The company's recent history underscores its resilience. In 2024, Constellium faced significant headwinds, including operational disruptions at its Muscle Shoals plant due to extreme weather and severe flooding at its Valais facilities in Switzerland. These events, coupled with widespread demand weakness and tightening scrap spreads in North America, materially impacted financial performance. In response, Constellium accelerated its Vision 25 cost reduction program and implemented aggressive working capital reductions. The Valais operations, which were severely impacted, resumed normal operations by Q1 2025 and are expected to emerge with a lower overall cost structure. Similarly, the Muscle Shoals plant has shown consistent operational improvement, stabilizing its performance. These internal initiatives, alongside successful refinancing of senior notes and extension of its ABL facility in 2024, have enhanced the company's financial flexibility. ## Financial Performance and Outlook Constellium delivered a solid financial performance in the second quarter of 2025, despite continued demand weakness across most end markets outside of packaging. Revenue for the three months ended June 30, 2025, increased 9% year-over-year to $2,103 million, driven by higher shipments and improved revenue per ton. For the first half of 2025, revenue grew 7% to $4,082 million. Net income for Q2 2025 was $36 million, contributing to a first-half net income of $74 million. Adjusted EBITDA, excluding the non-cash impact of metal price lag, stood at $159 million for Q2 2025, bringing the first-half total to $299 million. This compares to $180 million in Q2 2024 and $340 million in H1 2024, reflecting the challenging market environment.

Segment-wise, the Packaging Automotive Rolled Products (PARP) segment was a standout performer, with Adjusted EBITDA increasing 12% to $74 million in Q2 2025. This was fueled by a 5% increase in shipments, primarily from healthy packaging demand and improved operational performance at Muscle Shoals. In contrast, the Aerospace Transportation (AT) segment saw its Adjusted EBITDA decline 13% to $78 million, largely due to an 11% drop in shipments as commercial OEMs worked through excess inventory. The Automotive Structures Industry (ASI) segment experienced a significant 40% decrease in Adjusted EBITDA to $18 million, impacted by weaker pricing, unfavorable mix, and the net effect of tariffs. The company's cost of sales increased due to higher metal prices, while selling and administrative expenses rose due to labor costs and corporate transformation projects. Research and development expenses, however, decreased, reflecting a focus on non-labor cost efficiencies. Constellium's liquidity remains robust, with $841 million in total liquidity as of June 30, 2025, comprising $133 million in cash and equivalents, and substantial availability under its credit facilities. The company generated $41 million in free cash flow in Q2 2025, bringing the year-to-date total to $38 million. This cash generation, despite working capital usage for Valais inventory rebuilding, underscores the company's financial discipline. Net debt stood at $1.9 billion, resulting in a leverage ratio of 3.6x. Management views this as a peak, projecting leverage to trend down to or below 3x by year-end and within their long-term target range of 1.5x-2.5x. The company continues its share repurchase program, buying back 3.4 million shares for $35 million in Q2 2025, with $171 million remaining under the current authorization.

Looking ahead, Constellium has raised its full-year 2025 Adjusted EBITDA guidance (excluding metal price lag) to a range of $620 million to $650 million, and expects Free Cash Flow in excess of $120 million. This revised outlook anticipates a modest improvement in the second half of 2025, driven by the timing of tariff mitigations, customer compensations, more favorable scrap purchasing dynamics (expected to benefit from Q3 onwards), the full ramp-up of Valais operations, and favorable foreign exchange translation. Capital expenditures are projected at around $325 million for the full year. For 2028, Constellium has set ambitious long-term targets of $900 million in Adjusted EBITDA and $300 million in Free Cash Flow. This growth is expected to be fueled by the full recovery and optimized cost structure of Valais, continued operational improvements at Muscle Shoals, and contributions from strategic investments. These investments include the new recycling and casting center in Neuf-Brisach, cast house investments in Versailles and Ravenswood, and battery foil initiatives. The company's projections for market growth are prudently set below current industry estimates, emphasizing disciplined pricing and strict cost control as key drivers. ## Risks and Strategic Responses The investment thesis is not without its challenges. The tariff and international trade situation remains highly unpredictable, creating uncertainty, particularly in the automotive market. While Constellium's U.S. automotive structures business faces increased costs from Section 232 tariffs on Canadian extrusions (estimated at $20 million for the rest of 2025 before mitigation), the company is actively pursuing pass-throughs with customers and exploring alternative sourcing. Management views the overall tariff situation as a net positive, as it makes domestically produced flat-rolled aluminum more competitive, leading to price increases for its U.S. products. Continued supply chain challenges in the aerospace sector are causing a "shift in demand to the right" for some products, impacting near-term volumes despite robust backlogs. The automotive market, especially in Europe, remains weak, with production levels still below pre-COVID figures and further softening in North America due to tariff impacts. Constellium is proactively managing these demand weaknesses by accelerating its Vision 25 cost improvement program and optimizing capacity, including shifting production from automotive to packaging where feasible. The tightening of scrap spreads in North America also presents a headwind for metal costs, particularly for the PARP segment, though management expects some benefit from widening spreads starting in Q3 2025. Despite these challenges, Constellium's diversified portfolio and flexible business model are critical assets, allowing it to adapt to varying market conditions and mitigate risks. ## Conclusion Constellium SE is a compelling investment proposition, rooted in its specialized aluminum product portfolio, technological leadership, and demonstrated operational resilience. The company's ability to innovate with advanced alloys and recycling processes, coupled with its strategic focus on high-growth and sustainable end-markets, provides a durable competitive advantage. While the macroeconomic environment, particularly in automotive and aerospace supply chains, presents near-term headwinds, Constellium's proactive cost control through its Vision 25 program, successful operational turnarounds at Muscle Shoals and Valais, and strategic capital investments position it for robust future growth. The raised 2025 guidance and ambitious 2028 targets underscore management's confidence in their ability to drive profitability and free cash flow, even as they navigate a complex global landscape. The commitment to deleveraging and consistent shareholder returns through buybacks further enhances the investment appeal. Constellium's strategic positioning, underpinned by its technological prowess and disciplined execution, suggests a clear path to unlocking significant shareholder value as global demand for lightweight, sustainable aluminum solutions continues to expand.
