General
     We offer wireless broadband personal communication services, or PCS, on a no long-term contract, flat rate, unlimited usage basis in selected major metropolitan markets in the United States. Since we launched our wireless service in 2002 we have been among the fastest growing wireless broadband PCS providers in the United States as measured by growth in subscribers and revenues. We reached one million customers in January 2004, 1.5 million customers in February 2005, two million customers in February 2006, 2.5 million customers in August 2006 and three million customers in January, 2007. We launched our service initially in 2002 in the Miami, Atlanta, Sacramento and San Francisco metropolitan areas, which we refer to as our Core Markets and which currently comprise our Core Markets segment. Beginning in the second half of 2004, we began to strategically acquire licenses in new geographic areas that share certain key characteristics with our existing Core Markets. These new geographic areas, which we refer to as our Expansion Markets and which currently comprise our Expansion Markets segment, include the Tampa/Sarasota, Dallas/Ft. Worth and Detroit metropolitan areas, as well as the Los Angeles and Orlando metropolitan areas and portions of northern Florida, which were acquired by Royal Street Communications, LLC, or Royal Street Communications. We currently offer our services in the greater San Francisco, Miami, Tampa/Sarasota/Orlando, Atlanta, Sacramento, Dallas-Ft. Worth, and Detroit metropolitan areas, which include a total licensed population of approximately 43 million. We launched service in the Miami, Atlanta and Sacramento metropolitan areas in the first quarter of 2002; in San Francisco in September 2002; in Tampa-Sarasota in October 2005; in Dallas-Fort Worth in March 2006; in Detroit in April 2006; and, through a wholesale arrangement with Royal Street Communications and Royal Street Communications with its wholly-owned operating and license subsidiaries, or Royal Street, in Orlando and portions of northern Florida in November 2006. In 2005,

Royal Street Communications, a company in which we own a non-controlling 85% limited liability company member interest, but only elect two of the five members of the management committee, was granted licenses by the Federal Communications Commission (“FCC”) for the Los Angeles basic trading area and various basic trading areas throughout northern Florida. Royal Street is in the process of building infrastructure in Los Angeles and expects to commence commercial service in the second or third quarter of 2007. We have a wholesale arrangement that will allow us to sell MetroPCS-branded service to the public on up to 85% of the service capacity provided by the Royal Street systems.
     Our wireless services target a mass market which we believe is largely underserved by traditional wireless carriers. Our service, branded under the “MetroPCS” name, allows customers to place unlimited local calls from within our service area, and to receive unlimited calls from any area while in our local service areas under simple and affordable flat monthly rate plans starting at $30 per month. For an additional $5 to $20 per month, our customers may select a service plan that offers additional services, such as the ability to place unlimited long distance calls from within our service area to any number in the continental United States, or unlimited voicemail, caller ID, call waiting, text messaging, mobile Internet browsing, push e-mail and picture and multimedia messaging. For additional fees, we also provide international long distance and text messaging, ringtones, ring back tones, downloads, games and content applications, unlimited directory assistance and other value-added services. Our customers also have access, on a prepaid basis, to nationwide roaming. Our rate plans differentiate our service from the more complex plans and long-term contracts required by most other traditional wireless carriers. Our customers pay for our service in advance, eliminating any customer-related credit exposure.
     As of December 31, 2006, our customers in all metropolitan areas averaged approximately 2,000 minutes of use per month, compared to approximately 875 minutes per month for customers of the national wireless carriers. We believe that average monthly usage by our customers also exceeds the average monthly usage for typical wireline customers. Average usage by our customers indicates that a substantial number of our customers use our services as their primary telecommunications service, and our customer surveys indicate that a significant number of our customers use us as their primary or sole telecommunications service provider.
Business Strategy
     We believe the following components of our business strategy provide the foundation for our continued rapid growth:
     Continue to Target Underserved Customer Segments in our Markets. We target a mass market which we believe is largely underserved by traditional wireless carriers. We believe that our rapid growth to over 3.0 million customers since our initial service launch in 2002 demonstrates the substantial demand in the United States for our innovative wireless services. We believe our rapid adoption rates and customer mix indicate that our service is expanding the overall size of the wireless market and better meeting the needs of many existing wireless users. Our average monthly usage by our customers for all markets is approximately 2,000 minutes per month, and our recent customer surveys indicate that over 80% of our customers use us as their primary phone service and that over 50% of our customers have eliminated their traditional landline phone service. Approximately 65% of our customers are first time wireless users, while the balance have switched to our service from another wireless carrier.
     Offer Affordable, Fixed Price Unlimited Service Plans With No Long-Term Service Contract Requirement. We plan to continue to offer our fixed price, unlimited wireless service plans, which we believe represent an attractive and differentiated offering to a large segment of the population. Our service is designed to provide mobile functionality while eliminating the gap between traditional wireless and wireline pricing. We believe this stimulates the demand for our wireless service, contributes to the continuing growth of our subscriber base and will increase the overall wireless adoption levels in our markets.
     Remain One of the Lowest Cost Wireless Service Providers in the United States. We believe our operating strategy, network design and high relative population density in our markets have enabled us to become, and will enable us to continue to be, one of the lowest cost providers of wireless broadband PCS services in the United States. We also believe our rapidly increasing scale will allow us to continue to drive our per-customer operating costs down in the future. In addition, we will seek to maintain operating costs per customer that are substantially below the operating costs of our national wireless broadband PCS competitors. We believe our industry leading cost position provides us and will continue to provide us with a sustainable competitive advantage.

     Expand into Attractive Markets. We have been successful in acquiring or gaining access to spectrum in a number of new metropolitan areas which share the high relative population density and customer characteristics of our Core Markets. We believe our early experience in Tampa/Sarasota, Dallas/Ft. Worth and Detroit, where, as of December 31, 2006, we have added approximately 640,000 new subscribers since the launch of service, demonstrates our ability to successfully expand our service into new metropolitan areas.
Company History
     General Wireless, Inc., or GWI, was formed in 1994 for the purpose of bidding on, acquiring and operating broadband PCS licenses as a very small business under the FCC’s designated entity rules. In 1995, GWI formed GW1, Inc. as a wholly-owned subsidiary, and shortly afterwards changed GW1, Inc.’s name to GWI PCS, Inc., or GWI PCS. In 1996, GWI PCS participated in the FCC’s C-Block auctions of broadband PCS spectrum licenses and was declared the high bidder on licenses for the Miami, Atlanta, Sacramento and San Francisco metropolitan areas. In 1999, GWI PCS changed its name to MetroPCS Wireless, Inc., or MetroPCS Wireless, and GWI changed its name to MetroPCS, Inc.
     In March 2004, MetroPCS, Inc. formed MetroPCS Communications as a wholly-owned subsidiary of MetroPCS, Inc. and in July 2004 a wholly-owned subsidiary of MetroPCS Communications, Inc., MPCS Holdco Merger Sub, Inc., merged into MetroPCS, Inc. and MetroPCS, Inc. was the surviving corporation. As a result of this merger, MetroPCS, Inc. became a wholly-owned subsidiary of MetroPCS Communications, Inc. In August 2006, MetroPCS Communications, Inc. formed MetroPCS V, Inc., as a wholly-owned subsidiary which indirectly, through a series of no longer existing wholly-owned subsidiaries, held all of the common stock of MetroPCS Wireless.
     In November 2006, as part of the restructuring associated with the issuance by MetroPCS Wireless of 9 1/4% senior notes and the senior secured credit facility, MetroPCS, Inc. was merged into MetroPCS Wireless, with MetroPCS Wireless surviving, and MetroPCS V, Inc. was renamed MetroPCS, Inc. MetroPCS Wireless’ business constitutes substantially all of the business of MetroPCS Communications, Inc. and its wholly- owned subsidiary, and parent of MetroPCS Wireless, MetroPCS, Inc. (formerly known as MetroPCS V, Inc.), and we continue to conduct business under the MetroPCS brand.
Products and Services
     Voice Services. We provide affordable, reliable, high-quality wireless broadband PCS services through the service pricing plans detailed in the chart below. All service plans are “paid-in-advance” and do not require a long-term contract. Our lowest priced $30 per month service plan allows our customers to place unlimited local calls but without the ability to add additional features. For an additional $5 to $20 per month, a subscriber may select a service plan which provides more flexibility and options such as nationwide long distance calling, unlimited text messaging (domestic and international), voicemail, caller ID, call waiting, picture and multimedia messaging, mobile Internet browsing, push e-mail, data and other a la carte options on a prepaid basis. Our most popular service plans currently are our unlimited $40 and $45 rate plans which offer unlimited local and long distance calling, text and picture messaging, enhanced voice mail, caller ID, call waiting and 3-way calling. As of December 31, 2006, over 85% of our customers had selected either our $40 or $45 service plans. On February 22, 2007 we introduced our new $50 service plan which includes unlimited mobile Internet browsing and push e-mail in addition to the services included in our $45 service plan. It is too early to judge the impact that this new service plan will have on our current service plan mix.
MetroPCS Service Plans
     Our local outbound calling areas extend in most cases beyond the boundaries of our actual license area. For example, customers in our San Francisco and Sacramento markets may place unlimited local calls while inside our service area to areas throughout the majority of northern California without incurring toll charges. Our wireline competitors generally would impose toll charges for calls within this area, while our service treats these as local calls.
     Customers who travel outside of our coverage area may roam onto other wireless networks in two ways. First, a customer may purchase service directly from a manual roaming provider in that area by providing the provider with a credit card number, which allows that provider to bill the customer directly for any roaming charges. If the customer chooses this option, we incur no costs, nor do we receive any revenues. Second, a customer may

Table of Contents

subscribe to our nationwide roaming service, branded as “TravelTalk,” under which we provide voice roaming service through agreements with other wireless carriers. We launched our TravelTalk roaming service on a prepaid basis in April 2006. Under this option, the customer makes a deposit in a prepaid account and may access our nationwide roaming service when traveling outside our local service area. We incur costs for providing, and earn revenue from, this nationwide roaming service in excess of our costs. Due to charges imposed by our roaming suppliers, our nationwide roaming service is not cost effective for customers who travel frequently outside our local service area, but the ability to roam nationwide on a prepaid basis expands the market to those customers that may find occasional roaming beneficial.
     Data Services. Our data services include:
    services provided through the Binary Runtime Environment for Wireless (“BREW”) platform, including ringtones, games and content applications;
 
    text messaging services (domestic and international), which allow the customer to send and receive alphanumeric messages that the handset can receive, store and display on demand;
 
    multimedia messaging services, which allow the customer to send and receive messages containing photographs;
 
    mobile Internet browsing; and
 
    push e-mail.
     Custom Calling Features. We offer other custom calling features, including caller ID, call waiting, three-way calling, distinctive ringtones, ring back tones and voicemail.
     Advanced Handsets. We sell a variety of handsets manufactured by nationally recognized handset manufacturers for use on our network, including models that provide color screens, camera phones and other features facilitating digital data. All of the handsets we offer are CDMA 1XRTT compliant and are capable of providing the location data mandated by the FCC’s wireless E-911 rules and regulations.
Core and Expansion Markets
     Our strategy has been to offer our services in major metropolitan markets and their surrounding areas, which we refer to as clusters. Within our Core Markets we operate three separate clusters, which include Georgia (Atlanta), South Florida (Miami) and Northern California (San Francisco and Sacramento). We initially launched our service in South Florida, Georgia and the Sacramento area of Northern California in the first quarter of 2002 and launched the San Francisco metropolitan area in September of 2002. These Core Market clusters have a licensed population of approximately 26 million of which our networks currently cover approximately 22 million. Our Core Market clusters have an average population density of 271 people per square mile, compared to the national average of 84, enjoy average annualized population growth of 1.8% compared to the national average of 1.1% and have a median household income of $53,000 compared to a national average of $47,000.
     Beginning in the second half of 2004, we began to acquire licenses opportunistically for new markets that shared characteristics similar to our existing Core Markets. In addition to these acquisitions, we also entered into agreements with Royal Street, a company in which we own a non-controlling 85% limited liability company member interest, which was granted broadband PCS licenses by the FCC in December 2005 following FCC Auction 58. For a discussion of Royal Street and Auction 58, please see “— Auction 58 and Royal Street.” We have a wholesale agreement with Royal Street that allows us to purchase up to 85% of Royal Street’s service capacity and sell it on a retail basis under the MetroPCS brand in geographic areas where Royal Street was granted FCC licenses. Our Expansion Markets include Tampa/Sarasota/Orlando, Dallas/Ft. Worth, Detroit, portions of Northern Florida, which are geographically complementary to our South Florida cluster, as well as Los Angeles, which is geographically complementary to our Northern California cluster. Within our Expansion Markets we operate or will operate four new separate clusters: Northern and Central Florida, Dallas/Ft. Worth, Detroit and Southern California. As of November 2006, we had launched our service in all of our major Expansion Markets except for Los Angeles, which we expect to launch in the second or third quarter of 2007 through our wholesale arrangement with Royal Street. Our Expansion Markets have a licensed population of approximately 40 million, of which our networks

5


Table of Contents

currently cover approximately 16 million people in the geographic areas we have launched to date, including our operations in Orlando and portions of northern Florida. Together, our Core and Expansion Markets have average population density of 339 people per square mile, compared to the national average of 84, enjoy average annualized population growth of 1.7% compared to the national average of 1.1% and have a median household income of $50,000 compared to a national average of $47,000. We believe all of these Expansion Markets are particularly attractive because of their high population densities, attractive customer demographics, high historical and projected population growth rates, favorable business climates and long commuting times relative to national averages.
     The table below provides a metropolitan area by metropolitan area overview of our Core and Expansion Markets (excluding Auction 66 Markets) including the FCC basic trading area (BTA) identification number, the number of people, or POPs, the POP density, the annualized POP growth rate, the spectrum depth and each metropolitan area’s actual or expected launch date. For our Expansion Markets we have noted whether we are the FCC license holder in each metropolitan area or if we will provide our services in that metropolitan area through our agreements with Royal Street, which holds the license. It should also be noted that all of the licensed spectrum in our Core and Expansion Markets is in the 1900 MHz PCS band and that the metropolitan area classifications in the table below conform to the FCC’s basic trading area (BTA) geographic areas for PCS spectrum.

Auction 66 Markets
     At the conclusion of FCC Auction 66 in September 2006, we were declared the high bidder on eight additional FCC licenses for total aggregate winning bids of approximately $1.4 billion, and, in November 2006, we were granted all eight of these licenses. The spectrum licenses granted as a result of Auction 66 are in the advanced wireless services, or AWS, band which includes the 1710 to 1755 MHz frequencies as well as the 2110 to 2155 MHz frequencies. These frequency ranges are near the PCS band in which we operate our Core and Expansion Markets, and we believe this spectrum to have similar technical properties to the PCS spectrum we are currently licensed to operate. We can offer the same PCS services on these AWS licenses as we offer on our other PCS spectrum and can offer additional advanced services. The AWS licenses awarded by the FCC in Auction 66 were divided into geographic areas which are different from the geographic areas associated with PCS licenses. The map below describes the geographic coverage of our Auction 66 licenses and shows the relationship between these new AWS licenses and our existing Core and Expansion Markets.

Table of Contents

(UNITED STATES MAP)
     Our Auction 66 licenses cover a total unique population of approximately 117 million. New expansion opportunities in geographic areas outside of our Core and Expansion Markets represent approximately 69 million of the total covered population of our Auction 66 Markets, as described in the chart below. Our expansion opportunities as a result of Auction 66 cover six of the top 25 metropolitan market areas in the United States, including the entire east coast corridor from Philadelphia to Boston, including New York City, as well as the entire states of New York, Connecticut and Massachusetts. Together our east coast expansion opportunities cover a geographic area of approximately 50 million people. In the Western United States our new expansion opportunities cover a geographic area of approximately 19 million people, including the San Diego, Portland, Seattle and Las Vegas metropolitan areas.
     The balance of our Auction 66 Markets, which covers a population of approximately 48 million, supplements or expands the geographic boundaries of our existing operations in Dallas/Ft. Worth, Detroit, San Francisco and Sacramento, and Royal Street’s license area in Los Angeles. Given our performance in the Core and Expansion Markets to date, we expect this additional spectrum to provide us with enhanced operating flexibility, reduced capital expenditure requirements in existing licensed areas and an expanded service area relative to our position prior to Auction 66. We intend to focus our build-out strategy in our new Auction 66 Markets initially on licenses with a total population of approximately 40 million in major metropolitan areas which we believe offer us the opportunity to achieve financial results similar to our existing Core and Expansion Markets, with a primary focus on the New York, Philadelphia, Boston and Las Vegas metropolitan areas. Of the approximately 40 million total population, we are targeting launch of operations with an initial population of approximately 30 to 32 million by late 2008 or early 2009.

     The New York EA overlaps that portion of the Northeast REA surrounding the greater New York metropolitan area. The Las Vegas EA also overlaps that portion of the West REA that also covers Las Vegas. As a result, we have 20 MHz of spectrum in these metropolitan areas which we believe will facilitate a more efficient rollout and allow us to more effectively scale our operations.
     There are incumbent governmental and non-governmental users in the AWS band. The relocation of incumbent governmental users will be funded by the proceeds of Auction 66, although certain governmental users will not be required to relocate. The non-governmental incumbent licensees will need to be relocated pursuant to the FCC’s approved spectrum relocation order, which may require us to pay for their relocation expenses which we currently estimate to be approximately $40 to $60 million, and which requires voluntary negotiation for the first three years before the commercial incumbents are subject to mandatory relocation.
Auction 58 and Royal Street
     In January 2005, the FCC conducted Auction 58 for wireless broadband PCS spectrum. Auction 58 was the first significant FCC auction for wireless broadband PCS spectrum since Auction 35 in 2001. Auction 58, like other major auctions conducted by the FCC, was designed to allow small businesses, very small businesses and other so called designated entities, or DEs, to acquire spectrum and construct wireless networks to promote competition with existing carriers. To that end, the FCC designated certain blocks of wireless broadband PCS spectrum for which only DEs could apply. Qualified DEs were able to bid on these restricted or “closed” licenses which were not available to other bidders who did not qualify as DEs. In addition, very small business DEs were permitted to apply for and bid on “open” licenses with a bidding credit of 25% of the gross bid price. We entered into a cooperative arrangement with an unaffiliated very small business entrepreneur and invested in Royal Street, a DE that qualified to bid on “closed” licenses and was eligible for the 25% bidding credit on “open” licenses. We own a non-controlling 85% limited liability company member interest in Royal Street Communications and may elect only two of the five members to Royal Street Communication’s management committee, which has the full power to direct the management of Royal Street. C9 Wireless, LLC, or C9, has control over the operations of Royal Street because it has the right to elect three of the five members of Royal Street Communication’s management committee. C9 has the right to put all or part of its ownership interest in Royal Street Communications to us, but due to regulatory restrictions, we have no corresponding right to call C9’s ownership interest in Royal Street Communications. The put right has been structured so that its exercise will not adversely affect Royal Street’s continued eligibility as a very small business designated entity during periods where such eligibility is required. If C9 exercises its put right, we will be required to pay a fixed return on C9’s invested capital in Royal Street Communications, which fixed return diminishes annually beginning in the sixth year following the grant of Royal Street’s FCC licenses. These put rights expire in June 2012.
     Auction 58 was completed in February 2005, and Royal Street Communications made its final payment to the FCC for the licenses it won in Auction 58 in March 2005. In December 2005, Royal Street Communications was granted the following licenses on which it was the high bidder at the conclusion of Auction 58: Los Angeles, California; and Orlando, Jacksonville, Lakeland-Winter Haven, Melbourne-Titusville and Gainesville, Florida basic trading areas.
     Royal Street holds all of the Auction 58 licenses through its wholly-owned subsidiaries and has entered into certain cooperative agreements with us relating to the financing, design, construction and operation of the networks. The Royal Street agreements are based on a “wholesale model” in which Royal Street plans to sell up to 85% of its engineered service capacity on a wholesale basis to us, which we in turn will market on a retail basis under the MetroPCS-brand to our customers within the covered area. In addition, the Royal Street agreements contemplate that MetroPCS, at Royal Street’s request and at all times subject to Royal Street’s direction and control, will build-out the networks, provide information to Royal Street relating to the budgets and business plans as well as arrange for administrative, clerical, accounting, credit, collection, operational, engineering, maintenance, repair, and technical services. We do not own or control the Royal Street licenses. However, pursuant to contractual arrangements with Royal Street, we have access, via the wholesale arrangement, to as much as 85% of the engineered service capacity of Royal Street’s network with the remaining 15% reserved by Royal Street to sell to other parties.
     Also, pursuant to another of the Royal Street agreements, upon Royal Street’s request, we will provide financing for the acquisition and build-out of licenses won in Auction 58. As of

Table of Contents

December 31, 2006 the maximum amount that Royal Street may borrow from us under the loan agreement is approximately $500 million. As of December 31, 2006 Royal Street has borrowed $394 million from us under the loan agreement, approximately $294 million of which was used for the acquisition of new licenses. In March 2007, Royal Street borrowed an additional $70 million from us under the loan agreement. Interest accrues under the loan agreement at a rate equal to 11% per annum, compounded quarterly. Royal Street has commenced repayment of that portion of the loans related to the Orlando and Lakeland-Winter Haven markets. The proceeds from this loan are to be used by Royal Street to make payments for the licenses won in Auction 58, to finance the build-out and operation of the Royal Street network infrastructure, and to make payments under the loan until Royal Street has positive free cash flow.
License Term
     All of the broadband PCS licenses held by us and by Royal Street have an initial term of ten years after the initial grant date (which varies by license, but the initial San Francisco, Sacramento, Miami and Atlanta licenses were granted in January 1997), and, subject to applicable conditions, may be renewed at the end of their terms. The AWS licenses granted in Auction 66 have an initial term of fifteen years after the initial grant of the license. Each FCC license is essential to our and Royal Street’s ability to operate and conduct our and Royal Street’s business in the area covered by that license. We continue to file renewal applications for our broadband PCS licenses as the windows to file renewal applications open. One application has been granted and one application is currently pending for those licenses that expire in April 2007 and the FCC has granted all of the renewal applications for those licenses that expired in January 2007. For a discussion of general licensing requirements, please see “— General Licensing Requirements and Broadband Spectrum Allocations.”
Distribution and Marketing
     We offer our products and services under the “MetroPCS” brand indirectly through approximately 2,000 independent retail outlets and directly to our customers through 95 Company-operated retail stores. Our indirect distribution outlets include a range of local, regional and national mass market retailers and specialty stores. A significant portion of our gross customer additions have been added through our indirect distribution outlets and for the twelve months ended December 31, 2006, 84% of our gross customer additions were through indirect channels. We have over 2,000 locations where customers can make their monthly payments, and many of these locations also serve as distribution points for our products and services. Our cost to distribute through direct and indirect channels is substantially similar, and we believe our mix of indirect and direct distribution allows us to reach the largest number of potential customers in our markets at a low relative cost. We plan to increase our number of indirect distribution outlets and Company-operated stores in both Core and Expansion Markets and in new markets acquired in the future, such as the Auction 66 Markets.
     We advertise locally to develop our brand and support our indirect and direct distribution channels. We advertise primarily through local radio, cable, television, outdoor and local print media. In addition, we believe we have benefited from a significant number of word-of-mouth customer referrals.
Customer Care, Billing and Support Systems
     We use several outsourcing solutions to efficiently deliver quality service and support to our customers as part of our strategy of establishing and maintaining our leadership position as a low cost telecommunications provider while ensuring high customer satisfaction levels. We outsource some or all of the following back office and support functions to nationally recognized third-party providers:
    Customer Care. We have outsourcing contracts with two nationally recognized call center vendors. These call centers are staffed with professional and bilingual customer service personnel, who are available to assist our customers 24 hours a day, 365 days a year. We also provide automated voice response services to assist our customers with routine information requests. We believe providing quality customer service is an important element in overall customer satisfaction and retention, and we regularly review performance of our call center vendors.
 
    Billing. We utilize a nationally recognized third-party billing platform that bills, monitors and analyzes payments from our customers. We offer our customers the option of receiving web-based and short messaging service-based bills as well as traditional paper bills. We also offer our customers the option of automatic payment of their bills via credit or debit cards. Very few of our

      customers utilize paper bills and substantially all of our customers receive their bills through the short message service included with our wireless service.
 
    Payment Processing. Customers may pay their bills by credit card, debit card, check or cash. We have over 2,000 locations where customers choosing to pay for their monthly service in cash can make their payments. Many of these locations also serve as distribution points for our products and services making them convenient for customer payments. Customers may also make payments at any of the Western Union locations throughout our metropolitan service areas.
 
    Logistics. We outsource logistics associated with shipping handsets and accessories to our distribution channels to a nationally recognized logistics provider.
Network Operations
     We believe we were the first U.S. wireless broadband PCS carrier to have 100% of our customers on a CDMA 1XRTT network. We began building our network in 2001, shortly after other CDMA carriers began upgrading their networks to 1XRTT. As a result, we believe we deployed our network with third generation capabilities at a much lower cost than incurred by other carriers who were forced to undergo a technology migration to deploy second generation CDMA networks. Since all of our handsets are CDMA 1XRTT compliant, we receive the full capacity and quality benefits provided by CDMA 1XRTT across our entire network and customer base.
     As of December 31, 2006, our network consists of 11 switches at eight switching centers and 3,397 operating cell sites. A switching center serves several purposes, including routing calls, managing call handoffs, managing access to the public telephone network and providing access to voicemail and other value-added services. Currently, almost all of our cell sites are co-located, meaning our equipment is located on leased facilities that are owned by third parties retaining the right to lease the facilities to additional carriers. Our switching centers and national operations center provide around-the-clock monitoring of our network base stations and switches.
     Our switches connect to the public telephone network through fiber rings leased from third-parties, which facilitate the first leg of originating and terminating traffic between our equipment and local exchange and long distance carriers. We have negotiated interconnection agreements with relevant local exchange carriers in our service areas.
     We use third-party providers for long distance services and the majority of the backhaul services. Backhaul services are the telecommunications services that we use to carry traffic to and from our cell sites and our switching facilities.
Network Technology
     Wireless digital signal transmission is accomplished by using various forms of frequency management technology, or “air interface protocols.” The FCC has not mandated a universal air interface protocol for wireless broadband PCS systems; rather, wireless broadband PCS systems in the United States operate under one of three dominant principle air interface protocols: CDMA; time division multiple access, or TDMA; or global system for mobile communications, or GSM. All three air interface protocols are incompatible with each other. Accordingly, a customer of a system that utilizes CDMA technology is unable to use a CDMA handset when traveling in an area not served by a CDMA-based wireless carrier, unless the customer carries a dual-band/dual-mode handset that permits the customer to use the alternate wireless system in that area. In addition, certain carriers also restrict customers from changing the programming of their phones to be used on other carriers’ networks using the same air interface protocol.
     We believe 10 MHz of spectrum to be sufficient to begin service in metropolitan areas using technology that divides the base station coverage area served by a transmitter receiver into three parts or “sectors” (segments of the circle representing the base station’s broadcast area). However, in metropolitan areas with only 10 MHz of spectrum we have a network design capable of subdividing the service area into six parts or sectors and to deploy these six-sector cells in selected, high-demand areas. This will increase the capacity of the wireless base stations in these markets by doubling the number of sectors over which a base station’s antennas can handle calls simultaneously. Our vendors have informed us that cell sites using six sectors have been in operation for many years in the U.S., and we have obtained actual performance data on cell sites that have been operational for multiple years.

11


Table of Contents

We and Royal Street have commercially deployed six-sector cell sites in certain geographic areas in 2006, and we anticipate that Royal Street will deploy this technology in Los Angeles in 2007.
     We believe that CDMA technology uses spectrum more efficiently than any alternative commonly used wireless technology in 10 MHz. We also intend to buy EVRC-B, or 4G vocoder, handsets when available. 4G vocoder handsets allow for greater capacity in the network. We believe these handsets will be available in 2007. We currently intend to further enhance network capacity by upgrading our networks with EV-DO Revision A with Voice-Over-Internet-Protocol, or VoIP, which we anticipate will be available in 2008. When combined with six-sector technology, it is our expectation that new 4G vocoder and EV-DO Revision A with VoIP will more than double the effective available spectrum relative to three-sector, 1XRTT technology. Thus, we believe 10 MHz of spectrum has the effective capacity of 20 MHz using today’s technologies. We anticipate that spectral efficiency will continue to improve over the next several years, allowing us to keep up with the increased usage of third-generation services.
     As a result of Auction 66, we were granted licenses for additional spectrum in some of these metropolitan areas. We acquired this spectrum because the price of the spectrum was attractive when considering the additional cost that would have been incurred to employ the technologies described above to more fully utilize the existing 10 MHz. In many cases, our Auction 66 spectrum will allow us to enlarge our existing geographic service area, which we believe will further enhance the attractiveness of our services.
     Our decision to use CDMA is based on several key advantages over other digital protocols, including the following:
     Higher network capacity. Cellular technology capitalizes on reusing discrete amounts of spectrum at a cell site that can be used at another cell site in the system. We believe, based on studies by CDMA handset manufacturers, that our implementation of CDMA digital technology will eventually provide approximately seven to ten times the system capacity of analog technology and approximately three times the system capacity of TDMA and GSM systems, resulting in significant operating and cost efficiencies. Additionally, we believe that CDMA technology provides network capacity and call quality that is superior to other wireless technologies.
     Longer handset battery life. While a digital handset using any of the three digital air interface protocols has a substantially longer battery life than an analog cellular handset, CDMA handsets can provide even longer periods between battery recharges than other commonly deployed digital PCS technologies.
     Fewer dropped calls. CDMA systems transfer calls throughout the CDMA network using a “soft hand-off,” which connects a mobile customer’s call with a new base station while maintaining a connection with the base station currently in use, and “hard hand-off,” which disconnects the call from the current base station when it connects to another base station. CDMA networks monitor the quality of the transmission received by multiple neighbor base stations simultaneously to select the best transmission path and to ensure that the call is not disconnected in one base station unless replaced by a stronger signal from another. Analog, TDMA and GSM networks only use a hard hand-off and disconnect the call from the current base station as it connects with a new one without any simultaneous connection to both base stations. Since CDMA allows for both hard and soft hand-off, it results in fewer dropped calls compared to other wireless technologies.
     Simplified frequency planning. TDMA and GSM service providers spend considerable time and money on frequency planning because they must reuse frequencies to maximize network capacity. CDMA technology allows reuse of the same subset of allocated frequencies in every cell, substantially reducing the need for costly frequency planning.
     Efficient migration path. CDMA 1XRTT technology can be upgraded easily and cost-effectively for enhanced voice and data capabilities. The technology requires relatively low incremental investment for each step along the migration path with relatively modest incremental capital investment levels as demand for more robust data services or additional capacity develops.
     Privacy and security. CDMA uses technology that requires accurate time and code phase knowledge to decode, increasing privacy and security.

Competition
     We compete directly in each of our metropolitan areas with other wireless service providers, with wireline companies and increasingly with cable companies by providing a wireless alternative to traditional wireline service. The wireless industry is dominated by national carriers, such as Cingular Wireless, Verizon Wireless, Sprint Nextel and T-Mobile and their prepaid affiliates or brands, which have an estimated 84% of the national wireless market share as measured by number of subscribers, according to the Federal Communications Commission’s Annual Report and Analysis of Competitive Market Conditions with Respect to Commercial Mobile Services, FCC 06-142, released September 29, 2006. National carriers typically offer post-paid plans that require long-term contracts and credit checks or deposits. Over the past few years, the wireless industry has seen an emergence of several new competitors that provide either pay-as-you-go or prepaid wireless services. Some of these competitors, such as Virgin Mobile USA, Amp’d Mobile and Tracfone, are non-facility based mobile virtual network operators, or MVNOs, that contract with wireless network operators to provide a separately branded wireless service. These MVNOs typically also charge by the minute rather than offering flat-rate unlimited service plans. In addition, several large satellite companies, computer companies and Internet search and portal companies have indicated an interest in establishing next generation wireless networks and VoIP providers have indicated that they may offer wireless services over a Wi-Fi/Cellular network to compete directly with us. Some companies, such as Leap Wireless d/b/a Cricket and Sure West Wireless, are regional carriers with unlimited fixed-rate service plans similar to ours. Thus, we compete with both the national carriers, the prepaid, pay-as-you-go service providers and in some cases regional and local carriers, and may face additional competition from new entrants with substantial resources in the future. We believe that competition for subscribers among wireless communications providers is based mostly on price, service area, services and features, call quality and customer service. The wireline industry is also dominated by large incumbent carriers, such as AT&T, Verizon, and BellSouth, and competitive local exchange or Voice-Over-Internet-Protocol, or VoIP, service providers, such as Vonage, McLeod USA, and XO Communications. The cable industry is also dominated by large carriers such as Time Warner Cable, Comcast and Cox Communications. These cable companies formed a joint venture along with Sprint Nextel and Bright House Networks called SpectrumCo LLC, or SpectrumCo, which bid on and acquired 20 MHz of AWS spectrum in a number of major metropolitan areas throughout the United States, including all of the major metropolitan areas which comprise our Core, Expansion and Auction 66 Markets.
     Sprint Nextel recently announced that it will offer an unlimited local calling plan under its Boost brand in certain of the geographic areas in which we offer service. In response, in certain of our markets we have added additional features to our existing service plans. Currently, in our San Francisco, Sacramento, and Dallas/Ft. Worth metropolitan areas we have added to the $35 service plan unlimited long distance in the continental United States, to the $40 service plan unlimited short message and multimedia message services, and to the $45 service plan unlimited mobile Internet browsing and international short message service. As competition develops, we may offer similar service plans in our other metropolitan areas, we may add additional features or services to our existing service plans, or make other changes to our service plans.
     Many of our wireless, wireline and cable competitors’ resources are substantially greater, and their market shares are larger, than ours, which may affect our ability to compete successfully. Additionally, many of our wireless competitors offer larger coverage areas or nationwide calling plans that do not give rise to additional roaming charges, and the competitive pressures of the wireless communications industry have led them to offer service plans with growing bundles of minutes of use at lower per minute prices or price plans with unlimited nights and weekends. Our competitors’ plans could adversely affect our ability to maintain our pricing, market penetration, growth and customer retention. In addition, large national wireless carriers have been reluctant to enter into roaming agreements at attractive rates with smaller and regional carriers like us, which limits our ability to serve certain market segments. Moreover, the FCC is pursuing policies making additional spectrum for wireless services available in each of our markets, which may increase the number of our wireless competitors and enhance our wireless competitors’ ability to offer additional plans and services. Further, since many of our competitors are large companies, they can require handset manufacturers to provide the newest handsets exclusively to them. Our competitors also can afford to heavily subsidize the price of the subscriber’s handset because they require long term contracts. These advantages may detract from our ability to attract customers from certain market segments.
     We also compete with companies using other communications technologies, including paging, digital two-way paging, enhanced specialized mobile radio, domestic and global mobile satellite service, and wireline telecommunications services. We also may face competition from providers of an emerging technology known as Worldwide Interoperability for Microwave Access, or WiMax, which is capable of supporting wireless

transmissions suitable for mobility applications. Also, certain mobile satellite providers recently have received authority to offer ancillary terrestrial service and a coalition of companies which includes DIRECTV Group, EchoStar, Google, Inc., Intel Corp. and Yahoo! has indicated its desire to establish next generation wireless networks and technologies in the 700 MHz band. These technologies may have advantages over our technology that customers may ultimately find more attractive. Additionally, we may compete in the future with companies that offer new technologies and market other services we do not offer or may not be available with our network technology, from our vendors or within our spectrum. Some of our competitors do or may bundle these other services together with their wireless communications service, which customers may find more attractive. Energy companies, utility companies, satellite companies and cable operators also are expanding their services to offer telecommunications services.
     In the future, we may also face competition from mobile satellite service, or MSS, providers, as well as from resellers of these services. The FCC has granted to some MSS providers, and may grant others, the flexibility to deploy an ancillary terrestrial component to their satellite services. This added flexibility may enhance MSS providers’ ability to offer more competitive mobile services. In addition, we also may face competition from providers of WiMax, which is capable of supporting wireless transmissions suitable for mobility applications, using exclusively licensed or unlicensed spectrum.
Seasonality
     Net customer additions are typically strongest in the first and fourth calendar quarters of the year. Softening of sales and increased churn in the second and third calendar quarters of the year usually combine to result in fewer net customer additions during the second and third calendar quarters. The following table sets forth our net subscriber additions and total subscribers from the first quarter of 2004 through the fourth quarter of 2006.

Inflation
     We do not believe that inflation has had a material effect on our operations.
Employees
     As of December 31, 2006, we had 2,046 employees. We believe our relationship with our employees is good. None of our employees is covered by a collective bargaining agreement or represented by an employee union.
Regulation
     The government regulates the wireless telecommunications industry extensively at both the federal level and, to varying degrees, at the state and local levels. Administrative rulemakings, legislation and judicial proceedings can affect this government regulation and may be significant to us. In recent years, the regulation of the communications industry has been in a state of flux as Congress, the FCC, state legislatures and state regulators have passed laws and promulgated policies to foster greater competition in telecommunications markets.

Federal Regulation
     Wireless telecommunications systems and services are subject to extensive federal regulation under the Communications Act of 1934, as amended, or the Communications Act, and the implementing regulations adopted thereunder by the FCC. These regulations and associated policies govern, among other things, applications for and renewals of licenses to construct and operate wireless communications systems, ownership of wireless licenses and the transfer of control or assignment of such licenses, the ongoing technical, operational and service requirements under which wireless licensees must operate, the rates, terms and conditions of service, the protection and use of customer information, roaming policies, the provision of certain services, such as E-911, and the interconnection of communications networks.
General Licensing Requirements and Broadband Spectrum Allocations
     The FCC awards certain broadband PCS licenses for geographic service areas called Major Trading Areas, or MTAs, and other broadband PCS licenses for Basic Trading Areas, or BTAs, defined by Rand McNally & Company. Under the broadband PCS licensing plan, the United States and its possessions and territories are divided into 493 BTAs, all of which are included within 51 MTAs. The FCC allocates 120 MHz of radio spectrum in the 1.9 GHz band for licensed broadband PCS. The FCC divided the 120 MHz of spectrum into two 30 MHz blocks, known as the A- and B-Blocks, licensed for each of the 51 MTAs, one 30 MHz block, known as the C-Block, licensed for each of the 493 BTAs, and three 10 MHz blocks, known as the D-, E- and F-Blocks, licensed for each of the 493 BTAs, for a total of more than 2,000 licenses. Each broadband PCS license authorizes operation on one of six frequency blocks allocated for broadband PCS. However, licensees are given the flexibility to partition their service areas and to disaggregate their spectrum into smaller areas or spectrum blocks with the approval of the FCC. The FCC also awarded two cellular licenses on a metropolitan statistical area, or MSA, and rural service area, or RSA, basis with 25 MHz of spectrum for each license. There are 306 MSAs and 428 RSAs in the United States. Licensees of cellular spectrum can offer PCS services in competition with broadband PCS licensees. Many of our competitors utilize a combination of cellular and broadband PCS spectrum to provide their services.
     In 2005, the FCC allocated an additional 90 MHz of spectrum to be used for AWS. Each AWS license authorizes operation on one of six frequency blocks. The FCC divided the 90 MHz of spectrum into two 10 MHz and one 20 MHz blocks licensed for each of 12 designated regional economic area groupings, or REAG, one 10 MHz and one 20 MHz block licensed for each of 176 designated economic areas, or EA, licenses, and a 20 MHz block licensed for each of 734 designated metropolitan statistical area/rural service area basis. The economic areas are geographic areas defined by the Regional Economic Analysis Division of the Bureau of Economic Analysis, U.S. Department of Commerce. Regional economic areas are collections of economic areas. Metropolitan statistical areas and rural service areas are defined by the Office of Management and Budget and the FCC, respectively. Licensees of AWS spectrum can offer PCS and cellular services in competition with broadband PCS and cellular licensees. The FCC auctioned the AWS spectrum in a single multiple round auction which commenced on August 9, 2006. In November 2006, the FCC granted us 10 MHz REAG licenses in the Northeast and West, and 10 MHz EA licenses in New York, Detroit-Ann Arbor, Dallas/Ft. Worth, Las Vegas, Grand Rapids-Muskegon-Holland, Michigan, and Shreveport-Bossier City, Louisiana. See “Business— Ownership Restrictions.”
     The FCC sets construction benchmarks for broadband PCS and AWS licenses. All broadband PCS licensees, holding licenses originally granted as 30 MHz licenses, must construct facilities to provide service covering one-third of their service area’s population within five years, and two-thirds of the population within ten years, of their initial license grant date. All broadband PCS licensees holding licenses which originally were granted as, or disaggregated to become, 10 MHz and 15 MHz licenses must construct facilities to provide service to 25% of the license area within five years of their initial license grant date, or make a showing of substantial service. While the FCC has granted limited extensions to and waivers of these requirements, licensees failing to meet these coverage requirements generally must forfeit their license. Either we or the previous licensee for each of our broadband PCS licenses has satisfied the applicable five-year coverage requirement for our licenses and the ten-year requirement for those licenses with license terms expiring in January 2007. All AWS licensees will be required to construct facilities to provide substantial service by the end of the initial 15-year license term.
     The FCC generally grants broadband PCS licenses for ten-year terms that are renewable upon application to the FCC. AWS licenses are granted for an initial 15-year term and then are renewable for successive ten-year terms. Our initial PCS license terms ended in January 2007 and we have filed renewal applications for additional ten-year terms. All of these applications for our initial PCS licenses have been granted. We also are filing renewal

15


Table of Contents

applications for our other PCS licenses as the filing windows open and in some instances our applications already have been granted while others are still pending or waiting for the filing window to open. Our initial AWS license terms end in November 2021. The FCC may deny our broadband PCS and AWS license renewal applications for cause after appropriate notice and hearing. The FCC will award a renewal expectancy to us for our broadband PCS licenses if we meet specific past performance standards. To receive a renewal expectancy for our broadband PCS licenses, we must show that we have provided substantial service during our past license term, and have substantially complied with applicable FCC rules and policies and the Communications Act. The FCC defines substantial service as service which is sound, favorable and substantially above a mediocre service level only minimally warranting renewal. If we receive a renewal expectancy, it is very likely that the FCC will renew our existing broadband PCS licenses. If we do not receive a renewal expectancy, the FCC may accept competing applications for the license renewal period, subject to a comparative hearing, and may award the broadband PCS license for the next term to another entity. We believe we will be eligible for a renewal expectancy for our broadband PCS licenses that will be renewed in the near term, but cannot be certain because the applicable FCC standards are not precisely defined.
     The FCC may deny applications for FCC licenses, and in extreme cases revoke FCC licenses, if it finds a licensee lacks the requisite qualifications to be a licensee. In making this determination, the FCC considers any adverse findings against the licensee or applicant in a judicial or administrative proceeding involving felonies, possession or sale of illegal drugs, fraud, antitrust violations or unfair competition, employment discrimination, misrepresentations to the FCC or other government agencies, or serious violations of the Communications Act or FCC regulations. We believe there are no activities and no judicial or administrative proceedings involving us that would warrant such a finding by the FCC.
     The FCC also has other broadband wireless spectrum allocation proceedings in process. In 2004, the FCC sought comment on service rules for an additional 20 MHz of AWS spectrum in the 1915-1920 MHz, 1995-2000 MHz, 2020-2025 MHz and 2175-2180 MHz bands and has indicated that it intends to initiate a further proceeding with regard to an additional 20 MHz of AWS spectrum in the 2155-2175 MHz band in the future. These proposed allocations present certain unique spectrum clearing and interference issues, and we cannot predict with any certainty the likely timing of these proposed allocations. A company has also filed an application for 20 MHz of this spectrum to be licensed on an exclusive basis without an auction, which the FCC put on public notice on March 9, 2007. The FCC also has allocated an additional 60 MHz of wireless broadband spectrum in the 700 MHz band and the FCC is now required by statute to commence auctioning this spectrum no later than January of 2008. On August 10, 2006, the FCC issued a Notice of Proposed Rulemaking seeking comment on possible changes to the 700 MHz band plan, including possible changes in the service area sizes for the 60 MHz of as yet unauctioned 700 MHz spectrum. We are participating in this proceeding and advocating a greater number of smaller license areas, but cannot predict the likely outcome or whether it will benefit or adversely affect us. On September 8, 2006, the FCC also sought comment on the existing licenses in the 700 MHz spectrum and the disposition of the 700 MHz spectrum returned by Nextel Communications. Furthermore, in December 2006, the FCC sought comment on the possible implementation of a nationwide broadband interoperable network in the 700 MHz band allocated for public safety use, which also could be used by commercial service providers on a secondary basis.
Transfer and Assignment of PCS Licenses
     The Communications Act requires prior FCC approval for assignments or transfers of control of any license or construction permit, with limited exceptions. The FCC may prohibit or impose conditions on assignments and transfers of control of licenses. We have managed to secure the requisite approval of the FCC to a variety of assignment and transfer proposals without undue delay. Although we cannot assure you that the FCC will approve or act in a timely fashion on any of our future requests to approve assignment or transfer of control applications, we have no reason to believe the FCC will not approve or grant such requests or applications in due course. Because an FCC license is necessary to lawfully provide wireless broadband service, FCC disapproval of any such request would adversely affect our business plans.
     The FCC allows FCC licenses and service areas to be subdivided geographically or by bandwidth, with each divided license covering a smaller service area and/or less spectrum. Any such division is subject to FCC approval, which cannot be guaranteed. In addition, in May 2003, the FCC adopted a Report and Order to facilitate development of a secondary market for unused or underused wireless spectrum by imposing less restrictive standards on transferring and leasing of spectrum to third parties. These policies provide us with alternative means to obtain additional spectrum or dispose of excess spectrum, subject to FCC approval and applicable FCC

conditions. These alternatives also allow our competitors to obtain additional spectrum or new competitors to enter our markets.
Ownership Restrictions
     Before January 1, 2003, the FCC rules imposed a “spectrum cap” limiting to 55 MHz the amount of commercial mobile radio service, or CMRS, spectrum an entity could hold in a major market. The FCC now has eliminated the spectrum cap for CMRS in favor of a case-by-case review of transactions raising CMRS spectrum concentration issues. Previously decided cases under the case-by-case approach indicate that the FCC will screen a transaction for competitive concerns if 70 MHz of cellular and broadband PCS spectrum in a single market is attributable to a party or affiliated group, or if there is a material change in the post-transaction market share concentrations as measured by the Herfindahl-Hirschman Index. The 70 MHz benchmark may change over time as more and more broadband spectrum is made available, and its applicability to AWS or 700 MHz spectrum is unclear. By eliminating a spectrum cap for CMRS in favor of a more flexible analysis, we believe the FCC’s changes will increase wireless operators’ ability to attract capital and make investments in other wireless operators. We also believe that these changes allow our competitors to make additional acquisitions of spectrum and further consolidate the industry.
     The FCC rules initially established specific ownership requirements for broadband PCS licenses obtained in the C- and F-Block auctions, which are known as the entrepreneur’s block auctions. We were subject to these requirements until recently because our licenses were obtained in the C-Block auction. When we acquired our C-Block broadband PCS licenses, the FCC’s rules for the C-Block auction permitted entities to exclude the gross revenues and assets of non-attributable investors in determining eligibility as a DE and small business, so long as the licensee employed one of two control group structural options. We elected to meet the 25% control group option which required that, during the first ten years of the initial license term (which for us would have ended on January 27, 2007), a licensee have an established group of investors meeting the requirements for the C-Block auctions, holding at least 50.1% of the voting interests of the licensee, possessing actual and legal control of both the control group and the licensee, and electing or appointing a majority of the licensee’s board of directors. In addition, those qualifying investors were required to hold no less than a specified percentage of the equity. After the first three years of the license term (which for us ended January 27, 2000), the qualifying investors must collectively retain at least 10% of the licensee’s equity interests. The 10% equity interest could be held in the form of options, provided the options were exercisable at any time, solely at the holder’s discretion, at an exercise price less than or equal to the current market value of the underlying shares on the short-form auction application filing date or, for options issued later, the options’ issue date. Finally, under the 25% control group option, no investor or group of affiliated investors in the control group was permitted to hold over 25% of the licensee’s overall equity during the initial license term.
     In August 2000, the FCC revised its control group requirements as they applied to DE licensees. The revised rules apply a control test that obligates the eligible very small business members of a DE licensee to maintain de facto (actual) and de jure (legal) control of the business. Because we had taken advantage of installment payments at the time we purchased the licenses in the C-Block auction, we were still required to comply with the control group requirements. In May 2005, we paid off the remaining installments we owed to the FCC on all of the licenses we acquired in the C-Block auction. In addition, none of the license acquisitions made by us after the C-Block auction required that we qualify as a DE. As a consequence, upon repayment of the installments to the FCC, we were no longer subject to the FCC rules and regulations pertaining to unjust enrichment or installment financing. Based on this change of circumstances, we were no longer required to maintain our previous status as an eligible DE or to abide by the ownership restrictions applicable to DEs under the 25% control group option. In August 2005, we filed administrative updates with the FCC with respect to all of our FCC licenses, which served to notify the FCC and all interested parties of this change of circumstances. Effective as of December 31, 2005, MetroPCS Communications, Inc.’s Class A Common Stock was converted into our common stock and the built-in control structures required to maintain our DE status were terminated with the consent of the FCC.
     Royal Street is a DE which must meet and continue to abide by the FCC’s DE requirements, including the revised control group requirements. The FCC rules provide that if a license is transferred to a non-eligible entity, an entity which qualifies for a lesser credit on open licenses, or the DE ceases to be qualified, the licensee may lose all closed licenses which are not constructed, and may be required to refund to the FCC a portion of the bidding credit received for all open licenses, based on a five-year straight-line basis and might lose its closed licenses or be required to pay an unjust enrichment payment on the closed licenses. In Auction 58, Royal Street received a bidding credit equal to approximately $94 million. If Royal Street were found to no longer qualify as a DE, it would be

17


Table of Contents

required to repay the FCC the amount of the bidding credit on a five-year straight-line basis. Any closed licenses which are transferred prior to the five-year anniversary may also be subject to an unjust enrichment payment. Royal Street also is party to certain grandfathered arrangements with us that cannot be extended to new or additional licenses due to recent changes in the DE rules. For this reason, the ability of Royal Street to own or control additional licenses in the future will be inhibited absent significant changes in the business relationship with us.
     Specifically, in April 2006, the FCC adopted a Second Report and Order and Second Further Notice of Proposed Rulemaking relating to its DE program. This Order was clarified by the FCC in its June 2006 Order on Reconsideration of the Second Report and Order, which largely upheld the rules established in the Second Report and Order but clarified that the FCC’s revised unjust enrichment rules would only apply to licenses initially granted after April 25, 2006 (the Second Report and Order, as clarified by the Order on Reconsideration, is referred to herein as the DE Order). First, the FCC found that an entity that enters into an impermissible material relationship will be ineligible for award of designed entity benefits and subject to unjust enrichment on a license-by-license basis. The FCC concluded that any arrangement whereby a DE leases or resells more than fifty percent of the capacity of its spectrum or network to third parties is an impermissible material relationship and will render the licensee ineligible for any DE benefits, including bidding credits, installment payments, and, as applicable, set-asides, and will subject the DE to unjust enrichment payments on a license-by-license basis. Second, the FCC found that any entity which has a spectrum leasing or resale arrangement (including wholesale arrangements) with an applicant for more than 25% of the applicant’s total spectrum capacity on a license-by-license basis will be considered to have an attributable interest in the applicant. Based on these revised rules, Royal Street will not be able to enter into the same relationship it currently has with us for any future FCC auctions and receive DE benefits, including bidding credits. In addition, Royal Street will not be able to acquire any additional DE licenses in the future, and resell services to us on those licenses on the same basis as the existing arrangements, without making itself ineligible for DE benefits. The FCC, however, grandfathered otherwise impermissible material relationships for existing licenses that were entered into or filed with the FCC before the release date of the FCC order.
     Third, the FCC has revised the DE unjust enrichment rules to provide that a licensee which seeks to assign or transfer control of the license, enter into an otherwise impermissible material relationship, or otherwise loses its eligibility for a bidding credit for any reason, will be required to reimburse the FCC for any bidding credits received as follows: if the DE loses its eligibility or seeks to assign or transfer control of the license, the DE will have to reimburse the FCC for 100% of the bidding credit plus interest if such loss, assignment or transfer occurs within the first five years of the license term; 75% if during the sixth and seventh year of the license term; 50% if during the eighth and ninth of the license term; and 25% in the tenth year. In addition, to the extent that a DE enters into an impermissible material relationship, seeks to assign or transfer control of the license, or otherwise loses its eligibility for a bidding credit for any reason prior to the filing of the notification informing the FCC that the construction requirements applicable at the end of the license term have been met, the DE must reimburse the FCC for 100% of the bidding credit plus interest. In its June 2006 Order on Reconsideration of the Second Report and Order, the FCC clarified its rules to state that its changes to the DE unjust enrichment rules would only apply to licenses initially issued after April 25, 2006. Licenses issued prior to April 25, 2006, including those granted to Royal Street from Auction 58, would be subject to the five-year unjust enrichment rules previously in effect. Likewise, the requirement that the FCC be reimbursed for the entire bidding credit amount owed if a DE loses its eligibility for a bidding credit prior to the filing of the notifications informing the FCC that the construction requirements applicable at the end of the license term have been met applies only to those licenses that are initially granted on or after April 25, 2006. Fourth, the FCC has adopted rules requiring a DE to seek approval for any event in which it is involved that might affect its ongoing eligibility, such as entry into an impermissible material relationship, even if the event would not have triggered a reporting requirement under the FCC’s existing rules. In connection with this rule change, the FCC now requires DEs to file annual reports with the FCC listing and summarizing all agreements and arrangements that relate to eligibility for designated entity benefits. Fifth, the FCC indicated that it will step up its audit program of DEs and has stated that it will audit the eligibility of every DE that wins a license in the AWS auction at least once during the initial license term. Sixth, these changes will all be effective with respect to all applications filed with the FCC that occur after the effective date of the FCC’s revised rules, including the AWS auction.
     Several interested parties filed a Petition for Expedited Reconsideration and a Motion for Expedited Stay Pending Reconsideration or Judicial Review of the DE Order. The Petitions challenged the DE Order on both substantive and procedural grounds. Among other claims, the Petitions contested the FCC’s effort to apply the revised rules to applications for the AWS auction and to apply the revised unjust enrichment payment schedule to existing DE arrangements. In the Motion for Stay, the petitioners requested that the FCC also stay the effectiveness of the rule changes, and stay the commencement of the AWS auction which commenced on June 29, 2006 and all

18


Table of Contents

associated pre-AWS auction deadlines. The FCC did not grant the stay, and the petitioners sought a court stay. On June 7, 2006, the petitioners filed an appeal of the DE Order with the Court of Appeals for the Third Circuit and sought an emergency stay of the DE Order. On June 29, 2006, the Court issued a decision denying the emergency stay motion. The parties to the appeal recently filed briefs in this case. The court has issued an order for oral argument, but has not yet set a date for oral argument. We are unable at this time to predict the likely outcome of the appeals and unable to predict the impact on the Auction. We also are unable to predict whether the litigation will result in any changes to the DE Order or to the DE program, and, if there are changes, whether or not any such changes will be beneficial or detrimental to our interests. However, the relief sought by the petitioners includes overturning the results of Auction 66. If the petitioners are ultimately successful in getting this relief, any licenses granted to us as a result of Auction 66 would be revoked. Our payments to the FCC for the licenses would be refunded, but without interest. If our licenses are revoked we will have been required to pay interest to our lenders on the money paid to the FCC for the AWS licenses, but would not receive interest. The interest expense, which could be substantial, may affect our results of operations and the loss of the Auction 66 licenses could affect our future prospects.
     In connection with the changes to the DE rules, the FCC also adopted in April 2006 a Second Further Notice of Proposed Rulemaking seeking comment on whether additional restrictions should be adopted in its DE program relating to, among other things:
    relationships between designated entities and other communications enterprises based on class of services, financial measures, or spectrum interests;
 
    the need to include other agreements within the definition of impermissible material relationships; and
 
    prohibiting entities or persons with net worth over a particular amount from being considered a DE.
     There can be no assurance what additional changes, if any, to the DE program may be adopted as a result of this rulemaking. Based on the FCC’s latest rulings, we do not expect any future changes in the DE rules to be applied retroactively to Royal Street, but we cannot give any assurance that the FCC will not give any new rules retroactive effect. If additional changes are made to the program that are applied to the current arrangements between Royal Street, C9 Wireless and us, it could have a material adverse effect on our and Royal Street’s operations and financial performance.
     The Communications Act includes provisions authorizing the FCC to restrict ownership levels in us by foreign nationals or their representatives, a foreign government or its representative or any corporation organized under the laws of a foreign country. The law permits indirect foreign ownership of as much as 25% of our equity without the need for any action by the FCC. If the FCC determines it is in the best interest of the general public, the FCC may revoke licenses or require an ownership restructuring if our foreign ownership exceeds the statutory 25% benchmark. However, the FCC generally permits additional indirect foreign ownership in excess of the statutory 25% benchmark particularly if that interest is held by an entity or entities from World Trade Organization member countries. For investors from countries that are not members of the World Trade Organization, the FCC determines if the home country extends reciprocal treatment, called “equivalent competitive opportunities,” to United States entities. If these opportunities do not exist, the FCC may not permit such foreign investment beyond the 25% benchmark. We have adopted internal procedures to assess the nature and extent of our foreign ownership, and we believe that the indirect ownership of our equity by foreign entities is below the benchmarks established by the Communications Act. If we have foreign ownership in excess of the limits, we have the right to acquire the portion of the foreign investment which places us over the foreign ownership restriction. Nevertheless, these foreign ownership restrictions could affect our ability to attract additional equity financing and complying with the restrictions could increase our cost of operations.
General Regulatory Obligations
     The Communications Act and the FCC’s rules impose a number of requirements upon wireless broadband PCS, and in many instances AWS, licensees. These requirements, summarized below, could increase our costs of doing business.

19


Table of Contents

     Federal legislation enacted in 1993 requires the FCC to reduce the disparities in the regulatory treatment of similar mobile services, such as cellular, PCS and Enhanced Specialized Mobile Radio, or ESMR, services. Under this regulatory structure, our wireless broadband PCS and AWS services are classified as CMRS. The FCC regulates providers of CMRS services as common carriers, which subjects us to many requirements under the Communications Act and FCC rules and regulations. The FCC, however, has exempted CMRS offerings from some typical common carrier regulations, such as tariff and interstate certification filings, which allows us to respond more quickly to competition in the marketplace. The 1993 federal legislation also preempted state rate and entry regulation of CMRS providers.
     The FCC permits cellular, broadband PCS, AWS, paging and ESMR licensees to offer fixed services on a co-primary basis along with mobile services. This rule may facilitate the provision of wireless local loop service by CMRS licensees using wireless links to provide local telephone service. The extent of lawful state regulation of such wireless local loop service is undetermined. While we do not presently have a fixed service offering, our network can accommodate such a service. We continue to evaluate our service offerings, which may include a fixed service plan at some point in the future.
     The spectrum allocated for broadband PCS was utilized previously by fixed microwave systems. To foster the orderly clearing of the spectrum, the FCC adopted a transition and cost sharing plan pursuant to which incumbent microwave users could be reimbursed for relocating out of the band and the costs of relocation were shared by the broadband PCS licensees benefiting from the relocation. Under the FCC regulations, DEs were able to pay microwave reimbursed clearing obligations through installment payments. We incurred various microwave relocation obligations pursuant to this transition plan. The transition and cost sharing plans expired in April 2005, at which time remaining microwave incumbents in the broadband PCS spectrum remained obligated to relocate to different spectrum but assumed responsibility for their costs to relocate to alternate spectrum. We have fulfilled all of the relocation obligations (and related payments) directly incurred in our broadband PCS markets. As of December 31, 2006, we had no obligations related to our PCS licenses payable to other carriers under cost sharing plans for microwave relocation in our markets. As a result of the offer to purchase made by Madison Dearborn Capital Partners IV, L.P. and certain affiliates of TA Associates, Inc. in 2005, we ceased being a DE have paid off all remaining microwave clearing obligations to other carriers. This process has taken longer than we anticipated which could give rise to an objection by a carrier to which microwave clearing payments are due.
     In addition, spectrum allocated for AWS currently is utilized by a variety of categories of commercial and governmental users. To foster the orderly clearing of the spectrum, the FCC adopted a transition and cost sharing plan pursuant to which incumbent non-governmental users could be reimbursed for relocating out of the band and the costs of relocation would be shared by AWS licensees benefiting from the relocation. The FCC has established a plan where the AWS licensee and the incumbent non-governmental user are to negotiate voluntarily for three years and then, if no agreement has been reached, the incumbent licensee is subject to mandatory relocation where the AWS licensee can force the incumbent non-governmental licensee to relocate at the AWS licensee’s expense. The spectrum allocated for AWS currently is utilized also by governmental users. The FCC rules provide that a portion of the money raised in Auction 66 will be used to reimburse the relocation costs of governmental users from the AWS band. However, not all governmental users are obligated to relocate. We estimate the costs we may incur to relocate the incumbent licensees in the areas where we have been granted AWS licenses in Auction 66 to be approximately $40 to $60 million, and the time it will take to clear the AWS spectrum in markets where we acquired licenses is uncertain.
     We are obligated to pay certain annual regulatory fees and assessments to support FCC wireless industry regulation, as well as fees supporting federal universal service programs, number portability, regional database costs, centralized telephone numbering administration, telecommunications relay service for the hearing-impaired and application filing fees. These fees are subject to increase by the FCC periodically.
     The FCC requires CMRS providers to implement basic 911 and enhanced, or E-911, emergency services. Our obligation to implement these services is incurred in stages on a market-by-market basis as local emergency service providers request E-911 services. These services allow state and local emergency service providers to better identify and locate callers using wireless services, including callers using special devices for the hearing impaired. We have constructed facilities to implement these capabilities in markets where we have had requests and are in the process of constructing facilities in the markets we launched recently. The FCC also has rules that require us, because we employ a handset-based location technology, to ensure that specified percentages of the handsets in service on the system be location capable. As of December 31, 2005, 95% of our handsets were required to be

20


Table of Contents

location-capable and we met this requirement. Failure to maintain compliance with the FCC’s E-911 requirements can subject us to significant penalties. The extent to which we must deploy E-911 services affects our capital spending obligations. In 1999, the FCC amended its rules to no longer require compensation by the state to carriers for E-911 costs and to expand the circumstances under which wireless carriers may be required to offer E-911 services to the public safety agencies. States in which we do business may limit or eliminate our ability to recover our E-911 costs. Federal legislation enacted in 1999 may limit our liability for uncompleted 911 calls to a similar level to wireline carriers in our markets.
     Federal law requires CMRS carriers to provide law enforcement agencies with support for lawful wiretaps. Federal law also requires compliance with wiretap-related record-keeping and personnel-related obligations. Complying with these E-911 and law enforcement wiretap requirements may require systems upgrades creating additional capital obligations for us and additional personnel, a process which may cost us additional expense which we may not be able to recover. Our customer base may be subject to a greater percentage of law enforcement requests than those of other carriers and that the resulting expenses incurred by us to cooperate with law enforcement are proportionately greater.
     Because the availability of telephone numbers is dwindling, the FCC has adopted number pooling rules that govern how telephone numbers are allocated. Number pooling is mandatory inside the wireline rate centers where we have drawn numbers and that are located in counties included in the top 100 metropolitan statistical areas, or MSAs, as defined by FCC rules. We have implemented number pooling and support pooled number roaming in all of our markets which are included in the top 100 MSAs. The FCC also has authorized states to start limited numbering administration to supplement federal requirements and some of the states where we provide service have been authorized by the FCC to start limiting numbering administration.
     In addition, the FCC has ordered all telecommunications carriers, including CMRS carriers, to provide telephone number portability enabling subscribers to keep their telephone numbers when they change telecommunications carriers, whether wireless to wireless or, in some instances, wireline to wireless, and vice versa. Under these local number portability rules, a CMRS carrier located in one of the top 100 MSAs must have the technology in place to allow its customers to keep their telephone numbers when they switch to a new carrier. Outside of the top 100 MSAs, CMRS carriers receiving a request to allow end users to keep their telephone numbers must be capable of doing so within six months of the request or within six months of November 24, 2003, whichever is later. In addition, all CMRS carriers are required to support nationwide roaming for customers retaining their numbers. We currently support number portability in all of our markets.
     FCC rules provide that all local exchange carriers must, upon request, enter into mutual or reciprocal compensation arrangements with CMRS carriers for the exchange of local traffic, under which each carrier compensates the other for terminated local traffic originating on the compensating carrier’s network. Local traffic is defined for purposes of the reciprocal compensation arrangement between local exchange carriers and CMRS carriers as intra-MTA traffic, and thus the FCC’s reciprocal compensation rules apply to any local traffic originated by a CMRS carrier and terminated by a local exchange carrier within the same MTA and vice versa, even if such traffic is interexchange. While these rules provide that local exchange carriers may not charge CMRS carriers for facilities used by CMRS carriers to terminate local exchange carriers’ traffic, local exchange carriers may charge CMRS carriers for facilities used to transport and terminate CMRS traffic and for facilities used for transit purposes to carry CMRS carrier traffic to a third carrier. FCC rules also provide that, on the CMRS carrier’s request, incumbent local exchange carriers must exchange local traffic with CMRS carriers at rates based on the FCC’s costing rules; rates are set by state public utility commissions applying the FCC’s rules. The rules governing CMRS interconnection are under review by the FCC in a rulemaking proceeding, and we cannot be certain whether or not there will be material changes in the applicable rules, and if there are changes, whether they will be beneficial or detrimental to us.
     Before 2005, some local exchange carriers claimed a right by filing a state tariff to impose unilateral charges on CMRS carriers for the termination of CMRS carriers’ traffic on the local exchange carrier’s network, often at above-cost rates. In 2005, the FCC issued a Report and Order holding that, on a going forward basis, no local exchange carrier was permitted to unilaterally impose tariffed rates for the termination of a CMRS carrier’s traffic. This Report and Order imposed on CMRS carriers an obligation to engage in voluntary negotiation and arbitration with incumbent local exchange carriers similar to those imposed on the incumbent local exchange carriers pursuant to Section 252 of the Communications Act. Further, the FCC found that its prior rules did not preclude incumbent local exchange carriers from imposing unilateral charges pursuant to tariff for the period prior to

the effective date of the Report and Order. Finally, the Report and Order found that, once an incumbent local exchange carrier requested negotiation of an interconnection arrangement, both carriers are obligated to begin paying the FCC’s default rates for all traffic exchanged after the request for negotiation. Several CMRS carriers and incumbent local exchange carriers have appealed the Report and Order and we have sought clarification on certain aspects of the Report and Order. In the meantime, a number of local exchange carriers and incumbent local exchange carriers have demanded that we pay bills for traffic exchanged in the past and we are evaluating those demands. We may pay some portion of these amounts, which may be material. Also, a number of local exchange carriers have requested that we enter into negotiations for interconnection agreements and, as a result of such negotiations, we may be obligated to pay amounts to settle prior claims and on a going forward basis, and such amounts may be material. Also, other local exchange companies have threatened to sue us if agreements governing termination compensation are not reached. We generally have been successful in negotiating arrangements with carriers with whom we exchange traffic; however, our business could be adversely affected if the rates some carriers charge us for terminating our customers’ traffic ultimately prove to be higher than anticipated. In one case, a complaint has been filed by a CLEC against us before the FCC claiming a right to terminating compensation payments on a going forward basis and going backward basis at a rate that we consider to be excessive. We are vigorously defending against the complaint, but cannot predict the outcome at this time. An adverse outcome could be material.
     The FCC has adopted rules requiring interstate communications carriers, including CMRS carriers, to “make an equitable and non-discriminatory contribution” to a Universal Service Fund, or USF, that reimburses communications carriers providing basic communications services to users receiving services at subsidized rates. We have made these FCC-required payments. The FCC recently started a rulemaking proceeding to solicit public comment on ways of reforming both how it assesses carrier USF contributions and how carriers may recover their costs from customers and some of the proposals may cause the amount of USF contributions required from us and our customer to increase. Effective April 1, 2003, the FCC prospectively forbade carriers from recovering administrative costs related to administering the required universal service assessments from customers as USF charges. The FCC’s rules require carriers’ USF recovery charges to customers not exceed the assessment rate the carrier pays times the proportion of interstate telecommunications revenue on the bill. We are currently in compliance with these requirements.
     Wireless broadband carriers may be designated as Eligible Telecommunications Carriers, or ETCs, and may receive universal service support for providing service to customers using wireless service in high cost areas. Other wireless broadband carriers operating in states where we operate have obtained or applied for ETC status. Such other carriers’ receipt of universal service support funds may affect our competitive status in a particular market by allowing our competitors to offer service at a lower rate. We may decide in the future to apply for this designation in certain qualifying high cost areas where we provide wireless services. If we are approved, these payments would be an additional revenue source that we could use to support the services we provide in high cost areas.
     CMRS carriers are exempt from the obligation to provide equal access to interstate long distance carriers. However, the FCC has the authority to impose rules requiring unblocked access through carrier identification codes or 800/888 numbers to long distance carriers so CMRS customers are not denied access to their chosen long distance carrier, if the FCC determines the public interest so requires. Our customers have access to alternative long distance carriers using toll-free numbers.
     FCC rules also impose restrictions on a telecommunications carrier’s use of customer proprietary network information, or CPNI, without prior customer approval, including restrictions on the use of information related to a customer’s location. The FCC recently began an investigation into whether CMRS carriers are properly protecting the CPNI of their customers against unauthorized disclosure to third parties. In February 2006, the FCC requested that all CMRS carriers provide a certificate from an officer of the CMRS carrier based on personal knowledge that the CMRS carrier was in compliance with all CPNI rules. We have provided such a certificate. The FCC also has proposed substantial fines on certain wireless carriers for their failure to comply with the FCC’s CPNI rules. We believe that our current practices are consistent with existing FCC rules on CPNI, and do not foresee new costs or limitations on our existing practices as a result of the current FCC rules in that area. However, in February 2006, the FCC also adopted a notice of proposed rulemaking seeking comment on a variety of issues related to customer privacy, including what additional security measures may be warranted to protect a customer’s CPNI. Congress and state legislators also are in the process of enacting legislation which addresses the use and protection of CPNI which may impact our obligations. For example, Congress recently enacted the Telephone Records and Privacy Protection

22


Table of Contents

Act of 2006, which imposes criminal penalties upon persons who purchase without a customer’s consent, or use fraud to gain unauthorized access to, telephone records. The FCC’s proposed rules, if adopted or modified, and the recent and pending legislation (if enacted) may require us to change how we protect our customer’s CPNI and could require us to incur additional costs or change our business practices or processes, which costs and changes may be material.
     Telecommunications carriers are required to make their services accessible to persons with disabilities. These FCC rules generally require service providers to offer equipment and services accessible to and usable by persons with disabilities, if readily achievable, and to comply with FCC-mandated complaint/grievance procedures. These rules are largely untested and are subject to interpretation through the FCC’s complaint process. While these rules principally focus on the manufacturer of the equipment, we could have costly new requirements imposed on us and, if we were found to have violated the rules, be subject to fines, which fines could be material. As a related matter, on July 10, 2003, the FCC issued an order requiring digital wireless phone manufacturers and wireless service providers (including us) to take steps ensuring the availability of hearing aid compatible digital wireless phones. Specifically, the FCC mandated that non-Tier 1 CMRS carriers, such as us, are required under the FCC’s current rules to offer to its customers at least two wireless digital phones for each air interface used by it that meet the FCC hearing aid-compatibility requirements. We currently are in compliance with these requirements. By February 18, 2008, half of the digital wireless handsets that we offer for each air interface must meet the FCC’s hearing aid-compatibility requirements. Since there has been consolidation in the digital wireless handset manufacturers industry, we may have difficulty securing the necessary handsets in order to meet the FCC’s requirements. In addition, since we are required to offer these hearing aid-compatible wireless phones for each air interface we provide, this requirement may limit our ability to offer services using new air interfaces other than CDMA 1XRTT, may limit the number of handsets we can offer, or may increase the costs of handsets for those new air interfaces. Further, to the extent that the costs of such handsets are more than non-hearing aid-compatible digital wireless handsets, it may decrease demand for our services, decrease the number of wireless phones we can offer to our customers, or increase our selling costs if we choose to subsidize the cost of the hearing aid-compatible handsets.
     The FCC has determined that long distance or interexchange service offerings from CMRS providers are subject to Communications Act rate averaging and rate integration requirements. Rate averaging requires us to average our intrastate long distance CMRS rates between rural and high cost areas and urban areas. The FCC has delayed implementation of rate integration requirements for wide area rate plans pending further reconsideration of its rules, and has also delayed a requirement that CMRS carriers integrate their rates among CMRS affiliates. Other aspects of the FCC’s rules have been vacated by the United States Court of Appeals for the District of Columbia Circuit, and are subject to further consideration by the FCC. There is a pending proceeding for the FCC to determine how integration requirements apply to CMRS offerings, including single rate plans. Our pricing flexibility is reduced to the extent we offer services subject to these requirements, and we cannot assure you that the FCC will decline imposing these requirements on us.
     Antenna structures used by us and other wireless providers are subject to FCC rules implementing the National Environmental Policy Act and the National Historic Preservation Act. Under these rules, construction cannot begin on any structure that may significantly affect the human environment or that may affect historic properties until the wireless provider has filed an environmental assessment with and obtained approval from the FCC. Processing of environmental assessments can delay construction of antenna facilities, particularly if the FCC determines that additional information is required or if community opposition arises. In addition, several environmental groups have unsuccessfully requested changes to the FCC’s environmental processing rules, challenged specific environmental assessments as failing statutory requirements and sought to have the FCC conduct a comprehensive assessment of antenna tower construction environmental effects. The FCC also is considering the impact that communications facilities, including wireless towers and antennas, may have on migratory birds. In August of 2003, the FCC initiated a rulemaking proceeding seeking information on whether rule changes should be adopted to reduce the risk of migratory bird collisions with commercial towers. The FCC released a Notice of Proposed Rulemaking in this proceeding on November 7, 2006, in which the FCC tentatively concludes that medium-intensity white strobe lights should be considered the preferred system in place of red obstruction lighting systems to the maximum extent possible without compromising safety. The FCC also seeks comments on the possible adoption of various other measures that might serve to mitigate the impact of communications towers on migratory birds. In the meantime, there are a variety of federal and state court actions in which citizen and environmental groups have sought to deny tower approvals based upon potential adverse impacts to migratory birds.

Although we use antenna structures that are owned and maintained by third parties, the results of these FCC and court proceedings could have an impact on our efforts to secure access to particular towers, or the costs of access.
     The location and construction of PCS antennas, base stations and towers also are subject to FCC and Federal Aviation Administration regulations, federal, state and local environmental regulation, and state and local zoning, land use and other regulation. Before we can put a system into commercial operation, we, or the tower owner in the case of leased sites, must obtain all necessary zoning and building permit approvals for the cell site and microwave tower locations. The time needed to obtain necessary zoning approvals and state permits varies from market to market and state to state and, in some cases, may materially delay our ability to provide service. Variations also exist in local zoning processes. Further, certain municipalities impose severe restrictions and limitations on the placement of wireless facilities which may impede our ability to provide service in that area. In 2002, the Board of Supervisors for the City and County of San Francisco, or the City of San Francisco, denied certain applications to construct three sites in the City of San Francisco. The City of San Francisco claimed that additional facilities were not necessary because adequate services are available from other wireless carriers. In July 2002, we filed suit against the City of San Francisco and its Board of Supervisors based on their denial of our applications. The trial was conducted in late March 2006 and early April 2006. In June 2006, the court found in favor of the City of San Francisco and denied our applications. The court clarified that a gap in coverage existed, but that we had not used the least restrictive means to provide service in the area. None of the parties to the proceeding have appealed and the time to bring an appeal has expired. A failure or inability to obtain necessary zoning approvals or state permits, or to satisfy environmental rules may make construction impossible or infeasible on a particular site, might adversely affect our network design, increase our network design costs, require us to use more costly alternative technologies, such as distributed antenna systems, reduce the service provided to our customers, and affect our ability to attract and retain customers.
     In 2004, the FCC initiated a proceeding to update and modernize its systems for distributing emergency broadcast alerts. Television stations, radio broadcasters and cable systems currently are required to maintain emergency broadcast equipment capable of retransmitting emergency messages received from a federal agency. As part of its attempts to modernize the emergency alert system, the FCC in its proceeding is addressing the feasibility of requiring wireless providers, such as us, to distribute emergency information through wireless networks. Unlike broadcast and cable networks, however, our infrastructure and protocols — like those of all other similarly-situated wireless broadband CMRS carriers — are optimized for the delivery of individual messages on a point-to-point basis, and not for delivery of messages on a point-to-multipoint basis, such as all subscribers within a defined geographic area. While multiple proposals have been discussed in the FCC proceeding, including limited proposals to use existing short messaging service capabilities on a short-term basis, the FCC has not yet ruled and therefore we are not able to assess the short- and long-term costs of meeting any future FCC requirements to provide emergency and alert service, should the FCC adopt such requirements. Adoption of such requirements, however, could require new components within our network and transmission infrastructure and also require consumers to purchase new handsets. Congress recently passed the Warning, Alert, and Response Network Act as part of the Security and Accountability For Every Port Act of 2006. In this Act, which was recently signed into law, Congress provided for the establishment, within 60 days of enactment, of an advisory committee to provide recommendations to the FCC regarding technical standards and protocols under which electing commercial mobile radio service, or CMRS, providers may offer subscribers the capability of receiving emergency alerts. The FCC is required to complete a proceeding to adopt relevant technical standards, protocols, procedures, and other technical requirements based on the recommendations of such Advisory Committee necessary to enable alerting capability for CMRS providers that voluntarily elect to transmit emergency alert. Under the Act, a CMRS carrier can elect not to participate in providing such alerting capability. If a CMRS carrier elects to participate, the carrier may not charge separately for the alerting capability and the CMRS carrier’s liability related to, or any harm resulting from, the transmission of, or failure to transmit, an emergency alert is limited. The FCC is obligated to complete its rulemaking implementing such rules within a relatively short period of time after receiving the recommendations from the advisory committee. Until the FCC promulgates rules, we do not know if they will adopt such requirements, and if it does, what their impact will be on our infrastructure and service.
     The FCC historically has required that CMRS providers permit customers of other carriers to roam “manually” on their networks, for example, by supplying a credit card number, provided that the roaming customer’s handset is technically capable of accessing the roamed-on network. The FCC recently initiated a notice of proposed rulemaking seeking comments on whether automatic roaming services are considered common carrier services, whether CMRS carriers have an obligation to offer automatic roaming services to other carriers, whether carriers have an obligation to provide non-voice roaming services, and what rates a carrier may charge for roaming

24

services. The FCC previously initiated roaming proceedings on similar issues but failed to resolve these issues. Roaming rights are important to us because we have a limited service area and must rely on other carriers in order to offer roaming outside our existing service areas. We have commented in this proceeding in support of an FCC rule requiring carriers to honor requests for automatic roaming at reasonable, non-discriminatory rates. However, we cannot predict the likely outcome of this proceeding or the likely timing of an FCC ruling. If the FCC decides not to require automatic roaming at reasonable non-discriminatory rates, or limits roaming to voice services only, we may have difficulty attracting and retaining certain groups of customers which could have an adverse impact on our business.
     In September of 2004, the FCC issued a Report and Order and Further Notice of Proposed Rulemaking and adopted several measures designed to increase carrier flexibility, reduce regulatory costs and to promote access to capital and spectrum for entities seeking to provide or improve wireless service to rural areas, including the relaxation of the FCC rule that prohibited a carrier from having any interest in both the Block A and Block B cellular licenses in a common market. These rule changes create potential opportunities for us if we seek to extend our service to rural markets, but also could benefit our competitors.
     On November 20, 2006, the Copyright Office of the Library of Congress, or the Copyright Office, released the final rules in its triennial review of the exemptions to the prohibition on circumvention of copyright protection systems for access control technologies, or Triennial Review, contained in the Digital Millennium Copyright Act, or DMCA. In 1998, Congress enacted the DMCA, which among other things amended the United States Copyright Act to add a section prohibiting the circumvention of technological measures employed to protect a copyrighted work, or access control. In addition, the Copyright Office has the authority to exempt certain activities which otherwise might be prohibited by that section for a period of three years when users are (or in the next three years are likely to be) adversely affected by the prohibition in their ability to make noninfringing uses of a class of copyrighted work. Many carriers, including us, routinely place software locks on their wireless handsets which prevent a customer from using a wireless handset sold by one carrier on another carrier’s system. In its Triennial Review, the Copyright Office determined that these software locks on wireless handsets are access controls which adversely affect the ability of consumers to make noninfringing use of the software on their wireless handsets. As a result, the Copyright Office found that a person could circumvent such software locks and other firmware that enable wireless handsets to connect to a wireless telephone network when such circumvention is accomplished for the sole purpose of lawfully connecting the wireless handset to another wireless telephone network. A wireless carrier has filed suit in the United States District Court in Florida to reverse the Copyright Office’s decision. This exemption is effective from November 27, 2006 through October 27, 2009 unless extended by the Copyright Office.
     This ruling, if upheld, could allow customers to use their wireless handsets on the networks of other carriers. Since many of our competitors generally subsidize their wireless handsets substantially more than we do, customers of our competitors may find it attractive to bring their phones to us for activation. This may result in us experiencing lower costs to add customers. This ruling may also allow our customers who are dissatisfied with our service to utilize the services of our competitors without having to purchase a new wireless handset. The ability of our customers to leave our service and use their wireless handsets to receive a competitor’s service may have an adverse material impact on our business. In addition, since our subsidy for handsets to our distribution partners is incurred in advance, we may experience higher distribution costs resulting from wireless handsets not being activated or maintained on our network, which costs may be material.
     In a February 20, 2007, filing, a provider of VoIP services asked the FCC to issue a declaratory ruling that would give wireless customers the right to utilize any device of their choice to access a wireless network as long as the devise did not cause interference or network degradation. This so-called “Carterfone Rule” is opposed by many wireless companies and the principal wireless industry association, but may be considered by the FCC. The proponent also requested that the FCC initiate proceedings to determine whether the practices of wireless carriers comport with the Carterfone Rule.
     On March 23, 2007, the FCC released a declaratory ruling finding that wireless broadband Internet access service is an information service under the Communications Act of 1934, as amended, or the Communications Act. In addition, the FCC found that the transmission component of wireless broadband Internet access service is telecommunications and that the offering of a telecommunications transmission component as part of a functionally integrated Internet access service offering is not a telecommunications service under the Communications Act. Further, the FCC found that mobile wireless broadband Internet access service is not a “commercial mobile service” under Section 332 of the Act. Finally, the FCC defined broadband Internet access for this purpose as service at

25

speeds in excess of 200 kbps in at least one direction. This ruling eliminates any common carrier obligations with respect to the provision of mobile wireless broadband Internet access services and could have a material impact on our ability to negotiate roaming agreements with other wireless carriers which include the provision of mobile wireless broadband Internet access services while roaming on the other carrier’s network. In addition, this ruling could allow our competitors and us greater flexibility in the pricing and terms and conditions of this service.
State, Local and Other Regulation
     The Communications Act preempts state or local regulation of market entry or rates charged by any CMRS provider. As a result, we are free to establish rates and offer new products and services with minimum state regulation. However, states may continue regulating “other terms and conditions” of wireless service, and certain states where we operate maintain additional oversight jurisdiction, primarily focusing upon consumer protection issues and resolution of customer complaints. In addition, several state authorities have initiated actions or investigations of various wireless carrier practices. The outcome of these proceedings is uncertain and could require us to change our marketing practices, ultimately increasing state regulatory authority over the wireless industry. State and local governments also may manage public rights of way and can require fair and reasonable compensation from telecommunications carriers, including CMRS providers, for the use of such rights of any, so long as the government publicly discloses such compensation.
     A dispute exists between the FCC and certain state public utility commission advocates as to whether the FCC’s preemptive rights over rates allows the FCC to prevent states from prohibiting the use of separate line items on wireless bills for charges that are not mandated by federal, state or local law. The FCC ruled in 2005 that states were preempted from requiring or prohibiting the use of non-misleading line items on wireless bills. In 2006, the United States Court of Appeals for the Eleventh Circuit vacated the FCC decision. A similar case is currently pending before the United States Court of Appeals for the Ninth Circuit. Several parties have announced an intention to seek review of the issues in the U.S. Supreme Court. The outcome of these cases, which we are unable to predict at this time, could affect the extent to which our CMRS services are subject to state regulations that may cause us to incur additional costs.
     The California Public Utilities Commission, or CPUC, in early 2006 adopted consumer protection rules replacing an earlier consumer bill of rights. The new consumer bill of rights applies to “telecommunications services” subject to the CPUC’s jurisdiction — they do not replace and only supplement existing requirements that carriers have under federal and state law, tariffs, other orders and decisions of the FCC or the CPUC, and FCC requirements. The consumer bill of rights establishes seven rights (freedom of choice, disclosure, privacy, public participation and enforcement, accurate bills and dispute resolution, nondiscrimination, and public safety) and also includes rules on CPUC staff requests for information; worker identification; E-911 access; slamming rules (e.g., change of a subscriber’s telecommunications service without authorization) with some modifications to existing slamming rules; and new cramming rules (e.g., placement of unauthorized charges on a telecommunications bill) that apply to all charges on a telephone bill (and eliminates the interim opt-in rules for non-communications relating services). The cramming rules generally reiterate requirements that already exist under the law with some additions. The consumer bill of rights does not create a private right of action or liability that would not exist absent the rules. We have reviewed the consumer bill of rights and believe that we are in compliance.
     We cannot give any assurance that the consumer bill of rights will not cause us to spend additional funds or complicate our marketing and sales programs which may have a material adverse impact on our operations in California. We cannot assure you that any state or local regulatory requirements currently applicable to our systems will not be changed in the future or that regulatory requirements will not be adopted in those states and localities which currently have none. Such changes could impose new obligations on us that would adversely affect our operating results.
Future Regulation
     From time to time, federal or state legislators propose legislation and federal or state regulators propose regulations that could affect us, either beneficially or adversely. We cannot assure you that federal or state governments will not enact legislation or that the FCC or other federal or state regulator will not adopt regulations or take other action that might adversely affect us. Changes such as the FCC allocating additional radio spectrum for services competing with our business or granting existing licensees of other services flexibility to offer mobile wireless services could adversely affect our operating results.

Item 1A. Risk Factors
Risks Related to Our Business
Our business strategy may not succeed in the long term.
     A major element of our business strategy is to offer consumers a service that allows them to make unlimited local calls and, depending on the service plan selected, long distance calls, from within our service area and to receive unlimited calls from any area for a flat monthly rate without entering into a long-term service contract. This is a relatively new approach to marketing wireless services and it may not prove to be successful in the long term or deployable in geographic areas we have acquired but not launched or geographic areas we may acquire in the future. Some companies that have offered this type of service in the past have not been successful. From time to time, we evaluate our service offerings and the demands of our target customers and may amend, change, discontinue or adjust our service offerings or trial new service offerings as a result. These service offerings may not be successful or prove to be profitable.
We have limited operating history and have launched service in a limited number of metropolitan areas. Accordingly, our performance to date may not be indicative of our future results or our performance in future markets we launch.
     We began offering service in the first quarter of 2002, and we had no revenues before that time. Consequently, we have a limited operating and financial history upon which to evaluate our financial performance, business plan execution and ability to succeed in the future. You should consider our prospects in light of the risks, expenses and difficulties we may encounter, including those frequently encountered by new companies competing in rapidly evolving and highly competitive markets. If we are unable to execute our plans and grow our business, our financial results will be adversely affected. Our business strategy involves expanding into new geographic areas beyond our Core Markets and these geographic areas may present competitive challenges different from those encountered in our Core Markets. Our financial performance in new geographic areas, including our Expansion Markets and Auction 66 Markets, may not be as positive as our Core Markets.
We face intense competition from other wireless and wireline communications providers, and potential new entrants, which could adversely affect our operating results and hinder our ability to grow.
     We compete directly in each of our markets with (i) other facilities-based wireless providers, such as Verizon Wireless, Cingular Wireless, Sprint Nextel, and T-Mobile and their prepaid affiliates or brands, (ii) non- facilities based mobile virtual network operators, or MVNOs, such as Virgin Mobile USA and Amp’d Mobile, (iii) incumbent local exchange carriers, such as AT&T and Verizon, as a mobile alternative to traditional landline service and (iv) competitive local exchange carriers or Voice-Over-Internet-Protocol, or VoIP, service providers, such as Vonage, Time Warner, Comcast, McLeod USA, Clearwire and XO Communications, as a mobile alternative to wired service. We also may face competition from providers of an emerging technology known as Worldwide Interoperability for Microwave Access, or WiMax, which is capable of supporting wireless transmissions suitable for mobility applications. Also, certain mobile satellite providers recently have received authority to offer ancillary terrestrial service and a coalition of companies which includes DIRECTV Group, EchoStar, Google, Inc., Intel Corp. and Yahoo! has indicated its desire to establish next generation wireless networks and technologies in the 700 MHz band. In addition, VoIP service providers have indicated that they may offer wireless services over a Wi-Fi/Cellular network to complete directly with us for the provisioning of wireless services. Many major cable television service providers, including Comcast, Time Warner Cable, Cox Communications and Bright House Networks, also have indicated their intention to offer suites of service, including wireless service, often referred to as the “Quadruple Play,” and are actively pursuing the acquisition of spectrum or leasing access to spectrum to implement those plans. These cable companies formed a joint venture along with Sprint Nextel called SpectrumCo LLC, or SpectrumCo, which bid on and acquired 20 MHz of advanced wireless service, or AWS, spectrum in a number of major metropolitan areas throughout the United States, including all of the major metropolitan areas which comprise our Core, Expansion and Auction 66 Markets. Many of our current and prospective competitors are, or are affiliated with, major companies that have substantially greater financial, technical, personnel and marketing resources than we have (including spectrum holdings, brands and intellectual property) and larger market share than we have, which may affect our ability to compete successfully. These competitors often have greater name and brand recognition and established relationships with a larger base of current and potential customers and, accordingly, we may not be able to compete successfully. In some markets, we also compete with local or regional carriers, such as

27


Table of Contents

Leap Wireless International, or Leap Wireless, and Sure West Wireless, some of whom have or may develop fixed-rate unlimited service plans similar to ours.
     Sprint Nextel recently announced that it will offer an unlimited local calling plan under its Boost brand in certain of the geographic areas in which we offer service. In response, in certain of our markets we have added additional features to our existing service plans. Currently, in our San Francisco, Sacramento, and Dallas/Ft. Worth metropolitan areas we have added to the $35 service plan unlimited long distance in the continental United States, to the $40 service plan unlimited short message and multimedia message services, and to the $45 service plan unlimited mobile Internet browsing and international short message service. The Sprint Nextel calling plans may increase our churn and decrease demand for our services in those metropolitan areas where they offer their unlimited local calling plan. In addition, as a result of the changes in our service plans, we may experience lower revenues, lower ARPU and lower Adjusted EBITDA in the affected metropolitan areas. If Sprint Nextel expands its unlimited local calling plan into other metropolitan areas or if other carriers institute similar service plans, we may make similar changes to our service plans in our other metropolitan areas, add additional features or services to our existing service plans, or make other changes to our service plans, all of which could have a material adverse impact on our future financial results.
     We expect that increased competition will result in more competitive pricing, slower growth and increased churn of our customer base. Our ability to compete will depend, in part, on our ability to anticipate and respond to various competitive factors and to keep our costs low. The competitive pressures of the wireless telecommunications industry have caused, and may continue to cause, other carriers to offer service plans with increasingly large bundles of minutes of use at increasingly lower prices and rate plans with unlimited nights and weekends. These competitive plans could adversely affect our ability to maintain our pricing and market penetration and maintain and grow our customer base.
We may face additional competition from new entrants in the wireless marketplace, many of whom may have significantly more resources than we do.
     Certain new entrants with significant financial resources participated in Auction 66 and were designated as the high bidder on spectrum rights in geographic areas served by us. For example, SpectrumCo acquired 20 MHz of spectrum in all of the metropolitan areas which comprise our Core, Expansion and Auction 66 Markets. In addition, Leap Wireless offers fixed-rate unlimited service plans similar to ours and acquired spectrum which overlaps some of the metropolitan areas we serve or plan to serve. These licenses could be used to provide services directly competitive with our services.
     The auction and licensing of new spectrum, including the spectrum recently auctioned by the FCC in Auction 66, may result in new competitors and/or allow existing competitors to acquire additional spectrum, which could allow them to offer services that we may not technologically or cost effectively be able to offer with the licenses we hold or to which we have access. The FCC has already designated an additional 60 MHz of spectrum in the 700 MHz band which may be used to offer services competitive with the services we offer or plan to offer. Furthermore, the FCC may pursue policies designed to make available additional spectrum for the provision of wireless services in each of our metropolitan areas, which may increase the number of wireless competitors and enhance the ability of our wireless competitors to offer additional plans and services that we may be unable to successfully compete against.
Some of our competitors have technological or operating capabilities that we may not be able to successfully compete with in our existing markets or any new markets we may launch.
     Some of the carriers we compete against provide wireless services using cellular frequencies in the 800 MHz band. These frequencies enjoy propagation advantages over the PCS frequencies we use, which may cause us to have to spend more capital than our competitors in certain areas to cover the same area. In addition, the FCC plans to auction additional spectrum in the 700 MHz band which will have similar characteristics to the 800 MHz cellular frequencies. Many of the wireless carriers against whom we compete have service area footprints substantially larger than our footprint. In addition, certain of our competitors are able to offer their customers roaming services over larger geographic areas and at rates lower than the rates we can offer. Our ability to replicate these roaming service offerings at rates which will make us, or allow us to be, competitive is uncertain at this time.

     Certain carriers we compete against, or may compete against in the future, are multi-faceted telecommunications service providers which, in addition to providing wireless services, are affiliated with companies that provide local wireline, long distance, satellite television, Internet, media, content, cable television and/or other services. These carriers are capable of bundling their wireless services with other telecommunications services and other services in a package of services that we may not be able to duplicate at competitive prices.
     We also compete with companies that use other communications technologies, including paging and digital two-way paging, enhanced specialized mobile radio and domestic and global mobile satellite service. These technologies may have certain advantages over the technology we use and may ultimately be more attractive to our existing and potential customers. We may compete in the future with companies that offer new technologies and market other services that we do not offer or may not be able to offer. Some of our competitors do or may offer these other services together with their wireless communications service, which may make their services more attractive to customers. Energy companies and utility companies are also expanding their services to offer communications services.
     In addition, we compete with companies that take advantage of the unlicensed spectrum that the FCC is increasingly allocating for use. Certain technical standards are being prepared, including Worldwide Interoperability for Microwave Access, or WiMax, which may allow carriers to offer services competitive with ours in the unlicensed spectrum. The users of this unlicensed spectrum do not have the exclusive use of licensed spectrum, but they also are not subject to the same regulatory requirements that we are and, therefore, may have certain advantages over us.
We may face increased competition from other fixed rate unlimited plan competitors in our existing and new markets.
     We currently overlap with Leap Wireless and Sure West Wireless, who are fixed-rate unlimited service plan wireless carriers providing service in the Sacramento, Modesto and Merced, California basic trading areas. In Auction 66, the FCC auctioned 90 MHz of spectrum in each geographic area of the United States including the areas in which we currently hold or have access to licenses. Leap Wireless also acquired licenses in or has been announced as the high bidder in Auction 66 in some of the same geographic areas in which we currently hold or have access to licenses or in which we were granted licenses as a result of Auction 66. In addition to Leap Wireless, other licensees who have PCS spectrum or acquired spectrum in Auction 66 also may decide to offer fixed-rate unlimited wireless service offerings. In addition, Sprint Nextel recently announced that it is launching an unlimited local calling plan under its Boost brand in certain of the markets in which we offer service. Other national wireless carriers may also decide in the future to offer fixed-rate unlimited wireless service offerings. In addition, we may not be able to launch fixed-rate unlimited service plans ahead of our competition in our new markets. As a result, we may experience lower growth in such areas, may experience higher churn, may change our service plans in affected markets and may incur higher costs to acquire customers, which may materially and adversely affect our financial performance in the future.
A patent infringement suit has been filed against us by Leap Wireless which could have a material adverse effect on our business or results of operations.
     On June 14, 2006, Leap Wireless and Cricket Communications, Inc., or collectively Leap, filed suit against us in the United States District Court for the Eastern District of Texas, Marshall Division, Civil Action No. 2-06CV-240-TJW and amended on June 16, 2006, for infringement of U.S. Patent No. 6,813,497 “Method for Providing Wireless Communication Services and Network and System for Delivering of Same,” or the ’497 Patent, issued to Leap. The complaint seeks both injunctive relief and monetary damages for our alleged infringement of such patent.
     If Leap is successful in its claim for injunctive relief, we could be enjoined from operating our business in the manner we operate currently, which could require us to redesign our current networks, to expend additional capital to change certain of our technologies and operating practices, or could prevent us from offering some or all of our services using some or all of our existing systems. In addition, if Leap is successful in its claim for monetary damage, we could be forced to pay Leap substantial damages for past infringement and/or ongoing royalties on a portion of our revenues, which could materially adversely impact our financial performance. If Leap prevails in its action, it could have a material adverse effect on our business, financial condition and results of operations. Moreover, the actions may consume valuable management time, may be very costly to defend and may distract management attention away from our business.

The Department of Justice has informally stated that it would carefully scrutinize any statement by us in support of any future efforts by us to acquire divestiture assets and as a result we may have difficulty acquiring spectrum in the future.
     We acquired the PCS spectrum for the Dallas/Ft. Worth and Detroit Expansion Markets from Cingular Wireless as a result of a consent decree entered into between Cingular Wireless, AT&T Wireless and the United States Department of Justice, or the DOJ. When we acquired the spectrum, we had certain expectations which were communicated to the DOJ about how we would use the spectrum, including expectations about constructing a combined 1XRTT/EV-DO network on the spectrum capable of supporting data services. Although we have constructed a combined 1XRTT/EV-DO network in those markets, we expected to be able to support our services as demand increased by upgrading the networks to a EV-DO Revision A with VoIP when available. Based upon our discussions at the time with our network vendor, we anticipated that these upgrades would be available in 2006.
     As a result of a delay in the availability of EV-DO Revision A with VoIP, we contacted the DOJ in September 2006 to inform them that we had determined that it was necessary for us to redeploy the EV-DO network assets at certain cell sites in those markets to 1XRTT in order to serve our existing customers. The DOJ responded with an informal letter, which the Company received in November 2006, expressing concern over our use of the spectrum and requesting certain information regarding our construction of our network facilities in these markets, our use of EV-DO, and the services we are providing in the Dallas/Ft. Worth and Detroit Expansion Markets. We have responded to the initial DOJ request and subsequent follow-up requests. On March 23, 2007, the DOJ sent us a letter in which they did not request any further information from us but stated that the DOJ would carefully scrutinize any statement by us in support of any future efforts by us to acquire divestiture assets. This may make it more difficult for us to acquire any spectrum in the future which may be available as a result of a divesture required by the DOJ. This also does not preclude the DOJ from taking any further action against the Company. We cannot predict at this time whether the DOJ will pursue this matter any further and, if they do, what actions they may take or what the outcome may be.
If we experience a higher rate of customer turnover than we have forecasted, our costs could increase and our revenues could decline, which would reduce our profits.
     Our average monthly rate of customer turnover, or churn, for the year ended December 31, 2006 was approximately 4.6%. A higher rate of churn could reduce our revenues and increase our marketing costs to attract the replacement customers required to sustain our business plan, which could reduce our profit margin. In addition, we may not be able to replace customers who leave our service profitably or at all. Our rate of customer churn may be affected by several factors, including the following:
    network coverage;
 
    reliability issues, such as dropped and blocked calls and network availability;
 
    handset problems;
 
    lack of competitive regional and nationwide roaming and the inability of our customers to cost effectively roam onto other wireless networks;
 
    affordability;
 
    supplier or vendor failures;
 
    customer care concerns;
 
    lack of early access to the newest handsets;
 
    wireless number portability requirements that allow customers to keep their wireless phone number when switching between service providers;
 
    our inability to offer bundled services or new services offered by our competitors; and

30


Table of Contents

    competitive offers by third parties.
     Unlike many of our competitors, we do not require our customers to enter into long-term service contracts. As a result, our customers have the ability to cancel their service at any time without penalty, and we therefore expect our churn rate to be higher than other wireless carriers. In addition, customers could elect to switch to another carrier that has service offerings based on newer network technology. We cannot assure you that our strategies to address customer churn will be successful. If we experience a high rate of wireless customer churn, seek to prevent significant customer churn, or fail to replace lost customers, our revenues could decline and our costs could increase which could have a material adverse effect on our business, financial condition and operating results.
We may not have access to all the funding necessary to build and operate our Auction 66 Markets.
     The proceeds from the sale of the senior notes and our borrowings under our senior secured credit facility did not include the funds necessary to construct, launch and operate our Auction 66 Markets. In addition to the proceeds from our initial public offering, we will need to generate significant excess free cash flow, which is defined as Adjusted EBITDA less capital expenditures, from our operations in our Core and Expansion Markets in order to construct and operate the Auction 66 Markets in the near term or at all. See “Management Discussion and Analysis of Financial Condition and Results of Operations —Liquidity and Capital Resources.” If we are unable to fund the build-out of our Auction 66 Markets with the proceeds from our initial public offering and excess internally generated cash flows, we may be forced to seek additional debt financing or delay our construction. The covenants under our senior secured credit facility and the indenture covering the notes may prevent us from incurring additional debt to fund the construction and operation of the Auction 66 Markets, or may prevent us from securing such funds on suitable terms or in accordance with our preferred construction timetable. Accordingly, we may be required to continue to pay interest on the secured debt and the senior notes for our Auction 66 Market licenses without the ability to generate any revenue from our Auction 66 Markets.
We may not achieve the customer penetration levels in our Core and Expansion Markets that we currently believe are possible with our business model.
     Our ability to achieve the customer penetration levels that we currently believe are possible with our business model in our Core and Expansion Markets is subject to a number of risks, including:
    increased competition from existing competitors or new competitors;
 
    higher than anticipated churn in our Core and Expansion Markets;
 
    our inability to increase our network capacity in areas we currently cover and plan to cover in the Core and Expansion Markets to meet growing customer demand;
 
    our inability to continue to offer products or services which prospective customers want;
 
    our inability to increase the relevant coverage areas in our Core and Expansion Markets in areas that are important to our current and prospective customers;
 
    changes in the demographics of our Core and Expansion Markets; and
 
    adverse changes in the regulatory environment that may limit our ability to grow our customer base.
     If we are unable to achieve the aggregate levels of customer penetration that we currently believe are possible with our business model in our Core and Expansion Markets, our ability to continue to grow our customer base and revenues at the rates we currently expect may be limited. Any failure to achieve the penetration levels we currently believe are possible may have a material adverse impact on our future financial results and operations. Furthermore, any inability to increase our overall level of market penetration in our Core and Expansion Markets, as well as any inability to achieve similar customer penetration levels in other markets we launch in the future, could adversely impact the market price of our stock.

We may be subject to claims of infringement regarding telecommunications technologies that are protected by patents and other intellectual property rights.
     Telecommunications technologies are protected by a wide array of patents and other intellectual property rights. As a result, third parties may assert infringement claims against us from time to time based on our general business operations, the equipment, software or services we use or provide, or the specific operation of our wireless networks. We generally have indemnification agreements with the manufacturers, licensors and suppliers who provide us with the equipment, software and technology that we use in our business to protect us against possible infringement claims, but we cannot guarantee that we will be fully protected against all losses associated with an infringement claim. Moreover, we may be subject to claims that products, software and services provided by different vendors which we combine to offer our services may infringe the rights of third parties and we may not have any indemnification protection from our vendors for these claims. Further, we have been, and may be, subject to further claims that certain business processes we use may infringe the rights of third parties, and we may have no indemnification rights from any of our vendors or suppliers. Whether or not an infringement claim is valid or successful, it could adversely affect our business by diverting management’s attention, involving us in costly and time-consuming litigation, requiring us to enter into royalty or licensing agreements (which may not be available on acceptable terms, or at all), require us to pay royalties for prior periods, or requiring us to redesign our business operations, processes or systems to avoid claims of infringement. If a claim is found to be valid or if we cannot successfully negotiate a required royalty or license agreement, it could disrupt our business, prevent us from offering certain services and cause us to incur losses of customers or revenues, any or all of which could be material and could adversely affect our business, financial performance, operating results and the market price of our stock.
The wireless industry is experiencing rapid technological change, and we may lose customers if we fail to keep up with these changes.
     The wireless telecommunications industry is experiencing significant technological change. Our continued success will depend, in part, on our ability to anticipate or adapt to technological changes and to offer, on a timely basis, services that meet customer demands. We cannot assure you that we will obtain access to new technology on a timely basis, on satisfactory terms, or that we will have adequate spectrum to offer new services or implement new technologies. This could have a material adverse effect on our business, financial condition and operating results. For us to keep pace with these technological changes and remain competitive, we must continue to make significant capital expenditures to our networks and to acquire additional spectrum. Customer acceptance of the services that we offer will continually be affected by technology-based differences in our product and service offerings and those offered by our competitors.
     The wireless telecommunications industry has been, and we believe will continue to be, characterized by several trends, including the following:
    rapid development and introduction of new technologies, products, and services, such as VoIP, push-to-talk services, or push-to-talk, location based services, such as global positioning satellite, or GPS, mapping technology and high speed data services, including streaming video, mobile gaming, video conferencing and other applications;
 
    substantial regulatory change due to the continuing implementation of the Telecommunications Act of 1996, which amended the Communications Act, and included changes designed to stimulate competition for both local and long distance telecommunications services and continued allocation of spectrum for, and relaxation of existing rules to allow existing licensees to offer, wireless services competitive with our services;
 
    increased competition within established metropolitan areas from current and new entrants that may provide competing or alternative services;
 
    an increase in mergers and strategic alliances that allow one telecommunications provider greater access to capital or resources or to offer increased services, access to wider geographic territory, or attractive bundles of services; and
 
    the blurring of traditional dividing lines between, and the bundling of, different services, such as local telephone, long distance, wireless, video, data and Internet services. For example, several

32


Table of Contents

      carriers appear to be positioning themselves to offer a “quadruple play” of services which includes telephone service, Internet access, video service and wireless service.
     We expect competition to intensify as a result of new competitors, allocation of additional spectrum and relaxation of existing policies, and the development of new technologies, products and services. For instance, we currently do not offer certain of the high speed data applications offered by our competitors. In addition, push-to-talk has become popular as it allows subscribers to save time on dialing or connecting to a network and some of the companies that compete with us in our wireless markets offer push-to-talk. We do not offer our customers a push-to-talk service. As demand for this service continues to grow, and if we do not offer these technologies, we may have difficulty attracting and retaining subscribers, which will have an adverse effect on our business. In addition, other service providers have announced plans to develop a WiFi or WiMax enabled handset. Such a handset would permit subscribers to communicate using voice and data services with their handset using VoIP technology in any area equipped with a wireless Internet connection, or hot spot, potentially allowing more carriers to offer larger bundles of minutes while retaining low prices and the ability to offer attractive roaming rates. The number of hot spots in the U.S. is growing rapidly, with some major cities and urban areas being covered entirely. The availability of VoIP or another alternative technology to our competitor’s subscribers could increase their ability to offer competing rate plans, which would have an adverse effect on our ability to attract and retain customers.
We and Royal Street may incur significant costs in our build-out and launch of new markets and we may incur operating losses in those markets for an undetermined period of time.
     We and Royal Street have invested and expect to continue to invest a significant amount of capital to build systems that will adequately cover our Expansion Markets, and we and Royal Street will incur operating losses in each of these markets for an undetermined period of time. We also anticipate having to spend and invest a significant amount of capital to build systems and operate networks in the Auction 66 Markets.
Our and Royal Street’s network capacities in our existing and new markets may be insufficient to meet customer demand or to offer new services that our competitors may be able to offer.
     We and Royal Street have licenses for only 10 MHz of spectrum in certain of our markets, which is significantly less than most of the wireless carriers with whom we and Royal Street compete. This limited spectrum may require Royal Street and us to secure more cell sites to provide equivalent service (including data services based on EV-DO technology), spend greater capital compared to Royal Street’s and our competitors, to deploy more expensive network equipment, such as six-sector antennas and EV-DO Revision A with VoIP, sooner than our competitors, or make us more dependent on improvements in handsets, such as EVRC-B or 4G capable handsets. Royal Street’s and our limited spectrum may also limit Royal Street’s and our ability to support our growth plans without additional technology improvements and/or spectrum, and may make Royal Street and us more reliant on technology advances than our competitors. There is no guarantee we and Royal Street can secure adequate tower sites or additional spectrum, or that expected technology improvements will be available to support Royal Street’s and our business requirements or that the cost of such technology improvements will allow Royal Street and us to remain competitive with other carriers. Competitive carriers in these markets also may take steps prior to Royal Street and us launching service to try to attract Royal Street’s and our target customers. There also is no guarantee that the operations in the Royal Street metropolitan areas, which are based on a wholesale model, will be profitable or successful. Most national wireless carriers have greater spectrum capacity than we do that can be used to support third generation, or 3G, and fourth generation, or 4G, services. These national wireless carriers are currently investing substantial sums of capital to deploy the necessary capital equipment to deliver 3G enhanced services. We and Royal Street have access to less spectrum than certain major competitive carriers in most of our and Royal Street’s markets. Our limited spectrum may make it difficult for us and Royal Street to simultaneously support our voice services and 3G/4G services. In addition, we and Royal Street may have to invest additional capital and/or acquire additional spectrum to support the delivery of 3G/4G services. There is no guarantee that we or Royal Street will be able to provide 3G/4G services on existing licensed spectrum, or will have access to either the spectrum or capital, necessary to provide competitive 3G/4G services in our metropolitan areas, or that our vendors will provide the necessary equipment and software in a timely manner. Moreover, Royal Street’s and our deployment of 3G/4G services requires technology improvements which may not occur or may be too costly for Royal Street and us to compete.

We are dependent on certain network technology improvements which may not occur, or may be materially delayed.
     The adequacy of our spectrum to serve our customers in markets where we have access to only 10 MHz of spectrum is dependent upon certain recent and ongoing technology improvements, such as EV-DO Revision A with VoIP, 4G vocoders, and intelligent antennas. Further, there can be no assurance that (1) the additional technology improvements will be developed by our existing infrastructure provider, (2) such improvements will be delivered when needed, (3) the prices for such improvements will be cost-effective, or (4) the technology improvements will deliver our projected network efficiency improvements. If projected or anticipated technology improvements are not achieved, or are not achieved in the timeframes we need such improvements, we and Royal Street may not have adequate spectrum in certain metropolitan areas, which may limit our ability to grow our customer base, may inhibit our ability to achieve additional economies of scale, may limit our ability to offer new services offered by our competitors, may require us to spend considerably more capital and incur more operating expenses than our competitors with more spectrum, and may force us to purchase additional spectrum at a potentially material cost. If our network infrastructure vendor does not supply such improvements or materially delays the delivery of such improvements and other network equipment manufacturers are able to develop such technology, we may be at a material competitive disadvantage to our competitors and we may be required to change network infrastructure vendors, the cost of which could be material.
We may be unable to acquire additional spectrum in the future at a reasonable cost.
     Because we offer unlimited calling services for a fixed fee, our customers tend, on average, to use our services more than the customers of other wireless carriers. We believe that the average amount of use our customers generate may continue to rise. We intend to meet this demand by utilizing spectrum-efficient state-of-the-art technologies, such as six-sector cell site technology, EV-DO Revision A with VoIP, 4G vocoders and intelligent antennas. Nevertheless, in the future we may need to acquire additional spectrum in order to maintain our grade of service and to meet increasing customer demands. However, we cannot be sure that additional spectrum will be made available by the FCC for commercial uses on a timely basis or that we will be able to acquire additional spectrum at a reasonable cost. For example, there have been recent calls for reallocating spectrum previously slated for commercial mobile uses to public safety uses in order to enable first responders to establish an interoperable nationwide broadband network. If the additional spectrum is unavailable when needed or unavailable at a reasonable cost, we could lose customers or revenues, which could be material, and our ability to grow our customer base may be materially adversely affected.
Substantially all of our network infrastructure equipment is manufactured or provided by a single infrastructure vendor and any failure by that vendor could result in a material adverse effect on us.
     We have entered into a general purchase agreement with an initial term of three years, effective as of June 6, 2005, with Lucent Technologies, Inc., or Lucent, now known as Alcatel Lucent, as our network infrastructure supplier of PCS CDMA system products and services, including without limitation, wireless base stations, switches, power, cable and transmission equipment and services. The agreement does not cover the spectrum we recently acquired in Auction 66. The agreement provides for both exclusive and non-exclusive pricing for PCS CDMA products and the agreement may be renewed at our option on an annual basis for three additional years after its initial three-year term concludes. Substantially all of our PCS network infrastructure equipment is manufactured or provided by Alcatel Lucent. A substantial portion of the equipment manufactured or provided by Alcatel Lucent is proprietary, which means that equipment and software from other manufacturers may not work with Alcatel Lucent’s equipment and software, or may require the expenditure of additional capital, which may be material. If Alcatel Lucent ceases to develop, or substantially delays development of, new products or support existing equipment and software, we may be required to spend significant amounts of money to replace such equipment and software, may not be able to offer new products or service, and may not be able to compete effectively in our markets. If we fail to continue purchasing our PCS CDMA products exclusively from Alcatel Lucent, we may have to pay certain liquidated damages based on the difference in prices between exclusive and non-exclusive prices, which may be material to us.
Our network infrastructure vendor has merged, which could have a material adverse effect on us.
     Lucent announced on April 2, 2006 that it had entered into a definitive merger agreement with Alcatel, and the shareholders of each company approved the merger. Alcatel and Lucent announced on November 30, 2006 the

34


Table of Contents

completion of the merger and the companies began doing business on December 1, 2006 as “Alcatel Lucent.” There can be no assurance that the combined entity will continue to produce and support the products and services that we currently purchase from Alcatel Lucent. In addition, the combined entity may delay or cease developing or supplying products or services necessary to our business. If Alcatel Lucent delays or ceases to produce products or services necessary to our business and we are unable to secure replacement products and services on reasonable terms and conditions, our business could be materially adversely affected.
Our network infrastructure vendor may change where it manufactures equipment necessary for our network which could have a material adverse effect on us.
     As a result of its ongoing operations, Alcatel Lucent may move the manufacturing of some of its products from its existing facilities in one country to another manufacturing facility located in another country and that process may accelerate with the completion of its merger. To the extent that products are manufactured outside the current facilities, we may experience delays in receiving products from Alcatel Lucent and the quality of the products we receive may suffer. These delays and quality problems could cause us to experience problems in increasing capacity of our existing systems, expanding our service areas, and the construction of new markets. If these delays or quality problems occur, they could have a material adverse effect on our ability to meet our business plan and our business operations and finances may be materially adversely affected.
No equipment or handsets are currently available for the AWS spectrum and such equipment or handsets may not be developed in a timely manner.
     The AWS spectrum requires modified or new equipment and handsets which are not currently available. We do not manufacture or develop our own equipment or handsets and are dependent on third party manufacturers to design, develop and manufacture such equipment. If equipment or handsets are not available when we need them, we may not be able to develop the Auction 66 Markets. We may, therefore, be forced to pay interest on our indebtedness which we used to fund the purchase of the licenses in Auction 66, without realizing any revenues from our Auction 66 Markets.
If we are unable to manage our planned growth effectively, our costs could increase and our level of service could be adversely affected.
     We have experienced rapid growth and development in a relatively short period of time and expect to continue to experience substantial growth in the future. The management of rapid growth will require, among other things, continued development of our financial and management controls and management information systems. Historically, we have failed to adequately implement financial controls and management systems.
     We publicly acknowledged deficiencies in our financial reporting as early as August 2004, and controls and systems designed to address these deficiencies are not yet fully implemented. The costs of implementing these controls and systems will affect the near-term financial results of the business and the lack of these controls and systems may materially adversely affect our ability to access the capital markets.
     Our expected growth also will require stringent control of costs, diligent management of our network infrastructure and our growth, increased capital requirements, increased costs associated with marketing activities, the ability to attract and retain qualified management, technical and sales personnel and the training and management of new personnel. Our growth will challenge the capacity and abilities of existing employees and future employees at all levels of our business. Failure to successfully manage our expected growth and development could have a material adverse effect on our business, increase our costs and adversely affect our level of service. Additionally, the costs of acquiring new customers could adversely affect our near-term profitability.
We have identified material weaknesses in our internal control over financial reporting in the past. We will incur significant time and expense enhancing, documenting, testing and certifying our internal control over financial reporting and our business may be adversely affected if we have other material weaknesses or significant deficiencies in our internal control over financial reporting in the future.
     In connection with the preparation of our quarterly financial statements for the three months ended June 30, 2004, we determined that previously disclosed financial statements for the three months ended March 31, 2004 understated service revenues and net income. Additionally, in connection with their evaluation of our disclosure

35


Table of Contents

controls and procedures with respect to the filing in May 2006 of our Annual Report on Form 10-K for the year ended December 31, 2004, our chief executive officer and chief financial officer concluded that certain material weaknesses in our internal controls over financial reporting existed as of December 31, 2004. The material weaknesses related to deficiencies in our information technology and accounting control environments, insufficient “tone at the top,” deficiencies in our accounting for income taxes, and a lack of automation in our revenue reporting process. In connection with their review of our material weaknesses, our management and audit committee concluded that our previously reported consolidated financial statements for the years ended December 31, 2002 and 2003 should be restated to correct accounting errors resulting from these material weaknesses.
     We have identified, developed and implemented a number of measures to strengthen our internal control over financial reporting and address the material weaknesses that we identified in 2004. Although there were no reported material weaknesses in our internal controls over financial reporting as of December 31, 2006, our management did identify significant deficiencies relating to the accrual of equipment and services and the accounting for distributed antenna system agreements. There can be no assurance that we will not have significant deficiencies in the future or that such conditions will not rise to the level of a material weakness. The existence of one or more material weaknesses or significant deficiencies could result in errors in our financial statements or delays in the filing of our periodic reports required by the SEC. Any failure by us to timely file our periodic reports could result in a breach of the indenture covering the senior notes and our secured credit facility, potentially accelerating payment under both agreements. We may not have the ability to pay, or borrow any amounts necessary to pay, any accelerated payment due under the secured credit facility or the indenture covering the senior notes. We may also incur substantial costs and resources to rectify any internal control deficiencies.
     As a public company we will incur significant legal, accounting, insurance and other expenses. The Sarbanes-Oxley Act of 2002, as well as compliance with other SEC and exchange listing rules, will increase our legal and financial compliance costs and make some activities more time-consuming and costly. Furthermore, as a public company, SEC rules require that our chief executive officer and chief financial officer periodically certify the existence and effectiveness of our internal control over financial reporting. Our independent registered public accounting firm will be required, beginning with our Annual Report on Form 10-K for our fiscal year ending on December 31, 2007, to attest to our assessment of our internal control over financial reporting.
     During the course of our testing, we may identify deficiencies that would have to be remediated to satisfy the SEC rules for certification of our internal control over financial reporting. As a consequence, we may have to disclose in periodic reports we file with the SEC significant deficiencies or material weaknesses in our system of internal controls. The existence of a material weakness would preclude management from concluding that our internal control over financial reporting is effective, and would preclude our independent auditors from issuing an unqualified opinion that our internal control over financial reporting is effective. If we cannot produce reliable financial reports, we may be in breach of the indenture covering the senior notes and our secured credit facility, potentially accelerating payment under both agreements. In addition, disclosures of this type in our SEC reports could cause investors to lose confidence in our financial reporting and may negatively affect the trading price of our common stock. Moreover, effective internal controls are necessary to produce reliable financial reports and to prevent fraud. If we have deficiencies in our disclosure controls and procedures or internal control over financial reporting it may negatively impact our business, results of operations and reputation.
Because we may have issued stock options and shares of common stock in violation of federal and state securities laws and some of our stockholders and option holders may have a right of rescission, we intend to make a rescission offer to certain holders of shares of our common stock and options to purchase shares of our common stock.
     Certain options to purchase our common stock granted since January 2004 and certain shares issued upon exercise of options granted during this period may not have been exempt from the registration and qualification requirements of the Securities Act of 1933 or under the securities laws of a few states. As of December 31, 2006, we granted to employees and former employees options to purchase approximately 2,148,000 shares of our common stock, of which approximately 1,959,000 options remain outstanding with a weighted average exercise price per option of $6.28. We issued these options and shares of common stock in reliance on Rule 701 under the Securities Act of 1933. However, we may not have been entitled to rely on Rule 701 because (1) during certain periods we exceeded certain thresholds in the rule and may not have delivered to our option holders the financial and other information required to be delivered by Rule 701; and (2) during certain periods in 2004 and 2006 we were subject to, or should have been subject to, the periodic reporting requirements under the Securities Exchange Act of 1934.

36


Table of Contents

As a result, certain holders of options and shares acquired from us may have a right to require us to repurchase those securities if we are found to be in violation of federal or state securities laws.
     In order to address these issues, we intend to make a rescission offer to the holders of options to purchase approximately 1,959,000 shares of our common stock as soon as practicable after the completion of our initial public offering. We will be making this offer to approximately 525 of our current and former employees. If the rescission offer is accepted by all persons to whom it is made, we could be required to make aggregate payments of up to approximately $2.6 million. This amount reflects a purchase price equal to the price paid by the holder for each share of common stock that is the subject of the rescission offer and a purchase price equal to 20% of the aggregate exercise price for each option that is the subject of the rescission offer. It is possible that an option holder could argue that the purchase price for the options does not represent an adequate remedy for the issuance of the option in violation of applicable securities laws, and a court may find that we are required to pay a greater amount for the options.
     There can be no assurance that the SEC or state regulatory bodies will not take the position that any rescission offers should extend to all holders of options or stock acquired upon exercise of options granted during the relevant periods. The Securities Act of 1933 also does not provide that a rescission offer will extinguish a holder’s right to rescind the grant of an option or the issuance of shares that were not registered or exempt from the registration requirements under the Securities Act of 1933. Consequently, should any recipients of our rescission offer reject the offer, expressly or impliedly, we may remain liable under the Securities Act of 1933 for the purchase price of the options and shares that are subject to the rescission offer.
We failed to register our stock options under the Securities Exchange Act of 1934 and, as a result, we may face potential claims under federal and state securities laws.
     As of December 31, 2005, options granted under our 1995 option plan and our 2004 equity incentive plan were held by more than 500 holders. As a result, we were required to file a registration statement registering the stock options pursuant to Section 12(g) of the Securities Exchange Act of 1934 no later than April 30, 2006. We failed to file a registration statement within the required time period.
     If we had filed a registration statement pursuant to Section 12(g) as required, we would have become subject to the periodic reporting requirements of Section 13 of the Securities Exchange Act of 1934 upon the effectiveness of that registration statement. We have not filed any periodic reports, including quarterly reports on Form 10-Q and periodic reports on Form 8-K during the period since April 30, 2006, which is the latest date upon which we were required to file a registration statement.
     Our failure to file the periodic reports we would have been required to file had we registered our common stock pursuant to Section 12(g) could give rise to potential claims by present or former stockholders based on the theory that such holders were harmed by the absence of such public reports. In addition to any claims by present or former stockholders, we could be subject to administrative and/or civil actions by the SEC. If any such claim or action is asserted, we could incur significant expenses and divert management’s attention in defending them.
Our failure to timely file a registration statement under the Securities Exchange Act of 1934, may mean that we may not be able to timely meet our periodic reporting requirements as a public company.
     As a publicly-traded company, we are now required to file periodic reports with the SEC containing our financial statements within a specified period following the completion of quarterly and annual periods. In 2006, we failed to file a registration statement under the Securities Exchange Act of 1934 within the time period required by Section 12(g) of such act as a result of our failure to have in place procedures to inform us that we were required to file a registration statement. Our failure to timely file that registration statement may mean that we may not have all of the controls and procedures in place to ensure compliance with all of the rules and requirements applicable to public companies. Any failure by us to file our periodic reports with the SEC in a timely manner could harm our reputation and reduce the trading price of our common stock.
A significant portion of our revenue is derived from geographic areas susceptible to natural and other disasters.
     Our markets in California, Texas and Florida contribute a substantial amount of revenue, operating cash flows, and net income to our operations. These same states, however, have a history of natural disasters which may

37


Table of Contents

adversely affect our operations in those states. The severity and frequency of certain of these natural disasters, such as hurricanes, are projected to increase over the next several years. In addition, the major metropolitan areas in which we operate, or plan to operate, could be the target of terrorist attacks. These events may cause our networks to cease operating for a substantial period of time while we reconstruct them and our competitors may be less affected by such natural disasters or terrorist attacks. If our networks cease operating for any substantial period of time, we may lose revenue and customers, and may have difficulty attracting new customers in the future, which could materially adversely affect our operations. Although we have business interruption insurance which we believe is adequate, we cannot provide any assurance that the insurance will cover all losses we may experience as a result of a natural disaster or terrorist attack or that the insurance carrier will be solvent.
Our substantial indebtedness could adversely affect our financial health.
     We have now, and will continue to have, a significant amount of debt. As of December 31, 2006, we had $2.6 billion of outstanding indebtedness under the senior secured credit facility and the senior notes. Our substantial amount of debt could have important material adverse consequences to us. For example, it could:
    increase our vulnerability to general adverse economic and industry conditions;
 
    require us to dedicate a substantial portion of our cash flow from operations to make interest and principal payments on our debt, limiting the availability of our cash flow to fund future capital expenditures for existing or new markets, working capital and other general corporate requirements;
 
    limit our flexibility in planning for, or reacting to, changes in our business and the telecommunications industry;
 
    limit our ability to purchase additional spectrum, develop new metropolitan areas in the future or fund growth in our metropolitan areas;
 
    place us at a competitive disadvantage compared with competitors that have less debt; and
 
    limit our ability to borrow additional funds, even when necessary to maintain adequate liquidity.
     In addition, a substantial portion of our debt, including borrowings under our senior secured credit facility, bears interest at variable rates. Although we have entered into a transaction to hedge some of our interest rate risk, if market interest rates increase, variable-rate debt will create higher debt service requirements, which could adversely affect our cash flow. While we have and may in the future enter into agreements limiting our exposure to higher interest rates, any such agreements may not offer complete protection from this risk and any portions not subject to such agreements would have full exposure to higher interest rates. We estimate the interest expense and principal repayments on our debt for the 12 months ending December 31, 2007 to be approximately $228.1 million.
Despite current indebtedness levels, we will be able to incur substantially more debt. This could further exacerbate the risks associated with our leverage.
     We will be able to incur additional debt in the future despite our current level of indebtedness. The terms of the senior secured credit facility and the indenture governing the senior notes will allow us to incur substantial amounts of additional debt, subject to certain limitations. There are no restrictions on our or any of our future unrestricted subsidiaries’ ability to incur additional indebtedness. If new debt is added to our current debt levels, the related risks we could face would be magnified.
To service our debt, we will require a significant amount of cash, which may not be available to us.
     Our ability to make payments on, or repay or refinance, our debt and to fund planned capital expenditures and operating losses associated with the Expansion Markets and the Auction 66 Markets, will depend largely upon receipt of proceeds from our initial public offering and our future operating performance. Our future performance is subject to certain general economic, financial, competitive, legislative, regulatory and other factors that are beyond our control. In addition, our ability to borrow funds in the future to make payments on our debt will depend on the satisfaction of the covenants in our senior secured credit facility, the indenture covering the senior notes and our

38


Table of Contents

other debt agreements and other agreements we may enter into in the future. Specifically, we will need to maintain specified financial ratios and satisfy financial condition tests. We cannot assure you that our business will generate sufficient cash flow from operations or that future borrowings will be available to us under our senior secured credit facility or from other sources in an amount sufficient to enable us to pay interest or principal on our debt, including the senior notes, or to fund our other liquidity needs.
     The terms of our debt place restrictions on certain of our subsidiaries which may limit our operating flexibility.
     The indenture governing the senior notes and the senior secured credit facility impose material operating and financial restrictions on MetroPCS Wireless and certain of its subsidiaries. These restrictions, subject in certain cases to ordinary course of business and other exceptions, may limit MetroPCS Wireless’ and our ability to engage in some transactions, including the following:
    paying dividends, redeeming capital stock or making other restricted payments or investments;
 
    paying interest on any additional indebtedness incurred;
 
    selling or buying assets, properties or licenses;
 
    developing assets, properties or licenses which we have or in the future may procure;
 
    creating liens on assets;
 
    participating in future FCC auctions of spectrum;
 
    merging, consolidating or disposing of assets;
 
    entering into transactions with affiliates; and
 
    permitting subsidiaries (which does not include Royal Street) to pay dividends or make other payments.
     In addition, although MetroPCS Communications and its unrestricted subsidiaries have the ability to incur new indebtedness, the indenture governing the senior notes and the senior secured credit facility impose restrictions on the ability of MetroPCS Wireless and some of our other subsidiaries to incur additional debt. Because substantially all of our current operations are conducted through MetroPCS Wireless and the other subsidiaries that are subject to these restrictions, our operating flexibility may be limited.
     Under the senior secured credit facility, MetroPCS Wireless is also subject to financial maintenance covenants with respect to its senior secured leverage and in certain circumstances total maximum consolidated leverage and certain minimum fixed charge coverage ratios.
     These restrictions could limit MetroPCS Wireless’ and our ability to obtain debt financing, repurchase stock, refinance or pay principal on our outstanding debt, complete acquisitions for cash or debt or react to changes in our operating environment. Any future debt that we incur may contain similar or more restrictive covenants.
Our success depends on our ability to attract and retain qualified management and other personnel.
     Our business is managed by a small number of key executive officers. The loss of one or more of these persons could disrupt our ability to react quickly to business developments and changes in market conditions, which could harm our financial results. As of April 1, 2007, none of our key executives has an employment contract, so any of our key executive officers may leave at any time subject to forfeiture of any unpaid performance awards and any unvested stock options. In addition, upon any change in control, all unvested stock options will vest which may make it difficult for anyone to acquire us. We believe that our future success will also depend in large part on our continued ability to attract and retain highly qualified executive, technical and management personnel. We believe competition for highly qualified management, technical and sales personnel is intense, and there can be no assurance that we will retain our key management, technical and sales employees or that we will be successful in attracting,

39


Table of Contents

assimilating or retaining other highly qualified management, technical and sales personnel in the future sufficient to support our continued growth. We have occasionally experienced difficulty in recruiting qualified personnel and there can be no assurance that we will not experience such difficulties in the future. Our inability to attract or retain highly qualified executive, technical and management personnel could materially and adversely affect our business operations and financial performance.
We rely on third-party suppliers to provide our customers and us with equipment, software and services that are integral to our business, and any significant disruption in our relationship with these vendors could increase our cost and affect our operating efficiencies.
     We have entered into agreements with third-party suppliers to provide equipment and software for our network and services required for our operations, such as customer care and billing and payment processing. Sophisticated information and billing systems are vital to our ability to monitor and control costs, bill customers, process customer orders, provide customer service and achieve operating efficiencies. We currently rely on internal systems and third-party vendors to provide all of our information and processing systems. Some of our billing, customer service and management information systems have been developed by third-parties and may not perform as anticipated. If these suppliers experience interruptions or other problems delivering these products or services on a timely basis or at all, it may cause us to have difficulty providing services to or billing our customers, developing and deploying new services and/or upgrading, maintaining, improving our networks, or generating accurate or timely financial reports and information. If alternative suppliers and vendors become necessary, we may not be able to obtain satisfactory and timely replacement services on economically attractive terms, or at all. Some of these agreements may be terminated upon relatively short notice. The loss, termination or expiration of these contracts or our inability to renew them or negotiate contracts with other providers at comparable rates could harm our business. Our reliance on others to provide essential services on our behalf also gives us less control over the efficiency, timeliness and quality of these services. In addition, our plans for developing and implementing our information and billing systems rely to some extent on the design, development and delivery of products and services by third-party vendors. Our right to use these systems is dependent on license agreements with third-party vendors. Since we rely on third-party vendors to provide some of these services, any switch or disruption by our vendors could be costly and affect operating efficiencies.
If we lose the right to install our equipment on wireless cell sites, or are unable to renew expiring leases for wireless cell sites on favorable terms or at all, our business and operating results could be adversely impacted.
     Our base stations are installed on leased cell site facilities. A significant portion of these cell sites are leased from a small number of large cell site companies under master agreements governing the general terms of our use of that company’s cell sites. If a master agreement with one of these cell site companies were to terminate, the cell site company were to experience severe financial difficulties or file for bankruptcy or if one of these cell site companies were unable to support our use of its cell sites, we would have to find new sites or rebuild the affected portion of our network. In addition, the concentration of our cell site leases with a limited number of cell site companies could adversely affect our operating results and financial condition if we are unable to renew our expiring leases with these cell site companies either on terms comparable to those we have today or at all.
     In addition, the tower industry has continued to consolidate. If any of the companies from which we lease towers or distributed antenna systems, or DAS systems, were to consolidate with other tower or DAS systems companies, they may have the ability to raise prices which could materially affect our profitability. If any of the cell site leasing companies or DAS system providers with which we do business were to experience severe financial difficulties, or file for bankruptcy protection, our ability to use cell sites leased from that company could be adversely affected. If a material number of cell sites were no longer available for our use, our financial condition and operating results could be adversely affected.
We may be unable to obtain the roaming and other services we need from other carriers to remain competitive.
     Many of our competitors have regional or national networks which enable them to offer automatic roaming and long distance telephone services to their subscribers at a lower cost than we can offer. We do not have a national network, and we must pay fees to other carriers who provide roaming services and who carry long distance calls made by our subscribers. We currently have roaming agreements with several other carriers which allow our customers to roam on those carriers’ network. The roaming agreements, however, do not cover all geographic areas where our customers may seek service when they travel, generally cover voice but not data services, and at least one

40


Table of Contents

such agreement may be terminated on relatively short notice. In addition, we believe the rates charged by the carriers to us in some instances are higher than the rates they charge to certain other roaming partners. The FCC recently initiated a Notice of Proposed Rulemaking seeking comments on whether automatic roaming services are considered common carrier services, whether carriers have an obligation to offer automatic roaming services to other carriers, whether carriers have an obligation to provide non-voice automatic roaming services, and what rates a carrier may charge for roaming services. We are unable to predict with any certainty the likely outcome of this proceeding. The FCC previously has initiated roaming proceedings to address similar issues but repeatedly has failed to resolve these issues. Our current and future customers may desire that we offer automatic roaming services when they travel outside the areas we serve which we may be unable to obtain or provide cost effectively. If we are unable to obtain roaming agreements at reasonable rates, then we may be unable to effectively compete and may lose customers and revenues.
A recent ruling from the Copyright Office of the Library of Congress may have an adverse effect on our distribution strategy.
     The Copyright Office of the Library of Congress, or the Copyright Office, recently released final rules on its triennial review of the exemptions to certain provisions of the Digital Millennium Copyright Act, or DMCA. A section of the DMCA prohibits anyone other than a copyright owner from circumventing technological measures employed to protect a copyrighted work, or access control. In addition, the DMCA provides that the Copyright Office may exempt certain activities which otherwise might be prohibited by that section of the DMCA for a period of three years when users are (or in the next three years are likely to be) adversely affected by the prohibition on their ability to make noninfringing uses of a class of copyrighted work. Many carriers, including us, routinely place software locks on wireless handsets, which prevent a customer from using a wireless handset sold by one carrier on another carrier’s system. In its triennial review, the Copyright Office determined that these software locks on wireless handsets are access controls which adversely affect the ability of consumers to make noninfringing use of the software on their wireless handsets. As a result, the Copyright Office found that a person could circumvent such software locks and other firmware that enable wireless handsets to connect to a wireless telephone network when such circumvention is accomplished for the sole purpose of lawfully connecting the wireless handset to another wireless telephone network. A wireless carrier has filed suit in the United States District Court in Florida to reverse the Copyright Office’s decision. This exemption is effective from November 27, 2006 through October 27, 2009 unless extended by the Copyright Office.
     This ruling, if upheld, could allow our customers to use their wireless handsets on networks of other carriers. This ruling may also allow our customers who are dissatisfied with our service to utilize the services of our competitors without having to purchase a new handset. The ability of our customers to leave our service and use their wireless handsets on other carriers’ networks may have an adverse material impact on our business. In addition, since we provide a subsidy for handsets to our distribution partners that is incurred in advance, we may experience higher distribution costs resulting from wireless handsets not being activated or maintained on our network, which costs may be material.
We may incur higher than anticipated intercarrier compensation costs, which could increase our costs and reduce our profit margin.
     When our customers use our service to call customers of other carriers, we generally are required to pay the carrier that serves the called party and any intermediary or transit carrier for the use of their network. Similarly, when a customer of another carrier calls one of our customers, that carrier generally is required to pay us for the use of our network. While we generally have been successful in negotiating agreements with other carriers that establish acceptable compensation arrangements, some carriers have claimed a right to unilaterally impose charges on us that we consider to be unreasonably high. The FCC has determined that certain unilateral termination charges imposed prior to April 2005 may be appropriate. We have requested clarification of this order. We cannot assure you that the FCC will rule in our favor. An adverse ruling or FCC inaction could result in some carriers successfully collecting such fees from us, which could increase our costs and affect our financial performance. In the meantime, certain carriers are threatening to pursue or have initiated claims against us for termination payments and the likely outcome of these claims is uncertain. A finding by the FCC that we are liable for additional terminating compensation payments could subject us to additional claims by other carriers. In addition, certain transit carriers have taken the position that they can charge “market” rates for transit services, which may in some instances be significantly higher than our current rates. We may be obligated to pay these higher rates and/or purchase services from others or engage in direct connection, which may result in higher costs which could materially affect our costs and financial results.

Concerns about whether wireless telephones pose health and safety risks may lead to the adoption of new regulations, to lawsuits and to a decrease in demand for our services, which could increase our costs and reduce our revenues.
     Media reports and some studies have suggested that radio frequency emissions from wireless handsets are linked to various health concerns, including cancer, or interfere with various electronic medical devices, including hearing aids and pacemakers. Additional studies have been undertaken to determine whether the suggestions from those reports and studies are accurate. In addition, lawsuits have been filed against other participants in the wireless industry alleging various adverse health consequences as a result of wireless phone usage. While many of these lawsuits have been dismissed on various grounds, including a lack of scientific evidence linking wireless handsets with such adverse health consequences, future lawsuits could be filed based on new evidence or in different jurisdictions. If any such suits do succeed, or if plaintiffs are successful in negotiating settlements, it is likely additional suits would be filed. Additionally, certain states in which we offer or may offer service have passed or may pass legislation seeking to require that all wireless telephones include an earpiece that would enable the use of wireless telephones without holding them against the user’s head. While it is not possible to predict whether any additional states in which we conduct business will pass similar legislation, such legislation could increase the cost of our wireless handsets and other operating expenses.
     If consumers’ health concerns over radio frequency emissions increase, consumers may be discouraged from using wireless handsets, and regulators may impose restrictions or increased requirements on the location and operation of cell sites or the use or design of wireless telephones. Such new restrictions or requirements could expose wireless providers to further litigation, which, even if not successful, may be costly to defend, or could increase our cost of handsets and equipment. In addition, compliance with such new requirements, and the associated costs, could adversely affect our business. The actual or perceived risk of radio frequency emissions could also adversely affect us through a reduction in customers or a reduction in the availability of financing in the future. In addition to health concerns, safety concerns have been raised with respect to the use of wireless handsets while driving. Certain states and municipalities in which we provide service or plan to provide service have passed laws prohibiting the use of wireless phones while driving or requiring the use of wireless headsets. If additional state and local governments in areas where we conduct business adopt regulations restricting the use of wireless handsets while driving, we could have reduced demand for our services.
A system failure could cause delays or interruptions of service, which could cause us to lose customers.
     To be successful, we must provide our customers reliable service. Some of the risks to our network and infrastructure which may prevent us from providing reliable service include:
    physical damage to outside plant facilities;
 
    power surges or outages;
 
    equipment failure;
 
    vendor or supplier failures or delays;
 
    software defects;
 
    human error;
 
    disruptions beyond our control, including disruptions caused by terrorist activities, theft, or natural disasters; and
 
    failures in operational support systems.
     Network disruptions may cause interruptions in service or reduced capacity for customers, either of which could cause us to lose customers and incur expenses. Further, our costs to replace or repair the network may be substantial, thus causing our costs to provide service to increase. We may also experience higher churn as our competitors systems may not experience similar problems.

42


Table of Contents

Unauthorized use of, or interference with, our network could disrupt service and increase our costs.
     We may incur costs associated with the unauthorized use of our network including administrative and capital costs associated with detecting, monitoring and reducing the incidence of fraud. Fraudulent use of our network may impact interconnection and long distance costs, capacity costs, administrative costs, fraud prevention costs and payments to other carriers for fraudulent roaming. Such increased costs could have a material adverse impact on our financial results.
Security breaches related to our physical facilities, computer networks, and informational databases may cause harm to our business and reputation and result in a loss of customers.
     Our physical facilities and information systems may be vulnerable to physical break-ins, computer viruses, theft, attacks by hackers, or similar disruptive problems. If hackers gain improper access to our databases, they may be able to steal, publish, delete or modify confidential personal information concerning our subscribers. In addition, misuse of our customer information could result in more substantial harm perpetrated by third-parties. This could damage our business and reputation and result in a loss of customers.
Risks Related to Legal and Regulatory Matters
We are dependent on our FCC licenses, and our ability to provide service to our customers and generate revenues could be harmed by adverse regulatory action or changes to existing laws or rules.
     The FCC regulates most aspects of our business, including the licensing, construction, modification, operation, use, ownership, control, sale, roaming arrangements and interconnection arrangements of wireless communications systems, as do some state and local regulatory agencies. We can make no assurances that the FCC or the state and local agencies having jurisdiction over our business will not adopt regulations or take other actions that would adversely affect our business by imposing new costs or requiring changes in our current or planned operations, or that the Communications Act, from which the FCC obtains its authority, will not be amended in a manner materially adverse to us.
     Taken together or individually, new or changed regulatory requirements affecting any or all of the wireless, local, and long distance industries may harm our business and restrict the manner in which we operate our business. The enactment of new adverse legislation, regulation or regulatory requirements may slow our growth and have a material adverse effect upon our business, results of operations and financial condition. We cannot assure you that changes in current or future regulations adopted by the FCC or state regulators, or other legislative, administrative or judicial initiatives relating to the communications industry, will not have a material adverse effect on our business, results of operations and financial condition. In addition, pending congressional legislative efforts to reform the Communications Act may cause major industry and regulatory changes that are difficult to predict and which may have material adverse consequences to us.
     Some of our principal assets are our FCC licenses which we use to provide our services. The loss of any of these licenses could have a material adverse effect on our business. Our FCC licenses are subject to revocation if the FCC finds we are not in compliance with its rules or the Communications Act’s requirements. We also could be subject to fines and forfeitures for such non-compliance, which could adversely affect our business. For example, absent a waiver, failure to comply with the FCC’s Enhanced-911, or E-911, requirements, privacy rules, lighting and painting regulations, employment regulations, Customer Proprietary Network Information, or CPNI, protection rules, hearing aid-compatibility rules, number portability requirements, law enforcement cooperation, rate averaging or other existing or new regulatory mandates could subject us to significant penalties or a revocation of our FCC licenses, which could have a material adverse effect on our business, results of operations and financial condition. In addition, a failure to comply with these requirements or the FCC’s construction requirements could result in revocation of the licenses and/or fines and forfeitures, any of which could have an adverse effect on our business.
The structure of the transaction with Royal Street creates several risks because we do not control Royal Street and do not own or control the licenses it holds.
     We have agreements with Royal Street that are intended to allow us to actively participate in the development of the Royal Street licenses and networks, and we have the right to acquire on a wholesale basis 85% of the services provided by the Royal Street systems and to resell these services on a retail basis under our brand in

43


Table of Contents

accordance with applicable laws and regulations. There are, nonetheless, risks inherent in the fact that we do not own or control Royal Street or the Royal Street licenses. C9 Wireless, LLC, or C9, an unaffiliated third party, has the ability to put all or part of its ownership interest in Royal Street Communications to us, but, due to regulatory restrictions, we have no corresponding right to call C9’s ownership interest in Royal Street Communications. We can give no assurance that C9 will exercise its put rights or, if it does, when such exercise may occur. Further, these put rights expire in June 2012. Subject to certain non-controlling investor protections in Royal Street Communication’s limited liability company agreement, C9 also has control over the operations of Royal Street because it has the right to elect three of the five members of Royal Street Communication’s management committee, which has the full power to direct the management of Royal Street. The FCC’s rules also restrict our ability to acquire or control Royal Street licenses during the period that Royal Street must maintain its eligibility as a very small business designated entity, or DE, which is currently through December 2010. Thus, we cannot be certain that the Royal Street licenses will be developed in a manner fully consistent with our business plan or that C9 will act in ways that benefit us.
     Royal Street acquired certain of its PCS licenses as a DE entitled to a 25% discount. As a result, Royal Street received a bidding credit equal to approximately $94 million for its PCS licenses. If Royal Street is found to have lost its status as a DE it would be required to repay the FCC the amount of the bidding credit on a five-year straight-line basis beginning on the grant date of the license. If Royal Street were required to pay this amount, it could have a material adverse effect on us due to our non-controlling 85% limited liability company member interest in Royal Street. In addition, if Royal Street is found to have lost its status as a DE, it could lose some or all of the licenses only available to DEs, which includes most of its licenses in Florida. If Royal Street lost those licenses, it could have a material adverse effect on us because we would lose access to the Orlando metropolitan area and certain portions of northern Florida.
     Certain recent regulatory developments pertaining to the DE program indicate that the FCC plans to be proactive in assuring that DEs abide by the FCC’s control requirements. The FCC has the right to audit the compliance of DEs with FCC rules governing their operations, and there have been recent indications that it intends to exercise that authority. In addition, the Royal Street business plan may become so closely aligned with our business plan that there is a risk the FCC may find Royal Street to have relinquished control over its licenses in violation of FCC requirements. If the FCC were to determine that Royal Street has failed to exercise the requisite control over its licenses, the result could be the loss of closed licenses, which are licenses that the FCC only offered to qualified DEs, the loss of bidding credits, which effectively lowered the purchase price for the open licenses, and fines and forfeitures, which amounts may be material.
     In making the changes to the DE rules, the FCC concluded that certain relationships between a DE licensee and its investors would in the future be deemed impermissible material relationships based on a new FCC view that these relationships, by their very nature, are generally inconsistent with an applicant’s or licensee’s ability to achieve or maintain designated entity eligibility and inconsistent with Congress’ legislative intent. The FCC cited wholesale service arrangements as an example of an impermissible material relationship, but indicated that previously approved arrangements of this nature would be allowed to continue. While the FCC has grandfathered the existing arrangements between Royal Street and us, there can be no assurance that any changes that may be required of those arrangements in the future will not cause the FCC to determine that the changes would trigger the loss of DE eligibility for Royal Street and require the reimbursement of the bidding credits received by Royal Street and loss of any licenses covering geographic areas which are not sufficiently constructed that were available initially only to DEs. Further, the FCC has opened a Notice of Further Proposed Rulemaking seeking to determine what additional changes, if any, may be required or appropriate to its DE program. There can be no assurance that these changes will not be applied to the current arrangements between Royal Street and us. Any of these results could be materially adverse to our business.
We may not be able to continue to offer our services if the FCC does not renew our licenses when they expire.
     Our current PCS licenses began to expire in January 2007. We have filed applications to renew our PCS licenses for additional ten-year periods by filing renewal applications with the FCC as soon as the filing windows were opened. A number of the renewal applications have been granted, including all of the licenses that expired in January 2007. The remainder of the applications are currently pending or the filing window has not yet opened. Renewal applications are subject to FCC review and potentially public comment to ensure that licensees meet their licensing requirements and comply with other applicable FCC mandates. If we fail to file for renewal of any particular license at the appropriate time or fail to meet any regulatory requirements for renewal, including

44


Table of Contents

construction and substantial service requirements, we could be denied a license renewal and, accordingly, our ability to continue to provide service in the geographic area covered by such license would be adversely affected. In addition, many of our licenses are subject to interim or final construction requirements. While we or the prior licensee have met the five-year construction benchmark, there is no guarantee that the FCC will find our construction sufficient to meet the applicable construction requirement, in which case the FCC could terminate our license and our ability to continue to provide service in that license area would be adversely affected. For some of our PCS licenses, we also have a 10 year construction obligation and for our AWS licenses we have a 15 year construction obligation. For all PCS and AWS licenses the FCC requires that a licensee provide substantial service in order to receive a renewal expectancy. There is no guarantee that the FCC will find our or the prior licensees’ system construction to meet any ten-year build-out requirement or construction requirements for renewal. Additionally, while incumbent licensees may enjoy a certain renewal expectancy if they provide substantial service, there is no guarantee that the FCC will conclude that we are providing substantial service, that we are entitled to a renewal expectancy, or will renew all or any of our licenses, or that the FCC will not grant the renewal with conditions that could materially and adversely affect our business. Failure to have our licenses renewed would materially and adversely affect our business.
The value of our licenses may drop in the future as a result of volatility in the marketplace and the sale of additional spectrum by the FCC.
     The market value of FCC licenses has been subject to significant volatility in the past and Congress has mandated that the FCC bring an additional substantial amount of spectrum to the market by auction in the next several years. The likely impact of these future auctions on license values is uncertain. For example, Congress has mandated that the FCC auction 60 MHz of spectrum in the 700 MHz band in early 2008 and another 40 MHz of AWS spectrum is in the process of being assigned for wireless broadband services and is expected to be auctioned in the future by the FCC. There can be no assurance of the market value of our FCC licenses or that the market value of our FCC licenses will not be volatile in the future. If the value of our licenses were to decline significantly, we could be forced to record non-cash impairment charges which could impact our ability to borrow additional funds. A significant impairment loss could have a material adverse effect on our operating income and on the carrying value of our licenses on our balance sheet.
The FCC may license additional spectrum which may not be appropriate for or available to us or which may allow new competitors to enter our markets.
     The FCC periodically makes additional spectrum available for wireless use. For instance, the FCC recently allocated and auctioned an additional 90 MHz of spectrum for AWS. The AWS band plan made some licenses available in small (Metropolitan Statistical Area (MSA) and Rural Service Area (RSA)) license areas, although the predominant amount of spectrum remains allocated on a regional basis in combinations of 10 MHz and 20 MHz spectrum blocks. This band plan tended to favor large incumbent carriers with nationwide footprints and presented challenges for us in acquiring additional spectrum. The FCC also has allocated an additional 40 MHz of spectrum devoted to AWS. It is in the process of considering the channel assignment policies for 20 MHz of this spectrum and has indicated that it will initiate a further proceeding with regard to the remaining 20 MHz in the future. The FCC also is in the process of taking comments on the appropriate geographic license areas and channel blocks for an additional 60 MHz of spectrum in the 700 MHz band. Specifically, on August 10, 2006, the FCC issued a Notice of Proposed Rulemaking seeking comment on possible changes to the 700 MHz band plan, including possible changes in the service area and channel block sizes for the 60 MHz of as yet unauctioned 700 MHz spectrum. We, along with other small, regional and rural carriers, filed comments advocating changes to the current 700 MHz bandplan to create a greater number of licenses with smaller spectrum blocks and geographic area sizes. Several national wireless carriers support the current plan and other interested parties have made band plan and licensing proposals that differ from ours by favoring larger license areas, larger license blocks and the use of combinatorial bidding, which we do not favor, to enable applicants to more easily assemble a nationwide foot print. In addition, one commenter advocates reassigning 30 MHz of the 700 MHz band which now is slated for commercial broadband use, to public safety use to create a nationwide, interoperable broadband network that public safety users can access on a priority basis. Another commenter advocates allocating 10 MHz of the 700 MHz band, which now is slated for commercial broadband use, on a nationwide basis, in accordance with specific public safety rules that would force the licensee to fund the construction of a nationwide broadband infrastructure, offer service only on a wholesale basis, and provide public safety with priority access to the 10 MHz of spectrum during emergencies. In September 2006, the FCC also sought comment on proposals to increase the flexibility of guard band licensees in the 700 MHz spectrum. Furthermore, in December 2006, the FCC sought comment on the possible implementation of a

nationwide broadband interoperable network in the 700 MHz band allocated for public safety use, which also could be used by commercial service providers on a secondary basis. We cannot predict the likely outcome of those proceedings or whether they will benefit or adversely affect us.
     There are a series of risks associated with any new allocation of broadband spectrum by the FCC. First, there is no assurance that the spectrum made available by the FCC will be appropriate for or complementary to our business plan and system requirements. Second, depending upon the quantity, nature and cost of the new spectrum, it is possible that we will not be granted any of the new spectrum and, therefore, we may have difficulty in providing new services. This could adversely affect the valuation of the licenses we already hold. Third, we may be unable to purchase additional spectrum or the prices paid for such spectrum may negatively affect our ability to be competitive in the market. Fourth, new spectrum may allow new competitors to enter our markets and impact our ability to grow our business and compete effectively in our market. Fifth, new spectrum may be sold at prices lower than we paid at past auctions or in private transactions, thus adversely affecting the value of our existing assets. Sixth, the clearing obligations for existing licensees on new spectrum may take longer or cost more than anticipated. Seventh, our competitors may be able to use this new spectrum to provide products and services that we cannot provide using our existing spectrum. Eighth, there can be no assurance that our competitors will not use certain FCC programs, such as its designated entity program or the proposed nationwide interoperable networks for public safety use, to purchase or acquire spectrum at materially lower prices than what we are required to pay. Any of these risks, if they occur, may have a material adverse effect on our business.
We are subject to numerous surcharges and fees from federal, state and local governments, and the applicability and amount of these fees is subject to great uncertainty and may prove to be material to our financial results.
     Telecommunications providers pay a variety of surcharges and fees on their gross revenues from interstate and intrastate services. Interstate surcharges include federal Universal Service Fund fees and common carrier regulatory fees. In addition, state regulators and local governments impose surcharges, taxes and fees on our services and the applicability of these surcharges and fees to our services is uncertain in many cases and jurisdictions may argue as to whether we have correctly assessed and remitted those monies. The division of our services between interstate services and intrastate services is a matter of interpretation and may in the future be contested by the FCC or state authorities. In addition, periodic revisions by state and federal regulators may increase the surcharges and fees we currently pay. The Federal government and many states apply transaction-based taxes to sales of our products and services and to our purchases of telecommunications services from various carriers. It is possible that our transaction based tax liabilities could change in the future. We may or may not be able to recover some or all of those taxes from our customers and the amount of taxes may deter demand for our services.
Spectrum for which we have been granted licenses as a result of AWS Auction 66 is subject to certain legal challenges, which may ultimately result in the FCC revoking our licenses.
     We have paid the full purchase price of approximately $1.4 billion to the FCC for the licenses we were granted as a result of Auction 66, even though there are ongoing uncertainties regarding some aspects of the final auction rules. In April 2006, the FCC adopted an Order relating to its DE program, or the DE Order. This Order was modified by the FCC in an Order on Reconsideration which largely upheld the revised DE rules but clarified that the FCC’s revised unjust enrichment rules would only apply to licenses initially granted after April 25, 2006. Several interested parties filed an appeal in the U.S. Court of Appeals for the Third Circuit on June 7, 2006, of the DE Order. The appeal challenges the DE Order on both substantive and procedural grounds. Among other claims, the petitions contest the FCC’s effort to apply the revised rules to applications for the AWS Auction 66 and seeks to overturn the results of Auction 66. We are unable at this time to predict the likely outcome of the court action. We also are unable to predict the likelihood that the litigation will result in any changes to the DE Order or to the DE program, and, if there are changes, whether or not any such changes will be beneficial or detrimental to our interests. If the court overturns the results of Auction 66, there may be a delay in us receiving a refund of our payments. Further, the FCC may appeal any decision overturning Auction 66 and not refund any amounts paid until the appeal is final. In such instance, we may be forced to pay interest on the payments made to the FCC without receiving any interest on such payments from the FCC. If the results of Auction 66 were overturned and we receive a refund, the delay in the return of our money and the loss of any amounts spent to develop the licenses in the interim may affect our financial results and the loss of the licenses may affect our business plan. Additionally, such refund would be without interest. In the meantime we would have been obligated to pay interest to our lenders on the amounts we advanced to the FCC during the interim period and such interest amounts may be material.

We may be delayed in starting operations in the Auction 66 Markets because the incumbent licensees may have unreasonable demands for relocation or may refuse to relocate.
     The spectrum allocated for AWS currently is utilized by a variety of categories of existing licensees (Broadband Radio Service, Fixed Service) as well as governmental users. The FCC rules provide that a portion of the money raised in Auction 66 will be used to reimburse the relocation costs of certain governmental users from the AWS band. However, not all governmental users are obligated to relocate. To foster the relocation of non-governmental incumbent licensees, the FCC also adopted a transition and cost sharing plan under which incumbent users can be reimbursed for relocating out of the AWS band with the costs of relocation being shared by AWS licensees benefiting from the relocation. The FCC has established rules requiring the new AWS licensee and the non-governmental incumbent user to negotiate voluntarily for up to three years before the non-governmental incumbent licensee is subject to mandatory relocation.
     We are not able to determine with any certainty the costs we may incur to relocate the non-governmental incumbent licenses in the Auction 66 Markets or the time it will take to clear the AWS spectrum in those areas.
     If any federal government users refuse to relocate out of the AWS band in a metropolitan area where we have been granted a license, we may be delayed or prevented from serving certain geographic areas or customers within the metropolitan area and such inability may have a material adverse effect on our financial performance, and our future prospects. In addition, if any of the incumbent users refuse to voluntarily relocate, we may be delayed in using the AWS spectrum granted to us and such delay may have a material adverse effect on our ability to serve the metropolitan areas, our financial performance, and our future prospects.
The FCC may adopt rules requiring new point-to-multipoint emergency alert capabilities that would require us to make costly investments in new network equipment and consumer handsets.
     In 2004, the FCC initiated a proceeding to update and modernize its systems for distributing emergency broadcast alerts. Television stations, radio broadcasters and cable systems currently are required to maintain emergency broadcast equipment capable of retransmitting emergency messages received from a federal agency. As part of its attempts to modernize the emergency alert system, the FCC in its proceeding is addressing the feasibility of requiring wireless providers, such as us, to distribute emergency information through our wireless networks. Unlike broadcast and cable networks, however, our infrastructure and protocols — like those of all other similarly-situated wireless broadband PCS carriers — are optimized for the delivery of individual messages on a point-to-point basis, and not for delivery of messages on a point-to-multipoint basis, such as all subscribers within a defined geographic area. While multiple proposals have been discussed in the FCC proceeding, including limited proposals to use existing SMS capabilities on a short-term basis, the FCC has not yet ruled and therefore we are not able to assess the short- and long-term costs of meeting any future FCC requirements to provide emergency and alert service, should the FCC adopt such requirements. Congress recently passed the Warning, Alert, and Response Network Act, or the Act, which was signed into law. In the Act, Congress provided for the establishment, within 60 days of enactment, of an advisory committee to provide recommendations to the FCC on, and the FCC is required to complete a proceeding to adopt, relevant technical standards, protocols, procedures and other technical requirements based on such recommendations necessary to enable alerting capability for commercial mobile radio service, or CMRS, providers that voluntarily elect to transmit emergency alerts. Under the Act, a CMRS carrier can elect not to participate in providing such alerting capability. If a CMRS carrier elects to participate, the carrier may not charge separately for the alerting capability and the CMRS carrier’s liability related to or any harm resulting from the transmission of, or failure to transmit, an emergency is limited. Within a relatively short period of time after receiving the recommendations from the advisory committee, the FCC is obligated to complete its rulemaking implementing such rules. Adoption of such requirements, however, could require us to purchase new or additional equipment and may also require consumers to purchase new handsets. Until the FCC rules, we do not know if it will adopt such requirements, and if it does, what their impact will be on our network and service.
FCC approval for the sale of our stock, if required, may not be forthcoming or may result in adverse conditions to the business or to the holders of our stock.
     If the sale of our stock would cause a change in control of us under the Communications Act of 1934, as amended and the FCC’s rules, regulations or policies promulgated thereunder, the prior approval of the FCC would be required prior to any such sale. There can be no assurance that, at the time the sale is contemplated, the FCC would grant such an approval, or that the FCC would grant such an approval without adverse conditions.

General Matters
We are currently controlled by a limited number of stockholders, and their interests may be different from yours.
     A significant portion of the voting power of our capital stock is concentrated in the hands of a few shareholders who also are either members of our board of directors or can appoint directors to the board. M/C Venture Partners, Accel Partners, TA Associates, Madison Dearborn Partners, and Mr. Roger D. Linquist, our President, Chief Executive Officer, and Chairman of the Board, all can appoint members to our board of directors and these stockholders, along with the holders of our Series D Preferred Stock as a class, elect a majority of our directors. In addition, all of our directors collectively own or control in excess of 50% of the voting power of the shares of our capital stock on an as-converted basis. Stockholders holding over 10% of the voting power also hold collectively in excess of 38% of the voting power of our capital stock. These stockholders will have the ability to significantly influence whether required consents can be obtained and thus influence our ability to enter into significant corporate transactions and these stockholders may have different interests than the other holders of our common stock.
Ownership of shares of our common stock, Series D Preferred Stock and/or Series E Preferred Stock is an illiquid investment.
     Although we have filed a registration statement for an initial public offering of our common stock and have applied to list our stock on the New York Stock Exchange upon completion of the offering, there is currently no established trading market for the shares of our common stock, Series D Preferred Stock and Series E Preferred Stock. There can be no assurance that our initial public offering will be successful or that a trading market will develop. Holders of shares of common stock and preferred stock are subject to the transfer limitations contained in the Second Amended and Restated Stockholders Agreement, dated August 30, 2005, as amended, by and between us and certain of our stockholders, including, among other things, co-sale rights of other stockholders. The co-sale rights make it less likely that a stockholder desiring to sell his, her or its equity interest will be able to sell any amount of its investment in excess of the percentage ownership of us held by such stockholder. As such, a continuing investment in the shares of common stock and/or preferred stock may result in a lack of liquidity with respect to such stock for an indefinite period of time.
Our stockholder rights plan could prevent a change in control of our Company in instances in which some stockholders may believe a change in control is in their best interests.
     In connection with our planned initial public offering, our board of directors has approved entering into a rights agreement that establishes our stockholder rights plan, or Rights Plan. Pursuant to the Rights Plan, we will issue to our stockholders one preferred stock purchase right for each outstanding share of our common stock as of March 27, 2007. Each right, when exercisable, will entitle its holder to purchase from us a unit consisting of one one-thousandth of a share of series A junior participating preferred stock at a purchase price to be determined by our board of directors at the time the Rights Plan was adopted. Our Rights Plan is intended to protect stockholders in the event of an unfair or coercive offer to acquire our Company and to provide our board of directors with adequate time to evaluate unsolicited offers. The Rights Plan may have anti-takeover effects. The Rights Plan will cause substantial dilution to a person or group that attempts to acquire us on terms that our board of directors does not believe are in our best interests and those of our stockholders and may discourage, delay or prevent a merger or acquisition that stockholders may consider favorable, including transactions in which stockholders might otherwise receive a premium for their shares.
Conflicts of interest may arise because some of our directors are principals of our stockholders, and we have waived our rights to certain corporate opportunities.
     Our board of directors includes representatives from Accel Partners, TA Associates, Madison Dearborn Capital Partners and M/C Venture Partners. Those stockholders and their respective affiliates may invest in entities that directly or indirectly compete with us or companies in which they are currently invested may already compete with us. As a result of these relationships, when conflicts between the interests of those stockholders or their respective affiliates and the interests of our other stockholders arise, these directors may not be disinterested. Under Delaware law, transactions that we enter into in which a director or officer has a conflict of interest are generally permissible so long as (1) the material facts relating to the director’s or officer’s relationship or interest as to the transaction are

disclosed to our board of directors and a majority of our disinterested directors approves the transaction, (2) the material facts relating to the director’s or officer’s relationship or interest as to the transaction are disclosed to our stockholders and a majority of our disinterested stockholders approves the transaction, or (3) the transaction is otherwise fair to us. Also, pursuant to the terms of our certificate of incorporation, our non-employee directors, including the representatives from Accel Partners, TA Associates, Madison Dearborn Capital Partners and M/C Venture Partners, are not required to offer us any corporate opportunity of which they become aware and could take any such opportunity for themselves or offer it to other companies in which they have an investment, unless such opportunity is expressly offered to them in their capacity as a director of our Company.
Item 1B. Unresolved Staff Comments
     None.
Item 2. Properties
     We currently maintain our executive offices in Dallas, Texas, and regional offices in Alameda, California; Sunrise, Florida; Norcross, Georgia; Folsom, California; Plano, Texas; Livonia, Michigan; Irvine, California; Tampa, Florida; and Orlando, Florida. As of December 31, 2006, we also operated 95 retail stores throughout our metropolitan areas. All of our regional offices, switch sites, retail stores and virtually all of our cell site facilities are leased from unaffiliated third parties. We believe these properties, which are being used for their intended purposes, are adequate and well-maintained.
Item 3. Legal Proceedings
     On June 14, 2006, Leap Wireless International, Inc. and Cricket Communications, Inc., or collectively Leap, filed suit against us in the United States District Court for the Eastern District of Texas, Marshall Division, Civil Action No. 2-06CV-240-TJW and amended on June 16, 2006, for infringement of U.S. Patent No. 6,813,497 “Method for Providing Wireless Communication Services and Network and System for Delivering of Same,” or the ’497 Patent, issued to Leap. The complaint seeks both injunctive relief and monetary damages for our alleged infringement of such patent. On August 3, 2006, we (i) answered the complaint, (ii) raised a number of affirmative defenses, and (iii) together with two related entities, counterclaimed against Leap and several related entities and certain current and former employees of Leap and certain of its related entities, including Leap’s CEO. We have also tendered Leap’s claims to the manufacturer of our network infrastructure equipment for indemnity and defense. In our counterclaims, we claim that we do not infringe any valid or enforceable claim of the ’497 Patent. Certain of the Leap defendants, including its CEO, answered our counterclaims on October 13, 2006. In its answer, Leap and its CEO denied our allegations and asserted affirmative defenses to our counterclaims. In connection with denying a motion to dismiss by certain individual defendants, the court concluded that our claims against those defendants were compulsory counterclaims. The court has set April 3, 2007 as the date for a scheduling conference at which time the Court will set the date for the Claim Construction hearing and trial. We plan to vigorously defend against Leap’s claims relating to the ’497 Patent.
     If Leap were successful in its claim for injunctive relief, we could be enjoined from operating our business in the manner we currently operate, which could require us to expend additional capital to change certain of our technologies and operating practices, or could prevent us from offering some or all of our services using some or all of our existing systems. In addition, if Leap were successful in its claim for monetary damage, we could be forced to pay Leap substantial damages for past infringement and/or ongoing royalties on a portion of our revenues, which could materially adversely impact our financial performance.
     On August 15, 2006, we filed a separate action in the California Superior Court, Stanislaus County, Case No. 382780, against Leap and others for unfair competition, misappropriation of trade secrets, interference with contracts, breach of contract, intentional interference with prospective business advantage, and trespass. In this suit we seek monetary and punitive damages and injunctive relief. Defendants responded to our complaint by filing demurrers on or about January 5, 2007 requesting that the Court dismiss the complaint. On February 1, 2007, the Court granted the demurrers in part and granted us leave to amend the complaint. We filed a First Amended Complaint on February 27, 2007. Defendant’s response to the First Amended Complaint is due March 28, 2007. We intend to vigorously prosecute this complaint.
     On September 22, 2006, Royal Street filed a separate action in the United States District Court for the Middle District of Florida, Tampa Division, Civil Action No. 8:06-CV-01754-T-23TBM, seeking a declaratory judgment that Leap’s ’497 Patent is invalid and not being infringed upon by Royal Street. Leap responded to Royal Street’s complaint by filing a motion to dismiss Royal Street’s complaint for lack of subject matter jurisdiction or, in the alternative, that the action be transferred to the United States District Court for the Eastern District of Texas, Marshall Division where Leap has brought suit against us under the same patent. Royal Street has responded to this motion. The Court has set a trial date in October 2008.

     In addition, we are involved in litigation from time to time, including litigation regarding intellectual property claims, that we consider to be in the normal course of business. We are not currently party to any other pending legal proceedings that we believe would, individually or in the aggregate, have a material adverse effect on our financial condition or results of operations.
Item 4. Submission of Matters to a Vote of Security Holders
     In December 2006, we submitted to our stockholders an amendment to our 2004 Equity Incentive Compensation Plan to increase the number of shares available for issuance to 18,600,000 and to make certain other changes. On December 13, 2006, we received approval of the amendment by written consent of greater than a majority of our stockholders.
PART II
Item 5. Market Price for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities
     There is no established public trading market for our common equity.
     As of December 31, 2006, we had 157,052,097 shares of common stock outstanding held by approximately 181 stockholders of record.
     We have never paid or declared any regular dividends on our common stock and do not intend to declare or pay regular dividends on our common stock in the foreseeable future. The terms of our senior secured credit facility restrict our ability to declare or pay dividends. We generally intend to retain the future earnings, if any, to invest in our business. Subject to Delaware law, our board of directors will determine the payment of future dividends on our common stock, if any, and the amount of any dividends in light of:
    any applicable contractual restrictions limiting our ability to pay dividends;
 
    our earnings and cash flows;
 
    our capital requirements;
 
    our financial condition; and
 
    other factors our board of directors deems relevant.

Non-Employee Director Remuneration Plan
     Non-employee members of our board of directors are eligible to participate in our non-employee director remuneration plan under which such directors may receive compensation for serving on the board of directors. This compensation includes annual retainers, board meeting fees, committee paid event fees, initial stock grants and annual stock grants. See Item 11, “Compensation of Directors” for further information regarding this plan.
Recent Sales of Unregistered Securities
     Set forth below is a listing of all sales of securities by MetroPCS Communications during the past three years not registered under the Securities Act:
     Series E Convertible Preferred Stock. In September 2005, MetroPCS Communications issued 500,000 shares of Series E Preferred Stock of MetroPCS Communications, to Madison Dearborn and TA Associates for an aggregate sales price of $50,000,000 pursuant to a Stock Purchase Agreement dated August 30, 2005 (“Series E Purchase Agreement”). This transaction was undertaken in reliance upon the accredited investors’ exemption from registration afforded by Rule 506 of Regulation D (“Rule 506”) of the Securities Act. We believe that other exemptions may also exist for this transaction. Each share of Series E Preferred Stock accrues dividends from the date of issuance at a rate of 6% per year on the liquidation value of $100 per share. Each share of Series E Preferred Stock will be converted into common stock upon (i) the completion of a Qualifying Public Offering, (as defined in the Second Amended and Restated Stockholders Agreement), (ii) the common stock trading (or, in the case of a merger or consolidation of MetroPCS Communications with another company, other than as a sale or change of control of MetroPCS Communications, the shares received in such merger or consolidation having traded immediately prior to such merger or consolidation) on a national securities exchange for a period of 30 consecutive trading dates above a price implying a market valuation of the Series D Preferred Stock over twice the Series D Preferred Stock initial purchase price, or (iii) the date specified by the holders of 662/3% of the Series E Preferred Stock. The Series E Preferred Stock is convertible into common stock at $9.00 per share, which per share amount is subject to adjustment in accordance with the terms of the Second Amended and Restated Articles of Incorporation of MetroPCS Communications. If not previously converted, MetroPCS Communications is required to redeem all outstanding shares of Series E Preferred Stock on July 17, 2015, at the liquidation preference of $100 per share plus accrued but unpaid dividends.
     In October 2005, in connection with the purchase of the Series E Preferred Stock, Madison Dearborn and TA Associates conducted a Tender Offer in which they purchased Series D Preferred Stock and common stock representing, together with their Series E Preferred Stock, approximately 34% of the common stock on a fully diluted basis at the time of purchase.
     Series D Convertible Preferred Stock. Between July 2000 and January 2004, MetroPCS issued 3,500,993 shares of Series D Preferred Stock, par value $0.0001 per share, of MetroPCS (“MetroPCS Series D Preferred Stock”), in multiple closings, for an aggregate sales price of $350,099,300. These transactions relied on the accredited investors’ exemption from registration requirements afforded by Rule 506. We believe that other exemptions may also exist for these transactions. In 2004, each share of MetroPCS Series D Preferred Stock was converted into Series D Preferred Stock. Each share of Series D Preferred Stock will be converted into common stock upon (i) the completion of a Qualifying Public Offering, (as defined in the Second Amended and Restated Stockholders Agreement), (ii) the common stock trades (or, in the case of a merger or consolidation of MetroPCS Communications with another company, other than as a sale or change of control of MetroPCS Communications, the shares received in such merger or consolidation having traded immediately prior to such merger or consolidation) on a national securities exchange for a period of 30 consecutive trading dates above a price that implies a market valuation of the Series D Preferred Stock in excess of twice the initial purchase price of the Series D Preferred Stock, or (iii) the date specified by the holders of 662/3% of the Series D Preferred Stock. The Series D Preferred Stock is convertible into common stock at $3.13 per share, which per share amount is subject to adjustment under the terms of the Second Amended and Restated Articles of Incorporation of MetroPCS Communications. If not previously converted, MetroPCS Communications is required to redeem all outstanding shares of Series D Preferred Stock on July 17, 2015, at the liquidation preference of $100 per share plus accrued but unpaid dividends.
     MetroPCS Restructuring Transaction. In connection with its formation, MetroPCS Communications, Inc., or MetroPCS Communications, issued 300 shares of its common stock to MetroPCS, Inc. on March 10, 2004 for an

51


Table of Contents

aggregate purchase price of $1,000. The transaction was deemed exempt from Securities Act registration under Section 4(2) of the Securities Act as a transaction by an issuer not involving any public offering. In April 2004, in connection with the abandoned initial public offering, MetroPCS, Inc., MetroPCS Communications, and MPCS Holdco Merger Sub, Inc., a wholly owned subsidiary of MetroPCS Communications (“Merger Sub”), entered into an Agreement and Plan of Merger in which Merger Sub and MetroPCS, Inc. agreed to merge with MetroPCS, Inc. as the surviving corporation. On the effective date of the merger, which was in July 2004, each share of Class A common stock of MetroPCS, Inc., par value $0.0001 per share, was automatically converted into one share of Class A common stock, par value $0.0001 per share, of MetroPCS Communications; each share of Class C common stock of MetroPCS, Inc., par value $0.0001 per share, (including each share of Class B non-voting common stock of MetroPCS, Inc. that was converted into Class C common stock of MetroPCS, Inc. in April 2004) was automatically converted into one share of Class C common stock, par value $0.0001 per share, of MetroPCS Communications; and each share of Series D Preferred Stock of MetroPCS, Inc. was automatically converted into one share of Series D Preferred Stock of MetroPCS Communications. In addition, each option to purchase MetroPCS, Inc. Class C common stock (including each option to purchase MetroPCS, Inc. Class B non-voting common stock that was converted into an option to purchase MetroPCS, Inc. Class C common stock in April 2004) was assumed by MetroPCS Communications, and if and when exercisable, shall be exercised for common stock in MetroPCS Communications. Further, each warrant outstanding to obtain Class C common stock (including each warrant to purchase MetroPCS, Inc. Class B non-voting common stock that was converted into a warrant to purchase MetroPCS, Inc. Class C common stock) in MetroPCS, Inc. was assumed by MetroPCS Communications and, if and when exercisable, shall be exercised for the same class of common stock in MetroPCS Communications. In April 2004, each share of Class B non-voting common stock in MetroPCS, Inc. was converted into one share of Class C common stock in MetroPCS, Inc. Concurrent with the conversion, MetroPCS, Inc. increased the number of Class C common stock shares to 300,000,000 and decreased the authorized number of Class B common stock shares to zero. On July 23, 2004 the Class C common stock of MetroPCS Communications was renamed common stock. These transactions are exempt from registration under Section 4(2) of the Securities Act as a transaction by an issuer not involving any public offering.
     Exchange of Common Stock. When MetroPCS, Inc. emerged from bankruptcy in October 1998, its Fifth Amended and Restated Certificate of Incorporation included a provision prohibiting the issuance of non-voting equity securities pursuant to our bankruptcy plan of reorganization and Section 1123(a)(6) of the Bankruptcy Code. After its emergence from bankruptcy, MetroPCS, Inc. issued shares of Class B non-voting common stock, which had been authorized by its certificate of incorporation in effect prior to the bankruptcy filing. The Class B common stock had no voting rights except as required by law. MetroPCS, Inc.’s board of directors has indicated that the continued inclusion of the prohibition on the issuance of non-voting equity securities after MetroPCS, Inc.’s emergence from bankruptcy was a mistake, and on August 30, 2005, MetroPCS filed a certificate of correction to remove this prohibition. In addition, MetroPCS, Inc.’s Seventh Amended and Restated Certificate of Incorporation retroactively rescinds any prohibition on the issuance of the non-voting equity securities and ratifies the authorization and issuance of the Class B common stock by MetroPCS, Inc.
     In April 2004, all of the shares of Class B non-voting common stock, par value $0.0001 per share, of MetroPCS, Inc. (“Class B Common Stock”) converted into shares of Class C common stock of MetroPCS, Inc.. In order to resolve any uncertainty regarding the validity of the common stock ultimately received in the conversion of Class B Common Stock, MetroPCS Communications entered into an exchange agreement with Madison Dearborn and TA Associates in August 2005 to exchange all the common stock, which had been issued in connection with the conversion of Class B Common Stock, that Madison Dearborn and TA Associates acquired as a result of their recent offer to purchase, along with all claims relating to the possible invalidity of the issuance of the Class B Common Stock for an equivalent number of shares of MetroPCS Communications common stock. In addition, in December 2005, we initiated an offer to exchange any remaining MetroPCS Communications common stock ultimately received in connection with the conversion of Class B Common Stock, along with any claims relating to the possible invalidity of the issuance of the Class B Common Stock, for an equivalent number of shares of MetroPCS Communications common stock. As a result, all shares of MetroPCS Communications common stock which were ultimately received in connection with the conversion of Class B Common Stock, along with all claims relating to the possible invalidity of the issuance of the Class B Common Stock, have been exchanged for new shares of MetroPCS Communications common stock. The transaction was deemed exempt from Securities Act registration under Section 4(2) of the Securities Act as a transaction by an issuer not involving any public offering.
     Equity Incentive Plans. Since January 1, 2004 through December 31, 2006, our employees have purchased 24,436,032 shares of MetroPCS Communications common stock through the exercise of outstanding options under

52


Table of Contents

the 1995 Plan for an aggregate sales price of approximately $9.8 million. Since January 1, 2004 through December 31, 2006, our employees have purchased 17,892 shares of MetroPCS Communications common stock through the exercise of outstanding options under our 2004 Equity Incentive Compensation Plan, as amended, or the 2004 Plan, for an aggregate sales price of approximately $0.1 million. These transactions were undertaken in reliance upon exemptions from Securities Act registration requirements afforded by Rule 701, Rule 506 and Section 4(2) of the Securities Act, except that we have determined that the issuance of options to purchase 1,959,296 shares of MetroPCS Communications common stock under the 1995 Plan and 2004 Plan since January 1, 2004 may not have been exempt from registration or qualification requirements under federal or state securities laws. Consequently, certain of these options and shares of MetroPCS Communications common stock may have been issued in violation of federal or state securities laws and may be subject to rescission. We intend to make a rescission offer as soon as practicable after the effective date of this offering to holders of any outstanding options and shares subject to rescission. If the rescission offer is accepted by all offerees, we could be required to make an aggregate payment of up to approximately $2.6 million.
     Director Remuneration Plan. Non-employee members of our board of directors are eligible to participate in our non-employee director remuneration plan under which such directors may receive compensation for serving on the board of directors. This compensation includes annual retainers, board meeting fees, committee paid event fees, initial stock grants and annual stock grants. Non-employee directors are eligible to receive an initial grant of 120,000 options to purchase MetroPCS Communications common stock plus an additional 30,000 or 9,000 options to purchase MetroPCS Communications common stock if the member serves as the chairman of the audit committee or any of the other committees, respectively. Non-employee directors are also eligible to receive an annual grant of 30,000 options to purchase MetroPCS Communications common stock plus an additional 15,000 or 6,000 options to purchase MetroPCS Communications common stock if the member serves as the chairman of the audit committee or the other committees, respectively. In addition, non-employee directors may elect to receive their annual retainer in the form of MetroPCS Communications common stock. If such election is made, the non-employee director is eligible to receive the number of shares of MetroPCS Communications common stock that is equal to (a) the portion of the annual retainer received in MetroPCS Communications common stock divided by the fair market value of the MetroPCS Communications common stock at the time the annual retainer is paid (b) times three. Since the inception of the plan, non-employee directors have been granted 1,066,131 options to purchase MetroPCS Communications common stock and 97,596 of those options have been exercised. Shares of MetroPCS Communications common stock granted under the non-employee director remuneration plan were granted in reliance upon Rule 506 of the Securities Act and options were granted in reliance upon Rule 701 and/or Rule 506 of the Securities Act. We believe other exemptions may also be available.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations
Company Overview
     Except as expressly stated, the financial condition and results of operations discussed throughout Management’s Discussion and Analysis of Financial Condition and Results of Operations are those of MetroPCS Communications, Inc. and its consolidated subsidiaries.
     We are a wireless telecommunications carrier that currently offers wireless broadband personal communication services, or PCS, primarily in the greater Atlanta, Dallas/Ft. Worth, Detroit, Miami, San Francisco, Sacramento and Tampa/Sarasota/Orlando metropolitan areas. We launched service in the greater Atlanta, Miami and

54


Table of Contents

Sacramento metropolitan areas in the first quarter of 2002; in San Francisco in September 2002; in Tampa/Sarasota in October 2005; in Dallas/Ft. Worth in March 2006; in Detroit in April 2006; and Orlando in November 2006. In 2005, Royal Street Communications, LLC or Royal Street Communications, a company in which we own 85% of the limited liability company member interests and with which we have a wholesale arrangement allowing us to sell MetroPCS-branded services to the public, was granted licenses by the Federal Communications Commission, or FCC, in Los Angeles and various metropolitan areas throughout northern Florida. Royal Street is in the process of constructing its network infrastructure in its licensed metropolitan areas. We commenced commercial services in Orlando and certain portions of northern Florida in November 2006 and we expect to begin offering services in Los Angeles in the second or third quarter of 2007 through our arrangements with Royal Street Communications.
     As a result of the significant growth we have experienced since we launched operations, our results of operations to date are not necessarily indicative of the results that can be expected in future periods. Moreover, we expect that our number of customers will continue to increase, which will continue to contribute to increases in our revenues and operating expenses. In November 2006, we were granted advanced wireless services, or AWS, licenses covering a total unique population of approximately 117 million for an aggregate purchase price of approximately $1.4 billion. Approximately 69 million of the total licensed population associated with our Auction 66 licenses represents expansion opportunities in geographic areas outside of our Core and Expansion Markets, which we refer to as our Auction 66 Markets. These new expansion opportunities in our Auction 66 Markets cover six of the 25 largest metropolitan areas in the United States. The balance of our Auction 66 Markets, which cover a population of approximately 48 million, supplements or expands the geographic boundaries of our existing operations in Dallas/Ft. Worth, Detroit, Los Angeles, San Francisco and Sacramento. We currently plan to focus on building out approximately 40 million of the total population in our Auction 66 Markets with a primary focus on the New York, Philadelphia, Boston and Las Vegas metropolitan areas. Of the approximate 40 million total population, we are targeting launch of operations with an initial covered population of approximately 30 to 32 million by late 2008 or early 2009. Total estimated capital expenditures to the launch of these operations are expected to be between $18 and $20 per covered population, which equates to a total capital investment of approximately $550 million to $650 million. Total estimated expenditures, including capital expenditures, to become free cash flow positive, defined as Adjusted EBITDA less capital expenditures, is expected to be approximately $29 to $30 per covered population, which equates to $875 million to $1.0 billion based on an estimated initial covered population of approximately 30 to 32 million. We believe that our existing cash, cash equivalents and short-term investments, proceeds from our currently pending initial public offering, and our anticipated cash flows from operations will be sufficient to fully fund this planned expansion.
     We sell products and services to customers through our Company-owned retail stores as well as indirectly through relationships with independent retailers. We offer service which allows our customers to place unlimited local calls from within our local service area and to receive unlimited calls from any area while in our local service area, through flat rate monthly plans starting at $30 per month. For an additional $5 to $20 per month, our customers may select a service plan that offers additional services, such as unlimited nationwide long distance service, voicemail, caller ID, call waiting, text messaging, mobile Internet browsing, push e-mail and picture and multimedia messaging. We offer flat rate monthly plans at $30, $35, $40, $45 and $50 as fully described under “Business — MetroPCS Service Plans.” All of these plans require payment in advance for one month of service. If no payment is made in advance for the following month of service, service is discontinued at the end of the month that was paid for by the customer. For additional fees, we also provide international long distance and text messaging, ringtones, games and content applications, unlimited directory assistance, ring back tones, nationwide roaming and other value-added services. As of December 31, 2006, over 85% of our customers have selected either our $40 or $45 rate plans. Our flat rate plans differentiate our service from the more complex plans and long-term contract requirements of traditional wireless carriers. In addition the above products and services are offered by us in the Royal Street markets. Our arrangements with Royal Street are based on a wholesale model under which we purchase network capacity from Royal Street to allow us to offer our standard products and services in the Royal Street markets to MetroPCS customers under the MetroPCS brand name.
Critical Accounting Policies and Estimates
     The following discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America, or GAAP. You should read this discussion and analysis in conjunction with our consolidated financial statements and the related notes thereto contained elsewhere in this report. The preparation of these consolidated financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the reported amounts of certain assets, liabilities, revenues and expenses, and related

55


Table of Contents

disclosure of contingent assets and liabilities at the date of the financial statements. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.
     We believe the following critical accounting policies affect our more significant judgments and estimates used in the preparation of our consolidated financial statements.
   Revenue Recognition
     Our wireless services are provided on a month-to-month basis and are paid in advance. We recognize revenues from wireless services as they are rendered. Amounts received in advance are recorded as deferred revenue. Suspending service for non-payment is known as hotlining. We do not recognize revenue on hotlined customers.
     Revenues and related costs from the sale of accessories are recognized at the point of sale. The cost of handsets sold to indirect retailers are included in deferred charges until they are sold to and activated by customers. Amounts billed to indirect retailers for handsets are recorded as accounts receivable and deferred revenue upon shipment by us and are recognized as equipment revenues when service is activated by customers.
     Our customers have the right to return handsets within a specified time or after a certain amount of use, whichever occurs first. We record an estimate for returns as contra-revenue at the time of recognizing revenue. Our assessment of estimated returns is based on historical return rates. If our customers’ actual returns are not consistent with our estimates of their returns, revenues may be different than initially recorded.
     Effective July 1, 2003, we adopted Emerging Issues Task Force (“EITF”) No. 00-21, “Accounting for Revenue Arrangements with Multiple Deliverables,” (“EITF No. 00-21”), which is being applied on a prospective basis. EITF No. 00-21 also supersedes certain guidance set forth in U.S. Securities and Exchange Commission Staff Accounting Bulletin Number 101, “Revenue Recognition in Financial Statements,” (“SAB 101”). SAB 101 was amended in December 2003 by Staff Accounting Bulletin Number 104, “Revenue Recognition.” The consensus addresses the accounting for arrangements that involve the delivery or performance of multiple products, services and/or rights to use assets. Revenue arrangements with multiple deliverables are divided into separate units of accounting and the consideration received is allocated among the separate units of accounting based on their relative fair values.
     We determined that the sale of wireless services through our direct and indirect sales channels with an accompanying handset constitutes revenue arrangements with multiple deliverables. Upon adoption of EITF No. 00-21, we began dividing these arrangements into separate units of accounting, and allocating the consideration between the handset and the wireless service based on their relative fair values. Consideration received for the handset is recognized as equipment revenue when the handset is delivered and accepted by the customer. Consideration received for the wireless service is recognized as service revenues when earned.
   Allowance for Uncollectible Accounts Receivable
     We maintain allowances for uncollectible accounts for estimated losses resulting from the inability of our independent retailers to pay for equipment purchases and for amounts estimated to be uncollectible for intercarrier compensation. We estimate allowances for uncollectible accounts from independent retailers based on the length of time the receivables are past due, the current business environment and our historical experience. If the financial condition of a material portion of our independent retailers were to deteriorate, resulting in an impairment of their ability to make payments, additional allowances may be required. In circumstances where we are aware of a specific carrier’s inability to meet its financial obligations to us, we record a specific allowances for intercarrier compensation against amounts due, to reduce the net recognized receivable to the amount we reasonably believe will be collected. Total allowance for uncollectible accounts receivable as of December 31, 2006 was approximately 7% of the total amount of gross accounts receivable.

Table of Contents

     Inventories
          We write down our inventory for estimated obsolescence or unmarketable inventory equal to the difference between the cost of inventory and the estimated market value or replacement cost based upon assumptions about future demand and market conditions. Total inventory reserves for obsolescent and unmarketable inventory were not significant as of December 31, 2006. If actual market conditions are less favorable than those projected, additional inventory write-downs may be required.
     Deferred Income Tax Asset and Other Tax Reserves
          We assess our deferred tax asset and record a valuation allowance, when necessary, to reduce our deferred tax asset to the amount that is more likely than not to be realized. We have considered future taxable income, taxable temporary differences and ongoing prudent and feasible tax planning strategies in assessing the need for the valuation allowance. Should we determine that we would not be able to realize all or part of our net deferred tax asset in the future, an adjustment to the deferred tax asset would be charged to earnings in the period we made that determination.
          We establish reserves when, despite our belief that our tax returns are fully supportable, we believe that certain positions may be challenged and ultimately modified. We adjust the reserves in light of changing facts and circumstances. Our effective tax rate includes the impact of income tax related reserve positions and changes to income tax reserves that we consider appropriate. A number of years may elapse before a particular matter for which we have established a reserve is finally resolved. Unfavorable settlement of any particular issue may require the use of cash or a reduction in our net operating loss carryforwards. Favorable resolution would be recognized as a reduction to the effective rate in the year of resolution. Tax reserves as of December 31, 2006 were $23.9 million of which $4.4 million and $19.5 million are presented on the consolidated balance sheet in accounts payable and accrued expenses and other long-term liabilities, respectively.
     Property and Equipment
          Depreciation on property and equipment is applied using the straight-line method over the estimated useful lives of the assets once the assets are placed in service, which are ten years for network infrastructure assets including capitalized interest, three to seven years for office equipment, which includes computer equipment, three to seven years for furniture and fixtures and five years for vehicles. Leasehold improvements are amortized over the shorter of the remaining term of the lease and any renewal periods reasonably assured or the estimated useful life of the improvement. The estimated life of property and equipment is based on historical experience with similar assets, as well as taking into account anticipated technological or other changes. If technological changes were to occur more rapidly than anticipated or in a different form than anticipated, the useful lives assigned to these assets may need to be shortened, resulting in the recognition of increased depreciation expense in future periods. Likewise, if the anticipated technological or other changes occur more slowly than anticipated, the life of the assets could be extended based on the life assigned to new assets added to property and equipment. This could result in a reduction of depreciation expense in future periods.
          We assess the impairment of long-lived assets whenever events or changes in circumstances indicate the carrying value may not be recoverable. Factors we consider important that could trigger an impairment review include significant underperformance relative to historical or projected future operating results or significant changes in the manner of use of the assets or in the strategy for our overall business. The carrying amount of a long-lived asset is not recoverable if it exceeds the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the asset. When we determine that the carrying value of a long-lived asset is not recoverable, we measure any impairment based upon a projected discounted cash flow method using a discount rate we determine to be commensurate with the risk involved and would be recorded as a reduction in the carrying value of the related asset and charged to results of operations. If actual results are not consistent with our assumptions and estimates, we may be exposed to an additional impairment charge associated with long-lived assets. The carrying value of property and equipment was approximately $1.3 billion as of December 31, 2006.
     FCC Licenses and Microwave Relocation Costs
          We operate broadband PCS networks under licenses granted by the FCC for a particular geographic area on spectrum allocated by the FCC for broadband PCS services. In addition, in November 2006, we acquired a number

57


Table of Contents

of AWS licenses which can be used to provide services comparable to the PCS services provided by us, and other advanced wireless services. The PCS licenses included the obligation to relocate existing fixed microwave users of our licensed spectrum if our spectrum interfered with their systems and/or reimburse other carriers (according to FCC rules) that relocated prior users if the relocation benefits our system. Additionally, we incurred costs related to microwave relocation in constructing our PCS network. The PCS and AWS licenses and microwave relocation costs are recorded at cost. Although FCC licenses are issued with a stated term, ten years in the case of PCS licenses and fifteen years in the case of AWS licenses, the renewal of PCS and AWS licenses is generally a routine matter without substantial cost and we have determined that no legal, regulatory, contractual, competitive, economic, or other factors currently exist that limit the useful life of our PCS and AWS licenses. The carrying value of FCC licenses and microwave relocation costs was approximately $2.1 billion as of December 31, 2006.
          Our primary indefinite-lived intangible assets are our FCC licenses. Based on the requirements of Statement of Financial Accounting Standards (“SFAS”) No. 142, “Goodwill and other Intangible Assets,” (“SFAS No. 142”) we test investments in our FCC licenses for impairment annually or more frequently if events or changes in circumstances indicate that the carrying value of our FCC licenses might be impaired. We perform our annual FCC license impairment test as of each September 30th. The impairment test consists of a comparison of the estimated fair value with the carrying value. We estimate the fair value of our FCC licenses using a discounted cash flow model. Cash flow projections and assumptions, although subject to a degree of uncertainty, are based on a combination of our historical performance and trends, our business plans and management’s estimate of future performance, giving consideration to existing and anticipated competitive economic conditions. Other assumptions include our weighted average cost of capital and long-term rate of growth for our business. We believe that our estimates are consistent with assumptions that marketplace participants would use to estimate fair value. We corroborate our determination of fair value of the FCC licenses, using the discounted cash flow approach described above, with other market-based valuation metrics. Furthermore, we segregate our FCC licenses by regional clusters for the purpose of performing the impairment test because each geographical region is unique. An impairment loss would be recorded as a reduction in the carrying value of the related indefinite-lived intangible asset and charged to results of operations. Historically, we have not experienced significant negative variations between our assumptions and estimates when compared to actual results. However, if actual results are not consistent with our assumptions and estimates, we may be required to record to an impairment charge associated with indefinite-lived intangible assets. Although we do not expect our estimates or assumptions to change significantly in the future, the use of different estimates or assumptions within our discounted cash flow model when determining the fair value of our FCC licenses or using a methodology other than a discounted cash flow model could result in different values for our FCC licenses and may affect any related impairment charge. The most significant assumptions within our discounted cash flow model are the discount rate, our projected growth rate and management’s future business plans. A change in management’s future business plans or disposition of one or more FCC licenses could result in the requirement to test certain other FCC licenses. If any legal, regulatory, contractual, competitive, economic or other factors were to limit the useful lives of our indefinite-lived FCC licenses, we would be required to test these intangible assets for impairment in accordance with SFAS No. 142 and amortize the intangible asset over its remaining useful life.
          For the license impairment test performed as of December 31, 2006, the fair value of the FCC licenses was in excess of its carrying value. A 10% change in the estimated fair value of the FCC licenses would not have impacted the results of our annual license impairment test.
     Share-Based Payments
          We account for share-based awards exchanged for employee services in accordance with SFAS No. 123(R), “Share-Based Payment,” (“SFAS No. 123(R)”). Under SFAS No. 123(R), share-based compensation cost is measured at the grant date, based on the estimated fair value of the award, and is recognized as expense over the employee’s requisite service period. We adopted SFAS No. 123(R) on January 1, 2006. Prior to 2006, we recognized stock-based compensation expense for employee share-based awards based on their intrinsic value on the date of grant pursuant to Accounting Principles Board (“APB”) Opinion No. 25, “Accounting for Stock Issued to Employees,” (“APB No. 25”) and followed the disclosure requirements of SFAS No. 148, “Accounting for Stock-Based Compensation — Transition and Disclosure,” (“SFAS No. 148”), which amends the disclosure requirements of SFAS No. 123, “Accounting for Stock-Based Compensation,” (“SFAS No. 123”).
          We adopted SFAS No. 123(R) using the modified prospective transition method. Under the modified prospective transition method, prior periods are not revised for comparative purposes. The valuation provisions of

58


Table of Contents

SFAS No. 123(R) apply to new awards and to awards that are outstanding on the effective date and subsequently modified or cancelled. Compensation expense, net of estimated forfeitures, for awards outstanding at the effective date is recognized over the remaining service period using the compensation cost calculated under SFAS No. 123 in prior periods.
     We have granted nonqualified stock options. Most of our stock option awards include a service condition that relates only to vesting. The stock option awards generally vest in one to four years from the grant date. Compensation expense is amortized on a straight-line basis over the requisite service period for the entire award, which is generally the maximum vesting period of the award.
     The determination of the fair value of stock options using an option-pricing model is affected by our common stock valuation as well as assumptions regarding a number of complex and subjective variables. The methods used to determine these variables are generally similar to the methods used prior to 2006 for purposes of our pro forma information under SFAS No. 148. Factors that our Board of Directors considers in determining the fair market value of our common stock, include the recommendation of our finance and planning committee and of management based on certain data, including discounted cash flow analysis, comparable company analysis and comparable transaction analysis, as well as contemporaneous valuation reports. The volatility assumption is based on a combination of the historical volatility of our common stock and the volatilities of similar companies over a period of time equal to the expected term of the stock options. The volatilities of similar companies are used in conjunction with our historical volatility because of the lack of sufficient relevant history equal to the expected term. The expected term of employee stock options represents the weighted-average period the stock options are expected to remain outstanding. The expected term assumption is estimated based primarily on the stock options’ vesting terms and remaining contractual life and employees’ expected exercise and post-vesting employment termination behavior. The risk-free interest rate assumption is based upon observed interest rates on the grant date appropriate for the term of the employee stock options. The dividend yield assumption is based on the expectation of no future dividend payouts by us.
     As share-based compensation expense under SFAS No. 123(R) is based on awards ultimately expected to vest, it is reduced for estimated forfeitures. SFAS No. 123(R) requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. We recorded stock-based compensation expense of approximately $14.5 million for the year ended December 31, 2006.
     The value of the options is determined by using a Black-Scholes pricing model that includes the following variables: 1) exercise price of the instrument, 2) fair market value of the underlying stock on date of grant, 3) expected life, 4) estimated volatility and 5) the risk-free interest rate. The Company utilized the following weighted-average assumptions in estimating the fair value of the options grants for the years ended December 31, 2006 and 2005:
                 
    December 31,   December 31,
    2006   2005
Expected dividends
    0.00 %     0.00 %
Expected volatility
    35.04 %     50.00 %
Risk-free interest rate
    4.64 %     4.24 %
Expected lives in years
    5.00       5.00  
Weighted-average fair value of options:
               
Granted at below fair value
  $ 10.16     $  
Granted at fair value
  $ 3.75     $ 3.44  
Weighted-average exercise price of options:
               
Granted at below fair value
  $ 1.49     $  
Granted at fair value
  $ 9.95     $ 7.13  
          The Black-Scholes model requires the use of subjective assumptions including expectations of future dividends and stock price volatility. Such assumptions are only used for making the required fair value estimate and should not be considered as indicators of future dividend policy or stock price appreciation. Because changes in the subjective assumptions can materially affect the fair value estimate, and because employee stock options have characteristics significantly different from those of traded options, the use of the Black-Scholes option pricing model may not provide a reliable estimate of the fair value of employee stock options.
          During the years ended December 31, 2005 and 2006, the following awards were granted under the Company’s Option Plans:

Valuation of Common Stock
     Significant Factors, Assumptions, and Methodologies Used in Determining the Fair Value of our Common Stock.
     The determination of the fair value of our common stock requires us to make judgments that are complex and inherently subjective. Factors that our Board of Directors considers in determining the fair market value of our common stock include the recommendation of our finance and planning committee and of management based on certain data, including discounted cash flow analysis, comparable company analysis and comparable transaction analysis, as well as contemporaneous valuation reports. When determining the fair value of our common stock, we follow the guidance prescribed by the American Institute of Certified Public Accountants in its practice aid, “Valuation of Privately-Held-Company Equity Securities Issued as Compensation,” (the “Practice Aid”).
     According to the Practice Aid, quoted market prices in active markets are the best evidence of fair value of a security and should be used as the basis for the measurement of fair value, if available. Since quoted market prices for our securities are not available, the estimate of fair value should be based on the best information available, including prices for similar securities and the results of using other valuation techniques. Privately held enterprises or shareholders sometimes engage in arm’s-length cash transactions with unrelated parties for the issuance or sale of their equity securities, and the cash exchanged in such a transaction is, under certain conditions, an observable price that serves the same purpose as a quoted market price. Those conditions are (a) the equity securities in the transaction are the same securities as those with the fair value determination is being made, and (b) the transaction is a current transaction between willing parties. To the extent that arm’s-length cash transactions were available, we utilized those transactions to determine the fair value of our common stock. When arm’s-length transactions as described above were not available, then we utilized other valuation techniques based on a number of methodologies and analyses, including:
    discounted cash flow analysis;
 
    comparable company market multiples; and
 
    comparable merger and acquisition transaction multiples.
     Sales of our common stock in arm’s-length cash transactions during the years ended December 31, 2005 and 2006 were as follows:
                         
    Number of     Price     Gross  
    Shares     per Share     Proceeds  
October 2005
    48,847,533     $ 7.15     $ 349,422,686

    1,375,488     $ 8.67       11,920,896  
October 2006
    1,654,050     $ 8.67       14,335,100

Customer Recognition and Disconnect Policies
     When a new customer subscribes to our service, the first month of service and activation fee is included with the handset purchase. Under GAAP, we are required to allocate the purchase price to the handset and to the

60


Table of Contents

wireless service revenue. Generally, the amount allocated to the handset will be less than our cost, and this difference is included in Cost Per Gross Addition, or CPGA. We recognize new customers as gross customer additions upon activation of service. Prior to January 23, 2006, we offered our customers the Metro Promise, which allowed a customer to return a newly purchased handset for a full refund prior to the earlier of 7 days or 60 minutes of use. Beginning on January 23, 2006, we expanded the terms of the Metro Promise to allow a customer to return a newly purchased handset for a full refund prior to the earlier of 30 days or 60 minutes of use. Customers who return their phones under the Metro Promise are reflected as a reduction to gross customer additions. Customers’ monthly service payments are due in advance every month. Our customers must pay their monthly service amount by the payment date or their service will be suspended, or hotlined, and the customer will not be able to make or receive calls on our network. However, a hotlined customer is still able to make E-911 calls in the event of an emergency. There is no service grace period. Any call attempted by a hotlined customer is routed directly to our interactive voice response system and customer service center in order to arrange payment. If the customer pays the amount due within 30 days of the original payment date then the customer’s service is restored. If a hotlined customer does not pay the amount due within 30 days of the payment date the account is disconnected and counted as churn. Once an account is disconnected we charge a $15 reconnect fee upon reactivation to reestablish service and the revenue associated with this fee is deferred and recognized over the estimated life of the customer.
Revenues
     We derive our revenues from the following sources:
     Service. We sell wireless broadband PCS services. The various types of service revenues associated with wireless broadband PCS for our customers include monthly recurring charges for airtime, monthly recurring charges for optional features (including nationwide long distance and text messaging, ringtones, games and content applications, unlimited directory assistance, ring back tones, mobile Internet browsing, push e-mail and nationwide roaming) and charges for long distance service. Service revenues also include intercarrier compensation and nonrecurring activation service charges to customers.
     Equipment. We sell wireless broadband PCS handsets and accessories that are used by our customers in connection with our wireless services. This equipment is also sold to our independent retailers to facilitate distribution to our customers.
Costs and Expenses
     Our costs and expenses include:
     Cost of Service. The major components of our cost of service are:
    Cell Site Costs. We incur expenses for the rent of cell sites, network facilities, engineering operations, field technicians and related utility and maintenance charges.
 
    Intercarrier Compensation. We pay charges to other telecommunications companies for their transport and termination of calls originated by our customers and destined for customers of other networks. These variable charges are based on our customers’ usage and generally applied at pre-negotiated rates with other carriers, although some carriers have sought to impose such charges unilaterally.
 
    Variable Long Distance. We pay charges to other telecommunications companies for long distance service provided to our customers. These variable charges are based on our customers’ usage, applied at pre-negotiated rates with the long distance carriers.
     Cost of Equipment. We purchase wireless broadband PCS handsets and accessories from third-party vendors to resell to our customers and independent retailers in connection with our services. We subsidize the sale of handsets to encourage the sale and use of our services. We do not manufacture any of this equipment.
     Selling, General and Administrative Expenses. Our selling expense includes advertising and promotional costs associated with marketing and selling to new customers and fixed charges such as retail store rent and retail associates’ salaries. General and administrative expense includes support functions including, technical operations, finance, accounting, human resources, information technology and legal services. We record stock-based

61


Table of Contents

compensation expense in cost of service and selling, general and administrative expenses associated with employee stock options which is measured at the date of grant, based on the estimated fair value of the award. Prior to the adoption of SFAS No. 123(R), we recorded stock-based compensation expense at the end of each reporting period with respect to our variable stock options.
     Depreciation and Amortization. Depreciation is applied using the straight-line method over the estimated useful lives of the assets once the assets are placed in service, which are ten years for network infrastructure assets and capitalized interest, three to seven years for office equipment, which includes computer equipment, three to seven years for furniture and fixtures and five years for vehicles. Leasehold improvements are amortized over the term of the respective leases, which includes renewal periods that are reasonably assured, or the estimated useful life of the improvement, whichever is shorter.
     Interest Expense and Interest Income. Interest expense includes interest incurred on our borrowings, amortization of debt issuance costs and amortization of discounts and premiums on long-term debt. Interest income is earned primarily on our cash and cash equivalents.
     Income Taxes. As a result of our operating losses and accelerated depreciation available under federal tax laws, we paid no federal income taxes prior to 2006. For the year ended December 31, 2006, we paid approximately $2.7 million in federal income taxes. In addition, we have paid an immaterial amount of state income tax through December 31, 2006.
Seasonality
     Our customer activity is influenced by seasonal effects related to traditional retail selling periods and other factors that arise from our target customer base. Based on historical results, we generally expect net customer additions to be strongest in the first and fourth quarters. Softening of sales and increased customer turnover, or churn, in the second and third quarters of the year usually combine to result in fewer net customer additions. However, sales activity and churn can be strongly affected by the launch of new markets and promotional activity, which have the ability to reduce or outweigh certain seasonal effects.
Operating Segments
     Operating segments are defined by SFAS No. 131 “Disclosure About Segments of an Enterprise and Related Information,” (“SFAS No. 131”), as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker in deciding how to allocate resources and in assessing performance. Our chief operating decision maker is the Chairman of the Board and Chief Executive Officer.
     As of December 31, 2006, we had eight operating segments based on geographic region within the United States: Atlanta, Dallas/Ft. Worth, Detroit, Miami, San Francisco, Sacramento, Tampa/Sarasota/Orlando and Los Angeles. Each of these operating segments provide wireless voice and data services and products to customers in its service areas or is currently constructing a network in order to provide these services. These services include unlimited local and long distance calling, voicemail, caller ID, call waiting, text messaging, picture and multimedia messaging, international long distance and text messaging, ringtones, games and content applications, unlimited directory assistance, ring back tones, nationwide roaming, mobile Internet browsing, push e-mail and other value-added services.
     We aggregate our operating segments into two reportable segments: Core Markets and Expansion Markets.
    Core Markets, which include Atlanta, Miami, San Francisco, and Sacramento, are aggregated because they are reviewed on an aggregate basis by the chief operating decision maker, they are similar in respect to their products and services, production processes, class of customer, method of distribution, and regulatory environment and currently exhibit similar financial performance and economic characteristics.
 
    Expansion Markets, which include Dallas/Ft. Worth, Detroit, Tampa/Sarasota/Orlando and Los Angeles, are aggregated because they are reviewed on an aggregate basis by the chief operating decision maker, they are similar in respect to their products and services, production

Table of Contents

      processes, class of customer, method of distribution, and regulatory environment and have similar expected long-term financial performance and economic characteristics.
     The accounting policies of the operating segments are the same as those described in the summary of significant accounting policies. General corporate overhead, which includes expenses such as corporate employee labor costs, rent and utilities, legal, accounting and auditing expenses, is allocated equally across all operating segments. Corporate marketing and advertising expenses are allocated equally to the operating segments, beginning in the period during which we launch service in that operating segment. Expenses associated with our national data center are allocated based on the average number of customers in each operating segment. All intercompany transactions between reportable segments have been eliminated in the presentation of operating segment data.
     Interest expense, interest income, gain/loss on extinguishment of debt and income taxes are not allocated to the segments in the computation of segment operating profit for internal evaluation purposes.

          Service Revenues: Service revenues increased $418.8 million, or 48%, to $1,290.9 million for the year ended December 31, 2006 from $872.1 million for the year ended December 31, 2005. The increase is due to increases in Core Markets and Expansion Markets service revenues as follows:
    Core Markets. Core Markets service revenues increased $269.3 million, or 31%, to $1,138.0 million for the year ended December 31, 2006 from $868.7 million for the year ended December 31, 2005. The increase in service revenues is primarily attributable to net additions of

64


Table of Contents

      approximately 430,000 customers accounting for $199.2 million of the Core Markets increase, coupled with the migration of existing customers to higher price rate plans accounting for $70.1 million of the Core Markets increase.
 
      The increase in customers migrating to higher priced rate plans is primarily the result of our emphasis on offering additional services under our $45 rate plan which includes unlimited nationwide long distance and various unlimited data features. In addition, this migration is expected to continue as our higher priced rate plans become more attractive to our existing customer base.
 
    Expansion Markets. Expansion Markets service revenues increased $149.5 million to $152.9 million for the year ended December 31, 2006 from $3.4 million for the year ended December 31, 2005. These revenues were attributable to the launch of the Tampa/Sarasota metropolitan area in October 2005, the Dallas/Ft. Worth metropolitan area in March 2006, the Detroit metropolitan area in April 2006 and the expansion of the Tampa/Sarasota area to include the Orlando metropolitan area in November 2006. Net additions in the Expansion Markets totaled approximately 640,000 customers for the year ended December 31, 2006.
     Equipment Revenues: Equipment revenues increased $89.6 million, or 54%, to $255.9 million for the year ended December 31, 2006 from $166.3 million for the year ended December 31, 2005. The increase is due to increases in Core Markets and Expansion Markets equipment revenues as follows:
    Core Markets. Core Markets equipment revenues increased $44.6 million, or 27%, to $208.3 million for the year ended December 31, 2006 from $163.7 million for the year ended December 31, 2005. The increase in equipment revenues is primarily attributable to the sale of higher priced handset models accounting for $30.2 million of the increase, coupled with the increase in gross customer additions during the year of approximately 130,000 customers, which accounted for $14.4 million of the increase.
 
    Expansion Markets. Expansion Markets equipment revenues increased $45.0 million to $47.6 million for the year ended December 31, 2006 from $2.6 million for the year ended December 31, 2005. These revenues were attributable to the launch of the Tampa/Sarasota metropolitan area in October 2005, the Dallas/Ft. Worth metropolitan area in March 2006, the Detroit metropolitan area in April 2006 and the expansion of the Tampa/Sarasota area to include the Orlando metropolitan area in November 2006. Gross additions in the Expansion Markets totaled approximately 730,000 customers for the year ended December 31, 2006.
 
      The increase in handset model availability is primarily the result of our emphasis on enhancing our product offerings and appealing to our customer base in connection with our wireless services.
     Cost of Services: Cost of Service increased $162.1 million, or 57%, to $445.3 million for the year ended December 31, 2006 from $283.2 million for the year ended December 31, 2005. The increase is due to increases in Core Markets and Expansion Markets cost of service as follows:
    Core Markets. Core Markets cost of service increased $67.5 million, or 25%, to $338.9 million for the year ended December 31, 2006 from $271.4 million for the year ended December 31, 2005. The increase in cost of service was primarily attributable to a $14.8 million increase in federal universal service fund, or FUSF, fees, a $13.2 million increase in long distance costs, a $7.7 million increase in cell site and switch facility lease expense, a $6.4 million increase in customer service expense, a $5.9 million increase in intercarrier compensation, and a $4.3 million increase in employee costs, all of which are a result of the 23% growth in our Core Markets customer base and the addition of approximately 350 cell sites to our existing network infrastructure.
 
    Expansion Markets. Expansion Markets cost of service increased $94.6 million to $106.4 million for the year ended December 31, 2006 from $11.8 million for the year ended December 31, 2005. These increases were attributable to the launch of the Tampa/Sarasota metropolitan area in October 2005, the Dallas/Ft. Worth metropolitan area in March 2006, the Detroit metropolitan area in April 2006 and the expansion of the Tampa/Sarasota area to include the Orlando metropolitan area in November 2006. The increase in cost of service was primarily attributable to a $22.3 million increase in cell site and switch facility lease expense, a $13.8 million increase in

      employee costs, a $9.3 million increase in intercarrier compensation, $8.2 million in long distance costs, $8.2 million in customer service expense and $3.5 million in billing expenses.
     Cost of Equipment: Cost of equipment increased $176.0 million, or 59%, to $476.9 million for the year ended December 31, 2006 from $300.9 million for the year ended December 31, 2005. The increase is due to increases in Core Markets and Expansion Markets cost of equipment as follows:
    Core Markets. Core Markets cost of equipment increased $70.6 million, or 24%, to $364.3 million for the year ended December 31, 2006 from $293.7 million for the year ended December 31, 2005. The increase in equipment costs is primarily attributable to the sale of higher cost handset models accounting for $44.7 million of the increase. The increase in gross customer additions during the year of approximately 130,000 customers as well as the sale of new handsets to existing customers accounted for $25.9 million of the increase.
 
    Expansion Markets. Expansion Markets costs of equipment increased $105.4 million to $112.6 million for the year ended December 31, 2006 from $7.2 million for the year ended December 31, 2005. These costs were primarily attributable to the launch of the Tampa/Sarasota metropolitan area in October 2005, the Dallas/Ft. Worth metropolitan area in March 2006, the Detroit metropolitan area in April 2006 and the expansion of the Tampa/Sarasota area to include the Orlando metropolitan area in November 2006.
     Selling, General and Administrative Expenses. Selling, general and administrative expenses increased $81.1 million, or 50%, to $243.6 million for the year ended December 31, 2006 from $162.5 million for the year ended December 31, 2005. The increase is due to increases in Core Markets and Expansion Markets selling, general and administrative expenses as follows:
    Core Markets. Core Markets selling, general and administrative expenses increased $4.8 million, or 3%, to $158.1 million for the year ended December 31, 2006 from $153.3 million for the year ended December 31, 2005. Selling expenses increased by $10.7 million, or approximately 18% for the year ended December 31, 2006 compared to year ended December 31, 2005. General and administrative expenses decreased by $5.9 million, or approximately 6% for the year ended December 31, 2006 compared to the year ended December 31, 2005. The increase in selling expenses is primarily due to an increase in advertising and market research expenses which were incurred to support the growth in the Core Markets. This increase in selling expenses was offset by a decrease in general and administrative expenses, which were higher in 2005 because they included approximately $5.9 million in legal and accounting expenses associated with an internal investigation related to material weaknesses in our internal control over financial reporting as well as financial statement audits related to our restatement efforts.
 
    Expansion Markets. Expansion Markets selling, general and administrative expenses increased $76.3 million to $85.5 million for the year ended December 31, 2006 from $9.2 million for the year ended December 31, 2005. Selling expenses increased $31.5 million for the year ended December 31, 2006 compared to the year ended December 31, 2005. This increase in selling expenses was related to marketing and advertising expenses associated with the launch of the Dallas/Ft. Worth metropolitan area, the Detroit metropolitan area, and the expansion of the Tampa/Sarasota area to include the Orlando metropolitan area. General and administrative expenses increased by $44.8 million for the year ended December 31, 2006 compared to the same period in 2005 due to labor, rent, legal and professional fees and various administrative expenses incurred in relation to the launch of the Dallas/Ft. Worth metropolitan area, Detroit metropolitan area, and the expansion of the Tampa/Sarasota area to include the Orlando metropolitan area as well as build-out expenses related to the Los Angeles metropolitan area.
     Depreciation and Amortization. Depreciation and amortization expense increased $47.1 million, or 54%, to $135.0 million for the year ended December 31, 2006 from $87.9 million for the year ended December 31, 2005. The increase is primarily due to increases in Core Markets and Expansion Markets depreciation and amortization expense as follows:
    Core Markets. Core Markets depreciation and amortization expense increased $25.2 million, or

66


Table of Contents

      30%, to $109.6 million for the year ended December 31, 2006 from $84.4 million for the year ended December 31, 2005. The increase related primarily to an increase in network infrastructure assets placed into service during the year ended December 31, 2006. We added approximately 350 cell sites in our Core Markets during this period to increase the capacity of our existing network and expand our footprint.
 
    Expansion Markets. Expansion Markets depreciation and amortization expense increased $19.9 million to $21.9 million for the year ended December 31, 2006 from $2.0 million for the year ended December 31, 2005. The increase related to network infrastructure assets that were placed into service as a result of the launch of the Dallas/Ft. Worth metropolitan area, the Detroit metropolitan area, and expansion of the Tampa/Sarasota area to include the Orlando metropolitan area.
     Stock-Based Compensation Expense. Stock-based compensation expense increased $11.9 million, or 457%, to $14.5 million for the year ended December 31, 2006 from $2.6 million for the year ended December 31, 2005. The increase is primarily due to increases in Core Markets and Expansion Markets stock-based compensation expense as follows:
    Core Markets. Core Markets stock-based compensation expense increased $5.1 million, or 198%, to $7.7 million for the year ended December 31, 2006 from $2.6 million for the year ended December 31, 2005. The increase is primarily related to the adoption of SFAS No. 123(R) on January 1, 2006. In addition, in December 2006, we amended the stock option agreements of a former member of our board of directors to extend the contractual life of 405,054 vested options to purchase common stock until December 31, 2006. This amendment resulted in the recognition of additional stock-based compensation expense of approximately $4.1 million in the fourth quarter of 2006.
 
    Expansion Markets. Expansion Markets stock-based compensation expense was $6.8 million for the year ended December 31, 2006. This expense is attributable to stock options granted to employees in our Expansion Markets which are being accounted for under SFAS No. 123(R) as of January 1, 2006.

     Loss (Gain) on Disposal of Assets. In May 2005, we completed the sale of a 10 MHz portion of our 30 MHz PCS license in the San Francisco-Oakland-San Jose basic trading area for cash consideration of $230.0 million. The sale of PCS spectrum resulted in a gain on disposal of asset in the amount of $228.2 million.
     Loss on Extinguishment of Debt. In November 2006, we repaid all amounts outstanding under our first and second lien credit agreements and the exchangeable secured and unsecured bridge credit agreements. As a result, we recorded a loss on extinguishment of debt in the amount of approximately $42.7 million of the first and second lien credit agreements and an approximately $9.4 million loss on the extinguishment of the exchangeable secured and unsecured bridge credit agreements. In May 2005, we repaid all of the outstanding debt under our FCC notes, 103/4% senior notes and bridge credit agreement. As a result, we recorded a $1.9 million loss on the extinguishment of the FCC notes; a $34.0 million loss on extinguishment of the 103/4% senior notes; and a $10.4 million loss on the extinguishment of the bridge credit agreement.
     Interest Expense. Interest expense increased $58.0 million, or 100%, to $116.0 million for the year ended December 31, 2006 from $58.0 million for the year ended December 31, 2005. The increase in interest expense was primarily due to increased average principal balance outstanding as a result of additional borrowings of $150.0 million under our first and second lien credit agreements in the fourth quarter of 2005, $200.0 million under the secured bridge credit facility in the third quarter of 2006 and an additional $1,300.0 million under the secured and unsecured bridge credit facilities in the fourth quarter of 2006. Interest expense also increased due to the

Table of Contents

weighted average interest rate increasing to 10.30% for the year ended December 31, 2006 compared to 8.92% for the year ended December 31, 2005. The increase in interest expense was partially offset by the capitalization of $17.5 million of interest during the year ended December 31, 2006, compared to $3.6 million of interest capitalized during the same period in 2005. We capitalize interest costs associated with our FCC licenses and property and equipment beginning with pre-construction period administrative and technical activities, which includes obtaining leases, zoning approvals and building permits. The amount of such capitalized interest depends on the carrying values of the FCC licenses and construction in progress involved in those markets and the duration of the construction process. With respect to our FCC licenses, capitalization of interest costs ceases at the point in time in which the asset is ready for its intended use, which generally coincides with the market launch date. In the case of our property and equipment, capitalization of interest costs ceases at the point in time in which the network assets are placed into service. We expect capitalized interest to be significant during the construction of our additional Expansion Markets and related network assets.
     Provision for Income Taxes. Income tax expense for the year ended December 31, 2006 decreased to $36.7 million, which is approximately 41% of our income before provision for income taxes. For the year ended December 31, 2005 the provision for income taxes was $127.4 million, or approximately 39% of income before provision for income taxes. The year ended December 31, 2005 included a gain on the sale of a 10 MHz portion of our 30 MHz PCS license in the San Francisco-Oakland-San Jose basic trading area in the amount of $228.2 million.
     Net Income. Net income decreased $144.9 million, or 73%, to $53.8 million for the year ended December 31, 2006 compared to $198.7 million for the year ended December 31, 2005. The significant decrease is primarily attributable to our non-recurring sale of a 10 MHz portion of our 30 MHz PCS license in the San Francisco-Oakland-San Jose basic trading area in May 2005 for cash consideration of $230.0 million. The sale of PCS spectrum resulted in a gain on disposal of asset in the amount of $139.2 million, net of income taxes. Net income for the year ended December 31, 2006, excluding the tax effected impact of the gain on the sale of the PCS license, decreased approximately 10%. The decrease in net income, excluding the tax effected impact of the gain on the sale of spectrum, is primarily due to the increase in operating losses in our Expansion Markets. This increase in operating losses in our Expansion Markets is attributable to the launch of the Dallas/Ft. Worth metropolitan area in March 2006, the Detroit metropolitan area in April 2006, and the expansion of the Tampa/Sarasota area to include the Orlando metropolitan area in November 2006 as well as build-out expenses related to the Los Angeles metropolitan area.
     We have obtained positive operating income in our Core Markets at or before five full quarters of operations. Based on our experience to date in our Expansion Markets and current industry trends, we expect our Expansion Markets to achieve positive operating income in a period similar to or better than the Core Markets.

          Service Revenues. Service revenues increased $255.7 million, or 41%, to $872.1 million for the year ended December 31, 2005 from $616.4 million for the year ended December 31, 2004. The increase is due to increases in Core Markets and Expansion Markets service revenues as follows:
    Core Markets. Core Markets service revenues increased $252.3 million, or 41%, to $868.7 million for the year ended December 31, 2005 from $616.4 million for the year ended December 31, 2004. The increase in service revenues is primarily attributable to net additions of approximately 473,000 customers accounting for $231.8 million of the Core Markets increase, coupled with the migration of existing customers to higher priced rate plans accounting for

69


Table of Contents

      $20.5 million of the Core Markets increase.
 
      The increase in customers migrating to higher priced rate plans is primarily the result of our emphasis on offering additional services under our $45 rate plan which includes unlimited nationwide long distance and various unlimited data features. In addition, this migration is expected to continue as our higher priced rate plans become more attractive to our existing customer base.
 
    Expansion Markets. Expansion Markets service revenues were $3.4 million for the year ended December 31, 2005. These revenues are attributable to the launch of the Tampa/Sarasota metropolitan area in October 2005. Net additions in the Tampa/Sarasota metropolitan area totaled approximately 53,000 customers.
          Equipment Revenues. Equipment revenues increased $34.5 million, or 26%, to $166.3 million for the year ended December 31, 2005 from $131.8 million for the year ended December 31, 2004. The increase is due to increases in Core Markets and Expansion Markets equipment revenues as follows:

    Core Markets. Core Markets cost of service increased $70.6 million, or 35%, to $271.4 million for the year ended December 31, 2005 from $200.8 million for the year ended December 31, 2004. The increase was primarily attributable to a $12.9 million increase in intercarrier compensation, a $12.3 million increase in long distance costs, a $9.5 million increase in cell site and switch facility lease expense, a $5.6 million increase in customer service expense, a $3.9 million increase in billing expenses and $2.6 million increase in employee costs, which were a result of the 34% growth in our customer base and the addition of 315 cell sites to our existing network infrastructure.
 
    Expansion Markets. Expansion Markets cost of service was $11.8 million for the year ended December 31, 2005. These expenses are attributable to the launch of the Tampa/Sarasota metropolitan area in October 2005, which contributed net additions of approximately 53,000 customers during 2005.

      December 31, 2005. This cost is attributable to the launch of the Tampa/Sarasota metropolitan area in October 2005, which resulted in approximately 53,600 activations during 2005.
          Selling, General and Administrative Expenses. Selling, general and administrative expenses increased $31.0 million, or 24%, to $162.5 million for the year ended December 31, 2005 from $131.5 million for the year ended December 31, 2004. The increase is due to increases in Core Markets and Expansion Markets selling, general and administrative expenses as follows:
    Core Markets. Core Markets selling, general and administrative expenses increased $21.8 million, or 17%, to $153.3 million for the year ended December 31, 2005 from $131.5 million for the year ended December 31, 2004. Selling expenses increased by $6.3 million, or 12% for the year ended December 31, 2005 compared to 2004. General and administrative expenses increased by $15.5 million, or 20%, during 2005 compared to 2004. The significant increase in general and administrative expenses was primarily driven by increases in accounting and auditing fees of $4.9 million and increases in professional service fees of $3.6 million due to substantial legal and accounting expenses associated with an internal investigation related to material weaknesses in our internal control over financial reporting as well as financial statement audits related to our restatement efforts. We also experienced a $6.6 million increase in labor costs associated with new employee additions necessary to support the growth in our business. These increases were offset by a $7.8 million decrease in stock-based compensation expense.
 
    Expansion Markets. Expansion Markets selling, general and administrative expenses were $9.2 million for the year ended December 31, 2005. Selling expenses were $3.5 million and general and administrative expenses were $5.7 million for 2005.

Depreciation and amortization expense increased $25.7 million, or 41%, to $87.9 million for the year ended December 31, 2005 from $62.2 million for the year ended December 31, 2004. The increase is primarily due to increases in Core Markets and Expansion Markets depreciation expense as follows:
    Core Markets. Core Markets depreciation and amortization expense increased $23.1 million, or 38%, to $84.4 million for the year ended December 31, 2005 from $61.3 million for the year ended December 31, 2004. The increase related primarily to an increase in network infrastructure assets placed into service during 2005, compared to the year ended December 31, 2004. We added 315 cell sites in our Core Markets during the year ended December 31, 2005 to increase the capacity of our existing network and expand our footprint.
 
    Expansion Markets. Expansion Markets depreciation and amortization expense was $2.0 million for the year ended December 31, 2005. This expense is attributable to network infrastructure assets placed into service as a result of the launch of the Tampa/Sarasota metropolitan area.

          Loss (Gain) on Disposal of Assets. In May 2005, we completed the sale of a 10 MHz portion of our 30 MHz PCS license in the San Francisco-Oakland-San Jose basic trading area for cash consideration of $230.0 million. The sale of PCS spectrum resulted in a gain on disposal of asset in the amount of $228.2 million.
          (Gain) Loss on Extinguishment of Debt. In May 2005, we repaid all of the outstanding debt under our FCC notes, Senior Notes and bridge credit agreement. As a result, we recorded a $1.9 million loss on the extinguishment

of the FCC notes; a $34.0 million loss on extinguishment of the Senior Notes; and a $10.4 million loss on the extinguishment of the bridge credit agreement.
     Interest Expense. Interest expense increased $39.0 million, or 205%, to $58.0 million for the year ended December 31, 2005 from $19.0 million for the year ended December 31, 2004. The increase was primarily attributable to $40.9 million in interest expense related to our Credit Agreements that were executed on May 31, 2005 as well as the amortization of the deferred debt issuance costs in the amount of $3.6 million associated with the Credit Agreements. On May 31, 2005, we paid all of our outstanding obligations under our FCC notes and Senior Notes, which generally had lower interest rates than our Credit Agreements.
     Provision for Income Taxes. Income tax expense for year ended December 31, 2005 increased to $127.4 million, which is approximately 39% of our income before provision for income taxes. For the year ended December 31, 2004 the provision for income taxes was $47.0 million, or approximately 42% of income before provision for income taxes. The increase in our income tax expense in 2005 was attributable to our increased operating profits. The decrease in the effective tax rate from 2004 to 2005 relates primarily to the increase in book income which lowers the effective rate of tax items included in the calculation.
     Net Income. Net income increased $133.8 million, or 206%, for the year ended December 31, 2005 compared to the year ended December 31, 2004. The significant increase in net income is primarily attributable to our nonrecurring sale of a 10 MHz portion of our 30 MHz PCS license in the San Francisco-Oakland-San Jose basic trading area in May 2005 for cash consideration of $230.0 million. The sale of PCS spectrum resulted in a gain on disposal of asset in the amount of $139.2 million, net of income taxes. In addition, growth in average customers of approximately 37% during 2005 also contributed to the increase in net income for the year ended December 31, 2005. These increases were partially offset by a $46.5 million loss on extinguishment of debt.
Year Ended December 31, 2004 Compared to Year Ended December 31, 2003
     For the years ended December 31, 2004 and 2003, the consolidated summary information presented below represents Core Markets reportable segment information, as the Expansion Markets reportable segment had no operations until 2005.
     Set forth below is a summary of certain financial information for the periods indicated:

     Service Revenues. Service revenues increased $246.5 million, or 67%, to $616.4 million for the year ended December 31, 2004 from $369.9 million for the year ended December 31, 2003. The increase is primarily attributable to the addition of approximately 422,000 customers accounting for $159.7 million of the increase, coupled with the migration of existing customers to higher priced rate plans accounting for $86.8 million of the increase.
     The increase in customers migrating to higher priced rate plans is primarily the result of our emphasis on offering additional services under our $45 rate plan, which includes unlimited nationwide long distance and various unlimited data features. In addition, this migration is expected to continue as our higher priced rate plans become more attractive to our existing customer base.

     Equipment Revenues. Equipment revenues increased $50.6 million, or 62%, to $131.9 million for the year ended December 31, 2004 from $81.3 million for the year ended December 31, 2003. The increase is attributable to higher priced handset models accounting for $28.7 million of the increase; coupled with the increase in gross customer additions during the year of approximately 240,000 customers accounting for $21.9 million of the increase.
     The increase in handset model availability is primarily the result of our emphasis on enhancing our product offerings and appealing to our customer base in connection with our wireless services.
     Cost of Service. Cost of service increased $78.6 million, or 64%, to $200.8 million for the year ended December 31, 2004 from $122.2 million for the year ended December 31, 2003. The increase was attributable to the addition of approximately 422,000 customers during the year. Additionally, employee costs, cell site and switch facility lease expense and repair and maintenance expense increased as a result of the growth of our business and the expansion of our network.
     Cost of Equipment. Cost of equipment increased $71.9 million, or 48%, to $222.7 million for the year ended December 31, 2004 from $150.8 million for the year ended December 31, 2003. The increase in cost of equipment was due to a slight increase in the average handset cost per unit which related to an increase in sales of higher priced handset models in 2004. In addition, we experienced an increase in the number of handsets sold to new customers during the year.
     Selling, General and Administrative Expenses. Selling, general and administrative expenses increased $37.4 million, or 40%, to $131.5 million for the year ended December 31, 2004 from $94.1 million for the year ended December 31, 2003. Selling, general and administrative expenses include stock-based compensation expense, which increased $4.8 million, or 87%, to $10.4 million for the year ended December 31, 2004 from $5.6 million for the year ended December 31, 2003. This increase was primarily related to the extension of the exercise period of stock options for a terminated employee in the amount of approximately $3.6 million. The remaining increase was a result of an increase in the estimated fair market value of our stock used for valuing stock options accounted for under variable accounting. Selling expenses increased by $8.6 million as a result of increased sales and marketing activities. General and administrative expenses increased by $25.6 million primarily due to the increase in our administrative costs associated with our customer base and to network expansion, a $8.1 million increase in professional fees including legal and accounting services, a $3.7 million increase in employee salaries and benefits, a $3.6 million increase in bank service charges, a $0.5 million increase in rent expense, a $1.2 million increase in personal property tax expense, and a $1.1 million increase in property insurance. Of the $8.1 million increase in professional fees, approximately $3.2 million was related to the preparation of a registration statement for an initial public offering of our common stock to the public. These costs were expensed, as this initial public offering was not completed and the registration statement was withdrawn.
     Depreciation and Amortization. Depreciation and amortization expense increased $19.8 million, or 47%, to $62.2 million for the year ended December 31, 2004 from $42.4 million for the year ended December 31, 2003. The increase related primarily to an increase in network infrastructure assets placed into service in 2004. In-service base stations and switching equipment increased by approximately $237.2 million during the year ended December 31, 2004. In addition, we had 460 more cell sites in service at December 31, 2004 than at December 31, 2003. We expect depreciation to continue to increase due to the additional cell sites, switches and other network equipment that we plan to place in service to meet future customer growth and usage.
     Interest Expense. Interest expense increased $7.9 million, or 71%, to $19.0 million for the year ended December 31, 2004 from $11.1 million for the year ended December 31, 2003. The increase was primarily attributable to interest expense on our $150.0 million Senior Notes that were issued in September 2003.
     Provision for Income Taxes. Income tax expense for year ended December 31, 2004 increased to $47.0 million, which is approximately 42% of our income before provision for income taxes. For the year ended December 31, 2003 the provision for income taxes was $16.2 million, or approximately 51% of income before provision for income taxes. The increase in our income tax expense in 2004 was attributable to our increased operating profits. The decrease in the effective tax rate from 2003 to 2004 relates primarily to the increase in book income which lowers the effective rate of tax items included in the calculation. In addition, the 2003 income tax provision includes a charge required under California law to partially reduce the 2003 California net operating loss carryforwards. However, this statutory requirement did not exist in 2004.

     Net Income. Net income increased $49.5 million, or 323%, for the year ended December 31, 2004 compared to the year ended December 31, 2003. The increase in net income is primarily attributable to growth in average customers of approximately 56% for the year ended December 31, 2004 compared to the same period in 2003 in addition to the migration of existing customers to higher priced rate plans.

Performance Measures
     In managing our business and assessing our financial performance, we supplement the information provided by financial statement measures with several customer-focused performance metrics that are widely used in the wireless industry. These metrics include average revenue per user per month, or ARPU, which measures service revenue per customer; cost per gross customer addition, or CPGA, which measures the average cost of acquiring a new customer; cost per user per month, or CPU, which measures the non-selling cash cost of operating our business on a per customer basis; and churn, which measures turnover in our customer base. For a reconciliation of Non-GAAP performance measures and a further discussion of the measures, please read “— Reconciliation of Non-GAAP Financial Measures” below.
     The following table shows annual metric information for 2004, 2005 and 2006.

     Customers. Net customer additions were 1,016,365 for the year ended December 31, 2006, compared to 525,889 for the year ended December 31, 2005, an increase of 93%. Total customers were 2,940,986 as of December 31, 2006, an increase of 53% over the customer total as of December 31, 2005. Total customers as of December 31, 2005 were approximately 1.9 million, an increase of 38% over the total customers as of December 31, 2004. These increases are primarily attributable to the continued demand for our service offering.
     Churn. As we do not require a long-term service contract, our churn percentage is expected to be higher than traditional wireless carriers that require customers to sign a one- to two-year contract with significant early termination fees. Average monthly churn represents (a) the number of customers who have been disconnected from our system during the measurement period less the number of customers who have reactivated service, divided by (b) the sum of the average monthly number of customers during such period. We classify delinquent customers as churn after they have been delinquent for 30 days. In addition, when an existing customer establishes a new account in connection with the purchase of an upgraded or replacement phone and does not identify themselves as an existing customer, we count that phone leaving service as a churn and the new phone entering service as a gross customer addition. Churn for the year ended December 31, 2006 was 4.6% compared to 5.1% for the year ended December 31, 2005. Based upon a change in the allowable return period from 7 days to 30 days, we revised our definition of gross customer additions to exclude customers that discontinue service in the first 30 days of service. This revision reduces deactivations and gross customer additions commencing March 23, 2006, and reduces churn. Churn computed under the original 7 day allowable return period would have been 5.1% for the year ended December 31, 2006. Our average monthly rate of customer turnover, or churn, was 5.1% and 4.9% for the years ended December 31, 2005 and 2004, respectively. Average monthly churn rates for selected traditional wireless carriers ranges from 1.0% to 2.6% for post-pay customers and over 6.0% for pre-pay customers based on public filings or press releases.
     Average Revenue Per User. ARPU represents (a) service revenues less activation revenues, E-911, FUSF, and vendor’s compensation charges for the measurement period, divided by (b) the sum of the average monthly number of customers during such period. ARPU was $42.98 and $42.40 for the years ended December 31, 2006 and 2005, respectively, an increase of $0.58, or 1.4%. ARPU increased $1.27, or approximately 3.1%, during 2005 from $41.13 for the year ended December 31, 2004. The increase in ARPU was primarily the result of attracting customers to higher priced service plans, which include unlimited nationwide long distance for $40 per month as well as unlimited nationwide long distance and certain calling and data features on an unlimited basis for $45 per month.
     Cost Per Gross Addition. CPGA is determined by dividing (a) selling expenses plus the total cost of equipment associated with transactions with new customers less activation revenues and equipment revenues associated with transactions with new customers during the measurement period by (b) gross customer additions

during such period. Retail customer service expenses and equipment margin on handsets sold to existing customers when they are identified, including handset upgrade transactions, are excluded, as these costs are incurred specifically for existing customers. CPGA costs have increased to $117.58 for the year ended December 31, 2006 from $102.70 for the year ended December 31, 2005, which was primarily driven by the selling expenses associated with the launch of the Dallas/Ft. Worth metropolitan area, the Detroit metropolitan area and the expansion of the Tampa/Sarasota area to include the Orlando metropolitan area. In addition, on January 23, 2006, we revised the terms of our return policy from 7 days to 30 days, and as a result we revised our definition of gross customer additions to exclude customers that discontinue service in the first 30 days of service. This revision, commencing March 23, 2006, reduces deactivations and gross customer additions and increases CPGA. CPGA decreased $1.08, or 1.0%, in 2005 from $103.78 for the year ended December 31, 2004. The decrease in CPGA was the result of the higher rate of growth in customer activations and the relatively fixed nature of the expenses associated with those activations.
     Cost Per User. CPU is cost of service and general and administrative costs (excluding applicable non-cash stock-based compensation expense included in cost of service and general and administrative expense) plus net loss on handset equipment transactions unrelated to initial customer acquisition (which includes the gain or loss on sale of handsets to existing customers and costs associated with handset replacements and repairs (other than warranty costs which are the responsibility of the handset manufacturers)), divided by sum of the average monthly number of customers during such period. CPU for the years ended December 31, 2006 and 2005 was $19.65 and $19.57, respectively. CPU for the year ended December 31, 2004 was $18.95. We continue to achieve cost benefits due to the increasing scale of our business. However, these benefits have been offset by a combination of the construction and launch expenses associated with our Expansion Markets, which contributed approximately $3.42 of additional CPU for the year ended December 31, 2006. In addition, CPU has increased historically due to costs associated with higher ARPU service plans such as those related to unlimited nationwide long distance. During the years ended December 31, 2004 and 2005, CPU was impacted by substantial legal and accounting expenses in the amount of approximately $1.5 million and $5.9 million, respectively, associated with an internal investigation related to material weaknesses in our internal control over financial reporting as well as financial statement audits related to our restatement efforts.

(1)   On January 23, 2006, we revised the terms of our return policy from 7 days to 30 days, and as a result we revised our definition of gross customer additions to exclude customers that discontinue service in the first 30 days of service. This revision, commencing March 23, 2006, reduces deactivations and gross customer additions, which reduces churn and increases CPGA. Churn computed under the original 7 day allowable return period would have been 4.5%, 5.2%, 5.7% and 5.0% for the three month periods ended March 31, 2006, June 30, 2006, September 30, 2006 and December 31, 2006, respectively. CPGA computed under the original 7 day allowable return period would have been $105.33, $113.11, $110.43 and $113.67 for the three month periods ended March 31, 2006, June 30, 2006, September 30, 2006 and December 31, 2006, respectively.

These increases are primarily attributable to the continued demand for our service offering.
     Adjusted EBITDA. Adjusted EBITDA is presented in accordance with SFAS No. 131 as it is the primary performance metric for which our reportable segments are evaluated and it is utilized by management to facilitate evaluation of our ability to meet future debt service, capital expenditures and working capital requirements and to fund future growth. For the year ended December 31, 2006, Core Markets Adjusted EBITDA was $492.8 million compared to $316.6 million for the year ended December 31, 2005. For the year ended December 31, 2004, Core Markets Adjusted EBITDA was $203.6 million. We continue to experience increases in Core Markets Adjusted EBITDA as a result of continued customer growth and cost benefits due to the increasing scale of our business in the Core Markets.
     Adjusted EBITDA as a Percent of Service Revenues. Adjusted EBITDA as a percent of service revenues is calculated by dividing Adjusted EBITDA by total service revenues. Core Markets Adjusted EBITDA as a percent of service revenues for the year ended December 31, 2006 and 2005 was 43% and 36%, respectively. Core Markets Adjusted EBITDA as a percent of service revenues for the year ended December 31, 2004 was 33%. Consistent with the increase in Core Markets Adjusted EBITDA, we continue to experience corresponding increases in Core Markets Adjusted EBITDA as a percent of service revenues due to the growth in service revenues as well as cost benefits due to the increasing scale of our business in the Core Markets.

        $ (22,090 )   $ (97,214 )
     Customers. Net customer additions in our Expansion Markets were 587,072 for the year ended December 31, 2006. Total customers were 640,028 as of December 31, 2006 compared to 52,956 for the year ended December 31, 2005. The increase in customers was primarily attributable to the launch of the Dallas/Ft. Worth metropolitan area in March 2006, the Detroit metropolitan area in April 2006 and the expansion of the Tampa/Sarasota area to include the Orlando metropolitan area in November 2006. Net customer additions in our Expansion Markets were 52,956 for the year ended December 31, 2005, which was attributable to the launch of the Tampa/Sarasota metropolitan area in October 2005.
     Adjusted EBITDA (Deficit). Adjusted EBITDA is presented in accordance with SFAS No. 131 as it is the primary performance metric for which our reportable segments are evaluated and it is utilized by management to facilitate evaluation of our ability to meet future debt service, capital expenditures and working capital requirements and to fund future growth. For the year ended December 31, 2006, Expansion Markets Adjusted EBITDA deficit was $97.2 million compared to $22.1 million for the year ended December 31, 2005. The increases in Adjusted EBITDA deficit, when compared to the same periods in the previous year, were attributable to the launch of the Tampa/Sarasota metropolitan area in October 2005, the Dallas/Ft. Worth metropolitan area in March 2006, the Detroit metropolitan area in April 2006 and the expansion of the Tampa/Sarasota area to include the Orlando metropolitan area in November 2006 as well as expenses associated with the construction of the Los Angeles metropolitan area.

Reconciliation of Non-GAAP Financial Measures
     We utilize certain financial measures and key performance indicators that are not calculated in accordance with GAAP to assess our financial and operating performance. A non-GAAP financial measure is defined as a numerical measure of a company’s financial performance that (i) excludes amounts, or is subject to adjustments that have the effect of excluding amounts, that are included in the comparable measure calculated and presented in accordance with GAAP in the statement of income or statement of cash flows; or (ii) includes amounts, or is subject to adjustments that have the effect of including amounts, that are excluded from the comparable measure so calculated and presented.
     Average revenue per user, or ARPU, cost per gross addition, or CPGA, and cost per user, or CPU, are non-GAAP financial measures utilized by our management to judge our ability to meet our liquidity requirements and to evaluate our operating performance. We believe these measures are important in understanding the performance of our operations from period to period, and although every company in the wireless industry does not define each of these measures in precisely the same way, we believe that these measures (which are common in the wireless industry) facilitate key liquidity and operating performance comparisons with other companies in the wireless industry. The following tables reconcile our non-GAAP financial measures with our financial statements presented in accordance with GAAP.

     ARPU — We utilize average revenue per user, or ARPU, to evaluate our per-customer service revenue realization and to assist in forecasting our future service revenues. ARPU is calculated exclusive of activation revenues, as these amounts are a component of our costs of acquiring new customers and are included in our calculation of CPGA. ARPU is also calculated exclusive of E-911, FUSF and vendor’s compensation charges, as these are generally pass through charges that we collect from our customers and remit to the appropriate government agencies.
     Average number of customers for any measurement period is determined by dividing (a) the sum of the average monthly number of customers for the measurement period by (b) the number of months in such period. Average monthly number of customers for any month represents the sum of the number of customers on the first day of the month and the last day of the month divided by two. The following table shows the calculation of ARPU for the periods indicated.

     CPGA — We utilize cost per gross customer addition, or CPGA, to assess the efficiency of our distribution strategy, validate the initial capital invested in our customers and determine the number of months to recover our customer acquisition costs. This measure also allows us to compare our average acquisition costs per new customer to those of other wireless broadband PCS providers. Activation revenues and equipment revenues related to new customers are deducted from selling expenses in this calculation as they represent amounts paid by customers at the time their service is activated that reduce our acquisition cost of those customers. Additionally, equipment costs associated with existing customers, net of related revenues, are excluded as this measure is intended to reflect only the acquisition costs related to new customers. The following table reconciles total costs used in the calculation of CPGA to selling expenses, which we consider to be the most directly comparable GAAP financial measure to CPGA.

selling cash expenses associated with ongoing business operations on a per customer basis, to track changes in these non-selling cash costs over time, and to help evaluate how changes in our business operations affect non-selling cash costs per customer. In addition, CPU provides management with a useful measure to compare our non-selling cash costs per customer with those of other wireless providers. We believe investors use CPU primarily as a tool to track changes in our non-selling cash costs over time and to compare our non-selling cash costs to those of other wireless providers. Other wireless carriers may calculate this measure differently. The following table reconciles total costs used in the calculation of CPU to cost of service, which we consider to be the most directly comparable GAAP financial measure to CPU.

Liquidity and Capital Resources
     Our principal sources of liquidity are our existing cash, cash equivalents and short-term investments, cash generated from operations, proceeds from our recent sale of senior notes and our senior secured credit facility. At December 31, 2006, we had a total of approximately $552.1 million in cash, cash equivalents and short-term investments. We believe that our existing cash, cash equivalents and short-term investments, proceeds from our currently pending initial public offering, and our anticipated cash flows from operations will be sufficient to fully fund our projected operating and capital requirements for our existing business, currently planned expansion, planned enhancements of network capacity and upgrades for EVDO Revision A with VoIP, and service of our debt incurred in November 2006 through at least December 31, 2009.
     Our strategy has been to offer our services in major metropolitan areas and their surrounding areas, which we refer to as clusters. We are seeking opportunities to enhance our current market clusters and to provide service in new geographic areas. From time to time, we may purchase spectrum and related assets from third parties or the FCC. We participated as a bidder in FCC Auction 66 and in November 2006 we were granted eight licenses for a total aggregate purchase price of approximately $1.4 billion. See “Business — Auction 66 Markets.”
     As a result of the acquisition of the spectrum licenses from Auction 66 and the opportunities that these licenses provide for us to expand our operations into major metropolitan markets, we will require significant additional capital in the future to finance the construction and initial operating costs associated with such licenses, including clearing costs associated with non-governmental incumbent licenses which we currently estimate to be between approximately $40 million and $60 million. We generally do not intend to commence the construction of any individual license area until we have sufficient funds available to provide for the related construction and operating costs associated with such license area. We currently plan to focus on building out approximately 40 million of the total population in our Auction 66 Markets with a primary focus on the New York, Philadelphia, Boston and Las Vegas metropolitan areas. Of the approximate 40 million total population, we are targeting launch of operations with an initial covered population of approximately 30 to 32 million by late 2008 or early 2009. Total estimated capital expenditures to the launch of these operations are expected to be between $18 and $20 per covered population which equates to a total capital investment of approximately $550 million to $650 million. Total estimated expenditures, including capital expenditures, to become free cash flow positive, defined as Adjusted EBITDA less capital expenditures, are expected to be approximately $29 to $30 per covered population, which equates to $875 million to $1.0 billion based on an estimated initial covered population of approximately 30 to 32 million. We believe that our existing cash, cash equivalents and short-term investments, proceeds from our currently pending initial public offering, and our anticipated cash flows from operations will be sufficient to fully fund this planned expansion. Moreover, we have made no commitments for capital expenditures and we have the ability to reduce the rate of capital expenditure deployment.
     The construction of our network and the marketing and distribution of our wireless communications products and services have required, and will continue to require, substantial capital investment. Capital outlays have included license acquisition costs, capital expenditures for construction of our network infrastructure, costs associated with clearing and relocating non-governmental incumbent licenses, funding of operating cash flow losses incurred as we launch services in new metropolitan areas and other working capital costs, debt service and financing fees and expenses. Our capital expenditures for 2006 were approximately $550.7 million and aggregate capital expenditures for 2005 were approximately $266.5 million. These expenditures were primarily associated with the construction of the network infrastructure in our Expansion Markets and our efforts to increase the service area and capacity of our existing Core Markets network through the addition of cell sites and switches. We believe the increased service area and capacity in existing markets will improve our service offering, helping us to attract additional customers and increase revenues. In addition, we believe our new Expansion Markets have attractive demographics which will result in increased revenues.
     In connection with our payment of the purchase price for the Auction 66 licenses in October 2006, certain of our subsidiaries borrowed $1.25 billion under a secured bridge credit facility and an additional $250 million under a unsecured bridge credit facility. See “— Bridge Credit Facilities” below. The funds borrowed under the bridge credit facilities were used primarily to pay the aggregate purchase price of approximately $1.4 billion for the licenses we purchased in Auction 66. In November 2006, we consummated the sale of $1.0 billion in aggregate principal amount of 91/4% senior notes and entered into a senior secured credit facility, pursuant to which we may borrow up to $1.7 billion. We borrowed $1.6 billion under our senior secured credit facility concurrently with the closing of the sale of the 91/4% senior notes and used the amount borrowed, together with the net proceeds from the

Table of Contents

sale of the 91/4% senior notes, to repay all amounts owed under the first and second lien credit agreements and the secured and unsecured bridge credit facilities and to pay the related premiums, fees and expenses and we intend to use the remaining amounts for general corporate purposes. As of December 31, 2006, we owed an aggregate of approximately $2.6 billion under our senior secured credit facility and 91/4% Senior Notes. On February 20, 2007, MetroPCS Wireless, Inc. entered into an amendment to the senior secured credit facility. Under the amendment, the margin used to determine the senior secured credit facility interest rate was reduced to 2.25% from 2.50%.
     Our senior secured credit facility calculates consolidated Adjusted EBITDA as: consolidated net income plus depreciation and amortization; gain (loss) on disposal of assets; non-cash expenses; gain (loss) on extinguishment of debt; provision for income taxes; interest expense; and certain expenses of MetroPCS Communications minus interest and other income and non-cash items increasing consolidated net income.
     We consider Adjusted EBITDA, as defined above, to be an important indicator to investors because it provides information related to our ability to provide cash flows to meet future debt service, capital expenditures and working capital requirements and fund future growth. We present this discussion of Adjusted EBITDA because covenants in our senior secured credit facility contain ratios based on this measure. If our Adjusted EBITDA were to decline below certain levels, covenants in our senior secured credit facility that are based on Adjusted EBITDA, including our maximum senior secured leverage ratio covenant, may be violated and could cause, among other things, an inability to incur further indebtedness and in certain circumstances a default or mandatory prepayment under our senior secured credit facility. Our maximum senior secured leverage ratio is required to be less than 4.5 to 1.0 based on Adjusted EBITDA plus the impact of certain new markets. The maximum senior secured leverage ratio is calculated as the ratio of senior secured indebtedness to Adjusted EBITDA, as defined by our senior secured credit facility. For the year ended December 31, 2006, our senior secured leverage ratio was 3.24 to 1.0. In addition, consolidated Adjusted EBITDA is also utilized, among other measures, to determine management’s compensation levels. Adjusted EBITDA is not a measure calculated in accordance with GAAP, and should not be considered a substitute for, operating income (loss), net income (loss), or any other measure of financial performance reported in accordance with GAAP. In addition, Adjusted EBITDA should not be construed as an alternative to, or more meaningful than cash flows from operating activities, as determined in accordance with GAAP.
     The following table shows the calculation of our consolidated Adjusted EBITDA, as defined in our senior secured credit facility, for the years ended December 31, 2004, 2005 and 2006.

     In connection with the closing of the sale of the 91/4% senior notes, the entry into our senior secured credit facility and the repayment of all amounts outstanding under our first and second lien credit agreements and secured and unsecured bridge credit facilities, we consummated a concurrent restructuring transaction. As a result of the restructuring transaction, MetroPCS Wireless, Inc. became a wholly-owned direct subsidiary of MetroPCS, Inc. (formerly MetroPCS V, Inc.), which is a wholly-owned direct subsidiary of MetroPCS Communications, Inc. MetroPCS Communications, Inc. and MetroPCS, Inc. guaranteed the 91/4% senior notes and the obligations under the senior secured credit facility. MetroPCS, Inc. also pledged the capital stock of MetroPCS Wireless, Inc. as security for the obligations under the senior secured credit facility. All of our FCC licenses and our 85% limited liability company member interest in Royal Street Communications are now held by MetroPCS Wireless, Inc. and its wholly-owned subsidiaries.
Operating Activities
     Cash provided by operating activities was $364.8 million during the year ended December 31, 2006 compared to $283.2 million for the year ended December 31, 2005. The increase was primarily attributable to the timing of payments on accounts payable and accrued expenses for the year ended December 31, 2006 as well as an increase in deferred revenues due to an approximately 53% increase in customers during the year ended December 31, 2006 compared to the year ended December 31, 2005.
     Cash provided by operating activities was $283.2 million during the year ended December 31, 2005 compared to cash provided by operating activities of $150.4 million during the year ended December 31, 2004. The increase was primarily attributable to a significant increase in net income, including a $228.2 million gain on the sale of a 10 MHz portion of our 30MHz PCS license for the San Francisco — Oakland — San Jose basic trading area, and the timing of payments on accounts payable and accrued expenses in the year ended December 31, 2005, partially offset by interest payments on the Credit Agreements that were executed in May 2005.
     Cash provided by operating activities was $150.4 million during the year ended December 31, 2004 compared to cash provided by operating activities of $112.6 million during the year ended December 31, 2003. The increase was primarily attributable to an increase in the net income, partially offset by an increase of $66.1 million used in cash due to changes in working capital compared to the year ended December 31, 2003. This increase is primarily due to increases in inventories and the timing of payments on accounts payable and accrued expenses.
Investing Activities
     Cash used in investing activities was $1.9 billion during the year ended December 31, 2006 compared to $905.2 million during the year ended December 31, 2005. The increase was due primarily to a $887.7 million increase in purchases of FCC licenses and a $284.3 million increase in purchases of property and equipment, partially offset by a $355.5 million decrease in net purchases of investments.
     Cash used in investing activities was $905.2 million during the year ended December 31, 2005 compared to $190.9 million during the year ended December 31, 2004. This increase was due primarily to a $416.9 million increase in the purchase of FCC licenses, an increase in purchases of investments in the amount of $580.8 million,

84


Table of Contents

and a $27.5 million increase in purchases of property and equipment, partially offset by proceeds of $230.0 million from the sale of a 10 MHz portion of our 30 MHz PCS license for the San Francisco-Oakland-San Jose basic trading area.
     Cash used in investing activities was $190.9 million during the year ended December 31, 2004, compared to $306.9 million for the year ended December 31, 2003. The decrease during 2004 is primarily attributable to a $284.6 million increase in proceeds from the sale and maturity of investments, as well as a $50.5 million decrease in the purchases of investments, partially offset by an increase in purchases of property and equipment in the amount of $133.1 million.
Financing Activities
     Cash provided by financing activities was $1.6 billion for the year ended December 31, 2006 compared to $712.2 million for the year ended December 31, 2005. The increase was due primarily to net proceeds from the senior secured credit facility and the 91/4% senior notes.
     Cash provided by financing activities during the year ended December 31, 2005 was $712.2 million, compared to cash used in financing activities of $5.4 million for the year ended December 31, 2004. The increase during 2005 is mainly attributable to proceeds from borrowings under our Credit Agreements of $902.9 million as well as net proceeds from the issuance of Series E Preferred Stock in the amount of $46.7 million. These proceeds are partially offset by various transactions including repayment of the FCC notes in the amount of $33.4 million, repayment of the Senior Notes in the amount of $178.9 million, which included a premium of $28.9 million, and payment of debt issuance costs in the amount of $29.5 million.
     Cash used in financing activities during the year ended December 31, 2004 was $5.4 million, compared to cash provided by financing activities of $201.9 million for the year ended December 31, 2003. During 2003, we had net proceeds of $145.5 million from the issuance of our 103/4% Senior Notes and $65.5 million from the issuance of Series D Preferred Stock, which are the primary reasons for the decrease in cash provided by financing activities in 2004.
First and Second Lien Credit Agreements
     On November 3, 2006, we paid the lenders under the first and second lien credit agreements $931.5 million plus accrued interest of $8.6 million to extinguish the aggregate outstanding principal balance under the first and second lien credit agreements. As a result, we recorded a loss on extinguishment of debt in the amount of approximately $42.7 million.
     On November 21, 2006, we terminated the interest rate cap agreement that was required by our first and second lien credit agreements. We received approximately $4.3 million upon termination of the agreement. The proceeds from the termination of the agreement approximated its carrying value.
Bridge Credit Facilities
     In July 2006, MetroPCS II, Inc., or MetroPCS II, an indirect wholly-owned subsidiary of MetroPCS Communications, Inc. (which has since merged into MetroPCS Wireless, Inc.), entered into an Exchangeable Senior Secured Credit Agreement and Guaranty Agreement, dated as of July 13, 2006, or the secured bridge credit facility. The aggregate credit commitments available under the secured bridge credit facility were $1.25 billion and were fully funded.
     On November 3, 2006, MetroPCS II repaid the aggregate outstanding principal balance under the secured bridge credit facility of $1.25 billion and accrued interest of $5.9 million. As a result, MetroPCS II recorded a loss on extinguishment of debt of approximately $7.0 million.
     In October 2006, MetroPCS IV, Inc., an indirect wholly-owned subsidiary of MetroPCS Communications, Inc. (which has since merged into MetroPCS Wireless, Inc.), entered into an additional Exchangeable Senior Unsecured Bridge Credit Facility, or the unsecured bridge credit facility. The aggregate credit commitments available under the unsecured bridge credit facility were $250 million and were fully funded.

85


Table of Contents

     On November 3, 2006, MetroPCS IV, Inc. repaid the aggregate outstanding principal balance under the unsecured bridge credit facility of $250.0 million and accrued interest of $1.2 million. As a result, MetroPCS IV, Inc. recorded a loss on extinguishment of debt of approximately $2.4 million.
Senior Secured Credit Facility
     MetroPCS Wireless, Inc., an indirect wholly-owned subsidiary of MetroPCS Communications, Inc., entered into the senior secured credit facility on November 3, 2006. The senior secured credit facility consists of a $1.6 billion term loan facility and a $100 million revolving credit facility. The term loan facility is repayable in quarterly installments in annual aggregate amounts equal to 1% of the initial aggregate principal amount of $1.6 billion. The term loan facility will mature seven years following the date of its execution in November 2006. The revolving credit facility will mature five years following the date of its execution in November 2006.
     The facilities under the senior secured credit agreement are guaranteed by MetroPCS Communications, Inc., MetroPCS, Inc. and each of MetroPCS Wireless, Inc.’s direct and indirect present and future wholly-owned domestic subsidiaries. The facilities are not guaranteed by Royal Street or its subsidiaries, but MetroPCS Wireless, Inc. has pledged the promissory note given by Royal Street in connection with amounts borrowed by Royal Street from MetroPCS Wireless, Inc. and we pledged the limited liability company member interests we hold in Royal Street. The senior secured credit facility contains customary events of default, including cross defaults. The obligations are also secured by the capital stock of MetroPCS Wireless, Inc. as well as substantially all of the present and future assets of MetroPCS Wireless, Inc. and each of its direct and indirect present and future wholly-owned subsidiaries (except as prohibited by law and certain permitted exceptions).
     Under the senior secured credit agreement, MetroPCS Wireless, Inc. will be subject to certain limitations, including limitations on its ability to incur additional debt, make certain restricted payments, sell assets, make certain investments or acquisitions, grant liens and pay dividends. MetroPCS Wireless, Inc. is also subject to certain financial covenants, including maintaining a maximum senior secured consolidated leverage ratio and, under certain circumstances, maximum consolidated leverage and minimum fixed charge coverage ratios. There is no prohibition on our ability to make investments in or loan money to Royal Street.
     Amounts outstanding under our senior secured credit facility bear interest at a LIBOR rate plus a margin as set forth in the facility and the terms of the senior secured credit facility require us to enter into interest rate hedging agreements that fix the interest rate in an amount equal to at least 50% of our outstanding indebtedness, including the notes.
     On November 21, 2006, MetroPCS Wireless, Inc. entered into a three-year interest rate protection agreement to manage its interest rate risk exposure and fulfill a requirement of its senior secured credit facility. The agreement covers a notional amount of $1.0 billion and effectively converts this portion of MetroPCS Wireless, Inc.’s variable rate debt to fixed rate debt at an annual rate of 7.419%. The quarterly interest settlement periods begin on February 1, 2007. The interest rate protection agreement expires on February 1, 2010.
     On February 20, 2007, MetroPCS Wireless, Inc. entered into an amendment to the senior secured credit facility. Under the amendment, the margin used to determine the senior secured credit facility interest rate was reduced to 2.25% from 2.50%.
