联电股价异动上涨4.34%，半导体行业景气度提振成主因

Core Viewpoint - UMC's stock price experienced a significant increase of 4.34% on February 11, 2026, closing at $10.34, driven by multiple factors including industry sentiment, resilient fundamentals, strengthened long-term growth expectations, and valuation recovery [1] Industry Sector Situation - Since February 2026, the semiconductor industry has seen a new wave of price increases across various segments, with companies issuing price hike notices, indicating improved supply-demand dynamics. On February 11, the semiconductor sector in the U.S. rose by 2.27%, outperforming the broader market as the Nasdaq index fell by 0.05%, positively influencing UMC [2] Company Fundamentals - Despite a quarter-on-quarter decline in net profit for Q4 2025, UMC reported revenues of NT$61.81 billion (approximately $1.97 billion), exceeding market expectations, with a gross margin increase to 30.7%. Revenue from the 22nm process surged by 31% quarter-on-quarter, accounting for over 13% of total revenue, becoming a core growth driver [3] Future Development - Institutional reports suggest that UMC is expected to benefit from the transfer of mature process orders from TSMC, potentially leading to a 19% revenue increase. Additionally, the new Fab12i P3 facility in Singapore is set to ramp up production significantly in the second half of 2026, adding 30,000 wafers per month of high-margin capacity. The company's focus on silicon photonics and advanced packaging technologies is also viewed as a medium to long-term growth opportunity [4] Financial and Technical Aspects - As of February 11, UMC has seen a year-to-date increase of 31.49%, with a recent turnover rate of 0.23% and a trading volume of approximately $58.18 million, indicating a recovery in activity. The price-to-earnings ratio (TTM) stands at 18.63, suggesting that some investors perceive a match between valuation and growth expectations, particularly with a projected over 20% increase in 22nm revenue for 2026 [5] Recent Company Status - It is important to note that the company guidance indicates a potential decline in capacity utilization to the mid-70% range for Q1 2026, with gross margins possibly dropping to the high 20% range. If industry demand recovery falls short of expectations or the transfer of TSMC orders slows, it may impact short-term performance [6]
