Decarbonizing the SEGA SAMMY Group Headquarters withRaw Green Power from Newly Established Power Plants
First in Japan to adopt the “Sunlight Premium” plan forenvironmentally advanced companies

SEGA SAMMY HOLDINGS INC. (hereinafter “SEGA SAMMY Group”), Sumitomo Realty & Development Co.,
Ltd. (“Sumitomo Realty”), and TEPCO Energy Partner, Inc. (“TEPCO EP”) are pleased to announce the creationof a scheme to power the tenant areas of office buildings with raw green power*1 from newly established solar
power plants, thereby making direct contribution to raising the total amount of renewable power supply in Japan.
The scheme will be used to power the office areas of the SEGA SAMMY Group headquarters.
The SEGA SAMMY Group has thus far substantially reduced its energy consumption through energy-saving
initiatives and the consolidation of business bases into an office building with high environmental performance.
Moreover, aiming to conserve the environment and further reduce CO₂ emissions, the SEGA SAMMY Group,with the cooperation of Sumitomo Realty and TEPCO EP, has decided to become the first company in Japan toprocure raw green power with additionality*2 utilizing TEPCO EP’s Sunlight Premium plan for environmentallyadvanced companies.
By applying non-fossil fuel energy certificates to cover the hours when solar power is unavailable, such as
during the night, virtually all electricity used at the SEGA SAMMY Group headquarters will be powered withgreen power. The implementation of this scheme is scheduled for December 2021.

supply with additionality*1. Raw green power➡ Refers to green power considered as being directly supplied from the power plant via general-use power grids; the generationand consumption of raw green power are matched in 30-minute units.
*2. green power with additionality➡ Refers to green power obtained by developing new renewable power sources such as new solar power plants, and therefore
directly contributing to raising Japan’s total renewable power generation capacity. In recent years, additionality has been
considered a requirement for high-value renewable electricity and used by environmentally advanced companies in Europe andthe US as a standard for selecting green power.

Background to introducing Sunlight Premium
In 2018, the SEGA SAMMY Group successfully reduced over 30% of its energy consumption by consolidating
the business bases of 20 group companies, including SEGA SAMMY HOLDINGS, SEGA and Sammy, into theSumitomo Fudosan Osaki Garden Tower, an office building known for its high environmental performance. At
this time, the Group, which aims for sustainable management focused on the keywords of Environment,Empathy, Edge and Economics, requested Sumitomo Realty’s cooperation in pursuing environmental
conservation and further reducing CO₂ emissions, and discussions toward adopting the Sunlight Premium
plan began.
Previously, office buildings for lease in city centers typically used non-fossil fuel energy certificates todecarbonize, and it was considered difficult to introduce raw green power with additionality to the tenant areasof these buildings and achieve high-value decarbonization that directly contributed to raising Japan’srenewable power supply. In light of SEGA SAMMY Group’s strong determination, however, Sumitomo Realty
and TEPCO EP decided to plan and develop the means to bring in raw green power with additionality to tenant
areas, leading to introduction of the Sunlight Premium plan to power the SEGA SAMMY Group headquarters,
and effectively achieving 100% green power combined with the use of non-fossil fuel energy certificates.

About the Sunlight Premium planCompanies actively working to achieve decarbonization exhibit rising needs not only to utilize existing
renewable power sources but to seek additionality in which their purchase of and investments in renewableenergy promote the development of new renewable power sources.
With the Sunlight Premium plan, TEPCO EP will respond to customer needs by initially building several
small solar power facilities to deliver solar electricity and environmental value to its customers. By adopting theplan to cover a portion of the electricity being used, customers can reduce their CO₂ emissions and at thesame time contribute to the growth of renewable energy in Japan.
Sumitomo Realty and TEPCO EP’s agreement regarding projects to lead decarbonization
As companies underpinning the social infrastructure, Sumitomo Realty and TEPCO EP aspire to jointly design
the scenario for social transformation toward carbon neutrality in 2050 and lead Japan and the world in thiseffort. To this end, they concluded a business alliance agreement on September 1, 2021 to jointly plan andimplement decarbonization projects.
The adoption of raw green power with additionality at tenant leased areas of office buildings, explained
herein, was planned and developed as part of this agreement.
