Constellium Q1 2026 Earnings Snapshot

Net Margin Climbs to 3.2% on US$8.4b Sales

• On a trailing 12 month basis, Constellium earned net income of US$273 million on US$8.4b of revenue, which works out to a 3.2% net profit margin compared with 0.8% in the prior year period.
• Consensus narrative sees long term support from sustainability focused demand and recycling, and this higher 3.2% margin lines up with that view. However, the earlier trailing margin of 0.8% shows how thin profitability can be:
  • Supporters point to efficiency efforts like the Vision 25 program as a way to keep margins closer to the current 3.2% level even when costs are high.
  • Cautious investors may look at the gap between 3.2% and 0.8% and ask how stable that improvement really is if volumes or input costs move against the company.

Earnings Swing Versus 5 Year Decline

• Trailing 12 month earnings grew by a very large 387.5% compared with the prior year, while the longer term 5 year compound change in earnings is a 18.5% decline each year.
• Bulls argue that cost actions and demand for lightweight recyclable aluminum can keep earnings on a better path, yet the 5 year decline tempers that story:
  • The jump to trailing EPS of US$1.95 contrasts with earlier quarters such as Q4 2024, when basic EPS was a loss of US$0.33 on revenue of US$1.7b.
  • At the same time, the longer term 18.5% annual earnings decline shows that turning short term improvement into a steadier record is still an open task for the bullish case.

On a year like this, where earnings have moved from loss making periods to US$273 million of profit, it is worth seeing how bullish investors join the dots from these numbers to their longer term story for the business 🐂 Constellium Bull Case

Low P/E Versus Peers, High Debt Load

• Constellium trades on a 16.1x P/E, below the US Metals & Mining industry at 22.1x and a peer average of 48.4x, while also carrying high debt and showing trailing net profit margin of 3.2%.
• Bears focus on that high leverage and modest growth outlook, and the numbers give them some solid footing alongside the lower multiple:
  • The company is described as having a high level of debt, which matters when forecast earnings growth in the data is only around 3% per year and revenue growth is 0.5% per year.
  • Even with the current share price of US$32.23 sitting close to the DCF fair value of about US$32.94, bears can point to the combination of leverage and low expected growth as reasons the discount to industry P/E may persist.

For anyone weighing that lower 16.1x P/E against the debt and growth profile, it can help to read how cautious investors frame the downside risks around these same figures 🐻 Constellium Bear Case
