CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

This Quarterly Report on Form 10-Q (the “Quarterly Report”) includes statements of our expectations, intentions, plans, projections, guidance and beliefs that constitute “forward-looking statements.” These forward-looking statements are principally, but not solely, contained in the section captioned “Management’s Discussion and Analysis of Financial Condition and Results of Operations.” These statements include, but are not limited to, statements about our strategies, plans, objectives, expectations, projections, guidance, intentions, expenditures and assumptions and other statements contained herein that are not historical facts. Our forward-looking statements are generally, but not always, accompanied by words such as, but not limited to, “aim,” “anticipate,” “believe,” “can,” “continue,” “could,” “estimate,” “expect,” “goal,” “intend” “may,” “might,” “ongoing,” “plan,” “possible,” “potential,” “predict,” “project,” “seek,” “should,” “strategy,” “target,” “will,” “would” and similar expressions or phrases, or the negative of those expressions or phrases, or other words that convey the uncertainty of future events or outcomes, which are intended to identify forward-looking statements, although not all forward-looking statements contain these words. We have based these forward-looking statements on our current expectations, guidance and projections and related assumptions about future events and financial trends. While our management considers these expectations, guidance, projections and assumptions to be reasonable, they are inherently subject to significant business, economic, competitive, regulatory and other risks, contingencies and uncertainties, most of which are difficult to predict and many of which are beyond our control. There can be no assurance that actual developments will be as we anticipate. Actual results may differ materially from those expressed or implied in these statements as a result of significant risks and uncertainties, including, but not limited to:

•our ability to qualify for and obtain broadband licenses in a timely manner or at all from the Federal Communications Commission (the “FCC”) in accordance with the requirements of the Report and Order approved by the FCC on May 13, 2020 (the “Report and Order”);

•our ability to successfully commercialize our spectrum assets to our targeted utility and critical infrastructure customers, including those customers that are above the Demonstrated Intent threshold, on a timely basis, and on commercially favorable terms consistent with our business plan and assumptions;

•our ability to develop, market and sell new products and services, in addition to our spectrum assets, to our targeted and critical infrastructure customers;

•our ability to correctly estimate our cash receipts, revenues and operating expenses and our future financial needs;

•our ability to achieve our operating and financial projections and guidance;

•our ability to support our future operations and business plans and return capital to our stockholders through our share repurchase program with our existing cash resources and the proceeds we generate from our commercial operations without raising additional capital through the issuance of stock or debt securities;

•the extent and duration of the impact of macroeconomic pressures, including but not limited to pandemics, inflation, regulatory and policy changes, and geopolitical matters, on our business and on our potential customers’ businesses;

•our ability to retune, protect or acquire Covered Incumbent narrowband licenses, including Complex Systems, in a timely manner and on commercially reasonable terms, or at all;

•our ability to satisfy our obligations, including the delivery of cleared spectrum and broadband licenses, and the other contingencies required by our commercial agreements with our customers on a timely basis and on commercially reasonable terms;

•whether federal and state agencies and commissions will support the deployment of broadband networks and services by our targeted customers;

•our ability to maintain any narrowband and broadband licenses that we own, acquire and/or obtain;

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

•our ability to successfully compete against third parties who offer spectrum and communication technologies, products and solutions to our targeted customers;

•our ability to retain executive officers and key personnel and attract, retain and motivate qualified talent;

•our ability to successfully manage our planned growth;

•the ability to develop and sustain a robust market for our common stock;

Table of Contents

•we may not be able to predict, influence or control factors that may cause volatility of our common stock price or cause the value of our common stock to decline;

•the expected timing, the amount of repurchases and the related impact to our common stock relating to our share repurchase program; and

•how the concentrated ownership of our common stock may limit other stockholders’ ability to influence corporate matters.

The matters discussed in these forward-looking statements are subject to risks, uncertainties and other factors that could cause our actual results to differ materially from those projected, anticipated or implied in the forward-looking statements. Many of these risks, uncertainties and other factors are beyond our ability to control, influence, or predict. The most significant of these risks, uncertainties and other factors are described in “Item 1A—Risk Factors” in Part II of this Quarterly Report and in our Annual Report on Form 10-K for the year ended March 31, 2024, filed with the SEC on June 26, 2024. As a result, investors are urged not to place undue reliance on any forward-looking statements. These forward-looking statements reflect our views and assumptions only as of the date such forward-looking statements were made. Except to the limited extent required by applicable law, we undertake no obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise.

1. Nature of Operations and Basis of Presentation

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

Business Developments

In June 2024, the Company entered into a license purchase agreement with Oncor Electric Delivery Company LLC (“Oncor”) for total estimated consideration of $102.5 million under which Oncor will purchase 900 MHz spectrum licenses covering 95 counties to deploy a private wireless broadband network in its transmission and distribution service area (the “Oncor Agreement”).The total payment of $102.5 million comprises an initial payment of $10.0 million received in June 2024 and remaining payments that are due to the Company for each county, at closing. The timing and rights to milestone payments could vary as 900 MHz broadband licenses are granted by the FCC, broadband licenses are assigned to Oncor and incumbents are cleared by the Company. Oncor operates more than 143,000 circuit miles of transmission and distribution lines in Texas, delivering electricity to more than four million homes and businesses across a service territory that has an estimated population of approximately 13 million people. See Note 10 Contingencies and Guaranty for further discussion on the Oncor Agreement.

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”) for interim financial information. Pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”), certain information and footnote disclosures normally included in annual consolidated financial statements prepared in accordance with U.S. GAAP have been condensed or omitted, these unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements and related notes in the Company’s Annual Report on Form 10-K for the fiscal year ended March 31, 2024, filed with the SEC on June 26, 2024 (the “2024 Annual Report”). In the Company’s opinion all normal and recurring adjustments considered necessary for a fair presentation of the financial position, results of operations and cash flows for the periods presented have been included. The Company believes that the disclosures made in the unaudited consolidated interim financial statements are adequate to make the information not misleading. The results of operations for the interim periods presented are not necessarily indicative of the results for the year. The Company is also required to make certain estimates and assumptions that affect the reported amounts. These 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. All significant intercompany accounts and transactions have been eliminated in consolidation.

Revenue allocated to remaining performance obligations was $185.6 million as of June 30, 2024, which will be recognized over the remaining contract terms up to 30 years.

3. Escrow Deposits

Escrow deposits are considered restricted cash as the deposits are restricted from use until the terms of the escrow agreement are met. Escrow deposits are classified as current assets on the Company’s Consolidated Balance Sheets.

In connection with the Lower Colorado River Authority Agreement (the “LCRA Agreement”), the Company and Lower Colorado River Authority (“LCRA”) entered into an escrow agreement.

In December 2023, the Company received $15.0 million, of which $7.5 million was deposited in an escrow account. As of June 30, 2024, the Company’s escrow deposit balance on the Consolidated Balance Sheets is $7.6 million.

4. Intangible Assets

Wireless licenses are considered indefinite-lived intangible assets.

During the three months ended June 30, 2024 and 2023, the Company entered into agreements with several third parties in multiple U.S. markets to acquire, retune or swap wireless licenses for cash consideration (“deals”) and made Anti-Windfall Payments to the US Treasury Department. The initial deposits to incumbents are recorded as spectrum receivable on the Company’s Consolidated Balance Sheets and are refundable if the FCC does not approve the sale, retuning or swap of the spectrum. The initial deposits are transferred to deferred broadband cost or intangible assets in the Company’s Consolidated Balance Sheets, as applicable, upon meeting the relevant deal milestones. The final payments related to closed retuning or swap deals are recorded as deferred broadband costs on the Company’s Consolidated Balance Sheets. The final payments for license purchases or Anti-Windfall Payments are recorded as intangible assets on the Company’s Consolidated Balance Sheets.

Refer to the Company’s 2024 Annual Report for a more complete description of the nature of its related party transactions prior to March 31, 2024. During the three months ended June 30, 2024, the Company did not have any related party transactions.

6. Leases

All the leases in which the Company is the lessee are comprised of corporate office space and tower space. The Company is obligated under certain lease agreements for office space with lease terms expiring on various dates from October 31, 2024 through January 31, 2029, which includes lease extensions for its corporate headquarters ranging from three to ten years. The Company entered into multiple lease agreements for tower space. The lease expiration dates range from November 30, 2024 to June 12, 2031.

Table of Contents

Substantially all of the Company’s leases are classified as operating leases. Operating lease agreements are required to be recognized on the Company’s Consolidated Balance Sheets as right of use (“ROU”) assets and corresponding lease liabilities. ROU assets include any prepaid lease payments and exclude any lease incentives and initial direct costs incurred. Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term. The lease terms may include options to extend or terminate the lease if it is reasonably certain that the Company will exercise that option.

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


	Three months ended June 30,
	2024	2023
Weighted average term - operating lease liabilities	3.66 years	2.77 years
Weighted average incremental borrowing rate - operating lease liabilities	9%	12%

Total lease cost amounted to approximately $0.5 million and $0.5 million, respectively, for the three months ended June 30, 2024 and 2023. Total lease cost is included in general and administrative expenses on the Company’s Consolidated Statements of Operations.

7. Income Taxes

The Company used a discrete effective tax rate method to calculate taxes for the three months ended June 30, 2024 and 2023, which were a result of its inability to use some portion of its federal and state net operating losses (“NOLs”) carryforwards against the deferred tax liability created by the amortization of indefinite-lived intangible assets and the change in the state effective tax rate. The Company determined that applying an estimate of the annual effective tax rate would not provide a reasonable estimate as small changes in estimated “ordinary” loss could result in significant changes in the estimated annual effective tax rate. Accordingly, for the three months ended June 30, 2024, the Company recorded a total tax expense of $1.2 million. For the three months ended June 30, 2023, the Company recorded a total tax benefit of $0.2 million. The effective income tax rates for the three months ended June 30, 2024 and 2023 were 26.5% and 24.9%, respectively. The increase in the effective tax rate was the result of higher state effective tax rate due to taxable income related to customer milestone payments.

The Company’s NOLs generated after March 31, 2018 may be used as an indefinite-lived asset to offset its deferred tax liability but are limited to 80% of future taxable income. The deferred tax liabilities as of June 30, 2024 are approximately $3.3 million for federal and $4.1 million for state. The deferred tax liabilities as of March 31, 2024 were approximately $3.1 million for federal and $3.2 million for state.

8. Stockholders’ Equity

On August 8, 2023 (the “Effective Date”), the Company adopted a new equity-based compensation plan known as the Anterix Inc. 2023 Stock Plan (the “2023 Stock Plan”). The 2023 Stock Plan permits the Company to grant equity compensation awards to employees, consultants and non-employee directors of the Company. As of the Effective Date, no additional awards may be granted under the Anterix Inc. 2014 Stock Plan (the “2014 Stock Plan”). The 2023 Stock Plan authorizes 250,000 shares of common stock of the Company (“Shares”) for grant. Additionally, 388,151 Shares remaining for grant under the 2014 Stock Plan immediately prior to the Effective Date, Shares subject to outstanding stock awards granted under the 2014 Stock Plan that, following the Effective Date, expire or are terminated or cancelled without having been exercised or settled in full, and Shares acquired pursuant to an award subject to forfeiture or repurchase that are forfeited or repurchased by the Company for an amount not greater than the recipient’s purchase price, are issuable under the 2023 Stock Plan. As of June 30, 2024, under the 2023 Stock Plan, 239,900 shares are available for future issuance of which up to 151,838 shares which may be granted upon meeting certain performance levels above 100% for performance stock unit awards.

During the three months ended June 30, 2024 and the year ended March 31, 2024, a total of 190,860 and 266,539 shares, respectively, were issued in connection with the vesting, conversion and or exercise of grants under the Company’s 2014 and 2023 Stock Plan.

Cumulative Spectrum Proceeds Monetized

The performance-based restricted units were to vest on a determination date of June 24, 2024 (“Determination Date”), based on the 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. Due to the timing of the execution of the Oncor Agreement, the Company entered into an amendment agreement, effectively extending the Determination Date to June 27, 2024. The amendment resulted in 15,800 shares vesting based on the CSPM level achieved.

Share Repurchase Program

In September 2023, the Board authorized the 2023 Share Repurchase Program (the “2023 Share Repurchase Program”) pursuant to which the Company may repurchase up to $250.0 million of the Company’s common stock on or before September 21, 2026. The Company may repurchase shares of its common stock via the open market and/or privately negotiated transactions. Repurchases will be made in accordance with applicable securities laws and may be effected pursuant to Rule 10b5-1 trading plans. The manner, timing and amount of any share repurchases will be determined by the Company based on a variety of factors, including proceeds from customer contracts, the timing of which is unpredictable, as well as general business and market conditions, the Company’s capital position, and other strategic considerations. The 2023 Share Repurchase Program does not obligate the Company to repurchase any particular amount of its common stock.

Table of Contents

The Inflation Reduction Act of 2022, which was enacted into law on August 16, 2022, imposed a nondeductible 1% excise tax on the net value of certain stock repurchases made after December 31, 2022. Excise tax accrued for the three months ended June 30, 2024 was approximately $0.1 million.

The following table presents the share repurchase activity for the three months ended June 30, 2024 and 2023 (in thousands, except per share data):


	Three months ended June 30,
	2024		2023

Number of shares repurchased and retired	63		—
Average price paid per share*	$	32.47	$	—
Total cost to repurchase	$	2,027	$	—

*Average price paid per share includes costs associated with the repurchases.

As of June 30, 2024, $234.0 million is remaining under the share repurchase program.

9. Net Income (Loss) Per Share of Common Stock

Basic net income (loss) per common share is calculated by dividing the net income (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 income (loss) per share calculation, stock options and restricted stock units and awards are considered to be potentially dilutive securities. Diluted earnings per share is computed using the treasury stock method.

For the three months ended June 30, 2024 and 2023, there were 215,423 and 193,948 potentially dilutive stock options and restricted stock units outstanding, respectively, excluded from the calculation of diluted weighted-average shares as their effects are anti-dilutive because the Company reported a net loss for the three months ended June 30, 2024 and 2023, respectively.

10. Contingencies and Guaranty

Contingent Liabilities

SDG&E Refund Obligations

In February 2021, the Company entered into an agreement with SDG&E, San Diego Gas & Electric Company, a subsidiary of Sempra Energy (“SDG&E”), to sell 900 MHz Broadband Spectrum throughout SDG&E’s California service territory, including San Diego and Imperial Counties and portions of Orange County (the “SDG&E Agreement,”), for a total payment of $50.0 million. The total payment of $50.0 million is comprised of an initial payment of $20.0 million received in February 2021 and the remaining payments which are due as the Company delivers the relevant cleared 900 MHz Broadband Spectrum and the associated broadband licenses to SDG&E. As the Company is required to refund payments it has received from SDG&E in the event of termination or non-delivery of the specific county’s full 900 MHz Broadband Spectrum, it recorded the initial payments as contingent liability on the Company’s Consolidated Balance Sheets. A reduction in the contingent liability and a gain or loss on the sale of spectrum will be recognized for each county once the Company delivers the full cleared 900 MHz Broadband Spectrum and the associated broadband license(s) to SDG&E.

LCRA Refund Obligation

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

Table of Contents

delivers the full cleared 900 MHz Broadband Spectrum and the associated broadband license(s) to LCRA. See Note 3 Escrow Deposits for further discussion on the escrow deposit.

Oncor Refund Obligation

In June 2024, the Company entered into the Oncor Agreement for a total payment of $102.5 million, to be paid through fiscal year 2026 pursuant to the terms of the agreement. In June 2024, the Company received an initial payment of $10.0 million with remaining payments due to the Company for each county, at closing. The timing and rights to milestone payments could vary as 900 MHz broadband licenses are granted by the FCC, broadband licenses are assigned to Oncor and incumbents are cleared by the Company. As the Company is required to refund the deposit it has received from Oncor in the event of termination or non-delivery of the specific county’s full cleared 900 MHz Broadband Spectrum, it recorded the initial payment as contingent liability on the Company’s Consolidated Balance Sheets. A reduction in the contingent liability and a gain or loss on the sale of spectrum will be recognized for each county once the Company delivers the full cleared 900 MHz Broadband Spectrum and the associated broadband license(s) to Oncor.

Xcel Energy Guaranty

In October 2022, the Company entered into an agreement with Xcel Energy Services Inc. (“Xcel Energy”) providing Xcel Energy dedicated long-term usage of the Company’s 900 MHz Broadband Spectrum for a term of 20 years throughout Xcel Energy’s service territory in eight states (the “Xcel Energy Agreement”). In connection with Xcel Energy Agreement, the Company entered into a guaranty agreement, under which the Company guaranteed the delivery of the relevant 900 MHz Broadband Spectrum and the associated broadband licenses in Xcel Energy’s service territory in eight states along with other commercial obligations. In the event of default or non-delivery of the specific territory’s 900 MHz Broadband Spectrum, the Company is required to refund payments it has received. In addition, to the extent Anterix has performed any obligations, the Company’s liability and remaining obligations under the Xcel Energy Agreement will extend only to the remaining unperformed obligations. The Company recorded $67.1 million in deferred revenue in connection with the prepayments received as of June 30, 2024. The Company commenced delivery of the relevant cleared 900 MHz Broadband Spectrum and the associated broadband leases in the first quarter of fiscal year 2024 and will continue through 2029. As of June 30, 2024, the maximum potential liability of future undiscounted payments under this agreement is approximately $64.4 million.

Litigation

From time to time, the Company may be involved in litigation that arises from the ordinary operations of the business, such as contractual or employment disputes or other general actions. The Company is not involved in any material legal proceedings at this time.

Pandemic and Macroeconomic Conditions

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

11. Concentrations of Credit Risk and Significant Customer

Financial instruments which potentially expose the Company to concentrations of credit risk consist primarily of cash and cash equivalents. The Company places its cash and temporary cash investments with financial institutions for which credit loss is not anticipated. As of June 30, 2024 and March 31, 2024, substantially all of the Company’s cash balance exceeded the federally insured limits. For the three months ended June 30, 2024 and 2023, each of the Company’s customers accounted for greater than 10% of total revenue.

As of June 30, 2024 and March 31, 2024, the Company does not have an outstanding accounts receivable balance.

Summary

Our net loss for the three months ended June 30, 2024 increased by approximately $13.4 million, or 633%, to $15.5 million from $2.1 million for the three months ended June 30, 2023. The increase in net loss was primarily due to the following:

•Spectrum revenues increased by $0.9 million, or 151%, to $1.5 million for the three months ended June 30, 2024 from $0.6 million for the three months ended June 30, 2023. The increase in our spectrum revenue was primarily attributable to revenue recognized in connection with our agreement with Xcel Energy of approximately $0.8 million.

•General and administrative expenses increased by $1.2 million, or 10%, to $12.9 million for the three months ended June 30, 2024 from $11.7 million for three months ended June 30, 2023. The increase primarily resulted from $1.0 million of fiscal 2024 executive bonuses related to the Oncor Agreement deemed fiscal 2025 compensation. Refer to our 2024 proxy statement for our 2024 annual meeting of our stockholders for additional information.

•Sales and support expenses increased by $0.6 million, or 45%, to $1.9 million for the three months ended June 30, 2024 from $1.3 million for three months ended June 30, 2023. The increase primarily resulted from $0.4 higher headcount costs and commissions and $0.3 million fees related to the Oncor Agreement partially offset by $0.1 million lower contract consulting fees.

•Product development expenses increased by $0.7 million, or 64%, to $1.8 million for the three months ended June 30, 2024 from $1.1 million for three months ended June 30, 2023. The increase primarily resulted from $0.5 million higher contract consulting fees and $0.2 million in IT-related costs.

•Gain from disposal of intangible assets, net decreased by $10.7 million, or 99%, to $0.1 million for the three months ended June 30, 2024 from $10.8 million for the three months ended June 30, 2023. During the three months ended June 30, 2024, we exchanged our narrowband license for a broadband license in 1 county. In connection with the exchange, we recorded an estimated accounting cost basis of $0.1 million for the new

Table of Contents

broadband license and relinquished to the FCC narrowband license for the same 1 county with de minimis value. As a result, we recorded a $0.1 million non-monetary gain from disposal of the intangible assets on our Consolidated Statements of Operations. During the three months ended June 30, 2023, we exchanged our narrowband licenses for broadband licenses in 9 counties. In connection with the exchange, we recorded an estimated accounting cost basis of $13.3 million for the new broadband licenses and disposed of $2.5 million related to the value ascribed to the narrowband licenses we relinquished to the FCC for those same 9 counties. As a result, we recorded a $10.8 million non-monetary gain from disposal of the intangible assets on our Consolidated Statements of Operations.

•Interest income increased by $0.3 million, or 80%, to $0.7 million for the three months ended June 30, 2024 as compared to $0.4 million for three months ended June 30, 2023. The increase was primarily attributable to a higher cash balance.

•Income tax increased by $1.5 million, or 609%, to $1.2 million for the three months ended June 30, 2024 as compared to income tax benefit of $0.2 million for three months ended June 30, 2023. The increase was primarily attributable to higher state effective tax rate due to taxable income related to customer milestone payments.

Liquidity and Capital Resources

Our principal source of liquidity is our cash and cash equivalents generated from customer contract proceeds. At June 30, 2024, we had cash and cash equivalents of $51.7 million.

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

Cash Flows from Operating, Investing and Financing Activities


	Three months ended June 30,
(in thousands)	2024		2023
	(Unaudited)		(Unaudited)
Net cash used in operating activities	$	(2,361)	$	(8,209)
Net cash used in investing activities	$	(5,400)	$	(5,195)
Net cash used in financing activities	$	(1,071)	$	(745)

Net cash used in operating activities

Our principal source of cash provided by operating activities is our customer contract proceeds in the form of advanced payments. For spectrum revenue agreements, we record these advanced payments as deferred revenue on our Consolidated Balance Sheets and recognize revenue over the term of the lease, which is typically 20 to 30 years. For spectrum sale agreements, we record advanced payments as a contingent liability on our Consolidated Balance Sheets and derecognize this liability upon closing of the sale along with recording a gain or loss on sale. In addition, our cash flows reflect a non-cash gain or loss on disposal of intangible assets for the difference in cost basis as we exchange narrowband licenses for

Table of Contents

broadband licenses. We expect net cash provided by (used in) operating activities to be affected by the progress on our customer agreements as well as changes in other operating assets and liabilities. The following represents our changes in net cash used in operating activities for the three months ended June 30, 2024 and 2023.

Net cash used in operating activities was approximately $2.4 million for the three months ended June 30, 2024. The net cash used in operating activities for the three months ended June 30, 2024 was primarily due to the following:

•$15.5 million decrease related to our operating loss, which includes $5.9 million of non-cash items (refer to the Results of Operations);

•$1.6 million decrease in accounts payable and accrued expenses primarily due to annual bonus payments;

•$1.5 million decrease in deferred revenue due to revenue recognition in connection with the delivery of cleared 900 MHz Broadband Spectrum; and

•$10.0 million increase in contingent liability related to the Oncor Agreement.

Net cash used in operating activities was approximately $8.2 million for the three months ended June 30, 2023. The net cash used in operating activities for the three months ended June 30, 2023 was primarily due to the following:

•$2.1 million decrease related to our operating loss, which includes $6.3 million of non-cash items (refer to the Results of Operations); and

•$0.6 million decrease in deferred revenue in connection with revenue recognized for the delivery of cleared 900 MHz Broadband Spectrum.

Net cash used in investing activities

Our principal outflow of cash used in investing activities is our purchases of intangible assets, including refundable deposits, retuning costs and swaps, which represent our spectrum clearing efforts as we work toward the conversion from narrowband to broadband spectrum. The purchases of intangible assets may be offset by current period cash proceeds from the sale of intangible assets, with a potential non-cash derecognition of the contingent liability for any proceeds received and recognized in operating activities in a prior period. We expect net cash provided by (used in) investing activities to be affected by the timing of our spectrum clearing efforts and the closing of our sale transactions and the related transfer of broadband licenses. The following represents our changes in net cash used in investing activities for the three months ended June 30, 2024 and 2023.

Net cash used in investing activities was $5.4 million and $5.2 million for the three months ended June 30, 2024 and 2023, respectively. For the three months ended June 30, 2024, net cash used in investing activities was from $5.4 million payments made to acquire, swap or retune wireless licenses in markets across the United States. For the three months ended June 30, 2023, net cash used in investing activities was primarily from $5.2 million payments made to acquire, swap or retune wireless licenses in markets across the United States.

Net cash used in financing activities

Our principal outflow of cash used in financing activities is a result of our equity transactions, including repurchases of common stock and taxes and fees associated with the issuance of restricted stock awards, offset by proceeds from stock options exercised in the period. We expect net cash used in financing activities to be affected by the timing of future equity transactions including the timing of our repurchases of common stock. The following represents our changes in net cash used in financing activities for the three months ended June 30, 2024 and 2023.

Net cash used in financing activities was $1.1 million and $0.7 million for the three months ended June 30, 2024 and 2023, respectively. For the three months ended June 30, 2024, net cash used in financing activities was primarily for the repurchases of common stock of $2.0 million, payments of withholding tax on net issuance of restricted stock of $0.7 million, partially offset by the proceeds from stock option exercises of $1.6 million. For the three months ended June 30, 2023, net cash used in financing activities was primarily for payments of withholding tax on net issuance of restricted stock of $0.8 million, partially offset by the proceeds from stock option exercises of $7 thousand.

Material Cash Requirements

Our future capital requirements will depend on many factors, including: costs and time related to the commercialization of our spectrum assets; and our ability to sign customer contracts and generate revenues from the license or transfer of any broadband licenses we secure; our ability to timely deliver broadband licenses and clear spectrum to our customers in accordance with our contractual obligation; any requirement to refund payments or pay penalties if we do not satisfy our contractual obligations; the timeline and costs to acquire broadband licenses pursuant to the Report and Order, including

the costs to acquire additional spectrum, the costs related to retuning, or swapping spectrum held by 900 MHz site-based licensees in the broadband segment that is required under section 90.621(b) to be protected by a broadband licensee with a base station at any location within the county, or any 900 MHz geographic-based SMR licensee in the broadband segment whose license area completely or partially overlaps the county, and the costs of paying Anti-Windfall Payments to the U.S. Treasury.

We are obligated under certain lease agreements for office space with lease terms expiring on various dates from October 31, 2024 through January 31, 2029, which includes a three to ten-year lease extension for our corporate headquarters. We have also entered into multiple lease agreements for tower space related to our spectrum holdings. The lease expiration dates range from November 30, 2024 to June 12, 2031. Total estimated payments for these lease agreements are approximately $6.0 million (exclusive of real estate taxes, utilities, maintenance and other costs borne by us). We also have an obligation to clear the tower site locations, for which we recorded an asset retirement obligation (the “ARO”). Total estimated payments as a result of the ARO is approximately $0.7 million. In addition to the lease payments and ARO for our tower site locations, we entered into agreements with several third parties in multiple U.S. markets to acquire, retune or swap wireless licenses for cash consideration (“deals”). As of June 30, 2024, our total estimated future payments for these agreements with incumbents are approximately $11.1 million.

Xcel Energy Guaranty

In October 2022, we entered into an agreement with Xcel Energy Services Inc. (“Xcel Energy”) providing Xcel Energy dedicated long-term usage of our 900 MHz Broadband Spectrum for a term of 20 years throughout Xcel Energy’s service territory in eight states (the “Xcel Energy Agreement”). In connection with Xcel Energy Agreement, we entered into a guaranty agreement, under which we guaranteed the delivery of the relevant 900 MHz Broadband Spectrum and the associated broadband licenses in Xcel Energy’s service territory in eight states along with other commercial obligations. In the event of default or non-delivery of the specific territory’s 900 MHz Broadband Spectrum, we are required to refund payments we have received. In addition, to the extent we have performed any obligations, our liability and remaining obligations under the Xcel Energy Agreement will extend only to the remaining unperformed obligations. We recorded $67.1 million in deferred revenue in connection with the prepayments received as of June 30, 2024. We commenced delivery of the relevant cleared 900 MHz Broadband Spectrum and the associated broadband leases in the first quarter of fiscal year 2024 and will continue through 2029. The revenue recognized for the three months ended June 30, 2024, was approximately $0.8 million. As of June 30, 2024, the maximum potential liability of future undiscounted payments under this agreement is approximately $64.4 million.

Share Repurchase Program

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

The following table presents the share repurchase activity for the three months ended June 30, 2024 and 2023 (in thousands, except per share data):


	Three months ended June 30,

Off-balance sheet arrangements

As of June 30, 2024 and March 31, 2024, we did not have and do not have any relationships with unconsolidated entities or financial partnerships that were established for the purpose of facilitating off-balance sheet arrangements, as defined in the rules and regulations of the SEC.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

Interest Rate Risk

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

Foreign Currency Exchange Rate Fluctuations

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

Inflation Risk

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

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

Item 4. Controls and Procedures

Disclosure Controls and Procedures

Our management, with the participation of our President and Chief Executive Officer and our Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures (as such term is defined in Rules 13a-15(e) of the Exchange Act) as of the end of the period covered by this Quarterly Report. Based on that evaluation, our management, including our President and Chief Executive Officer and our Chief Financial Officer, concluded that our disclosure controls and procedures were effective as of the end of such period.

Changes in Internal Control over Financial Reporting

In connection with the evaluation required by Exchange Act Rule 13a-15(d), our management, including our President and Chief Executive Officer and our Chief Financial Officer, concluded that no changes in our internal control over financial reporting occurred during the period covered by this report that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Inherent Limitations on Effectiveness of Controls

Our management, including our President and Chief Executive Officer and our Chief Financial Officer, do not expect that our disclosure controls or our internal control over financial reporting will prevent or detect all error and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system’s objectives will be met. The design of a control system must reflect the fact that there are resource

Table of Contents

constraints and that the benefits of controls must be considered relative to their costs. Further, because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud, if any, have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty and that breakdowns can occur because of simple error or mistake. Controls can also be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the controls. The design of any system of controls is based in part on certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Projections of any evaluation of the effectiveness of controls to future periods are subject to risks. Over time, controls may become inadequate because of changes in conditions or deterioration in the degree of compliance with policies or procedures.

PART II – OTHER INFORMATION

Item 1. Legal Proceedings.

We are not involved in any material legal proceedings.

Item 1A. Risk Factors.

In evaluating us and our common stock, we urge you to carefully consider the risks and other information in this Quarterly Report as well as the risk factors disclosed in our 2024 Annual Report. There have been no material changes from the risk factors as previously disclosed in our 2024 Annual Report. Any of the risks discussed in this Quarterly Report, if any, and in our 2024 Annual Report, as well as additional risks and uncertainties not currently known to us or that we currently deem immaterial, could materially and adversely affect our results of operations or financial condition.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds.

Purchase of Equity Securities by the Issuer and Affiliated Purchasers

The following table provides information with respect to purchases of our common stock by the Company or any “affiliated purchaser” as defined in Rule 10b-18(a)(3) under the Exchange Act, during the three months ended June 30, 2024.

Nature of Operations and Basis of Presentation	Jun. 30, 2024
Accounting Policies [Abstract]
Nature of Operations and Basis of Presentation	Nature of Operations and Basis of Presentation Anterix Inc (the “Company”) is the utility industry’s partner, empowering enhanced visibility, control and security for a modern grid. The Company’s vision is to deliver secure, scalable solutions enabled by private wireless broadband connectivity, for the benefit of utilities and the communities that they serve. As the largest holder of licensed spectrum in the 900 MHz band (896-901/935-940 MHz) throughout the contiguous United States, plus Hawaii, Alaska and Puerto Rico, the Company is uniquely positioned to deliver solutions that support secure, resilient and customer-controlled operations. The Company is focused on commercializing its spectrum assets and expanding the benefits and solutions it offers to enable the Company’s targeted utility and critical infrastructure customers to deploy private broadband networks. Business Developments In June 2024, the Company entered into a license purchase agreement with Oncor Electric Delivery Company LLC (“Oncor”) for total estimated consideration of $102.5 million under which Oncor will purchase 900 MHz spectrum licenses covering 95 counties to deploy a private wireless broadband network in its transmission and distribution service area (the “Oncor Agreement”).The total payment of $102.5 million comprises an initial payment of $10.0 million received in June 2024 and remaining payments that are due to the Company for each county, at closing. The timing and rights to milestone payments could vary as 900 MHz broadband licenses are granted by the FCC, broadband licenses are assigned to Oncor and incumbents are cleared by the Company. Oncor operates more than 143,000 circuit miles of transmission and distribution lines in Texas, delivering electricity to more than four million homes and businesses across a service territory that has an estimated population of approximately 13 million people. See Note 10 Contingencies and Guaranty for further discussion on the Oncor Agreement. 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”) for interim financial information. Pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”), certain information and footnote disclosures normally included in annual consolidated financial statements prepared in accordance with U.S. GAAP have been condensed or omitted, these unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements and related notes in the Company’s Annual Report on Form 10-K for the fiscal year ended March 31, 2024, filed with the SEC on June 26, 2024 (the “2024 Annual Report”). In the Company’s opinion all normal and recurring adjustments considered necessary for a fair presentation of the financial position, results of operations and cash flows for the periods presented have been included. The Company believes that the disclosures made in the unaudited consolidated interim financial statements are adequate to make the information not misleading. The results of operations for the interim periods presented are not necessarily indicative of the results for the year. The Company is also required to make certain estimates and assumptions that affect the reported amounts. These 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. All significant intercompany accounts and transactions have been eliminated in consolidation.

Income Taxes	3 Months Ended
Income Taxes	Jun. 30, 2024
Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company used a discrete effective tax rate method to calculate taxes for the three months ended June 30, 2024 and 2023, which were a result of its inability to use some portion of its federal and state net operating losses (“NOLs”) carryforwards against the deferred tax liability created by the amortization of indefinite-lived intangible assets and the change in the state effective tax rate. The Company determined that applying an estimate of the annual effective tax rate would not provide a reasonable estimate as small changes in estimated “ordinary” loss could result in significant changes in the estimated annual effective tax rate. Accordingly, for the three months ended June 30, 2024, the Company recorded a total tax expense of $1.2 million. For the three months ended June 30, 2023, the Company recorded a total tax benefit of $0.2 million. The effective income tax rates for the three months ended June 30, 2024 and 2023 were 26.5% and 24.9%, respectively. The increase in the effective tax rate was the result of higher state effective tax rate due to taxable income related to customer milestone payments. The Company’s NOLs generated after March 31, 2018 may be used as an indefinite-lived asset to offset its deferred tax liability but are limited to 80% of future taxable income. The deferred tax liabilities as of June 30, 2024 are approximately $3.3 million for federal and $4.1 million for state. The deferred tax liabilities as of March 31, 2024 were approximately $3.1 million for federal and $3.2 million for state.

Net Income (Loss) Per Share of Common Stock	Jun. 30, 2024
Earnings Per Share [Abstract]
Net Income (Loss) Per Share of Common Stock	Net Income (Loss) Per Share of Common Stock Basic net income (loss) per common share is calculated by dividing the net income (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 income (loss) per share calculation, stock options and restricted stock units and awards are considered to be potentially dilutive securities. Diluted earnings per share is computed using the treasury stock method. For the three months ended June 30, 2024 and 2023, there were 215,423 and 193,948 potentially dilutive stock options and restricted stock units outstanding, respectively, excluded from the calculation of diluted weighted-average shares as their effects are anti-dilutive because the Company reported a net loss for the three months ended June 30, 2024 and 2023, respectively.

Contingencies and Guaranty	Jun. 30, 2024
Commitments and Contingencies Disclosure [Abstract]
Contingencies and Guaranty	Contingencies and Guaranty Contingent Liabilities SDG&E Refund Obligations In February 2021, the Company entered into an agreement with SDG&E, San Diego Gas & Electric Company, a subsidiary of Sempra Energy (“SDG&E”), to sell 900 MHz Broadband Spectrum throughout SDG&E’s California service territory, including San Diego and Imperial Counties and portions of Orange County (the “SDG&E Agreement,”), for a total payment of $50.0 million. The total payment of $50.0 million is comprised of an initial payment of $20.0 million received in February 2021 and the remaining payments which are due as the Company delivers the relevant cleared 900 MHz Broadband Spectrum and the associated broadband licenses to SDG&E. As the Company is required to refund payments it has received from SDG&E in the event of termination or non-delivery of the specific county’s full 900 MHz Broadband Spectrum, it recorded the initial payments as contingent liability on the Company’s Consolidated Balance Sheets. A reduction in the contingent liability and a gain or loss on the sale of spectrum will be recognized for each county once the Company delivers the full cleared 900 MHz Broadband Spectrum and the associated broadband license(s) to SDG&E. LCRA Refund Obligation In April 2023, the Company entered into the LCRA Agreement for a total payment of $30.0 million, to be paid through fiscal year 2026 pursuant to the terms of the agreement. In December 2023, the Company received $15.0 million in milestone payments, of which $7.5 million was deposited in an escrow account. The remaining payments are due as the Company delivers the relevant cleared 900 MHz Broadband Spectrum and the associated broadband licenses to LCRA. As the Company is required to refund the deposit it has received from LCRA in the event of termination or non-delivery of the specific county’s full cleared 900 MHz Broadband Spectrum, it recorded the initial payments as contingent liability on the Company’s Consolidated Balance Sheets. A reduction in the contingent liability and a gain or loss on the sale of spectrum will be recognized for each county once the Company delivers the full cleared 900 MHz Broadband Spectrum and the associated broadband license(s) to LCRA. See Note 3 Escrow Deposits for further discussion on the escrow deposit. Oncor Refund Obligation In June 2024, the Company entered into the Oncor Agreement for a total payment of $102.5 million, to be paid through fiscal year 2026 pursuant to the terms of the agreement. In June 2024, the Company received an initial payment of $10.0 million with remaining payments due to the Company for each county, at closing. The timing and rights to milestone payments could vary as 900 MHz broadband licenses are granted by the FCC, broadband licenses are assigned to Oncor and incumbents are cleared by the Company. As the Company is required to refund the deposit it has received from Oncor in the event of termination or non-delivery of the specific county’s full cleared 900 MHz Broadband Spectrum, it recorded the initial payment as contingent liability on the Company’s Consolidated Balance Sheets. A reduction in the contingent liability and a gain or loss on the sale of spectrum will be recognized for each county once the Company delivers the full cleared 900 MHz Broadband Spectrum and the associated broadband license(s) to Oncor. Xcel Energy Guaranty In October 2022, the Company entered into an agreement with Xcel Energy Services Inc. (“Xcel Energy”) providing Xcel Energy dedicated long-term usage of the Company’s 900 MHz Broadband Spectrum for a term of 20 years throughout Xcel Energy’s service territory in eight states (the “Xcel Energy Agreement”). In connection with Xcel Energy Agreement, the Company entered into a guaranty agreement, under which the Company guaranteed the delivery of the relevant 900 MHz Broadband Spectrum and the associated broadband licenses in Xcel Energy’s service territory in eight states along with other commercial obligations. In the event of default or non-delivery of the specific territory’s 900 MHz Broadband Spectrum, the Company is required to refund payments it has received. In addition, to the extent Anterix has performed any obligations, the Company’s liability and remaining obligations under the Xcel Energy Agreement will extend only to the remaining unperformed obligations. The Company recorded $67.1 million in deferred revenue in connection with the prepayments received as of June 30, 2024. The Company commenced delivery of the relevant cleared 900 MHz Broadband Spectrum and the associated broadband leases in the first quarter of fiscal year 2024 and will continue through 2029. As of June 30, 2024, the maximum potential liability of future undiscounted payments under this agreement is approximately $64.4 million. Litigation From time to time, the Company may be involved in litigation that arises from the ordinary operations of the business, such as contractual or employment disputes or other general actions. The Company is not involved in any material legal proceedings at this time. Pandemic and Macroeconomic Conditions Recent macroeconomic events, inflation and geopolitical matters, have increased operating costs or resulted in delays in customer contracting or impacted the availability of equipment necessary for the deployment of the Company’s target customers’ planned PLTE projects. The Company continues to closely monitor these risks. Although difficult to quantify, the Company believes the current macroeconomic environment, including inflation, may have an adverse effect on the Company’s target customers’ businesses, which may harm the Company’s commercialization efforts and negatively impact the Company’s revenues and liquidity. If the Company is not able to control its operating costs or if the Company’s commercialization efforts are slowed or negatively impacted, continued periods of high inflation could have a material adverse effect on the Company’s business, operating results and financial condition.
