 EXHIBIT 10.5 

FORM OF AMENDED AND RESTATED INDEMNIFICATION AGREEMENT 

This Amended and Restated Indemnification Agreement (“Agreement”) is made as of August 1, 2017 and was originally effective as
of November 1, 2016 (the “Effective Date”), by and between Alcoa Corporation, a Delaware corporation (the “Company”), and
                     (“Indemnitee”). Except as provided herein, this Agreement supersedes and replaces any and all previous
Agreements between the Company and Indemnitee covering the subject matter of this Agreement. 
 RECITALS 

WHEREAS, the Board of Directors of the Company (the “Board”) believes that highly competent persons have become more reluctant to
serve publicly-held corporations as directors or officers or in other capacities unless they are provided with adequate protection through insurance or adequate indemnification against inordinate risks of claims and actions against them arising out
of their service to and activities on behalf of the corporation; 
 WHEREAS, the Board has determined that the increased difficulty in
attracting and retaining such persons is detrimental to the best interests of the Company and its stockholders and that the Company should act to assure such persons that there will be increased certainty of such protection in the future; 

WHEREAS, the Amended and Restated Bylaws of the Company (the “Bylaws”) require indemnification of the officers and directors of the
Company, and Indemnitee may also be entitled to indemnification pursuant to the General Corporation Law of the State of Delaware (the “DGCL”); however, the Bylaws and the DGCL expressly provide that the indemnification provisions set forth
therein are not exclusive, and thereby contemplate that contracts may be entered into between the Company and members of the board of directors, officers and other persons with respect to indemnification; 

WHEREAS, the Board has determined that, in order to attract and retain qualified individuals, the Company will attempt to maintain on an
ongoing basis, at its sole expense, liability insurance to protect persons serving the Company and its subsidiaries from certain liabilities; 

WHEREAS, it is reasonable, prudent and necessary for the Company contractually to obligate itself to indemnify, and to advance expenses on
behalf of, such persons to the fullest extent permitted by applicable law so that they will serve or continue to serve the Company free from undue concern that they will not be so indemnified; and 

WHEREAS, Indemnitee may not be willing to serve or continue to serve as an officer or director without the supplemental protections and
indemnifications afforded to it under this Agreement. 
 NOW, THEREFORE, in consideration of the premises and the covenants contained
herein, the Company and Indemnitee do hereby covenant and agree as follows: 







 Section 1.    Services to the Company. Indemnitee agrees to serve
as a director or officer of the Company or as an agent of the Company. Indemnitee may at any time and for any reason resign from such position (subject to any other contractual obligation or any obligation imposed by operation of law), in which
event the Company shall have no obligation under this Agreement to continue Indemnitee in such position. This Agreement shall not be deemed an employment contract between the Company (or any of its subsidiaries or any Enterprise) and Indemnitee.
Indemnitee specifically acknowledges that if Indemnitee is employed with the Company (or any of its subsidiaries or any Enterprise), such employment relationship is at will, and the Indemnitee may be discharged at any time for any reason, with or
without cause, except as may be otherwise provided in any written employment contract between Indemnitee and the Company (or any of its subsidiaries or any Enterprise), other applicable formal severance policies duly adopted by the Board, or, with
respect to service as a director or officer of the Company, by the Amended and Restated Certificate of Incorporation of the Company (the “Certificate of Incorporation”), the Bylaws and the DGCL. The foregoing notwithstanding, this
Agreement shall continue in force after Indemnitee has ceased to serve as a director, officer or agent of the Company as provided in Section 16 hereof. 

Section 2.    Definitions. As used in this Agreement: 

(a)    References to “agent” shall mean any person who is or was a director, officer, or employee of the Company
or a subsidiary of the Company or other person authorized by the Company to act for the Company, to include such person serving in such capacity as a director, officer, employee, fiduciary or other official of another corporation, partnership,
limited liability company, joint venture, trust or other enterprise at the request of, for the convenience of, or to represent the interests of the Company or a subsidiary of the Company. 

(b)    A “Change in Control” shall be deemed to occur upon the earliest to occur after the date of this
Agreement of any of the following events: 
 i.    Acquisition of Stock by Third Party. Any one person or more than one
person acting as a group (a “Person”) acquires, whether by purchase in the market, tender offer, reorganization, merger, statutory share exchange or consolidation, other similar transaction involving the Company or any of its
subsidiaries or otherwise (a “Transaction”), common stock of the Company possessing 30% or more of the total voting power of the stock of the Company unless (A) all or substantially all of the individuals and entities that were
the beneficial owners of the then-outstanding shares of common stock of the Company (the “Outstanding Company Common Stock”) or the combined voting power of the then outstanding voting securities of the Company (the
“Outstanding Company Voting Securities”) immediately prior to such Transaction own, directly or indirectly, 50% or more of the then outstanding shares of common stock (or, for a non-corporate
entity, equivalent securities) and the combined voting power of the then-outstanding voting securities entitled to vote generally in the election of directors (or, for a non-corporate entity, equivalent governing body), as the case may be, of the
entity resulting from such Transaction (including, without limitation, an entity that, as a result of such transaction, owns the Company or all or substantially all of the Company’s assets either directly or through one or more subsidiaries) in
substantially the same proportions as their ownership immediately prior to such Transaction of the Outstanding Company Common Stock and the Outstanding 

  
 -2- 








 
Company Voting Securities, as the case may be, and (B) at least a majority of the members of the board of directors (or, for a non-corporate entity,
equivalent governing body) of the entity resulting from such Transaction were members of the Board at the time of the Transaction (which in the case of a market purchase shall be the date 30% ownership was first acquired, in the case of a tender
offer, when at least 30% of the Company’s shares were tendered, and in other events upon the execution of the initial agreement or of the action of the Board providing for such Transaction); and provided, further, that, for purposes of this
paragraph, the following acquisitions shall not constitute a Change in Control: (A) any acquisition directly from the Company, (B) any acquisition by the Company, or (C) any acquisition by any employee benefit plan (or related trust)
sponsored or maintained by the Company or any Affiliate; 
 ii.    Change in Board of Directors. A majority of the
members of the Board is replaced during any 12-month period by (A) directors whose appointment or election is not endorsed by a majority of the Board before the date of such appointment or election and/or
(B) whose appointment or election is in connection with an election contest or through use of proxy access procedures included in the Company’s organizational documents; 

iii.    Corporate Transactions. Any Person acquires (or has acquired during the
12-month period ending on the date of the most recent acquisition by such Person) assets of the Company that have a total gross fair market value of more than 40% of the total gross fair market value of all of
the assets of the Company immediately before such acquisition or acquisitions; or 
 iv.    Liquidation. The
consummation of a complete liquidation or dissolution of the Company. 
 Further and for the avoidance of doubt, a transaction will not constitute a Change
in Control if its sole purpose is to (i) change the jurisdiction of the Company’s incorporation, or (ii) create a holding company that will be owned in substantially the same proportions by the persons who held the Company’s
securities immediately before such transaction.     
 Provided, however, solely with respect to any amounts that the Committee
determines to be subject to Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”), (and not excepted therefrom), and a Change in Control is a distribution event for purposes of such amounts, the foregoing
definition of Change in Control shall be interpreted, administered, limited and construed in a manner necessary to ensure that the occurrence of any such event shall result in a Change in Control only if such event qualifies as a change in the
ownership or effective control of a corporation, or a change in the ownership of a substantial portion of the assets of a corporation, as applicable, within the meaning of Treasury Regulation
Section 1.409A-3(i)(5). 
 (c)    “Corporate Status” describes
the status of a person who is or was a director, officer, employee or agent of the Company or of any other corporation, limited liability company, partnership or joint venture, trust or other enterprise which such person is or was serving at the
request of the Company. 

  
 -3- 








 (d)    “Disinterested Director” shall mean a director of the
Company who is not and was not a party to the Proceeding in respect of which indemnification is sought by Indemnitee. 

(e)    “Enterprise” shall mean the Company and any other corporation, limited liability company, partnership,
joint venture, trust or other enterprise of which Indemnitee is or was serving at the request of the Company as a director, officer, trustee, partner, managing member, employee, agent or fiduciary. 

(f)    “Expenses” shall include all reasonable attorneys’ fees, retainers, court costs, transcript costs,
fees of experts and other professionals, witness fees, travel expenses, duplicating costs, printing and binding costs, telephone charges, postage, delivery service fees, any federal, state, local or foreign taxes imposed on Indemnitee as a result of
the actual or deemed receipt of any payments under this Agreement, ERISA excise taxes and penalties, and all other disbursements or expenses of the types customarily incurred in connection with prosecuting, defending, preparing to prosecute or
defend, investigating, being or preparing to be a witness in, or otherwise participating in, a Proceeding. Expenses also shall include (i) Expenses incurred in connection with any appeal resulting from any Proceeding, including without
limitation the premium, security for, and other costs relating to any cost bond, supersedeas bond, or other appeal bond or its equivalent, and (ii) for purposes of Section 14(d) only, Expenses incurred by Indemnitee in connection with the
interpretation, enforcement or defense of Indemnitee’s rights under this Agreement, by litigation or otherwise. Expenses, however, shall not include amounts paid in settlement by Indemnitee or the amount of judgments or fines against
Indemnitee. 
 (g)    “Independent Counsel” shall mean a law firm, or a member of a law firm, that is
experienced in matters of corporation law and neither presently is, nor in the past three years has been, retained to represent: (i) the Company or Indemnitee in any matter material to either such party (other than with respect to matters
concerning the Indemnitee under this Agreement, or of other indemnitees under similar indemnification agreements), or (ii) any other party to the Proceeding giving rise to a claim for indemnification hereunder. Notwithstanding the foregoing,
the term “Independent Counsel” shall not include any person who, under the applicable standards of professional conduct then prevailing, would have a conflict of interest in representing either the Company or Indemnitee in an action to
determine Indemnitee’s rights under this Agreement. 
 (h)    The term “Proceeding” shall include any
threatened, pending or completed action, suit, claim, counterclaim, cross claim, arbitration, mediation, alternate dispute resolution mechanism, investigation, inquiry, administrative hearing or any other actual, threatened or completed proceeding,
whether brought in the right of the Company or otherwise and whether of a civil, criminal, administrative, legislative or investigative (formal or informal) nature, including any appeal therefrom, in which Indemnitee was, is or will be involved as a
party, potential party, non-party witness or otherwise by reason of the fact that Indemnitee is or was a director or officer of the Company, by reason of any action taken by Indemnitee (or a failure to take
action by Indemnitee) or of any action (or failure to act) on Indemnitee’s part while acting pursuant to Indemnitee’s Corporate Status, in each case whether or not serving in such capacity at the time


  
 -4- 








 
any liability or Expense is incurred for which indemnification, reimbursement or advancement of Expenses can be provided under this Agreement. 

(i)    Reference to “other enterprise” shall include employee benefit plans; references to “fines”
shall include any excise tax assessed with respect to any employee benefit plan; references to “serving at the request of the Company” shall include any service as a director, officer, employee or agent of the Company which imposes duties
on, or involves services by, such director, officer, employee or agent with respect to an employee benefit plan, its participants or beneficiaries; and a person who acted in good faith and in a manner Indemnitee reasonably believed to be in the best
interests of the participants and beneficiaries of an employee benefit plan shall be deemed to have acted in a manner “not opposed to the best interests of the Company” as referred to in this Agreement. 

Section 3.    Indemnity in Third-Party Proceedings. The Company shall indemnify Indemnitee in accordance with
the provisions of this Section 3 if Indemnitee is, or is threatened to be made, a party to or a participant in any Proceeding, other than a Proceeding by or in the right of the Company to procure a judgment in its favor, by reason of
Indemnitee’s Corporate Status. Pursuant to this Section 3, Indemnitee shall be indemnified to the fullest extent permitted by applicable law against all Expenses, judgments, fines and amounts paid in settlement (including all interest,
assessments and other charges paid or payable in connection with or in respect of such Expenses, judgments, fines and amounts paid in settlement) actually and reasonably incurred by Indemnitee or on Indemnitee’s behalf in connection with such
Proceeding or any claim, issue or matter therein, if Indemnitee acted in good faith and in a manner Indemnitee reasonably believed to be in or not opposed to the best interests of the Company and, in the case of a criminal Proceeding had no
reasonable cause to believe that Indemnitee’s conduct was unlawful. The parties hereto intend that this Agreement shall provide to the fullest extent permitted by law for indemnification in excess of that expressly permitted by statute,
including, without limitation, any indemnification provided by the Certificate of Incorporation, the Bylaws, vote of its stockholders or Disinterested Directors or applicable law. 

Section 4.    Indemnity in Proceedings by or in the Right of the Company. The Company shall indemnify
Indemnitee in accordance with the provisions of this Section 4 if Indemnitee is, or is threatened to be made, a party to or a participant in any Proceeding by or in the right of the Company to procure a judgment in its favor by reason of
Indemnitee’s Corporate Status. Pursuant to this Section 4, Indemnitee shall be indemnified to the fullest extent permitted by applicable law against all Expenses actually and reasonably incurred by Indemnitee or on Indemnitee’s behalf
in connection with such Proceeding or any claim, issue or matter therein, if Indemnitee acted in good faith and in a manner Indemnitee reasonably believed to be in or not opposed to the best interests of the Company. No indemnification for Expenses
shall be made under this Section 4 in respect of any claim, issue or matter as to which Indemnitee shall have been finally adjudged by a court to be liable to the Company, unless and only to the extent that the Delaware Court (as hereinafter
defined) or any court in which the Proceeding was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, Indemnitee is fairly and reasonably entitled to indemnification.


  
 -5- 








 Section 5.    Indemnification for Expenses of a Party Who is Wholly
or Partly Successful. Notwithstanding any other provisions of this Agreement, to the fullest extent permitted by applicable law and to the extent that Indemnitee is a party to (or a participant in) and is successful, on the merits or otherwise,
in any Proceeding or in defense of any claim, issue or matter therein, in whole or in part, the Company shall indemnify Indemnitee against all Expenses actually and reasonably incurred by Indemnitee in connection therewith. If Indemnitee is not
wholly successful in such Proceeding but is successful, on the merits or otherwise, as to one or more but less than all claims, issues or matters in such Proceeding, the Company shall indemnify Indemnitee against all Expenses actually and reasonably
incurred by Indemnitee or on Indemnitee’s behalf in connection with or related to each successfully resolved claim, issue or matter to the fullest extent permitted by law. For purposes of this Section and without limitation, the termination of
any claim, issue or matter in such a Proceeding by dismissal, with or without prejudice, shall be deemed to be a successful result as to such claim, issue or matter. 

Section 6.    Indemnification For Expenses of a Witness. Notwithstanding any other provision of this
Agreement, to the fullest extent permitted by applicable law and to the extent that Indemnitee is, by reason of Indemnitee’s Corporate Status, a witness or otherwise asked to participate in any Proceeding to which Indemnitee is not a party,
Indemnitee shall be indemnified against all Expenses actually and reasonably incurred by Indemnitee or on Indemnitee’s behalf in connection therewith. 

Section 7.    Partial Indemnification. If Indemnitee is entitled under any provision of this Agreement to
indemnification by the Company for some or a portion of Expenses, but not, however, for the total amount thereof, the Company shall nevertheless indemnify Indemnitee for the portion thereof to which Indemnitee is entitled. 

Section 8.    Additional Indemnification. 

(a)    Notwithstanding any limitation in Sections 3, 4, or 5, the Company shall indemnify Indemnitee to the fullest extent
permitted by applicable law if Indemnitee is a party to or threatened to be made a party to any Proceeding (including a Proceeding by or in the right of the Company to procure a judgment in its favor) by reason of Indemnitee’s Corporate Status.

 (b)    For purposes of Section 8(a), the meaning of the phrase “to the fullest extent permitted by
applicable law” shall include, but not be limited to: 
 i.    to the fullest extent permitted by the provision of
the DGCL that authorizes or contemplates additional indemnification by agreement, or the corresponding provision of any amendment to or replacement of the DGCL, and 

ii.    to the fullest extent authorized or permitted by any amendments to or replacements of the DGCL adopted after the
date of this Agreement that increase the extent to which a corporation may indemnify its officers and directors. 

Section 9.    Exclusions. Notwithstanding any provision in this Agreement, the Company shall not be obligated
under this Agreement to make any indemnification payment in connection with any claim involving Indemnitee: 

  
 -6- 








 (a)    for which payment has actually been made to or on behalf of Indemnitee
under any insurance policy or other indemnity provision, except with respect to any excess beyond the amount paid under any insurance policy or other indemnity provision; or 

(b)    for (i) an accounting of profits made from the purchase and sale (or sale and purchase) by Indemnitee of
securities of the Company within the meaning of Section 16(b) of the Exchange Act (as defined in Section 2(b) hereof) or similar provisions of state statutory law or common law, (ii) any reimbursement of the Company by the Indemnitee
of any bonus or other incentive-based or equity-based compensation or of any profits realized by the Indemnitee from the sale of securities of the Company, as required in each case under the Exchange Act (including any such reimbursements that arise
from an accounting restatement of the Company pursuant to Section 304 of the Sarbanes-Oxley Act of 2002 (the “Sarbanes-Oxley Act”), or Section 904 of the Dodd-Frank Wall Street Reform and Consumer Protection Act, or the payment
to the Company of profits arising from the purchase and sale by Indemnitee of securities in violation of Section 306 of the Sarbanes-Oxley Act) or (iii) any reimbursement of the Company by Indemnitee of any compensation pursuant to any
compensation recoupment or clawback policy adopted by the Board or the compensation committee of the Board, including but not limited to any such policy adopted to comply with stock exchange listing requirements implementing Section 10D of the
Exchange Act; or 
 (c)    except as provided in Section 14(d) of this Agreement, in connection with any Proceeding
(or any part of any Proceeding) initiated by Indemnitee, including any Proceeding (or any part of any Proceeding) initiated by Indemnitee against the Company or its directors, officers, employees or other indemnitees, unless (i) the Board
authorized the Proceeding (or any part of any Proceeding) prior to its initiation or (ii) the Company provides the indemnification, in its sole discretion, pursuant to the powers vested in the Company under applicable law. 

Section 10.    Advances of Expenses. Notwithstanding any provision of this Agreement to the contrary (other
than Section 14(d)), the Company shall advance, to the extent not prohibited by law, the Expenses incurred and paid by Indemnitee in connection with any Proceeding (or any part of any Proceeding) not initiated by Indemnitee or any Proceeding
initiated by Indemnitee with the prior approval of the Board as provided in Section 9(c), and such advancement shall be made within twenty (20) days after the receipt by the Company of a statement or statements requesting such advances
from time to time, whether prior to or after final disposition of any Proceeding. Advances shall be unsecured and interest free. Advances shall be made without regard to Indemnitee’s ability to repay the Expenses and without regard to
Indemnitee’s ultimate entitlement to indemnification under the other provisions of this Agreement. In accordance with Section 14(d), advances shall include any and all reasonable Expenses incurred pursuing an action to enforce this right
of advancement, including Expenses incurred preparing and forwarding statements to the Company to support the advances claimed. The Indemnitee shall qualify for advances upon the execution and delivery to the Company of this Agreement, which shall
constitute an undertaking providing that the Indemnitee undertakes to repay the amounts advanced (without interest) to the extent that it is ultimately determined that Indemnitee is not entitled to be indemnified by the Company. No other form of
undertaking shall be required other than the execution of this Agreement, except as may be expressly required 

  
 -7- 








 
by the DGCL. This Section 10 shall not apply to any claim made by Indemnitee for which indemnity is excluded pursuant to Section 9. 

Section 11.    Procedure for Notification and Defense of Claim. 

(a)    Indemnitee shall notify the Company in writing of any matter with respect to which Indemnitee intends to seek
indemnification or advancement of Expenses hereunder as soon as reasonably practicable following the receipt by Indemnitee of written notice thereof. The written notification to the Company shall include a description of the nature of the Proceeding
and the facts underlying the Proceeding. To obtain indemnification under this Agreement, Indemnitee shall submit to the Company a written request, including therein or therewith such documentation and information as is reasonably available to
Indemnitee and is reasonably necessary to determine whether and to what extent Indemnitee is entitled to indemnification following the final disposition of such Proceeding. The omission by Indemnitee to notify the Company hereunder will not relieve
the Company from any liability which it may have to Indemnitee hereunder or otherwise than under this Agreement except to the extent that such delay materially and adversely affects the Company’s ability to participate in the defense of such
Proceeding, and any delay in so notifying the Company shall not constitute a waiver by Indemnitee of any rights under this Agreement. The Secretary of the Company shall, promptly upon receipt of such a request for indemnification, advise the Board
in writing that Indemnitee has requested indemnification. 
 (b)    The Company will be entitled to participate in the
Proceeding at its own expense and, except as otherwise provided below, to the extent the Company so wishes, it may assume the defense thereof with counsel reasonably satisfactory to Indemnitee. After notice from the Company to Indemnitee of its
election to assume the defense of any such Claim, the Company shall not be liable to Indemnitee under this Agreement or otherwise for any Expenses subsequently directly incurred by Indemnitee in connection with Indemnitee’s defense of such
Claim other than reasonable costs of investigation or as otherwise provided below. Indemnitee shall have the right to employ its own legal counsel in such Claim, but all Expenses related to such counsel incurred after notice from the Company of its
assumption of the defense shall be at Indemnitee’s own expense; provided, that if (i) Indemnitee’s employment of its own legal counsel has been authorized by the Company, (ii) Indemnitee has reasonably determined that
there may be a conflict of interest between Indemnitee and the Company in the defense of such Claim, (iii) after a Change in Control, Indemnitee’s employment of its own counsel has been approved by the Independent Counsel, or (iv) the
Company shall not in fact have employed counsel to assume the defense of such Claim, then Indemnitee shall be entitled to retain its own separate counsel (but not more than one law firm plus, if applicable, local counsel in respect of any such
Claim) and all Expenses related to such separate counsel shall be borne by the Company. 

Section 12.    Procedure Upon Application for Indemnification. 

(a)    Upon written request by Indemnitee for indemnification pursuant to Section 11(a), a determination, if required
by applicable law, with respect to Indemnitee’s entitlement thereto shall be made in the specific case: (i) if a Change in Control shall have 

  
 -8- 








 
occurred, by Independent Counsel in a written opinion to the Board, a copy of which shall be delivered to Indemnitee; or (ii) if a Change in Control shall not have occurred, (A) by a
majority vote of the Disinterested Directors, even though less than a quorum of the Board, (B) by a committee of Disinterested Directors designated by a majority vote of the Disinterested Directors, even though less than a quorum of the Board,
(C) if there are no such Disinterested Directors or, if such Disinterested Directors so direct, by Independent Counsel in a written opinion to the Board, a copy of which shall be delivered to Indemnitee, or (D) if so directed by the Board,
by the stockholders of the Company; and, if it is so determined that Indemnitee is entitled to indemnification, payment to Indemnitee shall be made within ten (10) days after such determination. Indemnitee shall cooperate with the person,
persons or entity making such determination with respect to Indemnitee’s entitlement to indemnification, including providing to such person, persons or entity upon reasonable advance request any documentation or information which is not
privileged or otherwise protected from disclosure and which is reasonably available to Indemnitee and reasonably necessary to such determination. Any costs or Expenses (including attorneys’ fees and disbursements) incurred by Indemnitee in so
cooperating with the person, persons or entity making such determination shall be borne by the Company (irrespective of the determination as to Indemnitee’s entitlement to indemnification) and the Company hereby indemnifies and agrees to hold
Indemnitee harmless therefrom. The Company promptly will advise Indemnitee in writing with respect to any determination that Indemnitee is or is not entitled to indemnification, including a description of any reason or basis for which
indemnification has been denied. 
 (b)    In the event the determination of entitlement to indemnification is to be
made by Independent Counsel pursuant to Section 12(a) hereof, the Independent Counsel shall be selected as provided in this Section 12(b). If a Change in Control shall not have occurred, the Independent Counsel shall be selected by the
Board, and the Company shall give written notice to Indemnitee advising Indemnitee of the identity of the Independent Counsel so selected. If a Change in Control shall have occurred, the Independent Counsel shall be selected by Indemnitee (unless
Indemnitee shall request that such selection be made by the Board, in which event the preceding sentence shall apply), and Indemnitee shall give written notice to the Company advising it of the identity of the Independent Counsel so selected. In
either event, Indemnitee or the Company, as the case may be, may, within ten (10) days after such written notice of selection shall have been given, deliver to the Company or to Indemnitee, as the case may be, a written objection to such
selection; provided, however, that such objection may be asserted only on the ground that the Independent Counsel so selected does not meet the requirements of “Independent Counsel” as defined in Section 2 of this
Agreement, and the objection shall set forth with particularity the factual basis of such assertion. Absent a proper and timely objection, the person so selected shall act as Independent Counsel. If such written objection is so made and
substantiated, the Independent Counsel so selected may not serve as Independent Counsel unless and until such objection is withdrawn or the Delaware Court has determined that such objection is without merit. If, within twenty (20) days after
the later of submission by Indemnitee of a written request for indemnification pursuant to Section 11(a) hereof and the final disposition of the Proceeding, no Independent Counsel shall have been selected and not objected to, either the Company
or Indemnitee may petition the Delaware Court for resolution of any objection which shall have been made by the Company or Indemnitee to the other’s selection of Independent Counsel and/or for the appointment as Independent Counsel of a person
selected by such court or 

  
 -9- 








 
by such other person as such court shall designate, and the person with respect to whom all objections are so resolved or the person so appointed shall act as Independent Counsel under
Section 12(a) hereof. Upon the due commencement of any judicial proceeding or arbitration pursuant to Section 14(a) of this Agreement, Independent Counsel shall be discharged and relieved of any further responsibility in such capacity
(subject to the applicable standards of professional conduct then prevailing). 
 Section 13.    Presumptions
and Effect of Certain Proceedings. 
 (a)    In making a determination with respect to entitlement to indemnification
hereunder, the person or persons or entity making such determination shall, to the fullest extent not prohibited by law, presume that Indemnitee is entitled to indemnification under this Agreement if Indemnitee has submitted a request for
indemnification in accordance with Section 11(a) of this Agreement, and the Company shall, to the fullest extent not prohibited by law, have the burden of proof to overcome that presumption in connection with the making by any person, persons
or entity of any determination contrary to that presumption. Neither the failure of the Company (including by its directors or Independent Counsel) to have made a determination prior to the commencement of any action pursuant to this Agreement that
indemnification is proper in the circumstances because Indemnitee has met the applicable standard of conduct, nor an actual determination by the Company (including by its directors or Independent Counsel) that Indemnitee has not met such applicable
standard of conduct, shall be a defense to the action or create a presumption that Indemnitee has not met the applicable standard of conduct. 

(b)    The termination of any Proceeding or of any claim, issue or matter therein, by judgment, order, settlement or
conviction, or upon a plea of nolo contendere or its equivalent, shall not (except as otherwise expressly provided in this Agreement) of itself adversely affect the right of Indemnitee to indemnification or create a presumption that
Indemnitee did not act in good faith and in a manner which Indemnitee reasonably believed to be in or not opposed to the best interests of the Company or, with respect to any criminal Proceeding, that Indemnitee had reasonable cause to believe that
Indemnitee’s conduct was unlawful. 
 (c)    For purposes of any determination of good faith, Indemnitee shall be
deemed to have acted in good faith if Indemnitee’s action is based on the records or books of account of the Enterprise, including financial statements, or on information supplied to Indemnitee by the directors or officers of the Enterprise in
the course of their duties, or on the advice of legal counsel for the Enterprise or on information or records given or reports made to the Enterprise by an independent certified public accountant or by an appraiser, financial advisor or other expert
selected with reasonable care by or on behalf of the Enterprise as to matters Indemnitee reasonably believes are within such Person’s professional or expert competence. The provisions of this Section 13(c) shall not be deemed to be
exclusive or to limit in any way the other circumstances in which the Indemnitee may be deemed to have met the applicable standard of conduct set forth in this Agreement. 

(d)    The knowledge and/or actions, or failure to act, of any director, officer, trustee, partner, managing member,
fiduciary, agent or employee of the Enterprise shall not be 

  
 -10- 








 
imputed to Indemnitee for purposes of determining the right to indemnification under this Agreement. 

Section 14.    Remedies of Indemnitee. 

(a)    Subject to Section 14(e), in the event that (i) a determination is made pursuant to Section 12 that
Indemnitee is not entitled to indemnification under this Agreement, (ii) advancement of Expenses is not timely made pursuant to Section 10, (iii) no determination of entitlement to indemnification shall have been made pursuant to
Section 12(a) within ninety (90) days after receipt by the Company of the request for indemnification, (iv) payment of indemnification is not made pursuant to Section 5, 6 or 7 or the second to last sentence of Section 12(a)
within ten (10) days after receipt by the Company of a written request therefor, (v) payment of indemnification pursuant to Section 3, 4 or 8 is not made within ten (10) days after a determination has been made that Indemnitee is
entitled to indemnification or (vi) in the event that the Company or any other person takes or threatens to take any action to declare this Agreement void or unenforceable, or institutes any litigation or other action or Proceeding designed to
deny, or to recover from, the Indemnitee the benefits provided or intended to be provided to the Indemnitee hereunder, Indemnitee shall be entitled to an adjudication by the Delaware Court of Indemnitee’s entitlement to such indemnification or
advancement of Expenses. Alternatively, Indemnitee, at Indemnitee’s option, may seek an award in arbitration to be conducted by a single arbitrator pursuant to the Commercial Arbitration Rules of the American Arbitration Association. Indemnitee
shall commence such proceeding seeking an adjudication or an award in arbitration within 180 days following the date on which Indemnitee first has the right to commence such proceeding pursuant to this Section 14(a). The Company shall not
oppose Indemnitee’s right to seek any such adjudication or award in arbitration. 
 (b)    In the event that a
determination shall have been made pursuant to Section 12(a) that Indemnitee is not entitled to indemnification, any judicial proceeding or arbitration commenced pursuant to this Section 14 shall be conducted in all respects as a de
novo trial, or arbitration, on the merits and Indemnitee shall not be prejudiced by reason of that adverse determination. In any judicial proceeding or arbitration commenced pursuant to this Section 14 the Company shall have the burden
of proving Indemnitee is not entitled to indemnification or advancement of Expenses, as the case may be. 
 (c)    If a
determination shall have been made pursuant to Section 12(a) that Indemnitee is entitled to indemnification, the Company shall be bound by such determination in any judicial proceeding or arbitration commenced pursuant to this Section 14,
absent (i) a misstatement by Indemnitee of a material fact, or an omission of a material fact necessary to make Indemnitee’s statement not materially misleading, in connection with the request for indemnification, or (ii) a
prohibition of such indemnification under applicable law. 
 (d)    The Company shall, to the fullest extent not
prohibited by law, be precluded from asserting in any judicial proceeding or arbitration commenced pursuant to this Section 14 that the procedures and presumptions of this Agreement are not valid, binding and enforceable and shall stipulate in
any such court or before any such arbitrator that the Company is bound by all the provisions of this Agreement. It is the intent of the Company that, to the 

  
 -11- 








 
fullest extent permitted by law, the Indemnitee not be required to incur legal fees or other Expenses associated with the interpretation, enforcement or defense of Indemnitee’s rights under
this Agreement by litigation or otherwise because the cost and expense thereof would substantially detract from the benefits intended to be extended to the Indemnitee hereunder. The Company shall, to the fullest extent permitted by law, indemnify
Indemnitee against any and all Expenses and, if requested by Indemnitee, shall (within ten (10) days after receipt by the Company of a written request therefor) advance, to the extent not prohibited by law, such Expenses to Indemnitee, which
are incurred by Indemnitee in connection with any action brought by Indemnitee for indemnification or advancement of Expenses from the Company under this Agreement or under any directors’ and officers’ liability insurance policies
maintained by the Company if, in the case of indemnification, Indemnitee is wholly successful on the underlying claims; if Indemnitee is not wholly successful on the underlying claims, then such indemnification shall be only to the extent Indemnitee
is successful on such underlying claims or otherwise as permitted by law, whichever is greater. 

(e)    Notwithstanding anything in this Agreement to the contrary, no determination as to entitlement of Indemnitee to
indemnification under this Agreement shall be required to be made prior to the final disposition of the Proceeding. 

Section 15.    Non-exclusivity; Survival of Rights; Insurance;
Subrogation. 
 (a)    The rights of indemnification and to receive advancement of Expenses as provided by this
Agreement shall not be deemed exclusive of any other rights to which Indemnitee may at any time be entitled under applicable law, the Certificate of Incorporation, the Bylaws, any agreement, a vote of stockholders or a resolution of directors, or
otherwise. No amendment, alteration or repeal of this Agreement or of any provision hereof shall limit or restrict any right of Indemnitee under this Agreement in respect of any action taken or omitted by Indemnitee in Indemnitee’s Corporate
Status prior to such amendment, alteration or repeal. To the extent that a change in Delaware law, whether by statute or judicial decision, permits greater indemnification or advancement of Expenses than would be afforded currently under the
Certificate of Incorporation, the Bylaws and this Agreement, it is the intent of the parties hereto that Indemnitee shall enjoy by this Agreement the greater benefits so afforded by such change. No right or remedy herein conferred is intended to be
exclusive of any other right or remedy, and every other right and remedy shall be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment
of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other right or remedy. 

(b)    To the extent that the Company maintains an insurance policy or policies providing liability insurance for
directors, officers, employees, or agents of the Enterprise, Indemnitee shall be covered by such policy or policies in accordance with its or their terms to the maximum extent of the coverage available for any such director, officer, employee or
agent under such policy or policies. If, at the time of the receipt of a notice of a claim pursuant to the terms hereof, the Company has director and officer liability insurance in effect, the Company shall give prompt notice of such claim or of the
commencement of a Proceeding, as the case may be, to the insurers in accordance with the procedures set forth in the respective policies. The 

  
 -12- 








 
Company shall thereafter take all necessary or desirable action to cause such insurers to pay, on behalf of the Indemnitee, all amounts payable as a result of such Proceeding in accordance with
the terms of such policies. 
 (c)    In the event of any payment made by the Company under this Agreement, the Company
shall be subrogated to the extent of such payment to all of the rights of recovery of Indemnitee, who shall execute all papers required and take all action necessary to secure such rights, including execution of such documents as are necessary to
enable the Company to bring suit to enforce such rights. 
 (d)    The Company shall not be liable under this Agreement
to make any payment of amounts otherwise indemnifiable (or for which advancement is provided hereunder) hereunder if and to the extent that Indemnitee has otherwise actually received such payment under any insurance policy, contract, agreement or
otherwise. 
 (e)    The Company’s obligation to indemnify or advance Expenses hereunder to Indemnitee who is or
was serving at the request of the Company as a director, officer, trustee, partner, managing member, fiduciary, employee or agent of any other corporation, limited liability company, partnership, joint venture, trust, employee benefit plan or other
enterprise shall be reduced by any amount Indemnitee has actually received as indemnification or advancement of Expenses from such other corporation, limited liability company, partnership, joint venture, trust or other enterprise. 

Section 16.    Duration of Agreement; Successors and Assigns. This Agreement shall continue until and
terminate upon the later of: (a) ten (10) years after the date that Indemnitee shall have ceased to serve as a director or officer of the Company or (b) one (1) year after the final termination of any Proceeding then pending in respect of
which Indemnitee is granted rights of indemnification or advancement of Expenses hereunder and of any proceeding commenced by Indemnitee pursuant to Section 14 of this Agreement relating thereto. The indemnification and advancement of expenses
rights provided by or granted pursuant to this Agreement shall be binding upon and be enforceable by the parties hereto and their respective successors and assigns (including any direct or indirect successor by purchase, merger, consolidation or
otherwise to all or substantially all of the business or assets of the Company), shall continue as to an Indemnitee who has ceased to be a director, officer, employee or agent of the Company or of any other Enterprise, and shall inure to the benefit
of Indemnitee and Indemnitee’s spouse, assigns, heirs, devisees, executors and administrators and other legal representatives. 

Section 17.    Severability. If any provision or provisions of this Agreement shall be held to be invalid,
illegal or unenforceable for any reason whatsoever: (a) the validity, legality and enforceability of the remaining provisions of this Agreement (including without limitation, each portion of any Section of this Agreement containing any such
provision held to be invalid, illegal or unenforceable, that is not itself invalid, illegal or unenforceable) shall not in any way be affected or impaired thereby and shall remain enforceable to the fullest extent permitted by law; (b) such
provision or provisions shall be deemed reformed to the extent necessary to conform to applicable law and to give the maximum effect to the intent of the parties hereto; and (c) to the fullest extent possible, the provisions of this Agreement
(including, without limitation, 

  
 -13- 








 
each portion of any Section of this Agreement containing any such provision held to be invalid, illegal or unenforceable, that is not itself invalid, illegal or unenforceable) shall be construed
so as to give effect to the intent manifested thereby. 
 Section 18.    Enforcement. 

(a)    The Company expressly confirms and agrees that it has entered into this Agreement and assumed the obligations
imposed on it hereby in order to induce Indemnitee to serve as a director or officer of the Company, and the Company acknowledges that Indemnitee is relying upon this Agreement in serving or continuing to serve as a director or officer of the
Company. 
 (b)    This Agreement constitutes the entire agreement between the parties hereto with respect to the
subject matter hereof and supersedes all prior agreements and understandings, oral, written and implied, between the parties hereto with respect to the subject matter hereof; provided, however, that this Agreement is a supplement to and in
furtherance of the Certificate of Incorporation, the Bylaws and applicable law, and shall not be deemed a substitute therefor, nor to diminish or abrogate any rights of Indemnitee thereunder. 

Section 19.    Modification and Waiver. No supplement, modification or amendment of this Agreement shall be
binding unless executed in writing by the parties hereto. No waiver of any of the provisions of this Agreement shall be deemed or shall constitute a waiver of any other provisions of this Agreement nor shall any waiver constitute a continuing
waiver. 
 Section 20.    Notices. All notices, requests, demands and other communications under this
Agreement shall be in writing and shall be deemed to have been duly given if (a) delivered by hand and receipted for by the party to whom said notice or other communication shall have been directed, (b) mailed by certified or registered
mail with postage prepaid, on the third business day after the date on which it is so mailed, (c) mailed by reputable overnight courier and receipted for by the party to whom said notice or other communication shall have been directed or
(d) sent by facsimile transmission, with receipt of oral confirmation that such transmission has been received: 

(a)    If to Indemnitee, at the address indicated on the signature page of this Agreement, or such other address as
Indemnitee shall provide to the Company. 
 (b)    If to the Company to 

Alcoa Corporation

 Pittsburgh, PA 15212 

Attn: General Counsel 
 or to any other address
as may have been furnished to Indemnitee by the Company. 
 Section 21.    Contribution. To the fullest
extent permissible under applicable law, if the indemnification provided for in this Agreement is unavailable to Indemnitee for any reason 

  
 -14- 








 
whatsoever, the Company, in lieu of indemnifying Indemnitee, shall contribute to the amount incurred by Indemnitee, whether for judgments, fines, penalties, excise taxes, amounts paid or to be
paid in settlement and/or for Expenses, in connection with any claim relating to an indemnifiable event under this Agreement, in such proportion as is deemed fair and reasonable in light of all of the circumstances of such Proceeding in order to
reflect (i) the relative benefits received by the Company and Indemnitee as a result of the event(s) and/or transaction(s) giving cause to such Proceeding; and/or (ii) the relative fault of the Company (and its directors, officers,
employees and agents) and Indemnitee in connection with such event(s) and/or transaction(s). 

Section 22.    Applicable Law and Consent to Jurisdiction. This Agreement and the legal relations among the
parties shall be governed by, and construed and enforced in accordance with, the laws of the State of Delaware, without regard to its conflict of laws rules. Except with respect to any arbitration commenced by Indemnitee pursuant to
Section 14(a) of this Agreement, the Company and Indemnitee hereby irrevocably and unconditionally (i) agree that any action or proceeding arising out of or in connection with this Agreement shall be brought only in the Court of Chancery
of the State of Delaware (the “Delaware Court”), and not in any other state or federal court in the United States of America or any court in any other country, (ii) consent to submit to the exclusive jurisdiction of the Delaware Court
for purposes of any action or proceeding arising out of or in connection with this Agreement, (iii) appoint, to the extent such party is not otherwise subject to service of process in the State of Delaware, irrevocably The Corporation Trust
Company, Corporation Trust Center, 1209 Orange Street, Wilmington, New Castle County, Delaware 19801 as its agent in the State of Delaware as such party’s agent for acceptance of legal process in connection with any such action or proceeding
against such party with the same legal force and validity as if served upon such party personally within the State of Delaware, (iv) waive any objection to the laying of venue of any such action or proceeding in the Delaware Court and
(v) waive, and agree not to plead or to make, any claim that any such action or proceeding brought in the Delaware Court has been brought in an improper or inconvenient forum. 

Section 23.    Counterparts. This Agreement may be executed in one or more counterparts, each of which shall
for all purposes be deemed to be an original but all of which together shall constitute one and the same Agreement. Only one such counterpart signed by the party against whom enforceability is sought needs to be produced to evidence the existence of
this Agreement. 
 Section 24.    Miscellaneous. Use of the masculine pronoun shall be deemed to include
usage of the feminine pronoun where appropriate. The headings of this Agreement are inserted for convenience only and shall not be deemed to constitute part of this Agreement or to affect the construction thereof. This Agreement is a supplement to
and in furtherance of the Certificate of Incorporation and the Bylaws and any resolutions adopted pursuant thereto, and shall not be deemed a substitute therefor, nor to diminish or abrogate any rights of Indemnitee thereunder.
