The following discussion of our financial condition and results of operations should be read in conjunction with our unaudited financial statements for the three and nine months ended September 30, 2008 and 2007 and the notes thereto included elsewhere herein and with our annual report on Form 10-K for the year ended December 31, 2007, filed with the Securities and Exchange Commission in March 2008. This discussion contains forward-looking statements that are subject to known and unknown risks and uncertainties, including those discussed in Item 1A, "Risk Factors," in Part II.

Unless we state otherwise or the context otherwise requires the terms (1) "we", "us" and "our" refer to Virgin Mobile USA, Inc., and its consolidated subsidiaries; (2) "Sprint Nextel" refers to Sprint Nextel Corporation, a Kansas corporation, and its affiliated entities; (3) the "Virgin Group" refers to Virgin Group Holdings Limited, a British Virgin Islands company and its affiliated entities; and (4) "SK Telecom" refers to SK Telecom USA Holdings, Inc. and its affiliated entities.

Introduction

We are a Delaware corporation formed in April 2007 as a holding company for the purpose of facilitating an initial public offering, or IPO, of Class A common stock, which was completed on October 16, 2007. Prior to the completion of the IPO, Virgin Mobile USA, Inc. and its subsidiaries completed reorganization transactions, or the Reorganization, pursuant to which Virgin Mobile USA, LLC, the principal operating entity for our business, converted into a Delaware limited partnership, changed its name to Virgin Mobile USA, L.P., and became a majority-owned subsidiary of Virgin Mobile USA, Inc., the holding company for the public's common equity interests in our business.

We have accounted for the Reorganization for periods prior to the completion of the IPO using a carryover basis, similar to a pooling-of-interest, because the reorganization transactions were premised on a non-substantive exchange in order to facilitate the IPO resulting in the retention of historical based accounting. This is consistent with Financial Accounting Standards Board Technical Bulletin 85-5, Issues Relating to Accounting for Business Combinations, including Costs of Closing Duplicate Facilities of an Acquirer; Stock Transactions between Companies under Common Control; Down-Stream Mergers, Identical Common Shares for a Pooling of Interests; and Pooling of Interests by Mutual and Cooperative Enterprises. Under this method of accounting, the companies are treated as if they had always been combined for accounting and financial reporting purposes and, therefore, the condensed consolidated financial statements for the three and nine months ended September 30, 2007 are presented on the same basis as those for the three and nine months ended September 30, 2008. We began recording minority interest associated with Sprint Nextel's ownership in Virgin Mobile USA, L.P. during the three months ended June 30, 2008 because we had cumulative earnings since the date of the reorganization. We present minority interest in a manner consistent with Emerging Issues Task Force Issue No. 94-2, Treatment of Minority Interests in Certain Real Estate Investment Trusts.

Company Overview

We are a leading national provider of wireless communications services, offering prepaid, or pay-as-you-go, and, following the acquisition of Helio LLC, postpaid services targeted at the youth market. Our customers are attracted to our products and services because of our flexible terms, easy to understand and value-oriented pricing structures, stylish handsets offered at affordable prices and relevant mobile data and entertainment content. Our prepaid product and service offerings have no annual contract or credit check and we attract a wide range of customers. Approximately half of our current customers are ages 35 and over. Our voice and data plans allow our customers to talk, use text messaging, picture messaging and email on a per usage basis or according to the terms of our monthly plans. Following the acquisition of Helio LLC, or Helio, on August 22, 2008, we began to offer additional voice and data plans, some with two-year contracts, for both individual and family plans.

We were founded as a joint venture between Sprint Nextel and the Virgin Group and launched our service nationally in July 2002. As of September 30, 2008, we served 5.2 million customers, an increase of 5.9% over the 4.9 million customers served at September 30, 2007 and an increase of 1.5% compared to the 5.1 million customers served at December 31, 2007. On August 22, 2008 we acquired Helio, a provider of postpaid wireless products and services, with a customer base of approximately 170 thousand. The acquisition of Helio allowed us to offer high-value postpaid services and to acquire a unique and differentiated set of data applications that we expect to offer across our customer base. In addition, in connection with the acquisition of Helio, we: (i) revised the terms of the our PCS Services Agreement with Sprint Nextel, which we currently expect will reduce our effective network cost per minute in 2009; (ii) received additional investments of $25 million from each

of Virgin Group and SK Telecom, in exchange for our issuance of Series A convertible Preferred Stock, or the Preferred Stock; (iii) increased the borrowing availability under our subordinated secured revolving credit facility, or Revolving Credit Facility, from $75 million to $135 million, through additional commitments of $25 million by Virgin Group and $35 million by SK Telecom; and (iv) added SK Telecom as a strategic stockholder entitled to two seats on the Company's Board of Directors.

We market our products and services under the "Virgin Mobile" and the "Helio" brands using the nationwide Sprint PCS network. We control our customers' experience and all customer "touch points," including brand image, web site, retail merchandising, service and product pricing, mobile content options, marketing, distribution and customer care, but as a mobile virtual network operator, or MVNO, we do not own or operate a physical network, which frees us from related capital expenditures. This allows us to focus our resources and compete effectively against the major national wireless providers in our target market. We focus primarily on wireless consumers who use 200 to 1,200 minutes per month, which we estimate encompasses 80% of all wireless consumers. Our cost of service for wireless network services is based on fixed rates set forth in the Fifth Amendment to our PCS Services Agreement with Sprint Nextel, described below. We expect this to reduce volatility in our network costs and secure decreasing per-user costs for the duration of the PCS Services Agreement.

On June 27, 2008, we entered into the Fifth Amendment to the PCS Services Agreement, which became effective with the closing of the Helio acquisition and provides that we will pay Sprint Nextel at least $320 million, $370 million and $420 million, during the years ending December 31, 2008, 2009 and 2010, respectively, for wireless network services, including voice, messaging and data traffic. Additionally, the Fifth Amendment provides that as of July 1, 2008, Sprint Nextel will pay us a $2.50 network usage credit for each gross additional customer through December 31, 2009, up to a maximum of $10 million.

Prior to July 2008, every three years each of Sprint Nextel's third-party PCS affiliates had the right to discontinue the activation of service for our new customers in their respective regions, but two of the remaining three affiliates have now agreed to provide services to Virgin Mobile through the expiration of our PCS Services Agreement with Sprint Nextel (unless their relationship with Sprint Nextel terminates before that time). During the nine months ended September 30, 2008, 5.3% of our customers accessed our services through Sprint Nextel's third-party PCS affiliates, and we generated approximately $35 million in revenues from such customers.

We operate in the highly competitive and regulated wireless communications industry. The primary bases of competition in our industry are the prices, types and quality of products and services offered. As the wireless communications industry continues to grow and consolidate, we continually reassess our business strategies and their impact on our operations. Our strategies have included pricing our handsets competitively to grow and maintain our customer base. We expect these strategies to continue in the future. As a result, handset subsidies may increase and could result in lower results of operations and cash flows. In addition, lower handset prices may increase the number of subsidized replacement handsets sold to existing customers at a loss as customers replace their existing handsets, resulting in additional cost to our business which would have an adverse impact on our results of operations and cash flows.

The lower handset prices may also make our services more accessible to new lower-value customers with less disposable income available to spend on our services. In addition, as handset prices decline and handsets become more disposable, customers without long-term contracts may change their wireless providers more frequently, thereby increasing our customer turnover, or churn, and resulting in additional acquisition costs to replace those customers. Depending on how quickly a customer churns, we may not be able to recoup our initial investment expended in acquiring the customer. A shift to lower value or less stable customers could have an adverse impact on our financial position, results of operations and cash flows. Reduced revenues as a result of such a shift would also reduce our working capital for planned retail distribution improvements, otherwise hinder our ability to improve our stock performance and might necessitate cost saving measures.

We continually monitor the impact of handset prices on the profile of our new customers, the behavior of our existing customers and our financial performance. We will make adjustments to our pricing strategy accordingly, including potentially raising prices.

We primarily rely on four third-party retail distribution channels for product placement within their stores to promote the sale of our handsets to grow our customer base. Our relationships with these distribution partners are strong and we expect the relationships to continue. However, there is no assurance that our distribution partners will continue to distribute our products. The loss of any of these four retail distribution partners could result in lower gross additions, account replenishments, or "Top-Ups", and increased churn and therefore lower results of operations and cash flows. In the first half of 2008, we entered into

three agreements to expand our retail presence. We entered new agreements with American Wireless and Sears and expanded our relationship with Wal-Mart. Collectively, these arrangements are expected to expand our retail footprint by more than 2,000 doors by year end 2008.

The Federal Communications Commission, or FCC, and state Public Utilities Commissions, or state PUCs, regulate the provision of communication services. Future changes in regulations and compliance could impose significant additional costs on us either in the form of direct out-of-pocket costs or additional compliance obligations. We could be forced to increase our rates to cover these costs, making our service pricing less attractive to customers.

We earn revenues primarily from the sale of wireless voice and mobile data services, along with the sale of handsets through third party retail locations, our website or call center. Our services are available through a variety of different pricing plans, including flat rate and monthly plans that offer the benefits of long-term contract-based wireless plans with the flexibility of pay-as-you-go services. Following the acquisition of Helio on August 22, 2008, we began to offer additional voice and data plans, some with two-year contracts, for both individual and family plans. During the first half of 2008, we rolled out new pricing plans, all of which were fully deployed by June 30, 2008. These plans were designed to simplify the competitiveness and value of our offers to our customers. These new plans provide our customers the ability to purchase, in a variety of ways and on a flexible basis, packages of minutes, or minute packs, in denominations ranging from $20 to $50. They also include, subject to certain restrictions, a roll-forward feature for previously purchased minutes. On July 1, 2008, we further revised our calling plans by unveiling our "Totally Unlimited" nationwide calling plan for $79.99 per month, with no roaming or long-distance charges. We believe that the flexibility and competitive price points on these plans will help us retain customers and stimulate growth. We expect these new monthly plans to contribute an increasing portion of our revenue going forward.

We continue to assess the various competitive offers and pricing actions in the marketplace and will continue to monitor the offers and pricing actions our competitors take to assure that our offers remain competitive.

From time to time, we evaluate strategic opportunities, including mergers and acquisitions, partnerships and co-marketing opportunities, to improve our products and services, accelerate growth and increase stockholder value. Prior to our acquisition of Helio, we had grown our business organically, but, subject to existing and future contractual obligations, we may continue to consider mergers, acquisitions and strategic investments from time to time that enable us to achieve greater scale, cost or technology advantages.

The United States economy and capital markets are currently undergoing a period of unprecedented volatility which may lead to a recession. Our management expects that if the economic environment continues to be unfavorable in comparison to the prior years in which we have operated and negatively affects consumer spending, our handset and data sales, usage rates and results of operations will be adversely affected. In such circumstances, we and our competitors might be compelled to offer our products and services at promotional prices, which may have a negative impact on operating income. Reduced revenues as a result of decreased consumer spending would also reduce our working capital for planned retail distribution improvements, otherwise hinder our ability to improve our stock performance and might necessitate cost saving measures.

Acquisition of Helio LLC

On August 22, 2008, we acquired Helio, a provider of wireless products and services, at which time Helio became a wholly owned subsidiary of Virgin Mobile USA, L.P. The acquisition of Helio is expected to facilitate our entry into postpaid offerings and allow us to take advantage of Helio's proprietary technology.

Under the terms of the agreement to acquire Helio, we acquired Helio from SK Telecom, EarthLink, Inc., or EarthLink, and Helio, Inc. in exchange for 12,806,632 limited partnership units in Virgin Mobile USA, L.P. and 193,368 shares our Class A common stock, together equivalent to 13 million shares of our Class A common stock. Each of the newly issued Virgin Mobile USA, L.P. partnership units is convertible into shares of our Class A common stock on a one-for-one basis. The purchase price, based on the average closing price of our Class A common stock two trading days before and ending two trading days after the date of the announcement, is $41.3 million, including $3.7 million direct costs of the acquisition. The issuance of ownership units by Virgin Mobile USA, L.P. reduced our ownership interest in the accumulated deficit of Virgin Mobile USA, L.P. from 81.6% before the issuance of ownership units to 68.3% after the issuance. We recorded a $37.1 million gain on the issuance of the common units by Virgin Mobile USA, L.P. and reflected it in additional paid-in-capital in accordance with Staff Accounting Bulletin No. 51, Accounting for Sales of Stock of a Subsidiary.

Subject to approval by our stockholders, each of SK Telecom and EarthLink will be issued one share of Class B common stock. Each of these shares will entitle its recipient to a number of votes on all matters submitted to a vote of stockholders that is equal to the total number of shares of Class A common stock for which the partnership units that its owner holds in Virgin Mobile USA, L.P. are exchangeable.

In connection with the acquisition of Helio, we recorded a restructuring reserve for the closure of Helio's sales offices, kiosks, and stores, along with one-time benefits for certain employees of Helio who were terminated. For the three months ended September 30, 2008, we recorded expenses of $295 thousand, included in restructuring expenses, for one-time employee termination benefits for those employees who will assist with the integration of Helio into our business. We anticipate the remainder of the charges will be approximately $0.6 million for the three months ended December 31, 2008 and approximately $0.3 million in 2009. We anticipate the cash payments related to the Helio restructuring activities will be approximately $5.8 million in 2008 and approximately $2.5 million in 2009.

On August 22, 2008, in connection with the acquisition of Helio, we issued 50,000 shares of Preferred Stock with 25,000 shares issued to the Virgin Group and 25,000 shares issued to SK Telecom. The Preferred Stock was issued at the stated value of $1,000 per share, with proceeds to us of approximately $50 million. The Preferred Stock carries a cumulative 6% annual dividend payable semi-annually, which will be paid with additional shares of Preferred Stock at the stated value of $1,000 per share.

Subject to the approval by our the stockholders, each share of the Preferred Stock will be mandatorily convertible into 117.64706 shares of our Class A common stock at the earlier of (i) August 22, 2012 and (ii) such time as the market price of our Class A Common Stock exceeds $8.50 per share. Subject to approval by our stockholders, the Preferred Stock will also be convertible at the option of the holder on or after February 22, 2010, 18 months after the date of issuance. Should we fail to obtain stockholder approval of the conversion feature, the Preferred Stock will be mandatorily redeemed on August 22, 2012 at a redemption price equal to the stated value of $1,000 per share.

In connection with the acquisition of Helio, we entered into a Second Amendment to the Senior Credit Agreement and a Second Amendment to the Revolving Credit Facility. The Second Amendment to the Revolving Credit Facility increased the Virgin Group's lending commitment from $75 million to $100 million and added SK Telecom as a new lender with a lending commitment of $35 million. The Second Amendment to the Senior Credit Agreement (i) required that the $50 million of proceeds from the issuance of the Preferred Stock be used to pay down a portion of the outstanding loan balance under the Senior Credit Agreement,
(ii) increased the interest rate applicable to outstanding balances by 100 basis points per year, and (iii) tightened the leverage ratio covenant by 0.25 times (for the quarter ending December 31, 2008, the required leverage ratio decreases from 3.00:1.00 to 2.75:1.00).

IBM Outsourcing Agreement

On July 3, 2008, we signed an outsourcing agreement with IBM, or the IBM Agreement. We believe that outsourcing much of our information technology needs to IBM will enhance our technological capabilities and help to improve our product portfolio for new and existing customers. The IBM Agreement requires IBM to provide information technology services to us through May 15, 2013. We have the right, but not the obligation, to extend the IBM Agreement for one additional year, or to May 15, 2014, if certain conditions are met.

As part of the IBM Agreement, our information technology, infrastructure and applications development will be transitioned to IBM's service environment and 46 of our employees transferred to IBM on June 30, 2008. In connection with the outsourcing, 85 employees were terminated during the three months ended September 30, 2008, and approximately 30 employees are expected to be terminated during the three months ended December 31, 2008. In addition, we expect to close our facility in Walnut Creek, CA during the first quarter of 2009. Employees being terminated are required to remain with us through a specified transition period in order to be eligible to receive any one-time termination benefits. The outsourcing is expected to result in restructuring charges for one-time termination benefits, including severance, completion bonuses, retention bonuses, and the associated benefits and payroll taxes, contract termination fees, fixed asset related charges for disposals, and other charges during the second half of 2008 and year 2009. During the three months ended September 30, 2008, $6.2 million was recorded for the restructuring, primarily related to employee charges. During the three months ended December 31, 2008, we estimate the costs associated with the restructuring will be approximately $1.8 million and for the year ended December 31, 2009, we estimate costs associated with our restructuring activities will be approximately $2.7 million.

We expect cash payments to be approximately $4.6 million in the three months ended December 31, 2008 and $5.3 million for the year ended December 31, 2009. The transition of our information technology, infrastructure and applications development to the IBM service environment is expected to be completed by March 31, 2009. Beginning in 2009, we anticipate average annual savings of approximately $12 million.

In accordance with the IBM Agreement, we prepaid $7.7 million in service charges to IBM during the period July 2008 through September 2008 and are required to prepay an additional $2.4 million in service charges to IBM over the period from October 2008 to March 2009. The third quarter 2008 prepayments were paid from funds generated from operations which we expect will also be the source of funding for the remaining prepayments of $2.4 million. The prepayments have been, and will be, applied to charges for IBM services to us over the five-year term. The IBM Agreement calls for IBM to provide a baseline level of service according to an agreed-upon pricing schedule. We expect to incur the following charges, inclusive of the amortization of the prepayments discussed above, as follows (in thousands):

                                 Year     Amount
                                 2008    $   5,925
                                 2009       29,654
                                 2010       29,420
                                 2011       28,884
                                 2012       27,001
                                 2013        7,360

                                 Total   $ 128,244

The baseline services incurred are adjusted monthly to reflect changes in the underlying currencies of countries in which IBM provides services to us. In addition, beginning in January 2010, the baseline service payments above will be adjusted on a monthly basis to reflect inflation or deflation in the U.S. and other countries in proportion to the services that IBM provides from each country. We may increase or decrease the level of baseline services provided by IBM, along with related payments, based upon certain restrictions and circumstances. We expect to increase the baseline services for new applications development in the future.

Either party can terminate the IBM Agreement early under certain circumstances, but if we terminate the IBM Agreement solely for our convenience we will be required to pay certain termination fees and wind-down charges. The minimum termination fee that we would be obligated to pay if we terminate the IBM Agreement prior to January 2009 is approximately $13.9 million, which amount is scheduled to decrease over the life of the IBM Agreement. Wind-down charges are defined as non-cancelable lease payments, lease termination fees, certain salaries, benefits, relocation costs, severance costs relating to IBM employees that were our former employees, and certain other costs. Wind-down costs cannot be reasonably estimated at this time but could be material to our financial position if we elect to terminate the IBM Agreement.

Seasonality

Our business experiences significant seasonality that is driven by the traditional retail selling periods. We typically generate our highest level of gross additions in the fourth quarter of the year due to increased consumer spending during the holiday season. Additionally, our first quarter typically reflects a relatively low level of churn, due, in part, to the impact of the relatively high level of new customers added in the prior quarter and the way in which we measure our prepaid churn, as we do not consider a prepaid customer to have churned until there has been 150 days of account inactivity (for postpaid, except for returns within 30 days, the churn is recorded when the customer disconnects). As a result, our net customer additions are often favorably impacted in both the fourth quarter and the first quarter of the following year. In contrast, our net customer additions for the second and third quarters reflect both the lower level of gross additions in those periods as well as the higher churn, from the fourth quarter gross additions.

The seasonality of our customer acquisitions is reflected in our financial statements, whereby the higher subsidies in the third and fourth quarters to support the fourth quarter customer acquisition surge, resulting in a decline in our operating income and cash generated from operations during those quarters. The greater the number of customer acquisitions we are able to achieve in the latter part of the year, the greater the temporary negative impact on Adjusted EBITDA and cash generated from operations, although additional customers' future cash flows are expected to increase our value in the longer term. Our cost per gross addition, or CPGA, is typically the lowest in the fourth quarter, reflecting the seasonality of our gross additions.

Results of Operations

Key Performance Metrics

Our management utilizes the following key performance metrics used in the wireless communications industry to manage and assess our financial performance. These metrics include gross additions, churn, net customer additions, end-of-period customers, Adjusted EBITDA, Adjusted EBITDA margin, Average Revenue Per User, or ARPU, Cash Cost Per User, or CCPU, Cost Per Gross Addition, or CPGA, and Unlevered free cash flow (for information on Unlevered free cash flow see Liquidity and Capital Resources). Trends in key performance metrics such as ARPU, CCPU, and CPGA will depend upon the scale of our business as well as the dynamics in the marketplace and our success in implementing our strategies. The following table provides a summary of these key performance metrics for the periods indicated and the trends in each of these metrics are discussed below:
