On July 13, United Microelectronics fell 3.12% in pre-market trading, trading at $23.63/share, with turnover of $115,300. The decline came as the broader semiconductor sector faced systemic selling pressure, erasing earlier gains.

On the news front, the semiconductor sector saw widespread weakness, with Micron Technology down 6.17%, Advanced Micro Devices down 3.15%, Intel down 2.86%, NVIDIA down 2.02%, and Broadcom down 1.57%. United Microelectronics had earlier risen as much as 4.2% in pre-market trading on news of ASML achieving a breakthrough in EUV light source technology, but the sector-wide downturn caused those gains to fully reverse.

On the fundamental side, United Microelectronics reported Q2 revenue growth of nearly 17% year-over-year, marking a 15-quarter high. June consolidated revenue reached NT$23.1 billion, up 23% annually, while first-half cumulative revenue rose 11.28% to NT$129.8 billion. The company is scheduled to report its next earnings on July 29.
