Item 5.02 Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.
On July 27, 2026, Mary Mabey agreed to step down as Senior Vice President and General Counsel (the “Separation”) of ATN International, Inc. (the “Company”), effective as of October 31, 2026 (the “Separation Date”). As currently contemplated, Ms. Mabey will continue to serve as Senior Vice President and General Counsel and receive her current base salary through the Separation Date. The Separation is not the result of any disagreement with the Company regarding its operations, policies, or practices, and the Company thanks Ms. Mabey for her service and contributions.
In connection with the Separation, Ms. Mabey and the Company entered into that certain Transition Agreement, dated as of July 27, 2026 (the “Transition Agreement”). In addition to the severance benefits that Ms. Mabey will be entitled to under Section 2(b) of that certain Executive Agreement, dated as of March 9, 2023, by and between the Company and Ms. Mabey (the “Executive Agreement” and, together with the Transition Agreement, the “Agreements”), the Transition Agreement provides that she will be eligible to receive her 2026 annual incentive bonus with a target value equal to 60% of her current annual base salary, pro-rated for Ms. Mabey’s period of employment during 2026 (the “2026 Pro-Rated Annual Bonus”). The actual payable amount of the 2026 Pro-Rated Annual Bonus will be determined by the Compensation Committee of the Company’s Board of Directors based upon Company performance for the fiscal year ending December 31, 2026 (the “2026 year”) (weighted 50%) and Ms. Mabey’s individual performance for the 2026 year (weighted 50%), and will be paid in 2027 when such bonuses are paid to the Company’s employees. Ms. Mabey’s outstanding equity awards will continue to vest through the Separation Date, subject to the terms and conditions of the ATN International, Inc. 2023 Equity Incentive Plan and the applicable award agreements. Notwithstanding the foregoing, Ms. Mabey’s receipt of the benefits provided for under each of the Agreements is subject to, among other things, (i) her execution and non-revocation of a release and waiver of claims in favor of the Company following the Separation Date and (ii) her continued service through the Separation Date, unless otherwise determined by the Company.
The foregoing description of the Transition Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Transition Agreement, a copy of which is attached hereto as Exhibit 10.1 and is incorporated herein by reference.
