The fact that Amazon made lots of money in 2017, both in the full year and its fiscal fourth quarter, may not surprise anybody who keeps tabs on the retailer/cloud services provider/video streamer/drone operator.
But the newsworthy thing about its latest quarterly financial report (PDF), released on Thursday, comes from comparing it to a prior earnings report from October 2017: just how bad Amazon was at predicting its bonkers Q4 income.
Amazon’s October guidance predicted (PDF) an operating income not exceeding $1.65 billion for Q4 2017—a pretty sky-high estimate, considering that the company reported $1.3 billion of operating income in Q4 2016. But that was nothing. Amazon’s Q4 2017 operating income was actually $2.1 billion—a cool 69-percent jump over the same period last year.
