Walmart surges to all-time high as earnings beat on high-income shopper, e-commerce gains

Walmart on Thursday topped quarterly earnings and revenue expectations, as the discounter made significant e-commerce gains, drove profits with newer businesses like advertising and won over more high-income shoppers.

The big-box retailer said it now expects to hit the high end or slightly top its previous full-year guidance. Walmart had expected net sales growth of 3% to 4% and adjusted earnings per share of between $2.23 and $2.37.

Plus, he added, shoppers appreciate the convenience that Walmart offers. For the first time, its delivery business surpassed its store pickup in terms of volume, Rainey said.

"We've got customers that are coming to us more frequently than they have before and newer customers that we haven't traditionally had, and they're coming into a Walmart whether it's a virtual store online, or whether it's one of our physical stores," Rainey said.

Here's what the discounter reported for the fiscal first quarter compared with what Wall Street expected, according to a survey of analysts by LSEG:

Walmart's net income jumped to $5.10 billion, or 63 cents per share, in the three-month period that ended April 30, compared with $1.67 billion, or 21 cents per share, in the year-ago period.

Revenue climbed 6% from $152.30 billion in the year-ago quarter. That increase includes a benefit of roughly 1% from an additional selling day in the period. 

As the nation's largest retailer and private employer, Walmart
