  1. Effective March 31, 2026 (the "2023 PBRSU Certification Date"), the Executive Committee of the Board of Directors of Park National Corporation ("Park") certified the level of achievement with respect to the performance criteria for the three-fiscal-year performance period applicable to performance-based restricted stock units ("PBRSUs") granted to the reporting person effective January 18, 2023. The PBRSUs convert into Park common shares on a one-for-one basis. The PBRSUs earned based on the performance level achieved are also subject to a service-based vesting requirement with 50% vesting (resulting in the right to receive the number of common shares shown in the first row in Table I) on the 2023 PBRSU Certification Date and the other 50% to vest on the first anniversary of the 2023 PBRSU Certification Date (shown in the second row in Table II as a derivative security). In the April 2, 2026 Form 4, an estimated number of Park common shares was reported as being withheld by Park in order to satisfy the tax withholding obligations of the reporting person that arose upon the vesting of the PBRSUs which were not subject to the service-based vesting requirement described in footnote (1) and the vesting of the PBRSUs that had been subject to the service-based vesting requirement described in footnote (3), as applicable. This amendment reports the correct number of common shares withheld. These common shares of Park were acquired upon the satisfaction of a service-based vesting requirement whereby PBRSUs were converted into Park common shares on a one-for-one basis.

performance-based restricted stock units financial
"performance-based restricted stock units ("PBRSUs") granted to the reporting person"
Performance-based restricted stock units are a type of employee equity award that converts into company shares only if predefined financial or operational targets are met over a set period. Think of it like a bonus check that becomes stock only when specific goals are hit; it ties pay to results, aligning managers’ incentives with shareholders. Investors care because these awards affect future share count, executive incentives, and signal how management’s success will be measured and rewarded.
