Dexerials Corporation (Headquarters: Shimotsuke-shi, Tochigi, Representative Director and President: Yoshihisa Shinya, hereinafter, “Dexerials”) announced that it has been selected for the fourth consecutive year to be a constituent of JPX-Nikkei Index 400^*1, which is provided jointly by JPX Market Innovation & Research, Inc., and Nikkei Inc., and for the second consecutive year as a constituent stock of the “JPX Prime 150 Index”^*2, calculated by JPX Market Innovation & Research, Inc.

The JPX-Nikkei Index 400 is composed of companies with high appeal for investors, which meet the requirements of global investment standards, such as the efficient use of capital and investor-focused management perspectives. It was developed for the purpose of showcasing the appeal of Japanese companies both in Japan and overseas, encouraging them to enhance their corporate value in a sustainable way, and revitalizing the stock market.

The JPX Prime 150 Index is a stock index comprising companies positioned as “Japanese companies that are estimated to create value” and our company was selected for the first time in 2024. A total of 150 of the top 500 companies listed on the Tokyo Stock Exchange Prime Market, in terms of market capitalization, based on two measures of value creation, with 75 companies by “return on capital” , which is based on financial results, and 75 companies by "market valuation", which is based on future information and non-financial information. Capital profitability is measured using the equity spread, which is the difference between ROE^*3 and the cost of equity,^*4 while market valuation is indicated by PBR(Price-to-Book Value Ratio), calculated by dividing the share price by BPS(Book Value per Share).^*5 Dexerials was evaluated from an equity spread perspective.

Dexerials will continue to provide high value-added products, technologies, and solutions, which are essential for the evolution of digital technologies that help solve social issues, as part of its efforts to contribute to building a sustainable society, to achieve sustainable growth, and to further enhance its corporate value.
