Executive Summary

UMC reported April 2026 net sales of NT$22.66 billion, up 10.80% YoY from NT$20.45 billion, and year-to-date net sales of NT$83.70 billion, up 6.88% YoY. This is a routine monthly revenue filing with solid but not exceptional growth, consistent with the prior annual report context.

Actionable Insight

Monthly revenue data alone is insufficient to change the investment thesis. Monitor the next quarterly earnings release for margin and utilization rate trends, which are the key profitability drivers for UMC.

Key Facts

  • April 2026 net sales: NT$22,663,945 thousand, +10.80% YoY
  • Year-to-date net sales: NT$83,701,847 thousand, +6.88% YoY
  • No funds lent to other parties, no endorsements or guarantees
  • Derivatives: forwards with NT$1.33B in unwritten-off contracts (fair value loss of NT$5,456 thousand) and NT$2.82B in written-off contracts (realized loss of NT$1,724 thousand)

Financial Impact

April revenue growth of 10.8% YoY is solid but within normal quarterly variability for a foundry; no guidance or earnings data provided

revenue

Risk Factors

  • Semiconductor cycle downturn could reverse revenue growth trajectory
  • Geopolitical risks related to Taiwan and China exposure
  • Derivatives losses, though immaterial at NT$5.5M fair value loss
