What Onto Innovation does
Onto Innovation, headquartered in Wilmington, Massachusetts and with roots going back to 1940, supplies process control tools to the semiconductor industry. Its portfolio covers optical metrology, macro-defect and wafer all-surface inspection, transparent and opaque thin film measurement, automated defect classification, and lithography systems for advanced packaging. These are sold as standalone and integrated systems and backed by process control software that can run a single tool, a group of tools, or a whole factory. Its customers include semiconductor and advanced packaging device makers, silicon wafer producers and IC fabs, along with makers of LEDs, VCSELs, MEMS, CMOS image sensors, power, analog and RF devices, and data storage products. Revenue comes from system sales, software licensing, spare parts and services. Its customers are spread across the United States, Taiwan, South Korea, Japan, China, Southeast Asia and Europe.

What is Onto Innovation worth?
On an owner-earnings DCF, Onto Innovation's most-likely value is about $161 versus a recent price near $295 (45% above fair value). But TacticScale only calls a stock undervalued when the price sits below its conservative no-growth floor (~$58) with a margin of safety — so the honest verdict here is “Fairly priced — no edge.” Fair value earns its keep only at the extremes, not in the wide middle.
Price sits in the normal range — fair value isn't actionable here; it earns its keep only when price drops below the no-growth floor, or runs to roughly double the optimistic case.
Analysis, not advice. Fair value is a margin-of-safety estimate from a deterministic owner-earnings DCF, not a price target or recommendation. See the full breakdown →
