Footnote F5

On January 3, 2025, the reporting person was granted performance share units ("PSUs") for which the performance criteria for the one-year performance period from January 1, 2025 through December 31, 2025 have been satisfied. All of the restricted stock units reported here are subject to vesting based on the continued service of the reporting person through January 5, 2028. If the Company's total shareholder return over the three-year period of January 1, 2025 through December 31, 2027 is negative, then the cumulative number of units that may vest for such three-year period will be capped at 150% of the target number.

Footnote F7

These DERs were released in connection with the vesting of RSUs granted on January 4, 2022, January 4, 2023, January 4, 2024, and January 3, 2025. Each DER is the economic equivalent of one share of Koppers Holdings Inc. common stock.
