- ON Semiconductor closed down 9.02% at $66.60 on the day of its investor day, extending a one-month drawdown of 20.12% even as the year-to-date return stayed positive at 22.99%.
- The selloff followed a $30 billion reduction in the total addressable market shown on stage: $213 billion versus the $243 billion figure the company cited in June when it announced the Synaptics acquisition.
- CEO Hassane El-Khoury attributed the smaller TAM to procedural requirements, saying the presentation focused on the core onsemi business because acquirer and target run independently until the Synaptics deal closes, expected in mid-2027.
- Investors questioned the AI data center growth assumptions, seeking more than assertions from design wins, including expanded content in the NVIDIA MGX ecosystem, two power-supply platform wins with Great Wall in China, and AWS power-supply and battery-backup content in the United States.
- El-Khoury framed the AI data center assumption as prudent, anchoring to a 30% market in the middle of the range and adding a 10-point outgrowth claim that is testable only through design-win revenue.
- The 53% gross margin target requires a mix shift toward silicon carbide, gallium nitride, and Treo analog content, with Q2 non-GAAP gross margin at 39.3% and management's sensitivity of 25 to 30 basis points of gross-margin improvement for every point of utilization.
- The Analog and Mixed-Signal segment was down 2% year over year in the most recent quarter, and El-Khoury deflected the near-term comparison by citing 72% automotive revenue growth from 2019 to 2026.
