Key Details

• Transaction date: March 23, 2026; Form 4 filed March 25, 2026 (timely filing).

• Amounts: 50.00 DERs and 29.91 DERs (total 79.91 DERs); reported price $0.00; total reported value $0.
• Shares owned after transaction: Not specified in the filing.
• Relevant footnotes:
  • F1: DERs accrued with respect to additional time‑based RSUs credited for RSUs granted May 8, 2025 (each DER = economic equivalent of one share).
  • F2: When released, the RSUs tied to these DERs will be paid per the director’s election under the Koppers Director Deferred Compensation Plan (lump sum or annual installments beginning on the May 31 after separation or a later elected year).
  • F3: DERs also relate to additional RSUs credited with respect to deferred compensation.

Context These are derivative awards (DERs) tied to RSUs and represent future economic exposure to Koppers common stock rather than immediate share ownership or a market purchase/sale. Payment or conversion timing depends on the director’s deferred‑compensation election under the Plan. This filing reports an award (not a sale or open‑market purchase) and does not, by itself, indicate a change in the director’s immediate voting ownership.
