Constellium (CSTM) Stock May Be 12% Undervalued On Cash Flow

Simply Wall St·09/18/2026 14:28:28
Listen to the news

Constellium has put in a strong run over the past year, and the real question now is whether the current share price lines up with the cash flows the business is expected to generate. With the stock recently closing at US$26.19, investors are increasingly focused on what the company’s cash generation can reasonably support over time.

  • The share price is up 60.1% over the past year, which puts the spotlight on whether that move is grounded in the cash the business can produce.
  • The investment story leans heavily on how efficiently Constellium can convert its operations into steady free cash flow, which may support or constrain what you are willing to pay today.
  • If you'd rather focus on earnings, this one's for you. See what Constellium's 6.5x P/E says about the price.

The stock's next move may depend on whether that recent price level is justified by the intrinsic value suggested by its cash flows.

Is Constellium Still Cheap on Cash Flow?

The Discounted Cash Flow (DCF) approach here focuses on what Constellium can return to shareholders in pure cash over time. Latest twelve month free cash flow sits at about $117.8m, which is not especially large for a listed industrial group, so the model leans heavily on how future cash generation develops from this base.

The projections used in the DCF assume free cash flow grows from current levels into the coming decade rather than shrinking away. That future profile produces an estimated intrinsic value that the model places modestly above the recent trading level of US$26.19, suggesting the stock price does not fully reflect the projected stream of cash the business is expected to produce.
