#### Avient Retirement Savings Plan

### Notes to Financial Statements

#### Note 1 — SUMMARY DESCRIPTION OF THE PLAN

#### General
The Avient Retirement Savings Plan (the Plan) is a defined contribution plan that covers substantially all employees of Avient Corporation (the Company or Plan Administrator) and its subsidiaries, in the United States, other than employees covered under a collective bargaining agreement unless such agreement calls for participation in the Plan, leased employees, nonresident aliens, other employees regularly employed outside of the United States, persons classified by the Company as anything other than employees (even if that classification is later changed) and employees of certain subsidiaries. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974, as amended (ERISA).

The following summary description of the Plan is provided for general information purposes only. Participants should refer to the Plan document for a more complete description of the Plan’s provisions.

The Plan is sponsored by the Company and is administered by the Avient Corporation Retirement Plan Committee (the Retirement Plan Committee).

#### Contributions
Employee

Participants may elect a bi-weekly payroll deduction from 1% to 90% of eligible earnings. The Retirement Plan Committee has the authority, at its discretion, to reduce the employees’ bi-weekly contribution percentage in order to maintain the tax-qualified status of the Plan.

The Plan offers participants the choice of pre-tax, after-tax and Roth savings options. Participants may elect to participate in one or more of the savings options. Under each savings option, participants may direct that contributions be invested in any eligible funds offered by the Plan. Participants may change their investment options daily.

The Plan provides for the acceptance of rollover contributions from other plans qualified under the Internal Revenue Code (IRC), provided certain conditions are met.

Employer

The Company provides for a matching contribution equal to 100% of the first 3% and 50% of the next 3% of the participant’s eligible deferred
