SPRINT AND SOFTBANK AMEND MERGER AGREEMENT TO DELIVER

GREATER VALUE TO SPRINT STOCKHOLDERS

Increases Cash Consideration Paid to Sprint Stockholders at Closing by $4.5 Billion

Sprint’s Special Committee and Board of Directors Unanimously Approve Amended

Merger Agreement

Sprint’s Special Committee Unanimously Determines that DISH Preliminary Proposal

Not Reasonably Likely to Lead to a Superior Offer

Sprint to Adjourn June 12, 2013 Stockholder Meeting until June 25, 2013

OVERLAND PARK, Kan and TOKYO – June 10, 2013 EST / June 11, 2013 JST – Sprint Nextel Corporation (NYSE: S) (“Sprint”) and SoftBank Corp. (TSE: 9984) (“SoftBank”) announced today that they have amended the previously announced merger agreement (the “Merger Agreement”) between the two companies to deliver greater cash consideration and increased certainty to Sprint stockholders. Sprint’s Special Committee and Board of Directors have unanimously approved the amended Merger Agreement and have unanimously recommended to stockholders to vote FOR the revised SoftBank transaction. Sprint and SoftBank anticipate closing the SoftBank transaction in early July 2013, as previously communicated.


Under the amended Merger Agreement, SoftBank will deliver an additional $4.5 billion of cash to Sprint stockholders at closing, bringing the total cash consideration available to Sprint stockholders to $16.64 billion.

 

   

The cash available to stockholders has increased by $1.48 per share, from $4.02 to $5.50, based on the June 7, 2013 share count (assuming full proration).

 

   

The $4.5 billion of additional cash at closing will be funded by a reallocation of $3 billion of SoftBank’s previously proposed $4.9 billion primary investment in New Sprint and by $1.5 billion of incremental capital from SoftBank.

 

   

The price at which SoftBank will acquire shares from current Sprint shareholders will be increased from $7.30 per share to $7.65 per share, a 52% premium to the unaffected trading price prior to announcement in October 2012.

As part of the amended Merger Agreement, the pricing of SoftBank’s $1.9 billion primary investment will be increased by 19% from the previously agreed $5.25 per share to $6.25 per share. Pro forma for the transaction, the current Sprint stockholders’ resulting equity ownership in a stronger, more competitive New Sprint will be 22% while SoftBank will own approximately 78%.

SoftBank will continue to invest $1.9 billion in New Sprint at closing, which in addition to the $3.1 billion convertible debt investment made by SoftBank in October 2012, brings SoftBank’s total investment in Sprint to $5.0 billion. SoftBank and Sprint believe that the reallocation of primary capital to Sprint stockholders is warranted given the companies’ refined operating and capital expenditure synergy expectations resulting from extensive due diligence over the past nine months, as well as Sprint’s improving profitability and execution of its Network Vision plan.

Sprint also announced today that its Special Committee and Board of Directors have unanimously determined that the proposal submitted by DISH Network Corporation (“DISH”) on April 15, 2013 is not reasonably likely to lead to a “superior offer” under the Merger Agreement. Sprint has engaged with DISH since April 15 and, after receiving waivers from SoftBank under the Merger Agreement, allowed DISH due diligence to commence on May 21. Despite the Special Committee’s diligence, DISH has not put forward an actionable offer. As a consequence of the lack of progress with DISH and the improved terms from SoftBank, the Special Committee ended its discussions with DISH and will request that DISH destroy all of the Sprint confidential information made available in the course of its diligence.

“The amended agreement announced today delivers more upfront cash to Sprint stockholders, while still achieving our goal of creating a well-capitalized Sprint that is better positioned to bring meaningful competition to the US market,” said SoftBank Chairman and CEO, Masayoshi Son. “Our transaction offers significant value for Sprint stockholders and the opportunity to


realize that value in just a few weeks, without the risks associated with any other potential transaction. We look forward to working with the Sprint management team to accelerate the build out of a nationwide LTE network, increase competition in the US market and drive subscriber growth in the years ahead.”

Chairman of the Special Committee of the Sprint Board of Directors, Larry Glasscock, said, “As amended, the SoftBank transaction provides a significant cash premium, maximizes value and certainty for Sprint stockholders, and enhances Sprint’s long-term value by creating a company with an improved balance sheet, greater financial flexibility and a stronger competitive position. The amended agreement allows Sprint shareholders to receive substantial cash and to begin to participate in SoftBank upside on an expedited and low-risk basis. We believe this preserves the timing and closing certainty of the original SoftBank transaction.”

Glasscock continued, “We have expended substantial time and energy engaging with DISH over the past nine weeks, including an extensive due diligence process, but these efforts did not lead, in the Special Committee’s view, to a proposal that was reasonably likely to lead to a proposal superior to SoftBank’s.”

The revised merger agreement creates a deadline of June 18, 2013 for DISH to provide its ‘best and final’ offer and for the completion of deliberations by the Special Committee and notice to SoftBank.

The Special Committee made its decision and recommendation after long and careful deliberation. Specific steps taken by the Special Committee include:

 

   

Proactively hired network and spectrum consultants and regulatory counsel (in addition to its previously announced financial and legal advisors) to independently advise it on certain matters and these individuals participated in the extensive due diligence that was performed on DISH and its spectrum and network plans;

 

   

Directed Sprint to respond to nearly all of DISH’s numerous requests for written diligence materials;

 

   

Enabled representatives of the Committee and Sprint, as well as members of Sprint management, to engage in multiple in-person meetings with DISH as well as numerous conference calls to discuss a wide variety of diligence subjects such as network deployment, HR, IT, marketing and tax and;

 

   

Participated in numerous calls between the Committee and Sprint and their advisors and DISH and its advisors.

Additional terms of the agreement:

 

   

Amend the definition of “Superior Offer” to exclude any proposal that is not fully financed pursuant to binding commitments from recognized financial institutions.

 

   

Require Sprint to adopt a shareholder rights plan.


   

Increase the non-refundable fiduciary termination fee payable by Sprint to SoftBank in certain circumstances from $600 million to $800 million.

To give Sprint stockholders time to evaluate the amended agreement, Sprint and SoftBank have agreed to adjourn the Special Meeting of Stockholders to be convened on June 12, 2013 until June 25, 2013. Supplemental proxy materials will be filed with the SEC and distributed to stockholders in the near future and such materials and an election form will be distributed to stockholders in the near future.

Consummation of the Sprint-SoftBank merger remains subject to various conditions to closing, including receipt of approval of the Federal Communications Commission and adoption of the merger agreement by Sprint’s stockholders. Sprint and SoftBank anticipate the merger will be consummated in July 2013, subject to the remaining closing conditions.
