SIRIUS XM RADIO REPORTS FOURTH QUARTER AND
FULL YEAR 2008 RESULTS

NEW YORK – March 10, 2009 – SIRIUS XM Radio (NASDAQ: SIRI) today announced full year 2008 results, including pro forma full year 2008 revenue of $2.44 billion up 18% over 2007 pro forma revenue of $2.06 billion; total subscribers of more than 19 million up 10% from 2007 subscribers of 17.3 million; and positive pro forma adjusted income from operations in the fourth quarter of 2008.

“In the fourth quarter 2008, the company’s first full quarter of combined operations, SIRIUS XM made remarkable financial progress,” said Mel Karmazin, CEO of SIRIUS. “For the first time in company history, we reached positive pro forma adjusted income from operations of $32 million, as compared with a loss of $224 million one year ago. Fourth quarter 2008 revenue of $644 million grew 16% over the year ago quarter while total cash operating expenses declined by 22%, a clear demonstration of our focus on improving profitability. Despite challenges in the overall economy and in the auto sector, we look forward to continuing to deliver on the synergies of the merger. We are also very pleased to report that we have closed the second and final phase of the previously announced investment by Liberty Media Corporation. These transactions resolve the uncertainty surrounding the company’s and its subsidiaries’ debt maturing in 2009.”

SIRIUS XM ended the fourth quarter 2008 with 19,003,856 subscribers, up 10% from 17,348,622 subscribers at year end 2007. In the fourth quarter 2008, pro forma average revenue per subscriber (ARPU) grew to $10.60 from $10.42 in 2007. The monthly self-pay customer churn rate was 1.8% in the fourth quarter 2008, as compared with 1.7% in the fourth quarter 2007.


Fourth quarter 2008 pro forma revenue was $644 million, up 16% from fourth quarter 2007 pro forma revenue of $558 million. Subscriber acquisition costs (SAC) per gross subscriber addition was $70 in the fourth quarter of 2008, an improvement of 16% over the $83 in SAC per gross subscriber addition in the fourth quarter of 2007.

In the fourth quarter 2008, SIRIUS XM achieved positive pro forma adjusted income from operations of $31.8 million as compared with a pro forma adjusted loss from operations of ($224.1) million in the fourth quarter 2007.

PRO FORMA RESULTS OF OPERATIONS

The discussion of operating results below is based upon pro forma comparisons as if the merger occurred on January 1, 2007 and excludes the effects of stock-based compensation and purchase accounting adjustments.

FOURTH QUARTER 2008 VERSUS FOURTH QUARTER 2007

For the fourth quarter of 2008, SIRIUS XM recognized total pro forma revenue of $644.1 million compared to $557.5 million for the fourth quarter of 2007. This 15.5%, or $86.6 million, increase in revenue was driven by the net increase in subscribers of 1,655,234 from the fourth quarter of 2007.

Total ARPU for the three months ended December 31, 2008 was $10.60, compared to $10.42 for the three months ended December 31, 2007. The increase was driven by the start of our “Best of” package sales, most of which were at the $16.99 price point, and a lower mix of prepaid subscriptions from automakers in vehicles which have not sold through to end customers. These factors were partially offset by an increase in the mix of discounted OEM promotional trials, subscriber winback programs, second subscribers and a decline in net advertising revenue per average subscriber.

In the fourth quarter 2008, the company achieved positive pro forma adjusted income from operations of $31.8 million, compared to an adjusted loss from operations of ($224.1) million for the fourth quarter of 2007 (refer to the reconciliation table of net loss to adjusted income (loss) from operations). This decrease was driven by the increase in total revenue of $86.6


million and a $219.8 million decrease in operating expenses.

Programming and content costs decreased by 4%, or $3.9 million, over the prior year’s quarter as savings began to be realized.

Revenue share and royalties expense decreased by 25%, or $40.8 million, over the prior year’s quarter. The prior year quarter included a one time charge of $52 million in connection with the decision by the Copyright Royalty Board in January 2008 setting royalty rates for the performance of sound recordings effective January 1, 2007. Adjusting for this charge, royalties would have been up 10%, or $11.6 million, from the fourth quarter of 2007.

Customer service and billing costs increased 3%, or $2.0 million, from the prior year’s quarter, reflecting higher subscriber totals and improved scale efficiencies.

Sales and marketing costs declined 34%, or $42.0 million, over the prior year’s quarter due to reduced advertising and cooperative marketing spend, offset in part by higher customer retention spending. Sales and marketing costs were 13% of revenue in the fourth quarter of 2008 compared to 22% of revenue in the fourth quarter 2007.

Subscriber acquisition costs (SAC) declined 27%, or $48.0 million, and as a percent of revenue improved from 32% to 21% over the prior year’s quarter. This improvement was driven by 27% lower gross additions in the fourth quarter.

SAC, as adjusted, per gross subscriber addition improved by 16% to $70 from $83 for the three months ended December 31, 2008 and 2007, respectively. The decrease was primarily driven by lower retail and OEM subsidies due to better product economics.

General and administrative costs decreased 20%, or $12.6 million, and declined as a percent of revenue from 12% to 8% over the prior year’s quarter, reflecting lower merger costs and savings from the integration of administrative functions.

Engineering, design and development costs decreased 27%, or $3.9 million, due to lower product development costs and merger savings.

YEAR ENDED DECEMBER 31, 2008 VERSUS YEAR ENDED DECEMBER 31, 2007

For the year ended December 31, 2008, SIRIUS XM recognized total pro forma revenue of $2.4 billion compared with $2.1 billion for the year ended December 31, 2007. This 18.4%, or $378.1 million, increase in revenue was primarily driven by a $367.6 million increase in subscriber revenue resulting from the net increase in subscribers of 1,655,234 during 2008.

Total ARPU for the year ended December 31, 2008 was $10.51, compared to $10.61 for the year ended December 31, 2007. The decrease was driven by an increase in the mix of discounted OEM promotional subscriptions, subscriber winback programs, second subscribers and a decline in net advertising revenue per average subscriber.

The company's pro forma adjusted loss from operations decreased ($429.2) million to


($136.3) million for the year ended December 31, 2008 from ($565.5) million for the year ended December 31, 2007 (refer to the reconciliation table of net loss to adjusted income (loss) from operations). This decrease was driven by an 18.4%, or $378.1 million, increase in revenue and a 4.2%, or $129.5 million, decrease in expenses.

Programming and content costs for the year ended December 31, 2008 increased 11%, or $45.2 million, including a one-time payment to a programming provider of $27.5 million due upon completion of the merger. Excluding this one-time payment, programming costs increased by 4% or $17.7 million.

Revenue share and royalties expense increased by 19%, or $74.9 million, over the prior year, maintaining a flat percentage of revenue of approximately 20% in 2008 and 2007.

Customer service and billing costs increased 12%, or $26.8 million, from the prior year due to a larger subscriber base, mitigated by scale efficiencies.

Sales and marketing costs declined 17%, or $70.8 million, due to reduced advertising and cooperative marketing spend, offset in part by higher customer retention spending. As a percentage of revenue, sales and marketing costs improved from 20% in 2007 to 14% in 2008.

Subscriber acquisition costs declined nearly 12%, or $77.6 million, and as a percentage of revenue improved from 32% to 24%. This improvement was primarily driven by a 14% improvement in SAC per gross addition due to improved product economics and lower retail and OEM subsidies. Subscriber acquisition costs also declined as a result of the 5% decline in gross additions in the year.

SAC, as adjusted, per gross subscriber addition improved by 14% to $74 from $86 for the years ended December 31, 2008 and 2007, respectively. The decrease was primarily driven by lower retail and OEM subsidies due to better product economics.

General and administrative costs decreased 2%, or $4.8 million, and declined as a percent of revenue, reflecting one time costs in connection with the merger in the prior year and early integration savings.

Engineering, design and development costs decreased 17%, or $10.4 million, due to fewer OEM platform launches and lower product development costs.

FOOTNOTES TO PRESS RELEASE AND TABLES FOR NON-GAAP FINANCIAL MEASURES

This press release, including the selected financial information above, includes the following non-GAAP financial measures: average monthly churn; SAC per gross subscriber addition; customer service and billing expenses per average subscriber; free cash flow; average monthly revenue per subscriber, or ARPU; adjusted income (loss) from operations; adjusted net loss; and adjusted net loss per share. The definitions and usefulness of such non-GAAP financial measures are as follows (dollars in thousands, unless otherwise stated):

(1) Average self-pay monthly churn represents the average of self pay deactivations by the period divided by the average self pay subscriber balance for the period. 
   
(2) We measure the percentage of subscribers that receive the 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 OEM. 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. Based on our experience it may take up to 90 days after the trial service ends for subscribers to respond to our marketing communications and become self-paying subscribers.
   
(3) ARPU is derived from total earned subscriber revenue and net advertising revenue divided by the daily weighted average number of subscribers for the period. ARPU is calculated as follows (in thousands, except for per subscriber amounts):

  Unaudited Pro Forma    Unaudited Pro Forma 
    Three months ended      Twelve months ended 
  December 31,    December 31, 
  2008    2007    2008    2007

Net advertising revenue    15,776      20,571      69,933      73,340 
   Total subscriber and net advertising revenue  $ 601,310    $  519,680    $ 2,317,267    $  1,953,106 
Daily weighted average number of subscribers    18,910,689    16,629,079      18,373,274      15,342,041 
ARPU  $ 10.60    $  10.42    $ 10.51    $  10.61 

4) SAC, as adjusted, per gross subscriber addition is derived from subscriber acquisition costs and margins from the direct sale of radios and accessories, excluding stock-based compensation, divided by the number of gross subscriber additions for the period. SAC, as adjusted, per gross subscriber addition is calculated as follows (in thousands, except for per subscriber amounts):

SAC, as adjusted  $ 120,103     $  192,968     $  573,832     $  694,981  
Gross subscriber additions    1,713,210     2,336,640       7,710,306       8,077,674  
SAC, as adjusted, per gross subscriber addition  $ 70     $  83     $  74     $  86  

(5) Customer service and billing expenses, as adjusted, per average subscriber is derived from total customer service and billing expenses, excluding stock-based compensation, divided by the daily weighted average number of subscribers for the period. Customer service and billing expenses, as adjusted, per average subscriber is calculated as follows (in thousands, except for per subscriber amounts):

(7)

Average monthly self-pay churn; conversion rate; ARPU; SAC, as adjusted, per gross subscriber addition; customer service and billing expenses, as adjusted, per average subscriber; and free cash flow are not measures of financial performance under U.S. generally accepted accounting principles (“GAAP”). We believe these non-GAAP financial measures provide meaningful supplemental information regarding our operating performance and are used by us for budgetary and planning purposes; when publicly providing our business outlook; as a means to evaluate period-to-period comparisons; and to compare our performance to that of our competitors. We also believe that investors also use our current and projected metrics to monitor the performance of our business and to make investment decisions.

 
 

We believe the exclusion of stock-based compensation expense in our calculations of SAC, as adjusted, per gross subscriber addition and customer service and billing expenses, as adjusted, 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 subscriber acquisition costs and customer service and billing expenses. Specifically, the exclusion of stock-based compensation expense in our calculation of SAC, as adjusted, per gross subscriber addition is critical in being able to understand the economic impact of the direct costs incurred to acquire a subscriber and the effect over time as economies of scale are reached.

 
 

These non-GAAP financial measures are used in addition to and in conjunction with results presented in accordance with GAAP. These non-GAAP financial measures 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.

 
(8)     

We refer to net income (loss) before taxes; other income (expense)-including interest and investment income, interest expense, depreciation and amortization, restructuring and related costs and impairment of goodwill; and stock-based compensation expense as adjusted income (loss) from operations. Adjusted income (loss) from operations is not a measure of financial performance under GAAP. We believe adjusted income (loss) from operations is a useful measure of our operating performance. We use adjusted income (loss) from operations for budgetary and planning purposes; to assess the relative profitability and on-going performance of our consolidated operations; to compare our performance from period–to-period; and to compare our performance to that of our competitors.

 
 

We also believe adjusted income (loss) from operations is useful to investors to compare our operating performance to the performance of other communications, entertainment and media companies. We believe that investors use current and projected adjusted income (loss) from operations to estimate our current or 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 interest and

 
 

 

 

depreciation expense. We believe adjusted income (loss) from operations provides useful information about the operating performance of our business apart from the costs associated with our capital structure and physical plant. The exclusion of interest and depreciation and amortization expense is useful given fluctuations in interest rates and significant variation in depreciation and amortization expense that can result from the amount and timing of capital expenditures and 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 taxes is appropriate for comparability purposes as the tax positions of companies can vary because of their differing abilities to take advantage of tax benefits and because of the tax policies of the various jurisdictions in which they operate. We believe the exclusion of restructuring and related costs and impairment of goodwill is useful given the one- time nature of these transactions. We also believe the exclusion of stock-based compensation expense is useful given the significant variation in expense that can result from changes in the fair market value of our common stock. To compensate for the exclusion of taxes, other income (expense), depreciation and stock-based compensation expense, we separately measure and budget for these items.

There are material limitations associated with the use of adjusted income (loss) from operations in evaluating our company compared with net loss, which reflects overall financial performance, including the effects of taxes, other income (expense), depreciation and amortization, restructuring and related costs, impairment of goodwill and stock-based compensation expense. We use adjusted income (loss) from operations to supplement GAAP results to provide a more complete understanding of the factors and trends affecting the business than GAAP results alone. Investors that wish to compare and evaluate our operating results after giving effect for these costs, should refer to net loss as disclosed in our unaudited consolidated statements of operations. Since adjusted income (loss) from operations is a non-GAAP financial measure, our calculation of adjusted income (loss) from operations 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 the pro forma unadjusted Net loss to the pro forma Adjusted income (loss) from operations is calculated as follows:

There are material limitations associated with the use of a pro forma unadjusted results of operations in evaluating our company compared with our GAAP Results of operations, which reflects overall financial performance. We use pro forma unadjusted results of operations to supplement GAAP results to provide a more complete understanding of the factors and trends affecting the business than GAAP results alone. Investors that wish to compare and evaluate our operating results after giving effect for these costs, should refer to Results of operations as disclosed in our unaudited consolidated statements of operations. Since pro forma unadjusted results of operations is a non-GAAP financial measure, our 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.
