Gunosy Inc. (Headquarters: Shibuya-ku, Tokyo; President and CEO: Kentaro Nishio; hereinafter "Gunosy") is pleased to announce that its consolidated subsidiary, Game8 Inc. (Headquarters: Shibuya-ku, Tokyo; Representative Director: Shunsuke Sawamura; hereinafter "Game8"), has entered into a business transfer agreement to acquire the business related to the smartphone app pre-registration service "Yoyaku Top 10" (Reservation Top 10) from Yoyaku Top 10 Inc. (Headquarters: Shinjuku-ku, Tokyo; Representative Director: Sho Yamada).

Starting April 1, 2026, the operational structure of this business has been fully transferred to Game8, and service has commenced under a new system as an asset contributing to the reinforcement of the revenue base in Gunosy Group's media business.

■ Background and Objectives of the Acquisition: Realizing "Seamless Support" from Pre-release to Post-release

Gunosy Group has positioned the re-growth of existing media businesses and the strengthening of revenue power as pillars of its management strategy. Game8, which operates one of Japan's largest comprehensive game information sites, began a business alliance with Yoyaku Top 10 Inc. in July 2025. Together, they have been developing a promotion model that provides one-stop support from app awareness acquisition and pre-registration to post-release operation.

Since the start of the alliance, by combining the expertise of both companies, steady results have been achieved in marketing support for publishers. To further accelerate decision-making and enhance the value of services provided, the decision was made to integrate the organizational structure through this business acquisition. This establishes a system capable of providing a consistent user experience from "pre-release to post-release," promoting the enhancement of media value across the entire group.

■ Improving Matching Accuracy through the Integration of Data Analysis and Operational Expertise

Following this acquisition, Game8 will accelerate the following initiatives:

1. Collaboration in Product Development:

Game8 will apply its expertise in operating one of Japan's largest media outlets and its data analysis infrastructure to "Yoyaku Top 10" to expand personalized reservation recommendation functions for individual users. This will provide users with opportunities to discover games of higher interest and offer clients more accurate promotion opportunities.

2. Maximizing Marketing Efficiency:

In the increasingly competitive smartphone game market where user acquisition costs are rising, Game8 will visualize the ROI of promotions by centrally utilizing data from reservation to gameplay. This will contribute diversely to the business growth of publisher companies.

■ Future Outlook: Enhancing Corporate Value through Re-growth of Existing Businesses

Through this acquisition, Gunosy will further solidify Game8's business foundation and strengthen the revenue structure of the entire group. Gunosy will continue to enhance the value of its existing businesses by deploying media operation expertise under the corporate philosophy of "Optimally delivering information to people around the world."

Gunosy Group aims to contribute to the sustainable development of the entire gaming industry and will continue to work together as a group to achieve this goal.
