Performance Analysis
UMC delivered a quarter marked by stable top-line growth and improved utilization, with consolidated revenue rising slightly on stronger wafer shipments and a 78% utilization rate, even as FX dampened results by 3%. Gross margin reached 29.8%, benefitting from higher volume and a firm average selling price (ASP), while net income approached NT$15 billion. The business mix shifted notably: North America grew to 25% of revenue (up 5 points QoQ), while Asia declined, reflecting both customer restocking and market share gains in strategic regions.
Technology mix was another standout, as 22nm and 28nm nodes together contributed 35% of revenue, with 22nm alone now above 10%. UMC’s 12X Shaman Fab added incremental 12-inch capacity, and annual output is tracking to the 1.8 million wafer target, with 90% of capacity in 12- and 8-inch platforms. Segment trends showed communications and computers rising as consumer demand softened, and the company’s ASP remained resilient despite cost and FX headwinds.
- Node Mix Shift: 22nm and 28nm nodes now drive over a third of sales, supporting margin stability and future growth.
- Regional Revenue Rotation: North America’s revenue share increased, signaling traction with restocking and new customer wins.
- Cost Controls vs. Inflation: Manufacturing cost discipline offset higher labor and electricity, but bonus accruals rose with profit.
UMC’s financial position remains solid, with cash above NT$100 billion and equity at NT$361 billion, supporting continued capital investment and flexibility amid macro and geopolitical uncertainty.
Executive Commentary
"Our 22nm technology platform continues to provide us with a differentiation in the market. With 22nm revenue now accounting for more than 10% of total sales, in 2025 alone, we are projecting over 50 product tables, and we expect 22 nanometer contribution will continue to increase in 2026."
Jason Wang, President
"Gross margin also primarily depends on utilization rate, ASP, product mix, depreciation, and foreign exchange. Even though the foreign exchange rate may be on a forecast basis better than forecast, I still appreciate against U.S. dollars our key priority receivable currency. So still in an unfavorable situation, as I mentioned earlier, that almost beat up about 3% of our total revenue."

Strategic Positioning
1. Specialty Technology Leadership
UMC’s differentiated specialty nodes, particularly 22nm and 28nm, are now the company’s main growth engines, with 22nm contributing over 10% of sales and projected for double-digit growth in 2026. The company’s 35nm BCD (Bipolar-CMOS-DMOS, a power-efficient mixed-signal technology) platform is being positioned for automotive and industrial markets, broadening its specialty portfolio and defensibility.
2. Geographic Diversification and Tariff Hedging
UMC’s multi-region manufacturing footprint is a deliberate response to rising tariff and supply chain risks. The Singapore and US capacity expansions will enable a more balanced split between Taiwan and overseas sites, directly addressing customer and regulatory demand for supply chain resilience. The US partnership, especially the 12nm node with Intel, is both a hedge and a springboard for future advanced node and packaging opportunities.
3. Advanced Packaging and AI Market Readiness
UMC is investing in advanced packaging capabilities, including 2.5D interposer with deep trench capacitor (DTC) and wafer-to-wafer stacking. While current capacity is not expanding, these technologies are positioned for future AI, HPC (high-performance computing), and edge applications, with meaningful revenue expected from late 2026 or 2027 as customer adoption ramps.
4. Cost Competitiveness and Smart Manufacturing
Cost discipline remains central, with UMC leveraging both supplier negotiations and internal process improvements, such as smart manufacturing and AI-driven fab optimization, to offset inflation in labor and utilities. Depreciation costs are peaking, providing a potential margin floor in future periods.
5. Customer Engagement and Pricing Strategy
UMC’s pricing approach is anchored in technology value and long-term agreements (LTAs), balancing customer share gains with capex returns. Management signaled ASP stability through Q4 and is negotiating 2026 pricing, aiming to avoid material concessions despite ongoing LTA expirations and industry pricing pressures.
Key Considerations
This quarter reinforced UMC’s focus on differentiated technology, geographic risk mitigation, and operational rigor. Investors should weigh the following:
- Specialty Node Growth Trajectory: Double-digit 22nm and 28nm growth is expected to underpin shipment and margin gains in 2026.
- Tariff and Supply Chain Exposure: US and Singapore capacity investments are both a risk hedge and a source of new customer opportunity.
- Advanced Packaging Optionality: AI and edge market adoption of UMC’s packaging technology could create new revenue streams, but timing remains uncertain.
- Margin Levers and Cost Pressures: Depreciation is peaking, but labor and energy inflation continue; smart manufacturing is a key offset.
- Customer Mix and Regional Shifts: North American customer wins and restocking are shifting the revenue base, with Asia share declining.
Risks
UMC faces several material risks: Tariff policy changes or new US-China trade barriers could disrupt demand or force further supply chain realignment. Customer pricing pressure remains a concern, especially as LTAs expire and competitors adjust capacity. Cost inflation, particularly in labor and utilities, may erode margins if not offset by technology mix or operational gains. Finally, the ramp in advanced packaging and US partnership execution carries both timing and market adoption uncertainty.
