On July 22, United Microelectronics rose 3.49% overnight, trading at $21.85/share, with turnover of $304,700.

On the news front, the semiconductor sector's recovery trend continued, with improving industry sentiment driving UMC to extend its rebound from a prolonged selloff that had seen cumulative declines exceeding 18% over multiple consecutive trading sessions. Earlier in the week, sector peers including SK Hynix, Micron Technology, Intel, and AMD all posted notable gains, reflecting broad-based sentiment repair across the chip industry.

On the fundamental side, UMC reported Q2 revenue growth of nearly 17% year-over-year, marking a 15-quarter high. The company's Singapore wafer fab has successfully commenced mass production of its first batch of silicon photonics wafers, supporting 1.6Tbps high-bandwidth interconnect solutions for next-generation AI infrastructure. The next earnings report is scheduled for July 29, with consensus EPS expected at $0.15.
