Impact on Business (GRI3-3)

CKPower recognizes that managing customer relations in an efficient, transparent, and timely manner directly influences customer satisfaction, confidence, and collaboration, which form the fundamental basis for sustaining strong commercial relationships and ensuring long-term business continuity. Effective customer relations also support revenue stability and enhance the Company’s operational risk management by reinforcing cooperative planning, execution, and joint business development.
