PROXY STATEMENT
FOR THE 2021 ANNUAL MEETING OF STOCKHOLDERS
TO BE HELD ON JUNE 10, 2021

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 (the “Company,” “we,” “us,” and “our”), for use at the 2021 Annual Meeting of Stockholders to be held on June 10, 2021, at 9:00 a.m. ET (the “Annual Meeting”), 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, 2020 (excluding exhibits) and a proxy card for the Annual Meeting on April 29, 2021.

Important Notice Regarding the Availability of Proxy Materials for the Annual Meeting of Stockholders to be held on June 10, 2021: This Proxy Statement and our 2020 Annual Report on Form 10-K are available at http://ir.atni.com/financials.cfm.

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 16, 2021 are entitled to vote at the Annual Meeting. On that date, 15,920,141 shares of common stock, par value $0.01 per share, 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 voting 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. ET on June 9, 2021. If your proxy card 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 on your proxy card, 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.

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

1

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 ratification of the appointment of PricewaterhouseCoopers LLP as our independent auditor for 2021 requires the affirmative vote of a majority of the votes cast at the Annual Meeting regarding this matter. Abstentions are not considered votes cast for the foregoing purpose and will have no effect on the ratification of our independent auditor for 2021. Banks, brokers and other nominees will be entitled to vote a customer’s shares in their discretion on Proposal 2, so there will be no broker non-votes on Proposal 2.

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 bank, broker, 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 results, 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.

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. We will reimburse them for their reasonable out-of-pocket expenses incurred in connection with the distribution of the proxy materials. In addition, we will engage Broadridge Investor Communications Solutions, Inc. to assist

2

in the distribution of proxy materials to banks, brokers, nominees and intermediaries at an estimated cost of approximately $20,000 for any such services, plus reasonable out-of-pocket expenses.

PROPOSAL 1: ELECTION OF DIRECTORS

Stockholders are being asked to elect the following seven 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
James S. Eisenstein
Richard J. Ganong
John C. Kennedy
Pamela F. Lenehan
Liane J. Pelletier
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.” Mr. Charles J. Roesslein will not stand for re-election at the Annual Meeting, and, accordingly, will cease to serve as a director following the Annual Meeting. The Board thanks him for his years of service.

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 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: 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, 2021. 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, 2020.

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 2021 requires the affirmative vote of a majority of the votes cast at the Annual Meeting. Abstentions will not be considered to be votes cast and, therefore, they will have no effect on 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 2021.

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 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 (“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 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 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, our Chief Executive Officer, has served as our Chairman since June 2018, and the Nominating and Corporate Governance Committee intends to nominate him to continue to serve in such role for the next year, assuming he is re-elected to the Board. In 2018, the Board determined that its leadership structure, including Mr. Prior’s serving as Chairman of the Board and Chief Executive Officer, together with each of the Audit, Compensation, and Nominating and Corporate Governance Committees of the Board, being chaired by, and entirely composed of, independent directors 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 having the Chairman and Chief Executive Officer positions combined aligns corporate strategy development with management oversight of the Board process and, taken together with our Board’s Lead Independent Director role, is the appropriate leadership structure for us at this time.

Since the Chief Executive Officer and Chairman are combined, the Board appointed Liane J. Pelletier as Lead Independent Director, and the Nominating and Corporate Governance Committee intends to re-nominate Ms. Pelletier to serve as Lead Independent Director following this year’s Annual Meeting, assuming she is re-elected to the Board. 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 policy regarding the requirement to appoint a Lead Independent Director, it currently believes that in light of the combined roles of Chairman and Chief Executive Officer, it is appropriate for the Board to continue to have a Lead Independent Director. The Board’s practice has been that such role serves:

•

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 Chief Executive Officer/Chairman and the independent directors, to provide feedback from executive sessions and keep the Board informed of other matters as necessary; and

11

•

as a sounding board, if necessary, to the Chief Executive Officer/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 Corporate Governance Guidelines, as currently in effect. 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 all 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.

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. Our Board believes that diversity among Board members in background, expertise and life experience is beneficial as it expands the range of perspectives brought to Board deliberations. 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. In June 2020, the Board elected a second female director and values the diverse viewpoints and skillsets of all its Board members.

The re-nomination of existing directors is not viewed by our Nominating and Corporate Governance Committee as automatic, but instead is based on continuing qualification under the criteria set forth above. In addition, the Nominating and Corporate Governance Committee evaluates the performance of existing directors on the Board and any applicable committees, which includes consideration of the results of the Board’s biannual self-assessment process as well as the extent to which the directors undertook continuing director education. 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, the Nominating and Corporate Governance Committee maintains a matrix of all skills and attributes represented by current directors and director nominees, as summarized below:

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. More than half of our directors have CEO experience, with most of the Board also including experience in general management, finance, Finance experience.   We believe that as a public company, our Board must have an understanding of our financial reporting processes, risk management policies, and the way we measure our operating and strategic performance by reference to financial goals. Our current slate of director nominees includes a director who qualifies as an “audit committee financial expert” as defined in applicable SEC rules, and we expect all of our

12

operations, technology, or business development. 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.

directors to be financially knowledgeable.

Industry experience.   We seek to have 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 communications industry.

Board Tenure.   We seek 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. In order 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 5.1 years.

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. Prior to making any nomination, our Nominating and Corporate Governance undergoes a rigorous review of a candidate’s background, 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.

In selecting director nominees pursuant to the 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 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. Our Nominating and Corporate Governance Committee may also seek additional information regarding the director nominee candidate and the stockholder making the submission. 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.

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. 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 Messrs. Eisenstein, Ganong, Kennedy, Roesslein, Dr. Bulkin and Mmes. Lenehan and Pelletier are independent for purposes of applicable SEC and Nasdaq rules.

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

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, cyber security risks and the steps management has undertaken to control such risks. 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, 2020, 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 2020 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. 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.”

Board of Directors’ Meetings and Committees

During 2020, our Board met ten times. In 2020, 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 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:

Audit Committee	Compensation Committee	Nominating and Corporate Governance Committee
Charles J. Roesslein, Chair	Richard J. Ganong, Chair	Dr. Bernard J. Bulkin, Chair
Dr. Bernard J. Bulkin	James S. Eisenstein	James S. Eisenstein
Pamela F. Lenehan	Liane J. Pelletier	John C. Kennedy

All members of these committees are independent as defined in applicable Nasdaq rules.

Audit Committee

During 2020, the Audit Committee met seven times, including several sessions at such meetings without members of management or the Company’s independent auditors. Our Audit Committee operates under a written charter that satisfies the applicable standards of Nasdaq and is available on our website at ir.atni.com. The functions of the Audit Committee include:

•

Appointing, approving the compensation of, 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;

•

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 and any other relevant Company policies and overseeing other compliance matters;

•

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 Ms. Lenehan each qualify as an “audit committee financial expert” under the rules of the SEC and meet the financial sophistication requirements of Nasdaq. In addition, our Nominating

15

and Corporate Governance Committee has determined that each of the current members of our Audit Committee is independent under applicable Nasdaq and SEC rules for audit committee members.

Compensation Committee

The Compensation Committee met three times during 2020 and once in 2021 to discuss executive compensation for the 2020 year. Our Compensation Committee operates under a written charter that satisfies the applicable standards of Nasdaq and is available on our website at ir.atni.com. 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 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 and reporting such findings to the Board;

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. 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, 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 finalize, with the Chair, 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 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

16

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.

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, 2020, 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 three times in 2020.

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, 2020, as well as the other individuals included in the Summary Compensation Table below. Mr. William F. Kreisher is listed as a named executive officer for the December 31, 2020, however, as of January 15, 2021, Mr. Kreisher is no longer an executive officer of the Company.

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, we do not apply a strictly formulaic or mathematical approach to our compensation program. With respect to the equity component of executive compensation, in 2021 the Compensation Committee decided to introduce performance stock units as part of the long-term incentive compensation for senior management. The committee took this action to increase alignment between stockholders and senior management with respect to stockholder returns. The committee also recognized that the majority of the company’s peer group have a component of performance equity included in their compensation plans for executives.

Accordingly, equity grants to executive officers made in March 2021 for 2020 performance were split equally between time vested restricted stock units and time and performance vested performance stock units. A description of the terms of the performance stock units can be found in the “Annual Cash and Equity Bonuses—Annual Equity Awards” discussion on page 25 and relating to all long-term equity grants can be found in the “Grants of Plan-Based Awards” table located on page 31 of this proxy statement.

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.

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, a national executive compensation consulting firm. For the past five 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.

21

In 2020, the Compensation Committee asked Compensia to gather peer group data, give advice on any possible changes to the peer group based on that data, advise on the structure of a performance stock unit award program, and update the Compensation Committee on recent or pending changes to the rules and industry trends on executive compensation. In 2020, the Company asked Compensia to gather compensation information with respect to certain subsidiary management roles in the Company’s US Telecom segment.

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 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 useful information regarding appropriate compensation of our named executive officers and directors.

For 2020, our Compensation Committee referred to the executive compensation paid at the following group of companies:

8 x 8	Consolidated Communications	Shenandoah Telecommunications
Bandwidth Inc.	Gogo	Switch Inc.
Boingo Wireless	GTT Communication	ORBCOMM Inc.
Calix	Iridium Communications	ViaSat
Cincinnati Bell	Liberty Latin America	Vonage Holdings
Cogent Communications	Ooma	​

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; 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. As a result, some of our 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 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 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.

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 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 2020 for our named executive officers, in comparison to those in effect in 2019. For 2020, the Committee decided to provide basic cost-of-living increases for Messrs. Prior, Benincasa, Kreisher, and Martin. Ms. Mabey’s base salary was adjusted in 2020 to better align her base salary to that of others in the chief legal officer role in the Company’s peer group.

Named Executive Officer	2019			2020			Annualized Percent Increase from 2018
Michael T. Prior	​	$	630,000	​	$	645,000	​	2.4%
Justin D. Benincasa	​	$	380,000	​	$	390,000	​	2.6%
Brad W. Martin	​	$	325,000	​	$	335,000	​	3.1%
William F. Kreisher	​	$	277,000	​	$	282,000	​	1.8%
Mary M. Mabey	​	$	260,000	​	$	275,000	​	5.8%

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.

23

For 2020, the annual bonus opportunity for each of our named executive officers was as follows:

Named Executive Officer	2020 Annual Bonus Opportunity Expressed as % of Base Salary
Michael T. Prior	​	100%
Justin D. Benincasa	​	75%
Brad W. Martin	​	60%
William F. Kreisher	​	50%
Mary M. Mabey	​	50%

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. For 2020, the target amounts of the bonuses were unchanged from 2019 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 named executive officers, the actual amount of annual cash bonus awarded for 2020 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 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 2020, 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 2020 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 each 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 target bonus opportunity percentage as more of a ceiling in most years. For 2020, 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.

Our Chief Executive Officer was paid an annual bonus of $535,000, representing 83% of his 2020 annual target bonus opportunity. In determining the annual bonus award for the Chief Executive Officer, and, to a lesser extent, all named executive officers, the Compensation Committee considered a number of factors, including (i) achievement of the Company’s financial plan for the year despite the impacts of the COVID-19 pandemic, (ii) limited pandemic-related health and related issues involving employees and customers engaged by employees, (iii) the opportunistic successful launch of a fully financed bid for Alaska

24

Communications Systems, Inc. (“ACS”), (iv) the lack of success on several strategic initiatives pursued for the Company’s operating companies, (v) progress by the Company on key operational objectives, (vi) the success in bringing in a majority partner to the Vibrant Energy business weighed against the low returns and stagnant progress on that investment to date, and (vii) the acquisition on attractive terms of significant minority interests in one of the Company’s operating subsidiaries.

In reviewing with the Chief Executive Officer the recommendations for annual bonuses to be paid to the other executives, the Compensation Committee considered each named executive 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 $243,000, or 83% of his 2020 annual target bonus opportunity. The Compensation Committee noted, among other things, in recognizing his performance for the 2020 year: his work supporting the ACS bid, managing expenses towards positive consolidated financial results, and maintaining a well-functioning accounting and finance function throughout the pandemic.

Brad Martin was promoted from Executive Vice President, Operations to Chief Operating Officer in March 2021, and was awarded an annual bonus of $181,000, or 90% of his annual bonus opportunity for 2020. Among other things, the Compensation Committee considered (i) his strong and successful leadership and support for frontline operating leaders on business adjustments with the onset of the pandemic leading to continuity of services and a limited financial impact, (ii) operational improvements in shared services and go to market positioning in several subsidiaries, and (iii) the completion of several operating initiatives that we believe hold promise for improved efficiencies and a more nimble and informed pursuit of revenue growth.

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:

•

William F. Kreisher, $100,000 or 71% of his 2020 annual target bonus opportunity, reflecting his work on the ACS and Vibrant transactions; and

•

Mary M. Mabey, $114,000 or 83% of her 2020 annual target bonus opportunity, reflecting her work in support of the successful ACS bid and to complete the Vibrant Energy transaction as well as the general management of her team through an extremely complex and busy legal and regulatory year in the midst of the pandemic.

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 named 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 non-employee directors, grants awards to our employees under our 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 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 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 10 years. Since 2013, the majority of the equity awards granted by the Compensation Committee have been in the form of restricted stock and restricted stock units and the Compensation Committee has not granted option awards to our named executive officers during that period.

This year, after reviewing the practices of the Company’s peers and the broader market and taking into account a year in which the Company’s common stock significantly underperformed the broader market, the Compensation Committee decided to introduce performance stock units as an element of long-term

25

incentive compensation for executive officers. At the same time, the 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. 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 stock units, does not encourage undue risk taking or a short-term planning horizon.

Accordingly, half of the annual equity compensation award to each executive officer in March 2021 was composed of performance stock units (based on target level of performance) and half was composed of 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 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 stock unit award agreement, the Company issued a target number of performance stock units on March 9, 2021, with the actual number of performance stock units earned to be determined by comparing the Company’s total stockholder return (“TSR”) over a three-year period ending March 8, 2024 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 8, 2024.

The actual number of shares to be issued upon vesting of the performance 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 8, 2024, 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 15, 2025) that the Compensation Committee makes the determination of the Company’s performance relative to the Russell 2000 Index.

On March 9, 2021, the Compensation Committee granted the following equity compensation to the Company’s named executive officers as part of the long term incentive compensation plan for each executive, as well as a recognition of his or her performance in 2020:

​	Restricted Stock Unit Awards		Performance Stock Unit Awards (at target)
Michael T. Prior	​	19,350	​	19,350
Justin D. Benincasa	​	8,100	​	8,100
Brad W. Martin	​	7,500	​	7,500
William F. Kreisher	​	2,850	​	—
Mary M. Mabey	​	4,800	​	4,800
Total	​	42,600	​	39,750

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 determination and similar movements in previous years, the Compensation Committee determined the number of restricted stock units 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 prior to its meeting date, or March 9, 2021. While it retains discretion to change this approach, the Compensation Committee anticipates continuing to use this method in future years which may result in higher or lower average grants in any given year than under the date of grant approach, as it

26

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.

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 share 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 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. 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.

Severance Agreements

In March 2019, we entered into amended executive agreements with each of our named executive officers that provide severance benefits. 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” either three months prior to, 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 during 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 or stock options held by such executive.

27

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

“Target dollar value” generally is based on the number of (i) shares of common stock and (ii) vested shares of restricted 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 share 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, 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 named executive officers and directors were in compliance with the policy as of December 31, 2020, however, Messrs. Eisenstein, Ganong, Kennedy, and Martin and Mmes. Lenehan and Mabey, have not yet reached the ownership guideline as each of them first became non-executive directors or executive officers in the last three years.

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.

“Say on Pay” Advisory Approval of Executive Compensation

At our 2020 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 our 2023 Annual Meeting. At our 2020 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 2020 Annual Meeting approved our named executive officer compensation. While the approval in 2020 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.

Mr. Martin and Ms. Mabey 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, 2020, the last business day of our fiscal year, and using the closing market price of our common stock on that date, $41.76.

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 2020 annual compensation. We identified the median employee based on 2019 taxable wages for all individuals, excluding our Chief Executive Officer, employed by us on December 31, 2019 (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 2019 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 2020 Summary Compensation Table set forth elsewhere in this Proxy Statement. The annual total compensation of our median employee for 2020 was approximately $43,460. As disclosed in the Summary Compensation Table, our Chief Executive Officer’s annual total compensation for 2020 was $2,653,940. 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 55:1.

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 1,000 employees internationally, principally in Bermuda, the Cayman Islands, Guyana and India, 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 3 employees in Canada, approximately 35

35

employees in India and 4 employees in Singapore, as they represent less than 5% of our employee population. After excluding these employees, we had approximately 1,050 international employees. 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 28:1.

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 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
Bermuda	​	$	99,400
Cayman Islands	​	​	58,808
Guyana	​	​	8,100
U.S. Virgin Islands	​	​	37,000
United States	​	​	59,800

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.

2020 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, 2020. Mr. Michael Prior, our Chairman and Chief Executive Officer, does not receive any compensation for his Board service beyond the compensation he receives as an executive officer of the Company:

Name	Fees Earned or Paid in Cash ($)		Stock Awards ($)(1)		All Other Compensation		Total ($)
Bernard J. Bulkin(2)	​	100,000	​	111,199	​	—	​	211,199
James Eisenstein	​	61,500	​	111,199	​	—	​	172,699
Richard J. Ganong	​	65,000	​	111,199	​	—	​	176,199
John C. Kennedy	​	54,000	​	111,199	​	—	​	165,199
Pamela F. Lenehan	​	60,000	​	111,199	​	—	​	171,199
Liane J. Pelletier	​	82,500	​	111,199	​	—	​	193,699
Charles J. Roesslein	​	73,000	​	111,199	​	—	​	184,199

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 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 12, 2020 and September 11, 2020. This had the effect of making the dollar value of the stock award lower than the $120,000 retainer as described below.

(2)

Includes amount paid for Dr. Bulkin’s service as shareholder director of the Company’s renewable energy business operating under the “Vibrant” name in India.

Retainers

For the fiscal year ended December 31, 2020, our non-employee directors (excluding our Chairman) received an annual retainer of $170,000 (consisting of $50,000 in cash and $120,000 in stock). Due to the fact that the annual meeting for the 2020 year was rescheduled from June to September 2020 as a result of the COVID-19 pandemic, all non-employee directors received their annual retainer in two payments in 2020: one on June 17, 2020 for the period of June 17, 2020 to the date of their re-election to the Board by stockholders on September 15, 2020 and one for the period of September 15, 2020 to the date of their re-election to the Board by stockholders at the 2021 Annual Meeting. After noting the fairly wide swings in share prices that occurred in the weeks leading up to the equity award determination and similar movements in previous years, 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 the Friday prior to its meeting dates, or June 12, 2020 and September 11, 2020. While it retains discretion to change this approach, the Compensation Committee anticipates continuing to use this method in future years which may result in higher or lower average grants in any given year than under the date of grant approach, as it believes that this practice is a fair approach to dealing with the positive or negative impact of short term movements in the Company’s share price.

37

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 cash payments of $10,000, $7,500 and $4,000, respectively, and the Chairs of the Audit, Compensation and Nominating and Corporate Governance Committees received annual cash payments of $23,000, $15,000 and $10,000, respectively. Our Lead Independent Director also receives an additional annual cash retainer of $25,000.

38

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 connection with our Founder and former Chairman Mr. C.B. Prior, Jr.’s retirement from the Board, effective as of June 12, 2018, our Compensation Committee determined that following his retirement, in recognition of Mr. C.B. Prior, Jr.’s pre-retirement service to the Company, the Company would provide him with (i) COBRA benefits for a period of 18 months, (ii) office space for use for a period of three years with an approximate value of $33,600 per year and (iii) a gift of the Company car used by him, with an approximate value of $12,000.

ADDITIONAL INFORMATION

Environmental, Social and Governance Programs

Our Environmental, Social and Governance (ESG) commitments are embedded in our business fundamentals and strategies and built on a strong foundation of transparency and ethics. The Company and its leaders have always paid attention to principles of good governance and corporate citizenship. Similarly, we have paid close attention to environmental risks as they relate to our businesses and have sought to be a good citizen with respect to environmental impacts as well. However, we have found increasing interest from current and prospective stockholders, as well as current and prospective employees and partners, in these areas, particularly environmental and social impacts. Accordingly, we have made an increasing effort to gather and make ESG information about the Company available to interested parties, and to make sure the information we provide is accurate and consistently applied. The main focus of the Company’s leadership is to manage opportunity and risk and deliver for investors, but we believe good governance, strong business ethics and being a good corporate citizen in the communities we operate in all are important to the long term success of the Company.

Our Audit Committee oversees the Company’s progress on its objectives regarding environmental management, our Nominating and Governance Committee oversees the Company’s progress on its objectives with respect to corporate social responsibility and governance and our Compensation Committee oversees the Company’s progress on its objectives with respect to human capital management. The full Board engages in the impacts of our human capital management strategy, focusing on areas such as culture, diversity, equity and inclusion.

Environmental

We thoughtfully consider the demand that our business places on the world’s natural resources. We recognize our responsibility to preserve and protect the environment, and also are aware of the risks related to global climate change, especially our carbon footprint, and examine how they might affect our business. We have invested our capital in a business that provides clean and reliable solar energy solutions to businesses in India, including medical facilities and educational institutions.

Many scientists have suggested that global climate change may cause an increase in the severity and frequency of storms in the Caribbean region. We know that one major storm can cause devastation to the island communities we serve and to our facilities and people that provide critical communications services to those communities. Our businesses focus on refining their disaster preparedness plans for their specific local risks. We have also invested in hardening our network assets so they are less susceptible to storm damage and have detailed plans to return communication services post storm to the communities we serve. In Bermuda, the Cayman Islands, and the U.S. Virgin Islands, we are investing in network monitoring and hardening the physical plant to lessen the potential impact of future storms. In Guyana, which is outside the historic hurricane zone, we also monitor the integrity of the seawall protecting the city of Georgetown from rising sea levels.

We also care about the environmental impact of our operations. We believe that generally our services and investments have very positive impacts on the environment. Most of our revenue is generated by delivering high speed data connectivity to consumers, businesses and government entities. As was made even clearer during the pandemic, these connections and services greatly reduce the need for travel. Increasingly, we are providing solutions that endeavor to further this impact such as managed network services that help enterprise customers remove power-hungry local equipment and reduce the need for travel to other locations. We are also providing solutions that support smart cities and smart buildings with energy efficiencies part of the ultimate objective. Support for tele-health and distance learning also has positive impacts. Still, there may be some negative impacts from our operations, such as materials waste generated by our operations and the driving and travelling we do to support customers, maintain networks and develop our business. While we cannot eliminate these impacts, we continue to deploy measures to reduce them and, in many cases, those same measures provide economic benefits to our business. For example, we have reduced the use of bottled water and launched recycling initiatives in our offices and field facilities, but we are looking into expanding those programs, particularly the recycling of work materials like metals, rubber

40

and plastics. Similarly, we have introduced technology and processes to reduce “truck rolls” to network facilities or customer premises, but we are also looking into further reducing the fuel usage—and maintenance costs—of our fleet of vehicles.

Energy usage in our network and computing equipment is another important area we have targeted for further improvement. In recent years, we have accelerated the replacement of older network equipment which has greatly reduced our power demands and the lower costs and improved quality of service has made those good financial investments as well. We now routinely include power usage in our analysis of new systems and equipment and factor savings into the timing of upgrades and replacements.

Social

We recognize that the first step of our community support efforts rests in the investment we make in one of our most valuable assets, our human capital. The Company’s management seeks to promote diversity, equity and inclusion across our workforce, and works to try to position all employees to succeed. Across our core businesses in all our markets, approximately 30% of senior management and an additional 40% of middle management are racially or ethnically diverse and approximately 15% of senior management and an additional 40% of middle management are women. In 2020, we launched our first ever women’s summit providing an educational framework for participants to approach challenging work and life situations. We also seek to promote the principle of equal pay for equal work.

We provide competitive benefits in an effort to attract and retain talent, including benefits and programs that we hope will support healthy lifestyles, mental health, and retirement preparedness. We also offer general education opportunities for all of our employees and specific training and certification for those employees performing fieldwork. We are focused on expanding educational resources for our employees to keep them informed and aware of opportunities to improve their health and safety.

In 2020, the Company demonstrated its commitment to health and safety through our response to the coronavirus (COVID-19) pandemic. We were able to sustain business operations by implementing pandemic safety and wellness policies. These actions enabled our field operations to continue to deliver mission critical connectivity to the communities we serve. We also recognize the extreme hardships facing the communities we serve created by the pandemic. Our Choice NTUA Wireless and Viya subsidiaries signed the “Keeping Americans Connected” pledge, providing internet access for residents, students and small businesses, and did not terminate connectivity services for nonpayment due to disruptions caused by the pandemic. A few examples of our support of our local communities: NTUA Wireless and the Navajo Tribal Utility Authority partnered with the Public Service Company of New Mexico to install Wi-Fi sites across the Navajo Nation to provide community access to connectivity; in Bermuda, our One Communications subsidiary stepped up to support its local community by contributing to the COVID-19 Emergency Fund of the Third Sector Coordinated Crisis Response Effort, which provides financial support to Bermuda’s non-profit sector; and in the U.S. Virgin Islands our Viya subsidiary provided equipment to the Department of Education to facilitate remote learning.

We always aspire to make a positive difference by enriching lives in remote and underserved areas through reliable and affordable connectivity and curated value added technology solutions. Our communications companies focus not only on vital connectivity to our customers, but also on superior customer service, privacy and data protection. We recognize that investment of corporate resources is a vital element to implement security policies and procedures that inform our employees and protect our networks and data.

We actively seek to encourage the involvement of our employees in their communities through office-wide community involvement days at certain subsidiaries and employee assistance to those impacted by past hurricanes or other disaster events. Our locally run communications services also participate in the sponsorship of community events, local schools, and philanthropic organizations. In Guyana, recognizing the lack of cancer prevention awareness, our GT&T business created its annual “Pinktober” campaign with a mission to provide education on cancer screening and treatment, and to raise funds to contribute to the facilitation of and access to screenings, treatment and psychosocial support. Now in its third year, the month-long campaign, culminating in a charity run/walk/bike ride, has garnered support to unify the country in battling cancer. In the United States, our partnership with the Navajo Nation has helped us to support local

41

youth, from providing free Wi-Fi in school buses, to sponsoring local basketball games, to providing scholarships to the Student Conservation Association, a program designed to instill conservation awareness in our youth.
