Sprint is nearing an agreement to purchase T-Mobile for $40 per share, multiple outlets are reporting. The deal has been rumored for months, with SoftBank CEO Masayoshi Son pledging to launch a price war with larger competitors ATT and Verizon Wireless if the deal is approved by US regulators. SoftBank completed its acquisition of Sprint for $21.6 billion last summer. Bloomberg reports that Sprints offer is roughly half stock and half cash, and would leave Deutsche Telekom with about 15 percent of T-Mobile.
