ANNUAL MEETING OF SHAREHOLDERS

FEBRUARY 13, 2013

COMMONLY ASKED QUESTIONS AND ANSWERS ABOUT THE ANNUAL MEETING

Q: WHEN IS THIS PROXY MATERIAL FIRST AVAILABLE TO SHAREHOLDERS?

A: On or about December 14, 2012, Plexus Corp. (“Plexus”, “we” or the “Company”) expects to mail shareholders a Notice of Internet Availability of Proxy Materials containing instructions on how to access the proxy material over the internet.

Q: WHY DID I RECEIVE A NOTICE OF INTERNET AVAILABILITY OF PROXY MATERIALS INSTEAD OF A PRINTED COPY OF THE PROXY MATERIAL?

A: Pursuant to the rules adopted by the Securities and Exchange Commission, we are permitted to provide access to our proxy material over the internet instead of mailing a printed copy of the proxy material to each shareholder. As a result, we are mailing shareholders a Notice of Internet Availability of Proxy Materials containing instructions regarding how to access our proxy material, including our proxy statement and annual report, and vote via the internet. You will not receive a printed copy of the proxy material unless you request one by following the instructions included in the Notice of Internet Availability of Proxy Materials or provided below.

Important Notice Regarding the Availability of Proxy Materials for

the Shareholder Meeting to Be Held on February 13, 2013

The proxy statement and annual report are available at www.proxyvote.com.

At www.proxyvote.com, shareholders can view the proxy material, cast their vote and request to receive paper copies of the proxy material by mail.

Q: HOW CAN SHAREHOLDERS REQUEST PAPER COPIES OF THE PROXY MATERIAL?

A: Shareholders may request that paper copies of the proxy material, including an annual report, proxy statement and proxy card, be sent to them without charge as follows:

• By internet:	www.proxyvote.com
• By email:	Send a blank email with your 12 digit control number(s) in the subject line to sendmaterial@proxyvote.com
• By telephone:	1-800-579-1639

When you make your request, please have your 12 digit control number(s) available; that control number was included in the notice that was mailed to you. To assure timely delivery of the proxy material before the annual meeting, please make your request no later than January 30, 2013.

1

Q: WHAT AM I VOTING ON?

A: At the annual meeting you will be voting on three proposals:

1. The election of nine directors to the board of directors to serve until Plexus’ next annual meeting and until their successors have been duly elected. This year’s nominees are:

• Ralf R. Böer • Stephen P. Cortinovis • David J. Drury • Dean A. Foate • Rainer Jueckstock • Peter Kelly • Phil R. Martens • Michael V. Schrock • Mary A. Winston

2. A proposal to ratify the Audit Committee’s selection of PricewaterhouseCoopers LLP as Plexus’ independent auditors for 2013.

3. An advisory proposal to approve the compensation of the Company’s named executive officers, as disclosed in “Compensation Discussion and Analysis” and “Executive Compensation” herein.

Q: WHAT ARE THE BOARD’S VOTING RECOMMENDATIONS?

A: The board of directors is soliciting this proxy and recommends the following votes:

• FOR each of the nominees for election to the board of directors;

• FOR the ratification of the Audit Committee’s selection of PricewaterhouseCoopers LLP as Plexus’ independent auditors for 2013; and

• FOR approval of the compensation of the Company’s named executive officers.

Q: WHAT VOTE IS REQUIRED TO APPROVE EACH PROPOSAL?

A: To conduct the annual meeting, more than 50% of the Plexus’ outstanding shares entitled to vote must be present in person 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.

Assuming a quorum is present, directors are elected by a plurality of the votes cast in person or by proxy by the holders of Plexus common stock entitled to vote at the election at the meeting. “Plurality” means that the individuals who receive the highest number of votes are elected as directors, up to the number of directors to be chosen at the meeting. Any votes attempted to be cast “against” a candidate are not given legal effect and are not counted as votes cast in the election of directors. 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.

Ratification of PricewaterhouseCoopers LLP as Plexus’ independent auditors will be determined by a majority of the shares voting on that matter, assuming a quorum is present. In addition, assuming a quorum is present, the results of the advisory vote to approve the compensation of the Company’s named executive officers will also be determined by a majority of shares voting on such matter. Abstentions and broker non-votes will not affect these votes, except insofar as they reduce the number of shares that are voted.

2

Q: WHAT IF I DO NOT VOTE?

A: The effect of not voting will depend on how your share ownership is registered.

If you own shares as a registered holder and you do not vote, the shares that you do not vote 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. In the absence of your voting instructions, your bank, broker or other holder of record may or may not vote your shares in its discretion depending on the proposal before the meeting. Your broker may no longer vote your shares in its 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 also not permitted to vote your shares in its discretion regarding matters related to executive compensation, including advisory votes to approve executive compensation. However, your broker may vote your shares in its discretion on routine matters such as the ratification of the Plexus’ independent auditors.

Q: WHO MAY VOTE?

A: You may vote at the annual meeting if you were a shareholder of record of Plexus common stock as of the close of business on December 6, 2012, which is the “Record Date.” As of the Record Date, Plexus had 34,968,050 shares of common stock outstanding. Each outstanding share of common stock is entitled to one vote on each matter presented. Any shareholder entitled to vote may vote either in person or by duly authorized proxy.

Q: HOW DO I VOTE?

A: We offer four methods for you to vote your shares at the annual meeting—in person; via the internet; by telephone; or by mail. You may vote in person at the annual meeting or authorize the persons named as proxies on the proxy card, Dean A. Foate, Ginger M. Jones and Angelo M. Ninivaggi, to vote your shares. We recommend that you vote as soon as possible, even if you are planning to attend the annual meeting, so that the vote count will not be delayed.

While we offer four methods, we encourage you to vote via the internet, as it is the most cost-effective method available. There is no charge to vote your shares via the internet, though you may incur costs associated with electronic access, such as usage charges from internet access providers. If you choose to vote your shares via the internet, there is no need for you to request or mail back a proxy card.

•  By internet:	Go to www.proxyvote.com. Please have the notice we sent to you in hand because it has your personal 12 digit control number(s) needed for your vote.
•  By telephone:	On a touch-tone telephone, call 1-800-690-6903. Please have the notice we sent to you in hand because it has your personal 12 digit control number(s) needed for your vote.
•  By mail:	Please request written materials as provided on page 1 of the proxy statement. Complete, sign and date the proxy card, and return it to the address indicated on the proxy card.

If your shares are not registered in your name, then you vote by giving instructions to the firm that holds your shares rather than using any of these methods. Please check the voting form of the firm that holds your shares to see if it offers internet or telephone voting procedures.

3

Q: WHAT DOES IT MEAN IF I RECEIVE MORE THAN ONE REQUEST TO VOTE?

A: It means your shares are held in more than one account. You should vote the shares on all of your proxy requests. You may help us reduce costs by consolidating your accounts so that you receive only one set of proxy materials in the future. To consolidate your accounts, please contact our transfer agent, American Stock Transfer & Trust Company, LLC, toll-free at 1-800-937-5449.

Q: WHAT IF I OWN SHARES AS PART OF PLEXUS’ 401(k) SAVINGS PLAN AND/OR EMPLOYEE STOCK PURCHASE PLANS?

A: Shareholders who own shares as part of Plexus’ 401(k) Savings Plan (the “401(k) Plan”) and/or the Plexus 2000 and 2005 Employee Stock Purchase Plans (the “Purchase Plans”) will receive a separate means for proxy voting their 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 on the votes for which voting directions have been received from participants. Shares held in accounts under the Purchase Plans will be voted in accordance with management recommendations, except for shares for which contrary designations from participants are received.

Q: WHO WILL COUNT THE VOTE?

A: Broadridge Financial Solutions, Inc. will use an automated system to tabulate the votes. Its representatives will also serve as the election inspectors.

Q: WHO CAN ATTEND THE ANNUAL MEETING?

A: All shareholders of record as of the close of business on December 6, 2012, can attend the meeting. However, seating is limited and will be on a first arrival basis.

To attend the annual meeting, please follow these instructions:

• Bring proof of ownership of Plexus common stock and a form of identification; or

• If a broker or other nominee holds your shares, bring proof of ownership of Plexus common stock through such broker or nominee and a form of identification.

Q: CAN I CHANGE MY VOTE AFTER I RETURN OR SUBMIT MY PROXY?

A: Yes. Even after you have submitted your proxy, proxies may be revoked at any time prior to the voting thereof either by written notice filed with the secretary or acting secretary of the meeting or by oral notice to the presiding officer during the meeting. Presence at the annual meeting of a shareholder who has appointed a proxy does not in itself revoke a proxy.

Q: MAY I VOTE AT THE ANNUAL MEETING?

A: If you complete a proxy card or vote via the internet, you may still vote in person at the annual meeting. To vote at the meeting, please either give written notice that you would like to revoke your original proxy to the secretary or acting secretary of the meeting or oral notice to the presiding officer during the meeting.

If a broker, bank or other nominee holds your shares and you wish to vote in person at the annual meeting you must obtain a proxy issued in your name from the broker, bank or other nominee; otherwise you will not be permitted to vote in person at the annual meeting.

4

Q: WHO IS MAKING THIS SOLICITATION?

A: This solicitation is being made on behalf of Plexus by its board of directors. Plexus will pay the expenses in connection with the solicitation of proxies. Upon request, Plexus will reimburse brokers, dealers, banks and voting trustees, or their nominees, for reasonable expenses incurred in forwarding copies of the proxy material and annual report to the beneficial owners of shares which such persons hold of record. Plexus will solicit proxies by mailing a Notice of Internet Availability of Proxy Materials to all shareholders; paper copies of the proxy material will be sent upon request as provided above as well as in the Notice of Internet Availability of Proxy Materials. Proxies may be solicited in person, or by telephone, e-mail or fax, by officers and regular employees of Plexus who will not be separately compensated for those services.

Q: WHEN ARE SHAREHOLDER PROPOSALS AND SHAREHOLDER NOMINATIONS DUE FOR THE 2014 ANNUAL MEETING?

A: The Secretary must receive a shareholder proposal no later than August 16, 2013, in order for the proposal to be considered for inclusion in our proxy materials for the 2014 annual meeting. The 2014 annual meeting of shareholders is tentatively scheduled for February 12, 2014. To otherwise bring a proposal or nomination before the 2014 annual meeting, you must comply with our bylaws. Currently, our bylaws require written notice to the Secretary between October 5, 2013, and October 30, 2013. 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 30, 2013, then your proposal or nomination will be untimely. 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.

Q: WHAT IS THE ADDRESS OF THE SECRETARY?

A: The address of the Secretary is:

Plexus Corp.

Attn: Angelo M. Ninivaggi

One Plexus Way

P.O. Box 156

Neenah, Wisconsin 54957-0156

Q: WILL THERE BE OTHER MATTERS TO VOTE ON AT THIS ANNUAL MEETING?

A: We are not aware of any other matters that you will be asked to vote on at the annual meeting. Other matters may be voted on if they are properly brought before the annual meeting in accordance with our bylaws. If other matters are properly brought before the annual meeting, then the named proxies will vote the proxies they hold in their discretion on such matters.

For matters to be properly brought before the meeting, our bylaws require that we receive written notice, together with specified information, not less than 45 days nor more than 70 days before the first anniversary of the date in which proxy materials for the previous year’s annual meeting were first made available to shareholders. We did not receive notice of any matters by the deadline for the 2013 annual meeting, which was November 1, 2012.

(1) The specified persons have sole voting and sole dispositive powers as to all shares, except as otherwise indicated. The amounts include shares subject to options granted under Plexus’ option plans which are exercisable currently or within 60 days of December 6, 2012. The options include those held by Mr. Böer (58,500 shares), Mr. Cortinovis (67,000), Mr. Drury (55,000), Mr. Foate (647,625), Mr. Kelly (55,000), Mr. Martens (10,000), Mr. Nussbaum (27,500), Mr. Schrock (45,000), Ms. Winston (24,000), Ms. Jones (86,625), Mr. Buseman (86,375), Mr. Kelsey (91,375) and Mr. Lim (90,625), and all executive officers and directors as a group (1,536,392). While the total for all executive officers and directors as a group includes 17 shares that may be acquired pursuant to stock-settled stock appreciation rights (“SARs”) granted under Plexus’ equity incentive plans that are currently vested, it excludes certain SARs because the respective exercise prices of those SARs were below the market value of Plexus common stock on December 6, 2012. SARs are owned by an individual who is neither a director nor an executive officer named in the “Summary Compensation Table.”

The amounts reported in the table for executive officers also include shares subject to acquisition within 60 days of December 6, 2012, upon the vesting of restricted stock units (“RSUs”) granted under Plexus’ equity plans as follows: Mr. Foate (20,500), Ms. Jones (5,000), Mr. Buseman (6,250), Mr. Kelsey (6,250) and Mr. Lim (5,000), and all executive officers and directors as a group (53,500).

ELECTION OF DIRECTORS

Plexus believes that it needs to attract and retain talented, focused, and motivated leadership to develop the long-term strategy and deliver the economic profit that our shareholders expect. For Plexus, the concept of leadership is not limited to the leadership within the Company; leadership also includes the individuals who serve on Plexus’ board.

In accordance with Plexus’ bylaws, the board of directors has determined that there shall be nine directors elected at the annual meeting of shareholders to serve until their successors are duly elected and qualified. The persons 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 not foreseen, the proxies will be voted with discretionary authority for a substitute nominee designated by the board of directors. Plexus’ bylaws authorize up to ten directors, as determined by the board. The Plexus board may expand the board up to the number of directors authorized in Plexus’ bylaws and elect directors to fill empty seats, including those created by an expansion, between shareholders’ meetings.

John L. Nussbaum, a co-founder of Plexus and our former Chief Executive Officer, will be retiring as Chairman of the Board effective as of the annual meeting on February 13, 2013. Plexus and the board both sincerely thank Mr. Nussbaum for his years of dedicated service and many valuable contributions to Plexus.

CORPORATE GOVERNANCE

Board of Directors Meetings

The board of directors held four meetings during fiscal 2012. As part of these meetings, non-management directors regularly meet without management present. All of our directors attended at least 75% of the total meetings of the board and the committees of the board on which they served. The Plexus board of directors conducts an annual self-evaluation process, reviewing the performance of each individual board member as well as the performance of the board as a whole.

Plexus encourages all of its directors to attend the annual meeting of shareholders. 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. All directors attended the 2012 annual meeting of shareholders.

Director Independence

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 determination regarding which directors are independent, the board first considers and follows the Nasdaq Global Select Market rules. The board also reviews other transactions and relationships, if any, involving Plexus and the 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 inform it of any transaction, whether direct or indirect through an immediate family member or any business entity controlled by any of them, involving 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.

In determining independence for the coming year, the board considered two relationships that, upon review, the board did not believe affected the independence of the directors.

• Mr. Kelly is an executive officer of NXP Semiconductors N.V., which is a supplier to Plexus. Plexus’ payments to NXP’s distributors in fiscal 2012 represented less than two-tenths of one percent of each of Plexus’ and NXPs annual revenues.

• Mr. Schrock is an executive officer of Pentair Ltd., which is a supplier to Plexus. Plexus’ payments to Pentair in fiscal 2012 represented less than one-tenth of one percent of each of Plexus’ and Pentair’s annual revenues.

Based on the applicable standards and the board’s review and consideration, the board of directors has determined that Messrs. Böer, Cortinovis, Drury, Kelly, Martens and Schrock, and Ms. Winston are each “independent” under applicable rules and guidelines, and that Mr. Jueckstock would be “independent” if elected to the board. Mr. Foate, as chief executive officer of the Company, and Mr. Nussbaum, who is a former chief executive officer of Plexus and receives retirement payments from Plexus, are not considered to be “independent.”

Our independent directors have the opportunity to meet in executive session, without the other directors or management, as part of each regular board meeting.

12

Board Leadership Structure

Mr. Nussbaum, our former Chief Executive Officer, currently serves as the Chairman of the Board. As previously announced, Mr. Nussbaum will be retiring and Mr. Foate, our current Chief Executive Officer, has been elected as Chairman, effective after the annual meeting on February 13, 2013. The Company believes that having Mr. Nussbaum serve as Chairman in recent years has been an appropriate leadership structure for the board because Mr. Nussbaum, as our former CEO, has extensive knowledge of the Company and the EMS industry, which have been valuable in communicating with and leading the board in his role as Chairman.

In connection with its succession planning efforts, the board evaluated its leadership structure and determined that upon Mr. Nussbaum’s retirement, Mr. Foate would be appointed as Chairman primarily due to his in-depth knowledge of the Company and EMS industry, keen understanding of the Company’s operations and strategies, proven leadership and vision for Plexus, which position him to be able to provide strong and effective leadership of the board going forward. In addition, the board believes that Mr. Foate will be in the best position as Chairman and CEO 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.

The board does not have a policy that requires the separation of the roles of Chairman and CEO, 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, if the Chairman is also the CEO, the independent directors, meeting in executive session, will elect a lead director from among the independent directors. Therefore, in connection with the leadership changes discussed above, in November 2012, the independent directors of the Company’s board elected Mr. Schrock as lead director, also effective after the annual meeting on February 13, 2013. 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 chairman in terms of oversight, access and an independent voice with significant input into corporate governance.

The duties of the board’s lead director include: (i) presiding at all meetings of the board at which the Chairman is not present, including executive sessions of the independent directors; (ii) serving as liaison between the Chairman and the independent directors; (iii) together with the Chairman, approving the agendas for board meetings; (iv) together with the Chairman, approving meeting schedules to assure that there is sufficient time for discussion of all agenda items; (v) providing input to the Chairman as to the content, quality, quantity and timeliness of information from Company management to the board; (vi) having the authority to call meetings of the independent directors and develop the agendas for such meetings with input from the other independent directors; (vii) serving as a liaison for consultation and direct communication with major shareholders; and (viii) performing such other duties as the board or Chairman may from time to time delegate.

Board’s Role in Risk Oversight

It is management’s responsibility to manage the Company’s enterprise risks on a day-to-day basis. Through regular updates, the board of directors oversees management’s efforts to ensure that they effectively identify, prioritize, manage and monitor all material business risks to Plexus’ strategy.

The board delegates certain risk management oversight responsibilities to its committees. The Audit Committee reviews and discusses the Company’s major financial risk exposures and the steps management has taken to identify, monitor and control such risks. The Compensation and Leadership Development Committee is responsible for overseeing risk related to the Company’s compensation programs, including considering whether such programs are in line with the Company’s strategic objectives and incentivize appropriate risk-taking. The Nominating and Corporate Governance Committee is tasked with risks associated with corporate governance, compliance and ethics.

Board Committees

The board of directors has three standing committees, all comprised solely of independent directors: Audit, Compensation and Leadership Development, and Nominating and Corporate Governance. The committees on which our directors currently serve, and the chairs of those committees, are identified in the following table:

13

Director	Audit	Compensation and Leadership Development	Nominating and Corporate Governance
Ralf R. Böer			Chair
Stephen P. Cortinovis	X	Chair
David J. Drury	Chair		X
Peter Kelly	X	X
Phil R. Martens		X	X
Michael V. Schrock		X	X
Mary A. Winston	X

Messrs. Foate and Nussbaum are not “independent” directors; therefore, they are not eligible to serve on these committees under Nasdaq rules or the committees’ charters. Mr. Jueckstock’s prospective committee membership has not yet been determined.

Audit Committee

The Audit Committee met eight times in fiscal 2012. The Audit Committee chooses the Company’s independent auditors and oversees the audit process as well as the Company’s accounting, finance and tax functions. Among its other responsibilities, the Committee also oversees the Company’s ethics and whistle-blowing reporting programs, in conjunction with the Nominating and Corporate Governance Committee. See also “Report of the Audit Committee.”

Audit Committee Financial Experts

The board has determined that Messrs. Drury and Kelly and Ms. Winston are “audit committee financial experts” based on a review of each individual’s educational background and business experience. For purposes of Securities and Exchange Commission (“SEC”) and Nasdaq rules, Messrs. Drury and Kelly and Ms. Winston are, along with Mr. Cortinovis, the other member of the Audit Committee, “independent” of Plexus. All members of the Audit Committee are “financially literate” and meet the other SEC and Nasdaq requirements for Audit Committee membership.

Compensation and Leadership Development Committee

The Compensation and Leadership Development Committee (in this subsection, the “Committee”) held six meetings during fiscal 2012. The Committee establishes the general compensation philosophies and plans for Plexus, determines the CEO’s and other executive officers’ compensation and approves equity grants and awards under Plexus’ compensation plans. The Committee also considers and makes recommendations to the board with respect to other employee compensatory plans and arrangements. Further, the Committee is responsible for reviewing Plexus’ leadership structure, talent management efforts, leadership development and executive succession plans. In addition to the following subsection, see also “Compensation Discussion and Analysis” and “Compensation Committee Report” below for further information on the Committee’s philosophies and practices, and its determinations in fiscal 2012.

Overview of the Compensation Decision-Making Process

In accordance with the philosophy and the goals described below in “Compensation Discussion and Analysis,” Plexus compensates its executive officers through salaries and various other compensation plans. The Committee considers many factors in its decision-making process about the compensation of Plexus’ leadership and the design of compensation plans company-wide.

When determining compensation in fiscal 2012, as in past years, the Committee compared the compensation of Plexus’ executive officers with that paid by other companies in the general industries in which Plexus recruits, comparable companies in the electronic manufacturing services industry, companies with similar financial profiles and several general and electronics industry published surveys. The Committee performed a full review of the composition of the peer group during fiscal 2010 because, due to acquisitions within the peer group

14

and other changes, the Committee believed that certain companies had become less comparable to Plexus than when they were originally selected. The Committee intends to conduct reviews of the peer group and selection criteria on a periodic basis to ensure that both are appropriate. Consistent with the selection of its previous peer group, companies were chosen using filtering criteria, such as industry codes, peer companies identified as competitors, company size and employee base, profitability, geographic location, company complexity and recent financial performance; anomalies or special circumstances (primarily acquisitions or significant size differences) that caused certain companies to not be in fact comparable were also reviewed. In addition, the Committee also identified financial peers that were not in a similar business but which were similar in size and financial performance to Plexus.

Our resulting peer group for fiscal 2012 compensation planning consisted of:

• Agilent Technologies, Inc.	• Bruker Corporation	• Molex Incorporated
• Altera Corporation	• Celestica Inc.	• Regal-Beloit Corporation
• Amphenol Corporation	• Esterline Technologies Corporation	• Sanmina-SCI Corporation
• Arris Group, Inc.	• Harris Corporation	• Teledyne Technologies Incorporated
• AVX Corporation	• Invacare Corporation	• Trimble Navigation Limited
• Benchmark Electronics, Inc.	• Jabil Circuit, Inc.	• Vishay Intertechnology, Inc.

This peer group is being used for fiscal 2013 executive compensation planning.

When making compensation determinations, the Committee’s analysis includes a review of the Company’s financial results, an internal calibration of pay and equity award levels and an accumulated value analysis. In performing these analyses, the Committee continues to use tally sheets, which provide a comprehensive view of Plexus’ compensation payout exposure under various performance scenarios, and also assist in the Committee’s evaluation of the reasonableness of compensation as a whole. The accumulated value analysis examines the CEO’s accumulation of wealth through the deferred compensation plan and annual equity awards. These assessments also identify the proportionality of the CEO’s pay to the pay of executives at other levels in the organization and compare this information with published survey data. In addition, the Committee uses the vested and unvested equity information to balance the level of existing awards with the desire to reward performance and to provide retention incentives.

In addition to reviewing compensation to help assure that it provides an incentive for strong Company performance, the Company and the Committee periodically review comparable information from peer group companies and other sources, as discussed above, to maintain a competitive compensation package that aids in executive retention and fairly compensates the executives for performance. However, it does not aim for any numerical or percentile tests within this comparable information. The Committee believes that it is important for it to use its judgment in applying this information in individual cases, rather than arbitrarily attempting to aim for a particular numerical equivalence. In that consideration, the Committee discusses total compensation (including outstanding equity awards) for all executive officers, the level of experience and leadership each provides, and financial and personal performance results. The Committee seeks to balance different types of compensation in order to promote retention and strong Company performance. The Committee believes this approach results in a comprehensive and thoughtful compensation review process because it allows the Committee to use discretion when appropriate in responding to particular circumstances. The Committee intends to continue these practices in the future.

Management Participation. Members of management, particularly the CEO and human resources personnel, regularly participate in the Committee’s meetings at the Committee’s request. Management’s role is to contribute information to the Committee and provide staff support and analysis for its discussions. However, management does not make any recommendation for the CEO’s compensation, nor does management make the final determination of the CEO’s or the other executive officers’ amount or form of executive compensation. The CEO does recommend compensation for the other executive officers to the Committee, subject to the Committee’s final decision. To assist in determining compensation recommendations for the other executive officers, the CEO considers Plexus’ compensation philosophy and, in partnership with the human resources management team, utilizes the same compensation decision-making process as the Committee. Decisions regarding the compensation of the CEO are made in executive sessions at which the Committee members participate with select members of human

15

resources management to review competitive practices and overall plan expense; the CEO is not present for these discussions. The sessions generally focus on the CEO’s performance achievement and the elements of his compensation. The Committee also discusses and reviews materials comparing the CEO’s compensation to peer group and survey data as well as Plexus’ overall performance relative to the companies in our peer group. Materials presented also include a pay comparison of the CEO to our other executive officers and a review of the CEO’s vested and unvested equity grants, as well as accumulated value, in an effort to assess possible retention risks.

Use of Consultants. The Committee uses outside compensation consultants to assist it in analyzing Plexus’ compensation programs and in determining appropriate levels of compensation and benefits. The Committee is directly responsible for the appointment, termination, compensation and oversight of the work of any such compensation consultant(s). The Company provides appropriate funding, as determined by the Committee, for the payment of compensation to the compensation consultant(s) employed by the Committee. The Committee currently retains Towers Watson as its compensation consultant.

Plexus human resources personnel meet with the compensation consultants to help the consultants understand Plexus’ business model, organizational structure and compensation philosophy. This interaction provides the consultants with a framework to Plexus’ approach to compensation and its application. As part of its staff support function, Plexus human resources personnel also discuss results and conclusions with the compensation consultants. These discussions permit Plexus human resources personnel to be aware of the consultants’ recommendations and analysis, as well as to understand the rationale and methodology behind their conclusions.

For fiscal 2012 compensation planning, the Committee directed the Company’s internal human resources staff to prepare an analysis of the Company’s executive compensation package consistent with prior years. Plexus’ internal staff obtained market-based data to provide the Committee with the same data and analysis as in previous years. In future years, the Committee may retain Tower Watson or another independent compensation consultant to conduct a detailed analysis of the Company’s executive compensation package.

Neither the Company nor the Committee places any limitations or restrictions on its consulting firms or their reviews. Towers Watson and previous consulting firms have been retained by the Committee only for projects related to the Company’s executive and director compensation programs. The Company does provide substantive information about Plexus to help its consultants better understand the Company. Human resources personnel also meet with the consultants to discuss the consultants’ conclusions as to Plexus’ executive pay practices, organizational matters, the duties and responsibilities of particular positions, and overall conclusions based upon Plexus’ compensation principles and goals. After considering the factors set forth in the final SEC and proposed Nasdaq rules, the Committee does not believe its relationship with Towers Watson has given rise to any conflict of interest.

Compensation Committee Interlocks and Insider Participation

Each of the members of the Committee was an independent director and there were no relationships or transactions in fiscal 2012 with those members requiring disclosure under SEC rules. See, however, “Director Independence” above for certain other relationships that the board considered when determining the independence of the directors.

Nominating and Corporate Governance Committee

The Nominating and Corporate Governance Committee (the “Nominating Committee”) met five times in fiscal 2012. The Nominating Committee considers candidates for board membership, reviews the effectiveness of the board, makes recommendations to the board regarding directors’ compensation, monitors Plexus’ compliance and ethics efforts, and evaluates as well as oversees corporate governance and related issues.

The Nomination Process

The Nominating Committee generally utilizes a director search firm to identify candidates, but it evaluates those individuals on its own; the Committee would also consider candidates suggested by outside directors, management and/or shareholders. As described above in “Election of Directors,” in accordance with the Company’s board member selection criteria, the Nominating Committee considers the diversity of backgrounds, skills and

16

experiences among board members in identifying areas which 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 composition of the Board is reviewed annually to insure 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 Nominating Committee would consider proposed nominees to the board submitted to it by shareholders. If a qualified candidate expresses a serious interest, and if there is a position available and the candidate’s experience indicates that the candidate may be an appropriate addition to the board, the Nominating Committee would review the background of the candidate and, if appropriate, meet with the candidate. A decision would then be made whether to nominate that person to the board. The Nominating Committee’s policy is to not evaluate proposed nominees differently depending upon who has proposed the potential nominee.

If a shareholder wishes to propose someone as a director for the Nominating Committee’s consideration, the name of that nominee and related personal information should be forwarded to the Nominating 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 Nominating Committee. See also “Commonly Asked Questions and Answers About the Annual Meeting” for bylaw requirements for nominations. Plexus has neither received nor rejected any candidates put forward by significant shareholders.

Communications with the Board

Any communications to the board of directors should be sent to Plexus’ headquarters office 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 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. Any other procedures which may be developed, and any changes in those procedures, will be posted as part of our Corporate Governance Guidelines on Plexus’ website at www.plexus.com, under the link titled “Investor Relations” then “Corporate Governance.”

Code of Ethics, Committee Charters and Other Corporate Governance Documents

Plexus regularly reviews and augments its corporate governance practices and procedures. As part of its corporate governance practices, Plexus has adopted a Code of Conduct and Business Ethics, Corporate Governance Guidelines and written charters for each of its board committees discussed above. Plexus will be responding to and complying with related SEC and Nasdaq Global Select Market directives as they are finalized, adopted and become effective. Plexus has posted on its website, at www.plexus.com, under the link titled “Investor Relations” then “Corporate Governance,” copies of its Code of Conduct and Business Ethics, its Corporate Governance Guidelines, the charters for its Audit, Compensation and Leadership Development, and Nominating and Corporate Governance Committees, director selection criteria (included as an appendix to our Corporate Governance Guidelines), director and officer stock ownership guidelines, compensation clawback policy and other corporate governance documents. If those documents (including the committee charters, the Code of Conduct and Business Ethics and the Corporate Governance Guidelines) are changed, waivers from the Code of Conduct and Business Ethics are granted, or new procedures are adopted, those new documents, changes, waivers and/or procedures will be posted on Plexus’ corporate website at the address above.

17

Directors’ Compensation

The Nominating and Corporate Governance Committee of the board of directors recommends, subject to board approval, compensation paid to non-employee directors, including equity awards to non-employee directors under the 2008 Long-Term Plan. In determining the compensation paid to the non-employee directors, the Nominating and Corporate Governance Committee considers similar types of factors, including comparisons with peer companies and Company performance, that are considered by the Compensation and Leadership Development Committee when determining executive compensation.

During fiscal 2012, each Plexus director who was not a full-time Plexus officer or employee (all directors except Mr. Foate, who does not receive additional fees for serving on the board) received an annual director’s fee of $55,000 plus meeting fees of $2,000 for each board meeting attended in person ($1,000 if attended other than in person) and an additional $1,500 for each committee meeting attended in person ($750 if other than in person). The chairs of each committee received additional annual fees for service in such roles; the Audit Committee Chair received $15,000, the Compensation and Leadership Development Committee Chair received $12,500 and the Nominating and Corporate Governance Committee Chair received $10,000. Mr. Nussbaum received an additional fee of $75,000 in fiscal 2012 for serving as Plexus’ non-executive Chairman of the Board. Additionally, 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. For fiscal 2013, board and committee meeting attendance fees, and the chairman of the board fee, have been eliminated. The annual director’s fee will increase to $65,000 and the lead director will receive an additional annual fee of $20,000 for serving in that role. Committee chair fees will remain the same. The other members of the committees will receive annual retainers for their service as follows: Audit Committee - $9,000; Compensation and Leadership Development Committee - $7,500; and Nominating and Corporate Governance Committee - $5,250.

Directors are eligible to defer their cash fees, as well as stock awards (excluding options), through the Non-Employee Directors Deferred Compensation Plan. Prior to fiscal 2011, directors were eligible to defer their cash fees through Plexus’ supplemental executive retirement plan, which is described in “Compensation Discussion and Analysis” below.

Directors may also participate in the 2008 Long-Term Plan, which permits the grant of stock options, stock-settled stock appreciation rights (“SARs”), restricted stock (which may be designated as restricted stock awards or restricted stock unit awards), unrestricted stock awards, performance stock awards, and cash incentive awards. In fiscal 2012, stock options were granted to directors quarterly, at the same time as employee grants, and vested immediately on the respective grant dates. The exercise price of each stock option grant was equal to the average of the high and low sale prices of Plexus stock on the Nasdaq Global Select Market on the grant date. In addition, unrestricted stock awards were granted to directors at the same time as employee equity grants during the second quarter of the fiscal 2012. Beginning in calendar year 2013, it is anticipated that directors will be granted restricted stock units, instead of a mix of stock options and unrestricted stock awards, during the second quarter of the fiscal year; the restrictions on these awards will lapse on the first anniversary of the applicable grant date. The use of equity awards is designed to align directors’ interests with the long-term ownership interests of our shareholders.

Mary A. Winston		69,500		67,635		73,580		—		210,715

(1) Includes annual retainer, meeting, committee and chairmanship fees and, in the case of Mr. Nussbaum, his fee for serving as Chairman of the Board. See below regarding Mr. Nussbaum’s compensation.

(2) The amounts shown represent the grant date fair value computed in accordance with Accounting Standards Codification Topic 718 of stock options and unrestricted stock awards granted in fiscal 2012. Generally accepted accounting principles (“GAAP”) require us to recognize compensation expense for stock options and other stock-related awards granted to our employees and directors based on the estimated fair value of the equity instrument at the time of grant. Compensation expense is recognized over the vesting period. The assumptions used to determine the valuation of the awards are discussed in footnote 10 to our consolidated financial statements.

The following table provides cumulative information about the grant date fair value of options and stock awards granted to directors in fiscal 2012, determined as of the respective grant dates in accordance with GAAP. It also provides the number of outstanding stock options that were held by our non-employee directors at September 29, 2012. The Company began granting unrestricted stock awards to directors in fiscal 2010; restricted stock awards were not granted to directors in fiscal 2012 or in any prior years.

Each non-employee director serving at the time was awarded options for 1,250 shares on each of October 31, 2011, January 23, 2012, April 23, 2012, and July 23, 2012. All options granted to non-employee directors vest immediately on the respective grant dates. Options granted to non-employee directors expire on the earlier of (a) ten years from the date of grant, or (b) two years after termination of service as a director. In addition, on January 23, 2012, each non-employee director received an unrestricted stock award for 2,000 shares; the average of the high and low trading prices of our shares on the Nasdaq Global Select Market on that date was $36.79. Messrs. Böer, Cortinovis, Martens and Nussbaum and Ms. Winston each elected to defer receipt of the 2012 unrestricted stock award.

(3) Other than Mr. Nussbaum, the non-employee directors do not receive any additional benefits although they are reimbursed for their actual expenses of attending board, committee and shareholder meetings. For Mr. Nussbaum, this represents the amounts paid to him in fiscal 2012 under his deferred compensation arrangements plus the value of the health and other welfare benefits, as well as Company matching contributions to the 401(k) Plan, provided to him. See the discussion immediately below.

Retirement Arrangement for Mr. Nussbaum

Mr. Nussbaum is a former executive officer of Plexus. He ceased being considered an executive officer or employee of Plexus when he retired as our Chief Executive Officer in 2002, and has been eligible to receive board fees and equity grants as a non-employee director since that time. However, as a consequence of his many years of service as an executive officer of Plexus, he continues to be compensated under deferred compensation arrangements which were put in place during his service as an executive officer and as the non-executive Chairman of the Board.

In 1996, the Compensation and Leadership Development Committee established special retirement arrangements for Mr. Nussbaum as well as for two other executive officers and directors who subsequently retired. Those arrangements were intended to both reward past service and maintain an additional incentive for those officers’ continued performance on behalf of Plexus. The related supplemental executive retirement agreement for Mr. Nussbaum was amended in 2009 in order to align the agreement’s provisions regarding the determination of payment amounts to a fixed 15-year annual installment payment stream. The amendment was consistent with the intent of the original agreement and with the manner in which the agreement operated in practice. The arrangements are designed to provide specified retirement and death benefits to Mr. Nussbaum in addition to those provided under the 401(k) Plan. Plexus’ commitment was funded in fiscal 2002 and prior years. Mr. Nussbaum has received payments under the special retirement arrangements since 2002, including payments of $338,660 for fiscal 2010, $352,742 for fiscal 2011 and $366,853 for fiscal 2012.

The contributions for Mr. Nussbaum’s special retirement arrangement are invested in life insurance policies on his life, which were acquired by Plexus. To the extent that any of the payments constitute excess parachute payments subjecting Mr. Nussbaum to an excise tax, the agreement provides for an additional payment (the “gross-up payment”) to be made by Plexus to him so that after the payment of all taxes imposed on the gross-up payment, he retains an amount of the gross-up payment equal to the excise tax imposed. If Mr. Nussbaum dies prior to receiving all of the 15-year annual installment payments, death benefit payments specified in the arrangement become due.

Stock Ownership Guidelines

Plexus believes that it is important for directors and executive officers to maintain an equity stake in Plexus to further align their interests with those of our shareholders. Directors and executive officers must comply with stock ownership guidelines as determined from time to time by the board. The ownership guidelines for directors currently require that directors must own 5,000 shares of common stock within five years of election or appointment to the board, of which 2,000 shares must be owned within the first year of service. Unexercised stock options (whether or not vested) do not count toward a director’s ownership for purposes of these guidelines. Currently, all of our directors are in compliance with these guidelines. The stock ownership guidelines for executive officers are discussed at “Compensation Discussion and Analysis—Elements and Analysis of Direct Compensation—Equity Ownership Guidelines.”

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Securities Exchange Act of 1934 requires Plexus’ officers and directors, and persons who beneficially own more than 10% of Plexus’ common stock, to file reports of ownership and changes in ownership with the Securities and Exchange Commission. These “insiders” are required by SEC regulation to furnish Plexus with copies of all forms they file under Section 16(a).

All publicly-held companies are required to disclose the names of any insiders who fail to make any such filing on a timely basis within the preceding fiscal year, and the number of delinquent filings and transactions, based solely on a review of the copies of the Section 16(a) forms furnished to Plexus, or written representations that no such forms were required. On the basis of filings and representations received by Plexus, the Company believes that during fiscal 2012 our insiders have complied with all applicable Section 16(a) filing requirements.

COMPENSATION DISCUSSION AND ANALYSIS

The Compensation and Leadership Development Committee (in this section, the “Committee”) of the Plexus board of directors sets general compensation policies for Plexus. The Committee makes decisions with respect to compensation of the Chief Executive Officer and other Plexus executive officers, and grants stock options, restricted stock units (“RSUs”) and other awards. This section discusses the Committee’s executive compensation philosophy and decisions on executive compensation.

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

Executive Summary

Executive Compensation Philosophy, Goals and Process

The Committee’s philosophy is to fairly compensate all employees, including executives, for their contributions to Plexus, appropriately motivate employees to provide value to Plexus’ shareholders and consider the ability of Plexus to fund any compensation decisions, plans or programs. Fair compensation must balance both short-term and long-term considerations and take into consideration competitive 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 inappropriate risk. Finally, the Committee considers Plexus’ financial condition, the conditions in Plexus’ industry and end markets, and the effects of those conditions on Plexus’ sales and profitability in making compensation decisions.

Plexus’ executive compensation program is designed to provide a rational, consistent reward system that:

• attracts, motivates and retains the talent needed to lead a strong global organization;

• drives global financial and operational success that creates shareholder value without encouraging inappropriate risk-taking;

• creates an ownership mindset and drives behaviors that improve Plexus’ performance and maximize shareholder value; and

• appropriately balances Company performance and individual contribution towards the achievement of success.

For a discussion of the Committee’s decision-making process, its use of consultants and the role of Plexus’ executive officers and staff, see “Corporate Governance—Board Committees—Compensation and Leadership Development Committee—Overview of the Compensation Decision-Making Process” above in this proxy statement.

Focus on Growth and Return on Invested Capital

The Committee seeks to maintain a compensation program that aligns executive compensation with creating and maximizing value for our shareholders. The Committee and Company believe that shareholder value is maximized through revenue growth and generating a return on invested capital (“ROIC”) exceeding the Company’s weighted average cost of capital (“WACC”). These metrics together, when achieved, deliver growth and economic profit. The importance of achieving revenue growth and ROIC 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 enduring financial goals of 15% organic revenue growth and an ROIC that exceeds the Company’s WACC by 500 basis points. In fiscal 2012, executive compensation was further weighted toward achieving these goals. The Company’s annual incentive compensation plan uses return on capital employed (“ROCE”), a derivative measure to ROIC that excludes taxes and equity-based compensation costs because these items do not reflect the Company’s operating performance, which is what the plan is designed to reward.

Overview of Executive Compensation and Benefits

Plexus uses the following compensation reward components working together to create competitive compensation arrangements for our executive officers:

Reward Component	Purpose
Base Salary	Base salary is intended to provide compensation which is not “at risk”; however, salary levels and subsequent increases are not guaranteed. Our base salaries are designed to offer regular fixed compensation for the fulfillment of the duties and responsibilities associated with the job roles of our executives and employees. They are also important because they present a starting point for considering compensation when we seek to attract and retain talented individuals.
Annual Incentive	Our annual cash incentive compensation plan, the Variable Incentive Compensation Plan (the “VICP”), is designed to reward employees for the achievement of important corporate financial goals. There is also a small component of the VICP that rewards employees for the attainment of individual and/or team objectives. The opportunity to earn annual cash incentive payments under the VICP provides a substantial portion of compensation that is at risk and that depends upon the achievement of measurable corporate financial goals and individual objectives. As distinguished from equity-based compensation, which is significantly affected by market factors that may be unrelated to our results, the design of the VICP offers incentives based on our direct performance. We use payouts from the VICP to provide further incentives for our executive officers and employees to achieve these corporate financial goals and individual objectives. As it applies to executive officers, the VICP is a sub-plan of the 2008 Long-Term Plan.
Long-Term Incentives	A substantial part of compensation, which is also at risk, is long-term equity-based compensation, typically awarded in the form of stock options and RSUs under the 2008 Long-Term Plan. Our long-term incentives are designed to tie a major part of our key executives’ total compensation opportunities to Plexus’ market performance and the long-term enhancement of shareholder value, as well as encourage the long-term retention of these executives.
Benefits	The health and well-being of our employees and their families is important to us. Therefore, we provide all of our employees in the United States with various benefits, such as health and life insurance. Offering these benefits also assists the Company in attracting, as well as retaining, executive officers and key personnel.
Retirement Plans	The Company maintains retirement plans to help our employees provide for their retirement on a tax-advantaged basis. Offering retirement plans helps the Company to attract and retain qualified employees, as well as meet competitive conditions. One of these retirement plans, the 401(k) Retirement Plan (the “401(k) Plan”), includes a Plexus stock fund as one of its investment choices to permit employees to maintain Plexus ownership if they wish. The Company also provides a supplemental executive retirement plan under which certain executive officers may elect to defer some or all of their compensation and the Company makes additional contributions on their behalf.
Agreements	Only our Chief Executive Officer has an employment agreement, which is intended to help assure the continuing availability of his services over a period of time and protect the Company from competition post-employment. All executive officers have change in control agreements to help assure that they will not be distracted by personal interests in the case of a potential acquisition of Plexus and to assist in maintaining their continuing loyalty.

23

At Plexus’ 2012 annual meeting of shareholders, the Company held a shareholder advisory vote to approve executive compensation. Over 94% of shares voting supported the proposal and, therefore, the advisory resolution regarding executive compensation was approved. Although the vote was non-binding, the Company, the board of directors and the Committee all pay close attention to communications received from shareholders regarding the Company’s executive compensation policies and decisions. The Committee reviewed the results of the vote and considered the high approval rate as an indication that shareholders generally support the Company’s executive compensation philosophy, program and decisions.

Elements and Analysis of Direct Compensation

Overview of Direct Compensation

Plexus uses three primary components of total direct compensation—salary, annual cash incentive payments under the VICP and long-term equity-based awards under the 2008 Long-Term Plan. Each of these components is complementary to the others, addressing different aspects of direct compensation and seeking to motivate employees, including executive officers, in varying ways.

The Committee does not use any specific numerical or percentage test to determine what percentage of direct compensation will be paid in base salary versus the compensation at risk through the VICP or equity-based compensation. However, the Committee believes that a meaningful portion of compensation should be at risk. VICP targets for executive officers other than the CEO ranged from 55% to 70% of base salary in fiscal 2012 with the opportunity to earn cash incentives beyond those levels if company financial goals were exceeded. In the case of the CEO, the potential target compensation at risk as a percentage of base salary was 110%, reflecting his overall greater responsibility for the Company. Long-term incentives for executive officers are in the form of stock options, which contain an inherent amount of risk since no value is received unless there is an appreciation in stock price, and RSUs that vest based on continued service. After determining each element, the Committee also reviews the resulting total compensation to determine that it is reasonable as a whole.

Base salary adjustments and equity awards are generally targeted for implementation in the second quarter of each fiscal year. The Committee believes this timing aligns employee rewards with the Company’s processes to evaluate employees’ performance and forges a strong link between performance and pay.

The resulting total targeted direct compensation mix used for fiscal 2012 for the Chief Executive Officer and the other executive officers named in the Summary Compensation Table herein (the “named executive officers”) is illustrated in the charts below:

Base Salary

Structure. The Company and the Committee review market-based comparisons, peer group analysis and other third-party survey data as reference points for compensation practices as well as sources of comparative information to assist in establishing appropriate base salaries for its executive officers. Through this form of benchmarking, we do not aim for particular numerical or percentage tests as compared to the peer group or the surveys, we generally target base salaries within ranges near market medians of those groups, with adjustments made to reflect individual circumstances. The Committee

24

expects to make determinations of base salary adjustments for our executive officers in December 2012, after it has reviewed and considered the analysis discussed above in “Corporate Governance–Board Committees–Compensation and Leadership Development Committee–Overview of the Compensation Decision-Making Process–Use of Consultants.” The effective date of any base salary adjustment for our executive officers is generally targeted for January in order to be aligned with the Company’s other U.S. salaried employees.

Factors Considered in Determining Base Salary. Prior to establishing base salary increases for the CEO and approving salary levels for other executive officers, the Committee takes into consideration various factors. These factors include compensation data from the proxies of our peer group, salary increase trends for executive base pay and other information provided in published surveys. An in-depth total rewards analysis, including base salary, is completed annually for each executive position using the peer group and survey data as indicated above. The Committee also considers the individual executive officers’ duties and responsibilities and their relative authority within Plexus.

With respect to increases in CEO base salary (as well as other compensation actions that impact our CEO), the Committee uses this input and meets in executive session to discuss appropriate pay positioning and pay mix based on the data gathered. With respect to the other executive officers, the CEO uses similar data and submits his recommendations to the Committee for final determination. The data gathered in the determination process helps the Committee to test for fairness, reasonableness and competitiveness. However, taking into account the compensation policies and goals and a holistic approach to executive compensation packages, the Committee’s final determination may incorporate the subjective judgments of its members as well.

Executive officer base salary increases may include the following two components:

• Competitive Adjustments. If executive officer salaries fall below the competitive median range when we compare them to our peer group and survey data, we consider increasing the salaries to a more competitive level. In some cases these competitive adjustments may take place over a multi-year period and may depend on individual performance.

• Merit Increases. If executive officer salaries are found to be at an appropriate level when we compare them to the peer group and general industry survey data for the position, then a separate merit increase may be provided based on individual performance, if appropriate.

2012 Base Salary Adjustments. Base salary adjustments for fiscal 2012 were approved by the Committee in December 2011. For fiscal 2012, the Committee did not increase our CEO’s base salary, which remained near the intended 50th percentile of peer group and market comparisons. Instead, the Committee placed a greater emphasis on annual and long-term incentive opportunities since they are performance-based, represent compensation that is at risk, promote the creation of shareholder value and are intended to further align the interests of our CEO with those of our shareholders. Our CEO’s base salary is higher than that of our other executive officers because of his more extensive and challenging duties and responsibilities.

Increases for the other executive officers varied from 2.6% to 7.1%; the smaller adjustments reflected merit increases for performance over the past year when salaries were otherwise in line with the market while larger increases represented a combination of competitive adjustments, merit increases and, in certain cases, increases in responsibilities. In addition, Mr. Lim’s compensation and benefits package also reflects regional survey data of the Asian markets. Other variations between the executive officers reflect competitive conditions and the Committee’s view of the executive officers’ duties, responsibilities and performance. The Committee believed that base salaries for our other executive officers were aligned with peer group and market comparisons; therefore, fiscal 2012 base salary percentage increases were generally lower than in previous years. Similar to the adjustments to the compensation package for our CEO noted above, a greater emphasis was placed on annual and long-term incentive opportunities in order to more strongly link executive compensation with Company performance and shareholder returns Presented below are the fiscal 2012 base salaries and percentage increases as compared to fiscal 2011 for our named executive officers:

25

Executive Officer	Fiscal 2012 Base  Salary		Percentage Increase Compared to Fiscal 2011
Mr. Foate	$	800,000	0.0%
Ms. Jones	$	390,000	2.6%
Mr. Buseman	$	370,000	2.8%
Mr. Kelsey	$	340,000	3.0%
Mr. Lim	$	355,000	2.9%

Annual Incentive

Plan Structure. The VICP provides annual cash incentives to approximately 3,400 participants, including our CEO and other executive officers. For executive officers, the VICP is a sub-plan of the 2008 Long-Term Plan. The award opportunity levels for each participant are expressed as a percentage of base salary. For example, in fiscal 2012 the targeted award opportunity for our CEO was 110% of base salary, and the targeted award opportunities for other executive officers varied from 55% to 70% of base salaries; the award opportunities for non-executive officer participants varied from 3% to 45% of base salaries. The targeted award opportunity for our CEO was increased by ten percentage points in fiscal 2012 to better align with peer group and market comparisons, and, in combination with the lack of a base salary increase, to shift a higher portion of his potential compensation toward performance-based elements of our compensation program. Annual incentive opportunity targets for our other executive officers increased by five to ten percentage points in fiscal 2012 as a result of adjustments for market competitiveness and, in certain cases, increases in responsibilities, as well as an increased emphasis on incentive compensation. In addition, offering a greater percentage of compensation at risk was intended to more strongly link executive compensation with Company performance and shareholder returns.

Our CEO and other executive officers also have the opportunity to earn above their targeted award opportunities based on the achievement of corporate financial goals. Higher levels of duties and responsibilities within Plexus lead to higher cash incentive opportunities under the VICP because the Committee believes that the higher the level of responsibility, the more influence the individual can have on corporate performance. In addition, competitive factors make relatively higher reward possibilities important for those positions. For each executive officer, 80% of the targeted award is keyed to the corporate financial goals; the remaining 20% of the targeted award is keyed to the achievement of individual objectives. The table below lists the fiscal 2012 targeted VICP award opportunities for the named executive officers, expressed as a percentage of base salary:

Executive Officer	Fiscal 2012 Targeted Award as  a Percentage of Base Salary
Mr. Foate	110%
Ms. Jones	70%
Mr. Buseman	70%
Mr. Kelsey	70%
Mr. Lim	60%

The VICP provides for payments relating to corporate financial goals both below and over the targeted awards by establishing specific “threshold levels” of corporate performance at which payments begin to be earned and “maximum payout levels” beyond which no further payment is earned. The payout at the “maximum payout level,” which is based solely on achieving the corporate financial goals, is 180% of the targeted award for the CEO and the other executive officers. Payments to participants are not permitted under the VICP unless the Company achieves net income for the plan year.

Under the VICP, the Committee has the authority to adjust results, for example, to reflect acquisitions or unusual gains or charges. No such discretion was used by the Committee in fiscal 2012.

26

2012 Plan Design – Company Goals. The specific corporate financial goals for fiscal 2012, each of which stood independently of the other with regard to award opportunities, were revenue and ROCE. The goals were chosen because they aligned performance-based compensation to the key financial metrics that the Company used internally to measure its ongoing performance and that it used in its financial plans. Our fiscal 2012 targets for these goals were set as part of the annual financial planning process. For each of the corporate financial goals, we also established specific “threshold” and “maximum payout” levels of achievement as part of that process.

For the purposes of the VICP, ROCE is defined as annual operating income before taxes and excluding equity-based compensation costs divided by the five-point quarterly average of Capital Employed during the year. Capital Employed is defined as equity plus debt less cash, cash equivalents and short-term investments. The Company excludes taxes and equity-based compensation costs because these factors do not reflect the operating performance of the Company, which is what the VICP is intended to reward. For the same reasons, the Committee may, at its discretion, exclude restructuring costs and/or non-recurring charges when determining ROCE for VICP awards; no such discretion was exercised by the Committee in fiscal 2012.

No award is paid for any component of the VICP if Plexus incurs a net loss for the fiscal year (excluding non-recurring or restructuring charges and equity-based compensation costs). Awards for performance between the “threshold” level and “target” level are calculated by straight-line interpolation, as are awards between the “target” level and the “maximum payout” level.

For fiscal 2012, in accordance with Plexus’ strategic plan, the Committee set performance levels for each metric with a focus on achieving our enduring financial goals using the philosophy below:

	Threshold	Target	Maximum Payout (Enduring Goals)
Revenue	Growth approximately equal to inflation	Midpoint between threshold and maximum payout	15% revenue growth
ROCE	Equal to Plexus’ WACC plus 300 basis points	Midpoint between threshold and maximum payout	Equal to Plexus’ WACC plus 800 basis points

We believe that setting the maximum payout levels for revenue and ROCE consistent with our enduring financial goals fully aligns employees with financial results that maximize value to our shareholders, without encouraging inappropriate risk-taking. Threshold levels for both metrics were set at the minimum levels of performance at which Plexus believes it begins generating value for our shareholders. Target levels for revenue and ROCE, which were set between the threshold and maximum payout levels, were intended to be challenging, but achievable, based on industry conditions and Plexus’ financial plan.

The following table sets forth the fiscal 2012 financial targets and potential VICP payout amounts (as a percent of targeted VICP cash incentive) for the named executive officers, at the threshold, target and maximum payout performance levels:

	Threshold						Target						Maximum Payout
Component	Goal			Payout			Goal			Payout			Goal			Payout
Revenue (in millions)	$	2,320			0	%	$	2,443			40	%	$	2,566			90	%
ROCE		15.5	%		0	%		18.0	%		40	%		20.5	%		90	%
Individual Objectives					up to 20	%					up to 20	%					up to 20	%
Total Potential Incentive = Revenue + ROCE + Individual Objectives					up to 20	%					up to 100	%					up to 200	%

In fiscal 2012, revenue was $2,306.7 million and ROCE was 18.7%. Therefore, the Company’s performance was below the threshold level for revenue and between the target and maximum payout levels for ROCE; as a result, Plexus paid awards to executive officers and other employees based on ROCE

27

performance only. As a consequence, total payments to executives represented 54.6% versus the target of 80% for corporate financial performance. Plexus’ actual performance in fiscal 2012 as compared to these performance levels is illustrated by the following graphs:

2012 Plan Design – Individual Objectives. Individual participants typically set several individual objectives for the plan year. Some of the individual objectives are shared by multiple executives when they work as part of a team to focus on an objective. Attainment of the individual objectives represents 20% of the potential targeted VICP award; however, no such award may be earned based on individual objectives unless the Company achieves net income for the plan year. The Committee determines and approves the individual objectives established for the CEO. The Committee also reviews and approves, with input from the CEO, the individual objectives established for the other executive officers. The Committee’s assessment of all executive officers’ individual objectives is based on their likely impact on the achievement of the annual financial plan and other longer-term strategic priorities, their effect on shareholder value and their alignment with one another.

Achievement of individual objectives, for which there was a potential payout equivalent to 20% of the “targeted” award, varied among the other named executive officers from 90.3% to 95.5% of the individual’s potential payout for personal objectives, with the CEO achieving 93.2%. These percentages were based upon the Committee’s determination of the degree to which the executive achieved his or her objectives. The CEO provided the Committee with an assessment of the performance of all of the executive officers other than himself and recommended resultant award percentage levels based on the achievement by each executive officer of his or her individual objectives.

The following are summaries of the individual objectives for our named executive officers in fiscal 2012:

• Dean A. Foate: Mr. Foate’s individual objectives related to: designing strategies to support global expansion and to expand the Company’s engineering solutions business; and developing and implementing processes to further strengthen leadership throughout the Company.

• Ginger M. Jones: Ms. Jones’ individual objectives related to: designing strategies for the continued development and deployment of a global information technology (“IT”) platform; developing and implementing strategies to differentiate the Company in the marketplace through the expansion of service capabilities; designing processes and tools to assist with

28

consistently delivering the Company’s stated financial model; and optimizing the Company’s overall cash cycle and improving return on invested capital.

• Michael D. Buseman: Mr. Buseman’s individual objectives related to: designing strategies to support global expansion; developing and implementing strategies to differentiate the Company in the marketplace through the expansion of service capabilities; designing processes and tools to assist with consistently delivering the Company’s stated financial model; and designing strategies to mitigate potential future risks associated with manufacturing operations.

• Todd P. Kelsey: Mr. Kelsey’s individual objectives related to: designing strategies to support global expansion and to expand the Company’s engineering solutions business; developing and implementing strategies to differentiate the Company in the marketplace through the expansion of service capabilities; optimizing the Company’s overall cash cycle and improving return on invested capital; designing processes and tools to assist with consistently delivering the Company’s stated financial model; and designing strategies to mitigate potential future risks associated with manufacturing operations.

• Yong Jin Lim: Mr. Lim’s individual objectives related to: designing strategies to support the expansion of operations in Asia; designing strategies for the continued development and deployment of a global IT platform; designing strategies to ensure ongoing leadership development throughout the Company; developing and implementing strategies to differentiate the Company in the marketplace through the expansion of service capabilities; optimizing the Company’s overall cash cycle and improving return on invested capital; designing processes and tools to assist with consistently delivering the Company’s stated financial model; and designing strategies to mitigate potential future risks associated with manufacturing operations.

Long-Term Incentives

Plan Structure. Total compensation, consistent with practices in our industry, places a particular emphasis on equity-based compensation for executive officers. The shareholder-approved 2008 Long-Term Plan allows for various award types, including options, SARs, restricted stock, RSUs, unrestricted stock awards, performance stock awards and cash incentive awards. Those awards are intended to provide incentives to enhance corporate performance as well as to further align the interests of our executive officers with those of our shareholders. The Committee’s policy is to not “back-date” equity grants and no equity grant was “back-dated” in fiscal 2012. The reported values of the long-term incentive opportunities under equity plans can vary significantly from year to year as a percentage of total direct compensation because they are determined by valuing the equity-based awards on the same basis that we use for financial statement purposes; that value depends significantly on our stock price and its volatility at the time of the awards.

The Committee’s long-term incentive strategy allows for use of a portfolio approach when granting awards. For fiscal 2012 the Committee used, and going forward the Committee intends to continue using, a combination of stock options and RSUs in order to align all long-term incentives with the Company’s overall performance and shareholder returns.

The Committee intends that each element of the portfolio addresses a different aspect of long-term incentive compensation, as set forth below:

• Stock options provide rewards based upon the appreciation in value to shareholders, as measured by the increase in our share price, and there is no value to these awards if our share price does not increase.

• RSUs provide an interest in the value of the Company’s shares, because, even though they vest over time, they provide recipients with a certain equity interest, assuming continued employment. In addition to promoting retention, RSUs further align executives’ interests with the interests of shareholders and provide a long-term ownership mentality as well as motivation to succeed in the

29

long-term because the value of RSUs does not solely depend upon increases in the market price of our shares, which may occur over a short period of time.

• For senior non-executive key employees who are eligible for equity awards, Plexus uses a mix of RSUs and stock-settled stock appreciation rights (“SARs”). Stock-settled SARs provide rewards based upon the appreciation in value to shareholders as measured by the increase in our share price while promoting employee share ownership; stock-settled SARs also allow the Committee to preserve shares available under the plan and minimize dilution. For other non-executive employees eligible for equity awards, Plexus uses RSUs for the reasons noted above.

The allocation formulas used in fiscal 2012 for executive officers and other non-executive employees receiving equity grants are illustrated in the charts below:

Annual Award Determination and Allocation Process. Each year the Committee is presented a recommended total pool of options, stock-settled SARs and RSUs to be awarded to eligible participants. The Committee reviews the estimated cost of the pool and the recommended grant guidelines prior to making grants. Pursuant to its portfolio approach, the Committee distributes the entire value of each grant among the three types of awards—options, stock-settled SARs and RSUs—as shown above. The awards are valued at their Black-Scholes fair-market value when making these determinations. For current executive officers, the Committee uses a distribution formula weighted toward stock options, so as to particularly promote increasing shareholder returns.

The Committee determines the grants for the CEO and other executive officers. The CEO provides the Committee with initial grant recommendations for each executive officer other than himself. The Committee determines the grant value for each executive officer by balancing the need to provide fair compensation with the desire to keep related compensation expense relatively stable from period to period. When making individual grants, the Committee considers each executive officer’s duties, responsibilities and performance. Those in positions with more responsibility tend to receive larger grants to reflect their role in the Company and the market comparisons for their compensation. Also, as discussed above, for the CEO, the Committee uses the vested and unvested equity information, as well as the accumulated value analysis, to balance the level of existing awards with the desire to reward performance and to provide retention incentives.

For fiscal 2012, options for 91,750 shares and 38,000 RSUs were granted to the CEO, and options for 171,000 shares and 71,600 RSUs were granted to the other executive officers as a group. These amounts increased from the fiscal 2011 grant levels as a result of adjustments for market competitiveness. In addition, as mentioned above, in fiscal 2012, the Committee focused on increasing incentive award opportunities for our executive officers as a portion of total potential compensation, rather than approving larger base salary increases, in order to more strongly link executive compensation with Company performance and shareholder returns.

Equity awards are also allocated to high-performing key employees based upon recommendations by executive officers in accordance with a grant range grid, which assigns a range of grant sizes to each employee responsibility level.

30

Basis for Determination of Timing of Grants. The Committee makes quarterly stock option and stock- settled SARs grants rather than annual grants due to the volatility of the stock market and of Plexus’ stock in particular. Granting stock options and SARs all on one date in the year can make the strike price, its related expense, and the opportunity it represents to employees vary significantly in ways that do not necessarily reflect long-term performance of Plexus stock.

The Committee’s formula to support the quarterly grant strategy states that the grant dates will occur three days subsequent to the release of quarterly earnings, not including the day of the release. The Committee uses future dates, as is permitted by the 2008 Long-Term Plan, because that minimizes the opportunity to choose a date based upon market performance known or knowable at the time of determination. The 2008 Long-Term Plan provides that the exercise price of a stock option is not permitted to be less than the fair market value on the stock option grant date. New hire option and stock-settled SAR grant levels are determined at or around the time of hire, and commence on the next quarterly grant date following the date of hire.

Grants of RSUs are generally made once a year during the fiscal second quarter. The Committee did not make any special grants of RSUs to executive officers in fiscal 2012. In fiscal 2009, the Committee made retention-related grants of RSUs to all executive officers other than Mr. Foate, which vested in August 2012. The Committee believes that these grants had their intended retention effect.

2012 Awards. Based on the Committee’s long-term incentive strategy as well as individual responsibility and performance considerations, and reflecting all of the grants discussed above, in fiscal 2012, the Committee made total grants of options and RSUs to the named executive officers as follows:

Executive Officer	Options (#)		RSUs (#)
Mr. Foate		91,750		38,000
Ms. Jones		23,750		10,000
Mr. Buseman		28,750		12,000
Mr. Kelsey		28,750		12,000
Mr. Lim		23,750		10,000

Options vest in two annual increments and grants of RSUs vest on the third anniversary of the grant, all subject to early vesting on a change in control.

Equity Ownership Guidelines. To complement the 2008 Long-Term Plan’s goal of increasing the alignment between the interests of management and shareholders, the Committee adopted executive stock ownership guidelines. These guidelines require our CEO to own Plexus stock with a market value equal to at least three times his annual base salary; executive officers other than our CEO, including the named executive officers in the “Summary Compensation Table” below, are required to own, at a minimum, Plexus stock with a market value equal to one times their annual base salary. There is no specific time requirement to meet these guidelines. However, an executive officer is generally not permitted to sell Plexus shares that were acquired or awarded while an executive officer until the ownership requirement is met; there are exceptions, including financing the exercise of stock options and any applicable taxes when the shares will be held or with prior approval under special circumstances. All executive officers are in compliance with the procedural requirements of the guidelines, while seven of our executive officers, including our CEO, have met the ultimate ownership amounts required by the guidelines.

Clawback Policy. Pursuant to the Plexus Corp. Executive Compensation Clawback Policy, in the event of a material restatement of the Company’s financial results as a result of significant non-compliance with financial reporting requirements, the Committee will review incentive compensation that was paid to the Company’s executive officers under the VICP (or any successor plan thereto) based solely on the achievement of specific corporate financial goals (“covered compensation”) during the period of the restatement. If any covered compensation would have been lower had the covered compensation been calculated based on the Company’s restated financial results, the Committee will, as and to the extent it deems appropriate, recoup any portion of covered compensation paid in excess of what would have been paid based on the restated financial results. The

31

Committee may seek the recovery of covered compensation for up to three years preceding the date on which the Company is required to restate its financial results.

This policy applies in addition to any right of recoupment against the Company’s Chief Executive Officer and Chief Financial Officer pursuant to the Sarbanes-Oxley Act of 2002. The policy does not apply in any situation where a restatement is not the result of significant non-compliance with financial reporting requirements, such as any restatement due to a change in applicable accounting rules, standards or interpretations, a change in segment designations or the discontinuance of an operation.

Anti-Hedging Policy. The Company’s Insider Trading Policy explicitly prohibits directors, officers and employees from engaging in transactions designed to hedge or offset a decrease in the price of the Company’s common stock. Short sales of the Company’s securities are also prohibited under the Insider Trading Policy.

Elements and Analysis of Other Compensation

In addition to direct compensation, Plexus uses several other types of compensation, some of which are not subject to annual Committee action. These include benefits, retirement plans and employment or change in control agreements. These are intended to supplement the previously described compensation methodologies by focusing on long-term employee security and retention. Certain of these plans allow employees to acquire Plexus stock.

Benefits

Structure. We generally provide health and welfare benefits to our executive officers on the same basis as other salaried employees in the United States, although some benefit programs, as discussed elsewhere, are specifically targeted to our executive officers’ specific circumstances. Consistent with competitive practice, the Committee approves certain perquisites and other benefits for our CEO and the other executive officers in addition to those received by all U.S. salaried employees. The other benefits for certain of our executive officers are: a flexible perquisite benefit valued at up to $15,000 per calendar year to be used for expenses such as personal financial planning, spouse travel costs in connection with business-related travel, club memberships and/or tax and estate advice; a company car; and additional life and disability insurance due to the dollar limits of the Company’s disability insurance policies. As a result of local law and custom, different but comparable insurance programs and other benefits may apply to personnel, including Mr. Lim, who are located in countries outside of the United States as well as to executive officers who may be temporarily assigned outside of the United States.

Retirement Planning – 401(k) Plan

Structure. The 401(k) Plan, which is available to substantially all U.S. employees, allows employees to defer a portion of their annual salaries into their personal accounts maintained under the 401(k) Plan. In addition, Plexus matches a portion of each employee’s contributions, up to a maximum of $10,000 per calendar year. Employees have a choice of investment alternatives, including a Plexus stock fund, in which to invest those funds.

Retirement Planning – Supplemental Executive Retirement Plan

Structure. As a consequence of Internal Revenue Code limitations on compensation which may be attributed to tax qualified retirement plans (such as the 401(k) Plan), we have also developed a supplemental executive retirement plan for our executive officers to address their particular circumstances and promote long term loyalty to Plexus until retirement. Plexus’ supplemental executive retirement plan (the “SERP”) is a deferred compensation plan which allows participants to defer taxes on current income. Under this plan, executive officers (other than Mr. Lim), may elect to defer some or all of their compensation. Plexus may also make discretionary contributions. Additionally, Plexus has purchased Company-owned life insurance on the lives of certain executives to meet the economic commitments associated with this plan. The plan allows investment of deferred compensation amounts on behalf of the participants into individual accounts and within these accounts, into one or more designated mutual funds or investments. These investment choices do not include Plexus stock. Deferred amounts and any earnings

32

which may be credited become payable upon termination, retirement from Plexus, or in accordance with the executive’s individual deferral election.

All executive officers, other than Mr. Lim, participate in this program. Additionally, the Company can credit a participant’s account with a discretionary employer contribution. Any employer contributions to the SERP require Board approval. The SERP provides a vehicle for the Company to restore the lost deferral and matching opportunity caused by tax regulation limitations on such deferrals and matched contributions for highly compensated individuals; the Committee believes these limitations make supplemental retirement plans common practice in general industry. The Committee also believes that further retirement compensation through the SERP is appropriate to meet the market for executive compensation and to provide a stronger incentive for executives to remain with Plexus through retirement.

Fiscal 2012 Plan Activity.

• Contribution Formula. Under a funding plan adopted by the Committee, the SERP provides for an annual discretionary contribution of the greater of (a) 9% of the executive’s total targeted cash compensation, minus Plexus’ permitted contributions to the executive officer’s account in the 401(k) Plan, or (b) $13,500. Total targeted cash compensation is defined as base salary plus the targeted annual incentive plan cash incentive at the time of the Company’s contribution.

The Committee adopted this approach for discretionary contributions to reflect competitive practices based on the research, analysis and recommendations of Towers Watson, its compensation consultant for that program. In fiscal 2011, after reviewing the results of a competitive analysis performed by Towers Watson, the Committee increased the Company contribution to its current level in order to be more in line with current market practice.

• Employer Contributions. For fiscal 2012, the total employer contributions to the SERP accounts was $395,840 for all participants as a group, including $139,315 for the CEO. See footnote 4 to the “Summary Compensation Table.”

• Special Contribution. The SERP also allows the Committee to make discretionary contributions over and above the annual contribution noted above. In fiscal 2012, the Committee did not make any such contributions to any of the executive officers, including the named executive officers.

Fiscal 2013 Payment Schedule. The annual contribution made by the Company will be paid throughout the year on a bi-weekly basis. This schedule allows for dollar cost averaging and spreads the expense of the contribution across the fiscal year. If necessary, a true-up payment will be made at the end of the fiscal year if the Company contribution for any executive officer is less than $13,500.

Foreign Retirement Arrangements

Since Mr. Lim is not a United States resident, he does not participate in the SERP or the 401(k) Plan. Rather, he participates in the Employees Provident Fund which is mandated by Malaysian law. Under law, minimum contributions of 12% of an employee’s wages (salary plus bonus) are required to be made by an employer; Plexus chose to make a contribution of 17% in fiscal 2012 in Mr. Lim’s case since it is Plexus’ practice in Malaysia to make higher contributions than the statutory minimum for personnel with relatively high levels of seniority and responsibility.

Employment and Change in Control Agreements

Structure. We do not generally have employment agreements with our executive officers; however, Plexus does maintain an employment agreement with our Chief Executive Officer in order to recognize the importance of his position, to help assure Plexus of continuing availability of Mr. Foate’s services over a period of time, and to protect the Company from competition post-employment. All executive officers and certain other key employees have change in control agreements (with the exception of Mr. Foate, who has change in control provisions as part of his employment agreement), to both help assure that executive officers will not be distracted by personal interests in the case of a potential acquisition of Plexus as well as

33

to maintain their continuing loyalty. We also believe that competitive factors require us to provide these protections to attract and retain talented executive officers and key employees.

Mr. Foate’s employment agreement is described below in “Executive Compensation – Employment Agreements and Potential Payments Upon Termination or Change in Control – Mr. Foate’s Employment Agreement.” The change in control agreements with our executive officers (with the exception of Mr. Foate) are described below in “Executive Compensation – Employment Agreements and Potential Payments upon Termination or Change in Control – Change in Control Arrangements.” Please refer to those discussions for a further explanation of those agreements.

Determination of Benefit Levels. In general, the change in control agreements with executive officers provide that, upon termination in the event of a change in control, executive officers will receive compensation equaling three times annual salary plus targeted bonus, a continuation of health and retirement benefits for that period, and a gross-up payment for excise taxes. In addition, under the 2008 Long-Term Plan (and its predecessor) upon a change in control, all unvested awards will automatically vest for all award holders. Certain other key employees also have change in control agreements on substantially the same terms, although generally with only one or two years’ of coverage. In determining which employees should have change in control agreements, the Committee utilizes its guidelines, which focus on position, responsibilities and compensation level in order to minimize subjectivity.

The Committee reviews the benefit levels under these agreements annually. It is the Committee’s view that the level of benefits, combined with the “double trigger” requiring both a change in control and a termination of employment, provides an appropriate balancing of the interests of the Company, its shareholders and its executives. Benefit levels are believed to be both in line with competitive standards and Plexus’ overall compensation policy and level of other benefits, as well as necessary and appropriate to attract and retain executive talent. The Committee believes it is general market practice to provide that unvested awards will vest on a change in control, which is the case under the 2008 Long-Term Plan (and its predecessor), as approved by Plexus’ shareholders. Therefore, offering a package that is consistent with market practices, is appropriate to help motivate executives to focus on the Company’s shareholders, even when the circumstance might jeopardize their employment. The Committee also intends that the potential expense of the agreements is reasonable as compared to total enterprise value. The Committee estimated that the agreements represented approximately 3.0% of the average of fiscal 2007 and fiscal 2006 total enterprise value at the time they were adopted; potential expense was estimated at 3.7% of total enterprise value as of the date of the Committee’s most recent determination. As noted above, the agreements contain a “double trigger,” which provides that benefits would only be paid to the executive officers in the event of a substantial impact upon their employment and compensation.

The Committee periodically reviews the scope and context of the change in control agreements. The Committee continues to believe, as noted above, that the change in control agreements will help motivate the executive officers to respond appropriately, for the benefit of the Company and its shareholders, in the case of a proposed acquisition of the Company which they might perceive would jeopardize their employment.

Tax Aspects of Executive Compensation

The Committee generally attempts to preserve the tax deductibility under the Internal Revenue Code (the “Code”) of all executive compensation. However, at times and under certain circumstances, it believes that it is more important to provide appropriate incentives irrespective of tax consequences.

Section 162(m) of the Code generally limits the corporate tax deduction for compensation paid to the executive officers that is not “performance-based” to $1 million annually per executive officer. Plexus has taken action with respect to the provisions of Section 162(m) so that compensation income relating to stock options, SARs, performance-based restricted stock and cash incentive awards, including those made to executive officers pursuant to the VICP, under the 2008 Long-Term Plan (and predecessor plans) is exempt. Compensation under these shareholder approved plans that is performance-based is generally not subject to the $1 million limitation; however, the grant of restricted shares without performance goals would not be considered to be performance-based and therefore would be subject to the limit along with cash salaries and bonuses. As a result of the shareholders’

34

approval of the 2008 Long-Term Plan (and its predecessor), the Committee believes that most compensation income under these plans (other than any awards in the future of restricted stock or RSUs without performance goals, as is the case for time vested RSUs) would not be subject to the Code’s deduction limitation. However, if such restricted stock awards are made, the covered compensation of some individuals could exceed $1 million and, in those cases, the excess would not currently be tax deductible, as was the case in fiscal 2012.

Other provisions of the Code also can affect the decisions which we make. Section 280G of the Code imposes a 20% excise tax upon executive officers who receive “excess” payments upon a change in control of a publicly-held corporation to the extent the payments received by them exceed an amount approximating three times their average annual compensation. The excise tax applies to all payments over one times average annual compensation. Plexus would also lose its tax deduction for “excess” payments. Our change in control agreements provide that benefits under them will be “grossed up” so that we also reimburse the executive officer for these tax consequences. Although these gross-up provisions and loss of deductibility would increase Plexus’ tax expense, the Committee believes it is important that the effects of this Code provision not negate the protections which it provides by means of the agreements.

The Code also provides a surtax under Section 409A, relating to various features of deferred compensation arrangements of publicly-held corporations for compensation deferred after December 31, 2004. Section 409A became fully effective on January 1, 2009. We conducted an extensive review of our benefit plans and employment arrangements to help assure they comply with Section 409A and that there are no adverse effects on Plexus or our executive officers as a result of these Code amendments. We made various changes to some of these plans and arrangements to ensure full compliance with the rules under Section 409A; however, we do not expect these changes to have a material tax or financial consequence on Plexus.

COMPENSATION COMMITTEE REPORT

The duties and responsibilities of the Compensation and Leadership Development Committee of the board of directors are set forth in a written charter adopted by the board, as set forth on the Company’s website as described above under “Corporate Governance—Board Committees—Compensation and Leadership Development Committee.” The Committee reviews and reassesses this charter annually and recommends any changes to the board for approval.

As part of the exercise of its duties, the Committee has reviewed and discussed with management the above “Compensation Discussion and Analysis” contained in this proxy statement. Based upon that review and those discussions, the Committee recommended to the board of directors that the Compensation Discussion and Analysis be incorporated by reference in Plexus’ annual report to shareholders on Form 10-K and included in this proxy statement.

SUMMARY COMPENSATION TABLE

The following table sets forth a summary of the compensation which we paid for fiscal 2012 to our Chief Executive Officer, our Chief Financial Officer and the three executive officers who had the highest compensation of our other executive officers (collectively, the “named executive officers”). More detailed information is presented in the other tables and explanations which follow the following table.

(1) Includes amounts voluntarily deferred by the named persons under the Plexus Corp. 401(k) Retirement Plan (the “401(k) Plan”), the Plexus supplemental executive retirement plan (the “SERP”) and, for Mr. Lim, the Malaysian Employees Provident Fund. The amounts deferred under the SERP are also included in the “Executive Contributions in Last FY” column of the “Nonqualified Deferred Compensation” table below.

(2) Both the “Bonus” and the “Non-Equity Incentive Plan Compensation” columns represent amounts that were earned during fiscal 2012, fiscal 2011 and fiscal 2010, respectively, under our Variable Incentive Compensation Plan (“VICP”). Under the VICP, annual cash incentives for executive officers are determined by a combination of the degree to which Plexus achieves specific pre-set corporate financial goals during the fiscal year and individual objectives. To the extent a payment was based on individual objectives in fiscal 2010, it is in the “Bonus” column. To the extent that the cash incentive resulted from corporate financial performance, and, for fiscal 2012 and fiscal 2011, individual objectives, that portion of the cash incentive is included under the “Non-Equity Incentive Plan Compensation” column. We include more information about the VICP under “Grants of Plan-Based Awards” below. The amounts shown in the “2012” row were earned in fiscal 2012 but will be paid in fiscal 2013, the amounts shown in the “2011” row were earned in fiscal 2011 and were paid in fiscal 2012, and the amounts shown in the “2010” row were earned in fiscal 2010 and were paid in fiscal 2011. The amounts in the “Non-Equity Incentive Plan Compensation” column for fiscal 2010 also include the value

36

of long-term cash awards granted in that year, which vest on the third anniversary of their respective grant dates; no equivalent grants were made for fiscal 2012 or fiscal 2011.

(3) This column represents the grant date fair value computed in accordance with Accounting Standards Codification Topic 718 (“ASC 718”) of stock and option awards granted in fiscal 2012, fiscal 2011 and fiscal 2010 under the 2008 Long-Term Plan, which are explained further below under “Grants of Plan-Based Awards.” These awards are not subject to performance conditions. Generally accepted accounting principles (“GAAP”) require us to recognize compensation expense for stock options and other stock-related awards granted to our employees and directors based on the estimated fair value of the equity instrument at the time of grant. Compensation expense is recognized over the vesting period. The assumptions that we used to determine the valuation of the awards are discussed in footnote 10 to our consolidated financial statements. Please also see the “Grants of Plan-Based Awards” table below for further information about the stock and option awards granted in fiscal 2012, and the “Outstanding Equity Awards at Fiscal Year End” table below relating to all outstanding stock and option awards at the end of fiscal 2012.

(4) The amounts listed under the column entitled “All Other Compensation” in the table include Company contributions to the 401(k) Plan and the SERP (for Mr. Lim, this represents the Company’s contribution to the Malaysian Employees Provident Fund), reimbursement made by Plexus under its executive flexible perquisite benefit, the value of the company car benefit provided to the executive, additional life and disability insurance coverage and benefits related to an overseas assignment. Per person detail is listed in the table below:

	Year		Company Matching Contribution to 401(k) Plan		Company Contribution to SERP		Executive Flexible Perquisite Benefit		Company Car Benefit		Additional Life and Disability Insurance		Overseas Assignment		Total

Under the executive flexible perquisite benefit, executive officers may be reimbursed for expenses up to $15,000 in a calendar year for miscellaneous expenses such as personal financial planning, spouse travel costs in connection with business-related travel, club memberships and/or tax and estate advice. This benefit is not grossed up for taxes. The amounts in the “Executive Flexible Perquisite Benefit” column above include the reimbursements under that program in the fiscal years listed; these amounts may exceed the calendar year limits due to the difference between the fiscal and calendar year.

Ms. Jones was on a temporary assignment for Plexus in Malaysia for a portion of fiscal 2011. The amount reported above in the “Overseas Assignment” column reflects benefits related to this assignment beyond those that were integral and necessary to the business purpose of the assignment, including expenses for a rental car for her spouse, as well as the related tax gross-up, and a $15,000 overseas allowance, which amount was not grossed up for taxes.

GRANTS OF PLAN-BASED AWARDS

2012

The following table sets forth information about stock and option awards that were granted to the named executive officers in fiscal 2012 under the 2008 Long-Term Plan, as well as information about the potential cash incentive awards dependent on quantifiable corporate performance and individual goals that those executive officers could earn for fiscal 2012 performance (to be paid in fiscal 2013) under the VICP. As a result of fiscal 2012 corporate performance, cash incentive awards based on these criteria were earned in 2012, as set forth under the “Non-Equity Incentive Compensation” column in the “Summary Compensation Table” above. We provide further information about both potential compensation under the VICP and awards under the 2008 Long-Term Plan in fiscal 2012 in the table below, and additional information about those plans following the table.

* Represents a potential cash incentive payment for fiscal 2012 at various performance levels under the VICP (amounts in the “Maximum” column correspond to the “maximum payout level” under the VICP); other grants are stock options and restricted stock units (“RSUs”) under the 2008 Long-Term Plan. As a result of Plexus’ actual performance in fiscal 2012, overall cash incentive awards were earned based on corporate financial performance between the threshold and target levels, as reflected in the “Summary Compensation Table” and discussed in “Compensation Discussion and Analysis” above.

(1) Amounts in the rows labeled “VICP*” reflect potential cash incentive payments that depend on Plexus meeting corporate financial goals and the named executive officers achieving individual objectives (assuming such officers do not meet any of their individual objectives at “Threshold” and meet them fully at both “Target” and

38

the “maximum payout level”). The amounts in the “Threshold” column indicate a payment for performance just above the threshold; there is no minimum payment once the threshold has been exceeded.

(2) Options were granted at the average of the high and low trading prices on the date of grant. Pursuant to the 2008 Long-Term Plan, fair market value may be determined as the average of the high and low trading prices on the date of grant or as an average for a short period of time prior to the grant. The stock options that were granted in fiscal 2012 under the 2008 Long-Term Plan vest over a two year period, with 50% of the options vesting on the first anniversary of their grant date and the remainder vesting on the second anniversary.

(3) The RSUs vest on January 23, 2015, assuming continued employment. See the discussions below under the caption “2008 Long-Term Plan.”

VICP

The VICP (as it applies to our executive officers) is a sub-plan of the 2008 Long-Term Plan. Under the VICP, our executive officers may earn cash incentive awards that depend in substantial part upon the degree to which Plexus achieves corporate financial goals, which are set by our Compensation and Leadership Development Committee (the “Committee”) shortly after the beginning of our fiscal year. As long as Plexus achieves net income for the plan year, each executive officer also may earn a portion of his or her cash incentive award by accomplishing the individual objectives set for that executive officer. These awards are intended to reflect, in each instance, an individual’s performance that may not be reflected in the financial performance of the entire Company. The amounts included in the table are potential future payouts under non-equity incentive awards that could be earned pursuant to both corporate financial and individual goals under the VICP. The amounts in the columns represent, respectively, the amount which could be earned in the event minimum results were achieved so as to result in a threshold payment to the executive officer, the amounts which could be received if each performance target was met exactly at the targeted level and the maximum amount that could be earned under the VICP, which is known as the “maximum payout level.” As noted above, the potential payouts reported in the table assume that the named executive officers do not meet any of their individual objectives at threshold and achieve them fully at both target and the maximum payout level.

Actual Company performance in fiscal 2012 was below the threshold level for revenue and between the target and maximum payout levels for return on capital employed (“ROCE”); therefore, total cash incentives based on corporate financial goals (which, for fiscal 2012, were only paid based on ROCE performance) were paid between the threshold and target levels, as reported in the “Non-Equity Incentive Compensation” column in the “Summary Compensation Table” above.

The maximum amount that could be earned based on individual performance was $171,692 for Mr. Foate (which would have been 20% of his cash incentive award at the targeted levels) and varied from $41,578 to $52,177 for the other named executive officers (also representing 20%).

2008 Long-Term Plan

Under the 2008 Long-Term Plan, the Committee may grant directors, executive officers and other officers and key employees of Plexus stock options, stock-settled SARs, restricted stock, which may be designated as restricted stock awards or RSUs, unrestricted stock awards, performance stock awards (which may be settled in cash or stock) and cash incentive awards in periodic grants. As a result of the volatility of the stock market in recent years, particularly for Plexus stock, the Committee makes, and anticipates continuing to make, quarterly option grants. This grant schedule facilitates overall compensation planning near the beginning of the fiscal year, as the total target amounts for grants for a year are set at that time; the specific dates of each grant are determined in advance. Option grants must be at the fair market value of the underlying shares when the grant is made.

The Committee grants RSUs under the 2008 Long-Term Plan. In fiscal 2012, annual grants were made in January 2012, and vest three years from the date of the grant, assuming continued employment. Going forward, the Committee anticipates continuing to make grants of RSUs in the second quarter of each fiscal year.

(1) Option award granted under the 2008 Long-Term Plan or a predecessor plan. All options have an exercise price equal to the market price of our common stock on the date of grant. Since 2005, the market price has been determined using the average of the high and low trading prices on the grant date. Prior to that date, the market price was determined by an average of the high and low trading prices over a period of five to ten trading days prior to the grant date. Options granted in fiscal 2007 and after vest one-half on each of the first two anniversaries of the grant date.

(2) Based on the $30.29 per share closing price of a share of our common stock on September 28, 2012, the last trading day of fiscal 2012.

(3) Consists of RSUs awarded in fiscal 2010 under the 2008 Long-Term Plan. The RSUs vest on January 25, 2013, based on continued service through that date. See “Compensation Discussion and Analysis—Elements and Analysis of Direct Compensation—Long-Term Incentives” for additional information regarding awards.

(4) Consists of RSUs awarded in fiscal 2011 under the 2008 Long-Term Plan. The RSUs vest on January 24, 2014, based on continued service through that date. See “Compensation Discussion and Analysis—Elements and Analysis of Direct Compensation—Long-Term Incentives” for additional information regarding awards.

(5) Consists of RSUs awarded in fiscal 2012 under the 2008 Long-Term Plan. The RSUs vest on January 23, 2015, based on continued service through that date. See “Compensation Discussion and Analysis—Elements and Analysis of Direct Compensation—Long-Term Incentives” for additional information regarding awards.

NONQUALIFIED DEFERRED COMPENSATION

2012

Plexus does not maintain any defined benefit pension plans. Plexus’ only retirement savings plans are defined contribution plans: the 401(k) Plan for all qualifying U.S. employees; and the supplemental executive retirement plan (the “SERP”) for executive officers (other than Mr. Lim, as described below). Because these are defined contribution plans, Plexus’ obligations are fixed at the time contributions are made, rather than Plexus being liable for future potential shortfalls in plan assets to cover the fixed benefits that are promised in defined benefit plans.

The 401(k) Plan is open to all U.S. Plexus employees meeting specified service and related requirements. Under the plan, employees may voluntarily contribute up to 75% of their annual compensation, up to a maximum Internal Revenue Code (the “Code”) mandated limit of $17,000 ($22,500 if age 50 or older) in calendar year 2012; Plexus will match 100% of the first 4.0% of salary which an employee defers, up to $10,000 in calendar year 2012. There are several investment options available to participants under the 401(k) Plan, including a Plexus stock fund.

Plexus maintains the SERP as an additional deferred compensation mechanism for its executive officers; the individuals covered in fiscal 2012 include Ms. Jones and Messrs. Foate, Buseman and Kelsey. Mr. Lim does not participate because he is not a United States resident. Under the SERP, an executive may elect to defer some or all of his or her compensation through the plan, and Plexus may credit the participant’s account with a discretionary employer contribution. Participants are entitled to the payment of deferred amounts and any earnings which may be credited thereon upon termination or retirement from Plexus, subject to the participants’ deferral elections and Section 409A of the Code. The plan allows investment of deferred compensation held on behalf of the participants into individual accounts and, within these accounts, into one or more designated mutual funds or investments. These investment choices do not include Plexus stock.

Executive officers, including the named executive officers, did not make any personal voluntary deferrals to the SERP for fiscal year 2012. The plan also allows for discretionary Plexus contributions. As discussed in “Compensation Discussion and Analysis—-Elements and Analysis of Other Compensation—Retirement Planning - Supplemental Executive Retirement Plan,” in fiscal 2011, the Committee approved an increase in the Company contribution to the SERP after reviewing a competitive analysis prepared by Towers Watson. As a result, the discretionary contribution is the greater of (a) 9% of the executive’s total targeted cash compensation, minus Plexus’ permitted contributions to the executive officer’s account in the 401(k) Plan, or (b) $13,500. The Committee may also choose to make additional or special contributions; no such contributions were made in fiscal 2012.

Mr. Lim does not participate in these plans because he is a resident of Malaysia and is covered by a different system. Under Malaysian law, an employer must make a contribution to the fund of at least 12% of every employee’s salary during the year to the Employees Provident Fund, which is a retirement savings program established under Malaysian law. In accordance with its practice in Malaysia, Plexus made a contribution of 17% for Mr. Lim to reflect his seniority and responsibilities.

The following table includes information as to contributions under the SERP or, in the case of Mr. Lim, the Malaysian Employees Provident Fund. Since the 401(k) Plan is a tax-qualified plan generally available to all employees, contributions on behalf of the executive officers and earnings in that plan are not included in this table; however, company contributions under both are among the items included in the “All Other Compensation” column in the “Summary Compensation Table” above.

(2) Mr. Lim’s information relates to the Malaysian Employees Provident Fund.

(3) “Aggregate Earnings in Last FY” represent dividends declared by the Malaysian Employees Provident Fund Board for calendar year 2011. This information is not yet available to Mr. Lim or the Company from the Malaysian Employees Provident Fund for calendar year 2012.

(4) Mr. Lim’s fund account also includes contributions prior to his employment with Plexus and related earnings since the Malaysian Employees Provident Fund is not an employer-sponsored plan. The balance also reflects changes in currency exchange rates between the Malaysian ringgit and the U.S. dollar.

EMPLOYMENT AGREEMENTS AND POTENTIAL PAYMENTS UPON TERMINATION OR

CHANGE IN CONTROL

In this section, we are providing information about specific agreements with our executive officers relating to employment and their post-employment compensation. As discussed further below, only Mr. Foate has an employment agreement. All of our executive officers have change in control agreements which will provide, in certain circumstances, for payments to the executive officers in the event of a change in control of Plexus.

Mr. Foate’s Employment Agreement

Plexus does not generally have employment agreements with its executive officers. However, when Mr. Foate became Plexus’ Chief Executive Officer in 2002, the Committee and the board believed it was important to enter into an employment agreement with Mr. Foate to set forth the terms of his employment and to provide incentives for him to continue with the Company over the long term. The Company entered into a new employment agreement with Mr. Foate in 2008. The new employment agreement, which was approved by the Committee and the board, amended and superseded Mr. Foate’s previous employment agreement with the Company. Changes were made in order to more fully comply with changes made to Code Section 409A and to integrate the change in control provisions into the employment agreement; however, the benefits payable under the new agreement are substantially unchanged from those under the previous agreements.

Mr. Foate’s employment agreement is for an initial term of three years and automatically extends (unless terminated) by one year every year, so that it maintains a rolling three-year term. The agreement specifies when Plexus may terminate Mr. Foate for cause, or when Mr. Foate may leave the Company for good reason, and determines the compensation payable upon termination. The definition of “cause” and “good reason” are substantially similar to those under the change in control agreements, as described below, although “good reason” would also include a failure of Plexus to renew the employment agreement. If Mr. Foate is terminated for cause or voluntarily leaves without good reason, dies or becomes disabled, or the agreement is not renewed, Plexus is not

45

required to make any further payments to Mr. Foate other than with respect to obligations accrued on the date of termination. If Plexus terminates Mr. Foate without cause, or he resigns with good reason, Mr. Foate is entitled to receive compensation including his base salary for a three year period following his separation date, a pro-rated VICP cash incentive award keyed to the actual attainment of performance targets for the year in which Mr. Foate is involuntarily terminated, and certain lump sum payments designed to ensure that his benefits approximate those provided under the previous employment agreement. The lump sum payments are equal to the sum of one hundred percent (100%) of Mr. Foate’s annual base salary prior to his separation date and the maximum amount of Company contributions for a full plan year under the 401(k) Plan and the Company’s deferred compensation plans. Mr. Foate would also be eligible to participate in the Company’s medical, dental and vision plans, subject to his payment of any premiums required by such plans, for a three year period following his separation from Plexus. Any payments triggered by a termination of employment are to be delayed until six months after termination, as required by Section 409A of the Code.

Change in control provisions are included in Mr. Foate’s current employment agreement and are substantially identical to those provided in the change in control agreements described below under the caption “Change in Control Agreements,” with Mr. Foate’s payment amount being three times the relevant salary plus benefits.

Under Mr. Foate’s employment agreement, Plexus is also protected from competition by Mr. Foate after his employment with Plexus would cease. Upon termination, Mr. Foate agrees to not interfere with the relationships between the customers, suppliers or employees of Plexus for two years, and that he will not compete with Plexus over the same period and in geographical locations proximate to Plexus’ operations. Further, Mr. Foate has agreed to related confidentiality requirements after the termination of his employment.

Under the 2008 Long-Term Plan and predecessor plans, optionholders (or their representatives) have a period of time in which they may exercise vested stock options after death, disability, retirement or other termination of employment, except in the case of termination with cause. Options do not continue to vest after termination except for full vesting upon a change in control or, when provided in related option agreements, upon death or disability. See “Outstanding Equity Awards at Fiscal Year End” above for information as to Mr. Foate’s outstanding stock options at September 29, 2012. Mr. Foate would also receive accrued and vested benefits under the 401(k) Plan and the SERP, and payment for accrued but unused vacation, upon a termination of employment for any reason; those amounts are not included in “Potential Benefits Table” below. See “Nonqualified Deferred Compensation” above for further information.

Change in Control Agreements

Plexus has change in control agreements with Ms. Jones and Messrs. Buseman, Kelsey and Lim, and its other executive officers (with the exception of Mr. Foate as described above under the caption “Mr. Foate’s Employment Agreement”) and certain other key employees. Under the terms of these agreements, if there is a change in control of Plexus, as defined in the agreement, the executive officers’ authorities, duties and responsibilities shall remain at least commensurate in all material respects with those prior to the change in control. Their compensation may not be reduced. Their benefits must be commensurate with those of similarly situated executives of the acquiring firm, and their location of employment must not be changed significantly as a result of the change in control.

Within 24 months after a change in control, in the event that any covered executive officer is terminated other than for cause, death or disability, or an executive officer terminates his or her employment with good reason, Plexus is obligated to pay the executive officer, in a cash lump sum, an amount equal to three times (one to two times for other key employees) the executive officer’s base salary plus targeted cash incentive payment, and to continue retirement payments and certain other benefits. The change in control agreements designate three times salary plus benefits for each of Ms. Jones and Messrs. Buseman, Kelsey and Lim. The agreements further provide for payment of additional amounts which may be necessary to “gross-up” the amounts due to such executive officer in the event of the imposition of an excise tax upon the payments. The agreements do not preclude termination of the executive officer, or require payment of any benefit, if there has not been a change in control of Plexus, nor do they limit the ability of Plexus to terminate these persons thereafter for cause. It is the Committee’s view that the level of benefits, combined with the “double trigger” requiring both a change in control and a termination of employment, provides an appropriate balancing of the interests of the Company, its shareholders and its executives.

46

Under our change in control agreements:

• A termination for a “cause” would occur if the executive officer willfully and continually fails to perform substantial duties or willfully engages in illegal conduct or gross misconduct which injures Plexus.

• After a change in control, an executive may terminate for “good reason” which would include: requiring the executive to perform duties inconsistent with the duties provided under his or her agreement; Plexus not complying with provisions of the agreement; the Company requiring the executive to move; or any attempted termination of employment which is not permitted by the agreement.

• A change in control would occur in the event of a successful tender offer for Plexus, other specified acquisitions of a substantial portion of the Company’s outstanding stock, a merger or other business combination involving the Company, a sale of substantial assets of the Company, a contested director’s election or a combination of these actions followed by any or all of the following actions: change in management or a majority of the board of the Company or a declaration of a “change in control” by the board of directors.

Also, under the 2008 Long-Term Plan and predecessor plans, award holders (or their representatives) have a period of time in which they may exercise vested awards after death, disability, retirement or other termination of employment, except in the case of termination with cause. Awards do not continue to vest after termination, except for full vesting upon death or permanent disability when provided in the related award agreements or upon a change in control. See “Outstanding Equity Awards at Fiscal Year End” above for information as to executive officers’ outstanding stock options at September 29, 2012 (the named executive officers do not hold any stock-settled SARs). Executives would also receive accrued and vested benefits under the 401(k) Plan and the SERP, and payment for accrued but unused vacation, upon a termination of employment for any reason; those amounts are not included in the table. See “Nonqualified Deferred Compensation” above for further information.

Plexus does not have employment agreements with its executive officers other than Mr. Foate. It also does not have a formal severance plan for other types of employment termination, except in the event of a change in control as described above. Although Plexus has a general practice of providing U.S. salaried employees with two weeks’ severance pay for every year worked (generally to a maximum of 13 weeks) in the case of termination without cause, actual determinations are made on a case-by-case basis. Therefore, whether and to what extent Plexus would provide severance benefits to the named executive officers, or other executive officers, upon termination (other than due to death, permanent disability or a change in control) would depend upon the facts and circumstances at that time. As such, we are unable to estimate the potential payouts under other employment termination scenarios.

Potential Benefits Table

The following table provides information as to the amounts which will be payable (a) to Mr. Foate under his employment agreement if he is terminated by Plexus for cause or without cause, (b) to the named executive officers in the event of death or permanent disability, and (c) to the named executive officers in the event they were terminated without cause, or the executive terminated with good reason, in the event of a change in control. The payments are calculated assuming a termination as of September 29, 2012, the last day of our previous fiscal year. The table includes only benefits that would result from death or permanent disability, a termination or a change in control, not vested benefits that are payable irrespective of a change.

(1) This amount represents payments relating to the executives’ base salary and VICP cash incentive awards to the extent they would be paid after termination, based on the salary in effect at the end of fiscal 2012 and the target VICP cash incentive payment for 2012. Under the change in control agreements, this payment equals three years salary, as it was in effect at the time of termination, plus three times the targeted VICP compensation for the year of termination. There are similar provisions for a termination without cause in Mr. Foate’s employment agreement.

(2) All outstanding unvested stock options would become vested upon a change in control, and the unvested options also would vest upon death or disability. Certain outstanding unvested stock options had no immediately realizable value because the respective exercise prices were higher than $30.29, the closing price of Plexus’ common stock on September 28, 2012, the last trading day of fiscal 2012. See “Outstanding Equity Awards at Fiscal Year End” for further information regarding all stock options owned by the named executive officers, including those that have already fully vested.

(3) All outstanding RSUs and long-term cash awards would become vested upon a change in control. The amount shown represents the difference in value of the unvested RSUs and long-term cash awards between their grant price and market price, based on Plexus’ closing stock price of $30.29 per share on September 28, 2012, the last trading date of fiscal 2012. Grants of long-term cash awards were discontinued after fiscal 2010 in order to align all long-term incentives with the Company’s overall performance and the interests of shareholders.

48

(4) Under the change in control agreements, the Company would be required to continue payments to the 401(k) Plan and SERP for three years at the same level during the year preceding the change in control. There are similar provisions for a termination without cause in Mr. Foate’s employment agreement. This column represents the total amount of those payments. The executive officers would also receive accrued and vested benefits under the 401(k) Plan and the SERP, and payment for accrued but unused vacation, upon a termination of employment for any reason; those amounts are not included in the table. See “Nonqualified Deferred Compensation” for further information.

(5) These amounts include continuing payments of health and welfare benefits, accrued vacation, executive reimbursement plan expenses, company car and other benefits for three years, as provided in the agreement.

(6) In the event of a change in control in Plexus, the change in control agreements with our executive officers provide that we will pay them an additional benefit to reimburse the “golden parachute” excise taxes which they would owe pursuant to Internal Revenue Code Section 280G. This column provides an estimate of these payments, reflecting each executive’s base compensation under Section 280G. Based on Mr. Foate’s average annual compensation and the manner in which Section 280G operates, he would have not qualified for such payments had there been a change in control on September 29, 2012, but could be eligible to receive these payments in future years.

(7) Excludes life or disability insurance payments from third party insurers.

COMPENSATION AND RISK

During fiscal 2012, the Company reviewed its compensation policies, programs and procedures, including the incentives they create and mitigating factors that may reduce the likelihood of excessive risk taking, to determine whether they present a significant risk to the Company. Management assessed risk factors associated with specific compensation programs, as well as enterprise-level compensation risk factors, and a risk rating was assigned to each factor. The program-specific risk factors assessed included payout potential, payout as a percentage of total compensation, risk of manipulation, discretion to modify awards, overall plan design and market appropriateness. Enterprise-level risk factors evaluated included the balance between performance rewarded and the sustainability of that performance, the overall compensation mix, consistency between annual and long-term objectives as well as metrics, achievability of performance goals without undue risk-taking, the relationship of long-term awards to the Company’s pay philosophy, stock ownership requirements, the weighting and duration of performance metrics, the value of severance packages, the degree to which pay programs (including retirement benefits) and/or grants may be considered disproportionate, and the interaction of compensation plans with the Company’s financial performance and strategy. The Compensation and Leadership Development Committee reviewed management’s evaluation process as well as its results, and determined that both the process and conclusions reached were reasonable.

Based on this review, the Company has concluded that its compensation policies, programs and procedures are not reasonably likely to have a material adverse effect on the Company.

ADVISORY VOTE ON EXECUTIVE COMPENSATION

Under the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (the “Dodd-Frank Act”), publicly-traded companies like Plexus are required to hold an advisory vote of their shareholders at least once every three years to approve the compensation of named executive officers, as disclosed in the company’s proxy statement pursuant to the SEC’s Regulation S-K Item 402; Plexus discloses those items in “Compensation Discussion and Analysis” and “Executive Compensation” herein. Plexus currently holds these votes annually.

As described in “Compensation Discussion and Analysis” above, we design our executive compensation programs to attract, motivate and retain the talent needed to lead a strong global organization, to drive global financial and operational success, to create an ownership mindset and to appropriately balance Company performance and individual contributions towards the achievement of success. A meaningful portion of our executive officers’ compensation is at risk, reflecting the Company’s emphasis on pay that reflects performance and drives long-term shareholder value. We believe the Company’s compensation program as a whole is well suited to promote the Company’s objectives in both the short and long term.

Accordingly, the following resolution will be submitted to our shareholders for approval at the annual meeting:

“RESOLVED, that the compensation paid to the Company’s named executive officers, as disclosed pursuant to Item 402 of Regulation S-K, including the Compensation Discussion and Analysis, compensation tables and narrative discussion, is hereby approved.”

As an advisory vote, this proposal is not binding on the Company. However, the Compensation and Leadership Development Committee, which is responsible for designing and administering the Company’s executive compensation programs, values the opinions expressed by our shareholders, and will consider the outcome of the vote when making future compensation decisions on the Company’s executive compensation programs.

The board unanimously recommends that shareholders vote FOR approval of the compensation of the Company’s executive officers as described in this proxy statement.

CERTAIN TRANSACTIONS

Plexus has a written policy requiring that transactions, if any, between Plexus and its executive officers, directors or employees (or related parties) must be on a basis that is fair and reasonable to the Company and in accordance with Plexus’ Code of Conduct and Business Ethics and other policies. Plexus’ policy focuses on related party transactions in which its insiders or their families have a significant economic interest; while the policy requires disclosure of all transactions, it recognizes that there may be situations where Plexus has ordinary business dealings with other large companies in which insiders may have some role but little if any stake in a particular transaction. Although these transactions are not prohibited, any such transaction must be approved by either a disinterested majority of the board of directors or by the Audit Committee.

Please see “Corporate Governance–Director Independence” for certain transactions and relationships between Plexus and two directors which the board considered when determining the independence of the directors. See also “Corporate Governance–Directors’ Compensation–Compensation of Current and Former Executive Officers who Serve on the Board” regarding agreements with two directors. There were no other transactions in an amount or of a nature that were reportable under applicable SEC rules in fiscal 2012.

REPORT OF THE AUDIT COMMITTEE

The Audit Committee of the board of directors, which was established in accordance with Section 3(a)(58)(A) of the Securities Exchange Act, oversees and monitors the participation of Plexus’ management and independent auditors throughout the financial reporting process and approves the hiring and retention of and fees paid to the independent auditors. The Audit Committee also generally reviews other transactions between the Company and interested parties which may involve a potential conflict of interest. No member of the Audit Committee is employed or has any other material relationship with Plexus. The members are “independent directors” as defined in Rule 5605(a)(2) of the NASD listing standards applicable to the Nasdaq Global Select

50

Market and relevant SEC rules. The Plexus board of directors has adopted a written charter for the Audit Committee, and the current version is available on Plexus’ website.

In connection with its function to oversee and monitor the financial reporting process of Plexus, and in addition to its quarterly review of interim unaudited financial statements, the Audit Committee has done the following:

• reviewed and discussed the audited financial statements for the fiscal year ended September 29, 2012, with Plexus management;

• discussed with PricewaterhouseCoopers LLP, Plexus’ independent auditors, those matters which are required to be discussed by Statement on Auditing Standards No. 61, “Communication with Audit Committees,” as amended (AICPA, Professional Standards, Vol. 1, AU section 380), and SEC Regulation S-X, Rule 2-07 “Communication with Audit Committees”; and

• received the written disclosure and the letter from PricewaterhouseCoopers LLP required by the applicable standards of the Public Company Accounting Oversight Board regarding the independent accountant’s communications with the Audit Committee concerning independence, and has discussed with PricewaterhouseCoopers LLP its independence.

Based on the foregoing, the Audit Committee recommended to the board of directors that the audited financial statements be included in Plexus’ annual report on Form 10-K for the fiscal year ended September 29, 2012. The Audit Committee further confirmed the independence of PricewaterhouseCoopers LLP.

Members of the Audit Committee:	David J. Drury, Chair	Stephen P. Cortinovis
	Peter Kelly	Mary A. Winston

AUDITORS

Subject to ratification by shareholders, the Audit Committee intends to reappoint the firm of PricewaterhouseCoopers LLP as independent auditors to audit the financial statements of Plexus for fiscal 2013. Representatives of PricewaterhouseCoopers LLP are expected to be present at the annual meeting of shareholders to respond to questions and make a statement if they desire to do so.

Fees and Services

Fees (including reimbursements for out-of-pocket expenses) paid to PricewaterhouseCoopers LLP for services in fiscal 2012 and 2011 were as follows:

	2012		2011
Audit fees:	$	1,105,890	$	1,017,965
Audit-related fees:		—		—
Tax fees:		44,575		47,475
All other fees:		—		—

The above amounts relate to services provided in the indicated fiscal years, irrespective of when they were billed. Audit fees related to Plexus’ annual audit and quarterly professional reviews; audit fees also included substantial work related to the certification of Plexus’ internal controls as required by the Sarbanes-Oxley Act. Tax services consisted primarily of tax compliance and other tax advice regarding special Plexus projects. The Audit Committee considered the compatibility of the non-audit services provided by PricewaterhouseCoopers LLP with the maintenance of that firm’s independence.

The Audit Committee generally approves all engagements of the independent auditor in advance, including approval of the related fees. The Audit Committee approves an annual budget (and may from time to time approve amendments thereto), which specifies projects and the approved levels of fees for each. To the extent that items are not covered in the annual budget or fees exceed the budget, management must have such items approved by the Audit Committee or, if necessary between Audit Committee meetings, by the Audit Committee chairman on behalf of the Audit Committee. There were no services in fiscal 2012 or 2011 that were not approved in advance by the Audit Committee under this policy.
