Notice of Basic Agreement with Noah Construction Co., Ltd. for Battery Storage Business

We are pleased to announce that our company has decided to conclude a basic agreement for a business alliance regarding entry into and investment in the distributed battery storage business being developed by Noah Construction Co., Ltd. (hereinafter referred to as "Noah Construction").

1. Background and Purpose of the Partnership

In our growth strategy formulated in July 2025, our group has set forth "Aggressive Development of New Businesses" and "Proactive Promotion of Various Alliances (Business and Capital Partnerships)" as key policies, aiming to maximize corporate value and contribute to a sustainable society. As part of this initiative, with an eye toward evolving our "Environmentally Contributing Businesses" into a future pillar of growth, we have been exploring participation in the battery storage business to effectively utilize renewable energy and respond to electricity supply-demand adjustment needs.

Meanwhile, Noah Construction has been pioneering a "distributed battery storage business" that utilizes abandoned school facilities and sites to balance contributions to the local community with environmental considerations.

Through this partnership, our company will leverage Noah Construction's know-how and foundation in the distributed battery storage business to invest in and enter this business. This will enable us to contribute to the stabilization of the power grid while establishing a new revenue base for our company, thereby promoting mid-to-long-term enhancement of corporate value.
