TSMC Hits Record Profits but Stock Stalls on Margin and Capex Fears

Key points

• TSMC reported third-quarter revenue of $46.7 billion and EPS of $4.60, beating consensus estimates.
• Full-year revenue growth guidance was raised to approximately 44%, up from 30% earlier in the year.
• Gross margin slipped to 66.4% from 67.7%, driven by the initial ramp of 2nm technology and overseas fab costs.
• Capital expenditure is planned at $60 billion to $64 billion for 2026, with management indicating spending will be 'even more significantly higher' through 2028.
• The stock has fallen 7.77% in the past week, trading 13.3% below its 52-week high of $487.47.
• Analysts maintain a positive outlook, with 20 of 21 rating the stock a Buy or Strong Buy and a consensus price target of $578.22.

Background

TSMC has been a central beneficiary of the global AI infrastructure boom, with JPMorgan forecasting AI spending to reach $1.4 trillion by 2030. Recent market volatility, including a sharp selloff in South Korea's KOSPI index, has highlighted investor concerns about the sustainability of AI investment. TSMC's stock had previously surged, outperforming the S&P 500 year-to-date, but recent pullbacks suggest caution regarding valuation and execution risks. The company's expansion into the US and Japan marks a significant shift from its traditional Taiwan-centric manufacturing model.

How outlets are covering it

24/7 Wall St. emphasizes the tension between record profits and margin dilution, noting that the 2nm ramp and overseas costs are pressuring profitability despite strong revenue. CNBC highlights the 'fierce' competition for TSMC's manufacturing capacity, with major tech firms like Nvidia, Apple, and Broadcom vying for access to advanced nodes. Asia Times focuses on the capital efficiency of TSMC's global expansion, questioning whether the massive capital expenditure will yield sufficient returns given the higher costs of overseas manufacturing. All sources agree on the strength of AI demand but differ on the primary risk: 24/7 Wall St. points to margin compression, CNBC to supply constraints, and Asia Times to the financial sustainability of the expansion program.

Why it matters

TSMC's performance is a bellwether for the broader AI and semiconductor industry. Its ability to manage margin pressure while executing a massive capital expansion will influence investor confidence in the AI infrastructure buildout. If TSMC can maintain profitability despite higher costs, it may validate the long-term demand for AI chips. Conversely, if margins continue to erode or capital spending outpaces revenue growth, it could signal a slowdown in the AI boom. The stock's reaction to strong earnings also reflects broader market sentiment on technology valuations and the sustainability of current growth rates.

What to watch

Investors will watch TSMC's fourth-quarter earnings report for signs of margin stabilization and continued revenue growth. The company's ability to ramp 2nm yields and manage overseas fab costs will be critical. Additionally, the timing of volume production at its Arizona and Japan facilities will be key indicators of execution success. Analysts will also monitor capital expenditure trends in 2027, with some forecasts suggesting spending could reach $85 billion to $90 billion. Any signs of weakness in AI demand or a pullback by hyperscalers could impact TSMC's outlook.
