Welcome to our dedicated page for Constellium Se SEC filings (Ticker: CSTM), a comprehensive resource for investors and traders seeking official regulatory documents including 10-K annual reports, 10-Q quarterly earnings, 8-K material events, and insider trading forms.
The Constellium SE (NYSE: CSTM) SEC filings page on Stock Titan provides access to the company’s regulatory disclosures filed with the U.S. Securities and Exchange Commission. As an NYSE‑listed issuer of ordinary shares, Constellium submits periodic and current reports that describe its financial condition, segment performance, governance changes and other material events.
Among the most relevant documents for investors are current reports on Form 8‑K. Constellium uses Form 8‑K to announce results of operations and financial condition under Item 2.02, typically in connection with quarterly earnings releases and investor presentations. These filings reference detailed press releases and slide decks that include shipments, revenue, net income, Adjusted EBITDA, Segment Adjusted EBITDA for the Aerospace & Transportation (A&T), Packaging & Automotive Rolled Products (P&ARP) and Automotive Structures & Industry (AS&I) segments, as well as the impact of metal price lag.
Constellium also files 8‑Ks under Item 5.02 to disclose departures and appointments of directors and certain officers and related compensatory arrangements. For example, the company has reported the Board’s decision to appoint Ingrid Joerg as Chief Executive Officer and director, effective January 1, 2026, and has outlined the key terms of her employment agreement. The same filing describes the planned transition of Jean‑Marc Germain to a Special Advisor role and summarizes his transition agreement.
Over time, investors can also review annual reports on Form 10‑K and quarterly reports on Form 10‑Q (when available) to analyze Constellium’s consolidated financial statements, risk factors, segment information, discussion of metal price lag and explanations of trends in its aerospace, packaging, automotive and industrial businesses. Forms 3, 4 and 5, when filed, provide data on insider holdings and changes in ownership by directors and officers.
Stock Titan enhances these filings with AI-powered summaries that explain key points in plain language, highlight important changes from prior periods and draw attention to items such as segment performance, leverage metrics, share repurchases, leadership changes and compensation arrangements. Real-time updates from EDGAR help ensure that new CSTM filings, including 10‑K, 10‑Q, 8‑K and insider transaction reports, appear promptly so users can review the underlying documents and AI insights in one place.

The amendment shows a total interest in 20,734 ordinary-share-linked units, consisting of 1,500 ordinary shares held directly as of January 1, 2026 and 19,234 restricted stock units that remain subject to vesting restrictions and were previously omitted from his original Form 3 and one Form 4. This update does not reflect any new share purchases or sales, but rather a clarification of prior disclosures.

As of January 1, 2026, he reports beneficial ownership of 30,242 ordinary shares, consisting of 18,115 ordinary shares held outright and 12,127 restricted stock units that remain subject to vesting and were inadvertently omitted from his original Form 3.

CONSTELLIUM SE filed an amended Form 3 for executive Matthew B. Perkins, President, P&ARP. The amendment clarifies that he beneficially owns an aggregate of 23,002 restricted stock units, which remain subject to vesting restrictions and were inadvertently omitted from his original Form 3 filing. This is a holdings correction, not a new share purchase or sale.
CONSTELLIUM SE executive Philip Ryan Jurkovic filed an amended Form 3 to correct his reported equity holdings. The filing shows he holds 181,347 ordinary shares in total, including 130,739 ordinary shares held as of January 1, 2026 and 50,608 restricted stock units that remain subject to vesting and were inadvertently omitted from his original Form 3. This amendment is an administrative update to accurately reflect his ownership position rather than a new share purchase or sale.
CONSTELLIUM SE CEO Ingrid Joerg has amended her initial insider holdings report. The amended Form 3 shows she holds 311,572 ordinary shares as of January 1, 2026. This total consists of 186,691 ordinary shares and 124,881 restricted stock units that remain subject to vesting and were inadvertently omitted from the original Form 3 filing.
CONSTELLIUM SE executive Philippe Hoffmann, President of A&T, reports beneficial ownership of 195,716 ordinary shares as of January 1, 2026. This amount consists of 135,425 ordinary shares held directly and 60,291 restricted stock units that remain subject to vesting. The amendment corrects Hoffmann’s original Form 3 and one prior Form 4, where these restricted stock units were inadvertently omitted, so it updates the disclosed size of his equity stake without reporting a new transaction.
CONSTELLIUM SE executive vice president and CFO Jack Q. Guo amended his insider holdings disclosure. The Form 3/A reports beneficial ownership of 156,722 ordinary shares, consisting of 73,792 ordinary shares held as of January 1, 2026 and 82,930 restricted stock units that remain subject to vesting and were previously omitted.
CONSTELLIUM SE senior vice president and chief procurement officer Marcus Becker filed an amended Form 3 to update his reported holdings.

CONSTELLIUM SE filed an amended Form 3 for President, AS&I Stephane Corre to update his reported holdings. As of January 1, 2026, he beneficially owns 64,694 ordinary shares in total.
This amount consists of 50,644 ordinary shares held directly and 14,050 restricted stock units that remain subject to vesting restrictions. The amendment explains these RSUs were inadvertently omitted from Corre’s original Form 3 and from two Form 4 filings submitted before this amendment, so the change reflects a correction to previously reported ownership rather than a new transaction.
