Exhibit 99.1 [LOGO OF SIRIUS SATELLITE RADIO] SIRIUS SATELLITE RADIO RAISES YEAR-END SUBSCRIBER PROJECTION o New Sales and Distribution Alliances Expected to Drive Additional Subscriber Growth o Company Expects to End 2004 with Approximately 1 million Subscribers NEW YORK - February 12, 2004 - SIRIUS Satellite Radio (NASDAQ: SIRI), known for delivering the very best in commercial-free music and premium sports programming to cars and homes across the country, today announced that it has increased the number of subscribers it estimates the company will acquire in 2004. SIRIUS now expects to end the year with approximately 1 million subscribers, up from the company's previous estimate of 860,000. The increase was prompted by today's announcement of agreements with EchoStar Communications Corporation (NASDAQ: DISH) and RadioShack Corporation (NYSE: RSH). Beginning in mid-2004, RadioShack stores and dealers, and distributors that offer EchoStar's DISH Network, will market SIRIUS products and service. These agreements are projected to increase dramatically SIRIUS' product availability from over 6,000 retail floors today to over 20,000 by the end of 2004. "These agreements are tremendous for SIRIUS, from both a strategic and financial perspective, and should generate significant additional subscribers," said David Frear, Executive Vice President and Chief Financial Officer of SIRIUS. "Our goal is to generate over 2 million subscribers for Sirius over the term of these multi-year agreements, starting in the second half of this year. The positive impact expected from these alliances was not incorporated into our previous sales estimates." The company also announced today that it expects full year 2004 revenue to exceed $70 million, up from the estimate of over $60 million, which was provided on the company's January 28th conference call. The company continues to expect to reach the cash-flow breakeven point of 2 million subscribers by the end of 2005. The company will hold a press conference today along with management from EchoStar and RadioShack to discuss this new alliance. The call will be web cast on the company's website, www.sirius.com, at 9:30 a.m., ET, and a replay will be available at the same location, immediately following the call.
