LETTER TO SHAREHOLDERS

	David A. Jones Pentair Chairman of the Board John L. Stauch Pentair President and Chief Executive Officer			You are cordially invited to attend the Annual General Meeting of Shareholders of Pentair plc on Tuesday, May 17, 2022, at 8:00 a.m. local time (BST). The Annual General Meeting of Shareholders will be held at Claridge’s, Brook Street, Mayfair, London, W1K 4HR, United Kingdom. The enclosed notice of annual general meeting and proxy statement describe the items of business that we will conduct at the meeting and provide you with important information about Pentair plc, including our practices in the areas of corporate governance and executive compensation. We strongly encourage you to read these materials and then to vote your shares. Our Board successfully navigated the continued challenges and opportunities of 2021 We exited 2021 feeling very grateful for the tireless efforts of all of our employees to help Pentair deliver for our customers and create value for shareholders in light of another year of unique challenges and opportunities. We are proud of how our employees once again rose to meet the challenges of the year including addressing significant inflation and global supply chain disruptions and remained agile and accountable throughout 2021. Our 2021 results exceeded our expectations and we are looking forward to continued momentum and success in 2022. In 2021, we continued investing in our brand, our digital capabilities, and our innovation around smart and sustainable solutions. Our Pool business benefited from a large installed base, movement to more autonomous and more energy efficient pools and favorable population migration trends. Our Water Treatment business has built momentum on the Residential side with smarter, connected solutions, while our more profitable Commercial business has recovered nicely despite restaurant traffic still not back to 2019 levels. Finally, our Industrial businesses exited 2021 with continued growth in orders and backlog, particularly in our Food and Beverage and Sustainable Gas businesses. Overall, we believe we are well positioned entering the new year.
	Our Board is overseeing our initiatives and progress in advancing our journey toward delivering a more sustainable company At the beginning of 2021, we announced advances in our commitment to further environmental, social and governance (ESG) stewardship. Our efforts led to the release of our annual Corporate Responsibility Report in June 2021, which highlighted our initiatives to be a leading socially responsible company. At the same time, we announced social responsibility strategic targets in the areas of carbon footprint reduction, water reduction, product design for sustainability, responsible supply chain and inclusion and diversity. We also signed the CEO Action Pledge for Diversity and InclusionTM, committing to a specific set of plans to cultivate an inclusive environment. We are striving to make the world better through our products and solutions, inspiring people to move, improve and enjoy life’s essential resources for happier, healthier lives. Our Board continues to add expertise and enhance its oversight of key governance areas During 2021, our Board reviewed the allocation of risk oversight among the Board and its committees and amended the charter of our Audit and Finance Committee to specifically acknowledge its oversight of risk exposures related to information security, cyber security and data protection. Effective December 1, 2021, Melissa Barra joined our Board as an independent director, bringing a strong background in customer experience, services and strategy in business to consumer environments, as well as experience in digital transformation and information technology. With Melissa joining the Board, we have further expanded the diversity of perspectives and experiences on our Board that continue to help us succeed in this dynamic environment. We remain committed to ensuring strong governance at Pentair, which is demonstrated through practices such as our independent board leadership, annual election of directors and providing shareholders with proxy access rights. On behalf of the entire Board, we thank you for your confidence in us. We value your investment, your input and your support.

PROPOSAL 1

				RE-ELECT DIRECTOR NOMINEES
							The Board recommends a vote FOR each Director nominee

Our Board currently has ten members. The size of our Board is limited to no fewer than seven and no more than eleven members, and our Board believes that any size in this range is appropriate. On the recommendation of the Governance Committee, our Board has nominated the ten director nominees named in the resolutions below, all of whom are current directors for re-election for a one-year term expiring on completion of the 2023 Annual General Meeting. If any of the director nominees should become unable to accept election, your proxy or proxies may vote for other persons selected by the Board. Management has no reason to believe that any of the director nominees named below will be unable to serve his or her full term if elected.

Biographies of the director nominees follow. These biographies include for each director his or her age (as of the date of the filing of this Proxy Statement); his or her business experience; his or her directorships in public companies and other organizations within the past five years; and a discussion of the specific experience, qualifications, attributes or skills that led to the conclusion that each should serve as a director.

Melissa Barra is standing for election by our shareholders for the first time. In September 2021, Ms. Barra was appointed by our Board to serve as a director effective December 1, 2021. Ms. Barra was initially identified as a potential candidate for our Board by an independent search firm who assisted the Governance Committee in identifying and evaluating potential candidates.

The text of the resolutions with respect to Proposal 1 is as follows:

“IT IS RESOLVED, by separate resolutions to re-elect the following ten director nominees for a term expiring on completion of the 2023 Annual General Meeting:

	(i) Mona Abutaleb Stephenson			(vi) David A. Jones
	(ii) Melissa Barra			(vii) Gregory E. Knight

TABLE OF CONTENTS

PROPOSAL 1

DIRECTOR INDEPENDENCE

The Board, based on the recommendation of the Governance Committee, determines the independence of each director based upon the New York Stock Exchange (“NYSE”) listing standards and the categorical standards of independence included in our Corporate Governance Principles. Based on these standards, the Board has affirmatively determined that all of our non-employee directors (i.e., Mses. Abutaleb, Barra, Bryan, and Williamson and Messrs. Glenn, Harris, Jones, Knight, and Speetzen) are independent and have no material relationship with us (including our directors and officers) that would interfere with their exercise of independent judgment. Mr. Stauch, our President and Chief Executive Officer, is the only director who is not independent.

In determining independence, our Board and Governance Committee consider circumstances where a director serves as an employee of another company that is a customer or supplier. The Board and Governance Committee have reviewed each of these relationships,

which are set forth below. In every case, the relationship involves sales to or purchases from the other company that, for each of 2019, 2020, and 2021, were (a) less than the greater of $1 million or 2% of that organization’s consolidated gross revenues during each of 2019, 2020, and 2021; and (b) not of an amount or nature that impeded the director’s exercise of independent judgment.

	Director			Relationship(s) Considered
	Ms. Bryan			Chief Financial Officer, Insight Enterprises, Inc.
	Mr. Jones			Senior Advisor, Oak Hill Capital Partners
	Mr. Knight			Executive Vice President, Customer Transformation and Business Services of CenterPoint Energy, Inc.
	Mr. Speetzen			Chief Executive Officer, Polaris Inc.

DIRECTOR QUALIFICATIONS; DIVERSITY AND TENURE

The Governance Committee and the Board recognize that the Board’s contributions and effectiveness depend on the character and abilities of each director individually as well as on their collective strengths. Accordingly, the Governance Committee and the Board evaluate candidates based on several criteria. Directors are chosen with a view to bringing to the Board a diversity of skills, qualifications, experiences, perspectives and backgrounds. In this regard, the Governance Committee and the Board consider diversity of age, gender, race, ethnicity and other characteristics. The Governance Committee and the Board seek to establish a core of strategic and business advisers with financial and management expertise, and also consider candidates with substantial experience outside the business community, such as in the public, academic or scientific communities. In addition, the Governance Committee and the Board consider the tenure of incumbent directors, with the goal of having a mix of shorter-tenured directors who provide fresh perspectives and longer-tenured directors who provide institutional knowledge regarding our company and our business.

When considering candidates for election as directors, the Governance Committee and the Board are guided by the following principles, found in our Corporate Governance Principles:

▶

at least a majority of the Board must consist of independent directors;

▶

each director should be an individual of the highest character and integrity and have an inquiring mind, vision and the ability to work well with others;

▶

each director should be free of any conflict of interest that would violate any applicable law or regulation or interfere with the proper performance of his or her responsibilities as a director;

▶

each director should possess substantial and significant experience that could be important to us in the performance of his or her duties;

▶

each director should have sufficient time available to devote to our affairs; and

▶

each director should have the capacity and desire to represent the balanced, best interests of the shareholders as a whole and not primarily the interests of a special interest group or constituency and be committed to enhancing long-term shareholder value.

The Governance Committee in the first instance is charged with observing these policies, and strives in reviewing each candidate to assess the fit of his or her qualifications with the needs of the Board and our company at that time, given the then current mix of directors’ attributes.

We are focused on further integrating our environmental, social, and governance (ESG) goals throughout our business by creating broad accountability for our social responsibility strategy and creating shared commitments and targets. In 2021, Pentair announced social responsibility targets reflecting ESG topics of importance to our shareholders, customers, suppliers, employees, and communities.

Environmental

We are focused on reducing our impact on climate change by reducing greenhouse gas emissions while increasing energy and water use efficiency measures throughout our operations. We also seek to continue reducing waste from operations; increase reuse and recycling; support the use of sustainable, renewable natural resources; and design products that facilitate environmental sustainability.

Social

We are focused on enhancing our efforts to engage our suppliers, customers and employees by augmenting our supplier code of conduct. We are also focused on continuing our employee engagement efforts, and executing on our inclusion and diversity strategies and initiatives. We also remain committed to providing a safe workplace for all our employees.

Governance

Our Board of Directors provides ESG oversight by periodically reviewing our ESG strategy, including ESG targets, communications, and risks. In addition, the Governance Committee oversees ESG strategy and risks, including business sustainability risks.

We have published an annual corporate responsibility report that has reported on ESG and our accomplishments. In addition, in 2021 we established a formal social responsibility program to further advance our social responsibility goals.

Karla Robertson, our EVP, General Counsel, and Secretary, serves in the additional role of Chief Social Responsibility Officer. She leads Pentair’s social responsibility program and provides regular ESG updates to our Board of Directors and its Governance Committee.

As part of the social responsibility program, we have a team of professionals dedicated to executing our ESG strategy, and managing sustainability policies, initiatives, and public reporting. Cross functional leaders work with our dedicated social responsibility team of professionals to integrate ESG into their functions and businesses and drive the ESG culture.

Through our business risk review process we assess climate risks across our portfolio. Our risk assessments provide us with insights for determining applicable mitigation measures so that we can take appropriate preventative steps to

THE BOARD’S ROLE AND RESPONSIBILITIES

Risk Oversight

The Board is responsible for general oversight of our risk management. The Board focuses on the most significant and material risks facing us and helps to ensure that management develops and implements controls and appropriate risk mitigation strategies.

At the direction of the Board, we have instituted an enterprise-wide risk management process that identifies potential exposure to risks that arise in the course of our business. The Board has determined that the Board as a whole, and not a separate committee, will oversee our enterprise risk management process. Each of our Board Committees has historically focused and continues to focus on specific risks within its respective

area of responsibility and regularly reports to the full Board. The Board uses our enterprise-wide risk management system as a key tool for understanding the risks facing us as well as assessing whether management’s processes, procedures and practices for mitigating those risks are effective. Our General Counsel is the primary person responsible to the Board in the planning, assessment and reporting of our risk profile and this risk management system. The Board reviews and discusses an assessment of and a report on our risk profile on a regular basis, including reports on strategic, operational, financial, cybersecurity, information technology, and legal and regulatory compliance risks.

CORPORATE GOVERNANCE MATTERS

Oversight of Company Strategy

At least once per year, the Board and senior management engage in an in-depth strategic review of our company’s outlook and strategy, which is designed to create long-term shareholder value and serves as the foundation

upon which goals are established. Throughout the year, the Board reviews our strategy and monitors management’s progress against such goals.

Oversight of Succession Planning

The Board views its role in succession planning and talent development as a key responsibility. At least once per year, usually as part of the annual talent review process, the Board discusses and reviews the succession plans for the Chief Executive Officer position and other executive officers and key contributors. The Board becomes familiar with potential successors for key

management positions through various means, including annual talent reviews, presentations to the Board, and communications outside of meetings. Our succession planning process is an organization-wide practice designed to proactively identify, develop and retain the leadership talent that is critical for our future business success.

Communicating with Shareholders and Other Stakeholders

We believe that maintaining an active dialogue with our shareholders is important to our long-term success. We value the opinions of our shareholders and other stakeholders and welcome their views throughout the year on key issues. During 2021, we continued our shareholder outreach efforts with respect to corporate governance, executive compensation and ESG matters by initiating communications with our largest shareholders representing a majority of our outstanding shares. The majority of shareholders with whom we spoke supported

our corporate governance practices and executive compensation program, and shareholders have expressed their support for our ESG initiatives. If you wish to communicate with the Board, non-employee directors as a group, or any individual director, including the Chairman, you may send a letter addressed to the relevant party, c/o Corporate Secretary, Pentair plc, Regal House, 70 London Road, Twickenham, London, TW1 3QS, United Kingdom. Any such communications will be forwarded directly to the relevant addressee(s).

Policies and Procedures Regarding Related Person Transactions

Our Board has adopted written policies and procedures regarding related person transactions. For purposes of these policies and procedures:

▶

a “related person” means any of our directors, executive officers, or 5% shareholders or any of their immediate family members; and

▶

a “related person transaction” generally is a transaction with us in which a related person has a direct or indirect material interest and the amount will or may reasonably be expected to exceed $120,000 in any fiscal year.

Potential related person transactions must be disclosed and brought to the attention of the Governance Committee directly or to the General Counsel for transmission to the Governance Committee. The Governance Committee will review all related person transactions and either approve or disapprove of the entry into the related person transaction, which will occur in advance of entry into the related person transaction

whenever reasonably possible. In determining whether to approve a related person transaction, the Governance Committee will consider the following factors, among others, to the extent deemed relevant by the Governance Committee:

▶

the nature and extent of the related person’s interest in the transaction;

▶

whether the terms of the related person transaction are fair to us and on terms at least as favorable as would apply if the other party had no affiliation with any of our directors, executive officers or 5% shareholders;

▶

whether there are demonstrable business reasons for us to enter into the related person transaction;

▶

whether the related person transaction could impair the independence of a director under our Corporate Governance Principles’ standards for director independence;

Pentair plc 21

TABLE OF CONTENTS

CORPORATE GOVERNANCE MATTERS

▶

whether the related person transaction would present an improper conflict of interest for any of our directors or executive officers, taking into account the size of the transaction and the overall financial position of the director or executive officer; and

▶

the direct or indirect nature of the interest of the director or executive officer in the transaction, the ongoing nature of the relationship, and any other factors the Governance Committee deems relevant.

The Governance Committee will not approve or ratify any related person transaction that is inconsistent with our interests or those of our shareholders.

We had no related person transactions during 2021. To our knowledge, no related person transactions are currently proposed.

BOARD STRUCTURE AND PROCESSES

We and our Board are committed to the highest standards of corporate governance and ethics. As part of this commitment, the Board has adopted a set of Corporate Governance Principles that sets forth our policies on:

▶

selection and composition of the Board;

▶

Board leadership;

▶

Board composition and performance;

▶

responsibilities of the Board;

▶

the Board’s relationship to senior management;

▶

meeting procedures;

▶

committee matters; and

▶

succession planning and leadership development.

The Board regularly reviews and, if appropriate, revises the Corporate Governance Principles and other governance instruments, including the charters of its Audit and Finance, Compensation, and Governance Committees, in accordance with rules of the Securities and Exchange Commission (“SEC”), the NYSE and Irish law. The Board has also adopted a Code of Business Conduct and Ethics that applies to all of our employees, contractors, directors and executive officers, including our Chief Executive Officer and senior financial officers.

Copies of these documents are available, free of charge, on our website at https://www.pentair.com/en-us/
about/corporate-governance.html.

Board Leadership Structure

We do not have a policy requiring the positions of Chairman of the Board and Chief Executive Officer to be held by different persons. Rather, the Board has the discretion to determine whether the positions should be combined or separated. Since 2018, the positions of Chief Executive Officer and Chairman of the Board have been separated.

Mr. Stauch is our Chief Executive Officer, and Mr. Jones, an independent member of the Board, serves as Chairman of the Board. The role of the Chairman is to provide independent leadership to the Board, act as liaison between and among the non-employee directors and our company, and seek to ensure that the Board operates independently of management. The Chairman’s principal responsibilities include:

▶

leading meetings of the Board;

▶

presiding over all executive sessions of the Board;

▶

in conjunction with the Chair of the Compensation Committee, reporting to the Chief Executive Officer on the Board’s annual review of his performance;

▶

approving the agenda for Board meetings, including scheduling to assure sufficient time for discussion of all agenda items;

▶

in conjunction with the Committee Chairs, ensuring an appropriate flow of information to the Board;

▶

holding one-on-one discussions with individual directors when requested by directors or the Board; and

▶

carrying out other duties as requested by the Board.

Board and Committee Self-Assessments

The Board annually conducts a self-assessment of the Board and each committee in addition to verbal assessments conducted in independent executive session at the end of Board and committee meetings. In 2021, the annual assessment process consisted of

individual meetings with the Chairman and each director to discuss his or her assessment of the Board, and a written evaluation of the Board and each committee by its members comprising both quantitative scoring and narrative comments on a range of topics, including:

The results of the written Board evaluations were shared with the Chairman of the Board and Governance Committee Chair who led a discussion of the assessment at the following Board meeting.

Board Education

Board education is an ongoing, year-round process, which begins when a director joins our Board. Upon joining our Board, new directors are provided with a comprehensive orientation to our company, including our business, strategy and governance. For example, new directors typically participate in one-on-one introductory meetings with our senior business and functional

leaders. On an ongoing basis, directors receive presentations on a variety of topics related to their work on the Board and within the industry, both from senior management and from experts outside of our company. Directors may also enroll in continuing education programs sponsored by third parties at our expense.

DIRECTOR COMPENSATION

The Governance Committee annually reviews the compensation of our non-employee directors and makes recommendations to the Board. Our independent directors approve our director compensation.

We use a combination of cash and equity-based incentive compensation to attract and retain qualified directors. Compensation of our directors reflects our belief that a significant portion of directors’ compensation should be tied to long-term growth in shareholder value.

In September 2021, the Board adopted a Products and Services Program for Directors. The program is intended

to encourage the use and promotion of Pentair’s products and service offerings by our directors, and for our directors to have first-hand knowledge of our customers’ experiences. Directors are eligible for a maximum of $20,000 of products and services annually; we cover sales taxes on the products and services and directors are responsible for paying associated income taxes.

Mr. Stauch, our only employee-director, is not, and will not be, separately compensated for service as a member of the Board.

Director Retainers

The annual retainers for non-employee directors’ service on the Board and Board Committees during 2021 were as follows:

Board Retainer	$	90,000
Non-Employee Director Chair	$	140,000
Audit and Finance Committee Chair Supplemental Retainer	$	22,750
Compensation Committee Chair Supplemental Retainer	$	15,000
Governance Committee Chair Supplemental Retainer	$	15,000
Audit and Finance Committee Retainer	$	13,500
Compensation Committee Retainer	$	7,500
Governance Committee Retainer	$	7,500

The above fee structure was reviewed and re-approved by our independent directors in December 2020 based on recommendations from the Governance Committee and from Aon Consulting who reviewed our director compensation practices against the practices of our peer group. We also previously adopted a policy to provide, beginning in 2019, a tax equalization payment to non-employee directors on any U.K. taxes that may be paid on account of our company’s payment of, or reimbursement for, travel, lodging and meal expenses incidental to Board and Board Committee meetings and reimbursement of fees and expenses in connection with assistance in the preparation of U.K. tax returns and any U.K. taxes on such payment or reimbursement. In addition, for the purposes of limiting double-taxation on U.K. sourced income, non-employee directors are eligible to receive tax equalization payments if the income

taxes owed on U.K. sourced income exceeds the income tax rates relative to their countries of residence.

In December 2021, Aon Consulting again reviewed our director compensation with the Governance Committee based on the director compensation practices of our peer group. Based on this review, our independent directors approved the following changes to director compensation effective January 1, 2022:

▶

Board Retainer: increased to $95,000;

▶

Chairman and Committee Chair Supplemental Retainers increased to: Non-executive Chair: $155,000; Audit Committee Chair: $25,000; Compensation Committee Chair: $20,000; and Governance Committee Chair: $20,000.

The Committee member retainers remained the same.

Equity Awards

Non-employee directors receive an annual equity grant as a part of their compensation. The full value of the annual equity grant is delivered in the form of restricted stock units. The restricted stock units vest on the first anniversary of the grant date. Each restricted stock unit represents the right to receive one ordinary share upon vesting. The restricted stock units accrue dividend equivalents that will be paid out in ordinary shares if and when the award vests.

The annual grant for 2021, as approved by our independent directors based on the recommendation from the Governance Committee, was valued at $140,000 and was granted on January 4, 2021. Based on the review of director compensation by Aon Consulting and the recommendation of the Governance Committee, our independent directors approved an annual grant for 2022 valued at $150,000, which was granted on January 3, 2022.

Stock Ownership Guidelines for Non-Employee Directors

Our Corporate Governance Principles establish that non-employee directors should acquire and hold our company shares or share equivalents at a level of five times the annual board retainer.

PROPOSAL 2

EXECUTIVE COMPENSATION

				APPROVE, BY NONBINDING, ADVISORY VOTE, THE COMPENSATION OF THE NAMED EXECUTIVE OFFICERS
							The Board recommends a •vote FOR approval of the compensation of the Named Executive Officers
							See discussion beginning on page 32 for further information about the compensation of the Named Executive Officers

In accordance with Section 14A of the Securities Exchange Act of 1934, the Board is asking the shareholders to approve, by nonbinding, advisory vote, the compensation of the Named Executive Officers disclosed in the sections below titled “Compensation Discussion and Analysis” and “Executive Compensation Tables.” We currently hold these votes annually.

Executive compensation is an important matter to the Board and the Compensation Committee and to our shareholders. We have designed our executive compensation program to align executive and shareholder interests by rewarding the achievement of specific annual, long-term, and strategic goals that create long-term shareholder value. We believe that our executive compensation program provides competitive compensation that motivates and rewards executives for achieving financial and strategic objectives, provides rewards commensurate with performance to incentivize the Named Executive Officers to perform at their highest levels, encourages growth and innovation, attracts and retains the Named Executive Officers and other key executives, and aligns our executive compensation with shareholders’ interests through the use of equity-based incentive awards.

The Compensation Committee has overseen the development and implementation of our executive compensation program in line with these compensation objectives. The Compensation Committee continuously reviews, evaluates and updates our executive compensation program to ensure that we provide competitive compensation that motivates the Named Executive Officers to perform at their highest levels while increasing long-term value to our shareholders.

	With these compensation objectives in mind, the Compensation Committee has taken a number of compensation actions in recent years to align with our shareholders’ interests, including the following:
	▶ Annual cash incentives for the Named Executive Officers are based on performance goals that

	correlate strongly with several primary corporate objectives: focusing on revenue growth, improving the financial return from our business and strengthening our balance sheet through cash flow improvement and debt reduction.
	▶ Long-term incentive awards that are performance based and aligned with creating long-term shareholder value. ▶ Robust stock ownership guidelines for Named Executive Officers. ▶ No single trigger change in control vesting or excise tax gross-ups in our Key Executive Employment and Separation Agreements (“KEESAs”). ▶ Enhanced policy prohibiting hedging by directors, executive officers, and employees. ▶ Introduced an ESG component for Named Executive Officers in the annual incentive plan beginning in 2022.

As described in detail under “Compensation Discussion and Analysis — Shareholder Outreach and Say on Pay,” we continued our shareholder outreach on this and other matters in 2021.

These and other actions demonstrate our continued commitment to align executive compensation with shareholders’ interests while providing competitive compensation to attract, motivate and retain the Named Executive Officers and other key executives. We will continue to review and adjust our executive compensation program with these goals in mind to ensure the long-term success of our company and generate increased long-term value to our shareholders.

This nonbinding, advisory vote gives you an opportunity to express your views about our executive compensation program. As we further align our executive compensation program with the interests of our shareholders while continuing to retain key talented executives who drive our company’s success, we ask that you approve the compensation of the Named Executive Officers.

OVERVIEW OF COMPENSATION PROGRAM AND OBJECTIVES

The Compensation Committee sets and administers the policies that govern our executive compensation, including:

▶

establishing and reviewing executive base salaries;

▶

overseeing our annual incentive compensation plans;

▶

overseeing our long-term equity-based compensation plan;

▶

approving all awards under those plans;

▶

annually evaluating risk considerations associated with our executive compensation program; and

▶

annually approving all compensation decisions for executive officers, including those for the Named Executive Officers, who are named in the Summary Compensation Table below.

The Compensation Committee’s specific objectives include:

▶

motivating and rewarding executives for achieving financial and strategic objectives;

▶

aligning management and shareholder interests by encouraging employee stock ownership;

▶

providing rewards commensurate with company performance;

▶

encouraging growth and innovation; and

▶

attracting and retaining top-quality executives and key employees.

To balance the objectives described above, our executive compensation program uses the following direct compensation elements:

▶

base salary, to provide fixed compensation competitive in the marketplace;

▶

annual incentive compensation, to reward short-term performance against specific financial targets; and

▶

long-term incentive compensation, to link management incentives to long-term value creation and shareholder return.

We also provide standard retirement and health and welfare benefits to attract and retain executives over the longer term.

The Compensation Committee reviews total compensation for executive officers and the relative levels of each of these forms of compensation against the Committee’s goals. As such, our executive compensation program is predominantly performance-based, which encourages our executive officers to focus on our company’s long-term success and aligns with the long-term interests of our shareholders. The approximate mix of total target direct compensation for 2021 for our Chief Executive Officer and the average of the other Named Executive Officers is shown in the charts that follow.

2021 HIGHLIGHTS AND BUSINESS RESULTS*

In 2021, we delivered record revenue growth, income growth, and free cash flow results across our businesses, amidst challenging supply chain, inflationary, and labor environments. We remained committed to our strategies through our continued focus in our strategic growth initiatives and the completion of two acquisitions, Ken’s

Beverage, Inc. and Pleatco Holdings, LLC and related entities. Also, we announced our Social Responsibility Strategic Targets, highlighting our objective to be a leading socially responsible company that delivers smart, sustainable solutions that empower customers and employees to make the most of life’s essential resources.

Please see Appendix A for reconciliation of GAAP to non-GAAP financial measures included in this section.

Summary 2021 Financial Results

In 2021, as compared to 2020, we increased our adjusted earnings per share from continuing operations by 36.0%. Our sales during 2021 were $3,765 million, growing by 24.8%. Our segment income in 2021 grew 32.5% to $686 million for 2021. Our free cash flow from continuing operations was $557 million for 2021.

EVOLUTION OF EXECUTIVE COMPENSATION PROGRAM

The Compensation Committee reviews annually the effectiveness of our executive compensation program and considers a number of factors, including business results, strategic priorities, shareholder alignment, and market practice. As a result of the evolution of our compensation program and changes we have made in response to market dynamics and shareholder feedback, key aspects of our current executive compensation program include:

▶

50% of the value of long-term incentive awards are delivered in the form of performance-based restricted stock units;

▶

100% of our annual incentive metrics are tied to business results; and

▶

Our stock ownership requirements generally meet or exceed market levels.

COMPENSATION DISCUSSION AND ANALYSIS

The chart below highlights additional changes adopted over the last three years:

		2019				2020				2021
		▶ Reduced maximum payout opportunity on segment income under the 2019 MIP from 300% to 200% ▶ Replaced ROE with return on invested capital (“ROIC”) as a 2019-2021 performance share unit (“PSU”) metric ▶ Enhanced policy prohibiting hedging by directors, executive officers and employees				▶ Adopted Executive Officer Severance Plan				▶ Adopted program permitting directors and executive officers to access and use our products and services to better understand our business offerings ▶ Introduced an ESG component for executive officers in the annual incentive plan beginning in 2022

SHAREHOLDER OUTREACH AND SAY ON PAY

The Compensation Committee believes it is important to maintain an open dialogue with our shareholders to gain input on their perspectives regarding our governance and our executive compensation program and to provide clarifying information enabling them to make informed decisions in our annual advisory shareholder vote (our “say on pay vote”) on the compensation of our executive officers named in our Proxy Statement.

In 2021, we maintained our shareholder outreach to gain additional insight, better understand shareholder perspectives, and evaluate any concerns regarding our executive compensation program. Specifically, our outreach in 2021 consisted of initiating communications with our largest shareholders representing a majority of our outstanding shares. These shareholders either arranged for individual discussions with us or provided us with feedback that they did not require a meeting.

The majority of shareholders with whom we spoke supported our executive compensation program and the changes adopted over the last several years. This support was reflected in the results of the say on pay vote at the 2021 Annual General Meeting, with approximately 91% of votes cast in favor of our proposal.

Shareholder feedback is an important factor in how we approach and evaluate our executive compensation

program. Consistent with the strong vote of shareholder approval, and support from our shareholders, we did not make any material changes to our compensation programs in 2021, other than incorporating an ESG component to the annual incentive plan beginning in 2022. We expect to carry forward the general themes provided in the feedback, which include:

Themes

▶

Changes to our executive compensation program in recent years were viewed positively and balanced market practice with alignment to Pentair’s strategic objectives.

▶

Our executive compensation program demonstrates a pay-for-performance linkage and shareholder alignment, and is appropriately risk-based, balancing annual and long-term performance.

▶

Our annual incentive plan measures of income, revenue and free cash flow, and long-term incentive plan measures of adjusted EPS and ROIC are generally aligned with shareholder interests. Also, consistent with feedback from shareholders, our annual incentive plan will incorporate an ESG component for executive officers beginning in 2022.

COMPARATIVE FRAMEWORK

In setting compensation for our executive officers, including our Named Executive Officers, the Compensation Committee uses competitive compensation data from an annual total compensation study of selected peer companies and other relevant survey sources to inform its decisions about overall compensation opportunities and specific compensation elements. The Compensation Committee uses multiple

reference points when establishing targeted compensation levels. The Compensation Committee applies judgment and discretion in establishing targeted pay levels, taking into account not only competitive market data, but also factors such as company, business unit and individual performance, scope of responsibility,

COMPENSATION DISCUSSION AND ANALYSIS

critical needs and skill sets, experience, leadership potential, and succession planning. All companies in our peer group are:

▶

publicly-traded on a major exchange;

▶

similar in business scope and/or operations to our business units and global in nature; and

▶

range from 1∕2 to 2x our revenue size and in the same competitive sectors.

Considering Aon Consulting’s assessment, the Compensation Committee maintained the same group of companies for benchmarking purposes (the “Comparator Group”) for use in setting target compensation for 2021 for our executive officers, including our Named Executive Officers. Our Comparator Group for 2021 included the following 16 peer companies, which had revenues ranging from approximately $1.51 billion to $5.25 billion, with median revenues of approximately $3.14 billion:

Acuity Brands, Inc.	A.O. Smith Corporation	Colfax Corporation
Crane Co.	Donaldson Company, Inc.	Flowserve Corporation
Graco Inc.	IDEX Corporation	Lennox International Inc.
Lincoln Electric Holdings, Inc.	SPX FLOW, Inc.	Snap-on Incorporated
The Timken Company	Valmont Industries, Inc.	Watts Water Technologies, Inc.
Xylem Inc.

In December of 2021, the Committee approved an updated Comparator Group for use in setting target compensation for 2022 for our executive officers, including the Named Executive Officers. The changes to the Comparator Group reflect Pentair’s increased revenues in recent years and its growth trajectory. The new Comparator Group companies had revenues ranging from approximately $2.35 billion to $7.18 billion, with median revenues of approximately $3.68 billion:

Acuity Brands, Inc.	A.O. Smith Corporation	Colfax Corporation
Crane Co.	Donaldson Company, Inc.	Dover Corporations
Flowserve Corporation	Fortive Corporation	Fortune Brands Home & Security
IDEX Corporation	Ingersoll Rand Inc.	Lennox International Inc.
Lincoln Electric Holdings, Inc.	Masco Corporation	Owens Corning
Rockwell Automation, Inc.	Snap-on Incorporated	The Timken Company
Valmont Industries, Inc.	Xylem Inc.

2021 COMPENSATION PROGRAM ELEMENTS

For 2021, the principal components of compensation for our Named Executive Officers were:

▶

base salary;

▶

annual incentive compensation;

▶

long-term incentive compensation, consisting of stock options, restricted stock units and performance share units; and

▶

retirement and health and welfare benefits.

The Compensation Committee reviews total compensation for executive officers and the relative levels of each of these forms of compensation against the Compensation Committee’s goals to attract, retain and incentivize talented executives and to align the interests of these executives with those of our long-term shareholders.

COMPENSATION DISCUSSION AND ANALYSIS

BASE SALARIES

We provide each Named Executive Officer with a fixed base salary. In setting base salaries, the Compensation Committee generally references comparable positions at peer companies based on available market data, which include published survey data and proxy statement data for our Comparator Group. The Compensation Committee considers compensation at comparable companies but does not set base salaries based on a particular peer group benchmark or any single factor.

Base salaries for the Named Executive Officers are determined by the Compensation Committee based on numerous factors such as competitive conditions for the Named Executive Officer’s position within the Comparator Group and in the broader employment

market, as well as the Named Executive Officer’s level of responsibility, experience, and individual performance.

In December 2020, the Compensation Committee undertook its annual review of base salaries for executive officers and other management personnel, in accordance with its normal procedures. Following a review with Aon Consulting, the Compensation Committee approved annual salary increases ranging from 2.3% to 3.6% for Messrs. Stauch, Fishman, D’Ovidio, and Pedretti. Ms. Robertson received 8.3% in recognition of her expanded role as Chief Sustainability Officer. Increases became effective January 1, 2021 as set forth in the table below.

	2021 Base Salary			2020 Base Salary			Increase From 2020 to 2021
John L. Stauch		$	995,000		$	970,000		2.6%
Robert P. Fishman		$	665,000		$	650,000		2.3%
Mario R. D’Ovidio		$	615,000		$	600,000		2.5%
Karla C. Robertson		$	585,000		$	540,000		8.3%
Jerome O. Pedretti		$	570,000		$	550,000		3.6%

ANNUAL INCENTIVE COMPENSATION

To provide competitive compensation to attract and retain top talent while linking pay to annual performance, we pay a portion of our executives’ cash compensation as incentive compensation tied to annual business performance as measured against annual goals established by the Compensation Committee. In 2021, we provided a cash annual incentive compensation opportunity to each of our executive officers, including the Named Executive Officers, under our MIP.

The Compensation Committee determines a percentage of each executive officer’s base salary as a targeted level of incentive compensation opportunity under the MIP, based on the Compensation Committee’s review of Aon Consulting’s recommendations, relevant survey data and, in the case of executive officers other than the Chief Executive Officer, the recommendations of the Chief Executive Officer. The Compensation Committee generally sets each executive officer’s target incentive compensation opportunity taking into consideration the Comparator Group’s target payouts but does not set target incentive compensation opportunities based on a particular peer group benchmark or any single factor.

The actual target incentive compensation opportunity set by the Compensation Committee for each executive officer varies depending on a wide range of factors, including competitive conditions for the executive officer’s position within the Comparator Group and in the broader employment market, as well as the executive officer’s performance, level of responsibility, and experience. An executive officer’s base salary multiplied by the incentive compensation opportunity percentage establishes the target incentive compensation for which the executive officer is eligible.

In December 2020, the Compensation Committee undertook its annual review of targeted levels of incentive compensation opportunities and determined to maintain the same levels from the prior year for Messrs. Stauch, Fishman, D’Ovidio, and Pedretti, and Ms. Robertson.

The Named Executive Officers’ incentive compensation targets as a percentage of salary and as a dollar amount were as follows:

For the 2021 MIP, the Compensation Committee approved, based on recommendations of the Chief Executive Officer, the following performance measures, which applied to our Named Executive Officers except Mr. D’Ovidio and Mr. Pedretti: segment income, revenue, and free cash flow, each measured with respect to company-wide performance. For Mr. D’Ovidio, the MIP performance goals were specific to the Consumer Solutions segment, for which he had primary responsibility, as well as company-wide income

performance. For Mr. Pedretti, the MIP performance goals were specific to the Industrial & Flow Technologies segment, for which he had primary responsibility, as well as company-wide income performance.

2021 performance goals that applied to each of our Named Executive Officers, as well as the weight assigned to each performance goal and the corresponding payout levels were as follows:

Consistent with our continuous effort to align pay with performance, and in response to shareholder feedback that compensation should be tied to strategic financial and operating performance goals, Named Executive Officer annual incentive compensation does not include an individual contribution component. As such, annual incentive compensation for Named Executive Officers is

solely based on the achievement of financial performance goals.

The target levels for the performance goals were aligned with the corporate objectives in our annual operating plan. To provide an added performance incentive, the Compensation Committee determined that the amount of incentive compensation related to each

Pentair plc 39

TABLE OF CONTENTS

COMPENSATION DISCUSSION AND ANALYSIS

performance goal would be scaled according to the amount by which the measure exceeded or fell short of the target. The Compensation Committee reviews information about annual incentive plan design among peer companies and considers the need for the Company to ensure that performance goals are reasonably attainable to provide appropriate incentives for executive officers. As such, payouts for 2021 performance were scaled from 0.50 at threshold performance to 2.0 times at the maximum, as detailed in the tables above. In line with our long-term goal to consistently generate free cash flow that equals or exceeds 100 percent of net income, we set our 2021 cash flow target to equal 100 percent conversion of our forecast net income.

In assessing our performance against the financial targets, the Compensation Committee excluded the financial impacts (revenue and segment income contributions) of our acquisitions of Ken’s Beverage, Inc. and Pleatco Holdings, LLC and related entities since those acquisitions were not contemplated at the time the financial targets were set. These adjustments reduced the Company’s revenue and segment income by approximately $73 million and $2 million, respectively,

reduced the revenue and segment income of Consumer Solutions by approximately $68 million and $2 million, respectively, and reduced the revenue of Industrial & Flow Technologies by approximately $6 million. Our financial results yielded a payout at the maximum level of achievement for each executive officer except Mr. Pedretti and in that case resulted in a payout of 180% of target. While the financial results resulted in a payout at maximum both with and without the adjustment for acquisitions, the Compensation Committee determined to certify the results with the adjustment consistent with the philosophy that material impacts to results from events not contemplated at the beginning of the performance period should be excluded to ensure comparability against the original targets.

The actual incentive compensation of each Named Executive Officer was determined by multiplying the eligible target incentive compensation amount by a multiplier determined as described above. For 2021, actual results as measured by the performance goals under the MIP for each of our Named Executive Officers were as follows:

Company-wide Financial Performance Measure	Weight	Target (100% Payout)	Actual Financial Results	Payout %		Weighted Payout %

COMPENSATION DISCUSSION AND ANALYSIS

Revenue at the segment level represents segment gross sales less applicable deductions for discounts, returns, and price adjustments to arrive at net sales for the segment.

Free cash flow at the segment level represents net cash provided by operating activities of the segment, as adjusted, and is calculated as segment Income after tax plus depreciation and net changes in working capital accounts, less capital expenditures.

The calculation of MIP results will periodically require certain adjustments made by the Compensation Committee to ensure that payouts are based on metrics that are comparable to the metrics set at the beginning of the performance period.

Please see Appendix A for reconciliation of GAAP to non-GAAP financial measures included in this section.

Pentair is committed to building on our Win Right values and culture by contributing to the development of a sustainable and responsible society that we believe will also drive our future growth. Therefore, when establishing the 2022 MIP design, the Compensation Committee approved an ESG component addressing progress towards our strategic ESG targets on the final MIP financial calculation for executive officers.

This component is a modifier that may be applied to the MIP payout that is determined based on achievement of the revenue, income, and free cash flow financial targets, to increase or decrease such payout by up to 10%. In determining whether to approve any modifier, the Compensation Committee will consider our progress

towards our five strategic targets announced in 2021 — carbon footprint reduction, water reduction, product design for sustainability, responsible supply chain, and inclusion & diversity. Making progress toward these strategic targets is a baseline expectation, and the Compensation Committee expects to apply the modifier to increase or decrease the payout determined by the financial targets only for achievement well above or below overall expected progress. Threshold performance of financial targets must be met before any ESG modifier can be applied. In addition, the maximum payout for MIP is 200% of target, regardless of ESG performance.

2021 LONG-TERM INCENTIVE COMPENSATION

The Compensation Committee emphasizes executive compensation that is tied to building and sustaining our company’s value through ordinary share performance over time.

[MISSING IMAGE: tm2134300d1-pc_equmixpn.jpg]

The Compensation Committee establishes long-term incentive compensation targets taking into consideration both published survey data and data from our Comparator Group. The Compensation Committee does not set award levels based on a particular peer group benchmark or any single factor. The Compensation Committee determines appropriate performance incentives based on a wide range of factors, such as competitive conditions for the Named Executive Officer’s position within the Comparator Group and in the broader employment market, as well as the Named

Executive Officer’s level of responsibility, experience, and individual performance.

As it does each year, in determining 2021 long-term incentive compensation, the Compensation Committee referenced benchmark data (including compensation surveys, Comparator Group information and other data provided by Aon Consulting) in setting target dollar award levels for each Named Executive Officer and for each position or grade level.

As in prior years, the Compensation Committee continued to balance our long-term incentive compensation program components in a manner focused on shareholder wealth creation, the creation of a sustainable business, and ensuring the leadership is committed to the long-term success of our company.

For 2021, the Compensation Committee maintained the mix of long-term incentive award of performance share units at 50% of the total long-term award value and stock options and restricted stock units each at 25% of the total long-term award value as described below. The components had the features described below.

▶

Stock options — Each stock option has a term of ten years, with one-third of the options vesting on each of the first, second, and third anniversaries of the grant date.

Pentair plc 41

TABLE OF CONTENTS

COMPENSATION DISCUSSION AND ANALYSIS

▶

Restricted stock units — Each restricted stock unit represents the right to receive one ordinary share upon vesting. The restricted stock units generally vest as to one-third of the restricted stock units on each of the first, second, and third anniversaries of the grant date. Restricted stock units granted after May 2020 accrue dividend equivalents that will be paid out in ordinary shares if and when the award vests. Earlier restricted stock units entitled the holder to receive cash dividends on the units when dividends were declared.

▶

Performance share units — Each performance share unit represents the right to receive one ordinary share at the end of a three-year performance period if specified performance goals are achieved. For the performance share units granted in 2021 for the performance period 2021-2023, the Compensation Committee retained adjusted EPS and ROIC as the performance goals.

The Compensation Committee selected these metrics because of their relationship to driving long-term shareholder value and alignment with business strategy. The Compensation Committee believes that, while long-term interests should be reflected in performance-based awards, the targets should also be realistic and

attainable. As such, the Compensation Committee set performance metrics for the 2021-2023 PSUs based on adjusted EPS and ROIC targets aligned with the growth objectives as defined within Pentair’s strategic plan, including payouts at Threshold levels that would pay out only at minimum Adjusted EPS growth and minimum ROIC performance. Payouts would be based on achievement of the threshold, target and maximum level of performance set for each metric, with payouts scaled for performance between those levels.

The numbers of shares subject to the stock options, restricted stock units and performance share units and the values of the awards granted to the Named Executive Officers in 2021 are reflected under “Executive Compensation Tables — Grants of Plan-Based Awards in 2021.”

The value of restricted stock units that vested for each Named Executive Officer in 2021 and the value of options exercised by each Named Executive Officer in 2021 are shown in the table under “Executive Compensation Tables — 2021 Option Exercises and Stock Vested Table.”

Achievement under 2019-2021 PSUs

The Compensation Committee granted stock settled performance share units to the Named Executive Officers in 2019, relating to the three-year performance period 2019-2021. Each performance unit entitled the holder to one ordinary share following the end of the three-year performance period if we achieved specific company performance goals on metrics established by the Compensation Committee. The performance goals selected by the Compensation Committee for the 2019-2021 performance period were Adjusted EPS and

ROIC, weighted 75% and 25% respectively. Payouts would be scaled for performance between threshold and target and between target and maximum.

The Compensation Committee reviewed and approved the performance share units for the 2019-2021 performance period as reflected in the chart below.

The payout levels for 2019-2021 PSUs were as follows:

Financial Performance Measure	Weight		Threshold (50% Payout)			Target (100% payout)			Maximum (200% payout)			Actual			Actual Weighted Payout (% of Target)
Adjusted EPS*		75%		$	2.72		$	3.13		$	4.06		$	3.40		98.3%
ROIC**		25%	17.5%			18.2%			21.2%			19.3%				34.1%
2019-2021 Total Weighted Performance		100%														132.4%

Adjusted EPS is determined based on full year 2021 adjusted earnings per diluted share from continuing operations.

ROIC is determined by the sum of the trailing four quarters of Segment Income after tax plus depreciation less capital expenditures for the quarters ended March 31, June 30, September 30 and December 31, 2021 divided by the average of the trailing five quarters invested capital (Total Shareholders’ Equity + Long-term Debt + Current Maturities of Long-term Debt and Short-term Borrowings — Cash and Cash Equivalents) as of December 31, 2021.

PERQUISITES AND OTHER PERSONAL BENEFITS

The Compensation Committee periodically reviews market data provided by Aon Consulting to assess the levels of perquisites and other personal benefits provided to the Named Executive Officers.

We provide our executive officers with limited perquisites in the form of occasional personal use of event tickets when such tickets are not being used for business purposes and a limited financial counseling benefit, for which, in both cases, we have no aggregate incremental cost, as well as one executive physical per year for preventative care.

In September 2021, the Compensation Committee adopted a Products and Services Program for Executives. The program is intended to encourage the use and promotion of Pentair’s products and service offerings by our executives, and to give our executive officers first-hand knowledge of our customers’ experiences. Executive officers are eligible for a maximum of $20,000 of products and services annually; Pentair covers sales taxes on the products and services; and executive officers are responsible for paying associated income taxes.

STOCK OWNERSHIP GUIDELINES

The Compensation Committee has established stock ownership guidelines for the Named Executive Officers and other executives to motivate them to become significant shareholders, to further encourage long-term performance and growth, and to align their interests with those of shareholders generally. The Compensation Committee monitors executives’ compliance with these guidelines and periodically reviews the definition of “stock ownership” to reflect the practices of companies in the Comparator Group. “Stock ownership” currently includes ordinary shares owned by the executive officers both

directly and indirectly, the pro-rated portion of unvested restricted stock units, and shares held in our employee stock ownership plan or our employee stock purchase plan. Stock ownership does not include performance share units until they are earned at the end of the performance period. The Compensation Committee determined that, over a period of five years from appointment, certain executives should accumulate and hold ordinary shares equal to specified multiples of their base salaries.

	Executive Level			Stock Ownership Guidelines (as a multiple of salary)
	Chief Executive Officer			6.0x base salary
	Executive Vice President and Chief Financial Officer & CAO			3.0x base salary
	Executive Vice President and Chief Human Resources Officer and Chief Transformation Officer Executive Vice President and General Counsel, Secretary and Chief Social Responsibility Officer Executive Vice President and Chief Growth Officer Executive Vice President and Chief Technology Officer Executive Vice President and Chief Supply Chain Officer Segment Presidents			2.5x base salary

(1)

The amounts in this column were calculated by multiplying the closing market price of our ordinary shares on the last trading day of our most recently completed fiscal year of $73.03 by the number of shares owned.

(2)

Per the terms of our stock ownership guidelines, an executive has five years from the date of his or her appointment to meet his or her ownership guideline. Mr. Fishman and Mr. D’Ovidio joined the Company within the last five years; thus, neither of these Named Executive Officers was required to have met the applicable ownership guidelines as of December 31, 2021. All other Named Executive Officers meet these guidelines.

[MISSING IMAGE: tm2134300d1-bc_shareownpn.jpg]

EQUITY HOLDING POLICY

We maintain an equity holding policy under which executive officers subject to our share ownership guidelines are required to retain 100% of the net number of shares acquired under equity awards until the

ownership guidelines are satisfied. This policy may be waived to the extent its application to any individual executive officer would cause undue hardship to the executive officer.

CLAWBACK POLICY

We maintain a clawback policy under which certain incentive compensation earned by an executive officer may be recouped if the executive officer’s fraud or intentional misconduct is a significant contributing factor to a restatement of financial results. The incentive compensation subject to this policy includes cash

bonuses, cash performance units and equity-based awards subject to performance-based vesting conditions to the extent the compensation was paid, credited or earned during the year after the financial results were first disclosed.

POLICY PROHIBITING HEDGING AND PLEDGING

We maintain a policy that prohibits our executive officers, directors and other employees from purchasing financial instruments (including prepaid variable forward contracts, equity swaps, collars and exchange funds) or otherwise engaging in transactions that hedge or offset, or are designed to hedge or offset, any decrease in the market value of Pentair securities. Prohibited transactions include transactions in puts,

calls, cashless collars, options (other than options issued by Pentair to acquire Pentair securities), short sales and similar rights and obligations. This restriction applies to all Pentair securities owned directly or indirectly by the individual, including Pentair securities owned by their family members and their respective designees. Nothing in our policy precludes an executive officer, director or employee or their designees from engaging

in general portfolio diversification or investing in broad-based index funds. In addition, our executive officers, directors and other employees and their family

members are also prohibited from holding Pentair securities in a margin account or otherwise pledging Pentair securities as collateral for a loan.

RETIREMENT AND OTHER BENEFITS

Eligible Named Executive Officers and other executives and employees participate in a number of retirement and similar plans that are described below under “Executive Compensation Tables — 2021 Pension Benefits.” We also provide other benefits such as medical, dental, life

insurance and disability coverage to substantially all of our full-time U.S. salaried employees, including the Named Executive Officers. We aim to provide employee and executive benefits that are competitive in the market.

Medical, Dental, Life Insurance and Disability Coverage

Employee benefits such as medical, dental, life insurance and disability coverage are available to all full-time U.S.-based employees through our active employee plans. In addition to these benefits for active employees, we provide post-retirement medical, dental and life insurance coverage to certain retirees in accordance with the legacy company plans that applied at the time the

employees were hired. We provide up to one and one-half times annual salary (up to $1,000,000) in life insurance, and up to $15,000 per month in long-term disability coverage. The value of these benefits is not required to be included in the Summary Compensation Table because they are made available to all full-time U.S. employees.

Other Paid Time-Off Benefits

We also provide vacation and other paid holidays to all employees, including the Named Executive Officers, which we have determined to be comparable to those provided at other large companies.

Deferred Compensation

We sponsor a non-qualified deferred compensation program, called the Sidekick Plan, for our U.S. executives within or above the pay grade that has a midpoint annual salary of $201,000 in 2021. This plan permits executives to defer up to 25% of their base salary and 75% of their annual cash incentive compensation. Executives also may defer receipt of restricted stock units or performance share units. We normally make contributions to the Sidekick Plan on behalf of participants with respect to each participant’s contributions from that portion of his or her income above the maximum imposed by the U.S. Internal Revenue Code of 1986, as amended (the “Code”), which was $290,000 in 2021, but below the Sidekick Plan’s compensation limit of $700,000. Please see the narrative following the “Nonqualified Deferred Compensation Table” below for additional information on our contributions.

Participants in the Sidekick Plan may invest their account balances in a number of possible mutual fund investments. Fidelity Investments Institutional Services Co. provides these investment vehicles for participants and handles all allocation and accounting services for the Sidekick Plan. We do not guarantee or subsidize any investment earnings under the Sidekick Plan, and our ordinary shares are not a permitted investment choice under the Sidekick Plan, although deferred restricted stock units and performance share units are automatically invested in Pentair shares.

Amounts deferred, if any, under the Sidekick Plan by the Named Executive Officers are included in the “Salary” and “Non-Equity Incentive Plan Compensation” columns in the Summary Compensation Table. Our contributions allocated to the Named Executive Officers under the Sidekick Plan are included in the “All Other Compensation” column in the Summary Compensation Table.

COMPENSATION DISCUSSION AND ANALYSIS

SEVERANCE AND CHANGE IN CONTROL BENEFITS

We provide severance and change in control benefits to selected executives to facilitate smooth executive transitions, attract and retain executive talent, and provide for continuity of management upon a threatened or completed change in control. We believe that the security that these benefits provide helps our key executives to remain focused on our ongoing business and reduces the key executives’ concerns about future employment. We also believe that these benefits allow our executives to consider the best interests of our company and shareholders due to the economic security afforded by these benefits. We currently provide the following severance and change in control benefits to our executive officers:

▶

We have agreements with our key corporate executives and other key leaders, including all Named Executive Officers, that provide for contingent benefits upon a change in control or upon a covered termination following a change in control. The benefits under these agreements are designed to provide economic protection to key executives following a change in control of our company so that our executives can remain focused on our business without undue personal concern.

▶

If after a change in control of the Company, an eligible employee is terminated by the Company other than by reason of death, disability or cause (as defined in the KEESA), then all options, restricted

stock and restricted stock units that are unvested become fully vested (e.g., double trigger vesting); all performance awards (other than annual incentive awards) are paid in full based on performance at the better of target or trend; and all annual incentive awards are paid based on full satisfaction of the performance goals (i.e., target). In addition, if an employee’s employment is involuntarily terminated for a reason other than cause, death or disability, or if an employee who is a Board-appointed corporate officer voluntarily terminates employment for good reason, then the employee’s outstanding awards will be eligible for continued or accelerated vesting as described below under “Executive Compensation Tables — Potential Payments Upon Termination Or Change In Control.”

▶

Our executive officer severance plan provides our executive officers with severance benefits in the event of certain types of terminations of employment (other than a termination following a change in control). The severance benefits are aligned with market practices and are designed to attract and retain executive talent. The plan is described in more detail below.

We explain these benefits more fully below under “Executive Compensation Tables — Potential Payments Upon Termination Or Change In Control.”

IMPACT OF TAX CONSIDERATIONS

Section 162(m) of the Code limits the amount we may deduct for compensation paid in any year to certain executive officers (“covered employees”) to $1,000,000. Section 162(m) exempted qualifying performance-based compensation with respect to taxable years

beginning on or before December 31, 2017 and payable pursuant to binding written agreements in effect on November 2, 2017. Since that time all compensation to covered employees has been subject to the $1,000,000 deduction limit.

COMPENSATION CONSULTANT

The Compensation Committee engages an external compensation consultant to advise the Compensation Committee in implementing and overseeing appropriate compensation programs and policies. The Compensation Committee regularly evaluates the performance of its external compensation consultant and periodically conducts a competitive bid process for the role.

During 2021, the Compensation Committee continued to retain Aon Consulting, an external compensation consultant, to advise the Compensation Committee on

executive compensation issues. See “Corporate Governance Matters — Committees of the Board — Compensation Committee.” The Compensation Committee evaluated the independence of Aon Consulting and the individual representatives of Aon Consulting who served as the Compensation Committee’s consultants based on the factors required by the NYSE. Aon Consulting is a wholly-owned subsidiary of Aon plc, which provides insurance brokerage and benefit consulting services to us. For the year ended December 31, 2021, we paid Aon plc

TABLE OF CONTENTS

COMPENSATION DISCUSSION AND ANALYSIS

approximately $1,421,000 for insurance brokerage and benefit consulting services and Aon Consulting approximately $203,300 for executive compensation consulting for the Compensation Committee. The decision to engage Aon plc for insurance brokerage and benefit consulting services was made by management and was not approved by the Board or the Compensation Committee. The Compensation Committee concluded, based on the evaluation described above, that the services performed by Aon plc with respect to insurance and benefits administration did not raise a conflict of interest or impair Aon Consulting’s ability to provide independent advice to the Compensation Committee regarding executive compensation matters and that Aon Consulting was independent for purposes of the Compensation Committee.

At the direction of the Compensation Committee, Aon Consulting advises the Compensation Committee in implementing and overseeing appropriate compensation programs and policies. As part of this process, Aon Consulting provides the Compensation Committee with comparative market data based on analyses of the practices of the Comparator Group defined above under “Comparative Framework” and relevant survey data. The comparative market data that Aon Consulting provides address the structure of the compensation programs maintained by the Comparator Group companies as well as the amount of compensation they provide. Aon Consulting provides guidance on industry best practices and advises the Compensation Committee in determining appropriate ranges for base salaries, annual incentive compensation and long-term incentive compensation for each senior executive position.

EVALUATING THE CHIEF EXECUTIVE OFFICER’S PERFORMANCE

In the fall of 2021, the independent directors on the Board and the Compensation Committee employed a formal process to evaluate Mr. Stauch’s performance. Each independent director provided an evaluation of Mr. Stauch’s performance. The Board Chairman and the Compensation Committee Chair discussed the evaluation results with the Compensation Committee and independent directors, and the independent directors reviewed and discussed the evaluation results and

Mr. Stauch’s compensation in executive session of the Board of Directors meeting. The Board Chairman and the Compensation Committee Chair finalized Mr. Stauch’s performance assessment and reviewed the assessment results and commentary with Mr. Stauch. The Compensation Committee determined Mr. Stauch’s compensation and performance targets for the following year.

EQUITY AWARD PRACTICES

The Compensation Committee reviews and approves equity awards to executive officers at regular meetings throughout the year. The Compensation Committee has also given the Chief Executive Officer discretion to grant equity awards to non-executive officers as required throughout the year (other than normal annual grants, which are granted by the Compensation Committee) within the guidelines of our equity incentive plan, up to a maximum grant date value of $2,000,000 total for 2021. The Chief Executive Officer provides a summary report to the Compensation Committee disclosing the

aggregate awards granted by the Chief Executive Officer during the preceding fiscal year. Awards granted outside of our regularly scheduled Compensation Committee meetings are generally effective on the last day of the month following the month in which they were approved. If the last day of such month is a day on which the NYSE is not open for trading, then the grant date will be the first day of the following month on which the NYSE is open for trading. All options are granted with an exercise price equal to fair market value based on the closing share price on the effective day of grant.

The Supplemental Executive Retirement Plan benefits, which include amounts under the Restoration Plan, are payable following retirement at age 55 or later in the form of an annuity. The actuarial present value above was calculated using the following methods and assumptions:

▶

Present values for the Supplemental Executive Retirement Plan are based on a 180-month certain-only annuity.

▶

The present value of Supplemental Executive Retirement Plan benefits as of December 31, 2021 was calculated assuming a 2.41% interest rate.

The Pentair, Inc. Retirement Savings and Stock Incentive Plan, the Pentair, Inc. Supplemental Executive Retirement Plan and the Pentair, Inc. Restoration Plan were all amended in 2008 to comply with final regulations under Section 409A of the Code. As a result of these

amendments, benefits vested prior to January 1, 2005 are separated from benefits earned after January 1, 2005, and may offer different distribution or other options to participants from those described below.

TABLE OF CONTENTS

EXECUTIVE COMPENSATION TABLES

The Pentair, Inc. Supplemental Executive Retirement and Restoration Plan

The Pentair, Inc. Supplemental Executive Retirement Plan (“SERP”) and the Pentair, Inc. Restoration Plan (“Restoration Plan”) are unfunded, nonqualified defined benefit pension plans. Employees eligible for participation in the SERP include all executive officers and other key executives selected for participation by the Compensation Committee. Participation in the Restoration Plan is limited to eligible employees under the SERP who were eligible employees on or before December 31, 2007. Benefits under these two plans vest upon the completion of five years of benefit service (all service following initial participation). These plans are combined for all administrative, accounting and other purposes. Of the Named Executive Officers, only Mr. Stauch participated in the SERP and the Restoration Plan. Mr. Stauch was fully vested in these plans during 2021.

Benefits under the SERP are based upon an employee’s years of service following initial participation and the highest average earnings for a five calendar-year period (ending with retirement). Compensation covered by the SERP and the Restoration Plan for Mr. Stauch equals the amount set forth in the “Salary” column in the Summary Compensation Table and incentive compensation paid under the MIP set forth in the “Non-Equity Incentive Plan Compensation” column in the Summary Compensation Table.

Benefits under the SERP are calculated as:

▶

final average compensation as defined above; multiplied by

▶

benefit service percentage, which equals 15% multiplied by years of benefit service.

The Restoration Plan is designed to provide retirement benefits based on compensation earned by participants

in excess of the annual limitation imposed by the Code, which was $290,000 in 2021.

Benefits under the Restoration Plan are calculated as:

▶

final average compensation as defined above, less compensation below the annual limitation amount in each year; multiplied by

▶

earned benefit service percentage (which is weighted based on age at the time of service), in accordance with the following table:

Service Age	Percentage
Under 25		4.0%
25-34		5.5%
35-44		7.0%
45-54		9.0%
55 or over		12.0%

The benefit percentages calculated above are added, and the resulting percentage is multiplied by the covered compensation amount. Benefits vested as of December 31, 2004 are payable after retirement in the form of a 15-year certain annuity or, at the participant’s option, a 100% joint and survivor annuity. Benefits earned after December 31, 2004 are payable after retirement in the form of a 15-year certain annuity. No additional benefits may be earned under the Restoration Plan after December 31, 2017.

The present value of the combined accumulated benefits for Mr. Stauch under both the SERP and the Restoration Plan is set forth in the 2021 Pension Benefits table.

The Pentair, Inc. Retirement Savings and Stock Incentive Plan

The Pentair, Inc. Retirement Savings and Stock Incentive Plan (“RSIP”) is a tax-qualified 401(k) retirement savings plan. Participating employees may contribute up to 50% of base salary and incentive compensation on a before-tax basis and 15% of compensation on an after-tax basis, into their RSIP accounts. We match an amount equal to one dollar for each dollar contributed to the RSIP by participating employees on the first 5% of their regular earnings on a before-tax basis to incent employees to make contributions to our retirement plan. The RSIP limits the amount of cash compensation

considered for contribution purposes to the maximum imposed by the Code, which was $290,000 in 2021.

Participants in the RSIP are allowed to invest their account balances in a number of possible mutual fund investments. Our ordinary shares are also a permitted investment choice under the RSIP.

Fidelity Investments Institutional Services Co. provides these investment vehicles for participants and handles all allocation and accounting services for the RSIP. We do not guarantee or subsidize any investment earnings under the RSIP.

Amounts contributed, if any, under the RSIP by the Named Executive Officers are included in the “Salary” and “Non-Equity Incentive Plan Compensation” columns in the Summary Compensation Table. Amounts

contributed by us to the RSIP for the Named Executive Officers are included in the “All Other Compensation” column in the Summary Compensation Table.

2021 NONQUALIFIED DEFERRED COMPENSATION TABLE

The following table sets forth the contributions, earnings, distributions and 2021 year-end balances for each of the Named Executive Officers under our Sidekick Plan described under “Compensation Discussion and Analysis — Retirement and Other Benefits — Deferred Compensation.” Contributions we make to the Sidekick Plan are intended to make up for contributions to our RSIP (including our matching contributions) for cash compensation above the maximum imposed by the Code, which was $290,000 in 2021. Because the Code does

not permit contributions on amounts in excess of that limit under a tax-qualified plan, the Sidekick Plan is designed to permit matching contributions on compensation in excess of the maximum imposed by the Code. We make these matching contributions to the Sidekick Plan on amounts in excess of the maximum imposed by the Code, but below the $700,000 compensation limit contained in our Sidekick Plan (such contributions by a Named Executive Officer, “Covered Sidekick Compensation”).

Amounts deferred under the Sidekick Plan that have also been reported in the Summary Compensation Table for fiscal 2021 or prior years for each Named Executive Officer are: Mr. Stauch — $7,085,931; Mr. Fishman — $275,207; Mr. D’Ovidio — $7,000; Ms. Robertson — $218,455; and Mr. Pedretti — $502,277.

The amounts set forth in the column “Executive Contributions in 2021” reflect the amount of cash compensation each Named Executive Officer deferred in 2021 under the Sidekick Plan.

The amounts set forth in the column “Registrant Contributions in 2021” are the totals of contributions we made in 2021 under the Sidekick Plan for the account of each Named Executive Officer. These amounts, in addition to contributions we made under the RSIP, are included in the Summary Compensation Table above in the column labeled “All Other Compensation.” The contributions we made are derived from matching contributions equal to one dollar for each dollar contributed up to 5% of Covered Sidekick Compensation deferred in 2020 by each Named Executive Officer; we normally make these contributions one year in arrears.

The amounts set forth in the column “Aggregate Earnings/(Loss) in 2021” reflect the amount of investment earnings realized by each Named Executive Officer on the investments chosen that are offered to participants in our RSIP and Sidekick Plan.

Fidelity Investments Institutional Services Co. provides these investment vehicles for participants and handles all allocation and accounting services for these plans. We do not guarantee or subsidize any investment earnings in either plan.

Amounts deferred under the Sidekick Plan are generally distributed on or after the earliest of the participant’s separation from service, the participant’s disability, a change in control, or a specified date elected by the participant.

POTENTIAL PAYMENTS UPON TERMINATION OR CHANGE IN CONTROL

Executive Officer Severance Plan

In December 2020, the Compensation Committee recommended and the independent members of the Board approved the Pentair plc Executive Officer Severance Plan (“Executive Severance Plan”) which became effective January 1, 2021. Under the Executive Severance Plan, our executives, including our Named Executive Officers, are eligible to receive severance benefits in the event of a qualifying termination of employment to the extent the terms and conditions of the Executive Severance Plan are satisfied. A qualifying termination occurs in the event of an executive’s involuntary termination without cause or resignation for good reason.

The severance benefits under the Executive Severance Plan provide for a cash payment equal to the product of the severance multiplier and the sum of the Named Executive Officer’s base salary and annual bonus target. The severance multiplier is two for the chief executive officer and any other executive officer as of January 1, 2021, and one and one half for anyone who becomes an executive officer thereafter, and the cash payments are made in equal installments over the corresponding period. If enrolled in the group medical and/or dental insurance coverage, the participant will receive an additional cash payment equal to the amount determined by multiplying the severance multiplier by the amount equal to the employer’s portion of the health and/or dental insurance premiums for one year. The participant is also eligible for outplacement services. As a condition for the severance benefits, the participant must sign an agreement under which they agree to sign a separation and release agreement and restrictive covenants agreement. The Compensation Committee and the independent members of the Board adopted the Executive Severance Plan to aid in the attraction and retention of executive talent. The Company retains the right to adjust the severance benefits available under the plan.

Under the Executive Severance Plan, “cause” means the officer’s:

▶

breach of any written agreement with the Company, including restrictive covenants which are not remedied;

▶

acts of dishonesty, fraud or breach of fiduciary duty;

▶

failure to satisfactorily perform duties of employment;

▶

violation of any anti-harassment, anti-discrimination or anti-retaliation policy of the Company; or

▶

misconduct.

Under the Executive Severance Plan, provided the officer provides us with 90 days’ written notice, “good reason” means:

▶

a breach of the Executive Severance Plan or employment agreement by us;

▶

the officer’s removal from, or any failure to reelect or reappoint him or her to any title or position as a corporate officer;

▶

a material diminution of the officer’s authority or responsibilities;

▶

a material reduction in an officer’s base salary (unless as part of a uniformly applied reduction for all executive officers); or

▶

relocation of an officer’s principal place of employment to a location more than 50 miles from his or her principal place of employment (other than a relocation to the Company’s management office in the U.S.).

Under the Executive Severance Plan, a “change in control” has the same meaning as defined in the KEESA.

Change in Control Agreements

We have entered into agreements with certain key corporate executives, including all Named Executive Officers, that provide for contingent benefits upon a change in control. These change in control agreements are intended to provide for continuity of management

upon a completed or threatened change in control. The agreements provide that covered executive officers could be entitled to certain severance or other benefits following a change in control. If, following such a change in control, the executive officer is involuntarily terminated,

56 2022 Proxy Statement

TABLE OF CONTENTS

EXECUTIVE COMPENSATION TABLES

other than for disability or for cause, or if such executive officer terminates his or her employment for conditions that constitute good reason, then the executive officer is entitled to certain severance payments. As previously disclosed, we have adopted a policy of not including automatic single trigger change in control vesting and excise tax gross-ups in new KEESAs.

Under these agreements, “cause” means:

▶

engaging in intentional conduct that causes us demonstrable and serious financial injury;

▶

conviction of a felony; or

▶

continuing willful and unreasonable refusal by an officer to perform his or her duties or responsibilities.

Under these agreements, “good reason” means:

▶

a breach of the agreement by us;

▶

any reduction in an officer’s base salary, percentage of base salary available as cash incentive compensation or bonus opportunity, grant date fair value of equity-based awards or other benefits;

▶

an officer’s removal from, or any failure to reelect or reappoint him or her to serve in, any of the positions held with us on the date of the change in control or any other positions to which he or she is thereafter elected, appointed or assigned, except in the event that such removal or failure to reelect or reappoint relates to our termination of an officer’s employment for cause or by reason of disability;

▶

a good faith determination by an officer that there has been a material adverse change in his or her working conditions or status relative to the most favorable working conditions or status in effect during the 180-day period prior to the change in control, or, to the extent more favorable to him or her, those in effect at any time while employed after the change in control, including a significant change in the nature or scope of his or her authority, powers, functions, duties or responsibilities or a significant reduction in the level of support services, staff, secretarial and other assistance, office space and accoutrements, but in each case excluding for this purpose an isolated, insubstantial and inadvertent event not occurring in bad faith that we remedy within 10 days after receipt of written notice;

▶

relocation of an officer’s principal place of employment to a location more than 50 miles from his or her principal place of employment on the date 180 days prior to the change in control;

▶

imposition of a requirement that an officer travel on business 20% in excess of the average number of days per month he or she was required to travel during the 180-day period prior to the change in control; or

▶

our failure to cause a successor to assume an officer’s agreement.

Under these agreements, a “change in control” is deemed to have occurred if:

▶

any person is or becomes the beneficial owner of securities representing 30% or more of our outstanding ordinary shares or combined voting power;

▶

a majority of the Board changes in a manner that has not been approved by at least two-thirds of the incumbent directors or successor directors nominated by at least two-thirds of the incumbent directors;

▶

we consummate a merger, consolidation or share exchange with any other entity (or the issuance of voting securities in connection with a merger, consolidation or share exchange) which our shareholders have approved and in which our shareholders control less than 50% of combined voting power after the merger, consolidation or share exchange; or

▶

we consummate a plan of complete liquidation or dissolution or an agreement for the sale or disposition of all or substantially all of our assets which our shareholders have approved.

The benefits under the change in control agreements that could be triggered by a change in control and a covered termination in connection with such a change in control include:

▶

upon termination of the executive by us other than for death, disability or cause or by the executive for good reason, after a change in control;

▶

severance payable upon termination in an amount equal to 250% (for Mr. Stauch) or 200% (for all other Named Executive Officers) of annual base salary plus the greatest of the executive’s target bonus for the year of termination, the actual bonus paid during the year prior to the change in control, or the actual bonus paid with respect to the year prior to the change in control;

▶

cash payment to use towards medical, dental and life insurance policies for up to two years;

▶

the cost of an executive search agency not to exceed 10% of the executive’s annual base salary;

Pentair plc 57

TABLE OF CONTENTS

EXECUTIVE COMPENSATION TABLES

▶

the accelerated accrual and vesting of benefits under the SERP (for Mr. Stauch, who has been made a participant in that plan) and under any other nonqualified defined contribution retirement plans; and for those executives who participate in the SERP and have fewer than seven years of participation in the SERP, up to three additional years of service can be credited, up to a maximum of seven years of service;

▶

up to $15,000 in fees and expenses of consultants and legal or accounting advisors; and

▶

all equity-based and cash incentive awards granted prior to the change in control will be subject to the terms of the incentive plan under which they were granted (including accelerated vesting, if provided for in the applicable plan), and all equity-based and cash incentive awards granted on or after the change in control will vest or be earned in full upon such termination.

In the case of each Named Executive Officer, the agreement also requires the executive to devote his or

her best efforts to us or our successor during the three-year or two-year period, to maintain the confidentiality of our information during and following employment and to refrain from competitive activities for a period of one year following termination of employment with us or our successor.

Executive Severance Plan. Under the Executive Severance Plan, all executive officers that are not party to a KEESA are entitled to receive certain severance payments if, following a change in control, the executive officer is involuntarily terminated, other than for death, disability or for cause, or if such executive officer terminates his or her employment for conditions that constitute good reason.

In December 2020, the Compensation Committee approved an amendment to our KEESAs, clarifying that executives are not eligible for both benefits under the KEESA and the Executive Severance Plan in the event that there is a change of control and termination that occurs in a specified time period.

Change in Control and Termination Provisions of Incentive Plans

Change in Control Provisions

The 2020 Plan and the most recent predecessor plan provide that, upon a change in control, unless an agreement between us and the executive provides for a more favorable result to the executive:

▶

all outstanding options, restricted stock and restricted stock units that are not performance awards are immediately vested;

▶

all outstanding performance awards (other than annual incentive awards) are paid in full based on performance at the better of target or trend; and

▶

all outstanding annual incentive awards are paid based on full satisfaction of the performance goals.

Termination Provisions

▶

Retirement. If any of the Named Executive Officers terminates employment in a retirement with at least 10 years of service:

•

If the retirement is prior to age 60: unvested options are forfeited; restricted stock and restricted stock units (that are not performance awards or for which any performance goals have been satisfied) vest pro rata; and performance

awards are paid on a pro rata basis based on actual performance; or

•

If the retirement is after age 60: options continue to vest for 5 years; restricted stock and restricted stock units (that are not performance awards or for which any performance goals have been satisfied) vest in full; and performance awards are paid in full based on actual performance (or on a pro-rated basis for performance awards granted to persons hired or promoted to executive officer after January 1, 2021), in each case as described in more detail below for treatment of awards in the event of a Covered Termination.

▶

Death or Disability. If any of the Named Executive Officers terminates employment as a result of death or disability, options, restricted stock and restricted stock units are immediately vested; and performance awards are paid in full based on actual performance.

▶

Termination Without Cause or for Good Reason. If any of the Named Executive Officers terminates employment in an involuntary termination for a reason other than cause, death or disability (a “Covered Termination”), or in a voluntary termination for good reason, then the employee’s outstanding awards will

58 2022 Proxy Statement

TABLE OF CONTENTS

EXECUTIVE COMPENSATION TABLES

be eligible for continued or accelerated vesting, as described below. For a Named Executive Officer’s termination to be considered a Covered Termination, the officer must execute a general release in a form and manner determined by us. Upon a Covered Termination, awards held by a Board-appointed corporate officer, including such a Named Executive Officer, will be treated as follows:

•

Stock options will remain outstanding, and will continue to vest in accordance with their terms as if the officer had remained in employment, until the earlier of the expiration date of the stock option and the fifth anniversary of the Covered Termination.

•

Restricted stock and restricted stock units (that are not performance awards or for which any performance goals have been satisfied) will vest in full.

•

Performance awards, including restricted stock and restricted stock units that have performance-based vesting, will be paid following the end of the performance period based on achievement of the performance goals established for the awards as if the employee had not experienced a Covered Termination. In December 2020, we revised the treatment of performance awards for awards to persons who are hired as or promoted to executive officer on or after January 1, 2021 to provide that the award will continue to vest based on actual achievement; however, the payout will be prorated for the portion of the performance period when the executive officer was employed.

Under the 2020 Plan, the term “cause” means an act or omission by the officer as is determined by the Plan administrator to constitute cause for termination, including but not limited to any of the following:

▶

a material violation of any company policy;

▶

embezzlement from, or theft of property belonging to, us or any of our affiliates;

▶

conviction of, or plead no contest to, a felony or other crime involving moral turpitude;

▶

willful failure to perform, or gross negligence in the performance of, or failure to perform, assigned duties; or

▶

other intentional misconduct, whether related to employment or otherwise, which has, or has the potential to have, a material adverse effect on our business.

Under the 2020 Plan, the term “good reason” means:

▶

any material breach by us of the terms of any employment agreement;

▶

any reduction in base salary or percentage of base salary available as incentive compensation or bonus opportunity;

▶

a good faith determination by the officer that there has been a material adverse change in the officer’s working conditions or status;

▶

a relocation of the principal place of employment to a location more than 50 miles; or

▶

an increase of 20% or more in travel requirements.

For an event to constitute good reason, we must receive written notice and an opportunity to cure. The definitions under our predecessor equity plan are substantially similar to those above.

Benefits pursuant to these incentive plans are generally applicable to all other participants who meet the requisite criteria as well as to the Named Executive Officers.

As required by the SEC rules, the amounts shown below assume that the applicable termination or other event was effective as of December 31, 2021, and thus are estimates of the amounts that would actually be received. The actual amounts to be received can only be determined in connection with the actual termination or other event.

Retirement

The table below shows the amount of compensation payable to our Named Executive Officers upon a retirement. Mr. Stauch is the only Named Executive

Officer who is eligible for a qualifying retirement (for him, having 10 years of service prior to age 60) as of December 31, 2021.

60 2022 Proxy Statement

TABLE OF CONTENTS

EXECUTIVE COMPENSATION TABLES

The amounts in the table above for termination without cause or for good reason in connection with a change in control assume, to the extent applicable, that:

▶

our ordinary shares were valued at $73.03, the closing market price for our ordinary shares on the last trading day of 2021;

▶

outplacement services fees are $50,000 or 10% of annual base salary, whichever is less;

▶

legal and accounting advisor fees are the maximum possible under the change in control agreements for each executive officer; and

▶

medical, dental and life insurance coverage will continue until two years after a change in control, in each case at the current cost per year for each executive.

The Named Executive Officers’ agreements provide that, if excise taxes would otherwise be imposed in connection with a change in control, the executive’s change in control compensation protections will be either cut back to a level below the level that would trigger the imposition of the excise taxes or paid in full and subjected to the excise taxes, whichever results in the better after-tax result to the executive. Solely for purposes of the calculations in the tables above, we have assumed that the cut back did not apply.

PAY RATIO

As required by Item 402(u) of Regulation S-K, we are providing the following information about the ratio of the median annual total compensation of our employees and the annual total compensation of our Chief Executive Officer.

For the year ended December 31, 2021:

▶

the median of the annual total compensation of all employees of our company (other than our Chief Executive Officer) was reasonably estimated to be $57,343; and

▶

the annual total compensation of our Chief Executive Officer was $9,429,546.

Based on this information, the ratio of the annual total compensation of our Chief Executive Officer to the median of the annual total compensation of all other employees is estimated to be 164 to 1.

To identify our median employee, we began by considering each of the 10,835 individuals employed by us worldwide on October 1, 2021.

We then calculated the target cash compensation (which we define as base salary or wages plus target cash bonus) for such individuals for 2021 to identify our median employee. To calculate the target cash compensation for any employee that we paid in currency other than U.S. Dollars, we applied the applicable foreign currency exchange rate in effect on October 1, 2021 to convert such non-U.S. employee’s target cash compensation into U.S. Dollars.

Once we identified our median employee, we added together all of the elements of such employee’s compensation for 2021 in the same way that we calculate the annual total compensation of our Named Executive Officers in the Summary Compensation Table.

RISK CONSIDERATIONS IN COMPENSATION DECISIONS

The Compensation Committee believes that paying for performance is an important part of its compensation philosophy, but recognizes the risk that incentivizing specific measures of performance may pose to the performance of our company as a whole if personnel were to act in ways designed primarily to maximize their compensation. Therefore, the Compensation Committee conducts an annual assessment of potential risks arising from its compensation programs and policies applicable to all employees. In its December 2021 assessment, the Compensation Committee noted the following considerations, among others:

▶

the balance of our fixed and variable compensation in our executive compensation program;

▶

the balance in our executive compensation program between the achievement of short-term objectives and longer-term value creation;

▶

the mix of compensation forms within our long-term incentive compensation plan;

▶

our use of multiple performance measures under our incentive compensation plans;

▶

metrics tied to segment performance for segment presidents;

PROPOSAL 3

				RATIFY, BY NONBINDING, ADVISORY VOTE, THE APPOINTMENT OF DELOITTE & TOUCHE LLP AS THE INDEPENDENT AUDITOR OF PENTAIR PLC AND TO AUTHORIZE, BY BINDING VOTE, THE AUDIT AND FINANCE COMMITTEE OF THE BOARD OF DIRECTORS TO SET THE AUDITOR'S REMUNERATION
							The Board recommends a vote FOR the ratification of the appointment of Deloitte & Touche LLP as the independent auditor of Pentair plc and the authorization of the Audit and Finance Committee to set the auditor's remuneration

The Audit and Finance Committee has selected and appointed Deloitte & Touche LLP (“D&T”) to audit our financial statements for the fiscal year ending December 31, 2022. The Board, upon the recommendation of the Audit and Finance Committee, is asking our shareholders to ratify, by nonbinding, advisory vote, the appointment and to authorize, by binding vote, the Audit and Finance Committee of the Board of Directors to set the independent auditor’s remuneration. Although approval is not required by our Articles of Association or otherwise, the Board is submitting the appointment of D&T to our shareholders because we value our shareholders’ views on our independent auditor. If the appointment of D&T is not ratified by shareholders, it will be considered as notice to the Board and the Audit and Finance Committee to consider the selection of a different firm. Even if the appointment is ratified, the Audit and Finance Committee in its discretion may select a different independent auditor at any time during the year if it determines that such a change would be in the best interests of our company and our shareholders.

The Audit and Finance Committee is directly responsible for the appointment, compensation, retention and oversight of the independent auditor retained to audit

our financial statements. D&T has been retained as our independent auditor continuously since 1977.

The Audit and Finance Committee is responsible for the audit fee negotiations associated with our retention of D&T. In connection with the mandated rotation of D&T’s lead engagement partner, the Audit and Finance Committee and its Chair are directly involved in the selection of D&T’s new lead engagement partner. The members of the Audit and Finance Committee and the Board believe that the continued retention of D&T to serve as our independent auditor is in our and our shareholders’ best interests.

We expect that one or more representatives of D&T will be present at the Annual General Meeting. Each of these representatives will have the opportunity to make a statement, if he or she desires, and is expected to be available to respond to any questions.

The text of the resolution with respect to Proposal 3 is as follows:

“IT IS RESOLVED, to ratify, on a nonbinding, advisory basis, the appointment of Deloitte & Touche LLP as the independent auditor of Pentair plc and to authorize, in a binding vote, the Audit and Finance Committee to set the auditor’s remuneration.”

EACH OF THE BOARD AND THE AUDIT AND FINANCE COMMITTEE RECOMMENDS A VOTE “FOR” THE RATIFICATION OF THE APPOINTMENT OF DELOITTE & TOUCHE LLP AS THE INDEPENDENT AUDITOR OF PENTAIR PLC AND THE AUTHORIZATION OF THE AUDIT AND FINANCE COMMITTEE TO SET THE AUDITOR’S REMUNERATION.

AUDIT AND FINANCE COMMITTEE PRE-APPROVAL POLICY

The Audit and Finance Committee reviews and approves the external auditor’s engagement and audit plan, including fees, scope, staffing and timing of work. In addition, the Audit and Finance Committee Charter limits the types of non-audit services that may be provided by the independent auditors. Any permitted non-audit services to be performed by the independent auditors must be pre-approved by the Audit and Finance Committee after it is advised of the nature of the engagement and particular services to be provided. The

Audit and Finance Committee pre-approved audit fees and all permitted non-audit services of the independent auditor in 2021. Responsibility for this pre-approval may be delegated to one or more members of the Audit and Finance Committee; all such approvals, however, must be disclosed to the Audit and Finance Committee at its next regularly scheduled meeting. The Audit and Finance Committee may not delegate authority for pre-approvals to management.

FEES PAID TO THE INDEPENDENT AUDITORS

We engaged D&T, Deloitte AG, Deloitte & Touche (Ireland), and the member firms of Deloitte Touche Tohmatsu and their respective affiliates (collectively, the “Deloitte Entities”) to provide various audit, audit-related, tax and other permitted non-audit services to us during

fiscal years 2021 and 2020. The Audit and Finance Committee approved all fees paid to the Deloitte Entities and underlying services provided by the Deloitte Entities. Their fees for these services were as follows (in thousands):

	2021			2020
Audit fees(1)		$	4,775		$	4,949
Audit-related fees(2)			373			174

PROPOSAL 4

				AUTHORIZE THE BOARD OF DIRECTORS TO ALLOT NEW SHARES UNDER IRISH LAW
							The Board recommends a vote FOR authorization of the Board of Directors to allot new shares under Irish law

Under Irish law, directors of an Irish public limited company must have authority from its shareholders to allot (or issue) any shares, including shares that are part of our company’s authorized but unissued share capital. The Board’s current authority to issue up to 33% of the Company’s issued ordinary share capital was approved by the shareholders at the 2021 Annual General Meeting and will expire on November 4, 2022. This authority is fundamental to our business and enables us to issue shares, including, if applicable, in connection with funding acquisitions and raising capital.

We are presenting this Proposal 4 to renew the Board’s authority to issue up to a maximum of 33% of a company’s issued ordinary share capital as at March 18, 2022 (the latest practicable date before this Proxy Statement) and for such authority to expire 18 months from the passing of this resolution, unless otherwise varied, revoked or renewed.

Granting the Board this authority is a routine matter for public limited companies incorporated in Ireland and is consistent with Irish market practice. We are not asking you to approve an increase in our authorized share capital or to approve a specific issuance of shares. Instead, approval of this proposal will only grant the Board of Directors the authority to allot shares upon the terms below. In addition, we note that, because we are

a NYSE-listed company, our shareholders continue to benefit from the protections afforded to them under the rules and regulations of the NYSE and SEC, including those rules that limit our ability to issue shares in specified circumstances.

The text of the resolution in respect of Proposal 4 is as follows:

“IT IS RESOLVED, that, the Board of Directors be and is generally and unconditionally authorized with effect from the passing of this resolution to exercise all powers of the Company to allot relevant securities (as defined in Section 1021 of the Companies Act 2014) in an amount up to an aggregate nominal amount of $545,819 (equivalent to 54,581,892 ordinary shares), being equivalent to approximately 33% of the aggregate nominal value of the issued ordinary share capital of the Company as of March 18, 2022 (the latest practicable date before this Proxy Statement), and the authority conferred by this resolution shall expire eighteen months from the passing of this resolution, unless previously renewed, varied or revoked; provided that the Company may make an offer or agreement before the expiry of this authority, which would or might require any such securities to be allotted after this authority has expired, and in that case, the Directors may allot relevant securities in pursuance of any such offer or agreement as if the authority conferred hereby had not expired.”

THE BOARD RECOMMENDS A VOTE “FOR” AUTHORIZATION OF THE BOARD OF DIRECTORS TO ALLOT NEW SHARES UNDER IRISH LAW.

PROPOSAL 5

				AUTHORIZE THE BOARD OF DIRECTORS TO OPT-OUT OF STATUTORY PREEMPTION RIGHTS UNDER IRISH LAW
							The Board recommends a vote FOR authorization of the Board of Directors to opt-out of statutory preemption rights under Irish law

Under Irish law, unless otherwise authorized, certain statutory preemption rights apply automatically in favor of shareholders where shares are to be issued for cash. Under the statutory preemption rights, shares issued for cash must be offered to existing shareholders of our company on a pro rata basis before the shares can be issued to any new shareholders. The Board’s current authority to opt-out of these statutory preemption rights was approved by the shareholders at the 2021 Annual General Meeting and will expire on November 4, 2022. The statutory preemption rights do not apply where shares are issued for non-cash consideration (such as in a stock-for-stock acquisition) and do not apply to the issue of non-equity shares (that is, shares that have the right to participate only up to a specified amount in any income or capital distribution) or where shares are issued pursuant to an employee option or similar equity plan.

We are presenting this Proposal 5 to renew the Board’s authority to opt-out of the statutory preemption rights provision in the event of (1) the issuance of shares in connection with any rights issue and (2) the issuance of shares for cash, if the issuance is limited to up to 5% of a company’s issued ordinary share capital as at March 18, 2022 (the latest practicable date before this Proxy Statement) (with the possibility of issuing up to an additional 5% of the company’s issued ordinary share capital as at March 18, 2022 provided the company uses it only in connection with an acquisition or specified capital investment which is announced contemporaneously with the issuance, or which has taken place in the preceding 6-month period and is disclosed in the announcement of the issue) bringing the total acceptable limit to 10% of the company’s issued ordinary share capital as at March 18, 2022 and, provided further that, in each case, such authority will be limited to a period expiring 18 months from the passing of this resolution, unless otherwise varied, renewed or revoked.

Granting the Board this authority is a routine matter for public limited companies incorporated in Ireland and is consistent with Irish customary practice. Similar to the authorization sought for Proposal 4, this authority is fundamental to our business and, if applicable, will facilitate our ability to fund acquisitions and otherwise

raise capital. We are not asking you to approve an increase in our authorized share capital. Instead, approval of this proposal will only grant the Board the authority to issue shares upon the terms below. Without this authorization, in each case where we issue shares for cash, we would first have to offer those shares on the same or more favorable terms to all of our existing shareholders. This requirement could cause delays in the completion of acquisitions and capital raising for our business. Furthermore, we note that this authorization is required as a matter of Irish law and is not otherwise required for U.S. companies listed on the NYSE. In addition, under Irish law, the Board will only be authorized to opt-out of preemption rights if it is authorized to issue shares, which authority is being sought in Proposal 4.

The text of the resolution with respect to Proposal 5 is as follows:

“IT IS RESOLVED, as a special resolution, that, subject to the passing of the resolution in respect of Proposal 4 as set out above and with effect from the passing of this resolution, the directors be and are hereby empowered pursuant to Section 1023 of the Companies Act 2014 to allot equity securities (as defined in Section 1023 of that Act) for cash, pursuant to the authority conferred by Proposal 4 as if sub-section (1) of Section 1022 of that Act did not apply to any such allotment, provided that this power shall be limited to:

(a)

the allotment of equity securities in connection with a rights issue or other preemptive issue in favor of the holders of ordinary shares (including rights to subscribe for, or convert into, ordinary shares) where the equity securities respectively attributable to the interests of such holders are proportional (as nearly as may be) to the respective numbers of ordinary shares held by them (but subject to such exclusions or other arrangements as the Board may deem necessary or expedient to deal with fractional entitlements that would otherwise arise, or with legal or practical problems under the laws of, or the requirements of any recognized regulatory body or any stock exchange in any territory, or otherwise); and

Pentair plc 67

TABLE OF CONTENTS

PROPOSAL 5

(b)

the allotment (other than pursuant to sub-paragraph (a) above) of equity securities up to an aggregate nominal value of $165,400 (equivalent to 16,539,967 ordinary shares) (being equivalent to approximately 10% of the aggregate nominal value of the issued ordinary share capital of the Company as of March 18, 2022 (the latest practicable date before this Proxy Statement)), provided that any amount above $82,700 (equivalent to 8,269,984 ordinary shares) (being equivalent to approximately 5% of the aggregate nominal value of the issued ordinary share capital of the Company as of March 18, 2022)

is to be used only for the purpose of an acquisition or a specific capital investment, and the authority conferred by this resolution shall expire 18 months from the passing of this resolution, unless previously renewed, varied or revoked; provided that the Company may make an offer or agreement before the expiry of this authority, which would or might require any such securities to be allotted after this authority has expired, and in that case, the Board may allot equity securities in pursuance of any such offer or agreement as if the authority conferred hereby had not expired.”

PROPOSAL 6

				AUTHORIZE THE PRICE RANGE AT WHICH PENTAIR PLC CAN RE-ALLOT SHARES IT HOLDS AS TREASURY SHARES UNDER IRISH LAW
							The Board recommends a vote FOR the authorization of the price range at which Pentair plc can re-allot shares it holds as treasury shares under Irish law

Our historical open-market share repurchases (whether effected as redemptions or otherwise) and other share buyback activities result in ordinary shares being acquired and held by us as treasury shares. We may re-allot treasury shares that we acquire through our various share buyback activities in connection with our employee compensation programs or otherwise.

Under Irish law, our shareholders must authorize the price range at which we may re-allot any shares held in treasury. In this proposal, that price range is expressed as a minimum and maximum percentage of the prevailing market price (as defined below). The Company’s current authorization was granted by the shareholders at the 2021 Annual General Meeting and will expire on November 4, 2022.

The authority being sought from shareholders provides that the minimum and maximum prices at which an ordinary share held in treasury may be re-allotted are 95% (or nominal value where the re-allotment of treasury shares is required to satisfy an obligation under any employee or director share or option plan operated by Pentair plc) and 120%, respectively, of the average closing price per ordinary share, as reported on the New York Stock Exchange, for the 30 trading days immediately preceding the proposed date of re-allotment. Any re-allotment of treasury shares will be at price levels that the Board considers in the best interests of our shareholders. Under Irish law, this authorization will expire after eighteen months unless renewed. Accordingly, we expect to propose renewal of this authorization at subsequent Annual General Meetings.

The resolution with respect to Proposal 6 is a special resolution. The text of the resolution with respect to Proposal 6 is as follows:

“IT IS RESOLVED, as a special resolution, that for the purposes of Section 1078 of the Companies Act 2014, the re-allotment price range at which any treasury shares (as defined by Section 106 of the Companies Act 2014) for the time being held by Pentair plc may be re-allotted off-market shall be as follows:

the maximum price at which a treasury share may be re-allotted off-market shall be an amount equal to 120% of the “market price.”

the minimum price at which a treasury share may be re-allotted off-market shall be the nominal value of the share where such a share is required to satisfy an obligation under any employee or director share or option plan operated by Pentair plc or, in all other cases, not less than 95% of the “market price.”

for the purposes of this resolution, the “market price” shall mean the average closing price per ordinary share of Pentair plc, as reported on the New York Stock Exchange, for the 30 trading days immediately preceding the day on which the relevant share is re-allotted.

FURTHER RESOLVED, that this authority to re-allot treasury shares shall expire on the date 18 months from the date of the passing of this resolution unless previously varied, revoked or renewed in accordance with the provisions of Sections 109 and/or 1078 (as applicable) of the Companies Act 2014 (and/or any corresponding provision of any amended or replacement legislation) and is without prejudice or limitation to any other authority of the Company to re-allot treasury shares on-market.”

THE BOARD RECOMMENDS A VOTE “FOR” THE AUTHORIZATION OF THE PRICE RANGE AT WHICH PENTAIR PLC CAN RE-ALLOT SHARES IT HOLDS AS TREASURY SHARES UNDER IRISH LAW.

TABLE OF CONTENTS

QUESTIONS AND ANSWERS ABOUT THE ANNUAL GENERAL MEETING AND VOTING

Why did I receive these proxy materials?

We are providing these proxy materials to you because our Board of Directors is soliciting proxies for use at our Annual General Meeting of Shareholders to be held on May 17, 2022. We either (i) mailed you a Notice of Internet Availability of Proxy Materials on or before April 1, 2022 notifying each shareholder entitled to vote at the Annual General Meeting how to vote and how to electronically access a copy of this Proxy Statement and our Annual Report on Form 10-K for the fiscal year ended December 31, 2021 or (ii) mailed you a printed copy of such proxy materials and a proxy card in paper format. You received these proxy materials because you were a shareholder of record as of the close of business on March 18, 2022.

If you received a Notice of Internet Availability of Proxy Materials and would like to receive a printed copy of our proxy materials, including a proxy card in paper format on which you may submit your vote by mail, you should follow the instructions for requesting such proxy materials in the Notice of Internet Availability of Proxy Materials.

This Proxy Statement, our Annual Report on Form 10-K for the fiscal year ended December 31, 2021 and our Irish Statutory Financial Statements and directors’ and auditors’ reports are available online at www.proxyvote.com.

What is a proxy?

A proxy is your legal designation of another person (the “proxy”) to vote on your behalf. By voting your proxy, you are giving the persons named on the proxy card the authority to vote your shares in the manner you indicate on your proxy card. You may vote your proxy by telephone or over the Internet as directed in the Notice of Internet Availability of Proxy Materials or, if you have requested or received a proxy card, by signing and dating the proxy card and submitting it by mail.

What is the difference between a shareholder of record and a beneficial owner?

If your shares are registered directly in your name with Computershare Trust Company, N.A., our transfer agent, you are a “shareholder of record.” If your shares are held in a stock brokerage account or by a bank or other custodian or nominee, you are considered the beneficial

owner of shares held in “street name.” As a beneficial owner, you have the right to direct your broker, bank or other custodian or nominee on how to vote your shares.

Who is entitled to vote at the Annual General Meeting and how many votes do I have?

The Board has set the close of business on March 18, 2022 (Eastern Standard Time) as the record date for the Annual General Meeting. At the close of business on the record date, we had 165,399,674 ordinary shares issued and outstanding and entitled to vote. All shareholders of record at the close of business on the record date are entitled to vote on the matters set forth in this Proxy Statement and any other matter properly presented at the Annual General Meeting. Beneficial owners whose banks, brokers or other custodians or nominees are shareholders registered in our share register with respect to the beneficial owners’ shares at the close of business on the record date are entitled to vote on the matters set forth in this Proxy Statement and any other matter properly presented at the Annual General Meeting. Each ordinary share is entitled to one vote on each matter properly brought before the Annual General Meeting.

How do I vote if I am a shareholder of record?

If you are a shareholder of record of ordinary shares, you can vote in the following ways:

▶

By Internet: You can vote over the Internet at www.proxyvote.com. For more information, follow the instructions in the Notice of Internet Availability of Proxy Materials or on the proxy card.

▶

By Telephone: You can vote by telephone from the United States or Canada by calling the telephone number in the Notice of Internet Availability of Proxy Materials or on the proxy card.

▶

By Mail: You can vote by mail by marking, signing and dating your proxy card or voting instruction form and returning it in the postage-paid envelope, the results of which will be forwarded to Pentair plc’s registered address in Ireland electronically. For more information, follow the instructions in the Notice of Internet Availability of Proxy Materials or on the proxy card.

TABLE OF CONTENTS

QUESTIONS AND ANSWERS ABOUT THE ANNUAL GENERAL MEETING AND VOTING

▶

At the Annual General Meeting: If you plan to attend the Annual General Meeting and wish to vote your ordinary shares in person, we will give you a ballot at the meeting.

How do I vote if I am a beneficial owner?

If you are a beneficial owner of ordinary shares, you can vote in the following ways:

▶

General: You can vote by following the materials and instructions provided by your bank, broker or other custodian or nominee.

▶

At the Annual General Meeting: If you plan to attend the Annual General Meeting and wish to vote your ordinary shares in person, then you must obtain a legal proxy, executed in your favor, from the shareholder of record of your shares (i.e., your broker, bank or other custodian or nominee) and bring it to the Annual General Meeting.

What is the deadline to vote my shares if I do not vote in person at the Annual General Meeting?

If you are a shareholder of record, you may vote by Internet or by telephone until 4:59 a.m. (British Summer Time) on May 16, 2022 (11:59 p.m. Eastern Daylight Time on May 15, 2022). If you are a shareholder of record and submit a proxy card, the proxy card must be received at the address stated on the proxy card by 4:59 a.m. (British Summer Time) on May 16, 2022 (11:59 p.m. Eastern Daylight Time on May 15, 2022). If you are a beneficial owner, please follow the voting instructions provided by your bank, broker or other custodian or nominee.

How do I attend the Annual General Meeting?

All shareholders of record as of the close of business on the record date are invited to attend and vote at the Annual General Meeting. For admission to the Annual General Meeting, shareholders should bring a form of photo identification to the shareholders check-in area at the meeting, where their ownership will be verified. Those who beneficially own shares should also bring account statements or letters from their banks, brokers or other custodians or nominees confirming that they own our ordinary shares as of March 18, 2022 (see above for further information if you also intend to vote at the Annual General Meeting). Registration will begin at 7:30 a.m. (British Summer Time) and the Annual General Meeting will begin at 8:00 a.m. (British Summer Time) on May 17, 2022.

Shareholders in Ireland may participate in the Annual General Meeting by audio link at the offices of Arthur Cox LLP at Ten Earlsfort Terrace, Dublin 2, D02 T380, Ireland at 8:00 a.m. (Irish Standard Time), and the requirements for admission to the Annual General Meeting, as set out above, apply.

What constitutes a quorum for the Annual General Meeting?

Our Articles of Association provide that all resolutions made at a shareholders’ meeting require the presence, in person or by proxy, of a majority of all shares entitled to vote. Abstentions and broker non-votes will be regarded as present for purposes of establishing the quorum.

May I change or revoke my proxy?

If you are a shareholder of record and have already voted, you may change or revoke your proxy before it is exercised at the Annual General Meeting in the following ways:

▶

By voting by Internet or telephone at a date later than your previous vote but prior to the voting deadline (which is 4:59 a.m. (British Summer Time) on May 16, 2022 (11:59 p.m. Eastern Daylight Time on May 15, 2022);

▶

By mailing a proxy card (in the form mailed to our or in the form set out in section 184 of the Irish Companies Act 2014) that is properly signed and dated later than your previous vote and that is received by us prior to the voting deadline (which is 4:59 a.m. (British Summer Time) on May 16, 2022 (11:59 p.m. Eastern Daylight Time on May 15, 2022); or

▶

By attending the Annual General Meeting and voting in person, although attendance at the Annual General Meeting will not, by itself, revoke a proxy.

If you are a beneficial owner, you must contact the record holder of your shares to revoke a previously authorized proxy or voting instructions.

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

A broker non-vote occurs when a broker holding shares for a beneficial owner does not vote on a particular agenda item because the broker does not have discretionary voting power for that particular item and has not received instructions from the beneficial owner. Although brokers have discretionary power to vote your shares with respect to “routine” matters, they do not have discretionary power to vote your shares on “non-routine” matters pursuant to NYSE rules. If you do not

QUESTIONS AND ANSWERS ABOUT THE ANNUAL GENERAL MEETING AND VOTING

provide voting instructions for proposals considered “non-routine,” a “broker non-vote” occurs. The chart below summarizes which proposals we believe are routine and non-routine under the NYSE rules and therefore whether brokers have discretion to vote. Ordinary shares owned by shareholders electing to abstain from voting on any of the proposals will have no effect on any of the proposals.

How will my shares be voted if I do not specify how they should be voted?

If you submit a proxy to the company-designated proxy holders and do not provide specific voting instructions, you instruct the company-designated proxy holders to vote your shares in accordance with the recommendations of the Board as set forth in the chart below.

If your shares are held in the Pentair, Inc. Retirement Savings and Stock Incentive Plan or the Pentair, Inc. Non-Qualified Deferred Compensation Plan and you

either (1) submit a proxy but do not provide specific voting instructions or (2) do not submit a proxy, then your shares will not be voted.

How will voting on any other business be conducted?

Other than matters incidental to the conduct of the Annual General Meeting and those set forth in this Proxy Statement, we do not know of any business or proposals to be considered at the Annual General Meeting. If any other business is proposed and properly presented at the Annual General Meeting, you instruct the company-designated proxy holders, in the absence of other specific instructions or the appointment of other proxy holders, to vote your shares in accordance with the recommendations of the Board.

The following chart describes the proposals to be considered at the meeting, the vote required to elect directors and to adopt each other proposal, and the manner in which votes will be counted:

We have engaged Morrow Sodali LLC to assist us in the solicitation of proxies at a cost to us of $10,000, plus out-of-pocket expenses. We have requested that banks, brokers and other custodians and nominees who hold ordinary shares on behalf of beneficial owners forward soliciting materials to those beneficial owners. Upon request, we will reimburse banks, brokers and other custodians and nominees for reasonable expenses incurred by them in forwarding these soliciting materials to beneficial owners of our ordinary shares.

74 2022 Proxy Statement

TABLE OF CONTENTS

QUESTIONS AND ANSWERS ABOUT THE ANNUAL GENERAL MEETING AND VOTING

Why did I receive a notice in the mail regarding the Internet availability of the proxy materials instead of a paper copy of the proxy materials?

As explained in more detail below, we are using the “notice and access” system adopted by the SEC relating to the delivery of our proxy materials over the Internet. As a result, we mailed to our shareholders of record a notice about the Internet availability of the proxy materials instead of a paper copy of the proxy materials. Shareholders who received the notice will have the ability to access the proxy materials over the Internet and to request a paper copy of the proxy materials by mail, e-mail or telephone. Instructions on how to access the proxy materials over the Internet or to request a paper copy may be found on the notice. In addition, the notice contains instructions on how shareholders may request proxy materials in printed form by mail or electronically by e-mail on an ongoing basis. The Notice of Internet Availability of Proxy Materials also serves as a Notice of Meeting.

What are the “notice and access” rules and how do they affect the delivery of the proxy materials?

The SEC’s notice and access rules allow us to deliver proxy materials to our shareholders by posting the materials on an Internet website, notifying shareholders

of the availability of the proxy materials on the Internet, and sending paper copies of proxy materials upon shareholder request. We believe that the notice and access rules allow us to use Internet technology that many shareholders prefer, continue to provide our shareholders with the information that they need, and, at the same time, ensure more prompt delivery of the proxy materials. The notice and access rules also lower our cost of printing and delivering the proxy materials and minimize the environmental impact of printing paper copies.

Why did I receive more than one Notice of Internet Availability of Proxy Materials or proxy card?

You may have received multiple Notices of Internet Availability of Proxy Materials or proxy cards if you hold your shares in different ways or accounts (for example, 401(k) accounts, joint tenancy, trusts, custodial accounts) or in multiple accounts. If you are the beneficial owner of shares held in “street name,” you will receive your voting information from your bank, broker or other custodian or nominee, and you will vote as indicated in the materials you receive from your bank, broker or other custodian or nominee. You should vote your proxy for each separate account you have.

Any such proposal must meet the requirements set forth in the rules and regulations of the SEC, including Rule 14a-8, for such proposals to be eligible for inclusion in our Proxy Statement and form of proxy for our 2023 Annual General Meeting.

Nomination of Directors Pursuant to Proxy Access Provisions:

Eligible shareholders may under certain circumstances be able to nominate and include in our proxy materials a specified number of candidates for election as directors under the proxy access provisions of our Articles of Association.

IRISH DISCLOSURE OF SHAREHOLDER INTERESTS

Under the Irish Companies Act 2014, our shareholders must notify us if, as a result of a transaction, the shareholder will become interested in 3% or more of our shares, or if as a result of a transaction, a shareholder who was interested in more than 3% of our shares ceases to be so interested. Where a shareholder is interested in more than 3% of our shares, the shareholder must notify us of any alteration of his or her interest that brings his or her total holding through the nearest whole percentage number, whether an increase or a reduction. The relevant percentage figure is calculated by reference to the aggregate nominal value of the shares in which the shareholder is interested as a proportion of the entire nominal value of our issued share capital (or

any such class of share capital in issue), and disclosable interests in our shares include any interests in our shares of any kind whatsoever. Where the percentage level of the shareholder’s interest does not amount to a whole percentage this figure may be rounded down to the next whole number. We must be notified within five business days of the transaction or alteration of the shareholder’s interests that gave rise to the notification requirement. If a shareholder fails to comply with these notification requirements, the shareholder’s rights in respect of any of our ordinary shares it holds will not be enforceable, either directly or indirectly. However, such person may apply to the court to have the rights attaching to such shares reinstated.

2021 ANNUAL REPORT ON FORM 10-K

Any shareholder wishing to review, without charge, a copy of our 2021 Annual Report on Form 10-K (without exhibits) filed with the SEC should write to us at our principal executive offices at Pentair plc, Regal House, 70 London Road, Twickenham, London, TW1 3QS,United Kingdom, Attention: Corporate Secretary.
