SoftBank, a Japanese telecommunications and Internet corporation, has confirmed via a press release and a live event in Tokyo the $20.1bn investment that would give SoftBank a 70% ownership of Sprint. The news hit the rumor mill 3 days ago and was pretty much confirmed by CNBC yesterday. The transaction is expected to close in mid-2013 pending regulatory approval.
