Notice regardingExecution of Share Purchase Agreement

TOKYO, Japan — November 11, 2022 — ORIX Corporation (“ORIX”) announced today that it has executed a share purchase agreement with Mr. Yoshiaki Yoshida, who is a major shareholder of DHC Corporation (“DHC”), and has reached a basic agreement to acquire the shares of DHC. Along with procedures for the share acquisition, ORIX will further proceed with discussions with other shareholders of DHC to acquire their shares of DHC, among others. ORIX will issue another announcement about the details of the share acquisition once they are finalized.

1. Background of Execution of Share Purchase Agreement

DHC has many years of experience as a major leading cosmetics and health food company. Through its proactive PR activities on television and mail-order sales business, DHC has become well known within Japan and supported by people across many age groups. In addition to its mail-order sales, DHC has broad range of sales channels, such as its own directly-operated stores, convenience stores, and drug stores.

Cosmetics and health foods play a role in supporting the healthy lives of people. Moreover, following the rise in health awareness due to the coronavirus pandemic, stable demand is expected to continue in the future. ORIX focuses on health care business through its investment in INNOMEDICS Medical Instruments, Inc., a medical equipment sales company (head office: Bunkyo-ku, Tokyo), and DOJIN IYAKU-KAKO Co., Ltd., a pharmaceutical company (head office: Nakano-ku, Tokyo). This share acquisition will contribute to network expansion in healthcare fields for the ORIX Group.

Capitalizing upon the expertise it has cultivated over many years in improving investee value, ORIX will promote a smooth business succession for DHC and further strengthen the company’s compliance management system and corporate governance. Mr. Yoshiaki Yoshida, who is the Chairman and President of DHC, will resign from his position after completion of the share acquisition. Under a new management structure, DHC will continue to contribute to various stakeholders including its customers and clients, and act for the realization of a sustainable society.
