Amazon sales surge after Whole Foods acquisition, busy Prime Day

Amazon.com Inc. on Thursday said its sales surged over the summer and profit trounced expectations, as shoppers jumped at Prime Daypromotions on its website and bought groceries at its newly acquired chain of Whole Foods Market stores.

Shares rose more than seven per cent in after-hours trade.

Amazon is winning business from older, big box rivals by delivering virtually any product to customers at a low cost, and at times faster than it takes to buy goods from a physical store. It acquired Whole Foods for $13.7 billion US in August to help it deliver groceries to shoppers' doorsteps.

Amazon's results defied expectations that it would invest virtually all of its earnings into new areas as it has in the past. The world's largest online retailer said net income rose to $256 million US, or 52 cents per share in the quarter ended Sept. 30. Analysts on average were expecting threecents per share, according to Thomson Reuters I/B/E/S.

Sales jumped 34 per cent to $43.7 billion US in the third quarter, including $1.3 billion US in sales from the upscale grocer. Analysts had expected $42.1 billion US.

Prime Day, a summer marketing event Amazon has created to replicate the shopping frenzy that is more typical of the winter holiday season, helped boost sales.

This was "another strong performance, with top-line growth accelerating in the core retail segment," Baird Equity Research analyst Colin Sebastian said.

Still, the company is running on razor-thin profit margins compared with its peers. Amazon is building warehouses around the world to be faster than competitors to deliver goods to customers. It also has stepped up its spending on video, from original television shows to live sports, to draw more people to its website to both watch and shop.

Amazon expects an operating profit in the current quarter between $300 million US and $1.65 billion US. Analysts were expecting something in between for the holiday: $930.78 million US, according to Thomson Reuters I/B/E/S.

Amazon's share price-to-earnings ratio shows it is an expensive stock to purchase, at more than eight times that of cloud-computing rival Microsoft Corp, for instance.

"They had a massive beat on the bottom line, the outlook for Q4, which is historically conservative, was pretty reasonable... They are firing on all cylinders. The machine is churning," Benchmark Co analyst Daniel Kurnos said.

"They are going to continue to take share from everyone else and that at the end of the day we would rather see them invest for growth," Kurnos said.

The company's shares, which closed down 0.05 per cent on Thursday, rose about 7.5 per cent, topping $1,000 US in after-hours trading following the quarterly earnings statement. They had gained about 30 per cent this year.
