Seoul Gazette - ADK Group Enters into a Three-Year Strategic Business Partnership with Stagwell

NEW YORK CITY, NY / ACCESS Newswire / October 13, 2026 / ADK Holdings Inc. (Headquarters: Minato-ku, Tokyo; Representative Director and President: Toshiya Oyama) has entered into a Master Agreement for a three-year strategic business partnership with Stagwell Inc. (Headquarters: New York, USA; Chairman & CEO: Mark Penn; hereinafter "Stagwell" (NASDAQ:STGW)).

This partnership aims to maximize the value delivered to clients in both the Japanese and global markets by leveraging the complementary capabilities and global networks of the two companies.

By combining the comprehensive capabilities and trust that the four core ADK Group companies (ADK Holdings, ADK Marketing Solutions, ADK Creative One, and ADK Emotions) have cultivated in the Japanese market over many years with Stagwell's marketing service capabilities powered by world-class technology and its global network, the two companies will fully launch a comprehensive support framework to solve clients' marketing challenges in Japan and around the world.

From One Year of Collaboration to a Three-Year Strategic Business Partnership

Under the Memorandum of Understanding on promoting global collaboration signed in July 2025, the two companies have spent approximately one year validating the effectiveness of their collaboration through a variety of joint projects. These efforts have produced results across multiple areas, including supporting the global expansion of IP originating in Japan and helping major Japanese corporate clients expand overseas.

The signing of this Master Agreement marks a formal transition from the previous project-based cooperation to a stable, three-year strategic collaboration framework.

Key Focus Areas for Collaboration

With the signing of the Master Agreement, the two companies have designated the following two areas as key focus themes for their collaboration.

Expanding IP business in global markets, starting with the United States

By combining ADK's global IP production capabilities, grounded in its marketing expertise, with Stagwell's U.S. entertainment data and analytics capabilities and comprehensive marketing execution capabilities, the two companies will drive, end to end, the North American expansion of Japanese IP and the creation of joint businesses in Japan and overseas.

Strengthening support for global and multinational brands in the Japanese market

Working with the global network of Stagwell, which has numerous highly specialized marketing companies under its umbrella, the two companies will build optimal solutions and support structures to help multinational brands enter and grow their businesses in the Japanese market.

Ongoing Areas of Collaboration

• Supporting Japanese companies' marketing activities targeting global markets
• Enhancing services in Japan and overseas through the shared use of both groups' data assets, tools, and solutions

In addition, by mutually assigning resources in the target areas and promoting ongoing exchanges of personnel, the two companies aim to build a strong alliance at both the organizational and personnel levels and to advance this strategic business partnership with a high degree of effectiveness.
