Conflict Minerals Report

For the year ended December 31, 2017

This Conflict Minerals Report of Coherent, Inc. (“we”, “us” or the “Company”) for calendar year 2017 is provided pursuant to Rule 13p-1 (“Rule 13p-1”) under the Securities Exchange Act of 1934 (the “1934 Act”). Please refer to Rule 13p-1, Form SD and the 1934 Act Release No. 34-67716 for definitions to the terms used in this report, unless otherwise defined herein. This report has been prepared by management and includes all majority-owned subsidiaries of the Company.

Introduction

We are one of the world’s leading providers of lasers and laser-based solutions. Our products feature superior reliability and performance, and provide significant cost advantages for commercial and industrial customers competing in the most demanding markets.

Founded in 1966, we design, manufacture and market laser sources, laser tools and systems, accessories and components for customers across the globe. In addition to laser sources and tools, we also offer leading-edge beam forming and beam guidance systems as well as laser beam measurement and control equipment. Our laser products include diode-pumped solid state lasers; fiber lasers; CO2, excimer and ion gas lasers; optically pumped semiconductor lasers; semiconductor lasers; and ultrafast lasers.

The capabilities of our products are exceptionally diverse and are used in a wide range of markets and applications, including microelectronics, including semiconductor test and measurement, and advanced packaging; graphic arts and display; materials processing; instrumentation for biotechnology and medical imaging; production of flat panel displays and solar cells; and in advanced engineering, genetics, biology, chemistry, and physics.

Conflict minerals are currently defined as columbite-tantalite (coltan), cassiterite, gold, wolframite, or their derivatives, which are limited to tantalum, tin, and tungsten, unless the Secretary of State determines that additional derivatives are financing conflict in the Democratic Republic of the Congo (“DRC”) or an adjoining country (together, the “Covered Countries”). Collectively, conflict minerals are known as “3TG” — for tin, tantalum, tungsten, and gold. 3TG are commonly used across the electronics industry generally and are necessary to the functionality and/or production of our products. Uses of the 3TG include:

· Gold is a highly efficient conductor that can carry low voltages and currents and remain free of corrosion. It is used in various Coherent systems as connectors, switch and relay contacts, soldering joints, connecting wires and connection strips.

· Tin is commonly used in the electronics industry for coating lead or zinc and steel to prevent corrosion. Tin can also be found in Coherent systems used in solders for joining electronic circuits.

· Tungsten is often used for electron emitters and is an important mineral for electrical contact materials as tungsten withstands the conditions of an electric arc. Tungsten is an important component in integrated circuitry used within Coherent systems.

· Tantalum is a heat-resistant powder that can hold a high electrical charge; it is an important element in creating capacitors that are used to control current flow in the circuit boards in most Coherent systems.

Reasonable Country of Origin Inquiry (RCOI)

In order to determine the reasonable country of origin of conflict minerals in our products, an internal working group evaluated our supply chain and established a risk-based resource allocation for our RCOI process. This evaluation is regularly updated. Upon review, it was noted that there has been limited year over year change in our supply chain, and therefore the initial process to create four Conflict Minerals assessment categories was again deemed valid for the 2017 reporting cycle. The Supply Chain Conflict Minerals categories are as follows:

Category	Description	Approximate Category Size
One	High Risk. Suppliers from whom we directly source materials that are either fully comprised of, or largely made from, a 3TG material (example, gold)	35 suppliers
Two	Medium Risk. Suppliers from whom we source subsystems, components or other products which are likely to include 3TG (example, electronic subcomponents)	More than 2,000 suppliers representing over 25,000 unique parts
Three	Low Risk. Commonly used and available (catalog) parts that may contain 3TG materials (example, screws, washers, bolts)
Four	Suppliers which provide products which do not include 3TG (example, a plastic button cover)

Following this category review, we conducted a reasonable country of origin inquiry (RCOI) employing a variety of measures to determine whether the necessary conflict minerals in our products originated from the Covered Countries. Category One suppliers were engaged through direct discussions as well as written survey responses. We successfully contacted all Category One suppliers who have reported the following Conflict Minerals status to Coherent: 97% use 3TG and are DRC Conflict Free (flat from the 2016 results and an improvement from 93% as reported in the 2015 Conflict Minerals Report); only one supplier has evidence of 3TG minerals use and reported such 3TG minerals as DRC conflict undeterminable. Coherent will continue to take efforts to identify supply chain risk and determine the source of the 3TG materials; where appropriate, we will pressure our suppliers to find alternate sourcing.

With regards to the large volume of Category Two and Three suppliers, our primary means of determining country of origin is through an active supply-chain survey using the Responsible Business Alliance’s (formerly the Electronic Industry Citizenship Coalition, Incorporated) Responsible Minerals Initiative (RMI) and Global e-Sustainability Initiative (RMI/GeSI), (formerly EICC/GeSI) Conflict Minerals Reporting Template. The RMI/GeSI format has become an industry standard for collecting Conflict Minerals data from the supply chain. To assist us with this survey we retained an expert outside consulting firm. As an on-going project for nearly five years, each Category Two and Three supplier is asked to provide 3TG information, always leveraging the latest RMI/GeSI format. As a formal process, we make minimally three separate attempts to contact Category Two and Three suppliers who have yet to provide a complete RMI form or who have provided an outdated RMI form. At the time of this filing, we

have received responses from Category Two and Three suppliers covering 24,426 unique parts; these parts represent approximately 97% of the parts which are likely to contain 3TG minerals that were used in our end products sold in calendar year 2016. This is up from 93% in 2016, 88% in 2015, 77% in 2014, and 56% in 2013. These parts have the following RMI report status: 41% have been found to be “DRC Conflict Free” (up from 39% in 2016); 39% are “DRC Conflict Undeterminable” (down from 40% in 2016); 13% show 3TG minerals were not used (up from 11% in 2016); 5% of the RMI forms are pending approval of our internal quality check (down from 7% in 2016); and approximately 2% of the parts are covered by suppliers who have yet to respond (equal to 2% in 2016). Due to the incomplete dataset, our conflict minerals classification is currently DRC conflict undeterminable.

For suppliers who have responded to our request for 3TG country of origin, we have been able to determine the following smelter/country information:

Minerals	Smelter / Country of origin may include the following	Change in number of Countries of origin
Gold	Andorra, Australia, Austria, Belgium, Brazil, Canada, China, Czech Republic, Germany, India, Indonesia, Italy, Japan, Kazakhstan, South Korea, Kyrgyzstan, Malaysia, Mexico, Netherlands, Philippines, Poland, Russian Federation, Saudi Arabia, Singapore, South Africa, Spain, Switzerland, Taiwan, Thailand, Turkey, United Arab Emirates, United States, Uzbekistan	14 in 2013 29 in 2014 35 in 2015 36 in 2016 35 in 2017
Tantalum	Brazil, China, Estonia, Germany, India, Japan, Kazakhstan, Macedonia, Mexico, Russian Federation, South Africa, Thailand, United States	7 in 2013 13 in 2014 12 in 2015 14 in 2016 13 in 2017
Tin	Belgium, Bolivia, Brazil, China, Germany, Indonesia, Japan, Malaysia, Peru, Philippines, Poland, Russian Federation, Spain, Taiwan, Thailand, United States, Vietnam	11 in 2013 14 in 2014 17 in 2015 18 in 2016 17 in 2017
Tungsten	Austria, Brazil, China, Germany, Japan, South Korea, Philippines, Russian Federation, United States, Vietnam	6 in 2013 7 in 2014 7 in 2015 10 in 2016 10 in 2017

Due Diligence

We are required to perform due diligence in order to determine the status of the necessary conflict minerals used in our products. Our due diligence processes and efforts have been developed to conform in all material respects with the 2nd edition of The Organization for Economic Co-operation and Development Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas and the related supplements for gold and for tin, tantalum and tungsten (OECD Guidance). The OECD Guidance provides a five-step framework for risk-based due diligence in the mineral supply chain: (1) establish strong company management systems; (2) identify and assess risk in the supply chain; (3) design and implement a strategy to respond to identified risks; (4) carry out independent third-party audit of supply chain due diligence at identified points in the supply chain; and (5) report on supply chain due diligence. We provide further information on each of these elements below.

(1) Establish strong company management systems

In an effort to establish strong management systems, we:

· adopted a corporate policy on conflict-free sourcing including a stated goal to not knowingly source any metals from operations that fund conflict. Further, the policy states that Coherent will seek alternate sources of 3TG if any of our suppliers cannot demonstrate adequate due diligence documenting that the metals used in the manufacture of our products are conflict-free.

· posted our corporate policy on our Internet site, https://cohrcdn.azureedge.net/assets/pdf/ConflictMinerals_Policy_Dec2013.pdf. The content of any website referred to in this Conflict Minerals Report is included for general information only and is not incorporated by reference in this Conflict Minerals Report.

· established a Supplier Environmental Compliance Requirements document outlining the expectation for every supplier to provide Conflict Minerals declaration for all parts and materials provided to Coherent using the RMI/GeSi format. We are currently evaluating the impact of requiring such documentation to be completed prior to the retention of any new supplier on a worldwide basis.

· actively monitor, collect, analyze and aggregate conflict minerals RMI/GeSI templates and supporting documentation from manufacturers into reports that are easily downloaded for our compliance efforts from a third party part search and BOM manager tools. Our third party Conflict Minerals Module, identifies the most up to date DRC conflict mineral statuses, links to all supporting documents and policies including RMI-GeSI templates and certificates of compliance, and retain all supplier history regarding compliance. Detailed searches associate suppliers with specific smelter companies, locations, substances, miner locations, and RMI-GeSI CFS lists.

· identified over 2,000 suppliers representing over 26,000 unique parts as a part of our Conflict Minerals management program.

· sent surveys to all suppliers and made multiple attempts to contact those suppliers who have yet to respond. Each returned survey is audited internally for its completeness and any potential inconsistencies. Progress is regularly reported to senior leadership and shared with the Corporate Supply Chain organization.

(2) Identify and assess risk in the supply chain

In an effort to identify and assess risk in the supply chain, we have:

· required all in-scope suppliers to disclose active smelters and refiners through the submittal of a complete RMI/GeSi form. Smelters are reviewed to determine whether they are active in the Conflict-Free Smelter Program (“CFSP”). Pursuant to our corporate policy, future decisions on sourcing will be impacted by a supplier’s response and their participation in the CFSP program.

· engaged directly with each Category One supplier to confirm that each such supplier is providing us with a completed RMI form and, where appropriate, will consider other suppliers if the supplier is unable to declare their products as DRC Conflict Free.

(3) Design and implement a strategy to respond to identified risks

In an effort to design and implement a strategy to respond to identified risks, we:

· regularly report to senior management on the status of our Conflict Minerals Program. Additionally, conflict minerals status updates are included in our ISO140000 review management meetings.

· regularly review our contingency planning for our supply chain, including replacement risk for those suppliers who have not yet replied to our information requests.

(4) Carry out independent third-party audit of supply chain due diligence at identified points in the supply chain

· We do not have a direct supplier relationship with smelters. We will continue to support the development and implementation of independent third party audits of smelters such as the Conflict-Free Smelter Program and will encourage our suppliers to purchase materials from audited, conflict-free smelters. We are continuing to evaluate direct independent third party audits of our Category One suppliers and an assessment of their diligence steps taken with regards to any purchases made from smelters.

(5) Report on supply chain due diligence

In an effort to report on supply chain due diligence, we have:

· leveraged our new Corporate Policy on Conflict Minerals and Environmental Requirements document, which is provided to all current suppliers (as well as future potential suppliers). Further, suppliers are encouraged to sign a “Certificate of Compliance with Coherent’s Environmental Policy,” which includes the obligation to provide Conflict Minerals declarations.
