Despite strong cloud growth, Amazon shares fall on revenue shortfall and lower guidance SHARE Despite higher-than-expected cloud computing revenue growth, Amazon.com Inc. saw its shares fall about 7% in after-hours trading on a second-quarter revenue shortfall and lower-than-expected guidance for the current quarter. For much of the past year, the pandemic helped Amazon.com Inc. reach new heights as more people shopped online and more businesses flocked to the cloud, and not even the easing of pandemic restrictions seemed to slow it down. But that pandemic boost appears to be over now, even as the Delta variant threatens to send more people into relative isolation once again. The retail and cloud giant said today that its second-quarter profit jumped 50% from a year ago, to $7.8 billion, or $15.12 a share. Revenue rose 27%, to $113.1 billion, though without the benefit of positive currency exchange rates, growth was 24%.
