• If you are wondering whether Constellium's current share price still represents value, the recent numbers give plenty to think about before making any decisions.
• The stock last closed at US$34.26, with returns of 3.1% over 7 days, 6.3% over 30 days, 73.3% year to date, 182.2% over 1 year, 114.9% over 3 years, and 91.6% over 5 years. This puts recent gains and longer term performance firmly on your radar when assessing risk and reward.
• Recent headlines around Constellium have focused on the stock's strong share price performance and investor interest in the materials sector, which helps explain why it has been so closely watched. This context is useful when thinking about how much optimism may already be reflected in the current share price.
• Constellium currently has a valuation score of 5/6. The rest of this article will unpack what that means using different valuation approaches, with an even clearer way to think about value waiting at the end.

Approach 1: Constellium Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow model estimates what a stock might be worth by projecting the company’s future cash flows and discounting them back to today’s value in $.

For Constellium, the model uses a 2 Stage Free Cash Flow to Equity approach. The latest twelve month Free Cash Flow is about $91.5 million. Analysts provide Free Cash Flow estimates out to 2028, and Simply Wall St extrapolates further to build a 10 year view. By 2035, the model uses projected Free Cash Flow of $661.7 million, with each future year discounted back to reflect time and risk.

Combining these discounted cash flows gives an estimated intrinsic value of about $49.13 per share, compared with the recent share price of $34.26. That gap implies the stock trades at roughly a 30.3% discount to this DCF estimate.

This model suggests the current price leaves a margin between what you pay and what the cash flow stream is worth under these assumptions.

Result: UNDERVALUED

Our Discounted Cash Flow (DCF) analysis suggests Constellium is undervalued by 30.3%. Track this in your watchlist or portfolio, or discover 46 more high quality undervalued stocks.

Approach 2: Constellium Price vs Earnings (P/E)

For a profitable company, the P/E ratio is a useful way to think about value because it links what you pay for each share to the earnings that share currently generates. Higher growth expectations and lower perceived risk usually justify a higher P/E, while slower growth or higher risk typically point to a lower, more cautious range.

Constellium trades on a P/E of 10.72x. That sits below the Metals and Mining industry average P/E of 19.95x and the peer group average of 16.82x. This puts the stock at a lower earnings multiple than these broad benchmarks. Simply Wall St also calculates a Fair Ratio of 14.32x, which is the P/E you might expect when factoring in the company’s earnings growth profile, profit margins, industry, market cap and key risks.

This Fair Ratio can be more informative than a plain comparison with peers or the industry because it adjusts for Constellium’s own characteristics rather than assuming all companies deserve similar multiples. With the current P/E of 10.72x sitting below the Fair Ratio of 14.32x, this approach suggests that the stock is priced below the level implied by those fundamentals.

Result: UNDERVALUED

Upgrade Your Decision Making: Choose your Constellium Narrative

Earlier it was mentioned that there is an even better way to understand valuation. This is where Narratives come in, giving you a simple way to attach a story about Constellium to the numbers you use for fair value, revenue, earnings and margins so that your view on the company is explicitly linked to a forecast and then to a fair value that can be compared with the current price.

On Simply Wall St’s Community page, Narratives are an easy tool that millions of investors use to do exactly this. Each Narrative updates automatically when new information such as earnings or news is added, so your story and numbers stay aligned without extra work.

For Constellium, one investor might build a Narrative that leans closer to the more optimistic fair value of about US$40.00, using assumptions similar to the bullish cohort. Another might anchor their Narrative near the more cautious fair value of about US$34.13. By comparing each Narrative’s Fair Value with the current price, both investors can decide whether the stock looks attractive, fully priced, or expensive according to their own assumptions rather than relying only on a single P/E or DCF output.

For Constellium, however, we will make it really easy for you with previews of two leading Constellium Narratives:

Fair value in this bullish Narrative: US$40.00 per share.

Implied discount vs last close: about 14.3% below this fair value.

Revenue growth assumption: 8.13% per year.

• Focuses on higher revenue growth supported by local production, recycling and sustainability themes in automotive, aerospace and renewables.
• Uses bullish analyst assumptions on earnings, margins and a higher future P/E multiple to support a US$40.00 fair value.
• Flags risks around tariffs, sector demand weakness, cost pressures and leverage that could challenge cash flow and margins.

Fair value in this more cautious Narrative: US$34.00 per share.

Implied premium vs last close: about 0.8% above this fair value.

Revenue growth assumption: 9.35% per year.

• Sees Constellium as a value oriented materials stock with exposure to aerospace, packaging, automotive and recycling, but still tied closely to industrial cycles.
• Highlights solid recent revenue, EBITDA, earnings and free cash flow figures, alongside management targets under the Vision 2028 framework and a sizeable buyback program.
• Emphasizes risks such as cyclicality, leverage, input and energy costs, the quality of recent earnings and execution on longer term goals, which could limit valuation upside.

If you want to go beyond these previews and build your own view based on the assumptions you find most realistic, the full Narratives on Simply Wall St let you adjust growth, margins and valuation multiples so the fair value you use for Constellium matches your own expectations, not just a single model outcome.
