Use of Non-GAAP Measures This presentation includes the use of both GAAP (generally accepted accounting principles) and non-GAAP financial measures. The non-GAAP financial measures include: adjusted EPS, adjusted operating income, free cash flow and adjusted EBITDA. A reconciliation of each non-GAAP financial measure with the most directly comparable GAAP financial measure is attached to this presentation which is posted on our website at www.avient.com.

The non-GAAP financial measures include: Adjusted Earnings Per Share, Net Debt/Adjusted EBITDA and Adjusted EBITDA. EBITDA and Adjusted EBITDA are non-GAAP financial measures that management uses in evaluating operating performance. The presentation of these measures may be different from non-GAAP financial measures used by other companies.
