PLANTRONICS, INC.

CONFLICT MINERALS REPORT

FOR THE YEAR ENDED DECEMBER 31, 2015

Introduction

This Conflict Minerals Report for the calendar year ended December 31, 2015 (“CY 2015”) is presented by Plantronics, Inc. (“we” or the “Company”) to comply with Rule 13p-1 under the Securities Exchange Act of 1934 (the “Exchange Act”).

Plantronics is a global company that manufactures and contracts to manufacture communications headsets and related equipment, as listed on our Form SD of which this report is a part, from a global supply chain with many levels. We work with our supplier base to identify the facilities processing Tin, Tantalum, Tungsten and Gold (3TG) in our supply chain.

As part of the RCOI described in Form SD, Plantronics performed a supplier survey using the Conflict Free Sourcing Initiative (CFSI) Conflict Minerals Reporting Template (CMRT) during the second half of CY 2015. All 78 direct suppliers providing components used in Plantronics products within scope of the rule as described further in the Form SD) were included in the survey utilized for both RCOI and Due Diligence. The information obtained in the survey indicated that there was reason to believe that a portion of the 3TG used in Plantronics products may have originated in the Democratic Republic of Congo or the adjoining countries (the “covered countries”) and were not exclusively from scrap or recycled sources, triggering the due diligence steps described in the following sections.

Design and Execution of Due Diligence

We designed and implemented the majority of our due diligence measures prior to the current reporting year CY 2015. These measures were continued in CY 2015 and are described herein. They are designed to conform, in all material respects, to the framework in The Organization for Economic Co-operation and Development (OECD) Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas (OECD 2012) including the Supplement on Tin, Tantalum and Tungsten, as well as those portions of the OECD Supplement on Gold applicable to downstream companies (collectively the “OECD Guidance”). In accordance with the five step OECD Guidance, our measures are designed to determine, to the best of our ability, the source and chain of custody of the 3TG materials necessary for the functionality and/or production of our products, to ascertain if the materials originated in one of the covered countries, and if so, whether armed groups directly or indirectly benefited as a result.

1.Establish Strong Company Management Systems

• Plantronics has a company Conflict Minerals team consisting of representatives from the Engineering Compliance, Legal, Operations/Materials, Quality and Supplier Quality Engineering departments.

• Plantronics has a conflict minerals policy statement publicly available at http://www.plantronics.com/us/company/global-citizenship/#section5.

• We maintain a grievance reporting system open to both employees and suppliers through our ethics reporting system at http://www.plantronics.com/us/company/global-citizenship/#section5.

• In addition to any annual survey using the CMRT, supplier obligations and requirements in this regard have been incorporated into the Supplier Code of Conduct, which is available on the corporate governance section of our website. In addition, Conflict Minerals Requirements, including due diligence and participation in annual supplier survey, are included in our controlled “Purchasing & Supplier Management” methods and procedures document.

• Plantronics purchase orders and contracts include a supplier Conflict Minerals Due Diligence expectations clause.

• Plantronics establishes and maintains long term relationships with the majority of our first tier Original Design, Contract, and Custom Part Manufacturers to facilitate engagement with suppliers to improve due diligence performance.

• Since we have limited direct relationships with any facilities processing 3TG, we are an active participant in the Conflict Free Sourcing Initiative (CFSI) (http://www.conflictfreesourcing.org/about/members-and-collaborations/) to aid the development of conflict free supply chains at the smelter or refiner level and further upstream.

• Conflict Minerals materials records are maintained pursuant to our records retention policy.

• The Conflict Minerals Team issues a formal report of progress and findings to upper management quarterly.

• We created a controlled Methods and Procedures document regarding Conflict Minerals Due Diligence Procedures.

• For CY2014 we purchased and installed a software tool to improve management and auditability of supplier communications, as well as to receive, evaluate, store, and determine statistics on incoming CMRTs which we continued to use in CY 2015.

• Starting in CY 2015 our supplier quality team conducted audits of selected first tier suppliers’ conflict minerals due diligence programs. These audits assessed policy, training, record retention and data validation. Eight such audits were performed in 2015, three audits resulted in supplier corrective action plans, all of which were successfully completed.

2.Identified and Assessed Risk in the Supply Chain

• We conducted a supplier survey of the 78 direct first tier suppliers providing products or components within scope of the rule; necessary for the functionality of our products and likely to contain 3TG. Prior to conducting the survey we conducted one-on-one training with selected critical suppliers in Asia, either in person or by web. The survey required that the supplier return the then current version of the CMRT (4.0x). Our request included information to inform the suppliers of Plantronics’ Conflict Minerals Rule reporting obligations as well as the assistance required from our supply chain, and the resulting expectations for the sourcing of conflict minerals. A link to the Plantronics’ Conflict Minerals policy was included in the request.

• Reminders, late notices and finally delinquent notices were sent to non-responsive suppliers. Commodity Managers were involved in escalation at the time of the delinquent notices. We did not find it necessary to restrict business or disengage from any supplier due to failure to respond to the survey.

• All incoming CMRTs underwent a two-step review process. The first step is a PASS/FAIL check by our Conflict Minerals software for completeness and internal consistency of the declaration and submitted smelter list. A message was automatically sent by the system to suppliers submitting CMRTs containing errors with an explanation of the error and a request for corrective action and re-submission.

• Once CMRTs passed this first evaluation, they were then evaluated by internal compliance engineers on an ACCEPT/MODIFY basis for consistency with the known content and complexity of the products or components provided. A message was sent to suppliers submitting CMRTs found insufficient or incomplete with an explanation and request for corrective action. We continued to communicate with those suppliers to improve the content and quality of their responses. 100% of the suppliers responded by returning a CMRT, and eventually 97% of the responses were accepted.

• In addition, we used a data mining service to obtain conflict minerals information, also using the CFSI CMRT, from manufacturers of off-the-shelf components with whom we had no direct relationship.

• Facilities processing 3TG reported by the supply chain were categorized, based on information available through CFSI, as

◦ Legitimate Smelters or Refiners (“SORs”),

◦ Entities known to Not be legitimate SORs.

• In addition to SORs known to, or believed to, source from the covered countries who were not validated as conflict free, Plantronics identified non-smelters as a source of risk, since the actual source of the 3TG is not known.

3.Designed and Implemented a Strategy to Respond to Identified Risks

• We have continuously conducted research into “alleged” SORs- companies reported that were not on any list of known SORs- reported in our supplier survey to determine the nature of these entities’ business. This effort is done both through collaborative efforts in CFSI, and our own independent research in areas where we have associates that speak the local language. Through these efforts the final number of “alleged” SORs has been significantly reduced progressively from the number in previous reporting years, from 83 in CY2013 to 46 in CY2014 to none in the final CY 2015 survey results. This is attributable to determining that many of the alleged SORs were indeed legitimate SORs or legitimate SOR aliases, or determination of the company’s actual business, as well as improved supplier reporting.

• We also asked suppliers initially reporting non-smelters or alleged smelters to verify the information and if possible, identify actual smelters. We gave feedback concerning the actual nature of a non-smelter’s business to the supplier when such information was available, primarily through CFSI collaborative efforts.

• We continued to work within CFSI teams to determine the legitimacy of any “alleged SORs” reported by our supply chain. We encouraged known smelters not yet validated as Conflict Free to participate in Conflict Free Smelter Program (CFSP).

4.Carry out independent 3rd Party Audit of Smelters’/Refiners’ Due Diligence Practices

• Because Plantronics has few direct business relationships with smelters, we worked within industry initiatives to implement validation of DRC conflict free smelters as outlined in OECD Guidance for downstream companies. We relied on the results of audits conducted by CFSP to determine smelters’ Due Diligence Practices. As an active contributing member of the CFSI, we actively participated in outreach to confirmed smelters to encourage participation in CFSP.

• A Plantronics associate acted as a single point of contact to directly help two smelters prepare for the CFSP audit.

5.Report Annually on Supply Chain Due Diligence

• Our Form SD and this Report together constitute our annual report on our Conflict Minerals Due Diligence. These have been filed with the SEC and are available on our website at http://www.plantronics.com/us/company/global-citizenship/#section5.

Results of due diligence performed

• Most of our direct supplier responses represented their supply chain at a company-level rather than being product-specific. Therefore, the list of processing facilities contained in this report may contain more facilities than those that actually process the conflict minerals contained in our products. The total number of unique entities reported as smelters or refiners by the Plantronics supplier base as result of CY 2015 Supplier Survey was 299. Of these, 279 have been confirmed as being legitimate SORs by the CFSI, 20 are known to not be legitimate SORs, and there were no reported entities whose status could not be confirmed as of our cutoff date of April 15, 2016.

• Of the 279 legitimate SORs reported by the supplier base, 210 had been validated by CFSP as being in conformance with a CFSP recognized conflict free audit protocol (CFSP, London Bullion Market Association, or Responsible Jewelry Council). Another 46 were in process or communication with CFSP, or participating in another recognized program, but had not achieved validated status as of April 30, 2016.

• The twenty entities reported by our supply chain that are not legitimate smelters fell into three categories: companies that are group companies with a number of legitimate smelter locations (9), formerly legitimate smelters that had either temporarily or permanently suspended operations (4) or companies downstream of the actual smelter (7).

• The remaining legitimate smelters require outreach to encourage participation in a conflict free program. Plantronics actively participates in CFSI targeted outreach through email and, in countries where we have associates that speak the local language, telephone calls. We have also begun to interact directly with selected smelters to help guide them through the CFSP audit process.

• Of the 279 legitimate SORs reported by the supplier base, we determined during RCOI that there was no reason to believe that 136 of the SORs sourced or may have sourced any minerals from the covered countries.

• Of the remaining smelters with definitive RCOI information available through CFSI or other publicly available information, 19 were known or reasonably believed to source minerals from the DRC, the surrounding countries or countries known as possible routes for smuggling or export of minerals out of the DRC. All 19 are CFSP validated. The facilities not eliminated during RCOI, along with the location of the facility and the conflict free status are listed in Table I. The countries believed to be the source of 3TG in our products are listed in Table II.

• While we did not find any information that would give us reason to believe armed groups directly or indirectly benefitted as a result of the mining, transport for processing of 3TG in our products, the smelter information collected from our suppler base included non-smelters as well as a number of legitimate smelters or refiners that had not been audited and validated as DRC Conflict Free by the CFSP, or any other recognized organization. For these reasons, we are unable to determine that any of our products or product categories are DRC Conflict Free.

Steps to be taken to further mitigate risk

We intend to continue taking the following steps to build on momentum established in the past two years to improve the due diligence conducted, and to further mitigate the risk that the necessary conflict minerals in our products benefit armed groups in the Covered Countries:

• Improve the accuracy of our smelter list by requesting that the suppliers providing Parent companies of SORs determine which smelter site is involved, verify that materials from smelters that have ceased operations are still in their supply chain, and try to obtain smelter information from downstream companies named on their CMRT.

• Try to increase the number of off-the-shelf part manufacturers from whom conflict minerals data is obtained.

• Maintain membership and active participation within CFSI, conducting research into smelter operations, sourcing and compliance. Continue to conduct coordinated outreach to encourage more smelters to participate in recognized conflict free validation programs such as the Conflict Free Smelter Program.

• Continue to engage directly with selected smelters to help guide them through the CFSP audit process.

• Encourage our supply chain to use validated conflict free smelters, in particular those sourcing responsibly within the DRC and adjoining countries, to the greatest extent possible.

Table I. Plantronics Smelter List

List and status of SORs are as of April 30, 2016 and status data is from CFSI. The list includes 143 recognized SORs that are either known to obtain at least some minerals from the covered countries or are SORs where the source of the minerals was not disclosed and could not be determined. It does not include those SORs that source only from outside the covered countries as determined through RCOI, or process only recycled or scrap materials. “Country” refers to the location of the facility, not the source of minerals. The smelter location was not used for RCOI, since it does not necessarily determine the source of the ore, although location near abundant mineral resources can be an indicator of mineral sourcing. The general geographical breakdown of all the reported smelters is as follows:

Region	Number
Asia	175
Europe	36
North America	31
South America	16
Russia and Central Asia	15
Middle East	4
Africa	2

Status is defined as:

Compliant: Smelters or refiners that have been audited and have been validated as compliant with the Conflict-Free Smelter Program or cross recognized (LBMA, RJC) assessment protocols.

Not Validated: Legitimate Smelters or refiners who have not yet completed a CFSP or cross recognized audit validating a conflict free process.

CFSP Active: Smelters and refiners on the Active list have committed to undergo a CFSP audit.
