Over 82,000 SIRIUS tuners were sold in September 2005, a 93% increase over September 2004 SIRIUS tuner sales, and a 52% increase over August 2005 SIRIUS tuner sales.

"This increase in retail market share is extraordinarily positive for SIRIUS, especially given that we are now about to enter the busiest time of the year for us at retail," said Mel Karmazin, CEO of SIRIUS. "We have the strongest programming in all of radio, with great commercial free music, the NFL, Martha Stewart starting soon and Howard Stern coming in January of 2006, and we have innovative and competitively priced new products that are now reaching store shelves. This is an unbeatable combination that should translate into a strong fourth quarter for us."

SIRIUS also reaffirmed that it expects to have 3 million subscribers by the end of this year.
