It’s unclear how SoftBank could renege on its agreement with WeWork investors and crucially, with Neumann. Any effort to re-draw terms could result in a legal battle, one person said. As part of the deal, Neumann has the ability to sell $970 million worth of WeWork stock to SoftBank.

In recent internal discussions at SoftBank, some executives have said the payout to Neumann is too generous, the people with knowledge of the talks said. It may be a case of buyer’s remorse after WeWork employees expressed outrage over the favorable deal given to Neumann while the business was in turmoil. Representatives for Neumann, SoftBank and WeWork declined to comment.

Last month, the struggling WeWork parent company We Co. secured a $9.5 billion rescue package from SoftBank, an agreement that would hand about 80% of the company to the Japanese conglomerate. The deal includes $5 billion in new financing, the acceleration of a $1.5 billion existing commitment and the tender offer of as much as $3 billion.

Neumann left the company’s board as part of the rescue package and was replaced by SoftBank executive and newly appointed Chairman Marcelo Claure. The size of Neumann’s payout, which also included millions in consulting fees, has incensed some WeWork employees, who are facing job cuts this week.

To be sure, no decision has been made and SoftBank may choose to fulfill the $3 billion tender offer in its entirety. The Japanese conglomerate is in talks to receive as much as 300 billion yen ($2.8 billion) from Mitsubishi UFJ Financial Group Inc., Sumitomo Mitsui Financial Group Inc. and Mizuho Financial Group Inc., people familiar with the matter said this week. The Nikkei newspaper, which earlier reported on SoftBank’s financing talks with Japanese institutions, said the company was raising money to pay for the WeWork tender offer.

At a recent briefing in Tokyo, SoftBank billionaire founder Masayoshi Son acknowledged that this month’s financial results were “a mess” and that overvaluing WeWork was a judgment error. Son said that he had consulted with lawyers to see if he could back out of a $1.5 billion warrant SoftBank had pledged to WeWork, but they said he couldn’t. Instead, Son decided to buy even more shares at a discounted price, lowering the average cost of SoftBank’s equity in the business.
