United Microelectronics Corporation stock (ISIN US9108734057) was trading at EUR 18.75 at Lang & Schwarz on October 16, 2026 at 10:00 a.m. CEST. The company is expanding its Singapore manufacturing base toward annual output of 1.3 million wafers, according to Singapore Economic Development Board on September 2, 2026.

Singapore capacity reaches 1.3 million wafers

The expansion gives UMC a larger position in silicon photonics and co-packaged optics, technologies used to move data inside artificial intelligence data centers. The Singapore plant began commercial production earlier in 2026 and is planned to become UMC's largest production base outside Taiwan, with annual output reaching 1.3 million wafers in the next few years, Singapore Economic Development Board reported.

The investment is part of a broader capacity program. UMC raised its 2026 capital expenditure budget to USD 2.0 billion from USD 1.5 billion, while its new Singapore facility covers 111,800 square meters, according to the same report.

What does the expansion mean for results?

UMC's second-quarter 2026 revenue rose 12.6 percent sequentially to TWD 68.7 billion, while 22-nanometer revenue reached 17.5 percent of sales, Zacks reported on September 29, 2026. The company also expects its artificial intelligence-related business to exceed USD 1.0 billion over the next three years, the report said.

Three dated developments shape the story

On September 2, 2026, Singapore Economic Development Board described UMC's plan to reach 1.3 million annual wafers. On October 7, 2026, a UMC filing said media projections of 21 percent revenue growth and 133 percent profit growth for 2026 were speculative. On October 13, 2026, UMC scheduled its third-quarter 2026 online investor conference for October 28, 2026, according to StockTitan.

Dates investors can mark

The next substantiated company date is October 28, 2026, when UMC is scheduled to present its third-quarter financial and operating results in an online investor conference, according to StockTitan.

Stock price and next catalyst

For investors, the capacity expansion and the October results date provide two concrete checkpoints for judging whether stronger specialty-chip demand is translating into operating performance.
