1. Business

We are a satellite radio provider in the United States. We currently broadcast over 130 channels of programming to listeners across the country. We offer 69 channels of 100% commercial-free music and feature 65 channels of sports, news, talk, entertainment, traffic and weather for a monthly subscription fee of $12.95.

We broadcast through our proprietary satellite radio system, which currently consists of three orbiting satellites, 124 terrestrial repeaters that receive and retransmit our signal, a satellite uplink facility and our studios. Subscribers receive our service through SIRIUS radios, which are sold by automakers, consumer electronics retailers, mobile audio dealers and through our website. Subscribers can also receive our music channels and certain other channels over the Internet. As of June 30, 2007, we had 7,142,538 subscribers.

In 2005, SIRIUS Canada Inc., a Canadian corporation owned by us, Canadian Broadcasting Corporation and Standard Radio Inc., received a license from the Canadian Radio-television and Telecommunications Commission to offer a satellite radio service in Canada. SIRIUS Canada offers 110 channels of commercial-free music and news, sports, talk and entertainment programming, including 11 channels of Canadian content. Subscribers to the SIRIUS Canada service are not included in our subscriber count.

On February 19, 2007, we and XM Radio announced a definitive agreement, under which we will combine in a tax-free, all-stock merger of equals. Under the terms of the agreement, XM Radio stockholders will receive 4.6 shares of our common stock for each share of XM Radio they own. XM Radio and our stockholders will each own approximately 50% of the combined company. The transaction is subject to approval by our stockholders and XM Radio’s stockholders, the satisfaction of customary closing conditions and regulatory review and approvals, including antitrust agencies and the Federal Communications Commission (“FCC”). We and XM Radio expect the transaction to be completed by the end of the year.

2. Principles of Consolidation and Basis of Presentation

The accompanying unaudited consolidated financial statements of Sirius Satellite Radio Inc. and subsidiaries have been prepared in accordance with U.S. generally accepted accounting principles and the instructions to Form 10-Q and Article 10 of Regulation S-X for interim financial reporting. Accordingly, they do not include all of the information and footnotes required by U.S. generally accepted accounting principles for complete financial statements. All intercompany transactions have been eliminated in consolidation.

In presenting unaudited consolidated financial statements, management makes estimates and assumptions that affect the amounts reported and related disclosures. Estimates, by their nature, are based on judgment and available information. Actual results could differ from those estimates. In the opinion of management, all normal recurring adjustments necessary for a fair presentation of the consolidated financial statements as of June 30, 2007 and for the three and six months ended June 30, 2007 and 2006 have been recorded. The results of operations for the three and six months ended June 30, 2007 are not necessarily indicative of the results that may be expected for the full year. Our unaudited consolidated financial statements should be read together with our consolidated financial statements and footnotes contained in our Annual Report on Form 10-K for the year ended December 31, 2006.

3. Summary of Significant Accounting Policies

Revenue Recognition

Revenue from subscribers consists of subscription fees; revenue derived from our agreement with Hertz; non-refundable activation fees; and the effects of mail-in rebates.

SIRIUS SATELLITE RADIO INC. AND SUBSIDIARIES
NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS - Continued
(Dollar amounts in thousands, unless otherwise stated)
(Unaudited)

We recognize subscription fees as our service is provided to a subscriber. We record deferred revenue for prepaid subscription fees and amortize these prepayments to revenue ratably over the term of the respective subscription plan.

At the time of sale, vehicle owners purchasing or leasing a vehicle with a subscription to our service typically receive between a six month and one year prepaid subscription. We receive payment from automakers for these subscriptions in advance of our service being activated. Such prepayments are recorded to deferred revenue and amortized ratably over the service period upon activation and sale to a customer. We also reimburse automakers for certain costs associated with the SIRIUS radio installed in the applicable vehicle at the time the vehicle is manufactured. The associated payments to the automakers are included in subscriber acquisition costs. Although we receive payments from the automakers, they do not resell our service; rather, automakers facilitate the sale of our service to our customers, acting similar to an agent. We believe this is the appropriate characterization of our relationship since we are responsible for providing service to our customers including being obligated to the customer if there was interruption of service.

Activation fees are recognized ratably over the estimated term of a subscriber relationship, currently estimated to be 3.5 years. The estimated term of a subscriber relationship is based on market research and management’s judgment and, if necessary, will be refined in the future as historical data becomes available.

As required by Emerging Issues Task Force (“EITF”) No. 01-09, “Accounting for Consideration Given by a Vendor to a Customer (Including a Reseller of the Vendor’s Products),” an estimate of mail-in rebates that are paid by us directly to subscribers is recorded as a reduction to revenue in the period the subscriber activates our service. For certain mail-in rebate promotions, a subscriber must remain active for a specified period of time to be considered eligible. In those instances, such estimate is recorded as a reduction to revenue over the required activation period. We estimate the effects of mail-in rebates based on actual take-rates for rebate incentives offered in prior periods, adjusted as deemed necessary based on take-rate data available at the time. In subsequent periods, estimates are adjusted when necessary.

We recognize revenues from the sale of advertising on some of our non-music channels as the advertising is broadcast. Agency fees are calculated based on a stated percentage applied to gross billing revenue for our advertising inventory and are reported as a reduction of advertising revenue. We pay certain third parties a percentage of advertising revenue. Advertising revenue is recorded gross of such revenue share payments in accordance with EITF No. 99-19, “Reporting Revenue Gross as a Principal versus Net as an Agent,” as we are the primary obligor in the transaction. Advertising revenue share is recorded in the period the advertising is broadcast.

Equipment revenue from the direct sale of SIRIUS radios and accessories is recognized upon shipment. Shipping and handling costs billed to customers are recorded as revenue. Shipping and handling costs associated with shipping goods to customers are recorded to cost of equipment.

EITF No. 00-21, “Accounting for Revenue Arrangements with Multiple Deliverables,” provides guidance on how and when to recognize revenues for arrangements that may involve the delivery or performance of multiple products, services and/or rights to use assets. Revenue arrangements with multiple deliverables are required to be divided into separate units of accounting if the deliverables in the arrangement meet certain criteria. Arrangement consideration must be allocated among the separate units of accounting based on their relative fair values.

We determined that the sale of our service through our direct to consumer channel with accompanying equipment constitutes a revenue arrangement with multiple deliverables. In these types of arrangements, amounts received for equipment are recognized as equipment revenue; amounts received for service are recognized as subscription revenue; and amounts received for the non-refundable, up-front activation fee that are not contingent on the delivery of the service are allocated to equipment revenue. Activation fees are recorded to equipment revenue only to the extent that the aggregate equipment and activation fee proceeds do not exceed the fair value of the equipment. Any activation fees not allocated to the equipment are deferred upon activation and recognized as subscriber revenue on a straight-line basis over the estimated term of a subscriber relationship.

Stock-Based Compensation

Effective January 1, 2006, we adopted the provisions of SFAS No. 123 (revised 2004), “Share-Based Payment” (“SFAS No. 123R”), using the modified prospective transition method. The stock-based compensation cost recognized beginning January 1, 2006 includes compensation cost for all stock-based awards granted to

SIRIUS SATELLITE RADIO INC. AND SUBSIDIARIES
NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS - Continued
(Dollar amounts in thousands, unless otherwise stated)
(Unaudited)

employees and members of our board of directors (i) prior to, but not vested as of, January 1, 2006 based on the grant date fair value originally estimated in accordance with the provisions of SFAS No. 123, “Accounting for Stock-Based Compensation,” and (ii) subsequent to December 31, 2005 based on the grant date fair value estimated in accordance with the provisions of SFAS No. 123R.

Compensation cost under SFAS No. 123R is recognized ratably using the straight-line attribution method over the expected vesting period.

SFAS No. 123R requires forfeitures to be estimated on the grant date and revised in subsequent periods if actual forfeitures differ from those estimates. Prior to the adoption of SFAS No. 123R we accounted for forfeitures as they occurred. As of January 1, 2006, the cumulative effect of adopting the estimated forfeiture method was not significant.

Pursuant to SFAS No. 123R, we recognized $15,840 and $32,775, and $18,321 and $40,271 of compensation cost for stock-based awards granted to employees and members of our board of directors for the three and six months ended June 30, 2007 and 2006, respectively. Total unrecognized compensation related to unvested stock-based awards granted to employees and members of our board of directors at June 30, 2007, net of estimated forfeitures, is $104,056 and is expected to be recognized over a weighted-average period of three years.

Effective January 1, 2006, we account for stock-based awards granted to non-employees, other than non-employee members of our board of directors, at fair value in accordance with SFAS No. 123R and SEC guidance contained in Staff Accounting Bulletin (“SAB”) No. 107. The fair value of equity instruments granted to non-employees is measured in accordance with EITF No. 96-18, “Accounting for Equity Instruments That are Issued to Other Than Employees for Acquiring, or in Conjunction with Selling, Goods or Services.” The final measurement date of equity instruments with performance criteria is the date that each performance commitment for such equity instrument is satisfied or there is a significant disincentive for non-performance.

Stock-based awards granted to employees, non-employees and members of our board of directors generally include warrants, stock options, restricted stock and restricted stock units.

We estimate the fair value of stock-based awards using the Black-Scholes option valuation model (“Black-Scholes”). Black-Scholes was developed to estimate the fair market value of traded options, which have no vesting restrictions and are fully transferable. Option valuation models require the input of highly subjective assumptions. Because our stock-based awards have characteristics significantly different from those of traded options and because changes in the subjective assumptions can materially affect the fair market value estimate, existing option valuation models do not necessarily provide a reliable single measure of the fair value of our stock-based awards.

Fair value determined using Black-Scholes varies based on assumptions used for the expected life, expected stock price volatility and risk-free interest rates. For stock-based awards granted prior to 2006, we used historical volatility of our stock over a period equal to the expected life of such awards to estimate their fair value. We estimated the fair value of awards granted since January 1, 2006 using the implied volatility of actively traded options on our stock. We believe that implied volatility is more representative of future stock price trends than historical volatility. The expected life assumption represents the weighted-average period stock-based awards are expected to remain outstanding. These expected life assumptions are established through a review of historical exercise behavior of stock-based award grants with similar vesting periods. Where historical patterns do not exist contractual terms are used. The risk-free interest rate represents the daily treasury yield curve rate at the reporting date based on the closing market bid yields on actively traded U.S. treasury securities in the over-the-counter market for the expected term. Our assumptions may change in future periods.

The following table summarizes the weighted-average assumptions used to compute reported stock-based compensation to employees and members of our board of directors for the periods set forth below:

SFAS No. 123R changes the presentation of realized excess tax benefits associated with the exercise of stock options in the statements of cash flows. Excess tax benefits are realized tax benefits from tax deductions for the exercise of stock options in excess of the deferred tax asset attributable to stock-based compensation expense for such options. Prior to the adoption of SFAS No. 123R, such realized tax benefits were required to be presented as operating cash flows. SFAS No. 123R requires such realized tax benefits to be presented as part of cash flows from financing activities. No income tax benefits have been realized from stock option exercises during the three and six months ended June 30, 2007 and 2006 because a valuation allowance was maintained for all net deferred tax assets.

Subscriber Acquisition Costs

Subscriber acquisition costs include hardware subsidies paid to radio manufacturers, distributors and automakers, including subsidies paid to automakers who include a SIRIUS radio and a prepaid subscription to our service in the sale or lease price of a new vehicle; subsidies paid for chip sets and certain other components used in manufacturing radios; device royalties for certain SIRIUS radios; commissions paid to retailers and automakers as incentives to purchase, install and activate SIRIUS radios; product warranty obligations; provisions for inventory allowance; and compensation costs associated with stock-based awards granted in connection with certain distribution agreements. The majority of subscriber acquisition costs are incurred in advance of acquiring a subscriber. Subscriber acquisition costs do not include advertising, loyalty payments to distributors and dealers of SIRIUS radios and revenue share payments to automakers and retailers of SIRIUS radios. Subscriber acquisition costs also do not include amounts capitalized in connection with our agreement with Hertz, as we retain ownership of certain SIRIUS radios used by Hertz.

Subsidies paid to radio manufacturers and automakers are expensed upon shipment or installation. Commissions paid to retailers and automakers are expensed either upon activation or sale of the SIRIUS radio. Chip sets that are shipped to radio manufacturers and held on consignment are recorded as inventory and expensed as subscriber acquisition costs when placed into production by radio manufacturers. Costs for chip sets not held on consignment are expensed as subscriber acquisition costs when the chip sets are shipped to radio manufacturers.

We record product warranty obligations in accordance with Financial Accounting Standards Board Interpretation (“FIN”) No. 45, “Guarantor’s Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others, an interpretation of FASB Statements No. 5, 57, and 107 and rescission of FASB Interpretation No. 34.” FIN No. 45 requires a guarantor to recognize, at the inception of a guarantee, a liability for the fair value of the obligation undertaken by issuing the guarantee. We warrant that certain products sold through our retail and direct to consumer distribution channels will perform in all material respects in accordance with specifications in effect at the time of the purchase of the products by the customer. We provide a 12-month warranty on our products from purchase date for repair or replacement of components and/or products that contain defects of material or workmanship. Customers may exchange products directly to the retailer within 30 days of purchase. We record a liability for an estimate of costs that we expect to incur under our warranty when the

SIRIUS SATELLITE RADIO INC. AND SUBSIDIARIES

(Dollar amounts in thousands, unless otherwise stated)
(Unaudited)

product is shipped from the manufacturer. Factors affecting our warranty liability include the number of units sold and historical and anticipated rates of claims and costs per claim. We periodically assess the adequacy of our warranty liability based on changes in these factors.

The following table reconciles the beginning and ending aggregate product warranty liability:

Balance, December 31, 2006	$	5,041
Accrual for warranties issued during the period		1,077
Settlements during the period		(2,990	)
Balance, June 30, 2007	$	3,128

Research and Development Costs

Research and development costs are expensed as incurred. Research and development costs for the three months ended June 30, 2007 and 2006 were $10,482 and $9,428, respectively, and $20,532 and $23,856 for the six months ended June 30, 2007 and 2006, respectively. These costs are included in engineering, design and development expenses in our accompanying unaudited consolidated statements of operations.

Income Taxes

We account for income taxes in accordance with SFAS No. 109, “Accounting for Income Taxes” and FIN No. 48, “Accounting for Uncertainty in Income Taxes.” Deferred income taxes are recognized for the tax consequences related to temporary differences between the carrying amount of assets and liabilities for financial reporting purposes and the amounts used for tax purposes at each year-end, based on enacted tax laws and statutory tax rates applicable to the periods in which the differences are expected to affect taxable income. A valuation allowance is established when necessary based on the weight of available evidence, if it is considered more likely than not, that all or some portion of the deferred tax assets will not be realized. Income tax expense is the sum of current income tax plus the change in deferred tax assets and liabilities.

Net (Loss) Income Per Share

We compute net (loss) income per share in accordance with SFAS No. 128, “Earnings Per Share.” Basic net (loss) income per share is calculated using the weighted average common shares outstanding during each reporting period. Diluted net (loss) income per share adjusts the weighted average common shares outstanding for the potential dilution that could occur if common stock equivalents (convertible debt, warrants, stock options and restricted stock units) were exercised or converted into common stock. Common stock equivalents of approximately 164,000,000 and 166,000,000 for the three and six months ended June 30, 2007, respectively, and 190,000,000 and 200,000,000 for the three and six months ended June 30, 2006, respectively, were not considered in the calculation of diluted net loss per share as the effect would have been anti-dilutive.

Inventory

Inventory consists of finished goods, chip sets and other raw material components used in manufacturing radios. Included in our finished goods inventory are certain new products not shipped by our distributor to its customers within 90 days of receipt of goods. Such products are subsequently repurchased by our distributor upon receipt of a customer order.

Inventory is stated at the lower of cost, determined on a first-in, first-out basis, or market. We record an estimated adjustment for inventory that is considered slow moving and obsolete or whose carrying value is in excess of net realizable value. The provision related to product purchased for our direct to consumer distribution channel is recorded to cost of equipment in our unaudited consolidated statements of operations. The remaining provision is recorded to subscriber acquisition costs in our unaudited consolidated statements of operations.

Marketable Securities

We account for marketable securities in accordance with the provisions of SFAS No. 115, “Accounting for Certain Investments in Debt and Equity Securities.” Marketable securities consist of certificates of deposit and auction rate securities. As of June 30, 2007 and December 31, 2006, certificates of deposit were $4,654 and $4,650, respectively, and auction rate securities were $0 and $10,850, respectively. The basic objectives of our investment policy are the preservation of capital, maintaining sufficient liquidity to meet operating requirements and maximizing yield. We classify our marketable securities as available-for-sale securities. Available-for-sale securities are carried at fair market value. Unrealized gains and losses are included in accumulated other comprehensive (loss) income as a separate component of stockholders’ equity. Realized gains and losses, dividends and interest income, including amortization of the premium and discount arising at purchase, are included in interest and investment income. The specific-identification method is used to determine the cost of all securities and the basis by which amounts are reclassified from accumulated comprehensive (loss) income into earnings. While the underlying securities of auction rate securities have contractual maturities of more than 20 years, the interest rates on such securities reset at intervals of 28 or 35 days. Auction rate securities are priced and trade as short-term investments because of such interest rate reset feature.

We received proceeds from the sale or maturity of marketable securities of $10,846, and $177,125 for the six months ended June 30, 2007 and 2006, respectively. There were no unrealized holding gains or losses on marketable securities as of June 30, 2007 and December 31, 2006.

Restricted Investments

As of June 30, 2007 and December 31, 2006, short-term restricted investments of $25,310 and $25,000, respectively, primarily included certificates of deposit placed in escrow for the benefit of a third party pursuant to a programming agreement.

As of June 30, 2007 and December 31, 2006, long-term restricted investments of $52,850 primarily included certificates of deposit and money market funds deposited in escrow for the benefit of third parties pursuant to programming agreements and certificates of deposit placed in escrow to secure our reimbursement obligations under letters of credit issued for the benefit of lessors of office space.

Investment, stated at cost

In September 2006, we invested in a third party for strategic purposes. We account for this investment under the cost method. The carrying value of our investment was $5,000 at June 30, 2007 and December 31, 2006 and is included in other long-term assets in our accompanying unaudited consolidated balance sheet.

Equity Method Investment

We have a 49.9% economic interest in SIRIUS Canada. Our investment in SIRIUS Canada is recorded using the equity method since we have significant influence, but less than a controlling voting interest. Under this method, our investment in SIRIUS Canada, originally recorded at cost, is adjusted to recognize our share of net earnings or losses as they occur rather than as dividends or other distributions are received, limited to the extent of our investment in, advances to and commitments to fund SIRIUS Canada. Our share of net earnings or losses of SIRIUS Canada is recorded to equity in net loss of affiliate in our accompanying unaudited consolidated statements of operations. We recorded $0 for both the three months ended June 30, 2007 and 2006, and $0 and $4,445 for the six months ended June 30, 2007 and 2006, respectively, for our share of SIRIUS Canada’s net loss.

Merger Costs

We have incurred approximately $19,000 in direct costs for the six months ended June 30, 2007 in connection with our pending merger with XM Radio. In accordance with SFAS No. 141, “Business Combinations,” which specifies that the cost of an entity acquired in a business combination include the direct costs of the business combination, we have capitalized and included such costs in other long-term assets in our accompanying unaudited consolidated balance sheet.

Reclassifications

Certain amounts in the prior period unaudited consolidated financial statements have been reclassified to conform to the current period presentation. Specifically, during the first quarter of 2007, we reclassified both broadcast and webstreaming royalties from programming and content expenses; revenue share from programming and content expenses and sales and marketing expenses; and residuals from sales and marketing expenses to a separate line item, revenue share and royalties. In addition, we reclassified bad debt expense from general and administrative expenses to customer service and billing expenses.

Recent Accounting Pronouncements

In September 2006, the FASB issued SFAS No. 157, “Fair Value Measurements,” which defines fair value, establishes a framework for measuring fair value and expands the related disclosure requirements. SFAS No. 157 is effective for fiscal years beginning after November 15, 2007 and for interim periods within those years. We are currently evaluating the impact of the adoption, if any, that SFAS No. 157 will have on our consolidated results of operations and financial position.

In September 2006, the FASB issued EITF No. 06-01, “Accounting for Consideration Given by a Service Provider to Manufacturers or Resellers of Equipment Necessary for an End-Customer to Receive Service from the Service Provider.” The EITF concluded that if consideration given by a service provider to a third-party manufacturer or reseller that is not the service provider’s customer can be linked contractually to the benefit received by the service provider’s customer, a service provider should account for the consideration in accordance with EITF No. 01-09, “Accounting for Consideration Given by a Vendor to a Customer.” EITF No. 06-01 is effective for annual reporting periods beginning after June 15, 2007. We are currently evaluating the effects that EITF No. 06-01 will have on our consolidated results of operations and financial position.

In February 2007, the FASB issued SFAS No. 159, “The Fair Value Option for Financial Assets and Financial Liabilities,” which permits entities to choose to measure many financial instruments and certain other items at fair value. The objective of SFAS No. 159 is to provide entities a method to mitigate volatility in reporting earnings caused by measuring related assets and liabilities differently without having to apply complex hedge accounting provisions. SFAS No. 159 is effective for annual reporting periods beginning after November 15, 2007. We are currently evaluating the effects that SFAS No. 159 will have on our consolidated results of operations and financial position.

4. Subscriber Revenue

Subscriber revenue consists of subscription fees, revenue derived from our agreement with Hertz, non-refundable activation fees and the effects of mail-in rebates. Revenues received from automakers for prepaid subscriptions included in the sale or lease price of a new vehicle are also included in subscriber revenue over the service period upon activation and sale to the customer.

6. Related Party Transactions

In 2005, we entered into a license and services agreement with SIRIUS Canada. Pursuant to such agreement, we are reimbursed for certain costs incurred by us to provide SIRIUS Canada service, including certain costs we incur for the production and distribution of radios as well as information technology support costs. In consideration for the rights granted pursuant to this license and services agreement, SIRIUS Canada pays us a royalty based on a percentage of its annual gross revenues. Additionally, the initial financing we provided to SIRIUS Canada is by way of subscription to non-voting shares which carry an 8% cumulative dividend.

Total costs reimbursed by SIRIUS Canada for the three months ended June 30, 2007 and 2006 were $723 and $1,521, respectively, and $2,600 and $4,087 for the six months ended June 30, 2007 and 2006, respectively. We recorded $643 and $203 in royalty income for the three months ended June 30, 2007 and 2006, respectively, and $1,159 and $306 for the six months ended June 30, 2007 and 2006, respectively.

Space Systems/Loral Credit Agreement

In June 2006, we entered into a Credit Agreement with Space Systems/Loral (the “Loral Credit Agreement”). Under the Loral Credit Agreement, Space Systems/Loral has agreed to make loans to us in an aggregate principal amount of up to $100,000 to finance the purchase of our fifth satellite. Loans made under the Loral Credit Agreement will be secured by our rights under the Satellite Purchase Agreement with Space Systems/Loral, including our rights to this satellite. The loans are also entitled to the benefits of a subsidiary guarantee from Satellite CD Radio, Inc., our subsidiary that holds our FCC license, and any future material subsidiary that may be formed by us. The maturity date of the loans is the earliest to occur of (i) April 6, 2009, (ii) 90 days after this satellite becomes available for shipment and (iii) 30 days prior to the scheduled launch of this satellite. Any loans made under the Loral Credit Agreement generally will bear interest at a variable rate equal to three-month LIBOR plus 4.75%. The daily unused balance bears interest at a rate per annum equal to 0.50%, payable quarterly on the last day of each March, June, September and December. The Loral Credit Agreement permits us to prepay all or a portion of the loans outstanding without penalty. We have not borrowed under this Credit Agreement as of June 30, 2007.

Covenants and Restrictions

Our 9⁵/8% Senior Notes due 2013, our Loral Credit Agreement and our Senior Secured Term Loan require us to comply with certain covenants that restrict our ability to, among other things, (i) incur additional indebtedness, (ii) incur liens, (iii) pay dividends or make certain other restricted payments, investments or acquisitions, (iv) enter into certain transactions with affiliates, (v) merge or consolidate with another person, (vi) sell, assign, lease or otherwise dispose of all or substantially all of our assets, and (vii) make voluntary prepayments of certain debt, in each case subject to exceptions as provided in the 9⁵/8% Senior Notes due 2013 indenture, the Loral Credit Agreements and the credit agreement governing our Senior Secured Term Loan. If we fail to comply with these covenants, our 9⁵/8% Senior Notes due 2013, our Senior Secured Term Loan and any loans outstanding under the Loral Credit Agreement could become immediately payable and the Loral Credit Agreement could be terminated. At June 30, 2007, we were in compliance with all such covenants.

9. Benefit Plans

Stock-Based Awards

In January 2003, our board of directors adopted the Sirius Satellite Radio 2003 Long-Term Stock Incentive Plan (the “2003 Plan”), and on March 4, 2003 our stockholders approved this plan. On May 25, 2004, our stockholders approved an amendment to the 2003 Plan to include members of our board of directors as eligible participants. Employees, consultants and members of our board of directors are eligible to receive awards under the 2003 Plan. The 2003 Plan provides for the grant of stock options, restricted stock, restricted stock units and other stock-based awards that the compensation committee of our board of directors may deem appropriate.

Vesting and other terms of stock-based awards are set forth in the agreements with the individuals receiving the awards. Stock-based awards granted under the 2003 Plan are generally subject to a vesting requirement that includes one or all of the following: (1) over time, generally three to five years from the date of grant; (2) on a specific date in future periods, with acceleration to earlier periods if performance criteria are satisfied; or (3) as certain performance targets set at the time of grant are achieved. Stock-based awards generally expire ten years from the date of grant. Each restricted stock unit entitles the holder to receive one share of our common stock upon vesting.

401(k) Savings Plan

We sponsor the Sirius Satellite Radio 401(k) Savings Plan (the “Plan”) for eligible employees. The Plan allows eligible employees to voluntarily contribute from 1% to 50% of their pre-tax salary subject to certain defined limits. Currently we match 50% of employee voluntary contributions, up to 6% of an employee’s pre-tax salary, in the form of shares of our common stock. Our matching contribution vests at a rate of 33¹/3% for each year of

SIRIUS SATELLITE RADIO INC. AND SUBSIDIARIES

(Dollar amounts in thousands, unless otherwise stated)
(Unaudited)

employment and is fully vested after three years of employment. Expense resulting from our matching contribution to the Plan was $295 and $338 for the three months ended June 30, 2007 and 2006, respectively, and $793 and $750 for the six months ended June 30, 2007 and 2006, respectively.

We may also elect to contribute to the profit sharing portion of the Plan based upon the total compensation of all eligible participants. These additional contributions, referred to as profit-sharing contributions, are determined by the compensation committee of our board of directors. Employees are only eligible to receive profit-sharing contributions during any year in which they are employed on the last day of the year. Profit-sharing contribution expense was $1,412 and $953 for the three months ended June 30, 2007 and 2006, respectively, and $2,763 and $2,259 for the six months ended June 30, 2007 and 2006, respectively.

10. Income Taxes

We recorded income tax expense of $555 and $578 for the three months ended June 30, 2007 and 2006, respectively, and $1,110 and $1,331 for the six months ended June 30, 2007 and 2006, respectively. Such expense represents the recognition of a deferred tax liability related to the difference in accounting for our FCC license, which is amortized over 15 years for tax purposes but not amortized for book purposes.

We adopted the provisions of FIN No. 48 on January 1, 2007. FIN No. 48 prescribes a recognition threshold and measurement attributes for financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return, as well as criteria on derecognition, measurement, classification, interest and penalties, accounting in interim periods, disclosure and transition. The cumulative effect of applying this interpretation did not result in any adjustment to retained earnings as of January 1, 2007.

We provide a valuation allowance for all of our deferred tax assets. Accordingly, unrecognized federal or state income tax positions should not impact the face of our financial statements, but instead would reduce the gross tax benefit. We did not have any unrecognized tax benefits.

We have elected to record interest accrued related to unrecognized tax benefits as interest expense and penalties as operating expense. As of June 30, 2007, we recorded no interest expense or penalties related to unrecognized tax benefits. As of June 30, 2007, we are subject to examination in the United States federal and various state tax jurisdictions for the 2003 to 2006 tax years.

11. Commitments and Contingencies

Debt Obligations. Debt obligations include principal payments on our outstanding debt.

Cash Interest Payments. Cash interest payments include interest due on our outstanding debt through maturity.

Lease Obligations. We have entered into operating leases related to our studios, office space, terrestrial repeaters and equipment.

Satellite and Transmission. We have entered into agreements with third parties to operate and maintain our off-site satellite telemetry, tracking and control facilities and certain components of our terrestrial repeater network.

(Dollar amounts in thousands, unless otherwise stated)
(Unaudited)

We have also entered into an agreement with Space Systems/Loral to design and construct a new satellite. Construction of this satellite is expected to be completed in the fourth quarter of 2008. We plan to launch this satellite on a Proton rocket under our contract with International Launch Services.

Programming and Content. We have entered into agreements with licensors of programming and other content providers and, in certain instances, are obligated to pay license fees and guarantee minimum advertising revenue share. In addition, we have agreements with various rights organizations pursuant to which we pay royalties for public performances of music.

Customer Service and Billing. We have entered into agreements with third parties to provide billing and subscriber management services.

Marketing and Distribution. We have entered into various marketing, sponsorship and distribution agreements to promote our brand and are obligated to make payments to sponsors, retailers, automakers and radio manufacturers under these agreements. Certain programming and content agreements also require us to purchase advertising on properties owned or controlled by the licensors. We also reimburse automakers for certain engineering and development costs associated with the incorporation of SIRIUS radios into vehicles they manufacture. In addition, in the event that certain new products are not shipped by our distributor to its customers within 90 days of their receipt of goods, we have agreed to purchase and take title to the product.

Chip Set Development and Production. We have entered into agreements with third parties to develop, produce and supply chip sets; to develop products; and in certain instances to license intellectual property related to chip sets.

Other. We have entered into various agreements with third parties for general operating and strategic purposes.

In addition to the contractual cash commitments described above, we have entered into agreements with automakers, radio manufacturers and others that include per-radio, per-subscriber, per-show and other variable cost arrangements. These future costs are dependent upon many factors including our subscriber growth and are difficult to anticipate; however, these costs may be substantial. We may enter into additional programming, distribution, marketing and other agreements that contain similar provisions.

Under the terms of a joint development agreement with XM Radio, the other holder of a FCC satellite radio license, each party is obligated to fund one half of the development cost for a unified standard for satellite radios. The costs related to the joint development agreement are being expensed as incurred to engineering, design and development expense in the accompanying unaudited consolidated statements of operations. We are currently unable to determine the expenditures necessary to complete this process, but we do not expect that these expenditures will be material.

We are required under the terms of certain agreements to provide letters of credit and deposit monies in escrow, which place restrictions on our cash and cash equivalents. As of June 30, 2007 and December 31, 2006, $78,160 and $77,850, respectively, was classified as restricted investments as a result of our reimbursement obligations under these letters of credit and escrow deposits.

As of June 30, 2007, we have not entered into any off-balance sheet arrangements or transactions.

Legal Proceedings

FCC Inquiry. In April 2006, we learned that XM Radio and two manufacturers of SIRIUS radios had received inquiries from the FCC as to whether the FM transmitters in their products complied with the FCC’s emissions and frequency rules. We promptly began an internal review of the compliance of the FM transmitters in a number of our radios. In June 2006, we learned that a third manufacturer of SIRIUS radios had received an inquiry from the FCC as to whether the FM transmitters in its products complied with the FCC’s emissions and frequency rules. In June 2006, we received a letter from the FCC making similar inquiries. In July 2006, we responded to the letter from the FCC in respect of the preliminary results of our review. In August 2006, we received a follow-up letter of inquiry from the FCC and responded to the FCC’s further inquiry. We continue to cooperate with the FCC’s inquiry.

During our internal review, we determined that certain of our radios with FM transmitters were not compliant with FCC rules. We have taken a series of actions to correct the problem.

SIRIUS SATELLITE RADIO INC. AND SUBSIDIARIES
NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS - Continued
(Dollar amounts in thousands, unless otherwise stated)
(Unaudited)

In connection with our internal review, we discovered that certain SIRIUS personnel requested manufacturers to produce SIRIUS radios that were not consistent with the FCC’s rules. As a result of this review, we are taking significant steps to ensure that this situation does not happen again, including the adoption of a compliance plan, approved by our board of directors, to ensure that in the future our products comply with all applicable FCC rules.

The FCC’s laboratory has tested a number of our products and found them to be compliant with the FCC’s rules. We believe our radios that are currently in production comply with applicable FCC’s rules. No health or safety issues are involved with these SIRIUS radios and radios which are factory-installed in new vehicles are not affected.

We have retained an engineering compliance officer to report to our Vice President of Internal Audit, who reports to our Audit Committee.

In October 2006, we ceased operating 11 of our terrestrial repeaters which we discovered had been operating at variance to the specifications and applied to the FCC for new authority to resume operating these repeaters.

Copyright Royalty Board Proceeding. We are a party to a proceeding before the Copyright Royalty Board of the Library of Congress to establish the royalty rates and terms for the sound recordings we use on our satellite radio service for the period for 2007 through 2012 In June 2007, the hearing before the Copyright Royalty Board commenced, with both us and XM and SoundExchange, the organization that collects and distributes royalties for digital music services on behalf of artists and music labels, presenting evidence in support of their direct cases. In July 2007, we, XM and SoundExchange filed our rebuttal cases in this proceeding; and in August 2007, the Copyright Royalty Board will convene a hearing to permit the parties to present rebuttal evidence.

As part of this proceeding, we originally proposed a royalty rate of 0.89% of our satellite subscription revenue. We have filed an amended rate proposal requesting the Copyright Royalty Board to establish a royalty rate for calendar year 2007 of $1.20 for each performance we make of a copyrighted sound recording. We have also proposed that this royalty rate be adjusted each subsequent year by a percentage equal to the percentage change in aggregate satellite radio subscribers during the preceding year. SoundExchange has proposed a royalty rate consisting of the greater of a specified percentage of revenue or a per-subscriber fee. The SoundExchange proposed fees would increase as our number of subscribers increase, in seven steps that start at the greater of 8% of total revenues or $0.85 per subscriber per month, if we have fewer than 9 million subscribers, and end at the greater of 23% of total revenue or $3.00 per subscriber per month, if we have more than 19 million subscribers. SoundExchange has also proposed, as an alternative that it describes as less-preferred, a per-broadcast fee structure, which it claims is calculated to reach similar fee levels if we continue with our current level of music performances.

The Copyright Royalty Board must set a rate that is calculated to achieve four statutory objectives:

	•	to maximize the availability of creative works to the public;

	•	to afford the copyright owner a fair return for his creative work and the copyright user a fair income under existing economic conditions;

	•	to reflect the relative roles of the copyright owner and the copyright user in the product made available to the public with respect to relative creative contribution, technological contribution, capital investment, cost, risk and contribution to the opening of new markets for creative expression and media for their communication; and

	•	to minimize any disruptive impact on the structure of the industries involved and on generally prevailing industry practices.

We believe that the fee we proposed achieves these objectives. We expect the Copyright Royalty Board to render a decision establishing a rate for the sound recordings we use on our satellite radio service by the end of 2007.

U.S. Electronics Arbitration. U.S. Electronics Inc., a licensed distributor and a former licensed manufacturer of SIRIUS radios, has commenced an arbitration proceeding against us. U.S. Electronics alleges that we breached our contract; failed to pay monies owed under the contract; tortiously interfered with U.S. Electronics’ relationships with retailers and manufacturers; withheld information relating to the FCC’s inquiring into SIRIUS radios that include FM modulators; and otherwise acted in bad faith. U.S. Electronics is seeking at least $48,000 in damages. We believe that a substantial portion of these damages are barred by the limitation of liability provisions contained in the contract between us and U.S. Electronics. U.S. Electronics contends, and will be permitted to try to

SIRIUS SATELLITE RADIO INC. AND SUBSIDIARIES
NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS - Continued
(Dollar amounts in thousands, unless otherwise stated)
(Unaudited)

prove in the arbitration, that these provisions do not bar its damages because of, among other reasons, our alleged bad faith and tortious conduct. We are vigorously defending this action.

Other Matters. In the ordinary course of business, we are a defendant in various lawsuits and arbitration proceedings, including actions filed by former employees, parties to contracts or leases and owners of patents, trademarks, copyrights or other intellectual property. None of these actions are, in our opinion, likely to have a material adverse effect on our business or financial position and statements of operation.

12. Subsequent Events

We exercised an option under our existing satellite purchase agreement with Space Systems/Loral, Inc. to purchase our sixth satellite. Space Systems/Loral will design and construct the satellite, which is expected to be one of the most advanced and powerful satellites ever built.

Construction of this satellite is expected to be completed in 2010. The satellite is expected to be launched into an inclined elliptical orbit to complement our existing satellites, which were also manufactured by Space Systems/Loral. Our unique hybrid constellation, consisting of satellites operating in a highly inclined geosynchronous orbits in combination with one satellite operating in a geostationary orbit will provide unparalleled redundancy, enhanced coverage and exceptional performance.

The aggregate cost of designing and building this satellite will be approximately $169,000. A substantial portion of this purchase price will not be paid until 2009 and following the launch and successful completion of on-orbit testing of this satellite.

In June 2006, in connection with the contract to purchase our fifth satellite, which is currently under construction, Space Systems/Loral agreed to provide us a $100,000 vendor financing facility. No amounts in connection with this existing facility have been drawn. As part of the exercise of the option to purchase an additional satellite, Space Systems/Loral has amended and extended this $100,000 vendor financing to permit us to access the facility to pay a portion of the purchase price of the new satellite.

Item 2.

Management’s Discussion and Analysis of Financial Condition and Results of Operations
(All dollar amounts are in thousands, unless otherwise stated)

Special Note Regarding Forward-Looking Statements

The following cautionary statements identify important factors that could cause our actual results to differ materially from those projected in forward-looking statements made in this Quarterly Report on Form 10-Q and in other reports and documents published by us from time to time. Any statements about our beliefs, plans, objectives, expectations, assumptions, future events or performance are not historical facts and may be forward-looking. These statements are often, but not always, made through the use of words or phrases such as “will likely result,” “are expected to,” “will continue,” “is anticipated,” “estimated,” “intend,” “plan,” “projection” and “outlook.” Any forward-looking statements are qualified in their entirety by reference to the factors discussed throughout our Annual Report on Form 10-K for the year ended December 31, 2006 (the “Form 10-K”) and in other reports and documents published by us from time to time, particularly the risk factors described under “Business—Risk Factors” in Item 1A of the Form 10-K.

Among the significant factors that could cause our actual results to differ materially from those expressed in the forward-looking statements are:

	•	our pending merger with XM Satellite Radio Holdings Inc. (“XM Radio”), including related uncertainties and risks and the impact on our business if the merger is not completed;

	•	the useful life of our satellites, which have experienced circuit failures on their solar arrays and other component failures and are not insured;

	•	our dependence upon third parties, including manufacturers of SIRIUS radios, retailers, automakers and programming providers; and

	•	our competitive position versus other forms of audio and video entertainment, including terrestrial radio, HD radio, internet radio, digital music recorders, XM Radio and emerging next generation networks and technologies.

Because the risk factors referred to above could cause actual results or outcomes to differ materially from those expressed in any forward-looking statements made by us or on our behalf, you should not place undue reliance on any of these forward-looking statements. In addition, any forward-looking statement speaks only as of the date on which it is made, and we undertake no obligation to update any forward-looking statement or statements to reflect events or circumstances after the date on which the statement is made, to reflect the occurrence of unanticipated events or otherwise. New factors emerge from time to time, and it is not possible for us to predict which will arise or to assess with any precision the impact of each factor on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements.

Executive Summary

On February 19, 2007, we and XM Radio entered into an Agreement and Plan of Merger (the “Merger Agreement”), pursuant to which we and XM Radio will combine our businesses through a merger of XM Radio and a newly formed, wholly owned subsidiary of us (the “Merger”). Our Board of Directors and the Board of Directors of XM Radio have approved the Merger and the Merger Agreement.

The completion of the Merger is subject to various closing conditions, including obtaining the approval of our stockholders and XM Radio’s stockholders and receiving certain regulatory and antitrust approvals (including from the FCC and under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended). The information presented in this Quarterly Report on Form 10-Q does not give effect to the Merger.

We broadcast through our proprietary satellite radio system, which currently consists of three orbiting satellites, 124 terrestrial repeaters that receive and retransmit our signal, a satellite uplink facility and our studios. Subscribers receive our service through SIRIUS radios, which are sold by automakers, consumer electronics retailers and mobile audio dealers and through our website. Subscribers can also receive our music channels and certain other channels over the Internet.

In 2005, SIRIUS Canada Inc., a Canadian corporation owned by us, Canadian Broadcasting Corporation and Standard Broadcasting Corporation, received a license from the Canadian Radio-television and Telecommunications Commission to offer a satellite radio service in Canada. SIRIUS Canada offers 110 channels of commercial-free music and news, sports, talk and entertainment programming, including 11 channels of Canadian content. Subscribers to the SIRIUS Canada service are not included in our subscriber count.

SIRIUS radios are primarily distributed through retailers; automakers, or OEMs; and through our website. SIRIUS radios can be purchased at major retailers, including Best Buy; Circuit City; Crutchfield; Costco; Target; Wal-Mart; and on an exclusive basis through RadioShack. On June 30, 2007, SIRIUS radios were available at more than 20,000 retail locations. We have exclusive agreements with DaimlerChrysler, Ford, Kia, Mitsubishi, BMW, Rolls-Royce, Volkswagen and Bentley to offer SIRIUS radios as factory or dealer-installed equipment. We also have relationships with Nissan, Infiniti, Toyota, Lexus, Scion and Subaru to offer SIRIUS radios as factory or dealer-installed equipment. As of June 30, 2007, SIRIUS radios were available as a factory-installed option in 119 vehicle models and as a dealer-installed option in 31 vehicle models. SIRIUS radios are also offered to renters of Hertz vehicles at airport locations nationwide.

As of June 30, 2007, we had 7,142,538 subscribers compared with 6,024,555 subscribers as of December 31, 2006 and 4,678,207 subscribers as of June 30, 2006. Our subscriber totals include subscribers under our regular pricing plans; subscribers that have prepaid, including payments received from automakers for prepaid subscriptions included in the sale or lease price of a new vehicle; active SIRIUS radios under our agreement with Hertz; and subscribers to SIRIUS Internet Radio, our Internet service.

We believe our ability to attract and retain subscribers depends in large part on creating and sustaining distribution channels for SIRIUS radios, the strength of the SIRIUS brand, and on the quality and entertainment value of our programming. We expect to concentrate our future efforts on enhancing and refining our programming, whether through additional agreements with third parties or our own creative efforts; introducing SIRIUS radios with new features and functions; and expanding the distribution of SIRIUS radios through arrangements with automakers and through additional retail points-of-sale.

Our primary source of revenue is subscription fees, with most of our customers subscribing to SIRIUS on either an annual or a monthly basis. We offer discounts for prepaid and long-term subscriptions as well as discounts for multiple subscriptions. Currently we receive an average of approximately eight months of prepaid revenue per subscriber upon activation. We also derive revenue from activation fees, the sale of advertising on our non-music channels and the direct sale of SIRIUS radios and accessories.

In certain cases, automakers include a subscription to our radio service in the sale or lease price of vehicles. The length of these prepaid subscriptions varies, but is typically six months to one year. In many cases, we receive subscription payments from automakers in advance of the activation of our service. We also reimburse various automakers for certain costs associated with SIRIUS radios installed in their vehicles.

Costs associated with acquiring subscribers are generally incurred and expensed in advance of acquiring a subscriber and are recognized as subscriber acquisition costs, or SAC. A disproportionate percentage of our annual gross subscriber additions are acquired in the fourth quarter in connection with holiday sales. As a result, our SAC, as adjusted, per gross subscriber addition, a key operating metric for our business, is generally higher in the first three quarters of our fiscal year and declines in the fourth quarter as we experience higher activation rates.

Pending Merger with XM Radio

On February 19, 2007, we entered into an Agreement and Plan of Merger with XM Radio Holdings Inc. Pursuant to the Merger Agreement, we and XM Radio will combine our businesses through a merger of XM Radio and a newly formed, wholly owned subsidiary of ours.

Each of SIRIUS and XM has made customary representations and warranties and covenants in the Merger Agreement. The completion of the Merger is subject to various closing conditions, including obtaining approvals of certain of our and XM Radio’s stockholders and receiving certain regulatory and antitrust approvals (including from the FCC and under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended). The Merger is intended to qualify as a reorganization for federal income tax purposes.

At the effective time of the Merger (the “Effective Time”), by virtue of the Merger and without any action on the part of any stockholder, each share of common stock of XM Radio (the “XM Common Stock”) issued and outstanding immediately prior to the Effective Time will generally be converted into the right to receive 4.6 shares of our common stock. Each share of Series A Convertible Preferred Stock of XM Radio issued and outstanding immediately prior to the Effective Time will be similarly converted at the Effective Time into the right to receive 4.6 shares of a newly-designated series of our preferred stock having substantially the same powers, designations, preferences, rights and qualifications, limitations and restrictions as the stock so converted.

Mel Karmazin, our chief executive officer, will become chief executive officer of the combined company and Gary M. Parsons, chairman of the board of directors of XM Radio, will become chairman of the board of directors of the combined company. The combined company’s board of directors will consist of 12 directors, including Messrs. Karmazin and Parsons, four independent members designated by each of SIRIUS and XM Radio, as well as one representative of each of General Motors and American Honda.

The Merger Agreement contains certain termination rights for both us and XM Radio. If the Merger Agreement is terminated under certain circumstances specified in the Merger Agreement, we or XM Radio, as the case may be, will be required to pay the other a termination fee of $175,000.

Our Board of Directors and the Board of Directors of XM Radio have approved the Merger and the Merger Agreement.

This description of the Merger Agreement does not purport to be complete and is qualified in its entirety by reference to the Merger Agreement, which is filed as Exhibit 2.1 to our Current Report on Form 8-K dated February 21, 2007.

Results of Operations

Our discussion of our results of operations, along with the selected financial information in the tables that follow, includes the following non-GAAP financial measures: average monthly churn; average monthly revenue per subscriber, or ARPU; SAC, as adjusted, per gross subscriber addition; customer service and billing expenses, as adjusted, per average subscriber; free cash flow; and adjusted loss from operations. We believe these non-GAAP financial measures provide meaningful supplemental information regarding our operating performance and are used for internal management purposes, when publicly providing the business outlook, and as a means to evaluate period-to-period comparisons. Please refer to the footnotes following our discussion of results of operations for the definitions and further discussion of usefulness of such non-GAAP financial measures.

Certain amounts in the prior period unaudited consolidated financial statements have been reclassified to conform to the current period presentation. Specifically, during the first quarter 2007, we reclassified both broadcast and webstreaming royalties from programming and content expenses; revenue share from programming and content expenses and sales and marketing expenses; and residuals from sales and marketing expenses to a separate line item, revenue share and royalties. In addition, we reclassified bad debt expense from general and administrative expenses to customer service and billing expenses.

Subscribers. We ended the second quarter of 2007 with 7,142,538 subscribers, an increase of 19% since December 31, 2006 and 53% from the 4,678,207 subscribers as of June 30, 2006. Since June 30, 2006, we added 1,088,031 net subscribers from our retail channel and 1,385,029 net subscribers from our OEM channel, resulting in a 33% and 101% increase in our retail and OEM subscriber base, respectively.

The following table presents our key operating metrics for the past five quarters:

	For the Three Months Ended

ARPU. Total ARPU for the three months ended June 30, 2007 was $10.71 compared to $11.16 for the three months ended June 30, 2006. The decrease was primarily driven by a decline in net advertising revenue per average subscriber and the impact of plan mix due in part to the increase in subscribers under multi-unit subscription plans, offset by the effects of mail-in rebates resulting from lower eligible activations. At June 30, 2007, approximately two thirds of our subscribers were on an annual or longer subscription plan and approximately 18% were paying $6.99 per month under a multi-unit subscriber plan, as compared to 13% at June 30, 2006.

We expect ARPU to fluctuate based on the growth of our subscriber base, promotions, mail-in rebates offered to subscribers and corresponding take-rates, plan mix, subscription prices, advertising sales and the identification of additional revenue streams from subscribers.

SAC, As Adjusted, Per Gross Subscriber Addition. SAC, as adjusted, per gross subscriber addition was $108 and $131 for the three months ended June 30, 2007 and 2006, respectively. The decline was primarily attributable to lower OEM costs per unit offset by a higher mix of OEM gross additions.

We expect SAC, as adjusted, per gross subscriber addition to decline as the costs of subsidized components of SIRIUS radios decrease in the future. If competitive forces or changes in retailer promotional strategies,

including the elimination of mail-in rebates by retailers, require us to increase hardware subsidies or promotions, SAC, as adjusted, per gross subscriber addition may increase. Our SAC, as adjusted, per gross subscriber addition is generally higher in the first three quarters of our fiscal year and declines in the fourth quarter as we experience higher activation rates.

Customer Service and Billing Expenses, As Adjusted, Per Average Subscriber Per Month. Customer service and billing expenses, as adjusted, per average subscriber per month declined 13% to $1.05 for the second quarter of 2007 compared with $1.20 for the second quarter of 2006.

We expect customer service and billing expenses, as adjusted, per average subscriber to decrease on an annual basis as our subscriber base grows due to scale efficiencies in call center and other customer care and billing operations. Our customer service and billing expenses, as adjusted, per average subscriber are generally lower in the first three quarters of our fiscal year and increase in the fourth quarter due to the holiday selling season.

Adjusted Loss from Operations. For the three months ended June 30, 2007 and 2006, adjusted loss from operations was $79,299 and $126,528, respectively, a decrease of $47,229. The decrease was primarily driven by an increase in total revenue of $76,349 as a result of a 53% increase in our subscriber base, which more than offset increases in expenses of $29,120.

Net Loss. For the three months ended June 30, 2007 and 2006, net loss was $134,147 and $237,828, respectively, a decrease of $103,681. The decrease was primarily driven by an increase in total revenue of $76,349 as a result of a 53% increase in our subscriber base and a decrease in stock-based compensation as a result of certain performance targets satisfied in 2006.

Three and Six Months Ended June 30, 2007 Compared with Three and Six Months Ended June 30, 2006

Total Revenue

Subscriber Revenue. Subscriber revenue includes subscription fees, activation fees and the effects of mail-in rebates.

	•	Three Months: For the three months ended June 30, 2007 and 2006, subscriber revenue was $209,635 and $137,641, respectively, an increase of 52% or $71,994. The increase was attributable to the growth of subscribers to our service.

	•	Six Months: For the six months ended June 30, 2007 and 2006, subscriber revenue was $400,431 and $252,822, respectively, an increase of 58% or $147,609. The increase was attributable to the growth of subscribers to our service.

The following table contains a breakdown of our subscriber revenue for the periods presented:

	For the Three Months						For the Six Months
	Ended June 30,						Ended June 30,
	2007			2006			2007			2006
Subscription fees	$	205,486		$	136,025		$	395,455		$	254,016
Activation fees		4,849			3,647			10,168			7,371
Effect of mail-in rebates		(700	)		(2,031	)		(5,192	)		(8,565	)
Total subscriber revenue	$	209,635		$	137,641		$	400,431		$	252,822

Future subscriber revenue will be dependent upon, among other things, the growth of our subscriber base, promotions, mail-in rebates offered to subscribers and corresponding take-rates, plan mix, subscription prices and the identification of additional revenue streams from subscribers.

Advertising Revenue. Advertising revenue includes the sale of advertising on our non-music channels, net of agency fees. Agency fees are based on a stated percentage per the advertising agreements applied to gross billing revenue.

	•	Three Months: For the three months ended June 30, 2007 and 2006, net advertising revenue was $9,177 and $8,125, respectively, an increase of $1,052.

	•	Six Months: For the six months ended June 30, 2007 and 2006, net advertising revenue was $15,898 and $15,463, respectively, an increase of $435.

We expect advertising revenue to grow as our subscribers increase, as we continue to improve brand awareness and content, and as we increase the size and effectiveness of our advertising sales force. Advertising revenue is also subject to fluctuation based on the overall advertising environment.

Equipment Revenue. Equipment revenue includes revenue from the direct sale of SIRIUS radios and accessories through our direct to consumer distribution channel.

	•	Three Months: For the three months ended June 30, 2007 and 2006, equipment revenue was $6,255 and $3,096, respectively, an increase of $3,159. The increase was the result of higher sales through our direct to consumer distribution channel, offset by the effects of promotional discounts.

	•	Six Months: For the six months ended June 30, 2007 and 2006, equipment revenue was $10,926 and $6,788, respectively, an increase of $4,138. The increase was the result of higher sales through our direct to consumer distribution channel, offset by the effects of promotional discounts.

We expect equipment revenue to increase as we continue to introduce new products and as sales grow through our direct to consumer distribution channel.

Operating Expenses

Satellite and Transmission. Satellite and transmission expenses consist of costs associated with the operation and maintenance of our satellites; satellite telemetry, tracking and control system; terrestrial repeater network; satellite uplink facility; and broadcast studios.

	•	Three Months: For the three months ended June 30, 2007 and 2006, satellite and transmission expenses were $7,337 and $18,496, respectively, a decrease of $11,159. Excluding stock-based compensation of $621 and $810 for the three months ended June 30, 2007 and 2006, respectively, satellite and transmission expenses decreased $10,970 from $17,686 to $6,716. The second quarter of 2006 included a $10,900 non-recurring impairment charge associated with certain satellite long-lead time parts that were no longer needed. As of June 30, 2007 and 2006, we had 124 and 139 terrestrial repeaters, respectively, in operation.

	•	Six Months: For the six months ended June 30, 2007 and 2006, satellite and transmission expenses were $15,323 and $26,699, respectively, a decrease of $11,376. Excluding stock-based compensation of $1,277 and $1,712 for the six months ended June 30, 2007 and 2006, respectively, satellite and transmission expenses decreased $10,941 from $24,987 to $14,046. The second quarter of 2006 included a $10,900 non-recurring impairment charge associated with certain satellite long-lead time parts that were no longer needed.

Future increases in satellite and transmission expenses will primarily be attributable to the launch and operation of new satellites, the addition of new terrestrial repeaters and maintenance costs of existing terrestrial repeaters. We expect to deploy additional terrestrial repeaters in 2007 and 2008 subject to obtaining necessary regulatory approvals. Such expenses may also increase in future periods if we decide to reinstate our in-orbit satellite insurance.

Programming and Content. Programming and content expenses include costs to acquire, create and produce content and on-air talent costs. We have entered into various agreements with third parties for music and non-music programming. These agreements require us to pay license fees, share advertising revenue, purchase advertising on media properties owned or controlled by the licensor and pay other guaranteed amounts. Purchased advertising is recorded as a sales and marketing expense in the period the advertising is broadcast. Advertising revenue share is recorded to revenue share and royalties also in the period the advertising is broadcast.

	•	Three Months: For the three months ended June 30, 2007 and 2006, programming and content expenses were $54,311 and $68,622, respectively, a decrease of $14,311. Excluding stock-based compensation of $1,215 and $23,724 for the three months ended June 30, 2007 and 2006, respectively, programming and content expenses increased $8,198 from $44,898, to $53,096. This increase of $8,198 was primarily attributable to license fees associated with new programming. Stock-based compensation decreased $22,509 as compared to second quarter 2006 primarily due to expense

		associated with shares of our common stock delivered to Howard Stern and his agent in 2006 upon the satisfaction of performance targets.

	•	Six Months: For the six months ended June 30, 2007 and 2006, programming and content expenses were $114,309 and $368,356, respectively, a decrease of $254,047. Excluding stock-based compensation of $4,150 and $273,524 for the six months ended June 30, 2007 and 2006, respectively, programming and content expenses increased $15,327 from $94,832, to $110,159. This increase of $15,327 was primarily attributable to license fees associated with new programming and compensation related costs for additions to headcount. Stock-based compensation decreased $269,374 primarily due to expense associated with shares of our common stock delivered to Howard Stern and his agent in January 2006 upon the satisfaction of performance targets.

Our programming and content expenses, excluding stock-based compensation expense, will increase as we continue to develop and enhance our channels. We regularly evaluate programming opportunities and may choose to acquire and develop new content or renew current programming agreements in the future at substantial costs.

Future expense associated with stock-based compensation is contingent upon a number of factors, including the number of stock-based awards granted, the price of our common stock, assumptions used in estimating the fair value of stock-based awards, estimates for forfeitures, vesting provisions and the timing as to when certain performance criteria are met, and could materially change.

Revenue Share and Royalties. Revenue share and royalties include distribution and content provider revenue share, residuals and broadcast and webstreaming royalties. Residuals are monthly fees paid based upon the number of subscribers using a SIRIUS radio purchased from a retailer. Advertising revenue share is recorded to revenue share and royalties in the period the advertising is broadcast.

	•	Three Months: For the three months ended June 30, 2007 and 2006, revenue share and royalties were $29,841 and $16,958, respectively, an increase of $12,883. This increase was primarily attributable to the growth in our revenue as well as an increase in our OEM subscriber base.

	•	Six Months: For the six months ended June 30, 2007 and 2006, revenue share and royalties were $56,975 and $30,485, respectively, an increase of $26,490. This increase was primarily attributable to the growth in our revenue as well as an increase in our OEM subscriber base.

We expect revenue share to increase as we continue to experience revenue growth and expand our distribution of SIRIUS radios through automakers. In addition, we expect broadcast and webstreaming royalties, which are typically variable in nature, to increase as our subscriber base grows. We are currently a party to a proceeding before the Copyright Royalty Board of the Library of Congress to establish the royalty rate and terms for the sound recordings we use on our satellite radio service for the period 2007 through 2012. We expect a decision by the end of 2007.

Customer Service and Billing. Customer service and billing expenses include costs associated with the operation of our customer service centers and subscriber management system as well as bad debt expense.

	•	Three Months: For the three months ended June 30, 2007 and 2006, customer service and billing expenses were $21,618 and $15,866, respectively, an increase of $5,752. Excluding stock-based compensation of $178 and $204 for the three months ended June 30, 2007 and 2006, respectively, customer service and billing expenses increased $5,778 from $15,662 to $21,440. This increase of $5,778 was primarily due to higher call center operating costs necessary to accommodate the increase in the our subscriber base and higher total transaction fees on the larger base. Customer service and billing expenses, excluding stock-based compensation, increased 37% compared with an increase in subscribers of 53% year over year.

	•	Six Months: For the six months ended June 30, 2007 and 2006, customer service and billing expenses were $43,471 and $33,728, respectively, an increase of $9,743. Excluding stock-based compensation of $377 and $448 for the three months ended June 30, 2007 and 2006, respectively, customer service and billing expenses increased $9,814 from $33,280 to $43,094. This increase of $9,814 was primarily due to higher call center operating costs necessary to accommodate the increase in our subscriber base and higher total transaction fees on the larger base. Customer service and billing expenses, excluding

stock-based compensation, increased 29% compared with an increase in subscribers of 53% year over year.

We expect our customer care and billing expenses, excluding stock-based compensation expense, to increase as our subscriber base grows due to increased call center operating costs, transaction fees necessary to serve a larger subscriber base and bad debt expense.

Cost of Equipment. Cost of equipment includes costs for SIRIUS radios and accessories sold through our direct to consumer distribution channel.

	•	Three Months: For the three months ended June 30, 2007 and 2006, cost of equipment was $8,636 and $3,467, respectively, an increase of $5,169. The increase was primarily attributable to higher sales volume, offset by a decline in per unit costs.

	•	Six Months: For the six months ended June 30, 2007 and 2006, cost of equipment was $17,928 and $6,932, respectively, an increase of $10,996. The increase was primarily attributable to higher sales volume, offset by a decline in per unit costs. In addition, we recorded a $2,782 inventory allowance in the six months ended June 30, 2007 primarily as a result of lower of cost or market adjustments and reserves for slow moving inventory.

We expect cost of equipment to increase in the future as we introduce new products and as sales through our direct to consumer distribution channel grow.

Sales and Marketing. Sales and marketing expenses include costs for advertising, media and production, including promotional events and sponsorships; cooperative marketing; customer retention and compensation. Cooperative marketing costs include fixed and variable payments to reimburse retailers and automakers for the cost of advertising and other product awareness activities.

	•	Three Months: For the three months ended June 30, 2007 and 2006, sales and marketing expenses were $45,614 and $52,831, respectively, a decrease of $7,217. Excluding stock-based compensation of $2,849 and $5,067 for the three months ended June 30, 2007 and 2006, respectively, sales and marketing expenses decreased $4,999 from $47,764 to $42,765. This decrease was primarily attributable to lower consumer advertising and reduced cooperative marketing spend with our distributors.

	•	Six Months: For the six months ended June 30, 2007 and 2006, sales and marketing expenses were $83,776 and $87,312, respectively, an decrease of $3,536. Excluding stock-based compensation of $8,493 and $7,269 for the six months ended June 30, 2007 and 2006, respectively, sales and marketing expenses decreased $4,760 from $80,043 to $75,283. This $4,760 decrease was primarily attributable to lower consumer advertising and reduced cooperative marketing spend with our distributors.

We expect sales and marketing expenses, excluding stock-based compensation expense, to increase as we continue to build brand awareness through national advertising and promotional activities and expand our subscriber retention efforts.

Subscriber Acquisition Costs. Subscriber acquisition costs include hardware subsidies paid to radio manufacturers, distributors and automakers, including subsidies paid to automakers who include a SIRIUS radio and a prepaid subscription to our service in the sale or lease price of a new vehicle; subsidies paid for chip sets and certain other components used in manufacturing radios; device royalties for certain SIRIUS radios; commissions paid to retailers and automakers as incentives to purchase, install and activate SIRIUS radios; product warranty obligations; provisions for inventory allowance; and compensation costs associated with stock-based awards granted in connection with certain distribution agreements. The majority of subscriber acquisition costs are incurred and expensed in advance of acquiring a subscriber. Subscriber acquisition costs do not include advertising, loyalty payments to distributors and dealers of SIRIUS radios and revenue share payments to automakers and retailers of SIRIUS radios. Subscriber acquisition costs also do not include amounts capitalized in connection with our agreement with Hertz, as we retain ownership of certain SIRIUS radios used by Hertz.

	•	Three Months: For the three months ended June 30, 2007 and 2006, subscriber acquisition costs were $105,665 and $130,563, respectively, a decrease of 19% or $24,898. Excluding stock-based compensation of $7 and $21,900 for the three months ended June 30, 2007 and 2006, respectively, subscriber acquisition costs decreased 3%, or $3,005, from $108,663 to $105,658. This decrease of $3,005 was primarily attributable to lower aftermarket subsidies, offset by increased OEM hardware subsidies due to higher production volume. Stock-based compensation decreased $21,893 primarily due to the timing of third parties achieving milestones and changes in the fair market value of such awards.

	•	Six Months: For the six months ended June 30, 2007 and 2006, subscriber acquisition costs were $205,782 and $249,606, respectively, a decrease of 18% or $43,824. Excluding stock-based compensation of $1,887 and $31,799 for the six months ended June 30, 2007 and 2006, respectively, subscriber acquisition costs decreased 6%, or $13,912, from $217,807 to $203,895. This decrease of $13,912 was primarily attributable to lower aftermarket subsidies, offset by increased OEM hardware subsidies due to higher production volume. Stock-based compensation decreased $29,912 primarily due to the timing of third parties achieving milestones and changes in the fair market value of such awards.

We expect total subscriber acquisition costs, excluding stock-based compensation expense, to decrease as increases in our gross subscriber additions are offset by continuing declines in the costs of subsidized components of SIRIUS radios. We intend to continue to offer subsidies, commissions and other incentives to acquire subscribers.

General and Administrative. General and administrative expenses include rent and occupancy, finance, legal, human resources, information technology and investor relations costs.

	•	Three Months: For the three months ended June 30, 2007 and 2006, general and administrative expenses were $38,471 and $32,555, respectively, an increase of $5,916. Excluding stock-based compensation of $11,163 and $12,905 for the three months ended June 30, 2007 and 2006, respectively, general and administrative expenses increased $7,658 from $19,650 to $27,308. This increase of $7,658 was primarily the result of higher legal fees and compensation-related costs to support the growth of our business. Stock-based compensation decreased $1,742 primarily as a result of restricted stock units that vested in the second quarter of 2006.

	•	Six Months: For the six months ended June 30, 2007 and 2006, general and administrative expenses were $73,814 and $64,428, respectively, an increase of $9,386. Excluding stock-based compensation of $23,103 and $27,411 for the six months ended June 30, 2007 and 2006, respectively, general and administrative expenses increased $13,694 from $37,017 to $50,711. This increase of $13,694 was primarily a result of higher legal fees and compensation-related costs to support the growth of our business. Stock-based compensation decreased $4,308 primarily as a result of restricted stock units that vested in 2006.

We expect our general and administrative expenses, excluding stock-based compensation expense, to increase in future periods as a result of higher personnel, information technology, and facilities costs, as well as increased legal fees to support the growth of our business.

Engineering, Design and Development. Engineering, design and development expenses include costs to develop our future generation of chip sets and new products and costs associated with the incorporation of SIRIUS radios into vehicles manufactured by automakers.

	•	Three Months: For the three months ended June 30, 2007 and 2006, engineering, design and development expenses were $11,250 and $15,454, respectively, a decrease of $4,204. Excluding stock-based compensation of $984 and $2,679 for the three months ended June 30, 2007 and 2006,

		respectively, engineering, design and development expenses decreased $2,509 from $12,775 to $10,266. This decrease of $2,509 was primarily attributable to reduced OEM tooling and manufacturing upgrades associated with the factory installation of SIRIUS radios in additional vehicle models. Stock-based compensation decreased $1,695 primarily due to the timing of third parties achieving certain production milestones.

	•	Six Months: For the six months ended June 30, 2007 and 2006, engineering, design and development expenses were $23,661 and $35,166, respectively, a decrease of $11,505. Excluding stock-based compensation of $1,990 and $9,712 for the six months ended June 30, 2007 and 2006, respectively, engineering, design and development expenses decreased $3,783 from $25,454 to $21,671. This decrease of $3,783 was primarily attributable reduced OEM tooling and manufacturing upgrades associated with the factory installation of SIRIUS radios in additional vehicle models. Stock-based compensation decreased $7,722 primarily due to the timing of third parties achieving certain production milestones.

We expect engineering, design and development expenses, excluding stock-based compensation expense, to decrease, as the work required to initially incorporate SIRIUS radios and accessories in a significant number of additional vehicle models was completed in 2006.

Other Income (Expense)

Interest and Investment Income. Interest and investment income includes realized gains and losses, dividends and interest income, including amortization of the premium and discount arising at purchase.

	•	Three Months: For the three months ended June 30, 2007 and 2006, interest and investment income was $4,753 and $8,873, respectively, a decrease of $4,120. The decrease was attributable to a lower average cash balance.

	•	Six Months: For the six months ended June 30, 2007 and 2006, interest and investment income was $10,795 and $18,810, respectively, a decrease of $8,015. The decrease was attributable to a lower average cash balance.

Interest Expense. Interest expense includes interest on outstanding debt, reduced by interest capitalized in connection with the construction of our new satellite and launch vehicle.

	•	Three Months: For the three months ended June 30, 2007 and 2006, interest expense was $15,750 and $15,660, respectively, an increase of $90. Interest expense was consistent with second quarter 2006 given debt levels remained consistent with the second quarter of 2006 prior to the incurrence of the $250,000 Senior Secured Term Loan in June 2007. Interest expense was offset by the capitalized interest associated with satellite construction and the related launch vehicle.

	•	Six Months: For the six months ended June 30, 2007 and 2006, interest expense was $30,942 and $32,784, respectively, a decrease of $1,842. The decrease was primarily the result of capitalized interest in 2007 associated with satellite construction and the related launch vehicle, which was offset by the interest expense associated with the new term loan.

Equity in Net Loss of Affiliate. Equity in net loss of affiliate includes our share of SIRIUS Canada’s net loss.

We recorded $0 and $4,445 for the six months ended June 30, 2007 and 2006, respectively, for our share of SIRIUS Canada’s net loss.

As of June 30, 2007, our investment in SIRIUS Canada was $0 as we fully recognized our share of SIRIUS Canada’s net loss to the extent we have funded it. We do not expect to recognize future net losses unless we commit to additional funding.

Income Taxes

Income Tax Expense. Income tax expense represents the recognition of a deferred tax liability related to the difference in accounting for our FCC license, which is amortized over 15 years for tax purposes but not amortized for book purposes in accordance with U.S. generally accepted accounting principles.

	•	Three Months: We recorded income tax expense of $555 and $578 for the three months ended June 30, 2007 and 2006, respectively.

	•	Six Months: We recorded income tax expense of $1,110 and $1,331 for the six months ended June 30, 2007 and 2006, respectively.

Footnotes to Results of Operations

(1)	Average monthly churn represents the number of deactivated subscribers divided by average quarterly subscribers.

(2)	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:

(6)	Average monthly churn; 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 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.

(7)	We refer 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 U.S. GAAP. We believe adjusted loss from operations is a useful measure of our operating performance. We use adjusted 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 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 loss from operations to estimate our current or prospective enterprise value and 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 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 expense 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. 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 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. Finally, we believe that the exclusion of our equity in net loss of affiliate (SIRIUS Canada Inc.) is useful to assess the performance of our 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, we separately measure and budget for these items.

	There are material limitations associated with the use of adjusted 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, impairment charges and stock-based compensation expense. We use 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 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 loss from operations is a non-GAAP financial measure, our 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 prepared in accordance with GAAP.

Adjusted loss from operations is calculated as follows:

In the first quarter of 2007, SIRIUS reclassified both broadcast and webstreaming royalties from programming and content expenses; revenue share from programming and content expenses and sales and marketing expenses; and residuals from sales and marketing expenses to a separate line item, revenue share and royalties. In addition, SIRIUS reclassified bad debt expense from general and administrative expenses to customer service and billing expenses. Certain amounts in the prior period annual and quarterly consolidated financial statements have been reclassified to conform to the current period presentation. Included above are the GAAP condensed consolidated statements of operations for 2006 that reflects these reclassifications.

Liquidity and Capital Resources

Cash Flows for the Six Months Ended June 30, 2007 Compared with the Six Months Ended June 30, 2006

As of June 30, 2007, we had $424,749 in cash and cash equivalents compared with $534,963 as of June 30, 2006 and $393,421 as of December 31, 2006.

The following table presents a summary of our cash flow activity for the periods set forth below:

	For the Six Months
	Ended June 30,
	2007			2006			Variance

Cash and cash equivalents at end of period	$	424,749		$	534,963		$	(110,214	)

Net Cash Used in Operating Activities

Net cash used in operating activities decreased $76,240 to $189,847 for the six months ended June 30, 2007 from $266,087 for the six months ended June 30, 2006. Such decrease in the net outflows of cash was attributable to increased cash receipts from subscribers due to the growth of our subscriber base, offset by an increase in paydown of distribution accruals and stock-based compensation expense to third parties in 2006 as a result of certain targets that were satisfied.

Net Cash Used in Investing Activities

Net cash used in investing activities was $25,956 for the six months ended June 30, 2007 compared with net cash provided by investing activities of $36,067 for the six months ended June 30, 2006. The $62,023 decrease was primarily a result of higher net sales activity of available-for-sale securities in the second quarter of 2006, offset by an increase in capital expenditures of $8,809 primarily as a result of costs associated with our satellite construction and launch vehicle.

We will incur significant capital expenditures to construct and launch our new satellites and to improve our terrestrial repeater network and broadcast and administrative infrastructure. These capital expenditures will support our growth and the resiliency of our operations, and will also support the delivery of future new revenue streams.

Net Cash Provided by Financing Activities

Net cash provided by financing activities increased $244,155 to $247,131 for the six months ended June 30, 2007 from $2,976 for the six months ended June 30, 2006. The increase was a result of additional debt proceeds, net of related costs of $245,199 from the new term loan entered into in June 2007.

Financings and Capital Requirements

We have historically financed our operations through the sale of debt and equity securities.

Future Liquidity and Capital Resource Requirements

Based upon our current plans, we believe that our cash, cash equivalents and marketable securities will be sufficient to cover our estimated funding needs through cash flow breakeven, the point at which our revenues are sufficient to fund expected operating expenses, capital expenditures, working capital requirements, interest and principal payments and taxes. In light of our pending merger with XM Radio, and the uncertainty surrounding the timing and financial impact, we are no longer currently providing cash flow guidance for the year ending December 31, 2007 or beyond. Our financial projections are based on assumptions, which we believe are reasonable but contain significant uncertainties.

Our business is in its early stages, and we regularly evaluate our plans and strategy. These evaluations often result in changes to our plans and strategy, some of which may be material and significantly change our cash requirements or cause us to achieve cash flow breakeven at a later date. These changes in our plans or strategy may include: the acquisition of unique or compelling programming; the introduction of new features or services;

significant new or enhanced distribution arrangements; investments in infrastructure, such as satellites, equipment or radio spectrum; and acquisitions of third parties that own programming, distribution, infrastructure, assets, or any combination of the foregoing.

In June 2006, we entered into a Credit Agreement with Space Systems/Loral (the “Credit Agreement”). Under the Credit Agreement, Space Systems/Loral has agreed to make loans to us in an aggregate principal amount of up to $100,000 to finance the purchase of our new satellite. Loans made under the Credit Agreement will be secured by our rights under the Satellite Purchase Agreement with Space Systems/Loral, including our rights to the new satellite. The loans are also entitled to the benefits of a subsidiary guarantee from Satellite CD Radio, Inc., our subsidiary that holds our FCC license, and any future material subsidiary that may be formed by us. The maturity date of the loans is the earliest to occur of (i) April 6, 2009, (ii) 90 days after the new satellite becomes available for shipment, and (iii) 30 days prior to the scheduled launch of the new satellite. Any loans made under the Credit Agreement generally will bear interest at a variable rate equal to three-month LIBOR plus 4.75% . The Credit Agreement permits us to prepay all or a portion of the loans outstanding without penalty. We have no current plans to draw under this Credit Agreement.

In June 2007, we entered into a Term Credit Agreement with a syndicate of financial institutions. The Credit Agreement provides for a term loan of $250,000, which has been drawn. Interest under the Credit Agreement is based, at our option, on (i) adjusted LIBOR plus 2.25% or (ii) the higher of (a) the prime rate and (b) the Federal Funds Effective Rate plus 1/2 of 1.00%, plus 1.25%. LIBOR borrowings may be made for interest periods, at our option, of one, two, three or six months (or, if agreed by all of the lenders, nine or twelve months). The loan amortizes in equal quarterly installments of 0.25% of the initial aggregate principal amount for the first four and a half years, with the balance of the loan thereafter being repaid in four equal quarterly installments. The loan matures on December 20, 2012. The loan is guaranteed by our wholly owned subsidiary, Satellite CD Radio, Inc. (the “Guarantor”). The Credit Agreement is secured by a lien on substantially all of our and the Guarantor’s assets, including our satellites and the shares of the Guarantor. The Credit Agreement contains customary affirmative covenants and event of default provisions. The negative covenants contained in the Credit Agreement are substantially similar to those contained in the indenture governing our 9⁵/₈% Senior Notes due 2013.

To fund incremental cash requirements, or as market opportunities arise, we may choose to raise additional funds through the sale of additional debt securities, equity securities or a combination of debt and equity securities. The incurrence of additional indebtedness would result in increased fiscal obligations and could contain restrictive covenants. The sale of additional equity or convertible debt securities may result in dilution to our stockholders. These additional sources of funds may not be available or, if available, may not be available on terms favorable to us. Our merger agreement with XM Radio restricts our ability to incur additional debt financing beyond our existing credit facilities (or equivalent funding) and limits the amount of new equity we can issue, in each case without approval from XM Radio.

2003 Long-Term Stock Incentive Plan

Vesting and other terms of stock-based awards are set forth in the agreements with the individuals receiving the awards. Stock-based awards granted under the 2003 Plan are generally subject to a vesting requirement that includes one or all of the following: (1) over time, generally three to five years from the date of grant; (2) on a specific date in future periods, with acceleration to earlier periods if performance criteria are satisfied; or (3) as certain performance targets set at the time of grant are achieved. Stock-based awards generally expire ten years from date of grant. Each restricted stock unit entitles the holder to receive one share of our common stock upon vesting.

As of June 30, 2007, approximately 86,563,000 stock options, shares of restricted stock and restricted stock units were outstanding. As of June 30, 2007, approximately 72,996,000 shares of our common stock were available for grant under the 2003 Plan. During the six months ended June 30, 2007, employees exercised 556,236 stock options at exercise prices ranging from $2.81 to $4.16 per share, resulting in proceeds to us of $757. The exercise of the remaining outstanding, vested options could result in an inflow of cash in future periods.

Contractual Cash Commitments

For a discussion of our “Contractual Cash Commitments” refer to Note 11 to the unaudited consolidated financial statements, Commitments and Contingencies, of this Form 10-Q.

Critical Accounting Policies

For a description of our Critical Accounting Policies refer to “Management’s Discussion and Analysis of Financial Condition and Results of Operations” within our Annual Report on Form 10-K for the year ended December 31, 2006 and Note 3 to the unaudited consolidated financial statements, Summary of Significant Accounting Policies, of this Form 10-Q.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

As of June 30, 2007, we did not have any derivative financial instruments and we do not intend to use derivatives. We do not hold or issue any free-standing derivatives. We hold investments in marketable securities, which consist of certificates of deposit and auction rate securities. We classify our marketable securities as available-for-sale. These securities are consistent with the investment objectives contained within our investment policy. The basic objectives of our investment policy are the preservation of capital, maintaining sufficient liquidity to meet operating requirements and maximizing yield. Despite the underlying long-term maturity of auction rate securities, from the investor’s perspective, such securities are priced and trade as short-term investments because of the interest rate reset feature. Interest rates are reset through an auction process at predetermined periods of 28 or 35 days. Failed auctions rarely occur. As of June 30, 2007, we did not hold any auction rate securities.

Our long-term debt includes fixed interest rates and the fair market value of the debt is sensitive to changes in interest rates. Under our current policies, we do not use interest rate derivative instruments to manage our exposure to interest rate fluctuations.

Item 4. Controls and Procedures

As of June 30, 2007, an evaluation was performed under the supervision and with the participation of our management, including Mel Karmazin, our Chief Executive Officer, and David J. Frear, our Executive Vice President and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures. Based on that evaluation, our management, including our Chief Executive Officer and our Chief Financial Officer, concluded that our disclosure controls and procedures were effective as of June 30, 2007. There have been no significant changes in our internal control over financial reporting or in other factors that could materially affect, or is reasonably likely to materially affect, our internal control over financial reporting for the three months ended June 30, 2007.

Item 1. Legal Proceedings

During our internal review, we determined that certain of our radios with FM transmitters were not compliant with FCC rules. We have taken a series of actions to correct the problem.

We have retained an engineering compliance officer to report to our Vice President of Internal Audit, who reports to our Audit Committee.

Copyright Royalty Board Proceeding. We are a party to a proceeding before the Copyright Royalty Board of the Library of Congress to establish the royalty rates and terms for the sound recordings we use on our satellite radio service for the period for 2007 through 2012. In June 2007, the hearing before the Copyright Royalty Board commenced, with both us and XM and SoundExchange, the organization that collects and distributes royalties for digital music services on behalf of artists and music labels, presenting evidence in support of their direct cases. In July 2007, we, XM and SoundExchange filed our rebuttal cases in this proceeding; and in August 2007, the Copyright Royalty Board will convene a hearing to permit the parties to present rebuttal evidence.

The Copyright Royalty Board must set a rate that is calculated to achieve four statutory objectives:

	•	to maximize the availability of creative works to the public;

	•	to afford the copyright owner a fair return for his creative work and the copyright user a fair income under existing economic conditions;

	•	to reflect the relative roles of the copyright owner and the copyright user in the product made available to the public with respect to relative creative contribution, technological contribution, capital investment, cost, risk and contribution to the opening of new markets for creative expression and media for their communication; and

	•	to minimize any disruptive impact on the structure of the industries involved and on generally prevailing industry practices.
