Mitsui & Co., Ltd. ("Mitsui", head office: Tokyo, President and CEO: Kenichi Hori) has resolved at the Board of Directors meeting held today that the outcome from carrying out a review of its material issues (materiality), in which the key management issues for the sustainable growth of both society and Mitsui are defined.

Our corporate activities are closely linked to our materiality, identified in pursuit of our Mission, "Build brighter futures, everywhere."

We originally defined five material issues in 2015. The first review of our materiality took place in 2019, and now we have conducted a further review to ensure that our recognition of social issues is in line with the ever-changing operating environment.

In this review, we have identified key social issues and evaluated their significance through ongoing dialogue with a wide range of stakeholders, while incorporating the perspective of double materiality*. Based on these evaluations, we engaged in both internal and external discussions, including with external experts, External Directors, and External Audit & Supervisory Board Members, and surveying employees and officers. As a result, we identified six material issues which were discussed and subsequently approved by the Executive Committee and the Board of Directors. Notably, as a result of this review, we added a new standalone material issue related to human rights. We have long regarded consideration for human rights, in accordance with international standards, as the foundation of our sustainability management and have actively pushed forward initiatives to respect human rights. Therefore, while human rights were recognized as an important social issue in our latest materiality, through dialogue with stakeholders, we confirmed that the importance of conducting business based on the premise of respecting human rights has further increased. Considering this, we have clarified our stance and efforts regarding the human rights of people involved in our corporate activities. Going forward, we will continue to review our approach as needed, taking into account factors such as changes in the operating environment, to ensure that we address social issues relevant to the times.
