Price $77.36 · Downside -48.0%
Model ⓘEach model values the company its own way (discounted cash flow, earnings, assets, dividends). The fair value above starts from their evidence-weighted blend, not from a single model. In cyclical trough or peak years, after dilution or a stock split it is adjusted afterwards, so it can sit above or below the models. Based on fiscal year 2025 figures (about 10 months old). Earnings retained since then ($2.14 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.Coverage ⓘCoverage = 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.

Growth Quality ⓘGrowth is valuable only when reinvestment earns attractive returns (Aswath Damodaran): sustainable growth depends on return on capital, reinvestment and efficiency.

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. Basis: adjusted.

Growth Forecast
Price in line with expectations
The price assumes more growth than the company has delivered so far and about what 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).
+18.7%
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.
+18.0%
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 +16.0% a year for the price and +15.3% for the forecasts.
News mood ⓘNews mood, the average tone of recent news (96 articles), rated against how stocks are usually covered. 🚀 Hype = unusually upbeat · 🙂 Positive = above average · 😐 Neutral = typical · 🙁 Negative = below average · 😨 Very negative = unusually downbeat. It reflects the tone of coverage, not our valuation.Hype
Recent news coverage is unusually upbeat, far more positive than stocks are typically covered.
AI conclusion: Diodes' acquisition of ElevATE to enter higher-margin analog and mixed-signal products for test equipment forms its main strength, while thin public evidence and weak profitability metrics point to limited durable advantage as the key weakness.
Main risk: Integration risks from the ElevATE acquisition could prevent the expected margin improvements in analog and mixed-signal products from materialising.
Diodes has completed its acquisition of ElevATE Semiconductor to expand into higher-margin analog and mixed-signal products for the automated test equipment market. This follows strong second-quarter revenue growth driven by automotive, computing including AI data centers, and industrial demand. Will the promised margin lift from the new portfolio outweigh integration risks and deliver lasting improvement?

Excluding one-off items of fiscal year 2025 it is 63.4 (reported for FY2025: 54.1). Median P/E at fiscal year-end, 10 fiscal years (2016 to 2025), reported earnings, 8 of the years ex one-offs: 31.2.
