July 28, 2009: Sprint Nextel announces a $483 million acquisition agreement for Virgin Mobile USA, adding 5 million pre-paid customers to Sprint Nextel, although these subscribers were counted in Sprint's total subscriber count, as Virgin Mobile USA was an MVNO on Sprint's CDMA network. October 19, 2009: Sprint Nextel agrees to acquire iPCS, one of its last remaining affiliates. Consolidation to Overland Park After the Sprint-Nextel merger, the company maintained an executive headquarters in Reston, Virginia and operational headquarters in Overland Park, Kansas. Sprint CEO Dan Hesse recognized that having two headquarters was not helping the merger effort, sent the wrong message to employees and contributed to the post-merger cultural clash. To resolve the problem, Hesse decided to consolidate all headquarters operations in the Sprint World Headquarters Campus located in Overland Park, Kansas, a suburb in the Kansas City metropolitan area. Acquisition by SoftBank Corporation On October 14, 2012, the Japanese telecommunications company SoftBank announced it intended to purchase 70% of Sprint Nextel Corporation for $20.1 billion. SoftBank stated that Sprint will remain a separate entity, and will remain a CDMA carrier until it is an all-LTE carrier. On April 15, 2013, Dish Network announced a higher bid for Sprint Nextel than the offer placed by SoftBank, with a $25.5 billion offer. On June 18, 2013, Dish retracted its bid and decided that it would instead focus on its intent to purchase Clearwire, however on June 26, 2013, Dish also retracted its bid for Clearwire, leaving the road clear for SoftBank to acquire the company. The United States Federal Communications Commission approved SoftBank's acquisition of a stake in Sprint. The FCC's acting chairwoman Mignon Clyburn and commissioner Ajit Pai both gave statements vociferously supporting the acquisition, saying the deal "serve[s] the public interest". The acquisition was completed on July 10, 2013. On August 6, 2013, SoftBank purchased approximately 2% more shares of Sprint Corporation, increasing its ownership stake in the company to 80%.
