Onto Innovation (ONTO): A Record Quarter - And We Sit 34% Below The Lowest Analyst Target

Onto Innovation Inc. (ONTO) Q2 2026 — Q2 2026 (quarter ended June 30, 2026): revenue $343.1M, +35.3% y/y vs a $325.3M bar. Non-GAAP diluted EPS $1.93 vs $1.69 (+14.2%); GAAP diluted EPS $1.21 (+75%). Non-GAAP operating margin 30.0%. The May guide was $320-330M / $1.65-1.73 - the print cleared the HIGH END of all four metrics. The 8-K was accepted 4:09 p.m. ET on Aug 6, so the $268.70 close is the LAST PRE-PRINT price, not the reaction. Onto Innovation printed record revenue of $343.1M (+35.3%), non-GAAP EPS of $1.93 against a $1.69 bar, a 30.0% non-GAAP operating margin, and a backlog above $1 billion for the first time ever. It then guided Q3 revenue to $380-400M against a $351.8M consensus and EPS to $2.18-2.38 against $1.93. This was an excellent quarter and we say so repeatedly. Our disagreement is entirely about price. We build an owner-earnings DCF with ONE cyclical down year in five - the observed history of this industry and of this company, whose revenue fell 14% in a single quarter twelve months ago and which earned a 5.2% operating margin two quarters ago. That model says $190. Probability-weighted with a no-down-year bull case at $271 and a 2028-rollover bear case at $120, fair value is about $208 against the $268.70 pre-print close. The bull case is essentially today's price. THE CALL: HOLD (3/5, AN ELITE QUARTER AT A PRICE THAT ASSUMES THE CYCLE NEVER TURNS AGAIN) — base-case value ~$208.0 vs ~$268.7 today. KEY METRICS: - CALL: HOLD 3/5, fair value ~$208 vs the $268.70 pre-print close (-23%). Bull $271, base $190, bear $120.
