MITSUBA Corporation is pleased to announce that it has been selected as a constituent of the FY2026 JPX-Nikkei Mid and Small Cap Index, an index jointly calculated by JPX Market Innovation & Research, Inc. and Nikkei Inc.

2. About the JPX-Nikkei Mid and Small Cap Index

The JPX-Nikkei Mid and Small Cap Index applies the concept of the JPX-Nikkei Index 400, which consists of companies considered highly attractive to investors, to the universe of mid-and small-cap stocks. The index aims to identify ompanies that effectively utilize capital and practice management with a strong awareness of shareholder and investor interests.

3. Significance of Our Selection

We believe that our inclusion in this index reflects recognition, based on established criteria, of our efforts in areas such as profitability, capital efficiency, corporate governance, and information disclosure.
Unlike indices that simply represent overall market performance, the JPX-Nikkei Mid and Small Cap Index selects companies from among mid- and small-cap stocks that are committed to investor-oriented management and improving capital efficiency. We therefor regard our inclusion as an objective indicator of our ongoing efforts to enhance corporate value.

4. Future Initiatives

MITSUBA Corporation will continue to place importance on constructive dialogue with shareholders and investors and will remain committed to achieving sustainable growth in corporate value.
