UMC UNITED MICROELECTRONICS CORP
Price Chart
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.
