NEW YORK – February 9, 2012 – Sirius XM Radio (NASDAQ: SIRI) today announced full year 2011 financial and operating results, including revenue of $3.01 billion, up 7% over 2010 revenue of $2.82 billion, and adjusted EBITDA of $731 million, up 17% from $626 million in 2010.

“We are proud to announce that SiriusXM delivered another record-setting year in 2011, meeting or exceeding all of our guidance. Our strong content and subscriber focus helped set a post-merger record of 1.7 million net subscriber additions, and we achieved record levels of revenue, adjusted EBITDA and free cash flow. We expanded our adjusted EBITDA margins to 24% by tightly controlling costs and growing our revenue. Our improved profitability, coupled with lower capital expenditures, contributed to a substantial increase in our free cash flow,” noted Mel Karmazin, Chief Executive Officer, SiriusXM.

“In 2012, we expect to accelerate our revenue and adjusted EBITDA growth, and we project our free cash flow will jump by approximately 70% to $700 million. Our subscriber base will once again end this year at another all-time record high,” said Karmazin. “We continue to invest in improving the subscriber experience, all with the goal of keeping our subscribers engaged and entertained. All of us here at SiriusXM look forward to another fantastic year of subscriber growth and improved financial performance.”

Additional highlights from 2011 include:

• Subscriber growth continues. Gross additions climbed 12% to an all-time high of 8.7 million, net subscriber additions improved by 20% to 1.7 million from 1.4 million in 2010, and the subscriber base rose to an all-time high of 21.9 million subscribers at year-end. Self-pay net additions were 1.2 million in 2011, up 24% from 1.0 million in 2010.

• Stable churn. Self-pay churn was 1.9% in 2011, in-line with 2010’s results. New vehicle consumer conversion rate was 45% in 2011 compared to 46% in 2010.

• Strong cost controls. Total cash operating expenses rose 3.7%, while fixed expenses declined by 1.9%.

• SAC per gross addition declined. Subscriber acquisition costs (SAC) per gross addition improved by 7% to $55 in 2011 from $59 in 2010.

• Free cash flow grew. Free cash flow climbed to $416 million, up 98% from the $210 million generated in 2010 due to higher operating cash flow and lower capital expenditures.

GAAP net income for 2011 and 2010 was $427 million and $43 million, respectively, or $0.07 and $0.01 per diluted share, respectively.

“We ended the year with $774 million of cash, even after reducing our long-term debt by over $200 million in 2011. Our leverage at year-end improved to 4.1x our adjusted EBITDA on a gross basis and 3.1x on a net basis,” said David Frear, SiriusXM’s Executive Vice President and Chief Financial Officer. “With no debt maturities due this year and our growing free cash flow, we expect to end 2012 with nearly $1.5 billion of cash.”

2012 GUIDANCE

The Company expects its subscriber base to grow by approximately 1.3 million net subscribers and end the year at approximately 23.2 million. The company now expects adjusted EBITDA in 2012 of approximately $875 million, an increase from prior guidance of $860 million. The Company reiterates its existing 2012 revenue and free cash flow guidance:

• Revenue of approximately $3.3 billion, and

• Free cash flow of approximately $700 million.

“With auto sales expected to rise in 2012, and what appears to be only a modest increase in churn associated with our January price increase, we expect to grow our net new subscribers by roughly 1.3 million in 2012, continuing our strong multi-year track record of subscriber growth,” said Karmazin.

See accompanying glossary of terms.

          Subscribers. The improvement in the twelve months ended December 31, 2011 was due to the 12% increase in gross subscriber additions, primarily resulting from an increase in U.S. light vehicle sales, new vehicle penetration, and returning subscriber activations, including those from previously owned vehicles. This increase in gross additions was partially offset by the 10% increase in deactivations, which was primarily due to an increase in paid promotional trial volumes along with growth in the subscriber base.

          Average Self-pay Monthly Churn remained flat at 1.9% for all periods presented. The consistent churn rate exhibits stability in the continued demand for and satisfaction with our service from existing subscribers.

          New Vehicle Consumer Conversion Rate. The decrease in the twelve months ended December 31, 2011 was primarily due to the changing mix of sales among OEMs and operational issues impacting the timing of the receipt of customer information and prompt marketing communications with buyers and lessees of vehicles.

          Metrics.

          The following table contains our key operating metrics based on our unaudited adjusted results of operations for the three and twelve months ended December 31, 2011 and 2010, respectively:

Adjusted EBITDA	$	167,277	$	144,493	$	731,018	$	626,288

See accompanying glossary of terms.

          ARPU decreased in the twelve months ended December 31, 2011. The decrease of $0.15 was driven primarily by an increase in subscription discounts offered through customer acquisition and retention programs and the decrease in the U.S. Music Royalty Fee, partially offset by an increase in sales of our premium services, including Premier packages, data services and Internet subscriptions.

          SAC, Per Gross Subscriber Addition, decreased in the twelve months ended December 31, 2011 primarily due to lower per radio subsidy rates for certain OEMs and growth in subscriber reactivations and royalties from radio manufacturers compared to the twelve months ended December 31, 2010.

          Customer Service and Billing Expenses, Per Average Subscriber, remained flat in the twelve months ended December 31, 2011, as a result of lower operating costs offset by higher call volume, handle time per call, increased agent rates and personnel costs associated with the 8% growth in daily weighted average subscribers.

          Free Cash Flowfor the twelve months ended December 31, 2011 increased principally as a result of improvements in adjusted EBITDA and decreases in capital expenditures. Net cash provided by operating activities increased $31 million to $544 million for the year ended December 31, 2011 compared to the $513 million provided by operations for the year ended December 31, 2010. Capital expenditures for property and equipment for the year ended December 31, 2011 decreased $175 million to $137 million compared to $312 million for the year ended December 31, 2010. The increase in net cash provided by operating activities was primarily the result of improved operating performance driving higher adjusted EBITDA, cash received from the merger of Sirius Canada and Canadian Satellite Radio, higher collections from subscribers and distributors, and the repayment in the first quarter of 2010 of liabilities deferred in 2009. The decrease in capital expenditures for the year ended December 31, 2011 was primarily the result of decreased satellite construction and launch expenditures due to the launch in 2010 of our XM-5 satellite. The increase in restricted and other investment activities was driven by the return of capital resulting from the merger of Sirius Canada and Canadian Satellite Radio, partially offset by proceeds from the sale of investment securities in the year ended December 31, 2010.

          Adjusted Total Revenue.Set forth below are our adjusted total revenue for the three and twelve months ended December 31, 2011 and 2010, respectively. Our adjusted total revenue includes the recognition of deferred subscriber revenues acquired in the merger between SIRIUS and XM (the “Merger”) that are not recognized in our results under purchase price accounting and the elimination of the benefit in earnings from deferred revenue associated with our investment in XM Canada acquired in the Merger.

Adjusted total revenue	$	785,696	$	740,239	$	3,025,434	$	2,838,898

For the twelve months ended December 31, 2011, the increase in subscriber revenue was primarily attributable to an increase of 8% in daily weighted average subscribers

and an increase in sales of premium services, including Premier packages, data services and Internet subscriptions, partially offset by the impact of subscription discounts offered through customer acquisition and retention programs. The increase in advertising revenue was primarily due to greater demand for audio advertising resulting in increases in the number of advertising spots sold as well as the rate charged per spot. The decrease in equipment revenue was primarily due to a reduction in aftermarket hardware subsidies earned, partially offset by increased royalties from higher OEM production. The increase in other revenue was due to increased royalty revenue from Sirius XM Canada, which was partially offset by a reduction in 2010 to the U.S. Music Royalty Fee charged on primary subscriptions.

          Adjusted EBITDA.EBITDA is defined as net income before interest and investment income (loss); interest expense, net of amounts capitalized; income tax expense and depreciation and amortization. Adjusted EBITDA removes the impact of other income and expense, losses on extinguishment of debt as well as certain other charges, such as goodwill impairment; restructuring, impairments and related costs; certain purchase price accounting adjustments and share-based payment expense.

Adjusted EBITDA	$	167,277	$	144,493	$	731,018	$	626,288

For the twelve months ended December 31, 2011, the increase was primarily due to an increase of 7%, or $187 million, in adjusted revenues, partially offset by an increase of 4%, or $82 million, in expenses included in adjusted EBITDA. The increase in adjusted revenues was primarily due to the increase in our subscriber base. The increase in expenses was primarily driven by higher revenue share and royalties expenses associated with growth in revenues, increased customer service and billing expenses associated with subscriber growth and higher subscriber acquisition costs related to the 12% increase in gross additions, partially offset by lower programming and content costs.

Glossary

Adjusted EBITDA - EBITDA is defined as net income before interest and investment income (loss); interest expense, net of amounts capitalized; income tax expense and depreciation and amortization. We adjust EBITDA to remove the impact of other income and expense, loss on extinguishment of debt as well as certain other charges discussed below. This measure is one of the primary Non-GAAP financial measures on which we (i) evaluate the performance of our businesses, (ii) base our internal budgets and (iii) compensate management. Adjusted EBITDA is a Non-GAAP financial performance measure that excludes (if applicable): (i) certain adjustments as a result of the purchase price accounting for the Merger, (ii) goodwill impairment, (iii) restructuring, impairments, and related costs, (iv) depreciation and amortization and (v) share-based payment expense. The purchase price accounting adjustments include: (i) the elimination of deferred revenue associated with the investment in XM Canada, (ii) recognition of deferred subscriber revenues not recognized in purchase price accounting, and (iii) elimination of the benefit of deferred credits on executory contracts, which are primarily attributable to third party arrangements with an OEM and programming providers. We believe adjusted EBITDA is a useful measure of the underlying trend of our operating performance, which provides useful information about our business apart from the costs associated with our physical plant, capital structure and purchase price accounting. We believe investors find this Non-GAAP financial measure useful when analyzing our results and comparing our operating performance to the performance of other communications, entertainment and media companies. We believe investors use current and projected adjusted EBITDA to estimate our current and prospective enterprise value and to make investment decisions. Because we fund and build-out our satellite radio system through the periodic raising and expenditure of large amounts of capital, our results of operations reflect significant charges for depreciation expense. The exclusion of depreciation and amortization expense is useful given significant variation in depreciation and amortization expense that can result from the potential variations in estimated useful lives, all of which can vary widely across different industries or among companies within the same industry. We believe the exclusion of restructuring, impairments and related costs is useful given the nature of these expenses. We also believe the exclusion of share-based payment expense is useful given the significant variation in expense that can result from changes in the fair value as determined using the Black-Scholes-Merton model which varies based on assumptions used for the expected life, expected stock price volatility and risk-free interest rates.

Adjusted EBITDA has certain limitations in that it does not take into account the impact to our statement of operations of certain expenses, including share-based payment expense and certain purchase price accounting for the Merger. We endeavor to compensate for the limitations of the Non-GAAP measure presented by also providing the comparable GAAP measure with equal or greater prominence and descriptions of the reconciling items, including quantifying such items, to derive the Non-GAAP measure. Investors that wish to compare and evaluate our operating results after giving effect for these costs, should refer to net income as disclosed in our consolidated

statements of operations. Since adjusted EBITDA is a Non-GAAP financial performance measure, our calculation of adjusted EBITDA may be susceptible to varying calculations; may not be comparable to other similarly titled measures of other companies; and should not be considered in isolation, as a substitute for, or superior to measures of financial performance prepared in accordance with GAAP. The reconciliation of net income to the adjusted EBITDA is calculated as follows (in thousands):

Adjusted Revenues and Operating Expenses – We define this Non-GAAP financial measure as our actual revenues and operating expenses adjusted to exclude the impact of certain purchase price accounting adjustments and share-based payment expense. We use this Non-GAAP financial measure to manage our business, set operational goals and as a basis for determining performance-based compensation for our employees. The following tables reconcile our actual revenues and operating expenses to our adjusted revenues and operating expenses for the three and twelve months ended December 31, 2011 and 2010:

ARPU - is derived from total earned subscriber revenue, net advertising revenue and other subscription-related revenue, net of purchase price accounting adjustments, divided by the number of months in the period, divided by the daily weighted average number of subscribers for the period. Other subscription-related revenue includes the U.S. Music Royalty Fee, which was initially charged to subscribers in the third quarter of 2009. Purchase price accounting adjustments include the recognition of deferred subscriber revenues not recognized in purchase price accounting associated with the Merger. ARPU is calculated as follows (in thousands, except for subscriber and per subscriber amounts):

Average self-pay monthly churn – is defined as the monthly average of self-pay deactivations for the period divided by the average number of self-pay subscribers for the period. Average self-pay churn for the year is the average of the quarterly average self-pay churn.

Customer service and billing expenses, per average subscriber- is derived from total customer service and billing expenses, excluding share-based payment expense and purchase price accounting adjustments associated with the Merger, divided by the number of months in the period, divided by the daily weighted average number of subscribers for the period. We believe the exclusion of share-based payment expense in our calculation of customer service and billing expenses, per average subscriber, is useful given the significant variation in expense that can result from changes in the fair market value of our common stock, the effect of which is unrelated to the operational conditions that give rise to variations in the components of our customer service and billing expenses. Purchase price accounting adjustments associated with the Merger include the elimination of the benefit associated with incremental share-based payment arrangements recognized at the Merger date. Customer service and billing expenses, per average subscriber, is calculated as follows (in thousands, except for subscriber and per subscriber amounts):

New vehicle consumer conversion rate – is defined as the percentage of owners and lessees of new vehicles that receive our service and convert to become self-paying subscribers after the initial promotion period. At the time satellite radio enabled vehicles are sold or leased, the owners or lessees generally receive trial subscriptions ranging from three to twelve months. 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.

Subscriber acquisition cost, per gross subscriber addition - or SAC, per gross subscriber addition, is derived from subscriber acquisition costs and margins from the direct sale of radios and accessories, excluding share-based payment expense and purchase price accounting adjustments, divided by the number of gross subscriber additions for the period. Purchase price accounting adjustments associated with the Merger include the elimination of the benefit of amortization of deferred credits on executory contracts recognized at the Merger date attributable to an OEM. SAC, per gross subscriber addition, is calculated as follows (in thousands, except for subscriber and per subscriber amounts):

Such forward-looking statements are based upon the current beliefs and expectations of our management and are inherently subject to significant business, economic and competitive uncertainties and contingencies, many of which are difficult to predict and generally beyond our control. Actual results may differ materially from the results anticipated in these forward-looking statements.

The following factors, among others, could cause actual results to differ materially from the anticipated results or other expectations expressed in the forward-looking statement: our competitive position versus other forms of audio and video entertainment; our ability to retain subscribers and maintain our average monthly revenue per subscriber; our dependence upon automakers and other third parties; potential economic recessionary trends and uncertain economic outlook; our substantial indebtedness; and the useful life of our satellites, which, in most cases, are not insured. Additional factors that could cause our results to differ materially from those described in the forward-looking statements can be found in our Annual Report on Form 10-K for the year ended December 31, 2010, which is filed with the Securities and Exchange Commission (the “SEC”) and available at the SEC’s Internet site (http://www.sec.gov). The information set forth herein speaks only as of the date hereof, and we disclaim any intention or obligation to update any forward looking statements as a result of developments occurring after the date of this communication.
