Dish Network has made a multifaceted offer to acquire all or part of Clearwire, potentially complicating Sprint’s recent proposal to acquire the rest of the wireless network operator. Sprint, which is already Clearwire’s majority stakeholder, last month announced a proposal to buy the remaining 49 percent of Clearwire. The agreement is still subject to regulatory approval. Before it could be secured, though, Dish offered to pay Clearwire $3.30 per share, topping Sprint’s $2.97 per share. The unsolicited bid values Clearwire’s shares around $5 billion.
