Rajeev Misra, a former debt-trading executive at Deutsche Bank AG and UBS AG who joined Fortress Investment Group LLC earlier this year, is leaving for SoftBank Corp., according to three sources briefed on the move.

Misra, 52, has not left New York-based Fortress yet, according to the sources, who asked not to be identified because the move has not yet been made public.

SoftBank, which paid $22 billion for control of Sprint Corp. last year, has invested in more than 1,300 technology companies and agreed earlier this month to invest $250 million for a minority stake in Legendary Entertainment.

Misra didn't immediately reply to a request for comment. A spokesmen for Fortress said he could not immediately comment and a spokesman for SoftBank declined to comment.
