Item 1.01

Entry into a Material Definitive Agreement.

Purchase and Sale Agreement

On February 11, 2026 (the “Signing Date”), certain subsidiaries of ATN International, Inc. (the “Company”), including Commnet Wireless, LLC, 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”) 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 the applicable Commnet Parties’ tower portfolio and operations (the “Tower Portfolio”)) to Everest for up to $297 million in cash consideration (the “Aggregate Consideration”). The Aggregate Consideration is subject to certain adjustments and prorations as set forth in the Transaction Agreement (collectively, the “Consideration Adjustments”). The Transaction Agreement contemplates Everest’s acquisition of the Tower Portfolio (the “Transaction”) through Everest’s purchase of membership interests in a Delaware limited liability company (the “Sale Site Subsidiary” and, together with the Commnet Parties and Everest, the “Parties”) that is to be formed prior to the Initial Closing (as defined below) and to which the Commnet Parties will transfer and convey all of the Commnet Parties’ respective rights and interests in the Tower Portfolio.

The Transaction may be completed in one or more closings (each, a “Closing”). 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 “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 (the “Assigned Sites”), which sites have not yet satisfied all such conditions but for which Everest is prepared to assume management pending satisfaction of such conditions (the “Managed Sites”), and which sites are not yet constructed or are subject to other conditions that will continue to be managed by Commnet until such conditions are satisfied (the “Deferred Sites”).

At the Initial Closing, the Commnet Parties will assign and transfer to the Sale Site Subsidiary all of the Assigned Sites, and Everest will purchase all of the issued and outstanding membership interests in the Sale Site Subsidiary. At the Initial Closing, Everest will pay the portion of the Aggregate Consideration attributable to the Assigned Sites and the Managed Sites, and, pursuant to a management agreement, will manage the Managed Sites until the conditions to their conveyance are satisfied and such 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 the portion of the Aggregate Consideration attributable to such Deferred Site(s) through the acquisition of membership interests of one or more newly formed additional sale site subsidiaries.

At the Initial Closing, the Parties will enter into, among other ancillary agreements, (i) the management agreement for the Managed Sites, (ii) master lease agreements, pursuant to which the Sale Site Subsidiary will lease to the applicable Commnet Party the requisite ground, tower, or other space of the Assigned Site (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 Initial Closing is expected to occur in the second quarter of 2026. 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. If the Transaction Agreement is terminated under certain circumstances that are not the fault of the Commnet Parties, Everest will be required to pay the Commnet Parties a termination fee equal to approximately $14.9 million.

The foregoing description of the Transaction Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Transaction Agreement, a copy of which is filed as Exhibit 10.1 to this Current Report on Form 8-K (this “Form 8-K”) and is incorporated herein by reference.

Consent Agreement

In connection with the proposed Transaction and the Leaseback, on the Signing Date, the Company entered into a Consent Agreement (the “Consent”) with CoBank, ACB (“CoBank”) (as Administrative Agent) and the Lenders and Voting Participants (constituting Required Lenders) party thereto, in connection with the Company’s Credit Agreement, dated as of July 13, 2023, by and among the Company, certain of the Company’s subsidiaries as guarantors, CoBank (as Administrative Agent, Lead Arranger, Swingline Lender, an Issuing Lender and a Lender), Fifth Third Bank, N.A. (as Joint Lead Arranger and a Lender), and MUFG Bank, Ltd. (as a Joint Lead Arranger and a Lender) (the “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 Transaction; (ii) the distributions of the Net Cash Proceeds (as defined in the Credit Agreement) from the Transaction to the Company and the minority shareholders of the Commnet Parties; (iii) the Net Cash Proceeds received from the Transaction being applied to the repayment of the outstanding Revolving A-1 Loan (as defined in the Credit Agreement) rather than the Term Loan (as defined in the Credit Agreement); and (iv) to the extent that there are Net Cash Proceeds remaining after repaying the outstanding Revolving A-1 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 Credit Agreement) on the assets being sold in connection with the Transaction.

The foregoing description of the Consent does not purport to be complete and is qualified in its entirety by reference to the full text of the Consent, a copy of which is filed as Exhibit 10.2 to this Form 8-K and is incorporated herein by reference.
