ON Semiconductor stock has delivered a 63.1% return over the past five years, yet current checks point to a company that looks roughly in line with its estimated worth based on a Discounted Cash Flow (DCF) model, while market multiples lean on the expensive side. After a strong run into 2026 and a recent pullback, the valuation signals are mixed rather than clearly cheap or clearly stretched.
Over the last five years, ON Semiconductor has returned 63.1%, which puts recent share price weakness in the context of a longer period of value creation for shareholders.
Expectations around ON Semiconductor's role in AI data center and power semiconductor demand can support the intrinsic value case, while any slowdown in those end markets or reduced confidence in long term growth could weigh on what investors are currently willing to pay.
ON Semiconductor scores 3 out of 6 on our valuation checks, which means the broader picture is mixed rather than a clear bargain or clear overvaluation. See the full breakdown at 3 out of 6.
The issue now is whether ON Semiconductor's recent pullback has brought the stock back to a fair entry point or whether the current price still builds in too much optimism about its intrinsic value.
Find out why ON Semiconductor's 43.1% return over the last year is lagging behind its peers.
The Discounted Cash Flow (DCF) model for ON Semiconductor estimates what its future cash generation could be worth in today's dollars. The company produced last twelve month free cash flow of about $1.1b, and the model assumes that free cash flow continues to grow from this base rather than shrinking.
Based on these assumptions, the DCF points to an estimated intrinsic value of about $76 per share, which is only slightly above the current share price and indicates the stock is roughly 2.4% undervalued. Because AI data center wins and stronger reported free cash flow in recent quarters have already attracted a lot of attention, the small gap between price and intrinsic value suggests that much of this narrative is already reflected in what investors are paying today.
Overall, the DCF analysis indicates ON Semiconductor stock appears to be trading close to its estimated value based on its current cash flow profile.
ON Semiconductor is fairly valued according to our Discounted Cash Flow (DCF), but this can change at a moment's notice. Track the value in your watchlist or portfolio and be alerted on when to act.

The P/E ratio is a useful way to compare what you pay for each dollar of ON Semiconductor earnings with both the sector and direct peers. ON Semiconductor currently trades on a P/E of about 45.8x, which is almost exactly in line with the wider semiconductor industry average of 46.0x.
However, a more tailored fair P/E multiple for ON Semiconductor is estimated at 40.3x once factors such as growth profile, margins, market size and risk are taken into account. That is below the current 45.8x level and indicates that investors are paying a premium to this fair ratio, even though the stock trades at a discount to a peer group average of 92.5x.
On this P/E basis, ON Semiconductor stock appears overvalued relative to what the fair multiple suggests for its fundamentals.

ON Semiconductor looks close to its intrinsic value on a Discounted Cash Flow (DCF) basis, while the P/E view suggests the stock is overvalued relative to a tailored fair multiple. That split reflects a core tension between the cash the business is already producing and the growth expectations now embedded in the share price. With the broader checks coming out mixed, the key question from here is whether future earnings and free cash flow in areas like AI data center and power semiconductors ultimately justify the current premium that the market is willing to pay.
