Valuation
Bull case: the Growth DCF group reads highest at a median of $38.08 per share, and 0 of the 24 models we run sit above the $83.40 price.
Bear case: the Growth Earnings group reads lowest at $4.88, and 24 of the 24 models stay below the price. Evidence for this calculation is high.
Scenario range: $16.30 (bear) to $18.91 (bull), the price of $83.40 sits above it. Bear and bull are the same models on cautious and optimistic assumptions, a range, not a price target.
Quality & growth
The Quality Score stands at 64/100 (solid quality).
Weak Growth: Revenue growth is inconsistent: the periods point in different directions, so there is no trend to rely on.
ON Semiconductor Corporation reported revenue of $6.0B in FY2025 versus $6.7B in FY2021, a compound −2.9%/yr. Reported net income was $121M in FY2025, compounding −41.2%/yr from FY2021.

Fair Value models
Bear $16.30
Fair Value $17.61
Bull $18.91
Model ⓘEach model values the company its own way (discounted cash flow, earnings, assets, dividends). The fair value above is their evidence-weighted blend, not the output of a single model. Based on fiscal year 2025 figures (about 9 months old). Earnings retained since then ($2.46 per share) are deliberately not added.
Bear ⓘBear = the cautious scenario: the same model computed with conservative anchors (lower growth, margins and valuation multiples). Together with Bull it frames a plausible valuation range, not a price target.BaseBull ⓘBull = the optimistic scenario: the same model computed with favourable anchors (higher growth, margins and valuation multiples). Together with Bear it frames a plausible valuation range, not a price target. If a model's bull case is above four times its base value, the table shows that limit with a > sign (like the overall Bull above): beyond it no assumption holds.
Evidence ⓘEvidence = how well-backed THIS model's estimate is for this stock (0–100): how complete and reliable its input data are, and how well the model fits the company. The final Fair Value is an evidence-weighted blend, so better-evidenced models count more. Green ≥70, amber 50–69, grey below 50.

Revenue & earnings trend
Growth Quality ⓘGrowth is valuable only when reinvestment earns attractive returns (Aswath Damodaran): sustainable growth depends on return on capital, reinvestment and efficiency. Basis: total company revenue over the periods shown on the cards (3Y/5Y/all years), not per share, so a merger can show up as a growth jump; per-share earnings growth is in the value-creation card.
40/100
Revenue growth is inconsistent: the periods point in different directions, so there is no trend to rely on.
Revenue growth 1 year
−15.3%
Revenue growth 3 years ⓘMeasures the company's TOTAL revenue from reported annual statements: compound average growth per year (CAGR) from the fiscal year 3, 5 or N years back to the most recent comparable fiscal year. Not per share: buybacks do not change this number, and a merger can appear as a growth jump. Per-share growth (which does include buybacks) is in the value-creation card.
−10.4%
Revenue growth 5 years ⓘMeasures the company's TOTAL revenue from reported annual statements: compound average growth per year (CAGR) from the fiscal year 3, 5 or N years back to the most recent comparable fiscal year. Not per share: buybacks do not change this number, and a merger can appear as a growth jump. Per-share growth (which does include buybacks) is in the value-creation card.

What shareholders gained per year (last 5 years) ⓘWhat the business itself delivers per year: earnings growth per share plus the dividend yield. This is what you get IF the market keeps valuing the stock the same way: it contains no assumption about the market changing its mind. Computed per share, so buybacks count and a merger does not pass as growth. For a company that pays no dividend it is pure earnings growth per share. Period: earnings growth per share as CAGR over the last 5 reported fiscal years (annual statements), plus the current dividend yield. The start value is the median of the three years around the start, so a single crisis year (a pandemic or a write-down) does not distort the rate.
−12.1%
Earnings growth per share plus dividend.
Earnings per share, growth per year−12.1%
Dividend (yield on the price)0.0%
Pace: 5 vs 10 years ⓘTwo data points, not a trend model: earnings growth per share over the last 5 fiscal years against the last 10. Labelled "steady" when both rates are within 3 percentage points of each other, otherwise picking up or flattening. Shown only when ten years of history exist.−12.1% vs −3.8%, slowing
Profit margin 2020 to 2025 ⓘOperating margin then vs now, from reported annual statements. A falling margin after a boom year is the classic peak-earnings signal: the growth rate then leans on an inflated base.8% → 13%
Start year 2020 (pandemic)
Growth Forecast
A lot of optimism in the price
The price assumes more growth than the company has delivered so far and more than analysts expect.
What the price assumes ⓘThis turns our valuation around: instead of asking what the share is worth, it asks what growth the current price requires. It uses the cash the company keeps after all spending (free cash flow), the same discount rate as our models, five years of growth, then slowing evenly to 2 % a year by year ten. Compared with the analysts' sales forecasts extended to the same five years (at least three analysts, for context only, it does not enter the Fair Value): within 3 percentage points counts as "in line" (amber), below that little optimism (green), above that a lot of optimism (red).
+19.0%
Yearly growth needed for the next five years to justify today's price.
What forecasts expect ⓘAnalysts publish sales forecasts for the next two fiscal years. For the years after that, growth slows evenly to 2 % a year by year ten (2 % is the long-run rate our models use). Projected years are marked as such.
+9.3%
Yearly sales growth analysts expect, extended to five years.
After inflation (USA: IMF forecast 2.4% a year to 2030, 3.1% from 2016 to 2025) that is about +16.2% a year for the price and +6.8% for the forecasts.
Forecast 2026 (sales)+8.2%
Forecast 2027 (sales)+11.4%
Projected 2028 (sales)+10.2%
Projected 2029 (sales)+9.0%
Projected 2030 (sales)+7.9%

What is a reverse DCF?
A reverse DCF turns the usual calculation around. Instead of deriving a value from assumptions, it takes today's price as given and asks: what free-cash-flow growth would a company have to deliver for exactly this price to be fair? The result is not a forecast but the expectation already priced in. For ON Semiconductor Corporation that is +19.0 % per year a year over ten years, using the same discount rate (12.8 %) and the same formula as our fair value.
How much growth has ON Semiconductor Corporation (0KC4) delivered so far?
