The Resonac Group positions its semiconductor and electronic material business as a core-growth business in its business portfolio, and has been conducting a thorough reform of its investment policy in order to concentrate its investment on semiconductor and electronic material business.  To promote this reform into the right direction speedily, Resonac’s management team requires participation of capable person who has expertise in the semiconductor industry and experience in management of global business operation.  In this context, Resonac decided to invite Mr. Tsuneishi to be its Outside Director.  Mr. Tsuneishi joined Tokyo Electron Ltd. in 1976, became Director of Tokyo Electron Ltd. in 1992, and participated in the management team of the semiconductor manufacturing equipment company for many years.  Thus, Mr. Tsuneishi has rich expertise in global management and the semiconductor industry.  Resonac believes that Mr. Tsuneishi’s participation in the management team will increase Resonac’s corporate value and strengthen its management power.



Comment by Tetsuo Tsuneishi, Outside Director

Resonac has a long history of about one hundred years since its foundation.  In recent years, Resonac has been promoting selection and concentration of business operations, reviewing its business portfolio, executing bold mergers and acquisitions, and focusing its management resources on semiconductor and electronic material business which creates high added value.  I have been paying attention to Resonac because the company also continues strengthening competitiveness of its conventional products with leading technologies and enhancing the company’s true corporate value through groupwide courageous challenge.  I would like to contribute to growth of the company  which aims to win through in the global competition and desires to be rated high in the global capital market.


Comment by Hidehito Takahashi, President and CEO

Since January 2023, Resonac has been promoting structural reform to position its semiconductor material business as a central field that supports growth of the company.  I believe Mr. Tsuneishi’s excellent judgement nourished through his rich experience in the semiconductor industry and sincere effort to enhance corporate value are indispensable for Resonac’s success in this reform.  Therefore, I’m sure his inauguration of this time will strengthen Resonac’s management power directly.  I’m looking forward to having lively discussion at the Board of Directors’ meetings.
