Constellium SE is rated Hold due to valuation concerns, forecast volatility, and lack of dividend yield.

Recent earnings strength is driven by non-recurring items and aerospace, with core automotive and packaging segments showing only low single-digit growth.

Constellium's Packaging & Automotive Rolled Products unit posts 24% higher Q1 2026 revenues as aluminum prices stayed strong despite weaker shipments.
