XM Satellite Radio Holdings Inc. Announces Third Quarter 2007 Results

Largest Quarter for New OEM Additions Fuels Year-Over-Year Third Quarter Gains in Gross and Net Subscribers; Third Quarter Ending Subscribers Exceed 8.5 Million; Year-Over-Year Revenue Increases 20 Percent

WASHINGTON, Oct. 25 /PRNewswire-FirstCall/ -- XM Satellite Radio Holdings Inc. (NASDAQ:XMSR) today announced earnings for the three-month period ended September 30, 2007. Revenue for the 2007 third quarter increased approximately 20 percent year over year to $287 million compared to $240 million in the 2006 third quarter.

XM ended the 2007 third quarter with approximately 8.57 million subscribers compared to approximately 7.19 million subscribers in the prior year period.

"During the third quarter, XM achieved year-over-year gains in both gross and net subscriber additions, despite weakness at retail, driven primarily by a record number of new automotive subscribers," said Nate Davis, president and chief executive officer, XM Satellite Radio. "We're already seeing the early results of the ramp in production of XM-equipped vehicles, which will provide XM with sustained subscriber growth for 2008 and beyond."

Davis continued, "We remain optimistic that our deal to merge with Sirius will close by the end of this year. In the meantime, we continue to work with the Federal Communications Commission and the Department of Justice to further demonstrate that this merger is in the public interest and should be approved."

For the third quarter of 2007, adjusted operating loss (formerly adjusted EBITDA) was $47 million compared to a loss of $2 million in the same period of 2006. The 2007 third quarter adjusted operating loss includes $9 million in expenses related to the company's pending merger with Sirius Satellite Radio. XM's 2007 third quarter net loss was $145 million compared to the 2006 third quarter net loss of $84 million. For a reconciliation of XM's net loss to adjusted operating loss, see the attached financial schedules.

In the 2007 third quarter, XM recorded gross subscriber additions of 952 thousand and net subscriber additions of 315 thousand compared to 868 thousand gross additions and 286 thousand net subscriber additions in the 2006 third quarter.

In the 2007 third quarter, XM's subscriber acquisition costs (SAC), a component of cost per gross addition (CPGA), were $70, including approximately $10 related to increased factory installations by new automotive partners. This compared to $59 in the third quarter of 2006. CPGA in the 2007 third quarter was $116 compared to $94 in the third quarter of 2006.

As of September 30, 2007, the company had $231 million in cash compared to $275 million at the end of June 30, 2007. As of September 30, 2007, the company also had $400 million in credit facilities, resulting in total available liquidity of $631 million.

Pending Merger with Sirius Satellite Radio

XM announced it will hold a special meeting of shareholders on November 13, 2007, to consider and vote upon a proposal to adopt the Agreement and Plan of Merger between XM and Sirius Satellite Radio. The proposed transaction, which has been approved by the Board of Directors of both companies, is also subject to regulatory review and approvals, including the Department of Justice (DOJ) and the Federal Communications Commission (FCC), and the satisfaction of customary closing conditions. The companies remain optimistic that the merger will close in late 2007.

The regulatory review process continues to move forward. On September 4, 2007, XM and Sirius each certified to the DOJ that we were in substantial compliance with its Request for Additional Information. The FCC completed its 45-day public comment and reply period. On July 24, 2007, XM and SIRIUS filed their joint reply comments with the FCC. The filing included detailed programming and pricing plans, including "best of," "family friendly," and "a la carte" packages that will give consumers more choice and better pricing options.

More than 4,500 comments have been filed in favor of the merger from individuals as well as from many prestigious organizations and businesses. The volume, diversity and strength of the public comments filed with the FCC demonstrate persuasively that the merger is in the public interest and should be approved.

XM and Sirius announced their agreement to combine in a tax-free, all- stock merger on February 19, 2007. The companies filed their Merger Agreement with the Securities and Exchange Commission on February 21, 2007. Under the terms of the agreement, XM shareholders will receive a fixed exchange ratio of 4.6 shares of Sirius common stock for each share of XM. XM and Sirius shareholders will each own approximately 50 percent of the combined company. Additional details about the merger are available at www.xmmerger.com.

(2) Adjusted operating loss (formerly Adjusted EBITDA) is net loss before
interest income, interest expense, income taxes, depreciation and
amortization, loss from de-leveraging transactions, loss from
impairment of investments, equity in net loss of affiliate, minority
interest, other income (expense) and stock-based compensation. This
non-GAAP measure should be used in addition to, but not as a
substitute for, the analysis provided in the statement of operations.
We believe Adjusted operating loss is a useful measure of our
operating performance and improves comparability between periods.
Adjusted operating loss is a significant basis used by management to
measure our success in acquiring, retaining and servicing subscribers
because we believe this measure provides insight into our ability to
grow revenues in a cost-effective manner. We believe Adjusted
operating loss is a calculation used as a basis for investors,
analysts and credit rating agencies to evaluate and compare the
periodic and future operating performances and value of our company
and similar companies in our industry.

Because we have funded the build-out of our system through the
raising and expenditure of large amounts of capital, our results of
operations reflect significant charges for depreciation, amortization
and interest expense. We believe Adjusted operating loss provides
helpful information about the operating performance of our business
apart from the expenses associated with our physical plant or capital
structure. We believe it is appropriate to exclude depreciation,
amortization and interest expense due to the variability of the
timing of capital expenditures, estimated useful lives and
fluctuation in interest rates. We exclude income taxes due to our tax
losses and timing differences, so that certain periods will reflect a
tax benefit, while others an expense, neither of which is reflective
of our operating results. Because of the variety of equity awards
used by companies, the varying methodologies for determining stock-
based compensation expense and the subjective assumptions involved in
those determinations, we believe excluding stock-based compensation
expense enhances the ability of management and investors to compare
our core operating results with those of similar companies in our
industry.

Equity in net loss of affiliate represents our share of losses in a
non-US affiliate in a similar business and over which we exercise
significant influence, but do not control. Management believes it is
appropriate to exclude this loss when evaluating the performance of
our own operations. Additionally, we exclude loss from de-leveraging
transactions, loss from impairment of investments, minority interest
and other income (expense) because these items represent activity
outside of our core business operations and can distort period to
period comparisons of operating performance.

There are limitations associated with the use of Adjusted operating
loss in evaluating our company compared with net loss, which reflects
overall financial performance. Adjusted operating loss does not
reflect the impact on our financial results of (1) interest income,
(2) interest expense, (3) income taxes, (4) depreciation and
amortization, (5) loss from de-leveraging transactions, (6) loss from
impairment of investments, (7) equity in net loss of affiliate, (8)
minority interest, (9) other income (expense) and (10) stock-based
compensation, which are included in the computation of net loss.
Users that wish to compare and evaluate our company based on our net
loss should refer to our unaudited Condensed Consolidated Statements
of Operations. Adjusted operating loss does not purport to represent
operating loss or cash flow from operating activities, as those terms
are defined under United States generally accepted accounting
principles, and should not be considered as an alternative to those
measurements as an indicator of our performance. In addition, our
measure of Adjusted operating loss may not be comparable to similarly
titled measures of other companies.

our service, including those who are currently in promotional
periods paid in part by vehicle manufacturers, as well as XM
activated radios in vehicles for which we have a contractual right
to receive payment for the use of our service. We count radios
individually as subscribers. Aftermarket subscribers consist
primarily of subscribers who purchased their radio at retail
outlets, distributors, or through XM's direct sales efforts. OEM
subscribers are self-paying subscribers whose XM radio was installed
by an OEM and are not currently in OEM promotional programs. OEM
promotional subscribers are subscribers who receive a fixed period
of XM service where XM receives revenue from the OEM for the trial
period following the initial purchase or lease of the vehicle. In
situations where XM receives no revenue from the OEM during the
trial period, the subscriber is not included in XM's subscriber
count. At the time of sale, some vehicle owners receive a three
month prepaid trial subscription. Promotional periods generally
include the period of trial service plus 30 days to handle the
receipt and processing of payments. The automated activation program
provides activated XM radios on dealer lots for test drives but XM
does not include these vehicles in its subscriber count. XM's OEM
partners generally indicate the inclusion of three months of XM
service on the window sticker of XM-enabled vehicles. XM,
historically and including the 2006 model year, receives a
negotiated rate for providing audio service to rental car companies.
Beginning with the 2007 model year, XM has entered into marketing
arrangements which govern the rate which XM receives for providing
audio service on certain rental fleet vehicles. Data services
subscribers are those subscribers that are receiving services that
include stand-alone XM WX Satellite Weather service, stand-alone XM
Radio Online service and stand-alone NavTraffic service. Stand-alone
XM WX Satellite Weather service packages range in price from $29.99
to $99.99 per month. Stand-alone XM Radio Online service is $7.99
per month. Stand-alone NavTraffic service is $9.95 per month.

(9) XM generally charges a range of $9.99-$11.87 per month for its audio
service for annual and multi-year plans and $6.99 per month for a
family plan.

(10) Subscription Revenue includes monthly subscription revenues for our
satellite audio service and data services, net of any promotions or
discounts.

(11) Net Ad Sales Revenue includes sales of advertisements and program
sponsorships on the XM system, including barter recorded at fair
value, net of agency commissions.

(12) SAC - As noted in our Form 10-K for the year ended December 31,
2006, we have revised our calculation of SAC to allow for the
direct calculation of this metric using certain line items from our
Results of Operations and Key Metrics tables. Subscriber
acquisition costs include Subsidies & distribution and the negative
gross profit on merchandise revenue. Subscriber acquisition costs
are divided by gross additions to calculate what we refer to as
"SAC." The previously reported amount under the prior definition
for the three months ended September 30, 2006 was $60.

(13) CPGA - As noted in our Form 10-K for the year ended December 31,
2006, we have revised our calculation of CPGA to allow for the
direct calculation of this metric using certain line items from our
Results of Operations and Key Metrics tables. CPGA costs include
the amounts in SAC, as well as Advertising & marketing. These costs
are divided by the gross additions for the period to calculate
CPGA. CPGA costs do not include marketing staff (included in
Retention & support) or the amortization of the GM guaranteed
payments (included in Amortization of GM liability). The previously
reported amount under the prior definition for the three months
ended September 30, 2006 was $93.
