On January 7th, United Microelectronics Corporation (UMC.US) disclosed its consolidated revenue figures for December 2025: the monthly consolidated revenue reached NT$19.28 billion, representing a 9.2% decrease compared to November, yet it grew by 1.66% year-over-year relative to December 2024. For the fourth quarter, the consolidated revenue totaled NT$61.8 billion, marking a sequential increase of 4.5% and surpassing market expectations. For the full year of 2025, the cumulative revenue amounted to NT$237.553 billion, a 2.26% increase year-over-year, achieving the second-highest annual revenue in the company's history, second only to the NT$278.705 billion recorded in 2022. During the prior earnings call, United Microelectronics projected that for the fourth quarter of 2025, wafer shipments would remain flat compared to the third quarter, the average selling price (ASP) in US dollars would stay stable, and the gross margin was anticipated to reach 28.92%. However, capacity utilization was expected to experience a slight decline, falling to a range of 74% to 76%, and the gross margin was also forecast to dip slightly, settling within a range of 27% to 29%. Concurrently, the capital expenditure for 2025 was planned to be maintained at $1.8 billion. Additionally, the company projected that the full-year 2025 shipment volume would achieve growth in the low double digits (low-teens percentage range). During the earnings call, UMC's Chief Financial Officer, Liu Qidong, pointed out that although the foreign exchange forecast might be more favorable than previously anticipated, the US dollar still exhibited an appreciating trend. Given that the US dollar is the primary currency for UMC's accounts receivable, and considering that current exchange rates, depreciation, and other factors collectively create an unfavorable environment, these elements were expected to impact revenue by approximately 3%. Jason Wang, Co-President of United Microelectronics, stated that UMC's US dollar average selling price (ASP) has been very stable and consistently maintained at a healthy level. At the time of writing, United Microelectronics' stock was up nearly 9% in pre-market trading, reaching $8.83.
