An Uber SUV waits for a client in Manhattan a day after it was announced that Uber co-founder Travis Kalanick will take a leave of absence as chief executive on June 14, 2017 in New York City.

Japan's SoftBank Group said on Tuesday that it was considering investing in Uber Technologies but there was no final agreement at this stage.

"If conditions on share price and a minimum of shares are not satisfactory for the SoftBank Group side, there is a possibility the SoftBank Group may not make an investment," it said in a statement.

Uber said earlier this week that a planned deal with SoftBank and Dragoneer Investment Group was moving forward. The investment could be worth up to $10 billion, two people familiar with the matter previously told Reuters.
