How this view changed
- · Rating raised from Low to Medium. Results, 9 November 2026: Onto Innovation reported third-quarter 2026 revenue of $409.7 million, above the top of its $380–400 million guidance, and guided fourth-quarter revenue to $430–450 million with backlog above $1.3 billion.
Price against the kill line
4.9% clear of its kill line on the 13 November 2026 close.
How to read this
The red mark is the price level of the published kill line: a close through it (a weekly close, on a weekly line) would prove the research note wrong on price. The dot is where the stock closed on 13 November 2026; a dot left of the mark has closed through its line.
The scale is stretched near the line, so close calls are easy to see. More than 8% from the line, the stock reads well clear, with a hollow dot to show the figure is off the drawn scale.
The kill line is the research note's own test. The portfolio sells on business facts, not on a price. How the portfolio decides
Three months against the kill line
Daily closes, to . Red: the kill line, a daily close below $194.04, set on 12 November 2026. The shares are down 42.0% since the close; the S&P 500 is down 2.1% over the same sessions. Figures in the note can cover a different window.
Kill line
A daily close below $194.04, the last close before the 9 November 2026 third-quarter report, which would erase the post-results gain; fourth-quarter revenue below the $430 million low end of guidance would also prove the call wrong.

The thesis
Onto Innovation's shares are modestly more likely than not to beat the S&P 500 over the next three months. The 9 November 2026 third-quarter report beat the top of the company's own guidance and raised the outlook, while the shares still trade 44.4% under their 52-week high. The fourth-quarter report, expected in early 2027 against a $430–450 million revenue outlook, settles whether that growth holds.
Third-quarter revenue was $409.7 million, up 87.8% from $218.2 million a year earlier, against guidance of $380–400 million, according to the company's 8-K. Backlog rose to more than $1.3 billion, up from just over $1 billion at the second-quarter report on 6 August 2026. Chief executive Mike Plisinski said the company expects 2026 revenue growth above 45%.
The price reflects a sharp expected slowdown in 2027. The shares closed at $215.06 on 11 November 2026, down 36.3% over three months. On 10 November 2026 and 11 November 2026, seven brokers cut their targets despite the beat: Morgan Stanley, RBC Capital, Stifel, Evercore ISI, Jefferies, Needham and Freedom Broker. The rating is Medium because the reported numbers now run ahead of a share price driven by fears about 2027 equipment spending. Those fears, more than the quarter itself, decide the next three months.
Bullish and bearish views on Onto Innovation Inc.
The bull case on Onto Innovation Inc. (ONTO), in brief: third quarter beat the top of guidance. The bear case: brokers cut targets after the beat.
Bull case
- Third quarter beat the top of guidance. Revenue of $409.7 million on 9 November 2026 topped the $380–400 million range and MarketBeat's $392.08 million consensus. Non-GAAP earnings per share (EPS) of $2.44 beat the $2.30 consensus. Non-GAAP gross margin rose to 57.6% from 54.0% a year earlier.
- Fourth-quarter outlook sits above estimates. On 9 November 2026 the company guided fourth-quarter revenue to $430–450 million and non-GAAP EPS to $2.59–2.79. Benzinga reported consensus at $413.253 million and $2.48.
- Backlog grew again. Backlog passed $1.3 billion at the 9 November 2026 report, up from just over $1 billion on 6 August 2026. The company reported record revenue in advanced nodes, driven by Atlas G6 adoption, and in advanced packaging, driven by its Dragonfly G5 and Firefly inspection systems.
- The largest customer held its budget. Focus Taiwan and TrendForce reported that TSMC kept its 2026 capital spending range at $60–64 billion on 15 October 2026. TSMC is Onto's largest customer.
- Cash covers the commitments. Onto held $1.25 billion of cash, cash equivalents and marketable securities at the end of the third quarter. Operating cash flow for the quarter was about $79 million, according to the 9 November 2026 8-K.
Bear case
- Brokers cut targets after the beat. MarketBeat reported on 10 November 2026 that Morgan Stanley cut its target to $325 from $360, RBC Capital to $350 from $400 and Stifel to $305 from $350. Evercore ISI cut to $250. Lower targets on raised estimates mean brokers are paying a smaller multiple for 2027 earnings.
- GAAP earnings trail the adjusted figure. Third-quarter GAAP diluted EPS was $0.95, against $2.44 non-GAAP. The gap includes a $40.8 million unrealized loss on the 27% Rigaku stake. Fourth-quarter guidance includes $18–22 million of restructuring expense.
- The shares sit below both moving averages. The $215.06 close on 11 November 2026 is under the 50-day average of $249.93 and the 200-day average of $260.07.
- Sector selloffs hit Onto harder than peers. The shares fell 7.06% on 12 October 2026 after ChangXin Memory Technologies (CXMT) reported progress on next-generation DRAM. Lam Research fell 2.91% and KLA 2.79% that day.
- A few customers drive revenue. TSMC, Samsung and SK Hynix account for most of Onto's revenue. A spending cut at either Korean memory maker would hit the high-bandwidth memory (HBM) inspection orders in the backlog.
Price setup
The shares closed at $184.82 on 4 November 2026 and $155.99 on 5 November 2026, then rose to $173.28 on 6 November 2026. They closed at $197.51 on 10 November 2026, the first session after the report, and at $215.06 on 11 November 2026. Most of the gain after the report came on 11 November 2026, the session of a broad rally in AI stocks.
The 50-day average of adjusted closes is $249.93 and the 200-day average is $260.07, both as of 11 November 2026. The 52-week intraday high is $386.46, set on 30 June 2026. The 52-week closing low is $124.09, set on 18 November 2025. The $1.5 billion convertible notes issued on 21 May 2026 convert at about $381.80, well above the last close. They do not threaten to dilute shareholders at current prices.
Catalysts ahead
- ~17 December 2026 (est.): Micron fiscal first-quarter 2027 results and capital spending outlook. Micron's spending plan shows whether memory makers are holding HBM equipment budgets after CXMT's DRAM progress, which drives part of Onto's backlog.
- ~14 January 2027 (est.): TSMC fourth-quarter 2026 results and 2027 capital spending guidance. TSMC is Onto's largest customer; a 2027 budget above the 2026 range of $60–64 billion would support advanced-packaging inspection demand, while a flat or lower budget would support the 2027 slowdown the share price reflects.
- ~5 February 2027 (est.): Onto Innovation fourth-quarter 2026 results and first-quarter 2027 outlook. Revenue within or above the $430–450 million guidance, and a first-quarter outlook that holds that level, would show the $1.3 billion backlog converting into sales.
What would change the view
A daily close below $194.04, the last close before the 9 November 2026 third-quarter report, which would erase the post-results gain; fourth-quarter revenue below the $430 million low end of guidance would also prove the call wrong.
The risks this note tracks, each with what would confirm it:
- Customers cut 2027 equipment budgets, so falling valuation multiples turn into falling earnings estimates. Confirmed by: TSMC guiding 2027 capital spending below its 2026 range of $60–64 billion, or Samsung or SK Hynix trimming 2027 equipment plans.
- Memory makers grow cautious on 2027 equipment budgets after Chinese DRAM progress. Confirmed by: Micron, SK Hynix or Samsung lowering capital spending plans after CXMT's 12 October 2026 DRAM announcement.
- Backlog does not convert into fourth-quarter shipments. Confirmed by: fourth-quarter revenue below the $430 million low end of guidance, or disclosed postponement of Atlas G6 or advanced-packaging orders.
- Customer concentration turns a single schedule change into a large estimate cut. Confirmed by: a first-quarter 2027 outlook below the fourth-quarter 2026 result, or a named customer deferring HBM or advanced-packaging tool deliveries.
- Further mark-to-market losses on the Rigaku stake weigh on GAAP earnings. Confirmed by: another unrealized loss on the Rigaku investment in the fourth-quarter 2026 results as Rigaku shares or the yen weaken.
What it trades with
Onto trades with semiconductor equipment peers Lam Research and KLA, but has fallen further than either in sector selloffs, as it did on 12 October 2026. It also follows TSMC's capital spending and memory makers' budgets, so TSMC's and Micron's next reports move it directly. Sentiment about AI spending moves it too: the shares rose from $197.51 to $215.06 on 11 November 2026, the session in which Benzinga counted 17 AI stocks, including CoreWeave, up more than 10%.
