PROXY STATEMENT
FOR THE 2022 ANNUAL MEETING OF STOCKHOLDERS
TO BE HELD ON JUNE 7, 2022
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 2022 Annual Meeting of Stockholders to be held on June 7, 2022, at 9:00 a.m. ET (the “Annual Meeting”), or any adjournments or postponements thereof.
Pursuant to certain rules of the U.S. Securities and Exchange Commission (“SEC”) that allow issuers to furnish proxy materials to stockholders over the Internet, we are posting our proxy materials on the Internet and delivering a Notice of Internet Availability of Proxy Materials (the “Notice”) containing instructions on how to access or request a copy of our Proxy Statement, our Annual Letter to Stockholders and our Annual Report on Form 10-K for the year ended December 31, 2021 (excluding exhibits). We first mailed the Notice to stockholders on April 28, 2022, unless they requested printed copies of our proxy materials. If you would like to receive a paper or e-mail copy of our proxy materials, please follow the instructions in the Notice. If you requested printed versions of these materials by mail, they will also include a proxy card for the Annual Meeting on June 7, 2022.
Important Notice Regarding the Availability of Proxy Materials for the Annual Meeting of Stockholders to be held on June 7, 2022: This Proxy Statement and our 2021 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 14, 2022 are entitled to vote at the Annual Meeting. On that date, 15,742,780 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. On April 28, 2022, we mailed the Notice to stockholders, unless they requested printed copies of our proxy materials. The Notice contains instructions on how to access our proxy materials and how to vote. You may vote over the Internet or by telephone prior to the Annual Meeting, or, if you requested printed copies of our proxy materials, by completing, dating and returning a proxy card. Please review the instructions on the Notice or on the proxy card regarding your voting options. Any proxy that is voted according to the instructions included in the Notice or on the proxy card will be voted in the manner instructed by the stockholder, and if no instructions are given, the shares represented thereby will be voted by the proxy holders as follows:
•
FOR the election of the director nominees named herein;
​
•
FOR the ratification of the appointment of PricewaterhouseCoopers LLP as our independent auditor; and
​
1

TABLE OF CONTENTS​​​​​
•
in accordance with the judgment of the proxy holders named on the proxy as to any other matter that is properly brought before the Annual Meeting, or any adjournments or postponements thereof.
​
If you hold your shares through a bank, broker or other nominee, the bank, broker or other nominee will give you separate instructions for voting your shares. Telephone and Internet voting will also be offered to stockholders owning shares through certain banks and brokers. You must make arrangements with your bank, broker or other nominee in advance of the Annual Meeting to vote your shares in person.
Quorum
The holders of a majority of the outstanding shares of common stock entitled to vote at the Annual Meeting, whether present in person or represented by proxy, will constitute a quorum for the transaction of business at the Annual Meeting. If a quorum is not present at the Annual Meeting, the stockholders present may adjourn the Annual Meeting from time to time, without notice, other than by announcement at the meeting, until a quorum is present or represented. At any such subsequent meeting at which a quorum is present or represented, any business may be transacted that might have been transacted at the original meeting. Abstentions and broker non-votes will be counted for purposes of determining whether a quorum is present at the Annual Meeting.
Votes Required
Proposal 1, the election of each director nominee, requires the affirmative vote of a majority of the votes cast and entitled to vote at the Annual Meeting regarding such director nominee’s election. Abstentions and broker non-votes are not considered votes cast for the foregoing purpose and will have no effect on the election of the director nominees. A broker non-vote occurs when a bank, broker or other nominee cannot vote a customer’s shares registered in the bank’s, broker’s or other nominee’s name because the customer did not send instructions on how to vote on the matter and the bank, broker or nominee is prohibited by law or stock exchange regulations from exercising its discretionary voting authority in the particular matter. Banks, brokers and other nominees will not be entitled to vote a customer’s shares in their discretion on Proposal 1.
Proposal 2, the ratification of the appointment of PricewaterhouseCoopers LLP as our independent auditor for 2022 requires the affirmative vote of a majority of the shares present at the Annual Meeting, or represented by proxy, and entitled to vote on the matter. Abstentions will be considered to be votes present and entitled to vote on this proposal and, therefore, they will have the effect of a vote against this proposal. Banks, brokers and other nominees will be entitled to vote a customer’s shares in their discretion on Proposal 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 to ATN International, Inc., Attn: Secretary, 500 Cummings Center, Suite 2450, Beverly, MA 01915. A proxy may also be revoked by re-voting by Internet or by telephone as instructed on your Notice or proxy card, as applicable, or by voting in person at the Annual Meeting. If you hold your shares through a bank, broker or other nominee, you must make arrangements with your bank, broker, or other nominee to revoke your proxy.
Where Can I Find the Voting Results of the Annual Meeting?
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
2

remuneration, may solicit proxies by telephone, e-mail, facsimile and personal interviews.

TABLE OF CONTENTS​​​
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
April V. Henry
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. John C. Kennedy 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, 2022. 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, 2021.
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 2022 requires the affirmative vote of a majority of the shares present, or represented by proxy, at the Annual Meeting and entitled to vote thereon. Abstentions will be considered to be votes present and entitled to vote on this proposal and, therefore, they will have the effect of a vote against this proposal. Banks, brokers and other nominees will be entitled to vote a customer’s shares in their discretion on this proposal, so there will be no broker non-votes on this proposal.
Recommendation of our Board of Directors
OUR BOARD UNANIMOUSLY RECOMMENDS THAT STOCKHOLDERS VOTE FOR THE RATIFICATION OF THE SELECTION OF THE INDEPENDENT AUDITOR FOR 2022.

CORPORATE GOVERNANCE
General
The role of the Board is to ensure that we are managed for the long-term benefit of our stockholders. The Board periodically reviews and advises management with respect to our annual operating plans and strategic initiatives. The Board has adopted corporate governance principles to support compliance with all applicable corporate governance standards.
During the past year, we have reviewed our corporate governance practices in comparison to the practices of other public companies and to ensure they comport with guidance and interpretations provided by the SEC and the Nasdaq Stock Market (“Nasdaq”).
We have a written Code of Ethics that applies to all of our employees and agents, including, but not limited to, our principal executive officer, principal financial officer and principal accounting officer, or persons performing similar functions. Our Code of Ethics, Nominating and Corporate Governance Committee Charter, Compensation Committee Charter, Investment Committee Charter, and Audit Committee Charter are available on our website at 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 determined to appoint a Lead Independent Director in 2018 and Liane J. Pelletier has served in the role since that time. Following this year’s Annual Meeting, the Board intends to appoint Dr. Bernard J. Bulkin as the Company’s Lead Independent Director to serve for a term of up to three years, assuming his re-election to the Board each year. The Lead Independent Director is an independent, non-employee director designated by the Board to serve in a lead capacity to coordinate the activities of the other non-employee directors, interface with and advise management, and perform such other duties as the Board may determine. Although the Board does not have a 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. 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 2022, all of our directors elected to self-disclose certain gender identity and demographic background characteristics to disclose the diversity make up of our Board in line with Nasdaq’s Board Diversity Rule and as set forth in the table below. Although the Board chose to disclose in accordance with these guidelines, the Board values the diverse viewpoints and skillsets of all its Board members.

TABLE OF CONTENTS
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, 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. | ​ | ​ | ​ | 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 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 independent director nominees currently have an average tenure of 4.2 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.
Board Refreshment
Over the past five years, our Board has undergone significant change as part of a conscious effort, led by the Nominating and Corporate Governance Committee, to refresh the Board and augment its composition with fresh, diverse perspectives and complementary skills and experiences that are aligned with the Company’s long-term strategy. In total, our Board has added four new directors—comprising a majority of the independent directors of the Board -since 2017, with two longer-tenured directors stepping down during that time.

TABLE OF CONTENTS​​
The graphics below illustrate the efficacy of our Board refreshment in reducing the average tenure and age of the Board and enhancing the Board’s gender diversity:
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 all of our current directors and director nominees, with the exception of Mr. Prior, are independent for purposes of applicable SEC and Nasdaq rules.
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
14

TABLE OF CONTENTS​​
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, 2021, 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 2021 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.”

All communications received (other than advertisements and similar items) will be directly sent to the Board or to individual members of our Board, as addressed.
Board of Directors’ Meetings and Committees
During 2021, our Board met nine times. In 2021, 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 four standing committees: the Audit Committee, the Compensation Committee, the Nominating and Corporate Governance Committee, and the Investment Committee. The current membership of each committee is as follows:

​ | Audit Committee | ​ | ​ | Compensation Committee | ​ | ​ | Nominating and Corporate Governance Committee | ​ | ​ | Investment Committee | ​
​ | Pamela F. Lenehan, Chair | ​ | ​ | Richard J. Ganong, Chair | ​ | ​ | John C. Kennedy, Chair | ​ | ​ | James S. Eisenstein, Chair | ​

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

​
Our Board has determined that each current member of the Audit Committee meets the financial literacy requirements of Nasdaq. It has also determined that Ms. Lenehan, who is currently the Chair of the Audit Committee, qualifies as an “audit committee financial expert” under the rules of the SEC and meet 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 is independent under applicable Nasdaq and SEC rules for audit committee members.
Compensation Committee
The Compensation Committee met three times during 2021 and once in 2022 to discuss executive compensation for the 2021 year, and the Chair of the Compensation Committee met several times with the Chief Executive Officer as well. 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 the Compensation Committee Charter; and
​
•

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 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.

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, 2021, as well as the other individuals included in the Summary Compensation Table below.
Compensation Philosophy
The primary objective of our executive compensation program is to attract, retain and reward executive officers who contribute to our long-term success and to maintain a reasonably competitive compensation structure as compared with similarly situated companies. We seek to align compensation with the achievement of business objectives and individual and Company performance. The annual cash bonus opportunity together with equity compensation that we provide our executive officers are our main incentive compensation tools to accomplish this alignment, as described below.
A core principle of our compensation philosophy to date is that a successful compensation program requires the application of judgment and subjective determinations of individual performance. With respect to our annual cash bonus opportunity, while we do assign an indicative weight to individual and general Company performance in determining an executive officer’s compensation, 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.
For 2022, the committee took the same approach, and accordingly, equity grants to executive officers made in March 2022 for 2021 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 restricted stock units and performance stock units can be found in the “Annual Cash and Equity Bonuses—Annual Equity Awards” discussion on page 27 and relating to all long-term equity grants can be found in the “Grants of Plan-Based Awards” table located on page 34 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 six years, Compensia has assisted the Compensation Committee with the identification of a relevant peer group and competitive market compensation data regarding the compensation of our named executive officers and directors as compared with the peer group. Compensia does not generally provide any other services to the Compensation Committee, except as may be requested from time to time with respect to specific matters and as described below.
In 2021, 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

TABLE OF CONTENTS
award program, and update the Compensation Committee on recent or pending changes to the rules and industry trends on executive compensation.
Compensia works at the direction of, and reports directly to, the Compensation Committee, which may replace the compensation consultant or hire additional advisors at any time. Compensia does not perform any services for the Company unless directed to do so by the Compensation Committee. Based on an analysis of the various factors set forth in the rules of the SEC, the Compensation Committee does not believe that its relationship with Compensia or the work of Compensia on behalf of the Compensation Committee have raised any conflicts of interest, and the Compensation Committee believes that Compensia is independent.
External Sources
Generally, we seek to offer executive compensation that is reasonably competitive with telecommunications companies of a similar size. Defining a relevant “peer group” for us has been historically 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 2021, our Compensation Committee referred to the executive compensation paid at the following group of companies:

​ | 8 x 8 | ​ | ​ | Gogo | ​ | ​ | RingCentral | ​
​ | Bandwidth Inc. | ​ | ​ | IDT | ​ | ​ | Shenandoah Telecommunications | ​
​ | Brightcove | ​ | ​ | Limelight | ​ | ​ | Switch Inc. | ​
​ | Cincinnati Bell | ​ | ​ | ORBCOMM Inc. | ​ | ​ | Wide Open West | ​
​ | Cogent Communications | ​ | ​ | Pattern Energy Group | ​ | ​ | Vonage Holdings | ​
​ | Consolidated Communications | ​ | ​ | ​ | ​ | ​ | ​ | ​

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. This year, the Compensation Committee determined to make certain changes to the Company’s peer group, such as removing Boingo Wireless, which was acquired, and replacing Iridium Communications and ViaSat with Brightcove, IDT, Limelight and Wide Open West to better align to the relative size of the Company as well as its diversity and reach of operations. 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.

TABLE OF CONTENTS
Elements of Compensation
Overview
Our executive compensation program is focused on three separate elements:
•
base salary;
​
•
annual cash bonuses; and
​
•
equity awards.
​
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 2021. For 2021, the Committee decided to provide basic cost-of-living increases for Messrs. Prior, Benincasa, and Ms. Mabey. In March 2021, Mr. Martin was promoted to Chief Operating Officer and the Board recognized that promotion by increasing his annual base salary to reflect his additional responsibilities.

Named Executive Officer | ​ | ​ | 2021 | ​ | ​ | 2020 | ​ | ​ | Annualized Percent Change from 2020 | ​
Michael T. Prior | ​ | ​ | ​ | $ | 661,000 | ​ | ​ | ​ | ​ | $ | 645,000 | ​ | ​ | ​ | ​ | ​ | 2.5% | ​ | ​
Justin D. Benincasa | ​ | ​ | ​ | $ | 398,000 | ​ | ​ | ​ | ​ | $ | 390,000 | ​ | ​ | ​ | ​ | ​ | 2.1% | ​ | ​
Brad W. Martin | ​ | ​ | ​ | $ | 365,000 | ​ | ​ | ​ | ​ | $ | 335,000 | ​ | ​ | ​ | ​ | ​ | 9.0% | ​ | ​
Mary M. Mabey | ​ | ​ | ​ | $ | 285,000 | ​ | ​ | ​ | ​ | $ | 275,000 | ​ | ​ | ​ | ​ | ​ | 3.6% | ​ | ​

On January 15, 2021, Mr. Kreisher agreed to reduce his responsibilities to the Company and as of that date, no longer served in a role as an executive officer of the Company. Accordingly, his salary was reduced from $282,000 to $210,000 and his 2021 bonus opportunity was decreased from 50% to 35% of his base salary for the 2021 year in connection with his reduced role. Mr. Kreisher was awarded 3,400 restricted stock units in 2022 in recognition of his performance in 2021.
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.
24

TABLE OF CONTENTS
For 2021, the annual bonus opportunity for each of our named executive officers was as follows:

Named Executive Officer | ​ | ​ | 2021 Annual Bonus Opportunity Expressed as % of Base Salary | ​
Michael T. Prior | ​ | ​ | ​ | ​ | 100% | ​ | ​
Justin D. Benincasa | ​ | ​ | ​ | ​ | 75% | ​ | ​
Brad W. Martin | ​ | ​ | ​ | ​ | 75% | ​ | ​
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. In recognition of his promotion to Chief Operating Officer, Mr. Martin’s target bonus opportunity was increased in March 2021 from 60% to 75%. The target amounts of the bonuses for all other executive officers for the 2021 year were unchanged from 2020 levels, based upon the Compensation Committee’s assessment that such targets were reasonable and appropriate for such executive officers
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 2021 was based on a review of a number of factors that are each assigned a recommended weight for each executive, which varies based on the roles and duties of each individual. In general, the Compensation Committee believes that annual bonuses should be tied to overall Company performance such as 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, Chief Financial Officer, and Chief Operating 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 2021, 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 2021 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 2021, we paid the annual bonuses to our named executive officers described under the column entitled “Non-Equity Incentive Plan Compensation” in the Summary Compensation Table for the reasons described below.
Michael Prior, our Chief Executive Officer, was paid an annual bonus of $522,000, representing 79% of his 2021 annual target bonus opportunity. In determining the annual bonus and annual equity 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) actual performance against the Company’s financial plan for the year, (ii) the integration of a new acquisition which closed in July, Alaska Communications Systems, Inc.
25

TABLE OF CONTENTS
(“ACS”), (iii) strategic initiatives pursued for the Company’s operating companies, (iv) progress by the Company on key operational objectives, (v) attracting new investors by conveying the Company’s strengths and strategic positioning; and (vi) the performance of the Company’s stock for the year when compared to others in the industry.
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.
Justin Benincasa, our Chief Financial Officer, was paid an annual bonus of $252,000, or 84% of his 2021 annual target bonus opportunity. The Compensation Committee noted, among other things, in recognizing his performance for the 2021 year: his work integrating and closing the ACS acquisition including the alignment of accounting and the finalization, arrangement, and closing of critical debt financing, and managing expenses towards positive consolidated financial results.
Brad Martin was promoted from Executive Vice President, Operations to Chief Operating Officer in March 2021. Mr. Martin was awarded an annual bonus of $232,000, or approximately 85% of his annual bonus opportunity for 2021. Among other things, the Compensation Committee considered: (i) his operational leadership and success in strengthening and augmenting the Company’s subsidiary leadership, (ii) his role in ensuring a smooth operational close and integration plan with respect to ACS, and (iii) his support and conceptual contributions to the Company’s expansion of critical digital infrastructure across multiple markets.
The Compensation Committee determined to pay Mary Mabey, the Company’s Senior Vice President and General Counsel, $120,000, or 84% of her 2021 annual target bonus opportunity, reflecting her work in ensuring a smooth and timely close of the ACS acquisition.
The Compensation Committee determined to pay William F. Kreisher $64,000, or 87% of his 2021 annual target bonus opportunity, reflecting his work on the ACS acquisition and a number of other 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 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.
In 2021, 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 underperformed the broader market, the Compensation Committee decided to introduce performance stock units as an element of long-term 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.
26

TABLE OF CONTENTS
Accordingly, half of the annual equity compensation award to each executive officer in March 2022 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 25, 2022, 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 25, 2025 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 25, 2025.
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 25, 2025, 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 25, 2026) that the Compensation Committee makes the determination of the Company’s performance relative to the Russell 2000 Index.
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 (“RSUs”) and performance stock units (“PSUs”) to award each recipient by reference to the average closing price for the Company’s common stock for the 20 trading days up to and including the Friday in advance of the Compensation Committee’s meeting during the subsequent week. For grants made on March 25, 2022 for 2021 performance, this amount was $34.96 per share, and for grants made on march 9, 2021 for 2020 performance, this amount was $46.54 per share. The Compensation Committee believes that this practice is a fair manner of dealing with the positive or negative impact of short term movements in the Company’s share price.
The total number of equity compensation awards and value of the awards, utilizing the 20 trading day average per share for grants made in each of the 2021 and 2022 years, is set forth below:

​ | ​ | ​ | Year | ​ | ​ | RSU Awards (#) | ​ | ​ | Value of RSU Awards ($) | ​ | ​ | PSU Awards (at target) (#) | ​ | ​ | Value of PSU Awards (at target) ($) | ​

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 stock unit awards have a cliff vesting period of three years. While the Compensation Committee believes it is an important policy of the Board to seek to keep the aggregate shares underlying outstanding stock options, unvested restricted stock, unvested restricted stock units, and unvested performance stock units at a reasonable level in relation to our outstanding equity (calculated on a fully diluted basis), the Compensation Committee believes that equity compensation will remain a critical recruitment, retention and incentive tool, as well as furthering the alignment of stockholder and employee interests.
Retirement, Benefits and Other Arrangements
In 2008, we adopted a deferred compensation plan for our then-existing executives. This plan is intended to provide retirement income to certain of our executives, including some of our named executive officers (who were executives at the time the plan was adopted). The plan was adopted to offset a reduction in our annual contributions to these executives’ accounts under our 401(k) retirement plan that we instituted as a result of the consolidation of our 401(k) plan with similar plans of companies that we acquired. Under this plan, we make bi-weekly credits equal to 8% of the executive’s then current base salary to an account on behalf of the executive. In addition to these quarterly credits, although we have historically not done so, we may make additional credits in our sole discretion. See the description of the deferred compensation plan under the caption Non-Qualified Deferred Compensation Plan for additional information regarding the deferred compensation plan. Executives hired after 2008 do not participate in this plan. Except for this plan, our named executive officers currently do not receive any benefits, including retirement, medical and dental, life and disability insurance, that are not also available to all of our employees.
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, performance stock units or stock options held by such executive.

TABLE OF CONTENTS
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) aggregate vested shares of restricted stock units and performance 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 stock units, or unexercised stock options. The value is computed as of the last trading day of each fiscal year, based on the closing price of our common stock as reported on Nasdaq, rounded to the nearest 100 shares.
For the calculation of satisfaction of the guideline for non-executive directors, the value of the annual retainer includes amounts payable to such director for annual stock or cash compensation, but does not include any additional retainer paid as a result of service as a Board chair, lead independent director, committee chair or committee member.
Unless and until an executive officer or non-executive director has satisfied his or her applicable guideline level, 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, 2021, however, Messrs. Eisenstein, Ganong, Kennedy, and Martin and Mmes. Henry, 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 four 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.

Effective January 1, 2021, the company no longer makes contributions for Mr. Kreisher.
​
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, 2021, the last business day of our fiscal year, and using the closing market price of our common stock on that date, $39.95.

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 2021 annual compensation. We identified the median employee based on 2021 taxable wages for all individuals, excluding our Chief Executive Officer, employed by us on December 31, 2021 (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 2021 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 2021 Summary Compensation Table set forth elsewhere in this Proxy Statement. The annual total compensation of our median employee for 2021 was approximately $54,116. As disclosed in the Summary Compensation Table, our Chief Executive Officer’s annual total compensation for 2021 was $3,379,851. 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 62:1.
The foregoing calculation reflects employees located in all of the Company’s operating jurisdictions. At year end, we had approximately 1,100 employees in the United States and the United States Virgin Islands, and approximately 1,080 employees internationally, principally in Bermuda, the Cayman Islands, and Guyana, with employees and contractors in Guyana accounting for over half of our employees outside of the United States. For purposes of this calculation, we excluded 4 employees in Canada, as they represent less
36

TABLE OF CONTENTS
than 5% of our employee population. After excluding these employees, we had approximately 1,080 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 37:1.
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.

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.
2021 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, 2021. 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. Ms. April V. Henry joined our Board in March 2022, and therefore did not receive any compensation in 2021.

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 4, 2021. This had the effect of making the dollar value of the stock award higher than the $120,000 retainer as described below.

​
Retainers
For the fiscal year ended December 31, 2021, our non-employee directors received an annual retainer of $170,000 (consisting of $50,000 in cash and $120,000 in stock). After noting the fairly wide swings in share prices that can occur in the weeks leading up to the equity award determination, the Compensation Committee determined the number of shares to award each non-employee director by reference to the average closing price for the Company’s common stock for the 20 trading days up to and including June 4, 2021. The Compensation Committee believes that this practice is a fair approach to deal with the positive or negative impact of short term movements in the Company’s share price. In addition to these retainers, our Lead Independent Director also receives an additional annual cash retainer of $25,000 and members of Committees of our Board received additional annual cash payments as follows:

ADDITIONAL INFORMATION
Environmental, Social and Governance Business Integration
We are committed to imbedding our Environmental, Social and Governance (“ESG”) objectives in our business fundamentals and strategies and believe they are built on a strong foundation of transparency and ethics. Our resolve to manage ESG commitments starts with our Board and flows down to executive leadership through to our subsidiaries. We have always paid attention to principles of good governance, corporate citizenship, and environmental stewardship. We believe that strong management of these aspects are all critical to the long-term success of the Company.
Board of Directors Oversight
Our Board has oversight for our ESG strategy, including related policies, programs, and reporting matters. The full Board engages in the impacts of our human capital management strategy, focusing on areas such as corporate culture and employee engagement. Our Audit Committee oversees the Company’s progress on its objectives regarding environmental management, our Nominating and Corporate Governance Committee oversees the Company’s process 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.
Executive Oversight
We understand that advancing our ESG strategy starts at the top with our senior management and flows to our entire organization. To that effect, we have formed an internal Sustainability Council comprised of a diverse slate of representatives from all our locations and subsidiaries. The Sustainability Council’s mandate is to assist with identifying opportunities and establishing metrics by which to form our ESG program and the communication of ESG messaging within the organization to identify local ESG projects given the uniqueness of our rural and remote markets.
Compliance, Anti-Bribery and Anti-Corruption
Our General Counsel provides oversight of compliance and ethics controls, training, and risk assessments and is responsible for our corporate compliance program, which promotes an ethical culture that is compliant with laws, regulations and policies. Our General Counsel reports quarterly on inquiries to our ethics hotline and regularly to the Audit Committee with respect to compliance and ethics-related trends, risks, and action plans.
Network and Data Security and Privacy
Network and data security is crucial to our mission of delivering connectivity services that both our retail and enterprise customers can trust. Our IT department has developed the Company’s cybersecurity program based on NIST standards, with the oversight of our Audit Committee with respect to the Company’s risk management strategy. Both our IT department and our General Counsel regularly report on data security-related industry trends and developments, and have undertaken compliance with local and state privacy regulations in the markets in which we operate.
Supply Chain Management
Our procurement organization is responsible for negotiating and contracting for products and services and is a strategic component of our business. We expect supplier business operations to be conducted in compliance with our Human Rights and Labor Rights and Equal Opportunity Employment, Harassment and Anti-Discrimination policies.
ESG Reporting
We endeavor to provide comprehensive ESG disclosure, starting with the industry-specific Sustainability Accounting Standards Board (SASB) framework. We intend to use our website as a platform to release these disclosures, and continued updates can be located at on our website.

Environmental Impact
Mitigating Climate Change Impacts to our Businesses
We recognize our responsibility to preserve and protect the environment and are aware of the risks related to global climate change and their impacts on our business continuity.
Our Chief Operating Officer and each subsidiary chief executive officers have responsibility for their disaster preparedness plans for their specific local risks, including climate-related risks. We have invested in hardening our network assets against major storms, including undergrounding where possible, using composite rather than wooden poles to withstand high wind speeds and reducing the weight of our network spans 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 and the Cayman 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 monitor the integrity of the seawall protecting the city of Georgetown from rising sea levels that can in turn impact our communications networks.
While we continue to monitor the impact that environmental related events may have on our businesses, we are conscious of the impact that our business may have, in turn, on the environment. Our services enable remote work, tele-health, and remote learning by delivering high speed data connectivity to consumers, businesses and government entities often in remote and historically underserved markets. As was made even clearer during the pandemic, these connections and services both bring much-needed connectivity to communities while also greatly reducing the need for travel. Increasingly, we are providing solutions that further this impact such as managed network services that help enterprise customers remove power dependent local equipment and reduce the need for travel to other locations.
We are working on ways to minimize the environmental impact from our operations, such as materials waste generated by our operations and improving automation that will reduce truck rolls needed to support customers, maintain networks and develop our business. While we cannot eliminate these impacts, we continue to deploy measures in an effort to reduce impacts and, in many cases, those same measures may provide economic benefits to our business. For example, we have launched recycling initiatives in our offices and field facilities, and are exploring opportunities to expand those programs, particularly the recycling of work materials like metals, rubber and plastics.
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.
Upcycling and Reuse
The consequences of e-waste disposal pose a serious threat to the environment. The negative effects extend from the soil to water resources and the air we breathe, to help combat the accumulation of landfill waste, we invested in 2021 in an e-device repair company to repurpose broken mobile devices in Bermuda. Based on the success of this program, we are seeking to expand our device repair services to encourage the re-use of handheld devices by many of our operations in the Caribbean.
Human Rights
We believe in respect for human rights as a foundational principle. As an international communications service provider, we strive to respect and promote human rights in all the markets in which we do business. Our Human and Labor Rights Policy is guided by the international human rights principles encompassed by The International Bill of Human Rights and the International Labor Organization’s 1998 Declaration on Fundamental Principles and Rights at Work. This policy applies to all entities that we own or in which we hold a majority interest.

TABLE OF CONTENTS​​
Human Capital
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. We seek to promote diversity, equity and inclusion across our workforce, and work to position all employees to succeed. Our annual employee engagement survey provides employees with the opportunity to share confidential feedback and this information drives our long-term plans to improve our work culture. Focus areas for engagement include skills development, and manager performance.
We are working hard to improve the way technology is used in the diverse communities we serve. We believe it is a critical element of our success that our management and staff are local, and are a reflection of the diverse talent available in the communities that we serve. As a result, across our core businesses in all our markets, approximately 30% of our senior management and an additional 40% of middle management identify as persons of color, including Afro-Caribbean, Latinx, Indo-Caribbean and other races or ethnicities and approximately 15% of senior management and an additional 40% of middle management are women.
Digital Divide
We aspire to make a positive difference by enriching lives in remote and underserved areas through reliable and affordable connectivity to promote remote work, learning and commerce opportunities. We acknowledge the hardships facing these communities which has been exacerbated by the pandemic and we have increased our efforts to provide connectivity in these challenging areas and support their forward growth. During the height of the pandemic, our Choice Wireless, NTUA Wireless, and Viya subsidiaries signed the “Keeping Americans Connected” pledge, providing internet access for residents, students, and small business. Our Alaska Communications subsidiary has expanded broadband service connecting tens of thousands of underserved locations in some of the most remote areas, providing access to telemedicine, and economic and education opportunities. Our Commnet and NTUA Wireless subsidiaries are working on numerous projects, many of which are partially funded by government grants, to bring fiber into underserved communities including tribal lands and other rural and remote areas. We are doing the same internationally by rapidly deploying fiber and other high-speed solutions to connect homes, businesses, schools, and towers in places like Guyana and the Cayman Islands.
Additional information on our philanthropic and community support initiatives can be found on our website under our corporate responsibility page.
