Uber’s new CEO will take on the challenge of driving the next wave of electric vehicles

The head of Uber Technologies Inc., David Drummond, has resigned, ending a four-year run for the top job.

In a statement on Wednesday, Uber said he was stepping down in part because of a “significant conflict of interest.”

It did not specify the nature of the conflict or what caused Drummond to step down.

The announcement came after the company posted a $1.2 billion financial loss in the fourth quarter.

Uber said it has made significant investments to increase its electric vehicle portfolio.

But some analysts have questioned whether the company has enough resources to support a future surge in electric vehicles.

Uber, the largest car-sharing service in the world, has made no secret of its desire to compete in the rapidly growing electric vehicle market.

Its growth in China, the United States, and Europe has seen it overtake rivals like Lyft Inc. and Uber, with its UberX service offering rides from car-pooling stations to people sitting in the backseat.

But the company faces challenges in both the U.S. and Europe as lawmakers push for tougher safety regulations and ride-sharing companies seek to raise capital.

The company has also faced criticism from some critics that it has overstepped its bounds in providing ride-hailing services.

Uber has faced scrutiny in recent years over its pricing of ride-share services.

The startup has been accused of offering more than half of its drivers $10 an hour and charging them for rides with their cars, despite an independent investigation finding that its drivers were earning a minimum wage and receiving benefits.

Uber is still valued at $60 billion.

In the U-S., the company earned $18.5 billion in revenue in the third quarter of 2016.

In 2017, the company reported a $23 billion loss, according to regulatory filings.
