PROXY STATEMENT
FOR THE 2024 ANNUAL MEETING OF STOCKHOLDERS
TO BE HELD ON JUNE 18, 2024
GENERAL INFORMATION ABOUT VOTING
This Proxy Statement is furnished in connection with the solicitation of proxies by the Board of Directors (the “Board”) of ATN International, Inc., a Delaware corporation, for use at the 2024 Annual Meeting of Stockholders to be held on June 18, 2024, at 9 a.m. MT (the “Annual Meeting”), or any adjournments or postponements thereof.
Pursuant to certain rules of the U.S. Securities and Exchange Commission (“SEC”) that allow issuers to furnish proxy materials to stockholders over the Internet, we are posting our proxy materials on the Internet and delivering a Notice of Internet Availability of Proxy Materials (the “Notice”) containing instructions on how to access or request a copy of our Proxy Statement, our Annual Letter to Stockholders and our Annual Report on Form 10-K for the year ended December 31, 2023 (excluding exhibits). We first mailed the Notice to stockholders on April 29, 2024, unless they requested printed copies of our proxy materials. If you would like to receive a paper or e-mail copy of our proxy materials, please follow the instructions in the Notice. If you requested printed versions of these materials by mail, they will also include a proxy card for the Annual Meeting on June 18, 2024.
Important Notice Regarding the Availability of Proxy Materials for the Annual Meeting of Stockholders to be held on June 18, 2024: This Proxy Statement and our 2023 Annual Report on Form 10-K are available at https://ir.atni.com/financial-information.
This document includes several website addresses. These website addresses are intended to provide inactive, textual references only. The information on these websites is not part of this Proxy Statement.
Who Can Vote
Only stockholders of record at the close of business on April 22, 2024 are entitled to vote at the Annual Meeting. On that date, 15,454,008 shares of common stock, par value $0.01 per share (“Common Stock”), were outstanding, with each share entitled to one vote. If your shares are registered with our transfer agent directly in your name, you are considered the stockholder of record with respect to those shares. If your shares are held in a brokerage account or by a bank or other holder of record, you are considered the beneficial owner of those shares. As a beneficial owner, you may direct your broker or other holder of record on how to vote your owned shares by following their instructions.
Voting
You may vote your shares held of record either by attending the meeting and voting in person or by proxy. To vote in person, you must attend the Annual Meeting. You do not need to register in advance to attend the Annual Meeting. On April 29, 2024, we mailed the Notice to stockholders, unless they requested printed copies of our proxy materials. The Notice contains instructions on how to access our proxy materials and how to vote. You may submit your proxy over the Internet or by telephone prior to the Annual Meeting, or, if you requested printed copies of our proxy materials, by completing, dating and returning a proxy card. Please review the instructions on the Notice or on the proxy card regarding your voting options. Any proxy that is voted according to the instructions included in the Notice or on the proxy card will be voted in the manner instructed by the stockholder, and if no instructions are given, the shares represented thereby will be voted by the proxy holders as follows:
•
FOR the election of the director nominees named herein;
​
•
FOR an advisory vote to approve the compensation of our named executive officers;
​
1

TABLE OF CONTENTS​​​
•
FOR the ratification of the appointment of PricewaterhouseCoopers LLP as our independent auditor; and
​
•
in accordance with the judgment of the proxy holders named on the proxy as to any other matter that is properly brought before the Annual Meeting, or any adjournments or postponements thereof.
​
If you hold your shares through a bank, broker or other nominee, the bank, broker or other nominee will give you separate instructions for voting your shares. Telephone and Internet voting will also be offered to stockholders owning shares through certain banks and brokers. You must make arrangements with your bank, broker or other nominee in advance of the Annual Meeting to vote your shares in person.
Quorum
The holders of a majority of the outstanding shares of Common Stock entitled to vote at the Annual Meeting, whether present in person or represented by proxy, will constitute a quorum for the transaction of business at the Annual Meeting. If a quorum is not present at the Annual Meeting, the stockholders present may adjourn the Annual Meeting from time to time, without notice, other than by announcement at the meeting, until a quorum is present or represented. At any such subsequent meeting at which a quorum is present or represented, any business may be transacted that might have been transacted at the original meeting. Abstentions and broker non-votes will be counted for purposes of determining whether a quorum is present at the Annual Meeting.
Votes Required
Proposal 1, the election of each director nominee, requires the affirmative vote of a majority of the votes cast and entitled to vote at the Annual Meeting regarding such director nominee’s election. Abstentions and broker non-votes are not considered votes cast for the foregoing purpose and will have no effect on the election of the director nominees. A broker non-vote occurs when a bank, broker or other nominee cannot vote a customer’s shares registered in the bank’s, broker’s or other nominee’s name because the customer did not send instructions on how to vote on the matter and the bank, broker or nominee is prohibited by law or stock exchange regulations from exercising its discretionary voting authority in the particular matter. Banks, brokers and other nominees will not be entitled to vote a customer’s shares in their discretion on Proposal 1.
Proposal 2, the advisory vote on the compensation of our named executive officers, requires the affirmative vote of a majority of the shares present, or represented by proxy, and entitled to vote on the matter. Abstentions will be considered to be votes present and entitled to vote on this proposal and, therefore, they will have the effect of a vote against this proposal. Banks, brokers and other nominees will not be entitled to vote a customer’s shares in their discretion on Proposal 2, however, such broker non-votes will have no effect on Proposal 2.
Proposal 3, the ratification of the appointment of PricewaterhouseCoopers LLP as our independent auditor for 2024 requires the affirmative vote of a majority of the shares present at the Annual Meeting, or represented by proxy, and entitled to vote on the matter. Abstentions will be considered to be votes present and entitled to vote on this proposal and, therefore, they will have the effect of a vote against this proposal. Banks, brokers and other nominees will be entitled to vote a customer’s shares in their discretion on Proposal 3, so there will be no broker non-votes on Proposal 3.
Revocability of Proxies
A proxy may be revoked at any time before it is exercised by delivering a written revocation to ATN International, Inc., Attn: Secretary, 500 Cummings Center, Suite 2450, Beverly, MA 01915. A proxy may also be revoked by re-voting by Internet or by telephone as instructed on your Notice or proxy card, as applicable, or by voting in person at the Annual Meeting. If you hold your shares through a bank, broker or other nominee, you must make arrangements with your bank, broker, or other nominee to revoke your proxy.

Where Can I Find the Voting Results of the Annual Meeting?

Solicitation Expenses
This solicitation is being made by us and as such, we will bear all costs of solicitation of proxies.

In addition to solicitations by mail, our directors, officers and regular employees, without additional remuneration, may solicit proxies by telephone, e-mail, facsimile and personal interviews. We will request brokers, banks, and other holders of record to forward proxy soliciting material to beneficial owners.

TABLE OF CONTENTS​​​
PROPOSAL 1: ELECTION OF DIRECTORS
Stockholders are being asked to elect the following eight members to our Board to hold office until our next annual meeting of stockholders or until their respective successors are elected and qualified, subject to their earlier retirement, resignation or removal:
Bernard J. Bulkin
Richard J. Ganong
April V. Henry
Derek G. Hudson
Patricia A. Jacobs
Pamela F. Lenehan
Brad W. Martin
Michael T. Prior
Each nominee has consented to his or her nomination and is expected to stand for election. However, if any nominee is unable or unwilling to serve, proxies will be voted for a replacement candidate nominated by our Board. Biographical information for each of the nominees is set forth below under “Director and Nominee Experience and Qualifications.”
Vote Required
Each director nominee must be elected by an affirmative vote of a majority of the votes cast at the Annual Meeting and entitled to vote on such director nominee’s election. Abstentions and broker non-votes will not be treated as votes cast and, therefore, will not affect the outcome of the elections.
If a director nominee does not receive a majority of the votes cast regarding his or her election, such nominee will be required to submit an irrevocable resignation to the Nominating and Corporate Governance Committee of the Board, and the committee will then make a recommendation to the Board as to whether to accept or reject the resignation or whether other action should be taken. The Board will then act on the resignation, taking into account the committee’s recommendation, and we will publicly disclose (by filing an appropriate disclosure with the SEC) the Board’s decision regarding the resignation within 90 days following certification of the election results. The Nominating and Corporate Governance Committee in making its recommendation, and the Board in making its decision, each may consider any factors and other information that they consider appropriate and relevant.
Recommendation of our Board of Directors
OUR BOARD UNANIMOUSLY RECOMMENDS THAT STOCKHOLDERS VOTE FOR THE ELECTION OF EACH OF THESE NOMINEES.

PROPOSAL 2: ADVISORY VOTE ON EXECUTIVE COMPENSATION
The Board is providing stockholders with the opportunity to cast an advisory vote on the compensation of our named executive officers as described in the Compensation Discussion and Analysis, the compensation tables and related materials contained in this Proxy Statement. This proposal, also commonly referred to as a “Say on Pay” vote, gives our stockholders the opportunity to indicate whether they approve of or do not approve of our executive compensation policies and programs and the compensation actually paid to our named executive officers. This resolution is required pursuant to Section 14A of the Securities Exchange Act. We currently provide our stockholders the opportunity to indicate whether they approve of the compensation of our named executive officers annually.
Please review the Compensation Discussion and Analysis beginning on page 28 and the accompanying tabular and other disclosures on executive compensation beginning on page 39, and cast a vote either to endorse or not endorse our executive compensation program. A vote “For” this proposal is an advisory vote approving the compensation of our named executive officers, including our compensation practices and principles and their implementation, as discussed and disclosed pursuant to the Securities and Exchange Commission’s compensation disclosure rules in the Compensation Discussion and Analysis, the compensation tables, and any narrative executive compensation disclosure contained in this Proxy Statement.
The Compensation Committee and the Board believe our executive compensation programs use appropriate structures and policies that are effective in achieving our Company goals and objectives. Accordingly, the Board recommends that you vote in favor of the following resolution:
“RESOLVED, that the stockholders approve of the compensation of the Company’s named executive officers, as disclosed in the Compensation Discussion and Analysis and Executive Compensation sections contained in this Proxy Statement.”
The Say on Pay vote is advisory in nature, and therefore, it is not binding on our Compensation Committee or Board. Although the vote is non-binding, our Compensation Committee will review the voting results, seek to determine the cause or causes of any significant negative voting, and take them into consideration when making future decisions regarding executive compensation programs.
Required Vote
The approval, on an advisory and non-binding basis, of the compensation of our named executive officers requires the affirmative vote of a majority of the shares present, or represented by proxy, and entitled to vote thereon. Abstentions will be considered to be votes present and entitled to vote on this proposal and, therefore, they will have the effect of a vote against this proposal. Banks, brokers and other nominees will not be entitled to vote a customer’s shares in their discretion on this proposal, however, such broker non-votes will have no effect on Proposal 2.
Recommendation of our Board of Directors
OUR BOARD RECOMMENDS THAT YOU VOTE FOR APPROVAL OF THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS AS DISCLOSED IN THIS PROXY STATEMENT.

PROPOSAL 3: RATIFICATION OF SELECTION OF INDEPENDENT AUDITOR
The Audit Committee of our Board has selected PricewaterhouseCoopers LLP as our independent auditor to perform the audits of our financial statements and of our internal control over financial reporting for the fiscal year ending December 31, 2024. In making its selection, the Audit Committee conducted a review of PricewaterhouseCoopers LLP’s performance, including consideration of the following:
•
PricewaterhouseCoopers LLP’s performance on the audits, including the quality of the engagement team and the firm’s experience, client service, responsiveness and technical expertise;
​
•
The record of the firm against comparable accounting firms in various matters such as regulatory, litigation and accounting matters;
​
•
The firm’s financial strength and performance; and
​
•
The appropriateness of fees charged by the firm.
​
PricewaterhouseCoopers LLP was our independent auditor for the year ended December 31, 2023.
The Board recommends that stockholders ratify the selection of PricewaterhouseCoopers LLP as our independent auditor. Although ratification is not required by our bylaws or otherwise, the Board is submitting the selection of PricewaterhouseCoopers LLP to our stockholders for ratification as a matter of good corporate practice. If the selection is not ratified, the Audit Committee will consider whether it is appropriate to select another independent auditor. Even if the selection is ratified, the Audit Committee in its discretion may select a different independent auditor at any time during the year if it determines that such a change would be in the best interests of the Company and our stockholders.
Vote Required
The ratification of the appointment of PricewaterhouseCoopers LLP as our independent auditor for 2024 requires the affirmative vote of a majority of the shares present, or represented by proxy, at the Annual Meeting and entitled to vote thereon. Abstentions will be considered to be votes present and entitled to vote on this proposal and, therefore, they will have the effect of a vote against this proposal. Banks, brokers and other nominees will be entitled to vote a customer’s shares in their discretion on this proposal, so there will be no broker non-votes on this proposal.
Recommendation of our Board of Directors
OUR BOARD UNANIMOUSLY RECOMMENDS THAT STOCKHOLDERS VOTE FOR THE RATIFICATION OF THE SELECTION OF THE INDEPENDENT AUDITOR FOR 2024.

CORPORATE GOVERNANCE
General
The role of the Board is to ensure that we are managed for the long-term benefit of our stockholders. The Board periodically reviews and advises management with respect to our annual operating plans and strategic initiatives. The Board has adopted corporate governance principles to support compliance with all applicable corporate governance standards.
During the past year, we have reviewed our corporate governance practices in comparison to the practices of other public companies and to ensure they comport with guidance and interpretations provided by the SEC and the Nasdaq Stock Market (“Nasdaq”).
We have a written Code of Ethics that applies to all of our employees and agents, including, but not limited to, our principal executive officer, principal financial officer and principal accounting officer, or persons performing similar functions. Our Code of Ethics, Nominating and Corporate Governance Committee Charter, Compensation Committee Charter, Investment Committee Charter, and Audit Committee Charter are available on our website at https://ir.atni.com/ and may be obtained free of charge upon request by writing to us at ATN International, Inc., Attn: Secretary, 500 Cummings Center, Suite 2450, Beverly, MA 01915.
Board Leadership Structure
Our Board is committed to maintaining responsible and effective corporate governance and is focused on the interests of our stockholders. Our Board brings strong leadership and industry expertise to inform the management and direction of the Company on behalf of our stockholders. Management and the Board work together to focus the Board on questions of governance, succession and setting the Company’s overall operating and investment strategy.
Mr. Michael Prior has served as a member of our Board since June 2008 and as Chairman of our Board since 2018, the Nominating and Corporate Governance Committee intends to nominate him to continue to serve in the role of Chairman for the 2024 year, assuming he is re-elected to the Board. Effective January 1, 2024, Mr. Prior was appointed to serve as Executive Chairman and stepped down from his role as Chief Executive Officer of the Company, a position he held since 2005. In his role as Executive Chairman, Mr. Prior provides advice and guidance to Mr. Martin, our newly appointed Chief Executive Officer, and serves as a resource to other members of management with respect to ongoing items, including government relations and corporate development.
The Audit, Compensation, and Nominating and Corporate Governance Committees of the Board, are chaired by, and entirely composed of, independent directors, a policy that the Board determined best serves the Company and its stockholders. The Board does not have a policy regarding the separation of the roles of Chairman of the Board and Chief Executive Officer, as the Board believes it is in the best interests of the Company and our stockholders to make the determination as to who will serve as Chairman based on an assessment of the current needs of the Company and composition of the Board.
As the Chief Executive Officer and Chairman were combined in 2018, the Board had determined at that time to appoint a Lead Independent Director. In 2022, Dr. Bernard J. Bulkin was appointed by the Board as the Company’s Lead Independent Director to serve for a term of up to three years, assuming his re-election to the Board each year. The Lead Independent Director is an independent, non-employee director designated by the Board to serve in a lead capacity to coordinate the activities of the other non-employee directors, interface with and advise management, and perform such other duties as the Board may determine. Although the Board does not have a firm policy regarding the requirement to appoint a Lead Independent Director, it currently believes that in light of the fact that the Chairman is not considered independent, it is appropriate for the Board to continue to have a Lead Independent Director. The Board’s expectations for this role is as follows or as otherwise deemed necessary or desirable by the independent directors:
•
to convene and chair meetings of independent directors at least annually or as otherwise deemed necessary or desirable by the independent directors;
​
15

TABLE OF CONTENTS​
•
to offer input to the Executive Chairman in setting the agenda for Board meetings; and
​
•
to serve as a sounding board and spokesperson for independent directors for any board or stockholder related matters, as appropriate.
​
Director Nomination Process
Our Nominating and Corporate Governance Committee considers director nominees, whether proposed by a stockholder or identified through the Company’s processes, in accordance with its charter and our Corporate Governance Guidelines (as posted on our website). The Nominating and Corporate Governance Committee does not rely on a prescribed set of qualifications for director nominees but applies general criteria intended to ensure that the Board includes members with significant breadth of experience, knowledge and abilities as well as financial and industry expertise to assist the Board in performing its duties. Minimum qualifications for director nominees include:
•
Nominees should have a reputation for integrity, honesty and adherence to high ethical standards;
​
•
Nominees should have demonstrated business acumen, experience and the ability to exercise sound judgment in matters that relate to the current and long-term objectives of the Company, and should be willing and able to contribute positively to the decision-making process of the Board;
​
•
Nominees should have a commitment to understanding the Company and its industries and to regularly attending and participating in meetings of the Board and its committees;
​
•
Nominees should have an interest in and be capable of understanding the sometimes conflicting interests of the various constituencies of the Company, which include stockholders, employees, customers, governmental units, creditors and the general public, and to act in the interests of stockholders; and
​
•
Nominees should not have, nor appear to have, any conflicts of interest that could impair the nominee’s ability to represent the interests of all of the Company’s stockholders and to fulfill the responsibilities of a director.
​
The re-nomination of existing directors is based on continuing qualification as determined by our Nominating and Corporate Governance Committee. This Committee evaluates the performance of existing directors and any applicable committees based on the results of the Board’s annual self-assessment process as well as the extent to which the directors undertook continuing education related to the Company’s industry and operating environment. Our Board requires that the backgrounds and qualifications of the directors considered as a group provide a significant breadth of experience, knowledge and abilities that assist the Board in fulfilling its responsibilities. In determining the array of skills and attributes relevant to the Company,
16

TABLE OF CONTENTS​
the Nominating and Corporate Governance Committee maintains a matrix of all skills and attributes represented by current directors and director nominees, each of which fit into the categories as summarized below:

​ | ​ | Senior leadership experience. Directors who have held significant corporate leadership positions bring valuable knowledge of organization, controls, strategy and risk management, and can provide insight as to how to drive change and growth. Our skills matrix also tracks past and current director roles on other corporate boards and committees, ensuring we have the right mix of experience to advise and oversee the Company’s executive management. | ​ | ​ | ​ | Finance experience. We believe that as a public company, our directors must have an understanding of our financial reporting processes, risk management policies, and the way we measure and analyze our operating and strategic performance by reference to financial goals. Our current slate of director nominees includes several directors who qualify as an “audit committee financial expert” as defined in applicable SEC rules, and we expect all of our directors to be financially knowledgeable. | ​ | ​
​ | ​ | Industry experience. We endeavor to have some directors with experience as executives, directors or in other leadership positions in the industries in which we operate and target for growth. For example, we specifically seek directors with experience in the telecommunications industry. | ​ | ​ | ​ | Board Tenure. We endeavor to vary the tenure of the directors on our Board, which we believe allows us to preserve continuity of oversight while introducing new insights to our group. To accomplish this, our Board engages in succession planning with respect to its current slate of directors and seeks to maintain a roster of prospective Board nominees in the near- and mid-term. Our director nominees currently have an average tenure of 4.8 years. | ​ | ​
​ | ​ | Global business / International Affairs. Due to the global nature of our business, we seek directors who have leadership or oversight experience with other companies with a global presence. We believe that an understanding of the differences in global culture and perspective strengthen our Board’s ability to understand our business and advise management accordingly. | ​ | ​ | ​ | Governmental and Regulatory Affairs. The telecommunications industry is highly regulated in each of the jurisdictions in which we operate, and we seek directors who are familiar with working through a legal or regulated environment or who can advise management on navigating through key governmental relationships in operating the business. | ​ | ​

Board Refreshment
Our Board has undergone significant change as part of a conscious effort, led by the Nominating and Corporate Governance Committee, to refresh the Board and augment its composition with fresh, diverse perspectives and complementary skills and experiences that are aligned with the Company’s long-term strategy.
17

TABLE OF CONTENTS
Since 2017, many of our long-tenured directors have stepped down and our Board has added many new directors, and those new directors comprise the majority of the directors of the Board.
The graphics below illustrate the efficacy of our Board refreshment over time:

Reflects the characteristics of Director candidates in each of the years shown.
​
In selecting director nominees, pursuant to our Corporate Governance Guidelines, our Nominating and Corporate Governance Committee considers candidates submitted by stockholders and evaluates such candidates in a similar manner and using the same criteria as all other director nominee candidates. The Nominating and Corporate Governance Committee seeks to align the skills and key expertise of each board member or candidate identified in the board assessment process to the current or future needs of the Company according to its strategy. In doing so, the Nominating and Corporate Governance Committee has utilized a practice of assembling and reviewing a board skills matrix in its succession planning, similar to as provided below:
18

TABLE OF CONTENTS
In addition to the qualifications and considerations set forth above, in considering candidates for nomination to recommend to the full Board, our Nominating and Corporate Governance Committee also is mindful of the requirements of Nasdaq and the SEC that a majority of the Board be composed of “independent” directors. As part of its director succession and candidate recruitment process, in addition to considering director candidates referred by existing board members and advisors, the Nominating and Corporate Governance Committee has also benefitted from referrals from organizations, such as Boston Women’s Leaders Network seeking to connect experienced, high potential board candidates with public companies. Prior to making any nomination, our Nominating and Corporate Governance undergoes a rigorous review of a candidate’s background, and requests that each candidate engages in several in-person meetings with our Chairman as well as the Chair and other members of our Nominating and Corporate Governance Committee, and typically conducts a background check. Our Nominating and Corporate Governance Committee then recommends director nominees to the Board for its consideration.
To submit a director nominee candidate, stockholders should submit the following information: (a) the candidate’s name, age and address, (b) a brief statement of the reasons the candidate would be an effective director, (c) the candidate’s principal occupation or employment for the past five years and information about any positions on the board of directors of other companies held by the candidate, (d) any business or other significant relationship the candidate has had with us and (e) the name and address of the stockholder making the submission. Nominees will not be discriminated against on the basis of race, religion, national origin, gender, sexual orientation, disability or any other basis proscribed by law.
All submissions of director nominee candidates made by stockholders should be sent to ATN International, Inc., Attn: Nominating and Corporate Governance Committee, 500 Cummings Center, Suite 2450, Beverly, MA 01915 and must comply with applicable timing requirements. Our Nominating and Corporate Governance Committee may also seek additional information regarding the director nominee candidate and the stockholder making the submission. In considering candidates recommended by
19

TABLE OF CONTENTS​​
stockholders, our Nominating and Corporate Governance Committee will take into consideration the needs of the Board and the qualifications of each candidate. When assessing new director candidates for nomination, regardless of who recommends the candidate for consideration, the Nominating and Corporate Governance Committee will consider the skills, business and board experience, background, diversity, and personal characteristics of the candidate. For a more detailed description of the attributes considered see “Director Nomination Process” above.
Stockholders may also nominate candidates to the Board pursuant to the advance notice, information, and consent provisions contained in our Bylaws. See the “Stockholder Proposals for 2025 Annual Meeting” section of this Proxy Statement on page 52 for more information.

Nasdaq rules require that a majority of our directors be “independent” and that we maintain a minimum three-person audit committee and a two-person compensation committee whose members satisfy heightened independence requirements. Pursuant to Nasdaq rules, independence is evaluated using both a subjective test and various objective standards, such as that the director is not an employee of the Company. Under the subjective test, a director qualifies as “independent” if our Board, upon the recommendation of our Nominating and Corporate Governance Committee and after evaluating the objective standards referenced above, affirmatively determines that the director does not have a relationship with us, an affiliate of ours, or otherwise that, in the opinion of the Board, would interfere with the exercise of independent judgment in discharging his or her duties as a director.
Our Nominating and Corporate Governance Committee and the Board have determined that as of January 1, 2024 all of our current directors and director nominees, with the exception of Messrs. Martin and Prior, are independent for purposes of applicable SEC and Nasdaq rules. Mr. Prior previously was our Chief Executive Officer and Chairman, but he stepped down from his position as Chief Executive Officer of the Company effective December 31, 2023 and is now our Executive Chairman. Mr. Martin is our current CEO.
Risk Management and Risk Assessment
Our Audit Committee has primary responsibility for the oversight of risk management and risk assessment, including the Company’s major financial risk exposures, business continuity risks, cybersecurity risks, environmental risks and the steps management has undertaken to control such risks. For more information on ATN’s cybersecurity risk management and strategy, and cybersecurity governance please reference ITEM 1C. CYBERSECURITY in our Annual Report on Form 10-K as filed with the SEC on March 15, 2024.
Our Board remains actively involved in such oversight of risk management and assessment and receives periodic presentations from our executive officers and certain of their direct reports, as the Board may deem appropriate. This includes discussions of the Company’s balance sheet and capital structure in light of potential capital needs and projections of operating cash flows and the risks to such cash flows. While the Board maintains oversight responsibility, management is responsible for the day-to-day risk management processes and makes detailed recommendations on sources and uses of capital. The Board believes this division of responsibility is the most effective approach for addressing the risks facing the Company. As a general matter, management and the Board seek to mitigate major risks to the Company’s financial condition by striving to maintain a level of debt to annual operating cash flows that allows the Company to survive short-term unforeseen reductions in cash flow or unanticipated large capital spending needs.
For the year ended December 31, 2023, the Compensation Committee, in consultation with the Chairman and CEO, reviewed the Company’s compensation policies and practices for employees generally as they relate to risk management. As part of this process, the Compensation Committee reviewed the Company’s cash and equity incentive compensation plans and practices applicable to all employees to determine whether such programs create incentives that might motivate inappropriate or excessive risk-taking. In the course of such review, the following mitigating features of the Company’s incentive compensation programs were considered: (i) the Company’s focus on multiple year vesting periods for all equity compensation, including the restricted stock unit awards made for 2023 achievements;
20

TABLE OF CONTENTS​​
(ii) management’s practice of prudent awards of annual cash bonus payments; and (iii) the use of restricted stock unit and performance stock unit awards to encourage management to balance “upside” and “downside” risk by including both time-based and performance-based vesting. While the Compensation Committee did not identify changes to its compensation programs specifically needed to mitigate risk, the Compensation Committee also determined this year to introduce performance-based vesting for a number of restricted stock units that are intended to further align the compensation of the Company’s senior management with stockholder returns over a multi-year period. For more information about the Company’s award of performance stock units, please see “Executive Compensation—Compensation Discussion and Analysis—Annual Cash and Equity Bonus.”
Communications with Stockholders and Other Interested Parties
Our Board and management team may from time to time meet with or conduct outreach to our investors to enhance our understanding of their perspective regarding our performance and governance matters. In addition to the typical activities to reach out to existing and prospective investors in the Company, in 2023 and early 2024, members of management and the Board also reached out to the governance specialists at several of the large index funds holding shares in the Company to understand their positions on governance and other matters. The Board values the feedback provided during these engagements, which it has taken under advisement.
To communicate with our Audit Committee regarding issues or complaints about questionable accounting, internal accounting controls or auditing matters, contact the Audit Committee by writing to Audit Committee, ATN International, Inc., 500 Cummings Center, Suite 2450, Beverly, MA 01915.

Board of Directors’ Meetings and Committees
During 2023, our Board met seven times. In 2023, no director attended fewer than 75% of the meetings of the Board and the meetings of the committee(s) on which he or she served. Although we do not have a policy requiring our directors to attend the Annual Meeting, all of our then-current directors nominated for re-election at this year’s Annual Meeting attended last year’s annual meeting of stockholders.

This year, the Compensation Committee again retained Compensia, Inc. (“Compensia”), a compensation consultant, to re-evaluate and make recommendations as to the Company’s peer group as well as to consult on executive and director compensation trends. Following this review, the Chief Executive Officer typically meets with the Chair of the Compensation Committee to discuss the draft compensation recommendations, performance analysis and future objectives of each of the executive officers of the Company and finalizes, with input from the Chair, a memorandum detailing the Company’s performance and individual executive officer performance for the year before providing it to the full Compensation Committee. The Chief Executive Officer also engages in a detailed discussion of the performance of an executive officer or a manager of the Company’s key operating units with the Committee. The Compensation Committee has been authorized by the Board to delegate to the Chief Executive Officer the power to make limited awards under the Company’s 2023 Equity Incentive Plan (the “2023 Equity Plan”) to employees of the Company. Our Board and our Nominating and Corporate Governance Committee have determined that each of the current members of our Compensation Committee is independent under applicable Nasdaq and SEC rules for compensation committee members.
The Compensation Committee determines the compensation of the Chief Executive Officer in an executive session following its review of the Chief Executive Officer’s performance against his goals for the year, the growth and performance of the Company, his leadership skills for the previous year, his self-evaluation for the prior year’s performance, and any other relevant factors.

TABLE OF CONTENTS​​
EXECUTIVE OFFICER COMPENSATION
Compensation Discussion and Analysis
Our Compensation Committee has responsibility for establishing, implementing and maintaining the compensation program for our executive officers. For the purposes of this Compensation Discussion and Analysis, “named executive officers” and “executives” refers to the individuals who served as our Chief Executive Officer and Chief Financial Officer during the fiscal year ended December 31, 2023, as well as the other individuals included in the Summary Compensation Table below.
Compensation Philosophy
The primary objective of our executive compensation program is to attract, retain and reward executive officers who contribute to our long-term success and to maintain a reasonably competitive compensation structure as compared with similarly situated companies. We seek to align compensation with the achievement of business objectives and individual and Company performance. The annual cash bonus opportunity together with equity compensation that we provide our executive officers are our main incentive compensation tools to accomplish this alignment, as described below.
A core principle of our compensation philosophy to date is that a successful compensation program requires the application of judgment and subjective determinations of individual performance. With respect to our annual cash bonus opportunity, while we do assign an indicative weight to individual and general Company performance in determining an executive officer’s compensation, our Compensation Committee considers a number of factors in addition to these measures and we do not apply a strictly formulaic or mathematical approach to our compensation program.
The Compensation Committee does take into consideration certain financial and operational goals and metrics in determining annual cash performance bonus payments and seeks to link executive compensation actually paid to the Company’s actual performance. For bonus payments awarded to executive officers for 2023 performance, the Compensation Committee focused primarily on annual financial performance as compared to (i) the prior year, (ii) management goals and (iii) the Company’s guidance provided to the market. Key financial metrics examined included revenue, Adjusted EBITDA, Adjusted EBITDA margin and capital expenditures, with the committee considering Adjusted EBITDA performance to be the most important. The Committee also looked at other factors outside the financial results for the year, such as increases in high-speed data subscribers, high-speed data homes passed, and mobile subscribers, the refinancing of the Company’s main loan facility and certain multi-year strategic initiatives. The Compensation Committee seeks to align the metrics it reviews and considers with respect to compensation awards with those that the Board believes should lead to a sustainable increase in stockholder value.
In determining annual equity grants, the Compensation Committee looks at a number of factors including an executive’s compensation history, individual and Company performance, and internal and external equity pay levels (using the Company’s peer group listed below). Historically, even in years of financial metric outperformance, the Committee has set executive equity and “total” ​(all cash and equity compensation) compensation between the 25 th-50 th percentile of peers. For example, in recent years, the total compensation of the Company’s Chief Executive Officer has been at or below the 25th percentile of peers.
In 2021, after reviewing the practices of the Company’s peers and the broader market, the Compensation Committee decided to introduce performance-vested stock units as an element of long-term incentive compensation for executive officers. At the same time, the Compensation Committee decided to reduce awards of strictly time-vested restricted stock units—both in absolute terms and as a relative portion of an executive’s total compensation potential, and split equity awards equally between time-vested restricted stock units and performance-vested stock units. The Compensation Committee believes that this change results in better alignment between executive compensation and stockholder returns and with a three-year “cliff” vesting period for the performance-vested stock units, does not encourage undue risk taking or a short-term planning horizon.
For 2023, the Compensation Committee took the same approach, and accordingly, equity grants to executive officers made in March 2024 for 2023 performance were split equally between time-vested restricted
28

TABLE OF CONTENTS
stock units and performance-vested stock units. A description of the terms of the restricted stock units and performance-vested stock units can be found in the “Annual Cash and Equity Bonuses—Annual Equity Awards” discussion on page 34 and relating to all long-term equity grants can be found in the “Grants of Plan-Based Awards” table located on page 40 of this Proxy Statement.
In determining annual changes to an executive’s base salary, excluding promotions, the Compensation Committee primarily looks at changes in the cost of living, but also examines peer group data, generally targeting the 25th to 50th percentile for base salary and cash bonus potential. In 2023, consistent with broader efforts to maintain control of costs at the Company, the Compensation Committee approved raises for the executive officers at or around 2.9%, excluding Brad Martin, who was promoted to Chief Executive Officer and received a 36.5% increase in his base salary in connection with the promotion.
With respect to other elements of compensation, our Compensation Committee retains discretion to apply its judgment to adjust and align each individual element of our compensation program with the broader objectives of our compensation program and the overall performance and condition of the Company at the time final compensation decisions are made. We believe that our relatively lean management structure, the level of communications between our Board and our senior management team and our corporate culture make this approach an effective method of determining compensation and protecting stockholder interests.
For 2023, in response to new rules issued by the Securities and Exchange Commission, the Compensation Committee also introduced compensation recoupment tools into the Company’s compensation program by adopting two compensation recoupment or “clawback” policies that are applicable to named executive officers and certain other executives of the Company. These changes were approved by the entire Board and, serve to even more closely align the Company’s actual financial performance to the compensation of its executives. A description of the terms of the Company’s clawback policies can be found in the “Executive Compensation Recoupment Program” discussion on page 37 of this Proxy Statement.
Role of Compensation Consultant
Our Compensation Committee has retained the advisory services of Compensia, a national executive compensation consulting firm. For the past seven years, Compensia has assisted the Compensation Committee with the identification of a relevant peer group and competitive market compensation data regarding the compensation of our named executive officers and directors as compared with the peer group. Compensia does not generally provide any other services to the Compensation Committee, except as may be requested from time to time with respect to specific matters and as described below.
In 2023, as it typically does every year, the Compensation Committee asked Compensia to (i) provide information on total direct compensation—including components of salary, bonus and equity with respect to the Company’s peer group, (ii) to give advice on changes to the peer group, and (iii) to review with the Compensation Committee any recent or pending changes to the rules and public company and peer trends on executive compensation, including feedback from the broader investor community on executive compensation practices. In 2023, Compensia also provided advice and support to the Compensation Committee with respect to its new equity compensation plan and in setting pay levels for its newly promoted Chief Executive Officer, its newly hired Chief Financial Officer, and the newly created position of Executive Chairman.
Compensia works at the direction of, and reports directly to, the Compensation Committee, which may replace the compensation consultant or hire additional advisors at any time. Compensia does not perform any services for the Company unless directed to do so by the Compensation Committee. Based on an analysis of the various factors set forth in the rules of the SEC, the Compensation Committee does not believe that its relationship with Compensia or the work of Compensia on behalf of the Compensation Committee have raised any conflicts of interest, and the Compensation Committee believes that Compensia is independent.
External Sources
Generally, we seek to offer executive compensation that is reasonably competitive with telecommunications companies of a similar size. Defining a relevant “peer group” for us has been historically
29

TABLE OF CONTENTS
difficult because we have the complexity and geographic diversity of large multi-national companies but have similar total revenues and market capitalization to companies that tend to be focused on a very limited geographic area and provide limited services. Nonetheless, we believe that comparisons to certain other companies can provide us with useful information regarding appropriate compensation of our named executive officers and directors.
For 2023, our Compensation Committee referred to the executive compensation paid at the following group of companies:

​ | 8x8 | ​ | ​ | Consolidated Communications | ​ | ​ | Liberty Latin America | ​
​ | Bandwidth Inc. | ​ | ​ | Echostar | ​ | ​ | Ooma | ​
​ | Brightcove | ​ | ​ | Edgio | ​ | ​ | Ribbon Communications | ​
​ | Cable One | ​ | ​ | Gogo | ​ | ​ | Shenandoah Telecommunications | ​
​ | Charge Enterprises | ​ | ​ | IDT | ​ | ​ | ViaSat | ​
​ | Cogent Communications | ​ | ​ | KORE Group | ​ | ​ | Wide Open West | ​

Our Compensation Committee believes that these companies provide it with helpful indicators of competitive executive compensation levels and pay mix because, as a group, they had the following characteristics that are similar to ours: (1) they are primarily telecommunications companies; (2) several of them have both wireless and wireline operations; (3) several of them are of similar size to the Company in terms of market capitalization, revenue, or number of employees; and (4) several have a mix of domestic and international operations. However, finding close peers for the Company is difficult because the Company’s diverse group of operations in wide-ranging international and domestic geographies adds a level of complexity above that of the Company’s single-market or single-industry peers. Our Compensation Committee regards comparisons of us to these companies as informational reference points only—as such, we did not seek to establish any firm benchmark in reference to these companies or to require changes in our executive compensation to match changes in those companies’ compensation.
Role of Chief Executive Officer in Compensation Decisions
At the end of the year, our Chief Executive Officer evaluates the performance of our other named executive officers and makes compensation recommendations to our Compensation Committee based upon those evaluations. Our Board has delegated to our Compensation Committee full discretion in its determination of the compensation to be paid to our Executive Chairman, Chief Executive Officer and our other named executive officers, including discretion to modify the recommendations of our Chief Executive Officer in determining the type and amounts of compensation paid to each named executive officer. The Compensation Committee interacts directly with the Chief Executive Officer to evaluate his performance, in addition to conducting its own independent assessment of his performance and the performance of the Company during the year.

TABLE OF CONTENTS
Elements of Compensation
Overview
Our executive compensation program is focused on three separate elements:
•
base salary;
​
•
annual cash bonuses; and
​
•
equity awards.
​
When communicating our compensation program to current and prospective executives, the Company has focused on the combination of these three elements. Other than as described below, our Compensation Committee does not have any specific policies or targets for the allocation or “pay mix” of these compensation elements.
Base Salary
We seek to set the base salary of each executive at a level that is competitive, taking into account the overall compensation history of the particular executive and our other executives and the base salaries paid by similarly situated companies for such roles. In addition to merit-based changes when warranted, our Compensation Committee generally believes that base salaries should increase annually at a rate that is generally commensurate with cost-of-living adjustments, as represented by indicators like the Consumer Price Index. In addition to merit-based changes, larger increases (or decreases) may be made based on a change in the responsibilities of the executive. Factors such as the expansion or contraction of the Company and the financial condition and prospects of the Company may also influence annual salary adjustments. From time to time, comparative market factors also may cause the Compensation Committee to make increases above or below the normal cost-of-living adjustment.
Below is a chart showing the base salary rates for 2023 and 2024 for our named executive officers, in comparison to those in effect in 2022. For 2023, the Compensation Committee decided to provide basic cost-of-living increases for all executive officers. For 2024, the Compensation Committee adjusted each of Mr. Prior and Mr. Martin’s base salaries with their changes in role to Executive Chairman and Chief Executive Officer, respectively, and provided cost-of-living increases for Ms. Mabey and Mr. Leon.

Annual Cash and Equity Bonuses
Annual Cash Bonus
We believe that a substantial bonus opportunity, as measured as a percentage of the executive’s base salary, motivates executive performance because it makes a significant amount of the executive’s overall

TABLE OF CONTENTS
compensation contingent upon individual and Company performance. Further, such approach enables the Company to avoid a higher fixed cost of annual base salaries and gives us the ability to control a major piece of compensation expense if the Company ever experiences a business reversal.
For 2023 and 2024, the annual bonus opportunity for each of our named executive officers was as follows:

Named Executive Officer | ​ | ​ | 2024 Annual Bonus Opportunity Expressed as % of Base Salary | ​ | ​ | 2023 Annual Bonus Opportunity Expressed as % of Base Salary | ​
Michael T. Prior(1) | ​ | ​ | ​ | ​ | — | ​ | ​ | ​ | ​ | ​ | 100% | ​ | ​

​
At the end of the year, the Compensation Committee makes an overall assessment of the quality of each named executive officer’s performance during the year. For named executive officers other than the Chief Executive Officer, this assessment is based largely on discussions between the Compensation Committee and the Chief Executive Officer. As noted above, the Compensation Committee interacts directly with the Chief Executive Officer to evaluate his performance, in addition to conducting its own independent assessment of his performance and the performance of the Company during the year.
Although broad performance objectives are identified at the beginning of each year as a means to align individual behavior with Company objectives, it is communicated to each executive that the Compensation Committee always has the full discretion to determine the extent to which bonuses will be paid or not, regardless of the achievement of any such objectives. For named executive officers, the actual amount of annual cash bonus awarded for 2023 was based on a review of a number of factors that are each assigned a recommended weight for each executive, which varies based on the roles and duties of each individual. In general, the Compensation Committee believes that annual bonuses should be tied to overall Company performance such as financial and operating performance and significant strategic developments (as assessed by the Compensation Committee), particularly for the most senior members of our management team, such as our Chief Executive Officer, Chief Financial Officer, and former Chief Operating Officer.
Our corporate performance has historically been reviewed by reference to year-over-year consolidated Company performance and our Compensation Committee takes note of additional significant overall Company achievements or weaknesses which may or may not have impacted or been reflected in the Company’s financial or operational results. For 2023, the recommended weight assigned to each performance factor varied according to the role of each of our executive officers, and generally fell into the following ranges:
32

TABLE OF CONTENTS

Performance Factor | ​ | ​ | Range | ​ | ​ | Description | ​
Company Performance | ​ | ​ | 60-80% | ​ | ​ | Accomplishment of Company-wide goals for the year. These included financial performance such as revenue, and Adjusted EBITDA, key performance indicators like subscriber levels and specific Company objectives for a given year. | ​
Specific Individual Accomplishments | ​ | ​ | 10-30% | ​ | ​ | Individual accomplishments related to personal goals and key strategic and operational priorities, such as implementing productivity improvements in a particular department, completing major network projects, strengthening operational teams, mitigating certain risks and winning government support for major priorities. | ​
General Individual Performance | ​ | ​ | 10-15% | ​ | ​ | General assessment of the individual’s work performance through the year, including leadership, talent development and contribution to Company culture | ​

While these weight ranges are presented to the Compensation Committee by our Chief Executive Officer as a guide in connection with his assessment of our executives’ performance during the year, actual bonus awards are subject to the Compensation Committee’s discretion to increase, decrease, or disregard such amount or weight range for each performance metric based on the Compensation Committee’s review of each individual’s performance and relevant job responsibilities. For the Chief Executive Officer, the Committee generally gives higher weight to Company performance than the foregoing range indicates.
Typically, the Company has paid bonuses at levels at or below the target opportunity with the Compensation Committee treating the target bonus opportunity percentage as more of a ceiling in most years. For 2023, we paid the annual bonuses to our named executive officers described under the column entitled “Non-Equity Incentive Plan Compensation” in the Summary Compensation Table for the reasons described below.
Michael Prior, our Chief Executive Officer through December 31, 2023, was paid an annual bonus of $694,000, representing 100% of his 2023 annual target bonus opportunity. In determining the annual bonus and annual equity award for the Chief Executive Officer, the Compensation Committee considered a number of factors, including: (i) actual performance against the Company’s financial plan and against the prior year, (ii) the progress made on the Company’s three year strategy of fiber and other network upgrades and expansions, (iii) growth in high speed data and mobile subscribers, (iv) the award of a number of government subsidies to support network expansion to targeting under-served communities in the Company’s US operating areas, and (v) and other key achievements such as the re-financing of the Company’s main credit facility. For 2023, for the then-Chief Executive Officer and Chief Financial Officer, the Committee also took into consideration the work around ensuring a successful transition of their roles to their respective successors.
Justin Benincasa, our Chief Financial Officer through March 17, 2024, was paid an annual bonus of $315,000 or 100% of his 2023 annual target bonus opportunity. The Compensation Committee noted, among other things, in recognizing his performance for the 2023 year: (i) the successful re-financing of debt facilities and (ii) his work towards certain cost reduction actions at the Company.
Brad Martin, our Chief Operating Officer through December 31, 2023 and Chief Executive Officer effective January 1, 2024, was paid an annual bonus of $288,750, or 100% of his annual bonus opportunity for 2023 in his role of Chief Operating Officer. Among other things, the Compensation Committee considered: (i) his operational leadership of the execution of several major projects, (ii) his role in ensuring leadership transitions at several critical subsidiaries, and (iii) his increased responsibilities in the year in transitioning to his upcoming role as Chief Executive Officer.
Mary Mabey, our Senior Vice President and General Counsel, was paid an annual bonus of $172,545, or 86% of her 2023 annual target bonus opportunity, reflecting her work leading internal and external legal teams on a number of major initiatives including strategic integration, oversight and closure of large commercial contracts, and also took into consideration certain other matters not optimally executed.

TABLE OF CONTENTS
Justin Leon, Senior Vice President of Corporate Development, was paid $126,701, or 99% of his 2023 annual target bonus opportunity, reflecting his leadership on the execution on internal strategic and financial objectives.
Annual Equity Awards
Under our 2023 Plan, we may grant stock options, restricted stock and other equity awards to our directors, consultants and employees, including our named executive officers. Awards made under the 2023 Plan may be granted subject to conditions and restrictions, including vesting requirements, achievement of performance goals and forfeiture and recapture of shares upon certain events. Our Compensation Committee, composed entirely of independent non-employee directors, grants awards to our employees under our 2023 Plan. Our Chief Executive Officer also has authority to make limited grants under the 2023 Plan to employees of the Company.
In addition to annual equity awards to our officers, from time to time we may grant significant equity compensation in connection with the hiring of named executive officers. For new hires, the awards typically are made at the next regularly scheduled Compensation Committee meeting following the hire or promotion. In March 2024, Mr. Martin’s annual equity award was increased to $1,461,322 in connection with his promotion to Chief Executive Officer in January 2024.
In general, we have awarded restricted stock and stock options with time-based vesting schedules of four years, and, in the case of vested stock options, having an exercise period of 10 years while employed by the Company. Since 2013, the majority of the equity awards granted by the Compensation Committee have been in the form of restricted stock, restricted stock units, and performance stock units and the Compensation Committee has not granted option awards to our named executive officers during that period.
In keeping with its practice initiated in 2021, the equity compensation awarded to each executive officer by the Compensation Committee in March 2024 was composed of half performance-vested stock units (based on target level of performance) and half restricted stock units. As in the past, the restricted stock units vest ratably over four years on each anniversary of the grant date. The performance-vested stock units vest after the end of the three-year performance period, with the actual number of shares to vest and be issued following vesting based on the relative returns earned by the Company’s stockholders during the performance period compared to the returns earned by the broader market of “small cap” stocks that comprise the Russell 2000 Index, as described in more detail below.
Pursuant to the terms of our performance-vested stock unit award agreement, the Company issued a target number of performance-vested stock units on March 12, 2024, with the actual number of performance-vested stock units earned to be determined by comparing the Company’s total stockholder return (“TSR”) over a three-year period ending March 12, 2027 to the total shareholder return of the Russell 2000 Index for the same period. The relative performance is calculated based on the average closing prices for the 40-day trading period immediately preceding and including each of the first and last days of the three-year performance period ending on March 12, 2027.
The actual number of shares to be issued upon vesting of the performance-vested stock units in the event the Company’s TSR for such period is greater than or equal to zero at the end of the measurement period ranges from 0% (if the Company’s TSR is in the bottom 25% of the peer group) to 150% (if the Company’s stock performance is in the top 25% of the peer group). In the event the Company’s TSR is less than zero for that period, the number of shares to be issued is capped at 100% of target regardless of the level of relative outperformance. Subject to requirements relating to continued employment with the Company through the last day of the performance period ending on March 12, 2027, and to special vesting provisions in case of a change of control, death, disability or retirement, the shares will be delivered on the date (which will be no later than March 12, 2028) that the Compensation Committee makes the determination of the Company’s performance relative to the Russell 2000 Index.
In awarding equity grants, the Compensation Committee typically reviews and approves an award based on the estimated grant date value of the award, and then determines the actual number of shares underlying such award based on the then-current share price. In keeping with its practice adopted in 2020, after noting the fairly wide swings in share prices that occurred in the weeks leading up to the equity award

TABLE OF CONTENTS
determination and similar movements in previous years, the Compensation Committee determined the number of restricted stock units (“RSUs”) and performance-vested stock units (“PSUs”) to award each recipient by reference to the average closing price for the Company’s common stock for the 20 trading days up to and including the Friday in advance of the Compensation Committee’s meeting during the subsequent week. For grants made on March 12, 2024 for 2023 performance, this amount was $34.53 per share, and for grants made on March 7, 2023 for 2022 performance, this amount was $45.13 per share. The Compensation Committee believes that this practice is a fair manner of dealing with the positive or negative impact of short term movements in the Company’s share price.
The total number of equity compensation awards and value of the awards, utilizing the 20-trading day average per share, for grants made in each of the 2024 and 2023 years to named executive officers, is set forth below. While the number of PSUs below was determined utilizing the 20-trading day average per share price referenced above, the actual grant date value of such PSUs is determined based on a Monte Carlo simulation, due to its performance vesting requirements.

​
In approving the annual cash bonus and equity incentive awards, the Compensation Committee assesses the risks associated with the adoption of these awards, including the performance measures and goals for the awards, and concluded that the equity awards described above would not be likely to encourage excessive risk taking, as the restricted stock unit awards typically vest ratably over a period of four years and the performance-vested stock unit awards have a cliff vesting period of three years. While the Compensation Committee believes it is an important policy of the Board to seek to keep the aggregate shares underlying outstanding stock options, unvested restricted stock, unvested restricted stock units, and unvested performance-vested stock units at a reasonable level in relation to our outstanding equity (calculated on a fully diluted basis), the Compensation Committee believes that equity compensation will remain a critical recruitment, retention and incentive tool, as well as furthering the alignment of stockholder and employee interests.
Retirement, Benefits and Other Arrangements
In 2008, we adopted a deferred compensation plan for our then-existing executives. This plan is intended to provide retirement income to certain of our executives, including some of our named executive officers (who were executives at the time the plan was adopted). Following Mr. Benincasa’s retirement in
35

TABLE OF CONTENTS
March 2024, Mr. Prior is the only named executive officer who is a participant in this deferred compensation plan. The plan was adopted to offset a reduction in our annual contributions to these executives’ accounts under our 401(k) retirement plan that we instituted as a result of the consolidation of our 401(k) plan with similar plans of companies that we acquired. Under this plan, we make bi-weekly credits equal to 8% of the executive’s then current base salary to an account on behalf of the executive. In addition to these quarterly credits, although we have historically not done so, we may make additional credits in our sole discretion. See the description of the deferred compensation plan under the caption Non-Qualified Deferred Compensation Plan for additional information regarding the deferred compensation plan. Executives hired after 2008 do not participate in this plan. Except for this plan, our named executive officers currently do not receive any benefits, including retirement, medical and dental, life and disability insurance, that are not also available to all of our employees.
The terms of our PSU agreements provide for continued vesting following the eligible retirement of a participant. To qualify for this continued vesting of any PSU grant, a participant must retire no earlier than six months following the date of PSU grant, must be at least 55 years of age, and must have provided at least ten years of service to the Company. In connection with his retirement in March 2024, Mr. Benincasa is eligible to continue to receive continued vesting of his PSU grants made in March 2022 and March 2023, which are scheduled to vest, respectively, in March 2025 and March 2026.
Severance Agreements
In March 2023, we entered into amended executive agreements with each of our named executive officers that provide severance benefits, and in January 2024, Mr. Martin entered into an amended executive agreement with respect to his promotion to Chief Executive Officer. These severance agreements provide each executive with severance pay upon termination as described therein in exchange for standard covenants of confidentiality, non-competition, non-solicitation and non-circumvention for a one year-period following termination and a standard release and waiver of claims. In the event of a termination by the Company without “cause” or by the executive for “good reason” and in the absence of a “change in control” ​(each as defined in the agreements), each executive would be entitled to (i) severance pay in the amount of one times his or her base salary (and in the case of our Chief Executive Officer, one and a half times his or her base salary) and (ii) COBRA continuation coverage at a rate equal to the rate paid by active employees during the twelve months following the termination (eighteen months in the case of the Chief Executive Officer). In the event of a termination by the Company without “cause” or by the executive for “good reason” within the period commencing three months prior to and ending or twelve months (eighteen months in the case of the Chief Executive Officer) following, a change in control (as defined in the amended severance agreements), such executive would be entitled to (i) severance pay in the amount of one times (and in the case of the Chief Executive Officer, one and a half times) his or her base salary, (ii) such executive’s maximum target incentive compensation for such year (and in the case of the Chief Executive Officer, one and a half times such target), excluding any eligible amounts of equity compensation, (iii) COBRA continuation coverage at a rate equal to the rate paid by active employees for the twelve months following the termination (eighteen months in the case of the Chief Executive Officer), and (iv) the immediate vesting of all restricted stock, restricted stock units, performance-vested stock units or stock options held by such executive.
Stock Ownership Guidelines
We maintain stock ownership guidelines for our executive officers and our directors to further align the interests of management and our directors with those of our stockholders. The ownership guidelines require stock ownership having a “target dollar value,” which consists of the value of common stock owned by the executive officer or director as a multiple of that executive officer’s base salary or the director’s annual cash retainer, as shown in the table below:

Position | ​ | ​ | Individual Guideline Level | ​
Chief Executive Officer | ​ | ​ | 5x annual base salary | ​
All other Executive Officers | ​ | ​ | 2x annual base salary | ​
Non-Executive Directors | ​ | ​ | 2x annual retainer | ​

36

TABLE OF CONTENTS
“Target dollar value” generally is based on the number of (i) shares of common stock and (ii) aggregate vested shares of restricted stock units and performance-vested stock units with respect to which delivery of an equivalent number of underlying shares has been deferred, in each case “beneficially owned” ​(as defined by the SEC in Rule 13d-3 promulgated under the Exchange Act) by the executive officer or director, and does not include unvested shares of restricted stock, unvested restricted stock units, performance-vested stock units, or unexercised stock options. The value is computed as of the last trading day of each fiscal year, based on the closing price of our common stock as reported on Nasdaq, rounded to the nearest 100 shares.
For the calculation of satisfaction of the guideline for non-executive directors, the value of the annual retainer includes amounts payable to such director for annual stock or cash compensation, but does not include any additional retainer paid as a result of service as a Board chair, lead independent director, committee chair or committee member.
Unless and until an executive officer or non-executive director has satisfied his or her applicable guideline level (and absent a waiver from the Compensation Committee), the executive officer or non-executive director is required to retain an amount equal to 75% of the net shares received as the result of the exercise, vesting or payment of any Company equity awards granted to the executive officer or non-executive director. “Net shares” means those shares that remain after shares are sold or withheld, as the case may be, to (i) pay any applicable exercise price for an equity award (e.g., stock options, stock appreciation rights) or (ii) satisfy any immediate withholding taxes arising in connection with the exercise, vesting or payment of an equity award (e.g., stock options, stock appreciation rights, restricted stock units, restricted stock).
All of our executive officers and directors were in compliance with the policy as of December 31, 2023, however, Messrs. Doglioli, Hudson, Leon and Martin, and Mses. Henry, Jacobs and Mabey have not yet reached the ownership guideline.
Our Insider Trading and Anti-Hedging Policy expressly states that directors, officers and employees are prohibited from engaging in “short sales” or any hedging or monetization transactions, including through the use of financial instruments such as prepaid variable forward contracts, equity swaps, collars and exchange funds.
Executive Compensation Recoupment Program
In 2023, the Company adopted two compensation recoupment policies applicable to all of our executive officers and certain other employees of the Company. The first policy, applicable only to executive officers (the “Executive Clawback Policy”), requires that, in the event the Company is required to prepare a Restatement (as defined in the Executive Clawback Policy), any excess incentive-based compensation that is received by an executive officer for the purposes of the Executive Clawback Policy during the three-year look back period and was based on erroneously reported achievement of a financial metric received be subject to recoupment. The Executive Clawback Policy is designed to satisfy applicable Nasdaq requirements and is attached as an exhibit to our Annual Report on Form 10-K.
The second policy (the “Officer Clawback Policy”), applicable to both executive and certain non-executive officers (as determined from time to time by the Compensation Committee), provides that the Committee may require the recoupment of any excess incentive-based compensation received by a covered individual during the three-year look-back in the event that the Company is required to prepare a Restatement (as defined in the Officer Clawback Policy) and the Committee determines that the covered individual engaged in misconduct related to the Restatement. In addition, the Officer Clawback Policy provides that any additional cash (which does not include salary payments) or equity compensation (including both time-based and performance-based equity awards) received by an executive or non-executive officer may be subject to recoupment, if in the determination of the Compensation Committee, such individual engaged in certain misconduct that is materially adverse to the financial condition, operations or reputation of the Company.
Each Clawback Policy is intended to supplement, but not limit or constrain, any statutory or regulatory right or obligation of the Company to recover compensation from its employees (including, without limitation,

the requirements of the Sarbanes-Oxley Act of 2002 and Section 16(b) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)).
“Say on Pay” Advisory Approval of Executive Compensation
At our 2023 Annual Meeting, stockholders voted on a non-binding and advisory basis, and the Board elected, to hold an advisory vote of stockholders to approve the compensation of our named executive officers annually, a change from the previous cadence of every three-years. At our 2023 Annual Meeting, the last Annual Meeting at which our stockholders voted on our named executive officer compensation, more than 95% of the shares present, or represented by proxy, and entitled to vote at the 2023 Annual Meeting approved our named executive officer compensation. While the approval in 2023 was advisory and non-binding in nature, the Board and Compensation Committee value the opinion of stockholders and consider this outcome as an indication that stockholders agree that our executive compensation programs use appropriate structures and policies that are effective in achieving our Company’s goals and objectives. This year, in recognition of the advisory vote of stockholders requesting an increased frequency of the “Say on Pay” vote, the Board is again requesting that stockholders vote, on an advisory basis, to approve the compensation of our named executive officers.
Compensation Committee Report
Each member of the Compensation Committee has reviewed and discussed the Compensation Discussion and Analysis with management and, based on such review and discussions, we recommended to the Board that the Compensation Discussion and Analysis be included in this Proxy Statement.

Mr. Martin, Ms. Mabey and Mr. Leon are not participants in our deferred compensation plan.
​
Effective as of December 5, 2008, we adopted a non-qualified deferred compensation plan for our then existing executive officers. This plan is intended to provide retirement income to our executive officers and was adopted to offset a reduction in our annual contributions to those executives’ accounts under our 401(k) retirement plan that we instituted as a result of the consolidation of our 401(k) plan with similar plans of companies that we acquired. Accordingly, we do not expect to add newly hired executives to this plan. Under this plan, we make bi-weekly credits equal to 8% of the executive officer’s then current base salary to an account in the plan on behalf of the executive. In addition to these bi-weekly credits, the Compensation Committee may make additional credits in its sole discretion. Credits to such executive officer’s account under the plan will be deemed to be invested in one or more investment funds selected by the executive officer. Overall investment return is dependent upon the performance of each executive officer’s selected investment alternatives. Credits will be fully vested at all times and the executive officers will have a non-forfeitable interest in the balance of their respective accounts. Benefits under the plan are payable upon a separation from service in a cash lump sum or in accordance with a fixed schedule elected by the executive officer. Distributions may be made prior to the executive officer’s separation from service only for certain financial hardship reasons. The plan is intended to be compliant with Section 409A of the Internal Revenue Code of 1986, as amended, and to constitute a non-qualified, unfunded executive benefit plan.
Potential Payments Upon Termination or Change of Control
We have entered into severance agreements with each of our named executive officers. For a description of these agreements, please see “Severance Agreements” above. The following table sets forth the estimated payments and benefits that would be provided to each of the named executive officers, upon termination or a termination following a change in control. The payments and benefits were calculated assuming that the triggering event took place on December 31, 2023, the last business day of our fiscal year.

Pay Ratio Disclosure
Pursuant to rules adopted pursuant to the Dodd-Frank Act, we have included in this Proxy Statement a reasonable estimate of the Chief Executive Officer to median employee pay ratio for 2023 annual compensation. We identified the median employee based on 2023 taxable wages for all individuals, excluding our then-Chief Executive Officer, Mr. Michael Prior, employed by us on December 31, 2023 (whether employed on a full-time, part-time, or seasonal basis). For such employees, we annualized the compensation for any full-time employees not employed for the entire 2023 fiscal year, but not for any part-time employees. Other than as set forth above, we did not make any assumptions, adjustments, or estimates with respect to taxable wages. After identifying the median employee, we calculated annual total compensation for such employee using the same methodology we use for our named executive officers as set forth in the 2023 Summary Compensation Table set forth elsewhere in this Proxy Statement. The annual total compensation of our median employee for 2023 was approximately $64,114. As disclosed in the Summary Compensation Table, our Chief Executive Officer’s annual total compensation for 2023 was $3,581,890. Based on the foregoing, our estimate of the ratio of the annual total compensation of our Chief Executive Officer to the median of the annual total compensation of all other employees was approximately 56:1.

TABLE OF CONTENTS
The foregoing calculation reflects employees located in all of the Company’s operating jurisdictions. At year end, we had approximately 1,025 employees in the United States and the United States Virgin Islands, and approximately 1,300 employees internationally, principally in Bermuda, the Cayman Islands, and Guyana, with employees and contractors in Guyana accounting for over half of our employees outside of the United States. For purposes of this calculation, we excluded four non-US employees in Canada, as they represent less than 5% of our employee population. Our estimate, using the same compensation measure of taxable wages, of the ratio of the annual total compensation of our Chief Executive Officer to the median of the annual total compensation of our United States employees (excluding the Chief Executive Officer) is 37:1.
To give some context to the median annual employee compensation, information regarding the gross domestic product (GDP) per capita for the Company’s main operating areas, as reported by The World Factbook, as published by the Central Intelligence Agency, including estimates of GDP for the most recent year available, is set forth below. This information regarding GDP per capita is deemed to be furnished and not filed.

Country | ​ | ​ | GDP per capita | ​

Pay Versus Performance Table
The SEC has adopted rules (as required by the Dodd-Frank Act) requiring disclosure of the relationship between the executive compensation actually paid and the financial performance of the Company. The below table outlines, in addition to the amounts listed in the Company’s Summary Compensation Table, the total Compensation Actually Paid (CAP) for the principal executive officer (CEO), which is the Company’s Chief Executive Officer, and the average of the total compensation actually paid for the Non-CEO Named Executive Officers (NEOs), which are the Company’s Chief Financial Officer, Chief Operating Officer, SVP and General Counsel, and SVP—Corporate Development, for the year as indicated. Additionally, the table includes the Company-Selected Measure of Adjusted EBITDA, as defined and described in more detail below.

The Board currently considers Adjusted EBITDA to be the most important financial performance measure used to link CAP of the CEO and Non-CEO NEOs to Company performance. The Company had historically defined Adjusted EBITDA as operating income (loss) before depreciation and amortization expense, transaction-related charges, one-time impairment or special charges and the gain (loss) on disposition of assets. In order to more closely align with similar calculations presented by companies in its industry, beginning with its 2023 financial results, the Company has also excluded non-cash stock-based compensation in its adjustment to derive Adjusted EBITDA and, as such, has restated its adjusted EBITDA for 2022 and 2021. The Company regularly reports on this metric to investors in its quarterly earnings releases and believes that the inclusion of these non-GAAP financial measures (and the associated reconciliations to the nearest GAAP financial measures) helps investors gain a meaningful understanding of the Company’s core operating results and enhances the usefulness of comparing such performance with prior periods. Accordingly, the Board considers Adjusted EBITDA as the best measure to track both Company performance as well as align executive compensation to such performance.
Tabular List of Important Financial Performance Measures
In addition to Adjusted EBITDA, the various metrics and other factors that the Compensation Committee considers in making executive compensation awards on an annual basis are described yearly in greater detail in “Executive Compensation—Compensation Discussion and Analysis.” The items listed below represent the most important measures the Company is currently using to link executive compensation actually paid to the Company’s actual performance, particularly cash bonus payment awards:

DIRECTOR COMPENSATION
Our Compensation Committee has the responsibility of reviewing and making recommendations to the Board regarding director compensation. We use a combination of cash and stock-based incentive compensation to attract and retain qualified directors. In setting director compensation, we consider the time demand and the requisite knowledge and expertise required for our directors to effectively fulfill their duties and responsibilities to us and our stockholders. We also consider the compensation set by our peer companies in our determination of director compensation and our director compensation is at approximately the 50 th percentile of our peer group.
2023 Director Compensation Table
The table below summarizes the compensation paid to, or earned by, our non-employee directors for the fiscal year ended December 31, 2023. Mr. Michael Prior, our Chairman and Chief Executive Officer during 2023, does not receive any compensation for his Board service beyond the compensation he received as Chief Executive Officer and now receives as Executive Chairman of the Company.

The amounts in this column reflect the grant date fair value calculated in accordance with FASB ASC Topic 718, of awards granted pursuant to our Non-Employee Directors Compensation Policy and our 2008 Equity Plan. Actual shares issued based on the average closing price for the Company’s common stock for the 20 trading days up to and including June 6, 2023. This had the effect of making the dollar value of the stock award higher than the $130,000 retainer as described below.

Retainers
For the fiscal year ended December 31, 2023, our non-employee directors received an annual retainer of $180,000 (consisting of $50,000 in cash and approximately $130,000 in stock). After noting the fairly wide swings in share prices that can occur in the weeks leading up to the equity award determination, the Compensation Committee determined the number of shares to award each non-employee director by reference to the average closing price for the Company’s common stock for the 20 trading days up to and including June 6, 2023. The Compensation Committee believes that this practice is a fair approach to deal with the positive or negative impact of short term movements in the Company’s share price. In addition to these retainers, our Lead Independent Director also received an additional annual cash retainer of $25,000 and independent members of Committees of our Board received additional annual cash payments as follows:

As an international telecommunications service provider, we strive to respect and promote human rights in all the markets in which we do business. Our Human and Labor Rights Policy is guided by the international human rights principles encompassed by The International Bill of Human Rights and the International Labor Organization’s 1998 Declaration on Fundamental Principles and Rights at Work. This policy applies to all entities that we own or in which we hold a majority interest.
Stockholder Proposals for 2025 Annual Meeting
All suggestions from stockholders are given careful attention. Proposals intended for consideration at next year’s annual meeting of stockholders, including proposals for director nominee candidates, should be sent to ATN International, Inc.; Attn: Secretary, 500 Cummings Center, Suite 2450, Beverly, MA 01915. To be considered for inclusion in our proxy materials for that meeting pursuant to Rule 14a-8 of the Exchange Act, such proposals must be received by us by December 27, 2024, and must comply with certain rules and regulations promulgated by the SEC. A stockholder who wishes to make a proposal at the 2025 annual meeting, but does not wish to have the proposal included in the proxy statement for that meeting, must give notice of the proposal to us no later than March 12, 2025, in order for the notice to be considered timely under Rule 14a-4(c)(1) of the Exchange Act.
Householding of Annual Meeting Materials
Some banks, brokers and other nominee record holders may be participating in the practice of “householding” proxy statements and annual reports. This means that only one copy of our Proxy Statement and Annual Report on Form 10-K may have been sent to multiple stockholders in your household. We will promptly deliver a separate copy of either document to you if you contact us at the following address or telephone number: Investor Relations, ATN International, Inc., Secretary, 500 Cummings Center, Suite 2450, Beverly, MA 01915, (978) 619-1300. If you want to receive separate copies of such materials in the future, or if you are receiving multiple copies and would like to receive only one copy per household, you should contact your bank, broker or other nominee record holder, or you may contact us at the above address or telephone number.
