Onto Innovation is back in focus after Simply Wall St linked a warning from SK Hynix about a prolonged artificial-intelligence memory shortage to demand for Onto's defect-prevention and metrology tools on high-bandwidth-memory production lines. The analysis was published on October 29, 2026.

AI memory thesis faces valuation test

The article's central narrative placed fair value at USD 380 against a last close of USD 223.68 and described Onto Innovation as potentially undervalued. It also argued that investors may still view the company mainly as a cyclical semiconductor-equipment supplier rather than as an AI-infrastructure beneficiary.

That bullish framing came with material qualifications. Simply Wall St pointed to weaker semiconductor capital spending and the possibility that a rival could match Onto's advanced-packaging metrology capabilities. Its valuation discussion also cited a price-to-earnings ratio of 82.8 times, compared with 45.2 times for the US semiconductor industry and a stated fair ratio of 44.6 times.
