On July 31, United Microelectronics rose 5.28% in pre-market trading, trading at $19.94/share, with turnover of $1.1156 million. The rally extends gains from the prior session as the company's blockbuster Q2 results and a fresh analyst upgrade continue to drive momentum.

United Microelectronics reported Q2 earnings per share of $0.54, crushing the consensus estimate of $0.15 by 260%, representing a 350% year-over-year increase from $0.12. Revenue came in at $2.176 billion, also surpassing the $2.06 billion estimate. CEO Jason Wang attributed the strong results to robust communication and consumer market demand, with wafer shipments rising 10.6% sequentially and capacity utilization climbing to 85%. The board simultaneously approved approximately $5 billion in capital expenditure for phased capacity expansions at its Singapore P4 facility and a new fab at its Tainan Science Park campus to capture AI and edge computing opportunities, including silicon photonics and advanced packaging development.

Additionally, Yuanta Securities upgraded United Microelectronics from Hold to Buy with a target price of NT$125, providing a dual catalyst of earnings strength and rating upgrade that continues to propel the stock higher.
