PLEXUS CORP

BOARD OF DIRECTORS MEETINGS

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

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

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

BOARD LEADERSHIP STRUCTURE

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

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

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

THE DUTIES OF THE BOARD’S LEAD DIRECTOR

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