Also worth knowing about ON

“Increasing power requirements are driving accelerated demand in our AI data center and industrial end markets, as customers adopt and ramp our differentiated products”
— Hassane El-Khoury, President and CEO of onsemi · SEC filing
From the company's earnings release filed with the SEC on 2026-11-02 (Form 8-K).
What would change the picture for ON
These are the specific events and levels to watch. None of them is a prediction.
Insider buying: none on the open market in 90 days. A purchase by an executive or director would be the first in at least three months, and it would show up on SEC Form 4 within two business days.
Price levels: a close above $133.93 would be a new 52-week high, 91.0% above the latest close of $70.11; a close below $44.9 would be a new 52-week low, 36.0% below it.
Growth: revenue rose 2.9% year over year in the quarter ending Oct 2026 (trend: accelerating). At a P/E of 41.0, a slowdown would matter more than at a lower multiple.
New shares: dilution risk is moderate now. A new shelf registration (S-3) or a prospectus supplement (424B) for an offering would raise it.
