Onto Innovation (ONTO) Stock Forecast & Price Target

Onto Innovation is supported by powerful secular demand from AI-driven semiconductor spending, with WFE expected to grow about 30% in 2026 and more than 35% in 2027, while the company’s systems revenue should outgrow WFE through 2028. Its Dragonfly and Atlas platforms deepen exposure to high-growth advanced packaging and advanced nodes, where advanced packaging is on track for 80% growth this year, advanced nodes grew to a record ~$120M in Q2 2026, and gross margin improved to 57.0%. The outlook is further strengthened by minimal China exposure at roughly 4% of revenue, a recurring Software and Services base of $192.7M in FY25A, and expanding opportunities in silicon photonics and panel-level packaging.

Onto Innovation is facing a negative outlook because its growth is heavily dependent on advanced packaging demand that could moderate sharply if AI accelerator spending slows, customers digest inventory, or hybrid bonding adoption slips beyond the current leading edge. The company also faces meaningful competitive pressure from KLA and ASML in advanced packaging inspection, while panel-level packaging and silicon photonics appear too early to offset weakness, with real volume panel production not expected until 2028 and silicon photonics SAM not reaching $500M until 2030. Given exposure to foundry capex cuts at TSMC and slowing leading-edge demand at Samsung and Intel, any delay in these ramps could leave Onto Innovation with weaker revenue momentum and reduced share in key inspection steps.
