Uber Technologies' quarterly losses widened, a source familiar with the matter told Reuters, as the lift-sharing company wades through legal troubles and faces regulatory scrutiny across the globe. 

The Silicon Valley-based company's net loss increased to $1.46 billion in the third quarter from $1.06 billion in the previous quarter, the source said. 

Quarterly net revenue rose 14% to $2 billion and gross bookings increased 11.5% to $9.7 billion, on a sequential basis, the person said. 

As a private company, Uber is not required to publicly report its financial results, but earlier this year it began offering a glimpse of its performance by disclosing certain numbers. 

A consortium led by SoftBank Group launched a tender offer for shares of Uber yesterday. 

The Japanese company said some notable early Uber investors including venture capital firms Benchmark, which owns 13% of Uber worth $9 billion, and Menlo planned to sell stock. 

Uber has been hit by a series of scandals this year with th elatest being a regulatory crackdown after disclosing that it paid hackers $100,000 to keep secret a massive breach last year that exposed personal data from around 57 million accounts.

Meanwhile, Uber has informed Britain's data protection regulator that 2.7 million user accounts in the country were affected by the data breach in 2016, which the company disclosed last week. 

The breach involved names, mobile phone numbers and email addresses, the ride-hailing company told UK's Information Commissioner's Office (ICO). 

ICO said it expects Uber to alert all the affected users in UK as soon as possible. 

Uber failed to disclose a massive breach last year that exposed the data of some 57 million users, the company's new chief executive officer said last week. 

In Britain, Uber drew around 2.85 million users, on average, over the past three months, according to web and mobile app traffic measurement firm SimilarWeb.
