The Daigas Group's Identification of Materiality (Medium-Term Management Plan 2026)
Materiality Review Cycle

Material Issues (Materiality) of the Daigas Group

The Daigas Group identifies the material issues it should prioritize by considering both the impacts of its business activities on society and the environment and how medium- to long-term risks and opportunities may affect the Group’s future financial performance.
The current five material issues were identified during the formulation of the Medium-Term Management Plan 2026: “Connecting Ambitious Dreams,” which covers the three-year period from FY2024 to FY2026. In identifying these issues, the Group considered the previous Medium-Term Management Plan, progress in addressing climate change, changes in the business environment, and evolving societal expectations. The Group has established indicators and targets for each material issue to ensure close alignment with the priority strategies set out in the Medium-Term Management Plan 2026.
Progress against each indicator is reviewed annually. Initiatives related to the sustainability indicators are regularly reported and followed up on at meetings held under the Group’s sustainability management structure, and are evaluated and overseen by the Board of Directors. Through this evaluation process, the Group continually improves business initiatives related to the material issues and revises plans as necessary.

Materiality Identification Process

In formulating the Medium-Term Management Plan 2026, the Group identified its material issues by considering both its impacts on society and the environment and the potential future financial impacts on the Group. The material issues were then reviewed and approved by the Board of Directors. The Group referred to the GRI Standards and other relevant frameworks in identifying these material issues.

■ Why the Issue Is Material

Materiality	Why the Issue Is Material
Provide carbon neutral energy	• The Group engages in the energy business, which uses natural gas as its main raw material and fuel, and recognizes risks and opportunities associated with climate change. • Significant risks include the possibility that rising sea levels and natural disasters such as typhoons and torrential rains due to localized abnormal weather events, etc. may cause damage to our manufacturing and supply equipment. In addition, it is possible that our businesses may be affected by introduction of the carbon tax or significant increases in the tax rate in Japan, or an increased desire among our customers to switch to non-fossil fuels. • Meanwhile, promotion of the development and spread of renewable energy and technologies for carbon neutrality, with the aim of providing carbon neutral energy, also represents a significant opportunity for the Group. • While the Group’s energy business contributes to local job creation, investments, skills development, and economic development, we consider it essential and are working to address social and environmental issues, including the loss of biodiversity; soil, water, and air pollution; respect for human rights; and occupational safety.
Enhance the resilience of customers and society	• Stable energy supply, which allows customers to maintain and continue their lifestyles and various businesses, is a responsibility with the highest priority in the Group’s business and is regarded as the very basis of the business. • Inadequate operations and facility troubles caused by heightened geopolitical risks and natural disasters may have a large impact on markets other than the Group’s business, as well as on people’s lifestyles. • Updating facilities in a planned manner, constructing disaster-resistant infrastructure by continuing to develop pipeline networks, and promoting technological development are considered to enhance the sustainability of local communities.
Co-create advanced, diverse solutions that meet customer values	• For the sustainable growth of the Group’s business, we consider it essential to co-create advanced, diverse solutions that meet diversifying customer values and can solve global social issues. • In order to increase our market competitiveness, we consider it necessary to pursue added value with DX and invest in the creation of businesses in new domains. • We also consider it important and therefore work to strengthen the organizational culture and structure that encourage employees to reengineer business processes and change behavior.
Create an environment that enhances value for employees and the company	• In a rapidly changing business environment where the working population is decreasing, the labor market is becoming more flexible, and people have diversifying ways of work, the Group is driving forward business portfolio management, envisioning a strategy to keep growing by diversifying its business. • To achieve sustainable growth in the future as well, we recognize the need to further enhance initiatives for human capital. We consider it necessary to acquire and develop diverse talent with high levels of expertise; deploy talent strategically to align with job requirements, deploying employees to serve the purpose of business operations while achieving higher levels of employee satisfaction; create an environment where employees feel more rewarded and motivated. In addition, we consider it necessary to realize maximization of the overall output.
Maintain and improve the soundness and flexibility of management foundation	• Even in an environment where the future is increasingly uncertain and difficult to foresee, we recognize that continuing to meet the trust and expectations from the Group’s stakeholders and steadily addressing key issues will lead to the development of supply chains and local communities as a whole. • We consider that a sound and sustainable management foundation will be maintained and upgraded by not only ensuring legal compliance but also respecting human rights, including the safety, health, and employment and working environment of stakeholders involved in the Group’s business, and working on the enhancement of the corporate governance system. • To implement the Group’s business strategy steadily, reengineer business processes, and further grow in fields other than energy, we consider it necessary to secure core DX staff who drive relevant initiatives.

Comment by Outside Expert The Daigas Group's Identification of Materiality (Medium-Term Management Plan 2026)

Management
While the process for identifying materiality has not changed significantly from FY2021.3, when the previous Medium-Term Management Plan was formulated, relevance to corporate strategies is clearer this time. This can be attributable to the fact that materiality was identified with consideration given to medium- to long-term targets, including the Carbon Neutral Vision announced in January 2021 to achieve carbon neutrality by 2050. As with the last time, the Daigas Group adopted the idea of so-called double materiality, where both financial impacts and social and environmental impacts are taken into account. This approach can be considered appropriate as the Group engages in infrastructure-related businesses that have considerable social and environmental impacts. The identified materiality has a limited number of elements, indicates overall directions, and is clearly aligned with “Key Strategy: the Three Commitments” in the Medium-Term Management Plan 2026. When it comes to KPIs that are linked with materiality, financial indicators are increasingly integrated with sustainability indicators with an eye on 2026, the target fiscal year of the Medium-Term Management Plan. Meanwhile, part of the targets are qualitative. Going forward, I expect the Group to improve accountability for such targets and fine-tune them.
