Notice regarding Transfer of equity interest (change in subsidiary): IX PUSG Holdings, LLC (U.S. PE Investment: Peak Utility)

TOKYO, Japan – March 11, 2026 – ORIX Corporation (”ORIX”) announced today that one of its affiliates has entered into an equity interest transfer agreement on March 10, 2026 U.S. Time with a special purpose company (“The SPC”) affiliated with Greenbelt Capital Partners (”Greenbelt”) to transfer all of the equity interest in IX PUSG Holdings, LLC (“IX PUSG Holdings”) to Greenbelt.

1. Purpose of transfer of all equity interest

IX PUSG Holdings is the holding company for Peak Utility Services Group, Inc. (“Peak”), in which our company invested^*1 in 2018 through a fund managed by ORIX Capital Partners (“OCP”), the operationally-focused private equity team of our wholly owned subsidiary, ORIX Corporation USA. Peak was founded in 2002 and provides utility infrastructure services in the United States.

Since our investment, OCP has made significant contributions to Peak, including add-on acquisitions, organic growth initiatives, strengthening governance and operational improvements. Peak continues to deliver stable and strong performance, with revenue reaching a record high in the previous fiscal year.

As Peak has matured into a strong platform, OCP has determined that a new partnership is the logical next step for Peak to continue to grow into the future. Greenbelt, an Austin, Texas based private equity firm, which has extensive investment experience in energy and infrastructure, was identified as the optimal partner.
