CEO Claims Investors Got It Wrong on $30 Billion Shortfall as ON Stock Plummets 9%
ON Semiconductor's stock fell 9% to $66.60 during its investor day after the company reduced its total addressable market estimate by $30 billion. CEO Hassane El-Khoury attributed the change to procedural reasons, but investors reacted negatively. The company's forward P/E is near 17, while its trailing P/E is 47, leaving little room for error. The Synaptics deal is expected to close in mid-2027, and design wins in NVIDIA's MGX ecosystem are yet to translate into visible revenue.
How this was made
The 30-second read
Why it matters
The revised TAM figure and 9% price drop suggest immediate negative pressure, but the long‑term outlook hinges on design‑win execution.
Market read
ON's sharp intraday decline underscores the market's sensitivity to AI TAM revisions in the semiconductor space.
What to watch
Potential upside from automotive silicon‑carbide growth and margin improvement not fully priced yet.
Background
ON Semiconductor held an investor day to reset expectations for its power portfolio and AI data‑center opportunity.
Ticker impact
ON shares fell 9% after the investor day revealed a $30 billion lower total addressable market than previously reported.
Potential further short‑term decline toward $60‑$62 if no new wins are disclosed.
A 9% drop on the day of the event indicates strong negative sentiment; without immediate revenue visibility, traders may stay short.
Market effects
Highlights valuation risk for semiconductor firms tied to AI data‑center TAM assumptions.
US semiconductor sector may see modest pullback as investors reassess AI exposure.
Limited to investors focused on AI‑related chip makers; broader market impact minimal.
Counterpoint
If ON can quickly confirm design‑win revenue, the price could rebound sharply, making a contrarian long attractive.
