Forward-Looking Statements

We include certain estimates, projections and other forward-looking statements in our annual, quarterly and current reports, and in other publicly available material. Statements regarding expectations, including performance assumptions and estimates relating to capital requirements, as well as other statements that are not historical facts, are forward-looking statements.

These statements reflect management's judgments based on currently available information and involve a number of risks and uncertainties that could cause actual results to differ materially from those in the forward-looking statements. With respect to these forward-looking statements, management has made assumptions regarding, among other things, customer and network usage, customer growth and retention, pricing, operating costs, the timing of various events and the economic and regulatory environment.

Future performance cannot be assured. Actual results may differ materially from those in the forward-looking statements. Some factors that could cause actual results to differ include:

Overview

We are a global communications company offering a comprehensive range of wireless and wireline communications products and services that are designed to meet the needs of individual consumers, businesses and government customers. We have organized our operations to meet the needs of our targeted customer groups through focused communications solutions that incorporate the capabilities of our wireless and wireline services to meet their specific needs. We are one of the three largest wireless companies in the United States based on the number of wireless subscribers. We also are one of the largest providers of Wireline long distance services and one of the largest carriers of Internet traffic in the nation. We own extensive wireless networks and a global long distance, Tier 1 Internet backbone.

In December 2007, Daniel R. Hesse joined our company as President and Chief Executive Officer. Senior management is currently assessing our business model, associated sales, distribution and marketing plans and financial outlook. This process is still ongoing and, depending on the outcome, our operations, future capital requirements and the recoverability of our long-lived assets could be affected. As part of our overall business strategy, we regularly evaluate opportunities to strengthen our business and may at any time be discussing or negotiating a transaction that, if consummated, could have a material effect on our business, financial condition, liquidity or results of operations. As a result, the forward-looking information provided in this document is based only on the information currently available to our senior management.

We believe the communications industry has been and will continue to be highly competitive on the basis of price, the types of services and devices offered and quality of service. Although we believe that many of our targeted customers base their purchase decisions on quality of service and the availability of differentiated features and services, competitive pricing, both in terms of the monthly recurring charges and the number of minutes or other features available under a particular rate plan, and handset offerings and pricing are often important factors in potential customers' purchase decisions.

The FCC regulates the licensing, operation, acquisition and sale of the licensed radio spectrum that is essential to our business. The FCC and state Public Utilities Commissions also regulate the provision of

Business Segments

We have two reportable segments: Wireless and Wireline. See note 8 of the Notes to Consolidated Financial Statements for additional information on our segments.

Wireless

Products and Services

Our strategy is to utilize state-of-the-art technology to provide differentiated wireless services and applications in order to acquire and retain high-quality wireless subscribers. We offer a wide array of wireless mobile telephone and wireless data transmission services on networks that utilize CDMA and iDEN technologies to meet the needs of individual consumers, businesses and government customers.

Through our Wireless segment, we, together with the PCS Affiliates and resellers of our wholesale wireless services, offer digital wireless service in all 50 states, Puerto Rico and the U.S. Virgin Islands, providing wireless coverage in 364 metropolitan markets, including 345 of the 349 largest U.S. metropolitan areas, and serving about 53 million wireless subscribers as of March 31, 2008. We offer wireless international voice roaming for subscribers of both CDMA and iDEN-based services in numerous countries. Our CDMA network utilizes high-speed evolution data optimized, or EV-DO, technology to provide high-speed data applications. We have incorporated EV-DO Rev. A, the most recent version of EV-DO technology that is designed to support a variety of internet protocol, or IP, video and high performance walkie-talkie applications, into over 84% of our CDMA network.

We offer a wide array of wireless mobile telephone and data transmission services and features in a variety of pricing plans, typically on a contract basis, for one or two year periods. Services are billed on a monthly basis according to the applicable pricing plan, which typically includes a fixed charge for certain services and variable charges for other services. We also offer wireless services that focus on the youth market, including our Boost Mobile prepaid wireless service on our iDEN network and our Boost UnlimitedSM local calling wireless service on our CDMA network. We also offer wholesale CDMA-based wireless services to resellers, commonly known as mobile virtual network operators, or MVNOs, which purchase wireless services from us at wholesale rates and resell the services to their customers under their own brand names. Under these MVNO arrangements, the operators bear the costs of subscriber acquisition, billing and customer service. In light of current industry conditions, it is possible that our MVNOs may reevaluate their long-term business strategies.

We offer a broad portfolio of data services across our CDMA network, including data messaging, photo and video offerings, entertainment and location-based applications, marketed as Power VisionSM, and mobile broadband applications for laptops and other devices.

On our iDEN network, we continue to support features and services designed to meet the needs of our customers. Both the Nextel and prepaid Boost Mobile brands feature our industry-leading walkie-talkie services, which give subscribers the ability to communicate instantly across the continental United States and to and from Hawaii and, through agreements with other iDEN providers, to and from select markets in Canada, Latin America and Mexico, as well as a variety of digital wireless mobile telephone and wireless data transmission services. We offer some data services on the iDEN network, but that network does not support a full complement of data services and many of those services are available only with limited capabilities. In addition, we are also improving our product and service offerings on our iDEN network, including the introduction of several new handsets throughout 2008.

We plan to utilize QUALCOMM Incorporated's QChatฎ technology, which is designed to provide high performance walkie-talkie services on our CDMA network, and we are designing interfaces to provide for

Service Revenue

Our Wireless segment generates revenues from the provision of wireless services, the sale of wireless equipment and the provision of wholesale and other services. The ability of our Wireless segment to generate service revenues is primarily a function of:

• the number of subscribers that we serve, which in turn is a function of our ability to acquire new and retain existing subscribers; and

• the revenue generated from each subscriber, which in turn is a function of the types and amount of services utilized by each subscriber and the rates that we charge for those services.

The declines in our subscriber base and revenue generated from each subscriber group discussed below have resulted in a decline in service revenue.

Post-Paid and Prepaid Subscribers

The wireless industry is subject to intense competition, which impacts our ability to attract and retain subscribers for wireless services. Most markets in which we operate have very high rates of penetration for wireless services, which will limit the growth of subscribers of wireless services. Consequently, we believe that wireless carriers must attract a greater proportion of new subscribers from the existing customer bases of competitors rather than from first time purchasers of wireless services. Because of high penetration rates, first time purchasers of wireless services tend to have lower credit ratings or no credit history. As a result, wireless carriers have focused considerable efforts on the care and service of existing subscribers and retention of valued customers. Some of our competitors have reported significant improvements in their post-paid customer retention rates (i.e., rates of customer churn). The combination of decreased rates of churn of some of our competitors, together with a slowing in the rate of subscriber growth, has reduced the pool of potential subscribers making wireless service provider decisions.

(1) Includes subscribers with PowerSource devices.

(2) During the third quarter 2007, we implemented an additional churn rule to remove the impact of activations and deactivations occurring within 30 days in the same account. The new rule, which we believe presents a more precise churn calculation, reduced churn by 10 basis points to 2.3% in the third quarter 2007. The additional churn rule did not impact reported net additions or results of operations. Prior period churn figures have not been adjusted for this additional churn rule.

Throughout 2007 and in the first quarter 2008, we endeavored to retain subscribers and attract new subscribers by continuing our focus on improving our customer care and sales and distribution functions and endeavoring to improve our customers' experience. In addition, on February 28, 2008 we launched a new rate plan, known as "Simply Everything," which offers customers unlimited domestic talking, web surfing, emailing, direct connect, domestic texting, video and picture sharing for $99.99 per month. We also broadened our handset portfolio primarily through the introduction of new CDMA handsets, and lowered the price of certain iDEN handsets.

Despite our efforts, we lost 386,000 net post-paid subscribers on the CDMA network and 684,000 net post-paid subscribers on the iDEN network during the first quarter 2008. The subscriber losses were due in part to a decline in new post-paid subscribers caused primarily by increased advertising and promotions by our competitors compared to ours and a maturing wireless telecommunications market. In addition, customer sentiment regarding our networks, customer care and recent adjustments to our credit policies have contributed to the decline in the number of new subscribers. We continually monitor and adjust our credit policies in an effort to attract desirable and profitable customers, including our lower credit quality customers.

We calculate churn by dividing net subscriber deactivations for the quarter by the sum of the average number of subscribers for each month in the quarter. For accounts comprised of multiple subscribers, such as family plans and enterprise accounts, net deactivations are defined as deactivations in excess of customer activations in a particular account within 30 days. Post-paid churn consists of both voluntary churn, where the subscriber makes his or her own determination to cease being a customer, and involuntary churn, where we terminate the customer's service due to a lack of payment or other reasons. Post-paid churn increased in the first quarter 2008 as compared to the fourth quarter 2007 primarily due to an increase in post-paid churn on our CDMA platform. Voluntary churn on both networks has been adversely impacted by customer sentiment related to the network and the customer care experience as well as competitors' offerings. In recent periods, voluntary churn on the iDEN network has also been adversely impacted by limited handset offerings, at higher than market prices. Our overall 2008 post-paid churn remains high relative to that of our competitors for the reasons discussed above. Prepaid churn related to traditional prepaid users also increased in the first quarter 2008 due to the elimination of certain retention efforts and more aggressive prepaid marketing by other national carriers. The churn rate for Boost Unlimited users improved modestly from the fourth quarter 2007. Refer to "-Results of Operations-Segment Results of Operations-Wireless-Wireless Segment Earnings" below for a discussion of subscriber trends.

Average Revenue per Subscriber

Below is a table showing our average revenue per post-paid and prepaid
subscriber for each quarter beginning with the first quarter 2007.

Average monthly service revenue per subscriber for the quarter is calculated by dividing our quarterly service revenue by the sum of our average number of subscribers for each month in the quarter. Changes in average monthly post-paid service revenue are due to changes in the rate plans we offer and usage of our service and applications by subscribers. The decline in our average monthly voice revenue is primarily due to the loss of subscribers with higher priced service plans, while new subscribers have lower priced service plans and existing subscribers are migrating to lower priced, volume based or bundled pricing plans such as family add-on plans. Our average monthly service revenue is also impacted by service credits that we offer our customers, which have increased recently as part of our retention efforts. In addition to our standard voice plans, we offer data plans or add on plans that provide our customers offerings such as short message service, or SMS, connection cards and our Sprint Vision and Power Vision service plans. As these products and services are becoming increasingly popular with our customers, the decline in the average voice revenue per subscriber is being partially offset by an increase in the average data revenue per post-paid subscriber. There is no assurance that data service revenue per subscriber will continue to grow at current rates or eventually offset the declines in voice revenue.

Segment Earnings

Wireless segment earnings is primarily a function of wireless service revenue, costs to acquire subscribers, network and interconnection costs to serve those subscribers and other Wireless segment operating expenses. The costs to acquire our customers include the net cost at which we sell our handsets, referred to as handset subsidies, as well as the marketing and sales costs incurred to attract those customers. Network costs primarily represent switch and cell site costs and interconnection costs generally consist of per-minute use fees and roaming fees

Legislative and Regulatory Developments

800 Megahertz Spectrum Reconfiguration

Under the FCC's Report and Order, we are required to complete a reconfiguration plan that is designed to eliminate interference with public safety operators in the 800 MHz spectrum band through a spectrum reallocation that will result in more efficient use of 800 MHz spectrum. For a more detailed discussion of the Report and Order and its impact on us, refer to Item 1. "Business-Legislative and Regulatory Developments-Regulations and Wireless Operations-800 MHz Band Spectrum Reconfiguration" in our annual report on Form 10-K for the year ended December 31, 2007.

The Report and Order implemented rules to reconfigure spectrum in the 800 MHz band in a 36-month phased transition process. We surrendered certain portions of our holdings in the 800 MHz spectrum band and are obligated to fund the cost incurred by public safety systems and other incumbent licensees to reconfigure the 800 MHz spectrum band. As part of this process, in most markets, we must cease using portions of 800 MHz spectrum during the reconfiguration before we are able to commence use of replacement 800 MHz spectrum. Based on the terms of the Report and Order and subsequent FCC and 800 MHz Transition Administrator, or TA, actions, we have been planning and implementing spectrum exchanges with each affected public safety agency based upon that agency's plan to complete the reconfiguration process, thereby limiting the time from when we cease using the surrendered spectrum and when the replacement spectrum is available for our use. In September 2007, the FCC issued an order, the Third Memorandum Opinion and Order, or Third MO&O, that, among other things, requires that by June 2008 we vacate many 800 MHz channels that we currently use, even if the applicable public safety licensee is not ready to relocate to the vacated spectrum, which could result in a sudden and significant decrease in network capacity, which in turn would adversely affect the performance of our iDEN network. We appealed this order in the U.S. Court of Appeals for the D.C. Circuit. On May 2, 2008, the Court affirmed the FCC's decision in the Third MO&O. While we are still evaluating the impact of this decision, we remain committed to identifying a resolution to this matter that balances achieving the goals of 800 MHz reconfiguration with meeting the mobile communications needs of our customers.

If this order is not overturned or modified, we could attempt to construct additional sites or acquire additional spectrum, to the extent possible. In those markets where these network investments are not possible, we may be required to curtail subscriber additions and/or incentivize certain existing subscribers of iDEN services to use PowerSource devices or move to our CDMA . . .
