AI Analysis

AI-generated, general educational analysis — not personal investment advice.

I am looking at Constellium as a cyclical aluminum converter, not a wide-moat franchise. The business sells rolled and extruded aluminum into aerospace, packaging, automotive, transportation, and defense. Customer qualifications and scale give it some switching costs, but aluminum remains commodity-linked, and the computed Peter Lynch category is CYCLICAL — Aluminum: earnings follow the economic cycle. The filed numbers show a sharp rebound. In fiscal 2025, the year ended 2025-12-31, revenue was $8.4B, net income $273.0M, and diluted EPS $1.92. That compares with fiscal 2024 revenue of $7.3B, net income $56.0M, and diluted EPS $0.38. In fiscal Q1 2026, the quarter ended 2026-03-31, revenue was $2.5B, net income $199.0M, and diluted EPS $1.42, up from fiscal Q1 2025 revenue of $2.0B, net income $37.0M, and diluted EPS $0.26. Trailing free cash flow is $218.0M, a 6.2% FCF yield by FairStock's calculation. At the 2026-10-13 close of $25.77, FairStock calculates a P/E of 6.66, P/B of 2.80, EV/EBITDA of 4.41, and Graham Number of $28.29, leaving an 8.91% margin of safety. The Piotroski F-Score is 8/9, and FairStock's ROE is 53.09%, though ROCE is only 9.93%. Debt is high: D/E of 1.53 and Altman Z-Score of 1.39, which demands caution. The price looks inexpensive if earnings hold, but this is a cyclical, capital-intensive business. I would want to see consistent free cash flow and lower leverage before calling it a staple-like bargain.

In plain English: Constellium makes aluminum products for airplanes, cars, packaging, and industrial uses. Recent filed results show a large profit rebound, but the company carries a lot of debt and its earnings depend on the economic cycle. At the latest close, the shares look modestly inexpensive compared with the company's earnings and cash flow, though not a safe all-weather bargain.
