United Microelectronics approves ~US$3.2B expansion budget
UMC's fourth-quarter outlook calls for low-single-digit wafer-shipment growth and capacity utilization in the low-90% range.
Sentiment and the balance of points
Rhea-AI Sentiment reads the wording of the document, how positive or negative its language is on a 1 to 5 scale. The balance of points shown with the takes weighs what the document actually discloses, so the two can disagree, for example when a trial that missed its main goal is described in upbeat language.
Rhea-AI Filing Summary
United Microelectronics Corporation (UMC) reported third-quarter 2026 revenue of NT$74.24 billion, up 8.0% from the second quarter and 25.6% year over year. Gross margin was 34.0%, operating margin was 25.1%, and net income attributable to parent shareholders was NT$16.43 billion; earnings per share were NT$1.32. Wafer shipments grew 7.3% to more than 1.2 million 12-inch-equivalent wafers, capacity utilization reached 92%, and 22nm revenue accounted for 18.3% of wafer sales; 22/28nm revenue represented 35%.
For fourth-quarter 2026, UMC expects wafer shipments to increase by low-single digit, USD ASP to remain firm, gross margin to be comparable to the preceding quarter, and capacity utilization to be in the low-90% range. The board approved NT$102,781 million of capital-budget execution for capacity deployment, funded from working capital. UMC also reported that the board approved an additional capital-expenditure budget of approximately US$3.2 billion to accelerate expansion. Its 2026 CAPEX outlook is US$2.0 billion.
How this balance works
Rhea-AI gives every point it takes from this document a weight. Minor counts 1, Moderate 3 and Major 9, so one Major point outweighs several Minor ones. The bar adds up the weights on each side, and when neither side holds more than 65% of the total the balance reads Mixed.
It reads the document as published, with the same rules for every company, and it does not look at what the market expected or at how the stock traded, so a point can be objectively good on a day the stock falls.
Rhea-AI Sentiment measures something else, the tone of the wording.
Positive
- Moderate pointQ3 revenue increased 25.6% year over year.
Negative
- None.

‧Gross margin: 34.0%; Operating margin: 25.1%
‧Revenue from 22/28nm: 35%

Taipei, Taiwan, ROC – October 28, 2026 – United Microelectronics Corporation (NYSE: UMC; TWSE: 2303) (“UMC” or “The Company”), a leading global semiconductor foundry, today announced its consolidated operating results for the third quarter of 2026.
Third quarter consolidated revenue was NT$74.24 billion, increasing 8.0% from NT$68.73 billion in 2Q26. Compared to a year ago, 3Q26 revenue increased 25.6%. Consolidated gross margin for 3Q26 was 34.0%. Net income attributable to the shareholders of the parent was NT$16.43 billion, with earnings per ordinary share of NT$1.32.
Jason Wang, CEO of UMC, said, “In the third quarter, we saw healthy demand across all market segments, driving a 7.3% growth in wafer shipments to more than 1.2 million 12-inch equivalent wafers, a record high. Our overall fab utilization rate reached 92%, with several 12-inch fabs operating at full capacity while 8-inch operations also saw a strong recovery. By technology node, our 22/28nm business had another record-breaking quarter, with 22nm revenue now accounting for 18.3% of wafer sales as customers continue to tape out new products including display driver, automotive radar, and Wi-Fi ICs. In new business areas, active customer engagement for advanced packaging and silicon photonics remains robust. We expect these engagements to translate into accretive growth over the coming quarters as we ramp existing projects and support new product tape-outs.”
CEO Wang added, “Looking ahead to the fourth quarter, we expect the positive demand momentum to sustain, supporting stable shipments and utilization rate. Revenue from our specialty technologies portfolio will continue to grow sequentially, driven in part by the ramp-up of our advanced packaging and silicon photonics businesses. We have seen a significant increase in demand for these new business areas, and we are in the process of converting some existing capacity to address near-term unfulfilled demand. In the longer run, our dual track expansion plan in Singapore and Tainan will be crucial to ensure UMC’s capacity growth can keep pace with our
customers’ needs. We are pleased to announce our Board of Directors today approved an additional capital expenditure budget of approximately US$3.2 billion, which will enable us to accelerate our expansion schedule as we continue to align with customers on their product roadmaps and requirements.”
CEO Wang said, “In the third quarter, UMC received the honor of being named one of Asia’s top employers of choice in the HR Asia Best Companies to Work for in Asia Awards 2026. We are proud to win this award for the third time, recognizing the company’s ongoing effort to strengthen and expand our talent development programs, comprehensive employee benefits, and community engagement opportunities. Through these initiatives, we strive to create a more supportive workplace where our people can grow and thrive, while building a strong foundation for UMC’s long-term success.”
