Plexus Corp. (“Plexus” or “the Company”) will hold its annual meeting of shareholders virtually on February 11, 2025, at 7:30 a.m. CST. Shareholders may participate in the virtual annual meeting by logging in at the following link and providing the control number found in the Notice of Internet Availability of Proxy Materials: www.virtualshareholdermeeting.com/PLXS2025.

On or about December 13, 2024, we mailed to shareholders a Notice of Internet Availability of Proxy Materials (“Notice”) containing instructions on how to access our proxy materials, including our proxy statement and annual report, and how to vote via the internet. Shareholders will not receive printed copies of the proxy materials unless requested via the procedures described in the Notice. To assure timely delivery of printed copies of the proxy materials before the virtual annual meeting, shareholders need to request a copy no later than January 21, 2025.

Shareholders of record at the close of business on December 6, 2024 (the “Record Date”) are entitled to participate and vote at the virtual annual meeting. As of the Record Date, Plexus had 27,087,943 shares of common stock outstanding. If you are a shareholder of record as of the Record Date, then you may vote either at the virtual annual meeting or in advance of the meeting by authorizing—by internet, telephone or mail—the persons named as proxies on the proxy card, Dean A. Foate, Todd P. Kelsey, Patrick J. Jermain and Angelo M. Ninivaggi, to vote your shares in accordance with your directions. We encourage you to vote as soon as possible, even if you are planning to attend the annual meeting by virtual presence online, so that the vote count will not be delayed.

If for any reason you desire to revoke your proxy, then you may do so at any time before it is voted, either by written notice filed with the Secretary, or Acting Secretary, of the meeting. Questions may be asked during the virtual meeting by submitting such questions in writing via the online platform.

For those investors whose shares are held by a broker or other nominee, you must complete and return the voting instruction form provided by your broker, bank or nominee to provide instruction on how to cast your vote. In the absence of your voting instructions, brokers or other nominees may or may not be able to vote your shares at their discretion depending upon the particular proposal. For example, brokers may not vote your shares at their discretion in the election of directors; therefore, you must vote your shares if you want them to be counted in the election of directors. In addition, your broker is not permitted to vote your shares at its discretion regarding matters related to executive compensation, including the advisory vote to approve named executive officer (“NEO”) compensation. If a broker or other nominee holds your shares and you wish to change your proxy prior to the voting thereof, please contact the broker or other nominee.

Shareholders who own shares as part of Plexus’ 401(k) Retirement Plan (the “401(k) Plan”) will receive a separate means for voting the shares held in each account. Shares held by the 401(k) Plan for which participant designations are received will be voted in accordance with those designations. Those shares for which designations are not received will be voted proportionally based upon the shares for which voting directions have been received from participants in the 401(k) Plan.

The Secretary must receive a shareholder proposal no later than August 15, 2025 for the proposal to be considered for inclusion in our proxy materials for the 2026 annual meeting pursuant to Rule 14a-8 of the rules of the Securities and Exchange Commission. The 2026 annual meeting of shareholders is tentatively scheduled for February 18, 2026. To bring a proposal or nomination before the 2026 annual meeting, you must comply with our bylaws, which require written notice to the Secretary between October 4, 2025 and October 29, 2025. The purpose of this requirement is to assure adequate notice of, and information regarding, any such matter as to which shareholder action may be sought. If we receive your notice after October 29, 2025, then your proposal or nomination would be untimely and it will not be presented to shareholders for action at the 2026 annual meeting of shareholders. To comply with the universal proxy rules, shareholders who intend to solicit proxies in support of director nominees other than the Company’s nominees must provide the additional information required by Rule 14a-19(b) under the Securities Exchange Act of 1934. Such additional information must be received by the Secretary by no later than October 29, 2025. In addition, your proposal or nomination must comply with the procedural provisions of our bylaws. If you do not comply with these procedural provisions, your proposal or nomination can be excluded. Should the board nevertheless choose to present your proposal, the named proxies will be able to vote on the proposal using their best judgment.

To conduct the virtual annual meeting, more than 50% of Plexus’ outstanding shares entitled to vote must be present at the virtual annual meeting or by duly authorized proxy. This is referred to as a “quorum.” Abstentions and shares that are the subject of broker non-votes will be counted for the purpose of determining whether a quorum exists. Shares represented at a meeting for any purpose are counted in the quorum for all matters to be considered at the meeting. Each outstanding share of common stock is entitled to one vote on each matter presented.

If you own shares as a registered holder and you do not vote, then your shares will not be represented at the meeting and will not count toward the quorum requirement. If a quorum is obtained, then the shares that you have not voted will not affect whether a proposal is approved or rejected. If you are a shareholder whose shares are not registered in your name and you do not vote, then your bank, broker or other holder of record may still represent your shares at the meeting for purposes of obtaining a quorum.

Assuming a quorum is present, directors are elected by a plurality of the votes cast at the meeting or by proxy by the holders of Plexus common stock entitled to vote in the election at the meeting. “Plurality” means that the individuals who receive the highest number of votes are elected as directors, up to the maximum number of directors to be chosen at the meeting. Therefore, any shares that are not voted, whether by withheld authority, broker non-vote or otherwise, have no effect in the election of directors except to the extent that the failure to vote for any individual results in another individual receiving a relatively larger number of votes.

Our bylaws provide that if any nominee for director does not receive, in an uncontested election, a majority of the votes cast for his or her election, the board will determine whether to accept the individual’s irrevocable, contingent resignation from the board (which must be submitted to, or on file with, the Company in order for that person to be nominated for board service).

Assuming a quorum is present, approval of the non-binding advisory vote regarding the compensation of our named executive officers will be determined by a majority of votes cast on such matter. In addition, ratification of PricewaterhouseCoopers LLP as our independent auditors for 2025 must be approved by a majority of votes cast on each such matter, assuming a quorum is present. Abstentions and broker non-votes will not affect these votes, except insofar as they reduce the number of shares that are voted.

Broadridge Financial Solutions, Inc. will use an automated system to tabulate the votes, and its representative(s) will also serve as the election inspector(s).

The following table presents certain information as of the Record Date (December 6, 2024), regarding the beneficial ownership of Plexus common stock by each current director or nominee for director, each named executive officer appearing in the “Summary Compensation Table” included in “Executive Compensation” herein and all directors or nominees for director and current executive officers as a group. The following table also presents each known 5%-or-greater beneficial owner of Plexus common stock as of the date of their most-recently filed Schedule 13G/A or 13G report, as applicable. The specified individuals and entities have sole voting and sole dispositive powers as to all shares except as otherwise indicated.

Plexus currently has 10 directors, listed below, as of the Record Date. Plexus’ bylaws currently authorize up to 12 directors, as determined by the board. The Plexus board may elect directors to fill empty seats, including those created by an expansion, between meetings of shareholders.

The individuals who are nominated as directors, and for whom proxies will be voted unless a shareholder specifies otherwise, are named below. If any of the nominees should decline or be unable to act as a director, which is unforeseen, the proxies will be voted with discretionary authority for a substitute nominee designated by the board of directors. Each of the director nominees named below was elected at the 2024 annual meeting.

 

The composition of the board of directors is reviewed annually to ensure that an appropriate mix of skills, experiences and backgrounds is represented; the membership mix of the board may also be changed as necessary to meet business needs.

The board nominees offer a diverse range of skills and experience in relevant areas, as set forth in the matrix below. Unless otherwise noted, all directors have been employed in their principal occupation listed for the past five years or more.

Plexus believes that it needs to attract and retain talented, focused and motivated leadership to develop and execute the Company’s long-term strategy and to deliver shareholder value. For Plexus, the concept of leadership is not limited to leadership within the Company; leadership also includes the individuals who serve on Plexus’ board of directors. The Company believes it is important for its board to be comprised of individuals with diverse backgrounds, skills and experiences. All board members are expected to meet Plexus’ board member selection criteria, which are listed below:

In addition to the general criteria for each board member, the diversity of the board should endeavor to include those board qualifications, attributes, skills and experience set forth in the “Board Qualifications, Attributes, Skills and Experience” above. In the selection of board members, the Governance & Sustainability Committee (“Governance Committee”) also considers the demographic diversity among members in identifying areas that could be augmented by new members.

We are committed to governance structures and practices that drive shareholder value and protect important shareholder rights, which are regularly reviewed and include the following:

Our independent directors have the opportunity to meet in executive session, without management present, as part of each regular board and committee meeting. Mr. Schrock, the board’s Lead Director, presides at board executive sessions. Plexus generally holds a board meeting coincident with the annual meeting of shareholders to minimize director travel obligations and facilitate their attendance at the shareholders’ meeting. Board members are expected to attend the Company’s annual meeting of shareholders each year, either in person or remotely if a virtual shareholder meeting is held.

As a matter of good corporate governance, we believe that the board of directors should provide a strong voice in the governance of our company. Therefore, under our corporate governance policies and in accordance with Nasdaq Global Select Market rules, at least a majority of our directors must be “independent directors.”

When the board of directors makes its determinations regarding which directors are independent, it first considers and follows the Nasdaq Global Select Market rules. The board also reviews other transactions and relationships, if any, involving Plexus and its directors or their family members or related parties; see “Certain Transactions” herein for a discussion of our policy regarding such transactions. Plexus expects its directors to disclose any transaction, whether direct or indirect, such as through an immediate family member or an affiliated business entity, involving Plexus and the director; Plexus also surveys directors periodically to confirm this information. Plexus does not use any dollar amount to screen transactions that should be reported to the Company. The board reviews the information submitted by its directors for its separate determination of materiality and compliance with Nasdaq and other standards when it determines independence.

Based on the applicable standards and the board’s review and consideration, the board of directors has determined that, of the director nominees, Dr. Eisenhart and Mses. Rapp and Wuamett, as well as Messrs. Jueckstock, Martinez, Quadracci, Rooke and Schrock, are each “independent” under applicable Nasdaq rules and guidelines. In reaching its determinations regarding the independence of Ms. Wuamett and Ms. Rapp, the board considered that Ms. Wuamett serves as an executive officer of NXP Semiconductors N.V., which is a supplier to Plexus, and that Ms. Rapp was an executive officer of National Instruments Corp. and is a director of Microchip Technology, Inc., both of which are also suppliers to Plexus. The board determined that these relationships did not affect the independence of Mses. Wuamett or Rapp. Mr. Foate, our Non-Executive Chair and former Chief Executive Officer (“CEO”), and Mr. Kelsey, our current President and CEO, are not considered to be “independent” under applicable Nasdaq rules.

Mr. Foate has served as Chair of the Board since 2013. Pursuant to a retirement and transition agreement (the “Transition Agreement”), which is described in “Directors’ Compensation” below, Mr. Foate began serving as Non-Executive Chair (which is not an executive officer position) in fiscal year 2018.

Mr. Foate serves as the Chair of the Board primarily due to his in-depth knowledge of the Company and EMS industry, keen understanding of the Company’s operations and strategies, and proven leadership of, as well as vision for, Plexus, all of which position him to provide strong and effective leadership of the board. Mr. Foate joined Plexus in 1984 and served as CEO from 2002 until his retirement in 2016. In addition to his experience and long service with Plexus, the board currently believes that Mr. Foate is in the best position as Chair to lead board discussions regarding the Company’s business and strategy, and to help the board respond quickly and effectively to any challenges faced by the Company.

While currently the roles of Chair and CEO are held by Mr. Foate and Mr. Kelsey, respectively, the board does not have a policy that requires the separation of these roles and believes the Company should adopt the board leadership structure that best serves its needs at any particular time. Pursuant to the Company’s Corporate Governance Guidelines, since Mr. Foate is not an independent director, the independent directors, meeting in executive session, elected a Lead Director from among the independent directors.

The Company believes that the designation of an independent Lead Director, whose duties are described below, provides essentially the same benefits as having an independent chair in terms of oversight, access and an independent voice with significant input into corporate governance. Mr. Schrock currently serves as the board’s Lead Director.

All of the members of the Audit Committee are “independent” of Plexus under SEC and Nasdaq rules. The board has determined that Mr. Jueckstock and Ms. Rapp are “audit committee financial experts” based on a review of their educational backgrounds and business experiences. All members of the Audit Committee are “financially literate” and meet the other SEC and Nasdaq requirements for Audit Committee membership.

All of the members of the Compensation Committee are “independent” under SEC and Nasdaq rules. The Compensation Committee may, in its sole discretion, retain or obtain the advice of compensation consultants, legal counsel or other advisers. The Compensation Committee is directly responsible for the appointment, termination, compensation and oversight of the work of any compensation consultant, and considers the independence of any such consultant prior to retention.

All of the members of the Governance Committee are “independent” under SEC and Nasdaq rules.

The Governance Committee engages in a continuous process of identifying and assessing potential director candidates in light of the board’s collective set of skills and the future needs of the Company. In addition to the board member selection criteria listed above, the Governance Committee considers the diversity of backgrounds, skills and experiences among board members in identifying areas that could be augmented by new members. To help assure that directors have the time to devote to their duties, Plexus directors may not serve on the boards of more than three additional public companies. The Governance Committee may utilize a director search firm to identify candidates, but, if so, it evaluates those individuals on its own; the Governance Committee would also consider candidates suggested by outside directors, management and/or shareholders. If a qualified individual expresses a serious interest and there is a position available, the Governance Committee would review that person’s background and experience to determine whether that individual may be an appropriate addition to the board, and, if appropriate, would meet with the individual. A decision would then be made whether to nominate that person to the board. The Governance Committee’s policy is not to evaluate proposed nominees differently depending upon who has proposed the potential nominee. In addition, the Governance Committee is committed to prioritizing the inclusion of racially and ethnically diverse candidates in the pool from which director nominees are selected.

If a shareholder wishes to identify someone as a director for the Governance Committee’s consideration in the manner as set forth in the Corporate Governance Guidelines, then the name of that nominee and related biographical information should be forwarded to the Governance Committee, in care of the Secretary, at least six months before the next annual meeting of shareholders to assure time for meaningful consideration by the Governance Committee. In 2024, Plexus did not receive any recommendations for director nominees put forward by any shareholders.

The Plexus board of directors conducts an annual self-evaluation, which focuses on the performance of each individual director, the board’s committees and the board as a whole, as well as the composition of each of the board’s committees. The annual self-evaluation process provides an opportunity for anonymous peer review and specific feedback, which is intended to strengthen board leadership. The Chair of the Board is responsible for providing feedback to individual directors, while the Lead Director may also provide feedback and serve as a liaison between independent directors and the Chair. We believe this process encourages actionable feedback, which provides context for decisions about board composition, committee member rotation and succession planning processes.

The Governance Committee supervises a comprehensive, ongoing board refreshment and succession planning process to best position the board for continued success in alignment with the Company’s strategic objectives. This includes regularly assessing director skills and qualifications, reviewing director tenure, evaluating board diversity and board size, and performing annual board, committee and individual director assessments, as detailed above. In addition, the Governance Committee, with input from the Chair of the Board, reviews committee membership at least biennially and recommends committee assignments and committee rotation for approval by the entire board to ensure director skillsets are applied appropriately and to avoid director entrenchment.

The Governance Committee believes board refreshment is crucial to aligning board expertise with the Company’s evolving corporate strategy, but recognizes new directors need time to become familiar with the Company’s business and to develop relationships with other board members and management over time. As a result, the Governance Committee believes a continuum of tenure is required to enable the success of the board, with new members offering fresh perspectives while longer-serving directors offer necessary continuity and a deep understanding of the Company’s business. As applied in practice, 37.5% of our independent director nominees have been on the board fewer than 5 years.

In furtherance of this philosophy, the Company deploys a new director onboarding process and encourages continuing education to help augment and expedite the effectiveness of its newest board members. The Company also maintains a mandatory retirement policy, which states any individual age 75 or above is not eligible for election or re-election to the board of directors, unless such candidate is also a full-time employee of Plexus at the time or the board of directors, by majority vote, waives the restriction for a particular individual prior to such person’s election or re-election.

The board’s succession oversight extends to management as well. The board has developed and maintains an appropriate succession plan with respect to the position of CEO and other key executive positions. In addition, the Compensation Committee reviews and recommends to the board development plans for the CEO and other members of executive management.

Any communications to the board of directors should be sent to Plexus’ Global Headquarters in care of Plexus’ Secretary, Angelo M. Ninivaggi. Any communication sent to the board in care of the Chief Executive Officer, the Secretary or any other corporate officer also is forwarded to the board. There is no screening process, and any communication will be delivered directly to the director or directors to whom it is addressed.

Information related to our corporate governance practices, in addition to any new or proposed changes to procedures, are posted on our Corporate Governance page of our website at www.plexus.com under the link titled “Investors,” then “Corporate Governance” including:

The Governance Committee of the board of directors recommends, subject to board approval, compensation paid to non-employee directors, including equity awards under Company plans. In determining the compensation paid to the non-employee directors, the Governance Committee considers similar types of factors, including comparisons with the peer companies discussed below and Company performance, that are considered by the Compensation Committee when determining executive compensation. The Governance Committee aims to set the compensation level of our directors and the Non-Executive Chair near the median of peer and market comparisons. Non-employee director compensation is reviewed at least biennially.

As part of the most recent review of the non-employee director compensation program in fiscal 2023, the Governance Committee recommended, and the board approved, an increase in director base compensation upon review of peer and market data and in consultation with Exequity. As a result, beginning January 1, 2024, each non-employee director is compensated per the tables below. There will be no change for 2025.

In certain circumstances directors may be reimbursed for attending educational seminars or, in each individual’s capacity as a director, other meetings at Plexus’ behest. Directors do not receive board or committee meeting attendance fees.

For Mr. Foate’s service as Non-Executive Chair, he currently receives an annual retainer as reflected above, which was determined based upon a review of market and peer group practices, and he is eligible to receive an annual equity grant at least equal to the grants made to the Company’s other non-employee directors. In accordance with the Transition Agreement, Mr. Foate was eligible to participate in the Company’s executive car and phone programs, and he and his dependents were also eligible to participate in the Company’s health plan until he reached age 65, subject to his payment of the required premiums. These health plan benefits expired on October 2, 2023. Mr. Foate is otherwise compensated in accordance with Plexus’ policies for non-employee directors.

Plexus believes that it is important for directors to maintain an equity stake in Plexus to further align their interests with those of our shareholders. Therefore, directors must comply with stock ownership guidelines as determined by the board. The ownership guidelines currently require each director to own and maintain shares of common stock with a value equal to at least five times the director’s annual base cash retainer. The required ownership must be achieved within five years from the director’s initial election or appointment. Restricted stock (including RSUs) that has yet to vest does not count toward a director’s

ownership for purposes of these guidelines. Seven of our nine non-employee directors are currently in compliance with the ownership requirements of the guidelines. Mr. Martinez has until 2026 and Ms. Wuamett has until 2027 to meet these requirements, and each may not sell shares of Plexus common stock until ownership requirements are met.

Stock ownership guidelines for executives are discussed in “Compensation Discussion and Analysis—Elements and Analysis of Direct Compensation—Equity Ownership Guidelines.”

For information regarding the Company’s anti-hedging and anti-pledging policy, which is applicable to directors as well as executive officers and other employees, see “Compensation Discussion and Analysis—Elements and Analysis of Director Compensation—Anti-Hedging and Anti-Pledging Policy.”

Directors participate in the 2024 Omnibus Incentive Plan (the “Incentive Plan”), which permits the grant of stock options, stock appreciation rights (“SARs”), restricted stock, which may be designated as restricted stock shares or RSUs, performance stock awards (which may be settled in cash or stock and designated as performance stock shares or performance stock units (“PSUs”)), other stock awards and cash incentive awards. The Incentive Plan provides for an annual cap on the amount of awards to individual non-employee directors. The use of equity awards is designed to align directors’ interests with the long-term ownership interests of our shareholders. In the second quarter of fiscal 2024, each non-employee director serving on the grant date received a grant of RSUs worth approximately $190,000. The number of RSUs granted was determined based on the average closing price of the Company’s stock during the 90 calendar day period ended December 1, 2023. The restrictions on the RSUs generally lapse on the first anniversary of the grant date.

Directors are eligible to defer their cash fees, as well as stock awards (excluding options), through the Non-Employee Directors Deferred Compensation Plan. Amounts in deferred cash accounts are credited with interest, compounded monthly, at the prime rate of interest, which is determined quarterly. Directors were previously eligible to defer their cash fees through Plexus’ supplemental executive retirement plan, which is described in “Compensation Discussion and Analysis” below.

Aptly managing enterprise risks and opportunities is a critical part of our governance infrastructure. Our enterprise risk management (“ERM”) approach and control framework includes board oversight paired with integrated participation at all levels of the organization in order to ensure identification, assessment and appropriate response to risks and opportunities that may affect our ability to achieve our strategic objectives. This includes oversight by our executive Compliance, Ethics and Risk Committee, which includes our President and CEO, and process execution by the Risk Oversight Council, a cross-functional global council of employees led by our Enterprise Risk Manager. Our risk methodology includes: processes to categorize and quantify the likelihood and impact of risks; risk appetite and tolerance review; risk mitigation and opportunity strategies; and subsequent strategic integration through the establishment of key risk indicators and controls, and recalibration of risk tolerances.

This framework aims to establish an effective risk oversight program that successfully integrates risk management practices throughout the organization, enables open communication between management and directors and ensures all directors are actively involved in the risk oversight function. In addition, our board structure provides express committee oversight over critical areas of enterprise risk, including cybersecurity, environmental, social and governance matters, and human capital. We also employ independent internal and external audit procedures to help validate key controls related to identified risks, the results of which are reported to the board regularly. The board receives updates between board meetings with regard to issues that could materially impact the business, including through our business continuity and crisis communications protocols.

Information security and data privacy risk management, including cybersecurity, is integrated into and aligns with our ERM processes. Our information protection and privacy program incorporates administrative, technical and physical safeguards, and incorporates various cybersecurity and internal control frameworks to protect information assets, manage data privacy and ensure compliance with laws and industry standards. We leverage the National Institute of Security and Technology (NIST) Cybersecurity Framework, among others, to provide a strategic and adaptable approach to managing evolving cyber risks. This framework assists in assessing and improving our security posture by identifying vulnerabilities and prioritizing investments or improvements.

We maintain a cybersecurity incident response plan to assist in the assessment and management of cybersecurity incidents. The plan includes tactical playbooks and crisis response procedures based on incident severity and materiality impact. These crisis response procedures include escalation to the Audit Committee and the board, where appropriate. Our incident response plan is periodically tested through tabletop exercises, the results of which are reported to the Audit Committee.

Our Chief Information & Technology Officer (“CITO”), who reports directly to the President and CEO, directs our global information technology vision and long-term strategies. Under the direction of the CITO, the Director of Cybersecurity leads our enterprise-wide cybersecurity program and oversees a dedicated global cybersecurity team that monitors, assesses and mitigates material risks from various cybersecurity threats. This team leads critical efforts to drive readiness, awareness and learning across the organization, including management of a 24x7x365 Cybersecurity Operations Center for detection and response capabilities; maintaining a cybersecurity awareness learning management system; and third party assessments and audits, penetration tests and “red team” assessments to evaluate the effectiveness of cybersecurity controls and identify areas of cybersecurity risk.

Our executive-level Security Steering Committee provides oversight of cybersecurity, data governance and privacy programs. This Committee is made up of select executives including the General Counsel, Chief Administrative Officer and Secretary (“CAO”); Chief Operating Officer; and CITO. The Security Steering Committee provides oversight and ensures program alignment to Plexus’ strategic goals. The committee serves to provide awareness and guidance to prioritization, organizational alignment and enablement of resources to minimize risk to Plexus’ operations, brand and reputation. The Security Steering Committee, through the Director of Cybersecurity and the CITO, reports to a broader Information Technology (“IT”) Steering Committee, which includes the President and CEO and Chief Financial Officer.

On at least an annual basis, and on topical information security matters more frequently as determined by the board or management, the Audit Committee reviews the effectiveness of IT risk governance and management, including those relating to business continuity, cybersecurity, malware, regulatory compliance and data management. These reviews also include reviewing the appropriateness of resources (people and financial) devoted to information technology requirements. The CITO and Director of Cybersecurity also brief the Audit Committee quarterly on cybersecurity matters, including specific risks, mitigation plans, risk management and governance. The Audit Committee reports to the board on these discussions as appropriate.

Further, the board is briefed periodically (at least annually) on our overall IT strategy, including cybersecurity, to ensure alignment with the business, review of assets and infrastructure, and trends, key risks and initiatives.

Our board conducts a self-evaluation annually on a number of key qualifications, attributes, skills and experiences, as set forth above in “Board and Committee Self-Evaluation Process.” Through this self-evaluation process, all 10 of our director nominees identified as having experience managing cybersecurity practices in a multi-national organization.

Our focus on sustainable and responsible business practices is vital to realizing our vision to help create the products that build a better world. Our enduring strategy delivers value through our unique market focus, superior execution, a passionate and engaged workforce and a disciplined corporate model. As a new climate economy emerges and market dynamics shift, we are uniquely positioned to deliver more sustainable and responsible products and product lifecycle solutions for our customers, while attracting and retaining team members who align to this value proposition. Through our integrated strategic approach, the positive impact we can achieve through our efforts is transformative—for people, customers, our business and the planet.

Our integrative approach requires leadership engagement and oversight at the highest levels in order to assess risks and opportunities and to advance more sustainable and responsible business practices deep into our organization. The board engages regularly on our sustainability program and enterprise risks and is updated annually on our enterprise sustainability strategy and on topical sustainability matters more frequently as determined by the board or management. Plexus provides regular updates between board meetings with regard to issues that could materially impact the business, including through our business continuity and crisis communications protocols.

The executive Sustainable & Responsible Business Practices Committee—which includes our President and CEO and is chaired by our CAO—oversees integration of sustainable and responsible business practices into Plexus’ business strategy, sets short and long-term goals, including those that may be tied to executive compensation, and drives organizational engagement and accountability. The Sr. Director of Sustainability & Social Impact, along with their direct reports and dedicated resources throughout the organization, works closely with the Sustainable & Responsible Business Practices Committee to converge on a strategy that will create long-term value for the business, meet key stakeholder expectations and ensure accountabilities are effectively embedded throughout the organization.

This organizational framework enables us to effectively assess and address emerging social and environmental risks and opportunities, establish focus areas and goals, and align the organization to effectively execute on key priorities.

In addition to our executive incentive initiatives, discussed in “Compensation Discussion & Analysis,” our fiscal 2024 advancement efforts to build a better world included:

In fiscal 2024, Plexus published its annual Sustainability Report, reflecting its commitment to driving transparency and helping to coordinate sustainable and responsible practices across stakeholder groups. More detailed information about Plexus’ sustainability efforts and progress can be found in that report located at https://www.plexus.com/en-us/corporate-social-responsibility. The information in the Sustainability Report and on Plexus’ website is not a part of this proxy statement and is not incorporated by reference.

executive officers. Plexus provides further detail regarding executive compensation in the tables and other information included in the “Executive Compensation” section of this proxy statement.

As previously announced, Mr. Frisch retired as the Company’s Chief Strategy Officer effective September 28, 2024.

The Committee’s philosophy is to competitively compensate all employees, including executives, for their contributions to Plexus, to appropriately motivate employees to provide value to Plexus’ shareholders and to consider the ability of Plexus to fund any compensation decisions, plans or programs. Competitive compensation must balance both short-term and long-term considerations and take into account external forces, best practices, and the performance of Plexus and the employee. Compensation packages should also motivate executives to make decisions and pursue opportunities that are aligned with the interests of our shareholders, while not exposing the Company to excessive risk. Finally, the Committee considers Plexus’ financial condition, the conditions in Plexus’ industry and end markets, Plexus’ performance compared to its competitors, and the effects of those conditions on Plexus’ sales and profitability in making compensation decisions as well as the outcome of the advisory vote on executive compensation at the prior annual shareholders meeting. At our last annual meeting, approximately 86% of the shareholder votes cast on the proposal were cast in favor of the resolution, demonstrating that shareholders generally approve of our executive compensation program.

The Company continues to emphasize annual and long-term incentive opportunities as a portion of total compensation since they are performance-based, represent compensation that is at risk, promote the creation of shareholder value and are intended to align the interests of executive officers with those of our shareholders.

The Committee and the Company believe that shareholder value is maximized through revenue growth and generating a ROIC that exceeds the Company’s WACC. We refer to the amount of excess return when comparing these measures as economic return. The importance of achieving revenue growth and economic return goals has been emphasized by making a substantial component of each executive officer’s compensation dependent on the Company’s achievement of these goals, with executives maximizing their annual incentive compensation opportunity if the Company achieves its organic revenue growth and economic return goals.

Within our long term incentive plan we use economic return as a performance measure for PSUs. Relative TSR is also used as a performance measure for PSUs. The Committee believes it is important to balance absolute and relative measures in an effort to account for both internal and external influences on Company performance. The performance measures used by the Company’s annual and long-term incentive plans are described further in the “Elements and Analysis of Direct Compensation.”

Finally, the Committee recognizes that certain non-financial goals are important to position the Company for sustainable long-term success. The Committee works with management to identify these goals and they often comprise personal objectives under the VICP. These goals could include execution metrics, important system and process improvements, talent development priorities, and ESG initiatives, amongst others.

Below are illustrations of the performance of our compensation program measures and their relationship to creating shareholder value. To drive value, both growth and economic return¹ are critical.
