1. Purpose of the Transaction and Future Management Policy
The Company's basic strategy is to identify the products as its core business called the "Eight Spears" in which the Company can demonstrate its strength such as super-precision processing technologies and mass production technologies and which would not be easily eliminated from the market, and to provide the customers with new values by INTEGRATION*. Precision Technologies Business of the Company has not engaged with the Business to date, and the Company intends to expand its business by enhancing its product portfolio through the Acquisition.
TSUBAKI NAKASHIMA being the first company in Japan to produce and sell ball screws in 1959, the Business has high technological capabilities backed by the know-how accumulated over many years and has a wide range of product lineups that other companies do not possess, including ball screws and ball ways, and the products of the Business are used in a wide range of industries. We believe that the Business can be developed as a new pillar of our Precision Technologies Business, and that the Acquisition will lead to the maximization of our enterprise value by adding the Business to our product portfolio as core businesses that can create synergies with the Eight Spears.
The ball screw industry has a global market size of more than 200 billion yen, and we believe that it is an attractive market that can be expected to continue to grow with the increasing demand in a wide range of fields, including semiconductor manufacturing equipment and industrial robots, which are expanding at a high growth rate, as well as medical equipment and logistics and transportation machinery. By actively utilizing the MinebeaMitsumi Group's resources such as a variety of technologies and global sales network, etc., the Company aims to expand the current market share of the Business and improve its market position.
- *1 "Integration": This term was adopted with the intended meaning "to be combined" rather than "to sum up".
Create new value through synergy by combining all the resources of our group.
