Taiwan Semiconductor Manufacturing Co Ltd (NYSE:TSM) is ramping up next-generation chip production and global capacity, with analysts broadly optimistic on AI-driven growth while flagging valuation and concentration risks.

Advanced Nodes And Capacity Expansion

Taiwan Semiconductor Senior Vice President and Deputy Co-COO Cliff Hou at the company’s 2026 Technology Symposium in Silicon Valley last week said the company expects its 2-nanometer capacity to grow at a 70% compound annual rate from 2026 to 2028, with five fabs already moving into volume production, Focus Taiwan reported on Tuesday.

He added that the first-year 2nm output will exceed the initial 3nm production by 45%, while the 3nm capacity is set to expand about 25% annually.

Hou also highlighted rapid scaling in advanced packaging, with CoWoS capacity projected to grow by more than 80% annually and SoIC capacity by more than 90%.

Global Expansion And AI Demand Support

Hou said Taiwan Semiconductor is also expanding globally, with its Arizona fab expected to boost output by 80% in 2026 and its Japan facility by 130%.

Analysts link this expansion to strong AI-driven demand.

Goldman Sachs cited growth in 2nm output and Chip on Wafer on Substrate (CoWoS) services as key drivers behind its bullish outlook, while multiple brokerages—including CLSA, Citigroup, Nomura, and HSBC—set elevated price forecasts, reflecting confidence in sustained demand, Focus Taiwan reported on Tuesday.

Valuation And Concentration Risks

Cathay Futures Consultant analyst Tsai Ming-han said Taiwan Semiconductor’s valuation remains within its historical range, noting the stock trades at a price-to-earnings ratio below 25, compared with a typical 20–30 band, with earnings expected to reach about NT$100 per share in 2026.

However, he warned that if the stock approaches NT$3,000—pushing the P/E above 29—it could signal overheating and pressure the broader market.

UOB Kay Hian’s Qi Wang told CNBC on Tuesday that Taiwan’s move to raise the single-stock cap will boost flows into Taiwan Semiconductor but also heighten long-term concentration risks.

Wang expects the higher cap—from 10% to 25%—to drive about $30 billion to $40 billion in domestic inflows into Taiwan Semiconductor, calling the change a positive step as regulators address fund managers’ difficulty tracking benchmarks in which Taiwan Semiconductor dominates.

He noted the stock accounts for over 40% of the Taiex and more than 60% of the MSCI Taiwan Index, making the earlier cap restrictive.

However, Wang warned that the policy could reinforce Taiwan’s dependence on Taiwan Semiconductor, increasing concentration risk for both the economy and markets.

He said the inflows could support the stock but worsen the “one-trick pony” concern over time.

On fundamentals, Wang said investors should focus on AI-driven growth rather than price forecasts.

He said Taiwan Semiconductor remains “very well-positioned as a monopoly in advanced AI semiconductors” and a “must-own name” as long as AI capital spending—projected to grow roughly 50% to 60% in the U.S.—remains intact, while cautioning that investors may need to reassess growth expectations beyond 2026.

TSM Price Action: Taiwan Semiconductor shares were down 3.66% at $390.15 during premarket trading on Tuesday. The stock is approaching its 52-week high of $414.50, according to Benzinga Pro data.
