Constellium SE CSTM continues to benefit from strength in its Aerospace & Transportation (A&T) segment. The segment’s shipments increased 18% to 60 thousand metric tons in the first quarter of 2026. The results were driven by higher shipments of aerospace and transportation, industry and defense (TID) rolled products.
Shipments also benefited from ongoing supply shortages of automotive rolled products in North America. Also, revenues from the segment increased 30% to nearly $609 million in the quarter, supported by strong shipments and metal prices.
Rising aluminum prices have been providing support to domestic producers like Constellium. Geopolitical tensions between Israel and Iran have heightened concerns over potential disruptions in the Strait of Hormuz, a key global shipping route, leading to tighter supply conditions. Consequently, higher aluminum prices are benefiting major industry participants, including Constellium.
Also, in the first quarter, the company’s adjusted EBITDA increased 24% year over year to $102 million. The growth was driven by higher shipment volumes and favorable foreign exchange impacts. However, these gains were partly offset by an unfavorable price and product mix, along with higher operating costs due to increased business activity.
Constellium’s A&T segment remains well-positioned, supported by healthy aerospace demand, strong industry and defense shipments, and favorable aluminum pricing trends. Continued strength in these end markets, along with disciplined execution, should support the segment’s performance in the quarters ahead.
