Dara Khosrowshahi has officially told Expedia he wants to become CEO of Uber — but he hasn’t left yet

It’s a formality, but he can’t become CEO of Uber without it: Expedia CEO Dara Khosrowshahi has formally told the online travel business he has run for the last 12 years that he wants to leave.

But he hasn’t left quite yet.

In a letter sent to Expedia employees and filed with the SEC, Expedia chair Barry Diller said Khosrowshahi intends to go to Uber, but “nothing has been yet finalized.”

That’s all we will get for the near-term, Diller writes: “I know Dara would like to communicate now with all of you but I’ve asked him not to until this is fully resolved.”

Once this is finalized, Khosrowshahi plans on heading to Uber to meet his new employees, either today or tomorrow, Kara Swisher reports.

Here’s the full text of what has been filed with the SEC:

To: All Expedia Employees

Re: DK Update

As you probably know by now, Dara Khosrowshahi has been asked to lead Uber. Nothing has been yet finalized, but having extensively discussed this with Dara I believe it is his intention to accept. I also know the struggle he has been having out of both his abiding enthusiasm for Expedia’s future as well as his loyalty to all of us. I know Dara would like to communicate now with all of you but I’ve asked him not to until this is fully resolved. If Dara does leave us, it will be to my great regret but also my blessing - he’s devoted 12 great years to building this Company and if this is what he wants for his next adventure it will be with my best wishes. I say that because he deserves nothing less and I say that also because he will leave behind a tremendously talented corps of executives…

We both will be back in touch very soon.

Sincerely,

Barry Diller
