Constellium is up nearly 83% YTD, driven by strong aluminum pricing and robust end-market demand for engineered products. I initiate coverage with a Buy rating, expecting a material Q2 earnings beat fueled by shipment growth, improved pricing, and margin expansion. CSTM trades at a discounted 10.4x forward earnings and 6.8x EV/EBITDA, despite superior value-added positioning versus peers.
