Silicon Motion Q3 sales rise 131% as SSD controllers speed up and eMMC and UFS sales fall, implying a revenue beat of about 5.7%

Silicon Motion Technology (SIMO) posted its third-quarter 2026 results at 6:00 PM ET on Wednesday, Oct 28, 2026, after the regular session had closed. Sales rose 24% from the prior quarter and 131% from a year earlier (wire). This was the second quarter in a row of year-over-year growth above 125%. For the quarter ended June 30, 2026, the company had reported sales up 127% year over year.

The breakdown by product shows a shift. SSD controller sales rose 20% to 25% from the prior quarter. eMMC and UFS controllers, which go into phones and other embedded devices, fell 10% to 15% over the same period. In the second quarter, the embedded line had been one of the main growth drivers. Since the release came out after hours, the first full trading session on the numbers is Thursday, Oct 29. The earnings call is at 8:00 AM ET that day.

The numbers against guidance and consensus

The quarter is best measured against what the company forecast on July 29, 2026. At that time, management guided Q3 revenue to $519 million to $541 million, which was 15% to 20% above Q2's $451 million. It also guided gross margin to 50% to 51% and operating profit (EBIT) to about $142.7 million to $154.2 million, according to a Reuters-sourced earnings preview. Analysts went into the print expecting EPS of $3.33 and revenue of $529.1 million, per a GuruFocus preview.

The wire excerpt gives growth rates, not a dollar revenue figure. Applying the 24% sequential gain to Q2's $451 million gives about $559 million. Because the 24% figure is rounded, the true number could fall anywhere from about $557 million to $562 million. As a cross-check, the 118.6% year-over-year growth built into the $529.1 million consensus implies Q3 2025 revenue of about $242 million. Growth of 131% on that base also comes to about $559 million.

Metric	Q2 2026 (reported Jul 2026)	Q3 2026 guidance / consensus	Q3 2026 (Oct 28 release)
Revenue	$451 million	$519M to $541M guide; $529.1M consensus	About $559M implied (+24% Q/Q)
Revenue growth, Y/Y	+127%	+118.6% implied by consensus	+131%
SSD controllers, Q/Q	+5% to 10%	n/a	+20% to 25%
SSD controllers, Y/Y	+50% to 55%	n/a	+55% to 60%
eMMC + UFS, Q/Q	Growth driver	n/a	-10% to -15%
Gross margin	50.2%	50% to 51%	Not in wire excerpt

The excerpt also leaves out gross margin and EPS. Those two lines matter most for judging the quarter's quality. The 50% to 51% gross margin guide is the benchmark. Q2's 50.2% had already come in above the company's own range.

A mix shift toward SSD controllers

The headline growth rate hides a change in what drove it. In Q2, management credited embedded eMMC and UFS, enterprise and edge SSD controllers, and Ferri storage products for automotive and enterprise boot drives. Ferri and boot drive products were close to 30% of revenue in Q2, according to a Q2 call summary. For Q3, the company had said it expected growth across nearly all segments, "led by Ferri for automotive, enterprise boot drive solutions, and our new MonTitan enterprise SSD controllers," according to the Q2 call transcript.

The Q3 numbers fit that forecast in part. SSD controllers sped up from 5% to 10% sequential growth to 20% to 25%, and their year-over-year growth rose to 55% to 60%. The embedded line went the other way. A 10% to 15% sequential drop in eMMC and UFS means total sales rose 24% while one of the three largest product groups shrank. The rest of the growth therefore came from SSD controllers and the other lines. The wire excerpt does not split out Ferri or boot drive revenue, so the Thursday call is where that breakdown should come out.

Why it matters: Silicon Motion describes itself as moving from "a consumer-focused NAND flash controller maker to a diversified leader in controllers and storage solutions," in CEO Wallace Kou's words from the Q2 release. A falling embedded line alongside fast SSD and solutions growth is what that transition would look like. But eMMC and UFS controllers go mostly into smartphones and IoT devices. A sequential drop there raises a question for the call: is it customer inventory timing, or memory supply limits? Management said in Q2 that it was dealing with "memory and storage supply challenges."

Context: valuation, coverage and storage peers

On the morning of Oct 28, 2026, before the results, China Renaissance started covering Silicon Motion with a Buy rating and a $300 price target (wire). That rating and target are the analyst's, not ours. The company's market cap is about $6.9 billion on our data sheet. A pre-earnings profile put the trailing P/E at about 23.9, close to its one-year low, even as consensus called for 233% EPS growth.

The bar for the stock is high. After the Q2 report on July 30, 2026, shares rose 21% in premarket trading to $254. Revenue that quarter beat estimates by 11.8% and EPS of $2.43 per ADS beat the $2.11 forecast. If the Q3 implied beat of about 5.7% holds, it is smaller than Q2's 11.8%. That alone could shape how the stock trades, apart from the absolute growth rate.

Elsewhere in storage on the same day, Summit Insights cut Seagate Technology (STX) from Buy to Hold on Oct 28, 2026 (wire). Seagate sells hard drives rather than NAND controllers, but both depend on data center storage spending. Among chip companies reporting the same afternoon, FormFactor (FORM) reported Q3 revenue of $280.5 million, up 8.6% from a year earlier (wire). Next to that, Silicon Motion's 131% stands out.

What to watch on the Oct 29 call

• Gross margin versus the 50% to 51% guide. Mix favors higher-value SSD and solutions products, which would usually help. Memory supply costs could work against it.
• EPS versus the $3.33 consensus, and operating profit versus the $142.7 million to $154.2 million guide.
• Fourth-quarter revenue guidance. After 32% and 24% sequential gains in Q2 and Q3, the Q4 range will show whether growth can keep going from a base near $559 million.
• Why embedded sales fell. Management needs to say whether the 10% to 15% sequential decline is temporary or part of the mix shift.
• MonTitan enterprise SSD ramp. It is the newest product line management named as a Q3 growth driver.
