Some members of the WeWork board are unhappy with its leadership and plan to push WeWork CEO Adam Neumann to give up that title, according to several media reports.

The reports say the board members are connected to Japanese firm SoftBank Group, WeWork’s biggest investor. The Wall Street Journal and other outlets cited anonymous sources familiar with the matter. We Co. declined to comment and SoftBank did not respond to a request for comment.

Earlier in September WeWork delayed plans for an initial public offering.

Skepticism about WeWork’s business model has deepened since the company outlined its finances in paperwork related to the IPO . The company’s revenue has risen sharply, reaching $1.8 billion in 2018. But its losses have mounted almost as quickly, reaching $1.6 billion last year.

Co-working providers occupy 3.8 million square feet of office space in Boston, Cambridge and Somerville, according to recent research by brokerage Avison Young. The latest WeWork deal expands its local footprint to approximately 1.6 million square feet and recently signed a lease for another 87,000 square feet in Back Bay.

WeWork also has been scouting class B office space in Boston for its HQ by WeWork model, which rents entire floors up to 6,000 square feet for dedicated use by startups. However, the size of its local footprint has raised concerns about how it might impact the city office market in any eventual recession.
