Walmart Stock Drops 10% Despite Beating Earnings Estimates

Walmart shares tumbled nearly 10% on August 20, 2026, even after America’s largest retailer delivered stronger-than-expected second-quarter results. The dramatic sell-off underscored mounting concerns about consumer spending patterns and the sustainability of growth at the retail giant, often viewed as a bellwether for the broader industry. Investors zeroed in on weaker-than-forecast domestic comparable sales and full-year earnings guidance that fell short of Wall Street expectations, overshadowing the company’s revenue beat and raised outlook.

The Bentonville, Arkansas-based retailer posted total revenue of $187.9 billion for the fiscal second quarter ended July 31, 2026, marking 5.9% year-over-year growth and surpassing the roughly $186 billion consensus estimate. Adjusted earnings per share clocked in at $0.81, rising 19.1% and beating forecasts of approximately $0.74. Operating income grew 28.8% to $9.383 billion, while gross margin expanded 96 basis points to 25.4%.

Despite these headline wins, Walmart’s US comparable sales grew just 2.6%, falling well short of Wall Street’s forecast of 3.7% and marking the slowest pace of domestic same-store sales growth since the fourth quarter of 2020. Transactions rose 1.5% while average ticket sizes increased only modestly, both coming in lower than what analysts had anticipated. The disappointing domestic performance triggered the sharp stock decline, as investors prioritized near-term consumer weakness over the company’s operational achievements.

Prescription Drug Pricing and GLP-1 Impact Drag Growth

Lower prescription drug prices played a significant role in dampening sales growth during the quarter. Maximum fair price legislation that allows Medicare to negotiate drug prices negatively impacted Walmart’s health and wellness segment. When excluding the health and wellness category, the retailer reported 3.4% same-store sales growth in core merchandise, painting a slightly healthier picture of underlying demand.

The company also noted it was lapping strong growth in GLP-1 adoption over the past two years, creating difficult year-over-year comparisons in the pharmacy business. These weight-loss and diabetes medications had driven substantial foot traffic and prescription volume in prior periods, making recent growth rates harder to sustain. The combination of regulatory pricing pressure and tough comparisons created a significant headwind for one of Walmart’s key traffic-driving categories.

Consumer Caution Emerges as Fuel Prices Rise

John David Rainey, Walmart’s Chief Financial Officer, addressed shifting consumer behavior during the company’s earnings call.

“As you go through month by month in the last quarter, you can tell when fuel prices increase and got above $4, and perhaps there’s a psychological impact to that, that there are choices that consumers are making,” Rainey told investors. “So June was a little more obvious as we look at the quarter in terms of customers making trade-offs.”

To compete for cost-conscious consumers, Walmart cut prices on thousands of items throughout the quarter, including beef, chips, and soda. These price investments, combined with higher fuel costs, partially offset the margin benefits from tariff refunds. The retailer’s grocery business posted mid-single-digit growth, led by personal care, beauty, and pet supplies, while general merchandise increased by low single digits. The divergence between categories highlighted consumers’ focus on essentials over discretionary purchases.

Digital Commerce and Advertising Shine Bright

E-commerce sales surged 23% globally, exceeding the expected 22% increase and providing a bright spot amid the otherwise cautious consumer backdrop. Walmart’s US e-commerce grew 24%, likely tied to promotions the retailer ran to compete with Amazon’s Prime Day event. Store-fulfilled delivery and marketplace expansion drove much of the digital growth, demonstrating the company’s successful omnichannel strategy.

Global advertising revenue climbed 38%, with Walmart US advertising also up 38%, as the retailer capitalized on its vast customer data and expanding digital properties. Membership fee revenue increased 17% worldwide, reflecting growing adoption of Walmart+ and subscription-based services. These higher-margin revenue streams helped support operating income growth even as core retail margins faced pressure from price investments.

Guidance Raised But Falls Short of Expectations

For the third quarter-comprising the crucial back-to-school season and the beginning of holiday planning-Walmart expects net sales to increase 3% to 3.75%, alongside adjusted earnings of $0.62 to $0.64. For fiscal year 2027, the company forecast revenue to increase by 4% to 5% and adjusted earnings of $2.80 to $2.87. While management raised its full-year outlook, the adjusted EPS guidance fell short of Wall Street’s roughly $2.90 consensus, disappointing investors who had hoped for stronger profit projections.

Management noted that roughly $2.9 billion of the quarter’s earnings surprise came from tariff refunds rather than core operations, raising questions about the sustainability of profit growth without such one-time benefits. Excluding the net impact of tariff refunds and price investments, underlying operating income growth sat at the high end of prior guidance, but investors remained focused on the conservative outlook and slowing domestic trends.

Market Impact Ripples Across Major Indexes

The massive decline in Walmart shares weighed heavily on all three major US stock indexes on August 20. The Dow Jones Industrial Average fell 0.64%, the Nasdaq Composite dropped 0.80%, and the S&P 500 declined 0.29%, with 20 of 30 Dow components trading lower. Walmart was a leading contributor to all three index declines despite being one of the lighter-weighted stocks on the Dow with a share price around $114.

With a market capitalization of approximately $826 billion, Walmart’s sell-off sent ripples through the broader retail sector and heightened concerns about consumer spending resilience. The stock drop marked a 21.3% decline over the preceding three months, reflecting growing investor anxiety about the health of the American consumer. The earnings report echoed similar warnings from other major retailers about shoppers making trade-offs amid economic uncertainty, high fuel costs, and elevated interest rates.

As the third earnings season of 2026 winds down, Walmart’s results underscore a challenging environment where simply beating estimates no longer guarantees investor approval. The market now demands not just strong current performance but also confidence in sustained future growth-a bar the retail giant struggled to clear despite its operational achievements.
