Letter from the Chairman and CEO of Constellium

Dear Constellium Shareholders:

On behalf of Constellium SE, we are pleased to invite you to review our 2025 Proxy Statement. This document outlines key matters to be presented at our upcoming Annual General Meeting on May 15, 2025, at 5:00 pm CET (11:00 am EDT), and we encourage your participation and engagement as valued shareholders in our company.

As we decided to voluntarily file our SEC reports on U.S. domestic issuer forms in 2025, including our Annual Report for the fiscal year 2024 (Form 10-K) earlier this year, we also elected to voluntarily file this Proxy Statement with the SEC on a U.S. domestic issuer form (utilizing Form 8-K) for our upcoming Annual General Meeting. We believe that this new format, which includes additional information on governance and executive compensation, will provide useful insights to our shareholders.

In this Proxy Statement, you will find important details regarding the items to be voted on, including the election of directors. We believe these proposals align with our mission to drive sustainable profitability and uphold the highest standards of corporate responsibility.

Constellium is deeply committed to sound corporate governance and executive compensation policies and practices to ensure we operate responsibly, efficiently, and in the best interests of shareholders. The diversity of experience, background and skills present in the boardroom allows for active Board oversight of the opportunities and issues ahead of Constellium as we make progress on our strategic roadmap. Our Board strikes the right balance between fresh perspectives and established experience, as we regularly add new directors to the Board. This year, we are pleased to submit to vote the nomination of Mr. Bradley L. Soultz to our Board. As the current CEO of WillScot and a former executive at Novelis, he brings an impressive combination of skills, experience, and deep industry knowledge with his background in aluminum fabrication that will serve our shareholders, Constellium and our Board well.

Looking at our recent performance, 2024 was a challenging year for us on many fronts. The year began with the extreme cold weather and snow impacting operations at Muscle Shoals in January and we experienced severe flooding at our facilities in the Valais region in Switzerland during the summer. In addition, we faced market-driven headwinds starting mid last-year and which became more pronounced in the second half, including demand weakness across most of our end markets and significant tightening of scrap spreads in North America. Despite all of these challenges in the near-term, we have demonstrated that we have the right strategy, the right teams, and the right products in the right markets, and that we know how to overcome crises. Our business model is flexible and resilient; our diversified portfolio allows us to always have options in very different market conditions; we have built the balance sheet we need to both weather crises and seize opportunities; and our high-value, recyclable and sustainable products respond to the growing needs of our customers. As such, back in February this year we provided financial guidance for 2025 and established new long-term financial targets for 2028. At Constellium, we remain committed to delivering long-term value to our shareholders through innovation, operational excellence, and a focus on commercial and capital discipline. We believe we are well-positioned for long-term success and remain focused on executing our strategy and shareholder value creation.

To wrap up, thank you for your continued trust and investment in Constellium. Your vote is critical in shaping the future of Constellium, and we encourage you to participate in this process. Whether you choose to vote online, by mail, or in person at the Annual General Meeting, your voice matters. We look forward to your engagement and a productive discussion at the upcoming meeting.


Sincerely,

/s/ Jean-Christophe Deslarzes			/s/ Jean-Marc Germain

EXPLANATORY NOTE

Constellium SE (“Constellium SE” or the “ Company”), a company organized under the laws of France, qualifies as a foreign private issuer, as determined by Rule 3b-4 under the Securities Exchange Act of 1934 (the “Exchange Act”) and is exempt from the proxy solicitation rules under Section 14 of the Exchange Act (including the requirement to furnish a Proxy Statement in accordance with Schedule 14A thereof) and Regulation FD. However, beginning in 2025, Constellium SE has decided to voluntarily file its quarterly and annual reports with the U.S. Securities and Exchange Commission (the “SEC”) on U.S. domestic company forms. Constellium US Holdings I, LLC which is a subsidiary of Constellium SE also maintains the following IRS Identification Number: 27-4126819.

Following its decision to voluntarily file reports on U.S. domestic company forms, starting with its annual report on Form 10-K (the “Annual Report”) for the fiscal year 2024 filed earlier this year, the Company has also elected to voluntarily publish a proxy statement for its annual general meeting to be held in 2025 (“Annual General Meeting” or the “Shareholders Meeting”) in a format intended to substantially comply with the requirements of Schedule 14A of the Exchange Act. Therefore, our fiscal year 2024 disclosures with respect to the notice of and solicitation of votes for our Annual General Meeting are now in a different format than previous years.

Shareholders this year are receiving this Notice of 2025 Annual General Meeting and the proxy statement (the “Proxy Statement”) and the Annual Report.

These risks and uncertainties include, but are not limited to: market competition; economic downturn or industry specific conditions including the impacts of tax and tariff programs, inflation, foreign currency exchange, and industry consolidation; disruption to business operations; natural disasters including severe flooding and other weather-related events; the conflict between Russia and Ukraine and other geopolitical tensions; the inability to meet customer demand and quality requirements; the loss of key customers, suppliers or other business relationships; supply disruptions; excessive inflation; the capacity and effectiveness of our hedging policy activities; the loss of key employees; levels of indebtedness which could limit our operating flexibility and opportunities; and other risk factors set forth under the heading “Risk Factors” in our Annual Report on Form 10-K, and as described from time to time in subsequent reports filed with the U.S. Securities and Exchange Commission. The occurrence of the events described, and the achievement of the expected results depend on many events, some or all of which are not predictable or within our control.

TABLE OF CONTENTS

What is an “abstention” and how would it affect voting?

An “abstention” occurs when a shareholder votes with instructions to abstain from voting regarding a particular resolution or, unless otherwise instructed in the proxy card without making a selection with respect to a particular matter.

An abstention will be counted toward the presence of a quorum. Because an abstention from voting is not voted affirmatively or negatively, it will have no effect on the approval of any of the resolutions.

What are the quorum requirements for the resolutions?

Each shareholder as of the French Record Date is entitled to one vote per ordinary share. The quorum necessary for the Ordinary Resolutions (resolutions 1 to 11) is 1/5 of the voting shares. The quorum necessary for the Extraordinary Resolutions (resolutions 12 to 22) is 1/4 of the voting shares. Abstentions are treated as ordinary shares that are present for purposes of determining the presence of a quorum. If a quorum is not present, the meeting will be adjourned.

What are the voting requirements for the resolutions?

The affirmative vote of a majority of the total number of votes cast is required for the Ordinary Resolutions (resolutions 1 to 11). For approval of the Extraordinary Resolutions (resolutions 12 to 21), the affirmative vote of two-thirds of the total number of votes cast is required. Abstentions will not count as votes cast on any of the resolutions presented at the Annual General Meeting.

What is a “broker non-vote”?

A broker non-vote occurs when a broker, bank or other nominee votes on behalf of a beneficial owner for the Annual General Meeting but abstains from voting on a particular resolution because such broker, bank or other nominee does not have discretionary voting power with respect to that resolution and has not received voting instructions from the beneficial owner. If you own ordinary shares in “street name” through a broker, bank or other nominee and you do not direct your broker how to vote your shares on the proposals, the broker will have to give an abstention instruction, and your shares will not be counted as votes cast on any proposal on which the broker does not have discretionary authority to vote.

Who can I contact if I have questions about voting my ordinary shares or attending the Annual General Meeting?

If you have any questions about voting your ordinary shares or attending the Annual General Meeting, please contact the Company Investor Relations department by email at investor-relations@constellium.com.

TABLE OF CONTENTS

Board Leadership and Corporate Governance Framework

We currently have a single-tier Board of Directors consisting of one executive director (the CEO) and ten non-executive directors, two of which are employee directors. We also have one new director nominee.

The Board of Directors supervises the management of the executive officers, sets the guidelines for the Company's activities, oversees and approves the Company’s strategy and oversees its implementation. Subject to the powers expressly reserved by law to the shareholders' meetings and within the limit of the corporate purpose, the Board of Directors considers any issue relevant to the Company's business and operations and through its deliberations settles the matters of concern to it, taking into consideration the social and environmental impact of the company's activities. The Board of Directors also exercises certain special powers conferred on it by law.

Each director has a duty towards the Company to properly perform his/her duties. Furthermore, each director has a duty to act in the corporate interest of the Company. The corporate interest extends to the interests of all corporate stakeholders, such as shareholders, creditors, employees, customers and suppliers.

Board Charter

The Board Charter describes the purpose and responsibilities of the Board of Directors. The Board of Directors determines the guideline for the Company's activities and oversees their implementation in accordance with the corporate interest of the Company taking into consideration the social and environmental impact of its activity. The Board Charter is issued pursuant to article 13.4 of the Articles of Association and complement the applicable rules of French law and of the New York Stock Exchange (the “NYSE”). The Board, amongst other duties, has responsibility and approval authority over strategic investment projects and transactions, oversees corporate governance, appoints executive corporate officers, such as the Chief Executive Officer (“CEO”), and if any, deputy CEOs (and sets their remuneration and benefits), and may replace directors if determined appropriate by the Board in case of vacancy (subject to a subsequent shareholder approval). The Board of Directors can convene shareholders’ meetings, approve annual financial statements, and ensure the preparation of annual reporting filings. Under the Board Charter, directors shall attend all meetings of the Board and of the Committees of which they are a member, and to the extent deemed necessary, the shareholders’ meetings. Two of our directors attended the Company's annual shareholder meeting in 2024. The Board of Directors held nine meetings in 2024. None of the directors fell below 75% attendance at either Board meetings or Committee meetings of which they were a member.

Role of the Board in Risk Oversight

Our Board of Directors is primarily responsible for the oversight of our risk management activities and has delegated to the Audit Committee the responsibility to assist our Board of Directors in this task. The Audit Committee also monitors our financial reporting process and internal control systems. The Audit Committee reviews and discusses with management, and, as appropriate, the Company's auditors, the Company's guidelines and policies with respect to risk assessment and risk management, including the Company's financial and other significant risk exposures, and the steps taken by management to monitor and control those exposures. For a description of the principal duties and responsibilities of the audit committee, see “– Board Committees – Audit Committee” below.

TABLE OF CONTENTS

While our Board of Directors oversees our risk management, our management is responsible for day-to-day risk management processes. Our Board of Directors expects our management to consider risk and risk management in each business decision, to proactively develop and monitor risk management strategies and processes for day-to-day activities and to effectively implement risk management strategies adopted by the Board of Directors. We believe this division of responsibilities is the most effective approach for addressing the risks we face.

Director Independence

Under French law, there are no director independence requirements for French companies not listed on an EU-regulated market, so we defer to the NYSE requirements. As a foreign private issuer under the NYSE rules, we are not required to have independent directors on our Board of Directors, except with respect to our Audit Committee which is required to consist of independent directors. Under the Company's Board Charter, no director can be considered independent unless the Board of Directors affirmatively determines that such director has no material relationship with the Company, either directly or as a partner, shareholder or officer of an organization that has a relationship with the Company. On an annual basis, the Board of Directors reviews each director and their independence. Under the Board Charter, the Board of Director's determination of independence includes consideration of the following:

(a)	the director is, or has been within the last three years, an employee of the Company, or an immediate family member is, or has been within the last three years, an executive officer, of the Company;

(b)

the director has received, or has an immediate family member who has received, during any twelve-month period within the last three years, more than $120,000 in direct compensation from the Company, other than director and committee fees and pension or other forms of deferred compensation for prior service (provided such compensation is not contingent in any way on continued service);

(c)

(A) the director is a current partner or employee of a firm that is the Company's internal or external auditor; (B) the director has an immediate family member who is a current partner of such a firm; (C) the director has an immediate family member who is a current employee of such a firm and personally works on the Company's audit; or (D) the director or an immediate family member was within the last three years a partner or employee of such a firm and personally worked on the Company's audit within that time;

(d)	the director or an immediate family member is, or has been within the last three years, employed as an executive officer of another company where any of the Company's present executive officers at the same time serves or served on that company's compensation committee; and;

(e)

the director is a current employee, or an immediate family member is a current executive officer, of a company that has made payments to, or received payments from, the listed company for property or services in an amount which, in any of the last three fiscal years, exceeds the greater of $1 million, or 2% of such other company's consolidated gross revenues.

Our Board of Directors has determined that, under current NYSE listing standards regarding independence and under its Board Charter, as of December 31, 2024, Messrs. Brandjes, Deslarzes, Ormerod, Puig, and Blot and Mmes. Boccon-Gibod, Brooks and Walker are deemed independent directors. Under NYSE standards and the Board Charter, Mr. Germain is not deemed independent as he serves as the CEO of the Company, and Mr. Verdier and Ms. Weiler are not deemed independent as they are employees of the Company.

Balance of Board Representation and Employee Directors

According to Article L. 225-17 of the French Commercial Code, the appointment of members of a board of directors must seek to achieve a balanced representation of men and women. As of December 31, 2024, our Board of Directors is comprised of eleven members, four of whom are women.

Also, under French law, if the number of permanent employees of a company exceeds 1,000 (including its direct and indirect French subsidiaries) or 5,000 (including its direct and indirect subsidiaries worldwide) for two consecutive fiscal years, an amendment of the articles of association may be required for the board of directors to include at least two directors representing the employees (in companies having more than eight directors) or at least one director representing the employees (in companies having no more than eight directors). Following the amendment, --of our

TABLE OF CONTENTS

Articles of Association --which was approved at the Company's Annual General Meeting held on May 11, 2021 to allow for such appointment, two employees of the Company’s subsidiaries, Mr. Verdier and Ms. Weiler, were appointed to our Board of Directors by, respectively, the French Group Works Council and the European Works Council.

Board Committees

Under French law, the Board of Directors may appoint from its members one or more special committees, for which the Board sets the composition and powers, and which carry out their activity under the Board's responsibility. Each committee reports on its activities at the meetings of the Board of Directors. Our Board of Directors currently has four committees: the Audit Committee, the Human Resources Committee, the Nominating and Governance Committee and the Safety and Sustainability Committee. The charters of each of the Company's Board committees can be accessed on our website at http://www.constellium.com/investors/governance. Under French law, committees of the Board of Directors make recommendations to the Board of Directors and the Board of Directors has the authority to approve such recommendations.

Audit Committee

As of December 31, 2024, our Audit Committee consisted of three directors, each of whom is independent under the NYSE requirements: Lori Walker (Chair), Isabelle Boccon-Gibod, and John Ormerod. Our Board has determined that each of Ms. Walker and Mr. Ormerod is an “audit committee financial expert” as defined by the SEC and also meets the additional criteria for independence of audit committee members set forth in Rule 10A-3(b)(1) under the Exchange Act. The Audit Committee held eight meetings in 2024, with 100% director attendance at all Audit Committee meetings.

The duties and responsibilities of our Audit Committee are set forth in the Audit Committee Charter. Certain principal duties of the Audit Committee are to oversee and monitor the following:

•	our financial reporting process and internal control system;

•	the integrity of our consolidated financial statements, and disclosure matters;

•	the independence, qualifications and performance of our independent auditors;

•	the performance of our internal audit function;

•	financial and other significant risk exposure; and

•	our compliance with legal, ethical and regulatory matters.

Human Resources Committee

As of December 31, 2024, our Human Resources Committee consisted of three directors: Martha Brooks (Chair), Jean-Christophe Deslarzes, and Jean-Philippe Puig. The Human Resources Committee held four meetings in 2024, with 100% director attendance at all the Human Resources Committee meetings.

The duties and responsibilities of our Human Resources Committee are set forth in the Human Resources Committee Charter. Certain principal duties of the Human Resources Committee are to oversee and monitor the following:

•	to review and make recommendations to the Board with respect to our compensation philosophy, policies and structure and with respect to our annual incentive compensation and equity-based compensation plans;

•	to review the compensation of, and reimbursement policies for, members of the Board;

•	to review and approve the corporate goals, performance and compensation structure of our Chief Executive Officer;

•	to review and approve the compensation structure for all employees who report directly to our Chief Executive Officer;

•	to oversee our critical strategic or major human capital issues, including amongst other items, inclusion, employment engagement surveys and talent development programs; and

•	to oversee the selection of officers and management succession planning.

TABLE OF CONTENTS

Nominating and Governance Committee

As of December 31, 2024, our Nominating and Governance Committee consisted of five directors: John Ormerod (Chair), Isabelle Boccon-Gibod, Michiel Brandjes, Jean-Christophe Deslarzes and Lori Walker. The Nominating and Governance Committee held six meetings in 2024, with 100% director attendance at all the Nominating and Governance Committee meetings.

The duties and responsibilities of the Nominating and Governance Committee are set forth in the Nominating and Governance Committee Charter. Certain principal duties of the Nominating and Governance Committee are to oversee and monitor the following:

•	to establish criteria for Board and committee membership and recommend to our Board proposed nominees for election to the Board and for membership on committees of our Board;

•	to conduct succession planning for the Chair of the Board, and for the Chief Executive Officer;

•	to make recommendations to our Board regarding Board governance matters and practices;

•	to oversee the annual self-assessment of the Board and its committees; and

•	to review Board corporate governance matters, including conflicts of interest, related party matters and director independence.

Safety and Sustainability Committee

As of December 31, 2024, our Safety and Sustainability Committee consisted of four directors: Michiel Brandjes (Chair), Emmanuel Blot, Martha Brooks and Jean-Philippe Puig. The Safety and Sustainability Committee held four meetings in 2024, with 100% director attendance at all the Safety and Sustainability Committee meetings.

The duties and responsibilities of the Safety and Sustainability Committee are set forth in the Safety and Sustainability Committee Charter. Certain principal duties of the Safety and Sustainability Committee are to oversee and monitor the following:

•	to review periodically the Company's policies, practices and programs with respect to the overall management of safety and sustainability matters, including climate change and environmental matters;

•	to oversee the implementation and effectiveness of the Company's employee safety risk-management procedures, policies, practices, programs and initiatives;

•	to review the Company's record of compliance with laws, regulations and Company policies relating to safety and sustainability matters; and

•	to work with and advise the other Board committees in areas that come within the mandate of such committees and that also are part of the Company's sustainability initiatives.

Shareholder Proposals for the Appointment of Directors

Our Nominating and Governance Committee will consider candidates for director appointments as proposed by the shareholder(s). Under French law, one or several shareholders holding a percentage of the share capital defined by French law are permitted to submit proposals of resolutions for inclusion in the agenda of the shareholders’ meeting, including proposals for the appointment of a director. For details, see the section headed “Procedures for Shareholder Proposals for the Annual General Meeting”. The Nominating and Governance Committee will evaluate such proposals in accordance with its charter, the Board Charter, our Articles of Association, the relevant French law rules, and the Company’s own criteria for determining the suitability of a candidate for the Board of Directors. The Nominating and Governance Committee will then make a recommendation to the Board of Directors regarding how the Board of Directors should recommend to the shareholders to vote on the shareholder proposal.

Worldwide Code of Employee and Business Conduct

We have adopted a Code of Conduct that applies to all our employees, officers and directors, including our Chief Executive Officer, Chief Financial Officer and principal accounting officers. Our Code of Conduct addresses, among other things, competition and fair dealing, conflicts of interest, financial integrity, government relations, confidentiality and corporate opportunity requirements and the process for reporting violations of our Code of Conduct, employee misconduct, conflicts of interest or other violations. Our Code of Conduct is intended to meet the definition of “code of ethics” under Item 406 of Regulation S-K under the Exchange Act (“Regulation S-K”).

TABLE OF CONTENTS

A copy of our Code of Conduct is available on our website at www.constellium.com. Any amendments to the Code of Conduct, or any waivers of its requirements, will be disclosed on our website.

Policy for Reporting Wrongdoings (Whistleblower Policy)

The Company has adopted a Policy for Reporting Wrongdoings to address the Company’s commitment to ethical behavior by fostering an environment where employees as well as internal and external stakeholders are encouraged to raise concerns, report wrongdoing or suspected wrongdoing, and to ensure that employees are protected against retaliation.

The Policy for Reporting Wrongdoings establishes the process and describes the different channels for reporting and how those concerns will be investigated. The Company has established a compliance committee to oversee the policy and to ensure that appropriate actions are taken for each investigation and to report activity to the Audit Committee who has oversight over such matters. To facilitate this reporting, we have established internal reporting channels, an external hotline in all the countries and languages where we operate, and an ombudsman. The policy further establishes safeguards to protect the reporter.

Insider Trading Policy

We have an Insider Trading Policy that applies to all employees, officers, and directors, as well as their affiliates (including spouses, partners, children, other relatives, and certain entities which are affiliated with such individuals). The Insider Trading Policy prohibits Company personnel and affiliates who possess inside information from: executing, effecting, or attempting to execute or effect a transaction in Company securities or related derivative instruments; recommending or inducing a third party to execute or effect a transaction in Company securities or related derivative instruments; disclosing inside information about the Company; and executing or effecting a transaction in Company securities or related derivative instruments that gives or is likely to give false or misleading signals or information, seeks to secure a price at an artificial level, or uses deception or contrivance. The Insider Trading Policy also prohibits Company personnel who have access to the Company's quarterly earnings information from trading in Company securities or related derivative instruments prior to public release of earnings information.

RESOLUTION / PROPOSAL 10

Appointment of PricewaterhouseCoopers Audit as a Statutory Auditor in charge of certifying the consolidated sustainability information

Following transposition into the French Commercial Code of the provisions of Directive (EU) 2022/2464 of the European Parliament and of the Council of December 14, 2022 amending Regulation (EU) No 537/2014 and Directives 2004/109/EC, 2006/43/EC and 2013/34/EU as regards corporate sustainability reporting (the “CSRD”), the Shareholders' Meeting is invited to appoint an auditor in charge of certification of the consolidated sustainability information that the Company is required to publish, for the first time, in 2026 for the fiscal year 2025.

Upon recommendation of the Audit Committee followed by the Board of Directors, it is proposed to the Shareholders' Meeting to appoint, for the purposes of certification of the consolidated sustainability information, one of the Statutory Auditors, PricewaterhouseCoopers Audit, for a term of three fiscal years, i.e. until the end of the shareholders' meeting convened to approve the financial statements for the fiscal year ending December 2027.

At the time this report was about to be finalized, we were informed that the European Commission had published an “Omnibus” package of proposals destined to simplify European regulations on sustainability reporting, sustainability due diligence and green taxonomy. We do not know if and to which extent these proposals will be adopted by the European and French authorities. Should they be adopted, and depending on the format of adoption, the Company's sustainability reporting obligations resulting from the CSRD could be deferred, modified or eliminated.

Notwithstanding this evolving context, the Board of Directors recommends voting for this proposed resolution for the Company to be able to comply with its current legal obligations.

OVERVIEW - RESOLUTIONS / PROPOSALS 11 to 13

By submitting to the Shareholders' Meeting proposals 11 to 13, the Board of Directors is seeking the annual renewal of the authorizations required for the purposes of the share repurchase program announced by the Company on February 21, 2024 and any other share repurchase program that may be authorized by the Board of Directors from time to time in the future.

The Company is asking for the shareholders' authorization in proposal 11 to be able to repurchase its shares under the conditions set forth in article L. 225-209-2 of the French Commercial Code, it being understood that the Company can also repurchase its shares in accordance with article L. 225-208 of the French Commercial Code without the need for the shareholders' authorization.

The authorizations in proposals 12 and 13 would allow the Company to cancel the shares that it has repurchased.

RESOLUTION / PROPOSAL 11

Authorization to be given to the Board of Directors for the repurchase by the Company of its own shares in accordance with article L. 225-209-2 of the French Commercial Code

This resolution would authorize the Board of Directors to repurchase the Company's shares, under the conditions set forth in article L. 225-209-2 of the French Commercial Code.

The Company wishes to be able to use the shares repurchased pursuant to this authorization primarily to satisfy its obligations under equity incentive plans for the employees and corporate officers of the Company and its subsidiaries (such as RSUs and PSUs) as described in the description of the Company’s equity incentive plan set forth in Exhibit 4.1 “Description of Securities registered under Section 12 of the Securities Exchange Act of 1934” filed by the Company with its form 10-K/A on or around April 15, 2025 and/or as consideration for potential business acquisitions, but also for any other purpose that may be permitted from time to time by French law.

Under the Company's equity incentive plan, the Board of Directors wishes to have an option to deliver to employees and corporate officers, upon vesting, the repurchased shares of the Company instead of issuing new shares, which would limit future dilution for the Company's shareholders.

In addition, external growth and, in particular, acquisitions, are potential areas of development for the Company. The Board of Directors wishes to have the flexibility to repurchase outstanding shares in order to be able to use such shares as consideration for potential acquisitions, rather than issuing new shares.

The shareholders are also asked to approve the use of this authorization for any other purpose that would be permitted by law on the date on which the Board of Directors will use the authorization.

Share repurchases pursuant to this authorization cannot exceed 10% of the share capital, and share repurchases pursuant to this authorization for future use as consideration for potential external growth, merger, spin-off or contribution transaction cannot exceed 5% of the share capital. In any case, pursuant to French law, the Company cannot own, at any given time, more than 10% of the total of its own shares.

Any shares repurchased by the Company will not have voting rights nor rights to a dividend, for as long as they remain held by the Company.

Any share repurchases pursuant to this resolution shall be carried out within the price range of $6.76 to $31.50 per share (excluding fees and commissions), as determined by an independent expert (as required by article L. 225-209-2 of the French Commercial Code) and approved by the shareholders pursuant to this resolution. The aggregate cap on share repurchases pursuant to this resolution is $462,482,622 (excluding fees and commissions).

This authorization will be implemented under the conditions of article L. 225-209-2 of the French Commercial Code.

It will succeed to the authorization set forth in the 8^th resolution of the shareholders' meeting held on May 2, 2024 (which expired on May 1, 2025) and will be effective for a period of twelve (12) months from this Shareholders' Meeting.

TABLE OF CONTENTS

OVERVIEW - RESOLUTIONS / PROPOSALS 14 to 19

The Board of Directors proposes to the Shareholders' Meeting to renew, by adopting the proposed 14^th to 19^th resolutions, the delegations of competence granted to the Board of Directors by the shareholders' meetings held on June 8, 2023 and May 2, 2024 which are set to expire in August 2025.

Indeed, under French law, the issuance of new shares must be decided or authorized by the shareholders' meeting. Shareholders' meetings of French issuers generally decide to delegate to the board of directors the competence to decide such issuance of new shares in order to give to the board of directors the flexibility to issue new shares without having to convene a shareholders' meeting.

When the shareholders' meeting delegates to the board of directors the competence to decide several capital increases, it must set a global maximum amount for all capital increases which can be decided by the board of directors pursuant to any such delegations. The Board of Directors therefore proposes to this Shareholders' Meeting that all capital increases of the Company delegated under resolutions in proposals 14 to 19 be subject to a global limit of 1,468,198.84 euros (i.e., 50% of the Company's share capital) (the “Overall Cap”).

RESOLUTION / PROPOSAL 14

Delegation of competence to the Board of Directors to increase the Company's share capital by issuance of ordinary shares or other securities, with preferential subscription rights, up to 1,468,198.84 euros (representing 50% of the share capital), for a 26 month-period

This delegation would authorize the Board of Directors to issue new shares or other equity related securities to existing shareholders of the Company.

The Board of Directors therefore proposes to the Shareholders' Meeting to renew the delegation of competence given to the Board of Directors to decide the issuance of ordinary Company shares or other equity related securities, with preferential subscription rights in favor of existing shareholders, in France or abroad, in euros, in other currencies or monetary unit, for payment or free of charge. The capital increase(s) under this delegation will be carried out in favor of the Company's shareholders.

The aggregate nominal amount of all shares or other equity related securities which can be issued under such delegation (together with all other issuances made under the proposed 15^th to 19^th resolutions) may not exceed the Overall Cap.

The maximum nominal amount of debt securities, that may be issued, immediately and/or at maturity, by virtue of this delegation, may not exceed 2,000,000,000 euros (or the counter-value of this amount, if the issuance is made in another currency).

The sum owed or to be owed to the Company for each of the shares issued under this delegation shall be equal to or greater than the nominal value of the share on the issuance date of said securities.

The Board of Directors may not use this delegation during a public offering period if a tender offer is launched on the Company without prior authorization from the shareholders' meeting.

This delegation shall be granted for a period of twenty-six (26) months from the date of this Shareholders' Meeting and shall cancel and replace the delegation set forth in the 8^th resolution of the shareholders' meeting held on June 8, 2023.

This delegation would authorize the Board of Directors to issue new shares or other equity related securities to qualified investors or to a limited number of investors (as defined in article L. 411-2 1° of the French Monetary and Financial Code,) without shareholders' preferential subscription rights.

The Board of Directors therefore proposes to the Shareholders' Meeting to renew the delegation of competence given to the Board of Directors to decide the issuance of ordinary Company shares or other equity related securities, without shareholders' preferential subscription rights, by means of an offering made to a restricted number of investors or to qualified investors, in France or abroad, in euros, in other currencies or monetary unit, for payment or free of charge.

The aggregate nominal amount of all shares or other equity related securities which can be issued under such delegation may not exceed 20% of the Company's capital and will be charged against the Overall Cap.

Notwithstanding this change, the Company is proposing to retain a limit of 20%.

The maximum nominal amount of debt securities that may be issued, immediately and/or at maturity, by virtue of this delegation, shall not exceed 2,000,000,000 euros (or the counter-value of this amount, if the issuance is made in another currency).

COMPENSATION DISCUSSION AND ANALYSIS

This Compensation Discussion and Analysis (the “CD&A”) discusses our compensation policies and determinations that apply to our named executive officers (the “Named Executive Officers” or “NEOs”). When we refer to NEOs, we are referring to the following individuals whose 2024 compensation is set forth below in the Summary Compensation Table and subsequent compensation tables.


Name			Position
Jean-Marc Germain			Chief Executive Officer (“CEO”)
Jack Guo			Senior Vice President and Chief Financial Officer (“CFO”)
Ingrid Joerg			Executive Vice President and Chief Operating Officer President, Packaging, Automotive & Rolled Products business unit
Philippe Hoffmann			President, Aerospace & Transportation business unit
Ryan Jurkovic			Chief Human Resources Officer

While the discussion in the CD&A is focused on our NEOs, many of our executive compensation programs apply broadly to our executive officers and senior officers.

Executive Summary

Our Executive Compensation Philosophy

Our executive compensation philosophy rests on four pillars:

1)	Total Compensation Approach. Pay and rewards are considered in their totality.

2)	Differentiated Pay Based on Performance and Value Creation. Compensation is differentiated in a way that recognizes the value that each executive creates individually and collectively.

3)	Market Competitiveness. We use appropriate competitive data to inform, but not dictate, pay decisions.

Well-conceived Pay Positioning, Pay Mix and Award Allocation. We consider both internal equity and external market comparisons in setting total direct compensation; balance direct compensation components in a way that gives a competitive mix of cash and equity ownership, with higher percentages of equity the more senior the role; use a mix of metrics; and motivate executives to have an ownership mindset and to align with shareholder interests by providing them the opportunity to own Company stock.

2024 Business Highlights

2024 was a challenging year as the Company experienced demand weakness across most of its end markets along with extreme weather impacting operations in the US and Europe. Beginning in 2025, the Company became a voluntary domestic filer and began filing reports under the SEC’s U.S. domestic company forms. The Company filed its Annual Report on Form 10-K on February 28, 2025, which included audited financial statements prepared under U.S. GAAP and in U.S. dollars for the first time. Previously, the Company disclosed consolidated financials prepared under IFRS and in euros. In 2024, the Company had Adjusted EBITDA of $623 million and Free Cash Flow of $(100) million as disclosed in its Form 10-K and as prepared under U.S. GAAP. The Company's management's discussion and analysis of financial condition and results of operations, quantitative and qualitative disclosures about market risk, and financial statements for fiscal year 2024 can be found in Items 7, 7A, and 8, respectively, of the Company's Annual Report on Form 10-K.

TABLE OF CONTENTS

2024 Compensation Highlights

Consistent with our executive compensation philosophy and our performance in 2024, the elements of our direct compensation program for the NEOs and a summary of related compensation highlights for 2024 are set forth below.

Positive Pay Practices

The Company's executive compensation program reflects several positive pay governance practices, as follows:


What We Do			What We Don't Do
✔ Grant compensation that is primarily at-risk and variable			✘ Allow hedging or pledging of Company stock by directors or executive officers
✔ Subject annual cash incentives and PSUs to measurable and rigorous goals			✘ Reprice stock options
✔ Use an independent compensation consultant on an ad-hoc basis			✘ Provide excessive perquisites
✔ Cap annual cash incentive payments at 150% of target and PSUs at 200% of target			✘ Pay tax gross-ups on a change in control
✔ Structure compensation to avoid excessive risk taking			✘ Provide “single trigger” change in control payments
✔ Provide competitive compensation that is compared against industry peer groups			✘ Provide excessive severance benefits
✔ Maintain a robust clawback policy

Say-On-Pay

As a foreign private issuer, we are exempt from the proxy solicitation rules under Section 14 of the Exchange Act, including rules requiring a shareholder advisory vote to approve the compensation of our named executive officers (commonly referred to as the “Say-On-Pay vote”) in connection with a proxy solicitation.

How We Determine Executive Compensation

Oversight Responsibilities for Executive Compensation

The table below summarizes the key oversight responsibilities for executive compensation.


Board of Directors			• Approves the compensation philosophy, policies and structure with respect to the EPA and long-term equity incentive plan • Reviews and approves the performance and remuneration of our Chief Executive Officer on an annual basis
Human Resources Committee			• Reviews and make recommendations to the Board with respect to our compensation philosophy, policies and structure with respect to the EPA and long-term equity incentive plan • Reviews and recommends the corporate goals, performance and compensation structure of our Chief Executive Officer on an annual basis
Chief Executive Officer and Management			• Reviews and makes recommendations on the compensation structure of the Chief Executive Officer’s direct reports on an annual basis Management, including the Chief Executive Officer, develops preliminary recommendations regarding compensation matters with respect to all NEOs, other than the Chief Executive Officer, and provides these recommendations to the Human Resources Committee • Responsible for the administration of the compensation programs once Human Resources Committee decisions are finalized • Chief Executive Officer is not involved in any decision as to his own compensation

Use of Market Data

The Human Resources Committee approved a peer group of industry-relevant and similarly sized companies to be used for reference when making 2024 compensation decisions. Market comparison information for the CEO and CFO was sourced from publicly available peer group information. Market comparison information for our other NEOs was sourced from the Mercer Executive Remuneration survey for the manufacturing industry. For Ms. Joerg and Mr. Hoffmann, the Pan-European survey data for manufacturing industry was utilized; for Mr. Jurkovic, the US survey data for manufacturing industry was utilized. These data sources served as important reference points in assessing the competitiveness of base salary, incentive targets, and total direct compensation, as well as on overall market design practices.

For purposes of 2024 executive compensation decisions, the Human Resources Committee approved the following North American peer group.


2024 North American Compensation Peer Group
Alcoa Corporation	Commercial Metals Co.	Ryerson Holding Corp.
ATI Inc.	Crown Holdings, Inc.	Schnitzer Steel Industries, Inc.
Arconic Corp.	Kaiser Aluminum Corp.	Steel Dynamics, Inc.
Century Aluminum Co.	Novelis Inc.	Thor Industries, Inc.
Cleveland-Cliffs Inc.	Reliance, Inc.	Worthington Enterprises, Inc.

2024 Named Executive Officer Compensation

Base Salary

Base salaries for each Named Executive Officer are set taking into account such executive's qualifications, experience, and contributions. Base salaries are reviewed annually, and any adjustment is determined based on an assessment of corporate performance, the performance of each Named Executive Officer against his or her individual job and functional area's responsibilities, and competitive market conditions for executive compensation for similar positions. For and during 2024, base salaries were increased as follows, to reflect annual merit increases and to align with market:


Name	2023 Base Salary	2024 Base Salary	% Increase
Jean-Marc Germain	$1,115,000	$1,115,000	—
Jack Guo	$525,000	$540,000	3%
Ingrid Joerg⁽¹⁾	$945,804	$988,607	5%⁽²⁾
Philippe Hoffmann⁽¹⁾	$611,994	$656,235	7%⁽²⁾
Ryan Jurkovic	$520,000	$544,000	5%

(1)	Amounts converted to U.S. dollars from Swiss francs based on the average exchange rate of 1.1127 and 1.1363 in 2023 and 2024.

(2)	The percentage base salary increases reflected for Ms. Joerg and Mr. Hoffmann are partially driven by increase in average exchange rates. Ms. Joerg’s base salary increased by 2% (CHF 850,008 in 2023 to CHF 870,012 in 2024) and Mr. Hoffmann’s by 5% (CHF 550,008 in 2023 to CHF 577,512 in 2024).

Annual Cash Incentive Plan (the “EPA”)

Each of our NEOs participates in the Employee Performance Award (EPA) plan. The EPA is an annual cash bonus plan intended to provide performance-related award opportunities to employees contributing substantially to the success of the Company. Under the EPA, participants are provided opportunities to earn cash bonuses based on the level of achievement of certain financial, sustainability, and individual objectives as approved by our Human Resources Committee for the applicable annual performance period.

The three components of bonuses awarded under the EPA for 2024 had the following weights:

•	Financial Objectives⁽¹⁾⁽⁴⁾ — 65% (EPA Adjusted EBITDA⁽²⁾ (50%) and EPA Adjusted Free Cash Flow⁽³⁾ (15%))

•	Sustainability Objectives — 15% (Environmental, Health and Safety (“EHS”) (5%), Inclusion (5%), and Carbon Emissions (5%))

•	Individual Objectives — 20%

(1)

In 2024 and earlier years, the Company prepared consolidated audited financial statements solely under IFRS and euros. As such, the metrics used to set the 2024 EPA targets are based on the Company’s 2024 EPA Adjusted EBITDA and EPA Adjusted Free Cash Flow prepared under IFRS and presented in euros (as set forth in the following EPA table).

(2)

EPA Adjusted EBITDA is defined as income / (loss) from continuing operations before income taxes, results from joint ventures, net finance costs, other expenses and depreciation, amortization as adjusted to exclude restructuring costs, impairment charges, unrealized gains or losses on derivatives and on foreign exchange differences on transactions that do not qualify for hedge accounting, metal price lag, share-based compensation expense, non-operating gains / (losses) on pension and other post-employment benefits, expenses on factoring arrangements, effects of certain purchase accounting adjustments, start-up and development costs or acquisition, integration and separation costs, certain incremental costs and other exceptional, unusual or generally non-recurring items, and as may be further adjusted by the Company on an annual basis to remove the impact of certain one-off or non-recurring events.

(3)

EPA Adjusted Free Cash Flow is defined as net cash flow from operating activities, less capital expenditures, net of property, plant and equipment inflows excluding factoring impacts and may be further adjusted by the Company on an annual basis to remove the impact of certain one-off or non-recurring events.

(4)	The adjustments taken for EPA Adjusted EBITDA and EPA Adjusted Free Cash Flow are reviewed and approved by the Human Resources Committee. In fiscal year 2024 no additional adjustments were made.

Each component can be earned at 0% to 200% of target, however, the overall EPA payout is capped at 150% of target.

Financial Objectives. To promote synergies throughout the Company, the EPA is designed to encourage individual plants, business units and our corporate division to work closely together to achieve common strategic, operating and financial goals.

TABLE OF CONTENTS

For 2024, the Human Resources Committee chose EPA Adjusted EBITDA and EPA Adjusted Free Cash Flow as the financial objectives because it views these to be the best measures of the Company's performance in the short-term, with greater weighting on EPA Adjusted EBITDA due to its importance in measuring the profitability and financial performance of the Company’s operating segments. Below are the 2024 threshold, target, maximum and actual performance levels against these metrics:


Metric	Threshold (0% of target)	Target (100% of target)	Maximum (200% of target)	Actual	% Achievement (unweighted)
EPA Adjusted EBITDA⁽¹⁾	€665	€740	€815	€542.4	0%
EPA Adjusted Free Cash Flow⁽¹⁾	€60	€120	€180	€4.8	0%

(1)	In millions and rounded. As disclosed above, the figures in the table are based on the Company’s 2024 results reported in euros and prepared under IFRS.

If threshold performance is not achieved for a financial objective, there is no payout. Between threshold performance and target performance, payouts increase linearly from 0% to 100%. Achieving maximum performance level for a financial objective results in a payout of 200%, with payouts increasing linearly from 100% to 200% (subject to the overall EPA cap of 150% of target).

Sustainability Objectives. The sustainability objectives are divided into EHS (5%), inclusion (5%) and carbon emissions (5%) components. The EHS metric is measured quarterly at the Company, business unit or operating unit/site level, while inclusion and carbon emissions (scope 1 and carbon 2 emission) are measured annually at the Company level. Payout for sustainability objectives can range from 0% to 200% (subject to the overall EPA cap of 150% of target).

The EHS recordable case rate measures the number of fatalities, serious injuries, lost-time injuries, restricted work injuries, or medical treatments per 1 million hours worked, including by our contractors. The 2024 threshold, target and maximum for EHS were 1.98, 1.65 and 1.50 respectively. EHS recordable case rate is measured on a quarter-by-quarter basis with the resulting average of the four quarters calculated at year-end. For 2024, the unweighted achievement for EHS recordable case rate was 23%. For inclusion, the threshold, target and maximum were 23%, 24% and 25%. For carbon emissions, the threshold, target and maximum were 0.697, 0.632 and 0.615. The actuals for inclusion and carbon emissions were 24.9% and 0.659, resulting in unweighted achievement of 190% and 58.5%.

Individual Objectives. The individual objectives are evaluated annually via the performance management program (the “Performance Management Program”), and achievement against these objectives is used to determine the percentage attained of the individual objectives target. Payouts for individual objectives can range from 0% to 200% (subject to the overall EPA cap of 150% of target).

The individual objectives for 2024 were as follows:

•

Mr. Germain: Driving financial performance by delivering budget, driving sustainable Free Cash Flow generation, advancing the overall strategy with sustainability as a competitive advantage, strengthening the leadership pipeline for executive officer succession, and fostering growth in shareholder relations.

•	Mr. Guo: Executing the 2024 budget and financial objectives, refining M&A roadmap and strategy, driving high-value strategic initiatives, and advancing team development.

•	Ms. Joerg: Leading the strategic oversight of three business units, driving achievement of overall group financial performance and sustainability targets and developing leadership succession.

•	Mr. Hoffmann: Delivering 2024 budget and targeted operational performance while executing a long-term strategy to ensure the sustainable profitability of the A&T business.

•	Mr. Jurkovic: Implementing the human resources annual and strategic plan to enable business performance, driving talent and organizational development, executing rewards strategy and ensuring effective human resources governance.

Based on individual performance outcomes, the Human Resources Committee recommended the following payout percentages for the individual objectives component: Mr. Germain 100%; Mr. Guo 100%; Ms. Joerg 100%; Mr. Hoffmann 125%; and Mr. Jurkovic 100%.

Long-Term Equity Incentive Program

2024 Equity Grants

Equity grants are a critical component of our executive compensation strategy, designed to incentivize our executive officers and closely align their interests with those of our shareholders. Our 2024 annual long-term equity program consisted of restricted stock units (“RSUs”) and performance stock units (“PSUs”), with targeted weightings of approximately 35% and 65%, for RSUs and PSUs, respectively. Our targeted grant values are based on Constellium's 20-day average stock price prior to the grant date and differ from the grant date fair values used for accounting purposes that are reflected in the Summary Compensation Table and the Grants of Plan-Based Awards Table.


Award Type			Description / Objective
Restricted Stock Units			• Cliff vest on the third anniversary of the grant date, subject to continued service • Realized value linked to share price while supporting retention
Performance Stock Units			• Awarded to select executives to further incentivize performance • PSUs may be earned from 0% - 200% of target shares awarded based on achievement against three-year relative TSR goals • Performance is measured against the companies in the S&P MidCap 400 Materials Index and the S&P SmallCap 600 Materials Index • Earned units vest on the third anniversary of the grant date, subject to continued service

The performance schedule for the 2024 PSUs is summarized in the table below; provided that, if Constellium's Total Shareholder Return (“TSR”) is negative, the number of PSUs that can be earned is capped at 100% of target.


Constellium TSR			% of Target PSUs Earned
Below the average of the two 25th percentile TSRs of the comparator group			0%
Equal to the average of the two 25th percentile TSRs of the comparator group			25%
Between the average of the two 25th percentile TSRs and the average of the two median TSRs of the comparator group			25% - 100%, determined by linear interpolation
Equal to the average of the two median TSRs of the comparator group			100%
Between the average of the two median TSRs and the average of the two 75th percentile TSRs of the comparator group			100% - 200%, determined by linear interpolation
Equal to or above the average of the two 75th percentile TSRs of the comparator group			200%

2021-2024 PSUs

PSUs that were eligible to be earned based on three-year relative TSR performance from May 2021 to May 2024, against the same peer group and performance schedule as described above for the 2024 PSUs, were earned at 152% of target.

TABLE OF CONTENTS

Other Compensation and Governance Matters

Equity Grant Policies

Equity grants to executive officers currently are made pursuant to our Constellium SE 2013 Equity Incentive Plan. We do not coordinate the grant of equity awards to the timing of releases of material non-public information.

Share Ownership Guidelines (“SOGs”)

In 2018, we adopted Share Ownership Guidelines for our executive officers to encourage minimum levels of ownership and to foster alignment between the executive officers and shareholder interests. The Share Ownership Guidelines for our executive officers are as follows:


Position			Ownership Requirement (multiple of base salary)
Chief Executive Officer			4x
Chief Financial Officer and Business Unit Presidents			2x
All Other Executive Officers			1x

The SOGs give the executive officers five years to achieve guideline percentages. 50% of unvested RSUs count towards ownership, and unvested PSUs do not count toward ownership.

Employment Agreements and Termination Benefits

Constellium is party to employment agreements or offer letters with each of its NEOs. In general, Constellium may terminate its executive's employment or services for “cause” upon advance written notice, without compensation, for certain acts of the officer. Each executive officer may terminate his or her employment at any time upon advance written notice to Constellium. If the executive's employment or services is terminated by Constellium without “cause” or by the executive for “good reason,” the executive may be entitled to certain payments as provided by applicable laws or under the applicable employment agreement or offer letter. Except for the foregoing, our executives are not entitled to any severance payments upon the termination of their employment or services for any reason. See “Potential Payments Upon Termination or Change-In-Control” for further detail.

Retirement Benefits

Our U.S. based NEOs participate in a tax-qualified defined contribution 401(k) plan available to all our salaried employees. Additionally, a select group of highly compensated employees of Constellium US Holdings I, LLC and certain other subsidiaries and affiliates (including Messrs. Germain, Guo and Jurkovic) are eligible to participate in the Constellium US Holdings I, LLC U.S. Non-qualified Deferred Compensation and Restoration Plan (“DCRP”). The DCRP allows such employees to defer up to 85% of their EPA award. The DCRP is also a non-qualified restoration plan for employer contributions that cannot be made to our 401(k) plan due to the Code Section 401(a)(17) annual limit on compensation paid under a qualified plan. The restoration contribution equals 9% of total eligible 2024 pay (base salary plus bonus award paid in 2024) in excess of this limit. The 9% consists of the 6% employer matching contribution and the 3% non-elective retirement contribution. Employee EPA deferrals and employer restoration contributions are 100% vested.

Ms. Joerg and Mr. Hoffmann, who are based in Switzerland, participate in the Constellium Group Switzerland Pension Fund (Basic Plan) within FCT (Trianon Collective Foundation) and Constellium Group Switzerland Pension Fund (Plan 1e) within FCT 1e (Trianon Collective Foundation 1e). The Plan 1e generally operates similarly to a U.S. qualified defined contribution plan, and allows participants to choose their pension fund assets’ investment strategy. Both Constellium and the participants make contributions to the Plan 1e. Retirement benefits are only payable as a lump sum. Employer contributions to the Plan 1e are reflected within All Other Compensation in the Summary Compensation Table. Please see the 2024 Pension Benefits table for further information regarding the Basic Plan.

Other Benefits

We provide employees with benefits and perquisites based on competitive market conditions. All salaried employees, including the NEOs, receive healthcare coverage as well as life and disability insurance protection. Our NEOs (and some other executive officers) are also entitled to additional benefits, which may include a car allowance, parking, lunch allowance, company car, and tax services.

TABLE OF CONTENTS

Prohibition on Hedging and Pledging

We adopted an anti-hedging and pledging policy prohibiting directors and executive officers from engaging in hedging transactions and pledging of Constellium ordinary shares effective March 2025. For this purpose, a hedge means any financial instrument or derivative transaction, or trading strategy designed to hedge or offset any decrease in the market value of the Company's ordinary shares, such as a covered call, collar, prepaid variable forward sale contract, equity swap, exchange fund or similar transaction.

Clawback Policy

In November 2023, the Board approved a compensation clawback policy pursuant to, and consistent with, the listing requirements of the NYSE. The policy applies to certain members of the Company's current and former executive officers and provides for the mandatory recovery of certain erroneously awarded incentive-based compensation in the event that the Company is required to prepare an accounting restatement due to material noncompliance with any financial reporting requirement under the federal securities laws.

Compensation Risk Assessment

We believe our approach to compensation helps mitigate excessive risk-taking that could harm stockholder value or reward poor judgment by our executives. Our Human Resources Committee monitors and considers the risk mitigating factors when recommending executive compensation. The Company engaged an external compensation consultant to perform a compensation risk assessment. The compensation consultant noted that the current compensation plan provides for a balanced approach to delivering incentives and gave the company a low-risk rating. Based on such external review, the Human Resources Committee has concluded that the compensation program does not create risks that are reasonably likely to have a materially adverse effect on the Company or put the Company at risk.

HUMAN RESOURCES COMMITTEE REPORT

Our Human Resources Committee has reviewed and discussed the section entitled “Compensation Discussion and Analysis” with management. Based upon this review and discussion, the Human Resources Committee recommended to the Board of Directors that the section entitled “Compensation Discussion and Analysis” be included in this Proxy Statement.

(1)	Years of credited service represent seniority within Constellium. They do not affect the calculation of benefits under the Basic Plan.

(2)	The amounts in the table were calculated in Swiss francs and converted to U.S. dollars using the average exchange rate for 2024 (1 CHF to 1.1363 USD).

Ms. Joerg and Mr. Hoffmann participate in the Constellium Group Switzerland Pension Fund (Basic Plan) within FCT (Trianon Collective Foundation), a cash balance-based pension arrangement, under which Constellium contributes an annual amount on behalf of each participant based on such participant’s salary, bonus and age. Participants must also make contributions based on their salary, bonus and age. The annual post-retirement benefit under the Swiss Basic Pension Plan is calculated as a percentage of the accumulated capital in the Basic Plan for the employee at the time the employee retires. In the event the employee retires earlier than the regular retirement age of 65, the percentage is reduced. Subject to certain conditions, participants may elect to receive pension benefits entirely or partially in a lump sum; any funds taken as a lump sum reduce the remaining capital and, as a result, the amount of the annual payments. Because of the way benefits are calculated under the Basic Plan, it is not possible to express the pension benefits as a percentage of the last or an average salary.

None of the amounts in this column were previously reported in the Summary Compensation Table for prior fiscal years as this is the first year that Constellium has disclosed a Summary Compensation Table, however, a portion of the amounts in this column reflect executive and Company contributions for years prior to fiscal year 2024.

Earnings on amounts contributed to the DCRP, like our 401(k) plan, are based on participant selections among the deemed investment options selected by Constellium that are similar to those provided under the 401(k) plan. Benefits under the DCRP are unsecured and are general assets of Constellium. Participants are generally eligible to receive payment (or commence payment, as applicable) of their vested benefit as soon as practicable after July 1^st of the year following their year of termination, with respect to employee contributions, on or about July 1^st of the year specified by the participant, or at a later date if necessary to comply with Section 409A of the Internal Revenue Code. Participants may elect to receive their payments in a lump sum or in installments.

target and actual performance as of the change in control, and the converted cash obligations remain subject to continued service through the original vesting date, provided that if a participant is terminated without “cause” or for “good reason”) (as defined under the applicable award agreements), the cash obligations vest in full upon such termination.

Quantification of Payments upon Termination or Change in Control

The following table provides information regarding certain potential payments that would have been made to the NEOs if the triggering event occurred on December 31, 2024, given compensation and service levels as of that date and, where applicable, based on the closing market price per share of the Company's ordinary shares on the last trading day of the fiscal year ($10.27 on December 31, 2024). Amounts actually received upon the occurrence of a triggering event will vary based on factors such as the timing during the year of such event the market price of the Company's ordinary shares, and the officer's compensation level.

PAY RATIO

For the year ended December 31, 2024, the annual total compensation of Mr. Germain was $8,881,752 and the annual total compensation of the median employee was approximately $64,540. We estimate the resulting ratio of the annual total compensation of our CEO for 2024 to the median of the annual total compensation of all our employees (other than Mr. Germain) for 2024 to be 138:1. The ratio is calculated in a manner intended to be consistent with Item 402(u) of Regulation S-K.

In determining the median employee in 2024, we used December 31, 2024, as the determination date and the total cash compensation from our payroll records as our consistently applied compensation measure. We converted the pay for our non-U.S. employees to U.S. dollars. In accordance with the SEC rules, we excluded all employees in certain non-US jurisdictions that in total constituted less than 5% of our total headcount. The excluded employees were in Mexico (55 employees), China (256 employees) and Canada (99 employees). As of December 31, 2024, we had a total of 11,793 employees worldwide. We excluded 410 employees, resulting in an employee population of 11,382 for purposes of this computation.

The ratio presented above is a reasonable estimate calculated in a manner intended to be consistent with Item 402(u) of Regulation S-K. The SEC's rules for identifying the median employee and calculating the pay ratio based on that employee's annual total compensation allow companies to adopt a variety of methodologies, to apply certain exclusions, and to make reasonable estimates and assumptions that reflect their employee populations and compensation practices. As a result, the pay ratio reported by other companies may not be comparable to the pay ratio reported above, as other companies have different employee populations and compensation practices and may utilize different methodologies, exclusions, estimates, and assumptions in calculating their own ratios.

PAY VERSUS PERFORMANCE

The following table presents information about the relationship between executive “compensation actually paid” (or “CAP”) to the Company's principal executive officer (“PEO”) and non-PEO Named Executive Officers (the “Non-PEO NEOs”) and certain aspects of the financial performance of the Company. The Human Resources Committee does not utilize CAP as the basis for recommending compensation decisions to the Board of Directors. For further information concerning our compensation philosophy and how we align executive compensation with our performance, please see our “Compensation Discussion & Analysis.”

Cumulative TSR is calculated by dividing the sum of the cumulative amount of dividends for the measurement periods (beginning on December 31, 2021 and ending on December 31 of 2022, 2023, and 2024, respectively) determined in accordance with Item 402(v) of Regulation S-K, assuming dividend reinvestment, and the difference between Constellium’s ordinary share price at the end and the beginning of the measurement periods by Constellium’s ordinary share price at the beginning of the measurement period.

(6)	Reflects total shareholder return indexed to $100 for the S&P 600 Materials Index (“Peer Group TSR”), which is an industry line peer group reported for the year ended December 31, 2024, and assuming reinvestment of all dividends, where applicable.

We determined EPA Adjusted EBITDA is the “company-selected measure” (as previously defined). EPA Adjusted EBITDA is a non-GAAP measure and as previously disclosed in “Compensation Discussion and Analysis—Elements of Executive Compensation” was set in euros and under IFRS. For fiscal years 2024, 2023, and 2022, the EPA Adjusted EBITDA were respectively €542, €699 and €673 respectively. In fiscal year 2023, for the purposes of EPA payout calculations, an adjustment of €13.8 was made to the company EPA Adjusted EBITDA of €713, resulting in EPA Adjusted EBITDA of €699. The column reflects the EPA Adjusted EBITDA converted from EUR to USD using the average exchange rate for the respective years (1 euro to 1.0821 USD in fiscal year 2024; 1 euro to 1.0810 USD in FY23; and 1 euro to 1.507 USD in FY22). The rates are sourced from European Central Bank. The numbers as presented in the table use actual figures and not rounded figures.

NON- EXECUTIVE DIRECTOR COMPENSATION

The Human Resources Committee reviews the compensation of, and reimbursement policies for members of the Board. In reviewing non-executive director compensation, the Human Resources Committee considers market factors, general industry trends, and peer benchmarking with external compensation consultants.

For fiscal year 2024, non-executive director fees consisted of: (i) annual retainer fees, (ii) committee membership fees, (iii) committee chair fees, and (iv) cash paid in lieu of the former annual RSU grant. The revised fees remain within the overall limit of annual fixed fees of the non-executive directors which was approved by shareholders in 2021.

The non-executive director Board fees applicable for fiscal year 2024 were as follows:

Annual Retainer

•	an annual fee of $86,568 for each non-executive director

•	an additional annual fee of $54,105 for the Chairman of the Board

Audit Committee

•	an annual fee of $14,067 for members of the Audit Committee

•	an additional annual fee of $21,642 for the Chair of the Audit Committee

Human Resources Committee

•	an annual fee of $10,821 for members of the Human Resources Committee

•	an additional annual fee of $16,232 for the Chair of the Human Resources Committee

Nominating and Governance Committee

•	an annual fee of $9,739 for members of the Nominating and Governance Committee

•	an additional annual fee of $11,903 for the Chair of the Nominating and Governance Committee

Safety and Sustainability Committee

•	an annual fee of $9,739 for members of the Safety and Sustainability Committee

•	an additional annual fee of $11,903 for the Chair of the Safety and Sustainability Committee

Cash paid in lieu of the former annual RSU grant

•	annual cash of $190,000 for the Chairman of the Board

•	annual cash of $110,000 for our other non-executive directors

Upon the change in domicile to France, the equivalent of the RSU grant that had been previously granted on an annual basis was replaced with quarterly cash payments, starting in the third quarter of 2020, due to French law requirements. Cash payments in lieu of RSU grants are intended to be utilized by non-executive directors to purchase company stock.

The non-executive directors of the Board have not entered into any service contracts with the Company that provide either for benefits upon termination of employment or pension-related benefits.

In December 2021, as required by French law, two employees joined the Board as non-executive directors representing the employees, one of whom is based in Germany as a Sustainability Manager (designated to the Board by the European Works Council) and the other one in France as an Engineering Project Manager (designated to the Board by the French Group Works Council). The employee directors do not receive additional compensation as directors.

Share Ownership Guidelines for Non-Executive Directors

In 2019, we adopted SOGs for our non-executive directors to further encourage minimum levels of ownership and to foster additional alignment between the non-executive directors and shareholder interests (the SOGs do not apply to Mr. Verdier, Ms. Weiler and Mr. Blot, who do not receive compensation in respect of their services as non-executive directors).

In 2023, we raised the SOGs for our non-executive directors. They are required to hold $400,000 ($650,000 for the Chairman of the Board) in Constellium shares.

The SOGs give the non-executive directors five years to achieve guideline levels of ownership.

TABLE OF CONTENTS

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

The members of the Human Resources Committee--which has oversight over compensation matters--were Martha Brooks (Chair), Jean-Christophe Deslarzes, and Jean-Phillipe Puig. During fiscal year 2024, no member of the Human Resources Committee was an employee, officer, or former officer of Constellium SE or any of its subsidiaries or had any relationships requiring disclosure by us under the rules of the SEC with respect to certain relationships and related-party transactions. During fiscal year 2024, none of our executive officers served on the board of directors or compensation committee of any entity that had one or more of its executive officers serving on the Company's Board of Directors or Human Resources Committee.

AUDIT COMMITTEE REPORT

As the Audit Committee of the Board of Directors, we are composed of independent directors as required by, and in compliance with, the listing standards of the NYSE. We operate pursuant to a written Audit Committee charter adopted by the Board of Directors. Following is the report of the Audit Committee with respect to the Company's audited 2024 consolidated financial statements prepared under U.S. GAAP.

As set forth in the Audit Committee Charter, the Audit Committee is directly responsible for the appointment and retention of the independent auditors. The Audit Committee is directly responsible for the compensation and oversight of the work of the independent auditors (including resolution of disagreements between management and the independent auditors regarding financial reporting) for the purpose of preparing or issuing an audit report or related work. The independent auditors report directly to the Audit Committee.

It is not the duty of the Audit Committee to plan or conduct audits or to determine that the Company's financial statements and disclosures are complete and accurate and in accordance with U.S. GAAP or applicable rules and regulations. It is the responsibility of management to prepare the Company's financial statements and to develop and maintain adequate systems of internal accounting and financial controls.

In the absence of their possession of a reason to believe that such reliance is unwarranted, the members of the Audit Committee necessarily rely on the information or documentation provided to them by, and on the representations made by, management or other employees of the Company, the independent registered public accounting firm, and/or any consultant or professional retained by the Audit Committee, the Board of Directors, management or by any board committee. Accordingly, the Audit Committee's oversight does not provide an independent basis to determine that management has applied U.S. GAAP appropriately or maintained appropriate internal controls and disclosure controls and procedures designed to assure compliance with accounting standards and applicable laws and regulations. Furthermore, the audit committee's authority and oversight responsibilities do not independently assure that the audits of the financial statements have been carried out in accordance with the standards of the Public Company Accounting Oversight Board (United States) (the “PCAOB”) or that the financial statements are presented in accordance with U.S. GAAP.

Review with Management and Independent Registered Public Accounting Firm. The Audit Committee reviewed and discussed the audited consolidated financial statements for 2024 prepared under U.S. GAAP, with management and the Company's independent registered public accounting firm for 2024, PricewaterhouseCoopers. The Audit Committee also discussed with PricewaterhouseCoopers the matters required to be discussed by the applicable requirements of the PCAOB and the SEC, including, among other items, matters related to the conduct of the audit of the consolidated financial statements by the independent registered public accounting firm and its audit of the effectiveness of internal control over financial reporting pursuant to Section 404. PricewaterhouseCoopers provided to the audit committee the written disclosures and the letter required by the applicable requirements of the PCAOB regarding the independent accountant's communications with the audit committee concerning independence, and the Audit Committee discussed with PricewaterhouseCoopers the latter's independence, including whether its provision of non-audit services compromised such independence.

Conclusion of the Audit Committee. Based upon the reviews and discussions referred to above, the Audit Committee recommended that the Board of Directors include the audited consolidated financial statements in the Company's Annual Report on Form 10-K for the year ended December 31, 2024, as filed with the SEC on February 28, 2025.

Submitted by the Audit Committee of the Board of Directors:
