• Reported entries: 50 DERs @ $0.00 and 25.35 DERs @ $0.00 — total 75.35 DERs.

• Footnotes (summary):
  • F1: The DERs accrued with respect to additional time‑based RSUs credited related to RSUs granted May 8, 2025; each DER equals the economic equivalent of one share.
  • F2: Once released, the RSUs tied to these DERs will be paid according to the reporting person's election under the Koppers Director Deferred Compensation Plan (lump sum or annual installments beginning May 31 following separation or a later elected year).
  • F3: The DERs also reflect accruals related to deferred compensation.
• Transaction code: A = award/grant (derivative).

Context

• These DERs are deferred-compensation/award instruments that represent the economic equivalent of shares once released; they do not represent immediate shares sold or purchased in the market.
• Awards like this are common for board compensation and do not necessarily signal the director buying or selling stock; they increase potential future exposure to company stock based on vesting/release terms.
