Onto Innovation's week centers on its Dragonfly G5 product gaining momentum, with AI packaging demand driving qualifications, volume orders and an upgraded 2026 growth outlook. This builds on the company's Q2 2026 results, which showed revenue of $343.13 million, up 35.3% year-over-year, and adjusted EPS of $1.93 versus an estimate of $1.68, alongside positive Q3 guidance. Brokerage sentiment remains favorable, with nine firms currently rating the stock buy, none at hold or sell, and a consensus price target of $386.36 implying 33.8% upside from current levels; a separate report cited an average target of $378.00 from thirteen brokerages. A shareholder investigation notice regarding potential fiduciary breaches by officers and directors has also surfaced this week.
The stock closed at $288.74, up 0.4%, sitting above both its 50-day average of $280.83 and 200-day average of $250.54, with the shorter average above the longer one. The GekkoIndex reads 55.1, placing it in the Neutral zone, down 4.6 over the past five sessions. Price sits 2.1% above Gekko Fair Value of $282.90, keeping the two closely aligned.

Onto Innovation builds inspection and measurement equipment for manufacturers who need to catch defects and fine-tune their production lines. Its lineup spans large-defect scanning tools, optical metrology systems that read surfaces in two and three dimensions, and lithography machines, paired with software that analyzes the data these tools collect. The company has built its reputation around this pairing of physical inspection gear with analytical software aimed at improving output quality and reducing waste in complex manufacturing.
Some of its products are sold as dedicated machines built for a single purpose, like spotting large surface flaws, printing patterns during packaging, checking probe cards, or gauging the thickness of clear and opaque film layers. Others take the form of software that oversees anything from one machine to operations spanning a whole plant. Alongside these, the company sells replacement parts and licenses for its software. Its buyers include producers of chips, packaged devices, silicon wafers, LEDs, VCSELs, MEMS components, CMOS image sensors, power electronics, RF filters, and storage media, plus companies working in industrial and scientific research.
The business dates back to 1940, when it started under the name Rudolph Technologies, Inc., and it now runs out of Wilmington, Massachusetts. Its stock trades on the NYSE under the ticker ONTO.
