Samsung Electronics has recently made leadership changes in its memory and foundry chip divisions due to increased competition in the semiconductor market.

Jun Young-hyun has been appointed as co-CEO and will be in charge of the memory chip segment, while Han Jin-man will serve as president and head of the foundry business.

This announcement caused a 3% drop in Samsung's shares, reflecting concerns from investors about the company's ability to keep up with competitors like SK Hynix in developing advanced chips.

Samsung's stock has been declining, partly due to disappointing third-quarter profit guidance, which led Jun to issue a rare apology last month.

Analysts from Citi have noted that while Samsung is making operational changes, there have been no significant alterations to its top management structure.

However, they remain optimistic that under YH Jun's leadership, the company can navigate its current business uncertainties.
