Onto Innovation Inc. Common Stock (ONTO) : juste valeur

Thèse ACCE

Onto Innovation makes process-control metrology and inspection systems that chipmakers use to catch defects in advanced packaging, lithography and patterning steps, and it has a sizable installed base that generates recurring service and software revenue. Its moat rests on that installed base and on the difficulty of qualifying a competitor's tools into a fab line, which gives it pricing power in a niche where a single yield problem can cost a customer far more than the equipment. The near-term driver is the build-out of advanced packaging and high-bandwidth memory, where tighter tolerances make inspection more necessary per wafer, and revenue growth of 35.3% shows that demand is already flowing through. At 22.5 times forward earnings against a trailing multiple of 99.1, the market is pricing a sharp earnings recovery, and the 23.0% operating margin suggests the business can convert that growth into profit if the cycle holds. The 6.8% return on equity is thin for a company of this quality, so the thesis depends on margin expansion rather than balance-sheet efficiency, which is the first thing to test.
