Analysts expect TSMC to hit the top of its $44.6-45.8 billion third-quarter range

TSMC's raised target of slightly above 40% revenue growth for the year, in dollar terms ^[9], asks more than its reported quarters have delivered (or rather, more than the two quarters in the preview have delivered). Second-quarter revenue of $40.2 billion was up 33% ^[5], and the third-quarter guide works out to 37% at its midpoint ^[3]. Annual growth is a weighted average of the four quarterly rates. With two of them under 40%, the year clears the target only if the first quarter or the fourth runs faster than 40% ^[3]. Even the consensus figure of $45.8 billion ^[4] implies roughly 39% growth on a prior-year quarter of about $33 billion ^[4]. The preview does not give the first-quarter rate, so the guidance alone cannot say how much of the gap the fourth quarter has to close.

Capex is the figure TSMC sets outright, and it has moved the range up to $60 billion to $64 billion ^[10]. Spread evenly, the $62 billion midpoint is $15.5 billion a quarter, a little over half the roughly $29.8 billion of gross profit implied by the third-quarter midpoints for revenue and margin ^[6]. Spending is lumpy and gross profit is not cash, so the ratio is rough. It still puts about half of what each quarter's wafers earn above cost back into new capacity. Crypto Briefing, which published the preview, argues that a change to the range in either direction could signal how TSMC reads the durability of the AI cycle ^[13].

The print can split three ways for holders of the chip designers. Revenue at or above $45.8 billion with margins inside 65% to 67% ^[6] confirms what analysts already expect. Top-of-range revenue with high-performance computing below its second-quarter share of 66% ^[7] would mean the growth came from TSMC's other segments. A margin under 65% on the same revenue would mean each dollar of sales cost TSMC more to produce than it guided.

I think the high-performance computing share is the line on October 15 ^[1] that tells Nvidia, Broadcom and AMD holders the most. It is the one figure that isolates the category covering data center processors and AI accelerators ^[7], the chips all three rely on TSMC to build in volume ^[8]. The case against is that 66% is a mix ratio. It can fall because other segments grew faster while AI orders held flat, and a lower share would then tell holders little about the three designers. The view is wrong if the share drops while management's commentary on demand into the final quarter ^[14] still supports a year above 40%. In that case the share moved on its denominator, and demand for AI chips did not weaken.
