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

A Discounted Cash Flow, or DCF, model estimates what a company could be worth by projecting future cash flows and then discounting them back to today using an appropriate rate. It is essentially asking what all those future cash flows are worth in present dollar terms.

For ON Semiconductor, the model used is a 2 Stage Free Cash Flow to Equity approach. The latest twelve month Free Cash Flow is about $1.04b. Analysts and extrapolations together project Free Cash Flow reaching $2.32b by 2030, with a series of annual figures between 2026 and 2035 that are discounted back to present value. Simply Wall St uses analyst estimates for the earlier years and then extends those cash flows using its own assumptions for the outer years.

Putting those projected cash flows together, the DCF model arrives at an estimated intrinsic value of US$68.82 per share for ON Semiconductor, compared with the recent share price of about US$83. Based on these inputs, the stock appears around 20.6% overvalued.

Result: OVERVALUED

Our Discounted Cash Flow (DCF) analysis suggests ON Semiconductor may be overvalued by 20.6%. Discover 59 high quality undervalued stocks or create your own screener to find better value opportunities.

Approach 2: ON Semiconductor Price vs Sales

For profitable companies that are already generating meaningful revenue, the P/S ratio is a useful sense check because it links what you pay in the market to each dollar of sales the business produces.

What counts as a reasonable P/S ratio depends in part on how quickly revenue is expected to grow and how risky those future cash flows appear. Higher growth or lower perceived risk can justify paying a higher multiple, while slower growth or higher uncertainty tends to point to a lower, more conservative range.

ON Semiconductor is trading on a P/S of 5.45x. This is below the Semiconductor industry average of 6.53x and below the peer group average of 15.29x. Simply Wall St also calculates a proprietary “Fair Ratio” of 4.22x for ON Semiconductor, which is the P/S level suggested by factors such as its earnings growth profile, industry, profit margins, market capitalization and company specific risks.

This Fair Ratio can be more informative than a simple comparison with peers or the broad industry because it adjusts for those company level characteristics rather than assuming one size fits all. Compared with the current P/S of 5.45x, the Fair Ratio of 4.22x indicates that ON Semiconductor appears overvalued on this measure.

Result: OVERVALUED
