United Microelectronics Corporation (ISIN US9108734057) reported second-quarter revenue of TWD 68.73 billion, up 17.00 percent from a year earlier, while gross margin reached 32.50 percent. Drillr published those figures on October 20, 2026. UMC stock was priced at EUR 16.80 at Lang & Schwarz on October 23, 2026 at 4:32 p.m. CEST.

Revenue recovery meets margin test

The second-quarter revenue figure marked a 17.00 percent year-over-year increase and a 12.60 percent rise from the prior quarter. Capacity utilization reached 85.00 percent, up from 79.00 percent in the first quarter, giving the foundry stronger fixed-cost absorption.

The operating picture was more mixed. Operating margin stood at 21.80 percent in the second quarter, while net income attributable to the parent reached TWD 42.26 billion. The large gap between operating income and net income reflected substantial non-operating income, making gross margin and core operating profit important measures for the next report.

Valuation stays below larger peers

UMC traded at a P/E ratio of 18.87 and had a market capitalization of USD 47.2 billion as of October 23, 2026. Taiwan Semiconductor Manufacturing Company carried a P/E ratio of 24.27 and a market capitalization of USD 2.2 trillion, while Semiconductor Manufacturing International Corporation had a P/E ratio of 124.27 and a market capitalization of HKD 476.2 billion on the same date.

UMC's lower multiple reflects its mature-node focus and smaller scale. The company operates a pure-play foundry business, producing wafers for chip designers rather than selling branded chips. Citi identified UMC as a Taiwan-based company with NYSE-listed ADSs and the 5:1 ordinary-share-to-ADS ratio on October 21, 2026.

Comparison with peers

UMC: P/E 18.87, market capitalization USD 47.2 billion.

Taiwan Semiconductor Manufacturing Company (NYSE, USD): P/E 24.27, market capitalization USD 2.2 trillion.

Semiconductor Manufacturing International Corporation (HKEX, HKD): P/E 124.27, market capitalization HKD 476.2 billion.

What the margin figure means

For investors, the key comparison is between rising utilization and the cost of new capacity. UMC's 32.50 percent gross margin in the second quarter was higher than the 28.70 percent reported a year earlier, but depreciation can limit the benefit if capacity expands faster than demand.

Stock price and operating scale

UMC's NYSE quote was USD 18.94 at 10:41 a.m. ET on October 23, 2026, while the Lang & Schwarz euro quote was EUR 16.80 at 4:32 p.m. CEST. The two quotations are shown separately because they represent different trading venues and currencies.

UMC's next market test is whether stronger utilization translates into further margin expansion rather than being absorbed by depreciation. The second-quarter figures provide a clear baseline: TWD 68.73 billion in revenue, 32.50 percent gross margin and 21.80 percent operating margin.
