TSMC Smashes Q3 With Record NT$763bn Profit — Yet Shares Slide as AI Euphoria Cools

Taiwan Semiconductor Manufacturing Company has posted the most profitable quarter in its history — and watched its shares fall anyway. The world's largest contract chipmaker reported on Thursday that third-quarter net profit reached NT$763.1 billion, about US$23.6 billion, according to Reuters — up 68.7% on the year before and the company's eleventh consecutive quarter of profit growth.

Revenue matched the superlatives: up 50.9% year-on-year to a record NT$1.49 trillion. Diluted earnings per share came in at NT$29.43, equivalent to $4.60 per American depositary receipt. And the profit figure sailed past the LSEG SmartEstimate of NT$746.3 billion compiled from 16 analysts, Reuters reported — a clean, unambiguous beat.

Then the market did the opposite of what the numbers suggested. Taipei-listed shares closed Thursday down roughly 2%, while the US-listed ADRs — which had already ended Wednesday's session at $430, down 3.4% — fell a further 4% on Thursday. The selloff was not contained to TSMC: the Philadelphia Semiconductor Index dropped for a seventh straight session as chip stocks slid across the board.

The paradox of a record quarter and a falling share price is the story of this market. With TSMC stock up nearly 60% so far in 2026 and the company valued at about US$2.1 trillion — Asia's most valuable listed business, at nearly double Samsung's market capitalisation — perfection was already priced in. What investors are pricing now is not growth, but the return on it.

The numbers behind the record

The detail beneath the headline figures shows a company operating at full throttle. Gross margin held at 66.4% and operating margin at 58.7% — both above the company's own guidance — even as the costly ramp-up of 2-nanometre production gathered pace, according to Invezz's analysis of TSMC's investor presentation. New process nodes typically depress margins in their early quarters, so holding margins at these levels during a 2nm ramp is a signal of unusual manufacturing discipline.

Advanced nodes — 7 nanometres and below — accounted for 79% of wafer revenue in the quarter. Within that, 2nm's share of wafer revenue more than doubled to 8% from 3% in the second quarter, while 3nm climbed to 33% from 30%. The mix shift tells its own story: customers are moving to the bleeding edge as fast as TSMC can qualify it.

High-performance computing, the platform serving AI accelerators and data-centre silicon, generated 68% of revenue, up from 66% in the second quarter. Smartphones contributed 21%. The AI build-out is no longer merely a growth driver for TSMC — it is now the dominant one.

2nm arrives ahead of the curve

The 2-nanometre ramp deserves its own moment. For a brand-new node to represent 8% of wafer revenue this early in its production life is a fast start by industry standards, and it underlines why TSMC's manufacturing lead is treated as a strategic asset rather than merely a commercial one. Rival foundries remain a full generation behind in volume production.

The timing matters beyond bragging rights. Every major AI accelerator roadmap depends on leading-edge capacity, and TSMC is the only supplier that can deliver 2nm-class silicon at the volumes the hyperscalers are now consuming. That scarcity is the root of both the record margins and the geopolitical attention the company attracts.

Guidance raised, expectations raised higher

Management paired the results with a confident outlook. TSMC guided fourth-quarter revenue to between US$52.3 billion and US$54.3 billion, CoinPaper reported, and lifted its full-year 2026 revenue growth outlook to about 44% in dollar terms, up from its previous expectation of slightly above 40%.

On paper that is a meaningful upgrade — four extra percentage points of growth on a base already running at record revenue. In practice, it landed in a market that has stopped rewarding beats and started asking harder questions. When a company guiding to 44% annual growth still sees its shares sold, the message from investors is blunt: show us the returns, not just the growth.

The market's mood: from growth to returns

This is the regime change running through chip stocks this week. After two years in which any whiff of AI exposure was enough to lift valuations, investors have begun interrogating the return on the hundreds of billions being poured into data centres. A seventh consecutive down day for the Philadelphia Semiconductor Index suggests the scepticism is sector-wide, not TSMC-specific.

The scale of the selloff deserves proportion. A 2% fall in Taipei and a 4% slide in the ADRs barely dents a stock that has risen almost 60% this year. But direction matters: for the first time in this cycle, a flawless quarter was treated as an excuse to take profits rather than a reason to add.

The US$265 billion American bet

Part of what investors are now scrutinising is where the money is going. TSMC expects to spend between US$60 billion and US$64 billion on capital expenditure this year — a sum that would comfortably swallow the annual revenues of most Fortune 500 companies — and it has committed US$265 billion to its Arizona fabrication complex, including a US$100 billion expansion announced in July. The company is also reportedly weighing a further investment in Texas.

The Arizona commitment makes TSMC the single largest foreign direct investor in US semiconductor manufacturing, and it answers the supply-chain diversification demands that have become a condition of doing business with Washington. Whether it earns its cost of capital is a question that will be asked of these fabs for the next decade — which is precisely the question the stock is asking today.

A crowded week in chips

TSMC was not the only Asian chipmaker making headlines. Samsung reported a nearly nine-fold jump in third-quarter profit on surging AI memory demand, underscoring that the memory cycle has turned decisively in favour of high-bandwidth memory for AI systems. SK Hynix, meanwhile, made its planned US NAND factory conditional on Washington approving export licences for chipmaking equipment destined for China — a reminder that in semiconductors, geopolitics is never far from the factory floor.

Taken together, the week's reports describe an industry where demand has rarely been stronger and politics have rarely been more complicated. The demand side is now established fact; the contested question is how the profits get divided.

What it means for the AI trade

The AI trade is not broken — TSMC's order book says as much. But it is maturing, and maturing trades are judged by cash returns rather than growth rates. The company that prints the industry's most advanced silicon just reported its best quarter ever and was rewarded with a selloff. That is the market's way of saying the easy phase of the AI rally is over, and the proving phase has begun.

For investors, the signal is clear enough: execution still matters more than narrative, but narrative alone no longer suffices. You can track how chip and AI-linked stocks are responding on our markets page.

FAQs

What exactly did TSMC report?

TSMC reported third-quarter net profit of NT$763.1 billion, about US$23.6 billion, according to Reuters — up 68.7% year-on-year and a company record. Revenue rose 50.9% to a record NT$1.49 trillion, diluted EPS reached NT$29.43 ($4.60 per ADR), and the profit figure beat the LSEG SmartEstimate of NT$746.3 billion compiled from 16 analysts. It was the company's eleventh straight quarter of profit growth.

Why did TSMC's shares fall despite a record quarter?

Expectations were doing the heavy lifting: with the stock up nearly 60% in 2026 and a market capitalisation of about US$2.1 trillion — almost double Samsung's — a flawless quarter was already priced in. Investors used the results to take profits and shifted their focus from growth to the return on AI spending, a mood reflected in the Philadelphia Semiconductor Index falling for a seventh straight session. In short, the quarter was judged against a perfect bar it could not quite clear.

What does the fourth-quarter guidance imply?

TSMC guided fourth-quarter revenue to US$52.3–54.3 billion, CoinPaper reported, and raised its full-year 2026 revenue growth outlook to about 44% in dollar terms from slightly above 40%. That implies management sees no let-up in AI-driven demand through year-end, with high-performance computing — already 68% of revenue — continuing to carry the business. The raised bar also leaves less room for future upside surprises.

Why is the 2nm ramp such a big deal?

TSMC's 2-nanometre process reached 8% of wafer revenue in the quarter, up from 3% in the second quarter — an unusually fast start for a brand-new node. New nodes normally weigh on margins during ramp-up, yet TSMC held gross margin at 66.4%, above guidance. The speed of the ramp cements TSMC's technology lead at a moment when every AI accelerator roadmap depends on leading-edge capacity only it can supply at scale.

What is happening with TSMC's US expansion?

TSMC plans US$60–64 billion in capital expenditure this year and has committed US$265 billion to its Arizona fabrication complex, including a US$100 billion addition announced in July. It is also reportedly weighing an investment in Texas. The build-out diversifies production beyond Taiwan and satisfies Washington's reshoring demands — but it is also exactly the kind of spending investors are now interrogating for returns.
