Onto Innovation faces shareholder investigation. Last updated: September 2, 2026 6:52 am NEW YORK - September 2, 2026 (STL.News) Semiconductor equipment company Onto Innovation Inc. is the subject of a shareholder investigation announced by a securities law firm, which says it is examining possible breaches of fiduciary duties by certain company officers and directors. The investigation involves Onto Innovation Inc. (NYSE: ONTO), a Wilmington, Massachusetts-based semiconductor process-control company serving manufacturers across the global semiconductor industry. Levi & Korsinsky announced the investigation Tuesday, September 1, saying it had begun examining "possible breaches of fiduciary duties." The firm is inviting current Onto Innovation shareholders to contact its attorneys for additional information. The announcement is an investigation notice and does not mean that Onto Innovation, its officers or its directors have been found to have violated securities laws or breached their fiduciary duties. The firm's announcement did not identify specific officers or directors alleged to have engaged in misconduct, describe the conduct underlying its investigation, or announce that it had filed a lawsuit. It also did not identify a class period, lead plaintiff deadline or alleged shareholder losses. What is Levi & Korsinsky investigating? Levi & Korsinsky provided few details concerning what prompted the investigation. The New York-based law firm said only that it "commenced an investigation of Onto Innovation Inc. concerning possible breaches of fiduciary duties." That distinction is important for investors. Law firms frequently conduct preliminary investigations to determine whether facts support potential shareholder claims. An investigation does not necessarily result in litigation, and the announcement itself does not establish that Onto Innovation or any of its executives violated the law. The firm's announcement identifies attorney Joseph E. Levi as a contact for current Onto Innovation shareholders and says shareholders can request information at no cost or obligation. Recent regulatory filings provide additional context about the company but do not establish the reason for the firm's investigation. Onto Innovation filed its most recent quarterly report with the Securities and Exchange Commission on August 6. In that filing, the company said it is periodically subject to legal proceedings and claims arising in the ordinary course of business. Management said potential liabilities from current disputes were not expected to affect the company's interim consolidated financial statements materially. The filing also said Onto Innovation's management evaluated its disclosure controls and procedures as of June 30 and concluded they were effective at the reasonable-assurance level. Onto Innovation recently reported record revenue. The investigation announcement comes amid substantial growth and corporate activity at Onto Innovation. On August 6, the company reported record second-quarter revenue of approximately $343.1 million, compared with approximately $253.6 million during the comparable quarter in 2025. Onto Innovation reported second-quarter net income of approximately $60.1 million, up from approximately $33.9 million during the year-earlier quarter. The company said revenue increased nearly 18% sequentially and that its advanced-nodes business generated record quarterly revenue as semiconductor customers increased spending on artificial intelligence, high-performance computing, advanced packaging, and memory technologies. "Onto Innovation is positioned well across several key technology inflections driving next-generation AI and high-performance compute devices," Chief Executive Officer Mike Plisinski said when the company announced its second-quarter results. Onto also ended the second quarter with approximately $1.88 billion in cash and short-term investments. For the third quarter ending September 30, management projected revenue between $380 million and $400 million, and GAAP diluted earnings of approximately $1.54 to $1.70 per share. Onto completed its acquisition of Semilab USA LLC in November 2025 for total consideration initially valued at approximately $526.6 million, according to its latest quarterly filing. The acquisition expanded Onto's capabilities in wafer contamination monitoring, materials characterization, and surface-charge metrology. Onto reported that Semilab USA contributed approximately $20.7 million in revenue during the second quarter and approximately $46.1 million during the first six months of 2026. Semilab USA generated an operating loss of approximately $4.5 million during the second quarter and $9 million during the six months. Onto has also pursued an investment in Rigaku Holdings Corp. In April, the company entered an agreement to acquire approximately 27% of Rigaku for roughly $710 million. Onto said it would receive the right to nominate one Rigaku director to Rigaku's board. Onto disclosed executive and director trading. Innovation's August 6 quarterly filing also disclosed Rule 10b5-1 trading plans involving several officers and directors. CEO Michael Plisinski terminated a trading plan on April 29 that could have allowed the sale of as many as 65,937 shares. According to the filing, no transactions occurred under that plan before it was terminated. Plisinski subsequently adopted another Rule 10b5-1 plan on May 28 providing for potential sales of up to 50,000 shares through February 2027. Senior Vice President, General Counsel and Corporate Secretary Yoon Ah E. Oh terminated a separate Rule 10b5-1 plan on May 5. Onto reported that no transactions occurred under that plan before its termination. Director Susan D. Lynch adopted a Rule 10b5-1 plan on May 22 providing for potential sales of as many as 1,000 shares. Director David B. Miller adopted another plan in June covering as many as 2,000 shares. Corporate executives and directors commonly use Rule 10b5-1 plans to establish predetermined arrangements to buy or sell company securities. The existence, adoption, termination, or execution of such a plan does not by itself indicate improper insider trading or other misconduct. Onto explains to investors that company insiders use Rule 10b5-1 plans for liquidity and diversification. NothKorsinsky's & Korsinsky's September 1 announcement states that these trading plans are connected to its investigation. ONTO shares decline before investigation announcement. Onto Innovation shares closed Tuesday, September 1, at approximately $256.37, down $10.84, or about 4.1%, from the previous close of $267.21. The shares traded between approximately $253.40 and $263.98 during the session. The law firm announced the investigation at 7:50 p.m. Eastern Time, after regular U.S. stock-market trading on Tuesday. Therefore, Tuesday's regular-session decline occurred before the announcement, and investors should not attribute it to the news. ONTO shares have traded in a wide range over the past year, with a reported 52-week range of approximately $101 to $386.46. Investors will now be watching whether Levi & Korsinsky provides additional information explaining the factual basis for its inquiry and whether another securities law firm begins a separate investigation. What happens next for Onto Innovation shareholders? At this stage, the matter remains preliminary. Levi & Korsinsky has announced an investigation but has not announced the filing of a shareholder derivative lawsuit or securities class action arising from the investigation. The September 1 notice also does not establish a class period or deadline for investors to seek appointment as lead plaintiff - information typically associated with an already-filed federal securities class action. Current shareholders therefore should distinguish between a law firm's request for information and an actual proceeding. Onto Innovation's SEC filings, meanwhile, show a company reporting substantial revenue growth while simultaneously managing acquisitions, investments, restructuring expenses and significant capital-market activity. Whether the shareholder investigation develops into litigation will depend on what the investigating attorneys uncover and whether they find a viable legal claim. As of publication, no court has found Onto Innovation, its officers or its directors liable for the potential fiduciary-duty issue in Levi & Korsinsky's announcement.

Take control of your process: Onto Innovation at SEMICON Taiwan 2026. News highlights Sep 2, 2026, 08:00 0 Credit: Onto This year's SEMICON Taiwan will be packed with discussions about artificial intelligence and the on-wafer challenges it's creating, where the advanced node and emerging technology worlds collide. And at the center of it all is the need for better process control at a reduced cost-of-ownership (CoO). Right now, manufacturers are being told to buy high-priced tools designed for the front-end advanced node world - often delivering more performance than needed at a CoO that breaks the bank. It's time to break the cycle and deliver what customers want and need at a CoO that is designed to meet the needs of their business and not simply the needs of the OEM. Enter Onto Innovation.Take control of your process and break free from costly, unnecessary platforms and patchwork solutions that prevent you from achieving truly connected process control. Here's how Onto Innovation fights the status quo and puts manufacturers in control. Advanced Node Logic: Controlling Structures at the Limits of Physics At the leading edge, 3D architectures are evolving fast. Gate-all-around (GAA) nanosheets require control of individual sheet dimensions, while future complementary field-effect transistor (CFET) structures will intensify 3D metrology requirements. Both demand precise nanowire control with the data richness and enhanced signal-to-noise ratio (SNR) needed to extract more than a single dimension from a single measurement. Powered by Ai Diffract modeling software, Onto's optical critical dimension (OCD) portfolio provides the precision to identify dimensional drift in complex GAA and CFET structures. Onto's films metrology portfolio measures the ultra-thin oxide, high-k metal gate, and P/N metal stack films that make up these devices. Together, these metrology solutions help manufacturers catch process drift before it becomes a downstream issue. Advanced Memory: Keeping Pace With Vertical Scaling As 3D DRAM and 3D NAND scale vertically and device density increases, metrology has to keep pace. Manufacturers face increasingly stringent requirements for high spectrum resolution and sensitivity, and Onto's OCD and films metrology portfolio delivers the tools to stay in control as memory scales. Silicon Photonics: Controlling a Fundamentally New Kind of Device Silicon photonics (SiPh) and co-packaged optics (CPO) are scaling toward broader high-volume manufacturing (HVM) adoption. These architectures can integrate laser sources, waveguide-based silicon chips, micro-lenses, and opto-electronic converters, with each introducing unique process-control challenges. Defects can show up anywhere along the optical path - in the V-grooves and micro-lens arrays that couple and align light, the waveguides that route it, the EEL/VCSEL devices that generate it, and the module-level packaging (through glass vias, bump, hybrid bonding, and reflectors) that holds it all together. Any of these defects can negatively impact yield and performance. Onto's metrology and inspection portfolio enables manufacturers to address these key touchpoints with confidence. Materials Intelligence: Control That Starts Below the Surface Not every problem appears as a visible defect. Charge trapping, interface states, dopant profiles, and crystalline defects can erode device performance and reliability long before a part reaches test - often beyond the reach of standard metrology recipes. Onto's materials intelligence tools are built for this layer of control: FAaST for charge and interface characterization, CnCV and QUAD for yield-critical electrical insights, Aspect S for material and structure characterization of high aspect ratio (HAR) trenches and TSV, and Celero PL for crystalline defect intelligence. With Onto, manufacturers are able to identify the variations dimensional measurements alone cannot see. Advanced Packaging: Managing Complexity Where Device Types Converge Logic, memory, and increasingly photonics come together in an advanced package to act as one system. Process steps like hybrid bonding, TSV, silicon thinning, and copper pad recess and dishing/topography control introduce errors that don't exist in front-end flows. Copper that protrudes or recesses even slightly at a bond interface, for example, can undermine an otherwise perfect hybrid bond; this is why hybrid bonding requires tight control of surface topography, including copper pad recess and dishing/topography, along with inspection designed to catch the sub-micron, low contrast, and non-visible defects standard inspection tools can miss. Interposers, meanwhile, introduce their own set of challenges one layer down, where measuring HAR deep trench capacitors and TSV is as demanding as it is in any 3D memory stack, and where high-speed infrared (HSIR) inspection is needed to catch defects below the surface. This need for visibility is just as important, if not more so, in an AI package. Each component in an AI package- GPU or CPU, multiple HBM stacks, an interposer, a panel substrate, and CPO - is a process control touchpoint. Onto's portfolio addresses these directly: logic OCD and film metrology for the GPU/CPU, HBM bump and RDL inspection for the memory stack, interposer inspection for the layer connecting them, panel lithography and inspection for the substrate, and SiPh/CPO module inspection wherever optics are integrated - all tied together by process control and analytics software. Dragonfly G5: One Platform for Multiple Device Types The Dragonfly G5 system shows what taking control across device types looks like. The system delivers sub-micron defect sensitivity down to 150nm, with best-in-class throughput across front-end, back-end, and advanced packaging applications. That versatility extends beyond traditional wafer-based manufacturing. Specialty and photonics opportunities are evaluated by application, on a single platform that handles wafers and 310x310mm panels, including glass. This unrivaled versatility is the result of several complementary inspection technologies on one platform, each one designed for a different kind of defect: brightfield and darkfield imaging for standard inspection, 3Di technology for bump metrology, a new illumination mode for sub-micron, low-contrast defects (e.g. CMP, hybrid bonding), Clearfind technology for non-visible defects, and HSIR inspection for sub-surface defects. Outfitted with TrueADC Turing machine learning classification software, the Dragonfly G5 helps manufacturers reduce nuisance defects and improve defect matching and classification accuracy. The result is a platform that follows manufacturers across device types rather than forcing them to qualify a different tool for each type. The same underlying system supports front-end and back-end inspection, advanced packaging steps like hybrid bonding and 2.5D integration, and selected specialty/photonics inspection applications. Taking Control, Device by Device Advanced node logic, advanced memory, silicon photonics, advanced packaging, critical films, and AI packages feature different physics, materials, and failure modes. Onto's approach to each is the same: give manufacturers a clear, connected view of their process so problems are addressed before they become expensive. That's what taking control of your process really means - not one tool built for one device, but a portfolio designed to give manufacturers visibility and confidence across the full range of their products. SEMICON Taiwan attendees can find the Onto team at Booth L0728, September 2-4. Stop by and learn how comprehensive process control solutions can help you take control of your process, yield, and future roadmap.
