TSMC announced an additional $100 billion investment in Arizona, expanding their total U.S. investment to $165 billion. This includes plans for three more wafer fabs, two advanced packaging facilities, and an R&D center. The expansion will result in about 30% of TSMC's 2nm and more advanced capacity being located in Arizona. The company expects robust AI-related demand in 2025, projecting AI accelerator revenue to double and aiming to double their CoWoS capacity. TSMC forecasts a 40% CAGR for AI accelerator revenue over the next five years. Despite overseas expansion causing margin dilution, TSMC maintains a long-term gross margin target of 53% or higher.Disclaimer: This earnings call summary is generated by AI and is for informational purposes only.
