Fair Value models

Price €14.94 · Downside -55.0%
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.

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.59/100
Revenue is growing, but margins or cash flow do not fully confirm the trend.
Profit margin (trend) ⓘ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.

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).
+22.4%
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.
+10.2%
Yearly sales growth analysts expect, extended to five years.
After inflation (euro area: IMF forecast 2.2% a year to 2030, 2.6% from 2016 to 2025) that is about +19.8% a year for the price and +7.9% for the forecasts.
News mood ⓘNews mood, the average tone of recent news (71 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.Positive
Recent news coverage is more positive than average.
AI conclusion: Acerinox draws its main strength from consistently outperforming North American stainless steel operations while its main weakness remains the loss-making European business with high leverage and thin moat evidence.
Main risk: Any slowdown in the North American stainless steel operations would expose the entire group to margin pressure from European cyclicality and high leverage.
Acerinox generates most of its earnings and enterprise value from its North American stainless steel operations, which have consistently outperformed the European side. Europe shows signs of recovery through higher volumes and policy support, yet remains a smaller contributor. Our models view the shares as overvalued. Will the US business continue to offset European cyclicality or will any slowdown there expose the full group to margin pressure?

The payout ratio is 117% of earnings. Free cash flow covers the dividend 0.98 times. Our assessment: Payout strained. The dividend exceeds reported earnings (though reported profit is often depressed by one-off charges), and free cash flow only just covers it (or coverage is unknown). Not an emergency, but little room for error.
What growth is priced into Acerinox (ACX)?

Our models discount Acerinox at 11.1 %: a base by market capitalisation (mid), damped by beta 1.01, country premium for Spain. The same rate applies in all 26 models.
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 Acerinox that is +22.4 % per year for five years, then slowing evenly to 2 % by year ten, using the same discount rate (11.1 %) and the same formula as our fair value.
How much growth has Acerinox (ACX) delivered so far?
Over the past 5 years revenue at Acerinox grew +4.4 % a year. The price currently implies free-cash-flow growth of +22.4 % per year. Comparing the two shows how much confidence is in the price: if it demands more than has been delivered, the business has to accelerate for the maths to work.

What is the free cash flow yield of Acerinox (ACX)?
The free-cash-flow yield on the price is 4.04 %: that much free cash flow Acerinox produces per unit of market value. When it exceeds the discount rate of our models (11.1 %), the business already earns more than its cost of capital demands, and the price needs little additional growth.
What is the intrinsic value of Acerinox (ACX)?
Intrinsic value and fair value mean the same thing: what the business is worth on its numbers, independent of the share price. For Acerinox it is €6.72 per share (as of Nov 5, 2026), against a price of €14.94. It is the blended result of 13 valuation models in 6 families (DCF Models, Earnings-Based, Multiples, Asset-Based, Growth DCF, Economic Profit).

What is the P/E ratio of ACX?
Acerinox trades at a price-to-earnings ratio of 28.2 (as of Nov 5, 2026). A P/E on its own says little: it compares the price with ONE year of profit, while our fair value of €6.72 is built from several models across several years. Median P/E at fiscal year-end, 8 fiscal years (2016 to 2024), reported earnings: 11.1. Other multiples: PEG 0.4, P/B 1.8, P/S 0.6, EV/EBITDA 8.4.
