Approach 1: Constellium Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow, or DCF, model takes estimates of the cash a company could generate in the future and discounts those amounts back to today, to arrive at an estimate of what the whole business might be worth right now.

For Constellium, the model used is a 2 Stage Free Cash Flow to Equity approach, based on cash flow projections in US$. The latest twelve month free cash flow is reported at about $91.5 million. Analyst estimates and extrapolated figures in this model point to projected free cash flow of $417.3 million in 2028, with a series of annual projections between 2026 and 2035 that are discounted back to today to reflect risk and the time value of money.

Combining these discounted projections in this model results in an estimated intrinsic value of about $49.33 per share. Against the recent share price of around $32.87, this model suggests the stock is approximately 33.4% undervalued.

Result: UNDERVALUED

Approach 2: Constellium Price vs Earnings

For profitable companies, the P/E ratio is a useful shorthand because it links what you pay for the stock to the earnings the business is currently generating. A higher or lower P/E often reflects what the market is factoring in for future earnings growth and the risk investors see in those earnings.

Constellium currently trades on a P/E of about 10.3x. That sits well below the Metals and Mining industry average P/E of 19.4x and the peer group average of 49.8x. On the surface, that gap can look like a discount, but simple comparisons to peers do not account for differences in growth, profitability, size or risk.

Simply Wall St’s Fair Ratio helps with that by estimating what a more suitable P/E might be once factors such as earnings growth, industry, profit margins, market cap and company specific risks are considered together. For Constellium, this Fair Ratio is 14.1x, which is higher than the current P/E of 10.3x. On this basis, the stock screens as undervalued relative to what the Fair Ratio suggests could be a more appropriate earnings multiple.

Result: UNDERVALUED
