RESULTS OF OPERATIONS

The discussion of operating expenses below excludes the effects of stock- based compensation. SIRIUS believes this presentation improves the transparency of disclosure and is consistent with the way operating results are evaluated by management.

FOURTH QUARTER 2007 VERSUS FOURTH QUARTER 2006

For the fourth quarter of 2007, SIRIUS recognized total revenue of $249.8 million compared to $193.4 million for the fourth quarter of 2006. This 29.2%, or $56.4 million, increase in revenue was driven by a $60.4 million increase in subscriber revenue resulting from the net increase in subscribers of 2,297,230 from the fourth quarter of 2006.

The company's adjusted loss from operations decreased $59.6 million to ($107.2) million for the fourth quarter of 2007 from ($166.8) million for the fourth quarter of 2006 (refer to the reconciliation table of net loss to adjusted loss from operations). This decrease was driven by the increase in total revenue of $56.4 million and a $3.2 million decrease in expenses.

Satellite and transmission expenses decreased $2.4 million to $4.8 million for the fourth quarter of 2007 compared to $7.2 million for the fourth quarter of 2006 as a result of sales of certain satellite parts and lower maintenance and utility expenses in the fourth of quarter 2007.

Programming and content expenses increased $4.2 million to $60.0 million for the fourth quarter of 2007 from $55.8 million for the fourth quarter of 2006. The increase was primarily attributable to license fees associated with new programming agreements including NASCAR and compensation-related costs.

Revenue share and royalties increased $35.7 million, or 169.2%, to $56.8 million for the fourth quarter of 2007 from $21.1 million for the fourth quarter of 2006. This increase was primarily attributable to the determination of the royalty rate in December 2007 under the statutory license covering the performance of sound recordings. The 2007 royalty rate of 6% of gross revenue resulted in royalty expense of approximately $48.1 million, of which approximately $25.9 million was recorded in the fourth quarter. The growth in the company's revenues and increase in the company's OEM subscriber base also contributed to the increase in revenue share and royalties.

Customer service and billing expenses increased $3.4 million to $29.1 million for the fourth quarter of 2007 from $25.7 million for the fourth quarter of 2006. The increase was primarily attributable to higher call center operating costs necessary to accommodate the increase in the company's subscriber base. Customer service and billing expenses per average subscriber per month declined 23.1% to $1.23 for the fourth quarter of 2007 from $1.60 for the fourth quarter of 2006.

Sales and marketing expenses decreased $20.0 million to $53.1 million for the fourth quarter of 2007 from $73.1 million for the fourth quarter of 2006. This decrease was primarily attributable to lower consumer marketing and advertising and reduced cooperative marketing spend with the company's distributors compared to the year-ago fourth quarter.

Subscriber acquisition costs (SAC) decreased $21.1 million, or 17.4%, to $99.9 million for the fourth quarter of 2007 from $121.0 million for the fourth quarter of 2006. This decrease was primarily attributable to lower chipset subsidies and commissions and a higher mix of OEM gross additions.

SAC per gross subscriber addition decreased 12.6% to $90 for the fourth quarter of 2007 from $103 for the fourth quarter of 2006 driven by lower product costs, offset by a higher mix of OEM gross additions.

General and administrative expenses increased $5.6 million to $27.0 million for the fourth quarter of 2007 from $21.4 million for the fourth

quarter of 2006. The increase was primarily the result of higher legal fees and compensation-related costs.

Engineering, design and development expenses decreased $5.5 million to $7.3 million for the fourth quarter of 2007 from $12.8 million for the fourth quarter of 2006. This decrease was primarily attributable to reduced OEM tooling and manufacturing upgrades associated with the factory installation of SIRIUS radios in additional vehicle models.

SIRIUS reported a net loss of ($166.2) million, or ($0.11) per share, for the fourth quarter of 2007 compared to a net loss of ($245.6) million, or ($0.17) per share, for the fourth quarter of 2006. The adjusted net loss per share, or net loss per share excluding stock-based compensation, was ($0.10) per share for the fourth quarter of 2007 as compared to an adjusted net loss per share of ($0.14) per share for the fourth quarter of 2006 (refer to the reconciliation table of net loss per share to adjusted net loss per share).

YEAR ENDED DECEMBER 31, 2007 VERSUS YEAR ENDED DECEMBER 31, 2006

For the year ended December 31, 2007, SIRIUS recognized total revenue of $922.1 million compared with $637.2 million for the year ended December 31, 2006. This 44.7%, or $284.9 million, increase in revenue was primarily driven by a $279.5 million increase in subscriber revenue resulting from the net increase in subscribers of 2,297,230 during 2007.

The company's adjusted loss from operations decreased ($185.7) million to ($327.4) million for the year ended December 31, 2007 from ($513.1) million for the year ended December 31, 2006 (refer to the reconciliation table of net loss to adjusted loss from operations). This decrease was driven by a 44.7%, or $284.9 million, increase in total revenue which more than offset the 8.6%, or $99.1 million, increase in expenses.

Satellite and transmission expenses decreased $13.5 million to $25.7 million for the year ended December 31, 2007 from $39.2 million for the year ended December 31, 2006 as a result of sales of certain satellite parts and lower maintenance and utility expense in the fourth quarter 2007. In addition, the 2006 expenses include a $10.9 million non-recurring impairment charge associated with certain satellite long-lead time parts that were no longer needed.

Programming and content expenses increased $27.7 million to $226.4 million for the year ended December 31, 2007 from $198.7 million for the year ended December 31, 2006. The increase was primarily attributable to license fees associated with new programming agreements, including NASCAR, and compensation-related costs.

Revenue share and royalties increased $76.8 million, or 109.9%, to $146.7 million for the year ended December 31, 2007 from $69.9 million for the year ended December 31, 2006. This increase was primarily attributable to the determination of the royalty rate under the statutory license covering the performance of sound recordings. The 2007 royalty rate of 6% of gross revenue resulted in royalty expense of approximately $48.1 million, of which approximately $25.9 million was recorded in the fourth quarter. The growth in the company's revenues and increase in the company's OEM subscriber base also contributed to the increase.

Customer service and billing expenses increased $17.4 million to $93.1 million for the year ended December 31, 2007 from $75.7 million for the year ended December 31, 2006. The increase was primarily attributable to higher call center operating costs and higher credit card fees necessary to accommodate the increase in the company's subscriber base. Customer service and billing expenses per average subscriber per month declined 19.7% to $1.10 for the year ended December 31, 2007 from $1.37 for the year ended December 31, 2006.

Sales and marketing expenses decreased $26.1 million to $158.0 million for the year ended December 31, 2007 from $184.1 million for the year ended December 31, 2006. This decrease was primarily attributable to lower consumer marketing and advertising and reduced cooperative marketing spend with the company's distributors offset by higher compensation-related costs.

Subscriber acquisition costs decreased $14.9 million to $404.8 million for the year ended December 31, 2007 from $419.7 million for the year ended December 31, 2006. This decrease was primarily attributable to lower chipset

subsidies and commission costs offset by higher OEM hardware subsidies and a higher mix of OEM gross additions.

SAC per gross subscriber addition decreased 11.4% to $101 for the year ended December 31, 2007 from $114 for the year ended December 31, 2006. The improvement was driven by lower product costs offset by a higher mix of OEM gross additions.

General and administrative expenses increased $31.5 million to $111.5 million for the year ended December 31, 2007 from $80.0 million for the year ended December 31, 2006. The increase was primarily a result of higher legal fees and compensation-related costs.

Engineering, design and development expenses decreased $20.9 million to $37.8 million for the year ended December 31, 2007 from $58.7 million for the year ended December 31, 2006. This decrease was primarily attributable to reduced OEM tooling and manufacturing upgrades associated with the factory installation of SIRIUS radios in additional vehicle models offset by higher compensation-related costs.

SIRIUS reported a net loss of ($565.3) million, or ($0.39) per share, for the year ended December 31, 2007, including a ($0.05) per share impact from stock-based compensation, compared with a net loss of ($1.1) billion, or ($0.79) per share, for the year ended December 31, 2006, including a ($0.01) per share impact from the impairment loss and ($0.31) per share impact from stock-based compensation. The adjusted net loss per share, or net loss per share excluding stock-based compensation, was ($0.34) for the year ended December 31, 2007 compared with an adjusted net loss per share excluding the impairment loss and stock based compensation of ($0.47) for the year ended December 31, 2006 (refer to the reconciliation table of net loss per share to adjusted net loss per share).

    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 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) SIRIUS defines average monthly churn as the number of deactivated
        subscribers divided by average quarterly subscribers.

    (2) SIRIUS defines SAC per gross subscriber addition as subscriber
        acquisition costs, excluding stock-based compensation, and margins
        from the direct sale of SIRIUS radios and accessories divided by the
        number of gross subscriber additions for the period. SAC per gross
        subscriber addition is calculated as follows:



                                   For the Three Months     For the Years
                                    Ended December 31,    Ended December 31,
                                     2007       2006       2007       2006

     addition                           $90       $103       $101       $114



    (3) SIRIUS defines customer service and billing expenses per average
        subscriber as 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
        per average subscriber is calculated as follows:



                                   For the Three Months      For the Years
                                    Ended December 31,     Ended December 31,
                                     2007       2006        2007       2006

    Customer service and
     billing expenses               $29,288    $25,912    $93,817    $76,462
    Less:  stock-based
     compensation                      (165)      (167)      (708)      (812)
    Customer service and
     billing expenses,
     as adjusted                    $29,123    $25,745    $93,109    $75,650
    Daily weighted average
     number of subscribers        7,878,574  5,361,322  7,082,927  4,591,693
    Customer service and
     billing expenses,
     as adjusted, per
     average subscriber               $1.23      $1.60      $1.10      $1.37



    (4) SIRIUS defines free cash flow as cash flow from operating activities,
        capital expenditures, merger related costs and restricted and other
        investment activity. Free cash flow is calculated as follows:



                                    For the Three Months   For the Years
                                      Ended December 31,  Ended December 31,
                                        2007     2006      2007       2006
    Net cash used in operating
     activities                      $89,818   $34,868  $(148,766) $(421,702)
    Additions to property and
     equipment                        (7,377)   (5,459)   (65,264)   (92,674)
    Merger related costs              (6,680)        -    (29,444)         -
    Restricted and other
     investment activity                 160     1,000     24,850     13,661
    Free cash flow                   $75,921   $30,409  $(218,624) $(500,715)



    (5) SIRIUS defines ARPU as the 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:



                                   For the Three Months     For the Years
                                    Ended December 31,    Ended December 31,
                                     2007       2006       2007       2006

    Subscriber revenue              $227,658  $167,210   $854,933   $575,404
    Net advertising revenue            9,770     8,451     34,192     31,044
    Total subscriber and net
     advertising revenue            $237,428  $175,661   $889,125   $606,448
    Daily weighted average
     number of subscribers         7,878,574 5,361,322  7,082,927  4,591,693
    ARPU                              $10.05    $10.92     $10.46     $11.01



    (6) SIRIUS believes average monthly churn; SAC per gross subscriber
        addition; customer service and billing expenses per average
        subscriber; free cash flow; and ARPU provide meaningful information
        regarding operating performance and liquidity and are used for
        internal management purposes; when publicly providing the business
        outlook; as a means to evaluate period-to-period comparisons; and to
        compare the company's performance to that of its competitors. SIRIUS
        also believes that investors use current and projected metrics to
        monitor performance of the business and make investment decisions.

        SIRIUS believes the exclusion of stock-based compensation expense in
        the calculations of SAC per gross subscriber addition and 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 SIRIUS common stock, the effect of which is
        unrelated to the operational conditions that give rise to variations
        in the components of subscriber acquisition costs and customer service
        and billing expenses. Specifically, the exclusion of stock-based
        compensation expense in the calculation of SAC 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 for, or superior
        to measures of financial performance prepared in accordance with GAAP.

    (7) SIRIUS refers to net loss before taxes; other income (expense) -
        including interest and investment income, interest expense, equity in
        net loss of affiliate; depreciation; impairment charges; and stock-
        based compensation expense as adjusted loss from operations. Adjusted
        loss from operations is not a measure of financial performance under
        GAAP. The company believes adjusted loss from operations is a useful
        measure of its operating performance. The company uses adjusted loss
        from operations for budgetary and planning purposes; to assess the
        relative profitability and on-going performance of consolidated
        operations; to compare performance from period to period; and to
        compare performance to that of its competitors. The company also
        believes adjusted loss from operations is useful to investors to
        compare operating performance to the performance of other
        communications, entertainment and media companies. The company
        believes that investors use current and projected adjusted loss from
        operations to estimate the current or prospective enterprise value and
        make investment decisions.

        Because the company funds and builds-out its satellite radio system
        through the periodic raising and expenditure of large amounts of
        capital, results of operations reflect significant charges for
        interest and depreciation expense. The company believes adjusted loss
        from operations provides useful information about the operating
        performance of the business apart from the costs associated with the
        capital structure and physical plant. The exclusion of interest
        expense and depreciation is useful given fluctuations in interest
        rates and significant variation in depreciation 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. The company believes 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. The company also believes 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 the
        company's common stock. Finally, the company believes that the
        exclusion of equity in net loss of affiliate (SIRIUS Canada, Inc.) is
        useful to assess the performance of its core consolidated operations
        in the continental United States. To compensate for the exclusion of
        taxes, other income (expense), depreciation, impairment charges and
        stock-based compensation expense, the company separately measures and
        budgets for these items.

        There are material limitations associated with the use of adjusted
        loss from operations in evaluating the company compared with net loss,
        which reflects overall financial performance, including the effects of
        taxes, other income (expense), depreciation, impairment charges and
        stock-based compensation expense. The company uses adjusted 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 the
        operating results after giving effect for these costs, should refer to
        net loss as disclosed in the unaudited consolidated statements of
        operations. Since adjusted loss from operations is a non-GAAP
        financial measure, the calculation of adjusted 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 in accordance with GAAP.

    (8) SIRIUS refers to adjusted net loss and adjusted net loss per share as
        net loss per share excluding impairment charges and stock-based
        compensation expense. Adjusted net loss and adjusted net loss per
        share are not measures of financial performance under GAAP. The
        company believes adjusted net loss and adjusted net loss per share are
        useful to investors to compare its operating performance to the
        performance of other communications, entertainment and media
        companies. The company believes the exclusion of impairment charges is
        appropriate for comparability purposes as the existence, amount and
        timing of impairment charges can vary from period to period and can
        vary widely across different industries or among companies within the
        same industry. The company also believes 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 the
        company's common stock.

        There are material limitations associated with the use of adjusted net
        loss and adjusted net loss per share in evaluating the company
        compared with net loss and net loss per share, which reflects overall
        financial performance, including the effects of impairment charges and
        stock-based compensation expense. The company uses adjusted net loss
        and adjusted net loss per share 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 the operating results after giving effect for these costs,
        should refer to net loss and net loss per share as disclosed in the
        unaudited consolidated financial statements of operations. Since
        adjusted net loss and adjusted net loss per share are non-GAAP
        financial measures, the calculation of adjusted net loss and adjusted
        net loss per share 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.
