United Microelectronics Corporation (UMC) reported unaudited net sales for May 2025, totaling NT$19,480,057 thousand. This figure represents a slight decrease of 0.15% compared to May 2024.

For the cumulative period from January to May 2025, UMC's consolidated revenues reached NT$97,793,544 thousand. This still reflects a 4.17% year-over-year growth.

The marginal year-over-year decline in May sales, while the year-to-date figure remains positive, indicates some softening in demand for UMC's semiconductor manufacturing services for the month.
