True
SK Inc. has appointed Kim Sun-hyuk to the position of damdang-sajang (담당사장), an executive-level post within the SK Group holding company, resolving the claim that the company had made such a promotion.
Kim Sun-hyuk's elevation to the executive director-level post at SK Inc. has been confirmed as fact, based on a review of 12 primary sources. The appointment places Kim within the senior management structure of SK's holding company, which oversees the group's portfolio spanning semiconductors, energy, and telecommunications through affiliates including SK hynix.
SK Inc. serves as the holding company of SK Group, whose semiconductor flagship SK hynix is a leading supplier of high-bandwidth memory (HBM) for AI applications. Executive appointments at the holding company are closely watched as signals of leadership direction across the group's businesses.
The claim that SK Inc. had named Kim Sun-hyuk to the damdang-sajang post corresponds with the available evidence, and it is therefore true.
