Amazon.com said profit tripled to nearly $10 billion from July to September as strong sales in its cloud-computing, advertising and retail units helped the company continue its rebound from postpandemic lows.

The company’s revenue increased by 13% to $143.1 billion for its third quarter, beating Wall Street expectations. Profit was $9.9 billion, more than triple the result from the same period last year. Amazon signaled net sales would be between $160 billion to $167 billion in its fourth quarter. Its shares rose by more than 3% in after-hours trading Thursday.
