Dish Networks has launched a US$25.5 billion hostile offer for Sprint, a significant premium over Softbank’s US$20 billion offer unveiled in 4Q12.

Dish’s move would combine the third-largest pay-TV and mobile operators in the US, which could be a better strategic fit than Japan’s Softbank combining with Sprint. First and most importantly, Dish could combine its 2GHz LTE spectrum with the LTE spectrum of Sprint and Clearwire to build one of the strongest LTE spectrum portfolios in US, which would be the foundation for a powerful new competitor in the U.S. telecoms market. Second, using Sprint’s newly-modernized mobile network would give Dish a cost-effective way to deploy LTE in its 2GHz spectrum and meet the FCC’s rollout requirements. Third, if the deal goes ahead, Dish and Sprint could quickly offer TV, broadband and mobile bundles to compete more effectively with larger integrated telecoms players such as Verizon and AT&T.

Of course, Softbank also has synergies with Sprint, including a common focus on the new 2.5GHz TDD-LTE market, the position of challenger battling against larger mobile rivals, and the ability to combine purchasing of smartphones and other mobile devices to cut costs in a way that could make quite a difference. On the other hand, pulling off a long-distance merger would be a massive challenge.

Overall, my first take is that the Dish offer is stronger than Softbank’s both strategically and financially, and will force Softbank to strengthen its offer if it wants to win Sprint.

Based on Informa data, Dish is the third-largest U.S. payTV operator with 14 million subscriptions and 12 percent market share at end-2012, behind market-leader Comcast with 19 percent share and DirecTV with 17 percent. Sprint is the third-largest U.S. mobile operator with 56 million subscriptions and 16 percent market share at end-2012, behind Verizon Wireless with a 34 percent share and AT&T with 31 percent.
