United Microelectronics Reports Q4 Earnings with Mixed Results
United Microelectronics Corp (UMC) saw its stock price drop by 8.74% as it crossed below the 5-day SMA, reflecting a challenging market environment.
In its Q4 2025 earnings report, UMC reported a revenue increase of 2.4% year-over-year to NT$61.81 billion, exceeding expectations, but its earnings per share of $0.129 fell short of analyst estimates, indicating profitability pressures. The company also announced significant capital expenditures of $501 million for Q4, totaling $1.6 billion for the year, while maintaining an optimistic outlook for 2026 driven by advanced packaging and silicon photonics.
Despite the mixed results, UMC's revenue growth demonstrates resilience in a tough demand environment, and its strategic investments may position the company for future growth in the semiconductor market.
