The company said Tuesday that higher worker wages and increased spending on its online operations were among the reasons its results missed Wall Street estimates.
Greg Foran, who had been president and CEO of Wal-Mart Asia and took over Wal-Mart's U.S. business last summer, asked for investor patience.
"We're not interested in reaching our goals, but reaching them in a way which is sustainable for the long term," Foran said. "This requires a steady execution, a pace that is fast but calculated, and one that allows us to get it right."
Wal-Mart's results add to questions about the health of consumer spending. The latest government retail sales figures showed spending was flat in April, and Macy's, Kohl's and J.C. Penney announced disappointing results despite low gas prices and improvements in the job market.
Because of its size and reach, Wal-Mart is a barometer of consumer spending. The company, based in Bentonville, Ark., had a 1.1% increase in sales at U.S. Wal-Mart stores open at least a year. It was its third consecutive quarter of increases, but the growth was slightly below analysts' expectations.
The company is facing challenges, including that its low-income shoppers are struggling: Wal-Mart pointed out that its customers are either pocketing tax refunds and their savings from lower gas prices or using the extra money to pay down debt or bills like utilities.
The company also is dealing with competition from the likes of online king
Wal-Mart is doing a number of things to improve results. It's increasing its spending for its online operations to between $1.2 billion and $1.5 billion this year, up from $1 billion last year: It announced last week it was testing an unlimited free-shipping service for $50 a year, undercutting Amazon's popular Amazon Prime, whose annual dues are $99.
At its U.S. division, which accounts for 60% of its total sales, the company is trying to improve its selection and customer service, while making sure it has the lowest prices. It expects to see tidier stores and improved offerings by the holiday shopping season.
And as part of the strategy to turn around its business, the company raised the minimum wages for its hourly workers to $9 per hour in April. By February 2016, all hourly workers will make at least $10 per hour.
Wal-Mart said that net income was $3.34 billion, or $1.03 per share, for the three months that ended April 30. That compares with $3.59 billion, or $1.11 per share, a year earlier.
Revenue was down slightly to $114.0 billion, from $114.2 billion in the year-ago quarter. The quarter marked the third consecutive period of growth in revenue at stores opened at least a year, after a string of either quarterly declines or flat sales.
Analysts were expecting $1.04 per share and revenue of $116.27 billion, according to Zacks Investment Research.
Wal-Mart expected earnings per share for the current quarter to be in the range of $1.06 to $1.18 per share. Analysts expected $1.17 per share, according to FactSet.
