Constellium SE CSTM is poised to gain from solid momentum in its Aerospace & Transportation (A&T) segment. The segment’s shipments surged 18% to 60 thousand metric tons in the first quarter of 2026. Higher shipments of aerospace and transportation, industry and defense (TID) rolled products aided the segment.
Ongoing supply shortages of automotive rolled products in North America benefited shipments as well. Revenues from the segment also rose 30% to approximately $609 million in the quarter, supported by strong shipments and metal prices.
Growing aluminum prices have been providing support to domestic producers like Constellium. Although ceasefire efforts have eased immediate concerns over supply disruptions, uncertainty surrounding shipping through the Strait of Hormuz continues to weigh on global energy markets. The uncertainty has helped keep aluminum prices elevated, benefiting major industry participants such as Constellium.
The company generated adjusted EBITDA of $102 million in the first quarter, reflecting a 24% year-over-year increase, primarily driven by higher shipment volumes and favorable foreign exchange impacts. These gains were partially offset by an unfavorable price and product mix, along with higher operating costs stemming from increased business activity.
The A&T segment continues to benefit from robust aerospace demand, solid industrial and defense shipments, and supportive aluminum pricing trends, positioning Constellium for sustained growth in the quarters ahead.

Alcoa Corporation AA continues to benefit from strength in its Aluminum segment, driven by solid demand across packaging, electrical and transportation markets. Alcoa’s segment’s production capacity has increased following the restart of the San Ciprián smelter in Spain, Alumar in Brazil and Lista in Norway.
