Uber has named a new chief executive, replacing former CEO Travis Kalanick, in a move that is sure to raise concerns about the future of the ride-hailing company.

Kalanik resigned in July amid an ongoing probe by the FBI, which alleges Uber was illegally bundling its ride-sharing services with ride-booking apps, and his departure is likely to be seen as a significant departure from Kalanicky’s reputation.

“Peter will take over as the company president for the next 12 months,” a company spokesperson told The Verge.

Kalianick left the company in January after a tumultuous six-month tenure.

The company also confirmed it has hired former Google exec Marc Lorentzon as its new CFO.

Kalanaik has a history of leaving tech companies in favor of running for office.

He was fired from his role as chief operating officer at Microsoft in 2014 after a decade at the company.

Uber has also faced criticism for what some say are low wages and a culture of bullying.

Kalani, who joined Uber in 2011, has also previously criticized the company for its lack of transparency, including allegations that the company retaliated against drivers who refused to work for Uber.

He has repeatedly said that his firing from Uber was “a mistake.”

He did not respond to a request for comment.

Kalano’s tenure at Uber began in January 2018, after he stepped down as CEO in an internal email.

He took over as CEO after an abrupt and largely unrelated resignation in July 2018, in which he admitted to “mistakes” in the hiring of two former Uber employees, including former co-founder Travis Kalani.

Kalanei has said that he is not the reason the company fell behind on the Uber acquisition of Otto, which had been a major target for Kalanacki’s criticism.

Uber’s stock fell 8% in premarket trading, to $40.57.

Uber said that Kalanitchi was fired as a result of “a number of internal and external factors.”

“Our board will determine what actions are necessary to protect the company from future harm and what actions we will take to correct the past,” Uber said in a statement.

The move comes as Uber is in the midst of a major overhaul that aims to streamline the company and improve its corporate culture.

The changes will likely focus on improving the way Uber deals with drivers and their unions, Uber said.

The transition will take some time, the company said, and will be driven by Kalanicks desire to focus on the company he founded.

“I’m proud of the team we have assembled at Uber,” Kalanaki said in an interview with Business Insider.

“We have the best team in the world.”
