SEPTENI HOLDINGS CO., LTD. (Headquarters: Shinjuku-ku, Tokyo; Representative Director: Yuichi Kouno; Securities Code: 4293) has entered into a share transfer agreement with Mediahouse Holdings Co., Ltd. (Headquarters: Shinjuku-ku, Tokyo; Representative Director, President and CEO: Keisuke Hatouchi; hereinafter "Mediahouse Holdings"), a company operating businesses such as corporate recruitment support and marketing support, to acquire its shares and make it a consolidated subsidiary. Moving forward, by combining the strengths of both companies, we will aim to further enhance our presence in the HR market, including performance-based job advertising, as well as in the digital marketing market.

The Septeni Group advocates "VALUE MAXIMIZER" (a partner that maximizes client corporate value) as its mid- to long-term vision. In the Medium-Term Management Plan (FY2026-2028) announced in February 2026, we set "Deepening Businesses" as one of our basic policies, aiming for further business expansion through the creation of Synergy & Collaboration in existing businesses. In addition, under "Exploring Businesses," we position accelerating investment in future revenue pillars as a key initiative.

Under these policies, in our core Marketing Communication Segment, we provide integrated marketing services centered on digital advertising, primarily to enterprise companies, striving to deepen our comprehensive DX support capabilities for corporations. Furthermore, capturing market shifts such as the transition toward performance-based job advertising against the backdrop of structural labor shortages and the acceleration of recruitment DX in Japan, as well as anticipating the further growing importance of HR marketing in the upcoming AI era, we have been seeking proactive investment opportunities with the aim of commercializing the HR marketing area. In recent years, we have been working to further strengthen our client support capabilities by combining job aggregator operational support—leveraging our rich track record and know-how built up through digital advertising operations—with HR DX that improves recruitment and training experiences through the power of technology.

Mediahouse Holdings holds the mission "To vitalize SMB across the nation," operating businesses such as the HR Tech Business centered on recruitment support and the Mar Tech Business handling web marketing. Mediahouse Holdings possesses a client base backed by its long-standing track record in supporting small and medium-sized enterprises (SMBs) and considers providing comprehensive solutions as its major strength, earning high external recognition primarily from job aggregators.

Upon signing this agreement, both companies have set forth a collaboration philosophy: "By combining the potential of talent and solutions of both companies, and by jointly taking on the challenge of creating further business value, we will lead a period of transformation in the HR market and the digital marketing market, thereby inspiring Japan." Under this philosophy, by bringing together the strengths of both companies moving forward, we aim to maximize our proposal capabilities and purchasing power for clients in performance-based job advertising. Simultaneously, through mutual complementation between Mediahouse Holdings' client base of SMBs and extensive sales network and our Group's existing client base centered on enterprise companies, we will focus on building a solid business foundation.

Through creating such multifaceted synergies, we will accelerate the expansion of the HR marketing area set forth in the Medium-Term Management Plan, striving to realize the maximization of client corporate value as a VALUE MAXIMIZER.
