CONFLICT MINERALS REPORT OF

PLEXUS CORP.

IN ACCORDANCE WITH RULE 13p-1

UNDER THE SECURITIES EXCHANGE ACT OF 1934

FOR THE REPORTING PERIOD FROM

JANUARY 1 TO DECEMBER 31, 2015

Introduction

This Conflict Minerals Report (the “Report”) of Plexus Corp. (“Plexus,” the “Company,” “we,” “us,” or “our”) has been prepared for calendar year 2015 under the Securities Exchange Act of 1934 (the “Act”). The term “conflict mineral” is defined as (A) columbite-tantalite (coltan), cassiterite, gold, wolframite or their derivatives, which are limited to tantalum, tin and tungsten; or (B) any other mineral or its derivatives determined by the Secretary of State to be financing conflict in the Democratic Republic of the Congo (the “DRC”) or an adjoining country (collectively, the “Covered Countries”). Numerous terms in this Report are defined in Rule 13p-1 of the Act and Form SD (collectively, the “Conflict Minerals Rule”) and the reader is referred to those sources, and also to Securities and Exchange Commission (“SEC”) Release No. 34-67716 (August 22, 2012) under the Act for such definitions.

In accordance with the Conflict Minerals Rule, we undertook efforts to determine whether the conflict minerals necessary to the functionality or production of products that we manufacture, or contract to manufacture, were sourced from the Covered Countries, or are from recycled or scrap sources. The Company designed its due diligence efforts to conform, in all material respects, with the framework presented by the Organisation for Economic Co-operation and Development (the “OECD”)in the publication Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas and related supplements for each of the conflict minerals (collectively, the “OECD Guidance”).

The statements below are based on the due diligence activities performed to date and on the information available at the time of this filing. Factors that could affect the accuracy of these statements include, but are not limited to, incomplete supplier data or a lack of available smelter data, errors or omissions by suppliers or smelters, evolving confirmation of smelters, incomplete information from industry or other third-party sources, and other issues.

fulfillment (to end customers) and global logistics management and Aftermarket Services. To service the complexities that the Company's customers' products demand, Plexus utilizes its Product Realization Value Stream, addressing its customers' products from concept to end of life.

Description of Products

Plexus does not sell “Plexus-branded” products. Plexus provides services for original equipment manufacturers (“OEMs”) with a focus on supporting mid-to-low volume, higher complexity customer programs characterized by unique flexibility, technology, quality and regulatory requirements. The products falling within the scope of this Report include the assemblies and products that we manufactured or contracted to manufacture for customers in the market sectors listed above during calendar year 2015. Although Plexus did not find any evidence that the required conflict minerals contained in these assemblies or products directly or indirectly benefited armed groups in the Covered Countries, we were unable to conclude that any of these assemblies and products were definitively “DRC conflict free.”

Conflict Minerals Policy

Plexus is committed to ensuring ethical sourcing and has made significant progress in developing supply chain transparency. We have a Conflict Minerals Policy Statement (the “Conflict Minerals Policy”), which is posted on our website at the following link:

http://www.plexus.com/sites/default/files/resources/plexus_conflict_minerals_policy_statement.pdf.

Reasonable Country of Origin Inquiry (“RCOI”)

Plexus conducted a good faith RCOI regarding the conflict minerals in the materials, components and finished goods supplied to the Company. We utilized a third-party service provider (the “Provider”)to assist in supplier outreach and our due diligence procedures.

Plexus reviewed the assemblies and products that it manufactured or contracted to manufacture for customers during calendar year 2015 and identified suppliers that supply components or products, or engage in manufacturing activities, that are likely to contain conflict minerals. We removed from the list of suppliers all service providers, indirect materials suppliers, and inactive suppliers that did not supply goods to Plexus. We focused our RCOI efforts on suppliers comprising approximately the top 90% of the Company’s spend with suppliers.

The Provider conducted the supplier survey portion of the RCOI. Suppliers received a communication describing the compliance requirements and requesting information on the conflict minerals in their products and the smelters or refiners of those conflict minerals. The Provider, on behalf of the Company, utilized version 4.01 of the Conflict-Free Sourcing Initiative’s (the “CFSI”) Conflict Minerals Reporting Template (“CMRT”). The Provider, on behalf of Plexus, engaged approximately 2,000 suppliers determined to be in scope for purposes of our RCOI efforts to collect information regarding the presence and sourcing of conflict minerals in the products supplied to the Company.

The Provider followed up with all unresponsive suppliers through a defined process. The Provider utilized both automated and direct email communications. The communications offered assistance and further information to suppliers about the requirements of the Conflict Minerals Rule and the Company’s compliance program. A minimum of two attempts were made to contact unresponsive suppliers. Additionally, suppliers were contacted to address incomplete data, missing smelters or refiners, and invalid submissions. The Provider monitored and tracked all invalid or incomplete supplier submissions.

2

Although we requested information at a product level, a majority of suppliers provided CMRT responses at a company or division level that included information on all products sold by the supplier to its customers, even though Plexus may have purchased only a limited subset of components or products from the supplier. Therefore, the information provided by these suppliers was not necessarily limited to smelters or refiners that were potentially part of the Company’s supply chain.

On the basis of the responses during our RCOI, the Company was unable to determine that the conflict minerals necessary to the functionality or production of our products did not originate in the Covered Countries. As a result and in accordance with the Conflict Minerals Rule, Plexus undertook the due diligence measures described below on the source and chain of custody of the conflict minerals in its supply chain.

Design of Due Diligence

As previously disclosed, the Company’s due diligence measures were designed to be in conformity, in all material respects, with the internationally recognized due diligence framework as set forth in the OECD Guidance.

The design of the Company’s due diligence measures took into account the OECD’s recommendations for “downstream” actors with no direct relationships with smelters or refiners. “Downstream” refers to the supply chain from smelters or refiners to retailers and manufacturers, whereas “upstream” refers to the supply chain from the mines to the smelters or refiners.

Plexus does not have a direct relationship with any smelters or refiners and therefore, does not perform direct audits of the due diligence practices of these entities. The Company instead relies on internationally-recognized validation schemes that facilitate independent third-party audits of smelters or refiners and validate that smelters or refiners have met the requirements of the OECD Guidance, such as the CFSI Conflict-Free Smelter Program. Plexus supports this program through membership and participation in the CFSI as a member of the Electronics Industry Citizenship Coalition (“EICC”).

Due Diligence Measures Performed

Plexus’ overall conflict minerals program is based on the five-step framework of the OECD Guidance. Plexus followed the five-step framework established by the OECD Guidance while performing our due diligence measures for calendar year 2015, which consisted of the following steps:

Step 1:Maintain strong company management systems

Step 2:Identify and assess risks in the supply chain

Step 3:Design and implement a strategy to respond to identified risks

Step 4:Carry out independent third-party audit of smelters’ and refiners’ due diligence

practices when required

Step 5:Report annually on supply chain due diligence

Step 1: Maintain strong company management systems

Plexus has established an internal management system designed to assist with complying with the Conflict Minerals Rule. As previously discussed, we also retained the services of the Provider to assist with our efforts. Through use of the Provider’s web-based reporting tool we are able to collect and store supplier data and CMRTs, communicate with suppliers and monitor risks in our supply chain. The use of this tool and our other management systems has provided an opportunity for the Company to assist our suppliers in understanding our expectations and requirements and to increase the rate of responses received from our suppliers.

3

Control Systems:

The Company’s Conflict Minerals Policy outlines the expectation that all Plexus suppliers abide by the requirements of the Plexus Supplier Code of Conduct, which prohibits human rights abuses and unethical practices. The Conflict Minerals Policy also requires all suppliers to comply with applicable legal standards and requirements and provide us with completed conflict minerals declarations annually.

We periodically review our Conflict Minerals Policy and will make updates as necessary and appropriate. If a supplier fails to comply with our Conflict Minerals Policy, we may reconsider our willingness to continue to partner with that supplier.

Supplier Engagement:

In an effort to strengthen engagement with suppliers, Plexus utilized version 4.01 of the CMRT and the Provider’s web-based reporting tool for collecting CMRTs from our supplier base. The use of these tools and our other engagement efforts, have allowed us to assist our suppliers in understanding our expectations.

Company Level Grievance Mechanism:

As an additional means of communication regarding conflict minerals, Plexus employees and other stakeholders can communicate directly and confidentially with the Company’s Corporate Compliance Officer and executive management by using the Plexus Ethics Hotline, as outlined in the Plexus Code of Conduct and Business Ethics, which is available at www.plexus.com (follow the links to “Investor Relations” and then to “Corporate Governance”).

Document Retention:

Plexus is retaining documentation regarding its conflict minerals program for calendar year 2015 in accordance with its record retention guidelines.

Step 2: Identify and assess risks in the supply chain

Plexus performed multiple steps in an effort to ensure that risks were identified and assessed during the execution of its conflict minerals program. This included risks associated with smelters or refiners, supplier responses, and with suppliers’ internal policies and programs.

The Provider verified whether the metals processors identified by each supplier on its CMRT are actually smelters, refiners, or recyclers of conflict minerals (“verified smelters or refiners”) by comparing the facilities reported by suppliers to the CFSI's Standard Smelter List, the data gathered by the U.S. Department of Commerce, and by conducting its own independent research. The Provider also researched and reviewed mine information for all verified smelters or refiners in an effort to determine the country of origin of the minerals processed.

The Provider attempted to match each identified smelter or refiner to available lists of smelters and refiners that have been certified by internationally-recognized validation schemes, such as the CFSI Conflict-Free Smelter Program, the London Bullion Market Association Good Delivery program (“LBMA”), and the Responsible Jewellery Council Chain-of-Custody Certification program (“RJC”). If a smelter or refiner was not certified by an internationally-recognized scheme, the Provider attempted to contact the entity to gather more information about its sourcing practices. In addition, the Provider also performed research using publicly available sources of information regarding the smelter’s or refiner’s sourcing practices.

4

The Company sought to understand the risk levels associated with conflict minerals in the supply chain. A smelter’s or refiner’s overall risk is based on various factors, including whether the smelter has been identified as “valid” and has an associated Smelter Identification Number (under the CFSI, this is known as a CID), as well as the smelter’s geographic location, including its proximity to the Covered Countries.

The Provider assessed supplier risk based on its determination of the likelihood that a supplier provided conflict minerals to the Company that may have originated from sources that are not conflict free, considering the smelters or refiners declared by that supplier on its CMRT.

Additionally, we evaluated suppliers based on the strength of their conflict minerals programs. The criteria used to evaluate the strength of a supplier’s program consisted of the following:

• Does the supplier have a policy in place that includes DRC conflict-free sourcing?

• Has the supplier implemented due diligence measures for conflict-free sourcing?

• Does the supplier verify due diligence information received from suppliers?

• Does the supplier’s verification process include corrective action management?

The Company has, through the Provider, provided training to suppliers on conflict minerals, the Conflict Minerals Rule and the CMRT. This includes instructions on completing the CMRT and discussions with supplier personnel.

Tracing materials back to their mine of origin is a complex aspect of responsible sourcing in the supply chain. Plexus has determined that seeking information about conflict minerals smelters and refiners in the supply chain represents the most reasonable effort we can make to determine the mines or locations of origin of the conflict minerals in the supply chain. This was done by adopting the methodology outlined by the OECD Guidance and by requiring suppliers to conform with the same standards to meet the OECD Guidance, and report to Plexus using the CMRT. Through this process, we believe we have made reasonable efforts to determine the mines or locations of origin of the conflict minerals in our supply chain.

Step 3: Design and implement a strategy to respond to identified risks

Following the assessment of supplier risk discussed above, Plexus followed up with suppliers whom we had reason to believe may be sourcing conflict minerals originating from a smelter or refiner in the Covered Countries. We also followed up with any supplier that did not submit a valid response to the CMRT and encouraged them to provide complete and accurate data via the CMRT.

As stated in our Conflict Minerals Policy, Plexus requires all in-scope suppliers to provide completed conflict minerals declarations using the CMRT. Plexus may reconsider its willingness to partner with suppliers that fail to comply with our Conflict Minerals Policy.

Step 4: Carry out independent third-party audit of smelter/refiner due diligence practices

Plexus relies on multi-stakeholder initiatives that provide verification processes for smelters or refiners who provide conflict minerals to companies in its supply chain. Plexus, as a purchaser of component parts, is many steps removed from the mining of conflict minerals. We do not purchase raw ore or unrefined conflict minerals and we do not conduct purchasing activities directly in the Covered Countries. In addition, we do not perform or direct audits of the smelters or refiners listed by our suppliers as being potentially a part of our supply chain.

Step 5: Report annually on supply chain due diligence

This Report (and the related Form SD) was filed with the SEC and is available on the Plexus website at: http://www.plexus.com/sites/default/files/resources/2015_plexus_conflict_minerals_report.pdf.

Due Diligence Results

Using the processes outlined above, Plexus surveyed the in-scope suppliers for calendar year 2015 and reviewed the responses received. As previously noted, the Company, along with the Provider, followed up with suppliers who did not respond or who provided incomplete responses, or whose responses contained inconsistencies, in an effort to secure valid and complete responses.

On the basis of the due diligence measures discussed in this Report, Plexus does not have sufficient information from our suppliers or otherwise to conclusively determine the country of origin of the conflict minerals in the products we manufactured, or were contracted to manufacture, in calendar year 2015 or whether the conflict minerals were from recycled or scrap sources. As a result of these due diligence measures, Plexus has identified the 320 smelters and refiners listed in Annex A to this Report as potentially processing the conflict minerals provided by its suppliers. Based on information provided by Plexus’ suppliers, CFSI’s country of origin data and the research provided by the Provider, the smelters or refiners listed in Annex A are believed to have provided conflict minerals to Plexus’ supply chain.

As previously disclosed, Plexus does not do business directly with any of the smelters or refiners listed. The list was generated based on information received from the Company’s suppliers. Plexus continues to conduct independent research on smelters and refiners and will work with suppliers throughout our supply chain to help improve and refine reported information in future years. Plexus will continue to communicate expectations and information requirements to our direct suppliers. We will continue to make inquiries to direct suppliers and undertake additional risk assessments when potentially relevant changes in facts or circumstances are identified.

Although we requested information at a product level, as previously disclosed, a majority of suppliers returned information at a company or division level, not at a product level. Therefore, the information provided was not necessarily limited to smelters or refiners confirmed to be in the Company’s supply chain. In addition, various supplier responses were incomplete, as all minerals supply chain participants continue to map their upstream supply chains. As a result, Plexus is unable to definitively validate whether the facilities listed in Annex A.

Steps to Continuously Improve Due Diligence

In addition to the initiatives outlined above, Plexus plans to take the following steps during the next compliance period to improve the due diligence conducted and to further mitigate the risk that these conflict minerals benefit armed groups:

• Actively participate in and support industry trade groups to help improve communication throughout the supply chain. Plexus is an applicant member of the EICC, and will continue its membership activity through the coming year.

• Continue to partner with certain customers to help educate suppliers on our ongoing expectations supporting responsible sourcing decisions.

6

• Continue to expand and improve supplier engagement. With the goal of increasing the response rate and quality of survey responses, Plexus will continue to reach out to suppliers, support education and training, and seek to integrate expectations into new supplier contracts.

• Evaluate ongoing supplier relationships with those suppliers that do not comply with our Conflict Minerals Policy.

• Continue to enhance and refine due diligence measures. Based on an evaluation of the 2015 supplier survey process, Plexus will continue to work with third-party service providers to enhance its supplier survey and due diligence processes.
