TSMC Q3 2026 Earnings Call: AI Demand, Higher Capex and Margin Dilution

TSMC reported third-quarter revenue of $46.7 billion and guided higher for the fourth quarter, while flagging gross margin dilution from its 2 nm ramp and overseas fabs. Management described AI demand as exceeding supply but said it is being prudent on consumer-driven segments heading into 2027.

TSMC (NYSE: TSM) held its third-quarter 2026 earnings call on 15 October 2026. It is in the news because Nasdaq's earnings coverage listed TSM among the companies reporting before the market opened on 15 October 2026 (Nasdaq pre-market earnings report, published 14 October 2026). The company is a bellwether for AI-related chip demand and capital spending.

Key takeaways

  • Third-quarter revenue rose 16.2% sequentially in US dollar terms to $46.7 billion, above the high end of guidance, according to CFO Wendell Huang.
  • Gross margin fell 1.3 percentage points sequentially to 66.4%, mainly because of dilution from the 2 nm ramp. Operating margin was 58.7% and EPS was TWD 29.43.
  • Fourth-quarter revenue guidance is $52.3 billion to $54.3 billion, with gross margin of 65% to 67%.
  • Full-year 2026 revenue growth is now expected at around 44% in US dollar terms. The 2026 capital budget of $60 billion to $64 billion was reiterated.
  • Management described AI demand as "extremely robust" and above supply, but said consumer and price-sensitive segments are under pressure from rising component prices and macroeconomic uncertainty.

Bull case

  • Revenue beat the top of guidance, and management raised its full-year growth expectation to around 44% (Huang and CEO C.C. Wei, prepared remarks).
  • High-performance computing grew 22% quarter on quarter to 68% of revenue. Automotive grew 23% (Huang).
  • Wei said demand is higher than supply and that he had seen no sign of a slowdown. Asked about the earlier AI accelerator growth framework of a mid-to-high 50s percent CAGR from 2024 to 2029, he said the figure "probably will be higher" (Q&A, responding to Citi's Laura Chen).
  • Capacity is being added: a new 3 nm fab in Tainan, volume production of the second Arizona fab from Q3 2027, and N2 capacity expected to more than double in 2027 (Wei).
  • Wei said A14 is expected to be a bigger node than N2, with customer activity already higher than at the same stage of N2 (Q&A, responding to Morgan Stanley's Charlie Chan).
  • Huang said revenue growth is still expected to outpace capex growth, i.e. capital intensity should ease if the company executes well (Q&A, responding to UBS's Sunny Lin).

Bear case

  • Gross margin declined 130 basis points sequentially and is guided down about 40 basis points at the midpoint for Q4, on 2 nm dilution and overseas fabs (Huang).
  • Margin dilution from overseas fabs is expected to be closer to 2% now but to widen to 3%-4% in the next few years as more US fabs ramp (Huang). Analysts from UBS pressed on what drives the wider figure.
  • Wei said the company is being "prudent" in business planning for 2027 because consumer and price-sensitive end markets are challenged.
  • Tool price inflation is real, and tool supply is tight (Huang). Capex for 2026-2028 is expected to be significantly higher than the previous three years.
  • Analysts raised concerns on possible supply-chain bottlenecks (data center power, HBM, advanced packaging, lasers), a possible insourcing shift by an IDM customer, and the later High NA EUV adoption (2030) versus some competitors. Wei said TSMC does not see itself at a disadvantage on High NA.

What management said

  • "We have no intention to leave food on the table for others." (C.C. Wei, prepared remarks)
  • "The demand is higher than the supply." (C.C. Wei, Q&A)
  • "There is no ceiling for TSMC's profitability." (C.C. Wei, Q&A, adding that a dramatic increase will not happen overnight)
  • "The tool price inflation is real." (Wendell Huang, Q&A)

Risks

  • Rising component prices and macroeconomic uncertainty weighing on consumer and price-sensitive segments (Wei).
  • Dilution of gross margin from the 2 nm ramp and from overseas fabs (Huang).
  • Tool price, material and labor cost inflation, and tight tool supply (Huang).
  • Power availability, HBM, advanced packaging and networking component tightness, raised by analysts as possible sources of a supply and demand mismatch. Wei said TSMC has checked US data center build-out and power supply and that the feedback is "so far so good".
  • Competition in advanced packaging and High NA timing, raised by analysts (Wei responded that TSMC stays competitive).
  • Management's comments that a possible Texas expansion and cooperation with a customer on a "Terafab" project are still under discussion with no conclusion (Wei).

Outlook

  • Q4 2026: revenue of $52.3 billion to $54.3 billion (about 14% sequential growth and 58% year on year at the midpoint, at an exchange rate of 31.8 TWD per USD); gross margin 65%-67%; operating margin 56.5%-58.5% (Huang).
  • Full-year 2026 revenue growth of around 44% in US dollar terms; capex budget of $60 billion to $64 billion; 2026-2028 capex significantly above the prior three years (Wei, Huang).
  • Management declined to give capex numbers beyond 2026 ("too early"), a specific capacity growth percentage, or any customer-specific comment, and said the AI accelerator CAGR definition remains narrow and excludes CPUs. It gave no 2027 revenue guidance beyond saying it is being prudent.
