Standard & Poor's Ratings Services assigned its B- corporate credit rating to Clearwire with a stable outlook. "The very low speculative-grade rating on Clearwire reflects our opinion that the company will have large EBITDA losses and discretionary cash flow deficits for at least several years coupled with a substantial debt burden," said Standard & Poor's credit analyst Allyn Arden, " It also reflects our view that it has a vulnerable business position as a developmental stage company with uncertain growth prospects for fourth-generation (4G) wireless broadband services, a limited operating history, technology risk, and significant competition from existing wireline and wireless broadband services."
