UMC

UMC's stock price has seen a significant increase of 182.57% in the past six months and 228.28% year-to-date, driven by strong sales growth, an upbeat capacity outlook, and optimism surrounding late-July earnings. Higher capital spending plans and steady demand in mature-node and specialty chip businesses have also contributed. Second-quarter 2026 revenue increased by 17.0% year-over-year, with operating income rising sharply due to improved factory utilization and profitability. UMC raised its 2026 capital expenditure budget to support expansions in Singapore and Tainan, anticipating growing demand from AI-related connectivity, power, and photonics. Monthly sales for July 2026 increased by 18.98% year-over-year. An insider sale by UMC's CFO in September 2026 caused temporary selling pressure but was absorbed by sustained institutional demand. The company completed NT$4.79 billion in domestic convertible bond funding and plans up to $1.8 billion in overseas convertible bonds, which could introduce equity dilution risks.
