Howard Stern Earns Incentive Payment Reflecting Record Subscriber Growth

NEW YORK, Jan 09, 2007 /PRNewswire-FirstCall via COMTEX News Network/ -- SIRIUS Satellite Radio (Nasdaq: SIRI) today announced that it exceeded pre-Howard Stern subscriber estimates for the year ended 2006 by over two million subscribers. Based on the company's subscriber count on December 31, 2006, and pursuant to the October 2004 agreement with Stern, today Sirius delivered to affiliates of Stern 22,058,824 million shares of common stock, valued at approximately $82.9 million. This stock-based payment resulted from Sirius' December 31, 2006 subscriber count exceeding a specified target by more than two million subscribers. This target was agreed upon in October 2004 based upon the consensus estimate of securities analysts at that time of approximately 3.5 million Sirius subscribers at December 31, 2006. Sirius ended 2006 with approximately 6,024,000 subscribers.

"The decision to bring Howard Stern to SIRIUS required a very significant commitment and we are very pleased that our investment has dramatically paid off," said Mel Karmazin, CEO of SIRIUS. "SIRIUS has significantly outperformed earlier subscriber expectations, now generating over $300 million more revenue than Wall Street expected at the time Howard agreed to join us. Our exceptional programming, product offerings, and brand have led SIRIUS to set a satellite radio record in 2006 with 2.7 million net subscriber additions."

Sirius' agreement with Stern provides for additional stock-based performance bonuses if the company exceeds an escalating set of specified subscriber targets by increasing amounts substantially greater than two million. The shares of SIRIUS common stock issued, or any likely to be issued to Stern in the future, will not increase the company's fully diluted share count, as certain other currently outstanding warrants will expire without exercise in the ordinary course. Expense related to this payment has been reflected in our operating results throughout 2006.

SIRIUS intends to file a registration statement with the SEC to register these shares of common stock being delivered to affiliates of Howard Stern.
