VALUFOURWhy Is TSMC’s Margin Falling Despite Booming AI Demand?
TSMC reported strong AI-related demand and higher sales, while N2 ramp-up costs weighed on margins. We examine operating performance, non-operating gains and cash flow after investment.

3% in prior quarter · wafer revenue basis
Sales rose sharply, while margins declined from the previous quarter. The figures need to be read alongside the costs of expanding production and the effect of a prior-quarter non-operating gain. The margin decline discussed here is sequential: both gross margin and operating margin were higher than a year earlier. [4]
AI demand translated into reported growth
Consolidated revenue reached $46.72B, up 41.2% year over year in US dollar terms. HPC revenue grew 22% from the previous quarter and accounted for 68% of consolidated revenue. These results are consistent with management’s description of strong demand for advanced process technologies. HPC includes uses beyond AI, so the 68% figure is not a measure of AI revenue alone. [4]
Processes at 7nm and below accounted for 79% of wafer revenue, including 8% from N2 and 33% from N3. These figures describe wafer revenue, rather than total consolidated revenue. They show the importance of advanced nodes, but do not establish how much individual process selling prices changed. [4]
Why did the N2 ramp dilute margins?
N2’s wafer-revenue share rose from 3% to 8%, while gross margin fell from 67.7% to 66.4%. TSMC identified initial N2 ramp costs as the main source of dilution. A new process can contribute more revenue while its early production costs still weigh on profitability. [4]
CFO Wendell Huang said the rapid N2 ramp-up and overseas fabs were expected to weigh on fourth-quarter gross margin. The company’s gross-margin guidance was 65–67%. For investors, the key issue is whether production becomes more efficient as capacity expands; higher revenue alone does not ensure a higher margin. [5]
N2 is a share of wafer revenue; margins use consolidated revenue. These percentages have different denominators and should not be added together. [4]
What explains the lower net profit margin?
Operating income increased 14.3% sequentially to NT$876.445B, while net income attributable to parent shareholders rose 8.0% to NT$763.064B. Operating margin of 58.7% was lower sequentially but 8.1 percentage points higher year over year. A lower margin does not mean lower absolute operating profit. [4]
Net profit margin fell from 55.6% to 51.1%. Non-operating gains declined from NT$95.83B to NT$34.59B. TSMC attributed that decline mainly to the absence of gains from the disposal and revaluation of VIS shares recognized in the previous quarter. This affects the net-profit comparison and should be assessed separately from N2’s effect on operating margins. [4]
Cash flow improved, but investment continues
Operating cash flow was NT$919.77B, against NT$443.21B of cash CapEx. Company-reported free cash flow, defined as the difference, reached NT$476.56B, up from NT$287.36B. Higher operating cash inflow and lower quarterly investment spending both contributed. [3] [5]
A single quarter of lower spending does not show that TSMC is scaling back its long-term investment plans. The CFO maintained the $60B–64B capital budget for 2026. Investors should consider the timing of quarterly spending alongside the continuing cost of adding production capacity. [5]
Company-reported FCF equals operating cash flow less cash CapEx. Lower quarterly spending does not establish a reduction in the annual capital budget. [3]
What should investors watch next?
Management forecast $52.3B–54.3B in fourth-quarter revenue and around 44% full-year revenue growth in US dollar terms. These figures are guidance, rather than reported results. CEO C.C. Wei also outlined plans to expand N2 capacity and invest in new N3 and overseas fabs. Meeting demand requires those investments to become productive capacity. [5]
The long-term investment case depends on AI demand supporting sustained demand for N2, N3 and advanced packaging. Watch the durability of that demand, initial production costs, overseas fab costs and free cash flow after capital spending. The key test is whether strong sales growth translates into stable margins and cash generation. That outcome is not assured. [5]
Detailed financial data & accounting basis
Reporting period: July 1–September 30, 2026. Quarterly consolidated results under TIFRS. Revenue growth uses USD and differs from NTD growth. N2 shares use wafer revenue. Margin and mix changes are in percentage points; financial growth rates are percentages.
