WeWork filed a lawsuit in the US against SoftBank for breaching the contract.

Office-sharing giant WeWork sued SoftBank on Tuesday alleging that Japan-based technology investment group breached its contractual commitments by pulling out a $3 billion rescue plan.

The case filed in a U.S. court in Delaware comes only days after SoftBank announced it was pulling out of the plan to acquire WeWork shares and shore up the struggling business giant’s financing.

The board of directors of WeWork found the SoftBank move “a significant violation of its contractual commitments” under an arrangement between the two firms last year as well as a violation of SoftBank’s fiduciary obligations to current and former employees of the company who were to sell their equity.

The complaint alleges that SoftBank yielded to “activist investors” pressure and made the move after it had “gotten much of the benefits” under the deal, including WeWork’s board control. WeWork urges the court to compel SoftBank to meet with the deal, or pay damages.

SoftBank said it was concluding the deal last week, saying WeWork failed to fulfil its commitments, citing “few, recent, and important ongoing criminal and civil investigations” involving WeWork and its co-founder Adam Neumann. Neumann was to receive an estimated investment of $1 billion from SoftBank. The deal would also allocate around $450 million to current or former employees of WeWork who hold equity in the group.

SoftBank’s move served a stunning turn of events at troubled WeWork, once hailed as a sparkling $47 billion unicorn. Things began to crumble last year when WeWork lost capital and with Neumann pushed out, cancelled its share offering but with a lucrative package.

SoftBank has stated its move would not affect WeWork’s day-to-day operations. The Japanese firm and its Vision Fund have already committed more than $14.25 billion to WeWork.

The lawsuit says SoftBank took the action due to rising losses in their other investments, including their large technology investment fund. In recent weeks, SoftBank has seen its stock plunge on worries about the liquidity of the highly indebted firm, as global financial markets are roiled by uncertainty over the pandemic’s economic consequences.
