UMC raises 2026 capex to $2 billion, plans new fabs for silicon photonics and advanced packaging

United Microelectronics Corporation revised its 2026 capital expenditure upward to $2 billion from $1.5 billion and announced board approval of nearly $5 billion in spending for cleanroom and fab construction across 2026 and 2027. The company will expand cleanroom capacity at its Singapore P4 facility for silicon photonics and construct a new fab in Tainan, Taiwan, for advanced packaging, with the Tainan project representing the P7 and P8 phases of its 12A site. Second-quarter consolidated revenue reached TWD 68.73 billion, a 12.6% sequential increase, while net income attributable to shareholders of the parent was TWD 42.26 billion, boosted by TWD 30 billion in investment and dividend income. Gross margin rose to 32.5% and utilization climbed to 85%, with third-quarter guidance calling for wafer shipments to increase by high single digits, gross margin in the mid-30% range, and utilization exceeding 90%. CEO Jason Wang projected AI-related revenue of approximately $300 million for 2026, with a target to exceed $1 billion within three years, and noted that the addressable market for the company's advanced packaging solutions is expected to more than double by 2030.

UMC raises 2026 capex to US$2 billion, expands Singapore and Taiwan fabs for AI demand

United Microelectronics Corp has approved an expansion plan that includes additional cleanroom capacity at its Singapore facility and a new fab building at its flagship Tainan campus in Taiwan, raising its 2026 capital expenditure budget to US$2 billion. CEO Jason Wang said the plan will be executed in phases to maintain capital discipline while flexibly deploying capacity to meet customer demand driven by artificial intelligence. The company focuses on mature nodes, unlike TSMC which invests heavily in advanced 2 and 1 nanometre technology. UMC reported second-quarter revenue of T$68.73 billion, up 17% from a year earlier, while net income surged 374.7% to T$42.26 billion. Its shares have risen 120% so far this year, outperforming the broader market's 38.24% gain, though the stock closed down 9.69% on Wednesday ahead of the earnings release.

Wedbush Says TSMC May Raise Mature-Node Prices in Early 2027

Wedbush has indicated that Taiwan Semiconductor Manufacturing may raise prices for mature-node manufacturing processes beginning in early 2027, marking the company's first adjustment to mature-node pricing in more than three years. Final pricing decisions are expected later this year. The firm noted that any pricing increase by Taiwan Semiconductor could signal improving conditions across the mature-node foundry market and support stronger industry pricing trends, reflecting healthier demand dynamics for legacy chip production. Wedbush added that other foundry companies, including United Microelectronics, GlobalFoundries, and Tower Semiconductor, could also benefit if industry pricing strengthens.

UMC starts silicon photonics mass production in Singapore

United Microelectronics has begun mass production of silicon photonics wafers at its Singapore facility, targeting demand for high-speed optical interconnects in AI and hyperscaler data center networks. The milestone was achieved in partnership with SILITH, combining SILITH's proprietary silicon photonics architecture with UMC's 12-inch manufacturing platform, moving from development to production readiness in 18 months. UMC also plans to make its own 12-inch silicon photonics platform available for customer product development by 2027. The company's stock fell nearly 5% in Taiwan during Tuesday's session before paring losses to trade 1.6% lower.

Wedbush Says UMC Could Be 2026’s Biggest Winner as TSMC Relocation Spurs Demand

Wedbush has identified United Microelectronics as a potential standout for 2026, arguing that geopolitical shifts pushing chip buyers to diversify supply could benefit the Taiwanese foundry. UMC, Taiwan’s second-largest semiconductor foundry, operates factories in Singapore and Japan, positioning it to capture demand if TSMC moves mature-node work outside Taiwan. The firm rates UMC Outperform with a $12 price target, while the stock has already surged roughly 263% over the past year and 30% in the last five days. In the first quarter of 2026, UMC reported revenue of $1.93 billion, up 7% year-over-year, and net income of $511 million, a 10% jump. CEO Jason Wang noted firming mature-node utilization driven by edge AI and automotive chip designers seeking supply chain resilience.
