Announcement of the launch of new company "Ryosan Ryohyo Corporation" through integration

Ryosan Corporation and Ryohyo Electro Corporation have merged and will embark on a new start as "Ryosan Ryohyo Corporation."

1. Purpose of this integration While focusing on "improving productivity" to expand the absolute volume of customer touchpoints and strengthen the mechanism for understanding needs by leveraging the management resources cultivated by both companies over their long histories, "creating integrated synergy" through focused initiatives based on the strengths of both companies, and "creating uniqueness" by establishing and strengthening competitive know-how, we have decided to merge to further accelerate these efforts.

By consolidating management resources such as customers, products, information, technology, and human resources into a single business company, we will promote initiatives that lead to the resolution of issues faced by customers and the market as a whole, not only through streamlining management and reducing costs but also by further expanding customer touchpoints.

Regarding what kind of value our group will create and what kind of vision we aim for through this integration, we have organized it in our "Promise Book," compiled as our commitment to our customers. Details can be confirmed below.
