A drop in online sales and rising costs have helped to push Amazon to its first loss since 2015.
Online sales at the e-commerce giant slipped 3% in the first three months of the year, as the boom to its business from the pandemic starts to fade, the firm said Thursday.
Growth in other parts of its business, including cloud computing and advertising, remained strong.
But it is wrestling with the impact of rising costs and the Ukraine war.
Overall, Amazon reported a loss of $3.8bn, much of which was driven by a hit from its investment in electric carmaker Rivian.
It forecast sales growth of as little as 3% in the coming months - a marked slowdown from the double digit growth it has enjoyed in recent years, even before the pandemic.
