On March 24, 2008, the U.S. Department of Justice informed SIRIUS and XM that it ended its investigation into the pending merger, that it has concluded that the merger is not anti-competitive, and that it will allow the transaction to proceed. SIRIUS and XM each obtained stockholder approval for the pending merger in November 2007. The pending merger is still subject, among other conditions, to approval of the Federal Communications Commission.

As a result of the later meeting date, SIRIUS will file with the SEC today an amendment to its Annual Report on Form 10-K to include the required information regarding its directors and executive compensation.
