SoftBank, which is run by the Japanese billionaire Masayoshi Son, announced on Thursday that it was terminating a $3bn share tender rescue deal hammered out last October to save WeWork from collapse.
SoftBank said it had “no choice” but to scrap the rescue deal because WeWork had failed to meet several conditions.
WeWork had repeatedly cut the price of the IPO as investors balked at its initial valuation of up to $65bn.
WeWork has grown to become the single biggest office tenant in Manhattan, and the second-largest in London after the government.
If WeWork were to go bust its landlords would struggle to collect the promised lease payments they are owed.
