1. Business

Sirius Satellite Radio Inc. broadcasts over 110 channels of digital-quality entertainment: over 60 channels of 100% commercial-free music and over 50 channels of news, sports, talk, entertainment, traffic, weather and children’s programming for an effective monthly subscription fee of $11.15 for a three year plan and up to $12.95 for a monthly plan. We offer discounts for pre-paid and long-term subscriptions as well as discounts for multiple subscriptions. Approximately 68% of our new subscribers acquired during the three months ended March 31, 2004 purchased an annual subscription with an effective monthly subscription fee of $11.87.

Since inception, we have used substantial resources to develop our satellite radio system. Our satellite radio system consists of our FCC license, satellite system, national broadcast studio, terrestrial repeater network and satellite telemetry, tracking and control facilities. On July 1, 2002, we launched our service nationwide.

As of March 31, 2004, we had 351,663 subscribers. Our subscriber totals included subscribers currently in promotional periods and those which have prepaid, and active SIRIUS radios under our agreement with Hertz.

Our primary sources of revenue are subscription and activation fees. In addition, we derive revenues from selling advertising on our non-music channels and from the direct sale of SIRIUS radios.

2. Principles of Consolidation and Basis of Presentation

The accompanying unaudited consolidated financial statements, including the accounts of Sirius Satellite Radio Inc. and our wholly owned subsidiary, have been prepared in accordance with accounting principles generally accepted in the United States 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 accounting principles generally accepted in the United States for complete financial statements. All intercompany transactions have been eliminated in consolidation.

In the opinion of management, all adjustments (consisting only of normal, recurring adjustments) considered necessary for a fair presentation of the consolidated financial statements as of March 31, 2004 and December 31, 2003, and for the three months ended March 31, 2004 and 2003, have been recorded. The results of operations for the three months ended March 31, 2004 are not necessarily indicative of the results that may be expected for the full year. Our consolidated financial statements should be read together with our consolidated financial statements and the notes thereto contained in our Annual Report on Form 10-K for the year ended December 31, 2003.

3. Summary of Significant Accounting Policies

Revenue Recognition

Revenue from subscribers consists of subscription fees, including revenue derived from our agreement with Hertz, and non-refundable activation fees. We recognize subscription fees as our service is provided. We record deferred revenue for prepaid subscription fees and amortize these prepayments to revenue ratably over the term of the subscription plan. Activation fees are recognized ratably over the estimated term of a subscriber relationship, currently 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 additional historical data becomes available. We record an estimate of mail-in rebates that are paid by us directly to subscribers as a reduction to subscription revenue in the period the subscriber activates our service. In subsequent periods, estimates are adjusted when necessary.

We recognize revenues from the sale of advertising on 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.

Equipment revenue from the direct sale of SIRIUS radios is recognized upon shipment of the radios.

Stock-Based Compensation

In accordance with Accounting Principles Board (“APB”) Opinion No. 25, “Accounting for Stock Issued to Employees,” we use the intrinsic value method to measure the compensation costs of stock-based awards granted to employees. Accordingly, we record non-cash compensation expense for stock-based awards granted to employees and directors over the vesting period equal to the excess of the market price of the underlying common stock at the date of grant over the exercise price of the stock-based award. The intrinsic value of restricted stock units as of the date of grant is amortized to non-cash stock compensation expense over the vesting period. To the extent any performance criteria are satisfied and the vesting of any stock options and/or restricted stock units accelerate, the unamortized non-cash stock compensation expense associated with these options or restricted stock units is also accelerated.

We account for stock-based awards granted to non-employees at fair value in accordance with Statement of Financial Accounting Standards (“SFAS”) No. 123, “Accounting for Stock-Based Compensation.”

In accordance with Financial Accounting Standards Board (“FASB”) Interpretation No. 44, “Accounting for Certain Transactions Involving Stock Compensation,” we record compensation charges or benefits related to repriced stock options based on the market value of our common stock until the repriced stock options are exercised, forfeited or expire.

In accordance with Emerging Issues Task Force 96-18, “Accounting for Equity Instruments That Are Issued to Other Than Employees for Acquiring, or in Conjunction with Selling, Goods or Services,” we record expense based upon performance and the fair value of equity instruments issued to other than employees at each reporting date. The final measurement date of equity instruments is the date that each performance commitment for such equity instrument is satisfied. These costs are classified in our accompanying statements of operations according to the nature of the services performed.

We have adopted the disclosure provisions of SFAS No. 148, “Accounting for Stock-Based Compensation—Transition and Disclosure—An Amendment of FASB Statement No. 123.” The following table illustrates the effect on net (loss) income applicable to common stockholders and net loss per share applicable to common stockholders had stock-based employee compensation been recorded based on the fair value method under SFAS No. 123:

	For the Three Months Ended March 31,
	2004			2003

Net (loss) income applicable to common stockholders—as reported	$	(144,059	)	$	51,880
Non-cash stock compensation expense—as reported		8,065			559
Stock-based compensation—pro forma		(16,449	)		(7,718	)
Net (loss) income applicable to common stockholders—pro forma	$	(152,443	)	$	44,721
Net (loss) income per share applicable to common stockholders:
Basic—as reported	$	(0.12	)	$	0.16
Diluted—as reported	$	(0.12	)	$	0.16
Net (loss) income per share applicable to common stockholders:
Basic—pro forma	$	(0.13	)	$	0.14
Diluted—pro forma	$	(0.13	)	$	0.14

The measure of fair value most often employed under SFAS No. 123, and used by us, is the Black-Scholes option valuation model (“Black-Scholes”). Black-Scholes has become the standard for estimating the fair value of traded options. Traded options, unlike our stock-based awards, are not subject to vesting restrictions, are fully transferable and use significantly lower expected stock price volatility measures than those assumed below. It is our opinion that this model (and other similar option valuation models) does not produce a single reliable measure of the

SIRIUS SATELLITE RADIO INC. AND SUBSIDIARY
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — CONTINUED
(Dollar amounts in thousands, unless otherwise stated)
(Unaudited)

fair value of our stock-based awards. The pro forma stock-based employee compensation was estimated using Black-Scholes with the following assumptions for each period:

	For the Three Months Ended March 31,
	2004		2003
Risk-free interest rate	2.98	%	1.87	%
Expected life of options—years	5.30		4.89
Expected stock price volatility	114	%	115	%
Expected dividend yield	0	%	0	%

Debt Restructuring

We recorded a gain of $256,538 in connection with the restructuring of our long-term debt in March 2003. This gain represents the difference between the carrying value of our 15% Senior Secured Discount Notes due 2007, 14½% Senior Secured Notes due 2009, Lehman term loans and Loral term loans, including accrued interest, and the fair market value of the common stock issued, adjusted for unamortized debt issuance costs and direct costs associated with the restructuring. This gain is net of a loss on our 8¾% Convertible Subordinated Notes due 2009 exchanged in the restructuring. This loss represents the difference between the fair market value of the common stock issued in the exchange and the fair market value of the common stock which would have been issued under the original conversion ratio, including accrued interest, adjusted for unamortized debt issuance costs and direct costs associated with the restructuring.

Preferred Stock Deemed Dividend

We recorded a deemed dividend of $79,510 in connection with the exchange in March 2003 of all outstanding shares of our preferred stock for shares of our common stock and warrants to purchase our common stock. This deemed dividend represents the difference between the fair market value of the common stock and warrants issued in exchange for all outstanding shares of our 9.2% Series A Junior Cumulative Convertible Preferred Stock, 9.2% Series B Junior Cumulative Convertible Preferred Stock and 9.2% Series D Junior Cumulative Convertible Preferred Stock and the fair market value of the common stock which would have been issued under the original conversion ratios, adjusted for unamortized issuance costs and direct costs associated with the exchange of the preferred stock.

Net (Loss) Income Per Share

Basic net (loss) income per share is based on the weighted average common shares outstanding during each reporting period. Diluted net (loss) income per share adjusts the weighted average 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 194,000,000 and 11,000,000 were not considered in the calculation of diluted net (loss) income per share for the three months ended March 31, 2004 and 2003, respectively, as the effect would have been anti-dilutive.

Comprehensive Income (Loss)

We report comprehensive income (loss) in accordance with SFAS No. 130, “Reporting Comprehensive Income.” SFAS 130 established a standard for reporting and displaying other comprehensive income (loss) and its components within financial statements. Unrealized gains and losses on available-for-sale securities are the only components of our other comprehensive (loss) income. Comprehensive (loss) income for the three months ended March 31, 2004 and 2003 was $(144,078) and $139,344, respectively.

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 U.S. government notes and

SIRIUS SATELLITE RADIO INC. AND SUBSIDIARY
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — CONTINUED
(Dollar amounts in thousands, unless otherwise stated)
(Unaudited)

U.S. government agency obligations and are classified as available-for-sale securities. Available-for-sale securities are carried at fair market value and unrealized gains and losses are included as a component of stockholders’ equity. We recognized gains on the sale or maturity of marketable securities of $76 and $979 for the three months ended March 31, 2004 and 2003, respectively. Marketable securities held at March 31, 2004 and December 31, 2003 mature within one year from the date of purchase. We had unrealized holding gains on marketable securities of $7 and $26 as of March 31, 2004 and December 31, 2003, respectively.

Restricted Investments

Restricted investments consist of fixed income securities, which are stated at amortized cost plus accrued interest. As of March 31, 2004 and December 31, 2003, long-term restricted investments included certificates of deposit of $6,750. Long-term restricted investments as of March 31, 2004 also included $85,000 deposited in escrow in connection with our NFL agreement. This deposit is invested under our direction in a commercial money market fund and will be drawn by the NFL to pay the rights fees due for the 2006-2009 NFL seasons. As of March 31, 2004 and December 31, 2003, short-term restricted investments included certificates of deposit and United States government obligations of $366 and $1,997, respectively. The certificates of deposit and United States government obligations are pledged to secure our reimbursement obligations under letters of credit issued primarily for the benefit of the lessor of our headquarters.

Asset Retirement Obligation

In accordance with SFAS No. 143, “Accounting for Asset Retirement Obligations,” we recorded costs equal to the present value of the future obligation associated with the retirement of our terrestrial repeater network. These costs, which are included in other long-term liabilities, include an amount that we estimate will be sufficient to satisfy our obligations under leases to remove our terrestrial repeater equipment and restore the sites to their original condition. As of March 31, 2004 and December 31, 2003, our asset retirement obligation was $295 and $279, respectively.

Reclassifications

Certain amounts in the prior period consolidated financial statements have been reclassified to conform to the current period presentation.

4. Subscriber Revenue

Subscriber revenue consists of subscription revenue, non-refundable activation revenue and the effects of mail-in rebate programs. An estimate of mail-in rebates that are paid by us directly to subscribers are recorded as a reduction to subscriber revenue in the period the subscriber activates service. In subsequent periods estimates are adjusted when necessary. Subscriber revenue consists of the following:

	For the Three Months Ended March 31,
	2004			2003
Subscription revenue	$	9,859		$	1,523
Activation revenue		404			43
Effects of mail-in rebates		(1,061	)		(12	)
Total subscriber revenue, including effects of mail-in rebates	$	9,202		$	1,554

5. Non-Cash Stock Compensation

We record non-cash stock compensation expense or benefit in connection with the grant of certain stock options and restricted stock units, and the issuance of common stock to employees and employee benefit plans. We recognized non-cash stock compensation expense of $8,065 and $559 for the three months ended March 31, 2004 and 2003, respectively.

SIRIUS SATELLITE RADIO INC. AND SUBSIDIARY
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — CONTINUED
(Dollar amounts in thousands, unless otherwise stated)
(Unaudited)

The non-cash stock compensation expense for the three months ended March 31, 2004 includes $2,647 as a result of the accelerated vesting of options during the quarter upon the satisfaction of 2003 performance criteria.

(Unaudited)

Penske companies warrants to purchase an aggregate of 38,000,000 shares of our common stock at an exercise price of $2.392 per share.

In January 2000, we issued DaimlerChrysler a warrant to purchase 4,000,000 shares of our common stock at an exercise price of $60.00 per share. In October 2002, we cancelled the warrant previously issued to DaimlerChrysler and issued a new warrant, which entitles DaimlerChrysler to purchase up to 4,000,000 shares of our common stock at a purchase price of $3.00 per share. This warrant is exercisable based upon the number of new vehicles equipped to receive our broadcasts DaimlerChrysler manufactures, and is fully exercisable after 3,200,000 new DaimlerChrysler vehicles equipped to receive our broadcasts are manufactured. There was no accounting impact associated with the cancellation of the original warrant and subsequent issuance of the new warrant as DaimlerChrysler had not begun to perform under the agreement. We record warrant expense based upon the satisfaction of performance criteria and the fair value of the warrants at each reporting date. The final measurement date of these warrants will be the date that each performance commitment for such warrants is satisfied.

The new warrant is exercisable based upon certain corporate events and the number of new vehicles equipped to receive our broadcasts Ford manufactures, and is fully exercisable after 1,500,000 new Ford vehicles equipped to receive our broadcasts are manufactured. There was no accounting impact associated with the cancellation of the original warrant and subsequent issuance of the new warrant as Ford had not begun to perform under the agreement.

In connection with the Lehman term loan facility, we granted Lehman Commercial Paper Inc. 2,100,000 warrants, each to purchase one share of our common stock, at an exercise price of $29.00 per share.

SIRIUS SATELLITE RADIO INC. AND SUBSIDIARY
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — CONTINUED
(Dollar amounts in thousands, unless otherwise stated)
(Unaudited)

We granted an investor warrants to purchase 1,800,000 shares of our common stock at $50.00 per share during the period from June 15, 1998 until June 15, 2005, subject to certain conditions. We may redeem all of these warrants if the price of our common stock is at least $75.00 per share during a specified period. As of March 31, 2004, all of these warrants were outstanding.

We recognized expense of $9,271 and $1 in connection with these warrants for the three months ended March 31, 2004 and 2003, respectively.

10. Employee Benefit Plans

Stock Option Plans

In February 1994, we adopted our 1994 Stock Option Plan (the “1994 Plan”) and our 1994 Directors’ Nonqualified Stock Option Plan (the “Directors’ Plan”). In June 1999, we adopted the Sirius Satellite Radio 1999 Long-Term Stock Incentive Plan (the “1999 Plan”). In March 2003, we adopted the Sirius Satellite Radio 2003 Long-Term Stock Incentive Plan (the “2003 Plan”). As of March 31, 2004, approximately 499,611,049 shares of our common stock were available for grant under these plans. Employees and consultants 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 generally vest over three to five years from the date of grant and expire in ten years.

In 2003, we granted a total of 47,707,250 nonqualified stock options to employees and consultants with an exercise price of $1.04 per share. Since the exercise price of these stock options was less than the fair market value of the underlying common stock on the date of grant, we recorded deferred compensation, a component of stockholders’ equity, of $30,299 in 2003. This deferred compensation is amortized to non-cash stock compensation expense over the vesting period. Approximately 42% of these options vest ratably over three years and 33% vest in July 2008 with acceleration to March 2005 if performance criteria are satisfied in 2004. 25% of these options vested in March 2004 upon the satisfaction of performance criteria. Employees exercised 1,786,001 of these options in the first quarter of 2004 resulting in proceeds to us of $1,857. During the three months ended March 31, 2004, we recognized non-cash stock compensation associated with these stock options of $4,376, including $2,647 of non-cash stock compensation expense related to the accelerated vesting of stock options during the quarter upon the satisfaction of performance criteria in 2003.

Restricted Stock Units

In 2003, we granted 16,860,000 restricted stock units, with a weighted average grant date fair value of $1.65 per share, to certain employees. Each restricted stock unit entitles the holder to receive one share of common stock upon vesting in July 2008 with acceleration to March 2006 if performance criteria are satisfied with respect to the year ending December 31, 2005. We recorded deferred compensation of $27,811 in 2003 in connection with these restricted stock units, which will be amortized to non-cash stock compensation expense over the vesting period. For the three months ended March 31, 2004, we recognized non-cash stock compensation expense associated with these restricted stock units of $1,847.

11. Income Taxes

We recorded income tax expense of $2,521 for the three months ended March 31, 2004. 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.

Operating Leases

We have entered into operating leases related to our national broadcast studio, office space, terrestrial repeater sites and equipment.

Satellite and Transmission

We have entered into an agreement with a provider of satellite services to operate our off-site satellite telemetry, tracking and control facilities.

Programming and Content

We have entered into agreements with licensors of music and non-music programming and, in certain instances, are obligated to pay license fees, guarantee minimum advertising revenue share or purchase advertising on properties owned or controlled by these licensors. In addition, we have agreements with various rights organizations pursuant to which we pay royalties for public performances of music. In January 2004, we signed a seven-year agreement with the National Football League to broadcast NFL games live nationwide, and to become the Official Satellite Radio Partner of the National Football League, with exclusive rights to use the NFL “shield” logo and collective NFL team trademarks. We have agreed to pay the NFL an aggregate of $188,000 in cash during the term of the agreement. $10,000 of this amount was paid in connection with the announcement and execution of our agreement with the NFL and $85,000 was deposited in escrow to pay rights fees for the 2006-2009 NFL seasons. The $85,000 deposited in escrow is included in restricted investments on our consolidated balance sheets and is not included as a contractual commitment in the table above.

Customer Service and Billing

We have entered into agreements with third parties to provide customer service, billing and subscriber management services.

Marketing and Distribution

We have entered into various marketing, sponsorship and distribution agreements to promote our brand and as a result are obligated to make payments to sponsors, retailers, automakers and radio manufacturers. We have also agreed to reimburse automakers for certain engineering and development costs associated with the incorporation of SIRIUS radios into vehicles they manufacture.

Chip Set Development and Production

We have entered into an agreement with Agere Systems, Inc. (“Agere”) to develop and produce chip sets for use in SIRIUS radios. This agreement requires Agere to produce a minimum quantity of chip sets during each year of the agreement. In April 2004, we executed an agreement with STMicroelectronics, one of the largest suppliers of integrated circuits in the world, to produce and integrate our next generation chip set. This agreement requires us to purchase a minimum of 1,500,000 chip sets during a three-year period for an aggregate price of approximately $20,000, and pay for the development of the chips as milestones are satisfied. Such contractual commitments are not included in the table of cash contractual obligations as of March 31, 2004 but will impact our cash obligation in future periods.

(Unaudited)

Joint Development Agreement

Under the terms of a joint development agreement with XM Satellite 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. For the three months ended March 31, 2004, we incurred costs of $288 under this agreement. We did not incur any costs associated with the joint development agreement for the three months ended March 31, 2003. The costs related to the joint development agreement are being expensed as incurred in research and development. We are currently unable to determine the expenditures necessary to complete this process, but they may be significant.

Other Commitments

We have agreed to use reasonable efforts to assist certain manufacturers of SIRIUS radios and components for those radios in the event that production of such radios and components are greater than sales. In certain circumstances, these reasonable efforts may include the purchase of unsold SIRIUS radios or components. In addition, we have also entered into agreements with automakers, radio manufacturers and others that include per-radio and per-subscriber required payments and revenue sharing arrangements. These future costs are dependent upon many factors and are difficult to anticipate; however, these costs may be substantial. We may enter into additional programming, marketing and other agreements that contain provisions similar to our current agreements.

Through March 31, 2004, we have not entered into any off-balance sheet arrangements or transactions.

Risks and Uncertainties

Agere is currently the sole supplier of chip sets to our radio manufacturers. Although there are a limited number of manufacturers of these chip sets, we believe that other suppliers could provide similar chip sets on comparable terms. A change of suppliers could cause a delay in manufacturing and a possible loss of sales, which would adversely affect our operating results.

A significant number of SIRIUS radios are produced by a single vendor due to technology, availability, price, quality and other considerations. In the event that the supply of these SIRIUS radios were delayed or reduced, the ability of manufacturers to ship SIRIUS radios in the desired quantities and in a timely manner would adversely affect our operating results.

13. Subsequent Event

In April 2004, we purchased, and now operate, the facility that our satellite uplink is located on for $2,500 in cash. This purchase included the land, buildings and associated equipment at the site.

In April 2004, we amended our agreement with DaimlerChrysler. As part of this amended agreement, DaimlerChrysler will bundle a one-year subscription to our service in all of its vehicles that contain a factory-installed SIRIUS radio. DaimlerChrysler has agreed to use commercially reasonable efforts to produce and distribute an aggregate of 550,000 such bundled vehicles by June 30, 2006. We will receive from DaimlerChrysler our standard one-year subscription fee for each bundled subscription. We have agreed to reimburse DaimlerChrysler for the costs of factory-installed SIRIUS radios and to pay incentives to DaimlerChrysler upon the achievement of agreed upon volume thresholds. DaimlerChrysler will continue to offer SIRIUS radios as a dealer-installed option in the majority of its remaining vehicles. We intend to issue DaimlerChrysler AG warrants to purchase an aggregate of up to 21,500,000 shares of our common stock at an exercise price of $1.04 per share. These warrants will vest based on the achievement of various performance milestones, including the volume thresholds contained in our agreement with DaimlerChrysler Corporation. When issued, these warrants will replace the warrants issued to DaimlerChrysler AG in October 2002.

In April 2004, we executed an agreement with STMicroelectronics, one of the largest suppliers of integrated circuits in the world, to produce and integrate our next generation chip set. This agreement requires us to purchase a minimum of 1,500,000 chip sets during a three-year period for an aggregate price of approximately $20,000, and pay for the development of the chips as milestones are satisfied.

(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,” “intends,” “plans,” “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, 2003 (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 Part I 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 competitive position; XM Satellite Radio, the other satellite radio service provider in the United States, currently has substantially more subscribers than us and may have certain competitive advantages;

•

our dependence upon third parties to manufacture, distribute, market and sell SIRIUS radios and components for those radios;

•

the unproven market for our service;

•

changes to our business plan or strategy, which could include significant additions to our programming, infrastructure or distribution; and

•

the useful life of our satellites, which have experienced circuit failures on their solar arrays and other component failures; certain satellite failures may not be covered by insurance and we regularly evaluate whether to continue to insure our satellites.

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

We are one of two satellite radio service providers in the United States. We broadcast over 110 channels of digital-quality entertainment: over 60 channels of 100% commercial-free music and over 50 channels of sports, news, entertainment, traffic, weather and children’s programming for an effective monthly subscription fee of $11.15 for a three year plan and up to $12.95 for a monthly plan. We offer discounts for pre-paid and long-term subscriptions as well as discounts for multiple subscriptions. Approximately 68% of our new subscribers acquired during the three months ended March 31, 2004 purchased an annual subscription with an effective monthly subscription fee of $11.87.

Since inception, we have used substantial resources to develop our satellite radio system. Our satellite radio system consists of our FCC license, satellite system, national broadcast studio, terrestrial repeater network and satellite telemetry, tracking and control facilities. Our satellites were successfully launched on June 30, 2000, September 5, 2000 and November 30, 2000. On July 1, 2002, we launched our service nationwide.

Our primary source of revenue is subscription fees, with most of our new customers subscribing to SIRIUS on an annual basis. We also derive revenue from activation fees, the sale of advertising on our non-music channels and the direct sale of SIRIUS radios.

Our costs of services include satellite and transmission, programming and content, customer service and billing, and costs associated with the sale of equipment. Satellite and transmission expenses consist primarily of in-orbit satellite insurance and costs associated with the operation and maintenance of our satellite tracking, telemetry and control system, terrestrial repeater network and national broadcast studio. Programming and content expenses include costs to acquire programming from third parties, on-air talent costs and broadcast royalties. Customer service and billing costs include costs associated with the operation of our customer service center and subscriber management system.

As of March 31, 2004, we had 351,663 subscribers as compared to 261,061 as of December 31, 2003. Subscriptions, including those currently in promotional periods and those which have prepaid, and active SIRIUS radios under our agreement with Hertz, are included in our subscriber totals.

The following chart contains a breakdown of our subscribers as of the dates set forth below:

	March 31, 2004	December 31, 2003	September 30, 2003	June 30, 2003	March 31, 2003
Retail	263,164	197,650	110,821	77,713	51,969
OEM and Special Markets	63,493	39,400	15,358	7,630	4,252
Hertz	25,006	24,011	23,433	19,843	11,838
Total subscribers	351,663	261,061	149,612	105,186	68,059

SIRIUS radios are primarily distributed through automakers and retailers. We have agreements with Ford Motor Company, DaimlerChrysler Corporation, BMW of North America, LLC, Nissan North America, Inc. and Volkswagen of America, Inc. that contemplate the manufacture and sale of vehicles that include SIRIUS radios. In the autosound aftermarket, SIRIUS radios are available for sale at national and regional retailers, including Best Buy, Circuit City, Ultimate Electronics, Tweeter Home Entertainment Group, Crutchfield and Good Guys. In February 2004, we announced an agreement with RadioShack Corporation, one of the nation’s largest consumer electronics retailers with more than 7,000 outlets nationwide, to distribute, market and sell SIRIUS radios. On March 31, 2004, SIRIUS radios were available at approximately 6,500 retail locations. SIRIUS radios are also offered to renters of Hertz vehicles at approximately 53 airport locations. We believe our ability to attract and retain subscribers depends in large part on creating and sustaining distribution channels for SIRIUS radios, both in the retail aftermarket and with automakers, and on the quality and entertainment value of our programming.

During 2003 we improved our financial position significantly through the issuance of debt and equity securities. We issued 371,151,111 shares of our common stock for net proceeds of $494,497 and $201,250 in aggregate principal amount of our 3½% Convertible Notes due 2008 for net proceeds of $194,224. We also restructured our debt and equity capitalization, which resulted in the elimination of 91% of our then outstanding debt. The increase in our overall liquidity, reduction of the average interest rate on our outstanding debt and reduction of our overall leverage has better positioned us to meet our business plan.

In the first quarter of 2004, we continued to improve our financial position with the issuance of $300,000 in aggregate principal amount of our 2½% Convertible Notes due 2009 resulting in net proceeds of $293,600. We also focused on our brand awareness, acquired programming and expanded the distribution of SIRIUS radios. Specifically,

•

we signed an agreement with Penske Automotive Group, Inc., United Auto Group, Inc., Penske Truck Leasing Co. L.P. and Penske Corporation. The Penske companies have agreed, where available, to order SIRIUS radios with the vehicles they purchase from automakers, and to use their best efforts to include a bundled subscription to our service in the sale or lease of these vehicles;

•

we signed a seven-year agreement with the National Football League to broadcast NFL games live nationwide, and to become the Official Satellite Radio Partner of the National Football League, with exclusive rights to use the NFL “shield” logo and collective NFL team trademarks;

•

we announced an agreement with RadioShack to distribute, market and sell SIRIUS radios. Our agreement with RadioShack is expected to significantly increase our retail distribution in the second half of 2004; and

•

we executed an agreement with affiliates of EchoStar Communications Corporation. EchoStar has agreed to purchase, distribute, market and sell SIRIUS radios through its extensive network of satellite television dealers and through certain other retailers and distributors.

We have incurred operating losses since inception and expect to continue to incur operating losses until the number of our subscribers increases substantially and we develop cash flows sufficient to cover our operating costs. We also have significant contracts and commercial commitments over the next several years, including subsidies and distribution costs, programming costs, repayment of long-term debt and lease payments as further described below under the heading “Contractual Commitments.” Our ability to become profitable also depends upon other factors identified below under the heading “Liquidity and Capital Resources.”

Results of Operations

Three Months Ended March 31, 2004 Compared with Three Months Ended March 31, 2003

Total Revenue. Total revenue increased $7,700 to $9,291 for the three months ended March 31, 2004 from $1,591 for the three months ended March 31, 2003. Total revenue for the three months ended March 31, 2004 included subscriber revenue of $9,202, consisting of subscription and non-refundable activation fees, net advertising revenue of $20, equipment revenue of $50 and revenue from other sources of $19. Total revenue for the three months ended March 31, 2003 included subscriber revenue of $1,554, net advertising revenue of $17 and revenue from other sources of $20.

Subscriber Revenue. The increase in subscriber revenue of $7,648 was attributable to the growth of subscribers to our service. We added 283,604 net new subscribers since March 31, 2003 and had 351,663 subscribers as of March 31, 2004. We added 38,112 net new subscribers during the three months ended March 31, 2003 and had 68,059 subscribers as of March 31, 2003. Subscriber revenue for the three months ended March 31, 2004 included subscription revenue of $9,859 and activation revenue of $404, which was offset by $1,061 of costs associated with mail-in rebate programs. Subscriber revenue for the three months ended March 31, 2003 included subscription revenue of $1,523 and activation revenue of $43, which was offset by $12 of costs associated with mail-in rebate programs. Activation fees are recognized ratably over the term of the subscriber relationship, currently estimated to be 3.5 years. An estimate of mail-in rebates that are paid by us directly to subscribers are recorded as a reduction to subscription revenue in the period the subscriber activates our service. In subsequent periods estimates are adjusted when necessary. Future subscription revenue will be dependent upon, among other things, the growth of our subscriber base, discounts and mail-in rebates offered to subscribers and the identification of additional revenue streams from subscribers.

Average monthly revenue per subscriber, or ARPU. ARPU, which is not a measure of financial performance under accounting principles generally accepted in the United States, is derived from total subscriber revenue over the daily weighted average number of subscribers for the period and is used by us as a measure of operational performance. ARPU for the three months ended March 31, 2004 was $9.92. This amount included the dilutive effects of mail-in rebate programs of $1.14 and the dilutive effects of Hertz subscribers of $0.62. The Hertz program generated $5.17 of revenue per subscriber per month during the three months ended March 31, 2004, resulting in dilution to ARPU. ARPU for the three months ended March 31, 2003 was $10.90. This amount included the dilutive effects of mail-in rebate programs of $0.08 and the dilutive effects of Hertz subscribers of $0.98. The Hertz program generated $5.30 of revenue per subscriber per month during the three months ended March 31, 2003, resulting in dilution to ARPU. Future ARPU will be dependent upon the amount and timing of subscriber discounts, mail-in rebate programs, and the identification of additional revenue streams from subscribers.

Set forth below is a chart showing the calculation of ARPU and the average monthly revenue per Hertz subscriber for the three months ended March 31, 2004 and 2003:

	For the Three Months Ended March 31,
	2004			2003
Average monthly revenue per subscriber	$	11.68		$	11.96
Effects of Hertz subscribers		(0.62	)		(0.98	)
ARPU before effects of mail-in rebates	$	11.06			10.98
Effects of mail-in rebate programs		(1.14	)		(0.08	)
Reported ARPU	$	9.92		$	10.90
Average monthly revenue per Hertz subscriber	$	5.17		$	5.30

Lower ARPU for the three months ended March 31, 2004 as compared to the three months ended March 31, 2003 is a direct result of the mail-in rebate programs, the introduction of our three months free promotion and the continued success of our $6.99 preferred plan and lifetime plan. ARPU will fluctuate based on promotions implemented in future periods.

Satellite and Transmission. Satellite and transmission expenses increased $1,155 to $9,022 for the three months ended March 31, 2004 from $7,867 for the three months ended March 31, 2003. Satellite and transmission expenses consist of in-orbit satellite insurance and costs associated with the operation and maintenance of our satellite tracking, telemetry and control system, terrestrial repeater network and national broadcast studio. The increase in satellite and transmission expenses is primarily attributable to an increase of $255 in satellite and broadcast engineering costs and an increase of $338 for additions to our terrestrial repeater network. As of March 31, 2004, we had 133 repeaters in operation as compared to 97 as of March 31, 2003. In addition, for the three months ended March 31, 2004 we incurred approximately $165 for royalties associated with the use of security software to prevent the theft of our service. We did not incur any costs related to this software for the three months ended March 31, 2003. The remaining increase was primarily attributable to personnel related costs.

We expect a significant portion of our satellite and transmission expenses to remain relatively constant. Any increases or decreases in these expenses will be due primarily to costs of insuring our in-orbit satellites and additions to our terrestrial repeater network. We regularly evaluate the benefits of maintaining our satellite insurance, and may discontinue our satellite insurance if we consider it reasonably prudent to do so.

Programming and Content. Programming and content expenses increased $2,604 to $9,178 for the three months ended March 31, 2004 from $6,574 for the three months ended March 31, 2003. Programming and content expenses include costs to create, produce and acquire content, on-air talent costs and broadcast royalties. We have entered into various agreements with third parties for music and non-music programming. These agreements require us to share advertising revenue, pay license fees, purchase advertising on media properties owned or controlled by the licensor and pay certain other guaranteed obligations. Advertising revenue share is expensed as the associated revenue is recognized; license fees are expensed as the programming is aired; purchased advertising is recorded as a sales and marketing expense when the advertising is aired; and guaranteed obligations are recognized on a straight-line basis over the term of the applicable agreement. The costs of sports programming agreements which are for a specified number of events are amortized on an event-by-event basis; and those which are for specified seasons are amortized over the seasons on a straight-line basis.

In January 2004, we signed an agreement with the NFL whereby we agreed to pay an aggregate of $188,000 in license fees. In addition to the license fees, we issued to the NFL 15,173,070 shares of our common stock valued at $40,967 and warrants, which we refer to as media-based warrants, to purchase 16,666,665 shares of our common stock at a price of $2.50 per share, which vest upon delivery to us of media assets by the NFL and its member clubs. For the three months ended March 31, 2004, we recognized $488 in expense for the common stock granted to the NFL. We recognized no expense for the license fees or media-based warrants.

In addition to the $488 in expense associated with the NFL, the increase in programming and content expenses was primarily attributable to an increase of $1,811 for costs to create, produce and acquire content, including consultant costs incurred to assist us with the acquisition of content, and an increase of $161 for additional on-air talent. We have also entered into agreements with various rights organizations pursuant to which we pay royalties for public performances of music. These agreements include fixed and variable payment obligations. We record variable broadcast royalties as they are incurred and fixed obligations on a straight-line basis over the term of the applicable agreement. Variable broadcast royalties increased $144 as a result of an increase in our subscriber base.

Our agreement with the NFL will result in additional programming and content expenses over the next seven years. A portion of the expense associated with the media-based warrants we granted the NFL will be allocated to programming and content expense as NFL member clubs deliver to us content for use on the NFL Satellite Radio Network. Expense associated with these warrants is based on the fair market value of our common stock. Fair market value could fluctuate at each reporting date until the final measurement date when the performance criteria are met; therefore, our expense is not readily predictable.

We anticipate that our programming and content costs will increase significantly as we continue to develop and enhance our channels. We regularly evaluate new programming opportunities and may choose to acquire new content in the future at substantial costs.

Customer Service and Billing. Customer service and billing costs increased $1,658 to $3,860 for the three months ended March 31, 2004 from $2,202 for the three months ended March 31, 2003. Customer service and billing costs include expenses associated with the operation of our customer service center and subscriber management system. The increase in customer service and billing costs is primarily attributable to an additional $1,256 in customer service representative and telecommunication costs as a result of an increase in the number of representatives at our customer service center needed to support the growth of our subscriber base; an increase of $504 in credit card fees, also as a result of the growth of our subscriber base and the success of our lifetime plan; and an increase of $200 for consultants hired to support our customer service and billing infrastructure. These increases were offset by a decrease in operation and maintenance fees related to our current subscriber management system, which replaced our prior system in May 2003. Customer service and billing costs increased 75.3% compared to an increase in our end of period subscribers of 416.7% for the three months ended March 31, 2004 as compared to the three months ended March 31, 2003.

We continue to evaluate the effectiveness of our billing system, and implement enhancements to the system. We expect our total customer care and billing costs to increase and our costs per gross activation to decrease as our subscriber base grows.

Sales and Marketing. Sales and marketing expenses increased $3,467 to $34,953 for the three months ended March 31, 2004 from $31,486 for the three months ended March 31, 2003. Sales and marketing expenses include advertising media and production activities, payments to reimburse retailers, distributors, radio manufacturers and automakers for marketing and promotional activities, and expense for certain equity securities granted to third parties. Excluding expense for certain equity securities granted to third parties, sales and marketing expenses decreased $5,803 to $25,682 for the three months ended March 31, 2004 from $31,485 for the three months ended March 31, 2003.

Advertising Media and Production. Advertising media and production expense includes promotional events, sponsorships, media, advertising production and market research. Such costs are expensed as incurred. Advertising media and production costs decreased for the three months ended March 31, 2004 as compared to the three months ended March 31, 2003 primarily as a result of the expiration of our Nascar sponsorship and a decrease in media spending for both print and television advertising.

Distribution. Distribution costs associated with our automakers and retailers include the costs of advertising, residual payments, market development funds, revenue share payments and in-store merchandising. Advertising is expensed as incurred. Residuals are monthly fees paid based upon the number of subscribers using a SIRIUS radio purchased from a retailer and are expensed as incurred. Market development funds are fixed and variable payments to reimburse retailers, automakers and radio manufacturers for the cost of advertising and other product awareness activities. Fixed market development funds are expensed over the periods specified in the applicable agreement; variable costs are expensed at the time a subscriber is activated. Revenue share is expensed as the corresponding subscription revenue is earned. Distribution costs decreased for the three months ended March 31, 2004 as compared to March 31, 2003 primarily as a result of a decrease in co-op advertising and market development funds pursuant to contractual obligations offset by an increase in residuals and revenue share as a result of the growth in our subscribers.

Equity Securities Granted to Third Parties. We have issued a warrant to purchase 4,000,000 shares of our common stock to each of DaimlerChrysler and Ford. These warrants become exercisable based on, among other conditions, the number of enabled vehicles the automakers manufacture. Pursuant to an amended agreement we entered into with

DaimlerChrysler in April 2004, we intend to issue DaimlerChrysler warrants to purchase an aggregate of up to 21,500,000 shares of our common stock. When issued these warrants will replace the 4,000,000 warrants originally granted to DaimlerChrysler. We record warrant expense based upon the performance of the automakers in manufacturing enabled vehicles and the fair value of the warrants at each reporting date. The final measurement date of these warrants will be the date that each performance commitment for such warrants is satisfied. In January 2004, we signed an agreement with Penske Automotive Group, Inc., United Auto Group, Inc., Penske Truck Leasing Co. L.P. and Penske Corporation. In connection with this agreement, we agreed to issue the Penske companies warrants to purchase an aggregate of 38,000,000 shares of our common stock at an exercise price of $2.392 per share. Two million of these warrants vest upon issuance and the balance of these warrants vest over time and upon achievement of certain milestones by the Penske companies. For the three months ended March 31, 2004, we recorded $9,271 in expense associated with warrants granted to third parties as compared to $1 for the three months ended March 31, 2003. In January 2004, we signed an agreement with the NFL whereby we agreed to pay an aggregate of $188,000 in license fees. In addition to the license fees, we issued to the NFL warrants, which we refer to as media-based warrants, to purchase 16,666,665 shares of our common stock at a price of $2.50 per share, which vest upon delivery to us of media assets by the NFL and its member clubs. We recognized no expense for the license fees or media-based warrants for the three months ended March 31, 2004.

We expect sales and marketing expenses to increase in the future as we continue to build brand awareness through national advertising and promotional activities and expand the distribution of SIRIUS radios. Such increase will include the impact of the agreements we entered into in the first quarter of 2004 with Penske, RadioShack, EchoStar and the NFL. Pursuant to these agreements, we expect to incur additional expense in connection with joint marketing efforts and the issuance of warrants to purchase our common stock. Expense associated with joint marketing efforts will be expensed as incurred, while expense associated with the issuance of warrants will be recognized based on the fair value of the warrants as targets or milestones are achieved. A portion of the fair value of the media-based warrants issued in connection with our NFL agreement will be expensed over the NFL season to sales and marketing expense with respect to that portion of the warrants attributable to marketing activities only. Expense associated with warrants is based on the fair market value of our common stock. Fair market value could fluctuate at each reporting date until the final measurement date when the performance criteria are met; therefore, our expense is not readily predictable.

Subscriber Acquisition Costs. Subscriber acquisition costs increased $15,117 to $26,981 for the three months ended March 31, 2004 from $11,864 for the three months ended March 31, 2003. Subscriber acquisition costs include incentives to purchase, install and activate SIRIUS radios as well as subsidies paid to radio manufacturers, automakers, retailers and payments to Agere Systems, Inc. (“Agere”) for chip sets. Certain 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 sharing payments to manufacturers of SIRIUS radios. We retain ownership of the SIRIUS radios used in our agreement with Hertz; as a result, amounts capitalized in connection with this program are not included in our subscriber acquisition costs.

The increase in subscriber acquisition costs is primarily attributable to higher shipments of SIRIUS radios to support our future growth; an increase in commissions as a result of higher activations in the three months ended March 31, 2004 as compared to the three months ended March 31, 2003; and an increase in chip set subsidies as a result of purchase commitments under our agreement with Agere. In addition to chip set subsidies included in subscriber acquisition costs, as of March 31, 2004, approximately $8,360 of chip sets delivered to us by Agere will be shipped to radio manufacturers in future periods, and are included in other current assets on our consolidated balance sheets.

Subscriber acquisition costs per gross activation, which is not a measure of financial performance under accounting principles generally accepted in the United States, is derived from total subscriber acquisition costs and the negative margins from the sale of SIRIUS radios over the number of gross activations for the period and is used by us as a key operating performance indicator. Total subscriber acquisition costs per gross activation for the three months ended March 31, 2004 was $248. Of this amount, approximately $70 per gross activation represented the costs of promotional activities. Subscriber acquisition costs per gross activation, net of promotional activities, was approximately $178 per gross activation for the three months ended March 31, 2004.

We expect total subscriber acquisition costs to increase in the future as our gross activations increase and we continue to offer subsidies, commissions and other incentives to acquire subscribers. Subscriber acquisition costs in future periods are also expected to include expense for the fair value of 33,333,335 bounty-based warrants we granted to the NFL. These warrants will be earned by the NFL as we acquire subscribers which are directly trackable through efforts of the NFL. Expense associated with these warrants will be based on the fair market value of our common stock. Fair market value could fluctuate at each reporting date until the final measurement date when the subscriber targets are met; therefore, our expense is not readily predictable. We do anticipate that the costs of certain subsidized components of SIRIUS radios will decrease in the future as manufacturers experience economies of scale in production and we secure additional manufacturers of these components.

General and Administrative. General and administrative expenses decreased $1,225 to $7,869 for the three months ended March 31, 2004 from $9,094 for the three months ended March 31, 2003. General and administrative expenses include rent and occupancy, accounting, legal, human resources, information technology and investor relations costs. The decrease was primarily a result of a reduction in legal fees of $1,648 related to the termination of our agreement with the prior provider of our subscriber management system in 2003. This decrease was offset by an overall increase in bad debt expense due to the growth of our subscriber base.

Research and Development. Research and development expense decreased $1,854 to $5,119 for the three months ended March 31, 2004 from $6,973 for the three months ended March 31, 2003. Research and development costs include the costs to develop our next generation of chip sets and new products and costs associated with the incorporation of SIRIUS radios into vehicles manufactured by automakers. Our agreement with Agere to develop and produce chip sets for use in SIRIUS radios requires Agere to manufacture a minimum quantity of chip sets during each year of the agreement, and requires us to pay Agere fixed monthly payments. These costs are allocated between research and development and subscriber acquisition costs for development work and chip set production. The decrease in research and development expense is primarily attributable to a decrease in non-recurring engineering costs related to the development of our chip sets. Such decrease in expense was offset by increases related to our joint development agreement with XM Satellite Radio for which we incurred no related expense for the three months ended March 31, 2003 and salary and consulting expense related to the addition of headcount to support the continued development of future generation chip sets and products.

We expect our research and development expense to increase in future periods as automakers continue their efforts to incorporate SIRIUS radios across a broad range of their vehicles and as we develop future generations of chip sets and new products. Our April 2004 agreement with STMicroelectronics to produce and integrate our next generation chip set will require us to pay ST agreed upon amounts for the development of chip sets as milestones are satisfied. Such costs will be recorded to research and development expense.

Non-Cash Stock Compensation. We recognized non-cash stock compensation expense of $8,065 and $559 for the three months ended March 31, 2004 and 2003, respectively. Non-cash stock compensation includes charges and benefits associated with the grant of certain stock options and restricted stock units and the issuance of our common stock to employees and employee benefit plans. The increase is primarily a result of expense recognized during the quarter related to the issuance of approximately 65,000,000 stock-based awards issued to employees and consultants in 2003, which include a combination of stock options with an exercise price of $1.04 per share and restricted stock units. The difference between the exercise price and the market price on the date of grant is recorded to non-cash stock compensation expense over the applicable vesting period. Included in the expense associated with these stock-based awards for the three months ended March 31, 2004 is $2,647 associated with the accelerated vesting of options during the quarter upon the satisfaction of performance criteria in 2003. Future non-cash stock compensation is contingent upon a number of factors, including the price of our common stock and the vesting date of stock options and restricted stock units, and could materially change.

Debt Restructuring. We recorded a gain of $256,538 in connection with the restructuring of our long-term debt for the three months ended March 31, 2003. This gain represents the difference between the carrying value of our 15% Senior Secured Discount Notes due 2007, 14½% Senior Secured Notes due 2009, Lehman term loans and Loral term loans, including accrued interest, and the fair market value of the common stock issued, adjusted for unamortized debt issuance costs and direct costs associated with the restructuring. This gain is net of a loss on our 8¾% Convertible Subordinated Notes due 2009 exchanged in the restructuring. The loss represents the difference between the fair market value of the common stock issued in the exchange and the fair market value of the common stock which would have been issued under the original conversion ratio, including accrued interest, adjusted for unamortized debt issuance costs and direct costs associated with the restructuring.

Interest Expense. Interest expense increased $5,034 to $23,699 for the three months ended March 31, 2004 from $18,665 for the three months ended March 31, 2003. The increase in interest expense was attributable to debt conversion costs incurred as a result of the exchange of debt for our common stock, offset by a decrease of interest expense as a result of a reduction in our outstanding debt obligations. Debt conversion costs represent the loss on conversion associated with the debt exchanged. Such costs were $19,592 for the three months ended March 31, 2004.

Income Tax Expense. We recorded income tax expense of $2,521 for the three months ended March 31, 2004. 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.

Liquidity and Capital Resources

We have financed our operations through the sale of debt and equity securities. As of March 31, 2004, we had cash, cash equivalents and marketable securities totaling $706,664 and working capital of $652,749, compared with cash, cash equivalents and marketable securities totaling $289,742 and working capital of $263,268 as of March 31, 2003. Since December 31, 2002, our recapitalization and the issuance of convertible debt and common stock in exchange for net proceeds of $982,321 substantially improved our liquidity.

In January 2004, we signed a seven-year programming and marketing agreement with the NFL. In connection with this agreement, we paid $5,000 in December 2003, $5,000 in February 2004 and $85,000 was deposited in escrow. We are not required to make further payments to the NFL until August 2009. In the first quarter of 2004, we also issued $300,000 in aggregate principal amount of our 2½% Convertible Notes due 2009, resulting in net proceeds of $293,600. We intend to use these proceeds for general corporate purposes, including investments in programming and infrastructure and to pay the costs of retail and automotive distribution arrangements. In January 2004, we also issued 21,027,512 shares of our common stock for $19,850 in net proceeds in connection with Blackstone’s exercise of certain warrants.

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. Our financial projections are based on assumptions which we believe are reasonable but contain significant uncertainties. As of March 31, 2004, we had 351,663 subscribers. We currently expect that we will need approximately two million subscribers before we achieve cash flow breakeven, which we estimate will occur by the end of 2005. We may change our plans and, as a result, our actual funding requirements could vary materially. We may need to raise additional funds through the sale of additional debt and equity securities to fund costs that are not contemplated by our business plan. Such costs may include the costs of acquiring new programming as well as distribution costs and subscriber acquisition costs, investing in our infrastructure and/or potential acquisitions. The sale or issuance of additional equity or convertible debt securities could result in dilution to our stockholders. The incurrence of indebtedness would result in increased fiscal obligations and could result in operating covenants that would restrict our operations. We cannot provide assurance that these additional sources of funds will be available, or, if available, would have reasonable terms.

Cash Flows for the Three Months Ended March 31, 2004 Compared with Three Months Ended March 31, 2003

Net cash used in operating activities remained relatively consistent at $71,871 for the three months ended March 31, 2004 as compared to $71,140 for the three months ended March 31, 2003. Net cash used in operating activities adjusted for non-cash items and before changes in assets and liabilities was $82,506 for the three months ended March 31, 2004 as compared to $90,023 for the three months ended March 31, 2003, a decrease of $7,517. This decrease in the net outflow of cash was primarily attributable to the increase in revenue of $7,700 as expenses, excluding the effects of non-cash items, remained relatively consistent. Cash outflows for the three months ended March 31, 2004 and 2003 were used to fund our cost of services and other operating expenses primarily to obtain additional content on our music and non-music channels and to market our service to potential subscribers. In addition, we continued to pay incentives and subsidies to acquire new subscribers. We expect to continue to have net outflows of cash for the remainder of 2004 to fund our operations. For the three months ended March 31, 2004, we had an inflow of cash from subscribers on annual subscription plans and certain other prepaid subscription programs for which we record deferred revenue. We expect such deferred revenue balance to increase in future periods as our subscriber base grows. This inflow of cash was partially offset by the outflow of cash for chip sets delivered to us by Agere which will be shipped to radio manufacturers in future periods. Such amounts are included in the prepaid and other current assets change in the consolidated statements of cash flows for the three months ended March 31, 2004.

Net cash used in investing activities was $62,922 for the three months ended March 31, 2004 compared to net cash provided by investing activities of $114,595 for the three months ended March 31, 2003. For the three months ended March 31, 2004, we deposited $85,000 in escrow in connection with the NFL agreement. We received $25,000 and $120,000 for the three months ended March 31, 2004 and 2003, respectively, as a result of the maturity of certain available-for-sale securities.

Net cash provided by financing activities was $314,870 and $192,350 for the three months ended March 31, 2004 and 2003, respectively. During the three months ended March 31, 2004 we issued $300,000 in principal amount of our 2½% Convertible Notes due 2009 resulting in net proceeds of $293,600. We also received proceeds from the exercise of options and warrants of $1,453 and $19,850, respectively. During the three months ended March 31, 2003, we sold shares of common stock resulting in net proceeds of $197,112 and incurred costs associated with our debt restructuring of $4,737.

2003 Long-Term Incentive Plan

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. The purpose of the 2003 Plan is to promote our long-term financial success by enhancing our ability to attract, retain and reward individuals who contribute to our success and to further align our personnel with stockholders. Employees and consultants are eligible to receive awards under the 2003 Plan. As of March 31, 2004, approximately 499,611,049 shares of our common stock were available for grant under the 2003 Plan.

In 2003, we granted a total of 47,707,250 stock options to employees and consultants with an exercise price of $1.04 per share. Approximately 42% of these options vest ratably over three years and 33% vest in July 2008 with acceleration to March 2005 if performance criteria are satisfied in 2004. 25% of these options vested in March 2004 upon the satisfaction of performance criteria. Employees exercised 1,786,001 of these stock options in the first quarter of 2004 resulting in proceeds to us of $1,857. The exercise of the remaining vested options could result in an inflow of cash in future periods.

Contractual Commitments

We have entered into various contracts, which have resulted in significant cash obligations in future periods. Such cash obligations could vary in future periods if we change our business plan or strategy, which could include significant additions to our programming, infrastructure or distribution. The following table summarizes our expected cash contractual commitments as of March 31, 2004:

	2004		2005		2006		2007		2008		Thereafter		Total

Long-Term Debt Obligations

Long-term debt obligations include principal and interest payments. As of March 31, 2004, we had $428,452 in aggregate principal amount of outstanding debt, consisting of $29,200 in aggregate principal amount at maturity of our 15% Senior Secured Discount Notes due 2007, $30,258 in aggregate principal amount of our 14½% Senior Secured Notes due 2009, $67,250 in aggregate principal amount of our 3½% Convertible Notes due 2008, $1,744 in aggregate principal amount of our 8¾% Convertible Subordinated Notes due 2009 and $300,000 in aggregate principal amount of our 2½% Convertible Notes due 2009.

Operating Leases

We have entered into operating leases related to our national broadcast studio, office space, terrestrial repeater sites and equipment.

Satellite and Transmission

We have entered into an agreement with a provider of satellite services to operate our off-site satellite telemetry, tracking and control facilities.

Programming and Content

We have entered into agreements with licensors of music and non-music programming and, in certain instances, are obligated to pay license fees, guarantee minimum advertising revenue share or purchase advertising on properties owned or controlled by these licensors. In addition, we have agreements with various rights organizations pursuant to which we pay royalties for public performances of music. In January 2004, we signed a seven-year agreement with the National Football League to broadcast NFL games live nationwide, and to become the Official Satellite Radio Partner of the National Football League, with exclusive rights to use the NFL “shield” logo and collective NFL team trademarks. We have agreed to pay the NFL an aggregate of $188,000 in cash during the term of the agreement. $10,000 of this amount was paid in connection with the announcement and execution of our agreement with the NFL and $85,000 was deposited in escrow to pay rights fees for the 2006-09 NFL seasons. The $85,000 deposited in escrow is included in restricted investments on our consolidated balance sheets and is not included as a contractual commitment in the table above.

Customer Service and Billing

We have entered into agreements with third parties to provide customer service, billing and subscriber management services.

Marketing and Distribution

Chip Set Development and Production

We have entered into an agreement with Agere to develop and produce chip sets for use in SIRIUS radios. This agreement requires Agere to manufacture a minimum quantity of chip sets during each year of the agreement. In April 2004, we executed an agreement with STMicroelectronics, one of the largest suppliers of integrated circuits in the world, to produce and integrate our next generation chip set. This agreement requires us to purchase a minimum of 1,500,000 chip sets during a three-year period for an aggregate price of approximately $20,000, and pay for the development of the chips as milestones are satisfied. Such contractual commitments are not included in the table of cash contractual obligations as of March 31, 2004 but will impact our cash obligation in future periods.

Joint Development Agreement

Other Commitments

We have agreed to use reasonable efforts to assist certain manufacturers of SIRIUS radios and components for those radios in the event that production of such radios and components are greater than sales. In certain circumstances, these reasonable efforts may include the purchase of unsold SIRIUS radios or components. In addition to the contractual commitments described above, we have also entered into agreements with automakers, radio manufacturers and others that include per-radio and per-subscriber required payments and revenue sharing arrangements. These future costs are dependent upon many factors and are difficult to anticipate; however, these costs may be substantial. We may enter into additional programming, marketing and other agreements that contain provisions similar to our current agreements.

We are required under the terms of certain agreements to provide letters of credit which place restrictions on our cash and cash equivalents. As of March 31, 2004 and December 31, 2003, $7,116 and $8,747, respectively, were classified as restricted investments to secure our reimbursement obligations under these letters of credit.

We have not entered into any off-balance sheet arrangements or transactions.

Critical Accounting Policies and Estimates

Our consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States, which require management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the periods. We have disclosed all significant accounting policies in note 3 to the consolidated financial statements included in this report. We have identified the following policies, which were discussed with the audit committee of our board of directors, as critical to our business and understanding our results of operations.

Subscription Revenue Recognition. Revenue from subscribers consists of subscription fees, including revenue derived from our agreement with Hertz, and non-refundable activation fees. We recognize subscription fees as our service is provided. Activation fees are recognized ratably over the term of the 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 additional historical data becomes available. As required by Emerging Issues Task Force 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 subscription revenue in the period the subscriber activates our service.

Stock-Based Compensation. In accordance with Accounting Principles Board (“APB”) Opinion No. 25, “Accounting for Stock Issued to Employees,” we use the intrinsic value method to measure the compensation costs of stock-based awards granted to employees. Accordingly, we record non-cash compensation expense for stock-based awards granted to employees and directors over the vesting period equal to the excess of the market price of the underlying common stock at the date of grant over the exercise price of the stock-based award. The intrinsic value of restricted stock units as of the date of grant is amortized to non-cash stock compensation expense over the vesting period. To the extent any performance criteria are satisfied and the vesting of any stock options and/or restricted stock units accelerate, the unamortized non-cash stock compensation expense associated with these options or restricted stock units is also accelerated.

In accordance with Emerging Issues Task Force 96-18, “Accounting for Equity Instruments That are Issued to Other Than Employees for Acquiring, or in Conjunction with Selling, Goods or Services,” we record expense based upon performance and the fair value of equity instruments issued to other than employees at each reporting date. The final measurement date of equity instruments is the date that each performance commitment for such equity instrument is satisfied. These costs are classified in our accompanying statements of operations according to the nature of the services performed.

Subscriber Acquisition Costs. Subscriber acquisition costs include incentives to purchase, install and activate SIRIUS radios as well as subsidies paid to radio manufacturers, automakers and retailers and payments to Agere for chip set production. Certain 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 sharing payments to manufacturers of SIRIUS radios. Subscriber acquisition costs are expensed as incurred. We retain ownership of the SIRIUS radios used in our agreement with Hertz; as a result, amounts capitalized in connection with this program are not included in our subscriber acquisition costs.

We have an agreement with Agere to develop and produce chip sets for use in SIRIUS radios. This agreement requires Agere to manufacture a minimum quantity of chip sets during each year of the agreement, and requires us to pay Agere fixed monthly payments. These costs are allocated between research and development and subscriber acquisition costs for development work and chip set production. Costs allocated to chip set production are expensed as subscriber acquisition costs when the chip sets are shipped to radio manufacturers. Chip sets that are shipped to us are recorded as inventory and expensed as subscriber acquisition costs when shipped to radio manufacturers.

Long-Lived Assets. We carry our long-lived assets at cost less accumulated depreciation. In accordance with SFAS No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets,” we review our long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset is not recoverable. At such time as an impairment in value of a long-lived asset is identified, the impairment will be measured as the amount by which the carrying amount of a long-lived asset exceeds its fair value. To determine fair value we would employ an expected present value technique, which utilizes multiple cash flow scenarios that reflect the range of possible outcomes and an appropriate discount rate.

Useful Life of Satellite System. Our satellite system includes the cost of satellite construction, launch vehicles, launch insurance, capitalized interest, our spare satellite and our terrestrial repeater network. In accordance with SFAS No. 144, we monitor our satellites for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset is not recoverable. The expected useful lives of our in-orbit satellites are fifteen years from the date they were placed into orbit. We are depreciating our three in-orbit satellites over their respective remaining useful lives beginning February 14, 2002 or, in the case of our spare satellite, from the date it was delivered to ground storage in April 2002. If placed into orbit, our spare satellite is expected to operate effectively for fifteen years. Space Systems/Loral, the manufacturer of our satellites, has identified circuit failures in solar arrays on satellites since 1997, including our satellites. We continue to monitor these failures, which we believe have not affected the expected useful lives of our satellites. If events or circumstances indicate that the useful lives of our satellites have changed, we will modify the depreciable life accordingly.

FCC License. We carry our FCC license at cost. Our FCC license has an indefinite life and will be evaluated for impairment on an annual basis or more frequently if there were indicators of impairment. In accordance with SFAS No. 142, “Goodwill and Other Intangible Assets,” we completed an impairment analysis of our FCC license on November 1, 2003, and determined that there was no impairment. We use projections regarding estimated future cash flows and other factors in assessing the fair value of our FCC license. If these estimates or projections change in the future, we may be required to record an impairment charge related to our FCC license.

Item 4. Controls and Procedures

As of March 31, 2004, an evaluation was performed under the supervision and with the participation of our management, including Joseph P. Clayton, 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 and control 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 March 31, 2004. There have been no significant changes in our internal controls or in other factors that could significantly affect these internal controls subsequent to March 31, 2004.

Other Information

Item 2. Changes in Securities, Use of Proceeds and Issuer Purchases of Equity Securities

On February 20, 2004, we sold $250,000,000 in aggregate principal amount of our 2½% Convertible Notes due 2009 to Morgan Stanley & Co. Incorporated, as initial purchaser. On March 31, 2004, we sold an additional $50,000,000 in aggregate principal amount of our 2½% Convertible Notes due 2009 to Morgan Stanley & Co. Incorporated pursuant to an option granted to the initial purchaser in connection with the initial offering.

The 2½% Convertible Notes due 2009 were offered and sold only to qualified institutional buyers in compliance with Rule 144A under the Securities Act. We did not sell the 2½% Convertible Notes due 2009 by any form of general solicitation or general advertising. In connection with the sale of the 2½% Convertible Notes due 2009, we paid an aggregate of $6,150,000 in discounts and fees to Morgan Stanley & Co. Incorporated. The proceeds from the sale of the 2½% Convertible Notes due 2009 will be used for general corporate purposes, including investments in programming and infrastructure, such as satellites, equipment and radio spectrum, and to pay the costs of retail and automotive distribution arrangements.

The following table contains information relating to our purchases of our equity securities during the three months ended March 31, 2004:

Period		Total Number of Shares (or Units) Purchased		Average Price Paid per Share (or Unit)		Total Number of Shares (or Units) Purchased as Part of Publicly Announced Plans or Programs		Maximum Number (or Approximate Dollar Value) of Shares (or Units) that May Yet Be Purchased Under the Plans or Program

All of the purchases of our 3½% Convertible Notes due 2008 during the three months ended March 31, 2004 were made as part of negotiated transactions in which the notes were exchanged for shares of our common stock in transactions exempt pursuant to Section 3(a)(9) of the Securities Act. We have not announced any plans or programs to repurchase any of our equity securities. We may from time to time purchase all or a portion of our outstanding 2½% Convertible Notes due 2009, 3½% Convertible Notes due 2008 or 8¾% Convertible Subordinated Notes due 2009 in negotiated transactions.
