Exhibit 99.1

Email from Ben Wolff to the employees of Clearwire Corporation and the XOHM division of Sprint Nextel Corporation:

Dear Clearwire and XOHM Team Members,

I am pleased to announce that I will be recommending the following appointments to the Board of Directors of the new Clearwire following close of our transaction:

John Butler, our CFO, has informed me of his decision to leave Clearwire effective at the close of the transaction to spend more time with his family. I will miss John a great deal. He has been a tremendous partner and he has my deepest gratitude for his many contributions to Clearwire over the past 3 ¹/2 years. An external search is being initiated for John’s successor.

I will be working with each of these key leaders to finalize their organization and staffing selections, with an expectation that additional leadership positions will be announced by the end of next week, and final organization and staffing announcements completed by October 31^st. I am pleased that Barry and Atish have agreed to relocate to Seattle in the coming months. The locations for other leaders will be finalized as part of staffing plans, although I want to be clear that we will continue to have an important presence in Herndon.

Our goal in launching the new Clearwire was to fully leverage the expertise and experience from both our teams. The appointments we are announcing today are consistent with this objective and position the new Clearwire for tremendous growth and success.

There is extraordinary talent on our respective teams. Achieving the new Clearwire’s full potential, however, will take more than talent alone. It will require us to come together as a team to bring out the best in ourselves and one another. The opportunities that lie before us are virtually limitless. Here’s to building a truly great company — together.

Ben Wolff
CEO
