Notice Regarding Possible Impact on ORIX Corporation’s Consolidated Financial Results (First Quarter of the Fiscal Year Ending March 31, 2027), Following Toshiba Corporation’s Full-Year Financial Results for the Fiscal Year Ended March 31, 2026

Tokyo, Japan – May 15, 2026 – ORIX Corporation (“ORIX”) announced today that, based on the contents of the full-year financial results for the fiscal year ended March 31, 2026, released today by Toshiba Corporation (“Toshiba”), ORIX expects that there will be an impact on its consolidated financial results for the first quarter of the fiscal year ending March 31, 2027.

In Toshiba’s full-year financial results for the fiscal year ended March 31, 2026*, Toshiba recorded the income related to Kioxia Holdings Corporation amounting to ¥2,277 billion.

ORIX indirectly holds a portion of Toshiba’s shares through TB Investment Limited Partnership (the “Partnership”), an equity-method affiliate of ORIX. The Partnership’s financial results for the fourth quarter of the fiscal year ended March 31, 2026, as well as the income related to Kioxia Holdings Corporation, are expected to be reflected in ORIX’s consolidated financial results for the first quarter of the fiscal year ending March 31, 2027.

The impact of the inclusion of Toshiba’s financial results on “Net Income Attributable to ORIX Shareholders” in ORIX’s consolidated financial results for the full fiscal year ending March 31, 2027, is currently under detailed review. If the impact of the gain on the sale of securities and the valuation gain subsequently becomes reasonably estimable, ORIX will make an announcement accordingly.
