SoftBank Group Corp. has said it sees a loss of around ¥700 billion in the year ending March on the portion of its WeWork investment held outside the Vision Fund, extending the group's expected net loss to ¥900 billion.

SoftBank maintained its forecast of a record annual operating loss of ¥1.35 trillion, announced earlier this month, as bets via the $100 billion (¥10 trillion) fund sour.

SoftBank is embroiled in a legal dispute with directors at WeWork after backing out of a $3 billion tender offer, agreed when it bailed out the office-sharing firm following a flopped IPO attempt last year.
