SIRIUS Expects to Double Number of Subscribers in 2005

NEW YORK - January 3, 2004 - SIRIUS Satellite Radio (NASDAQ: SIRI) today announced that it ended 2004 with 1,143,258 million subscribers, exceeding its end-of-year target of 1 million subscribers.  The company attributed its strong full-year results to robust retail sales, growing awareness of the benefits of satellite radio, and greater recognition by consumers of the company's premium quality programming.

"While we were looking to finish the year with 1 million subscribers, we are very pleased to have significantly exceeded that number," said Mel Karmazin, CEO of SIRIUS.  "The combination of our innovative products, diverse content and greater awareness of the SIRIUS brand, along with strong growth from the retail and automotive channels, contributed to a better-than-expected year-end figure."

SIRIUS' Sportster "Plug & Play" was a popular gift item during the holidays, as were many of the other transportable products from the satellite radio broadcaster.  The "Plug & Play" products can be used in vehicles, boats, RVs or homes, and provide a flexible, low-cost way of experiencing satellite radio.

"2004 has been a watershed year for SIRIUS with the introduction of exceptional programming and feature-rich products," added Karmazin.  "This strong finish underscores the momentum that we continue to see for our service, including commercial-free music, news, weather, traffic, entertainment and the best sports coverage in satellite radio. We believe that this enthusiasm will continue, and we expect to double our subscribers during 2005."
