Price €55.00 · Upside +104.0%
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. 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.

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. 4/100

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.

Recent news coverage is unusually downbeat.
Note from the team Nov 10, 2026
AI conclusion: Limited durable moat and weak margins mark Siltronic's business quality, with rising AI wafer demand as the main strength against persistent cost pressures from expansion.
Main risk: Higher depreciation from the Singapore capacity build-out risks continuing to weigh on earnings even as AI-related wafer volumes increase.
Siltronic lifted its 2026 sales guidance after Q3 volumes rose on stronger demand for 300 mm wafers, especially those supporting artificial intelligence applications. Higher depreciation from the Singapore capacity build-out still weighs on earnings despite the volume gains and better currency effects. With our models seeing the stock as undervalued, does the business capture more lasting benefit from AI wafer demand than it faces in persistent cost and product-mix pressures?

The market is more pessimistic than our downside scenario. The large gap to fair value rests on thin data (low evidence): fewer applicable models and a shorter history. Read it with extra caution. A fairly wide model range (€76.66 to €147.69) leaves room in how you read the outcome.
