Taiwan Semiconductor Manufacturing Company Limited, TSM

In a client communication, BofA analyst Haas Liu highlighted that TSMC’s American fabrication facilities are making substantial headway. The Arizona plant generated NT$45 billion in Q2 revenue, marking a 17% sequential increase and a remarkable 145% year-over-year expansion, contributing 4% to TSMC’s consolidated revenue.

Liu’s analysis reveals that TSMC’s net profitability for Arizona operations, when excluding government subsidies, maintained a healthy 38% in Q2 2026. This represents a dramatic turnaround from the approximately -90% loss recorded in 2025, demonstrating meaningful operational improvements.

The company’s board recently authorized $29 billion in American capital allocations, essentially doubling the previous year’s commitment. Liu anticipates capital expenditures will reach the guidance midpoint of $62 billion for 2026, with projections suggesting a potential escalation to $80-$85 billion in 2027.

Profitability Metrics Stay Robust

Even with substantial capital deployment, BofA forecasts TSMC’s gross profitability will remain resilient in the high-60% territory. Liu attributed this strength to robust appetite for high-performance computing solutions and premium mobile processors as primary margin stabilizers.

Depreciation expenses are projected to expand at approximately 20% compound annual growth rate between 2026 and 2028, reflecting the acceleration of cutting-edge and specialized technology capabilities. This encompasses a planned collaboration with Sony for image sensor manufacturing, scheduled to launch in 2029.

BofA increased its TSM valuation target to $590 from the previous $490 mark, maintaining its Buy designation. This represents potential appreciation of roughly 37% from Tuesday’s opening level.
