steer Inc. (Headquarters: Chiyoda-ku, Tokyo; Representative Director: Kodai Sato; hereinafter "the Company"), which operates with the mission of "Creating towns, creating excitement, spinning aspirations" and develops diverse solutions for industries fundamental to "community development" with its agent business as its core, has concluded an official sponsorship agreement with the Yokohama DeNA BayStars for the 2026 season.

■ Background of the Sponsorship Agreement: "Excitement Creates Towns"

In the "community development" industry, which is directly linked to Japan's prosperity, the Company aims to realize a prosperous future by supporting highly specialized professional talent.

The "community development" as defined by the Company does not refer to a specific industry alone. It encompasses a comprehensive initiative that addresses social issues through the overlapping of a wide range of fields: local governments, infrastructure, energy, real estate, construction, finance, and sports and entertainment that generate "excitement."

Over the past 15 years of the Yokohama DeNA BayStars' journey, the atmosphere of Yokohama and the Kannai area has significantly transformed. The overwhelming vibrancy created by engaging not only the stadium but the entire town, injecting "excitement" into the whole area. This sight of "excitement creating towns" is the origin of the Company's deep dive into sports x community development.

We are honored to be able to present our brand on a stage representing Japan, Yokohama Stadium, and through this sponsorship, we will contribute to the further revitalization and development of the Yokohama region.
