TL;DR Summary
TSMC’s third-quarter results strengthened the business case behind its expansion. Leading-edge demand drove higher revenue and operating profit, 2nm gained a larger share of wafer sales, and free cash flow improved substantially.
The trade-off remains visible: new technology brings additional revenue but initially weighs on margins. Meanwhile, HPC accounts for an increasing proportion of the business.
- Revenue reached US$46.72 billion, increasing 41.2% year over year.
- Operating income increased 75%, while gross margin declined sequentially to 66.4%.
- 2nm represented 8% of wafer revenue, up from 3% in Q2.
- Free cash flow increased to NT$476.56 billion, from NT$287.36 billion.
- Our updated probability-weighted forward value is approximately US$460 per ADR, versus US$440 previously.
The business outlook has improved. Whether the shares offer an attractive entry point still depends on the price paid and the investor’s tolerance for capital intensity and geopolitical risk. investor.tsmc.com
Quarter Recap
TSMC reported Q3 revenue of NT$1,494.24 billion, equivalent to US$46.72 billion. Revenue increased 50.9% year over year in NT dollars and 41.2% in US dollars.
Net income attributable to shareholders reached NT$763.06 billion, increasing 68.7%. Diluted earnings were NT$29.43 per ordinary share, or US$4.60 per ADR.
Revenue exceeded management’s previous US$44.6–45.8 billion guidance. Gross margin of 66.4% was within guidance, while operating margin of 58.7% exceeded the projected 56–58% range. investor.tsmc.com
Sequential comparisons require care. Q2 included Vanguard-related investment gains that did not recur in Q3. Consequently, reported net income increased 8% sequentially, while operating income increased 14.3%. The two measures describe different aspects of the quarter rather than contradictory performance. investor.tsmc.com
Key Highlights
Leading-edge demand continues to expand
The 2nm contribution increased from 3% to 8% of wafer revenue, while 3nm increased from 30% to 33%. Technologies at 7nm and below collectively represented 79%.
HPC revenue increased 22% sequentially and accounted for 68% of total revenue. Smartphone and automotive revenue also increased sequentially, by 10% and 23%, respectively. HPC remains a broader category than AI alone; its entire revenue should not be described as AI revenue. investor.tsmc.com
These figures support our interpretation that TSMC’s growth is being realized through shipments and technology adoption—not simply through expectations about future demand.
Cash conversion improved
Operating cash flow rose to NT$919.77 billion, while capital expenditure declined sequentially to NT$443.21 billion. Free cash flow consequently increased to NT$476.56 billion.
Cash and marketable securities reached NT$4,016.98 billion. investor.tsmc.com
This updates an important part of our Q2 assessment. Capital intensity remains a concern, but the latest quarter does not support describing cash conversion as continuously deteriorating.
Growth continues alongside ramp costs
Management attributed the sequential gross-margin decline primarily to the initial N2 ramp.
For Q4, TSMC expects revenue of US$52.3–54.3 billion, gross margin of 65–67%, and operating margin of 56.5–58.5%. Its presentation forecasts approximately 44% full-year US-dollar revenue growth. investor.tsmc.com
Our interpretation is that demand remains strong, but investors should not assume that revenue growth will translate into proportional margin expansion.

SWOT Analysis
TSMC combines technology leadership and substantial cash generation with a business model that requires large, continuing investment.
The percentage ranges below are illustrative changes in modeled equity value, not predicted stock-price movements. Each is sensitivity-derived from explicit assumptions. They overlap and must not be added together.
Strengths
Leading-edge technology mix: +3% to +5% sensitivity. More advanced production can support revenue per wafer and customer retention. Assuming technology mix produces 3–5% more revenue than our base forecast, with unchanged net margin and valuation multiple, modeled value increases by the same proportion. The financial benefit depends on pricing covering the higher manufacturing costs.
Financial flexibility: +2% to +4% sensitivity. Cash generation provides capacity to fund expansion and absorb fluctuations without issuing equity. If that flexibility supports a 23.5–24× earnings multiple rather than our 23× reference, modeled value increases approximately 2–4%. This premium is a judgment, not an automatic consequence of holding cash.
Weaknesses
Ramp-related margin pressure: −2% to −4% sensitivity. New-node production can increase revenue while temporarily reducing profitability. Against an illustrative 50% normalized net margin, a one- to two-percentage-point reduction lowers earnings and value by 2–4%, assuming unchanged revenue and multiple.
HPC concentration: −4% to −9% sensitivity. An increasingly HPC-dependent revenue mix raises exposure to customer investment cycles. Applying a one- to two-turn discount to the 23× reference multiple reduces value approximately 4–9%, even if earnings meet expectations.
Opportunities
Further demand expansion: +5% to +10% sensitivity. Continued leading-edge demand could lift shipments above our forecast. Revenue 5–10% above the base case produces an equivalent increase in value if margins and the multiple remain unchanged. This overlaps with the technology-mix opportunity.
Successful 2nm maturation: +2% to +4% sensitivity. Yield improvements and manufacturing efficiency could improve earnings conversion after the initial ramp. A one- to two-percentage-point improvement above the illustrative 50% net margin raises modeled earnings by 2–4%. This is an alternative to the margin-pressure outcome, not an additional benefit to count alongside it.
Threats
Demand falling short of capacity: −13% to −24% sensitivity. Lower utilization could coincide with rising depreciation. A stress combining revenue 5–10% below forecast, net margins of 48–46%, and multiples of 22–21× produces this range relative to the 50% margin and 23× reference.
Multiple compression: −9% to −17% sensitivity. Even satisfactory business performance may not protect the shares if investors pay less for future earnings. A decline from 23× to 21–19× produces this valuation effect with earnings unchanged.
Taiwan-related disruption: losses are not reliably bounded. A three- to five-turn multiple discount would reduce modeled value approximately 13–22% without changing earnings. However, a blockade, conflict or prolonged production interruption could impair earnings as well. That more severe tail risk cannot responsibly be contained within an ordinary multiple sensitivity.
Valuation Scenarios
Our valuation uses 2027 earnings to estimate a 12-month forward value. It is not a discounted-cash-flow calculation of present intrinsic value.
The model uses only company disclosures as financial inputs. Future growth, margins, valuation multiples and probabilities are our independent assumptions—not management guidance or analyst consensus.
We estimate adjusted 2026 earnings of approximately US$17.14 per ADR, compared with US$16.40 previously. This combines reported nine-month earnings with a Q4 model based on guidance midpoints and removes the previously identified Vanguard gain. It does not remove every potentially unusual item.
Bear Case — Approximately US$305
Revenue grows 5% in 2027, but net margin declines to 45%. Modeled ADR earnings fall to approximately US$16.03.
A 19× multiple produces a value near US$305. We assign a 25% probability.
This scenario reflects slower demand and weaker manufacturing economics. It does not represent a severe geopolitical disruption.
Base Case — Approximately US$465
Revenue grows 22%, while net margin settles at 49%. Modeled ADR earnings reach approximately US$20.27.
A 23× multiple produces a value near US$465. We assign a 50% probability.
This assumes continued leading-edge expansion, but allows for manufacturing costs to constrain profitability.
Bull Case — Approximately US$595
Revenue grows 30%, with net margin reaching 52%. Modeled ADR earnings rise to approximately US$22.93.
A 26× multiple produces a value near US$595. We assign a 25% probability.
This requires sustained demand, strong utilization and effective execution together.
Using unrounded scenario values, the probability-weighted result is approximately US$458, rounded to US$460 per ADR. Scenario headlines are rounded to the nearest US$5.
Verdict
TSMC’s Q3 report strengthens our growth thesis. Advanced-node adoption increased, earnings expanded, and cash conversion improved. The initial 2nm margin cost is visible, but it has not prevented substantial profit growth.
We therefore raise our forward valuation from US$440 to approximately US$460, without increasing the scenario multiples. The upgrade comes from earnings expectations rather than a willingness to pay more for each dollar of profit.
That distinction matters. TSMC can remain an exceptional business while its shares offer an insufficient valuation cushion.
A price of US$368 would represent a 20% discount to the rounded forward estimate. That is an arithmetic threshold—not a guaranteed safe entry point—and a present-value assessment would additionally account for the required investment return.
For growth investors, the central question remains whether demand will persist long enough to generate attractive returns on the capacity being built. Q3 provides stronger evidence of current demand and financing capacity, but it cannot settle that longer-term question.
