Constellium stock has delivered a strong 117.2% return over the past year, while both the Discounted Cash Flow (DCF) intrinsic value estimate and earnings based multiples currently point to the shares trading below what those frameworks suggest as fair value.

• Over the last 12 months, Constellium has returned 117.2%, which puts more focus on whether the recent share price better reflects its fundamentals.
• Constellium's new 10 year local solar power agreement in Germany can support long term energy cost visibility and margins. However, execution risks around large decarbonisation and efficiency projects may still influence future cash flows.
• On Simply Wall St's broader checks, Constellium screens as undervalued in 6 of 6 valuation tests, which leans toward the shares looking cheap across several methods rather than just a single metric.

The issue now is whether Constellium's current price already reflects this apparent discount, or if the stock still offers room before it converges toward the intrinsic value estimate.

Is Constellium Still Cheap on Cash Flow?

The Discounted Cash Flow (DCF) model estimates what Constellium is worth today based on the cash it is expected to generate in the future. For Constellium, the latest twelve month free cash flow sits at about $91.5 million, with the model assuming that cash flows grow from this base rather than staying flat or shrinking.

On those projections, the 2 Stage Free Cash Flow to Equity model points to an intrinsic value of about $48.81 per share, which implies the stock trades at a 38.5% discount to that estimate. Because the new 10 year local solar power agreement in Germany can improve long term cost visibility, yet still carries execution risk, the ongoing market discount may partly reflect how investors weigh those future cash flow uncertainties.

Overall, the DCF output indicates that, based on these projections, Constellium stock appears undervalued relative to its projected cash generation.

Is Constellium Still Cheap on Earnings?

The P/E ratio is a useful cross check for Constellium because it ties the current share price directly to the earnings that equity holders are paying for today. Constellium trades on a P/E of about 9.4x, which sits below the Metals and Mining industry average of roughly 16.2x and also below the peer group average of around 11.2x.

On Simply Wall St's model, a more tailored fair P/E for Constellium that reflects its profile is about 14.1x. Compared with the current 9.4x, this gap indicates that the market is assigning a discount relative to what that framework suggests investors might typically pay for similar earnings. While the share price has already moved sharply over the past year, the earnings multiple still indicates that Constellium stock is priced below that modelled benchmark.

Overall, the P/E comparison indicates that Constellium appears undervalued on its earnings multiple.

The Bottom Line

For Constellium, both the Discounted Cash Flow (DCF) intrinsic value estimate and the earnings multiple work in the same direction, pointing to a stock that still screens as undervalued rather than fully priced. The key question is whether the current discount reflects lingering concerns about execution on long term projects, including decarbonisation and energy efficiency plans, or whether the market is being overly cautious. From here, the crux of the debate is whether Constellium can deliver the cash flows and margins implied in the intrinsic value models, which would make the present discount look like an opportunity rather than a warning sign.
