XM-Sirius Merger Passes Department of Justice Antitrust Scrutiny

WASHINGTON, May 12 /PRNewswire-FirstCall/ -- XM Satellite Radio Holdings Inc. (NASDAQ: XMSR) today announced earnings for the three-month period ended March 31, 2008.

XM ended first quarter 2008 with 9.33 million subscribers, an 18 percent increase, compared to 7.91 million subscribers at the end of first quarter 2007. This growth was driven by a 49 percent year-over-year increase in the number of gross additions through the automotive (OEM) channel. First quarter 2008 OEM gross additions were 802 thousand, compared to 537 thousand in first quarter 2007.

"In first quarter 2008 we delivered the largest number of new customers from the automotive channel in XM's history, marking the fourth consecutive quarter of record OEM gross additions," said Nate Davis, president and chief executive officer of XM Satellite Radio. "XM's ongoing investment in the OEM channel is paying dividends in the form of record customer additions and continued revenue growth as our OEM partners further expand XM's reach to millions of consumers."

In first quarter 2008, XM reported total gross additions of 1.034 million, and 303 thousand net subscriber additions, compared to 868 thousand gross additions and 285 thousand net subscriber additions in first quarter 2007.

First quarter 2008 adjusted operating loss was $30.7 million, compared to a loss of $27 million in first quarter 2007. The first quarter 2008 adjusted operating loss includes $3.5 million of merger related expenses, compared to $9.2 million in first quarter 2007.

XM's first quarter 2008 net loss was $129 million, compared to a first quarter 2007 net loss of $122 million. For a reconciliation of XM's net loss to adjusted operating loss, see the attached financial schedules.

In first quarter 2008, XM's subscriber acquisition costs (SAC), a component of cost per gross addition (CPGA), were $73, compared to $65 in first quarter 2007. CPGA in first quarter 2008 fell below $100 to $99 for the first time since third quarter 2006 and compares to $103 in first quarter 2007.

XM continued to maintain stability in key operating metrics of conversion and churn, both of which improved year over year. First quarter 2008 conversion was 53.3 percent, compared to first quarter 2007 conversion of 51.5 percent. First quarter 2008 churn was 1.77 percent, compared to first quarter 2007 churn of 1.78 percent.

As of March 31, 2008, the company had total available liquidity of nearly $425 million comprised of approximately $212 million in cash and cash equivalents, $62.5 million remaining on its $250 million secured credit facility and a $150 million credit facility with General Motors.

During first quarter 2008 XM continued to grow its automotive customer base and, in addition to record volumes, achieved the following:

  --  XM's OEM partners produced approximately 1 million new XM-equipped
      vehicles in the first quarter 2008 alone, compared to 690 thousand in
      first quarter 2007. XM unveiled its groundbreaking NavWeather Service

      availability to include 2009 model year vehicles from Toyota, Infiniti
      and Hyundai. More recently, GM announced NavTraffic availability in 22
      of its 2009 model year vehicles. Altogether XM NavTraffic will be
      available in more than 40 Honda, GM, Toyota, Nissan and Hyundai 2009
      model year vehicles.

      Gracie Awards by the American Women in Radio and Television (AWRT),
      which recognize exemplary programming created for women, by women and

Merger Update

On March 24, 2008, the U.S. Department of Justice informed XM and Sirius that it had ended its investigation into their pending merger without taking action to block the transaction. That decision means the DOJ concluded the merger is not anti-competitive and that it will allow the transaction to proceed. The companies each obtained stockholder approval in November 2007. The pending merger is still subject to approval by the Federal Communications Commission.

  (2) Adjusted operating loss 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 share-based payment expense. 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 share-based payment expense
      and the subjective assumptions involved in those determinations, we
      believe excluding share-based payment 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 (i) interest income,
      (ii) interest expense, (iii) income taxes, (iv) depreciation and
      amortization, (v) loss from de-leveraging transactions, (vi) loss from
      impairment of investments, (vii) equity in net loss of affiliate,
      (viii) minority interest, (ix) other income (expense) and (x) share-
      based payment expense, 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 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.

          (Certain totals may not add due to the effects of rounding)

  Footnotes:
  (1)  OEM gross subscriber additions are paying subscribers newly activated
       in the reporting period and include Subscribers in OEM promotional
       periods as well as XM activated vehicles with rental car companies.

  (2)  Retail gross subscriber additions are paying subscribers newly
       activated in the reporting period and include Data services
       subscribers and commercial subscribers for 2007 only.

  (3)  OEM net subscriber additions (OEM gross subscriber additions less
       disconnects) represent the total net incremental paying subscribers
       added during the period.

  (4)  Retail net subscriber additions (Retail gross subscriber additions
       less disconnects) represent the total net incremental paying
       subscribers added during the period, including net Outsourced
       commercial subscribers for 2008.

  (5)  We measure the success of these promotional programs included in our
       OEM promotional subscriber count based on the percentage of new
       promotional subscribers that elect to receive the XM service and
       convert to self-paying subscribers after the initial promotion
       period. We refer to this as the "conversion rate."

  (6)  Monthly churn rate for the quarter represents the weighted average
       Churn rate for each month in the quarter. Churn rate represents the
       average percentage of self-paying Retail, OEM & other subscribers
       that discontinued service during the month divided by the average of
       these beginning and ending subscribers for the month. Churn rate does
       not include OEM promotional period deactivations and deactivations
       resulting from the change-out of XM activated vehicles with rental
       car companies.

  (7)  Subscribers -- Subscribers are those who are receiving and have
       agreed to pay for our service, including those who are currently in
       promotional periods paid in part by vehicle manufacturers, XM
       activated radios in vehicles for which we have a contractual right to
       receive payment for the use of our service and commercial
       establishments that receive our service through our relationship with
       a third party vendor. We count radios individually as subscribers.
       Retail 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 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. 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.

  (8)  Other subscribers include weather and other stand-alone service
       subscribers.

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

  (10) SAC - 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."

  (11) CPGA - 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).

  (12) Outsourced commercial subscribers are excluded for 2008.

  (13) Approximately 16 thousand subscribers, previously reported as Retail
       subscribers, are presented as Outsourced commercial subscribers for
       2007 for comparability.

  (14) Beginning in 2008, revenue from Outsourced commercial subscribers,
       previously reported as Subscription revenue, is reported as Other
       revenue.

  (15) Except for as stated in footnote 13, no previously reported metrics
       have been adjusted to reflect the exclusion of Outsourced commercial
       subscribers.
