Letter to Masimo Corporation Stockholders
	Joe Kiani Chairman and Chief Executive Officer April 15, 2021
Dear Fellow Stockholders: Last year was full of challenges for our customers and for millions of patients around the world who struggled to overcome the burden and effects of the COVID-19 ('COVID') pandemic. Throughout 2020, as our customers on the front lines responded to this crisis and tried to save as many lives as possible under life-threatening conditions, we responded to their demands to rapidly secure and install new monitoring technologies, enabling them to accommodate more critically ill patients than ever before, even at home. Within this tough environment, I am proud to say that our team contributed to the critical solutions that were, and are still, required to manage this pandemic. In the midst of the pandemic, last year was also a milestone year for Masimo as our revenues exceeded $1 billion for the first time since our founding over 30 years ago. Today, we are even more committed to helping our customers overcome the persistent challenges related to this pandemic with an expanding portfolio of products to improve patient outcomes. We realized many significant achievements in 2020 such as the introduction of our Masimo SafetyNet™ system for enabling hospital-to-home monitoring while also capturing a wider customer base for our Patient SafetyNet solution that enables hospitals to streamline workflows and improve patient care, especially where hospital staff are overwhelmed due to many COVID patient admissions. Within Masimo, our dedicated team was nimble in its response to our customers in the face of significant demand for our existing products, while at the same time expanding our portfolio. This expansion included several important products beyond SafetyNet™ for COVID, some organic, such as the Radius-Tº™ continuous wearable thermometer, Centroid™continuous wearable bed sore and fall detection monitor, and Masimo SafetyNet-OPEN™ to help institutions open and stay open safely, and other important products acquired through acquisitions, such as the SoftFlow™ High Flow Nasal Cannula respiratory support system from TNI and the LiDCO cardiac output and hemodynamic monitor. We are excited to bring these clinically relevant technologies to our growing customer base around the world. On the financial front, we were happy to report full-year 2020 results that exceeded expectations and set the stage for another promising year ahead. For the full-year, our product revenues increased 22% to reach one billion, one hundred and forty-four million ($1,144 million). In addition, we delivered GAAP EPS growth of 20% to reach $4.14 per share and non-GAAP EPS(1)growth of 12% to reach $3.60 per share. We were able to achieve this level of performance despite the unprecedented challenges related to the pandemic facing our organization, which required many modifications to our operations and the sheer determination and commitment of our team. We instituted multiple safety measures throughout, including at our manufacturing facilities, such as regular health and temperature checks as well as safe transportation protocols for our team members. This internal solution was the basis for Masimo SafetyNet-OPEN™, recently launched worldwide for others to use. Changes to our operations also included the production of greater inventory levels of the products our customers relied upon to provide care to their patients as we believed it prudent to prepare for a scenario where COVID would prevent our plants from operating. Fortunately, that never happened and hopefully will not happen, but we will continue to be prepared. Our customer interactions in the field were also carefully maintained in the face of heavy restrictions on hospital visitors, as our sales and installation teams rose to the occasion to ensure timely deliveries, training and product activations as rapidly as possible. Lastly, while many of our team members worked from home, most of our exceptional team of engineers continued their activities at Masimo facilities to maintain the unparalleled pace of innovation that has always been our hallmark. Thank you for your continued support of Masimo and I hope you will be able to join us for the Annual Meeting. Joe Kiani Chairman and Chief Executive Officer

Executive Compensation Highlights

Masimo's executive compensation programs are designed to align the interests of Masimo's executive officers with those of its stockholders, attract and retain highly-talented individuals and support our long-term growth and profitability goals. Our compensation programs provide a mix of fixed, variable and long-term incentive ('LTI') compensation elements that are closely aligned with company performance and are sensitive to our stock performance, including the following:

Type	Component	Objective
Fixed compensation	Base salary	l	Fixed portion of annual cash compensation
	l	Attract and retain talent
l	Motivate strong business performance without encouraging excessive risk-taking
Performance-based Compensation	Annual incentive	l	Variable, earned amounts paid annually
	l	Drive the achievement of key business results on an annual basis
l	Recognize individuals based on their contributions
l	Performance-based and not guaranteed
Long-term incentives	l	Variable, equity-based:
	l 25% in the form of stock options that vest annually over a five year period; and
l 75% in the form of performance share units ('PSUs') that vest after three years based on our actual performance as measured against multiple pre-established performance objectives at the end of the multi-year performance period
l	Reinforce the need for long-term sustained performance and business growth, and value creation
l	Focus executives on annual objectives that support the long-term business strategy and creation of stockholder value
l	Align the long-term interests of executives and stockholders
l	Balance cash payments with equity ownership
l	Encourage retention

Total Target Compensation

Masimo's 'at-risk' compensation (which includes the annual cash bonus and LTI compensation) comprised 92.2% of our Chief Executive Officer's ('CEO') compensation and an average of 80.2% of the compensation of our other Named Executive Officers' ('NEOs') FY2020 total target compensation, as seen below:

Total long-term incentive compensation =	81.0%	Total long-term incentive compensation =	66.0%
Total 'at-risk' compensation =	92.2%	Total 'at-risk' compensation =	80.2%

Our compensation philosophy and structure has continued to evolve, based on changing market conditions, input from our Compensation Committee's independent compensation consultant and direct feedback from our stockholders. The Compensation Committee believes that the current LTI equity award structure focuses our NEOs on driving increased stockholder value over a multi-year period and enables us to achieve our retention objectives, while maintaining a conservative approach to overall share usage.

Class I, Class II and Class III directors currently have a remaining term of office until the 2021, 2022 and 2023 Annual Meeting of Stockholders, respectively. Vacancies on the Board may be filled only by persons elected by a majority of the remaining directors in office (even though the remaining directors may constitute less than a quorum). A director elected by our Board to fill a vacancy in a Class, including a vacancy created by an increase in the number of directors, will serve for the earlier of the remainder of the full term of that Class, until the director's successor is elected and qualified or until the director's death, resignation or removal.

Complete copies of the charters of the committees of our Board and our Code of Business Conduct and Ethics described below may be viewed on our website at https://investor.masimo.com/governance/governance-documents/default.aspx under 'Governance Documents.' Alternatively, you can request a copy of any of these documents free of charge by writing to our Corporate Secretary, c/o Masimo Corporation, 52 Discovery, Irvine, California 92618.

CORPORATE GOVERNANCE PRACTICES

Our Board has adopted corporate governance guidelines to ensure that our Board will have the necessary authority and practices in place to exercise its duties and responsibilities, to review and evaluate our business operations as needed, to make decisions that are independent of our management and to serve the best interests of Masimo and our stockholders. These corporate governance guidelines provide a framework for the conduct of the Board's business and provide that:

•except in unusual circumstances, the positions of Chairman of our Board and CEO will be held by the same person;

•ordinarily, directors should not serve on more than five boards of publicly-traded companies, including our Board, and all of our directors currently satisfy this requirement;

•outside directors must own a minimum number of shares of our common stock (see 'Non-Employee Director Compensation-Non-Employee Director Stock Ownership Policy' on page 39 of this Proxy Statement for additional information); and

•a non-employee director will not be nominated for re-election at the next annual meeting of stockholders for which his or her class of directors is up for election following his or her 15th anniversary of service on our Board, unless our Board waives this term limit with respect to such non-employee director as a result of its determination that such nomination is in the best interests of Masimo and its stockholders.

CHARACTERISTICS OF OUR BOARD(1)

3 New directors joined the Board since 2016	5 Year Board Refreshment rate: 50%	20% Women
Average tenure of our Board: 3.6 Years	Average Age of our Board: 62	100% Independent (non-employees)

____________________________

CONSIDERATION OF DIRECTOR NOMINEES

Director Qualifications

The Board does not prescribe any minimum qualifications for director candidates.The Nominating, Compliance and Corporate Governance Committee may consider a potential director candidate's experience, areas of expertise and other factors relative to the overall composition of our Board and its committees, including the following characteristics:

•the highest ethical standards and integrity and a strong personal reputation;

•a background that demonstrates experience and achievement in business, finance, technology, healthcare or other activities relevant to our business and activities;

•a willingness to act on and be accountable for Board and, as applicable, committee decisions;

•an ability to provide reasoned, informed and thoughtful counsel to management on a range of issues affecting us and our stockholders;

•an ability to work effectively and collegially with other individuals;

•loyalty and commitment to driving our success and increasing long-term value for our stockholders;

•sufficient time to devote to our Board and, as applicable, committee membership and matters; and

•meeting the independence requirements imposed by the SEC and Nasdaq.

Diversity of background, including diversity of gender, race, ethnic or national origin, and experience (including in business, finance, government, technology, healthcare or other activities relevant to our business) is also a relevant factor, as a diverse Board is more likely to reflect varying perspectives and a breadth of experience that will positively contribute to robust discussion at Board meetings.

The Nominating, Compliance and Corporate Governance Committee retains the right to modify these criteria from time to time.

Stockholder Nominations and Proxy Access

The Nominating, Compliance and Corporate Governance Committee will consider director candidates recommended by our stockholders. The Nominating, Compliance and Corporate Governance Committee does not intend to alter the manner in which it evaluates candidates based on whether a candidate was recommended by a stockholder or not. Stockholders may nominate directors for election if such stockholders satisfy the advance notice provisions set forth in our Bylaws. To be timely for our 2022 Annual Meeting of Stockholders, stockholders who wish to recommend individuals for consideration by the Nominating, Compliance and Corporate Governance Committee to become nominees for election to the Board at the 2022 Annual Meeting of Stockholders, must do so by delivering a written recommendation to the Nominating, Compliance and Corporate Governance Committee, c/o Masimo Corporation, 52 Discovery, Irvine, California 92618, Attention: Corporate Secretary, no later than the close of business on March 1, 2022, and no earlier than January 30, 2022, unless the meeting date is more than 30 days before or after May 27, 2022, in which case the written recommendation must be received by our Corporate Secretary no later than the close of business on the later of (i) the 90th day before the 2022 Annual Meeting of Stockholders, or (ii) the 10th day following the day on which we first publicly announce the date of the 2022 Annual Meeting of Stockholders.

Each written recommendation must contain the following minimum information:

•the name and address of the stockholder and any beneficial owner on whose behalf the nomination is being made;

•the class, series and number of shares of Masimo, and any convertible securities of Masimo, that are beneficially owned by the stockholder and any beneficial owner on whose behalf the nomination is being made;

•any proxy, contract, arrangement, understanding or relationship pursuant to which the stockholder and any beneficial owner on whose behalf the nomination is being made has the right to vote any of Masimo's voting securities;

•any 'short' interest in Masimo's securities held by the stockholder and any beneficial owner on whose behalf the nomination is being made;

•the proposed director candidate's full legal name, age, business address and residential address;

•complete biographical information for the proposed director candidate, including the proposed director candidate's principal occupation or employment and business experience for at least the previous five years;

•a description of the proposed candidate's qualifications as a director;

•the class and number of shares of Masimo that are beneficially owned by the proposed director candidate as of the date of the written recommendation; and

•any other information relating to the proposed director candidate that is required to be disclosed in solicitations for proxies for election of directors pursuant to Regulation 14A promulgated under the Securities Exchange Act of 1934, as amended (the 'Exchange Act').

Director candidate recommendations from stockholders must include the written consent of each proposed nominee to serve as director if so elected. If a proposed director candidate is recommended by a stockholder in accordance with the procedural requirements discussed above, the Corporate Secretary will provide the foregoing information to the Nominating, Compliance and Corporate Governance Committee.

In 2019, we amended our Bylaws to permit eligible stockholders to nominate candidates for election to the Board in accordance with procedures providing for proxy access (the 'Proxy Access Bylaw'). The Proxy Access Bylaw may be used by an eligible stockholder, or a group of up to 20 eligible stockholders, who has continuously owned at least 3% of the outstanding shares of our common stock for at least the three years before, and including the day of the submission of the proxy access notice, who continues to hold the qualifying minimum number of shares through the date of the applicable annual meeting of stockholders, so long as the eligible stockholder(s) and the director nominee(s) satisfy the requirements specified in the Proxy Access Bylaw. The Proxy Access Bylaw further provides that an eligible stockholder, or a group of eligible stockholders, may nominate up to the greater of (i) 25% of the total number of directors who are members of the Board as of the last day on which a proxy access notice may be submitted, or (ii) two directors, subject to reduction in the event a director has been elected to the Board through proxy access at one of the two immediately preceding annual meetings of our stockholders.

Stockholders who wish to recommend director nominees for inclusion in our proxy materials at the 2022 Annual Meeting of Stockholders in compliance with the Proxy Access Bylaw must do so by delivering a proxy access notice to be received by our Corporate Secretary no earlier than November 16, 2021, and no later than December 16, 2021. In the event that the date of the 2022 Annual Meeting of Stockholders is more than 30 days before or after May 27, 2022, such proxy access notice must be received by the later of (i) 180 days prior to the 2022 Annual Meeting of Stockholders, or (ii) the 10th day following the date that the 2022 Annual Meeting of Stockholders is first publicly announced or disclosed.

Evaluating Nominees for Director

Our Nominating, Compliance and Corporate Governance Committee will consider director candidates that are recommended by members of the committee, other members of our Board, members of management, advisors and our stockholders who submit recommendations in accordance with the requirements set forth above.

The Nominating, Compliance and Corporate Governance Committee may also retain a third-party search firm to identify candidates on terms and conditions acceptable to the Nominating, Compliance and Corporate Governance Committee, but has not done so to date. The Nominating, Compliance and Corporate Governance Committee will evaluate all candidates for director using the same approach regardless of who recommended them.

The Nominating, Compliance and Corporate Governance Committee will review candidates for director nominees in the context of the current composition of our Board and committees, the operating requirements of the Company and the long-term interests of our stockholders. In conducting this assessment, the Nominating, Compliance and Corporate Governance Committee may consider the director nominee's qualifications, diversity, age, skills and such other factors as it deems appropriate given the current needs of the Board, the committees and Masimo, to maintain a balance of knowledge, experience, diversity and capability. In the case of incumbent directors whose terms of office are set to expire, the Nominating, Compliance and Corporate Governance Committee may review such directors' overall service to the Board, the committees and Masimo during their term, including the number of meetings attended, level of participation, quality of performance and any other relationships and transactions that might impair such directors' independence. In the case of new director candidates, the Nominating, Compliance and Corporate Governance Committee will also determine whether the nominee must be independent for Nasdaq purposes, which determination will be based upon applicable Nasdaq listing standards and applicable SEC rules and regulations. Although we do not have a formal diversity policy, when considering diversity in evaluating director nominees, the Nominating, Compliance and Corporate Governance Committee will focus on whether the nominees can contribute varied perspectives, skills, experiences and expertise to the Board. Diversity of background, including diversity of gender, race, ethnic or national origin, and experience (including in business, finance, government, technology, healthcare or other activities relevant to our business) is also a relevant factor in considering nominees to the Board, as a diverse Board is more likely to reflect varying perspectives and a breadth of experience that will positively contribute to robust discussion at Board meetings.

The Nominating, Compliance and Corporate Governance Committee will evaluate each of the director candidates and recommend whether the Board should nominate the proposed director candidate for election by our stockholders.

BOARD LEADERSHIP STRUCTURE

Our Board believes that our CEO is best situated to serve as Chairman because he is the director who is most familiar with our business and industry, possesses detailed and in-depth knowledge of the issues, opportunities and challenges facing us and is therefore best positioned to ensure that the Board's time and attention are focused on the most critical matters. Our independent directors bring experience, oversight and expertise from outside the Company and industry, while the CEO brings Company-specific experience and expertise. The Board believes that the combined role of Chairman and CEO facilitates information flow between management and the Board, which is essential to effective governance. We have no lead independent director.

BOARD'S ROLE IN RISK OVERSIGHT

Our Board has an active role, as a whole and also at the committee level, in overseeing the management of our risks. Each committee is responsible for evaluating certain risks and overseeing the management of such risks and reporting to the entire Board as necessary.

INVESTOR FEEDBACK AND ENGAGEMENT

In an effort to foster direct, open and transparent communication with our investors and stockholders, Masimo's leadership and investor relations team met with analysts and stockholders, as well as potential stockholders, at ten conferences, five roadshows and three bus tours during fiscal 2020. In addition, we hosted quarterly earnings calls, and also engaged with investors via frequent phone calls and emails.

We value the feedback from our investors and stockholders. During fiscal 2020, the Chairman of our Compensation Committee and members of management were involved in more than 15 in-person or telephonic meetings with stockholders representing more than 45% of our outstanding shares. These discussions covered topics such as long-term strategy, financial and operating performance, risk management, executive compensation and governance practices. We found these meetings to be informative, and they help us shape our compensation programs and other strategic priorities.

CORPORATE RESPONSIBILITY & SUSTAINABILITY

Under the guidance and supervision of the Board, we pursue high standards of corporate responsibility and sustainability, including how we support, protect and empower our employees, how we work with our customers, how we govern the Company and how we connect with our communities.

	Environment
l	Masimo is committed to operating in an environmentally responsible manner and supports the internationally recognized environmental principles set forth in the United Nations Global Compact.	l	We actively seek to decrease our energy consumption through the use of energy efficient fixtures and machinery, occupancy sensors, motion sensors, and automated lighting controls.
Minimizing our environmental impact	We strive to identify new opportunities to improve the sustainability of our business and encourage our employees to join in our efforts.	l	We have installed solar photovoltaic panels on key facilities to supply our energy needs for lighting, HVAC, manufacturing needs and electric vehicle charging.
As a global manufacturer of patient monitoring technology, our mission is to improve patient outcomes and reduce the cost of care. We also understand that the materials we use and the products we manufacture, which include single-patient-use sensors, have an impact on the environment.	l	The lightweight design of our latest generation of RD patient sensors reduces material waste versus our traditional cable-based sensors. Based on our sales of the RD sensors from 2016 to 2020, the new sensors have resulted in approximately 1,100 metric tons of material eliminated.
Masimo is always considering ways to reduce the company's overall environmental footprint. We have implemented and will continue to implement measures to promote greater environmental responsibility, conserve resources, and reduce waste in an effort to help combat climate change.	l	To reduce landfill waste, we recycle returned Masimo products to harness re-useable natural elements and materials to minimize raw material usage.
	Supply Chain
l	Suppliers are critical partners in the Masimo value supply chain. We are committed to efforts to prevent forced labor, modern slavery and human trafficking and child labor in our supply chain.	l	We are committed to further improving our supply chain due diligence processes, driving accountability within the supply chain by leveraging the industry standard Responsible Mineral Initiative - Conflict Mineral Reporting Template and continuing our outreach efforts in order to further develop transparency in our supply chain and mitigate the risk that Masimo's use of conflict minerals benefits or finances armed groups.
Responsibility in supply chain	l	Ethical sourcing is an important facet of our ethical conduct strategy. Masimo prohibits any form of forced labor, including slavery and human trafficking in its supply chain. Masimo evaluates suppliers through questionnaires, supplier audits, and risk-based assessments.

	Workforce/Workplace
l	We understand the need for great ideas, innovation and leadership to stay current and relevant.	l	We are committed to maintaining a safe workplace environment free from discrimination and harassment.
Building an innovative, collaborative and diverse workforce	l	We seek to retain our employees through fair and competitive compensation, benefits and challenging work experiences with increasing levels of responsibility.	l	We do not tolerate employment discrimination based on race, religion, gender, age, marital status, national origin, sexual orientation, citizenship status, disability or other protected characteristics.

CYBERSECURITY RISK PRACTICES

Cybersecurity is a critical component of our risk management. We rely on information technology and any failure, inadequacy, interruption or security lapse of such technology, including any cybersecurity incidents, could harm our ability to operate our business effectively.

Our cybersecurity program is focused on the following:

•Cybersecurity Awareness: We identify and assess cyber risks through the dissemination of information from industry groups and third-party experts.

•Training: We provide annual cybersecurity training for company personnel with network access and conduct periodic phishing exercises.

•Technical Safeguards: We deploy measures to protect our network perimeter and internal information technology platforms, such as internal and external firewalls, network intrusion detection and prevention, penetration testing, vulnerability assessments, threat intelligence, anti-malware and access controls.

•Vendor Management:For our vendors that receive personal information, we maintain data protection agreements that contain contractual provisions requiring safeguards for the protection of the personal information.

•Incident Response Plans: We maintain and update incident response plans that address the life cycle of a cyber incident (i.e., detection, response and recovery), as well as data breach response, and test those plans annually with table-top exercises.

•Mobile Security: We deploy controls to prevent loss of data through mobile devices.

•Security Standards: We hold accreditations for information and security standards for HIPAA, HITRUST, NIST CSF, and PCI DSS.

•Insurance: Wemaintain a cybersecurity insurance program with established and respected insurance companies.

HUMAN CAPITAL MANAGEMENT

At the core of our long-term strategy for human capital management is attracting, developing and retaining the best talent globally with the right skills to drive our future success. We seek to attract and retain highly talented, highly motivated, experienced and well-educated individuals to support our long-term growth and profitability goals.

Our success and future growth is largely dependent on our continued ability to retract, retain and develop a diverse workforce at all levels of the organization. To succeed, we have developed key recruitment and retention strategies that we focus on as part of our overall management of our business. These include:

•Compensation. Our compensation programs are designed to align the compensation of our employees with their performance and to provide the proper incentives to attract, retain and motivate employees to achieve

superior results. The structure of our compensation programs balances incentive earnings for both short-term and long-term performance.

▪We utilize a nationally-recognized compensation consultants to evaluate our executive compensation program.

▪Our executive compensation program is designed so that a significant portion of compensation is 'at-risk' based on performance, to align the interests of our executive officers and stockholders.

▪We provide employee wages that are competitive and consistent with employee positions, experience, skills, knowledge and geography.

▪A large part of our employee population has received equity as part of their overall compensation, which helps align our employee's interests with those of our stockholders.

▪Annual increases and cash incentives are based on merit, and not guaranteed.

▪We offer a wide variety of benefits, including health insurance, paid time off, and a retirement plan, as well as voluntary benefits such as financial and personal wellness benefits.

•Health and Safety. We are committed to the safety and well-being of our employees. In response to the COVID-19 pandemic, we implemented changes to our business in an effort to protect our employees and customers. A majority of our employees worked remotely during most of 2020, and we instituted safety protocols and procedures for our essential employees who continued to work on-site, including:

▪Daily temperature checks upon entering all facilities;

▪Implementation of Masimo SafetyNet™ to pre-clear employees entering our main campus facilities;

▪Installation of plexiglass partitions between work stations for our manufacturing/assembly facilities; and

▪Increased distancing and implementation of extensive cleaning and sanitation procedures for our manufacturing and assembly facilities as well as our general administration and sales facilities.

•Succession Planning.We are committed to identifying and developing the talents of our next generation of leaders. Our executive management team periodically conducts an organization and leadership review of all business units and leaders, focusing on our high-performing and high-potential talent, diversity, and succession planning for critical roles.

•Employee Feedback and Retention. In November 2020, we were certified as a Great Place to Work®.To assess and improve employee retention and engagement, we periodically survey employees and take actions to address areas of employee concerns. The average tenure of our employee is approximately 5.5 years and more than 20% of our employees have been employed by us for more than ten years.

•Diversity. Our workforce grew from approximately 1,600 full-time employees and approximately 3,700 dedicated contract personnel worldwide as of December 28, 2019 to approximately 2,000 full-time employees and approximately 4,200 dedicated contract personnel worldwide as of January 2, 2021. Of our full-time employees, approximately 65% were male and approximately 35% were female, and women represented approximately 27% of our management/leadership roles. Minorities represented approximately 49% of our U.S. workforce, and approximately 39% of the employees in our management/leadership roles.

CHARITABLE OUTREACH

We undertake philanthropic activities both directly and indirectly through the non-profit organizations we support throughout the globe. We believe in being an active corporate citizen and, among other things, support programs, initiatives and research designed to improve patient safety and outcomes, promote efficient and cost-effective healthcare delivery, and provide advanced healthcare to people worldwide who may not otherwise have access to lifesaving technologies.

ADOPTION OF PROXY ACCESS

The Proxy Access Bylaw may be used by an eligible stockholder, or a group of up to 20 eligible stockholders, who has continuously owned at least 3% of the outstanding shares of our common stock for at least the three years before, and including the day of the submission of the proxy access notice, who continues to hold the qualifying minimum number of shares through the date of the applicable annual meeting of stockholders, provided that the eligible stockholder(s) and the director nominee(s) satisfy the requirements specified in the Proxy Access Bylaw.

MEETINGS AND EXECUTIVE SESSIONS

Our Board meets on a regular basis throughout the year to review significant developments affecting the Company and to act upon matters requiring its approval. Our Board also holds special meetings, as required from time to time, when important matters arise requiring Board action between scheduled meetings. During fiscal 2020, our Board met five times. None of our directors attended fewer than 75% of the total number of meetings held by the Board and the committees (on which and for the period during which the director served) during fiscal 2020.

As required under applicable Nasdaq listing standards, our independent directors periodically meet in executive sessions at which only they are present.

POLICY REGARDING BOARD MEMBER ATTENDANCE AT ANNUAL MEETINGS

It is the policy of our Board to invite directors and nominees for director to attend annual meetings of our stockholders. We held one Annual Meeting of Stockholders in fiscal 2020, which was attended by Mr. Kiani.

INDEPENDENCE OF THE BOARD OF DIRECTORS

Our Board has the responsibility for establishing corporate policies and for the overall performance of the Company, although it is not involved in day-to-day operations. As required under the Nasdaq rules, a majority of the members of our Board must qualify as 'independent' as affirmatively determined by our Board. Our Board consults with our counsel to ensure that the Board's determinations are consistent with all relevant securities and other laws and regulations regarding the definition of 'independent' including those set forth in applicable Nasdaq rules. Consistent with these considerations, after review of all relevant transactions or relationships between each director, and the director's family members and Masimo, our senior management, and our independent registered public accounting firm, our Board has determined that all of our directors other than Mr. Kiani are independent, as that term is defined in Nasdaq Listing Rule 5605(a)(2).

CODE OF BUSINESS CONDUCT AND ETHICS

We have adopted a Code of Business Conduct and Ethics that applies to all of our employees, executive officers and directors. The Code of Business Conduct and Ethics is available to stockholders on our website at https://investor.masimo.com/governance/governance-documents/default.aspx under 'Governance Documents.' If we make any substantive amendments to our Code of Business Conduct and Ethics or grant any waiver from a provision of the Code of Business Conduct and Ethics to any executive officer or director, we will promptly disclose the nature of the amendment or waiver on our website at https://investor.masimo.com/governance/governance-documents/default.aspx under 'Governance Documents' and/or in our public filings with the SEC.

STOCKHOLDER COMMUNICATIONS WITH THE BOARD OF DIRECTORS

Our Board has adopted a formal process by which stockholders may communicate with the Board or any of its directors. Stockholders of Masimo wishing to communicate with our Board or an individual director may send a written communication to the Board or such director, c/o Masimo Corporation, 52 Discovery, Irvine, California 92618, Attention: Compliance Officer. Each communication must set forth:

•the name and address of all the Masimo stockholders on whose behalf the communication is sent; and

•the number of Masimo shares that are beneficially owned by the stockholders as of the date of the communication.

Each communication will be reviewed by Masimo's Compliance Officer to determine whether it is appropriate for presentation to the Board or the individual director. Examples of inappropriate communications include junk mail, spam, mass mailings, product complaints, product inquiries, new product suggestions, resumes, job inquiries, surveys, business solicitations and advertisements, as well as unduly hostile, threatening, illegal, unsuitable, frivolous, patently offensive or otherwise inappropriate material. These screening procedures have been approved by a majority of the independent members of our Board. Communications determined by our Compliance Officer to be appropriate for presentation to the Board or such director will be submitted to the Board or the individual director on a periodic basis.

In accordance with our Open Door Policy for Reporting Accounting, Audit, and Other Compliance Concerns (the 'Open Door Policy'), all communications directed to the Board, a committee of the Board or an individual director relating to accounting topics, internal accounting controls, or auditing matters involving the Company are forwarded to our Compliance Officer regardless of the method of communication, and then promptly and directly forwarded by the Compliance Officer to the Audit Committee or the Board, as appropriate. All communications directed to the Board, committee, or individual director that relate to non-financial matters (including, without limitation, purported or suspected violations of any law or regulation, our Code of Business Conduct and Ethics or other policies) will be forwarded to Masimo's Compliance Officer, and, if the Compliance Officer deems the matter to be a potentially significant violation of law, the Code of Business Conduct and Ethics, or company policy, the Compliance Officer will promptly and directly forward the communication to the Nominating, Compliance and Corporate Governance Committee.

INFORMATION REGARDING BOARD COMMITTEES

Our Board has established a standing Audit Committee, Compensation Committee, and Nominating, Compliance and Corporate Governance Committee to devote attention to specific subjects and to assist it in the discharge of the Board's responsibilities. All of these committees operate under a written charter adopted by our Board, each of which is available on our website at https://investor.masimo.com/governance/governance-documents/default.aspxunder 'Governance Documents.'

AUDIT RELATED MATTERS

AUDIT COMMITTEE'S PRE-APPROVAL POLICIES AND PROCEDURES

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

The Audit Committee has determined that the rendering of the services other than audit services by Grant Thornton LLP is compatible with maintaining the independent registered public accounting firm's independence.

AUDIT COMMITTEE REPORT

Our Audit Committee is composed of 'independent directors,' as determined in accordance with Nasdaq Listing Rule 5605(a)(2) and Rule 10A-3 of the Exchange Act. The Audit Committee operates pursuant to a written charter adopted by the Board, a copy of which may be viewed on our website at https://investor.masimo.com/governance/governance-documents/default.aspxunder 'Governance Documents.'

As described more fully in its charter, the purpose of the Audit Committee is to assist our Board with its oversight responsibilities regarding the integrity of our financial statements, assessing the independent registered public accounting firm's qualifications and independence and the performance of the persons performing internal audit duties for us and the independent registered public accounting firm. Management is responsible for the preparation, presentation and integrity of our financial statements as well as our financial reporting process, accounting policies, internal audit function, internal accounting controls and disclosure controls and procedures. The independent registered public accounting firm is responsible for performing an independent audit of our consolidated financial statements in accordance with generally-accepted auditing standards and issuing a report. The Audit Committee's responsibility is to monitor and oversee these processes. The following is the Audit Committee's report submitted to the Board for fiscal 2020.

The Audit Committee has:

•reviewed and discussed our audited financial statements with management and Grant Thornton LLP, the independent registered public accounting firm;

•discussed with Grant Thornton LLP the matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board and the SEC; and

•received from Grant Thornton LLP the written disclosures and the letter regarding their communications with the Audit Committee concerning independence as required by the applicable requirements of the Public Company Accounting Oversight Board and discussed Grant Thornton LLP's independence with them.

In addition, the Audit Committee has met separately with management and with Grant Thornton LLP as part of the committee's quarterly meetings.

Based on the review and discussions referred to above, the Audit Committee recommended to the Board that the audited financial statements be included in our Annual Report on Form 10-K for the year ended January 2, 2021 for filing with the SEC. The Audit Committee also has selected and engaged Grant Thornton LLP as Masimo's independent registered public accounting firm for the fiscal year ending January 1, 2022, and is seeking ratification of the selection by Masimo's stockholders.

Fiscal2020 Performance Highlights

The following represents a few financial and operational highlights of fiscal 2020 (these include GAAP and non-GAAP measures(1)):

Product Revenue (in millions) $1,144 Goal: $1,035M	Non-GAAP Product Revenue Growth(1) 22%	Non-GAAP EPS(1) ($ per diluted share) $3.60 Goal: $3.56	Non-GAAP EPS(1) (% growth) 12%

In 2020, we witnessed extremely challenging situations for patients and healthcare providers around the world related to the COVID-19 pandemic. We also witnessed incredible leadership, resilience and courage by many people in many walks of life, and in particular the frontline healthcare providers: our doctors, nurses, respiratory therapists, EMS professionals and others.

Within this tough environment, our global organization contributed to the critical solutions that were, and still are, required to manage this pandemic. In the midst of the pandemic, last year was also a milestone year for Masimo as our revenues exceeded $1 billion for the first time since our founding over 30 years ago. Today, we are even more committed to helping our customers overcome the persistent challenges related to this pandemic with an expanding portfolio of products to improve patient outcomes and reduce the cost of care.

We realized many significant achievements in 2020 such as the introduction of our Masimo SafetyNet™ system for enabling hospital-to-home monitoring while also growing the customer base for our Patient SafetyNet solution that enables hospitals to streamline workflow and improve patient care, especially where hospital staff were overwhelmed due to many COVID-19 patient admissions. Within Masimo, our dedicated team was nimble in its response to our customers in the face of significant demand for our products, while at the same time expanding our portfolio. This expansion included Radius-Tº™ continuous wearable thermometer, Centroid™ continuous wearable patient orientation and activity sensor, and Masimo SafetyNet-OPEN™ to help institutions open and stay open safely. We also completed three notable acquisitions, including the iSirona™ Connected Care business from NantHealth, TNI medical AG, and LiDCO Group Plc, which expands our technology portfolio into the large and growing markets for hospital automation, respiratory therapy and hemodynamic monitoring, respectively.

Our performance in 2020 demonstrates yet another year of strong execution towards our long-range plans and a commitment to reinvest in the business to drive growth and deliver long-term stockholder value.

Several widely accepted measures of operating performance reflect the strength of our fiscal 2020 financial performance on both an absolute and relative basis, as compared to other companies that comprised our fiscal 2020 compensation peer group, which included other publicly-traded companies classified as health care equipment and supplies companies in Global Industry Classification Standard Code 351010 (see '-Competitive Positioning' on page 58 of this Proxy Statement for a discussion of our fiscal 2020 compensation peer group). Such operating measures for the fiscal years ended nearest to January 2, 2021 were as follows:

Measures of Operating Performance	Masimo Performance	Percentile Ranking Versus Fiscal 2020 Compensation Peer Group Companies
Return on Equity	18.7%	72nd
Return on Capital	12.1%	82nd
Return on Assets	10.3%	85th
Total Revenue Growth	22%	89th
Operating Margin	22.3%	86th

We believe that our fiscal 2020 performance results reflect the continued attention and focus by our executive team on delivering financial results that reflect not only revenue growth, but also strong financial returns based on our assets, equity, and capital structure. In fact, our fiscal 2020 performance results placed Masimo above the 80th percentile of our compensation peer group for return on capital, return on assets, revenue growth and operating margin, with return on equity at the 72nd percentile. We believe that our strong operating performance measures relative to our compensation peer group further demonstrates the success of our executive team's efforts during fiscal 2020.

Results of Fiscal 2019 Compensation Stockholder Advisory Vote

At our 2020 Annual Meeting of Stockholders, we conducted a non-binding stockholder advisory vote on the fiscal 2019 compensation of our named executive officers (commonly known as a 'Say-on-Pay' vote). Our stockholders approved our Say-on-Pay proposal with approximately 88% of the votes cast in favor of the fiscal 2019 compensation of our named executive officers. While this represented an increase in support for our executive compensation program compared to our fiscal 2018 compensation program, our Board believes that it remains important to be responsive to feedback from our stockholders about our executive compensation program. During fiscal 2020, the Chairperson of our Compensation Committee and members of management were involved in more than 15 in-person or telephonic meetings with stockholders representing more than 45% of our outstanding shares. These discussions covered topics such as long-term strategy, financial and operating performance, risk management, executive compensation and governance practices. These discussions, together with our fiscal 2019 Say-on-Pay results, indicated support for our 2019 compensation program and influenced our decision to maintain a consistent overall approach for fiscal 2020 compensation.

Fiscal 2020 Executive Compensation Program

As previously noted, the Compensation Committee values the feedback we receive from our stockholders. In 2017, in response to feedback received from our stockholders, the Compensation Committee implemented certain changes to our executive compensation program, which carried forward into fiscal 2018, 2019 and 2020, and which continue to align the compensation of our executive officers with both short-term and long-term performance that supports our long-term business strategy. Although we do not provide detailed disclosure of our forward-looking performance metrics for competitive reasons, which is a commonly accepted practice, we do provide a detailed disclosure of our prior awards within '-Executive Compensation-Individual Compensation Elements' starting on page 59 of this Proxy Statement.

•Annual Cash Incentives - The annual cash incentive plan is designed to provide performance-based compensation that will be earned only upon achieving various pre-established levels of Company financial performance. For fiscal 2020, the Compensation Committee selected 2020 Adjusted Product Revenue(2) and 2020 Adjusted Non-GAAP EPS(2) as the performance measures for the funding percentages, each weighted equally, as the Compensation Committee believes these performance measures directly support both our short-term strategy and our long-term objective of creating sustainable stockholder value.

•LTI Compensation - Equity Awards - The Compensation Committee believed that a one-year performance period was appropriate for the 2017 PSU awards in light of the transition to our new 2017 Equity Incentive Plan. However, to further align the compensation of our executive officers with long-term performance, the Compensation Committee decided to extend the performance period for the 2018, 2019 and 2020 PSU awards from one year to three years. For example, the 2018 PSU awards vested in fiscal 2021, based on actual performance achieved in fiscal 2020. The performance objectives were established at the beginning of 2018, which required us to deliver improving financial results over the 3-year performance period (2018 through 2020) in order to achieve our financial objectives for fiscal 2020.

•Accordingly, the Compensation Committee granted LTI awards to our executive officers for fiscal 2020 consisting of the following mix of equity awards:

◦25% in the form of stock options that vest annually over a five year period; and

◦75% in the form of PSU awards that are earned, if at all, at the end of a three-year performance period based on our actual performance as measured against pre-established performance objectives. For the fiscal 2020 PSU awards, the Compensation Committee selected fiscal 2022 Adjusted Product Revenue(2) and fiscal 2022 Adjusted Non-GAAP Operating Margin(2) as the performance measures for the targeted PSU award percentages, each weighted equally.

Performance Stock Unit Awards

We continue to seek and value the opinions of our stockholders, as well as the insights gained from the discussions we have with specific stockholders. The Compensation Committee finds these discussions to be helpful as it considers and adopts compensation policies affecting our executive officers, including our NEOs. We will continue to consider the outcome of future Say-on-Pay votes, as well as feedback received throughout the year when making compensation decisions for our executive officers.

Fiscal 2020 NEO Compensation Highlights

The Compensation Committee took the following key actions for fiscal 2020 with respect to the compensation of our NEOs:

•Base Salaries - We increased the annual base salaries of our NEOs by 3.0%, which was consistent with the increases provided to our other employees as a whole. Please see 'Base Salary' on page 59 of this Proxy Statement for additional information.

•Annual Cash Incentives - Based on our Adjusted Product Revenue(2) and Adjusted Non-GAAP EPS(2)for fiscal 2020, we paid annual cash bonuses under our fiscal 2020 Executive Bonus Incentive Plan to our NEOs (other than our CEO) for fiscal 2020 ranging from $250,194 to $405,048, and an annual cash bonus to our CEO in the amount of $1,657,764.

•LTI Compensation - Equity Awards - In March 2020, we granted options to purchase shares of our common stock to each of our NEOs (other than our CEO) with a grant date fair value of ranging from $299,973 to $599,991, and an option to purchase shares of our common stock to our CEO with a grant date fair value in the amount of $2,999,999. In March 2020, we also granted PSU awards with a target grant date fair value ranging from $899,971 to $1,799,941 to our NEOs (other than our CEO) and a PSU award with a target grant date fair value of $8,999,887 to our CEO.

Total Target Compensation

We believe that our fiscal 2020 executive compensation was closely aligned with our stockholders' interests. While base salary and an annual cash bonus opportunity focused on the achievement of shorter-term goals, our equity awards, in the form of options to purchase shares of our common stock and PSU awards, provided for a longer-term compensation structure to focus attention on our long-term operating results and promote retention. Most of the fiscal 2020 annual compensation of our executive officers was directly tied, through performance-based annual cash bonuses and LTI compensation in the form of stock options and PSU awards, to the achievement of financial and operating results that increased stockholder value.

The following charts show the mix of our CEO's and, on average, each NEO's target total direct compensation for fiscal 2020, consisting of base salary, a target annual cash bonus opportunity and the grant date fair value of the equity awards granted during the year:

Total long-term incentive compensation =	81.0%	Total long-term incentive compensation =	66.0%
Total 'at risk' compensation =	92.2%	Total 'at risk' compensation =	80.2%

________________

(2) Non-GAAP financial measure - please see Appendix B to this Proxy Statement for a description of the adjustments and a reconciliation to the corresponding GAAP financial measure.

As illustrated above, the target total direct compensation opportunities of our NEOs are directly linked to our financial performance. We believe that our executive officers' interests were and continue to be aligned with those of our stockholders given that a substantial portion of their target total direct compensation was 'at-risk' and variable commensurate with our financial performance. We also believe that our executive compensation program appropriately emphasized performance-based compensation that rewarded our executive officers for delivering financial, operational and strategic results that met or exceeded pre-established goals through our annual cash bonus plan and the PSU awards under our LTI compensation plans. In addition, we further aligned the interests of our executive officers with those of stockholders and our long-term interests through executive stock ownership requirements. As of the date of this Proxy Statement, each of our executive officers to whom such stock ownership requirements are applicable was in compliance with such requirements.

Executive Compensation Policies and Practices

We endeavor to maintain sound executive compensation policies and practices, including compensation-related corporate governance standards, consistent with our executive compensation philosophy. During fiscal 2020, we maintained the following executive compensation policies and practices, including both policies and practices we have implemented to drive performance and policies and practices that either prohibit or minimize behaviors that we do not believe serve our stockholders' long-term interests:

What We Do

üMaintain an Independent Compensation Committee. The Compensation Committee consists solely of independent directors who establish our compensation practices.

üCompensation Committee Retains an Independent Compensation Advisor. The Compensation Committee has engaged its own compensation consultant to provide information, analysis and other advice on executive compensation independent of management.

üAnnual Executive Compensation Review.At least once a year, the Compensation Committee conducts a review of our compensation strategy.

üCompensation At-Risk - Pay For Performance. Our executive compensation program is designed so that a significant portion of our executive officers' compensation is 'at-risk' based on corporate performance, to align the interests of our executive officers and stockholders.

üAnnual Compensation-Related Risk Assessment.The Compensation Committeeconsiders our compensation-related risk profile to ensure that our compensation plans and arrangements do not create inappropriate or excessive risk and are not reasonably likely to have a material adverse effect on the Company. The Compensation Committee has determined that there are no risks arising from our compensation policies and practices for our employees that are reasonably likely to have a material adverse effect on the Company.

üMulti-Year Vesting Requirements and Performance Periods. To align the interests of our executive officers and stockholders, the time-based stock-option awards granted to our executive officers vest over a five-year period. In 2020, we granted our executive officers PSU awards that will be earned, if at all, at the end of a three-year performance period based on our actual performance as measured against pre-established performance objectives relating to fiscal 2022 Adjusted Product Revenue(2) and fiscal 2022 Adjusted Non-GAAP Operating Margin(2).

üCompensation Recovery ('Clawback') Policy.We have adopted a compensation recovery ('clawback') policy, which enables our Board to recover incentive compensation (including gains from equity awards) from our current and former executive officers that is based on erroneous data, received during the three-year period preceding the date on which we become required to prepare an accounting restatement; and is in excess of what would have been paid if calculated under the restatement.

_____________________________________

(2) Non-GAAP financial measure - please see Appendix B to this Proxy Statement for a description of the adjustments and a reconciliation to the corresponding GAAP financial measure.

üStock Ownership Policies.We have adopted stock ownership policies for our executive officers and the non-employee members of our Board under which they must accumulate and maintain, consistent with the terms of our stock ownership policy, shares of our common stock. For additional information, see 'Ownership Of Our Stock - Stock Ownership Policies' starting on page 85 of this Proxy Statement.

üAnnual Stockholder Advisory Vote on Named Executive Officer Compensation.We conduct an annual stockholder advisory vote on the compensation of our NEOs. The Compensation Committee considers the results of this advisory vote during the course of its deliberations on our executive compensation program.

üStockholder Engagement that Includes our Compensation Committee Chairperson. We engage with our stockholders on executive compensation matters and include our Compensation Committee Chairperson in these engagement activities.

What We Do Not Do

ûNo Guaranteed Bonuses.We do not provide guaranteed bonuses to our executive officers.

ûNo Special Executive Retirement Plans.We do not currently offer, nor do we have plans to offer, defined benefit pension plans or any non-qualified deferred compensation plans or arrangements to our executive officers other than the plans and arrangements that are available to all employees. Our executive officers are eligible to participate in our defined contribution plan under Section 401(k) of the Internal Revenue Code of 1986, as amended (the 'Code'), on the same basis as our other employees.

ûNo Hedging; Pledging Requires Pre-Approval.We prohibit our employees, including our executive officers, and the non-employee members of our Board from hedging our equity securities. In addition, all pledging of our equity securities by our executive officers and members of our Board must be pre-approved by the Compensation Committee and, as a condition to pre-approving any pledge of our equity securities, the executive officer or member of our Board seeking to pledge securities must clearly demonstrate his or her financial capacity to repay any loan for which securities will be pledged as collateral without resort to the securities to be pledged.

ûNo Tax Payments on Perquisites.We do not provide any tax reimbursement payments (including 'gross-ups') to our executive officers on any perquisites or other personal benefits.

ûNo Gross-Up Payments on Post-Employment Compensation Arrangements.We do not provide any tax reimbursement payments (including 'gross-ups') on payments or benefits contingent upon a change in control of the Company.

ûNo Stock Option Re-pricing. We do not permit options to purchase shares of our common stock to be re-priced to a lower exercise price without the approval of our stockholders. We have never repriced our stock options.

ûNo Evergreen Provisions. The 2017 Equity Plan does not contain an annual 'evergreen' provision that increases the number of shares available for issuance each year. The 2017 Equity Plan authorizes a fixed number of shares, so that stockholder approval is required to increase the maximum number of shares that may be issued subject to awards under the 2017 Equity Plan.

COMPENSATION PHILOSOPHY AND OBJECTIVES

The primary objective of our executive compensation program is to attract and retain a talented, entrepreneurial and creative team of executives who will provide leadership for our success in driving our technologies and products to the broadest number of patients, and in turn, creating sustainable long-term value. We seek to accomplish this objective in a way that is aligned with the long-term interests of our stockholders.

Compensation Philosophy

We operate within a very complex business environment, which requires a very strong management team. Our business model requires our management team to be adept at developing competitive products and sales/marketing strategies to support multiple customers, including hospitals, alternate care facilities and original equipment manufacturers within multiple geographies. Many of our competitors have substantially greater capital resources, larger customer bases and larger sales forces than we do, and have ties with group purchasing organizations and other purchasers that are stronger than ours. In addition, the medical device industry is characterized by rapid product development and technological advances, which require our management team to be adept at managing these key areas of the business.

As a result, the Compensation Committee believes that it is critical to attract, develop and retain a highly-qualified management team with the experience, knowledge, expertise and vision capable of not only operating, but also excelling, in this complex and competitive business environment, including competing against larger competitors and developing and commercializing new products, new and improved technologies and new applications for our existing technologies.

Compensation Objectives and Program Design

Our executive compensation program is intended to help us achieve and foster a goal-oriented, highly-motivated management team with a clear understanding of our business objectives and shared corporate values. To this end, the Compensation Committee believes that our executive compensation program should provide compensation that:

•attracts and retains the best executive talent;

•appropriately aligns our business objectives and stockholder interests;

•maintains a reasonable balance across types and purposes of compensation, particularly with respect to fixed compensation objectives, short-term and long-term performance-based objectives and retention objectives;

•motivates our executive officers to achieve our annual and long-term strategic goals and rewards performance based on the attainment of such goals;

•appropriately considers risk and reward in the context of our business environment and long-range business plans;

•recognizes individual value and contributions to our success;

•considers but does not exclusively rely upon competitive market data; and

•supports our succession planning objectives.

We seek to achieve these objectives in a way that is consistent with our long-term interests and our stakeholders, including our stockholders and employees. We structure the annual compensation of our executive officers, including our NEOs, using three principal elements: base salary, annual cash incentive opportunities and LTI compensation opportunities in the form of equity awards. While the pay mix may vary from year to year, the ultimate goal is to achieve our compensation objectives as described above. The relationships between each element and such compensation objectives are as follows:

Type	Component	Purpose	Key Features
Fixed Compensation	Base Salary	Provide competitive, fixed compensation to attract and retain the best possible executive talent	l	Cash-based
	l	Reviewed annually, changes effective July
l	Takes into account level of responsibility, time in role, performance and the ability to replace the individual
Performance-Based	Cash Incentives	Align executive compensation with our corporate strategies and business objectives; promote the achievement of key strategic and financial performance measures by linking annual cash incentives to the achievement of corporate performance goals	l	Cash-based
Compensation		l	Reviewed annually, paid in March
l	Performance-based and not guaranteed
l	Drive the achievement of key business results on an annual or multi-year basis
Equity Awards	Align executive compensation with our corporate strategies, and business objectives, motivate the Company's officers to create sustainable long-term value for our stockholders and achieve other business objectives, encourage stock ownership by the Company's officers in order to align their financial interests with the long-term interest of stockholders	l	Equity-based
	l	Attract and retain talent
l	Multi-year performance period and not guaranteed
l	Combination of:
l Performance-based restricted stock units
l Time-based stock options
l	Based on performance goals tied to determined financial metric approved by the Board (PSUs)
l	Drive the achievement of key long-term business results on a multi-year basis

GOVERNANCE OF EXECUTIVE COMPENSATION PROGRAM

Role of Compensation Committee

The Compensation Committee discharges the responsibilities of our Board relating to the compensation of our executive officers. The Compensation Committee consists of directors who are 'independent' directors as required by the Nasdaq listing standards and Exchange Act Rule 10C-1, and 'non-employee directors' for purposes of Exchange Act Rule 16b-3. During fiscal 2020, the Compensation Committee was comprised of Messrs. Harkin, Mikkelson and Reynolds (the current Chairperson of the Compensation Committee). Mr. Cohen joined the Compensation Committee effective April 1, 2021. Mr. Harkin served on the Compensation Committee until April 1, 2021.

The Compensation Committee has responsibility for overseeing our compensation and benefits policies generally, and overseeing, evaluating and approving the compensation plans, policies, and programs applicable to our CEO, as well as our other executive officers. In carrying out its responsibilities, the Compensation Committee evaluates our compensation policies and practices with a focus on the degree to which these policies and practices reflect our executive compensation philosophy, develops recommendations, makes decisions that it believes advances our philosophy and reviews the performance of our executive officers when making decisions with respect to their compensation.

The Compensation Committee reviews the base salary levels, annual cash bonus opportunities, and LTI compensation opportunities of our executive officers annually or more frequently as warranted. In making decisions about the compensation of our executive officers, the Compensation Committee relies on its general experience and subjective considerations of various factors, including the following:

•our performance against the financial, operational and strategic objectives established by the Compensation Committee and our Board;

•each individual executive officer's skills, experience, and qualifications relative to other similarly-situated executives at the companies in our compensation peer group;

•the scope of each executive officer's role compared to other similarly-situated executives at the companies in our compensation peer group;

•the performance of each individual executive officer, based on a subjective assessment of his or her contributions to our overall performance, ability to lead his or her business unit or function, and work as part of a team, all of which reflect our core values;

•compensation parity among our executive officers;

•our financial performance relative to our compensation and performance peers;

•feedback from our investor outreach programs; and

•with respect to his direct reports, the recommendations of our CEO.

These factors provide the framework for compensation decision-making and final decisions regarding the compensation opportunity for each executive officer. No single factor is determinative in setting pay levels, nor was the impact of any factor on the determination of pay levels quantifiable.

The Compensation Committee also considers the potential risks in our business when designing and administering our executive compensation program. We believe our balanced approach to performance measurement and pay delivery works to avoid misaligned incentives for individuals to undertake excessive or inappropriate risk.

The Compensation Committee does not engage in formal benchmarking against other companies' compensation programs or practices to establish our compensation levels or make specific compensation decisions with respect to our executive officers. Instead, in making its determinations, the Compensation Committee reviews information summarizing the compensation paid at a representative group of peer companies, to the extent that the executive positions at these companies are considered comparable to our positions and informative of the competitive environment, as well as more broad-based compensation surveys to gain a general understanding of market compensation levels.

Role of Management

In discharging its responsibilities, the Compensation Committee works with members of our management team, including our CEO. The management team assists the Compensation Committee by providing information on the Company's performance, as well as individual performance, market data and management's perspective and recommendations on compensation matters.

The Compensation Committee solicits and reviews our CEO's recommendations and proposals with respect to adjustments to annual cash compensation, LTI compensation opportunities, program structures and other compensation-related matters for our executive officers (other than with respect to his own compensation). The Compensation Committee reviews and discusses these recommendations and proposals with our CEO and uses them as one factor in determining and approving the compensation for our executive officers. However, when the Compensation Committee sets the compensation for our CEO, he recuses himself from discussions regarding his own compensation. The Compensation Committee does not delegate any of its functions to others in deciding executive compensation.

Role of Compensation Consultant

The Compensation Committee engages an independent compensation consultant to assist it by providing information, analysis and other advice relating to our executive compensation program and the decisions resulting from its executive compensation review. The compensation consultant serves at the discretion of the Compensation Committee, which reviews the engagement annually.

Since October 2016,the Compensation Committee has retained Compensia, a national compensation consulting firm, to serve as its compensation advisor. During fiscal 2020, Compensia provided the following services to the Compensation Committee:

•consulting with the Compensation Committee chairperson and other members between Compensation Committee meetings;

•providing competitive market data based on the compensation peer group for our executive officer positions and evaluating how the compensation we pay our executive officers compares both to our performance and to how the companies in our compensation peer group compensate their executives;

•reviewing and analyzing the base salary levels, annual cash bonus opportunities, and LTI compensation opportunities of our executive officers;

•assessing executive compensation trends within our industry, and providing updates on corporate governance and regulatory issues and developments;

•reviewing the Compensation Discussion & Analysis in this Proxy Statement; and

•assessing compensation risk to determine whether our compensation policies and practices are reasonably likely to have a material adverse impact on the Company.

Compensia did not provide any services to us other than the consulting services to the Compensation Committee.

The Compensation Committee regularly reviews the objectivity and independence of the advice provided by its compensation consultant to the Compensation Committee on executive compensation matters. During fiscal 2020, the Compensation Committee considered the six specific independence factors adopted by the SEC and Nasdaq in past years, determined that Compensia was still an independent advisor, and concluded that its work did not raise any conflicts of interest. During fiscal 2020, the total fees payable to Compensia were approximately $72,000.

Competitive Positioning

For purposes of comparing our executive compensation against the competitive market (Industry - health care equipment and supplies; Global Industry Classification Standard code 351010), the Compensation Committee reviews and considers the compensation levels and practices of a group of comparable companies. The companies in this compensation peer group for fiscal 2020 were approved on February 28, 2020on the basis of their similarity to us in size, in terms of annual revenue and market capitalization.

In determining the fiscal 2020 compensation peer group, the Compensation Committee tried to select peer companies that resulted in us being near the median of the group in terms of both revenue and market capitalization. Our compensation peer group for fiscal 2020 was as follows:

•ABIOMED, Inc.	•Hill-Rom Holdings, Inc.	•NuVasive, Inc.
•Align Technology, Inc.	•Hologic, Inc.	•OSI Systems, Inc.
•Cooper Companies, Inc.	•Insulet	•ResMed, Inc.
•DENTSPLY SIRONA, Inc.	•ICU Medical, Inc.	•Teleflex, Inc.
•Dexcom, Inc.	•Integra LifeSciences Holdings Corp.	•Varian Medical Systems, Inc.
•Globus Medical, Inc.	•LivaNova PLC	•West Pharmaceutical Services, Inc.
•Haemonetics Corp.	•Merit Medical Systems, Inc.

The companies included in the compensation peer group had median revenues of $1.4 billion, ranging from approximately $700 million to approximately $4.0 billion, based on the four fiscal quarters ended nearest to December 26, 2019, representing approximately 0.76 times to 4.4 times our last four quarters of revenue of approximately $913 million as of such date. In addition, the compensation peer group had a median market capitalization of $9.7 billion, ranging from approximately $1.6 billion to $21.7 billion, as of December 26, 2019, and representing approximately 0.2 times to 2.6 times our market capitalization of $8.3 billion as of such date.

To analyze the compensation practices of the companies in our compensation peer group, Compensia gathered data from public filings (primarily proxy statements). This market data was then used as a general external reference point for the Compensation Committee in assessing our current compensation levels for executive base salaries, annual cash bonus opportunities and total equity compensation targets.

The Compensation Committee reviews our compensation peer group periodically and makes adjustments to its composition as it considers necessary and appropriate, taking into account changes in both our business and the businesses of the companies in the peer group.

INDIVIDUAL COMPENSATION ELEMENTS

The specific elements of our executive compensation program for fiscal 2020 included base salary, annual cash incentive opportunities, LTI compensation opportunities in the form of equity awards, welfare and health benefits and post-employment compensation arrangements. We use short-term compensation, such as base salary and annual cash bonus opportunities, to motivate and reward our executive officers. We believe that, in addition to base salaries and annual cash bonus opportunities, LTI compensation opportunities, which in fiscal 2020 were provided in the form of options to purchase shares of our common stock and PSU awards that could be earned and settled for shares of our common stock, are an effective tool in attracting and retaining strong executive talent. A full description of each compensation element follows:

Base Salary

Base salary represents the fixed portion of the compensation of our executive officers, including our NEOs, and is an important element of compensation intended to attract and retain highly-talented individuals. Generally, we use base salary to provide each executive officer with a specified level of cash compensation during the year with the expectation that he or she will perform his or her responsibilities to the best of his or her ability and in our best interests.

Generally, we establish the initial base salaries of our executive officers through arm's-length negotiation at the time we hire the individual executive officer, taking into account his or her position, qualifications, experience, prior salary level and the base salaries of our other executive officers. Thereafter, the Compensation Committee reviews the base salaries of our executive officers annually and makes adjustments to base salaries as it determines to be necessary or appropriate.

During fiscal 2020, the Compensation Committee reviewed the base salaries of our executive officers, including the NEOs, taking into consideration a competitive market analysis and the recommendations of our CEO, as well as the other factors described above. Following this review, the Compensation Committee approved a 3.0% base salary increase for executive officers, which was consistent with the increases provided to our other employees as a whole. Please see 'Base Salary' on page 60 of this Proxy Statement for additional information.

The base salaries of the NEOs for fiscal 2020 were as follows:

Name	Base Salary as of December 28, 2019	Base Salary as of January 2, 2021	Percentage Change
Joe Kiani	$	1,125,510	$	1,159,275	3.0	%

Annual Cash Incentive

In March 2020, the Compensation Committee approved the terms of the 2020 Executive Bonus Incentive Plan under which our NEOs are eligible to receive a cash bonus based on the achievement of Company performance goals. At the beginning of the year, the Compensation Committee approves funding percentages that include payout scenarios for various levels of Company financial performance. For 2020, the Compensation Committee selected Adjusted Product Revenue(2) and Adjusted Non-GAAP EPS(2) as the performance measures for the funding percentages, each weighted equally, as the Compensation Committee believes these performance measures directly support both our short-term strategy and our long-term objective of creating sustainable stockholder value.

•2020 Adjusted Product Revenue(2): The target goal for 2020 Adjusted Product Revenue(2) was $1,035 million, which reflected growth of 10.5% over the prior year period.

•2020 Adjusted Non-GAAP EPS(2):The target goal for 2020 Adjusted Non-GAAP EPS(2) was $3.56, which reflected growth of 10.6% over the prior year period.

For purposes of calculating the performance achievement and funding percentages for 2020, the Compensation Committee determined that the performance measures would be adjusted to exclude the impact of foreign currency fluctuations. The purpose of these adjustments is to ensure the measurement of performance reflects factors that management can directly control and that payout levels are not artificially inflated or impaired by factors unrelated to the ongoing operations of the business.

The table below sets forth the Adjusted Product Revenue(2) and Adjusted Non-GAAP EPS(2) performance goals and funding percentages at the threshold, target and maximum funding levels for 2020, as well as the actual performance results:

Metric	Weighting	Target Goal	Actual Performance	Achievement %(1)	Payout %(1)	Weighted Result
Threshold	Maximum	Actual Performance	Minimum	Maximum	Actual Performance
Adjusted Product Revenue	50%	$1,035	$1,138.9	90%	110%	110%	0%	200%	200%	143%
Adjusted Non-GAAP EPS	50%	$3.56	$3.51	90%	110%	99%	0%	200%	86%

______________

(1) Pursuant to the 2020 Executive Bonus Incentive Plan, payouts for achievement levels between the threshold and maximum were based on a linear interpolation between points along the fundingcurve.

___________________________

(2)Non-GAAP financial measure - please see Appendix B to this Proxy Statement for a description of the adjustments and a reconciliation to the corresponding GAAP financial measure.

For 2020, we reported Adjusted Product Revenue(2) of $1,143 million and Adjusted non-GAAP EPS(2) of $3.60. Excluding the impact of foreign exchange fluctuations versus the plan, we achieved Adjusted Product Revenue(2) of $1,138.9 million and Adjusted Non-GAAP EPS(2) of $3.51. Based on the funding table for the 2020 bonus plan, the Compensation Committee approved a funding percentage of 143% of target for the 2020 Executive Bonus Incentive Plan, which is the weighted average of the actual performance percentages achieved and funded for Adjusted Product Revenue(2) and Adjusted Non-GAAP EPS(2) for fiscal 2020.

The following is a summary of the target annual cash bonus opportunities, the actual annual 2020 bonus awards for the NEOs and a comparison relative to their target awards:

Long-Term Incentive ('LTI') Compensation - Equity Awards

The Compensation Committee believes LTI compensation in the form of equity awards provides an incentive for our executive officers, including our NEOs, to focus on driving increased stockholder value over a multi-year period, serves as a reward for appreciation in our stock price and long-term value creation, and enables us to achieve our retention objectives.

Furthermore, the Compensation Committee believes that stock options and PSU awards are effective tools for increasing long-term stockholder value for several reasons. In the case of stock options, they only have value to the extent that the market price of our common stock price appreciates above the option exercise price, thereby driving value over the vesting period. In the case of PSU awards, the value of the award fluctuates based on our achievement of pre-established performance objectives over the multi-year performance period.

To directly align LTI awards with stockholder value, the Compensation Committee awarded 2020 LTI awards to our NEOs in the form of stock options (25% of total target award value) and PSUs (75% of target award value). The following is a summary of the annual 2020 LTI awards for the NEOs.

______________

(1)The 2020 stock option awards were granted on March 12, 2020.

(2)Amounts set forth in this column reflect the grant date fair value of the option awards, computed in accordance with ASC Topic 718. All of these amounts reflect certain assumptions with respect to the option awards and do not necessarily correspond to the actual value that will be recognized by our NEOs. The actual value, if any, that may be realized from an option award is contingent upon the satisfaction of the conditions to vesting of that award, and upon the excess of the stock price over the exercise price, if any, on the date the option award is exercised. See Note 18 of the Notes to Financial Statements included in our Annual Report on Form 10-K for the fiscal year ended January 2, 2021 that was filed with the SEC on February 23, 2021 for a discussion of the assumptions made in determining the grant date fair value of the stock options.

(3)Reflects the target number of shares subject to PSUs, assuming all performance goals and other requirements are met. As described below, the PSUs earned will range from 50% to 200% of target based on the achievement of performance goals, which vest in the form of shares of our common stock following the conclusion of the three-year performance period.

(4)The 2020 PSU awards were granted on March 12, 2020. The number of shares was determined by dividing the economic value by the closing stock price per share of $179.42 on the date of grant. Any calculation that results in a fractional share was rounded down to the nearest whole share.

The table below sets forth the 2020 LTI award type, purpose, performance goals and vesting terms.

LTI Award Type	Purpose	Performance Goal(s)	Vesting Terms
Stock options (25% of total target value)	Retain and reward executives for driving long-term stockholder value	Continuous service with the Company	Vest annually over a five year period (20% per year)
PSUs (75% of total target value)	Retain and reward executives for the achievement of multi-year performance goals	2022 Adjusted Product Revenue(1) and 2022 AdjustedNon-GAAP Operating Margin(1)	Vest in 2023 with opportunity that ranges from 50%-200%

The Compensation Committee selected 2022 Adjusted Product Revenue(1) and Adjusted Non-GAAP Operating Margin(1) as the primary performance metrics for the 2022 PSU awards because it believes management should be incentivized to deliver multi-year revenue results and operating margin expansion that drives long term shareholder value. Furthermore, the Compensation Committee believes that it has set challenging, yet attainable, forward-looking 2022 Adjusted Product Revenue(1) and Adjusted Non-GAAP Operating Margin(1) goals.

The Compensation Committee believes that the current LTI equity award structure focuses our NEOs on driving increased stockholder value over a multi-year period and enables us to achieve our retention objectives, while maintaining a conservative approach to overall share usage. As a result, our company-wide equity burn rate was low in 2016, 2017, 2018 and 2019 and continued to decline even further in 2020.

Prior PSU Award Payouts

The 2018 PSU awards vested at the end of a three-year performance period on February 22, 2021 based on actual performance against pre-established performance objectives. The Compensation Committee selected fiscal 2020 Adjusted Product Revenue(1) and fiscal 2020 Adjusted Non-GAAP Operating Margin(1)as the performance measures for the targeted PSU award percentages, each weighted equally.

•2020 Adjusted Product Revenue(1):The target goal for 2020 Adjusted Product Revenue(1) was $960 million, which reflected a compound annual growth rate (CAGR) of 9.2% over the 3-year performance period.

•2020 Adjusted Non-GAAP Operating Margin(1):The target goal for 2020 Adjusted Non-GAAP Operating Margin(1) was 24.0%, which reflected a cumulative operating margin improvement of 540 basis points over the 3-year performance period.

The table below sets forth the Adjusted Product Revenue(1) and Adjusted Non-GAAP Operating Margin(1) performance goals and funding percentages at the threshold, target and maximum funding levels, as well as the actual performance results:

Metric	Weighting	Target Goal	Actual Performance	Achievement %	Payout %	Weighted Result
Threshold	Maximum	Actual Performance	Minimum	Maximum	Actual Performance
Adjusted Product Revenue	50%	$960	$1,143.7	90%	110%	119%	50%	200%	200%	141%
Adjusted Non-GAAP Operating Margin	50%	24.0%	23.1%	90%	110%	96%	50%	200%	82%

Welfare and Health Benefits

Our NEOs participate in our employee benefit plans on the same terms as all of our other eligible employees.

We maintain a tax-qualified Code Section 401(k) defined contribution plan in which all of our employees, including our executive officers, who satisfy certain eligibility requirements, including requirements relating to age and length of service, are entitled to participate. Employees may contribute their own funds on a pre-tax basis.

The plan permits us to make matching contributions and we have historically provided employer contributions that match eligible employee contributions ('employer matching contributions'), generally limited to 3% of the compensation that can be taken into account for this purpose under federal law.

Employer matching contributions vest 50% when an employee has been employed for two years, and vest an additional 25% for each additional year of service until fully vested after four years of eligible employment.

In addition, we provide health care, dental, vision and life insurance, health savings account ('HSA') employer contributions, an employee assistance plan and both short-term and long-term disability, accidental death and dismemberment benefits to all full-time employees. These benefits are subject to applicable laws and at benefit levels that we believe are generally consistent with the benefits of companies with which we compete for talent.

______________

(1) Non-GAAP financial measure - please see Appendix A to this Proxy Statement for a description of the adjustments and a reconciliation to the corresponding GAAP financial measure.

Perquisites and Other Personal Benefits

Generally, we provide perquisites and other personal benefits to our executive officers, including our NEOs, in situations where we believe it is appropriate to assist an individual in the performance of his or her duties, to make our executive officers more efficient and effective and for recruitment and retention purposes.

In addition, under the Amended CEO Agreement (as defined below), we reimburse our CEO for all reasonable travel and lodging expenses, which include travel and hospitality expenses for first class travel and accommodations, including travel by private or chartered aircraft, for his family and household members if they accompany him during business travel. Our Board believes that these arrangements are appropriate because of the extensive travel requirements of our CEO's position.

We also have established a security program for our CEO that provides physical and personal security services as they may, from time to time, be deemed necessary. This security program is not limited to providing security services at business facilities or functions or during business-related travel and may include providing security services at his residences and during personal travel. Our Board does not consider any of these security services to be a personal benefit as the requirement for this occasional security is directly the result of his role as our CEO. As our CEO, Mr. Kiani's personal safety is vital to our continued success. We may also provide security services for other executive officers from time to time on an as-needed basis.

We own one aircraft to facilitate the business travel of our executive officers and certain other employees. In general, our employees are not permitted to use the aircraft for personal travel. In fiscal 2017, we entered into an aircraft time share agreement with Mr. Kiani, pursuant to which we have agreed to make our aircraft available to Mr. Kiani for lease on a time sharing basis. Under this agreement, Mr. Kiani reimburses us for incremental costs incurred in connection with his personal use of our aircraft, in accordance with Federal Aviation Administration requirements.

We have reported the actual amounts that we have paid for our CEO's family and household members to accompany him during his business travel and for his security arrangements that were not security arrangements provided at our business facilities in the 'All Other Compensation' column in the Fiscal 2020 Summary Compensation Table in this Proxy Statement.

Post-Employment Compensation

Each of our NEOs, other than our CEO, is eligible to participate in our 2007 Severance Protection Plan (the 'Severance Plan') pursuant to a written severance agreement that they have executed with us. The Severance Plan provides these NEOs with specified payments and benefits in the event of certain terminations of employment or a change in control of Masimo or both. Our CEO's post-employment compensation arrangements are set forth in the Amended CEO Agreement and are described in the section entitled 'Employment Arrangements with Named Executive Officers - Employment Agreement with Mr. Kiani' starting on page 75 of this Proxy Statement.

We believe that having in place reasonable and competitive post-employment compensation arrangements is essential to attracting and retaining highly-qualified executive officers. Our post-employment compensation arrangements are designed to provide reasonable compensation to executive officers who leave the Company under certain circumstances to facilitate their transition to new employment. Further, we seek to mitigate any potential employer liability and avoid future disputes or litigation by requiring a departing executive officer to sign a separation and release agreement acceptable to us as a condition to receiving post-employment compensation payments or benefits.

We also believe that these arrangements are designed to align the interests of our executive officers and our stockholders when considering our long-term future. The primary purpose of these arrangements in the case of a change in control of the Company is to keep our most senior executive officers focused on pursuing all corporate transaction activities that are in the best interests of our 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. Further, we believe that these arrangements are necessary to offer compensation packages that are competitive with the market.

For information on the employment arrangements for our CEO and other NEOs, as well as an estimate of the potential payments and benefits payable under these arrangements as of the end of fiscal 2020, see '-Employment Arrangements with Named Executive Officers' in this Proxy Statement.

OTHER COMPENSATION POLICIES AND PRACTICES

Equity Awards Grant Policy

Equity awards granted to newly-hired employees are effective as of the later of the date the individual commences work or service with us or the grant approval date. Equity awards granted to existing employees and others providing services to us are effective as of the grant approval date. The terms of each equity award, including the date of grant, the corresponding exercise, purchase or base price, the vesting conditions, the term of such award, and the number of shares of our common stock subject to such award, as applicable, are approved by our Board, the Compensation Committee, or the non-officer equity award committee (as defined in the policy), as applicable. In addition, the exercise price for options to purchase shares of our common stock may not be less than the fair market value of our common stock as of the close of business on the effective date of the option.

Compensation Recovery ('Clawback') Policy

We maintain a compensation recovery ('clawback') policy that provides that in the event we are required to restate our financial statements as a result of 'material noncompliance' with the financial reporting requirements under the securities laws, we will recover from our current and former executive officers any incentive-based compensation (including stock options) that is:

•based on erroneous data;

•received during the three-year period preceding the date on which we become required to prepare an accounting restatement; and

•in excess of what would have been paid if calculated under the restatement.

We intend to review the terms of our policy once the SEC adopts final regulations implementing Section 954 of the Dodd-Frank Wall Street Reform and Consumer Protection Act and, if necessary, will revise our policy to conform to such regulations.

Policy Prohibiting Tax 'Gross-Up' Payments

We maintain a policy governing the inclusion of tax 'gross-up' provisions in agreements with our executive officers. Under this policy, the Compensation Committee will not approve any employment or other agreement or arrangement with any of our executive officers that includes a tax 'gross-up' or similar provision that would require payments by us to an executive officer be made in the full amount, free of any deductions or withholdings, and without exercising any right of set-off, in connection with a change in control of the Company. Our policy also provides that the Compensation Committee will not approve an amendment to extend the term of any current employment or other agreement or arrangement between us and any executive officer if such agreement or arrangement includes a tax 'gross-up' or similar provision. Currently, we have no agreements or arrangements in place with any executive officer that require or provide for a tax 'gross-up' or similar payment.

Under our Severance Plan in which our NEOs other than our CEO participate, the plan administrator has the right to reduce any change in control severance payment or benefits payable to an executive officer to avoid triggering any 'excess parachute payments' under Sections 280G and 4999 of the Code.

Hedging and Pledging Policies

Our Insider Trading Policy prohibits our employees, including our executive officers, and the non-employee members of our Board from engaging in 'short sales' of our equity securities and from engaging in hedging transactions involving our equity securities. Further, our Insider Trading Policy restricts our employees, including our executive officers, and the non-employee members of our Board from pledging our equity securities as collateral for a loan or otherwise unless the transaction is pre-cleared by our Insider Trading Compliance Officer. Further, as a condition of pre-approving any pledge of our equity securities, the executive officer or member of our Board seeking to pledge securities must clearly demonstrate his or her financial capacity to repay any loan for which securities will be pledged as collateral without resort to the securities to be pledged.

As of April 1, 2021, an aggregate of 400,000 shares of our common stock owned by a family trust and beneficially owned by our CEO were pledged as collateral for a personal loan. In addition to obtaining pre-clearance from our Insider Trading Compliance Officer, our CEO sought and received the approval of the Compensation Committee prior to entering into this transaction in 2013. When requesting such pre-clearance, Mr. Kiani explained that, without the ability to pledge these shares, certain of his family's financial planning objectives would need to be satisfied through the sale of shares of Masimo common stock held by his family trust and that he did not want to diminish his shareholdings. The Compensation Committee considered Mr. Kiani's request and, as part of that consideration, noted that his beneficial stock ownership in the Company, even without taking into account the pledged shares, would still greatly exceed the number of shares that Mr. Kiani would be required to hold under our stock ownership policy. The Compensation Committee concluded that continued ownership of the pledged shares by Mr. Kiani's family trust further aligned Mr. Kiani's interests with the long-term interests of our stockholders.

In light of these facts, the Compensation Committee concluded that approving the pledge was consistent with stockholder interests.

TAX AND ACCOUNTING CONSIDERATIONS

Deductibility of Executive Compensation

Generally, Section 162(m) of the Code ('Section 162(m)') disallows public companies a tax deduction for federal income tax purposes of compensation in excess of $1 million paid to their chief executive officer, the chief financial officer and the three other most highly-compensated executive officers in any taxable year. In making compensation decisions, the Compensation Committee considered the potential effects of Section 162(m) on the compensation paid our executive officers who are subject to the deduction limit (the 'covered executives'). The exemption from Section 162(m)'s deduction limit for performance-based compensation was generally repealed for taxable years beginning after December 31, 2017, such that compensation paid to our covered officers in excess of $1 million will generally not be deductible unless it qualifies for transition relief applicable to certain arrangements in place as of November 2, 2017.

To maintain flexibility in compensating the NEOs in a manner designed to promote varying corporate goals, the Compensation Committee has not adopted a policy that all compensation payable to the covered executives must be deductible for federal income tax purposes. Accordingly, the Compensation Committee may, in its judgment, approve compensation for our executive officers that does not comply with an exemption from the deduction limit when it believes that such compensation is in the best interests of the Company and our stockholders.

The Compensation Committee believes that stockholder interests are best served by not restricting the Compensation Committee's discretion and flexibility in structuring compensation programs, even though such programs may result in non-deductible compensation expenses.

Accounting for Stock-Based Compensation

We follow ASC Topic 718 for our stock-based compensation awards. ASC Topic 718 requires us to measure the compensation expense for all share-based payment awards granted to our employees and the non-employee members of our Board, including options to purchase shares of our 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.

To calculate the fair value of options to purchase shares of our common stock, we use the Black-Scholes-Merton option pricing model which requires the input of several subjective assumptions. These assumptions include estimating the length of time recipients will retain their vested options before exercising them, the estimated volatility of our stock price over the expected option term, and the number of shares of our common stock subject to options that will ultimately be forfeited prior to meeting their vesting requirements. The fair value of the options granted to our employees and the non-employee members of our Board are expensed over the requisite service period of each option, which is the vesting period, using a straight-line attribution method.

The fair value of RSU awards is calculated based upon the closing market price of our common stock on the date of the grant or any 'modification' to the grant, as that term is defined under ASC Topic 718. The fair value of the time-based RSU awards granted to our employees and the non-employee members of our Board are expensed over the requisite service period of each award, which is the vesting period, using the straight-line attribution method.

The fair value of PSU awards is calculated based on the closing price of our common stock on the date of grant. The actual stock-based compensation expense is dependent on the number of PSUs that are ultimately awarded, not the number of PSUs granted. As a result, we are required to estimate, based on our best judgment, the number of PSUs that will ultimately be awarded. In fiscal 2020, the cost of the estimated PSU awards was expensed pursuant to the 'graded' vesting concept whereby a higher amount of amortization expense is incurred in the early portion of the vesting period, as compared to the later part of the period. This is required in an attempt to separate the performance period of the award as compared to the retention period of the award.

With respect to the RSU award covering 2.7 million shares of our common stock granted to our CEO as part of the terms of the Amended CEO Agreement (the 'Award Shares'), this RSU award vests only in the event of a Qualifying Termination (see '- Employment Arrangements with Named Executive Officers - Employment Agreement with Mr. Kiani' on page 75 of this Proxy Statement for details). Accordingly, and in accordance with ASC Topic 718, we will only recognize compensation expense for this contingent stock award at the time of a change of control of the Company or when it is determined that the occurrence of a Qualifying Termination is 'probable.' Should this occur, in accordance with applicable accounting standards, the amount of compensation expense that will be recognized will be based upon the fair value of the RSU award on the date of grant. At the present time, we do not believe that an occurrence of a Qualifying Termination is 'probable' and as a result, no stock-based compensation expense has been recorded related to this RSU award.

While the Compensation Committee considers the expense impact under ASC Topic 718 as one of the factors in granting equity awards, it also considers the importance of aligning the interests of our executive officers with the interests of our stockholders, the retentive value of equity awards and other factors, and makes its decisions regarding equity awards based on its evaluation of such factors.

(1)Amounts set forth in the 'Stock Awards' and 'Option Awards' columns for 2018, 2019 and 2020 reflect the grant date fair value of stock and option awards granted in the year indicated, computed in accordance with ASC Topic 718. These amounts reflect certain assumptions with respect to the stock and option awards and do not necessarily correspond to the actual value that will be recognized by the NEOs. The actual value, if any, that may be realized from a stock award or an option award is contingent upon the satisfaction of the conditions to vesting in that award, and, in the case of option awards, upon the excess of the stock price over the exercise price, if any, on the date the option award is exercised. See Note 18 of the Notes to Financial Statements included in our Annual Report on Form 10-K for the fiscal year ended January 2, 2021 that was filed with the SEC on February 23, 2021 for a discussion of the grant date fair value of the stock awards and the assumptions made in determining the grant date fair value of the PSUs, RSUs and stock options granted in fiscal years 2018, 2019 and 2020. For PSUs, amounts reflect the target number of shares subject to the PSUs, assuming all performance goals and other requirements are met. As described below, the PSUs earned will range from 50% to 200% of target based on the achievement of performance goals, which vest in the form of shares of our common stock following the conclusion of the three-year performance period. The maximum potential value of the PSUs (assuming 200% of target, the maximum potential value of the award) granted to each of our NEOs was as follows: Mr. Kiani: $17,999,773, Mr. Young: $1,799,941, Mr. Muhsin: $3,599,883, Mr. Levy: $1,799,941 and Mr. McClenahan: $1,799,941

(2)All amounts for fiscal 2020, 2019, and 2018 were paid pursuant to our Executive Bonus Incentive Plan.

(3)Consists of $8,550 in retirement savings plan matching contributions, $1,718 related to the net incremental costs of certain lodging, meals and other travel-related expenses incurred by his family and household members accompanying him during certain business travel pursuant to Mr. Kiani's employment agreement (see '-Employment Arrangements with Named Executive Officers-Employment Agreement with Mr. Kiani' on page 75 of this Proxy Statement), and $683,413 related to certain incremental costs for security personnel and security services provided to Mr. Kiani and his family at his personal residence or other non-Masimo facilities that were not directly-related to Masimo business. During 2020, as a result of the COVID-19 pandemic, Mr. Kiani worked a substantial part of the year away from the corporate headquarters, which increased the cost of security related services incurred. We have established a security program for Mr. Kiani that provides physical and personal security services as they may, from time to time, be deemed necessary. This security program is not limited to providing security services only at business facilities or functions or during business-related travel and can include providing security services during certain non-business occasions, including at his primary residence and during personal travel. We do not consider any such security services to be personal benefits as the requirement for this occasional security is directly the result of Mr. Kiani's role as our CEO and as our CEO, his personal safety is vital to our continued success.

(4)Consists of $8,550 in retirement savings plan matching contributions, and $1,500 in employer HSA contributions.

(5)Consists of $8,550 in retirement savings plan matching contributions, $34,650 related to certain incremental costs for periodic security personnel and a $10,000 cash payment in recognition of 20 years of service to Masimo, which is generally available to all employees after such period of time.

(6)Consists of $8,550 in retirement savings plan matching contributions and $1,500 in employer HSA contributions.

(7)Consists of $8,550 in retirement savings plan matching contributions.

Pension Benefits-Nonqualified Defined Contribution and Other Nonqualified Deferred Compensation

No pension benefits were paid to any of our NEOs during fiscal 2020. We do not currently sponsor any non-qualified defined contribution plans or non-qualified deferred compensation plans.

_______________

(1)Represents possible payments under the Executive Bonus Incentive Plan based on the base salary in effect for each NEO as of March 12, 2020, the grant date of the award. The fiscal 2020 Executive Bonus Incentive Plan provided that amounts payable thereunder would be based on the base salary in effect for each NEO as of the end of fiscal 2020, and actual payouts were therefore based on base salaries as of the end of fiscal 2020.

(2)For fiscal 2020, the Compensation Committee selected fiscal 2022 Adjusted Product Revenue(1) and fiscal 2022 Adjusted Non-GAAP Operating Margin(2) as the performance measures for the target PSU award percentages, each weighted equally. If performance objectives are achieved, the PSUs will vest on the date of the approval by the Audit Committee of the audit of our financial statements for fiscal 2022 (or such later date determined by the Compensation Committee).

(3)This option vests over a five-year period, with 20% of the shares subject to the option vesting on each anniversary of the grant date.

(4)For PSUs, amounts reflect the fair value of the award as of the grant date assuming achievement of the 'target' performance achievement level. For stock options, amounts reflect the fair value per share as of the grant date of the award multiplied by the number of shares granted. Regardless of the value on the grant date, the actual value will depend on the market value of our common stock on a date in the future when an award vests or stock option is exercised. As described below, the PSUs earned will range from 50%-200% of target based on the achievement of performance goals, which vests in the form of shares of our common stock following the conclusion of the three-year performance period. The maximum potential value of the PSUs (assuming 200% of target, the maximum potential value of the award) granted to each of our NEOs was as follows: Mr. Kiani: $17,999,773, Mr. Young: $1,799,941, Mr. Muhsin: $3,599,883, Mr. Levy: $1,799,941 and Mr. McClenahan: $1,799,941.

EMPLOYMENT ARRANGEMENTS WITH NAMED EXECUTIVE OFFICERS

Employment Agreement with Mr. Kiani

In November 2015, we entered into the Amended and Restated Employment Agreement (the 'November 2015 Agreement') with Mr. Kiani, our CEO. Following extensive deliberations and discussions with Mr. Kiani, our compensation consultant and legal advisors, the Compensation Committee agreed to amend the November 2015 Agreement on July 27, 2017 (as amended, the 'Amended CEO Agreement'). The Amended CEO Agreement is intended to retain Mr. Kiani as our CEO who, based on his proven ability to launch and build successful companies and his knowledge and visibility within the medical device industry, could attract other very lucrative job opportunities. The initial employment period under the Amended CEO Agreement ran until December 31, 2017, subject thereafter to automatic one-year extensions unless either party provides a notice of non-renewal to the other at least one year prior to the scheduled expiration.

The Amended CEO Agreement provides that Mr. Kiani will continue to serve as our CEO and Chairman of the Board. The Amended CEO Agreement also provides the following material terms and conditions, as may be adjusted from time to time by our Board or the Compensation Committee:

•Eligibility to receive a base salary of $1,000,000 per year, which is subject to adjustment by our Board or the Compensation Committee, and was adjusted to $1,159,275 per year in July 2020.

•Eligibility to receive an annual bonus equal to 100% of his base salary in the event we attain certain performance criteria set by our Board or the Compensation Committee under our annual incentive plan for our executive officers. The bonus payable will not be above the payment level determined based on actual achievement of the applicable performance criteria. In addition, Mr. Kiani's annual bonus payable if all applicable performance criteria are achieved at maximum levels will not exceed 200% of his base salary.

•Under the Amended CEO Agreement, Mr. Kiani is eligible to receive equity awards with a value at least consistent with equity awards granted to comparable CEOs of comparable companies (taking into account revenues, market capitalization and industry). Following approval of our 2017 Equity Plan by our stockholders at the 2017 Annual Meeting, Mr. Kiani agreed that the only equity awards he may be awarded must be approved by the Compensation Committee under the 2017 Equity Plan, consisting of both PSU awards and time-based options to purchase shares of our common stock.

•Right to participate in or receive benefits under all of our employee benefits plans and to be eligible to participate in any pension plan, profit-sharing plan, savings plan, stock option plan, life insurance, health-and-accident plan or similar arrangements made available to members of our management.

•Reimbursement for all reasonable expenses incurred and paid by him in the course of the performance of his duties under the Amended CEO Agreement and reimbursement for all reasonable travel and lodging expenses for his family and household members in the event they accompany him during business travel, which includes travel and hospitality expenses for first class airplane travel and accommodations, including travel by private or chartered aircraft. To the extent inconsistent with the Amended CEO Agreement, Mr. Kiani is exempt from our travel and expense policy and our expense reimbursement policy.

In addition, Mr. Kiani is entitled to certain post-employment compensation arrangements. Under the Amended CEO Agreement, we may terminate Mr. Kiani's employment for 'cause' (as defined below), as a result of his disability under certain circumstances, or for any other reason. Similarly, Mr. Kiani may terminate his employment for 'Good Reason' (as defined below), for health reasons, or for any other reason upon six months written notice to us. Specifically:

•If Mr. Kiani's employment is terminated for cause, he is entitled to receive his full base salary through the date of termination.

•If Mr. Kiani's employment is terminated as a result of his death, his designee or estate is entitled to receive his full base salary through the date of termination and an additional amount equal to 50% of his base salary then in effect as of the date of his death for each of three consecutive years following his death, which will be paid in substantially equal monthly installments over the three-year period.

•If Mr. Kiani's employment is terminated as a result of his disability, he is entitled to receive his full base salary through the date of termination and an additional amount equal to 75% of his base salary then in effect for each of two consecutive years following the date of termination, which will be paid in substantially equal monthly installments over the two-year period.

•In the event (i) we terminate Mr. Kiani's employment other than for cause, death or disability, or (ii) Mr. Kiani terminates his employment with us for Good Reason (each, a 'Qualifying Termination'), Mr. Kiani will receive the following payments and benefits:

◦payment of an amount equal to his full base salary through the date of termination, if applicable, and an additional amount equal to twice the sum of his base salary then in effect and the average annual bonus paid to him over the prior three years, which will be paid in installments over two years pursuant to our normal payroll practices; and

◦all of his outstanding options and other equity awards will immediately vest.

Mr. Kiani may provide a notice of termination for Good Reason under the Amended CEO Agreement up to two years following the event giving rise to the Good Reason to terminate.

In addition, upon a Qualifying Termination, we will issue Mr. Kiani the Award Shares pursuant to the terms of an RSU award agreement between us and Mr. Kiani and pay him a cash amount equal to $35.0 million (the 'Cash Payment' and, together with the Award Shares, the 'Special Payment'). The Cash Payment will be paid to Mr. Kiani as consideration for his agreement to comply with certain non-competition and non-solicitation obligations under a restrictive covenant agreement by and between Masimo and Mr. Kiani, and will be subject to repayment to us if Mr. Kiani materially breaches any of such obligations.

Further, in the event of a 'change in control' of Masimo (as defined below) prior to a Qualifying Termination, on each of the first and second anniversaries of the change in control, 50% of the Award Shares and 50% of the Cash Payment will vest, subject in each case to Mr. Kiani's continuous employment through each such anniversary date. However, in the event of a Qualifying Termination or a termination of Mr. Kiani's employment due to death or disability prior to either of such anniversaries, any remaining unvested amount of the Cash Payment and all of the unvested Award Shares will vest and be paid in full. In addition, in the event of a change in control of Masimo prior to a Qualifying Termination, Mr. Kiani's stock options and any other equity awards will vest in accordance with their terms, but in no event later than in two equal installments on each of the first and second anniversaries of the change in control, subject in each case to Mr. Kiani's continuous employment through each such anniversary date.

Pursuant to the Amended CEO Agreement, if any payment or benefit received or to be received by Mr. Kiani would be subject to any excise tax imposed by Section 4999 of the Code, then the payments and benefits payable to Mr. Kiani will be reduced so that no portion of the payments or benefits payable to Mr. Kiani is subject to the excise tax, but only if the after-tax amount of such payments and benefits, as so reduced, is equal to or greater than the after-tax amount of such payments and benefits without such reduction.

The Amended CEO Agreement also provides that in the event of a change in control, we must fund a grantor trust with an amount equal to the aggregate of the cash severance payment to which he would be entitled and the Special Payment, payable to Mr. Kiani in the event of a Qualifying Termination. In the event Mr. Kiani's employment is not terminated on or prior to the fifth anniversary of the change in control in a manner entitling him to such payments, the amounts held in the trust will revert to Masimo.

In addition, if Mr. Kiani's employment under the Amended CEO Agreement is terminated for any reason other than cause, Mr. Kiani will be entitled to participate in all of our employee benefit plans and programs that he participated in as of the date of his termination of employment for the full term of the Amended CEO Agreement as long as his participation is possible under the general terms and provisions of the plans. If for any reason Mr. Kiani is not permitted to participate in any of our employee benefit plans or programs after the date of his termination of employment, he will be entitled to reimbursement of the amount paid by him to obtain similar coverage to that offered by our benefit plans and programs but only up to the amount we would otherwise have paid on behalf of him as an employee of Masimo under the Amended CEO Agreement as of the date of his termination.

For purposes of the Amended CEO Agreement:

•termination for 'cause' generally means his termination of employment as a result of his willful and continued failure to substantially perform his duties under the Amended CEO Agreement, his willful engaging in gross misconduct materially injurious to us or his willful violation of the confidentiality and trade secret protection provisions contained in a restrictive covenant agreement with us if the violation results in demonstrably material injury to us. Any termination for cause must be approved by at least 75% of the entire membership of our Board.

•termination for 'Good Reason' generally means a termination of his employment by Mr. Kiani subsequent to (A) a diminution in his responsibilities, duties and authority, including him ceasing to serve as CEO of the Company or him ceasing to serve as Chairman of the Board or the designation of any director other than him as the lead director of the Board, (B) any reduction in his rate of compensation or fringe benefits, (C) Masimo's failure to comply with certain obligations relating to his compensation or place of work, (D) the provision of a notice not to renew the Amended CEO Agreement by Masimo, or (E) (1) a change in control (as defined below) was triggered as a result of a change in more than one third of the directors on the Board during a rolling

twenty-four month period, or (2) following, or in connection with, a 'change in control' triggered as a result of an acquisition, (i) the highest level of parent entity holding, directly or indirectly, majority voting control of the Company after the 'change in control' (the 'Acquirer Parent') is not a publicly-traded company, (ii) he does not become the, or is removed from the position of, CEO and Chairman of the Board of the Acquirer Parent, with such position being on terms and conditions reasonably acceptable to him, provided that the terms and conditions of employment providing for total compensation with a value comparable to the total compensation paid to the chief executive officers of comparable companies shall be deemed to be reasonable, or (iii) any other director is designated the lead director of the board of directors of the Acquirer Parent; provided that, in the case of clauses (A), (B), (C) and (E) above, 'Good Reason' will not be deemed to exist unless certain notice and cure period conditions are met and his resignation for Good Reason is effective within thirty days after the expiration of the cure period.

•a 'change in control' generally means (i) the acquisition by any person or group of more than 35% of our outstanding voting stock, (ii) the acquisition of our assets that have a total fair market value of 40% or more of the total fair market value of all of our assets immediately before the acquisition by any person or group, or (iii) a change in more than one third of the directors on our Board during a rolling 24-month period. For purposes of determining whether a change in control has occurred, a director (other than a director whose initial assumption of office is in connection with an actual or threatened election contest, including but not limited to, a consent solicitation, relating to the election of directors of the Company) whose election by the Board or whose nomination for election by the stockholders of the Company was approved by a vote of at least a majority of the directors then in office either who were directors at the beginning of such period or whose election or nomination for election was previously so approved will be treated as a member of the Board at the beginning of the 24-month period.

Offer Letters with Other Named Executive Officers

Messrs. Young, Muhsin, Levy, and McClenahan each signed an offer letter before commencing their employment with us. The offer letters set forth each executive officer's position and title, initial base salary, health benefits, number of options to be initially granted and the vesting schedule of such options. Additionally, each offer letter states that the executive officer's employment is 'at-will' and may be terminated at any time by either the officer or us for any reason.

Employee Proprietary Agreements

Each of our NEOs, other than our CEO, has also entered into a standard form agreement with respect to proprietary information and inventions. Our CEO has also entered into an agreement with respect to proprietary information and inventions. Among other things, these agreements obligate each NEO to refrain from disclosing any of our proprietary information received during the course of his employment and, with some exceptions, to assign to us any inventions conceived or developed during the course of his employment.

2007 Severance Protection Plan

The 2007 Severance Protection Plan (the 'Severance Plan') provides the benefits set forth below to the executives who are eligible to participate in the Severance Plan and who have signed severance agreements with us (the 'SeveranceAgreements'). The Board has the discretion to amend or terminate the Severance Plan prospectively, subject to the limitation that, in the event of a change in control, no amendments may be made during the 36 months following the change in control without a participant's consent if it would adversely affect the participant's benefit. The Compensation Committee is the Severance Plan administrator.

Each of our NEOs, other than our CEO, is a participant in the Severance Plan on the terms set forth below. The following general description of the Severance Plan is qualified by the actual terms of the Severance Plan document and the individual Severance Agreements signed by the participants.

Conditions to Severance Benefits. To the extent set forth below, a participant can receive either basic severance benefits or change in control severance benefits, but not both. Generally, in order to receive a basic or change in control severance benefit, the following conditions must be met:

•the participant must execute, within 60 days of termination, a general release of claims (which becomes irrevocable within such 60-day period), a non-disparagement agreement, an intellectual property nondisclosure agreement, and a non-competition agreement that covers the period during which the participant is receiving severance benefits;

•a participant entitled to the basic benefit must not have received any change in control severance benefits under the Severance Plan or any severance benefits equal to, or better than, the basic severance benefits pursuant to another arrangement between the participant and us;

•a participant entitled to the change in control benefit must not have received any basic severance benefits under the Severance Plan or any severance benefits equal to, or better than, the change in control severance benefits pursuant to another arrangement between the participant and us; and

•the participant must waive any and all rights, benefits and privileges to severance benefits that he might otherwise be entitled to receive under any other oral or written plan, employment agreement, or arrangement with us.

Basic Severance Benefits. Each of our NEOs, other than our CEO and Messrs. Young and Levy(1), are eligible for these benefits. Basic severance benefits are payable if a participant is terminated without 'cause' (as defined below) and are the following:

•an amount equal to annual salary determined at the highest rate in effect during the one-year period immediately prior to the date of termination, paid in installments according to normal payroll practices over 12 months commencing within 60 days following the participant's termination;

•COBRA continuation coverage at Company expense during the 12 months following termination; and

•the right to purchase life insurance through the Company during the 12 month period following his termination.

However, if a participant commences new employment during the one-year period following termination, any income or benefits received from new employment will reduce (on a dollar-for-dollar basis) these basic severance benefits.

Change in Control Severance Benefits. Each of our NEOs, other than our CEO and Messrs. Young and Levy(1), are eligible for the change in control severance benefits described in this paragraph. The change in control severance benefits are payable upon a covered termination (which generally consists of a termination by the Company without cause or a termination by the executive for Good Reason upon or within a certain period after a change in control) and consist of the following:

•if the participant has a covered termination because his current job is not offered to him on the date of the change in control, the participant will receive (i) an amount equal to his annual salary determined at the highest rate in effect during the one-year period immediately prior to the date of the covered termination, plus the average annual bonus paid to him over the three-year period prior to the change in control, and (ii) life insurance for the 12-month period following his termination;

•if the participant has a covered termination for a reason not described in the preceding clause, instead of one times base salary, he will receive two times base salary;

•the participant will receive COBRA continuation coverage at Company expense during the 12-month period following his termination; and

____________

(1) Messrs. Young and Levy are not currently entitled to any Basic Severance Benefits under the Severance Plan. In addition, each of Messrs. Young and Levy's Change in Control Severance Benefits under the Severance Plan are currently limited to the acceleration of 50% of his respective unvested stock options and other equity-based awards upon a covered termination on or after a change in control.

•upon the change in control, 50% of the participant's unvested stock options and other equity-based awards shall be fully accelerated as of the change in control and 100% of the unvested stock options and other equity-based awards shall be fully accelerated upon the participant's termination under circumstances that entitle him to change in control severance benefits noted above.

Change in control severance amounts will be paid in a lump sum cash payment within 60 days following the participant's termination, provided that the participant has met all of the conditions for his change in control severance payment.

The Severance Plan administrator has the right to reduce any change in control severance benefits payable to an executive to avoid triggering any 'excess parachute payments' under Section 280G of the Code. In addition, the Severance Plan administrator may delay the payment or issuance of any severance or change in control severance benefits for up to six months as necessary to avoid the imposition of additional tax under Section 409A of the Code.

Under the Severance Plan:

•'cause' generally means the participant's: (i) refusal or failure to perform his duties with us or to comply in all respects with our policies or the policies of any affiliate of ours after notice of a deficiency and failure to cure the deficiency within three business days following notice from us, unless he has delivered a bona fide notice of termination for Good Reason to us, and the reason for the termination has not been cured by us within 30 days of receipt of notice; (ii) engagement in illegal or unethical conduct that could be injurious to us or our affiliates; (iii) commitment of one or more acts of dishonesty; (iv) failure to follow a lawful directive from our CEO; or (v) indictment for any felony, or any misdemeanor involving dishonesty or moral turpitude.

•'change in control' generally means: (i) a merger or consolidation or a sale of all or substantially all of our assets unless more than 50% of the voting securities of the surviving or acquiring entity are held by our stockholders as of immediately prior to the transaction; (ii) the approval by our stockholders of the sale of all or substantially all of our assets; or (iii) without the prior approval of our Board, the acquisition by any person or group of securities representing beneficial ownership of 50% or more of our outstanding voting securities.

•'Good Reason' generally means, provided that the executive has provided us with notice of one of the following events within 15 days after it occurs, and we fail to cure the event within 30 days after receiving notice from the executive: (i) any material reduction by us in the participant's annual salary; (ii) any requirement that the participant change his principal location of work to any location that is more than 40 miles from the address of our current principal executive offices; or (iii) any material change in the participant's responsibilities.

Voluntary Resignation. Excluding a resignation for Good Reason during the period commencing upon a change in control and ending on the 36-month anniversary of the change in control, each participant has agreed to provide us with six months advance notice of his resignation in the event he wishes to voluntarily resign from his employment at any time during which the Severance Plan and his Severance Agreement are effective.

Potential Payments Upon Termination or Change in Control

The tables below estimate the amounts payable to our NEOs in the event that a change in control, termination of employment or both occurred on January 2, 2021, the last business day of Masimo's fiscal year that ended January 2, 2021. The closing price of our common stock, as reported on the Nasdaq Global Select Market, was $268.38 per share on December 31, 2020, the last trading day of fiscal 2020. The following tables exclude certain benefits, such as accrued vacation, that are available to all employees generally. The actual amount of payments and benefits that would be provided can only be determined at the time of a change in control and/or the NEO's qualifying separation from Masimo.

PAY RATIO DISCLOSURE

As required by Section 953(b) of the Dodd-Frank Wall Street Reform and Consumer Protection Act, and Item 402(u) of Regulation S-K under the Exchange Act, we are providing the following information about the relationship of the annual total compensation of all employees of our company and the annual total compensation of our CEO, Mr. Kiani.

For 2020, our most recently completed fiscal year:

•the median of the annual total compensation of all employees of our Company (other than our CEO) was $102,348; and

•the annual total compensation of our CEO, Mr. Kiani, was $15,493,723.

Based on this information, for 2020 the ratio of the annual total compensation of our CEO to the median of the annual total compensation of all employees was 151 to 1. This ratio is a reasonable estimate calculated in a manner consistent with Item 402(u) of Regulation S-K.

As explained by the SEC when it adopted Item 402(u), the rule was designed to allow stockholders to better understand and assess our compensation practices and pay ratio disclosures rather than to facilitate a comparison of this information from one company to another. However, the pay ratio rules provide companies with flexibility to select the methodology and assumptions used to identify the median employee, calculate the median employee's compensation and estimate the pay ratio. As a result, our methodology may differ from those used by other companies, which likely will make it difficult to compare pay ratios with other companies, including those within our industry.

We identified our median employee for the 2020 pay ratio analysis using the methodology and the material assumptions, adjustments, and estimates described below.

•To identify our median employee, we selected total cash compensation, which we calculated as annual base pay (using a reasonable estimate of the hours worked during 2020 for hourly employees and actual salary paid for our remaining employees) and the actual annual cash incentive awards earned for fiscal 2020, as the compensation measure to be used to compare the compensation of our employees for the 12-month period from January 1, 2020 through December 31, 2020.

•As of October 31, 2020, our employee population consisted of approximately 1,843 individuals, with approximately 1,229 employees in the United States and approximately 614 employees outside the United States. In determining this population, we considered the employees of our subsidiaries and all of our worldwide employees other than our CEO, whether employed on a full-time, part-time, temporary or seasonal basis. We did not include any contractors or other non-employee workers in our employee population.

•We annualized base pay for any full-time and part-time employees who commenced work during 2020.

•Using this approach, we selected the individual at the median of our employee population. Our median employee was a Supervisor, Document Control, based in the United States.

For purposes of our 2020 pay ratio, we calculated annual total compensation for this individual using the same methodology we use for our named executive officers as set forth in our Summary Compensation Table. We determined that such individual's annual total compensation for the fiscal year ended January 2, 2021 was $102,348 (excluding any estimated retirement and health benefits).

During 2020, Mr. Kiani served as our CEO. We determined Mr. Kiani's annual total compensation for the fiscal year ended January 2, 2021 was $15,493,723, as reported in our 2020 Summary Compensation Table.

OWNERSHIP OF OUR STOCK

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

The following table sets forth information as of April 5, 2021, with respect to the beneficial ownership of shares of our common stock by:

•each person or group known to us to be the beneficial owner of more than five percent of our common stock;

•each of our directors;

•each of our named executive officers; and

•all of our current directors and executive officers as a group.

This table is based upon information supplied by officers, directors and principal stockholders and a review of Schedules 13D and 13G, if any, filed with the SEC. Other than as set forth below, we are not aware of any other beneficial owner of more than five percent of our common stock as of April 5, 2021. Except as indicated by the footnotes below, we believe, based on the information furnished to us, that the persons and entities named in the table below have sole voting and investment power with respect to all shares of common stock that they beneficially own, subject to applicable community property laws.

Applicable percentage ownership is based on 55,000,432 shares of common stock outstanding as of April 5, 2021, adjusted as required by rules promulgated by the SEC. These rules generally attribute beneficial ownership of securities to persons who possess sole or shared voting power or investment power with respect to those securities. In addition, the rules include shares of common stock issuable pursuant to equity awards that are either currently exercisable, or that will become exercisable or otherwise vest on or before June 4, 2021, which is 60 days after April 5, 2021. These shares are deemed to be outstanding and beneficially owned by the person holding those options for the purpose of computing the percentage ownership of that person, but they are not treated as outstanding for the purpose of computing the percentage ownership of any other person.

Unless otherwise noted below, the address of each beneficial owner listed in the table is c/o Masimo Corporation, 52 Discovery, Irvine, California 92618.

STOCK OWNERSHIP POLICY

We maintain a stock ownership policy for our executive officers to align their interests with the interests of our stockholders, as follows:

Stock Ownership Guidelines
l	Reflects a market value multiple of base salary
l	Reviewed annually by the Nominating, Compliance and Governance Committee

For purposes of our policy, an executive officer's base salary during any calendar year is deemed to be his or her base salary as of the close of business on December 31st of the immediately preceding year.

Further, for purposes of calculating ownership under our policy, the following equity in the Company is included, whether vested or unvested: (i) shares of our common stock held directly by the executive officer or in a trust for the benefit of the executive officer or his or her family; (ii) shares of our common stock held by the executive officer jointly with, or separately by, his or her spouse and/or children sharing the same household as him or her; (iii) shares of our common stock held by the executive officer through a profit sharing, savings or deferral plan; and (iv) restricted stock or phantom stock held by the executive officer. Shares of our common stock subject to outstanding and unexercised stock options and unearned performance share awards are not included in the calculation.

Under our policy, if an executive officer fails to meet or, in unique circumstances, fails to show sustained progress toward meeting his or her target ownership level, the Compensation Committee may reduce future LTI equity awards and/or make payments of future annual and/or long-term cash incentive payouts in the form of shares of our common stock and/or impose other penalties. The Compensation Committee also retains the discretion not to levy penalties for non-compliance.

Our executive officers are expected to reach their target ownership level by the later of (i) March 2017 (if he or she was an executive officer in January 2012, the date when the stock ownership policy was adopted); or (ii) March 1st of the sixth calendar year following the date he or she first becomes an executive officer (if he or she was not an executive officer in January 2012), and to hold at least such minimum value in shares of our common stock for so long as applicable. As of the date hereof, each of the NEOs to whom the stock ownership requirements was applicable is in compliance with the stock ownership policy.

NON-EMPLOYEE DIRECTOR STOCK OWNERSHIP POLICY

In February 2016, our Nominating, Compliance and Corporate Governance Committee adopted a stock ownership policy that is applicable to each of our non-employee directors. Our Nominating, Compliance and Corporate Governance Committee believes this policy is an important tool in aligning the interests of our non-employee directors with the long-term interests of our stockholders.

The policy requires that our non-employee directors hold shares of Masimo stock with a value equal to at least $250,000. For purposes of calculating ownership under this policy, the following sources are included, whether vested or unvested: (i) shares of our common stock held directly by the non-employee director or in a trust for the benefit of the non-employee director or his family; (ii) shares of our common stock held by the non-employee director jointly with, or separately by, the non-employee director's spouse and/or children sharing the same household as the non-employee director; (iii) shares of our common stock held by the non-employee director through a profit sharing, savings or deferral plan; and (iv) restricted stock or phantom stock held by the non-employee director. Stock options, unvested RSU awards and unearned PSU awards are not included in the calculation.

To give our non-employee directors time to comply with our stock ownership policy, our Nominating, Compliance and Corporate Governance Committee determined that our non-employee directors have until the later of March 1, 2021 or the five-year anniversary of their appointment as a director to comply with these guidelines. As of March 1, 2021, all of Masimo's non-employee directors were in compliance with our stock ownership policy.

PROPOSALS TO BE VOTED ON

PROPOSAL:	TO ELECT A CLASS II DIRECTOR AS NAMED IN OUR PROXY STATEMENT
1

Overview

The term of office for Class II Directors expires in 2021. Based on the recommendation of our Nominating, Compliance and Corporate Governance Committee, the Board has nominated Mr. Joe Kiani for election to the Board as a Class II Director. If elected at the Annual Meeting, Mr. Joe Kiani would serve until the 2024 Annual Meeting of Stockholders and until his successor is elected and qualified or, if sooner, until his death, resignation or removal.

Our Bylaws provide for a majority voting standard for uncontested elections of directors. This standard states that in uncontested director elections, a director nominee will be elected only if the number of votes cast 'For' the nominee exceeds the number of votes cast 'Against' the nominee. Under our Bylaws, in the event an incumbent nominee does not receive a majority of the votes cast for the incumbent director's re-election, the incumbent director is required to promptly tender his resignation to the Board. Our Nominating, Compliance and Corporate Governance Committee will then make a recommendation to the full Board as to whether to accept or reject the tendered resignation, or whether other action should be taken. Our Board will then decide whether to accept or reject the resignation, taking into account the Nominating, Compliance and Corporate Governance Committee's recommendation. The determination of our Board and the rationale behind the decision will be publicly disclosed (by a press release, a filing with the SEC or other broadly disseminated means of communication) within 90 days from the date of the certification of the election results of our Annual Meeting. If the incumbent director's resignation is not accepted by our Board, the director will continue to serve until his successor is duly elected, or his earlier resignation or removal. If a director's resignation is accepted by our Board, then our Board may fill any resulting vacancy or decrease the size of the Board.

Nominee

The Nominating, Compliance and Corporate Governance Committee recommends, and the Board nominated, the following individual for election for a three-year (Class II) term expiring at the 2024 Annual Meeting of Stockholders:

Nominee	Term in Office
Joe Kiani	Class II - Continuing in Office Until the 2024 Annual Meeting of the Stockholders

The nominee has agreed to serve as a director if elected. We have no reason to believe that the nominee will be unable to serve. The section titled 'Board of Directors' beginning on page 19 of this Proxy Statement contains the nominee's biography.

þ	THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR THE ELECTION OF THE NOMINEE NAMED ABOVE.

The following directors will remain in office until the date specified below:

Current Directors	Class and Remaining Term in Office
Adam Mikkelson	Class III - Continuing in Office Until the 2022 Annual Meeting of the Stockholders
Craig Reynolds	Class III - Continuing in Office Until the 2022 Annual Meeting of the Stockholders
Julie A. Shimer, Ph.D.	Class I - Continuing in Office Until the 2023 Annual Meeting of the Stockholders
H Michael Cohen	Class I - Continuing in Office Until the 2023 Annual Meeting of the Stockholders

PROPOSAL:	TO RATIFY THE SELECTION OF GRANT THORNTON LLP AS OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR THE FISCAL YEAR ENDING JANUARY 1, 2022
2

The Audit Committee of our Board has selected Grant Thornton LLP ('Grant Thornton') as our independent registered public accounting firm for the fiscal year ending January 1, 2022, and has further directed that management submit the selection of our independent registered public accounting firm for ratification by the stockholders at the Annual Meeting.

Grant Thornton was appointed as our independent registered public accounting firm in July 2006 and has reported on our consolidated financial statements for years 2005 through 2020. The decision to select Grant Thornton as our independent registered public accounting firm for fiscal year 2021 (ending January 1, 2022) was recommended by our Audit Committee and approved by our Board.

Representatives of Grant Thornton are expected to be present at the Annual Meeting. The representatives of Grant Thornton will be able to make a statement at the meeting if they wish and will be available to respond to appropriate questions.

Neither our Bylaws nor other governing documents or law require that our stockholders ratify the selection of Grant Thornton as our independent registered public accounting firm. However, the Audit Committee is submitting the selection of Grant Thornton to the stockholders for ratification as a matter of good corporate practice. If our stockholders fail to ratify the selection, the Audit Committee will reconsider whether or not to retain that firm. Even if the selection is ratified, the Audit Committee in its discretion may direct the appointment of different independent registered public accounting firms at any time during the year if it determines that such a change would be in the best interests of Masimo and our stockholders.

Although our stockholders are not required to ratify the selection of Grant Thornton as our independent registered public accounting firm, because we have submitted the ratification of our registered public accounting firm for approval by stockholders, the affirmative vote of the holders of a majority of the shares present or represented by proxy and voting at the Annual Meeting (which shares voting affirmatively also constitute at least a majority of the required quorum) will be required to ratify the selection of Grant Thornton as our independent registered public accounting firm for the fiscal year ending January 1, 2022.

þ	THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR THE RATIFICATION OF THE SELECTION OF GRANT THORNTON LLP AS OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR THE FISCAL YEAR ENDING JANUARY 1, 2022.

PROPOSAL:	TO PROVIDE AN ADVISORY VOTE TO APPROVE THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS
3

Our Board of Directors requests that our stockholders approve the compensation of our Named Executive Officers pursuant to Section 14A of the Exchange Act, as described in this Proxy Statement in the section titled 'Compensation Discussion and Analysis' beginning on page 43 of this Proxy Statement, and the compensation tables beginning on page 69 of this Proxy Statement, and any related narrative discussion contained throughout this Proxy Statement.This vote is advisory and not binding on the Company, but the Board of Directors values the opinions of our stockholders and will consider the outcome of the vote in determining our executive compensation programs.

'Say-on-Pay Vote'

Our Board maintains a pay for performance philosophy that forms the foundation for all of the Compensation Committee's decisions regarding executive compensation. In addition, our compensation programs are designed to facilitate strong corporate governance, foster collaboration and support our short and long-term strategy.

The Compensation Discussion and Analysis portion of this Proxy Statement contains a detailed description of our executive compensation philosophy and programs, including the compensation decisions the Compensation Committee has made under those programs and the factors considered in making those decisions. Our stockholders have affirmed their support of our programs in our outreach discussions and in the last several year's Say on Pay results. We believe that we have created a compensation program deserving of stockholder support.

In light of the above, we believe that the compensation of our named executive officers for fiscal 2020 was appropriate and reasonable, as well as reflective of our performance for the year. Accordingly, the following resolution will be submitted for a stockholder vote at the Annual Meeting:

'RESOLVED, that the stockholders of Masimo Corporation approve, on an advisory basis, our named executive officer compensation for fiscal 2020, as disclosed pursuant to Item 402 of Regulation S-K, including the Compensation Discussion and Analysis, compensation tables and related narrative discussion, in this Proxy Statement.'

This stockholder vote on named executive officer compensation is merely advisory and will not be binding upon us, our Board or our Compensation Committee. The outcome of the vote will not require us, our Board or our Compensation Committee to take any action or overrule any decision by the Company, our Board or the Compensation Committee. However, our Board and Compensation Committee value the opinions of our stockholders and will consider the outcome of the vote when making future executive compensation decisions.

þ	THE BOARD OF DIRECTORS RECOMMENDS A VOTE TO APPROVE THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS AS DESCRIBED IN THIS PROXY STATEMENT.

RELATED PERSON TRANSACTIONS POLICY AND PROCEDURES

We adopted a written Related Person Transactions Policy that sets forth our policies and procedures regarding the identification, review, consideration and approval or ratification of transactions with related persons. For purposes of our policy only, a 'related person transaction' is a transaction, arrangement or relationship (or any series of similar transactions, arrangements or relationships) in which we (including any of our subsidiaries) and any 'related person' were, are or will be participants involving an amount that exceeds $120,000. For purposes of the policy, a related person is:

•any person who is or was a director or executive of ours since the beginning of our immediately preceding fiscal year or an immediate family member of, or person sharing a household with, any of the foregoing individuals;

•any person known by us to be the beneficial owner of more than five percent of any class of our outstanding voting securities or, if the beneficial owner is an individual, an immediate family member of, or person sharing a household with, any of the foregoing individuals; and

•any firm, corporation or other entity in which any of the foregoing individuals is employed or is a general partner or principal or in a similar position, or in which any of the foregoing individuals has a five percent or greater beneficial interest.

Under the policy, prior to entering into a related person transaction, our legal department must present information regarding the proposed related person transaction to our Nominating, Compliance and Corporate Governance Committee for approval at its next regularly scheduled meeting (or, where our legal department, in consultation with our CEO or Chief Financial Officer, determines that it is not practicable to or desirable to wait until the next meeting of the Nominating, Compliance and Corporate Governance Committee, to the Chairperson of our Nominating, Compliance and Corporate Governance Committee, who is authorized under the policy to act on behalf of the Nominating, Compliance and Corporate Governance Committee with respect to matters covered by the policy between meetings of the Nominating, Compliance and Corporate Governance Committee).

To identify proposed related person transactions in advance, our legal department relies on information supplied by our directors, executive officers or business unit or function/department leader responsible for the proposed related person transaction. In considering related person transactions, the Nominating, Compliance and Corporate Governance Committee (or the Chairperson of the Nominating, Compliance and Corporate Governance Committee) takes into account all relevant facts and circumstances related to the proposed transaction. In the event a member of the Nominating, Compliance and Corporate Governance Committee, or any immediate family member or affiliate of a member of the Nominating, Compliance and Corporate Governance Committee is the related person, such member of the Nominating, Compliance and Corporate Governance Committee is prohibited from participating in any review, consideration or approval of the related person transaction. The policy requires that the Nominating, Compliance and Corporate Governance Committee will only approve a related person transaction if it determines that the transaction is in, or is not inconsistent with, our best interests and the best interests of our stockholders.

Table of Contents	ADDITIONAL INFORMATION

Under the policy, the following related person transactions are deemed to be pre-approved by the Nominating, Compliance and Corporate Governance Committee regardless of the amount involved:

•employment and compensation of our executive officers, subject to certain exceptions;

•compensation of our directors, subject to certain exceptions;

•certain transactions between us and an unrelated third party entity in which the related person's only relationship with the third party is as an employee (other than an executive officer), director or beneficial owner of less than 10% of the other entity's shares, subject to certain limitations;

•certain contributions to the Masimo Foundation and certain other charitable contributions; and

•transactions in which all of our stockholders receive the same benefit on a pro rata basis.

The policy also permits our Nominating, Compliance and Corporate Governance Committee to ratify, amend, rescind or terminate any related person transaction that is not pre-approved in accordance with the terms above.

TRANSACTIONS WITH RELATED PERSONS

The following is a description of transactions or series of transactions since January 2, 2021, or any currently proposed transaction, to which we were or are to be a participant in which the amount involved in the transaction or series of transactions exceeds $120,000, and in which any of our directors, executive officers or persons who we know held more than five percent of any class of our capital stock, including their immediate family members, had or will have a direct or indirect material interest, other than compensation arrangements that are described under 'Executive Compensation-Employment Contract and Severance Arrangements' above.

CERCACOR LABORATORIES, INC.

Cercacor is an independent entity spun off from us to our stockholders in 1998. Joe Kiani, our Chairman and CEO, is also the Chairman and CEO of Cercacor. Mr. Kiani receives a separate salary and equity compensation from Cercacor in his capacity as an employee of Cercacor.

We are a party to the Cross-Licensing Agreement with Cercacor, which governs each party's rights to certain of the intellectual property held by the two companies. To date, we have developed and commercially released devices that measure carbon monoxide, methemoglobin and hemoglobin using licensed rainbow® technology. Pursuant to the Cross-Licensing Agreement, we are currently subject to certain specific minimum royalty payment obligations of $5.0 million per year. Actual aggregate royalty payment liabilities payable to Cercacor were approximately $13.3 million for fiscal 2020.

We have also entered into the Services Agreement with Cercacor, which governs certain general and administrative services we provide to Cercacor. Pursuant to the Services Agreement, Cercacor paid us approximately $0.3 million for general and administrative services related to fiscal 2020.

In December 2019, we entered into a new lease agreement with Cercacor for approximately 34,000 square feet of office, research and development space at one of our owned facilities in Irvine, California ('Cercacor Lease'). The Cercacor Lease expires on December 31, 2024. In March 2016, we entered into a sublease with Cercacor, pursuant to which we subleased approximately 16,830 square feet of excess office and laboratory space located at 40 Parker, Irvine, California to Cercacor ('Cercacor Sublease'). The Cercacor Sublease began on May 1, 2016 and expired on December 15, 2019. We recognized approximately $1.1 million of combined lease and sublease income pursuant to the Cercacor Lease and Cercacor Sublease during fiscal 2020.

Prior to our initial public offering in August 2007, our stockholders owned approximately 99.9% of the outstanding capital stock of Cercacor, and we believe that as of April 5, 2021, a number of stockholders of Cercacor continued to own shares of our common stock. Mr. Kiani is the only stockholder of Cercacor who owns 5% or more of Masimo's outstanding voting stock.

In addition, for the year ended January 2, 2021, we made various in-kind contributions to the Masimo Foundation, mainly in the form of donated administrative services.

PATIENT SAFETY MOVEMENT FOUNDATION

The Patient Safety Movement Foundation ('PSMF') is a non-profit organization which was founded in 2013 to work with hospitals, medical technology companies and patient advocates to unite the healthcare ecosystem and eliminate the more than 200,000 U.S. preventable hospital deaths that occur every year.

The organization holding your account is considered the stockholder of record for purposes of voting at the Annual Meeting. As a beneficial owner, you have the right to direct your broker, bank or other agent regarding how to vote the shares in your account. Certain of these institutions offer the ability to direct your agent how to vote through the internet or by telephone. You are also invited to attend the Annual Meeting.

You should sign the proxy card and return it in the enclosed envelope, or you may submit your proxy over the internet or by telephone by following the instructions on the enclosed proxy card. Fidelity will vote your Savings Plan shares as of the record date in the manner directed in the last timely voting instructions that are received from you. If voting instructions are not received from you by 11:00 p.m. Pacific Daylight Time on May 24, 2021, Fidelity will vote your Savings Plan shares as of the record date in the same manner, proportionally, as it votes the other shares of common stock for which proper and timely voting instructions of other Savings Plan participants have been received by Fidelity. You may change or revoke previously given voting instructions in any of the ways described under the question 'Can I change my vote after submitting my proxy?'; however, your revocation or changed voting instructions must be received no later than 11:00 p.m. Pacific Time on May 24, 2021 or else we will not be able to timely notify Fidelity of your revoked or changed voting instructions.

9. How many votes do I have?

On each matter to be voted upon, holders of common stock will have one vote for each share of common stock they owned as of the close of business on April 5, 2021, the record date for the Annual Meeting.

10. Will my vote be kept confidential?

Proxies, ballots and voting tabulations are handled on a confidential basis to protect your voting privacy. This information will not be disclosed, except as required by law.

11. Who is paying for this proxy solicitation?

We will bear the cost of soliciting proxies for the Annual Meeting. We will ask banks, brokerage houses, fiduciaries and custodians holding shares of Masimo common stock in their names for others to send proxy materials to and obtain proxies from the beneficial owners of such shares, and we will reimburse them for their reasonable expenses in doing so. We and our directors, officers and regular employees may solicit proxies by mail, personally, by telephone or by other appropriate means. No additional compensation will be paid to directors, officers or other regular employees for such services.

12. Why did I receive a Notice of Internet Availability of Proxy Materials (the 'Notice') instead of a full set of proxy materials

In accordance with the rules of the SEC, we have elected to furnish our proxy materials, including this Proxy Statement and our annual report, primarily via the Internet. Stockholders may request to receive proxy materials in printed form by mail or electronically by e-mail by following the instructions contained in the Notice. We encourage stockholders to take advantage of the availability of our proxy materials on the Internet to help reduce the environmental impact of our annual meetings of stockholders.

13. What does it mean if I receive more than one Notice?

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

14. Can I change my vote after submitting my proxy?

Yes. You can revoke your proxy at any time before the final vote at the Annual Meeting. If you are a stockholder of record, you may revoke your proxy in any one of four ways:

•You may submit another properly completed and executed proxy card with a later date;

•You may submit a new proxy through the internet or by telephone (1-800-652-VOTE) (your latest internet or telephone instructions submitted prior to the deadline will be followed);

•You may send a written notice that you are revoking your proxy to our Corporate Secretary, c/o Masimo Corporation, 52 Discovery, Irvine, California 92618, by the deadline; or

•You may attend the Annual Meeting and vote virtually. However, simply attending the Annual Meeting will not, by itself, revoke your proxy.

If you are a beneficial owner of shares registered in the name of your broker, bank or other agent, follow the voting instructions from that organization included with these proxy materials, or contact that organization to determine how you may revoke your proxy.

Votes will be counted by the inspector of election appointed for the Annual Meeting.

15. How are my shares voted if I give no specific instruction?

We must vote your shares as you have instructed. If there is a matter on which a stockholder of record has given no specific instruction but has authorized us generally to vote the shares, they will be voted as follows:

•'For' the election of the Class II director nominee;

•'For' the ratification of the selection of Grant Thornton LLP as our independent registered public accounting firm for the fiscal year ending January 1, 2022; and

•'For' the approval of our named executive officer compensation.

This authorization would exist, for example, if a stockholder of record merely signs, dates and returns the proxy card but does not indicate how its shares are to be voted on one or more proposals. If other matters properly come before the Annual Meeting and you do not provide specific voting instructions, your shares will be voted at the discretion of the proxies.

If your shares are held in street name, see 'What is a broker non-vote?' below regarding the ability of brokers, banks and other such holders of record to vote the uninstructed shares of their customers or other beneficial owners in their discretion and regarding broker non-votes.

16. What is a broker non-vote?

Under rules that govern brokers, banks and others who have record ownership of company stock held in brokerage accounts for their clients who beneficially own the shares, these brokers, banks and other such holders who do not receive voting instructions from their clients have the discretion to vote uninstructed shares on certain matters ('discretionary matters') but do not have discretion to vote uninstructed shares as to certain other matters ('non-discretionary matters'). Only the ratification of auditors is considered a discretionary matter at the Annual Meeting under these rules. A broker may return a proxy card on behalf of a beneficial owner from whom the broker has not received voting instructions that casts a vote with regard to discretionary matters but expressly states that the broker is not voting as to non-discretionary matters. The broker's inability to vote with respect to the non-discretionary matters for which the broker has not received voting instructions from the beneficial owner is referred to as a 'broker non-vote.'

17. What are the voting requirements that apply to the proposals discussed in this Proxy Statement?
Proposals	Vote Required		Discretionary Voting Allowed?
1. Election of Director	Majority Cast		No
2. Ratification of Auditors	Majority Cast	Yes
3. Advisory Vote to Approve the Compensation of our Named Executive Officers	Majority Cast	No

A 'majority cast', with regard to the election of a director, means the number of votes cast 'for' a nominee election must exceed the number of votes cast 'against' such nominee election. A 'majority cast', with regard to the ratification of auditors and the advisory vote to approve our named executive compensation, means the number of votes cast 'for' the proposal must exceed the number of votes cast 'against' such proposal.

'Discretionary voting' occurs when a broker, bank or other holder of record does not receive voting instructions from the beneficial owner and votes those shares at its discretion on any proposal as to which rules permit such broker, bank or other holder of record to vote. As noted above, when brokers, banks and other holders of record are not permitted under the rules to vote the beneficial owner's shares, the affected shares are referred to as 'broker non-votes.'

Table of Contents	ADDITIONAL INFORMATION

Although the vote on Proposal No. 3 is advisory and non-binding, as provided by law, our Board will review the results of the vote and, consistent with our record of stockholder engagement, will consider the results in making future decisions concerning executive compensation.

18. What is the effect of abstentions and broker non-votes?

Abstentions: Under Delaware law (under which Masimo is incorporated), abstentions are counted as shares present and entitled to vote at the Annual Meeting, but they are not counted as shares cast. Therefore, abstentions will have no effect on Proposal No. 1-Election of Director; Proposal No. 2-Ratification of Auditors; Proposal No. 3-Advisory Vote to Approve the Compensation of our Named Executive Officers.

Broker Non-Votes: As a result of a change in rules related to discretionary voting and broker non-votes, brokers, banks and other such record holders are no longer permitted to vote the uninstructed shares of their customers on a discretionary basis in the election of directors or on named executive officer compensation matters. Because broker non-votes are not considered under Delaware law to be entitled to vote at the Annual Meeting, they will have no effect on the outcome of the vote on: Proposal No. 1-Election of Director, Proposal No. 3-Advisory Vote to Approve the Compensation of our Named Executive Officers.

As a result, if you hold your shares in street name and you do not instruct your broker, bank or other such holder how to vote your shares in the election of directors or the advisory vote related to the approval of our executive compensation program, no votes will be cast on your behalf on these proposals. Therefore, it is critical that you indicate your vote on these proposals if you want your vote to be counted. Proposal No. 2, the proposal to ratify the selection of Grant Thornton LLP as our independent registered public accounting firm for the fiscal year ending January 1, 2022, should be considered a discretionary matter. Therefore, your broker, bank or other such holder will be able to vote on this proposal even if it does not receive instructions from you, so long as it holds your shares in its name.

19. What happens if an incumbent director nominee does not receive a majority of the votes cast for his re-election?
