Item 1.01	Entry into a Material Definitive Agreement.

The information set forth below in Item 2.01 of this Current Report on Form 8-K (this “Form 8-K”) is incorporated herein by reference.

Item 2.01	Completion of Acquisition or Disposition of Assets

As previously disclosed in the Current Report on Form 8-K filed with the Securities and Exchange Commission (the “SEC”) on February 13, 2026 (the “Initial Form 8-K”), certain subsidiaries of ATN International, Inc. (the “Company”), including Commnet Wireless, LLC (“Commnet”), Arizona Nevada Tower Company, LLC, Commnet Four Corners, LLC, Commnet of Arizona, LLC, Commnet of Nevada, LLC, Excomm, LLC, and Mora Valley Wireless, LLC (collectively, the “Commnet Parties” and, individually, each a “Commnet Party”), entered into that certain Purchase and Sale Agreement (the “Transaction Agreement”), dated as of February 11, 2026, with EIP Holdings IV, LLC, an affiliate of Everest Infrastructure Partners, Inc. (“Everest”), to sell certain tower portfolio sites (representing the substantial majority of the applicable Commnet Parties’ tower portfolio and operations) to Everest (the “Tower Sale Transaction”) for up to $297 million in cash consideration (the “Aggregate Consideration”).

On June 2, 2026 (the “Initial Closing Date”), the Commnet Parties and Everest completed the initial closing of the Tower Sale Transaction (the “Initial Closing”) and entered into an amendment to the Transaction Agreement (the “Amendment Agreement”) to waive certain conditions to the Initial Closing and restate (i) the schedule of tower sites that were conveyed to Everest on the Initial Closing Date (the “Assigned Sites”), (ii) the list of tower sites that will be managed by Everest but still subject to certain managed site conditions prior to conveyance (the “Managed Sites”), and (iii) the list of tower sites that are still subject to certain managed site conditions (the “Deferred Sites”).

At the Initial Closing, Everest paid the Commnet Parties $153.4 million in consideration attributable to the Assigned Sites and $114.3 million in consideration attributable to the Managed Sites. Everest will manage the Managed Sites until the conditions to their conveyance are satisfied, and such Managed Sites are transferred to Everest at one or more subsequent closings (each, a “Subsequent Closing”). At any Subsequent Closing at which one or more Deferred Sites are transferred, Everest will pay a portion of the Aggregate Consideration that is attributable to each Deferred Site.

At the Initial Closing, the Commnet Parties and Everest entered into, among other ancillary agreements, (i) the management agreement for the Managed Sites, (ii) master lease agreements, pursuant to which the Sale Site Subsidiary (as defined in the Transaction Agreement) will lease to the applicable Commnet Party the requisite ground, tower, or other space of the Assigned Sites (the “Leaseback”) for the Company’s continued use, and (iii) a preferred backhaul agreement whereby Commnet and/or one or more of its affiliates will become the preferred backhaul provider for Everest with respect to the Assigned Sites.

The foregoing descriptions of the Transaction Agreement and the Amendment Agreement do not purport to be complete and are qualified in their entireties by reference to the full texts of the Transaction Agreement and the Amendment Agreement, copies of which are filed as Exhibit 10.1 to the Initial Form 8-K and Exhibit 10.1 to this Form 8-K, respectively, and are incorporated herein by reference.

ATN International, Inc. Completes InitialClosing on the Sale of its Towersand Updates 2026 Outlook

ATN received $268 million in cash proceeds uponinitial closing

BEVERLY, Mass., June 2, 2026 (GLOBE NEWSWIRE) -- ATN International, Inc. (“ATN”, the “Company”, “we”, “us”, and “our”) (Nasdaq: ATNI), a leading provider of digital infrastructure and communications services, announced that its subsidiary, Commnet Wireless, LLC and certain of its subsidiaries have completed the initial closing (the “initial closing”) of the previously disclosed sale of Southwestern U.S. towers and related operations (the “Tower Portfolio”). to EIP Holdings IV, LLC, an affiliate of Everest Infrastructure Partners, Inc. for $268 million in cash (the “Tower Portfolio Transaction”).

“The initial closing of the Tower Portfolio Transaction represents an important milestone in building a stronger, more resilient ATN,” said Naji Khoury, Chief Executive Officer of ATN. “With net proceeds from the initial closing broadly the size of our annual Adjusted EBITDA, we are enhancing our liquidity and financial flexibility. This positions us to execute disciplined capital allocation and invest in opportunities that drive performance and deliver long-term stockholder value.”

Subsequent closings, up to an additional $30 million in proceeds, are expected to occur over the next twelve months, subject to the achievement of specified construction and operational milestones at sites not transferred at the initial closing.

As previously disclosed, the Company will allocate $68 million of the initial closing proceeds to repay borrowings outstanding under its CoBank revolving credit facility.

The Company expects the impact of the initial closing will reduce the remaining seven months of 2026 consolidated and US Telecom segment revenues by $3 million, operating income by $4 million, and Adjusted EBITDA^1^ by $7 million. As a result, the Company’s previously disclosed 2026 full-year Adjusted EBITDA^1^ outlook of $190 to $200 million is now expected to be $183 million to $193 million.

Use of Non-GAAP Financial Measures and Definitionof Terms

In addition to financial measures prepared in accordance with generally accepted accounting principles (“GAAP”), this press release also contains forward-looking Adjusted EBITDA, a non-GAAP financial measure.

^1^Adjusted EBITDA is defined as Operating income (loss) before depreciation and amortization expense, transaction-related charges, restructuring and reorganization expenses, the loss on dispositions, transfers and contingent consideration, and non-cash stock-based compensation.

The Company believes that the inclusion of this non-GAAP financial measure helps investors gain a meaningful understanding of the Company's core operating results and enhances the usefulness of comparing such performance with prior periods. Management uses this non-GAAP measure, in addition to GAAP financial measures, as the basis for measuring the Company’s core operating performance and comparing such performance to that of prior periods. The forward-looking non-GAAP financial measure included in this press release is not meant to be considered superior to or a substitute for results of operations prepared in accordance with GAAP and should be used supplementally to the Company’s GAAP financial results.

Forward-looking Adjusted EBITDA for the full-year 2026 excludes potential charges or gains that may be recorded during the fiscal year, including among other things such as restructuring and reorganization expenses, transaction-related expenses and gains or losses on dispositions, transfers and contingent consideration. The Company has not attempted to provide a reconciliation of such forward-looking non-GAAP earnings guidance to the comparable GAAP measure, as permitted by Item 10(e)(1)(i)(B) of Regulation S-K, because of the impact and timing of these potential charges or gains is inherently uncertain and difficult to predict and is unavailable without unreasonable efforts. In addition, the Company believes such reconciliation would imply a degree of precision and certainty that could be confusing to investors. Such items could have a substantial impact on GAAP measures of the Company’s financial performance.

Cautionary Language Concerning Forward-LookingStatements

This press release contains forward-looking statements relating to, among other matters, the Company’s future financial performance, business goals and objectives, and results of operations, its future revenues, operating income, cash flows, network and operating costs, Adjusted EBITDA, and capital investments; additional closings of the remaining Tower Portfolio and the timing thereof; the Company’s liquidity; and management’s plans 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 the Company’s operations, including operating margins, revenues, capital expenditures, the impact of cost savings initiatives, and the retention of and future growth of the Company’s subscriber base and average revenue per user; (2) our ability to satisfy other remaining conditions to achieve subsequent closings with respect to sites in the Tower Portfolio; (3) with respect to the use of proceeds resulting from the Tower Portfolio, the timing, manner and extent to which such proceeds are deployed may be affected by future market conditions, potential changes in tax laws and the Company's ability to develop corporate investment and strategic opportunities; (4) government regulation of the Company’s businesses, which may impact the Company’s telecommunications licenses, the Company’s revenue and the Company’s operating costs; (5) the impact (if any) of geopolitical instability and U.S. military presence in the Caribbean; (6) management transitions, and the loss of, or an inability to recruit skilled personnel in the Company’s various jurisdictions, including key members of management; (7) the Company’s reliance on a limited number of key suppliers and vendors for timely and cost-effective supply of equipment and services relating to the Company’s network infrastructure; (8) the Company’s ability to satisfy the needs and demands of the Company’s major carrier customers; (9) the Company’s ability to realize expansion plans for its fiber markets; (10) the adequacy and expansion capabilities of the Company’s network capacity and customer service system to support the Company’s customer growth; (11) the Company’s ability to efficiently and cost-effectively upgrade the Company’s networks and information technology platforms to address rapid and significant technological changes in the telecommunications industry; (12) the Company’s continued access to capital and credit markets on terms it deems favorable; (13) the Company’s ability to successfully replace revenue declines in its US Telecom businesses as a result of the pending US tower portfolio sale through carrier, enterprise broadband, and consumer-based broadband services; (14) ongoing risk of an economic downturn, political, geopolitical and other risks and opportunities impacting the Company’s operations, including those resulting from changes and uncertainties related to trade policies and tariff regulations, financial market volatility and disruption, uncertain economic conditions in the U.S. and abroad, inflationary concerns, and other macroeconomic headwinds including increased costs and supply chain disruptions; (15) the occurrence of weather events and natural catastrophes and the Company’s ability to secure the appropriate level of insurance coverage for these assets; 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. The Company undertakes no obligation and has no intention to update these forward-looking statements to reflect actual results, changes in assumptions, or changes in other factors that may affect such forward-looking statements, except as required by applicable law.

UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIALINFORMATION

The following unaudited pro forma condensed consolidated financial information has been prepared by the Company and gives pro forma effect to the completion of Initial Closing of the Company’s Tower Sale Transaction with Everest. Capitalized terms used and not defined herein shall have the meanings ascribed to them in the Form 8-K filed with the Securities and Exchange Commission (the “SEC”) on June 3, 2026. The Company, through its subsidiaries, the Commnet Parties, completed the Initial Closing of the Tower Sale Transaction with Everest, on June 2, 2026, pursuant to which Everest purchased certain tower portfolio sites in the southwestern United States. At the Initial Closing the Company received cash payment of $267.7 million. This amount consists of $255.7 million recorded as sale consideration as well as $12.0 million received at the Initial Closing and recorded as deferred pending the Company’s achievement of certain conditions on Managed Sites subsequent to the Initial Closing. The Transaction Agreement contemplates Subsequent Closings at which one or more Managed Sites or Deferred Sites will be transferred to Everest when and if certain site conditions are met. The Company can receive additional payments of up to $29.8 million if these site conditions are met. The unaudited pro forma condensed consolidated financial information does not include any impact related to Subsequent Closings. The Tower Sale Transaction does not qualify as a discontinued operation because the disposition does not represent a strategic shift that has a major effect on the Company’s operations and financial results.

In addition, in connection with the Tower Sale Transaction, the Company entered into a Consent with CoBank requiring the Company to repay amounts outstanding under the Company’s Revolving Loan.

The following unaudited pro forma condensed consolidated financial information is provided for informational purposes only. The information is not necessarily indicative of what the financial position or results of operations of the Company would have been if the Tower Sale Transaction had been completed as of and for the periods indicated. In addition, the information does not purport to project the future financial position or operating results of the Company.

The unaudited pro forma condensed consolidated financial information is based on financial statements prepared in accordance with accounting principles generally accepted in the United States of America. In addition, the information is based upon available information and a number of assumptions that the Company considers to be reasonable, and have been made solely for purposes of developing such unaudited pro forma condensed consolidated financial information for illustrative purposes in compliance with the disclosure requirements of Article 11 of Regulation S-X.

The unaudited pro forma condensed consolidated statements of operations give effect to the Initial Closing of the Tower Sale Transaction as if it had occurred on January 1, 2025. The unaudited pro forma condensed consolidated balance sheet gives effect to the Initial Closing of the Tower Sale Transaction as if it had been consummated on March 31, 2026. You should read this unaudited pro forma financial information in connection with the accompanying notes to the unaudited pro forma condensed consolidated financial information and the historical financial statements of the Company filed with the SEC.

Pro forma adjustments related to the unaudited pro forma condensed consolidated statements of operations give effect to certain events that are (i) directly attributable to the Tower Sale Transaction, (ii) factually supportable and (iii) expected to have a continuing impact on the Company’s results. Pro forma adjustments related to the unaudited pro forma condensed consolidated balance sheet give effect to events that are directly attributable to the Initial Closing of the Tower Sale Transaction, and that are factually supportable regardless of whether they have a continuing impact or are non-recurring.

The pro forma adjustments are preliminary and have been made solely for the purpose of providing unaudited pro forma financial information and amounts may change based on a final determination of the book value of assets, liabilities, and other closing date adjustment amounts. The Company is still in the process of evaluating the tax implications of the Tower Sale Transaction on its consolidated tax provision. Thus, the final loss may differ in material respects from that presented in the unaudited pro forma financial information.

Note 2. Preliminary Purchase PriceAllocation

On June 2, 2026, the Company completed the Initial Closing of the Tower Sale Transaction and sold a portion of its Tower Portfolio to Everest for cash payments of $267.7 million. This amount consists of $255.7 million recorded as sale consideration as well as $12.0 million received at the Initial Closing that will be deferred pending the Company’s achievement of certain conditions on Managed Sites subsequent to the Initial Closing. The Transaction Agreement contemplates Subsequent Closings at which one or more Managed Sites or Deferred Sites will be transferred to Everest when and if certain site conditions are met. The Company can receive additional payments of up to $29.8 million if these site conditions are met. The net book value of the assets and liabilities being transferred is $27.2 million, as of March 31, 2026. The Company incurred $8.9 million of transaction related charges pertaining to legal, accounting and consulting services associated with the Tower Sale Transaction.

Note 3. Pro Forma Adjustments

The following is a summary of the pro forma adjustments reflected in the unaudited pro forma condensed consolidated financial statements based on preliminary estimates, which may change as additional information is obtained:

(a)	Disposition – This adjustment removes the disposed assets and the associated revenue and expense. Refer to Note 2 for the assets<br>and liabilities disposed. The adjustment to retained earnings represents the net book value of the assets disposed.
(b)	Purchase Price – The Company received $267.7 million of cash payments consisting of $255.7 million of cash consideration and<br>a deferral of $12.0 million related to the achievement of certain closing conditions on Managed Sites after the Initial Closing. As a<br>result of the disposition, the pro forma financials reflect a gain of $228.5 million before income taxes and transaction costs. In addition,<br>the pro forma results include tax expense of $54.9 million, consisting of $45.6 million of current and $9.3 of deferred income tax expense,<br>and gains allocated to non-controlling interest of $19.1 million. These amounts were not included in the unaudited pro forma condensed<br>consolidated statement of operations for the year ended December 31, 2025, due to their non-recurring nature, but have been recorded<br>in the unaudited pro forma condensed consolidated balance sheet as of March 31, 2026. The adjustment to retained earnings reflects<br>consideration received less tax expense and income allocated to non-controlling interests. The Company is currently evaluating the tax<br>impact of the Tower Sale Transaction, and tax accruals may not be the actual amount of taxes paid by the Company.
---	---
(c)	Credit Facility Repayment – The Company paid $67.9 million on its Revolving Loan at the Initial Closing, and this adjustment<br>represents the repayment of $55.5 million that was outstanding as at March 31, 2026. In addition, interest expense on the Revolving<br>Loan is removed from the pro forma condensed consolidated statement of operations.
---	---
(d)	Income taxes –This adjustment reflects the tax expense associated with the Initial Closing of the Tower Sale Transaction and<br>pro forma adjustments. The adjustment is calculated based on a blended federal statutory and state tax rate of 25%.
---	---
(e)	Transaction-related charges – This adjustment removes expenses pertaining to legal, accounting and consulting services associated<br>with the Tower Sale Transaction incurred prior to March 31, 2026 from the pro forma condensed consolidated statement of operations<br>and accrues such expenses payable at the Initial Closing of the Tower Sale Transaction in the pro forma condensed consolidated balance<br>sheet.
