Adjusted earnings for the quarter came in at $1.69 a share, CNBC reported, which topped consensus analyst estimates of $1.21. Walmart posted overall revenue of $138.31 billion vs. estimates of $131.97 billion. The company’s stock price climbed more than 4% in pre-market trading Tuesday.

In a statement on Walmart’s Q1 earnings release, Walmart CEO Doug McMillon said the company is particularly upbeat now that more consumers are returning to pre-pandemic shopping patterns.

“Every segment performed well, and we’re encouraged by traffic and grocery market share trends,” McMillon said. “Our optimism is higher than it was at the beginning of the year. In the U.S., customers clearly want to get out and shop.”

Here are some of the key takeaways from the quarter:

• eCommerce sales grew 37% from the prior year, with strong results across all channels. eCommerce sales have more than doubled over the last two years.

• Walmart U.S. comparable-store sales climbed 6%, thanks in part to market share gains in the grocery business.

• Sam’s Club comp sales rose 7.2% year-over-year, with the brand’s eCommerce sales climbing 47%.

• Walmart International net sales declined 8.3% from a year earlier even as eCommerce sales increased 49%. Net sales were negatively impacted by $4.2 billion related to recent divestitures.

• The company raised its outlook for the current quarter and full year, saying that it expects EPS and Walmart U.S.’s operating income to increase in the high single-digits. It maintained its guidance that Walmart U.S. and Sam’s Club same-store sales will grow in the low single-digits, excluding fuel and tobacco.

Walmart officials are expected to update progress on the company’s Walmart+ subscription service in later comments, CNBC reported on Monday. The service launched in September, but Walmart has yet to share subscriber numbers. The subscription plan is considered an important piece of Walmart’s growth as the retailer tries to ward off competition from Amazon Prime.
