Key Takeaways

Will the fourth-quarter guide keep revenue rising?

The street's FY26E revenue of US$1,874m, less the US$793m reported in the first half and the US$530m midpoint of the 3Q26 guide, leaves US$551m for the fourth quarter, up 4% QoQ. A fourth-quarter guide above that level puts the full year ahead of the street; weak smartphone and PC demand is the risk to it, and enterprise SSD controllers and Ferri boot drives are what management is counting on.

3Q26 revenue guided to US$519-541m, up 15-20% QoQ

Management guided 3Q26 revenue to US$519-541m, up 114-124% YoY, with non-GAAP gross margin of 50.0-51.0%, and the street expects US$532.8m and non-GAAP EPS of US$3.30 per ADS. Revenue has come in above the top of the guided range in each of the last four quarters, most recently US$451.0m in 2Q26 against a US$393-411m guide.

Can operating margin reach 28% now and 30% by year-end?

Management guided 3Q26 non-GAAP operating margin to 27.5-28.5% from 23.1% in 2Q26, which at the revenue midpoint holds operating expenses near US$120m while revenue rises 18%. The street's FY26E EPS of US$11.19 per ADS needs a fourth-quarter operating margin of about 31%, in line with management's target to exit 2026 above 30%.

Inventory rose to US$673m and the US$1.15bn notes refilled cash

Inventory reached US$673m at the end of June from US$422m at December as Ferri and boot drive solutions, which include the NAND, grew to nearly 30% of revenue, and operating cash flow was negative in both quarters of 1H26. The August notes, zero coupon and convertible at US$380.50 per ADS, added US$1,127m of net proceeds to US$182m of cash, and the release should show whether inventory is still rising with NAND prices and what the cash is for.

Shares at 16.8x street FY26E earnings after a 44% fall

At US$187.96 the shares trade at 16.8x the street's FY26E non-GAAP EPS of US$11.19 and 12.2x FY27E US$15.35, down from about 30x FY26E in July. Memory and storage stocks fell through October on reports of CXMT's progress in DRAM and worries about AI spending; Silicon Motion announced nothing in the period beyond its results date and a 15% dividend increase.

Company snapshot

Silicon Motion Technology (SIMO US) designs NAND flash controllers, the chips that manage how data is written to and read from flash memory, and sells them to NAND makers, storage module houses and device OEMs. Its product lines are client SSD controllers, eMMC and UFS embedded controllers for phones and other devices, Ferri industrial and automotive storage modules with enterprise boot drives, and the MonTitan platform for enterprise and AI-server SSDs. Ferri and boot drive solutions grew to nearly 30% of revenue in 2Q26 from 4% a year earlier. The company is listed on Nasdaq as American depositary shares, each representing four ordinary shares.

Expectations snapshot

Silicon Motion reports 3Q26 results after the US market close on 28 October, with the earnings call on 29 October at 8:00am Eastern time (company release, 8 October). The company guides one quarter at a time, so the full-year picture rests on management's July statement that 2026 revenue will more than double and on the street's numbers.

Recent developments

The results date is set and the dividend rises 15%. Silicon Motion set the 3Q26 release for after the US close on 28 October (company release, 8 October) and on 16 October raised its annual dividend to US$2.30 per ADS from US$2.00, paid in four installments of US$0.575, the first to holders of record on 5 November and payable on 19 November (company release, 16 October).
A US$1.15bn zero-coupon convertible closed in August. On 13 August the company closed an upsized US$1,150m offering of 0.00% convertible senior notes due 2031, convertible at about US$380.50 per ADS, a 65% premium to the US$230.61 close on 10 August. Net proceeds were US$1,127m, for general corporate purposes and repayment of its credit agreement, against cash and restricted cash of US$182m at the end of June. Holders can require repurchase on 15 August 2029 (company releases, 10 and 13 August).
Memory and storage stocks sold off through October. The group fell on 8 October, when Samsung's preliminary third-quarter operating profit of about KRW107tn set a record but missed forecasts, and again from 12 October on reports of CXMT's progress in DRAM, including server memory. On 22 October SanDisk fell 8%, Western Digital 7% and Micron 6% as the selloff extended, after Goldman Sachs had called the CXMT threat overblown on 16 October (Benzinga, 8 October; CNBC, 13 October; 24/7 Wall St, 22 October).
Silicon Motion shares fell with the group, on no company news. The shares closed at US$187.96 on 22 October, down 34% from US$285.78 on 7 October and 44% below their 22 June high of US$336.90, while still roughly double their level of a year earlier. The company's only announcements in the period were the results date, the dividend increase and an automotive cybersecurity process certification (Nasdaq closing prices; company releases).
TrendForce expects NAND contract prices up 15-20% in 4Q26, with enterprise SSDs the only category accelerating. In its 30 September forecast TrendForce projected overall NAND contract prices up 15-20% QoQ in the fourth quarter. It expects enterprise SSD price gains to accelerate on AI inference demand, client SSD increases to be restrained as PC makers draw down inventory and cut drive capacities in mainstream models, and eMMC and UFS prices to rise on very limited volumes because smartphone makers are buying only the minimum needed to keep supply relationships (TrendForce, 30 September).
Micron reported record NAND revenue and Phison's September sales rose again. Micron's fiscal fourth quarter to 3 September carried record NAND revenue of US$14.1bn, and its management said supply constraints should persist through fiscal 2027 and 2028 (Micron results, 30 September). Phison, a Taiwan controller and module maker, reported September revenue of NT$30.6bn, up 8% MoM and 370% YoY, on higher shipments and prices (Phison monthly report, 8 October).

Revenue is guided up 15-20% QoQ, and the street's full-year number needs only a 4% rise after that

Silicon Motion reports quarterly, so the last print and the guide are the tracking points. Revenue has risen for five straight quarters, from US$166.5m in 1Q25 to US$451.0m in 2Q26, and has come in above the top of the guided range in each of the last four: 4Q25 printed US$278.5m against a US$254-266m guide, 1Q26 US$342.1m against US$292-306m, and 2Q26 US$451.0m against US$393-411m.

The low end of the 3Q26 guide, US$519m, is up 15% QoQ and 114% YoY against 3Q25 revenue of US$242.0m; the top, US$541m, is up 20% and 124%. The street's US$532.8m sits just above the midpoint.
The street's FY26E revenue of US$1,874m, less the US$793.1m reported in the first half and the US$530m guide midpoint, leaves US$551m for the fourth quarter, up 4% QoQ. At the top of the 3Q26 range the implied fourth quarter is flat.
The street's FY27E revenue of US$2,430m, up 30%, averages US$608m a quarter, 10% above that implied fourth-quarter level.

Exhibit 3: Silicon Motion quarterly revenue, 1Q25 to 2Q26 reported, 3Q26E at the guide midpoint and 4Q26E implied by street FY26E (US$m)

Silicon Motion quarterly revenue rose from US$166m in 1Q25 to US$451m in 2Q26; the 3Q26 guide midpoint is US$530m and the street's FY26E implies US$551m in 4Q26E

Source: Silicon Motion quarterly results releases, FMP consensus estimates, Zero One Investment Research. 3Q26E is the midpoint of the company's US$519-541m guide; 4Q26E is street FY26E revenue of US$1,874m less reported 1H26 revenue and the 3Q26E midpoint.

In 2Q26 the growth came from Ferri and boot drive solutions, up 110-115% QoQ to nearly 30% of revenue, and from eMMC and UFS controllers, up 15-20% QoQ; SSD controllers rose 5-10%. The release will show whether the fourth-quarter guide carries the quarterly growth on, and which of the three lines is doing the work.

Management guided 3Q26 operating margin to 27.5-28.5% and expects to exit 2026 above 30%

Management guided 3Q26 non-GAAP gross margin to 50.0-51.0% and operating margin to 27.5-28.5%, from 50.2% and 23.1% in 2Q26. At the revenue midpoint that puts operating expenses near US$120m, level with the US$122m of 2Q26, so the margin gain comes from revenue growing against a flat cost base. On the July call management said it expects to exit 2026 with an operating margin above 30%.

The street's FY26E non-GAAP EPS of US$11.19 per ADS, against US$4.01 reported in the first half and US$3.30 expected for 3Q26, leaves about US$3.90 for the fourth quarter. On the implied US$551m of revenue and a 22% tax rate, that needs an operating margin of about 31%, the level management has set as its year-end target. The street's FY27E EPS of US$15.35, up 37% on revenue up 30%, assumes margins keep widening.

Our forecasts carry FY26E revenue of US$1,874m and FY27E revenue of US$2,430m, in line with the street. The 4Q guide is where we expect to part from it. A guide in our US$550-600m range would put FY26E revenue at US$1,873-1,923m, so the street's full-year number holds unless the guide falls short of US$551m.

Silicon Motion annual revenue was US$639m in FY23, US$804m in FY24 and US$886m in FY25; the street expects US$1,874m in FY26E and US$2,430m in FY27E

What to expect from the release

Exhibit 5: Silicon Motion non-GAAP gross and operating margin, 1Q25 to 2Q26 reported and 3Q26E at the guide midpoints (%)

Silicon Motion non-GAAP gross margin moved between 47% and 50% from 1Q25 to 2Q26 while operating margin rose from 9% to 23%; the 3Q26 guide midpoints are 50.5% and 28%

Source: Silicon Motion quarterly results releases, Zero One Investment Research. 3Q26E points are the midpoints of the company's guided ranges.

Revenue near the top of the US$519-541m range. The last four quarters each came in above the top of the guide, management said in July that its backlog and customer forecasts supported strong growth through the year, and Phison's September revenue, up 8% MoM, shows module-maker demand still rising into the quarter's end.
Non-GAAP operating margin inside the 27.5-28.5% band, with gross margin near 50.5%. Ferri and boot drive solutions include the NAND and so earn a lower gross margin than a controller sold alone; the 50-51% guide already reflects them at nearly 30% of revenue, with MonTitan and PCIe Gen5 controllers adding higher-margin sales on top.
A fourth-quarter revenue guide of US$550-600m. We expect a guide above the US$551m the street's full-year number implies: MonTitan is to reach 5-10% of revenue by year-end from a standing start, five more Tier 1 customers were due to ramp in the second half, and enterprise SSD is the one NAND category where TrendForce sees price gains accelerating. The risk sits in the consumer lines: management expects smartphone units to fall 10-15% in 2026, and TrendForce says phone makers are buying only the minimum eMMC and UFS volumes.
MonTitan customer and revenue detail. Two Tier 1 customers were in commercial production at the end of June and five more were to ramp in the second half; the release or the call should say how many are shipping and the share of revenue, and give a date for the 4nm PCIe Gen6 controller, which management has said ramps in 2028.
A balance sheet with about US$1.3bn of cash against US$1.15bn of notes. Inventory was US$673m at June, up from US$422m at December, and operating cash flow was negative in both quarters of 1H26. The third-quarter balance sheet is the first to show the notes, the repaid US$59m bank loan and whether inventory is still absorbing cash.

What investors should watch: three issues for the fourth quarter and 2027

Revenue for the quarter is guided and the street sits near the midpoint. Three issues in the release decide the fourth-quarter and 2027 numbers; for each we give our expectation and the specific thing to check, with MonTitan as a fourth item.

Will the fourth-quarter guide keep revenue rising? The street's full-year number needs US$551m in the fourth quarter, up 4% QoQ, and its FY27E of US$2,430m needs a run rate 10% above that. We expect a guide of US$550-600m. Check the range and its midpoint against US$551m, the commentary on eMMC and UFS and client SSD controllers, where smartphone and PC demand is weak, against Ferri and boot drives and MonTitan, and any remark on 2027 demand from the NAND makers that are outsourcing more controller development.
Does operating margin reach 28%, and is 30% still the exit rate? The street's FY26E EPS needs about 31% in the fourth quarter. Check gross margin against 50-51%, operating expenses against about US$120m, the fourth-quarter margin guide, the tax rate against the 22% management indicated, and the US$14.9-15.9m of stock compensation and dispute costs excluded from the non-GAAP figures.
What is the US$1.15bn for, and is working capital still absorbing cash? Operating cash flow was negative US$31m in 1Q26 and negative US$64m in 2Q26 as inventory rose, and no shares were repurchased in the first half. Check inventory against US$673m, operating cash flow, cash after the US$59m loan repayment, and any statement on acquisitions, NAND wafer commitments or buybacks. Holders can require repurchase of the notes on 15 August 2029, so the company has three years before the first call on that cash.
How many of the seven Tier 1 MonTitan customers are shipping? At 5-10% of revenue by year-end, MonTitan would be US$28-55m a quarter on the implied fourth-quarter revenue. Check the customer count, the revenue share, and the timing of the 4nm PCIe Gen6 controller for hyperscalers.

Valuation and peer comparables

At US$187.96 Silicon Motion trades at 16.8x the street's FY26E non-GAAP EPS of US$11.19 and 12.2x FY27E US$15.35, down from about 30x FY26E in late July. The peer median forward P/E of 17.1x (Exhibit 6) needs care in both directions: Micron and SanDisk trade at 4.9x and 5.9x next fiscal year's earnings, which sit at the top of a memory price cycle, while Seagate and Western Digital trade at about 17x and Marvell at 53x. On forward EV/Sales the shares trade at 3.3x against a 5.2x peer median.

Against its own history the multiple has halved while the estimates have risen. In late July the shares were US$270.90 and the street's FY26E EPS was near US$8.90; the 2Q26 beat and the 3Q26 guide have since lifted that estimate by about a quarter to US$11.19, and the shares have fallen 31%.

The fourth-quarter guide is the nearest number that can move these multiples. A guide at or above US$551m supports the street's full-year EPS and the 16.8x; a guide below it would take the FY27E figure down with it. For a company the street expects to grow revenue 30% in 2027 after more than doubling in 2026, the shares enter the print priced below the drive makers on forward earnings and above the memory makers, whose multiples rest on cycle-peak earnings.
