Teijin Group traces its origins back more than 100 years, when it succeeded in the domestic production of rayon, an artificial silk thread, with the aim of making silk--then a highly expensive material--accessible to many people. Since then, the Group has continued its operations to this day by providing what is truly needed by society and earning its trust. This founding philosophy has been carried forward and remains deeply embedded within the Teijin Group today. The Group's purpose, "Pioneering solutions together for a healthy planet," reflects our commitment to sustainability, as it expresses our aim to provide solutions that help our planet and all life on it stay healthy.

In December 2025, Teijin Group established its Sustainability Policy: "We give back value to the global environment and society, contributing to the realization of a sustainable healthy planet." This policy demonstrates the Group's commitment to giving back value to the global environment and society through its business activities and to realizing the "Healthy Planet" set forth in its purpose. Through business activities that create both social and economic value, the Group aims to simultaneously enhance the sustainability of the global environment and society, as well as that of the Teijin Group itself.

Guided by this approach, the Group assesses its strengths, opportunities, and risks related to sustainability issues, including social and environmental challenges, and has identified five key issues to be addressed as priorities. By working together with customers, business partners, and other stakeholders to solve customer issues through its business activities, Teijin Group seeks to help address these key issues, create value for the global environment and society, while steadily advancing toward the realization of its long-term vision.

Teijin Group, under its purpose "Pioneering solutions together for a healthy planet," has established its Sustainability Policy: "We give back value to the global environment and society, contributing to the realization of a sustainable healthy planet." Based on this policy, the Group strives to achieve a "Healthy Planet," where our planet and all life on it stay healthy, while simultaneously enhancing the sustainability of both society and Teijin. Under the Sustainability Policy, the Group assesses opportunities and risks related to sustainability issues, including social and environmental challenges, and identifies its key issues (four Key Social Issues and one Key Management Issue). Furthermore, KPIs have been established for each key issue, and initiatives are being promoted through business activities.

• Materiality and KPIs

We have appointed a Chief Sustainability Officer (CSuO) as the person responsible for sustainability-related activities. Under the instruction and supervision of the Board of Directors, this officer promotes sustainability initiatives that are integrated with our business operations. Policies and key issues related to sustainability are matters to be resolved by the Board of Directors. In line with these policies, the executive side sets management indicators and implements initiatives, while progress and responses are reported as needed to the Board of Directors by the CEO or this officer for discussion. Furthermore, to ensure prompt and appropriate responses to sustainability issues, the newly established Sustainability Committee, under the leadership of the CEO, deliberates on sustainability policies and promotes initiatives.

We have organized the opportunities and risks the Teijin Group faces with the aim of contributing to the development of a sustainable world, and established a sustainable management base to promote sustainability initiatives. In order to implement the Teijin Group's sustainability initiatives in a unified and effective manner, a main division/organization in charge is specified under the supervision of the CSuO for each important sustainability issue. This main division/organization then starts the PDCA cycle of planning for the medium to long term and for single fiscal years (Plan), implementing this plan (Do), evaluating (Check), and improving (Action) to achieve ongoing improvement and enhancement of our sustainability initiatives.

Sustainability Awareness Raising Activities

Information dissemination on the internal communication platform

In addition to conducting lectures on sustainability for new employees and managers in level-based workshops, we are promoting internal awareness by regularly distributing sustainability-related content on Teijin HUB, a communication platform available to all Teijin Group employees. In FY2024, we distributed content on topics such as "Materiality and Non-Financial KPIs."

Sponsorship of the Envision Racing Formula E Team

• Partnership with Envision Racing Formula
  E Team

With its mission to "Race Against Climate Change," Envision Racing was the first team to receive carbon-neutral certification and promote the adoption of EVs and renewable energy. Since we share the team's vision and engage in similar activities, in 2020, we began our sponsorship with the aim of communicating the Teijin Group's corporate stance on climate change mitigation and adaptation to a wide range of global stakeholders. This partnership also seeks to increase awareness within the automotive industry of our own technologies and products that contribute to reducing environmental impact. In May 2025, we co-hosted the environmental awareness event "Race Against Climate Change Tokyo" with the Envision Racing Formula E Team. At that event, we discussed our vision for a circular economy, as well as the opportunities and challenges involved in achieving it. The event was attended by approximately 200 people, primarily customers, but also including media representatives and employees.

Teijin will always be evolving as each and every employee is aware of the "Code of Conduct". We release the videos with subtitles in local languages of all regions and countries in which the Teijin Group operates to provide employees around the world to raise them interest in the "Code of Conduct" and help their better understandings of it.
