Taiwan Semiconductor Manufacturing Company Limited (TSM)

4Q25 revenue US$33.73B, gross margin 62.3%, 2026 revenue outlook close to +30% in USD

The quarter did more than beat guidance. It showed that leading-edge demand, mix and factory execution are compounding fast enough to offset a rising cost base, so investors now need to underwrite durability of returns rather than demand credibility.

4Q25 says AI-led leading-edge demand is strong enough to reset TSMC's earnings base, and the debate has shifted to how much of that upside survives the N2 and overseas build-out

The earnings base moved higher because advanced-node demand kept compounding through 2025 instead of fading after a strong first half

Revenue US$25.53B -> 30.07B -> 33.10B -> 33.73B across 2025

Revenue kept stair-stepping higher through the year, which is inconsistent with a short restocking pop and much more consistent with structural compute demand landing in TSMC's leading-edge nodes.

Advanced-node mix kept rising, which is why revenue growth translated into a richer earnings mix rather than just more wafer volume

3nm share 22% -> 24% -> 23% -> 28%; advanced nodes 73% -> 74% -> 74% -> 77% of wafer revenue

The company is selling a larger share of wafers at the part of the stack where performance, power efficiency and customer dependence are highest, so each incremental dollar is economically better than in a mature-node recovery.

The N3 family is already behaving like a durable earnings platform, not a one-wave smartphone node

3nm reached 24% of full-year 2025 wafer revenue

Management said newer nodes are sustaining high revenue deeper into their life because customers keep coming in multiple waves, which extends the monetization window on expensive leading-edge capacity.

4Q25 says AI-led leading-edge demand is strong enough to reset TSMC's earnings base, and the debate has shifted to how much of that upside survives the N2 and overseas build-out

Editorial Outline

Branch 1

The earnings base moved higher because advanced-node demand kept compounding through 2025 instead of fading after a strong first half

Revenue US$25.53B -> 30.07B -> 33.10B -> 33.73B across 2025

Revenue kept stair-stepping higher through the year, which is inconsistent with a short restocking pop and mu…

Branch 2

Margin quality improved because utilization and factory productivity overwhelmed the usual foundry leakages

Gross margin 58.8% -> 58.6% -> 59.5% -> 62.3%; operating margin hit 54.0% in 4Q25

The important quality signal is that margin upside came from controllable operating levers and mix, not from…

Branch 3

The upside is no longer demand credibility; it is whether TSMC can carry a much heavier capital and geographic load without breaking the through-cycle margin model

2026 capex US$52B-56B; overseas fabs dilute gross margin 2%-3% early and 3%-4% later; N2 adds another 2%-3% 2026 dilution

TSMC is deliberately moving into a more expensive operating model. The stock now needs proof that technology…

HPC stayed at the center of gravity, which matters because AI is now large enough to influence the corporate P&L rather than sit in optionality

HPC was 55% of 4Q25 revenue; AI accelerators were high-teens % of 2025 revenue

TSMC is no longer relying on a generalized semiconductor recovery. The company is leaning on the part of demand where performance-per-watt…

The company is already guiding into another year of abnormal growth, which means the backlog is deeper than a simple one-quarter beat

1Q26 revenue guide US$34.6B-35.8B; 2026 revenue outlook close to +30% in USD

This is unusual for a foundry. TSMC is signaling that demand visibility reaches beyond the normal quarter-to-quarter handoff, which is why…

Margin quality improved because utilization and factory productivity overwhelmed the usual foundry leakages

Gross margin 58.8% -> 58.6% -> 59.5% -> 62.3%; operating margin hit 54.0% in 4Q25

The important quality signal is that margin upside came from controllable operating levers and mix, not from accounting noise or a one-off pricing squeeze.

The 4Q25 gross-margin beat was mostly self-help

Actual gross margin beat the top end of guidance by 130 bps

Management attributed the beat to better-than-expected cost improvement, favorable FX and higher utilization, which means the quarter valid…

Pricing helps preserve economics, but it is not the main source of surplus profitability

Management said pricing benefits mostly covered inflation in tools, materials and labor

That matters because it suggests TSMC's margin strength is still rooted in utilization discipline and manufacturing excellence, which are m…

Operating leverage is still widening the gap between revenue growth and opex growth even with a larger global footprint

Opex was 8.4% of revenue in 4Q25 vs 8.9% in 3Q25; operating margin rose to 54.0%

Expenses barely moved while revenue stepped up, so scale benefits are still visible despite the company carrying more R&D and a broader man…

Risk

The upside is no longer demand credibility; it is whether TSMC can carry a much heavier capital and geographic load without breaking the through-cycle margin model

2026 capex US$52B-56B; overseas fabs dilute gross margin 2%-3% early and 3%-4% later; N2 adds another 2%-3% 2026 dilution

TSMC is deliberately moving into a more expensive operating model. The stock now needs proof that technology leadership and factory productivity can outrun the cost of globalizing the footprint and launching a new node.

Overseas fabs are strategically necessary because customers want geography, but they are a visible drag on the income statement

Overseas dilution expected at 2%-3% in early stages and 3%-4% in later stages

Arizona and other offshore fabs strengthen customer relevance and geopolitical resilience, but they structurally raise the cost base before…

N2 should deepen the moat, but it starts as a margin headwind before it becomes the next profit engine

N2 entered HVM in 4Q25 with good yield; 2026 N2 dilution expected at 2%-3%

A fast N2 ramp reinforces TSMC's technology lead and demand visibility, yet new nodes always hit margins before learning-curve benefits and…

Non-AI consumer demand is still the main portfolio weak spot

Management flagged tariffs and rising component costs as risks for consumer and price-sensitive segments

TSMC does not need a broad consumer boom to grow, but a renewed consumer slowdown would weaken the parts of the mix that help diversify the…
