PART I.

Item 1. Business 

Overview

Anterix Inc (“Anterix,” “we,” “our,” or the “Company”) is the utility industry’s partner, empowering enhanced visibility, control and security for a modern grid. Our vision is to deliver secure, scalable solutions enabled by private wireless broadband connectivity, for the benefit of utilities and the communities that they serve. As the largest holder of licensed spectrum in the 900 MHz band (896-901/935-940 MHz) throughout the contiguous United States, plus Hawaii, Alaska and Puerto Rico, we are uniquely positioned to deliver solutions that support secure, resilient and customer-controlled operations. We are focused on commercializing our spectrum assets and expanding the benefits and solutions we offer to enable our targeted utility and critical infrastructure customers to deploy private broadband networks.

Fiscal 2024 Highlights and Accomplishments

•Yielded positive cash flows primarily due to $106.5 million received in contracted cash proceeds from our customers

•Entered into a $30.0 million spectrum sale agreement with Lower Colorado River Authority (“LCRA”)

•Entered into a $34.5 million spectrum lease agreement with Tampa Electric Company (“TECO”)

•Transferred the San Diego County and Imperial County broadband licenses to San Diego Gas & Electric Company and recorded a $7.4 million gain on sale of intangible assets

•Exchanged narrowband for broadband licenses in 28 counties and recorded a $35.0 million gain

•Repurchased 735,646 shares of our stock to return capital to our stockholders for a total of $24.7 million

•Successfully led and completed initiatives in 3GPP to secure enhancements to the US 900 MHz Broadband Spectrum to benefit our customers, including the designation of a new Band 106 and n106, both for long-term evolution (“LTE”) and 5G

•Initiated a petition with the FCC aimed at expanding the current paired 3 x 3 MHz broadband segment to a paired 5 x 5 MHz broadband segment within the 900 MHz band

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 Anterix 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 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 52% of the 900 MHz band in the United States. However, where spectrum is the highest priced, 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 Specialized Mobile Radio (“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, therefore no users acquired site-based licenses utilizing this spectrum. As a result, the FCC is currently holding over 24% of 900 MHz narrowband spectrum in its inventory in most counties throughout the United States.

Broadband licenses

As of March 31, 2024, we were cumulatively granted by the FCC broadband licenses for 133 counties. As a result, we relinquished to the FCC our narrowband licenses and made the necessary Anti-Windfall Payments for the same 133 counties, as required by the Report and Order. During fiscal year 2024, we transferred 2 FCC broadband licenses to our customer pursuant to the terms of our spectrum sale agreement. As of March 31, 2024, we held 131 FCC broadband licenses.

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) which we have customer contracts, (ii) where we believe we have near-term commercial prospects, or (iii) 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 Certification 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 three 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 Anterix has 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 Program (“AAEP”); and

•launching our Utility Strategic Advisory (“USAB”).

UBBA membership currently includes 34 electric utilities among its nearly 106 members. The AAEP includes participation of over 100 leading technology companies that provide deployment and application solutions for private broadband targeting our Nation’s electric grid innovators. We launched the AAEP to foster, strengthen, and expand the landscape of 900 MHz devices, services and solutions. Participation from the broad range of technology innovators will bring extensive value to utilities and other critical infrastructure providers who deploy PLTE.

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 Certification 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 AAEP; 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.

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 five experimental licenses granted to non customer utilities and six experimental licenses 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 leasing of 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 has recently 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, as well as a transition to 5G, which received worldwide wireless industry support. 3GPP is approved and will incorporate Band 106 and n106, 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 Success

We have invested in building our business development, sales, marketing and other supporting 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 arrangements, 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.

be recognized over time as the performance obligations of clearing the 900 MHz Broadband Spectrum and the associated broadband leases are delivered by respective county, over the contractual term of approximately 20 years.

TECO Agreement

In November 2023, we entered into an agreement with TECO to provide TECO the use of our 900 MHz Broadband Spectrum for a term of 20 years throughout TECO’s service territory in West Central Florida (the “TECO Agreement”). The TECO Agreement also provides TECO an option to extend the agreement for two 10-year terms for additional payments. The TECO Agreement, which covers an approximately 2,000-square-mile service territory in West Central Florida, is expected to enable TECO to deploy a PLTE network. The scheduled prepayments for the 20-year initial term of the TECO Agreement total $34.5 million, of which $6.9 million was received in December 2023. The remaining prepayments for the 20-year initial term are due by fiscal year 2026, per the terms of the TECO Agreement and as we deliver the relevant cleared 900 MHz Broadband Spectrum and the associated broadband leases. The TECO Agreement is subject to customary provisions regarding remedies for non-delivery, including refund of amounts paid and termination rights if we fail to perform our contractual obligations, including failure to deliver the relevant cleared 900 MHz Broadband Spectrum in accordance with the terms of the TECO Agreement. We are working with incumbents to clear the 900 MHz Broadband Spectrum allocation in TECO service territories. In accordance with ASC 606 Revenue from Contracts with Customers, the payments of prepaid fees under the TECO Agreement will be accounted for as deferred revenue on our Consolidated Balance Sheets.

Sales of 900 MHz Broadband Spectrum

SDG&E Agreement

In February 2021, we entered into an agreement with SDG&E to sell 900 MHz Broadband Spectrum throughout SDG&E’s California service territory, including San Diego and Imperial Counties and portions of Orange County (the “SDG&E Agreement”) for a total payment of $50.0 million. The SDG&E Agreement will support SDG&E’s deployment of a PLTE network for its California service territory, with a population of approximately 3.6 million people. As part of the SDG&E Agreement, SDG&E and Anterix are collaborating to accelerate the utility industry momentum for private networks. The

Page 10

SDG&E Agreement includes the assignment of 6 MHz of 900 MHz Broadband Spectrum, 936.5 – 939.5 MHz paired with 897.5 – 900.5 MHz, within SDG&E’s service territory following the FCC’s issuance of the broadband licenses to us. The total payment of $50.0 million is comprised of an initial payment of $20.0 million, received in February 2021 and the remaining payments which are due as we deliver the relevant cleared 900 MHz Broadband Spectrum and the associated broadband licenses to SDG&E. The SDG&E Agreement is subject to customary provisions regarding remedies for non-delivery, including refund of amounts paid and termination rights if Anterix fails to perform its contractual obligations, including failure to deliver the relevant cleared 900 MHz Broadband Spectrum in accordance with the terms of the SDG&E Agreement. A gain or loss on the sale of spectrum will be recognized for each county once we deliver the cleared 900 MHz Broadband Spectrum and the associated broadband licenses to SDG&E in full.

In September 2022, we transferred to SDG&E 1.4 x 1.4 MHz cleared 900 MHz Broadband Spectrum and the associated broadband license related to Imperial County and received a milestone payment of $0.2 million. In September 2023, we transferred to SDG&E the San Diego County broadband license and received a milestone payment net of delivery delay adjustments of $25.2 million. In December 2023, we transferred to SDG&E the remainder of the cleared 900 MHz Broadband Spectrum and the associated broadband license related to Imperial County and received a milestone payment of $0.2 million. This resulted in the recognition of a gain on the sale of spectrum and derecognition of the contingent liability associated with San Diego County and Imperial County.

LCRA Agreement

In April 2023, we entered into an agreement with LCRA to sell 900 MHz Broadband Spectrum covering 68 counties and more than 30 cities in LCRA’s wholesale electric, transmission, and water service area (the “LCRA Agreement”) for total payments of $30.0 million plus the contribution of select LCRA 900 MHz narrowband spectrum. The LCRA Agreement will support LCRA’s deployment of a PLTE network which will provide a host of capabilities including grid awareness, communications and operational intelligence that will enhance resilience and spur innovation at LCRA. The new licenses will enable LCRA to move from narrowband to next generation broadband and provide mission-critical data and voice services within LCRA and to more than 100 external customers such as electric cooperatives, schools and transit authorities across more than 73,000 square miles. The payment of $30.0 million is due through fiscal year 2026 as we deliver the relevant cleared 900 MHz Broadband Spectrum and the associated broadband licenses to LCRA. During the year ended March 31, 2024, we received an initial $15.0 million payment, of which $7.5 million was deposited in an escrow account. The LCRA Agreement is subject to customary provisions regarding remedies for non-delivery, including refund of amounts paid and termination rights if Anterix fails to perform its contractual obligations, including failure to deliver the relevant cleared 900 MHz Broadband Spectrum in accordance with the terms of the LCRA Agreement. A gain or loss on the sale of spectrum will be recognized for each county once we deliver the cleared 900 MHz Broadband Spectrum and the associated broadband licenses to LCRA in full.

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 this lease agreement with Motorola, 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 lease agreement limits the total number of channels that Motorola can lease in any market area. The lease agreement 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.

Competition

Our competitors include retail wireless network providers, such as Verizon, AT&T, T-Mobile, and EchoStar, private radio operators and other public and private companies who supply spectrum or other communication networks, technologies, products and solutions to our targeted utility and critical infrastructure enterprises. 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

Page 11

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 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.

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.”

Page 12

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 eight 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 and return them to the FCC in accordance with the AAR Agreement. We cancelled these licenses in June 2020. The Report and Order provided the FCC to modify their license to provide the additional channels to AAR to enable the railroads to relocate their current operations. This modification to remove broadband segment channels is 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

Page 13

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 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” (i.e., holders of licenses in the broadband segment) 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 and therefore commence the mandatory retuning period. 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 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 and commence the “Mandatory Retuning” period. During this Mandatory Retuning period, any Covered Incumbents that remain in the broadband segment (other than Complex Systems) 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 and 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.

Page 14

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 effectively purchase unlicensed channels in the FCC’s inventory. 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 the FCC has channels in inventory and where we may need to make Anti-Windfall Payments to effectively return 240 channels to the FCC 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 (“POP”) paid in the FCC’s 600 MHz auction.

Page 15

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 a Covered Incumbent desires to exit the 900 MHz band. We may selectively acquire channels outside the 900 MHz Broadband Segment and use them to swap for channels within the broadband segment. For purposes of our broadband license eligibility, any potential acquisitions we negotiate in the 900 MHz 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.

2.Spectrum Retuning. Retuning is the exercise of modifying incumbents’ licenses to remove the broadband segment channels held by Covered 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 Covered Incumbents in 2015 in anticipation of the Report and Order. We have continued retuning channels with Covered 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 the difference, we may 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 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; 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

Page 17

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 regulation, 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.

Risks Related to Obtaining Broadband Licenses, the Retuning Process and the Use of Our Spectrum

Our plans to commercialize our 900 MHz spectrum assets depend on our ability to qualify for and obtain broadband licenses from the FCC in accordance with the requirements of the Report and Order. If we are unable to obtain broadband licenses on favorable terms and on a timely basis, our business, liquidity, results of operations and prospects will be materially adversely affected.

Our plans to commercialize our 900 MHz spectrum assets depend on our ability to obtain broadband licenses in accordance with the requirements of the Report and Order. The Report and Order establishes three general eligibility requirements to obtain a broadband license, which we refer to herein as (i) the “50% Licensed Spectrum Test,” (ii) the “90% Broadband Segment Test” and (iii) the “240 Channel Requirement.” We will need to satisfy all eligibility requirements in each county in the United States for which we desire to obtain a broadband license. Under the 50% Licensed Spectrum Test, we must demonstrate that we hold more than 50% of the licensed channels in the 900 MHz band in the applicable county. Under the 90% Broadband Segment Test, we must provide the FCC with a plan demonstrating that we hold, or have agreements with Covered Incumbents for, at least 90% of the licensed channels in the 6 MHz broadband segment designated by the FCC and within 70 miles of the county boundary. Under the 240 Channel Requirement, we must surrender 6 MHz of broadband or narrowband spectrum (or 240 channels) in the applicable county to the FCC. If we do not have a sufficient number of channels to satisfy any of these eligibility requirements, we will be required to purchase the additional channels from incumbents in privately negotiated transactions, swap our existing channels with incumbents (including any required retuning of the incumbent radio systems), demonstrate the ability to protect Covered Incumbents or effectively purchase channels not previously licensed by the FCC by making an Anti-Windfall Payment. The amount of spectrum we will be required to purchase and/or swap and the amount of any Anti-Windfall Payment will vary in each county based on our existing spectrum holdings in such county. Our ability to acquire and/or swap the additional spectrum necessary to secure broadband licenses in a desired county on a timely and cost-effective basis will depend on the incumbents who hold the additional spectrum we need to acquire or swap and their operations that we may need to retune or replace. Obtaining the required spectrum to qualify for broadband licenses may take longer and be more expensive than we currently anticipate. In addition, as discussed in more detail below, incumbents may elect not to sell or swap their existing channels on reasonable terms, or at all, and until we obtain a broadband license from the FCC, we will not be able to utilize the Mandatory Retuning procedures the FCC established in the Report and Order. If we are unable to obtain broadband licenses on favorable terms and on a timely basis, or at all, our business, liquidity, results of operations and prospects will be materially adversely affected. In addition, significant costs or delays beyond what we have anticipated in our business plan will further delay us from commercializing our spectrum assets, may prevent us from returning capital to stockholders (through dividends or stock repurchases), and require us to seek additional sources of capital and liquidity in order to carry out our business and plans, which could cause significant dilution to our existing stockholders. See the risk factor entitled “We may not be able to correctly estimate our operating expenses or future revenues, which could lead to cash shortfalls, and may prevent us from returning capital to our stockholders and require us to secure additional financing.”

The voluntary exchange process established by the FCC in the Report and Order may not allow us to clear or relocate incumbents in a timely manner and on commercially reasonable terms, or at all.

The Report and Order establishes a market-driven, voluntary exchange process for clearing the channels in the broadband segment. When we apply for a broadband license, we will need to demonstrate that we satisfy the 90% Broadband Segment Test. The fact that we will need to account for 90% of the licensed channels in the broadband segment before we can file for a broadband application, can lead to holdouts by Covered Incumbents. For example, a Covered Incumbent may demand compensation in an amount that is disproportionate to the cost of relocating its system or any reasonable reflection of the value of its spectrum holdings or may elect not to negotiate an agreement at all. There is no assurance, however, that we can swap or acquire sufficient channels, including purchasing additional spectrum, swapping spectrum or entering into protective agreements with Covered Incumbents, to satisfy the 90% Broadband Segment Test on a timely basis and on commercially reasonable terms, or at all. Further, even if we satisfy the 90% Broadband Segment Test, as part of the Mandatory Retuning process we will be required to pay any costs associated with providing Covered Incumbents with comparable facilities and paying relocation costs. In the Report and Order, the FCC has established that a Broadband license can trigger a Mandatory Retuning process to help a broadband applicant clear the remaining channels in the broadband segment.

Page 20

In addition, the FCC has exempted channels from the Mandatory Retuning process that are being utilized by incumbents operating Complex Systems. The FCC exempted Complex Systems from the Mandatory Retuning requirements because retuning these systems could be complex and disruptive to the incumbent operators. Complex Systems are located in some of the largest business and population centers in the United States. Most are operated by electric utilities, including some utilities that actively opposed our 900 MHz Broadband Spectrum initiatives that resulted in the Report and Order. This exemption effectively prevents us from obtaining broadband licenses in counties where these Complex Systems are located (or if a Complex System is being operated within 70 miles of a county boundary for which we are attempting to obtain a broadband license) without the incumbent’s consent, which could be withheld for any reason, or for no reason. As a result, the incumbents operating Complex Systems can make demands that are not commercially reasonable (including the commercial terms to obtain the use of our spectrum), delay their decision or refuse to negotiate with us altogether. Our inability to obtain broadband licenses in counties where Complex Systems are currently being operated (or are being operated within 70 miles of a county boundary for which we are attempting to obtain a broadband license) could have a material adverse effect on our operations and business plan, our future prospects and opportunities and on our ability to develop a profitable business.

The members of the AAR may delay or hinder our ability to commercialize broadband licenses.

The AAR holds a nationwide geographic license for six non-contiguous channels in the 900 MHz band, three of which are located within the broadband segment established by the FCC in the Report and Order. These channels are used by freight railroads for Advanced Train Control System operations. We recognized from the outset of the 900 MHz proceedings the importance of reaching agreements with the railroads about their relocation and worked with them throughout the FCC process. The Report and Order acknowledged the agreement we had reached with the AAR. In January 2020, we formalized our AAR Agreement with the AAR in which we agreed to provide 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. We cancelled these licenses in June 2020 in accordance with the AAR Agreement and the FCC Report and Order. Delays by members of the AAR in clearing their channels in the broadband segment could delay or hinder our ability to commercialize broadband licenses and the ability of our customers to deploy 3 x 3 MHz broadband networks in the affected area, which could cause delays, penalties or have a material adverse effect on our operations and business plan, our future prospects and opportunities and on our ability to develop a profitable business.

We may not be successful in commercializing our spectrum assets to our targeted utility and critical infrastructure customers, on a timely basis, including those customers that are above the Demonstrated Intent threshold, or in accordance with our business plans and expectations.

We have identified utilities and other critical infrastructure enterprises as our initial target customers. As of the date of this filing, we have signed long-term leases of our spectrum assets with Ameren, Evergy, Xcel Energy, and TECO and have entered into agreements to sell our spectrum assets to SDG&E and LCRA. Although we are in discussions with other utilities and critical infrastructure enterprises, there is no assurance that these discussions will continue to progress or eventually result in contracts with these entities or that we will be successful in our efforts to commercialize our spectrum assets and other service offerings. For example, utilities or other critical infrastructure enterprises may not elect to acquire use of any broadband licenses we secure on terms satisfactory to us or for a consideration that represents what we believe is the fair market value for the rights to our spectrum, on a timely basis, or at all. Similarly, there is no assurance that utilities or other critical infrastructure customers will retain us for any other value-added services we offer them. As a result, our prospects must be considered in light of the uncertainties, risks, expenses and difficulties frequently encountered by companies in their early stages of implementing a new business plan and pursuing opportunities in highly competitive and rapidly developing markets.

In addition, under our current business plan, we generally intend to enter into long-term leasing or other transfer arrangements for our spectrum assets in one county with one customer, or a limited number of customers, in each geographic area. We also expect that our customers will pay what we believe is the fair market value for rights to our spectrum and bear the costs of deploying and operating their private wireless broadband networks. As a result, many geographic areas may have only one or a limited number of potential customers and if we are not successful with the initially targeted customer or limited number of customers, our spectrum may not be utilized, and we will not be able to generate revenues from owning spectrum in that geographic area. In addition, even if we enter a long-term lease or transfer arrangement for a geographic area, we expect payments by our customer in such area will be contingent on our ability to clear incumbents and take the other necessary actions to secure broadband licenses on a timely basis. Our customers also will typically require rights to all spectrum we have in its geographic operating area. Because of this, we may not have additional spectrum assets to lease in such geographical area to other potential customers. Further, other than our lease or transfer arrangements, currently we do not generate revenue from the operation of the broadband networks or technologies deployed by our customers. As a result, there is considerable uncertainty as to whether we can generate sufficient revenues to develop a profitable business from leasing or otherwise transferring our licensed 900 MHz spectrum on a timely basis, or at all.

Our ability to successfully commercialize our spectrum assets will also depend on the commercial availability of technology, products and solutions that can both utilize the broadband licenses we secure and satisfy our customers’ demands.

Page 21

Our spectrum assets are located within the 3GPP global standard of Band 8 (also known as the E-GSM band, or 880 - 915 MHz paired with 925 - 960 MHz). Band 8 is currently being utilized in LTE and 5G networks, with a specific designation for the US under band 106 / n106. However, chipmakers and other technology, product and solution manufacturers and vendors may not continue to develop the technology, products and solutions required to satisfy our customers’ various use cases and meet the technical specifications established in the Report and Order. Further, adverse economic conditions, including as a result of health pandemics, inflation, regulatory actions and policy changes, and geopolitical matters, may result in supply chain issues which limit our customer’s ability to obtain the necessary technology and products to deploy an LTE or 5G wireless broadband network utilizing our spectrum. If such technologies, products and solutions are not available, not competitively priced or are significantly delayed, our targeted customers may decide not to pursue 900 MHz broadband licenses with us on acceptable terms, on a timely basis, or at all.

Our assessment that we should target utilities and other critical infrastructure entities as potential customers for our spectrum is based on our determination that these entities will need to install a significant number of new technologies, such as smart devices and sensors, that will generate an increasing amount of data that cannot be addressed well by their existing communication networks and systems. Our potential customers, however, are large organizations and their decision to implement private broadband networks, technologies and solutions is an involved decision and will require significant capital outlays. Any negotiation and contract process with these potential customers has taken, and likely will continue to take, a significant amount of time and effort to work through their approval and funding processes. In addition, there is no assurance that the governmental agencies that regulate these entities will allow them to pass the capital costs of implementing broadband networks, technologies and solutions utilizing our spectrum on to their ratepayers, which could cause these entities to be unable to afford, or to elect not to pursue, rights to our spectrum assets. In addition, although there is broad availability of broadband LTE, there is no assurance that our targeted customers will be able to utilize existing networks, technologies and solutions with our spectrum for their desired use cases without requiring modifications to existing equipment or engaging in product and/or service development efforts, any of which could result in deployment delays, require them or us to invest in technology or other development activities or otherwise adversely limit the potential benefits or value of our spectrum assets. If any of these risks occur or continue beyond our plans and expectations, our plans to commercialize our spectrum assets may not be as valuable as we expect and we may experience significant delays in our commercialization plans, which will have an adverse effect on our business, liquidity, results of operations and prospects.

We may not be successful in developing, marketing, selling and delivering new products and services to our targeted utility and critical infrastructure customers.

In addition to the leasing and sale of our spectrum assets, we are seeking to expand our product and service offerings to leverage and enhance the value of our spectrum assets. Most notably, we are actively marketing CatalyX, a turnkey connectivity management solution that helps utilities realize the benefits of private broadband networks, while leveraging commercial broadband networks. We also continue to explore other service offerings to help our customers deploy systems using our service offerings. We face significant competition in development, sale, and delivery of products and services related to our spectrum to our customers. Many of these competitors have significantly larger workforces, a broad array of capabilities, deep customer relationships, and greater financial resources. We may not be able to adequately compete in sales of these additional offerings, or be unable to develop, market or deliver competitive offerings.

We are subject to contingencies and obligations under our commercial agreements with our customers including the delivery of cleared spectrum and broadband licenses on a timely basis, and as a result, there is no assurance that we will receive payments from such customers in the amounts and on the timeline we currently expect, or that any payments we have received to date from our customers, will not be subject to repayment or that we will not be subject to contract claims, including rights of termination.

We are subject to contingencies and obligations under our commercial agreements with our customers, including the delivery of cleared spectrum and broadband licenses in the designated service territories on a timely basis. There is no assurance that we will be able to clear incumbents from our customers’ respective service territories and obtain broadband licenses from the FCC on the timeline required under our agreements, or at all. Customers’ respective payment obligations, including our ability to maintain any upfront payments and any future payment obligations under these agreements, are contingent on our ability to deliver cleared spectrum and Broadband Spectrum licenses on the timelines required in these agreements. As a result, there is no assurance that we will be able to retain any upfront payments or receive future payments in the amounts and on the timeline we currently expect, or at all. Additionally, our customers may not elect to exercise their options for additional terms contemplated by the terms of the long-term lease agreements. Further, our costs to clear incumbents, qualify for broadband licenses and perform our other obligations under our agreements with our customers may be significantly more than we currently anticipate, which could increase our capital expenses and reduce our net income or increase our net loss.

Page 22

Macroeconomic pressures resulting from health epidemics, unfavorable market conditions, regulatory and policy changes, and ongoing geopolitical matters, may have an adverse impact on our business, financial results, stock price and results of operations as well as the business of our current and potential customers.

Recent macroeconomic events, inflation, and geopolitical matters, have created significant negative macroeconomic conditions, such as decreases in per capita income and level of disposable income, inflation, rising interest rates, and supply chain issues, resulting in significant economic uncertainty as well as volatility in the financial markets and new regulatory and policy initiatives particularly in the United States. Such conditions may adversely impact our business, financial results and prospects and our target customers’ businesses. In addition, such macroeconomic conditions could impact our ability to access the public markets as and when appropriate or necessary to carry out our operations or our strategic goals. We cannot predict the ongoing extent, duration or severity of these conditions, nor the extent to which we may be impacted.

Worsening macroeconomic conditions could negatively impact or disrupt our business, operations and results of operations. Such impacts or disruptions may be similar to those we faced during the COVID-19 pandemic, which included mandated business closures in impacted areas, limitations with employee resources due to stay at home orders or sickness of employees or their families, reduction of our business operations and the business operations of our targeted utility and critical infrastructure customers, all of which may have an adverse impact on our business, financial results, stock price and results of operations.

Our customers’ initiatives with the federal and state agencies and commissions that regulate electric utilities may not be successful, which may impact our commercialization efforts.

Our targeted utility and critical infrastructure customers are highly regulated by both federal and state agencies. Electrical utilities, for example, are regulated by federal agencies including the Department of Energy, the Department of Homeland Security, the Federal Energy Regulatory Commission and the NIST. We are working with each of these agencies to educate them about the potential benefits that private broadband LTE networks, technologies and solutions utilizing our spectrum assets can offer utilities. We are also working with state agencies and commissions who regulate the electrical utilities in their respective states, and who have a strong influence over electric utility buying decisions in their jurisdictions. Our goal with these state agencies and commissions is to gain their support for allowing utilities to pass the capital costs of leasing or purchasing our spectrum assets and deploying private broadband LTE networks, technologies and solutions to ratepayers, including at a customary rate of return for the utility company. We are in the early stages of our initiatives with these federal and state agencies and commissions. We may not be successful in gaining support from these governmental bodies on a timely basis, or at all, which could hinder or delay our commercialization efforts with utilities and other entities. If we do not gain support from these governmental bodies, our targeted critical infrastructure customers may not find it commercially feasible to lease our spectrum assets.

We may not be able to maintain any broadband licenses that we own and/or obtain from the FCC.

The FCC issues each spectrum license for a fixed period, typically ten years in the case of the FCC licenses for the narrowband spectrum we currently hold and 15 years for any broadband licenses we have or intend to secure in the future. The Report and Order establishes “performance” or build-out requirements that we will be required to meet to retain and renew any broadband licenses we obtain (“Build-out Requirements”). Performance will be measured at the six- and twelve-year anniversaries of each broadband license. Although we have contractual rights and remedies with our licensees in the event of their failure to meet the Build-Out Requirements, a failure to satisfy the six-year anniversary requirements, accelerates the twelve-year anniversary to a ten-year anniversary requirement. A failure to satisfy these requirements could result in the FCC’s termination of a broadband license or refusal to renew a previously issued broadband license. In addition, under our business plan, we intend for our customers to be responsible to pay the build-out and operating costs of such broadband systems. Such Build-Out Requirements could impose a significant expense and could cause potential customers to decide not to license broadband licenses from us, or to seek alternative communication solutions from other providers. Additionally, if the customer fails to satisfy these requirements, we have the step in rights to meet the Build-Out Requirements which could impose a significant expense on our business.

We may not be able to maintain any narrowband licenses that we own and/or obtain from the FCC or other licensees.

The FCC issues each spectrum license for a fixed period, typically ten years in the case of the FCC licenses for the narrowband spectrum we currently hold or intend to secure in the future. Our narrowband licenses are necessary for us to meet the eligibility requirements of becoming a broadband licensee and hence to obtain a broadband license. Narrowband licenses have met their construction requirements and upon the expiration date must be renewed. These renewals are subject to continued certification that they are constructed and operational. Although we have contractual rights with site owners and operators, a failure to maintain these operations could occur outside of our control. A failure to satisfy these requirements could result in the FCC’s termination of a narrowband license or refusal to renew a previously issued narrowband license.

Page 23

Government regulations or actions taken by governmental bodies could adversely affect our business prospects, liquidity and results of operations, including any changes by the FCC to the Report and Order or to the FCC rules and regulations governing the 900 MHz band.

The licensing and sale of spectrum assets, as well as the deployment and operation of wireless networks and technologies, are regulated by the FCC and, depending on the jurisdiction, by state and local regulatory agencies. In particular, the FCC imposes significant regulation on licensees of wireless spectrum with respect to how FCC licenses may be transferred or sold. The FCC also regulates how the spectrum is used by licensees, the nature of the services that licensees may offer and how the services may be offered, including resolution of issues of interference between spectrum bands. Failure to comply with FCC requirements applicable to a given licensee could result in revocation or non-renewal of the license, depending on the nature and severity of the non-compliance. If we, or any of the future licensees of our spectrum assets, fail to comply with applicable FCC regulations, we may be subject to sanctions or lose our FCC licenses, which would have a material adverse effect on our business, liquidity, results of operations and prospects.

In addition, the FCC and other federal, state and local governmental authorities could adopt new regulations or take actions, including imposing taxes or fees on our business that could have a materially adverse effect on our business, liquidity, results of operations and prospects. Further, the FCC or Congress may make additional spectrum available for communications services, which may result in the introduction of additional competitive entrants to the already crowded wireless communications marketplace in which we compete. For example, the federal government created and funded the FRNA which the federal government authorized to help accomplish, fund and oversee the deployment of the dedicated NPSBN. The NPSBN, which is marketed as “FirstNet”, may provide an additional source of competition to utilizing our 900 MHz spectrum assets by our targeted critical infrastructure and enterprise customers.

The value of our spectrum assets may fluctuate significantly based on supply and demand, as well as technical and regulatory changes.

The FCC spectrum licenses we hold are our most valuable asset. The value of our spectrum, however, may fluctuate based on various factors, including, among others:

•the cost and time required to comply with the FCC’s requirements to obtain broadband licenses in the 900 MHz band, including purchasing additional spectrum and retuning and relocating incumbents;

•our ability to enter long-term leases or transfer arrangements with our targeted utility and critical infrastructure customers on a timely basis and on commercially reasonable terms;

•potential uses of our spectrum based on the Report and Order and available technology;

•the market availability of, and demand for, broadband spectrum;

•the supply of broadband spectrum made available to our targeted customers by existing wireless carriers;

•the demand for private broadband networks, technologies and solutions by our targeted utility and critical infrastructure customers; and

•regulatory changes by the FCC to make additional spectrum available or to promote more flexible uses of existing spectrum in other bands.

Similarly, the price of any additional spectrum we desire to purchase to enable us to qualify for broadband licenses or our future business plans will also fluctuate based on similar factors. Any decline in the value of our spectrum or increases in the cost of the spectrum we acquire could have an adverse effect on our market value and our business and operating results.

We may not be successful in the petition filed with the FCC to expand the 900 MHz Broadband Segment from 6 MHz to 10 MHz.

On February 28, 2024, several interested parties, including major utilities, trade associations, and Anterix Inc., filed a Petition for Rulemaking 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. The FCC’s action may take a number of forms ranging from a Report and Order, a Notice of Proposed Rulemaking, a Notice of Inquiry, a dismissal of the Joint Petition without further action to no action. We believe in the merits of the proposal, and that our Joint Petition is consistent with the FCC’s practices and policies. Nevertheless, obtaining a favorable result from the FCC may take a significant amount of time and resources. Moreover, there is no assurance that the FCC will ultimately approve our Joint Petition or will conduct a rulemaking proceeding along the lines originally advocated by us. As a result, our ability to successfully expand the 900 MHz Broadband Segment from 6 MHz to 10 MHz, could require more attention from our senior management team and be more expensive than we currently anticipate, and we ultimately may not be able to obtain the necessary regulatory approvals.

Risks Related to Our Business

We may not be able to correctly estimate our operating expenses, future cash proceeds or future revenues, which could lead to cash shortfalls, and may prevent us from returning capital to our stockholders and require us to secure additional financing.

We dedicated significant resources to support the FCC’s approval of the Report and Order. We have expended, and will need to continue to expend substantial resources for the foreseeable future, to commercialize and promote the benefits of deploying broadband systems to our targeted utility and critical infrastructure customers. We also will need to expend substantial resources for the foreseeable future to qualify for and obtain broadband licenses, including the costs related to retuning incumbent systems, purchasing additional spectrum from incumbents and/or making Anti-Windfall Payments to the U.S. Treasury to commercialize our spectrum assets. We believe our cash and cash equivalents on hand, along with contracted proceeds from customers will be sufficient to meet our financial obligations through at least 12 months from the date of this filing.

Our budgeted expense levels are based in part on our expectations and assumptions regarding the timing and costs to qualify for and obtain broadband licenses, the demand by our target customers to utilize our spectrum assets to deploy broadband networks, technologies and solutions and the time required to enter into binding contracts with our target customers. However, we may not correctly predict the amount or timing of our future contract proceeds, revenues and our operating expenses, which may fluctuate significantly in the future as a result of a variety of factors, many of which are outside of our control, and may be materially different than our announced plans and expectations. These factors include:

•the cost and time required to obtain broadband licenses, including the costs to clear the 900 MHz band and to acquire additional spectrum from incumbents and/or to make Anti-Windfall Payments;

•our ability to qualify for and utilize the Mandatory Retuning process established by the Report and Order;

•our ability to negotiate agreements with the operators of Complex Systems;

•the cost and time to promote, market and commercialize our spectrum assets, including the long sales cycle required to enter commercial arrangements with our targeted utility and critical infrastructure customers;

•the commercial terms, including the length of the lease and the timing of payments, in our future commercial arrangements with our targeted customers;

•the costs associated with increasing the size of our organization, including the costs to attract and retain personnel with the skills required to support our business plans;

•adverse economic conditions, including as a result of inflation, that delay or otherwise hinder our commercialization efforts; and

•the funds we return to stockholders through our share repurchase program.

Other costs may arise that we currently do not anticipate and unanticipated events may occur that reduce the amounts and delay the timing of our future revenues. We may not be able to adjust our operations in a timely manner to compensate for any shortfall in our revenues, delays in obtaining broadband licenses, delays in entering commercial agreements for our spectrum or increases in the expenses required to secure broadband licenses and implement our commercialization and business plans.

Further, our assumptions regarding the terms of any spectrum transactions we enter into with our targeted customers, including the timing of customer payments, may turn out to be inaccurate. As a result, a significant shortfall in our planned revenues, a significant delay in obtaining broadband licenses, a delay in entering into agreements for our spectrum assets, future customers electing not to make significant pre-payments under the terms of any agreements we enter into or significant increases in our planned expenses could have an immediate and material adverse effect on our business, liquidity, results of operations and prospects. In such case, we may not be able to return capital to our stockholders through dividends or stock repurchases and may be required to issue additional equity or debt securities or enter into other commercial arrangements to secure the additional financial resources to support our future operations and the implementation of our business plans. Such financing may result in dilution to stockholders, imposition of debt covenants and repayment obligations, or other restrictions that may adversely affect our business, prospects and results of operations. In addition, we may seek additional capital due to market conditions or strategic considerations even if we believe we have sufficient funds for our current or future operating plans.

We have a limited operating history with our current business plan, which makes it difficult to evaluate our prospects and future financial results and our business activities, strategic approaches and plans may not be successful.

Although we were incorporated in 1997, our business is now reliant on our ability to secure broadband licenses pursuant to the Report and Order and to commercialize our spectrum assets to our targeted utility and critical infrastructure customers. Since the Report and Order, we have signed commercial agreements with five of our target utility and critical infrastructure customers for the long-term lease or transfer of our spectrum assets. Although we are in discussions with other utilities and critical infrastructure companies, and we believe many of these utility and critical infrastructure customers have

Page 25

demonstrated an intention to acquire use of our 900 MHz Broadband Spectrum based on their level of engagement, there is no assurance that these discussions will continue to progress or will eventually result in contracts with these entities. There also is no assurance regarding the terms of any agreements we enter into with our target customers, including the time required to enter into an agreement and the amount or timing of any payments from any executed agreement. In addition, there is no assurance that we will be able to satisfy our obligations under our commercial agreements, including our obligations to secure broadband licenses on a timely basis and on commercially reasonable terms, or at all. As a result, there is no assurance that we will be successful in our efforts to commercialize our spectrum assets and other service offerings. Further, our ability to forecast our future operating results is limited and subject to a number of risks and uncertainties, including our ability to accurately forecast and estimate our future revenues and the expenses and time required to obtain broadband licenses and pursue our commercialization plans. We have encountered, and expect to continue to encounter, risks and uncertainties frequently experienced by new businesses in highly competitive, technical and rapidly changing markets. If our assumptions regarding these risks and uncertainties are incorrect, or if there are adverse changes in our commercialization plans or opportunities or general economic conditions, or if we do not manage or address these risks and uncertainties successfully, our results of operations could differ materially and adversely from our expectations.

As a business with a limited operating history with our current business plan, any future success will depend, in large part, on our ability to, among other things:

•comply with the requirements and restrictions the FCC has established in the Report and Order to qualify for and obtain broadband licenses in key geographic areas on a timely and cost-effective basis;

•successfully commercialize our spectrum assets to our targeted utility and critical infrastructure customers on favorable terms, on a timely basis, or at all;

•comply with our obligations under our existing and any future agreements with our customers on a timely basis and on commercially reasonable terms;

•compete against other wireless companies, such as Verizon, AT&T, T-Mobile, and EchoStar, manufacturers and vendors who have significantly greater resources and pricing flexibility, long-term relationships with our targeted customers and greater political and regulatory influence;

•successfully convince chipmakers and other technology, product and solution manufacturers and vendors to develop the technology, products and solutions required to satisfy our customers’ various use cases and meet the technical specifications established in the Report and Order; and

•successfully manage and grow our internal business, regulatory, technical and commercial operations in an efficient and cost-effective manner.

Any failure to achieve one or more of these objectives could adversely affect our business, our results of operations and our financial condition.

Several of the third parties who offer spectrum and communication technologies, products, services and solutions to our targeted customers have existing long-term relationships with these targeted customers and have significantly more resources and greater political and regulatory influence than we do, and we may not be able to successfully compete with these third parties.

Our competitors include 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. Several of these competitors have significantly more resources, a longer track record of providing technologies, products, services and solutions to our targeted customers and greater political and regulatory influence than we do, all of which could prevent, delay or increase the costs of commercializing the broadband licenses we secure to our targeted customers. In addition, we expect our targeted customers will bear the cost of installing and operating the broadband networks, technologies and solutions utilizing our licensed spectrum, thereby requiring the replacement of some or all of their existing communication systems. Given these significant capital requirements, there is no assurance that we will be able to successfully commercialize our spectrum assets, especially in light of the competitive environment in which we operate, and the wide variety of technologies, products, services and solutions offered by our competitors. Further, in the process of pursuing broadband licenses, we may be required to make significant concessions or contractual commitments, make significant payments or assume significant costs, purchase additional spectrum or replacement communication systems or limit the use of our spectrum assets or restrict our pursuit of business opportunities to address the concerns expressed by incumbents and other interested parties.

In addition, the FCC and other federal, state and local governmental authorities, or other third parties, 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 FRNA, which the federal government authorized to help accomplish, fund, and oversee the deployment of a dedicated NPSBN. The NPSBN, which is marketed as “FirstNet”, may provide an additional source of competition to utilizing our 900 MHz

Page 26

spectrum assets by our targeted utility and critical infrastructure enterprises. Additionally, in April 2024, T-Mobile announced that it has commenced an auction process to sell its 800 MHz spectrum holdings. This spectrum may be purchased by a consolidated group of utilities or the ultimate buyer of this spectrum may make this spectrum available to our target utility customers.

Some of our competitors, such as Verizon, AT&T, T-Mobile, and EchoStar, have significantly greater pricing flexibility and have taken steps to compete or may decide to compete against us more aggressively. These and other competitors may own or acquire spectrum that directly competes with our 900 MHz spectrum and/or have developed or may develop technologies that directly compete with our solutions. If competitors offer spectrum rights or services, technologies and solutions to our targeted customers at prices and terms that make the licensing of our spectrum assets unattractive, our ability to license or otherwise commercialize our spectrum assets could be impaired. As a result, we may be unable to attract customers at prices or on terms that would be favorable, or at all, which likely would have an adverse effect on the growth and timing of any future revenues. In addition, we may not be able to fund or invest in certain areas of our business to the same degree as our competitors. Several have substantially greater product development and marketing budgets and other financial and regulatory personnel resources than we do. Several also have greater name and brand recognition and a larger base of customers than we have. Competition could increase our selling and marketing expenses and related customer acquisition costs. We may not have the financial resources, technical expertise or marketing and support capabilities to compete successfully.

If we are unable to attract new customers, our results of operations and our business will be adversely affected.

Our targeted customers are large, heavily-regulated enterprises and our business plan requires these customers to commit to long-term transactions for our spectrum and then to purchase and deploy broadband network equipment, solutions and services utilizing our 900 MHz Broadband Spectrum. There are typically a number of constituencies within each of our targeted customers that need to review and approve the commercial agreements of our spectrum before signing a contract with us. As a result, we have experienced, and we expect to continue to experience, long sales cycles with our targeted customers. In addition, numerous other factors, many of which are out of our control, may now or in the future impact our ability to acquire new customers, including not gaining support from governmental bodies that regulate our customers, the ability of our customers to pass their broadband spectrum use and deployment costs to their ratepayers, our customers’ existing commitments to other providers or communication solutions, real or perceived costs of securing our spectrum assets and deploying broadband networks, solutions and services, our failure to expand, retain and motivate our sales and marketing personnel, our failure to develop or expand relationships with the manufacturers or suppliers of broadband technologies, solutions and services that can be utilized on our spectrum, negative media, industry or financial analyst commentary regarding us or our solutions, litigation, the spectrum and service offerings of our competitors, the adverse impacts of the health pandemics and deteriorating general economic conditions and events. Any of these factors could impact our ability to attract new customers to lease or obtain rights to our spectrum assets. As a result of these and other factors, we may be unable to timely attract enough customers to support our operating costs, which would harm our business and results of operations.

We have had net losses each year since our inception and may not achieve or maintain profitability in the future.

We have incurred net losses each year since our inception and we may not achieve or maintain profitability in the future for a number of reasons, including without limitation, the costs to obtain broadband licenses, including the costs to clear the 900 MHz band, the costs to promote and commercialize our spectrum assets to our targeted utility and critical infrastructure customers, our inability to commercialize our spectrum assets to our targeted utility and critical infrastructure customers on a timely basis and on commercially favorable terms and changes in our revenue recognition policies. Additionally, we may encounter unforeseen operating expenses, difficulties, complications, delays and other unknown factors that may result in significant delays in our business plans, levels of revenue below our current expectations, or losses or expenses that exceed our current expectations. If our losses or expenses exceed our expectations or our revenue assumptions are not met in future periods, we may never achieve or maintain profitability in the future.

Our ability to use our net operating losses to offset future taxable income, if any, may be subject to certain limitations.

As of March 31, 2024, we had approximately $66.2 million of federal net operating loss (“NOL”) carryforwards, expiring in various amounts from 2024 through 2037, to offset future taxable income and the remaining $241.1 million of which can be carried forward indefinitely but limited to 80% of future taxable income when used. In the United States, utilization of the NOL carryforwards may be subject to a substantial annual limitation under Section 382 of the Internal Revenue Code of 1986, as amended (the “Code”), and similar state provisions due to ownership change limitations that have occurred previously or that could occur in the future. The NOL carryforwards and certain other tax attributes of ours may also be subject to limitations as a result of ownership changes. If we were to lose the benefits of these NOL carryforwards, our future earnings and cash resources would be materially and adversely affected. We have mainly incurred net losses since our inception, and we anticipate that we will continue to incur significant losses for the foreseeable future; thus, we do not know whether or when we will generate the U.S. federal taxable income necessary to utilize our NOLs.

Page 27

Our reputation and business may be harmed, and we may be subject to legal claims if there is loss, disclosure, or misappropriation of, or access to, our customers’ information.

We make use of online services and centralized data processing, including through third-party service providers. The secure maintenance and transmission of customer information is an important element of our operations. Our information technology and other systems, and those of our service providers or contract partners, that maintain and transmit customer information, including location or personal information, may be compromised by a malicious third-party penetration of our network security, or that of our third-party service providers or contract partners, or impacted by unauthorized intentional or inadvertent actions or inactions by our employees, or by the employees of our third-party service providers or contract partners. Cyber-attacks, which include the use of malware, computer viruses and other means of disruption or unauthorized access, have increased in frequency, scope and potential harm in recent years. While, to date, we have not been subject to cyber-attacks or other cyber incidents which, individually or in the aggregate, have been material to our operations or financial condition, the preventive actions we and our third-party service providers and contract partners take to reduce the risk of cyber incidents and protect information technology resources and networks may be insufficient to repel a major cyber-attack in the future. As a result, our customers’ information may be lost, disclosed, accessed, used, corrupted, destroyed or taken without the customers’ consent. Any significant compromise of our data or network security, failure to prevent or mitigate the loss of customer information and delays in detecting any such compromise or loss could disrupt our operations, impact our reputation and subject us to additional costs and liabilities, including litigation, which could produce material and adverse effects on our business and results of operations.

Risks Related to Our Organization and Structure

We may change our operations and business strategies without stockholder consent.

Our executive management team, with oversight from our Board, establishes our operational plans, our commercialization plans and our business strategies. Our Board and executive management team may make changes to or approve transactions that deviate from our current operations and strategies without a vote of, or prior notice to, our stockholders. This authority to change our operations, commercialization plans and business strategies could result in us conducting operational matters, making investments, pursuing spectrum opportunities, or implementing business or growth strategies in a manner different than those that we are currently pursuing. Under any of these circumstances, we may expose ourselves to different and more significant risks, decrease our revenues or increase our expenses and financial requirements, any of which could have a material adverse effect on our business, prospects, liquidity, financial condition and results of operations.

Our future success depends on our ability to retain our executive officers and key personnel and to attract, retain and motivate qualified personnel.

Our success depends to a significant degree upon the contributions of our executive officers and key personnel, who have unique experience and expertise in the telecommunications industry, large scale and multi-year solution selling to utilities, wireless broadband networks, FCC rulemaking and spectrum retuning and clearing to obtain FCC licenses. Although we have adopted a severance plan for our executive officers, we do not otherwise have long-term employment agreements with any of our executive officers or key personnel. There is no guarantee that these individuals will remain employed with us. In addition, we have not obtained and do not expect to obtain key man life insurance that would provide us with proceeds in the event of the death or disability of any of our executive officers or key personnel. If any of our executive officers or key personnel were to cease employment with us, our operating results and the implementation of our commercial and business terms could suffer. Further, the process of attracting and retaining suitable replacements for our executive officers and key personnel would result in transition costs and would divert the attention of other members of our senior management team from our existing operations. As a result, the loss of services from our executive officers or key personnel or a limitation in their availability could materially and adversely impact our business, customer prospects and results of operations. Further, such a loss could be negatively perceived in the capital markets.

Recruiting and retaining qualified personnel, including effective sales personnel, are critical to our success. Competition to hire qualified personnel in our industry is intense, and we may be unable to hire, train, retain or motivate these key personnel on acceptable terms given the competition among numerous telecommunications, service and infrastructure companies for similar personnel.

We will need to continue to expand our organization and we may experience difficulties in managing this growth, which could disrupt our operations.

We have significantly expanded our commercialization organization since the Report and Order was issued in May 2020. As we continue to pursue broadband licenses and implement our commercialization plans, we expect to need additional managerial, operational, technical, sales, marketing, financial, legal and other resources. Our management may need to divert its attention away from its day-to-day activities and devote a substantial amount of time to managing these growth activities. We may not be able to effectively manage the expansion of our operations, which may result in weaknesses in our infrastructure,

Page 28

operational mistakes, loss of business opportunities, loss of employees and reduced productivity among remaining employees. Our expected growth could require significant expenditures and may divert financial resources from other projects. If our management is unable to effectively manage our growth, our expenses may increase more than expected or budgeted, our ability to generate and/or grow revenue could be reduced and we may not be able to implement our currently anticipated business strategy. Our future financial performance and our ability to commercialize our spectrum assets and compete effectively will depend, in part, on our ability to effectively manage any future growth. Failure to manage this growth could disrupt our business operations and negatively impact our ability to achieve success.

If we fail to implement and maintain an effective system of internal controls, we may not be able to accurately determine our financial results or prevent fraud. As a result, our stockholders could lose confidence in our financial results, which would materially and adversely affect our value and our ability to raise any required capital in the future.

Effective internal controls are necessary for us to provide reliable financial reports and effectively prevent fraud. We have discovered in the past and may discover in the future areas of our internal controls that need improvement or additional documentation.

We cannot be certain that we will be successful in implementing or maintaining effective internal controls for all financial periods. As we grow our business, our internal controls will become more complex, and we will require significantly more resources to ensure our internal controls remain effective. The existence of any material weakness or significant deficiency in the future may require management to devote significant time and incur significant expense to remediate any such material weaknesses or significant deficiencies and management may not be able to remediate any such material weaknesses or significant deficiencies in a timely manner. In addition, the existence of any material weakness in our internal controls could also result in errors in our financial statements that could require us to restate our financial statements, cause us to fail to meet our reporting obligations and cause stockholders to lose confidence in our reported financial information, all of which could materially and adversely affect our value and our ability to raise any required capital in the future.

Risks Related to Our Common Stock

There is no assurance that a robust market in our common stock will develop or be sustained.

Since our common stock began trading on the Nasdaq Stock Market in 2015, we have had limited daily trading volume. We cannot assure you that a more active or liquid trading market for our common stock will develop, or will be sustained if it does develop, either of which could materially and adversely affect the market price of our common stock, our ability to raise capital in the future and the ability of stockholders to sell their shares at the volume, prices and times desired. In addition, the risks and uncertainties related to our ability to obtain broadband licenses and our proposed business strategies makes it difficult to evaluate our business, our prospects and the valuation of our Company, which limits the liquidity and volume of our common stock and may have a material adverse effect on the market price of our common stock.

Our common stock prices may be volatile, which could cause the value of our common stock to decline.

The market price of our common stock may be highly volatile and subject to wide fluctuations. Some of the factors that could negatively affect or result in fluctuations in the market price of our common stock include:

•the timing and costs of securing broadband licenses;

•our ability to enter into contracts with our targeted utility and critical infrastructure customers, on a timely basis or at all;

•the terms of our customer contracts, including pre-payments and our contractual obligations;

•our ability to comply with our obligations, on a timely and cost-effective basis, under our existing customer contracts;

•market reaction to any changes in our business plans or strategies;

•announcements, offerings or actions by our competitors;

•governmental regulations or actions taken by governmental bodies;

•additions or departures of any of our executive officers or key personnel;

•actions by our stockholders;

•speculation in the press or investment community;

•general market, economic and political conditions, including an economic slowdown, inflation or dislocation in the global credit markets;

•our operating performance and the performance of other similar companies;

•changes in accounting principles, judgments or assumptions; and

•passage of legislation or other regulatory developments that adversely affect us or our industry.

Concentration of ownership will limit your ability to influence corporate matters.

Based on our review of publicly available filings as of June 21, 2024, funds affiliated with Owl Creek Asset Management (“Owl Creek”) beneficially owned approximately 29.1%, funds affiliated with Heard Capital LLC owned

Page 29

approximately 9.9%, funds affiliated with GIC Private Limited owned approximately 7.9% of our outstanding common stock and funds affiliated with BlackRock, Inc. owned approximately 6.3%. These four investment firms collectively beneficially own approximately 53.2% of our outstanding shares of common stock. Although we are not aware of any voting arrangements between these stockholders, our significant stockholders can determine (if acting together) or significantly influence: (i) the outcome of any corporate actions submitted by our Board for approval by our stockholders and (ii) any proposals or director nominees submitted by a stockholder. Further, they could place significant pressure on our Board to pursue corporate actions, director candidates and business opportunities they identify. For example, in the fiscal year ended March 31, 2022 (“Fiscal 2022”) we engaged in cooperative discussions with Owl Creek regarding Owl Creek’s interest in nominating an individual to our Board and in Fiscal 2023 we added Jeffrey Altman, managing member of the general partner of Owl Creek, to our Board. In addition, in its recent filings with the SEC, Owl Creek reported that it expects to continue to engage in cooperative discussions with our management and Board concerning ways to work together to achieve our strategic objectives. Owl Creek and our other significant stockholders could effectively block or accept a proposed sale of the company, even if recommended by our Board. Alternatively, these stockholders could place pressure on our Board to pursue a sale of the company or its assets. As a result of this concentration of ownership, our other stockholders may have no effective voice in our corporate actions or the operations of our business, which may adversely affect the market price of our common stock. 

Future sales of our common stock, or preferred stock, or of other securities convertible into our common stock or preferred stock, could cause the market value of our common stock to decline and could result in dilution of your shares.

Our Board is authorized, without stockholder approval, to permit us to issue additional shares of common stock or to raise capital through the creation and issuance of preferred stock, other debt securities convertible into common stock or preferred stock, options, warrants and other rights, on terms and for consideration as our Board in its sole discretion may determine. 

Sales of substantial amounts of our common stock, including sales by our officers, directors or 5% and greater stockholders, or of preferred stock could cause the market price of our common stock to decrease significantly. We cannot predict the effect, if any, of future sales of our common stock, or the availability of our common stock for future sales, on the value of our common stock. Sales of substantial amounts of our common stock by any one or more of our large stockholders, or the perception that such sales could occur, may adversely affect the market price of our common stock.

We cannot guarantee that our share repurchase program will be utilized to the full value approved or that it will enhance long-term stockholder value. Repurchases we consummate could increase the volatility of the price of our common stock and could have a negative impact on our available cash balance.

Our Board authorized a new share repurchase program (the “2023 Share Repurchase Program”) pursuant to which we may repurchase up to $250.0 million of our common stock on or before September 21, 2026. The manner, timing and amount of any share repurchases may fluctuate and will be determined by us based on a variety of factors, including the market price of our common stock, our priorities for the use of cash to support our business operations and plans, general business and market conditions, tax laws, and alternative investment opportunities. The share repurchase program authorization does not obligate us to acquire any specific number or dollar value of shares. Further, our share repurchases could have an impact on our share trading prices, increase the volatility of the price of our common stock, or reduce our available cash balance such that we will be required to seek financing to support our operations. Our share repurchase program may be modified, suspended or terminated at any time, which may result in a decrease in the trading prices of our common stock. Even if our share repurchase program is fully implemented, it may not enhance long-term stockholder value. Additionally, repurchases are subject to the 1% Share Repurchase Excise Tax enacted by the Inflation Reduction Act, which may be offset by shares newly issued during that fiscal year (the “Share Repurchase Excise Tax”). We have and will continue to take the Share Repurchase Excise Tax into account with respect to our decisions to repurchase shares.

Future offerings of debt securities or preferred stock, which would rank senior to our common stock in the event of our bankruptcy or liquidation, may adversely affect the market price of our common stock.

In the future, we may attempt to increase our capital resources by making offerings of debt securities or otherwise incurring debt. In the event of our bankruptcy or liquidation, holders of our debt securities may be entitled to receive distributions of our available assets prior to the holders of our common stock. In addition, we may offer preferred stock that provides holders with a preference on liquidating distributions or a preference on dividend payments or both or that could otherwise limit our ability to pay dividends or make liquidating distributions to the holders of our common stock. Although we have no present plans to do so, our decision to issue debt securities or to issue preferred stock in any future offerings or otherwise incur debt may depend on market conditions and other factors beyond our control. As a result, we cannot predict or estimate the amount, timing or nature of our future offerings, and investors in our common stock bear the risk of our future offerings reducing the market price of our common stock and/or diluting their ownership interest in us.

Page 30

Certain anti-takeover defenses and applicable law may limit the ability of a third party to acquire control of us.

Certain provisions of our amended and restated certificate of incorporation, as amended (the “Amended and Restated Certificate of Incorporation”) and amended and restated bylaws, as amended (the “Amended and Restated Bylaws”), could discourage, delay, or prevent a merger, acquisition, or other change of control that stockholders may consider favorable, including transactions in which you might otherwise receive a premium for your shares. These provisions also could limit the price that investors might be willing to pay in the future for our common stock, thereby depressing the market price of our common stock. These provisions, among other things:

•allow the authorized number of directors to be changed only by resolution of our Board;

•authorize our Board to issue, without stockholder approval, preferred stock, the rights of which will be determined at the discretion of our Board and that, if issued, could operate as a “poison pill” to dilute the stock ownership of a potential hostile acquirer to prevent an acquisition that our Board does not approve;

•establish advance notice requirements for stockholder nominations to our Board or for stockholder proposals that can be acted on at stockholder meetings; and

•limit who may call a stockholders meeting.

In addition, we are subject to Section 203 of the Delaware General Corporation Law (the “DGCL”). In general, Section 203 of the DGCL prevents an “interested stockholder” (as defined in the DGCL) from engaging in a “business combination” (as defined in the DGCL) with us for three years following the date that person becomes an interested stockholder unless one or more of the following occurs:

•before that person became an interested stockholder, our Board approved the transaction in which the interested stockholder became an interested stockholder or approved the business combination;

•upon consummation of the transaction that resulted in the interested stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of our voting stock outstanding at the time the transaction commenced, excluding for purposes of determining the voting stock outstanding (but not the outstanding voting stock owned by the interested stockholder) stock held by directors who are also officers of our Company and by employee stock plans that do not provide employees with the right to determine confidentially whether shares held under the plan will be tendered in a tender or exchange offer; or

•following the transaction in which that person became an interested stockholder, the business combination is approved by our Board and authorized at a meeting of stockholders by the affirmative vote of the holders of at least 66 2/3% of our outstanding voting stock not owned by the interested stockholder.

The DGCL generally defines “interested stockholder” as any person who, together with affiliates and associates, is the owner of 15% or more of our outstanding voting stock or is our affiliate or associate and was the owner of 15% or more of our outstanding voting stock at any time within the three-year period immediately before the date of determination. As a result, our election to be subject to Section 203 of the DGCL could limit the ability of a third party to acquire control of us.

Claims for indemnification by our directors and officers may reduce our available funds to satisfy successful third-party claims against us and may reduce the amount of money available to us.

Our Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws provide that we will indemnify our directors and officers, in each case to the fullest extent permitted by Delaware law. In addition, as permitted by Section 145 of the DGCL, our Amended and Restated Bylaws and our indemnification agreements that we have entered into with our directors and officers provide that:

•we will indemnify our directors and officers for serving us in those capacities or for serving other business enterprises at our request, to the fullest extent permitted by Delaware law. Delaware law provides that a corporation may indemnify such person if such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of the registrant and, with respect to any criminal proceeding, had no reasonable cause to believe such person’s conduct was unlawful;

•we may, in our discretion, indemnify employees and agents in those circumstances where indemnification is permitted by applicable law;

•we are required to advance expenses, as incurred, to our directors and officers in connection with defending a proceeding, except that such directors or officers shall undertake to repay such advances if it is ultimately determined that such person is not entitled to indemnification;

•we will not be obligated pursuant to our Amended and Restated Bylaws to indemnify a person with respect to proceedings initiated by that person against us or our other indemnities, except with respect to proceedings authorized by our Board or brought to enforce a right to indemnification;

•the rights conferred in our Amended and Restated Bylaws are not exclusive, and we are authorized to enter into indemnification agreements with our directors, officers, employees and agents and to obtain insurance to indemnify such persons; and

•we may not retroactively amend our bylaw provisions to reduce our indemnification obligations to directors, officers, employees and agents.

As a result, claims for indemnification by our directors and officers may reduce our available funds to satisfy successful third-party claims against us and may reduce the amount of money available to us.

ITEM 1B. UNRESOLVED STAFF COMMENTS

None.

ITEM 1C. CYBERSECURITY

We have implemented and we maintain a cybersecurity program that includes a well-defined set of security controls and measures designed to identify, assess, and manage material cybersecurity risks. The cybersecurity program is a part of our broader enterprise risk management program which includes risk assessment, third party risk management, risk mitigation strategy and a clearly defined incident response methodology. The program is led by our executive officers, with support from a working group of senior management with functional and operational expertise. Oversight for this program is provided by the Audit Committee of the Board. Each quarter our executive officers review matters, including any cybersecurity matters, that may present material risks to our strategy, mission or objectives, and where appropriate, engage third parties to conduct assessments of the risks and gaps that require attention. Risk events are classified based on the evaluated likelihood of the risk materializing and its potential impact on the enterprise, and for each material risk a definitive risk mitigation strategy is developed, executed, and shared with the Audit Committee and the Board by our Chief Legal Officer and Corporate Secretary, working closely with our Chief Financial Officer and head of Information Technology, at least quarterly to ensure appropriate monitoring and management of the relevant risks. To date, based upon all evaluations and assessments, including third party evaluations, we have no cybersecurity threats that have materially affected, or are reasonably likely to materially affect, our business strategy, operations or financial condition.

ITEM 2. PROPERTIES

We maintain offices in Woodland Park, New Jersey, McLean, Virginia and Abilene, Texas. The lease for our corporate headquarters at 3 Garret Mountain Plaza, Suite 401, Woodland Park, New Jersey, which was renewed in February 2017 for an additional 10 years, is for 19,276 square feet of office space with a termination date of June 2027. We have the right of first offer for adjacent space if it becomes available. In February 2019, we entered into a lease agreement for our second office space located at 8260 Greensboro Drive, Suite 501, McLean, Virginia for 5.5 years, which was amended in September 2022 to expand the office by an additional 2,847 square feet for a total of 8,212 square feet with a termination date of October 2024. In November 2018, we entered into a lease agreement to store equipment located at 5520 North First Street, Abilene, Texas for 5 years with a termination date of January 2029. The leased warehouse includes approximately 37,409 square feet. We believe that our existing facilities are adequate for our current needs.

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following management’s discussion and analysis of financial condition and results of operations should be read in conjunction with our historical consolidated financial statements and the related notes. This management’s discussion and analysis contains forward-looking statements that involve risks and uncertainties, such as statements of our plans, objectives, expectations and intentions. Any statements that are not statements of historical fact are forward-looking statements. These forward-looking statements are subject to risks and uncertainties that could cause our actual results or events to differ materially from those expressed or implied by the forward-looking statements. Factors that could cause or contribute to such differences include, but are not limited to, those identified below and those discussed in the section entitled “Risk Factors” included elsewhere in this Annual Report. Except as required by applicable law we do not undertake any obligation to update forward-looking statements to reflect events or circumstances occurring after the date of this Annual Report.

This management’s discussion and analysis of financial condition and results of operations is based on our consolidated financial statements, which we have prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The preparation of these financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements, as well as the reported revenues and expenses during the reporting periods. On an ongoing basis, we evaluate such estimates and judgments, including those described in greater detail below. We base our estimates on historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Our actual results may differ from these estimates under different assumptions or conditions.

Summary.

Our net loss for Fiscal 2024 decreased by approximately $7.2 million, or -44%, to $9.1 million from $16.3 million in Fiscal 2023. The decrease in net loss was primarily due to the following:

•Operating revenues increased by $2.3 million, or 118%, to $4.2 million in Fiscal 2024 from $1.9 million in Fiscal 2023. The increase in our spectrum lease revenue was attributable to revenue recognized in connection with our agreements with Evergy and Xcel Energy of approximately $0.4 million and $1.9 million, respectively, for the current year. For a discussion of our revenue recognition policy, refer to Note 2 Summary of Significant Accounting Policies in the Notes to the Consolidated Financial Statements contained within this Annual Report.

•Product development expenses increased by $1.3 million, or 28%, to $5.7 million for Fiscal 2024 from $4.4 million for Fiscal 2023. The increase primarily resulted from $1.0 million higher non-recurring engineering fees related to developing next generation chipsets for band 106 ecosystem, $0.6 million higher head count and related costs, $0.1 million higher professional services, partially offset by $0.2 million lower contract consulting costs and $0.2 million lower stock compensation expense due to fewer grants.

•Gain from disposal of intangible assets, net decreased by $3.4 million, or -9%, to $35.0 million for Fiscal 2024 from $38.4 million for Fiscal 2023. During Fiscal 2024, we exchanged our narrowband licenses for broadband licenses in 28 counties. In connection with the exchange, we recorded an estimated accounting cost basis of $43.7 million for the new broadband licenses and relinquished to the FCC narrowband licenses for those same 28 counties valued at $8.7 million. As a result, we recorded a $35.0 million non-monetary gain from disposal of the intangible assets on our Consolidated Statements of Operations. Refer to Note 6 Intangible Assets in the Notes to the Consolidated Financial Statements contained within this Annual Report for further discussion on the exchanges.

•Gain on sale of intangible assets, net increased by $7.4 million, or 100%, to $7.4 million for Fiscal 2024 from zero for Fiscal 2023. During Fiscal 2024, we transferred to SDG&E the Imperial County broadband license and the San Diego County broadband license and recorded a cumulative $7.4 million gain on sale of intangible assets on our Consolidated Statements of Operations. As part of the SDG&E Agreement, SDG&E has an option to pursue additional spectrum with us. In accordance with Accounting Standards Codification Topic 606, Revenue from Contracts with Customers, we recorded a cumulative $4.9 million deferred gain on sale of intangible assets on our Consolidated Balance Sheets as of March 31, 2024, related to this option, which expires within 5 years of each delivery date. Refer to Note 6

Page 37

Intangible Assets in the Notes to the Consolidated Financial Statements contained within this Annual Report for further discussion on the sale of intangible assets.

•Interest income increased by $1.2 million, or 108%, to $2.4 million for Fiscal 2024 as compared to $1.1 million from Fiscal 2023. The increase was primarily attributable to higher interest rates and higher cash balance.

Liquidity and Capital Resources 

Our principal source of liquidity is our cash and cash equivalents generated from customer contract proceeds. At March 31, 2024, we had cash and cash equivalents of $60.6 million.

We believe our cash and cash equivalents on hand, along with contracted proceeds from customers, will be sufficient to meet our financial obligations through at least 12 months from the date of this Annual Report. As noted above, our future capital requirements will depend on a number of factors, including among others, future customer contracts, the costs and timing of our spectrum retuning activities, spectrum acquisitions and the Anti-Windfall Payments to the U.S. Treasury, our operating activities, any cash proceeds we generate through our commercialization activities, our ability to timely deliver broadband licenses to our customers in accordance with our contractual obligations and our obligation to refund payments or pay penalties if we do not meet our commercial obligations. We deploy this capital at our determined pace based on several key ongoing factors, including customer demand, market opportunity, and offsetting income from spectrum leases. We cannot reasonably estimate any potential impact to our results of operations, commercialization efforts and financial condition arising from changes to our macroeconomic, legal or regulatory environment, including potential legislation affecting the energy or utility industry, the telecommunications environment, or supply chains. We are actively managing our business to maintain our cash flow and believe that we currently have adequate liquidity. To implement our business plans and initiatives, however, we may need to raise additional capital. We cannot predict with certainty the exact amount or timing for any future capital raises. See “Risk Factors” in Item 1A of Part I of this Annual Report for a reference to the risks and uncertainties that could cause our costs to be more than we currently anticipate and/or our revenue and operating results to be lower than we currently anticipate. If required, we intend to raise additional capital through debt or equity financing or through some other financing arrangement. However, we cannot be sure that additional financing will be available if and when needed, or that, if available, we can obtain financing on terms favorable to our stockholders and to us. Any failure to obtain financing when required will have a material adverse effect on our business, operating results, financial condition and liquidity.

Cash Flows from Operating, Investing and Financing Activities

	For the years ended March 31,
(in thousands)	2024		2023
Net cash provided by (used in) operating activities	$	41,993	$	(27,250)
Net cash provided by (used in) investing activities	$	8,089	$	(27,130)
Net cash used in financing activities	$	(25,140)	$	(8,062)

Net cash provided by (used in) operating activities

Our principal source of cash provided by operating activities is our customer contract proceeds in the form of advanced payments. For spectrum lease agreements, we record these advanced payments as deferred revenue on our Consolidated Balance Sheets and recognize revenue over the term of the lease, which is typically 20 to 30 years. For spectrum sale agreements, we record advanced payments as a contingent liability on our Consolidated Balance Sheets and derecognize this liability upon closing of the sale along with recording a gain or loss on sale. In addition, our cash flows reflect a non-cash gain or loss on disposal of intangible assets for the difference in cost basis as we exchange narrowband licenses for broadband licenses. We expect net cash provided by (used in) operating activities to be affected by the progress on our customer agreements as well as changes in other operating assets and liabilities. The following represents our changes in net cash provided by (used in) operating activities for Fiscal 2024 and Fiscal 2023.

Net cash provided by operating activities was approximately $42.0 million in Fiscal 2024. The net cash provided by operating activities in Fiscal 2024 was primarily due to the following:

• $61.5 million increase in deferred revenue due to $66.0 million cash proceeds from our 900 MHz Broadband Spectrum customer prepayments offset by $4.2 million in revenue recognition in connection with the delivery of cleared 900 MHz Broadband Spectrum;

•$15.0 million increase in contingent liability related to the LCRA Agreement; and

•$9.1 million decrease related to our operating loss, which includes $23.6 million of non-cash items. Refer to the Results of Operations.

Page 38

Net cash used in operating activities was approximately $27.3 million in Fiscal 2023. The net cash used in operating activities in Fiscal 2023 was primarily due to the following:

•$6.1 million increase in deferred revenue due to $8.0 million cash proceeds from our 900 MHz Broadband Spectrum customer prepayments offset by $1.9 million in revenue recognition in connection with the delivery of cleared 900 MHz Broadband Spectrum.

•$0.2 million increase in contingent liability related to the SDG&E Agreement; and

•$16.3 million decrease related to our operating loss, which includes $17.2 million of non-cash items. Refer to the Results of Operations.

Net cash provided by (used in) investing activities

Our principal outflow of cash used in investing activities is our purchases of intangible assets, including refundable deposits, retuning costs and swaps, which represent our spectrum clearing efforts as we work toward the conversion from narrowband to broadband spectrum. The purchases of intangible assets may be offset by current period cash proceeds from the sale of intangible assets, with a potential non-cash derecognition of the contingent liability for any proceeds received and recognized in operating activities in a prior period. We expect net cash provided by (used in) investing activities to be affected by the timing of our spectrum clearing efforts and the closing of our sale transactions and the related transfer of broadband licenses. The following represents our changes in net cash provided by (used in) investing activities for Fiscal 2024 and Fiscal 2023.

Net cash provided by (used in) investing activities was approximately $8.1 million and $27.1 million in Fiscal 2024 and Fiscal 2023 respectively. For Fiscal 2024, the net cash provided by investing activities resulted from $25.4 million sale of spectrum related to our transfer of the San Diego County and Imperial County broadband license to SDG&E, offset by $17.0 million in payments made to acquire, swap or retune wireless licenses in markets across the United States and $0.3 million for purchases of equipment. For Fiscal 2023, the net cash used in investing activities resulted from $25.0 million in payments made to acquire, swap or retune wireless licenses in markets across the United States and $2.1 million for purchases of equipment.

Net cash used in financing activities

Our principal outflow of cash used in financing activities is a result of our equity transactions, including repurchases of common stock and taxes and fees associated with the issuance of restricted stock awards, offset by proceeds from stock options exercised in the period. We expect net cash used in financing activities to be affected by the timing of future equity transactions including the timing of our repurchases of common stock. The following represents our changes in net cash used in financing activities for Fiscal 2024 and Fiscal 2023.

Net cash used in financing activities was approximately $25.1 million and $8.1 million in Fiscal 2024 and Fiscal 2023, respectively. For Fiscal 2024, net cash used in financing activities was primarily from the repurchase of common stock of $24.7 million, payments of withholding tax on net issuance of restricted stock of $1.2 million, partially offset by the proceeds from stock option exercises of $0.8 million. For Fiscal 2023, net cash used in financing activities was primarily from the repurchase of common stock of $8.2 million, payments of withholding tax on net issuance of restricted stock of $1.6 million, partially offset by the proceeds from stock option exercises of $1.7 million.

The following table illustrates the estimated contracted customer proceeds for Fiscal 2025 and thereafter (in thousands):

Customers	Fiscal 2025*		Thereafter*

* Total cash proceeds are subject to change based on final delivery date of the broadband licenses for the associated milestone, which may include penalties associated with delayed deliveries.

Material Cash Requirements

Our future capital requirements will depend on many factors, including: costs and time related to the commercialization of our spectrum assets; and our ability to sign customer contracts and generate revenues from the license or transfer of any broadband licenses we secure; our ability to timely deliver broadband licenses and clear spectrum to our

Page 39

customers in accordance with our contractual obligation; any requirement to refund payments or pay penalties if we do not satisfy our contractual obligations; the timeline and costs to acquire broadband licenses pursuant to the Report and Order, including the costs to acquire additional spectrum, the costs related to retuning, or swapping spectrum held by 900 MHz site-based licensees in the broadband segment that is required under section 90.621(b) to be protected by a broadband licensee with a base station at any location within the county, or any 900 MHz geographic-based SMR licensee in the broadband segment whose license area completely or partially overlaps the county, and the costs of paying Anti-Windfall Payments to the U.S. Treasury.

We are obligated under certain lease agreements for office space with lease terms expiring on various dates from October 31, 2024 through January 31, 2029, which includes a three to ten-year lease extension for our corporate headquarters. We have also entered into multiple lease agreements for tower space related to its spectrum holdings. The lease expiration dates range from April 30, 2024 to March 21, 2031. Total estimated payments for these lease agreements are approximately $6.1 million (exclusive of real estate taxes, utilities, maintenance and other costs borne by us). We also have an obligation to clear the tower site locations, for which we recorded an asset retirement obligation (the “ARO”). Total estimated payments as a result of the ARO are approximately $0.7 million. See Note 2 Summary of Significant Accounting Policies in the Notes to the Consolidated Financial Statements contained within this Annual Report for further information on the AROs. In addition to the lease payments and ARO for our tower site locations, we entered into agreements with several third parties in multiple U.S. markets to acquire, retune or swap wireless licenses for cash consideration (“deals”). As of March 31, 2024, our total estimated payments for these agreements with incumbents are approximately $17.9 million.

Xcel Energy Guaranty

In October 2022, we entered into an agreement with Xcel Energy providing Xcel Energy dedicated long-term usage of our 900 MHz Broadband Spectrum for a term of 20 years throughout Xcel Energy’s service territory in eight states the Xcel Energy Agreement. In connection with Xcel Energy Agreement, we entered into a guaranty agreement, under which we guaranteed the delivery of the relevant 900 MHz Broadband Spectrum and the associated broadband licenses in Xcel Energy’s service territory in eight states along with other commercial obligations. In the event of default or non-delivery of the specific territory’s 900 MHz Broadband Spectrum, we are required to refund payments we have received. In addition, to the extent Anterix has performed any obligations, our liability and remaining obligations under the Xcel Energy Agreement will extend only to the remaining unperformed obligations. We recorded $67.1 million in deferred revenue in connection with the prepayments received as of March 31, 2024. We commenced delivery of the relevant cleared 900 MHz Broadband Spectrum and the associated broadband leases in the first quarter of fiscal year 2024 and will continue through 2029. The revenue recognized for the year ended March 31, 2024 was approximately $1.9 million. As of March 31, 2024, the maximum potential liability of future undiscounted payments under this agreement is approximately $65.2 million.

Share Repurchase Program

In September 2021, our Board authorized a share repurchase program (the “2021 Share Repurchase Program”) pursuant to which we may repurchase up to $50.0 million of our common stock on or before September 29, 2023. We repurchased and subsequently retired a total of $33.9 million of our common stock under the 2021 Share Repurchase Program, including $10.7 million during fiscal year 2024. On September 21, 2023, our Board authorized the new 2023 Share Repurchase Program pursuant to which we may repurchase up to $250.0 million of our common stock on or before September 21, 2026. We repurchased and subsequently retired a total of $13.9 million of our common stock under the 2023 Share Repurchase Program during fiscal year 2024. We may repurchase shares of our common stock via the open market and/or privately negotiated transactions. Repurchases will be made in accordance with applicable securities laws and may be effected pursuant to Rule 10b5-1 trading plans. The manner, timing and amount of any share repurchases will be determined by us based on a variety of factors, including, proceeds from customer contracts, the timing of which is unpredictable, as well as general business and market conditions, our capital position and other strategic considerations. The 2023 Share Repurchase Program does not obligate us to repurchase any particular amount of our common stock.

The Inflation Reduction Act of 2022, which was enacted into law on August 16, 2022, imposed a nondeductible 1% excise tax on the net value of certain stock repurchases made after December 31, 2022. Excise tax accrued for the year ended March 31, 2024 was approximately $0.2 million.

Critical Accounting Estimates 

The accompanying consolidated financial statements have been prepared in accordance with U.S. GAAP, which require management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Accordingly, our actual results could differ from those based on such estimates and assumptions. Further, to the extent that there are differences between our estimates and our actual results, our future financial statement presentation, financial condition, results of operations and cash flows will be affected. We believe that the accounting policies discussed below are critical to understanding our historical performance, as these policies relate to the more significant areas involving our judgments and estimates.

We believe that the areas described below are the most critical to aid in fully understanding and evaluating our reported financial results, as they require management’s significant judgments in the application of accounting policy or in making estimates and assumptions that are inherently uncertain and that may change in subsequent periods. Our significant accounting policies are set forth in Note 2 Summary of Significant Accounting Policies in the Notes to the Consolidated Financial Statements contained within this Annual Report. Of those policies, we believe that the policy discussed below may involve a higher degree of judgment and may be more critical to an accurate reflection of our financial condition and results of operations.

Evaluation of Indefinite-Lived Intangible Assets for Impairment

Unit of accounting of wireless licenses not associated with closed deals is based on geographic markets. Unit of accounting of wireless licenses associated with closed deals is based on the deal markets. Our wireless licenses not associated with closed deals are tested for impairment based on the geographic markets, as we will be utilizing the existing wireless narrowband licenses, or broadband licenses if applicable, as part of facilitating broadband spectrum networks at a geographic market level. Our wireless licenses associated with closed deals are tested for impairment based at the deal market level. We use a market-based approach to estimate fair value for impairment testing purposes. We may elect to first perform a qualitative assessment to determine whether it is more likely than not that the fair value of an intangible asset is less than its carrying value. If we do not perform the qualitative assessment, or if the qualitative assessment indicates it is more likely than not that the fair value of the intangible asset is less than its carrying amount, we will calculate the estimated fair value of the intangible asset. If the estimated fair value of the spectrum licenses is lower than their carrying amount, an impairment loss is recognized. We will use a market-based approach to estimate fair value for impairment testing purposes except for deals that were realized as of the valuation date, for which a transaction specific market approach will be used.

The valuation approach used to estimate fair value for the purpose of impairment testing requires management to use complex assumptions and estimates such as population, discount rates, industry and market considerations, long-term market equity risk, as well as other factors. These assumptions and estimates depend on our ability to accurately predict forward looking assumptions including successfully applying for broadband licenses, commercializing our 900 MHz Broadband Spectrum and properly estimating favorable deal terms over the life of the contract. For impairment testing, estimated fair value is determined using a market-based approach primarily using the 600 MHz auction price. The FCC will use the spectrum price based on the average price paid in the FCC’s 600 MHz auction to calculate the Anti-Windfall Payments. The estimated fair value of realized deals is determined using a transaction specific market approach based on the deal specific terms and adjusted for our rate of return and present value taking into consideration the timing of payments. In addition, we performed a sensitivity analysis to recent auctions and transactions noting that while in some cases the value was lower than the 600 MHz auction price, the values were well above our carrying value. Furthermore, if management determines that for impairment testing purposes, the 600 MHz auction price is not the appropriate market-based fair value, and the new estimated fair value is lower by over 50%, our intangible assets would still not be impaired as the current estimated fair value for impairment testing purposes exceeds book value by more than 50%.

Page 41

During the years ended March 31, 2024 and 2023, we performed a step one quantitative approach impairment test as of January 1, 2024 and January 1, 2023, respectively, to determine if the fair value of the combined licenses by the associated geographical or deal market exceeds the carrying value for each geographical or deal market. During Fiscal 2023, we shifted from a probability analysis approach to a more detailed approach with measurable qualitative metrics. The new approach, Demonstrated Intent (“DI”), determines how likely a deal is to close based on certain qualitative factors, like applying for an experimental license, entering into a request for proposal, joining certain utility board or publicly backing 900 MHz Broadband Spectrum and its application. As a result, we will continue to utilize the DI scores on a go-forward basis for our impairment analysis. Based on the results of the impairment test, there were no impairment charges recorded during the year ended March 31, 2024 and 2023.

Recent Accounting Pronouncements

Information regarding recent accounting pronouncements, including those recently adopted, is provided in Note 2 Summary of Significant Accounting Policies in the Notes to the Consolidated Financial Statements contained within this Annual Report.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Interest Rate Risk

Our financial instruments consist of cash, cash equivalents, trade accounts receivable and accounts payable. We consider investments in highly liquid instruments purchased with original maturities of 90 days or less to be cash equivalents. Our primary exposure to market risk is interest income sensitivity, which is affected by changes in the general level of U.S. interest rates. However, because of the short-term nature of the highly liquid instruments in our portfolio, a 10% change in market interest rates would not be expected to have a material impact on our financial condition and/or results of operations.

Foreign Currency Exchange Rate Fluctuations

Our operations are based in the United States and, accordingly, all of our transactions are denominated in U.S. dollars. We are currently not exposed to market risk from changes in foreign currency.

Inflation Risk

Inflationary factors may adversely affect our operating results. As a result of recent increases in inflation, certain of our operating expenses have increased. Additionally, although difficult to quantify, we believe that the current macroeconomic environment, including inflation, could have an adverse effect on our target customers’ businesses, which may harm our commercialization efforts and negatively impact our revenues. Continued periods of high inflation could have a material adverse effect on our business, operating results and financial condition if we are not able to control our operating costs or if our commercialization efforts are slowed or negatively impacted, continued periods of high inflation could have a material adverse effect on our business, operating results and financial condition.

We continue to monitor our market risk exposure, including any adverse impacts related to health pandemics or the current macroeconomic environment, which has resulted in significant market volatility.

ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

The financial statements required by this item are set forth in Item 15 on pages F-2 through F-27 and are filed as part of this Annual Report.

ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE

None.

ITEM 9A. CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

We maintain disclosure controls and procedures designed to ensure that information required to be disclosed in our reports filed pursuant to the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and that such information is accumulated and communicated to our management, including our President and Chief Executive Officer and our Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

Under the supervision and with the participation of our management, including our President and Chief Executive Officer and our Chief Financial Officer, we conducted an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures, as such term is defined in Rule 13a-15(e) of the Exchange Act. Based upon that evaluation,

Page 42

our Principal Executive Officer and Principal Financial and Accounting Officer have concluded that the Company’s disclosure controls and procedures, as defined in Rule 13a-15(e) of the Exchange Act, were effective as of the end of the period covered by this Annual Report.

Management’s Annual Report on Internal Control over Financial Reporting 

Our management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rule 13a-15(f) of the Exchange Act.

Internal control over financial reporting is a process designed under the supervision and with the participation of our management, including our Principal Executive Officer and Principal Financial and Accounting Officer, to provide reasonable assurance regarding the reliability of our financial reporting and the preparation of our financial statements for external purposes in accordance with U.S. GAAP.

Our management, under the supervision of our President and Chief Executive Officer and our Chief Financial Officer, conducted an assessment of the effectiveness of our internal control over financial reporting based on the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control—Integrated Framework. Based on this assessment, our management determined that, as of March 31, 2024, we maintained effective internal control over financial reporting.

Attestation Report on Internal Control over Financial Reporting 

Our management’s report was not subject to attestation by our registered public accounting firm pursuant to the rules of the SEC that exempt certain smaller reporting companies, as that term is defined in Rule 12-b2 of the Exchange Act, from such requirement.

Changes in Internal Control over Financial Reporting 

There were no changes in our internal control over financial reporting, as defined in Rules 13a-15(f) or 15d-15(d) of the Exchange Act, during the quarterly period ended March 31, 2024 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Inherent Limitations on Effectiveness of Controls 

Our management, including our President and Chief Executive Officer and our Chief Financial Officer, do not expect that our disclosure controls or our internal control over financial reporting will prevent or detect all error and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system’s objectives will be met. The design of a control system must reflect the fact that there are resource constraints and that the benefits of controls must be considered relative to their costs. Further, because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud, if any, have been detected.

These inherent limitations include the realities that judgments in decision-making can be faulty and that breakdowns can occur because of simple error or mistake. Controls can also be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the controls. The design of any system of controls is based in part on certain assumptions about the likelihood of future events and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Projections of any evaluation of the effectiveness of controls to future periods are subject to risks. Over time, controls may become inadequate because of changes in conditions or deterioration in the degree of compliance with policies or procedures.

ITEM 9B. OTHER INFORMATION

Report of Independent Registered Public Accounting Firm

Board of Directors and Stockholders

Anterix Inc.

Opinion on the financial statements

We have audited the accompanying consolidated balance sheets of Anterix Inc. (a Delaware corporation) and subsidiaries (the “Company”) as of March 31, 2024 and 2023, the related consolidated statements of operations, stockholders’ equity, and cash flows for each of the two years in the period ended March 31, 2024, and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of March 31, 2024 and 2023, and the results of its operations and its cash flows for each of the two years in the period ended March 31, 2024, in conformity with accounting principles generally accepted in the United States of America.

Basis for opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical audit matters

Critical audit matters are matters arising from the current period audit of the financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. We determined that there are no critical audit matters.

/s/ GRANT THORNTON LLP

We have served as the Company’s auditor since 2019.

Notes to Consolidated Financial Statements

1. Nature of Operations

Anterix Inc ( the “Company”) is the utility industry’s partner, empowering enhanced visibility, control and security for a modern grid. The Company’s vision is to deliver secure, scalable solutions enabled by private wireless broadband connectivity, for the benefit of utilities and the communities that they serve. As the largest holder of licensed spectrum in the 900 MHz band (896-901/935-940 MHz) throughout the contiguous United States, plus Hawaii, Alaska and Puerto Rico, the Company is uniquely positioned to deliver solutions that support secure, resilient and customer-controlled operations. The Company is focused on commercializing its spectrum assets and expanding the benefits and solutions it offers to enable the Company’s targeted utility and critical infrastructure customers to deploy private broadband networks.

The Company was originally incorporated in California in 1997 and reincorporated in Delaware in 2014. In November 2015, the Company changed its name from Pacific DataVision, Inc. to pdvWireless, Inc. In August 2019, the Company changed its name from pdvWireless, Inc. to Anterix Inc. The Company maintains offices in Woodland Park, New Jersey, McLean, Virginia and Abilene, Texas.

Business Developments

TECO Agreement

In November 2023, the Company entered into an agreement with Tampa Electric Company (“TECO”) to provide TECO the use of the Company’s 900 MHz Broadband Spectrum for a term of 20 years throughout TECO’s service territory in West Central Florida (the “TECO Agreement”). The TECO Agreement also provides TECO an option to extend the agreement for two 10-year terms for additional payments. The TECO Agreement, which covers an approximately 2,000-square-mile service territory in West Central Florida, is expected to enable TECO to deploy a PLTE network providing critical broadband communications capabilities in support of its initiatives. The scheduled prepayments for the 20-year initial term of the TECO Agreement total $34.5 million, of which $6.9 million was received by the Company in December 2023. See Note 3 Revenue for further discussion on the TECO Agreement.

LCRA Agreement

In April 2023, the Company entered into an agreement with Lower Colorado River Authority (“LCRA”) to sell 900 MHz Broadband Spectrum covering 68 counties and more than 30 cities in LCRA’s wholesale electric, transmission, and water service area (the “LCRA Agreement”) for total payments of $30.0 million plus the contribution of select LCRA 900 MHz narrowband spectrum. Total consideration of $30.0 million is to be paid through fiscal year 2026 pursuant to the terms of the LCRA Agreement. During the year ended March 31, 2024, the Company received an initial $15.0 million payment, of which $7.5 million was deposited in an escrow account (refer to Note 4 Escrow Deposits for further discussion). See Note 13 Contingencies and Guaranty for further discussion on the LCRA Agreement.

Xcel Energy Agreement

In October 2022, the Company entered into an agreement with Xcel Energy Services Inc. (“Xcel Energy”) providing Xcel Energy dedicated long-term usage of the Company’s 900 MHz Broadband Spectrum for a term of 20 years throughout Xcel Energy’s service territory in eight states (the “Xcel Energy Agreement”) for a total of $80.0 million, of which $8.0 million was received by the Company in December 2022. In July 2023 and November 2023, the Company delivered the cleared 900 MHz Broadband Spectrum and the associated broadband leases and received milestone payments of $21.2 million in each period. During the year ended March 31, 2024, the Company delivered the cleared 900 MHz Broadband Spectrum and the associated broadband leases and received a milestone payment of $16.8 million in January 2024. The revenue recognized for the year ended March 31, 2024, was approximately $1.9 million.

SDG&E Agreement

In February 2021, the Company entered into an agreement with San Diego Gas & Electric Company, a subsidiary of Sempra Energy (“SDG&E”), to sell 900 MHz Broadband Spectrum throughout SDG&E’s California service territory, including San Diego and Imperial Counties and portions of Orange County (the “SDG&E Agreement”) for a total payment of $50.0 million. The total payment of $50.0 million is comprised of an initial payment of $20.0 million received in February 2021 and the remaining payments which are due as the Company delivers the relevant cleared 900 MHz Broadband Spectrum and the associated broadband licenses to SDG&E. In September 2023, the Company transferred to SDG&E the San Diego County broadband license and received a milestone payment of $25.2 million net of delivery delay adjustments of $1.1 million. In December 2023, the Company transferred to SDG&E the remainder of the cleared 900 MHz Broadband Spectrum and the associated broadband license related to Imperial County and received a milestone payment of $0.2 million. See Note 6 Intangible Assets for further discussion.

2023 Stock Plan

On August 8, 2023, the Company adopted a new equity-based compensation plan known as the Anterix Inc. 2023 Stock Plan (the “2023 Stock Plan”). The 2023 Stock Plan permits the Company to grant equity compensation awards to employees, consultants and non-employee directors of the Company. See Note 11 Stock Compensation for further discussion.

2023 Share Repurchase Program

On September 21, 2023, the Board of Directors (the “Board”) authorized a new share repurchase program (the “2023 Share Repurchase Program”) pursuant to which the Company may repurchase up to $250.0 million of the Company’s common stock on or before September 21, 2026. See Note 11 Stock Compensation for further discussion.

2. Summary of Significant Accounting Policies

Basis of Presentation and Use of Estimates

The consolidated financial statements and accompanying notes are prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”), which require management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The most significant estimates relate to estimated useful lives of depreciable assets, asset retirement obligations, valuation allowance on the Company’s deferred tax assets and recoverability of intangible assets. The Company is also required to make certain estimates with regard to the valuation of awards and forfeiture rates for its share-based award programs. Estimates and assumptions are reviewed periodically, and the effects of revisions are reflected in the financial statements in the applicable period. Accordingly, actual results could materially differ from those estimates.

The accompanying consolidated financial statements include the accounts of the Company and its subsidiaries, including PDV Spectrum Holding Company, LLC formed in April 2014. All significant intercompany accounts and transactions have been eliminated in consolidation.

Cash and Cash Equivalents and Restricted Cash

All highly liquid investments with maturities of three months or less at the time of purchase are considered cash equivalents. Cash equivalents are stated at cost, which approximates the quoted market value and includes amounts held in money market funds. Restricted cash includes amounts classified as escrow deposits.

Concentration of Credit Risk and Significant Customers

Financial instruments which potentially expose the Company to concentrations of credit risk consist primarily of cash and cash equivalents. The Company places its cash and temporary cash investments with financial institutions for which credit loss is not anticipated. As of March 31, 2024 and 2023, substantially all of the Company’s cash balance exceeded the federally insured limits. During the year ended March 31, 2024 and 2023, each of the Company’s customers accounted for greater than 10% of total revenue.

As of March 31, 2024 and March 31, 2023, the Company does not have an outstanding accounts receivable balance.

Allowance for Credit Losses

An allowance for credit losses is estimated, as required, based on a combination of write-off history, aging analysis and forecasts on the collectability of accounts receivable. The Company reviews its allowance for credit losses on a quarterly basis. Past due balances meeting specific criteria are reviewed individually for collectability.

Property and Equipment

Property and equipment are stated at cost. Depreciation is computed using the straight-line method over the shorter of the estimated useful lives of the assets or the applicable lease term. The carrying amount at the balance sheet date of long-lived assets under construction in process includes assets purchased, constructed, or being developed internally that are not yet in service. Depreciation commences when the assets are placed in service. Depreciation rates for assets are updated periodically to account for changes, if any, in the estimated useful lives of the assets, lease terms, management’s strategic objectives, estimated residual values or obsolescence. Changes in estimates will result in adjustments to depreciation expense prospectively.

Accounting for Asset Retirement Obligations

An asset retirement obligation is evaluated and recorded as appropriate on assets for which the Company has a legal obligation to retire. The Company records a liability for an asset retirement obligation and the associated asset retirement cost at the time the underlying asset is acquired and put into service. Subsequent to the initial measurement of the asset retirement obligation, the obligation is adjusted at the end of each period to reflect the passage of time and changes in the estimated future

Page F- 8

cash flows underlying the obligation, if any. Over time, the liability is accreted to its present value and the capitalized cost is depreciated over the estimated useful life of the asset.

The Company entered into long-term leasing arrangements primarily for tower site locations. The Company constructed assets at these locations and, in accordance with the terms of many of these agreements, the Company is obligated to restore the premises to their original condition at the conclusion of the agreements, generally at the demand of the other party to these agreements. The Company recognizes the fair value of a liability for an asset retirement obligation and capitalizes that cost as part of the cost basis of the related asset, depreciating it over the useful life of the related asset. Upon settlement of the obligation, any difference between the cost to retire the asset and the recorded liability is recognized on the Company’s Consolidated Statements of Operations.

As of March 31, 2024, the Company did not settle any of its obligations to restore the leased premises to its original condition and increased its asset retirement obligations accrual by $0.1 million based on estimated future cash flows.

As of March 31, 2023, the Company settled approximately $0.1 million of its obligation to restore the leased premises to its original condition and decreased its asset retirement obligations accrual by $6 thousand based on estimated future cash flows.

Changes in the liability for the asset retirement obligations for the years ended March 31, 2024 and 2023 are summarized below (in thousands):

	2024		2023
Balance at beginning of the year	$	543	$	626
Liabilities settled	—		(79)
Revision of estimate	85		(6)
Accretion expense	4		2
Balance at end of the year	632		543
Less amount classified as current - included in accounts payable and accrued expenses	101		30
Noncurrent liabilities - included in other liabilities	$	531	$	513

Intangible Assets

Intangible assets are wireless licenses that are used to provide the Company with the exclusive right to utilize designated radio frequency spectrum to provide wireless communication services. While licenses are issued for only a fixed time, generally ten years, such licenses are subject to renewal by the FCC. License renewals have occurred routinely and at nominal cost in the past. There are currently no legal, regulatory, contractual, competitive, economic or other factors that limit the useful life of the Company’s wireless licenses. As a result, the Company has determined that the wireless licenses should be treated as an indefinite-lived intangible asset. The Company will evaluate the useful life determination for its wireless licenses each year to determine whether events and circumstances continue to support their treatment as an indefinite useful life asset.

Evaluation of Indefinite-Lived Intangible Assets for Impairment

The Company determined that its unit of accounting should be based on geographic markets and deal markets. Unit of accounting of wireless licenses not associated with closed deals is based on geographic markets. Unit of accounting of wireless licenses associated with closed deals is based on the deal markets. The Company’s wireless licenses not associated with closed deals are tested for impairment based on the geographic markets, as the Company will be utilizing the existing wireless narrowband licenses, or broadband licenses if applicable, as part of facilitating broadband spectrum networks at a geographic market level. The Company’s wireless licenses associated with closed deals are tested for impairment based at the deal market level. The Company may elect to first perform a qualitative assessment to determine whether it is more likely than not that the fair value of an intangible asset is less than its carrying value. If the Company does not perform the qualitative assessment, or if the qualitative assessment indicates it is more likely than not that the fair value of the intangible asset is less than its carrying amount, the Company will calculate the estimated fair value of the intangible asset. If the estimated fair value of the spectrum licenses is lower than their carrying amount, an impairment loss is recognized. The Company will use a market-based approach to estimate fair value for impairment testing purposes except for deals that were realized as of the valuation date, for which a transaction specific market approach will be used.

The valuation approach used to estimate fair value for the purpose of impairment testing requires management to use complex assumptions and estimates such as population, discount rates, industry and market considerations, long-term market equity risk, as well as other factors. These assumptions and estimates depend on the Company’s ability to accurately predict forward looking assumptions including successfully applying for broadband licenses, commercializing the Company’s 900 MHz Broadband Spectrum and properly estimating favorable deal terms over the life of the contract. For impairment testing, estimated fair value is determined using a market-based approach primarily using the 600 MHz auction price. The FCC will use

Page F- 9

the spectrum price based on the average price paid in the FCC’s 600 MHz auction to calculate the Anti-Windfall Payments, a payment to the U.S. Treasury from a 900 MHz broadband applicant, if the applicant relinquishes less than 6 MHz (or 240 channels) of spectrum for any full or fractional MHz less than 6 MHz. The estimated fair value of realized deals is determined using a transaction specific market approach based on the deal specific terms and adjusted for the Company’s required rate of return and present value taking into consideration the timing of payments.

During the years ended March 31, 2024 and 2023, the Company performed a step one quantitative approach impairment test as of January 1, 2024 and January 1, 2023, respectively, to determine if the fair value of the combined licenses by the associated geographical or deal market exceeds the carrying value for each geographical or deal market. During March 31, 2023 (“Fiscal 2023”), the Company shifted from a probability analysis approach to a more detailed approach with measurable qualitative metrics. The new approach, Demonstrated Intent (“DI”), determines how likely a deal is to close based on certain qualitative factors, like applying for an experimental license, entering into a request for proposal, joining certain utility board or publicly backing 900 MHz Broadband Spectrum and its application. As a result, the Company will continue to utilize the DI scores on a go-forward basis for the Company’s impairment analysis. Based on the results of the impairment test, there were no impairment charges recorded during the year ended March 31, 2024 and 2023.

Exchanges of Intangible Assets

At times, the Company enters into agreements to exchange or cancel spectrum licenses. Upon entering into the arrangement, if the transaction has been deemed to have commercial substance, spectrum licenses are reviewed for impairment. The licenses are exchanged or cancelled at their carrying value and adjusted for any gain or loss recognized. Upon receipt of FCC approval, the spectrum licenses acquired as part of an exchange of nonmonetary assets are recorded at their fair value as of the exchange date. The difference between the fair value of the spectrum licenses obtained, carrying value of the spectrum licenses transferred and cash paid, if any, is recognized as a gain or loss on disposal of spectrum licenses reported separately on the Company’s Consolidated Statements of Operations. For the purpose of the valuation of broadband licenses received in connection with nonmonetary exchanges, the Company utilizes the 600 MHz Auction price per MHzPop, which represents level two of the fair value hierarchy. If the transaction lacks commercial substance or the fair value of the acquired asset cannot be determined, the acquired spectrum licenses are recorded at the carrying value of the spectrum assets transferred, cancelled or exchanged.

See Note 6 Intangible Assets for a discussion on the Company’s spectrum exchanges during the years ended March 31, 2024 and 2023.

Spectrum Receivable Costs and Deferred Broadband Costs

Spectrum receivable costs represent prepayments made to acquire, retune or swap narrowband wireless licenses for cash consideration. The initial deposits to incumbents are recorded as spectrum receivable costs on the Company’s Consolidated Balance Sheets and are refundable if the FCC does not approve the sale, retuning or swap of the spectrum. Upon closing the associated deal, the costs are transferred to intangible assets on the Company’s Consolidated Balance Sheets for purchases of licenses and to deferred broadband costs on the Company’s Consolidated Balance Sheets for deals related to swap or retuning of narrowband licenses. In fiscal year 2024, the total cost transferred from spectrum receivable costs to intangible assets and deferred broadband costs amounted to $9.1 million and $10.9 million, respectively. The Company will review the assets on a periodic basis to determine if an impairment exists. If it is determined that there is an impairment, the Company will expense the assets to the extent of the potential loss. Upon exchanging the Company’s narrowband licenses for broadband licenses, the Company will transfer the deferred broadband costs to intangible assets.

Long-Lived Assets and Right of Use Assets Impairment

The Company evaluates long-lived assets and right of use assets, other than intangible assets with indefinite lives, for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset group may not be recoverable. Asset groups are determined at the lowest level for which identifiable cash flows are largely independent of cash flows of other groups of assets and liabilities. When the carrying amount of the asset groups are not recoverable and exceeds its fair value, an impairment loss is recognized equal to the excess of the asset group’s carrying value over the estimated fair value. There were no impairment charges during the years ended March 31, 2024 and 2023.

Fair Value Measurement

A Level 1, Level 2 or Level 3 fair value hierarchy is used to categorize fair value amounts depending on the quality of inputs used to measure the fair value. Level 1 fair value derived inputs utilize quoted prices in active markets for identical assets or liabilities. Level 2 fair value derived inputs are based on quoted prices for similar assets and liabilities in active markets or

Page F- 10

based on inputs other than quoted prices for the assets or liability that are either directly or indirectly observable. Level 3 fair value derived inputs are unobservable for the asset or liability as a result of little, if any, market activity for the asset or liability.

The Company uses appropriate valuation techniques for the fair values of the applicable assets or liabilities based on the available inputs. When available, the Company measures fair value using Level 1 inputs as they generally provide the most reliable evidence of fair value. The inputs may fall into different levels within the hierarchy in some valuations. In these cases, the fair value hierarchy of the asset or liability level is based on the lowest level of input that is significant to the fair value measurements.

Financial Instruments

The carrying values of the Company’s financial instruments, including cash and cash equivalents, accounts receivable, escrow deposit, accounts payable, accrued expenses and contingent liability approximate their fair values.

Leases 

Leases in which the Company is the lessee are comprised of corporate office space and tower space. Substantially all of the leases are classified as operating leases. The Company is obligated under certain lease agreements for office space with lease terms expiring on various dates from October 31, 2024 through January 31, 2029, which includes lease extensions ranging from three to ten-years for its corporate headquarters. The Company entered into multiple lease agreements for tower space related to its spectrum holdings. The lease expiration dates range from April 30, 2024 to March 21, 2031.

In accordance with Financial Accounting Standards Board, (“FASB”) Accounting Standards Codification, Leases (“ASC 842”), the Company recognized right of use (“ROU”) assets and corresponding lease liabilities on the Company’s Consolidated Balance Sheets for its operating lease agreements with contractual terms greater than 12 months. Lease liabilities are based on the present value of remaining lease payments over the lease term. As the discount rate implied in the Company’s leases is not readily determinable, the present value is calculated using the Company’s incremental borrowing rate, which is estimated to approximate the interest rate on a collateralized basis with similar terms.

Revenue Recognition

Revenues are recognized when a contract with a customer exists and control of the promised goods or services is transferred to the Company’s customers, in an amount that reflects the consideration it expects to be entitled to in exchange for those goods or services.

A performance obligation is a promise in a contract to transfer a distinct good or service to the customer and is the unit of account in Accounting Standards Codification, Revenue from Contracts with Customers (“ASC 606”). A contract’s transaction price is allocated to each distinct performance obligation and is recognized as revenue when, or as, the performance obligation is satisfied, which typically occurs when the services are rendered. Determining whether products and services are considered distinct performance obligations that should be accounted for separately versus together may require significant judgment. The Company’s contracts with customers may include multiple performance obligations. For such arrangements, the Company allocates revenue to each performance obligation based on its relative standalone selling price. It generally determines standalone selling prices based on the prices charged to customers under contracts involving only the relevant performance obligation. Judgment may be used to determine the standalone selling prices for items that are not sold separately, including services provided at no additional charge. For the Company’s customer agreements, most of the performance obligations involve delivering leased spectrum on a county-by-county basis and are generally satisfied over time as services are provided. The nature of the licenses provide the benefit of the leased spectrum regardless of whether the customer uses the spectrum or not. As a result, revenue will be recognized ratably as the Company delivers cleared 900 MHz Broadband Spectrum and the associated broadband leases to the customer on a county-by-county basis over the contractual term.

Since a contract has payment terms that differ from the timing of revenue recognition, the Company will assess whether the transaction price for those contracts include a significant financing component. The Company expects that the period between the transfer of a promised good or service to a customer and the customer payment for that good or service will not constitute a significant financing component. Most of the Company’s spectrum agreements have milestone payments, which align the payment schedule with the clearing and delivery of broadband spectrum. The Company may be entitled to receive an initial deposit, which is not considered a significant financing component because it is used to obtain exclusive rights to the spectrum upon clearing and delivery. As a result, the prepayment structure does not result in a financing component as it mitigates the risk for both parties and secures the exclusive use of the Company’s 900 MHz Broadband Spectrum.

The Company recognizes an asset for the incremental costs of obtaining a contract with a customer if it expects the benefit of those costs to be longer than one year. The Company determined that certain sales commissions met the requirements to be capitalized and were recorded as an asset upon the Company’s adoption of ASC 606. For the years ended March 31, 2024 and 2023, the Company capitalized commission costs required to obtain long-term 900 MHz Broadband Spectrum lease agreements which will be amortized over the contractual term.

Page F- 11

Contract Assets and Liabilities

The Company records a contract asset when the Company has satisfied a performance obligation but does not yet have an unconditional right to consideration. Contract assets are included in prepaid expenses and other current assets in the consolidated balance sheets. The Company will review the contract asset on a periodic basis to determine if an impairment exists as a result of a potential credit loss exposure. If it is determined that there is an impairment, the Company will expense the contract asset to the extent of the potential credit loss.

Contract liabilities primarily relate to advance consideration received from customers for spectrum services, for which the control of these services has not been transferred to the customer. These contract liabilities are recorded as deferred revenue on the balance sheet.

Product Development Costs

The Company charges all product and development costs to expense as incurred. Types of expense incurred in product and development costs include employee compensation, consulting, travel, equipment and technology costs.

Advertising and Promotional Expense

The Company expenses advertising and promotional costs as incurred. Advertising and promotional expense was approximately $62,000 and $92,000 for the years ended March 31, 2024 and 2023, respectively.

Stock Compensation

The Company accounts for stock options in accordance with U.S. GAAP, which requires the measurement and recognition of compensation expense, based on the estimated fair value of awards granted to consultants, employees and directors. The Company estimates the fair value of share-based awards on the date of grant using an option-valuation model. The value of the portion of the award that is ultimately expected to vest is recognized as expense in the Company’s statements of operations over the requisite service periods. In the event the participant’s employment by or engagement with (as a director or otherwise) the Company terminates before exercise of the options granted, the stock options granted to the participant shall immediately expire and all rights to purchase shares thereunder shall immediately cease and expire and be of no further force or effect, other than applicable exercise rights for vested shares that may extend past the termination date as provided for in the participant’s applicable option award agreement. Additionally, the Company’s Compensation Committee (the “Compensation Committee”) adopted an Executive Severance Plan (the “Severance Plan”) in February 2015, which was amended in February 2019, and the Company subsequently entered into Severance Plan Participation Agreements with its executive officers. In addition to providing participants with severance payments, the Severance Plan provides for accelerated vesting and extends the exercise period for outstanding equity awards if the Company terminates a participant’s service for reasons other than cause, death or disability or the participant terminates his or her service for good reason, whether before or after a change of control (each of such terms as defined in the Severance Plan). In addition to the Severance Plan, the equity awards issued to the Company’s President and Chief Executive Officer provide for accelerated vesting upon termination of service for reasons other than cause or a resignation for good reason; involuntary termination in connection with a change in control; or a change in control with a purchase price at or above $100 per share (each of such terms defined in the equity award agreements).

To calculate option-based compensation, the Company uses the Black-Scholes option valuation model. The compensation cost for the stock options with a graded vesting schedule is recognized using an accelerated method over the explicit vesting period. Stock options have a maximum term of ten years from the date they are granted, and vest over a requisite service period of three years, or four years for grants prior to November 2020, subject to acceleration in certain circumstances. The Company’s determination of fair value of option-based awards on the date of grant using the Black-Scholes model is affected by assumptions regarding a number of subjective variables. These variables include the expected volatility of the Company’s stock price, which is based on the weighted-average historical volatility of its stock, expected term, which is based on option history with adjustments for vesting schedule and contractual terms, risk-free interest rate, which is based on the treasury zero-coupon yield appropriate for the term of the option-based award as of the grant date; and expected dividends as applicable, which is zero, as the Company has never paid any cash dividends. Any future determination to pay dividends will be at the discretion of the Board and will depend on the Company’s financial condition, results of operations, capital requirements, restrictions contained in any financing instruments and such other factors as the Board deems relevant in its sole discretion. Therefore, the Company uses an expected dividend yield of zero in the option-pricing model.

The fair value of restricted stock, restricted stock units and performance units without market conditions are measured based upon the quoted closing market price for the stock on the date of grant. The compensation cost for the restricted stock and restricted stock units is recognized on a straight-line basis over the explicit vesting period. Restricted stock granted to the Company employees vest over a requisite services period of four years, subject to acceleration in certain circumstances. Vested restricted stock units are settled and issuable upon the earlier of the date the employee ceases to be an employee of the

Page F- 12

Company or a date certain in the future. The compensation cost for the performance units without market conditions is recognized ratably over the service period if it is probable that the performance condition will be met.

The Company uses a Monte Carlo simulation model to determine the fair value of performance units with market condition at grant date. The Monte Carlo simulation model is based on a discounted cash flow approach, with the simulation of a large number of possible stock price outcomes for the Company’s stock and the target composite index. The use of the Monte Carlo simulation model requires the input of a number of assumptions including expected volatility of the Company’s stock price, which is based on the weighted-average historical volatility of its stock; correlation between changes in the Company’s stock price and changes in the target composite index, which is based on the historical relationship between the Company’s stock price and the target composite index average; risk-free interest rate, which is based on the treasury zero-coupon yield appropriate for the term of the performance unit as of the grant date; and expected dividends as applicable, which is zero, as the Company has never paid any cash dividends. Any future determination to pay dividends will be at the discretion of the Board and will depend on the Company’s financial condition, results of operations, capital requirements, restrictions contained in any financing instruments and such other factors as the Board deems relevant in its sole discretion. Therefore, the Company has used an expected dividend yield of zero in the Monte Carlo simulation model. The compensation cost for the performance units with market condition is recognized ratably over the service period.

No tax benefits have been attributed to the share-based compensation expense because the Company maintains a full valuation allowance for all net deferred tax assets.

All excess tax benefits and tax deficiencies, including tax benefits of dividends on share-based payment awards, are recognized as income tax expense or benefit in the income statement, eliminating the notion of the additional paid-in capital (“APIC”) pool. The excess tax benefits are classified as operating activities along with other income tax cash flows rather than financing activities in the statement of cash flows. The tax effects of exercised or vested awards are treated as discrete items in the reporting period in which they occur. Cash payments to tax authorities in connection with shares withheld to meet statutory tax withholding requirements are presented as a financing activity in the statement of cash flows.

Retirement of common stock

From time to time, the Company may acquire its common stock through share repurchases or option exercise swaps and return these shares to authorized and unissued. If the Company elects to retire these shares, the Company’s policy is to allocate a portion of the repurchase price to par value of common stock with the excess over par value allocated to accumulated deficit.

Income Taxes 

The Company utilizes the asset and liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the carrying amounts and the tax bases of assets and liabilities as well as from net operating loss and tax credit carryforwards. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in operations in the period that includes the enactment date. A valuation allowance is established when it is estimated that it is more likely than not that the tax benefit of a deferred tax asset will not be realized.

Changes in valuation allowance for the years ended March 31, 2024 and 2023 are summarized below (in thousands):

	2024		2023
Balance at beginning of the year	$	85,984	$	79,998
Charged to costs and expenses	842		1,218
Changes in net loss carryforward and other	2,916		4,768
Balance at end of the year	$	89,742	$	85,984

Accounting for Uncertainty in Income Taxes

The Company recognizes the effect of tax positions only when they are more likely than not to be sustained. Management has determined that the Company had no uncertain tax positions that would require financial statement recognition or disclosure. The Company is no longer subject to U.S. federal, state or local income tax examinations for periods prior to 2019. When applicable, the Company recognizes interest and penalties related to unrecognized tax benefits as a component of income tax expense.

Net Loss Per Share of Common Stock

Basic net loss per common share is calculated by dividing the net loss attributable to common stockholders by the weighted-average number of common shares outstanding during the period, without consideration for potentially dilutive securities. For purposes of the diluted net loss per share calculation, preferred stock, convertible notes payable-affiliated

Page F- 13

entities, stock options, restricted stock and warrants are considered to be potentially dilutive securities. Diluted earnings per share is computed using the treasury stock method. Because the Company has reported a net loss for the years ended March 31, 2024 and 2023 diluted net loss per common share is the same as basic net loss per common share for those periods.

Common stock equivalents resulting from potentially dilutive securities approximated 241,629 and 352,216 and at March 31, 2024 and 2023 respectively, and have not been included in the dilutive weighted average shares of common stock outstanding, as their effects are anti-dilutive.

Recently Issued Accounting Pronouncements

In October 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Updates (“ASU”) 2023-06, Disclosure Improvements: Codification Amendment in Response to the SEC’s Disclosure Update and Simplification Initiative.

Page F- 14

Illinois, covering approximately 7.5 million people. Each Ameren Agreement is for an initial term of 30 years with a 10-year renewal option for an additional payment. The scheduled prepayments for the 30-year initial terms of the Ameren Agreements total $47.7 million, of which $0.3 million was received by the Company in February 2021, $5.4 million in September 2021 and $17.2 million in October 2021. The prepayments received to date encompass the initial upfront payment(s) due upon signing of the Ameren Agreements and payments for delivery of the relevant 1.4 x 1.4 MHz cleared spectrum in several metropolitan counties throughout Missouri and Illinois, in accordance with the terms of the Ameren Agreements. The remaining prepayments for the 30-year initial term are due by mid-2026, per the terms of the Ameren Agreements and as the Company delivers the relevant cleared 900 MHz Broadband Spectrum and the associated broadband leases. The Company is working with the remaining incumbents to clear the 900 MHz Broadband Spectrum allocation in Ameren’s service territory. In August 2021, the FCC granted the first 900 MHz broadband leases to the Company for several counties in Ameren’s service territory, for which the Ameren Agreements were also subsequently approved by the FCC. In accordance with ASC 606, the payments of prepaid fees under the Ameren Agreements will be accounted for as deferred revenue on the Company’s Consolidated Balance Sheets. Revenue is recognized over time as the performance obligations of clearing the 900 MHz Broadband Spectrum and the associated broadband leases are delivered by respective county, over the contractual term of 30-years.

In September 2021, the Company entered into a long-term lease agreement of 900 MHz Broadband Spectrum with Evergy. The Evergy service territories covered by the Evergy Agreement are in Kansas and Missouri, with a population of approximately 3.9 million people. The Evergy Agreement is for an initial term of 20 years with two 10-year renewal options for additional payments. Prepayment in full of the $30.2 million for the 20-year initial term, which was due and payable within thirty (30) days after execution of the Evergy Agreement, was received by the Company in October 2021. During the year ended March 31, 2024, the Company cleared the 900 MHz Broadband Spectrum allocation covered by the Evergy Agreement. In accordance with ASC 606, the payments of prepaid fees under the Evergy Agreement will be accounted for as deferred revenue on the Company’s Consolidated Balance Sheets. Revenue is recognized over time as the performance obligations of clearing the 900 MHz Broadband Spectrum and the associated broadband leases are delivered by respective county, over the contractual term of 20-years.

In October 2022, the Company entered into an agreement with Xcel Energy providing Xcel Energy dedicated long-term usage of the Company’s 900 MHz Broadband Spectrum for a term of 20 years throughout Xcel Energy’s service territory in eight states including Colorado, Michigan, Minnesota, New Mexico, North Dakota, South Dakota, Texas and Wisconsin. The Xcel Energy Agreement also provides Xcel Energy an option to extend the agreement for two 10-year terms for additional payments. The Xcel Energy Agreement allows Xcel Energy to deploy a PLTE network to support its grid modernization initiatives for the benefit of its approximately 3.7 million electricity customers and 2.1 million natural gas customers. The scheduled prepayments for the 20-year initial term of the Xcel Energy Agreement total $80.0 million, of which $8.0 million was received by the Company in December 2022. In July 2023 and November 2023, the Company delivered the cleared 900 MHz Broadband Spectrum and the associated broadband leases and received milestone payments of $21.2 million in each period. During the year ended March 31, 2024, the Company delivered the cleared 900 MHz Broadband Spectrum and the associated broadband leases and received a milestone payment of $16.8 million in January 2024. The remaining prepayments for the 20-year initial term are due by mid-2028, per the terms of the Xcel Energy Agreement and as the Company delivers the relevant cleared 900 MHz Broadband Spectrum and the associated broadband leases. The Company is working with the remaining incumbents to clear the 900 MHz Broadband Spectrum allocation in Xcel Energy service territories. In accordance with ASC 606, the payments of prepaid fees under the Xcel Energy Agreement will be accounted for as deferred revenue on the Company’s Consolidated Balance Sheets. Revenue will be recognized over time as the performance obligations of clearing the 900 MHz Broadband Spectrum and the associated broadband leases are delivered by respective county, over the contractual term of approximately 20-years.

In November 2023, the Company entered into an agreement with TECO to provide TECO the use of the Company’s 900 MHz Broadband Spectrum for a term of 20 years throughout TECO’s service territory in West Central Florida the TECO Agreement. The TECO Agreement also provides TECO an option to extend the agreement for two 10-year terms for additional payments. The TECO Agreement, which covers an approximately 2,000-square-mile service territory in West Central Florida, is expected to enable TECO to deploy a PLTE network. The scheduled prepayments for the 20-year initial terms of the TECO Agreement total $34.5 million, of which $6.9 million was received by the Company in December 2023. The remaining prepayments for the 20-year initial term are due by fiscal year 2026, per the terms of the TECO Agreement and as the Company delivers the relevant cleared 900 MHz Broadband Spectrum and the associated broadband leases. The Company is working with incumbents to clear the 900 MHz Broadband Spectrum allocation in TECO service territories. The payments of prepaid fees under the TECO Agreement will be accounted for as deferred revenue on the Company’s Consolidated Balance Sheets. Revenue will be recognized over time as the performance obligations of clearing the 900 MHz Broadband Spectrum and the associated broadband leases are delivered by respective county, over the contractual term of approximately 20 years.

9. Leases 

All the leases in which the Company is the lessee are comprised of corporate office space and tower space. The Company is obligated under certain lease agreements for office space with lease terms expiring on various dates from October 31, 2024 through January 31, 2029, which includes lease extensions for its corporate headquarters ranging from three to ten-years. The Company entered into multiple lease agreements for tower space. The lease expiration dates range from April 30, 2024 to March 21, 2031.

Substantially all of the Company’s leases are classified as operating leases. Operating lease agreements are required to be recognized on the Company’s Consolidated Balance Sheets as right of use (“ROU”) assets and corresponding lease liabilities.

Page F- 18

ROU assets include any prepaid lease payments and exclude any lease incentives and initial direct costs incurred. Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term. The lease terms may include options to extend or terminate the lease if it is reasonably certain that the Company will exercise that option.

Weighted-average remaining lease term and incremental borrowing rate for the Company’s operating leases are as follows:

	2024		2023
Weighted average term - operating lease liabilities	3.59 years		2.87 years
Weighted average incremental borrowing rate - operating lease liabilities	9	%	12	%

Total lease cost amounted to approximately $1.9 million and $1.8 million, respectively, for the years ended March 31, 2024 and 2023. Total lease cost is included in general and administrative expenses on the Company’s Consolidated Statements of Operations.

10. Income Taxes

For the year ended March 31, 2024, the Company had federal and state NOL carryforwards of approximately $307.3 million and $212.0 million respectively. Of these federal and state NOLs, approximately $66.2 million and $169.1 million, respectively, are expiring in various amounts from 2024 through 2037. The remaining federal and state NOLs of approximately $241.1 million and $42.9 million, respectively, have an indefinite life but the federal NOLs may only offset 80% of taxable income when used. For the year ended March 31, 2023, the Company incurred federal and state operating losses of approximately $327.8 million and $216.7 million, respectively, to offset future taxable income, of which $237.5 million federal NOL and $63.7 million of state NOLs can be carried forward indefinitely but can only offset 80% of taxable income when used.

Page F- 19

The Company has net deferred tax assets, before applying the valuation allowance, of approximately $83.5 million and $80.5 million relating principally to the NOLs as of March 31, 2024 and 2023, respectively. Federal NOL carryforwards may be subject to limitations as a result of the change in ownership that occurred in the year ended March 31, 2015, as defined under Internal Revenue Code Section 382. State NOL carryforwards are subject to limitations which differ from federal law in that they may not allow the carryback of net operating losses and have shorter carryforward periods.

Accounting Standards Codification Topic 740, Income Taxes, requires that a valuation allowance be recorded to reduce deferred tax assets when it is more likely than not that the tax benefit of the deferred tax assets will not be realized. The evaluation includes the consideration of all available evidence, both positive and negative, regarding historical operating results including recent years with reported losses, the estimated timing of future reversals of existing taxable temporary differences, estimated future taxable income exclusive of reversing temporary differences and carryforwards, and potential tax planning strategies which may be employed to prevent an operating loss or tax credit carryforward from expiring unused. In situations where a three-year cumulative loss condition exists, accounting standards limit the ability to consider projections of future results as positive evidence to assess the realizability of deferred tax assets. Since inception, the Company has mainly incurred tax losses which represents significant negative evidence toward the realizability of its deferred tax assets. Therefore, the Company continues to apply a full valuation allowance against its deferred tax assets as of March 31, 2024 and 2023, with the exception of the net deferred tax liability of approximately $6.3 million and $5.4 million, respectively, regarding indefinite-lived intangibles.

For Fiscal 2024, analysis of the state NOL carryforwards revealed that most of them are not indefinite. The Company recorded $0.4 million of state deferred tax expense during the year March 31, 2024 and increased the state deferred tax liability by the same amount from the inability to use the state NOL carryforwards against the indefinite-lived intangible. For Fiscal 2023, the Company recorded $0.8 million of state deferred tax benefit during the year March 31, 2023 and decreased the state deferred tax liability by the same amount from the inability to use the state NOL carryforwards against the indefinite-lived intangible. This valuation allowance has no effect on the Company’s ability to utilize the deferred tax assets to offset future taxable income, if generated. As required by U.S. GAAP, the Company will continue to assess the likelihood that the deferred tax assets will be realizable in the future and the valuation allowance will be adjusted accordingly. The tax benefits relating to any reversal of the valuation allowance on the net deferred tax assets in a future period will be recognized as a reduction of future income tax expense in that period.

Net deferred tax assets and liabilities consist of the following as of March 31, 2024 and 2023 (in thousands):

13. Contingencies and Guaranty

Contingent Liabilities 

In February 2021, the Company entered into an agreement with SDG&E to sell 900 MHz Broadband Spectrum throughout SDG&E’s California service territory, including San Diego and Imperial Counties and portions of Orange County (the “SDG&E Agreement”), for a total payment of $50.0 million. The SDG&E Agreement will support SDG&E’s deployment of a PLTE network for its California service territory, with a population of approximately 3.6 million people. Delivery of the relevant 900 MHz Broadband Spectrum and the associated broadband licenses by county to SDG&E commenced in Fiscal 2023 and is scheduled for completion before the end of fiscal year 2024. The total payment of $50.0 million is comprised of an initial payment of $20.0 million, received in February 2021 and the remaining payments which are due as the Company delivers the relevant cleared 900 MHz Broadband Spectrum and the associated broadband licenses to SDG&E. As the Company is required to refund payments it has received from SDG&E in the event of termination or non-delivery of the specific county’s full 900 MHz Broadband Spectrum, it recorded the payments as contingent liability on the Company’s Consolidated Balance Sheets. A reduction in the contingent liability and a gain or loss on the sale of spectrum will be recognized for each county once the Company delivers the full cleared 900 MHz Broadband Spectrum and the associated broadband license(s) to SDG&E.

In September 2022, the Company transferred to SDG&E 1.4 x 1.4 MHz cleared 900 MHz Broadband Spectrum and the associated broadband license related to Imperial County and received a milestone payment of $0.2 million. In September 2023, the Company transferred to SDG&E the San Diego County broadband license and received a milestone payment of $25.2 million net of delivery delay adjustments of $1.1 million. In December 2023, the Company transferred to SDG&E the remainder of the cleared 900 MHz Broadband Spectrum and the associated broadband license related to Imperial County and received a milestone payment of $0.2 million. This resulted in the recognition of a gain on the sale of spectrum and derecognition of the contingent liability associated with San Diego County and Imperial County of $19.2 million. See Note 6 Intangible Assets for further discussion on the sale of intangible assets.

Subsequent to the derecognition of the contingent liability related to the delivery of San Diego County and Imperial County licenses, the remaining contingent liability related to SDG&E of $1.0 million for Orange County was classified as a short-term liability due to the expected timing of delivery.

LCRA Refund Obligation

In April 2023, the Company entered into the LCRA Agreement for a total payment of $30.0 million, to be paid through fiscal year 2026 pursuant to the terms of the agreement. During the quarter ended December 31, 2023, the Company received $15.0 million in milestone payments, of which $7.5 million was deposited in an escrow account. The remaining payments are due as the Company delivers the relevant cleared 900 MHz Broadband Spectrum and the associated broadband licenses to LCRA. As the Company is required to refund the deposit it has received from LCRA in the event of termination or non-delivery of the specific county’s full cleared 900 MHz Broadband Spectrum, it recorded the payments as contingent liability on the Company’s Consolidated Balance Sheets. A reduction in the contingent liability and a gain or loss on the sale of spectrum will be recognized for each county once the Company delivers the full cleared 900 MHz Broadband Spectrum and the associated broadband license(s) to LCRA. See Note 5 Escrow Deposits for further discussion on the escrow deposit.

Xcel Energy Guaranty

In October 2022, the Company entered into an agreement with Xcel Energy providing Xcel Energy dedicated long-term usage of the Company’s 900 MHz Broadband Spectrum for a term of 20 years throughout Xcel Energy’s service territory in eight states the Xcel Energy Agreement. In connection with Xcel Energy Agreement, the Company entered into a guaranty agreement, under which the Company guaranteed the delivery of the relevant 900 MHz Broadband Spectrum and the associated broadband licenses in Xcel Energy’s service territory in eight states along with other commercial obligations. In the event of default or non-delivery of the specific territory’s 900 MHz Broadband Spectrum, the Company is required to refund payments it has received. In addition, to the extent Anterix has performed any obligations, the Company’s liability and remaining obligations under the Xcel Energy Agreement will extend only to the remaining unperformed obligations. The Company recorded $67.1 million in deferred revenue in connection with the prepayments received as of March 31, 2024. The Company commenced delivery of the relevant cleared 900 MHz Broadband Spectrum and the associated broadband leases in the first quarter of fiscal year 2024 and will continue through 2029. As of March 31, 2024, the maximum potential liability of future undiscounted payments under this agreement is approximately $65.2 million.

Litigation

In addition to commitments and obligations in the ordinary course of business as reflected in the lease footnote above, the Company may be subject, from time to time, to various claims and pending and potential legal actions arising out of the normal conduct of its business. The Company assesses contingencies to determine the degree of probability and range of possible loss for potential accrual in its financial statements. Because litigation is inherently unpredictable and unfavorable resolutions could occur, assessing litigation contingencies is highly subjective and requires judgments about future events. When evaluating contingencies, the Company may be unable to provide a meaningful estimate due to a number of factors, including the procedural status of the matter in question, the presence of complex or novel legal theories and/or the ongoing discovery and development of information important to the matters. In addition, damage amounts claimed in litigation against it may be unsupported, exaggerated or unrelated to possible outcomes, and as such are not meaningful indicators of its potential liability.

The Company regularly reviews contingencies to determine the adequacy of its accruals and related disclosures. During the period presented, the Company has not recorded any accrual for loss contingencies associated with any claims or legal proceedings; determined that an unfavorable outcome is probable or reasonably possible; or determined that the amount or range of any possible loss is reasonably estimable. However, the outcome of legal proceedings and claims brought against the Company is subject to significant uncertainty. Therefore, although management considers the likelihood of a material adverse outcome to be remote, if one or more of these legal matters were resolved against the Company in a reporting period, the Company’s consolidated financial statements for that reporting period could be materially adversely affected.

Pandemic and Macroeconomic Conditions

Recent macroeconomic events, inflation, and geopolitical matters, have increased operating costs or resulted in delays in customer contracting or impacted the availability of equipment necessary for the deployment of the Company’s target customers’ planned PLTE projects. The Company continues to closely monitor these risks. Although difficult to quantify, the Company believes the current macroeconomic environment, including inflation, may have an adverse effect on the Company’s target customers’ businesses, which may harm the Company’s commercialization efforts and negatively impact the Company’s revenues and liquidity. If the Company is not able to control its operating costs or if the Company’s commercialization efforts are slowed or negatively impacted, continued periods of high inflation could have a material adverse effect on the Company’s business, operating results and financial condition.

14. Subsequent Events 

Oncor Agreement

On June 26, 2024, the Company entered into a license purchase agreement with Oncor Electric Delivery Company LLC (“Oncor”) for total estimated consideration of $102.5 million under which Oncor will purchase 900 MHz spectrum licenses covering 95 counties to deploy a private wireless broadband network in its transmission and distribution service area (the “Oncor Agreement”). The timing and rights to milestone payments could vary as 900 MHz broadband licenses are granted by the FCC, broadband licenses are assigned to Oncor, and incumbents are cleared by the Company. Oncor operates more than 143,000 circuit miles of transmission and distribution lines in Texas, delivering electricity to more than four million homes and businesses across a service territory that has an estimated population of approximately 13 million people.
