1. On October 15, South Korean media reported that Samsung is considering introducing GlobalFoundries as a second foundry partner for the Galaxy smartphone display driver chips; if the evaluation is finalized, UMC’s exclusive supplier position for Samsung’s related chips may be broken. On October 19, related news was reported again, but current information does not show that Samsung has made a final decision.

2. According to available data, UMC has accumulated a 144.30% increase this year, but has fallen 11.90% over the past five days, indicating that its stock price is currently in a pullback phase; the significant year-to-date growth may increase short-term profit-taking pressure.
