TSMC posted third-quarter 2026 consolidated revenue of NT$1.494244 trillion (approximately $46.8 billion), the foundry's highest quarterly figure on record and a 50.94% increase from a year earlier.

The company reported September 2026 revenue of NT$511.857 billion (approximately $16.0 billion) on October 8, down 0.6% from August but up 54.6% year-over-year. September marked the second-highest monthly revenue in TSMC's history and the second consecutive month above NT$500 billion.

The Q3 result exceeded the upper bound of TSMC's own guidance, set at the second-quarter earnings call between $44.6 billion and $45.8 billion. Sell-side analysts had also underestimated the magnitude: consensus expected September revenue between NT$444.8 billion (approximately $13.9 billion) and NT$483.2 billion (approximately $15.1 billion), with a roughly 9.9% month-over-month decline. TSMC's actual month-over-month drop was just 0.6%.

What does the Q3 beat tell us about AI demand?

The shortfall in analyst forecasts reflects misjudged shipment momentum for advanced process nodes. Using the midpoint of TSMC's US-dollar guidance, quarter-over-quarter growth would have come in near 12% and year-over-year near 37%. Actual New Taiwan dollar revenue grew 55.81% quarter-over-quarter and 50.94% year-over-year, pointing to AI-driven orders as the primary growth driver.

Cumulative revenue for the first nine months of 2026 reached NT$3.898727 trillion (approximately $122.2 billion), up 41.1% from the same period a year earlier and a record for the year-to-date window.

How are analysts revising capex expectations?

US-based sell-side analysts responded to the Q3 beat by raising TSMC's capex outlook. The 2027 estimate moved from $78 billion to $85 billion, and the 2028 figure climbed from $82 billion to $98 billion. The same group projects US dollar revenue growth of 42% in 2026 and 36.9% in 2027, with gross margins reaching 67.2% and 67.5%, respectively.

TSMC had previously guided Q3 gross margin to 65–67% and operating margin to 56–58%; actual profitability will be disclosed at the October 15 earnings call.

What will TSMC address on October 15?

TSMC entered its pre-earnings quiet period on October 5, which runs through October 14. Five topics will draw scrutiny at the October 15 call, according to industry sources:

• AI growth momentum and visibility
• Advanced process and advanced packaging capacity expansion
• 2027 capital expenditure planning
• Overseas fab progress, including the Texas project
• Potential foundry price increases for next year

How is the market reacting?

TSMC shares closed down NT$35, or 1.35%, at NT$2,550 on October 8, with intraday lows near NT$2,560. Analysts attributed the pullback to cautious positioning ahead of the revenue release rather than fundamentals.

The stock's near-term direction will hinge on the full-year outlook and capacity plan disclosed next week, but the September print and the upward capex revisions indicate customer competition for advanced process capacity is running hotter than brokerages had modeled.
