TSMC to Invest $165 Billion in U.S., Build up to 12 Arizona Plants

TSMTSM

Taiwan Semiconductor Manufacturing Company plans to invest $165 billion in U.S. production, including up to a dozen new plants in Arizona under a deal tied to Trump-era tariffs. The expansion aims to boost advanced chip capacity and onshore manufacturing to meet rising AI and high-performance computing demand.

1. Undervalued Positioning and Growth Drivers

Taiwan Semiconductor Manufacturing Company (TSMC) trades at a forward price-to-earnings ratio of 24.5, well below peer averages of 39.4 and 34.0 for leading AI chip producers. The company has expanded its share of the advanced-node market to 60% in 2025, driven by continued price increases on 5-nanometer and 3-nanometer wafers. Management has signaled further price hikes on advanced nodes through 2029, underpinning expectations for mid-teens annualized revenue growth. Meanwhile, early ramp of 2-nanometer production has delivered yields of 70%, surpassing internal targets by 10 percentage points and positioning TSMC to capture the next wave of AI processor demand.

2. Fourth-Quarter Earnings and Profit Forecast

Analysts forecast TSMC will report a 28% year-over-year jump in fourth-quarter net profit to a record high, driven by sustained demand for AI infrastructure. Consensus sales estimates call for 17.7% growth over the same period, following a 20.4% increase in third-quarter revenue. Earnings per share are expected to rise 30.3%, reflecting margin expansion from pricing power on advanced nodes. Wall Street strategists have revised their earnings estimates upward over the past month, with the average target now 5% above pre-report levels ahead of the January 15 release.

3. U.S. Expansion and Onshoring Strategy

As part of a broader trade-policy agreement, TSMC plans to invest up to $165 billion in U.S. manufacturing through 2029, with the potential to build as many as 12 new fabrication facilities in Arizona. The first U.S. plant, scheduled to begin volume production in late 2026, will mirror the Taiwan advanced-node process and aims to run at 80% capacity by 2028. Management has indicated plans to add Vera Rubin GPU assembly lines in Arizona alongside existing Blackwell production, supporting customer onshoring requirements and reducing supply-chain risks.
