SIRIUS XM Receives Notice Regarding Minimum Bid Price Rule

NEW YORK, Sept. 17 /PRNewswire-FirstCall/ -- SIRIUS XM Radio Inc. (Nasdaq:
SIRI) announced today that it received notice from the Nasdaq Stock Market on
September 15, 2009 that its common stock had closed below $1.00 per share for
30 consecutive business days and is therefore not in compliance with the
Nasdaq Marketplace Rule 5450(a)(1). In accordance with Marketplace Rule
5810(c)(3)(A), SIRIUS XM may regain compliance if at any time by March 15,
2010 its common stock closes at or above $1.00 for 10 consecutive business
days.

The Company intends to maintain the listing of its common stock on Nasdaq and
will consider available options if its common stock does not trade at a level
likely to result in compliance with Nasdaq's minimum bid price requirement by
March 15, 2010. This notification was expected given the reinstitution of
Nasdaq Marketplace Rule 5450(a)(1) on August 3, 2009 and has no effect on the
listing of SIRIUS XM's common stock at this time.

In May 2009, the Company's stockholders approved an amendment to its
certificate of incorporation to effect a reverse stock split at a ratio of not
less than one-for-ten and not more than one-for-fifty. The Company's board of
directors has authority to select an exchange ratio within the approved range
at any time prior to June 30, 2010. The board of directors intends to effect
the reverse stock split only if it determines the reverse split to be in the
best interests of stockholders. Such a reverse split would put the company in
compliance with the Nasdaq bid price requirement.
