Stakeholder Engagement

CHC recognizes having positive interaction with stakeholders as the foundation of corporate growth. Based on the definition of stakeholder in the GRI Standards Glossary, and after a discussion with each department on its specific contact objects, the Sustainability Committee has identified five categories of stakeholders including customers, suppliers, investors, employees, and general public.

Sustainability Committee reports the status of communication with CHC’s various stakeholders regularly to the Board of Directors. Status of Communication with CHC’s Various Stakeholders in 2024 had been reported to the Board of Directors on August 6, 2025. Relevant material is as follows:
