Notice Regarding Company Split (Simplified Absorption-Type Company Split) of Tsukuba Lease Corporation

Tokyo, Japan – April 13, 2026 – ORIX Corporation (“ORIX”) announced today that it has decided to implement an absorption-type company split (the “Company Split”), whereby ORIX and ORIX Auto Corporation (“ORIX Auto”), a consolidated subsidiary of ORIX, will act as the absorbing split successor companies (the “Successor Companies”), and Tsukuba Lease Corporation (“Tsukuba Lease”), a consolidated subsidiary of ORIX, will act as the absorbed split company (the “Split Company”). ORIX has also decided that, following the effectiveness of the Company Split, Tsukuba Lease will be dissolved and liquidated. The business currently operated by Tsukuba Lease will be continued by the Successor Companies after the Company Split.

As the Company Split is implemented as a simplified absorption-type company split involving ORIX’s consolidated subsidiary, ORIX is omitting certain disclosure items and details in this notice.

1. Purpose of the Company Split

The Company Split aims to enhance operational efficiency and effective utilization of management resources through a management integration within the ORIX Group, taking into account the future growth prospects of Tsukuba Lease. Tsukuba Lease is expected to be dissolved and liquidated following the Company Split.

Notes:

-	The Company Split qualifies as a simplified absorption-type company split pursuant to Article 796, Paragraph 2 of the Companies Act of Japan, and therefore no shareholders’ meeting pursuant to Article 795, Paragraph 1 of the Companies Act of Japan will be convened by ORIX.

Because ORIX holds 90% or more of the voting rights of Tsukuba Lease and therefore has a special controlling relationship with Tsukuba Lease, the Company Split between ORIX and Tsukuba Lease qualifies as a short-form absorption-type company split pursuant to Article 784, Paragraph 1 of the Companies Act of Japan, and no shareholders’ meeting will be convened by Tsukuba Lease.

-	The dissolution and liquidation of Tsukuba Lease will be carried out sequentially after the effective date of the Company Split.

ORIX and ORIX Auto plan to pay, as consideration for the absorption-type company split, the valuation of Tsukuba Lease’s lease receivables and installment receivables business as of July 31, 2026. In determining such consideration, the valuation shall be calculated and determined based on their book value.
