1. Material Topic Analysis

1. Material Topic Identification Process
HDRE communicates with stakeholders through diverse channels and integrates stakeholder feedback into its materiality analysis to identify the issues most important to both stakeholders and the Company. In 2025, HDRE conducted surveys across internal operating units and eight categories of external stakeholders. A total of 117 valid questionnaires were collected, and 20 ESG topics were assessed across environmental, social, and economic/governance dimensions.
Based on the assessment results, HDRE established a significance threshold at the 75th percentile for internal impact scores or external stakeholder concern. Ten material topics were identified and reviewed and approved by the Sustainable Development Office. For each material topic, HDRE discloses impacts, boundaries, response strategies, management approaches, performance results, and short-, medium-, and long-term objectives.

STEP 1 Stakeholder Identification

In accordance with the five principles of the AA1000 Stakeholder Engagement Standard (AA1000 SES), HDRE identifies internal and external groups or individuals who significantly influence, or are influenced by, the Company.

  • Eight key stakeholder groups were identified: employees, customers, government agencies, shareholders and investors, suppliers and contractors, media, communities, and NGOs/research institutions.
STEP 2 Sustainability Topic Identification

Drawing on sustainability standards and frameworks (GRI, TCFD, SASB), issues of concern among domestic and international industry peers, industry and global sustainability trends, and stakeholder engagement, HDRE identified sustainability topics relevant to its business operations.

  • A total of 20 sustainability topics were selected for impact assessment in 2025.
STEP 3 Impact Assessment

HDRE assessed each topic based on actual and potential impacts identified internally and the level of concern expressed by external stakeholders. A significance threshold at the 75th percentile was applied to support the prioritization of material topics.

  • Thirty-two supervisors and key representatives participated in the internal survey and alignment workshop; 117 valid questionnaires were collected in total.
STEP 4 Determination of Material Topics

Through internal and external surveys and discussions between the Sustainable Development Office and relevant departments, HDRE evaluated the relevance and impact of each topic on business operations.

  • Ten material topics were identified and approved by the Sustainable Development Office.
STEP 5 Develop Management Policies and Conduct Regular Reviews

HDRE reviews the materiality assessment results against the previous year and establishes management policies and objectives for each material topic. Annual reviews are conducted to ensure alignment with sustainability and integrity requirements.

  • For each material topic, HDRE establishes response strategies, performance indicators, and short-, medium-, and long-term objectives.

2. Sources of Sustainability Issues
HDRE identifies sustainability topics through sustainability standards and frameworks, issues of concern among domestic and international industry peers, industry and global sustainability trends, stakeholder engagement, and internal operational review. With a focus on issues relevant to HDRE’s business operations, 20 sustainability topics were selected for impact assessment in 2025.

Sustainability Standards and Frameworks

Referenced the GRI Standards, Task Force on Climate-related Financial Disclosures (TCFD), and Sustainability Accounting Standards Board (SASB), together with other applicable sustainability frameworks.

Domestic and International Industry Peers

Reviewed sustainability issues emphasized by domestic and international industry peers to identify topics relevant to HDRE’s operations.

Industry and Global Sustainability Trends

Considered key industry developments and broader global sustainability trends that may affect HDRE’s business and stakeholders.

Stakeholder Engagement

Integrated feedback and expectations gathered through ongoing engagement with HDRE’s eight key stakeholder groups.

Business Operations and Internal Review

3.  Sustainability Topics
In 2025, HDRE identified 20 sustainability topics through sustainability standards and frameworks, peer issues, industry and global sustainability trends, and stakeholder engagement. The topics were categorized into governance, environmental, social, and cross-dimensional E/S/G areas for impact assessment.

2. Material Topic Impact Analysis

HDRE evaluated 20 sustainability topics based on actual and potential positive and negative impacts, together with the level of concern expressed by stakeholders. A significance threshold at the 75th percentile (PR75) was applied to determine materiality. The 2025 assessment identified ten material topics.

Compared with 2024, Waste Management, Economic Performance, and Risk Management were added as material topics, while Occupational Safety and Health was renamed Occupational Health and Safety. Greenhouse Gas Management, Product Quality and Responsibility, and Innovation R&D and Management were no longer listed as standalone material topics because they have been integrated into routine environmental management, established quality management mechanisms, and broader economic performance and risk management processes, respectively.
