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:

SAC per gross subscriber
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

2007 2006 2007 2006

Customer service and
billing expenses $29,288 $25,912 $93,817 $76,462

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)

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.
