A Look At Constellium (CSTM) Valuation After New Airbus Supply Agreement

Airbus agreement puts fresh attention on Constellium stock

Constellium (CSTM) has drawn fresh investor attention after announcing a multi year agreement to supply Airbus with aluminum alloy extrusions and its Airware aluminum lithium solution for demanding aircraft structural applications.

See our latest analysis for Constellium.

The Airbus agreement comes as Constellium’s share price has climbed to US$30.28, supported by a 35.30% 1 month share price return and a very large 1 year total shareholder return. Together, these figures point to strong recent momentum rather than fading interest.

Most Popular Narrative: 10.9% Undervalued

Constellium’s most followed narrative pegs fair value at $34.00 per share, which sits above the latest $30.28 close and frames the recent Airbus news against a wider aluminum story.

Constellium looks like one of the more compelling value-oriented names in the materials space. The company is not a pure commodity aluminum bet. It is a producer of high-value-added rolled and extruded aluminum products serving aerospace, packaging, automotive, and industrial markets, with a growing competitive edge in recycling and closed-loop aluminum systems. In 2025, it delivered $8.4 billion of revenue, $846 million of adjusted EBITDA, $275 million of net income, and $178 million of free cash flow, while guiding to $780 to $820 million of adjusted EBITDA and more than $200 million of free cash flow in 2026.

Read the complete narrative.

This narrative leans heavily on earnings quality, recycling economics, and the mix of aerospace, packaging, and automotive volumes. To see which revenue, margin, and cash flow assumptions sit behind that $34.00 fair value and 10.9% discount to price, the full story sets out the financial blueprint in detail.

Result: Fair Value of $34.00 (UNDERVALUED)
