TSMC ($TSM) reports third-quarter results on Thursday 15 October, with the call at 2:00 am ET (7:00 am UK). No other chip stock sits as close to the centre of the AI trade. It makes the processors that Nvidia, AMD, Broadcom and Apple design, so what it says about demand, capacity and margins is read across the whole sector. The unusual part this quarter: the headline revenue number is already known. The question is what management says next.
The setup: revenue is a known quantity
TSMC publishes monthly sales, so the top line has already landed.
- Q3 revenue came in at a record NT$1.49 trillion (about US$46.7 billion), up roughly 51% year on year in Taiwan dollars.
- TSMC’s own July guidance was US$44.6–45.8 billion, so the result beat the top of the range by around 2%.
- September revenue of NT$511.9 billion was the second month in a row above NT$500 billion.
- Nine-month revenue is up about 41% year on year.
That means a revenue beat is not the story. The more important test is whether management delivers a convincing outlook and raises expectations again.
What the Street is looking for
The document’s Q3 guidance, approximate consensus and Q2 comparisons are:
- Revenue: Q3 guidance $44.6–45.8 billion; already reported at about $46.7 billion; Q2 actual $40.2 billion.
- Gross margin: Q3 guidance 65–67%; consensus about 66.5%; Q2 actual 67.7%.
- Operating margin: Q3 guidance 56–58%; consensus about 57.1%; Q2 actual 60.3%.
- EPS per ADR: no Q3 guidance; consensus about $4.39–4.45; Q2 actual $4.31.
Consensus figures vary by provider. Treat them as approximate. Analysts expect Q3 net profit around NT$740.8 billion, up about 64% year on year and a sixth straight record.
An EPS sanity check, not a forecast
The NT$740.8 billion profit figure implies a net margin of roughly 50%, versus 55.6% last quarter. If TSMC lands inside its guided 56–58% operating margin and the usual gap between operating and net margin holds, the document’s illustrative arithmetic puts net profit nearer NT$780 billion, or about $4.70 per ADR.
Consensus may be stale or may be pricing in non-operating items we cannot see. Treat this calculation as a reason to look closely at the EPS line, not as a prediction or an alternative consensus estimate.
Five things that will move the stock
1. Q4 guidance. Analysts cited by Taiwan media expect further growth in Q4, driven by Nvidia’s Vera Rubin platform and TSMC’s 2nm ramp. Because Q3 already beat guidance, the market will want a Q4 range that clears that higher base.
2. Full-year growth. In July, TSMC lifted 2026 growth to slightly above 40% in US dollars, from above 30%. With nine months banked at +41%, a further raise is the natural test. The nine-month figure above is in Taiwan dollars, so the currency bases should not be treated as identical.
3. The 2nm margin hit. Management said the 2nm ramp would dilute gross margin by 3 to 4 percentage points in the second half, and that overseas fabs add a further 2 to 3 points of drag initially. The guided 65–67% range already absorbs this. Watch whether gross margin lands at the top of that range and what the Q4 margin guide says.
4. Capex and 2027. 2026 capex guidance was lifted to $60–64 billion from $52–56 billion. One broker, GF Securities, has pencilled in around $73 billion for 2027. Higher capex is a positive for equipment makers and a margin question for TSMC itself.
5. Pricing and geography. Investors are also listening for any signal on price increases next year and for updates on overseas expansion, including whether a Texas facility is on the table.
What the market is pricing in
The source document records TSM closing around $453 on 9 October, a market cap of roughly $2 trillion. The stock was up about 50% year to date, but the iShares Semiconductor ETF (SOXX) was up more than 80%, so TSMC had lagged its own sector. These are dated, end-of-day figures, not current quotes.
Options were pricing a move of about ±6.1% as of 1 October. That snapshot is not a current implied-move estimate. After the July beat, the stock still closed 2.3% lower. With expectations this high, good is not always enough.
What TSMC’s print tells us about the rest of semis
TSMC sits in the middle of the supply chain, so its numbers cross-check what everyone else has been saying. The following peer figures and signals are reproduced from the supplied preview as of 14 October 2026.
ASML ($ASML), reported 14 October: Q3 sales €11.7 billion and gross margin 57.5%; guided Q4 to €14.2–15.2 billion and full year to €44–45 billion. Equipment orders are a lead indicator for fab spending. A big Q4 guide says TSMC and memory makers are buying tools; TSMC’s capex number is the confirmation.
Nvidia (Nvidia): Q2 FY27 revenue $96.2 billion; guided Q3 to $108 billion; Vera Rubin about 20% of data centre revenue in Q3. Nvidia is TSMC’s biggest growth driver. Strong 2nm and advanced packaging commentary supports Nvidia’s ramp. Any capacity constraint would be the risk.
Broadcom (Broadcom) and AMD (AMD): Broadcom reported strong AI semiconductor growth and raised its AI outlook. Custom accelerators are also built at TSMC. Higher HPC demand would support the view that the custom-silicon trend is additive, not simply a substitute.
Micron (Micron): fiscal Q4 revenue $54.2 billion; guided Q1 FY27 to $61.5 billion; HBM largely contracted for 2027. Memory is the part of the chip trade growing fastest in the source’s analysis. TSMC’s advanced packaging commentary links logic and HBM.
Apple (Apple) and handset chips: smartphones were 22% of Q2 revenue and fell 4% sequentially. Q3 benefited from inventory build ahead of new phone launches. Watch whether handsets drag in Q4.
Intel (Intel) and Samsung foundry: competitors for leading-edge capacity. TSMC’s roughly 70% foundry share means any price rise or capacity sell-out is a tailwind for the wider ecosystem and a pressure point for rivals trying to win share.
How to read the possible outcomes
- Beat and raise, with margins at the top of the range: supportive for Nvidia, Broadcom, AMD and equipment names including ASML, Applied Materials (Applied Materials), Lam Research ($LRCX) and KLA (KLA). It reinforces the idea that the AI build-out is still supply-constrained, not demand-constrained.
- In line, with a cautious tone on 2nm costs or 2027 capex: a possible sell-the-news reaction for TSM itself, but potentially less damaging for design houses, which benefit from TSMC adding capacity.
- Soft Q4 guidance or a hint of hyperscaler digestion: a risk to the whole sector. The source cites a 43-times earnings valuation for SOXX, leaving little room for an AI spending wobble.
These are scenarios, not predictions of the result or the share-price response.
Risks to keep in view
- Valuation and positioning: the sector has rallied strongly into the print.
- Geopolitics: Taiwan risk, US-China trade policy and export controls, including the recent HBM export rules cited in the preview, remain swing factors.
- Customer concentration: a small group of hyperscalers and accelerator vendors drives most of the growth.
- Margin mix: 2nm and overseas fabs are structurally dilutive before they scale.
The bottom line
TSMC enters the report with the revenue already in the bag. The share price will turn on three things: the Q4 guide, whether full-year growth is raised again, and how management frames 2027 capex and pricing. Because the company is a read-across for the whole AI hardware chain, the same numbers will shape how Nvidia, ASML, Micron and others trade over the following days.
