Bloomberg: The slow-moving Dish Network talks to acquire T-Mobile U.S. from Deutsche Telekom are said to have stalled over concerns related to valuation and structure. The lack of momentum calls into question whether any transaction will get done this year or at all. The two companies will soon turn their attention to a spectrum auction in 2016 in which they’d either be bidding on wireless airwaves as one company or competing. “The ball is in Dish’s court.”
