Key Terms

capex financial

Capex, short for capital expenditures, refers to the money a company spends to buy, upgrade, or maintain physical assets such as buildings, equipment, or technology. It matters to investors because these investments can help a company grow and improve its long-term performance, but they also represent significant costs that can impact profitability and cash flow.

silicon photonics technical

Silicon photonics is the technology that uses tiny structures etched into silicon chips to generate, control and detect light for moving data and sensing, essentially putting optical fiber functions onto a computer chip. For investors, it matters because it can dramatically increase data speed and energy efficiency in data centers, telecom networks and advanced sensors, potentially lowering costs and enabling new products much like replacing many metal wires with faster, low-power optical highways.

photonic ics technical

Photonic ICs are chips that use light instead of electricity to carry and process signals, integrating tiny lasers, waveguides, modulators, and detectors on a single piece of semiconductor much like electronic integrated circuits route electrons. They matter to investors because they can change the speed, energy use, and cost of data transmission and sensing—so company positions in manufacturing, design, and supply chains can affect future revenue and margins as markets like telecom, data centers, and lidar evolve.

fabless technical

A fabless company designs and sells semiconductor chips but does not own the factories that make them; instead it hires specialized manufacturers to produce the physical chips. Like a clothing designer who sketches garments and contracts a factory to sew them, this model keeps upfront equipment costs low but exposes the business to manufacturing availability, lead times and partner pricing—factors investors watch because they affect cash needs, margins and supply-chain risk.

2026 CAPEX raised to US$2bn to support phased expansion plan

Q2 2026 operating income increases 32.6% QoQ while Q3 utilization to exceed 90%

Second Quarter 2026 Overview¹:

Revenue: NT$68.73 billion (US$2.18 billion)
Gross margin: 32.5%; Operating margin: 21.8%
Revenue from 22/28nm: 37%
Capacity utilization rate: 85%
Net income attributable to shareholders of the parent: NT$42.26 billion (US$1.34 billion)
Earnings per share: NT$3.39; earnings per ADS: US$0.537

TAIPEI, Taiwan--(BUSINESS WIRE)-- United Microelectronics Corporation (NYSE: UMC; TWSE: 2303) (“UMC” or “The Company”), a leading global semiconductor foundry, today announced its consolidated operating results for the second quarter of 2026.

Second quarter consolidated revenue was NT$68.73 billion, increasing 12.6% from NT$61.04 billion in 1Q26. Compared to a year ago, 2Q26 revenue increased 17.0%. Consolidated gross margin for 2Q26 was 32.5%. Net income attributable to the shareholders of the parent was NT$42.26 billion, with earnings per ordinary share of NT$3.39.

Jason Wang, CEO of UMC, said, “In the second quarter, our wafer shipments increased 10.6% quarter-on-quarter, driven by strong demand in the communication and consumer segments, further improving utilization rate to 85%. Revenue from our 22/28nm business continues to set record highs, with 22nm revenue representing 17.5% of second-quarter sales. Earlier this month, we announced the company’s first mass-production delivery of 12-inch photonic ICs to a customer, a major milestone for UMC that demonstrates the company’s high-volume silicon photonics manufacturing capability on 12-inch wafers as we prepare to launch our silicon photonics platform available for general customer use in 2027.”

CEO Wang added, “Looking ahead to the third quarter, we expect demand momentum to remain stable across the computer, communication, and consumer segments, with shipments projected to increase by high-single digits. Driven by strong demand for power management ICs, sensors, and microcontrollers, our 8-inch portfolio is seeing a strong rebound, and utilization is expected to improve significantly in the third quarter. With our 12-inch capacity already at a healthy utilization rate supporting core businesses, we must also prepare in advance to ensure UMC is well positioned to capture future opportunities driven by AI. To ensure we are ready to scale rapidly to support our customers, we announced today that our Board of Directors has approved a plan to expand cleanroom capacity at our Singapore P4 facility and to construct a new fab in Tainan, Taiwan. The plan will be executed in phases, enabling UMC to remain focused on capital discipline while flexibly deploying capacity to fulfill customer demand. As a result, 2026 capital expenditure budget will be revised upward to US$2 billion.”

CEO Wang said, “In the second quarter, UMC was proud to be selected for inclusion in the FTSE4Good TIP Taiwan ESG Index, which evaluates top-performing Taiwan-listed companies based on international sustainability standards, for the tenth consecutive year. For investors interested in learning more about UMC’s sustainability targets and progress, the company’s 2025 Sustainability Report will be available on our website by the end of July.”
