Samsung Electronics CEO Kwon Oh-hyun unexpectedly announced his plans to step down earlier this month, citing the need for new leadership amid “unprecedented crisis,” and the company has now announced his replacements. There’ll be three leaders each with a specific area of focus — Kim Ki-nam heading up the components business, Kim Hyun-suk (HS Kim) running consumer electronics, and Koh Dong-jin (DJ Koh) in charge of mobile and IT.

Yoon Boo-keun (BK Yoon) and Shin Jong-kyun (JK Shin) are resigning altogether from their previous co-CEO roles after stepping back from direct control in 2015. It’s not clear whether any one of the new leaders will have an elevated status similar to Kwon’s — Samsung’s announcement describes the new arrangement as “maintaining the current three co-CEO management structure.”
