Our Business Strategy

Our strategy is to provide transformative broadband solutions for critical infrastructure industries and enterprises including private wireless connectivity on 900 MHz spectrum and next-generation communications platforms. We support digital transformations, infrastructure modernization, and cybersecurity strategies that will enable the new standard for security, performance and safety. Leveraging our solutions, critical infrastructure customers can tackle their most impactful opportunities, unlocking applications from analytics to automation to edge monitoring and artificial intelligence. Together with Anterix, customers can build solutions that will scale and evolve with their business needs. To that end, we are pursuing a two-pronged strategy focused on: (i) converting our nationwide narrowband 900 MHz spectrum position into valuable broadband spectrum; and (ii) offering long-term leasing of broadband spectrum or other creative solutions in complex system areas to monetize spectrum coupled with platform services and solutions to utility and critical infrastructure enterprises nationwide.

Our Spectrum Assets

Our spectrum is our most valuable owned asset. We hold licenses nationwide, over 51% of the 900 MHz band in the United States. However, where spectrum is the highest priced, the top 20 metropolitan market areas in the United States which cover approximately 38% of the U.S. population, we hold on average more than 6 MHz worth of spectrum. We acquired the majority of our 900 MHz spectrum and certain related equipment from Sprint in September 2014.

In the 900 MHz band, the FCC historically allocated approximately 10 MHz of spectrum, sub-divided into 40 10-channel blocks (for a total of 399 contiguous channels) alternating between blocks designated for the operation of SMR commercial systems and blocks designated for B/ILT, with the FCC’s rules also enabling B/ILT licenses to be converted to SMR use. Subsequently, the FCC conducted overlay auctions on the SMR designated blocks that awarded geographic-based licenses on an MTA basis while affording operational protection to incumbent, site-based licensees in those areas. Certain MTA licenses were not purchased at auction and have been returned to the FCC. In addition, the FCC never auctioned the 20 blocks of B/ILT spectrum in some parts of the United States. The licensees acquired site-based licenses utilizing this spectrum through the initial application and coordination procedure, which has been frozen since 2017. As a result, the FCC is currently holding over 27% of 900 MHz narrowband spectrum in its inventory throughout the United States.

Broadband licenses

As of March 31, 2025, we were cumulatively granted by the FCC broadband licenses for 194 counties, inclusive of licenses transferred. As a result, we relinquished to the FCC our narrowband licenses and if necessary made the Anti-Windfall Payments for the same 194 counties, as required by the Report and Order.

Converting our Nationwide Narrowband 900 MHz Spectrum Position to Broadband

Converting our spectrum from narrowband to broadband licenses nationwide is a foundational component of our two-pronged strategy as it provides the underpinning for achieving our business strategy. To achieve this conversion, we are focused on intentionally clearing incumbents out of the broadband license segment and obtaining broadband licenses in counties (i) in which we have customer contracts, (ii) where we believe we have near-term commercial prospects, or (iii) that may be strategically advantageous to achieve optimum costs for broadband licenses over time.

Secure Broadband Licenses

In the Report and Order, the FCC chose to make counties the “base unit of measure” for calculating whether an entity is eligible to hold a broadband license. As a result of this decision and our extensive accumulated spectrum holdings, Anterix—and only Anterix—is an essential party in every one of the nation’s 3,233 counties. And while we intend to continue to prioritize our spectrum transactions in areas where we have customer opportunities, we also plan to pursue spectrum transactions opportunistically to recognize a positive return on our investments in spectrum clearing costs. We have been proactive in this effort and to date have completed, and intend to continue to pursue spectrum transactions to support our efforts to satisfy the broadband license eligibility requirements.

Clear Covered Incumbents

We have been proactive in our clearing efforts in preparation for the broadband licensing process. Our dedicated clearing team is focused on negotiating agreements to move Covered Incumbents from the broadband segment of the 900 MHz spectrum band to the segments allocated for continued narrowband operations within the 900 MHz band or out of 900 MHz band entirely. Our team has worked with Covered Incumbents and negotiated and contracted approximately three quarters of the transactions required, inclusive of five Complex Systems, to clear the licensed 900 MHz Broadband Segment channels.

Deploying our Commercial Business Offering

With the initial Report and Order completed and the work we have done since then to pave the way for the deployment of broadband in the 900 MHz band, we have moved into the second key prong of our strategy of establishing our commercial position and accelerating adoption of our principal commercial business offering. We are implementing this strategy through:

•targeted outreach and education by our sales, marketing, business development, commercial operations and industry government affairs organizations;

•participating in the Utilities Broadband Alliance (“UBBA”), other industry associations and industry events;

•attracting vendors to the Anterix Active Ecosystem (“AAE”);

•advancing our Utility Strategic Advisory Board (“USAB”); and

•launching our AnterixAcceleratorTM initiative.

The UBBA membership currently includes 38 electric utilities and subsidiaries among its over 100 members. The AAE targets our Nation’s electric grid innovators and includes participation of over 125 innovative technology companies that provide deployment and application solutions for private broadband. We launched the AAE to foster, strengthen, and expand the landscape of 900 MHz devices, services and solutions. Participation from the broad range of technology innovators can bring extensive value to utilities and other critical infrastructure providers who deploy PLTE. Our USAB is composed of executives from both current and prospective utility customers, offering strategic guidance on issues where we can harness collective action to benefit their respective organizations, especially through the AAE, and other strategic initiatives.

The primary intent of our business is to lease the broadband licenses we secure to customers for long-term leases (generally 20 years or longer) containing additional long-term renewal options. Based upon our analysis and discussions with current and potential customers to date, we are seeing strong and growing indications of Demonstrated Intent for PLTE networks using 900 MHz spectrum. To fulfill our business offering, we will be responsible for the costs of securing the broadband licenses from the FCC, including the costs of clearing and meeting the broadband eligibility requirements. By contrast, we expect that most of our customers will bear the costs of deploying and operating their private broadband networks, technologies and solutions. And, beyond our principal commercial business offering, we are also exploring additional opportunities to offer electric utility companies additional value-added solutions and services to support their network deployments and operations, and grid modernization initiatives.

Accordingly, our approach to driving the second key prong of our strategy includes: 1) advancing our potential customers through the pipeline by assisting them with their decisions and evaluation process of private wireless networks; 2)

encouraging federal and state agencies to support the investment and deployment of PLTE solutions in the 900 MHz band by utilities and critical infrastructure companies; 3) participating in demonstrations and tests with laboratories such as National Renewable Energy Lab (“NREL”), Pacific Northwest National Lab and National Institute of Standards and Technology (“NIST”) to validate the benefits of PLTE systems; 4) developing expanded value-added business offerings; 5) enabling and growing the AAE; 6) participating in UBBA and other relevant industry associations to promote our solution; and 7) continually evaluating potential opportunities to expand the application of private wireless broadband networks built on 900 MHz Broadband Spectrum.

Further, we have launched the AnterixAcceleratorTM, our new industry engagement initiative to address and speed up the time to realization of value for us and our customers by allowing them to move quickly to deploy 900 MHz private wireless broadband networks. This initiative will include a significant review of pricing, payment and ownership terms as well as the potential for collaboration with strategic partners on additional products and services with AAE.

Continue to Build the Customer Pipeline

Our sales and support teams are actively working with many of the largest Investor-Owned Utilities (“IOU”). More specifically, these teams are working in coordination with representatives from our target customers, LTE infrastructure vendors, end-user device manufacturers, system integrators and other technology companies in addition to responding to Requests for Information (“RFI”), Requests for Proposals (“RFP”) and requests to support technology trials related to using our 900 MHz spectrum for broadband services. Currently, there are three experimental licenses granted to noncustomer utilities and three experimental licenses granted to other vendors and labs to showcase and promote 900 MHz Broadband Spectrum.

Build Support with Federal and State Agencies

The vast majority of our targeted critical infrastructure customers are highly regulated by both federal and state agencies. Electric utilities, for example, may be regulated by the Federal Energy Regulatory Commission, the Public Utilities Commissions within the states they serve and/or other state and municipal governance or regulatory bodies. Other agencies that guide utility regulations include the Department of Energy, the Department of Homeland Security, and NIST, as well as regional transmission organizations and independent system operators. We are working with each of these agencies to educate them about the security, reliability and priority access benefits that private broadband wireless networks, technologies and solutions can offer to utilities. We are also working with a number of state agencies and commissions who regulate electric utilities and have a strong influence over electric utility investment decisions. Our goal with these stakeholders is to ensure they have the right information and are properly educated on the immense benefits of utility-scale private wireless broadband networks for end-use customers so they can confidently approve investments made by utilities including the costs of procuring our spectrum assets and deploying private broadband LTE networks, technologies and solutions into their respective rate making filings. Their understanding and appreciation that utility control of communications for grid modernization programs enhances the utilities’ ability to provide safe, secure, reliable and resilient electricity for ratepayers is essential. When included in rate bases, utilities are permitted to recover costs and earn a customary rate of return on these prudent investments.

Develop a Roadmap for Expanded Services

Through our day-to-day interactions with prospective utility and critical infrastructure customers, and our responses and subsequent discussions related to RFIs and RFPs, we have identified additional areas of opportunity to support our current and prospective customers in the implementation and operation of PLTE networks. We are performing due diligence to determine how best to meet these customer needs, including using our internal expertise, collaborating with industry partners and working with specific service providers.

Identify and Evaluate New Opportunities for Our Spectrum

The wireless communications industry is highly competitive and subject to rapid regulatory, technological and market changes. A key part of our business strategy is to continually monitor changes in the wireless industry and to evaluate how these changes could enable us to maximize the value of our spectrum assets. Additionally, although we are initially focusing on the electric utility industry, we have identified other customer groups, including ports, railroads, water, oil and gas facilities, and mining operations, where we believe there is both customer demand and a good fit for the private wireless broadband networks, technologies, and solutions that our spectrum assets could support. As proof of the potential demand for and value of our spectrum assets, two of the most recent FCC broadband spectrum auctions exceeded consensus valuation estimates and brought in the first and third highest auction proceeds ever for the U.S. Treasury. Additionally, T-Mobile agreed to purchase 600 MHz broadband spectrum from entities that hold broadband spectrum licenses for values that far exceeded the price paid for these broadband spectrum licenses at FCC auction, which we believe demonstrates the continued demand for licensed broadband spectrum.

Enable the Anterix Active Ecosystem with U.S. Band 8

Our spectrum assets are located in the international 3GPP global standard Band 8 channel which is a frequency division duplex pair assigned to the 880 - 915 / 925 - 960 MHz spectrum bands. This pairing is aligned for use with both 4G and 5G technologies and is currently being utilized with commercial LTE and 5G broadband networks globally in Asia, Europe, and other parts of the world. Our efforts are ongoing to facilitate continued adoption of 900 MHz Band 8 radio access network equipment and end-user devices in the U.S. by working with chipmakers and module and device vendors to help ensure that customers who deploy 900 MHz for private wireless networks have timely access to 3GPP standards-compliant Band 8 devices that meet the technical operating specifications established in the FCC’s Report and Order. We also worked with an FCC certification testing lab to develop testing protocols to enable quick certification of devices for use in the United States. The benefit of working with a global standard is that many existing devices, network components, and solutions are well suited for the working environment of our targeted critical infrastructure and enterprise customers. Global standards also provide an LTE path for technology, ensuring forward and backward compatibility, all these benefits therefore extend to Anterix customers. Additionally, we successfully led and completed initiatives in 3GPP to secure enhancements to the US 900 MHz spectrum to benefit our customers, including the designation of a new band, both for LTE and 5G, which received worldwide wireless industry support. 3GPP has approved and incorporated Band 106 and n106 in its specifications, designated for LTE and 5G respectively, as a subset of Band 8 in the US.

Our Broadband Market Opportunity

We have currently identified utility and critical infrastructure enterprises as the primary customers for our current and future broadband spectrum assets. We have identified the electric utility industry as our initial focused customer group. We believe that security, priority access, latency, redundancy, private ownership, control and unique coverage requirements are just some of the reasons utility and critical infrastructure enterprises would be interested in obtaining rights to deploy the private wireless broadband networks, technologies and solutions that can be enabled through use of our licensed spectrum.

The electric utility industry is undergoing a fundamental transformation. Grid modernization efforts and the drive to reduce carbon emissions have disrupted the need for utilities to build new large-scale, centralized facilities. Today, power is generated by smaller, more geographically distributed facilities that can switch from a power producer to a recipient of power generated by a variety of other disparate sources, including wind and solar installations. Grid architecture must now accommodate end-users that are both generators and consumers, converting back and forth rapidly and carrying power in both directions, something the existing grid was not originally designed to handle. Technological advancements have produced sensors and smart devices to enable the new two-way grid and offer operators the ability to control and run the grid efficiently, safely and reliably. The legacy communications systems utilized by many utilities have increasing interference and/or higher cyber threats, are not designed to handle this new data load, are inefficient and costly to maintain, and, in many cases, have associated equipment that is approaching end of life. The 900 MHz private wireless network allows utilities to have full control of the design, construction, and operation of their network. Utility mission-critical applications are prioritized, even in situations when other networks become overloaded or experience disruptions. Such control fosters heightened efficiency, resiliency, security, and responsiveness. This is more relevant than ever in light of recent extreme weather events.

Commercial Developments

We have invested in building our business development, sales, marketing and other support teams, which include both external and internal resources, to help foster our evolving customer relationships in furtherance of growing and maturing our pipeline. Since the FCC’s issuance of the Report and Order, our sales and marketing efforts have been focused on pursuing spectrum lease and sale arrangements, implementing creative spectrum solutions in markets where Complex Systems exist and introducing our integrated platform solutions to our targeted utility and critical infrastructure customers.

Our business development, sales and marketing organizations exercise the following three key methods to grow and mature our pipeline: (i) direct account-based sales and marketing efforts to our targeted customers; (ii) regulatory outreach and support; and (iii) industry trade organization collaboration. These efforts are enhanced with sales and marketing partnerships with a variety of third parties, such as integrators and technology and equipment vendors, with whom we will seek active promotion of our broadband spectrum assets and support for our broadband spectrum assets with their products, technologies, solutions and services. Additionally, our senior executives, engineering, technology, commercial operations and marketing teams support our sales efforts through presentations, branded participation through sponsorships and speaking engagements at major trade events, associations and organizations, customer meetings, collateral, and product demonstrations to expand our reach and brand awareness.

During the year ended March 31, 2025, we transferred to Oncor the 900 MHz Broadband Spectrum and the associated broadband licenses related to four counties and received a milestone payment of $34.0 million. This resulted in the recognition of a gain on the sale of spectrum and derecognition of the contingent liability associated with the transferred counties.

Motorola Lease

In 2014, we entered into an agreement with Motorola (the “2014 Motorola Spectrum Agreement”) to lease a portion of our 900 MHz licenses in exchange for an upfront, fully paid lease fee of $7.5 million and a $10 million investment in our subsidiary, PDV Spectrum Holding Company, LLC (the “Subsidiary”), which we formed to hold our 900 MHz spectrum licenses. Motorola’s investment in the Subsidiary was convertible, at the option of either party, into shares of our common stock at a price equal to $20.00 per share (the “Conversion Right”). In May 2022, Motorola exercised its Conversion Right, and we issued Motorola 500,000 shares of our common stock (the “Shares”) in conversion of Motorola’s ownership of 500,000 Class B Units (the “Units”) in our Subsidiary. In June 2022, we filed a Registration Statement on Form S-3 (File No. 333-265930) to register the 500,000 shares of our common stock held by Motorola for resale or other disposition by Motorola (the “Resale Registration Statement”). The Resale Registration Statement was declared effective by the SEC on July 15, 2022.

Motorola is not entitled to any profits, dividends, or other distribution from the operations of the Subsidiary. Under the terms of the 2014 Motorola Spectrum Agreement, Motorola can use the leased channels to provide narrowband services to certain qualified end-users. The end-users can only use the leased channels for their internal communication purposes. The end-users cannot sublease the channels to any other end-users or any commercial radio system operations or carriers. The 2014 Motorola Spectrum Agreement limits the total number of channels that Motorola can lease in any market area. It also provides us with flexibility regarding the future use and management of our spectrum, including relocation and repurposing policies designed to facilitate any necessary realignment of frequencies that may be associated with our efforts to clear spectrum for broadband uses.

As of December 31, 2024, we recognized all the revenue associated with the 2014 Motorola Spectrum Agreement.

Competition

Our competitors include spectrum holders, retail wireless network providers, such as Verizon, AT&T, T-Mobile, and EchoStar, private radio operators and other public and private companies, including potential new spectrum entrants who supply spectrum or other communication networks, technologies, products and solutions to our targeted utility and critical infrastructure entities. For example, in February 2025, T-Mobile announced that it has entered into an agreement to sell its 800 MHz spectrum holdings. The buyer of this spectrum has indicated it may make this spectrum available to our target utility customers. If the buyer of this spectrum does elect to lease or sell the 800 MHz spectrum it acquires from T-Mobile to our target customers, the resulting direct competition from this offering could reduce the number of agreements we can secure to lease or sell our spectrum and reduce the cost that potential customers are willing to pay to lease or acquire our spectrum, any of which would have a material adverse effect on our business, results of operations, financial condition and prospects.

Many of these competitors have a long track record of providing technologies, products and solutions to our targeted customers and have greater political and regulatory influence than we do. In addition, many of our competitors have more resources, substantially greater product development and marketing budgets, greater name and brand recognition, a significantly greater base of customers in which to spread their operating costs and more financial and personnel resources than we do. All of these factors could prevent, delay or increase the costs of commercializing the broadband licenses we secure to our targeted customers.

In addition, these and other competitors have developed or may develop services, technologies, products and solutions that directly compete with the broadband networks, technologies, products and solutions that can be deployed with our spectrum assets. If competitors offer services, technologies, products and solutions to our targeted customers at prices and terms that make the licensing of our spectrum assets unattractive, we may be unable to attract customers at prices or on terms that would be favorable, or at all, which could have an adverse effect on our financial results and prospects.

Further, the FCC and other federal, state and local governmental authorities could adopt new regulations or take actions, including making additional spectrum available that can be utilized by our targeted customers, which could harm our ability to license our spectrum assets. For example, the federal government created and funded the First Responder Network Authority (“FRNA”), which the federal government authorized to help accomplish, fund, and oversee the deployment of a dedicated Nationwide Public Safety Broadband Network (“NPSBN”), which is marketed as “FirstNet.” The NPSBN is an additional source of competition to utilizing our 900 MHz spectrum assets by our targeted utility and critical infrastructure enterprises.

Our FCC Initiatives

FCC 5 x 5 MHz proceeding

Joint Petition

On February 28, 2024, the Company, along with several interested parties, including major utilities, and trade associations, filed a Petition for Rulemaking (the “Petition”) with the FCC. The Petition seeks the FCC’s adoption of its previously considered expansion of the current paired 3 x 3 MHz broadband segment to a paired 5 x 5 MHz broadband segment at the 900 MHz band. On January 15, 2025, the FCC adopted the NPRM to expand the 900 MHz Broadband Segment. After the NPRM’s publication in the Federal Register, the FCC will seek comments and reply to comments in advance of a potential Report and Order. The expansion of the 900 MHz band to permit 5 x 5 MHz broadband will support growing demand for wide-area, private, and secure wireless broadband networks for utilities, critical infrastructure, and business enterprise entities, among other benefits.

The 900 MHz Report and Order

On May 13, 2020, the FCC approved the Report and Order to modernize and realign the 900 MHz band to increase its usability and capacity by allowing it to be utilized for the deployment of broadband networks, technologies and solutions. In the Report and Order, the FCC reconfigured the 900 MHz band to create a 6 MHz broadband segment (240 channels) and two narrowband segments, consisting of a 3 MHz narrowband segment (120 channels) and a 1 MHz narrowband segment (39 channels). FIGURE I below illustrates the FCC realignment as outlined in the Report and Order.

FIGURE I

The Role of the County

Under the Report and Order, the FCC established the “county” as the base unit of measure in determining whether a broadband applicant is eligible to secure a broadband license. There are 3,233 counties in the United States, including Puerto Rico and other U.S. territories.

Broadband License Eligibility Requirements

The Report and Order establishes three eligibility requirements to obtain broadband licenses in a county, which we refer to herein as (i) the “50% Licensed Spectrum Test,” (ii) the “90% Broadband Segment Test” and (iii) the “240 Channel Requirement.”

Treatment of Complex Systems

The Report and Order exempts Complex Systems from the Mandatory Retuning process, even when a broadband applicant meets the 90% Broadband Segment Test, because retuning these systems would potentially be disruptive to the operators. MAP 1 below illustrates the remaining seven current Complex Systems.

The Association of American Railroads

The nation’s railroads, particularly the major freight lines, operate on six narrowband 900 MHz channels licensed to their trade association, the Association of American Railroads (“AAR”). Three of these narrowband channels are located in the 900 MHz Broadband Segment created by the FCC. In January 2020, we entered into an agreement with the AAR in which we agreed to cancel licenses in the 900 MHz band to enable the AAR to relocate its operations, including operations utilizing the three channels located in the 900 MHz Broadband Segment (the “AAR Agreement”). The FCC referenced the AAR agreement in the Report and Order and required us to cancel our licenses in accordance with the AAR Agreement. We cancelled these licenses in June 2020. The FCC then modified the AAR license to provide the additional channels to enable the railroads to relocate their current operations. This modification to remove broadband segment channels is planned to be completed in 2025. The Report and Order also provides that the FCC will credit us for our cancelled licenses for purposes of determining our eligibility to secure broadband licenses and the calculation of any Anti-Windfall Payments.

Broadband Licensing Process

In May 2021, the FCC’s Wireless Telecommunication Bureau released a Public Notice detailing the application requirements and timeline for obtaining broadband licenses. The broadband licensing process includes filing an application with the FCC used for new wireless licenses, completing an Eligibility Certification and developing a Transition Plan describing the agreements the prospective broadband applicant has entered into with Covered Incumbents. We intend to pursue and file applications based on the timing of customer opportunities, strategic initiatives and our spectrum clearing results and shortly thereafter surrender our underlying licenses. The Anti-Windfall Payment to the U.S. Treasury for any spectrum we obtain from the FCC’s inventory to reach the 240 Channel Requirement will be made as soon as possible after the FCC provides us the amount due for these channels. In cases where we have satisfied the 90% Broadband Segment Test but have not reached an agreement with all Covered Incumbents, the Mandatory Retuning process will commence after we receive the broadband license.

1.50% Licensed Spectrum Test. To be eligible for a broadband license in a particular county, a broadband applicant must demonstrate that it holds more than 50% of the outstanding licensed channels in that county. As noted above, the 900 MHz band is made up of a maximum of 399 channels in each county. The FCC has licensed less than the maximum number of 399 channels in all but the most populous counties. Because the 50% Licensed Spectrum Test is based on licensed channels, any channels that are not licensed by the FCC are not included in the denominator when determining whether the broadband applicant has satisfied this test. As of the date of this filing, we alone satisfy the 50% Licensed Spectrum Test in approximately 3,200 counties of the 3,233 counties in the United States and its territories. MAP 2 below illustrates our licensed channels (including those pending applications with the FCC) by county in the entire 900 MHz band segment created by the Report and Order.

2.90% Broadband Segment Test. The second test, the 90% Broadband Segment Test, addresses the balance between a voluntary market process to clear any Covered Incumbent and the Mandatory Retuning process established by the FCC in the Report and Order (which applies to all Covered Incumbents, except for those Covered Incumbents operating Complex Systems. This test requires the broadband applicant to hold, have agreements with or protect Covered Incumbents equal to 90% or more of the licensed channels in the broadband segment in a particular county and within 70 miles of the county’s boundaries before the FCC will issue a broadband license. The broadband segment in the 900 MHz band has a total of 240 channels. The 90% Broadband Segment Test is calculated using outstanding licensed channels, which means that if the FCC has licensed all 240 channels, the broadband applicant would be required to have control of, or agreements covering, 216 channels within the broadband segment. In most counties in the United States, the FCC has licensed fewer than 240 channels in the broadband segment and these unlicensed channels are not included in the denominator when determining whether the broadband applicant has satisfied this 90% Broadband Segment Test.

A broadband applicant can satisfy the 90% Broadband Segment Test by purchasing or canceling channels from Covered Incumbents for cash or other consideration, by paying to relocate Covered Incumbents to replacement spectrum channels outside the broadband segment, or by demonstrating that the broadband applicant’s facilities will be far enough from the Covered Incumbent’s narrowband system to allow the two types of networks to co-exist.

Before filing for a broadband license, the broadband applicant must satisfy the 90% Broadband Segment Test by utilizing its channel holdings and negotiating with Covered Incumbents on a purely voluntary basis for any additional channels it requires to satisfy this test. Only after the 50% Licensed Spectrum Test and the 90% Broadband Segment Test are both satisfied will the FCC issue to the broadband applicant a broadband license. We can request a Mandatory Retuning of any Covered Incumbents that remain in the broadband segment (other than Complex Systems) which are required to negotiate in good faith with the broadband applicant to sell their channels or otherwise clear the 900 MHz Broadband Segment, subject to intervention by the FCC if the parties cannot reach an agreement.

MAP 3 below illustrates our licensed holdings (including those pending applications with the FCC) and the licensed holdings we have under contract by county in the 6 MHz broadband segment created by the Report and Order. This map does not reflect licenses that may meet the protection criteria as that is evaluated on a county basis as each broadband transition plan is prepared.

3.240 Channel Requirement. The Report and Order requires the broadband applicant to surrender 6 MHz of narrowband spectrum (or 240 channels) in the applicable county to the FCC in exchange for a broadband license. If the broadband applicant does not have sufficient channels in the county to return 240 channels to the FCC, it can elect to make an Anti-Windfall Payment to the U.S. Treasury to purchase spectrum. The Anti-Windfall Payment for these channels will be based on prices paid in the applicable county in the 600 MHz auction conducted by the FCC. To satisfy the 240 Channel Requirement, the broadband applicant has the option on a county-by-county basis to determine whether it is more cost-effective to make the Anti-Windfall Payment, purchase channels from incumbents (where available), or possibly a combination of both.

Importantly, the markets where we may need to make Anti-Windfall Payments to effectively have 240 channels are generally in smaller urban, suburban and rural markets. Our spectrum position is greatest in the largest, most populated and therefore most expensive markets, with a few exceptions as shown in MAP 4 below. Although we will need to make Anti-Windfall Payments to secure broadband licenses in some counties, the average cost in aggregate for the channels will be lower than the nationwide average amount of $0.93 per MHz of population covered paid in the FCC’s 600 MHz auction.

Costs of Securing Broadband Licenses

As discussed above, to obtain a broadband license in a county, the broadband applicant must satisfy (i) the 50% Licensed Spectrum Test, (ii) the 90% Broadband Segment Test and (iii) the 240 Channel Requirement. As the broadband applicant, we can satisfy these channel requirements by including our existing licensed channels in the 900 MHz band and by acquiring or clearing additional channels, when necessary, through (i) spectrum purchases, (ii) spectrum retuning and/or (iii) by making Anti-Windfall Payments. Under the Report and Order, we have the option of using each of these options alone, or in any combination required, to satisfy the broadband license eligibility requirements for a particular county.

1.Spectrum Purchase. In 2015, we began acquiring targeted additional channels in the 900 MHz band in various markets in anticipation of the Report and Order. We have and will continue to employ spectrum acquisition as a tool for those situations where an incumbent desires to exit the 900 MHz band. We also acquire channels outside the 900 MHz Broadband Segment and may use them to swap for channels within the broadband segment or to reduce the anti-windfall payments for licenses. For purposes of our broadband license eligibility, any contracted acquisitions negotiated in the 900 MHz

Page 14

Table of Contents

band may be included as part of our broadband application, but the acquisition does not need to be consummated at the time we submit our broadband license application for the purposes of calculating the 90% threshold.

2.Spectrum Retuning. Retuning is the exercise of modifying incumbents’ licenses to remove the broadband segment channels held by incumbents and swapping narrowband segments channels to facilitate a move to channels outside of the 900 MHz Broadband Segment established by the Report and Order. An agreement to retune adds to the number of channels we hold for computational purposes of the 90% Broadband Segment Test. We began retuning channels with interested incumbents in 2015 in anticipation of the Report and Order. We have continued retuning channels with incumbents since that time. For purposes of broadband license eligibility, any potential spectrum retuning agreements we negotiate in the 900 MHz band will be included as part of our broadband application, but the retune is not required to be completed before we submit our broadband license application.

3.Anti-Windfall Payment. To obtain a 6 MHz broadband license, we must surrender 240 licensed channels in the county. As this band has been underutilized historically, most counties in the United States do not have 240 outstanding licensed channels that can be surrendered. To make up for the difference, we effectively pay for channels from the FCC’s spectrum inventory by making an Anti-Windfall Payment. As noted above, the FCC will use a reference per channel price based on the average price paid in the FCC’s 600 MHz auction in each given county.

Our Intellectual Property

We rely on a combination of patent, copyright, trademark and trade-secret laws, as well as confidentiality provisions in our contracts, to protect our intellectual property. We have several trademarks and service marks to protect our current and future corporate name, services offerings, goodwill and brand. There are currently no claims or litigation regarding these trademarks, patents, copyrights, or service marks. We also rely on trade secret protection of our intellectual property. We enter into confidentiality agreements with third parties, employees and consultants when appropriate.

Regulation of Our Business

We hold FCC spectrum licenses in the 900 MHz band throughout the contiguous United States, plus Hawaii, Alaska and Puerto Rico. The FCC regulates our wireless spectrum holdings, the issuance of broadband licenses in the 900 MHz band in accordance with the Report and Order, our future leasing or sale of any broadband licenses we secure, and the future construction and operation of wireless networks, technologies and solutions utilizing our spectrum assets.

Licensing

We are authorized to provide our wireless communication services on specified frequencies within specified geographic areas and in doing so must comply with the rules, regulations and policies adopted by the FCC. The FCC issues each spectrum license for a fixed period, typically ten years in the case of the FCC narrowband licenses we currently hold and 15 years for any broadband licenses in accordance with the Report and Order. Any broadband licenses we secure will also have performance requirements at the 6- and 12-year marks to demonstrate that the broadband spectrum is being used to serve the public interest. While the FCC has generally renewed licenses held by operating companies like us, the FCC has the authority to both revoke a license for cause and to deny a license renewal if it determines that license renewal is not in the public interest. Furthermore, we could be subject to fines, forfeitures and other penalties for failure to comply with FCC regulations, even if any such non-compliance is unintentional. The loss of any licenses, or any related fines or forfeitures, could adversely affect our business, results of operations or financial condition.

The Communications Act of 1934, as amended, and FCC rules and regulations require us to obtain the FCC’s prior approval before assigning or transferring control of wireless licenses, with limited exceptions. The FCC’s rules and regulations also govern spectrum lease arrangements for a range of wireless radio service licenses, including the licenses we hold. These same requirements apply to any licenses or leases we may wish to enter into, transfer, or acquire as part of our broadband initiatives. The FCC may prohibit or impose conditions on any proposed acquisitions, sales, or other transfers of control of licenses or leases. The FCC engages in a case-by-case review of transactions that involve the consolidation or sale of spectrum licenses or leases and may apply a spectrum “screen” in examining such transactions. Because an FCC license is necessary to lawfully provide the wireless services we plan to enable, if the FCC were to disapprove of any such request to acquire, assign, or otherwise transfer a license or lease, our business plans would be adversely affected. Approval from the Federal Trade Commission and the Department of Justice, as well as state or local regulatory authorities, also may be required if we sell or acquire spectrum.

FCC Regulations

The FCC does not currently regulate rates for services offered by wireless providers. However, we may be subject to other FCC regulations that impose obligations on wireless providers, such as Federal Universal Service Fund obligations, which require communications providers to contribute to a fund that supports subsidized communications services to underserved areas and users; rules governing billing, subscriber privacy and customer proprietary network information; roaming obligations;

Page 15

Table of Contents

rules that require wireless service providers to configure their networks to facilitate electronic surveillance by law enforcement officials; rules governing spam, telemarketing and truth-in-billing and rules requiring us to offer equipment and services that are accessible to and usable by persons with disabilities, among others. There are also pending proceedings that may affect spectrum aggregation limits and/or adjustment of the FCC’s case-by-case spectrum screens; regulation surrounding the deployment of advanced wireless broadband infrastructure; the imposition of text-to-911 capabilities; and the transition to IP networks, among others. Some of these requirements and pending proceedings (of which the previous examples are not an exhaustive list) pose technical and operational challenges for which we, and the industry as a whole, have not yet developed clear solutions. We are unable to predict how these pending or future FCC proceedings may affect our business, financial condition, or results of operations. Our failure to comply with any applicable FCC regulations could subject us to significant fines or forfeitures.

State and Local Regulation

In addition to FCC regulations, we are subject to certain state regulatory requirements. The Communications Act of 1934, as amended, preempts state and local regulation of the entry of, or the rates charged by, any wireless provider. State and local governments, however, are permitted to manage public rights of way and can require fair and reasonable compensation from wireless providers for use of those rights of way so long as the compensation required is publicly disclosed by the government. The siting of base stations also remains subject to some degree of control by state and local jurisdiction.

Tower Siting

Our current and future customers who deploy broadband networks will be required to comply with various federal, state and local regulations that govern the siting, lighting and construction of transmitter towers and antennas, including requirements imposed by the FCC and the Federal Aviation Administration (“FAA”). Federal rules subject certain tower site locations to extensive zoning, environmental and historic preservation requirements and mandate consultation with various parties, including State and Tribal Historic Preservation Offices, which can make it more difficult and expensive to deploy facilities. The FCC antenna structure registration process also imposes public notice requirements when plans are made for construction of, or modification to, antenna structures that require FAA approval, potentially adding to the delays and burdens associated with tower siting, including potential challenges from special interest groups. To the extent governmental agencies continue to impose additional requirements like this on the tower siting process, the time and cost to construct towers could be negatively impacted. The FCC has, however, imposed a tower siting “shot clock” that requires local authorities to address tower applications within a specific timeframe, which can assist carriers in more rapid deployment of towers. More recently, the FCC also has adopted rules intended to accelerate broadband deployment by removing barriers to infrastructure investment, in particular for “small cell” equipment. Those rules have been challenged by certain municipalities and tribal nations both at the FCC and in court.

National Security

With a range of weather-related and cyber security impacts on the nation’s grid over the last several years, national security and disaster recovery issues continue to receive attention at the federal, state and local levels. For example, Congress is expected to again consider cyber security legislation to increase the security and resiliency of the nation’s digital infrastructure. Our current and future customers who deploy broadband networks may be required to comply with potential federal, state and local regulations that govern elements of the electric grid.

Report and Order

The FCC regulates the issuance of broadband licenses in the 900 MHz band in accordance with the Report and Order.
