Walmart Inc. (WMT) posted much stronger-than-expected same-store sales over its fiscal fourth quarter Tuesday while beating analysts' earnings forecasts, sending shares up 3.7% to $103.71.

Walmart said adjusted earnings for the three months ended in January came in at $1.41 per share, rising 15.6% from the same period last year and well ahead of the consensus forecast of $1.33 per share. Group revenues, the company said, hit $138.79 billion, up 6% from last year and again topping analysts' estimates. 

U.S. sale stores sales grew by 4.2%, Walmart said, well ahead of its "at least 3%" guidance issued in September and extending a 17 consecutive quarterly streak of increasing domestic sales growth. The company also reiterated its full fiscal year guidance of 3% constant currency sales growth, around $11 billion in capex, and a "decline by a low single-digit percentage range compared with FY19 adjusted" earnings per share.

""We had a good year, and I want to thank our associates for their great work and openness to change," said CEO Doug McMillon. "They continue to inspire us as we strive to serve our customers better every day. Progress on initiatives to accelerate growth, along with a favorable economic environment, helped us deliver strong comp sales and gain market share."

"We're excited about the work we're doing to reach customers in a more digitally-connected way. Our commitment to the customer is clear - we'll be there when, where and how they want to shop and deliver new, convenient experiences that are uniquely Walmart," he added.

Walmart also said e-commerce sales, perhaps the company's most important growth drives, rose 43% from the same period last year over the three months ending in January, a figure that was largely in-line with the October quarter. 

International net sales slipped 2.32% to just over $33 billion, Walmart said, while U.S. net sales rose 4.55% to $90.52 billion.
