Notice of Non-Fossil Certificate Purchase from Himawari Green Energy Co., Ltd.

Sony Bank Inc. (President and Representative Director: Keiji Minami / Headquarters: Chiyoda-ku, Tokyo / hereinafter "Sony Bank") announces that on Friday, February 27, 2026, it purchased approximately 460,000 kWh of FIT non-fossil certificates from Himawari Green Energy Co., Ltd. (President and Representative Director: Toshihiko Honjo / Headquarters: Chiba City, Chiba Prefecture / hereinafter "Himawari Green Energy"), a subsidiary of Chiba Bank engaged in renewable energy generation and sales.

FIT non-fossil certificates certify the "environmental value" portion of electricity generated from non-fossil power sources (such as solar, wind, and biomass renewable energy, which do not emit CO2 during generation) covered by the FIT scheme (Feed-in Tariff system for renewable energy), and can be used to reduce CO2 emissions from electricity consumption.

Himawari Green Energy registered as a non-fossil value trading member with the Japan Electric Power Exchange (JEPX) in March 2024 to conduct brokerage services, and has since commenced its brokerage business for FIT non-fossil certificates.

As a sustainability collaboration initiative through its business alliance with Chiba Bank, Sony Bank has been purchasing non-fossil certificates from Himawari Green Energy since fiscal year 2024, and this marks the second such purchase. The FIT non-fossil certificates purchased through Himawari Green Energy will be used to effectively make 100% of the electricity consumed at Sony Bank's offices renewable, contributing to CO2 reduction.

Going forward, both banks will continue to promote initiatives such as mutual provision of digital technologies and products/services, joint research on technology utilization, and the creation of new products and services, while also collaborating on sustainability activities.

Sony Bank also aims to contribute to the achievement of the SDGs (Sustainable Development Goals) through value creation in its banking business and through strengthening the foundation for value creation.
