|--- | -----------------

Dear Jean-Marc:

We are pleased to make an offer of employment to you as Chief Executive Officer of Constellium N.V., a Netherlands naamloze vennootschap (the
Company), and its subsidiaries (collectively, the Constellium Group). Your official starting date will be a date to be mutually agreed by the parties (the Effective Date).

The following are the key points in our offer:

1. Term.
Your employment with Constellium Rolled Products Ravenswood, LLC (Ravenswood) shall begin on the Effective Date and shall continue until terminated in accordance with this employment letter (this Agreement, and
such term of employment, the Term). Although you will be appointed Chief Executive Officer of the Company as described in Section 2, you will be employed and your benefits will be administrated by Constellium Rolled Products
Ravenswood, LLC (Ravenswood).

2. Position and Duties.

(a) Position. Your appointment to the Board of Directors of the Company (the Board) as executive director shall be
proposed to the shareholders of the Company for vote at the annual general meeting of the Companys shareholders scheduled to be held in June 2016, and, subject to such shareholder approval, the Board will then promptly appoint you as the Chief
Executive Officer of the Company, effective as of the Effective Date. In this role, you shall report to the Board. Following the Effective Date, you and the Board will mutually agree as to whether you will be appointed as President (or any similar
role) of any subsidiary of the Company and whether you will serve as a member of the board of directors of any member of the Constellium Group (in addition to the Company) and any committees of any member of the Constellium Group.

(b) Duties. Subject to the ultimate authority of the Board, you will have full responsibility and management oversight control over the
business and strategic planning function of the Constellium Group. Your key responsibilities

will include, without limitation, reporting to the Board, meeting with the investment community, relationships with new and existing customers, stakeholders, and other external constituencies
(including governments), and such other duties that may be reasonably required or that may be reasonably requested by the Board from time to time (the Duties). You may delegate your powers to the extent required by the Duties and
good governance practices, and within the limits set out by applicable laws and regulations. You will be expected to devote substantially all of your working time to the Duties. In connection with the foregoing, the Board is aware that you currently
serve, and agrees that you may continue to serve during the Term, on the board of directors of each of the entities designated on a list provided by you to the Board in writing prior to the date hereof, so long as such entity does not compete with
the Constellium Group by carrying out any activity in the Business (as defined below) in any geography in which the Constellium Group carries out the Business. After the date hereof, you may not join the board of directors or similar body of any
other for-profit entity without the prior written consent of the Board.

(c) Location. You
will be based in an office located on the East Coast of the United States, but we expect you to spend a significant amount of time in Zurich, Switzerland, Paris, France, New York City, USA, Amsterdam, Netherlands, and the Constellium Groups
other operating sites.

3. Compensation.

(a) Base Salary. Your annual salary will be $950,000, payable on a biweekly basis in accordance with Ravenswoods normal payroll
practices in effect from time to time (the Base Salary). The Base Salary will be subject to review on an annual basis by the Board, commencing in or about April 2017.

(b) Annual Bonus. You will be eligible for an annual performance bonus pursuant to the terms and conditions of the Executive
Performance Award Plan (the EPA Plan), including the attainment of performance targets, established by the Board (or a committee thereof, including the Remuneration Committee) from time to time in its sole and absolute discretion
after consultation with you each year. Your target annual bonus will be 120% of your Base Salary (the Target Bonus). Your maximum annual bonus will be 180% of your Base Salary. Awards under the EPA Plan shall be paid after the
closing of the performance year with the first payroll after the Board (or a committee thereof, including the Remuneration Committee) has validated the financial results and the resulting payout. The EPA Plan is provided at the discretion of the
Company and is not a contractual entitlement. Participation in the EPA Plan in one year does not create a right to future participation in the EPA Plan. The Company reserves the right to amend the EPA Plan at its discretion at any time and for any
reason whatsoever. If you are terminated at any point during the year, your right to an EPA Plan award, if any, in respect of such year shall be determined in accordance with this Agreement and the applicable terms and conditions of the EPA Plan to
the extent consistent with this Agreement.

(to the extent remedy is reasonably possible, as determined by the Board).

(c) Resignation by You. You may resign your employment

occurs by operation of law; or

(vi) any material breach by the Company or any member of the Constellium Group of Section 3 of this
Agreement;

provided, however, that none of the events described in the foregoing clauses (i) through (vi) shall constitute Good Reason

(d) Notice of Termination. Any termination by the Company or by you shall be
communicated by Notice of Termination (as defined below) to the other party hereto. For purposes of this Agreement, a Notice of Termination means a written notice that (i) indicates the specific termination provision in this
Agreement relied upon, (ii) to the extent applicable, sets forth in reasonable detail the facts and circumstances claimed to provide a basis for termination of your employment under the provision so indicated, and (iii) if the Date of
Termination (as defined below) is other than the date of receipt of such notice, specifies the Date of Termination. The failure by the Company or by you to set forth in the Notice of Termination any fact or circumstance that contributes to a showing
of Cause or Good Reason, respectively, shall not waive any right of the Company or you hereunder or preclude the Company or you from asserting such fact or circumstance in enforcing the Companys or your rights hereunder.

(e) Date of Termination. For purposes of this Agreement, Date of Termination means (i) if your employment is
terminated by the Company with Cause, the date of receipt of the Notice of Termination by you or any later date specified therein; (ii) if your employment is terminated by you without Good Reason or by the Company without Cause, the date that

(f) Effect of Termination on Other Positions.
If, on the Date of Termination, you are a member of the Board or the board of directors of any member of the Constellium Group or you hold any other position with any member of the Constellium Group, you shall be deemed to have resigned from all
such positions as of the Date of Termination. You hereby agree to execute such documents and take such other actions as the Company may request to reflect such resignation.

competing entity, or otherwise) in the aluminum fabrication, packaging, or rolling business (the Business) in any location in which the Constellium Group conducts its operations and engages in the Business at the time of your
termination of employment.

(a) At Will Employment. The Company strives to treat all employees fairly and provide opportunity for personal growth to
the fullest extent possible. The Company is an at will employer; however, this does not guarantee continued employment. By definition, the term at will entitles either you and/or the Company to terminate your employment at
any time, with or without notice, and for any or no reason, with or without cause, subject to any obligations of the Company under Section 5 of this Agreement.

(b) Amendment. This Agreement may not be amended or modified otherwise than by a written agreement executed by the parties hereto or

upon you and your legal representatives, heirs, or legatees, and the Company and its successors and assigns.

(f) Severability. The
invalidity or unenforceability of any provision of this Agreement shall not affect the validity or enforceability of any other provision of this Agreement, and this Agreement shall be construed as if such invalid or unenforceable provision were
omitted (but only to the extent that such provision cannot be appropriately reformed or modified).

(g) Waiver of Breach. No waiver
by any party hereto of a breach of any provision of this Agreement by any other party, or of compliance with any condition or provision of this Agreement to be performed by such other party, shall operate or be construed as a waiver of any
subsequent breach by such other party of any similar or dissimilar provisions and conditions at the same or any prior or subsequent time. The failure of any party hereto to take any action by reason of such breach will not deprive such party of the
right to take action at any time while such breach continues.

(iii) Delayed Payment. Notwithstanding anything herein to the contrary, if you are a specified employee within the meaning

CONSTELLIUM N.V.

2016 PERFORMANCE-BASED RESTRICTED STOCK UNIT AGREEMENT

THIS 2016 PERFORMANCE-BASED RESTRICTED STOCK UNIT AGREEMENT (this Agreement), which contains the terms and conditions for
the Restricted Stock Units (Restricted Stock Units or Performance RSUs) referred to in the 2016 Performance-Based Restricted Stock Unit Award Letter delivered in hard copy or electronically to Participant (2016 Award
Letter), is by and between CONSTELLIUM N.V. (the Company), and the individual identified on the last page hereof (the Participant).

1. Grant of Performance RSUs. Subject to the terms and conditions of the Constellium N.V. 2013 Equity Incentive Plan, as amended and
restated from time to time (the Plan), this Agreement, and the 2016 Award Letter, the Company hereby grants to the Participant an award (the Award) of Performance RSUs shown in the 2016 Award Letter effective [●], 2016
(the Effective Date). The Award gives the Participant the opportunity to earn the right to receive the number of ordinary shares of the Company (the Target Number of Shares) equal to the Total Target Number of RSUs shown in
the 2016 Award Letter (the Target Number of Performance RSUs) if the Target Goal, as established by the Committee, is achieved by the Company over the Performance Period. These shares, together with any other shares that are transferable
under this Agreement, are referred to in this Agreement as Shares. Until the Shares vest and the Participant receives such Shares under the terms of Paragraph 6 below, the Participant shall have no rights as a shareholder of the Company
in respect of the Shares.

2. Incorporation of Plan and Acceptance of Documents. The Plan is incorporated by reference and all
terms used herein that are not defined in this Agreement (including the attached Appendix A) or in the 2016 Award Letter shall have the meaning set forth in the Plan. The Participant acknowledges that he or she has received a copy of, or has online
access to, the Plan, and hereby automatically accepts the Performance RSUs subject to all the terms and provisions of the Plan and this Agreement.

3. Committee Decisions and Interpretations: Committee Discretion. The Participant hereby agrees to accept as binding, conclusive, and
final all actions, decisions, and/or interpretations of the Committee, its delegates, or agents, upon any questions or other matters arising under the Plan or this Agreement.

4. Performance Measures: Number of Shares Payable to the Participant.

(a) Performance measures (as defined in Appendix A) established by the Committee are based on targeted levels of relative Total Shareholder
Return (TSR). The Committee establishes goals for Constellium TSR in respect of the Performance Period and the designated numbers of Shares that may be received by the Participant based upon the achievement of each goal during the
Performance Period, more fully described in Appendix A hereto. The number of Shares that may be received by the Participant if the Target Goal is reached is equal to the Target Number of Shares.



---

(b) The Performance RSUs awarded to the Participant and subject to this Agreement as reflected in
Paragraph 1 above represents the Participants opportunity to earn the Target Number of Shares upon (i) certification by the Committee that 100% of the Target Goal for TSR for the Performance Period has been met and (ii) satisfaction
of all the other conditions set forth in Paragraph 5 below.

(c) Subject to the Committees discretion as set forth in Subparagraph
4(d) below and to satisfaction of all other conditions set forth in Paragraph 5 below, the actual number of Shares earned by and transferable to Participant upon certification of TSR results and satisfaction of all other conditions set forth in
Paragraph 5 below may be increased or decreased depending on the level of TSR certified by the Committee at the end of the Performance Periods as set forth in Appendix A.

(d) Notwithstanding any other provision of this Agreement or the Plan, the Committee may in its sole and absolute discretion adjust, increase,
reduce, the number of Shares payable to the Participant based on such factors as it deems appropriate, including, but not limited to, the Companys performance.

5. Vesting.

(a)
Notwithstanding any other provision of this Agreement, the Participant shall not be entitled to any transfer of Shares under this Agreement unless and until the Participant satisfies applicable vesting conditions for such payment.

(b) Except as otherwise provided in Subparagraphs 5(c)  5(e) below and subject to the provisions of Subparagraph 4(d) above, the
Participant shall vest in Shares under this Agreement only if, and at the time that, both following conditions are fully satisfied:

(i) The Participant remains an active employee of the Company, any of its Subsidiaries or its Affiliates, through the third
anniversary of the Effective Date (the Maturity Date); and

(ii) The Committee certifies that the Company has
met TSR targets at least equal to or above the Threshold Goal. Certification of the performance achievement level, if any, by the Committee for each Performance Period shall be made yearly by each applicable anniversary of the Effective Date or as
soon thereafter as is administratively practicable.

(c) If the Participant qualifies for Retirement (as defined below) and the
Participants employment or consulting relationship with the Company terminates prior to the Maturity Date, and the Committee certifies that the performance measures for the Performance Period are satisfied under this Agreement, then upon such
certification, the Participant shall vest in that number of Shares the Participant would otherwise have received for the Performance Period, prorated to reflect that portion of the Performance Period prior to the Participants termination of
employment or consulting relationship with the Company.

The pro rata number of Shares in which the Participant shall become vested in
such case shall equal that number determined by multiplying (i) the number of Shares the Participant



-2-



---

would otherwise have received for the Performance Period in accordance with Paragraph 4 above times (ii) a fraction, the numerator of which is the number of full months in the period
that begins with the month that contains the Effective Date and ends with (and includes) the month in which the Participants employment or consulting relationship with the Company terminates due to the Participants Retirement, and the
denominator of which is the total number of full months in the period that begins with the month that contains the Effective Date and ends with the month that contains the Maturity Date.

For purposes of this Agreement, Retirement means the Participants retirement at the minimum age under legal statute or any
applicable contract required to be eligible for full retirement entitlements. However, the Committee may in its sole and absolute discretion adjust, increase or reduce, the number of Shares payable to the Participant based on such factors as it
deems appropriate.

(d) Subject to the sole and absolute discretion of the Committee, if the Participant dies, becomes disabled or
experiences a voluntary or involuntary termination of his/her services with the Company, any of its Subsidiaries or its Affiliates prior to the Maturity Date other than due to a Retirement (such date, the Separation Date), then no share
will vest.

(e) In the event of a Change in Control of the Company, all Performance RSUs held by the Participant under the Agreement shall
be deemed to be earned and vest in full and be free of restrictions and for the purposes hereof, the Target Goals shall be deemed to be reached at 100%, unless the Committee decides otherwise.

More generally, the Committee may in its sole and absolute discretion adjust, increase, reduce, the number of Shares payable to the
Participant based on such factors as it deems appropriate.

6. Conversion & Dividends.

(a) Upon conversion of Performance RSUs into Shares under this Agreement, such Performance RSUs shall be cancelled. Shares that become
transferable under this Agreement will be issued or purchased by the Company and transferred to the Participant, upon satisfaction of any required tax withholding obligations, if any, no later than March 15th of the year following the year in which
the Maturity Date occurs.

(b) The Company shall pay to the Participant a cash amount equal to the product of (x) all Dividends, if
any, paid on a Share from the Effective Date to the delivery date of the Shares as specified in Subparagraph 6(a) and (y) the number of Shares delivered to the Participant on such delivery date (including for this purpose any Shares that would
have been delivered on such delivery date but are withheld to satisfy tax withholding obligations).

7. Other Provisions.

(a) The Participant acknowledges that this Award and similar awards are made on a selective basis and are, therefore, to be kept confidential.

(b) Performance RSUs, Shares, and Participants interest in Performance RSUs and Shares, may
not be sold, assigned, transferred, pledged, or otherwise disposed of or encumbered at any time prior to both (i) the Participants becoming vested in Shares and (ii) the transfer of Shares under this Agreement. Further restrictions
as to resale of Shares delivered to the Participant under this Agreement may be imposed by applicable provisions of a sub-plan that the Participant may be subject to.

(c) If the Participant at any time forfeits any or all of the Performance RSUs pursuant to this Agreement, the Participant agrees that all of
the Participants rights and interest in such Performance RSUs and in Shares issuable thereunder shall terminate upon forfeiture without payment of consideration.

(d) The Committee shall determine whether an event has occurred resulting in the forfeiture of the Performance RSUs and any Shares issuable
thereunder in accordance with this Agreement and all determinations of the Committee shall be final and conclusive.

(e) The obligations
of the Company under this Agreement are unfunded and unsecured. Each Participant shall have the status of a general creditor of the Company with respect to amounts due, if any, under this Agreement.

(f) The parties to this Agreement intend that this Agreement meets the requirements of Section 409A of the Code and recognize that it may be
necessary to modify this Agreement and/or the Plan to reflect guidance under Section 409A of the Code issued by the Internal Revenue Service. Participant agrees that the Committee shall have sole discretion in determining (i) whether any such
modification is desirable or appropriate and (ii) the terms of any such modification.

(g) The Participant hereby automatically
becomes a party to this Agreement whether or not he or she accepts the Award electronically or in writing in accordance with procedures of the Committee, its delegates or agents.

(h) Nothing in this Agreement or the Plan shall interfere with or limit in any way the right of the Company, its Subsidiaries or an Affiliate
to terminate the Participants employment or service at any time, nor confer upon the Participant the right to continue in the employment of the Company and/or Affiliate.

8. Notices. All notices to the Company required hereunder shall be in writing and delivered by hand or by mail, addressed to
Constellium NV., Tupolevlaan 41 - 611119 NW SCHIPHOL RIJK, Attention: Marc Boone. Notices shall become effective upon their receipt by the Company if delivered in the foregoing manner.

9. Tax Consultation. The Participant understands he or she will incur tax consequences as a result of acquisition or disposition of the
Shares. The Participant agrees to consult with any tax consultants deemed advisable in connection with the acquisition of the Shares and acknowledges that he or she is not relying, and will not rely, on the Company for any tax advice.

APPENDIX A

1. Certain Definitions. For purposes of this Agreement:



| |  |  | The maximum number of Performance RSUs subject to this Award Agreement is 300% of the Target Number of Performance RSUs, of which up to 1/3 shall be eligible for vesting with respect to attainment of the Performance
Measure in each of the three Performance Periods (as such term is defined below) set forth below.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The Performance Measure is relative TSR (as such term is defined below) for each Performance Period, meaning a comparison of the Companys TSR against the Peer Groups TSR.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

2. Additional Definitions. For purposes of this Agreement:

(a) Annual Target Number of Performance RSUs means one third of the Target Number of Performance RSUs.

(b) Peer Group is defined with the three following components and means, in respect of the Annual Target Number of Performance
RSUs that may be earned for each Performance Period:

(i) For 33%, the Dow Jones Industrial Average (DJIA);

(ii) For 33%, the four following companies being direct peer group competitors of the Company: Alcoa,
Allegheny, Carpenter and Kaiser, as such list may be adjusted as described below; and

(iii) For 34%, the four following
main partners of the Company: Rio Tinto, Ball, Airbus and Ford.

When calculating the relative Total Shareholder Return, each
of the four companies listed in clauses (ii) and (iii) above shall have an equal relative weight to such group of companies of one fourth.

(c) Performance Period means each of the following three periods:



| | (i) | the one-year period commencing on the Effective Date and ending on the first anniversary of the Effective Date,
| | --- | ---------------------------------------------------------------------------------------------------------------



| | (ii) | the two-year period commencing on the Effective Date and ending on the second anniversary of the Effective Date, and
| | ---- | --------------------------------------------------------------------------------------------------------------------



| | (iii) | the three-year period commencing on the Effective Date and ending on the third anniversary of the Effective Date.
| | ----- | -----------------------------------------------------------------------------------------------------------------



A-1



---

(d) Total Shareholder Return or TSR means (i) total shareholder
return as applied to the Company or any company in the Peer Groups, meaning stock price appreciation from the beginning to the end of the Performance Period, plus dividends and distributions made or declared during the Performance Period, expressed
as a percentage return, and (ii) with respect to the DJIA, the variation of the DJIA index from the beginning to the end of the Performance Period, expressed as a percentage of the beginning point.

For purposes of computing the TSR, the stock price at the beginning of the Performance Period will be the average closing price of a share of
common stock of the Company over the 20 trading days ending on the first day of the Performance Period and the stock price at the end of the Performance Period will be the average closing price of a share of common stock of the Company over the 20
trading days ending on the last day of the Performance Period, adjusted for changes in capital structure as set forth in the Plan or as determined at the discretion of the Committee.

The same rules described above will apply to the Peer Group.

3. Calculation. The number of Shares earned under this Agreement for each Performance Period will be calculated each year following the
applicable anniversary date as follows:

FIRST: Determine the TSR for the Company, for each other company in the Peer Group, and the
DJIA for the Performance Period.

SECOND: Compare the Companys TSR against the average Peer Group TSR.

THIRD: Apply the following principles to determine if the following target goals (Target Goals) are achieved:

If, for a given Performance Period, the Companys TSR is below the average of the Peer Groups TSR (the Threshold Goal),
then no Performance RSUs shall vest and no Shares shall be earned by the Participant in respect of that Performance Period;

If, for a
given Performance Period, the Companys TSR is equal to the average of the Peer Groups TSR, then 100% of the Annual Target Number of Performance RSUs shall vest and the corresponding number of Shares shall be earned by the Participant in
respect of that Performance Period, subject always to his or her complying with the service-based vesting conditions at the end of the three year period as set forth in Paragraph 5(b) of this Agreement;

If, for a given Performance Period, the Companys TSR is above the average of the Peer Group TSR, then:



| | (i) | 100% of the Annual Target Number of Performance RSUs shall vest and,
| | --- | --------------------------------------------------------------------



| | (ii) | an amount of additional Performance RSUs equal to twice of the excess of the Companys TSR over the average of the Peer Group TSR shall vest (e.g., if the Company TSR exceeds the Peer Group TSR by 3%, an
additional 6% of the Annual Target Number of Performance RSUs shall vest).
| | ---- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

4. Rules. The following rules apply to the computation of the number of Performance RSUs earned:

(a) For a given Performance Period, the maximum number of Performance RSUs that may be earned is 300% of the Annual Target Number of
Performance RSUs.

(b) Companies shall be removed from the peer group competitor and main partner components of
the Peer Group if they undergo a Specified Corporate Change (as defined below). A company that is removed from the Peer Group before the measurement date will not be included at all in the computation of the performance factor. A company in the Peer
Group will be deemed to have undergone a Specified Corporate Change if it:



| | 1. | permanently ceases to be a publicly traded company on a national stock exchange or market system; or
| | -- | ----------------------------------------------------------------------------------------------------



| | 2. | has been acquired by another company (but not including internal reorganizations, in which case the resulting public company will be deemed a member of the Peer Group), or has sold all or substantially all of its
assets.
| | -- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The Company shall rely on press releases, public filings, website postings, and other reasonably reliable
information available regarding a company that is a member of the Peer Group in making a determination as to whether a Specified Corporate Change has occurred.

|Dividend Equivalents: |  | On each Delivery Date, the Company shall pay to the Participant a cash amount equal to the product of (x) all cash dividends or other distributions (other than cash dividends or other distributions pursuant to which
the RSUs were adjusted pursuant to Section 3(c) of the Plan), if any, paid on a Share from the Grant Date to such Delivery Date and (y) the number of Shares delivered to the Participant on such Delivery Date (including for this purpose any
Shares that would have been delivered on such Delivery Date but for being withheld to satisfy tax withholding obligations).

All other terms of the RSUs shall be as set forth in the Plan, and the Plan is incorporated herein by
reference. The Award Agreement and the Plan constitute the entire agreement and understanding of the parties with respect to the RSUs. In the event that any provision of the Award Agreement is inconsistent with the Plan, the terms of the Plan shall
