Under the agreement, Teijin Frontier will absorb Asahi Kasei Advance through a merger scheduled to take effect on 1 October 2026, pending regulatory approvals from authorities including the Japan Fair Trade Commission. Following the integration, Teijin Frontier will become a joint venture majority-owned by Teijin (80%) with Asahi Kasei holding a 20% stake.

Strategic objective: Complementary strengths and greater scale

According to the release, the integration aims to “achieve sustainable growth and maximize corporate value” by combining the business foundations, customer networks, and market strengths of both companies. The merged entity intends to create value through:

• Expanded cross-selling opportunities across global markets
  

• Integrated value chains to reduce procurement costs and improve supply stability
  

• Faster product development cycles and enhanced competitiveness in domestic and overseas markets
  

The companies highlight that the new organization will be positioned to deliver “sustainable value” with a stronger foundation for long-term growth.

Shareholders of Asahi Kasei Advance will receive 5,000,500 shares of Teijin Frontier stock in total, based on an integration ratio of 20,001 to 5,000,500 shares.
