Outside Director Resignation: Han Chan-sik Steps Down for Personal Reasons — HD Hyundai Electric

Summary

Outside director Han Chan-sik voluntarily resigned on June 21, 2026, citing personal reasons. He was originally appointed in March 2023 and most recently reappointed in March 2026 for a three-year term. Following his departure, the board shrinks from 5 to 4 registered directors, and outside directors drop from 3 to 2, reducing the outside director ratio from 60% to 50%. As a large-scale corporation, the company is required to maintain a majority of outside directors, so the 50% ratio brings governance compliance into a narrower margin pending a replacement.
