ONTO - Onto Innovation Inc.

Onto Innovation Inc. develops and sells process control and inspection equipment — specifically optical metrology systems and defect inspection tools used in semiconductor wafer manufacturing, with product lines including the Dragonfly and Atlas platforms. The core customer type is semiconductor fabrication facilities (fabs) and chip manufacturers purchasing capital equipment under direct sale contracts, with some recurring revenue from service and support agreements. Annual revenue is approximately $1.1B, with the primary geographic markets being Taiwan, South Korea, and the United States, reflecting the concentration of global semiconductor manufacturing capacity.

Past Year Trends

• Onto Innovation reported Q4 2025 net income of $10.5M ($0.21 EPS), a 78% collapse from $48.8M ($0.98 EPS) in Q4 2024, driven by GAAP gross margin compression to 46.4% from 50.2% as product mix shifted toward lower-margin systems during the advanced packaging ramp. (Bearish)
• Orders from 2.5D packaging for AI devices more than doubled year-over-year and the company secured a $240M HBM volume purchase agreement for 2026–2027, pushing Onto's backlog close to $2B — roughly double the level from three months prior. (Bullish)
• Onto Innovation announced a $710M investment for a 27% stake in X-ray metrology provider Rigaku in April 2026, targeting over $1B in addressable market expansion by combining Onto's optical metrology and AI Diffract software with Rigaku's X-ray CD-SAXS platforms, with two chip customers already selecting the new X-ray offerings ahead of closing. (Bullish)

Next Year Trends

• The Dragonfly G5 platform, qualified for 2.5D advanced packaging metrology, began initial shipments in June 2026, and its customer adoption ramp is the primary revenue lever for Onto's projected greater-than-30% advanced packaging revenue growth in FY 2026; slower-than-expected tool qualifications at TSMC or Samsung would directly compress that forecast. (Bullish)
• The Rigaku stake acquisition is expected to close in H2 2026 and be accretive by December 31, 2026, but the $710M cash outlay — large relative to Onto's ~$1B annual revenue — creates near-term balance sheet risk and integration execution risk that could distract management during the critical HBM ramp. (Bearish)
• Power semiconductor revenue, which serves automotive and industrial markets, is projected to decline approximately 10% in FY 2026, partially offsetting advanced packaging growth and creating a product-mix headwind that management must overcome to achieve its guided non-GAAP operating margin expansion to 25.5%–26.5%.
