Approach 1: ON Semiconductor Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow, or DCF, model estimates what a stock could be worth by projecting the cash the company may generate in the future and then discounting those amounts back to today in $ terms.

For ON Semiconductor, the model used here is a 2 Stage Free Cash Flow to Equity approach. The latest twelve month free cash flow is reported at about $744.7m. Analyst based and extrapolated forecasts used by Simply Wall St project free cash flow rising to $2,581.2m by 2030, with ten year projections sourced from a mix of analyst estimates and gradual growth assumptions after those analyst horizons.

Discounting those projected cash flows back to today gives an estimated intrinsic value of about $73.16 per share. Compared with the current share price of around $109.61, the DCF output suggests the stock is trading at a premium, with the model indicating ON Semiconductor is about 49.8% overvalued on this basis.

Result: OVERVALUED

Approach 2: ON Semiconductor Price vs Earnings

For profitable companies, the P/E ratio is a useful shorthand because it links what you are paying directly to the earnings the business is currently generating. It lets you compare how the market prices one dollar of earnings across different stocks.

What counts as a “normal” P/E depends a lot on growth expectations and risk. Higher expected growth or lower perceived risk can justify a higher P/E, while lower growth or higher risk usually points to a lower one.

ON Semiconductor currently trades on a P/E of 74.88x. This sits above the Semiconductor industry average of 63.57x and below the peer group average of 101.20x. Simply Wall St also calculates a proprietary “Fair Ratio” for ON Semiconductor of 49.41x.

The Fair Ratio is designed to go further than a simple peer or industry comparison. It adjusts the preferred multiple for factors specific to the company such as its earnings growth profile, profit margins, industry, market capitalization and key risks, which can make it a more tailored benchmark.

Comparing ON Semiconductor’s current P/E of 74.88x with the Fair Ratio of 49.41x suggests the stock is trading above this company specific benchmark.

Upgrade Your Decision Making: Choose your ON Semiconductor Narrative

Earlier it was mentioned that there is an even better way to understand valuation, so Narratives are introduced here as simple stories you choose about ON Semiconductor that connect your own view of its future revenue, earnings and margins to a specific fair value. You can then compare that fair value with the current price to help you decide what action, if any, makes sense.

On Simply Wall St's Community page, Narratives are presented as easy to use setups where you pick or adjust a forecast and instantly see how that storyline flows through to valuation. This valuation is then refreshed when new information such as earnings, guidance, partnerships or buyback updates is added to the platform.

For example, one ON Semiconductor Narrative on the more cautious side might lean toward a fair value around US$68.28 or US$73.15 based on moderate revenue growth and margins. A more optimistic Narrative could lean toward a higher fair value such as US$78.63. By seeing these side by side you can decide which story aligns more closely with your own expectations for the stock before comparing any of them with the latest share price.
