Cautionary Statement Regarding Forward-Looking Statements

This Quarterly Report on Form 10-Q (or the “Report”) contains forward-looking statements relating to, among other matters, the Company’s future financial performance, business goals and objectives, and results of operations, and management’s plans, expectations and strategy for the future. These forward-looking statements are based on estimates, projections, beliefs, and assumptions and are not guarantees of future events or results. Actual future events and results could differ materially from the events and results indicated in these statements as a result of many factors, including, among others: (1) the general performance of our operations, including operating margins, revenues, capital expenditures, the impact of cost savings initiatives and the retention of and future growth of our subscriber base; (2) our ability to complete the pending Tower Portfolio Transaction (as defined below) and realize the anticipated benefits thereof; (3) our reliance on a limited number of key suppliers and vendors for timely supply of equipment and services relating to our network infrastructure; (4) our ability to satisfy the needs and demands of our major carrier customers; (5) our ability to realize expansion plans for our fiber markets; (6) the adequacy and expansion capabilities of our network capacity and customer service system to support our customer growth; (7) our ability to efficiently and cost-effectively upgrade our networks and information technology platforms to address rapid and significant technological changes in the telecommunications industry; (8) continued access to capital and credit markets on terms we deem favorable; (9) government subsidy program availability and regulation of the our businesses, which may impact the our telecommunications licenses, our revenues and operating costs; (10); the impact (if any) of geopolitical instability and US military presence in the Caribbean; (11) our ability to successfully transition our US Telecom business away from wholesale mobility to other carrier and consumer-based services; (12) ongoing risk of an economic downturn, political, geopolitical and other risks and opportunities impacting our operations, including those resulting from changes and uncertainties related to trade policies or tariff regulations, financial market volatility and disruption, uncertain economic conditions in the US and abroad, inflationary concerns, and other macroeconomic headwinds including increased costs and supply chain disruptions; (13) management transitions, and the loss of, or an inability to recruit skilled personnel in our various jurisdictions, including key members of management; (14) our ability to find investment or acquisition or disposition opportunities that fit our strategic goals; (15) the occurrence of weather events and natural catastrophes and our ability to secure the appropriate level of insurance coverage and the impact of such events on the timing of project implementation and corresponding revenue; and (16) increased competition. These and other additional factors that may cause actual future events and results to differ materially from the events and results indicated in the forward-looking statements above are set forth more fully under Item 1A “Risk Factors” of the Company’s Annual Report on Form 10-K for the year ended December 31, 2025, filed with the Securities and Exchange Commission (“SEC”) on March 16, 2026, and the other reports the Company files from time to time with the SEC.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

1.ORGANIZATION AND BUSINESS OPERATIONS

The Company is a leading provider of digital infrastructure and communications services with a strategic focus on rural and remote markets in the United States (“US”), and internationally, including Bermuda and the Caribbean region.

The Company has developed significant operational capabilities and resources that enhance the performance of its local market operations. The Company’s operating subsidiaries benefit from this shared expertise, which allows them to deliver improved service quality and achieve greater economies of scale than would typically be possible in the smaller markets the Company serves. The Company provides centralized management, technical, financial, regulatory, and marketing support to these operating subsidiaries and typically receive a management fee based on a percentage of their revenues. The intercompany fees are eliminated in the Company’s consolidated financial results.

The Company uses the cash generated from its operations to repay debt and increase liquidity, reinvest the Company’s network and service operations, fund capital expenditures, return value to stockholders through dividends or share repurchases, and to pursue strategic transactions. The Company continuously evaluates both domestic and international opportunities that align with its long-term goal of generating sustained excess operating cash flows.

For additional information regarding the Company’s reportable segments and geographic distribution of revenues and assets, please refer to Notes 1 and 13 of the Consolidated Financial Statements included in this Report.

As of March 31, 2026, the Company offered the following services to its customers:

Fixed Telecommunications Services (“Fixed Services”).

In select markets, fixed services also include video offerings and revenue derived from support under certain government programs.

Carrier Telecommunication Services (“Carrier Services”). The Company offers infrastructure services to other telecommunications providers, including the leasing of critical network infrastructure such as towers and transport facilities, wholesale roaming, site maintenance and international long-distance services.

Mobile Telecommunications Services (“Mobility Services”). The Company offers mobile communications services over its wireless networks, including voice, messaging and data services along with related equipment, such as handsets, to both business and consumer customers.

Managed Services. The Company delivers information technology solutions, including network management, application support and infrastructure services to complement its fixed telecommunications services in its existing markets for the purpose of supporting both enterprise and residential users.

Through March 31, 2026, the Company identified two operating segments to manage and review its operations, as well as to support investor presentations of its results. These operating segments are as follows:

2. BASIS OF PRESENTATION

The accompanying condensed consolidated financial statements have been prepared by the Company pursuant to the rules and regulations of the SEC. The financial information included herein is unaudited; however, the Company believes such information and the disclosures herein are adequate to make the information presented not misleading and reflect all adjustments (consisting only of normal recurring adjustments) that are necessary for a fair statement of the Company’s financial position and results of operations for the periods described therein. The year-end condensed balance sheet data was derived from audited financial statements but does not include all disclosures required by accounting principles generally accepted in the United States of America (“GAAP”). Results of interim periods may not be indicative of results for the full year. These condensed consolidated financial statements and related notes should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2025, filed with the SEC on March 16, 2026.

The condensed consolidated financial statements include the accounts of the Company, its subsidiaries in which the Company holds controlling interests and certain entities which are consolidated in accordance with the provisions of the Financial Accounting Standards Board’s (“FASB”) authoritative guidance on the consolidation of variable interest entities, since it is determined that the Company is the primary beneficiary of these entities.

Recent Accounting Pronouncements

In November 2024, the FASB issued Accounting Standards Update (“ASU”) No. 2024-03, “Disaggregation of Income Statements Expenses (DISE)” (“ASU 2024-03”), which requires that a public entity provide additional disclosure of the nature of expenses included in the income statement. The new standard requires disclosures about specific types of expenses included in the expense captions presented on the face of the income statement as well as disclosures about selling expenses. ASU 2024-03 will be effective for annual periods beginning after December 15, 2026, and interim periods beginning after December 15, 2027, with retrospective application. The standard allows early adoption of these requirements and the Company is currently evaluating the disclosure impacts of adoption.

In September 2025, the FASB issued ASU No. 2025-06, “Intangibles - Goodwill and Other – Internal Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software” (“ASU 2025-06”). ASU 2025-06 removes references to software development project stages and requires software cost capitalization when two criteria are met (i) management has authorized and committed to funding the project, and (ii) it is probable that the project will be completed and used as intended. ASU 2025-06 will be effective for annual reporting periods beginning after December 15, 2027. The Company is currently evaluating the impacts of its adoption.

In July 2025, the FASB issued ASU No. 2025-05, “Measurement of Credit Losses for Accounts Receivable and Contract Assets” (“ASU 2025-05”), which provided a practical expedient for all entities to assume current conditions as of the balance sheet date will remain through the reasonable and supportable forecast period for eligible assets. Entities were required to adjust the historical data used in the estimation of credit losses to reflect current conditions. The Company prospectively adopted ASU 2025-05, effective January 1, 2026. The adoption of ASU 2025-05 did not have a material impact on its disclosures.

In December 2025, the FASB issued ASU No. 2025-10, “Government Grants (Topic 832) – Accounting for Government Grants Received by Business Entities” (“ASU 2025-10”), which provides specific authoritative guidance for recognition, measurement, and presentation of government grants. ASU 2025-10 is effective on a prospective or retrospective basis for annual reporting periods beginning after December 15, 2028, and interim reporting periods within those annual reporting periods. The standard allows for early adoption of these requirements, and the Company is currently evaluating the impacts of its adoption.

In December 2025, the FASB issued ASU No. 2025-11, “Interim Reporting (Topic 270) – Narrow-Scope Improvements” (“ASU 2025-11”), which provides additional guidance on disclosures that should be provided for interim reporting periods. ASU 2025-11 is effective on a prospective or retrospective basis for interim reporting periods within annual reporting periods beginning after December 15, 2027. The standard allows for early adoption of these requirements, and the Company is currently evaluating the impacts of its adoption.

3. DISPOSITIONS

US Telecom

On February 11, 2026, through certain Commnet subsidiaries, the Company entered into a Purchase and Sale Agreement (the “Transaction Agreement”) with EIP Holdings IV, LLC, an affiliate of Everest Infrastructure Partners, Inc. (“Everest”), to sell approximately 214 tower portfolio sites (representing the substantial majority of our Commnet tower portfolio and operations (the “Tower Portfolio”)) to Everest for up to $297 million in cash consideration, subject to certain adjustments and prorations (the “Tower Portfolio Transaction”).

The Tower Portfolio Transaction may be completed in one or more closings. The Transaction Agreement sets forth certain conditions that must be satisfied prior to the conveyance of tower sites at a closing. During the period between signing and the initial closing, the parties will determine which tower sites within the Tower Portfolio have satisfied such conditions and are ready to be conveyed at the initial closing, which sites have not yet satisfied all such conditions but for which Everest is prepared to assume management pending satisfaction of such conditions, and which

12

Table of Contents

sites are not yet constructed or are subject to other conditions that will continue to be managed by the Company until such conditions are satisfied.

At the initial closing, the Company will enter into, among other ancillary agreements, (i) a management agreement for certain sites, (ii) master lease agreements, pursuant to which the Company will lease the requisite ground, tower, or other space of the conveyed tower site for our continued use, and (iii) a preferred backhaul agreement whereby the Company will become the preferred backhaul provider with respect to the conveyed tower sites.

The Transaction Agreement contains customary representations, warranties, covenants, and indemnities by each of the parties, and requires the receipt of certain consents and approvals prior to a closing. The waiting period required under the Hart-Scott Rodino Act of 1976 with respect to the Tower Portfolio Transaction expired in early March 2026. If the Transaction Agreement is terminated under certain circumstances that are not the fault of the Company, it will receive a termination fee equal to approximately $14.9 million.

The Company continues to expect the initial closing of the Tower Portfolio Transaction to occur in the second quarter of 2026, generating gross proceeds of approximately $250 million to $270 million. Subsequent closings, totaling approximately $27 million to $47 million, are anticipated to occur over the twelve months following the initial closing, subject to the achievement of specified construction and operational milestones at designated sites within the Tower Portfolio.

The Company now currently anticipates that approximately 40-55% of the amount of proceeds to be received at the initial closing will be subject to post-closing resolution, due to delays in obtaining ground lease assigning consents from government and tribal agencies, as well as other conditions being satisfied with respect to such sites.

As of March 31, 2026, the Company recorded its Tower Portfolio assets and liabilities as held for sale. The assets and liabilities recorded as held for sale consist of the following (in thousands):

Equity Investments

During the year ended December 31 2025, the Company entered into an agreement to sell its India solar investment. As a result of this transaction, the Company recorded its equity investment as held for sale at December 31, 2025. The transaction price was reduced in 2026 resulting in a $2.6 million impairment being recorded in other income (expense) during the three months ended March 31, 2026. The investment’s remaining book value of $8.6 million continues to be recorded as held for sale in the Company’s March 31, 2026 balance sheet.

The Company expects to satisfy approximately 48% of the remaining performance obligations and recognize the transaction price within 24 months and approximately $60 million annually from 2028 through 2032. The Company omits performance obligations associated with a contract with a duration of one year or less and variable consideration under the right to invoice or wholly unsatisfied performance obligation practical expedients from this disclosure.

Disaggregation

The Company's revenue is presented on a disaggregated basis in Note 13 based on an evaluation of disclosures outside the financial statements, information regularly reviewed by the chief operating decision makers for evaluating the financial performance of operating segments and other information that is used for performance evaluation and resource allocations. This includes revenue from Communication Services, Construction, and Other revenue. Communication Services revenue is further disaggregated into business and consumer Mobility, business and consumer Fixed, Carrier Services, and Other services. Other revenue is further disaggregated into Managed Services revenue.

Receivables

The Company records an estimate of future credit losses in conjunction with revenue transactions based on the information available including historical experience and management’s expectations of future conditions. Those estimates are updated as additional information becomes available. The Company’s allowance for uncollectible accounts receivable is based on management’s assessment of the collectability of assets pooled together with similar risk characteristics.

6. USE OF ESTIMATES

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at

18

Table of Contents

the dates of the financial statements and the reported amounts of revenue and expenses during the reporting periods. The Company bases its estimates on historical experience and on various other assumptions that it believes are reasonable under the circumstances. The most significant estimates relate to revenue recognition, goodwill and long-lived intangible assets, income taxes, and contingencies. Actual results could differ significantly from those estimates.

7. FAIR VALUE MEASUREMENTS AND INVESTMENTS

In accordance with the provisions of fair value accounting, a fair value measurement assumes that a transaction to sell an asset or transfer a liability occurs in the principal market for the asset or liability or, in the absence of a principal market, the most advantageous market for the asset or liability, and defines fair value based upon an exit price model.

The fair value measurement guidance establishes a fair value hierarchy that requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The guidance describes three levels of inputs that may be used to measure fair value:

Level 1

Quoted prices in active markets for identical assets or liabilities as of the reporting date. Active markets are those in which transactions for the asset and liability occur in sufficient frequency and volume to provide pricing information on an ongoing basis. Level 1 assets and liabilities include money market funds, debt and equity securities and derivative contracts that are traded in an active exchange market.

Level 2

Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 2 assets and liabilities include debt securities with quoted prices that are traded less frequently than exchange traded instruments and derivative contracts whose value is determined using a pricing model with inputs that are observable in the market or can be derived principally from or corroborated by observable market data. This category generally includes corporate obligations and non-exchange traded derivative contracts.

Level 3

Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Level 3 assets and liabilities include financial instruments and intangible assets that have been impaired whose value is determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires significant management judgment or estimation.

Other Investments

The Company holds investments in equity securities consisting of noncontrolling investments in privately held companies. Historically, the investments are accounted for using the measurement alternative for investments without a readily determinable fair value, or fair value. The fair value investments are valued using Level 3 inputs, and the Company used the income approach to fair value the investment. The inputs consisted of a discount rate and future cash flows calculated based on the investment attributes. As of March 31, 2026, the Company’s investments were all accounted for under the measurement alternative for investments without a readily determinable value. A roll forward of the investments is set forth below (in thousands):

Redeemable Common Units and Warrants

The Company issued redeemable common units, and warrants to purchase additional common units, in a subsidiary of the Company in conjunction with its acquisition of Alaska Communications. The Company also issued redeemable common units in the parent company of the Company’s operations in the southwestern US, Alloy, in connection with its acquisition of Sacred Wind in 2022. The common units are carried at the higher of historical cost or fair value and the warrants to purchase common units are recorded at fair value in the Company’s financial statements. The instruments are redeemable at the option of the holder, beginning in November 2026 with respect to Alloy and with respect to Alaska Communications, at the earlier of its qualifying initial public offering or July 2028.

The fair value of the Alaska Communications common units was zero at both March 31, 2026 and December 31, 2025. The fair value of the warrants to purchase the Alaska Communications common units was zero at both March 31, 2026 and December 31, 2025. The Alloy common units were carried at a fair value of $15.0 million at both March 31, 2026 and December 31, 2025, which exceeded its the historical cost of $10.1 million at both March 31, 2026 and December 31, 2025. The Company calculates the fair value of the instruments using a combination of market and discounted cash flows approaches with Level 3 inputs.

Other Fair Value Disclosures

At March 31, 2026, $14.5 million of the capital expenditures spent under the Replace and Remove Program were accrued and unpaid. Amounts identified as capital are recorded as investing cash flows and amounts identified as operating are recorded as operating cash flows in the Company’s statement of cash flows. During the three months ended March 31, 2026, the Company determined that reimbursement was not probable for $9.0 million of capital expenditures incurred under the Replace and Remove Program. As a result, the Company transferred $7.0 million to assets held for sale and the remaining $2.0 million to fixed assets. Except for this $9.0 million, the Company expects to be reimbursed, within the next twelve months, for all amounts spent.

10. RETIREMENT PLANS

Multi-employer Defined Benefit Plan

Pension benefits for substantially all of the Company’s Alaska-based employees are provided through the Alaska Electrical Pension Fund (“AEPF”). The Company pays a contractual hourly amount based on employee classification or base compensation to the AEPF. As a multi-employer defined benefit plan, the accumulated benefits and plan assets are not determined for, or allocated separately to, the individual employer. This plan was not in endangered or in critical status during the plan year.

Defined Benefit Plan

The Company has noncontributory defined benefit pension and noncontributory defined medical, dental, vision, and life benefit plans for employees who meet certain eligibility criteria. The majority of the benefits under these plans are frozen and the plans no longer allow new participants to join.

The Company recorded the net periodic benefit cost identified below (in thousands):

The Company was not required to make contributions to its pension plans during the three months ended March 31, 2026 and 2025. However, the Company periodically evaluates whether to make discretionary contributions. The Company funds its postretirement benefit plans as claims are made and did not make contributions to its pension plans during the three months ended March 31, 2026 and 2025.

11.  INCOME TAXES

In July 2025, the One Big Beautiful Bill Act (“OBBBA”) was enacted in the US. The OBBBA includes significant provisions, such as the permanent extension of certain expiring provisions of the Tax Cuts and Jobs Act of 2017, modifications to the international tax framework and the restoration of favorable tax treatment for certain business provisions. The legislation has multiple effective dates, with certain provisions effective in 2025 and others implemented through 2027. The Company has reflected the impact of the enacted provisions in its financial statements for the three months ended, March 31, 2026, which were determined to be immaterial. The Company will continue to evaluate the impact of the OBBBA provisions effective in future years on the Company’s financial statements and related disclosures.

The Company’s effective tax rate for the three months ended March 31, 2026 and 2025 was (84.1%) and 1.7%, respectively.

31

Table of Contents

The Company recorded an income tax expense of $1.6 million in relation to a pretax loss of $1.9 million for the three months ended March 31, 2026. The effective tax rate for the three months ended March 31, 2026 was primarily impacted by the following items: (i) the mix of income generated among the jurisdictions in which the Company operates, (ii) the exclusion of losses in Alaska and the US Virgin Islands due to valuation allowance positions placed on certain deferred tax assets that are not expected to be realized based on the weight of positive and negative evidence, and (iii) discrete expenses including $0.3 million for interest on prior years uncertain tax positions and $0.3 million in expense associated with stock option shortfalls.

The Company recorded an income tax benefit of $0.2 million in relation to a pretax loss of $11.6 million for the three months ended March 31, 2025. The effective tax rate for the three months ended March 31, 2025 was primarily impacted by the following items: (i) the mix of income generated among the jurisdictions in which the Company operates, (ii) net expense related to valuation allowances placed on certain deferred tax assets that are not expected to be realizable based on the weight of positive and negative evidence, and (iii) discrete expenses including $0.6 million for interest on prior years uncertain tax positions and $0.5 million in expense associated with shortfalls from share-based compensation.

The Company’s effective tax rate is based upon estimated income before provision for income taxes for the year, composition of the income in different countries, and adjustments, if any, in the applicable quarterly periods for potential tax consequences, benefits and/or resolutions of tax contingencies. The Company’s consolidated tax rate will continue to be impacted by any transactional or one-time items in the future and the mix of income in any given year generated among the jurisdictions in which the Company operates. While the Company believes it has adequately provided for all tax positions, amounts asserted by taxing authorities could materially differ from the Company’s accrued positions as a result of uncertain and complex application of tax law and regulations. Additionally, the recognition and measurement of certain tax benefits include estimates and judgments by management. Accordingly, the Company could record additional provisions or benefits for US federal, state, and foreign tax matters in future periods as new information becomes available.

Redeemable Noncontrolling Interests

In connection with certain acquisitions, the Company accounts for third-party non-controlling minority investments as redeemable noncontrolling interests, which consist of both redeemable common and, in some instances, preferred units, in its consolidated financial statements.

The common units contain put options allowing the holder to sell at a future date, the common units to a subsidiary of the Company at the then fair market value. The common units participate in the earnings and losses of the subsidiaries and are allocated their applicable share of earnings and losses. After the allocation of earnings and losses, the Company estimates the fair value of the common units and records the common units at the higher of the book value or the estimated fair value of the common units.

The preferred units contain put options allowing the holder to sell at a future date, the preferred units to a subsidiary of the Company at a fixed price equal to face value of the units plus unpaid dividends. The preferred units hold a distribution preference over common units and carry a fixed dividend rate.

The put options for both the common and preferred units, if any, are nonrecourse to the Company. The put options for the Alloy common units are exercisable beginning in 2026 and the put options for the Alaska Communications common and preferred units are exercisable at the earlier of a future initial public offering of the subsidiary or July 2028.

For the three months ended March 31, 2026 and 2025, the Company allocated losses of $3.0 million and $3.6 million, respectively, to the redeemable common units representing their proportionate share of operating losses. The common units are carried at the higher of historical cost or fair value. The Alaska Communications common units were carried at a fair value of zero at both March 31, 2026 and December 31, 2025. The Alloy common units were carried at a fair value of $15.0 million, which was higher than the historical cost of $10.1 million at both March 31, 2026 and December 31, 2025.

13. SEGMENT REPORTING

Through March 31, 2026, the Company had the following two reportable and operating segments: (i) International Telecom and (ii) US Telecom.

Operating income is the segment measure of profit or loss reported to the chief operating decision maker for purposes of assessing the segments’ performance and making capital allocation decisions. The Company believes operating income is a useful measure of its operating results as it provides relevant and useful information to investors and other users of its financial data in evaluating the effectiveness of its operations and underlying business trends in a manner that is consistent with management’s evaluation of business performance. The Company’s chief operating decision maker is its Chief Executive Officer.

14. COMMITMENTS AND CONTINGENCIES

Regulatory and Litigation Matters

The Company and its subsidiaries are subject to certain regulatory and legal proceedings and other claims arising in the ordinary course of business, some of which involve claims for damages and taxes that are substantial in amount. Historically, the Company’s subsidiary, OneGY, has been subject to other long-standing litigation proceedings and disputes in Guyana that have not yet been resolved. It has been OneGY’s practice to make payments of undisputed spectrum and license fees as amounts are invoiced by the Telecommunications Authority (“TA”) and to accrue for a reasonable determination of any amounts that are disputed or not invoiced by the TA. The Company believes that,

37

Table of Contents

except for the items discussed below, for which the Company is currently unable to predict the final outcome, the disposition of matters currently pending, individually or in the aggregate, will not have a material adverse effect on the Company’s financial position or results of operations.

Since 2006, the National Frequency Management Unit (now the TA, or the “NFMU”) and OneGY have been engaged in discussions regarding the amount of and methodology for calculation of spectrum fees payable by OneGY in Guyana. Since that time, OneGY has made payments of undisputed spectrum, license and other fees when invoiced by the NFMU, and to its successor, the TA. OneGY continues to dispute in good faith the methodology used for calculation and has requested further clarification on the subject of a revised spectrum fee methodology from the TA.

OneGY has filed several lawsuits in the High Court of Guyana (the “High Court”) asserting that, despite its denials, Digicel is engaged in international bypass in violation of OneGY’s exclusive license rights, the interconnection agreement between the parties, and the laws of Guyana. Digicel filed counterclaims alleging that OneGY has violated the terms of the interconnection agreement and Guyana laws. These suits, filed in 2010 and 2012, are currently pending in the Court of Appeals in Guyana; however, as of the date of this Report, the Company cannot accurately predict when the consolidated suit will reach a court of final determination.

OneGY is also involved in several legal claims regarding its tax filings with the Guyana Revenue Authority (the “GRA”) dating back to 1991 regarding the deductibility of intercompany advisory fees as well as other tax assessments. OneGY has maintained that it has no unpaid corporation tax due to the GRA and that any liability OneGY might be found to have with respect to the disputed tax assessments would be offset in part by the amounts claimed with respect to rights ATN has pursuant to its agreement with the government of Guyana. OneGY’s position has been upheld by various High Court rulings made in its favor, and while all matters have been appealed by the GRA, as of the date of this Report, only one remained pending for determination by the High Court.

The Regulatory Authority of Bermuda (the “RA”) is the primary regulator of the Company’s operations in Bermuda.  On August 28, 2025, the RA completed a market review and determined that the Company has significant market power in certain broadband and mobile services.  In connection therewith, the RA assessed, and the Company has initiated an appeal of, a series of ex-ante remedies that include wholesale obligations, price caps, and reporting obligations in addition to the ex post competition rules that generally apply. In October 2025, the Company was able to obtain a stay of implementation of these ex-ante remedies pending the Bermuda Supreme Court’s review of its appeal of the RA’s market review determination. The ex-ante remedies are burdensome and, if implemented, will require financial, operational, legal and regulatory resources to be allocated to ensure compliance.

With respect to all of the foregoing unresolved matters, the Company believes that some adverse outcome is probable and has accordingly accrued $17.4 million as of March 31, 2026 for these and other potential liabilities arising in various claims, legal actions and regulatory proceedings arising in the ordinary course of business. The Company also faces contingencies that are reasonably possible to occur that cannot currently be estimated. It is the Company’s policy to expense costs associated with loss contingencies, including any related legal fees, as they are incurred.

Item 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following Management's Discussion and Analysis of Financial Condition and Results of Operations (this “MD&A”) is intended to help the reader understand the Company, our operations and our present business environment. This MD&A is provided as a supplement to — and should be read in conjunction with — our MD&A for fiscal year 2025, which can be found in Part II, Item 7 of our Annual Report on Form 10-K for the year ended December 31, 2025.

In addition, the following discussion and analysis of financial condition and results of operations are based upon our Consolidated Financial Statements and should be read in conjunction with these statements and notes thereto.

Overview

We are a leading provider of digital infrastructure and communications services with a strategic focus on rural and remote markets in the US, and internationally, including Bermuda and the Caribbean region.

We have developed significant operational capabilities and resources that enhance the performance of our local market operations. Our operating subsidiaries benefit from this shared expertise, which allows them to deliver improved service quality and achieve greater economies of scale than would typically be possible in the smaller markets we serve. We provide centralized management, technical, financial, regulatory, and marketing support to these operating subsidiaries and typically receive a management fee based on a percentage of their revenues. The intercompany fees are eliminated in our consolidated financial results.

We use the cash generated from our operations to repay debt and increase liquidity, reinvest our network and service operations, fund capital expenditures, return value to stockholders through dividends or share repurchases, and to pursue strategic transactions. We continuously evaluate both domestic and international opportunities that align with our long-term goal of generating sustained excess operating cash flows.

For additional information regarding our reportable segments and geographic distribution of revenues and assets, please refer to Notes 1 and 13 of the Consolidated Financial Statements included in this Report.

As of March 31, 2026, we offered the following services to our customers:

Fixed Services. We provide fixed data and voice telecommunications services to business and consumer customers, including high-speed broadband and enterprise data solutions. In select markets, fixed services also include video offerings and revenue derived from support under certain government programs.
Carrier Services. We offer infrastructure services to other telecommunications providers, including the leasing of critical network infrastructure such as towers and transport facilities, wholesale roaming, site maintenance and international long-distance services.
Mobility Services. We offer mobile communications services over our wireless networks, including voice, messaging and data services along with related equipment, such as handsets, to both business and consumer customers.
Managed Services. We deliver information technology solutions, including network management, application support and infrastructure services to complement our fixed telecommunications services in our existing markets for the purpose of supporting both enterprise and residential users.

39

Table of Contents

Through March 31, 2026, we identified two operating segments to manage and review our operations, as well as to support investor presentations of our results. These operating segments are as follows:

International Telecom.  In our international markets, we offer fixed, carrier, mobility and managed services to customers in Bermuda, the Cayman Islands, Guyana and the US Virgin Islands.
US Telecom.  In the US, we offer fixed, carrier, and managed services to customers in Alaska and the western US.

(1)During 2025, we continued to unify branding across our networks, and we now sell Fixed and Mobility Services under the “One Communications” brand in Bermuda, Guyana and the US Virgin Islands. We refer to our business in Guyana as “OneGY” and we refer to our business in the US Virgin Islands as “OneVI” throughout this Report.

Tower Portfolio Transaction

On February 11, 2026, through certain Commnet subsidiaries, we entered into a Purchase and Sale Agreement (the “Transaction Agreement”) with EIP Holdings IV, LLC, an affiliate of Everest Infrastructure Partners, Inc. (“Everest”), to sell approximately 214 tower portfolio sites (representing the substantial majority of our Commnet tower portfolio and operations (the “Tower Portfolio”) to Everest for up to $297 million in cash consideration, subject to certain adjustments and prorations (the “Tower Portfolio Transaction”).

The Tower Portfolio Transaction may be completed in one or more closings. The Transaction Agreement sets forth certain conditions that must be satisfied prior to the conveyance of tower sites at a closing. During the period between signing and the initial closing, the parties will determine which tower sites within the Tower Portfolio have satisfied such conditions and are ready to be conveyed at the initial closing, which sites have not yet satisfied all such conditions but for which Everest is prepared to assume management pending satisfaction of such conditions, and which sites are not yet constructed or are subject to other conditions that will continue to be managed by us until such conditions are satisfied.

At the initial closing, we will enter into, among other ancillary agreements, (i) a management agreement for

40

Table of Contents

certain sites, (ii) master lease agreements, pursuant to which we will lease the requisite ground, tower, or other space of the conveyed tower site for our continued use, and (iii) a preferred backhaul agreement whereby we will become the preferred backhaul provider with respect to the conveyed tower sites.

The Transaction Agreement contains customary representations, warranties, covenants, and indemnities by each of the parties, and requires the receipt of certain consents and approvals prior to a closing. The waiting period required under the Hart-Scott Rodino Act of 1976 with respect to the Tower Portfolio Transaction expired in early March 2026. If the Transaction Agreement is terminated under certain circumstances that are not our fault, we will receive a termination fee equal to approximately $14.9 million.

We continue to expect the initial closing of the Tower Portfolio Transaction to occur in the second quarter of 2026 generating gross proceeds of approximately $250 million to $270 million. Subsequent closings, totaling approximately $27 million to $47 million, are anticipated to occur over the twelve months following the initial closing, subject to the achievement of specified construction and operational milestones at designated sites within the Tower Portfolio.

We now currently anticipate that approximately 45-55% of the amount of proceeds to be received at the initial closing will be subject to post-closing resolution, due to delays in obtaining ground lease assigning consents from government and tribal agencies, as well as other conditions being satisfied with respect to such sites.

Universal Service Fund and Other Domestic Funding Programs

In general, all telecommunications providers are obligated to contribute to the Universal Service Fund (“USF”), which is used to promote the availability of qualifying telecommunications and broadband service to low-income households, households located in rural and high-cost areas, and to schools, libraries, and rural health care providers. We contribute to the USF and also receive various forms of USF support. We are subject to audit by the Universal Service Administrative Company with respect to our federal contributions and our receipts of universal service funding. To our knowledge, as of the date of this Report, we were in compliance with, in all material respects, applicable federal and state USF assessment and support requirements.

USF High-Cost Support. The Federal Communications Commission’s (“FCC”) high-cost USF (or alternatives to former high-cost USF) mechanisms promote the deployment and operation of voice and broadband networks in areas where high costs would otherwise undermine the availability of service to consumers, including in rural, insular, and remote areas. High-cost support mechanisms generally include explicit conditions to deploy broadband to new locations and provide service meeting specified standards. We receive several forms of high-cost support, including but not limited to, as follows:

We receive federal USF support under the Alaska Connect Fund (“ACF”). Beginning January 1, 2025, we began receiving $25.6 million per year and expect such annual funding to continue until December 31, 2028. Beginning in 2029 and continuing through 2034, the amount of ACF support we receive will be determined by the FCC staff taking into consideration broadband deployment funded through the Broadband Equity Access and Deployment Program;
As part of the Enhanced Alternative Connect America Model (“E-ACAM”) funding available to our operations in the western US, we are estimated to receive approximately $9 million annually through 2029 before gradually increasing to $13 million annually in 2038. This funding is subject to a requirement to deploy voice and broadband service at speeds of 100/20 Mbps to all required locations by the end of calendar year 2028;
We expect to receive approximately $8 million per year in CAF II support in the rural southwest US until July 2028;
We received approximately $5.5 million annually in the US Virgin Islands through December 31, 2025. In September 2025, we requested that the FCC extend such support for at least one additional year. As of the

41

Table of Contents

date of this Report, the FCC had not yet acted on this request and, as a result, the Company is currently not receiving this support. If the FCC grants our request, it may or may not extend our support on a retroactive basis from December 31, 2025; and
We receive state USF support in Alaska of approximately $2.5 million annually.

As of March 31, 2026, we were in compliance in all material respects with requirements associated with such funding. If we fail to meet these obligations or require substantial additional capital expenditures to meet the obligations in a timely manner, our revenue, results of operations and liquidity may be materially adversely impacted.

Construction Grants

We have also been awarded construction grants to build network connectivity for eligible communities. The funding of these grants, used to reimburse us for our construction costs, is generally distributed after we incur reimbursable costs. Once these projects are constructed, we are obligated to provide service to the participants. We expect to meet all requirements associated with these grants. As of March 31, 2026, we were awarded $100.9 million of construction grants that are pending completion.

During the three months ended March 31, 2026, we disbursed capital expenditures of $5.1 million under these programs and received reimbursement of $5.1 million. These cash flows are classified as investing activities in our statement of cash flows.

In addition, we partner with tribal governments to obtain grants under various government grant programs including, but not limited to, the Tribal Broadband Connectivity Program (“TBCP”) and the Rural Development Broadband ReConnect Program (“ReConnect”). These programs are administered by US government agencies to deploy broadband connectivity in certain underserved areas. We were identified as a sub recipient of grants under these programs totaling $239 million as of March 31, 2026. Through March 31, 2026, we received $37.7 million of funding under these programs and spent $40.4 million on construction obligations. These amounts are recorded as operating cash flows in the Company’s statement of cash flows.

Replace and Remove Program

In July 2022, we were approved to participate in the FCC’s Secure and Trusted Communications Network Reimbursement Program (the “Replace and Remove Program”), designed to reimburse providers of advanced communications services for reasonable costs incurred in the required removal, replacement, and disposal of communications equipment and services in their networks that has been deemed to pose a national security risk. Pursuant to the Replace and Remove Program, our eligible subsidiaries were initially allocated up to approximately $207 million to replace, remove and securely destroy such communications equipment and services in our networks in the western US and in the US Virgin Islands; however, in December 2024, this program was fully funded for an increased allocation to the Company of an aggregate amount of approximately $517 million. The Replace and Remove Program requires each of our participating subsidiaries to complete the project no later than a specified deadline, which was recently extended through early November 2026.

As of March 31, 2026, we had incurred total expenditures of $233.1 million related to this project, of which $8.4 million were incurred in 2026. Of these total expenditures, $192.2 million was classified as capital.

As of March 31, 2026, $14.5 million of capital expenditures was accrued and unpaid under the Replace and Remove Program. During the three months ended March 31, 2026, we received $9.3 million of reimbursement under the program, of which $1.1 million was classified as operating cash inflows and $8.2 million was classified as investing cash inflows in our statement of cash flows. During the three months ended March 31, 2026, we determined that reimbursement was not probable for $9.0 million of capital expenditures incurred under the Replace and Remove Program. As a result, we transferred $7.0 million to assets held for sale and the remaining $2.0 million to fixed assets. Except for this $9.0 million, the Company expects to be reimbursed, within the next twelve months, for all amounts spent.

Selected Segment Financial Information

Through March 31, 2026, the Company had the following two reportable and operating segments: (i) International Telecom and (ii) US Telecom.

Operating income is the segment measure of profit or loss reported to the chief operating decision maker for purposes of assessing the segments' performance and making capital allocation decisions. We believe operating income is a useful measure of our operating results as it provides relevant and useful information to investors and other users of our financial data in evaluating the effectiveness of our operations and underlying business trends in a manner that is consistent with management's evaluation of business performance. Our chief operating decision maker is our Chief Executive Officer.

Table of Contents

A comparison of our segment results for the three months ended March 31, 2026 and 2025 is as follows:

International Telecom. Revenues within our International Telecom segment increased $1.6 million, or 1.7%, to $96.1 million from $94.5 million for the three months ended March 31, 2026 and 2025, respectively, primarily due to an increase in revenues from ancillary services, increases in Mobility Services revenues as a result of an increase in subscribers and increases in Carrier Services revenue as a result of increased roaming.  These increases were partially offset by a reduction in revenue received from the FCC’s High-Cost Support Program in the US Virgin Islands, which was terminated on December 31, 2025.

Operating expenses within our International Telecom segment decreased by $2.9 million, or 3.6%, to $76.8 million from $79.7 million for the three months ended March 31, 2026 and 2025, respectively.  The net decrease was primarily the result of certain cost savings initiatives, including reorganizations and reductions in force, that were implemented in the current and previous periods as well as a decrease in depreciation and amortization expenses as a result of a reduction in capital expenditures in recent periods.

As a result, our International Telecom segment’s operating income increased $4.4 million, or 29.7%, to $19.2 million from $14.8 million for the three months ended March 31, 2026 and 2025, respectively.

US Telecom.  Revenue within our US Telecom segment increased by $1.4 million, or 1.7%, to $86.2 million from $84.8 million for the three months ended March 31, 2026 and 2025, respectively, primarily as a result of a $2.7 million increase in Carrier Services revenue due to the transition of legacy roaming arrangements to carrier service management contracts. Partially offsetting this increase was a decline in the construction revenue of $1.0 million as a result of a decrease in the number of sites completed in 2026 as compared to 2025.

Operating expenses within our US Telecom segment decreased $2.8 million, or 3.2%, to $84.4 million from $87.2 million for the three months ended March 31, 2026 and 2025, respectively, as a result of the impact of certain cost savings initiatives, including the reorganizations and reductions in force, that were implemented in the current and previous periods.  

As a result of the above, our US Telecom segment’s operating income increased to income of $1.7 million from a loss of $2.4 million for the three months ended March 31, 2026 and 2025, respectively.

Communications Services Revenue

Mobility Services Revenue. Our Mobility Services revenue consists of revenue generated within our International Telecom segment by providing business and retail mobile voice and data services over our wireless networks, as well as through the sale and repair services of related equipment, such as handsets and other accessories, to our subscribers.

Mobility Services revenue increased by $0.3 million, or 1.1%, to $26.4 million for the three months ended March 31, 2026 from $26.1 million for the three months ended March 31, 2025 as result of an increase in subscribers.

Mobility Services revenue within our International Telecom may continue to increase as a result of our continued network upgrades, marketing efforts and conversion of our current subscriber base to higher margin prepaid and postpaid plans. Such increases may, however, be negatively impacted by increased competition and regulatory changes.

Fixed Services Revenue. Fixed Services revenue is primarily generated by broadband, voice, and video service revenues provided to retail and business customers over our wireline networks. Fixed Services revenue within our US Telecom segment also includes awards from the CAF II program, the E-ACAM program, and the Alaska USF. Within our International Telecom segment, Fixed Services revenue includes funding, through December 31, 2025, under the FCC’s High-Cost Program in the US Virgin Islands.

Fixed Services revenue decreased by $0.3 million, or 0.3%, to $112.7 million from $113.0 million for the three months ended March 31, 2026 and 2025, respectively. This decrease primarily pertained to a decrease in Fixed Services revenue from business customers and consisted of the following:

International Telecom. Within our International Telecom segment, Fixed Services revenue decreased by $0.8 million, or 1.3%, to $60.6 million from $61.4 million for the three months ended March 31, 2026 and 2025, respectively. This decrease was primarily a result of the FCC’s High-Cost Support Program in the US Virgin Islands being terminated on December 31, 2025. This decrease was partially offset by an increase in subscribers.
US Telecom. Fixed Services revenue within our US Telecom segment increased by $0.4 million, or 0.8%, to $52.1 million from $51.7 million for the three months ended March 31, 2026 and 2025, respectively. This increase was primarily the result of increased revenue from the FCC’s High-Cost Program support in the southwest US.

Fixed Services revenue within our International Telecom segment may continue to increase as we expect the popularity of video and audio streaming, the demand for cloud services and smart home, business and city solutions to increase the demand for broadband and other data services from consumers, businesses and governments. However, such increases may be offset by a decrease in demand for our legacy services due to subscribers using alternative methods to receive video and audio content.

Within our US Telecom segment, we expect Fixed Services revenue to increase moderately as a result of an increase in government grants and our deployment of fiber and fiber-fed broadband access to both consumers and businesses.

Carrier Services Revenue. Carrier Services revenue is generated by both our International Telecom and US Telecom segments. Within our International Telecom segment, Carrier Services revenue includes international long-distance services, roaming revenues generated by other carriers’ customers roaming into our retail markets, transport services and access services provided to other telecommunications carriers. Within our US Telecom segment, Carrier Services revenue includes services provided under the Network Build and Maintenance Agreement with AT&T Mobility, LLC (“AT&T”) that we subsequently amended in May 2026 (the “FirstNet Agreement”) and Carrier Managed

48

Table of Contents

Services Master Agreement that we subsequently amended in May 2026 (the “Verizon CMS Agreement”) with Cellco Partnership d/b/a Verizon Wireless (“Verizon”), wholesale roaming revenues, the provision of network switching services, tower lease revenue and other services provided to other carriers.

Carrier Services revenue increased by $3.0 million, or 9.1%, to $36.1 million from $33.1 million for the three months ended March 31, 2026 and 2025, respectively. The increase within our segments consisted of the following:

International Telecom. Within our International Telecom segment, Carrier Services revenue increased by $0.3 million, or 7.7%, to $4.2 million, from $3.9 million for the three months ended March 31, 2026 and 2025, respectively, primarily as a result of an increase in roaming revenues in some of our international markets.

US Telecom. Carrier Services revenue within our US Telecom segment increased by $2.7 million, or 9.2%, to $31.9 million from $29.2 million, for the three months ended March 31, 2026 and 2025, respectively. This increase was primarily the result of the transition of legacy roaming arrangements to carrier service management contracts.

Within our International Telecom segment, Carrier Services revenue may continue to increase if international travel in our market grows.

Within our US Telecom segment, Carrier Services revenue is expected to decline upon the completion of the Tower Portfolio Transaction.

Other Communications Services Revenue. Other Communications Services revenue includes project-related revenue generated within both our International and US Telecom segments and ancillary services that the operations within our International Telecom segment provide to its retail subscribers. Other Communications Services revenue increased $1.5 million, or 83.3%, to $3.3 million from $1.8 million for the three months ended March 31, 2026 and 2025, respectively, as a result of an increase in revenue from ancillary services in our International Telecom segment.

Other Communication Services revenue may increase in future periods as the demand for ancillary services increase.

Construction Revenue

Construction revenue represents revenue generated within our US Telecom segment for the construction of network cell sites related to the FirstNet Agreement. As of December 31, 2025, we had substantially completed the build of AT&T’s network under the FirstNet Agreement. As a result, we did not record any construction revenue during the three months ended March 31, 2026. During the three months ended March 31, 2025, we recorded construction revenue of $1.0 million.

Other Revenue

Managed Services Revenue. Managed Services revenue is generated within both our International and US Telecom segments and includes network, application, infrastructure, and hosting services.

Managed Services revenue decreased by $0.4 million, or 9.5%, to $3.8 million from $4.2 million for the three months ended March 31, 2026 and 2025, respectively. The net decrease consisted of a decrease within our US Telecom segment that was partially offset by an increase within our International Telcom segment, as detailed below:

US Telecom. Within our US Telecom segment, Managed Services revenue decreased $0.8 million, or 28.6%, to $2.0 million from $2.8 million for the three months ended March 31, 2026 and 2025, respectively.

Managed Services revenue may increase in both our US and International Telecom segments as a result of our efforts to sell certain Managed Services solutions to primarily business customers in all of our markets.

Operating Expenses

Cost of communication services and other. Cost of communication services and other are charges that we incur for voice and data transport circuits, internet capacity, video programming costs, access fees we pay to terminate our calls, telecommunication spectrum fees and direct costs associated within our managed services businesses. These costs also include expenses associated with developing, operating, upgrading and supporting our telecommunications networks, including the salaries and benefits paid to employees directly involved in the development and operation of those businesses, as well as credit loss allowances and the cost of handsets and customer resale equipment incurred by our retail businesses.

Cost of communication services and other decreased by $0.8 million, or 1.0%, to $77.4 million from $78.2 million for the three months ended March 31, 2026 and 2025, respectively. The net decrease in cost of communication services and other, within our segments, consisted of the following:

International Telecom. Within our International Telecom segment, cost of communication services and other decreased by $1.4 million, or 4.0%, to $33.6 million from $35.0 million, for the three months ended March 31, 2026 and 2025, respectively. This decrease was the result of the impact of cost savings initiatives, including reorganizations and reductions in force, that were implemented in the current and previous periods.

US Telecom. Cost of communication services and other within our US Telecom segment increased by $0.5 million, or 1.2%, to $43.8 million from $43.3 million for the three months ended March 31, 2026 and 2025, respectively. Such increase was the result of increased tower site expenses partially offset by the impact of certain cost savings initiatives, including reorganizations and reductions in force, that were implemented in the current and previous periods.

Cost of communication services in our International Telecom segment may decrease as a result of the ongoing cost reduction initiatives that commenced in previous periods, but such decrease may be partially offset by future inflationary pressure.

We expect that the cost of communication services, within our US Telecom segment, will increase upon the completion of the Tower Portfolio Transaction and may also increase as a result of future inflationary pressure. However, the impact of our cost reduction initiatives, that commenced in previous periods, may partially offset those increases.

Cost of construction revenue. Cost of construction revenue includes the expenses incurred in connection with the construction of and the delivery to AT&T of cell sites in accordance with our FirstNet Agreement. As of December 31, 2025, we had substantially completed the build of AT&T’s network under the FirstNet Agreement. As a result, we did not record any cost of construction revenue during the three months ended March 31, 2026. During the three months ended March 31, 2025, we recorded cost of construction revenue of $1.5 million.

Selling, general and administrative expenses. Selling, general and administrative expenses include salaries and benefits we pay to sales personnel, customer service expenses and the costs associated with the development and implementation of our promotional and marketing campaigns. Selling, general and administrative expenses also include salaries, benefits and related costs for general corporate functions including executive management, finance and administration, legal and regulatory, facilities, information technology and human resources as well as internal costs associated with our performance of due-diligence and integration related costs associated with acquisition activities.

Selling, general and administrative expenses increased by $1.0 million, or 1.8%, to $56.2 million from $55.2 million for the three months ended March 31, 2026 and 2025, respectively. The net increase in selling, general and administrative expenses, within our segments, consisted of the following:

International Telecom. Within our International Telecom segment, our selling, general and administrative expenses increased by $1.0 million, or 3.7%, to $28.1 million from $27.1 million for the three months ended March 31, 2026 and 2025, respectively, as a result of an increase in marketing and personnel costs in certain markets that was partially offset by the impact of certain cost containment initiatives, including the reorganizations and reductions in force, that were implemented in the current and previous periods.
US Telecom. Selling, general and administrative expenses increased within our US Telecom segment by $0.4 million, or 1.8%, to $22.9 million from $22.5 million, for the three months ended March 31, 2026 and 2025, respectively, as a result of an increase in personnel costs partially offset by the impact of certain cost containment initiatives, including the reorganizations and reductions in force that were implemented in the current and previous periods.
Corporate Overhead. Selling, general and administrative expenses within our corporate overhead decreased by $0.4 million, or 7.1%, to $5.2 million from $5.6 million, for the three months ended March 31, 2026 and 2025, respectively, as a result of a decrease in certain professional fees.

Selling, general and administrative expenses in all our segments may decrease as a result of the ongoing cost reduction initiatives that commenced in previous periods, but such decrease may be partially offset by future inflationary pressure.

Stock-based compensation. Stock-based compensation represents a non-cash expense related to the amortization of grants of equity awards to employees and directors.

Stock-based compensation for both the three months ended March 31, 2026 and 2025 was $1.9 million.

Transaction-related charges.  Transaction-related charges include the external costs, such as legal, tax, accounting and consulting fees directly associated with acquisition and disposition-related activities and certain financing activities that are expensed as incurred. Transaction-related charges do not include employee salary and travel-related expenses incurred in connection with acquisitions or dispositions or any integration-related costs.

We incurred $0.8 million and $1.4 million of transaction-related charges during the three months ended March 31, 2026 and 2025, respectively. Such decrease was the result of the timing of our transaction-related charges.

Restructuring and reorganization expenses. In our efforts to advance our cost management actions to drive higher operating efficiencies and margins, we incurred certain restructuring and reorganization expenses, primarily reductions in force, totaling $0.7 million, $0.2 million and $0.8 million within our International Telecom segment, US Telecom segment and Corporate and Other segment, respectively, during the three months ended March 31, 2026.

We incurred restructuring and reorganization expenses of $1.5 million, $0.1 million and $0.2 million within our International Telecom segment, US Telecom segment and Corporate and Other segment, respectively, during the three months ended March 31, 2025.

Increase and decreases in restructuring and reorganization expenses within each segment are a result of the timing and magnitude of our reductions in force.

 Depreciation and amortization expenses. Depreciation and amortization expenses represent the depreciation and amortization charges we record on our property and equipment.

Depreciation and amortization expenses decreased by $3.3 million, or 9.6%, to $31.2 million from $34.5 million for the three months ended March 31, 2026 and 2025, respectively. The net decrease in depreciation and amortization expenses, within our segments, consisted primarily of the following:

International Telecom. Depreciation and amortization expenses decreased within our International Telecom segment by $1.8 million, or 11.7%, to $13.6 million from $15.4 million, for the three months ended March 31, 2026 and 2025, respectively. The decrease was the result of this segment’s reduction in capital expenditures in recent periods and certain assets becoming fully depreciated in recent periods.

US Telecom. Depreciation and amortization expenses decreased within our US Telecom segment by $1.4 million, or 7.7%, to $16.9 million from $18.3 million, for the three months ended March 31, 2026 and 2025, respectively. The decrease was the result of this segment’s reduction in capital expenditures in recent periods, certain assets becoming fully depreciated in recent periods, and the conclusion of the recording of depreciation expense related to assets that are held for sale in connection with the Tower Portfolio Transaction.
Corporate Overhead. Depreciation and amortization expenses decreased within our corporate overhead to $0.7 million from $0.9 million, for the three months ended March 31, 2026 and 2025, respectively, primarily as a result of additional assets becoming fully depreciated in recent periods.

We expect depreciation and amortization expenses to continue to decrease as a result of an expected decline in capital expenditures and as a result of some of our previously acquired assets becoming fully depreciated.

Amortization of intangibles from acquisitions. Amortization of intangibles from acquisitions include the amortization of customer relationships and trade names related to our completed acquisitions.

Amortization of intangibles from acquisitions decreased by $0.7 million to $0.5 million from $1.2 million for the three months ended March 31, 2026 and 2025, respectively, as a result of certain assets being fully amortized in previous periods.

We expect that amortization of intangibles from acquisitions will continue to decrease in future periods as such assets continue to amortize.

Loss on disposition of assets, transfers and contingent consideration. During both the three months ended March 31, 2026 and 2025, we recorded a net loss on the disposition of assets and transfers of $0.8 million. Of this net loss, $0.4 million was recognized within both our International and US Telecom segments for the three-month period ended March 31, 2026, and $0.3 million and $0.5 million was recognized within our International and US Telecom segments, respectively, for the three-month period ended March 31, 2025

Interest income. Interest income represents interest earned on our cash, cash equivalents, restricted cash and short-term investment balances. Interest income was $0.1 million and $0.3 million for the three months ended March 31, 2026 and 2025, respectively.

Interest expense.   We incur interest expense on the 2023 CoBank Credit Facility, the 2024 Alaska Credit Facilities, the FirstNet Receivables Credit Facility, the IDB Credit Facilities, the Sacred Wind Term Debt and the OneVI

52

Table of Contents

Debt (each as defined below). In addition, interest expense includes commitment fees, letter of credit fees and the amortization of debt issuance costs.

Interest expense decreased to $10.5 million from $12.0 million for the three months ended March 31, 2026 and 2025, respectively, as a result of reduced interest rates, which were impacted by certain interest rate swap agreements, on our borrowings.

Interest Expense. Interest expense in future periods may decline upon the completion of the Tower Portfolio Transaction if the proceeds from that transaction are used to reduce our debt balances.

Other expense. For the three months ended March 31, 2026, other expense was $3.2 million of expense primarily related to a $2.6 million loss from our noncontrolling investments and $0.4 million in losses on foreign currency transactions.

For the three months ended March 31, 2025, other expense was $2.6 million of expense primarily related to a non-operating employee-related matter and $0.4 million in losses on foreign currency transactions.

Income taxes. Our effective tax rates for the three months ended March 31, 2026 and 2025 were (84.1)% and 1.7%, respectively.

We recorded an income tax expense of $1.6 million in relation to a pretax loss of $1.9 million for the three months ended March 31, 2026. The effective tax rate for the three months ended March 31, 2026 was primarily impacted by the following items: (i) the mix of income generated among the jurisdictions in which we operate, (ii) the exclusion of losses in Alaska and the US Virgin Islands due to valuation allowance positions placed on certain deferred tax assets that are not expected to be realized based on the weight of positive and negative evidence, and (iii) discrete expenses including $0.3 million for interest on prior years uncertain tax positions and $0.3 million expense associated with stock option shortfalls.

We recorded an income tax benefit of $0.2 million in relation to a pretax loss of $11.6 million for the three months ended March 31, 2025. The effective tax rate for the three months ended March 31, 2025 was primarily impacted by the following items: (i) the mix of income generated among the jurisdictions in which we operate, (ii) net expense related to valuation allowances placed on certain deferred tax assets that are not expected to be realized based on the weight of positive and negative evidence, and (iii) discrete expenses including $0.6 million for interest on prior years uncertain tax positions and $0.5 million expense associated with stock option shortfalls.

Our effective tax rate is based upon estimated income before provision for income taxes for the year, composition of the income in different countries, and adjustments, if any, in the applicable quarterly periods for potential tax consequences, benefits and/or resolutions of tax contingencies. Our consolidated tax rate will continue to be impacted by any transactional or one-time items in the future and the mix of income in any given year generated among the jurisdictions in which we operate. While we believe we have adequately provided for all tax positions, amounts asserted by taxing authorities could materially differ from our accrued positions as a result of uncertain and complex application of tax law and regulations. Additionally, the recognition and measurement of certain tax benefits include estimates and judgments by management. Accordingly, we could record additional provisions or benefits for US federal, state, and foreign tax matters in future periods as new information becomes available.

Net loss attributable to noncontrolling interests, net of tax.  Net loss attributable to noncontrolling interests, net of tax reflected an allocation of $0.7 million and $2.5 million of losses generated by our less than wholly owned subsidiaries for the three months ended March 31, 2026 and 2025, respectively. Changes in net loss attributable to noncontrolling interests, net of tax, within our segments, consisted of the following:

International Telecom. Within our International Telecom segment, net income attributable to noncontrolling interests, net of tax increased by $1.1 million, or 73.3%, to an allocation of $2.6 million of

53

Table of Contents

income from an allocation of $1.5 million of income for the three months ended March 31, 2026 and 2025, respectively. The decrease was the result of increased profitability at certain less than wholly owned subsidiaries.

US Telecom. Within our US Telecom segment, net loss attributable to noncontrolling interests, net of tax decreased by $0.6 million, or 15.4%, to an allocation of losses of $3.3 million from an allocation of losses of $3.9 million for the three months ended March 31, 2026 and 2025. The decrease was a result of decreased losses at our less than wholly owned subsidiaries within this segment.

Net loss attributable to ATN International, Inc. stockholders.  Net loss attributable to ATN International, Inc. stockholders was $2.8 million for the three months ended March 31, 2026 as compared to $8.9 million for the three months ended March 31, 2025.

On a per diluted share basis, net loss was $0.29 per diluted share for the three months ended March 31, 2026 as compared to $0.69 per diluted share for the three months ended March 31, 2025. Such per share amounts were negatively impacted by accrued preferred dividends of $1.6 million and $1.5 million for the three months ended March 31, 2026 and 2025, respectively.

Regulatory and Tax Issues

We are involved in a number of regulatory and tax proceedings. A material and adverse outcome in one or more of these proceedings could have a material adverse impact on our financial condition and future operations. For discussion of ongoing proceedings, see Note 14 to the Consolidated Financial Statements in this Report

One Big Beautiful Bill Act

In July 2025, the One Big Beautiful Bill Act (“OBBBA”) was enacted in the US. The OBBBA includes significant provisions, such as the permanent extension of certain expiring provisions of the Tax Cuts and Jobs Act of 2017, modifications to the international tax framework and the restoration of favorable tax treatment for certain business provisions. The legislation has multiple effective dates, with certain provisions effective in 2025 and others implemented through 2027. The Company reflected the impact of the enacted provisions in its financial statements for the three months ended, March 31, 2026, which were determined to be immaterial. The Company will continue to evaluate the impact of the OBBBA provisions effective in future years on the Company’s financial statements and related disclosures.

Liquidity and Capital Resources

Historically, we have met our operational liquidity needs and have funded our capital expenditures and acquisitions through a combination of cash-on-hand, internally generated funds, borrowings under our credit facilities, proceeds from dispositions, and seller financings. We believe our current cash, cash equivalents, short term investments and availability under our current credit facilities will be sufficient to meet our cash needs for at least the next twelve months for working capital and capital expenditure requirements. 

Total liquidity.  As of March 31, 2026, we had approximately $123.5 million in cash, cash equivalents, and restricted cash. Of this amount, $73.9 million was held by our foreign subsidiaries and is indefinitely invested outside the US. In addition, we had approximately $570.2 million of debt, net of unamortized deferred financing costs as of March 31, 2026. How and when we deploy our balance sheet capacity, including the availability under our various credit facilities (as further described below), will figure prominently in our longer-term growth prospects and stockholder returns.

Uses of Cash

Acquisitions and investments.  We have historically funded our acquisitions with a combination of cash-on-hand, borrowings under our credit facilities as well as equity investor and seller financings. 

We continue to explore opportunities to expand our telecommunications business or acquire new businesses in the US, the Caribbean and elsewhere. Such acquisitions may require external financing. While there can be no assurance as to whether, when or on what terms we will be able to acquire any such businesses or make such investments, such acquisitions may be completed through the issuance of shares of our capital stock, payment of cash or incurrence of additional debt. From time to time, we may raise capital ahead of any definitive use of proceeds to allow us to move more quickly and opportunistically if an attractive investment materializes.

Cash used in investing activities. Cash used in investing activities decreased by $4.3 million to $20.8 million from $25.1 million for the three months ended March 31, 2026 and 2025, respectively. This year-over-year decrease in cash used in investing activities was primarily the result of a decrease in cash used for reimbursable capital expenditures of $8.9 million net of a $4.0 million decrease in cash inflows related to the reimbursement of capital expenditures under certain government programs. This decrease was partially offset by an increase in non-reimbursable capital expenditures of $0.2 million.

Cash used in financing activities. Cash used by financing activities decreased to $2.7 million from $2.8 million for the three months ended March 31, 2026 and 2025, respectively. The decrease in cash used by financing activities of $0.1 million was primarily the result of a $1.1 million increase in cash used to repurchase our common stock from employees to satisfy certain tax withholding obligations and a $0.6 million increase in cash used for dividends paid to our stockholders. Such increases were offset by an increase in cash provided by funds payable and due to customers of $1.7 million.

Working Capital.  We have funded our working capital needs through a combination of internally generated funds and borrowings under our credit facilities. Pursuant to the FirstNet Agreement, AT&T has the option to repay construction costs, with interest, over an eight-year period. To fund the working capital needs created by AT&T’s option to extend its payment terms, we completed the Receivables Credit Facility, as discussed below, on March 26, 2020.

For the three months ended March 31, 2026, we spent approximately $21.0 million for capital expenditures and $13.5 million for capital expenditures that are reimbursable under certain government programs. For the three months ended March 31, 2025, we spent approximately $20.8 million for capital expenditures and $22.4 million for capital expenditures that are reimbursable under certain government programs. The following shows our capital expenditures, by operating segment, for these periods (in thousands):

We are continuing to invest in our telecommunication networks along with our operating and business support systems in many of our markets. For the year ending December 31, 2026, such investments are expected to total approximately $105 million to $115 million of non-reimbursable capital expenditures and will primarily relate to network expansion and upgrades which are expected to further drive subscriber and revenue growth in future periods.

Income taxes. We have historically used cash-on-hand to make payments for income taxes. Our policy is to allocate capital where we believe we will get the best returns and to date has been to indefinitely reinvest the undistributed earnings of our foreign subsidiaries. As we continue to reinvest our remaining foreign earnings, no additional provision for income taxes has been made on the accumulated earnings of foreign subsidiaries.

Dividends.   For the three months ended March 31, 2026, our Board of Directors declared $4.2 million of dividends to our stockholders which included a $0.275 per share dividend declared on March 18, 2026 and paid on April 10, 2026. We have declared quarterly dividends since the fourth quarter of 1998.

Stock Repurchase Plan. Our Board of Directors has authorized the repurchase of up to $25.0 million of our common stock, from time to time, on the open market or in privately negotiated transactions (the “2023 Repurchase Plan”). We did not repurchase any of our common stock under the 2023 Repurchase Plan during either the three months ended March 31, 2026 or 2025. As of March 31, 2026, we had $15.0 million available to repurchase shares of our common stock under the 2023 Repurchase Plan.

Sources of Cash

Cash provided by operations.  Cash provided by operating activities was $29.8 million for the three months ended March 31, 2026 as compared to $35.9 million for the three months ended March 31, 2025.  The decrease of $6.1 million was primarily related to a decrease in our net loss of $8.4 million offset by increased working capital requirements.  

2023 CoBank Credit Facility

On July 13, 2023, we, along with certain of our subsidiaries as guarantors, entered into a Credit Agreement (as may be amended from time to time, the “2023 CoBank Credit Agreement”) with CoBank, ACB (“CoBank”) and a syndicate of other lenders (the “2023 CoBank Credit Facility”). On July 10, 2024, we amended the 2023 CoBank Credit Agreement to add certain subsidiaries as guarantors and to provide further flexibility in order to accept certain grant and government program obligations.

The 2023 CoBank Credit Facility provides for a five-year $170 million revolving credit facility (the “2023 CoBank Revolving Loan”) and a six-year $130 million term loan facility (the “2023 CoBank Term Loan”). We may use (i) up to $25 million under the 2023 CoBank Revolving Loan for letters of credit, and (ii) up to $20 million under a swingline sub-facility.

The 2023 CoBank Term Loan has scheduled quarterly principal payments in the amounts set forth below, with the outstanding principal balance maturing on July 13, 2029. The 2023 CoBank Revolving Loan may be repaid at any time on or prior to its maturity on July 13, 2028. All amounts outstanding under the 2023 CoBank Credit Facility will be due and payable upon the earlier of the maturity date or the acceleration of the loans and commitments upon an event of default.

Amounts borrowed under the 2023 CoBank Credit Facility bear interest at a rate equal to, at our option, either (i) the secured overnight financing rate (“SOFR”) as administered by the Federal Reserve Bank of New York plus an applicable margin ranging between 2.00% to 3.75% for the 2023 CoBank Term Loan and 1.75% to 3.50% for 2023 CoBank Revolving Loan or (ii) a base rate plus an applicable margin ranging from 1.00% to 2.75% for the 2023 CoBank Term Loan and 0.75% to 2.50% for the 2023 CoBank Revolving Loan. Swingline loans bear interest at the base rate plus the applicable margin for base rate loans. The applicable margin is determined based on the Total Net Leverage Ratio (as defined in the 2023 CoBank Credit Agreement). We also pay a fee ranging from 0.25% to 0.50% on the average daily unused portion of the 2023 CoBank Credit Facility over each calendar quarter.

The 2023 CoBank Credit Agreement contains a financial covenant (as further defined in the 2023 CoBank Credit Agreement) that imposes a maximum Total Net Leverage Ratio of 3.25 to 1.0, measured quarterly, as well as customary representations, warranties and covenants, including covenants limiting additional indebtedness, liens, guaranties, mergers and consolidations, substantial asset sales, investments and loans, sale and leasebacks, transactions with affiliates and fundamental changes. The 2023 CoBank Credit Agreement provides for events of default customary for credit facilities of this type, including but not limited to non-payment, defaults on other debt, misrepresentation, breach of covenants, representations and warranties, insolvency and bankruptcy.

We capitalized $4.5 million of fees associated with the 2023 CoBank Credit Facility, which are being amortized over the life of the debt and $2.3 million were unamortized as of March 31, 2026.

As of March 31, 2026, we had $119.4 million outstanding under the 2023 CoBank Term Loan and $55.5 million under the 2023 CoBank Revolving Loan. As of that date, we had $114.5 million of availability under the 2023 CoBank Revolving Loan. We were in compliance with all financial covenants as of March 31, 2026.

In connection with the proposed Tower Portfolio Transaction, on February 11, 2026, the Company entered into a Consent Agreement (the “Consent”) with CoBank, as Administrative Agent, and the Lenders and Voting Participants (constituting Required Lenders (as defined in the 2023 CoBank Credit Agreement)) party thereto, in connection with the 2023 CoBank Credit Agreement. Pursuant to the terms of the Consent, CoBank and the other Lenders and Voting Participants (constituting Required Lenders) party thereto consented to: (i) the consummation of the Tower Portfolio Transaction; (ii) the distributions of the Net Cash Proceeds (as defined in the 2023 CoBank Credit Agreement) from the Tower Portfolio Transaction to the Company and the minority shareholders of the Commnet Parties; (iii) the Net Cash Proceeds received from the Tower Portfolio Transaction being applied to the repayment of the outstanding 2023 CoBank Revolving Loan rather than the 2023 CoBank Term Loan; and (iv) to the extent that there are Net Cash Proceeds remaining after repaying the outstanding 2023 CoBank Revolving Loan, such Net Cash Proceeds being used by the Company and its subsidiaries for working capital and general corporate purposes. The Consent further provides for the release of the Liens (as defined in the 2023 CoBank Credit Agreement) on the assets being sold in connection with the Tower Portfolio Transaction.

In October 2023, we entered into a two-year, forward starting one-month floating to fixed SOFR interest rate swap agreement. The swap was effective November 13, 2023 in a non-amortizing notional amount of $50.0 million, had a fixed SOFR rate of 4.90% and matured on November 13, 2025.

Letter of Credit Facility

On November 14, 2022, we entered into a General Agreement of Indemnity to issue performance Standby Letters of Credit on behalf of us and our subsidiaries. As of March 31, 2026, $38.9 million of Standby Letters of Credit had been issued under this agreement.

2024 Alaska Credit Facility

On August 29, 2024, Alaska Communications entered into a Credit Agreement (the “2024 Alaska Credit Agreement”) with Bank of America, N.A., as administrative agent, and a syndicate of lenders (the “2024 Alaska Credit

57

Table of Contents

Facility”), to provide debt financing in the form of a $300 million, five-year secured term loan facility (the “2024 Alaska Term Facility”) and a $90 million revolving facility (the “2024 Alaska Revolving Facility”). The maturity date for the 2024 Alaska Credit Facility is August 29, 2029.

The 2024 Alaska Term Facility proceeds were used (a) to refinance Alaska Communications’ outstanding indebtedness under the 2022 Alaska Credit Facility (as defined below) in the amount of approximately $279 million plus accrued and unpaid interest, (b) to pay fees and expenses associated with the completion of this transaction, and (c) for general corporate purposes. As of March 31, 2026, $300.0 million was outstanding under the 2024 Alaska Term Facility.

Proceeds from the 2024 Alaska Revolving Facility are used, subject to certain limitations, (a) to issue letters of credit to replace or backstop existing letters of credit of Alaska Communications and its direct and indirect subsidiaries, and (b) for working capital purposes, capital expenditures and other general corporate purposes. As of March 31, 2026, $21.5 million was outstanding under the 2024 Alaska Revolving Facility and $0.6 million of letters of credit were issued. As a result, $67.9 million was available under the 2024 Alaska Revolving Facility as of March 31, 2026.

The 2024 Alaska Credit Facility also provides for incremental term loans (“Incremental Term Loans”) up to an aggregate principal amount of the greater of $91 million and Alaska Communications’ trailing consolidated twelve-month EBITDA (as defined in the 2024 Alaska Credit Agreement), subject to Alaska Communications meeting certain conditions.

In connection with the 2024 Alaska Credit Facility, we incurred $6.9 million of fees and rolled over $2.1 million of fees for the 2022 Alaska Credit Facility to be amortized over the life of the debt. As of March 31, 2026, we had $6.2 million of unamortized fees, which are being amortized over the life of the debt, associated with the 2024 Alaska Credit Facility.

Amounts outstanding under the 2024 Alaska Credit Facility bear an interest rate equal to, at our option, either (i) the SOFR plus an applicable margin ranging between 3.00% to 4.50% or (ii) a base rate plus an applicable margin ranging from 2.00% to 3.50%. Swingline loans bear interest at the base rate plus the applicable margin for base rate loans. We also pay a fee ranging from 0.25% to 0.40% on the average daily unused portion of the 2024 Alaska Credit Facility over each calendar quarter.

Principal payments on the 2024 Alaska Term Facility are due quarterly commencing in the fourth quarter of 2026 in quarterly amounts as follows: from the fourth quarter of 2026 through the third quarter of 2027, $1,875,000; and from the fourth quarter of 2027 through the second quarter of 2029, $3,750,000. The remaining unpaid balance is due on the final maturity date. Alaska Communications may prepay all revolving loans under the 2024 Alaska Revolving Facility at any time without premium or penalty, subject to certain notice requirements and balance restrictions.

Alaska Communications is required to maintain financial ratios, including (a) a maximum Consolidated Net Total Leverage Ratio (as defined in the 2024 Alaska Credit Agreement) of 4.75:1.00, stepping down to 4.50:1.00 beginning with the third quarter of 2027, and stepping down to 4.25:1.00 beginning with the third quarter of 2028; and (b) a minimum Consolidated Fixed Charge Coverage Ratio of not less than 1.25:1.00. The 2024 Alaska Credit Agreement contains customary covenants restricting the incurrence or assumption of debt, granting or assuming liens, declaring dividends and making other restricted payments, making investments, dispositions, engaging in transactions with affiliates, changes to the nature of business, modifying organizational documents and material agreements, entering into sale and leaseback transactions, amending or making prepayments on certain subordinated debt, and entering into mergers and acquisitions. The 2024 Alaska Credit Agreement contains usual and customary affirmative and negative covenants of the parties for credit facilities of this type or as otherwise deemed appropriate by the administrative agent, subject to customary exceptions and materiality standards. As of March 31, 2026, Alaska Communications was in compliance with all financial covenants.

The 2024 Alaska Credit Facility is secured by substantially all of the personal property and certain material real property owned by Alaska Communications Systems Holdings, the parent company of Alaska Communications (“Holdings”), Alaska Communications, and its wholly owned subsidiaries, excluding, among other things, certain

federal and state licenses where a pledge is prohibited by applicable law or is permitted only with the consent of a governmental authority that has not been obtained.

The Company is not a guarantor under the 2024 Alaska Credit Agreement, and the lenders have no recourse against the Company in the event of an occurrence of an Event of Default (as defined in the 2024 Alaska Credit Agreement).

Alaska Interest Rate Swap Agreements

In November 2023, Alaska Communications entered into two forward starting one-month floating to fixed SOFR interest rate swap agreements. The total non-amortizing notional amount of the agreements is $200 million, with fixed SOFR rates of 4.8695% and 4.8980%. These swap agreements matured on June 30, 2025.

On September 26, 2025, Alaska Communications entered into four forward starting one-month floating to fixed SOFR interest rate swap agreements. The total non-amortizing notional amount of the four agreements was $200 million, with fixed SOFR rates ranging from 3.43% to 3.45% and have a maturity date of September 30, 2027. The swap agreements had a fair value of $0.5 million and $(0.5) million as of March 31, 2026 and December 31, 2025, respectively.

FirstNet Receivables Credit Facility

On March 26, 2020, Commnet Finance, a wholly owned subsidiary of Commnet Wireless, entered into a receivables credit facility with Commnet Wireless and CoBank (the “Receivables Credit Facility”).

The Receivables Credit Facility provided for a senior secured delayed draw term loan in an aggregate principal amount of up to $75.0 million with the proceeds used to acquire certain receivables from Commnet Wireless. The receivables financed and sold under the secured Receivables Credit Facility relate to the obligations of AT&T under the FirstNet Agreement.

On December 27, 2024, CoBank amended the Receivables Credit Facility and extended the delayed draw period to December 31, 2025. There were no further extensions of the draw period.

Interest on the loans accrue at a fixed annual interest rate ranging from 3.21% to 7.13%.

The Receivables Credit Facility contains customary events of termination, representations and warranties, affirmative and negative covenants and events of default customary for facilities of this type.

As of March 31, 2026, Commnet Wireless had $37.6 million outstanding, of which $8.9 million was classified as being current and $28.7 million as long-term on our balance sheet under the Receivables Credit Facility. Commnet Wireless capitalized $0.8 million in fees associated with the Receivables Credit Facility which are being amortized over the life of the debt and $0.3 million were unamortized as of March 31, 2026. 

IDB Credit Facilities

On May 8, 2025, OneGY entered into a Credit Agreement (the “2025 IDB Credit Agreement”) with Inter-American Investment Corporation (“IDB Invest”) to provide (the “2025 IDB Credit Facilities”) a Revolving Credit Commitment of $10.0 million (the “2025 IDB Revolving Facility”) and Term Loan Commitment of up to $30.0 million (the “2025 IDB Term Loan”). The debt is secured by certain assets of OneGY and is not guaranteed by the Company.

Beginning in the second quarter of 2027, amounts drawn on the 2025 IDB Term Loan must be repaid in quarterly principal payments in the amounts set forth below, with the outstanding principal balance maturing on the tenth

anniversary of the effective date. The 2025 IDB Revolving Loan may be repaid at any time on, or prior to, its maturity of 360 days after the first disbursement date.

Amounts borrowed under the 2025 IDB Credit Facilities bear interest at a rate equal to SOFR plus an applicable margin of 2.4% for the 2025 IDB Revolving Facility and 3.0% for the 2025 IDB Term Loan. In the case of the 2025 IDB Term Loan, there is a prepayment fee equal to 1% until the first anniversary from the effective date, 0.5% until the second anniversary from the effective date, and 0.0% thereafter.

The 2025 IDB Credit Agreement contains a financial covenant that imposes on OneGY a maximum Net Financial Debt to EBITDA Ratio and a maximum Debt to Equity ratio and a minimum EBITDA to Net Financial Expense Ratio (each as defined in the 2025 IDB Credit Agreement), as well as customary representations, warranties and covenants. The 2025 IDB Credit Agreement provides for events of default customary for credit facilities of this type, including but not limited to non-payment, defaults on other debt, misrepresentation, breach of covenants, representations and warranties, insolvency and bankruptcy.

As of March 31, 2026, $2.0 million was outstanding under the 2025 IDB Revolving Facility and there were no outstanding borrowings under the 2025 IDB Term loan as of that date. As of March 31, 2026, OneGY was in compliance with all financial covenants.

Sacred Wind Term Debt

Our subsidiary, Sacred Wind, has a term debt facility (the “Sacred Wind Term Debt”) with the US, acting through the Administrator of the Rural Utilities Service (“RUS”), which provides financial assistance in the form of loans under the Rural Electrification Act of 1936 to furnish or improve telecommunications and/or broadband services in rural areas, is secured by substantially all of the assets of Sacred Wind and is an underlying mortgage to the US. These mortgage notes are to be repaid in equal monthly installments covering principal and interest beginning after date of issue and expiring by 2035.

The Sacred Wind Term Debt contains certain restrictions on the declaration or payment of dividends, redemption of capital stock or investment in affiliated companies without the consent of the RUS noteholders. The agreements also contain a financial covenant that Sacred Wind was not in compliance with as of December 31, 2024. Sacred Wind submitted a corrective action plan to comply with the financial covenant by December 31, 2028. The corrective action plan was accepted by the RUS and, as of March 31, 2026, we were in compliance with that corrective action plan.

As of March 31, 2026, $20.5 million was outstanding under the Sacred Wind Term Debt. Of that amount, $3.6 million was current and $16.9 million was long term.

The mortgage notes carry fixed interest rates ranging from 0.88% to 5.0%.

USVI Debt

We, and certain of our subsidiaries, entered into a loan agreement (“OneVI Debt Agreement”) for a $60.0 million loan (the “OneVI Debt”) with National Cooperative Services Corporation (“NCSC”) on July 1, 2016. The OneVI Debt Agreement contains customary representations, warranties, and affirmative and negative covenants (including limitations on additional debt, guaranties, sale of assets and liens) and a financial covenant that limits the maximum ratio

60

Table of Contents

of indebtedness to annual operating cash flow to 3.5 to 1.0 (the “OneVI Net Leverage Ratio”). This covenant is tested on an annual basis at the end of each fiscal year. Interest is paid quarterly at a fixed rate of 4.0% per annum and principal repayment was not required until maturity on July 1, 2026. Prepayment of amounts under the OneVI Debt Agreement are subject to a fee under certain circumstances. The debt is secured by certain assets of the OneVI subsidiaries and is guaranteed by us.

As of March 31, 2026, $60.0 million of the OneVI Debt remained outstanding. Of that amount, $3.4 million was current and $56.6 million was long term.

On May 5, 2022, the OneVI Net Leverage Ratio was amended to 7.0 to 1.0 through the maturity date of July 1, 2026. The OneVI Net Leverage Ratio is tested annually, and we were in compliance with the OneVI Net Leverage Ratio as of December 31, 2025.

On November 5, 2025, the Company and certain of its subsidiaries (the “OneVI Borrowers”) amended the OneVI Debt Agreement (the “OneVI Debt Amendment”) to extend the maturity date of the OneVI Debt from July 1, 2026 to July 1, 2035 (the “Extended Maturity Date”). The OneVI Debt Amendment further provides that the OneVI Debt will continue to accrue interest at the current fixed 4.0% rate through June 30, 2026 and, beginning on July 1, 2026, NCSC will offer, at the Borrowers’ option, a forward fixed rate or variable rate of interest for the remainder of the term of the OneVI Debt through the Extended Maturity Date. If the OneVI Borrowers elect the variable rate, the variable rate will be NCSC’s standard variable rate of interest for long-term loans and subject to change monthly, and the OneVI Borrowers will have the option to convert all or a portion of principal outstanding as of the date specified in the Conversion Notice (as defined in the OneVI Debt Agreement), to NCSC’s standard fixed interest rates for long-term loans at any time thereafter without a fee.

Additionally, the OneVI Debt Amendment provides that the OneVI Debt will continue to require interest-only payments at the current rate through June 30, 2026; beginning on July 1, 2026, the OneVI Debt will be subject to a quarterly repayment schedule.

Additionally, the OneVI Borrowers are to maintain a minimum fixed charge cover ratio of 1.25 to begin December 31, 2026, tested annually thereafter through the Extended Maturity Date. The interest rate will be reset on the original loan maturity date of July 1, 2026.

Factors Affecting Sources of Liquidity

Internally generated funds. The key factors affecting our internally generated funds are demand for our services, competition, regulatory developments, economic conditions in the markets where we operate our businesses and industry trends within the telecommunications industry.  

Restrictions under 2023 CoBank Credit Facility.  Our 2023 CoBank Credit Facility contains customary representations, warranties and covenants, including covenants limiting additional indebtedness, liens, guaranties, mergers and consolidations, substantial asset sales, investments and loans, sale and leasebacks, transactions with affiliates and fundamental changes. 

In addition, the 2023 CoBank Credit Facility contains a financial covenant that imposes a maximum ratio of indebtedness to EBITDA. As of March 31, 2026, we were in compliance with all of the financial covenants of the 2023 CoBank Credit Facility. 

Capital markets.  Our ability to raise funds in the capital markets depends on, among other things, general economic conditions, the conditions of the telecommunications industry, our financial performance, the state of the capital markets and our compliance with SEC requirements for the offering of securities. In August 2025, we filed a new “universal” shelf registration statement with the SEC, to register potential future offerings of up to $300 million of our securities.

Foreign Currency

We translate the assets and liabilities of our foreign subsidiaries from their respective functional currencies, primarily the Guyana Dollar, to US Dollars at the appropriate rates as of the balance sheet date. Changes in the carrying value of these assets and liabilities attributable to fluctuations in rates are recognized in foreign currency translation adjustment, a component of accumulated other comprehensive income on our balance sheet. Income statement accounts are translated using the monthly average exchange rates during the year. Monetary assets and liabilities denominated in a currency that is different from a reporting entity’s functional currency must first be remeasured from the applicable currency to the legal entity’s functional currency. The effect of this remeasurement process is reported in other income within our income statement. During both the three months ended March 31, 2026 and 2025, we recorded $0.4 million in losses on foreign currency transactions. We will continue to assess the impact of our exposure to the Guyana Dollar.

62

Table of Contents

Inflation

Several of our markets have experienced increases in operating costs, some of which we believe are attributable to inflation. If inflation continues or worsens, it could negatively impact our Company by increasing our operating expenses. Inflation may lead to cost increases in multiple areas across our business, for example, rises in the prices of raw materials and manufactured goods, increased energy rates, as well as increased wage pressures and other expenses related to our employees. In particular, where we have agreed to undertake infrastructure build-outs on a fixed budget for our carrier customers or by accepting government grants, inflation may result in build costs that exceed our original budget given the long delays experienced in procuring equipment and materials due to global supply chain delays. To the extent that we are unable to pass on these costs through increased prices, revised budget estimates, or offset them in other ways, they may impact our financial condition and cash flows.

Tariffs

The US government has imposed tariffs on goods imported from various countries to the US, which have been modified, expanded, and in some cases eliminated since that time. Our business is not currently subject to these tariffs. Countries subject to such tariffs or other trade restrictions and other changes in trade policy by the US may, in the future, impose reciprocal or retaliatory tariffs and other trade measures that may impact our business. We are actively monitoring the tariff developments and analyzing the potential impacts on our businesses, cost structures, supply chain and broader economic environment. We are also working closely with our strategic suppliers to manage their potential impact.

The previously implemented tariffs did not have a material impact on our financial condition or results of operations during the three months ended March 31, 2026. However, due to the uncertainty with respect to such tariffs and their evolving nature, we cannot predict the impact, if any, they may have on our business or results in the future.

Availability Under Credit Facilities. In addition to future internally generated funds, we had the following available to us under our credit facilities as of December 31, 2025 and may be able to raise funds in the capital markets by making an offering under our universal shelf registration.

In addition to future internally generated funds, we had the following available to us under our credit facilities, as defined below, as of March 31, 2026 and may be able to raise funds in the capital markets by making an offering under our universal shelf registration.

Item 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Translation and Remeasurement.  We translate the assets and liabilities of our foreign subsidiaries from their respective functional currencies, primarily the Guyana Dollar, to US Dollars at the appropriate rates as of the balance sheet date. Changes in the carrying value of these assets and liabilities attributable to fluctuations in rates are recognized in foreign currency translation adjustment, a component of accumulated other comprehensive income on our balance sheet. Income statement accounts are translated using the monthly average exchange rates during the year.

Monetary assets and liabilities denominated in a currency that is different from a reporting entity’s functional currency must first be remeasured from the applicable currency to the legal entity’s functional currency. The effect of this remeasurement process is reported in other income on our income statement. 

Employee Benefit Plans.  We sponsor pension and other postretirement benefit plans for employees of certain subsidiaries.  Net periodic pension expense is recognized in our income statement. We recognize a pension or other postretirement plan’s funded status as either an asset or liability in our consolidated balance sheet.  Actuarial gains and losses are reported as a component of other comprehensive income and amortized through other income in subsequent periods.

Interest Rate Sensitivity. As of March 31, 2026, we had $298.4 million of variable rate debt outstanding, which is subject to fluctuations in interest rates.  Our interest expense may be affected by changes in interest rates.  We believe that a 100-basis-point change in the interest rates on our variable rate debt would result in a $3.0 million change in our annual interest expense.  We may have additional exposure to fluctuations in interest rates if we again borrow amounts under our revolver loans within our credit facilities.

Item 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as of March 31, 2026. Disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), mean controls and other procedures of an issuer that are designed to ensure that information required to be disclosed by the issuer in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified by the Securities and Exchange Commission’s (“SEC”) rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by an issuer in the reports that it files or submits under the Exchange Act is accumulated and communicated to the issuer’s management, including its principal executive and principal financial officers, or persons performing similar functions as appropriate to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives, and management necessarily applies its judgment in evaluating the cost benefit relationship of possible controls and procedures. Based on the evaluation of our disclosure controls and procedures as of March 31, 2026, our Chief Executive Officer and Chief Financial Officer concluded that, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level.

Changes in Internal Control Over Financial Reporting.

There were no changes in our internal control over financial reporting that occurred during the three months ended March 31, 2026 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Item 1A. Risk Factors

In addition to the other information set forth in this Report, you should carefully consider the factors discussed under Part I, Item 1A “Risk Factors” of our 2025 Annual Report on Form 10-K. The risks described herein and in our 2025 Annual Report on Form 10-K are not the only risks facing our Company. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition and/or operating results.

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

Purchases of Equity Securities by the Issuer. On December 14, 2023, our Board of Directors authorized the repurchase of up to $25.0 million of our common stock, from time to time, on the open market or in privately negotiated transactions (the “2023 Repurchase Plan”).  We have $15.0 million available to be repurchased under that plan as of March 31, 2026.
