Our Environmental, Social and Governance (ESG) Efforts

For the second year in a row, we have published an ESG report, posted on our website, that contains information about our approach to ESG and details of our efforts around environmental impact, human capital, social impact and governance. We have provided selected highlights of our ESG efforts in the section below titled “Information Regarding the Board of Directors and Committees and Corporate Governance – Environmental, Social and Governance (ESG).”

Our Executive Compensation Program

Our executive compensation program is designed to attract, reward and retain a talented, innovative and entrepreneurial team of executives. To do so, we believe that a majority of their target compensation should be based on performance, both of the individual and of the business. We structure our variable compensation programs to recognize both short-term and long-term contributions.

2

Key Elements of Executive Compensation

Compensation Component	Reason
Base Salary	We provide base salary as a fixed source of compensation for our executives for the services they provide to us during the year and to balance the impact of having a significant portion of their compensation “at risk” in the form of annual incentive bonuses and long-term, equity-based incentive compensation. Our Compensation Committee recognizes the importance of a competitive base salary as an element of compensation that helps to attract and retain our executive officers.
Annual Bonus	Our 2021 bonus plan provided compensation opportunities to our executive officers based on our achievement of pre-established performance goals derived from our Board-approved operating plan for 2021. Under our 2021 bonus plan, 60% of each executive’s target performance bonus for the 2021 calendar year was payable in the form of restricted stock units, or RSUs, that only vested upon the Compensation Committee’s determination of achievement of these pre-established performance goals and the executive’s continued service through the vesting date in March 2022. Our 2021 bonus plan provided that the remaining 40% and any bonus amounts earned in excess of 100% of target would be paid in cash. In February 2021, the Compensation Committee approved a target incentive bonus award for each executive and capped the maximum bonus award at 195% of the target level in the event that stretch performance goals were achieved. These levels were consistent with our philosophy that a significant portion of each executive’s total target compensation should be performance-based and reflected the Compensation Committee’s review of internal pay equity. Similarly, under our 2022 bonus plan adopted in February 2022, 60% of each executive’s target performance bonus for the 2022 calendar year will be payable in the form of RSUs that will only vest upon achievement of pre-established performance goals and the executive’s continued service through the vesting date in March 2023. Any bonus amounts earned in excess of 60% of target, up to the maximum award of 185% of the target level, will be paid in cash.
Long-Term Equity- Based Incentive Compensation	The Compensation Committee believes that properly structured equity compensation works to align the long-term interests of stockholders and employees by creating a strong, direct link between employee compensation and stock price appreciation. In 2021, we awarded performance-based RSUs that will provide a return to the executive only if we achieve specific performance targets for 2021 and 2022 and the executive remains employed by us through the applicable vesting date, which could be as late as 2024 in order to achieve full vesting. In 2021, we also awarded RSUs that vest based on continued service over a four-year period, which provide a return only if the executive remains employed with us. In 2022, we made similar awards of performance-based and service-based RSUs.

Important Features of our Executive Compensation Program

The important features of our executive compensation program include:

•Annual Incentive Tied to Performance.Our executive compensation is heavily weighted toward at-risk, performance-based compensation in the form of an annual incentive bonus opportunity that is based on achievement of a combination of financial and operational goals selected annually by our Compensation Committee.

•Long-Term Equity Incentive Compensation. As part of our long-term incentive compensation program, we provide an equity compensation opportunity in the form of performance-based RSUs that provide incentives for our executives to meet certain performance goals, the achievement of which could increase the market value of our common stock, and service-based RSUs, which provide a return only if the executive remains employed with us.

•Significant Percentages of Compensation At-Risk. In 2021, at-risk compensation represented approximately 82% of our chief executive officer’s total direct compensation, and an average of 79% of our other named executive officers’ total direct compensation.

•Performance-Based Equity Awards. Fifty percent of the annual long-term equity-based incentive awards vest only based on the achievement of performance criteria, and if such performance criteria are met, a portion of the vested amount is subject to additional time-based vesting thereafter.

•Reasonable Cash Severance Amounts. The cash severance benefits that we offer to our executives do not exceed two times base salary and annual bonus.

3

•No Tax Gross-Up Benefits. We do not provide our executive officers with any excise tax or other tax gross-ups.

•No Pension or SERP Benefits. We do not provide any defined benefit pension plans or supplemental employee retirement plans to our executive officers.

•Meaningful Executive Stock Ownership Guidelines. As further described in this Proxy Statement, our executives are required to comply with our stock ownership guidelines, which we adopted in 2012. Under these guidelines, our chief executive officer is required to accumulate shares of our common stock with a value equal to four times his annual base salary, and our executive vice presidents, including our chief financial officer, chief operations officer and chief legal officer, are required to accumulate shares of our common stock with a value equal to two times their annual base salaries.

•Prohibition of Hedging and Pledging Transactions. Our insider trading policy prohibits our employees, including our executives, directors and consultants, from hedging or pledging the economic interest in the shares of our company they hold.

•Use of Independent Compensation Consultant. Our Compensation Committee has retained an independent third-party compensation consultant for guidance in making compensation decisions.

•Use of Peer Group and Market Data. Our Compensation Committee reviews market practices and makes internal comparisons among our executives when making compensation decisions.

•Adoption of Compensation Recovery Policy. Our Board adopted a compensation recovery policy in December 2019 to recover cash and equity compensation from an executive officer in the event we are required to restate our financial results due to material noncompliance with financial reporting requirements and misconduct of the executive officer contributed to such noncompliance.

•Appropriate Compensation Risk. We structure our executive compensation programs to try to minimize the risk of inappropriate risk-taking by our executives.

Advisory Vote on Executive Compensation—“Say-on-Pay” Vote

We conducted an advisory vote on executive compensation, or say-on-pay vote, at our annual meeting of stockholders in 2021. Approximately 96.6% of the votes cast on the say-on-pay proposal supported the proposal. Our Board and our Compensation Committee value the opinions of our stockholders, and we believe that it is important for our stockholders to have an opportunity to vote on this proposal annually, which is consistent with the frequency preferred by our stockholders who voted in 2017. Our Compensation Committee’s decisions regarding compensation for 2021 reflected our say-on-pay vote in 2020. In addition to our annual advisory vote on executive compensation, we are committed to ongoing engagement with our stockholders on executive compensation and corporate governance issues.

Our Compensation Committee has considered the results of the vote in the context of our overall compensation philosophy, policies and decisions. After discussing the levels of support in previous years in favor of the proposals, and considering the Compensation Committee’s continued use of the measures we adopted in response to previous advisory votes to further align management and stockholder interests, including stock ownership guidelines and a performance-based RSU program, our Compensation Committee decided to generally maintain a consistent course for 2022 compensation decisions.

We have sent you these proxy materials because the Board of Directors of Iridium Communications Inc. (sometimes referred to as the Company or Iridium) is soliciting your proxy to vote at the 2022 Annual Meeting of Stockholders, including at any adjournments or postponements of the meeting. You are invited to attend the annual meeting, which will be held exclusively online as described below, to vote on the proposals described in this Proxy Statement. However, you do not need to attend the annual meeting to vote your shares. Instead, you may simply complete, sign, date and return the enclosed proxy card, or follow the instructions below to submit your proxy over the telephone or through the internet.

We intend to mail these proxy materials on or about April 7, 2022 to all stockholders of record entitled to vote at the annual meeting.

HOWDO I ATTENDTHE VIRTUAL ANNUALMEETING?

The meeting will be held exclusively online via a live webcast on May 17, 2022 at 8:30 a.m. Eastern time. Stockholders may attend and participate in the meeting by visiting www.virtualshareholdermeeting.com/IRDM2022. You will not be able to attend the annual meeting in person. To access the annual meeting, you will need the 16-digit control number, which can be found on your proxy card or voting instruction form. The virtual meeting platform is fully supported across browsers and devices running the most updated version of applicable software and plugins. Participants should ensure that they have a strong internet connection if they intend to participate in the virtual meeting.

Whether or not you participate in the annual meeting, it is important that you vote your shares.

We encourage you to access the meeting before the start time. Please allow ample time for online check-in, which will begin at 8:15 a.m. Eastern time on May 17, 2022.

HOWCAN I SUBMIT A QUESTION?

If you would like to submit a question, you may do so during the meeting by logging in to the virtual meeting website at www.virtualshareholdermeeting.com/IRDM2022 using your 16-digit control number, typing your question into the “Ask a Question” field, and clicking “Submit.”

We do not place restrictions on the type or form of questions that may be asked; however, we reserve the right to edit or reject redundant questions or questions that we deem profane or otherwise inappropriate. During the live Q&A session of the annual meeting, we will answer questions as they come in, as time permits, or on the “Investors” page of our website as soon as is practical after the meeting. Stockholders will be limited to one question each unless time otherwise permits.

If you login as a guest, you will not be able to vote your shares or ask questions during the meeting.

WHY IS THE ANNUAL MEETING A VIRTUAL, ONLINE MEETING?

We are again conducting our annual meeting solely online via the internet. We began this practice primarily due to COVID-19 restrictions, but we also believe that a virtual meeting provides greater accessibility for stockholders, encourages stockholder participation from around the world, and improves our ability to communicate more effectively with our stockholders during the meeting. At our first virtual annual meeting in 2020, we had record stockholder attendance, and we had a similar level of attendance at our 2021 virtual meeting. In addition, we eliminate many of the costs associated with a physical meeting.

WHAT IF I HAVE TECHNICAL DIFFICULTIES OR TROUBLE ACCESSING THE VIRTUAL MEETING?

We will have technicians ready to assist you with any technical difficulties you may have accessing the virtual meeting. If you encounter any difficulties accessing the virtual meeting during the check-in or meeting time, please call the technical support number that will be posted on the virtual meeting log-in page.

If you would like to vote your shares during the meeting, please follow the instructions at www.virtualshareholdermeeting.com/IRDM2022. You will need the 16-digit control number, which can be found on your proxy card or voting instruction form. Whether or not you plan to attend the meeting, we urge you to vote by proxy to ensure your vote is counted. You may still attend the virtual meeting and vote online even if you have already voted by proxy. To vote prior to the meeting, you may vote by:

•Mail: Complete, sign, date and mail the enclosed proxy card in the envelope provided, as soon as possible. If you return your signed proxy card to us before the annual meeting, we will vote your shares as you direct.

•Telephone: Call toll-free 1-800-690-6903 using a touch-tone phone and follow the recorded instructions. You will be asked to provide the company number and control number from the enclosed proxy card. Your vote must be received by 11:59 p.m. Eastern time on May 16, 2022 to be counted.

Beneficial Owner: Shares Registered in the Name of Broker or Bank

If you are a beneficial owner of shares registered in the name of your broker, bank or other agent, you should have received a proxy card and voting instructions with these proxy materials from that organization rather than from us. Simply complete, sign, date and mail the proxy card to ensure that your vote is counted. Alternatively, you may vote by telephone or the internet as instructed by your broker or bank. To vote online at the virtual annual meeting, please follow the instructions at www.virtualshareholdermeeting.com/IRDM2022. You will need the 16-digit control number, which can be found on your proxy card or voting instruction form. Whether or not you plan to attend the meeting, we urge you to vote by proxy to ensure your vote is counted. You may still attend the virtual annual meeting and vote online even if you have already voted by proxy.

We provide internet proxy voting to allow you to vote your shares online, with procedures designed to ensure the authenticity and correctness of your proxy vote instructions. However, please be aware that you must bear any costs associated with your internet access, such as usage charges from internet access providers and telephone companies.

HOWMANYVOTESDO I HAVE?

On each matter to be voted upon, you have one vote for each share of common stock you owned at the close of business on March 21, 2022.

IF I AM A STOCKHOLDER OF RECORD AND I DONOTVOTE, OR IF I RETURN A PROXY CARD OR OTHERWISE VOTE WITHOUT GIVING SPECIFIC VOTING INSTRUCTIONS, WHAT HAPPENS?

If you are a stockholder of record and do not vote by completing your proxy card, calling the telephone number, accessing the electronic proxy card on the internet or online at the annual meeting, your shares will not be voted, nor will your shares count toward the establishment of a quorum for the meeting.

If you return a signed and dated proxy card or otherwise vote without marking voting selections, your shares will be voted, as applicable, “For” the election of all thirteen nominees for director, “For” the advisory approval of executive compensation, and “For” the ratification of the selection by the Board of Directors of KPMG LLP as our independent registered public accounting firm for our fiscal year ending December 31, 2022. If any other matter is properly presented at the meeting, your proxyholder (one of the individuals named on your proxy card) will vote your shares using his or her best judgment.

7

IF I AM A BENEFICIAL OWNER OF SHARES HELD IN STREET NAME AND I DO NOT PROVIDE MY BROKER OR BANK WITH VOTING INSTRUCTIONS, WHAT HAPPENS?

If you are a beneficial owner of shares held in street name and you do not instruct your broker, bank or other agent how to vote your shares, your broker, bank or other agent may still be able to vote your shares at its discretion. Under the rules of the New York Stock Exchange, or NYSE, brokers, banks and other securities intermediaries that are subject to NYSE rules may use their discretion to vote your “uninstructed” shares with respect to matters considered to be “routine” under NYSE rules, but not with respect to “non-routine” matters. In this regard, Proposals 1 and 2 are considered to be “non-routine” under NYSE rules, meaning that your broker may not vote your shares on those proposals in the absence of your voting instructions. However, Proposal 3 is considered to be a “routine” matter under NYSE rules, meaning that if you do not return voting instructions to your broker by its deadline, your shares may be voted by your broker in its discretion on Proposal 3.

If you are a beneficial owner of shares held in street name, in order to ensure your shares are voted in the way you would prefer, you must provide voting instructions to your broker, bank or other agent by the deadline provided in the materials you receive from your broker, bank or other agent or vote online at the virtual annual meeting.

WHOISPAYINGFORTHISPROXYSOLICITATION?

We will pay for the entire cost of soliciting proxies. In addition to these proxy materials, our directors and employees and Georgeson LLC, or Georgeson, may also solicit proxies in person, by telephone, or by other means of communication. Directors and employees will not be paid any additional compensation for soliciting proxies, but Georgeson will be paid its customary fee of approximately $8,500 plus out-of-pocket expenses if it solicits proxies. We may also reimburse brokerage firms, banks and other agents for the cost of forwarding proxy materials to beneficial owners.

WHATDOESITMEANIF I RECEIVEMORETHANONESETOFPROXYMATERIALS?

If you receive more than one set of proxy materials, your shares may be registered in more than one name or in different accounts. Please follow the voting instructions on the proxy cards in the proxy materials to ensure that all of your shares are voted.

CAN I CHANGEMYVOTEAFTERSUBMITTINGMYPROXY?

Yes. You can revoke your proxy at any time before the final vote at the meeting. If you are the record holder of your shares, you may revoke your proxy in any one of the following ways:

•You may submit another properly completed proxy card with a later date.

•You may grant a subsequent proxy by telephone or the internet.

•You may send a timely written notice that you are revoking your proxy to our Secretary at 1750 Tysons Boulevard, Suite 1400, McLean, Virginia 22102.

•You may attend the virtual annual meeting and vote online during the meeting. However, simply attending the virtual meeting will not, by itself, revoke your proxy.

Your most recent proxy card or telephone or internet proxy is the one that is counted.

If your shares are held by your broker, bank or other agent, you should follow the instructions provided by that organization for changing your vote or vote online at the virtual annual meeting.

WHENARESTOCKHOLDERPROPOSALSANDDIRECTORNOMINATIONSDUEFORNEXTYEAR’SANNUALMEETING?

To be considered for inclusion in next year’s proxy materials, your proposal must be submitted in writing by December 8, 2022 to our Secretary at 1750 Tysons Boulevard, Suite 1400, McLean, Virginia 22102. If you wish to submit a proposal to be acted on at next year’s annual meeting but not included in next year’s proxy materials, or if you wish to nominate a director, you must provide written notice as required by our bylaws no earlier than the close of business on January 17, 2023 and no later than the close of business on February 16, 2023 to our Secretary at 1750 Tysons Boulevard, Suite 1400, McLean, Virginia 22102. Your notice to the Secretary must set forth information specified in our bylaws, including your name and address and the class and number of shares of our stock that you beneficially own.

If you propose to nominate an individual for election as a director, your notice must also include, as to each person you propose to nominate for election as a director, the following: (1) the name, age, business address and residence address of the person, (2) the principal occupation or employment of the person, (3) the class and number of shares of our stock that are owned of record and beneficially owned by the person, (4) the date or dates on which the shares were acquired and the investment intent of the acquisition and (5) any other information concerning the person as would be required to be disclosed in a proxy statement soliciting proxies for the election of that person as a director in an election contest (even if an election contest is not involved), or that is otherwise required to be disclosed pursuant to Section 14 of the Securities Exchange Act of 1934, or the Exchange Act, and the rules and regulations promulgated under the Exchange Act, including the person’s written consent to being named as a nominee and to serving as a director if elected. We may require any proposed nominee to furnish other information as we may reasonably require to determine the eligibility of the proposed nominee to serve as an independent director or that could be material to a reasonable stockholder’s understanding of the independence, or lack of independence, of the proposed nominee.

For more information, you are advised to review our amended and restated bylaws, filed with the SEC as an exhibit to a current report on Form 8-K on May 15, 2015 (and also incorporated by reference and available by hyperlink as Exhibit 3.3 to our Annual Report on Form 10-K for the year ended December 31, 2021, filed with the SEC on February 17, 2022).

Votes will be counted by the inspector of election appointed for the meeting, who will separately count, for Proposal 1 to elect directors, votes “For,” “Withhold” and broker non-votes; and, with respect to Proposals 2 and 3, votes “For” and “Against,” abstentions and, if applicable, broker non-votes. Abstentions will be counted towards the vote total for Proposals 2 and 3, and will have the same effect as “Against” votes on those proposals. Broker non-votes will have no effect on Proposals 1 and 2, and will not be counted towards the vote total for those proposals.

WHATARE “BROKERNON-VOTES”?

As discussed above, when a beneficial owner of shares held in “street name” does not give instructions to his or her broker, bank or other securities intermediary holding his or her shares as to how to vote on matters deemed to be “non-routine” under the NYSE rules, the broker, bank or other such agent cannot vote the shares. These unvoted shares are counted as “broker non-votes.” Proposals 1 and 2 are considered to be “non-routine” under NYSE rules, and we therefore expect broker non-votes to exist in connection with these proposals.

As a reminder, if you are a beneficial owner of shares held in street name, in order to ensure your shares are voted in the way you would prefer, you must provide voting instructions to your broker, bank or other agent by the deadline provided in the materials you receive from your broker, bank or other agent or vote online at the virtual annual meeting.

HOWMANYVOTESARENEEDEDTOAPPROVEEACHPROPOSAL?

•For Proposal 1, the election of directors, the thirteen nominees receiving the most “For” votes (from the holders of shares present at the meeting or represented by proxy and entitled to vote on the election of directors) will be elected. Only votes “For” or “Withhold” will affect the outcome.

•To be considered to have been approved, Proposal 2, the advisory approval of the compensation of our named executive officers, must receive “For” votes from the holders of a majority of shares present at the meeting or represented by proxy and entitled to vote on the matter. If you “Abstain” from voting, it will have the same effect as an “Against” vote. Broker non-votes will have no effect.

•To be approved, Proposal 3, the ratification of the selection by the Board of Directors of KPMG LLP as our independent registered public accounting firm for our fiscal year ending December 31, 2022, must receive “For” votes from the holders of a majority of shares present at the meeting or represented by proxy and entitled to vote on the matter. If you “Abstain” from voting, it will have the same effect as an “Against” vote.

WHATISTHEQUORUMREQUIREMENT?

A quorum of stockholders is necessary to hold a valid meeting. A quorum will be present if stockholders holding at least a majority of the outstanding shares of common stock entitled to vote are present at the meeting online or represented by proxy. On the record date, there were 128,029,246 shares outstanding and entitled to vote. Thus, the holders of 64,014,624 shares of common stock must be present or represented by proxy at the meeting to have a quorum.

9

Your shares will be counted towards the quorum only if you submit a valid proxy (or one is submitted on your behalf by your broker, bank or other nominee) or if you vote online during the meeting. Abstentions and broker non-votes will be counted towards the quorum requirement. If there is no quorum, the holders of a majority of shares present at the meeting or represented by proxy may adjourn the meeting to another date.

PROPOSAL 1

ELECTION OF DIRECTORS

Our Board of Directors currently consists of thirteen directors, and there are thirteen nominees for director this year. Each director to be elected and qualified will hold office until the next annual meeting of stockholders and until his or her successor is elected, or, if sooner, until the director’s death, resignation or removal. Each of the nominees listed below, except for Ms. Sears, is currently a director who was previously elected by our stockholders at our 2021 annual meeting. Ms. Sears was recommended for nomination to our Board by a third-party search firm. One of our current directors, Steven Pfeiffer, is not standing for re-election at the annual meeting, and his term as a director will end at the conclusion of the annual meeting. It is our policy to encourage nominees for director to attend the annual meeting. All of our directors who were then serving attended the 2021 annual meeting.

Directors are elected by a plurality of the votes of the holders of shares present virtually at the meeting or represented by proxy and entitled to vote on the election of directors. Proxies may not be voted for more than thirteen nominees. The thirteen nominees receiving the highest number of affirmative votes will be elected. Shares represented by executed proxies will be voted, if authority to do so is not withheld, for the election of the thirteen nominees named below. If any nominee becomes unavailable for election as a result of an unexpected occurrence, your shares will be voted for the election of a substitute nominee proposed by us. Each person nominated for election has agreed to serve if elected. Our management has no reason to believe that any nominee will be unable to serve.

Our Corporate Governance Guidelines provide that any nominee who receives a greater number of votes “withheld” than votes “for” must submit an offer of resignation to our Nominating and Corporate Governance Committee. The committee will consider the facts and circumstances and recommend to the Board of Directors the action to be taken with respect to such offer of resignation. The Board of Directors will then act on the committee’s recommendation.

NOMINEES

The Nominating and Corporate Governance Committee of our Board seeks to assemble a board that, as a whole, possesses the appropriate balance of professional and industry knowledge, financial expertise and high-level management experience necessary to oversee and direct our business. To that end, the Nominating and Corporate Governance Committee has identified and evaluated nominees in the broader context of the Board’s overall composition, with the goal of recruiting a diverse group of members who complement and strengthen the skills of other members and who also exhibit integrity, collegiality, sound business judgment and other qualities that the Nominating and Corporate Governance Committee views as critical to effective functioning of the Board.

The biographies below include information, as of the date of this Proxy Statement, regarding the specific and particular experience, qualifications, attributes or skills of each nominee that led the Nominating and Corporate Governance Committee to recommend that person as a nominee for director. However, each member of the committee may have a variety of reasons why he or she believes a particular person would be an appropriate nominee for the Board, and these views may differ from the views of other members.

THE BOARD OF DIRECTORS RECOMMENDS

A VOTE “FOR” EACH NAMED NOMINEE.

INFORMATION REGARDING THE BOARD OF DIRECTORS AND COMMITTEES

AND CORPORATE GOVERNANCE

DIRECTOR INDEPENDENCE

As required under Nasdaq listing standards, a majority of the members of a listed company’s board of directors must qualify as “independent,” as affirmatively determined by its board of directors. The Board consults with our counsel to ensure that the Board’s determinations are consistent with relevant securities and other laws and regulations regarding the definition of “independent,” including those set forth in pertinent Nasdaq listing standards, as in effect from time to time.

Consistent with these considerations, after review of all relevant identified transactions or relationships between each director, or any of his or her family members, and us, our senior management and our independent registered public accounting firm, the Board has affirmatively determined that the following ten director nominees are independent within the meaning of the applicable Nasdaq listing standards: Messrs. Canfield, Frazier, Krongard, Niehaus, Olson, Rush, Schliemann and West and Mses. Harman and Sears. In making these determinations, the Board found that none of these directors had a material or other disqualifying relationship with us. Messrs. Desch and Fitzpatrick and Ms. McBride are not independent directors by virtue of their positions as our executive officers. We believe that service by these executive officers on our Board allows us to consider a broad range of opinions in the course of our Board deliberations, including from those with knowledge of our day-to-day operations and business strategy. Additionally, our independent directors meet in executive session without management present at the end of all regularly scheduled Board meetings. Each of our Audit, Compensation, and Nominating and Corporate Governance Committees is 100% comprised of independent directors.

BOARD LEADERSHIP STRUCTURE

Our Board of Directors has an independent Chairman, Mr. Niehaus, who has authority, among other things, to call and preside over Board meetings, including meetings of the independent directors, to set meeting agendas and to determine materials to be distributed to the Board. Accordingly, the Chairman has substantial ability to shape the work of the Board. We believe that separation of the positions of Chairman and chief executive officer reinforces the independence of the Board in its oversight of our business and affairs. In addition, we believe that having an independent Chairman creates an environment that is more conducive to objective evaluation and oversight of management’s performance, increasing management accountability and improving the ability of the Board to monitor whether management’s actions are in the best interests of us and our stockholders. As a result, we believe that having an independent Chairman can enhance the effectiveness of the Board as a whole.

ROLEOFTHE BOARDIN RISK OVERSIGHT

One of the Board’s key functions is informed oversight of our risk management process. The Board does not have a standing risk management committee, but rather administers this oversight function directly through the Board as a whole, as well as through various Board standing committees that address risks inherent in their respective areas of oversight. As part of its independent oversight of the risks facing the Company, the Board devotes time and attention annually to cybersecurity and cyber incident preparedness and response. In particular, while our Board is responsible for monitoring and assessing strategic risk exposure, our standing committees have the following specific roles in risk management.

15

•Our Audit Committee has the responsibility to consider and discuss our major financial risk exposures and the steps our management has taken to monitor and control these exposures, including guidelines and policies to govern the process by which risk assessment and management is undertaken. Our Audit Committee also monitors compliance with legal and regulatory requirements.

•Our Nominating and Corporate Governance Committee monitors the effectiveness of our corporate governance guidelines, including whether they are successful in preventing illegal or improper liability-creating conduct, and oversees material environmental, social and governance risks.

•Our Compensation Committee assesses and monitors whether any of our compensation policies and programs has the potential to encourage excessive risk-taking. It is the responsibility of the committee chairs to report findings regarding material risk exposures to the Board.

The Chairman of the Board has the responsibility of coordinating between the Board and management with regard to the determination and implementation of responses to any problematic risk management issues.

MEETINGSOFTHE BOARDOF DIRECTORS

The Board of Directors met four times during 2021. Each Board member attended 75% or more of the aggregate number of meetings of the Board and of the committees on which he or she served that were held during the portion of the year for which he or she was a director or committee member. At each meeting, the Board of Directors holds a regularly scheduled executive session at which only independent directors are present.

INFORMATION REGARDING COMMITTEESOFTHE BOARDOF DIRECTORS

Our Board has committees that include an Audit Committee, a Compensation Committee and a Nominating and Corporate Governance Committee. The following table provides current membership and meeting information for 2021 for each of these Board committees:

Audit Committee

The Audit Committee of our Board of Directors was established by the Board to oversee our corporate accounting and financial reporting processes and audits of our financial statements. For this purpose, the Audit Committee performs several functions. The Audit Committee evaluates the performance of, and assesses the qualifications of, the independent registered public accounting firm; determines and approves the engagement of the independent registered public accounting firm; determines whether to retain or terminate the existing independent registered public accounting firm or to appoint and engage a new independent registered public accounting firm; reviews and approves the retention of the independent registered public accounting firm to perform any proposed permissible non-audit services; monitors the rotation of partners of the independent registered public accounting firm on our audit engagement team as required by law; reviews and approves or rejects transactions between us and any related persons; confers with management and the independent registered public accounting firm regarding the effectiveness of internal controls over financial reporting; establishes procedures, as required under applicable law, for the receipt, retention and treatment of complaints received by us regarding accounting, internal accounting controls or auditing matters and the confidential and anonymous submission by employees of concerns regarding questionable accounting or auditing matters; and meets to review our annual audited financial statements and quarterly financial statements with management and the independent registered public accounting firm, including a review of our disclosures under “Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

The Audit Committee is currently composed of Messrs. Rush (Chairman), Canfield, Frazier and Schliemann. In 2021, the Audit Committee met four times. The Audit Committee has adopted a written charter that is available to stockholders on our website at http://investor.iridium.com/corporate-governance.

At least annually, the Board of Directors reviews the Nasdaq listing standards definition of independence for Audit Committee members and has determined that all current members of our Audit Committee are independent (as independence is currently defined in Rule 5605(c)(2)(A)(i) and (ii) of the Nasdaq listing standards). The Board of Directors has also determined that each of Messrs. Rush, Frazier and Schliemann qualifies as an “audit committee financial expert,” as defined in applicable SEC rules. The Board made a qualitative assessment of each such member's level of knowledge and experience based on a number of factors, including (i) in the case of Mr. Rush, his formal education and experience as the President and Chief Executive Officer of a public reporting company, (ii) in the case of Mr. Frazier, his formal education and experience managing financial oversight of a reporting segment of a public company, and (iii) in the case of Mr. Schliemann, his formal education and experience as Chief Executive Officer of a financial advisory firm.

Report of the Audit Committee of the Board of Directors

The Audit Committee reviewed and discussed the audited financial statements for the year ended December 31, 2021 with management of Iridium Communications Inc. The Audit Committee discussed with the independent registered public accounting firm the matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board, or PCAOB, and the Securities and Exchange Commission. The Audit Committee received the written disclosures and the letter from the independent registered public accounting firm required by applicable requirements of the PCAOB regarding the independent accountants’ communications with the audit committee concerning independence, and discussed with the independent registered public accounting firm the accounting firm’s independence. Based on the foregoing, the Audit Committee recommended to the Board of Directors that the audited financial statements be included in the Annual Report on Form 10-K for the fiscal year ended December 31, 2021.

Compensation Committee

Our Compensation Committee is currently composed of Messrs. Pfeiffer (Chairman), Krongard, Niehaus, Olson and West. Mr. Pfeiffer's term as a director and chairman of the Compensation Committee will end at the conclusion of the annual meeting, following which Adm. Olson will become the chairman. If elected at the annual meeting, Ms. Sears is expected to be appointed to the Compensation Committee. All of the current and proposed members of our Compensation Committee following the annual meeting are independent within the meaning of the Nasdaq listing standards (as independence is currently defined in Rule 5605(d)(2) of the Nasdaq listing standards). In 2021, the Compensation Committee met five times. The Compensation Committee has adopted a written charter that is available to stockholders on our website at https://investor.iridium.com/corporate-governance.

The Compensation Committee acts on behalf of the Board to oversee our compensation policies, plans and programs, including with respect to salary, annual bonuses, long-term equity incentives, perquisites, severance arrangements, retirement benefits and other employee benefits, and to review and determine the compensation to be paid to our executive officers and directors.

Our Compensation Committee also reviews with management our Compensation Discussion and Analysis and considers whether to approve its inclusion in proxy statements and other filings.

Typically, the Compensation Committee meets quarterly and with greater frequency if necessary. The agenda for each meeting is usually developed by the Chairman of the Compensation Committee. The Compensation Committee meets regularly in executive session. However, various members of management and other employees as well as outside advisors or consultants may be invited by the Compensation Committee to make presentations, to provide financial or other background information or advice or to otherwise participate in Compensation Committee meetings. Our chief executive officer may not participate in, or be present during, any deliberations or determinations of the Compensation Committee regarding his compensation or individual performance objectives. The charter of the Compensation Committee grants the Compensation Committee full access to all of our books, records, facilities and personnel, as well as authority to obtain, at our expense, advice and assistance from internal and external legal, accounting or other advisors and consultants and other external resources that the Compensation Committee considers necessary or appropriate in the performance of its duties. In particular, the Compensation Committee has the sole authority to retain compensation consultants to assist in its evaluation of executive and director compensation, including the authority to approve the consultant’s reasonable fees and other retention terms. Under its charter, the Compensation Committee may select, or receive advice from, a compensation consultant, legal counsel or other advisor to the Compensation Committee, other than in-house legal counsel and certain other types of advisors, only after taking into consideration six factors, prescribed by the SEC and Nasdaq, that bear upon the advisor’s independence; however, there is no requirement that any advisor be independent.

During 2021, after taking into consideration the six factors prescribed by the SEC and Nasdaq described above, our Compensation Committee engaged the compensation consultant, Radford, which is part of the Rewards Solutions practice at Aon plc, to perform the services described in “Executive Compensation—Compensation Discussion and Analysis—Use of Compensation Consultant.”

The specific determinations of our Compensation Committee with respect to executive compensation for the year ended December 31, 2021 are described in greater detail in the “Compensation Discussion and Analysis” section of this Proxy Statement.

Nominating and Corporate Governance Committee

The Nominating and Corporate Governance Committee of the Board of Directors is responsible for identifying, reviewing and evaluating candidates to serve as our directors, consistent with criteria approved by the Board, reviewing and evaluating incumbent directors, recommending to the Board for selection candidates for election to the Board of Directors, making recommendations to the Board regarding the membership of the committees of the Board, assessing the performance of the Board, reviewing succession planning for executive officers, developing corporate governance principles for us and overseeing material ESG matters.

The Nominating and Corporate Governance Committee is composed of Messrs. Krongard (Chairman), Canfield and Schliemann and Ms. Harman. All members of the Nominating and Corporate Governance Committee are independent within the meaning of the Nasdaq listing standards (as independence is currently defined in Rule 5605(a)(2) of the Nasdaq listing standards).

During 2021, the Nominating and Corporate Governance Committee met four times. The Nominating and Corporate Governance Committee has adopted a written charter that is available to stockholders on our website at: http://investor.iridium.com/corporate-governance.

The Nominating and Corporate Governance Committee believes that candidates for director should have minimum qualifications, including having the ability to read and understand basic financial statements, being over 22 years of age and having the highest personal integrity and ethics. The Nominating and Corporate Governance Committee also intends to consider other factors, such as possessing relevant expertise upon which to be able to offer advice and guidance to management, having sufficient time to devote to our affairs, demonstrated excellence in his or her field, having the ability to exercise sound business judgment and having the commitment to rigorously represent the long-term interests of our stockholders. However, the Nominating and Corporate Governance Committee can modify these qualifications from time to time. Candidates for director nominees are reviewed in the context of the current composition of the Board, our operating requirements and the long-term interests of stockholders. In conducting this assessment, the Nominating and Corporate Governance Committee typically considers diversity, age, skills and such other factors as it deems appropriate given our current needs and those of the Board to maintain a balance of knowledge, experience and capability.

In the case of incumbent directors, the Nominating and Corporate Governance Committee annually reviews these directors’ overall service to us during their terms, including the number of meetings attended, level of participation, quality of performance and any other relationships and transactions that might impair the directors’ independence. In the case of new director candidates, the Nominating and Corporate Governance Committee also determines whether the nominee is independent for Nasdaq purposes, which determination is based upon applicable Nasdaq listing standards, applicable SEC rules and

19

regulations and the advice of counsel, if necessary. The Nominating and Corporate Governance Committee uses its network of contacts, as well as those of senior management, to compile a list of potential candidates, but may also engage, if it deems appropriate, a professional search firm. The Nominating and Corporate Governance Committee conducts any appropriate and necessary inquiries into the backgrounds and qualifications of possible candidates after considering the function and needs of the Board. The Nominating and Corporate Governance Committee meets to discuss and consider the candidates’ qualifications and then recommends candidates to the Board for selection. In fiscal 2021, the Nominating and Corporate Governance Committee paid a fee to Heidrick & Struggles International, Inc. to assist in the process of identifying or evaluating director candidates, which resulted in the nomination of Ms. Sears for election at the annual meeting.

The Nominating and Corporate Governance Committee will consider director candidates recommended by stockholders. The Nominating and Corporate Governance Committee does not intend to alter the manner in which it evaluates candidates, including the minimum criteria set forth above, based on whether or not the candidate was recommended by a stockholder. Stockholders who wish to recommend individuals for consideration by the Nominating and Corporate Governance Committee to become nominees for election to the Board may do so by delivering a written recommendation to the Nominating and Corporate Governance Committee at the following address: c/o Iridium Communications Inc., 1750 Tysons Blvd., Suite 1400, McLean, VA 22102, Attn: Secretary, not less than 90 days but not more than 120 days prior to the anniversary date of the last annual meeting of stockholders. Submissions must include the name and address of the stockholder making the recommendation, the number of shares of our common stock beneficially owned by such stockholder as of the date of the submission, the full name of the proposed nominee, a description of the proposed nominee’s business experience for at least the previous five years, complete biographical information for the nominee and a description of the proposed nominee’s qualifications as a director. Any such submission must be accompanied by the written consent of the proposed nominee to be named as a nominee and to serve as a director if elected.

Stockholder Communications with the Board of Directors

Our Board has adopted a formal process by which stockholders may communicate with the Board or any of its directors. Stockholders who wish to communicate with the Board or an individual director may send a written communication to the Board or such director addressed to our Secretary at 1750 Tysons Blvd., Suite 1400, McLean, VA 22102. Each communication must set forth:

•the name and address of the stockholder on whose behalf the communication is sent; and

•the number of our shares that are owned beneficially by such stockholder as of the date of the communication.

Each communication will be reviewed by our Secretary to determine whether it is appropriate for presentation to the Board or such director. Examples of inappropriate communications include advertisements, solicitations or hostile communications. Communications determined by our Secretary to be appropriate for presentation to the Board or such director will be submitted to the Board or such director on a periodic basis.

Code of Ethics

We have adopted the Iridium Communications Inc. Code of Business Conduct and Ethics, or the Code of Ethics, that applies to all of our officers, directors and employees as well as those of our subsidiaries. The Code of Ethics is available on our website at http://investor.iridium.com/corporate-governance. If we make any substantive amendments to the Code of Ethics, or grant any waiver from a provision of the Code of Ethics to any executive officer or director, we will promptly disclose the nature of the amendment or waiver on our website.

20

Corporate Governance Guidelines

The Board of Directors has documented our governance practices by adopting Corporate Governance Guidelines, or the Guidelines, to assure that the Board will have the necessary authority and practices in place to review and evaluate our business operations as needed and to make decisions that are independent of our management. The Guidelines are also intended to align the interests of directors and management with those of our stockholders. The Guidelines set forth, among other things, the practices the Board intends to follow with respect to Board composition and selection, Board meetings and involvement of senior management, chief executive officer performance evaluation and succession planning, and Board committees and compensation. The Guidelines provide that any nominee who receives a greater number of votes “withheld” than votes “for” must submit an offer of resignation to our Nominating and Corporate Governance Committee. The committee will consider the facts and circumstances and recommend to the Board of Directors the action to be taken with respect to such offer of resignation, and the Board of Directors will then act on the committee’s recommendation. The Guidelines are available on our website at http://investor.iridium.com/corporate-governance.

ENVIRONMENTAL, SOCIAL AND GOVERNANCE (ESG)

The following section highlights certain of our ESG efforts. More information about these efforts can be found in our second annual ESG Report, available in the corporate social responsibility section of our website, https://www.iridium.com/csr/.

Our Approach to Environmental, Social and Governance Issues

Our products and services have always been designed with purpose. We strive to set an example of high standards of corporate citizenship through our mission-driven technology coupled with our support for disaster preparedness and relief, education, and philanthropy.

At Iridium, we recognize our global impact and extend our responsibility to the environments and communities in which we work and operate. Our ESG reporting and disclosure align with the ESG topics that the Sustainability Accounting Standards Board (SASB) has determined are most relevant to the financial performance of our industry. We also reference the Global Reporting Initiative (GRI) to provide additional ESG disclosure topics and have begun to align our ESG strategy to United Nations (U.N.) Sustainable Development Goals (SDGs).

Sustainability governance starts at the top with our Board of Directors. Specifically, as discussed above, the Nominating and Corporate Governance Committee has the oversight responsibility to review our ESG policies and initiatives that may have relevance to our financial performance, business activities or reputation. The responsibility for implementing Iridium’s ESG strategy and day-to-day management has been delegated to a cross-functional working group represented by investor relations; finance and IT; legal; and marketing and communications.

Environmental Impact

With increased attention on climate change in recent years, we are proud that our technology enables research, monitoring and communications for organizations tackling some of the most challenging environmental issues. From climate change monitoring to carbon footprint reduction and wildlife protection, our solutions are designed to help our users make the world a safer, cleaner place. When it comes to our satellite network, we are also committed to keeping space clean and aim to help develop and maintain industry standards for satellite management and space debris mitigation.

We strive to innovate so that our phones and other products have greater power and battery life, decreased material use, and increased energy efficiency than ever before. Additionally, we support disaster relief efforts around the country and internationally on a broad scale. Our satellite phones and Iridium GO!® devices are used for communication in areas undergoing crisis or natural disasters. Devices connected by our satellites also work to gather ocean pressure data to aid the prediction of the onset of tsunamis.

Human Capital Management and Diversity, Equity and Inclusion

We strive to create an innovative and inclusive environment where our employees are proud to work, feel safe, and can bring their full selves to their efforts. Toward those ends, we focus on development, engagement, employee wellness and social responsibility.

We recognize that diversity of thought, culture and perspective is not only essential to creating a successful global communications system but is also imperative to creating an inclusive, collaborative and productive work environment. We aim to employ, maintain and advance employees with backgrounds that represent the reach of our system.

21

In 2020, we launched our Diversity and Inclusion Council with a mission to inspire those we work with, for and around to make our community and the world a more diverse and inclusive place. Our CEO is the co-chair of the Council and continues to oversee our diversity, equity and inclusion (DEI) standards and expectations.

We also consider the health, safety and well-being of our employees. The COVID-19 pandemic has dramatically changed the way that we operate and how our employees live and work. We initially transitioned our workforce to work from home and have now moved to a hybrid model, except for employees needing in-person access to laboratories or other resources onsite. We believe that we have learned to operate successfully in this new environment, and we remain committed to supporting our new, more carbon-friendly, hybrid work program for our team. Our COVID-19 task force continues to monitor CDC guidelines and communicates frequently with employees about recent developments and actions.

PROPOSAL 2

ADVISORY VOTE ON EXECUTIVE COMPENSATION

At our 2017 annual meeting of stockholders, our stockholders indicated their preference that we solicit a non-binding advisory vote on the compensation of our named executive officers, commonly referred to as a “say-on-pay” vote, every year. The Board has adopted a policy that is consistent with that preference. In accordance with that policy, this year we are again asking our stockholders to approve, on an advisory basis, the compensation of our named executive officers as disclosed in this Proxy Statement in accordance with SEC rules.

This vote is not intended to address any specific item of compensation, but rather the overall compensation of our named executive officers and the compensation philosophy, policies and practices described in this Proxy Statement. The compensation of our named executive officers subject to the vote is disclosed in the Compensation Discussion and Analysis, the compensation tables and the related narrative disclosure contained in this Proxy Statement. As discussed in those disclosures, we believe that our compensation policies and decisions are focused on pay-for-performance principles and strongly aligned with our stockholders’ interests. Compensation of our named executive officers is designed to enable us to attract, motivate and retain talented and experienced executives to lead our company successfully in a competitive environment.

Accordingly, the Board is asking stockholders to indicate their support for the compensation of our named executive officers as described in this Proxy Statement by casting a non-binding advisory vote “FOR” the following resolution:

“RESOLVED, that the compensation paid to the Company’s named executive officers, as disclosed pursuant to compensation disclosure rules of the Securities and Exchange Commission, including the Compensation Discussion and Analysis, compensation tables and any related information disclosed in this Proxy Statement, is hereby APPROVED.”

Because the vote is advisory, it is not binding on us or the Board of Directors. Nevertheless, the views expressed by our stockholders, whether through this vote or otherwise, are important to management and the Board and, accordingly, the Board and the Compensation Committee intend to consider the results of this vote in making determinations in the future regarding executive compensation arrangements.

Advisory approval of this proposal requires the vote of the holders of a majority of the shares present at the meeting or represented by proxy and entitled to vote on the matter at the annual meeting. Abstentions will be counted toward the tabulation of votes cast on proposals presented to the stockholders and will have the same effect as negative votes. Broker non-votes are counted towards a quorum, but are not counted for any purpose in determining whether this matter has been approved.

Unless the Board decides to modify its policy regarding the frequency of soliciting advisory votes on the compensation of our named executive officers, the next scheduled say-on-pay vote will be at the 2023 annual meeting of stockholders. The next advisory vote on the frequency of solicitation of advisory stockholder approval of executive compensation will also be at the 2023 annual meeting of stockholders.

THE BOARD OF DIRECTORS RECOMMENDS

A VOTE “FOR” PROPOSAL 2.

PROPOSAL 3

RATIFICATIONOF SELECTIONOF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors has selected KPMG LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2022 and has further directed that management submit the selection of the independent registered public accounting firm for ratification by stockholders at the annual meeting. KPMG LLP has not previously served as our independent registered public accounting firm.

Neither our Bylaws nor other governing documents or law require stockholder ratification of the selection of KPMG LLP as our independent registered public accounting firm. However, the Board of Directors is submitting the selection of KPMG LLP to stockholders for ratification as a matter of good corporate practice. If the stockholders fail to ratify the selection, the Audit Committee will reconsider whether to continue to retain that firm. Even if the selection is ratified, the Audit Committee in its discretion may direct the appointment of different independent auditors at any time during the year if they determine that such a change would be in our best interests and those of our stockholders.

The affirmative vote of the holders of a majority of the shares present at the annual meeting or represented by proxy and entitled to vote on the matter at the meeting will be required to ratify the selection of KPMG LLP. Abstentions will be counted toward the tabulation of votes cast on proposals presented to the stockholders and will have the same effect as negative votes. Broker non-votes are counted towards a quorum, but are not counted for any purpose in determining whether this matter has been approved.

Representatives of KPMG LLP are expected to be present at the virtual annual meeting. They will be available to respond to appropriate questions.

INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FEES

The following table represents aggregate fees billed to us for the fiscal years ended December 31, 2021 and 2020 by Ernst & Young LLP, our independent registered public accounting firm for those years.

	Year Ended December 31,
	2021		2020
Audit fees(1)	$	1,366,667	$	1,277,829
Tax fees(2)	16,848		15,787
Total fees	$	1,383,515	$	1,293,616

_____________________

(1)Fees for audit services include fees associated with the annual audit of our financial statements, the reviews of our interim financial statements included in our quarterly reports on Form 10-Q, statutory audits required by foreign jurisdictions, fees related to consents provided in connection with Form S-8 registration statements, and fees associated with financing activities in 2021.

(2)Consists of fees for tax compliance, tax advice and tax planning.

All fees described above were pre-approved by the Audit Committee.

PRE-APPROVAL POLICYAND PROCEDURES

The Audit Committee has adopted a policy and procedures for the pre-approval of audit and non-audit services rendered by our independent registered public accounting firm. The policy generally requires pre-approval of specified services in the defined categories of audit services, audit-related services and tax services up to specified amounts. Pre-approval may also be given as part of the Audit Committee’s approval of the scope of the engagement of the independent registered public accounting firm or on an individual, explicit, case-by-case basis before the independent registered public accounting firm is engaged to provide each service. The pre-approval of services may be delegated to one or more of the Audit Committee’s members, but the decision must be reported to the full Audit Committee at its next scheduled meeting.

The Audit Committee has determined that the rendering of the services other than audit services by KPMG LLP is compatible with maintaining their independence.

On March 2, 2022, the Audit Committee of the Board of Directors approved the appointment of KPMG LLP as the Company’s independent registered public accounting firm to audit the Company’s financial statements for the fiscal year ending December

24

31, 2022, in place of Ernst & Young LLP (“EY”).The decision to change our accounting firm was authorized by the Audit Committee.

The report of EY on the consolidated financial statements of the Company for the three years ended December 31, 2021, dated February 17, 2022, included in the Form 10-K filed with the SEC on February 17, 2022, did not contain any adverse opinion or disclaimer of opinion and was not qualified as to audit scope or accounting principles.

In connection with the Company’s audits for the fiscal years ended December 31, 2021 and 2020, and in the subsequent period before EY’s dismissal on March 2, 2022, there were no disagreements with EY on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, that would have caused EY to report the disagreement if it had not been resolved to the satisfaction of EY.EY’s reports on the financial statements for the past two years did not contain an adverse opinion or disclaimer of an opinion, nor were they qualified or modified as to uncertainty, audit scope or accounting principles.EY’s letter to the SEC stating its agreement with the statements in this paragraph was filed as an exhibit to the Company’s Current Report on Form 8-K dated March 4, 2022.

During the fiscal years ended December 31, 2021 and 2020 and any subsequent interim period before the Company’s engagement of KPMG, the Company did not consult with KPMG regarding the application of accounting principles to a specified transaction, or the type of audit opinion that might be rendered on the Company’s financial statements.

THE BOARD OF DIRECTORS RECOMMENDS

A VOTE “FOR” PROPOSAL 3.

(1)    Mr. Hickey's employment with us ended on December 31, 2021. We entered into a consulting agreement with Mr. Hickey, effective December 31, 2021, pursuant to which Mr. Hickey will provide consulting services to us through March 31, 2023. See “Thomas D. Hickey Separation Benefits” below for additional information.

We present our Compensation Discussion and Analysis in the following sections:

1. Executive Summary (page 30). In this section, we provide an overview of our business and 2021 performance highlights, discuss certain aspects of our executive compensation program, discuss the response of our Compensation Committee to the 2021 stockholder advisory vote on named executive officer compensation and provide a summary of reported versus realizable and realized equity award compensation for our chief executive officer.

2. Executive Compensation Program (page 34). In this section, we describe our executive compensation philosophy, the use of a compensation consultant and peer group data and the material components of our executive compensation program. We also describe the reasons for providing, and manner of structuring, the key compensation elements in 2021.

3. Other Executive Compensation Matters (page 44). In this section, we provide a brief overview of our policies related to equity compensation grants and prohibition of hedging and pledging transactions involving our stock, minimum stock ownership, change in control, severance and employee benefits, and executive compensation clawbacks. We also review the accounting and tax treatment of compensation and the relationship between our compensation program and risk.

Executive Summary

Business Overview. We are engaged primarily in providing mobile voice and data communications services using a constellation of orbiting satellites. We are the only commercial provider of communications services offering true global coverage, connecting people, organizations and assets to and from anywhere, in real time. Our unique L-band satellite network provides reliable communications services to regions of the world where terrestrial wireless or wireline networks do not exist or are limited, including remote land areas, open ocean, airways, the polar regions and regions where the telecommunications infrastructure has been affected by political conflicts or natural disasters.

We provide voice and data communications services to businesses, the U.S. and foreign governments, non-governmental organizations and consumers via our satellite network, which has an architecture of 66 operational satellites with in-orbit and ground spares and related ground infrastructure. We utilize an interlinked mesh architecture to route traffic across the satellite constellation using radio frequency crosslinks between satellites. This unique architecture minimizes the need for ground facilities to support the constellation, which facilitates the global reach of our services and allows us to offer services in countries and regions where we have no physical presence.

Our second-generation satellite constellation, which we completed in 2019, supports exciting new broadband and midband offerings like Iridium Certus®, innovative new products in Internet of Things, or IoT, like the Iridium Edge® line, and cloud connectivity with Iridium CloudConnect. Our safety service, Iridium® GMDSS for mariners, broke the decades-long monopoly of the maritime safety industry and provides a choice to over 60,000 Safety of Life at Sea, or SOLAS, class vessels that are required by maritime law to maintain this L-band safety service.

30

2021 Business Highlights. We had another strong year in 2021, reporting record total revenue. We achieved this growth even in the face of supply chain issues, while continuing to expand our product portfolio. The resilience of our wholesale business model and double-digit subscriber growth in 2021 are testaments to the strength of our global partner network and the growing demand for Iridium’s safety services and mobility platform.

In 2021, we generated record total revenue of $614.5 million, a 5% year-over-year increase, and ended the year with 1,723,000 worldwide subscribers, a 17% year-over-year increase. This year-end subscriber number includes 147,000 U.S. government subscribers. Driven by continued strength in consumer personal communications devices, our commercial IoT data subscribers grew 24% from the end of 2020 to 1,193,000 customers at the end of 2021, which represented 76% of our commercial customer base at the end of 2021.

In addition to delivering strong subscriber growth and financial performance, we continued to leverage our strong free cash flow position and execute on stockholder-friendly activities in 2021. For example, during 2021 we repurchased $163 million of our common stock through our initial share repurchase program, which allows us to repurchase up to $300 million of our common stock through December 31, 2022, and through March 15, 2022, we have repurchased a total of $298 million of our common stock through this program. In March 2022, our Board of Directors authorized the repurchase of an additional $300 million through December 31, 2023, increasing the potential maximum under this repurchase program to $600 million.

Important Features of our Executive Compensation Program. Our executive compensation program is designed to attract, reward and retain a talented, innovative and entrepreneurial team of executives to fulfill our business objectives. To do so, we believe that a majority of our executives’ target compensation should be based on performance, both of the individual and of our business. We structure our variable compensation programs to recognize both short-term and long-term contributions. The important features of our executive compensation program include:

•Annual Incentives Tied to Performance – Our executive compensation is heavily weighted toward at-risk, performance-based compensation in the form of an annual incentive bonus opportunity that is based on achievement of a combination of financial, strategic and operational goals selected annually by our Compensation Committee and an equity program that is also linked to future performance and continued service. Additionally, we typically pay a portion of each annual incentive bonus granted to our employees, including executives, in the form of equity awards. For 2021, the first 60% of each executive’s target annual incentive bonus award was paid in the form of restricted stock units, or RSUs, that vested only upon the Compensation Committee’s certification of achievement of pre-established performance goals and continued service through the vesting date in March 2022, and the remaining amount was paid in cash.

•Significant Percentages of Compensation At-Risk – As reflected in the charts below, in 2021, at-risk compensation represented approximately 82% of our chief executive officer’s total direct compensation, and an average of 79% of our other named executive officers’ total direct compensation (in each case, as reported in our 2021 Summary Compensation Table). In 2021, at-risk compensation consisted of (1) annual incentive bonus awards paid in RSUs and cash and (2) long-term time-based and performance-based RSU grants.No stock option grants were made to any of our executives during 2021.

31

(1)     Excludes Mr. Hickey, whose employment with us ended on December 31, 2021.

•Performance-Based Equity Awards – Fifty percent of the annual long-term equity-based incentive awards vest only upon the achievement of pre-established performance criteria and, if such performance criteria are met, are subject to additional service-based vesting thereafter.

•Reasonable Cash Severance Amounts – The cash severance benefits that we offer to our executives do not exceed two times their respective base salaries and annual incentive bonus awards.

•No Tax Gross-Up Benefits – We do not provide our executive officers with any excise tax or other tax gross-ups.

•No Pension or SERP Benefits – We do not provide any defined benefit pension plans or supplemental employee retirement plans to our executive officers.

•Meaningful Executive Stock Ownership Guidelines – As further described below, our executives are required to comply with our stock ownership guidelines, which we adopted in 2012. Under these guidelines, our chief executive officer is required to accumulate shares of our common stock with a value equal to four times his annual base salary, and our executive vice presidents, including our chief financial officer, chief operations officer and chief legal officer, are required to accumulate shares of our common stock with a value equal to two times their annual base salaries.

•Prohibition of Hedging and Pledging Transactions – Our insider trading policy prohibits our employees, including our executives, directors and consultants, from hedging or pledging the economic interest in the Iridium shares they hold.

•Use of Independent Compensation Consultant – Our Compensation Committee has retained an independent third-party compensation consultant for guidance in making compensation decisions.

•Use of Peer Group and Market Data – Our Compensation Committee reviews market practices and makes internal comparisons among our executives when making compensation decisions.

•Compensation Recovery Policy – Our Board adopted a compensation recovery policy that allows us to recover both cash and equity compensation from an executive officer in the event we are required to restate our financial results due to material noncompliance with financial reporting requirements and misconduct of the executive officer contributed to such noncompliance.

•Appropriate Compensation Risk – We structure our executive compensation programs to try to minimize the risk of inappropriate risk-taking by our executives.

32

Pay for Performance. Our Compensation Committee applies a pay-for-performance philosophy and structures a significant portion of our named executive officers’ target total direct compensation to be variable, at risk and tied directly to our performance over the short- and long-term. Our 2021 annual incentive bonus plan and performance-based equity award payouts illustrate this core objective. The performance goals for our annual incentive plan and the performance goals for our performance-based RSU program, each as discussed below, were adopted by our Compensation Committee in February 2021. Our chief executive officer and our other executive officers received a payout of 143% of their target bonuses under our 2021 incentive bonus plan. The payout was the result of our exceeding our 2021 operational EBITDA financial target by over $8 million, as well as our achievement of pre-established strategic and operational goals for 2021. Consistent with prior years, the Compensation Committee assigned a greater weight to the operational EBITDA goal in 2021, which represented 65% of the target incentive bonus, with a significant increase for exceeding the operational EBITDA target, scaling up to an additional 65% for achievement at 104.1% of the target level, reflecting the Compensation Committee's judgment of the difficulty of exceeding the target performance level in a year when several of the markets in which the Company operates were expected to remain under significant pressure from the COVID-19 pandemic. Under the terms of our 2021 annual incentive bonus plan, 60% of each executive’s target incentive bonus earned for the 2021 calendar year was paid in the form of shares of our common stock pursuant to RSUs granted under our Amended and Restated 2015 Equity Incentive Plan, or our 2015 Plan, with the remaining amount paid in cash.

Paying a portion of our executives’ target annual incentive bonus awards in the form of equity awards further aligns our compensation program with the interests of our stockholders because the awards only vest based upon achievement of our key corporate objectives and the value of the award can increase or decrease with the value of our stock price.

We also maintain a performance-based RSU program for our executives, including our named executive officers, to further link our equity-based awards to achievement of specific financial performance targets based on service revenue growth and operational EBITDA margin. These awards vest on a sliding scale based on specified achievement levels for these two metrics over a two-year performance period. Since inception of this program in 2012, the percentage of these performance-based RSUs that have vested, as a percentage of the target achievement, by grant year is as follows:

Once the level of performance has been determined for the two-year performance period, these performance-based RSUs are subject to further time-based vesting for retention purposes, with 50% eligible to vest on March 1, shortly after the performance goal achievement is certified, and 50% eligible to vest one year later. We believe that the structure of this program underscores the emphasis on rewarding our executive officers based on actual Company performance. We continue to grant awards under this program because we believe performance-based equity contributes to our goal of heavily weighting executive

33

compensation toward performance-based compensation. The vesting percentage for awards granted in 2021 will be determined in 2023, and for awards granted in 2022, it will be determined in 2024.

During 2021, we also granted long-term incentives in the form of RSUs subject to time-based vesting to align the interests of our executives with those of our stockholders and promote long-term decision-making. The value, if any, that may be realized from these equity awards is directly tied to our stock price performance over a multi-year period, during which time a named executive officer must continue to provide effective and satisfactory services to us for such equity awards to vest.

2021 Say-on-Pay Vote. We conducted an advisory vote on executive compensation, or say-on-pay vote, at our annual meeting of stockholders in 2021. Approximately 96.6% of the votes cast on the say-on-pay proposal supported the proposal. Our Board and our Compensation Committee value the opinions of our stockholders, and we believe that it is important for our stockholders to have an opportunity to vote on this proposal annually, which is consistent with the frequency preferred by our stockholders who voted on the preferred frequency at our stockholder meeting in 2017. Our Compensation Committee’s decisions regarding compensation for 2021 reflected our say-on-pay vote in 2020, which was supported by approximately 96.2% of the votes cast on the proposal. In addition to our annual advisory vote on executive compensation, we are committed to ongoing engagement with our stockholders on executive compensation and corporate governance issues.

Our Compensation Committee has considered the results of the advisory vote in the context of our overall compensation philosophy, policies and decisions. After discussing the levels of support each year in favor of the proposals and considering the Compensation Committee’s continued use of the measures we adopted in response to previous advisory votes to further align management and stockholder interests, including stock ownership guidelines, a performance-based RSU program and adoption of a compensation recovery policy, our Compensation Committee decided to generally maintain a consistent course for 2021 compensation decisions.

Executive Compensation Program

Objectives of Our Compensation Programs

Our executive compensation program emphasizes a total compensation philosophy, focused on pay-for-performance, inclusive of both cash and equity incentives, and a mix of long-term and annual compensation. We design our executive compensation programs to:

•provide a competitive compensation package to attract and retain talented individuals to manage and operate all aspects of our business;

•motivate our executives to achieve corporate and individual objectives that promote the growth and profitability of our business, as measured by objective goals; and

•align the interests of our executive officers with those of our stockholders.

To meet these objectives, we provide fixed base salary, performance-based annual incentives, in both cash and RSUs, performance-based and time-based long-term equity incentive awards, broad-based employee benefits with limited perquisites, and responsible severance benefits. We do not have formal policies for allocating compensation between long-term and currently paid-out compensation, or between cash and non-cash compensation, but rather, the Compensation Committee makes determinations regarding the allocation of compensation based on the best interests of our Company with the goal of encouraging and rewarding performance. Aggregate equity incentive award target values for our executive officers are generally allocated approximately 50% to time-based vesting awards and approximately 50% to awards under our performance-based RSU program to provide retentive value and reward achievement of our corporate strategic objectives.

Role of the Compensation Committee

Our Compensation Committee is generally responsible for reviewing, modifying, approving and otherwise overseeing the compensation policies and practices applicable to all of our employees, including the administration of our equity plans and employee benefit plans. As part of this responsibility, the Compensation Committee establishes, reviews and modifies the compensation structure for our named executive officers. However, the Compensation Committee may, in its discretion and in accordance with the philosophy of making all information available to our Board, present executive compensation matters to the entire Board for its review and approval.

34

As part of its deliberations in any given year, the Compensation Committee may review and consider materials such as studies and reports prepared by a compensation consultant; financial reports and projections; operational data; tax and accounting information that set forth the total compensation that may become payable to executives in various hypothetical scenarios; executive and director stock ownership information; our common stock performance data; analyses of historical executive compensation levels and current Company-wide compensation levels; and the recommendations of our chief executive officer and the Compensation Committee’s independent compensation consultant.

Role of Management

Our Compensation Committee solicits and considers the performance evaluations and compensation recommendations for our named executive officers submitted by our chief executive officer. Generally, our chief executive officer and our chief legal officer attend meetings of the Compensation Committee. The Compensation Committee conducts a formal performance evaluation of each of our named executive officers annually, with informal commentary discussed as needed throughout the year. Our chief executive officer prepares and presents these evaluations and recommendations to our Compensation Committee outside of the presence of any other executive officers. However, our Compensation Committee retains the final authority to make all compensation decisions. Our Compensation Committee meets in executive session after our chief executive officer has reviewed his evaluations and reports back to management on the results of their deliberations.

Our legal, finance and human resources departments work with our chief executive officer to design and develop recommended compensation programs for our named executive officers and other senior executives, to recommend changes to existing compensation programs, to recommend financial and other performance targets to be achieved under those programs, to prepare analyses of financial data, to prepare peer data comparisons and other briefing materials, and ultimately to implement the decisions of the Compensation Committee. Members of our legal department also meet separately with the Compensation Committee’s independent compensation consultant to convey information on proposals that management may make to the Compensation Committee, as well as to allow the consultant to collect information about us to develop its own proposals. No executive officer participated directly in the final determinations of the Compensation Committee regarding the amount of any component of his or her own 2021 compensation package.

Use of Compensation Consultant

In the fall of 2020, our Compensation Committee decided to continue its engagement of Radford, which is part of the Rewards Solutions practice at Aon plc, as its independent compensation consultant to assist the Compensation Committee with evaluating our executive and director compensation programs and make recommendations for our 2021 compensation program to ensure that our programs remain competitive in attracting and retaining talented executives, directors and employees. In general, as part of its review in advance of our 2021 calendar year, Radford provided the Compensation Committee with the following services:

•reviewed and assisted the Compensation Committee with further developing its executive pay philosophy;

•prepared an analysis of our compensation practices with respect to base salaries, annual incentive bonus awards and long-term incentive grants against market practices;

•advised on the design and structure of our cash and equity incentive compensation programs;

•reviewed our equity incentive plan utilization;

•updated the Compensation Committee on emerging trends and best practices in the area of executive and Board compensation;

•provided recommendations as to, and assisted with developing our peer group;

•provided compensation data for similarly situated executive officers at companies in our peer group;

•reviewed and provided an analysis of the compensation arrangements for all of our named executive officers, including the design and structure of our annual incentive bonus plan and equity-based incentive compensation program; and

•reviewed and provided recommendations on the compensation program for our non-employee directors.

35

In the fall of 2021, Radford again performed a similar set of services for use by our Compensation Committee in making its 2022 compensation decisions.

The Compensation Committee has the authority to hire and terminate its compensation consultants. We pay the cost for the consultants’ services. The compensation consultants attend meetings of the Compensation Committee at the request of the Compensation Committee. The Chairman of the Compensation Committee also communicates separately with the compensation consultants at his discretion. If and as requested by the Compensation Committee, the compensation consultants gather information from management necessary to perform their duties to the Compensation Committee. In addition, as described above, members of our legal department also meet separately with the compensation consultants to convey information on proposals that management may make to the Compensation Committee. Radford has not provided any other services to us related to executive compensation or non-executive director compensation.

The Compensation Committee regularly reviews the performance and independence of its compensation consultant and of each individual employee of the consulting firm who directly provides services to us. The Compensation Committee annually considers whether the compensation consultant should continue to serve as its independent advisor. The Compensation Committee requested information from the compensation consultant about potential conflicts of interest, and in particular, considered the fact that Radford provided no other executive compensation services to us, that the individual representatives of Radford who work directly with the Compensation Committee have no other business or personal relationships with the Board, management or our Company, Radford’s own policies on ethics, stock ownership and conflicts of interest, and that the total revenue Radford received from us in 2021 did not exceed 0.5% of Radford’s gross revenues. As a result, the Compensation Committee concluded that there was no conflict of interest with respect to Radford providing services to the Compensation Committee.

Use of Peer Data

In the fall of 2020, the Compensation Committee engaged Radford to review and provide recommendations for updating our peer group in preparation for compensation decisions made for 2021. Based on Radford’s recommendations, our 2020 peer group used for 2021 compensation decisions included 16 public companies in the telecommunications and aerospace/defense industries with revenues or market capitalizations generally comparable to ours. This updated peer group reflects the removal of five companies from our previous peer group that either had been acquired or no longer had comparable revenues or market capitalizations, and the addition of four new companies that met the appropriate selection criteria for inclusion. In addition, Radford also utilized data taken from the Radford Global Technology Survey with respect to public companies with a comparable business profile in evaluating our compensation philosophies and programs. Our 2020 peer group used for 2021 compensation decisions consisted of the following companies:

2020 Peer Group Companies Used for 2021 Compensation Decisions

AeroVironment	GCI Liberty	Shenandoah Telecommunications
ATN International	Kratos Defense & Security	Tenable
Axon Enterprise	ManTech	ViaSat
Cogent Communications	Maxar Technologies	Vonage
Commvault Systems	Mercury Systems
EchoStar	ORBCOMM

36

In the fall of 2021, Radford again reviewed and updated its recommendations for our peer group. Based on Radford's recommendations, our revised 2021 peer group used for 2022 compensation decisions includes 18 public companies in the telecommunications, aerospace/defense and software services industries with revenues, market capitalizations and employee populations generally comparable to ours. The revised group reflects the removal of two companies from the prior peer group that either had been acquired or no longer had comparable revenues or market capitalizations, and the addition of four companies that met the appropriate selection criteria for inclusion. The selected companies were:

2021 Peer Group Companies Used for 2022 Compensation Decisions

8x8	Commvault Systems	Mercury Systems
AeroVironment	EchoStar	ORBCOMM
Axon Enterprise	Hexcel	Shenandoah Telecommunications, Inc.
Bandwidth	Kratos Defense & Security	Tenable
Calix	ManTech	ViaSat
Cogent Communications	Maxar Technologies	Vonage

Our Compensation Committee does not make decisions solely based on peer data, but refers to peer data to help ensure that target compensation amounts selected by the Compensation Committee do not materially deviate from market practices and that target amounts provide fair compensation given individual and Company performance. In particular, the Compensation Committee requested data from Radford at the 25th percentile, median and 75th percentile of the peer group for base salary, target annual incentive bonus, actual annual incentive bonus, aggregate equity award value, total target compensation and total actual compensation. However, individual compensation decisions may deviate from peer data, as our Compensation Committee discussed the peer data and made the 2021 compensation decisions in the context of:

•the differences in our executives’ responsibilities and tenure, as compared to the executives in our peer group, as title is not always determinative of the comparability of role from one organization to another;

•the experiences, knowledge and business judgment of each executive;

•corporate and individual performance, which includes setting target compensation opportunities after taking into account, in a subjective fashion, performance in the prior year, as well as the anticipated demands on the executive in the coming year;

•the desire to maintain target pay opportunities and allocations between cash and equity at levels that were consistent with historical pay levels for each of our executives, given the responses to our past say-on-pay proposals;

•the Compensation Committee's desire to maintain the base salaries of our named executive officers at their fiscal 2020 levels, in order to control costs in light of the uncertainty presented by the COVID-19 pandemic; and

•internal pay equity, which we view from the perspective that (1) the target total compensation of our executive officers, other than our chief executive officer, should be within two separate relatively narrow ranges, and (2) the target total compensation of our chief executive officer should be meaningfully higher than that of our other officers, in each case, given the relative weight of their responsibilities and ability to impact our corporate performance.

37

Reasons for Providing, and Manner of Structuring, the Key Compensation Elements in 2021

We strive to recognize our executive team's efforts by compensating our named executive officers for the increased demands associated with our business through three elements that are designed to reward performance in a simple and straightforward manner: (i) base salaries; (ii) annual, performance-based bonuses; and (iii) long-term equity awards. The purpose and key characteristics of each of these elements paid and awarded in 2021 are summarized below.

Element	Purpose	Key Characteristics
Base Salary	Provides a fixed level of compensation for performing the essential day-to-day elements of the job; gives executives a degree of certainty in light of having a majority of their compensation at risk.	Fixed compensation that is reviewed annually and adjusted if and when appropriate; reflects each executive officer’s performance, experience, skills, level of responsibility, and the breadth, scope and complexity of the position as well as the competitive marketplace for executive talent specific to our industry.
Annual Incentive Bonus Program	Motivates executive officers to achieve corporate and individual business goals, which we believe increase stockholder value, while providing flexibility to respond to opportunities and changing market conditions.	Annual incentive award based on corporate and individual performance compared to pre-established goals, with a portion of the target award paid in the form of RSUs subject to vesting based on attainment of performance goals and continued service through vesting date. Corporate goals focus on overarching objectives for the organization, while individual objectives represent key performance expectations at the departmental or individual level. Corporate goals were derived from our Board-approved operating plan for 2021 and aligned with our business strategy and weighted by relative importance in 2021 so that achievement can be objectively measured.
Long-Term Equity Incentives (RSUs)	Motivates executive officers to achieve our business objectives by tying compensation to the performance of our common stock over the long term and, with respect to performance-based RSUs, the achievement of key performance goals selected by our Compensation Committee; motivates our executive officers to remain with our Company by mitigating swings in incentive values during periods when market volatility weighs on our stock price.	RSU awards vesting based upon achievement of specified corporate goals measured over a two-year period and further subject to additional time-based vesting, as well as RSUs vesting over four years based on continued service; the ultimate value realized varies with the price of our common stock. In determining the aggregate size of equity grants in any given year, the Compensation Committee considers the factors described above under “Base Salaries” as well as data from our peer group and performance of the individual executive.
Other Compensation	Provides benefits that promote employee health and welfare, which assists in attracting and retaining our executive officers.	Indirect compensation element consisting of programs such as medical, vision, dental, life and accidental death and disability insurance, as well as a 401(k) plan with a Company matching contribution and other plans and programs made available to eligible employees, such as financial planning.

2021 Base Salary

In March 2021, the Compensation Committee reviewed the base salaries for our executive officers. In order to control costs in light of the uncertainty presented by the COVID-19 pandemic, the Compensation Committee determined to maintain the base salaries of our named executive officers at their fiscal 2020 levels. The 2021 base salaries for our named executive officers, therefore, were as follows:

Name	2021 Base Salary(1)
Matthew J. Desch	$	952,460
Thomas J. Fitzpatrick	$	571,475
Suzanne E. McBride	$	421,070
Bryan J. Hartin	$	375,032
Scott T. Scheimreif	$	364,315
Thomas D. Hickey	$	380,061

(1)    Based on a 260-workday year. Actual salary paid may be slightly higher based on number of actual workdays in year.

2021 Bonuses

2021 Bonus Plan. In February 2021, the Compensation Committee approved our 2021 executive performance bonus plan, or our 2021 bonus plan, which operated under the terms of our 2015 Plan. Our 2015 Plan, which was most recently approved by our Board and our stockholders in 2019, allows for the granting of performance-based compensation opportunities as amounts paid contingent upon the achievement of pre-established stockholder-approved performance goals. The Compensation Committee had the discretion to reduce the amount of any bonus award payable to any participant in the 2021 bonus plan.

Target Bonus Levels. In March 2021, the Compensation Committee approved a target incentive bonus award for each executive, defined a minimum bonus as zero and capped the maximum bonus award at 195% of the target level in the event that pre-established stretch performance goals were achieved. Each individual’s target bonus percentage was unchanged from 2020, consistent with our philosophy that a significant portion of each executive’s total target compensation should be performance-based, and reflected the Compensation Committee’s review of internal pay equity. The Compensation Committee also considered the recommendation of our chief executive officer that target levels for the other officers not change from 2020 levels and concluded that there were no extraordinary factors creating a need to modify the 2020 target bonus levels. The respective target amounts for 2021 for our named executive officers were:

Name	2021 Target  Bonus(1)		Percentage of  2021 Base Salary
Matthew J. Desch	$	857,214	90%
Thomas J. Fitzpatrick	$	428,606	75%
Suzanne E. McBride	$	252,642	60%
Bryan J. Hartin	$	225,019	60%
Scott T. Scheimreif	$	218,589	60%
Thomas D. Hickey	$	228,037	60%

(1)    Assumes salary based on a 260-workday year. Actual target bonus may be slightly higher if base salary is higher depending on number of actual workdays in year.

2021 Bonus Plan Structure and Metrics. As adopted, the 2021 bonus plan contained both metrics to judge performance and methodology for calculation of actual bonuses paid, as follows:

•The dollar value of the actual bonus award for each executive under the 2021 bonus plan was to be calculated by multiplying the executive’s target bonus amount (as adjusted based on actual salary earned) by a corporate performance factor determined by the Compensation Committee, which could range from 0% to 195% based on the level of achievement of the corporate performance goals discussed below.

•The corporate performance factor would equal the sum of the level of achievement of one financial, several strategic and several operational performance goals.

39

•The resulting amount could then be reduced but not increased by the Compensation Committee based on an individual performance factor ranging from 0% to 100% (the final number being the “Actual Bonus Award”).

•Sixty percent of each executive’s target bonus award was granted in the form of RSUs, or the Bonus RSUs, that were eligible to vest upon the Compensation Committee certifying achievement of the performance goals in the first quarter of 2022.

•To the extent the Actual Bonus Award calculated according to the methodology above would exceed the dollar value of the Bonus RSUs on the date of grant, the excess amount would be paid to the executive in cash.

•To the extent the Actual Bonus Award calculated according to the methodology above would be less than the dollar value of the Bonus RSUs on the date of grant, the excess Bonus RSUs that did not vest would be forfeited by the executive.

•To be eligible for a bonus under the 2021 bonus plan, the executive was required to remain employed by us through the date upon which the Bonus RSUs actually vested in the first quarter of 2022, after the Compensation Committee certified achievement of the performance goals, and the date any amount of the Actual Bonus Award that exceeded the dollar value of the Bonus RSUs was to be paid in cash, except as otherwise provided in an executive’s employment agreement in connection with a termination of employment. As described in further detail under “Thomas D. Hickey Separation Benefits” below, and consistent with the terms of his employment agreement, Mr. Hickey remained eligible for a bonus under the 2021 bonus plan following his termination of employment with the Company on December 31, 2021.

•For 2021, the corporate performance factor was the sum of the achievement levels of the following corporate goals, as further described below:

Performance Goal	Target  Performance Weighting	Potential Excess Achievement	Actual Achievement
Operational EBITDA(1)	65%	0% to 65% on a sliding scale	100.6%
Strategic Goals	20%	0% to 15% on a sliding scale	12.6%
Network and Quality Metrics	15%	0% to 15% on a sliding scale	30.0%
Total of Target Weighting	100%	—
Total of Excess Potential Achievement Weightings	—	95%
Maximum Possible Award		195%
Actual Performance(2)			143.2%

(1)    “Operational EBITDA” or “OEBITDA” is defined to equal the OEBITDA we report as full year performance. OEBITDA represents earnings before interest, income taxes, depreciation and amortization, and share-based compensation expenses. We consider the loss on early extinguishment of debt to be financing-related costs associated with interest expense or amortization of financing fees, which by definition are excluded from OEBITDA.

(2)     Our 2021 bonus plan specifies that payouts are rounded to the closest payout percentage integer.

•Operational EBITDA:

◦An Operational EBITDA target of $370.0 million, weighted at 65%, with a potential stretch payout of up to an additional 65% for performance at or above 104.1% of the target and a lesser payout down to 0% credit for performance below 95.9% of the target, with achievement between the minimum and maximum levels being interpolated linearly.

•Strategic Goals:

◦Commercial Broadband Subscription Growth – a target goal of adding a specified number of net commercial broadband subscribers during 2021 in support of future revenue growth, weighted at 5%, with a potential stretch payout of up to an additional 5% for performance at or above 211% of the target and no payout for performance below the target, with achievement between the target and maximum levels being interpolated linearly;

40

◦U.S. Government Engineering Margin – a target goal of achieving total engineering and support services revenue with a specified margin, weighted at 5%, with a potential stretch payout of up to an additional 5% for performance between 110% and 119% of the target and no payout for performance below the target, with achievement between 110% and 119% of the target level being interpolated linearly with respect to the potential stretch payout;

◦Product Development – a 5% target weighting for completing two product development milestones with respect to our messaging services by December 31, 2021, within budget, and in satisfaction of all technical criteria; and

◦Product Shipment – a target goal of shipping a specified number of Iridium Certus midband units during 2021 in support of future midband service revenue growth, weighted at 5%, with a potential stretch payout of up to an additional 5% for performance at or above 131% of the target and no payout for performance below the target, with achievement between the target and maximum levels being interpolated linearly.

•Network and Quality Metrics:

◦High-Quality Iridium Certus Customer Experience – a 5% target weighting for optimizing Iridium Certus performance, with a potential stretch payout of up to an additional 5%, in each case based on achievement of specified customer satisfaction metrics, including the percentage of time our users' bandwidth requests are met;

◦Gateway Service Availability – a 5% target weighting for having fewer than a specified number of gateway service outage minutes in 2021, with a potential stretch payout of up to an additional 5% for having fewer than a specified number of significant core service outages in 2021; and

◦GMDSS Service Availability – a 5% target weighting for meeting the International Maritime Organization's annual network availability requirement in 2021, with a potential stretch payout of up to an additional 5% for having no GMDSS outage lasting more than a specified period of time in 2021.

At the time the Compensation Committee set our goals for 2021, the Compensation Committee believed that each of the 2021 bonus plan goals was achievable at the target level, but only with significant effort. Our Operational EBITDA target for 2021 reflected an approximately 4% increase over our actual results for 2020. Other targets represented the achievement of significant new product milestones and increased sales levels, as well as continued improvement across several operational areas.

Performance and Bonus Payouts under 2021 Bonus Plan. In 2021, our performance against our corporate goals resulted in an aggregate corporate performance factor under our 2021 bonus plan of 143%, calculated as follows:

•We achieved Operational EBITDA of $378.2 million, or 102.2% of our Operational EBITDA target, yielding 100.6% credit under the 2021 bonus plan;

•Under our strategic goals, we supported our future revenue growth by adding net commercial broadband subscribers in excess of our target level in 2021 (yielding 7.6% credit), and we further cemented our strategic U.S. government relationship by achieving the specified total engineering and support services revenue margin (yielding 5% credit), resulting in a combined 12.6% credit under our strategic goals for 2021; and

•Under our network and quality metrics, we achieved the target and stretch goals under our Iridium Certus customer experience metric (yielding 10% credit), the target and stretch goals under our gateway service availability metric (yielding 10% credit), and the target and stretch goals under our GMDSS service availability metric (yielding 10% credit), resulting in a combined 30% credit under our network and quality metrics for 2021.

In the first quarter of 2022, our chief executive officer shared his evaluations of the individual performance of each of our other named executive officers with the Compensation Committee. Based upon our chief executive officer’s recommendations, and based upon a review of our chief executive officer’s performance, the Compensation Committee concluded that each executive was performing at or above expected individual performance levels, and therefore the Compensation Committee did not reduce any executive’s bonus based on his or her individual performance. As a result, the Bonus RSUs vested in full, and executives received the remainder of their earned bonuses in cash, as follows:

Name	Actual Target Bonus Level ($)(1)	60% of Target Bonus Payable in RSUs ($)(2)	RSUs  Granted with Fair Value(3) Equal to 60% of Target Bonus (#)	Corporate Performance (%)	Individual Performance (%)	RSUs Vested (#)	Cash Bonus Paid ($)(4)	Actual Bonus Earned ($)(5)
Matthew J. Desch	860,511	514,320	12,272	143	100	12,272	716,211	1,230,531
Thomas J. Fitzpatrick	430,255	257,160	6,136	143	100	6,136	358,105	615,265
Suzanne E. McBride	253,614	151,547	3,616	143	100	3,616	211,121	362,668
Bryan J. Hartin	225,885	134,992	3,221	143	100	3,221	188,024	323,016
Scott T. Scheimreif	219,430	131,136	3,129	143	100	3,129	182,649	313,785
Thomas D. Hickey	228,914	136,794	3,264	143	100	3,264	190,553	327,347

(1)Derived from actual salary paid as reflected in our 2021 Summary Compensation Table.

(2)Derived from base salary using a 260-workday year as reflected in the 2021 Base Salary table above.

(3)Based on the closing price of our common stock of $41.91 per share on March 1, 2021, the date of grant of the Bonus RSUs, with amount rounded down to the nearest whole share.

(4)Reflects 143% of actual target bonus less the grant date value of the vested Bonus RSUs.

(5)Equal to cash bonus paid plus the grant date value of the vested Bonus RSUs.

Because each named executive officer earned an actual bonus equal to 143% of the executive’s target bonus for the 2021 performance year, all of the Bonus RSUs granted to each named executive officer in 2021 pursuant to the 2021 bonus plan vested in March 2022, and the shares of common stock underlying the Bonus RSUs were issued to the named executive officers, net of shares withheld for payment of required withholding taxes. The remaining 83% of each named executive officer’s bonus was paid in cash in March 2022 to each named executive officer other than Mr. Hickey. Pursuant to his transition agreement with the Company, the remaining 83% of Mr. Hickey's actual bonus will be paid in cash in equal installments on the Company's normal payroll schedule from March 2022 through December 2022.

2022 Bonus Plan Structure. In February 2022, our Compensation Committee adopted a similar bonus plan, or the 2022 bonus plan, for our executives, pursuant to which the first 60% of each executive’s target annual performance bonus for the 2022 calendar year, if earned based upon achievement of the performance goals approved by the Compensation Committee, will be paid in the form of RSUs instead of cash. Accordingly, on March 1, 2022, each of our named executive officers (other than Mr. Hickey) was granted RSUs under our 2015 Plan, which will vest, if at all, based upon our corporate performance and each executive’s individual performance as set forth under our 2022 bonus plan as certified by our Compensation Committee in 2023, subject to each executive’s continued service with us through the vesting date in March 2023. The portion of each executive’s annual performance bonus that exceeds 60% of target, if any, up to the maximum award of 185% of the target level, will be paid in cash in March 2023.

Long-Term Equity-Based Incentive Compensation

In 2021, as in past years, we awarded equity in the form of RSUs, which vest based on continued service over a four-year period, as well as equity under our performance share program, which provides for the grant of performance-based RSUs. The Compensation Committee established our performance share program in 2012 to (1) focus key employees on achieving specific performance targets, (2) reinforce a team-oriented approach, (3) provide significant award potential for achieving outstanding performance, and (4) enhance our ability to attract and retain highly talented individuals. Under this program, the Compensation Committee grants awards to designated key employees, with each award representing a specified maximum number of shares of common stock that may ultimately be earned under each award. The maximum award is calculated by reference to the target award dollar value, which is then converted into a number of shares underlying the RSUs based on the closing price of our common stock on the date of grant. The number of shares ultimately earned and vested under the award is determined based on

42

achievement of performance goals over a two-year performance period, and is subject to additional time-based vesting thereafter. The Compensation Committee sets the performance goals to be achievable, but only with significant effort, as illustrated by the lack of vesting and partial vesting of prior year performance-based RSUs, as detailed under the section titled “Executive Summary – Pay for Performance” above.

The Compensation Committee determined an aggregate target award size for each executive in 2021 based principally on (1) the peer data provided by Radford, which showed measurably higher peer company grant levels than in prior years, (2) our internal equity budget for grants for 2021, (3) internal pay equity and individual performance, (4) the recommendations of our chief executive officer and (5) retention of individual executives. In determining these aggregate target award sizes, the Compensation Committee also took into consideration the significant achievements of the executive team during 2020 and early 2021 in the face of an unprecedented business environment, which included, among other things, (1) generating record total revenue of $583.4 million, a 4% year-over-year increase, (2) ending the year with 1,476,000 worldwide subscribers, a 14% year-over-year increase, which was driven by growth in commercial IoT and government business, (3) the February 2021 launch of the first share repurchase program in the Company's history, which authorized the repurchase of up to $300.0 million of our common stock through December 31, 2022, and (4) completing a repricing of our term loan in January 2021 that resulted in a 1.0% reduction in the borrowing rate, which was expected to produce aggregate annual interest expense savings of approximately $16.0 million per year.

Based on the recommendations of Radford, the Compensation Committee allocated approximately 50% of the target dollar value of each award in the form of RSUs subject to a four-year vesting schedule, and approximately 50% in the form of performance-based RSUs. The Compensation Committee determined that this mix of time-based and performance-based RSUs for 2021 was appropriate to promote our retention, motivation and stockholder alignment goals.

RSU Grants. As described above, the Compensation Committee approved the March 1, 2021 grant of RSUs to each of our executive officers that would be subject to vesting based on continued service over four years, with one-quarter vesting on March 1, 2022, and the remainder vesting thereafter in twelve equal quarterly installments. The number of RSUs granted was equal to the target grant value divided by the closing price of our common stock on March 1, 2021, the date of grant of the RSUs, rounded down to the nearest whole share.

The service-based RSUs granted to our named executive officers in 2021 were as follows:

Name	Target Value ($)	Number of Shares Underlying RSU Grant
Matthew J. Desch	1,600,000	38,177
Thomas J. Fitzpatrick	875,000	20,878
Suzanne E. McBride	875,000	20,878
Bryan J. Hartin	450,000	10,737
Scott T. Scheimreif	450,000	10,737
Thomas D. Hickey	350,000	8,351

Performance-Based RSU Grants. In addition, as described above, the Compensation Committee approved target performance-based share awards for our executive officers. The number of RSUs subject to the target performance-based share awards was equal to the target grant value divided by the closing price of our common stock on March 1, 2021, the date of grant of the performance-based share awards, rounded down to the nearest whole share.

43

The performance-based RSUs granted to our named executive officers in 2021 were as follows:

Name	Target Value ($)	Number of Shares Underlying RSU Grant
Matthew J. Desch	1,600,000	38,177
Thomas J. Fitzpatrick	875,000	20,878
Suzanne E. McBride	875,000	20,878
Bryan J. Hartin	450,000	10,737
Scott T. Scheimreif	450,000	10,737
Thomas D. Hickey	350,000	8,351

The actual awards to be earned by each executive will be determined based on the achievement of a specified average percentage increase in our service revenue calculated in accordance with generally accepted accounting principles in the United States, or GAAP service revenue, for 2021 and 2022 (i.e., the average of (i) the percentage increase in GAAP service revenue from 2020 to 2021 and (ii) the percentage increase in GAAP service revenue from 2021 to 2022), as follows:

Awards Earned by Executives
Average Increase in GAAP Service Revenue (%)	Target Shares to Vest (%)
< 2%	0%
2%	50%
2.85%	100%
4%	150%

Achievement between the performance levels in the table above will be interpolated linearly. The Compensation Committee approved these performance levels, which are lower than the performance levels established for the performance-based RSUs granted in 2020, after considering challenges to the Company's operations in 2021, particularly continued uncertainty associated with the COVID-19 pandemic, as well as limited increases in revenues resulting from contractually fixed rates in two of our key contracts that provided more significant increases in prior years. Regardless of the GAAP service revenue achievement, however, the actual awards will be reduced to zero if we fail to achieve an average OEBITDA margin for each of 2021 and 2022, defined as OEBITDA expressed as a percentage of GAAP revenue, of at least 57%.

Once the level of performance described above has been determined, the actual awards earned will also be subject to additional time-based vesting, with 50% of the earned shares vesting when the Compensation Committee determines our level of achievement of the performance goals, which will occur in the first quarter of 2023, and the remaining 50% vesting one year thereafter in the first quarter of 2024, subject in each case to continuous employment of the participant with us or our subsidiaries through such dates. If a change in control were to occur before the date the Compensation Committee determines our level of achievement of the performance goals, then, effective as of immediately prior to the change in control, each executive officer’s actual award would vest at the target level, and the actual awards would be subject to the same time-based vesting schedule, with the first vesting date being March 1, 2023 and the second vesting date being March 1, 2024.

Other Executive Compensation Matters

Equity Compensation Policies

As a general matter, the Compensation Committee makes compensatory equity grants no more frequently than on January 1, March 1, June 1 and October 1 of each year. As necessary to meet business needs, the Compensation Committee or the Board may grant equity awards outside of these regularly scheduled dates. Our Compensation Committee followed this schedule in 2021 and made the March 1, 2021 equity grants described above to each of our named executive officers.

Policy Regarding Hedging, Pledging and Short Sales In Our Common Stock

In addition to our stock ownership and holding guidelines described below, our executive officers and directors are subject to our insider trading policy, which prohibits all employees and directors from engaging in short sales, transactions in put or call options, hedging transactions, margin accounts, pledging or other inherently speculative transactions with respect to our stock. We maintain this policy because such transactions, which might be considered short-term bets on the movements of our stock, could create the appearance that the person is trading on inside information. In addition, transactions in options may also focus the person’s attention on short-term performance at the expense of our long-term objectives. We believe this policy serves to further align the interests of our employees, executives and directors with our stockholders’ interests.

Stock Ownership and Holding Guidelines

In 2012, our Compensation Committee adopted stock ownership guidelines for our directors and executives at the level of vice president and above. The Compensation Committee also determined that stock ownership guidelines help align the interests of our executives with those of our stockholders and may act as a risk mitigation device. Each individual subject to the stock ownership guidelines was in compliance with the guidelines as of March 15, 2022.

The stock ownership guidelines are based on a multiple of annual base salary or annual cash retainer, as follows:

Position	Ownership Guideline
Non-Employee Director	4 times annual cash retainer (retainer is currently $50,000)
Chief Executive Officer	4 times annual base salary
Executive Vice Presidents	2 times annual base salary
Senior Vice Presidents	1 times annual base salary
Vice Presidents	1/2 of annual base salary

For purposes of these guidelines, “ownership” includes: (1) shares directly (not just beneficially) owned; (2) shares directly (not just beneficially) owned jointly by the individual and his or her spouse; (3) shares held in trust or other estate planning vehicle (e.g., family limited partnership) for the benefit of the individual and/or his or her family members; (4) shares equal to the number of vested deferred stock units credited to the individual under a deferred compensation arrangement; and (5) shares credited to the individual’s 401(k) plan account.

There is no specific time period within which the individual must attain the applicable stock ownership targets under the guidelines. Rather, until an individual comes into compliance with the guidelines, he or she is required to retain 50% percent of Net Profit Shares from each stock award on exercise, vesting or earn-out. “Net Profit Shares” means: (1) shares received on the vesting or issuance (as applicable) of full value stock awards (e.g., restricted stock, RSUs, performance shares) granted after these guidelines were adopted, net of the number of shares withheld or sold at vesting or issuance to cover taxes; and (2) shares received on the exercise of stock options granted after February 1, 2012, net of the number of shares tendered to us or sold at exercise to cover the exercise price and taxes related to exercise.

Change in Control and Severance Benefits

Under the terms of the employment agreements with each of our executive officers, either we or the executive may terminate the executive’s employment at any time. Each of our named executive officers is eligible, under the terms of his or her respective employment agreement, to receive, in exchange for a release of claims, severance benefits upon the termination of employment either by us without cause or by him or her for good reason, with additional severance benefits provided in the event the termination is in connection with a change in control. The terms and conditions of severance provisions are discussed more fully below under the heading “– Potential Payments upon Termination or Change in Control.” We do not provide any excise tax gross-ups on change-in-control benefits.

These agreements reflect the negotiations with our named executive officers at the time we entered into the agreements, as well as our desire to have a consistent set of benefits across the executive team. Our Compensation Committee considers these severance benefits critical to attracting and retaining high-caliber executives. Additionally, our Compensation Committee believes that additional change-in-control severance benefits minimize the distractions to an executive in connection with a corporate transaction and reduce the risk that an executive officer departs before a transaction is completed. We believe that our existing arrangements allow our executive officers to focus on continuing normal business operations and, in the case of

45

change-in-control benefits, on the success of a potential business combination, rather than worry about how business decisions that may be in our best interest will impact their own financial security. These existing arrangements help ensure stability among our executive officer ranks and are designed to enable our executives to maintain a balanced perspective in making overall business decisions during periods of uncertainty.

Thomas D. Hickey Separation Benefits

In connection with Mr. Hickey's separation of employment on December 31, 2021, we entered into a transition agreement and a consulting agreement with Mr. Hickey, each dated December 31, 2021. Pursuant to the transition agreement, he provided a release of claims in exchange for the following severance payments and benefits to which he was entitled: (i) a cash payment equal to one times his then-current base salary, payable in equal installments on our normal payroll schedule over the 12-month period ending December 31, 2022; (ii) a cash payment equal to 12 times his monthly COBRA premium, payable within 60 days following December 31, 2021; and (iii) a cash payment equal to the cash portion of the 2021 bonus amount he would have earned had he remained employed by us through the payment date for such bonus, payable in equal installments on our normal payroll schedule from March 2022 through December 2022.

Pursuant to the consulting agreement, Mr. Hickey has agreed to provide consulting services to us through March 31, 2023 in exchange for the following payments and benefits: (i) a consulting fee of $105,000, which was paid on January 14, 2022; (ii) continued vesting of certain of Mr. Hickey's outstanding and unvested equity awards, including the service-based RSUs and performance-based RSUs granted to him in 2021, in accordance with their terms while he continues to provide services to us under the consulting agreement; and (iii) extension of the exercise period for certain of Mr. Hickey's outstanding stock options in accordance with their terms while he continues to provide services to us under the consulting agreement.

Employee Benefits

We provide broad-based medical insurance, dental insurance, vision coverage, life insurance, and accidental death and dismemberment insurance benefits to our employees, including our named executive officers. We also provide our employees, including our named executive officers, with the opportunity to participate in our 401(k) plan. We match eligible employee contributions dollar for dollar up to 5% of an employee’s salary, with a maximum match per employee of $14,500 in 2021. We also provide our executive officers, other than our chief executive officer, and our vice-president level employees with financial planning services. We believe these insurance, financial planning and retirement savings benefits are consistent with practices of similarly sized companies and help to recruit and retain key talent at a minimal cost to us.

In addition, beginning in 2022, we now offer a Company-wide program that provides accelerated vesting of RSU awards held by eligible participants who retire on or after the six-month anniversary (or a later anniversary, in the case of our executive officers, as described below) of the RSU award's grant date. To be an eligible participant, at the time of retirement, the employee must have attained (1) a minimum age of 55, (2) a minimum of 10 years of continuous service with us or one of our subsidiaries, and (3) a minimum of 70 combined years of age and continuous service with us or one of our subsidiaries. With respect to RSU awards granted in 2022, our chief executive officer must retire on or after the two-year anniversary of the RSU award's grant date, and our other executive officers must retire on or after the one-year anniversary of the RSU award's grant date, in order to be eligible for this retirement benefit. With respect to RSU awards to be granted in 2023, all of our executive officers must retire on or after the one-year anniversary of the RSU award's grant date in order to be eligible for this retirement benefit. With respect to RSU awards to be granted after 2023, all of our executive officers must retire on or after the six-month anniversary of the RSU award's grant date in order to be eligible for this retirement benefit.

Our executive officers generally do not receive any supplemental retirement benefits or other perquisites, except for life insurance provided to our chief executive officer. In considering potential perquisites, the Compensation Committee compares the cost to the value of providing these benefits.

We have agreed to purchase and maintain a term life insurance policy in the face amount of $400,000 for Mr. Desch. This benefit is provided as a result of negotiations with Mr. Desch when his employment commenced with our subsidiary Iridium Holdings in 2006. With respect to the term life insurance policy, the Compensation Committee decided that rather than paying Mr. Desch this amount as severance upon death out of our general assets, it was more cost-effective to provide for these payments through insurance.

This limited perquisite helped us to recruit Mr. Desch, and now it helps us to retain his services, at what the Compensation Committee believes is a minimal cost to us.

Deductibility of Executive Compensation Under Code Section 162(m)

Under Section 162(m) of the Code, compensation paid to any publicly held corporation’s “covered employees” that exceeds $1 million per taxable year for any covered employee is generally non-deductible.

Prior to the enactment of the Tax Cuts and Jobs Act, Section 162(m) provided a performance-based compensation exception, pursuant to which the deduction limit under Section 162(m) did not apply to any compensation that qualified as “performance-based compensation” under Section 162(m). Pursuant to the Tax Cuts and Jobs Act, the performance-based compensation exception under Section 162(m) was repealed with respect to taxable years beginning after December 31, 2017, except that certain transition relief is provided for compensation paid pursuant to a written binding contract which was in effect on November 2, 2017 and which is not modified in any material respect on or after such date.

Compensation paid to each of our “covered employees” in excess of $1 million per taxable year generally will not be deductible unless it qualifies for the performance-based compensation exception under Section 162(m) pursuant to the transition relief described above. Because of certain ambiguities and uncertainties as to the application and interpretation of Section 162(m), as well as other factors beyond the control of the Compensation Committee, no assurance can be given that any compensation paid will be eligible for such transition relief and be deductible by us in the future. Although the Compensation Committee will continue to consider tax implications as one factor in determining executive compensation, the Compensation Committee also looks at other factors in making its decisions and retains the flexibility to provide compensation for our named executive officers in a manner consistent with the goals of our executive compensation program and the best interests of the Company and its stockholders, which may include providing for compensation that is not deductible due to the deduction limit under Section 162(m). The Compensation Committee also retains the flexibility to modify compensation that was initially intended to be exempt from the deduction limit under Section 162(m) if it determines that such modifications are consistent with our business needs.

Accounting Considerations

The accounting impact of our executive compensation program is one of many factors that the Compensation Committee considers in determining the size and structure of that program.

Compensation Recovery Policy

In December 2019, our Board adopted a compensation recovery policy. In the event we are required to restate our financial results due to material noncompliance with any financial requirement and the misconduct of an executive officer covered by the policy contributed to such noncompliance, we may recover the amount of any incentive compensation, including any cash or equity compensation granted, earned or vested based in whole or in part on the attainment of a financial performance goal or metric (such as under our 2021 bonus plan and our performance share program and any other program or plan approved after the adoption of the policy), that was paid to him or her during the three-year period preceding the date of the restatement and attributable to the erroneously reported results. In addition, if any covered executive officer sells stock acquired pursuant to an equity award granted after the policy's adoption and the sale occurs between the time our financial results are reported and the time those results are required to be restated, we may recover the excess of the actual sale proceeds over the proceeds the Board determines the executive officer would have received from the sale if the restatement had occurred prior to the sale. The executive officers covered by the policy include our current or former executive officers who are, or were at the time of the relevant misconduct, designated by the Board as an officer for purposes of Section 16 of the Securities Exchange Act of 1934, as amended. The misconduct covered by the policy includes any knowing violation of SEC rules and regulations, breach of fiduciary duty or willful commission of an act of fraud, dishonesty, gross recklessness or gross negligence in the performance of the executive officer's duties, as determined by the Board.

In addition to our compensation recovery policy, amounts paid and awards granted under our 2021 bonus plan, our performance share program, our 2012 Equity Incentive Plan and our 2015 Plan are subject to recoupment in accordance with the Dodd-Frank Wall Street Reform and Consumer Protection Act and any applicable regulations thereunder. Further, as a public company subject to the provisions of Section 304 of the Sarbanes-Oxley Act of 2002, if we are required as a result of misconduct to restate our financial results due to our material noncompliance with any financial reporting requirements under the federal securities laws, our chief executive officer and chief financial officer may be legally required to reimburse us for any bonus or other incentive-based or equity-based compensation they receive.

Risk Analysis of Our Compensation Plans

In early 2022, Radford conducted a risk assessment of our compensation policies in effect for 2021 and delivered a report to the Compensation Committee summarizing the results of their risk assessment. The Compensation Committee has reviewed the report and considered our compensation policies as generally applicable to our employees and believes that our policies do not encourage excessive or unnecessary risk-taking, and that the level of risk that they do encourage is not reasonably likely to have a material adverse effect on us. We design our compensation policies and programs to encourage our employees to remain focused on both our short- and long-term goals. For example, while our annual incentive bonus plans measure performance on an annual basis, our equity awards typically vest over a number of years, which we believe encourages our employees to focus on sustained stock price appreciation, thus limiting the potential value of excessive risk-taking.

(1)The amounts in this column reflect the actual salary earned in the applicable year. Starting in 2020, these may be greater than the annual base salaries when the actual number of days worked exceeds 260.

(2)The amounts in this column reflect the aggregate grant date fair value of RSUs and performance-based RSUs (including Bonus RSUs) granted in the applicable year, computed in accordance with Financial Accounting Standards Board, or FASB, Accounting Standards Codification, or ASC, Topic 718 for stock-based compensation transactions, or Topic 718. Pursuant to SEC rules, the amounts shown exclude the impact of estimated forfeitures related to service-based vesting conditions, and, for performance-based RSUs, the amounts represent the value based on the probable outcome of the performance conditions in accordance with FASB ASC Topic 718. For the performance-based RSUs included in this column, the grant date fair values based on the target level of achievement, which was considered to be the probable outcome, were $2,114,318 for Mr. Desch, $1,132,157 for Mr. Fitzpatrick, $1,026,544 for Ms. McBride, $584,980 for Mr. Hartin, $581,124 for Mr. Scheimreif and $486,785 for Mr. Hickey. Assuming the highest level of achievement of all performance-based RSUs granted in 2021, the grant date values for performance-based RSUs would be $2,914,296 for Mr. Desch, $1,569,655 for Mr. Fitzpatrick, $1,464,042 for Ms. McBride, $809,953 for Mr. Hartin, $806,097 for Mr. Scheimreif and $661,759 for Mr. Hickey. Assumptions used in the calculation of these amounts are included in Note 10 to our consolidated financial statements included in our annual report on Form 10-K for the year ended December 31, 2021. A portion of the performance-based RSUs included in these amounts reflect the equity incentive bonuses earned for a performance period that ended as of the end of the respective year but were paid during the first quarter of the following year.

(6)Ms. McBride's employment commenced on February 11, 2019. Her employment agreement includes a cash bonus of $50,000 payable on each of February 15, 2021, 2020 and 2019, subject to her continued employment with us on each such date, and an initial stock option grant.

(7)Mr. Hickey's employment ended on December 31, 2021. He was not a named executive officer for 2020 or 2019, and as a result his compensation for those years has been omitted pursuant to applicable SEC rules and regulations.

(8)In addition to the amounts described in footnote (5), for Mr. Hickey, the amount includes the following separation benefit amounts as further described under “Compensation Discussion and Analysis - Thomas D. Hickey Separation Benefits” above: (a) $380,061, equal to one times his 2021 base salary, (b) $27,656, equal to 12 times his monthly COBRA premium, and (c) a consulting fee of $105,000.

(1)Performance RSU: Share amounts in this row represent threshold (50% of target), target and maximum (150% of target) payouts for each named executive officer for grants made in 2021 under our 2021 performance-based restricted stock unit award program, as described above under “Compensation Discussion and Analysis—Reasons for Providing, and

49

Manner of Structuring, the Key Compensation Elements in 2021—Long-Term Equity-Based Incentive Compensation—Performance-Based Restricted Stock Unit Grants.”

(2)2021 Bonus Plan: As described above under “Compensation Discussion and Analysis—Reasons for Providing, and Manner of Structuring, the Key Compensation Elements in 2021—2021 Bonuses,” each executive could earn an annual bonus of up to 195% of such executive’s target bonus amount. Achievement of up to 60% of the target bonus is payable by the vesting of the RSUs included in this row under “Estimated Future Payouts under Equity Incentive Plan Awards.” Bonus awards in excess of 60% of target were payable in cash. There is no threshold amount of payout. Target amounts reported in this row under “Estimated Possible Payouts Under Non-Equity Incentive Plan Awards” represent 40% of the executive’s target bonus, which is the amount of cash that could be paid to the executive if the bonus were achieved at 100% of target. Maximum amounts reported in this row under “Estimated Possible Payouts Under Non-Equity Incentive Plan Awards” represent 135% of the executive’s target bonus, which is the maximum possible amount of cash that would be paid to the executive under the annual bonus plan. As described above for 2021, each executive earned 143% of his or her actual earned target bonus amount, as a result of which 100% of the shares reported under the “Target” column vested in March 2022 (representing 60% of target bonus), and the remainder (83% of target bonus) was paid in cash at that time.

(3)Service-Based RSU: Share amounts in this row are subject to vesting based on continued service over four years, with one-quarter of the shares vesting on March 1, 2022, and the remainder vesting thereafter in twelve equal quarterly installments.

(1)All options awarded vest 25% on the first anniversary of their grant date, with the remaining 75% vesting thereafter in 12 equal quarterly installments.

(2)The expiration date of each stock option is ten years from the date of grant.

(3)The market value amount is calculated based on the closing price of our common stock of $41.29 on December 31, 2021.

(4)These shares represent time-based RSUs outstanding at December 31, 2021 which vest 25% on the first anniversary of their grant date, with the remaining 75% vesting thereafter in 12 equal quarterly installments.

(5)These shares represent RSUs granted in March 2019 as performance-based grants, with a performance period through December 31, 2020. In February 2021, the Compensation Committee determined the level of performance achievement, and the awards remained subject to time-based vesting as of December 31, 2021. The share amounts shown in the table vested in full on March 1, 2022, and the shares underlying the RSUs were issued to the named executive officer on that date, net of shares withheld to satisfy tax withholding obligations.

(6)These shares represent RSUs granted in March 2020 as performance-based grants, with a performance period through December 31, 2021. This amount represents 65% of the original grant, which the Compensation Committee determined in February 2022 to be the level of performance achievement, based on actual performance. One-half of the shares reported in the table vested on March 1, 2022, and the vested shares were issued to the named executive officer on that date, net of shares withheld to satisfy tax withholding obligations, and the remainder will vest on March 1, 2023, subject to the executive’s continued service through such date.

(7)These shares represent RSUs granted in March 2021 as performance-based grants, with a performance period through December 31, 2022. The number of shares not yet earned is based on the target amount. Upon the Compensation Committee’s determination of the level of performance achievement, which is expected to occur in the first quarter of 2023, the earned awards, if any, will vest in March 2023 and March 2024, subject to the executive's continued service.

(8)These shares represent RSUs granted in March 2021 under the 2021 bonus plan. The amount reported in the table is equal to 100% of the original grant amount. In February 2022, the Compensation Committee determined that the performance criteria for vesting had been achieved, as a result of which these RSUs vested in full on March 1, 2022, and the shares underlying the RSUs were issued to the named executive officer on that date, net of shares withheld to satisfy tax withholding obligations.

Potential Payments upon Termination or Change in Control

The section below describes the payments that may be made to the named executive officers in connection with a change in control or pursuant to specified termination events, pursuant to the terms of the employment agreements between us and them.

Matthew J. Desch. Mr. Desch’s employment agreement, described above, provides that he may be terminated by us for any reason upon written notice. However, the employment agreement provides for payments to him in the event of the termination of his employment in specified termination situations.

Termination by reason of death or disability. If Mr. Desch’s employment is terminated due to his death or disability (as defined in his employment agreement), he will receive a bonus based on the amount he would have been entitled to receive if he had remained employed by us throughout the applicable fiscal year and until the applicable payment date, but pro-rated for the number of days he was employed during such year.

Termination without cause, for good reason or in connection with a change in control. In the event that we terminate Mr. Desch’s employment without cause, or Mr. Desch terminates his employment for good reason (as these terms are defined in his employment agreement), he will be entitled to receive a sum equal to (i) 18 months of his then-current base salary and (ii) an amount equal to his bonus for the year in which his employment is terminated, based on the actual achievement of the performance goals, pro-rated for the portion of the year that he was employed by us. He also will receive payment of his COBRA premiums (or, if required for us to comply with nondiscrimination rules, a taxable cash payment equal to the amount of his COBRA premiums) until the earlier of (a) 12 months from separation, (b) the expiration of COBRA eligibility or (c) the date he or his dependents become eligible for substantially equivalent health insurance coverage through new employment or self-employment. In the event that such termination occurs within the 12-month period commencing on a change in control (as defined in our 2009 stock incentive plan), then the cash severance amounts described above shall be paid to him in a single lump sum and in addition to such cash severance payment, 100% of his then-outstanding stock options and other equity awards will become vested and exercisable, as applicable, pursuant to the terms of the applicable equity award agreements.

These severance payments and benefits are subject to Mr. Desch executing a release of claims in our favor.

Thomas J. Fitzpatrick. Mr. Fitzpatrick’s employment agreement, described above, provides that he may be terminated by us for any reason upon written notice. However, the employment agreement provides for payments to him in the event of the termination of his employment in specified termination situations.

Termination without cause, for good reason or in connection with a change in control. In the event that we terminate Mr. Fitzpatrick’s employment without cause, or Mr. Fitzpatrick terminates his employment for good reason (as these terms are defined in his employment agreement), he will be entitled to receive a sum equal to (i) one times his then-current base salary and (ii) one times his then-current target bonus, such sum payable in equal installments over a period of 12 months. He will also receive payment of his COBRA premiums (or, if required for us to comply with nondiscrimination rules, a taxable cash payment equal to the amount of his COBRA premiums) until the earlier of (a) 12 months from separation, (b) the expiration of COBRA eligibility or (c) the date he or his dependents become eligible for substantially equivalent health insurance coverage through new employment or self-employment. In the event that such termination occurs within the 12-month period commencing on a change in control (as defined in our 2009 stock incentive plan), then the cash severance amounts described above shall be paid to him in a single lump sum, and in addition to such cash severance payment, 100% of his then-outstanding stock options and other equity awards will become vested and exercisable, as applicable, pursuant to the terms of the applicable equity award agreements.

These severance payments and benefits are subject to Mr. Fitzpatrick executing a release of claims in our favor.

Suzanne E. McBride. Ms. McBride’s employment agreement, described above, provides that she may be terminated by us at any time and for any reason. However, the employment agreement provides for payments to her in the event of the termination of her employment in specified termination situations.

Termination without cause, for good reason or in connection with a change in control. In the event that we terminate Ms. McBride’s employment without cause, or Ms. McBride terminates her employment for good reason (as these terms are defined in her employment agreement), she will be entitled to receive a sum equal to (i) one times her then-current base salary paid in equal installments on our normal payroll schedule over the 12-month period following termination and (ii) an amount equal to her then-current target bonus, pro-rated for the portion of the year that she was employed by us and paid in equal installments on our normal payroll schedule over the 12-month period following termination.

55

amount of her COBRA premiums) until the earlier of (a) 12 months from separation, (b) the expiration of COBRA eligibility or (c) the date she or her dependents become eligible for health insurance coverage through new employment. In the event that such termination occurs within the period commencing one month before the effective date of a change in control and ending on the date that is 12 months after the effective date of a change in control (as defined in our 2015 equity incentive plan), then the cash severance amounts described above shall be paid to her in a single lump sum and in addition to such cash severance payment, the bonus amount described above shall not be pro-rated and 100% of her then-outstanding time-based vesting equity awards will become vested and exercisable, as applicable, pursuant to the terms of the applicable equity award agreements and her then-outstanding performance-based vesting equity awards will continue to be governed in all respects by the terms of the applicable equity award agreements.

CEO Pay-Ratio Disclosure

Under the Dodd-Frank Wall Street Reform and Consumer Protection Act and the related SEC rules, we are required to provide to our stockholders specified disclosure regarding the relationship of CEO total compensation to the total compensation of our median employee, referred to as “pay-ratio” disclosure.

For fiscal 2021, the median of the annual total compensation of all employees of our Company (other than the CEO) was $151,506 and the annual total compensation of the CEO, as reported in the Summary Compensation Table included in this Proxy Statement, was $5,402,931. Based on this information, the ratio of the annual total compensation of the CEO to the median of the annual total compensation of all employees was 36 to 1. Set forth below is a description of the methodology, including any material assumptions, adjustments and estimates, we used to identify the median employee for purposes of calculating our pay ratio.

57

To determine our total population of employees as of December 31, 2021, we included all full-time, part-time, seasonal and temporary employees, including employees of consolidated subsidiaries. Approximately 501 of our 543 employees are located in the United States, while approximately 34 employees are located in Russia, six are located in the United Kingdom, and two are located in Australia. We also did not include any contractors or other non-employee workers in our employee population.

To identify our median employee from our employee population as of December 31, 2021, we calculated the aggregate amount of each employee’s 2021 base salary (using the hours worked during 2021 for hourly employees (including overtime pay) and actual salary earned for our remaining employees), the cash amount of annual bonuses and retention bonuses for 2021 performance, the grant date fair value of equity awards granted in 2021, our contributions to life, accident and long-term disability benefits for employees and the matching contributions we provide to employees under our 401(k) plan. In making this determination, we annualized the base salary and base wages (but excluded overtime pay) of employees who were employed by us for less than the entire fiscal year. Using this approach, we selected the employee at the median of our employee population, who was based in the United States.

We calculated annual total compensation for this median employee to determine our pay ratio calculation for fiscal 2021 using the same methodology we use for our named executive officers in our Summary Compensation Table.

The pay ratio above represents our reasonable estimate calculated in a manner consistent with SEC rules and applicable guidance. The SEC rules and guidance provide significant flexibility in how companies identify the median employee, and each company may use a different methodology and make different assumptions particular to that company. As a result, and as explained by the SEC when it adopted these rules, in considering the pay ratio disclosure, stockholders should keep in mind that the rule was not designed to facilitate comparisons of pay ratios among different companies, even companies within the same industry, but rather to allow stockholders to better understand and assess each particular company’s compensation practices and pay ratio disclosures.

Director Compensation

The table below provides summary information concerning compensation paid or accrued by us during 2021 to or on behalf of our non-employee directors for services rendered during 2021. Messrs. Desch and Fitzpatrick and Ms. McBride, who are executive officers in addition to being directors, did not receive any separate compensation for service in their capacity as a director, and accordingly they are not included in this table.

We have had a compensation policy for non-employee directors in effect since 2010 that has been reviewed annually by our Board and periodically amended. Under the policy in effect for 2021, each non-employee director was eligible to receive compensation as outlined below:

	Annual Retainer
Committee	Chair		Member
Board of Directors	$	50,000	$	175,000
Audit Committee	$	40,000	$	20,000
Compensation Committee	$	15,000	$	7,500
Nominating and Corporate Governance Committee	$	10,000	$	5,000
Government Advisory Committee	N/A		$	15,000

In the fall of 2020 and again in 2021, our Compensation Committee retained Radford to conduct a review of our non-employee director compensation program. As part of its review, Radford provided the Compensation Committee with the following services:

•reviewed the companies in our current peer group in relation to non-employee director compensation;

•reviewed our non-employee director compensation practices relative to the market;

•provided a detailed competitive assessment of our non-employee director compensation program, including cash compensation, equity compensation, additional committee compensation, board chair compensation and equity vesting features;

•provided an overview of corporate governance considerations for non-employee director compensation, including stock ownership guidelines; and

58

•provided recommendations for adjustments to our non-employee director compensation program for the following year.

The amounts set forth above were established for our 2019 fiscal year. No changes were made to non-employee director compensation amounts for 2020, 2021 or 2022.

At the beginning of each year, each non-employee director can elect to have up to $50,000 of the annual $175,000 retainer for serving on the Board paid in cash, RSUs or a combination of both. The remaining $125,000 of the annual Board retainer is entirely paid in RSUs. In addition, the Chairman of the Board and chairman and member of each committee may elect to have the retainers for their positions paid in RSUs, cash or a combination of both. The cash component of director compensation is paid on a quarterly basis, and all RSU awards are granted in January and vest in full on the first anniversary of the grant date. Vested RSUs will be settled six months after the termination of the director’s service or upon a specified change in control of our Company, if it occurs earlier.

Our stockholders have approved an annual limit of $400,000 on the maximum grant date fair value of shares of our common stock subject to stock awards that may be granted to any non-employee director during a calendar year, taken together with any cash fees paid to the non-employee director for that calendar year.

(1)Amounts in this column represent the aggregate grant date fair values, computed in accordance with FASB ASC Topic 718 but excluding estimated forfeitures, of RSU awards issued pursuant to our non-employee director compensation policy on January 6, 2021. Effective July 1, 2021, Mr. Frazier was appointed to the Audit Committee, and was awarded one-half of the member retainer, or $10,000, which he chose to receive in RSUs. Mr. Schliemann was added to the Nominating Committee, and was awarded one-half of the member retainer, or $2,500, which he elected to receive in cash. Mr. Olson left the Nominating Committee and joined the Compensation Committee. As such, he forfeited one-half of his retainer for serving on the Nominating Committee which was originally granted in RSUs, or 60 shares, and was awarded one-half of the member retainer for service on the Compensation Committee, or $3,750, which he chose to receive in RSUs. The grants made in connection with these July 1 committee changes were made on July 7, 2021. The grant date fair value of awards to directors was calculated using the closing price of our common stock on the grant date, which was $41.63 for grants made on January 6, 2021 and $39.06 for grants made on July 7, 2021. These amounts do not correspond to the actual value that may be realized by the director upon vesting of such awards.

(2)The aggregate number of shares underlying RSU awards outstanding at December 31, 2021 and held by each non-employee director was as follows: 4,983 shares for Mr. Krongard; 4,803 shares for Mr. Canfield; 4,719 shares for Admiral Olson; 4,383 shares for Mr. Niehaus; 4,298 shares for Mr. Frazier; 3,962 shares for Mr. Rush; and 3,002 shares for each of Ms. Harman and Messrs. Pfeiffer, Schliemann and West. Additionally, the aggregate number of shares underlying unexercised stock option awards outstanding at December 31, 2021 and held by each non-employee director was as follows: 94,131 shares for Mr. Niehaus; 44,393 shares for Mr. West; and 3,750 shares for Mr. Olson.

(3)Includes fees for services as a chair or member as applicable, as set forth in the annual retainer table above.

TRANSACTIONSWITH RELATED PARTIES

RELATED PERSON TRANSACTIONS POLICYAND PROCEDURES

We have adopted a written Related Person Transactions Policy that sets forth our policies and procedures regarding the identification, review, consideration and approval or ratification of “related person transactions.” For purposes of our policy only, a “related person transaction” is a transaction, arrangement or relationship, or any series of similar transactions, arrangements or relationships, in which we and any “related person” are participants involving an amount that exceeds $120,000. Transactions involving compensation for services provided to us as an employee, director, consultant or similar capacity by a related person are not covered by this policy. A related person is any executive officer, director, or more than 5% stockholder of us, including any of their immediate family members, and any entity owned or controlled by such persons.

Under the policy, where a transaction has been identified as a related person transaction, management must present information regarding the proposed related person transaction to the Audit Committee (or, where Audit Committee approval would be inappropriate, to another independent body of the Board) for consideration and approval or ratification. The presentation must include a description of, among other things, the material facts, the interests, direct and indirect, of the related persons, the benefits to us of the transaction and whether any alternative transactions were available. To identify related person transactions in advance, we rely on information supplied by our executive officers, directors and certain significant stockholders. In considering related person transactions, the Audit Committee takes into account the relevant available facts and circumstances including, but not limited to (a) the risks, costs and benefits to us, (b) the impact on a director’s independence in the event the related person is a director, immediate family member of a director or an entity with which a director is affiliated, (c) the terms of the transaction, (d) the availability of other sources for comparable services or products and (e) the terms available to or from, as the case may be, unrelated third parties or to or from employees generally. The policy requires that, in determining whether to approve, ratify or reject a related person transaction, the Audit Committee consider, in light of known circumstances, whether the transaction is in, or is not inconsistent with, the best interests of us and our stockholders, as the Audit Committee determines in the good faith exercise of its discretion.

HOUSEHOLDINGOF PROXY MATERIALS

The SEC has adopted rules that permit companies and intermediaries (e.g., brokers) to satisfy the delivery requirements for annual meeting materials with respect to two or more stockholders sharing the same address by delivering a single set of annual meeting materials addressed to those stockholders. This process, which is commonly referred to as “householding,” potentially means extra convenience for stockholders and cost savings for companies.

This year, a number of brokers with account holders who are our stockholders will be householding our proxy materials. A single set of annual meeting materials will be delivered to multiple stockholders sharing an address unless contrary instructions have been received from the affected stockholders. Once you have received notice from your broker that they will be householding communications to your address, householding will continue until you are notified otherwise or until you revoke your consent. If, at any time, you no longer wish to participate in householding and would prefer to receive a separate set of annual meeting materials, please notify your broker or us. Direct your written request to Iridium Communications Inc., Attention: Secretary, 1750 Tysons Boulevard, Suite 1400, McLean, VA 22102. Stockholders who currently receive multiple copies of the annual meeting materials at their addresses and would like to request householding of their communications should contact their brokers.

OTHER MATTERS

The Board of Directors knows of no other matters that will be presented for consideration at the annual meeting. If any other matter is properly presented at the meeting, your proxyholder (one of the individuals named on your proxy card) will vote your shares using his or her best judgment.
