Attn: #ParticipantName#

Avient Corporation

Subject to the terms and conditions of the Avient Corporation 2020 Equity and Incentive Compensation Plan, as amended and restated effective May 11, 2023 (the “Plan”), and this letter agreement (this “Agreement”), the Compensation Committee of the Board of Directors (the “Committee”) of Avient Corporation (“Avient”) [or its authorized delegatee]1 has granted to you, as of #GrantDate#, the following award:

#QuantityGranted# restricted stock units (the “Restricted Stock Units”), which shall vest in accordance with the terms set forth in this Agreement. Each Restricted Stock Unit shall represent one hypothetical common share, par value US$0.01 per share, of Avient (a “Common Share”) and shall at all times be equal in value to one Common Share.

A copy of the Plan is available for your review through the Corporate Secretary’s office. Unless otherwise indicated, the capitalized terms used in this Agreement shall have the same meanings as set forth in the Plan.

(a)Subject to the provisions of the Plan and this Agreement, the Restricted Stock Units shall vest in substantially equal installments on each of the following dates: #VestDate_1#, #VestDate_2# and #VestDate_3# (each date, a “Vesting Date”, and the three-year vesting period from #GrantDate# until #VestDate_3#, the

“Restriction Period”), provided that you remain in the continuous employ of Avient or a Subsidiary on each such Vesting Date.

(b)Notwithstanding the provisions of Section 1(a) of this Agreement, (i) if a Change of Control occurs prior to the end of the Restriction Period, any Restricted Stock Units that remain unvested as of such Change of Control shall immediately vest upon such Change of Control, and (ii) if your employment with Avient or a Subsidiary terminates prior to the end of the Restriction Period due to (A) your retirement at age 55 or older with at least 10 years of service, (B) your retirement at age 58 or older with at least 5 years of service, (C) your permanent and total disability (as defined under the relevant disability plan or program of Avient or a Subsidiary in which you then participate), or (D) your death, you shall vest in a number of Restricted Stock Units equal to the product of (I) one-third of the total number of Restricted Stock Units subject to this Agreement, multiplied by (II) a fraction, the numerator of which is the number of days that have elapsed between the Vesting Date immediately preceding your termination date (or, in the event your employment terminates prior to the first Vesting Date, #GrantDate#) and the date your employment by Avient or a Subsidiary terminates, and the denominator of which is 365. The remaining portion of the Restricted Stock Units will be forfeited.

(c)Notwithstanding the provisions of Sections 1(a) and 1(b) of this Agreement and to the extent permitted by applicable law, a number of Restricted Stock Units may vest and become payable prior to a Vesting Date or other vesting event described in Section 1(b) of this Agreement in an amount that is sufficient to cover any employment tax that becomes payable by you with respect to the Restricted Stock Units prior to such Vesting Date or other vesting event, as applicable.

2.Other Termination. If your employment with Avient or a Subsidiary terminates before the end of the Restriction Period for any reason other than as set forth in Section 1(b)(ii) of this Agreement and before a Change of Control occurs, all of the Restricted Stock Units that remain unvested as of the termination of your employment will be forfeited.

3.Payment of Restricted Stock Units.

(a)The Restricted Stock Units that vest pursuant to Section 1 of this Agreement will be paid in Common Shares transferred to you within 30 business days following the applicable Vesting Date; provided, however, that, subject to Section 3(b) of this Agreement, (i) in the event a Change of Control occurs prior to the end of the Restriction Period or (ii) in the event your employment terminates on account of the reasons set forth in Section 1(b)(ii) of this Agreement prior to the end of the Restriction Period, the Restricted Stock Units that vest in accordance with Section 1(b) of this Agreement will be paid within 30 business days following such Change of Control or the date of the termination of your employment, whichever applies. If Avient determines that it is required to withhold taxes from any payment, Avient will withhold Common Shares with a value equal to the amount of these taxes from the payment, and such Common Shares will be valued at an amount equal to the fair market value of such Common Shares on the date of payment.

(b)If the event triggering the right to payment under Section 3(a) of this Agreement does not constitute a permitted distribution event under Section 409A(a)(2) of the Code, then notwithstanding anything herein to the contrary, the payment of Common Shares will be made to you, to the extent necessary to comply with

Section 409A of the Code, on the earliest of (i) your “separation from service” with Avient or a Subsidiary (determined in accordance with Section 409A of the Code) that occurs after the event giving rise to payment; (ii) the Vesting Date applicable to the Restricted Stock Units attributable to such Common Shares; or (iii) your death. In addition, for the avoidance of doubt, Section 18(c) of the Plan applies to any payment of Common Shares made pursuant to this Agreement.

4.Dividend, Voting and Other Rights. You shall have no rights of ownership in the Restricted Stock Units or the Common Shares underlying the Restricted Stock Units and you shall have no right to vote the underlying Common Shares until the date on which any Common Shares are transferred to you pursuant to Section 3 of this Agreement. While the Restricted Stock Units are still outstanding, on the record date for each cash dividend, if any, that Avient pays to holders of Common Shares generally (the “Record Date”), you shall be entitled to a number of additional whole Restricted Stock Units determined by dividing (a) the product of (i) the dollar amount of the cash dividend paid per Common Share and (ii) the total number of Restricted Stock Units (including dividend equivalents paid thereon) credited to you as of the Record Date, by (b) the Market Value per Share on the Record Date. Any dividend equivalents credited hereunder shall be subject to the same terms and conditions and shall be settled or forfeited in the same manner and at the same time as the Restricted Stock Units to which the dividend equivalents were credited.

5.Non-Assignability. The Restricted Stock Units are personal to you and are not transferable by you other than by will or the laws of descent and distribution. Any purported transfer or encumbrance in violation of the provisions of this Section 5 shall be void, and the other party to any such purported transaction shall not obtain any right to or interest in such Restricted Stock Units.

6.Adjustments. In the event of any extraordinary cash dividend, stock dividend, stock split, combination of shares, recapitalization or other change in the capital structure of Avient, merger, consolidation, spin-off, split-off, spin-out, split-up, reorganization, partial or complete liquidation or other distribution of assets, issuance of rights or warrants to purchase securities, or any other corporate transaction or event having an effect similar to any of the foregoing, the Committee shall make or provide for such adjustments in the number of and kind of Common Shares covered by the Restricted Stock Units then held by you, and in other award terms, as the Committee, in its sole discretion, exercised in good faith, determines is equitably required to prevent dilution or enlargement of your rights in connection with such transaction or event. If any such transaction or event occurs or in the event of a Change of Control, the Committee may provide in substitution for outstanding Restricted Stock Units such alternative consideration (including, without limitation, in the form of cash, securities or other property) as it may determine to be equitable in the circumstances and shall require in connection therewith the surrender of the Restricted Stock Units subject to this Agreement. No adjustment provided for in this Section 6 or Section 12 of the Plan will require Avient to issue any fractional shares.

7.Miscellaneous.

(a)Construction. The contents of this Agreement are subject in all respects to the terms and conditions of the Plan as approved by the Board and the shareholders of Avient, which are controlling. The interpretation and construction by the Board and/or the Committee of any provision of the Plan or this Agreement shall be final and conclusive upon you, your estate, executor, administrator, beneficiaries, personal representative and guardian and Avient and its successors and assigns.

(b)Leave of Absence. Any absence or leave approved by a duly constituted officer of Avient or any of its Subsidiaries will not be considered an interruption or termination of your service under this Agreement.

(c)Data Privacy. The grant of the Restricted Stock Units is discretionary and will not be considered to be an employment contract or a part of your terms and conditions of employment or of your salary or compensation. Information about you and your participation in the Plan, including, without limitation, your name, home address, email address and telephone number, date of birth, social insurance number, passport number or other identification number, salary, nationality, job title, any shares of stock or directorships held in Avient, and details of the Restricted Stock Units or other entitlement to shares of stock awarded, cancelled, purchased, exercised, vested, unvested or outstanding in your favor may be collected, recorded, held, used and disclosed by Avient and any of its Subsidiaries and any non-Avient entities engaged by Avient to provide services in connection with this grant (a “Third Party Administrator”), for any purpose related to the administration of the Plan. You understand that Avient and its Subsidiaries may transfer such information to Third Party Administrators, regardless of whether such Third Party Administrators are located within your country of residence. Please refer to the Avient Global Associate Processing Notice, a copy of which has been provided or otherwise made available to you, for more information about the personal information that Avient collects about you and the purposes for which Avient uses such data. If you are a California resident, such notice is intended to satisfy Avient’s requirements under the California Consumer Protection Act.

(d)Amendment. Any amendment to the Plan shall be deemed to be an amendment to this Agreement to the extent that the amendment is applicable hereto. The terms and conditions of this Agreement may not be modified, amended or waived, except by an instrument in writing signed by a duly authorized executive officer at Avient. Notwithstanding the foregoing, no amendment shall adversely affect your rights under this Agreement without your consent.

(e)No Modifications to Existing Agreements. Except as specifically referenced herein, nothing in this Agreement impacts, changes, or otherwise modifies any existing agreements between you and Avient.

(f)Clawback. Notwithstanding anything in this Agreement to the contrary, you acknowledge and agree that (i) this Agreement, the Restricted Stock Units (and any settlement thereof) and any other performance-based incentive compensation or related amounts held or received by you are subject to any Avient clawback policy applicable to you, under their terms and conditions as may be in effect from time to time, including, without limitation, to implement Section 10D of the Exchange Act and any applicable rules or regulations (including applicable rules and regulations of any national securities exchange or national securities association on which the Common Shares may be traded) (the “Compensation Recovery Policy”), and (ii) that any relevant sections of this Agreement shall be deemed superseded by and subject to the terms and conditions of any such clawback policy from and after the effective date thereof. Further, by accepting the Restricted Stock Units covered by this Agreement, you (A) consent to be bound by the terms of the Compensation Recovery Policy, as applicable, (B) agree and acknowledge that you are obligated to and will cooperate with, and will provide any and all assistance necessary to, Avient in any effort to recover or recoup any compensation or other amounts subject to clawback or recovery

pursuant to the Compensation Recovery Policy and/or applicable laws, rules, regulations, stock exchange listing standards or other Avient policy, and (C) agree that Avient may enforce its rights under the Compensation Recovery Policy through any and all reasonable means permitted under applicable law as it deems necessary or desirable under the Compensation Recovery Policy. Such cooperation and assistance shall include (but is not limited to) executing, completing and submitting any documentation necessary, or consenting to action by Avient, to facilitate the recovery or recoupment by Avient from you of any such compensation or other amounts, including from your accounts or from any other compensation, to the extent permissible under Section 409A of the Code.

(g)Investigations. Notwithstanding anything to the contrary in this Agreement or in any other agreement, contract or arrangement with Avient or a Subsidiary, or in any policy, procedure or practice of Avient or a Subsidiary (collectively, the “Arrangements”), (i) nothing in the Arrangements or otherwise limits your right to any monetary award offered by a government-administered whistleblower award program for providing information directly to a government agency (including the Securities and Exchange Commission pursuant to Section 21F of the Exchange Act, the Dodd-Frank Wall Street Reform and Consumer Protection Act or The Sarbanes-Oxley Act of 2002), and (ii) nothing in the Arrangements or otherwise prevents you from, without prior notice to Avient, providing information (including documents) to governmental authorities or agencies regarding possible legal violations or otherwise testifying or participating in any investigation or proceeding by any governmental authorities or agencies regarding possible legal violations, and for purposes of clarity you are not prohibited from providing information (including documents) voluntarily to the Securities and Exchange Commission pursuant to Section 21F of the Exchange Act.

(iii)Equals or Exceeds Maximum. If, upon the conclusion of the Performance Period, Adjusted EPS equals or exceeds the maximum level, as set forth in the EPS Performance Matrix included in your Statement of Performance Goals, then 200% of the EPS Performance Units shall become earned.

(iv)Between Threshold and Target or Target and Maximum. If, upon the conclusion of the Performance Period, Adjusted EPS is greater than the threshold level, but less than the target level, or greater than the target level, but less than the maximum level, as set forth in the EPS Performance Matrix included in your Statement of Performance Goals, then a proportionate percentage of the EPS Performance Units shall become earned, as determined by mathematical interpolation and rounded up to the nearest whole unit.

(v)Below Threshold. In no event shall any EPS Performance Units become earned if actual performance for the Performance Period falls below the threshold level for Adjusted EPS or if the Committee does not certify that the Management Objectives have been satisfied with respect to the EPS Performance Units for the Performance Period.

(b)rTSR Performance Units. The rTSR Performance Units may be earned as follows:

(i)Threshold. If, upon the conclusion of the Performance Period, rTSR equals the threshold level, as set forth in the rTSR Performance Matrix included in your Statement of Performance Goals, then 50% of the rTSR Performance Units shall become earned.

(c)If the Committee determines that a change in the business, operations, corporate structure or capital structure of Avient, the manner in which it conducts business or other events or circumstances render the Management Objectives to be unsuitable, the Committee may modify such Management Objectives or the related levels of achievement, in whole or in part, as the Committee deems appropriate.

(d)Subject to the provisions of Sections 3 and 4 of this Agreement, your right to receive any Performance Units is contingent upon your remaining in the continuous employ of Avient or a Subsidiary through the payment date, which shall be a date in 2028 determined by the Committee (or its authorized delegatee) and shall occur no later than March 15, 2028 (the “Payment Date”).

(e)Notwithstanding the provisions of Section 4 of this Agreement and to the extent permitted by applicable law, a number of Performance Units may become non-forfeitable and payable prior to the Payment Date in an amount that is sufficient to cover any employment tax that becomes payable by you with respect to the Performance Units prior to the Payment Date.

3.Change of Control. Subject to Section 6,

(a)if a Change of Control occurs prior to the end of the Performance Period, Avient shall pay to you the total number of Performance Units granted under this Agreement (without regard to Section 2 of this Agreement) as soon as administratively practicable after, but in all events no later than 30 days following, the Change of Control.

5.Other Termination. If your employment with Avient or a Subsidiary terminates before the Payment Date for any reason other than as set forth in Section 4 above and before a Change of Control, the Performance Units will be forfeited.

(a)Payment of any Performance Units that become earned as set forth herein will be made in the form of cash. The amount of the cash payment to be made shall be determined by multiplying (i) the number of Performance Units earned pursuant to Section 2, 3 or 4 above by (ii) US$1.00.

(c)“Relative Total Shareholder Return” or “rTSR” shall mean the percentile rank of Avient’s Total Shareholder Return with respect to the Performance Period as compared to (but not included in) the Total Shareholder Returns for all members of the Peer Group, ranked in descending order, at the end of the Performance Period.

(d)“Total Shareholder Return” shall mean, with respect to the Common Shares and the shares of common stock of each of the members of the Peer Group, a rate of return reflecting stock price appreciation, plus the reinvestment of dividends in additional shares of stock, from the beginning of the Performance Period through the end of the Performance Period. In general, Total Shareholder Return shall be determined for each of Avient and each Peer Group entity as a percentage (rounded to the nearest two decimal places) based on the quotient of (i) the sum of (A) the difference between the Ending Average (as defined below) and the Beginning Average (as defined below) plus (B) dividends, divided by (ii) the Beginning Average. For purposes of calculating Total Shareholder Return for Avient and the members of the Peer Group, the beginning stock price will be based on the average closing price for the 20 trading days preceding the first day of the Performance Period on the principal stock exchange on which the stock is then traded (the “Beginning Average”), and the ending stock price will be based on the average closing price for the 20 trading days preceding and including the last day of the Performance Period (the “Ending Average”).

2. Peer Group Adjustments. The following adjustments will be made to the Peer Group during the Performance Period:

(a)If any member of the Peer Group (i) files for bankruptcy, reorganization, or liquidation under any chapter of the U.S. Bankruptcy Code or similar non-U.S. law (collectively, “bankruptcy”), (ii) is the subject of an involuntary bankruptcy proceeding that is not dismissed within 30 days, (iii) is the subject of a stockholder-approved plan of liquidation or dissolution or makes a general assignment for the benefit of creditors, or (iv) ceases to conduct substantial business operations (provided that, for the avoidance of doubt, (A) the acquisition of a member of the Peer Group by another person or group of related persons by itself does not result in the company being treated as ceasing to conduct substantial business operations, (B) any acquisition by an unaffiliated person or group of

related persons shall be subject to Section 2(b) below, and (C) treatment under this Section 2(a) shall not be affected by any subsequent reorganization, recapitalization or other restructuring pursuant to which the entity emerges from bankruptcy or otherwise continues or re-commences operations), then such entity will remain in the Peer Group, but Relative Total Shareholder Return for the Performance Period will be calculated as if such entity achieved Total Shareholder Return, placing it at the bottom (chronologically, if more than one such entity) of the Peer Group;

(b)If, by the end of the Performance Period, any member of the Peer Group has been acquired by an unaffiliated person or group of persons or is otherwise no longer existing as a publicly-traded company (other than for the reasons as described in Section 2(a) above), then such entity will be removed from the Peer Group; and

(c)Subject to Sections 2(a) and 2(b) above, if a member of the Peer Group undergoes an internal reorganization (e.g., inversion or establishment of a holding company structure) whereby the business and operations of the company (and its subsidiaries) constitute all the business and operations of the successor entity (and its subsidiaries) and the original member ceases to be publicly traded and such successor entity is publicly traded, such successor entity shall take the place of the original entity in the Peer Group.
