Summary of Significant Accounting Policies (Policies)	12 Months Ended
Summary of Significant Accounting Policies (Policies)	Mar. 31, 2022
Accounting Policies [Abstract]
Basis of Presentation and Use of Estimates	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.
Correction of Immaterial Error and Reclassification	Correction of Immaterial ErrorIn connection with preparing its financial statements for the quarter ended December 31, 2021, the Company determined that it incorrectly accounted for idled assets as Held For Future Use within its Annual Report on Form 10-K for the year ended March 31, 2021, which resulted in an incorrect presentation of the asset classification included in the Property and Equipment footnote within the Notes to the Consolidated Financial Statements. The idled assets should have remained as in-service assets with no change in classification as the idling of these assets is temporary in nature. Reclassifications Certain amounts previously reported in the Company’s Consolidated Statement of Operations for prior years have been reclassified to conform to the presentation within this Annual Report on Form 10-K. The reclassification includes the consolidation of the restructuring costs line into the general and administrative line within the Company’s Consolidated Statement of Operations.
Cash and Cash Equivalents	Cash and Cash Equivalents 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.
Concentrations of Credit Risk	Concentrations of Credit Risk Financial instruments which potentially expose the Company to concentrations of credit risk consist primarily of cash and cash equivalents. The cash balance at times may exceed federally insured limits, however, the Company places its cash and temporary cash investments with financial institutions for which credit loss is not anticipated.
Allowance for Doubtful Accounts	Allowance for Doubtful Accounts An allowance for uncollectible receivables is estimated, as required, based on a combination of write-off history, aging analysis and any specific known troubled accounts. The Company reviews its allowance for uncollectible receivables on a quarterly basis. Past due balances meeting specific criteria are reviewed individually for collectability.
Property and Equipment	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	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 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 in the Consolidated Statement of Operations.
Intangible Assets	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 Historically, wireless licenses were tested for impairment on an aggregate basis, consistent with the Company’s dispatch business at a national level. Effective Fiscal 2021, the Company determined that its unit of accounting should be based on geographic markets and that it should test its wireless licenses for impairment based on the individual markets, as the Company will be utilizing the wireless licenses as part of facilitating broadband spectrum networks at an individual 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. 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 are forward-looking and depend on the Company’s ability to successfully apply for broadband licenses and commercialize its 900 MHz Broadband Spectrum. During Fiscal 2022, the Company changed the date of its annual impairment assessment from March 31, its fiscal year-end, to January 1. For the year ended March 31, 2022, the Company performed a step zero qualitative approach impairment test as of January 1, 2022, for each geographical market to test indefinite-lived intangible assets for impairment by first assessing qualitative factors to determine whether it is more-likely-than-not that the fair value of an indefinite-lived intangible asset is impaired as a basis for determining whether it is necessary to perform quantitative impairment testing. As a result of the step zero test, the Company was not required to perform a step one analysis. As of and for the year ended March 31, 2021, the Company performed a step one quantitative impairment test to determine if the fair value of the licenses exceed the carrying values for each geographical market. Estimated fair value is determined using a market-based approach primarily using the 600 MHz auction price as the Report and Order noted that the FCC will use as a reference the spectrum price based on the average price paid in the FCC’s 600 MHz auction to calculate the Anti-Windfall Payments. For the year ended March 31, 2020, the Company performed a step zero qualitative approach impairment test on an aggregate basis to test indefinite-lived intangible assets for impairment by first assessing qualitative factors to determine whether it is more-likely-than-not that the fair value of an indefinite-lived intangible asset is impaired as a basis for determining whether it is necessary to perform quantitative impairment testing. Based on the results of the impairment tests, there were no impairment charges recorded during the years ended March 31, 2022, 2021 and 2020. 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 new accounting basis, for those acquired from the FCC, or fair value for those acquired from third party, (collectively, the “acquired basis”). The difference between the acquired basis 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 in the Company’s Consolidated Statements of Operations. The acquired basis of spectrum licenses is based on information for which there is little or no observable market data. If the transaction lacks commercial substance or the acquired basis is not measurable, the acquired spectrum licenses are recorded at the carrying value of the spectrum assets transferred, cancelled or exchanged. 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, as defined in the Report and Order, which is considered the accounting basis for the new broadband licenses.
Long-Lived Asset and Right of Use Asset Impairment	Long-Lived Assets and Right of Use Assets Impairment The Company evaluates long-lived assets, including 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.
Equity Method Investment	Equity Method Investment The Company’s 19.5% investment in the TeamConnect LLC (the “LLC”) for which the Company is not the primary beneficiary and does not influence or control the activities that most significantly impact the LLC’s economic performance, are not consolidated and are accounted for under the equity method of accounting. Under the equity method of accounting, the LLC’s accounts are not reflected within the Company’s consolidated balance sheets and statements of operations. The Company’s share of the earnings of the LLC is reported as income (loss) on equity method investment in the Company’s consolidated statements of operations. The Company’s carrying value in an equity method investment is reported as equity method investment on the Company’s consolidated balance sheets. If the Company’s carrying value in an equity method is reduced to zero, no further losses are recorded in the Company’s consolidated financial statements unless the Company guarantees obligations of the LLC or commits additional funding. When the LLC subsequently reports income, the Company will not record its share of such income until it equals the amount of its share of losses not previously recognized.
Fair Value Measurement of Financial Instruments	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 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 Financial instruments, including cash and cash equivalents, accounts receivable, accounts payable and accrued expenses are carried at cost, which management believes approximates fair value because of the short-term maturity of these instruments.
Leases	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, 2023 through June 30, 2027, 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. 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 its 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	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 and the identified performance obligation has been satisfied. 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. Most of the Company’s performance obligations will be 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 licenses by county to the customer over the contractual term. 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. As a result of the customers being assigned to A BEEP and Goosetown (see Note 3 Revenue below), the Company’s capitalized sales commissions were impaired on April 1, 2019. For the years ended March 31, 2022 and 2021, the Company capitalized commission costs required to obtain long-term 900 MHz Broadband Spectrum lease agreements which will be amortized over the contractual term of approximately 30-years.
Direct Cost of Revenue	Direct Cost of Revenue The Company’s historical direct cost of revenue related to its TeamConnect service offering includes the costs of operating its dispatch network and its cloud-based solutions. With respect to sales of its historical software applications through its wireless carrier partners, direct cost of revenue includes the portion of service revenue retained by its domestic Tier 1 carrier or reseller partners pursuant to its agreements with these parties, which may include network services, connectivity, SMS service, sales, marketing, billing and other ancillary services.
Product Development Costs	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	Advertising and Promotional ExpenseThe Company expenses advertising and promotional costs as incurred.
Stock Compensation	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-pricing 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-pricing model. 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. 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 vesting period. The compensation cost for the performance units without market conditions is recognized when the performance criteria are expected to be complete. 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 of directors (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. 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	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.
Accounting for Uncertainty in Income Taxes	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	Net Loss Per Share of Common StockBasic 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 entities, stock options, restricted stock and warrants are considered to be potentially dilutive securities.
Recently Adopted Accounting Guidance and Recently Issued Accounting Pronouncements	Recently Adopted Accounting Guidance In June 2016, the FASB issued ASU 2016-13, Measurement of Credit Losses on Financial Instruments, and has subsequently modified several areas of the Accounting Standards Codification 326, Financial Instruments – Credit Losses, in order to provide additional clarity and improvements. The new standard requires entities to use a Current Expected Credit Loss impairment model based on expected losses rather than incurred losses. Under this model, an entity would recognize an impairment allowance equal to its current estimate of all contractual cash flows that the entity does not expect to collect from financial assets measured at amortized cost within the scope of the standard. The entity’s estimate would consider relevant information about past events, current conditions and reasonable and supportable forecasts, which will result in recognition of lifetime expected credit losses. As the Company was previously a smaller reporting company, the standard updates would have been effective beginning April 2023, however, due to the transition to a large accelerated filer during the current fiscal year, the updates were effective for the Company as of the fiscal year end 2022. The Company adopted the new standard effective March 31, 2022, and the adoption did not have a material impact on its consolidated financial statements and related disclosures. Recently Issued Accounting Pronouncements While there have been accounting standards that have been issued or proposed by the FASB or other standard-setting bodies that do not require adoption until a future date, these updates are not expected to have a material impact on the Company’s consolidated financial statements upon adoption.

Related Party Transactions	Mar. 31, 2022
Related Party Transactions [Abstract]
Related Party Transactions	Related Party Transactions Under the terms of the MOU, the Company was obligated to pay the LLC a monthly service fee for a 24-month period ending on January 7, 2021 for its assumption of the Company’s support obligations under the A BEEP and Goosetown Agreements.

As of March 31, 2021, there was no stock compensation expense recognized for the Stretch Goal described above under the performance-based restricted stock units as the 47,768 performance-based restricted stock units expired as unvested.

CEO Performance Units

Cumulative Spectrum Proceeds Monetized

On December 31, 2020, the Compensation Committee awarded performance-based restricted units to the Company’s President and Chief Executive Officer as part of the Succession Plan, (the “CEO Performance Units”). The performance-based restricted units will vest on a determination date of June 24, 2024 (“Determination Date”) (unless sooner triggered by an earlier involuntary termination), based on Cumulative Spectrum Proceeds Monetized (“CSPM”) metric over a four-year measurement period commencing on June 24, 2020, with 15,025 units vesting if the minimum CSPM level is achieved, 30,049 units vesting if the target CSPM metric is achieved and up to 60,098 vesting if the maximum CSPM metric is achieved.

The Company recorded approximately $0.3 million and $0.1 million of stock compensation expense included in general and administrative expenses reported in the Consolidated Statements of Operations relating to the CEO Performance Units - CSPM for the years ended March 31, 2022 and 2021, respectively.

Total Stockholder Return

On February 1, 2021, the Compensation Committee awarded performance-based restricted units to the Company’s President and Chief Executive Officer based on Total Stockholder Return metrics (“TSR Performance Units”). The performance-based restricted units will vest upon continued service and achievement of certain stock price levels calculated using a four-year compound annual growth rate and based on the average closing bid price per share of the Company’s common stock measured over a sixty-trading day period (“Stock Price Levels”). Shares will vest in a range of 25% to 350% of the 45,000 target reported units based on achieving specified Stock Price Levels. The vesting end measurement date is February 1, 2025, with earlier vesting determination dates upon a change in control of the Company, involuntary termination of the CEO or twelve months following the achievement of the maximum stock price level. If after February 1, 2023, the President and Chief Executive Officer achieves a Stock Price Level, there will be a vesting determination date the earlier of twelve months thereafter or February 1, 2025.

The following assumptions were used to calculate the grant date fair value of performance-based restricted units with market price condition using the Monte Carlo simulation model:


						February 1, 2021
Risk-free interest rate						0.29%
Dividend yield						—%
Volatility						56.09%
Simulation term						4 years
Forfeiture rate						—%

The Company recorded approximately $1.0 million and $0.2 million of stock compensation expense relating to the TSR Performance Units for the years ended March 31, 2022 and 2021, respectively, included in general and administrative expenses reported in the Consolidated Statements of Operations. As of March 31, 2022 and 2021, there was approximately $2.3 million and $3.1 million, respectively, of unvested compensation expense for the outstanding performance-based restricted stock units related to the February 1, 2021 TSR Performance Units, which is expected to be recognized over a weighted average period of 2.93 years and 3.71 years, respectively.

On August 23, 2021, the Compensation Committee approved the grant of a stock option to the Company’s President and Chief Executive Officer for 100,000 shares of common stock at an exercise price of $57.00 per share. These option shares vest in four equal annual installments measured from the grant date based on the President and Chief Executive Officer’s continued services to the Company. The Black-Scholes option model requires weighted average assumptions to be used for the calculation of the Company’s stock compensation expense. The assumptions used for this grant were: the expected life of the award was 6.02 years; the risk free interest rate was 0.92%; the expected volatility rate was 53.18%; the expected dividend yield was 0.0%; and the expected forfeiture rate was 0%.

On September 7, 2021, the Compensation Committee approved the grant of a stock option to the Company’s Executive Chairman for 65,768 shares of common stock at an exercise price of $60.92 per share. These option shares vest in three equal annual installments measured from the grant date based on the Executive Chairman’s continued services to the Company. The Black-Scholes option model requires weighted average assumptions to be used for the calculation of the Company’s stock compensation expense. The assumptions used for this grant were: the expected life of the award was 5.92 years; the risk free interest rate was 0.96%; the expected volatility rate was 53.45%; the expected dividend yield was 0.0%; and the expected forfeiture rate was 0%.

In May 2021, the Company reacquired 20,132 shares when a participant surrendered already-owned shares of the Company’s common stock to cover the exercise price of an outstanding stock option exercised by the participant. The 20,132 shares surrendered were constructively retired by the Company as of June 30, 2021, which resulted in the non-cash reduction of approximately $1.0 million in accumulated deficit in the Consolidated Statement of Stockholders’ Equity.

The intrinsic value of stock options exercised was approximately $29.5 million, $5.0 million, and $2.4 million for the years ended March 31, 2022, 2021 and 2020, respectively.

Additional information regarding stock options outstanding at March 31, 2022 is as follows:


Exercise Prices					Number Outstanding	Weighted Average Remaining Life in Years	Weighted Average Exercise Price		Options Exercisable	Weighted Average Exercise-Price of Shares Exercisable
$	20.00	—	$	20.00	189,000	2.18	$	20.00	189,000	$	20.00

					1,006,241	5.33	$	32.98	720,180	$	26.11

The fair value of stock options granted is estimated on the date of grant using the Black-Scholes option valuation model. This stock-based compensation expense valuation model requires the Company to make assumptions and judgments regarding the variables used in the calculation. These variables include the expected term, the expected volatility of the Company’s common stock, expected risk-free interest rate, forfeiture rate and expected dividends. The Company calculates an expected term and volatility from the historical volatilities and terms of selected comparable public companies within its industry along with the Company’s short history regarding these variables. The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant for periods corresponding with the expected life of the stock option. The Company estimates its forfeiture rate based on an analysis of its actual forfeitures and will continue to evaluate the appropriateness of the forfeiture rate based on actual forfeiture experience, analysis of employee turnover and other factors. 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 following assumptions were used to calculate the fair value of stock options:

Motorola Investment

On September 15, 2014, Motorola invested $10.0 million to purchase 500,000 Class B Units of the Company’s subsidiary, PDV Spectrum Holding Company, LLC (the “Subsidiary”) (at a price equal to $20.00 per unit). The Company owns 100% of the Class A Units in the Subsidiary. Motorola has the right at any time to convert its 500,000 Class B Units into 500,000 shares of the Company’s common stock. The Company also has the right to force Motorola’s conversion into shares of its common stock. Motorola is not entitled to any assets, profits or distributions from the operations of the Subsidiary. In addition, Motorola’s conversion ratio from Class B Units to shares of the Company’s common stock is fixed on a one-for-one basis and is not dependent on the performance or valuation of either the Company or the Subsidiary. The Class B Units have no redemption or call provisions and can only be converted into shares of the Company’s common stock. Management has determined that this investment does not meet the criteria for temporary equity or non-controlling interest due to the limited rights that Motorola has as a holder of Class B Units and accordingly has presented this investment as part of its permanent equity within Additional Paid-in Capital in the accompanying financial statements. On May 18, 2022, Motorola exercised its right to convert its 500,000 Class B Units into common stock. Refer to Note 14 Subsequent Events for further discussion on this conversion.

The Company has net deferred tax assets, before applying the valuation allowance, of approximately $75.8 million and $62.1 million relating principally to the NOLs as of March 31, 2022 and 2021, 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 incurred consecutive 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, 2022 and 2021, with the exception of the net deferred tax liability of approximately $4.2 million and $3.2 million, respectively, regarding indefinite-lived intangibles.

For Fiscal 2022 and 2021, analysis of the state NOL carryforwards revealed that most of them are not indefinite. The Company recorded $0.6 million and $0.1 million, respectively, of state deferred tax benefit during the year March 31, 2022 and 2021 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.

Commitments and Contingencies Disclosure [Abstract]
Contingencies	Contingencies Contingent Liability 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 private LTE 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 is expected to commence in fiscal year 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 $30.0 million payment, which is due through fiscal year 2024 as the Company delivers 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, including reduced payment amounts and/ or refund of amounts paid and termination rights, if a party fails to perform its contractual obligations. A gain or loss on the sale of spectrum will be recognized for each county once the Company delivers the cleared 900 MHz Broadband Spectrum and the associated broadband licenses to SDG&E. As the Company is required to refund the initial payment in the event of termination or non-delivery of the 900 MHz Broadband Spectrum, it recorded $20.0 million for the upfront payment received from SDG&E in February 2021 as contingent liability in the Consolidated Balance Sheet as of March 31, 2022 and 2021, respectively. 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. COVID-19 Pandemic In March 2020, the World Health Organization declared the outbreak of a novel coronavirus (“COVID-19”) as a pandemic and COVID-19 continues to cause significant disruptions throughout the World. The ultimate extent of the impact of COVID-19 on future financial performance of the Company will depend on ongoing developments, all of which remain uncertain and cannot be predicted. The Company continues to closely monitor the risks posed by COVID-19 and adjusts its practices accordingly. In December 2020, the Company deferred payroll taxes under the Coronavirus Aid Relief and Economic Security Act, which was signed into law on March 27, 2020. The deferral amounted to approximately $0.3 million, which has assisted the Company in managing the financial impact caused by the pandemic. Of the total deferred, approximately $0.2 million was remitted to the IRS during Fiscal 2022, with the remaining amount due by December 31, 2022.

Revenue from Contract with Customer [Abstract]

Revenue

900 MHz Broadband Spectrum Revenue

In December 2020, the Company entered into its first long-term lease agreements of 900 MHz Broadband Spectrum with Ameren. The Ameren Agreements will enable Ameren to deploy a private LTE network in its service territories in Missouri and Illinois, covering approximately 7.5 million people. Each Ameren Agreement is for a term of up to 40 years, consisting of 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 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 licenses. The Company is working with 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 licenses 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 and will be recognized ratably as the Company delivers cleared 900 MHz Broadband Spectrum and the associated broadband licenses by county over the contractual term of approximately 30-years. The revenue recognized for the year ended March 31, 2022 was $0.4 million.

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 a term of up to 40 years, comprised of 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. The Evergy 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 Evergy Agreement. The Company is working with incumbents to clear the 900 MHz Broadband Spectrum allocation covered by the Evergy Agreement. The Company expects to recognize revenue from the Evergy Agreement commencing in the first half of fiscal year 2023. 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 and will be recognized ratably as the Company delivers cleared 900 MHz Broadband Spectrum and the associated broadband licenses by county over the contractual term of approximately 20-years.

Narrowband Spectrum Revenue

In September 2014, Motorola paid the Company an upfront, fully-paid fee of $7.5 million in order to use a portion of the Company’s narrowband spectrum licenses (the “2014 Motorola spectrum agreement”). The payment of the fee is accounted for as deferred revenue on the Company’s consolidated balance sheets and is recognized ratably as the service is provided over the contractual term of approximately ten years. The revenue recognized for the years ended March 31, 2022, 2021 and 2020 was approximately $0.7 million each year.

Service Revenue

The Company has historically derived its service revenue from a fixed monthly recurring unit price per user, with 30-day payment terms, for its pdvConnect, TeamConnect, and Diga-talk service offerings. In December 2018, the Board approved the transfer of various customers under its TeamConnect business to A BEEP and Goosetown along with the support for its pdvConnect business to help reduce operating costs and to allow the Company to focus on its FCC initiatives and future broadband opportunities. On March 31, 2019, these agreements were amended to formally set the transition date for the businesses as April 1, 2019 and to clarify the responsibilities between the parties. Under the terms of the agreement, the Company assigned the intellectual property rights to its TeamConnect and pdvConnect related applications to the LLC.

pdvConnect is a proprietary cloud-based mobile resource management solution which has historically been sold as a separate software-as-a-service offering for dispatch-centric business customers who utilize Tier 1 cellular networks. pdvConnect was historically sold directly by the Company or through two Tier 1 domestic carriers. On April 1, 2020, these customers were transferred to the LLC, except for one Tier 1 domestic carrier. The LLC agreed to pay the Company a certain portion of the recurring revenues from the transferred customers through the term of the agreement.

TeamConnect combines pdvConnect with push-to-talk mobile communication services involving digital network architecture and mobile devices. A BEEP and Goosetown agreed to pay the Company a certain portion of the recurring revenues during the term of the agreements. While the customer remained on the Company’s TeamConnect Metro and Campus Systems (the “MotoTRBO Systems”), the portion of recurring revenues paid by A BEEP and Goosetown was recorded as revenue.

As a result of the completion of the migration to A BEEP and Goosetown in December 2020, service revenue is recorded to other income in the Consolidated Statement of Operations.

Contract Assets

The Company recognizes a contract asset for the incremental costs of obtaining a contract with a customer. These costs include sales commissions. These costs are amortized ratably using the portfolio approach over the estimated customer contract period. The Company will review the contract asset on a periodic basis to determine if an impairment exists, and subsequent to the Company’s adoption of ASU 2016-13, will review the contract assets for potential credit loss exposure. If it is determined that there is an impairment, or a potential credit loss, the Company will expense the contract asset.

As of March 31, 2022 and 2021, the Company incurred commission and stock compensation costs to obtain its long-term 900 MHz Broadband Spectrum lease agreements amounting to approximately $0.3 million and $0.4 million, respectively, which was capitalized and will be amortized over the contractual term of approximately 30-years.

Historically, contract assets include commissions for salespeople and commissions paid to third-party dealers. As a result of transferring customers to A BEEP and Goosetown, all contract and contract acquisition costs were impaired for the year ended March 31, 2020. The Company recorded the impairment by increasing direct cost of revenue amounting to $0.2 million and sales and support expense amounting to $0.3 million for the year ended March 31, 2020.

Intangible Assets

Wireless licenses are considered indefinite-lived intangible assets. Indefinite-lived intangible assets are not subject to amortization but instead are tested for impairment annually, or more frequently if an event indicates that the asset might be impaired. There were no impairment charges related to the Company’s indefinite-lived intangible assets during the years ended March 31, 2022, 2021 and 2020.

During the years ended March 31, 2022 and 2021, the Company entered into agreements with several third parties in multiple U.S. markets to acquire wireless licenses for cash consideration of $17.8 million and $15.6 million, respectively, after receiving FCC approval. As of March 31, 2022 and 2021, the Company recorded initial deposits to incumbents amounting to approximately $8.0 million and $2.3 million, respectively, that are refundable if the FCC does not approve the sale of the spectrum. Of the $8.0 million initial refundable deposit balance as of March 31, 2022, $7.6 million was included in prepaid expenses and other current assets and the remaining $0.4 million in other assets in the Consolidated Balance Sheets. Of the $2.3 million initial refundable deposit balance as of March 31, 2021, $1.9 million was included in prepaid expenses and other current assets and the remaining $0.4 million in other assets in the Consolidated Balance Sheets. As of March 31, 2022 and 2021, the Company recorded deferred charges of $3.4 million and $0.4 million, respectively, related to in-process deals, of which $0.2 million and $0.1 million was recorded in prepaid expenses and other current assets and $3.1 million and $0.3 million, respectively, was recorded in other assets. Once the FCC approves the sale, the Company makes the final payment to the incumbent. Once the final payment is made, both the initial deposit and final payment are transferred to the intangible asset for the wireless licenses.

The nation’s railroads, particularly the major freight lines, operate on six narrowband 900 MHz channels licensed to the Association of American Railroads (“AAR”). Three of these narrowband channels are located in the 900 MHz broadband segment created by the FCC in the Report and Order. As a result, in order to qualify for broadband licenses under the Report and Order, the Company will be required to provide spectrum for the relocation of the AAR channels to narrowband channels outside the 900 MHz broadband segment.

In January 2020, the Company entered into an agreement with the AAR pursuant to which the Company 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 Report and Order provides that the FCC will make the channels associated with these licenses available to the AAR to enable the AAR to relocate their current operations. The Report and Order also provides that the FCC will credit the Company for its cancelled licenses for purposes of determining the Company’s eligibility to secure broadband licenses and the calculation of any Anti-Windfall Payments.

In accordance with the Report and Order and the AAR Agreement, the Company cancelled its licenses in June 2020. Because the Company did not receive any licenses nor monetary reimbursement in exchange for the cancellation, but only credit for purposes of determining its future eligibility and payment obligations for broadband licenses under the Report and Order, the Company recorded a $4.7 million loss from disposal of the intangible assets in the Consolidated Statements of Operations for the year ended March 31, 2021.

In August 2020, the Company closed an agreement with a third party for the exchange of 900 MHz licenses plus approximately $0.3 million for the reprogramming of their equipment. Since the licenses the Company acquired in the exchange were included in the licenses returned to the FCC in accordance with the AAR Agreement above, the $0.3 million for equipment reprogramming was recorded as additional loss from disposal of the intangible assets in the Consolidated Statements of Operations.

In September 2020, the Company closed an agreement with a third party for the exchange of 900 MHz licenses. Under the agreement, the Company received spectrum licenses at their estimated fair value of approximately $0.2 million and a payment of $1.2 million in cash to clear the channels received from incumbents. In January 2018, the Company received $0.6 million as a refundable deposit when the agreement was executed in Fiscal 2018, and the Company is entitled to receive the remaining $0.6 million upon receipt of FCC approval and closing of the agreement in September 2020. Under the agreement, the Company transferred spectrum licenses with book value of approximately $0.3 million to the third party. The Company recognized a $1.1 million gain from disposal of intangible assets in the Consolidated Statement of Operations when the deal closed in September 2020.

In addition, during the year ended March 31, 2020, the Company entered into a barter agreement whereby it provided equipment with a net book value of $21,000 and approximately $15,000 in cash in exchange for wireless licenses valued at approximately $88,000. The Company recorded a corresponding gain of $52,000.

During the year ended March 31, 2022, the Company applied for, and was granted by the FCC, broadband licenses for 21 counties. The Company recorded the new broadband licenses at their estimated accounting cost basis of approximately $15.3 million. In connection with receiving the broadband licenses, the Company disposed of $4.1 million related to the value ascribed to the narrowband licenses it relinquished to the FCC for the same 21 counties. The total carrying value of narrowband licenses included the cost to acquire the original narrowband licenses, Anti-Windfall payments paid to cover the shortfall in each county and the clearing costs. As a result of the exchange of narrowband licenses for broadband licenses, the Company recorded a gain on disposal of intangible assets of $11.2 million, for the year ended March 31, 2022.

A lease is defined as a contract that conveys the right to control the use of identified property, plant or equipment for a period of time in exchange for consideration. On April 1, 2019, the Company adopted ASC 842 and it primarily affected the accounting treatment for operating lease agreements in which the Company is the lessee.

Substantially 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, 2023 through June 30, 2027, 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 May 31, 2022 to April 30, 2028.

Substantially all of the Company’s leases are classified as operating leases, and as such, were previously not recognized on the Company’s Consolidated Balance Sheet. With the adoption of ASC 842, operating lease agreements are required to be recognized on the Consolidated Balance Sheet as ROU assets and corresponding lease liabilities.

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 discount rate for the Company’s operating leases are as follows:


	2022		2021
Weighted average term - operating lease liabilities	3.57 years		4.40 years
Weighted average incremental borrowing rate - operating lease liabilities	13	%	13	%

Rent expense amounted to approximately $2.0 million for the year ended March 31, 2022, of which is included in general and administrative expenses in the Consolidated Statement of Operations.

Rent expense amounted to approximately $2.6 million for the year ended March 31, 2021, of which approximately $1.2 million are included in direct cost of revenue and the remainder of approximately $1.4 million included in general and administrative in the Consolidated Statement of Operations.

Rent expense amounted to approximately $2.7 million for the year ended March 31, 2020, of which approximately $1.7 million are included in direct cost of revenue and the remainder of approximately $1.0 million included in general and administrative in the Consolidated Statement of Operations.

Accounting Policies [Abstract]

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.

Correction of Immaterial Error

In connection with preparing its financial statements for the quarter ended December 31, 2021, the Company determined that it incorrectly accounted for idled assets as Held For Future Use within its Annual Report on Form 10-K for the year ended March 31, 2021, which resulted in an incorrect presentation of the asset classification included in the Property and Equipment footnote within the Notes to the Consolidated Financial Statements. The idled assets should have remained as in-service assets with no change in classification as the idling of these assets is temporary in nature.


	For the year ended March 31, 2021

Network sites and equipment	$	12,547	$	688	$	13,235

Construction in process	10		—		10
Assets held for future use	688		(688)		—
Property and equipment, net	$	3,574	$	—	$	3,574

Reclassifications

Certain amounts previously reported in the Company’s Consolidated Statement of Operations for prior years have been reclassified to conform to the presentation within this Annual Report on Form 10-K. The reclassification includes the consolidation of the restructuring costs line into the general and administrative line within the Company’s Consolidated Statement of Operations.

Cash and Cash Equivalents

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.

Concentrations of Credit Risk

Financial instruments which potentially expose the Company to concentrations of credit risk consist primarily of cash and cash equivalents. The cash balance at times may exceed federally insured limits, however, the Company places its cash and temporary cash investments with financial institutions for which credit loss is not anticipated.

For the year ended March 31, 2022, the Company’s operating revenue was entirely from Motorola Solutions, Inc. (“Motorola”) and Ameren, as discussed in Note 2 Revenue. For the year ended March 31, 2021, the Company had one Tier 1 domestic carrier and one reseller that accounted for approximately 17% of total operating revenues, respectively. For the year ended March 31, 2020, the Company had two domestic carriers and one reseller that accounted for approximately 21% of total operating revenues, respectively.

As of March 31, 2022, the Company does not have an outstanding accounts receivable balance. As of March 31, 2021, the Company had one Tier 1 domestic carrier that accounted for the entire total accounts receivable, which was carried at the invoiced amount.

Allowance for Doubtful Accounts

An allowance for uncollectible receivables is estimated, as required, based on a combination of write-off history, aging analysis and any specific known troubled accounts. The Company reviews its allowance for uncollectible receivables on a quarterly basis. Past due balances meeting specific criteria are reviewed individually for collectability.

Changes in the allowance for doubtful accounts for the years ended March 31, 2022, 2021 and 2020 are summarized below (in thousands):


	2022		2021		2020
Balance at beginning of the year	$	—	$	12	$	77
Bad debt expense	—		—		41
Write-offs	—		(12)		(69)
Recoveries	—		—		(37)
Balance at end of the year	$	—	$	—	$	12

In connection with the Company’s adoption of ASU 2016-13, Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), as discussed below, the Company will continue to monitor its credit loss exposure based on the write-off history, current conditions and future forecasts on the collectability of the accounts.

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 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 in the Consolidated Statement of Operations.

As of March 31, 2022, the Company settled approximately $0.1 million of its obligation to restore the leased premises to its original condition and revised its asset retirement obligations accrual by $17,000 on estimated future cash flows.

As of March 31, 2021, the Company settled approximately $0.2 million of its obligation to restore the leased premises to its original condition and revised its asset retirement obligations accrual by $0.1 million on estimated future cash flows.

Changes in the liability for the asset retirement obligations for the years ended March 31, 2022 and 2021 are summarized below (in thousands):

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

Historically, wireless licenses were tested for impairment on an aggregate basis, consistent with the Company’s dispatch business at a national level. Effective Fiscal 2021, the Company determined that its unit of accounting should be based on geographic markets and that it should test its wireless licenses for impairment based on the individual markets, as the Company will be utilizing the wireless licenses as part of facilitating broadband spectrum networks at an individual 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.

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 are forward-looking and depend on the Company’s ability to successfully apply for broadband licenses and commercialize its 900 MHz Broadband Spectrum.

During Fiscal 2022, the Company changed the date of its annual impairment assessment from March 31, its fiscal year-end, to January 1. For the year ended March 31, 2022, the Company performed a step zero qualitative approach impairment test as of January 1, 2022, for each geographical market to test indefinite-lived intangible assets for impairment by first assessing qualitative factors to determine whether it is more-likely-than-not that the fair value of an indefinite-lived intangible asset is impaired as a basis for determining whether it is necessary to perform quantitative impairment testing. As a result of the step zero test, the Company was not required to perform a step one analysis. As of and for the year ended March 31, 2021, the Company performed a step one quantitative impairment test to determine if the fair value of the licenses exceed the carrying values for each geographical market. Estimated fair value is determined using a market-based approach primarily using the 600 MHz auction price as the Report and Order noted that the FCC will use as a reference the spectrum price based on the average price paid in the FCC’s 600 MHz auction to calculate the Anti-Windfall Payments. For the year ended March 31, 2020, the Company performed a step zero qualitative approach impairment test on an aggregate basis to test indefinite-lived intangible assets for impairment by first assessing qualitative factors to determine whether it is more-likely-than-not that the fair value of an indefinite-lived intangible asset is impaired as a basis for determining whether it is necessary to perform quantitative impairment testing. Based on the results of the impairment tests, there were no impairment charges recorded during the years ended March 31, 2022, 2021 and 2020.

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 new accounting basis, for those acquired from the FCC, or fair value for those acquired from third party, (collectively, the “acquired basis”). The difference between the acquired basis 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 in the Company’s Consolidated Statements of Operations. The acquired basis of spectrum licenses is based on information for which there is little or no observable market data. If the transaction lacks commercial substance or the acquired basis is not measurable, the acquired spectrum licenses are recorded at the carrying value of the spectrum assets transferred, cancelled or exchanged. 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, as defined in the Report and Order, which is considered the accounting basis for the new broadband licenses.

See Note 5 Intangible Assets for a discussion on the Company’s spectrum exchanges during the years ended March 31, 2022 and 2021.

Long-Lived Assets and Right of Use Assets Impairment

The Company evaluates long-lived assets, including 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 year ended March 31, 2022. During the year ended March 31, 2021, the Company recorded an $85,000 non-cash impairment charge for long-lived assets consisting of network site and equipment costs to reduce the carrying values to zero. During the year ended March 31, 2020, the Company recorded a $46,000 non-cash impairment charge for long-lived assets consisting of $35,000 for property and equipment and $11,000 for a right of use asset to reduce the carrying values to zero.

Equity Method Investment

The Company’s 19.5% investment in the TeamConnect LLC (the “LLC”) for which the Company is not the primary beneficiary and does not influence or control the activities that most significantly impact the LLC’s economic performance, are not consolidated and are accounted for under the equity method of accounting. Under the equity method of accounting, the LLC’s accounts are not reflected within the Company’s consolidated balance sheets and statements of operations. The Company’s share of the earnings of the LLC is reported as income (loss) on equity method investment in the Company’s consolidated statements of operations. The Company’s carrying value in an equity method investment is reported as equity method investment on the Company’s consolidated balance sheets.

If the Company’s carrying value in an equity method is reduced to zero, no further losses are recorded in the Company’s consolidated financial statements unless the Company guarantees obligations of the LLC or commits additional funding. When the LLC subsequently reports income, the Company will not record its share of such income until it equals the amount of its share of losses not previously recognized.

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 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

Financial instruments, including cash and cash equivalents, accounts receivable, accounts payable and accrued expenses are carried at cost, which management believes approximates fair value because of the short-term maturity of these instruments.

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, 2023 through June 30, 2027, 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.

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 its 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 and the identified performance obligation has been satisfied.

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. Most of the Company’s performance obligations will be 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 licenses by county to the customer over the contractual term.

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. As a result of the customers being assigned to A BEEP and Goosetown (see Note 3 Revenue below), the Company’s capitalized sales commissions were impaired on April 1, 2019. For the years ended March 31, 2022 and 2021, the Company capitalized commission costs required to obtain long-term 900 MHz Broadband Spectrum lease agreements which will be amortized over the contractual term of approximately 30-years. See Note 3 Revenue for a discussion on the Company’s capitalized contract assets incurred during the period ended March 31, 2022 and 2021.

Direct Cost of Revenue

The Company’s historical direct cost of revenue related to its TeamConnect service offering includes the costs of operating its dispatch network and its cloud-based solutions. With respect to sales of its historical software applications through its wireless carrier partners, direct cost of revenue includes the portion of service revenue retained by its domestic Tier 1 carrier or reseller partners pursuant to its agreements with these parties, which may include network services, connectivity, SMS service, sales, marketing, billing and other ancillary services.

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 $89,000, $19,000 and $33,000 for the years ended March 31, 2022, 2021 and 2020, 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-pricing 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-pricing model. 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.

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 vesting period. The compensation cost for the performance units without market conditions is recognized when the performance criteria are expected to be complete.

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 of directors (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.

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, 2022, 2021 and 2020 are summarized below (in thousands):


	2022		2021		2020
Balance at beginning of the year	$	65,304	$	47,664	$	37,019
Charged to costs and expenses	979		124		2,399
Changes in net loss carryforward and other	13,715		17,516		8,246
Balance at end of the year	$	79,998	$	65,304	$	47,664

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 entities, stock options, restricted stock and warrants are considered to be potentially dilutive securities. Because the Company has reported a net loss for the years ended March 31, 2022, 2021 and 2020, 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 1,343,000, 1,382,000 and 1,440,000 at March 31, 2022, 2021 and 2020, respectively, and have not been included in the dilutive weighted average shares of common stock outstanding, as their effects are anti-dilutive.

Recently Adopted Accounting Guidance

In June 2016, the FASB issued ASU 2016-13, Measurement of Credit Losses on Financial Instruments, and has subsequently modified several areas of the Accounting Standards Codification 326, Financial Instruments – Credit Losses, in order to provide additional clarity and improvements. The new standard requires entities to use a Current Expected Credit Loss impairment model based on expected losses rather than incurred losses. Under this model, an entity would recognize an impairment allowance equal to its current estimate of all contractual cash flows that the entity does not expect to collect from financial assets measured at amortized cost within the scope of the standard. The entity’s estimate would consider relevant information about past events, current conditions and reasonable and supportable forecasts, which will result in recognition of lifetime expected credit losses. As the Company was previously a smaller reporting company, the standard updates would have been effective beginning April 2023, however, due to the transition to a large accelerated filer during the current fiscal year, the updates were effective for the Company as of the fiscal year end 2022. The Company adopted the new standard effective March 31, 2022, and the adoption did not have a material impact on its consolidated financial statements and related disclosures.

Recently Issued Accounting Pronouncements

While there have been accounting standards that have been issued or proposed by the FASB or other standard-setting bodies that do not require adoption until a future date, these updates are not expected to have a material impact on the Company’s consolidated financial statements upon adoption.

Motorola received the Shares by electing to convert 500,000 Class B Units (the “Units”) it held in the Subsidiary. Motorola acquired the Units in September 2014 in connection with a Spectrum Lease Agreement between Motorola and the Subsidiary. Under the Spectrum Lease Agreement, Motorola leased a portion of the Company’s narrowband spectrum, which was held by the Subsidiary, in consideration for an upfront, fully-paid leasing fee of $7.5 million and a $10.0 million investment in the Units. Motorola had the right at any time to convert its Units into the Shares, representing a conversion price of $20.00 per share. The Shares are currently restricted and may not be resold unless the resale is registered under the federal securities laws, or the Shares are sold in compliance with an exemption from the federal registration requirements.

Nature of Operations	Mar. 31, 2022
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of Operations	Nature of Operations Anterix Inc. (the “Company”) is a wireless communications company focused on commercializing its spectrum assets to enable its targeted utility and critical infrastructure customers to deploy private broadband networks, technologies and solutions. The Company is the largest holder of licensed spectrum in the 900 MHz band (896 - 901 / 935 - 940 MHz) with nationwide coverage throughout the contiguous United States, Hawaii, Alaska and Puerto Rico. On May 13, 2020, the Federal Communications Commission (the “FCC”) approved the Report and Order (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. The Report and Order was published in the Federal Register on July 16, 2020, and became effective on August 17, 2020. The Company is now engaged in qualifying for and securing broadband licenses from the FCC. At the same time, the Company is pursuing opportunities to lease the broadband spectrum it secures to its targeted utility and critical infrastructure customers. 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 and McLean, Virginia. Business Developments In December 2020, the Company entered into its first long-term lease agreements of 900 MHz spectrum authorized for broadband use (“900 MHz Broadband Spectrum”), with Ameren Corporation (“Ameren”), (the “Ameren Agreements”). The Ameren Agreements will enable Ameren to deploy a private LTE network in its service territories in Missouri and Illinois, covering approximately 7.5 million people. Each Ameren Agreement is for a term of up to 40 years, consisting of 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. See Note 3 Revenue for further discussion on the Ameren Agreements. In September 2021, the Company entered into a long-term lease agreement of 900 MHz Broadband Spectrum with Evergy Services, Inc. (“Evergy”), (the “Evergy Agreement”). 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 a term of up to 40 years, comprised of 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. See Note 3 Revenue for further discussion on the Evergy Agreement.
