Samsung Revives Dual CEO Structure as TM Roh and Jun Young Hyun Take Joint Leadership Roles
Samsung is reinstating its dual CEO structure, marking one of the most significant leadership shifts at the company in recent years. According to reporting from the Korean Herald, the move has been formally approved as part of Samsung’s annual executive reshuffle and realigns the company’s leadership around its two most critical business pillars: mobile and memory.
Under the updated structure, President Roh Tae Moon, widely known as TM Roh, has been appointed the official head of the smartphone focused Device eXperience division. With this promotion, he now becomes one of Samsung’s co CEOs. Roh has informally led the division for the past eight months and is known globally as the executive responsible for the Galaxy product strategy and Samsung’s premium mobile competitiveness.
Alongside Roh, Vice Chair Jun Young Hyun, who oversees the memory driven Device Solutions division, will also serve as co CEO. His leadership has been critical in steering Samsung’s memory business through a historic surge in global demand for AI compute and next generation memory technologies. This includes managing unprecedented pressure on LPDDR5 supply, which is being squeezed by the massive expansion of HBM production for AI accelerators.
As part of the leadership adjustments, Jun Young Hyun will hand over control of the Samsung Advanced Institute of Technology to Park Hong Kun, a Harvard professor specializing in nanoscience and quantum technologies. Park will formally join Samsung on January 1 and will lead research initiatives around neuromorphic semiconductors. This class of chips imitates the parallel processing architecture of the human brain, combining storage and processing in the same location to deliver significant efficiency gains. Samsung sees neuromorphic computing as a critical domain in next generation semiconductor leadership.
Samsung is facing significant pricing pressure as we move towards the launch of the Galaxy S26 series.

Memory costs are up, Qualcomm’s AP prices have increased, and the weak Korean won is making the Qualcomm Snapdragon chip more expensive.
Samsung’s MX division is now…
Samsung’s pivot back to a dual CEO model reflects a strategic emphasis on agility and resilience at a time of intense operational headwinds. The mobile division continues to face rising costs driven by surging LPDDR5 pricing worldwide, a trend heavily influenced by AI related demand for HBM capacity. The situation is further compounded by the premium pricing of Qualcomm’s Snapdragon 8 Elite Gen 5 SoC, expected to power the upcoming Galaxy S26 Ultra exclusively.
By elevating the heads of both mobile and memory to co CEO status, Samsung is signaling a renewed internal alignment around its two largest revenue engines. The company appears poised for a more synchronized approach between its semiconductor roadmap and its flagship device strategy, especially as AI features increasingly define premium mobile hardware.
