On July 16 Taiwan Semiconductor Manufacturing Company reported the most profitable quarter in its history, raised its full-year revenue outlook, and watched its shares finish the week 8% lower. The results were not the problem. Revenue of $40.2 billion came in at the top of the guided range, up 33.7% year over year; gross margin of 67.7% cleared the 67.5% ceiling management had set three months earlier; net income rose 77.4% against the prior year ; and Chairman C.C. Wei lifted the 2026 growth target to slightly above 40% in dollar terms . Earnings of $4.31 per American depositary receipt beat the consensus $3.87 by 11.4%, the seventh beat in eight quarters .
What the market chose to price was the capital budget. The 2026 plan went to $60–64 billion, after $52–56 billion in January and roughly $56 billion indicated in April, and third-quarter gross margin was guided down 1.7 percentage points to a 66% midpoint as the 2-nanometer node ramps . The ADR closed the following week at $398.37 from $434.11 the week before, and ten weeks later trades around $443.25 — still 7.5% below the $479.00 high set in early July .
That reaction was a verdict on return on capital, and it is the wrong verdict. The demand behind the spending is better underwritten by customer cash than the market credits; the pricing power funding it is visible in the guide rather than merely asserted on the call; and the capital vintage now going into the ground is earning, on conservative treatment, something between twenty and forty cents of after-tax earnings per dollar committed, against a cost of capital in the low teens.
What TSMC sells, and why 72.5% is not a typo
TSMC builds nobody's chips but its customers'. It is the original pure-play foundry, founded in 1987, and in 2025 it ran 305 distinct process technologies to make 12,682 products for 534 customers . Wafer fabrication was roughly 86% of 2025 revenue; the balance is packaging and testing, mask making, design services and royalties . The scale gap in leading-edge logic is the business model: TrendForce puts TSMC at 72.5% of the top ten foundries' second-quarter revenue, against Samsung Foundry second at 5.9% on $3.26 billion — and in a quarter when that combined top-ten revenue grew 11.5% sequentially, Samsung grew 1.8% .
The mix inside TSMC's revenue has shifted decisively. High-performance...
