KT says outside director Yoon won't seek reappointment amid governance realignment

KT Corp. said on March 16 that outside director Yoon Jong-su, who also serves as an environmental adviser to the law firm Kim & Chang, has decided not to seek reappointment. Yoon has been the chair of KT’s board and the ESG committee, guiding the company’s environmental, social and governance initiatives.

KT’s Outside Director Candidate Recommendation Committee had identified Yoon as the sole reappointment candidate among four external directors at its February 9 meeting. The company had planned to include Yoon in the slate at the ordinary general shareholders meeting on March 31, alongside a slate that also included CEO candidate Park Yun-Young and other external directors.

The other external director candidates listed for consideration at the meeting are Kim Young-han, a professor of electronic information engineering at Soongsil University; Kwon Myung-sook, CEO of Intel Korea; and Seo Jin-seok, former CEO of EY Korea. If approved, they would join the board as outside directors.

Yoon has served as KT’s board chair and ESG committee chair for about two and a half years, contributing to the strengthening of KT’s ESG governance framework. He is recognized as a climate, energy and environmental expert, and KT has been noted for improving its sustainability management under his leadership, with top ratings from ESG evaluation agencies.

Industry observers say the voluntary decision appears to align with broader leadership changes at KT, as the company ushers in a new management team. Some interpret the move as potentially connected to ongoing governance realignment as a new CEO and board take shape.

If the slate is not filled before the shareholders’ meeting, KT could leave the external director seat vacant temporarily, delaying the formation of a full new board. Yoon’s parting message in his statement emphasized collaboration: “I hope the new CEO and the board will work together to achieve KT’s remarkable development.”

Why this matters to U.S. readers: KT is a major Korean telecom and digital services provider with links to global technology supply chains and potential partnerships with U.S. firms. Changes in KT’s governance and ESG leadership can influence investor confidence, cross-border collaboration, and the company’s approach to risk management and sustainability reporting. The slate of external directors under discussion includes executives from Intel Korea and senior figures connected to the audit and advisory sector, underscoring how Korean corporate governance shifts can affect foreign partners, technology ecosystems, and market access for U.S. companies relying on Korean infrastructure and innovation.
