Document

This Retirement and Transition Agreement (“Agreement”) is made by and between Patrick J. Jermain (“You”) and Plexus Corp. (“Plexus”), and sets forth the conditional compensation and benefits that Plexus will provide as you transition from your role as Executive Vice President and Chief Financial Officer of Plexus to your retirement. Your active employment will cease effective at midnight on July 31, 2026 (“Retirement Date”).

During the time you were employed as Executive Vice President and Chief Financial Officer, you had access to and were involved in the review, development, and use of Confidential Information and Trade Secrets of Plexus and its affiliated companies (collectively “Plexus”) and their customers and suppliers, which Plexus has a legitimate business interest and need to protect against unauthorized use and disclosure.

You are under contractual, statutory, and common law duties and obligations to treat and hold Confidential Information and Trade Secrets as confidential and not use or disclose the same for any purpose competitive with or otherwise contrary to the legitimate interests of Plexus and/or its customers or suppliers. Your obligations with respect to the confidentiality and safeguarding of this information extend for a period of time post-employment, which you acknowledge to be reasonable and appropriate.

Plexus also has a strong business interest in ensuring the orderly and smooth transition of your role as Executive Vice President and Chief Financial Officer to your successor and in reaching an amicable separation with you without the time, cost, and distraction of legal claims and/or disputes.

By entering into this Agreement, you and Plexus desire to fully and finally resolve all claims and potential claims that exist now or that may exist between us in the future and to provide for a smooth and orderly transition from your role as Executive Vice President and Chief Financial Officer.

1. Ending Date of Your Role as Executive Vice President and Chief Financial Officer and Resignation from Other Officer Positions. You will continue in your role as Executive Vice President and Chief Financial Officer of Plexus until midnight on May 10, 2026. Effective on the same date and time, you will assume the transitional role outlined in Section 2 below and you will resign from all officer, director, committee, and other roles you hold with Plexus.

2. Transition Assistance. From May 11, 2026 to and including midnight on your Retirement Date, you will provide such transitional services as are necessary or as may reasonably be assigned to you by Plexus’ Chief Executive Officer to ensure the continuity of operations and the seamless transition of duties and responsibilities to your successor (“Transition Period”). During the Transition Period, you will continue to be paid the same base pay as you were receiving on May 10, 2026, and you will continue to be eligible for those employee benefits as are available to Plexus’ regular full-time exempt salaried employees.

3. Final Pay and Ending Date of Employee Benefits. You will be paid final pay earned in the last payroll period of the Transition Period by direct deposit on the next regular corporate payroll date occurring for salaried exempt employees after your Retirement Date. Your final pay will be subject to and reduced by applicable income and payroll tax withholdings and other deductions required by law. You will receive your final pay regardless of whether you sign this Agreement. Your eligibility for Plexus employee benefits shall end on your Retirement Date. Information concerning continuation of medical, dental, vision, and flexible spending benefits will be sent directly to your home from United Healthcare, the COBRA Administrator. This will be sent after your Retirement Date. Regardless of whether you sign this Agreement, you will be eligible for COBRA continuation at your sole cost, subject to your timely election and timely payment of premiums. If you sign this Agreement, Plexus will provide you with COBRA premium assistance as set forth in Section 5.1 below.

5. Conditional Compensation and Benefits. In consideration of your timely execution and return of this Agreement in accordance with Section 9 below, and conditioned on your full compliance with the terms and conditions of this Agreement, including, specifically, the restrictive covenants set forth in Section 14, Plexus will provide you with the conditional compensation and benefits set forth below. If you do not timely sign and return this Agreement, you will not receive the conditional pay and benefits offered below (except to the extent such items are provided under the terms of your existing arrangements).

5.1 COBRA Premium Assistance. As additional consideration for acceptance of this Agreement, Plexus will subsidize your COBRA medical insurance premium payment in the same amount as Plexus was contributing to the cost of your medical insurance prior to your Retirement Date for up to eighteen (18) months, provided that you timely elect COBRA and remain eligible for it during that time. Once you have timely elected COBRA coverage, and have signed and not revoked this Agreement, United Healthcare will bill you an amount equal to the active employee contribution for the coverage elected. In other words, you will pay the same amount for medical, dental, and vision COBRA coverage as you paid for these coverages as an active employee for the period defined above.

(a) Outstanding Unvested Restricted Stock Units. If you timely sign and do not revoke your acceptance of this Agreement, your outstanding restricted stock units (as shown below) (“RSUs”) will remain outstanding and will vest according to their terms on the vesting dates noted in the table below. You will have no risk of forfeiture of the RSUs provided that you comply with all terms and provisions of this Agreement, including, but not limited to, the restrictive covenant provisions of Section 14, and/or you do not otherwise engage in conduct detrimental to the interests of Plexus. For clarity and avoidance of doubt, the restrictive covenant provisions of Section 14 of this Agreement shall continue in full force and effect until the later of the 15th of February 2029 or the date of the Certification of the Compensation and Leadership Development Committee with regard to the TSR PSU with an estimated vest date of 15th of February 2029, as shown in the Table on the next page:

Upon vesting, the shares of stock related to your RSUs will be delivered to your E*TRADE account net of taxes on the original vesting dates (subject to any six-month delay required for compliance with Section 409A of the Internal Revenue Code of 1986 (“Section 409A”). The shares are not subject to any further restrictions or requirements after vesting, except for potential clawback under applicable law or in the event of a material breach by you of this Agreement.

(b) Outstanding Unvested Performance Stock Units. If you timely sign and do not revoke your acceptance of this Agreement, your outstanding unvested Performance Stock Units (“PSUs”) (as shown in the Table on the next page) will remain outstanding and will be allowed to vest, to the extent earned, on the date of the Certification of the Compensation and Leadership Development Committee. The number of PSUs you will ultimately earn will be based on the final performance results for the performance period and noted in your individual grant agreement. There will be no risk of forfeiture of these PSUs provided that you comply with all terms and provisions of this Agreement, including, but not limited to, the restrictive covenant provisions of Section 14, and/or you do not otherwise engage in conduct detrimental to the interests of Plexus. For clarity and avoidance of doubt, the restrictive covenant provisions of Section 14 of this Agreement shall continue in full force and effect until the later of the 15th of February 2029 or the date of the Certification of the Compensation and Leadership Development Committee with regard to the TSR PSU with an estimated vest date of 15th of February 2029, as shown in the Table on the next page:

Any and all awards other than those set forth above shall be forfeited and will not be paid out to you in cash or equity.

5.3 Prorated Variable Incentive Compensation Plan Bonus. Notwithstanding your Retirement Date before the end of the plan year, you will be eligible to be paid a prorated Variable Incentive Compensation Plan payment as part of the conditional benefits offered under this Agreement. Such payment will be calculated based on achievement of personal goals for similarly situated executive level participants and of corporate goals relating to Revenue and ROIC targets for the plan year. The prorated bonus will be paid by direct deposit and is subject to applicable income and payroll tax withholdings and other deductions required by law and shall be paid in November 2026 when VICP bonuses are paid to other VICP-eligible employees per the plan schedule.

5.4 Transfer of Company Vehicle. On your Retirement Date or as soon thereafter as is practicable, Plexus will gift and transfer to you the company-leased vehicle assigned to you. Plexus will pay the lease payoff amount of approximately $54,675.72. You will have sole liability and responsibility to pay the income tax, cost of titling, and licensing and registration fees incurred in connection with the transfer. After the transfer, you will be solely responsible and liable for maintenance, repair, insurance premium costs, and servicing of the vehicle.

14.2 Non-Competition. During the Restrictive Covenant Period (defined above), you agree that you will not, either directly or indirectly, within the United States, Canada, Mexico, Germany, Scotland, Romania, China, Thailand or Malaysia, do any of the following: (a) provide services to a competitor of the Company in a position in which your duties would be substantially similar to the duties that you performed for Plexus in the two (2) years preceding your Retirement Date, and would require you to work on, supervise or support products or services competitive to any of the products or services you worked on, supervised, or supported or about which you gained Confidential Information in the two (2) years prior to your Retirement Date; or (b) provide services to a competitor of the Company in a position in which Confidential Information or Trade Secrets of the Company to which you had substantial exposure in the two (2) years prior to your Retirement Date, would reasonably be considered useful.

14.3 Non-Interference with Customers. During the Restrictive Covenant Period (defined above), you agree that you will not, either directly or indirectly, service, solicit, or entice, or in any manner attempt to cause any customer to purchase products or services sold by the Company from any source other than the Company, nor in any manner cause or attempt to cause any customer or supplier of the Company to diminish their business relationship with or divert their business from the Company. For purposes of this section, a “customer” of the Company shall mean any person or entity (a) with whom you directly or indirectly dealt on behalf of the Company within the two-year period immediately preceding your Retirement Date or (b) about whom/which, during the two (2) years prior to your Retirement Date, you acquired or had substantial exposure to non-public information that could reasonably be used to the competitive disadvantage of the Company absent your full compliance with this Agreement.

14.4 Non-Interference with Employees. During the Restrictive Covenant Period (defined above), you shall not directly or indirectly encourage, advise or solicit (or assist another person or entity in encouraging, advising or soliciting) any Company employee who, within the two (2) years prior to your Retirement Date, you directly supervised or had material contact with, or about whom you acquired non-public information as a result of your employment with Plexus, where such information could be used to facilitate the recruitment of such employee or otherwise induce such employee to leave or diminish their employment with the Company.

14.5 Confidential Information and Trade Secrets. You agree that during the Restrictive Covenant Period (defined above), you shall keep confidential and not use or disclose any Confidential Information related to Plexus’ customers, personnel, designs, pricing, marketing plans, budgets, strategies, financial or other proprietary information that is not otherwise known or readily available to the general public (“Confidential Information”). You understand that your obligations under this Agreement are in addition to and not in lieu of any protections under the Uniform Trade Secrets Act or similar laws. With regard to information constituting a trade secret under applicable law, you shall keep confidential and not use or disclose any such trade secret for as long as such information remains a trade secret under the Uniform Trade Secrets Act and Wis. Stat. Section §134.90. Without limiting

the generality of the foregoing, you specifically reaffirm your obligations under the Employee’s Agreement with Regard to Proprietary Information Including Inventions, Patents, Copyrights, Trade Secrets, and Confidential Information you signed with Plexus (“the Proprietary Information Agreement”).

15. Defend Trade Secrets Act Disclosure. The foregoing notwithstanding, you may not be held criminally or civilly liable under any federal or state trade secret law for the disclosure of a trade secret that is made: (a) in confidence to a federal, state, or local government official, either directly or indirectly, or to an attorney, and provided that such disclosure is solely for

the purpose of reporting or investigating a suspected violation of the law, or (b) in a complaint or other document filed in a lawsuit or other proceeding, provided that such filing is made under seal. Additionally, in the event you file a lawsuit against Plexus for retaliation by it against you for reporting a suspected violation of law, you have the right to provide trade secret information to your attorney and use the trade secret information in the court proceeding, although you must file any document containing the trade secret under seal and you may not disclose the trade secret, except pursuant to court order.

16. Agreement to Cooperate with Litigation. You agree that if Plexus or its legal counsel reasonably deems it necessary, you will cooperate as a witness for any litigation to which Plexus is a party where you have relevant information or evidence to the case, and you agree to make yourself reasonably available to provide truthful testimony and cooperation to Plexus with regard to the pending litigation and/or in connection with Plexus’ investigation into claims and defenses for such litigation.

17. Remedies. In the event that you fail to comply with any of the terms of this Agreement or its post-employment obligations, Plexus may, in addition to any other remedies it may have, reclaim any amounts paid and/or the value of any equity provided to you under this Agreement or terminate any benefits or payments that are later due under the provisions of this Agreement, including forfeiture of any RSUs or PSUs, without waiving the Release provided in this Agreement.

18. Severability. If any provision of this Agreement is found by a court of competent jurisdiction to be invalid, illegal, or unenforceable in any respect, or enforceable only if modified, such finding shall not affect the validity or enforceability of any other portion of this Agreement, which shall remain in full force and effect and continue to be binding on the Parties. Each and every provision of this Agreement is declared to be separate, independent, divisible, and severable from one another such that if one provision is declared unenforceable the other separate, independent, and divisible provisions will continue as valid and in effect.

19. Attorneys’ Fees and Costs. If you breach any of the terms of this Agreement or the post-termination obligations referenced in it, to the extent authorized by Wisconsin law, you will be responsible for payment of all reasonable attorneys' fees and costs that Plexus incurs in the course of enforcing the terms of this Agreement, including demonstrating the existence of a breach and any other enforcement efforts.

20. Final and Complete Agreement. This Agreement represents the entire agreement and understanding between Plexus and you concerning the subject matter hereof and supersedes and replaces any and all prior agreements concerning your relationship with Plexus or its affiliates, oral or written, except for the Employee’s Agreement With Regard to Proprietary Information executed by you, which shall remain in full force and effect. No provision of this Agreement may be waived or amended except by an agreement signed by an authorized representative of Plexus.

and construed in accordance with the law of the State of Wisconsin, irrespective of any conflicts of law provisions of any state, and the Parties hereby consent to the exclusive jurisdiction of the U.S. District Court-Eastern District of Wisconsin located in Green Bay, Wisconsin, or, if federal subject matter does not exist, to exclusive jurisdiction of the Wisconsin Circuit Court in Winnebago County.
