TAIPEI, July 29 (Reuters) – Taiwanese chipmaker United Microelectronics Corp (UMC) said on Wednesday that its board ​approved an expansion plan, including ‌additional cleanroom capacity at its Singapore facility and a new fab building at its flagship Tainan campus in Taiwan, to meet growing ‌AI-driven ​demand.

• “The plan will ⁠be executed in phases, ⁠enabling UMC to remain ocused 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,” said CEO Jason ⁠Wang.

• United Microelectronics focuses on ​more mature nodes, unlike Taiwan Semiconductor Manufacturing, ​the world’s largest contract chipmaker, which ‌is investing big in the most advanced 2 and 1 nanometre technology to power artificial intelligence applications.

• UMC ⁠reported second-quarter revenue of T$68.73 billion ($2.12 billion), up 17% from a year earlier, while net ⁠income ‌was up 374.7% at T$42.26 ⁠billion.

• UMC’s shares have risen ​120% ‌so far this year, outperforming ​a 38.24% ⁠gain in the broader market. The stock closed down 9.69% on Wednesday ahead of its earnings release.
