United Microelectronics Corporation (UMC) closed out 2025 with a steady fourth-quarter performance, posting a moderate lift in revenue as currency tailwinds and solid demand for its 22/28nm chips helped support results.
For the fourth quarter of 2025, UMC said consolidated revenue rose to NT$61.81 billion. The company attributed the improvement largely to favorable foreign exchange conditions, alongside continued growth in its 22/28nm semiconductor business—an important “sweet spot” of mature-node manufacturing that remains widely used across everything from consumer electronics to industrial applications.
While cutting-edge chipmaking often grabs the spotlight, UMC’s update highlights why mature process technologies still matter: they tend to deliver reliable demand, long product lifecycles, and broad customer adoption. The company’s 22/28nm segment in particular continues to be a key contributor, reflecting ongoing customer needs for cost-effective performance and stable supply.
UMC also outlined its investment posture for the year ahead, setting its 2026 capital expenditure plan at US$1.5 billion. The capex figure signals a measured approach—large enough to maintain competitiveness and support priority areas, while remaining disciplined amid a changing global semiconductor landscape.
This combination of a revenue uptick in late 2025 and a clearly defined 2026 capex plan underscores UMC’s focus on sustaining momentum in core technologies, managing costs carefully, and positioning its manufacturing business for continued demand in established nodes.
