Clearwire Names Finance Veteran David Sach
as Chief Financial Officer

KIRKLAND, Wash. — January 22, 2009 — Clearwire Corporation (NASDAQ: CLWR) announced today that it has named David Sach as chief financial officer, effective February 2, 2009. Sach brings nearly 30 years of finance and accounting experience in the telecommunications, music, and publishing industries.

“David is a veteran finance leader with global experience and a proven track record of success in our industry, and I am confident that he will serve our company, and our shareholders, exceptionally well,” said Benjamin G. Wolff, Clearwire chief executive officer. “As we look ahead to the rest of 2009 and beyond, David’s leadership will be instrumental as we focus on scaling our business while taking full advantage of the fundamentally different cost structure that we can achieve because of our next-generation network architecture and technology, and the substantial depth of spectrum we have in our portfolio.”

Beginning in 2005, Sach served as chief financial officer of Millicom International Cellular, S.A. (NASDAQ:MICC; Stockholmsbörsen: MIC), a wireless telecommunications firm that offers cellular services in Latin America, Africa, and Asia. During his time at Millicom, he managed a worldwide financial function comprised of 1,000 staff members, with primary responsibility for external and management reporting, planning and budgeting, treasury, tax, acquisitions and divestitures, corporate governance, and investor relations. During Sach’s tenure at Millicom, the company quadrupled revenues over a three-year period and increased its net profit margin from breakeven to 20 percent during the same time period.

Prior to Millicom, Sach served as the senior vice president, finance and chief accounting officer of Equant, NV, a $3 billion Dutch telecommunications company where his oversight and restructuring of the company’s global financial structure, systems, and processes resulted in significant efficiencies and reduced expenditures.

Before joining Equant, he was group financial controller of EMI Group, PLC where he worked to develop the necessary reporting and financial systems to support EMI Music’s conversion from records to CDs. Prior to EMI, he was vice president and chief financial officer of Thomson Professional Publishing, leading a staff of 100 performing the finance and back-office functions for the operating companies of this division of the Thomson Corporation.

Sach began his career with Price Waterhouse, LLP. He left as a senior manager serving clients in the publishing, printing, retail, computer, and advertising industries. He holds a B.A. in accounting from the State University of New York (Albany) and is a Certified Public Accountant.
