales by 125 basis points in Q2 FY27.
Operating costs outrun sales
High impact · Medium oddsHigher depreciation related to supply chain automation and increased self-insurance group health costs are structural margin pressures. The latest 10-Q explicitly cited higher self-insured general liability claims expense influenced by rising costs to resolve claims across retail and related industries.
Data and driver platform legal risk
Medium impact · Medium oddsThe VIZIO deal brought an FTC consent order tied to consumer data collection and use that remains in effect until 2037. Walmart also faces CFPB litigation over payment practices for independent contractor drivers on the Spark platform.

Walmart mainly makes money by selling goods through stores, clubs, and online channels. It also earns higher-margin income from advertising, Walmart+, Sam's Club memberships, and other services.

Advertising carries much higher margins than selling groceries. In Q2 FY27, advertising grew 38 percent, boosted by the Vibe acquisition, providing a critical offset to rising structural costs.
What is the biggest concern for Walmart stock?
