United Microelectronics Corporation reported stronger third-quarter operations on October 28, with record wafer shipments and higher factory utilization. The results were carried by wallstreetONLINE from the company announcement.

Since the previous report on November 2, the Lang and Schwarz quote has fallen 2.95 percent from 15.25 euros to 14.80 euros. The real-time quote of United Microelectronics Corporation stock showed 14.80 euros at 16:45 CET on Tuesday, November 3, 2026.

Operations strengthen into the fourth quarter

Revenue increased 8.0 percent from the second quarter and 25.6 percent from a year earlier to NT$74.24 billion. Gross margin reached 34.0 percent, up from 32.5 percent in the second quarter and 29.8 percent a year earlier. Operating income rose 24.7 percent sequentially to NT$18.64 billion.

Wafer shipments increased 7.3 percent sequentially to 1.212 million 12-inch-equivalent wafers, a quarterly record. Overall capacity utilization reached 92 percent, compared with 85 percent in the second quarter and 78 percent in the year-earlier period. Revenue from 22nm processes represented a record 18.3 percent of wafer sales.

Expansion raises execution demands

For the fourth quarter, management expects wafer shipments to increase by a low-single-digit percentage, firm US-dollar average selling prices, a gross margin comparable with the third quarter and utilization in the low-90 percent range. Quarterly capacity is expected to rise from 1.325 million to 1.337 million 12-inch-equivalent wafers.

UMC's board approved an additional capital-expenditure budget of approximately US$3.2 billion on October 28. The spending is intended to accelerate expansion in Singapore and Tainan, while the 2026 cash-based capital-expenditure budget remains US$2.0 billion. For investors, the next test is whether stronger demand and utilization can offset the financial and execution demands of the expansion.
