Declaration of Ethics and Compliance Management Practices Dear HD Hyundai Electric employees, Last year, we tried to achieve sustainable growth amid the uncertainty of the global economy and the rapidly changing regulatory environment, and reorganized the regulations and systems related to the operation of the Fair Trade Compliance Program (CP) to establish a fair and clean culture throughout our business activities. Recent changes, however, such as increased surveillance of collusion and unfair subcontracting practices, EU-focused ESG disclosure and stricter due diligence related regulation, have been demanding a higher level of transparency and ethical responsibility for businesses. In line with these changes, all our decisions must be in accordance with laws and principles, and there must be moral justification. All members of the company must adhere to the principles in their respective positions and act in a transparent and fair manner to strengthen its competitiveness. Therefore, we need to practice ethics and compliance management more systematically and inspect and strengthen our internal control and management systems. Ethics and compliance are not just slogans but are the core management philosophy of our company and the basic principles that all executives and employees must practice. Our sustainable growth can only be achieved when all members keep this in mind, act responsibly and follow the principles in all tasks and judgments. We ask that you understand the value of ethics and compliance management and join us in practicing it. As we welcome the new year, we once again ask for your active practice and cooperation for ethics and compliance management so that we can overcome the uncertain business environment and become HD Hyundai Electric that is loved and trusted by everyone.
