UMC reported September 2026 sales of NT$25.35 billion, up 27.22 percent from the same month a year earlier, while UMC stock was trading at EUR 20.40 at Lang & Schwarz on October 12, 2026 at 11:33 a.m. CEST. Business Wire reported the sales figure on October 6, 2026.

Sales momentum reaches the third quarter

UMC's January through September 2026 sales reached NT$204.01 billion, an increase of 16.08 percent from the same period in 2025, according to Business Wire. September growth therefore ran 11.14 percentage points above the nine-month rate, giving the latest monthly figure greater weight than the cumulative trend.

The company also reported second-quarter 2026 consolidated revenue of NT$68.73 billion, up 17.00 percent from the year-earlier quarter, with a gross margin of 32.50 percent. The same Business Wire release identified UMC as a global semiconductor foundry listed on the NYSE and Taiwan Stock Exchange.

Why does the bond issue matter?

On October 5, 2026, UMC priced US$1.8 billion of unsecured overseas convertible bonds in two US$900 million tranches. Stock Titan reported that the bonds carry a 0.00 percent coupon and could dilute existing shareholders by 2.34 percent if fully converted.

The proceeds are designated for machinery, equipment and plant construction. The conversion prices of NT$179.19 and NT$202.06 stand above UMC's TWSE closing price of NT$152.50 on October 5, 2026, which limits immediate conversion pressure but leaves future dilution tied to a stronger share price.

Three dated operating milestones

On July 29, 2026, UMC reported second-quarter revenue of NT$68.73 billion, up 17.00 percent year over year. On October 5, 2026, it priced the US$1.8 billion convertible-bond issue with 2.34 percent potential dilution. On October 6, 2026, September sales reached NT$25.35 billion, up 27.22 percent year over year.

What dates come next?

UMC's bond issue is scheduled for October 13, 2026, while the next quarterly report is listed for October 28, 2026. The two dates frame the near-term sequence: financing first, operating results next.
