TSMC Profit Jumps 70% on AI Demand, Margin Outlook Sinks Shares

Taiwan Semiconductor Manufacturing Co. reported a jump of nearly 70% in third-quarter net profit on Thursday, with net profit rising to about NT$763 billion and revenue reaching about $47 billion, above the top of the company's own guidance range. The gross margin of about 66% was well up on a year earlier but down from the second quarter. US-listed shares slipped after the results, as investors focused on softer margin guidance and a heavy spending programme rather than the beat itself.

Context — why TSMC's beat was not enough for the market

TSMC's third-quarter revenue cleared the top of its own guidance range, and net profit came in slightly ahead of analyst estimates compiled by LSEG. That is the strongest form of a beat: not just above consensus, but above the company's own stated ceiling. The share reaction shows how much of that was already priced in.

The comparable the company itself supplies is sequential, not annual. Gross margin of about 66% rose sharply year on year but declined from the second quarter, and TSMC attributed that dip mainly to the early ramp-up of its 2-nanometre production. A new node carries higher initial costs before yields and utilisation mature, so the margin path bends downward before it bends back.

The AI mix is what changed. High-performance computing, the segment that includes AI accelerators, accounted for 68% of revenue, up from 57% a year earlier. The newest 2-nanometre technology made up 8% of wafer revenue, up from 3% in the previous quarter. Those two shifts explain both the profit jump and the margin drag in the same quarter.

Chief Executive C.C. Wei said AI demand remained extremely strong and suggested it would probably outpace the company's earlier long-term growth forecast. He said supply still falls well short of demand, with TSMC building close to 20 new fabs, most of them in Taiwan.

Data — what the numbers show

The headline figures: net profit of about NT$763 billion, revenue of about $47 billion, gross margin of about 66%, high-performance computing at 68% of revenue, and 2-nanometre at 8% of wafer revenue.

Metric	Q3 2026	Prior period
Net profit	~NT$763bn	~70% lower a year earlier
Revenue	~$47bn	Above top of own guidance
Gross margin	~66%	Up y/y, down from Q2
HPC share of revenue	68%	57% a year earlier
2nm share of wafer revenue	8%	3% in prior quarter

For the fourth quarter, TSMC guided revenue of about $52 billion to $54 billion and a gross margin of 65% to 67%, a midpoint slightly below the third quarter. It now expects full-year revenue growth of around 44% in US dollar terms, up from slightly above 40% in July. The company reaffirmed 2026 capital spending of $60 billion to $64 billion and said investment over the next three years would be significantly higher than in the previous three.

Analysis — what it means for markets and sectors

The fourth-quarter margin guide is the crux. A midpoint slightly below the third quarter implies further dilution from the 2-nanometre ramp, and management said overseas factories, including in Arizona and Japan, will weigh more heavily on margins over time. Heavier capital spending points to lower free cash flow in the near term.

That combination is why a beat of this size did not hold the shares. With strong growth already expected, the profit surprise was not large enough to offset concerns about the cost of building capacity. Investors are now trading margins and cash flow, not the top line.

The read-through for the supply chain runs two ways. TSMC's view that demand is running ahead of capacity, and its willingness to keep spending to meet it, is supportive for equipment makers and suppliers across the semiconductor supply chain. Higher planned capital spending is the clearest positive signal for that group.

The counter-argument is that capex at this scale is a claim on future returns, not a guarantee of them. Overseas fabs carry structurally higher costs, and margin dilution from a new node is only temporary if yields mature on schedule. If they do not, the spending programme becomes a drag rather than an investment.

Positioning follows the same split. Taiwan's equity benchmark, where TSMC carries a heavy weighting, is likely to take its lead from how the stock trades in Taipei. The company did not disclose customer-level AI spending plans or order-book terms, so the durability of that demand is not visible in the results.

Outlook — what to watch next

The next tests are whether margins stabilise as 2-nanometre production matures, and whether customers' AI spending plans hold up through next year. TSMC's own fourth-quarter guidance of about $52 billion to $54 billion in revenue and a 65% to 67% gross margin sets the first checkpoint.

Beyond that, the 2026 capital spending range of $60 billion to $64 billion is the number to track against the company's statement that the next three years will run significantly higher than the previous three. Any change to that range would move the equipment supply chain.

On the margin side, watch the trajectory of the 2-nanometre share of wafer revenue against the gross margin line. The node was 3% of wafer revenue in the prior quarter and 8% in the third. If margin holds as that share grows, the dilution thesis weakens.

Frequently Asked Questions

Why did TSMC shares fall despite a 70% profit jump?

The beat was already priced in. Investors focused on fourth-quarter gross margin guidance of 65% to 67%, a midpoint slightly below the third quarter, and on capital spending reaffirmed at $60 billion to $64 billion for 2026. Management also said overseas factories in Arizona and Japan will weigh more heavily on margins over time. Higher spending points to lower near-term free cash flow, which offset the profit surprise.

What does TSMC's 2nm ramp mean for its margins?

TSMC attributed the sequential gross margin decline mainly to the early ramp-up of 2-nanometre production. New nodes carry higher initial costs before yields and utilisation mature. The technology reached 8% of wafer revenue in the third quarter, up from 3% in the previous quarter. As that share grows, the margin line becomes the key indicator of whether dilution is temporary or persistent.

Which parts of the AI supply chain benefit from TSMC's capex plans?

TSMC reaffirmed 2026 capital spending of $60 billion to $64 billion and said investment over the next three years would be significantly higher than the previous three, with close to 20 new fabs under construction, most in Taiwan. Higher planned capital spending is a positive read-through for semiconductor equipment makers and suppliers. The company did not disclose customer-level spending plans or order-book terms.

Bottom Line

TSMC's AI-driven profit beat was not enough to offset margin dilution and a $60 billion-plus capex bill.
