Amazon reported quarterly financials after the bell Thursday for its fourth quarter, the all-important holiday season for the e-commerce giant. And its numbers had some people doing a double take, after earnings per share came in at $3.75, more than double the $1.85 that analysts surveyed by Yahoo Finance were estimating. 

Net income was $1.9 billion for the quarter. For the full 2017 year, it was $3 billion. This was partly due to a tax cut that benefited Amazon to the tune of $789 million.
