JASM started production in late 2024 and recorded a full-year loss of NT$9.8 billion in 2025. The turnaround in Q1 2026 was driven by recovering mature-node demand, higher utilization, improved yields, and stabilizing depreciation costs.
Meanwhile, TSMC’s Arizona fab also saw strong performance, with Q1 net profit of NT18.81billion∗∗andTSMC’sshareat∗∗NT18.81billion∗∗andTSMC’sshareat∗∗NT16.91 billion.
