Constellium (CSTM) is back in the spotlight after reporting fourth quarter and full year 2025 results, with sales of US$2,201 million in the quarter and a shift from a net loss to net income.

The strong quarterly and full year results, together with the recently completed share buyback and sustainability update, come after a powerful run in the shares, with a 30.65% year to date share price return and a very large 153.98% total shareholder return over the past year. This suggests momentum has been building despite a 0.88% pullback in the last session.

Most Popular Narrative: 10.7% Undervalued

Constellium’s most followed valuation narrative pegs fair value at about $28.92, a touch above the last close of $25.83, framing the recent share move in a wider context.

Analysts have raised their blended price target on Constellium from about $20.12 to roughly $28.92, citing Q4 earnings beats, stronger free cash flow trends that may support deleveraging and buybacks, and revised forward P/E assumptions in the low teens.

Curious what sits behind that higher fair value range? The story leans heavily on free cash flow, share count changes, and an earnings profile that assumes a different future multiple. The exact mix of growth, margins, and discount rate might surprise you.

Result: Fair Value of $28.92 (UNDERVALUED)

However, the story can change quickly if demand in key markets like automotive and aerospace stays weak, or if higher energy and labor costs squeeze margins.
