Section 1 - Conflict Minerals Disclosure

Items 1.01 and 1.02 Conflict Minerals Disclosure and Report, Exhibit

Reasonable Country of Origin Inquiry:

Brief description of inquiry:

An analysis of our products was performed on the basis of which we concluded that they each contain one or more of the conflict minerals (defined below), which are necessary to their functionality or production. Therefore, the products that we manufacture or contract to manufacture are subject to the reporting obligations of Rule 13p-1 under the Securities Exchange Act of 1934. To satisfy the reasonable country of origin inquiry ("RCOI") requirement of the Conflict Minerals Rule adopted by the SEC under Section 1502 of the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Act”), Super Micro Computer, Inc. ("Supermicro" or "we") has, in good faith, surveyed its suppliers using the Conflict-Free Sourcing Initiative ("CFSI") Conflict Minerals Reporting Template. The scope of the survey was to determine whether any of the conflict minerals (defined in Section 1502(e)(4) of the Act to include columbite-tantatlite, cassiterite, wolframite and gold and their derivatives, which are limited to tin, tantalum, tungsten and gold) that are not from recycled or scrap sources originated in the Covered Countries, which include the Democratic Republic of the Congo (the “DRC”) or an adjoining country as defined in Section 1502(e)(1) of the Act. As part of the RCOI process, we performed a scoping exercise to understand our supply chain including the relevant supplier and sub-supplier population and the products or components procured from such suppliers. We adopted a framework for evaluating responses from suppliers and identifying potential red flags in suppliers’ responses. We have also adopted a company level policy on conflict minerals which has been published on our website at http://www.supermicro.com/about/policies/Supermicro_Conflict_Minerals_Statement.pdf.

Based on the approach described above, we believe that we have conducted a good faith reasonable country of origin inquiry for the calendar year ended December 31, 2015. We have documented the performance of the RCOI and our analysis of the supplier responses and the scoping of our products and suppliers for our internal record keeping purposes.

Results of inquiry:

As of the date of this filing, based on the RCOI responses and an analysis of such responses, as it applies to the calendar year ended December 31, 2015, we cannot ascertain the source mine and country of origin of all of the relevant conflict minerals which are necessary to the functionality or production of our products. Therefore, we proceeded with additional due diligence measures for the purpose of determining the source and chain of custody of such conflict minerals.

Exercise Due Diligence on the Source and Chain of Custody of Our Conflict Minerals:

We are required to exercise due diligence on the conflict minerals' source and chain of custody and to follow a nationally or internationally recognized due diligence framework. Our due diligence measures have been designed to conform, in all material respects, with the framework in the Organisation for Economic Cooperation and Development Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict Affected and High Risk Areas (the "OECD Guidance"). We have adopted and communicated our conflict mineral policy to our suppliers and customers and implemented RCOI procedures to collect additional information from our new and existing suppliers. In addition, we have established programs to encourage our suppliers to source their conflict minerals from certified conflict-free smelters.

Conflict Minerals Report

For the Calendar Year Ended December 31, 2015

I. Introduction

This report for the year ended December 31, 2015 has been prepared pursuant to Rule 13p-1 and the Specialized Disclosure Report on Form SD ("Form SD") under the Securities Exchange Act of 1934 (collectively, the "Rule"). The Rule was adopted by the Securities and Exchange Commission (the "SEC") to implement reporting and disclosure requirements related to conflict minerals as directed by the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (the "Dodd-Frank Act"). The Rule imposes certain reporting obligations on SEC registrants whose manufactured products contain conflict minerals which are necessary to the functionality or production of their products. Conflict minerals are defined as cassiterite, columbite-tantalite, gold, wolframite, and their derivatives, which are limited to tin, tantalum, tungsten, and gold ("3TG").

If a registrant determines that conflict minerals are necessary to the functionality or production of products manufactured or contracted by the registrant to be manufactured, the registrant must submit a Form SD which describes the reasonable country of origin inquiry (“RCOI”) that it undertook to determine whether such necessary conflict minerals originated from the Democratic Republic of the Congo (the “DRC”) or an adjoining country (collectively, the “Covered Countries”).

If, on the basis of its RCOI, a registrant knows or has reason to believe that any of the necessary conflict minerals in its supply chain may have originated in any of the Covered Countries, or if it is unable to determine the country of origin of those conflict minerals, the issuer must exercise due diligence on the conflict minerals’ source and chain of custody and submit a Conflict Minerals Report to the SEC that includes a description of those due diligence measures.

This report has been prepared by Super Micro Computer, Inc. (herein referred to as “Super Micro” the “Company,” “we,” “us,” or “our”). The information contained in this report includes the activities of all of the Company's majority-owned subsidiaries and variable interest entities that are required to be consolidated.

II. Company Overview

We are a global leader in high-performance, high-efficiency server technology and innovation. We develop and provide end-to-end green computing solutions to the cloud computing, data center, enterprise IT, big data, HPC and embedded markets. Our solutions range from complete server, storage, blade and workstations to full racks, networking devices, server management software and technology support and services.

We conduct our operations principally from our headquarters in California and facilities of our subsidiaries in Taiwan, the Netherlands, China and Japan. We sell our server systems and subsystems and accessories through our direct sales force as well as through distributors and Original Equipment Manufacturers ("OEMs").

III. Supply Chain Overview

Our supply chain operations for our server products include sourcing, order management, manufacturing, delivery, and return. We procure server components from the following four major types of suppliers:

• Manufacturers or direct suppliers;

• Contract manufacturers producing items to match specifications and standards set by us;

• Distributors or resellers of manufactured components for other manufacturers; and

• Customers providing us certain parts and materials to be used to fulfill their orders.

Logistics and service providers were excluded from the reasonable country of origin inquiry ("RCOI") and due diligence measures discussed below because we have concluded that they do not provide us with any products within the scope of the Rule.

As explained further below, we rely upon our suppliers to provide information on the origin, source and chain of custody of the conflict minerals contained in product components and materials. We commenced conflict minerals due diligence in 2013.

Based on representations from these suppliers, we have determined that they obtain conflict minerals used in our products from the following types of processing facilities:

1

• Tin, Tungsten, Tantalum - From smelters which procure the relevant ore and then pass it through smelting and/ or refining, as applicable.

• Gold - From smelters/ refiners which either obtain gold from the mines or through recycling.

IV. Conflict Minerals Policy

We are committed to complying with Section 1502 of the Dodd-Frank Act and achieving the goal of confirming that the materials used in our products are procured from conflict-free sources. We have considered the Rule’s requirements and related guidance from the Organisation for Economic Cooperation and Development (the “OECD”), and we expect our suppliers to comply with the Code of Conduct of the Electronics Industry Citizenship Coalition (the “EICC”) and conduct their business in accordance with our supply chain responsibility expectations, as documented in our Conflict Mineral Policy (the "CM Policy") at http://www.supermicro.com/about/policies/Supermicro_Conflict_Minerals_Statement.pdf.

In support of this policy, we will:

• Exercise due diligence with suppliers of products containing or suspected to contain conflict minerals consistent with the OECD's Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas, 3rd Edition and the related supplements on gold, tin, tantalum and tungsten, (the “OECD Guidance”) as tailored to include steps appropriate for downstream companies and encourage our suppliers to do likewise with their suppliers;

• Provide, and expect our suppliers to cooperate in providing, due diligence information to confirm that the tantalum, tin, tungsten and gold in our supply chain are procured from conflict free sources; and

• Collaborate with our suppliers and others on industry-wide solutions through our membership in the Conflict-Free Sourcing Initiative ("CFSI") and participation in industry-wide conflict minerals forums to encourage the manufacture of products that are DRC conflict free.

V. Reasonable Country of Origin Inquiry

Our supply chain due diligence "scope of work" included our existing component suppliers that provide products and components that contain one or more 3TG minerals (collectively referred to as "In Scope Suppliers"). To help establish our supply chain sourcing programs, we have adopted the CFSI’s Conflict Mineral Reporting Template ("CMRT") and launched a due diligence survey using the CMRT for In Scope Suppliers, which suppliers represent 100% of our total 2015 product-related sourcing expenditures. We reviewed our In Scope Suppliers and categorized them into three tiers based on procurement value. We identified our top 22 suppliers by procurement value as the first tier, followed by the next top 47 suppliers as the second tier and the remaining 262 suppliers as the third tier. The suppliers in the first and second tiers accounted 98% of our total 2015 product-related sourcing expenditures. The purpose for this classification was to facilitate a focused follow-up process with our suppliers in securing responses to the CMRT on a timely basis through appropriate allocation of resources. The percentage of CMRT received from our In Scope Suppliers during 2015 has increased to 76% in 2015 compared to 27% in 2014. The data on which we relied to determine the country of origin of the minerals was obtained through our membership in the CFSI, using the Reasonable Country of Origin Inquiry report for us.

After conducting our RCOI, we were unable to determine the country of origin of the conflict minerals contained in our products that are not from recycled or scrap sources. Given this result, we determined that the Rule requires us to exercise due diligence on the source and chain of custody of the conflict minerals contained in our products, using a framework that conforms to a nationally or internationally recognized due diligence framework.

VI. Due Diligence

a. Due Diligence Framework

We have exercised due diligence on the source and chain of custody of the necessary conflict minerals used in our products to identify minerals originating from the Covered Countries that are not from scrap or recycled sources. The due diligence processes and efforts have been developed based on the five-step framework proposed by the OECD Guidance and the related supplements for gold, tin, tantalum and tungsten.

Our conflict minerals due diligence process includes:

•Establishment of strong company management systems;

•Identify and assess risks in the supply chain;

2

•Design and implement a strategy to respond to identified risks;

•Carry out independent third-party audit of smelter/refiner’s due diligence practices; and

•Report annually on supply chain due diligence.

b. Inherent Limitations on Due Diligence Measures

As a downstream purchaser of conflict minerals, we do not have direct relationship with smelters or refiners that produce the conflict minerals within our supply chain. Accordingly, our due diligence measures can provide only reasonable, not absolute, assurance regarding the source and chain of custody of the necessary conflict minerals. Our due diligence processes are based on the necessity of seeking data from our direct suppliers and those suppliers seeking similar information within their supply chains to identify the original sources of the necessary conflict minerals. We also rely, to a large extent, on information collected and provided by independent third party audit programs. Such sources of information, as well as our smelters, may yield inaccurate or incomplete information.

c. Brief Description of Due Diligence Measures Taken

(i) Establishment of Strong Company Management Systems:

We have established a management system for complying with applicable conflict minerals reporting and disclosure rules. Our management system includes the development of a Conflict Minerals Oversight Committee led by our Senior VP of Operations, Senior VP and Chief Financial Officer and General Counsel, and a team of subject matter experts from relevant functions such as purchasing, quality compliance, finance, and legal. The team of subject matter experts is responsible for implementing our conflict mineral compliance policy and strategy. The Oversight Committee is briefed periodically about the results of our due diligence efforts and reports periodically to the Audit Committee of our Board of Directors.

We maintained our CM Policy that states our position on the use of conflict minerals. Our CM Policy has been communicated to all existing suppliers and was provided to new suppliers as part of our supplier "onboarding" process. We have provided training to our conflict mineral related team members.

(ii) Identification and Assessment of Risks in the Supply Chain:

We have made reasonable efforts to identify all In Scope Suppliers that supply products that may potentially contain conflict minerals by conducting a supply chain survey using the CFSI CMRT; requesting our In Scope Suppliers to identify smelters and refiners and countries of origin of the conflict minerals in products they supply to us; following up with In Scope Suppliers that do not respond to the CMRT by requesting their responses; comparing smelters and refiners identified by our supply chain survey against the list of facilities that have received a “conflict-free” designation from the CFS Program, which designations provide country of origin; and maintaining documentation of reasonable efforts we have made to identify and assess supply chain risks. We have also reviewed the responses to identify potential red flags for further follow-up.

(iii) Strategic Response to Identified Risks:

We have implemented a risk mitigation response to monitor and track suppliers, smelters and refiners identified as not meeting the requirements set forth in our Conflict Minerals Sourcing Policy or contractual requirements to determine their progress in meeting those requirements. We will continuously make reasonable efforts to encourage suppliers who are sourcing from non-conflict-free smelters to move towards the use of conflict-free smelters. If a supplier fails to remedy the risks identified by our compliance risk assessment, we will escalate the matter to the Conflict Minerals Oversight Committee to determine whether to approve or reject the supplier based on the following factors: a cost and benefit analysis; evaluation of potential risk factors; any existing competitive bids; and whether the supplier is a single source supplier to the Company. If the Oversight Committee decides to continue a business relationship with a non-compliant supplier due to inherent limitations of our supply chain, we will use reasonable efforts to follow up with the supplier for its correction plan, and encourage the supplier to work with smelters that are certified through CFSI's CFS program. We also provide periodic compliance updates or reports to our Conflict Minerals Oversight Committee summarizing our risk mitigation efforts.

3

(iv) Independent 3rd Party Audit of Smelter/Refiner’s Due Diligence Practices:

We do not have a direct relationship with 3TG smelters and refiners, nor do we perform direct audits of these entities that provide our supply chain the 3TG. However, we do rely upon industry efforts, including CFSI, to influence smelters and refiners to get audited and certified through CFSI’s CFS program. Pursuant to the Rule, this report is not subject to an independent private sector audit.

VII. Efforts to Determine the Mine or Location of Origin of the Conflict Minerals in Our Products and Facilities Used to Process the Conflict Minerals

The results of our RCOI and due diligence on the source and chain of custody of our necessary conflict minerals are the product of our iterative and escalating data collection and dialogue process with our In Scope Suppliers. This process is designed to obtain information regarding the smelters and refineries from which suppliers source such 3TG minerals and to confirm the status of such smelters or refineries as verified by the CFSI as a method of assessing the mine and location of origin of such conflict minerals.

Based on the responses that we received from our suppliers, we identified 358 smelters and refineries as potential sources of 3TG minerals that were reported to be in our supply chain, of which 213 have been verified by the CFSI to be conflict free and 34 are in the process of being verified. Table 1 below presents, by mineral, the total number of smelters and refineries identified and the percentage verified to be conflict free or in the CFSI Verification Process. See Appendix I for a list of smelters and refiners by name verified as conflict-free.

Table 1 - Smelters and Refiners Verified as Conflict-Free or in the CFSI Verification Process by Mineral.

	Total Smelters and Refiners by Mineral	Number Verified or In Process	Percentage Verified or In Process
Gold	138	94	68	%
Tantalum	55	46	84	%
Tin	108	77	71	%
Tungsten	57	30	53	%

As to the remainder of the smelters and refineries that are not verified by the CFSI, we were unable to determine the mines of origin or the minerals sourced from such smelters and refineries.

VIII. Due Diligence Process Improvement Efforts

Due to the level of complexity of our products and the respective supply chains and our position in these supply chains as a downstream company, it will take additional time and resources for a number of our suppliers to verify the source mines and country of origin of all of the minerals used by their smelters. We intend to take the following steps to continue to improve our due diligence measures and to further mitigate the risk that trade in the conflict minerals contained in our products could benefit armed groups in Covered Countries:

• Continuing to focus our efforts on collaborating with industry peers through our membership in the CFSI to improve the systems of transparency and control in our supply chain, including through our use of the latest revision of the CMRT in connection with our diligence of our supply chain.

• Continuing to partner with our In-Scope Suppliers and others on industry-wide solutions through our membership in CFSI in an effort to collaboratively increase the number of verified smelters.

• Enhancing our engagement with our relevant first-tier suppliers in order to further build their knowledge and capacity so they are able to provide more complete and accurate information on the source and chain of custody of conflict minerals in our supply chain.

• Encouraging our supply chain to source conflict minerals from certified Conflict Free Smelters or source 3TG minerals from smelters located outside the DRC and participate in third-party audits that use the CFSI Conflict-Free Smelter Program assessment protocols.

• Continuing our work to refine the process for conducting follow-up with our surveyed suppliers to more effectively resolve unreasonable or illogical responses in their surveys.
