(Telecompaper) Moody's Investors Service has downgraded Dish Networks ratings, saying the company will need a lot more capital to finance its planned 5G IoT network. The agency reduced its rating on Dish bonds to a step below investment grade, to Ba3, from B1. It cited concerns about the height of the investment needed, noting Dish's declining revenues amid the need for more capital to refinance and repay debt. Those concerns will continue until the company secures an equity investment or partners. "We also believe risk is rising due to the continuing secular decline of DBS's pay-TV subscriber base," the rating agency said.
