It's been a rocky few months for Uber.

For the three-month period ended June 30, Uber posted a worse-than-expected loss of $4.32 per share.

That's more than the $3.19 per share loss analysts surveyed by Yahoo had forecast.

They reached 100 million per month for the first time ever, offering insight into how often consumers use the company's services.

Ryan Graves, Uber's first employee and first CEO, stepped down from the company's board of directors in May.

And then two more board members, entrepreneur Arianna Huffington and venture capital investor Matt Cohler, resigned last month.
