To Our Shareholders:

 We cordially invite

Insmed is at the precipice of what I believe will be the most significant period in our history. Against a backdrop of geopolitical and macroeconomic turbulence, our organization is growing by design and accelerating into an unbelievable transformation. Our strategy is to leverage potential revenues from our first three pillars—ARIKAYCE, brensocatib, and TPIP—to fund our fourth pillar, early-stage research, anchored by central support functions that act responsively to the different operating tempos of each program. In 2023, you will begin to attendsee key data readouts and development milestones from across all four pillars, leading up to the 2020 Annual Meetinganticipated reveal of Shareholderstopline data from the Phase 3 ASPEN study of brensocatib in patients with bronchiectasis in the second quarter of 2024.

On behalf of the Board of Directors, I would like to thank you for your ongoing support of Insmed Incorporated (Insmed)and your belief in our vision to become a globally recognized leading biotechnology company.

2022 ACHIEVEMENTS

2022 was a year of execution for Insmed, during which we laid the groundwork for the transformation upon which we have now embarked. We continued to focus on the successful commercialization of ARIKAYCE in the U.S., Europe, and Japan, and achieved a 30% increase in global revenues compared to 2021. We also advanced the post-marketing confirmatory frontline clinical trial program of ARIKAYCE in patients with NTM lung disease caused by MAC. Our ARISE trial fully enrolled in 2022 and our ENCORE study is expected to complete enrollment by the end of 2023.

Throughout 2022, we continued to advance the Phase 3 ASPEN study of brensocatib in bronchiectasis and have completed enrollment in adult patients in this study as of March 31, 2023. We also advanced a Phase 2 pharmacokinetics/pharmacodynamics study of brensocatib in patients with cystic fibrosis and reported topline results from this study in early 2023. We continued to advance the Phase 2 development of TPIP and made meaningful progress on our early-stage research programs, encompassing a wide range of technologies and modalities.

4INSMED PROXY STATEMENT


Finally, we strengthened our cash position significantly by completing three strategic financings resulting in aggregate gross proceeds of $775 million. We ended the year with approximately $1.15 billion in cash, cash equivalents, and marketable securities, putting us in a strong financial position that will take us through the key anticipated milestones over the next year and a half.

OUR CULTURE

At Insmed, we are powered by a shared sense of purpose to serve patients with serious and rare diseases. Driven by our core values of collaboration, accountability, passion, respect, and integrity, we have built a strong and unique culture in which employees feel motivated to do their best work and empowered to deliver on the promise of great science. In 2022, we were honored to be named Science magazine’s No. 1 Top Employer for the second year in lighta row.

ESG STRATEGY

Insmed has always held a strong sense of corporate citizenship, and as our company grows, we continuously challenge ourselves to do better. Since 2021, we have advanced a more formal framework to enhance our focus on environmental, social, and governance (ESG) matters, led by an ESG working group and sponsored by members of our Executive Committee. Our Nominations and Governance Committee is tasked with overseeing our ESG strategy and, along with the full Board, receives regular updates on ESG matters. We look forward to publishing our inaugural Responsibility Report in 2023.

COMMITMENT TO SHAREHOLDERS

We are grateful to you, our shareholders, for your support of Insmed. We are committed to providing long-term, sustainable growth and believe that remaining focused on the needs of our patients and their families will yield these results. We look forward to your continued support and feedback in 2023.

Sincerely yours,

GENERAL INFORMATION ABOUT THE ANNUAL MEETING AND VOTING

Distribution of Proxy Solicitation and Other Required Annual Meeting Materials

              The Board of Directors (the Board) of Insmed Incorporated is soliciting your proxy for the Annual Meeting of Shareholders on May 12, 2020, at 9:00 a.m. Eastern time (the Annual Meeting), and any adjournment or postponement thereof. Due to the COVID-19 pandemic and related public health concerns, the Annual Meeting will be held virtually via the Internet at www.virtualshareholdermeeting.com/INSM2020. We intend to make the Proxy Statement and related proxy materials available to our shareholders on or about March 31, 2020.

Information about the Annual Meeting and Voting at or Prior to the Annual Meeting

Why Did I Receive a One-page Notice in the Mail Regarding the Internet Availability of Proxy Materials this Year Instead of a Full Set of Proxy Materials?

              Pursuant to rules adopted by the SEC, we have elected to mail to many of our shareholders a Notice of Internet Availability of the Proxy Materials (the Notice) instead of a paper copy of the proxy materials. All shareholders receiving the Notice will have the ability to access the proxy materials over the Internet and receive a paper copy of the proxy materials by mail on request. Instructions on how to access the proxy materials over the Internet or to request a paper copy may be found in the Notice. In addition, the Notice contains instructions on how you may request proxy materials in printed form by mail or electronically on an ongoing basis. This process has allowed us to expedite our shareholders' receipt of proxy materials, lower the costs of distribution and reduce the environmental impact of our Annual Meeting.

Who May Vote Shares in Connection with the Annual Meeting?

              Shareholders of record at the close of business on March 18, 2020 (the Record Date), will be entitled to notice of and to vote at the Annual Meeting. As of the Record Date, we had 89,859,549 outstanding shares of our common stock, $0.01 par value per share (the Common Stock). Each share of our Common Stock entitles the holder to one vote with respect to all matters submitted to shareholders at the Annual Meeting. Beneficial owners of shares of our Common Stock may direct the record holder of the shares on how to vote the shares held on their behalf.

Who may participate in the Annual Meeting?

              This year's Annual Meeting will take place virtually through the Internet, in light of the COVID-19 pandemic and related public health concerns. We have designed the format of this year's Annual Meeting to ensure that our shareholders who attend the Annual Meeting will be afforded the same rights and opportunities to participate as they would at an in-person meeting. You are entitled to attend and participate in the Annual Meeting only if you were a shareholder of record as of the close of business on the Record Date, or if you hold a valid proxy for the meeting, as described below. To be admitted to the Annual Meeting at www.virtualshareholdermeeting.com/INSM2020, you must enter the

If you do not have a control number, please contact the brokerage firm, bank, dealer, or other similar organization that holds your account as soon as possible so that you can be provided with a control number.Proposal No. 1

 What is a Shareholder of Record and How Can I Vote if I am a Shareholder of Record?

              If, as of the close of business on the Record Date, shares of our Common Stock were registered directly in your name with our transfer agent, then you are a shareholder of record. As a shareholder of record, you may vote by proxy in advance or at the Annual Meeting.

              If you are a shareholder of record, you may vote or submit a proxy as follows:

    1.
    By Internet

    Before the Annual Meeting—You may authorize the voting of your shares by following the "Vote by Internet" instructions set forth on the Notice or proxy card through 11:59 p.m. Eastern Time on Monday, May 11, 2020. You must specify how you want your shares voted or your vote will not be completed and you will receive an error message.

    During the Annual Meeting—You may vote online during the Annual Meeting. You may cast your vote electronically during the Annual Meeting using the 16-digit control number found on your proxy card or other proxy materials and following the instructions at www.virtualshareholdermeeting.com/INSM2020.

    2.
    By Telephone—Dial 1-800-690-6903 using any touch-tone phone to transmit your voting instructions through 11:59 p.m. Eastern Time on Monday, May 11, 2020. Have your proxy card in hand when you call and follow the voting instructions given to you over the phone.

    3.
    By Mail—Complete and sign the proxy card and mail it in accordance with the instructions on the proxy card. Completed proxy cards must be received by 11:59 p.m. Eastern Time on Monday, May 11, 2020.

              In all cases, your shares will be voted according to your instructions.

What is a Beneficial Owner of Shares and How Can I Vote if I am a Beneficial Owner?

              If, on the Record Date, your shares of our Common Stock were not held in your name with our transfer agent, but instead were held in an account at a brokerage firm, bank, dealer, or other similar organization, then you are the beneficial owner of shares held in "street name," and these proxy materials have been forwarded to you by that organization. The organization holding your account is considered to be the shareholder of record of shares of our Common Stock for purposes of voting at the Annual Meeting and is required to vote those shares in accordance with your instructions. If you do not give instructions to the organization holding your account, then the organization will have discretion to vote the shares with respect to "routine" matters but will not be permitted to vote the shares with respect to "non-routine" matters. See "What Matters at the Annual Meeting are 'Routine' and 'Non-Routine'?" below. As a beneficial owner, you are invited to attend the Annual Meeting via the Internet at www.virtualshareholdermeeting.com/INSM2020. If you are a beneficial owner and not the shareholder of record, you may not vote your shares at the Annual Meeting unless you request and obtain a valid proxy from your broker or other agent.


Table of Contents

What if I Need Technical Assistance During the Annual Meeting?

              We encourage you to access the Annual Meeting before it begins. Online check-in will start shortly before the meeting on May 12, 2020. 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 Annual Meeting log-in page.

What is the Quorum Requirement?

              A quorum of shareholders is necessary to hold the Annual Meeting. Shares of our Common Stock representing a majority of the votes entitled to be cast on a matter at the Annual Meeting (or 44,929,775 shares as of the Record Date) will constitute a quorum for the transaction of business with respect to such matter, unless otherwise provided by law or in our Articles of Incorporation, as amended (Articles of Incorporation). Votes withheld, abstentions and broker non-votes count as present for establishing a quorum.

What Matters at the Annual Meeting are "Routine" and "Non-Routine"?

              Proposal 1, the election of Class II directors, Proposal 2, the advisory vote on the 2019 compensation of our named executive officers, and Proposal 4, the approval of an amendment to the Insmed Incorporated 2019 Incentive Plan (the 2019 Incentive Plan), are non-routine matters. Proposal 3, the ratification of the appointment of our independent registered public accounting firm, is a routine matter. If you are a beneficial owner of shares of our Common Stock and do not instruct your broker or other agent how to vote, your shares will not be voted on "non-routine" matters and your shares will be "broker non-votes" with respect to those proposals.

What are the Voting Requirements to Approve Each Proposal to be Submitted to Shareholders?

              The vote required to elect directors and approve each of the matters scheduled for a vote at the Annual Meeting is set forth below:

ProposalVote RequiredBoard Recommendation
1.    Election of three Class II directorsPlurality of votes castFOR
2.    Advisory vote to approve the 2019 compensation of our named executive officersMajority of votes castFOR
3.    Ratification of appointment of Ernst & Young LLP (Ernst & Young) as our independent registered public accounting firm for the year ending December 31, 2020Majority of votes castFOR
4.    Approval of an amendment to the 2019 Incentive PlanMajority of votes castFOR

              Proposal 1, the election of Class II directors, requires a plurality of the votes cast. This means that the three nominees who receive the highest number of affirmative votes cast will be elected irrespective of how small the number of affirmative votes is in comparison to the total number of shares voted. Our Board, however, has adopted a director resignation policy, under which a director nominee in an uncontested election must submit his or her resignation for consideration by our Nominations and Governance Committee and our Board if the number of votes withheld with respect to such director's election exceeds the number of votes "for" such director's election. See "Corporate Governance—Corporate Governance Matters—Director Resignation Policy" for additional information.


Table of Contents

              Proposal 2, the advisory vote on the 2019 compensation of our named executive officers, is not binding on, nor does it overrule, any decisions of the Company, the Board or the Compensation Committee. We value the input of our shareholders, and in the event that Proposal 2 is not approved by a majority of votes cast, the Board and the Compensation Committee will consider our shareholders' concerns and evaluate what actions, if any, may be appropriate to address those concerns.

              Proposal 3, the ratification of the appointment of Ernst & Young as our independent registered public accounting firm for the year ending December 31, 2020, does not require shareholder ratification under Virginia law, our Articles of Incorporation, or our Amended and Restated Bylaws (Bylaws). However, the Board is submitting the appointment of Ernst & Young to the shareholders for ratification as a matter of good corporate governance. In the event that Proposal 3 is not approved by a majority of votes cast, the Audit Committee will consider the vote in future independent auditor selection decisions.

              Proposal 4, the approval of an amendment to the 2019 Incentive Plan, requires the affirmative vote of a majority of the votes cast at the Annual Meeting.

What Is the Effect of Votes Withheld, Abstentions and Broker Non-Votes On Each of the Proposals?

              Votes that are withheld or any abstentions from voting will not be counted in determining the number of votes cast with respect to any of the proposals. As explained above, because Proposals 1, 2 and 4 are considered "non-routine," if a beneficial owner does not instruct the broker or other agent how to vote the shares, broker non-votes will result. Broker non-votes will not be counted in determining the number of votes cast with respect to these proposals. Because Proposal 3 is considered "routine," the broker or other agent will have discretion to vote any shares with respect to which a beneficial owner does not provide instructions, and no broker non-votes will occur with respect to this proposal.

What if I Submit a Proxy But Do Not Specify How I Would Like to Vote?

              If we receive a signed and dated proxy card or receive your instructions by Internet or by telephone and your instructions do not specify how your shares are to be voted, your shares will be voted as follows:

      FOR the election of each of the three Class II nominees for director;

      FOR the approval of the 2019 compensation of our named executive officers;

      FOR the ratification of the appointment of Ernst & Young as our independent registered public accounting firm for the year ending December 31, 2020; and

      FOR the approval of an amendment to the 2019 Incentive Plan.

              Unsigned proxy cards will not be voted.

What If Other Matters Not on the Proxy Card Are Brought Before the Annual Meeting for Action by the Shareholders?

              As of the date of this Proxy Statement, the Board does not intend to present any matters other than those described herein at the Annual Meeting and is not aware of any matters to be presented by other parties. If other matters are properly brought before the Annual Meeting, or any adjournment or


Table of Contents

postponement thereof, for action by the shareholders, proxies will be voted in accordance with the recommendation of the Board or, in the absence of such a recommendation, in accordance with the judgment of the proxy holders.

How Can I Revoke a Proxy Once I Have Voted?

              Anyone giving a proxy may revoke it at any time before it is exercised by voting at the Annual Meeting or by delivering, including by phone or Internet, a later dated proxy or written notice of revocation to our Corporate Secretary. Attendance at the Annual Meeting will not itself revoke a proxy. A proxy, if executed, properly delivered and not revoked, will be voted at the Annual Meeting.

What is the Expected Cost of Soliciting Proxies and Who Will Pay for this Cost?

              We will pay the cost of soliciting proxies. In addition to the use of mail and e-mail, proxies may be solicited in person or by telephone by our employees, with no additional remuneration. We have engaged The Proxy Advisory Group, LLC to assist in the solicitation of proxies and provide related advice and informational support, for a service fee, plus customary disbursements, which are not expected to exceed $15,000 in total.

PROPOSAL NO. 1


ELECTION OF CLASS II DIRECTORS

 

Our Bylaws currently provide that our Board will consist of not less than six or more than 10 directors. Our Board has adopted resolutions providing for up to nine10 directors. The directors are divided into three classes—Class I, Class II, and Class III. Each class of directors serves for three years on a staggered term basis, and the term of our Class II directors will expire at the Annual Meeting. Accordingly, the Board has nominated Elizabeth McKee Anderson, Clarissa Desjardins, Ph.D., and David W.J. McGirr and Elizabeth McKee Anderson for election as Class II directors.

Each of the nominees was recommended for election by the Nominations and Governance Committee, and such recommendation was approved by the Board. If elected, the term of office for these nominees will expire at our 20232026 Annual Meeting of Shareholders. If one of these bona fide nominees set forth in this Proxy Statement is unable to serve or for good cause will not serve, proxy holders may vote for another nominee proposed by the Board or, as an alternative, the Board may reduce the number of directors to be elected at the Annual Meeting. The information below describes the primary experience, qualifications and skills of Ms. Anderson, Dr. Desjardins, and Mr. McGirrMcGirr.

Each committee chairmanchair reports to the Board regarding the committee'scommittee’s considerations of management'smanagement’s processes for identifying, evaluating, and controlling significant risks. In addition, the officers responsible for oversight of particular risks within the Company provide updates and information to our Board. The Board considers specific risk topics, including risks associated with our strategic plan, our capital structure, our research and developmentR&D activities, our manufacturing and supply chain, and our operations. Our Board believes that full and open communication between management and the Board is essential for effective risk management and oversight. The Board and each of its committees have full access to our senior management, as well as the ability to engage outside advisors and other experts. Management routinely informs the Board of developments that could affect our risk profile or other aspects of our business and development.

The Audit Committee is responsible for overseeing the Company'sCompany’s program for identifying, evaluating, and controlling significant risks. The Audit Committee periodically discusses with management and the independent auditor the Company'sCompany’s major risk exposures, including financial, legal, regulatory, and cybersecurity risk exposures, and the steps taken to monitor, control and minimize such exposures. The Audit Committee also reviews and evaluates our processes and policies for identifying and assessing key risk areas and for formulating and implementing steps to address such risk areas. The Audit Committee oversees disclosure controls and procedures, including applicable internal control over financial reporting and meets with the Chief Financial Officer, the Chief Legal Officer, the Chief Compliance Officer,General Counsel, the Chief Accounting Officer, external audit personnel, and other senior managers as appropriate to review issues regarding compliance with the applicable legal and regulatory requirements.

The Compensation Committee assesses and monitors whether any of our compensation policies and programs hashave the potential to encourage excessive risk taking. Our Compensation Committee engages an independent consultant to advise it on topics related to Board and executive compensation. In July 2019, the Company selected Willis Towers Watson as its new independent compensation consultant. In February 2019,2022, the Compensation Committee, with the assistance of Frederic W. Cook & Co., Inc. (FW Cook),WTW, the Company's formerCompensation Committee’s independent compensation consultant, reviewedconducted an in-depth risk review of the executive compensation program and sales incentive programs, and determined that the design of the compensation policies, including the components, weightings and focus of the elements, do not encourage management or employees that participate in the sales incentive plans to assume excessive or inappropriate risks. When approving the 2022 awards of performance-based restricted stock units (“PSUs”), described in the Compensation Discussion and Analysis, the Compensation Committee gave consideration to whether the conditions and design would promote inappropriate or excessive risk-taking. The Compensation Committee determined that the right governance protocols were in place and that the combination of performance requirements did not promote inappropriate risk-taking. In the first quarter of 2023, the Compensation Committee and WTW reviewed areas that had changed since the 2022 assessment and again found that our executive compensation program and sales incentive plans program do not encourage management to assume excessive or inappropriate risks.risks, and have appropriate safeguards and governance protocols in place.

Environmental, Social, and Governance Considerations

As a company driven by its mission to transform patients’ lives, we take our responsibility to patients, employees, the medical community, and the communities in which we live and work very seriously. As we grow, we are enhancing our focus on a variety of ESG considerations. Our Nominations and Governance Committee receives updates on ESG matters from our CEO, General Counsel, and ESG team, a cross-functional group of employees including members from corporate communications, investor relations, and legal. The ESG team works with employees across the organization in addressing ESG initiatives. While we continue to expand our ESG strategy, we already focus on the following areas:

 

PATIENT SUPPORT

Patients are at the center of our mission. We operate a robust patient support program, partake in regular, compliant interaction with patient advocacy groups and invite patients to share their experiences in-person and virtually. Furthermore, we are committed to providing patients with access to our medicines and work with numerous stakeholders to enable this access as appropriate. Our Expanded Access Programs help address patient needs by making certain investigational medical products or unapproved products available to eligible patients, in accordance with applicable local laws. Finally, we continue to monitor product safety in our clinical development programs and for our marketed product via our pharmacovigilance program.


 

DIVERSITY, EQUITY AND INCLUSION

We are committed to promoting diversity in our workforce and to taking steps to support equity and inclusion for all.

Gender – Women represent 67% of our Class II director nominees to serve until the 2026 Annual Meeting of Shareholders. As of the Record Date, women represented 33% of the Board and 37.5% of our Executive Committee. As of September 26, 2022 (the most recent measurement date and based on self-identified information), women comprised 51% of our overall workforce and 28% of our leadership (Vice President level and above).

Racial and Ethnic – As of the Record Date (based on self-identified information), 67% of our Board identifies as non-minority, 22% identifies as minority, and 11% did not identify. As of September 26, 2022 (the most recent measurement date and based on self-identified information), 67% of our US workforce identifies as non-minority, 32% identifies as minority, and 1% did not identify. As of the same date, 83% of our US leadership (Vice President level and above) identifies as non-minority, and 17% identifies as minority.

We will continue to measure and share our diversity statistics in the future. We expect to continue to enhance our Board, leadership and workforce diversity, advance the development of diverse talent, and ensure diverse succession plans in our employee workforce, leadership and our Board. In 2022, our Employee Resource Groups (“ERGs”) met routinely with the aim of fostering a sense of community and cultural awareness among our employees. Our current ERGs include groups supporting female employees, working caregivers and Hispanic/Latinx colleagues. Most recently, in February 2023, we announced the creation of a new ERG, BEING (Black Employees of Insmed Networking Group).


30INSMED PROXY STATEMENT


In 2022, we established an Inclusion Council that acts as an advisor to the Chief People Strategy Officer and senior leadership on our general strategy related to diversity, equity, inclusion, and belonging. In addition, we are committed to equitable pay for all employees and use industry benchmarks and annual compensation reviews to ensure a fair and bias-free compensation system.


 

EMPLOYEE WELLNESS

After receiving the same honors in 2021, we were again ranked as the top company to work for in the biopharma industry in Science’s 2022 Top Employers Survey and certified in the US as a Great Place To Work. Additionally, in 2022, we were ranked number 2 in Fortune’s 25 Best Small and Medium Workplaces in Biotechnology and Pharmaceuticals. We are dedicated to investing in our employees and workplace culture. As part of this effort, we have put in place several financial wellness programs for the benefit of our workforce, including an Employee Stock Purchase Plan and 401(k) match program.

In 2022, we introduced Thriveful, an internal platform offering a diverse array of programs and resources designed to support employee health, financial wellness, professional development and social wellbeing. Examples include health screenings, reproductive care benefits, financial and equity education, skills training, and opportunities for connectedness and relationship building.


 

COVID-19 SUPPORT

Our employees (other than our laboratory personnel) have been provided the ability to work virtually in order to flexibly manage business and home responsibilities. We have enhanced our internal communications and touch points to ensure connectivity to our workforce. We will continue to manage this situation with a focus on the safety of our employees, ARIKAYCE physicians, caregivers and patients.


 

ENVIRONMENTAL IMPACT

We are cognizant of our responsibility to our broader environment and have supported several green measures at our headquarters in an effort to reduce our Company’s carbon footprint, including increasing recycling efforts, using energy-efficient rooftop HVAC units, installing electric car chargers, and limiting waste in food service distribution. In our research laboratories, hazardous and chemical waste are responsibly managed and tracked in line with regulatory requirements. We continue to explore ways to improve our sustainability efforts.


 

COMMUNITY SERVICE

We are committed to giving back to our communities, with a focus on three key areas: health, education, and human services. We partake in several employee-led community service initiatives both in the US and abroad.

In 2022, we held our inaugural Global Day of Good, a company-wide community service effort. More than 500 employees participated globally in service activities that focused on three key areas of impact: health, education and human services. Volunteer activities focused on bringing positive change to the communities where employees live and work while exemplifying our core values.

Executive Summary of Our 20192022 Business and Strategic Achievements

We are a global biopharmaceutical company on a mission to transform the lives of patients with serious and rare diseases. Our first commercial product, ARIKAYCE, is approved in the US as ARIKAYCE® (amikacin liposome inhalation suspension), in Europe as ARIKAYCE Liposomal 590 mg Nebuliser Dispersion, and in Japan as ARIKAYCE inhalation 590mg (amikacin sulfate inhalation drug product). ARIKAYCE received accelerated approval in the United States (US)US in September 2018 for the treatment ofMycobacterium avium complex (MAC)(“MAC”) lung disease as part of a combination antibacterial drug regimen for adult patients with limited or no alternative treatment options in a refractory setting, as definedsetting. In October 2020, the European Commission (“EC”) approved ARIKAYCE for the treatment of nontuberculous mycobacterial (“NTM”) lung infections caused by patientsMAC in adults with limited treatment options who do not achieve negative sputum cultures after a minimumhave cystic fibrosis (“CF”). In March 2021, Japan’s Ministry of six consecutive monthsHealth, Labour and Welfare (“MHLW”) approved ARIKAYCE for the treatment of patients with NTM lung disease caused by MAC who did not sufficiently respond to prior treatment with a multidrug background regimen therapy. Nontuberculous mycobacterial (NTM)regimen. NTM lung disease caused by MAC (which we refer to as MAC lung disease) is a rare and often chronic infection that can cause irreversible lung damage and can be fatal.

 

In 2019,2022, our named executive officers played critical roles in the furtherance of our mission. We successfully completed our first yearcontinued to focus on the execution and successful US commercialization of commercializationARIKAYCE and subsequently have observed strong performancegrowth in US sales as compared to 2021. The Company also continued its efforts to advance ARIKAYCE globally and has achieved a 30% year over year increase from 2021 in global ARIKAYCE revenues. In Europe, the US launch of ARIKAYCE.

ARIKAYCE is now commercially available in Germany, France, the treatmentNetherlands, the United Kingdom, Italy, and Belgium.

In 2022, we also continued to advance the post-marketing confirmatory frontline clinical trial program of ARIKAYCE in patients with persistent MACNTM lung infection, and the filing was subsequently validated. In 2019, we also advanced our Japanese new drug application (JNDA), resultingdisease caused by MAC. The ARISE trial, an interventional study of ARIKAYCE designed to validate a patient-reported outcome (“PRO”) tool in the submission of the JNDA to Japan's Ministry of Health, Labour and Welfare (MHLW) in March 2020 for ARIKAYCE for the treatment of patients with MAC lung disease, who do not respond sufficientlyfully enrolled in 2022. The ENCORE trial is designed to prior treatment.

We currently have two parallel Phase 2 studies ongoing: a Phase 2 study in patients with PH-ILD over a 16-week treatment period to assess safety and tolerability and a Phase 2b study in PAH patients over a 16-week treatment period to evaluate the effect of TPIP on pulmonary vascular resistance and six-minute walk distance. In 2022, we continued to advance the Phase 2 development work in both PH-ILD and PAH.

 

Our early-stage research efforts are comprised of our preclinical programs, advanced through internal research and development and augmented through business development activities. In March 2021, we acquired a proprietary protein deimmunization platform, called Deimmunized by Design, focused on the reengineering of therapeutic proteins to evade immune recognition and reaction. In August 2021, we acquired Motus Biosciences, Inc. and AlgaeneX, Inc. preclinical stage companies engaged in the research, development and manufacturing of gene therapies for rare genetic disorders. In January 2023, we acquired Vertuis Bio, Inc., a privately held, preclinical stage company engaged in the research and development of gene therapies for rare genetic disorders. We believe that animal studies may demonstrate the viability of these potential medicines to address serious unmet medical needs in various therapeutic areas. Our initial therapeutic areas of focus include musculoskeletal, CNS, ocular, and rheumatologic diseases. We anticipate submitting our first IND filing in the first half of 2023. Preclinical data in musculoskeletal and CNS indications are also expected in the first half of 2023 and clinical data from the first trial in a musculoskeletal disease are anticipated in the first half of 2024.

More broadly from a strategic and operational standpoint, in 20192022 we expanded our leadership team with talented executives in key financial, medical, commercial, sales, and clinical roles.

Compensation Philosophy and Principles

 

We operate in a competitive, rapidly changing, and heavily-regulatedheavily regulated industry. The long-term success of our business requires us to be resourceful, adaptable, and innovative, and the skills, talent, and dedication of our executive officers are critical components to this success. Therefore, our compensation program for our executive officers, including our named executive officers, is designed to attract, retain, and incentivize the best possible talent. The Company'sCompany’s compensation program for named executive officers is structured to implement the following guiding principles:

              AlignmentAlign Executives’ Interests with Shareholder Interests.those of our Shareholders.

A significant portion of our named executive officers'officers’ compensation is in the form of equity awards based on our belief that equity awards align management'smanagement’s interests with the creation of futuresustainable long-term shareholder value. Executive officers are also subject to share ownership guidelines which require them to maintain a minimum interest in Insmed stock.

Use of "At-Risk"“At-Risk” Compensation to Incentivize Executives.

A substantial portion of our named executive officers'officers’ compensation is based on "at“at risk," or variable, compensation, such as annual cash incentives and stock options. We believe this mix of compensation best aligns the interests of our named executive officers with those of our shareholders over time and contributes to the achievement of short-term goals and the advancement of our long-term strategy through long-term goals. In 2019,2022, approximately 90% of our CEO'sCEO’s annual target direct compensation was "at“at risk," and 82%86% of our other named executive officers'officers’ annual target direct compensation was "at risk".“at risk.” Annual target direct compensation as shown below consists of base salary, the target annual incentive award and the grant date fair value of RSUs and stock options granted in 2022.

Pay for Performance.

We reward the named executive officers for attaining established businessCompany and individual goals. The attainment of these goals requires the named executive officer to dedicate his or her time, effort, skills and business experience to the long-term success of the Company and the maximization of shareholder value. A significant portion of the named executive officers'officers’ compensation is based both on Company and individual performance, and theour executive compensation program is designed to reward both short-term and long-term performance. Short-term performance of our named executive officers is principally rewarded through annual cash incentives that reflect the achievement of corporate goals and, with respect to named executive officers other than our President and CEO, individual goals. Long-term performance of our named executive officers is largely rewarded through stock option and RSU awards that are eligible to vest based on continued service and have a value tied to share price appreciation.

              Pay competitively In 2022, to attractalign a select group of senior leaders, that includes our NEOs, and retain skilledthem through a critical period for the company in relation to the brensocatib clinical trials, an incremental award of PSUs was also made. The vesting of these awards is subject to robust goals based on the achievement of key milestones within a defined window, and a total shareholder return (“TSR”) assessment relative to the Nasdaq Biotechnology Index (the “Nasdaq Biotech Index”). If the milestone conditions are not achieved, if TSR is negative or below the 25th percentile relative to the Nasdaq Biotech Index constituents, or if an executive officers.does not remain in continuous employment for a defined period, no PSUs will vest. This further aligns the compensation of our executives with the performance of Insmed, and our success in unlocking long-term value for our shareholders in a timely manner. If the milestones are not achieved, none of the PSUs will vest. Further details on the PSUs can be found in “2022 Performance-Based Restricted Stock Units”.

Pay Competitively to Attract and Retain Skilled Executive Officers.    The

Our executive compensation program is designed to allow the Company to attract and retain individuals whose skills are critical to the current and long-term success of the Company. Because competition for top talent is intense in our industry, institutional knowledge is of material value, and loss of critical talent can be highly disruptive, retention is a key objective of theour executive compensation program. The compensation program is designed to

appropriately compensate our executive officers for the success of the Company from a competitive standpoint, so that they remain with the Company and continue to contribute to the Company'sCompany’s long-term success. We seek to achieve this objective by setting target compensation levels appropriately relative to market, granting equity as a combinationthat vests based on continued service, and, in respect of the PSU awards, the additional achievement of performance milestones. Stock options further enhance retention given their alignment with long-term stock optionsprice performance, and RSU awards.provisions that reduce exercise periods to no longer than three months on separation.

Say on Pay.

At our 20192022 Annual Meeting, of Shareholders, we held an advisory vote on the compensation of our named executive officers. OverApproximately 95% of the shares voted were voted in favor of our say-on-pay proposal. Additionally, the Company has discussed executive compensation matters with certain of our investors. The Compensation Committee considered these voting results and discussions and believes they affirm the Company'sCompany’s compensation philosophy and the principles discussed above.

Corporate Governance Perspectives on our Executive

Compensation Program

 

We believe that our executive compensation program reflects our commitment to strong corporate governance practices as evidenced by the following aspects of our executive compensation program:program reflect our commitment to strong corporate governance:

      Our Compensation Committee has overall responsibility for executive compensation plans, policies, and programs, although our independent Board members approve recommendations made by our Compensation Committee regarding the compensation of our President and CEO;

Performance metrics that govern incentive compensation are definedestablished by our Compensation Committee at the start of each fiscal year and are reviewed by our Compensation Committee at the end of the year;

Our executive compensation program, in the aggregate, rewards performance in a variety of ways, aimed at a balanced assessment based onand aims to drive the Company'sCompany’s strategic objectives;

Individual

Payouts made pursuant to individual and corporate multiplier ranges in our incentive compensation program are developed and implemented such that payouts are capped at a predetermined maximum amount, irrespective of performance that exceeds objectives;

Our Compensation Committee has the ability to exercise its discretion to reduce or eliminate incentive compensation payouts;

We have several risk mitigation policies, detailed below, including an annual compensation risk review that includes sales plans below the executive level, share ownership guidelines, in place for our Presidenta compensation recoupment policy, and CEO, pursuant to which he must hold shares of Common Stock, vested in-the-money stock optionsan insider trading policy with anti- hedging and unvested restricted stock units in an aggregate amount equal to at least three times his base salary within 5 years of the adoption of the guidelines or date of hire, whichever is later.

    43INSMED PROXY STATEMENT


    Risk Mitigation Policies and

    Practices

    Insmed recognizes the importance of a robust risk management environment, and our compensation programs are an important part of this.

    Annual Compensation Risk Review.

    Each year the Compensation Committee receives an update on the global incentive compensation programs and executive compensation program to identify potential areas of risk and actions taken to mitigate that risk. These reviews seek to determine whether each risk is appropriate, and that sufficient controls are in place from a governance standpoint. The 2022 update confirmed that no inappropriate risks were identified. The Compensation Committee does not believe that our executive compensation program is reasonably likely to have a material adverse effect on the Company based on our compensation philosophy and principles and the governance principles described above.

    Stock Ownership Guidelines.

    Senior executives, including all of our named executive officers, are subject to stock ownership guidelines which require them to maintain a minimum interest in Insmed Common Stock. These guidelines further align the interests of our executives with those of our shareholders, encourage them to think like long-term owners and stewards of the company, and discourage decisions focused only on the short-term.

    Minimum ownership requirement

    •  President & CEO: 300% of base salary

    •  Other named executive officers: 100% of base salary

    Equity interests considering in assessing compliance

    •  Common Stock held by the executive (directly or indirectly)

    •  Stock options that are fully vested and in-the-money

    •  Restricted stock units that are unvested

    Time horizon for compliance•  Five years from date of appointment as a named executive officer

    Compliance with the guidelines is assessed annually, and to the extent an executive is not meeting their requirement or showing sufficient progress within the defined window, the Compensation Committee may take action. As of the Record Date, all named executive officers had satisfied their respective requirements.

    Compensation Recoupment Policy.

    Our recoupment policy allows our Board to recover cash incentive or equity-based compensation paid to an executive officer, including pursuant to the Insmed Incorporated 2019 Incentive Plan (the “2019 Incentive Plan”), in the three-year period preceding any year in which we are required to restate our financial results filed with the SEC as a result of the executive officer’s intentional misconduct.

    Insider Trading Policy.

    Our insider trading policy prohibits our employees, including officers and directors, from (i) engaging in hedging transactions (whether through the use of financial instruments such as prepaid variable forwards, equity swaps, collars, exchange funds, or otherwise) involving the Company'sCompany’s securities and (ii) pledging the Company'sCompany’s securities as collateral for loans of any type without the prior approval of the Chief Financial Officer or General Counsel. Executive officers seeking to pledge the Company’s securities as collateral must receive approval from the Compensation Committee. No such pledges were approved during 2019.

    2022.

     In addition, the Compensation Committee annually reviews a compensation risk assessment conducted by management. The Compensation Committee does not believe that our compensation program is reasonably likely to have a material adverse effect on the Company based on our compensation philosophy and principles and the governance principles described above.

    Executive Compensation Determination Process

    Role of the Compensation Committee and the Board in Making Compensation Decisions.

    Our Compensation Committee has been delegated the authority to make determinations regarding all elements of compensation for our executive officers, except for Mr. Lewis, our President and CEO. Our Compensation Committee recommends to our independent Board members the individual elements of total compensation for Mr. Lewis for approval. The independent Board members review this recommendation and determine the compensation for Mr. Lewis. As discussed in further detail below, in assessing executive compensation, our Compensation Committee engages an outside independent compensation consultant to assess the competitiveness of our programs and periodically conducts a peer group review.

    Role of Management.

    The Compensation Committee, in making executive compensation decisions, may solicit input from management as appropriate with respect to individual and Company performance and results. The Compensation Committee receives recommendations and evaluations from the President and CEO with respect to the compensation and performance of our named executive officers from the President and CEO (aside from his own compensation and performance) and Company performance. The Compensation Committee considered management'sthe President and CEO’s assessment along with the input of its independent compensation consultant when making 20192022 compensation decisions.decisions for our named executive officers (other than our President and CEO).

    Role of the Compensation Consultant.

    The Compensation Committee is authorized to select and retain its own independent compensation consultant and has routinely sought the advice of an independent compensation consultant regarding our executive compensation practices. During 2019, FW Cook advised the Compensation Committee2022, WTW, in addition to attending meetings, provided support on its compensation risk assessment, and provided data and recommendations onmatters including long-term incentive design, executive officer compensation. In December 2019, Willis Towers Watson provided a comprehensive review of long-term incentive guidelines for all employee levels, an unvested equity analysis to assess the retention power of ourand director compensation, program for senior executives,investor engagement, and

The Compensation Committee evaluates the independence of its compensation consultant on an annual basis and has concluded that each of FW Cook, its former compensation consultant, and Willis Towers Watson, its current compensation consultant,WTW was independent during their respectiveits tenure in 2019.2022.

    Shareholder Feedback.

    At our 2022 Annual Meeting, we held an advisory vote on the compensation of our named executive officers. Of the shares voted, approximately 95% were voted in favor of our say-on-pay proposal which indicates continued strong support for the design and operation of our executive compensation program. Additionally, as part of ongoing engagement between the Company and investors, we provide a forum for direct feedback on executive compensation matters. The Compensation Committee considers the say-on-pay outcome, proxy advisor views, and any feedback received from investors annually when reviewing the compensation program.

    Taking into account the sustained high voting outcome and feedback received, the Compensation Committee believes this reaffirms the Company’s compensation philosophy, design, and operation as disclosed in this Compensation Discussion and Analysis.

    Compensation Evaluation Processes and Criteria.

    Given the high demand for the experienced and well-qualified executives we seek to employ, the Compensation Committee reviews data and information from a variety of sources such as outside surveys of compensation and benefits for executive officers in the biotechnology industry, as well as public information regarding executive compensation at peer biotechnology companies. The Compensation Committee also draws upon the personal knowledge of its members with respect to executive compensation at comparable companies.

     

    In determining the amount and composition of compensation elements (cash and non-cash elements and short- and long-term elements) for our non-CEOeach named executive officers,officer other than the President and CEO, our Compensation Committee reviews the performance of each executive officer holistically. In setting compensation levels for our executivesuch officers for 2019,2022, our Compensation Committee considered many factors, including, but not limited to, the following factors:

        our achievement of certain product development, financial, strategic planning, and other goals;

    for each non-CEO named executive officer'sofficer other than the President and CEO, such officer’s individual performance against certain pre-established goals, as discussed in more detail below;

    the scope and strategic impact of each executive officer'sofficer’s responsibilities;

    our past business performance;

    our long-term goals and strategies;

    the experience of each executive officer;

    past compensation levels of each executive officer and of the executives as a group;

    internal equity and the relative levels of pay among executive officers;

    the amount of each element of compensation in the context of the executive officer'sofficer’s total compensation and other benefits;

    for each executive officer other than the President and CEO, the evaluations and recommendations of our President and CEO; and

    the competitiveness of our compensation relative to selected peer group companies and other survey data, which are described in detail below.

     

    Consideration of these factors is subjective. No relative weights or rankings are assigned to them except as otherwise discussed in this CD&A.

     

    For the President and CEO'sCEO’s compensation, the Compensation Committee reviews and evaluates the performance of the President and CEO and recommends to the independent Board members the individual elements of his total compensation, considering,compensation.

    experience, prior compensation levels, alignment of compensation outcomes and potential compensation with Company performance, retention concerns, our general performance objectives, as well asand the compensation practices of peer companies and the markets in which we compete for executive talent.

        Selection of Peer Companies and Benchmarking.

     In November 2018,

The peer group used to inform 2022 compensation was approved by the Compensation Committee upon advice received from FW Cook, its former compensation consultant, selected the companies that comprised our 2019 peer group through a screening process that consideredin August 2021. In assessing potential peers, consideration is given to publicly traded biopharmaceutical companies that are similar to usthe Company in numberterms of employees, market capitalization, revenue, research and stage of product development. This review resulteddevelopment expense, pipeline profile, and headcount. There is a focus on maintaining stability in modificationspeers over time, while ensuring the group remains sufficiently robust and relevant. The 2022 peer group reflects the following changes from our 20182021 peer group as describedgroup: (i) the removal of Immunomedics, Inc. following the completion of Gilead’s acquisition in 2020, and (ii) the addition of the companies that are marked by an asterisk below.

        Annual Long-term Equity IncentivesIncentives.

     

    One of the guiding principles of our executive compensation program is pay for performance, and we believe that a significant portion of our executives'executives’ compensation should be performance-based to create appropriate incentives and rewards for achieving strategic goals that are critical drivers of shareholder value. We also believe that stock ownership by management aligns our executives' interests with those of our shareholders, and equity incentive compensation rewards our executives for their contributions toIn addition, the long-term success of the Company. The Compensation Committee believes that equity-based compensation is a vital part of our compensation program as it creates an ownership culture that rewards our executives for maximizing shareholder value over time and alignsconsiders the interests of our named executive officersfollowing in approving equity plan design and other key employees with those of our shareholders.award values:

     The Compensation Committee believes that the combination of stock option and RSU awards to our named executive officers and other employees encourages retention and aligns the interests of employees and our shareholders.

    Equity-based compensation creates an ownership culture that rewards our executives for maximizing shareholder value sustainably over time, and, in combination with stock ownership, aligns our executives’ interests with those of our shareholders

    Equity incentives reward our executives for their contributions to the long-term success of the Company

    The combination of stock options and RSUs drives performance and a long-term mindset while encouraging retention

    We believe stock options are a form of performance-based incentive compensation because they require stock price appreciation to deliver value to the holder, thereby aligning compensation earned with value shareholders receive over the same period of time

    In determining the equity compensation awards to grant to our named executive officers in 2019,2022, the Board, with respect to our President and CEO, and the Compensation Committee, with respect to our remaining named executive officers, considered each named executive officer'sofficer’s role, as

Individual performance prior to the grant date was also considered. Generally, 75% of the award value is made in the form of stock options and 25% of the award value is made in the form of RSUs.

    The Board, with respect to our President and CEO, and the Compensation Committee, with respect to our remaining named executive officers, may also grant equity awards from time to time in recognition of a named executive officer'sofficer’s expanded duties and responsibilities or continuing contributions to the Company'sCompany’s performance. In connection with Mr. Drayton’s promotion to Chief Commercial Officer, an additional award of stock options and RSUs was made to reflect his expanded role and to better align total compensation for his new role relative to market.

    Based on these considerations, our named executive officers received the following annual equity incentive awards in 2019.2022.

    The restricted stock units vest and become available as follows: 25% on each anniversary of the date of grant through the fourth anniversary date of the grant.

    (3)
    On November 18, 2019, Mr. Adsettnamed executive officers, also received an award of PSUs. These awards reflected a combination of objectives to complement the existing annual awards of stock options and RSUs, in connectionwhich included retaining senior leaders through a critical period related to brensocatib and aligning senior leaders with his promotionunlocking value for our shareholders on an appropriately aggressive timeline.

    The PSUs can vest upon the achievement of performance conditions based on brensocatib milestones, our TSR relative to Chief Operating Officer.

    (4)
    the Nasdaq Biotech Index constituents, and service, as summarized below. The Compensation Committee and Board believe these goals to be appropriately challenging with strong alignment to shareholder interests as it relates to the time horizon, total shareholder return modifier and final vesting being tied to the FDA accepting a new drug application (“NDA”) from Insmed for brensocatib. If the milestone conditions are not achieved, if Insmed’s TSR is negative or below the 25th percentile relative to the Nasdaq Biotech Index constituents, if an executive does not remain in continuous employment as explained below, or if the FDA does not accept the NDA, no PSUs will vest.

    57INSMED PROXY STATEMENT


    Milestone Conditions

    The issuance of a press release announcing certain top-line results from the ASPEN trial within a defined time horizon and the acceptance of an NDA by the FDA for brensocatib.

    If the milestone conditions are achieved, the PSUs would vest subject to the two further requirements summarized below.

    Relative TSR Modifier

    To ensure any results related to brensocatib align with the creation of value for our long-term shareholders, a relative TSR modifier will be applied to any PSUs that vest as a result of achieving the milestone conditions. TSR will be assessed through the 30-days following a press release filing, with comparisons made to the Nasdaq Biotech Index constituents as follows:

    ●    If Insmed’s TSR is negative, or if Insmed’s TSR ranks below the 25th percentile, no PSUs will vest regardless of milestone and service achievements

    ●    If Insmed’s TSR is at or above the 25th percentile and less than the 50th percentile, a 0.5x modifier will apply, reducing the number of PSUs that vest by 50%

    ●    If Insmed’s TSR is at or above the 50th percentile and less than the 75th percentile, a 1.0x modifier will apply

    ●    If Insmed’s TSR is at or above the 75th percentile, and less than the 90th percentile, a 2.0x modifier will apply

    ●    If Insmed’s TSR is at or above the 90th percentile, indicating significant value has been created for our shareholders relative to peers, a 2.5x modifier will apply 

    Service Conditions

    ●    To ensure PSUs meet the objective of retaining senior leaders during this period, a recipient must remain in continuous employment with the Company through the later of the third anniversary of the grant date and the date an NDA for brensocatib is accepted by the FDA.

    ●    If Insmed does not file an NDA due to the clinical trial results, or the FDA does not accept an NDA, for brensocatib, PSUs will not vest.

    58INSMED PROXY STATEMENT


    In determining the value of these incremental awards, the Compensation Committee considered the objectives of the award, the challenging nature of the performance goals and the target values for the annual equity grants. Based on these considerations, our named executive officers received the following PSU awards in 2022.

    Martina Flammer, M.D.1/6/202228,377
    Drayton Wise1/6/20226,149

    On the date the PSUs were granted, the performance conditions necessary for vesting were not deemed probable given the nature of the milestone goals. Accordingly, and reflecting the required accounting treatment for the PSUs, no value is attributed to them in the Summary Compensation Table at this time. In approving the awards, the Compensation Committee considered the potential value of the awards under various scenarios and determined that an increase to Ms. Pellizzari's awardappropriate “target” value would be 25% of restricted stock units was appropriate given her individual performance contributions.

    (5)
    Mr. Tombesi stepped down as our Chief Financial Officer,a named executive officer’s annual equity grant value if both the milestone goals and his employment with the Company ended in June 2019. He forfeited this option grant in its entirety at the time of his termination.

    a 1.0 relative TSR modifier were achieved.

        Other BenefitsBenefits.

     

    We maintain several other benefit programs that are offered to all employees including executives on an equivalent basis, which include coverage for health insurance, dental insurance, life and disability insurance, and a 401(k) plan. With respect to our 401(k) plan, the Company will deposit a matching contribution of 100% of deferrals up to 4% of an employee'semployee’s eligible compensation (subject to any maximum applicable limits under the Internal Revenue Service regulations). We also maintain an Employee Stock Purchase Plan whereby eligible employees, including executives, are given the opportunity to purchase Common Stock at a discounted price through payroll deductions. We do not have any defined benefit plans or non-qualified deferred compensation plans. From time to time, we may also provide employees with certain other limited perquisites. For instance, in 2019, we paid certain legal fees on Mr. Lewis' behalf, including in connection with his sale of shares of our Common Stock in a registered offering.

        Severance and Change in Control BenefitsBenefits.

     

    As discussed in further detail below,in “Potential Payments Upon Termination,” we have entered into employment agreements with each of our named executive officers that, in addition to other items, provide for certain severance and change in control payments. We believe that the existence of these potential benefits will discourage turnover and mitigate the influence of a potential change in control on an executive officer'sofficer’s decision-making due to concerns regarding job security. The employment agreements with our named executive officers do not provide for single-trigger vesting on a change in control or tax gross-up payments. In connection with the termination of Mr. Tombesi's employment, we entered into a separation agreement providing for certain cash and other benefits. See "Potential“Potential Payments Upon Termination"Termination” for additional information.

    2.PSUs were granted to our named executive officers on January 6, 2022 pursuant to the 2019 Incentive Plan. The PSUs vest upon the achievement of two performance conditions, a service condition, and a market condition. The performance conditions are the issuance of a press release announcing certain top-line results from the ASPEN trial within a defined time horizon and the acceptance of an NDA by the FDA for brensocatib. The service condition is continuous employment with the Company through the later of (i) the third anniversary of the grant date of the PSU award and (ii) the date an NDA for brensocatib is accepted by the FDA. The potential payout of the awards ranges from 0% to 250% of the target, dependent on a market condition that is based on the Company’s TSR compared to Nasdaq Biotech Index constituents.

    Potential Payments Upon Termination

     

    Our named executive officers are entitled to payments and other benefits under their employment agreements in connection with their termination under certain circumstances. We believe that the existence of these potential benefits will discourage turnover and mitigate the influence of a potential change in control on an executive officer'sofficer’s decision-making due to concerns regarding job security. On June 2, 2019, Mr. Tombesi stepped down as our Chief Financial Officer and his employment with the Company ended. Pursuant to a separation agreement, Mr. Tombesi received the following severance benefits: (i) 12 months' salary at his 2019 base salary, paid semi-monthly over a 12-month period; (ii) a pro-rata portion of his annual bonus based on actual Company performance during 2019, payable within two and one-half months following December 31, 2019; (iii) accelerated vesting of any of his options and RSUs that would have otherwise vested within six months of June 2, 2019; and (iv) payment for the cost of COBRA coverage equivalent to his current coverage through no later than May 31, 2020 (minus certain employee contributions), in each case less applicable tax withholding. As of December 31, 2019, Mr. Tombesi had earned $362,237 under this arrangement.

      COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

       

      The Compensation Committee is comprised entirely of independent directors, and none of our executive officers served on the Compensation Committee or on the board of any company that employed any member of our Compensation Committee or our Board during the year ended December 31, 2019.


      DODD-FRANK MANDATED CEO PAY RATIO
      2022.

       

      Dodd-Frank Mandated Pay Ratio Disclosure

      As required by Section 953(b) of the Dodd-Frank Wall Street Reform and Consumer Protection Act, and Item 402(u) of Regulation S-K, we are providing the following information about the relationship of the median annual total compensation of our employees and the annual total compensation of Mr. Lewis, our President and CEO. Registrants may identify the median employee once every three years unless there has been a change in their employee population or employee compensation arrangements that the registrant reasonably believes would result in a significant change in pay ratio disclosure. The pay ratio included in this section is calculated in a manner consistent with Item 402(u) of Regulation S-K.

          In 2019, we determined the median of the annual total compensation of all employees of our company (other than Mr. Lewis) for 2019 was $237,800.

          For 2019, the annual total compensation of Mr. Lewis, as reported in the Summary Compensation Table, is $7,175,094.

       

      In 2022, we determined the median of the annual total compensation of all employees of our company (other than Mr. Lewis) for 2022 was $256,516.

      For 2022, the annual total compensation of Mr. Lewis, as reported in the Summary Compensation Table, is $7,789,898.

      Based on this information, the ratio of the median of the annual total compensation of all employees (other than Mr. Lewis) to the annual total compensation of Mr. Lewis was 1 to 30.17.30.37.

       

      To identify the median of the annual total compensation of all of our employees (other than Mr. Lewis), as well as to determine the annual total compensation of our median employee, we took the following steps:

        1.
        We determined that, as of December 31, 2019, our employee population, excluding Mr. Lewis, consisted of approximately 434 individuals working either at Insmed Incorporated or one of our consolidated subsidiaries. This population consisted of our full-time, part-time and temporary employees and, as permitted by SEC rules, excluded independent contractors or similar non-employee workers during 2019. We did not exclude any non-US employees from these calculations.

        2.
        To identify the "median employee" from our employee population, we compared the sum of each employee's wages, aggregate fair value of equity awards and target cash bonus for 2019. In doing so, we annualized the compensation of all permanent

      Table of Contents

          1.We determined that, as of December 31, 2022, our employee population, excluding Mr. Lewis, consisted of approximately 735 individuals working either at Insmed Incorporated or one of our consolidated subsidiaries. This population consisted of our full-time, part-time, and temporary employees and, as permitted by SEC rules, excluded independent contractors or similar non-employee workers during 2022. We did not exclude any non-US employees from these calculations.

          employees who were hired in 2019

          2.To identify the “median employee” from our employee population, we compared the sum of each employee’s wages, aggregate fair value of equity awards, and target cash bonus for 2022. In doing so, we annualized the salary of all permanent employees who were hired in 2022 but did not work for us the entire fiscal year. The fair value of option awards granted during 2022 was calculated using the Black-Scholes valuation model pursuant to the assumptions described in Note 10, “Stock-Based Compensation” of the consolidated financial statements included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2022. We did not make any cost-of-living adjustments in identifying the median employee.

          3.After identifying the median employee, we calculated annual total compensation for the employee using the same methodology we use for our named executive officers, as set forth in the Summary Compensation Table. This process resulted in a median employee with annual total compensation of $256,516 for 2022.

          The fair value of option awards granted during 2019 was calculated using the Black-Scholes valuation model pursuant to the assumptions described in Note 10, "Stock-Based Compensation" of the consolidated financial statements included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2019. We did not make any cost-of-living adjustments in identifying the median employee.

        3.
        After identifying the median employee, we calculated annual total compensation for the employee using the same methodology we use for our named executive officers, as set forth in the Summary Compensation Table. This process resulted in a median employee with annual total compensation of $237,800 for 2019.

                    The SEC'sSEC’s rules for identifying the median employee and calculating the pay ratio based on that employee'semployee’s annual total compensation allow companies to adopt a variety of methodologies, to apply certain exclusions, and to make reasonable estimates and assumptions that reflect their employee populations and compensation practices. As a result, the pay ratios reported by other companies may not be comparable to our pay ratio, reported above, as other companies have different employee populations and compensation practices and may utilize different methodologies, exclusions, estimates, and assumptions in calculating their own pay ratios.

      Compensation Actually Paid Versus Company Performance

      The following graph visually describes the relationship between “compensation actually paid” to our PEO and the average “compensation actually paid” to our non-PEO NEOs, to the cumulative total shareholder return of Insmed. In addition, it compares the cumulative total shareholder return of Insmed to our selected peer group, the Nasdaq Biotechnology Index.

       


      75INSMED PROXY STATEMENT


      The following graph visually describes the relationship between “compensation actually paid” to our PEO and the average “compensation actually paid” to our non-PEO NEOs, to net income (loss). Insmed does not consider net income (loss) as a relevant measure for determining our executive compensation given the lifecycle stage of our company. The movement in “compensation actually paid” across the three-year time horizon does not move meaningfully or deliberately in relation to the reported net income (loss).

      76INSMED PROXY STATEMENT


      Tabular List of Company Performance Measures

      As further described in our CD&A, we believe that the compensation opportunities for our NEOs should be predominantly variable with a significant portion in the form of short-term and long-term incentives. Given the current life-cycle stage of Insmed, financial measures do not feature meaningfully in our incentive plan design, which instead focuses on pipeline progress across our four pillars and stock price performance. For the fiscal year ending December 31, 2022, the only financial performance measure used to link “compensation actually paid” to our NEOs to company performance was total shareholder return. Total shareholder return will be used on a relative basis to assess performance in respect of the 2022 PSU awards, which currently remain unvested and outstanding, at the conclusion of the performance period. As a result of total shareholder return already being included in the pay versus performance table, no company-selected measure is reported.

      Director Compensation

      Our Board determines the compensation of our non-employee directors based in part on recommendations made by the Compensation Committee. TheBased on data and advice provided by their independent consultant WTW, the Compensation Committee evaluates the form and amount of compensation for non-employee directors at least annually and recommends changes to our Board when appropriate. Our Board is currently compensated through a combination of cash retainers and equity awards in the form of RSUs. Our approach to Board compensation is intended to align our non-employee director compensation practices with the interests of our shareholders. For example,This is achieved through setting compensation levels and practices informed by market median practices, using the same compensation peer group that is considered for our named executive officers. In addition, we have share ownership guidelines in place for our non-employee directors, with a target share ownership of three times the amount of each director'sdirector’s annual retainer that should be achieved within five years after the adoption of the guidelines or first appointment to the Board, whichever is later. As of the Record Date, all of our non-employee directors who had been on the Board for at least five years exceeded the share ownership guidelines. Mr. Lewis is a director and an executive officer of the Company. He receives no additional compensation for serving on the Board. Our share ownership guidelines for Mr. Lewis are described under "Compensation“Compensation Discussion and Analysis—Corporate Governance Perspectives on our Executive Compensation Program"Program” above. No other director is an employee of the Company.

      PROPOSAL NO. 4

      AMENDMENT NO. 1 TOAPPROVAL OF THE INSMED INCORPORATED AMENDED AND RESTATED 2019 INCENTIVE PLAN

      The 2019 Incentive Plan was approved by our shareholders at the 2019 Annual Meeting of Shareholders. The Board of Directors adopted on March 30, 2020, subject to shareholder approval, Amendment No. 1, to the 2019 Incentive Plan (the Amendment) to providewhich provided for the issuance of 4,500,000 additional shares of Common Stock under the 2019 Incentive Plan.Plan, was approved by our shareholders at the 2020 Annual Meeting of Shareholders. The 2019 Incentive Plan was further amended by the Omnibus Amendment to Insmed Incorporated Incentive Plans, dated December 10, 2020, to permit the transfer of certain awards for estate-planning purposes. Amendment No. 2, which provided for the issuance of 2,750,000 additional shares of Common Stock under the 2019 Incentive Plan, was approved by our shareholders at the 2021 Annual Meeting of Shareholders. Amendment No. 3, which provided for the issuance of 3,000,000 additional shares of Common Stock under the 2019 Incentive Plan, among other changes, was approved by our shareholders at the 2022 Annual Meeting. The Board of Directors adopted on March 29, 2023, subject to shareholder approval, the Amended and Restated 2019 Incentive Plan (the “Amended and Restated 2019 Incentive Plan”), which amends and restates the 2019 Incentive Plan to provide for the issuance of 10,500,000 additional shares of Common Stock thereunder. In addition, the Amended and Restated 2019 Incentive Plan also (i) provides that each share of Common Stock subject to a full value award will be counted as 1.45 shares for purposes of calculating the number of shares of Common Stock available for issuance thereunder, (ii) limits the exceptions to the minimum vesting requirement, (iii) clarifies the term of tandem SARs (as defined below), (iv) clarifies the payment timing of dividends and dividend equivalents, and (v) provides the administrator with discretion to cancel awards in exchange for cash and/or other consideration in connection with a change in control. No other changes to the 2019 Incentive Plan are proposed or recommended. The AmendmentAmended and Restated 2019 Incentive Plan is attached hereto as Appendix A.

      Background and Purpose

      If the AmendmentAmended and Restated 2019 Incentive Plan is not approved, we will have remaining only 736,091186,657 shares available for future grant under the 2019 Incentive Plan (plus any shares that might be returned to the 2019 Incentive Plan as a result of future cancellations, terminations, expirations, forfeitures, and lapses), based on awards outstanding as of the Record Date, and thereafter we will have limited ability to grant additional equity incentives under the 2019 Incentive Plan. WeAmong other activities, we continue to focus on the successful commercialization of ARIKAYCE in the US, Europe and Japan for appropriate patients, are seeking regulatory approvalscontinue to advance the post-approval confirmatory, frontline clinical trial program for ARIKAYCE, outsidethrough the US, such as in EuropeARISE trial and Japan,the ENCORE trial, and expectcontinue to design and conduct a Phase 3 program for INS1007 through which we willadvance the ASPEN trial of brensocatib, to seek to confirm the positive results seen in the WILLOW study.trial and to support a new drug application. We expect these activities to result in continued increases in our employee headcount and toheadcount. To ensure that we have sufficient equity plan capacity to compensate and incentivize our employees as we undertake these activities, the Board adopted the AmendmentAmended and Restated 2019 Incentive Plan and strongly recommends that our shareholders approve the Amendment.Amended and Restated 2019 Incentive Plan.

      Equity-based compensation is a vital part of our compensation program for our employees, including our named executive officers, and our non-employee directors. We believe equity-based compensation creates an ownership culture that rewards our executives for maximizing shareholder value over time and aligns the interests of our employees and directors with those of our shareholders. We have traditionally granted stock options to new hires in connection with their commencement of employment and stock options, as well as other forms of equity-based compensation, to key employees as part of their ongoing compensation packages. In 2018, we began granting RSUs to our employees. In 2022, we began granting PSUs to our executive officers and other key employees. We believe that providing these equity awards incentivizes employees, including management, to create long-termlong term shareholder value and aids in retention efforts, as awards generally vest over a number of years. In addition, we grant RSUs to non-employee directors annually as part of their compensation for service on the Board.

      82INSMED PROXY STATEMENT


      The Board currently intends that the 4,500,00010,500,000 shares requested under the Amendment,Amended and Restated 2019 Incentive Plan, in addition to the 736,091186,657 shares available for future grant under the Amended and Restated 2019 Incentive Plan (plus any shares that might be returned to the Amended and Restated 2019 Incentive Plan as a result of future cancellations, terminations, expirations, forfeitures and lapses), will be sufficient to fund the Company'sCompany’s annual stock option and RSU grants to current employees, PSU grants to our executive officers and other current key employees, as well as equity grants to new hires for at least the next year,up to two years, which it believes appropriate taking into account the Company'sCompany’s planned growth. Upon a review of the remaining shares available for grant under our 2019 Incentive Plan and the anticipated need for future equity award issuances, the Board approved the AmendmentAmended and Restated 2019 Incentive Plan and the share pool authorized for issuance thereunder to ensure that we have sufficient equity plan capacity to continue to provide our eligible employees and directors with appropriate equity-based incentives.


      Table

      In addition, the Amended and Restated 2019 Incentive Plan also provides that (i) each share of ContentsCommon Stock subject to a full value award granted thereunder will reduce the number of shares of Common Stock available for issuance by 1.45 shares, and that each share of Common Stock subject to a full value award that is added back to the Amended and Restated 2019 Incentive Plan in accordance with the terms thereof will count towards such number as 1.45 shares, (ii) awards granted under the Amended and Restated 2019 Incentive Plan are subject to a minimum vesting period of one year, except in the case of substitute awards issued in connection with acquisitions, awards that vest in connection with the participant’s death or disability, or awards granted pursuant to the 5% share pool exception described in further detail below, (iii) tandem SARs shall have the same term (including any extension thereof) as the stock option to which they relate, (iv) no dividends or dividend equivalents will be paid in either cash or shares (other than shares subject to the same restrictions as the associated restricted stock) prior to the vesting of the portion of the award to which such dividends or dividend equivalents relate. We believe that these changes reflect best compensation governance practices in furtherance of shareholder interests, and (v) in the event of a change in control, the administrator may in its discretion provide that outstanding awards will be cancelled in exchange for cash and/or other consideration based on the fair market value of a share of Common Stock on the date of such change in control. 

      Key Considerations for Requesting Additional Shares

      In determining the number of shares to be authorized under the Amended and Restated 2019 Incentive Plan, as proposed to be amended, the Board considered the following principal factors:

          Number of Shares Available for Grant under Existing Plan:  As of the Record Date, 736,091 shares remained available for issuance under the 2019 Incentive Plan. There were no shares available to grant under prior incentive plans.

          Number of Outstanding Awards Under All Plans:  As of the Record Date, there were 13,155,696 outstanding stock options, which had a weighted average exercise price of $17.96 and a weighted average remaining contractual life of 7.30 years, and there were 931,384 RSU awards outstanding.

          Burn Rate:  Burn rate measures our usage of shares for our stock plans as a percentage of our outstanding shares. For 2019, 2018, and 2017, our burn rate was 3.42%, 1.95%, and 2.88%, respectively, resulting in an average annual burn rate of 2.75% over a three-year period. The rates were calculated by dividing the number of shares subject to awards granted during the year net of forfeitures and cancellations by the weighted average number of shares outstanding during the year.

      Number of Shares Available for Grant under Existing Plan: As of the Record Date, 186,657 shares remained available for issuance under the 2019 Incentive Plan. There were no shares available to grant under prior incentive plans.

      Number of Outstanding Awards Under All Plans: As of the Record Date, there were 19,216,126 outstanding stock options, which had a weighted average exercise price of $21.75 and a weighted average remaining contractual life of 7.13 years, there were 2,062,463 RSU awards outstanding, and there were 268,445 PSU awards outstanding at the target level.

      Burn Rate: Burn rate measures our usage of shares for our stock plans as a percentage of our outstanding shares. For 2022, 2021, and 2020, our burn rate was 4.47%, 3.15%, and 4.05%, respectively, resulting in an average annual burn rate of 3.89% over a three-year period. The rates were calculated by dividing the number of shares subject to awards granted during the year net of forfeitures and cancellations by the weighted average number of shares outstanding during the year.

      New Plan Benefits

      Awards under the Amended and Restated 2019 Incentive Plan as proposed to be amended, are discretionary and the administrator has not yet determined to whom future awards will be made and the terms and conditions of such awards.

      Administration

      Administration.

      The Amended and Restated 2019 Incentive Plan is administered by the Compensation Committee, or, in the absence of the Compensation Committee, the Board itself. Any power of the administrator may also be exercised by the Board. To the extent that any permitted action taken by the Board conflicts with action taken by the administrator, the Board action will control. The Compensation Committee may by resolution authorize one or more officers of the Company to perform any or all things that the administrator is authorized and empowered to do or perform under the Amended and Restated 2019 Incentive Plan; provided, however, that such authorization must specify the total number of awards (if any) such officer or officers may award pursuant to such delegated authority, and provided further that in no event may an officer of the Company be delegated the authority to grant awards to, or amend awards held by, the individuals who are subject to Section 16 of the Exchange Act or report directly to such officer. Additionally, no such officer may grant any awards to himself or herself. The administrator may also delegate any or all aspects of the day-to-day administration of the Amended and Restated 2019 Incentive Plan to one or more officers or employees of the Company or any subsidiary, and/or to one or more agents.

      85INSMED PROXY STATEMENT


      Subject to the provisions of the Amended and Restated 2019 Incentive Plan, the administrator has the authority to select the participants to receive awards and to grant such awards and to determine the terms and conditions of awards and the number of shares to be issued pursuant thereto, including conditioning the receipt or vesting of awards upon achievement of performance conditions.All decisions, determinations and interpretations by the administrator are final and binding on all participants and all other persons holding or claiming rights under the plan or any award granted thereunder.

      Awards

      Awards.

      The Amended and Restated 2019 Incentive Plan authorizes the grant of awards of stock options, SARs, restricted stock, and RSUs. Any award may be subject to performance conditions as determined by the administrator. The terms of awards will be determined by the administrator and set forth in an award agreement. The terms of any awards may vary among participants. Subject to the provisions of the Amended and Restated 2019 Incentive Plan, the administrator will specify before, at or after the time of grant the provisions governing the effects upon an award of a separation from service or other termination of service. Unless otherwise provided in an award agreement or another agreement, including an employment agreement, unvested awards will be forfeited immediately if a participant terminates his or her employment with the Company for any reason. Participants will not have any rights as a shareholder with respect to shares covered by an award until the date the participant becomes the holder of record of such shares. Awards granted under the plan are subject to a minimum vesting period of one year, except in the case of substitute awards issued in connection with acquisitions or awards that vest in connection with certain acceleration events.the participant’s death or disability. Additionally, the administrator has the authority to grant awards covering up to 5% of the plan'splan’s share pool that are not subject to this minimum vesting requirement. With respect to awards that entitle a participant to dividends or dividend equivalents, in no event may such dividends or dividend equivalents, if any, be paid to the participant prior to the vesting of the portion of the award to which such dividends or dividend equivalents relate.


      Table The administrator may not accelerate the vesting or exercisability of Contentsall or any portion of an award following the grant date of such award unless (i) explicitly provided under the terms of an award agreement (subject to the minimum vesting requirement), (ii) explicitly provided under the terms of an employment or service agreement, or (iii) in connection with a change in control or a grantee’s death or disability.

      Stock Options.Stock options granted under the Amended and Restated 2019 Incentive Plan may be either non-qualified stock options or ISOs under Section 422 of the Code. The exercise price of any stock option granted, other than substitute awards, may not be less than 100% of the fair market value of a share of our Common Stock on the date of grant (provided that the exercise price of an ISO granted to a participant who owns stock possessing more than 10 percent of the combined voting power of all classes of the Company'sCompany’s stock (a 10% Shareholder)“10% Shareholder”) will be at least 110% of the fair market value on such date). The option exercise price is payable in cash or such other method as determined by the administrator, including an irrevocable commitment by a broker to pay over such amount from a sale of the shares issuable under an option, the delivery of previously owned shares of Common Stock or withholding of shares of Common Stock deliverable upon exercise. Vesting may be based on continued employment, passage of time, attainment of age and/or service requirements, and/or satisfaction of performance conditions. The term of a stock option will in no event be greater than ten years (or, for an ISO granted to a 10% Shareholder, five years), provided that the term of a non-qualified stock option will be automatically extended if, at the time of its scheduled expiration, the participant holding such option is prohibited by law or by the Company'sCompany’s insider trading policy from exercising such option. Any such extension will expire on the 30th30th day following the date such prohibition no longer applies.

      Other than in connection with a change in the Company'sCompany’s capitalization, at any time when the exercise price of an option is above the fair market value of a share of Common Stock, the Company may not, without shareholder approval: (i) reduce the exercise price of such option, (ii) exchange such option for cash, another award, or a new option or SAR with a lower exercise price, or (iii) otherwise reprice such option. Options may not be granted under the Amended and Restated 2019 Incentive Plan in consideration for, and will not be conditioned upon the delivery of shares to the Company in payment of the exercise price and/or tax withholding obligation under, any other option. Holders of a stock option will have no voting rights or rights to receive dividends or dividend equivalents with respect to their stock option until they become the holder of record of the underlying shares.

      As of the Record Date, the fair market value of a share of our Common Stock, determined by the last reported sale price per share on that date as quoted on the Nasdaq Global Select Market, was $14.39.$18.32.

      Restricted Stock and Restricted Stock Units.Units. The grant, issuance, retention, vesting, and/or settlement of any restricted stock or RSU award will occur at such time and be subject to such terms and conditions as determined by the administrator or under conditions established by the administrator, which may include conditions based on continued employment, passage of time, attainment of age and/or service requirements, and/or satisfaction of performance conditions. Participants who receive restricted stock will be entitled to receive all dividends and other distributions paid with respect to those shares unless determined otherwise by the administrator.

      The administrator will determine whether such dividends or distributions will be automatically reinvested in additional restricted stock and/or subject to the same restrictions as the underlying restricted stock, or whether such dividends or distributions will be paid in cash. Unless otherwise set forth in the award agreement, prior to the time shares are issued to a participant under an RSU, the Company will pay or accrue dividend equivalents on each date that dividends are paid, and such dividend equivalents will be paid at the time specified in the award agreement. As described above, no dividends or dividend equivalents may be paid in cash or shares (other than shares subject to the same restrictions as the associated restricted stock) with respect to an award of restricted stock or RSUs prior to the vesting of the portion of the award to which such dividends or dividend equivalents relate. Unless otherwise determined by the administrator, participants holding shares of restricted stock may exercise full voting rights with respect to those shares during the period of restriction. Participants holding RSUs will not have voting rights with respect to the underlying shares until they become the holder of record of the underlying shares.

      Stock Appreciation Rights.Rights. A SAR entitles the participant, upon settlement, to receive a payment based on the excess of the aggregate market price of a specified number of shares of Common Stock at the time of the exercise over the exercise price of the right. SARs may be granted on a stand-alone basis or in tandem with a related stock option. The exercise price may not be less than the fair market value of a share of our Common Stock on the date of grant. A SAR granted in tandem with a stock option will have an exercise price equal to the exercise price of the stock option to which it relates, as well as the same term (including any extensions thereof) of the stock option to which it relates. The administrator will determine the vesting requirements and the payment and other terms of a SAR, including the effect of termination of service of a participant. Vesting may be based on continued employment, passage of time, attainment of age and/or service requirements, and/or satisfaction of performance conditions. Other than in connection with a change in the Company'sCompany’s capitalization, at any time when the exercise price of a SAR is above the fair market value of a share of Common Stock, the Company may not, without shareholder approval: (i) reduce the exercise price of such SAR, (ii) exchange such SAR for cash, another award, or a new option or SAR with a lower exercise price, or (iii) otherwise reprice such SAR. Holders of a SAR will have no voting rights or rights to receive dividends or dividend equivalents with respect to their SAR until they become the holder of record of the underlying shares.

      Adjustment and Change in ControlControl.

      The number and kind of shares of Common Stock available for issuance (including under any awards then outstanding), and the number and kind of shares of Common Stock subject to the limits set forth in the Amended and Restated 2019 Incentive Plan, will be equitably adjusted by the administrator to reflect any reorganization, reclassification, combination of shares, stock split, reverse stock split, spin-off, dividend or distribution of securities, property or cash (other than regular, quarterly cash dividends), or any other event or transaction that affects the number or kind of shares of Common Stock outstanding. Such adjustment may be designed to comply with Section 424 of the Code or may be designed to treat the shares available under the Amended and Restated 2019 Incentive Plan and subject to awards as if they were all outstanding on the record date for such event or transaction or to increase the number of such shares to reflect a deemed reinvestment in shares of the amount distributed to the Company'sCompany’s security holders. The terms of any outstanding award will also be equitably adjusted by the administrator as to price, number or kind of shares subject to such award, vesting, and other terms to reflect the foregoing events, which adjustments need not be uniform as between different awards or different types of awards. No fractional shares of Common Stock will be issued pursuant to such an adjustment. In the event there is any other change in the number or kind of outstanding shares of Common Stock, or any stock or other securities into which such Common Stock will have been changed, or for which it will have been exchanged, by reason of a change in control, other merger, consolidation or otherwise, then the administrator will determine the appropriate and equitable adjustment to be effected, which adjustments need not be uniform between different awards or different types of awards. In addition, in the event of such change, the administrator may accelerate the time or times at which any award may be exercised, consistent with and as otherwise permitted under Section 409A of the Code, and may provide for cancellation of such accelerated awards that are not exercised within a time prescribed by the administrator in its sole discretion.

      Unless otherwise expressly provided for in an award agreement or another agreement, including an employment agreement, in the event of a change in control, unless provision is made in connection with the change in control for (i) assumption of awards previously granted or (ii) substitution for such awards, or unless the administrator exercises the discretion to cancel outstanding awards in exchange for cash and/or other consideration as described further below, (A) the administrator will make an adjustment to any or all awards as the administrator deems appropriate to reflect such change in control or (B) (1) in the case of an option or SAR, the participant will have the ability to exercise such option or SAR, including any portion of the option or SAR not previously exercisable, and the unexercised portion of such option or SAR will be cancelled upon on the consummation of the change in control; (2) in the case of an award


      Table of Contents

      subject to performance conditions, the participant will have the right to receive a payment based on performance through a date determined by the administrator prior to the change in control (unless such performance cannot be determined, in which case the participant will have the right to receive a payment equal to the target amount payable); and (3) in the case of outstanding restricted stock and/or RSUs not subject to performance conditions, all conditions to the grant, issuance, retention, vesting, or transferability of, or any other restrictions applicable to, such award will immediately lapse. The administrator is not required to treat all participants, all awards, all awards held by a participant, all portions of a single award, or all awards of the same type identically.

       

      In the event of a change in control, the administrator may in its discretion provide that outstanding awards, whether vested or unvested, will be cancelled in exchange for cash and/or other consideration with a value equal to (i) for awards other than options or SARs, the fair market value of the shares of Common Stock underlying such award on the date of such change in control or (ii) for options or SARs, the excess, if any, of the fair market value of the shares of Common Stock underlying such award on the date of such change in control over the aggregate exercise price. However, if the fair market value of a share of Common Stock on such date does not exceed the per share exercise price of the option or SAR, the administrator may cancel the option or SAR for no consideration.

      Unless otherwise expressly provided for in an award agreement or another agreement, including an employment agreement, or under the terms of a transaction constituting a change in control, the following will occur upon a participant'sparticipant’s involuntary termination of employment or other service within 24 months following a change in control, provided that such termination does not result from disability, cause, or gross misconduct: (i) in the case of an option or SAR, the participant will have the ability to exercise such option or SAR, including any portion of the option or SAR not previously exercisable, and the option or SAR will remain exercisable for a period of three years following such termination (or until expiration, if earlier), (ii) in the case of an award subject to performance conditions, the participant will have the right to receive a payment based on performance through a date determined by the administrator prior to the change in control (unless such performance cannot be determined, in which case the participant will have the right to receive a payment equal to the target amount payable), and (iii) in the case of outstanding restricted stock and/or RSUs not subject to performance conditions, all conditions to the grant, issuance, retention, vesting, or transferability of, or any other restrictions applicable to, such award will immediately lapse.

      FEDERAL INCOME TAX TREATMENT

       Federal Income Tax Treatment

      The following discussion summarizes the material U.S. federal income tax consequences to the Company and the participants in connection with the Amended and Restated 2019 Incentive Plan under existing applicable provisions of the Code and the accompanying regulations. The discussion is general in nature and does not address issues relating to the income tax circumstances of any individual participant. The discussion is based on federal income tax laws in effect on the date of this Proxy Statement and is, therefore, subject to possible future changes in the law. The discussion does not address the consequences of state, local, or foreign tax laws.

      Nonqualified OptionsOptions.

      An employee will not recognize any income upon receipt of a nonqualified stock option, and the Company will not be entitled to a deduction for federal income tax purposes at the time of grant. Ordinary income will be realized by the holder at the time the nonqualified stock option is exercised and the shares are transferred to the employee. The amount of such taxable income, in the case of a nonqualified stock option, will be the excess, if any, of the fair market value of the shares on the date of exercise over the exercise price. The Company will generally be entitled to a tax deduction in an amount equal to the ordinary income that an employee recognizes upon exercise.

      Incentive Stock OptionsOptions.

      An employee who receives an ISO will not recognize any income for federal income tax purposes upon receipt of the ISO, and the Company will not realize a deduction for federal income tax purposes. The holder generally will not be taxed upon exercise, but the excess, if any, of the fair market value of the stock on the date of exercise over the option exercise price may subject the holder to the alternative minimum tax. If the holder does not dispose of the ISO shares within two years from the date the option was granted or within one year after the shares were transferred to him on exercise of the option, then that portion of the gain on the sale of the shares that


      Table of Contents

      is equal to the difference between the sales price and the option exercise price will be treated as a long-term capital gain. The Company will not be entitled to a deduction either at the time the employee exercises the ISO or subsequently sells the ISO shares. However, if the employee sells the ISO shares within two years after the date the ISO is granted or within one year after the date the ISO is exercised, then the sale is considered a disqualifying sale, and the spread on exercise will be taxed as ordinary income. The balance of the gain will be treated as long- or short-term capital gain depending on the length of time the employee held the stock. If the shares decline in value after the date of exercise, the compensation income will be limited to the difference between the sale price and the amount paid for the shares. The tax will be imposed in the year the disqualifying sale is made. The Company will be entitled to a deduction equal to the ordinary income recognized by the employee.

      With respect to both nonqualified stock options and ISOs, special rules apply if an employee uses shares already held by the employee to pay the exercise price or if the shares received upon exercise of the option are subject to a substantial risk of forfeiture by the employee.

      Restricted StockStock.

       .

      Employees receiving restricted stock will not recognize any income upon receipt of the restricted stock. Ordinary income will be realized by the holder at the time that the restrictions on transfer are removed or expire. The amount of ordinary income will be equal to the fair market value of the shares on the date that the restrictions on transfer are removed or expire. The Company will be entitled to a deduction at the same time and in the same amount as the ordinary income the employee is deemed to have realized. However, no later than 30 days after an employee receives the restricted stock, the employee may elect to recognize taxable ordinary income in an amount equal to the fair market value of the shares at the time of receipt. Provided that the election is made in a timely manner, when the restrictions on the shares lapse, the employee will not recognize any additional income. If the employee forfeits the shares to the Company, the employee may not claim a deduction with respect to the income recognized as a result of the election.

      91INSMED PROXY STATEMENT


      Generally, when an employee disposes of shares acquired under the Amended and Restated 2019 Incentive Plan, the difference between the sales price and his or her basis in such shares will be treated as long- or short-term capital gain or loss depending upon the holding period for the shares.

      Restricted Stock UnitsUnits.

      Employees who are granted RSUs do not recognize income at the time of the grant. When the award vests or is paid, participants recognize ordinary income in an amount equal to the fair market value of the units at such time, and the Company will receive a corresponding tax deduction.

      Stock Appreciation RightsRights.

      Upon exercise of a SAR, an employee will recognize taxable income in the amount of the cash received. An employee who receives unrestricted shares upon exercise of a SAR will recognize ordinary income in the year of exercise equal to the fair market value of the shares received. In either such case, the Company will be entitled to an income tax deduction in the amount of such income recognized by the employee.

      Potential Limitation on DeductionsDeductions.

      Section 162(m) of the Code places a limit of $1,000,000 on the amount the Company may deduct in any one year for compensation paid to each of the Company's "coveredCompany’s “covered employees." The definition of "covered employee"“covered employee” includes anyone who was the Company'sCompany’s CEO or CFO at any time during the year, as well as the Company'sCompany’s three other most highly-compensated executive officers during the year. Anyyear, and any such individual who is or became a covered employee after December 31, 2016 will always be treated as a covered employee, even after termination of employment. For taxable years beginning after December 31, 2026, the definition of “covered employee” will also include the employees who are among the five highest compensated employees for the applicable taxable year other than the Company’s CEO, CFO, or three other most highly-compensated executive officers for such year. Accordingly, awards granted to the Company'sCompany’s covered employees under the Amended and Restated 2019 Incentive Plan may not be fully deductible.

      Federal Income Tax Consequences to the CompanyCompany.

      To the extent that a recipient recognizes ordinary income in the circumstances described above, the Company will be entitled to a corresponding deduction provided that, among other things, the income meets the test of reasonableness, is an ordinary and necessary business expense, is not an "excess“excess parachute payment"payment” within the meaning of Section 280G of the Code and is not disallowed by the $1,000,000 limitation on certain executive compensation under Section 162(m). of the Code.

      General Information about the

      Annual Meeting and Voting

      DISTRIBUTION OF PROXY SOLICITATION AND OTHER REQUIRED ANNUAL MEETING MATERIALS

      The Board of Directors (the “Board”) of Insmed Incorporated is soliciting your proxy for the 2023 Annual Meeting of Shareholders (the “Annual Meeting”) on May 11, 2023, at 9:00 a.m. Eastern Time, and any adjournment or postponement thereof. The Annual Meeting will be held virtually via the Internet at www.virtualshareholdermeeting.com/INSM2023. We intend to make the Proxy Statement and related proxy materials available to our shareholders on or about March 31, 2023.

      Information about the Annual Meeting and Voting at or Prior to the Annual Meeting

      Why Did I Receive a One-page Notice in the Mail Regarding the Internet Availability of Proxy Materials Instead of a Full Set of Proxy Materials?

      Pursuant to rules adopted by the Securities and Exchange Commission (the “SEC”), we have elected to mail to many of our shareholders a Notice of Internet Availability of the Proxy Materials (the “Notice”) instead of a paper copy of the proxy materials. All shareholders receiving the Notice will have the ability to access the proxy materials over the Internet and receive a paper copy of the proxy materials by mail on request. Instructions on how to access the proxy materials over the Internet or to request a paper copy may be found in the Notice. In addition, the Notice contains instructions on how you may request proxy materials in printed form by mail or electronically on an ongoing basis. This process has allowed us to expedite our shareholders’ receipt of proxy materials, lower the costs of distribution and reduce the environmental impact of our Annual Meeting.

      Who May Vote Shares in Connection with the Annual Meeting?

      Shareholders of record at the close of business on March 14, 2023 (the “Record Date”), will be entitled to notice of and to vote at the Annual Meeting. As of the Record Date, we had 136,428,466 outstanding shares of our common stock, $0.01 par value per share (the “Common Stock”). Each share of our Common Stock entitles the holder to one vote with respect to all matters submitted to shareholders at the Annual Meeting. Beneficial owners of shares of our Common Stock may direct the record holder of the shares on how to vote the shares held on their behalf.

      Who May Participate in the Annual Meeting?

      This year’s Annual Meeting will take place virtually through the Internet. We have designed the format of this year’s Annual Meeting to ensure that our shareholders who attend the Annual Meeting will be afforded the same rights and opportunities to participate as they would at an in-person meeting. You are entitled to attend and participate in the Annual Meeting only if you were a shareholder of record as of the close of business on the Record Date, or if you hold a valid proxy for the meeting, as described below. To be admitted to the Annual Meeting at www.virtualshareholdermeeting.com/INSM2023, you must enter the 16-digit control number found on your Notice, proxy card, or other proxy materials. If you do not have a control number, please contact the brokerage firm, bank, dealer, or other similar organization that holds your account as soon as possible so that you can be provided with a control number.

      97INSMED PROXY STATEMENT


      What is a Shareholder of Record and How Can I Vote if I am a Shareholder of Record?

      If, as of the close of business on the Record Date, shares of our Common Stock were registered directly in your name with our transfer agent, then you are a shareholder of record. As a shareholder of record, you may vote by proxy in advance or at the Annual Meeting.

      If you are a shareholder of record, you may vote or submit a proxy as follows:

      1.By Internet

      Before the Annual Meeting—You may authorize the voting of your shares by following the “Vote by Internet” instructions set forth on the Notice or proxy card through 11:59 p.m. Eastern Time on Wednesday, May 10, 2023. You must specify how you want your shares voted or your vote will not be completed and you will receive an error message.

      During the Annual Meeting—You may vote online during the Annual Meeting. You may cast your vote electronically during the Annual Meeting using the 16-digit control number found on your Notice or proxy card or other proxy materials and following the instructions at www.virtualshareholdermeeting.com/INSM2023.

      2.By Telephone—Dial 1-800-690-6903 using any touch-tone phone to transmit your voting instructions through 11:59 p.m. Eastern Time on Wednesday, May 10, 2023. Have your Notice, proxy card, or other proxy materials in hand when you call and follow the voting instructions given to you over the phone.

      3.By Mail—Complete and sign the proxy card and mail it in accordance with the instructions on the proxy card. Completed proxy cards must be received by 11:59 p.m. Eastern Time on Wednesday, May 10, 2023.

      In all cases, your shares will be voted according to your instructions.

      What is a Beneficial Owner of Shares and How Can I Vote if I am a Beneficial Owner?

      If, on the Record Date, your shares of our Common Stock were not held in your name with our transfer agent, but instead were held in an account at a brokerage firm, bank, dealer, or other similar organization, then you are the beneficial owner of shares held in “street name,” and these proxy materials have been forwarded to you by that organization. The organization holding your account is considered to be the shareholder of record of shares of our Common Stock for purposes of voting at the Annual Meeting and is required to vote those shares in accordance with your instructions. If you do not give instructions to the organization holding your account, then the organization will have discretion to vote the shares with respect to “routine” matters but will not be permitted to vote the shares with respect to “non-routine” matters. See “What Matters at the Annual Meeting are ‘Routine’ and ‘Non-Routine’?” below. As a beneficial owner, you are invited to attend the Annual Meeting via the Internet at www.virtualshareholdermeeting.com/INSM2023. You may not vote your shares at the Annual Meeting unless you enter the 16-digit control number found on your Notice, proxy card, or other proxy materials.

      What if I Need Technical Assistance During the Annual Meeting?

      We encourage you to access the Annual Meeting before it begins. Online check-in will start shortly before the meeting on May 11, 2023. 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 Annual Meeting log-in page.

      98INSMED PROXY STATEMENT


      What is the Quorum Requirement?

      A quorum of shareholders is necessary to hold the Annual Meeting. Shares of our Common Stock representing a majority of the votes entitled to be cast on a matter at the Annual Meeting (or 136,428,466 shares as of the Record Date) will constitute a quorum for the transaction of business with respect to such matter, unless otherwise provided by law or in our Articles of Incorporation, as amended (the “Articles of Incorporation”). Votes withheld, abstentions and broker non-votes count as present for establishing a quorum.

      What Matters at the Annual Meeting are “Routine” and “Non-Routine”?

      Proposal 1, the election of Class II directors, Proposal 2, the advisory vote on the 2022 compensation of our named executive officers, Proposal 3, the advisory vote on the frequency of future advisory votes on the compensation of our named executive officers, and Proposal 5, the approval of the Insmed Incorporated Amended and Restated 2019 Incentive Plan (the “Amended and Restated 2019 Incentive Plan”), are non-routine matters. Proposal 4, the ratification of the appointment of our independent registered public accounting firm, is a routine matter. If you are a beneficial owner of shares of our Common Stock and do not instruct your broker or other agent how to vote, your shares will not be voted on “non-routine” matters and your shares will be “broker non-votes” with respect to those proposals.

      What are the Voting Requirements to Approve Each Proposal to be Submitted to Shareholders?

      The vote required to elect directors and approve each of the matters scheduled for a vote at the Annual Meeting is set forth below:

      PROPOSALVOTE
      REQUIRED
      BOARD
      RECOMMENDATION
      1.Election of three Class II directorsPlurality of votes castFOR
      2.Advisory vote to approve the 2022 compensation of our named executive officersMajority of votes castFOR
      3.

      Advisory vote on the frequency of future shareholder advisory votes on the compensation of our named executive officers

      Option receiving the highest number of votesEVERY YEAR
      4.Ratification of appointment of Ernst & Young LLP (“Ernst & Young”) as our independent registered public accounting firm for the year ending December 31, 2023Majority of votes castFOR
      5.Approval of the Amended and Restated 2019 Incentive PlanMajority of votes castFOR

      99INSMED PROXY STATEMENT


      Proposal 1, the election of Class II directors, requires a plurality of the votes cast. This means that the three nominees who receive the highest number of affirmative votes cast will be elected irrespective of how small the number of affirmative votes is in comparison to the total number of shares voted. Our Board, however, has adopted a director resignation policy, under which a director nominee in an uncontested election must submit his or her resignation for consideration by our Nominations and Governance Committee of the Board (the “Nominations and Governance Committee”) and our Board if the number of votes withheld with respect to such director’s election exceeds the number of votes “for” such director’s election. See “Corporate Governance—Corporate Governance Matters—Director Resignation Policy” for additional information.

      Proposals 2 and 3, the advisory votes on the 2022 compensation of our named executive officers and the frequency of future advisory votes on the same, are not binding on, nor do they overrule, any decisions of the Company, the Board or the Compensation Committee of the Board (the “Compensation Committee”). We value the input of our shareholders, and in the event that Proposal 2 is not approved by a majority of votes cast, and/ or more votes are cast on Proposal 3 for a different frequency than that recommended by the Board, the Board and the Compensation Committee will consider the votes in future decisions on the compensation of our named executive officers and the frequency of future advisory votes on the compensation of our named executive officers.

      Proposal 4, the ratification of the appointment of Ernst & Young as our independent registered public accounting firm for the year ending December 31, 2023, does not require shareholder ratification under Virginia law, our Articles of Incorporation, or our Amended and Restated Bylaws (the “Bylaws”). However, the Board is submitting the appointment of Ernst & Young to the shareholders for ratification as a matter of good corporate governance. In the event that Proposal 4 is not approved by a majority of votes cast, the Audit Committee will consider the vote in future independent auditor selection decisions.

      Proposal 5, the approval of the Amended and Restated 2019 Incentive Plan, requires the affirmative vote of a majority of the votes cast.

      What Is the Effect of Votes Withheld, Abstentions and Broker Non-Votes On Each of the Proposals?

      Votes that are withheld or any abstentions from voting will not be counted in determining the number of votes cast with respect to any of the proposals. As explained above, because Proposals 1, 2, 3, and 5 are considered “non-routine,” if a beneficial owner does not instruct its broker or other agent how to vote such beneficial owner’s shares, broker non-votes will result. Broker non-votes will not be counted in determining the number of votes cast with respect to these proposals. Because Proposal 4 is considered “routine,” a beneficial owner’s broker or other agent will have discretion to vote any shares with respect to which such beneficial owner does not provide instructions, and no broker non-votes will occur with respect to this proposal.

      What if I Submit a Proxy But Do Not Specify How I Would Like to Vote?

      If we receive a signed and dated proxy card or receive your instructions by Internet or by telephone and your instructions do not specify how your shares are to be voted, your shares will be voted as follows:

      FOR the election of each of the three Class II nominees for director;

      FOR the approval of the 2022 compensation of our named executive officers;

      FOR an advisory vote EVERY YEAR on the compensation of our named executive officers;

      FOR the ratification of the appointment of Ernst & Young as our independent registered public accounting firm for the year ending December 31, 2023; and

      FOR the approval of the Amended and Restated 2019 Incentive Plan.

      Unsigned proxy cards will not be voted.

      100INSMED PROXY STATEMENT


      What If Other Matters Not Described Herein Are Brought Before the Annual Meeting for Action by the Shareholders?

      As of the date of this Proxy Statement, the Board does not intend to present any matters other than those described herein at the Annual Meeting and is not aware of any matters to be presented by other parties. If other matters are properly brought before the Annual Meeting, or any adjournment or postponement thereof, for action by the shareholders, proxies will be voted in accordance with the recommendation of the Board or, in the absence of such a recommendation, in accordance with the judgment of the proxy holders.

      How Can I Revoke a Proxy Once I Have Voted?

      Anyone giving a proxy may revoke it at any time before it is exercised by voting at the Annual Meeting or by delivering, including by phone or Internet, a later dated proxy or written notice of revocation to our Corporate Secretary. Attendance at the Annual Meeting will not itself revoke a proxy. A proxy, if executed, properly delivered and not revoked, will be voted at the Annual Meeting.

      What is the Expected Cost of Soliciting Proxies and Who Will Pay for this Cost?

      We will pay the cost of soliciting proxies. In addition to the use of mail and e-mail, proxies may be solicited in person or by telephone by our employees, with no additional remuneration. We have engaged Morrow Sodali LLC to assist in the solicitation of proxies and provide related advice and informational support, for a service fee, plus customary disbursements, which are not expected to exceed $10,000 in total.

      4. Effective Date and Termination of Plan

      The Insmed Incorporated 2019 Incentive Plan was adopted by the Board on April 3, 2019 (the “Approval Date”), and it became effective when it was approved by the Company’s shareholders on May 16, 2019 (the “Effective Date”). The Plan was adopted by the Board on March 29, 2023 and it will become effective when it is approved by the Company’s shareholders. The Plan shall remain available for the grant of Awards until the tenth (10th) anniversary of the Approval Date. Notwithstanding the foregoing, the Plan may be terminated at such earlier time as the Board may determine. Termination of the Plan will not affect the rights and obligations of the Participants and the Company arising under Awards theretofore granted.

      5. Shares Subject to the Plan and to Awards

      a.Aggregate Limits. The aggregate number of shares of Common Stock issuable under the Plan (the “Share Pool”) shall be equal to the sum of 24,250,000 shares of Common Stock plus any shares of Common Stock subject to outstanding awards under the Prior Plans as of the Effective Date that, after the Effective Date, are canceled, terminate unearned, expire, are forfeited, lapse for any reason, or are settled in cash without the delivery of shares. On the grant date of an Award, the Share Pool shall be reduced either by 1 share of Common Stock for each share subject to an Award other than a Full-Value Award or by 1.45 shares of Common Stock for each share subject to a Full-Value Award. The aggregate number of shares of Common Stock available for grant under the Plan and the number of shares of Common Stock subject to Awards outstanding shall be subject to adjustment as provided in Section 14 of the Plan. The shares of Common Stock issued pursuant to Awards granted under the Plan may be shares that are authorized and unissued or shares that were reacquired by the Company, including shares purchased in the open market.

      b.Issuance of Shares. The Share Pool shall be increased when and to the extent that an Award (or an award under any Prior Plan that is outstanding as of the Effective Date) is canceled, terminates unearned, expires, is forfeited, or lapses for any reason, or an Award (or an award under any Prior Plan that is outstanding as of the Effective Date) is settled in cash without the delivery of shares to the Participant, such that any shares of Common Stock subject to such Award (or such award under any Prior Plan that is outstanding as of the Effective Date) shall again be available for the grant of an Award pursuant to the Plan. Notwithstanding anything to the contrary contained herein, shares subject to an Award (or an award under any Prior Plan that is outstanding as of the Effective Date) shall not again be made available for issuance or delivery under the Plan if such shares are (a) shares tendered in payment of an Option, (b) shares delivered or withheld by the Company to satisfy any tax withholding obligation, or (c) shares covered by a stock-settled Stock Appreciation Right that were not issued upon full settlement. The payment of Dividend Equivalents in cash in conjunction with any outstanding Awards shall not be counted against the shares available for issuance under the Plan. Any shares of Common Stock with respect to Awards issued under the Plan (or awards issued under a Prior Plan) that again become available for future grants pursuant to this Section 5 shall be added back to the Share Pool as 1 share for each share subject to an Award other than a Full-Value Award or as 1.45 shares for each share subject to a Full-Value Award, and, for purposes of this sentence, awards issued under a Prior Plan shall be (i) considered Full-Value Awards if they would have been Full-Value Awards if issued under this Plan and (ii) added back to the Share Pool as 1 share in all other cases.

      c.Tax Code Limit. The aggregate number of shares of Common Stock that may be issued pursuant to the exercise of Incentive Stock Options granted under the Plan shall not exceed 24,250,000 (subject to adjustment pursuant to Section 14 of the Plan).

      A-5       INSMED PROXY STATEMENT


      d.Substitute Awards. Substitute Awards shall not reduce the shares of Common Stock authorized for issuance under the Plan or authorized for grant to a Participant in any calendar year. Additionally, in the event that a company acquired by the Company or any Subsidiary, or with which the Company or any Subsidiary combines, has shares available under a pre-existing plan approved by such acquired company’s shareholders and not adopted in contemplation of such acquisition or combination, the shares available for grant pursuant to the terms of such pre-existing plan (as adjusted, to the extent appropriate, using the exchange ratio or other adjustment or valuation ratio or formula used in such acquisition or combination to determine the consideration payable to the holders of common stock of the entities party to such acquisition or combination) may be used for Awards under the Plan and shall not reduce the shares of Common Stock authorized for issuance under the Plan; provided that Awards using such available shares shall not be made after the last day awards or grants could have been made under the terms of the pre-existing plan, absent the acquisition or combination, and shall not be granted to individuals who were employed by the Company or its Subsidiaries at the time the acquisition or combination was consummated.

      6.Administration of the Plan

      a.Administrator of the Plan. The Plan shall be administered by the Administrator, which shall be the Committee, or, in the absence of the Committee, the Board itself. Any power of the Administrator may also be exercised by the Board. To the extent that any permitted action taken by the Board conflicts with action taken by the Administrator, the Board action shall control.

      b.Powers of Administrator. Subject to the express provisions of the Plan, the Administrator shall be authorized and empowered to do all things that it determines to be necessary or appropriate in connection with the administration of the Plan, including, without limitation:

      1.to prescribe, amend and rescind rules and regulations relating to the Plan and to define terms not otherwise defined herein;

      2.to determine which persons are eligible to receive Awards under the Plan, to which of such persons, if any, Awards shall be granted hereunder, and the timing of any such Awards;

      3.to prescribe and amend the terms of the Award Agreements, to grant Awards and determine the terms and conditions thereof;

      4.to establish and verify the extent of satisfaction of any performance goals or other conditions applicable to the grant, issuance, retention, vesting, exercisability, or settlement of any Award;

      5.to prescribe and amend the terms of or form of any document or notice required to be delivered to the Company by Participants under the Plan;

      6.to determine the extent to which adjustments are required pursuant to Section 14 of the Plan;

      7.to interpret and construe the Plan, any rules and regulations under the Plan and the terms and conditions of any Award granted hereunder, and to make exceptions to any such provisions if the Administrator, in good faith, determines that it is appropriate to do so;

      8.to approve corrections in the documentation or administration of any Award; and

      9.to make all other determinations deemed necessary or advisable for the administration of the Plan.

      A-6       INSMED PROXY STATEMENT


      The Administrator may, in its sole and absolute discretion, without amendment to the Plan but subject to the limitations otherwise set forth in Section 18 of the Plan, reserveswaive or amend the operation of Plan provisions respecting exercise after termination of employment or service to the BoardCompany or an Affiliate. The Administrator may, in its sole and absolute discretion and, except as otherwise provided in Section 18 of Directorsthe Plan, waive, settle or adjust any of the terms of any Award so as to avoid unanticipated consequences or address unanticipated events (including any temporary closure of an applicable stock exchange, disruption of communications, or natural catastrophe).

      c.Determinations by the Administrator. All decisions, determinations and interpretations by the Administrator regarding the Plan, any rules and regulations under the Plan and the terms and conditions of or operation of any Award granted hereunder, shall be final and binding on all Participants, beneficiaries, heirs, assigns or other persons holding or claiming rights under the Plan or any Award. The Administrator shall consider such factors as it deems relevant, in its sole and absolute discretion, to making such decisions, determinations, and interpretations including, without limitation, the recommendations or advice of any officer or other employee of the Company and such attorneys, consultants, and accountants as it may select. Members of the Board and members of the Committee acting under the Plan shall be fully protected in relying in good faith upon the advice of counsel and shall incur no liability except for gross negligence or willful misconduct in the performance of their duties.

      d.Delegation of Authority. To the maximum extent permitted by applicable law, the Committee may by resolution delegate to a committee of one or more members of the Board or one or more officers of the Company the authority to perform any or all things that the Administrator is authorized and empowered to do or perform under the Plan, and for all purposes under the Plan, such officer or officers shall be treated as the Administrator; provided, however, that the resolution so authorizing such officer or officers shall specify the total number of Awards (if any) such officer or officers may award pursuant to such delegated authority; and provided further that in no event shall an officer of the Company be delegated the authority to grant Awards to, or amend Awards held by, individuals who are subject to Section 16 of the Act or who report directly to such officer. No such officer shall designate himself or herself as a recipient of any Awards granted under authority delegated to such officer. In addition, the Administrator may delegate any or all aspects of the day-to-day administration of the Plan to one or more officers or employees of the Company or any Subsidiary, and/or to one or more agents.

      e.Subsidiary Awards. In the case of a grant of an Award to any Participant employed by a Subsidiary, such grant may, if the Administrator so directs, be implemented by the Company issuing any subject shares of Common Stock to the Subsidiary, for such lawful consideration as the Administrator may determine, upon the condition or understanding that the Subsidiary will transfer the shares of Common Stock to the Participant in accordance with the terms of the Award specified by the Administrator pursuant to the provisions of the Plan. Notwithstanding any other provision hereof, such Award may be issued by and in the name of the Subsidiary and shall be deemed granted on such date as the Administrator shall determine.

      7.Plan Awards

      a.Terms Set Forth in Award Agreement. The terms and conditions of each Award shall be set forth in an Award Agreement in a form approved by the Administrator for such Award, which Award Agreement may contain such terms and conditions as specified from time to time by the Administrator, provided such terms and conditions do not conflict with the Plan. The Award Agreement for any Award, as applicable, shall include the time or times at or within which and the consideration, if any, for which any shares of Common Stock may be acquired from the Company. The terms of Awards may vary among Participants, and the Plan does not impose upon the Administrator any requirement to make Awards subject to uniform terms. Accordingly, the terms of individual Award Agreements may vary.

      A-7       INSMED PROXY STATEMENT


      b.Separation from Service. Subject to the express provisions of the Plan, the Administrator shall specify before, at, or after the time of grant of an Award the provisions governing the effect(s) upon an Award of a Participant’s Separation from Service or other termination of service.

      c.Rights of a Shareholder. A Participant shall have no rights as a shareholder with respect to shares of Common Stock covered by an Award until the date the Participant becomes the holder of record of such shares of Common Stock. No adjustment shall be made for dividends or other rights for which the record date is prior to such date, except as provided in Section 10.a or Section 14 of the Plan or as otherwise provided by the Administrator.

      d.Minimum Vesting. Notwithstanding anything in the Plan to the contrary, all Awards granted under the Plan shall be subject to a vesting period of not less than one year from the date of grant; provided, that up to 5% of the Share Pool may be issued pursuant to Awards that are not subject to the minimum vesting requirement set forth in this Section 7(d); provided, further, that the minimum vesting requirement set forth in this Section 7(d) shall not apply with respect to Substitute Awards or with respect to Awards that vest upon a Participant’s death or disability. For the avoidance of doubt, nothing in this Section 7(d) shall limit or restrict the Administrator’s authority to accelerate the vesting or exercisability of all or any portion of an Award following the grant date of such Award in accordance with the provisions of the Plan.

      e.No Payment of Dividends Prior to Vesting. Notwithstanding anything in the Plan to the contrary, to the extent a Participant is eligible to receive dividends or Dividend Equivalents with respect to an Award granted under the Plan, such dividends or Dividend Equivalents shall in no case be paid to the Participant before the vesting of the portion of the Award to which such dividends or Dividend Equivalents relate.

      f.Restriction on Acceleration Following Grant. Following the grant date of an Award, the Administrator shall not accelerate the vesting or exercisability of all or any portion of an Award, unless (i) explicitly provided under the terms of an Award Agreement (which shall be subject to the limitations in Section 7(d) above), (ii) explicitly provided under the terms of an employment or service agreement with a Participant, or (iii) in connection with a Change in Control or a Participant’s death or disability.

      8.Options

      a.Grant, Term and Price. The grant, issuance, retention, vesting, and/or settlement of any Option shall occur at such time and be subject to such terms and conditions as determined by the Administrator or under criteria established by the Administrator, which may include conditions based on continued employment, passage of time, attainment of age and/or service requirements, and/or satisfaction of performance conditions. The term of an Option shall in no event be greater than ten years; provided, however, the term of an Option (other than an Incentive Stock Option) shall be automatically extended if, at the time of its scheduled expiration, the Participant holding such Option is prohibited by law or the Company’s insider trading policy from exercising the Option, which extension shall expire on the thirtieth (30th) day following the date such prohibition no longer applies. The Administrator will establish the price at which Common Stock may be purchased upon exercise of an Option, which, in no event will be less than the Fair Market Value of such shares on the date of grant; provided, however, that the exercise price per share of Common Stock with respect to an Option that is granted as a Substitute Award may be less than the Fair Market Value of the shares of Common Stock on the date such Option is granted if such exercise price is based on a formula set forth in the terms of the options held by such optionees or in the terms of the agreement providing for such merger or other acquisition that satisfies the requirements of Section 409A and/or Section 424 of the Code, as applicable. The exercise price of any Option may be paid in cash or such other method as determined by the Administrator, including an irrevocable commitment by a broker to pay over such amount from a sale of the Shares issuable under an Option, the delivery of previously owned shares of Common Stock or withholding of shares of Common Stock deliverable upon exercise.

      A-8       INSMED PROXY STATEMENT


      b.No Repricing without Shareholder Approval. Other than in connection with a change in the Company’s capitalization (as described in Section 14 of the Plan), at any time when the exercise price of an Option is above the Fair Market Value of a share of Common Stock, the Company shall not, without shareholder approval, (i) reduce the exercise price of such Option, (ii) exchange such Option for cash, another Award, or a new Option or Stock Appreciation Right with a lower exercise or base price, or (iii) otherwise reprice such Option.

      c.No Reload Grants. Options shall not be granted under the Plan in consideration for and shall not be conditioned upon the delivery of shares of Common Stock to the Company in payment of the exercise price and/or tax withholding obligation under any other employee stock option.

      d.Incentive Stock Options. Notwithstanding anything to the contrary in this Section 8, in the case of the grant of an Option intended to qualify as an Incentive Stock Option, if the Participant owns stock possessing more than 10% of the combined voting power of all classes of stock of the Company, the exercise price of such Option must be at least 110% of the Fair Market Value of the shares of Common Stock on the date of grant and the Option must expire within a period of not more than five (5) years from the date of grant. Notwithstanding anything in this Section 8 to the contrary, options designated as Incentive Stock Options shall not be eligible for treatment under the Code as Incentive Stock Options (and will be deemed to be Nonqualified Stock Options) to the extent that either (a) the aggregate Fair Market Value of shares of Common Stock (determined as of the time of grant) with respect to which such Options become exercisable for the first time by the Participant during any calendar year (under all plans of the Company and any Subsidiary) exceeds $100,000, taking Options into account in the order in which they were granted, or (b) such Options otherwise remain exercisable but are not exercised within three (3) months (or such other period of time provided in Section 422 of the Code) of separation of service (as determined in accordance with Section 3401(c) of the Code).

      e.No Shareholder Rights. Participants shall have no voting rights and will have no rights to receive dividends or Dividend Equivalents in respect of an Option or any shares of Common Stock subject to an Option until the Participant has become the holder of record of such shares.

      9.Stock Appreciation Rights

      a.General Terms. The grant, issuance, retention, vesting, and/or settlement of any Stock Appreciation Right shall occur at such time and be subject to such terms and conditions as determined by the Administrator or under criteria established by the Administrator, which may include conditions based on continued employment, passage of time, attainment of age and/or service requirements, and/or satisfaction of performance conditions. Stock Appreciation Rights may be granted to Participants from time to time either in tandem with or as a component of Options granted under the Plan (“tandem SARs”) or not in conjunction with other Awards (“freestanding SARs”). Upon exercise of a tandem SAR as to some or all of the shares covered by the grant, the related Option shall be canceled automatically to the extent of the number of shares covered by such exercise. Conversely, if the related Option is exercised as to some or all of the shares covered by the grant, the related tandem SAR, if any, shall be canceled automatically to the extent of the number of shares covered by the Option exercise. Any Stock Appreciation Right granted in tandem with an Option may be granted at the same time such Option is granted or at any time thereafter before exercise or expiration of such Option, provided that the Fair Market Value of Common Stock on the date of the tandem SAR’s grant is not greater than the exercise price of the related Option. All freestanding SARs shall be granted subject to the same terms and conditions applicable to Options as set forth in Section 8 of the Plan and all tandem SARs shall have the same exercise price and the same term (including any extensions thereof) as the Option to which they relate. Subject to the provisions of Section 8 of the Plan and the immediately preceding sentence, the Administrator may impose such other conditions or restrictions on any Stock Appreciation Right as it shall deem appropriate. Stock Appreciation Rights may be settled in Common Stock, cash, or a combination thereof, as determined by the Administrator and set forth in the applicable Award Agreement.

      A-9      INSMED PROXY STATEMENT


      b.No Repricing without Shareholder Approval. Other than in connection with a change in the Company’s capitalization (as described in Section 14 of the Plan), at any time when the exercise price of a Stock Appreciation Right is above the Fair Market Value of a share of Common Stock, the Company shall not, without shareholder approval (i) reduce the exercise or base price of such Stock Appreciation Right, (ii) exchange such Stock Appreciation Right for cash, another Award or a new Option or Stock Appreciation Right with a lower exercise or base price, or (iii) otherwise reprice such Stock Appreciation Right.

      c.No Shareholder Rights. Participants shall have no voting rights and will have no rights to receive dividends or Dividend Equivalents in respect of an Award of Stock Appreciation Rights or any shares of Common Stock subject to an Award of Stock Appreciation Rights until the Participant has become the holder of record of such shares.

      10. Restricted Stock and Restricted Stock Units

      a.Vesting and Performance Conditions. The grant, issuance, retention, vesting, and/or settlement of any Restricted Stock or Restricted Stock Unit Award shall occur at such time and be subject to such terms and conditions as determined by the Administrator or under criteria established by the Administrator, which may include conditions based on continued employment, passage of time, attainment of age and/or service requirements, and/or satisfaction of performance conditions.

      b.Dividends and Distributions. Participants in whose name Restricted Stock is granted shall be entitled to receive all dividends and other distributions paid with respect to those shares of Common Stock, unless determined otherwise by the Administrator. The Administrator will determine whether any such dividends or distributions will be automatically reinvested in additional Restricted Stock and/or subject to the same restrictions on transferability as the Restricted Stock with respect to which they were distributed or whether such dividends or distributions will be paid in cash. Unless otherwise provided in the Award Agreement, during the period prior to shares being issued in the name of a Participant under any Restricted Stock Unit, the Company shall pay or accrue Dividend Equivalents on each date dividends on Common Stock are paid, subject to such conditions as the Administrator may deem appropriate. The time and form of any such payment of Dividend Equivalents shall be specified in the Award Agreement. Notwithstanding anything herein to the contrary, in no event will dividends or Dividend Equivalents be paid in either cash or shares (other than shares subject to the same restrictions as the associated Restricted Stock) with respect to any Award of Restricted Stock or Restricted Stock Units prior to the time specified in Section 7(e).

      c.Voting Rights. Unless otherwise determined by the Administrator, Participants holding shares of Restricted Stock granted hereunder may exercise full voting rights with respect to those shares during the period of restriction. Participants shall have no voting rights with respect to shares of Common Stock underlying Restricted Stock Units unless and until such shares are reflected as issued and outstanding shares on the Company’s stock ledger.

      11. Performance Awards

      a.General Terms. The Administrator may establish performance conditions and level of achievement versus such conditions that shall determine the number of Options, Stock Appreciation Rights or shares of Common Stock to be granted, retained, vested, issued or issuable under or in settlement of, or the cash amount payable pursuant to, an Award.

      A-10        INSMED PROXY STATEMENT


      b.Timing and Form of Payment. The Administrator shall determine the timing of payment of any award subject to performance conditions. Payment of the amount due under such an award may be made in cash or in Common Stock, as determined by the Administrator.

      c.Discretionary Adjustments. Notwithstanding satisfaction of any performance goals, the amount paid under an award subject to either financial performance and/or personal performance evaluations may be adjusted by the Administrator on the basis of such further considerations as the Administrator shall determine.

      12. Deferral of Payment and Section 409A

      The Administrator may, in an Award Agreement or otherwise, provide for the deferred delivery of shares of Common Stock upon settlement, vesting or other events with respect to Restricted Stock or Restricted Stock Units. Notwithstanding anything herein to the contrary, the Administrator may, in its sole and absolute discretion, deny any deferral of the delivery of shares of Common Stock or any other payment with respect to any Award if the Administrator determines, in its sole and absolute discretion, that the deferral would result in the imposition of the additional tax under Section 409A(a)(1)(B) of the Code. The Plan and each Award Agreement shall be interpreted such that each Award complies with, or is exempt from, Section 409A of the Code. However, the Company shall have no liability to a Participant, or any other party, if an Award that is intended to be exempt from, or compliant with, Section 409A of the Code is not so exempt or compliant or for any action taken by the Administrator or the Board.

      13. Conditions and Restrictions Upon Securities Subject to Awards

      The Administrator may provide that the Common Stock issued upon exercise of an Option or Stock Appreciation Right or otherwise subject to or issued under an Award shall be subject to such further agreements, restrictions, conditions or limitations as the Administrator in its discretion may specify prior to the exercise of such Option or Stock Appreciation Right or the grant, vesting or settlement of such Award, including without limitation, conditions on vesting or transferability, forfeiture or repurchase provisions and method of payment for the Common Stock issued upon exercise, vesting or settlement of such Award (including the actual or constructive surrender of Common Stock already owned by the Participant), or payment of taxes arising in connection with an Award. Without limiting the foregoing, such restrictions may address the timing and manner of any resales by the Participant or other subsequent transfers by the Participant of any shares of Common Stock issued under an Award, including without limitation (i) restrictions under an insider trading policy or pursuant to applicable law, (ii) restrictions designed to delay and/or coordinate the timing and manner of sales by the Participant and holders of other Company equity compensation arrangements, (iii) restrictions as to the use of a specified brokerage firm for such resales or other transfers, and (iv) provisions requiring Common Stock be sold on the open market or to the Company in order to satisfy tax withholding or other obligations.

      14. Adjustment of and Changes in the Stock; Change in Control

      a.Adjustments Upon Certain Unusual or Nonrecurring Events. The number and kind of shares of Common Stock available for issuance under the Plan (including under any Awards then outstanding), and the number and kind of shares of Common Stock subject to the limits set forth in Section 5 of the Plan, shall be equitably adjusted by the Administrator to reflect any reorganization, reclassification, combination of shares, stock split, reverse stock split, spin-off, dividend or distribution of securities, property or cash (other than regular, quarterly cash dividends), or any other event or transaction that affects the number or kind of shares of Common Stock outstanding. Such adjustment may be designed to comply with Section 424 of the Code or may be designed to treat the shares of Common Stock available under the Plan and subject to Awards as if they were all outstanding on the record date for such event or transaction or to increase the number of such shares of Common Stock to reflect a deemed reinvestment in shares of Common Stock of the amount distributed to the Company’s security holders. The terms of any outstanding Award shall also be equitably adjusted by the Administrator as to price, number or kind of shares of Common Stock subject to such Award, vesting, and other terms to reflect the foregoing events, which adjustments need not be uniform as between different Awards or different types of Awards. No fractional shares of Common Stock shall be issued pursuant to such an adjustment.

      f.The Company shall notify Participants holding Awards subject to any adjustments pursuant to this Section 14 of such adjustment, but (whether or not notice is given) such adjustment shall be effective and binding for all purposes of the Plan.
