Key Growth Drivers for Constellium

The Packaging & Automotive Rolled Products segment is currently fueling Constellium’s growth. In 2025, shipments in this segment climbed 6% year-over-year to 1,086,000 metric tons, supported by robust demand. Segment revenue jumped 21% to $5.1 billion, thanks to higher metal prices. Increased orders for packaging rolled products in North America and Europe, as well as automotive rolled products in North America, are propelling performance.

Additionally, the Aerospace & Transportation segment is contributing positively. Shipments reached 207,000 metric tons in 2025, and revenue rose 8% to nearly $2 billion, driven by strong demand and favorable metal prices. Orders for transportation, industrial, and defense rolled products remain healthy.

The Automotive Structures & Industry segment is also seeing gains, with shipments totaling 202,000 metric tons and revenue up 10% to about $1.6 billion. Overall, Constellium’s total revenue for the year surged 15% to $8.5 billion compared to the previous year, supported by segment strength and rising metal prices.

Constellium is expected to benefit from elevated aluminum prices, which have been impacted by disruptions in the Strait of Hormuz due to the Israel-Iran conflict, affecting regional supply and boosting global prices.

The company continues to prioritize shareholder returns, generating $178 million in free cash flow in 2025 and repurchasing approximately $115 million in shares. The board recently approved a new buyback program to acquire up to $300 million in shares, effective from May 21, 2026, through December 31, 2028. Cost management remains a focus, with leverage reduced to 2.5x by year-end 2025.
