Clearwire Announces Pricing of Additional $920 Million of 12 Percent Senior Secured Notes Due 2015, Expanding Note Facility to $2.78 Billion

Clearwire Corporation (NASDAQ: CLWR) today announced that Clearwire Escrow Corporation, an unrestricted subsidiary of Clearwire Communications LLC, has priced a supplemental offering of an additional $920,000,000 aggregate principal amount of 12% senior secured notes due 2015 at an issue price of 97.9% (the “Notes”). This offering is in addition to the completion of today’s offering of $1,852,494,000 aggregate principal amount of 12% senior secured notes due 2015.

“Today, we are proud to have secured an additional $920 million in debt financing, which, when coupled with the $1.56 billion of recently announced equity financing and the $1.85 billion of debt financing that we closed on today, demonstrates our ability to access the capital markets on attractive terms and in sufficient size to meet our needs, while at the same time prudently balancing equity dilution with the cost of capital,” said Bill Morrow, CEO of Clearwire. “With this latest tranche of additional funding, we have not only exceeded the amount of capital that we have previously stated we needed to fully fund our business plan, but we have also secured additional capital that will allow us to expand more aggressively by covering more people, and with more capacity than we had previously planned.”

The gross proceeds of this new debt offering will be placed in an escrow account until the consummation of the closing of the second phase of the $1.564 billion in new investment capital from Sprint Nextel Corporation, Comcast Corporation, Time Warner Cable Inc., Intel Corporation, Eagle River Holdings, LLC and Bright House Networks, LLC. As previously announced, Clearwire received approximately $1.057 billion in cash from the equity financing on November 13, 2009 and expects to receive an additional $440 million in cash at a second closing, which is targeted to be completed by year end 2009, and the remaining $66 million will be funded at a closing, which is targeted to be completed during first quarter 2010.

The notes will be issued in a private offering that is exempt from the registration requirements of the Securities Act of 1933, as amended (the “Securities Act”), to qualified institutional buyers in accordance with Rule 144A and to persons outside the U.S. pursuant to Regulation S under the Securities Act of 1933, as amended. The notes will be senior secured obligations and will be guaranteed by certain of Clearwire Communications’ wholly owned domestic subsidiaries. The Notes and the guarantees will be secured by first-priority liens on substantially all of the Clearwire Communications’ and the guarantors’ assets.

The sale of the new notes is expected to be consummated on or about December 9, 2009, subject to customary closing conditions.

Upon release of the escrow, Clearwire plans to use the proceeds for general corporate purposes.
