AS MEG HAS MADE CLEAR, SHE IS FULLY COMMITTED TO HPE.

She made her announcement in a series of messages on Twitter just as the Uber board was holding a quarterly meeting, at which they had planned to call a vote on whether to appoint her to the job.

The internal divisions mean the search for a new leader may drag on. Even as board members speak with other candidates, including Jeffrey Immelt, who is departing as chief executive of General Electric, a lack of cohesion is apparent. Some board members are not convinced that Immelt is the right choice, given that GE’s stock price and profits have stagnated in recent years.

Four people are on the short list to succeed Kalanick, according to one person close to the process. And at an internal meeting with Uber employees last week, Liane Hornsey, the company’s senior vice-president and head of human resources, said a top candidate was expected to be chosen within the next six weeks.

Representatives for Uber, the company’s board of directors and Kalanick declined to comment, as did GE.

“As Meg has made clear, she is fully committed to HPE,” a spokesman for Hewlett Packard Enterprise said. “Our focus remains on driving the company forward and delivering for our customers, partners, employees and shareholders.”

The Uber board — which recently added new members amid a history of internal tensions — is mostly split into two camps. On one side is Kalanick, who is plotting a comeback. On the other are many of the company’s other directors, including venture capitalist Matt Cohler and private-equity investor David Trujillo, who represent Uber investors like Benchmark and TPG Capital. Garrett Camp, an Uber co-founder, and Ryan Graves, an early employee, were part of this group in supporting Whitman’s candidacy last week.

The positions of some board members — such as Wan Ling Martello, a Nestlé executive, and Yasir Al Rumayyan, who represents Saudi Arabia’s Public Investment Fund — are unclear.

As the factions have shifted, Arianna Huffington’s role has been particularly fluid. A founder of the Huffington Post who now runs a wellness company, Thrive Global, Huffington grew close to Kalanick since being appointed to the board last year, according to two people familiar with the board’s dynamics. Yet she advised him last month that resigning as Uber’s leader was a good idea.

The changing alliances have led to major disagreements within the board. Some members are upset that no chief financial officer has been appointed, even though the job has been vacant for more than two years.

There is also debate about the potential investment by SoftBank. Some board members believe that taking the money is unnecessary and potentially risky, given that Uber has US$5.5 billion of cash in the bank and SoftBank’s backing of multiple ride-hailing rivals in Asia.

Some company executives are concerned that Kalanick could use a SoftBank investment to dilute other shareholders’ stake while he continues to buy stock back from employees in a bid to amass power. And aligning with Masayoshi Son, the founder and chief executive of SoftBank, could provide Kalanick with a key ally, especially if Son seeks to appoint new board members who favour Kalanick’s return as chief executive as part of an investment.

A spokesman for SoftBank declined to comment.

According to people with knowledge of the quarterly meeting Thursday, board members’ cellphones started buzzing during the evening with text messages regarding Whitman’s removing herself from consideration. Some board members appeared crestfallen that the person they viewed as the most attractive candidate had taken herself out of the running so publicly days before she planned to spend time with the few board members she had not yet met.

In a text message between those involved in the discussions that was shown to The New York Times, one person reacted to Whitman’s announcement with a grim laugh, punctuated by an expletive.

After the news of Whitman’s decision sank in, the board continued the meeting. By the end of the evening, they had agreed to a truce in hopes of avoiding another negative round of media coverage, according to the people familiar with the meeting. Communicating directly and avoiding backstabbing, the directors agreed, was paramount.

After all, they still had a new chief executive to find.
