ORGANIZATION AND BUSINESS OPERATIONS
ORGANIZATION AND BUSINESS OPERATIONS	1. ORGANIZATION AND BUSINESS OPERATIONS The Company is a leading provider of digital infrastructure and communications services with a focus on rural and remote markets in the United States, and internationally, including Bermuda and the Caribbean region. The Company has developed significant operational expertise and resources that it uses to augment its capabilities in its local markets. With this support, the Company’s operating subsidiaries are able to improve their quality of service with greater economies of scale and expertise than would typically be available in the size markets they operate in. The Company provides management, technical, financial, regulatory, and marketing services to its operating subsidiaries and typically receives a management fee calculated as a percentage of their revenues, which is eliminated in consolidation. The Company also actively evaluates investment opportunities and other strategic transactions, both domestic and international, and generally looks for those that it believes fit the Company’s profile of telecommunications businesses and have the potential to complement the Company’s “First-to-Fiber” and “Glass & Steel™” approach in markets while keeping a focus on generating excess operating cash flows over extended periods of time. The Company uses the cash generated from its operations to maintain an appropriate ratio of debt and cash on hand and to fund growth and capital expenditures, to return cash to its stockholders through dividends or stock repurchases, and make strategic investments or acquisitions. For further information about the Company’s financial segments and geographical information about its operating revenues and assets, see Notes 1 and 12 to the Consolidated Financial Statements included in this Report.

These services include consumer broadband and high-speed data solutions for businesses. For some markets, fixed services also include video services and revenue derived from support under certain government programs. ● Carrier Telecommunication Services . The Company delivers services to other telecommunications providers including the leasing of critical network infrastructure such as tower and transport facilities, wholesale roaming and long distance voice services, site maintenance and international long-distance services. ● Managed Services . The Company provides information technology services such as network, application, infrastructure and hosting services to both its business and consumer customers to complement its fixed services in its existing markets.

BASIS OF PRESENTATION The accompanying condensed consolidated financial statements have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission (“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. 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, 2023, filed with the SEC on March 15, 2024. 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 December 2023, the FASB released ASU 2023-09, titled "Enhancements to Income Tax Disclosures," with the aim of improving the clarity and usefulness of income tax disclosures. The update focuses primarily on enhancing disclosures related to rate reconciliation and income taxes paid. ASU 2023-09 becomes effective for annual reporting periods starting after December 15, 2024, with early adoption permitted. While the changes prescribed by ASU 2023-09 are implemented prospectively, retrospective application is also allowed. The Company has chosen not to early adopt this standard and is currently assessing its potential impact on our consolidated financial statements and accompanying disclosures. In November 2023, the FASB issued ASU No. 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures” (ASU 2023-07), which requires that a public entity disclose, on an interim and annual basis, significant segment expense categories and amounts that are regularly provided to its chief operating decision maker (CODM) and included in each reported measure of segment profit or loss. An entity must also disclose, by reportable segment, the amount and composition of other expenses. The standard requires an entity to disclose the title and position of its CODM and explain how the CODM uses these reported measures in assessing segment performance and determining how to allocate resources. ASU 2023-07 will be effective for annual periods beginning after December 15, 2023, and interim periods beginning after December 31, 2024, with retrospective application. The standard allows early adoption of these requirements and we are currently evaluating the disclosure impacts of our adoption.

Refer to Note 8. Contract Assets and Liabilities The Company recognizes contract assets and liabilities on its balance sheet. Contract assets represent unbilled amounts typically resulting from consumer Mobility contracts with both a multiyear service period and a promotional discount. In these contracts, the revenue recognized exceeds the amount billed to the customer. The current portion of the contract asset is recorded in prepayments and other current assets and the noncurrent portion is included in other assets on the Company’s balance sheets. Contract liabilities consist of advance payments and billings in excess of revenue recognized. Mobility and Fixed revenue for postpaid customers is generally billed in advance and recognized over the period that the corresponding service is rendered to customers. To the extent the service is not provided by the reporting date the amount is recognized as a contract liability. Prepaid service, including Mobility services, sold to customers is recorded as deferred revenue prior to the commencement of services. Contract liabilities also include certain long term fixed business and carrier service customer contracts. The current portion of contract liabilities are recorded in advanced payments and deposits and the noncurrent portion is included in deferred revenue, long-term on the Company’s balance sheets. In July 2019, the Company entered into a Network Build and Maintenance Agreement with AT&T Mobility, LLC (“AT&T”) that was subsequently amended through December 31, 2023 (the “FirstNet Agreement”). In connection with the FirstNet Agreement, the Company is building a portion of AT&T’s network for the First Responder Network Authority in or near the Company’s current operating areas in the western United States (the “FirstNet Transaction”). The FirstNet Transaction includes construction and service performance obligations. The current portion of receivables under this agreement is recorded in customer receivable and the long-term portion is recorded in customer receivable long-term on the Company’s balance sheet. In May 2023, the Company amended its current roaming agreement and entered into a carrier management services agreement with Verizon Wireless (the “Verizon CMS Agreement”). The transaction includes service performance obligations under which revenue is recognized over time. The Company allocates the transaction price of these agreements to each performance obligation based on the relative standalone selling price of each performance obligation in the contract. The standalone selling price is the estimated price the Company would charge for the good or service in a separate transaction with similar customers in similar circumstances. Contract assets and liabilities consisted of the following (amounts in thousands): June 30, 2024 December 31, 2023 $ Change % Change Contract asset – current $ 3,701 $ 3,616 $ 85 2.4 % Contract asset – noncurrent 5,149 5,509 (360) (6.5) % Contract liability – current (32,283) (30,990) (1,293) 4.2 % Contract liability – noncurrent (59,373) (64,035) 4,662 (7.3) % Net contract liability $ (82,806) $ (85,900) $ 3,094 (3.6) % The decrease in the Company’s net contract liability was due to the timing of customer prepayments, contract billings, and recognition of deferred revenue. During the six months ended June 30, 2024, the Company recognized revenue of Contract Acquisition Costs The June 30, 2024 and 2023 balance sheets include contract acquisition costs of $10.9 million and $9.7 million, respectively, in other assets. . During the three and six months ended June 30, 2023, the Company amortized Remaining Performance Obligations Remaining performance obligations represent the transaction price allocated to unsatisfied performance obligations of certain multiyear Mobility and Fixed communication services contracts, Managed Services contracts, and the Company’s Carrier Services construction and service contracts. The transaction price allocated to unsatisfied performance obligations was million at June 30, 2024. The Company expects to satisfy approximately p p r o x i m a t e l million annually from 2026 through 2031. The Company has certain Mobility, Fixed, and Carrier Services contracts where the transaction price is allocated to remaining performance obligations. However, the Company omits these contracts from its disclosure by applying the right to invoice, Disaggregation The Company's revenue is presented on a disaggregated basis in Note 12 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 the revenue transaction 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. The Company had gross accounts receivable of $114.8 million and an allowance for credit losses of $16.4 million as of June 30, 2024. In addition, the Company had receivables under the FirstNet Agreement totaling million was long-term. At December 31, 2023, the Company had gross accounts receivable of million was long-term. The Company monitors receivables through the use of historical operating data adjusted for the expectation of future performance as appropriate.

USE OF ESTIMATES
USE OF ESTIMATES	5. USE OF ESTIMATES The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the financial statements and the reported amounts of revenue and expenses during the reporting periods. The most significant estimates relate to the allowance for credit losses on trade receivables, useful lives of the Company’s fixed and finite-lived intangible assets, allocation of purchase price to assets acquired and liabilities assumed in business combinations, fair value of indefinite-lived intangible assets, goodwill and income taxes. Actual results could differ significantly from those estimates.

FAIR VALUE MEASUREMENTS AND INVESTMENTS	Jun. 30, 2024
FAIR VALUE MEASUREMENTS AND INVESTMENTS
FAIR VALUE MEASUREMENTS AND INVESTMENTS	6. 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 which 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. Assets and liabilities of the Company measured at fair value on a recurring basis as of June 30, 2024 and December 31, 2023 are summarized as follows (in thousands): June 30, 2024 Significant Other Quoted Prices in Observable Unobservable Active Markets Inputs Inputs Description (Level 1) (Level 2) (Level 3) Total Short term investments $ 300 $ — $ — $ 300 Other investments — — 931 931 Employee benefit plan investments 3,007 — — 3,007 Interest rate swap — (28) — (28) Alaska Communications redeemable common units — — (5,744) (5,744) Alloy redeemable common units — — (14,760) (14,760) Warrants on Alaska Communications redeemable common units — — (249) (249) Total assets and liabilities measured at fair value $ 3,307 $ (28) $ (19,822) $ (16,543) December 31, 2023 Significant Other Quoted Prices in Observable Unobservable Active Markets Inputs Inputs Description (Level 1) (Level 2) (Level 3) Total Short term investments $ 300 $ — $ — $ 300 Other investments — — 1,197 1,197 Employee benefit plan investments 3,014 — — 3,014 Interest rate swap — (1,750) — (1,750) Alaska Communications redeemable common units — — (11,063) (11,063) Alloy redeemable common units — — (14,760) (14,760) Warrants on Alaska Communications redeemable common units — — (249) (249) Total assets and liabilities measured at fair value $ 3,314 $ (1,750) $ (24,875) $ (23,311) Other Investments The Company holds investments in equity securities consisting of noncontrolling investments in privately held companies. The investments are accounted for using equity method accounting, 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 a result, the Company transferred These investments are included with other assets on the consolidated balance sheets. Redeemable Common Units and Warrants The Company has issued redeemable common units, and warrants to purchase additional common units, in consolidated subsidiaries of the Company. The instruments are redeemable at the option of the holder. Both the common units and warrants to purchase common units are recorded at fair value in the Company’s financial statements. The common units are recorded in redeemable noncontrolling interest and the warrants are recorded in other liabilities on the Company’s balance sheets. The put options for the Alloy redeemable common units begin in November 2026. The put options for the Alaska Communications redeemable common units begin the earlier of a public offering or July 2028. 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 The carrying amounts of cash and cash equivalents, accounts receivable, and accounts payable and accrued expenses approximate their fair values because of the relatively short-term maturities of these financial instruments. The fair value of long-term debt is estimated using Level 2 inputs. At June 30, 2024, the fair value of long-term debt, including the current portion, was $583.7 million and its book value was $586.9 million. At December 31, 2023, the fair value of long-term debt, including the current portion, was $571.6 million and its book value was $562.9 million.

LONG-TERM DEBT	7. LONG-TERM DEBT 2023 CoBank Credit Facility On July 13, 2023, the Company, along with certain of its subsidiaries as guarantors, entered into a new Credit Agreement with CoBank, ACB and a syndicate of other lenders (as may be amended from time to time, the “2023 CoBank Credit Facility”). On July 10, 2024, the Company amended its credit facility to add certain subsidiaries as guarantors and to provide further flexibility for the Company to take on certain grant and government program obligations. The amendment to the 2023 CoBank Credit Facility is filed herewith as Exhibit 10.1. 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”). The Company may use (i) up to $25 million under the 2023 CoBank Credit Facility for letters of credit, and (ii) up to $20 million under a swingline sub-facility. Upon the closing of the 2023 CoBank Credit Facility, the Company drew all of the 2023 CoBank Term Loan and approximately $13.6 million of the 2023 CoBank Revolving Loan. These borrowings were used to repay $139.5 million of debt outstanding under the 2019 CoBank Credit Facility at close. The 2023 CoBank Term Loan must be repaid in 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. 2023 CoBank Term Loan Quarterly Payment Dates 2023 CoBank Term Loan Quarterly Repayments December 31, 2023 – June 30, 2025 $812,500 (2.5% per annum) September 30, 2025 – June 30, 2026 $1,625,000 (5% per annum) September 30, 2026 – June 30, 2029 $2,437,500 (7.5% per annum) Amounts borrowed under the 2023 CoBank Credit Facility bear interest at a rate equal to, at the Company’s option, either (i) the secured overnight financing rate as administered by the Federal Reserve Bank of New York (SOFR) plus an applicable margin ranging between 2.00% to 3.75% for the 2023 CoBank Term Loan or 1.75% to 3.50% for Revolving Loans or (ii) a base rate plus an applicable margin ranging from 1.00% to 2.75% for the Term Loan or 0.75% to 2.50% for the 2023 CoBank Revolving Loans. Swingline loans will bear interest at the base rate plus the applicable margin for base rate loans. The base rate is equal to the higher of (i) 1.00% plus the one-month SOFR rate (ii) the federal funds effective rate (as defined in the 2023 CoBank Credit Agreement) plus 0.50% per annum; and (iii) the prime rate (as defined in the 2023 CoBank Credit Agreement). The applicable margin is determined based on the ratio (as further defined in the 2023 CoBank Credit Agreement) of the Company’s maximum Total Net Leverage Ratio.

COMMITMENTS AND CONTINGENCIES
COMMITMENTS AND CONTINGENCIES	13. 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, GTT, has been subject to other long-standing litigation proceedings and disputes in Guyana that have not yet been resolved. The Company believes that, except for the items discussed below, for which the Company is currently unable to predict the final outcome, the disposition of matters currently pending will not have a material adverse effect on the Company’s financial position or results of operations. Beginning in 2006, the National Frequency Management Unit (now the Telecommunications Agency, or the “NFMU/TA”) and GTT have been engaged in discussions regarding the amount of and methodology for calculation of spectrum fees payable by GTT in Guyana. Since that time, GTT has made payments of undisputed spectrum fees as amounts invoiced by the NFMU, and to its successor, the Telecommunications Authority (“TA”). There have been limited further discussions on the subject of a revised spectrum fee methodology with the TA. GTT has filed several lawsuits in the High Court of Guyana asserting that, despite its denials, Digicel is engaged in international bypass in violation of GTT’s exclusive license rights, the interconnection agreement between the parties, and the laws of Guyana. Digicel filed counterclaims alleging that GTT 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, the Company cannot accurately predict at this time when the consolidated suit will reach a court of final determination. GTT 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. GTT has maintained that it has no unpaid corporation tax due to the GRA and that any liability GTT 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. GTT’s position has been upheld by various High Court rulings made in its favor including most recently in February 2024, and while all matters have been appealed by the GRA, only one remains pending for determination by the High Court. In February 2020, the Company’s Alaska Communications subsidiary received a draft audit report from USAC in connection with USAC’s inquiry into Alaska Communications’ funding requests under the Rural Health Care Support Program for certain customers for the time period of July 2012 through June 2017. Alaska Communications also received a Letter of Inquiry on March 18, 2018, and subsequent follow up information requests, from the FCC Enforcement Bureau requesting historical information regarding Alaska Communications’ participation in the FCC’s Rural Health Care Support Program. On May 8, 2024, we entered into a Consent Decree with the FCC Enforcement Bureau, regarding both the USAC and FCC Enforcement Bureau’s investigation and agreed to (i) pay a settlement amount of approximately $6.3 million, and (ii) enter into a three-year compliance agreement in connection with Alaska Communication’s continued participation in the RHC Program. At this time, we believe that we can comply with all of the terms of the compliance agreement. The settlement amount of $6.3 million consists of a $5.3 million cash payment and the $1.0 million forgiveness of certain receivables, both of which have been accrued on the Company’s balance sheet as of June 30, 2024. As such, this settlement will not impact the statement of operations in future periods. With respect to all of the foregoing unresolved matters, the Company believes that some adverse outcome is probable and has accordingly accrued $12.5 million as of June 30, 2024 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.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
BASIS OF PRESENTATION	The accompanying condensed consolidated financial statements have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission (“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. 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, 2023, filed with the SEC on March 15, 2024. 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	Recent Accounting Pronouncements In December 2023, the FASB released ASU 2023-09, titled "Enhancements to Income Tax Disclosures," with the aim of improving the clarity and usefulness of income tax disclosures. The update focuses primarily on enhancing disclosures related to rate reconciliation and income taxes paid. ASU 2023-09 becomes effective for annual reporting periods starting after December 15, 2024, with early adoption permitted. While the changes prescribed by ASU 2023-09 are implemented prospectively, retrospective application is also allowed. The Company has chosen not to early adopt this standard and is currently assessing its potential impact on our consolidated financial statements and accompanying disclosures. In November 2023, the FASB issued ASU No. 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures” (ASU 2023-07), which requires that a public entity disclose, on an interim and annual basis, significant segment expense categories and amounts that are regularly provided to its chief operating decision maker (CODM) and included in each reported measure of segment profit or loss. An entity must also disclose, by reportable segment, the amount and composition of other expenses. The standard requires an entity to disclose the title and position of its CODM and explain how the CODM uses these reported measures in assessing segment performance and determining how to allocate resources. ASU 2023-07 will be effective for annual periods beginning after December 15, 2023, and interim periods beginning after December 31, 2024, with retrospective application. The standard allows early adoption of these requirements and we are currently evaluating the disclosure impacts of our adoption.
