Constellium NV (NYSE: CSTM) saw its stock price surge 5.74% in pre-market trading on Wednesday, following the release of its first quarter 2025 financial results. The aluminum products manufacturer reported solid earnings and maintained its full-year guidance, boosting investor confidence.

The company reported earnings per share (EPS) of $0.26 for Q1 2025, meeting analyst expectations and marking a significant 85.71% increase from $0.14 per share in the same period last year. While quarterly revenue of $1.98 billion slightly missed the analyst consensus estimate of $2.01 billion, it still represented a 5.27% year-over-year increase.

A key highlight of the report was Constellium's Adjusted EBITDA, which rose to $186 million from $146 million in Q1 2024. This substantial improvement in profitability likely contributed to the positive market reaction. Additionally, the company maintained its full-year 2025 guidance, projecting Adjusted EBITDA in the range of $600 million to $630 million and Free Cash Flow in excess of $120 million. This outlook suggests management's confidence in the company's performance for the remainder of the year.

Jean-Marc Germain, Constellium's Chief Executive Officer, commented on the results, stating, "Constellium delivered solid results in the first quarter despite continued demand weakness across most of our end markets outside of packaging and some lingering impacts from the flood last year at our Valais operations." The company's ability to deliver strong results in challenging conditions appears to have resonated well with investors, contributing to the pre-market stock price increase.
