Amazon.com Inc. posted a loss of $274 million, or 60 cents per share, in the July-September period. That's down from earnings of $63 million, or 14 cents per share, a year earlier.
The latest quarter's results include a loss of 37 cents per share related to Amazon's stake in LivingSocial. Without this charge, it still would have lost 23 cents per share, worse than what analysts are expecting.
Revenue grew 27 per cent to $13.81 billion, from $10.88 billion, falling short of analysts' expectations.
Analysts surveyed by FactSet, on average, were expecting a loss of 7 cents per share on revenue of $13.91 billion.
Amazon said its $199 Kindle Fire HD tablet is its bestselling product worldwide, but as usual, it did not give specific sales figures.
"Our approach is to work hard to charge less. Sell devices near breakeven and you can pack a lot of sophisticated hardware into a very low price point," founder and CEO Jeff Bezos said in a statement.
Amazon has a larger version of the Kindle Fire HD out next month.
Amazon's results come two days after Apple Inc. introduced a smaller iPad, the Mini, for $329. In its press release announcing the results, Amazon included a list trumpeting its high-definition Kindle Fires as cheaper than the iPad Mini and with more features. However, Apple's iPad has a much wider selection of third-party apps.
