On May 26, UMC rose 10.15% in pre-market trading, trading at $20.52/share, with trading volume of $178,800. The sharp move higher was driven by a combination of strong Q1 earnings, confirmed wafer price hikes, and the launch of a new technology platform.

On the earnings front, UMC reported Q1 net profit of NT$16.17 billion, surging 108% year-over-year and significantly exceeding market expectations. Gross margin reached 29.2% while capacity utilization improved to 79%. The company's pricing momentum remains robust, with Q1 average selling prices rising 8% year-over-year. Management guided for an additional 5%-7% ASP increase in Q2, which is expected to push gross margins above 30%.

Additionally, UMC recently launched its 14nm eHV FinFET platform targeting next-generation OLED display driver ICs for smartphones. The new platform delivers 40% lower power consumption and 35% chip area savings, reinforcing the company's competitive positioning in mature-node foundry services. The confluence of beat-and-raise fundamentals, structural pricing tailwinds in mature process nodes, and technology advancement has sustained upward momentum in the stock over recent sessions.
