Shares of Amazon.com Inc. (AMZN) - Get Report were advancing 5.9% to $1,030.00 in after-hours trading on Thursday after the internet giant beat on the top and bottom line for the fiscal third quarter, while issuing better-than-expected guidance for the fourth quarter.

The company posted adjusted earnings of 52 cents per share, trouncing consensus estimates of 3 cents per share, according to analysts surveyed by Thomson Reuters. Revenue climbed 34% year-over-year to $43.7 billion and beat analysts' estimated $41.5 billion.

TheStreet is hosting a live blog now analyzing Amazon's third quarter earnings report and investor call.

The company also gave upbeat guidance for its seasonally big fourth quarter, saying it expects revenue to come in between $56 billion and $60 billion, compared to consensus estimates of $54.2 billion. 

Amazon's cloud computing product, Amazon Web Services, saw sales jump 42% annually to $4.6 billion. That's higher than analysts' projected $4.51 billion. 

Amazon closed its blockbuster $13.7 billion acquisition of Whole Foods Market in August. This is the first quarter that that deal is being reflected in its finances and it's likely that analysts will have questions surrounding the ongoing integration of the upscale grocer when Amazon holds a call with investors later this evening. Investors are also likely to look for further details on Amazon's second headquarters, HQ2, next month's Prime Day shopping event 

All eyes will also be focused on Amazon's margins, which are an indicator of profitability. Investors have acknowledged that the company's thin margins are largely a product of its broad, continued investments in e-commerce, original content production, cloud computing and other areas.
