What Happened

Key Details

• Transaction date: 2026-06-15 (reported on Form 4 filed 2026-06-17).
• Transaction type/code: Grant/Award (A) of 13.979 DERs at $0.00.
• Shares owned after transaction: Not specified in the filing.
• Footnote F1: DERs accrue with respect to additional restricted stock units (RSUs); each DER equals the economic equivalent of one share of Koppers common stock.
• Footnote F2: Once released, the RSUs tied to these DERs will be paid per the director deferred compensation plan election—either a lump sum or annual installments beginning on the May 31 following separation (or a later year if elected).
• Timeliness: Filing appears timely (Form 4 filed two days after the transaction).

Context
This is a derivative compensation award (deferred-equivalent RSUs), not a market purchase or sale. Such grants reflect compensation/deferral elections and do not by themselves indicate an immediate purchase signal or sale pressure. The award will convert to RSUs/share equivalents and be paid out according to the director deferred compensation plan terms when released.
