• Revenue: NT$59.13 billion (US$1.94 billion)
• Gross margin: 29.8%; Operating margin: 18.8%
• Revenue from 22/28nm: 35%

TAIPEI, Taiwan--(BUSINESS WIRE)--October 29, 2025--

United Microelectronics Corporation (; ) ("UMC" or "The Company"), a leading global semiconductor foundry, today announced its consolidated operating results for the third quarter of 2025.

Third quarter consolidated revenue was NT$59.13 billion, increasing 0.6% from NT$58.76 billion in 2Q25. Compared to a year ago, 3Q25 revenue decreased 2.2%. Consolidated gross margin for 3Q25 was 29.8%. Net income attributable to the shareholders of the parent was NT$14.98 billion, with earnings per ordinary share of NT$1.20.

Jason Wang, co-president of UMC, said, "In the third quarter, we observed demand growth across most market segments, which drove a 3.4% increase in wafer shipments and improved utilization rate to 78%. In particular, we benefited from a pick-up in sales of smartphones and notebooks, driving replenishment orders from customers. Our 22nm technology platforms continue to provide us with differentiation in the market, with 22nm revenue now accounting for more than 10% of total sales. In 2025 alone, we are projecting over 50 product tape-outs and we expect 22nm contribution to continue increasing in 2026. Aligned with our strategy of providing customers with highly differentiated specialty technologies, we recently announced the readiness of our 55nm BCD platform. In addition to mobile and consumer applications, the new platform is also compliant with the most rigorous automotive standards for automotive and industrial uses."

Co-president Wang added, "Looking ahead to the fourth quarter, we are anticipating wafer shipments to be comparable with third quarter's volume, wrapping up 2025 with shipment growth in the low teens. UMC continues to deliver competitive process technologies that enable diverse applications, which positions the company to benefit from a broad-based market recovery, with 22nm logic and specialty platforms in particular expected to drive growth."

Co-president Wang said, "UMC has been a pioneer in the industry for climate action as the first semiconductor foundry worldwide to pledge net zero greenhouse gas emissions. Demonstrating our commitment, UMC once again led the industry in receiving Science Based Targets initiative (SBTi) validation of our emissions reduction targets under the most stringent climate standard. In addition to executing on reduction programs within our own operations, we are also working closely with partners to address the carbon footprint of our upstream and downstream value chain as we progress towards net zero by 2050."
