For the first nine months of this year it lost well over $2.2 billion (2.12 billion euros).

However net revenue – the amount of money from fares – continues to rise. It was reportedly $1.7 billion in the third quarter an increase from $1.1 billion between April and June.

The third quarter losses do not include Uber’s Chinese operation. It had to withdraw from the country in August selling out to rival Didi Chuxing but receiving a 5.89 percent stake in Didi and $1 billion in the deal. (Euronews)
