DISH has not submitted a new offer to buy Sprint Nextel, as per the deadline of tonight, so that means that SoftBank is the default suitor at this point.
DISH's decision has paved the road for SoftBank to take over the provider. Sprint shareholders will give final approval over the $21.6 billion offer next Tuesday.
DISH's full statement in regards to the withdrawal:
While DISH continues to see strategic value in a merger with Sprint, the decisions made by Sprint to prematurely terminate our due diligence process and accept extreme deal protections in its revised agreement with SoftBank, among other things, have made it impracticable for DISH to submit a revised offer by the June 18th deadline imposed by Sprint. We will consider our options with respect to Sprint, and focus our efforts and resources on completing the Clearwire tender offer."
