Exhibit 99.1


SIRIUS XM ADDS 257,000 NET SUBSCRIBERS IN THE FOURTH QUARTER

SIRIUS XM to Report Over $100 Million of Free Cash Flow for 2009

NEW YORK – January 19, 2010 – SIRIUS XM Radio (NASDAQ: SIRI) today announced that it ended the year with 18,772,758 subscribers, adding 257,028 net subscribers in the fourth quarter of 2009.

“Based on preliminary financial data, we expect to report over $100 million of free cash flow for 2009, an extraordinary improvement over the pro forma negative free cash flow of $552 million that the company experienced in 2008,” noted Mel Karmazin, Chief Executive Officer, SIRIUS XM. “This is the first year in our history that we have generated positive free cash flow for the entire year. Our fourth quarter subscriber results mark two consecutive quarters of net subscriber additions for SIRIUS XM and are the highest since the third quarter of 2008. Improvements in automotive sales, conversion rates and better than anticipated self-pay churn suggest that the outlook for the auto sector and the effects of the economy on our business are beginning to improve,” Mr. Karmazin added.

The company also announced that the conversion rate to a self-pay subscription from a trial included in the sale of a vehicle for the fourth quarter of 2009 was 46.4%, up from 44.2% in the fourth quarter of 2008, and that self-pay churn was 1.97% for the fourth quarter of 2009. “We expect to meet our guidance and report over $400 million in pro forma adjusted operating income, an improvement of over $500 million from the pro forma adjusted operating income for 2008, and an improvement of nearly $1 billion from the pro forma adjusted operating income for 2007, the last full year prior to the merger of SIRIUS and XM,” said David Frear, Chief Financial Officer, SIRIUS XM.

The company’s self-pay subscriber base increased by 247,182 in the fourth quarter to 15,703,932 subscribers, while total paid and unpaid trials included in the sale of a vehicle remained level with the prior quarter and the prior year at approximately 3.6 million.

SIRIUS XM plans to release full-year 2009 financial results in February 2010.

Free cash flow is calculated as net cash provided by operating activities, less additions to property and equipment, Merger related costs and restricted and other investment activity.

We refer to net loss before interest and investment income, interest expense net of amounts capitalized, income tax expense, loss from redemption of debt, loss on investments, other expense (income), restructuring and related cost, depreciation and amortization, and share related payment expense as adjusted income from operations.

Free cash flow and adjusted income from operations are not measures of financial performance under United States generally accepted accounting principles. We believe free cash flow and adjusted income from operations are useful measures of our operating performance. Pro forma free cash flow and pro forma adjusted operating income exclude the effects of stock-based compensation, purchase accounting adjustments, and includes the results of operations of XM prior to the July 28, 2008 Merger.

We measure the percentage of subscribers that receive our service and convert to self-paying after the initial promotion period. We refer to this as the “conversion rate.” At the time of sale, vehicle owners generally receive between three and twelve month prepaid trial subscriptions and we receive a subscription fee from the automaker. Promotional periods generally include the period of trial service plus 30 days to handle the receipt and processing of payments. We measure conversion rate three months after the period in which the trial service ends.

Self-pay monthly churn represents the monthly average of self-pay deactivations by the quarter divided by the average self-pay subscriber balance for the quarter.
