Rigaku Group’s Policy
The Rigaku group of companies is concerned about the significant social issues related to extraction of mineralssuch as tin, tantalum, tungsten, gold and cobalt, which can lead to funding of conflicts and causing human-rights
violations such as child labor or poor working conditions in conflict-affected countries and high-risk areas. To
fulfill our social responsibility, we promote responsible mineral procurement through our whole supply chain.
To promote specific efforts about these responsible mineral procurement, we are committed to the followingactivities.
•Based on OECD Due Diligence Guidance※1, we manage and conduct our supply chain appropriately.

•We use the survey of the industry standard RMI※2 (Responsible Minerals Initiative) and conduct a survey
and risk assessment going back through our supply chain in cooperation with primary purchasers.

•We request you, our suppliers, to procure minerals from compliant smelters/refiners based on RMAP※3(Responsible Minerals Assurance Process)•If we identify risks, we will implement corrective measures.

•Based on Section 1502 of Dodd-Frank, as a company involved in the supply chain of the US SEC registeredcompanies, we disclose appropriate information regarding conflict minerals and other high-risk minerals byreporting to our customers based on our assessment of the supply chain.

Responsible Mineral Procurement Survey
Rigaku group of companies conducts surveys about conflict minerals with our business partners.
We use RMI survey (CMRT: Conflict Minerals Reporting Template). We analyze risks based on the CMRT returnedby our suppliers. We request further information when we judge there are risks, for example in the case thatsmelters/refiners are not in conformity with RMAP.
In case minerals involved in conflicts are found in supply chain, we request you to avoid using them by taking
measure such as seeking an alternative supplier.
We also conduct supply chain survey using RMI survey (EMRT: Extended Minerals Reporting Template) andspecifying/investigating refine/refiners about other minerals such as cobalt, which have created concerns abouthuman rights issues including child labour.
