ON Semiconductor (ON) is back in focus after better than expected first quarter results, upbeat guidance for AI data center revenue growth, and early signs of recovery in its automotive business.

The stock has been volatile around the recent earnings beat and $1.3b zero coupon convertible notes, but the 30 day share price return of 36.26% and 1 year total shareholder return of 151.80% indicate strong recent momentum.

With the stock now around US$113, recent returns in triple digits over 1 year, and analysts’ average target sitting below the current price, the key question is simple: is there still a buying opportunity here, or is the market already pricing in future growth?

Most Popular Narrative: 66% Overvalued

The most followed narrative currently places ON Semiconductor’s fair value at $68.28, well below the recent close at $113.11, framing a cautious valuation gap.

The company's strategic investments in silicon carbide (SiC), wide bandgap technologies, and advanced power management solutions for both automotive and AI data centers position it at the forefront of key structural growth markets; as these high-value products ramp, they are expected to enhance margins and drive long-term earnings growth.

Curious what earnings path and margin profile support that fair value, given today’s elevated share price and strong recent returns? The narrative leans on compounded earnings expansion, richer profitability, and a future valuation multiple that looks very different from where the stock trades now.

Result: Fair Value of $68.28 (OVERVALUED)

However, this upbeat story still bumps up against real pressure points, including underused manufacturing capacity and heavy reliance on cyclical auto and EV demand continuing as expected.
