Uber Technologies Inc. directors plan to vote Tuesday on board reforms and whether to pursue a major stock deal with SoftBank Group Corp. despite the surprise appointment of two new members by ousted Chief Executive Officer Travis Kalanick, two people familiar with the matter said.

Those two coordinated moves could drastically reshape the ride-hailing company's governance, while officially kick-starting what could end up being the largest private stock sale in history.

Kalanick, a co-founder who resigned as CEO under fire in June, stunned the board Friday when he named two former corporate titans to the startup's embattled board of directors. The nominations of former Merrill Lynch CEO John Thain and former Xerox CEO Ursula Burns came as Uber's board considers a slate of changes that would strip Kalanick of much of his power.
