Key Earnings Metrics

TSMC delivered its sixth straight record quarter, but the headline number was already known from monthly reports. The real focus is on how the 2nm ramp and overseas fab costs are pressing gross margins, and whether Q4 guidance confirms demand is still accelerating.

• Q3 revenue: NT$1,494.2B, up 50.9% YoY (about US$46.71B). That came in roughly 2% above the top of the US$44.6-45.8B range TSMC set in July, showing demand stayed stronger than the company's own forecast.
• September revenue: NT$511.86B, up 54.6% YoY. It dipped 0.6% from August but still beat the high end of analyst expectations by about 5.9%, reflecting sustained AI-related pull.
• Q3 gross margin guide: 65-67%, below Q2's 67.7%. CFO Wendell Huang attributed about 3 to 4 percentage points of Q3 margin dilution to the 2nm ramp, with a 2 to 3 point drag expected over the full year.
• 2026 capex raised to US$60-64B from US$52-56B. Consensus had been around US$58B, so the increase is meaningful and signals TSMC is committing more capital to meet advanced-node and packaging demand.
• 2026 growth target lifted to above 40% in USD terms, from at least 30%. This is the second upward revision and sets a high bar for Q4 and 2027 commentary.
• HPC made up 66% of Q2 2026 revenue, up 20% QoQ; smartphones fell 4%. HPC includes AI accelerators but also other chips, so the 66% share overstates pure AI exposure even as it confirms the structural shift toward compute.

Analysts polled by LSEG expect net profit of NT$741-746 billion, up roughly 64-65% YoY. A profit above about NT$707 billion would mark the highest quarterly profit in TSMC's history and an 11th straight quarter of growth.

Q2 wafer ASP reached US$9,271, up 7.8% QoQ. Pricing power is a critical margin support, and any 2027 price commentary could shift forecasts in either direction.

Management Commentary

CEO C.C. Wei addressed CoWoS capacity directly on the Q2 call, saying it will be a long time before TSMC can meet customer demand. CoWoS is the advanced packaging step that joins processors and memory into a single AI accelerator, and it remains the industry's primary bottleneck.

CFO Wendell Huang quantified the 2nm hit at about 3 to 4 percentage points of Q3 gross margin. The company has also warned that the full-year dilution could run 2 to 3 points, which is why a margin near the top of the 65-67% range matters more than another revenue record.

Two forces are dragging on margins. The first is the cost of ramping 2nm, where initial yields and volume are still climbing. The second is the higher structural cost of fabs outside Taiwan, which TSMC has consistently flagged as a margin headwind.

3nm lines are running above 100% utilisation, which underscores how tight leading-edge capacity remains even before 2nm contributes meaningfully to revenue.

Strategic Implications

The capex increase to US$60-64B for 2026, and Morgan Stanley's projection of US$75-80B for 2027, can be read two ways. Some investors see heavier spending as proof that demand is real and accelerating. Others see it as a cash drain that weighs on free cash flow before the revenue materialises.

TSMC's pricing power helps bridge that gap. A 7.8% QoQ rise in wafer ASP to US$9,271 shows the company can pass higher costs to customers. Any commentary on 2027 pricing will be closely parsed for whether that leverage continues.

The potential second US hub near Dallas, with up to six advanced fabs, could cost more than the US$265 billion already committed to Arizona. TSMC has not confirmed the plan, but analysts expect questions on the call. A larger US footprint would deepen exposure to higher overseas costs while addressing tariff and geopolitical pressure.

The Section 232 tariff of 25% on certain advanced AI chips took effect on 15 January 2026, covering chips such as Nvidia's H200 and AMD's MI325X. Wide exemptions apply, including chips for US data centres, but the tariff adds a policy layer to every capacity decision TSMC makes outside Taiwan.

Terafab, the Texas-based project bringing together Tesla, SpaceX, and xAI with Intel as the first manufacturing partner, adds another dimension. Elon Musk confirmed early talks with TSMC on 3 October. In the near term, Terafab could become a large customer. Over a longer horizon, it could also create a new rival if the project scales its own manufacturing capability.

The OpenAI revenue report on 8 October knocked the Nasdaq down 1.25% and chip stocks down 3.4%. OpenAI's annualised revenue was close to US$50 billion at the end of September, about US$20 billion below earlier circulated figures. Part of the gap is accounting, since OpenAI does not count sales through cloud partners as revenue. Even so, the news revived concerns about circular AI spending between model makers and chipmakers.

UBS takes the other side, citing industry data that still points to robust AI compute demand. The bank expects average hyperscaler cloud revenue growth of 58% in the September quarter, up from 48% in June, while warning that growth and financing worries could cause volatility.

Samsung's preliminary Q3 numbers offer a cautionary parallel. Operating profit jumped almost ninefold, yet shares fell because analysts had trimmed forecasts as the won strengthened. For TSMC, that episode shows how a record can still disappoint when expectations are this elevated.

What to Watch Next

I would watch four things over the next two quarters:

• Q4 revenue guidance. From a US$46.7B Q3 base, growth of 10-15% points to roughly US$51.4-53.7B in Q4. Analysts expect demand for Nvidia's Vera Rubin platform and 2nm chips to drive another climb, so any guide below that range would feed the OpenAI-sparked doubts.
• Gross margin trajectory. Whether Q3 lands near the top or bottom of the 65-67% range will show how fast 2nm yields are improving. A margin at the low end would extend the dilution story into 2027 planning.
• CoWoS capacity commentary. Wei's admission that demand will outstrip supply for a long time is the strongest signal that AI chip bottlenecks persist. Any update on packaging ramp timelines will move Nvidia, AMD, and broad chip-sector sentiment.
• 2027 capex and pricing signals. Morgan Stanley's US$75-80B capex projection sets a high bar. Confirmation of that range, paired with ASP commentary, would tell us whether TSMC expects to keep raising prices or whether volume alone will carry growth.
