On May 27, United Microelectronics (UMC) rose 5.74% overnight, trading at $22.44/share, with trading volume of $377,600.

On the news front, multiple catalysts continued to drive the stock higher. The company previously reported Q1 net profit surging 108% YoY to NT$16.17 billion, significantly beating market expectations, with gross margin reaching 29.2% and capacity utilization rising to 79%. Mature-node wafer pricing trends remain strong, with Q1 average selling prices up 8% YoY and Q2 expected to increase another 5-7%, potentially pushing gross margins above 30%.

Additionally, Taiwan Exchange filings disclosed that UMC acquired approximately NT$1.03 billion worth of machinery and equipment from Tokyo Electron between May 2025 and May 2026 for production purposes. Industry analysts view this non-related-party acquisition as evidence of ongoing capacity expansion at UMC's fabs, potentially enhancing future output and competitiveness in the foundry market. The company also recently launched its 14nm eHV FinFET platform, delivering 40% power reduction and 35% chip area savings, further strengthening its technological positioning.
