Agenda 1. Election of a Standing Director as Comptroller & Auditor General and Member of the Audit Committee

The nominee, Mr. Kim, Tae-Ok has possessed outstanding professional expertise across all sectors of the electric power industry by serving at Korea Electric Power Corporation for approximately 35 years and performing various roles, including Corporate Senior Executive Vice President & Chief Power Grid Officer, Vice President of Regional Headquarters KEPCO Gwangju-Jeonnam and Vice President & Head of Technology Planning Department.

In particular, through his position as the Corporate Senior Executive Vice President & Chief Power Grid Officer, a standing director, he has not only cultivated a wealth of knowledge in the planning, construction, and operation of the national power grid—a key pending issue of KEPCO—but also internalized experiences in various business fields such as the Vice President & Head of Technology Planning Department. Through these, he has equipped himself with auditing capabilities to identify and manage structural risks occurring at the boundaries between departments and overall business processes of the organization.

If the nominee is elected as a Standing Director as Comptroller & Auditor General and Member of the Audit Committee, he is expected to preemptively manage and resolve the structural risks of the company based on his in-depth understanding of KEPCO, and contribute to creating an advanced audit culture that supports and encourages employees to actively perform their duties.
