TSMC Q3 Revenue Jumps 51%, Beats Estimates as AI Chip Demand Supports Record Sales

Key Takeaways

• TSMC’s monthly disclosures imply third-quarter revenue of approximately NT$1.494 trillion, up 50.9% year on year and around 2.3% above the NT$1.46 trillion market estimate.
• September revenue increased 54.6% from a year earlier, although sales slipped 0.6% from August.
• The October 15 earnings report will provide the next assessment of profitability, advanced chip demand and fourth-quarter expectations.

TSMC Revenue Beat Shifts Attention to Earnings

source: investor.tsmc.com

TSMC’s third-quarter revenue reached approximately NT$1.494 trillion, exceeding market expectations and extending the chipmaker’s strong sales performance ahead of its full earnings release. The result strengthens the evidence of sustained demand across its manufacturing business, while leaving profitability and the outlook for future orders as the next major questions.

Adding the company’s July, August and September revenue disclosures produces quarterly sales of NT$1,494.243 billion. Compared with NT$989.92 billion in the third quarter of 2025, that represents growth of approximately 50.9%. These calculations use revenue denominated in New Taiwan dollars; growth measured in US dollars can differ because of exchange-rate movements.

The quarterly total was approximately NT$34.24 billion, or 2.3%, above the NT$1.46 trillion LSEG SmartEstimate compiled from 19 analysts. The revenue beat provides an early indication of business momentum, but it does not establish whether earnings or margins also exceeded expectations.

September Sales Remain Near August’s Record

TSMC reported September consolidated revenue of NT$511.857 billion on October 8. Sales rose 54.6% from September 2025 but declined 0.6% from the previous month. Revenue for January through September reached approximately NT$3.899 trillion, an increase of 41.1% from the same period last year.

The slight monthly decline followed August revenue of NT$514.806 billion. July sales were NT$467.580 billion, meaning the quarter’s final two months both generated more than NT$510 billion.

That pattern matters when interpreting September’s results. A small decline from a strong preceding month does not, by itself, establish a deterioration in demand. The quarterly total gives a broader view than a single monthly comparison.

However, monthly revenue figures reveal only part of the operating picture. They do not identify how much growth came from shipment volumes, pricing, changes in the product mix or currency effects. The earnings release should provide more detail on the sources of the increase.

AI Demand Supports the Growth Story

TSMC manufactures chips for customers including Nvidia and Apple, placing the company at the intersection of AI infrastructure investment and consumer electronics demand. Its revenue performance therefore offers a useful indication of manufacturing activity across several important technology markets.

The latest growth is consistent with the strength management described earlier in the year. In July, TSMC said its third-quarter business would benefit from continued demand for leading-edge manufacturing technologies, including the expansion of its 2-nanometer process.

For market participants, the next distinction is between demand already converted into revenue and orders that could support future quarters. Strong sales confirm activity during July through September. They do not independently establish how quickly customers will increase spending in 2027.

The revenue announcement also did not provide a customer-level breakdown. It would therefore be premature to assign a specific share of the quarterly increase to Nvidia, Apple or any individual AI platform.

Revenue Exceeds the Level Implied by Guidance

TSMC previously guided for third-quarter revenue of US$44.6 billion to US$45.8 billion, using an exchange-rate assumption of NT$32 per US dollar.

At that assumed exchange rate, the upper end of guidance corresponds to NT$1.4656 trillion. The calculated quarterly revenue of NT$1.494243 trillion was approximately 2% above that level.

This comparison supports the conclusion that sales exceeded the amount implied by management’s guidance. However, converting the quarterly total at the guidance exchange rate does not produce the company’s final reported US-dollar revenue. That figure should be confirmed in the earnings release.

Keeping the currencies separate also avoids overstating the result. The approximately 51% annual increase refers to revenue measured in New Taiwan dollars, rather than a confirmed US-dollar growth rate.

Profit Margins Will Determine the Quality of the Beat

TSMC’s earlier third-quarter guidance placed gross margin between 65% and 67%, with operating margin between 56% and 58%. Those ranges remain guidance, rather than reported third-quarter results.

The company reported a second-quarter gross margin of 67.7% and an operating margin of 60.3%, providing a reference point for the upcoming results.

Higher revenue can support profitability when production facilities operate efficiently. Nevertheless, manufacturing costs, technology investment and the mix of chips produced can influence how much additional sales translate into operating profit.

The LSEG SmartEstimate places third-quarter net profit at approximately NT$740.8 billion, implying annual growth of around 64%. That remains an analyst estimate until TSMC publishes its earnings.

The distinction is important: the revenue beat is measurable from monthly disclosures, while the expected profit increase still requires confirmation.
