Walmart is likely to increase prices because of tariffs in the coming weeks, the company's chief financial officer said Thursday.

Price increases will likely begin “towards the tail end of this month, and I certainly expect more in June,” Walmart Chief Financial Officer John David Rainey told CNBC.

Despite the company's sales rising by 4.5% at U.S. stores, Rainey told Bloomberg on Thursday that “it’s a challenging environment to operate in retail right now,” as the Trump administration has yet to resolve cost pressures that have risen at a scale and speed without “historical precedent.”

Several companies that sell products at Walmart – including Adidas, Mattel, Procter & Gamble, and Stanley Black & Decker – have already raised their prices or expect to, NBC News reported.

Walmart's shares have risen nearly 8%, far ahead of Target and Costco, since President Trump's "Liberation Day" tariffs last month.

The company could benefit from shoppers’ “value-seeking behavior” amid pessimism over tariffs, Deutsche Bank researchers said, as its scale still allows it to offer “compelling price points.”
