UMC reported May 2026 revenue of NT$22.94B, up 17.8% YoY and +1.2% MoM, marking continued sequential improvement off a soft 2025 base. The double-digit YoY acceleration points to firming mature-node foundry demand, likely tied to AI-adjacent power/interface ICs and inventory replenishment at fabless customers.

The board has approved the issuance of the company's first domestic unsecured convertible corporate bond. This represents a capital-raising event that could result in future share dilution upon conversion, making it materially relevant to equity investors. Full body available on MOPS.

UMC reported September 2025 revenue of NT$19.16B, down 7.2% YoY and 4.39% MoM, signaling continued softness in mature-node foundry demand. The sequential decline alongside the YoY contraction suggests UMC remains outside the AI/HBM tailwind benefiting leading-edge peers, with legacy logic and specialty nodes still working through inventory normalization.

UMC reported October 2025 revenue of NT$19.93B, up 5.2% YoY and 4.01% MoM, marking sequential acceleration as foundry utilization improves. The steady growth signals stabilizing mature-node demand, with AI-related specialty processes (RF, power management for AI servers) likely supporting the modest cyclical recovery.

UMC reported November 2025 revenue of NT$21.29B, essentially flat YoY at -0.36% but up a healthy +6.86% MoM. The sequential rebound suggests stabilizing mature-node foundry demand, though the lack of YoY growth signals UMC is not capturing the AI-driven upcycle benefiting leading-edge peers like TSMC.

UMC reported December 2025 revenue of NT$21.23 billion, up 5.91% year-over-year but essentially flat month-over-month at -0.29%. The modest YoY growth suggests stable mature-node foundry demand, though the lack of sequential momentum points to a still-muted recovery in non-AI semiconductor cycles where UMC is primarily exposed.

UMC reported January 2026 revenue of NT$19.28B, up 1.66% YoY but down 9.2% MoM, reflecting typical Q1 seasonality in mature-node foundry demand. The modest YoY growth suggests stable but unspectacular utilization, with limited direct exposure to the AI/HBM cycle that is lifting leading-edge peers like TSMC. Investors should watch for signs of recovery in consumer and communications end-markets that drive UMC's 28nm/22nm specialty node mix.

UMC reported February 2026 revenue of NT$20.86B, up 5.3% YoY and rebounding 8.2% MoM. The sequential acceleration suggests improving foundry utilization, consistent with broader semiconductor cycle recovery driven by AI-adjacent mature-node demand, though the modest YoY growth reflects UMC's lagging exposure to leading-edge AI/HBM versus TSMC.

UMC reported March 2026 revenue of NT$19.35B, up 6.33% YoY but down 7.27% MoM. The modest YoY growth alongside sequential softness suggests mature-node foundry demand remains steady but lacks the AI/HBM tailwind benefiting leading-edge peers.
