Basic Approach
The MinebeaMitsumi group's business is supported by relationships with numerous partners. Our group has adopted the "Basic Procurement Policies" and building a healthy partnership based on these. In order to promote CSR throughout our supply chain, we distribute the "MinebeaMitsumi Group CSR Procurement Guidelines*" to our partners and are striving to facilitate their understanding and cooperation.
We are creating a framework for global CSR procurement in order to promote CSR throughout our global supply chain.

MinebeaMitsumi Group CSR Procurement Guidelines
Considering the global scope of our group's business activities, we believe it is important to promote CSR throughout our supply chain. In March 2012, we took steps to establish a framework for CSR procurement with the formulation of the "MinebeaMitsumi Group CSR Procurement Guidelines" based on the "MinebeaMitsumi Group Code of Conduct*."
The "MinebeaMitsumi Group CSR Procurement Guidelines" is available in Japanese, English, and Chinese version and revised as necessary. When the Guidelines are revised, we distribute it to partners around the world and ask for their understandings and cooperation again.

Operation of CSR Procurement
We established the "MinebeaMitsumi Group CSR Procurement Self-Check Sheet"* in 2013 and have asked our partners to complete it. We upgraded the checklist in August 2025. Two new categories "Anti-Corruption", and "Action Against Prohibited Conduct" were integrated into five existing categories "General Promotion of CSR", "Human Rights・Labor", "Health and Safety", "Environmental Conservation", "Ethics and Business Practice" to assess risks in the supply chain. In addition to providing feedback of the results to our partners, we investigate the cause of any issues when the results do not meet with our requirement, and after consultation with the partner, we prepare for specific countermeasures. By communicating individually, we are able to confirm the subsequent improvement situation in detail.
To date, there have been no serious compliance violations that conflict with the "MinebeaMitsumi Group CSR Procurement Guidelines."

Before starting business with our partners, we confirm:
- whether we can do business continuously
- whether they can agree and cooperate with us on our CSR Procurement Guidelines.
- whether they can comply with our Green Procurement Standard, etc.
After confirmation, we conclude a basic transaction agreement and aim to improve CSR activities with our partners.
In order to promote initiatives across the entire supply chain, we make requests similar to those in our CSR Procurement Guidelines to our partners' supply chains, and ask them to confirm the status as appropriate.
Expansion of CSR Procurement
Considering the human rights movements in the world and for promoting our company's policy of "Responsible Procurement," we acquired agreements on the following three items regarding "Human Rights and Labor" from 4,698 partners around the world.
From 2021, it is essential for us to obtain the Letter of Commitment from a partners to start business. In FY2025, following the revision of the CSR Procurement Guidelines, we confirmed that this initiative is being continuously maintained across the entire group.
- A promise to comply with the requirements set forth under MinebeaMitsumi's "CSR Procurement Guidelines":
(1) Freely Chosen Employment, (2) Prohibition of Child Labor, (3) Prohibition of Discrimination,
(4) Prohibition of Harsh or Inhumane Treatment, (5) Minimum Wages, (6) Working Hours, and
(7) Freedom of Association - Request that your supply chain comply with the "CSR Procurement Guidelines" established by our company.
- There are no violations by your company or your supply chains, and if any violations are discovered, they must be reported to us without delay.
Activities on CSR Procurement
In 2025, along the revision in "MinebeaMitsumi Group CSR Procurement Guidelines", the "MinebeaMitsumi Group CSR Procurement Self-Check Sheet" was updated; questions regarding "Environmental Conservation" were revised and questions regarding "Anti-Corruption" and "Action Against Prohibited Conduct" were newly added.
And we reviewed and revised the questions regarding "General Promotion of CSR" in the "MinebeaMitsumi Group CSR Procurement Self-Check Sheet" to grasp further detailed status of CSR promotion.
With this revised latest version of the "MinebeaMitsumi Group CSR Procurement Self-Check Sheet," the survey was conducted among 267 key partners of Mitsumi Electric, Minebea Power Semiconductor Device, and Minebea Cambodia and gained 100% response rate.
As a result of reviewing their answers, we identified 45 partners were to be improved, and requested corrective measures. We will continue monitoring their progress periodically until these corrective measures are completed.
Procedures for Conducting the "MinebeaMitsumi Group CSR Procurement Self-Check Sheet"
The MinebeaMitsumi Group grasps the progress of CSR promotion among its partners for the purpose of conducting risk assessments within the supply chain.
Focusing on partners that supply critical materials and components for our group's operations, and based on a comprehensive assessment of partners with significant purchase amounts, we define such partners as "key partners". Each fiscal year, we select applicable partners based on the following standard and request that they complete the "MinebeaMitsumi Group CSR Procurement Self-Check Sheet".
| Premise: | "MinebeaMitsumi Group CSR Procurement Guidelines" shall be provided to partners |
|---|---|
| Scope: | Each fiscal year, applicable bases are designated among MinebeaMitsumi Group, and applicable partners are selected based on a threshold of around 70% of that base's total purchase amount from the previous fiscal year. |
* Items "V. Anti-Corruption", and "VI. Action Against Prohibited Conduct" were added in FY2025
* Items scoring less than 100 points in each category listed below are regarded to be improved.

Participation in Supply Chain Subcommittee
We express our support to the United Nations Global Compact (hereinafter "UNGC") and participate in the subcommittee regarding supply chain hosted by GCNJ (Global Compact Network Japan) that is a Japanese external body of the UNGC.
We continue to strive for fair transactions with our partners and promote CSR activities in the supply chain.
Promotion of Local Procurement
We promote local procurement to realize "Work in harmony with the local community" and "Promote and contribute to global society" defined in our company credo "The Five Principles" through our procurement activities.
For example, our purchase from local partners exceeds 50% in Thai Factory, which is our largest production site.
Partners Selection Policy
Whenever our group initiates a relationship with a new partner, we ask them to agree with our group's approach to materials procurement and we check new partners in accordance with certification standards to ensure compliance with our Basic Procurement Policies. Specifically, we confirm whether partners: can conduct business with us in a stable and continuous manner, can comply with our group's guidelines and standards on chemical substances in products, and can agree with "MinebeaMitsumi Group CSR Procurement Guidelines." If needed, we conduct the audit of partners' production facilities.
CSR Procurement (move to company site)
Compliance with Subcontract Act of Japan
To ensure the establishment of fair and equitable trading relations with partners, our business sites implement self-auditing and conduct training on the Act annually.
We conduct self-audits to confirm the situation and strive to improve. In FY2025, we implemented the self-auditing at our 31 business sites.
Furthermore, in FY2025 we conducted the training online with 2,657 participants, and all of the participants passed the comprehension test (100% completion among the intended emmployees).
Environmental initiatives
Our Group considers the conribution to the realization of global carbon neutrality by 2050 as one of our missions. We are striving to reduce our own greenhouse gas emissions and ensure our products help customers reduce their greenhouse gas emissions.
We recognize that the engagement to strengthen and expand greenhouse gas emissions reduction should be promoted across the entire supply chain. Therefore, the survey has been launched in FY2024 to assess the status of our partners' greenhouse gas emmission reduction efforts. And we will continue to conduct the survey going forward.
In addition, we are launching an e-learning program for our key partners starting in FY2026 to promote awareness and understanding of climate change mitigation.
Green Procurement
We have established and revised the guidelines and standards on chemical substances in products to ensure compliance with countries' laws and directives on chemical substances, to improve the level of customer satisfaction, and to reduce the use of substances having an environmental impact. Under these guidelines, we request our partners to provide products (raw materials, components, and packaging materials) that are free of hazardous substances, and also to submit safety certifications, reports of analysis results, and other similar documentation.

Response to Responsible Minerals Procurement
In response to the disclosure rules of the Financial Regulatory Reform Act adopted by the U.S. Securities and Exchange Commission in August 2012, which requiring companies to disclose the use of conflict minerals from Democratic Republic of the Congo and its neighboring nations, we formulated the "MinebeaMitsumi Group Policy on Conflict Minerals*" in October 2012 and integrated "conflict minerals compliance" into the "MinebeaMitsumi Group CSR Procurement Guidelines." Afterwards, our group reviewed the Guidelines in consideration of recent global trends regarding responsible minerals procurement in recent years.
Today, we are promoting these efforts under the revised name of the "MinebeaMitsumi Group Responsible Minerals Procurement Policy." Specifically, we are driving initiatives toward the non-use of minerals associated with conflict and CSR risks—including tantalum, tin, tungsten, gold, and cobalt—and are requesting our business partners to do the same.
Additionally, we continue to respond to research requests from customers by providing a response using our research database.
