Sprint confirmed in a regulatory filing that it plans to purchase the remaining 48.3 percent of Clearwire stock that it doesn’t own. Sprint would pay $2.90 per share in a $2 billion deal that would put Clearwire’s value at about $4.23 billion, according to a report in Reuters. Earlier this year, Sprint bought a chunk of Clearwire stock and grabbed a majority stake in the company. Sprint now owns 51.7 of the company’s holdings and hopes to make that 100 percent with this deal. A special committee of Clearwire’s Board of Directors is supposedly evaluating this offer.
