3. Value Creation Model of MinebeaMitsumi

MinebeaMitsumi’s three strengths are “Reinforcing Core Businesses,” “Diversified Niches,” and Sustainable growth based on three strengths “Generating Synergies through the INTEGRATION*.”

By refining these three strengths and generating synergies, we have created environmental and social and non-financial capital value at the same time as economic value, thereby accumulating both financial and non-financial capital.

Using all such capital, we will further hone our three strengths to realize sustainable growth. * INTEGRATION means “combining” rather than “simple gathering” of the Company’s proprietary technologies to evolve the “Eight Spears” and to create new products in various fields through the INTEGRATION of our advanced technology.

● Corporate Philosophy To contribute to society by “Producing better products, with faster speed, in larger numbers, at lower cost and by smarter means.” We create environmental value, for example through the supply of environmentally considerate products such as ball ● Basic management policy bearings that reduce friction and increase energy efficiency. We also create social value through means such as raising Transparent management based on our company credo “The Five Principles” awareness of agricultural workers in emerging countries and encouraging their participation in the latest technology fields. In this way, we achieve business activities that harmonize the resolution of social issues with the creation of economic value. ● Corporate strategy Through these activities, we aim to realize the SDGs promoted by the United Nations. Create new value through “difference” that transcends conventional wisdom
