GENERAL INFORMATION ABOUT VOTING

        This Proxy Statement is furnished in connection with the solicitation of proxies by the Board of Directors of ATN International, Inc., a Delaware corporation, for use at the 2018 Annual Meeting of Stockholders to be held on June 12, 2018, at 9:00 a.m. ET, or any adjournments or postponements thereof.

        We are mailing this Proxy Statement together with our Annual Letter to Stockholders, our Annual Report on Form 10-K for the year ended December 31, 2017 (excluding exhibits) and a proxy card or voting instruction for the Annual Meeting on or about April 30, 2018.

        Important Notice Regarding the Availability of Proxy Materials for the Annual Meeting of Stockholders to be held on June 12, 2018: This Proxy Statement and our 2017 Annual Report on Form 10-K are available at http://ir.atni.com/financials.cfm.

Who Can Vote

        Only stockholders of record at the close of business on April 20, 2018 are entitled to vote at the Annual Meeting. On that date, 15,974,800 shares of common stock, par value $.01 per share, were outstanding, with each share entitled to one vote. If your shares are registered directly in your name with our transfer agent, 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 and cast your vote. You do not need to register in advance to attend the Annual Meeting. If you choose to vote by proxy, you must complete, sign and date the enclosed proxy card and return it in the enclosed postage prepaid envelope. No postage is necessary if the proxy card is mailed in the United States. You may also vote your shares by following the "Vote by Internet" or "Vote by Phone" instructions on the enclosed proxy card. Telephone and Internet facilities for stockholders of record will be available 24 hours a day from the date of mailing through 11:59 p.m. EDT on June 11, 2018. If your proxy card or vote is received in time for voting and not revoked, your shares will be voted at the Annual Meeting in accordance with your instructions. If no instructions are indicated, the shares represented by the proxy card will be voted by the proxy holders as follows:

•

FOR the election of the director nominees named herein;



•

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 card as to any other matter that is properly brought before the Annual Meeting, or any adjournments or postponements thereof.

Table of Contents

        If you hold your shares through a bank, broker or other nominee, they 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 broker, bank 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 adjourned meeting at which a quorum is present or represented, any business may be transacted that might have been transacted at the original meeting. Abstentions, votes withheld 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.

        Proposal 2, the ratification of the appointment of PricewaterhouseCoopers LLP as our independent auditor for 2018, requires the affirmative vote of a majority of the shares present, or represented by proxy, at the Annual Meeting and entitled to vote on the matter.

        We will not count shares that abstain from voting ("abstentions") on a particular matter as votes in favor of such matter. Similarly, we will not count broker non-votes as votes in favor of such matter. A broker non-vote occurs when a broker cannot vote a customer's shares registered in the broker's name because the customer did not send the broker instructions on how to vote on the matter and the broker is prohibited by law or stock exchange regulations from exercising its discretionary voting authority in the particular matter. Accordingly, broker non-votes will have no effect on the outcome of voting on Proposal 1. Brokers will be entitled to vote a customer's shares in their discretion on Proposal 2, so there will be no broker non-votes on that proposal. However, abstentions will be considered to be votes present and entitled to vote on Proposal 2, and they will have the effect of a vote against that proposal. Inspectors of election appointed by our Board will tabulate votes.

Revocability of Proxies

        A proxy may be revoked at any time before it is exercised by delivering a written revocation or a duly executed proxy card bearing a later date 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 above 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 broker, bank or other nominee to revoke your proxy.

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

        The preliminary voting results will be announced at the Annual Meeting, and we will publish preliminary, or final results if available, in a Current Report on Form 8-K within four business days of the Annual Meeting. If final results are unavailable at the time we file the Form 8-K, then we will file an amended report on Form 8-K to disclose the final voting results within four business days after the final voting results are known.

Bernard J. Bulkin
Michael T. Flynn
Richard J. Ganong
John C. Kennedy
Liane J. Pelletier
Michael T. Prior

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 regarding 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 would be required to submit an irrevocable resignation to the Nominating and Corporate Governance Committee of the Board, and the committee would make a recommendation to the Board as to whether to accept or reject the resignation or whether other action should be taken. The Board would then act on the resignation, taking into account the committee's recommendation, and publicly disclose (by filing an appropriate disclosure with the SEC) its decision regarding the resignation within 90 days following certification of the election results. The 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 RECOMMENDS THAT STOCKHOLDERS VOTE FOR THE ELECTION OF EACH OF THESE NOMINEES.

PROPOSAL 2: RATIFICATION OF SELECTION OF INDEPENDENT AUDITOR

        The Audit Committee of our Board of Directors has selected PricewaterhouseCoopers LLP ("PwC") as our independent auditor to perform the audit of our financial statements and of our internal control over financial reporting for the fiscal year ending December 31, 2018. In making its selection, the Audit Committee conducted a review of PwC's performance, including consideration of the following:

•

PwC's performance on the audit, 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.

        PwC was our independent auditor for the year ended December 31, 2017.

        The Board of Directors recommends that stockholders ratify the selection of PwC as our independent auditor. Although ratification is not required by our bylaws or otherwise, the Board is submitting the selection of PwC 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 PwC as our independent auditor for 2018 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. Brokers 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 RECOMMENDS THAT STOCKHOLDERS VOTE FOR THE RATIFICATION OF THE SELECTION OF THE INDEPENDENT AUDITOR FOR 2018.

CORPORATE GOVERNANCE

General

        The role of the Board of Directors 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 assure full and complete 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.

        We have adopted 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 and Audit Committee Charter are available on our website at 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 of Directors 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 of Directors work together to try to focus the Board on major questions of governance, succession and setting the Company's overall investment and operating strategy.

        Mr. C.B. Prior, Jr., who has served as our Chairman since 1997, was also our Chief Executive Officer until December 2005. Mr. C.B. Prior, Jr. will be retiring from the Company's Board effective as of the date of the Annual Meeting. He, together with related entities, affiliates and family members, controls more than 30% of our outstanding common stock.

        The Board has nominated Mr. Michael Prior, our Chief Executive Officer, as our new Chairman to assume such role upon Mr. C.B. Prior, Jr.'s retirement, effective as of the date of the Annual Meeting. In prior years, the Board determined that its leadership structure, including Mr. C. B. Prior, Jr. serving as Chairman, our Chief Executive Officer serving as a director, and the composition of independent directors for each of the Audit, Compensation and Nominating and Corporate Governance Committees of the Board, best served 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. Our Board believes that combining the Chairman and Chief Executive Officer positions will align corporate strategy development with management oversight in the Board process and, taken together with the Lead Director role, is the appropriate leadership structure for us at this time. The Board determined that Mr. Michael Prior's extensive business and leadership experience made him the best candidate for Chairman.

        As the positions of Chief Executive Officer and Chairman will be combined following the Annual Meeting, the Board intends to appoint a Lead Independent Director. The Lead Independent Director shall be an independent, non-employee director designated by the Board who shall 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. While the Board does not

Table of Contents

have a policy regarding the requirement to appoint, or role of, a Lead Independent Director, it expects that such role will serve:

•

to convene and chair meetings of independent directors at each board meeting and as necessary in addition to regularly scheduled meetings;



•

as a liaison between the CEO/Chairman and the independent directors, to provide feedback from executive sessions and keep the Board informed of other matters as necessary; and



•

as a sounding board, if necessary, to the CEO/Chairman on board agenda, materials and other matters.

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 Nominating and Corporate Governance Guidelines, as currently in effect. The Nominating and Corporate Governance Committee does not rely on a fixed 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: a reputation for integrity, honesty and adherence to high ethical standards; demonstrated business acumen, experience and judgment related to the objectives of the Company; and the commitment to understand the Company and its industry and actively participate in Board deliberations. While our Board does not have a formal diversity policy, it recognizes that a diversity of backgrounds, expertise and life experience can enhance the effectiveness of the Board. Accordingly, our Nominating and Corporate Governance Committee also considers nominees based on their differences of viewpoint, professional experience, education, skill and other characteristics that are relevant to the current needs of the Company, including those that promote diversity. Our Nominating and Corporate Governance Committee then recommends director nominees to the Board for its consideration and nomination at the next annual meeting of stockholders.

        In selecting director nominees pursuant to the Nominating and Corporate Governance Guidelines, our Nominating and Corporate Governance Committee considers candidates submitted by stockholders and evaluates such candidates in the same manner and using the same criteria as all other director nominee candidates. 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, (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. Our Nominating and Corporate Governance Committee may also seek additional information regarding the director nominee candidate and the stockholder making the submission.

Determination of Independence

        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. A director qualifies as "independent" if our Board, upon the recommendation of our Nominating and Corporate Governance Committee, affirmatively determines that the director does not have a relationship with us, an affiliate of ours, or otherwise that,

13

Table of Contents

in the opinion of the Board, would interfere with the exercise of independent judgment in discharging his or her duties as a director. Nasdaq rules preclude an affirmative determination by the Board that a director is independent if:

•

a director who is, or was at any time during the past three years, employed by us or by any subsidiary of ours;



•

a director who accepted or has a family member who accepted any compensation from us or any subsidiary of ours in excess of $120,000 during any period of twelve consecutive months within the three years preceding the determination of independence, other than: (i) compensation for board or board committee service, (ii) compensation paid to a family member who is an employee (other than the executive officer) of the company, or (iii) benefits under a tax-qualified retirement plan, or non-discretionary compensation;



•

a director who is a family member of an individual who is, or at any time during the past three years was, employed by us or a subsidiary of ours as an executive officer;



•

a director who is, or has a family member who is, a partner in, or a controlling stockholder or an executive officer of, any organization to which we made, or from which we received, payments for property or services in the current or any of the past three fiscal years that exceed the greater of 5 percent of the recipient's consolidated gross revenues for that year, or $200,000, whichever is more, other than: (i) payments arising solely from investments in our securities or (ii) payments under non-discretionary charitable contribution matching programs;



•

a director who is, or has a family member who is, employed as an executive officer of another entity where at any time during the past three years any of our executive officers have served on the compensation committee of such other entity; or



•

a director who is, or has a family member who is, a current partner of our outside auditor, or was a partner or employee of our outside auditor who worked on our audit at any time during any of the past three years.

        Based on the Nasdaq rules, our Nominating and Corporate Governance Committee and the Board has determined that Messrs. Budd, Flynn and Roesslein, Dr. Bulkin, Ms. Pelletier and our director nominees who do not currently serve on our Board, Messrs. Kennedy and Ganong, are independent for purposes of SEC rules and Nasdaq listing compliance. This determination included reviewing the following relationships and transactions with Mr. Budd, which our Nominating and Corporate Governance Committee and the Board concluded did not affect his independence:

Mr. Budd.    Mr. Budd is a former partner of the law firm of Day, Berry and Howard, LLP, which is now known as Day Pitney LLP ("Day Pitney"), and had served as our general outside counsel for a number of years until his retirement on December 31, 2006. From time to time, our Chairman has engaged, in an individual capacity, Day Pitney for legal services. The Compensation Committee retained Day Pitney in 2015 to advise it on the terms and conditions of standard severance agreements for executive officers.

Nominating and Corporate Governance Committee Report

        The Nominating and Corporate Governance Committee has reviewed and discussed the Director Nomination Process and Director Independence disclosure and, based on such review and discussions, we recommended to the Board that (i) these disclosures be included in this Proxy Statement and (ii) that each of the persons listed in Proposal 1, "Election of Directors," be nominated by the Board for election as a director of the Company.

Risk Management and Risk Assessment

        In accordance with Nasdaq requirements, our Audit Committee has the primary responsibility for the oversight of risk management and risk assessment, including the Company's major financial risk exposures, cyber security risks and the steps management has undertaken to control such risks. Our Board of Directors 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 of Directors 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 of Directors maintains such 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 of Directors 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 of Directors 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. To date, the Board of Directors believes that the Company has maintained a more conservative level of debt (relative to cash flows) than most of its peers in the telecommunications industry.

        For the year ended December 31, 2017, our management, in consultation with the Board, reviewed the Company's compensation policies and practices for employees generally as they relate to risk management. As part of this process, management 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 awards made for 2017 achievements; (ii) management's practice of conservative awards of annual cash bonus payments; (iii) the relatively low level and intermittent awards of stock options to senior management; and (iv) the use of restricted stock and restricted stock unit awards to encourage management to balance "upside" and "downside" risk. As a result of this process, there were no recommended changes to the Company's incentive compensation programs.

Communications from Stockholders and Other Interested Parties

        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.

        To send communications to the Board or to individual directors, stockholders should write to Board of Directors, ATN International, Inc., 500 Cummings Center, Suite 2450, Beverly, MA 01915. All communications received will be directly sent to the Board or to individual members of our Board, as addressed.

Board of Directors' Meetings and Committees

        During 2017, our Board met four times either by conference call or in person. In 2017, no director attended fewer than 75% of the meetings of the Board or the meetings of the committee(s) on which

15

---

Table of Contents

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 attended last year's annual meeting of stockholders.

        Our Board has established three standing committees: the Audit Committee, the Compensation Committee and the Nominating and Corporate Governance Committee. The current membership of each committee is as follows:

        All members of these committees are independent as defined in the listing standards of Nasdaq.

Audit Committee

        During 2017, the Audit Committee met eight times either by conference call or in person, including several meetings without members of management or the Company's independent auditors. The functions of the Audit Committee include:

•

Appointing, compensating, evaluating and overseeing our independent auditor;



•

Reviewing with our independent auditor the plan and scope of the audit, its status during the year and any recommendations the independent auditor may have for improving or changing the audit and control environment;



•

Pre-approving the services provided by our independent auditor;



•

Overseeing the Company's internal audit department and its review and testing of the Company's internal control policies, systems and procedures;



•

Discussing with management and our independent accountant the adequacy of internal accounting and financial controls and, if deemed necessary or appropriate, discussing with each of them, independently of the other, any recommendations on matters that any of them considers to be of importance;



•

Reviewing our accounting principles, policies and practices and financial reporting policies and practices;



•

Reviewing our Code of Ethics, the Audit Committee Charter, the Internal Audit Department Charter any other relevant Company policies and the oversight of other compliance matters;



•

Reviewing and evaluating the effectiveness of the Company's risk assessment and risk management policies and processes;



•

Reviewing and, if appropriate, approving related party transactions entered into by the Company;



•

Reviewing, prior to publication or filing, our annual audited financial statements, quarterly earnings releases and the disclosures that are to be included in our reports on Form 10-Q and Form 10-K, as well as such other information as the Committee deems desirable; and



•

Undertaking other duties as assigned by our Board.

        Our Board has determined that each current member of the Audit Committee meets the financial literacy requirements of Nasdaq. It has also determined that Mr. Roesslein, who is currently the Chair of the Audit Committee and a director nominee for re-election, qualifies as an "audit committee financial expert" under the rules of the SEC and meets the financial sophistication requirements of

Nasdaq. In addition, our Nominating and Corporate Governance Committee has determined that each of the current members of our Audit Committee meet the Nasdaq and SEC standards for audit committee member independence.

Compensation Committee

        The Compensation Committee met four times during 2017, and the Chairman of the Compensation Committee consulted and met several times with the Chief Executive Officer during 2017. The Compensation Committee has also met once during 2018 to discuss 2017 compensation and bonus awards. The functions of the Compensation Committee include:

•

Reviewing and determining the compensation of our Chief Executive Officer and our other executive officers;



•

Reviewing with the Chief Executive Officer the compensation of the managers of the Company's key operating units;



•

Reviewing and discussing our Compensation Discussion and Analysis in our Proxy Statement with management;



•

Developing, administering and taking all action required or permitted to be taken by the Board under our stock-based incentive plan;



•

Reviewing and recommending to the Board the compensation of our directors;



•

Reviewing and making recommendations to the Board regarding the level, coverage, and competitiveness (based on industry data) of our compensation (including salary and bonus), incentives (both current and long-term), benefits (including profit sharing, group health coverage, disability coverage and life insurance benefits, and use of our stock in option, bonus, or appreciation arrangements), and other perquisites;



•

Retaining and working with compensation consultants or other advisors as the Compensation Committee may deem appropriate to carry out its responsibilities;



•

Reviewing the Compensation Committee Charter; and



•

Undertaking such other functions as are assigned to the Compensation Committee by the Board.

        The Compensation Committee meets several times each year to carry out these responsibilities. Early in the year, the Compensation Committee begins its analysis by reviewing the compensation trends and practices of the Company's identified peer group as well as any other entities that the Compensation Committee may deem relevant against the current compensation of the Company's Chief Executive Officer and the Company's other executive officers. This year, the Compensation Committee again retained Compensia, a compensation consultant, to re-evaluate and make recommendations as to the Company's peer group as well as consult on executive and director compensation trends. Following this review, the Chief Executive Officer typically meets with the Chairman of the Compensation Committee in order to discuss the draft compensation recommendations, performance analysis and future objectives of each of the executive officers of the Company and finalizes, with the Chairman, a memorandum detailing the Company's performance and individual executive officer performance for the year before providing it to the Compensation Committee. Upon the request of the Compensation Committee, the Chief Executive Officer may engage in a detailed discussion of the performance of an executive officer or a manager of the Company's key operating units. The Compensation Committee has been authorized by the Board of Directors to delegate to the Chief Executive Officer the power to make limited awards under the Company's 2008 Equity Incentive Plan (the "2008 Plan") to employees of the Company. Our Board and our Nominating and Corporate Governance Committee have determined that each of the current

17

Table of Contents

members of our Compensation Committee meets the independence requirements under Nasdaq and SEC standards for director independence.

        The Compensation Committee determines the compensation of the Chief Executive Officer in an executive session following its review of the CEO's performance against his goals for the year, the growth and performance of the Company, his leadership skills for the previous year, his self-analysis for the prior year's performance, and any other relevant factors.

        For further information about the Compensation Committee's practices, please see "Compensation Discussion and Analysis," under "Executive Officer Compensation," below.

Compensation Committee Interlocks and Insider Participation

        During or prior to the fiscal year ended December 31, 2017, no member of our Compensation Committee was an officer or employee of ours or our subsidiaries or, to our knowledge, had relationships requiring disclosure under the SEC rules. In making these statements, we have relied in part upon representations of those directors.

Nominating and Corporate Governance Committee

        The Nominating and Corporate Governance Committee of our Board met five times in 2017. To date, the Nominating and Corporate Governance Committee has met once in 2018 to discuss nominations for elections of directors and for committee membership on our Board. The functions of the Nominating and Corporate Governance Committee include:

•

recommending to the Board the persons to be considered for nomination for election as directors at any meeting of stockholders and the persons (if any) to be elected by the Board to fill any vacancies on the Board;



•

determining the independence of any director or director nominee to our Board;



•

recommending to the Board the directors to be appointed to each committee of the Board;



•

reviewing and making recommendations to the Board regarding any stockholder proposals submitted to the Company pertaining to Board governance and directors;



•

developing and making recommendations to the Board regarding any corporate governance policies for the Company;



•

overseeing periodic Board self-evaluations; and



•

undertaking such other functions as are assigned to the Nominating and Corporate Governance Committee by the Board.

        Our Board has determined that each of the current members of our Nominating and Corporate Governance Committee meet the Nasdaq and SEC standards for committee member independence.

INDEPENDENT AUDITOR

        PwC has audited our accounts since 2002. Our Audit Committee has appointed PwC to be our independent auditor for 2018 and we are asking stockholders to ratify this appointment in Proposal 2. The services provided by PwC in 2018 are expected to include, in addition to performing the consolidated audit, audits of certain subsidiaries; review of quarterly reports; issuance of letters to underwriters in connection with registration statements, if any, we may file with the SEC and consultation on accounting, financial reporting, tax and related matters. A representative of PwC is expected to be at the meeting and will have an opportunity to make a statement and respond to questions.

Audit Committee Pre-Approval Policy and Procedures

        In accordance with its written charter, our Audit Committee pre-approves all audit and non-audit services, including the scope of contemplated services and the related fees that are to be performed by PwC, our independent auditor. The Audit Committee's pre-approval of non-audit services involves consideration of the impact of providing such services on PwC's independence. The Audit Committee is also responsible for ensuring that any approved non-audit services are disclosed to stockholders in our reports filed with the SEC.

Audit Committee Report

        As members of the Audit Committee of the Board of Directors of ATN International, Inc., we have reviewed and discussed with management the audited financial statements of the Company as of and for the year ended December 31, 2017.

        The Audit Committee discussed with the independent registered public accountants the matters required to be discussed by Statement of Auditing Standard No. 1301.

        The Audit Committee received from PwC the written disclosures and letter required by applicable requirements of the Public Company Accounting Oversight Board regarding their communications with the Audit Committee concerning independence, discussed PwC's independence with PwC and satisfied itself as to PwC's independence.

        We have also concluded that the provision of services by PwC not related to the audit of the financial statements referred to above and to the reviews of the interim financial statements included in our Quarterly Reports on Form 10-Q for the quarters ended March 31, 2017, June 30, 2017 and September 30, 2017, was compatible with maintaining the independence of PwC.

        Based on the reviews and discussions referred to above, we have recommended to the Board of Directors that the audited financial statements referred to above be included in our Annual Report on Form 10-K for the year ended December 31, 2017.

EXECUTIVE OFFICER COMPENSATION

Compensation Discussion and Analysis

        Our Compensation Committee of the Board of Directors has responsibility for establishing, implementing and maintaining the compensation program for our executive officers. For the purposes of this Compensation Discussion and Analysis, "executive officers" and "executives" means the individuals who served as our Chief Executive Officer and Chief Financial Officer during the fiscal year ended December 31, 2017, 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 is that a successful compensation program requires the application of judgment and subjective determinations of individual performance. While we do assign an indicative weight to individual and general Company performance in determining an executive officer's compensation, we do not apply a strictly formulaic or mathematical approach to our compensation program. 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 our company at the time final compensation decisions are made. We believe that our relatively lean management structure, the level of communications between our Board of Directors and our senior management team and our corporate culture make this approach an effective method of determining compensation.

        Our Compensation Committee does consider the compensation of executive officers at other companies in order to assess the compensation that we offer our executive officers, as discussed below.

Role of Compensation Consultant

        Our Compensation Committee has retained the advisory services of Compensia, Inc. ("Compensia"), a national executive compensation consulting firm. For the past three years, Compensia has assisted us 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 to such 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.

        This past year, the Compensation Committee asked Compensia to gather peer group data, give advice on any possible changes to the peer group based on that data and update the Compensation Committee on recent or pending changes to the rules and industry trends on executive compensation.

21

---

Table of Contents

        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 the consideration of the various factors set forth in the rules of the SEC, the Compensation Committee does not believe that its relationship with Compensia and the work of Compensia on behalf of the Compensation Committee has 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 and to a lesser extent, renewable energy companies of a similar size. Defining a relevant "peer group" for us has been historically difficult because we have the complexity and geographic diversity (and attendant travel demands) 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 a useful basic check, mainly for the compensation of our named executive officers and directors.

        For 2017, our Compensation Committee adjusted our peer group and referred to the executive compensation paid at the following group of companies:

        Our Compensation Committee believed that these companies provided us 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 telecommunications or energy companies; (2) several of them have both wireless and wireline operations; (3) several of them are of similar size to the Company; 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. In addition, some of the telecommunications industry peers have much higher revenue than the Company as a whole. Our Compensation Committee regards comparisons of us to these companies as reference points only—as such, we did not seek to establish any 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 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 Chief Executive Officer and our other executive officers, including discretion to modify the recommendations of our Chief Executive Officer in determining the type and amounts of compensation paid to each 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.

Elements of Compensation

Overview

        Our executive compensation program is focused on three separate elements:

•

base salary;



•

annual cash bonuses; and



•

equity awards.

        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. In addition to merit-based changes when warranted, our Compensation Committee generally believes that base salaries should increase annually at a rate that is slightly above or below 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 the amount of 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 2017 for our named executive officers, in comparison to those in effect in 2016. For 2017, the Committee decided to provide basic cost-of-living increases for the executive officers other than for Mr. Fougere as explained below.

        On May 20, 2016, the two-year anniversary of Mr. Fougere's hiring, and as contemplated by his offer letter, the Company promoted Mr. Fougere to Executive Vice President and adjusted Mr. Fougere's base salary from $261,000 per year to $300,000 per year for 2016. Mr. Fougere's salary displayed above takes into effect this mid-year adjustment and the annualized percent increase displayed above shows the increase above his base salary received after his promotion. As previously disclosed, Mr. Fougere departed from his position as Executive Vice President, Business Operations, effective April 13, 2018. Mr. Brad Martin was appointed as Executive Vice President, Business Operations, effective April 30, 2018.

        As previously disclosed, Mr. Slap departed from his position as Senior Vice President and General Counsel, effective March 16, 2018. Ms. Mary Mabey, formerly our Deputy General Counsel, was appointed as Senior Vice President and General Counsel of the Company, effective March 21, 2018.

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 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 2017, the annual bonus opportunity for our named executive officers was as follows:

        At the end of the year, the Compensation Committee makes an overall assessment of the quality of each executive officer's performance during the year. For 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. For 2017, the target amounts of the bonuses, other than with respect to Mr. Fougere as a result of his 2016 promotion, were unchanged from 2016 levels, based upon the Compensation Committee's assessment that such targets were reasonable and appropriate.

        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 executive officers, the actual amount of annual cash bonus awarded for 2017 was based on a highly subjective 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 the annual bonuses should be tied to overall Company performance such as significant strategic developments (as assessed by the Compensation Committee) and financial performance, particularly for the most senior members of our management team, such as our Chief Executive Officer and Chief Financial Officer.

        Our corporate performance has historically been reviewed by reference to year over year consolidated Company performance and our Compensation Committee will take 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 2017, the weight assigned to each performance factor generally ranged from approximately 35-50% for Company operational and financial performance, 35-50% for individual achievements, including accomplishment of individual goals set for the 2017 fiscal year, and 15% for general individual performance, including overall quality of the individual's work performance throughout the year. 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 or decrease such amount or weight range for each performance metric based on the Compensation Committee's review of such individual's performance

and relevant job responsibilities. For the Chief Executive Officer, the Committee generally assigns a 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 bonus opportunity percentage as more of a ceiling. For 2017, we paid the annual bonuses to our named executive officers described under the column entitled "Bonus" in the Summary Compensation Table for the reasons described below.

        Our Chief Executive Officer was paid an annual bonus of $375,000, representing 63% of his 2017 annual bonus opportunity. In determining compensation for all executive officers, the Compensation Committee took note of the Company's unfavorable financial and operating results and performance below plan in its International Telecom and Renewable Energy segments due primarily to the impact of two severe hurricanes in the U.S. Virgin Islands, as well as delays in the India solar plant builds. While the hurricane impacts were not avoidable and the Board did approve of a number of steps the Chief Executive Officer has taken to position the Company for the future and improved performance, the Compensation Committee felt these poor results should be reflected in the entire management team's bonuses, including that of the Chief Executive Officer.

        In reviewing with the Chief Executive Officer the recommendations for annual bonuses to be paid to the other executives, the Compensation Committee considered each officer's contribution to achieving the Company's financial performance and strategic goals, using the weight ranges described above as a general guide.

        Our Chief Financial Officer was paid an annual bonus of $210,000, or 78% of his 2017 annual bonus opportunity. The Compensation Committee viewed his individual and team performance favorably, particularly (i) his continued work around the improvement of finance, accounting and tax reporting of the Company's three major new businesses in three separate offshore markets, (ii) the integration and development of the recently expanded and acquired financial and accounting teams, and (iii) his work on improving the Company's capital spending approval process. This individual performance was offset in part by the Company performance noted above.

        The Compensation Committee determined to pay the following annual bonuses to the other named executive officers and took particular note of the additional factors described below:

•

Barry C. Fougere, $120,000 or 51% of his 2017 annual bonus opportunity, reflecting the adverse impacts to Company performance noted above as well as the impact of other major projects performing below plan, offset in part by his achievements in other areas such as support of the senior management team at several operating subsidiaries and improvements to certain shared service platforms;



•

William F. Kreisher, $93,000 or 70% of his 2017 annual bonus opportunity, reflecting the adverse impacts to Company performance noted above, offset in part by the completion of some smaller transactions and creation of some new growth initiatives; and



•

Leonard Q. Slap, $93,000 or 65% of his 2017 annual bonus opportunity, reflecting the adverse impacts to Company performance noted above, offset in part by the completion of several transactions and his work on some ongoing and complex Company matters.

Annual Equity Awards

        Under our 2008 Plan, we may grant stock options, restricted stock and other equity awards to our directors, consultants and employees, including our executive officers. Awards made under the 2008 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 directors, grants awards to our employees under our

Table of Contents

2008 Plan. Our Chief Executive Officer also has authority to make limited grants under the 2008 Plan to employees of the Company.

        In addition to annual equity awards to our officers, we have awarded significant equity compensation in connection with the hiring or promotions of executive officers. For new hires, the awards typically are made at the next regularly scheduled Compensation Committee meeting following the hire or promotion. In general, we have awarded restricted stock and stock options with time-based vesting schedules of four years, and, in the case of stock options, having a term of ten years. Since 2013, the majority of the equity awards granted by the Compensation Committee have been in the form of restricted stock and it has not issued option awards to our named executive officers. This year, the Compensation Committee granted equity awards in the form of restricted stock units. The Compensation Committee believes that, at this time, given the Company's disciplined, long-term approach to its investing and operating strategy, restricted stock units are a good tool for aligning, incentivizing, retaining and rewarding our executive officers and more in line with peers than grants of shares of restricted stock. The Compensation Committee, however, continues to consider other equity-linked incentives from time to time.

        On March 7, 2018, the Compensation Committee granted the following equity compensation to the Company's named executive officers as compensation for each executive's 2017 achievements and general performance of the Company, as described in our Annual Cash Bonus disclosure above:

        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 restricted stock unit grant awards described above would not be likely to encourage excessive risk taking, as the restricted stock units awards typically vest ratably over a period of four 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 and unvested restricted stock units at a reasonable level in relation to our outstanding equity (calculated on a fully diluted basis), we believe that equity compensation will remain a critical recruitment, retention and incentive tool.

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 our executive officers. It 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 quarterly 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, 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 Transactions in 2017 for additional information regarding the compensation plan. Executives hired after 2008 do not participate in this plan. Except for

this plan, our executive officers currently do not receive any benefits, including retirement, medical and dental, life and disability insurance, which are not also available to all of our employees.

Severance Agreements

        In 2016, we entered into severance agreements with each of our named executive officers. 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 base salary (and in the case of our Chief Executive Officer, or CEO, one and a half times his 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 CEO). In the event of a termination by the Company without "cause" or by the executive for "good reason" either three months prior to or twelve months (eighteen months in the case of the CEO) following a change in control (as defined in the Executive Severance Agreements), such executive would be entitled to (i) severance pay in the amount of one times (and in the case of the CEO, one and a half times) his base salary, (ii) such executive's maximum target incentive compensation for such year (and in the case of the CEO, 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 during the twelve months following the termination (eighteen months in the case of the CEO) and (iv) the immediate vesting of all restricted stock, restricted stock units or stock options held by such executive.

"Say on Pay" Advisory Approval of Executive Compensation

        At the 2017 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 every three years. Stockholders will again be asked, on an advisory basis, to approve the compensation of our named executive officers at the 2020 Annual Meeting. At the 2017 Annual Meeting, more than 80% of the shares present, or present by proxy, and entitled to vote at the 2017 Annual Meeting approved our named executive officer compensation. While the approval in 2017 was advisory and non-binding in nature, the Board of Directors 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. As a consequence, the Compensation Committee has not made significant changes in our executive compensation programs as a result of the advisory vote.

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.

Non-Qualified Deferred Compensation Plan Transactions in 2017

        The following table sets forth contributions by us to our deferred compensation plan for fiscal 2017.

        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 quarterly credits equal to 8% of the executive officer's then current quarterly base salary to an account in the plan on behalf of the executive. In addition to these quarterly 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 from among alternatives approved by the Compensation Committee. 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 nonforfeitable 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 29, 2017, the last business day of our fiscal year, and using the closing market price of our common stock on that date $55.26.

        Mr. Fougere departed from his position as Executive Vice President, Business Operations, effective April 13, 2018. Mr. Fougere has executed an agreement with the Company that includes a release, waiver and other customary provisions and will receive the severance pay provided for under his severance agreement, dated March 6, 2016, with the Company.

        Mr. Slap departed from his position Senior Vice President, General Counsel and Secretary, effective March 16, 2018. Mr. Slap has executed an agreement with the Company that includes a release, waiver and other customary provisions and will receive the severance pay provided for under his severance agreement, dated March 6, 2016, with the Company.

Pay Ratio Disclosure

        Pursuant to recently adopted rules under the Dodd-Frank Act, we have included in this Proxy Statement disclosure of a reasonable estimate of the CEO to median employee pay ratio for 2017 annual compensation. We identified the median employee based on 2017 taxable wages for all individuals, excluding our CEO, employed by us on December 31, 2017 (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 2017 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 2017 Summary Compensation Table set forth elsewhere in this Proxy Statement. The annual total compensation of our median employee for 2017 was $32,000. As disclosed in the Summary Compensation Table, our CEO's annual total compensation for 2017 was $2,672,681. Based on the foregoing, our estimate of the ratio of the annual total compensation of our CEO to the median of the annual total compensation of all other employees was 84:1.

        The foregoing calculation reflects employees located in all of the Company's operating jurisdictions. At year end, we had approximately 700 employees in the United States and the United States Virgin Islands, and approximately 1,100 employees internationally, principally in Bermuda, the Cayman Islands, Guyana and India, with employees in Guyana accounting for over half of our employees outside of the United States. Our estimate, using the same compensation measure of taxable wages, of the ratio of the annual total compensation of our CEO to the median of the annual total compensation of our United States employees (excluding the CEO) is 34:1. Given the different methodologies that public companies will use to determine an estimate of their pay ratio, the estimated ratios reported above should not be used as a basis for comparison between companies.

        In order 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 various years ranging from 2013 through 2017 is set forth below. This information regarding GDP per capita is deemed to be furnished and not filed.

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 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.

        The table below summarizes the compensation paid to, or earned by, our non-employee directors for the fiscal year ended December 31, 2017. Mr. Michael Prior, our Chief Executive Officer, does not receive any compensation for his Board service beyond the compensation he receives as an executive officer of the Company.

2017 Director Compensation Table

        The table below summarizes the compensation earned by each named director as of December 31, 2017:

        In connection with Mr. C.B. Prior, Jr.'s retirement from the Board of Directors, effective as of the date of the Annual Meeting, the Compensation Committee has determined that, in recognition of Mr. C.B. Prior, Jr.'s pre-retirement service to the Company, the Company will provide to Mr. C.B. Prior, Jr. following his retirement (i) COBRA benefits for a period of eighteen (18) months, (ii) an office space for use for a period of three (3) years with an approximate value of $33,600 per year and (iii) a gift of the Company car used by Mr. C.B. Prior, with an approximate value of $12,000.

Retainers

        For the fiscal year ended December 31, 2017, our non-employee directors (excluding our Chairman) received an annual retainer of $155,000 (consisting of $50,000 in cash and $105,000 in stock). In addition to the retainers, members of the Audit, Compensation and Nominating and Corporate Governance Committees (other than the Chairs of such committees) received additional annual payments of $10,000, $7,500 and $2,000, respectively, and the Chairs of the Audit, Compensation and Nominating and Corporate Governance Committees received annual payments of $20,000, $15,000 and $6,000, respectively.

RELATED PERSON TRANSACTIONS

Policy on Related Person Transactions

        Our Board has a written Related Person Transaction Policy that sets forth our policies and procedures for the reporting, review, and approval or ratification of each related person transaction. Our Audit Committee is responsible for implementing this policy and determining whether any related person transaction is in our best interests. The policy applies to transactions and other relationships that would need to be disclosed in this Proxy Statement as related person transactions pursuant to SEC rules. In general, these transactions and relationships are defined as those involving a direct or indirect interest of any of our executive officers, directors, nominees for director and 5% stockholders, as well as specified members of the family or household of any of these individuals or stockholders, where we or any of our affiliates have participated in the transaction(s) as a direct party or by arranging the transaction(s) and the transaction(s) involves more than $100,000 in any calendar year. The policy also provides that certain types of transactions are deemed to be pre-approved or ratified, as applicable by our Audit Committee.

        In October 2014, our U.S. Virgin Islands business, Choice Communications, LLC ("Choice"), entered into a tower lease with Tropical Telecom Ltd ("Tropical Telecom"), an entity 74% owned by Mr. C.B. Prior, Jr., our Chairman. When aggregated with amounts that Choice currently pays to Tropical Telecom for an existing tower lease entered into in April 2012, Choice will pay approximately $117,000 per year in rental payments to Tropical Telecom. Each tower lease has an initial term of five years, with two additional five year renewal periods and has provisions for an increase in rent, in the case of the April 2012 lease, by 5% each year and in the case of the October 2016 lease by 3% each year.

        Our Audit Committee approved the specific structure and terms of the Choice lease, as negotiated by Choice management, and unanimously approved each of the arrangements described above in accordance with the terms of our Related Person Transaction Policy.
