Walmart shares came under heavy pressure on Thursday, August 20, after the retail giant reported quarterly results that exceeded expectations on revenue and adjusted earnings but revealed a significant slowdown in comparable sales. The decline highlights growing concerns about the U.S. consumer as higher fuel costs and persistent economic pressures increasingly influence household spending decisions.

Strong Earnings Could Not Offset the Sales Slowdown

Walmart reported second-quarter fiscal 2027 revenue of $187.9 billion, an increase of 5.9% year over year and above Wall Street expectations of roughly $186.8 billion. Adjusted earnings reached $0.81 per share, also exceeding the approximately $0.74 consensus estimate.

Despite the headline beat, investors focused on the weaker underlying sales performance. U.S. comparable sales excluding fuel increased only 2.6%, well below expectations of approximately 3.8% and representing Walmart’s slowest quarterly comparable-sales growth in six years. The slowdown suggests that some consumers are becoming more selective about spending, particularly as higher gasoline prices put additional pressure on household budgets.

Consumer Pressure Is Becoming a Bigger Concern

Walmart remains one of the largest indicators of the health of the U.S. consumer because of its broad exposure to groceries, household essentials and discretionary products. The company said e-commerce sales increased 24%, demonstrating continued strength in digital demand, while membership revenue also grew 17%. Walmart has also continued gaining market share among households with annual incomes above $100,000.

However, the weaker comparable-store performance points to a more complicated consumer environment. Rising fuel prices are forcing households to make spending trade-offs, while recent U.S. retail data has also shown signs of softer momentum. Walmart expects fuel costs to be approximately $2 billion higher than previously forecast, creating an additional headwind for its operations and customers.

Why Guidance Matters More Than the Earnings Beat

The market reaction was also driven by Walmart’s outlook. Although the company raised its full-year forecast and now expects fiscal-year sales growth of 4% to 5%, its third-quarter adjusted earnings guidance of $0.62 to $0.64 per share pointed to limited year-over-year earnings growth. That cautious near-term outlook overshadowed the stronger second-quarter numbers.

Walmart also received a $2.9 billion benefit from tariff refunds following a U.S. Supreme Court decision involving import duties and plans to use the proceeds partly to lower prices on approximately 11,000 products. While lower prices could help protect market share, investors will be watching whether such benefits can offset higher operating and supply-chain costs over time.

Walmart’s next results will provide an important test of whether the second-quarter slowdown represents a temporary disruption or a broader change in consumer behavior. Investors will be watching comparable sales, traffic, average transaction values, e-commerce growth, fuel costs and the company’s ability to maintain margins while keeping prices competitive. The sharp share-price decline reflects the market’s heightened sensitivity to signs of consumer weakness, making Walmart’s performance an important indicator for the wider U.S. retail sector.
