As stand-alone entities, Deutsche Telekom controlled 63% of T-Mobile, and SoftBank ( SFTB.Y 0.74% ) had an 83% stake in Sprint. For the new company, Deutsche Telekom will hold a 42% stake, and SoftBank will control 27%. The remaining 31% will be in the public's hands. This goes back to that loss of control and how Deutsche Telekom will be holding the cards here.
