WeWork Cos. Inc. backer SoftBank Corp.'s negotiations to obtain $3 billion from Japanese lenders as part of its $9.5 billion rescue package for the embattled coworking giant hit a stumbling block, Reuters reported, citing two unnamed sources.

The lenders, Mizuho Financial Group Inc., Mitsubishi UFJ Financial Group Inc. and Sumitomo Mitsui Financial Group Inc., have hit internal lending limits to the Japanese conglomerate and are also concerned about risks involved in rescuing The We Co. unit, according to the report.

The three banks are looking for ways to offer the WeWork financing while offsetting exposure, the report noted, adding that SoftBank is now likely to enter 2020 without the package.

One of the ways to aid the required fundraising is to use some of SoftBank’s shareholding in Chinese e-commerce giant Alibaba Group Holding Ltd. as collateral, the unnamed sources told Reuters.

The purported deadlock with the Japanese lenders resulted in SoftBank recently obtaining a $1.75 billion line of credit from Goldman Sachs Group Inc., the unnamed sources told Reuters.

The news agency could not get a comment from Mizuho, MUFG, SMFG, SoftBank or Goldman.
