TSMC Q3 Blows Past Guidance — Q4 Sees 58% YoY Jump
TSMC Q3 revenue hit $46.72B, crushing guidance, with Q4 midpoint implying 58% YoY growth. Here's what the numbers mean for chip investors.
Key Points
- TSMC Q3 revenue came in at $46.72B, beating the top of its own $44.6–$45.8B guidance range, with Q4 guidance raised to $52.3–$54.3B — a 58% year-over-year jump at the midpoint.
- The 2nm ramp is the real story: that process node already accounts for 8% of wafer revenue, up from 3% last quarter, with advanced nodes collectively hitting 79% — the infrastructure of every major AI chip in production.
- Watch TSM's November ADR price action against the $52.3B Q4 revenue floor; any macro-driven pullback toward the $195–$200 range on the ADR has historically been a reentry level for momentum traders.
TSMC Q3 revenue landed at $46.72 billion — $900 million clear of the top end of its own guidance range — and the company's Q4 outlook of $52.3–$54.3 billion puts a 58% year-over-year gain on the table. Net income for the quarter was NT$763.06 billion, up 68.7% year-over-year, making it the sixth consecutive record quarter. The market's response was a -2.29% decline in TSM shares Friday, a reaction that says more about sector-wide anxiety than about anything C.C. Wei said on the call.
Inside the Beat
The headline revenue figure matters, but the margin structure is where analysts are doing their real work this morning. Gross margin came in at 66.4%, down 1.3 percentage points sequentially — the modest compression reflects ramp costs tied to 2nm and early CoWoS advanced packaging expansion, not demand softness. Operating margin held at 58.7%, and EPS translated to approximately $4.60 per ADR for the quarter. For a company running a $60–$64 billion capital expenditure program in 2026 alone, those margins are extraordinary.
The revenue mix tells the structural story. High-performance computing — the catch-all that covers AI accelerators from Nvidia, AMD, and Broadcom, as well as Apple's M-series silicon — accounted for 68% of total revenue. Smartphones contributed 21%. Those proportions have been widening in HPC's favor for six consecutive quarters, and nothing in the Q4 guide reverses that. CEO C.C. Wei raised TSMC's full-year 2026 revenue growth outlook to approximately 44% in U.S. dollar terms, a figure that was already above consensus before this call. The SEC 6-K filing confirms the guidance range and the capex reiteration without ambiguity.
The 2nm Inflection and the Wafer War
The number that deserves more attention than it's getting is the 2nm revenue share: 8% of wafer revenue in Q3, up from 3% in Q2. That is a near-tripling in a single quarter of the most advanced commercial semiconductor process on the planet, and TSMC is the only foundry running it at yield levels that matter. Combined with older advanced nodes, processes at 7nm and below now represent 79% of total wafer revenue — the rest of the industry is essentially fighting over legacy capacity.
That capacity scarcity is acute. TSMC North America President Sajiv Dalal has publicly stated he receives at least 10 calls daily from customers seeking wafer allocations. Mizuho's Jordan Klein, speaking to CNBC this week, described the competition among Nvidia, Apple, Broadcom, and AMD as "extremely fierce," and estimated TSMC could push capacity 10%–20% beyond earlier targets — potentially reaching 120,000 wafers per month by year-end. That estimate, if accurate, still does not come close to satisfying current booking demand from the four largest fabless customers simultaneously scaling next-generation products.
The strategic implications cut both ways. For TSMC, scarcity pricing is a feature, not a bug, and the $60–$64 billion capex envelope for 2026 is designed to expand that lead, not merely defend it. For the customers, the capacity crunch creates real execution risk. Nvidia's Blackwell Ultra ramp, AMD's MI400 series, and Broadcom's custom ASIC commitments to Google and Meta are all gated, to varying degrees, by TSMC line time. Any customer that loses allocation priority — even for a quarter — faces product-launch delays and potential revenue misses.
What Traders Watch Next
The Friday -2.29% move in TSM is contextually important. The stock has gained nearly 40% year-to-date in 2026, versus a 60%-plus move in the PHLX Semiconductor Index, meaning TSM has actually underperformed its own sector even as it posted six straight record quarters. That divergence is partly valuation discipline by institutional holders and partly concern about geopolitical risk given Taiwan's proximity to ongoing cross-strait tensions. This week, a separate headline — Taiwan considering tighter AI chip export controls aligned with U.S. restrictions, per Yahoo Finance — added another layer of uncertainty.
Traders who bought TSM on the Q2 earnings beat and are now sitting on gains need to decide how much of the Q4 guide is already priced. The midpoint of $53.3 billion would represent the largest single quarter in TSMC's history by a margin of more than $6.5 billion. If gross margin holds above 65% — which management's comments on CoWoS pricing power suggest is feasible — then Q4 earnings could push ADR EPS toward $5.10–$5.25 for the quarter alone. At the current multiple, that is not stretched. At a multiple that accounts for the DOJ's escalating Nvidia probe or any Taiwan export control tightening, it requires more discipline.
The setup for next week is straightforward: TSM's ADR price in the $195–$200 range, which served as a consolidation zone during the August pullback, is the technical level worth watching if the semiconductor sector selloff deepens. On the upside, a clean break above the $230 level — last tested in late September — would signal institutional re-accumulation ahead of the Q4 print. Meta Platforms reports next week, and any commentary on AI inference infrastructure spending will be read directly as a proxy for TSMC N3 and N2 demand. Goldman Sachs has flagged that Meta, along with four other AI hyperscalers, is expected to collectively push capital expenditure to approximately $1.2 trillion next year. Every dollar of that eventually runs through TSMC's order book.
The full-year 2026 capex of $60–$64 billion is the forward commitment that matters most for long-dated positions. TSMC has never missed a capex target it announced mid-year. That spending — on advanced packaging, on Arizona fab expansion, on 2nm yield improvement — is the moat being built in real time. Traders shorting TSM on geopolitical noise are betting against the only company that can build the chips that power the entire AI stack. That has been a losing trade for six consecutive quarters.
