**Section 1 - Conflict Minerals Disclosure**

**Items 1.01 Conflict Minerals Disclosure and Report**

**<u>Reasonable Country of Origin Inquiry:</u>** 

**Brief description of inquiry:**

An analysis of products of Super Micro Computer, Inc. ("we," or "our") was performed, on the basis of which we concluded that certain products contain one or more of the "conflict minerals" (defined in Section 1502(e)(4) of the Dodd-Frank Wall Street Reform and Consumer Protection Act (the "Act") to currently include columbite-tantalite, cassiterite, wolframite and gold and their derivatives, and also known as 3TG), 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, as amended. To satisfy the reasonable country of origin inquiry ("RCOI") requirement of the Conflict Minerals Rule adopted by the Securities and Exchange Commission (the "SEC") under the Act, we have, in good faith, surveyed our suppliers using the Responsible Minerals Initiative ("RMI") Conflict Minerals Reporting Template and used RCOI information provided by the RMI. These methods help determine whether any of the subject minerals 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.

We have documented the outcome 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, and as in prior reporting years, we cannot ascertain the source mine and country of origin of all of the above defined minerals which are included in the functionality or production of our products. Additionally, a substantial number of our suppliers either report sourcing from the DRC or an adjoining country, or report use of a smelter located in one or more of these countries. Therefore, we proceeded to exercise due diligence on the source and chain of custody of conflict minerals, as described in the Conflict Minerals Report included as Exhibit 1.01 to this Form SD.

**<u>Due Diligence on the Source and Chain of Custody of Our Conflict Minerals:</u>**

Our due diligence measures have been designed to conform, in all material respects, with the framework in the Organization for Economic Cooperation and Development Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict Affected and High-Risk Areas. We have communicated our conflict mineral policy to our suppliers and customers and implemented due diligence procedures to collect additional information from new and existing suppliers. We have a policy statement covering conflict minerals to best communicate expectations to suppliers.

## Exhibit 1.01

**Exhibit 1.01**

**Super Micro Computer, Inc.**

**Conflict Minerals Report**

**For the Calendar Year Ended December 31, 2025**

**I. Introduction**

This report for the year ended December 31, 2025 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, as amended (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 3TG 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 3TG originated from the Democratic Republic of the Congo 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 3TG in its supply chain may have originated in any of the Covered Countries and knows they are not, or has reason to believe that they may not be, from recycled or scrap sources, the issuer must exercise due diligence on the 3TG 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 "Supermicro," the "Company," "we," "us," or "our"). The information contained in this report includes the activities of all of the Company's majority-owned subsidiaries. This Report has not been subject to an independent private sector audit.

**II. Company Overview**

We are a global leader in Application-Optimized Total IT Solutions. Founded and operating in San Jose, California, we are committed to delivering first-to-market innovation for Enterprise, Cloud, AI, and 5G /Edge IT Infrastructure. We are a Total IT Solutions provider offering servers, AI systems, storage, IoT devices, switch systems, software, and support services. Our expertise in motherboard, power, and chassis design further enhances our development and production capabilities, enabling next-generation innovation from cloud to edge for our global customers. Our products are designed and manufactured in-house in the U.S., Taiwan, and the Netherlands, leveraging global operations for scale and efficiency, and they are optimized to improve total cost of ownership and reduce environmental impact through green computing initiatives. Our award-winning portfolio of Server Building Block Solutions® allows customers to optimize for their specific workloads and applications by selecting from a broad family of systems built on our flexible and reusable building blocks that support a comprehensive set of form factors, processors, memory, GPUs, storage, networking, power, and cooling solutions, including air cooling, free-air cooling, and liquid cooling.

Our sales and marketing activities operate through a combination of our direct sales force and indirect sales channel partners. We work with distributors, value-added resellers, system integrators, and original equipment manufacturers ("OEMs") to market and sell our optimized solutions to their end customers in our indirect sales channels.

**III. Supply Chain Overview**

Our supply chain operations for our hardware products include sourcing, order management, manufacturing, delivery and return. For those products, we procure components from the following five major types of suppliers:

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Manufacturers or direct suppliers;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Contract manufacturers producing items to match specifications and standards set by us that, in some cases, source independently (but within the bounds of Supermicro specifications);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Distributors or resellers of manufactured components for other manufacturers;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Manufacturers of finished goods that are requested by some customers. These items and their suppliers are not included in our conflict minerals exercise as they are off-the-shelf products that are not "manufactured or contracted to be manufactured" by Supermicro so are outside the scope of the RCOI and due diligence measures under the Rule; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Customers providing us certain parts and materials to be used to fulfill their orders. These items and their suppliers are not included in our conflict minerals exercise as they are the responsibility of the respective customers and do not always reflect our supply chain. Furthermore, they are not "manufactured or contracted to be manufactured" for Supermicro so are outside the scope of the Rule.

Logistics, packaging, consumables (e.g. CDs and DVDs) and service providers were excluded from the 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 and third parties to provide information on the origin, source and chain of custody of the 3TG contained in product components and materials. We do not source directly from mines or smelters any of the 3TG found in our products. We commenced 3TG due diligence in 2013.

Based on representations from our in-scope suppliers, we have determined that 3TG minerals sourcing is most frequently from smelters that procure ore from mines, and in some instances from smelters that use recycled or scrap materials. Based on our due diligence, nearly 20% of our in-scope suppliers source 3TG from smelters that use up to 100% scrap or recycling; however, none indicate they source 3TG exclusively from scrap or recycling. We do not know the portion of any given smelter's output represented by scrap or recycled material.

**IV. Conflict Minerals Program**

We are committed to complying with Section 1502 of the Dodd-Frank Act and to furthering our goal of ensuring that the materials used in our products are procured from conflict-free sources. We have considered the Rule's requirements and related due diligence recommendations from the Organization for Economic Cooperation and Development (the "OECD"), and we expect our suppliers to comply with the Code of Conduct of the Responsible Business Alliance ("RBA") and conduct their business in accordance with our supply chain responsibility expectations, as documented in our Responsible Mineral Sourcing Statement at <u>https://www.supermicro.com/about/policies/Supermicro_Responsible_Mineral_Sourcing_Statement.pdf</u> 

In support of this program, we will continue to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a.review and potentially update our Responsible Mineral Sourcing Statement as a device for communicating current expectations to suppliers and partners. Continue to review the terms and conditions of our vendor/supplier documents and policies to emphasize further our goal of achieving a conflict-free supply chain;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b.exercise due diligence with suppliers for products containing or suspected to contain 3TG (collectively referred to as "in-scope" suppliers), consistent with the OECD's Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas ("CAHRA"), 3rd Edition and the related supplements on gold, tin, tantalum and tungsten (the "OECD Guidance"), and encourage our suppliers to do likewise with their suppliers;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;c.utilize common tools that allow effective organization and reporting on use of minerals, such as the Conflict Minerals Reporting Template ("CMRT") and Extended Mineral Reporting Template ("EMRT") developed by the Responsible

------

Minerals Initiative ("RMI"), including to help identify potential sourcing from CAHRAs and other supplier response red flags;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;d.collaborate with our suppliers and multi-stakeholder groups, including maintaining membership in the RMI, to participate in new solutions for responsible minerals sourcing, and conduct coordinated outreach to address upstream compliance concerns, including concerns involving sourcing from CAHRAs or other high-risk areas;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;e.provide education and training to our staff and suppliers on the laws and industry standards for responsible sourcing of minerals, and continue to adjust the scope of suppliers and minerals that we focus on for due diligence based on relevant minerals; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;f.promptly inform suppliers of any smelters or refiners that are reported as not conformant according to the Responsible Minerals Assurance Process ("RMAP") process, or actively seeking RMAP assessment, and request alternative sourcing until those smelters or refiners become conformant.

The results of our RCOI and due diligence on the source and chain of custody of 3TG that are necessary for our products are the result of an iterative and advancing data collection process with our in-scope suppliers. This process is designed to obtain information regarding the smelters and refiners from which suppliers source 3TG minerals, and to confirm the status of smelters or refiners as assessed by the RMAP, to determine the origin of the minerals.

For the 2025 reporting year, we asked all suppliers that were in-scope for 3TGs to indicate whether cobalt or mica is present in parts provided to us, and if so, to complete the EMRT. This request resulted in the completion of 232 supplier EMRTs by 182 suppliers. We remain committed to the responsible sourcing of all minerals, particularly where mining and supply chain practices may present risks of conflict and/or human rights abuse.

**V. Reasonable Country of Origin Inquiry and Results**

We have adopted the CMRT to conduct a RCOI survey for in-scope suppliers. Through the refinement of our in-scope suppliers over the last thirteen years, we believe that, to the best of our knowledge, all of our suppliers sourcing 3TG in the 2025 reporting year have been requested to respond to the survey. The data on which we relied to determine the country of origin of the minerals was obtained almost entirely through the survey of our suppliers, our use of RCOI information provided by the RMI and interaction with other RMI members.

Responses from our in-scope direct suppliers included 100 declaring 3TG mineral sourcing from Covered Countries and no suppliers indicating 3TG sourcing from Covered Countries is unknown. Compared to the 2024 reporting year, this reflects a slight decrease in the number of suppliers declaring sourcing from Covered Countries and a decrease in those indicating "unknown" — from 6 to 0. All suppliers who responded to the RCOI survey disclosed whether their conflict minerals originated from Covered Countries. In addition, continuing challenges in chain of custody verification surrounding 3TG, notably with gold, create mineral source uncertainty. Therefore, after conducting our RCOI, we determined it is likely that the country of origin for some of the 3TG contained in our products are Covered Countries. Given this result, we determined that the Rule requires us to exercise due diligence on the source and chain of custody of the 3TG contained in our products, using a framework that conforms to a nationally or internationally recognized due diligence framework.

**VI. Due Diligence Inquiry and Results**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**a.Due Diligence Framework**

We have exercised due diligence on the source and chain of custody of the necessary 3TG used in our products to identify minerals originating from the Covered Countries that are not from scrap or recycled sources. The design of our due diligence processes has been developed to conform to the five-step framework proposed by the OECD Guidance and the related supplements for 3TG. Our due diligence process utilizes internal tracing and review efforts, the efforts of in-scope suppliers that we collect sourcing information, and the efforts of the RMI, Responsible Jewelry Council ("RJC") and the London Bullion Market Association ("LBMA").

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**b.Limitations on Due Diligence Measures**

------

Our due diligence measures can provide only reasonable, not absolute, assurance regarding the source and chain of custody of the necessary 3TG. Our due diligence processes are based on the necessity of seeking data from our in-scope direct suppliers and those suppliers seeking similar information within their supply chains to identify the original sources of the necessary 3TG. 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**c.Conformance with OECD Due Diligence Guidance**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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 a Conflict Minerals Oversight Committee led by our acting Chief Compliance Officer, and a team of subject matter leads across key departments responsible for implementing our Conflict Minerals Program. The Conflict Minerals Oversight Committee is briefed periodically about the results of our due diligence efforts and reports to the Audit Committee of our Board of Directors.

We maintain our Responsible Mineral Sourcing Statement (former Conflict Minerals Policy) that states our position on the use of conflict minerals. Our Statement 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 related team members. Additionally, our policy is prominently posted on our public facing website.

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

To address the risk of sourcing minerals linked to supporting conflict or human rights abuses, we have made reasonable efforts to identify and assess all in-scope suppliers. This includes conducting a supply chain survey using the CMRT, requesting our in-scope suppliers to identify smelters and refiners and countries of origin of the 3TG in products they supply to us, comparing smelters and refiners identified by our supply chain survey against the RMI's list of conformant facilities under the RMAP assessment protocols, examining where smelters source from via the RMI's RCOI data and requiring in-scope suppliers to update or explain incomplete, inaccurate or outdated information on CMRTs. Furthermore, we ask all suppliers to avoid using non-compliant or non-active smelters until they can obtain a compliant or actively seeking compliance status. We look at the various categories of smelters beyond RMAP "compliant" to assess whether incremental progress is being made, or whether smelters appear to be avoiding audits. Our Responsible Mineral Sourcing Statement helps reduce the likelihood of onboarding new suppliers who do not comply with the RMAP assessment protocols and thus are not in alignment with our goal of sourcing from conflict-free suppliers.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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 Responsible Minerals Sourcing Statement or contractual requirements to determine their progress in meeting our policy. We will continuously make reasonable efforts to encourage suppliers who are sourcing from non-compliant smelters to transition to compliant smelters. If a supplier fails to remedy the risks identified, 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) Independent 3rd Party Audit of Smelter/Refiner's Due Diligence Practices:

We do not independently perform direct audits of smelters or refiners. As an alternative, we consider information collected and provided by independent third-party audit programs, such as RMAP, the LBMA and the RJC. Additionally, we perform indirect outreach and participate in industry efforts, including through the RMI, to help encourage smelters and refiners to voluntarily participate in the RMAP validation process.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(v) Report Annually on Supply Chain Due Diligence

A Form SD and a Conflict Minerals Report as an exhibit thereto are filed annually with the SEC. The Form SD and Conflict Minerals Report are also available on our website at <u>https://ir.supermicro.com/financials/sec-filings/default.aspx</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**d. Due Diligence Results**

We collected 247 final CMRT forms from 195 suppliers that we believe are in-scope for 3TG (several provided multiple CMRTs covering different products from different internal organizations). Our efforts to collect missing CMRTs, as well as those provided as "interim" or "incomplete" CMRTs (i.e., those with a less than 90% completion rate) will continue. We once again reviewed our direct-material suppliers this reporting year by cross-referencing accounting/orders, approved vendors and bills of material to identify suppliers that could be in-scope. Based on the responses that we received from our suppliers, we identified the following smelters and refiners in our supply chain for the 2025 reporting year:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 258 known smelters and refiners as potential sources of 3TG minerals

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 222 (86.0%) have been verified by the RMI to be conformant with the RMAP assessment protocols

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 6 (2.3%) are active (i.e., they are in the process of being audited or have committed to the audit process)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 30 (11.6%) are validated smelters or refiners but are not conformant or active according to RMAP

Table 1 below presents, by mineral, the total number of smelters and refiners identified that are RMAP-conformant or actively seeking conformance for the 2025 reporting year. The percentage of conformant or in-process smelters is similar for 2024 and 2025 reporting years. We continue to emphasize to suppliers the need to communicate upstream about the problematic smelters and exploring alternative sources.

**Table 1** - Smelters and Refiners Verified as RMAP-Conformant or actively seeking conformance by Mineral for the 2025 reporting year.

| | | | |
|:---|:---|:---|:---|
| | **Total Smelters and Refiners by Mineral** | **Total Number (%) of Conformant Smelter and Refiners** | **Total Number (%) of Active Smelter and Refiners** |
| **Gold** | 102 | 93 (91.2%) | 3 (2.9%) |
| **Tantalum** | 40 | 38 (95.0%) | 1 (2.5%) |
| **Tin** | 79 | 55 (69.6%) | 2 (2.5%) |
| **Tungsten** | 37 | 36 (97.3%) | 0 |

---

See Appendix I for a list, by name, of validated smelters and refiners found within our supply chain in the 2025 reporting year.

Supermicro's stated policy is that all suppliers must take all reasonable steps to directly or indirectly source 3TG from RMAP conformant (including cross-recognized) smelters. This remains an unachieved goal, where at least 30 smelters reported during the 2025 reporting year are not RMAP conformant or active.

![image_0a.jpg](image_0a.jpg)

**VII. Conclusion**

The smelters and refiners listed in Appendix I represent the source of 3TG used in our products or production process according to our due diligence. The third-party audits supporting the RMAP process, information our suppliers otherwise obtain and report in their CMRTs, and RCOI data provided by the RMI, establish our best understanding of the source of minerals further upstream for smelters and refiners. Although supplier disclosure indicates that certain 3TG used in our products originates from Covered Countries, we are unable to confirm whether any of these materials are linked to armed conflict or human rights abuses. This determination remains inconclusive for the current reporting year. Through the ongoing progress of our due diligence efforts each year, we aim to reduce this risk. Given the large number of smelters in our supply chain that are RMAP conformant, as well as our overlap with companies capable of conducting upstream due diligence from smelters and refiners, we have found no evidence that sourcing in our supply chains directly or indirectly benefits armed groups.

**VIII. Due Diligence Process Improvement Efforts**

We plan to continue improvement efforts within our conflict minerals program, due to the level of complexity of our products, our downstream position in the supply chain, and continuing risk of conflict minerals. 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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b.Examine our support instruments to further refine the process for conducting follow-up with our surveyed suppliers to more effectively resolve incomplete, inaccurate or outdated responses in their surveys.
