The 27% YoY September revenue growth is a strong beat vs the prior year's run rate, likely driven by foundry demand recovery. The NT$6.98B equipment purchase from Applied Materials signals capacity expansion confidence. Monitor upcoming Q3 2026 earnings for margin impact of this capex cycle and any guidance revision.
Price Chart
Executive Summary
UMC reported September 2026 net sales of NT$25.35 billion, up 27.22% YoY from NT$19.93 billion, and YTD net sales of NT$204.01 billion, up 16.08% YoY. The company also disclosed a NT$6.98 billion machinery and equipment purchase from Applied Materials South East Asia for production and R&D. The strong monthly revenue growth is a positive operational signal, but the capex commitment signals ongoing investment spending.
Key Facts

- Year-to-date net sales: NT$204,009,681 thousand, +16.08% YoY vs NT$175,743,654 thousand
- Machinery and equipment acquisition from Applied Materials South East Asia Pte. Ltd. for NT$6,983,784,720 (non-related party)
- Equipment purchase spans Dec 23, 2025 to Oct 1, 2026, for production and R&D use
- No funds lent to other parties, no endorsements/guarantees outstanding

Financial Impact
September revenue grew +27.22% YoY, adding NT$5.42 billion in absolute terms; YTD revenue up +16.08% YoY, adding NT$28.27 billion. Equipment capex of NT$6.98 billion (~$210M USD at current rates) is a material but manageable investment.
Risk Factors
- Equipment capex of NT$6.98B may pressure near-term free cash flow and depreciation charges
- Derivatives show a realized loss of NT$26.9M on written-off forwards, indicating some FX hedging costs
- Semiconductor cycle demand could soften; single-month revenue beat does not guarantee sustained momentum
