SMIC's $953.2M gross profit is a peak to test, and its own guide implies $862.6M to $946.8M next

SMIC beat its own guide by $64M of revenue and 1.9 margin points. Its fourth-quarter guide still implies gross profit below the third quarter's $953.2M.

SMIC's best quarter of the nine in the series CTOL checked was the third, at $953.2 million of gross profit. Its own guide puts the fourth quarter lower. The shortage in AI-support chips has raised what the company can earn. Higher current earning power is not yet a sustainable earnings base.

The peak line is the third quarter's gross profit. It measures how far that quarter was a peak, not whether earnings are permanent. SMIC's results release gives revenue of $3,190.0 million and a gross margin of 29.9%.

The guide puts fourth-quarter gross profit under the peak line

The release guides fourth-quarter revenue up 4% to 6% and gross margin to 26% to 28%. On CTOL's arithmetic, $3,190.0 million times 1.04 to 1.06 gives revenue of $3,317.6 million to $3,381.4 million. Times 26% at the low end and 28% at the high end, that is $862.6 million to $946.8 million of gross profit. Even the top of the range falls short of $953.2 million.

Put differently, matching the peak line at a 28% margin would need revenue of $3,404 million. That is above the top of the revenue guide. Each point of margin on third-quarter revenue is worth $31.9 million.

SMIC beat its last guide at the same margin range

The strongest case against expecting fourth-quarter gross profit to fall is SMIC's own record of beating its guide. In August SMIC guided the third quarter to revenue up 2% to 4% and a gross margin of 26% to 28%. Actual revenue came in $64 million above the top of that range, and margin 1.9 points above it.

On CTOL's arithmetic, repeat only the margin beat on top-of-range revenue and gross profit is 29.9% of $3,381.4 million, or about $1,011 million.

That is arithmetic possibility, not evidence of likelihood. The guide cannot be read as a ceiling, and the last beat makes another one plausible. Even the bottom of the range, $862.6 million, beats the second quarter's $760.6 million.

Guidance now implies a fall, so holding $953.2 million requires another beat, though a smaller one than the third quarter's would do. The unresolved question is whether SMIC can sustain its new profit base as management expects margins to ease.

Scarcity is lifting prices and utilization

High utilization and better revenue per wafer point to current operating leverage, not necessarily a durable margin premium. Utilization reached 97.3%, from 93.7% in the second quarter. Shipments rose 5.7% and revenue per wafer 1.8%, a blend of price and mix rather than a list price. Operating profit rose 32.9% to $710.1 million.

Management says the tightness sits in AI-support chips. In its August call record, Co-CEO Zhao Haijun cited the logic and BCD parts used in data-center boards. He also cited about 16,000 power-management parts in one 72-GPU rack. He said demand for BCD should stay visible through the end of next year, and that SMIC would not cut prices this year. That visibility is the bullish case for earnings lasting beyond one quarter.

The catch is that the same call says smartphone, auto and industrial markets are in decline. Smartphones fell to 14.3% of wafer revenue while the shortage sits in a few product lines.

Owners' profit of $428.4 million fell 10.6% on the quarter. That is accounting, because the second quarter carried a $275.9 million gain in other income.

Precedent cuts both ways on whether a shortage premium lasts

UMC shows the downside. Its fourth-quarter 2022 results showed a 42.9% gross margin at 90% utilization. A year later its fourth-quarter 2023 results showed 32.4% at 66%. That is gross profit of about NT$29.1 billion falling to about NT$17.8 billion, from revenue of NT$67.84 billion and NT$54.96 billion. UMC shows how falling utilization can reverse a foundry's scarcity premium and sharply compress gross profit. The break is volume: UMC's fall came with a broad inventory correction, while SMIC runs near full.

SK hynix shows the upside. Its FY2025 results put operating profit at KRW 47.2063 trillion, from KRW 23.4673 trillion in FY2024. The company said "the annual revenue increased by more than 30 trillion won while the annual operating profit nearly doubled year-on-year."

Shortage-led profits can persist at SK hynix, but memory pricing is not a direct forecast for SMIC's foundry margins. The break is that SK hynix's fourth-quarter 2025 operating profit was KRW 19.1696 trillion, up 68% on the third quarter, so it shows no peak and fall. It also reports company-wide, not for one AI product line.

Receivables growing far faster than revenue are the second test of scarcity

SMIC's receivables rose to $2,294.8 million from $1,512.8 million, up 51.7% while revenue rose 6.1%. Measured as trade and other receivables against quarterly revenue, that is 66 days against 46 in the second quarter. It is a balance-sheet proxy, not a verified payment period, so the 13 November results call is the first place to ask what changed.

SMIC's fourth-quarter results, which it typically reports in February, set the test. Gross profit at or above $953.2 million would show that SMIC can repeat its peak once, not that the figure is a durable run rate.

A durable run rate would take consecutive quarters at that level. SK hynix's profit kept rising. UMC's fell back with utilization. A result inside the guided $862.6 million to $946.8 million shows how far the third quarter was a peak. Until durability is shown, separate SMIC's stronger current earnings from the profits investors can reasonably expect to persist.
