Walmart, which completed its $16 billion acquisition of a 77 percent stake in Flipkart in August, projected that comparable sales growth at U.S. stores next year - fiscal 2020 - would be 2.5 percent to 3.0 percent.
Walmart also estimates a slower growth rate of 35 percent for its online business in the year ending in January 2020, against expectations for 40 percent growth in the current year.
Meanwhile, fiscal 2020 sales are seen rising at least 3% over 2019 levels; US same-store sales are expected to rise between 2.5% and 3% during the same period; and net e-commerce sales projected to grow at an approximately 35% clip.
Walmart Inc. now expects 2019 adjusted earnings of between $4.65 and $4.80 per share, down from $4.90 to $5.05.
Shares were down 2.5 percent at $91.5 in premarket trading.
In August, Walmart posted its best quarterly US sales growth in a decade and raised its full-year sales and profit outlooks, showing it could hold its own against Amazon.
Since buying Jet.com for more than $3 billion two years ago, Walmart has been bulking up online, buying companies such as Bonobos and ModCloth. These include a website redesign, more online grocery offerings and acquisition of fashion brands to improve its appeal to millennial shoppers, who have typically stayed away from making purchases on the retailer's websites.
Over the years, Walmart has worked to use physical locations as distribution points for online orders of groceries and other goods, in order to retain buyers who increasingly expect quick, cheap shipping. The company said to expect operating income and earnings per share in the "low single-digit percentage range" between fiscal 2019 and fiscal 2020 when it's included-but to increase when it isn't.
The retailer will address investors at its Bentonville, Arkansas headquarters starting at 9:00 a.m.
