The Annual Meeting materials include the Notice of Annual Meeting of Stockholders, Proxy Statement, and Annual Report to stockholders, each of which has been furnished to you over the internet or, if you have requested a paper copy of the materials, by mail.

Whether or not you plan to attend the Annual Meeting, please cast your vote as soon as possible by Internet, telephone or, if you received a paper copy of the meeting materials by mail, by completing and returning the enclosed proxy card in the postage-prepaid envelope to ensure that your shares will be represented. Your vote by written proxy will ensure your representation at the Annual Meeting regardless of whether or not you attend virtually.

Key Business Highlights
We are a leading digital healthcare company that is in the business of designing, developing, and commercializing device- based technology to provide cardiac monitoring services that we believe allow clinicians to diagnose certain arrhythmias quicker and with greater efficiency than other services that rely on traditional technology.
We have developed a proprietary system that combines an FDA-cleared and CE-marked, wire-free, patch-based, 14-day wearable biosensor that continuously records electrocardiogram (“ECG”) data with a proprietary, FDA-cleared, CE-marked cloud-based data analytic software to help physicians monitor patients and diagnose arrhythmias (collectively, the “Zio System”). We have provided our Zio ambulatory cardiac monitoring services, including long-term continuous monitoring, short-term continuous monitoring, and mobile cardiac telemetry (“MCT”) monitoring services (collectively, the “Zio Services”), using our Zio System. These services are offered through three Zio System options — the Zio Monitor System, the Zio XT System, and the Zio AT System.
Since first receiving clearance from the U.S. Food and Drug Administration (“FDA”) for our technology in 2009, we have supported physician and patient use of our technology and provided ambulatory cardiac monitoring services from our Medicare-enrolled independent diagnostic testing facilities (“IDTFs”) and with our qualified technicians. Over this period of time, we have provided the Zio Services to over six million patients and have collected over 1.8 billion hours of curated heartbeat data.
In 2023, we continued to drive significant growth in our core business, and we believe that our ongoing accomplishments and investments will provide the foundation for sustained value creation over the long term. Over the past five years, our revenue compound annual growth rate, or CAGR, grew over 27%, reflecting continued resilience amid various micro- and macro-economic challenges. Our significant financial and operational highlights for 2023 included:
Accelerated momentum in core U.S. commercial business
Grew full year 2023 patient registrations by 24% compared to full year 2022;
Drove record full year of new account onboarding for Zio long-term continuous monitoring (“LTCM”) service in the United States;
Launched our next generation Zio Monitor patch that builds on the high performance of Zio XT, together with an enhanced Zio Monitor Service that includes an updated patient experience to simplify enrollment and improve patient case management, and a refreshed patient mobile application; and
Published the Cardiac Ambulatory Monitor EvaLuation of Outcomes and Time to Events (“CAMELOT”) study in the peer-reviewed American Heart Journal in December 2023, demonstrating higher clinical diagnostic yield and lower odds of retesting with Zio LTCM compared to other LTCM as well as to event recorder, mobile cardiac telemetry, and Holter.
Advanced initiatives within growth pillars to drive future value creation
Zio Monitor System granted high medical needs designation by the Japanese Ministry of Health, Labour, and Welfare - reflecting recommendation by the Japanese Heart Rhythm Society - and we submitted a Shonin pre-market application to the Japanese Pharmaceutical and Medical Device Agency for regulatory approval in Japan;
Received European Union CE marking under Medical Devices Regulation for the Zio monitor and Zio ECG Utilization Software (“ZEUS”) System, which supports the capture and analysis of ECG data recorded by the Zio Monitor patch at the end of the wear period;
Opened a global business services center in Manila, Philippines, to position us to maintain patient satisfaction, scale globally, and perform more efficiently; and
Generated additional published evidence of feasibility supporting the potential to expand into predictive models.
Operated with discipline and efficiency to drive financial sustainability
Revenue of $492.7 million increased by approximately 20% compared to full year 2022;
Gross margin of 67.3% decreased by 120-basis point compared to full year 2022;

Net loss of $123.4 million reflected an increased loss of $7.3 million compared to full year 2022;

Environment, Social and Governance Highlights
We believe that effectively managing ESG risks and opportunities drives business success, and that when fully integrated into the business, ESG can provide a competitive advantage. In 2022, we set out on a journey to develop iRhythm’s approach to ESG by conducting an ESG Priority Assessment to identify the ESG priority topics that are important to internal and external stakeholders. We also began operationalizing ESG within the organization by forming an ESG Steering Committee and multiple ESG Working Groups, which focus on specific ESG substantive areas or work streams. In addition, in 2023, we established formal board oversight of ESG by revising the charters of two committees of our Board of Directors, including the Nominating and Corporate Governance Committee and the Compensation and Human Capital Management Committee. We continue to work as an organization to advance our strategic ESG roadmap by pursuing ESG work streams.
During 2023 Institutional Shareholder Services group of companies (ISS) provided iRhythm with “Prime” status for the first time. Prime status is for companies achieving what ISS determines to be best in class ESG performance, based on sector exposure to environmental, social and governance impacts.
Our strategic ESG roadmap is continuously evolving based on progress, feedback, and business and external environment changes, and as we move forward, we plan to regularly review and revisit our ESG priority topics, our ESG measures and initiatives, and any ESG goals so that we can dynamically support the success of our business by addressing those topics, that make our business more sustainable. We believe that advancing the interests of our stakeholders supports the sustainability and success of our business, and so as we implement our ESG program, we plan to regularly consult internal and external stakeholders to take into account the views and perspectives of those groups that are critical to our business and which we impact by virtue of operating our business, our employees, customers, suppliers, investors, communities and others.

Virtual Meeting Philosophy

The Company has held its annual meeting of stockholders as a virtual meeting via the Internet since 2020. The Company also offers stockholders the option to ask questions live via telephone. The Board believes that holding the annual meeting of stockholders in a virtual format provides the opportunity for participation by a broader group of stockholders, while reducing the costs associated with planning, holding and arranging logistics for in-person meeting proceedings. This balance allows the meetings to remain focused on matters directly relevant to the interests of stockholders in a way that recognizes the value to stockholders of an efficient use of Company resources. The Board intends that the virtual meeting format provide stockholders a level of transparency as close as possible to the traditional in-person meeting format and takes the following steps to ensure such an experience:

providing stockholders with the ability to submit appropriate questions in advance of the meeting to ensure thoughtful responses from management and the Board;
providing stockholders with the ability to submit appropriate questions real-time either via telephone or the meeting website, limiting questions to one per stockholder unless time otherwise permits;
answering as many questions submitted in accordance with the meeting rules of conduct as possible in the time allotted for the meeting without discrimination;
publishing all questions submitted in accordance with the meeting rules of conduct with answers following the meeting, including those not addressed directly during the meeting; and
offering separate engagement opportunities with stockholders on appropriate matters of governance or other relevant topics as outlined under the section titled “Communications with the Board of Directors” below.

Holders of our common stock as of the close of business on March 31, 2022, the record date for the Annual Meeting, may vote at the Annual Meeting. As of the record date, there were 29,768,708 shares of our common stock outstanding. In deciding all matters at the Annual Meeting, each stockholder2024, will be entitled to one vote for each share of our common stock held by them on the record date. Stockholders are not permitted to cumulate votes with respect to the election of directors.
Registered Stockholders. If shares of our common stock are registered directly in your name with our transfer agent, you are considered the stockholder of record with respect to those shares and the Notice was provided to you directly by us. As the stockholder of record, you have the right to grant your voting proxy directly to the individuals listed on the proxy card or vote while virtually attending the Annual Meeting. Throughout this Proxy Statement, we refer to these registered stockholders as “stockholders of record.”
Street Name Stockholders. If shares of our common stock are held on your behalf in a brokerage account or by a bank or other nominee, you are considered to be the beneficial owner of shares that are held in “street name,” and the Notice was forwarded to you by your broker or nominee, who is considered the stockholder of record with respect to those shares. As the beneficial owner, you have the right to direct your broker, bank or other nominee as to how to vote your shares. Beneficial owners are also invited to virtually attend the Annual Meeting. However, since a beneficial owner is not the stockholder of record, you may not vote your shares of our common stock during the virtual Annual Meeting unless you follow your broker’s procedures for obtaining a legal proxy. If you request a printed copy of our proxy materials by mail, your broker, bank or other nominee will providea voting instruction form for you to use. Throughout this Proxy Statement, we refer to stockholders who hold their shares through a broker, bank or other nominee as “street name stockholders.”
How many votes are needed for approval of each proposal?
Proposal No. 1: The election of directors requires a plurality vote of the shares of our common stock present in attendance or by proxy at the virtual Annual Meeting and entitled to vote thereon to be approved. “Plurality” means that the nominees who receive the largest number of votes cast “for” are elected as directors. As a result, any shares not voted “for” a particular nominee (whether as a result of stockholder abstention or a broker non-vote) will not be counted in such nominee’s favor and will have no effect on the outcome of the election. A “broker non-vote” occurs when a nominee holding shares for a beneficial owner does not vote on a particular proposal because the nominee does not have discretionary voting power with respect to that item and has not received instructions from the beneficial owner. You may vote “for” or “withhold” on each of the nominees for election as a director.

Proposal No. 2: The ratification of the appointment of PricewaterhouseCoopers LLP requiresobtained if the affirmative vote of a majority of the shares of our common stock present in attendance or by proxy at the virtual Annual Meeting and entitled to vote thereon to be approved.

At the Annual Meeting, abstentions or withhold votes will have no effect on Proposal No. 1, Proposal No. 2, Proposal No. 3 or Proposal No. 5 and will have the same effect as a vote against Proposal No. 4.
Broker non-votes occur when shares held by a broker for a beneficial owner are not voted because the broker did not receive voting instructions from the beneficial owner and lacked discretionary authority to vote the shares. Under Delaware law, broker non-votes are counted as present and entitled to vote for purposes of determining whether a quorum is present. However, brokers have limited discretionary authority to vote shares that are beneficially owned. While a broker is entitled to vote shares held for a beneficial owner on “routine” matters without instructions from the beneficial owner of those shares, absent instructions from the beneficial owner of such shares, a broker is not entitled to vote shares held for a beneficial owner on “non-routine” matters. At our Annual Meeting, only Proposal No. 2 is considered a routine matter and brokers have discretionary authority to vote shares that are beneficially owned on Proposal No. 2. If a broker chooses not to vote shares for or against Proposal No. 2, it will have the same effect as an abstention. The other proposals presented at the Annual Meeting are non-routine matters. Broker non-votes are not deemed to be shares entitled to vote on and will have no effect on the outcome of Proposal No. 1, Proposal No. 3 and Proposal No. 5 and will have the same effect as a vote against Proposal No. 4.

Corporate Governance Standards and Director Independence
We are strongly committed to good corporate governance practices. These practices provide an important framework within which our Board of Directors and management can pursue our strategic objectives for the benefit of our stockholders.

Corporate Governance Principles
Our Board of Directors has adopted Corporate Governance Guidelines that set forth expectations for directors, director independence standards, board committee structure and functions, and other policies for the governance of the Company. Among other things, our Corporate Governance Guidelines provide:
To satisfy their duty in overseeing company management and the ethical operation of the company, the directors will announce preliminary voting resultstake a proactive, focused approach to their position, and set standards to ensure that the company is committed to business excellence, ethical and honest conduct, and highest levels of integrity.
There will at all times be a majority of independent directors serving on the Board of Directors. Eight out of nine of our directors at the virtualtime of the Annual Meeting. Meeting are independent.
The Board of Directors shall have responsibility for succession planning concerning the Chief Executive Officer, and the company’s NEOs and the Compensation and Human Capital Management Committee shall plan for and conduct reviews with respect to succession planning for other key employees identified by the Chief Executive Officer.
The Audit Committee, Compensation and Human Capital Management Committee and Nominating and Corporate Governance Committee must each be, and currently are, composed of a majority of independent directors.
The Nominating and Corporate Governance Committee and the Board of Directors will evaluate each individual director or potential director in the context of the membership of the Board of Directors as a group, with the objective of having a group that can best perpetuate the success of the business and represent stockholder interests through the exercise of sound judgment using its diversity of background and experience in the various areas.
Our Corporate Governance Guidelines are available without charge on the “Investor Relations” section of our website, which is located at https://investors.irhythmtech.com, by clicking “Governance Documents and Charters” in the “Governance” section of our website. Our Nominating and Corporate Governance Committee reviews the Corporate Governance Guidelines periodically, and changes are recommended to our Board of Directors as warranted.

Board of Directors and Committee Self-Evaluations
Throughout the year, our Board of Directors discusses corporate governance practices with management and third-party advisors, including the company’s outside legal counsel, to ensure that the Board of Directors and its committees follow practices that are optimal for the company and its stockholders. Based on an evaluation process established and implemented by our Nominating and Corporate Governance Committee pursuant to the committee’s authority set forth in its charter, the Board of Directors, each committee thereof and each director conduct an annual self-evaluation in order to determine whether the Board of Directors and its committees and directors are functioning effectively. The Nominating and Corporate Governance Committee is responsible for establishing the evaluation criteria and implementing the process for this evaluation, as well as considering other corporate governance principles that may, from time to time, merit consideration by the Board of Directors.
The assessment of the Board of Directors is administered by the chairman of the Board of Directors, and Committee assessments are administered by the applicable chairperson of each committee.
The Board of Directors and committees assess, on an annual basis, several factors they believe to be essential in the effective performance of the Board of Directors and each committee, including:
overall effectiveness of the Board of Directors and its committees, including in relation to progress in addressing the annual board or committee priorities;
structure and composition of the Board of Directors and committees, including with respect to director independent, skills and diversity;
effective oversight and risk management;
sufficient and substantive communications between the Board of Directors and the company’s management;
facilitation of board impact on stockholder value creation; and
suggested improvements and best practices for the Board of Directors or committees.
The Nominating and Corporate Governance Committee reviews evaluations of the Board of Directors, and each committee reviews its respective report. All evaluation responses are shared with the full Board of Directors. Following the annual evaluation process, the Board of Directors and its committees assess the opportunities and suggestions provided in the feedback received and implement updates and changes as appropriate.

Board Nomination Process
The Board of Directors considers any nominations of director candidates validly made by stockholders in accordance with applicable laws, rules and regulations and the provisions of the company’s bylaws.
In accordance with the Nominating and Corporate Governance Charter, the Nominating and Corporate Governance Committee determines and make recommendations to the full Board of Directors for its approval, the desired qualifications, qualities, skills and other expertise required to be considered in selecting nominees for director, such as character, professional ethics and integrity, judgment, business acumen, proven achievement and competence in one’s field, the ability to exercise sound business judgment, tenure on the Board of Directors and skills that are complementary to the Board of Directors, an understanding of the company’s business, an understanding of the responsibilities that are required of a member of the Board of Directors, other time commitments, diversity with respect to professional background, education, race, ethnicity, gender, being a member of an underrepresented community, age and geography, as well as other individual qualities and attributes that contribute to the total mix of viewpoints and experience represented on the Board of Directors.
Further, the Nominating and Corporate Governance Committee searches for, identifies, evaluates and selects, or recommends for the selection by the Board of Directors, candidates to fill new positions or vacancies on the Board of Directors consistent with the company’s director criteria, as included in the Corporate Governance Guidelines, and reviews any candidates recommended by stockholders, provided such stockholder recommendations are made in compliance with the Corporation’s bylaws and its stockholder nominations and recommendations policies and procedures. The Nominating and Corporate Governance Committee shall select prospective members of the Board of Directors that are of high character and integrity. As stated in our Corporate Governance Guidelines, the composition of the Board of Directors should reflect a diversity of
17


background and experience to best perpetuate the success of the business and represent stockholder interests through the exercise of sound judgment. Accordingly, the Nominating and Corporate Governance Committee, and any search firm it engages, will include women, minority and underrepresented community candidates in the pool of each director search.

Board Succession
The Nominating and Corporate Governance Committee evaluates the current size, composition, organization and governance of the Board of Directors and its committees, determines future requirements and makes recommendations to the Board of Directors for approval consistent with our director criteria.
As part of the refreshment process for the Board of Directors, the Nominating and Corporate Governance Committee evaluates the performance of individual members of the Board of Directors eligible for re-election, and selects, or recommends for the selection by the Board of Directors, the director nominees for election to the Board of Directors by the stockholders at the company’s annual meeting of stockholders or any special meeting of stockholders at which directors are to be elected.
We also develop and review periodically the policies and procedures for considering stockholder nominees for election to the Board of Directors, and we evaluate and recommend termination of membership of individual directors for cause or for other appropriate reasons.
The Nominating and Corporate Governance Committee does not have a written policy on the consideration of director candidates recommended by stockholders. It is the view of the Board of Directors that all candidates, whether recommended by a stockholder or the Nominating and Corporate Governance Committee, shall be evaluated based on the same established criteria for persons to be nominated for election to the Board of Directors and its committees. The established criteria for persons to be nominated for election to the Board of Directors and its committees, taking into account the composition of the Board of Directors as a whole, at a minimum, includes:
character, professional ethics and integrity, judgment, and business acumen;
proven achievement and competence in the candidate’s field;
the ability to exercise sound business judgment;
tenure on the Board of Directors and skills that are complementary to the Board of Directors;
an understanding of the company’s business;
an understanding of the responsibilities that are required of a member of the Board of Directors;
other time commitments;
diversity with respect to professional background, education, race, ethnicity, gender, being a member of an underrepresented community, age and geography, as well as other individual qualities and attributes that contribute to the total mix of viewpoints and experience represented on the Board of Directors; and
for incumbent members of the Board, the past performance of the incumbent director.
In addition, the Nominating and Corporate Governance Committee and the Board of Directors consider a candidate’s experience in the healthcare industry and other relevant industries. The priorities and emphasis of the Nominating and Corporate Governance Committee and of the Board of Directors with regard to these factors change from time to time to take into account changes in the company’s business and other trends, as well as the portfolio of skills and experience of current and prospective members of the Board of Directors. The Nominating and Corporate Governance Committee and the Board of Directors review and assess the continued relevance of and emphasis on these factors as part of the Board of Directors’ annual self-assessment process and in connection with candidate searches to determine if they are effective in helping to satisfy the Board of Directors’ goal of creating and sustaining a Board of Directors that can appropriately support and oversee the company’s activities.

The listing rules of the Nasdaq Stock Market LLC (“Nasdaq”) generally require that independent directors constitute a majority of a listed company’s Board of Directors. In addition, the Nasdaq rules require that, subject to specified exceptions, each member of a listed company’s audit, compensation and nominating and corporate governance committees must be an “independent director.” Under the rules of Nasdaq, a director will only qualify as an “independent director” if, in the opinion of that company’s Board of Directors, that person does not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. Additionally, compensation committee members must not have a relationship with the listed company that is material to the director’s ability to be independent from management in connection with the duties of a compensation committee member.
In addition, Audit Committee members must also disclose voting results onsatisfy the independence criteria set forth in Rule 10A-3 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). In order to be considered independent for purposes of Rule 10A-3, a Current Report on Form 8-Kmember of an audit committee of a listed company may not, other than in his or her capacity as a member of the audit committee, the Board of Directors, or any other board committee: accept, directly or indirectly, any consulting, advisory, or other compensatory fee from the listed company or any of its subsidiaries; or be an affiliated person of the listed company or any of its subsidiaries.
Our Board of Directors has undertaken a review of the independence of each director and considered whether each director has a material relationship with us that we will file withcould compromise his or her ability to exercise independent judgment in carrying out his or her responsibilities. As a result of this review, our Board of Directors determined that each of our directors other than Mr. Blackford are “independent directors” as defined under the applicable rules and regulations of the Securities and Exchange Commission (the “SEC”) within fourand the listing requirements and rules of Nasdaq. In making these determinations, our Board of Directors reviewed and discussed information provided by the directors and by us with regard to each director’s business days after the Annual Meeting. If final voting results are not availableand personal activities and relationships as they may relate to us and our management, including the beneficial ownership of our common stock by each non-employee director and the transactions involving them described in the section titled “Certain Relationships and Related Party Transactions.”

Board Leadership Structure
Our Corporate Governance Guidelines provide that our Board of Directors shall be free, in accordance with our bylaws, to choose its chairperson in any way that it considers in the best interests of our company, and in making this determination, directors may take into consideration the interests of other stakeholders.
Currently, our Board of Directors believes that it should maintain flexibility to select the chairperson of our Board of Directors and adjust our board leadership structure from time to filetime.
Independent Chairperson of our BoardChief Executive Officer
Abhijit Y. Talwalkar has served as the independent chairperson of our Board of Directors since May 2016.

Our Board of Directors believes that Mr. Talwalkar’s deep technology knowledge and extensive experience in executive and board leadership roles at other technology companies make him well qualified to serve as chair of our Board of Directors.
Quentin Blackford has served our Chief Executive Officer since October 2021.

As CEO, Mr. Blackford manages the business of the company and executes the strategy developed with our Board of Directors.
Our Corporate Governance Guidelines also provide that, when the Board of Directors does not have an independent chairperson, our Board of Directors will appoint a Current Report on Form 8-K within four business days after“lead independent director.” In the Annual Meeting, weevent a lead independent director is appointed, he or she will file a Current Report on Form 8-K to publish preliminary results and will provide the final results in an amendment to the Current Report on Form 8-K as soon as they become available.

Our Board of Directors’ Role in Risk Oversight
Our Board of Directors, as a whole, has responsibility for risk oversight, although the committees of our Board of Directors oversee and review risk areas that are particularly relevant to them. The risk oversight responsibility of our Board of Directors and its committees is supported by our management reporting processes, which are designed to provide visibility to our Board of Directors and to our personnel that are responsible for risk assessment and information about the identification, assessment and management of critical risks and management’s risk mitigation strategies. These areas of focus include competitive, economic, operational, financial (accounting, credit, investment, liquidity and tax), legal, regulatory, cybersecurity, privacy, compliance and reputational risks.
22


THE BOARD
Our Board of Directors reviews strategic and operational risk in the context of discussions, question and answer sessions, and reports from the management team at each regular board meeting, as well as reports from other third-party experts from time to time, receives reports on all significant committee activities at each regular board meeting, and evaluates the risks inherent in significant transactions.
AUDIT COMMITTEE
Our Audit Committee assists our Board of Directors in fulfilling its oversight responsibilities with respect to risk management. Our Audit Committee reviews our major financial and enterprise risk exposures, including technology, privacy, cybersecurity and other information technology risks, among other things, discusses with management, our independent auditor and our internal auditor guidelines and policies with respect to risk assessment and risk management.
COMPENSATION AND HUMAN CAPITAL MANAGEMENT COMMITTEEGOVERNANCE COMMITTEE
Our Compensation and Human Capital Management Committee evaluates our major compensation-related risk exposure and the steps management has taken to monitor or mitigate such exposures.Our Nominating and Corporate Governance Committee assesses risks relating to ESG matters.
We believe this division of responsibilities is an effective approach for addressing the risks we face and that our board leadership structure supports this approach. Each committee of our Board of Directors meets with key management personnel and representatives of outside advisors to oversee risks associated with their respective principal areas of focus.
23



Cybersecurity and Privacy Risk Oversight
Cybersecurity is an important part of our risk management at iRhythm. Our cybersecurity program includes mitigating risks for our company and for other companies that may have access to our data and systems. Our Board of Directors recognizes the critical importance of maintaining the trust and confidence of our customers, clients, business partners, and employees. The cybersecurity and privacy risk oversight responsibility of our Board of Directors and its committees is supported by our cybersecurity management reporting processes, which are designed to provide visibility to our Board of Directors and to our personnel that are responsible for risk assessment and information about the identification, assessment, and management of critical risks and management’s risk mitigation strategies. These areas of focus include risks from cybersecurity threats as well as competitive, economic, operational, financial, legal, regulatory, privacy, compliance, and reputational risks, among others. We understand that our customers, patients, and stakeholders entrust us with sensitive data, including Protected Health Information, and we take this responsibility seriously.
Our Board of Directors has an important role in the oversight of the company’s cybersecurity risk management and strategy and has delegated certain components of such oversight related to the security of and risks related to computerized information and technology systems across the company, as well as by risk area (including privacy, data security, and cybersecurity matters), to the Audit Committee, which regularly interacts with our Vice President of Cybersecurity (“VP of Cybersecurity”) and Chief Risk Officer (“CRO”). We also regularly engage external parties to assist in the review of our cybersecurity risk oversight processes.
We have established policies to govern the security of our systems and the protection of customer and patient data, which include regular system updates and patches, employee training on cybersecurity and HIPAA best practices, incident reporting, and the use of encryption to secure sensitive information. Our Cybersecurity department, which reports to our VP of Cybersecurity, is responsible for our cybersecurity program and our Global Risk & Integrity department, which reports to our CRO, is responsible for our privacy program as further discussed below. To identify, assess, and manage material cybersecurity risks, our Cybersecurity team uses a cybersecurity risk assessment process aligned with leading frameworks such as the National Institute of Standards and Technology’s (“NIST”) Cybersecurity Framework and HIPAA. To ensure appropriate and consistent risk evaluation and decision-making processes among our Cybersecurity and Global Risk & Integrity departments, we utilize an Adjusted Risk Rating (“ARR”) system that considers certain attributes that represent impact to the Company, and we prioritize our actions based on our ARR system. Our cybersecurity risk assessment program provides the underlying basis for the activities our Cybersecurity and Global Risk & Integrity departments take to identify and mitigate risks from, as well as develop risk management and response strategies for, evolving and emerging cybersecurity threats.
In addition, we also regularly perform phishing tests on our employees and review our training plan at least annually for appropriate updates to address results from this testing. Further, we are focused on building and maintaining a positive cybersecurity culture through a combination of trainings, educational tools, videos, and other cybersecurity awareness initiatives. On top of annual information security awareness training for our employees, we also provide focused training for certain departments. Our security training incorporates awareness of cyber threats (including malware, ransomware, and social engineering attacks), password hygiene, and incident reporting process, as well as physical security best practices.
We engage in the periodic assessment of our policies, standards, processes, and practices that are designed to address cybersecurity threats and incidents, internally and through assessments by external providers. These efforts include a wide range of activities, including audits, assessments, tabletop exercises, threat modeling, vulnerability testing, penetration testing, and other exercises focused on evaluating the effectiveness of our cybersecurity measures and planning. Assessments by external providers of our cybersecurity measures include information security maturity assessments, audits, and independent reviews of our information security control environment and operating effectiveness. The results of such internal and external assessments, audits, and reviews are reported to the Audit Committee and the Board of Directors, and we adjust our cybersecurity policies, standards, processes, and practices as necessary based on the information provided by these assessments, audits, and reviews.

ESG Priority Topics
In 2022, we conducted our first ESG Priority Assessment, one of the resources that guides our overall ESG strategy. The ESG Priority Assessment was designed to identify the environmental, social and governance topics with the greatest impact on our business strategy, operations and value creation. Through this process, we identified a list of 33 relevant ESG issues and opportunities that were consolidated into 12 ESG topics using the outputs from our business analysis, peer benchmarking and review of stockholder priorities. To prioritize the 12 ESG topics and conduct an inventory of recently completed and ongoing workstreams, we engaged with members of our leadership team and internal technical specialists closest to the relevant issues and opportunities. Using questionnaires and targeted interviews, we collected data on the relative importance of the ESG topics and their potential impacts on our business and success. As risks change over time, we will review and refresh our priority assessment regularly to keep track of evolving ESG priorities and support program relevance and effectiveness. ESG priority topics identified included the following:
Access and Affordability
Access and affordability are high priority ESG topics for the life sciences industry. As a leading digital healthcare company, our vision is to provide better health for all, and we work to ensure fair pricing practices given our customer base while we find and realize new opportunities associated with expanded access to health care. We aim to provide the best clinical care to the patient, irrespective of their ability to pay. We are dedicated to helping patients get the care they need and have demonstrated a commitment to providing financial support for those patients who need it.
Human Capital Management and Diversity, Equity and Inclusion
At iRhythm, the growth and success of our employees is a top priority, as it impacts our performance as a digital healthcare company and our ability to redefine the way cardiac arrhythmias are clinically diagnosed. We are committed to an inclusive and representative culture. We recognize, celebrate and leverage a diversity of ideas, skills and experiences, and this approach defines how we build our teams, cultivate leaders, and create an inclusive environment where each annual meetingemployee can bring their full self to work.

Sustainability
We recognize that environmental sustainability is integral to producing world-class products, and we see environmental sustainability and efficiency as important sources of value creation at iRhythm. Having a strong sustainability program in place is important to meet the growing expectations of our stakeholders, including patients, providers and stockholders. And we see our sustainability strategy as a key cost saving initiative, where reductions in the amount of materials used in our products, improvements in the energy efficiency of our products and expanding circularity measures at the end of our product lifecycle help to improve our bottom line.
Our sustainability strategy covers our own operational footprint, including our limited use of energy and water, efforts to minimize the amount of waste generated and managing climate-related risks and greenhouse gas emissions. As the leading provider of single-use cardiac diagnostic devices, our sustainability strategy also includes efforts to minimize the environmental impact of our products.

We are continually improving our environmental, health and safety program through benchmarking and the adoption of better practices.

Cybersecurity and Privacy Risk Oversight
Cybersecurity is qualifiedan important part of our risk management at iRhythm. Our cybersecurity program includes mitigating risks for our company and for other companies that may have access to serveour data and systems. Our Board of Directors recognizes the critical importance of maintaining the trust and confidence of our customers, clients, business partners, and employees. The cybersecurity and privacy risk oversight responsibility of our Board of Directors and its committees is supported by our cybersecurity management reporting processes, which are designed to provide visibility to our Board of Directors and to our personnel that are responsible for risk assessment and information about the identification, assessment, and management of critical risks and management’s risk mitigation strategies. These areas of focus include risks from cybersecurity threats as well as competitive, economic, operational, financial, legal, regulatory, privacy, compliance, and reputational risks, among others. We understand that our customers, patients, and stakeholders entrust us with sensitive data, including Protected Health Information, and we take this responsibility seriously.
Our Board of Directors has an important role in the oversight of the company’s cybersecurity risk management and strategy and has delegated certain components of such oversight related to the security of and risks related to computerized information and technology systems across the company, as well as by risk area (including privacy, data security, and cybersecurity matters), to the Audit Committee, which regularly interacts with our Vice President of Cybersecurity (“VP of Cybersecurity”) and Chief Risk Officer (“CRO”). We also regularly engage external parties to assist in the review of our cybersecurity risk oversight processes.
We have established policies to govern the security of our systems and the protection of customer and patient data, which include regular system updates and patches, employee training on cybersecurity and HIPAA best practices, incident reporting, and the use of encryption to secure sensitive information. Our Cybersecurity department, which reports to our VP of Cybersecurity, is responsible for our cybersecurity program and our Global Risk & Integrity department, which reports to our CRO, is responsible for our privacy program as further discussed below. To identify, assess, and manage material cybersecurity risks, our Cybersecurity team uses a cybersecurity risk assessment process aligned with leading frameworks such as the National Institute of Standards and Technology’s (“NIST”) Cybersecurity Framework and HIPAA. To ensure appropriate and consistent risk evaluation and decision-making processes among our Cybersecurity and Global Risk & Integrity departments, we utilize an Adjusted Risk Rating (“ARR”) system that considers certain attributes that represent impact to the Company, and we prioritize our actions based on our ARR system. Our cybersecurity risk assessment program provides the underlying basis for the activities our Cybersecurity and Global Risk & Integrity departments take to identify and mitigate risks from, as well as develop risk management and response strategies for, evolving and emerging cybersecurity threats.
In addition, we also regularly perform phishing tests on our employees and review our training plan at least annually for appropriate updates to address results from this testing. Further, we are focused on building and maintaining a positive cybersecurity culture through a combination of trainings, educational tools, videos, and other cybersecurity awareness initiatives. On top of annual information security awareness training for our employees, we also provide focused training for certain departments. Our security training incorporates awareness of cyber threats (including malware, ransomware, and social engineering attacks), password hygiene, and incident reporting process, as well as physical security best practices.
We engage in the periodic assessment of our policies, standards, processes, and practices that are designed to address cybersecurity threats and incidents, internally and through assessments by external providers. These efforts include a wide range of activities, including audits, assessments, tabletop exercises, threat modeling, vulnerability testing, penetration testing, and other exercises focused on evaluating the effectiveness of our cybersecurity measures and planning. Assessments by external providers of our cybersecurity measures include information security maturity assessments, audits, and independent reviews of our information security control environment and operating effectiveness. The results of such internal and external assessments, audits, and reviews are reported to the Audit Committee and the Board of Directors, and we adjust our cybersecurity policies, standards, processes, and practices as necessary based on the information provided by these assessments, audits, and reviews.

ESG Priority Topics
In 2022, we conducted our first ESG Priority Assessment, one of the resources that guides our overall ESG strategy. The ESG Priority Assessment was designed to identify the environmental, social and governance topics with the greatest impact on our business strategy, operations and value creation. Through this process, we identified a list of 33 relevant ESG issues and opportunities that were consolidated into 12 ESG topics using the outputs from our business analysis, peer benchmarking and review of stockholder priorities. To prioritize the independence12 ESG topics and conduct an inventory of recently completed and ongoing workstreams, we engaged with members of our leadership team and internal technical specialists closest to the relevant issues and opportunities. Using questionnaires and targeted interviews, we collected data on the relative importance of the ESG topics and their potential impacts on our business and success. As risks change over time, we will review and refresh our priority assessment regularly to keep track of evolving ESG priorities and support program relevance and effectiveness. ESG priority topics identified included the following:
Access and Affordability
Access and affordability are high priority ESG topics for the life sciences industry. As a leading digital healthcare company, our vision is to provide better health for all, and we work to ensure fair pricing practices given our customer base while we find and realize new opportunities associated with expanded access to health care. We aim to provide the best clinical care to the patient, irrespective of their ability to pay. We are dedicated to helping patients get the care they need and have demonstrated a commitment to providing financial support for those patients who need it.
Human Capital Management and Diversity, Equity and Inclusion
At iRhythm, the growth and success of our employees is a top priority, as it impacts our performance as a digital healthcare company and our ability to redefine the way cardiac arrhythmias are clinically diagnosed. We are committed to an inclusive and representative culture. We recognize, celebrate and leverage a diversity of ideas, skills and experiences, and this approach defines how we build our teams, cultivate leaders, and create an inclusive environment where each employee can bring their full self to work.

Sustainability
We recognize that environmental sustainability is integral to producing world-class products, and we see environmental sustainability and efficiency as important sources of value creation at iRhythm. Having a strong sustainability program in place is important to meet the growing expectations of our stakeholders, including patients, providers and stockholders. And we see our sustainability strategy as a key cost saving initiative, where reductions in the amount of materials used in our products, improvements in the energy efficiency of our products and expanding circularity measures at the end of our product lifecycle help to improve our bottom line.
Our sustainability strategy covers our own operational footprint, including our limited use of energy and water, efforts to minimize the amount of waste generated and managing climate-related risks and greenhouse gas emissions.

CommunicationsCybersecurity and Privacy Risk Oversight
Cybersecurity is an important part of our risk management at iRhythm. Our cybersecurity program includes mitigating risks for our company and for other companies that may have access to our data and systems. Our Board of Directors recognizes the critical importance of maintaining the trust and confidence of our customers, clients, business partners, and employees. The cybersecurity and privacy risk oversight responsibility of our Board of Directors and its committees is supported by our cybersecurity management reporting processes, which are designed to provide visibility to our Board of Directors and to our personnel that are responsible for risk assessment and information about the identification, assessment, and management of critical risks and management’s risk mitigation strategies. These areas of focus include risks from cybersecurity threats as well as competitive, economic, operational, financial, legal, regulatory, privacy, compliance, and reputational risks, among others. We understand that our customers, patients, and stakeholders entrust us with sensitive data, including Protected Health Information, and we take this responsibility seriously.
Our Board of Directors has an important role in the oversight of the company’s cybersecurity risk management and strategy and has delegated certain components of such oversight related to the security of and risks related to computerized information and technology systems across the company, as well as by risk area (including privacy, data security, and cybersecurity matters), to the Audit Committee, which regularly interacts with our Vice President of Cybersecurity (“VP of Cybersecurity”) and Chief Risk Officer (“CRO”). We also regularly engage external parties to assist in the review of our cybersecurity risk oversight processes.
We have established policies to govern the security of our systems and the protection of customer and patient data, which include regular system updates and patches, employee training on cybersecurity and HIPAA best practices, incident reporting, and the use of encryption to secure sensitive information. Our Cybersecurity department, which reports to our VP of Cybersecurity, is responsible for our cybersecurity program and our Global Risk & Integrity department, which reports to our CRO, is responsible for our privacy program as further discussed below. To identify, assess, and manage material cybersecurity risks, our Cybersecurity team uses a cybersecurity risk assessment process aligned with leading frameworks such as the National Institute of Standards and Technology’s (“NIST”) Cybersecurity Framework and HIPAA. To ensure appropriate and consistent risk evaluation and decision-making processes among our Cybersecurity and Global Risk & Integrity departments, we utilize an Adjusted Risk Rating (“ARR”) system that considers certain attributes that represent impact to the Company, and we prioritize our actions based on our ARR system. Our cybersecurity risk assessment program provides the underlying basis for the activities our Cybersecurity and Global Risk & Integrity departments take to identify and mitigate risks from, as well as develop risk management and response strategies for, evolving and emerging cybersecurity threats.
In addition, we also regularly perform phishing tests on our employees and review our training plan at least annually for appropriate updates to address results from this testing. Further, we are focused on building and maintaining a positive cybersecurity culture through a combination of trainings, educational tools, videos, and other cybersecurity awareness initiatives. On top of annual information security awareness training for our employees, we also provide focused training for certain departments. Our security training incorporates awareness of cyber threats (including malware, ransomware, and social engineering attacks), password hygiene, and incident reporting process, as well as physical security best practices.
We engage in the periodic assessment of our policies, standards, processes, and practices that are designed to address cybersecurity threats and incidents, internally and through assessments by external providers. These efforts include a wide range of activities, including audits, assessments, tabletop exercises, threat modeling, vulnerability testing, penetration testing, and other exercises focused on evaluating the effectiveness of our cybersecurity measures and planning. Assessments by external providers of our cybersecurity measures include information security maturity assessments, audits, and independent reviews of our information security control environment and operating effectiveness. The results of such internal and external assessments, audits, and reviews are reported to the Audit Committee and the Board of Directors, and we adjust our cybersecurity policies, standards, processes, and practices as necessary based on the information provided by these assessments, audits, and reviews.

iRhythm’s Approach to Environment, Social and Governance (“ESG”) Matters
At iRhythm, corporate responsibilitywe believe that effectively managing ESG risks and opportunities drives business success, and that when fully integrated into the business, ESG can provide a competitive advantage. In 2023, we established formal board oversight of ESG by revising the charters of two committees of the Board of Directors—the Nominating and Corporate Governance Committee and the Compensation and Human Capital Management Committee. We continue to work as an organization to advance our strategic ESG roadmap by pursuing key ESG work streams.

ESG Priority Topics
In 2022, we serve. Whileconducted our first ESG Priority Assessment, one of the COVID-19 pandemic has stressedresources that guides our global health community, we have responded by developing solutionsoverall ESG strategy. The ESG Priority Assessment was designed to meet our customers’ and patients’ needs while maintaining our commitment to ethicalidentify the environmental, social and governance practices.

We are committed to delivering uninterrupted patient care for both Zio XTvalue creation. Through this process, we identified a list of 33 relevant ESG issues and Zio AT,opportunities that were consolidated into 12 ESG topics using the outputs from our business analysis, peer benchmarking and this has included supporting efforts to monitor COVID-19 patients. While hospital systemsreview of stockholder priorities. To prioritize the 12 ESG topics and healthcare facilities shifted their focusconduct an inventory of recently completed and resources to treating COVID-19 patients and combating the spread of COVID-19,ongoing workstreams, we adapted our service to meet the immediate needsengaged with members of our physician customersleadership team and patients. Our digital service platform enables physician ordering, results reporting, data curation and patient support independent of location, across virtual or in-office care models.
As an example, we have significantly increased the utilization of our “Home Enrollment” service. This service allows patients to receive and wear the single-use Zio monitor without going to a healthcare facility. Physicians can prescribe the Zio service for their patients, either in-office or through a virtual care setting, and we ship the Zio monitor directlyinternal technical specialists closest to the patient’s residence. We pay forrelevant issues and opportunities. Using questionnaires and targeted interviews, we collected data on the costs of shipping the Zio monitor, which represents additional expense for us. We also guide patients through the patch application process and inform them of instructions for wear. Home enrollment also eliminates clinical staff exposure to patients, as

well as application, cleaning or reusing traditional Holter and event monitors that may have been exposed to viruses or other pathogens.
iRhythm’s strategy throughout its history has been to deliver a safe and repeatable platform, which will help save the lives of patients. iRhythm is a CMS-certified Medicare Independent Diagnostic Testing Facility ("IDTF"), where data captured by the Zio monitor is analyzed. iRhythm offers uniform retail pricing (i.e., billed charges) for its services across the U.S. iRhythm’s pricing recognizes the clinical valuerelative importance of the service providedESG topics and their potential impacts on our business and success. As risks change over time, we will review and refresh our priority assessment regularly to patients, physicians,keep track of evolving ESG priorities and support program relevance and effectiveness. ESG priority topics identified included the overall healthcare system. And iRhythm’s pricing policy is designed to support innovationfollowing:
Access and delivery of industry-leading arrhythmia diagnostics.Affordability
Patient accessibilityAccess and affordability are important to iRhythm. iRhythm continually engages with government and private payers regarding the clinical value of the Zio service, and Zio is covered by all major commercial insurance providers in the U.S as well as Medicare. As of 2021 year end, over 95% of patients in the U.S. are able to access reimbursed Zio services through our third-party payer contracts, our IDTF participation status with CMS, and self-pay programs when excluding state Medicaid programs. In instances where health insurance payment sources are unavailable or only partial coverage is present, iRhythm offers alternative payment options (such as interest-free payment plans) and additional resources to manage their payment responsibility (for example, through payment assistance programs). iRhythm has a Patient Financial Navigation Team to help patients review specific plan benefits, provide estimated out-of-pocket costshigh priority ESG topics for the Zio service,life sciences industry. As a leading digital healthcare company, our vision is to provide better health for all, and discuss available payment programswe work to ensure patients can affordfair pricing practices given our customer base while we find and realize new opportunities associated with expanded access to health care. We aim to provide the Zio service.best clinical care to the patient, irrespective of their ability to pay. We are dedicated to helping patients get the care they need and have demonstrated a commitment to providing financial support for those patients who need it.
TalentHuman Capital Management and Workplace ExperienceDiversity, Equity and Inclusion
At iRhythm, we are focused on maintaining a healthy, safe, and secure work environment that protects our employees and the public from harm. We use a multi-faceted approach to ensure the health and safety of our employees, from our Code of Conduct to our policies governing the way we act within and outside of iRhythm.
Although the COVID-19 pandemic has disrupted how and where we work, our employees have demonstrated ongoing resilience. Following recommendations from federal and local government and healthcare agencies, we transitioned employees to a remote work environment beginning in early March 2020. For a small number of our employees who supported essential operations at our facilities, we instituted social distancing and other measures to ensure the safety of our employees. We rapidly implemented business continuity protocols and were able to transition to a remote operating environment while continuing to deliver our Zio service. During 2021, employees continued to effectively navigate strict safety protocols for those working onsite, primarily in manufacturing, and the majority of our employees were not required to be onsite and worked from home.
Diversity, Equity & Inclusion
We believe in the richness and quality of a working environment that is informed by people from all walks of life and strive to create a genuinely inclusive environment. We are proud that, overall, our workforce is more than 60% female and greater than 50% of employees are ethnically diverse. To further build on our commitment to diversity, equity and inclusion, we have formed a Diversity Council of representatives from across our company that is working to coordinate efforts as we define our corporate strategy. In addition, we have an active Employee Resource Group (“ERG”) with plans to increase the number of ERGs to reflect the diversity of our workforce, and we are building external partnerships to expand the diversity of our talent outreach. We value our differences, recognizing that from those differences comes our strengths, and we are committed to continuing to build a culture of diversity, equity, and inclusion.

Total Rewards
We offer an attractive mix of compensation and benefit plans to support our employees and their families’ physical, mental, and financial well-being. We believe that we employ a fair and merit-based total compensation system - we evaluate our compensation programs to ensure our employees are compensated fairly for the important work they do and we reward outstanding performance. We are also committed to achieving internal pay equity.
We offer our employees competitive benefits that follow local standards and support physical, mental and financial wellness. In support of employee wellness, we provide a variety of benefits options, resources, programs, online tools and regular webinars. We generally offer to full time employees globally health benefits, a retirement plan, paid time off and family leave, an Employee Stock Purchase Plan (“ESPP”), and an employee assistance program that is available to employees and their families with a variety of support services.
It is important that all employees have an opportunity to have an ownership interest in our company, and there are several programs that provide the ability to own our stock. Generally, more than 75% of our employees participates in at least one of our stock programs. During their tenure with our company, all employees have an opportunity to receive an equity award, either upon hire and/or during an annual review process to recognize those with significant impact on achieving our goals. Another program offered to all employees, whether part or full time, is the ability to participate in our ESPP. Participants in the ESPP may purchase our stock at a 15% discount to market price. We believe our discounted stock purchase program helps to build an ownership mentality amongst participating employees.
Workforce Development
The growth and success of our employees is a top priority, as it impacts our overallperformance as a digital healthcare company performance.and our ability to redefine the way cardiac arrhythmias are clinically diagnosed. We are investing heavilycommitted to an inclusive and representative culture.

Responsible Operations
Manufacturing and Supply Chain Sustainability
We manufacturerecognize that environmental sustainability is integral to producing world-class products, and we see environmental sustainability and efficiency as important sources of value creation at iRhythm. Having a strong sustainability program in place is important to meet the growing expectations of our ambulatory cardiac monitors, Zio XTstakeholders, including patients, providers and Zio AT,stockholders. And we see our sustainability strategy as a key cost saving initiative, where reductions in the amount of materials used in our leased facilities in Cypress, California. This 68,933 square foot facility provides space for our assembly and production operations, including packaging, storage and shipping. We believe our manufacturing facilities will be sufficient to meet our manufacturing needs beyond the next seven yearsproducts, improvements in the US.energy efficiency of our products and expanding circularity measures at the end of our product lifecycle help to improve our bottom line.
Our manufacturing operations are subjectsustainability strategy covers our own operational footprint, including our limited use of energy and water, efforts to regulatory requirementsminimize the amount of the FDA’s Quality System Regulation (“QSR”) for medical devices sold in the United States, set forth at 21 CFR part 820, the Medical Devices Directive 93/42/EEC (“MDD”)waste generated and the Medical Device Regulations 2017/745 of the European Parliamentmanaging climate-related risks and of the Council (“MDR”), which is required for doing business in the European Union (“EU”), and the UK Medical Device Regulations 2002 (as amended) (“UK MDR”). We are also subject to applicable requirements relating to the environment, waste management and health and safety matters, including measures relating to the release, use, storage, treatment, transportation, discharge, disposal, sale, labeling, collection, recycling, treatment and remediation of hazardous substances.
Our quality control management programs have earned us a number of quality-related designations. Our manufacturing facilities have received EN ISO 13485:2016 certification. The NSAI most recently conducted an ISO 13485 surveillance audit in 2021 and a renewed ISO certification was received in August 2021. We have been an FDA-registered medical device manufacturer since 2008 and have been a California-licensed medical device manufacturer since 2009. The most recent FDA inspection of our manufacturing facility occurred in October 2021, and no FDA Form 483 observations resulted. The FDA also performed a Remote Regulatory Assessment (“RRA”) of our design facilities in San Francisco, California, which concluded in May 2021.
iRhythm’s supplier selection is based on business fit along with the expectation that each supplier has adopted and operates to lawful and fair business practices. We expect our suppliers to operate with the highest degree of business ethics - including compliance with applicable laws and regulatory requirements in the municipalities in which they operate - and to operate with safe and healthy working environments. iRhythm reviews each supplier on a semi-annual basis and all of our direct suppliers are expected to adhere to our Global Supplier Code of Conduct.
Environmental Stewardship
iRhythm has also, from its founding, held a commitment to being a responsible steward to the environment.greenhouse gas emissions. As the leading provider of single-use cardiac diagnostic devices, this principally takes the form of maximizing the amount of material recycled from our devices. Our responsibilitysustainability strategy also includes efforts to minimize the environmental impact through innovative design that enables the safe and effective reuse of printed circuit boards, the most environmentally impactful component of our devices. Our business model is oriented around the reuse and recycling of the Zio Patch to collect and gather patient information. We have several active recycling programs and look to minimize our environmental footprint as efficiently as possible.
As a digital health company, we believe the remainder of our environmental impact is modest. iRhythm’s overall environmental impact is mainly driven by manufacturing, with the most relevant metric being electricity usage. Our facilities footprint consists of five office locations in the US and UK, the largest of which is our San Francisco, CA headquarters, which is part of a LEED-Gold certified building. We do not require significant energy consumption to support business operations.

Stock Ownership Guidelines
We have adopted stock ownership guidelines for our non-employee directors, our Chief Executive Officer and other executive officers to help ensure that they each maintain an equity stake in the Company and, by doing so, appropriately link their interests with those of our stockholders. The guideline for non-employee directors is for each director to hold a number of shares of our stock with an aggregate value equal to at least three times the value of his or her annual cash retainer fees for service on the Board of Directors. The guideline for the Chief Executive Officer is to hold a number of shares of our stock with an aggregate value equal to at least three times the value of his or her annual base salary (not including incentive compensation) and for our other executive officers, is to hold a number of shares of our stock with an aggregate value equal to at least two times the value of his or her annual base salary (not including incentive compensation). Non-employee directors and the Chief Executive Officer are expected to achieve these ownership levels within the later of (i) December 31, 2023 and (ii) five years from the date the applicable individual becomes a non-employee director or the Chief Executive Officer (whether through being newly hired or promoted).
Risk Management
Risk is inherent with every business, and we face a number of risks, including strategic, financial, business and operational, political, regulatory, legal and compliance, and reputational. We have designed and implemented processes to manage risk in our operations. Management is responsible for the day-to-day management of risks that we face, while our Board of Directors, as a whole and assisted by its committees, has responsibility for the oversight of risk management. In its risk oversight role, our Board of Directors has the responsibility to satisfy itself that the risk management processes designed and implemented by management are appropriate and functioning as designed.PROPOSAL NO. 1 ELECTION OF DIRECTORS
Our Board of Directors believes that open communication between management and our Board of Directors is essential for effective risk management and oversight. Our Board of Directors meets with our Chief Executive Officer and other members of the senior management team at quarterly meetings of our Board of Directors, where, among other topics, they discuss strategy and risks facing the Company, as well as at such other times as they deem appropriate.
While our Board of Directors is ultimately responsible for risk oversight, our Board committees assist our Board of Directors in fulfilling its oversight responsibilities in certain areas of risk. Our Audit Committee assists our Board of Directors in fulfilling its oversight responsibilities with respect to risk management in the areas of internal control over financial reporting and disclosure controls and procedures and legal and regulatory compliance, and discusses with management and the independent auditor guidelines and policies with respect to risk assessment and risk management. Our Audit Committee also reviews our major financial risk exposures and the steps management has taken to monitor and control these exposures. Our Audit Committee also monitors certain key risks on a regular basis throughout the fiscal year, such as risk associated with internal control over financial reporting and liquidity risk. Our Nominating and Corporate Governance Committee assists our Board of Directors in fulfilling its oversight responsibilities with respect to the management of risk associated with board organization, membership and structure, and corporate governance. Our Compensation and Talent Management Committee assesses risks created by the incentives inherent in our compensation policies. Finally, our full Board of Directors reviews strategic and operational risk in the context of reports from the management team, receives reports on all significant committee activities at each regular meeting, and evaluates the risks inherent in significant transactions.

PROPOSAL NO. 3 ADVISORY VOTE ON THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS
In accordance with the SEC’s rules of the SEC, we are providing stockholders with an opportunity to make a non-binding, advisory vote on the compensation of our NEOs. This non-binding advisory vote is commonly referred to as a “say on pay” vote and gives our stockholders the opportunity to express their views on our NEOs’ compensation as a whole. This vote is not intended to address any specific item of compensation or any specific NEO, but rather the overall compensation of our NEOs and the philosophy, policies, and practices described in this Proxy Statement. This “say on pay” vote is conducted on an annual basis.
Stockholders are urged to read the section titled “Executive Compensation,” which discusses how our executive compensation policies and procedures implement our compensation philosophy and contains tabular information and narrative discussion about the compensation of our NEOs. Our Compensation and Human Capital Management Committee and Board of Directors believe that these policies and procedures are effective in implementing our compensation philosophy and in achieving our goals. Accordingly, we ask our stockholders to vote “FOR” the following resolution at the Annual Meeting:
“RESOLVED, that our stockholders approve, on a non-binding advisory basis, the compensation of the NEOs, as disclosed in the Proxy Statement pursuant to Item 402 of Regulation S-K, including the Compensation Discussion and Analysis, the compensation tables and narrative discussion and the other related disclosures.”
As an advisory vote, this proposal is not binding. However, our Board of Directors and Compensation and Human Capital Management Committee, which is responsible for designing and administering our executive compensation program, value the opinions expressed by stockholders in their vote on this proposal and will consider the outcome of the vote when making future compensation decisions for our NEOs.

Vote Required
The approval, on an advisory basis, of the compensation of our NEOs requires the majority of the shares of our common stock present in attendance or by proxy at the virtual Annual Meeting and entitled to vote thereon vote for approval. Abstentions are considered votes present and entitled to vote on this proposal, and thus, will have the same effect as a vote “against” the proposal. Broker non-votes will have no effect on the outcome of this proposal.
OUR BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE “FOR” THE APPROVAL, ON A NON-BINDING ADVISORY BASIS, OF THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS.

PROPOSAL NO. 4 APPROVAL OF AN AMENDMENT TO OUR AMENDED AND RESTATED CERTIFICATE OF INCORPORATION
Section 102(b)(7) of the DGCL was amended effective August 1, 2022 to authorize exculpation of officers of Delaware corporations. Specifically, the amendment permits Delaware corporations to exculpate their officers, in addition to their directors, for personal liability for breach of the duty of care in certain actions. This exculpation would not protect officers from liability for breach of the duty of loyalty, acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law, or any transaction in which the officer derived an improper personal benefit. Nor would this exculpation shield such officers from liability for claims brought by or in the right of the corporation, such as derivative claims.
Our Board of Directors believes it is necessary to provide protection to officers to the fullest extent permitted by law in order to attract and retain highly qualified senior leadership. The nature of the role of directors and officers often requires them to make decisions on crucial matters often in time-sensitive situations, which can create substantial risk of investigations, claims, actions, suits or proceedings seeking to impose liability on the basis of hindsight, especially in the current litigious environment and regardless of merit. Limiting concern about personal risk would empower both directors and officers to best exercise their business judgment in furtherance of stockholder interests. We expect competitor companies will likely adopt exculpation clauses that limit the personal liability of officers in their charters and failing to adopt the amendment could negatively affect our ability to recruit and retain high-caliber officer candidates.
The proposed amendment is not being proposed in response to any specific resignation, threat of resignation or refusal to serve by any director or officer. This protection has long been afforded to directors, and our Board of Directors believes that extending similar exculpation to its officers is fair and in the best interests of the company and its stockholders. Accordingly, our Board of Directors has unanimously approved the Certificate of Amendment to our Amended and Restated Certificate of Incorporation (the “Certificate of Amendment”) in the form attached hereto as Appendix A, and recommends that our stockholders vote “FOR” the proposed amendment.
Vote Required
The affirmative vote of the holders of a majority of the voting power of all of the outstanding shares of our capital stock entitled to vote at the annual meeting is required to approve the Certificate of Amendment. Shares that are voted “ABSTAIN” are treated as the same as voting “AGAINST” this proposal.
If our stockholders approve the Certificate of Amendment, our Board of Directors has authorized our officers to file the Certificate of Amendment with the Delaware Secretary of State, to become effective upon acceptance by the Delaware Secretary of State. Our Board of Directors intends to have that filing made if, and as soon as practicable after, this proposal is approved at this Annual Meeting. However, even if our stockholders adopt the Certificate of Amendment, the Board of Directors may abandon the Certificate of Amendment without further stockholder action prior to the effectiveness of the filing of the Certificate of Amendment with the Delaware Secretary of State and, if abandoned, the Certificate of Amendment will not become effective. If the Board of Directors abandons the Certificate of Amendment, it will publicly disclose that fact and the reason for its determination.
If this proposal is not approved by our stockholders, or if our Board of Directors abandons the Certificate of Amendment, then the Certificate of Amendment will not be adopted and the current Amended and Restated Certificate of Incorporation will remain in place.
OUR BOARD OF DIRECTORS RECOMMENDS A VOTE “FOR” THE APPROVAL OF THE AMENDMENT TO OUR AMENDED AND RESTATED CERTIFICATE OF INCORPORATION TO LIMIT THE LIABILITY OF CERTAIN OF OUR OFFICERS.

39


PROPOSAL NO. 5 ADVISORY VOTE ON THE FREQUENCY OF FUTURE ADVISORY VOTES ON THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS
Under Section 14A of the Exchange Act, at least every six years the company’s stockholders are entitled to cast an advisory vote to indicate the frequency with which we should hold future non-binding votes to approve executive compensation, or to abstain from voting. Our stockholders last voted on such a resolution in 2018 with the majority voting for a frequency of every year (1 year).
We are once again requesting your non-binding vote to determine whether the frequency of the vote to approve the compensation of our NEOs should be every 1 year, 2 years or 3 years. The Board of Directors and the Compensation and Human Capital Management Committee believe that annual advisory votes will allow the Compensation and Human Capital Management Committee, management and our stockholders to continue to engage in a timely, open and meaningful dialogue regarding our executive compensation philosophy, policies and practices.
As an advisory vote, this proposal is not binding. However, our Board of Directors and Compensation and Human Capital Management Committee value the opinions expressed by stockholders in their vote on this proposal and will consider the outcome of the vote when making future decisions regarding the frequency of holding future non-binding advisory votes on the compensation of our NEOs. However, because this is an advisory vote and therefore not binding on our Board of Directors or our company, our Board of Directors may decide that it is in the best interests of our stockholders that we hold an advisory vote on the compensation of our NEOs more or less frequently than the option preferred by our stockholders. The results of the vote will not be construed to create or imply any change or addition to the fiduciary duties of our Board of Directors.
Vote Required
The alternative among 1 year, 2 years, or 3 years that receives the highest number of votes cast from the holders of shares of our common stock present virtually or represented by proxy at the Annual Meeting and entitled to vote thereon will be deemed to be partthe frequency preferred by our stockholders. Abstentions and broker non-votes will have no effect on the outcome of or incorporated by reference by any general statement incorporating by reference this Proxy Statement into any filing under the Securities Act or under the Exchange Act, except to the extent that we specifically incorporate this information by reference, and will not otherwise be deemed “soliciting material” or “filed” under either the Securities Act or the Exchange Act.proposal.

OUR BOARD OF DIRECTORS RECOMMENDS A VOTE TO HOLD FUTURE STOCKHOLDER ADVISORY VOTES ON THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS EVERY “1 YEAR”.

LETTER FROM COMPENSATION AND HUMAN CAPITAL MANAGEMENT COMMITTEE TO OUR STOCKHOLDERS

Dear Fellow Stockholders,
At our most recent investor day, the company articulated its ambitious goal to achieve one billion dollars in revenue by 2027 and defined the strategic pillars to position the company to deliver on this goal. Beginning in 2021, the company underwent a transformational shift focused on strengthening its foundational infrastructure and people to prepare for this long-term growth. Our renewed focus on the strategic pillars included hiring executives with experience in large multi- national companies and proven track records in both execution and growth, restructuring and optimizing our commercial sales force, establishing an enterprise risk function, remediating all outstanding material weaknesses, implementing a global business services center, and improving patient experience functions.

Strategic Pillar.jpg

The early benefits of this shift have already begun to be realized. In 2023, as the company continued to execute successfully on these business and operation growth strategies, we achieved success in key areas such as:
Initiating the largest product launch in company history – a next generation long-term continuous monitoring platform called Zio Monitor – while also enhancing our patient mobile application;
Publishing the CAMELOT study, the first and largest study of its kind demonstrating that Zio XT monitoring is associated with the highest diagnostic yield and lowest likelihood of retesting amongst other ambulatory cardiac monitoring modalities and within the long-term continuous monitoring category; and
Receiving EU CE mark for Zio Monitor in the European Union and being granted the high medical needs designation in Japan.
Although 2023 was a transformational year for the company, we also faced certain unanticipated challenges that could have distracted the teams from important initiatives required to deliver on our long-range plan. We shared that the company received a Subpoena Duces Tecum from the Consumer Protection Branch, Civil Division of the U.S. Department of Justice requesting production of various documents regarding our products and services on April 4, 2023. In addition, on May 25, 2023, iRhythm then received a Warning Letter from the U.S. Food and Drug Administration, which resulted from the FDA’s inspection at our Cypress facility in August 2022. The newly hired management team faced these challenges shortly after joining and it required a renewed focus on operational excellence, a reinvigorated commitment to process improvement, and diligent engagement with the external agencies while staying laser focused on the goals we set for future. The management team stepped up to the challenges and we remain confident that we can mitigate these risks.

44


With this context in mind, we firmly believe that the success of the company and the execution of iRhythm’s business strategy depends upon the leadership, stability, and operational excellence of our management team. To achieve this, we believe that the executive compensation structure must incentivize success within our short- and long-term programs that are directly tied to our financial, operational, and strategic goals. With a predominantly new leadership team in place, each of the NEOs along with other critical employees were granted a special one-time strategic long-term incentive equity award to ensure that the leadership team:
Quickly integrates into the company to create one unified team focused on delivering on the long-term strategy;
Remains focused on, and committed to, the long-term strategic pillars previously laid out;
Continues to be aligned to stockholder interests;
Delivers the company’s goals of growth and patient experience, operational excellence, and accelerating innovation;
Is retained and stable despite unanticipated challenges and headwinds; and
Is rewarded only if meaningful strategic progress is made and stockholder value is created.
Furthermore, we regularly engage with our stockholders to gain feedback on our executive compensation program and have made tangible progress towards further aligning the incentivization of our management team with stockholder interests. In 2023, we advanced this by extending the total stockholder return modifier within our performance-based restricted stock units to all NEOs and not just the CEO.
iRhythm is committed to a pay-for-performance culture that is supported through sound compensation and corporate governance policies that reflect best practices. We also are committed to continuing to engage with our stockholders and to constantly assess and evaluate our programs to ensure they align with our strategic pillars and create stockholder value.
As we look ahead, our strategic plan remains unchanged. iRhythm is fully committed to bringing high quality service to more patients in more locations worldwide, and we believe that this is supported by a compensation program that rewards performance in alignment with stockholders' interests. We thank you for your continued engagement and respectfully request your support for our 2024 Say on Pay proposal.

Sincerely,

The 2023 Strategic PSU Award was granted as part of a larger program in his dual rolewhich other management members also received an award. The objective of this award is to quickly integrate into the company the predominately new leadership team to create one unified team focused on delivering on the long-term strategy; motivate key executives and other key management team members in the organization to deliver on the company’s goals of growth and patient experience, operational excellence, and accelerating innovation, while retaining critical talent despite unanticipated challenges and headwinds.

continued eligibility to participate in our standard benefit plans as in effect from time to time on the same basis as other similarly situated executives.

In addition, Mr. Devine was to continue as a “Tier 2” eligible employee in our Executive Change in Control and Severance Policy. The term of this arrangement, including title and base compensation changes noted above, ended when Mr. Devine ceased to be Interim CEO.

Appointment of Chief Executive Officer – In connection with his appointment as our President and Chief Executive Officer effective October 4, 2021, weentered into an employment offer letter dated September 8, 2021 (the “Blackford Employment Agreement”) with Mr. Blackford. Pursuant to the Blackford Employment Agreement, our compensation arrangements with Mr. Blackford were as follows:

an annual base salary of $650,000;

commencing in 2022, a target annual cash bonus opportunity equal to 100% of his base salary at the time of bonus approval, based on achieving one or more financial and/or other performance objectives established by our Board of
Directors, subject to being prorated for any calendar quarter in which he is not employed for the entire quarter and payable only if he is employed on the date the bonus, if any, is paid;

a one-time signing bonus in the amount of $675,000 (which we believed was equivalent to the bonus he would have earned from his prior employer), payable in a lump sum in 2022 and repayable if his employment is terminated within 24 months of his hire date due to his resignation without “good reason” (as defined in our Executive Change in Control and Severance Policy) or his termination of employment for “cause” (as defined in our Executive Change in Control and Severance Policy), experienced executive team with the repayable amount equalability to the product of (i) the gross amount of the signing bonus multiplied by (ii) a fraction (A) the numerator of which is equal to the difference between (x) 24 minus (y) the number of completed months he has served as our regular, full-time Chief Executive Officer as measured immediately prior to his termination date and (B) the denominator of which is 24;

In addition, upon his employment Mr. Blackford became a “Tier 1” eligible employee in our Executive Change in Control and Severance Policy.

Mr. Blackford forfeited a significant portion of his prior equity awards when he left his former employer, and that fact influenced our decision with respect to the total size of the equity awards he received upon hire, plus the decision to grant him an additional equity award in February of 2022. Pursuant to the Blackford Employment Agreement, it would be recommended to the Compensation Committee and our Board of Directors that, in February 2022, Mr. Blackford receive equity awards with an aggregate grant date value of $5 million, consisting of a PSU award which would vest pursuant to the performance-based metrics established for our management team generally to be set forth in our 2022 PSU incentive program as determined by our Board of Directors in its sole discretion, subject to his continuing employment through each applicable vesting date.

The Blackford Employment Agreement was negotiatedexecute on our behalf by the Compensation Committee and approved by the independent members of the full Board of Directors. In establishing his initial compensation arrangements, we took into consideration the requisite experience and skills that a qualified candidate would need to manage a growing business in a dynamic and ever-changing environment, the competitive market for similar positions at other comparable companies based on a review of compensation survey data and the need to integrate him into the executive compensation structure that we had developed since our initial public offering of our equity securities, balancing both competitive and internal equity considerations.

Pay-for-Performance Philosophy

We view our compensation practices as a tool to align our executive officers, including our Named Executive Officers, with our strategic goals and reward highwhile aligning strong performance, collaboration and accountability. We believe our executive compensation program is reasonable, competitiveaccountability with business results and appropriately balances the goals of attracting, motivating, rewarding and retaining our Named Executive Officers with the goal of aligning their interests with those of our stockholders.
To ensure this alignment and to motivate and reward individual initiative and effort, a substantial portion of our Named Executive Officers’the NEOs’ target total direct compensation is both performance-based and “at-risk.”

In 2021,2023, we emphasized performance-based compensation that appropriately rewards our Named Executive Officers through two separate compensation elements:

The first is the annual cash bonus award that is based on the company’s performance against financial objectives specified at the beginning of the performance year and an evaluation of individual accomplishments and performance during the year.
First, our Named Executive Officers participated in our 2021 Annual Bonus Plan, which provides payments if they produce short-term financial, operational and strategic results that meet or exceed

The second is the key objectives set forth ingrant of PSU awards as part of our annual operating plan.

In addition, we granted PSU awards,equity cycle, which comprise approximately one-half50% of our Named Executive Officers’the NEOs’ annual long-term incentive compensation arrangements (except in the casecompensation. These annual PSUs require our achievement of Mr. Blackford), with the sharesa target goal of our common stock subject to such awards to be earned over a three-year performance period based on our actual results as measured against the target level for growth in our compound annual growth rate in global unit volumes, established for such period.volume over a three-year period, with the resulting achievement modified by our relative shareholder returns or TSR against an industry index.

TheseThe performance-based and variable pay elements ensure that a substantial portion of our Named Executive Officers’the NEOs’ target total direct compensation for 20212023 is contingent (rather than fixed) in nature,“at risk”, with the amounts ultimately payable subject to variability above or below granttarget levels commensurate with ourthe company’s actual performance. Specifically, 94%approximately 90% of Mr. Blackford’sthe CEO’s and 84% of the other NEOs’ annual compensation is variable or at risk, while 77% of our other incumbent Named Executive Officers’ compensation is variable or at risk.

Variable Pay_1.jpgVariable Pay_2.jpg



We believe that our compensation design provides balanced incentives for our Named Executive Officers to meet our business objectives and drive our long-term growth. To ensure we remain faithfulongoing alignment to ourthe compensation philosophy, the Compensation Committee regularlyalso periodically evaluates the relationship between the reported values of the equity awards granted to our executive officers, and the amount of compensation realizable (and, ultimately, realized) from such awards in subsequent years and corresponding company performance over thisthe same period.


Executive Compensation Philosophy
Our overarching compensation philosophy is focused to achieve the following primary objectives:
enable the attraction and retention of high-caliber executive talent;
directly link rewards to the achievement of key financial, operational, and strategic results that build long-term stockholder value; and
recognize individual performance by linking rewards to individual achievements in addition to measurable corporate results.
To achieve our compensation philosophy, our current practice is to combine a mixture of compensation elements that balance achievement of our short-term goals with our long-term performance. We provide short-term incentive compensation opportunities in the form of an annual cash bonus plan, which focus on our yearly operating results, and long- term incentive compensation opportunities are provided in the form of equity awards.
While we do not have a specific policy on the allocation between short-term and long-term compensation elements, the majority of the NEOs’ compensation is delivered in long-term equity-based compensation. While the pay mix may vary from year to year, the overarching goal is to achieve our compensation objectives and ensure that a meaningful percentage of total compensation is tied to long-term performance.

Executive Compensation Policies and Practices

We endeavor to maintain and operate under sound corporate governance standards consistentto best serve our stockholders and be aligned with ourexternal industry expectations, while also incorporating certain “best practices” in executive compensation policies and practices.compensation. The Compensation Committee evaluates our executive compensation program on a regular basis to ensure that it is consistent with our short-term and long-term goals given the dynamic nature of our business and the market in which we compete for executive talent. The following summarizes our executive compensation and related policies and practices:
What We Do

What We Don’t Do
Maintain an Independent Compensation Committee. The Compensation Committee consists solely of independent directors.
Retain an Independent Compensation Adviser. The Compensation Committee engaged its own compensation adviseran independent consultant to provide information and analysis with its 2021 compensation review, and other adviceadvise on all executive compensation related matters independent of management. In 2021, this compensation advisor did not provide any other services to us.
Annual Executive Compensation Review. The Compensation Committee conducts an annual review and approval of our compensation strategy, including a review and determination of our compensation peer group used for comparative purposes, and a review of our compensation-related risk profile to ensure that our compensation programs do not encourage excessive or inappropriate risk-taking and that the level of risk that they do encourage is not reasonably likely to have a material adverse effect on us.
Compensation At-Risk. Our executive compensation program is designed so that a significant portion of our Named Executive Officers’NEOs’ compensation is “at risk” based onand directly linked to our corporate and stock performance, as well as equity-based to align with the interests of our Named Executive Officers and stockholders.
Use a Pay-for-Performance Philosophy. The majority of our Named Executive Officers’ compensation is directly linked to corporate performance; we also structure their target total direct compensation opportunities with a significant long-term equity component, thereby making a substantial portion of each executive officer’s target total direct compensation dependent upon our stock price and/or total stockholder return.
“Double-Trigger” Change-in-Control Arrangements. Our post-employment compensation arrangements in the event of a change in control of the Companycompany are “double-trigger” arrangements that require both a change in control of the Companycompany plus a qualifying termination of employment before payments and benefits are paid.
Succession Planning. We review the risks associated with our key executive officer positions to ensure adequate succession plans are in development.
Compensation Recovery (“Clawback”) Policyand Misconduct Policies. We have adopted two separate and robust compensation recovery policies applicable to current and certain former executive officers – one is triggered by certain misconduct and one is triggered by an accounting restatement, which is intended to comply with the latest Nasdaq listing rule.
Stock Ownership Guidelines. We have adopted a compensation recovery (“clawback”)robust stock ownership policy which provides that, in the event of misconduct or if we are required to prepare an accounting restatement,for our Board of Directors may recover from current and former executive officers.
Stock Ownership Guidelines. We have adopted policies that require minimum ownership of shares of our common stock by our Chief Executive OfficerNEOs and the non-employee members of our Board of Directors,Directors.
Declined 2023 Equity Incentive Plan Increase. We are committed to responsible management or our equity incentive plan, and which were extendeddecided to not take the evergreen equity refresh provision in 2023 that our other executive officers who are subject to Section 16 of the Securities Exchange Act of 1934 effective January 1, 2022.current plan allows.

No Executive Employment Agreements: We do not maintain employment agreements with any executive including the NEOs.
No Executive Retirement Plans. We do not offer supplemental pension arrangements or retirement plans or arrangements to our NamedNEOs.
Limited Executive Officers that are different from or in addition to those offered to our employees generally.

Limited Perquisites. We do not provide limited perquisites or other personal benefits with an aggregate incremental amount of more than $10,000 to our Named Executive Officers.any NEO.
No Tax ReimbursementsGross-Ups on Perquisites. Perquisites: We do not provide any tax reimbursement payments (including “gross-ups”)gross-ups on any perquisites, or other personal benefits, other than related to standard relocation and corporate housing benefits.

No Special Welfare or Health Benefits. Our Named Executive OfficersNEOs participate in broad-based company-sponsored health and welfare benefits programs on the same basis as our employees generally.

No Post-Employment Tax Payment Reimbursement. We do not provide any tax reimbursement payments (includingincluding “gross-ups”) on any severance or change-in-control payments or benefits.

No Hedging or Pledging of Our Equity Securities. We prohibit our employees, including our executive officers, and the members of our Board of Directors from engaging in certain derivative transactions and from hedging our securities.

No Pledging of Our Equity Securities. We prohibit our employees, including our executive officers,securities, and the members of our Board of Directors from holding our securities in a margin account or pledging our securities as collateral for a loan.

No “Single Trigger” Change-in-Control Arrangements. We do not provide cash severance or automatic vesting of equity awards based solely upon a change in control of the Company.
Stockholder Advisory Vote on Named Executive Compensation


At our 2021 Annual Meeting of Stockholders, we conducted a non-binding stockholder advisory vote on the compensation of our Named Executive Officers (commonly known as a “Say-on-Pay” vote). Approximately 87.9% of the votes cast approved our executive compensation program for 2020. Our Board of DirectorsGovernance and the Compensation Committee consider the result of the Say-on-Pay vote in determining the compensation of our executive officers, including our Named Executive Officers. Based on the level of support for our executive compensation program demonstrated by the result of last year’s Say-on-Pay vote, among other factors, our Board of Directors and the Compensation Committee determined not to implement significant changes to our executive compensation program for 2021.

We value the opinion of our stockholders. Our Board of Directors and the Compensation Committee will continue to consider the result of the Say-on-Pay vote, as well as feedback received throughout the year, when making compensation decisions for our executive officers.

In addition, consistent with the recommendation of our Board of Directors and the preference of our stockholders as reflected in the non-binding stockholder advisory vote on the frequency of future Say-on-Pay votes held at our 2019 Annual Meeting of Stockholders, we intend to hold future Say-on-Pay votes on an annual basis. Accordingly, following the Annual Meeting of Stockholders to which this Proxy Statement relates, our next Say-on-Pay vote will be conducted at our 2022 Annual Meeting of Stockholders.
Executive Compensation Philosophy and Program Design
Executive Compensation Philosophy
Our overarching compensation philosophy is highly focused on rewarding individual performance while ensuring alignment of top performers to current market practices. Consistent with this philosophy, we have designed our executive compensation program to achieve the following primary objectives:

enable the attraction and retention of high-caliber executive talent;

directly link rewards to the achievement of key financial, operational and strategic results that build long-term stockholder value; and

recognize individual performance by linking rewards to individual achievements in addition to measurable corporate results.
Executive Compensation Program Design

Consistent with our compensation philosophy, our current practice is to combine a mixture of compensation elements that balance achievement of our short-term goals with our long-term performance. We provide short-term incentive compensation opportunities in the form of an annual cash bonus plan, which focuses on our yearly operating results, and long-term incentive compensation opportunities are provided in the form of equity awards, including:

PSU awards that may be earned over a multi-year performance period based on our actual results as measured against the target established for such period; and

We do not have a specific policy on the percentage allocation between short-term and long-term compensation elements. While the pay mix may vary from year to year, the ultimate goal is to achieve our compensation objectives as described above and ensure a meaningful percentage of total compensation is tied to long term performance.

Competitive Positioning
Market Comparators
For purposesthe purpose of comparing the executive compensation of our executive compensationofficers against the competitive market, the Compensation Committee reviews and considers the compensation levels and practices of a group of peer companies. ThisThe Committee reviews the peer group at least annually and adjusts its composition if warranted, considering changes in the Company’s business profile and the business profile of the peer companies. The compensation peer group consists of life sciencesselection process considers companies that are similar to us in terms ofiRhythm based on multiple parameters such as industry sector, revenue, market capitalization, stage of development, geographical location and number of employees.

In July 2020,August 2022, the Compensation Committee withreviewed and updated the assistance of Compensia, updated our compensation peer group for use in 2023 compensation planning to reflect changes in our market capitalization,the Company’s financial profile to recognize ourthe evolving business focus and to account for merger and acquisition activity. In evaluatingactivity among the peer companies. During this annual review, the Committee evaluated the companies comprising the compensation peer group Compensia consideredbased on the following criteria:

companies within a similar market capitalization range, approximately one-third to approximately three times our then-estimated market capitalization of $3.2 billion.

The Compensation Committee made several changes to our peer group in August 2020, removing four companies and adding three new companies. AxoGen, Inogen, Intersect ENT and Teladoc Health were removed from our peer group, as their market capitalizations were outside our range. 10x Genomics, Guardant Health and Inspire Medical Systems were all added to the peer group on the basis of their similarity to us in size, market capitalization and industry sector.

Based on a review of the analysis prepared by Compensia, the Compensation Committee approved a revised peer group in August 2020 that was used by the Compensation Committee during much of 2021 as a reference for understanding the competitive market for executive positions in our industry sector. The peer group consisted of the following companies:

In August 2021, the Compensation Committee, with the assistance of Compensia, reviewed and updated our compensation peer group for use in 2022 compensation planning. In evaluating the companies comprising the compensation peer group at that time, Compensia considered the following criteria:

publicly-traded companies headquartered in the United States;

biotechnology companies with a medical device product focus, including companies in the healthcare equipment, healthcare services, healthcare supplies, health care technology and life sciences tools and services sectors;

The Compensation Committee uses data drawn from ourthe peer group as well as data drawn from custom cuts of the Radford Global Technology Survey and Global Life Sciences Survey, to evaluate the competitive market when determining the total direct compensation packages for our Named Executive Officers,the NEOs, including base salary, target annual cash incentive awardbonus opportunities and long-term incentive compensation opportunities.compensation. Given ourthe objective of attracting, retaining, motivating and rewarding a superior team of executive officers and employees, wethe aim is to provide a total direct compensation package that is at or above the median ascompetitive compared to the peers, and we emphasizewith a great emphasis on equity incentive compensation to more effectively tie our Named Executive Officers’the NEOs’ and employees’ interests more effectively to those of ourthe stockholders. In light of this, when undertaking its competitive analysis, the
Compensation Committee reviews competitive market data for base salary, total cash compensation (base salary plus annual bonus) and long-term incentive compensation. This competitive analysis is one factor, among others, taken into account by the Compensation Committee in assessing compensation levels and recommending or making changes to compensation or additional awards.

Risk Assessment

Corporate Performance Measures

Participants in the 2021 Annual Bonus Plan were eligible to receive a bonus payment based upon the attainment of one or more corporate performance measures that were established by the Compensation Committee and which related to financial metrics that were important to us. The 2021 Annual Bonus Plan was funded based on our actual results for the year as evaluated against these performance measures.

In February 2021,2023, the Compensation Committee selected two financial performance measures for the 20212023 Annual Bonus Plan, including targets for revenuePlan—Revenue (weighted 75%) and Adjusted EBITDA (weighted 25%). The Compensation Committee believed these performance measures were appropriate because they provided a strong emphasis on growth while managingalso considering the management of expenses, which it believed would most directly influence long-term stockholder value.

For purposes of the 20212023 Annual Bonus Plan:

“Revenue” meant GAAP revenue as reported in our audited financial statements; and

“Adjusted EBITDA” meant standard EBITDA excluding stockexcludes non-cash operating charges for stock-based compensation, expense.

depreciation and amortization as well as non-operating items such as interest income, interest expense, income taxes, impairment and restructuring charges, and business transformation costs.
For each of these performance measures, the Compensation Committee established a target achievement level. TheseEach performance measure was weighted according to the Committee’s assessment of its relative significance related to the successful execution of our annual operating plan.
53


The Committee set the following performance levels, weighting and payout percentages for the two corporate performance measures as follows:
Performance MeasureWeightingThreshold Payout %Target Payout %Maximum Payout %
Revenue75%50%100%200%
Adjusted EBITDA25%50%100%200%
The performance target levels were intended to require significant effort on the part of our Named Executive Officers and, therefore, were set at levels ordinarily difficult to achieve and for which average, or below-average performance would not warrant a bonus payment. Each performance measure was weighted according to the Compensation Committee’s assessment of its relative significance related to the successful execution of our annual operating plan.

Initially, the Compensation Committee set the performance levels, weighting and payout percentages for the two corporate performance measures as follows:

Corporate Performance Measure

The performance target levels for our annual bonus plan are not disclosed because we believe to do so would be competitively harmful, as it would give competitors insight into our strategic and financial planning processes. Our performance measures were set to ensure they were stretch targets for participants that would not pay out below a minimum revenue growth target and would drive positive shareholder return. For actual performance between the threshold and maximum performance levels for the revenueRevenue and Adjusted EBITDA measures, the actual bonus payment with respect to each measure was to be calculated by linear interpolation.Our Compensation The Committee believed the 2021 revenue2023 Revenue and Adjusted EBITDA targets to be challenging but achievable, requiring strong performance from each of our executive officers.

For purposes of the 2021 Annual Bonus Plan, the Compensation Committee also reserved the right to adjust the corporate performance measures based on final 2021 regional Medicare reimbursement adjustments, if any, for the year, whether positive or negative.This provision was included because there had been a negative reimbursement decision three weeks prior to approving our Annual Bonus Plan metrics, and we were working to change it during 2021.

In December 2020, the Centers for Medicare and Medicaid Services (“CMS”) had chosen not to finalize national pricing for four of the eight billing codes that we primarily use to seek reimbursement for Zio XT. For 2021, reimbursement for Zio XT remained at a regional level through Medicare Administrative Contractors (“MACs”). On January 29, 2021, Novitas Solutions, the MAC that covers the region where almost all of our Medicare services for Zio XT are processed, published rates for 2021 that were significantly below our historical Medicare rates for Zio XT. On April 10, 2021, Novitas published an update to rates, an increase from the January 29, 2021 posting, that were retroactive to January 1, 2021. Nonetheless, we still felt these rates didn’treflect the clinical and economic value that long-term continuous ECG monitoring offers patients, their care teams and the Medicare system, and we continued to work with Novitas.

In June of 2021, given the reimbursement uncertainty of the prior months and the recent resignation of Mr. Coyle, we felt it important for retention to provide a clear message to participants on the impact of the published rate changes to our Annual Bonus Plan. On June 24, 2021, after noting that the adjustments were within the parameters of the 2021 Annual Bonus Plan, the Compensation Committee approved adjustments to the corporate performance measures based on a revised annual budget to reflect the Novitas reimbursement changes published on April 10, 2021. The revenue metric was adjusted down by 15% and the Adjusted EBITDA metric was adjusted down by 20.5%.

Quentin Blackford, President, Chief Executive Officer and Director
Overall: Throughout 2023, although we saw unanticipated activities related to the DOJ subpoena and FDA Warning Letter, we maintained a clear vision for the organization with a focus on regaining momentum in the core business. In tandem, we elevated the focus on innovation and sustainability of our future business. We gained ground with our share of the long-term cardiac monitoring market (from ~68% to ~70%), reaccelerated growth in our existing customer channels (approximately 70% of unit growth year-over-year came from existing accounts versus approximately 50% in the prior year), expanded deeper into the primary care channel, and established reimbursement rates with government payers on a national level. In 2023, we achieved full-year revenue of $492.7 million, or 20% year-over-year growth, meaningfully improved our adjusted EBITDA profile by 180 basis points, and our share price improved by nearly 15% for the full year placing us in the top quartile of our peer group.
Company Culture & Leadership: We continued to build out a strong leadership team, working through transitions early in the year with the Chief Operating Officer and Chief Human Resource Officer roles. In 2023, we also refreshed our company cultural values and renewed investments in our company culture efforts. To ensure strong business continuity plans, we also partnered with the Board of Directors on succession planning efforts for the entire executive team.
Patient-Focus: In what was a transformative acceleration in the number of patients using Zio, we began 2023 by crossing the 6 million cumulative patient reports posted and closed the year rapidly approaching 8 million cumulative reports posted. Continuing our strong patient focus, we launched our next generation long-term continuous monitor (the Zio Monitor) and MyZio 2.0 patient mobile app, published the CAMELOT real-world evidence study of Zio XT, and made strong inroads in primary care.
Operational Discipline and Efficiency: We continued our focus on reducing G&A spend and paved new pathways for growing our business, setting us up to serve more patients worldwide. We opened our Global Business Services (GBS) center in Manila where we welcomed approximately 175 new iRhythm team members over the course of 2023. Furthermore, the implementation of an enhanced patient billing experience allowed us to streamline the patient experience, elevate our service to customers, and drive greater efficiency within our revenue cycle operations.

Sales Plan for Mr. Vort

As our Executive Vice President of Sales at the time of determining 2021 bonus targets, Mr. Vort’s annual cash incentive was based on his ability to drive high levels of profitable volume growth. In 2021, Mr. Vort was eligible to earn a cash bonus of up to $307,125 (75% of his 2021 annual base salary). This bonus was to be measured and paid in quarterly installments based on actual performance against his quarterly and annual targets. The performance target levels for Mr. Vort are not disclosed because we believe to do so would be competitively harmful, as it would give competitors insight into our strategic and financial planning processes.

Mr. Vort’s bonus payments were determined on a quarterly basis using volume unit targets for both our Zio XT and Zio AT services, as well as for international unit volume in the United Kingdom. Each target had a weighting and was paid similarly on a pay curve up to 100% of the target. For every one percentage point from 1% up to 100% to target, the payout increased on a sliding scale, ranging from 0.25% to 1.25%. The payment curve declined sharply below plan, where for example, Mr. Vort would earn 50% of his target bonus payment for achievement of 60% of his target. For volume over 100% of his target, Mr. Vort received an accelerating per-unit payout and was uncapped from January through March 2021, and starting in April 2021, payout was capped at 200%.

In 2021, Mr. Vort earned a cash bonus under the 2021 Sales Commission Plan in the amount of $383,906, based on achievement of his 2021 targets. Starting in 2022, Mr. Vort began participating in the Annual Cash Bonus Plan and no longer has a Sales Commission Plan.

Long-Term Incentive Compensation

We viewThe Company uses long-term incentive compensation in the form of equity awards as a critical component of our executiveto incentivize and deliver competitive compensation program.that recognizes executives for their contributions to the Company. The realized value of thesethe equity awards bears a direct relationshipis directly correlated to ourthe stock price,performance, and therefore, these awards are an incentive for our Named Executive Officersthus aligns the interests of NEOs with stockholders by focusing them on long-term growth to create value for stockholders. Equity awards also help us retain qualified
The Committee views long-term incentives as a significant element of total compensation at the executive officers inlevel and a competitive market.

Beginning in 2019, after a reviewcrucial component of competitive market data and an evaluation of ourthe Company’s total rewards program,compensation package. During fiscal 2023, the Compensation Committee approved a change to our mixevaluated all of the foregoing when designing the Company's long-term incentive compensation inprogram structure, as well as the formStrategic PSUs, with input from Aon.
2023 Annual Equity Awards. Based on this evaluation, the Committee determined that an even split of equity awardsPSUs (at target) and RSUs continued to serve the Company well for our executive officers to grant a combination of performance-based restricted stock unit (“PSU”) awards that may be earned and settled for shares of our common stock and time-based restricted stock unit (“RSU”) awards, which the Compensation Committee believes provide additional alignment of the interests of our executive officers with the interests of our stockholders, place greater emphasis on our long-term financial performance and help satisfy our retention objectives. At that time, the Compensation Committee also decided to stop granting equity awards in the form of stock options.

With respect to PSU awards, we believe that such awards serve as an effective source of motivation to our executive officers to drive our financial performance. In addition, PSU awards provide a direct link between compensation and stockholder return, thereby motivating our executive officers to focus on and strive to achieve both our annual and long-term financial and strategic objectives. With respect to RSU awards, we believe that because such awards represent the right to receive shares of our common stock upon settlement and have value even in the absence of stock price appreciation, we are able to incent and retain our executive
officers using fewer shares of our common stock. Since their value increases with any increase in the value of the underlying shares, RSU awards also serve as an incentive which aligns with the long-term interests of our executive officers and stockholders.awards. The Compensation Committee believes that a portfolio of PSU awards and RSU awards appropriately balances the incentive benefits of a performance-based equity award vehicle with the executive retention and stockholder dilution (as compared to stock options) benefits, of RSUs, thereby aligning the interests of our executive officers and stockholders and enabling us to use our equity compensation resources efficiently.

This is a market leading practice for the NEOs other than CEO, as more emphasis is placed on performance-based equity compared to peer and broader market prevalence.
The Committee also evaluated the vesting schedule for each long-term incentive vehicle, taking into consideration current market practices and concluded that the previously adopted vesting period for PSUs and RSUs remained appropriate for annual awards. The PSUs cliff vest after 3 years and the RSUs vest 25% over four years.
2023 Strategic Performance Equity Awards. For the Strategic PSUs, it was determined that the award would be granted entirely in PSUs with a 3-year cliff vest and a maximum of 150% of target units granted.
Generally, long-term incentive compensation opportunities in the form of equity awards are granted to our Chief Executive OfficerCEO by the independent members of our Board of Directors, based on the recommendations of the Compensation Committee, and to our other executive officers, including our other Named Executive Officers,NEOs, by the Compensation Committee.
The amount and form of such equity awards are determined by the Compensation Committee after considering the factors described in “Governance of Executive Compensation Program – Compensation-Setting Process” above. The amounts and relative weighting of the equity awards are intendedgranted to provide competitively-sized awards and resulting target total direct compensation opportunities that the Compensation Committee believes are reasonable and appropriate, taking into consideration the factors described in “Governance of Executive Compensation Program – Compensation-Setting Process” above.

Special Retention Awards

In January 2021, in connection with the start of Mr. Coyle as our new President and Chief Executive Officer, the Compensation Committee approved the grant of special retention PSU awards for certain key employees, including our incumbent Named Executive Officers (other than Mr. Coyle). In making its determinations,NEOs in 2023 are set forth in the “2023 Summary Compensation Committee consideredTable” and the current retention risks and challenges facing us,“2023 Grants of Plan-Based Awards Table” later in the performance of our incumbent Named Executive Officers and a competitive market analysis prepared by Compensia, as well as the other factors described in “Governance of Executive Compensation Program – Compensation-Setting Process” above.

These PSU awards represented the maximum number of units eligible to be earned based on maximum performance, were as follows:

(1) For purposes of these PSU awards, the total number of units subject to the awards was calculated by dividing the value of each PSU award by the 20-day rolling average closing price of our common stock, with a lookback starting on the date of grant.


These PSU awards were subject to a 12-month performance period commencing on January 1, 2021 and ending on December 31, 2021 and were to be earned, if at all, based on our achievement during 2021 of a minimum of 10% growth above our total revenue of $265.2 million for 2020, with the final award to be settled by or before March 15, 2022. Unlike the provision in our Annual Bonus Plan, we did not have any provision to adjust, nor did we adjust at any point, the revenue goal for this PSU award.

On February 15, 2022, the Compensation Committee determined that we had achieved 21.7%growth above our total revenue for 2020, from $265.2 million in 2020 to $322.8 million in 2021, and that the units subject to the PSU awards had been earned. Each unit granted pursuant to the PSU awards represents a contingent right to receive one share of our common stock for each unit earned for the performance period.

Annual RefreshLong-Term Incentive (LTI) Awards

In February 2021,2023, as part of itsthe annual review of ourthe executive compensation program, the Compensation Committee determined consistent with its decision in 2019, that long-term incentive compensation in the form of PSU awards and time-based RSU awards should be granted to our executive officers, including our incumbent Named Executive Officers. The Compensation Committee did not formulate a recommendation for the consideration of the independent members of our Board of Directors with
respect to an equity award for our then-Chief Executive Officer since that had been determined as part of the negotiations of the Coyle Employment Letter in December 2020. Further, the Compensation Committee also determined that, for each executive officer’s 2021 equity award, 50% of the dollar value of the award would be converted to a PSU award, and 50% of the dollar value of the award would be converted to an RSU award.

In addition, in February 2021, the Compensation Committee approved the performance-based PSU awards and the time-based RSU awards for our executive officers, including our incumbent Named Executive Officers. In making its determinations, the Compensation Committee considered the current retention risks and challenges facing us, the performance of our Named Executive Officers and a competitive market analysis prepared by Compensia, as well as the other factors described in “Governance of Executive Compensation Program – Compensation-Setting Process” above.

Subsequently, the independent members of our Board of Directors (with our CEO recusing himself from the approval discussion) approved the weighting of the long-term incentive compensation of our executive officers between PSU awards and RSU awards, the aggregate target value of each executive officer’s long-term incentive compensation, granted long-term incentive

The use of a 20-day average closing price of our common stock (rather than the previous 30-day average closing price) was approved by the Compensation Committee in February 2021is to minimize the variability between the award value approved and the actual number of units granted.

PSU Awards: 2023-2025 Cycle
Differentiation was made among our incumbent Named Executive OfficersThe actual number of PSUs that will be eligible to vest will be determined based on the Compensation Committee’s reviewcompany’s compound annual growth rate of unit volume (“Unit Volume CAGR”) results measured for the competitive market dataperformance period commencing on January 1, 2023 and ending on December 31, 2025, by comparing the unit volume for their respective positions and2022 against the sizeunit volume for 2025 (subject to the NEO’s continued employment through the certification date of such performance results, which certification must be made no later than March 15, 2026). The PSUs earned based on the equity awards previously grantedUnit Volume CAGR will be adjusted based on achievement of TSR versus S&P Healthcare Equipment Select Industry Index for the same three-year performance period. We believe that Unit Volume CAGR is the appropriate internal metric that aligns with our long-range strategic plan, while relative TSR provides the external measurement of our share performance relative to them.broader industry performance.

Long-Term Strategic PSU Award
On August 7, 2023, the Board of Directors, upon recommendation from the Committee, approved a strategic performance-based equity award for certain key employees. The Board of Directors and the Committee believed that broad- based alignment among these key critical talent with respect to several important long term operational objectives was important to achieve the following:
drive achievement of strategic objectives while we transform and scale our business model;
retain critical talent; and
create continuity and stability among our leadership team and motivate the team to collectively achieve strong and sustained performance.
As part of this broader program, all the current incumbent NEOs received performance-based restricted stock unit awards The Strategic PSUs are designed to incentivize significant and sustained performance with vesting only occurring if the Company achieves certain operational goals during the period starting July 1, 2023 and ending June 30, 2026. The PSUs attributable to achieved operational goals are further subject to increase or decrease based on the level of achievement of the Company’s relative TSR performance subject to certain caps.

The time-based RSU awards vest over a four-yearexecutive must continue to provide services to the Company through the later of the date on which the Committee determines achievement of the Strategic PSUs and August 7, 2026.
The Strategic PSUs are 100% performance-based comprised of the following three goals (collectively, the “Operational Goals”) that may be achieved during the performance period, with 25%each Operational Goal representing one-third of the total award value.
i.enhancing the patient experience while significantly increasing patient registrations;
ii.achieving certain adjusted EBITDA as a percentage of revenue goals; and
iii.accelerating new product or service innovations.

Retention PRSU's Strategy.jpgStrategic PRSU Goals.jpg
Additional detail regarding these goals is not disclosed because we strongly believe that it will be competitively harmful, as it would give competitors insight into our long-term operational and financial planning processes.
The number of PSUs eligible to vest is first measured based on achievement of the Operational Goals (the “Earned PSUs”). Achievement of two Operational Goals is “target” level achievement and achievement of three Operational Goals is “maximum” level achievement, in each case subject to adjustment for the company’s relative TSR performance, as described below, provided however that in no event will the Earned PSUs be greater than the “maximum” level of achievement regardless of the level of relative TSR achievement. There is no interpolation for partial achievement of an Operational Goal.
The number of Earned PSUs determined based on achievement of the Operational Goals will then be adjusted by the Company’s relative TSR as compared to the TSR achieved by the companies comprising the S&P Healthcare Equipment Select Industry Index over the performance period.
Upon relative TSR performance of greater than the 75th percentile, the number of Earned PSUs will be adjusted upwards by 25%. However, if all three Operational Goals have been achieved, the Performance Award has already reached its cap and there will be no upward adjustment and no additional PSUs will become earned and vested. Upon relative TSR performance of less than the 33rd percentile, the number of Earned PSUs will be adjusted downward by 25%; however, if all three Operational Goals have been achieved, the number of Earned PSUs will be capped at the “target” level achievement, which is greater than a 25% reduction. There is no interpolation between relative TSR achievement levels.

Employment Arrangements
We have entered into written employment offer letters with Mr. Blackford and each of our incumbent other Named Executive Officers. Each of these letters providescurrent NEOs that provide for “at will” employment, meaning that either we or the Named Executive OfficerNEO may terminate the employment relationship at any time without cause. In addition, each of these letters required the Named Executive Officerexecutive to execute our standard At-Will Employment, Confidential Information, Invention Assignment and Arbitration Agreement.

Each of these employment offer letters entered into prior to September 1, 2019provided for certain initial payments and benefits in the event of certain qualifying terminations of employment, including a qualifying termination of employment in connection with a change in control of the Company. These post-employment compensation arrangements have been superseded by the Change of Control and Severance Agreements and, ultimately, the Executive Change in Control and Severance Policy discussed in “Post-Employment Compensation Arrangements” below.

For detailed descriptions of the employment offer letters of our incumbent Named Executive Officers,NEOs, see “Potential Payments upon Termination or Change in Control” below.


Post-Employment Compensation Arrangements
In August 2020,Post-Employment Compensation Arrangements
We have adopted the Compensation Committee (and, with respect to our then-Chief Executive Officer, the independent members of the full Board of Directors) approved our Executive Change in Control and Severance Policy (the “Policy”“Executive CIC Policy”) (effective as of September 1, 2019), which provides a standardized approach for the receipt of severance and change in control payments and benefits by employees at the level of vice presidentto all Vice Presidents and above, including our NamedNEOs. Under the Executive Officers. Under this approach,CIC Policy, the rights of ourthe executives with respect to the receipt of payments and benefits upon an involuntary termination of employment, including an involuntary termination of employment in connection with a change in control of the Company,company, were established on a uniform basis.

We believe that reasonable and competitive post-employment compensation arrangements are essential to attracting and retaining highly qualified executives. The Committee does not consider the specific amounts payable under these post-employment compensation arrangements, however, when determining the annual compensation of our executive officers, including our NEOs.
The Executive CIC Policy serves several objectives. Itobjectives as it eliminates the need to negotiate post-employment compensation arrangements on a case-by-case basis. It also helps to assure our executives that their post-employment compensation payments and benefits are comparable to those of other executives with similar levels of responsibility and tenure. Further, it acts as an incentive for our executives to remain employed with us and stay focused on their responsibilities during the potential or negotiation of a change-in-control transaction, which preserves ourthe Company value and the potential benefits to be received by ourthe stockholders from the transaction. Finally, this approach supports administrative efficiency because it requires less time and expense to administer than individual agreements.

OurThe post-employment compensation arrangements are designed to provide reasonable compensation to ourthe executives if their employment is terminated under certain circumstances to facilitate their transition to new employment. Further, in some instances we seek to mitigate any potential employer liability and avoid future disputes or litigation by requiring a departing executive to sign a separation and release agreement acceptable to us as a condition to receiving post-employment compensation payments or benefits.

These post-employment compensation arrangements also contain certain specified payments and benefits in the event of an involuntary termination of employment in connection with a change in control of the Company.company. We believe these arrangements align the interests of our Named Executive Officersthe NEOs and ourthe stockholders when considering ourthe long-term future.future of the Company. The primary purpose of these arrangements in the case of a change in control of the Companycompany is to keep ourthe most senior executive officers focused on pursuing all corporate transaction activitytransactions that isare in the best interestsinterest of ourthe stockholders regardless of whether those transactions may result in their own job loss. Reasonable post-acquisition payments and benefits should serve the interests of both the executive officer and our stockholders.

In determining payment and benefit levels under the various circumstances covered by the post-employment compensation arrangements with ourthe executives, the Compensation Committee has drawn a distinction between voluntary terminations of employment without good reason, terminations of employment for cause and involuntary terminations of employment without cause or voluntary terminations of employment for good reason, both in connection with and not involving a change in control of the Company. Payment in the latter circumstances has been deemed appropriate in light of the benefits to us described above, as well as the likelihood that the executive's departure is due, at least in part, to circumstances not within his or her control. In contrast, we believe that payments are not appropriate in the event of a termination of employment for cause or a voluntary termination of employment without good reason because such events often reflect either performance challenges or an affirmative decision by the executive to end his or her relationship with us without fault by the Company.company.

Under the Policy, allAll payments and benefits in the event of a change in control of the Companycompany are payable only if there is a subsequent loss of employment by a Named Executive Officer (a so-called “double-trigger” arrangement). In the case of the acceleration of vesting of outstanding equity awards, we use this double-trigger arrangement to protect against the loss of retention power following a change in control of the Companycompany and to avoid windfalls, both of which could occur if vesting accelerated automatically as a result of the transaction.

Under the Policy, inIn the event of a change in control of the Company,company, to the extent Section 280G or 4999 of the Code is applicable to an executive officer, including a Named Executive Officer,NEO, such individual is entitled to receive either payment of the full amounts specified in the Executive CIC Policy to which he or she is entitled or payment of such lesser amount that does not trigger the excise tax imposed by Section 4999, whichever results in him or her receiving a higher amount after taking into account all federal, state and local income, excise and employment taxes.

61


We do not provide excise tax payments (or “gross-ups”) relating to a change in control of the Companycompany and have no such obligations in place with respect to any of our executive officers, including ourthe incumbent Named Executive Officers.

We believe that reasonable and competitive post-employment compensation arrangements are essential to attracting and retaining highly qualified executives. We further believe that when recruiting executive talent these arrangements are necessary to
offer compensation packages that are competitive. The Compensation Committee does not consider the specific amounts payable under these post-employment compensation arrangements, however, when determining the annual compensation of our executive officers, including our Named Executive Officers.

NEOs. For detailed descriptions of the post-employment compensation arrangements maintained with ourthe incumbent Named Executive Officers,NEOs, as well as an estimate of the potential payments and benefits payable under these arrangements, see “Potential Payments upon Termination or Change in Control” below.
Other Compensation Policies and Practices
We also provide continued equity award vesting for the company’s employees at the level of Senior Vice President and above who terminate employment upon or after satisfying an “age plus required number of years of service” requirement. To be eligible for this benefit, the executive must have at least 70 years of combined age plus years of service with a minimum of 5 years of service, or must be minimum age 55 with minimum 10 years of service. The executive must also provide a 12 month notice period to allow orderly transition of duties. If all requirements are satisfactorily met, then post retirement the executive will continue to vest in all RSUs according to time-based vesting schedule and all PSU awards will be measured based on actual achievement at end of the applicable performance period and the resulting “achieved” PSUs will vest on a prorated basis based on the amount of time served during the performance period. Additionally, this program excludes any RSUs or PSUs granted within the one-year period prior to the executive’s retirement date. None of our NEOs currently meet the age and services requirements.


Equity Award Grant
Potential Payments Upon Termination or Change in Control
Executive CIC Policy

Qualifying Termination in connection with a Change of Control. Under the Executive CIC Policy, if, within the period commencing three months prior to and ending 12 months following a “change of control” (such period, the “Change in Control Period”), we terminate the employment of the applicable employee other than for “cause,” death or “disability,” or the employee resigns for “good reason” (as such terms are defined in the Executive CIC Policy) and, the employee executes an irrevocable separation agreement and release of claims, the employee is entitled to receive:
Wei.a lump sum severance payment equal to the payment of employee’s base salary, at the highest rate in effect during the term of the agreement, for 24 months for Mr. Blackford, and 15 months for Messrs. Bobzien, Murphy, Patterson and Turakhia,
ii.payment of premiums to maintain an Equity Award Grant Policy that governsgroup health insurance continuation benefits pursuant to “COBRA” for the grant of equity awards under our equity incentiveemployee and compensation plan. Among other things, this policy authorizes a committee consisting of our Chief Executive Officer, our Chief Financial Officer and our Chief People Officer to grant certain equity awardsthe employee’s dependents for up to 24 months for Mr. Blackford, and 15 months for Messrs. Bobzien, Murphy, Patterson and Turakhia,
iii.a maximum amountlump sum payment equal to 150% of 700,000 sharestarget bonus in effect for the fiscal year in which termination occurs for Mr. Blackford, and 100% of common stock in the aggregatetarget bonus for Messrs. Bobzien, Murphy, Patterson and Turakhia, and
iv.accelerated vesting as to employees and consultants. The policy does not allow approval of grants to members of this committee, our Chief Executive Officer and executive officers who are direct reports to our Chief Executive Officer or the non-employee members of our Board of Directors.

In addition, the Equity Award Grant Policy:

has clear requirements regarding the dates to approve grants each month, official effective date of grants post-approval and other measures to ensure unbiased and consistent practice is in place;

provides that the committee has authority to approve grants that are within an approved equity grant framework, which is itself reviewed and approved by the Compensation Committee at the beginning of each calendar year based on market and competitive review;

provides that the committee has authority to approve grants as noted above that are for new hire or annual equity awards only; any other awards must be presented to the Compensation Committee and/or our Board of Directors for review and approval; and

provides that the exercise price of all options to purchase shares of common stock and stock appreciation rights covering shares of common stock will not be less than 100% of the fair market valueemployee’s outstanding unvested equity awards (if vesting depends on achievement of performance criteria, then assuming performance criteria has been achieved at target levels unless provided otherwise in the applicable performance-based equity award).
Qualifying Termination outside of a Change of Control. Under the Executive CIC Policy, if we terminate the employment of the applicable employee other than for “cause,” death or “disability,” or the employee resigns for “good reason” outside of the Change in Control Period, and the employee executes an irrevocable separation agreement and release of claims, the employee is entitled to receive:
i.a lump sum severance payment equal to the payment of employee’s base salary, at the highest rate in effect during the term of the agreement, for 18 months for Mr. Blackford, and 12 months for Messrs. Bobzien, Murphy, Patterson and Turakhia; and,
ii.payment of premiums to maintain group health insurance continuation benefits pursuant to “COBRA” for the employee and the employee’s dependents for up to 18 months for Mr. Blackford, and 12 months for Messrs. Bobzien, Murphy, Patterson and Turakhia.

2023 Strategic PSU Awards
In the event of a change in control of the company, the Operational Goals will be deemed achieved at the greater of actual achievement or target achievement (i.e., two Operational Goals), either as modified by the company’s relative TSR achievement measured upon the change in control. Any such resulting “achieved” Performance Awards will be subject to time-based vesting following the change in control through the end of the Performance Period and will be eligible for accelerated vesting in the event of the termination without “cause” or resignation for “good reason” of the Executive in connection with or following the change in control, as provided in the Executive CIC Policy.
The following table provides information concerning the estimated payments and benefits that would be provided in the circumstances described above for each of our eligible NEOs in accordance with the Executive CIC Policy, with no change in control and with change in control in effect on December 31, 2023. Except where otherwise noted, payments and benefits are estimated assuming that the triggering event took place on December 31, 2023, and the price per share of our common stock is the closing price on the grantNasdaq Global Select Market as of December 29, 2023, the last trading day in fiscal year 2023 ($107.04). There can be no assurance that a triggering event would produce the same or similar results as those estimated below if such event occurs on any other date or at any other price, of the award.

Itif any other assumption used to estimate potential payments and benefits is also our policy not to time the grant of equity awards in relationcorrect. Due to the releasenumber of material non-public information,factors that affect the nature and it is the intentamount of the Equity Award Grant Policy to specify the timing of effectiveness of the grant of equity awards under the policy to avoid such timing.any potential payments or benefits, any actual payments and benefits may be different.

The Clawback Policy requires us to recover certain cash or equity-based incentive-based compensation (as defined in the Clawback Policy) paid or granted to our officers, and such additional employees as may be identified from time to time, in the event we are required to prepare an accounting restatement due to our material noncompliance with any financial reporting requirement under the securities laws. The Clawback Policy requires each person covered thereby to reimburse or forfeit to us all incentive-based compensation received by them prior to the restatement that exceeds the amount they would have received had their incentive-based compensation been calculated based on the financial restatement. The recovery period extends up to three years prior to the date that it is, or reasonably should have been, concluded that we are required to prepare a restatement. The Clawback Policy applies to incentive-based compensation that is received (as defined in the Clawback Policy) after the effective date of the applicable Nasdaq rules. Per applicable requirements, the Clawback Policy is enforced without consideration of responsibility or fault or lack thereof.

Processes and Procedures for Compensation Decisions

CEO Pay Ratio
Under the US Dodd-Frank Wall Street Reform and Consumer Protection Act and applicable SEC rules, we are required to disclose the ratio of their Principal Executive Officer’s compensation to that of their median employee. For this required disclosure, Quentin S. Blackford, our President and Chief Executive Officer is considered to be our Principal Executive Officer (“PEO”).
For fiscal year 2023:
the annual total compensation of Quentin Blackford was $16,595,149; and
the estimated median of the annual total compensation of all employees of our company, other than Mr. Blackford, was $94,941.
Based on this information, for 2023 the ratio of the annual total compensation of Mr. Blackford to the median of the annual total compensation of all employees was 174.8 to 1.
The SEC rules for identifying the median employee and calculating the pay ratio permit companies to use various methodologies and assumptions, to apply certain exclusions and to make reasonable estimates that reflect their employee population and compensation practices. As a result, the pay ratio reported by other companies may not be comparable to the pay ratio that we have reported.
To identify the median employee, we used base salary for all of our employees, excluding our PEO, who were employed by us on December 31, 2023. We included full-time, part-time and temporary employees.
After identifying the median employee, we calculated annual total compensation for the median employee using the same methodology we used for determining total compensation for our NEOs as shown in the “2023 Summary Compensation Table” below.

Stockholder Advisory Vote on Named Executive Compensation
At our 2023 Annual Meeting of Stockholders, we conducted a non-binding stockholder advisory vote on the compensation of our NEOs (commonly known as a “Say-on-Pay” vote). Approximately 89.3% of the votes cast approved our executive compensation program for 2022. The Committee is responsible forevaluated the results of the 2023 Say-on-Pay vote and believes the strong stockholder support signals approval of the current pay programs. The Committee also considers many other factors in evaluating the company’s executive compensation programs as discussed in this Compensation Discussion and Analysis, including the assessment of the alignment of the executive compensation programs with the company’s corporate business objectives, evaluations of the programs by the Committee’s independent compensation adviser, and review of the peer group and other market data. While each of these factors bore on the Committee’s decisions regarding the NEOs’ compensation, the Committee determined not to implement significant changes to the executive compensation program for 2023.
We value the opinion of our executive officersstockholders and reportswill continue to ourhold annual Say-on-Pay votes annually. Our Board of Directors and the Committee will continue to consider the results of the Say-on-Pay vote, as well as feedback received throughout the year, when making compensation decisions for our executive officers.

Tax and Accounting Considerations

Deductibility of Executive Compensation

Generally, Section 162(m) of the Internal Revenue Code disallows aof 1986, as amended, limits the amount that we may deduct from our federal income tax deductiontaxes for public corporations of remuneration in excess of one million dollars paid in any fiscal year to certain specified executive officers, which include their chiefexecutives to $1 million per executive officer chief financial officer, any other executive officer whose total compensation is required to be reported to stockholders under the Exchange Act by reason of such individual being among the three highest compensated executive officers for the tax year and any executive officer who was subject to the deduction limit in any tax year beginning after December 31, 2016.

As a result of the Tax Cuts and Jobs Act of 2017, compensation paid to our Named Executive Officers in excess of one million dollars will not be deductible for federal income tax purposes unless it qualifies for transition relief applicable to certain “performance-based compensation” payable pursuant to a binding written agreement in effect on November 2, 2017 and which has not been subsequently modified in any material respect. In other words, performance-based incentive awards outstanding on November 2, 2017 or awarded thereafter pursuant to a binding written agreement that was in effect on that date may be exempt from the deduction limit if the applicable conditions of the former exemption for “performance-based compensation” are satisfied.

In designing our executive compensation program and determining compensation of our executive officers, including our Named Executive Officers, the Compensation Committee considers a variety of factors, including the potential impact of the Section 162(m) deduction limit. However, the Compensation Committee has not and will not necessarily limit executive compensation to that which is or may be deductible under Section 162(m).

per year. To maintain flexibility to compensate our executive officers in a manner designed to promote short-term and long-term corporate goals and objectives, the Compensation Committee has not adopted a policy that all compensation must be deductible. The Compensation Committee believes that our stockholders’ interests are best served if its discretion and flexibility in awarding compensation is not restricted, even though some compensation awards may result in non-deductible compensation expense. Thus, the Compensation Committee may approve compensation for our Named Executive OfficersNEOs that may not be fully deductible because of the deduction limit of Section 162(m) when it believes that such compensation is consistent with the goals of our executive compensation program and is in the best interests of the Companycompany and our stockholders.

Accounting for Stock-BasedNon-Equity Incentive Plan Compensation

($)(4)

All Other Compensation
We follow the Financial Accounting Standard Board’s Accounting Standards Codification Topic 718 (“FASB ASC Topic 718”($) for stock-based compensation awards. FASB ASC Topic 718 requires the measurement of compensation expense for all share-based payment awards made to employees and the non-employee members of our Board of Directors, including options to purchase shares of common stock and other stock awards, based on the grant date “fair value” of these awards. This calculation is performed for accounting purposes and reported in the executive compensation tables required by the federal securities laws, even though the recipient of the awards may never realize any value from their awards.(5)

(1)Amounts in the “Estimated Payouts Under Non-Equity Incentive Plan Awards” columns relate to cash incentive opportunities under our 2023 Annual Bonus Plan based upon the combined achievement of corporate and individual performance goals over fiscal year 2023. The actual amounts paid to our NEOs are set forth in the “2023 Summary Compensation Table” above, and the calculation of the actual amounts paid is discussed more fully in the section titled “Compensation Discussion and Analysis— Annual Cash Bonus Payments.” Because the individual performance multipliers can range from 0-115%, the 2023 Annual Bonus Plan does not have a threshold level of performance.
(2)Represents the hypothetical payments possible under our NEOs’ respective 2023 annual PSUs as described in the section entitled “Compensation Discussion and Analysis-Individual Compensation Elements-Annual Long-Term (LTI) Awards” and 2023 Strategic PSUs as described in the section entitled "Compensation Discussion and Analysis - Individual Compensation Elements - Long-term Strategic PSU Award." The 2023 annual PSUs are earned upon achievement of the Corporate Performance Measures and the 2023 Strategic PSUs are earned over a three-year period upon the achievement of the Operational Goals (further described above). In addition, each of the 2023 annual PSUs and the 2023 Strategic PSUs will be further adjusted based on achievement of TSR versus S&P Healthcare Equipment Select Industry Index. The maximum achievement of the 2023 Strategic PSUs will be 150% of target.
(3)The values of the stock awards reflect the grant date fair value of stock awards granted under our 2016 Equity Incentive Plan during 2023 and are based on the Company’s closing price on the grant date in accordance with FASB ASC Topic 718.

Pension Benefits and Nonqualified Deferred Compensation
Wedonotprovideadefinedbenefitpensionplanforouremployees,andnoneofourNEOsparticipated in a nonqualified deferred compensation plan in 2023.
Tax and Accounting Considerations
Deductibility of Executive Compensation
Section 162(m) of the Internal Revenue Code of 1986, as amended, limits the amount that we may deduct from our federal income taxes for remuneration paid to certain executives to $1 million per executive officer per year. To maintain flexibility to compensate our executive officers in a manner designed to promote short-term and long-term corporate goals and objectives, the Committee has not adopted a policy that all compensation must be deductible. The Committee believes that our stockholders’ interests are best served if its discretion and flexibility in awarding compensation is not restricted, even though some compensation awards may result in non-deductible compensation expense. Thus, the Committee may approve compensation for our NEOs that may not be fully deductible because of the deduction limit of Section 162(m) when it believes that such compensation is consistent with the goals of our executive compensation program and is in the best interests of the company and our stockholders.
Non-Equity Incentive Plan Compensation
We provide each of our Named Executive Officers an opportunity to receive formula-based incentive payments. The payments are based on a target incentive amount for each Named Executive Officer.($)(4)

Potential Payments upon Termination or Change of Control
In August 2020, the Compensation and Talent Management Committee (and, with respect to our CEO, the independent members of our Board of Directors) approved a new Severance and Change in Control Policy (the “Policy”) effective September 2019, which provides a standardized approach for the receipt of severance and change in control payments and benefits by certain employees, including our Named Executive Officers. Under this approach, the rights of our executives with respect to the receipt of payments and benefits upon an involuntary termination of employment, including an involuntary termination of employment in connection with a change in control of the Company, were established on a uniform basis. Generally, the Policy replaced the individual Change of Control and Severance Agreements which we had previously entered into with our Named Executive Officers which had expired at the completion of their two-year term in September 2019.
Under the Policy, if, within the period 3 months prior to and 12 months following a “change of control” (such period, the “Change in Control Period”), we terminate the employment of the applicable employee other than for “cause,” death or “disability,” or the employee resigns for “good reason” (as such terms are defined in the employee’s change of control and severance agreement) and, within 60 days following the employee’s termination, the employee executes an irrevocable separation agreement and release of claims, the employee is entitled to receive from the Company (i) a lump sum severance payment equal to the payment of employee’s base salary, at the highest rate in effect during the term of the agreement, for 24 months for Mr. Blackford, and 15 months for Messrs. Devine, Wilson, Vort and Day, (ii) payment of premiums to maintain group health insurance continuation benefits pursuant to “COBRA” for the employee and the employee’s dependents for up to 24 months for Mr. Blackford, and 15 months for Messrs. Devine, Wilson, Vort and Day, (iii) a sum payment equal to 150% of target bonus in effect for the fiscal year in which termination occurs for Mr. Coyle, and 100% of target bonus for Messrs. Devine, Wilson, Vort and Day, and (iv) accelerated vesting as to 100% of the employee’s outstanding unvested equity awards (if vesting depends on achievement of performance criteria, then assuming performance criteria has been achieved at target levels).
34


In addition, under the Policy, if, outside of a Change in Control Period, we terminate the employment of the applicable employee other than for cause, death or disability, or the employee resigns for good reason and, within 60 days following the employee’s termination, the employee executes an irrevocable separation agreement and release of claims, the employee is entitled to receive (i) continuing payments of severance pay at a rate equal to the aggregate amount of the employee’s base salary, at the highest rate in effect during the term of the agreement, for up to 18 months for Mr. Blackford, and 12 months for Messrs. Devine, Wilson, Vort and Day, and (ii) payment of premiums to maintain group health insurance continuation benefits pursuant to “COBRA” for the employee and the employee’s dependents for 18 months for Mr. Blackford, and 12 months for Messrs. Devine, Wilson, Vort and Day.
Under the Policy, in the event any payment to the applicable Named Executive Officer pursuant to his change of control and severance agreement would be subject to the excise tax imposed by Section 4999 of the Internal Revenue Code, as amended, or the Code (as a result of a payment being classified as a parachute payment under Section 280G of the Code), the officer will receive such payment as would entitle him to receive the greatest after-tax benefit, even if it means that we pay him a lower aggregate payment so as to minimize or eliminate the potential excise tax imposed by Section 4999 of the Code.

The following table describes the potential payments that would have been provided to each of our current Named Executive Officers pursuant to the Policy in the event that they were terminated within the three-month period prior to or the 12-month period following a “change in control” as described above, assuming such termination occurred on December 31, 2021 (except as otherwise noted).Messrs. Coyle and King terminated employment prior to December 31, 2021, and accordingly are not included in this table.

Pay Ratio Disclosure
In August 2015, the SEC issued final rules implementing the provision of the Dodd-Frank Act that requires U.S. publicly traded companies to disclose the ratio of their Principal Executive Officer’s compensation to that of their median employee.

For fiscal year 2021:
the annual total compensation of Quentin Blackford was $9,731,346; and
the estimated median of the annual total compensation of all employees of our company, other than Mr. Blackford, was $64,156.
Based on this information, for 2021 the ratio of the annual total compensation of Mr. Blackford, our PresidentPatrick Murphy; Chief Business Officer and PEO, to the median of the annual compensation of all employees was 151.7 to 1.Chief Legal Officer (8) (11)

Minang Turakhia; Chief Medical Officer, Chief Scientific Officer and calculating the pay ratio permit companies to use various methodologies and assumptions, to apply certain exclusions and to make reasonable estimates that reflect their employee population and compensation practices. As a result, the pay ratio reported by other companies may not be comparable to the pay ratio that we have reported.EVP, Product Innovation (10) (11)
To identify the median employee, we used the base salary for all of our U.S. employees, excluding our PEO, who were employed by us on December 31, 2021. We included full-time, part-time, and temporary employees. Since the time at which we selected our median employee, there has been no significant change in our employee population or employee compensation arrangements that we believe would significantly impact the pay ratio disclosure.
After identifying the median employee, we calculated annual total compensation for the median employee using the same methodology we used for determining total compensation for our Named Executive Officers as shown in the 2021 Summary Compensation Table.

RELATED PERSON TRANSACTIONS
We describe below transactions and series of similar transactions, since the beginning of our last fiscal year, to which we were a party or will be a party, in which:
the amounts involved exceeded or will exceed $120,000; and
any of our directors, nominees for director, executive officers or beneficial holders of more than 5% of our outstanding common stock, or any immediate family member of, or person sharing the household with, any of these individuals or entities (each, a related person), had or will have a direct or indirect material interest.
Certain Transactions with Related Persons
During 2021, the son of Raymond W. Scott, a former member of our Board of Directors and Chairman of our Nominating and Corporate Governance Committee, was employed by the Company as a director of software engineering. Mr. Scott’s son earned total compensation of approximately $506,693. Total compensation includes salary, bonus, and stock awards. The compensation of Mr. Scott’s son is consistent with that of other employees with equivalent qualifications and responsibilities and holding similar positions, and Mr. Scott recused himself from any decision regarding the hiring of, or compensation related to his son.
Executive Officer Employment Letters
We have entered into employment arrangements with certain current executive officers. See “Executive Compensation—Executive Officer Employment Arrangements.”
Indemnification Agreements
We have entered into indemnification agreements with our directors and executive officers. The indemnification agreements and our certificate of incorporation and amended and restated bylaws require us to indemnify our directors and executive officers to the fullest extent permitted by Delaware law.
Policies and Procedures for Related Party Transactions
Our Board of Directors has adopted a written policy that our executive officers, directors, nominees for election as a director, beneficial owners of more than 5% of any class of our common stock and any members of the immediate family of any of the foregoing persons are not permitted to enter into a related person transaction with us without the prior consent of our Audit Committee. Any request for us to enter into a transaction with an executive officer, director, nominee for election as a director, beneficial owner of more than 5% of any class of our common stock or any member of the immediate family of any of the foregoing persons in which the amount involved exceeds $120,000, and such person would have a direct or indirect interest must first be presented to our Audit Committee for review, consideration and approval. In approving or rejecting any such proposal, our Audit Committee is to consider the material facts of the transaction, including, but not limited to, whether the transaction is on terms no less favorable than terms generally available to an unaffiliated third-party under the same or similar circumstances and the extent of the related person’s interest in the transaction. We did not have a formal review and approval policy for related party transactions at the time of any of the transactions described above. However, all of the transactions described above were entered into after presentation, consideration and approval by our Board of Directors and/or our Audit Committee.

__________________________
(1)Amounts in the “Estimated Payouts Under Non-Equity Incentive Plan Awards” columns relate to cash incentive opportunities under our 2023 Annual Bonus Plan based upon the combined achievement of corporate and individual performance goals over fiscal year 2023. The actual amounts paid to our NEOs are set forth in the “2023 Summary Compensation Table” above, and the calculation of the actual amounts paid is discussed more fully in the section titled “Compensation Discussion and Analysis— Annual Cash Bonus Payments.” Because the individual performance multipliers can range from 0-115%, the 2023 Annual Bonus Plan does not have a threshold level of performance.
(2)Represents the hypothetical payments possible under our NEOs’ respective 2023 annual PSUs as described in the section entitled “Compensation Discussion and Analysis-Individual Compensation Elements-Annual Long-Term (LTI) Awards” and 2023 Strategic PSUs as described in the section entitled "Compensation Discussion and Analysis - Individual Compensation Elements - Long-term Strategic PSU Award." The 2023 annual PSUs are earned upon achievement of the Corporate Performance Measures and the 2023 Strategic PSUs are earned over a three-year period upon the achievement of the Operational Goals (further described above). In addition, each of the 2023 annual PSUs and the 2023 Strategic PSUs will be further adjusted based on achievement of TSR versus S&P Healthcare Equipment Select Industry Index. The maximum achievement of the 2023 Strategic PSUs will be 150% of target.
(3)The values of the stock awards reflect the grant date fair value of stock awards granted under our 2016 Equity Incentive Plan during 2023 and are based on the Company’s closing price on the grant date in accordance with FASB ASC Topic 718. For a discussion of our valuation assumptions, see Note 2 and Note 13 to our consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2023, filed with the SEC on February 22, 2024.

Pension Benefits and Nonqualified Deferred Compensation
Wedonotprovideadefinedbenefitpensionplanforouremployees,andnoneofourNEOsparticipated in a nonqualified deferred compensation plan in 2023.
Tax and Accounting Considerations
Deductibility of Executive Compensation
Section 162(m) of the Internal Revenue Code of 1986, as amended, limits the amount that we may deduct from our federal income taxes for remuneration paid to certain executives to $1 million per executive officer per year. To maintain flexibility to compensate our executive officers in a manner designed to promote short-term and long-term corporate goals and objectives, the Committee has not adopted a policy that all compensation must be deductible. The Committee believes that our stockholders’ interests are best served if its discretion and flexibility in awarding compensation is not restricted, even though some compensation awards may result in non-deductible compensation expense. Thus, the Committee may approve compensation for our NEOs that may not be fully deductible because of the deduction limit of Section 162(m) when it believes that such compensation is consistent with the goals of our executive compensation program and is in the best interests of the company and our stockholders.
Accounting for Stock-Based Compensation
We follow the Financial Accounting Standard Board’s Accounting Standards Codification Topic 718 (“FASB ASC Topic 718”) for stock-based compensation awards. FASB ASC Topic 718 requires the measurement of compensation expense for all share-based payment awards made to employees and the non-employee members of our Board of Directors, including options to purchase shares of common stock and other stock awards, based on the grant date “fair value” of these awards. This calculation is performed for accounting purposes and reported in the executive compensation tables required by the federal securities laws, even though the recipient of the awards may never realize any value from their awards.

Limitations on Liability and Indemnification Matters
Our Amended and Restated Certificate of Incorporation contains provisions that limit the liability of our directors for monetary damages to the fullest extent permitted by the DGCL. Consequently, our directors will not be personally liable to us or our stockholders for monetary damages for any breach of fiduciary duties as directors, except liability for:
any breach of the director’s duty of loyalty to us or our stockholders;
any act or omission not in good faith or that involves intentional misconduct or a knowing violation of law;
unlawful payments of dividends or unlawful stock repurchases or redemptions as provided in Section 174 of the DGCL; or
any transaction from which the director derived an improper personal benefit.
Further, if the Certificate of Amendment described in Proposal 5 is approved by our stockholders, we will provide for the exculpation of officers, to the fullest extent permitted by law, including for personal liability for breach of fiduciary duty. This exculpation would not protect officers from liability for breach of the duty of loyalty, acts, or omissions not in good faith or that involve intentional misconduct or a knowing violation of law or any transaction in which the officer derived an improper personal benefit. Nor would this exculpation shield such officers from liability for claims brought by or in the right of our company, such as derivative claims. Our current Amended and Restated Certificate of Incorporation and our amended and restated bylaws require us to indemnify our directors and officers to the maximum extent not prohibited by the DGCL and allow us to indemnify other employees and agents as set forth in the DGCL. Subject to certain limitations, our amended and restated bylaws also require us to advance expenses incurred by our directors and officers for the defense of any action for which indemnification is required or permitted, subject to very limited exceptions.
We have entered, and intend to continue to enter, into separate indemnification agreements with our directors, officers, and certain of our other employees, in addition to the indemnification provided for in our Amended and Restated Certificate of Incorporation and amended and restated bylaws. These agreements, among other things, require us to indemnify our directors, officers and key employees for certain expenses, including attorneys’ fees, judgments, fines, and settlement amounts actually and reasonably incurred by such director, officer or key employee in any action or proceeding arising out of their service to us or any of our subsidiaries or any other company or enterprise to which the person provides services at our request. Subject to certain limitations, our indemnification agreements also require us to advance expenses incurred by our directors, officers, and key employees for the defense of any action for which indemnification is required or permitted.
We believe that these provisions of our Amended and Restated Certificate of Incorporation and indemnification agreements are necessary to attract and retain qualified persons such as directors, officers, and key employees. We also maintain directors’ and officers’ liability insurance.
The limitation of liability and indemnification provisions in our Amended and Restated Certificate of Incorporation and restated bylaws or in these indemnification agreements may discourage stockholders from bringing a lawsuit against our directors and officers for breaches of their fiduciary duties. They may also reduce the likelihood of derivative litigation against our directors and officers, even though an action, if successful, might benefit us and other stockholders. Further, a stockholder’s investment may be adversely affected to the extent that we pay the costs of settlement and damage awards against directors and officers as required by these indemnification provisions.
Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, executive officers or persons controlling us, we have been informed that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

(7)    The Peer Group TSR set forth in column (g)(1) in this table utilizes the NASDAQ Biotechnology Index, and the Peer Group TSR set forth in column (g)(2) in this table utilizes the S&P Healthcare Equipment Select Industry, which we also utilize in the stock performance graph required by Item 201(e) of Regulation S-K included in our Annual Report for the year ended December 31, 2023. For the year ended December 31, 2023, the Company has elected to present the S&P Healthcare Equipment Select Industry for its peer group comparison. The Company believes that the holdings of this index more accurately reflect its peer companies. Since the NASDAQ Biotechnology Index was presented in the prior year, it has also been presented in the current year for comparison purposes. The comparison assumes $100 was invested for the period starting December 31, 2019, through the end of the listed year in the Company, the NASDAQ Biotechnology Index and the S&P Healthcare Equipment Select Industry, respectively. Historical stock performance is not necessarily indicative of future stock performance.
(8)    We determined revenue to be the most important financial performance measure used to link Company performance to Compensation Actually Paid to our PEO and Non-PEO NEOs in 2023 and 2022. This performance measure may not have been the most important financial performance measure for years 2021 and 2020 we may determine a different financial performance measure to be the most important financial performance measure in future years.

Policies and Procedures for Related Person Transactions
Our Board of Directors has adopted a written related person transaction policy that sets forth the following policies and procedures for the review and approval or ratification of related person transactions. A “related person transaction” is a transaction, arrangement or relationship in which the post-combination company or any of its subsidiaries was, is or will be a participant and in which any related person had, has or will have a direct or indirect material interest. A “related person” means executive officer, director, nominee for election as a director, beneficial owner of more than 5% of any class of our common stock or any member of the immediate family of any of the foregoing persons.
We have policies and procedures designed to minimize potential conflicts of interest arising from any dealings it may have with its affiliates and to provide appropriate procedures for the disclosure of any real or potential conflicts of interest that may exist from time to time. Specifically, pursuant to its Audit Committee charter, the Audit Committee has the responsibility to review related party transactions.

“Householding” - Stockholders Sharing the Same Last Name and Address
The SEC has adopted rules that permit companies and intermediaries (such as brokers) to implement a delivery procedure called “householding.” Under this procedure, multiple stockholders who reside at the same address may receive a single copy of our Annual Report and proxy materials, including the Notice of Internet Availability, unless the affected stockholder has provided contrary instructions. This procedure reduces printing costs and postage fees and helps protect the environment as well.
This year, a number of brokers with account holders who are our stockholders will be “householding” our Annual Report and proxy materials, including the Notice of Internet Availability. A single Notice of Internet Availability and, if applicable, a single set of Annual Report and other proxy materials will be delivered to multiple stockholders sharing an address unless contrary instructions have been received from the affected stockholders. Once you have received notice from your broker that it will be “householding” communications to your address, “householding” will continue until you are notified otherwise or until you revoke your consent. Stockholders may revoke their consent at any time by calling Broadridge at (866) 540-7095 or writing to Broadridge, Householding Department, 51 Mercedes Way, Edgewood, New York, 11717.
Upon written or oral request, we will promptly deliver a separate copy of the Notice of Internet Availability and, if applicable, our Annual Report and other proxy materials to any stockholder at a shared address to which a single copy of any of those documents was delivered. To receive a separate copy of the Notice of Internet Availability and, if applicable, Annual Report and other proxy materials, you may write our Corporate Secretary at 699 8th Street, Suite 600, San Francisco, California 94103, Attn: Corporate Secretary, telephone number (415) 632-5700.
Any stockholders who share the same address and receive multiple copies of our Notice of Internet Availability or Annual Report and other proxy materials who wish to receive only one copy in the future can contact their bank, broker or other holder of record to request information about householding or our Corporate Secretary at the address or telephone number listed above.

NON-GAAP FINANCIAL MEASURES
We refer to certain financial measures that are not recognized under U.S. generally accepted accounting principles (GAAP) in this Proxy Statement, including adjusted EBITDA, adjusted net loss, adjusted net loss per share and adjusted operating expenses. We use these non-GAAP financial measures for financial and operational decision-making and as a means to evaluate period-to- period comparisons.
Adjusted EBITDA excludes non-cash operating charges for stock-based compensation, depreciation and amortization as well as non-operating items such as interest income, interest expense, impairment and restructuring charges, and business transformation costs. See Appendix B hereto for reconciliations of non-GAAP financial measures included herein.
We exclude the following items from non-GAAP financial measures for adjusted net loss, adjusted net loss per share and adjusted operating expenses:
