Shiga Bank, Ltd. underwrote our SDGs private placement bond “Tsunagari,” and
a presentation ceremony was held at the University of Shiga Prefecture on March 30.

Using a portion of the fees from issuing this private placement bond, we donated our vacuum
pump to the University of Shiga Prefecture jointly with Shiga Bank, Ltd.

We hope it will be useful for the university’s research activities.

Our company will continue to support educational institutions that nurture the next generation
of leaders.
