Key Takeaways:
Taiwan Semiconductor Manufacturing Co.'s stock has nearly doubled over the past 12 months, yet the company's central role in the AI supply chain — and a supply crunch that CEO C.C. Wei says will persist into 2027 — suggests the rally may have further to run.
Taiwan Semiconductor Manufacturing Co. (NYSE:TSM) has become the most consequential company in the AI infrastructure buildout, fabricating chips for Nvidia Corp., Advanced Micro Devices Inc., Broadcom Inc. and every major hyperscaler designing custom silicon. The stock closed at $425.83 on June 17, up 40.8% year to date and 99.6% over the past 52 weeks, giving the company a $2.29 trillion market capitalization.
"Global chip supply will not meet AI-fueled demand for years," Wei told investors during the company's first-quarter earnings call, reiterating a 2026 revenue growth outlook above 30% in U.S. dollar terms. The company raised its AI revenue compound annual growth rate forecast to the mid-to-high 50% range through 2029, underscoring the duration of the spending cycle.
First-quarter results bore out the optimism. Revenue climbed 39% year over year to $35.9 billion, exceeding the company's own guidance, while gross margin expanded 740 basis points to 66.2%. High-performance computing — the segment housing AI and data center workloads — accounted for 61% of total revenue, and advanced process technologies of 7 nanometers and below represented 74% of wafer revenue. Earnings per share of $3.49 beat consensus estimates by 8.39%.
Supply constraints underpin TSM's pricing power
Wei has repeatedly said that demand for leading-edge nodes and advanced packaging (CoWoS and SoIC, which stack chips vertically to improve performance) exceeds available capacity. The company expects conditions to remain tight into 2027, giving it unusual pricing leverage in an industry historically prone to boom-bust cycles.
TSMC is expanding N3 and N2 production globally while investing aggressively in future nodes such as A14. Capital spending is trending toward the high end of the company's $52 billion to $56 billion range for 2026. New fabrication facilities in Arizona, Japan and Germany are part of a $250 billion global investment plan that also serves to diversify manufacturing away from Taiwan, a strategic hedge against geopolitical risk.
The company's May revenue report reinforced the trajectory. Net revenue for the month reached NT$416.98 billion ($12.9 billion), up 30.1% from a year earlier. Cumulative revenue for the first five months of 2026 rose 30% to NT$1.96 trillion.
Valuation debate: premium or justified?
At roughly 25 times forward earnings, TSM trades slightly below the Computer and Technology sector average of 25.4 times, according to Zacks data. That represents a premium to its own five-year median of 21.3 times — but the multiple compression is less dramatic than the stock's price appreciation suggests, because earnings have grown faster than the share price.
Bernstein projects 28% compound annual EPS growth through 2028, a trajectory that would make the current multiple look conservative if sustained. Full-year 2025 EPS came in at $10.65, up 76.3% from $6.04 in 2024, and the first quarter of 2026 already delivered $3.49 per share.
The bull case rests on three pillars: the Nvidia partnership to integrate AI into TSMC's own fabs, 2nm mass production with early yields that Wei described as strong, and the $250 billion U.S. investment that reduces the geopolitical discount investors have historically applied to Taiwan-based assets. Wei dismissed Samsung Foundry's ambition to catch up as a "pipe dream" during the earnings call.
Risks that could derail the thesis
The bear case is not about demand — it is about concentration and geopolitics. TSM's top 10 customers account for 84% of revenue, meaning any shift in spending by a single large chip designer could create a material gap. A Marlin Semiconductor patent dispute now before the U.S. International Trade Commission adds legal uncertainty, and Taiwan's consideration of stricter export controls on advanced AI chips to China could pressure customer access.
A serious escalation in the Taiwan Strait remains the tail risk that no valuation model can price. Wei himself flagged talent and water shortages as operational concerns, noting at a recent ceremony that he had considered deploying water trucks last month.
For investors, the question is whether TSM at 25 times forward earnings — with 30% revenue growth, 66% gross margins and a supply crunch that extends into 2027 — represents a fair price for the only manufacturer capable of producing the world's most advanced chips. The stock's 10-year return of 2,019% suggests that betting against TSM's compounding power has been a losing trade.
