Onto Innovation's Q1 2025 Results: A Semiconductor Process Control Leader in the Fast Lane

Onto Innovation Inc. (ONTI) has delivered another quarter of exceptional performance, reinforcing its position as a key player in the semiconductor process control market. Q1 2025 results reveal accelerating momentum in advanced node technologies and metrology solutions, with record financial metrics and strategic wins positioning the company for sustained growth.

Financial Highlights: A Strong Foundation
Onto’s Q1 2025 revenue hit $267 million, marking the seventh consecutive quarter of year-over-year growth. Gross margins expanded to 54% (GAAP) and 55% (non-GAAP), while operating income surged to $63 million (GAAP) and $76 million (non-GAAP). The company’s cash generation was equally impressive, with $92 million generated from operations—35% of revenue—highlighting operational efficiency and robust liquidity.

Product-Specific Growth: Advanced Nodes and Metrology Dominance
The standout performance came from advanced node technologies, with revenue doubling sequentially. This segment includes leading-edge DRAM, NAND, and gate-all-around devices, all critical for next-gen semiconductor applications. The Iris™ Film Metrology platform also saw over 25% sequential revenue growth, fueled by new customer wins and full-year projections for record performance.

In 3D Bump Metrology, Onto delivered multiple system shipments in Q1, with more planned for Q2. This technology is vital for advanced packaging, a sector experiencing rapid adoption as chipmakers shift toward heterogeneous integration and smaller geometries.

CEO Perspective: Aligning with Industry Transitions
CEO Michael Plisinski emphasized Onto’s alignment with two critical trends: the shift to advanced nodes and the rise of advanced packaging. He noted that demand for 2D/3D inspection solutions is intensifying as customers prepare for technology transitions expected in late 2025 and early 2026. This timing aligns with industry forecasts for 3nm and 2nm node rollouts, where precision metrology is indispensable.

Q2 2025 Guidance: Prudent but Optimistic
Guidance for Q2 projects revenue between $240 million and $260 million, with non-GAAP EPS anticipated between $1.21 and $1.35. While slightly below Q1’s record levels, this range reflects normal seasonality and cautious optimism about near-term demand. Analysts will watch closely for execution against these targets, particularly as supply chain dynamics remain a wildcard.

Risks and Considerations
The release acknowledges risks such as supply chain constraints, macroeconomic headwinds, and geopolitical trade regulations. These factors could impact customer spending and production timelines. However, Onto’s strong cash flow and focus on high-margin metrology solutions—critical for cutting-edge semiconductor production—act as mitigants.

Conclusion: A Compelling Investment Case
Onto Innovation’s Q1 results underscore its status as a beneficiary of secular trends in advanced semiconductors and packaging. With 7 straight quarters of revenue growth, a 55% non-GAAP gross margin, and a pipeline of wins in high-value markets, the company is well-positioned to capitalize on the $120 billion+ semiconductor equipment market’s expansion.

The doubling of advanced node revenue and Iris’s 25% sequential growth signal strong demand from foundries and memory manufacturers, while 3D Bump Metrology shipments reflect the shift toward advanced packaging—a segment projected to grow at a 12% CAGR through 2030.

Investors should note that Onto’s cash generation (35% of revenue) and non-GAAP profitability (36% operating margin) suggest a company executing at a world-class level. While near-term risks exist, the secular tailwinds driving Onto’s business—smaller chip geometries, AI-driven compute demand, and 3D packaging—make it a compelling play on the future of semiconductor manufacturing.

For those with a long-term horizon, Onto Innovation’s Q1 results and strategic positioning argue for a buy rating, particularly as it enters what could be a pivotal period for advanced node adoption in late 2025 and beyond.
