Management Comments

• "The qualification of the 3Di technology for 3D bump metrology by two customers supporting HBM and another customer supporting 2.5D logic applications for AI is another great step forward by the Onto Innovation team in advancing our leadership in advanced packaging process control."
• "With several of our next generation Dragonfly systems for high resolution 2D applications expected to begin shipping in the next few weeks, we are delivering the comprehensive solutions our customers need, not only to control processes today, but also for their next generation technologies."

Industry Context

The semiconductor industry is experiencing significant growth in advanced packaging, particularly for high bandwidth memory (HBM) and AI-driven 2.5D logic applications. Onto Innovation's success in qualifying its Dragonfly 3Di technology with major HBM customers and securing orders for AI packaging positions it well within this high-growth segment. The shipment of Atlas G6 OCD systems further indicates demand for advanced process control solutions in logic and memory, aligning with the broader industry's push for higher performance and miniaturization.

Comparison to Industry Standards

• NA

Stakeholder Impact

• Shareholders: Positive impact due to exceeding guidance, strong cash flow, and strategic product qualifications in growth markets (HBM, AI). Potential for future growth driven by new product shipments.
• Customers: Positive impact as new technologies (Dragonfly 3Di, Atlas G6 OCD) are qualified and shipped, providing advanced process control solutions for next-generation technologies.
• Employees: Continued focus on advancing leadership in advanced packaging process control suggests stability and ongoing innovation efforts.
• Suppliers: Continued demand for components to meet customer demand for new systems.

Next Steps

• Additional shipments of Atlas G6 OCD systems are scheduled for the fourth quarter.
• Several next-generation Dragonfly systems for high-resolution 2D applications are expected to begin shipping in the next few weeks.

Key Dates

Recommendation

While Onto Innovation demonstrated strong operational execution by exceeding guidance and securing key qualifications in high-growth areas like HBM and AI packaging, the year-over-year GAAP declines in revenue and net income for Q3 2025 suggest a mixed financial picture. The company's strong cash position and positive outlook for Q4 2025 are encouraging, but the broader semiconductor market's cyclical nature and competitive landscape warrant a cautious "hold" recommendation. Investors should monitor the successful integration of new technologies and the realization of anticipated benefits from the Semilab acquisition (mentioned as a risk) before considering a stronger position.
