American satellite TV provider Dish Network Corp. submitted an unsolicited bid to purchase U.S. wireless carrier Sprint Nextel Corp. for $25.5 billion US in cash and stock, Dish said. In a release Monday, Dish said it submitted an offer to acquire a 68 per cent stake in Sprint for $17.3 billion US in cash and $8.2 billion US worth of stock in a new, merged company. Dish said its bid reflects a “superior alternative” to an earlier $20.1 billion US bid Sprint received from Japanese mobile carrier Softbank Corp. in October. The company said its bid would result in $37 billion US in “net present value,” including about $11 billion US in synergies. "A transformative DISH/Sprint merger will create the only company that can offer customers a convenient, fully-integrated, nationwide bundle of in- and out-of-home video, broadband and voice services,” Charlie Ergen, Dish’s chairman, said in a statement. “he combined national footprints and scale will allow DISH/Sprint to bring improved broadband services to millions of homes with inferior or no access to competitive broadband services.” Dish said in January that it submitted an offer to buy U.S. mobile carrier Clearwire Corp. That bid was announced about a month after Sprint said it had submitted a $2.2 billion US bid to acquire the remaining 50 per cent stake in Clearwire. Reuters reported Monday that Sprint said it would evaluate Dish’s latest proposal.
