Sirius XM Radio (SIRI)

PENDING MERGER WITH XM; SPECIAL MEETING OF STOCKHOLDERS

“Momentum for the pending merger with XM continues to build,” said Karmazin. “The public interest benefits and enhanced consumer choice that will come from the merger have garnered clear support from our customers, suppliers and other groups representing a diverse cross-section of Americans. Nearly all of the opposition to our proposed merger has been generated by those who fear enhanced competition. We will continue to work with the FCC and the DOJ to make the case that the merger offers more choices, including a la carte offerings, and lower prices for subscribers, and we continue to expect that the merger will be completed by year-end.”

A special meeting of stockholders of SIRIUS Satellite Radio is scheduled to be held in The Auditorium at the Equitable Center, 787 Seventh Avenue, New York, New York 10019, on November 13, 2007 at 9:00 a.m. The vote of each SIRIUS stockholder is very important and the merger with XM cannot be completed unless SIRIUS stockholders approve the amendment to SIRIUS’ certificate of incorporation and the issuance of SIRIUS capital stock in connection with the merger. Information about the meeting, the merger and other business to be considered by stockholders is contained in the Proxy Statement mailed to stockholders on or about October 9, 2007. Stockholders are urged to read the Proxy Statement carefully.
