Stakeholder

Communication Channels

LemTech values communication and interaction with stakeholders, recognizing them as indispensable partners for sustainable business operations. Guided by the Global Reporting Initiative (GRI) Standards and the AA1000 Stakeholder Engagement Standard (AA1000 SES), we have established a stakeholder engagement policy. Through institutionalized mechanisms, we identify key stakeholders and develop diversified communication channels to understand their concerns, respond to expectations, and incorporate their feedback into materiality analysis and sustainability management strategies.

Stakeholder identification framework

We employ AA1000 SES’s five dimensions – Accountability, Influence, Urgency, Diverse Perspectives, and Dependency – as the basis for stakeholder identification. This framework identifies primary stakeholder categories including: employees, shareholders and investors, clients, suppliers, and non-profit organizations/communities. These categories are reviewed and updated annually by the Sustainability Committee to reflect evolving operational contexts and external priorities.

Objectives of engagement

The core objectives of stakeholder engagement include: gaining in-depth understanding of expectations regarding the Company’s operations, governance, products, and sustainability issues; utilizing insights to identify material topics and adjust sustainability strategies; strengthening trust relationships and corporate transparency; and proactively identifying risks and collaboration opportunities.

Engagement methods

Tailored to different stakeholder attributes and interaction needs, we implement diversified engagement methods including: employee interviews and communication meetings, annual supplier interviews and audits, client feedback mechanisms, regulatory and industry association participation, and industry-academia collaborations. Simultaneously, during material topic assessment, sustainability report compilation, and policy formulation stages, we proactively collect and integrate stakeholder input to ensure the engagement process demonstrates substantive participation, responsiveness, and representativeness.

The Company’s stakeholder engagement activities are disclosed in the 2025 Sustainability Report, which was approved by the Board of Directors on August 21, 2026.
