below and the provisions of Section 4(b), up to 11,500,000 Shares may be issued under the Plan, which reflects an increase of 3,000,000 Shares, effective as of the 2021 Amendment Date, from 8,500,000, the number of Shares that were authorized
for issuance under the Plan as of the Effective Date. As from the 2021 Amendment Date, each Share issued pursuant to the exercise or settlement of an Award under the Plan shall be counted against the number of Shares reserved under this
Section 4(a) as one Share for every one Share issued. Each Share issued pursuant to the exercise of an Option or Stock Appreciation Right prior to the 2021 Amendment Date was counted against the number of Shares reserved under this
Section 4(a) as one Share for each Option or Stock Appreciation Right and each Share issued pursuant to the settlement of an Award other than an Option or a Stock Appreciation Right prior to the 2021 Amendment Date was counted against the
number of Shares reserved under this Section 4(a) as 1.5 Shares for every one Share. Any Shares issued pursuant to a Converted Award shall reduce the maximum number of Shares issuable under this Section 4(a) in accordance with the
provisions of Section 4(a). 

  

	(b)	 Share Replenishment. In addition to the Shares authorized by Section 4(a), Shares underlying Awards
(including Converted Awards) that are granted under the Plan, which are subsequently forfeited, cancelled or expire in accordance with the terms of the Award shall become available for issuance under the Plan. As from the 2021 Amendment Date, any
Shares that again become available for issuance pursuant to this Section 4(b) shall be added back to the number of Shares reserved under Section 4(a) as one Share for each Share subject to the forfeited, cancelled or expired Award
(including any Converted Award). The following Shares shall not become available for issuance under the Plan: (x) Shares tendered in payment of an Option or other Award, and (y) Shares withheld for taxes. Shares purchased by the Company
using Option proceeds shall not become available for issuance under the Plan, and if Stock Appreciation Rights are settled in Shares, each Stock Appreciation Right shall count as one Share whether or not Shares are actually issued or transferred
under the Plan. 

  

	(c)	 Issued Shares. Shares shall be deemed to be issued hereunder only when and to the extent that payment or
settlement of an Award is actually made in Shares. Notwithstanding anything herein to the contrary, the Committee may at any time authorize a cash payment in lieu of Shares, including without limitation if there are insufficient Shares available for
issuance under the Plan to satisfy an obligation created under the Plan. 

  

	(d)	 Source of Shares. Any Shares issued hereunder may consist, in whole or in part, of authorized and
unissued Shares, treasury Shares or Shares purchased in the open market or otherwise.

Shares available for issuance under the Plan or to a Participant in any calendar year. 

  

	(f)	 Adjustments. Subject to SECTION 12: 

 

	 	(i)	 Corporate Transactions other than an Equity Restructuring. In the event of any stock dividend, stock
split, combination or exchange of shares, merger, consolidation or other distribution (other than normal cash dividends) of Company assets to shareholders, or any other change affecting the Shares or the price of the Shares other than an Equity
Restructuring, the Committee shall make such adjustments, if any, as the Committee in its discretion may deem appropriate to reflect such change with respect to (i) the aggregate number and kind of shares that may be issued under the Plan
(including, but not limited to, adjustments of the limitations in Sections 4(a) and 13(d) hereof); (ii) the terms and conditions of any outstanding Awards (including, without limitation, any applicable performance targets or criteria with respect
thereto); and (iii) the grant or exercise price per Share for any outstanding Awards under the Plan.

 In the event of any transaction or event described above in this Section 4(f)(i) or
any unusual or nonrecurring transactions or events affecting the Company, any affiliate of the Company, or the financial statements of the Company or any affiliate, or of changes in applicable laws, regulations or accounting principles, the
Committee, on such terms and conditions as it deems appropriate, either by the terms of the Award or by action taken prior to the occurrence of such transaction or event (except that action to give effect to a change in applicable laws or accounting
principles may be made within a reasonable period of time after such change), is hereby authorized to take actions, including but not limited to any one or more of the following actions, whenever the Committee determines that such action is
appropriate in order to prevent dilution or enlargement of the benefits or potential benefits intended to be made available under the Plan or with respect to any Award under the Plan, to facilitate such transactions or events or to give effect to
such changes in laws, regulations or principles, provided that the number of Shares subject to any Award will always be a whole number: 
  

	 	(A)	 To provide for either (I) termination of any such Award in exchange for an amount of cash, if any, equal
to the amount that would have been attained upon the exercise of such Award or realization of the Participant’s rights (and, for the avoidance of doubt, if as of the date of the occurrence of the transaction or event described above in this
Section 4(f)(i) the Committee determines in good faith that no amount would have been attained upon the exercise of such Award or realization of the Participant’s rights, then such Award may be terminated by the Company without payment) or
(II) the replacement of such Award with other rights or property selected by the Committee in its sole discretion; 

  

	 	(B)	 To provide that such Award be assumed by the successor or survivor corporation, or a parent or subsidiary
thereof, or shall be substituted for by similar options, rights or awards covering the stock of the successor or survivor corporation, or a parent or subsidiary thereof, with appropriate adjustments as to the number and kind of shares and prices;

  

	 	(C)	 To make adjustments in the number and type of Shares (or other securities or property) subject to outstanding
Awards, and in the number and kind of outstanding Restricted Shares and/or in the terms and conditions of (including the grant or exercise price), and the criteria included in, outstanding options, rights and awards; 

 

	 	(D)	 To provide that such Award shall be exercisable or payable or fully vested with respect to all Shares covered
thereby; or 

  

	 	(E)	 To provide that the Award cannot vest, be exercised or become payable after such event.

 

	 	(ii)	 Equity Restructuring. In connection with the occurrence of any Equity Restructuring, and notwithstanding
anything to the contrary in this Section 4(f), the Committee will adjust the terms of the Plan and each outstanding Award as it deems equitable to reflect the Equity Restructuring, which may include (i) adjusting the number and type of
securities subject to each outstanding Award and/or with respect to which Awards may be granted under the Plan (including, but not limited to, adjustments of the limitations in Sections 4(a) and 13(d) hereof); (ii) adjusting the terms and conditions
of (including the grant or exercise price), and the performance targets or other criteria included in, outstanding Awards; and (iii) granting new Awards or making cash payments to Participants. The adjustments provided under this
Section 4(f)(ii) will be nondiscretionary and final and binding on all interested parties, including the affected Participant and the Company; provided that the Committee will determine whether an adjustment is equitable and the number of
Shares subject to any Award will always be a whole number.

 SECTION 5. ELIGIBILITY AND VESTING REQUIREMENTS. 

 

	(a)	 Eligibility. Any Director or Employee shall be eligible to be selected as a
Participant.

  

	(b)	 Minimum Vesting. Notwithstanding any other provision of the Plan to the contrary, all Awards granted
under the Plan shall have a minimum vesting period of one year measured from the date of grant; provided, however, that up to 5% of the Shares available for distribution under the Plan may be granted without such minimum vesting

	 	
requirement. Nothing in this Section 5(b) shall limit the Company’s ability to grant Awards that contain rights to accelerated vesting on a termination of employment or service (or to
otherwise accelerate vesting), or limit any rights to accelerated vesting in connection with a Change in Control, as provided in SECTION 12 of the Plan. In addition, the minimum vesting requirement set forth in this Section 5(b) shall not apply
to Converted Awards or Substitute Awards or to Director Awards which vest on the earlier of the one-year anniversary of the date of grant and the next annual meeting of the Company’s shareholders (which
is at least 50 weeks after the immediately preceding year’s annual meeting) and shall not limit the adjustment provisions of Section 4(f).

SECTION 6. STOCK OPTIONS. Options may be granted hereunder to Participants either alone or in addition to other Awards granted under the Plan. Any
Option granted under the Plan may be evidenced by an Award Agreement in such form as the Committee from time to time approves. Any such Option shall be subject to the terms and conditions required by this SECTION 6 and to such additional terms and
conditions, not inconsistent with the provisions of the Plan, as the Committee may deem appropriate in each case. 
  

	(a)	 Option Price. The purchase price (or Option price) per Share purchasable under an Option shall be
determined by the Committee in its sole discretion; provided that, except in connection with an adjustment provided for in Section 4(f) or with respect to Converted Awards or Substitute Awards, such purchase price shall not be less than the
Fair Market Value of one Share on the date of the grant of the Option. The Committee may, in its sole discretion, establish a limit on the amount of gain that can be realized on an Option.

permitted by law and the Committee, Awards) having a fair market value on the exercise date equal to the total Option price, or by any combination of cash, Shares and other consideration as the Committee may specify in the applicable Award
Agreement. 

 SECTION 7. STOCK APPRECIATION RIGHTS. Stock Appreciation Rights may be granted to Participants on such terms and
conditions as the Committee may determine, subject to the requirements of the Plan. A Stock Appreciation Right shall confer on the holder a right to receive, upon exercise, the excess of (i) the Fair Market Value of one Share on the date of
exercise or, if the Committee shall so determine, at any time during a specified period before the date of exercise over (ii) the grant price of the right on the date of grant, or if granted in connection with an outstanding Option on the date
of grant of the related Option, as specified by the Committee in its sole discretion, which, except in the case of Converted Awards or Substitute Awards or in connection with an adjustment provided in Section 4(f), shall not be less than the
Fair Market Value of one Share on such date of grant of the right or the related Option, as the case may be. Any payment by the Company in respect of such right may be made in cash, Shares, other property or any combination thereof, as the
Committee, in its sole discretion, shall determine. The Committee may, in its sole discretion, establish a limit on the amount of gain that can be realized on a Stock Appreciation Right.

provided, however, and except as provided in Section 4(f) or with respect to Converted Awards or Substitute Awards, that such price shall not be less than 100% of the Fair Market Value of one Share on the date of grant of the Stock Appreciation

the Plan to the contrary, unless the Committee shall determine otherwise at the time of grant with respect to a particular Award, in the event of a Change in Control: 

 

	 	(i)	 any Time-Based Award consisting of Options, Stock Appreciation Rights or any other Time-Based Award in the form
of rights that are exercisable by Participants upon vesting (“Exercisable Time-Based Award”), that is outstanding as of the date on which a Change in Control shall be deemed to have occurred and that is not then vested, shall
become vested and exercisable, unless replaced by a Replacement Award; 

  

	 	(ii)	 any Time-Based Award that is not an Exercisable Time-Based Award that is outstanding as of the date on which a
Change in Control shall be deemed to have occurred and that is not then vested, shall become free of all contingencies, restrictions and limitations and shall become vested and transferable, unless replaced by a Replacement Award;

  

	 	(iii)	 any Replacement Award for which an Exercisable Time-Based Award has been exchanged upon a Change in Control
shall vest and become exercisable in accordance with the vesting schedule and term for exercisability that applied to the corresponding Exercisable Time-Based Award immediately prior to such Change in Control, provided, however, that
if within twenty four (24) months of such Change in Control, the Participant’s service with the Company or a Subsidiary is terminated without Cause (as such term is defined in the Arconic Corporation Change in Control Severance Plan) or by
the Participant for Good Reason (as such term is defined in the Arconic Corporation Change in Control Severance Plan), such Award shall become vested and exercisable to the extent outstanding at the time of such termination of service. Any
Replacement Award that has become vested and exercisable pursuant to this paragraph shall expire on the earlier of (A) thirty six (36) months following the date of termination of such Participant’s service (or, if later, the
conclusion of the applicable post-termination exercise period pursuant to the applicable Award Agreement) and (B) the last day of the term of such Replacement Award; 

 

	 	(iv)	 any Replacement Award for which a Time-Based Award that is not an Exercisable Time-Based Award has been
exchanged upon a Change in Control shall vest in accordance with the vesting schedule that applied to the corresponding Time-Based Award immediately prior to such Change in Control, provided, however, that if within twenty four
(24) months of such Change in Control, the Participant’s service with the Company or a Subsidiary is terminated without Cause (as such term is defined in the Arconic Corporation Change in Control Severance Plan) or by the Participant for
Good Reason (as such term is defined in the Arconic Corporation Change in Control Severance Plan), such Award shall become free of all contingencies, restrictions and limitations and become vested and transferable to the extent outstanding;

  

	 	(v)	 any Performance Award shall be converted so that such Award is no longer subject to any performance condition
referred to in SECTION 11 above, but instead is subject to the passage of time, with the number or value of such Replacement Award determined as follows: (A) if 50% or more of the Performance Period has been completed as of the date on which
such Change in Control is deemed to have occurred, 

	 	
the number or value of such Award shall be based on actual performance during the Performance Period; or (B) if less than 50% of the Performance Period has been completed as of the date on
which such Change in Control is deemed to have occurred, the number or value of such Award shall be the target number or value. Paragraphs (i) through (iv) above shall govern the terms of such Time-Based Award. 

 

	(b)	 Change in Control Settlement. Notwithstanding any other provision of this Plan, if approved by the
Committee, upon a Change in Control, a Participant may receive a cash settlement under clauses (i) and (ii) below of existing Awards that are vested and exercisable as of the date on which such Change in Control shall be deemed to have
occurred: 

  

	 	(i)	 a Participant who holds an Option or Stock Appreciation Right may, in lieu of the payment of the purchase price
for the Shares being purchased under the Option or Stock Appreciation Right, surrender the Option or Stock Appreciation Right to the Company and receive cash, within 30 days of the Change in Control in an amount equal to the amount by which the Fair
Market Value of the Shares on the date of the Change in Control exceeds the purchase price per Share under the Option or Stock Appreciation Right multiplied by the number of Shares granted under the Option or Stock Appreciation Right; and

  

	 	(ii)	 a Participant who holds Restricted Share Units may, in lieu of receiving Shares which have vested under
Section 12(a)(ii) of this Plan, receive cash, within 30 days of a Change in Control (or at such other time as may be required to comply with Section 409A of the Code), in an amount equal to the Fair Market Value of the Shares on the date
of the Change in Control multiplied by the number of Restricted Share Units held by the Participant.

 SECTION 13. LIMITATIONS ON
PERFORMANCE AWARDS GRANTED TO PARTICIPANTS. 
  

	(a)	 Notwithstanding any other provision of this Plan, if the Committee grants a Performance Award to a Participant,
such Performance Award will be subject to the terms of this SECTION 13, unless otherwise expressly determined by the Committee. 

  

	(b)	 If an Award is subject to this SECTION 13 and is not an Option or a Stock Appreciation Right, then the lapsing
of contingencies or restrictions thereon and the distribution of cash, Shares or other property pursuant thereto, as applicable, shall be subject to the achievement by the Company on a consolidated basis, by specified Subsidiaries or divisions or
business units of the Company, and/or by the individual Participant, as appropriate, of one or more performance goals established by the Committee. Performance goals shall be based on such measures as selected by the Committee in its discretion,
including, without limitation, (i) GAAP or non-GAAP metrics, (ii) total shareholder return or other return-based metrics, (iii) operational, efficiency-based, strategic corporate or personal
professional objectives, (iv) sustainability or compliance targets or (v) any other metric that is capable of measurement as determined by the Committee. Performance goals may be calculated to exclude special items, unusual or infrequently
occurring items or nonrecurring items or may be normalized for fluctuations in market forces, including, but not limited to, foreign currency exchange rates and the price of aluminum on the London Metal Exchange. Performance goals shall be set by
the Committee (and any adjustments shall be made by the Committee, subject to Section 15(d)) within the first 25% of the Performance Period. 

  

	(c)	 Notwithstanding any provision of this Plan other than Section 4(f) and SECTION 12, with respect to any
Award that is subject to this SECTION 13 (other than an Option or a Stock Appreciation Right), the Committee may adjust downwards, but not upwards, the amount payable pursuant to such Award, and the Committee may not waive the achievement of the
applicable performance goals. 

  

	(d)	 Subject to the adjustment provisions of Section 4(f), with respect to Awards subject to this SECTION 13,
no Participant may be granted Options and/or Stock Appreciation Rights in any calendar year with respect to more than 2,500,000 Shares, or Restricted Share Awards or Restricted Share Unit Awards covering more than 750,000 Shares. The maximum dollar
value payable with respect to Performance Awards that are valued with reference to property other than Shares and granted to any Participant in any one calendar year is $15,000,000. The foregoing limits shall apply to any Awards made under this
SECTION 13, other than to Converted Awards which shall be disregarded for purposes of applying such limits.

 SECTION 14. AMENDMENTS AND TERMINATION. The Board or the Committee may amend, alter, suspend,
discontinue or terminate the Plan or any portion thereof at any time; provided that notwithstanding any other provision in this Plan, no such amendment, alteration, suspension, discontinuation or termination shall be made:
(a) without shareholder approval, if such approval would be required pursuant to applicable law or the requirements of the New York Stock Exchange or such other stock exchange on which the Shares trade; or (b) without the consent of the
affected Participant, if such action would materially impair the rights of such Participant under any outstanding Award, except as provided in Sections 15(e) and 15(f). Notwithstanding anything to the contrary herein but subject to
Section 14(a) hereof, the Board or the Committee may amend the Plan in such manner as may be necessary so as to have the Plan conform to local rules and regulations in any jurisdiction outside the United States or to qualify for or comply with
any tax or regulatory requirement for which or with which the Board or Committee deems it necessary or desirable to qualify or comply. 
 SECTION 15.
GENERAL PROVISIONS. 
  

	(a)	 Transferability of Awards. Awards may be transferred by will or the laws of descent and distribution.
Except as set forth herein, awards shall be exercisable, during the Participant’s lifetime, only by the Participant or, if permissible under applicable law, by the Participant’s guardian or legal representative. Unless otherwise provided
by the Committee or limited by applicable laws, a Participant may, in the manner established by the Committee, designate a beneficiary to exercise the rights of the Participant with respect to any Award upon the death of the Participant. Unless
otherwise provided by the Committee or limited by applicable laws, Awards may be transferred to one or more Family Members, individually or jointly, or to a trust whose beneficiaries include the Participant or one or more Family Members under terms
and conditions established by the Committee. The Committee shall have authority to determine, at the time of grant, any other rights or restrictions applicable to the transfer of Awards; provided however, that no Award may be transferred to a
third party for value or consideration. Except as provided in this Plan or the terms and conditions established for an Award, any Award shall be null and void and without effect upon any attempted assignment or transfer, including, without
limitation, any purported assignment, whether voluntary or by operation of law, pledge, hypothecation or other disposition, attachment, divorce or trustee process or similar process, whether legal or equitable. 

 

	(b)	 Award Entitlement. No Employee or Director shall have any claim to be granted any Award under the Plan
and there is no obligation for uniformity of treatment of Employees or Directors under the Plan. 

  

	(c)	 Terms and Conditions of Award. The prospective recipient of any Award under the Plan shall be deemed to
have become a Participant subject to all the applicable terms and conditions of the Award upon the grant of the Award to the prospective recipient, unless the prospective recipient notifies the Company within 30 days of the grant that the
prospective recipient does not accept the Award. This Section 15(c) is without prejudice to the Company’s right to require a Participant to affirmatively accept the terms and conditions of an Award. The terms and conditions of Awards need
not be the same with respect to each recipient and the Committee is under no obligation to provide Participants with uniform Award terms. 

  

	(d)	 Award Adjustments. The Committee shall be authorized to make adjustments in Performance Award criteria
or in the terms and conditions of other Awards in recognition of unusual or nonrecurring events affecting the Company or its financial statements or changes in applicable laws, regulations or accounting principles. The Committee may correct any
defect, supply any omission or reconcile any inconsistency in the Plan or any Award in the manner and to the extent it shall deem desirable to carry it into effect. 

 

	(e)	 Committee Right to Cancel. The Committee shall have full power and authority to determine whether, to
what extent and under what circumstances any Award shall be canceled or suspended at any time prior to a Change in Control: (i) if an Employee, without the consent of the Committee, while employed by the Company or a Subsidiary or after
termination of such employment, becomes associated with, employed by, renders services to or owns any interest (other than an interest of up to 5% in a publicly traded company or any other nonsubstantial interest, as determined by the Committee) in
any business that is in competition with the Company or any Subsidiary; (ii) in the event of the Participant’s willful engagement in conduct which is, or might reasonably be expected to be, injurious to the Company or any Affiliate,
monetarily or otherwise, including, but not limited to, its reputation or standing in its industry; (iii) in the event of a Participant’s misconduct described in Section 15(f); or (iv) in order to comply with applicable laws as
described in Section 15(h) below. For purposes of clause 

	 	
(ii), no act, or failure to act, on the Participant’s part shall be deemed “willful” unless done, or omitted to be done, by the Participant not in good faith and without reasonable
belief that the Participant’s act, or failure to act, was in the best interest of the Company or an Affiliate. 

  

	(f)	 Clawback. In accordance with the Company’s Compensation Recovery Policy, as it may be amended from
time to time (the “Policy”), in the event a Participant is determined to have engaged in misconduct, the Committee shall have full power and authority to determine whether, to what extent, and under what circumstances any
Awards granted to such Participant shall be forfeited or cancelled and Shares received pursuant to any such Awards (or the value thereof) may be recouped by the Company. Notwithstanding the foregoing or any other provision of the Plan to the
contrary, in the event that: (i) the amount of any Award was calculated based upon the achievement of certain financial results that were subsequently the subject of a restatement (other than a restatement required because of changes in
applicable financial reporting standards or under similar circumstances), (ii) the Participant engaged in intentional misconduct that caused or partially caused the need for the restatement, and (iii) the amount of the Award had the financial
results been properly reported would have been lower than the amount actually awarded, then, to the full extent permitted by applicable law, in all appropriate cases, (x) the Committee will effect the cancellation or recovery of the Award to
the extent of the excess of any amount the Participant received under the Award over what he or she should have received absent the restatement, and (y) the Participant will pay to the Company the amount of any profits realized by the
Participant from the sale of any Shares relating to the Award, in the case of each of clause (x) and (y) during the period commencing 36 months prior to the date of the restatement and ending on the last day of the last period to which the
restatement applies, as such amount may be determined by the Committee. Furthermore, all Awards (including Awards that have vested in accordance with the Award Agreement) shall be subject to the terms and conditions, if applicable, of any other
recoupment policy that may be adopted by the Company from time to time or any recoupment requirement imposed under applicable laws, rules, regulations or stock exchange listing standards, including, without limitation, recoupment requirements
imposed pursuant to Section 954 of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, Section 304 of the Sarbanes-Oxley Act of 2002, or any regulations promulgated thereunder, or recoupment requirements under the laws
of any other jurisdiction. 

  

	(g)	 Stock Certificate Legends. All certificates for Shares delivered under the Plan pursuant to any Award
shall be subject to such stock transfer orders and other restrictions as the Committee may deem advisable under the rules, regulations, and other requirements of the U.S. Securities and Exchange Commission, any stock exchange upon which the Shares
are then listed and any applicable Federal or state securities law, and the Committee may cause a legend or legends to be put on any such certificates to make appropriate reference to such restrictions. 

 

	(h)	 Compliance with Securities Laws and Other Requirements. No Award granted hereunder shall be construed as
an offer to sell securities of the Company, and no such offer shall be outstanding, unless and until the Company in its sole discretion has determined that any such offer, if made, would be in compliance with all applicable requirements of the U.S.
Federal securities laws and any other laws, rules, regulations, stock exchange listing or other requirements to which such offer, if made, would be subject. Without limiting the foregoing, the Company shall have no obligation to issue or deliver
Shares pursuant to Awards granted hereunder prior to: (i) obtaining any approvals from governmental agencies that the Company determines are necessary or advisable, and (ii) completion of any registration or other qualification with
respect to the Shares under any applicable law in the United States or in a jurisdiction outside of the United States or procurement of any ruling or determination of any governmental body that the Company determines to be necessary or advisable or
at a time when any such registration, qualification or determination is not current, has been suspended or otherwise has ceased to be effective. The inability or impracticability of the Company to obtain or maintain authority from any regulatory
body having jurisdiction, which authority is deemed by the Company’s counsel to be necessary to the lawful issuance and sale of any Shares hereunder, shall relieve the Company of any liability in respect of the failure to issue or sell such
Shares as to which such requisite authority shall not have been obtained, and shall constitute circumstances in which the Committee may determine to amend or cancel Awards pertaining to such Shares, with or without consideration to the affected
Participants. 

  

	(i)	 Dividends. No Award of Options or Stock Appreciation Rights shall have the right to receive dividends or
dividend equivalents. A recipient of an Award of Restricted Shares shall receive dividends on the Restricted Shares, subject to this Section 15(i) and such other contingencies or restrictions, if any, as the Committee, in its

	 	
sole discretion, may impose. Unless otherwise determined by the Committee, dividend equivalents shall accrue on Restricted Share Units (including Restricted Share Units that have a performance
feature) and shall only be paid if and when such Restricted Share Units vest. Dividend equivalents that accrue on Restricted Share Units will be calculated at the same rate as dividends paid on the common stock of the Company. Notwithstanding any
provision herein to the contrary, no dividends or dividend equivalents shall be paid on Restricted Share Units that have not vested or on Restricted Share Units that have not been earned during a Performance Period and in no event shall any other
Award provide for the Participant’s receipt of dividends or dividend equivalents in any form prior to the vesting of such Award or applicable portion thereof. 

 

	(j)	 Consideration for Awards. Except as otherwise required in any applicable Award Agreement or by the terms
of the Plan, recipients of Awards under the Plan shall not be required to make any payment or provide consideration other than the rendering of services. 

  

	(k)	 Delegation of Authority by Committee. The Committee may delegate to one or more Executive Officers or a
committee of Executive Officers the right to grant Awards to Employees who are not Executive Officers or Directors of the Company and to cancel or suspend Awards to Employees who are not Executive Officers or Directors of the Company. The Committee
may delegate other of its administrative powers under the Plan to the extent not prohibited by applicable laws. 

  

	(l)	 Tax Obligations. The Company shall be authorized to withhold from any Award granted or payment due under
the Plan the amount of Tax Obligations due in respect of an Award or payment hereunder and to take such other action as may be necessary in the opinion of the Company to satisfy all obligations for the payment of such Tax Obligations, including
without limitation requiring the Participant to pay cash, withholding otherwise deliverable cash or Shares having a fair market value equal to the amount required to be withheld, forcing the sale of Shares issued pursuant to an Award (or exercise or
vesting thereof) having a fair market value equal to the amount required to be withheld, or requiring the Participant to deliver to the Company already-owned Shares having a fair market value equal to the amount required to be withheld. For purposes
of the foregoing, “Tax Obligations” means tax, social insurance and social security liability obligations and requirements in connection with the Awards, including, without limitation, (i) all U.S. Federal, state, and
local income, employment and any other taxes (including the Participant’s U.S. Federal Insurance Contributions Act (FICA) obligation) that are required to be withheld by the Company (or a Subsidiary, as applicable), (ii) the Participant’s
and, to the extent required by the Company (or a Subsidiary, as applicable), the Company’s (or a Subsidiary’s) fringe benefit tax liability, if any, associated with the grant, vesting, or exercise of an Award or sale of Shares issued under
the Award, and (iii) any other taxes, social insurance, social security liabilities or premium for which the Participant has an obligation, or which the Participant has agreed to bear, with respect to such Award (or exercise thereof or issuance
of Shares or other consideration thereunder). Furthermore, the Committee shall be authorized to, but is not required to, establish procedures for election by Participants to satisfy such obligations for the payment of such taxes by delivery of or
transfer of Shares to the Company or by directing the Company to retain Shares otherwise deliverable in connection with the Award. All personal taxes applicable to any Award under the Plan are the sole liability of the Participant.

  

	(m)	 Other Compensatory Arrangements. Nothing contained in this Plan shall prevent the Board from adopting
other or additional compensation arrangements, subject to shareholder approval if such approval is required; and such arrangements may be either generally applicable or applicable only in specific cases. 

 

	(n)	 Governing Law. The Plan and all determinations made and actions taken thereunder, to the extent not
otherwise governed by the laws of the United States, shall be governed by the laws of the State of Delaware, United States of America, without reference to principles of conflict of laws, and construed accordingly. 

 

	(o)	 Severability. If any provision of this Plan is or becomes or is deemed invalid, illegal or unenforceable
in any jurisdiction, or would disqualify the Plan or any Award under any law deemed applicable by the Committee, such provision shall be construed or deemed amended to conform to applicable laws or if it cannot be construed or deemed amended
without, in the determination of the Committee, materially altering the intent of the Plan, it shall be stricken and the remainder of the Plan shall remain in full force and effect. 

	(p)	 Awards to Non-U.S. Employees. Awards may be granted to Employees
and Directors who are foreign nationals or residents or employed outside the United States, or both, on such terms and conditions different from those applicable to Awards to Employees and Directors who are not foreign nationals or residents or who
are employed in the United States as may, in the judgment of the Committee, be necessary or desirable in order to recognize differences in local law, regulations or tax policy. Without limiting the generality of the foregoing, the Committee or the
Board, as applicable, are specifically authorized to (i) adopt rules and procedures regarding the conversion of local currency, withholding procedures and handling of stock certificates which vary with local requirements and (ii) adopt sub-plans, Award Agreements and Plan and Award Agreement addenda as may be deemed desirable to accommodate foreign laws, regulations and practice. The Committee also may impose conditions on the exercise or vesting
of Awards in order to minimize the Company’s or a Subsidiary’s obligation with respect to tax equalization for Employees on assignments outside their home countries. Notwithstanding the discretion of the Committee under this section, the
Participant remains solely liable for any applicable personal taxes. 

  

	(q)	 Repricing Prohibited. Except as provided in Section 4(f), the terms of outstanding Options or Stock
Appreciation Rights may not be amended, and action may not otherwise be taken without shareholder approval, to: (i) reduce the exercise price of outstanding Options or Stock Appreciation Rights, (ii) cancel outstanding Options or Stock
Appreciation Rights in exchange for Options or Stock Appreciation Rights with an exercise price that is less than the exercise price of the original Options or Stock Appreciation Rights, or (iii) replace outstanding Options or Stock
Appreciation Rights in exchange for other Awards or cash at a time when the exercise price of such Options or Stock Appreciation Rights is higher than the Fair Market Value of a Share. Nothing in this Section 15(q) shall be construed to apply
to the issuance of Converted Awards. 

  

	(r)	 Deferral. The Committee may require or permit Participants to elect to defer the issuance of Shares or
the settlement of Awards in cash or other property to the extent that such deferral complies with Section 409A of the Code. The Committee may also authorize the payment or crediting of interest, dividends or dividend equivalents on any deferred
amounts. 

  

	(s)	 Compliance with Section 409A of the Code. Except to the extent specifically provided
otherwise by the Committee and notwithstanding any other provision of the Plan, Awards under the Plan are intended to satisfy the requirements of Section 409A of the Code so as to avoid the imposition of any additional taxes or penalties under
Section 409A of the Code. If the Committee determines that an Award, payment, distribution, transaction or any other action or arrangement contemplated by the provisions of the Plan would, if undertaken, cause a Participant to become subject to
any additional taxes or other penalties under Section 409A of the Code, then unless the Committee specifically provides otherwise, such Award, payment, distribution, transaction or other action or arrangement shall not be given effect to the
extent it causes such result and the related provisions of the Plan and/or Award Agreement will be deemed modified, or, if necessary, suspended in order to comply with the requirements of Section 409A of the Code to the extent determined
appropriate by the Committee, in each case without the consent of or notice to the Participant. No payment that constitutes deferred compensation under Section 409A of the Code that would otherwise be made under the Plan or an Award Agreement
upon a Participant’s termination of employment will be made or provided unless and until such termination is also a “separation from service,” as determined in accordance with Section 409A of the Code. Notwithstanding the
foregoing or anything elsewhere in the Plan or an Award Agreement to the contrary, if a Participant is a “specified employee” within the meaning of Section 409A of the Code at the time of termination of employment with respect to an
Award, then solely to the extent necessary to avoid the imposition of any additional tax under Section 409A of the Code, the commencement of any payments or benefits under the Award shall be delayed to the extent required by Code
Section 409A(a)(2)(B)(i). Further notwithstanding anything to the contrary in the Plan, to the extent required under Section 409A of the Code in order to make payment of an Award upon a Change in Control, the applicable transaction or
event described in SECTION 2 must qualify as a change in the ownership or effective control of the Company or as a change in the ownership of a substantial portion of the assets of the Company pursuant to Section 409A(a)(2)(A)(v) of the Code,
and if it does not, then unless otherwise specified in the applicable Award Agreement, payment of such Award will be made on the Award’s original payment schedule or, if earlier, upon the death of the Participant. Although the Company may
attempt to avoid adverse tax treatment under Section 409A of the Code, the Company makes no representation to that effect and expressly disavows any covenant to maintain favorable or avoid unfavorable tax treatment. The Company

	 	
shall be unconstrained in its corporate activities without regard to the potential negative tax impact on holders of Awards under the Plan. 

 

	(t)	 Effect of Headings. The Section headings and subheadings herein are for convenience of reference only,
are not to be considered a part hereof, and shall in no way modify or restrict any of the terms or provisions hereof.

 SECTION 16.
TERM OF PLAN. No Award shall be granted pursuant to the Plan after the 10th anniversary of the Effective Date, but any Award theretofore granted may extend beyond that date. The Plan was approved by Arconic Inc., as the sole shareholder of
the Company, prior to the separation of the Company from Arconic Inc. and became effective as of the date of such separation on April 1, 2020 (the “Effective Date”). The Plan was subsequently amended and restated by the
Board, effective as of the date of its approval by the shareholders of the Company at the Company’s annual meeting of shareholders in 2021 (the “2021 Amendment Date”), and was further amended and restated by the
Committee on and effective as of May 17, 2022.EX-10.5

 Exhibit 10.5 

ARCONIC CORPORATION 

2020 ARCONIC STOCK INCENTIVE PLAN 

RESTRICTED SHARE UNIT AWARD AGREEMENT 

Grant Date: _________, 20__ 

The terms and conditions of this Global Restricted Share Unit Award Agreement, including Appendices A and B attached hereto, (the “Award
Agreement”) are authorized by the Compensation and Benefits Committee of the Board. The Restricted Share Unit award is granted to the Participant under the Arconic Corporation 2020 Stock Incentive Plan, as amended from time to time (the
“Plan”). Terms that are defined in the Plan have the same meanings in the Award Agreement. 
 NOTE: To avoid cancellation of the
Restricted Share Unit award, the Participant must affirmatively accept the Award and the terms of this Award Agreement within 6 months of the grant date, as set forth in paragraph 30 of the Award Agreement. 

General Terms and Conditions 
 1.
The Restricted Share Units are subject to the provisions of the Plan and the provisions of the Award Agreement. If the Plan and the Award Agreement are inconsistent, the provisions of the Plan will govern. Interpretations of the Plan and the Award
Agreement by the Committee are binding on the Participant and the Company. A Restricted Share Unit is an undertaking by the Company to issue the number of Shares indicated in the Participant’s account at Fidelity NetBenefits website https://nb.fidelity.com/, subject to the fulfillment of certain conditions, except to the extent otherwise provided in the Plan or herein. 

Vesting and Payment 
 2. A
Restricted Share Unit vests _____________________________ will be paid to the Participant in Shares on the vesting date or within 90 days thereafter. 

3. Except as provided in paragraph 4, if a Participant’s employment with the Company (including its Subsidiaries) is terminated before the
Restricted Share Unit vests, the Award is forfeited and is automatically canceled. 
 4. The following are exceptions to the vesting rules:

  

	 	•	 	 Death or Disability: a Restricted Share Unit held by a Participant, who dies while an Employee or who
is permanently and totally disabled while an Employee, is not forfeited but vests and is paid on the original stated vesting date set forth in paragraph 2. 

A Participant is deemed to be permanently and totally disabled if the Participant is unable to engage in any substantial
gainful activity by reason of any medically determinable physical or mental impairment which can be expected to result in death or which has lasted or can be expected to last for a continuous period of not less than 12 months. A Participant shall
not be considered to be permanently and totally disabled unless the Participant furnishes proof of the existence thereof in such form and manner, and at such times, as the Company may require. In the event of a dispute, the determination whether a
Participant is permanently and totally disabled will be made by the Committee or its delegate. 

	 	•	 	 Change in Control: a Restricted Share Unit vests if a Replacement Award is not provided following
certain Change in Control events, as described in the Plan. If the Change in Control qualifies as a “change in control event” within the meaning of Treas. Reg. § 1.409A-3(i)(5), the vested
Restricted Share Unit will be paid to the Participant within 30 days following the Change in Control. If the Change in Control does not so qualify, the vested Restricted Share Unit will be paid to the Participant on the original stated vesting date
set forth in paragraph 2. 

  

	 	•	 	 Termination Following Change in Control: as further described in the Plan, if a Replacement Award is
provided following a Change in Control, but within 24 months of such Change in Control the Participant’s employment is terminated without Cause (as defined in the Company’s Change in Control Severance Plan) or by the Participant for Good
Reason (as defined in the Company’s Change in Control Severance Plan), the Replacement Award will vest and will be paid to the Participant on the original stated vested date set forth in paragraph 2. 

 

	 	•	 	 Retirement: a Restricted Share Unit is not forfeited if it is held by a Participant who retires at
least 6 months after the grant date under a Company or Subsidiary plan (or if there is no Company or Subsidiary plan, a government retirement plan) in which the Participant is eligible for an immediate payment of a retirement benefit. In such event,
the Restricted Share Unit vests and is paid in accordance with the original vesting schedule of the grant set forth in paragraph 2. Immediate commencement of a deferred vested pension benefit under a Company or Subsidiary retirement plan is not
considered a retirement for these purposes. 

  

	 	•	 	 Divestiture: if a Restricted Share Unit is held by a Participant who is to be terminated from
employment with the Company or a Subsidiary as a result of a divestiture of a business or a portion of a business of the Company and the Participant either becomes an employee of (or is leased or seconded to) the entity acquiring the business on the
date of the closing, or the Participant is not offered employment with the entity acquiring the business and is terminated by the Company or a Subsidiary within 90 days of the closing of the sale, then, at the discretion of the Chief Executive
Officer of the Company, the Restricted Share Unit will not be forfeited and will vest and be paid in accordance with the original vesting schedule set forth in paragraph 2. For purposes of this paragraph, employment by “the entity acquiring the
business” includes employment by a subsidiary or affiliate of the entity acquiring the business; and “divestiture of a business” means the sale of assets or stock resulting in the sale of a going concern. “Divestiture of a
business” does not include a plant shut down or other termination of a business. 

 5. A Participant will receive one
Share upon the vesting and settlement of a Restricted Share Unit. Prior to issuance of the Shares, the Participant has no voting rights or dividend rights. Dividend equivalents will accrue on the Restricted Share Units, unless the Committee
determines that no dividend equivalents may be accrued or paid. Dividend equivalents that accrue on Restricted Share Units will be equal to the common stock dividend per Share payable on the Company’s common stock multiplied by the number of
Shares covered by the Restricted Share Unit Award. Notwithstanding any provision herein to the contrary, no dividends or dividend equivalents will be paid on Restricted Share Units that have not vested. 

Taxes 
 6. All taxes required to be
withheld under applicable tax laws in connection with a Restricted Share Unit must be paid by the Participant at the appropriate time under applicable tax laws. The Company may satisfy applicable tax withholding obligations by any of the means set
forth in Section 15(l) of the Plan, but will generally withhold from the Shares to be issued upon settlement of the Restricted Share Unit that number of Shares with a fair market value on the vesting date equal to the taxes required to be
withheld at the minimum required rates or, to the extent permitted under applicable accounting principles, at up to the maximum individual tax rate for the applicable tax jurisdiction, which include, for Participants subject to taxation in the
United States, applicable income taxes, federal and state unemployment compensation taxes and FICA/FUTA taxes. Notwithstanding the foregoing, if the Participant is subject 

  
 2 

 
to the short-swing profit rules of Section 16(b) of the Securities Exchange Act of 1934, as amended, the Company will withhold Shares from the Shares to be issued upon settlement of the
Restricted Share Unit, as described herein, and will not use the other means set forth in the Plan unless approved by the Committee or in the event that withholding in Shares is problematic under applicable tax or securities law or has materially
adverse accounting consequences. Further, notwithstanding anything herein to the contrary, the Company may cause a portion of the Restricted Share Units to vest prior to the stated vesting date set forth in paragraph 2 in order to satisfy any Tax-Related Items that arise prior to the date of settlement of the Restricted Share Units; provided that to the extent necessary to avoid a prohibited distribution under Section 409A of the Code, the number of
Restricted Share Units so accelerated and settled shall be with respect to a number of Shares with a value that does not exceed the liability for such Tax-Related Items. 

Beneficiaries 
 7. If permitted by
the Company, Participants will be entitled to designate one or more beneficiaries to receive all Restricted Share Units at the time of death of the Participant. All beneficiary designations must be made on the Fidelity Stock Plan Services
Beneficiary Designation Form which is available on Fidelity NetBenefits® website https://nb.fidelity.com/. 

8. Beneficiary designations on the approved form will be effective at the time processed by Fidelity Investments. Any designation form
previously filed by a Participant will be automatically revoked and superseded by a later-filed form. 
 9. A Participant will be entitled
to designate any number of beneficiaries on the form, and the beneficiaries may be natural or corporate persons. 
 10. The failure of any
Participant to obtain any recommended signature on the form will not prohibit the Company from treating such designation as valid and effective. No beneficiary will acquire any beneficial or other interest in any Restricted Share Unit prior to the
death of the Participant who designated such beneficiary. 
 11. Unless the Participant indicates on the form that a named beneficiary is to
receive Restricted Share Units only upon the prior death of another named beneficiary, all beneficiaries designated on the form will be entitled to share equally in the Restricted Share Units. Unless otherwise indicated, all such beneficiaries will
have an equal, undivided interest in all such Restricted Share Units. 
 12. Should a beneficiary die after the Participant but before the
Restricted Share Unit is paid, such beneficiary’s rights and interest in the Award will be transferable by the beneficiary’s last will and testament or by the laws of descent and distribution. A named beneficiary who predeceases the
Participant will obtain no rights or interest in a Restricted Share Unit, nor will any person claiming on behalf of such individual. Unless otherwise specifically indicated by the Participant on the beneficiary designation form, beneficiaries
designated by class (such as “children,” “grandchildren,” etc.) will be deemed to refer to the members of the class living at the time of the Participant’s death, and all members of the class will be deemed to take
“per capita.” 
 13. If a Participant does not designate a beneficiary or if the Company does not permit a beneficiary
designation, the Restricted Share Units at the time of death of the Participant will be paid to the Participant’s legal heirs pursuant to the Participant’s last will and testament or by the laws of descent and distribution. 

Adjustments 
 14. In the event of
an Equity Restructuring, the Committee will equitably adjust the Restricted Share Unit as it deems appropriate to reflect the Equity Restructuring, which may include (i) adjusting the number and type of securities subject to the Restricted
Share Unit; and (ii) adjusting the terms and conditions of the Restricted Share Unit. The 

  
 3 

 
adjustments provided under this paragraph 14 will be nondiscretionary and final and binding on all interested parties, including the affected Participant and the Company; provided that the
Committee will determine whether an adjustment is equitable. 
 Repayment/Forfeiture 

15. Notwithstanding anything to the contrary herein, pursuant to Section 15(e) of the Plan the Committee has full power and authority, to
the extent permitted by governing law, to determine that the Restricted Share Unit will be canceled or suspended at any time prior to a Change in Control: (i) if the Participant, without the consent of the Committee, while employed by the
Company or a Subsidiary or after termination of such employment, becomes associated with, employed by, renders services to or owns any interest (other than an interest of up to 5% in a publicly traded company or any other nonsubstantial interest, as
determined by the Committee) in any business that is in competition with the Company or any Subsidiary; (ii) in the event of any willful conduct by the Participant which is, or might reasonably be expected to be, injurious to, or adverse to the
best interests of, the Company or any Affiliate, monetarily, or otherwise, including, but not limited to, its reputation or standing in its industry; (iii) in the event of the Participant’s misconduct described in Section 15(f) of the
Plan; or (iv) in order to comply with applicable laws as described in Section 15(h) of the Plan. 
 Further, as an additional
condition of receiving the Restricted Share Unit, the Participant agrees that the Restricted Share Unit and any benefits or proceeds the Participant may receive hereunder shall be subject to forfeiture and/or repayment to the Company to the extent
required (i) under the terms of the Company’s Compensation Recovery Policy, as it may be amended from time to time, and Section 15(f) of the Plan, (ii) under the terms of any other recoupment or “clawback” policy
adopted by the Company to comply with applicable laws or with the Company’s Corporate Governance Guidelines or other similar requirements, as such policy may be amended from time to time (and such requirements shall be deemed incorporated into
the Award Agreement without the Participant’s consent) or (iii) to comply with any requirements imposed under applicable laws and/or the rules and regulations of the securities exchange or inter-dealer quotation system on which the Shares
are listed or quoted, including, without limitation, pursuant to Section 954 of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010. Further, if the Participant receives any amount in excess of what the Participant should
have received under the terms of the Restricted Share Unit for any reason (including without limitation by reason of a financial restatement, mistake in calculations or administrative error), all as determined by the Committee, then the Participant
shall be required to promptly repay any such excess amount to the Company. 
 Miscellaneous Provisions 

16. Stock Exchange Requirements; Applicable Laws. Notwithstanding anything to the contrary in the Award Agreement, no Shares issuable
upon payment of the Restricted Share Units, and no certificate representing all or any part of such Shares, shall be issued or delivered if, in the opinion of counsel to the Company, such issuance or delivery would cause the Company to be in
violation of, or to incur liability under, any securities law, or any rule, regulation or procedure of any U.S. national securities exchange upon which any securities of the Company are listed, or any listing agreement with any such securities
exchange, or any other requirement of law or of any administrative or regulatory body having jurisdiction over the Company or a Subsidiary. 

17. Non-Transferability. The Restricted Share Units are
non-transferable and may not be assigned, alienated, pledged, attached, sold or otherwise transferred or encumbered by the Participant other than by will or the laws of descent and distribution and any such
purported assignment, alienation, pledge, attachment, sale, transfer or encumbrance shall be void and unenforceable against the Company; provided, that, the designation of a beneficiary shall not constitute an assignment, alienation, pledge,
attachment, sale, transfer or encumbrance. 

  
 4 

 18. Shareholder Rights. No person or entity shall be entitled to vote, receive
dividends or be deemed for any purpose the holder of any Shares until the Restricted Share Unit shall have vested and been paid in the form of Shares in accordance with the provisions of the Award Agreement. 

19. Notices. Any notice required or permitted under the Award Agreement shall be in writing and shall be deemed sufficient when
delivered personally or sent by confirmed email, telegram, or fax or five days after being deposited in the mail, as certified or registered mail, with postage prepaid, and addressed to the Company at the Company’s principal corporate offices
or to the Participant at the address maintained for the Participant in the Company’s records or, in either case, as subsequently modified by written notice to the other party. 

20. Severability and Judicial Modification. If any provision of the Award Agreement is held to be invalid or unenforceable under the
applicable laws of any country, state, province, territory or other political subdivision or the Company elects not to enforce such restriction, the remaining provisions shall remain in full force and effect and the invalid or unenforceable
provision shall be modified only to the extent necessary to render that provision valid and enforceable to the fullest extent permitted by law. If the invalid or unenforceable provision cannot be, or is not, modified, that provision shall be severed
from the Award Agreement and all other provisions shall remain valid and enforceable. 
 21. Successors. The Award Agreement shall be
binding upon and inure to the benefit of the Company and its successors and assigns, on the one hand, and the Participant and his or her heirs, beneficiaries, legatees and personal representatives, on the other hand. 

22. Appendices. Notwithstanding any provisions in the Award Agreement, for Participants residing and/or working outside the United
States, the Restricted Share Unit shall be subject to the additional terms and conditions set forth in Appendix A to the Award Agreement and to any special terms and conditions for the Participant’s country set forth in Appendix B to the Award
Agreement. Moreover, if the Participant relocates outside the United States or relocates between the countries included in Appendix B, the additional terms and conditions set forth in Appendix A and the special terms and conditions for such country
set forth in Appendix B will apply to the Participant, to the extent the Company determines that the application of such terms and conditions is necessary or advisable for legal or administrative reasons. The Appendices constitute part of the Award
Agreement. 
 23. Imposition of Other Requirements. The Company reserves the right to impose other requirements on the
Participant’s participation in the Plan, on the Restricted Share Unit and on any Shares acquired under the Plan, to the extent the Company determines it is necessary or advisable for legal or administrative reasons, and to require the
Participant to sign any additional agreements or undertakings that may be necessary to accomplish the foregoing. 
 24. Compliance with
Code Section 409A. It is intended that the Restricted Share Right granted pursuant to the Award Agreement be compliant with Section 409A of the Code and the Award Agreement shall be interpreted, construed and operated to
reflect this intent. Notwithstanding the foregoing, the Award Agreement and the Plan may be amended at any time, without the consent of any party, to the extent necessary or desirable to satisfy any of the requirements under Section 409A of the
Code, but the Company shall not be under any obligation to make any such amendment. Further, the Company and its Subsidiaries do not make any representation to the Participant that the Restricted Share Right granted pursuant to the Award Agreement
satisfies the requirements of Section 409A of the Code, and the Company and its Subsidiaries will have no liability or other obligation to indemnify or hold harmless the Participant or any other party for any tax, additional tax, interest or
penalties that the Participant or any other party may incur in the event that any provision of the Award Agreement or any amendment or modification thereof or any other action taken with respect thereto, is deemed to violate any of the requirements
of Section 409A of the Code. 

  
 5 

 25. Waiver. A waiver by the Company of breach of any provision of the Award Agreement
shall not operate or be construed as a waiver of any other provision of the Award Agreement, or of any subsequent breach by the Participant or any other Participant. 

26. No Advice Regarding Award. The Company is not providing any tax, legal or financial advice, nor is the Company making any
recommendations regarding the Participant’s participation in the Plan, or the Participant’s acquisition or sale of the underlying Shares. The Participant is hereby advised to consult with the Participant’s own personal tax, legal and
financial advisors regarding the Participant’s participation in the Plan before taking any action related to the Plan. 
 27.
Governing Law; Dispute Resolution. The Restricted Share Unit and the provisions of the Award Agreement and all determinations made and actions taken thereunder, to the extent not otherwise governed by the laws of the United States, shall be
governed by the laws of the State of Delaware, United States of America, without reference to principles of conflict of laws, and construed accordingly. Any claim, dispute or controversy arising under or in connection with the Restricted Share Unit
and the provisions of the Award Agreement, shall be settled exclusively by arbitration in Pittsburgh, Pennsylvania. All claims, disputes and controversies shall be submitted to the CPR Institute for Dispute Resolution (“CPR”) in accordance
with the CPR’s rules then in effect; provided, however, that the evidentiary standards set forth in this Agreement shall apply. The claim, dispute or controversy shall be heard and decided by three (3) arbitrators selected from CPR’s
employment panel. The arbitrators’ decision shall be final and binding on all parties. Judgment may be entered on the arbitrators’ award in any court having jurisdiction. 

28. Electronic Delivery and Acceptance. The Company may, in its sole discretion, decide to deliver any documents related to current or
future participation in the Plan by electronic means. The Participant hereby consents to receive such documents by electronic delivery and agrees to participate in the Plan through an on-line or electronic
system established and maintained by the Company or a third party designated by the Company. 
 29. Entire Agreement. The Award
Agreement and the Plan embody the entire understanding and agreement of the parties with respect to the subject matter hereof, and no promise, condition, representation or warranty, express or implied, not stated or incorporated by reference herein,
shall bind either party hereto. 
 Acceptance of Award 

30. As permitted by Section 15(c) of the Plan, receipt of this Restricted Share Unit award is subject to the Participant’s acceptance
of the Award and the terms of this Award Agreement and the Plan through Fidelity NetBenefits® website https://nb.fidelity.com/ and/or through such other procedures as may be required
by the Company (Participant’s “Acceptance”). To avoid forfeiture of the Award, the Participant must provide such Acceptance within 6 months of the grant date of the Award. The date as of which the
Participant’s Restricted Share Unit award shall be forfeited, if the Participant has not provided such Acceptance, will generally be set forth in the Participant’s account at Fidelity NetBenefits® website. If the Participant does not provide Acceptance within this 6 month period, the Award will be cancelled in accordance with any administrative procedures adopted under the Plan. 

Performance Feature 
 31. If the
vesting of a Restricted Share Unit is subject to a performance condition, the following additional terms and conditions will apply to that Award: 
  

	 	•	 	 The Participant will have the right to receive from 0% to 200% of the number of Shares indicated on the grant
date, based on achievement of performance goals established by the Committee for that Award. 

  
 6 

	 	•	 	 The performance period is three fiscal years of the Company. Attainment of performance goals for the
three-year period will be determined or certified, as applicable, by the Committee on a date as soon as practicable following the end of the performance period (the “Determination Date”). 

 

	 	•	 	 Notwithstanding paragraph 2 of the Award Agreement, the vesting date of the Award shall be the later of the
date set forth in paragraph 2 and the Determination Date. To vest in the Award, the Participant must remain employed with the Company or a Subsidiary until such vesting date, except as otherwise set forth in paragraph 4. In any case, except where
settlement of the Award is made upon a Change in Control within the meaning of Treas. Reg. § 1.409A-3(i)(5), in no event will settlement of the Award occur outside of the time period set forth in
paragraph 2. 

  

	 	•	 	 In the event of termination of the Participant’s employment with the Company (including its Subsidiaries)
before the vesting of the Restricted Share Unit by reason of death, disability, retirement or divestiture, each as described in paragraph 4, settlement of the Restricted Share Unit will be based on the extent to which the performance goals
established by the Committee have been attained following the end of the performance period. 

  

	 	•	 	 In the event of a Change in Control, the performance feature of the Award will cease to apply and the Award
will be converted into a time-based award in accordance with the formula set forth in Section 12(a)(v) of the Plan. The vesting and settlement of such Award will then be governed in accordance with paragraph 4.

 APPENDIX A 

TO THE ARCONIC CORPORATION 

2020 Stock Incentive Plan 

Global Restricted Share Unit Award Agreement 

For Non-U.S. Participants 

This Appendix A contains additional (or, if so indicated, different) terms and conditions that govern the Restricted Share Units if the
Participant resides and/or works outside of the United States. Capitalized terms used but not defined herein shall have the same meanings assigned to them in the Plan and the Global Restricted Share Unit Award Agreement (the “Award
Agreement”). 
 A. Termination. This provision supplements paragraph 3 of the Award Agreement. 

The Company will determine when the Participant is no longer providing services for purposes of the Restricted Share Units (including whether
the Participant may still be considered to be providing services while on a leave of absence). 
 B. Responsibility for Taxes. This
provision replaces paragraph 6 of the Award Agreement (except if the Participant is subject to the short-swing profit rules of Section 16(b) of the Securities Exchange Act of 1934, as amended). 

The Participant acknowledges that, regardless of any action taken by the Company or, if different, the Subsidiary that employs the Participant
(the “Employer”), the ultimate liability for all income tax, social insurance, payroll tax, fringe benefits tax, payment on account or other tax-related items related to the Participant’s
participation in the Plan and legally applicable to the Participant (“Tax-Related Items”) is and remains the Participant’s responsibility and may exceed the amount actually withheld by the
Company or the Employer. The Participant further acknowledges that the Company and/or the Employer (a) make no representations or undertakings regarding the treatment of any Tax-Related Items in
connection with any aspect of these Restricted Shares Units, including, but not limited to, the grant, vesting or settlement of Restricted Shares Units, the subsequent sale of Shares acquired pursuant to the Restricted Share Unit and the receipt of
any dividends or dividend equivalents; and (b) do not commit to and are under no obligation to structure the terms of the Restricted Share Units or any aspect of the Restricted Share Units to reduce or eliminate the Participant’s liability
for Tax-Related Items or achieve any particular tax result. The Participant shall not make any claim against the Company, the Employer or any other Subsidiary, or their respective board, officers or employees
related to Tax-Related Items arising from this Award. Furthermore, if the Participant has become subject to tax in more than one jurisdiction, the Participant acknowledges that the Company and/or the Employer
(or former employer, as applicable) may be required to withhold or account for Tax-Related Items in more than one jurisdiction. 

Prior to any relevant taxable or tax withholding event, as applicable, the Participant will pay or make adequate arrangements satisfactory to
the Company and/or the Employer to satisfy all Tax-Related Items. In this regard, the Participant authorizes the Company and/or the Employer, or their respective agents, at their discretion, to satisfy their
withholding obligations with regard to all Tax-Related Items by one or a combination of the following: (i) requiring a cash payment from the Participant; (ii) withholding from the Participant’s
wages or other cash compensation paid to the Participant by the Company and/or the Employer, (iii) withholding from the proceeds of the sale of Shares acquired pursuant to the Restricted Share Units, either through a voluntary sale or through a
mandatory sale arranged by the Company (on the Participant’s behalf pursuant to this authorization without further consent); (iv) withholding from the Shares subject to Restricted Share Units; and/or (v) any other method of withholding
determined by the Company and permitted by applicable law. 

  
 A-1 

 Depending on the withholding method, the Company may withhold or account for Tax-Related Items by considering applicable minimum statutory withholding rates or other applicable withholding rates, including maximum applicable rates, in which case the Participant may receive a refund of any
over-withheld amount in cash (with no entitlement to the Share equivalent) or, if not refunded, the Participant may seek a refund from the local tax authorities. If the obligation for Tax-Related Items is
satisfied by withholding in Shares, the Participant is deemed, for tax purposes, to have been issued the full number of Shares subject to the vested Restricted Shares Units, notwithstanding that a number of the Shares is held back solely for the
purpose of paying the Tax-Related Items. 
 Finally, the Participant shall pay to the Company and/or
the Employer any amount of Tax-Related Items that the Company and/or the Employer may be required to withhold or account for as a result of the Participant’s participation in the Plan that cannot be
satisfied by the means previously described. The Company may refuse to issue or deliver the Shares or the proceeds of the sale of Shares if the Participant fails to comply with his or her obligations in connection with the Tax-Related Items. 
 C. Nature of Award. In accepting the Restricted Share Units, the Participant
acknowledges, understands and agrees that: 
 a. the Plan is established voluntarily by the Company, is discretionary in
nature and may be modified, amended, suspended, or terminated by the Company at any time, to the extent permitted by the Plan; 

b. this Award of Restricted Share Units is exceptional, voluntary and occasional and does not create any contractual or other
right to receive future Restricted Share Units, or benefits in lieu of Restricted Share Units, even if Restricted Share Units have been granted in the past; 

c. all decisions with respect to future Restricted Share Units or other Awards, if any, will be at the sole discretion of the
Company; 
 d. this Award of Restricted Share Units and the Participant’s participation in the Plan shall not create a
right to, or be interpreted as forming or amending an employment or service contract with the Company and shall not interfere with the ability of the Employer to terminate the Participant’s employment contract (if any) at any time; 

e. the Participant’s participation in the Plan is voluntary; 

f. this Award of Restricted Share Units and the Shares acquired under the Plan, and the income from and value of same, are not
intended to replace any pension rights or compensation; 
 g. this Award of Restricted Share Units and the Shares acquired
under the Plan, and the income from and value of same, are not part of normal or expected compensation or salary for any purposes, including, without limitation, calculating any severance, resignation, termination, redundancy, dismissal, end-of-service payments, bonuses, long-service awards, pension or retirement or welfare benefits or similar payments; 

h. the future value of the Shares subject to the Restricted Share Units is unknown, indeterminable and cannot be predicted with
certainty; 
 i. unless otherwise agreed with the Company, Restricted Share Units and the Shares acquired under the Plan, and
the income from and value of same, are not granted as consideration for, or in connection with, the service the Participant may provide as a director of any Subsidiary; 

  
 A-2 

 j. no claim or entitlement to compensation or damages shall arise from
forfeiture of any portion of this Award of Restricted Share Units resulting from termination of the Participant’s employment and/or service relationship (for any reason whatsoever and regardless of whether later found to be invalid or in breach
of applicable laws in the jurisdiction where the Participant is employed or the terms of the Participant’s employment agreement, if any); 

k. unless otherwise provided in the Plan or by the Company in its discretion, this Award of Restricted Share Units and the
benefits under the Plan evidenced by this Award Agreement do not create any entitlement to have this Award of Restricted Share Units or any such benefits transferred to, or assumed by, another company nor to be exchanged, cashed out or substituted
for, in connection with any corporate transaction affecting the Shares; and 
 l. neither the Company, the Employer nor any
other Subsidiary shall be liable for any foreign exchange rate fluctuation between the Participant’s local currency and the United States Dollar that may affect the value of the Restricted Share Units or of any amounts due to the Participant
pursuant to the Restricted Share Units or the subsequent sale of any Shares acquired under the Plan. 
 D. Data Privacy.
To participate in the Plan, the Participant will need to review the information provided in this paragraph and, where applicable, declare the Participant’s consent to the processing of personal data by Arconic Corporation and third
parties noted below. Acceptance of the Award shall constitute Participant’s consent to the processing of personal data. 

a. EEA+ Controller and Contact Information. If the Participant is based in the European Union (“EU”), the
European Economic Area, Switzerland or, the United Kingdom (collectively “EEA+”), the Participant should note that Arconic Corporation, with its registered address at 201 Isabella Street, Suite 200, Pittsburgh, Pennsylvania 15212-5872,
United States of America, is the controller responsible for the processing of the Participant’s personal data in connection with the Award Agreement and the Plan. Questions about the processing of personal data can be made to the Arconic
Privacy Office at privacy@arconic.com. 
 b. Data Collection and Usage. In connection with the administration
of the Plan, Arconic Corporation collects, processes, uses and transfers certain personally-identifiable information about the Participant, which may include the Participant’s name, home address and telephone number, email address, date of
birth, social insurance, passport number or other identification number, salary, nationality, job title, details of all Awards or any other awards granted, canceled, exercised, settled, vested, unvested or outstanding in the Participant’s favor
and additional similar or related data, which Arconic Corporation receives from the Participant or the entity that employs the Participant (“Personal Data”). Specifically, Arconic Corporation collects, processes and uses Personal Data
for the purposes of performing its contractual obligations under this Award Agreement, implementing, administering and managing the Participant’s participation in the Plan and facilitating compliance with applicable tax and securities law. 

If the Participant is based in the EEA+, the legal basis, where required, for the processing of Personal Data by Arconic Corporation is
the necessity for Arconic Corporation to (i) perform its contractual obligations under this Agreement, (ii) comply with legal obligations established in the EEA+, and/or (iii) pursue the legitimate interest of complying with legal
obligations established outside of the EEA+.
 If the Participant is based outside of the EEA+, the legal basis, where
required, for the processing of Data by Arconic Corporation is the Participant’s consent, as further described below. 

c. Plan Administration Service Providers. Arconic Corporation may transfer Personal Data to Fidelity or other
independent service providers that assist Arconic Corporation with the implementation, administration and management of the Plan (the “Plan Administrator”). The processing of Personal Data will take place through both

  
 A-3 

 
electronic and non-electronic means. Personal Data will only be accessible by those individuals requiring access to it for purposes of implementing,
administering and operating the Plan. 
 d. International Data Transfers. Arconic Corporation and the Plan
Administrator are based in the United States. The country where the Participant lives may have different data privacy laws and protections than the United States. In particular, the United States does not have the same level of protections for
personal data as countries in the EEA+. The European Commission requires U.S. companies to protect personal data leaving the EEA+ by certifying compliance with the EU-U.S. privacy shield program or
implementing other safeguards such as the Standard Contractual Clauses adopted by the EU Commission. Arconic Corporation is certified under the EU-U.S. privacy shield program. 

If the Participant is based in the EEA+, Personal Data will be transferred from the EEA+ to Arconic Corporation based on the
certification under the EU-U.S. privacy shield program. Personal Data will be transferred onward from Arconic Corporation to the Plan Administrator based on the Participant’s consent, as further described
below. 
 If the Participant is based in a jurisdiction outside of the EEA+, Personal Data will be transferred from the
Participant’s jurisdiction to Arconic Corporation and onward from Arconic Corporation to the Plan Administrator based on the Participant’s consent, as further described below. 

e. Data Retention. Arconic Corporation will use Personal Data only as long as necessary to implement, administer and
manage the Participant’s participation in the Plan, or as required to comply with legal or regulatory obligations, including tax and securities laws. When Arconic Corporation no longer needs Personal Data for any of these purposes, Arconic
Corporation will remove it from its systems.
 f. Voluntariness and Consequences of Consent Denial or Withdrawal.
Participation in the Plan is voluntary and the Participant is providing the consents herein on a purely voluntary basis. The Participant may withdraw the Participant’s consent at any time, with future effect and for any or no reason. If the
Participant does not consent, or if the Participant later seeks to withdraw the Participant’s consent, the Participant’s salary from or employment or service relationship with the Participant’s employer will not be affected. The only
consequence of denying or withdrawing consent is that Arconic Corporation would not be able to grant Awards to the Participant under the Plan or administer or maintain the Participant’s participation in the Plan. If the Participant withdraws
the Participant’s consent, Arconic Corporation will stop processing the Participant’s Personal Data for the purposes stated above unless to the extent necessary to comply with tax or other legal obligations in connection with Awards
granted before the Participant withdrew the Participant’s consent. 
 g. Data Subject Rights. The Participant may
have a number of rights under data privacy laws in the Participant’s jurisdiction. Subject to the conditions set out in the applicable law and depending on where the Participant is based, such rights may include the right to
(i) request access to, or copies of, Personal Data processed by Arconic Corporation, (ii) rectification of incorrect Personal Data, (iii) deletion of Personal Data, (iv) restrict the processing of Personal Data, (v) object
to the processing of Personal Data for legitimate interests, (vi) portability of Personal Data, (vii) lodge complaints with competent authorities in the Participant’s jurisdiction, and/or to (viii) receive a list with the names
and addresses of any potential recipients of Personal Data. To receive clarification regarding these rights or to exercise these rights, the Participant can contact the Arconic Privacy office at privacy@arconic.com. 

h. Necessary Disclosure of Personal Data. The Participant understands that providing Arconic Corporation with Personal
Data is necessary for the performance of this Award Agreement and that the Participant’s refusal to provide Personal Data would make it impossible for Arconic Corporation to perform its contractual obligations and would affect the
Participant’s ability to participate in the Plan. 

  
 A-4 

 i. Declaration of Consent. By accepting the Participant’s Award,
the Participant is declaring that the Participant unambiguously consents to the collection, use and transfer, in electronic or other form, of the Participant’s Personal Data, as described above and in any other grant materials, by and among, as
applicable, the entity that employs the Participant, Arconic Corporation, any Subsidiary and any service provider involved in plan administration for the exclusive purpose of implementing, administering and managing the
Participant’s participation in the Plan. The Participant understands that the Participant may, at any time, refuse or withdraw the consents herein, in any case without cost, by contacting in writing the Arconic Privacy Office at
privacy@arconic.com. If the Participant does not consent or later seek to revoke the Participant’s consent, the Participant’s employment status or service with the entity that employs the Participant will not be affected; the
only consequence of refusing or withdrawing consent is that Arconic Corporation would not be able to grant the Award or any other equity award to the Participant or administer or maintain such awards. Therefore, the Participant understands that
refusing or withdrawing consent will affect the Participant’s ability to participate in the Plan. For more information on the consequences of refusal to consent or withdrawal of consent, the Participant should contact
privacy@arconic.com. 
 E. Retirement. Notwithstanding paragraph 4 of the Award Agreement, if the Company receives an
opinion of counsel that there has been a legal judgment and/or legal development in the Participant’s jurisdiction that would likely result in the favorable treatment applicable to the Restricted Share Units pursuant to paragraph 4 being deemed
unlawful and/or discriminatory, then the Company will not apply the favorable treatment at the time of the Participant’s retirement, and the Restricted Share Units will be treated as set forth in the remaining provisions of paragraph 4 of the
Award Agreement. 
 F. Language. The Participant acknowledges that he or she is sufficiently proficient in English to understand the
terms and conditions of the Award Agreement. Furthermore, if the Participant has received this Award Agreement, or any other document related to this Award of Restricted Share Units and/or the Plan translated into a language other than English and
if the meaning of the translated version is different than the English version, the English version will control. 
 G. Insider Trading
Restrictions/Market Abuse Laws. The Participant acknowledges that, depending on his or her country, the broker’s country, or the country in which the Shares are listed, the Participant may be subject to insider trading restrictions and/or
market abuse laws in applicable jurisdictions, which may affect his or her ability to accept, acquire, sell, or attempt to sell or otherwise dispose of Shares or rights to Shares (e.g., Restricted Share Units), or rights linked to the value
of Shares, during such times as he or she is considered to have “inside information” regarding the Company (as defined by applicable laws or regulations in the applicable jurisdictions, including the United States and the
Participant’s country). Local insider trading laws and regulations may prohibit the cancellation or amendment of orders the Participant placed before possessing inside information. Furthermore, the Participant may be prohibited from
(i) disclosing the inside information to any third party, including fellow employees (other than on a “need to know” basis) and (ii) “tipping” third parties or causing them to otherwise buy or sell securities. Any
restrictions under these laws or regulations are separate from and in addition to any restrictions that may be imposed under any applicable Company insider trading policy. The Participant acknowledges that it is his or her responsibility to comply
with any applicable restrictions, and the Participant should consult his or her personal advisor on this matter. 
 H. Foreign

 APPENDIX B 

TO THE ARCONIC CORPORATION 

2020 Stock Incentive Plan 

Global Restricted Share Unit Award Agreement 

For Non-U.S. Participants 

Capitalized terms used but not defined in this Appendix B have the meanings set forth in the Plan and the Global Restricted Share Unit Award
Agreement (the “Award Agreement”). 
 Terms and Conditions 

This Appendix B includes special terms and conditions that govern Restricted Share Units if the Participant resides and/or works in one of the
countries listed below. 
 If the Participant is a citizen or resident of a country other than the country in which the Participant is
currently residing and/or working, or if the Participant transfers to another country after the grant of Restricted Share Units or is considered a resident of another country for local law purposes, the Committee shall, in its discretion, determine
to what extent the special terms and conditions contained herein shall be applicable to the Participant. 
 Notifications 

This Appendix B also includes information regarding exchange controls, tax and certain other issues of which the Participant should be aware
with respect to participation in the Plan. The information is based on the securities, exchange control, tax and other laws in effect in the respective countries as of April 2020. Such laws are often complex and change frequently. As a result, the
Company strongly recommends that the Participant not rely on the information in this Appendix B as the only source of information relating to the consequences of participation in the Plan because the information may be out of date at the time the
Participant sells Shares acquired under the Plan. 
 In addition, the information contained herein is general in nature and may not apply to
the Participant’s particular situation and the Company is not in a position to assure the Participant of any particular result. Accordingly, the Participant should seek appropriate professional advice as to how the relevant laws in the
Participant’s country may apply to his or her situation. 
 Finally, if the Participant is a citizen or resident of a country other
than the country in which the Participant currently works and/or resides, or if the Participant transfers to another country after the grant of the Restricted Share Unit, or is considered a resident of another country for local law purposes, the
information contained herein may not be applicable to the Participant in the same manner.

 Award
Settled Only in Shares. Notwithstanding any discretion in the Plan, the Award of Restricted Share Units shall be settled in Shares only. The Participant is not entitled to receive a cash payment pursuant to the Award. 

Termination of Service. The following provision replaces paragraph A “Termination” of Appendix A: 

For purposes of the Restricted Share Units, in the event of termination of the Participant’s employment relationship (whether or not in

Participant is no longer actively employed or (ii) the date upon which the Participant receives written notice of termination from the Company or the Employer. The Company shall have the exclusive discretion to determine when the Participant is
no longer actively employed or when the Participant has received notice of such termination for purposes of the Restricted Share Unit award. Notwithstanding the foregoing, if applicable employment standards legislation explicitly requires continued
entitlement to vesting during a statutory notice period, the Participant’s right to vest in the Restricted Share Unit award under the Plan, if any, will terminate effective as of the last day of the Participant’s minimum statutory notice
period, but the Participant will not earn or be entitled to pro-rated vesting if the vesting date falls after the end of the Participant’s statutory notice period, nor will the Participant be entitled to
any compensation for lost vesting. 
 The Following Provisions Apply for Participants Resident in Quebec: 

Consent to Receive Information in English. The Participant acknowledges that it is the express wish of the parties that this Award

 Securities Law Information. The Participant acknowledges that he or she is permitted
to sell the Shares acquired under the Plan through the designated broker appointed by the Company, provided the sale of the Shares takes place outside of Canada through facilities of a stock exchange on which the Shares are listed (i.e., the
NYSE). 
 Foreign Asset/Account Reporting Information. Canadian residents are required to report to the tax authorities certain
foreign property (included Restricted Share Units) on form T1135 (Foreign Income Verification Statement) if the total cost of the foreign property exceeds C$100,000 at any time in the year. The form must be filed by April 30 of the following
year. Restricted Share Units must be reported—generally at a nil cost—if the C$100,000 cost threshold is exceeded because of other foreign property the Participant holds. If Shares are acquired, their cost generally is the adjusted cost
base (“ACB”) of the Shares. The ACB would normally equal the fair market value of the Shares at vesting, but if the Participant owns other Shares, this ACB may have to be averaged with the ACB of the other Shares. The Participant should
consult with his or her personal legal advisor to ensure compliance with applicable reporting obligations. 
 CHINA 

Terms and Conditions 
 The following terms and
conditions will apply to Participants who are subject to exchange control restrictions and regulations in the People’s Republic of China (“the PRC”), including the requirements imposed by the State Administration of Foreign Exchange
(“SAFE”), as determined by the Company in its sole discretion: 
 Award Conditioned on Satisfaction of Regulatory
Obligations. Notwithstanding anything to the contrary in the Award Agreement, settlement of the Restricted Share Units is conditioned on the Company’s obtaining a registration of the Plan with SAFE and on the continued effectiveness of such
registration (the “SAFE Registration Requirement”). If, for any reason, the Company does not complete or maintain such registration, no Shares subject to the Restricted Shares Units for which a registration is not completed or maintained
shall be issued. In this case, the Company retains the discretion to settle any Restricted Share Units for which the vesting conditions, but not the SAFE Registration Requirement, have been met in cash paid through local payroll in an amount equal
to the market value of the Shares subject to the Restricted Share Units less any Tax-Related Items. 

Shares Must Remain With Company’s Designated Broker. To the extent that the Participant receives any Shares upon
settlement of the Restricted Share Units, the Participant must hold such Shares with the Company’s designated broker until the Shares are sold. The limitation shall apply to all Shares issued to the Participant under the Plan, whether or not
the Participant remains employed with the Company or its Subsidiaries. 
 Forced Sale of Shares. To the extent that the
Participant receives any Shares upon settlement of the Restricted Share Units, the Company has the discretion to arrange for the sale of such Shares either immediately upon settlement or at any time thereafter. In any event, if the
Participant’s employment is terminated, the Participant will be required to sell all Shares acquired upon settlement of the Restricted Share Units within such time period as required by the Company in accordance with SAFE requirements. Any
Shares remaining in the Participant’s brokerage account at the end of this period shall be sold by the broker (on behalf of the Participant and the Participant hereby authorizes such sale). The Participant agrees to sign any additional
agreements, forms and/or consents that reasonably may be requested by the Company (or the Company’s designated broker) to effectuate the sale of Shares (including, without limitation, as to the transfer of the sale proceeds and other exchange
control matters noted below) and shall otherwise cooperate with the Company with respect to such matters. The Participant acknowledges that neither the Company nor the designated broker is under any obligation to arrange for the sale of Shares at
any particular price (it being understood that the sale will occur in the market) and that broker’s fees and similar expenses may be incurred in any such sale. 

  
 B-3 

 
In any event, when the Shares are sold, the sale proceeds, less any tax withholding, any broker’s fees or commissions, and any similar expenses of the sale will be remitted to the
Participant in accordance with applicable exchange control laws and regulations. 
 Exchange Control Restrictions. To the extent that
the Participant receives any Shares upon settlement of the Restricted Share Units, the Participant understands and agrees that the Participant will be required to immediately repatriate to China the proceeds from the sale of such Shares and
any cash dividends paid on such Shares. The Participant further understands that such repatriation of proceeds may need to be effected through a special bank account established by the Company (or a Subsidiary), and the Participant hereby consents
and agrees that any sale proceeds and cash dividends may be transferred to such special account by the Company (or a Subsidiary) on the Participant’s behalf prior to being delivered to the Participant and that no interest shall be paid with
respect to funds held in such account. 
 Any proceeds from the sale of Shares may be paid to the Participant in U.S. dollars or local
currency at the Company’s discretion. If the proceeds are paid to the Participant in U.S. dollars, Participant understands that a U.S. dollar bank account in China must be established and maintained so that the proceeds may be deposited into
such account. If the proceeds are paid to the Participant in local currency, the Participant acknowledges that the Company (or its Subsidiaries) are under no obligation to secure any particular exchange conversion rate and that the Company (or its
Subsidiaries) may face delays in converting the proceeds to local currency due to exchange control restrictions. The Participant agrees to bear any currency fluctuation risk between the time the Shares are sold and the net proceeds are converted
into local currency and distributed to the Participant. The Participant further agrees to comply with any other requirements that may be imposed by the Company in the future in order to facilitate compliance with exchange control requirements in
China. 
 Administration. The Company (or its Subsidiaries) shall not be liable for any costs, fees, lost interest or dividends or
other losses that the Participant may incur or suffer resulting from the enforcement of the terms of this Appendix or otherwise from the Company’s operation and enforcement of the Plan, the Award Agreement, the Award in accordance with any
applicable laws, rules, regulations and requirements.

 The Participant understands and agrees that, as a condition of the grant of the Restricted

 B-7 

 
will not be entitled to continue vesting in any RSUs upon cessation of the Participant’s employment or service and any unvested Restricted Share Units shall be forfeited without entitlement
to the underlying Shares or to any amount as indemnification in the event of a termination, including, but not limited to: resignation, disciplinary dismissal adjudged to be with cause, disciplinary dismissal adjudged or recognized to be without

under Article 40 of the Workers’ Statute, Article 50 of the Workers’ Statute, unilateral withdrawal by the Employer, and under Article 10.3 of Royal Decree 1382/1985. 

The Participant understands that the Company has unilaterally, gratuitously and in its sole discretion decided to grant Restricted Share Units
under the Plan to individuals who may be Employees of the Company or a Subsidiary. The decision is limited and entered into based upon the express assumption and condition that any Restricted Share Units will not economically or otherwise bind the
Company or any Subsidiary, including the Employer, on an ongoing basis, other than as expressly set forth in the Award Agreement. Consequently, the Participant understands that the Restricted Share Units are granted on the assumption and condition
that the Restricted Share Units shall not become part of any employment or service agreement (whether with the Company or any Subsidiary, including the Employer) and shall not be considered a mandatory benefit, salary for any purpose (including
severance compensation) or any other right whatsoever. Furthermore, the Participant understands and freely accepts that there is no guarantee that any benefit whatsoever shall arise from the grant of Restricted Share Units, which is gratuitous and
discretionary, since the future value of the Restricted Share Units and the underlying Shares is unknown and unpredictable. The Participant also understands that the grant of Restricted Share Units would not be made but for the assumptions and
conditions set forth hereinabove; thus, the Participant understands, acknowledges and freely accepts that, should any or all of the assumptions be mistaken or any of the conditions not be met for any reason, the Restricted Share Unit and any right
to the underlying Shares shall be null and void.

Securities Law Information. A Restricted Share Unit is not considered to be a security under Spanish law. No “offer of securities
to the public”, as defined under Spanish law, has taken place or will take place in the Spanish territory with respect to the Restricted Share Units. No public offering prospectus has been nor will be registered with the Comisión
Nacional del Mercado de Valores (Spanish Securities Exchange Commission) (“CNMV”). Neither the Plan nor the Award Agreement constitute a public offering prospectus and they have not been, nor will they be, registered with the CNMV.

 Exchange Control Information. To participate in the Plan, the Participant must comply with exchange control regulations in Spain.
The acquisition of Shares upon vesting of the Restricted Share Units and subsequent sales of Shares must be declared for statistical purposes to the Dirección General de Comercio e Inversiones (the “DGCI”). Because the
Participant will not purchase or sell the Shares through the use of a Spanish financial institution, the Participant must make the declaration himself or herself by filing a Form D-6 with the DGCI. Generally,
the Form D-6 must be filed each January while the Shares are owned. In addition, the sale of Shares must also be declared on Form D-6 filed with the DGCI in January,
unless the sale proceeds exceed the applicable threshold, in which case, the filing is due within one month after the sale. 
 In addition,
the Participant may be required to declare electronically to the Bank of Spain any foreign accounts (including brokerage accounts held abroad), any foreign instruments (including any Shares acquired under the Plan) and any transactions with non-Spanish residents (including any payments of Shares made to the Participant by the 

  
 B-8 

 
Company) depending on the value of such accounts and instruments and the amount of the transactions during the relevant year as of December 31 of the relevant year. 

Foreign Asset/Account Reporting Information. The Participant is required to declare electronically to the Bank of Spain any securities
accounts (including brokerage accounts held abroad), as well as the Shares held in such accounts if the value of the transactions during the prior tax year or the balances in such accounts as of December 31 of the prior tax year exceed
€1,000,000. 
 Further, to the extent that the Participant holds Shares and/or has bank accounts outside Spain with a value in excess
of €50,000 (for each type of asset) as of December 31, the Participant will be required to report information on such assets on his or her tax return (tax form 720) for such year. After such Shares and/or accounts are initially reported,
the reporting obligation will apply for subsequent years only if the value of any previously-reported Shares or accounts increases by more than €20,000 or if the Participant sells or otherwise disposes of any previously-reported Shares or
accounts.

Responsibility for Taxes. The following supplements paragraph B “Responsibility for Taxes” of Appendix A: 

Without limitation to paragraph B “Responsibility for Taxes” of Appendix A, the Participant agrees that the Participant is liable
for all Tax-Related Items and hereby covenants to pay all such Tax-Related Items as and when requested by the Company or the Employer or by Her Majesty’s
Revenue & Customs (“HMRC”) (or any other tax authority or any other relevant authority). The Participant also agrees to indemnify and keep indemnified the Company and the Employer against any
Tax-Related Items that they are required to pay or withhold or have paid or will have to pay to HMRC (or any other tax authority or any other relevant authority) on the Participant’s behalf. 

Notwithstanding the foregoing, if the Participant is a Director or executive officer of the Company (within the meaning of Section 13(k)
of the U.S. Securities Exchange Act of 1934), the Participant may not be able to indemnify the Company or the Employer for the amount of any income tax not collected from or paid by the Participant, as it may be considered a loan. In this case, the
amount of any uncollected income tax may constitute a benefit to the Participant on which additional income tax and employee National Insurance contributions (“NICs”) may be payable. The Participant agrees to report and pay any income
tax due on this additional benefit directly to HMRC under the self-assessment regime and to pay the Employer for the value of the employee NICs due on this additional benefit, which the Company or the Employer may recover from the Participant by any
of the means referred to in the Award Agreement, including the Appendices.
