Without giving effect to any impacts from the pending acquisition of Dyneema and potential sale of Avient Distribution, the company provided third quarter adjusted EPS guidance of $0.80, a 14% increase from the prior year quarter, and maintained its full year adjusted EPS guidance of $3.50. Senior management believes these measures are useful to investors because they allow for comparison to Avient's performance in prior periods without the effect of items that, by their nature, tend to obscure Avient's operating results due to the potential variability across periods based on timing, frequency and magnitude. In addition, operating income before the effect of special items is a component of Avient annual and long-term employee incentive plans and is used in debt covenant computations.
